Summary In this episode of the Pain Exam Podcast, Dr. David Rosenblum provides a comprehensive review of herpes zoster and postherpetic neuralgia (PHN), focusing on pathophysiology, diagnosis, and treatment options. Dr. Rosenblum explains that postherpetic neuralgia affects approximately 25% of patients with acute herpes zoster, causing debilitating unilateral chronic pain in one or more dermatomes. He discusses the three phases of herpes zoster: acute (up to 30 days), subacute (up to 3 months), and postherpetic neuralgia (pain continuing beyond 3 months). Dr. Rosenblum identifies risk factors for developing PHN, including older age, female sex, immunosuppression, prodromal pain, severe rash, and greater acute pain severity. He details the pathophysiology involving peripheral and central sensitization, and explains different phenotypes of PHN that can guide treatment approaches. For treatment, Dr. Rosenblum reviews various options including antiviral medications (which should be started within 72 hours of onset), corticosteroids, opioids, antidepressants (particularly tricyclics and SNRIs), antiepileptics (gabapentin and pregabalin), topical agents (lidocaine and capsaicin), and interventional procedures such as epidural injections and pulsed radiofrequency. He emphasizes that prevention through vaccination with Shingrix is highly effective, with 97% effectiveness in preventing herpes zoster in patients 50-69 years old and 89% effectiveness in those over 70. Dr. Rosenblum mentions that he's currently treating a patient with trigeminal postherpetic neuralgia and is considering a topical sphenopalatine ganglion block as a minimally invasive intervention before attempting more invasive procedures. Chapters Introduction to the Pain Exam Podcast and Topic Overview Dr. David Rosenblum introduces the Pain Exam Podcast, mentioning that it covers painful disorders, alternative treatments, and practice management. He explains that this episode focuses on herpes zoster and postherpetic neuralgia as board preparation for fellows starting their programs, with ABA boards coming up in September. Dr. Rosenblum notes that he's not only preparing listeners for boards but also seeking the latest information to help treat his own patients with this notoriously difficult disease. Upcoming Conferences and Educational Opportunities Dr. Rosenblum announces several upcoming conferences including Aspen in July, Pain Week in September, and events with NYSIP and the Latin American Pain Society. He mentions he'll be teaching ultrasound and regenerative medicine at these events. Dr. Rosenblum invites listeners to sign up at nrappain.org to access a community discussing regenerative medicine, ultrasound-guided pain medicine, regional anesthesia, and board preparation. He also offers ultrasound training in New York and elsewhere, with upcoming sessions in Manhattan on July 12th and October 4th, plus private shadowing opportunities. Overview of Postherpetic Neuralgia Dr. Rosenblum defines postherpetic neuralgia as typically a unilateral chronic pain in one or more dermatomes after acute herpes zoster infection. He states that the incidence of acute herpes zoster ranges between 3-5 patients per thousand person-years, and one in four patients with acute herpes zoster-related pain will transition into postherpetic neuralgia. Dr. Rosenblum emphasizes that while this condition won't kill patients, it can be extremely debilitating and significantly reduce quality of life. Treatment Options Overview Dr. Rosenblum reviews treatment options according to the WHO pain ladder, including tricyclics like nortriptyline and antiepileptic drugs such as gabapentin. He explains that if pain is not significantly reduced, interventional treatments like epidural injections with local anesthetics and corticosteroids or pulsed radiofrequency of the dorsal root ganglion are options. For postherpetic neuralgia specifically, Dr. Rosenblum notes that preferred treatments include transdermal capsaicin, lidocaine, or oral drugs such as antidepressants or antiepileptics. Phases of Herpes Zoster and Definitions Dr. Rosenblum outlines the three phases during herpes zoster reactivation: acute herpes zoster-related pain (lasting maximum 30 days), subacute herpes zoster-related pain (pain after healing of vesicles but disappearing within 3 months), and postherpetic neuralgia (typically defined as pain continuing after 3 months). He mentions that acute herpes zoster pain often begins with prodromal pain starting a few days before the appearance of the rash. Incidence and Risk Factors Dr. Rosenblum states that the incidence of herpes zoster ranges between 3-5 patients per 1,000 person-years, with approximately 5-30% of cases leading to postherpetic neuralgia. He identifies risk factors including older age, female sex, immunosuppression, prodromal pain, severe rash, and greater acute pain severity. Dr. Rosenblum describes the clinical manifestations as a mosaic of somatosensory symptoms including burning, deep aching pain, tingling, itching, stabbing, often associated with tactile and cold allodynia. Impact on Quality of Life Dr. Rosenblum emphasizes that postherpetic neuralgia can be debilitating, impacting both physical and emotional functioning and causing decreased quality of life. He notes that it leads to fatigue, insomnia, depression, anorexia, anxiety, and emotional distress. Dr. Rosenblum stresses the importance of exploring methods for prevention of postherpetic neuralgia and optimizing pain treatment for both subacute herpes zoster-related pain and postherpetic neuralgia. Literature Review and Pathophysiology Dr. Rosenblum mentions that he's discussing a literature review from 2024 that updates previous practical guidelines published in 2011. He explains the pathophysiology of postherpetic neuralgia, which involves sensitization of peripheral and sensory nerves from damage. Dr. Rosenblum describes how inflammatory mediators reduce the stimulus threshold of nociceptors and increase responsiveness, resulting in pathological spontaneous discharges, lower thresholds for thermal and mechanical stimuli, and hyperalgesia. Central Sensitization and Nerve Damage Dr. Rosenblum explains that central sensitization results from peripheral nociceptor hyperactivity leading to plastic changes in the central nervous system, involving amplification of pain signals and reduced inhibition. He describes how nerve damage in postherpetic neuralgia patients results from neuronal death due to severe inflammatory stimuli or secondary to neuronal swelling. Dr. Rosenblum notes that motor defects occur in 0.05% of patients with herpes zoster, observed as abdominal pseudohernias or motor weakness of limbs limited to the affected myotome. Different Phenotypes and Classification Dr. Rosenblum discusses different phenotypes of postherpetic neuralgia and how phenotyping can determine treatment. He explains that there are several ways to classify the phenotypes, with one categorizing patients into three subtypes: sensory loss (most common), thermal gain, and thermal loss with mechanical gain. Dr. Rosenblum describes the mechanistic categorization, including the irritable nociceptive phenotype characterized by preserved sensation, profound dynamic mechanical allodynia, reduced pressure pain threshold, and relief with local anesthetic infiltration. Deafferentation Phenotype Dr. Rosenblum explains that a deafferentation phenotype may arise from destruction of neurons by the virus in the dorsal root ganglion. This phenotype is characterized by sensory loss, including thermal and vibratory sensation without prominent thermal allodynia. He notes that mechanical allodynia can occur secondary to A-beta fibers activating spinothalamic pathways (known as phenotypic switches), along with pressure hyperalgesia and temporal summation suggesting central sensitization. Dr. Rosenblum mentions that in one study, this phenotype was present in 10.8% of individuals, and for those with deafferentation pain, gabapentinoids, antidepressants, and neuromodulatory therapies like repetitive transcranial magnetic stimulation may be beneficial. Diagnosis and Physical Examination Dr. Rosenblum discusses the diagnosis of herpes zoster and postherpetic neuralgia, emphasizing the importance of physical examination. He explains that diagnosis is based on the rash, redness, papules, and vesicles in the painful dermatomes, with healing vesicles showing crust formation. Dr. Rosenblum notes that the rash is generally unilateral and does not cross the midline of the body. In postherpetic neuralgia patients, he mentions that scarring, hyper or hypopigmentation is often visible, with allodynia present in 45-75% of affected patients. Sensory Testing and Assessment Dr. Rosenblum explains that in patients with postherpetic neuralgia, a mosaic of somatosensory alterations can occur, manifesting as hyperalgesia, allodynia, and sensory loss. These can be quantified by quantitative sensory testing, which assesses somatosensory functions, dermal detection thresholds for perception of cold, warmth, and paradoxical heat sensations. He notes that testing can provide clues regarding underlying mechanisms of pain, impaired conditioned pain modulation, temporal summation suggesting central sensitization, and information about the type of nerve damage and surviving afferent neurons. Prevention Through Vaccination Dr. Rosenblum discusses prevention of acute herpes zoster through vaccination, noting that the risk increases with reduced immunity. He highlights studies evaluating Shingrix, a vaccine for herpes zoster, which showed 97% effectiveness in preventing herpes zoster in patients 50-69 years old with healthy immune systems and 89% effectiveness in patients over 70. Dr. Rosenblum states that Shingrix is 89-91% effective in preventing postherpetic neuralgia development in patients with healthy immune systems and 68-91% effective in those with weakened or underlying conditions. Treatment Objectives Dr. Rosenblum outlines the treatment objectives for herpes zoster and postherpetic neuralgia. For acute herpes zoster, objectives include relieving pain, reducing severity and duration of pain, accelerating recovery of epidermal defects, and preventing secondary infections. For postherpetic neuralgia, the objectives are pain alleviation and improved quality of life. Dr. Rosenblum lists available treatments including psychotherapy, opiates, antidepressants, antiepileptics, NMDA antagonists, topical agents, and interventional treatments such as epidurals, pulsed radiofrequency, nerve blocks, and spinal cord stimulation. Antiviral Medications Dr. Rosenblum emphasizes that antiviral drugs should be started within 72 hours of clinical onset, mentioning famciclovir, valacyclovir, and acyclovir. He notes there is no evidence for effectiveness after 72 hours in patients with uncomplicated herpes zoster. Dr. Rosenblum provides dosing information: for immunocompetent patients, famciclovir 500mg and valacyclovir 1000mg three times daily for seven days; for immunocompromised patients, famciclovir 1000mg three times daily for 10 days, while acyclovir should be given IV in the immunocompromised. Benefits of Antiviral Therapy Dr. Rosenblum explains that antiviral medication accelerates the disappearance of vesicles and crusts, promotes healing of skin lesions, and prevents new lesions from forming. By inhibiting viral replication, he notes that antiviral therapy likely reduces nerve damage, resulting in reduced incidence of postherpetic neuralgia, and should be started as soon as possible. Corticosteroids and Opioids Dr. Rosenblum discusses the use of corticosteroids, noting that when added to antiviral medications, they may reduce the severity of acute herpes zoster-related pain, though increased healing of skin lesions was not observed in one study. He mentions that a Cochrane review found oral corticosteroids ineffective in preventing postherpetic neuralgia. Regarding opioids, Dr. Rosenblum states they are commonly used alongside antivirals for controlling acute herpes zoster pain, with tramadol having a number needed to treat (NNT) of 4.7 and strong opioids having an NNT of 4.3 for 50% pain reduction. Methadone and Antidepressants Dr. Rosenblum discusses methadone as an NMDA receptor antagonist used in acute and chronic pain management, though he notes there are no randomized controlled trials determining its efficacy in acute herpes zoster pain or postherpetic neuralgia. He explains that methadone can modulate pain stimuli by inhibiting the uptake of norepinephrine and serotonin, resulting in decreased development of hyperalgesia and opioid tolerance, but has side effects including constipation, nausea, sedation, and QT prolongation that can trigger torsades de pointes. Dr. Rosenblum identifies antidepressants as first-line therapy for postherpetic neuralgia, including tricyclics and SNRIs, with tricyclics having an NNT of 3 and SNRIs an NNT of 6.4 for 50% pain reduction. Antiepileptics and Pharmacological Treatment Summary Dr. Rosenblum discusses antiepileptics like gabapentin and pregabalin for postherpetic neuralgia. He cites two trials measuring gabapentin's effect, concluding it was effective compared to placebo with a pooled NNT of 4.4, while pregabalin had an NNT of 4.9. Dr. Rosenblum summarizes that pharmacological treatment is well established for subacute herpes zoster pain, though new high-quality evidence has been lacking since the last update in 2011. Topical Agents Dr. Rosenblum discusses local anesthetic topical agents including lidocaine and capsaicin creams and patches. He notes that 8% capsaicin provided significant pain reduction during 2-8 weeks, while 5% lidocaine patches provided moderate pain relief after eight weeks of treatment. Dr. Rosenblum also mentions acute herpes zoster intracutaneous injections, citing a study where single intracutaneous injection with methylprednisolone combined with ropivacaine versus saline alone showed significant difference in VAS score at 1 and 4 weeks post-intervention favoring the intervention group. Intracutaneous Injections Dr. Rosenblum discusses the effect of repetitive intracutaneous injections with ropivacaine and methylprednisolone every 48 hours for one week. He cites a randomized control trial comparing antivirals plus analgesics to antivirals plus analgesics and repeat injections, finding the intervention group had significantly shorter duration of pain, lower VAS scores, and lower incidence of postherpetic neuralgia (6.4% vs 28% at 3 months). Dr. Rosenblum notes that a potential side effect of cutaneous methylprednisolone injection is fat atrophy, though this wasn't reported in the study. Summary of Local Anesthetics Dr. Rosenblum summarizes that there are no new studies reporting the efficacy of capsaicin 8% for postherpetic neuralgia, but it remains widely used in clinical practice and is approved in several countries. He notes that lidocaine patches can reduce pain intensity in patients with postherpetic neuralgia but may be more beneficial in patients with allodynia. Dr. Rosenblum adds that intracutaneous injections may be helpful for short periods, while repetitive injections with local anesthetics may reduce VAS scores for up to six months but can cause subcutaneous fat atrophy. Interventional Treatments: Epidural and Paravertebral Injections Dr. Rosenblum discusses interventional treatments, noting that previous guidelines found epidural injection with corticosteroids and local anesthetic as add-on therapy superior to standard care alone for up to one month in managing acute herpes zoster pain. He mentions a randomized controlled trial showing no difference between interlaminar and transforaminal epidural steroid injections for up to three months after the procedure. Dr. Rosenblum adds that previous guidelines reported high-quality evidence that paravertebral injections of corticosteroids or local anesthetic reduces pain in the active phase of herpes zoster. Comparative Studies on Injection Approaches Dr. Rosenblum discusses a trial comparing efficacy of repetitive paravertebral blocks with ropivacaine versus dexmedetomidine to prevent postherpetic neuralgia, which showed significantly lower incidence of zoster-related pain one month after therapy in the dexmedetomidine group, with effects still significant at three months. He also mentions a study comparing steroid injections administered via interlaminar versus transforaminal approaches, finding both groups had significantly lower VAS scores at 1 and 3 months follow-up compared to baseline, though this could align with the natural course of herpes zoster. Timing of Interventions and Continuous Epidural Blockade Dr. Rosenblum cites a retrospective study showing that transforaminal epidural injections administered for acute herpes zoster-related pain were associated with significantly shorter time to pain relief compared to those performed in the subacute phase. He also mentions a randomized controlled trial finding that continuous epidural blockade combined with opioids and gabapentin reduced NRS pain scores more than analgesic drug treatments alone during three-day follow-up, though both studies were low-quality. Interventions for Postherpetic Neuralgia Dr. Rosenblum discusses interventions specifically for postherpetic neuralgia, citing a small randomized controlled trial that demonstrated decreased NRS pain scores six months post-treatment for repeat versus single epidural steroid injections (15mg vs 5mg dexamethasone) administered over 24 days. The trial also found increased likelihood of complete remission during 6-month follow-up in the group receiving repeat epidural dexamethasone, though this was low-quality evidence. Summary of Epidural and Paravertebral Injections Dr. Rosenblum summarizes that epidural or paravertebral injections of local anesthetic and/or glucocorticoids could be considered in treating acute herpes zoster-related pain. For subacute postherpetic neuralgia pain, he notes low-quality evidence supporting epidural injections, while for postherpetic neuralgia, evidence supports continuous epidural infusion, though also of low quality. Dr. Rosenblum emphasizes that none of the included studies for postherpetic neuralgia investigating epidural or paravertebral injections resulted in decreased pain compared to standard therapy. Pulsed Radiofrequency (PRF) Evidence Dr. Rosenblum discusses pulsed radiofrequency (PRF), noting that previous guidelines indicated moderate quality evidence that PRF of the intercostal nerve reduces pain for 6 months in patients with postherpetic neuralgia, and very low-quality evidence that PRF to the dorsal root ganglion (DRG) reduces pain for 6 months. He mentions that multiple studies have been published since then assessing PRF efficacy. PRF Studies for Acute Herpes Zoster Dr. Rosenblum discusses a randomized controlled trial with 60 patients comparing high-voltage bipolar PRF of the cervical sympathetic chain versus sham, with treatment repeated after three days in both groups. He reports that VAS scores in the PRF group at each post-interventional point (1 day, 2 days, 1 month, 2 months, 3 months) were significantly lower than in the sham group, and at 3 months, the incidence of postherpetic neuralgia was 16.7% in the PRF group compared to 40% in the sham group. PRF for Trigeminal Neuralgia Dr. Rosenblum cites another randomized controlled trial evaluating high-voltage long-duration PRF of the Gasserian ganglion in 96 patients with subacute herpes-related trigeminal neuralgia, which found decreased VAS pain scores at all post-interventional time points (3, 7, 14 days and 1, 3, and 6 months) compared to the sham group. He also mentions a randomized comparative effectiveness study in 120 patients with subacute trigeminal herpes zoster, comparing a single application of high-voltage PRF to the Gasserian ganglion versus three cycles of conventional PRF treatment, finding significantly lower mean VAS pain scores for up to six months in the high-voltage PRF group. PRF Compared to Other Interventions Dr. Rosenblum discusses a randomized controlled trial comparing PRF to short-term spinal cord stimulation, which found decreased pain and improved 36-item short-form health survey scores in both groups at six months. He also mentions a randomized controlled trial in 72 patients where PRF of spinal nerves or peripheral branches of cranial nerves combined with five-day infusion of IV lidocaine resulted in greater pain reduction, less rescue analgesia, and reduced inflammatory cytokines at two months compared to PRF with saline infusions. Dr. Rosenblum notes a major limitation of this study was not accounting for the high natural recovery rate. Summary of PRF and Final Recommendations Dr. Rosenblum summarizes that PRF provides significant pain relief lasting over three months in patients with subacute herpes zoster and postherpetic neuralgia. He notes that since few studies have compared PRF versus sham, it's not possible to calculate an accurate number needed to treat. Dr. Rosenblum mentions there are no comparative studies comparing PRF to the intercostal nerves versus PRF of the DRG, but both preclinical and clinical studies suggest superiority of the DRG approach. He adds that evidence for spinal cord stimulation for postherpetic neuralgia is of low quality, and more research is needed given its invasive nature. Sympathetic Blocks and Conclusion Dr. Rosenblum notes there is low-quality evidence for using sympathetic blocks to treat acute herpes zoster-related pain, but no evidence for their use in postherpetic neuralgia. He mentions that risks of treatment with intrathecal methylprednisolone are unclear and therefore not recommended. Dr. Rosenblum concludes by praising the comprehensive article he's been discussing and mentions it provides insight for treating his patients, including a recent case of trigeminal postherpetic neuralgia. Personal Clinical Approach and Closing Dr. Rosenblum shares that he doesn't currently perform PRF in his practice, partly because it's not standard of care and not well reimbursed, creating barriers to implementation. However, he notes that PRF is a very safe procedure as it doesn't involve burning tissue. For his patient with trigeminal neuralgia pain, Dr. Rosenblum plans to try a topical sphenopalatine ganglion block as the least invasive intervention before considering injecting the trigeminal nerves at the foramen, in addition to pharmacotherapy. He concludes by thanking listeners, encouraging them to check the show notes and links, mentioning institutional memberships and shadowing opportunities, and asking listeners to rate and share the podcast.

Summary In this episode of the Pain Exam Podcast, Dr. David Rosenblum provides a comprehensive review of herpes zoster and postherpetic neuralgia (PHN), focusing on pathophysiology, diagnosis, and treatment options. Dr. Rosenblum explains that postherpetic neuralgia affects approximately 25% of patients with acute herpes zoster, causing debilitating unilateral chronic pain in one or more dermatomes. He discusses the three phases of herpes zoster: acute (up to 30 days), subacute (up to 3 months), and postherpetic neuralgia (pain continuing beyond 3 months).

Overview of Postherpetic Neuralgia Dr. Rosenblum defines postherpetic neuralgia as typically a unilateral chronic pain in one or more dermatomes after acute herpes zoster infection. He states that the incidence of acute herpes zoster ranges between 3-5 patients per thousand person-years, and one in four patients with acute herpes zoster-related pain will transition into postherpetic neuralgia.

He identifies risk factors including older age, female sex, immunosuppression, prodromal pain, severe rash, and greater acute pain severity. Dr. Rosenblum describes the clinical manifestations as a mosaic of somatosensory symptoms including burning, deep aching pain, tingling, itching, stabbing, often associated with tactile and cold allodynia. Impact on Quality of Life Dr. Rosenblum emphasizes that postherpetic neuralgia can be debilitating, impacting both physical and emotional functioning and causing decreased quality of life. He notes that it leads to fatigue, insomnia, depression, anorexia, anxiety, and emotional distress. Dr. Rosenblum stresses the importance of exploring methods for prevention of postherpetic neuralgia and optimizing pain treatment for both subacute herpes zoster-related pain and postherpetic neuralgia.

He mentions that a Cochrane review found oral corticosteroids ineffective in preventing postherpetic neuralgia. Regarding opioids, Dr. Rosenblum states they are commonly used alongside antivirals for controlling acute herpes zoster pain, with tramadol having a number needed to treat (NNT) of 4.7 and strong opioids having an NNT of 4.3 for 50% pain reduction. Methadone and Antidepressants Dr. Rosenblum discusses methadone as an NMDA receptor antagonist used in acute and chronic pain management, though he notes there are no randomized controlled trials determining its efficacy in acute herpes zoster pain or postherpetic neuralgia. He explains that methadone can modulate pain stimuli by inhibiting the uptake of norepinephrine and serotonin, resulting in decreased development of hyperalgesia and opioid tolerance, but has side effects including constipation, nausea, sedation, and QT prolongation that can trigger torsades de pointes. Dr. Rosenblum identifies antidepressants as first-line therapy for postherpetic neuralgia, including tricyclics and SNRIs, with tricyclics having an NNT of 3 and SNRIs an NNT of 6.4 for 50% pain reduction. Antiepileptics and Pharmacological Treatment Summary Dr. Rosenblum discusses antiepileptics like gabapentin and pregabalin for postherpetic neuralgia. He cites two trials measuring gabapentin's effect, concluding it was effective compared to placebo with a pooled NNT of 4.4, while pregabalin had an NNT of 4.9. Dr. Rosenblum summarizes that pharmacological treatment is well established for subacute herpes zoster pain, though new high-quality evidence has been lacking since the last update in 2011. Topical Agents Dr. Rosenblum discusses local anesthetic topical agents including lidocaine and capsaicin creams and patches. He notes that 8% capsaicin provided significant pain reduction during 2-8 weeks, while 5% lidocaine patches provided moderate pain relief after eight weeks of treatment. Dr. Rosenblum also mentions acute herpes zoster intracutaneous injections, citing a study where single intracutaneous injection with methylprednisolone combined with ropivacaine versus saline alone showed significant difference in VAS score at 1 and 4 weeks post-intervention favoring the intervention group. Intracutaneous Injections Dr. Rosenblum discusses the effect of repetitive intracutaneous injections with ropivacaine and methylprednisolone every 48 hours for one week. He cites a randomized control trial comparing antivirals plus analgesics to antivirals plus analgesics and repeat injections, finding the intervention group had significantly shorter duration of pain, lower VAS scores, and lower incidence of postherpetic neuralgia (6.4% vs 28% at 3 months). Dr. Rosenblum notes that a potential side effect of cutaneous methylprednisolone injection is fat atrophy, though this wasn't reported in the study. Summary of Local Anesthetics Dr. Rosenblum summarizes that there are no new studies reporting the efficacy of capsaicin 8% for postherpetic neuralgia, but it remains widely used in clinical practice and is approved in several countries. He notes that lidocaine patches can reduce pain intensity in patients with postherpetic neuralgia but may be more beneficial in patients with allodynia. Dr. Rosenblum adds that intracutaneous injections may be helpful for short periods, while repetitive injections with local anesthetics may reduce VAS scores for up to six months but can cause subcutaneous fat atrophy. Interventional Treatments: Epidural and Paravertebral Injections Dr. Rosenblum discusses interventional treatments, noting that previous guidelines found epidural injection with corticosteroids and local anesthetic as add-on therapy superior to standard care alone for up to one month in managing acute herpes zoster pain. He mentions a randomized controlled trial showing no difference between interlaminar and transforaminal epidural steroid injections for up to three months after the procedure. Dr. Rosenblum adds that previous guidelines reported high-quality evidence that paravertebral injections of corticosteroids or local anesthetic reduces pain in the active phase of herpes zoster. Comparative Studies on Injection Approaches Dr. Rosenblum discusses a trial comparing efficacy of repetitive paravertebral blocks with ropivacaine versus dexmedetomidine to prevent postherpetic neuralgia, which showed significantly lower incidence of zoster-related pain one month after therapy in the dexmedetomidine group, with effects still significant at three months. He also mentions a study comparing steroid injections administered via interlaminar versus transforaminal approaches, finding both groups had significantly lower VAS scores at 1 and 3 months follow-up compared to baseline, though this could align with the natural course of herpes zoster. Timing of Interventions and Continuous Epidural Blockade Dr. Rosenblum cites a retrospective study showing that transforaminal epidural injections administered for acute herpes zoster-related pain were associated with significantly shorter time to pain relief compared to those performed in the subacute phase. He also mentions a randomized controlled trial finding that continuous epidural blockade combined with opioids and gabapentin reduced NRS pain scores more than analgesic drug treatments alone during three-day follow-up, though both studies were low-quality. Interventions for Postherpetic Neuralgia Dr. Rosenblum discusses interventions specifically for postherpetic neuralgia, citing a small randomized controlled trial that demonstrated decreased NRS pain scores six months post-treatment for repeat versus single epidural steroid injections (15mg vs 5mg dexamethasone) administered over 24 days. The trial also found increased likelihood of complete remission during 6-month follow-up in the group receiving repeat epidural dexamethasone, though this was low-quality evidence. Summary of Epidural and Paravertebral Injections Dr. Rosenblum summarizes that epidural or paravertebral injections of local anesthetic and/or glucocorticoids could be considered in treating acute herpes zoster-related pain. For subacute postherpetic neuralgia pain, he notes low-quality evidence supporting epidural injections, while for postherpetic neuralgia, evidence supports continuous epidural infusion, though also of low quality. Dr. Rosenblum emphasizes that none of the included studies for postherpetic neuralgia investigating epidural or paravertebral injections resulted in decreased pain compared to standard therapy. Pulsed Radiofrequency (PRF) Evidence Dr. Rosenblum discusses pulsed radiofrequency (PRF), noting that previous guidelines indicated moderate quality evidence that PRF of the intercostal nerve reduces pain for 6 months in patients with postherpetic neuralgia, and very low-quality evidence that PRF to the dorsal root ganglion (DRG) reduces pain for 6 months. He mentions that multiple studies have been published since then assessing PRF efficacy. PRF Studies for Acute Herpes Zoster Dr. Rosenblum discusses a randomized controlled trial with 60 patients comparing high-voltage bipolar PRF of the cervical sympathetic chain versus sham, with treatment repeated after three days in both groups. He reports that VAS scores in the PRF group at each post-interventional point (1 day, 2 days, 1 month, 2 months, 3 months) were significantly lower than in the sham group, and at 3 months, the incidence of postherpetic neuralgia was 16.7% in the PRF group compared to 40% in the sham group. PRF for Trigeminal Neuralgia Dr. Rosenblum cites another randomized controlled trial evaluating high-voltage long-duration PRF of the Gasserian ganglion in 96 patients with subacute herpes-related trigeminal neuralgia, which found decreased VAS pain scores at all post-interventional time points (3, 7, 14 days and 1, 3, and 6 months) compared to the sham group. He also mentions a randomized comparative effectiveness study in 120 patients with subacute trigeminal herpes zoster, comparing a single application of high-voltage PRF to the Gasserian ganglion versus three cycles of conventional PRF treatment, finding significantly lower mean VAS pain scores for up to six months in the high-voltage PRF group. PRF Compared to Other Interventions Dr. Rosenblum discusses a randomized controlled trial comparing PRF to short-term spinal cord stimulation, which found decreased pain and improved 36-item short-form health survey scores in both groups at six months. He also mentions a randomized controlled trial in 72 patients where PRF of spinal nerves or peripheral branches of cranial nerves combined with five-day infusion of IV lidocaine resulted in greater pain reduction, less rescue analgesia, and reduced inflammatory cytokines at two months compared to PRF with saline infusions. Dr. Rosenblum notes a major limitation of this study was not accounting for the high natural recovery rate. Summary of PRF and Final Recommendations Dr. Rosenblum summarizes that PRF provides significant pain relief lasting over three months in patients with subacute herpes zoster and postherpetic neuralgia. He notes that since few studies have compared PRF versus sham, it's not possible to calculate an accurate number needed to treat. Dr. Rosenblum mentions there are no comparative studies comparing PRF to the intercostal nerves versus PRF of the DRG, but both preclinical and clinical studies suggest superiority of the DRG approach. He adds that evidence for spinal cord stimulation for postherpetic neuralgia is of low quality, and more research is needed given its invasive nature. Sympathetic Blocks and Conclusion Dr. Rosenblum notes there is low-quality evidence for using sympathetic blocks to treat acute herpes zoster-related pain, but no evidence for their use in postherpetic neuralgia. He mentions that risks of treatment with intrathecal methylprednisolone are unclear and therefore not recommended. Dr. Rosenblum concludes by praising the comprehensive article he's been discussing and mentions it provides insight for treating his patients, including a recent case of trigeminal postherpetic neuralgia. Personal Clinical Approach and Closing Dr. Rosenblum shares that he doesn't currently perform PRF in his practice, partly because it's not standard of care and not well reimbursed, creating barriers to implementation. However, he notes that PRF is a very safe procedure as it doesn't involve burning tissue. For his patient with trigeminal neuralgia pain, Dr. Rosenblum plans to try a topical sphenopalatine ganglion block as the least invasive intervention before considering injecting the trigeminal nerves at the foramen, in addition to pharmacotherapy. He concludes by thanking listeners, encouraging them to check the show notes and links, mentioning institutional memberships and shadowing opportunities, and asking listeners to rate and share the podcast.

Summary In this episode of the Pain Exam Podcast, Dr. David Rosenblum provides a comprehensive review of herpes zoster and postherpetic neuralgia (PHN), focusing on pathophysiology, diagnosis, and treatment options. Dr. Rosenblum explains that postherpetic neuralgia affects approximately 25% of patients with acute herpes zoster, causing debilitating unilateral chronic pain in one or more dermatomes. He discusses the three phases of herpes zoster: acute (up to 30 days), subacute (up to 3 months), and postherpetic neuralgia (pain continuing beyond 3 months). Dr. Rosenblum identifies risk factors for developing PHN, including older age, female sex, immunosuppression, prodromal pain, severe rash, and greater acute pain severity. He details the pathophysiology involving peripheral and central sensitization, and explains different phenotypes of PHN that can guide treatment approaches. For treatment, Dr. Rosenblum reviews various options including antiviral medications (which should be started within 72 hours of onset), corticosteroids, opioids, antidepressants (particularly tricyclics and SNRIs), antiepileptics (gabapentin and pregabalin), topical agents (lidocaine and capsaicin), and interventional procedures such as epidural injections and pulsed radiofrequency. He emphasizes that prevention through vaccination with Shingrix is highly effective, with 97% effectiveness in preventing herpes zoster in patients 50-69 years old and 89% effectiveness in those over 70. Dr. Rosenblum mentions that he's currently treating a patient with trigeminal postherpetic neuralgia and is considering a topical sphenopalatine ganglion block as a minimally invasive intervention before attempting more invasive procedures. Chapters Introduction to the Pain Exam Podcast and Topic Overview Dr. David Rosenblum introduces the Pain Exam Podcast, mentioning that it covers painful disorders, alternative treatments, and practice management. He explains that this episode focuses on herpes zoster and postherpetic neuralgia as board preparation for fellows starting their programs, with ABA boards coming up in September. Dr. Rosenblum notes that he's not only preparing listeners for boards but also seeking the latest information to help treat his own patients with this notoriously difficult disease. Upcoming Conferences and Educational Opportunities Dr. Rosenblum announces several upcoming conferences including Aspen in July, Pain Week in September, and events with NYSIP and the Latin American Pain Society. He mentions he'll be teaching ultrasound and regenerative medicine at these events. Dr. Rosenblum invites listeners to sign up at nrappain.org to access a community discussing regenerative medicine, ultrasound-guided pain medicine, regional anesthesia, and board preparation. He also offers ultrasound training in New York and elsewhere, with upcoming sessions in Manhattan on July 12th and October 4th, plus private shadowing opportunities. Overview of Postherpetic Neuralgia Dr. Rosenblum defines postherpetic neuralgia as typically a unilateral chronic pain in one or more dermatomes after acute herpes zoster infection. He states that the incidence of acute herpes zoster ranges between 3-5 patients per thousand person-years, and one in four patients with acute herpes zoster-related pain will transition into postherpetic neuralgia. Dr. Rosenblum emphasizes that while this condition won't kill patients, it can be extremely debilitating and significantly reduce quality of life. Treatment Options Overview Dr. Rosenblum reviews treatment options according to the WHO pain ladder, including tricyclics like nortriptyline and antiepileptic drugs such as gabapentin. He explains that if pain is not significantly reduced, interventional treatments like epidural injections with local anesthetics and corticosteroids or pulsed radiofrequency of the dorsal root ganglion are options. For postherpetic neuralgia specifically, Dr. Rosenblum notes that preferred treatments include transdermal capsaicin, lidocaine, or oral drugs such as antidepressants or antiepileptics. Phases of Herpes Zoster and Definitions Dr. Rosenblum outlines the three phases during herpes zoster reactivation: acute herpes zoster-related pain (lasting maximum 30 days), subacute herpes zoster-related pain (pain after healing of vesicles but disappearing within 3 months), and postherpetic neuralgia (typically defined as pain continuing after 3 months). He mentions that acute herpes zoster pain often begins with prodromal pain starting a few days before the appearance of the rash. Incidence and Risk Factors Dr. Rosenblum states that the incidence of herpes zoster ranges between 3-5 patients per 1,000 person-years, with approximately 5-30% of cases leading to postherpetic neuralgia. He identifies risk factors including older age, female sex, immunosuppression, prodromal pain, severe rash, and greater acute pain severity. Dr. Rosenblum describes the clinical manifestations as a mosaic of somatosensory symptoms including burning, deep aching pain, tingling, itching, stabbing, often associated with tactile and cold allodynia. Impact on Quality of Life Dr. Rosenblum emphasizes that postherpetic neuralgia can be debilitating, impacting both physical and emotional functioning and causing decreased quality of life. He notes that it leads to fatigue, insomnia, depression, anorexia, anxiety, and emotional distress. Dr. Rosenblum stresses the importance of exploring methods for prevention of postherpetic neuralgia and optimizing pain treatment for both subacute herpes zoster-related pain and postherpetic neuralgia. Literature Review and Pathophysiology Dr. Rosenblum mentions that he's discussing a literature review from 2024 that updates previous practical guidelines published in 2011. He explains the pathophysiology of postherpetic neuralgia, which involves sensitization of peripheral and sensory nerves from damage. Dr. Rosenblum describes how inflammatory mediators reduce the stimulus threshold of nociceptors and increase responsiveness, resulting in pathological spontaneous discharges, lower thresholds for thermal and mechanical stimuli, and hyperalgesia. Central Sensitization and Nerve Damage Dr. Rosenblum explains that central sensitization results from peripheral nociceptor hyperactivity leading to plastic changes in the central nervous system, involving amplification of pain signals and reduced inhibition. He describes how nerve damage in postherpetic neuralgia patients results from neuronal death due to severe inflammatory stimuli or secondary to neuronal swelling. Dr. Rosenblum notes that motor defects occur in 0.05% of patients with herpes zoster, observed as abdominal pseudohernias or motor weakness of limbs limited to the affected myotome. Different Phenotypes and Classification Dr. Rosenblum discusses different phenotypes of postherpetic neuralgia and how phenotyping can determine treatment. He explains that there are several ways to classify the phenotypes, with one categorizing patients into three subtypes: sensory loss (most common), thermal gain, and thermal loss with mechanical gain. Dr. Rosenblum describes the mechanistic categorization, including the irritable nociceptive phenotype characterized by preserved sensation, profound dynamic mechanical allodynia, reduced pressure pain threshold, and relief with local anesthetic infiltration. Deafferentation Phenotype Dr. Rosenblum explains that a deafferentation phenotype may arise from destruction of neurons by the virus in the dorsal root ganglion. This phenotype is characterized by sensory loss, including thermal and vibratory sensation without prominent thermal allodynia. He notes that mechanical allodynia can occur secondary to A-beta fibers activating spinothalamic pathways (known as phenotypic switches), along with pressure hyperalgesia and temporal summation suggesting central sensitization. Dr. Rosenblum mentions that in one study, this phenotype was present in 10.8% of individuals, and for those with deafferentation pain, gabapentinoids, antidepressants, and neuromodulatory therapies like repetitive transcranial magnetic stimulation may be beneficial. Diagnosis and Physical Examination Dr. Rosenblum discusses the diagnosis of herpes zoster and postherpetic neuralgia, emphasizing the importance of physical examination. He explains that diagnosis is based on the rash, redness, papules, and vesicles in the painful dermatomes, with healing vesicles showing crust formation. Dr. Rosenblum notes that the rash is generally unilateral and does not cross the midline of the body. In postherpetic neuralgia patients, he mentions that scarring, hyper or hypopigmentation is often visible, with allodynia present in 45-75% of affected patients. Sensory Testing and Assessment Dr. Rosenblum explains that in patients with postherpetic neuralgia, a mosaic of somatosensory alterations can occur, manifesting as hyperalgesia, allodynia, and sensory loss. These can be quantified by quantitative sensory testing, which assesses somatosensory functions, dermal detection thresholds for perception of cold, warmth, and paradoxical heat sensations. He notes that testing can provide clues regarding underlying mechanisms of pain, impaired conditioned pain modulation, temporal summation suggesting central sensitization, and information about the type of nerve damage and surviving afferent neurons. Prevention Through Vaccination Dr. Rosenblum discusses prevention of acute herpes zoster through vaccination, noting that the risk increases with reduced immunity. He highlights studies evaluating Shingrix, a vaccine for herpes zoster, which showed 97% effectiveness in preventing herpes zoster in patients 50-69 years old with healthy immune systems and 89% effectiveness in patients over 70. Dr. Rosenblum states that Shingrix is 89-91% effective in preventing postherpetic neuralgia development in patients with healthy immune systems and 68-91% effective in those with weakened or underlying conditions. Treatment Objectives Dr. Rosenblum outlines the treatment objectives for herpes zoster and postherpetic neuralgia. For acute herpes zoster, objectives include relieving pain, reducing severity and duration of pain, accelerating recovery of epidermal defects, and preventing secondary infections. For postherpetic neuralgia, the objectives are pain alleviation and improved quality of life. Dr. Rosenblum lists available treatments including psychotherapy, opiates, antidepressants, antiepileptics, NMDA antagonists, topical agents, and interventional treatments such as epidurals, pulsed radiofrequency, nerve blocks, and spinal cord stimulation. Antiviral Medications Dr. Rosenblum emphasizes that antiviral drugs should be started within 72 hours of clinical onset, mentioning famciclovir, valacyclovir, and acyclovir. He notes there is no evidence for effectiveness after 72 hours in patients with uncomplicated herpes zoster. Dr. Rosenblum provides dosing information: for immunocompetent patients, famciclovir 500mg and valacyclovir 1000mg three times daily for seven days; for immunocompromised patients, famciclovir 1000mg three times daily for 10 days, while acyclovir should be given IV in the immunocompromised. Benefits of Antiviral Therapy Dr. Rosenblum explains that antiviral medication accelerates the disappearance of vesicles and crusts, promotes healing of skin lesions, and prevents new lesions from forming. By inhibiting viral replication, he notes that antiviral therapy likely reduces nerve damage, resulting in reduced incidence of postherpetic neuralgia, and should be started as soon as possible. Corticosteroids and Opioids Dr. Rosenblum discusses the use of corticosteroids, noting that when added to antiviral medications, they may reduce the severity of acute herpes zoster-related pain, though increased healing of skin lesions was not observed in one study. He mentions that a Cochrane review found oral corticosteroids ineffective in preventing postherpetic neuralgia. Regarding opioids, Dr. Rosenblum states they are commonly used alongside antivirals for controlling acute herpes zoster pain, with tramadol having a number needed to treat (NNT) of 4.7 and strong opioids having an NNT of 4.3 for 50% pain reduction. Methadone and Antidepressants Dr. Rosenblum discusses methadone as an NMDA receptor antagonist used in acute and chronic pain management, though he notes there are no randomized controlled trials determining its efficacy in acute herpes zoster pain or postherpetic neuralgia. He explains that methadone can modulate pain stimuli by inhibiting the uptake of norepinephrine and serotonin, resulting in decreased development of hyperalgesia and opioid tolerance, but has side effects including constipation, nausea, sedation, and QT prolongation that can trigger torsades de pointes. Dr. Rosenblum identifies antidepressants as first-line therapy for postherpetic neuralgia, including tricyclics and SNRIs, with tricyclics having an NNT of 3 and SNRIs an NNT of 6.4 for 50% pain reduction. Antiepileptics and Pharmacological Treatment Summary Dr. Rosenblum discusses antiepileptics like gabapentin and pregabalin for postherpetic neuralgia. He cites two trials measuring gabapentin's effect, concluding it was effective compared to placebo with a pooled NNT of 4.4, while pregabalin had an NNT of 4.9. Dr. Rosenblum summarizes that pharmacological treatment is well established for subacute herpes zoster pain, though new high-quality evidence has been lacking since the last update in 2011. Topical Agents Dr. Rosenblum discusses local anesthetic topical agents including lidocaine and capsaicin creams and patches. He notes that 8% capsaicin provided significant pain reduction during 2-8 weeks, while 5% lidocaine patches provided moderate pain relief after eight weeks of treatment. Dr. Rosenblum also mentions acute herpes zoster intracutaneous injections, citing a study where single intracutaneous injection with methylprednisolone combined with ropivacaine versus saline alone showed significant difference in VAS score at 1 and 4 weeks post-intervention favoring the intervention group. Intracutaneous Injections Dr. Rosenblum discusses the effect of repetitive intracutaneous injections with ropivacaine and methylprednisolone every 48 hours for one week. He cites a randomized control trial comparing antivirals plus analgesics to antivirals plus analgesics and repeat injections, finding the intervention group had significantly shorter duration of pain, lower VAS scores, and lower incidence of postherpetic neuralgia (6.4% vs 28% at 3 months). Dr. Rosenblum notes that a potential side effect of cutaneous methylprednisolone injection is fat atrophy, though this wasn't reported in the study. Summary of Local Anesthetics Dr. Rosenblum summarizes that there are no new studies reporting the efficacy of capsaicin 8% for postherpetic neuralgia, but it remains widely used in clinical practice and is approved in several countries. He notes that lidocaine patches can reduce pain intensity in patients with postherpetic neuralgia but may be more beneficial in patients with allodynia. Dr. Rosenblum adds that intracutaneous injections may be helpful for short periods, while repetitive injections with local anesthetics may reduce VAS scores for up to six months but can cause subcutaneous fat atrophy. Interventional Treatments: Epidural and Paravertebral Injections Dr. Rosenblum discusses interventional treatments, noting that previous guidelines found epidural injection with corticosteroids and local anesthetic as add-on therapy superior to standard care alone for up to one month in managing acute herpes zoster pain. He mentions a randomized controlled trial showing no difference between interlaminar and transforaminal epidural steroid injections for up to three months after the procedure.

Timing of Interventions and Continuous Epidural Blockade Dr. Rosenblum cites a retrospective study showing that transforaminal epidural injections administered for acute herpes zoster-related pain were associated with significantly shorter time to pain relief compared to those performed in the subacute phase. He also mentions a randomized controlled trial finding that continuous epidural blockade combined with opioids and gabapentin reduced NRS pain scores more than analgesic drug treatments alone during three-day follow-up, though both studies were low-quality. Interventions for Postherpetic Neuralgia Dr. Rosenblum discusses interventions specifically for postherpetic neuralgia, citing a small randomized controlled trial that demonstrated decreased NRS pain scores six months post-treatment for repeat versus single epidural steroid injections (15mg vs 5mg dexamethasone) administered over 24 days. The trial also found increased likelihood of complete remission during 6-month follow-up in the group receiving repeat epidural dexamethasone, though this was low-quality evidence. Summary of Epidural and Paravertebral Injections Dr. Rosenblum summarizes that epidural or paravertebral injections of local anesthetic and/or glucocorticoids could be considered in treating acute herpes zoster-related pain. For subacute postherpetic neuralgia pain, he notes low-quality evidence supporting epidural injections, while for postherpetic neuralgia, evidence supports continuous epidural infusion, though also of low quality. Dr. Rosenblum emphasizes that none of the included studies for postherpetic neuralgia investigating epidural or paravertebral injections resulted in decreased pain compared to standard therapy.

Ce 216e épisode de Pos. Report reçoit deux marins qui, du 14 au 22 juin, disputeront le Tour de Bretagne à la voile entre Perros-Guirec et Quiberon, Alexis Loison (Groupe Réel) et Alexis Thomas (Wings of the Ocean).Nos deux invités commencent par évoquer cette épreuve qui fête cette année sa 15e édition, avec toujours le même format, à savoir qu'elle se court en double et par étapes. Alexis Loison, qui y a participé huit fois et l'a gagnée à deux reprises, avec Fred Duthil en 2029 puis Guillaume Pirouelle il y a deux ans, explique que la clé est la régularité, tandis qu'Alexis Thomas se souvient d'une première participation, en 2021, qui s'était terminée sur un caillou de l'Aber Wrac'h.Ils expliquent ensuite le choix de leurs co-skippers respectifs, Corentin Horeau pour le Normand, Malo Wessely pour le Rochelais, qui raconte au passage comment il est venu à la voile de compétition et au Figaro en particulier, sa famille étant très proche de celle des Levaillant père et fils (Jean-Baptiste et Arthur).Nous évoquons ensuite avec eux leur début de saison, marqué par une première victoire sur le circuit Figaro lors de la Solo Guy Cotten pour Alexis Thomas, qui l'explique notamment par un budget enfin à la hauteur de ses ambitions et l'arrivée de Romen Richard comme entraîneur du pôle de La Rochelle. Et même si la Transat Paprec s'est avérée frustrante (9e avec Pauline Courtois après avoir fait une partie de la course aux avant-postes), il estime avoir trouvé quelque chose en termes de vitesse, notamment au portant.Quant à Alexis Loison, il explique comment il “jongle” entre son travail à la voilerie Incidence et les navigations, notamment sur le nouveau JPK 1050 qu'il met actuellement au point. Nous enchaînons sur leur grand objectif de la saison, la Solitaire du Figaro, la 19e d'Alexis Loison, la 5e d'Alexis Thomas. Le premier présente le parcours et revient sur quelques souvenirs marquants, entre son unique victoire d'étape à Plymouth et la première du Figaro 3, en 2019.Diffusé le 10 Juin 2025Générique : Fast and wild/EdRecordsPost-production : Grégoire LevillainHébergé par Ausha.

Welcome to the podcast with Dr. Brendan McCarthy!   This episode takes you deep into the real-world practice of prescribing testosterone therapy for women. This is not a high-level overview—this is a nuts and bolts breakdown: ✅ Who it's for ✅ How it's dosed ✅ What labs to run ✅ What delivery methods are safest ✅ Why it's often done wrong—and how to get it right   With over 20 years of clinical experience, Dr. McCarthy shares the insights no seminar or textbook can offer, including the emotional and psychological challenges women face when beginning testosterone therapy, and the very real fears around side effects and community stigma.  

Welcome to the podcast with Dr. Brendan McCarthy!   In this episode we dive deep into one of the most misunderstood and debated topics in hormone health: testosterone replacement therapy (TRT) for women. You may have heard horror stories—or glowing reviews. But what's the truth? Dr. McCarthy discusses: - Why testosterone matters for women's health - How it affects brain chemistry, mood, bone density, and even breast tissue - Its role after estrogen-suppressing breast cancer treatments - The difference between safe and unsafe TRT - What your provider should be doing to monitor and manage it effectively   Dr. Brendan McCarthy founded Protea Medical Center in 2002. While he's been the chief medical officer, Protea has grown and evolved into a dynamic medical center serving the Valley and Central Arizona. A nationally recognized as an expert in hormone replacement therapy, Dr McCarthy s the only instructor in the nation who teaches BioHRT on live patients. Physicians travel to Arizona to take his course and integrate it into their own practices. Besides hormone replacement therapy, Dr. McCarthy has spoken nationally and locally before physicians on topics such as weight loss, infertility, nutritional therapy and more.   Citations: Popma, Arne, et al.

The average person spends up to 18 hours in their home. Therefore, our homes are not just places to rest. They're also environments that significantly impact our health and well-being.Spending so much time indoors makes it important to ensure our homes have as minimal harmful chemicals in the environment as possible. Our homes are often considered our safety nests, where we seek comfort and security, but they can also harbor hidden dangers if not properly maintained.That's why we're so glad to chat on IG Live with Alexandra Destler, Founder and CEO of SafetyNEST.SafetyNEST is an award-winning digital platform committed to providing the most credible information about the effects of toxic chemicals on prenatal and early childhood health in order to safeguard children's health and reduce the incidence of preventable diseases.During this Live, we're going to discuss overlooked environmental health factors in our homes, how they impact pregnancy outcomes, resources and tools people can use, and so much more!Learn more about SafetyNEST: https://www.mysafetynest.com/Get tested for BPA, phthalates, parabens, and other hormone-disrupting chemicals with Million Marker's Detect & Detox Test Kit: https://www.millionmarker.com/

Nonunion following naviculocuneiform (NC) joint arthrodesis is a well-recognized complication. Most studies reporting nonunion rates involve a limited number of cases or focus on a single disease entity. Moreover, there is variation between studies with regard to the number of articular facets included in the arthrodesis as well as the fixation construct used, with no clear evidence indicating how these factors influence union. This study, using the largest cohort to date, aims to investigate the nonunion rate following NC joint arthrodesis and to identify demographic and surgical factors associated with nonunion.   In conclusion, this study demonstrates a significant rate of nonunion following NC joint arthrodesis, exceeding that previously reported. We found that the rate of nonunion significantly increased in arthrodeses involving only the medial NC facet as compared to those including multiple NC facets.     Click here to read the article.

Les accidents vasculaires cérébraux (AVC) constituent une préoccupation majeure en santé publique, avec plus de 120 000 cas recensés chaque année en France, entraînant environ 30 000 décès. Traditionnellement associés aux personnes âgées, les AVC touchent également des populations plus jeunes, une tendance mise en lumière par des études récentes.​Incidence des AVC selon l'âgeSelon le bulletin épidémiologique publié le 4 mars 2025 par Santé publique France, l'âge moyen des patients hospitalisés pour un AVC en 2022 était de 73,2 ans, avec une différence notable entre les sexes : 70,5 ans pour les hommes et 76,3 ans pour les femmes. La moitié des patients avaient plus de 75 ans au moment de l'AVC, et 25,4 % étaient âgés de moins de 65 ans. Ces chiffres illustrent que, bien que l'incidence des AVC augmente avec l'âge, une proportion significative touche des individus de moins de 65 ans. ​Le risque d'AVC augmente significativement avec l'âge, atteignant son maximum chez les personnes de 85 ans et plus. Augmentation des AVC chez les moins de 65 ansBien que le vieillissement de la population explique en partie l'augmentation globale des AVC, un "signal épidémiologique" préoccupant est observé chez les adultes de moins de 65 ans depuis une quinzaine d'années. Cette tendance suggère une hausse de l'incidence et des hospitalisations pour AVC dans cette tranche d'âge, nécessitant une attention particulière. ​Facteurs de risque chez les moins de 65 ansPlusieurs facteurs peuvent contribuer à cette augmentation chez les moins de 65 ans :​Hypertension artérielle : facteur de risque majeur d'AVC.​Diabète : augmente le risque de maladies vasculaires, y compris les AVC.​Tabagisme : endommage les vaisseaux sanguins et favorise les caillots.​Sédentarité et obésité : contribuent à l'hypertension et au diabète.​Consommation excessive d'alcool : peut entraîner une hypertension et des troubles du rythme cardiaque.​L'adoption de modes de vie sains, incluant une alimentation équilibrée, une activité physique régulière et l'arrêt du tabac, est essentielle pour réduire ces risques.​ConclusionBien que le risque d'AVC augmente avec l'âge, touchant principalement les personnes de plus de 75 ans, une proportion notable survient chez les moins de 65 ans. L'augmentation de l'incidence dans cette tranche d'âge souligne l'importance de la prévention et de la sensibilisation aux facteurs de risque modifiables, afin de réduire l'impact des AVC sur cette population.

In this episode of the Movement Logic Podcast, hosts Laurel Beversdorf and Dr. Sarah Court critically examine common beliefs surrounding spinal flexion exercises and osteoporosis, particularly from a yoga and Pilates perspective. They delve into two pivotal studies on exercise and fracture risk, both led by Dr. Mehrsheed Sinaki, a renowned specialist in physical medicine and rehabilitation at the Mayo Clinic in Rochester, Minnesota.The first study, Postmenopausal Spinal Osteoporosis: Flexion versus Extension Exercises, is frequently cited on Pilates websites and in yoga and Pilates teacher trainings as evidence that spinal flexion is risky for individuals with osteoporosis—even during bodyweight exercises. However, despite its widespread use to justify movement restrictions, the study has notable methodological flaws. The second study, Stronger Back Muscles Reduce the Incidence of Vertebral Fractures: A Prospective 10-Year Follow-up of Postmenopausal Women, suggests that progressively overloaded back strengthening exercises can reduce fracture risk—even if the strengthening occurred only for a few years in the distant past. Yet, this study also has its own limitations.When viewed together, these studies present an intriguing contrast: one warns of the potential dangers of spinal flexion (even under low loads) based on weak evidence, while the other highlights the lasting protective benefits of strength training. Laurel and Sarah explore why bodyweight spinal flexion is often singled out as risky and question whether this caution is always justified.They also discuss the ethical implications and the boundaries of a movement teacher's scope of practice—particularly when making broad recommendations to avoid certain movements based on limited or flawed research. The hosts emphasize the importance of individualized context in exercise prescriptions, the need to follow medical guidance from a student's doctor, the evidence-backed benefits of strength training, and the necessity of empowering students with the autonomy to make informed movement choices.Get on the wait list for our Bone Density Course: Lift for LongevityFollow Movement Logic on Instagram00:56 Podcast Production & Content Creation01:33 Bone Density & Squat Depth02:20 Benefits of Full ROM Strength Training08:24 Is Spinal Flexion Dangerous for OP?10:00 Issues with Yoga/Pilates for OP Classes18:43 1984 Paper: Flexion vs. Extension for OP40:22 Flaws in the 1984 Study41:57 2002 Study: Stronger Back Muscles & Fractures43:03 2002 Study Design & Methods46:35 2002 Study Key Findings52:09 2002 Study Limitations56:30 Practical Takeaways01:06:15 Ethics for Movement Teachers01:17:43 ConclusionReferences:Episode 77: Make Dr. Loren Fishman Make SenseEpisode 92: Are You Getting Dexa Scammed? 1984 Sinaki paper 2002 Sinaki paper

Host Dr. Davide Soldato and his guests Dr. Ann Wu and Dr. Alexa White discuss the article "Air Pollution and Breast Cancer Incidence in the Multiethnic Cohort Study" and the editorial "Growing Evidence for the Role of Air Pollution in Breast Cancer Development"  TRANSCRIPT The guests on this podcast episode have no disclosures to declare.  Dr. Davide Soldato: Hello and welcome to JCO After Hours, the podcast where we sit down with authors from some of the latest articles published in the Journal of Clinical Oncology. I am your host, Dr. Davide Soldato, Medical Oncologist at Ospedale San Martino in Genoa, Italy.  Today, we are joined by JCO authors Dr. Anna Wu and Dr. Alexander White. Dr. Wu is a professor of Population and Public Health Sciences at the Keck School of Medicine of UCS, while Dr. White is an investigator in the Epidemiology branch of the Environment and Cancer Epidemiology Group at the National Institute of Health.  Today, we will be discussing the article titled, “Air Pollution and Breast Cancer Incidence in the Multiethnic Cohort Study,” and the accompanying editorial.  So, thank you for speaking with us, Dr. Wu, Dr. White. Dr. Anna Wu: Thank you for having us. Dr. Alexandra White: Yes, thank you so much for the invitation to be here. Dr. Davide Soldato: So before going in depth about the results of the study that was published in the JCO, I was wondering if you could give us like a brief introduction and a little bit of background about what was known about air pollution as a risk factor for breast cancer and what was the evidence before this study was conducted. Dr. Alexandra White: Okay. I can start with that question. So, there's been research for decades looking at the relationship between air pollution and breast cancer. And it's been a really challenging question to address for a number of reasons. One being that it can be really difficult to assess exposure to air pollution and many previous studies have had really limited information on people's residences over time. But in general, what we thought leading up to this study was that evidence was most consistent that exposure to traffic related pollutants such as nitrogen dioxide was more consistently related to a higher risk of breast cancer. The evidence for fine particulate matter or PM2.5 was less consistent. More recently, there have been a few large, well conducted studies that have supported a positive association. This new study in the multiethnic cohort led by Dr. Wu is really important because it really demonstrated that, in this large study of over 50,000 women in California, that they also do see an association with PM2.5.  Dr. Davide Soldato: Thank you very much for the introduction. So, Dr. Wu, we just want to hear a little bit more about the results. So, what was the association that was observed for PM2.5? And specifically, the study that you ran was focused on a very diverse population, a multiethnic cohort, and so I was wondering if you observed any type of differences when you consider the different populations that were included in your study. And if you could also give us a little bit of what was the composition of the women that were enrolled in this cohort. Dr. Anna Wu: Thank you for the question. So, the multiethnic cohort study is a cohort of over 200,000 individuals who were enrolled when they lived in Hawaii or California. For the air pollution studies that we've been conducting, we have focused on primarily the California participants. And in this instance for the breast cancer study, it was based on roughly 56,000 individuals out of- there were about 100,000 because half of them were men and they were not included. Of the California participants, 75% of them were African Americans or Latinos and they were self-identified as these racial ethnic groups when they enrolled in the study. And this was a particularly important consideration for us because in most of the studies that have been published so far on-air pollution and breast cancer, as well as other cancer sites, most of those studies were conducted among whites in the US or whites in Europe. And even if they included non-white populations, the numbers tend to be small so that they were not able to conduct racial ethnic specific analysis. So, we were particularly interested in examining these other racial ethnic groups because we know from other studies that racial ethnic minority groups tend to live in communities of low socioeconomic status and those communities also tend to have higher levels of various types of environmental pollutants. And so, it was important for us to actually try to tease apart these various interrelated factors.  So, what we found was that per 10 micrograms per cubic meter, we had a 28% increased risk overall in all participants combined that meet across the racial ethnic groups. We actually did not see any differences or significant differences in the hazard ratios by race ethnicity and they were in general quite compatible with each other. But we did see a stronger finding among the white participants in our study. Dr. Davide Soldato: Thank you, a lot, Dr. Wu. So, I think it's very interesting the fact that in the end you observed that air pollution is a significant risk factor across all the ethnicities that were included in the study. But I think that one very strong point of the manuscript and one very strong point of the analysis was that in the end you also corrected for a series of different factors because we know that the incidence of breast cancer can be modified, for example, by familial history or BMI or smoking habits or also alcohol consumption. And a lot of these risk factors were included in your analysis. And so, I was wondering if you could tell us a little bit whether you observed any significant differences when you observed or included also these risk factors in your analysis, or whether the association for air pollution as a risk factor stands even when we consider all of these other elements. Dr. Anna Wu: Yes. So, we considered all the well-established breast cancer risk factors. And in this situation, we were particularly interested in considering smoking, alcohol intake, use of menopausal hormones, history of diabetes, body mass index, family history, as well as physical activity, because many of these risk factors, such as, for example, diabetes and body mass index, they are risk factors for breast cancer, and air pollution, have also been found to increase risk of these factors.  So, in our analysis, we first adjusted for all of these potential confounders in a mutually adjusted manner, so all of them were considered. In addition, we also conducted stratify analysis. So as an example, we stratified the analysis to examine whether the hazard ratio associated with PM2.5 provided comparable risk estimate or hazard ratio estimates for never smokers, former smokers, and current smokers. Although we did not see significant heterogeneity by these various subgroups, we did see a significantly stronger effect of PM2.5 among individuals who did not have a family history of breast cancer.  Interestingly, our finding was also stronger among individuals who were never smokers and light alcohol drinkers, even though the results were not significantly different. So, we surmised that maybe individuals who already had a high risk because of other established risk factors for breast cancer, we were less likely to be able to observe the effect of air pollution. But it's important to note that other studies, such as the ones that Dr. White has conducted, have also looked at various subgroups, and I think part of the limitation that all of us have is that once you subdivide the study population, even if you start out with a large sample size, often the sample size gets cut in half or a third. And so, we still lack the statistical power to be able to observe significant differences. But I think it is important to note that, in fact, the hazard ratio estimates are actually quite comparable, but we did see a hint of stronger effects among never smokers, and people who were light alcohol drinkers. So, I think this is an area that we certainly need to continue to investigate since there are other subgroups, such as menopausal status, such as hormone receptor status of breast cancer, that we need to consider in future studies. There's still a lot of work we need to do to sort this out, to actually figure out who are the women who are the most susceptible to the exposures. Dr. Davide Soldato: Dr. White, I would really love a comment from you on this specific area and specifically on what still needs to be done. And related to this, a question actually, for both of you, because I think that from a methodological point of view, there is a lot of work that goes into deciding how we are going to assess the exposure to air pollution. So which type of data are we going to use? Which type of data are we currently using in the epidemiological studies that have been conducted and in the one that we are discussing right now in JCO? And what are the caveats for this data that we are using? Meaning, I think that we use mostly residential addresses, which means that we are looking at the exposure where people actually live, which might not be the place where they spend most of their time. For example, if someone is working, maybe they could be more exposed and have higher exposure when they are at work compared to when they are at home. So, I was wondering if you could give us a little bit of an overview as to what is the methodological standard of care right now in terms of this analysis and what can we do better to refine and understand this specific factor as Dr. Wu was mentioning? Dr. Alexandra White: Yeah, so I'm happy to take a first stab at that question. So, I think it's important to note just how far we've come. I think even a few years ago, air pollution was really not considered a risk factor for breast cancer. And a lot of the work that we've been doing and others have really moved this forward in terms of understanding this as a risk factor. And as I mentioned earlier, there have been a lot of challenges in exposure assessment. And to get to your question, I think that our studies in general are doing better at looking at exposure over more years, residences, more time. We know that cancer takes time to develop, and we can't rely on just a single snapshot of exposure. But as you mentioned, almost all of the studies published have really exclusively focused on residential estimates of exposure. And so, there's a real need to understand the exposures that people are experiencing in other aspects of their life, from their commute to their jobs, to really capture that totality of exposure.  And then I think one of the points that Dr. Wu was alluding to as well as we know that breast cancer is a very heterogeneous disease, so risk factors for breast cancer vary by tumor subtypes, by menopausal status at diagnosis. And a lot of studies have really focused on considering breast cancer as a combined outcome, and that might be missing some really important signals where we might have a stronger effect for certain subtypes due to the fact that there's different biologic pathways that are underlying these subtypes or by menopausal status. And so having large study populations where, as we discussed earlier, would really give us the power to look among these smaller groups of women who might be more susceptible and those with younger women, we know that incidence of cancer is rising in young people, and we need to understand the risk factors for that. And most of our studies are really focused on older individuals, so I think that's one important gap, as well as having the power to really look at different differences by tumor subtypes. Dr. Davide Soldato: I think it's very interesting, and I think one point both of you made in the original article and in the accompanying editorial is also the fact that we tend to look at these risk factors in people who are actually aged, while we maybe should be looking at this in an earlier phase of development and potentially during puberty. Do you think that we should design studies that are more focused on this population even though I think that they will take a lot of time to produce significant results?  Dr. Alexandra White: Yeah. I think that it is really important to consider how exposure during early life is related to breast cancer risk. We know that exposures during pregnancy or even as early as during puberty might be particularly relevant for breast cancer. And I think a lot of our studies have really been up against the challenge of the fact that exposure monitoring for air pollution really didn't start until the 1990s. And so, it's challenging, especially for these older cohorts, to get back at that time period that might be relevant. But I think that's something that definitely newer cohorts are going to be able to address, and I think it's going to be really important, and also will give us some clues to better understand the important windows of exposure, but also that might provide clues for the biologic pathways as well that are relevant. Dr. Davide Soldato: And just a related question, because I'm not aware of this, but are there right now cohorts that are specifically looking at this in the US or in other parts of the world? If you are aware of that, of course.  Dr. Alexandra White: There have been some cohorts that have focused on exposure during these hypothesized windows of susceptibility, but I don't think they've been able to follow those women long enough to develop breast cancer. One of the things that we're working on in the sister study is trying to expand our assessment of air pollution exposure back in time to try to get at these earlier windows of exposure. So, I'm hoping that it's something we'll be able to comment on and at least for some of the women in our cohort who are younger. But I don't know, Dr. Wu, if you're familiar with any other populations that are doing this now?  Dr. Anna Wu: Well, NCI funded several new cohorts in the last couple years that are really focused on trying to get a much more refined exposure assessment. So, I know colleagues at University of Michigan that are peers and also Dr. Wei Zheng at Vanderbilt, they are putting together newer cohorts that are younger and also trying to include a range of exposure, not just air pollution, but really environmental exposures. Those cohorts I think have the potential in the future to try to address some of these questions, but again, it will take at least another number of years before there are a sufficient number of endpoints so that they can actually do these types of studies.  Another possibility is that there are a number of big cohort studies in Asia. The age of diagnosis tends to be earlier in Asia. I know that investigators in China are very interested and concerned with the air pollution effects in China. I think there are potentials that in other countries where the age of breast cancer diagnosis is actually younger than in the US and if they establish in a manner that allows them to assess air pollution that they may have opportunities.  And I think the other way to try to address this question, whether there are studies where you can actually tap into either biomarkers or pathology samples so you won't be actually studying air pollution in a large population, but you're actually narrowing it down to try to see if you see any signals in a way that would give you some additional clues and insights as to the mechanism. So I think we're going to have to piece together various types of study to try to answer the questions because one type of study like these observational air pollution studies, will allow us to address one slice of the questions that we have and then we need to put together other studies so that we can address other aspects that we're interested in to put it together. Dr. Davide Soldato: Thank you very much both of you. That was very interesting.  Coming back to the results of the manuscript, we really focused up until now on PM2.5. But it's true that inside of the study you evaluated different pollutants. So, I was wondering whether you saw a similar association for other pollutants that were included in the study or whether the association for higher risk was observed only for PM2.5. Dr. Anna Wu: The results for NO2, NOx, PM10, and carbon monoxide were actually very compatible with the risk estimates that other studies have published as well as from the meta-analysis. So, I would say that our results from the other pollutants are actually very consistent with other results. I think one difference is that our PM2.5 estimates were based on the satellite-based PM2.5 estimates, whereas all the other pollutants were based on monitoring station estimates from EPA sponsored air monitoring stations. So, they are not measured in the same way. And I think different studies over time have used either monitoring station type measures for other pollutants. And I think we were particularly interested in PM2.5 because the measurement of PM2.5 in the monitoring world didn't start until around 2000. So, studies up until that time were less able to actually provide the assessment of PM2.5 as good as we can for air pollution. There's always misclassification. So, I think it's a matter of how much misclassification in the assessment. But, again, we are really limited in really just having exposure over one part of adult life.  Dr. Davide Soldato: Thank you very much. And one potentially related question. We are speaking in general about air pollution, but I think that since we are considering residential addresses, probably we are capturing more either traffic pollution or pollution that comes from probably industries or stuff like that, which is mostly related to residential areas or the place where people live. But I think that in the end we also think about air pollution as something that can come from different forms. And one very interesting point, Dr. White, that you made in your editorial is also that there is a global change also in the way we are faced with air pollution. For example, you made the example of wildfires in your editorial and how this might potentially change exposure to air pollution, maybe for limited times, but with concentrations that are fairly higher compared to what we generally observed. So, I was wondering if you could comment a little bit on that and also, if there is potentially a way to also consider this in future epidemiological studies. Dr. Alexandra White: Yeah, so when we talk about exposure to fine particulate matter, PM2.5, we're assessing exposure to particles that are based on the size of the particle, and we're really not evaluating the types of particles that people are experiencing exposure to. And we know that, in general, that PM2.5 composition really varies geographically due to differing sources of exposure. So, like you were saying, there might be a stronger contribution to industry or from agriculture or from traffic. And so that could really change the PM2.5 exposure profile that individuals experience. And so it could be that this is another really important area that this research needs to consider, which could really help us identify what sources of exposure are most relevant.   Wildfires are a really important growing concern. We know that wildfires are increasing in both intensity and duration and frequency, and we really don't understand the long-term health impacts of wildfires. But we know that wildfire associated PM2.5 might be one of the most dominant contributors to PM2.5 moving forward. And although we've seen historic declines in PM2.5 in the US after the Clean Air Act, those declines have really stalled. PM2.5 itself is projected to increase over the next few decades, so understanding different PM2.5 composition profiles and the sources that drive them can really help us identify the most important targets for any potential interventions. And wildfire PM2.5 in particular may be of concern because it's a combustion byproduct, and so it's thought to have more of the components that might, we hypothesize, are most relevant for breast cancer, such as PAHs or polycyclic aromatic hydrocarbons or metals. And so, these components are thought to act as endocrine disruptors, which may be particularly relevant for breast cancer. So, I think understanding this changing landscape of PM2.5 moving forward is going to be really important in understanding how PM2.5 contributes to cancers beyond just breast, but as well as other female hormone driven cancers and all of the cancers really.  Dr. Davide Soldato: Thank you very much. So, one closing remark, because I think that in general, we have been really in a field of primary prevention for breast cancer where we were focusing on individual behaviors, for example, smoking cessation, reduction in alcohol intake, reduction of BMI, increase of physical activity. But I think that the evidence that is accumulating in the last three years or so is telling us more and more that we also need to shift the perspective on prevention going not only on individuals, but also as including environmental risk. So, I was wondering, how can we include this new evidence in the policies that we implement and how policymakers should act on the data that we have available right now? Dr. Anna Wu: I think it's really important that this new information is communicated to all the stakeholders, including our policymakers, so that they are, first of all, really aware that any changes and not actually adhering to current guidelines can have long lasting consequences, deleterious consequences. And I think it's important to also note that over 90% of the world actually live in areas where PM2.5 exceeds the limit. We have observed increases in breast cancer in many middle- and low-income countries, so I think it's particularly important to emphasize that this is really not just a western country issue, it is really a global issue. Dr. Alexandra White: I agree. And I would just add to that that air pollution is not something that an individual can really change on their own. There are things you can do, you can monitor air quality, you can try to live in a home that's far away from traffic. But really these are large scale problems that really require large scale solutions. And we know that policy changes can be effective here and that this is something that, in my opinion, is not something that we leave to the individual to change. This is something that we as a society should encourage change for the health of everyone. Dr. Davide Soldato: So, thank you very much again, Dr. Wu, Dr. White, for joining us today on the podcast.

Steal can be caused by multiple factors—arterial occlusive disease proximal or distal to the AV anastomosis, high flow through the fistula at the expense of distal arterial perfusion, and failure of the distal arterial networks to adapt to this decreased blood flow.  Incidence and Risk Factors The frequency of steal syndrome is 1.6-9%1,2, depending on the vessels and conduit choice Steal syndrome is more common with brachial and axillary artery-based accesses and nonautogenous conduits. Other risk factors for steal syndrome are peripheral vascular disease, coronary artery disease, diabetes, advanced age, female sex, larger outflow conduit, multiple prior permanent access procedures, and prior episodes of steal.3,4  Long-standing insulin-dependent diabetes causes both medial calcinosis and peripheral neuropathy, which limits arteries' ability to vasodilate and adjust to decreased blood flow. Patient Presentation, Symptoms, Grading Steal syndrome is diagnosed clinically.  Symptoms after AVG creation occurs within the first few days, since flow in prosthetic grafts tend to reach a maximum value very early after creation. Native AVFs take time to mature and flow will slowly increase overtime, leading to more insidious onset of symptoms that can take months or years. The patient should have a unilateral complaint in the extremity with the AV access. Symptoms of steal syndrome, in order of increasing severity, include nail changes, occasional tingling, extremity coolness, numbness in fingertips and hands, muscle weakness, rest pain, sensory and motor deficits, fingertip ulcerations, and tissue loss.  There could be a weakened radial pulse or weak Doppler signal on the affected side, and these will become stronger after compression of the AV outflow. Symptoms are graded on a scale specified by Society of Vascular Surgery (SVS) reporting standards:5  Workup Duplex ultrasound can be used to analyze flow volumes. A high flow volume (in autogenous accesses greater than 800 mL/min, in nonautogenous accesses greater than 1200 mL/min) signifies an outflow issue. The vein or graft is acting as a pressure sink and stealing blood from the distal artery. A low flow volume signifies an inflow issue, meaning that there is a proximal arterial lesion preventing blood from reaching the distal artery. Upper extremity angiogram can identify proximal arterial lesions. Prevention Create the AV access as distal as possible, in order to preserve arterial inflow to the hand and reduce the anastomosis size and outflow diameter.  SVS guidelines recommend a 4-6mm arteriotomy diameter to balance the need for sufficient access flow with the risk of steal. If a graft is necessary, tapered prosthetic grafts are sometimes used in patients with steal risk factors, using the smaller end of the graft placed at the arterial anastomosis, although this has not yet been proven to reduce the incidence of steal.  Indications for Treatment Intervention is recommended in lifestyle-limiting cases of Grade II and all Grade III steal cases. If left untreated, the natural history of steal syndrome can result in chronic limb ischemia, causing gangrene with loss of digits or limbs. Treatment Options Conservative management relies on observation and monitoring, as mild cases of steal syndrome may resolve spontaneously. Inflow stenosis can be treated with endovascular intervention (angioplasty with or without stent) Ligation is the simplest surgical treatment, and it results in loss of the AV access. This is preferred in patients with repetitive failed salvage attempts, venous hypertension, and poor prognoses. Flow limiting procedures can address high volumes through the AV access. Banding can be performed with surgical cutdown and placement of polypropylene sutures or a Dacron patch around the vein or graft. The Minimally Invasive Limited Ligation Endoluminal-Assisted Revision (MILLER) technique employs a percutaneous endoluminal balloon inflated at the AVF to ensure consistency in diameter while banding Plication is when a side-biting running stitch is used to narrow lumen of the vein near the anastomosis. A downside of flow-limiting procedures is that it is often difficult to determine how much to narrow the AV access, as these procedures carry a risk of outflow thrombosis. There are also surgical treatments focused on reroute arterial inflow. The distal revascularization and interval ligation (DRIL) procedure involves creation of a new bypass connecting arterial segments proximal and distal to the AV anastomosis, with ligation of the native artery between the AV anastomosis and the distal anastomosis of the bypass. Reversed saphenous vein with a diameter greater than 3mm is the preferred conduit. Arm vein or prosthetic grafts can be used if needed, but prosthetic material carries higher risk of thrombosis. The new arterial bypass creates a low resistance pathway that increases flow to distal arterial beds, and interval arterial ligation eliminates retrograde flow through the distal artery.  The major risk of this procedure is bypass thrombosis, which results in loss of native arterial flow and hand ischemia. Other drawbacks of DRIL include procedural difficulty with smaller arterial anastomoses, sacrifice of saphenous or arm veins, and decreased fistula flow. Another possible revision surgery is revision using distal inflow (RUDI). This procedure involves ligation of the fistula at the anastomosis and use of a conduit to connect the outflow vein to a distal artery. The selected distal artery can be the proximal radial or ulnar artery, depending on the preoperative duplex. The more dominant vessel should be spared, allowing for distal arterial beds to have uninterrupted antegrade perfusion. The nondominant vessel is used as distal inflow for the AV access. RUDI increases access length and decreases access diameter, resulting in increased resistance and lower flow volume through the fistula. Unlike DRIL, RUDI preserves native arterial flow.  Thrombosis of the conduit would put the fistula at risk, rather than the native artery.  The last surgical revision procedure for steal is proximalization of arterial inflow (PAI). In this procedure, the vein is ligated distal to the original anastomosis site and flow is re-established through the fistula with a PTFE interposition graft anastomosed end-to-side with the more proximal axillary artery and end-to-end with the distal vein. Similar to RUDI, PAI increases the length and decreases the diameter of the outflow conduit. Since the axillary artery has a larger diameter than the brachial artery, there is a less significant pressure drop across the arterial anastomosis site and less steal. PAI allows for preservation of native artery's continuity and does not require vein harvest.  Difficulties with PAI arise when deciding the length of the interposition graft to balance AV flow with distal arterial flow. 2. Ischemic Monomelic Neuropathy Definition Ischemic monomelic neuropathy (IMN) is a rare but serious form of steal that involves nerve ischemia. Severe sensorimotor dysfunction is experienced immediately after AV access creation. Etiology IMN affects blood flow to the nerves, but not the skin or muscles because peripheral nerve fibers are more vulnerable to ischemia. Incidence and Risk Factors IMN is very rare; it has an estimated incidence of 0.1-0.5% of AV access creations.6 IMN has only been reported in brachial artery-based accesses, since the brachial artery is the sole arterial inflow for distal arteries feeding all forearm nerves. IMN is associated with diabetes, peripheral vascular disease, and preexisting peripheral neuropathy that is associated with either of the conditions. Patient Presentation Symptoms usually present rapidly, within minutes to hours after AV access creation. The most common presenting symptom is severe, constant, and deep burning pain of the distal forearm and hand. Patients also report impairment of all sensation, weakness, and hand paralysis. Diagnosis of IMN can be delayed due to misattribution of symptoms to anesthetic blockade, postoperative pain, preexisting neuropathy, a heavily bandaged arm precluding neurologic examination. Treatment Treatment is immediate ligation of the AV access. Delay in treatment will quickly result in permanent sensorimotor loss.   3. Perigraft Seroma Definition A perigraft seroma is a sterile fluid collection surrounding a vascular prosthesis and is enclosed within a pseudomembrane. Etiology and Incidence Possible etiologies include: transudative movement of fluid through the graft material, serous fluid collection from traumatized connective tissues (especially the from higher adipose tissue content in the upper arm), inhibition of fibroblast growth with associated failure of the tissue to incorporate the graft, graft “wetting” or kinking during initial operation, increased flow rates, decreased hematocrit causing oncotic pressure difference, or allergy to graft material. Seromas most commonly form at anastomosis sites in the early postoperative period. Overall seroma incidence rates after AV graft placement range from 1.7–4% and are more common in grafts placed in the upper arm (compared to the forearm) and Dacron grafts (compared to PTFE grafts).7-9 Patient Presentation and Workup Physical exam can show a subcutaneous raised palpable fluid mass Seromas can be seen with ultrasound, but it is difficult to differentiate between the types of fluid around the graft (seroma vs. hematoma vs. abscess) Indications for Treatment Seromas can lead to wound dehiscence, pressure necrosis and erosion through skin, and loss of available puncture area for hemodialysis Persistent seromas can also serve as a nidus for infection. The Kidney Disease Outcomes Quality Initiative (KDOQI) guidelines10 recommend a tailored approach to seroma management, with more aggressive surgical interventions being necessary for persistent, infected-appearing, or late-developing seromas.   Treatment The majority of early postoperative seromas are self-limited and tend to resolve on their own Persistent seromas have been treated using a variety of  methods-- incision and evacuation of seroma, complete excision and replacement of the entire graft, and primary bypass of the involved graft segment only. Graft replacement with new material and rerouting through a different tissue plane has a higher reported cure rate and lower rate of infection than aspiration alone.9     4. Infection Incidence and Etiology The reported incidence of infection ranges 4-20% in AVG, which is significantly higher than the rate of infection of 0.56-5% in AVF.11  Infection can occur at the time of access creation (earliest presentation), after cannulation for dialysis (later infection), or secondary to another infectious source. Infection can also further complicate a pre-existing access site issue such as infection of a hematoma, thrombosed pseudoaneurysm, or seroma. Skin flora from frequent dialysis cannulations result in common pathogens being Staphylococcus, Pseudomonas, or polymicrobial species. Staphylococcus and Pseudomonas are highly virulent and likely to cause anastomotic disruption. Patient Presentation and Workup Physical exam will reveal warmth, pain, swelling, erythema, induration, drainage, or pus. Occasionally, patients have nonspecific manifestations of fever or leukocytosis. Ultrasound can be used to screen for and determine the extent of graft involvement by the infection.   Treatments In AV fistulas: Localized infection can usually be managed with broad spectrum antibiotics.  If there are bleeding concerns or infection is seen near the anastomosis site, the fistula should be ligated and re-created in a clean field. In AV grafts: If infection is localized, partial graft excision is acceptable. Total graft excision is recommended if the infection is present throughout the entire graft, involves the anastomoses, occludes the access, or contains particularly virulent organisms Total graft excision may also be indicated if a patient develops recurrent bacteremia with no other infectious source identified. For graft excision, the venous end of the graft is removed and the vein is oversewn or ligated. If the arterial anastomosis is intact, a small cuff of the graft can be left behind and oversewn. If the arterial anastomosis is involved, the arterial wall must be debrided and ligation, reconstruction with autogenous patch angioplasty, or arterial bypass can be pursued. References   1.
