Welcome to the Hot Topics podcast from NB Medical with Dr Neal Tucker. While everyone tries to unpick the new NHS 10-year plan, we focus on the here and now with three new pieces of research.We kick off with two gems in the BJGP - first, examining whether anti-depressants actually help with insomnia, and second, whether anti-depressants cause postural hypotension in older people, and which may be the worst. Finally, we look at a good news story, with data publishing on a new treatment for cancers linked to mismatch repair genes.ReferencesBJGP Insomnia paperBJGP Anti-Ds and postural hypotension paperNEJM dMMR gene cancer therapy www.nbmedical.com/podcast

Today, Dr. Monica Gray, Dr. Pradip Kamat, and Dr. Rahul Damania discuss two real-life pediatric cases of hyponatremia in the PICU. They talk through a case of a six-month-old baby with severe sodium depletion and a teenager dealing with cancer-related hyponatremia. The team breaks down the pathophysiology, walks us through the diagnostic workups, and discusses the careful management needed for these cases. They emphasize the importance of correcting sodium levels gradually and addressing the root cause of the problem. They share practical tips for intensivists and highlight why staying vigilant and following evidence-based care is so crucial when managing critically ill kids with electrolyte disturbances.

Show notes at pharmacyjoe.com/episode1037. In this episode, I'll discuss whether there is an association between the sedative dose and postintubation hypotension and rapid sequence intubation. The post 1037: Hypotension After Intubation – Is It the Sedative Dose That Matters? appeared first on Pharmacy Joe.

Recently, sophisticated myelographic techniques to precisely subtype and localize CSF leaks have been developed and refined. These techniques improve the detection of various types of CSF leaks thereby enabling targeted therapies. In this episode, Katie Grouse, MD, FAAN, speaks with Ajay A. Madhavan, MD, author of the article “Radiographic Evaluation of Spontaneous Intracranial Hypotension” in the Continuum® June 2025 Disorders of CSF Dynamics issue. Dr. Grouse is a Continuum® Audio interviewer and a clinical assistant professor at the University of California San Francisco in San Francisco, California. Dr. Madhavan is assistant professor of radiology at the Mayo Clinic in Rochester, Minnesota.

Dr Grouse:  This is Dr Katie Grouse. Today I'm interviewing Dr Ajay Madhavan about his article on Radiographic Evaluation of Spontaneous Intracranial Hypotension, which he wrote with Dr Levi Chazen. This article appears in the June 2025 Continuum issue on disorders of CSF dynamics. Welcome to the podcast, and please introduce yourself to our audience. Dr Madhavan:  Hi, thanks a lot, Katie. Yeah, so I'm Ajay Madhaven. I'm a neuroradiologist at the Mayo Clinic in Rochester, Minnesota. I did all my training here, so, I've been here for a long time. And I have a lot of interest in spinal CSF leaks, and I do a lot of that work. And so I'm really excited to be talking about this article with you. Dr Grouse:  I'm really excited too. And in fact, it's such a pleasure to have you here talking today on this topic. I know a lot's changed in this field, and I'm sure many of our listeners are really interested in learning about the developments and imaging techniques to improve detection and treatment of CSF leaks, especially since maybe we've learned about this in training. I want to start by asking you what you think is the most important takeaway from your article. Dr Madhavan:  Yeah, that's a great question. I think---and you kind of already alluded to it---I think the main thing is, I hope people recognize that this field has really changed a lot in the last five to ten years, through a lot of multi-institutional collaboration and also collaboration between different specialties. We've learned a lot about different types of spinal CSF leaks, how we can recognize the disease, particularly the types of myelography that we need to be using to accurately localize and treat these leaks. Those are the things that have really evolved in the last five to ten years, and they've really helped us improve these patients' lives. Dr Grouse:  Can you remind us of the different common types of spinal leaks that can cause spontaneous intracranial hypotension? Dr Madhavan:  Yeah, so there are a number of different spinal CSF leaks, types, and I would say the three most common ones that really most people should try to be aware of and cognizant of are: first, ventral dural tears. So those are, like, just physical holes in the dura. And they're usually caused by little bone spurs that come from the vertebral columns. So, they're often patients who have some degenerative changes in their spine. And those are really very common. Another type of spinal CSF leak that we commonly see is a lateral dural tear. So that's like the same thing in a slightly different location. So instead of being in the front, it's off to the side of the dura laterally. And so, it's also just a hole in the dura. And then the third and most recently discovered type of spinal CSF leak is a CSF-venous fistula. So those are direct connections between the subarachnoid space and little paraspinal vein. And it took us a long time to even realize that this was a real pathology. But now that it's been recognized, we've found that this is actually quite common. So those three types of leaks are probably the three most common that we see. And there's certainly others out there, but I would say over 90% of them fall into one of those three categories. Dr Grouse:  That's a great review, thank you. Just as another quick review, as we talk more about this topic, can you remind us of some of the most common or typical brain imaging findings that you'll see in cases of spontaneous intracranial hypotension? Dr Madhavan:  Yeah, absolutely. So, when you do a brain MRI in a patient who has spontaneous intracranial hypotension, you will usually, though not always, see typical brain MRI abnormalities. And I kind of think of those as falling into three different categories. So, the first one I think of is dural enhancement or thickening. So that's enlargement or engorgement of the dura, the pachymeninges, and enhancement on postgadolinium imaging. So, that's kind of the first category. The second is that, when you lose spinal fluid volume, other things often expand to take up the space. So, for example, you can get distension or enlargement of the dural venous sinuses, and sometimes you can also get subdural food collections or hematomas. They can arise spontaneously. And I kind of think of those as, you know, you, you've lost the cerebrospinal fluid volume and something else is kind of filling up the space. And then the third category is called brain sagging. And that's a constellation of findings where the posterior fossa structures and the pituitary gland in the cell have become abnormal because you've lost the fluid that normally cushions those structures and causes them to float up. For example, the brain stem will sag down, the distance between the mammillary body and the ponds may become reduced. The suprasellar cistern space may be reduced such that the optic chiasm becomes very close to the pituitary gland, and the prepontine cistern may also become reduced in size. And there are various measurements that can be used to determine whether something is subtly abnormal. But just generally speaking, those are really the three categories of brain MRI abnormalities you'll see. Dr Grouse:  That was a great review. And of course, I think in many times when we are thinking about or suspecting this diagnosis, we may be lucky to find those imaging findings to reinforce a diagnosis. Because as it turns out, after reading your article, I was really surprised to find out that in as many as 19% of cases we actually see normal brain imaging, which really was a surprise to me, I have to say. And I think that this really encompasses why spontaneous intercranial hypotension is such a difficult diagnosis to make. I think a lot of us struggle with how far to take the workup when, you know, spontaneous intercranial hypotension is clinically suspected, but multiple imaging studies are normal. Do you have any guidance on how to approach these more difficult cases? Dr Madhavan:  So, that's a really good question. And you know, it's- as you can imagine, that's a topic that comes up in most meetings where people discuss this, and it's been a continued challenge. And so, like you said, about 19 or 20% of patients who have this disease can have a, a normal brain MRI. And we've tried to do some work to figure out why that is and how we can identify patients who still have the disease. And I can just provide, I guess, some tips that have helped me in my clinical practice. One thing is, if I ever see a patient with a normal brain MRI where this disease is clinically suspected---for example, maybe they have orthostatic headaches or other very typical symptoms and we don't know why, but their brain MRI is normal---the first thing I do is I try to look back at their old imaging. So many times, these patients who present to us at Mayo, who, when we do their MRI scan here, their brain MRI looks normal… if you really look back at imaging that they've had done elsewhere---maybe even two to three years prior---at the time their symptoms started, they actually had some abnormalities. So, I might see that a patient, two years ago, had dural enhancement that spontaneously resolved; but now they still have symptoms of SIH and they may still have a CSF leak that we can find and treat, but their brain MRI has, for whatever reason, normalized. So, I always start by looking back at old imaging, and I found that to be very helpful. The other thing is, if you see a patient with a normal brain MRI, it's also important to look at their spine MRI because that can provide clues that might suggest that they could still have a spinal CSF leak. And the two things I look for on the spine MRI: one, if there's any extradural CSF. So, spinal fluid outside of where it's supposed to be within the confines of the subarachnoid space. And you know, really, if you see extradural CSF, you know they probably have a spinal fluid leak somewhere. Even if their brain MRI is normal, that just gives you the information that there is a dural tear probably somewhere. And so, in those patients we'll definitely still proceed to myelography or other testing, even if they have a normal brain MRI. And then the last thing I look for is whether or not they have prominent meningeal diverticula. Patients with CSF venous fistulas almost always have one or more prominent diverticula on their spine along the nerve root sleeves. And that's probably because most of these fistulas come from nerve root sleeve diverticula. We don't completely understand the pathogenesis of CSF venous fistulas, but they're clearly associated with meningeal diverticula. So, if I see a patient who has a normal brain MRI, but I see on their spine MRI that they have many meningeal diverticula that are relatively prominent, that makes me more inclined to be a little bit more aggressive in doing myelography to find a CSF leak. And then I look at other demographic features, too. So, for example, elevated BMI and older age are associated with CSF venous fistulas. So, that can help you determine whether or not it's warranted to go on to more advanced imaging, too. So those are all just a variety of different things that we've used to help us. Dr Grouse:  Thank you for sharing that. I wanted to go on to say that, you know, reading your article, of course, as you mentioned, you alluded to the fact there's lots of new imaging modalities out there. It was very illuminating and just an excellent resource for the options that exist and when they're useful. You did a great job summarizing it. And I encourage our readers to check out your article, to refresh themselves, update themselves on what's happened in this space. And of course, we can't summarize them all today, but I was wondering if you could possibly walk us through a hypothetical case of a patient who comes in with a history very suspicious for SIH? How would you approach this patient? Say you have gotten imaging that suggested that there is a spinal fluid leak and now you have to figure out where it is. Dr Madhavan:  Yeah. So, you know, I think the most typical scenario it'll be a patient who has been seen by one of my excellent neurology colleagues and they've done a brain MRI and they've made the diagnosis through a combination of clinical information and brain MRI finding. And then the next thing we'll do always is, we'll obtain a spine MRI. So, I think of the purpose of the spine MRI as to determine what type of spinal fluid leak they have. On the spine MRI, if you see extradural CSF, those patients essentially always will have a dural tear. And it may be a ventral dural tear or a lateral dural tear. But if you see extradural CSF, that is pretty much what they have. And conversely, if you don't see extradural CSF---if you just see, for example, many meningeal diverticula, but you don't see anything else particularly abnormal---most of those patients have a CSF venous fistula, just common things being common. So I use the spine MRI to determine what type of leak they have. And then the next thing I think about is, okay, I'm going to do a myelogram on this patient. How do I want to position them? Because it turns out that positioning is probably the most important factor for finding these spinal fluid leaks. You have to have the patient positioned correctly to find the leak that you're trying to localize. And so, if I suspect they have a ventral dural tear, I will always position those patients prone for their myelogram. And I might do one of many different types of myelograms. And, you know, the article talks about things like digital subtraction myelography and dynamic CT myelography. And you can find any of these leaks with any of those techniques, but you just have to have the patient positioned correctly. So, if I think I have a ventral dural tear, I'll put them prone for the myelogram. If I think they have a lateral dural tear, I'll put them in the cubitus position for the myelogram. And also, if they- if I think they have a CSF-venous fistula, I'll also put them in the decubitus position. Obviously if you're putting them in the decubitus position, you have to decide whether it's going to be left or right side down. So that may require a two-day exam. Sometimes you don't have to; in many cases, we're able to just do everything in one day. But those are all the different factors I think about when I'm trying to determine how I'm going to work those patients up further. So, I really use the spine MRI chiefly to think about what type of leak they're going to have and how I'm going to plan the myelogram. Dr Grouse:  That's really great. And it's, I think, really nice to emphasize how much the positioning matters in all this, which I think is not something we've been classically taught as far as the diagnosis of spinal leaks. Another thing I'm really interested in your opinion on is, you talked a lot about how to optimize and what can make you successful at diagnosis. I'm curious what you think one of the easiest mistakes to make or, you know, that we should hopefully avoid when treating patients with this disease. Dr Madhavan:  Yeah. And I think, you know, one other thing that's been discussed a lot in this topic… you know, we've talked about the patients with a normal brain MRI. Another barrier or challenge particularly with CSF-venous fistulas is, sometimes they can be very subtle on imaging. So, it's not always you see it very definitive CSF-venous fistula where you can say, like, there's no question, that's a fistula. There are many times where we do a good-quality myelogram and we see something that looks, like, possible for a CSF venous fistula, or probable. If I had to put a number on it, maybe there's a 50 to 70% chance of real. So, in those cases, we end up wondering, like, should we treat this suspected leak? And I think one common mistake  or one thing that needs to be looked at further is, how do we handle these patients where we don't know whether the fistula is real or not? That's usually something where I will have a discussion with the patient, and I'm usually just very upfront with him about my interpretation of the imaging. I'll just tell them, we did a good-quality myelogram. You did a great job. We got good images. I don't see anything definitive, but I see this thing that I think has maybe a 60% chance of being real. And then I'll confer with one of my neurology colleagues and we'll decide whether it's worth treating that or not. And we'll just be very upfront with a patient about whether- about the likelihood of its success and what their long-term prognosis is. And oftentimes we let them make the decision. But I think that remains to be one of the big challenges is, how do we treat these patients who have suspected leaks that are not definitive on imaging. Dr Grouse:  That sounds absolutely like an important area where there can be problems, so I appreciate that insight. I'm interested what you think in your article would come as the biggest surprise to our listeners who may not have kept up as much with all of the changes that have happened in recent years? Dr Madhavan:  One of the things that was certainly, at least, a surprise to me as I was going through my training and learning about this topic is how diverse myelography has really become. You know, when I was a radiology resident, I learned about myelography as this thing that we've been doing for 30 to 40 years. And historically we've used myelograms just to look for degenerative changes: disc bulges, you know, disc herniations and things like that. Now that MRI is more prevalent, we don't use it as much, but it has turned out that it has a very big role in patients with spinal fluid leaks. Furthermore, something that I've learned is just how diverse these different types of myelograms have become. It used to kind of be just that a myelogram is a myelogram is a myelogram, but now we have different types of positioning, different types of equipment that we use. We vary the timing between contrast injection and imaging to optimize success for finding spinal fluid leaks. So, I think many times I talk to people who may not be as familiar with this field and they're surprised at just how diverse that has become and how sophisticated some of the various myelographic techniques have become and how much that really makes a difference in being able to accurately diagnose these patients. Dr Grouse:  Well, I can say it was a surprise to me. Even as someone who does treat quite a few patients with this condition, I was surprised to see the breadth of different options that have become available. And then kind of a follow-up to that, what do you think the current area of controversy is in this area of diagnosis and treatment? Dr Madhavan:  The biggest ones are ones you've sort of already alluded to. So, one big one is, how far do we go in patients who have a normal brain MRI who still have a clinical suspicion of the disease? And sometimes it's really hard, because sometimes you will find patients who clinically have a very strong case for having spontaneous intracranial hypotension. You look at them, they have very acute-onset orthostatic headaches. There's no better explanation for their symptoms that we know of. And it's hard to know what to do with those patients, because some of them want to continue to undergo diagnostic workup, but you can only do so many myelograms and you can only do so much with this diagnostic workup that requires some radiation dose before it becomes very challenging. That's a major point of just, I guess, ongoing research as to what can we do better for that subset of patients. Fortunately, it's not all of them, it's a subset of them, but I think we could help those patients better in the future as we learn more about the disease. So that's one. And the other one is treating these equivocal findings, like I discussed.  And where should our threshold be to treat a patient, and what type of treatment should we do in patients where we don't know whether a leak is real? Should we just do a very noninvasive- relatively noninvasive blood patch? Do we do an embolization where we're leaving a foreign body there? Is it worth sending those patients to surgery? Those are all unanswered questions and things that continue to spark ongoing debate. Dr Grouse:  Do you think that there's going to be any new big breakthroughs, or even, do you know of any big developments on the horizon that we should be keeping our eyes out for? Dr Madhavan:  You know, I think for me the biggest thing is, imaging is dramatically improving. We talked a little bit about photon counting detector CT in our article, and that's one of the newest and best techniques for imaging these patients because it has very, very high resolution, it has a lower radiation dose, it has allowed us to find leaks that we were not able to find before. And there are other high-resolution modalities that are emerging and becoming more accessible to things like cone beam CT which we do in addition to digital subtraction myelography. And on top of that, we've started to use AI-based tools to make images look a lot better. So, there are various AI algorithms that have come out that allow us to remove artifacts from imaging. They help us image patients with a bigger body habitus better without running into a lot of imaging artifacts. They help us reduce noise in imaging. They can just give us better-quality images and aid us in the diagnosis. For me as a radiologist, those are some of the most exciting things. We're finding less invasive ways with less radiation to better diagnose these patients with just better-quality imaging. Dr Grouse:  Well, that is definitely something to be excited about. So, I just want to thank you so much for talking with us today. It's been such an interesting, informative discussion and a real privilege to talk with you about this important topic. Dr Madhavan:  Yeah, thanks so much. I really appreciate the time to talk with you, and I look forward to seeing the article out there and hopefully getting some interesting questions.

Today, we're speaking to Dr Cini Bhanu, GP and Academic Clinical Lecturer in the Primary Care and Population Health Department at University College London. Title of paper: Antidepressants and risk of postural hypotension: a self-controlled case series study in UK primary careAvailable at: https://doi.org/10.3399/BJGP.2024.0429Antidepressants are associated with postural hypotension (PH). This is not widely recognised in general practice, where antihypertensives are considered the worst culprits. The present study examined >21 000 older adults and found a striking increased risk of PH with use of all antidepressants (over a four- fold risk with SSRIs) in the first 28 days of initiation.

Please be aware it may contain errors or omissions.Speaker A00:00:00.480 - 00:00:56.990Hello and welcome to BJGP Interviews. My name is Nada Khan and I'm one of the associate editors of the bjgp. Thanks for listening to this podcast today.In today's episode, we're speaking to Dr. Cini Banu, who is a GP in an academic clinical lecturer based in the Department of Primary Care and Population Health at University College London.We're here to talk about her recent paper in the BJGP titled Antidepressants and Risk of Postural Hypertension, A Self Controlled Case Series Study in UK Primary Care. So, hi Cinny, it's really nice to meet you today.I guess this is an interesting area to cover, especially as the prescribing rates for some antidepressant medications are increasing.But I don't know what your feeling is, but I'm not sure if many GPs would actually know that antidepressants are associated with poison postural hypertension. So, yeah, talk us through that.Speaker B00:00:57.310 - 00:01:18.350Yeah, so I think that's one of the reasons this study is so important.So definitely from conversations that I've had with gps that I work with and it's not commonly recognized that postural hypotension is associated with antidepressants, though it is by geriatricians, for example, where it's very.Speaker A00:01:18.350 - 00:01:41.850Well recognized and in this study used a big database to look at the risk of new postural hypertension associated with the use of antidepressants in people aged over 60.I guess there's quite a lot of in depth stuff in the methods, but I guess just for a summary for people who are interested in what you did, do you mind just sort of going over it at sort of like a high level?Speaker B00:01:41.850 - 00:02:54.200Yeah, yeah. So we looked at a big database, what we call a routine primary care database called imrd.And essentially this captures data from software that gps use like EMIS and Vision System and captures a whole load of information like problems, symptoms and prescriptions. So we went into this database and identified everyone over the age of 60 that might be eligible during our study period.And for this we looked at people that were contributing at least one full year of data between 2010 and 2018. And then within that we identified people with a first diagnosis of postural hypotension.And then again we made subgroups according to people who had this diagnosis but also had a first prescription of a new antidepressant during that time.And what we were interested in, and the methodology is called a self controlled case series, we weren't interested in who got postural Hypotension, because everyone was a case, but rather...

Spontaneous intracranial hypotension reflects a disruption of the normal continuous production, circulation, and reabsorption of CSF. Diagnosis requires the recognition of common and uncommon presentations, careful selection and scrutiny of brain and spine imaging, and, frequently, referral to specialist centers.  In this episode, Gordon Smith, MD, FAAN speaks with Jill C. Rau, MD, PhD, author of the article “Clinical Features and Diagnosis of Spontaneous Intracranial Hypotension” in the Continuum® June 2025 Disorders of CSF Dynamics issue. Dr. Smith is a Continuum® Audio interviewer and a professor and chair of neurology at Kenneth and Dianne Wright Distinguished Chair in Clinical and Translational Research at Virginia Commonwealth University in Richmond, Virginia. Dr. Rau is an assistant professor of clinical neurology at the University of Arizona, School of Medicine-Phoenix in Phoenix, Arizona.

Dr Smith: This is Dr Gordon Smith. Today I'm interviewing Dr Jill Rau about her article on clinical features and diagnosis of spontaneous intracranial hypotension, which she wrote with Dr Jeremy Cutsworth-Gregory from the Mayo Clinic. This article appears in the 2025 Continuum issue on disorders of CSF dynamics. I'm really excited to welcome you to the Continuum podcast. Maybe you can start by just telling our listeners a little bit about yourself? Dr Rau: Hi, thanks for having me. I'm really honored to be here, and I really enjoyed writing the paper with Dr Cutsforth-Gregory. I hope you guys enjoy it. I am the director of headache medicine at the Baba Bay Neuroscience Institute at Honor Health in Scottsdale, Arizona. I'm also currently the chair of the special interest group in CSF Dynamics at the American Headache Society, and I've had a special interest in this field since I first watched Dr Linda Gray speak at a conference where she talked about spinal CSF leaks and their different presentations. And they were so different than what I had been taught in residency. They're not just the post-LP headache. They have such a wide variety of presentations and how devastating they can be, and how much impact there is on someone's life when you find it and fix it. And I've been super interested in the field and involved in research since that time. And, yeah. Love it. Dr Smith: Well, thanks for sharing your story. And as I reflected on our conversation ahead of time and have been thinking about this issue… this is a cool topic, and every time I read one of these manuscripts and have the opportunity to speak with one of the authors, I learn a ton, because this was something that wasn't even on the radar when I trained back in the 1800's. So, really looking forward to the conversation. I wonder if you could really briefly just summarize or remind for everyone the normal physiology about CSF dynamics, you know, production, absorption, and so forth? Dr Rau: So, the CSF is the fluid that surrounds the brain and the spinal cord, and it's contained by the dura, which is like a canvas or a sac that covers that whole brain and spinal cord. And within the ventricles of the brain, the choroid plexus produce CSF. It's constantly producing and then being reabsorbed by the arachnoid granulations and pushed into the venous space, the cerebral sinuses, venous sinuses. And also some absorption and push into the lymphatics that we've just learned about in the past year. This is kind of new data coming out, so always learning more and more about CSF, but we know that it bathes the brain and the spinal cord, helps keep some buoyancy of the brain as well as pushing nutrients in and pulling out metabolic waste. And it sort of keeps the brain in the state of homeostasis that's happy. And so, when there's a disruption of that flow and the amount of fluid there, that disrupts that, that can cause lots of different symptoms and problems for people. Dr Smith: One of the many new things I learned is that even the name of this---spontaneous intracranial hypotension---is misleading. And I think this is clinically relevant, as we'll probably get to in a moment, but can you talk a little bit about this? Is this really like a pressure disorder or a volume disorder? Dr Rau: Yeah. It's almost certainly a volume disorder. We do see in some people that they have low pressure, and it's still part of the diagnostic criteria. But it's there because if you have a low pressure, if you measure an opening pressure and it's below six, if you're measuring it in the spine in the right place, then you have indication that there's low volume. But there's over 50% of people's opening pressure who have a spinal CSF leak, have all the symptoms and can be fixed. So, they have normal pressure in 50% of the people. So, it is an inaccurate term, hypotension, but it was originally discovered because of the thought that it was a low-pressure situation. Some of the findings would suggest low pressure, but ultimately, we are pretty sure it's a low-volume condition. Dr Smith: Another new thing that I learned that really blew me away is how bad this can be. I did a podcast with Mark Burish about cluster, and I was reminded many cluster patients are pushed to the point of suicidal ideation or committing suicide by the severity of pain. And this sounds like for many patients it's equally severe. Can you maybe paint a picture for our listeners why this is so clinically important? Dr Rau: A large number of people, even people who are known to have leaks because they've had them before or they've releaked, they have a lot of brain fog and cognitive impairment. They often have severe headaches when they're upright. So, orthostatic headache is probably the number one most common symptom, and those headaches are one of the worst headaches out there. When people stand up, their fluid is not supporting the brain and there's an intense amount of pain. And so, they spend a large portion of their lives horizontal. And there's associated symptoms with that, it's not just headache pain and brain fog. There's neck pain. There's often subsequent disorders that accompany this, like partial orthostatic tachycardia syndrome. We don't know if that's because of deconditioning or an actual sequela of the disease, but it's a frequent comorbidity. We have patients that have extreme dizziness with their symptoms, but many patients are limited to hours, if that, upright per day, combined, total. And so they live their lives, often, just in the dark, lots of photophobia, sensitive to the light, really unable to function. It's also very hard to find and so underrecognized that a lot of patients, especially if they don't have that really clinical symptom of orthostatic headache. So, it's often missed. So, they're just debilitated. You know, treatments don't work because it's not a migraine and it's not a typical headache. It's a mechanical issue as well as a metabolic issue and not found, not a lot helps it. Dr Smith: So, you know, I have always thought about this as really primarily an orthostatic symptom. I wonder if you can talk about the complexity of this; in particular, kind of how this evolves over time, because it's not quite that simple. And maybe in doing so, you can give our listeners some pearls on when they should be thinking about this disorder? Dr Rau: A large portion of people do have headache with spinal CSF leak, in particular, spontaneous intracranial hypertension- hypotension, excuse me. And that's something to be thought about, is that there are spontaneous conditions where people have either rupture of the dural sac, or an erosion of the dural sac, or a development of a connection between the dura and the venous system. And that is taking away or allowing CSF to escape. In these instances that patients have spontaneous, there may be a different presentation than if they have, like, a postdural puncture or a chronic traumatic or iatrogenic leak. And we're not sure of that yet, but we're looking into that. Still, the largest presentation is headache, and orthostatic headache is very dominant in the headache realm. But over time, patients' brains can compensate for that lack of CSF and start overproducing---or at least we think that's probably what's happening. And you may see a reduction in the orthostatic symptoms over time, and you may see an improvement in the radiographic findings. So, there are some interesting papers that have been published that look at these changes over time, and we do see that sometimes within that first three to four months; this is the most common time to see that change. Other patients may worsen. You may actually see someone going from looking sort of normal radiographically to developing more of a SIH-type of picture on the brain. And so it's not predictable which patients have gone from orthostatic to improvement or the other way around, both radiographically and clinically. So, it can be quite difficult to tell. So, for me, if I have a patient that comes to me and they're struggling with headache… if it's orthostatic, very clearly orthostatic: I lay down, I get considerably better or my headache completely goes away. And then when I stand up, it comes on relatively quickly, within an hour. And sometimes it's a worsening-throughout-the-day type of thing, it's lowest in the morning and it worsens throughout the day. These are the times that it's most obvious to think about CSF leak. Especially if that headache onset relatively suddenly, if it onset after a small trauma. Like I've had patients that say, you know, I was doing yoga and I did some twists and I felt kind of a pop. And then I've had this headache that is horrible when I'm upright but is better when I lay down ever since, you know, since that time. That's kind of a very classic presentation of spinal CSF leak or spontaneous intracranial hypotension. Maybe a less common presentation would be someone who comes to you, they've had a persistent headache for a couple years, they kind of remember it started in March of a couple years ago, but they don't know. Maybe it's, you know, it's a little better when they lay down. It may be a little worse when they're up moving around, but so is migraine, and it's a migrainous headache. But they've tried every migraine drug you can think of. Nothing is responding, nothing helps. I'm always looking at patients who are new daily, persistent headaches and patients who aren't responding to meds even if it's not new daily, but they have just barely any response. I will always go back and examine their brain imaging and get full spine to make sure I'm not missing. And you can never be 100% sure, but it's always good to consider those patients to the best of your ability, if that- have that in the back of your mind. Dr Smith: So obviously, goes without saying, this is something people need to have on their radar and think about. And then we'll talk more about diagnostic tools here in a second. But how common is this? If you're a headache doc, you see a lot of patients who have intractable headaches. And how often do you see this in your headache practice? Now you're- this is your thing, so probably a little more than others, but, you know, how common will someone who sees a lot of headache encounter these patients? Dr Rau: If you see a lot of headache, I mean, currently the thought is it's about 5 in 100,000. That was from a study before we were finding CSF venous fistulas. I think a lot of us think it's more common than that, but it's not super common. We don't have good estimates, but I would guess between 5 and 10 for 100,000 persons, not “persons who come to a tertiary headache clinic with intractable headaches”. So, it's hard to gauge how frequent it is, but I would say it's considerably more frequent than we currently think it is. There's still a group of people with orthostatic headaches that we can't find leaks on; that, once you treat other things that can cause or look for other things that can cause orthostatic headaches. So, there may be even still a pathophysiology out there that is still a leak type. Before 2014, we didn't even know about CSF venous fistulas. And now here we are; like, 50% of them are CSF venous fistulas. So, you know, we're still in a huge learning curve right now. Dr Smith: So, I definitely want to talk about the fistulas in a second. But before moving on, one of the things that I found really interesting is the wide spectrum of clinical phenotype. And we obviously don't have a lot of time to get into all of these different ones, but the one that I was hoping you might talk about---and there's a really great case, and you're on bunch of great case, a great case of this---is brain sagging dementia, not a term I've used before. Can you really briefly just tell our listeners about that, because that's a really interesting story and a great case in your article? Dr Rau: Yeah. So, brain sag dementia is a… almost like an extreme version of a spontaneous intracranial hypotension. Where there is clear brain sag in the imaging---so that's helpful---but the patients present kind of like a frontotemporal dementia. And when this was first started to being determined, you could turn the patient into Trendelenburg, and sometimes they would improve. There are some practitioners that have introduced fluid into the thecal sac and had temporary improvement. Patching has improvement, then they leak again, sometimes  not. But the clinical changes with this have been pretty tremendous to be able to identify that that's a real thing. And in some cases, out of Cedars Sinai, you know, who does a lot of the best research in this, they've had lots of cases where they can't find the leak, but there's clear brain sag that fits with our clinical picture of CSF leaks. So, we're on a learning curve. But yeah, this- they really present. They have disinhibition and cognitive impairment that is very similar to frontotemporal dementia. Dr Smith: Well, so let's talk about what causes this. You mentioned CSF venous fistulas. I mean, that was reported now just over a decade ago, it's pretty amazing. That accounts for about half of cases, if I understand correctly. What are the other causes? And then we'll talk more about therapy in a minute, but what causes this? Dr Rau: So, within the realm of spontaneous, you know, we say it's spontaneous. But the spontaneous cases we account for, they can be tears in the dura, which are usually sort of lateral tears in the dura. They can be little places that rubbed a hole, often on an osteophyte from the spine. They can come from these spinal diverticuli. So, I always describe it to my patients like those balls that have mesh and squishy, and you squeeze them in the- through the mesh, there's the extra little bubbling out. If you think of like the dura bubbling, out in some cases, through the framing of the spine, right where the spinal nerve roots come out, they should poke out like wires from the dura. But in many cases they poke out with this extra dura surrounding them, and we call that spinal diverticuli. And if you imagine like the weakening of where you squeeze that, you know, balloon through your fingers, in those locations, that's a very common place to find a CSF leak, and you can imagine that the integrity of the dura there may be less than it would be if it were not being expanded in that direction. And that's often the most common place we see these CSF venous fistulas. So, you can get minor traumas; like I said, it can be spontaneous, like someone just develops a leak one day. It can be rubbed off, and it can be a development of a connection between the dura and the venous system. There are also iatrogenic causes, but we don't consider them spontaneous. But when you're considering your patients for spontaneous cases, you should consider if they've ever had chronic---even long, long time ago---had any spinal implementation, procedures near the spine, spinal injections, LPs in the past, and especially women who've had epidurals in pregnancy. Dr Smith: All right, so we see a patient, positional severe headache, who meets the clinical criteria. Next step, MRI scan? Dr Rau: Yeah. So, the first thing is always to get the brain MRI with and without contrast. Most places will have a SIH or a spinal CSF leak protocol, but you should get contrast because one of the most pathognomonic findings on brain MRI is that smooth diffuse dural enhancement. And that's a really fantastic thing when you find it, because it's kind of a slam dunk. If you find it, then you will see other findings. It almost never exists alone. But if you see that, it's pretty much a spinal CSF leak. But you're also looking for subdural collections, any indication of brain sag. We do have these new algorithms that have come out in the past couple of years that are helpful. They're not exclusionary---you can have negative findings on the brain and still have spinal CSF leak---but the brain MRI is extremely helpful. If it's positive for the findings, it really does help you nudge you in the direction of further investigations and treatments. Dr Smith: And what about those further investigations and treatments, right? So, you see that there's findings consistent with low pressure, and I guess I should say low intracranial CSF volume. Be that as it may, what's the next step after that? Dr Rau: Depends on where you are and what you can do. I almost always will get a full spine MRI: so, C spine, T spine, and L spine separately. Not, you know, we don't want it all in one picture, because we want to get the full view. And you want to get that with at least T2 highly- heavily T2 weighted with fat saturation in at least the sagittal and axial planes. It's really helpful if you can get it in the coronal planes, but we have to have- often have good talks with your radiologist to get the coronal plane. I spoke about the spinal diverticuli earlier, and I want to clarify a little bit of something. The coronal image will show those really nicely. It's interesting, but 44% of people have those. So just having the spinal diverticuli does not indicate that you have a leak. But if you have a lot of those, there may be more likelihood of having leak than if you don't have any of those. So, I will get all of those and I will look at them myself, but I've been looking at them myself for a long time. But a lot of radiologists in community hospitals, especially not- nonneuroradiologists, but even neuroradiologists, this isn't something that's that everybody's been educated about, and we've been learning so much about it so rapidly in the past ten years. It's not easy to do and it's often missed. And if it's not protocoled properly, the fat saturation's not there, it's very hard to see… you can have a leak and not see it. Even the best people, like- it's not always something that's visible. And these CSF venous fistulas that we talked about are never visible on normal MRI imaging. Nonetheless, I will run those because if I can find a leak---and 90% of the ones that are found on MRI imaging are in the thoracic spine. So that's where I spend the most of my time looking. But if you find it, that's another thing to take to your team to say, hey, look, here it is, let's try and do this, or, let's try and do that, or, I've got more evidence. And there are other findings on the spine; not just the leak, but other findings, sometimes, you can see on spine that maybe help you push you towards, yes, this is probably a leak versus not. Dr Smith: So, your article has a lot of great examples and detail about kind of advanced imaging to, like, find the fistula and what not. I guess I'm thinking most of our listeners are probably practicing in a location where they don't have a team that really focuses on that. So, let's say we do the imaging of the spine and you don't find a clear cause. Is the next step to just do a blood patch? Do you send them to someone like you? What's the practical next step? Dr Rau: Yeah, if your- regardless of whether you find a leak or not, if your clinical acumen is such that you think this patient has a leak or I've treated them for everything else and it's not working and I have at least a high enough suspicion that I think the risk of getting a patch is lower than the benefit that if they got a patch and it worked, I do send my patients for non-directed blood patches, because it currently does take a long time to get them to a center that can do CT myelograms or any kind of advanced imaging to look for sort of a CSF venous fistula or to get treated outside of a nondirected patch. You know, sometimes nondirected patches are beneficial for patients, and there's some good papers out there that sort of explain the low risks of doing these if done properly versus the extreme benefit for patients when it works. And, I mean, I can't tell you how many people come in and tell me how their lives are changed because they finally got a blood patch. And sometimes it works. And it's life-changing for those people. You know, they go back to work. They can interact with their kids again. Before, they didn't know what was wrong, just had this headache that started. So it's worth doing if you have a strong clinical suspicion. Dr Smith: Yeah. I mean, that was great. And, you know, to go back to where we began, this is severe. It's something like 60% of patients with this problem have thought about suicide, right? And you take this patient and cure the problem. I feel really empowered having read the article and talked to you today. And so, I'm ready to go out and look for this. Thank you so much for a really engaging conversation. This has been terrific. Dr Rau: Thank you. I appreciate it. I enjoyed being here. Dr Smith: Again, today I've been interviewing Dr Jill Rau about her article on clinical features and diagnosis of spontaneous intracranial hypotension---which I guess I should say hypovolemia after having talked to you---which she wrote with Dr Jeremy Cutsworth-Gregory.

Irbesartan is an angiotensin II receptor blocker (ARB) used primarily for the management of hypertension and diabetic nephropathy in type 2 diabetes. It selectively inhibits the binding of angiotensin II to the AT1 receptor found in vascular smooth muscle and the adrenal gland. This blockade results in vasodilation, reduced aldosterone secretion, decreased sodium and water retention, and ultimately lower blood pressure. Irbesartan is administered orally, with a typical starting dose of 150 mg once daily, which may be increased to 300 mg depending on the patient's clinical response and tolerability. Adverse effects of irbesartan are generally mild but can include hyperkalemia and dizziness. Hypotension may occur, especially in volume-depleted individuals or those on diuretics. Routine monitoring of renal function and serum potassium is recommended, especially in patients with underlying kidney disease or those taking potassium-sparing agents or supplements. Irbesartan is contraindicated in pregnancy due to the risk of fetal toxicity and should be discontinued as soon as pregnancy is detected.

Dr. K explains what counts as low blood pressure, why it becomes common with aging, when it can be dangerous, and what to do about it. She also explains orthostatic hypotension, a common problem that affects many older adults and can lead to symptoms, such as dizziness or even falls.

It's that time of year again. Let's finish the year off strong with your favorite podcasts. Don't worry...I already have new episodes in the pipe starting in January. In this episode of the PFC Podcast, Dennis and Jeff delve into the complexities of anoxic brain injury, discussing its causes, recovery processes, and prevention strategies in tactical environments. They emphasize the importance of monitoring, airway management, and resuscitation goals, while also addressing the management of hypotension and shock. The conversation highlights the significance of preventing secondary brain injuries and the role of basic medical practices in saving lives. Takeaways Anoxic brain injury is caused by a lack of oxygen to the brain. Recovery from brain injuries can take time and various therapies. Preventing blood loss is crucial in tactical environments. Monitoring oxygen saturation is essential for early detection. Airway management decisions should be based on the patient's condition. Resuscitation goals should focus on maintaining adequate blood pressure and oxygen levels. Hypotension can arise from various causes and needs to be managed effectively. Resuscitation targets should aim for optimal blood pressure and oxygen saturation. Preventing secondary brain injuries is critical for patient outcomes. Basic medical practices can significantly impact survival rates.

Contributor: Aaron Lessen MD Educational Pearls: Induction agent selection during rapid sequence intubation involves accounting for hemodynamic stability in the post-intubation setting Many emergency departments use ketamine or etomidate A recent study sought to explore the rates of post-induction hypotension of ketamine compared with propofol Single center retrospective cohort study of patients between 2018-2021 Ketamine and propofol were both significantly associated with post-induction hypotension Ketamine adjusted odds ratio = 4.50 Propofol adjusted odds ratio = 4.88 50% of patients became hypotensive after induction with either propofol or ketamine These findings suggest post-induction hypotension is mainly due to sympatholysis rather than the choice of agent itself References Tamsett Z, Douglas N, King C, et al. Does the choice of induction agent in rapid sequence intubation in the emergency department influence the incidence of post-induction hypotension?.

In this episode, researchers explore how asymptomatic versus symptomatic hypertension affects heart failure patients on sacubitril valsartan, finding that both types are linked to worse outcomes, but the drug's benefits remain strong, suggesting clinicians should avoid stopping treatment based solely on blood pressure.

Recorded at the recent American Association of Nurse Anesthesiology meeting this piece focuses upon the importance of addressing intraoperative hypotension (IOH) and its broader implications for patient outcomes, such as surgical site infections (SSI), postoperative cognitive dysfunction, and other complications. We also discuss the need for continuous education and the use of goal-directed therapy (GDT) to improve patient care.
