Multiple endocrine neoplasias are familial syndromes of endocrine tumors occurring in endocrine organs throughout the body. Despite its acronym, the risk for acquiring MEN is about the same in men and women and also across geographic and racial and ethnic groups. These are rare syndromes, affecting about 1 in 30,000 people. Genetic mutations cause the MEN syndromes, which are then inherited in an autosomal dominant pattern. This means several members of the same family are often affected; an affected parent has a 50% chance of passing down the disease to his or her children. Unlike cancers without a hereditary basis, tumors associated with MEN often occur in younger patients (under age 40 years) and affect multiple organ systems all at once, making them particularly troublesome. Generally, tumors may arise in the pituitary gland, parathyroid glands, thymus, pancreas, thyroid, or adrenal glands (Figure 1). The three major types of multiple endocrine neoplasia are MEN1, MEN2A, and MEN2B, and each has a characteristic picture of endocrine or neurologic disorders and tumors. After listening to this AudioBrick, you should be able to: Define multiple endocrine neoplasia (MEN), and list the three MEN syndromes. Compare and contrast the main clinical features of MEN1, MEN2A, and MEN2B. Describe the genetic defects that cause MEN1, MEN2A, and MEN2B. Briefly describe the management of the MEN syndromes.

Neoplasia is a rare finding in ORS/Ovarian Remnant Syndrome In the literature as of 2023, 13 cases of adenocarcinoma and malignancy developing in an ovarian remnant have been described to date. 2 cases of clear cell adenocarcinoma, 2 of mucinous tumor types, 5 of endometrioid types, 3 of adenocarcinomas and 1 of border serous neoplasia. Lower back pain, dyspareunia, variable bowel symptoms, pelvic masses or ureteral compression have also been encountered. In patients with ovarian cancer developing in ovarian remnants, the most common presenting symptom is severe, persistent pain. In 3 patients, the presenting sign is a pelvic mass found incidentally during routine check-up. ** I am case #13 NIH/Rare Cancer Research/Institutes ORS/Ovarian Remnant Syndrome ❤️

Link to bioRxiv paper: http://biorxiv.org/cgi/content/short/2023.06.28.544680v1?rss=1 Authors: Vandepas, L. E., Crim, R. N., Gilbertson, E., Yonemitsu, M. A., Unsell, E., Metzger, M. J., Lacy-Hulbert, A., Goetz, F. W. Abstract: Disseminated neoplasia (DN) is a form of cancer in bivalve molluscs that has been reported in some cases to be a transmissible cancer. Neoplastic cells are highly proliferative, and infection is often lethal. Some commercially valuable bivalve species (mussels, cockles, soft-shell clams, oysters) are affected by outbreaks of disseminated neoplasia, making disease diagnosis and mitigation an important issue in aquaculture and ecological restoration efforts. Here we describe a minimally invasive, non-lethal method for high-throughput screening for disseminated neoplasia in basket cockles (Clinocardium nuttallii). Basket cockles are native to the North American Pacific coast from California to Alaska. There is recent concern from some Coast Salish Tribes regarding an observed long-term decline in cockle populations in Puget Sound, WA. This has led to increased interest in monitoring efforts and research to improve our understanding of the mechanisms of observed basket cockle population dynamics, including assessing prevalence of disease, such as disseminated neoplasia. The rapid, non-lethal hemolymph smear screening method presented here to diagnose DN in adult C. nuttallii can be applied at field sites at low financial cost, and in a validation study of 29 animals the results were identical to that of the gold standard method, tissue histology. Due to the similar morphology of DN in different bivalves, this method can likely be generally applied for use in any bivalve species. Copy rights belong to original authors.

Cristian was diagnosed with multiple endocrine neoplasia type 1 (Men1), also know as Wermer's Syndrome, at the age of 17 (2003), after doctors found hypercalcemia. MEN1 is a rare heritable disorder that predisposes individuals to tumors in the pituitary and parathyroid glands, and pancreas. In 2014, hypercalcemia was found again, performing a neck ultrasound that indicates a new parathyroid adenoma and a thyroid lesion, so a second parathyroidectomy was performed, extracting only the affected gland and a partial thyroidectomy. Following with his annual controls, in May/2017, by ultrasound images a 2x2cm lesion was diagnosed in the pancreas, so a laparoscopic pancreaticoduodenectomy (Wipple surgery) was performed. In this interview, we talk about: - Cristian's MEN1 journey and living with tumors in his brain, neck and pancreas - How Cristian has developed and maintains a positive attitude despite all the adversity that's been thrown at him - What it was like getting life-saving surgery on his pancreas - His life perspective on adversity, low points, resiliency, success, support and gratitude __ Cristian's Email: cleiva1@babson.edu Cristian's Instagram: https://www.instagram.com/crleiger/ Time Stamps: 0:52 Cristian's background 2:32 Did you know what MEN1 was prior to your diagnosis at 17? 3:15 How did you find out about the MEN1 diagnosis?

PETCast #48 No nosso quadragésimo oitavo PETCast, trouxemos o Dr. Marcos Flávio para abordar um caso de Neoplasia de Próstata, com ddx de Hiperplasia Prostática Benigna.
We're a little late with this one- TDMG had to get the firmware of his MKULTRA chip upgraded so he was laid up for a couple days. But what's more important than his improved 5G reception and newfound need to explore the Marvel Cinematic Universe is that we have a new episode for all our children. Usually there's a binding thematic thread of some kind for these episodes, but definitely not on this one- we're exploring all corners of extreme music this time. Opening the episode is the debut full-length of Sorguinazia, who play with the expectations of Candian war metal by providing, instead, a dedicated and traditional interpretation of 2nd wave black metal. The rhythms are complex and the presentation is vicious, but the cold, black heart of Mayhem beats steady just under its surface. Why did we stop calling things "necro" anyway? Next is Dark Fog Eruption, a one-man project from Japan playing a style of black metal hard to pin down. Laced with heavy metal, DSBM, and minimal interpretations of soaring Swedish black/death, this is a project with tendrils extending into multiple dimensions of underground black metal in search for a precise center. Is there a Japanese black metal sound? It's hard to say- but we have a good discussion over what it might be. After our break comes Neoplasia, a needling, sadistic, and deliberately distressing take on tech death from Argentina. Now featuring the legendary Lord Marco behind the drums, Neoplasia makes music that recalls your first memories of hearing Necrophagist or Spawn of Possession, but filtered through hideous, blood-flecked industrial machinery and played at double speed. This might be the fastest and most technically accomplished record we've ever covered on the show. Wrapping things up, we abruptly switch gears with the debut record by Harul Vinay, a Himalayan neofolk artist who merges both European and subcontinental instrumentation with an insistent streak of black metal songwriting technique. TBMG takes the helm here (being the one who actually knows things about this kind of music) and prompts a discussion about what defines neofolk, how metal music relates to it, and where this project can develop in the future. 0:00:00 - Intro 0:07:59 - Sorguinazia - Negation of Delirium (Iron Bonehead) 0:49:36 - Dark Fog Eruption - 忘却と絢爛の幻想 (The Illusion of Oblivion and Opulence) (Independent) 1:31:04 - Interlude - Hakuja - “Dew of Blood,” fr.

Multiple Endocrine Neoplasia is a difficult diagnosis for patients, families, and clinicians. The vast array of symptoms, affected organs, and complex genetics often mean that it can take years (if not longer) for it to be diagnosed. In addition, the impact for the patient is significant as it is a familial disease that is autosomal dominant with very high penetrance. These syndromes were only identified around the 1960s. However, clinical suspicions were unable to be confirmed as the molecular/genetic techniques only in its infancy. It is a rare condition but one that is critical to recognise early to ensure we provide the best care and management for patients and their families. Special Guest Mark A. Lewis, MD, is director of gastrointestinal oncology at Intermountain Healthcare in Utah. Specializing in cancers of the gastrointestinal tract and accessory organs, his interests focus on hereditary cancer syndromes and young-onset cancers, shared decision-making, and patient-physician communication. The death of his father not only took a huge emotional toll on Lewis, but also piqued his intellectual curiosity. Lewis' paternal uncle and grandfather both died of rare cancer types and then Lewis was diagnosed with a suspicious symptom himself – hypercalcemia, or high levels of calcium – something his father had also experienced.

The vast array of symptoms, affected organs, and complex genetics often mean that it can take years (if not longer) for it to be diagnosed. In addition, the impact for the patient is significant as it is a familial disease that is autosomal dominant with very high penetrance. These syndromes were only identified around the 1960s. However, clinical suspicions were unable to be confirmed as the molecular/genetic techniques only in its infancy. It is a rare condition but one that is critical to recognise early to ensure we provide the best care and management for patients and their families. Special GuestMark A. Lewis, MD, is director of gastrointestinal oncology at Intermountain Healthcare in Utah. Specializing in cancers of the gastrointestinal tract and accessory organs, his interests focus on hereditary cancer syndromes and young-onset cancers, shared decision-making, and patient-physician communication. The death of his father not only took a huge emotional toll on Lewis, but also piqued his intellectual curiosity. Lewis' paternal uncle and grandfather both died of rare cancer types and then Lewis was diagnosed with a suspicious symptom himself – hypercalcemia, or high levels of calcium – something his father had also experienced.

Multiple endocrine neoplasias are familial syndromes of endocrine tumors occurring in endocrine organs throughout the body. Despite its acronym, the risk for acquiring MEN is about the same in men and women and also across geographic and racial and ethnic groups. These are rare syndromes, affecting about 1 in 30,000 people. Genetic mutations cause the MEN syndromes, which are then inherited in an autosomal dominant pattern. This means several members of the same family are often affected; an affected parent has a 50% chance of passing down the disease to his or her children. Unlike cancers without a hereditary basis, tumors associated with MEN often occur in younger patients (under age 40 years) and affect multiple organ systems all at once, making them particularly troublesome. Generally, tumors may arise in the pituitary gland, parathyroid glands, thymus, pancreas, thyroid, or adrenal glands (Figure 1). The three major types of multiple endocrine neoplasia are MEN1, MEN2A, and MEN2B, and each has a characteristic picture of endocrine or neurologic disorders and tumors.

E se il tuo animale ha un nodulo, una neoplasia cutanea probabilmente maligna?La prima cosa che farà il tuo medico veterinario sarà dare un nome e cognome alla neoformazione e lo farà tramite biopsia, ovvero preleverà un campione delle cellule del nodulo perché siano analizzate in laboratorio.A questo punto sarà possibile instaurare una terapia più mirata e a volte, come nel caso del comunissimo mastocitoma del cane, saranno necessarie indagini aggiuntive per capire se la neoplasia si trova solo sulla pelle o se purtroppo ha raggiunto anche altri organi come i linfonodi, il fegato, la milza o il midollo osseo.Negli esseri umani come negli animali esistono patologie di ogni tipo, molte sono curabili, alcune, purtroppo, non lo sono. Se noti una neoformazione sulla cute del tuo cane o gatto non esitare: chiedi un consulto medico veterinario perché quello che può essere curato subito, potrebbe non esserlo più se attendi troppo.

Already a number of large health organizations have trashed the study, which goes against years of advice to cut down on meat and eat more veggies. But authors say their conclusions are based on the most comprehensive review of the evidence ever made. The PSA test for prostate specific antigen is the closest thing doctors have to a screening test for prostate cancer, but it often produces false positives leading to risky and unnecessary biopsies. Now a study in the journal Neoplasia finds that a urine test for a genetic biomarker can accurately detect one form of prostate cancer affecting about a third of men with cancer. The test would have to be used in conjunction with tests for other cancer biomarkers.

Expert Approach to Hereditary Gastrointestinal Cancers presented by CGA-IGC
The 2019 season of the CGA-IGC podcast series, Expert Approach to Hereditary Gastrointestinal Cancers, will focus on the management of extra-colonic features of Familial Adenomatous Polyposis, or FAP. FAP is an inherited condition that is primarily characterized by the development of many colon polyps and an increased risk for colon cancer, but there are other aspects of FAP that are also important to be aware of and manage appropriately. The third episode features Dr. Jewel Samadder, gastroenterologist and advanced endoscopist at the Mayo Clinic in Phoenix, Arizona. Dr. Samadder has a specific focus on hereditary cancer conditions, with distinct expertise in familial adenomatous polyposis. In this episode, Dr. Samadder discusses the necessary screening, endoscopic and surgical approaches, and chemoprevention options for duodenal neoplasia in FAP.

Objective: Diagnostic imaging by CT colonography and capsule endoscopy is used to detect colonic lesions. Controversy exists regarding the work-up of subcentimetric lesions. The aim of this study was to identify risk indicators for advanced neoplasia (AN) in subcentimetric polyps. Design: Colonoscopies were classified on the basis of the largest lesion found. AN was defined as high-grade dysplasia, villous histology, or cancer. Logistic regression models were developed to identify risk factors for AN, and validated on separate datasets. A risk index based on the logistic regression was generated, and the number needed to screen (NNS) to detect AN was determined. Results: 1 077 956 colonoscopies identified 106 270 intermediate (5-9 mm) and 198 954 diminutive (= 85 versus = 85 versus

Colorectal cancer (CRC) is one of the leading causes of cancer related morbidity and death. Despite the fact that the mean age at diagnosis of CRC is lower in men, screening by colonoscopy or fecal occult blood test (FOBT) is initiated at same age in both genders. The prevalence of the common CRC precursor lesion, advanced adenoma, is well documented only in the screening population. The purpose of this study was to assess the risk of advanced adenoma at ages below screening age. We analyzed data from a census of 625,918 outpatient colonoscopies performed in adults in Bavaria between 2006 and 2008. A logistic regression model to determine gender- and age-specific risk of advanced neoplasia was developed. Advanced neoplasia was found in 16,740 women (4.6%) and 22,684 men (8.6%). Male sex was associated with an overall increased risk of advanced neoplasia (odds ratio 1.95; 95% confidence interval, CI, 1.91 to 2.00). At any age and in any indication group, more colonoscopies were needed in women than in men to detect advanced adenoma or cancer. At age 75 14.8 (95% CI, 14.4-15.2) screening, 18.2 (95% CI, 17.7-18.7) diagnostic, and 7.9 (95% CI, 7.6-8.2) colonoscopies to follow up on a positive FOBT (FOBT colonoscopies) were needed to find advanced adenoma in women. At age 50 39.0 (95% CI, 38.0-40.0) diagnostic, and 16.3 (95% CI, 15.7-16.9) FOBT colonoscopies were needed. Comparable numbers were reached 20 and 10 years earlier in men than in women, respectively. At any age and independent of the indication for colonoscopy, men are at higher risk of having advanced neoplasia diagnosed upon colonoscopy than women. This suggests that starting screening earlier in life in men than in women might result in a relevant increase in the detection of asymptomatic preneoplastic and neoplastic colonic lesions.
A study in the November issue of Gastroenterology investigates whether detection of proximal nondysplastic serrated polyps (ND-SP) at screening and surveillance colonoscopies is associated with advanced neoplasia.
An AGA medical position statement and technical review on the diagnosis and management of colorectal neoplasia in inflammatory bowel disease appear in the February 2010 issue of Gastroenterology. Dr. Kuemmerle speaks with author Dr. Francis A. Farraye.

Marek´s disease virus (MDV) is a herpesvirus causing a lymphoproliferative disorder of domestic chickens worldwide. The early signs of disease like apathy, anorexy and the transient paralysis as well as the symptoms at the later stages (Neoplasia and death) causes large economical problems in the chicken industry. With the development of an effetive Vaccine, the first practical vaccine against an oncogenic disease of any type in any spieces, most of the serious problems were solved. However recent reports describing an increased virulence resulting in vaccine breaks, indicates a demand for better vaccines. To be able to enhance the prophylaxis against Marek´s disease virus, the understanding of the interaction between host and virus needs to be expanded. Interferons are cytokines with antiviral activity. On the basis of their structural and functional features they can be divided into type I (IFN-alpha and IFN-beta) and type II (IFN-gamma) interferons. Type I plays an important role during the early phase of viral infections, while IFN-gamma has a prominent role later during the infection through its immunmodulatory functions. In this study it was shown that chicken embryocellcultures responds to the infection with either an apathogenic strain of MDV (CVI 988) or a highly pathogenic strain (RB1B), with the secretion of an antiviral factor. Neutralisation with cytokine specific antibodies revealed that this activity could only be attributed to IFN-alpha but not IFN-beta. In addition, synthesis of IFN-gamma was not observed in any of the experiments. Treatment of MDV infected embryocellcultures with either recombinant chicken IFN-alpha (rChIFN-alpha) or recombinant chicken IFN-gamma (rChIFN-gamma) led to a significant reduction in plaque numbers. This antiviral effect was still observed when cultures were treated 48 hours after infection. In order to understand the functional role of the IFNs in vivo, leghorn birds were repeatedly treated with rChIFN-alpha or rChIFN-gamma for ten weeks starting on the day of hatch. The birds were then challanged on the second day of life with a highly virulent MDV-strain (vv+, EU-1). Treatment with IFN-gamma delayed the mortality to a very small degree. In contrast, IFN-alpha treatment delayed the mortality for 3 weeks. However, prevention of the disease was not achieved regardless of the used IFN-alpha dose. The functional relevance of IFN-alpha was further underscored by experiments where birds were treated with a neutralizing monoclonal antibody to ChIFN-alpha and thereafter infected with the EU-1 strain at the second day of life. Birds in this group died 3 weeks earlier than those in the untreated control group. These data shows that Interferons play a role in the progression of Mareks disease, however, regardless the IFN-dose applicated, the disease could not be prevented by the cytokines on their own.
Commonly, plant and invertebrate lectins are accepted glycohistochemical tools for the analysis of normal and altered structures of glycans in histology and pathology. Mammalian lectins and neoglycoproteins are recent additions to this panel for the detection of lectin-reactive carbohydrate epitopes and glycoligand-binding sites. The binding profiles of these three types of probes were comparatively analyzed in normal, inflamed and neoplastic large intestine. In normal colonic mucosa the intracellular distribution of glycoconjugates and carbohydrate ligand-binding sites in enterocytes reveals a differential binding of lectins with different specificity and of neoglycoproteins to the Golgi apparatus, the rough and smooth endoplasmic reticulum and the apical cell surface. The accessible glycoligand-binding sites and the lectin-reactive carbohydrate epitopes detected by galectin-1 show the same pattern of intracellular location excluding the apical cell surface. Lectin-reactive carbohydrate epitopes detected by plant lectins of identical monosaccharide specificity as the endogenous lectin {[}Ricinus communis agglutinin-I (RCA-I), Viscum album agglutinin (VAA)], however, clearly differ with respect to their intracellular distribution. Maturation-associated differences and heterogeneity in glycohistochemical properties of epithelial cells and non-epithelial cells (macrophages, dendritic cells, lymphocytes) are found. Dissimilarities in the fine structural Ligand recognition of lectins with nominal specificity to the same monosaccharide have been demonstrated for the galactoside-specific lectins RCA-I, VAA and galectin-1 as well as the N-acetylgalactosamine (GalNAc)-specific lectins Dolichos biflorus agglutinin (DBA), soybean agglutinin (SBA) and Helix pomatia agglutinin in normal mucosa and in acute appendicitis. Acute inflammation of the intestinal mucosa found in acute phlegmonous appendicitis is associated with selective changes of glycosylation of mucin in goblet cells mainly of lower and middle crypt segments resulting in an increase of DBA- and SEA-binding sites in the goblet cell population. Appendicitis causes no detectable alteration of neoglycoprotein binding. In contrast, tumorigenesis of colonic adenoma is characterized by increases in lectin-reactive galactose (Gal; Gal-beta 1,3-GalNAc), fucose and N-acetylglucosamine moieties and by enhanced presentation of respective carbohydrate ligand-binding capacity. This work reveals that endogenous lectins and neoglycoproteins are valuable glycohistochemical tools supplementing the well-known analytic capacities of plant lectins in the fields of gastrointestinal anatomy and gastroenteropathology.
It has been suggested that not only the position but also the nature of the mutations of the ret protooncogene strongly correlate with the clinical manifestation of the multiple endocrine neoplasm type 2 (MEN 2) syndrome. In particular, individuals with a Cys634-Arg substitution should have a greater risk of developing parathyroid disease. We, therefore, analyzed 94 unrelated families from Germany with inherited medullary thyroid carcinoma (MTC) for mutation of the ret protooncogene. In all but 1 of 59 families with MEN 2A, germline mutations in the extracellular domain of the ret protein were found. Some 81% of the MEN 2A mutations affected codon 634. Phenotype-genotype correlations suggested that the prevalence of pheochromocytoma and hyperparathyroidism is significantly higher in families with codon 634 mutations, but there was no correlation with the nature of the mutation. In all but 1 of 27 familial MTC (FMTC) families, mutations were detected in 1 of 4 cysteines in the extracellular domain of the ret protooncogene. Half of the FMTC mutations affected codon 634. Mutations outside of codon 634 occurred more often in FMTC families than in MEN 2A families. In all but 1 of 8 MEN 2B patients, de novo mutations in codon 918 were found. These data confirm the preferential localization of MEN 2-associated mutations and the correlation between disease phenotype and the position of the ret mutation, but there was no correlation between the occurrence of hyperparathyroidism or pheochromocytoma and the nature of the mutation.
