Metastatic Melanoma Invading the Minor Duodenal Papilla in a Patient With Pancreas Divisum Causing Acute Recurrent Pancreatitis: A Case Report.

Metastasis to the gastrointestinal (GI) tract should always be a consideration when melanoma, particularly metastatic disease, is diagnosed. While metastasis to the small intestine is common, given its rich blood supply, metastasis to the pancreatic ducts is extremely rare. In patients with pancreatic divisum, disease spread to the minor papilla can greatly increase the chance of developing pancreatitis due to the potential for increased pancreatic intraductal pressure. We present one unique case of metastatic melanoma to the minor duodenal papilla causing pancreatitis.

Ureterosciatic Hernia in Focus: A Narrative Review of the Literature.

Pelvic herniation of the ureter through anatomical musculoskeletal foramina stands out as one of the rarest causes of ureteric obstruction. Historically, most cases have been documented as incidental intraoperative findings. The herniation of the ureter through the sciatic foramen presents as a particularly uncommon variant of this condition, distinguished by its potential to cause life-threatening sepsis or renal failure if not promptly recognized and treated. The diagnostic process remains challenging, attributed partly to the vague initial symptomatology and subtle radiological findings, and second, to the rarity of this condition. This challenge may be further compounded by the lack of a clear description of clinical features and pathways to raise clinician suspicion. In light of these considerations, we conducted this literature review to illuminate this unique cause of obstructive uropathy, aiming to delineate its clinical features and explore common diagnostic and treatment options.

Pheochromocytoma manifesting as cortical blindness secondary to PRES with associated TMA: a case report and literature review.

BACKGROUND: Pheochromocytomas are neoplasms originating from neuroectodermal chromaffin cells leading to excess catecholamine production. They are notorious for causing a triad of headaches, palpitations, and sweats. Though the Menard triad is one to be vigilant of, symptomatic presentation can vary immensely, hence the tumor earning the label "the great masquerader." CASE PRESENTATION: We report a case of pheochromocytoma initially presenting with cortical blindness secondary to posterior reversible encephalopathy syndrome and thrombotic microangiopathy from malignant hypertension. Our patient was seen in our facility less than a week prior to this manifestation and discharged after an unremarkable coronary ischemia work-up. In the outpatient setting, she had been prescribed multiple anti-hypertensives with remarkably elevated blood pressure throughout her hospitalization history. CONCLUSION: Pheochromocytoma presenting with malignant hypertension and hypertensive encephalopathy should be expected if left untreated; nonetheless, the precipitation of cortical blindness is rare in the literature. This case contributes an additional vignette to the growing literature revolving adrenal tumors and their symptomatic presentation along with complex management. It also serves to promote increased diagnostic suspicion among clinicians upon evaluating patients with refractory hypertension.

Prevalence and Clinician Recognition of Avoidant/Restrictive Food Intake Disorder in Patients With Inflammatory Bowel Disease.

BACKGROUND: Avoidant/restrictive food intake disorder (ARFID) is a newly described eating disorder. The aims of this study were to evaluate the prevalence of ARFID in patients with inflammatory bowel disease (IBD) and assess provider recognition of an eating disorder in these patients. METHODS: One hundred patients with IBD seen at the Mayo Clinic subspecialty IBD practice in Jacksonville, Florida were screened for ARFID. The diagnosis of ARFID was established using the Nine-Item Avoidant/Restrictive Food Intake Disorder Screen (NIAS) questionnaire. Providers also were asked their opinion of each participating patient's disease severity and whether they believed that the patient had an eating disorder. RESULTS: Of the 98 patients who completed the NIAS questionnaire, 10.2% scored above the clinical cutoff for ARFID. Clinician sensitivity in identifying an eating disorder was 0% and specificity was 96.5%. CONCLUSION: This pilot study suggests that patients with IBD are at risk for ARFID. Provider recognition of patients at risk for an eating disorder was low. Efforts to educate gastroenterology clinicians to identify and screen at-risk patients for ARFID and other eating disorders are needed.

Perioperative and long-term outcomes of utilizing donation after circulatory death liver grafts with macrosteatosis: A multicenter analysis.

BACKGROUND: Given the potentially additive risk from using donor livers that are both steatotic and from a donation after circulatory death (DCD) donor, there is a paucity of data on the outcome of DCD liver transplantation (LT) utilizing livers with macrosteatosis. METHODS: All DCD LT performed at Mayo Clinic-Florida, Mayo Clinic-Arizona, and Mayo Clinic-Rochester from 1999 to 2019 were included (N = 714). Recipients of DCD LT were divided into 3 groups: those with moderate macrosteatosis (30%-60%), mild macrosteatosis (5%-30%), and no steatosis (<5%). RESULTS: Patients with moderate macrosteatosis had a higher rate of postreperfusion syndrome (PRS; 53.9% vs 26.2%; P = .002), postreperfusion cardiac arrest (7.7% vs 0.3%; P < .001), primary nonfunction (PNF; 7.7% vs 1.0%; P = .003), early allograft dysfunction (EAD; 70.8% vs 45.6% and 8.3%; P = .02), and acute kidney injury (AKI; 39.1% vs 19.4%; P = .02) than patients with no steatosis. No difference in any of the perioperative complications was seen between the mild macrosteatosis and the no steatosis groups except for the rate of EAD (56.8% vs 45.6%; P = .04). No difference in ischemic cholangiopathy (IC), vascular thrombosis/stenosis or graft, and patient survival was seen between the 3 groups. CONCLUSION: DCD donors with mild macrosteatosis < 30% can be utilized with no increase in perioperative complications and similar patient and graft survival compared to DCD donors with no steatosis. When utilizing DCD donors with moderate macrosteatosis higher rates of PRS, PNF, postreperfusion cardiac arrest, EAD, and AKI should be anticipated.

Does Donor Allograft Microsteatosis Matter? Comparison of Outcomes in Liver Transplantation With a Propensity-Matched Cohort.

It has been suggested that microsteatosis does not negatively impact graft survival following liver transplantation (LT). The present study represents the largest series on donor livers with significant microsteatosis and investigates the impact of microsteatosis on perioperative factors such as postreperfusion syndrome (PRS), early allograft dysfunction (EAD), and postoperative renal dysfunction. Clinical outcomes of all patients undergoing LT with donor livers with isolated microsteatosis (≥30%; n = 239) between 2000 and 2017 were compared with a propensity score-matched cohort of patients undergoing LT with donor livers with no steatosis (n = 239). Patients in the microsteatosis group had a higher rate of PRS (33.1% versus 24.2%; P = 0.03), EAD (38.2% versus 23.0%; P < 0.001), and continuous renal replacement therapy (CRRT) requirement following LT (10.9% versus 3.6%; P = 0.002) than the no steatosis group. No difference in patient (P = 0.33) or graft survival (P = 0.18) was observed between the 2 groups. On multivariate regression, livers with microsteatosis had an increased risk of graft loss with retransplant recipients (hazard ratio [HR], 1.59; P < 0.001), increasing Model for End-Stage Liver Disease (MELD) score (HR, 1.13; P = 0.01), and organs from donation after circulatory death donors (HR, 1.46; P = 0.003). In conclusion, recipients of donor livers with significant microsteatosis are at an increased risk of PRS, EAD, and postoperative renal dysfunction requiring CRRT. Livers with significant microsteatosis should be avoided in retransplant recipients and in recipients with high biological MELD scores. Once appropriately selected recipients of these livers are able to overcome the initial perioperative implications of using these donor livers, longterm patient and graft survival is similar to recipients receiving grafts with no steatosis.
