Biliary complications following liver transplant are common. Endoscopic retrograde cholangiopancreatography (ERCP) and magnetic resonance cholangiopancreatography (MRCP) are the main techniques used to diagnose and treat biliary complications; however, these techniques have limits to the depth of visualization. In this report, we present five cases of orthotopic liver transplant patients with biliary complications that underwent ERCP- or MRCP-guided cholangioscopy with the SpyGlass™ DS Direct Visualization System (SDDVS). The SDDVS allowed for the visualization of the morphological characteristics of biliary strictures, and images collected using the SDDVS allowed for four of the cases to be treated endoscopically. Our findings suggest that cholangioscopy with the SDDVS is a promising method to guide the endoscopic treatment of biliary complications after liver transplantation.Amelogenesis imperfecta (AI) represents rare tooth anomalies that affect the quality and/or quantity of the enamel. Clinical phenotypes display a wide spectrum, ranging from mild color changes to severe structural alterations with daily pain. However, all affect the quality of life because of mechanical, psychological, esthetic, and/or social repercussions. Several gene mutations have been linked to AI as a nonsyndromic (isolated) phenotype or a wider syndrome. This case report aimed to present a family with dental structure anomalies followed up in the dental department of the Louis Mourier Hospital (APHP, France) for their extremely poor dental condition. The proband and his mother were clinically diagnosed with AI, and genetic analysis revealed an already described variant in DLX3. Then, the family was further examined for tricho-dento-osseous syndrome. This report illustrates the challenge of diagnosing dental structure anomalies, specifically AI, in adults and highlights the need for an accurate and accessible molecular diagnosis for those anomalies to discriminate between isolated and syndromic pathologies.Gardner's syndrome is an autosomal dominant disease caused by a mutation in the APC gene with 20-30% of cases presenting de novo. This entity is a variant of familial adenomatous polyposis, with a prevalence of 3/100,000 habitants. It may present as early as 2 months of age with a variety of both colonic and extracolonic symptoms. We report a case of a 21-year-old man, without any known family history, presenting with microcytic hypochromic anemia and constitutional symptoms for two months. Ultimately, after the etiological study, Gardner syndrome diagnosis was established as an index primary familiar case. Gardner syndrome is a clinical challenge which requires a prompt suspicion in order to reach its diagnosis. Given the malignant evolution of adenomas in 100% of untreated patients, early identification of extraintestinal manifestations (identifiable prior to colonic symptoms) is of the essence. A consequent endoscopic study to confirm gastrointestinal involvement is essential for a more favorable prognosis.Addisonian crisis is the life-threatening acute manifestation of adrenal insufficiency due to absolute or relative glucocorticoid deficiency. Adrenal haemorrhage is a rare condition of unknown incidence with the risk of adrenal insufficiency and death, not uncommonly first being diagnosed on the pathologists table. We report the case of a 68-year-old female patient with respiratory tract infection suffering acute life-threatening adrenal insufficiency caused by bilateral adrenal haemorrhages following orthopedic surgery while taking anticoagulation therapy. The patient rapidly deteriorated with hypotension, showing how important it is to consider a possible Addisonian crisis when this scenario occurs, especially with precipitating factors such as anticoagulant therapy, sepsis, or surgery.Euglycemic ketoacidosis is a recognised side effect secondary to sodium-glucose cotransporter 2 inhibitor use in the treatment of type 2 diabetes mellitus; however, there is scarce evidence to suggest whether preexisting comorbid conditions contribute to the development of this potentially life-threatening complication. We describe a case of euglycemic ketoacidosis in a patient with type 2 diabetes mellitus in the context of empagliflozin use after a recent diagnosis of metastatic lung adenocarcinoma. The diagnosis was complicated by a pulmonary embolism and hospital-acquired pneumonia, and was subsequently established after an anion-gap metabolic acidosis was identified on arterial blood gas and serum ketone measurement. The patient required admission to the intensive care unit for fluid resuscitation and regular intravenous insulin to ensure resolution of acidosis and maintenance of normoglycaemia. The patient was discharged to home for outpatient single-agent pembrolizumab for treatment of his lung adenocarcinoma. This article highlights the importance or awareness of oral hypoglycaemic medications and their side effects, along with providing further evidence for the potential contribution of malignancy to the development of euglycemic ketoacidosis in a patient with type 2 diabetes mellitus.Von Hippel-Lindau disease is an autosomal dominant inherited syndrome predisposing to a variety of highly vascularised tumors in different organs. Although bilateral pheochromocytoma was reported in patients with von Hippel-Lindau disease, the coexistence of primary hyperparathyroidism is not a common condition. We report an observation of a primary hyperparathyroidism secondary to an ectopic secretion of intact parathyroid hormone in a 17-year-old girl with von Hippel-Lindau disease and bilateral pheochromocytoma. She presented with a newly diagnosed diabetes mellitus and a severe arterial hypertension. Blood tests disclosed hypercalcemia with increased intact PTH level. Cervical ultrasound and sestamibi scintigraphy were normal. Twenty-four-hour urinary normetanephrine level was highly elevated pointing to a catecholamine-secreting tumor. [https://www.selleckchem.com/products/pf-3644022.html Selleckchem PF-3644022] The abdominal computed tomography showed bilateral adrenal masses. MIBG scintigraphy exhibited a high accumulation of the tracer in both adrenal tumors. Genetic testing revealed a mutation of the VHL gene.
