Celiac disease (CeD) is a chronic, lifelong, multifactorial, polygenic, and autoimmune disorder, characteristically triggered by exposure to the exogenous factor "gluten" in genetically predisposed individuals, with resulting duodenal inflammation and enteropathy, as well as heterogeneous multisystemic and extraintestinal manifestations. The immunopathogenesis of CeD is complex, favored by a peculiar human leukocyte antigen (HLA) genetic predisposition, leading to gluten presentation by antigen-presenting cells to CD4+ T helper (Th) cells, T cell-B cell interactions, and production of specific antibodies, resulting in the immune-mediated killing of enterocytes and, macroscopically, in duodenal inflammation. Here, the most relevant correlations between cellular and molecular aspects and clinical manifestations of this complex disease are reviewed, with final considerations on nutritional aspects for disease management.

: Bouveret syndrome, a rare and often underdiagnosed variant of gallstone ileus, is characterized by the presence of a large gallstone impacted in the proximal duodenum, resulting in significant gastric outlet obstruction and aerobilia. Early identification of Bouveret syndrome is crucial for developing an appropriate surgical strategy. : A 76-year-old female underwent a contrast-enhanced abdominal CT scan, which revealed a cholecysto-duodenal fistula with a 3.

Background: Prepancreatic postduodenal portal vein (PPPV) is a rare anatomic variant where the portal vein (PV) runs anterior to the pancreas and posterior to the duodenum. Only 20 cases of PPPV, all in adults, have been reported in literature. We report the first case of PPPV in a pediatric patient discovered intraoperatively during total pancreatectomy with islet autotransplantation (TPIAT) and the third known case in which the PPPV could be isolated intraoperatively.

Despite exhibiting normal gastrointestinal mucosa upon endoscopy, biopsy analysis revealed chronic gastritis accompanied by the presence of Sarcina ventriculi in a tetrad arrangement across the stomach, duodenum, and distal esophagus. Interestingly, immunohistochemistry (IHC) staining targeting the Helicobacter pylori organism (H.

Type 2 diabetes mellitus (T2DM) is marked by chronic hyperglycemia, gradually worsening β-cell failure, and insulin resistance. Glucotoxicity and oxidative stress cause β-cell failure by increasing reactive oxygen species (ROS) production, impairing insulin secretion, and disrupting transcription factors such as pancreatic and duodenal homeobox 1 (PDX-1) and musculoaponeurotic fibrosarcoma oncogene family A (MafA). Cluster determinant 36 (CD36), an essential glycoprotein responsible for fatty acid uptake, exacerbates oxidative stress and induces the apoptosis of β-cells under hyperglycemic conditions through pathways involving ceramide, thioredoxin-interacting protein (TXNIP), and Rac1-nicotinamide adenine dinucleotide phosphate oxidase (NOX)-mediated redoxosome formation.
