Gastric Non-Hodgkin Lymphoma in a -Infected Patient.

Primary gastric diffuse large B-cell lymphoma (PG-DLBCL) is a rare gastric malignant neoplasm. While the association between infection and gastric mucosa-assisted lymphoid tissue lymphoma is well established, data supporting its association with DLBCL are less robust. Here we present a rare case of PG-DLBCL diagnosed with .

Lumen-Apposing Metal Stent Used to Treat Malignant Esophageal Stricture.

Malignant esophageal strictures often require stent placement to alleviate dysphagia and improve quality of life. We present a novel application of a lumen-apposing metal stent to bypass a malignant esophageal stricture in the setting of altered gastric anatomy.

Migration of a Lumen-Apposing Metal Stent into the Colon.

The introduction of lumen-apposing metal stents (LAMS) has been an important development in the management of pancreatic fluid collections. Stent migration out of pancreatic fluid collections into the stomach has been reported, despite the special anti-migratory design of the bi-flanged stent. Data on stent migration rates remain sparse, with some studies suggesting a migration rate of 3.

Mincle suppresses Toll-like receptor 4 activation.

Regulation of Toll-like receptor responses is critical for limiting tissue injury and autoimmunity in both sepsis and sterile inflammation. We found that Mincle, a C-type lectin receptor, regulates proinflammatory Toll-like receptor 4 signaling. Specifically, Mincle ligation diminishes Toll-like receptor 4-mediated inflammation, whereas Mincle deletion or knockdown results in marked hyperresponsiveness to lipopolysaccharide in vitro, as well as overwhelming lipopolysaccharide-mediated inflammation in vivo.

TGF-β Blockade Reduces Mortality and Metabolic Changes in a Validated Murine Model of Pancreatic Cancer Cachexia.

Cancer cachexia is a debilitating condition characterized by a combination of anorexia, muscle wasting, weight loss, and malnutrition. This condition affects an overwhelming majority of patients with pancreatic cancer and is a primary cause of cancer-related death. However, few, if any, effective therapies exist for both treatment and prevention of this syndrome.

An easily missed diagnosis: flank pain and nutcracker syndrome.

A 27-year-old woman presented to her primary care doctor's office with left flank pain. CT of the abdomen showed an isolated left renal vein thrombus. The clot was initially attributed to her oral contraceptive use; however, closer inspection of CT images revealed nutcracker phenomenon (compression of the renal vein between the superior mesenteric artery and abdominal aorta).
