Haemorrhagic shock secondary to a diffuse ulcerative enteritis after Ipilimumab and Nivolumab treatment for metastatic melanoma: a case report.

Ann Palliat Med 2021 Jun 2. Epub 2021 Jun 2.

Université de Paris, Department of Gastroenterology, AP-HP Hôpital Saint Louis, Paris, France.

We provide a unique case of haemorrhagic shock complicating a corticosteroid-resistant diffuse ulcerative enteritis in a patient treated with a combination of an anti CTLA-4 and an anti PD-1 for metastatic melanoma. Immunotherapy has changed the perspective for the management of patients with metastatic melanoma but are also responsible for digestive complications mainly represented by immunomediated colitis. Digestive bleeding is common in patients with extensive colonic lesions but has never been described in enteritis independent of colitis. Read More

SLC26A6-selective inhibitor identified in a small-molecule screen blocks fluid absorption in small intestine.

JCI Insight 2021 Jun 8;6(11). Epub 2021 Jun 8.

Departments of Medicine and Physiology, University of California, San Francisco, San Francisco, California, USA.

SLC26A6 (also known as putative anion transporter 1 [PAT1]) is a Cl-/HCO3- exchanger expressed at the luminal membrane of enterocytes where it facilitates intestinal Cl- and fluid absorption. Here, high-throughput screening of 50,000 synthetic small molecules in cells expressing PAT1 and a halide-sensing fluorescent protein identified several classes of inhibitors. The most potent compound, the pyrazolo-pyrido-pyrimidinone PAT1inh-B01, fully inhibited PAT1-mediated anion exchange (IC50 ~350 nM), without inhibition of the related intestinal transporter SLC26A3 (also known as DRA).

A Fetus with Imperforate Anus Developing Pulmonary Hypoplasia Triggered by Transient Urethral Obstruction.

Case Rep Obstet Gynecol 2021 13;2021:9950578. Epub 2021 May 13.

Department of Obstetrics and Gynecology, Faculty of Medicine, The University of Tokyo, 7-3-1 Hongo, Bunkyo-ku, Tokyo 113-8655, Japan.

Pulmonary hypoplasia is a rare entity in a fetus with imperforate anus. The fetus was diagnosed with high-type imperforate anus with rectourethral fistula based on the dilated fetal bowel and the presence of bowel calcification at 19 weeks of gestation. As gestation advanced, fetal ultrasonography demonstrated development of pulmonary hypoplasia, progressive bowel dilation, and persistent oligohydramnios from 28 weeks of gestation despite a fluid-filled bladder without hydroureter or hydronephrosis.

Long-term response on letrozole for gastric cancer: A case report.

Medicine (Baltimore) 2021 May;100(21):e26146

Department of Surgery, Yaizu City Hospital.

Rationale: Hormone therapies, particularly those targeting estrogen and its receptors, are a key treatment modality for patients with estrogen receptor (ER)-positive breast or ovarian cancer. Some gastric cancers (GCs) express ERs, and preclinical studies suggest the potential of estrogen-targeting hormone therapy on GC; however, the clinical relevance of this hormone therapy on GC treatment has not been well elucidated.

Patient Concerns: An 80-year-old female was admitted to our department with hypogastric pain and vomiting. Read More
