Intestinal Spirochetes Associated With Asymptomatic COVID-19 Infection.

A 60-year-old, human immunodeficiency virus (HIV)-negative, homosexual male presented to our colorectal clinic with abdominal pain for three weeks followed by persistent watery diarrhea refractory to loperamide. He had no history of recent travel, no known infectious contacts, and his last colonoscopy nine years prior was within normal limits. After one episode of hematochezia, computed tomography of the abdomen/pelvis was performed demonstrating colitis and coronavirus disease 2019 (COVID-19)-related changes to the lung bases.

Malignant Degeneration to Leiomyosarcoma of the Anorectal Junction Invading the Prostate.

While colonic leiomyomas are common, leiomyosarcomas of the GI tract are rare. Increased mitotic rate, as well as lymph node involvement, portend a worse prognosis in leiomyosarcomas. They can arise anywhere along the GI tract, but anal canal occurrence is extremely rare.

Total Robotic Biliopancreatic Diversion with Duodenal Switch Technique.

The use of robotic bariatric surgery has increased significantly since its advent in 1999. Its utility and safety has been demonstrated in the literature for all bariatric procedures, including most recently the biliopancreatic diversion with duodenal switch (BPDDS). The robotic-assisted biliopancreatic diversion with duodenal switch (RBPDDS) was first described by Sudan et al.

The monocyte to macrophage transition in the murine sterile wound.

The origin of wound repair macrophages is incompletely defined and was examined here in sterile wounds using the subcutaneous polyvinyl alcohol sponge implantation model in mice. Phenotypic analysis identified F4/80(+)Ly6C(hi)CD64(+)MerTK(-) monocytes and F4/80(+)Ly6C(low)CD64(+)MerTK(+) macrophages in the wound. Circulating monocytes were the precursors of inflammatory Ly6C(hi) wound monocytes.

Glassware washers: cleaning glassware and implements used in compounding, part 2.

Compounding with glassware and utensils that are contaminated with drug residues or pyrogens is a recipe for disaster. Using a powerful glassware washer, which can ensure that compounding implements are clean and free of contaminants, may be a worthwhile investment for compounding pharmacies in which the volume of preparations justifies the washer's cost. A glassware washer provides cleaning superior to that of residential or commercial dishwashers and offers other advantages that range from reproducible cycle parameters to programs that can be configured for specific cleaning needs to the ability to provide a purified-water rinse.
