Wischnewski Spots in a Case of Hyperosmolar Hyperglycemic State.

Wischnewski spots were first described as a common finding in gastric mucosa of decedents exposed to hypothermic environmental conditions. In recent literature, they were also reported in cases of diabetic ketoacidosis, pancreatitis, and fatal burns. Although Wischnewski spots are not specific to cases of hypothermia, we present a case that further supports this contention.

Deaths Associated With Community Donation Bins: A Ten-Year Retrospective Review Describing Five Cases in British Columbia and Ontario.

Introduction: Community donation bins have become more common in the urban setting over the past several years. Many nonprofit organizations use these sturdy metal enclosures for unobserved collection of various donated items such as clothing, books, and household items. Although the donated items are often of low individual value, donation bins may become a target of individuals in low socioeconomic situations seeking desired items for personal use or resale, or for personal shelter within the bin.

CPR-associated right ventricular rupture in the setting of pulmonary embolism.

Cardiopulmonary resuscitation (CPR) is an inherently traumatic procedure. Successful resuscitations are often complicated by iatrogenic injuries to structures of the neck, thorax, or abdomen. Rib and sternal fractures are the most frequently induced injuries.

Mycobacterium tuberculosis employs Cpn60.2 as an adhesin that binds CD43 on the macrophage surface.

CD43 is a large sialylated glycoprotein found on the surface of haematopoietic cells and has been previously shown to be necessary for efficient macrophage binding and immunological responsiveness to Mycobacterium tuberculosis. Using capsular material from M. tuberculosis and recombinant CD43-Fc, we have employed affinity chromatography to show that Cpn60.

Mycobacterium tuberculosis Cpn60.2 and DnaK are located on the bacterial surface, where Cpn60.2 facilitates efficient bacterial association with macrophages.

Mycobacterium tuberculosis, the causative agent of tuberculosis, initially contacts host cells with elements of its outer cell wall, or capsule. We have shown that capsular material from the surface of M. tuberculosis competitively inhibits the nonopsonic binding of whole M.
