Fatal community-acquired Bacillus cereus pneumonia in an immunocompetent adult man: a case report.

Background: Bacillus cereus is a gram-positive rod bacterium that is responsible for food poisoning. It is naturally widely distributed, and thus often contaminates cultures. Although it is rarely considered responsible, it can cause serious infections under certain conditions.

Contrasting genetic structure of closely related giant water bugs: phylogeography of Appasus japonicus and Appasus major (Insecta: Heteroptera, Belostomatidae).

Appasus japonicus and A. major, two belostomatid species of the giant water bug found in parts of East Asia, have very similar morphological characteristics and ecological niches, and also overlapping habitats. However, the results of our previous published study utilizing molecular phylogenetic analyses of mitochondrial and nuclear DNA revealed extensive genetic differences, which indicated that the possibility of inter-specific hybridization was extremely unlikely.

Massive right pleural effusion and ascites caused by a primary constrictive pericardial band.

A previously healthy 57-year-old woman with peripheral edema and exertional dyspnea had diminished right breath sounds and edema of both legs. Chest radiography showed massive right pleural effusion, and abdominal computed tomography showed ascites. During cardiac catheterization, pressure curves of both ventricles showed "dip-and-plateau" patterns.

Removal of a splenic artery with a large aneurysm adhered to the pancreas without pancreatectomy: report of a case.

Splenic artery aneurysms account for about 60% of all visceral aneurysms. The treatment include surgical procedures that sometimes require pancreatectomy. This report describes the case of a 64-year-old woman who had multiple splenic artery aneurysms with various visceral artery dilatations.
