Diagnostic and therapeutic considerations for "mycotic" cerebral aneurysms: 2 case reports and review of the literature.

Objective: Cerebral aneurysms of an infectious etiology, so-called "mycotic" aneurysms, are rare neurovascular pathologies. Primary treatment may be targeted on the aneurysm, but care has to be driven by the underlying pathology to prevent an often fatal clinical course with a mortality rate reaching 90%. 2 case reports are presented, and the diagnostic and therapeutic issues outlined by reviewing the literature.

Renal renin-angiotensin system activity in naturally reared and cross-fostered spontaneously hypertensive rats.

Background: Young (4 week) spontaneously hypertensive rats (SHR) exhibit greater renal responses to angiotensin II (Ang II) than normotensive Wistar Kyoto (WKY) rats. SHR pups cross-fostering to a WKY dam at birth (SHRX) are less sensitive to Ang II and have lower adult blood pressure. The aim of this study was to compare renal renin-angiotensin system activity in young naturally reared and cross-fostered SHR pups.

The glomerulo-tubular junction: a target in renal diseases.

Both global and segmental glomerulopathies may damage specific areas of the renal glomerulus. Diseases associated with glomerular hyperperfusion cause lesions at the vascular pole, while diseases associated with proteinuria often damage the tubular pole. Atubular glomeruli are now known to be plentiful in a variety of common renal diseases.

Ectopic thyroid tissue on the ascending aorta: an operative finding.

We describe a case of benign ectopic thyroid tissue found attached to the ascending aorta at operation.
