Resternotomy for a retrosternal cardiac pseudoaneurysm in a 1.5-year- old child: a case report.

Cardiac pseudoaneurysm is a contained rupture of the myocardium that can occur after cardiac surgery, chest trauma, and endocarditis. The wall of the pseudoaneurysm consists of fibrous tissue and lacks the structural elements found in a normal cardiac wall, and it is contained by the pericardial adhesions or the epicardial wall. Early surgery is recommended even for asymptomatic patients due to the propensity for rupture and fatal outcome.

Ascites as first presentation of ventriculo-peritoneal shunt infection in a neonate.

Infection is a common complication of ventriculoperitoneal shunts, and ascites is one of the rare manifestations of shunt infection. We report a neonate in whom shunt infection is presented only by ascites. The causative organism, coagulase negative staphylococci, was detected only in the cerebrospinal fluid although peritoneal fluid analysis was consistent with infection.

Central fever due to hypothalamic lesion in a patient with tuberculous meningitis.

Abnormalities of body temperature are perhaps the most common features in many systemic pathologic processes. Such pathologic alterations are nearly always the result of extrinsic factors (for example, systemic pyrogens) which affect the hypothalamic thermoregulatory center by way of circulatory system. Much less common is alterations in temperature regulation resulting from intrinsic lesions of the thermoregulatory center in the hypothalamus.
