BACKGROUND Cardiovascular disorders are common in HIV-1 infected persons in Africa and presentation is often insidious. Development of screening algorithms for cardiovascular disorders appropriate to a resource-constrained setting could facilitate timely referral. Cardiothoracic ratio (CTR) on chest radiograph (CXR) has been suggested as a potential screening tool but little is known about its ...

In our previous studies a twofold cardiomegaly associated with a proportional increase in cardiac DNA was found in rats subjected to a low-iron diet after weaning. To localize the newly synthesized DNA, control and anemic rats 24—34 days of age were given three intraperitoneal injections of Hthymidine (1 /Ac/g body weight; 22c/mM) at 2-hour intervals. The radioautographs were prepared from sect...

Hypertensinogenic potency and other effects of acetate salts of aldosterone (ALA) and deoxycorticosterone (DOCA) were evaluated in 50-day-old mononephrectomized and saline-drinking Sprague-Dawley CD male rats. The steroids were administered by continuous subcutaneous infusion in a dose of 100 microgram/24 hrs by means of Alzet osmotic minipumps implanted subcutaneously. Within 3 weeks of steroi...

Using self-determination theory (Deci & Ryan, 1985) as the theoretical framework, we examined potential antecedents of athlete burnout in 201 elite Canadian athletes (121 females, 80 males; mean age 22.9 years). Employing a cross-sectional design, our primary aims were to investigate the relationships between behavioural regulations and athlete burnout and to examine whether self-determined mot...

A female infant with generalized GM1-gangliosidosis differing in several aspects from previously reported cases is described. Clinically she is the first case to have cardiomegaly, unilateral congenitial dislocation of the hip and normal facial appearance. She had a higher residual leucocyte 13-galactosidase activity towards two synthetic substrates, namely p-nitrophenyl-f3-D-galactoside (PNP-1...

The varying clinicalfeatures and sequelae in Io patients sufferingfrom myocarditis after dengue and chikungunya fever caused by arboviruses are described. These patients had significantly raised antibody levels in the serum and gave a recent history of 'dengue-like' fever. Afew patients had afavourable outcome with disappearance of symptoms, improvement in the electrocardiogram, and no residual...

The description of familial cardiomegaly by Evans (1949) has thrown some light on the group of patients in whom cardiac enlargement, for which there appears to be no adequate clinical explanation, is the main physical finding. The purpose of this paper is to describe a family showing evidence of a cardiac abnormality affecting five ofnine siblings and one of their children. When the first membe...
