Black Urine and Methemoglobinemia in the Setting of Sepsis Due to Clostridium Perfringens.

Clostridium Perfringens is an anaerobic gram-positive bacillus able to produce different types of toxins and can cause septicemia. The mechanism is through translocation from a previously colonized gastrointestinal or genital tract. Massive intravascular hemolysis induced by this bacterium is a rare presentation reported in only 7% to 15% of cases of Clostridium Perfringens bacteremia with a mortality rate reaching 90%.

Primary congenital anomalies of the coronary arteries and relation to atherosclerosis: an angiographic study in Lebanon.

Background: Most coronary artery anomalies are congenital in origin. This study angiographically determined the prevalence of different forms of anomalous aortic origins of coronary anomalies and their anatomic variation in a selected adult Lebanese population. Correlation between these anomalies and stenotic coronary atherosclerotic disease was also investigated.
