We report a physical assault on a 25-year-old male medical resident who was on-call in the emergency room. Causes of assault on physicians as well as how they can be avoided are discussed

An in vitro study was performed to modify the conventional mock circulatory loop to evaluate the effects of different prosthetic heart valve occluders on normal and sickle red blood cell hemolysis. Under the same hemodynamic pressure and flow condition, the hemolytic percentage monotonically increased with the heart rates for all types of occluders. Compared to the caged-ball and unileaflet occluders, the bileaflet prosthetic heart valve occluder exhibited the lowest hemolytic level for all heart rates tested for normal and sickle red blood cells. For sickle red blood cells, the data indicate that hemolytic levels are influenced by the blood type rather than the design of the valve occluder. Caged-ball and unileaflet valve occluders demonstrated inconsistent hemolytic behavior over the range of tested heart rates; thus, the merit of one type of occluder over the other has not been established. The results also indicate that homozygote sickle cells are more susceptible to heart valve occluders than heterozygote cells

CONGENITAL pericardial cysts constitute 7% of all mediastinal masses. Since acquired cysts and their complications, such as spontaneous rupture and presentation with hemoptysis, are rarely reported, we elect to report the present case of pericardial cyst that had a number of unusual features, notably the location of the cyst, gross and microscopic pathology, and clinical symptomatology

A retrospective review of 65 consecutive patient charts with a diagnosis of atrial fibrillation was performed in order to study the prevalence of associated underlying disease. Rheumatic heart disease was noted in 31%, cardiomyopathy in 17% and arteriosclerotic heart disease in 12%. Atrial fibrillation was paroxysmal in 23 patients [35%] and sustained in 42 [65%] of the patients. Increased left atrial size was an important predictor of sustained atrial fibrillation
