Mitral valve prolapse syndrome is a common clinical entity that may occur as an isolated condition or in association with other cardiovascular diseases. In this retrospective study, 41% (23/56) of the male patients with echocardiographically diagnosed mitral valve prolapse had an additional form of cardiovascular disease.
beta-Adrenoceptor blocking agents are important agents in the management of many cardiovascular problems. Multiple neuropsychiatric adverse reactions have been noted with their use. This article reviews these reactions and describes the case of a suspected propranolol-induced psychosis.
Since the introduction of penicillin in 1942, there have been only 11 culture-proven cases of gonococcal endocarditis in the English literature. Most patients are under 30 years of age and have no history of heart disease. The aortic valve is often involved and aortic regurgitation is common. The bacteriologic diagnosis can be difficult and may require more than six blood cultures and a long incubation period. Circulating immune complexes appear to be the cause of many of the extracardiac manifestations. The three new cases reported herein and review of the literature emphasize the distinctive features of gonococcal endocarditis.
