ABSTRACT
PURPOSE--To analyze the clinical, laboratory and pathological aspects of 20 cases of infectious endocarditis (IE) who died. The authors compared patients with diagnosis before death of IE and those with diagnosis was made after autopsy. METHODS--Twenty patients who died with IE between April 1982 and November 1991 were studied. We looked for the clinical aspects (fever, cardiac murmurs, anemia, splenomegaly, embolic events and skin manifestation), laboratory aspects (hemocultures), echocardiographic and anatomopathologic features (valvar vegetations events and embolic accidents founded at autopsy). The sample was divided in two sub-groups: A--with clinical diagnosis of IE before and B--without diagnosis before death. RESULTS--Group A--9 patients aged 8-58 years, 3 men, all them with cardiac murmurs, fever and anemia, 5 with splenomegaly. Hemocultures were done in 7 patients and positive in 1. Echocardiogram with valvar vegetation were found in 4 out of 5 patients (80 per cent positive). At autopsy mitral valve vegetation were present in 7, aortic 3, tricuspid 3. One patient showed the exposure of three valves and two of 2 valves. Embolic events were found in 4. Group B--11 patients most of them older then 50 years (54.5 per cent) (p < 0.05) 5 men, all them presented fever and anemia. Cardiac murmurs in 6 (54 per cent) and none with splenomegaly. In one case hemoculture and echocardiogram, were done and were negative. Anatopathologic study showed compromise of mitral valve in 5, aortic 4, tricuspid 2, pulmonary 1. Two patients had 2 valves compromised. In one case a mural vegetation (right atrium) was found. Embolic events were present in 2 cases. CONCLUSION--In group B a significant number of patients (p < 0.05) were older than 50 years and presented his symptoms as an acute illness. We concluded that older patients with compromised general state and fever with or without embolic events IE must be remember

PURPOSE--To characterize the occurrence of bacteremia during delivery and to verify the necessity of prophylaxis against infective endocarditis. METHODS--The authors collected hemoculture of 100 women, 15,30 and 45 minutes after delivery. The data were collected from May 1992 until May 1993. The positive hemocultures were followed by antibiogram. RESULTS--Seven hemocultures were positive: six for Staphylococcus, one for Candida sp, Penicilium sp, Clandosporum sp and Aspergillus sp that were found in association. Four patients had prematures amniorrhexis, longer than 6 hours before delivery (p < 0.05). Six patients had labor longer than 6 hours after admission (p < 0.05). The authors did not observe differences related to vaginal delivery with or without forceps or cesarean section. The samples were all sensible to cefalotin at the antibiogram. CONCLUSION--Labor and delivery is a high risk procedure for bacteremia and so for ineffective endocarditis in susceptible patients. The statistical analysis recognize as risk factors labor longer than 6 hours inside the hospital and premature amniorrhexis. We propose the use of intravenous cefalotin 1g 60 minutes before expulsion and repeated 6 and 12 hours later
