This case report describes a 20-year-old woman who developed acute group B streptococcal endocarditis after a saline-induced abortion. She was admitted 2 weeks after an uncomplicated saline-induced abortion for a 16-week pregnancy with a 1-week history of fever, headaches, dizziness, and shortness of breath. The patient showed poor response to antibiotic therapies (initially to nafcillin and gentamicin and then to aqueous penicillin G). 6 to 6 blood cultures after hospital admission showed group B streptococcus which was penicillin sensitive by tetracycline resistant. On Day 3 of admission, a pericardial friction rub was noted and repeat chest x-rays showed marked enlargement of the cardiac shadow. Surgery was performed, and the mitral valve posterior leaflet was necrotic, and a mitral valve prosthesis was placed and an aortic embolectomy was performed. Postoperatively, she was treated with an additional 6-week course of intravenous penicillin, and subsequently, she has remained asymptomatic after 6 months. An addendum to this report, which was only the 2nd such report of endocarditis after saline abortion, describes another case of group B streptococcal endocarditis in a drug abuser after a saline-induced abortion. She required tricuspid valvulectomy and is slowly improving postoperatively.

Forty patients with acquired immunodeficiency syndrome (AIDS), 70% of whom were intravenous drug abusers (IVDAs), were seen over a 20-month period (July 1, 1981, through Feb 28, 1983). Most of the patients came from two inner-city sections of New York City and from nearby correctional facilities. Eighty-five percent of the patients were black or Hispanic; only 15% were white. Unique features of AIDS in this mostly heterosexual population were the high incidence of opportunistic infections (90% of the patients), the low incidence of Kaposi's sarcoma (10%), and the high mortality rate (34% died during initial hospitalization, 74% after one year of follow-up). Tuberculosis occurred in 10% of cases, preceding other opportunistic infections by four to 24 months. We found that AIDS was a common disease among inpatient IVDAs, and in one of the participating hospitals, its incidence was similar to that of infective endocarditis. Acquired immunodeficiency syndrome should be considered as the underlying illness in all IVDAs with oral thrush, shortness of breath, pneumonia, or extra-pulmonary tuberculosis.

Acute valvular obstruction caused by vegetation is a rare complication infective endocarditis. To our knowledge, only 9 cases and an autopsy case by Roberts have been reported since 1967. A 46-year-old man admitted with a chief complaint of pyrexia for 2 months duration. Within 24 hours of admission, the patient noticed of increased shortness of breath. Physical examination and the chest X-ray confirmed the pulmonary edema. An echocardiogram revealed a huge echogenic mass that was adherent to the mitral leaflet and obstructed the orifice completely. Soon after the patient fell into cardiogenic shock, an emergency mitral valve replacement was undertaken. At operation, multiple verrucae arising from the entire mitral leaflet was seen to occlude the orifice. The vegetation was excised and replaced with a # 25 Omnicarbon prosthesis. Postoperatively, the patient developed multiple organ failure caused by cardiogenic and septic shock which responded well to intensive medical treatment consisting of hemodialysis and continuous arteriovenous hemofiltration. Angiographically, a mycotic aneurysm in the left radial artery was found on the 18th postoperative day. After extirpation of the infective focuses, the postoperative course had stabilized. Mitral obstruction due to infective endocarditis is a fatal disease. Prompt diagnosis with echocardiogram and an emergency surgery should be undertaken to save the patient.

A 63-year-old man with cough and shortness of breath was diagnosed to have active infective endocarditis resulting in acute pulmonary edema with aortic regurgitation caused by a huge vegetation on the noncoronary cusp and left ventricular-right atrial (LV-RA) communication which were demonstrated by the echocardiogram and color doppler method. The LV-RA communication located at the atrioventricular portion of the membranous septum was closed with GoreTex patch through the right atrium combined with the aortic valve replacement with a bileaflet mechanical valve in emergency. The bacteriological studies demonstrated staphylococcus epidermidis. The postoperative course was uneventful and the patient is now on regular duty two years after surgery.

A case of mitral valve aneurysm associated with infective endocarditis is reported. The patient is a sixty-four year old male suffering from shortness of breath under slight exertion. He has been febrile since receiving dental treatment five months ago. The patient came to the hospital due to a continuous fever above 39 degrees C. Hematological studies suggested inflammation, and an echocardiogram revealed moderate dilatation of the left atrium, mild MR, and moderate AR. At the time of the operation, a protuberant lesion, shaped like a dome and having a size of 10 x 12 mm in diameter was found at the anterior mitral leaflet toward the left atrium. The resected specimen of the saccular lesion had a smooth surface, and the ceiling of the aneurysm was extremely thin. Microscopic study showed that the inner cavity of the lesion was covered by endothelial cells. In addition, there was granulomatous degeneration with neo-vascularization. The inferior surface of the resected valve tissue and chorda was characterized by active inflammation associated with the assembly of neutrophils and colony formation of gram-positive cocci. It was concluded that the mitral valve aneurysm was caused by weakened tissue of the anterior mitral leaflet due to sibilant inflammatory change, which resulted in protuberance of the leaflet toward the left atrium caused by left ventricular pressure.

A case of successfully treated fungal tricuspid infective endocarditis with repeated pulmonary embolism is reported. A 60-year-old man had received along term intravenous hyperalimentation for the treatment of the complication after hepatopancreatoduodenectomy, associated with Candida sepsis. He was once discharged, successfully treated with antifungal agents. But he was readmitted to our hospital due to fever, cough and chest pain. Blood culture revealed Candida tropicalis. Pulmonary scintigraphy and angiography revealed multiple infarcts of the right lung, and echocardiography showed vegetation on the tricuspid valve. Because of exacerbation of shortness of breath, tricuspid valvuloplasty and thromboembolectomy in the pulmonary arteries was performed. Postoperative course was uneventful and he had a marked improvement of dyspnea after operation.

Cigarette smoking, hypertension, hypercholesterolemia, and periodontal disease have been established as major risk factors for cardiovascular disease. Dentists and physicians should work aggressively to educate periodontitis patients about this relationship in an effort to improve the quality of health and contribute to their long-term survival. Blood pressure should be checked at the initial dental visit and at each subsequent visit in patients whose blood pressure is found to be high and/or has a history of hypertension. Dental and medical assistants should receive in-service training to assure competency in measuring blood pressures. All staff should be certified in basic cardiopulmonary resuscitation. Emergency protocol procedures should be in writing and rehearsed regularly. Patients should take their blood pressure medication as usual on the day of the dental procedure. It is helpful for the patients to bring all medications to the office for review at the time of the dental procedure. Good communication should be established between the dentist and physician to maximize good dental and physical health. Because the patient with periodontal disease is at an increased risk for cardiovascular disease, a standardized form should be developed for the convenient exchange of vital information, including but not limited to: blood pressure, medications, allergies, medical conditions and pertinent highlights of dental procedures. Minimize stress in patients with coronary artery disease. This includes providing solid local anesthesia, avoidance of intravascular medication injections, and encouraging relaxation techniques. Antibiotic prophylaxis is indicated in patients with valvular heart disease but does not guarantee the prevention of endocarditis. These patients should be alerted to monitor any symptoms such as fever, chills or shortness of breath. It has also been documented that toothbrushing, flossing and home plaque removers can cause transient bacteremia in periodontal patients. Epinephrine use should be avoided or utilized cautiously in patients with pacemakers or automatic defibrillator devices because of the possibility of refractory arrhythmia. Consultation with patient's cardiologist is advised. Anticoagulation with coumadin is not a contraindication to dental procedures. The prothrombin time or international normalized ratio laboratory values should be checked on the day of the procedure to assure that it is in an acceptable range. Aspirin therapy is not a problem unless the patient is on very high doses for severe arthritis. Continuing medical and dental education credits should emphasize cross-training in both areas to insure comprehensive treatment of the patient with periodontal disease. Smoking cessation, regular exercise, a low-fat diet and good dental hygiene contribute to a healthy cardiovascular system. Patients should understand as best we know the relationship between periodontal and cardiovascular disease to afford them an opportunity to improve their overall dental and physical health.

The aim of this study was to report the experience with infective endocarditis over the past decade, describe the changing clinical and epidemiological features of the disease, and attempt to determine the optimal number of blood culture sets required for diagnosis. All cases diagnosed during a 10-year period were reviewed clinically and microbiologically. In addition, a retrospective assessment of blood culture data was performed. From the period 1990-1999, 108 cases that met the von Reyn or Duke's criteria were recorded. The major underlying cardiac condition was the presence of a prosthetic valve ( n=33 patients, 31%). Among patients with native valves, nonrheumatic valvular heart disease of the elderly was the most common underlying factor ( n=19 patients, 25%). Overall, 13 patients (11%) died. Predictors on admission for increased mortality were shortness of breath, age >60 years, time to defervescence, erythrocyturia, hemoglobin level <10 g/dl, and leukocytosis >15,000 (all P<0.05). Analysis of blood culture data showed that the diagnostic yield among groups from whom either only one or more than six blood culture sets were drawn was reduced compared with that among groups from whom between two and five culture sets had been taken. The outcome of endocarditis in this series from a community hospital was much more favorable compared with that reported in surveys from large tertiary centers. Moreover, obtaining more than two or three blood cultures is neither helpful nor cost-effective in the initial assessment of patients with suspected endocarditis.

Piercing invades subcutaneous areas and has a high potential for infectious complications. The number of case reports of endocarditis associated with piercing is increasing. We studied a 25-year-old man with a pierced tongue, who arrived at Memorial Health University Medical Center with fever, chills, rigors, and shortness of breath of 6 days' duration and had an aortic valvuloplasty for correction of congenital aortic stenosis.

The knowledge pertaining to mitral valve prolapse is mainly based on studies in adults. In this study, the clinical profile as described in adults was compared with that found in children up to the age of 13 years. Forty-five children with echocardiographic-proven mitral valve prolapse and who met the inclusion criteria were included in the study. The male:female ratio in this study was 1:1.37 and was not statistically significantly different from reported ratios. Most of the children were asymptomatic. Twenty-one of the 31 patients referred from outside the hospital had an incidentally found murmur. The symptoms found in this study were not similar to those described in adults. The most commonly found symptoms were shortness of breath and fatigue, in contrast to those of chest pain and palpitations described in adults. Comparing males to females in this study, significantly lower weight (p = 0.005) and body mass index (p = 0.003) were found in girls, and a significantly lower pulse rate (p = 0.002) in boys. Left-sided cardiac enlargement was diagnosed in 11 patients on chest X-ray and in six patients on electrocardiogram. One patient had Marfan syndrome and four others had a Marfanoid appearance. In conclusion, most children with mitral valve prolapse are asymptomatic. Mitral valve prolapse is not an uncommon finding in children younger than 13 years of age. Patients with mitral valve regurgitation were advised to take infective endocarditis prophylaxis prior to invasive procedures.
