Endocarditis prophylaxis for patients with mitral valve prolapse. A quantitative analysis

Antimicrobial prophylaxis of bacterial endocarditis is widely recommended for patients with mitral valve prolapse who undergo procedures that may cause bacteremia. The benefits and risks of this practice have been analyzed on the basis of published data and response to a questionnaire survey of leading authorities on bacterial endocarditis. Among 10 million patients with mitral valve prolapse undergoing a dental procedure, an estimated 47 nonfatal cases and two fatal cases of bacterial endocarditis would occur if no prophylaxis were given, five cases of bacterial endocarditis and 175 deaths due to drug reactions would occur if all patients were given prophylaxis with a penicillin, and 12 nonfatal cases and one fatal case of bacterial endocarditis would be expected if a policy of prophylaxis with erythromycin were adopted. Even using assumptions most favorable to the penicillin regimen, this analysis predicts that no prophylaxis and penicillin prophylaxis would result in a similar number of deaths. No prophylaxis or prophylaxis with erythromycin appears preferable to prophylaxis with a penicillin.

Hypernatremic dehydration in nursing home patients: an indicator of neglect

In order to determine the antecedents of hypernatremic dehydration the authors reviewed the records of 56 patients with this condition at two public hospitals, one of which includes a large chronic care facility. Twenty-nine patients developed hypernatremic dehydration while at nursing homes. All cases came from proprietary nursing homes, although proprietaries account for only 88 per cent of nursing home beds in the community studied (P less than 0.05). There was a cluster of patients from two nursing homes. Sixteen patients admitted from home all showed evidence of inadequate care prior to admission. Eleven patients became hypernatremic while in acute care hospitals. No patient in the public chronic care facility developed hypernatremic dehydration during the period studied. The average serum sodium concentration of patients transferred from nursing homes was significantly higher than that of patients who developed hypernatremic dehydration at home or in acute care hospitals. It is concluded that hypernatremic dehydration in an institutionalized patient may be an indicator of inadequate care, which should prompt further investigation of the living conditions of the patient.

Public money, private control: a case study of hospital financing in Oakland and Berkeley, California

Government support of public and private hospitals in Oakland and Berkeley, California was investigated. The private hospitals received government subsidies amounting to at least 60 per cent of their total revenues. The dollar amount of the subsidies to private hospitals was four and one-half times greater than government expenditures on the public hospital. In Oakland and Berkeley, as in many cities, public medical services have been reduced while both government health expenditures and private hospital revenues have increased sharply. The private hospitals, although all nominally non-profit, exhibit revenue maximizing behavior which results in socially unjust and medically irrational resource allocation. Funds might be found for public hospitals and clinics, and resources allocated more justly and rationally, if government expenditures in the private sector were brought under greater public scrutiny and control.

Sex differences in alcohol-related disease at a county hospital

A retrospective study of alcohol-related disease at a county hospital is reported. Fifteen percent of patients had an alcohol-related primary diagnosis, and 38% were found to have at least one alcohol-related diagnosis. Women made up 19% of the patients with all alcohol-related diagnoses, but they constituted 35% of those with cirrhosis of the liver and 50% of the patients with hepatic encephalopathy and hepatic failure. Only 6% of the patients diagnosed as having alcohol withdrawal syndrome were women.

Hypernatremia in the elderly: relation to infection and mortality

The records of 23 elderly patients admitted to a county hospital with dehydration and hypernatremia were reviewed. One of these patients had the highest serum sodium level (202 mEq/L) reported in an adult. The overall mortality of 48 percent was not related to the degree of hypernatremia. However, two-thirds of the 17 patients with acute bacteria infections died, whereas all 5 noninfected patients survived. Infection was not always apparent at the time of admission to the hospital. It is proposed that early and appropriate antibiotic therapy may reduce the high mortality associated with hypernatremia in the elderly.

Atrial myxoma infected with Candida: first survival

We report the first case of an atrial myxoma infected with the fungus, Candida tropicalis. We believe that this is the only patient with an atrial myxoma, infected with any species of Candida, who has demonstrated long-term survival. A review of the world's literature of infected myxomas is presented.
