Disposition of presumed coronary patients from an emergency room. A follow-up study.

All patients with presumed coronary problems seen at the Chaim Sheba Medical Center during a one-year period were followed up. The fate of those who were not hospitalized and the factors contributing to the two types of erroneous decisions, ie, refusing hospitalization to those needing it and unnecessary hospitalization of others, were evaluated. Approximately 50% of the patients were not admitted. Myocardial infarctions were later diagnosed in 6% of these patients. Another 8% were eventually categorized as other cardiac emergencies. Ten percent of all patients subsequently diagnosed as having myocardial infarctions were not admitted. On the other hand, 56% of the patients whose cases were later not considered to have been emergencies were hospitalized unnecessarily. Previous hospitalization for cardiac disease played a major role in making an error of both types. Other factors influencing the physician's decision regarding the patients' disposition included their age, sex, ethnic origin, and the findings from the emergency room electrocardiogram.

Low-fiber intake as an etiologic factor in cancer of the colon.

A case-control dietary study of 198 patients with cancer of the colon and two matched control groups demonstrated a significantly lower fiber consumption frequency among the cancer patients. This difference was not confined to a few items. Of the 73 items on the fiber list, 61 were eaten less often by the cancer patient than by a neighborhood control, and 57 were consumed less frequently than by a surgical control. These findings support the hypothesis that low-residue foods play an etiologic role in colon carcinogenesis. A mechanism related to the possible potential carcinogenic properties of degraded biliary compounds may be implicated.

An epidemiologic study of renal failure. I. The need for maintenance hemodialysis.

A nationwide morbidity study of end-stage kidney disease in Israel revealed a mean annual incidence rate, in the two-year period 1965-1966, of 70 cases per million per year requiring maintenance hemodialysis in the age 15-59 Jewish population. Chronic glomerulonephritis (38%) chronic pyelonephritis (24.9%) and polycystic disease (8.1%) represented the three most common diagnostic entities. It is suggested that the load of new cases on available dialysis units will not increase indefinitely but that an equilibrium will be established between the intake of new candidates and the outflow due to deaths and transplantation.

An epidemiologic study of renal failure. II. Acute renal failure.

A total community study of acute renal failure (ARF) was carried out in Israel. The mean annual incidence was 4.8/100,000, the risk being 50% higher in males than in females. It was found that ARF is due primarily to a multiplicity of factors and rarely to a single cause; the high mortality associated with ARF is related to the patient's basic underlying condition. The epidemiology of ARF results from a compilation of the various conditions leading to it, and would, therefore, vary according to the differential distributions of these conditions in the population.

Dietary factors and cancer in Israel.

The risk of developing cancer is relatively higher in the European-born Israeli population than in those originating from the Middle Eastern or North African countries. The majority of cancer sites with a higher risk in the European groups involve the gastrointestinal and reproductive systems. Certain leads suggest that at least some of these differences may be attributed to diet. Data based on case-control studies are provided; they indicate a high consomption of starches among gastric cancer patients and a lower fiber consumption in patients with cancer of the colon. The latter observations may be extended to cancer of the breast, ovary, and corpus uteri, assuming an interplay between the concentration of bile degradation products and hormone metabolism. Although a low fiber consumption seems a more likely mechanism, a higher fat consumption is also compatible with this model. However, due to the complexity of human nutrition, it seems unwarranted to incriminate any single dietary factor in carcinogenesis. A better understanding of the metabolic pathways, coupled with consistent observations from distinct populations, should be looked for.

Epidemiology in health policy.

As a problem-oriented discipline that deals quantitatively with sickness and health, the needs of populations, and the effectiveness of health services, epidemiology can make a considerable contribution to decision-making on health policy. Examples are presented to illustrate the use of the epidemiologic approach at national, regional and local community levels, and its potential contribution to decisions concerning the allocation of resources and the determination of program priorities.
