Relationship of pregnancy to coronary artherosclerosis

Abstract The relationship between pregnancy and coronary atherosclerotic blockage in Caucasian women was studied in a necropsy population. The records of accident victims and patients who died with cancer of nine primary sites were used for this purpose. Adjustments were made for age, sex, race, year of death, hypertension, and other factors known to be associated with coronary atherosclerosis. Reproductive rates, based on a value of 1.5 for twins, 1.0 for a single term birth, 0.5 for a stillbirth, and 0.25 for an abortion, were calculated for each patient. No association, either positive or negative, was found between coronary atherosclerotic blockage and the reproductive rate (pregnancy).

Poisonous Snakebites Causing No Venenation

Poisonous snakebites which do not result in venom poisoning, or venenation, occur more often than is realized. These non-venomous bites should be treated conservatively. The wound should be cleaned with germicidal soap and water, tetanus prophylaxis accomplished, and a broad-spectrum antibiotic given if necessary. Antivenin is not required, and its administration introduces the unnecessary risk of serum sickness. If venenation does occur, prompt and complete treatment is of course required.

Snakebite A Pediatric Problem

Poisonous Snakebite! An event which evokes terror and fear in the victim and his parents. It presents the physician with an emergency which requires knowledge and skill in management. The purposes of this report are: ( 1) to define the snakebite problem, (2) to describe how to identify poisonous snakes, (3) to discuss the diagnosis of snake venenation, and (4) to provide a guideline for treatment.Poisonous Snakebite!

Place in environmental epidemiology. A rectangular coordinate method.

T HE METHODOLOGY of epidemiologic investigation of acute communicable disease is beinig applied increasingly to the study of environmental health and chronic diseases. The efficacy oif this method in describing and clarifyingi the host-agent-environment interactions in the herd ecology of the human being and otlher species is no longer questioned. There is, however, one basic difference in methodology as applied to communicable disease in comparison to environmental health in the availability of data on time, place, and person. In the study of communiicable disease the factor of place, as defined by the occurrence of an epidemic, gives the initial orientation, and the remaining investigation determines the specific time and population involved. Suich a well-defined geographic locus is not generally available in environmental epidemiology except in those rare instances involving tlhe simultaneous and acute intoxication of large numbers within a population, as in the pollution of the air over Donora, Pa., fish-kills, or the epidemic of abnormal infants due to thalidomide. The many possible environmental health effects are chronic, of low intensity, and often widely scattered. Thus, identification of a sufficient number of individuals who demonstrate a mininmal effect may involve a number of species located in scattered geographic areas over a protracted period oif time. This identification, nevertheless, requires an exactitude in deteirmining place whijch must be at least equal to that of time and person.
