Evidence of higher ethynylestradiol blood levels in human hypertensive oral contraceptive users.

These studies were designed to investigate the differences in blood plasma levels of ethynylestradiol (EE2) in women who developed hypertension while taking combined estrogen and progesterone oral contraceptives (OCs) and in normotensive OC users. Blood samples were collected in heparinized tubes 10 hours after OC ingestion, the plasma was separated, and EE2 was measured by radioimmunoassay. The results showed significantly higher plasma levels of EE2 in the hypertensive OC users as compared with the levels in normotensive OC users (P less than 0.01). In another study, blood samples from hypertensive and normotensive OC users were obtained for 3 consecutive days at fixed intervals following OC ingestion, and plasma levels of EE2 were measured. The results showed consistently higher EE2 blood levels during this 3-day period in the hypertensive subjects (P less than 0.01). It is postulated that the higher blood levels of EE2 in hypertensive OC users result from either decreased metabolism or excretion of synthetic estrogens.

FP/MIS: a management information system for a community family planning clinic.

The management information system (FP/MIS) used by the Howard University Center for Family Planning Services, which operates community family planning clinics in Washington, D.C. is described. The system was developed to satisfy program objectives in patient management, program planning and evaluation, resource management, federal reporting systems and clinical, epidemiological and health services research. The data collection forms used in the system and the output from the four data display groups--patient profile, resource management, quality of care and epidemiology-are described along with examples of their use.

Physical complaints of patients with sickle cell trait.

Prospective and retrospective experience with physical complaints of 112 oral contraceptive and 67 intrauterine device Black family planning patients with sickle cell trait was evaluated by comparing their cumulative complaint rates with a randomly selected control group of non-sickle cell trait family planning patients having the same method, age and parity distribution as the sickle cell trait patients. Physical complaints considered are: dysmenorrhea, mental depression, vaginal discharge, fatigue, headaches, and nausea-vomiting. No evidence of a significant difference at level .05 is found between cumulative complaint rates of sickle cell trait and control patients for either oral or intrauterine device users for any of the complaint types. Further clinical research may be desirable in this area for dysmenorrhea and mental depression.
