The relation between oral contraceptive use and subsequent development of hyperprolactinemia.

Serum prolactin levels were determined in 123 patients who presented with menstrual irregularities and/or infertility of more than 1 year's duration. Sixty-three patients had hyperprolactinemia with serum prolactin levels of 26 to 843 ng/ml (normal 5 to 22 ng/ml); 44.4% of this group of patients received oral contraceptive for a period of 2 months to 7 years. Sixty patients were normoprolactinemic, with serum prolactin levels of 3 to 22 ng/ml; 33.4% of this group received oral contraceptives for a period of 6 months to 7 years. The age of presentation, onset of symptoms, age at which they started on oral contraceptives, and duration of use were tabulated. The data were analyzed using chi 2 test corrected for continuity. There was no significant difference in age at the time of evaluation between oral contraceptive users and nonusers with hyperprolactinemia. The relative odds developing hyperprolactinemia were 2.64 times greater among women who has used oral contraceptives for more than 1 year and 6.25 times greater if this use started before the age of 25.

Estimating demand for emergency transportation.

Current and future demands for emergency transportation services are estimated relative to actual and potential use by the population at risk. Correct and incorrect utilization are defined by matching levels of responses (MICU, BEA, Transfer Vehicle, Nonemergency Vehicle, Transport/Private Vehicle) to the level to severity (Life-threat, Urgent, Routine, Transfer, Dry Run). From these definitions and data available from emergency facilities, demand and need are calcualted. Multiple regression models are developed for estimating future demand. Data from a rural county is then used with the models to develop the predictive equations. In both cases, five significant variables explain over 90 per cent of the variation in number of calls for emergency transportation services.

Neural properties of cultured human endocrine tumor cells of proposed neural crest origin.

Cells from human endocrine tumors of proposed neural crest origin--five pheochromocytomas, two medullary carcinomas of the thyroid, and two bronchial carcinoids--were grown in monolayer culture. Cells from all nine tumors, including epithelial forms of medullary carcinoma of the thyroid and bronchial carcinoid cells, and epithelial and neuron-like pheochromocytoma cells demonstrated all-or-nothing, short-duration action potentials.

The effect of a target date based utilization review program on length of stay.

This study was conducted to determine whether implementation of a specific formalized concurrent utilization review system which involved making a prior determination of length of stay had any more effect on average length of stay than continuance of a utilization review method not involving assignment of such a target date. The system studied was the Pre-Discharge Utilization Review (PDUR) program used for Medicaid patients in Pennsylvania. Analysis was conducted using discharge abstracts for Medicaid patients under age 65 who were discharged with one of 14 common diagnoses for certain Allegheny County hospitals in 1972 and 1973. Comparisons were made for each individual diagnosis to control for possible differences in case mix. Results indicate that there was no general reduction in length of stay which could be attributed to the PDUR program.
