Torsion dystonia: a case report.
A 35-year-old black female with typical torsion dystonia is discussed. Tremors in the right upper extremity began with a febrile illness at age eight. Difficulty in using the extremity began two years later. Overt writhing movements and torticollis began at age 17. The disorder has been progressive, but not disabling. Neurological examination revealed only extrapyramidal motor system dysfunction. Serum dopamine Beta hydroxylase levels were normal, and an evaluation for Wilson's disease was negative. A sibling has minor writing difficulties.

Changes of blood pressure, renin, and angiotensin after bilateral nephrectomy in patients with chronic renal failure.
Circulating levels of renin, angiotensin I, and angiotensin II were increased in six patients with chronic renal failure and hypertension uncontrolled by dialysis and hypotensive drugs. Lower and often normal levels were found in 10 patients whose blood pressure was controlled by dialysis treatment. For a variety of reasons all patients were subjected to bilateral nephrectomy. The logarithm of the decrease in plasma concentrations of renin and angiotensin II was significantly related to the fall of blood pressure after operation. Plasma renin concentration correlated significantly with blood angiotensin I concentration and with plasma angiotensin II in samples taken before and after nephrectomy. Renin, angiotensin I, and angiotensin II were measurable in samples of blood taken 48 hours or more after the operation.
Pediatric use of emergency departments.
This cross-sectional survey examined the use of emergency services by children, from birth to 16 years of age, in two urban teaching hospitals. A retrospective chart survey design was used to obtain data on the prevalence of types of patient problems; the pattern of use, including time of day and day of week; and decisions regarding patient disposition. A random sample of 10% of the average monthly pediatric emergency visits was obtained for a 12-month period and relevant data were extracted by trained research assistants. Variation in the presenting health care problems by age group, season of the year, and by time of day and day of the week was found. Approximately 50% of visits involved such primary health care problems as soft tissue injuries, and respiratory and digestive tract infections. Possible reasons for this use of emergency departments for primary care needs are discussed and strategies are suggested for the provision of a better "fit" between consumer demand and health care services.
The impact of personal and situational variables on career patterns among nurses from three types of educational programs.
Relationships between educational preparation and employment choices were investigated in a study of the career paths of nursing graduates from three types of educational programs: a community college diploma program, a generic baccalaureate program, and a postdiploma baccalaureate program. Selected personal and work-related correlates of career paths for the three groups also were explored. All available graduates for the years 1984 to 1990 from the three programs (n = 1,544) were sent a self-administered questionnaire. Data were collected concerning demographic variables, employment details, ongoing professional development, and level of satisfaction with nursing. Analysis of the data demonstrated clear variations in the career paths of the three groups of graduates, supporting the belief that the type of educational program does indeed have a steering effect on the subsequent career choices of these nurses.
