Behavioral recovery in albino rats with glutamate-damaged retinas.

Adult, male, albino rats were trained to discriminate between two patterned stimuli in a T-maze. Performance on this task was assessed following intravitreal injection of 1 mumol glutamate. Discrimination performance declined to nearly random levels by 1 day postinjection and remained significantly depressed for 2 weeks. However, by 2 months after injection, there was evidence of behavioral recovery to preinjection levels despite significant loss of inner retinal neurons. Task-related experience immediately following or 2 months after injection proved both necessary and facilitative for recovery.

Controlled study of child health supervision: behavioral results.

Extensive child health supervision, with emphasis on counseling and anticipatory guidance, was provided for the first three years of life to an experimental series of 47 normal first-born black infants from low-income families living in the environs of Children's Hospital in Washington, D.C. The mothers were unmarried schoolgirls in normal physical and mental health. A control series consisted of 48 similar mother-child dyads from the same area. Data were collected, in part by an outside evaluator, at yearly intervals on both experimental and control series in a form suitable for coding on computer cards. Comparison of differences in behavioral results between the two series showed statistically significant findings in favor of the experimental children, as well as numerous favorable trends during the first six years of life. Positive effects became evident in diet and eating, habits, in some developmental problems of growing up (such as toilet training), and in certain abstract qualities including self-confidence. Significant differences were also noted between the experimental and control mothers for various child rearing practices and personality characteristics. No significant difference or trend favored the control series. We believe that a causal relationship existed between the intervention and at least some of the significant findings.

Am empirical study of selected cost measures of clinical engineering service effectiveness.

The growing demand for more and better healthcare service greatly expands the role of medical equipment in providing health services more effectively. The purpose of introducing clinical engineering programs in hospitals was to improve the effectiveness of healthcare institutions' utilization and management of medical technology. Over the last decade, the role of clinical engineering has grown in importance as a component of hospitals and the healthcare delivery system. Hospital administrators currently put a strong emphasis on cost effectiveness of clinical engineering services, to reduce the cost of acquisition and maintenance of equipment. Unfortunately, the lack of a commonly accepted definition of cost effectiveness has resulted in a certain amount of confusion over how the performance of clinical engineering services can or should be measured. The results presented in this paper should assist hospital administrators and clinical engineering program managers to establish a common understanding of what "cost effectiveness" means and how it can be achieved.
