Misplacement in long stay geriatric care, psychogeriatric care and Part IV accommodation.

The dependency and behavioural characteristics of 1,461 elderly people in long stay geriatric and psychogeriatric wards and Part IV accommodation were surveyed. Misplacement, defined as having dependency and behaviour characteristics normally associated with admission to another form of care, was widespread, ranging from 5-51% in the different facilities visited. It was greatest in psychogeriatric wards and least in geriatric wards. In Part IV accommodation there was a significant inverse relationship between length of stay and appropriateness of placement.

Effects of methylphenidate alone and in combination with behavior modification procedures on the behavior and academic performance of hyperactive children.

Twenty hyperactive 6- to 9-year-old children of normal intelligence were studied in a half-day laboratory classroom in a 2-week period baseline-treatment-reversal design for behavior modification. Under double-blind conditions half the children were placed on .3 mg/kg of Ritalin and half on placebo for the entire program. The classroom program consisted of a group period with immediate reinforcement possible, and an individual time period without immediate reinforcement possible. Behavior modification caused a significant decrease in nonattending, out-of-seat, inappropriate vocalizing and inappropriate peer interaction behavior in the group period. Fidgeting, a nontargeted behavior, was not significantly decreased during this period but did significantly decrease as a result of medication. No other drug effects occurred during this period. During the individual period, the results were essentially reversed. There were no significant behavior modification effects observed. Significant reductions resulted from medication in all behaviors except out-of-seat and fidgeting. Behavior modification alone significantly affected the two academic measures. No signigicant effects were seen on the Conners Abbreviated Teacher Rating Scale. No significant interactions were noted between medication and behavior modification.

Immunohistochemical detection of changes in growth hormone cells in rat pituitaries in protein deficiency.

1. An immunohistochemical method was used to study the effect of a low-protein diet on growth hormone (GH) cells in the pituitaries of developing rats. The deficient diet (80 g protein/kg) was administered during gestation and lactation, or during the time after weaning until 90 d of age, or during both periods. 2. GH-cell changes were much more striking in males than in females. 3. In males, GH-producing cells were usually reduced in size and number in all treatments. The effect was most intense when protein deprivation occurred throughout gestation and sucking, and continued until 90 d of age, but it was also evident in animals given the low-protein diet only after weaning. Recuperation appeared to be almost complete when offspring of deprived dams were fed on a normal diet after weaning. 4. It is concluded that a low-protein diet reduces the amount of GH in the rat pituitary in a way similar to that with a protein-free diet.
