The mentally handicapped person with epilepsy: a comparative study investigating psychosocial functioning.

A sample of institutionalized, mentally handicapped adults who suffered from epilepsy was compared with a matched control group without epilepsy in order to investigate profiles of adaptive skills and of behavioural disturbance. Results suggested that mentally handicapped people with epilepsy have consistently poorer life skills than their peers with no epilepsy but behavioural disturbance was not significantly elevated, except for a small sub-group whose epilepsy was resistant to pharmacological control. These results are discussed with reference to past research and management implications are considered.

Observed activities of serum creatine kinase: total and B subunit activity and other enzymes in young persons abusing solvents.

Serum enzymes (aspartate transaminase, alanine transaminase, alkaline phosphatase (ALP), gamma-glutamyltransferase, and creatine kinase (CK] were measured in 296 young persons who admitted to recent inhalation of solvents, usually toluene based glues. In general, results fell within expected adult reference ranges except for ALP and CK. About 60% of subjects had CK activities above the upper reference limit and these activities were investigated in terms of their isoenzyme composition. CK B subunit activity was measured in 90 subjects with raised total CK activities. In five instances the CK B subunit activity was judged abnormal and in two subjects the presence of CK BB was confirmed. These two subjects were thought to have a circulating macro CK, type 1. It is concluded that the increased total CK activity found in this group of solvent abusers was due to physical activity, but a contribution from specific muscle toxicity by solvents cannot be excluded.

Reduced steady-state plasma concentrations of chlorpromazine and indomethacin in patients receiving cimetidine.

Chronic administration of cimetidine was found to produce a fall in steady-state plasma concentrations of chlorpromazine and of indomethacin in patients. In each case there was some evidence of inhibition of metabolism, suggesting that the mechanism must therefore be decreased absorption sufficient to over-ride the metabolic change. This was confirmed by measurement of excretion of metabolites in the indomethacin study. The fall in indomethacin plasma concentrations was not associated with a change in the clinical effectiveness of the anti-inflammatory therapy.
