Brief Reports

Mental Disorders among Yugoslav Medical Students The mental health of 523 medical students was examined one month after enrolment and two years later. The point prevalence rates of all mental disorders were 16.1 % and 17.5% respectively. The incidence rate was 5.3% per year, with neuroses being the most frequent diagnoses (3.5%).

Those participants who failed again in the spring term were asked by post when and where they could be approached and re-examined.

Even

if it is

possible (Smith et al, 1963), any comparison is usually hampered by the differences that exist among the student populations examined or instruments used. The overall frequency of mental disorders in our study was somewhat higher at -the second examina tion, but the difference was not significant (@=0.27; d.f.=1).

The absence of psychotic disorders on enrolment was a consequence of a previously applied selection procedure which excluded candidates with serious psychiatric impairment. Two students who developed

by Smith et al (1963).

Mephentermine

Dependence with Psychosis A Case Report

Dependence on mephentermine, a widely used sympathomimetic pressor agent, is so far unreported, although misuse of inhalers is recognised. A case of mephentermine dependence associated with chronic psychosis is reported here. Psychosis initially surfaced with chronic dexamphetamine abuse, but was sustained for 3 years by mephentermine. After a period of remission lasting for 4 years, the patient again developed psychosis on restarting abuse of mephentermine, which lasted for 5 years. Mephentermine, close structural

a sympathomimetic amine with a similarity to methamphetamine, is

used mainly as a pressor agent in various hypotensive states (Weiner, 1985). It has both alpha and beta adrenergic activity, acts mainly indirectly by releasing noradrenaline from adrenergic nerve endings, and has a slight stimulating effect on CNS (Reynolds, 1982). Although its potential for amphetamine type dependence is recognised (Reynolds, 1982), there are no reported cases of mephentermine dependence.

There are only two earlier reports of mephentermine misuse without evidence of dependence (Greenberg & Lustig, 1966; Angrist et a!, 1970). Both reported short-lasting acute paranoid psychosis, similar to amphetamine psychosis, following ingestion of the contents of mephentermine inhalers. We report a case of mephentermine dependence associated with

chronic psychosis. This is probably the first reported case of mephentermine

dependence.

Case report Dr P, a 37-year-old male medical practitioner,

was admitted

in October 1985 with a history of injecting Mephentine@ (30mg intramuscularly, 4—5 times daily) for about 5 years. According to the patient he injected Mephentine “¿to get relief from feelings of boredom, nervousness, desperation and worries about the future―.Within 20—30minutes of injecting Mephentine he experienced relief from these feelings and also felt relaxed and euphoric for a few hours. Hence, he took injections regularly at least four times a day, and up to six times on some days. In spite of being a doctor, when desperate due to lack of privacy he took injections surreptitiously, without any antiseptic precautions, in the toilet, and sometimes even through clothing.
