A young female presented with haemolytic anaemia due to dapsone overdosage. She developed peripheral neuropathy and marked visual impairment with a cherry red spot on the macula, possibly due to toxic retinal vascular damage; both these resolved in due course. Cherry red spot due to dapsone poisoning has not been reported previously.
A double-blind clinical trial was undertaken to evaluate clinical efficacy and safety of fluoxetine in comparison with the standard tricyclic antidepressant, imipramine, in the treatment of depressive illness. The opportunity was taken to compare the relationship of some standard measures of depressive illness, two observer based--Hamilton Depression Rating Scale and the Montgomery-Asberg Depression Rating Scale (Montgomery and Asberg, 1979)--and a self-rating scale--Levine Pilowsky Depression questionnaire (Pilowsky et al., 1969).
This clinical trial of a new antidepressant, fluoxetine, shows it to be as effective as a standard tricyclic drug, imipramine. It is effective as a single daily dose and is free of any significant side-effects. It is less sedative and appears to cause fewer problems of weight increase. The three scales used to assess efficacy showed a very positive correlation.

Suicide mortality in a northern town of Sri Lanka for the year 1982 is examined. The rate was 53.5 per 100,000 general population and shows an increasing trend amongst the 15-34 age group. The commonest method was self-poisoning by agrochemicals and insecticides of organophosphorus type. Psychiatric diagnosis, social, economic and political factors are presented. Easy availability of dangerous agrochemicals and rapid social and political changes appear to be of equal importance in producing a high rate of suicide.
