Forty-six patients with obsessive-compulsive disorder undergoing a double-blind controlled study of clomipramine and placebo were interviewed to assess changes in sexual function. Of 33 patients with previously normal orgasm, nearly all of the 24 on clomipramine developed total or partial anorgasmia; none of the 9 on placebo did so. Anorgasmia persisted with minimal tolerance over the five months that clomipramine was taken. Men and women were equally affected. Sexual side-effects are easily missed without a structured interview, and can detract from the value of drug treatment.

Nine patients have been treated by subcaudate stereotactic tractotomy for bipolar affective disorder resistant to drug treatments. In the majority, after the operation there was a reduction in frequency and severity of depressive and manic episodes. There was a trend for the operation to have more effect on the manic than on the depressive phases. Drugs which had been inert previously sometimes became therapeutically useful after surgery.

Recent literature reports suggest that the presence of Down's syndrome precludes the development of mania. A case of bipolar affective illness in a man with Down's syndrome is presented.

During 100 routine psychiatric hospital electroconvulsive treatments the medical staff administering treatment experienced little difficulty in deciding that a fit had occurred. The judgement was based on simple clinical observation of a succession of clonic bodily movements, and high inter-rater agreement was found for the measurement of fit duration. The cuff technique was also used, but it tended to underestimate fit duration and is not recommended for routine ECT practice.

The case of a young woman presenting with three distinct episodes of pseudocyesis occurring concurrently with annual hypomanic illness is described, and the association between pseudocyesis and affective disorder discussed, with regard both to possible underlying psychopathology and to previously proposed psychoneuroendocrine mechanisms.

It has been suggested that viral infections, more prevalent in the winter months, might increase pregnancy and birth complications, which might in turn be responsible for the excess of winter-born patients with schizophrenia. In this study it was found that the rate of schizophrenia among high risk winter-urban births who had suffered a perinatal complication was significantly greater than that for those who had not thus supporting the hypothesis.
