Case reports of anorexia nervosa in subjects of Asian (Indian subcontinental) extraction have been rare. Three Asian adolescents with anorexia nervosa are described, one of whom is male. The impact of the Muslim festival of Ramadan is described in the two Muslim cases. There is a need for better understanding of attitudes towards body shape and food within the subculture.

A case of an unusual pica in a patient with anorexia nervosa is described. The patient was also found to have iron-deficiency anaemia. The relationship of mineral deficiency to pica and anorexia nervosa is discussed.

In the search for neurobiological factors in the aetiology of autism, interest has focused on the temporal lobes. We present a case of Asperger's syndrome in an otherwise healthy adult with direct evidence of left temporal lobe damage on computerised tomography.

A patient experienced an organic affective psychosis on three separate occasions after taking recommended doses of non-prescription cold/sinus preparations. The possible underlying pharmacological mechanisms of this clinical reaction lend support to the cholinergic-adrenergic balance hypothesis of affective disorders. Recognition of this acute drug-induced state can lead to appropriate short-term pharmacotherapy and can prevent misdiagnosis of a major affective disorder or schizophrenia.

A patient with a paranoid schizophrenic illness showed features of two rare syndromes, Capgras and de Clérambault's.

Dhat syndrome is a culture-bound sex neurosis of the Indian subcontinent. Fifty-two patients with a presenting complaint of passage of ‘Dhat’ in urine were studied. Diagnosis of neurotic depression, anxiety neurosis, hypochondriacal neurosis, and psychogenic impotence were made in 21, 19, 3, and 1 cases respectively. Seven patients received the diagnosis of pure Dhat syndrome, and one of gonorrhoea.

A case is described of NMS during treatment with sulpiride. The subsequent psychosis resolved during treatment with carbamazepine. It is proposed that this patient may have suffered from a supersensitivity psychosis, and that resolution of her post-NMS psychosis could have been spontaneous.

Recognising confusion as an antecedent to NMS may help abort the full-blown syndrome. Two such cases are reported, along with a third.
