A preventive intervention for enhancing resilience among highly stressed urban children

Describes the development and evaluation of a pilot 12-session, school-based preventive intervention designed to enhance resilience among inner-city children who have experienced major life stress. Thirty-six 4th–6th grade children participated in the intervention in groups of 5–8 co-led by school personnel. The curriculum focussed on understanding feelings in oneself and others, perspective-taking, social problem-solving, dealing with solvable and unsolvable problems, and building self-efficacy and esteem. Pre-post evaluation showed significant improvement among participants on teacher-rated indices of learning problems and task orientation and on child ratings of perceived self-efficacy, realistic control attributions and anxiety. Program limitations and factors that restrict generalization are considered and new directions for program development and research are proposed.     

Effect of pindolol on the prolactin response tod-denfluramine

We studied the effect of the 5-HT_1A receptor antagonist, pindolol, on the prolactin (PRL) response to the 5-HT releasing agent,d-fenfluramine (d-FEN), in ten healthy male volunteers. Pindolol pretreatment lowered baseline PRL levels but, when this effect was taken into account, did not significantly attenuate the PRL response tod-FEN. Within the limitations that attend the use of pindolol as a 5-HT_1A receptor antagonist, the data suggest that although 5-HT_1A receptors may play a role in the tonic release of PRL, they are not involved in the release of PRL produced byd-FEN. We propose that the PRL response tod-FEN may involve selective activation of postsynaptic 5-HT₂ receptors.     

Lithium and 5-HT1A receptor sensitivity: a neuroendocrine study in healthy volunteers

The effect of lithium administration (800 mg daily for 7 days) on the neuroendocrine and temperature responses to the 5-HT_1A receptor agonist, gepirone, was studied in eight healthy male volunteers. Gepirone (20 mg orally) significantly increased plasma levels of prolactin, growth hormone, corticotropin and cortisol, and lowered oral temperature. None of these responses was significantly altered by lithium treatment. The results suggest that the ability of short-term lithium treatment to increase 5-HT-mediated neuroendocrine responses in humans is unlikely to be related to changes in the sensitivity of pre- or post-synaptic 5-HT_1A receptors.     

Low tolerability of carbamazepine in psychiatric patients may restrict its clinical usefulness

There are reports of prophylactic efficacy of carbamazepine (CBZ) in manic depres sives when compared with placebo and chlorpromazine. Following a successful open pilot study by one of the authors, an attempt was made to compare carbamazepine and lithium carbonate in a double-blind, crossover trial, each patient being assigned to take each drug for 9 months in random order. However, of the first 14 patients to take carbamazepine four were withdrawn because of drug rashes and another two because of other adverse effects. The trial was discontinued, and a casenotes survey of 50 consecutive psychiatric patients who had been prescribed carbamazepine for mood disorders was then carried out, to establish the tolerability of the drug in clinical practice. Of these, 22 per cent had suffered dizziness, nausea or unsteadiness despite slow introduction of doses. Drug rashes occurred in 16 per cent of patients within the two weeks of starting treatment. A further 14 per cent had other unwanted effects. In total, 36 per cent of the patients had the drug stopped because of adverse effects. With regard to efficacy, in those taking the drug for more than 4 weeks, clinicians reported a definite or probable advantageous effect in 62 per cent of the sample, definite or probable lack of effect in 19 per cent and no opinion in 19 per cent. This low tolerability is not in accordance with previous reports of 2-6 per cent incidence of drug rashes and 10 per cent overall intolerance in neurological patients. We conclude that tolerability is a major drawback to the use of carbamazepine in some groups of psychiatric patients, although all the side- effects were reversible. However, clinical impressions suggested that in a number of patients no other therapeutic strategy was as effective in preventing mood swings.     

Physical localisation of the breakpoints of a constitutional translocation t(5;6)(q21;q21) in a child with bilateral Wilms'' tumour.

A 6 month old boy presented with bilateral Wilms' tumour. Cytogenetic analysis of the lymphocytes from the patient showed a de novo balanced translocation t(5;6)(q21;q21), which was also present in the tumour material as the sole cytogenetic abnormality. To facilitate the identification of the translocation breakpoints, we have established a lymphoblastoid cell line (MA214L) from the patient which maintains the translocation in culture. We have used Genethon microsatellite markers as sequence tagged sites (STSs) to isolate yeast artificial chromosome (YAC) clones to 5q and 6q from human genomic libraries. Using fluorescence in situ hybridisation (FISH) on metaphase preparations of MA214L, we have physically defined the translocation breakpoints between YAC clones on each chromosome arm. The genetic distance separating the flanking YACs on 6q21 is 3 cM, while that on 5q21 is 4 cM. To date this is the first report of these chromosomal regions being implicated in Wilms' tumourigenesis.     

Late Niemann-Pick disease with neurovisceral storage: a classification problem.

A 51 year old man presented in 1969 with slowly progressive cerebellar ataxia of unknown origin. He was admitted to hospital aged 68 after a fall, and a ruptured spleen was removed at laparotomy. Histological analysis of the spleen suggested Niemann-Pick disease, which was subsequently confirmed. He deteriorated and died of bronchopneumonia shortly afterwards: subdural haemorrhage with storage material in neurones was found at necropsy. This late onset case of Niemann-Pick disease with neurovisceral storage is unusual and may represent a variant.
