Juvenile xanthogranuloma with recurrent subdural effusions.

A 2-year-old girl with extensive cutaneous xanthogranuloma and recurrent subdural effusions has been investigated. Differentiation from histiocytosis X depended upon light and electron microscopical studies of the cutaneous infiltrate and cells obtained from the cerebrospinal fluid. The recurrent subdural effusions responded well to cranial irradiation. Although juvenile xanthogranuloma is generally a benign cutaneous disorder, a spectrum of naevoid proliferative changes involving systemic organs may occur.

Razoxane (ICRF 159) in the treatment of psoriasis.

This paper describes our experience with the use of razoxane (ICRF 159), a new anti-mitotic drug, in the treatment of thirty-six patients with severe psoriasis. The drug has proven highly effective both in cutaneous and in arthropathic disease. The drug is well tolerated by patients and appears to be free of hepatotoxicity. However, it causes depression of the neutrophil leukocyte count, an effect which is entirely dose-dependent; the hazard to patients can be minimized by careful supervision of therapy.

Cockade naevus: an unusual variant of the benign cellular naevus.

A patient with benign cellular naevi with unusual target-like morphology is described. Histological and histochemical examination of the lesions showed Dopa oxidase positive cells in the epidermal portion of the tumour but only the naevus cells and keratinocytes at the periphery of the tumour stained for melanin. It is suggested that failure of melanin synthesis is the cause of the target-like appearance.

EDS IV (acrogeria): new autosomal dominant and recessive types.

Evidence is presented that type IV of the Ehlers-Danlos syndrome (EDS IV) is genetically variable. A benign autosomal dominant form and two autosomal recessive variants are described with clinical and biochemical features that are distinct from classical acrogeria.

Enzymatic basis of typical X-linked icthyosis.

Steroid sulphatase activity was determined in cultured fibroblasts from 25 individuals with X-linked ichthyosis from four countries. All those with X-linked disease had markedly reduced enzyme levels compared with controls and patients with other types of ichthyosis. X-linked ichthyosis seems to be the result of a common mutation affecting the expression of steroid-sulphatase activity.

A double-blind controlled crossover trial of an antigen-avoidance diet in atopic eczema.

20 out of 36 children (aged two to eight years) with atopic eczema completed a twelve-week, double-blind, controlled, crossover trial of an egg and cows' milk exclusion diet. During the first and third four-week periods, patients on an egg and cows' milk exclusion diet received a soya-based milk substitute (trial period) or an egg and cows' milk preparation (control period). Response was assessed in terms of eczema activity, number of areas affected, pruritus, sleeplessness, and antihistamine usage while on the two diets. During the middle period patients resumed their normal diet to minimise any carry-over effect. 14 patients responded more favourably to the antigen-avoidance diet than to the control diet, whereas only 1 responded more favourably to the control diet than the trial diet. Patients experienced more benefit during the first diet period than the second, whatever the nature of the diet. There was no correlation between a positive prick test to egg and cows' milk antigen and response to the trial diet.

Defective yeast opsonization and C2 deficiency in atopic patients.

Twenty-seven per cent of atopic patients initially presenting with infantile eczema or hay fever were defective for yeast opsonization and 18% had low levels of C2; these deficiencies were mutually exclusive, suggesting that they are primary. Both defects were associated with each of four different atopic syndromes, some of which were related to certain HLA haplotypes.

HLA in eczema and hay fever.

The presumed HLA haplotype A1:B8 was more frequent and the combination of A3 and B7 was less frequent in allergic subjects presenting with eczema, than in those presenting with hayfever. A1:B8 was most frequent (36%) in eczema complicated by asthma and/or hay fever, and least frequent (5%) in hay fever alone, considerably above and below the frequency in the general population (17%).
