    Notes: Background  Topical corticosteroids are the usual treatment for atopic dermatitis (AD) in children but can have side-effects.Objectives  This study compared the efficacy and safety of 0·03% tacrolimus ointment applied once or twice daily over a 3-week period with the twice daily application of 1% hydrocortisone acetate (HA) ointment in children with moderate to severe AD.Patients and methods  Patients applied ointment daily to all affected body surface areas. The primary study endpoint was the percentage change in the modified Eczema Area and Severity Index (mEASI) between baseline and treatment end.Results  Six hundred and twenty-four patients, aged 2–15 years, applied 0·03% tacrolimus ointment once daily (n = 207), twice daily (n = 210) or 1% HA twice daily (n = 207). By the end of treatment, application of 0·03% tacrolimus ointment both once or twice daily resulted in significantly greater median percentage decreases in mEASI (66·7% and 76·7%, respectively) compared with 1% HA (47·6%; P 〈 0·001). Furthermore, the median percentage decrease in mEASI was significantly greater for patients applying 0·03% tacrolimus twice daily compared with once daily (P = 0·007). Patients with severe AD benefited especially from twice daily application of 0·03% tacrolimus ointment compared with once daily application (P = 0·001). Transient mild to moderate skin burning occurred significantly more often in the 0·03% tacrolimus groups (P = 0·028) but resolved in most cases within 3–4 days. Laboratory parameters showed no clinically relevant changes.Conclusions  0·03% tacrolimus ointment applied once or twice daily is significantly more efficacious than 1% HA in treating moderate–severe AD in children. Twice daily application of 0·03% tacrolimus ointment results in the greatest improvement in mEASI, and is especially effective in patients with severe baseline disease.

    Notes: Serum concentrations of pregnenolone sulphate, dehydroepiandrosterone sulphate and 5-androstene-3β, 17β-diol sulphate were measured by radioimmunoassays in twelve patients with various types of ichthyosis. In X-linked ichthyosis (n = 5), ichthyosis vulgaris (n = 5) and lamellar ichthyosis (n = 1), steroid sulphates were not significantly higher than in the control subjects. In one baby with ichthyosiform erythroderma and associated deafness serum 5 -androstene-3β, 17β-diol sulphate concentration was about 60 fold higher (31 μg/ml) than the mean of the control children. The other steroid sulphate levels were normal in this baby.These results indicate that it is not possible to demonstrate the steroid sulphatase deficiency in X-linked ichthyosis by determining blood steroid sulphates. The cause of the high 5-androstene-3β, 17β-diol sulphate concentration in the baby with ichthyosiform erythroderma needs further evaluation.

    Notes: Collagen synthesis and the ratios of collagen types I and III were assayed from the skin lesions of five subjects with tuberous sclerosis. Collagen synthesis, measured by the activities of prolyl hydroxylase and galactosylhydroxylysyl glucosyltransferase, was clearly increased in three angiofibromas of these patients and in one soft tumour of the face, but it was unchanged in shagreen patches. The total collagen content was decreased in angiofibromas, indicating either increased turnover of collagen or an increased amount of cellular or other macromolecular elements in these lesions.The proportions of types I and III collagens, estimated by cyanogenbromide digestion and SDS-gel electrophoresis, were 80–90% and 10–20%, respectively, in all samples except two angiofibromas, in which the relative amount of type III collagen was increased. This may indicate that angiofibromas of tuberous sclerosis are heterogenous with respect to the collagen types they contain, and that there may be disturbed cell growth or collagen synthesis, with individual variation from case to case.
