Scanning electron microscopy of scales from pityriasis amiantacea.

The scanning electron microscope has been used to examine scales taken from the scalp of 3 patients with pityriasis amiantacea alone, 3 psoriatic patients with pityriasis amiantacea and one patient with both atopic dermatitis and pityriasis amiantacea. Samples from 2 patients were additionally studied by different fixation techniques and in the frozen hydrated state, but no cementing of the scales could be observed. There was no evidence of an infective agent.

Pyoderma faciale in a patient with Crohn's disease.

We wish to report the progress of a patient with pyoderma faciale and Crohn's disease. The patient is interesting in that on two occasions the relapse in her skin condition coincided with the introduction of non-steroidal anti-inflammatory drugs. Therapy with isotretinoin was effective and well tolerated.

Cutaneous granulomata complicating desensitization.

D-VAC Pollens (Bencard), a standard depot pollen vaccine, was withdrawn in the mid-1970s. We report a case in which subcutaneous granulomata developed 12 years after desensitizing injections by this product.

Epidemiology of molluscum contagiosum using genetic analysis of the viral DNA.

The molecular epidemiology of molluscum contagiosum virus (MCV) infections was investigated by restriction endonuclease analysis of the genomes of 222 separate isolates collected from 147 patients living in Germany (33 patients), Hong Kong (6 patients), and Scotland (108 patients). MCV type 1 (MCV-1) caused 96.6% of the infections, and MCV type 2 (MCV-2) caused 3.4%. However, isolates from four of the 142 MCV-1-infected patients and two of the five MCV-2-infected patients showed minor differences in their DNA restriction patterns because of the loss of a single or very few recognition sites for the enzymes used. No genome variations were detected amongst isolates collected from different sites or on several occasions from individual patients or from closely related patients. Southern blot hybridization revealed a high level of relatedness between MCV-1 and 2. No differences were seen in the appearance or anatomical localization of lesions caused by either virus type. In particular, there was no preferred genital localization for MCV-2 infections.

The effect of washing on the thickness of the stratum corneum in normal and atopic individuals.

The thickness of, and number of cell layers in, the stratum corneum and the living epidermis were determined on frozen sections of washed and unwashed skin from normal and atopic individuals of both sexes. The stratum corneum of atopic patients was thinner and had fewer layers of dead cells and intercellular lipid than normal, although the living epidermis was thicker. Regular washing with soap and water had no appreciable effect on the dimensions of the living epidermis of either group but caused a reduction in the number of cell layers and the amount of sudanophilic material in the stratum corneum of both. In atopic patients little surface lipid remained, suggesting that washing with soap and water may be detrimental to the barrier function of the stratum corneum in such patients.

Incontinentia pigmenti in a boy with Klinefelter's syndrome.

A boy with the cutaneous lesions of incontinentia pigmenti is described. Chromosomal analysis revealed the 47,XXY karyotype of Klinefelter's syndrome. Since incontinentia pigmenti trait is usually lethal in males, the possibility of the second X chromosome protecting against fetal death is discussed.

Terfenadine and brompheniramine maleate in urticaria and dermographism.

The effects of brompheniramine maleate (12 mg twice daily in sustained release form) and terfenadine (60 mg twice daily) on the symptoms and well-being of 16 adults with urticaria with or without dermographism were assessed by symptom questionnaire. Following an initial 2-week period without therapy, each drug was taken for 2 weeks in a randomised double-blind cross-over study. Both drugs produced significant relief of itch and rash but only brompheniramine produced significant drowsiness. Brompheniramine maleate was more effective than terfenadine in the patients with dermographism.
