Practical use of a disability index in the routine management of acne.

We describe a brief questionnaire designed to assess the disability caused by acne. The questionnaire adds a patient-orientated dimension to medical records, high-lights patients with unusually high levels of disability, and increases the relevant information on which we base therapeutic decisions.

Longitudinal study of cortical bone loss in patients with inflammatory bowel disease.

Bone mineral density of the radius was measured by single-photon absorptiometry in 50 patients with inflammatory bowel disease. Thirty-three had Crohn's disease and 17 ulcerative colitis; 25 were women. The mean age was 45 years (range, 18-70 years). Measurements were repeated in 39 of them after a mean follow-up period of 7.9 years (range, 7.1-8.2 years). In female patients the mean (95% confidence interval) annual change in radial bone mineral density was -0.74% (-1.34% to -0.14%) (P = 0.022), the greatest bone loss occurring in postmenopausal women (mean, -1.16% (-2.01% to -0.30%)). In male patients the mean annual rate of bone loss was -0.07% (-0.41% to 0.28%) (P = NS). Patients with abnormally low values at the first measurement remained osteopenic at the second measurement, whilst some others with normal values initially showed increased rates of bone loss and had a subnormal bone mineral density after the follow-up period. These results show increased rates of cortical bone loss in some patients with inflammatory bowel disease and emphasize the need to monitor bone mass in these patients so that prophylactic measures can be instituted.

Double-blind, controlled, crossover study of cyclosporin in adults with severe refractory atopic dermatitis.

A few patients remain severely affected by atopic dermatitis into adult life despite treatment with systemic steroids, azathioprine, and photochemotherapy. 33 patients took part in a double-blind, placebo-controlled, crossover study to assess the efficacy and safety of cyclosporin (5 mg/kg per day) in adults with severe refractory atopic dermatitis. Treatments were given for eight weeks each with one group (n = 16) receiving placebo followed by cyclosporin and another (n = 17) receiving cyclosporin and then placebo. Disease activity, extent of disease, sleep and itch, topical steroid use, and adverse events were assessed every two weeks. Both extent and activity of dermatitis were significantly improved (p less than 0.001) as were subjective measures of disease. 20 patients receiving cyclosporin reported adverse events compared with 8 taking placebo, although no patient required withdrawal from the study. Cyclosporin therapy led to an increase in the mean serum urea, creatinine, and bilirubin concentrations, although only the rise in bilirubin was significant (p = 0.001). Our results confirm that cyclosporin is a safe and effective short-term treatment for severe, refractory atopic dermatitis.

Sebaceous carcinoma: an unusual cause of a rapidly enlarging rhinophyma.

We describe a patient who developed sebaceous carcinoma within a long-standing rhinophyma with rapid enlargement of the lesion. We believe the development of this tumour was a random occurrence but the possibility of tumour development should be considered in any rhinophyma showing a rapid increase in size.

Taking the 'sting' out of local anaesthetics.

In order to investigate factors influencing the discomfort caused by the injection of different lignocaine preparations, a randomized, double-blind comparison of paired injections was performed in 32 patients. In all subjects 2% plain lignocaine was found to be more painful than 0.5% plain lignocaine. Lignocaine with adrenaline 1:200,000 was found to be significantly more painful than plain lignocaine. The presence of sodium metabisulphite (the antioxidant in commercial adrenalized lignocaine) significantly increased the discomfort. Neutralization of acidic 0.5% lignocaine (pH 4.7) reduced the discomfort caused in 44% of patients, but this was not statistically significant.

A modified rhombic transposition flap and its application in dermatology.

A modified rhombic transposition flap based around a circular primary defect is described. We have found it to be a versatile design that produces good cosmetic results with a low incidence of postoperative complications. It has become the most frequently used transposition flap in our dermatologic practice.

The use of meshed advancement flaps in the treatment of lesions of the lower leg.

We describe the use of meshed local advancement flaps to repair surgical defects of the lower leg. The procedure produces a lattice of small cutaneous defects that heal rapidly by second intention. The technique is simple to perform and is suitable for large defects of the lower leg. Only minimal supervision is required post-operatively, and the wound causes virtually no pain.

Smoking, eicosanoids and ulcerative colitis.

In this study, which is the first of its kind using normal tissue samples that are very difficult to obtain, we have investigated the hypothesis that smoking protects against ulcerative colitis by altering the colonic mucosal formation of prostaglandins and related substances. Colonic mucosa biopsied from healthy young men produced prostaglandin E, 6-keto-PGF1 alpha (formed from PGI2), leukotriene B4 and leukotriene C4/D4/E4 as determined by radioimmunoassay. With each substance, the median yield was lower in the group of smokers who smoked 3 cigarettes in the 2 h before biopsy, than in the non-smokers. However, with each eicosanoid the statistical probability approached only the 10% level, but the fact that the trend was the same for all eicosanoids somewhat strengthens the possibility of a real difference between the groups.

How much disability is caused by acne?

One-hundred patients completed a questionnaire designed to assess the disability resulting from acne; patient acne severity was also graded clinically. Ten questions which correlated strongly with clinical acne severity were used to form an Acne Disability Index (ADI). This ADI correlated with the severity of facial acne (r = 0.246, P less than 0.01), chest acne (r = 0.347, P less than 0.001) and back acne (r = 0.436, P less than 0.001). Measures were made of the financial value to patients of acne treatment: when hypothetically offered either a cure for their acne or 500 pounds, 87% of patients preferred the treatment rather than the money. All 13 patients who stated a preference for the 500 pounds had minimal acne. There is no correlation between the clinical grading of acne and the amount patients would be prepared to pay for a hypothetical cure but there is a correlation between the acne disability score and the amount patients would pay (r = 0.229, P less than 0.05).

Resolution of atopic dermatitis in a patient treated with cyclosporin.

There are theoretical reasons to anticipate a beneficial action of cyclosporin in atopic dermatitis. We describe a patient with severe atopic dermatitis who responded dramatically while receiving cyclosporin for the treatment of lymphoma. Cyclosporin may have a useful role in patients with resistant atopic dermatitis.

A patient with Tay's syndrome.

A 4-year-old girl with Tay's syndrome had the typical features of congenital ichthyosis and the peculiar anomaly of hair growth, trichothiodystrophy. Her hair shafts were brittle and showed alternating light and dark banding when examined microscopically between polarizing filters. Her hair cystine content was 4.6% (control 8.4%).
