Squamous cell carcinoma complicating lichen planus is described in 3 patients. In 2, the cancers developed on the lower leg in chronic and hypertrophic lichen planus. In the other case, the cancer complicated lichen planus of the lip mucosa in a smoker. In the two cutaneous cases, the tumour and the adjacent skin showed features of lichen planus, including(More)
One hundred and twenty patients with chronic idiopathic urticaria, who entered a study at five centres (Sheffield, London, Bristol, Cardiff and Leeds) were treated with therapeutic doses of the H1 antagonist chlorpheniramine for 6 weeks. Histamine H1 non-responders (40 patients) were entered into a double-blind study and received chlorpheniramine plus(More)
Of 108 renal transplant recipients (53 men and 55 women) treated with azathioprine (0.8-2.9 mg/kg/day) and prednisolone (10 mg daily), 10 men had actinic keratoses, and five of these had squamous cell carcinoma, on light-exposed areas of skin. The time from transplantation to diagnosis of these skin lesions varied from 1.2 to 9.0 (mean 5.1) years. The(More)
A 61-year-old woman, who was known to have Hailey-Hailey disease, presented with increasing vulval soreness. Biopsy showed vulval intraepithelial neoplasia (VIN) 3 and subsequent histology from a vulvectomy specimen showed extensive VIN with early invasive squamous cell carcinoma. This may be another example of chronic inflammation of the vulval area(More)
Psoralen photochemotherapy [psoralen ultraviolet A (PUVA)] plays an important part in dermatological therapeutics, being an effective and generally safe treatment for psoriasis and other dermatoses. In order to maintain optimal efficacy and safety, guidelines concerning best practice should be available to operators and supervisors. The British(More)
Eighteen adults with extensive atopic dermatitis, resistant to conventional treatment, were treated by hypnotherapy, with statistically significant benefit (P < 0.01) measured both subjectively and objectively, which was maintained at up to 2 years where results were available. Twenty children with severe, resistant atopic dermatitis were treated by(More)
The plasma levels of 8-methoxypsoralen (8-MOP) were determined in 18 patients on PUVA treatment for their psoriasis and in two control volunteers. Seven of the patients were on oral therapy and 13 having bath treatment. The plasma levels of 8-MOP were determined up to 6 h after treatment and varied between less than 10 ng/ml and 360 ng/ml for the orally(More)
Although callosities of the plantar skin are common and often disabling, little is known of their pathology or the reasons for their persistence. In this study plantar epidermal structure and cell renewal were investigated in patients with callosities and normal, age-, sex- and site-matched control subjects. Tritiated thymidine autoradiographic labeling(More)
Activation of guanine nucleotide-binding protein (G protein)-coupled receptors is believed to involve conformational change that exposes a domain for G protein coupling at the cytosolic surface of the helical confluence, although the mechanisms for achieving this are not well understood. This conformational change can be achieved by docking a diverse(More)
