    Notes: Background After treatment of a basal cell carcinoma (BCC) patients are at risk of recurrence of that BCC; also, patients who have had a primary BCC are those who have an increased risk of developing a subsequent primary BCC. However, long-term hospital-based follow-up of all patients would put large strains on the U.K. health service. Objectives To investigate the follow-up intentions of U.K. dermatologists for well-defined facial BCC and to investigate the effect that variations in site and clinical indicators might have on those intentions. Methods A self-completion questionnaire relating to BCC follow-up sent to 388 dermatology consultants and associate specialists in the U.K. had a response rate of 68%. The effects of treatment modality, tumour site, histology, multiple lesions and various patient variables that might alter the likelihood of follow-up were examined. General views on the subject of BCC follow-up were sought. Results Twenty-seven per cent of respondents reported that they would not review further after excision of a ‘well-defined’ BCC from inside a central ‘T’ area on the face; 37% reported that they would review on one occasion; and 36% reported that they review more than once. Conclusions While it is currently not feasible to follow-up all treated BCCs, a strategy to identify and monitor high-risk patients and a system to gather long-term outcome data prospectively are necessary aspects of a national health service. This study illustrates that the first issue is being addressed to some extent, but at the currently reported level of BCC follow-up in the U.K. there is little scope for collecting comprehensive long-term data on outcomes.

    Notes: Tumour necrosis factor alpha (TNF-α) appears important in ultraviolet-induced immunosuppression, suggesting that it is a susceptibility candidate for cutaneous basal cell carcinoma (BCC). We now describe data on the association between TNF microsatellite polymorphisms, first on susceptibility in 202 controls and 133 cases each having two to 30 BCCs, and secondly, within the cases, on BCC numbers. The data show that the proportions of individuals with TNF a1- and a7-containing genotypes were significantly different (P = 0·0271, P = 0·0393, respectively) between cases and controls. Secondly, within the cases, TNF alleles d4 (P = 0·023) and d6 (P = 0·006) alone, and the TNF a2–b4–d5 haplotype (P = 0·007), were significantly associated with the number of BCC lesions. These preliminary data provide the first evidence that TNF microsatellite polymorphism may influence the pathogenesis of multiple BCC.

    Notes: While ultraviolet (UV) exposure is thought to be a major risk factor for basal cell carcinoma (BCC) and squamous cell carcinoma, more recent research has focused on genetic factors predisposing to these cancers. UV constitutes an oxidative stress with generation of free radicals, leading to lipid and DNA damage and gene mutation. It could therefore be hypothesized that individual ability to deal with these products may be important in cutaneous carcinogenesis. It is clear from recent studies that polymorphisms in detoxifying enzyme genes are important in determining susceptibility to skin cancer. The magnitude of effect in BCC is similar to that seen with many other previously described risk factors. However, uncertainties exist regarding the phenotypic consequences of some of these polymorphisms and relevant substrates. This review describes the influence of polymorphisms in detoxifying enzymes in determining susceptibility to skin cancer (in particular to BCC) and give a brief overview of the biochemistry of the detoxification process.

    Notes: Azathioprine has an important role in treatment of many inflammatory dermatoses. In view of the current emphasis on evidence-based medicine, we performed a questionnaire-based survey to establish current practice in the use of azathioprine by consultant dermatologists and associate specialists in the U.K. The response rate was 68%. In contrast with the manufacturer's recommendation, our data provide evidence that azathioprine is useful in the treatment of a wide variety of dermatological diseases. However, there is still a need for controlled trials in some conditions. The most common conditions treated were pemphigoid, pemphigus and atopic eczema. In addition, we found that only 13% of dermatologists prescribe azathioprine according to body weight. Most dermatologists felt that azathioprine was well tolerated. No one tested for thiopurine methyltransferase (TPMT) activity, which is thought to be a predictor of severe myelosuppression. The combination of prescribing azathioprine according to body weight and measuring TPMT activity would optimize efficacy and minimize potential severe myelotoxicity.

    Notes: Acne vulgaris is very common, 85% of teenagers being affected at any one time. In most cases, the disease is mild and patients do not present to the dermatologist. Most are instead treated with over-the-counter products and conventional treatment such as peeling agents or topical and systemic antibiotics. Isotretinoin has revolutionized the treatment of severe acne unresponsive to oral antibiotics. Explosive and very severe acne such as pyoderma faciale, acne conglobata and acne fulminans are rare, the features that distinguish acne fulminans from the other conditions being systemic upset with fever, joint pain, malaise and leucocytosis,1–3 while there have been two reports of the condition associated with erythema nodosum.4,5 The recommended treatment for acne fulminans is a combination of oral steroids and systemic antibiotics, isotretinoin probably not being the treatment of choice.6 We now report a patient who developed acne fulminans and erythema nodosum within 3 weeks of starting isotretinoin and then responded to dapsone without oral steroids.
