    Notes: In an open, multicentre evaluation carried out in Brazil, Canada and South Africa we have demonstrated that fluconazole 8 mg kg−1 once weekly is effective in tinea capitis caused by Trichophyton and Microsporum species. There were 61 children, aged (mean ± SE) 5·0 ± 0·3 years; weight (mean ± 5·6) 20·0 ± 0·9 kg; 41 males, 20 females; one Asian, 57 Black, one Caucasian and two Hispanic. The organisms were Trichophyton violaceum (33 patients), T. tonsurans (11) and Microsporum canis (17). The extent of tinea capitis at pretherapy was: mild (18 patients), moderate (30) and severe (13). Patients with tinea capitis due to Trichophyton species were initially treated for 8 weeks with an extra 4 weeks of fluconazole if clinically indicated. All 44 patients with tinea capitis due to Trichophyton species were completely cured (clinically and mycologically) when evaluated 8 weeks after completion of active treatment, following 8 weeks of once weekly dosing in 35 patients and 12 weeks of once weekly dosing in nine patients. In Microsporum canis tinea capitis, an extra 4 weeks was administered at week 12 in patients where it was clinically indicated at the time. Sixteen of 17 patients with M. canis tinea capitis were completely cured (clinically and mycologically) when evaluated 8 weeks following the end of treatment when given for 8, 12 and 16 weeks in 12, one and three patients, respectively. Overall, complete cure (clinical and mycological) occurred in 60 of 61 patients at follow-up 8 weeks from the end of therapy. The duration of once weekly fluconazole in the 60 patients was 8 weeks (47 patients), 12 weeks (10 patients) and 16 weeks (three patients), respectively. Clinical adverse effects consisted of a mild, reversible gastrointestinal complaint in three (4·9%) of 61 children. A laboratory abnormality with elevated liver function tests was observed in one (5·9%) of 17 patients; this was asymptomatic, and reversible. No patient discontinued therapy. The data suggest that once weekly fluconazole dosing is effective, safe and associated with high compliance when used to treat tinea capitis.

    Notes: Urticarial lesions may occur as a manifestation vasculitis. We describe a series of patients with recurrent urticaria characterized by persistent weals in which a leucocytoclastic or lymphocytic vasculitis was demonstrated. The spectrum ranged from limited cutaneous involvement to severe systemic disease. The individual lesions were of long duration (over 24 h) in all patients. One had systemic lupus erythematosus, one developed Sjögren's Syndrome and one had recurrent abdominal pain and diarrhoea which coincided with her skin eruption. Therapy was difficult in most cases and some patients required systemic corticosteroids to control their disease.

    Notes: The adverse effects of acne on the psyche have been established in patients from ‘first world’ countries. There has been no in depth study in predominantly black patients from Africa addressing this issue. This was a prospective cross-sectional study of acne patients attending a dermatology unit in KwaZulu-Natal, South Africa. A questionnaire was completed and acne graded by the Global Acne Grading scale. Psychological morbidity and quality of life (QOL) were assessed by the General Health Questionnaire and Dermatology Specific Quality of Life Questionnaires, respectively. We found that clinical severity was not associated with patient perception or psychological distress. The QOL measures such as feelings, social activities, performance at work or school, activities of daily living and overall mental health were found to be associated with distress with associated P-values of 0.0002, 0.0168, 0.0032, 0.033 and 〈 0.0001, respectively. The severity of acne was not associated with psychological distress. Painful and bleeding lesions were associated with distress levels; P = 0.042 and P = 0.019, respectively. In conclusion, South African patients with acne vulgaris suffer significant psychological distress, which affects the quality of their lives.

    Notes: During the period 1985-88, 30 children with a chronic blistering dermatosis were studied. Of these 25 were found to have chronic bullous dermatosis of childhood (CBDC) and five had bullous pemphigoid (BP). No case of dermatitis herpetiformis (DH) was seen in the same period. Except for the difference in immunofluorescence (IMF) there were no definite clinical, histological or therapeutic differences between the two groups. All the children were Africans with the exception of one Indian girl. Their ages ranged from 1 year to 12 years with a mean of 5 years. The females outnumbered the males in a ratio of 3:2.All children had a generalized eruption consisting of large tense blisters arising on normal skin. The blisters were more profuse on the lower trunk, pelvic region and limbs. Face and scalp were also affected. Histological features of BP and DH were seen. Direct IMF in the CBDC patients showed linear deposits of IgA at the basement membrane zone (BMZ) while linear deposits of IgG were seen in the BP group. Complement and IgM were also seen in some cases in both groups. Sixty per cent of the CBDC patients showed IgA BMZ antibodies by indirect IMF. There were no symptoms or signs of malabsorption. Serum vitamin B12 and folate levels were normal. HLA studies showed the B-8 antigen in five of the 20 patients studied. Therapy was difficult in most cases. All patients haemolysed on therapeutic doses of dapsone, sulphapyridine and/or prednisone had to be added. Follow-up was generally poor as six patients failed to return after discharge from hospital. Five CBDC patients are in remission and the rest are still on treatment: eight on dapsone alone, three on dapsone and sulphapyridine and nine on dapsone, sulphapyridine and prednisone.

    Notes: Biopsies from suction blisters raised in three normal volunteers were used as substrate in the indirect immunofluorescence technique to determine the binding site of circulating IgA antibodies in serum from three patients with adult linear IgA disease (LAD), nine with chronic bullous disease of childhood (CBDC), three with childhood cicatricial pemphigoid (CCP), and four with bullous pemphigoid (BP). Direct immunofluorescence was done using suction blisters raised in two patients with LAD and one with CCP.The circulating IgA antibodies in LAD and CBDC bound mainly to the roof of the blister but also to the base, and in CCP they bound only to the base of the blister. The circulating IgG antibodies in BP bound to the roof and base of the blister. These results demonstrate that the antigens in the various linear IgA dermatoses are heterogenous and are localized at different sites. The LAD and CBDC antigens are present in the lamina tucida, and the antigen in CCP is associated with the basal lamina.
