Figueiredo, A; Massa, A; Picoto, A; Soares, AP; Sousa-Basto, A; Lopes, C; Resende, C; Rebelo, C; Brandão, FM; Marques-Pinto, G; Schonenberger de Oliveira, H; Selores, M; Gonçalo, M; Bello, MTO Portuguese Acne Advisory Board (PAAB), grupo de dermatologistas portugueses que, à semelhança de grupos congéneres internacionais, tem dedicado particular atenção à definição de linhas de orientação para o tratamento da acne, pretende que o presente documento constitua uma ferramenta útil na abordagem dos doentes com esta patologia. Elaborou-se um dossier, para educação médica contínua, subdividido em 2 partes: Parte I – etiopatogenia e clínica; Parte II – abordagem terapêutica. Nesta Parte I, revêem-se os principais aspectos da clínica e da fisiopatogenia da acne à luz dos conhecimentos actuais. Discute-se a importância do impacto psicológico e social desta entidade e analisam-se os principais mitos e realidades com ela relacionados. Descrevem-se, sucintamente, as patologias mais relevantes no diagnóstico diferencial das lesões de acne. Enumeram-se as indicações para estudo hormonal, bem como os exames a efectuar nos doentes com esta patologia. The Portuguese Acne Advisory Board (PAAB), a group of Portuguese dermatologists with a special interest in acne, develop, as other international groups in this field, consensus recommendations for the treatment of acne. Overall, the goal is to provide a practice guideline to all physicians dealing with this entity. The continuing medical education dossier was divided in two parts: Part I – etiopathogeny and clinical features; Part II – therapy. This Part I reviews acne pathophysiology, clinical aspects, psychological and social impact and several myths surrounding this disease. Some other entities relevant for the differential diagnosis are described. The need of hormonal evaluation is also discussed
- Cyclosporin A treatment in severe childhood psoriasisPublication . Pereira, TM; Vieira, AP; Fernandes, JC; Sousa-Basto, AThough used occasionally, systemic therapies in severe childhood psoriasis have not been systematically investigated. Cyclosporin A (CysA) is effective in adults with severe psoriasis but there are no extensive data regarding the efficacy and safety of its use in childhood psoriasis. In this paper, we describe six children aged between 11 months and 13 years (average: 7.6 years) treated with CysA microemulsion formulation for severe psoriasis, who had been unresponsive to other treatments. The CysA dose ranged from 2 to 4 mg/kg/day, for periods varying from 8 to 105 weeks (mean: 54 weeks). Dose tapering was gradual after lesion improvement and adjusted according to clinical response. Adjuvant therapy with topical steroids, vitamin D3 ointments, coal tar preparations or anthralin was used in all children. Acitretin was used in three patients for short periods. The children were regularly monitored for serum renal and liver function and blood pressure. Improvement of skin lesions was achieved after between 4 and 30 (mean: 12) weeks of treatment, with complete remission in three children. Relapse of lesions occurred in the other children during CysA reduction, but they responded to a dose increase. The treatment was found to be well tolerated and with no significant side-effects. CysA can be used in carefully selected and monitored patients and may represent an alternative tool for severe episodes of psoriasis in children, when other therapies are unsuccessful.

- Occupational protein contact dermatitis: two case reportsPublication . Rocha, J; Pereira, T; Sousa-Basto, A; Brito, CProtein contact dermatitis (PCD) is a contact dermatitis caused by high-molecular-weight proteins. This entity has been reported with increasing frequency, most commonly as occupational hand dermatitis in food handlers. Clinically, it is characterized by a chronic and recurrent dermatitis with erythema, scaling, and fissures with acute exacerbations occurring a few minutes after contact with offending allergen. We report two cases in confectioners who presented with chronic hand dermatitis.
- Rosacea with extensive extrafacial lesionsPublication . Pereira, TM; Vieira, AP; Sousa-Basto, ARosacea is a very common skin disorder in the clinical practice that primarily affects the convex areas of the face. Extrafacial rosacea lesions have occasionally been described, but extensive involvement is exceptional. In the absence of its typical clinical or histological features, the diagnosis of extrafacial rosacea may be problematic. We describe an unusual case of rosacea with very exuberant extrafacial lesions, when compared with the limited involvement of the face.
- A twenty-year survey of dermatophytoses in Braga, Portugal.Publication . Valdigem, GL; Pereira, T; Macedo, C; Duarte, ML; Oliveira, P; Ludovico, P; Sousa-Basto, A; Leão, C; Rodrigues, FBACKGROUND: Modifications in social habits together with the increase of emigration have contributed not only to increased dermatophytoses but also to an altered etiology. During the last few years, Braga has suffered a radical change from a rural to a cosmopolitan life-style. METHODS: A statistical study of dermatophytoses and the etiology of their causative agents was performed by a retrospective survey carried out among patients of Hospital de São Marcos, Braga, Portugal, from 1983-2002. In this study, a total of 10,003 patients were analyzed. RESULTS: Over this period the frequency of dermatophytoses, as defined by the recovery of a dermatophyte in culture, was found to be 23.6%, whereas nondermatophytic infections accounted for 7.0%. Analysis of the clinical forms and the isolated fungi supports that the dermatophyte species have a predilection for certain body areas (P
