BACKGROUND: Leg ulcers are characterized as tissue loss in the lower extremities, generally caused by vascular dysfunction. OBJECTIVES: Verify the clinical and epidemiological profiles of the population sample with leg ulcers treated at the health centers of Juiz de Fora (Brazil). MATERIAL AND METHODS: 124 leg-wound patients were evaluated between January 1999 and August 2001 and submitted to a clinical protocol. RESULTS: The mean age was 64 years, with females in the majority (65.3%). The mean family composition was 3.7 persons, and family income was around US$200.00 (86.8%). Venous insufficiency (90.3%), systemic arterial hypertension (54%), obesity (20.2%) and diabetes mellitus (16.1%) were the most frequent events associated with the ulcers. An association of venous insufficiency and arterial hypertension was frequent in 43.7% of the sample, and significant (p<0.01) to predisposition to the ulcers. These were classified as venous (79%), hypertensive (15.4%), mixed and other (5.6%). The ulcers were generally localized in the distal third of legs (90%) and considered large (>5 cm) in about 90% of the sample, with means of 8.7 cm and 9.6 cm to vertical and horizontal axes, respectively. The ulcers were accompanied mainly by hyperpigmentation (92.7%), lipodermatosclerosis (68.5%) and varicose veins (66.9%), with a mean duration of 94.2 months and 50% of them recurrent. CONCLUSIONS: The data suggested that leg ulcer is an important chronic disease in the elderly and poor population of Juiz de Fora and region.

FUNDAMENTOS: O Scytalidium spp. é fungo filamentoso, saprobio do solo e plantas, considerado, atualmente, patógeno primário das unhas. A prevalência das infecções ungueais causadas por este fungo vem aumentando nas últimas décadas, embora ainda sejam poucos os trabalhos publicados sobre sua epidemiologia. OBJETIVO: Estudo clínico-epidemiológico dos pacientes portadores de onicomicose por Scytalidium spp. em um hospital universitário do Rio de Janeiro. MÉTODOS: Foram avaliados os dados clínico-epidemiológicos de 30 pacientes com onicomicose por Scytalidium spp. por meio do estudo observacional de 1.295 pacientes que se submeteram a exame micológico ungueal no período de 16 meses. RESULTADOS: A maioria dos pacientes era do sexo feminino (66,6%), a média de idade foi de 56,7 anos e 63,3% eram não-brancos. O nível de escolaridade em 53,3% dos pacientes era o ensino fundamental e a renda familiar predominante foi de 3 a 5 salários mínimos em 36,6% dos entrevistados. Em 90% dos casos, as unhas dos pododáctilos foram acometidas, sendo a alteração clínica mais comum a onicólise (18 pacientes) e em 66,6% dos casos observou-se melanoníquia. O tempo de evolução da doença foi maior do que cinco anos em 43,3% dos casos. Dezenove pacientes (63,3%) já haviam realizado tratamento medicamentoso para o quadro atual. CONCLUSÕES: Os dados mostram que a infecção ungueal pelo Scytalidium spp. é crônica, mais comum no sexo feminino (2:1) e atinge indivíduos adultos. Clinicamente, é semelhante às dermatofitoses. A prevalência na amostra estudada foi de 4,86% e correspondeu a 26,92% dos exames positivos
The results obtained at the 6-month period of follow-up showed marked improvement (96% of clinical improvement and 72% of negative culture) of the patients treated for onychomycosis caused by Neoscytalidium in the three tested groups with no statistical differences between them. Multicentric studies with greater number of patients enrolled are necessary to confirm these results.
The use of tumor necrosis factor antagonists (anti-TNF) has become a usual practice to treat various inflammatory diseases. Although indicated for the treatment of psoriasis, anti-TNF may paradoxically trigger a psoriasiform condition. We present a case of a female patient who, during the use of infliximab for rheumatoid arthritis, developed psoriasis. In an attempt to switch anti-TNF class, we observed a cumulative worsening of the lesions requiring suspension of the immunobiological agent and the introduction of other drugs for clinical control. The therapeutic challenge of this paradoxical form of psoriasis is the focus of our discussion. The use of another anti-TNF in these patients is a matter of debate among experts.
3 Médico Dermatologista voluntário do Serviço de Dermatologia/Resident Volunteer, Dermatology, Universidade do Estado do Rio de Janeiro (UERJ/HUPE), Brasil RESUMO -A dermatite infeciosa é uma dermatite grave, crónica e recidivante associada ao vírus linfotrópico de células T humano tipo 1 (HTLV-1). Embora a maioria dos casos descritos tenha início na infância, casos de dermatite infeciosa em adultos tem sido relatados. O quadro dermatológico mimetiza condições comuns como dermatite seborreica, dermatite atópica, dermatite de contato, impetigo e micose fungóide. Em países endémicos para a infeção por HTLV-1, como o Brasil, é imprescindível que a dermatite infeciosa seja lembrada como diagnóstico diferencial nestes casos. A identificação precoce é importante a fim de evitar a disseminação e proporcionar acompanhamento e tratamento adequados de possíveis complicações associadas ao vírus, como a mielopatia associada ao HTLV ou paraparesia espástica tropical, e a leucemia/linfoma de células T do adulto. Relatamos o caso de dois pacientes do sexo feminino com dermatite infeciosa de início na idade adulta. Para enriquecimento do caso, também apresentamos as fotos da filha de uma das pacientes, com mesmo diagnóstico. PALAVRAS-CHAVE -Brasil; Dermatite; Dermatopatias Virais; Infecções por HTLV-I; Vírus Linfotrópico de Células T Humano Tipo 1. Infectious Dermatitis Associated with HTLV-1 in Adults: Difficult Diagnosis and Important Clinical Management ABSTRACT -Infectious dermatitis is a severe, chronic and relapsing dermatitis, associated with human T-cell lymphotropic virus type 1 (HTLV-1). Although most reported cases have onset in childhood, adult cases of infectious dermatitis have been reported. The dermatological framework mimics common conditions such as seborrheic dermatitis, atopic dermatitis, contact dermatitis, impetigo and mycosis fungoides. In endemic countries for HTLV-1, like Brazil, it is essential that the infectious dermatitis is considered as a differential diagnosis in these cases. Early diagnosis is important
