Lyme borreliosis: investigation to identify cutaneous features among patients who attend the Rio de Janeiro University Hospital / Investigaçöes para identificar manifestaçöes cutâneas em pacientes que såo atendidos no Hospital Universitário do Rio de Janeiro

Background: Lyme borreliosis (LB) is a systemic disease with dermatological manifestations. We investigated the prevalence of this disease in patients at the Hospital of the Federal University of Rio de Janeiro. Material and methods: A series of 204 suspected patients with clinical symptoms and epidemiological data affirmative for the disease were investigated for LB with serology, histopathology and immunohistochemistry associated. Results: In this group of suspected LB patients, serological positivity with IFABb was 33,50 per cent while it was 29,41 per cent among controls. Positivity with ElisaBb was 35,48 per cent. The "G" statistic test was >0,5. We observed the following clinical manifestations: 33 annular erythemas; 2 benign lymphocytic infiltration of the skin; 3 lymphocytoma cutis; 1 urticaria; 9 morphea; 1 systemic progressive sclerosis; 3 lichen sclerosus et atrophicus; 1 eosniphilic fasciitis; 1 edema; 1 purpuric and pigmented dermatitis; 5 arthralgias; 1 polineuropathy; 3 neuralgias and 1 AV heart block. Histopathological and immunohistochemical examinationsdid not identify the etiological agent Bb in any case. Conclusion: 1 - Cutaneous manifestations were the predominating clinical symptons among suspected patients Lb; 2 - The serological test (IFABb) utilized did not help Lyme disease diagnosis. Our controls are above the percentage in endemic areas, and Rio de Janeiro may be one such area; 3 - Serological tests for syphilis should be done at the same time as the serological antiBb test to detect false positive readings

Erupçäo polimorfa à luz solar: diagnóstico clínico e laboratorial / Polymorphous light eruption: clinical and laboratory diagnosis

Säo estudados 10 pacientes com erupçäo polimorfa à luz solar matriculados no Hospital Universitário da UFRJ no período de 1980 a 1985, avaliando-se os aspectos clínico, histopatológico e o achado da substância de "faixa de luz" (Lichtband) na urina. Os dados de anamnese e o quadro dermatológico foram sugestivos para o diagnóstico da doença em oito dos 10 casos. O infiltrado linfocitário perivascular na derme foi compatível com o diagnóstico clínico em todos os casos, ressaltando-se a necessidade de diagnóstico diferencial com lúpus eritematoso discóide. O achado da substância de "faixa de luz" mostrou sensiblidade de 100% nos casos estudados
