Late relapses in leprosy patients in Brazil: 10-year post-trial of uniform multidrug therapy (U-MDT/CT-BR).

BACKGROUND: Leprosy is a neglected dermato-neurologic, infectious disease caused by Mycobacterium leprae or M. lepromatosis. Leprosy is treatable and curable by multidrug therapy/MDT, consisting of 12 months rifampicin, dapsone and clofazimine for multibacillary/MB patients and for 6 months for paucibacillary/PB patients. The relapse rate is considered a crucial treatment outcome. A randomized Controlled Clinical Trial (U-MDT/CT-BR) conducted from 2007‒2012 compared clinical outcomes in MB patients after 12 months regular MDT/R-MDT and 6 months uniform MDT/U-MDT in two highly endemic Brazilian areas. OBJECTIVES: To estimate the 10 years relapse rate of MB patients treated with 6 months U-MDT. METHODS: The statistical analyses treated the data as a case-control study, sampled from the cohort generated for the randomized trial. Analyses estimated univariate odds ratio and applied logistic regression for multivariate analysis, controlling the confounding variables. RESULTS: The overall relapse rate was 4.08 %: 4.95 % (16 out of 323) in the U-MDT group and 3.10 % (9 out of 290) in the regular/R-MDT group. The difference in relapse proportion between U-MDT and R-MDT groups was 1.85 %, not statistically significant (Odds Ratio = 1.63, 95 % CI 0.71 to 3.74). However, misdiagnosis of relapses, may have introduced bias, underestimating the force of the association represented by the odds ratio. CONCLUSIONS: The relapse estimate of 10 years follow-up study of the first randomized, controlled study on U-MDT/CT-BR was similar to the R-MDT group, supporting strong evidence that 6 months U-MDT for MB patients is an acceptable option to be adopted by leprosy endemic countries worldwide.

Phototherapy.

Of all the therapeutic options available in Dermatology, few of them have the history, effectiveness, and safety of phototherapy. Heliotherapy, NB-UVB, PUVA, and UVA1 are currently the most common types of phototherapy used. Although psoriasis is the most frequent indication, it is used for atopic dermatitis, vitiligo, cutaneous T-cell lymphoma, and cutaneous sclerosis, among others. Before indicating phototherapy, a complete patient assessment should be performed. Possible contraindications should be actively searched for and it is essential to assess whether the patient can come to the treatment center at least twice a week. One of the main method limitations is the difficulty that patients have to attend the sessions. This therapy usually occurs in association with other treatments: topical or systemic medications. Maintaining the regular monitoring of the patient is essential to identify and treat possible adverse effects. Phototherapy is recognized for its benefits and should be considered whenever possible.

Systemic sporotrichosis in an alcoholic patient.

A 44-year-old male patient presented with nodules that evolved with inflammation, following drainage of seropurulent secretion and ulceration. The patient had a 6 year-history of alcohol addiction and reported contact with cats. At the physical examination, the patient had skin-colored and erythematous nodules, and ulcers covered with thick, blackened crusts on the face, trunk and limbs. A culture of a nodule fluid revealed growth of Sporotrix sp. He also had pulmonary involvement and therefore the disease was classified as systemic sporotrichosis, a rare form that usually affect patients infected with HIV. Chronic alcohol abuse was considered the factor of immunosuppression for the patient.

Visita Domiciliar no Território da UBS L 01 Valparaíso

A Unidade Básica de Saúde (UBS) L 01 fica localizada na comunidade Valparaíso, bairro Jorge Teixeira, na cidade de Manaus. Possui cerca de 3600 usuários cadastrados. O território de abrangência possui diversos problemas, como falta de limpeza adequada e moradias em lugares inapropriados. Entre as queixas principais, se destacam hipertensão arterial sistêmica, diabetes mellitus e cefaleia tensional. No cotidiano da UBS, há o clube da gestante, prática abordada para criação de maior vínculo com as usuárias e obtenção de melhores resultados no pré-natal, parto e puerpério. As visitas domiciliares são realizadas às segundas-feiras e torna maior o vínculo usuário-equipe, além de alcançar assistência aos pacientes impossibilitados de comparecer à UBS. Como intervenção na comunidade, optou-se pela realização do projeto de intervenção Monitoramento e Sistematização da Assistência ao paciente com Hipertensão Arterial Sistêmica na UBS L 01 Valparaíso, com o intuito de obter um controle pressórico adequado, bem como prevenir as lesões em outros órgãos. A experiência de atuar em Atenção Primária à Saúde (APS) é fortemente enriquecedora para qualquer profissional de saúde em múltiplos aspectos, tanto clínicos quanto de gestão.
