ABSTRACT

Abstract

In Brazil, visceral Leishmaniasis is caused by Leishmania chagasi. The development of cutaneous lesions in visceral leishmaniasis patients has been described in two different clinical contexts. Patients with compromised immunity can develop skin lesions as a direct consequence of a current visceral disease. Equally, patients with a history of kala-azar and progressive, immune improvement occasionally develop skin lesions as a consequence of immune reconstitution infl ammatory syndrome. These cases manifest in similar fashion to the classic form of post-kala-azar dermal Leishmaniasis. We describe different cases that exemplify these two clinical presentations.

ABSTRACT

A hidroxiureia é um derivado hidroxilado da ureia utilizado em diversas desordens hematológicas. Inúmeras alterações cutâneas, porém raras, são relatadas após seu uso prolongado. A patogênese das mesmas não está bem esclarecida, porém, sugere-se que a droga tenha uma ação tóxica direta sobre a pele. Descrevemos um homem de 75 anos, branco, com diagnóstico de Policitemia Vera que, ao longo de 11 anos de tratamento com hidroxiureia, evoluiu com várias lesões cutâneas: hiperpigmentação da pele, lesões atróficas em antebraços, melanoníquia longitudinal das 20 unhas, úlcera em antebraço direito, xerose cutânea, ictiose em pernas e carcinoma espinocelular no pavilhão auricular direito. Até o momento, os relatos na literatura descrevem pouca diversidade de lesões nos pacientes acometidos.


Hydroxyurea is an hydroxylated urea derivative used in many myeloproliferative disorders. Many, but unusual cutaneous disorders are related after its prolonged use. Their pathogenesis is not clear, but it is suggested that there is direct toxicity of the drug on the skin. We described a white, 75-year old man with diagnosis of Polycythemia Vera that in 11 years of treatment developed many cutaneous lesions: skin hyperpigmentation, atrophic lesions on forearms, longitudinal melanonychia of 20 nails, right forearm ulcer, cutaneous xerosis, ichthyosis and auricular spinocellular carcinoma. At this moment, the literature reports describe little diversity of lesions in affected patients.

ABSTRACT

Apesar da redução na incidência de tétano acidental no Brasil, não houve queda significativa na letalidade. Nesta série de casos, comparamos a letalidade antes e após o estabelecimento padrão de manejo em unidade de terapia intensiva do paciente com tétano no Hospital Universitário Oswaldo Cruz, no período de 1981 a 2004. Em 24 anos, foram internados 1.971 pacientes e antes do manejo em Unidade de terapia intensiva a letalidade era de 35 por cento. Durante 1997 foi instituída a unidade de terapia intensiva para assistência dos pacientes com tétano, e de 1998 a 2004, a letalidade caiu para 12,6 por cento, OR= 0,27 (IC95 por cento= 0,18- 0,39); p<0,001. Esta tendência foi evidenciada em todas as faixas etárias e em ambos os sexos. A centralização da assistência a esses pacientes em um único serviço especializado com Unidade de terapia intensiva de forma precoce, portanto, tem sido decisiva na redução da letalidade, por contar com a vasta experiência da equipe de saúde no manejo do tétano e melhor tratamento sintomático, antecipando as graves complicações da doença.


Despite reductions in the incidence of accidental tetanus cases in Brazil, there has not been any significant decrease in its mortality. In this case series, the mortality rates before and after establishing standard management practices for tetanus patients in the intensive care unit at the Oswaldo Cruz University Hospital are compared over the period from 1981 to 2004. Over these 24 years, 1.971 patients were admitted. Before establishing the intensive care unit management, the mortality rate was 35 percent. The Intensive care unit for attending to tetanus patients was established in 1997. From 1998 to 2004, the mortality rate fell to 12.6 percent: OR = 0.27 (95 percent CI = 0.18-0.39); p < 0.001. This trend was seen in all age groups and both sexes. The centralization of attendance for these patients into a single specialized service with early treatment in an intensive care unit has therefore been decisive in reducing the mortality rate. This service can count on the medical team's vast experience of tetanus management, with better treatment of symptoms that forestalls the serious complications from this disease.
