Seasonality of the hospitalizations at a dermatologic ward (2007-2017)

Abstract: There is little data in the literature concerning dermatologic admissions. Several diseases are seasonal in incidence and clinical worsening. We performed a survey of hospitalizations in the dermatology ward of a public hospital (April/2007 to May/2017). There were 1790 hospitalizations, whose main diagnoses were infectious dermatoses, neoplasias, psoriasis, bullous diseases and cutaneous ulcers. In winter, there were fewer hospitalizations for bacterial infections and urticaria, but more for leprosy. In summer, there were fewer hospitalizations for systemic and subcutaneous mycoses, but more for zoodermatoses and erythema multiforme. In the fall, more patients were admitted with mycoses. Spring favored urticaria and angioedema, but less cases of erythema multiforme and diabetic foot.

Infecções da pele e de tecidos moles na unidade de terapia intensiva: estudo retrospectivo em um centro terciário / Skin and soft tissue infections in the intensive care unit: a retrospective study in a tertiary care center

RESUMO Objetivo: Descrever o prognóstico, os fatores de risco e a etiologia das infecções da pele e dos tecidos moles na unidade de terapia intensiva. Métodos: Estudo retrospectivo de uma coorte de 1.123 pacientes graves admitidos a uma unidade de terapia intensiva com o diagnóstico de infecção grave de pele ou tecidos moles. Resultados: Foram selecionados 30 pacientes, sendo 20 (66,7%) com fasceíte necrotizante, predominantemente da região perineal; 8 (26,7%) com abscesso cutâneo; e 2 (6,6%) com celulite. A maioria dos pacientes tinha fatores de risco, como imunossupressão e lesões cutâneas. O microrganismo isolado predominante foi Escherichia coli. Pacientes com fasceíte necrotizante na admissão à unidade de terapia intensiva apresentaram mortalidade significativamente maior (55%; p = 0,035), assim como aqueles com maior índice de severidade, choque séptico, parada cardiorrespiratória e leucocitose. Organismos resistentes à antibioticoterapia foram comuns, mesmo na ausência de fatores de risco. Quando presente, o fator de risco mais comum foi o uso prévio de antibiótico. Conclusão: Foram identificados fatores de risco e microrganismos diferentes dos classicamente descritos na literatura, além de elevada mortalidade da fasceíte necrotizante e presença de microrganismos multirresistentes na ausência de fatores de risco. Dada a aparente evolução etiológica das infecções da pele e tecidos moles, a identificação de novos fatores de risco e etiologia pode contribuir para uma terapêutica antimicrobiana mais adequada.

ABSTRACT Objective: To identify factors that may influence outcomes in patients with severe skin and soft tissue infections in the intensive care unit. Methods: A retrospective observational study was conducted in a cohort of 1,123 critically ill patients admitted to an intensive care unit with a primary or secondary diagnosis of severe skin and soft tissues infection between January 2006 and December 2014. Results: Thirty patients were included, 20 (66.7%) of whom were diagnosed with necrotizing fasciitis; in these patients, perineal area involvement was most commonly identified. Abscess was diagnosed in 8 (26.7%) patients, most commonly involving the cervical area. Risk factors such as immunosuppression and previous surgical trauma were commonly observed in this population. The most commonly isolated microorganism was Escherichia coli. Multidrug resistant microorganisms were commonly detected, even in the absence of traditional risk factors; among these patients, previous use of antibiotics was the most common risk factor for drug resistance. The rate of mortality was significantly higher in patients with necrotizing fasciitis (55%, p = 0.035) and associated with disease severity, presence of septic shock, cardiac arrest and leucocytosis. Conclusion: Different risk factors and etiologies of severe skin and soft tissue infections were identified. Necrotizing fasciitis and drug-resistant bacteria were significant predictors of mortality, even in the absence of traditional risk factors. Obtaining a better understanding of trends in the risk factors and microorganisms associated with severe skin infections may help in the determination of prompt treatment and antibiotic choices.

Study of dermatoses in kidney transplant patients / Estudo das dermatoses em pacientes transplantados renais

BACKGROUND: The increasing in the number of kidney transplant recipients has favored, more frequently than before, the emergence of dermatoses and warranted their study through subsequent publications. OBJECTIVES: to evaluate the frequency of dermatoses in kidney transplant recipients. METHODS: kidney transplant recipients with suspected dermatoses between March 1st 2009 and June 30th 2010. RESULTS: 53 patients (28 males and 25 females), aged between 22 and 69 (mean age = 45 years) were evaluated. Most of them came from the cities of Ceilândia, Samambaia and São Sebastião/DF, and had already been transplanted for 5 to 10 years before (37.7%); 62.3% were recipients of living donors and 83% were prednisone-treated. The most prevalent dermatoses were of fungal (45.3%) and viral (39.6%) etiologies. Among the non-melanoma malignant neoplasms, the basal cell carcinoma prevailed (six cases), in spite of the low incidence. Concerning fungal dermatoses, 12 cases of onychomycosis, five of pityriasis versicolor and four of pityrosporum folliculitis were reported. For diagnosis, in most cases (64.2%), laboratory examinations (mycological and histopathological) were performed. CONCLUSION: cutaneous manifestations in kidney transplant recipients are generally secondary to immunosuppression. The infectious dermatoses, especially those of fungal origin, are frequently found in kidney transplant recipients and their occurrence increases progressively according to the time elapsed from the transplantation, which makes follow-up important. .

FUNDAMENTOS: o crescente aumento do número dos transplantados renais tem favorecido o aparecimento mais frequente das dermatoses e permitido o estudo em sucessivos trabalhos. OBJETIVOS: avaliar a frequência das dermatoses em pacientes transplantados renais. MÉTODOS: captação de pacientes transplantados renais durante o período de 1° de março de 2009 a 30 de junho de 2010 com suspeita de dermatoses. RESULTADOS : foram avaliados 53 pacientes (28 homens e 25 mulheres), entre 22 e 69 anos (com uma média de 45 anos), a maioria procedente de Ceilândia, Samambaia e São Sebastião/DF, entre 5 e 10 anos de transplante renal (37,7%), sendo 62,3% receptor de doador vivo e 83% em uso de prednisona. As dermatoses mais prevalentes foram as de etiologia fúngica (45,3%) e viral (39,6%). Das neoplasias malignas não-melanoma, apesar da baixa incidência, predominou o carcinoma basocelular (seis casos). Com relação s dermatoses de origem fúngica, ocorreram 12 casos de onicomicoses, cinco casos de pitiríase versicolor e quatro casos de foliculite pitirospórica. Para realização do diagnóstico, na maioria dos casos (64,2%), foi utilizado os exames laboratoriais ( micológicos e histopatológicos). CONCLUSÃO: as manifestações cutâneas em pacientes transplantados renais são geralmente secundárias imunossupressão. As dermatoses infecciosas, principalmente as de etiologia fúngica, são frequentes em pacientes transplantados renais, e sua ocorrência aumenta progressivamente, conforme o tempo transcorrido, a partir do transplante, sendo importante o acompanhamento. .
