Necrotizing soft tissue infection of the breast: Case report and literature review

Background: Necrotizing soft tissue infection (NSTI) is characterized by progressive infectious gangrene of the skin and subcutaneous tissue. Its treatment involves intensive care, broad-spectrum antibiotic therapy, and full debridement. Methods: We present two cases of NSTI of the breast, adding these cases to the 14 described in the literature, reviewing the characteristics and evolution of all cases. Case Report: On the fourth day after mastectomy, a 59-year-old woman with ulcerated breast cancer developed Type I NSTI caused by Pseudomonas aeruginosa, which had a favorable evolution after debridement and broad-spectrum antibiotics. The second patient was a 57-year-old woman submitted to a mastectomy and axillary dissection, who had recurrent seromas. On the 32nd post-operative day, after a seroma puncture, she developed Type II NSTI caused by β-hemolytic streptococci. She developed sepsis and died on the tenth day after debridement, intensive care, and broad-spectrum antibiotics. The cases are the first description of breast NSTI after mammary seroma aspiration and the first report of this condition caused by P. aeruginosa. Conclusion: Necrotizing soft tissue infection is rare in breast tissue. It frequently is of Type II, occurring mainly after procedures in patients with breast cancer. The surgeon's participation in controlling the focus of the infection is of fundamental importance, and just as important are broad-spectrum antibiotic therapy and support measures, such as maintenance of volume, correction of electrolytic disorders, and treatment of sepsis and septic shock. Once the infection has been brought under control, skin grafting or soft tissue flaps can be considered. The mortality rate in breast NSTI is 18.7%, all deaths being in patients with the fulminant Type II form. Surgical oncologists need to be alert to the possibility of this rare condition. © 2012, Mary Ann Liebert, Inc.

Policy Brief: an assessment of the economic and social impacts of climate change on the coastal and marine sector in the Caribbean

Caribbean policymakers are faced with special challenges from climate change and these are related to the uncertainties inherent in future climate projections and the complex linkages among climate change, physical and biological systems and socioeconomic sectors. The impacts of climate change threaten development in the Caribbean and may well erode previous gains in development as evidenced by the increased incidence of climate migrants internationally. This brief which is based on a recent study conducted by the Economic Commission for Latin America and the Caribbean (LC/CAR/L.395)1 provides a synthesis of the assessment of the economic and social impacts of climate change on the coastal and marine sector in the Caribbean which were undertaken. It provides Caribbean policymakers with cutting-edge information on the region’s vulnerability and encourages the development of adaptation strategies informed by both local experience and expert knowledge. It proceeds from an acknowledgement that the unique combination of natural resources, ecosystems, economic activities, and human population settlements of the Caribbean will not be immune to the impacts of climate change, and local communities, countries and the subregion as a whole need to plan for, and adapt to, these effects. Climate and extreme weather hazards related to the coastal and marine sector encompass the distinct but related factors of sea level rise, increasing coastal water temperatures, tropical storms and hurricanes. Potential vulnerabilities for coastal zones include increased shoreline erosion leading to alteration of the coastline, loss of coastal wetlands, and changes in the abundance and diversity of fish and other marine populations. The study examines four key themes in the analysis: climate, vulnerability, economic and social costs associated with climate change impacts, and adaptive measures.

Prevalência de anticorpos anti-vírus da hepatite A em escolares no município de Porto Velho, Rondônia

A avaliação da prevalência de anticorpos contra o vírus da Hepatite A foi realizada no período de setembro a dezembro de 2000, em 185 escolares de níveis sócio-econômicos distintos, na faixa etária entre seis e quinze anos, em duas escolas no município de Porto Velho, Rondônia, utilizando teste imunoenzimático comercial (DiaSorin) para detecção de anticorpos anti-VHA Totais e IgM. Foram avaliados 90 escolares de nível sócio-econômico médio e alto, procedentes de Escola Privada, e 95 de baixo nível sócio-econômico, de Escola Pública. Dos 90 escolares da Escola Privada, 45 (50%) apresentaram positividade ao teste para detecção de anticorpos anti-VHA Totais e deste, 4 (8,9%) foram soropositivos ao anti-VHA IgM, enquanto na Escola Pública, dos 95 estudantes, 90 (94,7%) apresentaram anticorpos anti-VHA Totais e destes, apenas 1 (1,1%) apresentou anticorpos anti-VHA IgM (p< 0,05). As faixas etárias entre 12 e 14 anos na Escola Privada, e 8 e 10 anos na Escola Pública, apresentaram maior prevalência de anticorpos anti-VHA. Não houve diferença significativa de prevalência de anti-VHA entre os sexos, nos dois grupos estudados (p>0,05). Fatores como renda familiar, destino dos dejetos domiciliares e qualidade de água consumida também foram estudados e relacionados à prevalência de anti-VHA, apresentando diferenças significativas entre os grupos. Os resultados deste estudo mostraram que a HVA é endêmica na região, e que, medidas como melhoria nas condições sanitárias do município são necessárias para diminuir a propagação do VHA na população.

Estudo morfológico de microparasitas em Aequidens plagiozonatus Kullander 1984 (Osteiththyes: Cichlidae)

O mercado de peixes ornamentais vem crescendo gradativamente nos últimos anos e com a crescente pressão exercida nos bancos naturais de recursos pesqueiros, busca-se alternativas para a continuidade da produção de pescado, seja através da aqüicultura ou da busca por novos recursos pouco ou até mesmo inexplorado, como e o caso do cara-pix8una, Aequidens plagiozonatus. A partir desse conhecimento é importante a realização de estudos que caracterizem o perfil parasitológico dessas espécies de peixes a fim de verificar e controlar a disseminação de parasitas que geram desequilíbrio nos ecossistemas aquáticos. Por isso, o objetivo deste estudo foi Descrever morfologicamente os microparasitas (microsporídios, mixosporídios e coccidios) encontrados em A. plagiozonatus provenientes do rio Peixe-Boi /PA, através do levantamento de ações parasitárias causadas por microparasitas (microsporídios, myxosporídios e coccidios) com ênfase na morfologia destes. Para isso, foram realizadas 5 coletas, totalizando 100 espécimes, sendo estes necropsiados e tendo seus órgãos analisados. Dos órgãos parasitados foram retirados fragmentos, fixados e processados para microscopia de luz. Foram calculados o Indice hepatossomático dos exemplares e a prevalência parasitaria para cada grupo de parasitas analisados, enfatizando os microparasitas. A partir das observações feitas foram encontrados os 3 filos parasitas: Myxozoa, Microsporidia e Apicomplexa. A prevalência dos microsporídios nos exemplares estudados foi de 100%, dos mixosporidios 18% e dos Apicomplexa de 45%. Nossos dados representam uma importante contribuição para o estudo ictiossanitário em A. plagiozonatus na região, uma vez que qualquer atividade que envolva a extração de recursos naturais deve ser gerenciada por meio de medidas de ordenamento e manejo, para permitir o equilíbrio dos ecossistemas, promovendo o uso sustentável de seus recursos e garantindo a preservação do sistema, a fim de que se possa evitar a propagação e transferência de doenças por meio de animais aquáticos.

Prevalence and genotyping of hepatitis C virus in blood donors in the state of Pará, Northern Brazil

Given the scarcity of epidemiological information on hepatitis C virus (HCV) infection in Northern Brazil, we determined the prevalence and genotypic frequency in blood donors in the state of Pará (PA). Blood samples from all of the blood donors at the Fundação HEMOPA (blood bank of PA) from 2004-2006 were screened for the presence of antibodies to anti-HCV and samples seroreactive to anti-HCV were further tested for HCV RNA using real-time PCR. In total, 116 HCV-RNA samples were genotyped, based on maximum likelihood phylogenetic analyses, using BioEdit, Modelgenerator, PHYML and FigTree software. The population consisted of 242,726 volunteers who donated blood from 2004-2006; the most common subgroup was males between the ages of 18-29 years old (37.30%). Within the whole group, 1,112 blood donors (0.46%) had indeterminate or positive serology; among these, 28.78% were males whose ages ranged from 18-29 years. A diagnosis of chronic HCV infection was confirmed for 304 donors (60.20% males; 66.45% were 30-49 years old), resulting in a prevalence of HCV RNA in 0.13% of the samples (304 of 242,726). HCV genotyping revealed a high frequency of genotype 1 (108/116) followed by genotype 3 (8/116). This study found HCV infection to be relatively infrequent in PA; genotype 1 was most commonly isolated. This information can help guide prevention and control policies aimed at efficient diagnosis and control measures.
