The epidemiological scenario of feline sporotrichosis in Rio de Janeiro, State of Rio de Janeiro, Brazil

Introduction Sporotrichosis is a mycosis affecting both humans and animals. Within the context of the ongoing sporotrichosis epidemic in the State of Rio de Janeiro, Brazil, sick cats plays an important role in the zoonotic transmission. The aim of this study was to update the number of feline cases diagnosed at the Fundação Oswaldo Cruz (2005-2011). Methods The medical records of the cats followed were reviewed; the inclusion criterion was the isolation of Sporothrix spp. in culture. Results In total, 2,301 feline cases were identified. Conclusions These results should alert sanitary authorities to the difficulties associated with sporotrichosis control.

High visceral leishmaniasis mortality rate in Barra Mansa, a new area of visceral leishmaniasis transmission in the State of Rio de Janeiro, Brazil

Introduction Nine cases of visceral leishmaniasis occurred recently in Barra Mansa, State of Rio de Janeiro, with a high mortality rate. Methods We reviewed the medical records of the patients. Results Eight were male; 7 were adults. Patients who died progressed to death quickly and presented with aggravating factors: systemic steroid therapy before diagnosis, bleeding, severe liver involvement, infection, and/or refusal to receive transfusion. Conclusions We warn clinicians to be aware of the emergence of visceral leishmaniasis in new areas and to keep in mind the possibility of atypical clinical pictures and aggravating factors, so timely diagnosis can be made and prompt and adequate treatment can be initiated.

Occurrence of severe dengue in Rio de Janeiro: an ecological study

Introduction This study aimed to analyze the relationship between the incidence of severe dengue during the 2008 epidemic in Rio de Janeiro, Brazil, and socioeconomic indicators, as well as indicators of health service availability and previous circulation of the dengue virus serotype-3 (DENV-3). Methods In this ecological study, the units of analysis were the districts of Rio de Janeiro. The data were incorporated into generalized linear models, and the incidence of severe dengue in each district was the outcome variable. Results The districts with more cases of dengue fever in the 2001 epidemic and a higher percentage of residents who declared their skin color or race as black had higher incidence rates of severe dengue in the 2008 epidemic [incidence rate ratio (IRR)= 1.21; 95% confidence interval (95%CI)= 1.05-1.40 and IRR= 1.34; 95%CI= 1.16-1.54, respectively]. In contrast, the districts with Family Health Strategy (FHS) clinics were more likely to have lower incidence rates of severe dengue in the 2008 epidemic (IRR= 0.81; 95%CI= 0.70-0.93). Conclusions At the ecological level, our findings suggest the persistence of health inequalities in this region of Brazil that are possibly due to greater social vulnerability among the self-declared black population. Additionally, the protective effect of FHS clinics may be due to the ease of access to other levels of care in the health system or to a reduced vulnerability to dengue transmission that is afforded by local practices to promote health.

Outbreak of canine visceral leishmaniasis in Barra Mansa, State of Rio de Janeiro

Introduction In Brazil, visceral leishmaniasis (VL) has spread to various regions. This study reports canine cases of VL in Barra Mansa, where human VL cases were recently reported. Methods Using the human index case, a canine survey was performed by dual-path platform immunochromatography and enzyme-linked immunosorbent assay. Seropositive animals were euthanized. Cultures were collected to detect Leishmania parasites. Results Serological tests detected 141 canine VL cases, and Leishmania chagasi were isolated from 82.2% animals. Conclusions Leishmania chagasi is in circulation in Barra Mansa. This study broadens information on the parasite's distribution in the State of Rio de Janeiro.

Studies on Phlebotominae (Diptera: Psychodidae) in the Campus FIOCRUZ Mata Atlântica, Jacarepaguá, in the City of Rio de Janeiro, Brazil

INTRODUCTION: The presence of American cutaneous leishmaniasis (ACL) in the communities of the Campus FIOCRUZ Mata Atlântica (CFMA) in the City of Rio de Janeiro initiated the investigation of the Phlebotominae fauna in the Atlantic Forest to determine the occurrence of putative ACL vectors associated with the enzootic cycle. METHODS: For 24 consecutive months, sand flies were captured inside the forest and in the border area near the communities. RESULTS: The following sand fly species were identified: Brumptomyia brumpti, Brumptomyia cunhai, Brumptomyia nitzulescui, Lutzomyia edwardsi, Lutzomyia pelloni, and Lutzomyia quinquefer. Other identified sand fly vectors, such as Lutzomyia intermedia (the predominant species), Lutzomyia migonei, Lutzomyia whitmani, Lutzomyia fischeri, and Lutzomyia hirsuta hirsuta, are associated with ACL transmission, and the vector for American visceral leishmaniases (AVL), Lutzomyia longipalpis, was also found. CONCLUSIONS: All sand fly vectors were found in both studied environments except for Lutzomyia whitmani, which was only identified in the forest. This study represents the first identification of Lutzomyia longipalpis in the CFMA, and the epidemiological implications are discussed.

Clinical conditions associated withintestinal strongyloidiasis in Rio de Janeiro, Brazil

INTRODUCTION: Strongyloides stercoralis is a soil-transmitted helminth that produces an infection that can persist for decades. The relationships between certain clinical conditions and strongyloidiasis remains controversial. This study aims to identify the clinical conditions associated with intestinal strongyloidiasis at a reference center for infectious diseases in Rio de Janeiro, Brazil. METHODS: The clinical conditions that were assessed included HIV/AIDS, HTLV infection, cardiovascular diseases, diabetes, obstructive respiratory diseases, viral hepatitis, tuberculosis, cancer, chronic renal disease, nutritional/metabolic disorders, psychiatric conditions, rheumatic diseases and dermatologic diseases. We compared 167 S. stercoralis-positive and 133 S. stercoralis-negative patients. RESULTS: After controlling for sex (male/female OR = 2.29; 95% (CI): (1.42 - 3.70), rheumatic diseases remained significantly associated with intestinal strongyloidiasis (OR: 4.96; 95% CI: 1.34-18.37) in a multiple logistic regression model. With respect to leukocyte counts, patients with strongyloidiasis presented with significantly higher relative eosinophil (10.32% ± 7.2 vs. 4.23% ± 2.92) and monocyte (8.49% ± 7.25 vs. 5.39% ± 4.31) counts and lower segmented neutrophil (52.85% ± 15.31 vs. 61.32% ± 11.4) and lymphocyte counts (28.11% ± 9.72 vs. 30.90% ± 9.51) than S. stercoralis-negative patients. CONCLUSIONS: Strongyloidiasis should be routinely investigated in hospitalized patients with complex conditions facilitate the treatment of patients who will undergo immunosuppressive therapy. Diagnoses should be determined through the use of appropriate parasitological methods, such as the Baermann-Moraes technique.

Crime e doença psiquiátrica: perfil da população de um hospital de custódia no Rio de Janeiro

OBJETIVOS: Estudar a população internada em um hospital de custódia no Rio de Janeiro quanto a aspectos demográficos, diagnósticos e criminais. MÉTODOS: Todos os internos cumprindo medida de segurança detentiva no Hospital de Custódia e Tratamento Psiquiá­trico Heitor Carrilho, em dezembro de 2007, (n = 177) foram avaliados pelo censo sociodemográfico aplicado por psiquiatras da instituição e tiveram seus prontuários analisados quanto a diagnóstico, tratamento psiquiátrico prévio e tipo de crime. Foi avaliada a relação entre vítima e perpetrador nos homicídios. RESULTADOS: A população é preferencialmente masculina (80%), solteira (72%), com 30 a 39 anos de idade (34%), baixa escolaridade (69%) e inativa (56%). Os diagnósticos mais prevalentes foram transtornos psicóticos (67%), seguidos por retardo mental (15,2%), transtornos em virtude de uso de substâncias psicoativas (7,3%), de personalidade (4,5%) e outros (6,2%). A maioria (71%) já havia recebido tratamento psiquiátrico prévio. O homicídio foi o crime mais comum (44%), seguido por crimes contra o patrimônio (26%), crimes sexuais (11%), crimes relacionados a entorpecentes (11%) e outros. O homicídio intrafamiliar predominou entre os psicóticos e os portadores de retardo mental. Os últimos cometeram proporcionalmente mais crimes sexuais do que os primeiros. CONCLUSÃO: O perfil da população foi compatível com o descrito para outras populações de internos em hospitais de custódia no país.

É a cardiomiopatia hipertrófica apical vista em uma amostra na cidade do Rio de Janeiro similar à encontrada no oriente?

OBJETIVO: Investigar a existência de diferença na forma de apresentação clínica e evolutiva da cardiomiopatia hipertrófica apical (CMHA), vista em uma amostra na cidade do Rio de Janeiro e a observada no oriente, onde foi descrita. MÉTODOS: Entre 156 pacientes com cardiomiopatia hipertrófica diagnosticados em nossa instituição, foram identificados 13 (8,34%) com a forma apical, sendo estudadas as suas manifestações clínicas, os meios de diagnóstico e a sua evolução. RESULTADOS: Eram 8 homens e 5 mulheres, com idades entre 19 a 75 anos, todos da raça branca, a maioria sintomática. O eletrocardiograma revelou ondas T gigantes em precordiais em 10 pacientes (76,92%), o ecocardiograma (ECO), a presença de hipertrofia apical em todos os casos, sendo em 10 (76,92%) restrita a ponta do ventrículo esquerdo (VE), em dois (15,4%) a ponta do ventrículo direito (VD) e, em 1 (7,68%), acometendo ambos os ventrículos. A cineventriculografia confirmou os achados do ECO. A evolução variou de 6 a 264 meses (x=95,4). Ocorreram dois óbitos (15,4%) em pacientes com o comprometimento associado ao VD, devido ao aumento significativo da dimensão dos átrios, ocorrência de fibrilação atrial, insuficiência valvar mitral e/ou tricúspide e tromboembolismo. Entre os vivos, a paciente com acometimento do VD evolui com restrição diastólica, e os restantes com lesão localizada do VE , 9 estão assintomáticos em uso de propranolol (8) ou amiodarona (1) e um permanece assintomático sem medicação. CONCLUSÃO: presentação, diagnóstico e evolução, porém notamos em 3 pacientes ( 23,08%) o acometimento da ponta do VD, não descrito no oriente, mas com péssimo prognóstico evolutivo.

Socioeconomic aspects of spousal concordance for hypertension, obesity, and smoking in a community of Rio de Janeiro, Brazil

OBJECTIVE: The present study aims to evaluate the environmental role in the distribution of hypertension, obesity, and smoking and spousal concordance for the presence/absence of these 3 cardiovascular risk factors. METHODS: A cross-sectional study was conducted in a community in Rio de Janeiro, Brazil. The households were randomly selected. Odds ratios were estimated to measure spousal concordance, across socioeconomic levels.. RESULTS: Overall a significant aggregation of all 3 risk factors was present. The crude odds ratio for hypertension was 1.78 (95%CI=1.02-3.08); for obesity, it was 1.80 (95%CI=1.09-2.96); and for smoking, it was 3.40 (95% CI=2.07-5.61). The spousal concordance for hypertension decreased significantly (p<0.001) from the lower to the higher educational level. In the case of obesity and smoking, the opposite was observed, although p-values for the linear trend were 0.10 and 0.08, respectively. CONCLUSION: In lower socioeconomic levels, couples are more concordant for hypertension and discordant for smoking. For hypertension and smoking, education seems to be a discriminant stronger than income, but for obesity the 2 socioeconomic indicators seem to represent different aspects of the environmental determinants of risk factor distribution.

Acute myocardial infarction: clinical and epidemiological profile and factors associated with in-hospital death in the municipality of Rio de Janeiro

OBJECTIVE: To study the factors associated with the risk of in-hospital death in acute myocardial infarction in the Brazilian public health system in Rio de Janeiro, Brazil. METHODS: Sectional study of a sample with 391 randomly drawn medical records of the hospitalizations due to acute myocardial infarction recorded in the hospital information system in 1997. RESULTS: The diagnosis was confirmed in 91.7% of the cases; 61.5% males; age = 60.2 ± 2.4 years; delta time until hospitalization of 11 hours; 25.3% were diabetic; 58.1% were hypertensive; 82.6% were in Killip I class. In-hospital mortality was 20.6%. Thrombolysis was used in 19.5%; acetylsalicylic acid (ASA) 86.5%; beta-blockers 49%; angiotensin-converting enzyme (ACE) inhibitors 63.3%; calcium channel blockers 30.5%. Factors associated with increased death: age (61-80 years: OR=2.5; > 80 years: OR=9.6); Killip class (II: OR=1.9; III: OR=6; IV: OR=26.5); diabetes (OR=2.4); ventricular tachycardia (OR=8.5); ventricular fibrillation (OR=34); recurrent ischemia (OR=2.7). The use of ASA (OR=0.3), beta-blockers (OR=0.3), and ACE inhibitors (OR=0.4) was associated with a reduction in the chance of death. CONCLUSION: General lethality was high and some interventions of confirmed efficacy were underutilizated. The logistic model showed the beneficial effect of beta-blockers, and ACE inhibitors on the risk of in-hospital death.

Prevalence of dyslipidemia and risk factors in Campos dos Goytacazes, in the Brazilian State of Rio de Janeiro

OBJECTIVE: To determine the prevalence of dyslipidemias in adults in the city of Campos dos Goytacazes, in the Brazilian state of Rio de Janeiro, and to identify its relation to risk factors. METHODS: Cross-sectional, population-based, observational study with sampling through conglomerates and stratified according to socioeconomic levels, sex, and age, with 1,039 individuals. Risk factors, familial history, blood pressure, anthropometric measurements, glucose, triglycerides and cholesterol were determined. RESULTS: The following prevalences were observed: of dyslipidemias 24.2%; of hypercholesterolemia, 4.2%; of elevated LDL-C, 3.5%; of low HDL-C, 18.3%; and of hypertriglyceridemia, 17.1%. The following mean levels were observed: cholesterol, 187.6± 33.7 mg/dL; LDL-C, 108.7±26.8 mg/dL; HDL-C, 48.5±7.7 mg/dL; and triglycerides, 150.1±109.8 mg/dL. The following variables showed a positive correlation with dyslipidemia: increased age (P<0.001), male sex (P<0.001), low familial income (P<0.001), familial history (P<0.01), overweight/obesity (P<0.001), waist measure (P<0.001), high blood pressure (P<0.001), and diabetes mellitus (P<0.001). The following variables had no influence on dyslipidemias: ethnicity, educational level, smoking habits, and sedentary lifestyle. CONCLUSION: The frequency of lipid changes in the population studied was high, suggesting that measures for the early diagnosis should be taken, in association with implementation of programs for primary and secondary prevention of atherosclerosis.

Letalidade por doenças isquêmicas do coração no Estado do Rio de Janeiro no período de 1999 a 2003

OBJETIVO: Estimar a letalidade nos procedimentos de doenças isquêmicas do coração (DIC) aguda e crônica e por revascularização miocárdica (RVM) e angioplastia coronariana (AC) nos hospitais cadastrados no SIH/SUS (Sistema de Informações Hospitalares/Sistema Único de Saúde) no Estado do Rio de Janeiro (ERJ), de 1999 a 2003. MÉTODOS: Os procedimentos considerados de RVM e de AC provieram do Datasus. As taxas foram padronizadas por sexo, idade e gravidade de doença, tendo como padrão todos os procedimentos de alta complexidade cardiovascular, realizados no ERJ em 2000. Os grupos de DIC são: angina, infarto agudo do miocárdio, outras DIC agudas e DIC crônicas. RESULTADOS: As letalidades por angina, IAM, outras DIC agudas e DIC crônicas foram de 2,8%, 16,2%, 2,9% e 3,9%, respectivamente, no ERJ. As taxas de letalidade, ajustadas por idade, sexo e grupo diagnóstico, nas RVM e AC foram elevadas, variando entre 1,9% e 12,8% nas RVM, e atingindo 3,2% nas AC, e de 2,3% e 11,1%, quando o tratamento clínico era realizado. CONCLUSÃO: As RVM e AC no tratamento das DIC no ERJ vêm aumentando progressivamente. A letalidade esteve acima do desejável, principalmente nas internações por DIC crônicas (5,4% e 1,7%, respectivamente). O tratamento clínico otimizado parece boa opção terapêutica, reservando-se as RVM e AC para os casos de pior prognóstico. A letalidade no IAM com tratamento clínico foi semelhante à existente quando não se utilizam trombolíticos (16,7%).

Letalidade e complicações da cirurgia de revascularização miocárdica no Rio de Janeiro, de 1999 a 2003

FUNDAMENTO: A cirurgia de revascularização do miocárdio (RVM) é um procedimento consolidado no tratamento das doenças isquêmicas do coração (DIC), requerendo constante avaliação. OBJETIVO: Avaliar a qualidade na RVM, através das características clínicas dos pacientes, taxas de letalidade até um ano após a alta hospitalar, causas básicas de morte e complicações pós-operatórias, em quatro hospitais públicos do Município do Rio de Janeiro, de 1999 a 2003. MÉTODOS: Foram selecionados aleatoriamente prontuários de pacientes submetidos à RVM. Informações sobre características clínicas, complicações e óbitos foram coletadas retrospectivamente dos prontuários e das declarações de óbitos. As taxas de letalidade foram estimadas nos períodos intra-hospitalar e até um ano pós-alta. RESULTADOS: As prevalências das características pré-operatórias foram: mulher: 31,9%, hipertensão arterial: 90,7%, dislipidemia: 67,4%, diabete: 37,2%, tabagismo: 22,9%, obesidade: 18,3%, doença pulmonar obstrutiva crônica: 8,2%, acidente vascular encefálico prévio: 5,8%, arteriopatia extracardíaca: 12,7%, elevação da creatinina: 4,1%, estado crítico pré-operatório: 3,7%, infarto agudo do miocárdio recente: 23,5%, angina instável: 40,8%, síndrome coronariana aguda: 50,0%, RVM prévia: 2,4%, disfunção ventricular esquerda: 27,3%, lesão de tronco da coronária esquerda: 3,9% e associada com lesão em outro sistema: 19,8%. As taxas de letalidade nos hospitais variaram de 7,0% a 14,3% no período intra-hospitalar e de 8,5% a 20,2% até um ano pós-alta. As DIC representaram as causas de mais de 80% dos óbitos. O grupo de complicações pós-operatórias mais frequente foi de hemorragia ou baixo débito pós-procedimento. Sessenta por cento dos óbitos apresentaram cinco ou mais complicações enquanto que 40% dos sobreviventes nenhuma. CONCLUSÃO: As taxas de letalidade e de complicações foram elevadas. Mesmo nos sobreviventes as complicações foram mais frequentes do que o esperado.
