Objective This study describes epidemiological and clinical features of patients with confirmed infection by SARS-CoV-2 diagnosed and treated at Hospital Israelita Albert Einstein , which admitted the first patients with this condition in Brazil. Methods In this retrospective, single-center study, we included all laboratory confirmed COVID-19 cases at Hospital Israelita Albert Einstein , São Paulo, Brazil, from February until March 2020. Demographic, clinical, laboratory and radiological data were analyzed. Results A total of 510 patients with a confirmed diagnosis of COVID-19 were included in this study. Most patients were male (56.9%) with a mean age of 40 years. A history of a close contact with a positive/suspected case was reported by 61.1% of patients and 34.4% had a history of recent international travel. The most common symptoms upon presentation were fever (67.5%), nasal congestion (42.4%), cough (41.6%) and myalgia/arthralgia (36.3%). Chest computed tomography was performed in 78 (15.3%) patients, and 93.6% of those showed abnormal results. Hospitalization was required for 72 (14%) patients and 20 (27.8%) were admitted to the Intensive Care Unit. Regarding clinical treatment, the most often used medicines were intravenous antibiotics (84.7%), chloroquine (45.8%) and oseltamivir (31.9%). Invasive mechanical ventilation was required by 65% of Intensive Care Unit patients. The mean length of stay was 9 days for all patients (22 and 7 days for patients requiring or not intensive care, respectively). Only one patient (1.38%) died during follow-up. Conclusion These results may be relevant for Brazil and other countries with similar characteristics, which are starting to deal with this pandemic.
Introduction: Central venous catheters are fundamental to daily clinical practice. This procedure is mainly performed by residents, often without supervision or structured training. Objective: To describe the characteristics of central venous catheterization and the complication rate related to it. Method: Retrospective cohort study. Adult patients undergoing central venous catheter insertion out of the intensive care unit (ICU) of a teaching hospital were selected from March 2014 to February 2015. Data were collected from medical charts using an electronic form. Clinical and laboratory characteristics from patients, procedure characteristics, and mechanical and infectious complications rates were assessed. Patients with and without complications were compared. Results: Three hundred and eleven (311) central venous catheterizations were evaluated. The main reasons to perform the procedure were lack of peripheral access, chemotherapy and sepsis. There were 20 mechanical complications (6% of procedures). Arterial puncture was the most common. Procedures performed in the second semester were associated with lower risk of complications (odds ratio 0.35 [95CI 0.12-0.98; p=0.037]). Thirty-five (35) catheter-related infection cases (11.1%) were reported. They were related to younger patients and procedures performed by residents with more than one year of training. Procedures performed after the first trimester had a lower chance of infection. Conclusion: These results show that the rate of mechanical complications of central venous puncture in our hospital is similar to the literature, but more attention should be given to infection prevention measures.
Introdução: Tumores estromais gastrointestinais (GIST) são neoplasias raras que se originam das células intersticiais de Cajal. Objetivo: Descrever a experiência do Hospital de Clínicas de Curitiba no tratamento do GIST localizado e avançado, com análise das características clínicas e anatomopatológicas e uso do imatinibe. Método: Estudo retrospectivo com 32 pacientes com diagnóstico por imuno-histoquímica, c-Kit positivo, no período de 2003 a 2008. Resultados: Idade mediana: 66 anos; tamanho mediano do tumor de 8,4 cm; e as localizações mais frequentes foram estômago em 46,9% e intestino delgado em 40,9%. Pacientes com alto risco de agressividade: 37,5%; apresentavam doença localizada no diagnóstico 23 pacientes: 39,1% recaíram e 9 com doença avançada. O seguimento mediano foi de 43,7 meses, com sobrevida global em 5 anos no grupo total de 56,2%. Na doença localizada, a sobrevida global em 5 anos foi de 73,8% e na avançada de 37,5% (p=0,03). Não ocorreu impacto dos fatores prognósticos na sobrevida. Utilizou-se o mesilato de imatinibe em 16 pacientes: 43,8% por metástase inicial, 37,5% recaída a distância, 12,5% recaída local e 6,2% margem comprometida. A sobrevida global com uso do imatinibe mediana foi de 53 meses e a sobrevida livre de primeira progressão de 32,9 meses. Houve boa tolerabilidade ao imatinibe e apenas dois pacientes utilizaram o sunitinibe. Conclusão: A maioria dos tumores era grande, de localização gástrica e de alto risco de agressividade. A taxa de recaída na doença localizada foi alta. E a sobrevida global dos pacientes de doença localizada e que utilizaram o imatinibe foi considerada satisfatória.
RESUMOIntrodução: A Hepatite C tem uma prevalência estimada de cerca de 170 milhões de pessoas mundialmente e cursa com grande morbimortalidade. O tratamento deste deste vírus tem se alterado significativamente nos últimos anos, porém, no Brasil, ainda imperam os tratamentos baseados em interferon convencional ou em interferon -peguilado associado à ribavirina. Métodos: Estudo de coorte, retrospectivo, conduzido no Hospital de Clínicas dePorto Alegre. Foram incluídos 237 pacientes com Hepatite C tratados com interferon e ribavirina ou com interferon -peguilado e ribavirina.Resultados: A taxa global de resposta virológica sustentada obtida foi de 33,33%, sendo 37,93% nos pacientes com regime baseado em interferon convencional e 32,69% nos pacientes com interferon -peguilado. A análise demonstrou uma maior taxa de resposta virológica sustentada entre os pacientes que apresentaram, à análise genética, expressão CC do polimorfismo do IL 28B. Palavras-chave: Hepatite C; interferon; resposta virológica sustentada ABSTRACTIntroduction: Hepatitis C affects approximately 170 million people worldwide and it results in great morbidity and mortality. The virus treatment has changed significantly. However, in Brazil, treatments based on conventional interferon or pegylated-interferon associated with ribavirin are still the most usual ones.
