Resumo Objetivo: Descrever o comportamento da fosfatase alcalina total (tALP) em pacientes com carcinoma de próstata metastático resistente a castração, submetidos a terapia com rádio-223 em um cenário do mundo real, e a sobrevida global (SG) desses pacientes. Materiais e Métodos: Estudo retrospectivo envolvento 97 pacientes, no período de fevereiro/2017 a setembro/2020. Os pacientes foram estratificados de acordo com a tALP basal (normal/elevada). A resposta à tALP foi definida como uma redução em relação à linha de base de ≥ 30% na semana-12. Para pacientes com tALP basal elevada, também foi avaliada a resposta ao tratamento como uma redução de ≥ 10% de tALP após o primeiro ciclo. A SG foi definida como o tempo entre o primeiro ciclo e a data do óbito. Resultados: A redução da tALP média após cada ciclo foi significativa (p < 0,05). A tALP na semana 12 estava disponível para 71 dos 97 pacientes. Desses 71 pacientes, 26 (36,6%) responderam. Dezenove (40,4%) dos 47 pacientes com tALP elevada apresentaram resposta. Foi observada uma SG mais longa nos pacientes com tALP basal normal, nos pacientes com tALP basal elevada que apresentaram resposta ao tratamento (redução de ≥ 10%) e nos pacientes que receberam 5-6 ciclos. Conclusão: A tALP pode ser usada para prever parte dos pacientes que se beneficiarão do tratamento com um maior número de ciclos e uma SG mais longa.

Abstract Objective: To describe the behavior of total alkaline phosphatase (tALP) in patients with metastatic castration-resistant prostate cancer receiving radium-223 therapy, in a real-world scenario, and to describe overall survival (OS) among such patients. Materials and Methods: This was a retrospective study involving 97 patients treated between February 2017 and September 2020. Patients were stratified by the baseline tALP (normal/elevated). A tALP response was defined as a ≥ 30% reduction from baseline at week 12. For patients with elevated baseline tALP, we also evaluated treatment response as a ≥ 10% reduction in tALP after the first cycle of treatment. We defined OS as the time from the first treatment cycle to the date of death. Results: There was a significant reduction in the median tALP after each cycle of treatment (p < 0.05 for all). Data for tALP at week 12 were available for 71 of the 97 patients. Of those 71 patients, 26 (36.6%) responded. Elevated baseline tALP was observed in 47 patients, of whom 19 (40.4%) showed a response. Longer OS was observed in the patients with normal baseline tALP, in those with elevated baseline tALP that showed a response to treatment (≥ 10% reduction), and in those who received 5-6 cycles of therapy. Conclusion: The tALP may be used to predict which patients will benefit from treatment with a greater number of cycles of radium-223 therapy and will have longer OS.

Resumo Contexto As fraturas de stents implantados na artéria femoral superficial (AFS) são uma complicação reconhecida pós-tratamento endovascular desse território arterial. Objetivos Este estudo objetivou determinar a presença de fraturas nos stents implantados na AFS e identificar fatores predisponentes para essas fraturas, juntamente com o impacto na perviedade desses dispositivos. Métodos Foram incluídos 39 pacientes (65,7±9,0 anos) previamente submetidos à angioplastia para colocação de 56 stents na AFS. Durante o seguimento, que variou de 7 a 46 meses, foram coletadas variáveis referentes às características das lesões tratadas e às características dos stents implantados. Dois examinadores analisaram radiografias digitais para verificar a presença de fraturas de stent e a perviedade dos dispositivos independentemente. Resultados Foi encontrada uma prevalência de 10,7% de fratura nos stents implantados. O implante de múltiplos stents foi identificado como fator predisponente significativo para fraturas. Foi observada uma tendência acentuada de fraturas em pacientes do sexo feminino e em lesões tratadas com stents mais longos (> 150 mm). As estenoses acima de 50% e as oclusões foram significativamente mais frequentes em stents fraturados. Conclusões Este estudo sugere que implantes de múltiplos stents ou de stents com extensão maior que 150 mm estão associados a maiores taxas de fraturas do dispositivo. No caso de fraturas de stents, as estenoses mais significativas que 50% e as oclusões foram consideravelmente mais frequentes.

Abstract Background Fractures in stents implanted in the superficial femoral artery (SFA) are recognized complications of endovascular management of this arterial territory. Objectives The objective of this study was to determine the prevalence of fractures in stents implanted in the SFA and to identify predisposing factors for these fractures together with their impact on the patency of these devices. Methods The study included 39 patients (65.7±9.0 years) who previously underwent angioplasty for delivery of 56 stents into the SFA. During follow-up, which ranged from 7 to 46 months, variables were collected on the characteristics of the lesions treated and characteristics of the stents implanted. Two examiners independently analyzed digital radiographs for the presence of stent fractures and the patency of the devices. Results We found a 10.7% prevalence of fracture of implanted stents. Implantation of multiple stents was identified as a significant predisposing factor for fractures. We observed a marked tendency for fractures in female patients and in lesions treated with longer stents (> 150 mm). Stenosis exceeding 50% and occlusions were significantly more frequent in fractured stents. Conclusions This study suggests that implants longer than 150 mm and multiple stents are associated with higher device fracture rates. In cases with stent fractures, stenoses exceeding 50% and occlusions were significantly more frequent.

RESUMO Objetivo: avaliar o impacto da quimioterapia intraperitoneal hipertérmica (HIPEC) de curta duração (i.e.: 30 minutos) na qualidade de vida (QoL) relacionada à saúde (HRQoL) no contexto de ensaio clínico terapêutico piloto; NCT02249013. Métodos: avaliou-se o desfecho secundário predeterminado de HRQoL em ensaio clínico de fase 2 de segurança e eficácia, aberto, multicêntrico, de braço único, utilizando-se o questionário European Organization for Research and Treatment of Cancer Quality of Life (EORTC QLQ-C30, versão 3.0). As pacientes foram solicitadas a responder o questionário de HRQoL antes do tratamento, após a HIPEC, e ao fim do tratamento interdisciplinar. As variações da HRQoL ao longo do tempo foram avaliadas pelas medianas dos escores de cada domínio e analisadas pelo teste de Friedman, considerando-se nível de significância estatística bicaudal de 5%. Resultados: quinze pacientes com câncer de ovário de grande volume tumoral foram recrutadas do sistema de saúde pública (i.e.: SUS) entre fevereiro de 2015 e julho 2019. Um questionário basal e pelo menos um questionário de acompanhamento foram coletados de todas as pacientes. Não se observou diferença significativa ao longo do tempo na HRQoL em nenhum dos domínios ou sintomas estudados (p> 0,05). O comprometimento transitório da HRQoL imediatamente após a HIPEC de curta duração tendeu a retornar à linha de base ao final do tratamento multimodal. Conclusões: não se observou impacto significativo da HIPEC de curta duração sobre a HRQoL no contexto deste protocolo de tratamento interdisciplinar.

ABSTRACT Introduction: to evaluate the effect of short-course (i.e.: 30 minutes) HIPEC on health-related quality of life (HRQoL) in our feasibility study; NCT02249013. Methods: a prespecified secondary end-point of our open-label, multicenter, single-arm, phase 2 trial on safety and efficacy was assessed using the European Organization for Research and Treatment of Cancer Quality of Life Questionnaire Core 30 (EORTC QLQ-C30, version 3.0). Patients were required to complete the HRQoL questionnaire at baseline, after HIPEC, and after the end of the treatment. Changes of HRQoL over time were assessed by median scores for each domain and analyzed by Friedman`s test at a significant two-sided level of 0.05. Results: fifteen patients with high tumor burden EOC were recruited from our public health system between February 2015 and July 2019. A baseline EORTC QLQ-C30 questionnaire and at least one follow-up questionnaire was received from all of the patients. No significant difference over time in the QLQC30 summary scores was observed (p>0.05). The transitory impairment on patients HRQoL immediately after the short-course HIPEC trended to return to baseline at the end of the multimodal treatment. Conclusions: we found no significant impairment of short-course HIPEC on patients HRQoL into the context of our comprehensive treatment protocol.

Abstract Objective: Endovascular techniques to treat abdominal aortic aneurysms results in lower morbidity and mortality rates. However, dilation of the common iliac arteries prevents adequate distal sealing, which compromises the procedure success. The aim of this study is report the long-term outcomes of patients with abdominal aortic aneurysms associated with aneurysm of the common iliac artery following endovascular repair using a bifurcated bell-bottom stent graft. Methods: This is a retrospective study that evaluated patients treated with bifurcated bell-bottom extension stent grafts to repair an infrarenal abdominal aortic aneurysm and who had at least one common iliac artery with dilatation > 1.5 cm for at least 12 months after the endovascular intervention. Results: Thirty-eight patients with a mean age of 70.4±8.2 years were included. Stent graft placement was followed by dilation of the common iliac artery aneurysms in 35.3% of cases; endoleak and reoperation rates were 17.6% and 15.7%, respectively. Younger patients showed a higher rate of artery diameter increase following the procedure. The average arterial dilation was 16% in the first year, 29% in the second year, 57% in the third year and 95% from the fourth year until the end of follow-up. Conclusion: Repair of infrarenal abdominal aortic aneurysms with bifurcated bell-bottom type stents when there is common iliac artery dilation is a good therapeutic option to preserve hypogastric flow. The rate of endoleak was 17.6%, and 15.7% of cases required reoperation. Younger patients are more likely to experience dilation of the common iliac artery after the procedure.

O objetivo foi descrever um surto de infecções da corrente sanguínea por complexo B. cepacia (Bcc) nos ambulatórios de hematologia e transplante de medula óssea. Métodos: Em 15/02/2008, um surto de Bcc foi suspeitado. 24 casos foram identificados. Os dados demográficos e clínicos foram avaliados. Mãos de profissionais da saúde e ambiente foram cultivadas. Espécies foram determinadas e tipadas. Reforço da higiene das mãos, cuidados com cateteres, terapia de infusão e manutenção da câmara de fluxo laminar foram realizadas. 16 profissionais de saúde (PS) diferentes manipularam os cateteres. Heparina multidoses e soro eram preparadas em um balcão comum a ambas as unidades. Resultados: 14 pacientes tiveram B. multivorans(um paciente teve também B. cenopacia), 6 Bcc não-multivorans e um teve um agente não pertencente a Bcc. Clone A de B. multivorans ocorreu em 12 pacientes (da Hematologia), em 10 o cateter havia sido utilizado nos dias 11 ou 12 de fevereiro. Culturas ambientais e de PS foram negativos. Todos os pacientes foram tratados com meropenem e selo de ceftazidima. Oito pacientes (30%) foram hospitalizados. Não ocorreram mortes. Após as medidas de controle, nenhum novo caso ocorreu. Conclusões: Este surto policlonal pode ser explicado por uma fonte comum contendo várias espécies de Bcc, talvez a câmara de fluxo laminar comum a ambas as unidades. Pode ter havido contaminação por B. multivorans (clone A) de frascos multi-dose.

Aim: The objective was to describe an outbreak of bloodstream infections by Burkholderia cepacia complex (Bcc) in bone marrow transplant and hematology outpatients.Methods: On February 15, 2008 a Bcc outbreak was suspected. 24 cases were identified. Demographic and clinical data were evaluated. Environment and healthcare workers' (HCW) hands were cultured. Species were determined and typed. Reinforcement of hand hygiene, central venous catheter (CVC) care, infusion therapy, and maintenance of laminar flow cabinet were undertaken. 16 different HCWs had cared for the CVCs. Multi-dose heparin and saline were prepared on counter common to both units.Findings: 14 patients had B. multivorans(one patient had also B. cenopacia), six non-multivorans Bcc and one did not belong to Bcc. Clone A B. multivorans occurred in 12 patients (from Hematology); in 10 their CVC had been used on February 11/12. Environmental and HCW cultures were negative. All patients were treated with meropenem, and ceftazidime lock-therapy. Eight patients (30%) were hospitalized. No deaths occurred. After control measures (multidose vial for single patient; CVC lock with ceftazidime; cleaning of laminar flow cabinet; hand hygiene improvement; use of cabinet to store prepared medication), no new cases occurred.Conclusions: This polyclonal outbreak may be explained by a common source containing multiple species of Bcc, maybe the laminar flow cabinet common to both units. There may have been contamination by B. multivorans (clone A) of multi-dose vials.

INTRODUÇÃO: A cirurgia por técnicas não derivativas é o tratamento de escolha para o controle da hemorragia digestiva alta secundária à hipertensão portal esquistossomótica. Contudo, a recidiva hemorrágica em decorrência das varizes gastroesofágicas é um evento frequente. O programa de erradicação endoscópica das varizes gastroesofágicas tem o objetivo de prevenir e/ou tratar a recidiva hemorrágica, porém nem todos os doentes respondem ao tratamento. OBJETIVO: Avaliar o sucesso do tratamento de embolização da veia gástrica esquerda no controle da recidiva hemorrágica por varizes gastroesofágicas nos doentes esquistossomóticos submetidos previamente a cirurgia não derivativa. MÉTODOS: Foram estudadas, por meio de dados colhidos nos prontuários médicos e dos protocolos de seguimento ambulatorial, a incidência da recidiva hemorrágica e a diminuição quantitativa e qualitativa das varizes gastroesofágicas em detrimento das varizes gastroesofágicas dos doentes encaminhados para embolização transhepática da veia gástrica esquerda no período de dezembro de 1999 até janeiro de 2009. RESULTADOS: Sete doentes com média etária de 39,3 anos foram encaminhados para embolização percutânea transhepática da veia gástrica esquerda. O tempo médio decorrido entre a DAPE e a abordagem percutânea foi de 8,4 ± 7,3 anos e o número de episódios de hemorragia digestiva variou de um a sete neste período. Nenhum episódio de ressangramento foi verificado na população do estudo durante o período de acompanhamento, que variou de 6 meses a 7 anos. Após estudo endoscópico pós-embolização, todos os doentes apresentaram diminuição das varizes gastroesofágicas em comparação à endoscopia pré-embolização. CONCLUSÃO: A embolização percutânea transepática da veia gástrica esquerda nos doentes esquistossomóticos, previamente operados, determinou a redução das varizes gastroesofágicas e foi eficiente no controle do ressangramento para a população estudada.

CONTEXT: Non-derivative surgical techniques are the treatment of choice for the control of upper digestive tract hemorrhages after schistosomotic portal hypertension. However, recurrent hemorrhaging due to gastroesophagic varices is frequent. OBJECTIVE: To evaluate the outcome of treatment based on embolization of the left gastric vein to control the reoccurrence of hemorrhages caused by gastroesophagic varices in patients with schistosomiasis previously submitted to non-derivative surgery. METHODS: Rates of reoccurrence of hemorrhages and the qualitative and quantitative reduction of gastroesophagic varices in patients undergoing transhepatic embolization of the left gastric vein between December 1999 and January 2009 were studied based on medical charts and follow-up reports. RESULTS: Seven patients with a mean age of 39.3 years underwent percutaneous transhepatic embolization of the left gastric vein. The mean time between azigoportal disconnections employed in combination with splenectomy and the percutaneous approach was 8.4 ± 7.3 years, and the number of episodes of digestive hemorrhaging ranged from 1 to 7 years. No episodes of reoccurrence of hemorrhaging were found during a follow-up period which ranged from 6 months to 7 years. Endoscopic postembolization studies revealed reductions in gastroesophagic varices in all patients compared to preembolization endoscopy. CONCLUSIONS: Percutaneous transhepatic embolization of the left gastric vein in patients with schistosomiasis previously submitted to surgery resulted in a decrease in gastroesophagic varices and was shown to be effective in controlling hemorrhage reoccurrence.

Abstract: En | Text: En | PDF: En

OBJECTIVE: Prevention is the best treatment for cerebrovascular disease, which is why early diagnosis and the immediate treatment of carotid stenosis contribute significantly to reducing the incidence of stroke. Given its silent nature, 80% of stroke cases occur in asymptomatic individuals, emphasizing the importance of screening individuals with carotid stenosis and identifying high-risk groups for the disease. The aim of this study was to determine the prevalence and the most frequent risk factors for carotid stenosis. METHODS: A transversal study was conducted in the form of a stroke prevention campaign held on three nonconsecutive Saturdays. During the sessions, carotid stenosis diagnostic procedures were performed for 500 individuals aged 60 years or older who had systemic arterial hypertension and/or diabetes mellitus and/or coronary heart disease and/or a family history of stroke. RESULTS: The prevalence of carotid stenosis in the population studied was 7.4%, and the most frequent risk factors identified were mean age of 70 years, carotid bruit, peripheral obstructive arterial disease, coronary insufficiency and smoking. Independent predictive factors of carotid stenosis include the presence of carotid bruit or peripheral obstructive heart disease and/or coronary insufficiency. CONCLUSIONS: The population with peripheral obstructive heart disease and carotid bruit should undergo routine screening for carotid stenosis.

Abstract: Pt En | Text: Pt En | PDF: Pt | PDF: En

A correção endovascular da dissecção de aorta tipo B tem se mostrado como uma nova alternativa para reduzir o trauma cirúrgico. No entanto, as complicações de médio e longo prazo, tais como a fístula aortoesofágica, são ainda pouco conhecidas e pouco relatadas. O objetivo deste trabalho é descrever três casos de fístula aortoesofágica após o tratamento endovascular de 23 casos de dissecção de aorta descendente conduzidos pela equipe de Cirurgia Vascular da Santa Casa de São Paulo em um estudo retrospectivo. Esses pacientes apresentavam características em comum, como dissecção crônica, pós-operatório imediato sem intercorrências, necessidade de reintervenções, oclusão de troncos arteriais como a artéria subclávia, mesentérica, tronco celíaco, e, ainda, uma rápida evolução para o óbito após os primeiros sinais de fístula. Portanto, embora raramente descrita na literatura, a ocorrência de fístula aortoesofágica é uma complicação de causa até o momento indefinida do tratamento endovascular da dissecção de aorta descendente que merece atenção, dada sua recorrência e evolução fatal.

Endoluminal stent-graft for type B aortic dissection is a new alternative to reduce surgical trauma. However, medium- and long-term complications are still little known and poorly reported, such as the aortic-esophageal fistula. The objective of this study is to describe three cases of aortic-esophageal fistula after the endovascular treatment of 23 cases of descending aortic dissection conducted by the vascular surgery team of Santa Casa de São Paulo in a retrospective study. These patients presented some common characteristics: chronic dissection, successful early outcome, need of reinterventions, occlusion of arterial trunks such as subclavian artery, mesenteric artery, celiac trunk, and finally, a fast fatal course after the first fistula-related symptoms. Therefore, despite rarely described in the literature, aortic-esophageal fistula is a complication of the endovascular treatment of descending aortic dissection which demands attention due to its unpredictability, recurrence, and fatal outcome.

Diariamente novos artigos científicos sobre tuberculose (TB) são publicados em todo mundo. No entanto, é difícil para o profissional sobrecarregado na rotina de trabalho acompanhar a literatura e discernir o que pode e deve ser aplicado na prática diária juntos aos pacientes com TB. A proposta das "III Diretrizes para TB da Sociedade Brasileira de Pneumologia e Tisiologia (SBPT)" é revisar de forma crítica o que existe de mais recente na literatura científica nacional e internacional sobre TB e apresentar aos profissionais da área de saúde as ferramentas mais atuais e úteis para o enfrentamento da TB no nosso país. As atuais "III Diretrizes para TB da SBPT" foram desenvolvidas pela Comissão de TB da SBPT e pelo Grupo de Trabalho para TB a partir do texto das "II Diretrizes para TB da SBPT" (2004). As bases de dados consultadas foram LILACS (SciELO) e PubMed (Medline). Os artigos citados foram avaliados para determinação do nível de evidência científica, e 24 recomendações sobre TB foram avaliadas, discutidas por todo grupo e colocadas em destaque. A primeira versão das "III Diretrizes para TB da SBPT" foi colocada no website da SBPT para consulta pública durante três semanas, e as sugestões, críticas e o nível de evidência da referência científica que as embasavam foram avaliados e discutidos antes de serem incorporadas ou não ao texto final.

New scientific articles about tuberculosis (TB) are published daily worldwide. However, it is difficult for health care workers, overloaded with work, to stay abreast of the latest research findings and to discern which information can and should be used in their daily practice on assisting TB patients. The purpose of the III Brazilian Thoracic Association (BTA) Guidelines on TB is to critically review the most recent national and international scientific information on TB, presenting an updated text with the most current and useful tools against TB to health care workers in our country. The III BTA Guidelines on TB have been developed by the BTA Committee on TB and the TB Work Group, based on the text of the II BTA Guidelines on TB (2004). We reviewed the following databases: LILACS (SciELO) and PubMed (Medline). The level of evidence of the cited articles was determined, and 24 recommendations on TB have been evaluated, discussed by all of the members of the BTA Committee on TB and of the TB Work Group, and highlighted. The first version of the present Guidelines was posted on the BTA website and was available for public consultation for three weeks. Comments and critiques were evaluated. The level of scientific evidence of each reference was evaluated before its acceptance for use in the final text.

Abstract: En | Text: En | PDF: En

This study investigated the risk factors associated with recent and chronic HIV infections among individual attending a voluntary counseling and testing (VCT) site in Rio de Janeiro, Brazil. In a cross-sectional study, recent HIV infections were detected by the sensitive/less-sensitive test, using Serologic Testing Algorithm for Recent HIV Seroconversion (STARHS) strategy, and compared to chronic HIV infection and HIV negative individuals. Seroincidence was estimated and risk factors associated with recent and chronic infections were assessed using multinomial logistic regression. Among the 7,379 individuals tested between June 2006 and April 2007, the overall prevalence and incidence of HIV infection were 7.5%; and 1.39/100 PY, respectively. In multivariate analysis, having a HIV positive steady partner was a risk factor for recent and for chronic HIV infection for MSM, heterosexual male and women. No differences in risk factors for recent and chronic infections were found between MSM and heterosexual males. Among women, chronic infected individuals were more likely than HIV negatives to be older. Recently HIV infected women were more likely than HIV negatives to be less educated; and more likely than HIV negatives and chronically infected to report having more partners. Routinely used risk-based assessment in testing centers in Brazil lack sensitivity to distinguish between recent and chronic infections, particularly among MSM and heterosexual males. Steady relationships and serosorting may be playing a key role in maintaining the HIV epidemics in Brazil.

O trabalho investiga o contexto da primeira injeção de drogas e sua associação com práticas atuais de injeção e infecção pelo HCV (vírus da hepatite C). Usuários de drogas injetáveis (UDI) (N = 606) foram recrutados em cenas de uso (ruas, bares) do Rio de Janeiro, Brasil, entrevistados e testados (anti-HCV). A freqüência de compartilhamento de agulhas e seringas foi superior na primeira injeção (51,3%), se comparada à atualmente referida (36,8%). Usuários que iniciaram o uso injetável compartilhando agulhas/seringas relataram uma freqüência significativamente maior de compartilhamento direto/indireto de agulhas/seringas nos últimos seis meses. A infecção pelo HCV foi quatro vezes mais prevalente entre UDI jovens (< 30 anos) que compartilharam agulhas e seringas na primeira injeção. A prevalência de anti-HCV foi 11% entre UDI ativos (n = 272) e se mostrou independentemente associada à história de prisão e à duração do uso de drogas injetáveis. A prevenção da disseminação do HCV nesta população requer a adoção de medidas de redução de riscos e danos associados à injeção de drogas já desde a primeira injeção ou, antes, um desestímulo à transição do uso não injetável para injetável.

The context of first drug injection and its association with ongoing injecting practices and HCV (hepatitis C virus) infection were investigated. Injection drug users (IDUs) (N = 606) were recruited in "drug scenes" (public places, bars) in Rio de Janeiro, Brazil, interviewed, and tested for HCV. Sharing of needles/syringes was more prevalent at the first injection (51.3%) than at the baseline interview (36.8%). Those who shared syringes/needles at first injection were more likely to be currently engaged in direct/indirect sharing practices. Among young injectors (< 30 years), those reporting sharing of needles/ syringes at the first injection were about four times more likely to have been infected by HCV. Hepatitis C virus prevalence among active IDUs (n = 272) was 11%. Prison history and longer duration of drug injection were identified as independent predictors of HCV infection. To effectively curb HCV transmission among IDUs and minimize harms associated with risk behaviors, preventive strategies should target individuals initiating drug injection beginning with their very first injection and discourage the transition from non-injecting use to the self-injection of illicit drugs.

Abstract: Pt En | Text: Pt En | PDF: Pt | PDF: En

Ações preventivas ainda são essenciais ao controle da epidemia de AIDS; contudo, programas de prevenção eficazes dependem da distribuição correta e eficiente dos recursos de saúde. Assim, informações acerca de onde, quando, com que intensidade e como se difundirá a epidemia são valiosos. Este estudo visou obter melhor compreensão do processo de difusão espacial dos casos de AIDS em quatro Estados brasileiros. Tais padrões foram avaliados qualitativamente - estudo de mapas seqüenciais - e quantitativamente - análise de correlogramas espaciais - ao longo de dez anos, agrupados em três períodos: 1987-1989, 1990-1992 e 1993-1996. O processo de difusão foi estudado para o total de casos de AIDS e para os do sexo feminino e masculino. De modo geral, houve difusão significativa dos casos de AIDS nos períodos, mas o processo exibiu características específicas a cada Estado. As informações obtidas - em especial, os resultados da análise de correlogramas - permitem entender melhor os padrões de difusão espacial da epidemia em diferentes partes do País e podem ser empregadas para fixar parâmetros a outros modelos epidemiológicos da AIDS.

Despite new improvements in AIDS treatment, preventive measures are still essential to control the epidemic. Effective programs almost always depend on correct and efficient allocation of scarce health resources. Detailed information on the epidemic, such as where, when, and how the epidemic will spread are of great value. This study was conducted to obtain a better understanding of the dissemination of AIDS cases in four important Brazilian States. Spatial diffusion patterns were evaluated qualitatively by studying sequential maps and quantitatively by analyzing spatial correlograms. Ten years were analyzed, grouped in three periods (1987-1989, 1990-1992, and 1993-1996). The diffusion process was studied for both total AIDS cases and male and female cases. Diffusion of AIDS cases presented specific characteristics for each of the four States. Information derived from the study, especially the results of the correlogram analysis, improve our understanding of the epidemic's spatial diffusion in different parts of the country and can also be used to determine parameters for other AIDS epidemiological models.

CONTEXTO: Oncocitomas são tumores geralmente pequenos e apresentam crescimento lento. A identificação do tumor usualmente ocorre incidentemente. Sua incidência é maior entre os homens. Oncocitomas originários das glândulas mucosas dos brônquios são muito raros. RELATO DE CASO: Um paciente de 35 anos do sexo masculino com oncocitoma brônquico. O tumor foi observado à broncoscopia, realizada para investigação de atelectasia do lobo superior esquerdo. O exame histológico com microscopia ótica mostrou neoplasia madura formada por células ovóides com citoplasma eosinofílico fino e granular, com núcleo pequeno, assemelhando-se a oncocitos. A microscopia eletrônica mostrou hiperplasia mitocondrial. O seguimento três anos após a toracotomia com lobectomia e remoção do tumor foi livre de complicações ou recidiva.

CONTEXT: Oncocytomas are generally small and present slow growth. Finding of the tumor usually occurs incidentally. Their incidence is higher among male patients. Oncocytomas in mucous bronchial glands are extremely rare. CASE REPORT: A 35-year-old male who presented bronchial oncocytoma. The tumor was found after bronchoscopy that investigated an atelectasis of the upper left lobe. Histological examination with optical microscopy revealed a mature neoplasm formed by ovoid cells with thin, granular, eosinophilic cytoplasm and small nuclei similar to oncocytes. Electron microscopy showed mitochondrial hyperplasia. A three-year follow-up after thoracotomy followed by lobectomy and removal of the bronchial tumor was uneventful.
