HIV infection and AIDS in a small municipality in Southeast Brazil

OBJECTIVE: Studies on the aspects of HIV infection in small Brazilian municipalities are invaluable to appropriately design control strategies, better allocate resources, and improve health care services. The objective of the study was to assess the clinical and epidemiological aspects of HIV infection in a small municipality. METHODS: A descriptive study was carried out in Miracema, a small municipality in the northwestern area of the state of Rio de Janeiro, Brazil, between July 1999 and December 2003. All HIV-infected adult patients followed up at the local HIV/AIDS Program were included. Clinical and epidemiologic characteristics were prospectively assessed through standardized questionnaires. RESULTS: A total of 65 adult patients who attended the local HIV/AIDS Program were analyzed. Most (34) were women (male to female ratio: 0.9). An absolute predominance of patients who were born in Miracema or neighboring municipalities (94%), lived in Miracema (90.7%), were single (70.8%), attributed the acquisition of HIV infection to unprotected heterosexual intercourse (72.3%) and had a past history of snorting cocaine (27.7) was found Central nervous system disorders (including five cases of cryptococcal meningitis) and acute pulmonary pneumocystosis-like respiratory failure were major causes of morbidity. Most patients (56.9%) were at presented in advanced stages of HIV infection. CONCLUSIONS: The predominance of patients on advanced stages of HIV infection suggest the existence of a large pool of undiagnosed cases in the community. A major feature of the cohort was an inverted male to female ratio. Further investigations over a broader geographic area are urgently needed for better understanding the clinical and epidemiological characteristics of HIV infection in small Brazilian municipalities and rural areas.

Trends in public health policies addressing violence against women

OBJECTIVE To analyze the content of policies and action plans within the public healthcare system that addresses the issue of violence against women.METHODS A descriptive and comparative study was conducted on the health policies and plans in Catalonia and Costa Rica from 2005 to 2011. It uses a qualitative methodology with documentary analysis. It is classified by topics that describe and interpret the contents. We considered dimensions, such as principles, strategies, concepts concerning violence against women, health trends, and evaluations.RESULTS Thirteen public policy documents were analyzed. In both countries’ contexts, we have provided an overview of violence against women as a problem whose roots are in gender inequality. The strategies of gender policies that address violence against women are cultural exchange and institutional action within the public healthcare system. The actions of the healthcare sector are expanded into specific plans. The priorities and specificity of actions in healthcare plans were the distinguishing features between the two countries.CONCLUSIONS The common features of the healthcare plans in both the counties include violence against women, use of protocols, detection tasks, care and recovery for women, and professional self-care. Catalonia does not consider healthcare actions with aggressors. Costa Rica has a lower specificity in conceptualization and protocol patterns, as well as a lack of updates concerning health standards in Catalonia.

Trends of T. cruzi infection based on data from blood bank screening

Between October 1988 and April 1989 a cross-sectional survey was carried out in six out of eight blood banks of Goiânia, Central Brazil. Subjects attending for first-time blood donation in the mornings of the study period (n = 1358) were interviewed and screened for T. cruzi infection as a part of a major study among blood donors. Tests to anti-T. cruzi antibodies were performed, simultaneously, by indirect hem agglutination test (IHA) and complement fixation test (CFT). A subject was considered seropositive when any one of the two tests showed a positive result. Information on age, sex, place of birth, migration and socio-economic level was recorded. Results from this survey were compared with seroprevalence rates obtained in previous studies in an attempt to analyse trend of T. cruzi infection in an endemic urban area. The overall seroprevalence of T. cruzi infection among first-time donors was found to be 3.5% (95% confidence interval 2.5%-4.5% ). The seroprevalence rate increased with age up to 45 years and then decreased. Migrants from rural areas had higher seroprevalence rates than subjects from urban counties (1.8%-16.2% vs. 0%-3.6%). A four fold decrease in prevalence rates was observed when these rates were compared with those of fifteen years ago. Two possible hypotheses to explain this difference were suggested: 1. a cohort effect related with the decrease of transmission in rural areas and/or 2. a differential proportion of people of rural origin among blood donors between the two periods. The potential usefulness of blood banks as a source of epidemiological information to monitor trends of T. cruzi infection in an urban adult population was stressed.

Relationship between the prevalence of antibodies to hepatitis B core antigen and arbovirus in fishermen from the Ribeira Valley, Brazil

Sera from 299 fishermen 16 to 80 years old, residents in Cananeia and Iguape counties, southern cost of São Paulo State, Brazil, were studied in order to identify a possible association between the prevalence of specific antibodies to the hepatitis B virus (HBV) and exposure to haematophagus mosquitoes evaluated by the prevalence of arbovirus antibodies. This professional group presented the highest prevalence of arbovirus antibodies (54.1%) in past investigations carried out in this heavily forested region. Detection of antibody to hepatitis B core antigen (anti-HBc) in the sera was done by enzyme immunoassay (Roche). Prevalence of anti-HBc antibodies in this group was 31.4% (94/299) which is very high compared with 7.2% to 15.0% for different groups of healthy adults in State of São Paulo. No significant difference is observed between the prevalences of HBV antibodies in Iguape and Cananeia. Prevalence of anti-HBc and anti-arbovirus antibodies increases with age. There is a concordance in the distribution according to age groups of the frequency of anti-HBc and anti-arbovirus positive sera. Ag HBs was detected in 4% of the studied sera. These results support the hypothesis that the transmission of the hepatitis B virus and the arboviruses may be due to the same factor, one of the possibilities would be by anthropophilic mosquitoes.

Dengue epidemic in the state of Rio de Janeiro, Brazil: virological and epidemiological aspects

Laboratorial studies were carried out on 3178 patients with signs and symptoms suggestive of dengue infection from April 1986 to December 1987 in the State of Rio de Janeiro, Brazil. The epidemic had two peaks following the first virus isolation and affected the inhabitants of 17 counties. Both sex and all age groups were affected. Dengue virus type 1 was isolated from 1039 sera and the number of confirmed cases was increased to 1874 (59%) by MAC-ELISA. Isolation rate confirmed cases reached 80% in the specimens obtained until the 4th day after the onset of disease and viraemia ranged from 10 3.0 to 10(8.5) TCID50/ml.

Surveillance of arbovirus infections in the atlantic forest region, State of São Paulo, Brazil: I. detection of hemagglutination-inhibition antibodies in wild birds between 1978 and 1990

We report data related to arbovirus antibodies detected in wild birds periodically captured from January 1978 to December 1990 in the counties of Salesópolis (Casa Grande Station), Itapetininga and Ribeira Valley, considering the different capture environments. Plasmas were examined using hemagglutination-inhibition (HI) tests. Only monotypic reactions were considered, except for two heterotypic reactions in which a significant difference in titer was observed for a determined virus of the same antigenic group. Among a total of 39,911 birds, 269 birds (0.7%) belonging to 66 species and 22 families were found to have a monotypic reaction for Eastern equine encephalitis (EEE), Venezuelan equine encephalitis (VEE), Western equine encephalitis (WEE), Ilheus (ILH), Rocio (ROC), St. Louis encephalitis (SLE), SP An 71686, or Caraparu (CAR) viruses. Analysis of the data provided information of epidemiologic interest with respect to these agents. Birds with positive serology were distributed among different habitats, with a predominance of unforested habitats. The greatest diversity of positive reactions was observed among species which concentrate in culture fields.

Dengue type 2 outbreak in the south of the State of Bahia, Brazil: laboratorial and epidemiological studies

During March 1994 cases of a exanthematic acute disease were reported in the municipalities of Itagemirim, Eunápolis and Belmonte, state of Bahia. Dengue fever was confirmed by serology (MAC-ELISA) and by dengue virus type 2 isolation, genotype Jamaica. Signs and symptoms of classic dengue fever were observed with a high percentual of rash (73.8%) and pruritus (50.5%). Major haemorrhagic manifestations were unfrequent and only bleeding gum was reported. Dengue virus activity spreaded rapidly to important tourism counties like Porto Seguro, Ilhéus, Santa Cruz de Cabrália, Prado, Alcobaça and others, representing a risk for the spreading of dengue virus into the country and abroad.

Paracoccidioidomycosis in children in the state of Rio de Janeiro (Brazil): Geographic distribution and the study of a "reservarea"

Thirty six cases of acute disseminated paracoccidioidomycosis in 3 to 12 year-old children, natives of the state of Rio de Janeiro, were seen in the period 1981-1996. All patients were residents in the rural region of 15 counties, scattered on the Southwestern part of this state. The rural region of two neighboring counties, where 16 cases (44.4%) occurred, was visited. It exhibited the environmental conditions that are considered favorable to the survival of P. brasiliensis. The most important of these conditions, abundant watercourses and autochthonous forest, are distributed on well defined and limited areas, in which the dwellings are also localized. Probably, a careful epidemiological study of forthcoming cases of the disease in children may facilitate the search for the micro-niche of the fungus.

Molecular characterization of two rocio flavivirus strains isolated during the encephalitis epidemic in são paulo state, brazil and the development of a one-step rt-pcr assay for diagnosis

Rocio virus (ROCV) was responsible for an explosive encephalitis epidemic in the 1970s affecting about 1,000 residents of 20 coastland counties in São Paulo State, Brazil. ROCV was first isolated in 1975 from the cerebellum of a fatal human case of encephalitis. Clinical manifestations of the illness are similar to those described for St. Louis encephalitis. ROCV shows intense antigenic cross-reactivity with Japanese encephalitis complex (JEC) viruses, particularly with Ilheus (ILHV), St. Louis encephalitis, Murray Valley and West Nile viruses. In this study, we report a specific RT-PCR assay for ROCV diagnosis and the molecular characterization of the SPAn37630 and SPH37623 strains. Partial nucleotide sequences of NS5 and E genes determined from both strains were used in phylogenetic analysis. The results indicated that these strains are closely related to JEC viruses, but forming a distinct subclade together with ILHV, in accordance with results recently reported by Medeiros et al. (2007).

Yellow fever epizootics in non-human primates, São Paulo state, Brazil, 2008-2009

Since 2000, the expansion of Sylvatic Yellow Fever (YF) has been observed in the southeast of Brazil, being detected in areas considered silent for decades. Epizootics in non-human primates (NHPs) are considered sentinel events for the detection of human cases. It is important to report epizootic events that could have impact on the conservation status of susceptible species. We describe the epizootics in NHPs, notified in state of São Paulo, Brazil, between September 2008 to August 2009. Ninety-one epizootic events, involving 147 animals, were reported in 36 counties. Samples were obtained from 65 animals (44.2%). Most of the epizootics (46.6%) were reported between March and April, the same period during which human cases of YF occurred in the state. Biological samples were collected from animals found dead and were sent to Instituto Adolfo Lutz, in São Paulo. Two samples, collected in two counties without an indication for YF vaccination, were positive for the virus. Another 48 animals were associated with YF by clinical-epidemiological linkage with laboratory confirmed cases. Because the disease in human and NHPs occurred in the same period, the detection of the virus in NHPs did not work as sentinel, but aided in the delineation of new areas of risk.

The association of Schistosoma mansoni infection with hepatocellular carcinoma

The association of Schistosoma mansoni infection with hepatocellular carcinoma (HCC) was studied in Espirito Santo State, Brazil. Schistosoma infection was diagnosed by stool examinations or by histological finding at autopsy. HCC was diagnosed by biopsy, laparoscopy and biopsy or at autopsy. Among 45 cases of HCC six had Schistosoma mansoni infection (13.04%). The occurrence of Schistosoma infection among HCC HBs Ag positive or negative was similar (13.3 3% and 13.63% respectively). The chi squared comparison showed no significant differences between the frequency of schistosomiasis in patients with HCC and the frequency of Schistosoma infection among people living in the Espirito Santo State (5.9% among children of elementary school from all the counties of the State and 6.7% in people that attended medical care in Vitoria, the capital of the State). Therefore, the authors believe that the association of schistosomiasis mansoni with HCC may be casual, specially in areas where the Schistosoma mansoni infection is frequent.

O acesso ao tratamento em saúde Mental na microregião de Itajubá/MG-Brasil

RESUMO: A integração da saúde mental à atenção básica é a recomendação feita para facilitar o acesso ao tratamento. A pesquisa teve por objetivo mapear e analisar os facilitadores e as barreiras ao acesso ao tratamento em saúde mental da Microrregião de Itajubá, estado de Minas Gerais, Brasil, composta por 15 municípios. A metodologia pautou-se na triangulação dos métodos, combinando a abordagem quantitativa e qualitativa de pesquisa. Para tal foi feito o mapeamento da capacidade instalada dos recursos existentes e identificação das principais lacunas com base nos parâmetros da saúde pública, a partir de roteiros de entrevistas e grupos focais com os principais atores sociais implicados. Constatou-se que o maior facilitador ao acesso ao tratamento tem sido a atuação das equipes de PSF (Programa Saúde da Família), que atuam diretamente nas comunidades. Outros facilitadores foram: a atuação dos CRAS (Centro de Referência de Assistência Social); a existência de um CAPS (Centro de Atenção Psicossocial), embora não credenciado ao SUS (Sistema Único de Saúde); Colegiados de Saúde Mental que promovem discussões, informação, educação, e pressionam os municípios para a implantação de serviços de saúde mental. A falta de “vontade política”, isto é, uma intervenção mais clara da gestão pública da saúde, com estabelecimento de prioridades para prover a ampliação do acesso, foi identificada como a maior barreira a ser enfrentada na microrregião, especialmente por falta de organização e planejamento das ações em saúde mental. Serviços que trabalham de forma isolada, sem a construção de uma rede; pouca participação política dos usuários dos serviços de saúde mental; e falta de recursos humanos, e profissionais pouco preparados para a função compõem as outras barreiras de acesso. Vê-se que diante dos facilitadores e barreiras expostos é preciso que os municípios realizem um levantamento sistemático, a fim de criar um plano de ação em saúde mental para compartilhar informações, recursos, serviços, disponibilidade, disposição e ações em rede.-------------- ABSTRACT: Integrating mental health care in primary-care services is recommended in order to improve access to treatment. Access to mental health treatment has been a worldwide debated theme. In Brazil, with the Psychiatric Reform, there has been a change of paradigm in the way of treating persons with mental disorders. Various health devices were created, building a net of treatment and care that replaces the asylum system and where human rights are respected and defended and the offered treatment is the closest possible to their social space. The research aims to map and analyse the barriers and the facilitators to mental health treatment in the micro-region of Itajubá, state of Minas Gerais/Brazil, made up of 15 counties. The methodology was based on the triangulation of methods, combining quantitative and qualitative research. For that, a mapping of the installed capacity of the existent resource was carried out; identification of the main voids based on the parameters of public health through scripts of interviews and focus groups with the social actors involved. It was found that the main facilitator to treatment has been the performance of PSF, who act directly in the communities. Other facilitators also stand out: the work of CRAS; the existence of CAPS, although not accredited to SUS; Mental Health Collegiate, promoting discussions, information, education, and forcing pressure on the counties for the implantation of mental health services. The lack of political will was identified as the major barrier to be faced in the micro-region, especially due to lack of organization and planning in the actions towards mental health. The services working isolatedly, without a communication net, and the lack of human resources as well as poorly prepared professional, are the main difficulties faced by access to mental health treatment. Becomes clear that the counties need to undertake a systematic survey towards creating a plan of action in mental health, in order to share information, resources, services, availability, disposition and networking.

Piranha attacks in dammed streams used for human recreation in the State of São Paulo, Brazil

In recent years, attacks by piranhas have become a common problem in dammed portions of rivers and streams in the State of Sao Paulo, Southeastern Brazil. In two outbreaks recorded in two neighboring counties in the Northwest region of the state, 74 bathers were bitten. Only one bite per person was recorded during a short period of the year. The bites were related to parental care and/or defense of spawning territory, which confirms previous studies and demystify the attacks by these legendary fish, as they are perceived by most people. Placement of fine mesh nets and removal of aquatic vegetation stopped the attacks.

Adesão terapêutica e hipertensão arterial : o uso de fontes administrativas de dados de prescrição e levantamento de medicação na estimação da adesão à terapêutica com antagonistas dos recetores da angiotensina

RESUMO - Objetivos: São objetivos do presente estudo caraterizar a adesão terapêutica, primária e secundária, na Região de Saúde do Alentejo em utentes que seguiram tratamento para Hipertensão Arterial com Antagonistas dos Receptores da Angiotensina e constatar se a adopção de diferentes medidas produz diferentes resultados de adesão terapêutica. Metodologia: Este estudo é uma análise retrospetiva da prescrição e levantamento de ARA nos anos de 2010 e 2011 na Região de Saúde do Alentejo. Foram considerados 22.450 utentes e cinco diferentes medidas de adesão terapêutica: Rácio de Adesão Primária, Medication Possession Ratio, Compliance Rate, Refill Compliance Rate, Continuous Measure of Medication Gaps. Resultados: Constatou-se que a adesão terapêutica primária para os 22.450 utentes considerados na amostra foi de 0,612 (DP 0,325), a adesão terapêutica medida pelo indicador MPR foi de 0,557 (DP 0,380), pelo indicador CR foi de 0,697 (DP 0,517), pelo indicador RCR foi de 0,695 (DP 0,518) e pelo indicador CMG foi de 0,648 (DP 0,351). Independentemente do indicador considerado, a adesão terapêutica foi mais elevada no sexo feminino do que no sexo masculino, os utentes do sexo feminino apresentaram níveis de sobre-aquisição de medicação mais elevados e a prevalência de utentes que no período não chegaram a levantar nenhuma embalagem de medicação, não obstante a necessidade clínica ter sido identificada em pelo menos 2 momentos no período, foi mais elevada no sexo masculino. As faixas etárias acima dos 70 anos apresentaram níveis médios de adesão terapêutica significativamente superiores aos verificados nas faixas etárias que compreendem os utentes em idade ativa. Constatou-se que os concelhos que apresentaram resultados de adesão terapêutica inferiores à média amostral por um determinado indicador, em regra, viram confirmada essa tendência pelos restantes indicadores. Não obstante, verificou-se que os rankings de desempenho obtidos pelos cinco indicadores apresentaram concordância estatística fraca. Conclusões: Concluiu-se que, não obstante a existência de um conjunto de limitações e condicionalismos metodológicos, os dados atualmente recolhidos ao nível da prescrição e conferência de receituário permitem a mensuração dos comportamentos de adesão terapêutica. A inexistência de consenso científico terminológico tem conduzido à proliferação de indicadores com o fito de medir a adesão terapêutica que, sendo conceptualmente distintos na sua construção, conduzem a diferentes resultados de adesão terapêutica. Os resultados obtidos pelo presente estudo permitiram confirmar este aspecto pelo que não se recomenda a utilização de apenas um indicador para análise dos comportamentos de adesão terapêutica dos utentes.

Leprosy and pregnancy in the State of Para: an epidemiological perspective

Introduction A few older publications describe leprosy associated with pregnancy, a situation that has been linked to leprosy exacerbation. This study aimed to describe the detection rate of this association in the State of Pará by county and Integration Region (IR) from 2007 to 2009 via an analysis of sociodemographic, epidemiological and operational indices. Methods This was a descriptive study using information generated by the SINAN. The Detection Coefficient of the Leprosy and Pregnancy Association (DCLP) epidemiological index was constructed to help interpret the endemicity parameters. The disease was considered hyperendemic when greater than two cases per 10,000 inhabitants were identified. Results During the study period, 149 associations were detected, with 14 hyperendemic counties: seven in 2007, five in 2008 and two in 2009. The Carajás Integrated Region displayed the highest DCLP index in the period. Eldorado dos Carajás had the single highest DCLP index (5.7/10,000 inhabitants, 2008), whereas the DCLP index in Conceição do Araguaia was very high in all three years. However, most counties displayed low or medium DCLP indices. The annual averages were 0.31 DCLP (2007), bass; 0.30 (2008), bass and 0.19 (2009), bass. The average DCLP index was 0.26, which is considered low. Three clusters of medium endemicity were identified by the average DCLP in the study period. Conclusions The analyses indicated that the surveillance program is still unsatisfactory in Pará. The interpretation of the endemicity parameters enabled qualitative and quantitative analyses to determine the epidemiological panorama of this association. The identification of high endemicity requires further clarification.
