Resumo Introdução O conhecimento dos fatores relacionados à perda dentária contribui para o planejamento das ações preventivas realizadas pelas Equipes de Saúde Bucal (ESBs). Objetivo Avaliar o indicador de proporção de exodontia nos municípios do estado de São Paulo e a sua relação com os indicadores socioeconômicos e cobertura das ESBs. Método Estudo ecológico com dados secundários dos 645 municípios do estado de São Paulo do ano de 2012. A variável dependente foi o percentual de exodontia mensurado pelo indicador de proporção de exodontia em relação aos procedimentos individuais realizados pelas ESBs, disponibilizado pelo Sistema de Informação da Atenção Básica. Foram considerados como variáveis independentes a cobertura populacional estimada pelas ESBs, o Produto Interno Bruto (PIB) dos municípios per capita, o Índice de Desenvolvimento Humano (IDH) e o Índice Paulista de Responsabilidade Social (IPRS). Foram aplicados modelos lineares generalizados, avaliados pelo p-valor do teste de Wald, AICC e grau de liberdade. Resultados Apresentaram maior proporção de extrações dentárias as cidades do estado de São Paulo com menor cobertura de ESBs (p < 0,0001), com menor valor de IDH (p < 0,0001) e com maior valor de IPRS (p = 0,0018). Conclusão A baixa cobertura de ESBs e as desigualdades socioeconômicas contribuem para aumentar as extrações dentárias no estado de São Paulo.

Abstract Background Knowledge about factors associated with tooth loss contributes to the planning of preventive actions carried out by Oral Health Teams (OHT). Objective To evaluate the proportion of dental extraction indicator in the cities of the state of São Paulo, Brazil, and its relationship with socioeconomic indicators and coverage of the OHT. Method Ecological study using secondary data from 654 municipalities in the state of São Paulo conducted in 2012. The dependent variable was the percentage of dental extraction measured by the proportion of this indicator in relation to individual procedures performed by the OHT provided by the Primary Health Care (PHC) Information System. The population coverage by the OHT, the per capita Gross Domestic Product (GDP), the Human Development Index (HDI), and the São Paulo Social Responsibility Index (IPRS) of the municipalities were evaluated as independent variables. Generalized linear models, formulated by the Wald test p-value, Corrected Akaike Information Criterion (AICc), and degree of freedom, were applied. Results Higher proportions of dental extraction were found in the municipalities with lower coverage by OHT (p<0.0001), lower HDI value (p<0.0001), and higher IPRS value (p=0. 0018). Conclusion Low coverage by OHT and socioeconomic inequalities contribute to increased proportion of dental extractions in the state of São Paulo.

Cytotoxic Effects of Diclofenac and Ibuprofen Zinc (II)-Nicotinamide Ternary Complexes in Breast Cancer Cell Lines

Abstract Breast cancer is one of the leading types of cancer worldwide, and the search for new treatment options are crucial. Nonsteroidal anti-inflammatory drugs (NSAIDs) -specially ibuprofen and diclofenac-, have shown antitumoral effect against several types of cancer. The synthesis of organometallic compounds has shown significant improvements in pharmacological properties and efficacy of organic molecules. Two zinc II ternary complexes containing the NSAIDs diclofenac and ibuprofen and nicotinamide neutral linker (Nic) were obtained by the two-step solvent metalligand complexation method. The compounds Zn2(Diclof)4(Nic)2 (complex 1) and Zn2(Ibup)4(Nic)2 (complex 2) were tested in breast cancer cell lines (4T1, MCF-7 and MDA-MB-231) to evaluate their cytotoxicity, comparing to ibuprofen and diclofenac as controls. We found that both complex 1 and 2 exerted more than 60% reduction in 4T1 viability at 250µM, and complex 2 decreased cell viability at 250 µM and 137.5 µM in MCF-7 (34.35% and 26.42% reduction, respectively) and in MDA-MB-231 (57.2% and 22.88% reduction, respectively), all compared to controls. Complex 1 was selective only in MCF-7, and complex 2 was selective in both MCF-7 and MDA-MB-231. In summary, our data showed that the cytotoxic effect of complex 1 and 2 is increased comparing to their original NSAID in different breast cancer cell lines, highlighting their potential anti-tumoral activity.

Physical and pulmonary capacities of individuals with severe coronavirus disease after hospital discharge: A preliminary cross-sectional study based on cluster analysis

OBJECTIVE: This study aimed to analyze the physical and pulmonary capacities of hospitalized patients with severe coronavirus disease and its correlation with the time of hospitalization and complications involved. METHODS: A total of 54 patients, aged ≥18 years of both sexes, were evaluated 2-4 months after hospital discharge in São Paulo, Brazil. The physical characteristics analyzed were muscle strength, balance, flexibility, and pulmonary function. The K-means cluster algorithm was used to identify patients with similar physical and pulmonary capacities, related to the time of hospitalization. RESULTS: Two clusters were derived using the K-means algorithm. Patients allocated in cluster 1 had fewer days of hospitalization, intensive care, and intubation than those in cluster 2, which reflected a better physical performance, strength, balance, and pulmonary condition, even 2-4 months after discharge. Days of hospitalization were inversely related to muscle strength, physical performance, and lung function: hand grip D (r=−0.28, p=0.04), Short Physical Performance Battery score (r=−0.28, p=0.03), and forced vital capacity (r=−0.29, p=0.03). CONCLUSION: Patients with a longer hospitalization time and complications progressed with greater loss of physical and pulmonary capacities.

Serum anti-Toxoplasma gondii antibodies in Passer domesticus (Linnaeus, 1758) (Passeriformes: Passeridae), in the municipality of Pelotas, RS, Brazil / Anticorpos séricos anti-Toxoplasma gondii em pardais, Passer domesticus (Linnaeus, 1758) (Passeriformes: Passeridae), do município de Pelotas, RS, Brasil

The objective of this study was to detect the presence of anti-Toxoplasma gondii antibodies in serum samples from 100 house sparrows (Passer domesticus Linnaeus, 1758) that were caught in the municipality of Pelotas, Rio Grande do Sul, Brazil. The modified agglutination test (MAT) was used to investigate anti-T. gondii antibodies and samples with a cut-off dilution > 5 were considered positive. Among the 100 serum samples analyzed, 80 (80%) were reactive. These results demonstrate that P. domesticus may play an important role in the epidemiological chain of T. gondii, since it is widely distributed throughout Brazil, and may act as a source of infection to domestic and wild felids.(AU)

O objetivo deste estudo foi detectar a presença de anticorpos anti-Toxoplasma gondii em amostras de soro de 100 pardais (Passer domesticus Linnaeus, 1758) capturados na área urbana do município de Pelotas, Rio Grande do Sul, Brasil. Para a pesquisa de anticorpos anti-T. gondii foi utilizado o teste de aglutinação modificado (MAT) e foram consideradas positivas as amostras que apresentaram título > 5. Das 100 amostras de soro analisadas, 80 (80%) foram reagentes. Esses resultados demonstram que P. domesticus, por ser amplamente distribuído em todo país, pode desempenhar um papel importante na cadeia epidemiológica de T. gondii, podendo atuar como fonte de infecção para felinos domésticos e silvestres.(AU)

Assistência ao paciente renal antes do início da hemodiálise: estudo retrospectivo / Renal patient care before hemodialysis beginning: a retrospective study

INTRODUCTION: the monitoring of renal patients before the start of hemodialysis is an important element for the implementation of preventive measures that delay or interrupt the progression to more advanced stages of the disease. OBJECTIVE:to evaluate primary and tertiary care for people with Chronic Kidney Disease before hemodialysis. METHODS:retrospective, documentary, quantitative study with 35 renal patients who started hemodialysis in Sobral-Ceará, Brazil. Data were collected between January and March 2015. An instrument was used to outline the socioeconomic profile, laboratory data, etiology of chronic kidney disease, type of vascular access, and degree of comorbidity. In the Family Health Strategy, we sought to collect data on the number and dates of consultations, creatinine levels, qualitative urine tests, and referral to nephrologist. Data were analyzed using descriptive statistics. RESULTS:of the 35 patients, 19 (54.3%) were women and 16 (45.7%) men, with a mean age of 58.8 ± 17.7 years. Of the total, 22 (62.8%) were consulted in the Family Health Strategy before the start of hemodialysis. Of these, only 6 (22.3%) had their renal function assessed and 4 (18.1%) consulted a nephrologist. The time elapsed between the first consultation at the FHS and the start of hemodialysis was 2.5 days (median) and between the first consultation with a nephrologist and the start of hemodialysis, 273.5 days (median). The interval of 2.5 days indicated the start of urgent renal replacement therapy. CONCLUSION:chronic kidney disease is not screened in the majority of patients monitored by the FHS and few are seen by a nephrologist before starting hemodialysis.

O intervalo de 2,5 dias indicou início de urgência da Terapia Renal Substitutiva. Conclusão: a DRC não é rastreada na maioria dos pacientes atendidos na ESF e poucos são atendidos por nefrologista antes de iniciar hemodiálise.

Bone mineral density and body composition in elderly runners: six-year follow-up / Densidade mineral óssea e composição corporal de idosos corredores: follow-up de seis anos

ABSTRACT Objective: To evaluate bone mineral density (BMD) and body composition over a six-year period in elderly long-distance runners. Methods: We analyzed the medical records of elderly athletes who were long-distance runners, were participants of the IOT-HCFMUSP Orthogeriatric Group, and had their BMD evaluated between 2001 and 2007; of these athletes, 11 were included in the study. Inclusion criteria: athletes should be long-distance runners, should not stop long-distance running during the six-year period, and should have undergone BMD and body composition evaluations. Body composition was evaluated using bone densitometry with dual-energy X-ray absorptiometry with a Lunar-DPX device. Results: Over the six-year period, body composition remained stable, but there was a significant increase only in the fat percentage (p = 0.003). Conclusion: Long-distance running may maintain BMD but may lead to an increase in the fat percentage in elderly runners. Level of Evidence II; Prognostic Study - Investigating the Effect of Patient Characteristics on Disease Outcome.

Rhinonyssidae (Acari) in the house sparrows, Passer domesticus (Linnaeus, 1758) (Passeriformes: Passeridae), from southern Brazil / Ácaros nasais Rhinonyssidae parasitos de Passer domesticus (Linnaeus, 1758) (Passeriformes: Passeridae) no extremo sul do Brasil

Abstract We report the occurrence and infection parameters of two species of nasal mites in Passer domesticus (Linnaeus, 1758) (house sparrow). Nasal passages, trachea, lungs, and air sacs of 100 house sparrows captured in an urban area at the city of Pelotas, State of Rio Grande do Sul, southern Brazil, were examined with a stereomicroscope. The mite, Sternostoma tracheacolum Lawrence, 1948 was present in the trachea and/or lungs (or both) of 13 birds (13%) at a mean intensity of 6.7 mites/infected host. Ptilonyssus hirsti (Castro & Pereira, 1947) was found in the nasal cavity of 1 sparrow (1%); coinfection was not observed in this bird. There was no significant difference in the prevalence and mean intensity of infection of S. tracheacolum between male and female birds. To our knowledge, this is the first study reporting the occurrence of S. tracheacolum in P. domesticus in Brazil and the presence of P. hirsti in P. domesticus from Rio Grande do Sul, Brazil. This is the first survey to provide the infection parameters of each of these mites in house sparrows.

Resumo O objetivo deste estudo foi relatar duas espécies de ácaros nasais parasitos do sistema respiratório de Passer domesticus (Linnaeus, 1758) (pardal) e seus respectivos índices parasitológicos. Para isso, foram examinados ao estereomicroscópio, cavidade nasal, traqueia, pulmão e sacos aéreos de 100 pardais capturados na área urbana de Pelotas, Rio Grande do Sul, Brasil. Sternostoma tracheacolum Lawrence, 1948 ocorreu na traqueia e/ou pulmão de 13 aves (13%) com intensidade média de 6,7 ácaros/hospedeiro infectado e Ptilonyssus hirsti (Castro & Pereira, 1947) na cavidade nasal de um único pardal (1%), não havendo coinfecção. A prevalência e intensidade média de infecção por S. tracheacolum entre hospedeiros machos e fêmeas não apresentou diferença significativa. Este relato caracteriza o primeiro registro de S. tracheacolum parasitando P. domesticus no Brasil e de P. hirsti em pardais no RS, Brasil, e seus respectivos índices de infecção.

Variables associated with lung congestion as assessed by chest ultrasound in diabetics undergoing hemodialysis / Variáveis associadas a congestão pulmonar avaliada por ultrassonografia em diabéticos submetidos a hemodiálise

Abstract Introduction: Ultrasound is an emerging method for assessing lung congestion but is still seldom used. Lung congestion is an important risk of cardiac events and death in end-stage renal disease (ESRD) patients on hemodialysis (HD). Objective: We investigated possible variables associated with lung congestion among diabetics with ESRD on HD, using chest ultrasound to detect extracellular lung water. Methods: We studied 73 patients with diabetes as the primary cause of ESRD, undergoing regular HD. Lung congestion was assessed by counting the number of B lines detected by chest ultrasound. Hydration status was assessed by bioimpedance analysis and cardiac function by echocardiography. The collapse index of the inferior vena cava (IVC) was measured by ultrasonography. All patients were classified according to NYHA score. Correlations of the number of B lines with continuous variables and comparisons regarding the number of B lines according to categorical variables were performed. Multivariate linear regression was used to test the variables as independent predictors of the number of B lines. Results: None of the variables related to hydration status and cardiac function were associated with the number of B lines. In the multivariate analysis, only the IVC collapse index (b = 45.038; p < 0.001) and NYHA classes (b = 13.995; p = 0.006) were independent predictors of the number of B lines. Conclusion: Clinical evaluation based on NYHA score and measurement of the collapsed IVC index were found to be more reliable than bioimpedance analysis to predict lung congestion.

Resumo Introdução: A ultrassonografia é um método emergente e ainda raramente utilizado na avaliação da congestão pulmonar. A congestão pulmonar é um importante fator de risco para eventos cardíacos e óbito entre pacientes com doença renal terminal (DRT) em hemodiálise (HD). Objetivo: Foram investigadas as possíveis variáveis associadas a congestão pulmonar em indivíduos diabéticos com DRT em HD, utilizando a ultrassonografia torácica para detectar água extracelular nos pulmões. Métodos: Foram estudados 73 pacientes com diabetes como causa primária de DRT submetidos a HD regular. A congestão pulmonar foi avaliada pela contagem do número de linhas B detectadas por ultrassonografia torácica. O estado de hidratação foi avaliado por análise de bioimpedância e a função cardíaca por ecocardiografia. O índice de colabamento da veia cava inferior (VCI) foi medido por ultrassonografia. Todos os pacientes foram classificados segundo a escore da NYHA. Foram analisadas as correlações entre o número de linhas B e variáveis contínuas e as comparações entre o número de linhas B em relação às variáveis categóricas. Regressão linear multivariada foi utilizada para testar as variáveis enquanto preditores independentes do número de linhas B. Resultados: Nenhuma das variáveis relacionadas a estado de hidratação e função cardíaca apresentou associação com o número de linhas B. Na análise multivariada, apenas o índice de colabamento da VCI (b = 45,038; p < 0,001) e as classes da NYHA (b = 13,995; p = 0,006) foram preditores independentes do número de linhas B. Conclusão: A avaliação clínica baseada na classificação da NYHA e na medição do índice de colabamento da VCI foram mais confiáveis do que a análise de bioimpedância para predizer congestão pulmonar.

Tratamento por ondas de choque extracorpórea na síndrome do estresse tibial: uma revisão da literatura / Treatment of medial tibial stress syndrome with extracorporeal shockwave treatment: a literature review

A síndrome do estresse tibial medial é uma lesão comum devido a sobrecarga mecânica, principalmente em atletas, devido a inflamação local e estresse ósseo. A terapia de ondas de choque (TOC) vem sendo utilizada como tratamento para esta patologia por seus efeitos analgésicos e anti-inflamatórios. Objetivo: Avaliar a eficácia da TOC no tratamento analgésico da síndrome do estresse tibial medial e medidas de funcionalidade. Métodos: Foi realizada uma revisão da literatura, sendo incluídos estudos clínicos em humanos. Resultados: 3 artigos preencheram os critérios de inclusão, incluindo 166 pacientes. Os trabalhos trouxeram uma ampla variedade de intervenções, tipos de aparelhos, frequência e energia utilizada, além de diferenças nas quantidades de sessões e tipos de ondas de choque utilizado no tratamento. Conclusão: Ainda não há evidências consistentes quanto ao uso da TOC no tratamento conservador da síndrome do estresse tibial medial, com estudos pequenos, de qualidade metodológica baixa. Os estudos inclusos no trabalho não relataram efeitos colaterais significativos

Medial tibial stress syndrome is a common injury due to mechanical overload, especially in athletes due to local inflammation and bone stress. Shockwave therapy (ESWT) has been used as a treatment for this pathology due to its analgesic and anti-inflammatory effects. Objective: To evaluate the effectiveness of ESWT in the analgesic treatment of medial tibial stress syndrome and measures of functionality. Methods: A review of the literature was conducted, with clinical studies in humans included. Results: 3 articles fulfilled the inclusion criteria, including 166 patients. The trials involved a wide variety of interventions, types of devices, frequency and energy used, as well as differences in the number of sessions and types of shock waves used in treatment. Conclusion: There is still no consistent evidence regarding the use of ESWT in the conservative treatment of medial tibial stress syndrome, with small studies of low methodological quality. Studies included in this review did not report significant side effects

Spatial distribution of envenomation by scorpions in Pará state, Brazil

Scorpionism is recognized by the World Health Organization as a neglected disease and, in Pará State, Brazil, it is considered a public health hazard. The objective of this study was to describe the spatial distribution of envenomation caused by scorpions in Pará. The data related to envenomation were collected from 2007 to 2014 and used for both descriptive and transversal studies. For those studies records obtained from ongoing investigations from the database of the National Notifiable Diseases Information System at the Public Health Department of Pará State were used. Envenomation occurs year round, most often in the first half of the year, in males from the countryside, aged 20 to 59 years and taking up to 3 hours to reach medical care. The deaths occurred from ages 15 to 59. Regarding the severity of the cases, class I cases were the most frequent and class III cases were the least frequent, accounting for only 5.1% of all cases. Of the 144 municipalities of Pará State, in 126 the frequency of envenomation ranged from 1 to 1,208 cases per municipality. Thirteen municipalities located in the lower Amazon region and in the southwest of Pará State presented higher occurences, including the highest number of deaths. Scorpionism is present throughout Pará State. However, there were differences in severity and incidence in the various regions, with higher frequency in the southwest of the State and in the lower Amazon region, corresponding to the Tapajós and Guyana endemic areas in the Brazilian Amazon.

Aplicação do questionário SCORED para rastreamento da doença renal crônica entre pacientes hipertensos e diabéticos / Application of the SCORED questionnaire for the screening of chronic kidney disease among patients with hypertension and diabetes

Resumo Introdução O questionário SCORED foi desenvolvido para predizer a probabilidade de um indivíduo apresentar doença renal crônica (DRC). O estudo teve por objetivo avaliar o desempenho do SCORED entre hipertensos e diabéticos cadastrados na unidade-sede da Estratégia Saúde da Família (ESF), na cidade de Meruoca, no Estado do Ceará. Métodos A amostra foi formada por 221 participantes. A taxa de filtração glomerular de <60 mL/min foi utilizada como padrão-ouro para o diagnóstico da DRC. Foram calculadas as propriedades de acurácia, sensibilidade, especificidade e likelihood ratios positivo e negativo do instrumento SCORED para o diagnóstico da DRC. Resultados Os resultados do desempenho do SCORED foram os seguintes: a pontuação gerada pelo SCORED foi preditora independente da presença de DRC (OR=1,261; IC95%=1,108-1,597; p=0,049); o questionário apresentou sensibilidade de 97% e especificidade de 23% em diagnosticar DRC, com likelihood ratio positivo de 1,25 e negativo de 0,13, além de acurácia de 47%. Alta sensibilidade e baixo likelihood ratio negativo habilitam o SCORED como instrumento de rastreamento de DRC entre hipertensos e diabéticos. Conclusão A utilização desse questionário tem o potencial de incrementar o diagnóstico precoce da DRC entre pacientes cadastrados na ESF, além de sua aplicabilidade na população geral e em campanhas educacionais.

Abstract Introduction A questionnaire named SCORED was developed in order to predict the probability of an individual chances of having chronic kidney disease (CKD). We aimed to evaluate the performance of SCORED among hypertensives and diabetics registered with the Family Health Strategy (FHE) program in the city of Meruoca, Ceará, Brazil. Methods 221 participants formed the sample. Glomerular filtration rate <60 mL/min was used as gold standard for CKD diagnosis. We calculated accuracy, sensitivity, specificity and positive and negative likelihood ratios of the SCORED tool for the diagnosis of CKD. Results Results of SCORED performance were the following: the score generated was an independent predictor of CKD (OR=1.261; CI 95%=1.108-1.597; p=0.049); the questionnaire had 97% sensitivity and 23% specificity in diagnosing CKD, with positive likelihood ratio of 1.25 and negative of 0.13, and accuracy of 47%. High sensitivity and low negative likelihood ratio enables SCORED to be used as a screening tool for CKD among hypertensive and diabetic people. Conclusion The use of this questionnaire has the potential to increase early diagnosis of CKD among patients registered with the FHE, besides its applicability to the general population and in educational campaigns.

Scorpionism by Tityus silvestris in eastern Brazilian Amazon

Background Scorpionism is a serious public health problem in Brazil. Although cases of envenomation by scorpions are frequent in Brazil, Tityus silvestris - found throughout the Amazon region - is considered of minor medical significance and with only a few descriptions in the literature. This article aims to describe for the first time the epidemiological characteristics and clinical manifestations of scorpion stings by T. silvestris that occurred in eastern Brazilian Amazon. Methods A prospective and observational study was carried out on 13 confirmed cases of T. silvestris envenomation registered from 2007 to 2011 in the cities of Belém and Ananindeua, Pará state, Brazil. Results The stings occurred mainly during daytime, at domiciliary environment, and the scorpions were found in clothing, fruits or vegetables. Envenomation was more frequent in the age group between 21 and 30 years old, upper limbs were more affected and medical aid was usually provided within two hours. Men and women were equally affected. Regarding severity, ten patients were classified as Class I and three patients as Class II according to the Scorpion Consensus Expert Group. Local manifestations were present in all patients, being pain the most common symptom. Mild systemic manifestations including nausea, vomiting, somnolence, malaise and prostration were observed in three victims. Symptomatic treatment of pain was offered to all patients, and only one received specific antivenom. All victims had a favorable outcome. Conclusions To the best of our knowledge, this study is the first to report the systemic symptomatology of envenomation by T. silvestris in the Brazilian Amazon, highlighting the medical relevance of the species in this region. Further research on the venom and clinical manifestations of envenomation by T. silvestris should be conducted in order to verify the relevance of this species to public health.(AU)

Nefropatia induzida por contraste após angioplastia primária no infarto agudo do miocárdio / Contrast-induced nephropathy after primary angioplasty for acute myocardial infarction

Resumo Introdução: A prevenção da nefropatia induzida por contraste (NIC) é difícil nas situações de emergência, tornando essenciais estudos sobre NIC em pacientes submetidos à angioplastia de urgência. Objetivo: Determinar a incidência e fatores associados à NIC em pacientes com infarto agudo do miocárdio (IAM) submetidos à angioplastia nas primeiras 12 horas após início dos sintomas. Métodos: Foram estudados 201 casos consecutivos de IAM com supradesnivelamento do segmento ST com menos de 12 horas de evolução. Todos os pacientes foram submetidos ao mesmo protocolo de angioplastia. A NIC foi definida como elevação absoluta da creatinina de pelo menos 0,5 mg/dL e/ou aumento relativo da creatinina de 25% em relação ao valor basal no período entre 48 e 72 horas após a administração do contraste. As variáveis que diferiram entre os pacientes com e sem NIC na análise univariada foram analisadas por regressão logística. Resultados: A amostra foi formada por 135 (67,2%) homens e 66 (32,8%) mulheres com idade média de 66,6 ± 11,7 anos. A incidência de NIC foi de 23,8%. Na análise univariada os pacientes com NIC eram mais idosos e com maior frequência de fração de ejeção do ventrículo esquerdo ≤ 40% e da classificação Killip ≥ 2. Na análise multivariada não foram encontrados preditores independentes de NIC. Conclusão: A NIC acomete » dos pacientes com IAM submetidos à angioplastia sem variáveis preditoras. Esse resultado ressalta a necessidade de medidas preventivas para NIC após uso de contraste em angioplastia de urgência.

Abstract Introduction: The prevention of contrast-induced nephropathy (CIN) is difficult in emergency situations, making it essential to study CIN in patients submitted to urgent angioplasty. Objective: To determine the incidence and associated factors to CIN in patients with myocardial infarction (MI) submitted to primary angioplasty in the first 12 hours after onset of symptoms. Methods: We studied 201 consecutive cases of MI with ST-segment elevation with less than 12 hours of evolution. All patients were submitted to the same angioplasty protocol. CIN was defined as an absolute increase of creatinine of at least 0.5 mg/dL and/or a relative increase of creatinine of 25% in relation to baseline in a period between 48 and 72 hours after contrast administration. The variables that differed between patients with and without CIN in univariate analysis were analyzed by logistic regression. Results: The sample was formed by 135 (67.2%) men and 66 (32.8%) women, with mean age of 66.6 ± 11.7 years. The incidence of CIN was 23.8%. In univariate analysis the patients with CIN were older and had higher frequency of left ventricular ejection fraction ≤ 40% and Killip classification ≥ 2. In multivariate analysis, we did not find independent predictors of CIN. Conclusion: CIN occurred in » of the patients with MI submitted to angioplasty without predictor variables. This finding highlights the need for CIN preventive measures after contrast use in emergency angioplasty.

Comparison of baseline data between chronic kidney disease patients starting hemodialysis who live near and far from the dialysis center / Comparação dos dados de base entre pacientes com doença renal crônica que iniciam hemodiálise que moram perto e longe da unidade de diálise

Introduction: The treatment offered to chronic kidney disease (CKD) patients before starting hemodialysis (HD) impacts prognosis. Objective: We seek differences among incident HD patients according to the distance between home and the dialysis center. Methods: We included 179 CKD patients undergoing HD. Patients were stratified in two groups: "living near the dialysis center" (patients whose hometown was in cities up to 100 km from the dialysis center) or as "living far from the dialysis center" (patients whose hometown was more than 100 km from the dialysis center). Socioeconomic status, laboratory results, awareness of CKD before starting HD, consultation with nephrologist before the first HD session, and type of vascular access when starting HD were compared between the two groups. Comparisons of continuous and categorical variables were performed using Student's t-test and the Chi-square test, respectively. Results: Ninety (50.3%) patients were classified as "living near the dialysis center" and 89 (49.7%) as "living far from the dialysis center". Patients living near the dialysis center were more likely to know about their condition of CKD than those living far from the dialysis center, respectively 46.6% versus 28.0% (p = 0.015). Although without statistical significance, patients living near the dialysis center had more frequent previous consultation with nephrologists (55.5% versus 42.6%; p = 0.116) and first HD by fistula (30.0% versus 19.1%; p = 0.128) than those living far from the dialysis center. Conclusion: There are potential advantages of CKD awareness, referral to nephrologists and starting HD through fistula among patients living near the dialysis center. .

Introdução: O tratamento da doença renal crônica (DRC) anterior ao início da hemodiálise (HD) tem impacto sobre o prognóstico. Objetivo: Comparar diferenças entre pacientes incidentes em HD de acordo com a distância entre moradia e a unidade de diálise. Métodos: Foram incluídos 179 pacientes com DRC em HD. Os pacientes foram divididos em dois grupos: "residentes perto da unidade de diálise" (moradia até 100 km da unidade de diálise) e "residentes longe da unidade de diálise" (moradia a mais de 100 km da unidade de diálise). Nível socioeconômico, resultados laboratoriais, conhecimento sobre DRC antes de iniciar HD, consulta com nefrologista antes da primeira sessão de HD e tipo de acesso vascular ao iniciar HD foram comparados entre os dois grupos. As comparações entre variáveis contínuas e categóricas foram feitas pelos testes t de Student e qui-quadrado, respectivamente. Resultados: Noventa (50,3%) pacientes foram classificados como "morando perto" e 89 (49,7%) "morando longe". Havia mais pacientes morando perto da unidade de diálise com conhecimento sobre DRC do que os pacientes morando longe, respectivamente, 46,6% versus 28,0% (p = 0,015). Mesmo sem significado estatístico, havia mais pacientes morando perto da unidade de diálise que se consultaram previamente com nefrologista (55,5% versus 42,6%; p = 0,116) e que iniciaram HD por fístula (30,0% versus 191,1%; p = 0,128) do que os pacientes morando longe. Conclusão: Existem vantagens potenciais em relação ao conhecimento da DRC, encaminhamento ao nefrologista e início de HD por fístula entre os pacientes que moram perto da unidade de diálise. .

Avaliação da acessibilidade ao Centro de Especialidades Odontológicas de abrangência macrorregional de Sobral, Ceará, Brasil / Evaluation of the accessibility to the Specialized Dental Care Center within the scope of the macro region of Sobral, in the state of Ceará, Brazil

O Centro de Especialidades Odontológicas Regional de Sobral (CEO-R), no Ceará, possui características que o tornam único: tem abrangência regional, é administrado por um Consórcio intermunicipal de Saúde (totalizando 24 municípios) e funciona juntamente com o Curso de Odontologia da Universidade Federal do Ceará - Campus Sobral, congregando no mesmo espaço serviço e academia. O objetivo desta pesquisa foi avaliar a acessibilidade à atenção especializada nesta região após a implantação do CEO-R Sobral. Foi realizado um estudo exploratoìrio-descritivo, com abordagem quantitativa, por meio da coleta e análise de dados secundários de oferta e utilização desse serviço, além da aplicação de entrevista semiestruturada aos Coordenadores de Saúde Bucal dos 24 municiìpios consorciados. Os resultados evidenciaram que o CEO-R está preparado para atender à demanda. Contudo, foram encontradas barreiras geográficas, financeiras e organizacionais que explicam as baixas taxas de aproveitamento de marcação de consultas e de utilização do serviço e a alta taxa de faltosos, causando um importante impacto financeiro para os municípios consorciados.

The Specialized Dental Care Center for the region of Sobral in the state of Ceará (CEO-R) has characteristics that render it unique, as it has regional coverage and is managed by a Local Health Consortium (which comprises 24 cities). It also works in conjunction with the School of Dentistry of the Federal University of Ceará - Sobral Campus, combining care and academic study in the same location. The scope of this article was to evaluate the accessibility to specialized care in this region with the implementation of this CEO-R. A descriptive-exploratory study with a quantitative approach was conducted by means of the collection and analysis of secondary data regarding the availability and usage of this service in addition to the application of semi-structured interviews with Oral Health Coordinators of the 24 municipalities in the consortium. The results showed that the CEO-R is equipped to meet the demand. However, geographic, financial and organizational barriers were detected, which explains the low rates of appointments scheduled and use of the services and the high rate of missed appointments, causing a significant financial impact on the cities included in the consortium.

Report of four cases of Bardet-Biedl syndrome / Relato de quatro casos da síndrome de Bardet-Biedl

Bardet-Biedl syndrome is rare. Although its diagnosis depends on cardinal clinical manifestations which appear in childhood, we report four cases of Bardet-Biedl syndrome lately diagnosed in a dialysis center. Three cases were diagnosed in end-stage renal disease patients when they started maintenance hemodialysis, and one case was diagnosed through screening among hemodialysis patients' relatives. Although pediatricians have more opportunity to diagnose the syndrome, nephrologists are important during the treatment, since renal failure is the main cause of death among Bardet-Biedl syndrome patients. Moreover, late diagnosis of the syndrome among patients with end-stage renal disease can help to detect new cases through the screening among hemodialysis patients' relatives.

A síndrome de Bardet-Biedl é rara. Embora seu diagnóstico seja baseado em manifestações cardinais que aparecem na infância, relatamos quatro casos de síndrome de Bardet-Biedl diagnosticados tardiamente em uma unidade de diálise. Três casos foram diagnosticados em pacientes com doença renal crônica terminal quando iniciaram hemodiálise de manutenção, e um caso diagnosticado por meio de rastreamento dos parentes dos casos em diálise. Embora pediatras tenham mais oportunidade para diagnosticar a síndrome, nefrologistas são importantes durante o tratamento, já que a insuficiência renal é a principal causa de óbito entre os pacientes com síndrome de Bardet-Biedl. Além disso, o diagnóstico tardio da síndrome entre pacientes com doença renal crônica terminal pode ajudar a detecção de casos novos por meio do rastreamento de parentes dos pacientes em hemodiálise.
