RESUMEN
Introduction: We must study alternatives to structure an effective diabetic retinopathy screening program for Brazilian public health system. Objectives: Evaluate the diagnostic performance of retinal digital photography for diabetic retinopathy screening in primary care, accuracy of the family physician in diabetic retinopathy identification compared to the ophthalmologist, and the need for dilation. Methodology: In a primary care service were performed retinal photographs with non-mydriatic Retinal Camera in 219 type 2 diabetic patients with and without medication mydriasis. We evaluated the performance of the diagnostic of the photos graded by three family physicians with training compared to two ophthalmologists (gold standard), and explore related factors with the need for mydriasis pharmacologically. Results: The prevalence of diabetic retinopathy and proliferative diabetic retinopathy was 19.2% and 1.5%, respectively. The sensitivity of family physicians to evaluate diabetic retinopathy averaged 82.9% (66.7-94.8%); specificity, 92% (90.2-93.3%); the accuracy, 90.3% (88.2-93%) and positive predictive value, 71.2% (68-75.5%). The agreement calculated using the kappa adjusted coefficient was from 0.74 to 0.8 for retinopathy and 0.88 to 0.92 for macular edema. Without drug mydriasis the photos were unreadable by 14.8%, when using mydriatic collyrium this number decreased to 8.7% (McNemar test, P < 0.005). Patients with more than 65 years old has more readability after drug mydriasis (McNemar test, P = 0.011). Conclusion: Trained family physician reached a good performance for evaluation of retinography for diabetic retinopathy. There was improvement in readability with pupil dilation in older patients.

RESUMO Este estudo objetivou analisar encaminhamentos de pessoas a serviços de cardiologia e endocrinologia pelos médicos da Atenção Primária à Saúde (APS) de um município do Rio Grande do Sul. Estudo transversal com questionários a 25 médicos da APS, 2 cardiologistas, 2 endocrinologistas e 1 médico regulador. A análise estatística foi realizada no SPSS, sendo as variáveis contínuas apresentadas como média ou mediana; e as variáveis categóricas, como frequência absoluta e relativa. Entre os médicos da APS, 96% conhecem, 84% utilizam protocolos de encaminhamento e 92% encaminham os pacientes principalmente para manejo de doenças complicadas que necessitam de avaliação do especialista. Entre os especialistas, 50% conhecem os protocolos, e todos apontam que o principal motivo de encaminhamentos para eles ocorre devido a condições crônicas prevalentes mal controladas na APS, sendo considerados pelos endocrinologistas como mal indicados. O médico regulador avalia que a maioria dos documentos de encaminhamento é incompleta e não permite verificar a gravidade do problema. Conclui-se que os protocolos de encaminhamento não estão sendo utilizados de forma a otimizar os fluxos dos usuários na rede de atenção à saúde, indicando a necessidade de revisão de processos de trabalho, capacitação dos profissionais e articulação entre APS, regulação e Atenção Especializada.
ABSTRACT This study aimed to analyze referrals of people to cardiology and endocrinology services by doctors in Primary Health Care (PHC) in a city in Rio Grande do Sul. Cross-sectional study with questionnaires applied to 25 PHC doctors, 2 cardiologists, 2 endocrinologists and 1 regulatory doctor. Statistical analysis was performed in SPSS, with continuous variables being presented as mean or median; and categorical variables, such as absolute and relative frequencies. Among PHC doctors, 96% know, 84% use referral protocols, and 92% refer patients mainly to manage complicated diseases that require specialist evaluation. Among the specialists, 50% know the protocols, and all point out that the main reason for referrals to them occurs due to prevalent chronic conditions poorly controlled in PHC, being considered by endocrinologists as poorly indicated. The regulatory doctor assesses that most referral documents is incomplete and does not allow to verify the seriousness of the problem. It is concluded that the referral protocols are not being used in order to optimize the flow of users in the health care network, indicating the need for review of work processes, training of professionals and articulation between PHC, regulation and Specialized Care.
RESUMEN
ABSTRACT Objective This study aimed to establish the utility values of different health states associated with diabetic retinopathy in a Brazilian sample to provide input to model-based economic evaluations. Subjects and methods This cross-sectional study was performed in a sample of patients with type 2 diabetes mellitus (T2D) who underwent teleophthalmology screening at a primary care service from 2014 to 2016. Five diabetic retinopathy health states were defined: absent, non-sight-threatening, sight-threatening, and bilateral blindness. Utility values were estimated using the Brazilian EuroQol five dimensions (EQ-5D) tariffs. Descriptive statistics were calculated. Analysis of covariance was performed to adjust the utility values for potential confounders. Results The study included 206 patients. The mean (± standard deviation [SD]) utility value was 0.765 ± 0.19 (95% confidence interval [CI], 0.740-0.790). The adjusted mean utility value was 0.748 (95% CI, 0.698-0.798) in patients without diabetic retinopathy, 0.752 (95% CI, 0.679-0.825) in those with non-sight-threatening state, 0.628 (95% CI, 0.521-0.736) in those with sight-threatening state, and 0.355 (95% CI, 0.105-0.606) in those with bilateral blindness. A significant utility decrement was found between patients without diabetic retinopathy and those with a sight-threatening health state (0.748 vs. 0.628, respectively, p = 0.04). Conclusions The findings suggest that a later diabetic retinopathy health state is associated with a decrement in utility value compared with the absence of retinopathy in patients with T2D. The results may be useful as preliminary input to model-based economic evaluations. Further research is needed to investigate the impact of diabetic retinopathy on health-related quality of life in a sample more representative of the Brazilian population.

Abstract Introduction Pneumatization of the maxillary sinus may make it impossible to insert implants directly in the posterior region of the maxilla, and in these cases, the solution is to submit the patient to maxillary sinus floor augmentation surgery. The most common complication of this surgery is sinus membrane perforation. Anatomical variations of the internal space of the sinus, such as the bone septa, may further hamper detachment of this membrane. Objective To evaluate the prevalence and characteristics of sinus septa in patients from the Zona da Mata Mineira (Minas Gerais, Brazil), to offer relevant information for a safer planning of surgeries involving this region. Material and method A total of 120 patients (240 sinuses) were analyzed using cone-beam computed tomography (CBCT) images, verifying the presence of sinus septa and classifying them for size and anteroposterior location. Result Of the 120 patients analyzed, 45 (37.50%) had sinus septa, 66 septa in total. Of these, 33 (50%) were present in the middle region of the maxillary sinus and the mean septum size was 7.23 mm. There was no significant difference in the septum size between the genders or between the right and left sides. Conclusion The high rates of incidence of sinus septa justify their study, which should be based mainly on accurate exams, such as CBCT, since they represent one of the most relevant anatomical variations for the cases of sinus surgeries.
Resumo Introdução A pneumatização do seio maxilar pode impossibilitar a instalação direta de implantes na região posterior da maxila, e a solução nesses casos é submeter o paciente a uma cirurgia de levantamento do assoalho do seio maxilar. A complicação mais comum dessa cirurgia é a perfuração da membrana sinusal. Variações anatômicas no interior do seio como, por exemplo, os septos ósseos, podem dificultar ainda mais o descolamento dessa membrana. Objetivo Avaliar a prevalência e as características dos septos sinusais em pacientes da Zona da Mata Mineira (Minas Gerais, Brasil), oferecendo informações relevantes para um planejamento mais seguro das cirurgias envolvendo essa região. Material e método Um total de 240 seios (120 pacientes) foram analisados, por meio de imagens de tomografia computadorizada de feixe cônico (TCFC), verificando-se a presença de septos sinusais e classificando-os quanto ao tamanho e à localização anteroposterior. Resultado Dos 120 pacientes analisados, 45 (37,50%) apresentaram septos sinusais, sendo 66 septos no total. Destes, 33 (50%) estavam presentes na região média do seio maxilar e o tamanho médio dos septos foi de 7,23 mm. Não existiu diferença significativa no tamanho dos septos entre os sexos ou entre os lados direito e esquerdo. Conclusão As elevadas taxas de incidência dos septos sinusais justificam o seu estudo, que deve ser baseado principalmente em exames acurados, como a TCFC, uma vez que representam uma das variações anatômicas mais relevantes para os casos de cirurgias de levantamentos de seio.

Type 2 diabetes mellitus accounts for 90% of diabetes cases and is associated with macro- and microvascular complications of high morbidity and mortality. Individuals with increased risk for type 2 diabetes include those with impaired fasting glucose (IFG), impaired glucose tolerance (IGT), and especially those with combined IFG and IGT. These individuals are part of a group known as prediabetes patients. Approximately 25% of individuals with prediabetes will develop type 2 diabetes in three to five years. Hyperglycemia, in the absence of diabetes, is also associated with increased risk of cardiovascular disease. Studies have shown that changes in lifestyle and drug interventions are effective in delaying or preventing type 2 diabetes in patients with prediabetes. Metformin is the drug of choice when medical treatment is warranted. IGT and IFG are associated with type 2 diabetes and, despite controversy, most studies reinforce the importance of these conditions in the development of micro- and macrovascular disease. Thus, therapeutic interventions in patients with prediabetes are important in primary prevention of type 2 diabetes and its chronic complications.

INTRODUÇÃO: A tuberculose merece especial atenção dos profissionais de saúde e da sociedade. Entretanto, os serviços de saúde não estão organizados para atender esses pacientes, e a prevalência da doença permanece alta no país. O objetivo deste estudo é demonstrar o papel da Atenção Primária na melhora dos indicadores da Tuberculose a partir de ações programáticas estruturadas. MÉTODOS: Dados de pacientes com diagnóstico de TB vinculados à Unidade Básica de Saúde do Hospital de Clínicas de Porto Alegre, atendidos nos serviços de saúde do município, foram analisados e comparados antes (2002 a 2008) e depois (2009 a 2012) da implantação de um Programa de Controle de Tuberculose. Os indicadores analisados têm base nas metas estabelecidas pela Organização Mundial da Saúde. RESULTADOS: Cento e quarenta pacientes tiveram Tuberculose entre 2002 e 2012: 94 no período pré-implantação do Programa e 46 após. Com o Programa, o número anual de sintomáticos respiratórios rastreados e de pacientes diagnosticados com Tuberculose cresceu. Aumentou o diagnóstico de Tuberculose nos serviços de atenção primária de 4,3% (n = 4) para 39,1% (n = 18), (p < 0,001); e houve melhora das taxas de cura (de 78,2% para 85,7%) e abandono (de 9,3% para 9,1%). CONCLUSÃO: Nosso estudo demonstrou que após a implantação do Programa de Controle de TB no Serviço de APS do HCPA houve melhora nos índices de diagnóstico da doença, nas taxas de cura e abandono, tendo sido atingida a meta de cura preconizada pelo Ministério da Saúde
INTRODUCTION: Tuberculosis deserves special attention from health professionals and society. However, health services are not organized to attend these patients, and the prevalence of the disease remains high in the country. The objective of this paper is to demonstrate the role of primary care in improving tuberculosis indicators with structured programmatic actions METHODS: Data from patients diagnosed with tuberculosis linked to the Primary Health Care Service of the Hospital de Clínicas de Porto Alegre, attended in the health care services of the city, were analyzed and compared before (2002-2008) and after (2009-2012) the implementation of a Tuberculosis Control Program. The indicators were analyzed based on the goals established by WHO. RESULTS: One hundred and forty patients had tuberculosis between 2002 and 2012, 94 before the implementation of the Program and 46 after. With the Program, the annual number of tracked respiratory symptomatic patients and patients diagnosed with tuberculosis increased. Also, the diagnosis of tuberculosis in primary care services increased from 4.3% (n = 4) to 39.1% (n = 18) (p < 0.001); and there was an improvement in cure (78.2% to 85.7%) and therapy dropout (9.3% to 9.1%) rates. CONCLUSION: Our study showed that, after implementation of the Tuberculosis Control Program in the Primary Health Care Service of the Hospital de Clínicas de Porto Alegre, there was improvement in diagnosis of the disease, cure and treatment dropout rates, which have reached the cure rate goal established by the Ministry of Health

O diabetes melito do tipo 2 (DM2) é responsável por 90% dos casos de diabetes e está associado a complicações micro e macrovasculares de elevada morbimortalidade. Os indivíduos com maior risco de desenvolvimento de DM incluem aqueles com glicemia de jejum alterada (GJA) e tolerância diminuída à glicose (TDG) e especialmente aqueles com as duas condições combinadas. Esses indivíduos fazem parte de um grupo hoje conhecido como pré-diabetes. Aproximadamente 25% dos indivíduos com pré-diabetes desenvolverão DM2 em três a cinco anos. A hiperglicemia, na ausência de DM, também foi associada ao aumento no risco de doença cardiovascular. Estudos demonstraram que mudanças no estilo de vida e intervenções medicamentosas são efetivas em retardar ou prevenir o DM2 em pacientes com pré-diabetes. GJA e TDG estão associadas ao desenvolvimento de DM2 e, apesar das controvérsias, a maioria dos estudos epidemiológicos reforça a importância dessas duas condições também no desenvolvimento de doença micro e macrovascular. Assim, intervenções em pacientes com pré-diabetes são importantes na prevenção primária do DM2 e de suas complicações crônicas.
