RESUMEN

The World Health Organization recommends conducting prevalence surveys to validate the elimination of trachoma as a public health problem by the year 2030. The recommendation specifies that the surveys should be directed to previous endemic poor rural areas. Brazil is an endemic country for trachoma and has experienced a large internal migration from the rural areas to the outskirts of the major cities. This study aimed to determine the prevalence of trachoma in children aged 1 to 9 years old in two of the poorest municipalities on the outskirts of Sao Paulo to test the hypothesis of whether internal migration brought trachoma with it. A household survey was conducted between 2013 and 2014. The field teams went door-to-door to collect data on households with children of the selected age group and their members. The trachoma prevalence in this group was 1.5% (79/5,393). In the 10 to 19 years old group, the trachoma prevalence was significantly higher among girls 3.2% (47/1,448) than among boys 1.5% (20/1,361). This result adds evidence to the elimination of trachoma as a public health problem and will be included in the supporting material to validate its elimination in Brazil.

RESUMEN

Introdução: Tracoma é uma doença infecciosa ocular, reconhecido como uma importante causa de cegueira, afetando, principalmente, indivíduos que vivem em regiões quentes e secas, com precárias condições de saneamento básico, higiene e associado ao baixo nível educacional dos pais. Segundo a Organização Mundial de Saúde (OMS), o tracoma ativo afeta cerca de 21 milhões de pessoas, com cerca de 2,2 milhões de cegos ou deficientes visuais graves e 2 milhões possuem triquíase. A transmissão pode ser direta ou indireta e ocorre principalmente em crianças. O tratamento é feito com Azitromicina em dose única e caso a doença não seja tratada, com o passar do tempo, pode causar cegueira. Para considerar o tracoma eliminado como um problema de saúde pública a prevalência deve ser menor do que 5%. Métodos: O estudo foi realizado em crianças pré-escolares de 1 a 5 anos e escolares de 6 a 9 anos de idade, no município de Pirapora do Bom Jesus, estado de São Paulo(AU...)

RESUMEN

PURPOSE: Trachoma was hyperendemic in Brazil until the 20th century. The prevalence has declined sharply in the past decades. The aim of this study was to estimate trachoma prevalence in schoolchildren in Brazilian municipalities with a Human Development Index (HDI) below the national mean. METHODS: A cluster random sampling survey on trachoma prevalence was carried out. Brazilian municipalities with HDI below the national mean, within each of the 27 states, were stratified into three strata according to population size. In each stratum, schools were systematically selected to comprise a sample of 2400 schoolchildren, totaling 7200 per state. In each selected school, children enrolled from 1st to 4th grade were examined for trachoma. The simplified trachoma grading system was used. At a meeting held in each school, the study was explained to parents, and verbal consent sought. RESULTS: A total of 185,862 children were enrolled in the selected schools. Of these, 171,973 (92.5%) participated in the study. The overall prevalence of trachomatous inflammation - follicular was 5.0% (95% confidence interval 4.7-5.3%), varying from 1.5% to 9.0% among the states. Prevalence was significantly associated with the sampling stratum (being higher in small municipalities), the zone in which the school was located (higher in rural schools), and with age (higher among younger children). CONCLUSION: Trachoma is still a public health problem in Brazil, although at a low level of endemicity. As the country advances towards the elimination of blinding trachoma, this survey provides a baseline for evaluation of ongoing and future elimination interventions.

RESUMEN

PURPOSE: Trachoma, caused by the bacterium Chlamydia trachomatis, is a chronic, recurrent inflammatory disease that affects the cornea and conjunctiva. Trachoma is the leading infectious cause of avoidable blindness worldwide. Its prevalence is higher among individuals of low socioeconomic status, and trachoma is common in indigenous communities. The present study presents aspects of the epidemiological profile of trachoma in indigenous communities in Brazil. METHODS: We analyzed data from two databases collected during trachoma screening activities among the population of indigenous settlements in Brazil between 2000 and 2008. Trachoma cases were detected by ocular examination in accordance with the World Health Organization simplified trachoma grading system. RESULTS: According to the surveillance database, a total of 9582 individuals in six different states were examined. Among children aged 1-9 years, the prevalence of follicular trachomatous inflammation (TF) was 35.2%. In individuals aged ≥15 years, the prevalence of trachomatous trichiasis (TT) was 1.2% in individuals and the sex-specific prevalence was 0.8% in males and 1.6% in females (p = 0.02). In a survey of two states, 2301 indigenous schoolchildren were examined. In the age bracket 5-9 years, the prevalence of TF was 4.9 (95% confidence interval 3.8-6.0%). CONCLUSION: In Brazil, trachoma appears to be a serious public health problem in indigenous settlements, which should therefore be given priority in programs aimed at the elimination of trachoma in the country.

RESUMEN

OBJECTIVE: To estimate the prevalence and describe the distribution of trachoma among schoolchildren in Brazilian municipalities. METHODS: Cross-sectional study, using cluster sampling, of the schoolchildren population of the Brazilian municipalities with Human Development Index - Municipal lower than the national average. This trachoma prevalence survey was conducted by the Ministry of Health, in the period 2002-2007. There were 119,531 schoolchildren selected from 2,270 schools located in 1,156 municipalities. The selected schoolchildren underwent an external ocular examination, with a magnifying glass (2.5X), to detect clinical signs of trachoma according to the WHO criteria. The prevalence of trachoma, by state and national level, and their respective 95% confidence intervals were estimated. Chi-square and Chi-square for trends tests were used to compare categorical variables. RESULTS: There were 6,030 cases of trachoma detected, resulting in a prevalence of 5.0% (95%CI 4.5;5.4). There was no significant difference between the sexes. The prevalence of trachoma was 8.2% among children under 5 years of age, decreasing among higher age groups (p < 0.01). There was a significant difference in prevalence between urban and rural areas, 4.3% versus 6.2% respectively (p < 0.01). Cases were detected in 901 municipalities (77.7% of the sample), in all regions of the country. In 36.8% of the selected municipalities, the prevalence was higher than 5%. CONCLUSIONS: The study shows that trachoma is a significant public health problem in Brazil, contradicting the belief that the disease had been controlled in the country. The survey provides a baseline for evaluating planned interventions aimed at achieving the goal of global certification of elimination of trachoma as a cause of blindness in Brazil by 2020.

RESUMEN

PURPOSE: To estimate the trachoma prevalence in school children in Embu das Artes - SP, aiming the implementation of the disease epidemiological surveillance. METHODS: The city of Embu das Artes - SP, is 25 km far from the capital of the State. In the years of 2003-2004, a trachoma survey was conducted in a cluster sample of school children with the same methodology of the national trachoma student's survey of the Ministry of Health. Previously to the trachoma active search, activities of health education were performed in all schools. External ocular examinations were done in all students to detect trachoma according to the WHO criteria. All cases of trachoma were notified and their families were submitted to an external ocular examination. The cases were treated with 1% tetracycline ointment or systemic azithromycin. RESULTS: 2,374 students from nine sampled selected public schools were examined. The prevalence of follicular inflammatory trachoma (TF) was 3.1% (IC 95%: 2.4-3.9), varying from 0.5% to 4.2% in the examined schools. The prevalence for males was 3.2% and for females was 3.0%. The greater prevalence (8.6%) was found in 6 year-old children. CONCLUSION: The disease showed a mild behavior in this city, because no cases of intense inflammatory trachoma or cicatricial trachoma were detected. However, the prevalence was greater than the one found in the city of São Paulo. Epidemiological surveillance activities of trachoma must be continuous, mainly in places where the greater prevalence had been found.

RESUMEN

OBJETIVO: Estimar a prevalência do tracoma em escolares no município de Embu das Artes - SP, visando a implementação das ações de vigilância epidemiológica da doença. MÉTODOS: O município de Embu das Artes - SP dista 25 km da capital. Nos anos 2003-2004 foi realizado um inquérito por amostragem por conglomerados de escolares com a mesmo método do inquérito nacional de tracoma em escolares do Ministério da Saúde. Previamente aos trabalhos de busca ativa, foram realizadas atividades de educação em saúde em todas as escolas. Foi realizado exame ocular externo em todos os alunos para a detecção do tracoma, segundo os critérios da OMS. Todos os casos de tracoma foram tratados, notificados e seus familiares investigados. RESULTADOS: Foram examinados 2.374 alunos de nove escolas públicas sorteadas. A prevalência de tracoma inflamatório folicular (TF) foi 3,1% (IC 95%: 2,4% - 3,9%), variando de 0,5% a 4,2% nas escolas examinadas. Foi encontrada maior prevalência 8,6% em crianças com 6 anos de idade. CONCLUSÃO: A doença comportou-se de forma branda neste município, pois não foram detectados casos de tracoma intenso nem tracoma cicatricial. Todavia, a prevalência foi maior que a encontrada no município de São Paulo. As ações de vigilância epidemiológica do tracoma devem ser contínuas, principalmente nos locais onde foram encontradas as maiores prevalências.

RESUMEN

OBJECTIVE: Estimate cataract surgical rates (CSR) for Brazil and each federal unit in 2006 and 2007 based on the number of surgeries performed by the Unified Health System to help plan a comprehensive ophthalmology network in order to eliminate cataract blindness in compliance with the target set by the World Health Organization (WHO) of 3,000 cataract surgeries per million inhabitants per year. METHODS: This descriptive study calculates CSR by using the number of cataract surgeries carried out by the Brazilian Unified Health System for each federal unit and estimates the need for cataract surgery in Brazil for 2006-2007, with official population data provided by the Brazilian Institute of Geography and Statistics. The number of cataract surgeries was compared with the WHO target. RESULTS: To reach the WHO goal for eliminating age-related cataract blindness in Brazil, 560,312 cataract surgeries in 2006 and 568,006 surgeries in 2007 needed to be done. In 2006, 179,121 cataract surgeries were done by the Unified Health System, corresponding to a CSR of 959 per million population; in 2007, 223,317 were performed, with a CSR of 1,179. With the Brazilian Council of Ophthalmology estimation of 165,000 surgeries each year by the non-public services, the CSR for Brazil would be 1,842 for 2006 and 2,051 for 2007. The proportions needed to achieve the proposed target were 38.6% in 2006 and 31.6% in 2007. CONCLUSIONS: Human resources, technical expertise, and equipment are crucial to reach the WHO goal. Brazil has enough ophthalmologists but needs improved planning and infrastructure in order to eliminate the problem, aspects that require greater financial investment and stronger political commitment.

RESUMEN

PURPOSE: Trachoma, a blinding conjunctivitis, is the result of repeated infection with Chlamydia trachomatis. There are no recent data for the state of Roraima, Brazil, where it was thought that trachoma no longer existed. These data are derived from school children sampled in this state, with additional data collected from the contacts of children with trachoma. DESIGN: A population-based cross-sectional study with random sampling of students in grades 1 through 4 of all public schools within municipalities where the human development index was less than the national average in 2003. The sample was stratified according to population size. PARTICIPANTS: A sample size of 7200 was determined and a total of 6986 (93%) students were examined, along with an additional 2152 contacts. METHODS: All students were examined for trachoma according to World Health Organization criteria. Demographic data and contact information also was collected. The family and school contacts of students with trachoma then were located and examined. MAIN OUTCOME MEASURES: Prevalence and grade of trachoma, age, gender, race, and municipality location. RESULTS: The overall prevalence of trachoma was 4.5% (95% confidence interval [CI], 3.7%-5.3%), but there were municipalities within the state where the prevalence of inflammatory trachoma was more than 10%. The prevalence was greater in rural areas (4.9%; 95% CI, 3.7%-6.0%) compared with urban areas (3.9%; 95% CI, 2.9%-4.9%). Living in indigenous communities was associated with trachoma (odds ratio, 1.6; 95% CI, 0.9-2.6). An additional 2152 contacts were examined, and the overall trachoma prevalence was 9.3% (95% CI, 8.1-10.5). CONCLUSIONS: Trachoma continues to exist in Roraima, Brazil, where there are municipalities with a significant prevalence of disease. The indigenous population is highly mobile, crossing state and international borders, raising the possibility of trachoma in neighboring countries. Trachoma prevalence among the contacts of students with trachoma was higher than the school population, highlighting the importance of contact tracing.

OBJETIVO: Calcular las tasas de cirugía de cataratas (TCC) correspondientes al 2006 y el 2007 en todo el Brasil y en cada estado según la cantidad de intervenciones efectuadas en el Sistema Único de Salud, con el objeto de planificar una red integral de atención oftalmológica tendiente a eliminar la ceguera por cataratas, en cumplimiento de la meta fijada por la Organización Mundial de la Salud (OMS), de 3 000 intervenciones quirúrgicas de cataratas por millón de habitantes por año. MÉTODOS: En este estudio descriptivo se calculó la TCC según la cantidad de intervenciones quirúrgicas de cataratas llevadas a cabo en el Sistema Único de Salud del Brasil en cada estado, y se calculó la necesidad de intervenciones quirúrgicas de cataratas en el Brasil en el 2006 y el 2007 según los datos oficiales de la población proporcionados por el Instituto Brasileño de Geografía y Estadística. Se comparó la cantidad de intervenciones quirúrgicas de cataratas con la meta de la OMS. RESULTADOS: Para alcanzar la meta de la OMS de eliminar la ceguera producida por cataratas seniles en el Brasil, deberían haberse efectuado 560 312 intervenciones quirúrgicas de cataratas en el 2006, y 568006 en el 2007. En el 2006, se efectuaron 179 121 intervenciones quirúrgicas de cataratas en el Sistema Único de Salud, lo que representa una TCC de 959 por millón de habitantes; en el 2007, se realizaron 223317, con una TCC de 1179. Si estos datos se consideran junto con la estimación del Consejo Brasileño de Oftalmología de 165000 intervenciones quirúrgicas efectuadas cada año en los servicios no públicos, la TCC correspondiente al Brasil sería de 1842 para el 2006 y de 2 051 para el 2007. Las proporciones faltantes para lograr la meta propuesta fueron de 38,6 por ciento en el 2006 y de 31,6 por ciento en el 2007. CONCLUSIONES: Los recursos humanos, los conocimientos técnicos especializados y el equipo son esenciales para alcanzar la meta de la OMS. Brasil tiene suficientes oftalmólogos pero, para eliminar el problema, necesita una mejor planificación y más infraestructura, aspectos que requieren una mayor inversión financiera y un compromiso político más firme.

RESUMEN

OBJETIVO: Foi realizado um estudo transversal, por amostragem de escolares, frequentadores das escolas estaduais de Bauru, São Paulo, com o objetivo de detectar possíveis portadores de tracoma. MÉTODOS: Foram examinadas 1.749 crianças do ensino fundamental, de 6 a 14 anos, durante o ano de 2005. As escolas foram escolhidas por sorteio, de acordo com o número de estudantes e com a localização da escola dentro do setor da cidade (centro, região intermediária e periferia). O diagnóstico dos casos foi clínico, seguindo as normas da Organização Mundial de Saúde (OMS), confirmado laboratorialmente pelo método da imunofluorescência direta para detecção de Chlamydia trachomatis. RESULTADOS: A prevalência de tracoma inflamatório foi de 3,8 por cento, tendo sido diagnosticado tracoma folicular em 3,7 por cento e tracoma intenso em 0,06 por cento das crianças examinadas. As crianças com tracoma moravam principalmente na região intermediária e periférica da cidade, áreas onde o fornecimento de água pode ser descontínuo e o tratamento do esgoto pode estar ausente. Um programa de controle foi desenvolvido e os comunicantes foram diagnosticados e tratados. CONCLUSÃO: A prevalência de tracoma inflamatório em Bauru - Estado de São Paulo - é de 3,8 por cento. Além da oportunidade de reconhecer e tratar os portadores e contatantes, os autores realçam o fato positivo da mobilização da comunidade bauruense no sentido de prevenir a cegueira pelo tracoma.


PURPOSE: A survey was carried out with schoolchildren in Bauru, São Paulo State. The purpose of this study was to determine the prevalence of trachoma. METHODS: One thousand, seven hundred and forty-nine children from 6 to 14 years old were examined during the year of 2005. The schools were randomly chosen, according to the number of schoolchildren and the school region according to the local of the city (downtown, middle and periphery). The diagnosis was performed according to the World Health Organization (WHO) protocol and patients with clinical trachoma detection were submitted to laboratory confirmation by direct smear fluorescent antibodies cytology for Chlamydia trachomatis. RESULTS: Trachoma prevalence was 3.8 percent. Follicular trachoma was diagnosed in 3.7 percent of children, and intense trachoma in one child (0.06 percent). Children with trachoma were living mainly in the middle and peripheral region of the city, places with discontinuous water supply and absence of sewerage system in part of the residences. CONCLUSION: Trachoma prevalence in Bauru - São Paulo State - is 3.8 percent. The authors point out the survey results and also treated trachoma carriers. Other positive aspect of the survey was the community mobilization to prevent trachoma blindness.

RESUMEN

PURPOSE: To assess the ocular health practices within the neonatal units of the City of São Paulo, Brazil. METHODS: A questionnaire was sent to 36 neonatal units that performed 3000 or more deliveries during 2004. Data were collected on Credè's method of ophthalmia neonatorum prophylaxis, red reflex testing, retinopathy of prematurity (ROP) screening and treatment, and ophthalmic referral systems. RESULTS: All of the identified neonatal units completed the survey. Credè's method was used correctly in 31 (86%) units and the red reflex test was performed in 29 (81%) units. All units were aware of the risk factors for ROP, but the examination for its detection was executed on a routine basis in only 31 (86%) units and only 22 (61%) of the units were aware of the correct timing for the first examination for ROP. Treatment for ROP was done by the identifying hospital in 17 (55%) units and 14 (45%) hospitals transferred the neonate to an external service. After the patient's discharge, 30 (83%) neonatal units reported that they appropriately referred neonates for ophthalmic follow up. CONCLUSIONS: Prophylaxis against gonococcal conjunctivitis and the red reflex test need to be implemented more widely, tertiary referral systems need to be established in some services and the management of ROP should be improved. These recommendations may be achieved by designing and implementing guidelines around prevention and control activities to ensure that all avoidable ocular diseases are identified and managed appropriately within this vulnerable age group.
