Abstract Objective: This study aimed to assess attitudes, concerns, information and knowledge about vaccines among parents of preschool children attending kindergartens in a city in the interior of São Paulo, Brazil, using a self-administered questionnaire. Methods: Cross-sectional, questionnaire-based study of knowledge and attitudes regarding vaccination among parents of children aged up to 72 months from public and private schools, between 2018 and 2019. Results: Among the 2,528 questionnaires, 1,261 were answered and grouped by respondents’ educational level. According to information, 96.6% of the children were up to date with vaccines. The prevalence of vaccine hesitancy was 5.0%. The lower the educational level, the lower was the income, the larger the number of household members, and the greater the lack of knowledge about vaccines. The higher the educational level, the lower was the vaccine hesitancy, and the greater the dissatisfaction with the information received. Conclusions: Generally, parents consider vaccines to be important for preventing diseases and to be safe, with their benefits outweighing the risks. Positive comments were accompanied by doubts, concerns, hesitancy, and inconsistencies. The level of educational attainment makes a difference in the access to information, medical care provided by pediatricians, and the feeling of obligation to vaccinate. Parents have vaccinated and still intend to vaccinate their children, but ensuring adequate levels of vaccination coverage will be a post-pandemic challenge.

RESUMO Objetivo: Este estudo procurou avaliar atitudes, preocupações, informações e conhecimentos sobre vacinas por parte de responsáveis por crianças em idade pré-escolar que frequentam instituições de ensino infantil em um município do interior de São Paulo, Brasil, por meio de questionário autoaplicável. Métodos: Estudo transversal com o uso de questionário dirigido aos pais de crianças de até 72 meses, em escolas públicas e privadas, sobre conhecimentos e atitudes quanto à vacinação das crianças entre 2018 e 2019. Resultados: Entre 2.528 questionários entregues, 1.261 foram respondidos e agrupados conforme a escolaridade dos entrevistados. De acordo com as informações, 96,6% das crianças estavam com vacinas em dia. A prevalência de hesitação vacinal foi de 5,0%. Quanto menor a escolaridade, menor a renda, maior o número de habitantes na casa e maior o desconhecimento sobre vacinas. Quanto maior a escolaridade, menor hesitação e maior insatisfação com as informações recebidas. Conclusões: Em geral, os pais consideram as vacinas importantes para prevenir doenças, como proteção, e dizem que os benefícios superam os riscos. Manifestações positivas foram acompanhadas por dúvidas, preocupações, hesitações e inconsistências. O nível de escolaridade faz diferença no acesso a informações, no atendimento médico por pediatras e no sentimento de obrigatoriedade em vacinar. Os pais têm vacinado e ainda pretendem vacinar, mas garantir níveis de cobertura vacinal adequados será um desafio pós-pandemia.

ABSTRACT OBJECTIVE This study aimed to identify the treatment demands coming from primary health care units and, based on that, the demand for referrals to medical specialties in reference services. This study is justified by the scarcity of scientific literature on the subject. METHODS This is a cross-sectional study using secondary data on the treatments and referrals made by the primary health care units, throughout 2014, in a municipality of the State of São Paulo, Brazil. The total population treated in 2014 was considered, resulting in 411,177 treatments. RESULTS Out of all treatments performed, the percentage of referrals was of 4.42%, showing that 95,58% of the problems did not need to be referred to another service. A number of 8,897 referrals were made, to 6,850 users, who were mostly women (60.74%). The mean of referrals per patient was 1.3 (min. 1 and max. 8), and 1,604 patients (23.5%) were referred at least twice. CONCLUSIONS Primary health care services have been responsible for a large number of treatments, whereas the demand for referrals has decreased, suggesting that such services have established themselves as a gateway to the health system and achieved the expected solvability, although the waiting time for some specialties is very long.

RESUMO INTRODUÇÃO: A higiene nasal com soluções salinas tem sido indicada para aliviar a congestão, reduzir o espessamento do muco e manter a cavidade nasal limpa e úmida. OBJETIVO: Avaliar se as soluções salinas melhoram o fluxo inspiratório nasal entre crianças sadias. MÉTODO: Escolares com idades entre 8 e 11 anos foram submetidos a 6 procedimentos com soluções salinas em diferentes concentrações. O pico de fluxo inspiratório nasal foi medido antes e 30 minutos após cada procedimento. A análise estatística foi realizada por meio do teste t, análise de variância e teste de Tukey, considerando p < 0,05. RESULTADOS: Foram avaliadas 124 crianças em todas as etapas. Houve diferenças quanto à forma de uso de uma mesma concentração. Não houve diferença entre solução salina a 0,9% e solução salina a 3% por meio de seringa. CONCLUSÕES: A solução salina a 3% obteve maiores médias do pico de fluxo inspiratório nasal, porém não foi significativamente superior à solução salina a 0,9%. É importante oferecer diferentes opções aos pacientes.

ABSTRACT INTRODUCTION: Nasal hygiene with saline solutions has been shown to relieve congestion, reduce the thickening of the mucus and keep nasal cavity clean and moist. OBJECTIVE: Evaluating whether saline solutions improve nasal inspiratory flow among healthy children. METHODS: Students between 8 and 11 years of age underwent 6 procedures with saline solutions at different concentrations. The peak nasal inspiratory flow was measured before and 30 min after each procedure. Statistical analysis was performed by means of t test, analysis of variance, and Tukey's test, considering p < 0.05. RESULTS: We evaluated 124 children at all stages. There were differences on the way a same concentration was used. There was no difference between 0.9% saline solution and 3% saline solution by using a syringe. CONCLUSION: The 3% saline solution had higher averages of peak nasal inspiratory flow, but it was not significantly higher than the 0.9% saline solution. It is important to offer various options to patients.

OBJETIVO: Avaliar a prevalência de tracoma em escolares de Botucatu/SP-Brasil e a distribuição espacial dos casos. MÉTODOS: Foi realizado um estudo transversal, em crianças de 7-14 anos, que frequentavam as escolas do ensino fundamental de Botucatu/SP, em novembro/2005. O tamanho da amostra foi estimado em 2.092 crianças, considerando-se a prevalência histórica de 11,2%, aceitando-se erro de estimação de 10% e nível de confiança de 95%. A amostra foi probabilística, ponderada e acrescida de 20%, devido à possível ocorrência de perdas. Examinaram-se 2.692 crianças. O diagnóstico foi clínico, baseado na normatização da Organização Mundial da Saúde (OMS). Para avaliação dos dados espaciais, utilizou-se o programa CartaLinx (v1.2), sendo os setores de demanda escolar digitalizados de acordo com as divisões do planejamento da Secretaria de Educação. Os dados foram analisados estatisticamente, sendo a análise da estrutura espacial dos eventos calculadas usando o programa Geoda. RESULTADOS: A prevalência de tracoma nos escolares de Botucatu foi de 2,9%, tendo sido detectados casos de tracoma folicular. A análise exploratória espacial não permitiu rejeitar a hipótese nula de aleatoriedade (I= -0,45, p>0,05), não havendo setores de demanda significativos. A análise feita para os polígonos de Thiessen também mostrou que o padrão global foi aleatório (I= -0,07; p=0,49). Entretanto, os indicadores locais apontaram um agrupamento do tipo baixo-baixo para um polígono ao norte da área urbana. CONCLUSÃO: A prevalência de tracoma em escolares de Botucatu foi de 2,9%. A análise da distribuição espacial não revelou áreas de maior aglomeração de casos. Embora o padrão global da doença não reproduza as condições socioeconômicas da população, a prevalência mais baixa do tracoma foi encontrada em setores de menor vulnerabilidade social.

PURPOSE: To assess the prevalence of trachoma in schoolchildren of Botucatu/ SP-Brazil and its spatial distribution. METHODS: Cross-sectional study in children aged from 7 to 14 years, who attended elementary schools in Botucatu/SP in November/2005. The sample size was estimated in 2,092 children, considering the 11.2% historic prevalence of trachoma, accepting an estimation error of 10% and confidence level of 95%. The sample was random, weighted and increased by 20%, because of the possible occurrence of losses. The total number of children examined was 2,692. The diagnosis was clinical, based on WHO guidelines. For the evaluation of spatial data, the CartaLinx program (v1.2) was used, and the school demand sectors digitized according to the planning divisions of the Department of Education. The data were statistically analyzed, and the analysis of the spatial structure of events calculated using the Geode program. RESULTS: The prevalence of trachoma in schoolchildren of Botucatu was 2.9% and there were cases of follicular trachoma. The exploratory spatial analysis failed to reject the null hypothesis of randomness (R= -0.45, p>0.05), with no significant demand sectors. The analysis for the Thiessen polygons also showed that the overall pattern was random (I= -0.07, p=0.49). However, local indicators pointed to a group of low-low type for a polygon to the north of the urban area. CONCLUSION: The prevalence of trachoma in schoolchildren in Botucatu was 2.9%. The analysis of the spatial distribution did not reveal areas of greater clustering of cases. Although the overall pattern of the disease does not reproduce the socio-economic conditions of the population, the lower prevalence of trachoma was found in areas of lower social vulnerability.

Com o objetivo de estudar a soroprevalência de vírus linfotrópico de células T humanas I/II (HTLV-I/II), vírus da imunodeficiência humana, sífilis e toxoplasmose, em gestantes atendidas em unidade básicas de saúde do município de Botucatu - São Paulo - Brasil, bem como os fatores de risco para a infecção pelo HTLV -I/II, foram realizados inquérito sorológico e avaliação dos resultados de exames solicitados na rotina do prénatal. Em 913 gestantes, a soroprevalência de HTLV- I e de HTLV- II foi de 0,1%. Sífilis, toxoplasmose e infecção pelo HIV foram encontradas. Nenhum dos fatores de risco pesquisados mostrou-se seguro para identificar gestantes com infecção pelo HTLV- I/II. A comparação da proporção de gestantes infectadas e de doadores de sangue da região sudeste do Brasil com testes reagentes para HTLV- I/II não mostrou diferença estatística.

In order to asses the soroprevalence of HTLV- I/II, HIV, siphylis, and toxoplasmosis infection among pregnant women seen at Basic Health Units in the municipality of Botucatu - São Paulo - Brazil, and risk factors for HTLV- I/II infection, sorologic surveys were carried out and results of sorologic surveys carried in pregnance routine evaluation were assessed. Seroprevalence was 0.1% (1 in 913) for both HTLV-I and HTLV-II. Seroprevalence was 0.1% (1 in 913) for both HTLV-I and HTLV-II. Siphylis, toxoplasmosis and HIV were identified. None of the factors or characteristics risks was found to be useful to identify those prenant women HTLV-II infected. Infection among pregnant women and southeast brazilian blood donnors were not diferent in statistical evaluation.
