RESUMO
BACKGROUND: Attention to prenatal care and child delivery is important for the health of women and children, but in the Amazon these indicators tend to be historically unfavorable, in part by geographical and political isolation. In 2003 both Brazilian and Peru governments have finished paving an international road connecting remotes areas in the Brazilian Amazon to the Pacific coast in Peru. METHODS: The situation of prenatal care and child delivery with mothers of children under 5 years old living in the urban area of Assis Brasil, Acre was assessed in two cross-sectional studies performed in 2003 and 2011, corresponding to the period before and after the Pacific highway construction. RESULTS: In 2003, most mothers were of black/Afro-American ethnicity, or "pardos" (the offspring of a Caucasian with a African descendant) (77.69 %), had more than 4 years of schooling (73.40 %) and had a mean age of 22.18 years. In 2011, the number of as a migration of indigenous women increased from 0 to 14.40 % of the respondents, because of migration from communities along the rivers to urban areas, with no other significant changes in maternal characteristics. No significant improvement in childbirth assistance was noticed between 1997 and 2011; only the percentage of in-hospital vaginal deliveries performed by doctors increased from 17.89 to 66.26 % (p <0.001) during this period. Access to prenatal care was associated with white ethnicity in 2003, and higher socioeconomic level and white ethnicity in 2011, while the higher number of prenatal visits was associated with higher maternal education and higher socioeconomic levels in 2011. Vaginal child delivery at a hospital facility was associated with maternal age in 2003, and year of birth, being of white ethnicity and higher level of education in 2011. CONCLUSIONS: The indicators of prenatal care and child delivery were below the national average, showing that geographical isolation still affects women's health care in the Amazon, despite the construction of the highway and governmental health protocols adopted during this period.

The training of future physicians should be concurrent with the development of different skills and attitudes. This warrants the need to regularly provide students with opportunities for self-development throughout their academic career. This approach was exemplified in a medical school in the Brazilian Amazon, where students were allowed to play the role of high school teachers. As part of this exercise, they conducted reinforcement classes for high school students to increase the number of university admissions. The medical students were solely responsible for organizing and implementing this project, giving them the opportunity to develop teaching and leadership skills, enhance their understanding of communication and administration and contribute toward the society.

INTRODUCTION: Vaccines are very important to reduce morbidity and mortality by preventable infectious diseases, especially during childhood. Optimal coverage is not always achieved, for several reasons. Here we assessed vaccine coverage for the first 12 months of age in children between 12 and 59 months old, residing in the urban area of a small Amazonian city, and factors associated with incomplete vaccination. METHODS: A census was performed in the urban area of Assis Brasil, in the Brazilian Amazon, in January 2010, with mothers of 282 children aged 12 to 59 months old, using structured interviews and data from vaccination cards. Mixed logistic regression was used to determine factors associated with incomplete vaccination schemes. RESULTS: Only 82.6% of all children had a completed the basic vaccine scheme for the first year of life. Vaccine coverage ranged from 52.7% coverage (oral rotavirus vaccine) to 99.7% coverage (for Bacille Calmette-Guérin). The major deficiencies occurred in doses administered after the first six months of life. Incomplete vaccination was associated with not having enough income to buy a house (aOR = 2.12, 95% CI 1.06-4.21), low maternal schooling (aOR = 2.60, 95% CI 1.28 - 5.29) , and time of residence of the child in the urban area of the city (aOR = 0.73, 95% CI 0.55 - 0.95). CONCLUSIONS: This study showed that vaccine coverage in the first twelve months of life in Assis Brasil is similar to other areas in the Amazon and it is below the coverage postulated by the Brazilian Ministry of Health. Low vaccine coverage was associated with socioeconomic inequities that still prevail in the Brazilian Amazon. Short and long-term strategies must be taken to update child vaccines and increase vaccine coverage in the Amazon.

Despite the process of nutritional transition in Brazil, in some places, such as the Amazon region, stunting is still an important public health problem. We identified the prevalence and factors associated with stunting in children under five years old residing in the urban area of Assis Brasil. A survey was conducted in which a questionnaire on socioeconomic, maternal and children's conditions was applied, and height or length was measured. The children with height for age index below -2 Z-scores were considered stunted, according to the criteria by the World Health Organization. Four hundred and twenty-eight children were evaluated. Of these, 62 were stunted. Factors associated with stunting, according to adjusted models, were: the presence of open sewer, the wealth index for households, the receipt of governmental financial aid and the mother's height, age and education. Therefore, it was observed that family and the mother's characteristics as well as environmental and socioeconomic factors were closely related to the occurrence of stunting in the population studied, and such nutritional disturbance is still a health problem in the Brazilian Amazon.

Introduction. Children under 5 years of age are more susceptible to developing morbidities such as diarrhea, respiratory infections, anemia, and malnutrition. The objective of the study is to evaluate the prevalence of reported morbidities in this age group in the city of Iñapari (Peru) and the access to health services in this municipality. Methods. Data collection using interviews that assessed socioeconomic and demographic conditions, child morbidity, and access to health services was performed in 2011. Statistical analysis was performed using SPSS 13.0. Results. Regarding morbidities that occurred during lifetime, 39.8% reported previous anemia and intestinal parasite infection. About 53.7% of the children reported any type of morbidities in the last 15 days before interview, being most frequent respiratory symptoms (38.9%), diarrhea (23,4%), and fever (23,1%). Only 63.1% of those reporting recent morbidities sought health care. These morbidities were associated with precarious sanitation and lack of infrastructure, the presence of other comorbidities, and poor access to health services. Conclusion. The main referred morbidities in Amazonian Peruvian children were diarrhea, respiratory symptoms, anemia, and vomiting. Incentives and improvements in the health and sanitation conditions would be important measures to improve the quality of life of the Amazonian child population.
RESUMO
This study aimed to evaluate the prevalence of serum IgG dengue in children in an Amazonian population, to assess the seroconversion rate in 12 months, and to estimate how many seropositive children had a prior clinical diagnosis of dengue. We conducted a population-based study between 2010 and 2011, with children aged 6 months to 12 years that were living in the urban area of a small town in the Brazilian Amazon. The prevalence of IgG antibodies against dengue antigens was determined by indirect ELISA technique, and seronegative children were reexamined after 12 months to determine seroconversion rates. Results showed seroprevalence of IgG antibodies against dengue type of 2.9%, with no significant association between age, race, and sex. In seropositive children, only 8.4% had received a clinical diagnosis of dengue, and the ratio of clinically diagnosed cases and subclinical cases was 1 : 11. The seroconversion rate between 2010 and 2011 was 1.4% (CI 3.8% to 35.1%). The seroprevalence of dengue in this pediatric population was low, and the vast majority of cases were not clinically detected, suggesting a difficulty in making the clinical diagnosis in children and a high frequency of asymptomatic infections.
RESUMO
Este estudo avaliou as mudanças ambientais da paisagem urbana de um município com alta incidência de malária na Amazônia brasileira (Mâncio Lima, Acre) e sua relação com a doença, com o objetivo de prover evidências de que a transmissão do Plasmódio é causada pelo modo como os seres humanos interagem com o meio-ambiente. Foram efetuados três estudos populacionais consecutivos, entre 2012 e 2013, com 1260 indivíduos, com identificação do plasmódio por microscopia e técnicas moleculares. Casos de malária foram analisados mediante um questionário clinico. O estudo entomológico envolveu 8 inquéritos transversais com coleta de formas imaturas em 90 corpos dágua, bem como avaliação espacial desses dados. Os resultados mostraram que a transmissão de malária na área deveu-se em grande parte a criação de tanques de piscicultura, que elevaram em cerca de 10 vezes a produtividade de imaturos de Anopheles darlingi, e à grande mobilidade da população, que se desloca para áreas de maior transmissão (como área ribeirinha e rural) e retorna infectada para a área urbana. Foram identificados casos de portadores assintomáticos do Plasmódio, embora em pequena quantidade. Os fatores associados a ausência de sintomas (infecção assintomática) foram o sexo e o tempo da última malária. Em pacientes sintomáticos, a frequência dos sintomas se relacionou com idade, número de malárias previas e parasitemia. A concentração geográfica dos casos deveu-se em parte a características socioeconômicas agregadas no espaço, em conjunto com fatores ambientais como presença do vetor, visto que o uso infrequente de mosquiteiro associouse com a incidência maior de malária.
This study evaluated the environmental changes of the urban landscape of a municipality with a high incidence of malaria in the Brazilian Amazon (Mâncio Lima, Acre) and its relation with the disease, in order to provide evidence that the transmission of Plasmodium is caused by the way humans interact with the environment. Three consecutive population studies were carried out between 2012 and 2013, with 1260 individuals, with plasmodium identification by microscopy and molecular techniques. Malaria cases were analyzed using a clinical questionnaire. The entomological study involved 8 cross-sectional surveys with collection of immature forms in 90 bodies of water, as well as spatial evaluation of these data. The results showed that the transmission of malaria in the area was largely due to the creation of fish tanks, which increased the immature productivity of Anopheles darlingi by around 10 times, and the great mobility of the population, which moves to areas of greater transmission (as riverside and rural area) and returns infected to the urban area. Cases of asymptomatic Plasmodium carriers have been identified, albeit in small numbers. Factors associated with absence of symptoms (asymptomatic infection) were the sex and time of the last malaria. In symptomatic patients, the frequency of symptoms was related to age, number of previous malaria and parasitemia. The geographic concentration of the cases was due in part to aggregate socioeconomic characteristics in space, together with environmental factors such as vector presence, since the infrequent use of mosquito nets was associated with a higher incidence of malaria.

Food and nutrition security is the regular and permanent access to quality food in sufficient quantity. The aim of this study was to estimate the prevalence and factors associated with food insecurity in households with children under five in the Amazon frontier Brazil - Peru. The study was conducted in 352 households in Assis Brasil (Brazil) and 89 households Iñapari (Peru), finding a prevalence of food insecurity of 40.6 % and 38.2 % , respectively ( p = 0.856 ) . In Assis Brasil, having domicile with wood floors or land increased by 2.47 times the odds of food insecurity compared to cement floors, ceramic or quarry tiles . Belonging to the poorest tertile increased the chance of food insecurity in 6.04 times ( p < 0.001 ), and the increment of each new resident increased by 37 % the chance of food insecurity in the household . In Iñapari, only living in house made of wood or with a wood floor was associated with food insecurity, showing that income is still the main factor associated with food insecurity in the Amazonian borders.
A segurança alimentar e nutricional consiste na realização do direito de todos ao acesso regular e permanente a alimentos de qualidade, em quantidade suficiente, sem comprometer o acesso a outras necessidades essenciais, tendo como base práticas alimentares promotoras de saúde que respeitem a diversidade cultural e que sejam ambiental, cultural, econômica e socialmente sustentáveis. O objetivo deste estudo foi estimar a prevalência e os fatores associados a insegurança alimentar em famílias com crianças menores de cinco anos na fronteira amazônica Brasil - Peru. O estudo foi realizado nos municípios de Assis Brasil (Brasil) e Iñapari (Peru) localizados na tríplice fronteira formada por Brasil, Bolívia e Peru. Dos 441 domicílios com crianças menores de 5 anos identificados, 352 (79,82%) localizavam-se em Assis Brasil, e os demais em Iñapari. As prevalências de insegurança alimentar nos municípios são semelhantes. Assis Brasil apresentou 40,6% e Iñapari 38,2% (p=0,856). Em Assis Brasil, ter domicilio com piso de madeira ou terra aumentou em 2,47 vezes a chance de insegurança alimentar comparado a piso de cimento, tijolo, cerâmica ou lajota. Pertencer ao tercil mais pobre aumentou a chance da insegurança alimentar em 6,04 vezes (p < 0,001), e o incremento de cada novo morador aumentou 37% a chance de insegurança alimentar no domicílio. Este estudo mostra que na região amazônica a renda ainda é o principal fator associado a insegurança alimentar.

Introduction: Iñapari is a town located in Peru, on the border of Brazil, between the Amazonian states of Acre and Amazonas. The local Peruvian children under five years of age present moderate anemia while the percentage of chronic child malnutrition is a major public health problem in the country as a whole. Goals: The purpose of this study was to identify the prevalence of major childhood morbidities caused by anemia, malnutrition, intestinal parasites, toxocariasis, and hepatitis A, and identify connections with the socioeconomic and environmental conditions found in Iñapari. Methods: Interviews with questionnaires; anthropometric measurements, collection of feces and venous blood samples. Results: A 20% prevalence of anemia and 8.5% prevalence of chronic malnutrition (height for age deficiency) was found. A pathogenic intestinal parasite was noted in 24.5% of the samples, where Giardia intestinalis (14.7%) was the most frequent. The seroprevalence of toxocariasis was 33.8% and hepatitis A was 21.2%. Conclusion: There is a connection between the results found and the poor living and sanitary conditions of the population. The low income noted is also linked to the malnutrition and anemia detected

Resumo Apesar do processo de transição nutricional no Brasil, em alguns lugares, como a região amazônica, o nanismo ainda é um importante problema de saúde pública. Identificou-se a prevalência e fatores associados ao déficit de crescimento em crianças menores de cinco anos de idade residentes na área urbana de Assis Brasil. Um inquérito foi realizado utilizando instrumento semiestruturado sobre características socioeconômicas, maternas e das crianças, e foram aferidas medidas antropométricas. As crianças com índice de estatura para idade inferior a -2 escores-Z foram consideradas com déficit de crescimento, de acordo com os critérios da Organização Mundial da Saúde. Quatrocentos e vinte e oito crianças foram avaliadas. Destas, 62 apresentaram déficit de crescimento. Os fatores associados à baixa estatura, de acordo com modelos ajustados, foram: presença de esgoto a céu aberto, índice de riqueza para as famílias, recebimento de ajuda financeira governamental, altura materna, idade e escolaridade maternas. Portanto, observou-se que as características familiares e da mãe, bem como fatores ambientais e socioeconômicos estavam intimamente relacionados com a ocorrência de déficit de crescimento na população estudada, e que a desnutrição ainda é um problema de saúde na Amazônia brasileira.

Este estudo descreve o perfil epidemiológico da leishmaniose tegumentar americana (LTA) emAssis Brasil-AC entre 2003 e 2010. As fichas de notificação dos casos confirmados de LTA do município foram revisadas e as frequências foram comparadas utilizando-se o Teste Exato de Fisher ou Qui-quadrado. Foram notificados 579 casos de LTA, com um coeficiente de detecção de 191 e 82 casos por 10.000 habitantes em 2003 e 2010, respectivamente. Os casos ocorreram mais em homens (63,0por cento), em moradores da zona rural (72,3por cento) e com ocupação relacionada ao meio ambiente (52,5por cento). Cerca de 81por cento dos casos era de moradores de Assis Brasil, 3,6por cento de outros municípios acreanos, 10,4por cento do Peru, 1,7por cento da Bolívia e 3,8por cento sem informação. Houve predomínio da forma cutânea (53,5por cento), com poucas recidivas (1,7por cento). O diagnóstico foi confirmadopreferencialmente com o teste intradérmico, sendo o diagnóstico microscópico direto pouco usado (17,4por cento). Inadequações no tratamento prescrito ocorreram quanto à dose (inadequada em 56,3por centodos casos mucosos) e ao tempo de tratamento (3,7por cento dos casos com tempo insuficiente). Existe aparente deficiência de recursos humanos para executar os testes diagnósticos necessários e fazer o preenchimento da ficha de notificação, portanto melhorias na rede de atenção básica são necessárias para o controle eficiente desta endemia.

A hanseníase é considerada um problema de saúde pública nos países em desenvolvimento. No período de 2001 a 2007, o Acre foi o 8o Estado com os maiores coeficientes de prevalência e incidência de hanseníase em todo o Brasil. Este é um estudo retrospectivo que utilizou os dados das fichas de notificação de casos de hanseníase do Sistema de Informação de Agravos de Notificação do município de Assis Brasil, Acre, entre 2003 e 2010. Os dados foram digitados e analisados no programa SPSS, sendo que médias e proporções foram comparadas com o Teste de Anova e o Teste do Qui-Quadrado. Foram notificados 25 casos novos, com coeficiente de detecção de 98,7/100.000 habitantes em 2010, sendo 56% casos índices e 44% contatos; oito (32%) casos de hanseníase paucibacilar e 17 (68%) de hanseníase multibacilar. Predominou a forma dimorfa (52%), seguido da forma tuberculóide (32%) e forma virchowiana (16%). A bacilos-copia foi negativa em 75% dos testes. Nove pacientes foram considerados curados no tempo preconizado, um paciente necessitou de maior tempo de tratamento, oito pacientes ainda estavam em tratamento e seis casos ti-veram evolução desconhecida. A alta frequência de ca-sos de hanseníase multibacilar reforça a ideia da demora no diagnóstico e da dificuldade em detectar formas mais leves da doença, contribuindo para manter a transmis-são, necessitando de maior ação do sistema de saúde.
Leprosy is a public health problem in the developing world. Between 2001 and 2007, Acre state presented the 8th highest incidence and prevalence coefficients in the whole country. This is a retrospective study that used the notification data from the local health system, between 2003 and 2010. Data was analyzed in SPSS; av-erages and proportions were compared using Anova and Chi-square test. There were 25 new cases notified, with a new case detection coefficient of 98,7/100.000 inhabitants in 2010, being 56% index cases, 44% con-tacts; eight (32%) paucibacillary cases and 17 (68%) multibacillary cases. The predominant clinical form was dimorphous (52%), followed by tuberculoid (32%) and virchow ́s forms (16%). The baciloscopy was negative in 75% of cases. Nine patients were considered cured in the allotted time, one patient needed longer treatment time, eight patients were still under treatment and six patients had unknown follow-up. The high frequency of multibacillary cases reinforces the idea that the diag-nosis is taking long to be performed and it is difficult to detect mild forms of the disease, contributing for main-taining the transmission, therefore a more effective ac-tion must be taken by the health system.
