Abstract Sugammadex is a distinctive neuromuscular reversal drug that acts by encapsulating the neuromuscular relaxant molecule and dislodging it from its site of action. Sugammadex has been approved for pediatric patients over 2 years of age. Although arrhythmias have been reported, there is no report of adverse effects in healthy children, such as severe bradycardia requiring intervention. We report two cases of severe bradycardia immediately after the administration of sugammadex in healthy children. Our aim is to alert to the occurrence of one of the most severe adverse effects of sugammadex, in the healthy pediatric population as well.

SUMMARY OBJECTIVE: This study aimed to assess the perinatal outcomes of pregnancies with a prenatal diagnosis of congenital cystic adenomatoid malformation. METHODS: We conducted a retrospective cohort study based on information contained in the medical records of pregnant women whose fetuses had been prenatally diagnosed with congenital cystic adenomatoid malformation by ultrasonography. RESULTS: Sample analysis was based on 21 singleton pregnancies with confirmed isolated fetal congenital cystic adenomatoid malformations. The mean maternal±standard deviation age was 28±7.7 years. Types I, II, and III congenital cystic adenomatoid malformation were detected in 19% (4/21), 52.4% (11/21), and 28.6% (6/21), respectively. All fetuses presented with unilateral congenital cystic adenomatoid malformation (21/21) without associated anomalies, and 52.3% (11/21) were in the right lung. In total, 33.3% (7/21) of fetuses presented a “congenital cystic adenomatoid malformation volume ratio” >1.6 and were managed with maternal betamethasone administration. The mean gestational age at the time of steroid administration was 28.5±0.9 weeks, with a reduction in the lesion dimensions of 9.5% (2/21) (Types I and III of congenital cystic adenomatoid malformation). The mean gestational age at delivery was 38.7±2.4 weeks, and a cesarean section was performed in 76.2% (16/21) cases. Postsurgical resection was necessary for 23.8% (5/21) of the patients, and 4.7% (1/21) of them died because of respiratory complications after surgery. Pulmonary hypoplasia occurred in 9.5% (2/21) of the patients, and 4.7% (1/21) of them died because of respiratory insufficiency. The survival rate was 90.5% (19/21), and 57.2% (12/21) remained asymptomatic. CONCLUSION: Despite the isolated prenatal diagnosis of congenital cystic adenomatoid malformation, which showed good survival, congenital cystic adenomatoid malformation is associated with significant perinatal morbidity. Maternal betamethasone administration did not significantly reduce fetal lung lesion dimensions.

ABSTRACT Science communication has emerged as a new field over the last 50 years, and its progress has been marked by a rise in jobs, training courses, research, associations, conferences and publications. This paper describes science communication internationally and the trends and challenges it faces, before looking at the national level. We have documented science communication activities in Brazil, the training courses, research, financial support and associations/societies. By analyzing the publication of papers, dissertations and theses we have tracked the growth of this field, and compared the level of activity in Brazil with other countries. Brazil has boosted its national research publications since 2002, with a bigger contribution from postgraduate programs in education and communication, but compared to its national research activity Brazil has only a small international presence in science communication. The language barrier, the tradition of publishing in national journals and the solid roots in education are some of the reasons for that. Brazil could improve its international participation, first by considering collaborations within Latin America. International publication is dominated by the USA and the UK. There is a need to take science communication to the next level by developing more sophisticated tools for conceptualizing and analyzing science communication, and Brazil can be part of that.

To make this evaluation, some techniques will be used, such as Data Envelopment Analysis, ordinal logit and revealed preference. By using the DEA technique, the efficiency will be ranked between high, medium and low, and this ranking will be the dependent variable of the ordinal logit model, and the independent variables of this model are derived from the utilities from the revealed preference model and the maxdiff model that evaluated some features that were not declared on the preference model..

Resumo Este estudo analisou a relação entre a pluviosidade, temperatura e ocorrência de casos de dengue. Estudo ecológico, realizado no município de São Luís (MA), com os casos de dengue autóctone notificados no período de 2003 a 2010, e os dados mensais de pluviosidade e temperatura. A incidência mensal de casos de dengue foi calculada por ano/100.000hab. Para a identificação da influência das variáveis climáticas e casos de dengue foram ajustados diferentes modelos de defasagem distribuída, considerando a distribuição binomial negativa. A seleção dos modelos foi baseada no critério AIC (Akaike Information Criterion). Foram notificados 13.444 casos de dengue entre 2003 e 2010, com picos em 2005, 2007 e 2010. A correlação dos índices pluviométricos com a ocorrência da dengue mostrou aumento de casos nos primeiros meses subsequente aos chuvosos. Houve ocorrência de casos de dengue em todo o período estudado, caracterizando o município como endêmico-epidêmico. Além disso, a relação entre casos de dengue e quantidade de chuva foi significativa com defasagem de três meses. Estes resultados são úteis para o desenvolvimento futuro de políticas de saúde para controle e prevenção da dengue.

Abstract This study analyzed the relationship between rainfall, temperature and occurrence of dengue cases. Ecological study performed with autochthonous dengue cases reported during 2003 to 2010 in São Luís, Maranhão. Data of rainfall and temperature were collected monthly. The monthly incidence of dengue cases was calculated by year/100,000 inhabitants. In order to identify the influence of climate variables and dengue cases different distributed lag models using negative binomial distribution were considered. Model selection was based on the lowest AIC (Akaike Information Criterion). Thirteen thousand, four hundred forty-four cases of dengue between 2003 and 2010 were reported, with peaks in 2005, 2007 and 2010. The correlation between rainfall and the occurrence of dengue cases showed increase in the first months after the rainy months. Occurrence of dengue cases was observed during all the period of study. Only rainfall-lag per three months showed a positive association with the number of cases dengue. Thus, this municipality is considered as an endemic and epidemic site. In addition, the relation between rainfall and dengue cases was significant with a lag of three months. These results should be useful to the future development of politics healthy for dengue prevention and control.

A Aids é um problema de saúde pública e a Leishmaniose visceral (LV) a forma mais frequente de coinfecção. O objetivo é descrever aspectos epidemiológicos dos indivíduos HIV positivo e investigar a ocorrência de coinfecção HIV-Leishmania. Trata-se de estudo descritivo realizado com 287 indivíduos HIV positivo atendidos no Centro de Referência para DST/Aids em São Luís (MA). Foi realizado teste de Intradermorreação de Montenegro, aspirado de medula óssea para detecção da infecção por Leishmania sp e aplicado um questionário na coleta dos dados epidemiológicos. O teste qui-quadrado foi usado para diferenças entre gênero, com p < 0,05 de significância. Houve significância estatística entre os homens relacionados ao uso de fossa séptica e renda até dois salários. Quanto à exposição, foi predominante a categoria heterossexual para ambos os sexos, sendo observado um aumento entre as mulheres. Entre os indivíduos HIV positivo 4,2% apresentavam sintomatologia sugestiva de LV sendo identificadas formas amastigotas para Leishmania sp no aspirado de medula óssea. O perfil dos indivíduos HIV positivo não diferiu de outras regiões do Brasil com predomínio de jovens em idade produtiva, sendo constatada uma sobreposição das áreas de transmissão para a coinfecção HIV-LV.

AIDS is a public health problem and visceral leishmaniasis (VL) is the most frequent co-infection. This study seeks to describe the epidemiological aspects of HIV-positive individuals and to investigate the occurrence of HIV-Leishmania co-infection. It is a descriptive study with 287 HIV=positive individuals assisted at the reference center for HIV/AIDS in São Luís, MA. Montenegro's intradermal reaction and bone marrow aspiration were performed for detecting the Leishmania sp. infection. Epidemiological data were collected by means of a questionnaire. The chi-square test was used for gender differences, with p < 0.05 of statistical significance level. There was statistical significance among men regarding the use of septic tanks, and income of up to two salaries. Regarding exposure, heterosexual orientation was the most frequent category for both genders, and we observed an increase in this category among women. Among HIV-positive individuals, 4.2% had suggestive symptoms of VL with identification of Leishmania amastigotes in bone marrow aspirate (myelogram). The profile of HIV-positive individuals did not differ from what is commonly found in Brazil, with predominance of young people of productive age. Furthermore, a superposition of the transmission areas for HIV-LV co-infection was found.

Epidemiological studies have demonstrated that the variability of the clinical response to infection caused by Mycobacterium leprae is associated with host genetic factors. The present study investigated the frequency of human leukocyte antigen (HLA) class II (DRB1) alleles in patients with leprosy from São Luís, Maranhão, Brazil. A case-control study was performed in 85 individuals with leprosy and 85 healthy subjects. All samples were analysed via polymerase chain reaction-sequence specific oligonucleotide probes. The HLA-DRB1*16 allele showed a higher frequency in the group with leprosy [(9.41% vs. 4.12%) odds ratio (OR) = 2.41 95% confidence interval (CI) (0.96-6.08) p = 0.05], whereas the HLA-DRB1*11 allele was less frequent in the group with leprosy [(6.47% vs. 11.76%) OR = 0.51 95% CI (0.23-1.12) p = 0.09]. The frequency of HLA-DRB1* alleles between the control group and leprosy patient subgroups presenting different forms of the disease showed that the HLA-DRB1*16 (16.13% vs. 8.24%, OR = 4.10, CI = 1.27-13.27, p = 0.010) and HLA-DRB1*14 (5% vs. 3.53%, OR = 4.63, CI = 1.00-21.08, p = 0.032) alleles were significantly more frequent in patients with different clinical subtypes of leprosy. The sample size was a limitation in this study. Nevertheless, the results demonstrated the existence of a genetic susceptibility associated with the clinical forms of leprosy. The low frequency of the HLA-DRB1*11 allele should be further studied to investigate the possible protective effect of this allele.

INTRODUÇÃO: A hanseníase é uma doença infecto-contagiosa causada pelo Mycobacterium leprae. Este estudo descreve os aspectos epidemiológicos, clínicos e operacionais de portadores de hanseníase. MÉTODOS: Estudo transversal, realizado no município de São Luis, MA. RESULTADOS: Foram analisados 85 casos, sendo 51,7%, do sexo masculino e cor parda (60%). As mulheres tinham entre 35 a 49 anos de idade (54,8%) e os homens entre 20 a 34 (57,6%). A forma virchowiana foi mais frequente (42,3%), a classe operacional a multibacilar (72,9%) e baciloscopia positiva em 42,3%. Houve ocorrência de reação em 43,5%, e ausência da cicatriz da Bacillus Calmette-Guérin (BCG) em 83,5%. Hanseníase na família foi referida por 44,7%. As casas eram de alvenaria (96,4%), tinham mais de 3 cômodos (72,6%), dormindo duas pessoas por cômodo (65,1%). Quanto aos anos de estudo, 41,4% de mulheres e 34% de homens tinham de um a três anos. A faixa etária entre 35 e 49 anos foi a mais avaliada com Grau 0 de incapacidade, no início do tratamento (64,5%) e no final, foi entre 20 e 34 e destes 29,9% tinham Grau 0, 30,7% Grau 1 e 11,5% Grau 2. CONCLUSÕES: A frequência das formas multibacilares e casos em familiares indicam diagnósticos tardios, reforçando a importância do diagnóstico precoce e tratamento adequado, para a redução do aparecimento de incapacidades.

INTRODUCTION: Leprosy is an infectious disease caused by Mycobacterium leprae. The aim of this study was to describe the epidemiological, clinical, and operational aspects of leprosy carriers. METHODS: A cross-sectional study leprosy patients assisted in São Luis, MA, was performed. RESULTS: Of the 85 cases analyzed, 51.7% were male participants, and 60% were brown. Concerning the age, 54.8% of women were between 35 and 49 years, and 57.6% of men were between 20 and 34 years. Lepromatous leprosy was found in 42.3% of cases, and the multibacillary form was found in 72.9%. The skin smear was positive in 42.3%. The occurrence of reaction was found in 43.5% of cases, and 83.5% had no Bacillus Calmette-Guérin scar. Leprosy in the family was reported by 44.7% of the patients. Most of the individuals (96.4%) lived in houses made of brick with more than three rooms (72.6%) and two persons per room (65.1%). Concerning the level of education, 41.4% of women and 34.1% of men had more than one to three years of education. The most evaluated age group in the beginning of the treatment was that of 35 to 49 years with a Grade 0 incapability (64.5%), and that in the end was the age group of 20 to 34 (29.9%) with Grade 0, 30.7% Grade 1, and 11.5% Grade 2. CONCLUSIONS: The frequency of multibacillary forms found in this study and the cases in family members point out delayed diagnoses. Thus, early diagnosis and appropriate treatment are important in decreasing the outcome of disabilities.

Dengue and dengue hemorrhagic fever, vector-borne diseases transmitted by the mosquito Aedes aegypti, are presently important public health problems in Brazil. As the strategy for disease control is based on vector control through the use of insecticides, the development of resistance is a threat to programs efficacy. The objective of this study was to compare the Aedes aegypti susceptibility in nine vector populations from the state of São Paulo and seven from Northeast region of Brazil, since there was a difference on group of insecticide used between the areas. Bioassays with larvae and adult were performed according to the World Health Organization methods.The results showed higher resistance levels to organophosphates group in populations from the Northeast region where this group was used for both larvae and adult control than in São Paulo where organophosphates were used for larvae and pyretroids for adult control. Resistance to pyretroids in adults was widespread in São Paulo after ten years of use of cypermethrin while in vector populations from the Northeast region it was punctual. The difference in resistance profile between the areas is in accordance to the group of insecticide used.

O texto faz uma reflexão sobre o uso da imprensa na sala de aula e sua relação com o processo de aprendizagem. Questiona a excessiva inserção de fragmentos do discurso jornalístico nos livros didáticos em detrimento de outros gêneros. Discute a qualidade da narrativa jornalística e os riscos que ela encerra se não houver uma leitura crítica da mídia. Defende a necessidade de trabalho integrado entre educadores e jornalistas para a real compreensão do processo de produção da imprensa, construção da linguagem e da linha editorial dos veículos de comunicação.

This paper focuses on the classroom use of newspaper and magazine texts and its connection with the learning process. It criticizes the excessive usage of fragments of journalistic discourse in school textbooks, to the detriment of other text forms. The quality of journalistic narration is questioned and the risks incumbent on an acritical reading of the media. It advocates the necessity of cooperation between educators and journalists to foster an effective understanding of the news production process, to improve language construction, and to generate awareness of the media's editorial lines and policies.
