The Role of Sensory Modulation Deficits and Behavioral Symptoms in a Diagnosis for Early Childhood

To contribute to the validation of the sensory and behavioral criteria for Regulation Disorders of Sensory Processing (RDSP) (DC:0-3R, 2005), this study examined a sample of toddlers in a clinical setting to analyze: (1) the severity of sensory modulation deficits and the behavioral symptoms of RDSP; (2) the associations between sensory and behavioral symptoms; and (3) the specific role of sensory modulation deficits in an RDSP diagnosis. Based on clinical observations, 78 toddlers were classified into two groups: toddlers with RDSP (N = 18) and those with‘‘other diagnoses in Axis I/II of the DC:0-3R’’ (OD3R; N = 60). The parents completed the Infant Toddler Sensory Profile and the Achenbach Checklist. The results revealed that the RDSP group had more severe sensory modulation deficits and specific behavioral symptoms; stronger, although not significant, associations between most sensory and behavioral symptoms; and a significant sensory modulation deficit effect. These findings support the validity of RDSP.

MORBIDITY AND MORTALITY DUE TO AIDS: A STUDY OF BURDEN OF DISEASE AT A MUNICIPAL LEVEL

Introduction: The purpose of measuring the burden of disease involves aggregating morbidity and mortality components into a single indicator, the disability-adjusted life year (DALY), to measure how much and how people live and suffer the impact of a disease. Objective: To estimate the global burden of disease due to AIDS in a municipality of southern Brazil. Methods: An ecological study was conducted in 2009 to examine the incidence and AIDS-related deaths among the population residing in the city of Tubarao, Santa Catarina State, Brazil. Data from the Mortality Information System in the National Health System was used to calculate the years of life lost (YLL) due to premature mortality. The calculation was based on the difference between a standardized life expectancy and age at death, with a discount rate of 3% per year. Data from the Information System for Notifiable Diseases were used to calculate the years lived with disability (YLD). The DALY was estimated by the sum of YLL and YLD. Indicator rates were estimated per 100,000 inhabitants, distributed by age and gender. Results: A total of 131 records were examined, and a 572.5 DALYs were estimated, which generated a rate of 593.1 DALYs/100,000 inhabitants. The rate among men amounted to 780.7 DALYs/100,000, whereas among women the rate was 417.1 DALYs/100,000. The most affected age groups were 30-44 years for men and 60-69 years for women. Conclusion: The burden of disease due to AIDS in the city of Tubarao was relatively high when considering the global trend. The mortality component accounted for more than 90% of the burden of disease.

Ascaris lumbricoides: reinfection in children bearing an established worm burden

To clarify the existance of reinfection in children bearing an established Ascaris lumbricoides infection, the authors evaluated the weight and the length of worms collected from ten cases of ascaridiasis. The worm burden was greater than 27 worms in nine cases. In seven cases the weight and the length of worms showed little variation, with unimodal distribution of values, suggesting that all the worms in each case belong to the same population, originated from a single brood infection or from successive infections over small time intervals. In three cases there was great variation in worm size indicated by the different values for the means and medians and by the high values for the standard deviation and coefficient of variation. In these three cases there was a bimodal distribution of worm's size suggesting the coexistance of two distinct populations: one, less numerous, composed of mature worms and the other, more numerous, composed ofimmature worms, in two cases, and two distinct populations of immature worms in one case. The existance of worms in different stages of maturation indicates that the less mature population was acquired when the mature worms were established in the gut. These results indicate that the reinfection with Ascaris in children bearing an established infection is not rare and resistance induced by a preexisting infection is not the rule.

Frequency of myocarditis in cases of fatal meningococcal infection in children: observations on 31 cases studied at autopsy

The frequency of myocarditis associated with meningococcal disease in children was reported only in two autopsied series (United States and South Africa). Here we report the frequency of associated myocarditis in 31 children who died of meningoccal infection at Hospital Infantil N.S. da Glória in Vitória, Espirito Santo State, Brazil. The diagnosis was confirmed by isolation of Neisseria meningitidis . At least three sections of fragments of both atria and ventricles were studied using the Dallas Criteria for the morphologic diagnosis of myocarditis. The mean age was 47.6 ± 39.8 months and the mean survival time after the onset of symptoms was 46.1 ± 26.5h (12-112h). Myocarditis was present in 13 (41.9%) patients, being of minimal severity in 11 cases and of moderate severity in 2 cases. There were no cases with severe diffuse myocarditis. The frequency of myocarditis was not influenced by sex, presence of meningitis, survival time after the onset of symptoms or use of vasoactive drugs. The frequency of myocarditis reported here was intermediate between the values reported in the only two case series published in the literature (57% in the United States and 27% in South Africa). Although our data confirm the high frequency of myocaditis in meningoccal disease, further investigations are necessary to elucidate the contribution of myocarditis to myocardial dysfunction observed in cases of meningococcal infection in children.

Os autores descrevem caso de enterobíase peritoneal apresentando-se como granuloma necrosante, em adolescente com tumor do seio endodérmico do ovário. O diagnóstico foi estabelecido por biópsia de nódulo do epíploon, durante laparotomia para reestadiamento de câncer de ovário após tratamento clínico. Nódulos granulomatosos peritoneais causados por parasitas podem simular metástases, confundindo o estadiamento de neoplasias.

Avaliação do impacto na infestação por Aedes aegypti em tanques de cimento do município de Canindé, Ceará, Brasil, após a utilização do peixe Betta splendens como alternativa de controle biológico

Canindé apresenta uma população de 71.235 habitantes. Em abril de 2001 iniciou a utilização de peixes larvófagos em tanques de cimento, localizados ao nível do solo, como forma de controle biológico para larvas de Aedes aegypti. Durante a visita do agente, ao invés de se tratar os tanques com larvicida, colocou-se um espécime do peixe Betta splendens por depósito. O presente trabalho teve como objetivo avaliar os resultados desta intervenção. Com os levantamentos do número de imóveis e depósitos existentes, estimou-se este número mês a mês determinando então o número de depósitos existentes por imóvel. Com esta estimativa e o número de imóveis visitados mensalmente analisou-se a infestação deste tipo de depósito. Em janeiro de 2001, 70,4% dos tanques examinados apresentavam larvas; e apenas 7,4% em janeiro de 2002. Em dezembro de 2002 este índice caiu para 0,2%. Demonstrou-se com clareza a capacidade do Betta splendens como agente de controle biológico, em tanques de cimento, reduzindo 320 vezes a infestação deste tipo de recipiente de grande volume.

Pesquisa de anticorpos anti PGL-I através de ELISA em tatus selvagens do Brasil

Tatus têm sido envolvidos na transmissão da hanseníase e considerados como fonte de Mycobacterium leprae em muitas publicações. Médicos de partes dos EUA consideram o contato com tatus um fator de risco para hanseníase. Entretanto, há um desafio associado ao papel do tatu na perpetuação da hanseníase no Continente Americano. Foi pesquisada a presença de anticorpos anti-PGL-I em tatus selvagens de áreas endêmicas em hanseníase do Estado do Espírito Santo, Brasil, através de ELISA realizado em amostras de soro de 47 animais. Elisa positivo foi encontrado em 5 (10.6%) tatus. Tatus infectados podem ter algum papel na transmissão da hanseníase disseminando bacilos no meio ambiente, talvez tornando mais difícil a interrupção da cadeia de transmissão e redução do número de casos novos de hanseníase. A técnica de ELISA é um eficiente método para investigação soroepidemiológica da presença do Mycobacterium leprae em tatus.

Avaliação oftalmológica em pacientes com AIDS e neurotoxoplasmose

INTRODUÇÃO: Descrever os achados fundoscópicos em pacientes com AIDS e neurotoxoplasmose em fase ativa. MÉTODOS: Foi desenvolvido estudo prospectivo tipo série de casos incluindo 70 pacientes, de ambos os sexos, com idade variando de 20 a 63 anos, internados nas enfermarias de três hospitais públicos da Cidade do Recife, Pernambuco, com diagnósticos de AIDS e neurotoxoplasmose firmados segundo os critérios do Centers for Disease Control and Prevention (1992), no período de janeiro a outubro de 2008. Os pacientes se caracterizavam por: primeiro episódio de neurotoxoplasmose (65; 92,9%) ou recidiva (5; 7,1%); desconhecimento de ter AIDS (23; 32,9%), contagem média de linfócitos T CD4 de 139,8 ± 3,04 células/mm3 e carga viral média igual a 137.080 ± 39.380 cópias/mL. Todos foram submetidos a exame oftalmológico, consistindo de: inspeção ocular; aferição da acuidade visual; investigação da função muscular extrínseca ocular e fundoscopia, empregando oftalmoscópio indireto binocular (modelo OHN 3.5 (Eyetec®) e lente externa de 20 dioptrias (Volk®). RESULTADOS: Os achados consistiram em: exsudatos algodonosos retinianos (8,6%), constricção arteriolar difusa leve (8,6%); lesões de retinocoroidite cicatricial, características de toxoplasmose ocular (5,7%), atrofia do epitélio pigmentar retiniano (2,9%), descolamento da retina (2,9%), aumento de escavação papilar (1,4%), degeneração periférica retiniana (1,4%), macroaneurisma (1,4%), papiledema bilateral (1,4%), tração vítreo-retiniana (1,4%). CONCLUSÕES: Pacientes com AIDS e neurotoxoplasmose podem apresentar alterações fundoscópicas características da toxoplasmose ocular, na forma ativa ou cicatricial, relacionadas ao HIV ou, ainda, a outras doenças oportunistas ou sistêmicas, podendo ser de grande auxílio num tratamento integral do paciente por uma equipe multiprofissional.

Antibody levels in children after 10 years of vaccination against hepatitis B: a brazilian community-based study

INTRODUCTION: It is known that the hepatitis B (HB) vaccine is effective, but it is alarming that sudden drops of antibody levels may coincide with the onset of adolescence. METHODS: Antibody levels against HB vaccine surface antigen (anti-HBs) and HB vaccine core antigen (anti-HBc) were measured on the blood samples of children with a mean age of 11.4 years. RESULTS: About 54.8% had protective levels of anti-HBs. Of those who were anti-HBc-positive (4.4%), an average of 218.4 anti-HBs mIU/mL was found. CONCLUSIONS: Immunological protection was found in the majority of children. However, more studies are needed to elucidate the heritability of nonresponders and establish strategies against such events.

Analysis of sandflies (Diptera: Psychodidae) in Barra do Garças, State of Mato Grosso, Brazil, and the influence of environmental variables on the vector density of Lutzomyia longipalpis (Lutz & Neiva, 1912)

INTRODUCTION: Leishmaniasis is an infectious and parasitic zoonotic, non-contagious, vector-borne disease caused by protozoa of the genus Leishmania. In Brazil, the major vector of Leishmania (Leishmania) infantum chagasi (Cunha &amp; Chagas, 1934) is Lutzomyia longipalpis. Barra do Garças, State of Mato Grosso, was designated as a priority area by the Brazilian Ministry of Health for american visceral leishmaniasis, and it is important to identify the vector species present in this municipality. Our objective was to raise sandflies and study the influence of environmental variables on the vector density of Lutzomyia longipalpis. METHODS: We performed entomological monitoring in 3 districts using Centers for Disease Control and Prevention (CDC) light traps and recorded human cases of american visceral leishmaniasis in the city. We calculated the relative frequency and richness of sandflies and applied a transfer function model to the vector density correlate with relative humidity. RESULTS: The sandfly population was composed of 2 genera and 27 species, totaling 8,097 individuals. Monitoring identified Lutzomyia longipalpis (44%), followed by Lutzomyia lenti (18.9%), Lutzomyia whitmani (13.9%), Lutzomyia carmelinoi (9.1%), Lutzomyia evandroi (5.1%), Lutzomyia termitophila (3.3%), Lutzomyia sordellii (1.9%), and 20 other species (<4%). The male:female ratio was 3.5:1. We observed high species diversity (Dα = 6.65). Lutzomyia longipalpis showed occurrence peaks during the rainy season; there was a temporal correlation with humidity, but not with frequency or temperature. CONCLUSIONS: The presence of Lutzomyia longipalpis in the urban area of Barra do Garças underscores the changing disease profile, which was previously restricted to the wild environment.
