Survey assessment of parental perceptions regarding head lice

Background Head lice constitute a problem in children. Each year, numerous cases of pediculosis occur worldwide. Little work has been performed to evaluate the understanding, opinions, and actions of populations regarding head lice. These areas are important as they enable clinicians and educators to alert parents on how to avoid treatments that are innocuous or of high risk to patients.Methods A cross-sectional study was performed by interviewing the heads of households of 100 randomly chosen residences within the study area.Results The results obtained showed that 13% were infested during the first week of the survey, and 86% in the 24 weeks prior to the study. The number of positive cases increased with increasing resident number, and decreased in families with parents with a higher educational level. Itching was the principal clinical manifestation and caused sleep compromise in 65% of respondents. Innocuous and unhealthy practices to combat infestation, such as the use of inflammables and home insecticides, were common.Conclusion The results showed that certain beliefs generated worry and confusion in parents, who blamed head lice as the cause of various health problems which were not due to this insect.

NESTLING BEHAVIOR and PARENTAL CARE of THE COMMON POTOO (NYCTIBIUS GRISEUS) IN SOUTHEASTERN BRAZIL

We recorded and quantified the nocturnal activity and parental care of a brooding Common Potoo (Nyctibius griseus) using an infrared camera in southeastern Brazil. Parents alternated care of the nestling and decreased their presence as the nestling grew. Nestling feeding on passing insects while sitting on the nest, movements on the nest, wing exercising, preening, and defecating were recorded primarily while it was alone. The frequency of begging calls per hour was higher when the nestling was accompanied by one of the parents. Nocturnal recordings of this species on the nest revealed behaviors that were not cited in past studies, including: feedings bouts on passing flies performed by the nestling and adults, nestling defecation, and nestling plumage maintenance. The well-known plus newly quantified behaviors of the Common Potoo reinforce their value to survival during the long nestling period. Received 24 May 2010. Accepted 14 September 2010.

Larvas de Scinax rizibilis (Bokermann) (Anura, Hylidae): avaliando o efeito parental

A controlled experiment, related with the mating system of Scinax rizibilis (Bokermann, 1964), was conducted to assess if larval variation could be due to size of male or its ability to manage an amplexus. Adult individuals were caught during breeding activity (from February 1993 to January 1994), in a temporary pond in the municipality of Ribeirão Branco. São Paulo State, southeastern Brazil. The duration of the larval period was not different between tadpoles of large and small males, nor was it different between tadpoles coming from natural or artificial pairs. The reproductive status of the male (if it had managed an amplexus) also did not influence the total length nor the mass of the tadpoles close to metamorphosis. However, tadpoles of larger and heavier males were, on average, approximately 5.5% and 11% larger and heavier, respectively, than tadpoles of smaller males. These results indicate that the breeding system of S. rizibilis could potentially have a directional effect on the larval characteristics.

Atividade física: prevalência, fatores relacionados e associação entre pais e filhos

OBJETIVO: Analisar a associação entre a prática esportiva de adolescentes e seus respectivos pais. MÉTODOS: Estudo transversal envolvendo 1.111 adolescentes de ambos os gêneros, com idade entre dez e 17 anos e seus respectivos responsáveis. Entre pais e filhos, o envolvimento em práticas esportivas de intensidade moderada e/ou vigorosa foi avaliado por meio de questionário. A condição econômica, o gênero e a idade foram considerados variáveis de confusão. A regressão logística binária avaliou a magnitude das associações indicadas pelo teste do qui-quadrado. RESULTADOS: em ambos os gêneros, o envolvimento dos pais foi associado com um maior engajamento por parte do adolescente em práticas esportivas (masculino: OR2,3; IC95%1,0-5,3; feminino: OR2,7; IC95%1,3-5,1). Porém, o envolvimento materno foi associado apenas com a atividade física no sexo feminino (OR2,4; IC95%1,4-3,8). CONCLUSÕES: A prática esportiva dos adolescentes está associada com a prática de seus pais e o gênero dos pais exerce efeitos distintos em tal fenômeno.

Comunicação e envolvimento: possibilidades de interconexões entre família-escola?

Família e escola são considerados contextos primordiais para o desenvolvimento humano, sendo desejável que haja um elo adequado entre esses espaços. Pautado nessa premissa, este artigo objetiva analisar as relações estabelecidas entre a escola e a família de crianças com baixo rendimento escolar, salientando que a escola pesquisada adota o regime de progressão continuada. O referencial teórico do estudo foi a perspectiva bioecológica de Bronfenbrenner. Participaram da pesquisa seis crianças, seus respectivos responsáveis e professoras. A coleta de dados consistiu de entrevistas semiestruturadas e observações. Os dados foram coligidos em duas categorias: envolvimento e comunicação. Embora os resultados destaquem a comunicação como principal veículo de trocas entre os dois contextos, essa necessita ser aprimorada. A família e a escola compreendem que devem trabalhar em colaboração, mas tal relação precisa ser reconstruída, pois se mostra assimétrica e repleta de preconceitos.
