The Effect of Adenoidectomy or Adenotonsillectomy on Occlusal Features in Mouth-breathing Preschoolers

Purpose: The purpose of this study was to evaluate mouth-breathing and nasal-breathing children prior to surgical intervention and 28 months postoperatively, comparing the occlusal features obtained pre- and postoperatively through orthodontic study costs. Methods: The mouth-breathing (MB) group consists of 33 MB children who underwent surgery and presented a nasal-breathing (NB) pattern after surgery The control group comprised 22 NB children. The orthodontic examinations were accomplished prior to surgery (77) and an average of 28 months postoperatively (T2). Results: At T1, the MB and NB children presented no statistically significant difference in any analyzed occlusal features and measurements. At T2, the MB presented larger overjet comparing to NB children (P<.05). MB and NB groups presented statistically similar results (P>.05) concerning intercanine and intermolor distances, second primary molar terminal plane and canine relationship, overbite, crossbite, and open bite. From T1 to T2, the MB and NB groups showed a statistically significant difference in the molar terminal plane. Conclusion: Neither the breathing pattern nor the surgery had any effect on occlusal features in 3- to 6-year-olds.

Estudos de confiabilidade e validade do questionário de respostas socialmente habilidosas versão para pais - QRSH-Pais

Constata-se uma carência de instrumentos que avaliem habilidades sociais de crianças da educação infantil, de modo a predizer problemas comportamentais e instrumentar ações preventivas, justificando a proposição de instrumentos. Objetivou-se testar propriedades psicométricas de validade e confiabilidade do Questionário de Respostas Socialmente Habilidosas para pais (QRSH-Pais). Foram avaliados por suas mães 131 pré-escolares, diferenciados em subgrupos com e sem problema de comportamento com base na Escala Comportamental Infantil (ECI-Pais e ECI-Professor). Procedeu-se aos estudos de validade discriminativa e concorrente e a verificação da consistência interna pelo alfa de Cronbach. Os resultados apontaram para indicadores positivos de consistência interna e validade discriminativa. Considera-se que o questionário está aferido para avaliação de habilidades sociais em pré-escolares, podendo ser utilizado em pesquisas de avaliação e de intervenção clínica controlada.

Reading, equivalence, and recombination of units: A replication with students with different learning histories

First graders, preschoolers, special education students, and adults received a reading program in which they learned to match printed to dictated words and to construct (copy) printed words. The students not only learned to match the training words but also learned to read them. In addition, most of the students learned to read new words that involved recombinations of the syllables of the training words. The results replicate and extend the generality of a prior analysis of a reading program based on stimulus equivalence and recombination of units.

A Qualidade da Interação Positiva e da Consistência Parental na sua Relação com Problemas de Comportamentos de Pré-Escolares

Studies have shown a relationship to exist between behavior problems in children and quality of parental practices such as communication, expressivity, consistency, and monitoring. This study aimed at describing relationships that parents have with their preschool children, and also at relating parenting skills to child behavior. We compared fathers' and mothers' social educational skills in two groups of children, with or without behavior problems at school. Research was conducted in a town in the State of Sao Paulo, BR. Participants were biological mothers and fathers of 48 preschoolers; twenty-five children presented behavior problems at school, and 24 had high social skills. Parents were individually interviewed at home. Results showed that fathers and mothers of socially skilled children were more consistent in their practices. They were more able to identify and describe their children's socially skilled behaviors. They also reported they gave more positive feedbak for their children's good behavior.

Characterization of language disorders in children with lead poisoning

Background: lead poisoning can have a negative impact on the neuropsychological functions, including language, due to the damage it causes to the developthent of the Central Nervous System. Aim: to verify the occurrence of language disorders in children who suffered from led poisoning and to verify the correlation between the lead concentration level in the blood and the language disorders presented by the children. Method: language evaluation of 20 preschoolers, with lead concentration level in the blood above 10μg/dl. Results: 13 children presented language impairment involving only phonology or more than one language subsystem. The statistical analysis indicated that no correlation exists between the severity of the language impairment and the concentration levels of lead. Conclusion: the number of children with language impairment indicates lead poisoning as a risk factor for the present alterations, even though other risk factors for language disorders were found and the absence of correlation between the investigated variables.

Prevalência de hábitos de sucção não nutritivos em pré-escolares e a percepção dos pais sobre sua relação com maloclusões

Este estudo transversal e descritivo objetivou verificar a prevalência de hábitos de sucção em pré-escolares e a percepção dos pais sobre a relação com a ocorrência de maloclusões. A população do estudo constituiu-se por uma amostra representativa de pais de pré-escolares de 4 meses a 6 anos de idade. Utilizou-se um questionário semiestruturado, composto por questões abertas e fechadas, referentes à frequência e conhecimentos dos pais frente aos hábitos de sucção não nutritivos. Dos 356 participantes da pesquisa, 70,8% afirmaram que as crianças apresentavam algum hábito bucal, sendo a sucção de chupeta o mais frequente (45,6%). Apesar da grande maioria dos pesquisados (97,1%) relatarem saber que os hábitos podiam causar prejuízo aos dentes, 70,2% deles já haviam oferecido chupeta à criança, na maioria das vezes para acalmá-la (61,8%). Houve associação estatisticamente significativa entre a oferta da chupeta à criança e o conhecimento sobre a relação da presença de hábitos não nutritivos e a ocorrência de maloclusão (p < 0,0001 e Qui-quadrado = 60,123). A prevalência de hábitos bucais na população estudada é alta e, apesar da maioria dos pais saberem que o hábito de sucção de chupeta pode causar danos à saúde bucal, ofertavam a chupeta a fim de acalmar a criança.

Achados timpanométricos em um grupo de escolares

PURPOSE: to characterize and compare the tympanometric findings in a group of preschoolers. METHOD: 112 preschoolers were evaluated, both genders, aged from four years old to five years and eleven months old who attended a Municipal School of Early Childhood Education in the suburbs of Marilia city- SP. Tympanometry was used as triage procedure. It was considered that the child PASSED in the triage when it presented an A type tympanometric curve, bilaterally, being reevaluated in case of failure. RESULTS: it was observed a high failure index (63.4%) in the studied population. The older female preschoolers presented a higher index of A type tympanograms, in both ears. There was a higher incidence of failure in male preschoolers aged from four years to four years and eleven months. CONCLUSION: in this sample, there was a high index of tympanometric alteration. There was a tendency among younger male students to present a higher index of tympanometric alteration when compared to older female preschoolers, this difference was not statistically significant.

Preschool children and excess weight: the impact of a low complexity intervention in public day care centers

Introduction: childhood obesity is a major public health problem, affecting children even at early ages. Objective: to assess the impact of dietary intervention and relatively simple physical activity on the nutritional state of preschoolers. Method: this was an intervention study in public daycare centers targeting children from 2 to 4 years of age, in the State of São Paulo. The sample consisted of 9 daycare centers covering 578 children, with 264 children in the intervention group (IG) and 314 in the comparison group (CG). Intervention was focused on modifications in diet and physical activity, avoiding overloading the routine of daycare centers, for duration of one year. A zBMI score > 1 (zBMI) and < 2 was considered risk of being overweight, and > 2 zBMI was considered excess weight (overweight and obese). Analysis was done by frequency calculations, comparisons of proportions by χ2, mean comparisons by t-student and calculations according to Pearson’s correlation coefficient. Results: IG showed an inverse correlation between the initial zBMI of the children and the difference with the zBMI at the end of the intervention (rP = -0.39, p <0.0001). The mean difference of zBMI of the overweight children in IG between the beginning and the end of the study period was negative (-0.46 z score), indicating weight reduction, while the children in the CG was positive (+0. 17 z score) (p = 0.0037). Conclusion: intervention in diet and physical activity in overweight preschool children in daycare centers could have a favorable impact on the evolution of their nutritional state.
