Orientador: Flávio Luís Moreira / Resumo: A lesão lábio-palatal é uma malformação congênita com incidência, no Brasil, de 1:600 nascimentos. Quando a fissura acomete o palato, os problemas alimentares mais observados são sucção insuficiente, perdas alimentares, cansaço ao sugar com gasto energético aumentado, deglutição excessiva de ar, ingestão inadequada, ganho de peso insuficiente e comprometimento do estado nutricional. São crianças que dificilmente aleitam ao seio e ainda são mais expostas a infecções respiratórias e otites médias. A correção das malformações implica em vários processos cirúrgicos iniciados em torno do terceiro mês de idade, com o fechamento do lábio e o palato sendo fechado entre 12 a 18 meses. Após esta idade são comuns cirurgias de revisão de palato, secundária de lábio, de columela, etc. Todos estes processos acabam comprometendo mais ainda o estado nutricional dos pacientes. Tendo em vista os aspectos acima, foi proposto no presente estudo avaliar o estado nutricional pré-cirúrgico de crianças de 2 a 7 anos, portadoras de fissura lábio e/ou palatal, segundo os indicadores dietéticos, antropométricos e laboratoriais e segundo o tipo de fissura. A população estudada foi constituída por quatrocentos e oitenta e nove pacientes de ambos os sexos, não sindrômicos, após aceite dado por escrito pelo responsável legal de cada criança. Os pacientes de cada faixa etária foram subdivididos em 3 grupos de acordo com o tipo de fissura e submetidos às avaliações dietéticas, antropométricas e laboratoriais estabelecidas. Os dados obtidos foram comparados com os valores padronizados por estudos internacionalmente reconhecidos e também receberam tratamento estatístico pertinente. O nível sócio-econômico foi avaliado através da classificação padronizada pela instituição. Foi observado que 46,6% das crianças apresentou...

The most frequent feeding problems associated with cleft palate are sucking inability, food losses, tiredness upon sucking with increased energetic demand, excessive intake of air, improper ingestion, insufficient weight gain and disturbances of the nutritional status. These children are seldom breastfed and are more prone to respiratory infections and otitis media. Correction of the malformation comprises several surgical procedures initiated around three months of age, when lip surgery is performed, followed by palatal closure between 12 and 18 months old. After this age range there may be secondary palate or lip surgeries, columella lengthening, etc. All these interventions may pose even more damage to the nutritional status of these patients. Considering all these aspects, the present study was proposed in order to evaluate the pre-surgical nutritional status of children aged 2 to 7 years old presenting with cleft lip and/or cleft palate, according to dietary, anthropometric and laboratory indexes and according to the type of cleft. The study population comprised four hundred and eighty-nine patients of both genders, without syndromes, after achievement of written consent from the caretaker of each child. Patients in each age range were subdivided in three groups according to the type of cleft and submitted to the established dietary, anthropometric and laboratory evaluations. The obtained information was compared to standardized values proposed by worldwide recognized studies and proper statistical analyses were also performed. The socioeconomic level was evaluated by means of the standardized classification employed at the institution. Calorie and protein intakes were above the recommended levels for the age range for 46.6% and 98.8%... (Complete abstract click electronic address below) / Doutor

Neste estudo, verificamos a ocorrência de sintomas de depressão, compulsão alimentar e distúrbios do sono em estudantes do terceiro ano do ensino médio e de curso pré-vestibular. Foi realizado um estudo transversal, descritivo. A amostra de 529 estudantes (M=241; F=288) de sete escolas públicas e privadas e dois cursos pré-vestibulares, de um bairro de classe média, da cidade de São Paulo, na faixa etária entre 16 e 19 anos. Os instrumentos utilizados foram: Inventário Beck de Depressão (BDI), Questionário sobre Padrões Alimentares e Peso - Revisado (QEWP-R) e o Índice de Qualidade do Sono de Pittsburgh (IQSP). A análise dos dados indica maior percentual de sintomatologia depressiva no grupo feminino e entre estudantes dos cursinhos. Verificou-se a presença de indícios de compulsão alimentar com maior percentual nos estudantes das escolas particulares. Em relação aos distúrbios do sono mostram diferenças significativas no período de estudo, problemas para ficar acordado, qualidade subjetiva do sono, latência, duração do sono, uso de medicação, eficiência habitual do sono, sonolência diurna e distúrbios do sono e número de pessoas na casa. Houve Associação entre distúrbios do sono e indícios de compulsão alimentar, distúrbios do sono e sintomatologia depressiva. Concluímos que na população estudada existe a ocorrência de sintomatologia depressiva, indícios de episódios de compulsão alimentar e distúrbios do sono / Abstract: Adolescence is a period of transition marked by significant transformations in biochemical, physiological and psychosocial aspects, leading to anxiety and anguish, which consist in risk factors for the appearance of some type of disturbance. In this study, we verified the occurrence of symptoms of depression, eating compulsion and sleep disturbances in third-year intermediate students and students enrolled in courses for university entrance examination. This was a transversal and descriptive study comprising 529 students (241 males; 288 females) from seven public and private schools and two courses for university entrance examination located in a middle-class district in the city of São Paulo, in the age group of 16-19 years. The instruments used were: Beck Depression Inventory (BDI), Questionnaire on Eating and Weight Patterns - Revised (QEWP-R) and the Pittsburgh Sleep Quality Index (PSQI). The data analysis indicated a major percentage of depressive symptomatology in the group of females and among students of the courses. It was verified a major percentage of eating compulsion signs in students of private schools. Concerning sleep disturbances, they showed significant differences regarding the period of study, difficulty staying awake, subjective quality of sleep, latency, sleep duration, medication use, habitual sleep efficiency, daytime sleepiness, and number of people at home. There was an association between sleep disturbances and eating compulsion signs, as well as sleep disturbances and depressive symptomatology. We could conclude that there was an occurrence of depressive symptomatology, signs of eating compulsion and sleep disturbances / Doutorado / Saude da Criança e do Adolescente / Doutor em Saude da Criança e do Adolescente

The occurrence of mid-latitude spread F (SF) over South Africa has not been extensively studied since the installation of the DPS-4 digisondes at Madimbo (30.88◦E, 22.38◦S), Grahamstown (33.32◦S, 26.50◦E) and Louisvale (28.51◦S, 21.24◦E). This study is intended to quantify the probability of the occurrence of F region disturbances associated with ionospheric spread F (SF) and L-band scintillation over South Africa. This study used available ionosonde data for 8 years (2000-2008) from the three South African stations. The SF events were identified manually on ionograms and grouped for further statistical analysis into frequency SF (FSF), range SF (RSF) and mixed SF (MSF). The results show that the diurnal pattern of SF occurrence peaks strongly between 23:00 and 00:00 UT. This pattern is true for all seasons and types of SF at Madimbo and Grahamstown during 2001 and 2005, except for RSF which had peaks during autumn and spring during 2001 at Madimbo. The probability of both MSF and FSF tends to increase with decreasing sunspot number (SSN), with a peak in 2005 (a moderate solar activity period). The seasonal peaks of MSF and FSF are more frequent during winter months at both Madimbo and Grahamstown. In this study SF was evident in ∼ 0.03% and ∼ 0.06% of the available ionograms at Madimbo and Grahamstown respectively during the eight year period. The presence of ionospheric irregularities associated with SF and scintillation was investigated using data from selected Global Positioning System (GPS) receiver stations distributed across South Africa. The results, based on GPS total electron content (TEC) and ionosonde measurements, show that SF over this region can most likely be attributed to travelling ionospheric disturbances (TIDs), caused by gravity waves (GWs) and neutral wind composition changes. The GWs were mostly associated with geomagnetic storms and sub-storms that occurred during periods of high and moderate solar activity (2001-2005). SF occurrence during the low solar activity period (2006-2008)can probably be attributed to neutral wind composition changes.
