Resumo O objetivo desta pesquisa foi adaptar a Structured Interview for Assessing Perceptual Anomalies (SIAPA) para o Brasil para ser utilizada como instrumento de autorrelato. Utilizou-se uma amostra não probabilística de 854 universitários, a maioria do sexo masculino (51,4 %) e com idades entre 16 e 65 anos (M = 23,7; DP = 6,8). Após a tradução e validação semântica da SIAPA, testaram-se os parâmetros de validade e precisão por meio de análises fatoriais, coeficientes alfa de Cronbach e análises via Teoria de Resposta ao Item (TRI). Os resultados confirmaram a adequação psicométrica da medida, apontando uma solução unidimensional com altas cargas no fator geral e alta consistência interna (α = 0,88; Ω = 0,88). Acredita-se que o objetivo proposto tenha sido satisfeito, de modo que, ao final da pesquisa, contou-se com uma medida válida e fidedigna que pode ser utilizada, tanto para rastreio quanto para pesquisa, para compreender e diagnosticar anomalias perceptuais.

Abstract The purpose of this research was to adapt the Structured Interview for Assessing Perceptual Anomalies (SIAPA) for use in Brazil as a self-report tool. A non-probabilistic sample of 854 undergraduate students was used, mostly men (51.4%) and aged between 16 and 65 years (M = 23.7, SD = 6.8). After the translation and semantic validation of SIAPA, the validity and precision parameters were tested by means of factor analysis, Cronbach’s alpha coefficients, and Item Response Theory (IRT) analysis. The results confirmed the psychometric adequacy of the measure, pointing to a one-dimensional solution with high loads on the general factor and high accuracy (α = 0.88; Ω = 0.88). It is believed that the proposed objective was satisfied, so that at the end of the investigation there was a valid and reliable measure that can be used, both for screening and research, to understand and diagnose perceptual anomalies.

This study was conducted with the objective of evaluating the use of concrete or hard-packed dirt floor in broiler houses. This experiment was carried out in two different phases. The following performance parameters were studied: live weight, feed intake, feed conversion ratio, and mortality. Litter moisture, pH and temperature were measured. Litter residual contamination after cleaning and disinfection was also evaluated. A dry bulb thermometer, a wet bulb thermometer, and a black bulb thermometer were placed inside each broiler house at bird height and outside the broiler house for data collection. Environmental data were collected at 3h intervals from 00:00 to 24:00 hours during weeks 4, 5, and 6 of the grow-out. Based on the collected data, air relative humidity (RH) was determined, after which wet bulb globe temperature (WBGT) and Radiant Heat Load (RHL) were calculated. There were no differences in live performance parameters. However, total mortality and sudden death were higher in birds raised on dirt floor. On days 0, 14 and 35, litter pH was higher in the dirt floor as compared to the concrete floor, but at the end of the grow-out, this difference disappeared. There was a cubic effect of bird age on litter moisture, which increased up to day 28, and then stabilized or decreased. Litter coliform contamination was higher at the end of the grow-out as compared to that found at housing, but it was not influenced by floor type. The general thermal comfort of broiler raised on dirt floor was similar to that of broilers raised on concrete floor.

O requerimento mínimo para que um creme dental tenha potencial anticárie é ele ter fluoreto (F) na concentração de 1000 ppm, o qual porém deve estar solúvel na formulação. Assim, este estudo teve como objetivo conhecer a concentração de F solúvel em dentifrícios usados por 206 crianças brasileiras. Foram determinadas as concentrações de flúor total (FT), o qual representa a soma das concentrações de flúor solúvel (iônico e ionizável) mais o insolúvel (ligado ao abrasivo); de flúor solúvel total (FST), representando o iônico mais o ionizável na forma de monofluorfosfato de sódio (MFP) e de flúor solúvel na forma iônica (FI). A partir destas análises foram calculadas as concentrações de MFP e a % de F insolúvel (Fins). As análises foram feitas em duplicatas com eletrodo específico. A maioria dos dentifrícios usados (96%) continham fluoreto e em 84% desses a concentração de FT encontrada estava de acordo com a declarada na embalagem. Em 78% dos cremes dentais fluoretados, a concentração de FST encontrada foi igual ou superior a 1000 ppm, variando de 422,3 a 1432,3 ppm F (média ± DP de 1017,6 ± 239,4). Os dados mostram que a maioria dos cremes dentais usados pela amostra de crianças brasileiras possui concentração de F potencialmente ativo para controlar cárie.

Toothpastes should have a minimum concentration of 1000 ppm of fluoride (F) to control caries and also the active F agent must be chemically free (soluble) in the formulation. Thus, the aim of this study was to evaluate the concentration of soluble F in dentifrices used by 206 Brazilian children. The concentrations of total fluoride (TF), total soluble fluoride (TSF) and fluoride ion were determined. From these analyses, the concentrations of F as sodium monofluorophosphate (MFP) and % of insoluble F were calculated. F was analyzed with an ion specific electrode in duplicates. The majority of dentifrices used (96%) contained F and in 84% of them, TF concentration was according to that declared by the manufacturers. In the F-toothpastes, 78% showed TSF concentration ≥1000 ppm, varying from 422.3 to 1432.3 ppm F (mean ± SD of 1017.6 ± 239.4). These findings suggest that most dentifrices used by Brazilian children present available fluoride concentration for caries control.

A Síndrome da apnéia/hipopnéia obstrutiva do sono (SAHOS) apresenta estreita correlação com a obesidade, porém não está estabelecida uma relação linear de gravidade principalmente em relação aos extremos como na obesidade mórbida. OBJETIVO: Avaliar os achados clínicos e polissonográficos em pacientes com obesidade classe III e correlacionar esses achados com a presença da SAHOS. MATERIAIS E MÉTODOS: Foram selecionados consecutivamente 45 pacientes com índice de massa corpórea superior a 40Kg/m2. Todos foram submetidos a anamnese, exame físico antropométrico e polissonografia. Os achados foram comparados entre os pacientes com e sem SAHOS. RESULTADOS: 68,9% dos pacientes eram do sexo feminino e 31,1% do masculino. A idade média foi de 46,5 DP 10,8 anos, a média do IMC foi 49 DP 7Kg/m2 e a média da circunferência cervical foi 43,4 DP 5,1cm. Todos os pacientes eram roncadores habituais e 48,9% tinham queixa de hipersonolência diurna. Os achados polissonográficos mostraram que 77,8% apresentaram índice de apnéia/hipopnéia superior a cinco. Apresentaram correlação com a presença da SAHOS: idade mais jovem (p=0,02) e maior circunferência cervical (p=0,004). CONCLUSÃO: A prevalência de SAHOS foi elevada, ressaltando a importância da sua investigação em pacientes referenciados para cirurgia bariátrica. O principal marcador da SAHOS foi a circunferência cervical.

The Obstructive Sleep Apnea/Hipopnea Syndrome (OSAHS) is closely related to obesity; a linear relation, however, has not been established, particularly in morbid obesity patients. AIM: To evaluate clinical and polysomnographic findings in a group of class III obese patients, and to relate these findings with the presence or absence of OSAHS. MATERIAL AND METHOD: Forty five patients with body mass indexex (BMI) over 40Kg/m2 were selected consecutively. A clinical history, the anthropometric examination and polysomnography were undertaken in all patients. The results of a study group and a control group (with no OSAHS) were compared. RESULTS: The sample consisted of 68.9% female and 31.1% male patients. The average age was 46.5 years (SD - 10.8 years); the average BMI was 49 (SD - 7 Kg/m2) and the average neck circumference was 43.4 cm (SD - 5.1 cm). All subjects were habitual snorers and 48.9% had daytime drowsiness. Polysomnography showed that 77.8% had an apnea/hipopnea index over 5. The findings associated with OSAHS were: younger age (p=0,02) and an increased neck circumference (p=0.004). CONCLUSION: The prevalence of OSAHS was very high, which emphasizes the importance of investigating this syndrome in patients sent for bariatric surgery. The neck circumference was the best OSAHS marked in this group of patients.

Mieloningocele ocorre em frequência aproximada de 0,4 por 1000 nascidos vivos e está associada a hidrocefalia em 85% a 90%, sendo as avaliações sobre cognição esparsas na literatura. Quarenta e cinco crianças com hidrocefalia derivada e mielomeningocele foram analisadas quanto ao QI, que foi estatisticamente correlacionado com o nível motor, idade da primeira derivação, número de revisões, infecção e perímetro cefálico. A idade média foi 7,5 anos (3 a 15 anos), 16 eram do sexo masculino e 29 eram do sexo feminino. Três (6,6%) obtiveram escore de QI >110, 11 (24,5%) entre 100-110, 8 (17,7%) entre 85-100, 16 (35,5%) entre 70-85 e 7 (15,5%) entre 50-70. O QI correlacionou-se diretamente com o nível motor, sendo o resultado cognitivo melhor, em ordem decrescente, nos níveis sacral (t 0,0055), lombar baixo (t 0,0119) e lombar alto (t 0,0226). Houve melhor desempenho cognitivo nas crianças operadas até 7 dias de vida (t 0,0099), decrescendo progressivamente o resultado a partir do primeiro mês, não existindo diferença significativa entre 7 a 31 dias (t 0,1013). Houve pior resultado no grupo que apresentou infecção do sistema de derivação (t 0,0146). O prognóstico foi progressivamente pior de acordo com o número de revisões. O melhor resultado foi encontrado nas crianças com perímetro cefálico na média (t 0,0115); resultado intermediário entre --1 DP (desvio padrão) e a média (t 0,0130) e entre a média e +1DP (t 0,0256). Os piores resultados cognitivos foram encontrados nos extremos >1DP (t 0,0269) e <1DP (t 0,0042). Do ponto de vista cognitivo o tratamento cirúrgico da hidrocefalia deve ser realizado até o primeiro mês de vida, com cuidados técnicos e de assepsia, evitando complicações que culminem em revisão.

Myelomeningocele occurs in 0.4 for 1000 neonates and is associated with hydrocephalus in 85-90%, and reports on cognition are sparsely found in literature. Forty five children with treated hydrocephalus and myelomeningocele were studied in regard of IQ, and statistically correlated to functional motor level, age of the first shunt, number of revisions of shunt, infection of the shunt and circumference of the head. The medium age was of 7.5 years (3-15 years), 16 males and 29 females. Three (6.6%) had a IQ score >110, 11 (24.4%) had a score between 100-110, 8 between 85-100 (17.7%), 16 (35.5%) between 85-100 (17.7%) and 7 (15.5%) between 50-70. IQ directly correlated with motor level, having better cognitive results the children with minor functional motor disabilities. Cognition was best in children operated until the seven day of life (t 0.0099), with progressive worse results in children operated after the first month of life, no significance was observed in children operated in the period 7 to 31 days (t 0.1013). Worse results were observed in the group of patients with infection of shunts (t 0.0146). Results were progressively worse with reoperations. The best results in relation of the circumference of the head were seen with children in the medium range (t 0.0115); intermediate results were seen in patients between the medium range and-1 SD (t 0.00130) and medium range and + 1SD. The worse results were seen in patients at the extremes of >1SD (t 0.0269) and <1SD (t 0.0042). According to cognitive results the surgical treatment of hydrocephalus have to be done until the first month of life, avoiding reoperations and infections that have unfavorable impact in IQ.

Cervical lymph nodes biopsies from 31 HIV positive patients (with or without AIDS) were studied by histologic methods and immunohistochemistry (StreptABC staining of paraffin sections) to identify cellular and extracellular matrix components. The results were the following: (1) the biopsies were included in the stages of follicular hyperplasia without fragmentation FH-FF (4 cases); follicular hyperplasia with follicular fragmentation FH+FF (16 cases); follicular involution FI (6 cases) and diffuse pattern DP (5 cases); (2) the most important alteration was the germinal centers disruption due to follicle lysis, which began in the light zone; (3) there was coincidence between intrafollicular hemorrhages and segmental hyaline mycroangiopathy; (4) during the progression of the disease occurred: (a) an increase in the number of mast cells, CD68+ and Mac387+ macrophages; (b) a diffuse augment of collagen III, elastic fibers, laminin, fibronectin and proteoglycans; (c) maintenance of Factor VIII - related antigens in the vascular endothelial cells, with decrease in the expression of Ulex-Europeus I lectin. Follicular hyperplasia (FH-FF or FH+FF) was the most common histologic pattern recognized in the lymph nodes of patients without AIDS and follicular involution and difuse pattern were seen in those who had AIDS. The results indicate that the lymph node biopsies may provide important information about the evolutive stage of the disease and its prognosis.
