Osteochondritis dissecans of the hip in legg-calvé-perthes disease: case report and review / Osteocondrite dissecante do quadril na doença de legg-calvé-perthes: relato de caso e revisão

ABSTRACT Introduction: Legg-Calvé-Perthes disease (LCPD) is the idiopathic osteonecrosis of the capital femoral epiphysis in children. It is a self-healing condition, and the morphology of the hip may vary according to the severity of the disease, among several other factors. The treatment focuses on attempts to prevent femoral head collapse, obtain functional hip motion recovery, and reduce pain. Osteochondritis Dissecans (OCD) of the femoral head has been reported in 2% to 7% of patients diagnosed with healed LCPD. Although OCD may remain asymptomatic, the osteochondral fragment has the potential to become unstable, evolving into symptoms of pain, locking, catching, and snapping. Case report: We present a case report of a ten-year-old boy with an OCD lesion following LCPD who underwent effective osteochondral fixation through the surgical hip dislocation approach. The patient evolved to excellent functional recovery at 1 year post-operatively. Discussion: The surgical hip dislocation approach allows anatomical fixation of the OCD fragment, as well as improvement of hip biomechanics, decreasing pain, improving range of motion and joint congruency, and preserving the native articular cartilage. It also gives the surgeon the opportunity to assess hip stability, femoroacetabular impingement and labral tears, allowing a wide variety of options for the treatment of the healed LCPD. Level of Evidence IV; Type of study Case Report.

RESUMO Introdução: A Doença de Legg-Calvé-Perthes (DLCP) é a osteonecrose idiopática da epífise femoral proximal em crianças. É uma condição auto resolutiva, porém a morfologia final do quadril pode variar de acordo com a gravidade da doença. O tratamento concentra-se na tentativa de prevenir o colapso da cabeça femoral, obtendo recuperação funcional do movimento do quadril e redução da dor. A osteocondrite dissecante (OCD) da cabeça femoral foi relatada em 2% a 7% dos pacientes diagnosticados com DLCP já curada. Embora a OCD possa permanecer assintomática, o fragmento osteocondral tem potencial para se tornar instável, evoluindo para sintomas de dor, bloqueio, impacto e estalido. Relato de caso: Apresentamos o relato de caso de um menino de 10 anos com OCD da cabeça femoral após DLCP, submetido à fixação osteocondral do fragmento por meio da abordagem cirúrgica de luxação do quadril. O paciente evoluiu com excelente recuperação funcional 1 ano após a cirurgia. Discussão: A abordagem cirúrgica da luxação do quadril permite a fixação anatômica do fragmento da OCD, bem como a melhora da biomecânica do quadril, diminuindo a dor, melhorando a amplitude de movimento e a congruência articular e preservando a cartilagem articular nativa. Também dá ao cirurgião a oportunidade de avaliar a estabilidade do quadril, impacto femoroacetabular e lesões labrais, permitindo uma ampla variedade de opções para o tratamento das sequelas da DLCP. Nível de evidência IV; tipo de estudo Relato de Casos.

Early stimulation for neuropsychomotor development in children with microcephaly: a systematic review / Estimulação precoce para o desenvolvimento neuropsicomotor de crianças com microcefalia: uma revisão sistemática

ABSTRACT Objective: To systematically review studies on the effects of early stimulation on the neuropsychomotor development of children with microcephaly. Data source: A systematic review was conducted in PubMed/MEDLINE, Virtual Health Library, and Cochrane Library databases. Studies that addressed the use of early stimulation in playful and interactive environments in children with microcephaly were included. There were no restrictions on the publication date or language of the studies. The outcomes assessed were muscle tone, social interaction, fine and gross motor skills, intelligence quotient, socioemotional and adaptive behavior of the child. The methodological quality and the scientific evidence level were assessed using the Risk of Bias in Non-randomized Studies of Interventions, the Revised Cochrane risk of bias tool for randomized trials and the Grading of Recommendations Assessment, Development and Evaluation. Data synthesis: 264 articles were identified, but only 7 met the eligibility criteria. The included studies had a total population of 125 individuals, with sample sizes ranging from 1 to 71 participants. Conclusions: The studies showed low evidence of an effect of early intervention on the outcomes muscle tone, social interaction, fine and gross motor skills, intelligence quotient, and socioemotional and adaptive behavior in children with microcephaly. However, further randomized clinical trials are needed.

Brazilian version of the CHOP INTEND scale: cross-cultural adaptation and validation / Versão brasileira da escala CHOP INTEND: adaptação transcultural e validação

Abstract Background Spinal muscular atrophy (SMA) is a rare genetic disease that causes progressive muscle weakness and impacts motor function. The type I is the most severe presentation and affects infants before 6 months old. In addition, the instruments available for assessing motor function have limitations when applied to infants with neuromuscular diseases and significant muscle weakness. Objective To translate, cross-culturally adapt, and validate the Children's Hospital of Philadelphia Infant Test of Neuromuscular Disorders (CHOP INTEND) to Brazilian Portuguese. Methods The present study comprised the translation, synthesis of translations, backtranslation, consolidation by a committee of experts, and test of the final version of the CHOP INTEND in 13 patients with SMA type I. We also assessed the content validity and reliability of the translated version. Results The scale was translated considering semantic, structural, idiomatic, and cultural aspects. All agreement rates were > 0.8, the overall content validity index of the instrument was 0.98, and inter-rater reliability using the intraclass correlation coefficient was 0.998. Conclusion The Brazilian version of the CHOP INTEND met semantic and technical equivalence criteria with the original version and was valid and reliable for patients with SMA type I.

Relación entre biometría fetal, producto de acumulación de los lípidos y condición trófica al nacer / Relationship between fetal biometry, lipid accumulation product and the trophic condition at birth

Fundamento: Las alteraciones del estado nutricional materno generalmente se relacionan con desviaciones del crecimiento fetal, que pueden detectarse por los parámetros biofísicos fetales e identifican la posible condición trófica al nacer. Objetivo: Determinar la posible relación entre los parámetros biométricos fetales, la condición trófica al nacer y el producto de acumulación de los lípidos. Metodología: Se realizó un estudio transversal en el Policlínico Chiqui Gómez Lubian del municipio Santa Clara, durante el año 2019, en una población de 253 gestantes normopeso supuestamente sanas al inicio de la gestación. La muestra no probabilística fue de 144 gestantes. Las variables de estudio fueron: producto de acumulación de los lípidos, biometría fetal y condición trófica al nacer. Se utilizaron métodos teóricos, empíricos y estadísticos. Resultados: En el segundo trimestre ningún parámetro biométrico coincidió con la condición al nacer de pequeño, mientras que para el grande coincidieron las circunferencias cefálica y abdominal. En el tercer trimestre la longitud del fémur y la circunferencia abdominal coinciden en la identificación del pequeño y del grande. El PAL se correlacionó con la circunferencia abdominal del tercer trimestre y con el peso al nacer; presentando mayor frecuencia de valores en el tercer tertil para los nacimientos grandes. Conclusiones: La circunferencia abdominal fue el parámetro biométrico con mayor coincidencia con la condición trófica al nacer, la que se asoció con valores en el tercer tertil del PAL para la detección de nacimientos grandes, relacionándose el fenotipo normopeso metabólicamente obeso con el crecimiento fetal por exceso.

Background: Maternal nutritional status disorders are usually related to fetal growth deviations, which can be detected by fetal biophysical parameters and identify the possible trophic condition at birth. Objective: To determine the possible relationship between fetal biometric parameters, the birth trophic state and lipid accumulation product. Methodology: A cross-sectional study was conducted at the Chiqui Gómez Lubian Polyclinic in Santa Clara municipality, during 2019, in a population of 253 normal-weight pregnant women who were apparently healthy at the beginning of their gestation. The non-probability sample was made up of 144 pregnant women. Study variables were: lipid accumulation product, fetal biometry and trophic condition at birth. Theoretical, empirical and statistical methods were used. Results: In the second trimester, none of the biometric parameters matched the condition at birth as a small child, while in the large one the head and abdominal circumferences matched. In the third trimester, femoral length and abdominal circumference coincide in identifying the small one and the large one. LAP correlated with third trimester abdominal circumference and birth weight, presenting higher frequency of values in the third tertile for large births. Conclusions: Abdominal circumference was the biometric parameter with the highest coincidence with trophic condition at birth, associated with values in the third tertile of the LAP for detecting large births, relating the metabolically obese normal weight phenotype with excessive fetal growth.

Dependence of radioactive iodine-131 capture by the lacrimal ducts on the tear production level

Purpose: Secondary acquired lacrimal duct obstruction (SALDO) is one of the complications of radioiodine therapy. SALDO is formed a few months after therapy if there is a sufficient uptake of radioactive iodine by the nasolacrimal duct. To date, risk factors leading to SALDO are unclear. The objective was to determine the correlation between the tear production level and radioactive iodine?131 uptake in the lacrimal ducts.Methods: Basal and reflex tear production was studied in 64 eyes prior to the therapy with radioactive iodine?131 after drug?induced hypothyroidism. The condition of the ocular surface was assessed using the Ocular Surface Disease Index (OSDI) questionnaire. Seventy?two hours after the radioactive iodine therapy, scintigraphy was performed, which determined the presence or absence of iodine?131 in the lacrimal ducts. T?statistics and the Mann–Whitney criterion were used to identify the differences between the groups. The differences were considered significant at P ? 0.05. The current tear production level in patients receiving radioiodine therapy was determined using a mathematical model. Results: A statistically significant difference between the basal (p = 0.044) and reflex (p = 0.015) tear production levels was found in cases with and without iodine?131 uptake by the lacrimal ducts. The probable current tear production level corresponds to the sum of basal and 10–20% of reflex tear production. The uptake of iodine?131 was found regardless of the OSDI results.Conclusion: The probability of iodine?131 uptake by the lacrimal ducts rises as the tear production level increases.

Percentiles de peso, talla e índice de masa corporal de escolares de Mendoza. Comparación con la referencia de la Organización Mundial de la Salud / Body mass index, weight, and height percentiles in school-aged children from Mendoza. A comparison with the WHO reference

Introducción. La Organización Mundial de la Salud (OMS) recomienda el uso de tablas de referencia para monitorear el crecimiento y estado nutricional de niños, niñas y adolescentes. El peso corporal, la talla y el índice de masa corporal (IMC) son las variables más utilizadas. El presente trabajo tiene como objetivos estimar los percentiles de peso, talla e IMC de escolares (2009-2011) residentes en el departamento San Rafael (Mendoza) y compararlos con la referencia internacional de la Organización Mundial de la Salud, a fin de establecer su pertinencia para la evaluación del crecimiento y estado nutricional de dicha población. Población y métodos. Se realizó un estudio antropométrico transversal en 3448 escolares de entre 4,00 y 13,49 años de edad. Se utilizó el programa LMS ChartMarker Pro para calcular los valores percentilares de peso/edad, talla/edad e IMC/edad, por sexo y edad, y se compararon con las curvas de la OMS. Además, se calcularon diferencias porcentuales (D%) para estimar las diferencias y su significación estadística mediante prueba de Wilcoxon. Resultados. La población de San Rafael mostró, en varones y mujeres, valores percentilares superiores de peso e IMC (D% ≈7 % y 9 %, respectivamente), y menores de talla (D% ≈0,8 %) que los de la OMS (p <0,05). Conclusión. Las diferencias encontradas alertan sobre el empleo de la referencia OMS en la población escolar de San Rafael, ya que sobreestimaría las prevalencias de sobrepeso, obesidad y desnutrición crónica, y subestimaría la de desnutrición aguda y global. Esta situación resalta la importancia de contar con una referencia local.

Introduction. The World Health Organization (WHO) recommends the use of reference tables to monitor the growth pattern and nutritional status of children and adolescents. Body mass index (BMI), weight, and height are the most commonly used variables. The objective of this study was to estimate the BMI, weight, and height percentiles for school-aged children (2009-2011) living in the department of San Rafael (Mendoza) and compare them to the international World Health Organization reference to establish their relevance for the evaluation of the growth pattern and nutritional status of this population. Population and methods. A cross-sectional anthropometric study was conducted in 3448 school-aged children aged 4.00 to 13.49 years. The LMS ChartMarker Pro software was used to estimate the BMI- for-age, weight-for-age, and height-for-age percentiles, by sex and age, and they were compared with the WHO curves. Besides, percentage differences (%D) were calculated to estimate the differences and their statistical significance using the Wilcoxon test. Results. The population of boys and girls in San Rafael showed higher weight and BMI (%D ≈ 7% and 9%, respectively) percentiles, and lower height (%D ≈ 0.8%) values than WHO reference (p < 0.05). Conclusion. The differences found warn about the use of the WHO reference in the school-aged population of San Rafael since it would overestimate the prevalence of overweight, obesity, and chronic malnutrition and underestimate the prevalence of acute and global malnutrition. This situation highlights the importance of having a local reference resource

Age estimation of Russian individuals by teeth using the London Atlas / Análise da estimativa de idade em indivíduos russos utilizando a metodologia London Atlas

Knowing an individual's age is necessary for several situations, both in the living and the deceased. The London Atlas uses dental development and eruption to estimate age. Testing the method in different populations is necessary to assess its performance. This study aimed to assess the performance of the London Atlas method in a Russian sample using panoramic radiographs. A sample of 703 panoramic radiographs of Russian individuals (n = 405 females, 57.61% and n = 298 males, 42.39%) with ages between 8 and 23 years were analyzed. The results showed overestimation in individuals from 8 to 14 years and underestimation from 15 to 23 years. The mean difference between estimated and chronological ages did not exceed 0.7 years among individuals with ages below 19 years. The difference increased to over three years in individuals from 20 to 23 years. Statistically significant differences were found between females and males between 17 and 18 years (p<0.05). The London Atlas is suitable for Russian children and adolescents aged between 8 and 19 years; however, it showed unsatisfactory results for application in individuals over 20 years (AU).

Conhecer a idade de um indivíduo, vivo ou morto, é essencial em diversas situações. O método London Atlas utiliza desenvolvimento e erupção dentais para estimar a idade. Testar o método em diferentes populações é importante para avaliar sua performance. Esse estudo objetivou analisar o desempenho do London Atlas em uma amostra de origem russa, utilizando radiografias panorâmicas. Uma amostra de 703 indivíduos russos (n = 405 mulheres, 57,61% e n = 298 homens, 42,39%), com idades entre 8 e 23 anos foram analisadas. Resultados obtidos mostram uma superestimação em indivíduos de 8 a 14 anos e subestimação nos grupos de 15 a 23 anos. A diferença média entre idades estimadas e reais não excederam o valor de 0,7 anos nos indivíduos com idade abaixo de 19 anos. Essa diferença aumentou em até três anos em indivíduos de 20 a 23 anos. Diferenças estatisticamente significantes foram encontradas entre homens e mulheres com 17 e 18 anos (p<0,05). O London Atlas é adequado para crianças e adolescentes de origem russa, com idades de 8 a 19 anos. No entanto, observou-se resultados insatisfatórios para sua aplicação em indivíduos acima de 20 anos (AU).

Canalización del crecimiento entre los 2 y los 5 años en niños aparentemente sanos con talla baja a los 2 años / Canalization of growth between 2 and 5 years of age in apparently healthy children with short stature at age 2 years

Introducción. El tamaño del recién nacido se asocia a condiciones intrauterinas. El potencial genético se expresa más tarde; la canalización del crecimiento se describe clásicamente hasta los 24 meses. Objetivo. Describir la canalización del crecimiento entre los 2 y los 5 años en niños aparentemente sanos con talla baja a los 2 años. Población y métodos. Estudio de cohorte retrospectiva. Se incluyeron niños seguidos en un hospital universitario de comunidad entre 2003 y 2019, con puntaje Z de talla menor a -2 DE para edad y sexo a los 2 años. Se excluyeron los nacidos prematuros, con bajo peso y con enfermedades crónicas. Se evaluó la trayectoria de crecimiento. Se definió canalización como la adquisición de talla normal para la población general. Resultados. Se incluyeron 64 niños, de los cuales 37 (58 %) presentaron canalización del crecimiento a los 5 años (20 a los 3 años, 8 a los 4 años, y 9 a los 5 años). La velocidad de crecimiento a los 3 y a los 5 años fue significativamente mayor en los que canalizaron en comparación con los que no lo hicieron; hubo una tendencia similar a los 4 años. De los 27 niños con talla baja a los 5 años, 25 tuvieron al menos un registro de velocidad de crecimiento anual menor al percentil 25. Conclusiones. La mayoría de los niños aparentemente sanos con baja talla a los 2 años alcanzan una talla normal a los 5 años. La velocidad de crecimiento anual permite detectar a los niños con riesgo de no canalizar.

Introduction. Newborn size is associated with intrauterine conditions. Genetic potential is expressed later; the canalization of growth is typically described up to 24 months of age. Objective. To describe the canalization of growth between 2 and 5 years of age in apparently healthy children with short stature at age 2 years. Population and methods. Retrospective, cohort study. Children seen at a community teaching hospital between 2003 and 2019, who had a Z-score for height below -2 SDs for age and sex at age 2 years were included. Infants born preterm, with a low birth weight, and chronic conditions were excluded. Growth patterns were assessed. Canalization was defined as reaching a normal stature for the general population. Results. Sixty-four children were included; 37 (58%) showed canalization of growth at 5 years old (20 at 3 years, 8 at 4 years, and 9 at 5 years). The growth rate at 3 and 5 years of age was significantly higher among those who showed canalization compared to those who did not; a similar trend was observed at 4 years of age. Among 27 children with short stature at 5 years of age, 25 had at least 1 annual growth velocity below the 25th centile. Conclusions. Most apparently healthy children with short stature at 2 years old reached a normal stature at 5 years old. The annual growth velocity allows to detect children at risk of not showing canalization.

Incorporación a las estadísticas oficiales del Municipio de Pila de indicadores positivos de salud infantil: proyecto CREDEPILA / Incorporation of positive child health indicators to the official statistics of the Municipality of Pila: CREDEPILA project

RESUMEN INTRODUCCIÓN: El municipio bonaerense de Pila carecía de indicadores adecuados para monitorear la salud infantil de su población. El objetivo fue incorporar indicadores positivos de crecimiento físico y desarrollo psicomotor en niños de 0 a 5,99 años. MÉTODOS: Se convocó a toda la población objetivo (con consentimiento parental) a los jardines y centros de atención primaria. Personal capacitado midió peso, estaturalongitud corporal y administró 13 pautas de desarrollo de la Referencia Nacional (RN). Las medianas de datos antropométricos se obtuvieron con el método LMS; la edad de cumplimiento de pautas se estimó con regresión logística y el ajuste, con el test de Hosmer-Lemeshow. El índice de desarrollo (ID) se calculó con una regresión lineal entre las diferencias entre las edades de cumplimiento de los niños con las de la RN, y las edades de la RN. RESULTADOS: De un total de 321 niños, se evaluó a 307 (95,6% del total; 169 niñas). Las curvas de estatura fueron similares a las de la Organización Mundial de la Salud y a las argentinas actualizadas (los puntajes "z" no difirieron significativamente de cero); las de peso e índice de masa corporal mostraron un moderado sobrepeso: z= 0,38±0,07 de desvío estándar. No hubo diferencias significativas entre sexos. Con las 6 pautas que mostraron un ajuste adecuado, el ID fue 89. DISCUSIÓN: El método se implementó con éxito. Pila cuenta ahora con una línea de base para el monitoreo anual de la salud infantil.

ABSTRACT INTRODUCTION: The Buenos Aires municipality of Pila lacked adequate indicators to monitor child health in the population. The objective was to incorporate positive indicators based on physical growth and psychomotor development in children aged 0 to 5.99 years. METHODS: The entire target population was summoned to kindergartens and primary care centers (with parental consent). Trained health personnel measured weight, supine length/height and administered 13 developmental items taken from the National Reference (NR). Medians of anthropometric data were obtained with LMS method; the age of attainment of items was estimated with logistic regression and the fit was assessed with the Hosmer-Lemeshow test. Developmental index (DI) was calculated with linear regression of differences between children's attainment ages and those of the NR, and the ages of the NR. RESULTS: Of 321 children, 307 (95.6% of the total; 169 girls) were evaluated. Height curves were similar to those of the World Health Organization and updated Argentine curves (z-scores did not significantly differ from zero); weight and body mass index curves showed moderate overweight: z = 0.38±0.07 standard deviation. No significant sex differences were found. Based on the 6 items that showed a good fit, the DI was 89. DISCUSSION: The method was successfully implemented. Pila has now a baseline for annual monitoring of children's health.

Avaliação do crescimento e desenvolvimento infantil e fatores de risco de um município que integra uma universidade brasileira de cunho internacional / Evaluation of childhood growth and development and risk factors of a municipality that is part of an international brazilian university / Evaluación de los factores de crecimiento y desarrollo infantil y de riesgo de un municipio que forma parte de una universidad brasileña internacional

Fatores de risco, incluindo os de cunho materno, interferem no crescimento e desenvolvimento infantil. Nesse sentido, o conhecimento desses fatores e avaliação ade- quada desses processos são necessários para articulação de estratégias preventivas de transtornos futuros. Assim, o estudo visou investigar o crescimento e desenvolvimento de crianças atendidas em consulta de puericultura em unidades básicas de saúde de um mu- nicípio cearense, que integra uma universidade brasileira de cunho internacional, e seus fatores de risco. Trata-se de estudo observacional, analítico, transversal e de abordagem quantitativa, conduzido com crianças e suas mães no Centro de Saúde de Acarape e Posto de Saúde São Benedito (Acarape ­ CE), no período de fevereiro a julho de 2021. Após consentimento, as mães preencheram um questionário, seguido de avaliação do cresci- mento e desenvolvimento das crianças. Os dados obtidos foram analisados. Das 70 crian- ças, 50,00% (n = 17) e 51,43% (n = 18) dos meninos e meninas tinham baixa estatura para idade, respectivamente. Para o desenvolvimento psicossocial, dos 284 testes condu- zidos, 86,27% (n = 245) foram realizados em plenitude pelas crianças. Observou-se as- sociação significativa entre a gestante ter concebido o filho com, no mínimo, 9 meses de período gestacional e esse apresentar relação Peso/Idade adequada e Estatura/Idade ina- dequada. Houve associação significativa entre a criança não ingerir refresco em pó e apre- sentar relação Peso/Idade adequada. Conclui-se que as crianças tinham idade gestacional adequada e apresentavam estado nutricional apropriado, apesar da baixa estatura para idade. Manifestavam desenvolvimento psicossocial, de linguagem e físico normais. Sobre os fatores de risco, esses envolveram os de cunho materno e o consumo de alimentos cariogênicos.

Risk factors, including maternal ones, interfere with child growth and de- velopment. In this sense, knowledge of these factors and adequate evaluation of these processes are necessary to articulate preventive strategies for future disorders. Thus, the study aimed to investigate the growth and development of children seen in childcare con- sultations in primary health units in Ceará, part of a Brazilian university of international character, and their risk factors. This is an observational, analytical, cross-sectional study with a quantitative approach, conducted with children and their mothers at the Acarape Health Center and São Benedito Health Center (Acarape ­ CE), from February to July 2021. After consent, the mothers completed a questionnaire, followed by an assessment of the children's growth and development. The data obtained were analyzed. Of the 70 children, 50.00% (n = 17) and 51.43% (n = 18) of the boys and girls were short for their age, respectively. Of the 284 tests conducted for psychosocial development, 86.27% (n = 245) were entirely performed by the children. A significant association was observed between the pregnant woman having conceived her child at least nine months of gestation and having an adequate Weight/Age and Height/Age ratio. There was a significant asso- ciation between the child not ingesting powdered soft drinks and having an appropriate Weight/Age ratio. It was concluded that the children had an adequate gestational age and had an appropriate nutritional status, despite their low height for their age. They showed normal psychosocial, language, and physical development. The risk factors involved those of mother nature and the consumption of cariogenic foods.

Los factores de riesgo, incluidos los maternos, interfieren en el crecimiento y desarrollo infantil. En este sentido, el conocimiento de estos factores y la evaluación adecuada de estos procesos son necesarios para articular estrategias preventivas de futu- ros trastornos. Así, el estudio tuvo como objetivo investigar el crecimiento y desarrollo de niños atendidos en consultas de puericultura en unidades básicas de salud de un muni- cipio de Ceará, que forma parte de una universidad brasileña de carácter internacional, y sus factores de riesgo. Se trata de un estudio observacional, analítico, transversal, con enfoque cuantitativo, realizado con niños y sus madres en el Centro de Salud de Acarape y el Centro de Salud São Benedito (Acarape ­ CE), de febrero a julio de 2021. Después del consentimiento, las madres completaron un cuestionario, seguido de una evaluación del crecimiento y desarrollo de los niños. Los datos obtenidos fueron analizados. De los 70 niños, el 50,00% (n = 17) y el 51,43% (n = 18) de los niños y niñas eran bajos para su edad, respectivamente. Para el desarrollo psicosocial, de las 284 pruebas realizadas, el 86,27% (n = 245) fueron realizadas íntegramente por los niños.

Correlation between cleft width and dental arch symmetry in cleft lip and palate: a longitudinal study

Abstract This study aimed to evaluate the influence of cleft width on dental arch symmetry of children with unilateral cleft lip and palate. Forty-one children were subjected to impression preoperatively (T1; mean age = 0.31 ± 0.07 years) and postoperatively (T2; mean age = 6 .73 ± 1.02 years). Eighty-two digitized dental casts were analyzed by stereophotogrammetry software. The cleft palate width was measured in the anterior (P-P'), middle (M-M'), and posterior (U-U') regions. Also, the following measurements were obtained: anterior intersegment (I-C') and intrasegment (I-C); total intersegment (I-T') and intrasegment (I-T); cleft-side (C'-T') and non-cleft-side (C-T) canine tuberosity. Paired t test and Pearson correlation coefficient were applied (α = 5%). Cleft width had the following means: 10.16 (± 3.46) mm for P-P', 12.45 (± 3.00) mm for M-M', and 12.57 (± 2.71) mm for U-U'. In the longitudinal analysis, I-C' had a significant reduction, while the other measurements significantly increased (p < 0.001). Asymmetry was verified in the following analyses at T1: I-C' vs. I-C and I-T' vs. I-T (p < 0.001); at T2, only in I-C' vs. I-C (p < 0.001). At T1, P-P' vs. I-C' (r = 0.722 and p < 0.001), P-P' vs. I-T' (r = 0.593 and p < 0.001), M-M' vs. I-C' (r = 0.620 and p < 0.001), and M-M' vs. I-T' (r = 0.327 and p < 0.05) showed a positive and significant correlation. At T2, there was a correlation between M-M' and I-C' (r = 0.377 and p < 0.05). In conclusion, the anterior and middle cleft widths influenced palatal asymmetry in the first months of life, while middle width influenced residual asymmetry.

A longitudinal study on association between puberty development and thyroid function of school aged girls in Minhang District, Shanghai / 中国学校卫生

Objective@#To observe the association between puberty development and thyroid function among school-aged girls in Minhang District of Shanghai, in order to explore the effect of puberty development on thyroid function. @*Methods@#The study was based on a cohort of adolescent girls recruited in iodine-suitable areas of Minhang District, and the baseline and follow-up survey have been carried out from January to March 2019. The method of phased cluster sampling was used to select one junior high school in the east, south, north and middle of Minhang District, Shanghai, respectively. Finally, 464 new junior high school girls were included in the Cohort study for physical examination, and girls were followed up from January to March 2021. The Puberty Development Scale (PDS) was used to assess the stage of puberty. Serum thyroid stimulating hormone (TSH), free triiodothyronine (FT3), and free thyroxine (FT4) were determined for each participant. Thyroid homeostasis structure parameters (THSPs) was calculated. Changes of Thyroid hormones at baseline and follow-up were compared by Wilcoxon signed rank sum test. Multiple linear regression analyses were used to evaluate the associations of thyroid hormones (THs) and THSPs changes with pubertal develepment.@*Results@#Serum TSH levels of female studentds decreased significantly, while their FT3 and FT4 levels increased significantly during the study period ( Z=-10.53, -4.71, -12.46, P <0.01). In multiple linear regression analysis after adjustment for co-variables (including baseline age, change of BMI and waist circumference), FT4 and thyroid feedback quantile-based index (TFQI) in the higher puberty category scores changes (△PCS) group were further reduced compared with those in the low △PCS group ( β =-0.66, -0.55 ). Compared to the late puberty at baseline and follow-up (BLFL) group, FT4 and TFQI showed higher decline in the pre-puberty at baseline and late puberty at follow-up (BPFL) group with the pre-puberty at baseline and end of puberty at follow-up (BPFT) group ( β =-0.55, -0.44)( P <0.05). There were no association of △TSH, △FT3, △FT4/FT3 and TSH index changes (△TSHI) with △PCS or the puberty pattern.@*Conclusion@#Serum TSH decreases while serum FT3 and FT4 increase among girls during puberty. Both the initial stage and the velocity of pubertal development are related to thyroid hormone fluctuations.

Accuracy of bone age assessment system based on deep learning in children with abnormal growth and development / 中华放射学杂志

Objective:To explore the accuracy of artificial intelligence (AI) system based on deep learning in evaluating bone age of children with abnormal growth and development.Methods:The positive X-ray films of the left wrist of children with abnormal growth and development who were treated at the Affiliated Hospital of Guizhou Medical University from January 2020 to December 2021 were collected retrospectively. A total of 717 children were collected, including 266 males and 451 females, aged 2-18 (11±3) years. Based on Tanner Whitehouse 3 (TW 3)-RUS (radius, ulna, short bone) and TW3-Carpal (carpal bone) method, bone age was measured by 3 senior radiologists, and the mean value was taken as reference standard. The bone ages were independently evaluated by the AI system (Dr.Wise bone age prediction software) and two junior radiologists (physicians 1 and 2). The accuracy within 0.5 year, the accuracy within 1 year, the mean absolute error (MAE) and the root mean square error (RMSE) between the evaluation results and the reference standard were analyzed. Paired sample t-test was used to compare MAE between AI system and junior physicians. Intraclass correlation coefficient (ICC) was used to evaluate the consistency between AI system, junior physician and reference standard. The Bland-Altman diagram was drawn and the 95% consistency limit was calculated between AI system and reference standard. Results:For TW3-RUS bone age, compared with the reference standard, the accuracy within 0.5 year of AI system, physician 1 and physician 2 was 75.3% (540/717), 62.1% (445/717) and 66.2% (475/717), respectively. The accuracy within 1 year was 96.9% (695/717), 86.3% (619/717) and 89.1% (639/717), respectively. MAE was 0.360, 0.565 and 0.496 years, and RMSE was 0.469, 0.634 and 0.572 years, respectively. For TW3-Carpal bone age, compared with the reference standard, the accuracy within 0.5 year of AI system, physician 1 and physician 2 was 80.9% (580/717), 65.1% (467/717) and 71.7% (514/717), respectively. The accuracy within 1 year was 96.0% (688/717), 87.3% (626/717) and 90.4% (648/717), respectively. MAE was 0.330, 0.527 and 0.455 years, and RMSE was 0.458, 0.612, 0.538 years, respectively. Based on TW3-RUS and TW3-Carpal bone age, the MAE of AI system were lower than those of physician 1 and physician 2, and the differences were statistically significant ( P all<0.001). The evaluation results of AI, physician 1 and physician 2 were in good agreement with the reference standard (ICC all>0.950). The Bland-Altman analysis showed that the 95% agreement limits of AI system for assessing TW3-RUS and TW3-Carpal bone age were -0.75-1.02 years and-0.86-0.91 years, respectively. Conclusion:The accuracy of AI system in evaluating the bone age of children with abnormal growth and development is close to that of senior doctors, better than that of junior doctors, and in good agreement with senior doctors.

Objective@#To examine the effects of high intensity interval training (HIIT) on body composition and cardiorespiratory fitness of obese primary school students, so as to provide a theoretical basis and practical reference for HIIT exercise prescription in schools.@*Methods@#From August to December 2022, 25 obese children [age:(11.0±0.4)years, BMI:(23.3±0.8)kg/m 2] from a primary school in Shenzhen were recruited and divided into an exercise group ( n =13) and a control group ( n =12). After 12 weeks of exercise intervention [The durations of load period and intermittent period were 15 s, load exercise intensity was 100% maximal aerobic speed (MAS), and intermittent exercise intensity was 50% MAS, each time there were 2 groups× 8 rounds, and the rest between groups was 2 minutes, totaling 10 minutes, and 20 meter shuttle run test (20 m-SRT) was performed once every 4 weeks to adjust and update MAS], the changes in body composition and cardio respiratory fitness indexes of obese subjects before and after the intervention were compared.@*Results@#After the intervention, body weight, BMI, body fat, body fat percentage, and visceral adipose tissue area of obese subjects in the exercise group decreased from (55.6±6.2)kg, (22.7±0.6)kg/m 2, (41.8±6.9)kg, ( 23.4± 5.5)% and (102.4±39.0)cm 2 to (52.3±5.8)kg, (21.1±0.8)kg/m 2, (38.6±6.3)kg, (20.2±4.5)% and (84.2±26.9)cm 2, respectively( t =8.73, 10.96, 7.02, 4.92, 4.95, P <0.05). SBP decreased from (115.4±9.7)mmHg to (112.3±8.7)mmHg ( t = 2.96 , P <0.05). The content of skeletal muscle, 20 m-SRT and VO 2max increased from (21.3±5.3)kg, (21.6±4.9) times and (39.4±2.0)mL/(kg ·min) to (21.8±5.2)kg, (31.4±6.3)times and (43.6±2.6)mL/(kg ·min), respectively ( t =-3.33, -8.37, -10.56 , P <0.05).@*Conclusions@#HIIT is an effective way to improve the body composition and cardiorespiratory fitness of obese primary school students. It is recommended that schools with the necessary conditions use this method as an intervention measure to help reduce weight and improve cardiovascular health among obese students.

Growth and intelligence development among a cohort of low birth weight infants / 中国学校卫生

Objective@#To explore growth and intelligence development of low birth weight infants (LBWI) at 24 and 36 months of age, so as to provide reference for early monitoring and intervention of the development of LBWI.@*Methods@#A total of 100 LBWI born and managed in Hefei Maternal and Child Health Care Institution were selected from 2012 October 1 to 2015 December 30, and 99 normal birth weight infants (NBWI) under child health management in the same sitinstitution were selected as controls. According a prospective cohort study method, and based on the establishment of a cohort and monitoring of childhood growth and development, a unified method was used to longitudinally follow up and observe the physical fitness of two groups of infants at the determined time points. The development of LBWI and NBWI at 24 and 36 months of age was surveyed using the Gesell Development Scale.@*Results@#Weight, length and head circumference of LBWI children at the age of 15-36 months were significantly lower than those of NBWI children ( P <0.05). In addition, 117 children (43.98%) completed the full assessment of intelligent development scale, including 62 LBWI and 55 NBWI. The scores of Gesell in NBWI group was higher than that in LBWI group at 24 and 36 months of age, including adaptability, gross motor, fine metor skills, language and personal social functions ( t =-4.17, -3.82, -3.21 , -3.03, -2.61; -4.23, -3.16, -3.07, -3.13, -3.99, P <0.05). Multivariate linear regression analysis found that birth weight was positively correlated with adaptability, gross motor, fine motor skills, language functions at 24 and 36 months of age and personal social function at 36 months of age ( β =0.004, 0.010; 0.003, 0.008; 0.003, 0.007; 0.004, 0.009; 0.011, P ＜0.05).@*Conclusion@#The growth and development of LBWI children are significantly delayed compared to NBWI children. The scores of LBWI children are lower than those of NBWI children in all functional areas. Weight is the main factor affecting children s intellectual development. Early monitoring and intervention of low birth weight infants should be carried out to avoid or mitigate adverse consequences.

The isochronous substitution effect of 24 hour activity behavior on physical health of college students / 中国学校卫生

Objective@#An isochronous substitution model was established to explore the association and substitution effect between college students 24 hour activity behavior and physical health, so as to provide specific activity behavior suggestions for college students to improve their physical health.@*Methods@#A stratified random cluster sampling method was used to conduct physical fitness tests and 24 hour activity behavior surveys among 2 794 college students in 12 colleges and universities in Tianjin.Time spent on sedentary behavior(SB), light intensity physical activity(LPA), moderate to vigorous physical activity(MVPA) and sleep(SLP) time. The isochronous method of components was used to explore the relationship between 24 h activity behavior and physical health.@*Results@#Except for 50 m running, MVPA was negatively correlated with BMI Z ( β =-0.62, P <0.05), but positively correlated with other physical fitness indexes ( β =0.34~274.23, P <0.05). LPA was not associated with lung capacity, sitting forward flexion and 50 m running, and negatively correlated with other physical fitness indexes ( β =-14.30- -0.19, P <0.05). SB was negatively correlated with most physical fitness indexes ( β =-11.57- -0.33, P <0.05), but positively correlated with BMI Z ( β =0.45, P < 0.05 ). In addition to lung capacity, SLP was positively correlated with BMI Z , total physical fitness score,1 minute sit-ups, pull ups, 800/1 000 m running, sitting forward flexion, and 50 m running ( β =0.27-11.21, P <0.05), but negatively correlated with long jump ( β =-0.10, P <0.05）. Isochronous substitution showed that the adverse effects of 30 min/d SB and LPA substitution of MVPA were much greater than the beneficial effects of MVPA substitution for corresponding behaviors (total physical score: SB, -0.58 vs 0.47 points; LPA, -0.50 vs 0.38 points).@*Conclusion@#MVPA and SLP have been found to have a positive effect on physical fitness among college students. Therefore, in the process of improving the physical health of college students, ensuring adequate sleep, improving MVPA and reducing SB as much as possible may be one of the effective methods.
