Thoracic proportions in children without scoliosis

Purpose Scoliosis is a condition of abnormal growth resulting in 3D deformity of both the spine and thoracic cage. The aim of this study is to use chest radiographs of healthy children to define normal thoracic proportions so as to provide a useful normal reference range against which children with spinal deformity can be compared. Methods Three independent reviewers assessed posteroanterior and lateral chest radiographs of 184 normal children aged between two and 15 years. Duplicate assessments were undertaken by all three raters on 36 of these radiographs. We measured the T1 to T12 length, sternal length, chest depth at T6, chest width at T3, chest width at T6 and maximum chest width. Ratios of thoracic dimensions were calculated to define the normal proportions of the thorax. Inter- and intra-rater variance was estimated for all dimensions and dimension ratios. Results The intra-rater and inter-rater reliability was excellent with intra-class-correlation coefficients values > 80% and both intra- and inter-rater coefficients of variance < 9% for all parameters. All measured dimensions of the thorax and spine progressed linearly with respect to age. The mean proportions of T1 to 12 length of the sternal length, chest depth at T6, chest width at T3, chest width at T6 and maximum chest width were 0.5, 0.4, 0.7, 0.9 and 1.0, respectively. Conclusion It is possible to accurately and reproducibly measure the dimensions of the thoracic cage and spine on plain film radiology. The ratios of T1 to T12 length with respect to sternal length, chest depth at T6, chest width at T3, chest width at T6 and maximum chest remain constant with increasing age. Thoracic dimensions in children progress linearly with increasing age. Level of Evidence V

Abstract Purpose Appetitive traits in adults and their associations with weight can be measured using the Adult Eating Behaviour Questionnaire (AEBQ). The aim of this study was to confirm the factor structure of the Spanish AEBQ (AEBQ-Esp) in a Mexican sample and explore associations between the eight traits with body mass index (BMI). Method A sample of 1023 adults, mean age of 36.8 ± 12.8 years, was recruited from Guadalajara, Mexico. Researchers weighed and measured participants, and they completed the AEBQ-Esp either online or in paper format and reported sociodemographic data. To test two alternative factor structures (eight factors including Hunger; seven factors excluding Hunger), confirmatory factor analysis (CFA) was used. Internal reliability was assessed using Cronbach’s alpha; test–retest reliability was assessed using intra-class correlation coefficients. Multivariate linear regressions were used to test for associations between the AEBQ subscales and BMI, adjusted for age, sex, format of AEBQ responses, education, marital and employment status. Results A seven-factor structure was the best model fit using CFA, excluding the Hunger subscale but similar to the original AEBQ. Internal reliability was good for all subscales (Cronbach’s α = 0.70–0.86), and the intra-class correlation coefficient (0.70–0.91) reflected good test–retest reliability. In the fully adjusted models, Satiety Responsiveness [β = − 0.61; (− 1.01, − 0.21)] and Slowness in Eating [β = − 0.70; (− 1.01, − 0.39)] were negatively associated with BMI, and Emotional Over-Eating [β = 0.94; (0.62, 1.27)] was positively associated with BMI. Conclusions The AEBQ-Esp (excluding Hunger) appears to be a valid and reliable psychometric questionnaire for measuring appetitive traits in a Mexican Spanish-speaking population. Some traits appear to be associated with BMI in adulthood and warrant further exploration. Level of evidence Level III evidence obtained from well-designed cohort or case–control analytic studies. Although this was just an observational study, it was well designed and provided new evidence.

Purpose Early diagnosis and prevention of lateral growth disturbance of the capital femoral epiphysis is challenging after treatment for developmental dysplasia of the hip (DDH). The aim of the study was to evaluate the radiographic changes of the Alsberg angle (AA) in normal children and those with DDH, and to assess the role of AA as a potential predictor of lateral growth disturbance of the capital femoral epiphysis. Methods AA was measured on the anterior-posterior pelvic radiographs of 1000 normal children ranging in age from one to ten years and in 66 children (92 hips) with DDH treated by closed reduction (CR). A comparative analysis was performed. Results In the normal children, mean AA decreased linearly with age, from 76° at age one year to 65° at age ten years, irrespective of gender and laterality. In children with DDH, the average AA was 81.5°(sd 3.9°; 74° to 87°) prior to CR; it was 75.9° (sd 4.5°; 68° to 83°) in normal children of the same age (p < 0.001). Among the 42 children (64 hips) with successfully and uneventfully treated DDH, AA reached normal values between the ages of five and six years. In contrast, children with lateral growth disturbance of the proximal femur physis (24 children, 28 hips) showed significantly higher AA values in comparison with the age-matched controls. Conclusion In DDH patients with successful CR, AA could be expected to match normal values in children between the ages of five and six years. On the other hand, AA can be used as an early predictor for lateral growth disturbance of the capital femoral epiphysis. Level of Evidence Level III

Background and Objectives: The techniques directed to the cranial field in osteopathy are the most questioned due to the lack of scientific evidence. In osteopathic practice, manual palpation is essential and, therefore, measuring reliability is fundamental. The objective of this study is to assess the precision and objectification of an educational model in cranial osteopathy based on experience. Materials and Methods: A reliability study was conducted in a cadaver skull where a strain gauge was placed on the sphenobasilar synchondrosis (SBS) of the base of the skull. Three cranial osteopathic techniques (lateral compression, anteroposterior compression, and compression maneuver of the mastoids) were performed 25 times by osteopaths with different degrees of experience (5–10 years, 1–5 years, <1 year). Measurements were computed for each of the three techniques of each group in comparison with the osteopath with >15 years of experience. Data were analyzed to check for inter- and intra-observer reliability using intra-class correlation coefficients (ICC). Results: Reliability in osteopaths with 5–10 years’ experience (observer 1 and observer 2) performing all three techniques was higher (p < 0.001) than the osteopath with >15 years’ experience. Little or no reliability were observed in osteopaths with less experience. Conclusions: The experience of the osteopaths determines the reliability and effectiveness of the cranial techniques, a fundamental part in objectifying these techniques. This model can help implement objective training in cranial osteopathy formation.

Abstract Background The antistreptolysins O “ASLO” are anti streptococcal antibodies directed against streptolysin O. The assay of ASLO can provide proof of infection of streptococcal origin. However, it cannot confirm the presence of RAA or the degree of severity of the disease. A level of ASLO less than or equal to a critical threshold of 200 IU/ml is considered normal in children. Several factors influence the ASLO title and therefore their standard rate such as age, geographic location and seasonal variation. The objective of this study is to determine the upper normal limit (ULN) of ASLO in healthy children with angina or RAA at the CHU Hassan II of Fez in Morocco. Methods This is a cross-sectional study carried out from January 2016 to July 2019 in the cardiopediatric unit of CHU Hassan II and the Anarjiss health center in Fez. Patients below 18 years of age were included in this study. The children are classified into 3 groups: group 1: 152 children with RAA and who are diagnosed according to the modified Jones criteria, group 2: 177 children with angina, group 3: 157 healthy children who did not have an RAA, a history of recurrent or recent pharyngitis. Patient data is collected on operating sheets. Statistical analysis was performed using SPSS v 21 software. To establish a normal upper limit for ASLOs, the 90 percentile was used as it is a value below which at least 90% of cases studied in each group. Results The most common age group in the 3 groups is the age group between 5 and 15 years old. The frequency of children of urban origin is greater than that of rural origin in all the groups studied. The ULN is 421.4U/ml in the group of normal children, 641.95 U/ml in the RAA group and 561.8 U/ml in the group of children with pharyngitis. The study of changes in ASLO rates over time shows that they increase significantly in angina and tend to decrease in RAA. The LSN of ASLOs by gender shows that it is higher for boys than for girls. The ULN according to the residence shows that it is higher in urban areas. As well as the LSN of ASLO according to the season shows that it is higher in the cold period, especially in winter and spring (P < 0.001). With regard to age, the ULN of ASLOs is higher in the 5–15 age group. Conclusion In this study, it can be concluded that an ASLO level less than or equal to 400 U/ml is the critical threshold in a normal child, while an ASLO level >400 U/ml is considered pathological in children. children in Morocco.

Abstract Study Objectives Within-subject stability of certain sleep features across multiple nights is thought to reflect the trait-like behavior of sleep. However, to be considered a trait, a parameter must be both stable and robust. Here, we examined the stability (i.e., across the same sleep opportunity periods) and robustness (i.e., across sleep opportunity periods that varied in duration and timing) of different sleep parameters. Methods Sixty-eight military personnel (14 W) spent 5 nights in the sleep laboratory during a simulated military operational stress protocol. After an adaptation night, participants had an 8-hour sleep opportunity (23:00–07:00) followed by 2 consecutive nights of sleep restriction and disruption which included two 2-hour sleep opportunities (01:00–03:00; 05:00–07:00) and, lastly, another 8-hour sleep opportunity (23:00–07:00). Intra-class correlation coefficients were calculated to examine differences in stability and robustness across different sleep parameters. Results Sleep architecture parameters were less stable and robust than absolute and relative spectral activity parameters. Further, relative spectral activity parameters were less robust than absolute spectral activity. Absolute alpha and sigma activity demonstrated the highest levels of stability that were also robust across sleep opportunities of varying duration and timing. Conclusions Stability and robustness varied across different sleep parameters, but absolute NREM alpha and sigma activity demonstrated robust trait-like behavior across variable sleep opportunities. Reduced stability of other sleep architecture and spectral parameters during shorter sleep episodes as well as across different sleep opportunities has important implications for study design and interpretation.

Children with epilepsy are at risk for impaired social cognition and autism. We aimed at evaluating the utility of the social responsiveness scale (SRS) for assessment of social impairment in these children. Prospective study; the SRS was applied to a group of children with epilepsy and a healthy control group. Intellectual disability in the epilepsy group was assessed utilizing adapted versions of the Wechsler Intelligence and adaptive behavior scales. One hundred and one children with epilepsy and 92 healthy children were included. The majority of children in both groups had normal SRS scores. Significant differences were identified in children with high total scores indicating significant deficiencies in reciprocal social behavior; high scores were found in 16% of children with epilepsy versus 7% of normal children, p < .05, particularly involving social communication, p < .05. Intellectual disability was identified in 42% of children with epilepsy, particularly processing speed index, p < .001. Intellectual disability had a significant effect on total scores, p = .016. Children with epilepsy have increased risk of social impairments. Social impairments are more likely in the presence of intellectual disability. The SRS is a quick identification tool that can be employed in the outpatient setting.
