Effect of Social Media Celebrities on Children’s Satisfaction with Their Body Image

This study investigated the impact of social media and media on children’s body satisfaction in early childhood.The effect of social media and media on children’s body image and differences between girls’and boys’acceptance of their body image were explored.A questionnaire and an illustrated body satisfaction scale were distributed to a sample of 491 children in Saudi Arabia(246 girls,245 boys)aged 5-7 years.The results revealed differences between children’s responses to the illustrated body satisfaction scale and questionnaire.Questionnaire data revealed children were satisfied with their body image(91.4%,standard deviation[SD]0.53),skin color(91.2%,SD 0.53),and weight(79.6%)and did not want to change their shape(73.7%).However,the illustrated body satisfaction scale indicated many children wanted to be like social media celebrities(37.9%),television and film celebrities(32.6%),and famous singers(25.5%).No statistically significant differences were found between girls and boys in body satisfaction,although 66.9%of boys wanted the shape of their body to be more muscular,and girls wanted blue or green eyes and blond hair.This study also revealed Disney princesses had a major effect on girls compared with other media.The researcher recommends conducting longitudinal studies in Arab societies,particularly in Saudi Arabia,to explore the influence of celebrities on children as they age.Importantly,educational policymakers should include pictures of Arab children in the curricula instead of foreign children.

Pediatric CT of the Lung: Influences on Image Quality

Objective: To assess influential factors of CT on image quality of the lung in children. Materials and methods: Retrospective evaluation of 82 consecutive chest-CT-scans in 50 children (1-16 years, 17 females and 33 males). Two pediatric radiologists evaluated in consensus the subjective image quality on lung windows using a 4-point scale (1 = very good, 2 = good, 3 = moderate, 4 = poor). Ventilation, motion artifacts and beam hardening artifact were included in this score. The effects of the following factors were evaluated: 1) CT-settings (tube energy, tube current);2) Patient’s age, weight, chest size, ventilation;3) Artifacts of devices, tubes and lines;4) Combination MRI of the abdomen prior to CT of the chest with the same sedation/anesthesia in oncological patients. Results: The odds of having a better image quality increase with patient’s age, weight and chest diameter in a multiple-factor model. There was no difference between tube current protocols. In infants (15 kg) subjective image quality was good in only 1 (8%), moderate in 8 (67%) and poor in 3 (25%) scans. In childhood and adolescence (15 - 90 kg) 25 (36%) scans were very good, 28 (40%) good, 15 (21%) moderate and 2 (3%) poor. Artifacts of tubes and lines have no statistical significant influence on image quality. Lower lung densities were related to better ventilation and older children. Conclusion: Increasing dose parameters may not increase necessarily subjective image quality in infants (15 kg), rather than good ventilation, optimal preparation and avoiding artifacts. A possible explanation of the rather moderate image quality in infants may be the alveolar stage of the lung. Up to two years of age the lung has a high specific lung volume per kg and a low total lung volume with a low alveolar surface.

Contribution of Medical Imaging in the Diagnosis of Urinary Disorders in Children at the Charles de Gaulle University Hospital in Ouagadougou

Purpose: The purpose of our study, which focused on the contribution of medical imaging in the diagnosis of urinary tract diseases in children at the Charles de Gaulle University Hospital of Ouagadougou, was to study the role of medical imaging in the diagnosis of urinary tract diseases in patients aged 15 years or less at the CHUP-CDG. Patients and Methods: This was a descriptive cross-sectional study with the retrospective collection covering the period from January 1, 2009 to December 31, 2018, i.e., 10 years. We collected a total of 833 medical imaging examinations, performed in 735 patients. The mean age of the patients was 40 months, infants accounted for 37.69% of the cases. Male patients were more numerous with a sex ratio of 1.53. Results: Ultrasonography was performed in 652 patients or 78.27%, ASP RX in 128 patients or 10.88%. URC and UIV were used in 6.53% and 0.68% of patients, respectively. CT and MRI were not performed in our study. The most frequent clinical urinary signs were dysuria (58.13%) and hematuria (43.94%). Ultrasonography was the most requested examination (78.27%), followed by conventional radiography (15.37%). Urinary lithiasis was by far the most common urinary condition (46.86%), followed by urinary tract infections (32.19%) and malformative uropathies (14.93%), of which the posterior urethral valve was the most frequent. Imaging was also used to find other conditions associated with urinary tract diseases. Conclusion: Medical imaging plays a major role in the diagnosis and management of urinary tract diseases in children. It has limitations, that is why a formal meeting between clinicians and radiologists is necessary for a better choice of imaging techniques and efficient management of these conditions.

Ultrasound diagnosis of congenital Morgagni hernias: Ten years of experience at two Chinese centers

BACKGROUND Morgagni hernias are rare anomalies that are easily misdiagnosed or missed.AIM To summarize the ultrasound(US)imaging characteristics of Morgagni hernias through a comparison of imaging and surgical results.METHODS The records of children with Morgagni hernias who were hospitalized at two hospitals between January 2013 and November 2023 were retrospectively re-viewed in terms of clinical findings,US features,and operative details.RESULTS Between 2013 and 2023,we observed nine(five male and four female)children with Morgagni hernias.Upper abdominal scanning revealed a widening of the prehepatic space,with an abnormal channel extending from the xiphoid process to the right or left side of the thoracic cavity.The channel had intestinal duct and intestinal gas echoes.Hernia contents were found in the transverse colon(n=6),the colon and small intestine(n=2),and the colon and stomach(n=1).Among the patients,seven had a right-sided lesion,two had a left-sided lesion,and all of them had hernial sacs.CONCLUSION US imaging can accurately determine the location,extent,and content of Morgagni hernias.For suspected Mor-gagni hernias,we recommend performing sonographic screening first.

Accuracy of multi-echo Dixon sequence in quantification of hepatic steatosis in Chinese children and adolescents

BACKGROUND Nonalcoholic fatty liver disease(NAFLD) is currently the outstanding cause of chronic liver disease in children and adolescents, especially in overweight and obese groups. Liver biopsy is the reference standard to diagnose NAFLD but invasive, thus it is not the best choice in clinical diagnosis and follow-up.Magnetic resonance(MR) is widely used in clinical trials to noninvasively quantify liver fat content in adults and children in foreign countries. While currently, it is rarely used in Chinese children and adolescents. We postulated that quantifying hepatic steatosis by MR could be extended to children and adolescents in China.AIM To investigate the accuracy of MR imaging(MRI) in quantifying liver fat with MR spectroscopy(MRS) as a reference. A secondary goal was to assess the prevalence of NAFLD in overweight and obese Chinese children and adolescents.METHODSThere were 86 children and adolescents enrolled in this study, including 65 overweight and obese children and 21 healthy children. The participants underwent MRI and MRS. MRI and MRS were performed using multi-echo Dixon and HISTO sequences, respectively, to calculate hepatic proton density fat fraction(PDFF). Hepatic steatosis was diagnosed using MRS-PDFF > 5% as the threshold. Spearman's analysis was used to evaluate the correlation between MRI and MRS. The agreement between these two methods was assessed by BlandAltman analysis.RESULTS The MRI-PDFF in the MRS region of interest and the entire liver was 9.9% ±10.3% with a range of 0.3%-39.9%, and 10.6% ± 9.4% with a range of 1.9%-38.9%,respectively. The MRS-PDFF was 9.1% ± 10.0%, with a range of 0.5%-37.8%. The incidence of hepatic steatosis detected by MRS-PDFF was 46.5%(40/86) of all participants, all of whom belonged to the overweight and obese group.Spearman's analysis indicated an excellent correlation between multi-echo Dixon and MRS(r > 0.9, P < 0.01). Bland-Altman analysis also demonstrated a good agreement between these two methods.CONCLUSION Multi-echo Dixon shows an excellent correlation and agreement with MRS in quantifying liver fat content and could be a potential tool to detect hepatic steatosis in Chinese children and adolescents.

MRI在诊断Legg-Clavé-Perthes病中的应用进展

Legg-Clavé-Perthes病(LCPD)即儿童股骨头骨骺缺血性坏死,是儿童髋关节结构紊乱中常见且重要的疾病之一,在临床诊治前必须对其疾病过程进行严格的评估,X线平片已广泛应用于LCPD分期。然而,随着MR成像技术的发展,MRI也可以早期发现股骨头骨骺信号的变化,监测LCPD病人股骨近端形态变化;MRI还能够评估坏死早期的血运、预测预后等,为其术前的临床评估提供了更多依据。就近年来MRI在LCPD中的研究进展予以综述。

Magnetic resonance imaging diagnosis of acute Guillain-Barré syndrome in children

The present study examined 24 children with acute Guillain-Barre syndrome using magnetic resonance imaging （MRI） plain scans and fat-suppressed enhanced Tl-weighted imaging （T1WI） scans. Axial MRI plain scans centering on the medullary conus were positive in nine patients （38%）. These displayed variable thickening involving the cauda equina with isointensity on T1WI and isointensity or slight hyperintensity on T2WI. False negatives were obtained in patients with cervical and cranial nerve symptoms. Contrast enhancement of T1WI with fat suppression was positive in all patients in the cauda equina with varied thickening and enhancement centering on the medullary conus. Five patients （36%） were positive in the cervical nerves and 3 patients （50%） were positive in the cranial nerves. These patients had corresponding cervical and cranial nerve symptoms, respectively. Patients with serious clinical symptoms in the lower limbs exhibited obvious involvement of the cauda equina by MRI. Statistical analysis revealed a positive correlation between the extent of enlargement of the cauda equina, centering on the medullary conus, and cerebrospinal fluid protein concentration.

Quito Municipal Schools—Cohort Study: Self-Perception of Body Image and Factors Related with It

Self-perception of body image is one factor to be considered when planning and performing preventive initiatives and interventions in childhood and adolescence. The aim of this study was to analyse self-perception of body image in relation to body-mass index, physical inactivity, not eating breakfast, dieting, smoking and alcohol consumption or toxic habits. Materials and Methods: using data from the “Quito municipal schools” cohort study 6964 students aged from 9 to 17 years were described using a multivariate log linear model of the multidimensional table generated by the variables. A logistic regression model was then fitted to assess associations via OR. Results: 8.2% perceived themselves as overweight. Of those subjects overweight according to their BMI, 21.8% perceived themselves as such, while among those not overweight according to BMI, 96.8% considered themselves as slim or of normal weight. Among students who were dieting, 15.1% perceived themselves as overweight. Among those pupils who perceived themselves has having excess weight, the most common reasons for dieting were: lose weight (56.8%), be healthier (22.6%), and maintain current weight (8.4%). Self-perception of excess weight interacts with excess weight (ORadjusted 8.42;CI95% 6.92-10.25), no breakfast (ORadjusted 2.83;CI95% 2.13-3.77), diet (ORadjusted 2.38;CI95% 1.95-2.89), and with all the variables except toxic habits (ORadjusted 1.01;CI95% 0.78 a 1.29). Conclusion: Interventions to prevent obesity in childhood and adolescence ought to take account of specific determinants within the personal, behavioural and socio-environmental factors, such as the promotion of a positive body image.

Application of voxel-based morphometric method to detect brain changes in children with non-cyanotic congenital heart disease

BACKGROUND Congenital heart disease(CHD)is a cardiovascular malformation caused by abnormal heart and/or vascular development in the fetus.In children with CHD,abnormalities in the development and function of the nervous system are common.At present,there is a lack of research on the preoperative neurological development and injury in young children with non-cyanotic CHD.AIM To determine the changes in white matter,gray matter,and cerebrospinal fluid(CSF)by magnetic resonance imaging(MRI)in children with non-cyanotic CHD as compared with healthy controls.METHODS Children diagnosed with non-cyanotic CHD on ultrasonography(n=54)and healthy control subjects(n=35)were included in the study.All the subjects were aged 1-3 years.Brain MRI was performed prior to surgery for CHD.The SPM v12 software was used to calculate the volumes of the gray matter,white matter,CSF,and the whole brain(sum of the gray matter,white matter,and CSF volumes).Volume differences between the two groups were analyzed.Voxel-based morphometry was used to compare specific brain regions with statistically significant atrophy.RESULTS Compared with the control group,the study group had significantly reduced whole-brain white matter volume(P<0.05),but similar whole-brain gray matter,CSF,and whole-brain volumes(P>0.05).As compared with the healthy controls,children with non-cyanotic CHD had mild underdevelopment in the white matter of the anterior central gyrus,the posterior central gyrus,and the pulvinar.CONCLUSION Children with non-cyanotic CHD show decreased white matter volume before surgery,and this volume reduction is mainly concentrated in the somatosensory and somatic motor nerve regions.
