ObjectiveTo observe the clinical features of retinal arterial occlusion (RAO) in youth.MethodsThis is a retrospective case review. Nine patients (9 eyes) with RAO were enrolled in this study. There were 6 males (6 eyes) and 3 females (3 eyes). The average age was (14.22±3.93) years. The best-corrected visual acuity (BCVA), indirect ophthalmoscopy, fundus color photography and fundus fluorescein angiography were performed. All patients underwent systemic evaluation including blood routine, erythrocyte sedimentation rate, blood lipids, vasculitis screening, homocysteine level, antiphospholipid antibody, blood coagulation, neck vascular ultrasound, and cardiac color ultrasound and electrocardiogram examination. All patients received oxygen therapy, blood medications and symptomatic treatment. Meanwhile, the patients with autoimmune diseases were received systemic glucocorticoid therapy. The follow-up was ranged from 6 to 12 months. The visual acuity and fundus change before and after treatment were compared.Resultsamong 9 patients, one patient had systemic lupus erythematosus, one patient had congenital heart disease, one patient had hypergammaglobulinemia, and carotid artery color ultrasonography showed that the internal carotid artery vessels faltered in 2 cases. The BCVA was 0.01 - 0.12. Among 9 eyes, there were 5 eyes (55.6%) with retinal branch artery occlusion (BRAO), 2 eyes (22.2%) with central retinal artery occlusion (CRAO), 2 eyes (22.2%) with ciliary retinal artery occlusion (CLAO). CRAO eyes showed positive RAPD (relative afferent pupillary defect), fine retinal artery and the corresponding vein, pale white retinal edema in posterior area and macular cherry-red spot. BRAO eyes manifested as inferior temporal artery occlusion and pale white retinal edema around them. CLAO eyes showed temporal ligulate grey-white retinal edema. At the last follow-up, BCVA improved and retinal vessels returned to normal in 7 eyes (77.8%); BCVA unchanged and no improvement in fundus in 2 eyes (22.2%).ConclusionAdolescent RAO is mostly partial occlusion, the prognosis is generally good after early active treatment.
Objective To review the advances in double-bundle anterior cruciate ligament (ACL) reconstruction in adolescents at home and abroad. Methods Recent literature about double-bundle ACL reconstruction in adolescents at home and abroad was extensively consulted, and the relationship between bone canal and epiphyseal plate, clinical verification of surgical safety, and clinical effectiveness of double-bundle ACL reconstruction in adolescents were summarized and analyzed. Results Double-bundle ACL reconstruction has certain advantages in clinical stability and re-rupture rate when compared with single-bundle ACL reconstruction in adolescents, and there is no significant difference in safety between them. Conclusion Double-bundle ACL reconstruction in adolescents can achieve lower re-rupture rate and better stability when compared with single-bundle reconstruction. However, the sample size of clinical research is too small, and the follow-up time is too short, so the effectiveness needs to be continuously observed.
Early onset and high incidence of myopia has caused great concern of the Party and the Government. On August 30th 2018, eight ministries and commissions, such as the Ministry of Education, jointly issued the Comprehensive Prevention and Control Implementation Scheme of Child and Adolescent Myopia, which put forward the actions and specific measures to various aspects, and particularly mentioned that the medical and health institutions should work together with families, schools, etc, to reduce the incidence of myopia. Medical institutions should do a good job in the following items: setting up visual archives for adolescents, so as to prevent and control myopia with pertinence and individualization; standardizing the process of diagnosis and treatment, doing a good job in refractive examination and correction of adolescents, and resolutely combating the commercial "treatment and correction" of myopia; strengthening myopia-related health education, and eliminating erroneous understanding to myopia prevention and control. Optometrists should play an important role in the prevention and control of myopia, speed up the cultivation of optometry talents, and call on the state to establish a professional title system and professional access standards for optometry talents as soon as possible.
Objective To explore the association between behavioral, emotional problems and life events among adolescents, and to determine which factors of life events correlate most highly with the behavioral, emotional problems. Method A total of 1 325 adolescents were investigated with Youth Self-Report (YSR) of Achenbach’s behavior checklist and Adolescent Self-Rating Life Events Checklist (ASLEC), and the data were analyzed with canonical correlation analysis. Results Canonical correlation was statistically significant. The correlation coefficients of the first pair of canonical variables in the male and female group were 0.631 3 and 0.621 1, respectively, and the cumulative proportion of the first two pairs of canonical variables was above 0.95. In the first pair of canonical variables, the loadings of anxious/depressed, interpersonal sensitivity and study pressure were higher, while in the second pair, withdrawal and punishment were the most important factors. Conclusions The effects of life events on emotional problems mainly contributed to interpersonal sensitivity and study pressure.
Objective To systematically review the rate of sleep deprivation in children and adolescents in China from 2004 to 2019. Methods PubMed, The Cochrane Library, EMbase, Web of Science, CBM, CNKI and WanFang Data databases were searched to collect cross-sectional studies on the sleep deprivation rate of children and adolescents in China from inception to July 15th, 2021. Two researchers independently screened literature, extracted data and evaluated the risk of bias of the included studies. Meta-analysis was then performed by using Stata 15.0 software. Results A total of 45 cross-sectional studies were included, with a total sample size of 769 918 participants, of whom 587 457 reported sleep deprivation. The results of meta-analysis showed that the sleep deprivation rate of Chinese children and adolescents was 61% (95%CI 55% to 68%). Subgroup analysis indicated that the sleep deprivation rates were 62% for female children and 59% for male children. The rate was 84% in junior high school, 80% in high school and 64% in primary school. The rates in south China, southwest China, northwest China, north China, east China and central China were 68%, 62%, 61%, 57%, 57% and 54%, respectively. The rate of sleep deficiency based on "health requirements for daily study time of primary and junior school students" was the highest at 74% (95% CI 70% to 79%). The cumulative meta-analysis by time showed that the sleep deprivation rate had gradually stabilized and approached 60% since 2011. Conclusion Current evidence shows that the sleep deprivation rate of Chinese children and adolescents is high. Due to the limited quality and quantity of included studies, more high-quality studies are needed to verify the above conclusion.
ObjectiveTo identify the prevalence of distal adding-on phenomenon after posterior selective fusion in type Lenke 1A idiopathic scoliosis, to analyze its risk factors so as to find the reasonable choice for lowest instrumented vertebra (LIV). MethodsA retrospective study was made on the clinical data of 43 patients with type Lenke 1A idiopathic scoliosis undergoing posterior selection fusion with pedicle screw instrumentation between July 2011 and December 2015. There were 15 males and 28 females, aged 12-18 years (mean, 16 years). The preoperative Cobb angle was (50.1±11.3)°. The anteroposterior and lateral radiographs were taken at preoperation, immediate after operation, and last follow-up to measure the radiographic parameters. Forty-three patients were divided into adding-on group and control group according to whether or not the occurrence of distal adding-on phenomenon on anteroposterior radiographs of the spine at last follow-up. All the factors that maybe cause distsal adding-on were evaluated by statistical analysis. ResultsThe patients were followed up 12-50 months (mean, 26.5 months). At last follow-up, distal adding-on was observed in 10 of 43 patients (23.3%), including 2 males (13.3%) and 8 females (28.6%). Univariate analyses showed following several factors associated with adding-on:preoperative lumbar flexibility, preoperative pelvic tilt in coronal plane, preoperative LIV+1 deviation from center sacral vertical line, L4 subtype, the difference between LIV and last touching vertebra (LTV) (LIV-LTV), the difference between LIV and lower end vertebra (LEV) (LIV-LEV), and the difference between LIV and stable vertebra (SV) (LIV-SV). The risk factors above were brought into Logistic regression model, the results showed that preoperative LIV+1 deviation (deviation>10 mm, odds ratio=10.812, P=0.026), LIV-LTV (LIV-LTV<1, odds ratio=9.017, P=0.04), and L4 subtype (1A-R, odds ratio=9.744, P=0.047) were significantly associated with adding-on. ConclusionPreoperative LIV+1 deviation of >10 mm, L4 subtype (1A-R) and LIV-LTV of <1 are independent predictive factors of adding-on after surgery. As high risk of adding-on was closely related with the incorrect fusion level, it plays an important role for surgeons to decide the level of the fusion before surgery thoroughly. The LIV should be extended at least to LTV+1 to avoid adding-on phenomenon.
ObjectivesTo systematically review the association between bullying and risk of non-suicidal self-injury among adolescents.MethodsPubMed, MEDLINE, EMbase, The Cochrane Library, CNKI and WanFang Data were searched from inception to September 1st 2017 to collect studies on the association between bullying and non-suicidal self-injuries. Two reviewers independently screened literature, extracted data and assessed the risk of bias of included studies by Agency for Healthcare Research and Quality (AHRQ). Then, meta-analysis was performed using CMA 2.2 software.ResultsA total of 23 studies involving 18 819 participates were finally included. The results of meta-analysis showed that bullying victims reported more NSSI than uninvolved adolescents (OR=2.41, 95%CI 1.96 to 2.96, P<0.001). The bullying perpetrators reported more NSSI than uninvolved adolescents (OR=2.26, 95%CI 1.39 to 3.68,P=0.001). Individuals acting as both victims and perpetrators could also increase risks of NSSI (OR=2.76, 95%CI 1.17 to 6.51, P=0.02). Using meta-regression, it was found that the relation between NSSI and bullying victimization was significantly moderated by age, with studies in which respondents were younger reporting larger effect sizes than studies in which respondents were older (B=–0.33, 95%CI –0.38 –0.28, P<0.001).ConclusionsThe current study demonstrates that involvement in bullying in any capacity is associated with non-suicidal self-injuries. Due to the limitation of research, more studies are required to verify above conclusions.
Objective To systematically review literature on the influencing factors related to adolescent sub-health problems. Methods We electronically searched the following four databases including CBM, VIP, CNKI and WanFang Data to collect Chinese literature on adolescent sub-health status and problems in China published before May 2012. Two reviewers independently screened literature, extracted data, and cross checked records. Then qualitative analysis was applied. Results According to the inclusion and exclusion criteria, 41 cross-sectional studies were included. The results of qualitative analysis showed that the influencing factors of adolescent sub-health could be classified into four categories including social factors, family factors, school factors, and interpersonal relationships. The main ones were social support, employment pressure, family economic conditions, learning burden, unhealthy habits, etc. Conclusions There are many influencing factors of adolescent sub-health with interaction. Due to the limitation of the included studies, more prospective cohort studies are needed to provide high quality evidence.
Adolescent idiopathic scoliosis refers to a three-dimensional spinal deformity or structural change that occurs in adolescence. The rotation of the vertebral body is greater than or equal to 10°. In order to avoid affecting the physical and mental health of patients, appropriate intervention and treatment of adolescent idiopathic scoliosis should be carried out as soon as possible. Based on the summary of non-surgical treatment of adolescent idiopathic scoliosis at home and abroad, this paper systematically introduces the mainstream early non-surgical treatment of adolescent idiopathic scoliosis, including observation and follow-up, electrical stimulation therapy, Chinese traditional chiropractic techniques, massage and manual reduction, functional training and exercise therapy, traction therapy and brace therapy, in order to provide a reference for the possible treatment research direction of adolescent idiopathic scoliosis in the future.
ObjectiveTo review the recent progress in research on the role of estrogen and estrogen receptor on the onset and progression of adolescent idiopathic scoliosis (AIS). MethodsThe recently published clinical and experimental 1iterature at home and abroad on abnormality of estrogen and its receptor in AIS was reviewed and summarized. ResultsThere are many abnormal changes of estrogen and estrogen receptor in most AIS patients, including higher serum estrogen concentration, unusual cellular response to estrogen, late age at menarche, and gene polymorphisms of estrogen receptor, which are closely associated with AIS predisposition, curve severity, and scoliosis progression. ConclusionEstrogen and its receptor participate in the onset and progression of AIS by certain mechanisms, but exact mechanism remains indefinite, which needs further research to better define the role of estrogen and its receptor in AIS.
