Objective To discuss the treatment method and effectiveness of Seymour fracture in children and adolescents. Methods Between January 2013 and November 2015, 26 children and adolescents with Seymour fractures were treated. There were 18 males and 8 females, aged from 1 year and 1 month to 17 years (median, 8.2 years). The injury causes included crush in 14 cases, bruise in 10 cases, and puncture in 2 cases. The thumb was involved in 2 cases, index finger in 1 case, middle finger in 12 cases, ring finger in 6 cases, and little finger in 5 cases. The time from injury to operation was 1-15 hours (mean, 3.2 hours). The patients underwent debridement, nail removal, nail matrix repair, closed reduction and osteosynthesis with Kirschner wires, and splinting in emergency. Kirschner wires and splints were removed at 4 weeks after surgery, and functional exercises were done. Results All wounds healed by first intention without infection. The follow-up duration was 2-24 months (mean, 12.3 months). The fracture healing was obtained at 1-2 months (mean, 1.4 months) on X-ray film, and no complications of nonunion, malunion, re-displacement, premature epiphyseal closure, or no growth of the nails occurred. Nail deformity developed in 1 case and no re-operation was given. At last follow-up, 1 patient had 10° extension limitation of the distal interphalangeal joint, but the flexion was normal. The motion range of distal interphalangeal joint was 0-75°, showing no significant difference when compared with that of contralateral side (0-78°). Conclusion The effectiveness for treating Seymour fracture is satisfactory by debridement, nail removal, nail matrix repair, closed reduction and osteosynthesis with Kirschner wires, and splinting in emergency.
Objective To analyze the correlation between the polymorphism on interleukin 6 (IL-6) gene promoter region-174 locus and adolescent idiopathic scoliosis (AIS), including the susceptibility, the bracing effectiveness, and the possible mechanism. Methods The 182 AIS patients and 210 healthy controls who met the inclusion criteria between January 2013 and January 2016 were collected as research objects. The genotype of IL-6 gene promoter region-174 locus, the serum IL-6, the bone mineral density (BMD) of femoral neck and vertebrae (L1–4), and the bone metabolism parameters, including bone alkaline phosphatase (BALP), bone gla protein (BGP), tartrate resistant acid phosphatase 5b (TRACP-5b), urine Ca, and urine Ca/Cr, were detected. All research objects were divided into the AIS group and the control group according to whether they had AIS, the GG, CG, CC groups according to their genotype, and progression-free group and progression group according to the therapeutic effectiveness of 1-year bracing treatment. Statistical analysis for the indexes were conducted respectively. Results There were significant differences in AIS history, BMD of femoral neck and lumbar vertebrae between the AIS group and control group (P<0.05). According to the therapeutic effecitveness of 1-year bracing treatment, 182 AIS patients were divided into progression-free group in 110 cases and progression group in 72 cases. The results of single factor analysis showed that there were significant differences in the genotype and allele distribution of IL-6 gene promoter region-174 locus, BMD of femoral neck and lumbar vertebrae, IL-6, TRACP-5b, urine Ca, and urine Ca/Cr between the progression-free group and progression group (P<0.05). The results of multivariable analysis showed that the BMD of lumbar vertebrae, TRACP-5b, and urine Ca were the influencing factors of bracing efficacy (P<0.05). According to the results of genotype detection, all research objects were divided into GG group in 264 cases, CG group in 104 cases, and CC group in 24 cases. The IL-6, TRACP-5b, urine Ca, and urine Ca/Cr of GG type carriers were higher and BMD of femoral neck and lumbar vertebrae were lower when compared with the CG and CC type carriers (P<0.05). The BMD of lumbar vertebrae of CG type carriers was lower than that of CC type carriers (P<0.05). Conclusion The polymorphism of IL-6 genepromoter region-174 locus wasn’t correlated with the AIS susceptibility, but it was correlated (not independently correlated) with the scoliosis progression under bracing treatment, and the risk for G-carried patients was higher. The mechanism may be that the polymorphism affected the IL-6 expression level and eventually affected the BMD of AIS patients through the bone metabolism.
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.
ObjectiveTo investigate the effectiveness and technical key points of limb salvage surgery by allotransplantation of cryopreservated vascularized bone in children and adolescents with osteosarcoma. MethodsA retrospective analysis was made on the clinical data of 21 children and adolescents with osteosarcoma receiving limb salvage surgery by allotransplantation of cryopreservated vascularized bone from their relatives between February 2004 and April 2012. There were 13 males and 8 females, aged from 7 to 16 years (mean, 12.6 years). According to Enneking stage system, 15 cases were rated as stage ⅡA and 6 cases as stage ⅡB. The tumors located at the distal femur in 10 cases, at the proximal femur in 1 case, at the proximal tibia in 8 cases, at the proximal humerus in 1 case, and at the distal radius in 1 case. Imaging examination showed that epiphyseal extension of malignant bone tumors in 7 cases. The iliac bone allograft with deep iliac vessels was obtained from their lineal consanguinity. After preservation by a twostep freezing schedule, the iliac bone allograft with deep iliac vessels was implanted into the bone defect area after tumor resection. The size of iliac bone flap was 8.0 cm×3.0 cm×2.0 cm-14.0 cm×5.0 cm×2.5 cm. Reserved joint surgery was performed on 16 cases and joint fusion surgery on 5 cases, and external fixation was used in all cases. The chemotherapy was given according to sequential high-dose methotraxate, adriamycin, and cisplatine before and after operation. ResultsAll 21 cases were followed up from 5 months to 11 years (mean, 6.4 years). At 2 weeks after operation, the erythrocyte rosette forming cells accounted for 56.7%±3.9%, showing no significant difference when compared with that of normal control (58.3%±4.3%) (t=1.56, P=0.13), which suggested no acute rejection. At 4 weeks after operation, single photon emission computerized tomography bone scan indicated that the blood supply of bone graft was rich, and the metabolism was active. At 12 weeks after operation, the digital subtraction angiography showed the artery of iliac bone flap kept patency. X-ray films showed that malunion and non-union occurred at 5 and 6 months after operation in 1 case, respectively. The bone graft healed in the other patients, and the healing time was 3.2-6.0 months (mean, 4.4 months). At last follow-up, American Musculoskeletal Tumor Society (MSTS) score was significantly improved to 26.80±2.14 from preoperative value (17.15±1.86) (t=-4.15, P=0.00). The survival rate was 85.7% (18/21) and the recurrence rate was 9.5% (2/21). ConclusionAllotransplantation of cryopreservated vascularized bone from the relatives provides a new method for the treatment of osteosarcoma in children and adolescents. A combination of allotransplantation and chemotherapy can achieve the ideal treatment effect. The correct cutting, preservation, and transplantation of the donor bone, and indication are the key to improve the effectiveness.
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.
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.
ObjectiveTo compare the efficacy of different family-based interventions on reducing screen-based exposure among children and adolescents using a network meta-analysis method. MethodsThe CNKI, WanFang Data, CBM, VIP, PubMed, Web of Science, Embase, Cochrane Library databases were electronically searched to collect randomized controlled trials (RCTs) related to the objectives from inception to September 11, 2024. Two reviewers independently screened literature, extracted data and assessed the risk of bias of the included studies. Network meta-analysis was then performed by using Stata and R software. ResultsA total of 17 RCTs involving 2 490 participants were included. The results of the network meta-analysis showed that compared with waiting lists, health education, alternative behavior combined with screen exposure-restricted environment and rule-setting, behavior monitoring combined with health education, and physical activity combined with alternative behavior could reduce total screen time. The intervention effect of alternative behavior combined with behavior monitoring in reducing total screen time was superior to other intervention measures. Increasing exercise could reduce TV/DVD viewing time. Compared with health education, behavior monitoring combined with health education could reduce weekend screen time. ConclusionThe current evidence indicates that health education, alternative activities combined with screen exposure-restricted environment and rule-setting, behavior monitoring combined with health education, physical activity combined with alternative activities, physical activity alone, alternative activities combined with behavior monitoring have certain advantages in reducing screen-based exposure among children and adolescents.
ObjectiveTo observe the clinical efficacy of minimally invasive vitreous surgery (MIVS) for special rhegmatogenous retinal detachment (RRD) in children and adolescents.MethodsA retrospective clinical comparative study. Fourteen eyes with special type of RRD in 14 children and adolescents who received the MIVS treatment from January 2014 to January 2019 in Ophthalmology Department of The First Affiliated Hospital Ophthalmology of Air Force Military Medical University, were included in this study. Among them, 8 eyes from 8 males and 6 eyes from 6 females. The age of them ranged from 5 to 17, with the mean age of 12.64±4.11 years. The course of disease was ranged from 1 d to 1 year, and the average of it was 30 d. All the eyes developed the special type RRD, including pseudophakic and aphakic retinal detachment, giant retinal tear with retinal detachment, choroidal detachment associated with retinal detachment, and RRD with ocular dysplasia. In the 14 eyes, there was 2 eyes with retinal detachment in 1 quadrant, 4 eyes in 2 quadrants, 1 eye in 3 quadrants and 7 eyes in total 4 quadrants. All the eyes were treated with 23G or 25G MIVS and filled with irrigation solution, air and silicone oil. In addition, 10.4 months' follow-up for average after surgery were taken to observe the occurrence of retinal reattachment, BCVA and related complications in the eyes.ResultsIn the 14 eyes, 13 (92.9%) of them attained retinal reattachment and 1 eye (7.1%) got a poor retinal reattachment after one operation. At the last follow-up, all the 14 eyes (100.0%) attained retinal reattachment and 5 of them at the filling state of silicone oil. The vision of 8 eyes (57.1%) were improved, 4 eyes (28.6%) have no notable changes and 2 eyes decreased (14.3%). During the operation, iatrogenic retinal breaks were occurred in 1 eye, and silicone oil entered underneath the retina in 1 eye. After the operation, 1 eye suffered a relapse of retinal detachment after the removal of silicone oil and then were filled with it again.ConclusionsMIVS is a safe and effective way to treat the special type RRD among the children and adolescents. The rate of retinal reattachment is 92.9% after one surgery and 100.0% at the last follow-up. Therefore, MIVS can help most of eyes with special type RRD to get a stable and improved vision.
Objective To systematically evaluate and comparatively analyze the mental health status of adolescents with different genders in middle schools of China, and to provide scientific evidence for the improvement of adolescents’ mental health level. Methods Such databases as CNKI, VIP, WanFang Data, and CBM (1989 to Dec, 2009) were searched. Data were extracted from the included literature and RevMan 4.2 software was used for meta-analyses. Results Twenty-seven original literatures were included. The results of meta-analyses showed: the total anxious trend of girls was higher than that of boys (OR= –?2.14, 95%CI –?2.93 to –?1.35, Plt;0.000 01); the result of each scale displayed that girls scored higher than boys in terms of study-anxiety (OR= –?0.53, 95%CI –?0.67 to –?0. 39, Plt;0.00001), social-anxiety (OR= –?0.30, 95%CI –?0.45 to –?0.15, Plt;0.000 1), self-accusation trend (OR= –?0.30, 95%CI –?0.46 to –?0.13, Plt;0.000 6), allergy trend (OR= –?0.18, 95%CI 0.31 to –?0.05, P=0.008), body symptom (OR= –0.21, 95%CI –0.34 to –0.08, P=0.001), and phobia trend (OR= –?0.80, 95%CI –?0.91 to –?0.68, Plt;0.000 01); No significant differences were identified between boys and girls in terms of solitude trend (OR=0.09, 95%CI –?0.04 to 0.22, P=0.2) and actuation trend (OR=0.06, 95%CI –?0.15 to 0.28, P=0.56). Conclusion Targeted measures should be taken for adolescent mental health education, especially for girls.
ObjectiveTo systematically review the association between chronotype and depressive symptoms among adolescents. MethodsCNKI, VIP, WanFang Data, PubMed, ScienceDirect and Web of Science databases were electronically searched to collect studies on the association between adolescent chronotype and depressive symptoms from inception to January 17th, 2022. Two reviewers independently screened literature, extracted data, and assessed the risk of bias of the included studies. Meta-analysis was then performed using Stata 16.0 software. ResultsA total of 12 studies were included. The results of meta-analysis showed that there was an association between chronotype and depressive symptoms (Fisher’s Z=?0.19, 95%CI ?0.21 to ?0.17, P<0.001). ConclusionCurrent evidence shows that evening-type chronotype may be a risk factor for depressive symptoms among adolescents. Due to the limited quality and quantity of the included studies, more high-quality studies are needed to verify the above conclusion.
