Prevalence of simple obesity and its high-risk factors in preschool children in Fuzhou, China / 中国当代儿科杂志

OBJECTIVE@#To investigate the prevalence of simple obesity and its risk factors in preschool children in Fuzhou, China.@*METHODS@#The physical examination data of 14 kindergartens in Fuzhou, China were collected by stratified cluster random sampling. The detection rate of simple obesity was calculated. The children with normal body weight were selected as the control group by 1:1 case-control method. The risk factors for childhood simple obesity were investigated by self-made questionnaire and multivariate logistic regression analysis.@*RESULTS@#A total of 5 767 children aged 3-6 years were enrolled in this study. A total of 289 (5.01%) children with simple obesity were screened out, including 153 with mild obesity and 136 with moderate to severe obesity. The prevalence rate of simple obesity gradually increased with the age of children. The multivariate logistic regression analysis showed that the following factors were independent risk factors for simple obesity: preference for fried food (OR=4.789, P<0.05), caregivers' over-concern about diet (OR=4.620, P<0.05), eating before sleep (OR=4.006, P<0.05), eating fast (OR=3.221, P<0.05), preference for sweets (OR=2.282, P<0.05), high birth weight (OR=2.202, P<0.05), overweight or obesity in father (OR=2.074, P<0.05), overweight or obesity in mother (OR=2.047, P<0.05), more than 1.2 times the food intake at the same age (OR=2.013, P<0.05), watching TV (OR=1.665, P<0.05), and lack of exercise (OR=1.463, P<0.05).@*CONCLUSIONS@#The prevalence rate of simple obesity is 5.01% in preschool children in Fuzhou, China. The development of simple obesity is multifactorial. It is suggested that doctors, parents, and teachers should strengthen health education for preschool children, help them develop good living and eating habits, and encourage them to take more exercise, in order to reduce the development of simple obesity.

The relaxation of zonule in primary angle closure suspects / 眼科新进展

Objecttve To compare the difference of relaxation distribution of zonule in different orientations between primary angle closure suspects (PACS) and normal controls,and to explore the role of latent subluxated lens in the pathogenesis of glaucoma.Methods Together 19 eyes of 19 PACS (PACS group) and 19 eyes of 19 age-,gender-and eye-matched normal controls (control group) were enrolled in this study.Pentacam was performed under standardized dark conditions before and 30 min after instillation of compound tropicamide eye drop.Peripheral anterior chamber depth (peri-ACD) of 8 orientations (superior,temporal superior,temporal,temporal inferior,inferior,nasal inferior,nasal,nasal superior position) in the central 4 mm diameter was measured automatically in each eye.The differences of peri-ACD (△ peri-ACD) before and after mydriasis were measured to reflex the relaxation of zonule.The difference of peri-ACD in 8 orientations after mydriasis could confirm the possibility of latent subluxated lens,and its range could verify the degree of lens deviation.Results Significant difference was observed in each groups in terms of △peri-ACD (P＜0.001,0.043).The △peri-ACD of the temporal inferior position was (0.40 ± 0.28)mm in PACS group,which was smaller than that in the control group [(0.55 ±0.15)mm] (P =0.041),but no significant difference was observed between PACS patients and normal controls in other orientations (all P ＞ 0.05).And significant difference was detected between the 8 positions of peri-ACD after mydriasis in each groups (P =0.001,0.009),and these parameters between the two groups were also significantly different (all P ＜ 0.01).Moreover,there was no significant difference in the difference of between the minimum and maximum peri-ACD in the PACS group and the control group [(0.35 ± 0.18)mm vs.(0.43 ± 0.28) mm] (P =0.362).Conclusion The uneven relaxation distribution of zonule may exist in both PACS patients and normal controls,and the relaxation of zonule may be significant in temporal inferior position in PACS patients.

Efficacy of clonidine transdermal patch in treatment of moderate to severe tic disorders in children / 中国当代儿科杂志

<p><b>OBJECTIVE</b>To investigate the difference in the efficacy between clonidine transdermal patch and haloperidol tablets in the treatment of moderate to severe tic disorders in children.</p><p><b>METHODS</b>A total of 134 children with moderate to severe tic disorders were randomly divided into clonidine group (n=70) and haloperidol group (n=64). The clonidine and haloperidol groups were treated with clonidine transdermal patch and haloperidol tablets respectively, and the treatment lasted for 8 weeks in both groups. The Yale Global Tic Severity Scale (YGTSS) was used to evaluate the conditions of the children before and after treatment, and the adverse events during the treatment were recorded.</p><p><b>RESULTS</b>The haloperidol group had a significantly better treatment outcome than the clonidine group after one week of treatment (P<0.05); the treatment outcome showed no significant difference between the two groups after 3, 5, and 8 weeks of treatment (P>0.05). The clonidine group had significantly less reductions in the motor tics, vocal tics, and function impairment scores and total score of YGTSS than the haloperidol group after one week of treatment (P<0.05); there were no significant differences in YGTSS score reductions between the two groups after 3, 5, and 8 weeks of treatment (P>0.05). The clonidine group had a significantly lower overall incidence of adverse events than the haloperidol group (8% vs 37%; P<0.01).</p><p><b>CONCLUSIONS</b>Clonidine transdermal patch and haloperidol are both effective in the treatment of moderate to severe tic disorders in children. The clonidine transdermal patch, despite slow action, has comparable efficacy and fewer adverse effects compared with haloperidol.</p>

Diagnostic performance of macular ganglion cell - inner plexiform layer thickness measured by Cirrus HD-OCT in POAG patients / 国际眼科杂志(Guoji Yanke Zazhi)

AIM: To evaluate the diagnostic accuracy of macular ganglion cell - inner plexiform layer ( GCIPL ) measurements using high- definition optical coherence tomography ( Cirrus HD - OCT ) ganglion cell analysis algorithm for detecting early and moderate to severe glaucoma. METHODS:Twenty normal control persons, 26 patients with early glaucoma and 29 patients with moderate to severe glaucoma were enrolled in this study. Macular GCIPL, optic nerve head ( ONH ) parameters and peripapillary retinal nerve fiber layer ( RNFL ) thickness were measured in each subject. Then all measured results of each parameter were calculated using SPSS17. 0. Areas under the receiver operating characteristic curves ( AUC) of each parameter were calculated to compare the diagnostic accuracy for detecting early and moderate to severe glaucoma. RESULTS: For detecting early glaucoma, AUC of average RNFL and seven clock value of RNFL were the biggest ( 0. 871 and 0. 896 respectively ), the AUC of parameters in GCIPL were also significant, among them, the average GCIPL showed bigger AUC(0. 847) than the minimum GCIPL (0. 812). For diagnosing moderate to severe glaucoma, the AUC of rim area was 0. 992, which was bigger than that of average RNFL ( 0. 991 ). The minimum GCIPL showed bigger AUC ( 0. 983 ) than the average GCIPL (0. 967). For early glaucoma diagnosis, the sensitivity of average RNFL was the highest (76. 9%), while the average GCIPL has the highest specificity (93. 5%). CONCLUSION: AS a new diagnostic parameter for detecting glaucoma, GCIPL shows similar diagnostic potential compared with RNFL. For early glaucoma diagnosis, average RNFL is the most important parameter, while screening early glaucoma, average GCIPL should be paid more attention.

Comparison of anterior segment parameters between fellow eyes of unilateral acute angle closure glaucoma and primary angle closure suspects / 国际眼科杂志(Guoji Yanke Zazhi)

AIM: To explore the differences of anterior segment parameters in the patients with fellow eyes of unilateral acute angle-closure glaucoma ( AACG ) , primary angle-closure suspects ( PACS) and normal group. METHODS: Twenty-six eyes of 26 patients with fellow eyes of AACG, 28 eyes of 28 age- and gender-matched PACS and 34 normal eyes were imaged using optical coherence tomography ( OCT) and pentacam scheimpflug system ( Pentacam ) . Anatomical parameters including central corneal thickness ( CCT ) , corneal volume ( CV ) , pupillary diameter ( PD ) , central anterior chamber depth ( CACD ) , peripheral anterior chamber depth ( PACD ) , anterior chamber volume ( ACV ) and anterior chamber angle ( ACA) were obtained from Pentacam. Iris thickness (IT750,IT2000), cross-sectional area (IS), volume (IV) and angle opening distance 500 (AOD500) were estimated using OCT combined with a computer image processing. Statistic analysis was performed with SPSS. RESULTS: There were no significant differences in corneal parameters (CCT, CV), PD and iris values (IT750, IT2000, IS, IV) among the three groups (P> 0. 05). Compared with the fellow eyes of AACG and PACS, normal eyes had larger ACV, wider AOD500 and ACA, deeper CACD and PACD ( P 0. 05). Using the fellow eyes of AACG as the standard to predict high risk of angle closure, areas under the receiver operating characteristic curve of the above parameters were all less than 0. 7. CONCLUSION:All the anterior segment parameters are no different significantly between the fellow eyes of AACG and PACS. They may be notaccurate criteria for determining high risk group of PACS.
