学习困难儿童智力及记忆力特征分析

目的探讨学习困难儿童的智力、记忆力特征。方法学习困难(LD)根据ICD-10五条诊断标准,精神发育迟滞(MR)根据国际疾病分类第10版(ICD-10)诊断标准,分为实验组LD组;对照组a.正常组,b.弱智组。采用中国韦氏儿童智力量表进行智力测验,记忆力测验采用中国科学研究院编制的临床记忆量表。结果LD组与正常对照组在语言智商、操作智商、总智商[(86.23±10.65)分,(87.44±12.59)分,(84.09±13.96)分vs(102.27±10.21)分,(103.22±11.65)分,(103.28±9.88)分]及分测验值差异均有显著性(P<0.01);LD组儿童VIQ与PIQ相距一个标准差以上的比率明显高于对照组(2=9.29,P<0.01),也较MR对照组多(2=4.29,P<0.05)。LD组记忆商(MQ)明显低于正常对照组(P<0.01)。结论LD儿童智商、记忆商水平低于正常儿童,且存在明显智力结构发展不平衡。     

Modified Epworth Sleepiness Scale in Chinese children with obstructive sleep apnea: a retrospective study

Background and objective  The purpose of this study is to assess whether Chinese children with high apnea–hypopnea index (AHI) are sleepier by a modified Epworth Sleepiness Scale (ESS). Materials and methods  Records were retrospectively reviewed. We included children who were between 3 and 12 years old, admitted for overnight polysomnogram because of suspected obstructive sleep apnea syndrome (OSAS). A modified ESS was used to assess excessive daytime sleepiness (EDS) of the children. Results  One hundred ninety-two Chinese children were included. Children with high AHI, defined as AHI > 5.0, were sleepier than children with AHI less than or equal to 5. After adjustment by age, gender, and obesity, children with high AHI remained significantly sleepier. Modified ESS was significantly correlated with AHI (rho = 0.124, 95% CI = 0.004–0.281). Modified ESS score of >8 was the best cutoff point with the sensitivity and specificity of 0.29 and 0.91, respectively. The odds ratio of children with modified ESS > 10 having high AHI was 4.231 (95%CI = 1.248 to 14.338) and children with modified ESS > 8 had the highest odds ratio, 4.295(95%CI = 1.66 to 11.1), of having high AHI. Conclusion   Chinese children with high AHI appear to be sleepier than children with low AHI. Children with suspected OSAS and high modified ESS, i.e., ESS > 8, had significantly higher odds ratio of having high AHI. Increased sleepiness is a specific but not a sensitive symptom in snoring children with high AHI. Screening for EDS in snoring children may help us identify those with high AHI and prioritize the management of those children. All authors worked and the study was carried out in Kwong Wah Hospital in Hong Kong. There was no conflict of interest and no specific source of funding for the study.     

儿童无症状尿检异常IgA肾病的临床病理和预后分析

目的 探讨儿童无症状尿检异常的IgA肾病的临床病理特征和预后。 方法 对54例IgA肾病儿童的临床和病理特征进行分析。根据起病时有无临床症状分为无症状尿检异常组和有症状肾炎组。组织病理学分级参照Lee氏和Katafuchi氏半定量积分法。 结果 无症状尿检异常组18例，有症状肾炎组36例。有症状肾炎组尿蛋白量（24 h）明显高于无症状尿检异常组[（2.3±2.2） g比（0.4±0.3） g，P < 0.05]。无症状尿检异常的IgA肾病儿童表现为镜下血尿者，87％有尿微量白蛋白增高。无症状尿检异常IgA肾病患儿病理表现以Lee 氏Ⅰ~Ⅱ级为主，2例表现为Lee氏Ⅳ~Ⅴ级和 5例发生Katafuchi Ⅱ~Ⅲ级肾小管间质病变。有症状肾炎组Lee氏病理分级以Ⅱ~Ⅲ级为主，两者病理分级分布差异无统计学意义（P > 0.05）。全组患儿平均随访（26.9±8.8）月后，1例病理为Lee 氏Ⅴ级患儿进入终末期肾衰竭，其余患儿Scr均无升高1倍以上。 结论 无症状尿检异常的儿童IgA肾病虽临床症状轻微，但可出现病理损害严重的病例，并影响其预后。     

小儿输尿管开口异位的诊断和治疗(附22例报告)

目的探讨西部少数民族儿童行为问题及其与父母养育方式的关系,为少数民族地区开展心理健康教育提供理论依据。方法采用Achenbach儿童行为量表(CBCL)和儿童抚养行为问卷(CRPR)对415名苗族、土家族和侗族儿童进行调查。结果行为问题检出率为29.63%,其中男童为29.94%,女童为29.25%。男童检出率较高的因子为强迫、抑郁、交往不良、分裂样,女童检出率较高的因子为抑郁、分裂样强迫、多动。男童行为问题的绝大多数因子与父母的拒绝、惩罚定向呈显著的正相关,女童行为问题的多数因子与父母的拒绝呈显著正相关。结论黔东地区少数民族儿童行为问题显著高于全国水平,父母教养方式影响儿童的行为问题。     

间接免疫荧光法检测婴幼儿急性下呼吸道合胞病毒感染的特异性IgM

本文对1984年1～3月和1985年3～8月共107例急性下呼吸道感染的住院患儿,采用间接免疫荧光法检测其急性期血清抗RSV特异性IgM抗体,并与病毒分离和/或中和试验比较,敏感性为82.1％,特异性为71.8％。RSV感染患儿发病后3天内大多数病例即可从血清中检测出RSV-IgM,因此该法具有早期诊断价值。     

The Future Detection and Prevention of Institutional Abuse: Giving Children a Chance to Participate in Research

The involvement of children in research studies is historically fraught with difficulties. Experiments on children without their consent or knowledge have been carried out in the past and thus the need for stringent ethical control is undoubtedly necessary. However this paper argues that the need to protect children from unethical research has somehow become entwined in the web of secrecy that surrounds the very nature of child abuse. In the name of 'protection' are children in danger of not having their voice heard?

In the foreword to 'Listening to Children' (Alderson, 1995) Roger Singleton writes, 'much research is carried out on and about children, but seldom with children. Children themselves are often strangely silent'. This paper draws on recent literature on the institutional abuse of young people in residential care and the lack of voice that those abused in residential care have traditionally had, suggesting that their silence is not 'strange' but perhaps contrived.

This paper does not repeat the work of Alderson (1995) and make suggestions as to how research with children may best be carried out, but seeks to address the issues in relation to research with children who are in institutions.
