Heterogeneity of FeNO response to inhaled steroid in asthmatic children

Background Nitric oxide in exhaled air is regarded as an inflammation marker, and may be used to monitor the anti‐inflammatory control from inhaled corticosteroids (ICSs). However, this response to ICSs exhibits a heterogeneous pattern. Objective The study aimed to describe the independent variables associated with the heterogeneity in the response of exhaled nitric oxide to ICSs. Methods Exhaled nitric oxide (FeNO), lung function, bronchial hyper‐responsiveness (BHR), specific IgE to common inhalant allergens, blood eosinophils, other atopic manifestations and variants in nitric oxide synthethase 1 (NOS1) gene were studied in a double‐blind, placebo‐controlled crossover comparison of budesonide (BUD) Turbohaler 1600 mcg daily vs. placebo in asthmatic schoolchildren. Results Forty children were included in the study from a screening of 184 asthmatic children with moderately persistent asthma, well controlled on regular BUD 400 mcg daily: 20 children with normal FeNO and 20 with raised FeNO. FeNO, BHR and forced expiratory volume in 1 s improved significantly after BUD 1600 mcg (BUD1600). However, FeNO after ICS treatment exhibited a Gaussian distribution and FeNO was significantly raised in 15 children. Allergy and BHR, but none of the other independent variables under study were significantly related to FeNO after BUD1600. Conclusion Exhaled nitric oxide exhibited a heterogeneous response to ICS in asthmatic schoolchildren. Allergy and BHR were driving FeNO level independently of high‐dose steroid treatment. This should be considered when using FeNO for steroid dose titration and monitoring of ICS anti‐inflammatory control in asthmatic children.     

孤独症广泛表型的临床调查

目的:调查孤独症先证者家系中孤独症广泛表型(BAP)及其主要表现,统计其发生率,为进一步的神经心理和遗传研究建立基础.方法:使用家系调查表和Bolton孤独症广泛表型的操作定义手册,对75例孤独症先证者的家系进行筛查,对符合BAP定义的家属进行总结和分类.结果:75例先证者的家系亲属中共有42例符合BAP 的诊断,他们以社交缺陷表现为主,其次为语言发育障碍,以行为怪异为主要表现的最少.结论:BAP在孤独症家系中的存在对遗传学的研究可能提供一条有用的途径,有必要做进一步的研究和探讨.     

55对独生与多生子女MMPI配对研究

按同班、同性别、学号最邻近１：１配对原则从１６～１８岁青少年中选出５５对（男３４，女２１）独生与多生子女作为被试。ＭＭＰＩ测试结果：各量表Ｔ值，男性两组间无显著性差异；女性Ｋ量表独生组高于多生组，Ｄ和Ｓｉ两量表独生组低于多生组，其余１１项量表两组间亦无显著性差异。提示：总体上独生与多生子女间无显著个性差异，但独生女与多生女间有所差别。     

对Bem性别角色量表的考察与修订

目的：对在性别角色研究中使用得最为广泛的工具-Bem量表进行介绍，考察它在中国文化下的信、效度并进行修订。方法：选取两个城市三所大学中的340名本科生为被试。经过项目分析、因素分析等统计方法，对构成量表的条目进行删除和保留。结果：最后由14项男性化条目和12项女性化条目构成新的Bem量表简本。结论：修订后的Bem量表在信、效度上有了明显的提高，可以成为进一步研究的工具。     

缺铁性贫血对学龄儿童某些认知能力影响的研究

本文采用双盲法对 IDA 和 NIDA学龄儿童各61名进行了认知能力测验及铁治疗前后的动态比较。结果表明:IDA 儿童识记再认、字母匹配反应时、数字扫描记忆和一般推理能力测验成绩较 NIDA 儿童差。经铁治疗的IDA 儿童,注意、短时记忆和心理动作反应速度均有明显提高。但对较高级认知能力的改善不明显。     

A case of broken bones and systems: The threat of irresponsible testimony

A 2‐month‐old healthy baby presented to the emergency room with an arm that was not moving and was found to have multiple and extensive fractures of her long bones. An extensive medical work‐up was done, and the hospital's multidisciplinary child abuse team was consulted, including child protection, genetics, radiology, and general pediatrics. It was determined that the history, clinical findings, radiographic findings, and laboratory findings were consistent with child abuse. Child protection services removed the child from the home, and for the next 10 months, the infant was well, and did not sustain a single new fracture. At a civil proceeding to determine the infant's custody, an expert witness for the defense concluded that the child had hypermobile Ehlers‐Danlos syndrome and low vitamin D. He stated that because of these conditions, the baby was vulnerable to fractures with routine handling. This is a personal story of a clinical geneticist who explored fracture fact versus fracture fiction and learned about the difference between responsible and irresponsible testimony. This story gives insight into how physicians can prepare to transition from the clinic to the courtroom. It is also a story about how medical experts must and should remain unbiased, evidence‐based, and committed to accuracy and truth.     

A systemic perspective on children’s emotional insecurity in relation to father: links to parenting,interparental conflict and children’s social well-being

ABSTRACT

Focusing on the father-child-relationship in a family systems perspective, this paper investigates longitudinal links of parenting, interparental conflict, and positive regard by both parents, to their emotional insecurity with father and mother. Furthermore, to clarify fathers’ contribution to children’s social development, aspects of the relationship to both parents are jointly considered. The sample was drawn from the German family panel pairfam and included 372 family triads with parents’ and children’s self-reports. Findings revealed consistent associations between interparental conflict and lack of positive regard and emotional insecurity, while parenting had no independent links with children’s emotional insecurity or social adjustment. Controlling for the stability of child outcomes, interparental conflict predicted children’s lower prosocial behavior and higher peer rejection. In addition, peer rejection was predicted by children’s emotional insecurity with father. The findings are in line with the emotional security hypothesis and highlight the importance of the father-child-relationship for developing positive peer relationships.     

Regulation of cognitive activity and early communication development in young autistic, mentally retarded, and young normal children

Based on the Piagetian framework, this study examined regulation of cognitive activity and developmental communication profiles and their interrelationship in groups of autistic, mentally retarded, and normal children of comparable overall, verbal, and oculo-manual developmental ages (from 6 to 24 months). Regulation of activity was assessed with both an object permanence test and an original behavior grid, and development of communication skills with the Guidetti-Tourrette scales (French adaptation of the Seibert-Hogan scales). The results showed evidence of certain types of dysregulation of cognitive activity and a general delay in communication ability in autistic children compared to the other two groups. Moreover, although the intensity of some of these disorders decreased in relation to the developmental levels of social interaction and joint attention in normal children, they were related to both high and low levels of development of social interaction only in autistic children. These findings raise the hypothesis of a relationship between a disorder of disengaging from an activity and developmental levels of social interaction noted at two transitory periods of early development (12 and 24 months) only in children with autism. Developmental and neuropsychological interpretations of this particular pattern are proposed.
