Stomach versus sigmoid colon in children undergoing major reconstruction of the lower urinary tract

A review of 50 patients who underwent intestinocystoplasty (ICP) or gastrocystoplasty (GCP) replacement at our department during an 8-year period is presented. The most common diagnoses were neurogenic bladder and bladder exstrophy. A total of 48 patients underwent augmentation cystoplasty and 2 had total bladder replacement. Mean follow-up time was 42 months. The clinical and metabolic aspects of the two types of ICP are reported. Hyperchloremic acidosis requiring therapy was not encountered, although mild degrees were seen after sigmoid augmentation in 36% of patients. A dysuria-hematuria syndrome (DHS) was seen in 50% of the patients who underwent GCP. Operative mortality rate was nil. Significant surgical complications occurred in 36% of the patients. The overall success rate for ICP and GCP in this series was 79.15%. ICP gives effective results when used to increase the compliance of the lower urinary tract, but problems related to electrolyte absorption, stones, and mucus production are often encountered. In GCP electrolyte absorption is practically eliminated, so that this technique can be used in patients with renal damage. In addition, patients with a normal bladder plate (bladder exstrophy) can achieve normal voiding with time. The authors believe that patients must be made aware of the possibility of DHS and that this syndrome needs further investigation.     

A Competency-based Model of Child Depression: A Longitudinal Study of Peer, Parent, Teacher, and Self-evaluations

In a two-wave longitudinal study of third and sixth graders ( N = 617), we obtained self-reports of depression and peer, teacher, parent, and self-reports of competence in five domains: academic, social, attractiveness, conduct, and athletic. Competency evaluations by others predicted change in self-perceived competence over time for girls, but not for boys. Depression predicted change in self-perceived competence over time for boys but not for girls. Among girls, the relative importance of parent, teacher, and peer appraisals shifted from third to sixth grade. For both boys and girls, self-perceptions of competence predicted change in depression scores over time. Furthermore, self-perceived competencies mediated the relation between competency appraisals by others and children's self-reported depression. Results are interpreted in light of a competency-based model of child depression.     

Thyroid function in a population of children with attention deficit hyperactivity disorder

To determine the prevalence of thyroid hormone abnormalities and generalized resistance to thyroid hormone in a population of children with attention deficit hyperactivity disorder (ADHD) as compared to reference ranges determined from a control population and hence to determine if routine thyroid hormone screening in children with non-familial ADHD is indicated.

Method:

Children attending the State Child Development Centre in Perth, Western Australia with ADHD, as defined by the Diagnostic and Statistical Manual of Mental Disorders (fourth edition) provided the study population. The control population consisted of 353 normal children with a history of allergy in whom radioallergosorbent (RAST) testing was being performed.

Results:

The prevalence of thyroid hormone abnormalities in the study population was 2.3% (95% CI 0.6%, 5.7%). There were no cases of generalized resistance to thyroid hormone. The prevalence of thyroid hormone abnormalities in the general population of children and adolescents has been reported to vary between 1 and 3.7%.

Conclusion:

Routine thyroid hormone screening is not indicated in children with non-familial ADHD.     

环枢关节紊乱症的临床研究

环枢关节紊乱症，从发病机理到临床表现，乃是颈椎病中较复杂的疑难顽症。用常规诊治方法，疗效不佳。本研究提出新的诊断依据与治疗方法，对３２０例病者随机分为治疗组１６６例（采用改进的诊治方法），对照组１５４例（用常规诊治方法）对照进行疗效观察。结果显示：治疗组治愈率与总有效率及康复率均高于对照组。有非常显著差异，Ｐ＜０．０１。而疗程较对照组短。环枢关节紊乱症的临床研究有利于颈椎病诊治水平的提高，运用于临床，疗效好，效益高，具有推广应用价值。     

Epstein-Barr Virus Polymerase Chain Reaction and Serology in Pediatric Post-Transplant Lymphoproliferative Disorder: Three-Year Experience

To assess whether the semiquantitative peripheral blood Epstein-Barr virus (EBV) polymerase chain reaction (PCR) test correlates with post-transplant lymphoproliferative disorder (LPD), we compiled the results of the test done over a 3-year period ending July 1997. Six hundred seventy-six tests were done on 185 patients. Four hundred-thirty tests (63%) were negative, 167 (25%) were weak positive, 67 (10%) were moderate positive, and 12 (2%) were strong positive. Twelve of the patients developed a lymphoproliferative disorder (LPD) during this time. The EBV PCR tests proximate to the diagnosis of LPD in the 12 patients with EBV-positive LPD were 6 strong positive, 5 moderate positive, 1 weak positive. No patient with LPD had a negative result at diagnosis. Stated another way, 6/12 (50%) of strong-positive PCR tests, 5/67 (7%) moderate-positive tests, and 1/167 (.6%) of weak-positive tests correlated with LPD. Serologic evaluation for EBV done on 7 patients at the time of LPD showed low serologic responses in 5 of the 7 patients. The EBV PCR temporally associated with the serology indicated moderate to large viral burdens. In each patient evaluated serially, the EBV PCR test rose before the diagnosis of LPD and fell with treatment for the disorder. In conclusion, the EBV PCR test may be used as an adjunct to the diagnosis of patients with LPD and may be used to monitor response to therapy for the disorder.

Diagnostic Rules for Children with PDD-NOS and Multiple Complex Developmental Disorder

This study was designed to examine the classification performance of diagnostic rules for pervasive developmental disorder not otherwise specified (PDD-NOS) and multiple complex developmental disorder (McDD), with clinical diagnosis as the gold standard. McDD is an heuristic concept of a developmental disorder characterised by social impairments, affective dysregulation, and thought disturbance. Detailed information on the symptoms, reliably extracted from the charts of 103 children with PDD-NOS and McDD, 32 with autistic disorder, and 96 with non-PDD disorders, was used to determine the presence of the DSMIV criteria of autistic disorder and the criteria of McDD. A scoring rule for PDD-NOS based on a short set of seven DSM-IV criteria with a cut-off point of three items and one social interaction item set as mandatory had the best balance between high sensitivity and high specificity. The most effective and simple rule based on McDD criteria had a cut-off of three items, out of six items of anxieties and thought disturbance.     

Disentangling the Overlap between Tourette's Disorder and ADHD

Objective : To identify similarities and differences in neuropsychiatric correlates in children with Tourette's syndrome (TS) and those with ADHD. Method : The sample consisted of children with Tourette's syndrome with ADHD( N = 79), children with Tourette's syndrome without ADHD ( N = 18), children with ADHD ( N = 563), psychiatrically referred children ( N = 212), and healthy controls ( N = 140). Results: Disorders specifically associated with Tourette's syndrome were obsessive compulsive disorder (OCD) and simple phobias. Rates of other disorders, including other disruptive behavioral, mood, and anxiety disorders, neuropsychologic correlates, and social and school functioning were indistinguishable in children with Tourette's and ADHD. However, children with Tourette's syndrome plus ADHD had more additional comorbid disorders overall and lower psychosocial function than children with ADHD. Conclusions: These findings confirm previously noted associations between Tourette's syndrome and OCD but suggest that disruptive behavioral, mood, and anxiety disorders as well as cognitive dysfunctions may be accounted for by comorbidity with ADHD. However, Tourette's syndrome plus ADHD appears to be a more severe condition than ADHD alone.     

Reflex sympathetic dystrophy in a 12-year-old twin with comorbid conversion disorder in both twins

A case of reflex sympathetic dystrophy is presented in a 12-year-old girl with comorbid conversion disorder. Her identical twin also had a conversion disorder. This is the first reported case of coexistence of reflex sympathetic dystrophy and conversion disorder. It is important for clinicians to be aware that these conditions may coexist since the presentation of symptoms differ, even though there are shared features of treatment.     

孕激素与围绝经期情绪障碍相关性的探讨

目的：探索孕激素在女性围绝经期情绪障碍中的作用.方法：研究对象以抑郁为主伴或不伴焦虑的围绝经期女性57例,及参加体检的、经Zung氏焦虑抑郁自评量表筛选后无抑郁焦虑症状群的围绝经期健康女性37例,两组年龄范围均介于40～60岁.主要评定工具为HAMD、HAMA、SAS、SDS等量表,并于入院后次晨空腹抽血检测孕激素.结果：HAMD、HAMA评分在女性围绝经期情绪障碍组和健康对照组之间存在着统计学差异（P＜0.01）;情绪障碍组的孕激素水平虽然略高于健康对照组,但两者之间差异无统计学意义（P＞0.05）;情绪障碍组的孕激素与HAMD评分之间没有相关性,而与HAMA评分之间有低度相关性（P＜0.05）.结论：孕激素在女性围绝经期情绪障碍的发生、发展中可能发挥着一定的作用.
