Rational approaches to the neurobiologic study of youth at risk for bipolar disorder and suicide

Objectives:  The aims of this paper are to provide an overview of neuroimaging findings specific to bipolar disorder and suicide, and to consider rational approaches to the design of future in vivo studies in youth at risk.
Methods:  Neuroimaging and related neurobiological literature pertaining to bipolar disorder and suicide in adult and pediatric samples was reviewed in a non-quantitative manner.
Results:  Specific structural and functional brain findings in bipolar disorder are described, where possible in the context of relevant current neurobiological theories of etiology. Diagnostic and prognostic implications are discussed.
Conclusions:  The simultaneous use of complementary neurobiological approaches may be a powerful way of identifying and validating factors reliably associated with bipolar disorder and suicide. A profile of neurobiological markers with which to screen for bipolar disorder and suicide risk may provide for earlier and more accurate diagnosis, perhaps even in the pre- or subsyndromal stages in high-risk youth.     

Recovery and Utilization of Deceased Donor Kidneys from Small Pediatric Donors

The optimal use of kidneys from small pediatric deceased donors remains undetermined. Using data from the Scientific Registry of Transplant Recipients, 2886 small (< 21 kg) pediatric donors between 1993 and 2002 were identified. Donor factors predictive of kidney recovery and transplantation (1343 en bloc; 1600 single) were identified by logistic regression. Multivariable Cox regression was used to assess the risk of graft loss. The rate of kidney recovery from small pediatric donors was significantly higher with increasing age, weight and height. The odds of transplant of recovered small donor kidneys were significantly higher with increasing age, weight, height and en bloc recovery (adjusted odds ratio = 65.8 vs. single; p < 0.0001), and significantly lower with increasing creatinine. Compared to en bloc, solitary transplants had a 78% higher risk of graft loss (p < 0.0001). En bloc transplants had a similar graft survival to ideal donors (p = 0.45) while solitary transplants had an increased risk of graft loss (p < 0.0001). En bloc recovery of kidneys from small pediatric donors may result in the highest probability of transplantation. Although limited by the retrospective nature of the study, kidneys transplanted en bloc had a similar graft survival to ideal donors but may not maximize the number of successfully transplanted recipients.     

Evaluation of CHIP (iproplatin) in recurrent pediatric malignant solid tumors

CHIP (325 mg/M²), a second generation cisplatin derivative, was administered intravenously every 3 weeks to 85 pediatric patients with recurrent sarcomas (19), osteosarcomas (20), neuroblastoma (23), germ cell tumors (10), and other malignant tumors (7). Thirty-eight of them had been previously exposed to cisplatin. Partial remissions were only observed in 3 of 23 (13% SE=7%) patients having neuroblastoma. Severe thrombocytopenia (65%) and neutropenia (35%) were the dose limiting factors.

做好当前临床外科教学工作的思考

应从提高教师队伍素质、提倡主动式教学、专科教育、指导学生处理好医患关系、提高法律意识和自我保护意识、制定统一的教学内容和目标等方面，做好临床教学工作。     

不同层次护生对临床教学质量的评价

目的分析不同层次护生对临床教学质量评价的差异,以便采取有针对性的教学方法.方法护生在每个科室实习结束后,采用自行设计的临床教学评价表对每名护生进行问卷调查,然后分别从中专、大专、本科护生填写的调查表中各随机抽取30%进行分析.结果对病房教学氛围和护士长教学管理的评价,本科与中专、大专护生间比较,差异有显著性意义(均P<0.05),中专与大专护生间无差异(P>0.05);对带教老师的评价,本科与中专、大专与中专护生间均差异有显著性意义(P<0.01,P<0.05),本科与大专间无差异(P>0.05).结论不同层次护生对临床教学质量评价的侧重点不同,本科生对病房教学氛围及护士长教学管理的要求较高,大专生次之.在临床教学中应根据护生的学历层次,采取有针对性的教学方法,以便不断提高临床教学质量.     

Tetrabenazine therapy of pediatric hyperkinetic movement disorders.

Tetrabenazine (TBZ), a presynaptic dopamine depletor and postsynaptic dopamine receptor blocker, is widely used for the treatment of hyperkinetic movement disorders in adults. However, reports of its use in children are limited. We review the efficacy and tolerability of TBZ therapy in 31 children with hyperkinetic movement disorders refractory to other medications. TBZ was effective in reducing the severity of movement disorders resistant to treatment with other medicines. When compared to adult patients, pediatric patients required higher doses. Side effects were similar to the adult population; however, children had a lower incidence of drug-induced Parkinsonism.
