目的 评价不同复苏方法和不同药物、氧疗、物理疗法等对新生儿窒息复苏和复苏后的预防措施的有效性和安全性.方法 计算机检索Cochrane Library(2004年第3期),MEDLINE(1966～2002年) 关于新生儿窒息复苏时不同复苏方法、氧气的应用、以及不同药物、剂量、给药途径治疗和预防新生儿窒息的系统评价、随机和半随机对照试验.结果 正压通气时使用100%氧气和应用室内空气的复苏效果并无差异.胎粪污染羊水(MSAF)与较高的新生儿缺血缺氧性脑病(HIE)的发生率有关,而气管内有胎粪者无论稀稠均与胎粪吸入综合征发生率无关.窒息复苏后预防性给予亚低温疗法、抗惊厥药、纳洛酮、多巴胺等在降低新生儿病死率,继发HIE的严重程度等方面与对照组相比无显著差异.应用肺表面活性物质(PS)预防和治疗新生儿呼吸窘迫综合征(RDS),可减少死亡率和并发症.结论 应用PS预防和治疗RDS可明显减少新生儿死亡率,且胎龄lt;32周的早产儿预防用药比治疗用药效果更好;目前尚无充分证据证明窒息复苏后预防性给予亚低温疗法、抗惊厥药、纳洛酮、多巴胺等治疗的有效性.
Objective To evaluate the effect of vitamin A (Vit A) supplementation on the morbidity and mortality in children with infectious diseases. Methods We searched Cochrane Library (Issue 1, 2004), MEDLINE (1966-2004.3) and The PedsCCM Evidence-Based Journal Club (1992-2002). Relevant systematic reviews and randomized controlled trials (RCTs) of Vit A supplementation on morbidity and mortality in children with infectious diseases were obtained. Results We collected 107 studies and identified 13 systematic reviews or RCTs. The evidence showed that the effect of Vit A supplementation on morbidity and mortality was affected by the nutritional status of the children. Vit A supplementation given to Vit A deficient children could reduce the morbidity of diarrhea and mortality of measles. However, Vit A supplementation would increase the morbidity of diarrhoea and respiratory infections in children with sufficient nutrition. Conclusions The nutritional status of children correlates with morbidity and mortality of some infectious diseases, and the nutritional status and serum Vit A level should be evaluated before Vit A supplementation applied.
Objective To evaluate the diagnosis value of purified protein derivative (PPD) antibody tests in childhood tuberculosis. Methods We reviewed 126 cases of hospitalization children tested body fluid PPD antibody by Enzyme-Linked Immunosorbent Assay (ELISA). Twenty-two them were diagnosed with tuberculosis. We determined the sensitivity, specificity, diagnostic likelihood ratio, positive prognostic value, negative prognostic value, post-test probability, respectively. Results The following accuracy statistics for the PPD body liquid antibody tests in this study: sensitivity, 45.45%; specificity, 91.35%; diagnostic likelihood ratio positive, 5.25; diagnostic likelihood ratio negative, 0.597; positive predictive value, 52.63%; negative predictive value, 88.79% and post-test probability, 48.09% in 15% of prevalence. Conclusion This study shows that body fluid PPD tests have limited value for diagnosis of tuberculosis in pediatric tuberculosis. Clinic physicians should be wary of the positive results of body fluid PPD antibody tests. The value of diagnosis is related to prevalence of tuberculosis in the specific hospital.
Objective To assess the potential of ciprofloxacin to induce arthropathy in children and provide evidence for clinical practice. Methods We searched MEDLINE(1985- March 2006), The Cochrane Library (Issue 1,2006), EMBASE(1985 to March 2006) and CBMdisk(1990 to March 2006) for randomized controlled trials (RCTs) involving the safety of ciprofloxacin in pediatrics. We assessed the methodological quality of the studies identified. RevMan 4.2 was used for meta-analysis. Results Seven RCTs met the inclusion criteria. Compared with the control group, the combined rate of arthralgia did not increase compared to ciprofloxacin. The relative risk was 0.98, 95% confidence interval 0.65 to 1.48. No studies reported joint pathology and cartilage lesions on radiographic imaging, ultrasound or magnetic resonance imaging in the pediatric population. Conclusion Based on the results of the review and the meta-analysis, there is no evidence that using ciprofloxacin in the pediatric population is associated with clinical arthropathy. Further well-designed clinical studies should be performed to assess the long-term consequences of the use of ciprofloxacin in children.
ObjectiveTo investigate the high-risk factors for death in infants with severe pneumonia. MethodsWe analyzed hospitalized infants and young children diagnosed with severe pneumonia from January 2011 to December 2013, and investigated the risk factors for death. ResultsA total of 1 411 infants with severe pneumonia were included in the analysis. The mortality rate was 3.12%. In single factor analysis, the following factors were significant:age, severe infection, artificial feeding, congenital heart diseases, bad habitation, repeated infection history, surgical history, multi-organ dysfunction, internal environment disorder, multiple drug-resistant strains infection. The results of Logistic multiple regression analysis showed that there were statistical significance in severe infection, repeated infection history, Multiple drug-resistant strains infection, multi-organ dysfunction, and internal environment disorder. ConclusionInfants with severe pneumonia should be intensively monitored and actively treated for reducing the mortality rate if they have one of the following high-risk factors:age, congenital heart diseases, repeated infection history, multiple drug-resistant strains infection, surgical history, multi-organ dysfunction, and internal environment disorder.
ObjectiveTo explore the clinical features and outcomes of relapsed acute lymphoblastic leukemia (ALL) in children. MethodsThirty-two ALL children treated in line with the Chinese Child Leukemia Cooperative Group ALL-2008 protocol with a relapse of the disease during January 2009 to May 2013 were enrolled into this study. Their clinical features and outcomes were retrospectively analyzed and compared with those who achieved continuous complete remission (CCR). ResultsThere were 32 relapsed cases among 319 newly diagnosed ALL cases (excluding infantile ALL) during the study period, with a relapse rate of 10%. In the relapse group, the proportions of patients with peripheral blood white blood cell count ≥50×109/L at diagnosis, positive BCR/ABL fusion gene, poor prednisone response, high risk stratification, and who failed to achieve bone marrow complete remission at d15 and d33 of induction chemotherapy, were significantly higher than those in the CCR group (all P<0.05). Multivariate analysis showed that high risk stratification was an independent risk factor for relapse (OR=3.529, P=0.002). In terms of site of relapse, isolated marrow relapse, isolated central nervous system relapse, isolated testicular relapse and combined relapse accounted for 23 (72%), 6 (19%), 1 (3%) and 2 (6%), respectively. As regard to the time of relapse, 26 cases (81%), 4 cases (13%) and 2 cases (6%) were categorized as very early relapse, early relapse and late relapse respectively. Twenty-four children with relapsed ALL received re-induction chemotherapy. Among them, 16 cases (67%) achieved second complete remission. Nevertheless, 9 cases ultimately suffered second relapse. ConclusionRelapse, which occurs more commonly in high risk ALL group, still remains a great challenge in clinical practice. Relapsed ALL, especially those with very early and early marrow relapse, has poor prognosis.
ObjectiveTo build the list of appropriate dosage forms and specifications of essential medicines for children which is subsistent abroad and absent in China. MethodsBased on the authoritative data and expert consultation, we established the selection methodology which included the standard of essential medicine for children, the standard of appropriate dosage for children, the standard of appropriate specifications for children, the standard of urgent classification, the standard of urgent level. ResultsThe list of appropriate dosage forms and specifications included 61 medicines which included 20 dosage forms and 112 specifications. 112 specifications included 27 specifications which belong to level Ⅱ, and 85 specifications which belong to level Ⅲ. ConclusionThe established list can be included by the green channel.
Objective To investigate baseline data of the current status of patients in China, and thus to develop strategies to get patients involved in evidence-based medicine (EBM). Method 300 questionnaires with 17 questions were distributed to the in-patients in West China Hospital, Sichuan University. Statistical software such as SPASS 10. 0 was applied to analyze all the data. Results No patients had ever heard of EBM. Most patients did not know much information about their diseases, but had a b desire to learn from their doctors. Most of them would like to be involved in the treatment decision-making and hoped that their doctors would care about their preference. The cost and the effectiveness of the treatment were the most important issues that patient concerned about. Conclusions The dissemination of health information is very limited for patients and the accessibility of effective health information depends much on the direct communication with their doctors. Promoting patient involved in EBM is fairly a hard and long way to go based on the actual reality of the country.
