Objective To assess the effectiveness of intravenous immunoglobulin G (IVIG) in reducing the need for exchange transfusion in neonates with proven haemolytic disease due to Rh and/or ABO incompatibility. To evaluate the effectiveness of IVIG in reducing the duration of phototherapy and hospital stay. Methods We electronically searched CENTRAL, MEDLINE (1966 to May 2008), EMBASE (1992 to May 2008), CBMdisc (November 1979 to May 2008), and also checked the reference lists of all papers identified. According to the Cochrane Handbook for Systematic Reviews of interventions, randomized controlled trials comparing IVIG and phototherapy with phototherapy alone in neonates with Rh and/or ABO incompatibility were identified and analyzed. Results Six RCTs were included. The meta-analysis showed that, IVIG can significantly decrease the requirements of exchange transfusion (RR=0.27, 95%CI 0.18 to 0.42), the duration of hospitalization (WMD= –1.11, 95%CI –1.60 to –0.63) and the duration of phototherapy (WMD= –0.82, 95%CI –1.16 to –0.47). Conclusions Intravenous immunoglobulin (IVIG) is recommended for treating hemolytic disease of the newborn because it is effective in decreasing the requirements of exchange transfusion, the duration of hospitalization and phototherapy. Well designed studies with large sample in multi-center are required for further proving.
Objective To investigate the etiological and clinical characteristics of the outbreak of hand-foot-mouth disease (HFMD) in Chengdu in 2008. Methods A retrospective analysis was conducted to investigate 482 children with hand-foot-mouth disease in Chengdu from January to December 2008 in terms of epidemiology and clinical characteristics. Results Among the 482 children, 76.14% of the cases were infants, and male children numbered more than female ones. The proportion in the urban area was higher than that in the rural area. May to July was the peak epidemic period. Skin rash and fever were major clinical manifestations. Three cases were diagnosed as viral encephalitis. Conclusion The incidence of hand-foot-mouth disease is related to age and season. Effective prevention measures and isolated treatment are critical for prevention and therapy.
Objective To investigate the incidence of urolithiasis in the children who ingested milk powder tainted with melamine in the Chengdu area. Methods A total of 5 795 infants were screened for urolithiasis by ultrasound examination from September 17, 2008 to December 9, 2008. The data were analyzed using SPSS 13.0 software.Results Twenty-four children were diagnosed with urolithiasis with an incidence of 0.41%, including 12 males and 12 females. The mean age of those children with urolithiasis was 2.35±1.68 years old. No significant difference was shown in the incidence of urolithiasis between males and females (Pgt;0.05). The incidence of urolithiasis in the infants aged 0-3 was significantly higher than that in the children who were more than 3 years old (Plt;0.05). Conclusion The incidence of urolithiasis in the infants aged 0-3 in Chengdu and the surrounding areas is relatively high. Further data should be collected during the follow-up of these cases.
Objective To investigate the effects of montelukast ( MK) on the airway inflammation and the risk of the recurrence of wheezing in the treatment of infants with RSV bronchiolitis.Methods 60 infants ( aged 6-24 months) with RSV bronchiolitis admitted between December 2010 and December 2011 were recruited in the study. They were randomly assigned into a conventional group and a MK group ( n =30 in each group) . All patients received conventional treatments including inhalation of budsonide and so on.The subjects in the MK group received oral montelukast ( 4 mg qn for 12 weeks) additionally. The levels of serum cysteinyl leukotrienes ( CysLTs ) , total immunoglobuline E ( T-IgE) , eosinophil cationic protein ( ECP) and fractional exhaled nitric oxide ( FeNO) were assayed before and after the treatments. Thenumber of recurrence of wheezing was recorded through outpatient and telephone follow-up for 12 months. 30 healthy infants participating the health examination in outpatient were selected as control, and those who got atopic disease or respiratory tract infections recently were excluded. Results The levels of CysLTs, ECP and FeNO of the patients with RSV bronchiolitis before treatment were significantly higher than those in the normal control group, and the levels of CysLTs and FeNO were significantly decreased after treatment ( P lt;0. 05) . The levels of CysLTs and FeNO after treatment in the MK group was significantly lower than those in the conventional group. The level of ECP was significantly decreased after treatment in the MK group ( P lt;0. 05) ,·186· Chin J Respir Crit Care Med, March 2013 , Vol. 12 , No. 2 http: / /www. cjrccm. com which was not significantly changed in the conventional group( P gt; 0. 05) . The number of recurrence of wheezing in the MK group was more less that that in the conventional group ( P lt; 0. 05) . Conclusion Maintenance treatment with montelukast after the treatment of the acute phase of bronchiolitis can prevent recurrence of wheezing by suppressing airway inflammation in infants with RSV bronchiolitis.
