Clinical and laboratory characteristics of 75 patients with specific polysaccharide antibody deficiency syndrome.

BACKGROUND: There are limited studies of large cohorts of patients with specific polysaccharide antibody deficiency (SPAD) syndrome. OBJECTIVE: To study the clinical and laboratory characteristics of patients with specific polysaccharide antibody deficiency syndrome. METHODS: We retrospectively studied 75 patients with total IgG levels of at least 500 mg/dL and fewer than 9 of 12 responses to vaccination with pneumococcal vaccine polyvalent. Exclusion criteria included an IgG level less than 500 mg/dL, established immunodeficiency syndrome, and secondary immunodeficiency. RESULTS: The most common clinical presentation was frequent infections (n = 69; 92%), including sinusitis (n = 53; 77%), pneumonia (n = 29; 42%), ear infections (n = 18; 26%), and bronchitis (n = 19; 28%). Other presentations were systemic infections (n = 5; 7%), autoimmune or rheumatic diseases (n = 6; 8%), and chronic diarrhea (n = 4; 5%). The median IgG2 level of patients with no response to pneumococcal vaccine polyvalent tended to be lower than that of patients with at least 1 response (150 vs 193 mg/dL, respectively; P = .06). There was no association between total IgG level (categorized as 500-600 or > or = 600 mg/dL) and frequency of infection (P = .43). Patients with fewer responses to pneumococcal vaccine polyvalent and a higher frequency of infections were more likely to receive intravenous immunoglobulin (IVIG) therapy (P = .01 and .003, respectively). Treatment with IVIG significantly reduced the number of infections (P < .001). CONCLUSION: Patients with no response to pneumococcal vaccine polyvalent tended to have lower IgG2 levels; those with fewer responses were more likely to receive IVIG therapy.

碘盐预防碘缺乏病效果的系统评价

目的 系统评价碘盐预防碘缺乏病的效果.方法 计算机检索Cochrane Central Register of Controlled Trial(Cochrane图书馆2009年第4期)、MEDLINE(1966～2009.12)、Ovid Medline(1966～2009.12)、Embase数据库(1986～2009.12)、CBM光盘版(1978～2009.12)、CNKI(1980～2009.12)以及VIP(1989～2009.12),并且追查纳入文献的参考文献.按纳入和排除标准由2名评价者独立选择试验、提取资料,交叉核对并进行方法学质量评估,对同质研究采用RevMan 5.0软件进行Meta分析.结果 共纳入5篇随机对照研究,842例研究对象,儿童组碘盐和空白食盐的甲肿率结果比较无统计学意义[OR=1.19,95%CI(0.74,1.92)],成人组碘盐和其他形式的补碘措施比较,碘盐组甲肿率、甲状腺体积均低于其他形式的补碘组.结论 碘盐能显著改善成人的碘营养状况,副作用还需大量高质量的随机对照试验来验证.     

Analysis of the Surface Ozone During Summer and Autumn at a Coastal Site in East China

The levels and temporal variations of surface ozone at a coastal site in East China during summer and autumn were analyzed and the influences of meteorological parameters on ozone were investigated. An inland city was chosen as a comparison site. The main results and conclusions of this study are: (1) ozone pollution, with a maximum 1 h concentration of 150.98 ppbv, was severe during summer and autumn at the coastal site; (2) the ozone level was obviously higher at the coastal site than that at the inland site in September; (3) besides temperature and solar radiation, sea-land breeze circulation is an important factor influencing the ozone level at the coastal site, and sea breeze often induce high ozone levels (the average ozone concentration for sea breeze was about 13 ppbv higher than that for land breeze).     

注意缺陷多动障碍儿童初始沙盘游戏对照研究

目的 探究注意缺陷多动障碍儿童初始沙盘游戏特征.方法 对29名注意缺陷多动障碍儿童和29名正常儿童进行沙盘游戏干预,对照分析两组儿童初始沙盘游戏主题及沙具使用情况.结果 注意缺陷多动障碍儿童沙盘游戏主题较正常儿童混乱无序,两组比较差异有统计学意义(χ2=22.58,P<0.00);两组儿童在沙具使用方面比较差异无统计学意义(均P>0.05).结论 注意缺陷多动障碍儿童沙盘游戏具有独特特征以及一定的临床诊断筛查价值.

上睑下垂的术前评估及改良提上睑肌缩短术矫治的疗效评价

目的评价改良提上睑肌缩短术矫治上睑下垂的效果。方法采用改良提上睑肌缩短术[此改良术式与常规术式不同之处在于增加分离提上睑肌腱膜的长度(22mm)和宽度(16mm),腱膜在睑板上固4对缝线,以增加其牢固度],共治疗上睑下垂57例68眼,其中轻度13例13眼,中度38例47眼,重度6例8眼。结果术后4～36个月随访,治愈48例59眼,欠矫9例9眼,无过矫病例。结论该提上睑肌缩短术与常规手术比较有改进,术后的睑缘高度易保持在上方角膜缘,弧度与健侧对称,不易形成眼角畸形,能较好提高矫治效果。
