钩虫病感染者免疫球蛋白水平、临床特点及胃肠镜下形态分析

目的分析钩虫病感染者血清免疫球蛋白(Ig)A、IgG、IgM和IgE水平,临床特点及胃肠镜下形态。方法分析16例钩虫病感染者的临床资料,观察患者的临床表现、Ig水平、血常规检查结果、胃肠镜检查结果及治疗结果。结果 16例患者的IgE水平明显高于正常参考上限值;IgA、IgG、IgM水平与正常参考上限值比较,差异不明显。经诊断患者的钩虫分布情况:十二指肠降部8例(50.00%),十二指肠球部5例(31.25%),回肠末端3例(18.75%),升结肠1例(6.25%),其中十二指肠及回肠末端均见钩虫者1例(6.25%)。所有患者均予阿苯达唑片驱虫治疗,治疗后1个月复查见贫血得到纠正,消化道症状得以缓解,复查胃肠镜未见虫体,均治愈。结论钩虫病感染者的IgE水平明显升高,胃肠镜检查是确诊钩虫病的重要手段,尤其是要加强对十二指肠降部的检查,并在确诊后及时给予正规治疗措施。     

Sleep time and sleep-related symptoms across two generations – results of the community-based RHINE and RHINESSA studies

Study objectivesTo analyze the association between sleep-related symptoms and sleep length in parents and their children in relation to other risk factors in both generations.MethodThe participants were parents (n = 5,855, age 54.3 ± 6.5 years, 45.2% men) who participated in the community-based Respiratory Health in Northern Europe (RHINE) study and one random member of their adult offspring (n = 5,855, age 30.2 ± 7.7 years, 41.5% men) who participated in the Respiratory Health in Northern Europe, Spain and Australia (RHINESSA) study. Both generations responded to identical questionnaires on sleep symptoms, including difficulty initiating sleep (DIS), difficulty maintaining sleep (DMS), early morning awakening (EMA), snoring, nocturnal sweating, nocturnal gastroesophageal reflux (nGER), sleep time and excessive daytime sleepiness (EDS). Insomnia was defined as either, or both, DIS and DMS in combination with EDS.ResultsAll sleep variables except nocturnal sweating were more common in offspring whose parents had reported the same symptom. After adjusting for age, gender, BMI, smoking, physical activity, education, center and parents' total number of children, there were independent associations between sleep symptoms in parents and offspring for DIS (adj. OR, 95% CI: 1.52, 1.20–1.93), DMS (1.34, 1.15–1.56), snoring (1.45, 1.15,1.83), nGER (1.65, 1.15–2.37), insomnia (1.39, 1.13–1.73), short sleep time (<6 h/night) (2.51, 1.72–3.68) and EDS (1.48, 1.26,1.72). There were no independent relationships between symptoms in parents and offspring for EMA, nocturnal sweating or long sleep time (>9 h/night).ConclusionThe familiar aggregation of many sleep disturbances was not explained by investigated lifestyle and environmental factors. This supports a heritable factor in sleep problems.     

Prevalence and correlates of mild cognitive impairment among diverse Hispanics/Latinos: Study of Latinos-Investigation of Neurocognitive Aging results

IntroductionWe estimated the prevalence and correlates of mild cognitive impairment (MCI) among middle-aged and older diverse Hispanics/Latinos.MethodsMiddle-aged and older diverse Hispanics/Latinos enrolled (n = 6377; 50–86 years) in this multisite prospective cohort study were evaluated for MCI using the National Institute on Aging–Alzheimer's Association diagnostic criteria.ResultsThe overall MCI prevalence was 9.8%, which varied between Hispanic/Latino groups. Older age, high cardiovascular disease (CVD) risk, and elevated depressive symptoms were significant correlates of MCI prevalence. Apolipoprotein E4 (APOE) and APOE2 were not significantly associated with MCI.DiscussionMCI prevalence varied among Hispanic/Latino backgrounds, but not as widely as reported in the previous studies. CVD risk and depressive symptoms were associated with increased MCI, whereas APOE4 was not, suggesting alternative etiologies for MCI among diverse Hispanics/Latinos. Our findings suggest that mitigating CVD risk factors may offer important pathways to understanding and reducing MCI and possibly dementia among diverse Hispanics/Latinos.

上海市闵行区性病门诊本地和外来病人的比较研究

目的分析和比较上海市闵行区性病门诊本地与外来病人的流行病学特征。方法对2001~2004年上海市闵行区3家设有标准化性病门诊的公立医院进行门诊病历的回顾性分析。结果外来人口约占全部性病门诊病人的50%,其中女性病例占18.2%,未婚者占23.8%,均高于本地同类人员的比例;外来病人年龄偏低,多重感染者比例较高;男女外来病人与本地病人的首诊原因和症状排位相同,均以淋病感染为主;外来病人随访率(81.2%)较本地病人低(86.0%)。结论性病门诊本地和外来病人在人口学特征、诊疗行为上存在差异,防制措施应有所不同和侧重。     

东南欧国家旋毛虫病的流行现状

旋毛虫病在东南欧的巴尔干半岛及临近国家的流行现状各不相同,在保加利亚、塞尔维亚和黑山、罗马尼亚及克罗地亚,猪和人的旋毛虫感染率均较高;在波斯尼亚和黑塞哥维那则具有中度的旋毛虫感染率;在匈牙利已有多年未发现人体旋毛虫病,但近2年来已发现了散发的猪旋毛虫病。旋毛虫病在东南欧国家的再度肆虐,提示旋毛虫病能够突破食品安全体系和兽医检疫的薄弱环节,从而可导致地区性、全国性甚至国际性的旋毛虫病扩散。该文对旋毛虫病在东南欧国家的历史、分布、流行现状、感染来源、虫种及再度肆虐的原因等进行了综述。

Epidemiology of acute diarrhea in children living in Sicily

A longitudinal survey (February 1984 - January 1985) on the incidence of acute diarrhea episodes in a sample of 8,164 children (aged 0–12 years) living in southeastern Sicily was carried out by means of weekly telephone interviews with doctors practising in the territory. The incidence rate was 0.479 (0.472–0.485 95% C.I.) per child per year and the frequency of episodes was significantly higher (p < 0.001) in children aged 0–4 years (0.86). Diarrhea was more frequent in industrial areas than in rural ones, and almost half (45.1%) of the total episodes had a mild course. No death from diarrhea occurred and admission to hospital was reported for 8.4% of all cases.Corresponding author.
