This 1-year (September 2000 to August 2001) prospective study investigated the presence of hepatitis A virus (HAV) in the population of Monastir, Tunisia (86 serum samples), in the influents and effluents of two wastewater treatment plants, and in shellfish harvested in the coastal areas of Monastir, Bizerte and Sfax (January 2001 to May 2001). The virus was detected by RT-PCR using primers targeted at the VP3-VP1 region. An epidemic of HAV infection was observed during the winter months, with a peak in January. The presence of the virus was relatively constant in the influents and effluents of the wastewater treatment plants, and the virus was found in shellfish from the Monastir area during the months of January and February. The genotype IA strain was recovered most frequently from human serum and wastewater samples. The observation that the peak of the epidemic was during the winter months suggests that transmission of HAV is related to climatic factors and, presumably, to shellfish consumption. 相似文献

目的了解市动力区7~10岁儿童多动症的发病情况及其有关因素。方法采用分层整群抽样法对1377名儿童进行多动症的流行病学调查,主要以DSM—Ⅲ中的ADD诊断标准为参考综合诊断病例。结果多动症检出率为6.89%(95例/1377);父母为工人、父文化为小学或文盲的,检出率最高,分别为7.34%、7.72%及8.77%;父母大学文化的检出率最低(5.16%和2.83%);母孕期经受负性生活事件及家庭环境不良是多动症发病的危险因素。结论哈市动力区7~10岁多动症检出率较高;与发病有关的因素复杂多样。 相似文献

The effects of regular daily coffee consumption on liver enzymes were studied in a large number of subjects from the general population. In coffee drinkers, liver enzymes (gamma-glutamyl transferase, alkaine-amino transferase, and alkaline phosphatase) and serum bilirubin were lower than in non-coffee-drinking subjects or in those consuming less than 3 cups daily. The hypothesis proposed is that liver enzymes are a target for caffeine contained in coffee. 相似文献

An outbreak of cholera in a refugee camp in Africa 总被引:1,自引:0,他引:1

A total of 541 cases of cholera were observed between May 7 and July 19, 1985 among the 9,929 displaced persons present in a refugee camp in Africa.In spite of malnutrition and other diseases affecting this population, only 12 deaths occurred.Antiepidemic measures consisted of preparation of isolation-wards, treatment of contaminated materials, training of refugees and patient care. Mass prophylaxis, initially considered, was dropped before the end of the epidemic.Corresponding author. 相似文献

Prevalence of hereditary ataxias and spastic paraplegias in Molise,a region of Italy 总被引:8,自引:0,他引:8

Summary An epidemiological survey of hereditary ataxias and paraplegias was conducted in Molise, a region of Italy (335, 211 inhabitants on 1 January 1989). Total prevalence was 7.5 x 10–5 inhabitants (95% confidence limits 4.8–11.1). There were 7 patients with Friedreich's disease, 5 with early onset cerebellar ataxia with retained tendon reflexes, 4 with ataxia-telangiectasia, 9 with hereditary spastic paraplegias (2 autosomal dominant and 7 autosomal recessive cases). There was no patient with autosomal dominant cerebellar ataxia. 相似文献

Validity of a postal questionnaire with regard to the prevalence of myocardial infarction in a general population sample 总被引:1,自引:0,他引:1

In order to evaluate the possibility of finding persons whohave suffered a myocardial infarction (MI) by postal questionnaire,a self-administered questionnaire was sent to a random sampleof 4400 men aged 4564 years, drawn from the general population.The response rate was 95%. 176 men indicated that they had beenhospitalized for MI, out of which 124 cases could be verifiedfrom medical records. Of the remaining men, 33 had evidenceof cardiovascular disease (CVD) in their records but no MI,and 19 men had no evidence of CVD. The sensitivity (estimatedfrom a subsample) was 100% and the specificity 98.7%. The predictivevalue was 100% for a negative response and 70.5% for a positiveresponse. The 33 positive responders whose MI could not be verified butwho had evidence of CVD had characteristics fairly similar tothe responders with verified Mis. However, the 19 positive responderswhose MI could not be verified and who had no evidence of CVDhad characteristics that were dissimilar from the MI group aswell as from the negative responders. The questionnaire thus identified all the MI cases. The needfor validation can be limited to the relatively small groupof positive responders. 相似文献

Summary This study describes sleep behaviour and insomnia in a representative cohort of a Swiss population. Interviews were carried out prospectively from age 20–21 to 27–28 years, starting with 292 males and 299 females. Females usually go to bed earlier and sleep 30 min longer than males. Taking into account length and periodicity of insomnia we can distinguish occasional insomnia (OI), repeated brief insomnia (RBI), and continued insomnia (CI), defined by operational criteria. The prevalence of sleep problems is stable from age 21–28, at 36%–40%. CI (prevalence 8%–10%) and RBI (13%–19%) are both medical problems in terms of treatment by professionals (10%–17%) or self-medication (7%–12%). The majority of insomniacs cope with sleep problems in various other ways. Frequency and patterns of symptoms of insomnia are described.The authors thank P. J. Clayton, M.D., University of Minnesota, Minneapolis, for advice and critical suggestions and for the coining of the terms repeated brief insomnia and continued insomnia.Project supported by grant 3.948.0.85 from the Swiss National Science Foundation.Parts of this article were presented on the occasion of the inauguration ceremony of the Department of Psychiatry of the University of Mainz on April 2 and 3, 1987 相似文献

PurposeNoroviruses are common viral agents in acute diarrhea in all age groups worldwide. Norovirus has been classified into 10 genogroups, GI to GX with over 48 genotypes among them the GII.4 genotype has evolved over time with a clear pattern of periodic variant replacement. Immunity is strain or genotype specific with little or no protection conferred across genogroups. The present study was aimed to determine the epidemiology, prevalent genotypes of norovirus in children below five years of age in the Hyderabad region, India.MethodsThe stool samples and clinical data were collected from 458 children below 5 years of age comprising of cases with acute gastroenteritis (n ?= ?366) and a control group (n ?= ?92) admitted to the pediatric ward. All the samples were tested for Norovirus by ELISA and RT-PCR. Sequencing was done for predominant strains.Results10.3% (n ?= ?38) of cases and 3.2% (n ?= ?3) of the control group were found to be Norovirus positive. Predominant genotypes were GII-82.5% followed by GI-12.5%.ConclusionSequencing and Phylogenetic analyses of 20 GII.4 strains was done. All of the isolates are clustered away from published the GII.4 variants thus suggesting the appearance of a new variant. 相似文献
