Respiratory symptoms associated with the use of azodicarbonamide foaming agent in a plastics injection molding facility

Respiratory health variables were studied cross-sectionally in 227 employees of a plastics molding facility where numerous complaints had been apparently associated with the use of azodicarbonamide foaming agent in injection molding. Pre- and postshift respiratory status measures and azodicarbonamide concentrations were also obtained for 17 employees. Cross-sectional pulmonary function differences by injection molding status were not observed. Modest decrements in pulmonary function measures were observed between start and end of shift but with no dose-effect relationship. A strong association was observed for injection molding workers for eye/nose/throat irritation, cough, and wheezing. Additionally, wheezing, chest tightness, and symptoms of chronic bronchitis were strongly associated with work in injection molding during periods in which azodicarbonamide was in use. These results suggest respiratory symptom causation by some combination of azodicarbonamide itself, reaction products of azodicarbonamide formed during injection molding, or other unidentified agents uniquely associated with the process of injection molding with azodicarbonamide foaming agent.     

Evaluating podiatry services: Testing a treatment specific measure of health status

This study reports on the preliminary testing of a new measure designed for use alongside EQ-5D in evaluating outcomes in podiatry: the Podiatry Health Questionnaire (PHQ). Individuals aged 18 years or more, receiving podiatry services in clinic or domicilliary locations across four NHS Trusts in Yorkshire and Humberside UK took part in a questionnaire survey. Respondents reported high levels of problems on all six PHQ dimensions. Correlations suggested that the PHQ and EQ-5D were measuring distinct constructs. The levels on each dimension were well defined in terms of self-rated morbidity on the PHQ visual analogue scale (PHQ_vas) and the EQ-5D_vas, although PHQ_vas appeared to be slightly more sensitive to changes in health on the dimensions. There was a strong relationship between clinicians' Podiatry Clinical Score rating and reported symptoms for four out of six PHQ dimensions and PHQ_vas. The PHQ was able to distinguish respondents in terms of their self-reported morbidity in EQ-5D and in terms of their morbidity as assessed by clinicians. It is suggested that the respondent completed PHQ appears to be a useful new measure for assessing foot-related health. However, further investigation of the psychometric properties of the measure is required.     

Self-selection of enrollers at the creation of a managed care organization

Factors affecting choice between a managed care organization(MCO) and a fee-for-service insurance plan were examined whenthe University of Geneva health insurance plan was transformedinto an MCO, in October 1992. A case-control study using a mailedquestionnaire (response rate 84%) was conducted to compare formermembers who joined the MCO (joiners, n=421) to former memberswho opted out in order to keep fee-for-service coverage (non-joiners,n=222). Non-joiners were more likely to be women (odds ratio(OR) from multivariate model was 1.15, p=0.50), to be born inSwitzerland (OR=2.04, p<0.01), to have an annual income >75,000Swiss francs (OR=2.00, p<0.01), to have a personal physician(OR=1.96, p<0.01) and to have consulted a specialist (OR=1.69,p=0.02) or used unconventional medicine (OR=4.59, p<0.01)in the past year. During the previous year, non-joiners hadmore health care visits than joiners (14.6 versus 9.1, p=0.01).Non-joiners reported better mental health and fewer complainedof persistent fatigue (OR=2.18, p=0.03). The choice of healthplan was strongly influenced by socio-demographic characteristics,past patterns of health services utilization and health status.The self-selection process was paradoxical: MCO joiners hadused fewer health care visits than non-joiners, but their self-reportedhealth status was worse. The differences we have observed betweenself-selected populations have important implications for thefinancial performance of competing health care delivery systems.     

2001～2005年安徽省急性血吸虫病疫情分析

目的了解安徽省近年来急性血吸虫病发生和流行规律。方法收集全省2001～2005年急性血吸虫病个案资料,建立数据库,应用VisualFoxpro6.0和Excel2003软件进行分析。结果2001～2005年全省共发生1033例急性血吸虫病病例、19起成批急性血吸虫感染。男性病例是女性的5.4倍,男性病例的主要感染方式为游泳戏水和捕鱼捞虾,女性病例的主要感染方式为游泳戏水、洗刷生活用品和农业生产;所发生病例中学生和农民占比例较高,学生以游泳戏水为主要感染方式,农民以捕鱼捞虾、农业生产为主要感染方式;在湖沼地区感染的病例数稍多于内陆地区,湖沼地区以江滩为主要感染环境,内陆地区以沟渠和河流为主要感染环境;病例分布于14个未控县和9个出现疫情回升的传播控制县和1个传播阻断县;6～8月为接触疫水感染高峰;7～9月为发病高峰;潜伏期平均约40.81±14.28d,最短11d,最长97d,大多数病例在30d以后发病;19起成批急性血吸虫感染均发生于2001～2003年,并多集中于8月份,共有157人,主要是学生、民工和农民,感染方式主要为游泳戏水和捕鱼捞虾。结论安徽省为全国急性血吸虫病流行较重的地区,但成批急性血吸虫感染得到了有效的控制。     

社交焦虑障碍患者父母的人格特征和心理健康状况调查

目的探索社交焦虑障碍(SAD)患者父母的人格特征和心理健康状况。方法设研究组(SAD患者的父母)和对照组。入组时按要求进行艾森克人格问卷(EPQ)和症状自评量表(SCL-90)评定。结果SAD患者的父母在EPQ量表测验中的内外向因子标准分低于对照组;SAD患者的父母SCL-90各项因子除强迫和敌对因子,标准分低于对照组。结论SAD患者的父母的人格特征倾向内向,易安静、内省、离群、不喜欢接触人;SAD患者的父母更容易表现出躯体化症状、人际交往的困惑、抑郁、焦虑、恐怖和偏执。     

Childhood convulsive status epilepticus: epidemiology, management and outcome

Convulsive status epilepticus (CSE) in childhood is a medical emergency and its aetiology and outcome mean that it should be studied separately from adult CSE. The incidence in developed countries is between 17 and 23/100,000 with a higher incidence in younger children. Febrile CSE is the commonest single group with a good prognosis in sharp distinction to CSE related to central nervous system infections which have a high mortality. The aim of treatment is to intervene at 5 min and studies indicate that intravenous (i.v.) lorazepam may be a better first-line treatment than rectal diazepam and i.v. phenytoin a better second-line treatment than rectal paraldehyde. An epidemiological study strongly supports the development of prehospital treatment with buccal midazolam becoming a widely used but unlicensed option in the community. More than two doses of benzodiazepines increase the rate of respiratory depression without obvious benefit. The 1 year recurrence rate is 17% and the hospital mortality is about 3%.
