Family violence among psychiatric in-patients as measured by the Conflict Tactics Scale (CTS)

The aim of this study was to analyse the frequency and pattern of family (domestic) violence in a group of psychiatric in-patients by using the Conflict Tactics Scale. The study is based on a consecutive series of 55 married or cohabiting psychiatric in-patients treated at Huddinge Hospital, Stockholm, Sweden in 1994. The study shows that males and females use similar types of both violent and non-violent strategies when trying to solve marital conflicts. Depressed patients use both non-violent and violent methods less often than non-depressed patients, while the opposite is true for patients with a personality disorder, and for schizophrenics. Psychosocial stressors appear to be of limited importance in this context, while poor general functioning is associated with destructive ways of trying to solve conflicts between husband and wife. However, there have been no Scandinavian population-based studies to establish the frequency and type of violence used when trying to solve marital conflicts. Thus there is a need for such studies, and the present investigation supports the American experience that the Conflict Tactics Scale is a usable and easily administered instrument for population-based studies.     

The epidemiology and surveillance of blood lead in Taiwan (R.O.C.): A report on the PRESS-BLL project

 To monitor the lead hazards in industries and to investigate the prevalence of elevated blood lead levels (BLLs) in lead-exposed workers, a lead surveillance system (PRESS-BLLs) has been established and operated in Taiwan, Republic of China, since July 1993. A cohort of lead-exposed workers who received a periodic annual health examination at 55 accredited hospital laboratories was constructed. A total of 9807 separate BLL measurements were reported to the system in 1994. The mean BLL was 15.8 μg/dl in male workers and 11.6 μg/dl in female workers. The mean BLL of lead-exposed workers was significantly (P<0.05, z-test) higher than that of the general Taiwanese population (8.6 μg/dl for males and 6.7 μg/dl for females). In addition, the BLLs of 983 (10.0%) workers exceeded the regulatory action level (40 μg/dl for males; 30 μg/dl for females). The workplaces and homes of 57% of the workers with elevated BLLs were thoroughly investigated to determine the sources of lead contamination. These actions identified the causes of elevated BLLs and set up strategies to reduce workers’ lead exposure. The establishment of this occupational lead surveillance system represents a method for monitoring of lead hazards from occupational and environmental settings to prevent lead poisoning. The information acquired from the system can help in the setting up of a priority of prevention and the development of control measures. It is also useful for further monitoring of changes in the BLLs of the lead-exposed-worker cohort. The Health Department of Taiwan can use this information to evaluate the effectiveness of current industrial hygiene practice. Subjects with elevated BLLs have been medically treated and placed on long-term follow-up for sequelae. Received: 2 September 1996/Accepted: 29 November 1996     

Thioether excretion of workers exposed to bitumen fumes

Summary The excretion of thioethers was determined in the urine of workers involved in road paving operations and in the preparation of asphalt mixing in an asphalt plant. An occupationally nonexposed group served as control. From the results it was observed that there was no significant difference in urinary thioether levels between the exposed and nonexposed groups, however, smokers of both exposed groups had significantly higher urinary thioether levels than the nonexposed smoking workers. These results suggested that higher urinary thioether excretion could be only due to a difference in smoking behaviour. There were also significant differences in urinary thioether levels between the exposed smoking and nonsmoking workers. The authors suggest that these workers have a low mutagenic/carcinogenic risk and smoking is responsible for the majority of thioether excretion, as has been found by other investigators.     

护理人员的职业损伤因素及健康维护

作者指出临床一线的护理人员是发生职业损伤的高危群体。产生职业损伤的危险因素包括基础教育和继续教育缺乏职业损伤及其防范知识；影响护理人员身体健康的诸因素，如化疗专用的溶药设备、洁净操作台或相对密闭的溶药环境不健全；乙型肝炎等医院内易感性等疾病增加，被血液、体液等污染的医疗锐器刺伤是护理人员职业感染的主要途径；护理人员工作职业特点对健康不利的影响，护理人员心理压力大。为维护护理人员身心健康，应加入医院感染、职业损伤和健康维护的在校理论教育内容，加强护理人员职业安全教育，采取防范职业损伤的措施，如化疗药物中心配药、使用一次性手套等措施。     

日晒海盐工人机体内高镁反应

报道福建某盐场从事日晒海盐生产人工机体内高镁对心血管系统的影响，通过现场空气、饮水、主良的镁含量测定，并对进入机体途径进行分析，得出空气、卤水接触、饮水为机体镁增高的主要来源。不同对象头发镁含量测定结果显示，以接触卤水、劳动强度大的盐工最高，并随机体内镁含量增高，出现血压偏低、心率减慢、心电图Ｐ－Ｒ间期延长、ＱＲＳ波增宽、Ｔ波高尖等机体高镁反应，与临床高镁血症相似。
