对一宗入境二级放射货包的监测结果分析

汕头卫生检疫局空港处对汕头航空口岸—宗入境二级货包的监测过程及对有关运输工作人员作了放射知识问卷调查。从中发现。运输单位货物存放设施落后。有关工作人员放射卫生知识欠缺，对放射污染可能造成的危害缺乏正确的认识。为此，笔者提出了自己的看法，以期对放射监测工作的进一步完善提供参考。     

一起阴囊皮炎爆发流行的调查与实验研究

本文报道了一起183例农民阴囊皮炎的爆发流行,发病率高达56.63%,不同的年龄、职业与发病率无显著差别,八月份为发病高峰。同时患有口角炎、舌炎并发症者占45.65%,取14例典型患者的阴囊鳞屑作真菌镜检,检出霉菌1例。85例患者经采用核黄素10mg,加复合维生素B10mg,每日两次连服七天进行试治,治愈率为96.47%(82/85),将19例患者与20例健康者对照,作4h尿中核黄素负荷试验比较,结果两者在统计学上具有显著性差别(u=2.11,P≤0.05)。经膳食营养调查,发现6~10月份核黄素供给不足47%。由此证明,发病与核黄素缺乏有关。     

Therapeutic traditions in type 2 diabetes — are they changing?

The utilisation of antidiabetic drugs reflects both the prevalence of diabetes and the different therapeutic traditions of physicians. A questionnaire survey to study attitudes to the use of oral antidiabetic drugs amongst physicians and possible changes in treatment habits was carried out in a representative sample of Finnish physicians (n=454) in 1992 and the results were compared with those of a similar survey carried out in 1985, and with drug utilisation statistics.The mean fasting blood glucose level at which a physician would start pharmacological treatment was 8.7 mmol·l^–1, which was significantly lower than in the 1985 survey. The responses to various case histories suggested a more active approach to pharmacological treatment compared to the 1985 survey. Insulin treatment especially seems to have gained in popularity. This change in attitude was paralled by an increase in the consumption of antidiabetic drugs in Finland during the observation period. The increase in use of oral drugs was steeper in Finland than in Norway and Sweden.Whether this active approach will improve the metabolic control and prognosis of patients with Type 2 diabetes, remains to be demonstrated.     

A survey of the use of special food products by diabetics

A food frequency of consumption questionnaire was completed by 137 diabetic outpatients attending the University of Wales Hospital in Cardiff, to provide information about the use of special dietary products.
Seventy-four per cent of the diabetics used special dietary products, the most popular of which were artificial sweeteners (45%) and preserves (47%), followed by squash (34%), sweets (31%) and chocolate (31%). Twenty per cent of diabetics consumed biscuits and tinned fruit. Cake and other products (e.g. jelly), were used by less than 10% of the respondents. Over half of all the diabetics consumed one or more products on a daily basis. The use of special products bore no significant relationship to the sex of the respondents, nor to the duration of the diabetes. However, a significantly higher proportion of the Insulin Dependent Diabetics (IDDM) group used dietary products compared with the Non-Insulin Dependent Diabetics (NIDDM) group. This can be explained largely by the differences in age between the diabetics; the under-18-year-old age group (who were all IDDM respondents) were the greatest users of sweets, chocolate and squash.
Forty-three per cent of diabetics who did not use special food products cited at least one reason for non-use. The reasons included dietetic advice (NIDDM respondents only), high cost, poor palatability, lack of availability and unsuitability for other members of the family.     

中国维和部队士兵性观念和性心理的调查研究

目的:掌握中国维和部队士兵性观念和性心理状况,力图加以正确引导和心理干预。方法:在维和任务中期,采用自编问卷,对314名中国驻利比里亚维和士兵进行性观念和性心理方面的调查。结果:超过90%的士兵性知识来源于自学,部分士兵性知识相对缺乏,通过集训的学习,仍有77%的战士对“艾滋病”有恐惧感。与未婚士兵相比,已婚士兵显示出更成熟的性心理(P<0.05);而性观念上差异没有显著性(P>0.05)。结论:针对不同群体进行有效的心理干预和心理疏导,能让士兵理智地对待自己的性欲和愿望,把性能量升华为内在的工作动力,创造性地开展维和工作。     

Methods for analysis of a food frequency questionnaire

Fifty-five students and staff at Robert Gordon's Institute of Technology completed a food frequency questionnaire and then weighed their food for one week. Several methods of calculating nutrient intakes from the questionnaire are compared to results from the weighed inventory. Intakes of energy and several nutrients calculated using estimated typical portion weights were less than those derived from the weighed inventory. Food groups contributing to the apparent under-estimation have been identified. A further method of calculation involved derivation of a factor for each food group such that the frequency estimated from the questionnaire multiplied by the factor equalled the average weight of the foods in that group that had been eaten. Using these factors instead of the typical portion weights resulted in closer agreement to the weighed inventory method, but the difference ranged from positive for some groups to negative for others. Use of separate factors for each group of subjects reduced the range of differences to the weighed inventory method.     

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     

THE POINT PREVALENCE OF WOUNDS IN A TEACHING HOSPITAL

Background : Wounds are a common problem, particularly in the elderly population. The scale of wound problems in hospital is largely unknown because wounds are widely dispersed. The present study examined the point prevalence of hospital wounds and undertook a pressure ulcer risk assessment of all patients on one day. Methods : All 360 inpatients were surveyed and thoroughly examined. A risk scale for pressure sore development, the Norton score, was applied. When wounds were found, information was collected to determine their aetiology. Results : Forty leg ulcers, 40 pressure sores, 85 surgical wounds and seven other types of wounds were found. Most leg ulcer and pressure sore cases were admitted for other reasons. The Norton score did not predict all cases of pressure ulceration. A total of 52% of wounds did not qualify for additional funding under current funding criteria. Conclusion : The prevalence of non-surgical wounds in Heidelberg Repatriation Hospital was easily underestimated. Wound care management can be optimized by staff education and protocol design, early identification of troublesome wounds and of at-risk patients, and a cross-sectional approach that incorporates wound-management teams.
