Acute health effects of the Sea Empress oil spill.
(9/2094)
STUDY OBJECTIVE: To investigate whether residents in the vicinity of the Sea Empress tanker spill suffered an increase in self reported physical and psychological symptoms, which might be attributable to exposure to crude oil. DESIGN: Retrospective cohort study; postal questionnaire including demographic details, a symptom checklist, beliefs about health effects of oil and the Hospital Anxiety and Depression and SF-36 mental health scales. SETTING: Populations living in four coastal towns on the exposed south Pembrokeshire coast and two control towns on the unexposed north coast. PATIENTS: 539 exposed and 550 unexposed people sampled at random from the family health services authority age-sex register who completed questionnaires. MAIN RESULTS: Adjusted odds ratios for self reported physical symptoms; scores on the Hospital Anxiety and Depression and SF-36 mental health scales, in 1089 people who responded out of a possible 1585 (69%). CONCLUSIONS: Living in areas exposed to the crude oil spillage was significantly associated with higher anxiety and depression scores, worse mental health; and self reported headache (odds ratio = 2.35, 95% CI 1.56, 3.55), sore eyes (odds ratio = 1.96, 95% CI 1.06, 3.62), and sore throat (odds ratio = 1.70, 95% CI 1.12, 2.60) after adjusting for age, sex, smoking status, anxiety, and the belief that oil had affected health. People living in exposed areas reported higher rates of physical and psychological symptoms than control areas. Symptoms significantly associated with exposure after adjustment for anxiety and health beliefs were those expected from the known toxicological effect of oil, suggesting a direct health effect on the exposed population.

Computer-based teaching of pathology at the Zagreb University School of Medicine.
(10/2094)
AIM: To review the experience gained in transferring USA computer-based teaching system of medical school pathology to Croatia. METHODS: Computer-based teaching program of pathology developed at the University of Kansas School of Medicine, Kansas City, Kansas, USA, was transferred to the University of Zagreb School of Medicine, Zagreb, Croatia. The experimental group of 49 students was enrolled into this computer-based program. Their performance was compared with that of 195 classmates enrolled in the standard course. Objective (performance on the examinations) and subjective data (students' interviews and written evaluations of the course) were analyzed. RESULTS: The computer program was operational 5 months from the inception of the transfer. It was well received by the students, even though many initially complained that it required more effort and a continuous commitment. The major problems concerned scheduling, reflecting various requirements i mposed on students by other departments teaching in parallel with the Pathology course. Objective data gathered so far indicate that the students enrolled in the computer-based program took the first midterm examination at a significantly higher rate than the rest of the class (p<0.001), and passed the examination with significantly better grades (p<0.001). CONCLUSION: Computer-based teaching programs can be readily transferred to other countries. Full implementation of the program, however, may require significant changes in the existing curriculum in the medical school to which such a program has been transferred or considerable modifications in the program adopted for transfer. It appears that the students enrolled in the computer-based program perform better than students in the standard pathology course. (+info)
Building peace from scratch: some theoretical and technological aspects.
(11/2094)
A peace-building process is based on activity, acceptance, understanding of political reality, communication, and empowerment. Acceptance means accepting everybody as he or she is and let each know it. This is at the heart of peace work, it is the prerequisite for effective communication, and includes accepting other even in cases of severe disagreement. Peace work requires both an understanding of political reality and the expression of one's own political opinion. Acceptance and the expression of political opinion are not at variance but complementary. Combining acceptance and understanding of the political context provides hope for real communication in which messages are both sent and received, with appreciation and interest. Empowerment implies overcoming of the feeling of powerlessness, often present in conflict by all sides and in all social groups. It includes recovery of self-respect and respect for others. Education and economic independence are important facets of the empowerment concept. Essential principles of peace-building process are responsibility, solidarity, cooperation, and nonviolence. Responsibility encompasses caring for human rights, the suffering of others, and for consequences of our own intended and unintended actions. Solidarity allows learning through listening and understanding. Even with the best intentions on both sides, cooperation may be difficult and painful. Nonviolence is a way of life. (+info)
Patients' attitude toward consultations by a physician without a white coat in Japan.
(12/2094)
OBJECT: To know how Japanese patients perceive their physicians without a white coat during consultations. SUBJECTS AND METHODS: The patients who visited a university clinic were divided into two groups: those seen by a physician in a white coat (the white-coat group) and those seen by a physician in private clothes (the private-clothes group). Questionnaires were distributed to the patients, which asked the tension and satisfaction of consultations as well as their preference for physician's attire. The answers of the white-coat group were compared with those of the private-clothes group. RESULTS: The percentage of new patients who felt tense during consultations was greater in the white-coat group (42%) than in the private-clothes group (33%). Seventy-one percent of the patients in the white-coat group preferred physicians in a white coat whereas only 39% preferred so in the private-clothes group (p<0.0001). However, the degree of patients' satisfaction for the consultation showed no statistical difference between the groups. Sixty-nine percent of the patients older than or equal to 70 years preferred a white coat while 52 percent of the patients younger than 70 years preferred so (p=0.002). CONCLUSION: Physician's white coats did not influence the satisfaction with the consultations for most Japanese patients in a university clinic, although elderly patients as well as those seen by a physician in a white coat tended to prefer the white coat to the private clothes. Furthermore, practice without a white coat might reduce patients' tension during their first consultation. (+info)
Transmitting genetic risk information in families: attitudes about disclosing the identity of relatives.
(13/2094)
Attitudes about disclosing the identities of family members to a physician to ensure diffusion of genetic risk information within affected families were examined in a questionnaire study of Danish patients with alpha1-antitrypsin deficiency (A1AD), their relatives, and a control group of Danish citizens. The questionnaires were returned by 1,761 (82%) of 2,146 recipients; 1,609 (75%) agreed to participate and completed the questionnaire. Only 2.8% objected to disclosing the identity of children, 9.1% objected to disclosing the identity of parents, and 6.7% objected to disclosing the identity of siblings. When genetic tests are offered to a sister, 75.4% of screened individuals with severe A1AD (phenotype "piZ") and 66.8% of piZ probands thought that the physician should say who is ill. Important reasons for informing a sister at risk were, for 58%, the opportunity to prevent disease and, for 41% of piZ-probands, the opportunity to maintain openness in the family and to avoid uncertainty. Stepwise logistic regression of background variables showed that relatives were those for whom most respondents approved the disclosure of the parents' and siblings' identities to enable the physician to examine them for the presence of A1AD. Women were less prone to disclose the identity of siblings. The results indicate that the genetic counselor should inquire about relatives' identities, to ensure that they are properly informed about the known risk of severe genetic disorder, such as A1AD, for which disability can be prevented by a change of lifestyle or by careful management. Disease prevention is essential, but openness and avoidance of uncertainty in affected families are also important. Our findings imply that fully informing all relatives about the disorder and about who is actually ill should be the principal rule. (+info)
Distribution of rest days in 12 hour shift systems: impacts on health, wellbeing, and on shift alertness.
(14/2094)
OBJECTIVES: To investigate of the effects of distribution of rest days in 12 hour shift systems. Although several studies have examined the effects of compressing work schedules by comparing 8 and 12 hour shift systems, there is little published research examining the various forms of 12 hour shift system. METHODS: An abridged version of the standard shiftwork index which included retrospective alertness ratings was completed by a large sample of industrial shiftworkers. The respondents worked 12 hour shift systems that either did or did not incorporate breaks of > 24 hours between the blocks of day and night shifts. For the purposes of the analysis, each of these two groups were further subdivided into those who started their morning shift at 0600 and those who started at 0700. RESULTS: Systems which incorporated rest days between the day and night shifts were associated with slightly higher levels of on shift alertness, slightly lower levels of chronic fatigue, along with longer sleep durations when working night shifts and between rest days. Early changeovers were associated with shorter night sleeps between successive day shifts, but longer and less disturbed day sleeps between night shifts. These effects of changeover time were broadly in agreement with previous research findings. CONCLUSIONS: The distribution of rest days in 12 hour shift systems had only limited effects on the outcome measures, although the few modest differences that were found favoured systems which incorporated rest days between the day and night shifts. It is conceded that the design of the study may have obscured some subtle differences between the shift systems. Nevertheless, it is concluded that the impact of distribution of rest days seems to be minor relative to previously found effects of other features of shift systems--for example, shift duration.

Production and evaluation of guidelines for the management of inflammatory bowel disease: the Leicester experience.
(15/2094)
Consensus guidelines for the management of patients with inflammatory bowel disease were produced by gastroenterologists, gastrointestinal surgeons and a cross-section of general practitioners (GPs) from Leicestershire in order to develop a seamless pattern of care with a common approach to diagnosis and treatment. It was hoped that the guidelines would encourage a movement towards care in the community for many patients with stable disease and so speed up new consultation rates. The study then assessed the impact of these guidelines on the referral letters of GPs to hospital consultants, the prediction of disease and adherence to them on re-referring patients after discharge. The guidelines were distributed to all 487 GPs in the Leicester Health Authority area and the gastroenterology teams within the hospitals. The value of the guidelines was assessed by an audit of referral letters, the length of time from referral letter to out-patient appointment, both before and after the launch of the guidelines, adherence to the guidelines on re-referral, and monitoring the outcome of the discharged patients. Whilst the guidelines may have helped GPs to manage stable patients in the community, the content of referral letters and the diagnostic abilities of GPs were not seen to improve since the launch of the guidelines. However, only 5% of stable patients who were discharged from one clinic were re-referred for inflammatory bowel disease. (+info)
Workers' right-to-know legislation: does it work?
(16/2094)
Workers' right-to-know (WRTK) laws and regulations were established to empower workers to protect their health by providing them with information about the hazards to which they are exposed while at work. The present study was conducted to examine the implementation of WRTK regulations in Israel. We interviewed 552 workers and 33 safety officers from a random sample employed at 50 industrial plants. The workers' questionnaire included items on awareness and self-management of workplace hazards, and the safety officers answered questions about job experience and hazards communications to workers. In 36% of cases workers and their safety officers disagreed about the existence of hazards in the workplace (p < 0.001). Most (78%) of the workers' knowledge about work hazards was based on informal sources, i.e., not those stipulated by the regulations. There were also discrepancies between worker and safety officer reports regarding the provision of safety training upon employment (p < 0.001), recent instructions about special risks and distribution of relevant printed material. We found that more than 5% of workers were unable to read the language in which the hazards material was written and 22% had levels of education below that required to comprehend the technical terms used. There are serious problems in the implementation of WRTK regulations in Israel. We recommend that employers be made aware of the importance of these laws and of their proactive duty to comply with them and that the material distributed to workers be written in simpler terms and/or explained orally in a language they understand. These findings have important implications for all countries with similar legislation and should form the basis for further and more comprehensive studies world-wide. (+info)
