Modest associations between self-reported physical workload and neck trouble: a population-based twin control study.

Objectives: To investigate the relationship between self-reported physical workload and neck trouble (NT) in twins. Additionally, to explore whether the relationship between physical workload and NT is influenced by genetic factors.

Methods: A twin control study was performed within a population-based, cross-sectional questionnaire study using 3,208 monozygotic (MZ) and same-sexed dizygotic (DZ) twins aged 19-70.

[Lung cancer as a consequence of passive smoking recognized as an occupational disease for the first time in Denmark].

The International Agency for Research on Cancer (IARC) has stated that exposure to "secondhand" or "environmental" tobacco smoke is carcinogenic to humans. The first Danish case of adenocarcinoma in the lungs recognized and compensated as an occupational disease in a never-smoking waitress is described.

Intensive education combined with low tech ergonomic intervention does not prevent low back pain in nurses.

Aims: To evaluate the effectiveness of an intensive educational and low-tech ergonomic intervention programme aimed at reducing low back pain (LBP) among home care nurses and nurses' aids.

Methods: In 1999, 345 home care nurses and nurses' aids in four Danish municipalities were studied. Participants in two municipalities constituted the intervention group and participants in the other two served as the control group.

Psychosocial factors at work in relation to low back pain and consequences of low back pain; a systematic, critical review of prospective cohort studies.

Relevant studies of low back pain (LBP) published between 1990 and 2002 were systematically retrieved via electronic databases and checking of reference lists. Forty papers fulfilled the inclusion criteria; 10 were of high quality. A wide variety of instruments had been used for collection of data on work related psychosocial factors, many of which had not undergone any form of validation.

Ambiguous relation between physical workload and low back pain: a twin control study.

Aims: To examine the association between self reported physical workload and low back pain (LBP) in younger twins. To investigate whether genetic factors interact with physical workload in relation to LBP.

Methods: A twin control study was performed within a population based twin register using 1910 complete monozygotic (MZ) and same sexed dizygotic (DZ) twin pairs aged 25-42 and discordant for LBP.

[Increased frequency of traffic accidents among patients with disseminated sclerosis].

Introduction: The influence of medical conditions on the ability to drive safely is a matter of concern to both physicians and society. Obviously, the symptoms in multiple sclerosis (MS) are of relevance when driving a car. Nevertheless this problem has never before been subject to scientific investigations.

[Increased frequency of driving accidents in epilepsy].

Introduction: The influence of medical conditions on the ability to drive safely is a matter of concern to both physicians and society. Satisfactory answers to the many questions are not yet available, because of methodological difficulties, including the inability to collect sufficiently large and representative samples of drivers with specific diseases, and to acquire reliable accident data. For epilepsy, the conclusions of scientific reports vary from "there is little to worry about" to an increased relative risk of 1.
