A cross-sectional postal survey of 29,424 people aged 12-41 years obtained from a population-generated panel of twin individuals. ⋯ There is a definite link between smoking and low back pain that increases with the duration and frequency of the low back pain problem, but this link is unlikely to be causal.

Case Reports
[Severe hepatocellular damage after administration of paracetamol and chlorzoxazone in therapeutic dosage].
A 64 year old patient developed severe hepatocellular damage with jaundice and coagulopathy during ingestion of a combination of paracetamol and chlorzoxazone in therapeutic dosage. The risk factors for the development of liver cell necrosis following ingestion of paracetamol in therapeutic dosage are discussed. In particular in patients with risk factors (e.g. alcoholics and patients with heart failure) paracetamol-induced liver failure has to be considered in the presence of high transaminases, even when paracetamol was ingested in therapeutic dosage. Chlorzoxazone itself rarely can induce an idiosyncratic hepatocellular damage.

Randomized Controlled Trial Comparative Study Clinical Trial
Components of initial and residual disability after back injury in nurses.
A pre- versus postintervention with concurrent control group design was used to investigate the effect of a workplace-based early intervention program on perception of disability in nurses with low back injury. ⋯ Although overall perception of disability decreased 6 months after injury, particularly in study nurses, disability in job-related activities persisted. Residual disability after back injury should be addressed in workplace-based prevention programs.

In a national cross-sectional study, the prevalence of neck/shoulder and low-back disorders and their relationship to work tasks and perceived psychosocial job stress was studied among forestry employees. The data were collected by occupational health service staff using Karasek's demand/control questionnaire for the psychosocial measures and the Standardized Nordic questionnaire for the analysis of musculoskeletal disorders. Based on data about past and present work tasks, the study population was classified into three groups: 645 manual workers, 66 machine operators and 124 administrative workers. ⋯ In conclusion, musculoskeletal disorders were associated with both physical and psychosocial work factors. The modest strength of the associations between each individual independent variable and the outcome measure shows, however, that a substantial reduction in the prevalence of musculoskeletal disorders may be difficult to achieve. Nevertheless, the study clearly suggests that in the forestry industry attention should be paid to psychosocial work factors in future organizational changes and preventive programmes.

Introduction. At the present time, there is no reliable method or drug for effective relief of the severe pain caused by the amyloldotic polyneuropathy (AP). Objective. ⋯ The patient had the IT treatment for 867 days, of which 777 days (> 90%) were spent at home. Conclusion. Long-term IT administration of opioid and bupivacaine provided satisfactory long-term pain relief in a patient with refractory pain due to AP.
