Despite markedly different national suicide rates, the prevalence of self-harm in Scotland is similar to that in England with girls at least three times more likely to report self-harm than boys. The findings suggest a role for emotional literacy programmes in schools and highlight the importance of promoting positive mental health among adolescents.

A consecutive sample of 97,537 miners seeking compensation for Hand-Arm Vibration Syndrome were examined in a medical assessment process which included documentation of age, hand dominance, Dupuytren's disease, years of vibration exposure, history of diabetes, smoking habits and units of alcohol consumption per week. The prime determinant of prevalence of Dupuytren's disease was age, and all other factors investigated were corrected for age. There was no statistically significant correlation between years of exposure to vibration and the prevalence of Dupuytren's disease. There was a statistically significant association with smoking, alcohol consumption and diabetes mellitus, with the heaviest smokers having an odds ratio (OR) of 1.31 (95% CI, 1.17, 1.47), the heaviest drinkers (in excess of 22 units a week) having an OR of 1.59 (95% CI, 1.47, 1.72) and diabetes mellitus patients having an increase in the odds of having Dupuytren's disease of 1.52 (95% CI 1.30, 1.77).

In the United Kingdom the diagnosis of Hand-arm Vibration Syndrome varies depending on the purpose of that diagnosis. The criteria differ in three situations. More than 100,000 miners and ex-miners with claims for HAVS have been examined using a Medical Assessment Process which included the use of standardised tests. This contract is unique but it has had significant effects on the two other processes. The Industrial Injuries Disablement Benefit Scheme provides a benefit that can be paid to an employed earner because of an accident or Prescribed Disease. New recommendations have been published to remove the anomalies in the present format for assessing HAVS. If implemented the new scheme will recognise the Stockholm Workshop Scales and workers with neurological problems will also be compensated. The Health and Safety Executive will issue new guidance in the near future on the hazards of hand-arm vibration. Health surveillance in the workplace will be fundamental and the HSE propose a tiered approach with levels 1 to 5. Specialist occupational nurses and doctors with training in the diagnosis and assessment of HAVS will be needed for levels 3 and 4. Only at this level may a diagnosis of HAVS be made. The Medical Assessment Process has demonstrated that it is possible to examine a large number of claimants in a standardised manner. The IIAC and HSE recommendations contain very important improvements on the existing positions in the UK and it must be hoped that they will be implemented in the near future.

In its present format, the CPT should not be used for evaluating the vascular component of HAVS.

Twenty six thousand eight hundred and forty-two miners seeking compensation were clinically assessed for vascular and neurosensory impairment arising from exposure to occupational hand-arm vibration (Hand-Arm Vibration Syndrome). They were also assessed clinically for Carpal Tunnel Syndrome which, if present, would result in additional compensation. Fifteen per cent were assessed as having both HAVS and CTS. Thirty-eight per cent of claimants had nocturnal wakening, 1.3% wasting of abductor pollicis brevis, 15% had a positive Tinel's test and 20% had a positive Phalen's test. The 15% prevalence reported is lower than the rates cited previously in several small population studies of workers exposed to vibration. This paper reports the results of the assessment process and discusses the difficulty of discriminating Carpal Tunnel Syndrome from diffuse neurosensory impairment arising from HAVS.

Different end organs and nerve fibres should be tested when making an assessment of damage in the sensorineural component of HAVS. The correlations demonstrated for the VTT and TA suggest that they are of value in assessing these claimants and would be for other vibration exposed workers.

The present study examined whether social evaluation could heighten individuals' physiological responses to the CO(2) stress test, and the hypothalamic-pituitary-adrenal (HPA) response in particular. Twenty-five healthy volunteers undertook the CO(2) test under three conditions: (i) standard CO(2) protocol, (ii) standard CO(2) protocol conducted in front of a full-length mirror (mirror) and (iii) standard CO(2) protocol conducted in front of a video camera deemed to be transmitting live images of the procedure to investigators evaluating participant performance (video). Despite counterbalancing for task order, there were significant differences in anger and depression among the conditions. Repeated measures analysis of variances (ANOVAs), controlling for these mood indices, revealed that salivary cortisol, heart rate and systolic blood pressure responses to the CO(2) test were not affected by social evaluation (i.e. mirror or video). Although the data provide no evidence that endocrine and cardiovascular responses to the CO(2) test are affected by social evaluation, the potency of the social evaluation manipulation in this study is in question. Thus, further research is warranted which includes evidence of, or instructions suggesting negative social evaluation.
