RESUMO
AIMS: To assess the contribution of epilepsy and diabetes to occupational injury. METHODS: The Clinical Practice Research Datalink logs primary care data for 6% of the British population, coding all consultations and treatments. Using this, we conducted a population-based case-control study, identifying patients aged 16-64 years, who had consulted over two decades for workplace injury, plus matched controls. By conditional logistic regression, we assessed risks for diabetes and epilepsy overall, several diabetic complications and indices of poor control, occurrence of status epilepticus and treatment with hypoglycaemic and anti-epileptic agents. RESULTS: We identified 1348 injury cases and 6652 matched controls. A total of 160 subjects (2%) had previous epilepsy, including 29 injury cases, whereas 199 (2.5%) had diabetes, including 77 with eye involvement and 52 with a record of poor control. Odds ratios (ORs) for occupational injury were close to unity, both in those with epilepsy (1.07) and diabetes (0.98) and in those prescribed anti-epileptic or hypoglycaemic treatments in the previous year (0.87-1.16). We found no evidence of any injury arising directly from a seizure and no one had consulted about their epilepsy within 100 days before their injury consultation. Two cases and six controls had suffered status epilepticus (OR versus never had epilepsy 1.61). Risks were somewhat higher for certain diabetic complications (OR 1.44), although lower among those with eye involvement (OR 0.70) or poor diabetic control (OR 0.50). No associations were statistically significant. CONCLUSIONS: No evidence was found that diabetes or epilepsy are important contributors to workplace injury in Britain.

BACKGROUND: It is unclear whether and to what extent intensive case management is more effective than standard occupational health services in reducing sickness absence in the health care sector. AIMS: To evaluate a new return to work service at an English hospital trust. METHODS: The new service entailed intensive case management for staff who had been absent sick for longer than 4 weeks, aiming to restore function through a goal-directed and enabling approach based on a bio-psycho-social model. Assessment of the intervention was by controlled before and after comparison with a neighbouring hospital trust at which there were no major changes in the management of sickness absence. Data on outcome measures were abstracted from electronic databases held by the two trusts. RESULTS: At the intervention trust, the proportion of 4-week absences that continued beyond 8 weeks fell from 51.7% in 2008 to 49.1% in 2009 and 45.9% in 2010. The reduction from 2008 to 2010 contrasted with an increase at the control trust from 51.2% to 56.1%-a difference in change of 10.7% (95% CI 1.5-20.0%). There was also a differential improvement in mean days of absence beyond 4 weeks, but this was not statistically significant (1.6 days per absence; 95% CI -7.2 to 10.3 days). CONCLUSIONS: Our findings suggest that the intervention was effective, and calculations based on an annual running cost of £57 000 suggest that it was also cost-effective. A similar intervention should now be evaluated at a larger number of hospital trusts.

BACKGROUND: Professional musicians have high rates of musculoskeletal pain, but few studies have analysed risks by work activities or the psychosocial work environment. AIMS: To assess the prevalence and impact of musculoskeletal pain, and its relation to playing conditions, mental health and performance anxiety, in musicians from leading British symphony orchestras. METHODS: Musicians from six professional orchestras completed a questionnaire concerning their orchestral duties and physical activities at work, mental health (somatizing tendency, mood, demand, support and control at work, performance anxiety) and regional pain in the past 4 weeks and past 12 months. Prevalence rates were estimated by anatomical site and associations with risk factors assessed by logistic regression. RESULTS: Responses were received from 243 musicians (51% of those approached), among whom 210 (86%) reported regional pain in the past 12 months, mainly affecting the neck, low back and shoulders. Risks tended to be higher in women, in those with low mood, and especially in those with high somatizing scores. Only weak associations were found with psychosocial work stressors and performance anxiety. However, risks differed markedly by instrument category. Relative to string players, the odds of wrist/hand pain were raised 2.9-fold in wind players, but 60% lower in brass players, while the odds of elbow pain were 50% lower among wind and brass players. CONCLUSIONS: Musculoskeletal pain is common in elite professional musicians. A major personal risk factor is somatizing tendency, but performance anxiety has less impact. Risks differ substantially by instrument played, offering pointers towards prevention.

BACKGROUND: Since the early 1990s, rates of incapacity benefit (IB) in Britain for musculoskeletal complaints have declined, and they have been overtaken by mental and behavioural disorders as the main reason for award of IB. AIMS: To explore reasons for this change. METHODS: Using data supplied by the Department for Work and Pensions, we analysed trends in the ratio of new IB awards for mental and behavioural disorders to those for musculoskeletal disorders during 1997-2007 by Government region. RESULTS: In Great Britain overall, the above ratio more than doubled over the study period, as a consequence of falling numbers of new awards for musculoskeletal disorders. The extent to which the ratio increased was smallest in London (50%) and South-East England (56%), and was progressively larger in more northerly regions (>150% in North-East England and Scotland). CONCLUSIONS: The differences in trends between regions seem too large to be explained by differential changes in working conditions, patterns of employment or the rigour with which claims were assessed. An alternative explanation could be that the main driver for the trends has been culturally determined changes in health beliefs and expectations, and that these cultural changes began in London and the South-East, only later spreading to other parts of Britain.

BACKGROUND: An unusual inflammation of the pinna has been reported to occur in some sheep farmers at the time of lambing. AIMS: To explore the prevalence of this disorder and its possible causal associations. METHODS: While on attachment to sheep farms during lambing, veterinary students used a standardized questionnaire to interview a sample of farmers about their work and about symptoms of skin inflammation in their hands, face and ears. RESULTS: Interviews were completed by 76 (67%) of the farmers approached. Among 74 farmers who had carried out lambing, 3 (4%, 95% CI 1-11%) had experienced temporally related ear symptoms, all on multiple occasions. No farmers with ear symptoms had ever been involved in calving or farrowing, and no ear symptoms were reported in relation to shearing or dipping sheep. There was also an excess of hand symptoms related to lambing outdoors (24% of those who had done such work) and indoors (also 24%) compared with other farming activities. CONCLUSIONS: Our findings suggest that temporally related ear inflammation occurs in at least 1% of farmers who carry out lambing but not in association with the other farming activities investigated. Lambing appears to be associated also with hand inflammation, but the pathology may differ from that in the pinna.

BACKGROUND: National initiatives to prevent and/or manage sickness absence require a database from which trends can be monitored. AIMS: To evaluate the information provided by surveillance schemes and publicly available data sets on sickness absence nationally from musculoskeletal disorders (MSDs). METHODS: A grey literature search was undertaken using the search engine Google, supplemented by leads from consultees from academia, industry, employers, lay interest groups and government. We abstracted data on the outcomes and populations covered and made quantitative estimates of MSD-related sickness absence, overall and, where distinguishable, by subdiagnosis. The coverage and limitations of each source were evaluated. RESULTS: Sources included the Labour Force Survey (LFS) and its Self-reported Work-related Illness survey module, the THOR-GP surveillance scheme, surveys by national and local government, surveys by employers' organizations and a database of benefit statistics. Each highlighted MSDs as a leading cause of sickness absence. Data limitations varied by source, but typically included lack of diagnostic detail and restriction of focus to selected subgroups (e.g. work-ascribed or benefit-awarded cases, specific employment sectors). Additionally, some surveys had very low response rates, were completed only by proxy respondents or ranked only the perceived importance of MSD-related sickness absence, rather than measuring it. CONCLUSIONS: National statistics on MSD-related sickness absence are piecemeal and incomplete. This limits capacity to plan and monitor national policies in an important area of public health. Simple low-cost additions to the LFS would improve the situation.

BACKGROUND: To identify opportunities for targeted prevention, we explored differences in occupational mortality from diseases and injuries related to alcohol consumption, sexual habits and drug abuse. METHODS: Using data on all deaths among men and women aged 16-74 years in England and Wales during 1991-2000, we derived age- and social class-standardized proportional mortality ratios (PMRs) by occupation for cause of death categories defined a priori as potentially related to alcohol consumption, sexual habits or drug abuse. RESULTS: The highest mortality from alcohol-related diseases and injuries was observed in publicans and bar staff (both sexes) and in male caterers, cooks and kitchen porters and seafarers. Male seafarers had significantly elevated PMRs for cirrhosis (179), 'other alcohol-related diseases' (275), cancers of the liver (155), oral cavity (275) and pharynx (267) and injury by fall on the stairs (187). PMRs for human immunodeficiency virus infection (HIV)/acquired immunodeficiency syndrome (AIDS) were particularly high in tailors and dressmakers (918, 95% CI: 369-1890, in men; 804, 95% CI: 219-2060, in women) and male hairdressers (918, 95% CI: 717-1160). Most jobs with high mortality from HIV/AIDS also had more deaths than expected from viral hepatitis. Of seven jobs with significantly high PMRs for both drug dependence and accidental poisoning by drugs, four were in the construction industry (male painters and decorators, bricklayers and masons, plasterers, and roofers and glaziers). CONCLUSIONS: Our findings highlight major differences between occupations in mortality from diseases and injuries caused by alcohol, sexual habits and drug abuse. Priorities for preventive action include alcohol-related disorders in male seafarers and drug abuse in construction workers.

OBJECTIVES: To investigate whether common important health conditions and their treatments increase risks of occupational injury. METHODS: A systematic search was conducted of MEDLINE, EMBASE and PsycINFO databases from inception to November 2006 employing terms for occupational injury, medications, and a broad range of diseases and impairments. Papers related solely to driving, alcohol, or substance abuse were excluded, as were studies that did not allow analysis of injury risk. For each paper that was retrieved we abstracted standard information on the population, design, exposure(s), outcome(s), response rates, confounders and effect estimates; and rated the quality of information provided. RESULTS: We found 38 relevant papers (33 study populations): 16 studies were of cross-sectional design, 13 were case-control and 4 were prospective. The overall quality was rated as excellent for only two studies. Most commonly investigated were problems of hearing (15 studies), mental health (11 studies) and vision (10 studies). For impaired hearing, neurotic illness, diabetes, epilepsy and use of sedating medication there were moderate positive associations with occupational injury (odds ratios 1.5-2.0), but there were major gaps in the evidence base. Studies covering vision did not present risks by category of eye disease; no evidence was found on psychotic illness; for diabetes, epilepsy and cardiovascular disease there were remarkably few papers; studies seldom distinguished risks by sub-category of external cause or anatomical site and nature of injury; and exposures and outcomes were mostly ascertained by self-report at a single time point, with a lack of clarity about exposure timings. CONCLUSION: Improved research is needed to define the risks of occupational injury arising from common health complaints and treatments. Such research should delineate exposures and outcomes in more detail, and ensure by design that the former precede the latter.

The association between suicide and medical disorder has not received as much attention as the association between suicide and psychiatric disorder. We identified by statistical overview medical disorders with an altered suicide risk. We found reports on the mortality of 63 medical disorders (ICD9 001-289, 320-999) said to have an altered suicide risk. English-language reports were located on MEDLINE with the search terms "disease name with mortality and follow-up"; and from the reference lists of these reports. We abstracted 235 reports of mortality studies of medical disorders with 2 years or more of follow-up, less than 10% loss of subjects, observed numbers of suicides given, and either the expected number or the facts from which to derive this. The ratio of the sum of the observed to the sum of the expected suicides, for each disorder, tested by the Poisson distribution gave an assessment of altered risk of death from suicide. Increased risk (p < 0.05) was seen for HIV/AIDS, malignant neoplasms as a group, head and neck cancers, Huntington disease, multiple sclerosis, peptic ulcer, renal disease, spinal cord injury, and systemic lupus erythematosus. Inconclusive evidence for increased risk was observed for amputation, heart valve replacement and surgery, disorders of the intestine (Crohn disease, ileostomy, ulcerative colitis), hormone replacement therapy, alcoholic liver disease, neurofibromatosis, systemic sclerosis, and Parkinson disease. Pregnancy and the puerperium had decreased risks (p < 0.05). There was no evidence of either increased or decreased risk for any of the other disorders studied.

AIMS: To obtain further information about the risks of cancer associated with occupational exposure to ethylene oxide METHODS: Follow up was extended by 13 years for a cohort of 2876 men and women with definite or potential exposure to ethylene oxide in the chemical industry or in hospital sterilising units. Subjects were traced through National Health Service and social security records, and their mortality was compared with that expected from rates in the national population by the person-years method. RESULTS: Analysis was based on 565 deaths, of which 339 had occurred during the additional period of follow up. Mortality was close to or below expectation for all causes (565 deaths v 607.6 expected), all cancers (188 v 184.2), and for all specific categories of malignancy including stomach cancer (10 v 11.6), breast cancer (11 v 13.2), non-Hodgkin's lymphoma (7 v 4.8), and leukaemia (5 v 4.6). All five deaths from leukaemia occurred in the subset of subjects with greatest potential for exposure to ethylene oxide, but even in this group the excess of deaths was small (2.6 expected). CONCLUSIONS: The balance of evidence from this and other epidemiological investigations indicates that any risk of human cancer from ethylene oxide is low, particularly at the levels of occupational exposure that have occurred in Britain over recent decades. This may reflect the capacity of human cells to repair DNA damage caused by the chemical, which is a potent genotoxin and animal carcinogen.

While considerable improvements have been made over the last 30 years in hypertension (HTN) awareness, treatment, and control, a recent reversal of these trends has been documented with African-American adults, particularly among those continuing to suffer from uncontrolled hypertension and its adverse consequences. This paper presents data from a cross-sectional representative survey of the health status of an urban African-American community. The study was designed in partnership with community leadership to improve HTN care and control. The baseline survey was a face-to-face interview (including blood pressure [BP] measurements) of 2,196 adults residing in randomly selected blocks in the Sandtown-Winchester neighborhood in Baltimore City. These sample data were compared with national data from the NHANES III survey, and demonstrated similar awareness of hypertension. However, hypertension control rates among treated hypertensives were significantly lower in the study community (28%) than in the national survey (44%). Compared with normotensive individuals, those with HTN were significantly older, had less education, were less likely to be employed, and had lower annual incomes. Individuals with HTN were also significantly more likely to rate their health as poor/fair, to report a history of heart disease, stroke, diabetes, kidney disease, obesity, high cholesterol, and lack of exercise, as well as to be at greater risk of alcoholism or alcohol problems. Hypertensive individuals (88% with reported prior history, 12% newly detected) were significantly more likely to have a usual source of care, have seen a health professional in the last 12 months, and to be extremely satisfied with the provider; however, 20% of individuals with hypertension reported no health insurance. These data indicate the need for focused interventions to enhance hypertension maintenance of care and adherence to treatment.

BACKGROUND: Mental disorders have a strong association with suicide. This meta-analysis, or statistical overview, of the literature gives an estimate of the suicide risk of the common mental disorders. METHOD: We searched the medical literature to find reports on the mortality of mental disorders. English language reports were located on MEDLINE (1966-1993) with the search terms mental disorders', 'brain injury', 'eating disorders', 'epilepsy', 'suicide attempt', 'psychosurgery', with 'mortality' and 'follow-up studies', and from the reference lists of these reports. We abstracted 249 reports with two years or more follow-up and less than 10% loss of subjects, and compared observed numbers of suicides with those expected. A standardised mortality ratio (SMR) was calculated for each disorder. RESULTS: Of 44 disorders considered, 36 have a significantly raised SMR for suicide, five have a raised SMR which fails to reach significance, one SMR is not raised and for two entries the SMR could not be calculated. CONCLUSIONS: If these results can be generalised then virtually all mental disorders have an increased risk of suicide excepting mental retardation and dementia. The suicide risk is highest for functional and lowest for organic disorders with substance misuse disorders lying between. However, within these broad groupings the suicide risk varies widely.

BACKGROUND: We describe the increased risk of premature death from natural and from unnatural causes for the common mental disorders. METHOD: With a Medline search (1966-1995) we found 152 English language reports on the mortality of mental disorder which met our inclusion criteria. From these reports, covering 27 mental disorder categories and eight treatment categories, we calculated standardised mortality ratios (SMRs) and 95% confidence intervals (CIs) for all causes of death, all natural causes and all unnatural causes; and for most, SMRs for suicide, other violent causes and specific natural causes. RESULTS: Highest risks of premature death, from both natural and unnatural causes, are for substance abuse and eating disorders. Risk of death from unnatural causes is especially high for the functional disorders, particularly schizophrenia and major depression. Deaths from natural causes are markedly increased for organic mental disorders, mental retardation and epilepsy. CONCLUSION: All mental disorders have an increased risk of premature death.

BACKGROUND: The lifetime risks of suicide are generally quoted as 15% for affective disorder and alcoholism and 10% for schizophrenia, based on data from 1921-1975 and on calculations performed before computerised modelling techniques became available. This study recalculates the risk using contemporary data and modern techniques. METHOD: Twenty-seven mortality studies provided data for affective disorder, 27 for alcohol dependence and 29 for schizophrenia. The proportion of the cohort who had died was plotted against the proportion of deaths from suicide. Modelling techniques fitted curves through the data points extrapolating them to cohort extinction, thus estimating the lifetime risk of suicide for each disorder. RESULTS: The lifetime risk was estimated at 6% for affective disorder. 7% for alcohol dependence and 4% for schizophrenia. CONCLUSIONS: The lifetime suicide risk figures often quoted in the literature appear to be too high.

A cohort study has been carried out of 2876 men and women with potential exposure to ethylene oxide. Subjects were identified from employment records at four companies that have produced or used ethylene oxide since the 1950s and at eight hospitals which have had ethylene oxide sterilising units since the 1960s. The cohort represents a substantial proportion of the British workforce with a history of occupational exposure to ethylene oxide. Industrial hygiene data were not available before 1977, but since then time weighted average exposures have been less than 5 ppm in almost all jobs and less than 1 ppm in many. Past exposures were probably somewhat higher. In contrast to some previous studies, no clear excess of leukaemia (three deaths observed, 2.09 expected) and no increase in stomach cancer (five deaths observed, 5.95 expected) were found. This discrepancy with earlier reports may be due in part to differences in levels of exposure. Total cancer mortality was similar to that expected from national and local death rates. Some specific cancers showed small excesses but their relevance to ethylene oxide exposure is doubtful. Again, contrary to some earlier reports, no excess of cardiovascular disease was found. This study does not exclude the possibility that ethylene oxide is a human carcinogen but suggests that any risk of cancer from currently permitted occupational exposures is small.

In a survey of eighty-eight county districts within England and Wales, rates of Alzheimer's disease in people under the age of 70 years were estimated from the records of the computerised tomographic (CT) scanning units that served these districts. Rates were adjusted to compensate for differences in distance from the nearest CT scanning unit and for differences in the size of the population served by the units. Aluminium concentrations in water over the past 10 years were obtained from water authorities and water companies. The risk of Alzheimer's disease was 1.5 times higher in districts where the mean aluminium concentration exceeded 0.11 mg/l than in districts where concentrations were less than 0.01 mg/l. There was no evidence of a relation between other causes of dementia, or epilepsy, and aluminium concentrations in water.
