Background Very few studies have been done of occupational health provision across an entire employment sector and universities are particularly understudied. The British government published updated guidance on university occupational health in 2006.

Aim To describe the occupational health services to all the universities in the UK.

Methods All 117 universities in the UK were included. Detailed surveys were carried out in 2002, 2003 and 2004 requesting self-completed information from each university occupational health service. This paper presents information on general characteristics of the service, staffing, services provided and outcome reporting.

Results There was variation in the type of occupational health provision; half the universities had an in-house occupational health service, 32% used a contractor, 9% relied on the campus primary care or student health service and 9% had ad hoc or no arrangements. In all, 93 of the 117 (79%) universities responded to the detailed questionnaire, the response rate being higher from in-house services and from larger universities. There was a wide variation in staffing levels but the average service was small, staffed by one full-time nurse with one half-day of doctor time per week and a part-time clerical or administrative member of staff. A range of services was provided but, again, there was wide variation between universities.

Conclusions It is unclear if the occupational health provision to universities is proportional to their needs. The wide variation suggests that some universities may have less adequate services than others.

Objective Dental erosion is characterized as a disorder with a multifactorial aetiology including environmental acid exposure. The purpose of this article was to summarize and discuss the available information concerning occupational dental erosion.

Methods Information from original scientific papers, case reports and reviews with additional case reports listed in PubMed, Medline or EMBASE [search term: (dental OR enamel OR dentin) AND (erosion OR tooth wear) AND (occupational OR worker)] were included in the review. References from the identified publications were manually searched to identify additional relevant articles.

Results The systematic search resulted in 59 papers, of which 42 were suitable for the present review. Seventeen papers demonstrated evidence that battery, galvanizing and associated workers exposed to sulphuric or hydrochloric acid were at higher risk of dental erosion. For other industrial workers, wine tasters and competitive swimmers, only a few clinical studies exist and these do not allow the drawing of definitive conclusions.

Conclusion Occupational acid exposure might increase the risk of dental erosion. Evidence for occupational dental erosion is limited to battery and galvanizing workers, while data for other occupational groups need to be confirmed by further studies.

Background The health of UK petroleum industry workers has been monitored for many years.

Aim To identify any long-term adverse health outcomes from occupational exposures in this industry.

Methods The mortality (1951–2003) and cancer morbidity (1971–2003) experienced by cohorts of 28 555 oil refinery workers and 16 477 petroleum distribution workers has been investigated. Study subjects were all those males first employed in the period 1946–74 at one of eight UK oil refineries or 476 UK petroleum distribution centres; all subjects had a minimum of 12 months employment with some employment after 1 January 1951. Observed numbers of cause-specific deaths and site-specific cancer registrations were compared with expectations based on national mortality and cancer incidence rates.

Results Standardized mortality ratios (SMRs) were significantly <100 for all causes both in oil refinery workers (Obs 11 156, SMR 89) and in petroleum distribution workers (Obs 7320, SMR 96). Significantly elevated SMRs were shown in oil refinery workers for cancer of the pleura (mesothelioma) (Obs 64, SMR 261) and melanoma (Obs 48, SMR 168). Significantly elevated SMRs were not found in petroleum distribution workers for any site of cancer. Significantly elevated standardized registration ratios (SRRs) were only shown in oil refinery workers and for cancer of the pleura (mesothelioma) (Obs 115, SMR 274), melanoma (Obs 85, SMR 129) and other skin cancer (Obs 983, SRR 117).

Conclusions The only findings that showed clear evidence of an occupational cancer hazard were those for mesothelioma in oil refinery workers.
