Background: Opioid prescribing is increasing worldwide with associated increases in misuse and other harms. We studied variations in national opioid prescription rates, indicators of prescribing quality, co-prescribing of benzodiazepines and relationship with pain severity in Scotland.Methods: Electronic linkages of opioid prescribing in Scotland were determined from: (i) national data from Information Services Division, NHS Scotland (2003-2012); and (ii) individual data from Generation Scotland: Scottish Family Health Study. Descriptive analyses were conducted on national data, multilevel modelling to examine factors associated with variations in prescribing rates. χ2 tests examined associations between individual pain severity and opioid prescriptions.Results: The number of strong opioid prescriptions more than doubled from 474 385 in 2003 to 1 036 446 in 2012, and weak opioid prescribing increased from 3 261 547 to 4 852 583. In Scotland, 938 674 individuals were prescribed an opioid in 2012 (18% of the population). Patients in the most deprived areas were 3.5 times more likely to receive a strong opioid than patients in the least deprived. There was significant variation in prescribing rates between geographical areas, with much of this explained by deprivation. Of women aged 25-40 yr prescribed a strong opioid, 40% were also prescribed a benzodiazepine. There was significant association between pain severity and receipt of opioid prescription. Over 50% of people reporting severe pain were not prescribed an opioid analgesic.Conclusions: We found opioid prescribing in primary care to be common and increasing in Scotland, particularly for severe pain. Co-prescribing of opioids and benzodiazepines was common. [ABSTRACT FROM AUTHOR]- Published

The 3-yearly World Congress of Epidemiology is the premier, international, scientific conference organised under the auspices of the International Epidemiological Association (in open competition). This paper explores the justification for seeking to host the Congress and reflects on the structures and processes adopted in making the XIXth Congress in Scotland happen. Preparing the bid was invaluable for forming collaborations, generating scientific ideas, and garnering opinion. After the bid was accepted, we formed a local organising committee, named the Management Executive Committee to signal its decision making authority; and scientific, fundraising, marketing, international and social subcommittees. There was uncertainty about critical matters such as delegate numbers, costs and the total budget. Early decisions had to be made on, for example, the fee and fundraising target (~250,000), despite financial risks. Development of the scientific programme was a critical step that under-pinned fundraising and marketing and permitted involvement of the international committee. Overall the 2011 WCE succeeded. The key ingredients to success were: a large collaboration of institutions and individuals; early pledges of financial support mostly from the UK; the valuable and relevant experience of the professional conference organisers; unstinting support and advice from IEA; and the effectiveness of the committee structure. The educational and professional development benefits of this WCE will reach a worldwide community and not just delegates, because of video, PowerPoint and textual accounts being open access on the Internet. This reach is unprecedented for IEA's World Congresses. We anticipate that the Congress will translate into better public health practice, better future Congresses, advances in epidemiology and improved population health. [ABSTRACT FROM AUTHOR]

- Abstract
The reasons for an increasing incidence of oral cancer, particularly amongst younger persons is unclear. It has been hypothesised either to be a result of an increase in exposure to known risk factors amongst certain groups in the community, or to be due to new aetiological agents. Prior to conducting large expensive population-based studies, it seems appropriate to conduct initial smaller-scale surveys to assess evidence for each of these two hypotheses. This survey of young persons with oral cancer suggest that most are exposed to traditional risk factors of tobacco smoking, drinking alcohol and a low consumption of fruit and vegetables.

- Abstract
Data were examined to determine trends in survival from cancers of the oral cavity and pharynx in Scotland between 1968 and 1987, and to analyse survival rates and the previously noted increases in the incidence of such cancers according to the level of social deprivation. Incidence data on oral cavity and pharyngeal cancer and survival rates following diagnosis were obtained from the Information and Statistics Division of the Common Services Agency for the National Health Service in Scotland, covering the period 1968-92. It was found that survival rates for cancers of the tongue, mouth and pharynx diagnosed among persons less than 65 years of age decreased between 1968-72 and 1983-87. Five year relative survival rates fell from 47% to 39% over this period, while the equivalent rates among persons older than 65 years have shown a modest improvement from 34% to 38%. When considered by level of social deprivation, survival is lower among persons from the most deprived areas, and it is among such persons that the recent increases in occurrence of cancers of the oral cavity and pharynx have primarily occurred. The poorer survival among those from more socially deprived areas, and the evidence that the largest increase in incidence has occurred in such areas may to some extent explain the non-favourable trends in mortality. More importantly it emphasises the potential benefits of targeting such a population for oral health information. An educational campaign should include both information on the risk factors for developing oral cancer, and also the importance of seeking an early professional consultation in the case of symptoms.

- Abstract
We conducted an international comparison of the prevalence of urinary symptoms of prostatism in 4 countries, using a community-based random sampling of subjects, similar study procedures, and a single definition of cases that was based on a standardized symptom questionnaire. In Scotland 1,994 medically eligible men aged 40-79 years agreed to participate from 3 communities of the Forth Valley. In France, a nation-wide survey was conducted cross-sectionally in a representative sample of 2,011 French men aged 50-84 years. In the USA, the Olmsted County (OC) study recruited an age- and urban/rural-stratified random sample of 2,115 county residents drawn from medically eligible men aged 40-79 years. In Japan, 290 men aged 40-79 years from a fishing village participated in the study. Response rates were 55, 53, 55, and 43% in Scotland, France, OC and Japan, respectively. Urinary symptoms were assessed by the International Prostate Symptom Score (I-PSS), after metrologic validation in English and cross-cultural adaptation of the questionnaire. The prevalence of moderate to severe symptoms (I-PSS > 7) were 14, 18, 38, and 56% in France, Scotland, OC and Japan, respectively. This pattern was consistent within decades of age, and was found for most of the individual urinary symptoms. The proportion of men in Japan reporting very low I-PSS (0 or 1) was approximately 2, 4 and 8 times less frequent, than in OC, Scotland, and France, respectively. Differences in the prevalence of reported urinary symptoms might reflect between-country differences in the true prevalence of benign prostatic hyperplasia. However, cross-cultural differences in the perception and/or willingness to report urinary symptoms may play an important role in the observed differences. Further study will be required to elucidate the underlying causes of the observed differences.

- Abstract
Data over at least 20 years from three large population-based registries in Europe and Australasia have been used to assess the risk of second primary tumours occurring after a cancer of the mouth or pharynx. These patients have previously been shown in clinical series to be at a particularly high risk of subsequent tumours, while data from cancer registries have shown conflicting results on the magnitude of the risk. In this study, patients were found to have between a 2-fold (Scotland and New South Wales) and 4-fold (Slovenia) increase in risk of a subsequent tumour over that in the population, although the actual risk in each centre was similar (between 2.8 and 3.1 per 100 person years). The risk remained for 10 years after diagnosis of the original tumour and was primarily in the upper aerodigestive tract. The most elevated risks (approximately 10-fold) were for tumours in the oral cavity and oesophagus. These data provide higher estimates of risk than previously reported from European cancer registries for second primary tumours and emphasize the need for close follow-up of patients who may represent an appropriate population in which to assess possible new chemopreventive agents.

- Abstract
In Scotland over the last 31 years the incidence of gastric cancer has significantly declined by 0.6% per annum in males and 1.1% in females. In contrast, for oesophageal cancer, incidence rates have risen significantly by 3.0% and 2.0% per annum in males and females respectively. Increasing incidence of both adenocarcinomas and squamous carcinomas of the oesophagus in men and squamous and recently adenocarcinomas in women has been observed. This cannot be entirely accounted for by a growth in the proportion of histologically verified (HV) tumours over time. The incidence of adenocarcinoma of the stomach increased over the study period, most likely because of increasing proportions of HV tumours and improved diagnostic precision. Areas with high levels of deprivation in Scotland are strongly associated with high rates of oesophageal cancer in men, and of gastric cancer in both men and women. All these observations are discussed in the context of current knowledge of risk factors for these diseases.

- Abstract
This paper describes the temporal pattern of germ cell testicular cancer in Scotland between 1960 and 1990. The effect of age on the prognosis of patients with non-seminomatous germ cell tumours (NSGCT) has been assessed by studying all patients presenting in the West of Scotland between 1975 and 1989. Between 1960 and 1990, the number of testicular germ cell tumours registered has increased more than 2-fold; mortality rates have declined equally dramatically. Univariate and multivariate analysis of the data obtained on 440 patients with NSGCT showed age was not a prognostic factor influencing survival. 52 were patients over 40 years at presentation; their 5 years survival was 71% compared with 79% in the younger patients (n = 388). This small survival difference is probably explained by the higher proportion of older patients treated before 1980. Treatment for this older group should be approached with the same curative intent as for younger patients and the same expectation of success.

- Abstract
There have been recent reports of substantial increases occurring in the incidence of and/or mortality from tongue and mouth cancers in several countries. In this paper using data from Scotland (1960-89) we report on time trends in pharyngeal cancer. Similar increases in rates are evident for cancers of the oropharynx and hypopharynx while there has been little change in the occurrence of nasopharyngeal cancer (which has distinct aetiological factors). It therefore seems that reported changes in the incidence of and mortality from oral cancer may be real, and in Scotland, this is most probably due to changes in alcohol consumption.

- Abstract
The purpose of this paper is to present the descriptive epidemiology of lip cancer in Scotland. The incidence and mortality of lip cancer are found to be higher in men than in women and to have fallen remarkably among men. This decline has been the result of cohort effects indicating that the risk of lip cancer is decreasing among successively younger people.

- Abstract
Objectives: To determine the incidence of oral cancer in Scotland between 1960 and 1989 and oral cancer mortality from 1911 to 1989., Setting: Data were obtained on oral cancer incidence from the information and statistics division of the Common Services Agency of the Scottish Health Service and mortality data from the office of the registrar general for Scotland., Results: Mortality from intraoral cancers in Scotland substantially declined throughout this century until the mid-1970s. This trend, however, was then reversed, and fourfold increases in incidence were observed in younger age groups after 1960. Death rates in these younger age groups increased to levels previously recorded in the 1940s. These increases seemed to be cohort based and may therefore continue into the future., Conclusions: Reasons for increasing rates among younger age groups are speculative and rely on combining knowledge about risk factors and available ecological data. Though increases in incidence at younger ages do not result in a large change in the number of cases diagnosed, possible similar increases continuing into older ages, when oral cancer is more common, will correspond to a much larger increase in the actual number of cases. Given that such a large attributable risk is associated with tobacco and alcohol, however, these increases may be preventable.
