SYNOPSISNumerous studies have estimated the frequency of bulimia nervosa among high school girls and college women, but population-based trends in incidence in a community have not been reported.In this study we determined the incidence of bulimia nervosa by identifying persons residing in the community of Rochester, Minnesota, who had the disorder initially diagnosed during the 11-year period from 1980 to 1990. Using our comprehensive population-based data resource (the Rochester Epidemiology Project), we identified cases by screening 777 medical records with diagnoses of bulimia; feeding disturbance; rumination syndrome; adverse effects of cathartics, emetics, or diuretics; polyphagia; sialosis; or vomiting.We identified 103 Rochester residents (100 female and 3 male) who fulfilled DSM-III-R diagnostic criteria for bulimia nervosa during the 11-year study period. Mean ± S.D. age for females at the time of diagnosis was 23·0 ± 6·1 years (range, 14·4 to 40·2 years). Yearly incidence in females rose sharply from 7·4 per 100000 population in 1980 to 49·7 in 1983, and then remained relatively constant around 30 per 100000 population. The annual age-adjusted incidence rates were 26·5 per 100000 population for females and 0·8 per 100000 population for males. The overall age-and sex-adjusted annual incidence was 13·5 per 100000 population.Bulimia nervosa is a common disorder in adolescent girls and young women from 15 to 24 years of age. Histories of alcohol or drug abuse, depression, or anorexia nervosa were higher than expected in the general population.

Abstract If the observed dramatic increase in VTE incidence with advancing age is due to increased VTE risk factor exposure (i.e., secondary VTE), the incidence of idiopathic VTE should not vary with age or calendar year. Objective: To estimate the incidence of idiopathic and secondary VTE by age and by calendar year. Methods: Using the resources of the Rochester Epidemiology Project, we identified the inception cohort of Olmsted County, MN, residents with a first lifetime VTE during the 30-year period, 1966–1995 (n=2761). For each case, we reviewed the complete medical records in the community for 48 baseline clinical characteristics that are commonly-accepted risk factors for VTE. We categorized VTE cases as idiopathic (n=305) if no such characteristics were present; the remaining cases were categorized as secondary. Age- and sex-specific incidence rates were calculated using idiopathic or secondary VTE cases as the numerator, and age-, sex- and calendar year-specific estimates of the population of Olmsted County as the denominator. Results: The incidence of both idiopathic and secondary VTE increased exponentially with age for both men and women (p<0.001). Over the 30-year study period, the age-adjusted incidence of idiopathic VTE was essentially constant among men (from 19.0 to 17.1 per 100,000 men-years for 1966–70 and 1990–95, respectively), but decreased markedly among women (from 18.5 to 3.6 per 100,000 woman-years for 1966–70 and 1990–95, respectively; p=0.005 for the interaction). Conclusions: The dramatic increase in VTE incidence with age likely reflects the biology of aging, although as yet unidentified VTE risk factors cannot be excluded. The reason for the decreased incidence of idiopathic VTE over the last 30 years among women is unclear.

Background: There are no previous reports of the incidence rate of intracranial saccular aneurysms in a defined population.Methods: Medical records of all residents of Olmsted County, MN, with a possible intracranial saccular aneurysm (IA) were reviewed. Incidence rates and prevalence of symptomatic and asymptomatic IAs, aneurysmal intracranial hemorrhage (ICH), and frequency of IA detection based on size and site were determined.Results: A total of 348 IAs were detected among 270 persons during the 31-year period from 1965 to 1995, including 188 symptomatic patients at presentation(166 with ICH). The age- and sex-adjusted incidence rate for IAs excluding asymptomatic autopsy cases was 9.0/100,000 person-years (P-Y; 95% CI, 7.8 to 10.2). The rate of detection in women (10.7/100,000 P-Y; 95% CI, 8.9 to 12.4) was higher than in men. The highest incidence of IA was among those age 55 to 64 years in men, and 65 to 74 years in women. The incidence rate of aneurysmal ICH was 6.9/100,000 P-Y (95% CI, 5.9 to 8.0). Aneurysms were seven times more likely to be detected in the anterior circulation, and this ratio was not altered significantly by age or gender. On January 1, 1990, the age- and sex-adjusted prevalence rate of identified IAs was 83.4/100,000 population (95% CI, 64.1 to 102.7).Conclusions: This study provides unique data on the population-based incidence and prevalence rates of IAs.

AimTo determine population-based incidence of conjunctival tumours in Olmsted County, Minnesota.MethodsThe Rochester Epidemiology Project medical record linkage system was used to identify patients with conjunctival tumours in Olmsted County (1 January 1980 to 31 December 2015). Records were reviewed for demographics, types of tumours, histopathology, treatment and clinical course. Incidence rate of all tumours was calculated per 1 000 000 person-years. Poisson regression analysis was used to assess changes in incidence over time.ResultsThere were 504 patients with conjunctival tumours, giving an age-adjusted and sex-adjusted incidence rate of 125 per 1 000 000 (CI 113.5 to 135.5). Incidence increased over time (P<0.001). Most tumours (474, 94%) were benign. Of benign lesions, melanocytic lesions accounted for the majority (431, 86%), with adjusted incidence rates of 10.8 (CI 7.7 to 13.9) for complexion-associated melanosis, 49.7 (CI 42.9 to 56.6) for nevus and 44.1 (37.5–50.8) for primary acquired melanosis. Malignant lesions were rare (30, 6%) with 6 cases of melanoma, 21 cases of ocular surface squamous neoplasia (OSSN), 1 case of Langerhans cell histiocytosis and 2 cases of lymphoma. Adjusted incidence rates of conjunctival melanoma and OSSN were 1.5 (CI 0.3 to 2.8) and 6.1 (CI 3.5 to 8.7), respectively. Outcomes for melanoma (mean follow-up 14 years, range 0–34) and OSSN (mean follow-up 4 years, range 0–24) were favourable in 29 cases, with one fatality due to metastatic melanoma.ConclusionsIn a population-based setting, most conjunctival tumours are benign, and the majority of lesions are melanocytic. While it is important to remain vigilant for malignancies, most conjunctival lesions in a community-based practice are not life-threatening.

Background: There is growing concern about the rising incidence and prevalence of food allergy globally. We previously reported the incidence of food allergy in Olmsted County, Minnesota, between 2002 and 2011. We sought to update the incidence and temporal trends of food allergies in our region through 2018. Methods: By using the Rochester Epidemiology Project, all Olmsted County residents, with an incident diagnosis of food allergy between January 2, 2012, and December 31, 2018, were identified and their medical records were reviewed. These cases were combined with the previously collected incidence cases from January 2, 2002, and December 31, 2011, to understand longitudinal trends in food allergy incidence rates. Results: Over the 17-year study period, 1076 patients (58.0% male patients, 72.1% white) were diagnosed with an incident food allergy. The median (interquartile range) age at first diagnosis was 2.0 years (1.1-8.4 years). The overall annual incidence rate for all ages was 3.9 (95% confidence interval [CI], 3.6‐4.1) per 10,000 person-years and was significantly higher in male than in female patients (4.4 [95% CI, 4.0‐4.7] and 3.3 [95% CI, 3.0‐3.6], respectively; p < 0.001). The most common food allergen was egg in infancy (57.7%), peanuts in ages 1‐4 years (58.3%), tree nuts in ages 5‐18 years (57.4%), and seafood in adults (≥19 years) (45.3%). Conclusion: The incidence of food allergy in Olmsted County steadily increased from 2002 to 2008, then remained relatively stable between the years 2008 and 2013, and again presented a rising trend over the next 5 years until 2018. This warrants further investigations into the effects of changes in guidelines for early introductions of allergenic foods and other factors that affect causality.

Objective.To examine the incidence of gout over the last 20 years and to evaluate possible changes in associated comorbid conditions.Methods.The medical records were reviewed of all adults with a diagnosis of incident gout in Olmsted County, Minnesota, USA, during 2 time periods (January 1, 1989–December 31, 1992, and January 1, 2009–December 31, 2010). Incident cases had to fulfill at least 1 of 3 criteria: the American Rheumatism Association 1977 preliminary criteria for gout, the Rome criteria, or the New York criteria.Results.A total of 158 patients with new-onset gout were identified during 1989–1992 and 271 patients during 2009–2010, yielding age- and sex-adjusted incidence rates of 66.6/100,000 (95% CI 55.9–77.4) in 1989–1992 and 136.7/100,000 (95% CI 120.4–153.1) in 2009–2010. The incidence rate ratio was 2.62 (95% CI 1.80–3.83). At the time of their first gout flare, patients diagnosed with gout in 2009–2010 had higher prevalence of comorbid conditions compared with 1989–1992, including hypertension (69% vs 54%), diabetes mellitus (25% vs 6%), renal disease (28% vs 11%), hyperlipidemia (61% vs 21%), and morbid obesity (body mass index ≥ 35 kg/m2; 29% vs 10%).Conclusion.The incidence of gout has more than doubled over the recent 20 years. This increase together with the more frequent occurrence of comorbid conditions and cardiovascular risk factors represents a significant public health challenge.

Abstract Context Pheochromocytoma and sympathetic paraganglioma (PPGL) are rare catecholamine-secreting tumors but recent studies suggest increasing incidence. Traditionally, PPGL are described to present with paroxysmal symptoms and hypertension, but existing data on clinical presentation of PPGL come from referral centers. Objective We aimed to describe time trends in clinical presentation and incidence of PPGL in a population-based study. Methods We conducted a nationwide retrospective cohort study of a previously validated cohort of 567 patients diagnosed with PPGL in Denmark 1977-2015. We collected clinical data from medical records of a geographic subcohort of 192 patients. We calculated age-standardized incidence rates (SIRs) and prevalence for the nationwide cohort and descriptive statistics on presentation for the subset with clinical data. Results SIRs increased from 1.4 (95% CI 0.2-2.5) per million person-years in 1977 to 6.6 (95% CI 4.4-8.7) per million person-years in 2015, corresponding to a 4.8-fold increase. The increase was mainly due to incidentally found tumors that were less than 4 cm and diagnosed in patients older than 50 years with no or limited paroxysmal symptoms of catecholamine excess. On December 31, 2015, prevalence of PPGL was 64.4 (CI 95% 57.7-71.2) per million inhabitants. Of 192 patients with clinical data, 171 (89.1%) had unilateral pheochromocytoma, while unilateral paraganglioma (n = 13, 6.8%) and multifocal PPGL (n = 8, 4.2%) were rare. Conclusion Incidence of PPGL has increased 4.8-fold from 1977 to 2015 due to a “new” group of older patients presenting with smaller incidentally found PPGL tumors and few or no paroxysmal symptoms.

Incidence rates for aplastic anemia (AA) so far have been unavailable for defined populations in the United States. A study was carried out in the Baltimore Standard Metropolitan Statistical Area (SMSA) to examine the incidence rates for aplastic anemia from 1970 through 1978. Cases of AA (N = 118) were identified through medical records (N = 77) in SMSA hospitals and death certificates (N = 41). All medical charts were reviewed by an oncologist-hematologist for validation purposes. Among whites, average annual age-adjusted incidence rates per million were higher in males (7.1) than in females (5.4), whereas in nonwhites, females had a higher rate (7.3) than males (4.7). None of the sex differences was statistically significant. Age-specific incidence rates were consistently low in young ages, with an exponential increase after age 40. Examination of time trends did not suggest changes in whites, although in blacks, mainly in males, there was a suggestion of a temporal increase. However, rates in blacks were based on small numbers, and trends were not statistically significant. An inconsistent sex differential, as well as the relative stability of rates over time at least in whites, suggests that although sexes may have different types of exposures, occupational exposures and changes in environmental factors over time cannot entirely explain the occurrence of AA in the population. In addition, the age pattern suggests that future studies should examine etiologic agents separately for the younger and the older subjects with AA.

225 Background: PC is the third leading-cause of cancer death in Spain. In this study we aim to investigate PC’s incidence and trends during 1994-2015 in Girona. Methods: Data were extracted from the population-based Girona Cancer Registry. Incident PC cases were classified using the ICD-O-3 Third Edition. Age-adjusted incidence rates (ASRE) to the European standard population and world standard population (ASRW) were obtained. Trends were assessed using the estimated annual percentage of change (EAPC) of the ASRE13. Results: We identified 1590 PC incident cases, 45.8% females and 54.2%. Patients > 64 years old represented a 72.6% of cases. According to histology, epithelial tumors stand for a 44% of cases and neuroendocrine neoplasms represented only the 3% of all cases, being most of PC tumors’ histology non-specified. Cases detected only by death certificates (DCO) were 7.7% in males and 7.4% in females. For the whole study population, crude rate (CR) cancer incidence was 11.26 cases per 100,000 inhabitants/year (12.17 men; 10.34 women). Regarding the ASR, results show an ASRE13 of 12.99 (95% CI 12.36;13.65) and ASRW of 5.58 (95% CI 5.8;13.655.91). Age-specific rates reflected a drastic increase with age, having the population over 85 years the highest rate (74.5 cases per 100,000 inhabitants/year). We also found a significant increase in incidence of PC cases over the study period, with an EAPC of 1.41% per year, present in both men (EAPC = 1.30%) and women (EAPC = 1.37%). Conclusions: Incidence rates of PC in Girona are within the European average, and likewise they have been increasing for the last two decades. There is an increase of incidence in the elderly population reflected in age-specific rates, reason whereby we believe there are a high proportion of unspecific histologies. These results can be used as baseline for further research.
