Incidence of congenital diaphragmatic hernia in Olmsted County, Minnesota: a population-based study.

ABSTRACT: OBJECTIVE:The rate of congenital diaphragmatic hernia (CDH) varies, but most reports estimate the incidence to be less than three per 10,000 births. Our objective was to document the incidence of CDH in a geographically well-defined population using available resources for highly accurate incident case ascertainment. METHODS:We ascertained CDH cases in Olmsted County, Minnesota, United States of America, from 1981 through 2014 using resources of the Rochester Epidemiology Project. Overall and sex-specific incidence rates were calculated, and hospital survival was assessed. RESULTS:A total of 26 incident CDH cases were identified; the overall incidence of 3.6 (95% CI, 2.2-5.0) per 10,000 did not differ significantly over the 34-year study period (p?=?.28). The estimated incidence was 4.3 (95% CI, 2.2-6.5) for male infants and 2.9 (95% CI, 1.1-4.6) for female infants. The percentage of cases diagnosed prenatally was 33% from 1981 through 2000 and 50% from 2001 through 2014. The rate of survival to discharge in the two periods was 50% and 88%. CONCLUSION:The incidence of CDH in Olmsted County exceeds the majority of published rates, which most likely can be attributed to our comprehensive case ascertainment.

Project description:BackgroundAdrenal tumours are commonly encountered in clinical practice, but epidemiological data mainly originate from referral centres. We aimed to determine incidence, prevalence, and rates of malignancy and hormone excess in patients with adrenal tumours in a standardised geographically well defined population.MethodsIn this retrospective population-based cohort study we assessed the standardised incidence rate of adrenal tumours in all patients with tumours who lived in Olmsted County, MN, USA, from Jan 1, 1995, to Dec 31, 2017. The Rochester Epidemiology Project infrastructure, which links medical records across all health-care providers for the entire population of Olmsted County since 1966, was used to allow researchers to identify individuals with specific diagnoses, surgical interventions, and other procedures, and to locate their medical records, which were then used in the analysis. Incidence rates and prevalence were standardised for age and sex according to the 2010 US Population.FindingsAn adrenal tumour was diagnosed in 1287 patients (median age 62 years; 713 (55·4%) were women; and 13 (1·0%) were children). Standardised incidence rates increased from 4·4 (95% CI 0·3-8·6) per 100 000 person-years in 1995 to 47·8 (36·9-58·7) in 2017, mainly because of the incidental discovery of adenomas less than 40 mm in diameter in patients older than 40 years. Prevalence of adrenal tumours in 2017 was 532 per 100 000 inhabitants, ranging from 13 per 100 000 in children (aged <18 years) to 1900 per 100 000 in patients older than 65 years. 111 (8·6%) of 1287 patients were diagnosed with malignancy (96 [7·5%] of whom has metastases), 14 (1·1%) with phaeochromocytoma, and 53 (4·1%) with overt steroid hormone excess. Malignancy was more common in children (62%) versus those older than 18 years (8%; p<0·0001), tumours discovered during cancer-staging or follow-up (43% vs 3% for incidentalomas; p<0·0001), tumours more than 40 mm in diameter (34% vs 6% for tumours <20 mm; p<0·0001), tumours with unenhanced CT attenuation of 30 Hounsfield units or more (20% vs 1% for <20 Hounsfield units; p<·0001), and bilateral masses (16% vs 7% for unilateral, p=0·0004).InterpretationAdrenal tumour standardised incidence rates increased 10 times from 1995 to 2017. Population-based data revealed lower rates of malignancy, phaeochromocytoma, and overt steroid hormone excess than previously reported.FundingNational Institutes of Health.
