["The aim of the study was to analyze the time-to-diagnosis interval in patients with Cushing's disease (CD) and acromegaly (AC), to assess factors that promote early disease detection and to investigate the medical fields diagnosing the pathologies.", '33 CD and 52 AC patients operated over 10 years received a self-designed disease-related questionnaire. Data about symptoms and their duration prior to diagnosis, education level, age, gender and place of residence (i. e. rural vs. urban, size of the city) were collected.', 'The mean time-to-diagnosis interval was 6.0 years in CD and 5.8 years in AC patients. The vast majority of 67% of all investigated patients was diagnosed after they changed their primary health care provider or during a hospital stay owing to comorbidities caused by their underlying disease. Only 33% of all cases were diagnosed by their primary physician. In both groups neither gender, age, place of residence, education level, typical comorbidities (e. g. hypertension or diabetes) nor distinctive symptoms and bodily changes of the underlying disease (e. g. prognathism, acral enlargement, weight gain, buffalo hump) were significant factors promoting early detection.'] Do demographic factors and the presence of comorbidities promote early detection of Cushing 's disease and acromegaly?
