Screening for thyroid diseases among students of applied medical sciences at King Abdulaziz University, Saudi Arabia

Abstract

Objectives: To identify the occurrence rate of thyroid ultrasound abnormalities in asymptomatic subjects, and describe the features of detected nodules among university students. Methods: The study is based on an observational research design that was conducted from April 2015 to May 2015. The study included 166 individuals, aged between 19 and 23 years. The subjects had their glands examined by ultrasound (US) scanning, using Philips ultrasound machine (5-12 MHz linear transducer). Results: We recruited 90 (57.8%) females and 76 (42.2%) males without any indications of thyroid disease. Data estimated that 41 (24.7%) subjects had positive results on thyroid disease screening, 24 (70.6%) participants had solitary nodules, and 10 (29.4%) had multiple nodules. Thirty-four subjects revealed nodular presentation in the screening, among which 24 (70.6%) indicated solitary nodules and 10 (29.4%) had multiple nodules. Among 3 subjects, who indicated hypoechoic nodules, 2 (66.7%) underwent US-fine needle aspiration biopsy and received histological confirmation that they had papillary carcinomas. Conclusion: Ultrasonography is a useful and effective technique for screening thyroid related diseases, and can be utilized as a routine practice for general population screening.
