Preoperative imaging modalities to predict the risk of regional nodal recurrence in well-differentiated thyroid cancers.

Introduction Thyroid cancer incidence has increased in the previous 2 decades. Preoperative identification of lymph node metastasis is a suggested risk factor associated with recurrence following thyroidectomy. Objectives We aimed to evaluate the accuracy of preoperative radiologic investigations of nodal status in determining the postoperative risk of regional nodal recurrence in cases of well-differentiated thyroid cancer.

Prevalence of hearing loss among Saudi type 2 diabetic patients.

Objective: To compare hearing impairment and audiometric shapes associated with type 2 diabetes mellitus (T2DM) with an age-matched control group in the Saudi population.

Methods: This is an observational case-control study at a tertiary academic referral center. We recruited 196 individuals (age; 29-69 years) attending the Department of Otolaryngology, King Abdulaziz University Hospital between January 2005 to December 2009, and grouped them into T2DM (n=109) and control (n=87) groups.
