Idiopathic benign paroxysmal positional vertigo in the elderly: a long-term follow-up study.

Background: Benign paroxysmal positional vertigo (BPPV) is the most common cause of peripheral-type vertigo in the elderly. While some studies have investigated BPPV among the elderly, no study has focused on the isolated idiopathic BPPV (iBPPV) in the elderly.

Aims: To investigate the clinical features and recurrence rate in elderly patients diagnosed with iBPPV.

Comparison of natural drainage group and negative drainage groups after total thyroidectomy: prospective randomized controlled study.

Purpose: The aim of this study was to compare a negative pressure drain with a natural drain in order to determine whether a negative pressure drainage tube causes an increase in the drainage volume.

Materials And Methods: Sixty-two patients who underwent total thyroidectomy for papillary thyroid carcinoma (PTC) were enrolled in the study between March 2010 and August 2010 at Gyeongsang National University Hospital. The patients were prospectively and randomly assigned to two groups, a negative pressure drainage group (n=32) and natural drainage group (n=30).
