There is little data that determine the clinical characteristics of prelaryngeal lymph nodes (PLN) metastasis in patients with papillary thyroid cancer (PTC). The aims of this prospective study were to evaluate the incidence and the clinical characteristics of metastasis to the PLN for PTC patients who underwent total thyroidectomy and prophylactic central(More)
PURPOSE The anastomotic leakage rate after rectal resection has been reported to be approximately 2.5-21 percent, but most results were associated with open surgery. The aim of this study was to identify risk factors and their relationship to the experience of the surgeon for anastomotic leakage after laparoscopic rectal resection. METHODS Between March(More)
The surgical extent and indication for treatment in patients with papillary thyroid microcarcinoma (PTMC) remain a controversial issue. The aim of this study was to investigate the predictive factor for contralateral occult carcinoma in patients with unilateral PTMC by preoperative ultrasonographic and pathological features. Of the total patients who(More)
Endoscopic submucosal dissection (ESD) is the gold standard technique for en bloc resection of large superficial tumors in the upper and lower gastrointestinal tract. Little is known about the management of epigastric pain after ESD of gastric neoplasms. This study investigated the utility and safety of single-dose, perioperative, intravenous dexamethasone(More)
PURPOSE The pathogenetic mechanism of Bell's palsy is thought to involve herpes simplex virus reactivation within the geniculate ganglion, followed by inflammation and entrapment of the nerve at the meatal foramen. We therefore compared the therapeutic effect of acyclovir plus steroid vs steroid alone, in combination with physical therapy, in patients with(More)
OBJECTIVE/HYPOTHESIS To assess changes in the symptoms and quality of life (QOL) of patients diagnosed with laryngopharyngeal reflux (LPR) after proton pump inhibitor (PPI) treatment. STUDY DESIGN Prospective study. METHODS One hundred eighty patients diagnosed with LPR were evaluated. All patients were prescribed Lansoprazole (15 mg) twice daily for 12(More)
OBJECTIVES Toll-like receptors (TLRs) detect microbial infections and they can directly induce innate host defense responses. TLR 2 has been shown to be primarily involved in the recognition of peptidoglycans and lipoteichoic acid of gram positive bacteria. TLR 4 recognizes lipopolysaccharides and lipoteichoic acids from both gram-negative and gram-positive(More)
IMPORTANCE Several trials on the predictors of response to proton pump inhibitor (PPI) treatment of laryngopharyngeal reflux (LPR) have shown conflicting results. Furthermore, the influence of age in disease severity and response to PPI therapy is unclear. OBJECTIVE To assess the difference in disease severity and response to PPI therapy according to age(More)
This study was designed to evaluate the prognostic value of circumferential resection margin (CRM) in rectal cancer patients who underwent curative resection with adjuvant chemoradiotherapy (CRT). We studied 504 patients who underwent total mesorectal excision with adjuvant CRT for rectal cancer between 1997 and 2001. The patients were divided into two(More)
OBJECTIVE To analyze patterns of central lymph node (LN) metastasis to specific compartments in the neck and predictive factors of contralateral paratracheal LN metastasis in patients who underwent prophylactic bilateral central LN dissection for papillary thyroid cancer (PTC). STUDY DESIGN Prospective study. SETTING Multitertiary centers. SUBJECTS(More)
