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)
The biomechanical interaction between the leg stump and the prosthetic socket is critical in achieving close-to-normal ambulation. Although many investigations have been performed to understand the biomechanics of trans-tibial sockets, few studies have measured the socket interface pressure for transfemoral amputees. Furthermore, no report has examined how(More)
OBJECTIVES The purpose of this study was to evaluate diagnostic performance of histogram analysis using grayscale ultrasound (US) images in the diagnosis of lymphocytic thyroiditis. METHODS Three radiologists reviewed a total of 505 US images and classified the images according to the presence/existence of lymphocytic thyroiditis. After 2 months, each(More)
Patients with early gastric cancer (EGC) who have undergone noncurative endoscopic resection (ER) generally require additional surgery due to the possibility of lymph node metastasis (LNM). This study aimed to develop a reliable risk-stratification system to predict LNM after noncurative ER for EGC. A total of 2368 patients had a diagnosis of EGC and(More)
A lateral position (LP) during sleep is effective in reducing sleep disorder symptoms in mild or moderate sleep apnea patients. However, the effect of head and shoulder posture in LP on reducing sleep disorders has not been reported. In this study, effective sleeping positions and a combination of sleep position determinants were evaluated with respect to(More)
Intraperitoneal insufflation of carbon dioxide may affect the sympathetic activity that leads to changes in ventricular repolarization. This in turn can result in changes of heart rate-corrected QT (QTc) interval and Tpeak–Tend (Tp-e) interval. Dexmedetomidine is a highly selective a2-receptor agonist and has potential antiarrhythmic properties. This(More)
PURPOSE We evaluated the ratio of delta neutrophil index (DNI) to albumin (A) in patients receiving early goal-directed therapy (EGDT) to determine the prognostic significance of the DNI/A ratio as a marker of early mortality in critically ill patients with suspected sepsis. METHODS We retrospectively analyzed records from a prospective EGDT registry in(More)
The objective of the study was to evaluate whether texture analysis using histogram and gray level co-occurrence matrix (GLCM) parameters can help clinicians diagnose lymphocytic thyroiditis (LT) and differentiate LT according to pathologic grade. The background thyroid pathology of 441 patients was classified into no evidence of LT, chronic LT (CLT), and(More)
Diabetic foot ulcer is the most common cause of diabetes-associated nontraumatic lower extremity amputation. Most patients who undergo lower extremity amputation for a diabetic foot have had diabetes for a long time and suffer from multiorgan disorder; thus, it can be a challenge to ensure sufficient anesthetic and analgesic effects while maintaining stable(More)
We investigated whether follow-up ultrasound (US) is enough for thyroid nodules 5-10 mm, and whether 3 years of interval between the initial US and next US is appropriate. This retrospective study was approved by the Institutional Review Board, and the need to obtain informed consent was waived. The study included 447 thyroid nodules 5-10 mm from 378(More)
