OBJECTIVES In recent years, BRAF(V600E) mutation has emerged as a promising prognostic marker for risk stratification of patients with papillary thyroid carcinoma (PTC). However, routine use of this marker has been questioned. In some parts of the world, particularly in Korea, the incidence of BRAF(V600E) mutation is too high to have true prognostic value.(More)
BACKGROUND Pathologically confirmed microscopic extrathyroidal extension (ETE) is often identified after hemithyroidectomy in patients with papillary thyroid microcarcinoma (PTMC). Without the presence of microscopic ETE, these patients would be optimal candidates for hemithyroidectomy. AIM The present study aimed at evaluating the clinical impact of(More)
OBJECTIVES Numerous studies have reported the effects of subclinical hyperthyroidism on the cardiovascular system, osteoporosis, and metabolic syndrome. However, there are few studies examining the relationships between subclinical hyperthyroidism and thyroid cancer. The aim of this study was to investigate the relationships between preoperative subclinical(More)
BACKGROUND The relationship between Hashimoto's thyroiditis (HT) and papillary thyroid cancer (PTC) with regard to their co-occurrence and the effect of concurrent HT on the prognosis of PTC has been debated. The aim of the present study is to determine a clinical relationship between these two disease entities and to evaluate the correlation between(More)
To test the hypothesis that insulin regulates leptin, we measured the plasma leptin concentration before and during treatment of diabetic ketoacidosis (DKA), a condition characterized by extreme insulin deficiency. The study included 17 patients with type 1 diabetes (7 males and 10 females), aged 10+/-1 yr (mean +/- SE), with a body mass index of 17.6+/-1.9(More)
BACKGROUND Chyle fistula is a relatively rare complication of neck dissection, and there is a lack of consensus regarding its incidence, risk factors, and management. METHODS Between 2007 and 2014, a total of 472 cases of neck dissection involving the level IV compartment were included in the study. The incidence, risk factors, and clinical course of(More)
Although a foreign body ingestion is common in infants and young children, serious complication such as penetration of the esophagus is a relatively rare event. Delayed diagnosis may result from lack of classical symptoms and history, leading to serious result, even to death. A 2-year-old boy was admitted to the emergency room with dyspnea. He had wheezing(More)
OBJECTIVES We compared the complications and diagnostic adequacy of ultrasound (US)-guided core needle biopsy (CNB) for head and neck mass lesions between patients who did and did not receive antiplatelet/anticoagulation therapy. METHODS This study was designed as a prospective case study including 146 consecutive patients who underwent US-guided CNB for(More)
OBJECTIVE To review our 15-year experience with pyriform sinus fistula (PSF) in a single institution for a better understanding of the disease, pertaining especially to symptom onset at different ages. METHODS Medical records were reviewed for all 21 PSF patients presenting between 1998 and 2012. Patients were then divided into pediatric (≤ 15 years old)(More)
