Pulmonary hypoplasia(PH) commonly occurs in association with oligohydramnios and other congenital anomalies, especially congenital diaphragmatic hernia (CDH). Pulmonary hypoplasia is an important factor, as persistent pulmonary hypertension, in the prognosis of CDH. In some reports, there is a decrement of pulmonary surfactant in PH accompanying CDH.(More)
BACKGROUND The recent increase in the incidence of thyroid cancer has been mainly attributed to papillary thyroid microcarcinomas (PTMCs), and many studies have suggested conservative strategies for the diagnosis and treatment of PTMC. However, PTMCs may be associated with distant metastasis. This study aimed to evaluate the clinicopathological features and(More)
BACKGROUND Measurement of thyroglobulin (Tg) in the washout fluid of fine-needle aspirates (FNA-Tg) is useful for diagnosis of lymph node (LN) metastasis in papillary thyroid carcinoma (PTC). However, the cutoff value of FNA-Tg in the preoperative state is not defined clearly. This study aimed to evaluate the optimal cutoff value of preoperative FNA-Tg(More)
In order to observe the effects of serum albumin and fibrinogen on biophysical surface properties and the morphology of pulmonary surfactant in vitro, we measured the surface adsorption rate, dynamic minimum and maximum surface tension (min-, max-ST) by Pulsating Bubble Surfactometer, and demonstrated ultrastructures on a series of mixtures with varying(More)
Paraduodenal hernias are a rare congenital malformation, but they are the most common internal hernias. They develop secondary to a failure in midgut rotation, which may lead to small bowel obstruction or other clinical manifestations. The authors recently experienced a case of a left paraduodenal hernia presenting with unusual symptoms of left flank pain(More)
BACKGROUND Known factors related to distant metastases in follicular thyroid carcinoma (FTC) included age, primary tumor size, and invasiveness. Distant metastasis is a main cause of death in FTC patients. Several studies showed that the presence of RAS mutations is also associated with poor clinical outcomes. We analyzed RAS mutations in FTC with distant(More)
BACKGROUND Low serum vitamin D levels have been associated with several autoimmune diseases, but their association with thyroid autoimmunity is unclear. We evaluated the association of serum vitamin D levels with the prevalence of autoimmune thyroid disease (AITD). METHODS Our cross-sectional study included subjects who underwent routine health checkups,(More)
Systemic lupus erythematosus (SLE) is an autoimmune disease characterized by immune complex deposition. We genotyped immunoglobulin allotypes of G1M (f,z), G2M (n+,n-), G3M (b,g) and KM (1,3) in 142 Korean patients with SLE and 200 healthy controls to investigate the role of the allotypes in SLE. The allele frequency of G1M (z) was significantly higher in(More)
Thyroid cancers arising from a thyroglossal duct cyst (TGDC) are rarely reported. No clear consensus exists regarding optimal management. In this light, TGDC carcinomas recently treated at Asan Medical Center, as well as previously reported cases in the literature, were reviewed. There were ten patients who were diagnosed with TGDC carcinoma at our(More)
BACKGROUND The aim of this study was to compare the streamlined liner of the pharynx airway (SLIPA), a new supraglottic airway device (SGA), with the laryngeal mask airway ProSeal (PLMA) during general anesthesia. METHODS Sixty patients were randomly allocated to two groups; a PLMA group (n = 30) or a SLIPA group (n = 30). Ease of use, first insertion(More)
