BACKGROUND: Several studies report that detection of thyroglobulin (Tg) in fine-needle aspiration (FNA) biopsy washout fluid from lymph nodes identifies recurrences/metastases of differentiated papillary thyroid cancer (DPTC) in the neck with higher sensitivity and specificity than fine-needle aspiration cytology (FNAC). However, the diagnostic FNA-Tg cutoff values have not yet been established. OBJECTIVE: To determine an appropriate diagnostic threshold value for Tg levels in FNA washout fluid

Fine-needle aspiration (FNA) biopsy of thyroid nodules is minimally invasive and safe and is usually performed on an outpatient basis. However, the optimal application of FNA requires not only technical skill but also an awareness of the limitations of the procedure, the indications for its use, the factors that affect the adequacy of the biopsy specimen, and the postprocedural management strategy. Ultrasonographic (US) features that are considered indications for FNA include single and multiple

In non-neurologic critically ill patients, the duration of endotracheal intubation was independently associated with PEA development. Additionally, the duration was positively correlated with dysphagia severity and may be helpful for identifying patients who require a swallowing evaluation after extubation.

In thyroid nodules with eggshell calcifications but no other calcifications, the findings of a peripheral halo and disruption of the eggshell calcifications may be more useful sonographic predictors of malignancy than hypoechogenicity, microlobulated margins, and a taller-than-wide shape.

Recurrence and chemoresistance in colorectal cancer remain important issues for patients treated with conventional therapeutics. Metformin and phenformin, previously used in the treatment of diabetes, have been shown to have anticancer effects in various cancers, including breast, lung and prostate cancers. However, their molecular mechanisms are still unclear. In this study, we examined the effects of these drugs in chemoresistant rectal cancer cell lines. We found that SW837 and SW1463 rectal

BACKGROUND: Botulinum toxin (BTX) has been used cosmetically with good clinical efficacy and tolerable safety. OBJECTIVE: This randomized, double-blind, split-face clinical study aimed to investigate the efficacy and safety of intradermal BTX in patients with rosacea. MATERIALS AND METHODS: Twenty-four participants were enrolled and randomly given intradermal injections of BTX and normal saline in both cheeks. Clinician Erythema Assessment (CEA) score, Global Aesthetic Improvement Scale (GAIS) s

The diagnostic performance of radiologists with respect to the characterization of breast masses as benign or malignant was not significantly improved with sonographic elastography. The area ratio of the lesion had a better diagnostic value in elastography than the elasticity score.

본 연구의 목적은 국내 프로배구 경기장의 서비스스케이프와 지각된가치, 스포츠 관여도 그리고 충성도간의 구조관계를 살펴보는데 있다. 2013~2014시즌 프로배구를 관람한 관중을 모집단으로 선정하여 편의표본추출법으로 총 263부의 설문지가 본 연구에 실질적으로 사용되었다. 자료 분석을 위해 Windows용 SPSS 21.0 Version과 Amos 20.0을 이용하여 빈도분석과 신뢰도 분석, 확인적 요인분석, 상관관계분석, 구조방정식 모형분석, 다집단 분석을 실시하였다. 모든 분석에서 통계적 유의수준은 p<.05로 설정하였으며 연구결과는 다음과 같다. 첫째, 서비스스케이프는 스포츠 관여도에 영향을 미치지 않는 것으로 나타났다. 둘째, 서비스스케이프는 지각된가치에 긍정적인 영향을 미치는 것으로 나타났다. 셋째, 서비스스케이프는 충성도에 긍정적인 영향을 미치는 것으로 나타났다. 넷째, 지각된가치는 스포츠 관여도에 긍정적인 영향을 미치는 것으로 나타났다. 다섯째, 지각된가치는 충성도에 긍정

The presence of malignant-appearing US features was independently associated with recurrence in patients with classic PTC.

Repeat FNAB for nodules showing more than 50% growth in volume is unlikely to result in a diagnosis of malignancy. A positive FNAB result for malignancy is significantly more likely in the presence of suspicious US features.
