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.

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.
