p57 (Kip2) belongs to the Cip/Kip family and is one of the universal negative regulators of the cell cycle. In this study, we investigated the p57 expression of various types of thyroid neoplasm. p57 overexpression was observed in only 4.2% of normal thyroid tissues. In follicular adenoma and minimally invasive follicular carcinoma, p57 was overexpressed in 100% and 91.7% of the cases, respectively. However, its incidence was significantly lower (p<0.0001) in widely invasive follicular carcinoma, of which only 36.4% overexpressed p57. This phenomenon was seen in 63.1% of papillary carcinoma and 13.3% of anaplastic (undifferentiated) carcinoma. Furthermore, poorly differentiated and undifferentiated carcinoma more frequently lacked p57 expression (p<0.0001). These results suggest that the down-regulation of p57 may play a role in the dedifferentiation of thyroid carcinoma and in follicular carcinoma mutating to be more invasive.

This study aimed to determine the incidence of traumatic dental injuries (TDIs) during oral tracheal intubation by traditional laryngoscopy in general anesthesia (GA) in pediatric patients aged 4-13 and the correlated risk factors in Damascus, Syria. The study included children at the Department of General Surgery, Damascus University. Each child was examined before, during, and after 12-24 h of entering the operation room.

Objective: Successful embryo implantation is contingent upon the intricate interaction between the endometrium and the blastocyst. Recurrent implantation failure (RIF) signifies the clinical challenge of failing pregnancy post-transfer of high-quality embryos, fresh or frozen, in at least three in vitro fertilization (IVF) cycles, often in women under 40 years. Recent studies identify impaired blastocyst maternal tissue communication among recurrent implantation failure causes.

Purposes: We analyzed the acute-phase response in unilateral thyroidectomy by comparing the transoral endoscopic thyroidectomy vestibular approach (TOEVA) with the minimally invasive video-assisted thyroidectomy (MIVAT).
Methods: Patients were randomly assigned to undergo either TOEVA or MIVAT, after we obtained their written informed consent to participate in this study. Blood count, C-reactive protein (CRP), erythrocyte sedimentation rate (ESR), interleukin-1β (IL-1β), IL-6 and tumor necrosis factor (TNF-) were measured before surgery and then 4, 24, and 48 h after surgery.

Thyroid cancer is a common malignancy that requires comprehensive clinical evaluation prior to adequate surgical management. Over the last three decades thyroid surgery has tripled and is considered one of the most commonly performed procedures in general surgery. These procedures are associated with potential postoperative complications with significant deterioration in the patient's quality of life.

While ultrasonography effectively diagnoses Hashimoto's thyroiditis (HT), exploring its transcriptomic landscape could reveal valuable insights into disease mechanisms. This study aimed to identify HT-associated RNA signatures and investigate their potential for enhanced molecular characterization. Samples comprising 31 HT patients and 30 healthy controls underwent RNA sequencing of peripheral blood.
