Novel Approach to Vascular Thymic Tissue Transplantation in Humans: A Case Report.

Background: Vascular thymus transplantation has been explored in animal models but remains untested in humans. Current approaches to congenital athymia involve avascular transplantation of allogeneic thymic tissue, which may delay immune recovery. Building on animal studies, we propose revascularization of thymic tissue in a human model.

Experience of the Implementation of Rapid On-Site Evaluation in Ultrasound-Guided Fine-Needle Aspiration Biopsy of Thyroid Nodules.

Objective: To evaluate the effect of the implementation of the rapid on-site evaluation (ROSE) technique in ultrasound-guided fine-needle aspiration biopsy of thyroid nodules.

Materials And Methods: We conducted an observational and retrospective study approved by the Institutional Ethics Committee as an investigation without risk. Between January 2012 and December 2015, 892 ultrasound-guided fine-needle aspiration biopsy procedures were performed under ultrasound guidance.
