A Simple and Innovative Simulator Model for Sialendoscopy Basket Stone Retrieval Training.

We present a simple and innovative sialendoscopy basket stone retrieval (BSR) simulator model composed mainly of a 1.0-mL insulin syringe with detachable needle whose lumen mimics a dilated salivary duct. Dried Guava seeds are used to imitate small-sized floating sialoliths.

Role of Endogenous Bone Marrow Stem Cells Mobilization in Repair of Damaged Inner Ear in Rats.

Background And Objectives: The utilization of the stem cells is widely used in the last few years in different fields of medicine, either by external transplantation or endogenous mobilization, most of these studies still experimental on animals; few were tried on human as in the spinal cord injury or myocardial infarction. As regard its use in the inner ear, stem cell transplantation was examined in many previous studies, while the mobilization idea is a new method to be experimented in inner ear hair cell regeneration. The present work assessed the possibility of mobilizing endogenous bone marrow derived stem cells (SCs) in rats using granulocyte colony stimulating factor (G-CSF) to induce regeneration and repair to experimentally damaged inner ear hair cells by Amikacin injection.
