Background and Objective: Needle stick injuries (NSIs) are a common potential risk for healthcare workers. The aim of this study was to evaluate preventive interventions against needle stick injury incidents among HCWs.   Methods: Seven hospitals in the Iranian Chaharmahal-VA-Bakhtiari Province were surveyed between March 2008 to March 2013. Data of the needle stick injuries of healthcare wor...

INTRODUCTION HIV-infected patients require antiretroviral treatment for life. To improve access to care, CD4 enumeration and viral load tests have been redesigned to be used as point-of-care techniques using finger-stick blood. Accurate CD4 counting in capillary blood requires a free flowing blood drop that is achieved by blade incision. The aim of this study was to assess the attitude of the p...

PURPOSE To retrospectively compare the potential dosimetric advantages of a multichannel vaginal applicator vs. a single channel one in intracavitary vaginal high-dose-rate (HDR) brachytherapy after hysterectomy, and evaluate the dosimetric advantage of fractional re-planning. MATERIAL AND METHODS We randomly selected 12 patients with endometrial carcinoma, who received adjuvant vaginal cuff ...

PURPOSE Historically, treatment of malignant surface lesions has been achieved with linear accelerator based electron beams or superficial x-ray beams. Recent developments in the field of brachytherapy now allow for the treatment of surface lesions with specialized conical applicators placed directly on the lesion. Applicators are available for use with high dose rate (HDR)(192)Ir sources, as w...

Stick-slip friction was observed in articular cartilage under certain loading and sliding conditions and systematically studied. Using the Surface Forces Apparatus, we show that stick-slip friction can induce permanent morphological changes (a change in the roughness indicative of wear/damage) in cartilage surfaces, even under mild loading and sliding conditions. The different load and speed re...
