Our study focuses on environmental risk assessment of a gas power plant in southern Iran. In this research, after investigating the different activities and processes of the power plant, potential harmful factors were initially identified. Afterwards, the identified risk factors were assessed and classified regarding the severity and probability of occurrence, possibility of recycling, and disp...

INTRODUCTION Failure Mode Effects and Criticalities Analysis (FMECA) represents a prospective method for risk assessment in complex medical practices. Our objective was to describe the application of FMECA approach to intraoperative electron beam radiotherapy (IOERT), delivered using a mobile linear accelerator, for the treatment of early breast cancer as an anticipated boost. MATERIALS AND M...

BACKGROUND The complexity of laparoscopic partial nephrectomy (LPN) has prompted many laparoscopic surgeons to adopt robotic partial nephrectomy (RPN) for the treatment of small renal masses. We assessed the learning curve for an experienced laparoscopic surgeon during the transition from LPN to RPN. METHODS We compared perioperative outcomes of the first 20 patients who underwent RPN to the...

INTRODUCTION For the treatment of renal tumors, minimally invasive nephron-sparing surgery has become increasingly performed due to proven efficiency and excellent functional and oncological outcomes. The introduction of robotics into urologic laparoscopic surgery has allowed surgeons to perform challenging procedures in a reliable and reproducible manner. We present our surgical technique for ...
