introduction: the conventional method of teaching endodontics has some drawbacks. due to the small size of the oral cavity, students cannot closely observe the clinical procedure. use of new teaching modalities such as the intraoral camera may obviate this problem. this study assessed the effect of video-assisted clinical instruction in dentistry (vacid) on dental student’s knowledge and perfor...

introduction: the treatment of complicated parapneumonic effusion (ppe) and thoracic empyema (te) is controversial; and the choice of treatment after confirming the failure of simple drainage remains unclear. the purpose of this study was to compare the outcomes of intrapleural urokinase (uk) administration and video-assisted thoracoscopic surgery (vats) as initial treatment options for ppe and...

Online video lectures have been considered an instructional media for various pedagogic approaches, such as the flipped classroom and open online courses. In comparison to other instructional media, online video affords the opportunity for recording student clickstream patterns within a video lecture. Video analytics within lecture videos may provide insights into student learning performance a...

Video-assisted thoracoscopic surgery is finding an ever-increasing role in the diagnosis and treatment of a wide range of thoracic disorders that previously required sternotomy or open thoracotomy. The potential advantages of video-assisted thoracoscopic surgery include less postoperative pain, fewer operative complications, shortened hospital stay and reduced costs. The following review examin...

BACKGROUND AND OBJECTIVES Video-assisted thoracoscopy has been successfully used for several different thoracic procedures in adults. However, its use in children has been limited. The present study evaluated our experience with video-assisted thoracoscopy in the diagnosis of mediastinal masses in children. METHODS Nine children (age range, 3 to 18 years) with undiagnosed mediastinal masses u...

Introduction: The treatment of complicated parapneumonic effusion (PPE) and thoracic empyema (TE) is controversial; and the choice of treatment after confirming the failure of simple drainage remains unclear. The purpose of this study was to compare the outcomes of intrapleural urokinase (UK) administration and video-assisted thoracoscopic surgery (VATS) as initial treatment options for PPE and...

INTRODUCTION Cost analysis studies performed in western countries report that the overall cost of lobectomies performed via video-assisted thoracic surgery is similar to or less than those performed via thoracotomy. The situation may be different in a developing country. AIM We evaluated the cost differences of these two surgical methods. MATERIAL AND METHODS We retrospectively reviewed the...

BACKGROUND AND OBJECTIVE: Video-assisted thoracoscopic surgery is preferred over conventional methods, such as pleural biopsy, in the diagnosis and treatment of patients with pleural effusion. Considering that Imam Khomeini Hospital is facing a large volume of patients with pleural effusion of unknown origin referred from other centers, the present study was conducted to investigate the role of...
