Randomized controlled trials are the gold standard of evidence-based medicine. In the field of plastic surgery, designing these studies is much more challenging than in pharmaceutical medicine. Randomized trials in plastic surgery encompass several road blocks including problems shared with other surgical trials: equipoise, high cost, placebo issues and learning curves following the establishme...

Introduction: Ensuring maximum patient safety as well as a complete surgical experience is of utmost importance in training for plastic surgery. As plastic surgical training relies on resident participation in various procedures, we must guarantee adequate hands-on operative time while maintaining the best possible outcomes for the patient. The effect of resident involvement on the outcomes of ...

BACKGROUND Many international volunteer groups provide free reconstructive plastic surgery for the poor and underserved in developing countries. An essential issue in providing this care is that it meets consistent guidelines for both quality and safety-a topic that has been addressed previously. An equally important consideration is how to provide that care in an ethical manner. No literature ...

INTRODUCTION: During the 2015–2016 academic year, plastic surgery residents accounted for nearly 4.2% of surgical residents and 0.8% of residents overall. While the number of residency programs and allotted residency positions in plastic surgery have been steadily increasing in recent years, little information exists regarding residents who are accepted for plastic surgery residency but never m...

INTRODUCTION The WHO Safer Surgery checklist has become an important component of perioperative safety. Our objective, was to determine the compliance of completing the checklist for paediatric emergency plastic surgery patients at our unit. METHODS An initial baseline was performed with 70 patients over two months at our unit. Following this, we raised awareness at an audit meeting and close...

Objective- Assessment of the lens anterior – posterior (AP) diameter as compared with the eye globe by ultrasonography in rabbit.   Design- Descriptive study.   Animals- 120 male and female rabbits, two months to four years old, and weighting between 300 to 1500gr.   Procedures- 2D ultrasonography of the eyes was performed and AP diameter of the eyes and lens were measured using Sonosite Tit...

Horn antennas can result in good impedance matching between the waveguide and free space due to the gradual increase in the aperture size. In this paper, a novel plasmonic sectoral horn nanoantenna based on using lens in the aperture is proposed. It is investigated that in addition to improvement of the directivity, the reflection coefficient is also reduced using the proper lens structure. The...

purpose: to evaluate the prevalence of contat lens wear among highschool girls and their general knowledge about contact lenses and also to evaluate the specific knowledge of contact lens wearers about the lens. methods: in a cross-sectional study, 1664 students of 22 randomly selected girl highschools were enrolled. a questionaire including questions about wearing contact lens, age of first us...

This case report presents an implant-aided prosthetic treatment in which peri-implant plastic surgery techniques were applied in combination to satisfactorily attain functional aesthetic expectations. Peri-implant plastic surgery enables the successful reconstruction and restoration of the balance between soft and hard tissues and allows the option of implant-aided fixed prosthetic rehabilitation.

PURPOSE To investigate regional differences in Ca(2+) mobilization kinetics in the intact human lens produced by exposure to agonists of tyrosine-kinase and G-protein-coupled receptors and to characterize the major receptor subtypes involved in Ca(2+) signaling in the different regions. METHODS Whole human lenses were placed anterior side down in a plastic chamber and perifused with artificia...
