Background: A professional vision at education is necessary, because of the increasing development of technical education in the field of medical education. In the conventional methods, although mastering in the field and being up-to-date is necessary, today, the faculty member must be able to design and implement a group of learning experiences for the students in order to learn and to conduct valid exams.
Methods: Our study was an interventional study, conducted on obstetrics and gynecology residents of the 3rd and 4th year at Tehran University of Medical Sciences in March, 2016. The number of participants was 66. The data collection was performed by a questionnaire. The included 19 questions about the anatomy of pelvic floor. At first, the questionnaires were administered to pre-test students to assess the amount of information before and then the theoretical and practical class about the anatomy of pelvic floor were held. At the end of classes, pre-test questionnaires were returned to residents. The responses to questions before and after the training were analyzed.
Results: Our study was conducted on 66 obstetrics and gynecology residents. Of the 66 subjects, 30 were in the pre-test and 66 were in the post-test. The mean score of residences in the anatomy of the pelvic floor before intervention was 5.388±7.14 and after intervention was 12.57±2.181 (P=0.001). The difference in mean before and after education was significant at all levels of study. The general knowledge scores in the post-test, was significantly (P<0.05) higher than pre-test.
Conclusion: According to our findings, it can be stated that the implementation of scholarship project regarding the knowledge of obstetrics and gynecology residences by the method of theoretical and anatomical teaching of anatomy of pelvic floor increases their knowledge, consequently, increase ability of surgical procedures of the residents and reduce complications. It is recommended that other education centers use a similar method to educate obstetrics and gynecology residents.

Background: Short children face many problems throughout their lives. Consumption of growth hormone and the drugs such as Letrozole, Oxandrolone, and Anastrozole can increase the growth of children and adolescents. There is not an overall estimate of the effects of Letrozole, Oxandrolone, and Anastrozole on the growth of children and adolescents with Idiopathic Short Stature (ISS). There are different estimates of the effect of growth hormone and the drugs Letrozole, Oxandrolone, and Anastrozole on growth in children and adolescents with Idiopathic Short Stature. Therefore, the aim of this study was to compare the efficacy of growth hormone, Letrozole, Oxandrolone, Anastrozole, and a combination of growth hormone and aromatase inhibitors on height gain in children and adolescents with idiopathic short stature using meta-analysis method.
Methods: Search was done in databases such as; Scopus, Web of Science(ISI), and PubMed using keywords: Idiopathic, Short Stature, Body Height, Aromatase Inhibitors, Growth hormone, Letrozole, Oxandrolone, Anastrozole. Randomized clinical trial studies ,that have investigated the efficacy of growth hormone and aromatase inhibitors on height gain in children and adolescents with short stature, were selected. Height standard deviation score (HSDS) before intervention and after treatment has been used to measure the rate of height increase in various studies. This study was written based on the PRISMA checklist and the heterogeneity of this study was evaluated using the Q statistic and I² index.
