We designed and evaluated an objective structured biostatistics examination (OSBE) on a trial basis to determine whether it was feasible for formative or summative assessment. At Ataturk University, we have a seminar system for curriculum for every cohort of all five years undergraduate education. Each seminar consists of an integrated system for different subjects, every year three to six seminars that meet for six to eight weeks, and at the end of each seminar term we conduct an examination as a formative assessment. In 2010, 201 students took the OSBE, and in 2011, 211 students took the same examination at the end of a seminar that had biostatistics as one module. The examination was conducted in four groups and we examined two groups together. Each group had to complete 5 stations in each row therefore we had two parallel lines with different instructions to be followed, thus we simultaneously examined 10 students in these two parallel lines. The students were invited after the examination to receive feedback from the examiners and provide their reflections. There was a significant (P=0.004) difference between male and female scores in the 2010 students, but no gender difference was found in 2011. The comparison among the parallel lines and among the four groups showed that two groups, A and B, did not show a significant difference (P>0.05) in either class. Nonetheless, among the four groups, there was a significant difference in both 2010 (P=0.001) and 2011 (P=0.001). The inter-rater reliability coefficient was 0.60. Overall, the students were satisfied with the testing method; however, they felt some stress. The overall experience of the OSBE was useful in terms of learning, as well as for assessment.

The primary healthcare system is at a turning point in Saudi Arabia. However, the sustainability of family medicine as the core element of that system is increasingly being called into question because of lack of family physicians. In keeping view this problem; a postgraduate diploma program in family medicine has started in 2008. A validated measure of educational environment i.e., Dundee Ready Education Environment (DREEM) questionnaire consisting of 50 questions having five domains of perception was administered to all 13 trainees of the diploma course at the completion of the program to check their perception about learning evironment. The trainees comprised of 4 males (40%) and 6 females (60%). The overall score showed more positive than negative side (147/200). There is no significant difference (P > 0.05) in the mean scores of five different domains of perception. The subclasses of five domains showed that teaching perceived as positive by 50%, moving towards right direction by 80%, feeling more positive by 50%, positive attitude by 80% and the 70% scored the course as not too bad. The overall high score and positive attitude towards the course assures the better teaching environment. However, there are areas to improve and it requires continuous evaluation.

PURPOSE: No study had been conducted to assess the hospitals' environment for learning purposes in multicenter sites in Saudi Arabia. It aims to evaluate the environment of hospitals for learning purposes of pediatric residents. METHODS: We applied Postgraduate Hospital Educational Environment Measure (PHEEM) to measure the learning environment at six teaching hospitals in the Eastern Region of Saudi Arabia from September to December 2013. RESULTS: The number of respondents was 104 (86.7%) out of 120 residents and 37 females and 67 male residents have responded. The residents' response scored 100 out of 160 maximum score in rating of PHEEM that showed overall learning environment is favorable for training. There were some items in the social support domain suggesting improvements. There was no significant difference between male and female residents. There was a difference among the participant teaching hospitals (p<0.05). CONCLUSION: The result pointed an overall positive rating. Individual item scores suggested that their social life during residency could be uninspiring. They have the low satisfactory level and they feel racism, and sexual discrimination. Therefore, there is still a room for improvement.

STUDY DESIGN: Descriptive cross-sectional study. PURPOSE: To determine the prevalence of lumbar spondylolysis and spondylolisthesis in a general adult population unrelated to lower back pain as evaluated by multidetector computed tomography. OVERVIEW OF LITERATURE: There is a significant paucity of information related to the prevalence of spondylolysis and spondylolisthesis and its degenerative changes in a general adult population unrelated to lower back pain in developing countries. METHODS: A retrospective study was conducted on abdominopelvic computed tomography (CT) scans performed between January 1st 2015 and December 31st 2015 for various clinical indications. Patients with lower back pain, with a history of trauma or road traffic accident, or referred from orthopedic or neurosurgery departments were excluded to avoid any bias. CT scans were reviewed in axial, sagittal, and coronal planes using bone window settings for evaluating spondylolysis and spondylolisthesis. RESULTS: Of 4,348 patients recruited, spondylolysis and spondylolisthesis were identified in 266 (6.1%) and 142 (3.3%) patients, respectively. Age was significantly higher in both spondylolysis and spondylolisthesis patients than in those without spondylolysis and spondylolisthesis (47.19±15.45 vs. 42.5±15.96, p<0.001 and 53.01±15.31 vs. 42.44±15.88, p<0.001, respectively). Gender was significantly associated with spondylolisthesis (p=0.029) but not spondylolysis. Of patients who were >60 years old, both spondylolysis (p=0.018) and spondylolisthesis (p=0.025) were significantly more prevalent in females. CONCLUSIONS: The prevalence of pars interarticularis fracture observed higher with gradual increase in the prevalence with advancing age. In particular, preponderance was significantly higher among older females.

Introduction: Ankle arthrodesis using the Ilizarov technique provides high union rate with the added benefits of early weight-bearing, and the unique advantage of its ability to promote regeneration of soft tissue around the bone, including skin, muscle and neuro-vascular structures, and its versatility to allow correction of the position of the foot by adjusting the frame post-operatively as needed. We describe our experience with this technique and the functional outcomes in our patients. Materials and Methods: This retrospective study was conducted in 20 ankle fusion cases using the Ilizarov method between the years 2007 and 2017. We defined success in treatment by loss of preoperative symptoms and radiological union on plain radiographs of the ankle. Results: Fusion was achieved in all patients (100%). Immediate post-operative ambulation was with full weight bearing (FWB) in 16 (83%) of the participants and non-weight bearing (NWB) in 3 patients (17%). Postprocedure 11 patients (67%) of the participants who were full weight bearing required some form of support for walking for 2-3 weeks. Post-operatively three patients had pin tract infection requiring intravenous antibiotics. Radiological union took range of 6-12 weeks, mean union time was 8 weeks. Only one patient required bone grafting due to bone loss. Average follow-up period was 10-45 months. Conclusion: The Ilizarov technique has a high union rate and leads to general favourable clinical outcome and may be considered for any ankle arthrodesis but is especially useful in complex cases such as for revisions, soft-tissue compromise, infection and in patients with risk for non-union. Early weight bearing is an extra benefit.
