Perceptions and preferences of medical students regarding teaching methods in a Medical College, Mangalore India

Introduction: In the complex setting of a medical school it becomes essential to utilize an approach to teaching and learning that is best suited to the needs of the students. In developing countries like India, where there is an exponential increase of institutions catering to medical students, it becomes a challenge to teach to large number of students per class. Hence, research is needed to identify the needs of students in relation to their day to day learning activities.Objectives: To understand the preferences and perception of medical students about the current methods of teaching, aids used for teaching and also identify barriers in learning as perceived by the students.Method: A Cross-sectional study was carried out at Kasturba Medical College, Mangalore during May 2012. Study participants included 2nd and 3rd year medical students. A semi-structured questionnaire was used to collect the information in relation to preferences and perceptions regarding teaching methods utilized for theory and clinical teaching. SPSS version 11.5 was used for analysis of data. The association between variables of interest was tested using Chi-square test.Results: A total of 286 students (56.6 % females and 43.4% males) participated with a dropout rate of 10.6%. The study revealed that 71.3% of the students had an attendance above 75%. The most preferred teaching method was Problem Based Learning (PBL) (71.4%) as students felt that it enhanced lateral thinking while Didactic Lectures was the least preferred (32.8%). The most preferred modality of teaching aid was found to be Black board preferred by 46.9% students. In learning rare signs and cases, students preferred video lectures (41%) and mannequins (75.9%) in learning clinical skills. The main barrier in theory learning identified was inappropriate teaching methods (15%) and being new to clinical posting (38.5%) in case of learning clinical skills.Conclusion: The findings of the study suggest that a combination of traditional methods with other methods such as PBL, video lectures and mannequins could be an effective way of teaching theory and clinical skills.Keywords: Perceptions and preferences, teaching methods, medical students, Indi

Proctitis following stereotactic body radiation therapy for prostate cancer

Background Proctitis after radiation therapy for prostate cancer remains an ongoing clinical challenge and critical quality of life issue. SBRT could minimize rectal toxicity by reducing the volume of rectum receiving high radiation doses and offers the potential radiobiologic benefits of hypofractionation. This study sought to evaluate the incidence and severity of proctitis following SBRT for prostate cancer. Methods Between February 2008 and July 2011, 269 men with clinically localized prostate cancer were treated definitively with SBRT monotherapy at Georgetown University Hospital. All patients were treated to 35-36.25Gy in 5 fractions delivered with the CyberKnife Radiosurgical System (Accuray). Rectal bleeding was recorded and scored using the CTCAE v.4. Telangiectasias were graded using the Vienna Rectoscopy Score (VRS). Proctitis was assessed via the Bowel domain of the Expanded Prostate Index Composite (EPIC)-26 at baseline and at 1, 3, 6, 9, 12, 18 and 24 months post-SBRT. Results The median age was 69 years with a median prostate volume of 39 cc. The median follow-up was 3.9 years with a minimum follow-up of two years. The 2-year actuarial incidence of late rectal bleeding ≥ grade 2 was 1.5%. Endoscopy revealed VRS Grade 2 rectal telangiectasias in 11% of patients. All proctitis symptoms increased at one month post-SBRT but returned to near-baseline with longer follow-up. The most bothersome symptoms were bowel urgency and frequency. At one month post-SBRT, 11.2% and 8.5% of patients reported a moderate to big problem with bowel urgency and frequency, respectively. The EPIC bowel summary scores declined transiently at 1 month and experienced a second, more protracted decline between 6 months and 18 months before returning to near-baseline at two years post-SBRT. Prior to treatment, 4.1% of men felt their bowel function was a moderate to big problem which increased to 11.5% one month post-SBRT but returned to near-baseline at two years post-SBRT. Conclusions In this single institution cohort, the rate and severity of proctitis observed following SBRT is low. QOL decreased on follow-up; however, our results compare favorably to those reported for patients treated with alternative radiation modalities. Future prospective randomized studies are needed to confirm these observations
