RESUMO
Background: A right concept has to be obtained to the medical student’s during their under-graduation periodbecause knowledge of Anatomy forms the basic foundation for most of clinical subjects like Medicine, Surgery,OBG, ENT, Ophthalmology, Orthopedics, Radiology and Neurology. So, we professors need to give a clear tridimensional familiarity of human body using best teaching methodology. In medical education technology, thereis a swift change from Blackboard to virtual simulations and other teaching methodologies. So we have takenfeedback from the students so that the best teaching aid and method can be adopted to improve their academicperformance. The study was designed to know the preferred one amongst teaching aids like traditional chalk &board versus Power Point Presentation among the 1st Year MBBS students.Methods: For a period of 3 years150 MBBS students of 2016-17 batch from Malla Reddy Institute of medicalsciences, Suraram, 2017-2018 batch of Maheshwara Medical College and Hospital, Chitkul village, Patancheru,and 2019-20 batch from Mamata Academy of Medical sciences, Bachupally of Telangana state were selectedand delivered Anatomy lectures for a period of 3 months. The questionnaire was prepared covering the differentaspects of the lecture and was asked to voluntarily go through the questionnaire and evaluate their preferencesafter each class.Results: Out of 450 students of 3 consecutive years Blackboard was preferred by 139 students, 90 studentspreferred PowerPoint Presentation and 183 students preferred both the teaching methods and 38 students wereabsent totally.Conclusion: By using and adopting the best teaching aids the teacher can improve the academic performance ofthe students. Thus, there is a scope for improvisation in medical education and forming a strong basic foundationfor medical graduates
RESUMO
Objective: To compare the effectiveness of preoperative subconjunctival injection of Mitomycin-C at 24-hour and at one month before primary pterygium excision
Study Design: Randomised controlled trial
Place and Duration of Study: Eye Department, Combined Military Hospital, Sargodha, from January to December 2014
Methodology: Eyes of 60 patients were randomly allocated into two equal groups [A and B] of 30 each. In group A Mitomycin-C was injected into the pterygium one month before, and in group B Mitomycin-C was injected 24 hours before excision. All pterygia received 0.1 ml of Mitomycin-C in a concentration of 0.15 mg/ml. Primary pterygia greater or equal to 2.5 mm were selected and excised as a bare sclera technique. Postoperatively, all patients were followed-up for 06 months. The recurrence and corneoscleral complications were recorded. Pearson chi-square test was used to compare the recurrence between group A and group B
Results: The recurrence of pterygium in group A was 3.3%; and in group B, it was 6.7%. Comparison of the recurrences between both the groups was statistically insignificant, [p=0.554].Postoperatively, no serious corneoscleral complications occurred in either group
Conclusion: The preoperative subconjunctival injection of Mitomycin-C in a dose of 0.15 mg/ml given 24 hours prior to excision is as effective as 01 month preoperative injection for primary pterygium surgery with bare sclera technique
