This descriptive type of cross sectional study was conducted to determine the learning styles of undergraduate medical students. The study period was from July 2017 to June 2018. The study was carried out among the students of 2nd, 3rd and 4th phases of MBBS course of 3 government and 4 non-government medical colleges of Bangladesh. Out of 7 medical colleges, 4 were within Dhaka and 3 were from outside Dhaka. The sample size was 1004 students. Medical colleges were selected purposively and convenience sampling technique was adopted for data collection. Bangla translated version Fleming's VARK (visual, auditory, read/write and kinesthetic) questionnaire was used to identify the learning styles of students. The study revealed that out of 1004 medical students, 64.2% preferred multimodal learning styles and rest 35.8% preferred unimodal learning styles. Among unimodal learning preferences, auditory (A) and kinesthetic (K) were the most preferred sensory modalities of learning. Among multimodal learning styles preferences, the combination of auditory & kinesthetic (AK) and auditory, read/write & kinesthetic (ARK) were predominant. There were only significant differences of the mean scores of visual (V) learning style among the male and female students. Majority of students preferred multimodal learning styles. Students are able to learn effectively as long as the teacher provides a blend of visual, auditory, read/writing and kinesthetic activates. The study recommended that teachers should be aware of the medical students' learning styles and aligning teaching-learning methods with learning styles will improve their learning and academic performance.

This study set out to identify the institutional difficulties encountered by the undergraduate medical students of Bangladesh. This was a descriptive type of cross sectional study, conducted from July 2017 to June 2018. The population of the study consisted of undergraduate medical students and medical teachers of 8 medical colleges of Bangladesh including both government and non-government which were located in Dhaka and outside of the Dhaka. Medical colleges and medical teachers were selected purposively and students were selected by the convenience sampling technique. The questionnaire using five points Likert scale were administered on 1059 medical students and in-depth interviews were conducted with 13 medical teachers. The study revealed that most of the students faced institutional related difficulties, particularly cleanliness of campus 480 (45.6%), unclean toilet 762 (72%), poor quality canteen 663 (63%), poor games facilities 792 (75%), insufficient hostel accommodation 669 (65.2%), unclean hostel 652 (63.5%), insufficient recreation facilities in hostel 702 (68.5%) and irregular hostel supervision by the authority 590 (57.6%). Based on the study, it was suggested that concerned authority should consider the findings and should take some significant steps for sustainable solutions to the difficulties of the students.

Background: Diagnostic validity of different tests for the detection of spontaneous subarachnoid haemorrhage is an important issue. Objectives: The purpose of the present study was to validate 3D-Computed tomographic angiography in spontaneous subarachnoid haemorrhage. Methodology: This cross-sectional study was carried out in the Department of Neurosurgery and Cath Lab of DMCH in collaboration with private diagnostic centre from September 2013 to February 2015 for a period of six (06) months. Adult patients diagnosed as a case of spontaneous SAH based on clinical features and confirmed by plain CT evidence of subarachnoid blood were included as study population. Patients having current history of trauma, poor clinical grade and agitated patient, patient with renal insufficiency, known allergy to iodinated contrast agent and patients who were not willing participate in the study were excluded from this study. Then both CT angiography and DSA were performed to detect cause of bleeding and to make a treatment planning. In this study DSA was considered as reference standard for evaluation of CTA. Sensitivity, specificity, positive predictive value, negative predictive value and diagnostic accuracy of CTA were calculated per patient basis and per aneurysmal basis. Result: A total number of 37 patients presented with spontaneous subarachnoid haemorrhage were recruited for this study. The mean age of patients was 58.53±7.54 years. Sensitivity and specificity in depicting intracranial aneurysms were, 93.75% and 100% respectively on a per-patient basis. Positive predictive value and negative predictive value of CTA are 100% and 71.43% respectively. CTA had shown 94.59% accuracy in detection of intracranial aneurysm. Sensitivity and specificity in depicting intracranial aneurysms were 94.74% and 100% respectively on a per-aneurysm basis. Positive predictive value and negative predictive value of CTA are 100% and 71.43% respectively. CTA had shown 95.35% accuracy in detection of intracranial aneurysm. Conclusion: In conclusion CTA has high detection capacity of aneurysm among spontaneous subarachnoid haemorrhage patients. Journal of National Institute of Neurosciences Bangladesh, 2019;5(1): 47-52
