The Role of the Flipped Classroom Method in Short-Term and Long-Term Retention Among Undergraduate Medical Students of Anatomy.

Introduction Medical education is changing towards more flexible, effective, active, and student-centred teaching strategies that reduce the limitations of traditional methods of education. Recently, the flipped classroom method has been suggested to support this transition. However, research on the use of flipped classroom methods in medical education pertaining to short- and long-term retention of the topics is at an early stage. The present paper aims to determine and compare the effects of traditional and flipped classroom methods on first-year medical students' short-term and long-term retention. Method Fifty first-year medical students were subjected to traditional and flipped classroom modules in the form of five sessions each on gross anatomy topics of the thoracic region. These sessions were conducted during independent teaching slots for anatomy. Assessments were done at the completion of each module for both methods. Then, after a gap of two months, the students were again assessed on the content taught in the modules as a part of formative assessment. The data so obtained were compared and analysed statistically. Ethical approval was obtained prior to beginning the study. Written informed consent was obtained from the participating students. Result A total of 50 first-year medical students participated in the study. 33 (67%) participants were males, with a median age of 19.47 years, and 17 (33%) participants were females, with a median age of 19.39 years. The assessment scores showed differences between the two methods of teaching in the short and long term. The flipped classroom method was observed to have significant short-term retention with a p-value <0.0001, which is statistically significant. Conclusion The study concludes that the flipped classroom method serves as an advantageous tool and motivating factor for effective learning, understanding, and retention of conceptual and factual anatomical content.

SXP-RAL Family Filarial Protein, rWbL2, Prevents Development of DSS-Induced Acute Ulcerative Colitis.

Helminthic infections lead to the release of various molecules which play an important role in modulation of the host immune system. Such filarial proteins with immunomodulatory potential can be used for therapeutic purpose in inflammatory and immune mediated diseases. In the present study, we have explored the prophylactic effect of filarial SXP-RAL family protein of Wuchereria bancrofti i.e. rWbL2 protein in DSS induced inflammatory ulcerative colitis in a mouse model. Prior treatment of rWbL2, followed by induction of colitis, showed significantly reduced disease severity as indicated by the decreased disease manifestations and improved macroscopic and microscopic inflammation. This preventive effect was found to be associated with increased release of anti-inflammatory cytokine IL-10 and decreased release of proinflammatory cytokines IFN-γ, TNF-α, IL-6 and IL-17 by the splenocytes of treated mice. From this study, it can be envisaged that pretreatment with filarial protein, rWbL2, can prevent the establishment of ulcerative colitis in BALB/c mice. The underlying immunological mechanism may involve the up-regulation of Th2 immune response with down-regulation of Th1 response.

Histomorphometric demonstration of the effect of chronic use of nonsteroidal anti-inflammatory drugs-ibuprofen on mucosa of small intestine.

The purpose of this study was to ascertain change in structure of mucosa of small intestine, if any, in small intestine of Swiss albino mice as an effect of chronic use of nonsteroidal anti-inflammatory drugs-Ibuprofen. Longitudinal study conducted on 46 adult Swiss albino mice, 23 as experimental and 23 as control. Ibuprofen was given at a dose of 40 µg/g body weight per day for 6 weeks by intragastric route in experimental group of mice while control group of mice received same volume of distilled water. Mice of both the groups were sacrificed and desired segments of small intestines were dissected out and tissues were subjected to histological processing. Histomorphometry was performed and relevant photomicrographs were obtained. Student's unpaired t test by GraphPad Prism 6 software. Height of villi was not significantly altered but there was significant reduction of the number of goblet and non-goblet cells (enterocytes and other columnar cells) in mucosal lining of the small intestine of experimental group of mice. Percent distribution of the goblet and non-goblet cells was not altered in villi of two groups. Chronic exposure of Ibuprofen in therapeutic dosage caused reduction of the functional cell mass in lining epithelium of villi of middle segment of small intestine. However, there was no evidence of ulcerative or hemorrhagic lesion.

Dermatoglyphics and karyotype analysis in primary amenorrhoea.

BACKGROUND: Dermatoglyphics is the scientific study of the skin ridge patterns on the fingers, toes, palms of the hands and soles of feet. Dermatoglyphics is in use as a supportive diagnostic tool in genetic or chromosomal disorders as well as in clinical conditions with genetic etiologies. Primary amenorrhoea and Dermatoglyphics, both have the suspected multifactorial (genetic and environmental) aetiologies. OBJECTIVE: In the present study the finger dermatoglyphic patterns were studied in primary amenorrhoea cases and age matched fertile control females and also attention was given to find out whether a specific dermatoglyphic trait exists in primary amenorrhoea cases and whether it was statistically significant. MATERIALS AND METHODS: To study the role of dermatoglyphics in primary amenorrhoea, a study was conducted on 30 subjects with primary amenorrhoea (as cases) and compared it with equal number of age matched fertile females (as controls). We studied fingertip patterns in all the subjects enrolled. Simultaneously we have assessed the Karyotype of primary amenorrhoea cases. RESULT AND CONCLUSION: Two subjects in experimental group have shown abnormal Karyotypes. The most significant finding in present study was increased total finger ridge count (TFRC) in primary amenorrhoea cases which was statistically significant. We also found higher frequency of loops and arches in primary amenorrhoea with abnormal karyotypes. This type of study may be quite useful as a supportive investigation, in stating the predisposition of an individual to primary amenorrhoea and referral of an individual for karyotyping.
