Interactive Quiz-Based Anatomy Teaching for Medical Undergraduate Students.

BACKGROUND: Anatomy is one of the most volatile subjects and needs the learner to understand and retain a lot of information and terms. It is thus very important to continuously upgrade the methodology from the traditional didactive to interactive teaching to make the student an active learner and engage him in the learning process to categorize and analyze anatomical facts and knowledge. AIMS AND OBJECTIVES: The study was done to compare the learning outcomes and perception of medical students towards didactic lectures and interactive quiz-based lectures in anatomy. METHODOLOGY: The study was conducted amongst the 200 Year 1 medical undergraduate students enrolled in the Department of Anatomy at Dr. Ram Manohar Lohia Institute of Medical Sciences, located in Lucknow, India. The 200 students comprised 120 males (60%) and 80 females (40%). The mean age of male students was 19.67 years and of females was 19.52 years. The students were divided into two groups of hundred students each by a method of convenience sampling. Students of group I were taught by an interactive quiz-based lecture and group II by a traditional didactic lecture. A pre- and post-test were conducted for both groups and feedback for both methods was taken by using a pre-validated feedback form based on a 5-point Likert scale. RESULTS: On statistical analysis, it was found that in the post-test the performance of group I taught by the interactive quiz-based study was better as compared to group II taught by traditional didactive teaching, but was not statistically significant (p=0.233, p>0.05). The feedback from students revealed that 45.9% of them strongly agreed and 44.9% agreed with the fact that quiz-based lectures are better than routine lectures. CONCLUSIONS: Results of the present study clearly indicate that the introduction of quiz-based anatomy teaching for undergraduate medical students was well received and appeared to improve their learning outcomes in the form of increased attention and participation during class and would lead to better retention of the topics taught during interactive lectures. To the best of our knowledge, no previous study has been done to document the efficacy of quiz-based teaching for the subject of anatomy.

Gross Anatomy Teaching for Medical Undergraduates Through Computer-Based Simulation: Introduction and Evaluation of Effectiveness.

Background Cadaveric teaching has been the gold standard for gross anatomy instruction through the ages and across the geographic spectrum, but with issues of availability faced in many medical schools, there is a need to look for other options. Digital tools like virtual dissectors that simulate the cadaver have been around for some years now, but their acceptability to the teachers and students and effectiveness need to be validated in the settings where applied. Aim To evaluate the acceptability, feasibility and effectiveness of using computer-based simulation tools for teaching gross anatomy via online mode to undergraduate medical students. Methodology A prospective crossover randomized controlled study was conducted online on 200 (120 males (60%) and 80 females (40%), Year 1 medical undergraduates (mean age males: 19.67 years and females: 19.52 years), wherein two broad topics of head and neck region were taught by didactic lectures delivered online via Zoom. Dissection videos were prepared for both cadaveric and computer-based simulation teaching. Groups were divided by random allocation and pre- and post-tests and feedback surveys were conducted online. Results A significant increase from pre- to post-test scores was found in both cadaveric and computer-based simulation techniques. However, more change was found in the computer technique as its t-value was more than the cadaveric technique. The feedback from the students was that the computer-based simulation teaching method gave them a good insight into 3D understanding of the human body, increased understanding of relations of body structures and capacity to grasp surface anatomy. Conclusion The study concluded that teaching gross anatomy through computer-based simulation techniques is acceptable to both the students and faculty. The study also concluded that it is an effective and feasible method that can be used to complement cadaveric teaching to revisit areas already dissected and for quick revision.

Assessing the Role of Internal Motivation and Extrinsic Factors on Online Undergraduate Medical Teaching in a Resource-Poor Setting During Covid-19 Pandemic in North India: An Observational Study.

PURPOSE: The unprecedented academic environment brought by the COVID-19 pandemic led to the evolution of online teaching as an ineluctable tool for education and training. To ensure that the undergraduate teaching curriculum does not become another victim of the virus, online teaching was started in most medical schools. The undergraduate students enrolled in our institution hail mostly from rural areas and small townships with limited internet connectivity and accessibility due to poor socioeconomic status. This study highlights the students' perception of and motivation towards online classes in respect to internet connectivity and accessibility during COVID-19 pandemic. Since online teaching is essentially a student-centered learning approach, the motivational level of students plays an important role in making teaching protocols effective. METHODS: A prospective qualitative and quantitative assessment of perceptions of 498 medical undergraduate students from 1st, 2nd and 3rd year of Dr. Ram Manohar Lohia Institute of Medical Sciences, Vibhuti Khand, Gomti Nagar, Lucknow, Uttar Pradesh, India was done using validated online questionnaires and anonymous voluntary feedback during the government-imposed lockdown from March 2020 to November 2020. RESULTS: On evaluation of 260 responses received, it was found that the majority of students were motivated to attend the online classes but external factors like internet connectivity and household environment were affecting their motivation on a daily basis and thus decreasing the motivation levels. Validity of feedback by Cronbach's alpha was 0.907 and Pearson coefficient between internet connectivity and motivation factors was 0.419 (p-value <0.001). CONCLUSION: The extrinsic factors of internet connectivity and household environment hamper the motivation of students to attend online classes; this should be considered as an important factor to enable the desired student-led learning as mandated by competency-based medical education.

Ameloblastic carcinoma of maxilla.

Ameloblastic carcinoma (AC) is a rare malignant lesion with characteristic histologic features and clinical behavior that dictates a more aggressive surgical approach than that of a simple ameloblastoma. The tumor cells resemble the cells seen in ameloblastoma, but they show cytologic atypia. Direct extension of the tumor, lymph node involvement, and metastasis to various sites (frequently the lung) have been reported. Wide local excision is the treatment of choice. Regional lymph node dissection should be considered and performed selectively. Literature shows that radiotherapy and chemotherapy is of limited value for the treatment of AC. A case of AC of maxillary region is presented here. Clinical/histological characteristics of this tumor and current knowledge on the classification of odontogenic malignancies are also discussed.

Osteopetrosis-A rare entity with osteomyelitis.

Osteopetrosis is a rare genetic disorder that causes generalized sclerosis of the bone due to defect in bone resorption and remodeling. Albergs-Schonberg disease or autosomal dominant osteopetrosis type II is a rare form of osteopetrosis. Osteomyelitis is a well-documented complication of osteopetrosis. Any associated dental abnormality may be attributed to the pathological changes in bone remodeling. This case report discusses a case of osteopetrosis with osteomyelitis as a complication in a 8-year-old boy.
