Perceptions of faculty towards online teaching for undergraduate medical education: An interview-based qualitative study.

Background The Covid-19 pandemic drastically affected medical education. One consequence was the shift of teaching-learning process to the online mode. This left many teachers unprepared. Our medical education department of a large teaching hospital did a qualitative analysis of the perceptions of the faculty towards this forced change. Methods We conducted in-depth interviews with 10 of the nearly hundred undergraduate faculty of a teaching hospital in southern India, with a strength of 100 students per batch. The participants were chosen by purposive sampling so as to include all phases and seniority levels. Seven categories related to the topic of research were decided. These were given to the participants to then speak freely about. Standard methods for recording and transcribing were followed. Deductive content analysis was done to obtain the emergent themes. Results The faculty had a definite negative perception of online teaching. Lack of interaction, absence of immediate feedback and concerns about attendance were uniformly the biggest issues. Practical and clinical teaching was deemed nearly impossible to be taught online. The positives were the gradual comfort factor with online teaching, and the mental preparation for the long haul with this modality. Conclusion In-depth interview and its qualitative analysis proved useful in getting a deeper understanding of the perceptions of the medical faculty towards online teaching-learning. The negative and positive perceptions thus obtained have proved useful as feedback to the medical education department to suggest changes to improve the online teaching programme.

Fibrin glue versus autologous platelet-rich fibrin - comparison of effectiveness on the cohort of patients with fistula-in-ano undergoing video-assisted anal fistula treatment.

Context: Minimally invasive sphincter preserving procedures like ligation of intersphincteric fistula tract (LIFT) and video-assisted anal fistula treatment (VAAFT) are being increasingly used in the treatment of fistula-in-ano. The addition of adjuncts like fibrin glue has improved the results for VAAFT. Our unit has used platelet-rich fibrin (PRF) as an innovative adjunct for VAAFT. Aims: To compare the effectiveness of two different adjuncts, fibrin glue and autologous PRF, used to fill the treated fistula tracts following VAAFT. Settings and Design: Retrospective observational study on a cohort of patients undergoing VAAFT at a tertiary centre between 2015 and 2020 comparing two adjuncts used with VAAFT procedure. Subjects and Methods: Data of patients who underwent VAAFT for fistula-in-ano were obtained from the hospital database. Group A included patients treated with fibrin as adjunct and PRF as adjunct in Group B. Patients were followed up at 1, 3 and 6 months post-operatively and by a telephonic interview in 2020 to ascertain recent status. All data were entered into an excel sheet. Statistical Analysis Used: Data were analysed using SPSS V20 to test the statistical significance of the difference in the mean healing time between two groups, Mann-Whitney U-test was used and for age, Student's t-test was used. Results: There were 41 patients in Group A and 24 in Group B. There was a significant reduction in recurrence rate in Group B (p = 0.032) and in those patients who had a single internal opening (p = 0.045), single external opening (p = 0.03) and complex tracts (p = 0.033). PRF was cheaper than Fibrin glue. Conclusions: PRF is more effective and economical with lower recurrence rates.

Unscrambling the Influence of Sodium Cation on the Structure, Bioactivity, and Erythrocyte Compatibility of 45S5 Bioactive Glass.

The 45S5 bioglass uttering Class A bioactivity promotes both osteoconduction as well as osteoinduction. Though one of the higher reactive bioactive materials known with structural and physiological influence upon ionic modulation, poor mechanical properties are perceived. The possible solution to overcome the weak stability is to choose material's composition that provides retained bioactivity and improved mechanical stability. Meanwhile, primary burst out of Na+ ions increases the local pH, harms cell life, and acts as a well-known disruptive modifying species that weakens the bioactive glass network, decreasing network connectivity, showing faster degradation and lowering mechanical stability. Therefore, in this study, more detailed systematic exploration on structural influence of sodium monovalent cation and its behavior on physiological environment was genuinely studied and reported that bioactivity of the bioactive glass can be highly achieved even without Na+ ions. The result exhibits benefits of sodium free bioactive glass (denoted as No Na+ BG) over Na+ BG and exhibits improved mechanical stability and also possible degradability, having in-built apatite phase even before immersion in simulated body fluid (SBF). Also, sodium free bioglass proved as a superior candidate for erythrocyte compatibility with rapid clotting tendency on interaction with blood and a promising replacement for 45S5 bioglass in all aspects especially in mechanical stability view, which can withstand more than 5 months in phosphate buffer saline (PBS).

Impact of Pelvic Bone Anatomy on Inguinal Hernia and the Role of Radiological Pelvimetry.

Introduction One of the most prevalent disorders treated by general surgeons is inguinal hernias. Many of the etiological factors that lead to hernia development are unknown. This study looked at the role of pelvic bone anatomy in the development of inguinal hernia. The pubic tubercle's location (as measured by the Radoievitch angle) and its relationship to the formation of inguinal hernia, as well as its function in the pathophysiology of various forms of inguinal hernia, were investigated. Materials and methods From October 2019 to June 2021, a prospective case-control study with 70 individuals over the age of 18 years in each arm was conducted in the Department of General Surgery at our tertiary care institution. Plain digital X-ray radiography of the pelvis, including bilateral hips, was taken in the anteroposterior (AP) view with the patient in the supine position, and the Radoievitch angle and Ami line were measured using suitable measuring instruments. The required information for patients in both groups was tallied and examined in a data sheet. Results Between the case and control groups, there was a statistically significant difference in the mean Radoievitch angles and the mean length of the Ami line (42.46 +/-2.442 degrees vs 40.91 +/-2.547 degrees; p<0.05); (8.54+/-1.059 cm vs 7.27+/-1.034 cm; p<0.05). There was a statistically significant increase in the Radoievitch angle of patients with bilateral hernias compared to unilateral hernias (p-value <0.01), as well as indirect hernias compared to other forms of hernias (p-value <0.05). Conclusion The probability of having an inguinal hernia was higher when the Fruchaud region was increased, as indicated by a larger Radoievitch angle or a longer Ami line. A low-lying pubic tubercle increased the likelihood of bilateral and indirect inguinal hernias. Pelvimetry is an easy test that should be considered on a routine basis and can be applied accurately in all patients. Surgeons can employ pelvimetry to identify patients who are more likely to benefit from non-mesh repairs.

Serum TSH Level as a Simple Efficient Tool to Assess the Risk of Thyroid Malignancy in Euthyroid Patients with Indeterminate Cytology - A Cohort Study.

Context: A significant number of fine-needle aspiration cytology (FNAC) for thyroid nodules is reported as indeterminate. Expensive molecular testing can give a clue to the possibility of malignancy in this group. The effectiveness of serum thyroid-stimulating hormone (TSH) levels as a diagnostic tool in euthyroid patients with indeterminate cytology has not been previously studied, especially in the Indian population. Aims: This study was conducted to evaluate the predictive efficacy of serum TSH in the early diagnosis and treatment of malignancy. Settings and Design: This is a retrospective cross-sectional study on a cohort of patients who presented to our department with complaints of thyroid swelling and underwent thyroidectomy. Methods and Material: Euthyroid patients who underwent thyroid surgery for newly diagnosed thyroid nodules with FNAC reported as indeterminate cytology were included in our study. Based on the histopathological report, the patients were divided into two groups and into quartiles based on TSH values. Statistical Analysis Used: The mean difference in the numerical variables between groups was compared using the independent two-sample 't' test for parametric data and Mann-Whitney 'u' test for non-parametric data. A logistic regression analysis was done with age, sex, TSH level and nodule size as dependant variables and malignancy as the independent variable. Results: There were 211 patients in group A and 93 in group B. Patients with malignancy confirmed on final histopathology showed higher serum TSH levels compared to benign nodules (2.93 ± 1.067 vs 1.73 ± 1.051, P = <0.001). The mean TSH levels of all types of malignant nodules correlated with our test model (>2.185 mIU/L). Conclusions: Serum TSH above 2.185 mIU/mL is a good predictor of malignancy in indeterminate nodules. It is an inexpensive, safe and reliable diagnostic screening test for the risk of malignancy in an indeterminate nodule.

Pilot of a questionnaire study regarding perception of undergraduate medical students towards online classes: Process and perspectives.

BACKGROUND: The COVID-19 pandemic situation has forced a shift in medical education from physical classroom to virtual online teaching. However, students and teachers perceive this differently. It is important to study these perceptions to improve the teaching-learning process, and thus to validate the role of online learning in the country. OBJECTIVE: To document the process of a pilot for a questionnaire-based study regarding perception of undergraduate medical students towards on-going online classes. METHODS: Medical Education Department of a teaching hospital developed a new questionnaire with the primary objective of studying the satisfaction and usefulness of the online classes (e-Learning). Content validity was done. For the pilot work, 10% of the total student strength was targeted. Random purposive sampling from each phase of the undergraduate course was done to choose the participants. The questionnaire was administered via Google Classroom. It was an external, undeclared type of pilot. All the responses were documented and analysed for both changes in the questions as well as for statistical sample size derivation for the main study. RESULTS: Responses from 30 students were analysed for the pilot study. Based on the proportion of the level of satisfaction (23.3%) and usefulness (23.3%) of the on-going online classes observed, and with 20% relative precision and 95% confidence, the minimum sample size for the main study was calculated. The responses revealed the need for minor changes in the questionnaire tool for overall feasibility and achievement of the objectives of the main study. CONCLUSIONS: A pilot study is a necessary component for a research project, especially when it involves the use of a new tool. This paper shows the relevance of the same. The authors intend to convey the importance of documenting the processes of conduct of a pilot study, the issues involved therein, and the steps taken to resolve the same.

Perceptions of undergraduate medical students regarding institutional online teaching-learning programme.

BACKGROUND: Medical education all over the country has been forced to shift to e-learning, mainly online classes. In this scenario, the medical education department (MEU) of a teaching hospital under a deemed university felt the need to study the satisfaction and usefulness of these classes, as perceived by the undergraduate medical students. METHODS: Questionnaire survey was planned. A specially designed questionnaire was created, keeping in mind, the study objectives. It was validated, and a pilot was conducted, for modifications and to calculate sample size. The questionnaire was administered by email as Google Forms. The responses, which included quantitative and qualitative responses, were analysed, and feedback points noted. Percentage level of satisfaction and usefulness was calculated with 95% confidence interval. To test the statistical significance of the association of satisfaction levels amongst students of different Phases, chi square test was used. RESULTS: On a scale scoring for satisfaction, 53.6% scored moderate, 31% high, and 15.4% low satisfaction. 49.8% of the students were less satisfied about attending classes from home; 15.7% felt it was better. 57.1% of the students found the concept of online learning moderately useful, 31.4% found it minimally useful, 11.5%, highly useful. CONCLUSIONS: The undergraduate medical students perceived moderate satisfaction and usefulness with the on-going online classes. They expressed the desire to resume routine physical classes, especially for practicals and clinics. Points of improvement of the online teaching-learning programme were also obtained. This study revealed sufficient feedback to be shared with all stakeholders, regarding improvements in the online classes.

Axillary artery thrombosis resulting in upper limb amputation as a COVID-19 sequela.

Novel COVID-19 continues to intrigue medical professionals with its varied presentations. Though it affects the respiratory tract primarily, thrombogenesis has been the Achilles' heel. A 44-year-old man diagnosed with COVID-19 presented with upper limb pain at a local hospital and was found to have thrombosis of the right axillary artery. Despite a successful embolectomy at the local hospital, there was re-occlusion of the axillary artery and the limb became ischaemic. He was referred to our institution by which time the limb became gangrenous above the elbow and had to be amputated. Extensive sloughing of the nerves was also seen in the local area. Hypercoagulability presenting with various manifestations is common in COVID-19 and needs early anticoagulation. We present this asymptomatic patient who lost a limb to this COVID-19 sequelae.

Curious case of submandibular swelling.

A 35-year-old woman presented with a progressively increasing swelling over the left side of the upper part of the neck for the past 8 months with no associated pain over the swelling. On examination, a non-tender, firm, well-defined, oval swelling of size 3×2 cm was palpable in the left submandibular region that was mobile, non-pulsatile and free from the overlying skin and the underlying muscle. Ultrasonography revealed a bilobed heteroechoic lesion in the left submandibular region with internal vascularity and multiple macrocalcification within it. During the procedure for surgically excising the swelling, we found that it was separate from the gland and vascular structures, had a sinus tracking over and around the left submandibular gland extending beyond the angle of mandible up to the root of a decayed left lower second molar tooth.

Efficacy of colistimethate sodium as local application in necrotising fasciitis.

Necrotising fasciitis (NF) is a rapidly progressive severe soft tissue infection of the deep fascia resulting in the destruction of overlying subcutaneous tissue and skin. We report the case of NF of the lower limb with a poor prognosis due to multidrug-resistant (MDR) Klebsiella pneumoniae (K. pneumoniae) sensitive only to colistin. In view of the worsening condition of the wound, risk of deterioration of renal function and economic constraints, it was decided to start on colistin therapy locally by colistimethate sodium (CMS). The patient responded well to the treatment and got clinically better. Subsequent culture sent for post-treatment showed no growth of the organism. The wound healed with regular dressings by 8 weeks. This was found to be a very cost-effective treatment modality. Local use of CMS was found to be a novel method of achieving infection-free wound especially against MDR K. pneumoniae.
