Background
The coronavirus disease 2019 pandemic has posed a new challenge for medical educators worldwide. While teaching and learning shifted online, assessment posed a roadblock. A pilot study was performed to check the feasibility and acceptability of online open-book examination.
Methods
A pilot study was carried out on sixth semester (fourth year) students. An online open-book examination was conducted on an ENT topic, and feedback was obtained using a pre-validated questionnaire. Two teachers scored and collated the answers, and the marks were averaged for each candidate.
Results
Ninety-eight students appeared for the examination: 21.4 per cent failed and 78.6 per cent passed. Eight students scored above 75 per cent correct. Only 55 students volunteered to give feedback; most agreed that the best advantage of this assessment was that it was stress-free. The disadvantage most complained of was network connectivity issues.
Conclusion
Online open-book examination has the potential to be the new normal in the present circumstances and beyond.
Introduction
Majority of petrous bone and lateral skull base pathologies are benign in nature. The complex anatomy usually warrants an extensive approach with associated morbidity.
Case summary
Two cases of petrous bone cholesteatoma (1 congenital cholesteatoma with facial palsy and 1 acquired cholesteatoma) and a case of glomus tympanicum were treated with exclusive endoscopic transcanal approach. The cases of petrous cholesteatoma were addressed with trans-promontorial and infra-cochlear approaches. The mean operative time was approximately 140 min. No CSF otorrhoea was noticed in the post-operative period. The average period of hospital stay was 3.7 days.
Conclusion
In the subset of cases with limited benign disease an endoscopic trans-canal approach is a better alternative to an external approach. It decreases operative time, blood loss, chance of meningitis, morbidity and hospital stay. The lack of depth perception is a major hurdle which can be come over by experience in endoscopic middle ear surgery. This approach can create direct access to cochlea/petrous apex/internal auditory canal (IAC)/Supra-geniculate ganglion region.
The predisposing factors of invasive fungal disease in COVID 19 infection are still debatable because of the limited human understanding of the virus with the current literature. In this study, we have tried to correlate the various predisposing factors influencing the clinical profile and treatment outcomes in patients with covid associated mucormycosis (CAM). It is a retrospective analysis of cases of CAM during the second wave of COVID 19 infection, which was managed in the department of Otorhinolaryngology from Dec 1, 2020, to June 10, 2021. The detailed clinical, radiological and management of patients with CAM were collected, recorded, evaluated and correlated with the predisposing factors. Of the total, 46 patients, 44(95.65%) were diabetic and 41 patients had a previous history of steroid intake. When clinical parameters were compared between blood sugar < 200 mg/dl and > 200 mg/dl, the old and newly diagnosed diabetes mellitus in patients with CAM, there was no significant differences in any of the above clinical parameters (
p
> 0.05), except the hospital stay (
p
= 0,004). Steroid intake in patients with coexisting DM associated with CAM is considered the most important factor for the development of the CAM. There was are no significant difference in any of the clinical/treatment outcomes in patients with CAM with respect to the initial blood sugar, except for the hospital stay. A large sample size with a long-term follow-up period may be needed for a better understanding of common predisposing factors for the development of CAM.
To compare efficacy of temporalis fascia myringoplasty using platelet-rich plasma(PRP) {MP-PRP} and conventional emporalis fascia myringoplasty (MP-C) in treatment of moderate to large central tympanic-membrane(TM) perforation. Randomized-Control-Trial. We randomly assigned eighty-patients with COMmucosal-type with medium to large central TM-perforation and conductive hearing loss planned for primary myringoplasty to receive either MP-PRP orMP-C. Myringoplasty was performed through postauricular approach underlay graft using temporalis fascia. Primary-outcome was graft uptake (an intact TM) at 6 months postoperatively. Secondaryoutcome was the postoperative hearing improvement measured by pure-tone-audiometry (PTA). Eightymyringoplasties (MP-PRP group-40, MP-C group-40) done for 80 patients (male = 41; female = 39, age-group = 18-45-years) were included in analysis. At 6 months postoperatively graft uptake rate was 94.4% in MP-PRP and 92.1%% in MP-C group. There was no statistically significant difference in graft-uptake between the two groups (p = 0.358). Success in terms of hearing gain (C 10 dB) was achieved in 34 patients (89.5%) in MP-C and 37 patients (94.9%) in MP-PRP group. At 6 months follow-up; mean-PTA-average improved from 35.10 ± 5.401 dB to 27.74 ± 5.660 dB and mean ABG improved from 24.00 ± 5.204 dB to17.42 ± 5.559 dB in MP-C group. At 6 months followup; mean-PTA-average improved from 37.00 ± 6.144 dB to 26.65 dB and mean air bone gap (ABG) improved from 25.98 ± 5.736 dB to 16.21 ± 4.318 dB in MP-PRP group. No statistically significant differences in improvement in PTA-values were observed between both groups (p = 0.336).Postoperative complications were similar in both groups. Graft-uptake, hearing outcomes and complications of MP-PRP were similar to MP-C. MP-PRP offers no advantages over MP-C for treatment of TM perforation.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
