ABSTRACT
As part of preventing the rapid spread of the COVID-19 virus, masks should be used besides physical distancing, avoiding crowds, setting good ventilation, cleaning hands, and more. In fact, there are still many people who do not use masks in public places. Security officers usually carry out the supervision system for the use of masks in public places. Direct interaction between security officers and many visitors in the long term will trigger a high risk of being infected. It is better if there is a system that can monitor the use of masks automatically and continuously. In this study, a deep learning algorithm with YOLOv3 architecture is applied to a web-based mask detection system. YOLOv3 is one of the best algorithms that has been widely applied and optimized by researchers for object detection. This system has been tested in two scenarios using different data sets, namely without augmentation and with augmentation. For each scenario, three experiments were carried out using varying amounts of training data, namely 10, 100, and 800. The best mAP and confidence values were obtained from experiments using 800 training data with augmentation. This mAP value is 0.99 with a confidence value range between 0.9 to 1. © 2021 IEEE.
ABSTRACT
Aim: To identify the prevalence of bacterial and viral conjunctivitis. Study design: Prospective study. Place and Duration of Study: Department of Ophthalmology, Pakistan Railways Hospital, Islamic International Medical College, Rawalpindi from 1st April 2021 to 30th September 2021. Methodology: Fifty conjunctivitis patients enrolled within age of 14-29 years. Clinical examination, slit lamp test and lab testing separated cases as viral or bacterial conjunctivitis. Polymerase chain reaction post culturing was sued in viral conjunctivitis cases while Kirby-Baur disc diffusion assay was sued in bacterial conjunctivitis confirmation. Results: There were 91.17% patients with viral conjunctivitis in age of 24-29 years and 62.5% patients with bacterial conjunctivitis within 14-18 years. The odds ratio value between the male and female gender showed a significant difference between both genders with 95% confidence interval with higher female frequency in both. Coronavirus cases were highest with 52.9% while cases of Micrococciwere highest as 37.5% with conjunctivitis. Conclusion: Viral conjunctivitis was more common in general cases due to recent covid-19 infection followed by Micrococci bacterial conjunctivitis.
ABSTRACT
Objective: To see the impact of Covid-19 on the morphology of cataract during lockdown. Study Design: Observational and interventional study. Place and Duration of Study: Department of Ophthalmology, Niazi Medical and Dental College from 1st April 2020 to 30th September 2020. Methodology: All the patients of eye related complaints were referred to eye department from emergency of hospital after screening them for Covid-19 suspected symptoms as well as patients coming directly to eye OPD from reception. Patients suffering from phacomorphic, phacolytic glaucoma and cataract of every type except traumatic type were included. Results: The ratio of males and females patients was almost equal because cataract is a common age related problem in both sexes. Due to lock down there is a significant increase in the number of mature cataract as well as phacomorpic and phacolytic glaucoma which was decreased for last many years .Although the awareness increased regarding cataract surgery but due to stop of elective work like other specialties and COVID 19 become the focus point the morphology of cataract changed (mature and hypermature), complicated cataract (phacomorphic, phacolytic glaucoma) irrespective of socioeconomic status of patients. Conclusion: During lockdown period there is increase in the maturity of cataracts and secondary glaucoma (phacolytic, phacomorphic). Although this pattern of cataract presentation has been decreased for last many years but due to covid 19 strong lock down occur and this pattern was again observed.
ABSTRACT
Background: COVID-19 not only jeopardized the health, economy but also the education. Medical education is the worst affected area. Shift from traditional learning to online teaching brings forth new kind of complexity in teaching and learning behavior. Student's attitude towards digital world, availability of resource, their capacity to use and learn from online teaching, institutional conversion and adoption of online method of teaching and their impact all are expected concerns. This study is the reflection of female medical student's status and perception during Covid 19 pandemic. Objective: To assess the affect of covid-19 pandemic on medical education among female medical students. Study Design: Place and Duration of Study: Department of Ophthalmology, Pak Red Crescent Medical & Dental College Kasur from 1st January 2021 to 31st August 2021. Methodology: Questionnaire was generated based on student's interview, feedback and literature review. Question was of yes/no type. Impact of Covid19 was assessed, working potential, future planning, availability of resources, role of institution, knowledge, attitude and mental and physical well being. Questionnaire was distributed and collected after 24 hours, majority responders were female. Results: There were 29 students with average age of 21.3±2 years, who responded to the survey, among them only 2 were males. 86.2% claimed negative impact of Covid-19. 34.5% had mild, 37.9% moderate and 24.1% had severe anxiety. Only eight (27.6%) students worked as frontline worker or volunteer during pandemic with highest rate (66.7%) among final year or house officers. Majority (93.0%) were aware of the COVID-19 infection and its consequences. Social media was the major source of information for 79.3% followed by WHO web site, faculty lectures, government health advisors and conference/symposia at campus. A good number (65.5%) were willing to work as frontline worker, 58.6% had their families no objection on their working as frontline workers.13.8% did not have digital devices. 58.6% were satisfied with internet function. Conclusion: Majority student's physical and mental wellbeing affected by Covid. Most were aware of Covid and its consequences. Institution need to integrate online teaching method into traditional way of learning. More resources should be directed for education and provision of facility.
ABSTRACT
The ongoing COVID-19 pandemic caused by the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) has resulted in significant death and morbidity rates around the globe. SARS-CoV-2 infection has been linked to 43.3 million confirmed cases worldwide, killing 1.15 million people. Physical separation, quarantine, and isolation were successful in minimizing the number of individuals who became sick during the epidemic, but the lack of immunity in the community makes them vulnerable to further waves of SARS-CoV-2 infection. Elderly persons (those 60 and older) and those with pre-existing medical problems are particularly vulnerable. Material and Methods: In this observation study, people who were vaccinated with sinopharm vaccine and sinovac vaccine were included to see the response of vaccine in the body. The aim of the study was to compare the rise in the antibody level after 2 doses of two different COVID-19 vaccines i.e sinopharm and sinovac. Initially, in this pilot study, 40 people were included randomly from our health care team, after proper informed consent regarding the study. Results: Among total 40 people were involved, male were 21 of 40 (52.5%) and female were 19 of 40 (47.5%). Most of the individuals were doctors (26 of 40, 65%). Mean age, weight, height and body mass index (BMI) are also shown below. Conclusion: This study was to report the response of people of Pakistan toward sinopharm and sinoVac vaccines in terms of COVID antibody level. Response of the body was around 40 to 50% for sinopharm and 50 to 70 percent towards CoronaVac vaccine. Further data collection is being done to improve sample size and better outcome.
