ABSTRACT
Introduction: In early 2020, restrictions were established to control the transmission of COVID-19, such as the suspension of elective public health care. Dental teleservice has become an alternative to patient follow-up. In Brazil, the Federal Council of Dentistry published Resolution 226/2020, allowing the performance of dentistry at a distance. Objective(s): To assess dentists' satisfaction with the use of the oral telediagnosis service during the COVID-19 pandemic. Material(s) and Method(s): Cross-sectional and quantitative study. An online questionnaire was released to 636 dentists in the North of Minas Gerais, Brazil, between May and September 2022, with 298 respondents. The database was built using the Statistical Package for the Social Sciences, 24.0 software. This study was approved by the CEP (#5.267.570). Result(s): There was a predominance of dentists working in the public health network (86.2%;n=257). Most profession-als reported a drop in face-to-face calls during the pandemic (94.2%;n=281), and 86.2% (n=257) had losses from their activities. Teleservice resources were used during social isolation by 75.8% (n=226) of dentists, mainly for patient follow-up (63.7%;n=190). Consultation by phone was the main virtual method (63.7%;n=190). Regarding teleservice, 58.6% (n=119) of dentists realized the system was easy to use, and 50.2% (n=101) would like to continue using it after the pandemic. Conclusion(s): This is the first Brazilian study to assess dentists' satisfaction with teleservice. It is concluded that teleservice can contribute to early diagnosis and assistance by professional users.
ABSTRACT
Teledentistry is an amalgamation of dentistry and telecommunication where the clinical information is exchanged between the patient/ caregiver with the dentist from a remote distance. The role of teledentistry came into spotlight in the pandemic Covid 19 era. This proved to be the safest method to provide health care assistance in preventing the disease transmission was cost effective and also formed a bridge between the rural and urban communities. It also helps in telediagnosis and formulation of treatment in dental emergenices. Teledentistry has improved a lot in the recent times due to advent of smart phones, widespread internet connectivity and video conferencing applications. Teledentistry could provide hassle free consultations as well the patient history can be stored in the data base for a longer period of time. This review highlights the origin, its applications, drawbacks and its role in the covid 19 and lock down phase.
ABSTRACT
Featured ApplicationThe present cross-sectional analysis aimed to evaluate the level of interest in oral and dental needs and teledentistry applications among the elderly, as well as whether COVID-19 pandemic outbreaks were influenced by real-time surveillance, using Google Trends. As the number of elderly dental patients continues to increase, there is a growing need for specific interventions that address the biological and psychological issues of this population. Teledentistry represents a healthcare delivery system that can overcome these problems, although the oral and dental care provision methods involved are still unknown to most people. Indeed, there is a need to raise awareness of the indications for teledentistry, the available interventions, and the potential benefits for the oral and dental care of elderly patients.Considering the increasing need for oral and dental care in the elderly, teledentistry has been proposed to improve the education of elderly patients in oral health maintenance and risk factor control, identify patients' concerns in advance, facilitate monitoring, and save time and money. The present cross-sectional analysis of Google search data through real-time surveillance with Google Trends aimed to determine Google users' interest in oral and dental needs and teledentistry applications in the elderly, and to compare search volumes before and after the COVID-19 outbreak. Extracted CVS data were qualitatively analyzed. Pearson and Spearman correlation analyses were performed between searches for "elderly” and "teledentistry”, and all the oral and dental needs and teledentistry applications. The Mann–Whitney U test compared search volumes in the 36 months before and after the beginning of the COVID-19 pandemic. Google users' interest in the elderly and related oral and dental needs was diffusely medium–high, while teledentistry and its applications were of lower interest. Interest in teledentistry and its applications was strongly related to interest in the older population, which is consistent with the assumption that older adults represent the population segment that could benefit most from these tools. A positive correlation was also found between searches for "Elderly” and searches for almost all oral and dental needs typical of the geriatric population. Search volumes increased significantly after the outbreak of the COVID-19 pandemic. More information about teledentistry should be disseminated to increase knowledge and awareness, especially among older patients, about its indications, applications, and advantages.
ABSTRACT
There are still many areas of India without proper medical facilities. In such a setting, technology can play a facilitating role, particularly in reaching out to remote locations and offering a greater standard of care at a lower cost. The method of treating and diagnosing patients remotely through communication networks is known as telemedicine. When more patients get access to telemedicine, payers take more notice of how much less expensive it is than traditional medicine, and doctors are aware of its benefits. Telemedicine is a more beneficial technology that can expand access to preventive treatment and may lead to long-term health. Telemedicine has the potential to greatly affect public health. This paper reviews the current state of the art of telemedicine in India. Nearly 50 years ago, telemedicine was shrugged off as a complicated, expensive, and inefficient technology. Because of how quickly the information technology and telecommunications disciplines are advancing, telemedicine is today a viable, dependable, and useful technique. Practitioners and medical experts from a variety of fields have experienced success with telemedicine. The COVID-19 pandemic highlighted the need for strong primary healthcare networks for a more effective public health response during health emergencies and exposed the fragmentation of healthcare delivery systems. Although primary care is the first point of contact between the general public and the healthcare system, it has not recently grown much focus or funding. Even in the post-COVID-19 environment, telemedicine offers the potential to get through enduring barriers to primary care in India, such as a shortage of qualified medical professionals, issues with access, and the cost of in-person care. Telemedicine has the power to speed up the delivery of universal health coverage while strengthening primary care. There is a widening gap between people and those who offer basic health services as the population in India has grown, and the average lifespan has increased. Telemedicine helps with palliative care, early identification, a better cure, prevention, and rehabilitation in the treatment of cancer. Due to a shortage of primary care delivery networks and referral units, secondary and tertiary care facilities' health systems are overworked. To successfully use telemedicine, proper planning and operating processes are required. Thus, the development and implementation of telemedicine will improve patient care and India's primary healthcare system in the future. Finally, telemedicine's cost-effectiveness will likely be its most significant outcome.

Material(s) and Method(s): This was a descriptive cross-sectional study. The study took place over a period of 3 months, from 1 October to December 30, 2020. This study was conducted on the WhatsApp group platform of the Senegalese Dentists. A total of 150 communications were included. Result(s): Public sector dentists sent more communications, 88% of the communications. By specialty, general practitioners had sent more communications, 82.7% of communications. For the oral surgery receiver site, 71% of communications were received. 65% of referring dentists had given a diagnosis. Patients with tumours and cysts represented more than half of the sample (53.3%) followed by trauma patients (18.6%). The most common infections were cellulitis (46.66%) and osteitis (33.33%). Oral and maxillofacial surgeons managed 69.33% of the pathology. Conclusion(s): WhatsApp is a fundamental contribution to the remote diagnosis and management of oral and maxillofacial pathologies, especially during the current covid-19 pandemic.Copyright © 2021
ABSTRACT
The great use of telecommunication technology propels new healthcare system of telemedicine through which diagnosis as well as treatment can be done in the remote areas. The ancient Greek language explain the terminology of telemedicine in the phrase of distance healing. As per WHO, Telemedicine is the delivery of health-care services, where distance is a critical factor, by all health-care professionals using information and communications technologies for the exchange of valid information for diagnosis, treatment and prevention of disease and injuries, research and evaluation, and the continuing education of health-care workers, with the aim of advancing the health of individuals and communities. Historically the concept of teleconsultation was evolved in the first half of twentieth century when the data of ECG was communicated through telephone lines, this can be traced as first evidence of this unique healthcare system. Further the introduction of electrical system of telegraph as well as evolution of telephone revolutionized this system of healthcare. when the Technology of telemedicine help both patients as well as service providers in multiple ways involving physicians, surgeons, pharmacists, paramedical staff, IT and electronics engineers, government, hospitals and end user public Location is now a days no problem and therefore there is no limitation of the availability of healthcare facilities to such location or remote location. The biggest role in such development is played by the communication technology which may provide healthcare services to every nook and corner of the location. It can decrease the health staff pressure because in India WHO guidelines ask to maintain the ratio 1:1000 of doctor and Indian public compared to present 0.62:1000 ratio of doctor and public. The great advantage of this system is that in case of epidemic or pandemic like COVID 19 Telemedicine can keep the health staff are well general public free from contagious infection (COVID-19). There are a number of networking communication modes that can be applied, which may improve the patient compliance,dosage regimen can be managed in better fashion thus increase the longevity of person life. Disasters management during pandemics present unique challenges which can be addressed effectively as happened during the lockdown. This technology-based practice can break the infectivity chain of the transmission of communicable diseases This chapter incorporates basic concept of telemedicine, its origin and types, communication technologies, services by telemedicine, types of telemedicine, tools of telemedicine, telemedicine software's and guidelines related to practicingtelemedicine in reference to Indian context.

ABSTRACT
Tele-Diagnosis is beneficial for medical care in areas with inadequate resources, which helps control the spread of Covid-19 in the current pandemic. Most teleoperated diagnostics are dependent on humans, possibly leading to cognitive issue caused by distanced communication. In this paper, we propose a local haptic enhancement framework to facilitate the remote palpation. The deep deterministic policy gradient (DDPG) algorithm is exploited to compensate for signal transmission due to latency, allowing human to operate without the sense of delay. With the help of weighted recursive least squares (WRLS) method, the interactive force can be estimated on the patient's side despite the lack of force sensors. Fuzzy inference is used to diagnose and classify the extent of disease based on the estimated force and motion state on the remote side, thereby leveraging the remote sensory information to conduct autonomous reasoning. Finally, the final diagnosis is derived by performing minimum risk Bayesian decision based on local and remote inference results. Comparative simulation results have validated the superior performances of the proposed scheme. © 2022 IEEE.
ABSTRACT
Purpose : During the Covid-19 era, understanding the benefits and limitations of tele-ophthalmology has become increasingly important. In this study, we aim to assess the accuracy of tele-ophthalmic diagnosis of diabetic retinopathy (DR) and diabetic macular edema (DME) when performed by resident physicians. Methods : Retrospective study on 16 patients (32 eyes;28 DR and 4 controls) who presented to a retina clinic at an academic medical center. Automated OCT-B images with 3D topographic maps and fundus photographs of the posterior pole using a Topcon Maestro 3D OCT-1 unit were taken. Images were transmitted remotely to a resident physician who assessed the severity of the DR and DME on the basis of the fundus photographs and OCT. The same images were transmitted to a retina specialist for grading. Primary outcomes included DR and DME grade as defined by the International Clinical Diabetic Retinopathy classification scale. We then tested the concordance between diagnoses rendered via tele-OCT by the resident compared to the retina attending's remote diagnosis and the gold standard retina specialist's clinical examination using Cohen's Kappa statistic (κ). Results : Agreement between ophthalmology residents and attendings on tele-OCT diagnosis of DR was substantial (78% concordance on presence and 75% on severity), while agreement on identifying and grading edema was moderate (60% concordance on DME presence and 52% concordance on overall DME severity). Detection of DR by residents via tele-retinal imaging is highly sensitive (100% sensitivity), while detection of DME is highly specific (79-95% specificity). Discordance between residents and attendings on DME grading may owe to differences in opinion regarding what constitutes mild edema versus no edema;however, both concordance and predictive accuracy increase when identifying patients with moderate to severe DME. Conclusions : This study provides proof of principle for the sensitivity and specificity for remote diagnosis of DR via tele-OCT fundus and OCT-B images. This technology may be useful in identifying patients at risk of severe vision loss and enable early detection of patients who need referral for prompt treatment. These findings may be particularly relevant to training programs looking to implement tele-retinal diabetic screening or using tele-OCT where prompt access to a retina specialist may not be possible.
ABSTRACT
COVID-19 can directly or indirectly cause lung involvements by crossing the upper airways. It is essential to quickly detect the lung involvement condition and to follow up and treat these patients by early hospitalization. In recent COVID-19 diagnosis procedure, PCR testing is applied to the samples taken from the patients and a quarantine period is applied to the patient until the test results are received. As a complement to PCR tests and for faster diagnosis, thin-section lung computed tomography (CT) imaging is used in COVID-19 patients. In this study, it is aimed to develop a method that is as reliable as CT, and compared to CT, less risky, more accessible, and less costly for the diagnosis of COVID-19 disease. For this purpose, first speech and cough sounds from the oral, laryngeal and thoracic regions of COVID-19 patients and healthy individuals were obtained with the multi-channel voice recording system we proposed, the obtained data were processed with machine learning methods and their accuracies in COVID-19 diagnosis were presented comparatively. In our study, the best results were obtained with the features extracted from the cough sounds taken from the oral region. © 2022 IEEE.
ABSTRACT
Presently, the whole world is suffering from the Covid-19 pandemic. In this harmful situation, using information and Internet technology is mandatory for the government and medical practitioners. After the lockdown, the government needs to take important decisions to allow passengers to travel through air, rail, and land. In the present situation, people need to get a medical report from the hospitals to travel through various modes of transport. In this regard, the Covid-19 history of the passengers plays an important role in issuing tickets to the passengers. Hence, in this paper, a novel authentication method using InterPlanetary File System (IPFS) is suggested to retrieve the Covid-19 history of all passengers to determine whether to issue tickets and allow people to travel through various modes of transport. The government can share the Covid-19 status of passengers with the ticket issuing authority. The medical practitioners can share medical reports and medical images of such people for telediagnosis. To provide security, a novel privacy-preserving storage and sharing of Covid-19 records using secure authentication and image cryptosystem are proposed using chaos, cryptographic hash (SHA-256), Paillier cryptosystem, and IPFS. Security analysis shows that the system can withstand various kinds of attacks.
ABSTRACT
Teledentistry has been proven to have the potential in addressing the gap in accessing oral health care worldwide. Nevertheless, more information is needed to support evidence-based teledentistry practice in Malaysia. The article aims to review teledentistry in view of implementing it to be a common practice in Malaysia. The authors describe teledentistry application worldwide, as well as its uses in the field of service and education. The article summarises the needs of teledentistry in South East Asia, as well as the ethical perspectives and legal practices. In addition, the article also reviews the opportunities arising from practicing teledentistry, including during the unprecedented COVID-19 pandemic. Following review, teledentistry seems to be a promising path as it could offer solutions to shortages in the workforce, high demand for treatment needs and unequal service distribution due to lack of accessibility in rural areas in Malaysia. Furthermore, teledentistry can extend care to underserved patients and provide opportunities to supplement teaching in dental education. The authors provide recommendations to overcome challenges to ensure a sustainable teledentistry. Incorporating teledentistry into practice in Malaysia is achievable but proper guidelines are required. © Penerbit Universiti Sains Malaysia. 2022 This work is licensed under the terms of the Creative Commons Attribution (CC BY) (http://creativecommons.org/licenses/by/4.0/).
ABSTRACT
BACKGROUND: Owing to the COVID-19 pandemic, social distancing has become mandatory. Wireless endoscopy in contactless examinations promises to protect health care workers and reduce viral spread. OBJECTIVE: This study aimed to introduce a contactless endoscopic diagnosis system using a wireless endoscope resembling a mask. METHODS: The Wi-Fi-based contactless mask endoscopy system comprises a disposable endoscope and a controller. First, the effective force applied by the tip during insertion was evaluated in a simple transoral model consisting of a force sensor on a simulated oropharynx wall. Second, the delay in video streaming was evaluated by comparing the frame rate and delays between a movement and its image over direct and Wi-Fi connections. Third, the system was applied to a detailed laryngopharyngeal tract phantom. RESULTS: The smartphone-controlled wireless endoscopy system was successfully evaluated. The mean, maximum, and minimum collision forces against the wall of the transoral model were 296 mN (30 gf), 363 mN (37 gf), and 235 mN (24 gf), respectively. The delay resulting from the wireless connection was 0.72 seconds. Using the phantom, an inexperienced user took around 1 minute to orient the endoscope to a desired area via the app. CONCLUSIONS: Device articulation does not pose a significant risk of laryngopharyngeal wall penetration, and latency does not significantly impede its use. Contactless wireless video streaming was successful within the access point range regardless of the presence of walls. The mask endoscope can be controlled and articulated wirelessly, minimizing contact between patients and device operators. By minimizing contact, the device can protect health care workers from infectious viruses like the coronavirus.

Aim: The aim of the study was to present the results and impact of the application of artificial intelligence (AI) in the rapid diagnosis of COVID-19 by telemedicine in public health in Paraguay. Methods: This is a descriptive, multi-centered, observational design feasibility study based on an AI tool for the rapid detection of COVID-19 in chest computed tomography (CT) images of patients with respiratory difficulties attending the country's public hospitals. The patients' digital CT images were transmitted to the AI diagnostic platform, and after a few minutes, radiologists and pneumologists specialized in COVID-19 downloaded the images for evaluation, confirmation of diagnosis, and comparison with the genetic diagnosis (reverse transcription polymerase chain reaction (RT-PCR)). It was also determined the percentage of agreement between two similar AI systems applied in parallel to study the viability of using it as an alternative method of screening patients with COVID-19 through telemedicine. Results: Between March and August 2020, 911 rapid diagnostic tests were carried out on patients with respiratory disorders to rule out COVID-19 in 14 hospitals nationwide. The average age of patients was 50.7 years, 62.6% were male and 37.4% female. Most of the diagnosed respiratory conditions corresponded to the age group of 27-59 years (252 studies), the second most frequent corresponded to the group over 60 years, and the third to the group of 19-26 years. The most frequent findings of the radiologists/pneumologists were severe pneumonia, bilateral pneumonia with pleural effusion, bilateral pulmonary emphysema, diffuse ground glass opacity, hemidiaphragmatic paresis, calcified granuloma in the lower right lobe, bilateral pleural effusion, sequelae of tuberculosis, bilateral emphysema, and fibrotic changes, among others. Overall, an average of 86% agreement and 14% diagnostic discordance was determined between the two AI systems. The sensitivity of the AI system was 93% and the specificity 80% compared with RT-PCR. Conclusion: Paraguay has an AI-based telemedicine screening system for the rapid stratified detection of COVID-19 from chest CT images of patients with respiratory conditions. This application strengthens the integrated network of health services, rationalizing the use of specialized human resources, equipment, and inputs for laboratory diagnosis.
ABSTRACT
Aim: To examine whether two existing cognitive screeners might be adapted for telephone administration by omission of item content requiring visual cues or assessment. Materials & methods: Data from a test accuracy study of Mini-Addenbrooke's Cognitive Examination (MACE) and Free-Cog were used to derive scores for 'Tele-MACE' and 'Tele-Free-Cog'. Results: As in the index study, both Tele-MACE and Tele-Free-Cog proved sensitive for dementia diagnosis. Tele-MACE had a better balance of sensitivity and specificity than observed with MACE. Tele-MACE was sensitive for mild cognitive impairment diagnosis, whereas Tele-Free-Cog was more specific for mild cognitive impairment. Conclusion: Existing cognitive screeners may be adapted for telephone administration. Such developments may prove necessary in the COVID-19 era as remote rather than face-to-face cognitive assessment increasingly becomes the established norm.
