COVID-19 Pandemic and Telephone Triage before Attending Medical Office: Problem or Opportunity?

Provider and Patient Satisfaction with Telemedicine Voice Therapy During the COVID-19 Pandemic

OBJECTIVES

The COVID-19 pandemic expanded the use of telemedicine, but there is no literature exploring both patient and provider satisfaction specifically in the provision of voice therapy. This study aims to investigate patient and provider satisfaction with virtual voice therapy, its associated factors, and any correlation between the two.

METHODS

Cross-sectional study. Participants included 226 adults who underwent voice therapy delivered via telepractice at the USC Voice Center between April and October 2020. Patients and providers self-reported their level of satisfaction on a visual analog scale (VAS; range 0-100). Patient satisfaction was additionally measured using a previously validated Telemedicine Satisfaction Questionnaire (TSQ; range 1-5), and a binary question about their desire to choose telemedicine over in-person therapy in the future. Three speech-language pathologists rated provider satisfaction for all 226 patients. Patient satisfaction survey was completed by 55 patients. Multivariable linear regression analyses and linear mixed-effects models were used to assess the results.

RESULTS

Patient and provider mean (SD) VAS satisfaction scores were 86.8 (18.6) and 80.6 (19.7), respectively. The mean (SD) TSQ score was 4.4 (0.6). In a multivariable model, patient satisfaction levels were significantly higher for hypofunctional than for hyperfunctional dysphonia diagnoses. Forty-four (73%) patients reported they would prefer telemedicine voice therapy over in-person appointments, which was significantly correlated with internet reliability (P = 0.04). For providers, satisfaction was significantly lower for patients whose diagnosis had changed after initiation of voice therapy (Δ = -16.0 [95% CI: -28.7 to -3.2]) and for encounters with Asian patients compared to White patients (Δ = -11.6 [95% CI: -18.9 to -4.2]). Patient and provider satisfaction scores were weakly correlated (r = 0.19).

CONCLUSIONS

Our findings suggest that virtual voice therapy is not simply an alternative to in-person service, but rather an effective method useful beyond the current pandemic with proper diagnosis and technical support.

Adaptation in communication technology utilization: caring for individuals with chronic conditions in South Asia during the Covid-19 pandemic

BACKGROUND

During the Covid-19 pandemic, people with chronic conditions experienced delayed or missed care, while their carers endured social isolation, loneliness, and reduced support. Information communication technology (ICT) can be utilized to encourage continuity of care, address misinformation, and allocate support. This study aimed to identify factors associated with the ICT adaptation of South Asian carers of individuals with chronic conditions by comparing changes in ICT utilization and preferences before and during the pandemic.

METHOD

416 South Asian carers reporting feelings of loneliness and isolation were identified from the Coping with Loneliness, Isolation and Covid-19 (CLIC) online survey. Descriptive statistics and multinomial regression models were utilized.

RESULT

The most commonly used ICT modality was auditory, followed by written and audio-visual. Four variables identified were: social network size and relationship proximity, Covid-19-induced distress, age, and living arrangements. We identified a negative correlation between social network size and ICT frequency/intensity, reductions in communication frequency/intensity associated with Covid-19-induced distress, working-age carer (18-60) preference adaptation toward written communication during the pandemic, written and auditory ICT fluency in carers spending time alone by choice, and aversion from auditory ICT in carers who lived and were often alone involuntarily.

CONCLUSION

The findings provide insights into South Asian carers' ICT usage, preferences, and adaptation in response to the pandemic. The findings aid in the development of health and social care pathways that fulfil local caregivers' unmet support and resource needs.

Breaking Sound Barriers: Exploring Tele-Audiology's Impact on Hearing Healthcare

Hearing impairment is a global issue, affecting billions of people; however, there is a gap between the population affected by hearing loss and those able to access hearing healthcare. Tele-audiology, the application of telemedicine in audiology, serves as a new form of technology which aims to provide synchronous or asynchronous hearing healthcare. In this article, we reviewed some recent studies of tele-audiology-related topics to have a glimpse of the current development, associated challenges, and future advancement. Through the utilization of tele-audiology, patients can conveniently access hearing healthcare, and thus save travel costs and time. Recent studies indicate that remote hearing screening and intervention are non-inferior to the performance of traditional clinical pathways. However, despite its potential benefits, the implementation of tele-audiology faces numerous challenges, and audiologists have varying attitudes on this technology. Overcoming obstacles such as high infrastructure costs, limited reimbursement, and the lack of quality standards calls for concerted efforts to develop effective strategies. Ethical concerns, reimbursement, and patient privacy are all crucial aspects requiring in-depth discussion. Enhancing the education and training of students and healthcare workers, along with providing relevant resources, will contribute to a more efficient, systematic hearing healthcare. Future research will aim to develop integrated models with evidence-based protocols and incorporating AI to enhance the affordability and accessibility of hearing healthcare.

Triage of patients and remote consultations in primary care facilities during the COVID-19 pandemic in France (PRICOV-19 study)

Introduction

PRICOV-19 is a European cross-sectional study based on an online questionnaire, describing the impact of the pandemic on primary care structures (PCS). In France, PCS are solo practices (SP), single or multi-professional group practices (GP), coordinated practice structures (CPS): health houses and health centers. Triage, whether it is digital (TD), by telephone (TT) or at the reception (TR), is essential to reduce the risk of infection, and is part of recommended organizational practices.

Purpose of research

Based on French data from the PRICOV-19 study, the objective is to describe the frequency and factors associated with triage in PCSs during the COVID 19 pandemic.

Results

1100 structures responded to the survey. The TD was implemented in 64% of PCSs (53.3% of SPs, 64.9% of GPs, 73.2% of CPSs). The TT was implemented in 76% of structures (72.7% of SPs, 75.4% of GPs and 81% of CPSs). Finally, TR was implemented in 52% of structures (37.7% of SPs, 52% of GPs and 67% of CPSs). The other positively associated factors are the urban territory and the lower workload for the TD, and the presence of a receptionist for the TR.

Conclusions

Triage practices seem to be clearly associated with the organization and working conditions in the PCSs, and first and foremost with the type of structure.

Telemedicine technologies and applications in the era of COVID-19 pandemic: A systematic review

INTRODUCTION

Telemedicine services saw substantial surges in their use during the COVID-19 pandemic due to the lockdowns and characteristics of the pandemic. Therefore, the authors aimed to systematically review the telemedicine services provided during the COVID-19 pandemic and their potential applications.

METHODS

The authors searched PubMed, Scopus, and Cochrane databases on September 14, 2021. Then, the retrieved records underwent two-step title/abstract and full-text screening processes, and the eligible articles were included for qualitative synthesis.

RESULTS

The review of studies demonstrated that the telephone is listed 38 times, making it the most common technology used in telemedicine. Video conferencing is also mentioned in 29 articles, as well as other technologies: Mobile-health (n = 15), Virtual reality (n = 7). According to the findings of the present study, Tele-follow-up (n = 24), Tele-consulting (n = 20), Virtual visits (20), and Tele-monitoring (n = 18) were the most widely used telemedicine applications.

CONCLUSION

Telemedicine has been an effective approach to COVID-19 management. Telemedicine technology is going to play a key role in the future of health medicine, patient consultation, and many other extended applications of health care in remote rural locations.

Operational Status of Isolation Rooms in Emergency Departments and Patient Concentration in Higher-Level Emergency Departments in Daegu Metropolitan City and Neighboring Provinces, South Korea, during the COVID-19 Pandemic

BACKGROUND

In a pandemic situation such as the one of the COVID-19 pandemic, nosocomial transmissions attempted to be prevented by initially classifying them in triage. Therefore, emergency departments (EDs) installed isolation rooms at their entrance. Additionally, a system for pre-emptive quarantine at the triage stage was established nationwide for patients with COVID-19-related symptoms.

METHODS

Data were retrospectively collected from 28,609 patients who visited the regional emergency medical center of Yeungnam University Hospital in Daegu Metropolitan City in 2021. The study population was divided into experimental and control groups comprising patients with and without COVID-19-related symptoms, respectively. The difference in the percentage of patients visiting from outside the city was investigated between the two groups. The critically ill patient (CP) ratio was analyzed in the experimental group to verify the appropriateness of visiting a higher-level ED and was further divided into sub-regions to determine their reason for visiting an ED beyond their residential region.

RESULTS

Most lower-level EDs did not have isolation rooms. About 20.1% and 17.3% of patients in the experimental and control groups visited a higher-level ED with an isolation room beyond their residential region, respectively. The absence of an isolation room in the ED in their residential region was one reason for traveling beyond their residential region, with an odds ratio of 4.44 (95% confidence interval: 0.53-8.35).

CONCLUSION

In the process of implementing the "pre-emptive quarantine" system, it was revealed that the cooperation of the lower-level EDs was not effective during the implementation of the "pre-emptive quarantine" system. Consequently, a higher number of patients with COVID-19-related symptoms had to locate an ED with an isolation room and travel a longer distance than general patients. The participation of more EDs is required.

Using a national level cross-sectional study to develop a Hospital Preparedness Index (HOSPI) for Covid-19 management: A case study from India

Background

We developed a composite index–hospital preparedness index (HOSPI)–to gauge preparedness of hospitals in India to deal with COVID-19 pandemic.

Methods

We developed and validated a comprehensive survey questionnaire containing 63 questions, out of which 16 critical items were identified and classified under 5 domains: staff preparedness, effects of COVID-19, protective gears, infrastructure, and future planning. Hospitals empaneled under Ayushman Bharat Yojana (ABY) were invited to the survey. The responses were analyzed using weighted negative log likelihood scores for the options. The preparedness of hospitals was ranked after averaging the scores state-wise and district-wise in select states. HOSPI scores for states were classified using K-means clustering.

Findings

Out of 20,202 hospitals empaneled in ABY included in the study, a total of 954 hospitals responded to the questionnaire by July 2020. Domains 1, 2, and 4 contributed the most to the index. The overall preparedness was identified as the best in Goa, and 12 states/ UTs had scores above the national average score. Among the states which experienced high COVID-19 cases during the first pandemic wave, we identified a cluster of states with high HOSPI scores indicating better preparedness (Maharashtra, Tamil Nadu, Karnataka, Uttar Pradesh and Andhra Pradesh), and a cluster with low HOSPI scores indicating poor preparedness (Chhattisgarh, Delhi, Uttarakhand).

Interpretation

Using this index, it is possible to identify areas for targeted improvement of hospital and staff preparedness to deal with the COVID-19 crisis.

A Review on Risk Management of Coronavirus Disease 19 (COVID-19) Infection in Dental Practice: Focus on Prosthodontics and All-Ceramic Materials

Background: A novel β-coronavirus infection (COVID-19) was first detected in Wuhan city, spreading rapidly to other countries and leading to a pandemic. Dental professionals and patients are exposed to a high risk of COVID-19 infection, particularly in the prosthodontic practice, because of the bio-aerosol produced during teeth preparation with dental handpieces and the strict contact with oral fluids during impression making. This paper aimed to provide an overview to limit the risk of transmission of COVID-19 infections during prosthetic procedures in dental offices. Methods: An electronic search was conducted on the electronic databases of PubMed/Medline, Google Scholar, Embase, Scopus, Dynamed, and Open Grey with the following queries: (COVID-19) AND/OR (SARS-CoV-2) AND/OR (Coronavirus) AND/OR (contaminated surface) AND/OR (cross-infection) AND/OR (Prosthodontics) AND/OR (dental ceramic) AND/OR (glass-ceramic). A manual search was performed as well. Results: From the 1023 collected records, 32 papers were included. Conclusions: Dental offices are at high risk of spreading SARS-CoV-2 infection due to the close contact with patients and continuous exposure to saliva during dental procedures. Therefore, pre-check triages via telephone, decontamination, the disinfection of impressions, the sterilization of scanner tips, and the use of specific personal protective equipment, dental high-speed handpieces with dedicated anti-retraction valves, and effective mouthwashes are strongly recommended.

Air Quality in a Dental Skills Lab during the SARS-CoV-2 Pandemic: Results of an Experimental Study

Objectives

The study aimed to analyze different ways to control air quality during/after aerosol-generating procedures (AGPs) in a small skills lab with restricted natural air ventilation in preclinical dental training (worst-case scenario for aerogen infection control). Different phases were investigated (AGP1: intraoral high-volume evacuation (HVE); AGP2: HVE plus an extraoral mobile scavenger (EOS)) and afterward (non-AGP1: air conditioning system (AC), non-AGP2: AC plus opened door).

Methods

Continuous data collection was performed for PM1, PM2.5, and PM10 (µg/m³), CO2 concentration (ppm), temperature (K), and humidity (h⁻¹) during two summer days (AGP: n = 30; non-AGP: n = 30). While simulating our teaching routine, no base level for air parameters was defined. Therefore, the change in each parameter (Δ = [post]-[pre] per hour) was calculated.

Results

We found significant differences in ΔPM2.5 and ΔPM1 values (median (25/75th percentiles)) comparing AGP2 versus AGP1 (ΔPM2.5: 1.6(0/4.9)/−3.5(−10.0/−1.1), p=0.003; ΔPM1: 1.6(0.6/2.2)/−2.2(−9.3/−0.5), p=0.001). Between both non-AGPs, there were no significant differences in all the parameters that were measured. ΔCO₂ increased in all AGP phases (AGP1/AGP2: 979.0(625.7/1126.9)/549.9(4.0/788.8)), while during non-AGP phases, values decreased (non-AGP1/non-AGP2: −447.3(−1122.3/641.2)/−896.6(−1307.3/−510.8)). ∆Temperature findings were similar (AGP1/AGP2: 12.5(7.8/17.0)/9.3(1.8/15.3) versus non-AGP1/non-AGP2: −13.1(−18.7/0)/−14.7(−16.8/−6.8); p ≤ 0.003)), while for ∆humidity, no significant difference (p > 0.05) was found.

Conclusions

Within the limitations of the study, the combination of HVE and EOS was similarly effective in controlling aerosol emissions of particles between one and ten micrometers in skill labs during AGPs versus that during non-AGPs. After AGPs, air exchange with the AC should be complemented by open doors for better air quality if natural ventilation through open windows is restricted.

Plastic Surgery Practice during COVID Times

Introduction  COVID-19 has affected plastic surgeons like never before. We conducted an all-India survey to find how the practice was affected among public/private sector, reconstructive/aesthetic practice, and consultants/residents. We have proposed some solutions to the identified problems, which are supported by previous literature.

Methods  A survey framed in Google forms was circulated through WhatsApp and emails in August 2020. Closed and semiopen questions regarding changes in personal and professional lives, coping strategies adopted, and open questions for suggestions in improving practice, academics and measures to tackle the pandemic were included. Responses were collected in an Excel sheet and analysis done using SPSS software.

Results  A total of 220 consented responses were obtained. Public hospital practitioners had to bear the COVID-related administrative as well as executive works, especially residents, which led to anxiety, family concern, burnout, and concern about the loss of skills and academics. Patient interaction was also reduced. Aesthetic surgeons bore more financial loss.

Conclusions  Plastic surgeons in India faced decrease in caseload, financial loss, COVID-related duties, workload for residents, reduced academics, family and mental health problems, difficulty with personal protection equipment (PPE) during surgeries, and queries from patients. These can be solved by doing cases within the limits of protocols and safety, pooling public and private sector for COVID duties, rotating residents' groups to reduce workload, using telemedicine for academics and patient consultations, and providing social support groups to surgeons.

Educational Videos as an Adjunct Learning Tool in Pre-Clinical Operative Dentistry—A Randomized Control Trial

Background: E-learning is an important adjunct used for teaching clinical skills in medicine dentistry. This study evaluated and compared the effectiveness of e-learning resources as an additional teaching aid to traditional teaching methods in male and female students and based on CGPA scores in a pre-clinical operative skill course. Methods: A randomized control trial was conducted in the College of Dentistry, Jouf University, to assess the impact of e-learning resources in learning clinical skills in a pre-clinical operative dentistry course. Fifty second-year dental students were randomly divided into two groups, with 25 students each. Group A (control group) was taught using traditional teaching methods, and Group B (intervention group) used e-learning resources along with traditional methods. Both groups were assessed using objective structured clinical examinations (OSCEs). Standardized forms prepared by faculty members were used to assess the students. The students also filled in a questionnaire afterwards to provide feedback regarding the e-learning resources. Results: The difference between both groups was statistically significant (p < 0.05). Female students performed better in three OSCE stations out of six. Furthermore, the students positively responded to the use of additional resources. Conclusion: The use of e-learning resources in pre-clinical operative dentistry courses can be a useful adjunct to traditional teaching methods and can result in better learning of dental pre-clinical operative skills.

Accessibility to Non-COVID Health Services in the World During the COVID-19 Pandemic: Review

Background: COVID-19 pandemic caused by SARS-CoV2 has seriously impacted the global economy. Medical facilities around the world were not prepared for the enormous challenges posed by the growing number of patients each day, the shortage of personal protective equipment, and insufficient numbers of medical staff. Governments have tried to counteract the impact of the pandemic, but the measures taken have not always been sufficient to maintain access to and quality of health services at the same level as before the pandemic. The disruption of health services has resulted in more and more research reports from different parts of the world on the accessibility of health services during the COVID-19 pandemic. Methodology: This review article presents 21 selected scientific studies on access to health services in different regions of the world. Articles were found in PubMed, GoogleScholar, Medline, and ScienceDirect databases, then grouped, and significant data were extracted from each article. The results were summarized in a table. Results: The range of limited health services included a variety of specialties, including primary care, psychiatry, orthopedics, cardiology, neurosurgery, and more. Methods used in the studies were based on retrospective analysis or on the subjective assessment of patients in the form of a questionnaire or interview. Most authors claimed a decrease in accessibility to health services during the COVID-19 pandemic compared to the pre-pandemic period, including a decrease in planned surgeries, doctor appointments, patient admission to hospital or ER, and access to medicines. Additionally, some authors observed an increase in the mortality rate. One of the few medical services that have expanded rapidly during the pandemic was online appointments. Conclusions: The COVID-19 pandemic has most certainly affected the accessibility of health services worldwide. Lessons should be learned to prevent inaccessibility to medical services, especially as experts predict another wave of COVID-19 cases.

Wireless Networking-Driven Healthcare Approaches in Combating COVID-19

Since its outbreak, the coronavirus (COVID-19) pandemic has caused havoc on people's lives. All activities were paused due to the virus's spread across the continents. Researchers have been working hard to find new medication treatments for the COVID-19 pandemic. The World Health Organization (WHO) recommends that safety and self-measures play a major role in preventing the virus from spreading from one person to another. Wireless technology is playing a critical role in avoiding viral propagation. This technology mainly comprises of portable devices that assist self-isolated patients in adhering to safe precautionary measures. Government officials are currently using wireless technologies to identify infected people at large gatherings. In this research, we gave an overview of wireless technologies that assisted the general public and healthcare professionals in maintaining effective healthcare services during COVID-19. We also discussed the possible challenges faced by them for effective implementation in day-to-day life. In conclusion, wireless technologies are one of the best techniques in today's age to effectively combat the pandemic.

Comparison of Management and Outcomes of Symptomatic Urolithiasis during the COVID-19 Pandemic to a Comparative Cohort

Objective

To analyze the clinical presentation and outcomes for patients who presented with symptomatic urolithiasis during the initial months of the COVID-19 pandemic.

Methods

We retrospectively reviewed Emergency Department (ED) presentations from a Philadelphia healthcare system for symptomatic urolithiasis between March and June 2020 and compared these with presentations for the same time period from the year prior. Patient demographics, stone characteristics, management, and clinical outcomes were compared between the 2 years.

Results

One hundred and thirty-nine patients presented during 2020 compared to 269 in 2019. There were fewer patients who presented during the initial COVID-19 pandemic surge who had obesity (37.41% vs 49.44%, P = .024), hyperlipidemia (18.71% vs 31.60, P = .006), and asthma (5.76% vs 16.73%, P = .002). Although overall stone characteristics did not differ between the 2 groups, a larger proportion of patients in 2020 presented with an obstructing stone (81.16% vs 64.1%, P = .001). Patients who presented during the COVID-19 pandemic did not have higher rates of infection, acute kidney injury, or complications. Rates of surgical modalities, emergent procedures, and discharges from the ED were similar between the 2 years.

Conclusion

The COVID-19 pandemic initial surge resulted in fewer ED presentations for symptomatic urolithiasis; however, patients who did present were more likely to have obstructing stones, perhaps due to delaying presentation to avoid COVID-19 exposure in the ED. Despite higher rates of obstruction, clinical outcomes and morbidity were similar.

The value of telephone consultations during COVID-19 pandemic. An observational study

BACKGROUND

Many Spanish hospitals converted scheduled in-person visits to telephone visits during the COVID-19 lockdown. There is scarce information about the performance of those visits.

AIM

To compare telephone visits during the COVID-19 lockdown period with previous in-person visits.

DESIGN

Retrospective descriptive study.

METHODS

Telephone visits from 15 March to 31 May 2020 were compared with in-person visits during the same period in 2019.

MAIN MEASURES

The proportions of both groups were compared in term of failure to contact patient, requested diagnostic tests/referrals, discharges, admissions and emergency visits within 30-60 days. A sample of patients, and all participating physicians completed surveys. Z-score test was used (statistical significance P<0.05).

RESULTS

A total of 5602 telephone visits were conducted. In comparison to in-person visits, telephone visits showed higher rates of visit compliance (95.9% vs. 85.2%, P<0.001) and discharges (22.12% vs. 11.82%; P<0.001), and lower number of ancillary tests and referrals. During the 30- and 60-day periods following the telephone visit, a reduction of 52% and 47% in the combined number of emergency department visits and hospital admissions was observed compared to in-person visits (P<0.01). Of the 120 patients surveyed, 95% were satisfied/very satisfied with the telephone visits. Of the 26 physicians, 84.6% considered telephone visits were useful to prioritize patients.

CONCLUSIONS

During health emergencies, previously scheduled outpatient in-person visits can be converted to telephone visits, reducing absenteeism, increasing the rate of discharges and reducing ancillary tests and referrals without increasing the rate of hospital admissions or emergency department visits.

1 year impact of COVID-19 pandemic on Italian dental professionals: a cross-sectional survey

BACKGROUND

The Covid-19 pandemic has disrupted the daily work of the dental professionals, assuming unprecedented economic, managerial, and psychological implications. The aim of this cross-sectional survey was to analyze the extent of the impact linked to the imposed working conditions on the Italian dental team.

METHODS

The survey was administered with a web-based form (Google Forms®) to Italian dentists and hygienists. To be enrolled in the study, participants had to reach the adulthood and agree to sign the privacy policy. The impact of Covid-19 was analyzed through a 27-items questionnaire, which was divided into 4 main domains: personal protective equipment (PPE), operative procedures, secretarial organization, and self-reported quality of life (including elearning appraisal).

RESULTS

A total of 614 between dentists and dental hygienists completed the questionnaire. Compared to the pre-pandemic period, the use of PPE such as face shields, surgical caps and disposable gowns were implemented after the Covid-19 outbreak. Almost the whole interviewed (99.9%) received the Covid-19 vaccine. An increased use of preoperatory mouthwashes and rubber dam was referred during the pandemic, while aerosolization (i.e. ultrasound) was drastically reduced. A certain number of respondents (30% dentists, 27% hygienists) suffered from work-related stresses during the pandemic until they desired to change jobs. E-learning was considered beneficial for the 70% of participants.

CONCLUSIONS

Covid-19 pandemic influenced dental professionals' life, leading to a rearrangement of professional, managerial, and cultural life for both dentists and hygienists even after 1 yr from the outbreak.

The Potential of Mesenchymal Stem Cells for the Treatment of Cytokine Storm due to COVID-19

The outbreak of coronavirus disease 2019 (COVID-19) caused by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) has seriously affected public health and social stability. The main route of the transmission is droplet transmission, where the oral cavity is the most important entry point to the body. Due to both the direct harmful effects of SARS-CoV-2 and disordered immune responses, some COVID-19 patients may progress to acute respiratory distress syndrome or even multiple organ failure. Genetic variants of SARS-CoV-2 have been emerging and circulating around the world. Currently, there is no internationally approved precise treatment for COVID-19. Mesenchymal stem cells (MSCs) can traffic and migrate towards the affected tissue, regulate both the innate and acquired immune systems, and participate in the process of healing. Here, we will discuss and investigate the mechanisms of immune disorder in COVID-19 and the therapeutic activity of MSCs, in particular human gingiva mesenchymal stem cells.

Estimating the viral loads of SARS-CoV-2 in the oral cavity when complicated with periapical lesions

Background

The oral cavity represents a main entrance of the severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2). Angiotensin-converting enzyme 2 (ACE-2), neuropilin-1 (NRP-1), and transmembrane serine protease 2 (TMPRSS2) are essential for the entry of SARS-CoV-2 to the host cells. Both ACE-2 and NRP-1 receptors and TMPRSS2 have been identified in the oral cavity. However, there is limited knowledge about the impact of periapical lesions and their metabolites on the expression of these critical genes. This study aims to measure the impact of periapical lesions and their unique fatty acids (FAs) metabolites on the expression of the aforementioned genes, in addition to interleukin 6 (IL-6) gene and hence SARS-CoV-2 infection loads can be estimated.

Methods

Gene expression of ACE-2, NRP-1, TMPRSS2, and IL-6 was performed in periapical lesions in comparison to healthy oral cavity. Since FAs are important immunomodulators required for the lipid synthesis essential for receptors synthesis and viral replication, comparative FAs profiling was determined in oral lesions and healthy pulp tissues using gas chromatography–mass spectrometry (GC–MS). The effect of major identified and unique FAs was tested on mammalian cells known to express ACE-2, NRP-1, and TMPRSS2 genes.

Results

Gene expression analysis indicated that ACE-2, NRP-1, and TMPRSS2 were significantly upregulated in healthy clinical samples compared to oral lesions, while the reverse was true with IL-6 gene expression. Saturated and monounsaturated FAs were the major identified shared and unique FAs, respectively. Major shared FAs included palmitic, stearic and myristic acids with the highest percentage in the healthy oral cavity, while unique FAs included 17-octadecynoic acid in periapical abscess, petroselinic acid and l-lactic acid in periapical granuloma, and 1-nonadecene in the radicular cyst. Computational prediction showed that the binding affinity of identified FAs to ACE-2, TMPRSS2 and S protein were insignificant. Further, FA-treated mammalian cells showed significant overexpression of ACE-2, NRP-1 and TMPRSS2 genes except with l-lactic acid and oleic acid caused downregulation of NRP-1 gene, while 17-octadecynoic acid caused insignificant effect.

Conclusion

Collectively, a healthy oral cavity is more susceptible to viral infection when compared to that complicated with periapical lesions. FAs play important role in viral infection and their balance can affect the viral loads. Shifting the balance towards higher levels of palmitic, stearic and 1-nonadecene caused significant upregulation of the aforementioned genes and hence higher viral loads. On the other hand, there is a reverse correlation between inflammation and expression of SARS-CoV-2 receptors. Therefore, a mouth preparation that can reduce the levels of palmitic, stearic and 1-nonadecene, while maintaining an immunomodulatory effect can be employed as a future protection strategy against viral infection.

Long-Term Complications of Coronavirus Disease 2019; What the Oral Surgeon Needs To Know

ABSTRACT

Coronavirus disease 2019 (COVID-19) caused by severe acute respiratory syndrome coronavirus 2 manifests mainly as respiratory symptoms. Extrapulmonary manifestations have also been detected and several vital organs may sustain irreversible or long-standing damage. These extrapulmonary manifestations can be detected in cardiovascular, hepatic, renal, and hematologic systems. Maxillofacial surgeons may encounter patients who have recovered from COVID-19 but are still suffering long-term morbidities as a result of this incompletely understood infection. Consequently, they have to be aware of the various systemic complications that may be encountered in these patients as they may interfere with their treatment plan or may necessitate certain modifications and precautions.In this report the authors present the long-standing systemic complications of COVID-19 reported so far, and discuss their implications within the context of maxillofacial surgery with regards to the modifications and precautions in the process of treatment planning.Graphical abstract shows the long-term complications of COVID-19 that may complicate maxillofacial surgical procedures.

Blood cancer care in a resource limited setting during the Covid-19 outbreak; a single center experience from Sri Lanka

BACKGROUND

The Covid-19 pandemic has caused significant morbidity and mortality among patients with cancer. Most countries employed measures to prevent spread of Covid-19 infection which include shielding, quarantine, lockdown, travel restrictions, physical distancing and the use of personal protective equipment. This study was carried out to assess the change in patient attendance and the efficacy of newly implemented strategies to mitigate the impact of Covid-19 on services at the Lanka Hospital Blood Cancer Centre (LHBCC) in Colombo, Sri Lanka.

METHODOLOGY

Telephone consultation, infection control, personal protective measures and emergency admission policy were implemented with the aim of having a Covid-19 free ward and to prevent cross-infections. This descriptive cross-sectional study was conducted with 1399 patient episodes (in-patient care or day-case review). We analysed patients treated as in-patient as well as day-case basis between 01st April 2020 and 31st December 2020.

RESULTS

There were 977 day-case based episodes and 422 in-patient based episodes. There was a 14% drop in episode numbers compared to same period in 2019. There was no cross infection and no patients with Covid-19 related symptoms or positive test results entered the LHBCC during the study period.

CONCLUSION

Services in blood cancer care were maintained to prevent late stage presentation and adverse outcome. Measures implemented to prevent Covid-19 were effective to allow continuation of treatment. This study highlights the importance of implementing strict protocols, clinical screening, use of appropriate personal protective equipment in delivering blood cancer care during the Covid-19 pandemic. This is the only documented study relating to outcome and successful applicability of measures to prevent spread of Covid-19 infection and maintaining services among blood cancer patients in Sri Lanka.

Preliminary Study on Light-Activated Antimicrobial Agents as Photocatalytic Method for Protection of Surfaces with Increased Risk of Infections

Preventing and controlling the spread of multidrug-resistant (MDR) bacteria implicated in healthcare-associated infections is the greatest challenge of the health systems. In recent decades, research has shown the need for passive antibacterial protection of surfaces in order to reduce the microbial load and microbial biofilm development, frequently associated with transmission of infections. The aim of the present study is to analyze the efficiency of photocatalytic antimicrobial protection methods of surfaces using the new photocatalytic paint activated by light in the visible spectrum. The new composition is characterized by a wide range of analytical methods, such as UV-VIS spectroscopy, electron microscopy (SEM), X-ray powder diffraction (PXRD) or X-ray photoelectron spectroscopy (XPS). The photocatalytic activity in the UV-A was compared with the one in the visible light spectrum using an internal method developed on the basis of DIN 52980: 2008-10 standard and ISO 10678—2010 standard. Migration of metal ions in the composition was tested based on SR EN1186-3: 2003 standard. The new photocatalytic antimicrobial method uses a type of photocatalytic paint that is active in the visible spectral range and generates reactive oxygen species with inhibitory effect against all tested microbial strains.

The Clinical Characteristics of Fever-Ward Pediatric Patients with a Definite Epidemiological History During the Early COVID-19 Epidemic Period

OBJECTIVE

The number of children presenting with coronavirus disease 2019 (COVID-19) caused by SARS-CoV-2 infection is increasing, and we aimed to assess the clinical characteristics of pediatric patients with a definite epidemiological history during the early COVID-19 epidemic.

METHODS

Retrospective analysis was performed on the clinical data of children admitted to the fever ward of Xiangyang Central Hospital in Hubei province between January 1, 2020 and March 17, 2020. According to definite epidemiological history, patients with SARS-CoV-2 nucleic acid test (NAT) positive detection were grouped as confirmed cases, and patients with two consecutive negative NATs were grouped as suspected cases. We compared the clinical characteristics of the two groups.

RESULTS

A total of 47 (47/127, 37%) cases had a definite epidemiological history, of which 32 (68.1%) were suspected, with a median age of 5.5 years (interquartile range [IQR]: 0.7-10.3), and 15 (31.9%) were confirmed, with a median age of 9 years (IQR: 4-14). Statistically significant differences in age, family cluster of infection, and numbers of patients with clinical symptoms and fever (P<0.05) were found between the two groups, but no statistically significant differences in leucocyte and lymphocyte counts were observed (P>0.05). Significant differences were found in the computed tomography (CT) manifestation of ground glass opacity (GGO) between the two groups (P<0.05).

CONCLUSION

Children of older age and from family clusters of infection were more easily diagnosed as having COVID-19. GGO changes on chest CT was more likely in confirmed cases. Although obvious clinical manifestations increase our awareness of COVID-19, children without manifestations of fever or cough should not be ignored as they may be asymptomatic carriers.

Air particulate concentration during orthodontic procedures: a pilot study

Background

This study evaluates the particle dispersion involved in dental procedures carried out during orthodontic treatments. Variants such as temperature and relative humidity in the dental cabinet were considered.

Methods

Using a particle counter, a pilot study was conducted, in which 98 consecutive recordings were made during appointments of patients undergoing orthodontic treatments. Temperature, relative humidity and particles present at the beginning (AR) and during the appointment (BR) were recorded. A control record (CR) of temperature, relative humidity and particles present was made before the start of the clinical activity. In addition to conventional statistics, differential descriptive procedures were used to analyse results, and the influence of relative humidity on particle concentration was analysed by statistical modelling with regression equations.

Results

The number of particles present, regardless of their size, was much higher in AR than in CR (p < .001). The same was true for relative humidity and ambient temperature. The relationship between relative humidity and particle number was determined to be exponential.

Limitations of the study

The limitations are associated with sample size, environmental conditions of the room and lack of discrimination among the procedures performed.

Conclusions

This pilot study shows that from the moment a patient enters a dental office, a large number of additional particles are generated. During treatment, the number of particles of 0.3 microns—which have a high capacity to penetrate the respiratory tract-increases. Moreover, a relationship between relative humidity and particle formation is observed. Further studies are needed.

Disinfection Measures during COVID-19 for Dental Operatories

Background:

In the dental health-care setups, the environmental object and surfaces are expected to be infected by the COVID virus wherein definite procedures are performed. Consequently, these objects and surfaces, particularly where COVID-19 patients are being treated, must be appropriately cleaned and sanitized to stop further spread.

Objective:

The present article is intended for providing protocols about the cleaning and disinfection of objects and surfaces in the circumstances of COVID-19 for Dental operatories.

Methods:

Studies evaluating the surface characteristics of the virus as well as effective disinfection measures have been documented.

Results:

Various chemicals in different concentrations have a virocidal effect. The devices introduced include used UV radiation and ozone.

Conclusion:

These changes in dental clinical practice are needed to save humanity by preventing further transmission of disease.

Subjective Smell Assessment as An Office-based Rapid Procedure In COVID-19 Era

A recent history of smell disorder may be a potential predictor for COVID-19. The authors used a subjective olfaction score that was demonstrated on a hard paper-bar. The authors examined 480 patients who were attending the outpatient clinic. Ninety-seven patients (20.2%) demonstrated variable degrees of recent smell disorder. For those patients, lab testing including nasopharyngeal swab for real-time polymerase chain reaction (RT-PCR) was performed. Eighty-eight of them (90.7%) have been confirmed to be COVID-19 positive. Although psychophysical testing is more reliable, subjective assessment of smell is a rapid procedure and can be used as an office-based method for patients’ screening in COVID-19 era. Smell disorder could be an alarming sign for COVID-19 even with absent characteristic symptoms.

Cleft and COVID-19 Pandemic: Controversial Aspects of Social Distancing

ABSTRACT

In the meantime, as COVID-19 has gone pandemic, social distancing has become inevitable; therefore, most in-person visits have been canceled to minimize the spread of the disease. This will greatly impact cleft palate patients as it will limit their chance to receive timely care and have persistent follow-up, and that could in turn delay its management so significantly that it could cause much more considerable complications. To mitigate the issue, it seems necessary to start integrating modern-day technologies into the everyday practice of physicians and to benefit from the opportunities it provides. Much of medical decision making is cognitive, and telemedicine can provide easy access to specialists who are not immediately available. With wide internet access, this task is more than feasible. Telemedicine and other modern facilities are very promising platforms that could fill the gap that has been made by social distancing. We tried to address some of these issues as well as give recommendations for possible solutions to each of them.

Management of Maxillofacial Trauma in Attempt Suicide Patients During COVID-19 Pandemic

The maxillofacial surgeon trained well to face the surgical challenges. In case of dealing with self-inflicted trauma, the surgeon must face the surgical as well as the psychological status of the patients. Five patients received in the emergency room suffering from maxillofacial trauma resulted from suicidal attempts. Unfortunately, 1 patient died, the other patients managed by providing surgical and psychological support. The cornerstone of managing such type of trauma needs appropriate communication between the family, surgical team, and the psychiatric.

Is Tele-Dentistry an Effective Approach for Patient Follow-up in Maxillofacial Surgery

PURPOSE

To explore the feasibility and diagnostic accuracy of the tele-dentistry for the follow-up of different diagnostic groups of Turkish patients in maxillofacial surgery.

MATERIALS AND METHODS

In this study, follow-up patients were allocated to four groups as dental implant, minor surgical procedure, infection-medication-related osteonecrosis of the jaws (MRONJ) and temporomandibular joint disorder (TMD). In all groups, remote examination via video call and subsequently face-to-face clinic examination were performed. The quality and accuracy of the video call were scored by the same investigator. Also, patient satisfaction regarding the video call was evaluated with a questionnaire.

RESULTS

Twenty-one patients (12 females, 9 males) between 18 and 71 years (38.90 ± 17.88) participated in the study. A strong preference of 71% and 95% toward video call by patients was seen in the questionnaires performed after video call and face-to-face examination, respectively. Regarding the rating of the clinician, no significant differences were found between groups in terms of the quality and accuracy of video call (p ≥ 0.05).

CONCLUSION

Remote follow up of diagnostic groups which can benefit from tele-dentistry pose a promising remedy that is reliable as in-person visits and also can reduce the clinical visits in routine clinical practice.

Telemedicine in Peru as a Result of the COVID-19 Pandemic: Perspective from a Country with Limited Internet Access

The COVID-19 pandemic contributed to the worldwide implementation of telemedicine because of the need for medical care for patients, especially those with chronic diseases. This perspective paper presents the current situation of telemedicine in Peru, showing advances in regulation, cases of successful implementation, and the current challenges. Access to health should be available to all, and more efforts need to be implemented to offer access to the internet to achieve high-quality telemedicine to all the vulnerable groups in Peru.

Evaluation of Nasal Mucociliary Clearance Time in COVID-19 Patients

Background:

Coronavirus Disease 2019 (COVID-19) is a viral pandemic emerging in East Asia and spreading rapidly to the rest of the world and continuing in our country. The number of studies examining the symptoms of the otolaryngology system and organs in COVID-19 patients is limited. The purpose of this study is to show whether COVID-19 infections cause any changes in nasal physiology in adult patients by measuring the mucociliary clearance (MCC) time with the saccharin test.

Methods:

One hundred one patients with laboratory-confirmed COVID-19 infection (group 1, n = 42 smokers and group 2, n = 59 nonsmokers) and 87 individuals without COVID-19 infection as the control group (group 3, n = 33 smokers and group 4, n = 54 nonsmokers) were included in the study. A saccharin test was used to evaluate the nasal MCC time.

Results:

Mucociliary clearance test averages of the groups were determined as 473.571 ± 263.684, 442.966 ± 228.463, 468.333 ± 267.367, 412.629 ± 192.179 seconds, respectively. When the test durations were examined, the group with the most prolonged MCC duration was determined as the smoking COVID (+) patient group (473.571 ± 263.684 seconds). The second group, with the most prolonged MCC duration, was determined as the smoking control group (468.333 ± 267.367 seconds). No statistically significant difference was found in intergroup mucociliary clearance time (P = 0.760).

Conclusion:

Although the authors found that smoking and viral infections prolong the MCC duration in our study, they did not find a statistically significant difference between the groups in terms of MCC duration.

General Practice in the Time of COVID-19: A Mixed-Methods Service Evaluation of a Primary Care COVID-19 Service

Primary care coronavirus disease 2019 (COVID-19) clinics were rapidly introduced across the UK to review potentially infectious patients. Evaluation of these services is needed to guide future implementation. This mixed-methods study evaluates patient demographics, clinical presentation, co-morbidities, service usage, and outcomes for the Islington COVID-19 service (London, UK) and from April to May 2020 and thematically analyses survey responses from 29 service clinicians and 41 GP referrers on their service experience. Of the 237 patients booked into the service, a significant number of referrals (n = 91; 38.6%) were made after the presumed infectious period of 14 days. Almost half of all adult referrals (49%) were dealt with remotely (via telephone/video consultation +/− remote oxygen saturation monitoring). The service was perceived to provide a safe way to see patients; it developed local expertise, learning, and empowerment; and it was a positive teamworking experience. These findings suggest that the management of many patients with COVID-19 symptoms is possible in routine general practice with minimal risk through the implementation of remote consultation methods and in patients who present after the post-infectious period. Additionally, the use of remote saturation monitoring and local GP COVID-19 “experts” can support practices to manage COVID-19 patients. Future primary care COVID-19 services should act as empowerment tools to assist GPs to safely manage their own patients and provide support for GPs in this process.

The Importance of Atmospheric Microbial Contamination Control in Dental Offices: Raised Awareness Caused by the SARS-CoV-2 Pandemic

Background: In the context of the Sars-CoV-2 pandemic that started in 2020, more attention is being paid to the air quality in medical offices. The medical, economic and social implications of this crisis are unprecedented. Dental offices, particularly, were significantly affected by this pandemic due to the high exposure of dental workers, limited availability of personal protective equipment (PPE) and serious financial problems. Methods: Four different procedures were compared regarding their effectiveness in air contamination reduction, both from a biological point of view and from a management point of view: Fogging, Ultraviolet C (UVC) lamps, UVC air circulation units and natural ventilation. A total of 56 Petri dishes were used to evaluate air contamination. Results: All four procedures offered good results but the decontamination time and overall effect varied depending on the chosen method. Fogging was the only method that managed to remove all the identifiable pathogens. Conclusions: Fogging proved to be superior from a medical point of view, while the UVC air circulation unit proved to be more efficient from a management point of view.

The Professional and Psycho-Emotional Impact of the COVID-19 Pandemic on Medical Care-A Romanian GPs' Perspective

The aim of this study was to assess the psycho-emotional impact and the adjustment degree of Romanian general practitioners (GPs) in the coronavirus disease 2019 (COVID-19) pandemic context. With a cross-sectional design, the study included 677 GPs to whom a validated questionnaire based on different items targeting three factors was sent: burden of prevention, presence of stress symptoms, and adjustment to pandemic. The burden of prevention and the adjustment effort to the pandemic were felt significantly more by female doctors and by GPs working in associated offices. The case definition quality, the support received, the professional life changes, and the stress symptoms proved to be the main predictors for the adjustment to pandemic. The adjustment measurement questionnaire can be used in further studies to identify the most supportive public health practices in difficult epidemiological contexts.

Infection control strategy and primary care assistance in Campania region during the national lockdown due to COVID-19 outbreak: the experience of two tertiary emergency centers

Background

COVID-19 pandemic has markedly affected emergency care, due to sudden limitation of health care capacity by general practitioners (GP) and urgent need for infection control strategies. We evaluated the activity of the Emergency Department (ED) during the national lockdown (March 8–April 30), as well as the outcomes of our infection control strategy.

Results

Despite a reduction in access by one fifth, a proportion of febrile patients comparable to 2019 was seen (829/2492, 33.3% vs 4580/13.342, 34.3%, p = 0.3). Diagnostic swab for COVID-19 was performed in 25% of patients, especially in subjects with co-morbidities or multiple access. Six infected cases were identified, all presenting with febrile disease. Only two positive patients fulfilled the criteria for diagnostic swab provided by the Italian Health Authorities, because of close contact with suspected or confirmed cases.

The rate of admission for febrile or respiratory conditions was higher than the same period of 2019 (33.4% vs 25.9%, p < 0.0001). None of the 105 health-care professionals working during the study time lapse exhibited anti-SARS-CoV-2 seroconversion. Among the 589 patients with information available, 54.9% declared no medical consultation at all prior to coming to ED, while only 40 (of which 27 with fever) had been examined by their GP before coming to ED. Nevertheless, 35.6% of the cases were already taking medications. None of the 9 patients requiring intensive care reported recent pediatric consultation, despite symptoms duration up to 30 days.

Conclusion

Our results provide evidence that the reduced capacity of primary care facilities during the national lockdown may have caused a high rate of self-medication as well as a delayed provision of care in some patients. Identification of pediatric patients affected with SARS-CoV-2 infection remains a challenge because of the absence of reliable predictive factors. Finally, the use of specific triage centers, with dedicated pathways to diagnose SARS-CoV-2 infection, trace contacts and allow adequate care after swabs, is effective in preventing spreading of the infection.

Olfactory and Gustatory Dysfunctions in COVID-19 Patients: From a Different Perspective

The prevalence of sensory disorders (smell and/or taste) in affected patients has shown a high variability of 5% to 98% during the COVID-19 outbreak, depending on the methodology, country, and study. Loss of smell and taste occurring in COVID-19 cases are now recognized by the international scientific community as being among the main symptoms of the disease. This study investigates loss of smell and taste in outpatients and hospitalized patients with laboratory-confirmed COVID-19 infection.

Impact of Transmission Control Measures on the Epidemiology of Maxillofacial Injuries in Wuhan City During the COVID-19 Epidemic

ABSTRACT

In December 2019, a novel coronavirus (severe acute respiratory syndrome coronavirus 2) emerged in Wuhan City. The present study aimed to assess the demographic variables, causes, and patterns of maxillofacial injuries managed at a teaching hospital in Wuhan City during the transmission control measures in the coronavirus disease 2019 (COVID-19) epidemic. In this retrospective study, all patients treated for maxillofacial injuries in the hospital between January 23 and April 7 (2019 and 2020) were involved. Epidemiologic information, including the number of patients, gender, age, etiology, time since injury to the clinic visit, and type of maxillofacial injuries, was recorded. Data of the 2 periods (2019 and 2020) were compared and analyzed. A total of 337 patients had maxillofacial injuries at the 2-time intervals: 74 in 2020 and 263 in 2019. The characteristics of maxillofacial injuries had changes during the transmission control measures in the COVID-19 epidemic, which included the number of patients, gender, age, etiology, time since injury to the clinic visit, and type of maxillofacial injuries. The transmission control measures during the COVID-19 epidemic had a significant impact on the epidemiology of maxillofacial injuries in Wuhan City.

Alsalhani A, Alqhtani NR, Bin Nabhan A, Alenzi A, Alrafedah A. COVID-19-Awareness and Practice of Dentists in Saudi Arabia

Dental professionals have a major role in the fight against the spread and transmission of COVID-19. This study aimed to evaluate awareness and practice of dentists in Saudi Arabia regarding COVID-19 and the utilization of infection control methods. A 24-item questionnaire was developed and distributed through social media to 627 dentists working in Saudi Arabia. 177 questionnaires were completed (28.2% response rate). Most dentists were aware about the transmission, incubation time and main clinical symptoms of COVID-19. Almost 83% of the respondents appreciate the risk of droplets, aerosols and airborne particles in transmission of COVID-19 in the dental clinic. Among the common practices of participants are measuring patient’s body temperature before undertaking a dental treatment (88.7%), cleaning the environmental surfaces at the dental clinic after each patient (91.5%) and restriction of dental treatment to emergency cases (82.5%). It seems that practicing dentists in Saudi Arabia are fairly aware about COVID-19. The practices of the surveyed dentists appear to be mostly consistent with the current guidelines and recommendations for infection control of COVID-19 in the dental clinic. Some drawbacks in knowledge and a number of inappropriate practices can be identified and require the attention of health authorities.

Assessment of trends and clinical presentation in the emergency department of patients with renal colic during the COVID-19 pandemic era

Introduction

We hypothesized that the recent COVID-19 pandemic may lead to a delay in renal colic patients presenting to the Emergency Department due to the fear of getting infected. This delay may lead to a more severe clinical condition at presentation with possible complications for the patients.

Material and methods

Retrospective review of data collected from three institutions from Spain and Italy. Patients who presented to Emergency Department with unilateral or bilateral renal colic caused by imaging confirmed urolithiasis during the 45 days before and after each national lockdown were included. Data collected included patients’ demographics, biochemical urine and blood tests, radiological tests, signs, symptoms and the therapeutic management. Analysis was performed between two groups, Group A: patients presenting prior to the national lockdown date; and Group B: patients presenting after the national lockdown date.

Results

A total of 397 patients presented to Emergency Department with radiology confirmed urolithiasis and were included in the study. The number of patients presenting to Emergency Department with renal/ureteric colic was 285 (71.8%) patients in Group A and 112 (28.2%) patients in Group B (p < 0.001). The number of patients reporting a delay in presentation was 135 (47.4%) in Group A and 63 (56.3%) in Group B (p = 0.11). At presentation, there were no statistical differences between Group A and Group B regarding the serum creatinine level, C reactive protein, white blood cell count, fever, oliguria, flank pain and hydronephrosis. In addition, no significant differences were observed with the length of stay, Urology department admission requirement and type of therapy.

Conclusion

Data from our study showed a significant reduction in presentations to Emergency Department for renal colic after the lockdown in Spain and Italy. However, we did not find any significant difference with the length of stay, Urology department admission requirement and type of therapy.

Coronavirus Disease 2019 Coexistence in the Daily Practice

The purpose of the present narrative review was to evaluate and discuss the actual available information regarding coronavirus disease 2019 and dental practice, and to share recommendations with the intent to help dentists in providing a safe and healthful workplace during pandemic. A step-by-step workflow is presented including prevention and measures to reduce risk for cross infections before, during, and after the dental treatments. Individualization of different risk-level zones and the establishment of a team-based chain control is also presented. The present manuscript may offer deeper knowledge and discussion regarding recommended procedures aimed to reduce risk for dental health care workers contamination and cross infections. Within these, infection prevention in dental settings, respect of general rules, containment measures, proper use of the personal protective equipments (PPE), and well-organized chain control of all the staff, with definition of risk zones and specific responsibility could be an adjunctive but important step to control the spread of the disease.

Dental Office Prevention of Coronavirus Infection

Coronavirus disease is now spreading in different countries of the world. The alarmism created through the media also creates confusion in people about virus spreading. The health care environments among which the dental practice could be places of spread of the virus, especially places where patients with systemic pathology could be exposed to this. The purpose of this article is to clarify coronavirus disease 2019 and its management in the dental practice. Only by following the normal guidelines on disinfection and sterilization of environments and operators, with some additional rules on the management of patients in the waiting room, it is possible to limit this risk. Limiting the risk of spreading the virus is one of the keys to its eradication.

Assessment of Smell and Taste Disorders in COVID-19: A Cross-sectional Study

BACKGROUND

It has been reported worldwide that patients with a diagnosis of COVID-19 usually suffer a loss of smell and taste. In this study, we aimed to evaluate the relationship between the severity of the disease and the loss of smell and taste. In addition, we evaluated patients' smell and taste functions after recovery.

METHODS

Between March and May 2020, 418 patients diagnosed with COVID-19 were divided into 3 groups: home-quarantined, hospitalized, and intensive care patients. The disease, smell, and taste functions of patients were evaluated with visual analog scores before diagnosis of COVID-19, during the disease, and fourth week after recovery. The types of smell loss and types of taste flavor loss occurring during the disease were questioned.

RESULTS

In all 3 groups, changes in smell and taste loss during the disease were statistically detected (P = 0.001). The smell loss rates determined in groups 1 to 3 were 45%, 43.7%, and 31.2%, respectively. The taste loss rates determined in groups 1 to 3were 46.6%, 32.1%, and 31.2% respectively. The rate of patients with a total recovery of smell loss in groups 1 to 3 were 95.5%, 93.7%, and 100%, respectively (P = 0.768). The rate of patients with a total recovery of taste loss in groups 1 to 3 were 97.1%, 91.4%, and 100%, respectively (P = 0.423).

CONCLUSION

COVID-19 causes significant loss of smell and taste in patients. The loss of smell and taste does not correlate with the severity of COVID-19 disease. The loss of smell and taste improves at a high rate after the disease.

Have There Been any Changes in the Epidemiology and Etiology of Maxillofacial Trauma During the COVID-19 Pandemic? An Italian Multicenter Study

Supplemental Digital Content is available in the text

Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) has had a significant impact on people's behavior. The aim of this study has been to evaluate how the SARS-CoV-2 pandemic has impacted the incidence and the features of maxillofacial fractures presented at 6 Italian tertiary centers. Clinical records of all the patients diagnosed for facial fractures between February 23 and May 23, 2019 and 2020 were retrospectively reviewed. Any differences in patient number and characteristics and fracture etiology and site between the 2 groups were then statistically analyzed.

There has been a 69.1% decrease in the number of incoming patients during the pandemic. The number of foreign patients has decreased significantly (23.3% versus 9.6%, P = 0.011) while the average age has increased (38.6 versus 45.6 years old, P = 0.01). Specific statistical significant differences for accidental falls (31.8% versus 50.1%, P = 0.005) and sports injuries (16.9% versus 1.4%, P < 0.001) were found. Concerning fracture sites, significant differences have been found in relation to nasal (22.5% versus 11.4%, P = 0.009) and frontal sinus (0.9% versus 4.4%, P = 0.037) fractures. In conclusion, SARS-CoV-2 pandemic has significantly changed the epidemiology and the etiology of facial traumas.

Recommendations, Practices and Infrastructural Model for the Dental Radiology Set-up in Clinical and Academic Institutions in the COVID-19 Era

The pandemic of Coronavirus disease (COVID-19) has emerged as a global catastrophe that is plaguing mankind. In the past eight months since the world discovered about COVID-19, we learned a lot about server acute respiratory syndrome coronavirus 2 (SARS CoV-2) and perhaps there is much more to discover and understand about the virus. With the current understanding of the disease, we assume it will remain in an active state of transmission and progression among the community for a long time. Thus, it is advisable to adopt the disease's prevention protocol in our daily and work routine. During this pandemic patient requiring dental treatment cannot be neglected and the role of dental imaging is crucial in delivering treatment. Hence, this article attempts to provide an evidence-based compilation about the mode of transmission and clinical features of COVID-19. It also throws light on the potential source of disease transmission in the dental radiology setting. In addition, it suggests preventive measures to curb the infection and infrastructural model of the clinical setting that will assist in achieving control over the disease transmission. This article intends to project a strategy about protocols, infrastructure, and daily activities in a dental radiology office that institutions can adopt with modifications according to their local scenario.
