2019 novel coronavirus disease epidemic: skin protection for healthcare workers must not be ignored

N95 respirators alter facial skin physiological functions and lipidome composition in health care personnel

BACKGROUND

During the coronavirus disease 2019 pandemic, wearing medical respirators and masks was essential to prevent transmission.

OBJECTIVE

To quantify the effects of N95 mask usage by measuring facial skin biophysical characteristics and changes in the lipidome.

METHODS

Sixty healthy volunteers wore N95 respirators for 3 or 6 h. Facial images were acquired and physiological parameters were measured in specific facial areas, before and after mask-wearing. Lipidome analysis was also performed.

RESULTS

After N95 respirator usage, facial erythema was observed in both the 3 and 6 h groups. Both sebum secretion and trans-epidermal water loss increased significantly in mask-covered cheeks and chins after 6 h of mask wearing compared with before mask wearing (p < 0.05). Principal component analysis revealed significant differences in lipid composition after mask wearing compared with before. The ceramide subclass NS exhibited a positive correlation with stratum corneum hydration, whereas the AP subclass was negatively correlated with trans-epidermal water loss in the 6 h group.

CONCLUSION

Prolonged wear of N95 respirators may impair facial skin function and alter lipidome composition.

Combining protection with skin health: In vivo studies of an innovative gelatin/tannic acid-based hydrogel patch to prevent PPE-related skin lesions

The prolonged use of Personal Protective Equipment (PPE) can lead to skin problems due to persistent pressure, friction, and tension. This issue has prompted the exploration of solutions to protect the skin while maintaining the effectiveness of the PPE. This study aimed to evaluate the in vivo effectiveness of a gelatin/tannic acid-based hydrogel patch positioned beneath a mask to alleviate skin damage resulting from mask-wearing. To understand the pressure exerted by PPE, in vitro tests were conducted to measure the tensile strength of three types of facial masks. The FFP2 masks exhibited the highest tensile strength and were selected for subsequent in vivo biometric investigations. Biometric parameters were evaluated using the Flir E50bx® thermographic camera, Corneometer®, MoistureMap®, Sebumeter®, Tewameter®, and VISIA® systems. The results showed that when the hydrogel patch was used under the mask, there were no significant differences in facial skin temperature, sebum levels, or TEWL values (p > 0.05). However, a statistically significant increase in skin hydration and a decrease in frontal redness (p < 0.05) were observed. Consumer acceptance was assessed through sensory analysis questionnaires. In summary, the observed attenuation of physiological changes in the facial area and the positive consumer feedback suggest that this polymeric film-forming system is a simple yet effective solution to prevent PPE use-related skin issues.

Prevention of skin lesions caused by the use of protective face masks by an innovative gelatin-based hydrogel patch: design and in vitro studies

The recent Covid-19 pandemics led to the increased use of facial masks, which can cause skin lesions due to continuous pressure, tension and friction forces on the skin. A preventive approach is the inclusion of dressings between the face and the mask. However, there are still uncertainties about the protective effect of dressings and whether their use compromises the efficiency of masks. The current study aimed to develop and test the efficacy of a gelatin-based hydrogel patch to be placed between the mask and the facial area. Design of Experiment with a Quality by Design approach tools were used in the patch development and in vitro characterization was performed through rheological evaluation, ATR-FTIR and molecular docking studies. Furthermore, tribology studies were performed to test the patch performance. The results showed that the addition of excipients enhanced gelation temperature, elasticity and adhesiveness parameters. The interactions between excipients were confirmed by ATR-FTIR and molecular docking. The tribology assay revealed similar friction values at room and physiological temperature, and when testing different skin types. In conclusion, the physical properties and the performance evaluation reported in this study indicate that this innovative film-forming system can be used to prevent skin lesions caused by the continuous use of protective masks.

Physical problems of prolonged use of personal protective equipment during the COVID-19 pandemic: A scoping review

Background

It is widely believed that using personal protective equipment (PPE) provides high levels of protection for healthcare workers (HCWs) in the fight against coronavirus disease (COVID‐19). However, the long‐term use of PPE is inconvenient for HCWs and may cause physical discomfort. These factors could result in poor compliance and disrupt the health and safety of HCWs, which may negatively affect the patient's safety.

Objective

This study aimed to investigate the literature for the purpose of collecting convincing evidence of HCWs' physical problems associated with PPE use during the COVID‐19 pandemic.

Methods

This scoping review was conducted using PubMed, Embase, ProQuest, Science Direct, Springer, Biomed Central, and Google Scholar to identify the related literature.

Results

HCWs have experienced various physical disorders including skin, respiratory, musculoskeletal, nervous, urinary, and circulatory system problems that are associated with PPE in various body systems. Among these, skin problems were the most frequent physical problems.

Conclusions

The literature demonstrated the adverse impacts of using PPE on HCWs. Therefore, healthcare policymakers should take the appropriate measures to improve the work environment during the COVID‐19 pandemic, which could consequently prevent and mitigate the adverse effects of using PPE.

Indirect consequences of coronavirus disease 2019: Skin lesions caused by the frequent hand sanitation and use of personal protective equipment and strategies for their prevention

The coronavirus disease 2019 (COVID‐19) pandemic caused by the severe acute respiratory syndrome coronavirus 2 (SARS‐CoV‐2) enforced the use of hand sanitation and of personal protective equipment, such as masks and visors, especially by health‐care professionals, but also by the general public. However, frequent hand sanitation and the prolonged and continuous use of personal protective equipment are responsible for constant frictional and pressure forces on skin causing lesions, the most reported being acne, facial itching, dryness, and rash. Thus, it is important to find measures to prevent skin lesions, in order to improve the quality of life of health‐care professionals and of the general public. This article gathers the current information regarding measures to prevent human to human transmission of COVID‐19, reviews the most common skin lesions caused by the use of hand sanitizers and different types of personal protective equipment, and the possible preventive measures that can be used on a daily basis to minimize the risk of developing skin‐related pathologies. Daily skin care routines and the incorporation of a dressing between the skin and the personal protective equipment to serve as a protective barrier are some of the applied measures. Moisturizers and dressings improve the skin's ability to respond to constant aggressions. Lastly, the need for additional studies to evaluate the lubrication properties of different types of dressings is discussed. The understanding of what kind of dressing is more suitable to prevent pressure injuries is crucial to promote healthy skin and wellbeing during pandemic times.

P2/N95 respirators & surgical masks to prevent SARS-CoV-2 infection: Effectiveness & adverse effects

BACKGROUND

Millions of people have acquired and died from SARS-CoV-2 infection during the COVID-19 pandemic. Healthcare workers (HCWs) are required to wear personal protective equipment (PPE), including surgical masks and P2/N95 respirators, to prevent infection while treating patients. However, the comparative effectiveness of respirators and masks in preventing SARS-CoV-2 infection and the likelihood of experiencing adverse events (AEs) with wear are unclear.

METHODS

Searches were carried out in PubMed, Europe PMC and the Cochrane COVID-19 Study Register to 14 June 2021. A systematic review of comparative epidemiological studies examining SARS-CoV-2 infection or AE incidence in HCWs wearing P2/N95 (or equivalent) respirators and surgical masks was performed. Article screening, risk of bias assessment and data extraction were duplicated. Meta-analysis of extracted data was carried out in RevMan.

RESULTS

Twenty-one studies were included, with most having high risk of bias. There was no statistically significant difference in respirator or surgical mask effectiveness in preventing SARS-CoV-2 infection (OR 0.85, [95%CI 0.72, 1.01]). Healthcare workers experienced significantly more headaches (OR 2.62, [95%CI 1.18, 5.81]), respiratory distress (OR 4.21, [95%CI 1.46, 12.13]), facial irritation (OR 1.80, [95%CI 1.03, 3.14]) and pressure-related injuries (OR 4.39, [95%CI 2.37, 8.15]) when wearing respirators compared to surgical masks.

CONCLUSION

The existing epidemiological evidence does not enable definitive assessment of the effectiveness of respirators compared to surgical masks in preventing infection. Healthcare workers wearing respirators may be more likely to experience AEs. Effective mitigation strategies are important to ensure the uptake and correct use of respirators by HCWs.

The Emotional Impact of Maskne in the Era of COVID-19: A Commentary on the Future of a Multi-Modality Approach

Over the past two years, the world has experienced the destructive effects of the SARS-CoV-2 pandemic, better known as COVID-19. The use of surgical face masks was declared necessary by many governments around the world to protect citizens from catching the rapidly spreading virus. Albeit surgical masks contributing to stopping the spread of SARS-CoV-2, many people have reported rashes closely resembling acne on their chins ever since wearing face masks became mandatory. This article studies the acne that results from masks worn to prevent the transmission of the SARS-CoV-2. Acne due to the wearing of masks (“Maskne”) is a new challenge that has affected the population and can decay the mental health of societies and individuals. The exploration of the mental and physical health effects of “Maskne” help us to form treatments that emphasize the association of improving mental health to decrease acne and enhancing quality of life.

Personal protective equipment and adverse dermatological reactions among healthcare workers: Survey observations from the COVID-19 pandemic

The pandemic of the 2019 novel coronavirus disease (COVID-19) has caused an unprecedented mobilization of the United States' healthcare workforce. In addition to working extended hours under increased duress, healthcare professionals (HCP) of all stations have been making use of various types of personal protective equipment (PPE) with greatly increased frequency and duration. Current data regarding adverse skin reactions as a possible consequence of PPE use are, particularly in the United States, largely insufficient for policy-makers to make informed decisions regarding daily PPE use among HCP.The research vehicle employed by this study is a cross-sectional 25-item survey distributed via email to workers currently employed by a five-hospital system in southcentral Kentucky. This survey was used to collect information from hospital workers of all professional roles about their experiences during the COVID-19 pandemic, focusing on reports of adverse dermatological reactions and associated risk factors.Out of 879 respondents, 54.4% reported some type of skin irritation reaction. Skin irritation was significantly more prevalent among medical and medical support staff than non-medical hospital workers, with the highest prevalence among Certified Nurse Assistant (CNAs). Among clinical workers, those in dedicated COVID-19 units reported the highest prevalence of adverse skin reaction. The most common complaint was dryness/scaling of the skin (306 out of 439, 69.7%), and the most common location was the facial cheeks (305 out of 516, 59.1%). Among those who reported skin irritation, the average self-reported severity of skin reaction (on a scale of 1-5) was 2.00 ± 0.05, and the mean total days of skin reaction per month was 11.70 ± 0.39 days. Total days of irritation per month was found to be significantly related to "total days of PPE use per month," "hours of PPE use per day," "frequency of hand washing," and "use of disinfecting UV irradiation." Severity of skin reaction was found to be significantly related to "hours per day of PPE use," "consecutive days of PPE use," and "female sex."Clinical workers that put in the most face-to-face time with patients, and those in dedicated COVID-19 units, had the highest risk of adverse skin reaction. Overall, skin reactions were found to be mild, even in those hospital workers with the heaviest PPE use. Because the widespread and consistent use of facial masks in public settings has become a key tool in our protracted struggle with SARS-CoV-2, these findings may help to ameliorate concerns that everyday facial mask and/or other PPE usage contributes to significant dermatologic morbidity among both medical professionals and public citizens.

Assessment of hand hygiene strategies on skin barrier function during COVID-19 pandemic: a randomized clinical trial

INTRODUCTION

COVID-19 has increased the frequency of hand washing. There is scarce evidence regarding the impact of different hand hygiene procedures on skin barrier function in clinical practice.

OBJECTIVE

To compare the impact on skin barrier function of different hand hygiene measures in health care workers in daily practice.

METHODS

A randomized controlled clinical trial was conducted. Participants were randomized to sanitize their hands with water and soap, alcohol-based hand sanitizers (ABHS) or disinfectant wipes during their 8-hour work-shift. Epidermal barrier functional parameters, like transepidermal water loss (TEWL), and the microbial load were assessed before and immediately after the workday. Tolerance and acceptability of each product were recorded after work.

RESULTS

Sixty-two participants were included and 20, 21 and 21 were randomized respectively to use water and soap, ABHS and disinfectant wipes. After the 8-hour shift, TEWL increase was higher with disinfectant wipes than with soaps or ABHS (+5.45vs + 3.87vs-1.46 g·h^-1 ·m^-2 respectively, P = .023). Bacteria and fungi colony-forming unit (CFU) count reduction was lower for water and soap group than for ABHS and disinfectant wipes. Disinfectant wipes were considered more difficult to use (P = .013) compared to water and soap and ABHS.

CONCLUSION

Daily hand hygiene with ABHS showed the lowest rates of skin barrier disruption and the highest reduction of CFU. This article is protected by copyright. All rights reserved.

Association of Acne with Face Mask in Healthcare Workers Amidst the COVID-19 Outbreak in Karachi, Pakistan

Background

In the wake of coronavirus (COVID-19) global alert, people have begun to practice safety measures in order to reduce the exposure to life-threatening disease. The largest at risk population is undoubtedly the frontline healthcare workers (HCWs) who are using personal protective equipment (PPE), essentially face masks, to battle against this deadly virus. This study was conducted with the prime intention to reveal an association between face mask and acne and measure the prevalence of acne amongst HCWs amidst COVID-19 outbreak in Karachi. Furthermore, this study aimed to identify the type of mask generating acne, locate the common sites, assess the severity and establish an association of mask use with the skin type.

Methods

This cross-sectional study was carried out at Medicare Cardiac and General Hospital, Jinnah Medical College Hospital, Jinnah Postgraduate Medical Centre and Jamal Noor Hospital located in Karachi, Pakistan. A total of 348 HCWs were interviewed, of which only 193 met the inclusion criteria. All information was recorded on a predesigned proforma and analyzed using SPSS 25.0.

Results

Among 193 participants, acne was prevalent in 103 (53.4%) participants with maximum cases reported in female HCWs, and in doctors (p<0.05). Out of 73 HCWs using N-95 masks, 46 (44.7%) developed acne, with a p-value of 0.036. Skin type and past history of acne also yielded statistically significant results. Among all the skin types, HCWs with oily skin (64, 62.1%) were prone to face resurgence of acne or new-onset acne. The most common sites of eruption of acne were along the cheeks (45.1%) followed by the nose (40.9%). Majority of the population suffered from mild acne. Moderate and severe acne eruption was particularly observed in those wearing N-95 and surgical masks.

Conclusion

The use of face masks is associated with high rates of acne eruption. Disseminating the guidelines and indications of World Health Organization (WHO) regarding proper use of mask, encouraging awareness among HCWs and following proper doffing and donning protocol as endorsed by Centers for Disease Control and Prevention (CDC) will possibly minimize the adverse reactions.

Dermatological manifestations associated with COVID-19: A comprehensive review of the current knowledge

Coronavirus disease 2019 (COVID-19) caused by severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2) has become a significant health problem globally. The virus has spread widely and become a global pandemic. The pathophysiology for SARS-CoV-2 has not been explained clearly. It has been associated with several multiorgan symptoms, among which its dermatological manifestations are of great interest. Primarily, there has been no report of skin features among COVID-19 patients. Nevertheless, recently there have been several reports regarding COVID-19 patients who presented with cutaneous manifestations. In the current review, we focus on the various cutaneous manifestations of COVID-19 infection.

Occupational Dermatoses Related to Personal Protective Equipment Used During the COVID-19 Pandemic

The recent coronavirus disease 2019 (COVID-19) pandemic has led to the dramatic increase in use of personal protective equipment (PPE) among health care providers and the general public. Herein the authors discuss the various occupational dermatoses including allergic and irritant contact dermatitis, acne, seborrheic dermatitis, and rosacea related to frequent handwashing, disinfecting of surfaces, and prolonged wear of various PPE including face masks, gloves, and gowns. The authors provide an overview of published PPE-associated occupational dermatoses during the COVID-19 pandemic and also discuss prevention strategies and treatment options to help patients with these complaints.

How dermatology has changed in the COVID-19 pandemic

The emergence of the coronavirus disease 2019 pandemic has led to a change in the whole world order. The key actors and occupational groups most at risk during this period have been health care professionals. In this pandemic, we, as dermatologists, also have many responsibilities regarding patients, ourselves, and society. Dermatologists have to protect themselves, their families, and their patients while working in pandemic services and outpatient clinics, as well as in their practices. One of their roles is to inform the public about protective measures for cutaneous side effects associated with the intensive use of disinfectants and long-term use of masks. In hospitals, only emergency patients had been admitted for treatment in all units during the pandemic, and elective operations and procedures were delayed. In this context, it is very important to determine what procedures will be carried out during this period in the follow up and treatment of chronic dermatologic diseases, as well as what interventional and cosmetic procedures may performed. Guidelines issued by various medical societies have made valuable contributions. The benefits and associated issues of teledermatology have pros and cons. Finally, one of the issues to ponder in the long term seems to be how we should pursue online education.

Global impact on dermatology practice due to the COVID-19 pandemic

This contribution focuses on the effects of coronavirus disease 2019 (COVID-19) on dermatology practice. We discuss the impact on practice volume and procedures and on the considerable increase in teledermatology use. We also describe the important roles that dermatologists have played in enhancing infection prevention and on the frontline. During the crisis, dermatologists have faced the challenge of a shortage of resources, such as personal protective equipment, in the health care system. In addition, they have been involved in managing cutaneous manifestations related to COVID-19 and occupational disease caused by personal protective equipment. Dermatologists have made a diligent effort to identify melanoma and to ensure the treatment of high-risk skin cancers. Safety guidelines have been suggested to minimize the potential risks associated with the systemic use of immunosuppressant agents and immunomodulators in patients with severe inflammatory skin disease during the pandemic. Finally, social distancing necessitated that dermatology conferences take place virtually and teaching via e-learning increased.

Occupational facial dermatoses related to mask use in healthcare professionals

Background

Mask use can lead to facial dermatoses due to factors, such as hyperhydration, seborrhea, high humidity caused by sweating, and the occlusive effect of the mask.

Aim

We investigated mask‐related facial dermatoses in healthcare personnel who, since the beginning of the COVID‐19 pandemic, had to wear a mask for long hours.

Methods

In this study, healthcare professionals working at Medipol Mega University Hospital since the beginning of the pandemic were screened for facial dermatoses between December 2020 and February 2021 with a dermatological examination and interview.

Results

Of the 101 healthcare professionals, 51 (50.5%) were doctors and 50 (49.5%) nurses, and 36 (35.6%) were male and 65 (64.4%) were female. All the participants had been actively working at the hospital for 35–46 weeks since the beginning of the pandemic and wearing N95 or surgical masks for an average of 6–13 h a day. During the dermatological examination, the most common facial dermatosis was acne, which was observed in 55.4% (n = 56) of the cases. Of the 56 acne cases, 41.1% (n = 23) had acne in their history, while 58.9% (n = 33) had new‐onset acne. Being female, using a N95 surgical mask compared to surgical mask, and the daily average duration of mask use were determined as risk factors for acne development due to mask use.

Conclusions

The use of masks, more frequently N95, caused both an increase in existing acne and the development of new acne.

Online survey on healthcare skin reactions for wearing medical-grade protective equipment against COVID-19 in Hubei Province, China

With the spread of Coronavirus Disease 2019 globally, more than 40,000 healthcare staff rushed to Wuhan, Hubei Province to fight against this threatening disease. All staff had to wear personal protective equipment (PPE) for several hours when caring for patients, which resulted in adverse skin reactions and injuries. In this study, we used an online questionnaire to collect the self-reported skin damages among the first-line medical staff in the epidemic. The questionnaire was designed by four front-line wound care nurses and then revised through Delphi consultants. Items mainly focused on the adverse skin reactions and preventive strategies. The survey was distributed through phone application from March 15th to March 20th and received 275 responses in total. The prevalence of skin reactions (212, 77.09%) was high in both head and hands. The common clinical symptoms of skin reactions were redness, device-like mark, and burning pain in face; and dryness, dermatitis, and itch/irritation in hands. Three risk factors included gender, level of protection, and daily wearing time of PPE were identified that caused skin reactions among medical staff. 150 of 275 (54.55%) participants took preventive strategies like prophylactic dressings, however, more than 75% users had little knowledge about dressings. We suggest the frontline staff strengthened the protection of skin integrity and reduced the prevalence of adverse skin reactions after professional education.

Dermatological findings in patients admitting to dermatology clinic after using face masks during Covid-19 pandemia: A new health problem

In the present study, the purpose was to evaluate the presence of dermatological symptoms and the effects of mask use on existing dermatological diseases associated with face in patients admitting with any dermatological disease. The present study consisted of 150 patients, including 91 volunteering women and 59 men, admitting to our dermatology clinic with any dermatological symptoms. The presence of symptoms, such as itching, rash, drying and peeling, discomfort, redness, burning, pain, swelling, acne, oily skin symptoms because of mask use, and previous history of facial dermatological disease, whether this disease increased with the use of mask, were questioned. The diagnosis made after dermatological examination and the dermatological examination findings were evaluated with the results of the survey. The most common finding in all patients after mask use was itching with a rate of 64.7%. Similar rates were detected for other symptoms. A significant increase was detected in the severity of acneiform and inflammatory dermatosis after the use of masks (P < .05). Our study showed that long-term mask use caused primary skin symptoms, such as itching, redness, rash, dryness and peeling, burning, oily skin, and acne formation in individuals who have dermatological diseases, and also increased the existing dermatological facial diseases. Therefore, it should be recommended to use water-based moisturizers as it may have a barrier effect on the faces of individuals who use a face mask and have any facial dermatosis, and patients should be closely monitored for skin diseases on the face.

Coronavirus 2 (SARS-CoV-2) in water environments: Current status, challenges and research opportunities

The outbreak of COVID-19 has posed enormous health, social, environmental and economic challenges to the entire human population. Nevertheless, it provides an opportunity for extensive research in various fields to evaluate the fate of the crisis and combat it. The apparent need for imperative research in the biological and medical field is the focus of researchers and scientists worldwide. However, there are some new challenges and research opportunities in the field of water and wastewater treatment concerning the novel coronavirus 2 (SARS-CoV-2). This article briefly summarizes the latest literature reporting the presence of SARS-CoV-2 in water and wastewater/sewage. Furthermore, it highlights the challenges, potential opportunities and research directions in the water and wastewater treatment field. Some of the significant challenges and research opportunities are the development of standard techniques for the detection and quantification of SARS-CoV-2 in the water phase, assessment of favorable environments for its survival and decay in water; and development of effective strategies for elimination of the novel virus from water. Advancement in research in this domain will help to protect the environment, human health, and managing this type of pandemic in the future.

Associations between COVID-19 and skin conditions identified through epidemiology and genomic studies

Background

Coronavirus disease 2019 (COVID-19) is commonly associated with skin manifestations, and may also exacerbate existing skin diseases, yet the relationship between COVID-19 and skin diseases remains unclear.

Objective

By investigating this relationship through a multiomics approach, we sought to ascertain whether patients with skin conditions are more susceptible to COVID-19.

Methods

We conducted an epidemiological study and then compared gene expression across 9 different inflammatory skin conditions and severe acute respiratory syndrome coronavirus 2–infected bronchial epithelial cell lines, and then performed a genome-wide association study transdisease meta-analysis between COVID-19 susceptibility and 2 skin diseases (psoriasis and atopic dermatitis).

Results

Skin conditions, including psoriasis and atopic dermatitis, increase the risk of COVID-19 (odds ratio, 1.55; P = 1.4 × 10⁻⁹) but decrease the risk of mechanical ventilation (odds ratio, 0.22; P = 8.5 × 10⁻⁵). We observed significant overlap in gene expression between the infected normal bronchial epithelial cells and inflammatory skin diseases, such as psoriasis and atopic dermatitis. For genes that are commonly induced in both the severe acute respiratory syndrome coronavirus 2 infection and skin diseases, there are 4 S100 family members located in the epidermal differentiation complex, and we also identified the “IL-17 signaling pathway” (P = 4.9 × 10⁻⁷⁷) as one of the most significantly enriched pathways. Furthermore, a shared genome-wide significant locus in the epidermal differentiation complex was identified between psoriasis and severe acute respiratory syndrome coronavirus 2 infection, with the lead marker being a significant expression quantitative trait locus for S100A12 (P = 3.3 × 10⁻⁷).

Conclusions

Together our findings suggest association between inflammatory skin conditions and higher risk of COVID-19, but with less severe course, and highlight shared components involved in anti–COVID-19 immune response.

Does Wearing a Face Mask During the COVID-19 Pandemic Increase the Incidence of Dermatological Conditions in Health Care Workers? Narrative Literature Review

BACKGROUND

COVID-19 is a health emergency. SARS-CoV-2 was discovered in Wuhan (Hubei Province, China) and has rapidly spread worldwide, leaving no country untouched. COVID-19 is a respiratory infection characterized by a pneumonia of unknown etiology. It is transmitted through respiratory droplets; for example: through breathing, talking, and coughing. Transmission of the virus is high. Health care workers play important roles in helping those affected by COVID-19; this could not be done without the use of personal protective equipment (PPE). PPE involves the use of goggles, masks, gloves, and gowns and is known to reduce COVID-19 transmission; however, multiple reports of skin disease and damage associated with occupational mask-wearing have emerged.

OBJECTIVE

The objective of this study is to review the literature for newly emerging dermatological conditions as a result of occupational mask-wearing during the COVID-19 pandemic.

METHODS

A narrative review of new reports of dermatological conditions associated with occupational mask-wearing was carried out in May 2020 by referencing keywords including: "covid mask dermatology," "covid dermatological damage," "covid mask skin," "covid N95 mask damage," and "covid mask skin damage" from PubMed, supplemented by searches on both Google Scholar and ResearchGate. A total of 287 articles were found, of which 40 were successfully included in this study, and an additional 7 were selected from the reference lists of these 40 articles. The findings were tabulated and analyzed under the following headings: dermatological diagnosis, causes, and management.

RESULTS

Qualitative analysis of the reviewed data was carried out. A number of dermatological conditions were found to increasingly occur owing to prolonged and frequent use of face masks. Pressure-related injuries were often the most serious complaint; recommendations to reduce this type of injury include the use of hydrocolloid dressings, plastic handles, education, and regular moisturization. Innovation in PPE as well as services, such as virtual clinics, need to be advanced to protect the welfare of health care staff.

CONCLUSIONS

In these unprecedented times, PPE has been an effective barrier to the transmission of COVID-19 among health care workers. This has allowed health care workers to provide care to patients, with minimal risk. However, our findings suggest that despite the obvious benefits of using face masks to protect the respiratory system, there are also considerable health consequences to the skin. Future research studies are required to focus on improving face masks to ensure both the protection of the respiratory system as well as skin care, which, according to our study, has been overlooked.

COVID-19 and dermatology

Background/aim

Sars-CoV-2 virus infection (COVID-19) was observed in China in the last months of 2019. In the period following, this infection spread all over the world. In March 2020 the World Health Organization announced the existence of a pandemic. The aim of this manuscript is to investigate skin diseases associated with COVID-19 under three main headings: skin problems related to personal protective equipment and personal hygiene measures, skin findings observed in SARS-CoV-2 virus infections, and skin findings due to COVID-19 treatment agents.

Materials and methods

In PubMed, Google Scholar databases, skin lesions related to personal protective equipment and personal hygiene measures, skin findings observed in SARS-CoV-2 virus infections and skin findings due to COVID-19 treatment agents subjects are searched in detail.

Results

Pressure injury, contact dermatitis, itching, pressure urticaria, exacerbation of preexisting skin diseases, and new skin lesion occurrence/new skin disease occurrence may be due to personal protective equipment. Skin problems related to personal hygiene measures could include itching, dryness, and contact dermatitis. Skin findings may also be observed in SARS-CoV-2 virus infections. The incidence of skin lesions due to COVID-19 was reported to be between 0.2% and 29%. Many skin lesions including maculopapular, urticarial, vesicular, chilblain-like, thrombotic/ischemic, etc. are observed in COVID-19 patients. Some authors have stated that there is an absence of SARS-CoV-2 virus infection-specific skin findings. However, in asymptomatic or presymptomatic COVID-19 patients in particular, skin lesions can lead to the diagnosis of COVID-19. In addition, skin lesions may occur due to COVID-19 treatment agents.

Conclusion

Many skin lesions may appear as a result of COVID-19. Even in the absence of a COVID-19 diagnosis, skin findings should be evaluated carefully in this pandemic period.

Biosafety Measures at the Dental Office After the Appearance of COVID-19: A Systematic Review

The purpose of this research was to determine biosecurity measures at the dental office after the appearance of coronavirus disease 2019 (COVID-19). A search was conducted in the main databases of the scientific literature using the words “COVID-19, coronavirus, SARS-Cov2, biosecurity, disinfection and dentistry.” We analyzed biosecurity and disinfection standards at the dental office and dental health personnel to date, and their adaptation to the needs and way of working of each. As a result, according to the information collected the following procedure was identified: a telephone appointment must be made and a questionnaire should be given before dental care; at arrival to the appointment, the temperature of the patient should be taken and proper cleaning and disinfection of the waiting room should be maintained. Panoramic radiography and CBCT are the auxiliary methods of choice. Absolute isolation and atraumatic restorative therapy techniques are a good alternative to decrease fluid exposure. The removal of protective clothing and accessories must follow a specific order and washing hands before and after is essential. In conclusion, the efficient biosecurity for dentists and patients in all dental care processes before, during, and immediately after the appointment reduces the risk of COVID-19 infection and allows healthy dental care environments.

Cutaneous manifestations and considerations in COVID-19 pandemic: A systematic review

COVID-19 had a great impact on medical approaches among dermatologist. This systematic review focuses on all skin problems related to COVID-19, including primary and secondary COVID-related cutaneous presentations and the experts recommendations about dermatological managements especially immunomodulators usage issues. Search was performed on PubMed, Scopus, Embase and ScienceDirect. Other additional resources were searched included Cochrane, WHO, Medscape and coronavirus dermatology resource of Nottingham university. The search completed on May 3, 2020. Three hundred seventy-seven articles assigned to the inclusion and exclusion groups. Eighty-nine articles entered the review. Primary mucocutaneous and appendageal presentations could be the initial or evolving signs of COVID-19. It could be manifest most commonly as a maculopapular exanthamatous or morbiliform eruption, generalized urticaria or pseudo chilblains recognized as "COVID toes" (pernio-like acral lesions or vasculopathic rashes). During pandemic, Non-infected non-at risk patients with immune-medicated dermatologic disorders under treatment with immunosuppressive immunomodulators do not need to alter their regimen or discontinue their therapies. At-risk o suspected patients may need dose reduction, interval increase or temporary drug discontinuation (at least 2 weeks). Patients with an active COVID-19 infection should hold the biologic or non-biologic immunosuppressives until the complete recovery occur (at least 4 weeks).
