Cutaneous Manifestations in Adult Patients with COVID-19 and Dermatologic Conditions Related to the COVID-19 Pandemic in Health Care Workers

Neutrophil heterogeneity and aging: implications for COVID-19 and wound healing

Neutrophils play a critical role in the immune response to infection and tissue injury. However, recent studies have shown that neutrophils are a heterogeneous population with distinct subtypes that differ in their functional properties. Moreover, aging can alter neutrophil function and exacerbate immune dysregulation. In this review, we discuss the concept of neutrophil heterogeneity and how it may be affected by aging. We then examine the implications of neutrophil heterogeneity and aging for COVID-19 pathogenesis and wound healing. Specifically, we summarize the evidence for neutrophil involvement in COVID-19 and the potential mechanisms underlying neutrophil recruitment and activation in this disease. We also review the literature on the role of neutrophils in the wound healing process and how aging and neutrophil heterogeneity may impact wound healing outcomes. Finally, we discuss the potential for neutrophil-targeted therapies to improve clinical outcomes in COVID-19 and wound healing.

Defining the short-term and long-term skin manifestations of COVID-19: insights after more than three years of the pandemic

AIM

This review aimed to assess the impact of coronavirus disease 2019 (COVID-19) on skin health to establish a classification of the skin lesions that occur most frequently during the disease and whether a particular category of skin damage is more likely to occur both in the short term and in the long term.

METHODS

We conducted a literature search of the PubMed database. Ultimately, 109 articles were included in this review. The exact phrases∕syntax and connectors used for the database search∕query were as follows: "Coronavirus and skin", "COVID-19 and skin", "SARS-CoV-2 and skin", "Coronavirus cutaneous manifestations", "COVID-19 cutaneous manifestations", "SARS-CoV-2 cutaneous manifestations", "Coronavirus dermatology", "SARS-CoV-2 and dermatology", "COVID-19 and dermatology", "COVID-19 and skin eruption", "Coronavirus and skin rash", "COVID-19 and hair", "Coronavirus and hair", "Coronavirus and nails", "SARS-CoV-2 and hair", and "SARS-CoV-2 and nails". Only articles with abstracts referring strictly to cutaneous manifestations of COVID-19 were chosen. Articles without abstracts were not considered.

RESULTS

We established six of the most frequently reported clinical patterns associated with COVID-19 and their probability of occurring during COVID-19 disease evolution based on the current literature reports. We did not identify the particular types of skin lesions that are most prone to long-term persistence; most such cases are rare, and no conclusion can be drawn based on them.

CONCLUSIONS

Apart from classified COVID-19-related skin disorders, this pandemic has been a challenge for dermatologists and a wide range of cutaneous side effects related to severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) treatments have been reported. We are aware of other polymorphic clinical presentations, with novel data being reported periodically, but the pathophysiological mechanisms and evolution are largely unknown.

A case of acute generalized exanthematous pustulosis following COVID-19 infection and remdesivir

We report a challenging AGEP case following COVID-19 infection and a history of remdesivir use. Our study highlights the importance of considering history of COVID-19 and remdesivir as possible causative factors when visiting new-onset AGEP patients.

The Effect of Covid-19 on the Hair Diseases Observed in Health Care Providers: Analysis of 513 Participants

INTRODUCTION

The Covid-19 pandemic has been shown to have major acute and chronic impacts on the skin. Various studies reported that there has been an increase in the number of patients referred to outpatient dermatology clinics with the complaint of variable hair diseases during the era of Covid-19. Hair seems to be substantially affected by both the infection itself and anxiety/stress provoked by the pandemic. Therefore, understanding the impact of Covid-19 on the clinical course of variable hair diseases has become a major concern in dermatology practice.

OBJECTIVES

To examine the frequency and types of various hair diseases, both new-onset and ingravescent, observed in healthcare providers.

METHODS

A web-based questionnaire related to the hair diseases seen in healthcare providers both prior to the Covid-19 pandemic and after the start of the pandemic was created. The type of both new-onset and pre-existing hair diseases and ongoing hair diseases observed during Covid-19 were investigated.

RESULTS

A total number of 513 participants were included in the study. One hundred seventy cases were diagnosed with Covid-19. During the Covid-19 pandemic, 228 reported having at least one hair disease; the most common one being telogen effluvium, followed by hair greying and seborrheic dermatitis. There was a statistically significant relationship between the presence of a new-onset hair disease during the pandemic and being diagnosed with Covid-19 (p=0.004).

CONCLUSION

Our study shows that Covid-19 infection has a significant impact on the emergence of new-onset hair diseases.

Pressure Injury Management in Critically Ill Patients with COVID-19 in a Makeshift Hospital in Indonesia: A Report of Two Cases

ABSTRACT

Patients who are critically ill with COVID-19 need ventilation support in the ICU. However, ICU patients are at higher risk of developing a pressure injury (PI). Unfortunately, PI prevention is not optimally implemented in Indonesia, especially in the makeshift hospitals created during the COVID-19 pandemic. Here, the authors report two cases of critically ill patients with COVID-19 who developed large sacral PIs during hospitalization in a makeshift hospital in Indonesia. The first patient developed a stage 3, 7 × 7-cm sacral PI on the 14th day of hospitalization. The second patient developed a stage 4, 12 × 8-cm sacral PI on the 16th day of hospitalization. Both patients had elevated d-dimer levels and used a noninvasive ventilator for 1 week. The wounds were treated with surgical debridement, silver hydrogel dressing, and hydrocolloid dressing and complemented with static air mattress overlay. The authors recommend that in situations where there is a shortage of healthcare workers, the government should provide pressure-redistribution devices and silicone foam dressings for all critically ill patients to prevent PI development and lighten the workload of healthcare workers.

Cutaneous Eruptions in the Course of COVID-19 Among Geriatric Patients in a Nursing Home in Poland

Purpose

The aim of this study was to assess the incidence and characteristics of COVID-19 cutaneous manifestations among geriatric patients infected with the SARS-CoV-2 virus.

Patients and Methods

Sixty-four nursing home residents in Dobre Miasto, Poland (mean age: 79 years) infected with SARS-CoV-2 were monitored for skin lesions during the epidemic outbreak in 2020. Only five of them presented COVID-19 dermatological manifestation: vesicular (4 cases) and erythematous (1 case) skin lesions, which appeared after the remaining symptoms of the disease had resolved.

Results

The average time between COVID-19 onset and cutaneous manifestation was 22 days. Skin lesions persisted in five cases 112, 17, 21,19 and 27 days, respectively, and were often accompanied by pruritus and neuropathic pain.

Conclusion

Skin manifestations of SARS-CoV-2 infection might be misdiagnosed or overlooked, particularly among elderly patients with chronic diseases. The recognition of skin lesions due to COVID-19 might improve patients' quality of life by reducing the intensity of symptoms such as pruritus or neuropathic pain.

Immunological aspects of COVID-19 related skin manifestations: revisiting pathogenic mechanism in the light of new evidence

The newly emerged coronavirus disease 2019 (COVID‐19), induced by a novel strain of the coronavirus family, named severe acute respiratory syndrome coronavirus 2 (SARS‐CoV‐2), is a rapidly spreading global threat. This virus affects a fair number of tissues in the human body by availing itself of potential target receptors like Angiotensin‐Converting Enzyme 2 (ACE2). Presenting with diverse clinical manifestations, COVID‐19 has raised the urge for extensive research in different medical fields, including dermatology. Developing a comprehensive knowledge of cutaneous manifestations is highly important as it can help us in early diagnosis and better management of the ongoing pandemic. The dermatological presentations of COVID‐19 are classified into main categories of vascular and non‐vascular (exanthematous) patterns. Though not yet fully confirmed, the pathogenesis of these cutaneous presentations has been suggested to be more related to the overactivation of the immune system. In this review, we discuss in detail the clinical features of the diverse skin lesions in COVID‐19 patients and the imperative role of the immune system in their pathogenesis and development. Furthermore, we will discuss the reasons behind the accentuation of skin lesions in COVID‐19 compared to the same virus family predecessors.

Erythema multiforme as a presentation of COVID-19: Case Illustrated format

COVID-19 is now an established morbidity across races, regions and clinical risks around the world. From its first detection in Wuhan city-China in 2019 to the recent breakthrough of approved vaccines, that are determinants and deterrents and gradually becoming apparent. The phenotype of its presentation however is both variable and challenging especially. For those presenting with unique skin dermatosis such as erythema multiforme. Case report Our case is on a 36 year- old gentleman who presented to the hospital complaining, initially of only urticarial rash (later established to be erythema multiform), which improved with symptomatic treatment. He was discharged, only to be re-admitted a week later with exacerbation of the former cutaneous manifestation, accompanied by fever and gastrointestinal symptoms. He ultimately made complete recovery and was discharged home.

The Well-Being of Healthcare Workers During the COVID-19 Pandemic: A Narrative Review

The coronavirus disease 2019 (COVID-19) pandemic has turned into a global healthcare challenge, causing significant morbidity and mortality.Healthcare workers (HCWs) who are on the frontline of the COVID-19 outbreak response face an increased risk of contracting the disease. Some common challenges encountered by HCWs include exposure to the pathogen, psychological distress, and long working hours. In addition, HCWs may be more prone to develop mental health issues such as anxiety, depression, suicidal thoughts, post-traumatic stress disorder (PTSD), sleep disorders, and drug addictions compared to the general population. These issues arise from increased job stress, fear of spreading the disease to loved ones, and potential discrimination or stigma associated with the disease. This study aims to review the current literature to explore the effects of COVID-19 on healthcare providers' physical and mental well-being and suggest interventional strategies to combat these issues. To that end, we performed a literature search on Google Scholar and PubMed databases using combinations of the following keywords and synonyms: "SARS-CoV-2", "Healthcare-worker", "COVID-19", "Well-being", "Wellness", "Depression", "Anxiety", and "PTSD."

Adverse skin reactions to personal protective equipment ( PPE ) during COVID ‐19 pandemic in Italian health care workers

To avoid exposure to SARS‐COV‐2, healthcare professionals must use personal protective equipment (PPE). Their use has been related to a series of adverse effects; the most frequent adverse events were headache, dyspnoea, and pressure injuries. Skin adverse effects are very common, including contact dermatitis, itching, erythema, and acneiform eruptions. The objective of this study is to evaluate the skin problems caused by personal protection equipment (PPE) in health care workers (HCWs) and to individuate eventual risk factors. From May to June 2020 a retrospective observational multi‐centric study conducted by an online survey sent by email, involving 10 hospital centers, was performed. We considered as independent variables gender and age, occupational group and sector, time of utilization, type and material of PPE. We tested 3 types of PPE: gloves, bonnet, and mask for different time of utilization (<1, 1–3, 3–6, >6 h). We performed a multiple logistic regression model to correlate them with skin adverse events occurrence. Among all the 1184 participants, 292 workers reported a dermatological pathology: 45 (15.41%) had psoriasis, 54 (18.49%) eczema, 38 (13.01%) acne, 48 (16.44%) seborrheic dermatitis, and 107 (36.64%) other. In our sample previous inflammatory dermatological conditions, female sex, prolonged use of PPE were significant risk factors for developing skin related adverse events considering all the PPE considered. The use of PPE is still mandatory in the hospital setting and skin adverse reactions still represent a global problem. Although data from Europe are limited, our study highlighted the importance of the problem of PPE skin reactions in a large sample of Italian healthcare professionals.

COVID-19 Skin Manifestations in Skin of Colour

Coronavirus disease (COVID-19) skin manifestations have been increasingly reported in medical literature. Recent discussions have identified a lack of images of skin of color (SOC) patients with COVID-19 related skin findings despite people with skin of color being disproportionately affected with the disease. There have been calls to prioritize the identification of COVID-19 skin manifestations in patients with SOC and disseminate these findings. The objective of this article is to review the existing literature on COVID-19 skin manifestations and, where possible, discuss how they may present differently in patients with SOC. Further research is needed to allow primary care physicians and dermatologists to be aware of and easily identify patients with cutaneous findings that may be secondary to COVID-19. Patients presenting with idiopathic dermatologic manifestations should be considered for COVID-19 testing and follow public health guidelines for self-isolation.

Impact in Contact Dermatitis during and after SARS-CoV2 Pandemic

Purpose of the review

Due to the recent COVID-19 pandemic, several skin conditions have emerged due to the preventive measures adopted by both health care workers and the general population against SARS-CoV-2. Above all, wearing of personal protective equipment, frequent hand-washing and disinfecting of surfaces have resulted in an increased risk of irritant or allergic contact dermatitis. The aim of this review is to investigate contact dermatitis associated with COVID-19 pandemic period.

Recent findings

There is a real evidence of the rising prevalence of irritant and allergic contact dermatitis in response to the COVID-19 pandemic. The most commonly recorded symptoms are dryness, itch and redness of the skin. Nasal bridge, cheeks, forehead and hands represent the mainly affected skin sites.

Summary

Contact dermatitis lesions may appear as a result of various recommendations to prevent transmission of COVID-19. Procedures to alleviate pressure and friction, gentle skin care and adequate moisturizing, have been identified as important preventive strategies for contact dermatitis related to personal protective equipment and personal hygiene measures.

Extra-Pulmonary Complications in SARS-CoV-2 Infection: A Comprehensive Multi Organ-System Review

Coronavirus disease (COVID-19), caused by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection, is typically presented with acute symptoms affecting upper and lower respiratory systems. As the current pandemic progresses, COVID-19 patients are experiencing a series of nonspecific or atypical extra-pulmonary complications such as systemic inflammation, hypercoagulability state, and dysregulation of the renin-angiotensin-aldosterone system (RAAS). These manifestations often delay testing, diagnosis, and the urge to seek effective treatment. Although the pathophysiology of these complications is not clearly understood, the incidence of COVID-19 increases with age and the presence of pre-existing conditions. This review article outlines the pathophysiology and clinical impact of SARS-CoV-2 infection on extra-pulmonary systems. Understanding the broad spectrum of atypical extra-pulmonary manifestations of COVID-19 should increase disease surveillance, restrict transmission, and most importantly prevent multiple organ-system complications.

Demographic Characteristics of the Patients with Cutaneous Vasculitis Due to COVID-19 Infection

Background

Cutaneous manifestations of coronavirus disease 2019 (COVID-19) range from mild skin rashes to severe vasculitis. In the current study, we evaluated the demographic characteristics of the patients with cutaneous vasculitis following COVID-19 infection.

Materials and Methods

In the current study, we evaluated 799 hospitalised patients with COVID-19 infection for development of cutaneous vasculitis. Demographic and clinical characteristics of the patients were obtained using questionnaires and patients' records. Cutaneous vasculitis of the suspected patients were confirmed using skin biopsy and direct immunofluorescence.

Results

We detected 24 hospitalised cases with cutaneous vasculitis presenting with petechia, purpura, livedoretcularis and acrocyanosis. Our data showed a significant relationship between male sex, advanced age, C-reactive protein (CRP) level and presence of comorbidities with development of cutaneous vasculitis. In addition, we found a positive association between the severity of COVID-19 infection and occurrence of cutaneous vasculitis.

Conclusion

Our findings are suggestive that clinicians must be aware of cutaneous vasculitis risk as prognostic value in the patients with severe COVID-19 infection.

The course of acne in healthcare workers during the COVID-19 pandemic and evaluation of possible risk factors

BACKGROUND

There are a limited number of publications reporting an increase in acne in the COVID-19 outbreak.

OBJECTIVE

The study aimed to evaluate the course and the clinical features of acne and possible risk factors during the COVID-19 pandemic in healthcare workers.

METHOD

A total of 172 physicians (female, n = 159, male; n = 13, mean age = 35.03 ± 5.27 years) who had acne in any period of their life were included in the study. A self-administered online questionnaire was applied.

RESULTS

During the COVID-19 pandemic, 45.35% of the participants reported that their acne complaints increased, 27.33% reported relapses, and 7.56% reported occurrence for the first time. Newly formed acne was reported most frequently on the chin (78.26%). The number of female participants, smoking, increased stress, and the rate of surgical mask use were found to be higher in the group whose acne occurred for the first time, relapsed, or increased than in the group whose acne complaints were unchanged or decreased (p < 0.05). In the group whose acne relapsed or increased, adult-onset acne, presence of scar, and use of systemic acne treatment before the COVID-19 pandemic were more common than in the group whose acne complaints were unchanged or decreased (p < 0.05).

CONCLUSION

Almost half of the participants reported an increase in acne. More than a third of the participants reported that their acne relapsed or they had acne for the first time. In addition to the use of surgical masks, factors such as increased stress, smoking, adult-onset acne, presence of scar, and previous systemic acne treatment were found to be responsible for acne development.

The Third Wave of the COVID-19 Arrived in Afghanistan: A Severe Case with Skin Manifestation

The COVID-19 is an ongoing global pandemic that has put the world in a devastating situation. The virus is able to attack multiple body systems and cause a variety of clinical problems ranging from asymptomatic to critical cases. Although young individuals are more likely to suffer milder forms of the disease, critical cases also might happen. Recent literature has revealed that, along with other clinical symptoms, skin manifestations have also progressively grown. In Afghanistan where COVID-19 has entered into a third wave, many people do not take the initial mild symptoms seriously to prevent further spreading in the community. We report symptoms of skin rash, fatigue, muscle pain, dry cough and fever at the onset of the disease, followed by rapid lung damage in a 23-year-old young adult, who did not have any preexisting risk factors. This case highlights the importance of urgent skin assessment of the COVID-19 patient complaining of any skin symptoms.

Microvascular Skin Manifestations Caused by COVID-19

Hypercoagulability and vascular injury, which characterize morbidity in COVID-19 disease, are frequently observed in the skin. Several pathomechanisms, such as inflammation caused by angiotensin-converting enzyme 2-mediated uptake into endothelial cells or SARS-CoV-2-initiated host immune responses, contribute to microthrombus formation and the appearance of vascular skin lesions. Besides pathophysiologic mechanisms observed in the skin, this review describes the clinical appearance of cutaneous vascular lesions and their association with COVID-19 disease, including acro-ischemia, reticular lesions, and cutaneous small vessel vasculitis. Clinicians need to be aware that skin manifestations may be the only symptom in SARS-CoV-2 infection, and that inflammatory and thrombotic SARS-CoV-2-driven processes observed in multiple organs and tissues appear identically in the skin as well.

Presence and clinical impact of human herpesvirus-6 infection in patients with moderate to critical coronavirus disease-19

Human herpesvirus-6 (HHV-6) may cause serious diseases in immunocompromised individuals. SARS-CoV-2/HHV-6 coinfection has been emphasized in previous works, mostly case reports, small series, or epidemiological studies, but few are known about its real clinical outcomes. Here we present a real-world pilot study aiming to understand the frequency and the clinical impact of HHV-6 coinfection in moderate to critically ill patients hospitalized due to COVID-19. SARS-CoV-2 and HHV-6 were evaluated in nasopharyngeal samples at the hospital admission of suspected COVID-19 patients. From 173 consecutive cases, 60 were SARS-CoV-2 positive and 13/60 (21.7%) were HHV-6 positive after identified as the HHV-6B species by a Sanger sequencing. The SARS-CoV-2+/HHV-6+ group was younger but not significant for cardiovascular diseases, diabetes, obesity, and cancer, but significant among therapeutic immunosuppressed patients (as systemic lupus erythematosus and kidney transplant patients). In the medical records, only sparse data on cutaneous or neurological manifestations were found. Biochemical and hematological data showed only a trend towards hyperferritinemic status and lymphopenia. In conclusion, despite the impressive high frequency of HHV-6 coinfection in SARS-CoV-2 positive cases, it did not impact general mortality. We suggest larger future prospective studies to better elucidate the influence of HHV-6 reactivation in cases of COVID-19, designed to specific assessment of clinical outcomes and viral reactivation mechanisms.

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.

Identification, Mechanism, and Treatment of Skin Lesions in COVID-19: A Review

Coronavirus disease 2019 (COVID-19) is a multisystem disease caused by Severe Acute Respiratory Syndrome Coronavirus 2 (SARS-CoV-2), that primarily causes respiratory symptoms. However, an increasing number of cutaneous manifestations associated with this disease have been reported. The aim of this study is to analyze the scientific literature on cutaneous manifestations associated with SARS-CoV-2 by means of a narrative literature review until June 2021. The search was conducted in the following electronic databases: Medline (PubMed), SciELO, and Cochrane Library Plus. The most common cutaneous manifestations in patients with COVID-19 are vesicular eruptions, petechial/purpuric rashes, acral lesions, liveoid lesions, urticarial rash, and maculopapular-erythematous rash. These manifestations may be the first presenting symptoms of SARS-CoV-2 infection, as is the case with acral lesions, vesicular eruptions, and urticaria. In relation to severity, the presence of liveoid lesions may be associated with a more severe course of the disease. Treatment used for dermatological lesions includes therapy with anticoagulants, corticosteroids, and antihistamines. Knowledge of the dermatologic manifestations associated with SARS-CoV-2 contributes to the diagnosis of COVID-19 in patients with skin lesions associated with respiratory symptoms or in asymptomatic patients. In addition, understanding the dermatologic lesions associated with COVID-19 could be useful to establish a personalized care plan.

Review of COVID-19, part 2: Musculoskeletal and neuroimaging manifestations including vascular involvement of the aorta and extremities

The coronavirus disease 2019 (COVID-19) pandemic caused by the novel severe acute respiratory syndrome coronavirus (SARS-CoV-2) has affected almost every country in the world resulting in severe morbidity, mortality and economic hardship, altering the landscape of healthcare forever. Its devastating and most frequent thoracic and cardiac manifestations have been well reported since the start of the pandemic. Its extra-thoracic manifestations are myriad and understanding them is critical in diagnosis and disease management. The role of radiology is growing in the second wave and second year of the pandemic as the multiorgan manifestations of COVID-19 continue to unfold. Musculoskeletal, neurologic and vascular disease processes account for a significant number of COVID-19 complications and understanding their frequency, clinical sequelae and imaging manifestations is vital in guiding management and improving overall survival. The authors aim to provide a comprehensive overview of the pathophysiology of the virus along with a detailed and systematic imaging review of the extra-thoracic manifestation of COVID-19. In Part I, abdominal manifestations of COVID-19 in adults and multisystem inflammatory syndrome in children will be reviewed. In Part II, manifestations of COVID-19 in the musculoskeletal, central nervous and vascular systems will be reviewed.

Insights into Innate Immune Response Against SARS-CoV-2 Infection

The innate immune system is mandatory for the activation of antiviral host defense and eradication of the infection. In this regard, dendritic cells, natural killer cells, macrophages, neutrophils representing the cellular component, and cytokines, interferons, complement or Toll-Like Receptors, representing the mediators of unspecific response act together for both activation of the adaptive immune response and viral clearance. Of great importance is the proper functioning of the innate immune response from the very beginning. For instance, in the early stages of viral infection, the defective interferon response leads to uncontrolled viral replication and pathogen evasion, while hypersecretion during the later stages of infection generates hyperinflammation. This cascade activation of systemic inflammation culminates with cytokine storm syndrome and hypercoagulability state, due to a close interconnection between them. Thus an unbalanced reaction, either under- or over- stimulation of the innate immune system will lead to an uncoordinated response and unfavorable disease outcomes. Since both cellular and humoral factors are involved in the time-course of the innate immune response, in this review we aimed to address their gradual involvement in the antiviral response with emphasis on key steps in SARS-CoV-2 infection.

Pericardial Diseases in COVID19: a Contemporary Review

PURPOSE OF REVIEW

Coronavirus disease 2019 (COVID19) involves the heart, including pericardium. This article reviews the possible pathophysiological mechanisms in pericardial involvement in COVID19 and pericardial manifestations of COVID19. It also summarizes the patients with pericarditis secondary to COVID19 and outlines the contemporary treatment strategies in this patient population.

RECENT FINDINGS

A high degree of suspicion is required to identify the pericardial involvement in COVID19 patients. It is proposed that an underlying hyperinflammatory reaction in COVID19 leads to pericardial inflammation. Acute pericarditis with or without myocardial involvement is diagnosed on clinical presentation, serum inflammatory markers, electrocardiogram, and echocardiogram. Multimodality imaging may also have an additional diagnostic value. Patients are usually managed medically, but some patients develop a life-threatening pericardial tamponade necessitating pericardial drainage. Pericardial involvement is an important clinical manifestation of COVID19 requiring a proper workup. Timely diagnosis and a specific management plan based on the presentation and concomitant organ involvement usually lead to a complete recovery.

SARS-CoV-2 infection as a potential triggering factor for urticarial vasculitis during pregnancy: A case report

During the COVID-19 pandemic, physicians must maintain a high index of suspicion for COVID-19 in cases of urticarial vasculitis or other forms of urticaria. This is particularly important for acute presentations in otherwise asymptomatic individuals and pregnant women, where a prompt approach to the patient can prevent undesirable complications.

Opportunities, Challenges and Pitfalls of Using Cannabidiol as an Adjuvant Drug in COVID-19

Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection may lead to coronavirus disease 2019 (COVID-19) which, in turn, may be associated with multiple organ dysfunction. In this review, we present advantages and disadvantages of cannabidiol (CBD), a non-intoxicating phytocannabinoid from the cannabis plant, as a potential agent for the treatment of COVID-19. CBD has been shown to downregulate proteins responsible for viral entry and to inhibit SARS-CoV-2 replication. Preclinical studies have demonstrated its effectiveness against diseases of the respiratory system as well as its cardioprotective, nephroprotective, hepatoprotective, neuroprotective and anti-convulsant properties, that is, effects that may be beneficial for COVID-19. Only the latter two properties have been demonstrated in clinical studies, which also revealed anxiolytic and antinociceptive effects of CBD (given alone or together with Δ9-tetrahydrocannabinol), which may be important for an adjuvant treatment to improve the quality of life in patients with COVID-19 and to limit post-traumatic stress symptoms. However, one should be aware of side effects of CBD (which are rarely serious), drug interactions (also extending to drugs acting against COVID-19) and the proper route of its administration (vaping may be dangerous). Clearly, further clinical studies are necessary to prove the suitability of CBD for the treatment of COVID-19.

Dermatological manifestations during COVID-19 infection: a case series and discussion on the problem of differential diagnosis

On March 11, 2019 the World Health Organization (WHO) declared Coronavirus disease-2019 (COVID-19), caused by SARS-CoV-2, as a pandemic. As of 15/01/2021, more than ninety million cases of infections have been confirmed, with almost two million related deaths. SARS-CoV-2 causes bilateral interstitial pneumonia, which can responsible of respiratory failure in the most severe cases, but the virus has also a wide range of other manifestations, including gastrointestinal, cardiovascular, neurological, and cutaneous signs and symptoms. Cutaneous manifestations are an important matter of study for allergy specialists, as they can be specific signs of the infection, but also manifestations of adverse reactions to the medical therapy in use. In this case series, we report four different cases of dermatological manifestations in COVID patients, two in hospitalised patients and two in patients with mild disease, treated at home. The first case reported is a woman, who develops urticaria while being treated at home with mild COVID-infection; the second and the third one case reported are drug- hypersensivity reaction to remdesevir and low molecular weight heparin. The last case reported is a man with mild covid with vasculitic sacral lesions. Key words: COVID pandemic, SARS-CoV-2, dermatological manifestation in covid infections, remdesevir hypersensitivity, covid and urticaria, covid and vasculitic lesions.

Facial masks vestibulitis: the risk of mismanagement in the COVID-19 pandemic

The COVID-19 pandemic has forced the global population to adopt several public health measures, including social distancing, environmental disinfection and use of personal protective equipment (PPE), which are still widely recommended although several vaccines are currently available. Dermatological and allergological diseases related to the extended use of the PPEs represent an emerging problem amidst the pandemic. In particular, there are increasing reports of skin damage, occupational dermatoses, Irritant Contact Dermatitis (ICD) and allergic contact dermatitis (ACD) related to surgical facemasks and N95. We report the case of a superinfected ICD of the narinal region complicated in nasal vestibulitis, characterized by purulent secretions, narinal edema and nasal obstruction, with the aim of highlighting that even the incorrect use of protective against Covid-19 transmission can cause the onset of severe diseases.
