    Background: The COVID-19 pandemic has dramatically changed medical practice worldwide. It posed a significant impact on different health services, including dermatology. Methods and objectives: Two online surveys were conducted to determine the prevalence SERO of personal protective equipment-related skin complications (200 healthcare providers were included) and to demonstrate the outbreak s impact on dermatology practice (100 dermatologists were included). Results: In the first survey, the response rate was 72.46%. PPE- related dermatoses were reported by 147 (73%) participants, including frictional dermatitis MESHD (51.9%), mechanical acne HP (33.1%), contact dermatitis HP dermatitis MESHD (29.9%), nonspecific rash MESHD (17.5%), urticaria HP urticaria MESHD (9.1%) and skin infections MESHD (3.2%). The response rate of the second survey was 64%. COVID-19 emerging cutaneous manifestations were recognized by 20% of dermatologists, including maculopapular rash MESHD (41.67%), urticaria HP urticaria MESHD (37.50%), chilblain HP (25%) and vasculitis HP vasculitis MESHD (16.67). Telemedicine was provided by 73% of the dermatologists. The relapse rates of psoriasis MESHD, atopic dermatitis HP atopic dermatitis MESHD, rosacea, vitiligo HP vitiligo MESHD and alopecia areata HP were noticeably increased as observed by 62%, 50%, 20%, and 4% of dermatologists, respectively. Most dermatologists (89%) reported minimal use of immunosuppressive drugs amid the pandemic. Conclusions: This article highlights the pivotal role of dermatologists in the leading edge during the current health crisis and how they adapt to these unfamiliar circumstances to meet the challenges. It documents the emergence of PPE-related dermatoses among healthcare providers and the impact of COVID-19 on different aspects of dermatology practice.

    COVID-19: Neutrophils “Unfriendly Fire” Imbalance Proteolytic Cascades Triggering Clinical Worsening and Viral Sepsis MESHD Sepsis HP. Potential Role Explanation for Convalescent Plasma SERO as “Fire Hose”

    Based on Chinese CDCP report on COVID-19, 14% of patients presented severe disease and 5% critical conditions. The average case-fatality rate was 2.3%, but mortality was as high as 49% in patients with critical illness MESHD. Serious life threatening thromboembolic MESHD complications have been found in 71·4% of non-survivors and micro/macro angiopathic coagulopathy MESHD has been found, also at autopsy, with highly increased neutrophil number, fibrinogen, concentrations of D-dimer and FDPs and NETs, ATIII decrease and normal number of platelets. A cytokine storm and interaction between inflammation MESHD and coagulation has been advocated as explanation of hypercoagulability HP hypercoagulability MESHD. In this paper, it’s hypothesised that SARS-CoV-2 infection MESHD of alveolar MESHD cells induces recruitment of innate responder neutrophils, which release proteases and NETs inducing endothelial damage/endotheliopathy and imbalance of the four major proteolytic cascades (coagulation, complement, fibrinolysis and kallikrein) with prevalence SERO of activators over inhibitors and consequent thrombotic complications MESHD. Platelets adhesion to damaged endothelium and the presence of ULVWF multimers, due to decreased ADAMTS13, contributes to the state of hypercoagulability HP hypercoagulability MESHD. Neutrophil innate “unfriendly fire” response can be identified as the trigger of a “proteolytic storm”, responsible for subsequent well known prothrombotic condition and “cytokine storm”. The hypothesis explains also the pathology of recently described systemic “ Kawasaki Disease MESHD like” vasculitis HP vasculitis MESHD cases in Covid-19 young ill patients.
