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).

Review
In patients with specific dermatologic disorders who are affected by new corona virus, we know little about disease course (underlying disease and new onset infection), and the most proper management strategies include both issues that are what this systematic review targets. Databases of PubMed, Scopus, Google Scholar, Medscape, and Centre of Evidence-Based Dermatology, coronavirus dermatology resource of Nottingham University searched completely up to May 15, 2020, and initial 237 articles were selected to further review and finally 9 articles (including 12 patients) entered to this study. From 12 patients with chronic underlying dermatologic disease treated with systemic therapies, only 1 patient required Intensive Care Unit admission, the others have been treated for mild-moderate symptoms with conventional therapies. The biologic or immunosuppressive/immunomodulator agents have been ceased during the course of disease. The course of coronovirus diseases 2019 (COVID-19) and its management was as similar as normal populations. Their underlying dermatologic disease were exacerbating from mild to moderate. Their treatment has been continued as before, after the symptoms improved. Exacerbation of patients underlying dermatologic disease was mild to moderate. Discontinuing the treatment in the acute period of COVID and the restart after recovery may prevent severe recurrence and disturbing cytokine storms in these patients.

Review
BACKGROUND
Autoimmune blistering diseases (AIBD) are characterised by the body's production of autoantibodies against structural proteins in the epidermis and/or the basement membrane on cutaneous and mucosal surfaces. Alopecia is a complication of AIBD that has generally been overlooked in patients with severe blistering diseases because it is regarded as a cosmetic issue. Yet recent research into quality of life tools has found that stigmatisation by appearance plays a significant role in blistering diseases.
AIM
To review the current literature detailing the pathogenesis and clinical presentations of alopecia in AIBD patients.
METHOD
We searched Medline, PubMed and EMBASE electronic databases up to September 2018, for empirical human and animal studies.
RESULTS
Only 36 human studies including 223 patients (190 pemphigus, 25 pemphigoid, 5 epidermolysis bullosa acquisita, 2 dermatitis herpetiformis and 1 linear IgA disease) detailed demographic and clinical manifestations of alopecia. A range of hair evaluation methods was demonstrated to reach alopecia diagnosis. Furthermore, with no universal validated scoring system for alopecia severity, alopecia patterns have been summarised.
CONCLUSION
Previous randomised trials have not highlighted alopecia as an important outcome of AIBD, so epidemiological evaluation of the available literature has been helpful in summarising trends between existing studies and demonstrating inconsistencies.

During the past years biologic agents (also termed biologicals or biologics) have become a crucial treatment option in immunological diseases. Numerous articles have been published on biologicals, which complicates the decision making process on the use of the most appropriate biologic for a given immune-mediated disease. This systematic review is the first of a series of articles assessing the safety and efficacy of B cell-targeting biologics for the treatment of immune-mediated diseases. To evaluate rituximab's safety and efficacy for the treatment of immune-mediated disorders compared to placebo, conventional treatment, or other biologics. The PRISMA checklist guided the reporting of the data. We searched the PubMed database between 4 October 2016 and 26 July 2018 concentrating on immune-mediated disorders. The literature search identified 19,665 articles. After screening titles and abstracts against the inclusion and exclusion criteria and assessing full texts, 105 articles were finally included in a narrative synthesis. Rituximab is both safe and effective for the treatment of acquired angioedema with C1-inhibitor deficiency, ANCA-associated vasculitis, autoimmune hemolytic anemia, Behçet's disease, bullous pemphigoid, Castleman's disease, cryoglobulinemia, Goodpasture's disease, IgG4-related disease, immune thrombocytopenia, juvenile idiopathic arthritis, relapsing-remitting multiple sclerosis, myasthenia gravis, nephrotic syndrome, neuromyelitis optica, pemphigus, rheumatoid arthritis, spondyloarthropathy, and systemic sclerosis. Conversely, rituximab failed to show an effect for antiphospholipid syndrome, autoimmune hepatitis, IgA nephropathy, inflammatory myositis, primary-progressive multiple sclerosis, systemic lupus erythematosus, and ulcerative colitis. Finally, mixed results were reported for membranous nephropathy, primary Sjögren's syndrome and Graves' disease, therefore warranting better quality trials with larger patient numbers.
