Behcet's disease (BD) is an autoimmune disorder that affects the blood vessels and thus could entangle virtually every organ of the body. Oral ulceration, genital aphthous lesions, and ocular inflammation are the main manifestations of the disease that tend to have a chronic, relapsing-remitting course. The disease comes from an association between environmental and genetic backgrounds. The clustering of cases in families and the high rate of co-occurrence of the disease in siblings were the initial findings that proposed a genetic basis for BD. Later on, multiple case-control studies and genome-wide association studies were able to clarify particular genes included in the etiopathogenesis of BD. The major gene polymorphisms include HLA and HLA-related genes, interleukins, and other genes involved in inflammation and transcription activation. Herein we have summarized the susceptibility genes that are associated with BD. Investigations on the genetics of BD could potentially clarify the disease pathogenesis and provide insights for the development of better treatments.

Non-infectious granulomatous skin diseases are a wide category of well-defined reactive inflammatory conditions that share main similarities. While cutaneous sarcoidosis is the prototype of non-infectious (sterile) granulomatous dermatitides, there are several other entities in this group including granuloma annulare and necrobiosis lipoidica. Non-infectious granulomatous diseases are caused by complex associations between genetic situations and environmental triggers resulting in a variety of cutaneous and systemic manifestations. The genetic backgrounds of these diseases are the main topic of this manuscript.

Systemic sclerosis (SSc) is a rare disease with a prevalence ranging from 7 to 700 cases per million. Like with most autoimmune diseases, both environmental and genetic factors are involved in the pathogenesis of the SSc. Though the incidence of SSc in the family members of those affected and the concordance rate in twins is very low, inheritance is still the strongest risk factor of SSc. Thus, multiple studies have been conducted to identify the genes responsible for this inheritance including candidate gene association studies and genome-wide analyses. Variations and mutations in the genes encoding cytokines, adhesion molecules, and signaling proteins involved in the interaction between endothelial cells, fibroblasts, and immune cells have been found to be associated with SSc susceptibility. In this chapter, these genes and their contribution to the pathogenesis of the SSc are discussed in detail. These genes are categorized into five major groups of HLA genes, genes involved in the innate immune responses, genes affecting adaptive immune responses, genes with a role in the fibrogenesis pathways, and apoptosis, autophagy, and pyroptosis-related genes.

Lupus erythematosus (LE) is a heterogeneous disease with a wide range of manifestations ranging from localized lesions in cutaneous lupus erythematosus (CLE) to severe disseminated disease in systemic lupus erythematosus (SLE).Lupus results from a complex interaction between genetic and epigenetic backgrounds and environmental triggers that cause loss of tolerance to self-antigens and the formation of autoantibodies. Genetic susceptibility plays a key role in the pathogenesis of lupus erythematosus. In most cases, multiple common alleles with modest effect sizes are combined to result in the polygenic inheritance of the disease but monogenic variants of lupus have also been described. Genes from the innate and adaptive immune system along with genes involved in apoptosis and immunoglobulin clearance have been linked to SLE. This chapter aims to explore the functions of these genes and their contribution to the pathogenesis of the disease.

BACKGROUND: Irritable bowel syndrome (IBS) is a functional gastrointestinal disorder in which one experiences abdominal pain, tension, cramping, bloating, and changes in the form and frequency of defecation, without an underlying organic disease. Many skin diseases have been reported to be more common in people with functional bowel disease. To our knowledge, however, no previous study investigated the potential relationship between hidradenitis suppurativa (HS) and IBS. In this study, we aimed to examine the potential association between IBS and HS. METHODS: Patients with HS and healthy subjects were enrolled in this cross-sectional study. All participants were assessed for the presence of IBS. ROME IV criteria were used to identify IBS cases. Hurley staging, modified Sartorius score, and physician's global assessment score were applied to define clinical severity and staging of HS. RESULTS: According to the Rome IV diagnostic criteria, 54 (67.50%) of 80 HS patients and 23 (28.75%) of 80 control group were diagnosed with IBS. The frequency of IBS was statistically significantly higher in the patient group than in the control group (P < 0.001). No statistically significant difference was found between the two groups in terms of abnormal stool frequency and family history of IBS (P = 0.28, P = 0.862, respectively). Abnormal stool form, mucus in stool, abdominal distension, feeling of incomplete evacuation were statistically significantly higher in HS patients compared to the controls (P = 0.01, P = 0.02, P < 0.001, P = 0.001, respectively).

Human papillomavirus infection is relatively common in communities. Thus, determining an effective and painless treatment method, especially in pediatric patients is of utmost importance. This study aimed to compare the outcomes of three different methods of treating plantar warts in pediatric patients. Children with verruca plantaris treated with a salicylic acid-lactic acid combination once daily (SA/LA 1), a salicylic acid-lactic acid combination applied in three to seven layers under occlusion every 3 days (SA/LA 2), or a combination of 5-fluorouracil (0.5%) and salicylic acid (10%) (SA/5-FU) were evaluated retrospectively. Treatment responses and recurrence rates were also evaluated after a minimum of 4 months. Among the 98 children with verruca plantaris, 19 were treated with SA/LA 1, 53 were treated with SA/LA 2, and 18 were treated with SA/5-FU; the eight patients who received cryotherapy were excluded. The mean treatment duration was significantly shorter in the SA/LA 2 group than in the SA/LA 1 group and the SA/5-FU group. (p = 0.000 for both) Application of a salicylic acid-lactic acid combination in multiple layers under occlusion is a safe, painless, and effective treatment method for plantar warts in children.

Cutaneous leishmaniasis is caused by a flagellated protozoan transmitted by the bite of a female sandfly. The clinical and demographic details of this disease, predominantly affecting immunocompetent individuals, are recognized by the WHO as a Neglected Tropical Disease. We sought to determine the usability of CD1a immunohistochemical staining to detect amastigotes especially in cases where leishmaniasis is suspected but evident amastigotes could not observed. We also evaluated the relationship between CD1a expression and leishmania subtypes. A total of 84 cases diagnosed with leishmaniasis or suspected leishmania on histo-morphological evaluation of skin biopsies were included in the study. Amastigotes were easily detected in hematoxylin eosin in 18 of 84 cases. In 23 cases, amastigotes could not detect in hematoxylin eosin sections. The immunostains for CD1a are demonstrated amastigotes in 60 of 84 cases. However, a small number of amastigotes became visible by positive staining with CD1a in 43.4% of the cases in that amastigotes could not detected in hematoxylin eosin. A statistically significant correlation was found between amastigote amount in hematoxylin eosin and CD1a expression. In addition, a significant correlation was observed between CD1a expression, age and clinical pre-diagnosis of the cases. It was observed that amastigotes were easily detected in hematoxylin eosin in Leishmania Infantum / donovani positive cases in polymerase chain reaction (PCR), and at the same time, it was found that CD1a expression was significantly higher. Using histopathology examination with CD1a staining and/or PCR methods, a diagnosis of leishmaniasis can be established and early treatment initiated. This contributes to reduce transmission and prevalence.

COVID-19 is a multisystem disease caused by severe acute respiratory syndrome coronavirus 2. It has been declared a pandemic by the World Health Organization in March 2020 and the outbreak still keeps its impacts worldwide. Behçet disease (BD) is a multi-systemic vasculitis involving the skin, mucosa, eyes, joints, nervous system, cardiovascular system, and gastrointestinal system. The precise etiopathogenesis of the disorder is unknown but autoimmunity is believed to play a key role. A considerable part of patients with BD are susceptible to immunosuppression and are more predisposed to infections than healthy individuals. Hence, the protection and control measures for patients with BD against the COVID-19 are of the utmost significance. Given the requirement to balance proper treatment of BD with the smallest risk of COVID-19 associated mortality and morbidity, we aimed to review the management of BD in the era of the pandemic with a special focus on treatment considerations. According to current expert recommendations, there is no reason to discontinue topical treatments, colchicine, and nonsteroidal antiinflammatory drugs. Systemic steroids can be used at the lowest possible dose if needed. Ongoing treatments can be continued unchanged in patients with no suspected or confirmed COVID-19. In cases with COVID-19 symptoms, immunosuppressive and biological agents can be temporarily stopped but the decision should be made on a case by case basis. Considering their potential beneficial effects on the course of COVID-19, colchicine, pentoxifylline, and dapsone can be considered as safe treatment options in BD.

OBJECTIVES: Onychomycosis is the general term to define fungal nail infections that arise from dermatophytes, non-dermatophytic moulds and yeasts. Thiol/disulphide homeostasis is a new indicator of oxidative stress. In this study, we aimed to investigate the role of thiol/disulphide balance in the pathogenesis of onychomycosis. METHODS: This cross-sectional study included adult patients with onychomycosis who were admitted to the dermatology department and healthy adult volunteers without any dermatologic or systemic condition. The patients and controls were evaluated in terms of native thiol, total thiol, and disulphide levels, and disulphide/native thiol, disulphide/total thiol and native thiol/total thiol ratios. The possible association between these parameters and clinical subtypes of onychomycosis and demographic characteristics was also investigated. RESULTS: A total of 52 patients with onychomycosis and 50 healthy subjects were enrolled in the study. The patient group showed lower levels of total thiol, native thiol and native thiol/total thiol ratio, and higher ratios of disulphide/native thiol and disulphide/total thiol. No statistically significant relationship was found between the parameters, clinical subtypes of onychomycosis and demographic characteristics (p > .05). CONCLUSION: Patients with onychomycosis showed a shifted thiol/disulphide homeostasis towards oxidative stress with a reduction in thiols and an increase in disulphide/native thiol, and disulphide/total thiol ratios. These findings may indicate the role of oxidative stress in the pathogenesis of onychomycosis.

Background/aim: Chitotriosidase (ChT) is an enzyme secreted by activated macrophages and neutrophils in response to proinflammatory signals. There is growing evidence indicating that ChT activity reflects the systemic inflammatory status. This study aimed to investigate whether serum ChT activity increased in patients with psoriasis and related comorbidities. Materials and methods: This cross-sectional study included 53 (28 with associated comorbidities and 25 without comorbidities) patients with psoriasis and 52 healthy volunteers. All participants underwent laboratory investigations for serum ChT levels, complete blood count, erythrocyte sedimentation rate, C-reactive protein, and serum lipid levels. Results: The patients with psoriasis showed significantly higher levels of ChT activity as compared to the healthy controls (23.5 ± 11.4 vs. 17.5 ± 10.4 µmol/mL/hour; p = 0.015). Additionally, the ChT activity was significantly higher in patients with comorbidities than in those without (p = 0.042). Conclusion: Our data support the pathogenetic role of inflammatory processes induced by macrophage activation in patients with psoriasis and related comorbidities. We believe that high ChT activity in patients with psoriasis may serve as an early prediction of the possible related comorbidities.

COVID-19 is a highly contagious respiratory tract infection caused by severe acute respiratory syndrome coronavirus 2. COVID-19 outbreak, which caused thousands of deaths, has been declared a pandemic by the World Health Organization in March 2020. The infection has been reported to demonstrate different types of cutaneous manifestations including urticarial, maculopapular, papulovesicular, purpuric, livedoid, and thrombotic-ischemic lesions. Given the high mortality rate of the infection, timely and accurate identification of relevant cutaneous manifestations may play a key role in the early diagnosis and management. In this study, we provide a review with a focus on the reported cutaneous manifestations of COVID-19.

COVID-19 is a serious multisystem disease caused by severe acute respiratory syndrome coronavirus 2. Due to the COVID-19 crisis, that still keeps its impacts worldwide, numerous scheduled medical activities have been postponed and this interruption has a potential to modify the management of many cutaneous conditions including pemphigus. This narrative review aims to discuss the management of pemphigus in the era of COVID-19, considering the necessity to balance suitable pemphigus treatment with minimal risk of COVID-19-related mortality and morbidity. The data on the effect of treatments used for pemphigus on COVID-19 are limited. However, the evidence to manage patients properly is evolving and our knowledge is updated. Current expert recommendations include that patients with pemphigus should be informed clearly to avoid mismanagement and they should be monitored regularly for symptoms of COVID-19. Patients with mild disease can be managed with topical or intralesional corticosteroids, dapsone, or doxycycline. Systemic corticosteroids should be tapered to the lowest effective dose during the pandemic. Prednis(ol)one ≤10 mg/d can be continued in patients with COVID-19 while prednis(ol)one >10 mg/d may be reduced considering the activity of the disease. Conventional immunosuppressive therapies should only be discontinued in confirmed cases of COVID-19. Postponing rituximab treatment should be considered on a case by case basis. Intravenous immunoglobulin is not likely to increase the risk of infection and may be considered a safe option in patients with COVID-19. Given the psychological burden brought by COVID 19, online or face-to-face psychological support programs should be considered.

Cutaneous manifestations of COVID-19 disease have not yet been fully described. To describe cutaneous manifestations of COVID-19 disease in hospitalized patients. We examined the cutaneous manifestations of 210 hospitalized patients. Cutaneous findings were observed during COVID-19 infection in 52 of the patients. Lesions may be classified as erythematous scaly rash (32.7%), maculopapular rash (23%), urticarial lesions (13.5%), petechial purpuric rash (7.7%), necrosis (7.7%), enanthema and apthous stomatitis (5.8%), vesicular rash (5.8%), pernio (1.9%), and pruritus (1.9%). Cutaneous manifestations were observed statistically significantly more in certain age groups: patients of 55 to 64 and 65 to 74 years of age complained of more cutaneous manifestations than the other age groups. As for gender, there was no significant difference between male and female patients in terms of cutaneus findings. The relationship between comorbidity and dermatological finding status was statistically significant. The relationship increases linearly according to the comorbidities. According to the statistical results, the patients who were hospitalized in the intensive care unit had a higher risk of having cutaneous findings due to COVID-19 infection. With this study, we may highlight the importance of overlooked dermatological findings in patients that are hospitalized.

Melanoma is the most severe form of skin cancer and its incidence has increased over the past few decades. COVID-19 pandemic affected the diagnosis and management of many diseases including melanoma. In this study, we aimed to provide a review focused on the diagnosis and management of melanoma in the era of COVID-19. A comprehensive search was conducted on PubMed, Web of Science, and Google Scholar databases using the keywords "melanoma," "coronavirus," "COVID 19," and "SARS-CoV-2." The relevant guidelines published by the European Society for Medical Oncology and the National Comprehensive Cancer Network were also included. The current guidelines recommend that surgical interventions for new diagnosis of invasive primary melanoma, patients with postoperative complications, wide resection and sentinel lymph node biopsy for newly diagnosed T3-T4 melanoma, and planned surgical procedures for patients in neo-adjuvant trials should be prioritized. Surgical treatment of T3/T4 melanomas should be prioritized over T1/T2 melanomas except for any melanoma in which large clinical residual lesion is visible. Adjuvant therapies can be postponed for up to 12 weeks depending on the local center circumstances. PD-1 inhibitor monotherapy is recommended for patients starting immunologic therapy. Combination immunotherapy is still considered suitable for patients with higher-risk disease. Encorafenib and binimetinib should be prioritized for patients requiring BRAF-targeted therapy due to the lower chance of symptoms mimicking COVID-19 infection.

Coronavirus disease (COVID-19) is a highly contagious respiratory infection caused by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). COVID-19 outbreak has been declared a pandemic by the World Health Organization on March 2020. The pandemic has affected the management of psoriasis not only for those who are under treatment but also for those who are about to begin a new therapy to control their disease. An increasing number of studies in the current literature have focused on the relationship between psoriasis and COVID-19 from different perspectives. This narrative review includes searching the PubMed and Web of Science databases using the keywords "psoriasis," "psoriatic arthritis," "coronavirus," "COVID-19," and "SARS-CoV-2." The search was supplemented by manual searching of reference lists of included articles. A total of 11 relevant original investigations and 6 case studies was identified. The search was updated in May 2019. Due to the absence of randomized controlled trials, it is not likely to have a robust evidence-based approach to psoriasis management in the era of COVID-19. However, the current literature may provide some clues for safety considerations. Conventional immunosuppressive therapies such as methotrexate and cyclosporine, and anti-tumor necrosis factor agents should not be preferred due to increased risk of infection, especially in high-risk areas. The use of cyclosporine may pose additional risk due to the side effect of hypertension, which has been reported to be associated with susceptibility to severe COVID-19. Considering that the current literature has provided no conclusive evidence that biologics increase the risk of COVID-19, withdrawal of these agents should be reserved for patients with COVID-19 symptoms. The treatment approach should be personalized, considering the advantages and disadvantages for each case separately.
