Evaluation of demographic and clinical characteristics of 728 patients with mycosis fungoides and their relationship with systemic comorbidities: multicenter, registry-based (MF-TR) study from Türkiye.

Background: Mycosis fungoides (MF) is the most common cutaneous lymphoma with a chronic disease course. MF patients may also suffer from systemic comorbidities such as cardiovascular and metabolic diseases.

Methods: In this study, we aimed to evaluate the demographic and clinical features of MF patients registered in the MF-TR registry system and to examine the relationship of these features with systemic comorbidities.

Evaluation of the Factors Influencing Mortality in Patients with Stevens-Johnson Syndrome and Toxic Epidermal Necrolysis: A Multicenter Study of 166 Patients.

Introduction: Stevens-Johnson syndrome (SJS) and toxic epidermal necrolysis (TEN) are life-threatening acute mucocutaneous disorders usually triggered by drugs. In this study, we aimed to evaluate the factors affecting mortality in patients with SJS-TEN.

Methods: Our study is a retrospective cohort study, analyzing data collected from a total of 12 tertiary care centers between April 2012 and April 2022.

Analysis of clinical characteristics and factors affecting treatment responses in patients with pyoderma gangrenosum: a multicenter study of 239 patients.

Background: Pyoderma Gangrenosum (PG) is a chronic disease characterized by recalcitrant skin ulcers.

Objective: We aimed to evaluate the demographic, clinical characteristics, treatments and factors affecting the treatment responses of patients with PG.

Methods: We performed a multicenter study of 12 tertiary care centers.

Methyl(chloro)isothiazolinone contact allergy: a monocentric experience from Turkey.

Introduction: Due to their ubiquitous use, isothiazolinones caused allergic contact dermatitis epidemics and their use was restricted by legal regulations.

Objectives: We aimed to evaluate demographic data, clinical findings, and patch test features of patients with methylisothiazolinone (MI) and/or methylchloroisothiazolinone(MCI) sensitivity in our study.

Methods: This study is a bidirectional and cross-sectional study, between July 2020 and September 2021.

Could there be an association between Hashimoto's thyroiditis and demodex infestation?

Background: Human demodex mites are parasites that live in the pilosebaceous unit and can result in the disease demodicosis. While demodicosis may occur as a primary skin disease; immunosuppression, and topical or systemic immunosuppressive treatments can cause secondary demodicosis. It is known that thyroid hormones may cause skin changes, such as xerosis, and thereby may also modulate immune responses in the skin.

Multicenter study evaluating the impact of COVID-19 outbreak on dermatology outpatients in Turkey.

COVID-19 pandemic has a significant impact on public health, whether directly or indirectly. The first case was seen in Turkey on March 11, and the World Health Organization (WHO) declared a pandemic on March 12, 2020. The study aimed to document the effect of pandemic on dermatology outpatient clinics in Turkey.

Imiquimod 5% Cream Versus Cryotherapy in Classic Kaposi Sarcoma.

Background: Classic Kaposi sarcoma usually remains on the skin and has a slow progression; thus, local treatment methods are preferable. Imiquimod is an immunomodulatory agent with antiviral, antitumoural, and antiangiogenic properties that is expedient against Kaposi sarcoma.

Objectives: We aimed to clarify whether imiquimod is effective on classic Kaposi sarcoma lesions by comparing imiquimod treatment with cryotherapy, which is the most-used treatment method in our department for this disease.

A Rare Cause of Leg Ulcer: Calcinosis Cutis as a Part of CREST Syndrome.

Leg ulcers are not a disease themselves, they are a symptom of a disease. To manage them properly, finding the correct diagnosis of the disease is mandatory. Our case is a model to underline that leg ulcers are a significant burden for the patient, because leg ulcer got ahead of the patient's other serious complaints such as Raynaud's phenomenon or sclerodactyly.

TNF-alpha inhibition prevents cognitive decline and maintains hippocampal BDNF levels in the unpredictable chronic mild stress rat model of depression.

Previous findings have shown that patients with depression express higher levels of proinflammatory cytokines such as TNF-α and IL-6. We have recently found that Infliximab (a TNF-α inhibitor) decreased anhedonia and despair-like behavior in the rat unpredictable chronic mild stress (UCMS) model of depression suggesting that inflammation might play an important role in depression. An increasing number of studies suggest that inflammation is also associated with cognitive impairments.

Blastic plasmacytoid dendritic cell neoplasm: skin and bone marrow infiltration of three cases and the review of the literature.

Blastic plasmacytoid dendritic cell neoplasm (BPDCN) is a distinct and rare neoplastic entity and was classified as a subgroup of acute myeloblastic leukemia by the WHO in 2008. The median survival of patients was 15.2 months in a large case series.

Etanercept improves cognitive performance and increases eNOS and BDNF expression during experimental vascular dementia in streptozotocin-induced diabetes.

Diabetes mellitus (DM) is related to an increase in the incidence of vascular dementia. Inflammation is an important cause of endothelial dysfunction and cognitive deficits. The anti -tumor necrosis factor (TNF)-α fusion protein etanercept has been reported to exhibit memory-enhancing effects and endothelial protection.

Symmetrical drug-related intertriginous and flexural exanthema (SDRIFE) induced by oral metronidazole.

Baboon syndrome is a special form of systemic contact dermatitis to systemic or local administration of contact allergens. Baboon syndrome without known previous cutaneous sensitisation was also described as drug-related baboon syndrome or symmetrical drug-related intertriginous and flexural exanthema (SDRIFE). The major drugs causing SDRIFE was beta-lactam antibiotic such as amoxicillin and ampicillin.

Proteus syndrome: report of a case with developmental glaucoma.

The purpose of this study was to report developmental glaucoma and pseudopapilledema in a patient with Proteus syndrome. We defined the presence of developmental glaucoma, right pseudopapilledema and myopia in a 4.5-year-old patient with Proteus syndrome.

The link between unpredictable chronic mild stress model for depression and vascular inflammation?

Inflammation has been suggested to be associated with stress-induced depression and cardiovascular dysfunction. Tumor necrosis factor alpha (TNF-α) is a major cytokine in the activation of neuroendocrine, immune, and behavioral responses. In this study, we investigated the effects of infliximab (a TNF-α inhibitor) on endothelium-dependent vascular reactivity, systemic blood pressure, and endothelial nitric oxide synthase (eNOS) immunoreactivity in the unpredictable chronic mild stress (UCMS) model of depression in rats.
