Metastatic Merkel Cell Carcinoma After Simultaneous Pancreas-Kidney Transplantation: Fatal Outcomes.

Merkel cell carcinoma (MCC) is a rare, highly aggressive cutaneous malignancy. Immunosuppression increases the risk of MCC and is associated with poor prognosis. Organ transplant recipients (OTR) have worse overall survival (OS) than patients with immunosuppression due to other causes.

Emerging treatments for itch in atopic dermatitis: A review.

Atopic dermatitis is a chronic inflammatory skin condition with a high prevalence that is increasing. The most universal symptom in patients with atopic dermatitis is pruritus; it is often the most troublesome symptom. New insights on the mechanism of itch in patients with eczema have been elucidated, involving cross-talk between neural and immune systems, which have advanced our treatments significantly.

The effect of fatty acids, vitamins, and minerals on pediatric atopic dermatitis: A systematic review.

Background: A body of research has examined the role of fatty acid (FA), vitamin, and mineral supplementation as adjunctive treatment for atopic dermatitis (AD); however, results are conflicting and concrete recommendations are lacking. The objective of this study is to highlight the role of these nutrients in alleviating AD severity and provide the clinician with consolidated information that can be used to make recommendations to the pediatric patient and caretaker, where this topic is of high interest.

Methods: A review of the PubMed and Embase databases was conducted to identify and qualitatively analyze all randomized controlled trials, systematic reviews, and meta-analyses conducted within the last 21 years regarding use of these nutrients to alleviate symptoms of AD.

Evaluation of risk in chronic cutaneous inflammatory conditions for malignant transformation.

Skin carcinomas are the most common form of cancer, and every year thousands of people die from skin cancer-related malignancies. Chronic inflammation is linked to the development and progression of cancer in multiple organ systems - about 20% of all human cancers are a result of chronic inflammation - skin included. While acute inflammation under normal circumstances is a mechanism for host defence and tissue regeneration following insult by trauma or infection by pathogens, over the long term it can drive oncogenic transformation of epithelial cells and promote cancer development, growth and metastasis.

Update on mosquito bite reaction: Itch and hypersensitivity, pathophysiology, prevention, and treatment.

Mosquito bites are endured by most populations worldwide. Reactions to mosquito bites range from localized wheals and papules with associated pruritus to rare systemic reactions and anaphylaxis in certain populations. The mechanism of itch is due to introduction of mosquito saliva components into the cutaneous tissue, although the exact pathophysiology is unclear.

Silicone barrier cream in treatment of atopic dermatitis: A literature review.

Atopic dermatitis (AD) is a complex skin disorder that requires multidisciplinary treatment modalities to best improve the results of the condition. Although silicone formulations have been used for the treatments of wounds, ulcers, and burns, we aim to highlight the use of a silicon solution for the treatment of eczema. Components of the silicone formula may enhance treatment for AD, such as in the wet wrap therapy, and can be a useful addition.

An evaluation of abrocitinib for moderate-to-severe atopic dermatitis.

Introduction: Atopic dermatitis (AD) is a common itchy inflammatory skin condition that affects many individuals. For many years, the landscape of AD treatment remained unchanged; however, there has been developing therapies that directly target the underlying immunological mechanism of AD. Janus kinase (JAK) inhibitors are small molecules that have shown anti-inflammatory and anti-itch effects in AD.

Immunotargets and Therapy for Prurigo Nodularis.

Prurigo nodularis is a chronic inflammatory skin disease consisting of severely pruritic nodules that can be very debilitating for patients. The basis of this skin condition is immunological dysregulation and neural amplification, driven by T-lymphocytes, mast cells, eosinophilic granulocytes, macrophages, and cytokines mediating itchy processes. Further complicating this already taxing diagnosis is the lack of approved treatment and consensus on management; although there are off-label treatments utilized as therapy.

Autoimmune Progesterone Dermatitis: A Systematic Review.

Autoimmune progesterone dermatitis (AIPD) is a cyclical, cutaneous reaction to endogenous progesterone that occurs throughout the menstrual cycle. The cutaneous manifestations of AIPD vary greatly from patient to patient, ranging anywhere from urticaria to erythema multiforme to anaphylaxis. As such, recognition, diagnosis, and management of this condition are difficult for clinicians.

Current Clinical Options for the Management of Itch in Atopic Dermatitis.

Pruritus is the most burdensome and prevalent symptom in patients suffering from atopic dermatitis. Treating atopic itch has historically been a challenge due to multiple underlying mechanisms within its pathogenesis and an incomplete understanding of them. In recent years, our understanding of these mechanisms have increased tremendously and subsequently, new treatments have reached the market that target the pathophysiology of atopic itch from different angles.

Melanoma in the setting of nevus of Ota: a review for dermatologists.

Nevus of Ota, also known as oculodermal melanocytosis or nevus fuscoceruleus ophthalmomaxillaris, is a benign dermal melanocytic nevus that most commonly affects Asian women. While the lesion is largely a cosmetic concern, it has the potential to undergo malignant transformation to melanoma. Patients with nevus of Ota often present to a dermatologist at some point for examination or removal with laser therapy.
