Melasma is an acquired pigmentation disease that mainly involves the development of symmetrical yellow-brown facial patches. The incidence rate increasing yearly. Therefore, actively studying exposure factors induce melasma could contribute to prevention and treatment this disease. In present review, possible were summarized.

Hidradenitis suppurativa (HS) is a multifactorial chronic skin disease characterized by inflammation around the hair follicles commonly affecting intertriginous areas. The underlying pathogenesis of HS and its molecular mechanisms are largely understudied. Genetic studies in families have identified variants within γ-secretase complex associated with HS; however, no definitive genotype-phenotype correlations been made. lack knowledge regarding intersection genetics, immunology environmental...

Introduction: Dry eye disease (DED) is an important public health problem considering its prevalence, morbidity, and cost implications. In the last two decades, new insight on pathogenesis of dry has resulted in development novel therapeutic modalities.Areas covered: This review will discuss current emerging pharmacological modalities treatment DED to include tear supplements, anti-inflammatory therapy, antibiotics, vitamin A, other vitamins antioxidants, free amino acids, essential fatty...

Hidradenitis suppurativa (HS), psoriasis, and vitiligo are chronic, immune-mediated skin diseases with a significant quality-of-life burden. Individuals these conditions thought to be at increased risk of lymphoma,1-3 several cases have been reported in the context adalimumab treatment, raising concern for its use at-risk patients. The specific mechanisms underlying link between chronic inflammatory states neoplastic transformation largely unknown, most data on topic come from outside...

Abstract Hidradenitis suppurativa (HS), an inflammatory skin-disease, manifests as painful lesions in intertriginous skin. Despite their central role innate immunity the of monocytes HS is largely unknown. Here we utilized cytometry by time-of-flight (CyTOF), imaging CyTOF (IMC), cellular indexing transcriptomes and epitopes sequencing (CITEseq), spatial transcriptomics (ST), our recently developed database (HSOmicsDB) to characterize systemic cutaneous immune response patients with HS....

The incidence of oropharyngeal cancer (OPC) has increased in the United States. This been driven by an increase human papillomavirus (HPV)-positive OPC. Our objective is to determine trends National Institutes (NIH)-supported research funding and public interest OPC.The NIH Research Portfolio Online Reporting Tools database was evaluated for projects related OPC between 2004 2015. Projects were total funding, relation HPV, principal investigator departmental affiliation degree, agency or...

Background Postinflammatory hyperpigmentation (PIH) is a common, acquired pigmentary disorder of the skin associated with significant quality-of-life impairment, especially in individuals colour. Current treatment for PIH limited, largely due to poor understanding disease pathogenesis and lack representative model. Objectives This study intended further develop, update validate our previously designed vivo model acne-induced PIH/postinflammatory erythema (PIE) using different concentrations...

Abstract: Microsecretory adenocarcinoma (MSA) was first described in 2019 as a low-grade salivary gland neoplasm of intraoral origin with distinct histopathologic features and characteristic MEF2C::SS18 fusion. Recently, skin also identified primary site for MSA report by Bishop et al. Due to its rarity resemblance other adnexal tumors, is challenging diagnosis. Herein, we present case cutaneous that unique the presence significant microcystic component marked hyperplasia, which mimicked...

Introduction: Dry eye disease (DED) is a multifactorial condition of the tears and ocular surface. New insight on pathogenesis dry has resulted in development novel treatments. Current management paradigms vary from self-administered (e.g. artificial tears) to practitioner-administered punctal occlusion) modalities.Areas covered: In part A this series, spectrum pharmacological agents for treatment DED was reviewed. Part B discusses current emerging non-pharmacological therapeutic modalities,...
