The prevalence of itch is higher in individuals with darker skin types. In this paper, we review the systems involved in the physiology of itch and how they may differ across the races. Current data point out that the differences may be explained by barrier function, mast cell physiology, and itch receptor polymorphisms.

Chronic kidney disease (CKD) is a global health concern, with a 10% global prevalence. Its prevalence may further increase in the coming decades, thereby increasing the risk of uremic xerosis. Approximately 50-90% of patients with CKD have xerosis, leading to pruritus that affects their quality of life due to sleep disturbances, anxiety, and depression.

AT2 dysfunction underlies many lung diseases, including interstitial lung disease (ILD), in which some inherited forms result from the mislocalization of surfactant protein C (SFTPC) variants. Lung disease modeling and dissection of the underlying mechanisms remain challenging due to complexities in deriving and maintaining human AT2 cells ex vivo.

Erythroderma is a severe and heterogeneous inflammatory skin condition with little guidance on the approach to management in cases of unknown etiology. To guide therapeutic selection, we sought to create an immunophenotyping platform able to identify aberrant cell populations and cytokines in subtypes of erythroderma. We performed high-parameter flow cytometry on peripheral blood mononuclear cells (PBMCs) and whole blood of a patient with refractory idiopathic erythroderma, erythrodermic patients with Sézary syndrome and pityriasis rubra pilaris, and healthy controls.

Background: Exposure to hairs of caterpillars and moths are collectively termed as lepidopterism. Clinical manifestations include cutaneous presentation of localized stinging reaction with wheals or vesiculation, acute urticarial papules and plaques, ophthalmic, oropharyngeal involvement to severe life-threatening anaphylactic reactions with angioedema.
Aims: In this study we have determined the prevalence of various cutaneous, oropharyngeal and ophthalmic manifestations of lepidopterism at a tertiary health care center.
