This review discusses the effects of valproic acid on immune cell activation and gene expression, potentially influencing infection outcomes and suggesting its promise for autoimmune and hypersensitivity condition management.

This study identified the presence of apoptotic or necrotic keratinocytes and hair shaft dystrophy as potential markers of hair loss in patients with HIV-1 infection.

This study suggests that spiny keratoderma may be an ectopic hair formation on palms and soles, based on keratinization patterns observed using antikeratin antibodies and electron microscopy.

This case report details a 37-year-old man who developed eosinophilic pustular dermatosis after previously resolving herpes zoster, with successful treatment using itraconazole and cycloproxolamine.

In this study, treating refractory alopecia universalis with low-dose cyclosporine A and prednisolone improved symptoms, with no recurring alopecia six months post-treatment and enhancements in immunologic function.

This study suggests that hypersensitivity and increased serum IgE levels might contribute to the pathogenesis of diffuse alopecia areata through intense local inflammatory infiltration.

This review highlights the possible role of T regulatory cells in the immune-related mechanisms of alopecia areata but reports no new clinical findings.

Early stage bald spots are linked to skin inflammation and damage to the upper part of the hair follicle.

This study found that Rumex japonicus extract may help reduce symptoms of atopic dermatitis by inhibiting inflammatory responses in both cell cultures and a mouse model.

This study found that adnexal acantholysis does not reliably distinguish pemphigus vulgaris from pemphigus foliaceus, but the level of acantholysis and degree of dyskeratosis serve as distinguishing features among acantholytic disorders.

This study found that the alcoholic extract of Eclipta alba exhibited dose-dependent antianaphylactic effects in animal models, possibly due to membrane stabilization and reduced histamine release.

This notice provides information about JAMA Dermatology's website usage policy, and no research findings are reported.

This report describes common cutaneous reaction patterns in cats with non-flea induced hypersensitivity dermatitis but does not provide new experimental findings or results.

This study concludes that tiny infundibular cysts, rather than comedones, are the primary lesions in chloracne.

This case study describes a cat with concurrent cutaneous xanthomas, demodicosis, and dermatophytosis, which suggests potential primary hyperlipidaemia as the underlying cause for its symptoms.

Minoxidil can cause pustular allergic reactions on skin.

This study found that scalp involvement in dermatomyositis consistently shows a nonscarring pattern with chronic telogen effluvium, featuring telangiectasia and mucin deposition as universal histologic markers.

This study concluded that Aloe vera fermentation significantly accelerates burn injury healing in rats by reducing inflammation and altering gut microbiota composition.

This case report describes a patient with psoriasis who developed alopecia with unique histological features after anti-TNF therapy, suggesting that such effects may require considering treatment suspension for severe cases.

This case report describes the first known instance of congenital follicular mucinosis in a newborn, diagnosed through histopathological examination of a scalp lesion.
