Atopic dermatitis (AD) is a chronic and multifactorial inflammatory skin disease involving various dendritic cells such as epidermal Langerhans cells (LC) and inflammatory dendritic epidermal cells (IDECs). Most of the clinical studies was performed on isolated cells, and thus, it would be useful to characterize directly on the human epidermal tissue the first cellular events occurred during the AD. The suction blister method was used to obtain whole epidermis samples and interstitial cutaneous fluids. Employing multiphoton microscopy, we analyzed the early dynamic behavior of inflammatory cells using Dermatophagoides pteronyssinus atopy patch test (Derp-APT) and evaluated the effects of emollient pre-application. Derp-APT application provoked rapid and strong infiltration of IDECs, and proliferation and activation of LC in the AD subjects' epidermis. Moreover, emollient pre-application strengthened the defective skin barrier and had positive effects on inflammatory cells' behavior, characterized by the complete inhibition of IDEC influx and the presence of immature LC.

Introduction: Bruton's tyrosine kinase (BTK) is a cytoplasmic signaling protein expressed across a variety of immune cells, terminally differentiated plasma cells, and natural killer cells. Due to the signal potential and targetable nature of BTK, the use of BTK inhibitors (BTKis) has been proposed for the management of several diseases. Currently, the use of BTKis is under investigations for several dermatological conditions such as pemphigus, systemic lupus erythematosus, hidradenitis suppurativa, atopic dermatitis, and chronic spontaneous urticaria (CSU).

Varicella-zoster virus (VZV) is a known cause of meningoencephalitis, typically in immunocompromised inpatients. We report a case of meningitis caused by VZV in an immunocompetent man in his 20s. Diagnosis was delayed due to the atypical presentation of painless occipital zoster mimicking atopic dermatitis, and the presence of hypoglycorrhachia in his cerebrospinal fluid.
