With the continued development of noninvasive therapies for basal cell carcinoma (BCC) such as photodynamic therapy and immune therapies, noninvasive diagnosis and monitoring become increasingly relevant. High-definition optical coherence tomography (HD-OCT) is a high-resolution imaging tool, with micrometre resolution in both transversal and axial directions, enabling visualization of individual cells up to a depth of around 570 μm, and filling the imaging gap between conventional optical coherence tomography (OCT) and reflectance confocal microscopy (RCM). ⋯ Using features already suggested by RCM and conventional OCT, the study implies that HD-OCT facilitates in vivo diagnosis of BCC and allows the distinction between different BCC subtypes for increased clinical utility.

Randomized Controlled Trial Multicenter Study
Efficacy and safety of tofacitinib, an oral Janus kinase inhibitor, in the treatment of psoriasis: a Phase 2b randomized placebo-controlled dose-ranging study.
Tofacitinib is a novel, oral Janus kinase inhibitor under investigation as a potential treatment for plaque psoriasis. ⋯ Short-term treatment with oral tofacitinib results in significant clinical improvement in patients with moderate-to-severe plaque psoriasis and is generally well tolerated.

The scalp is commonly associated with itch and burning sensations. Previous studies have shown the scalp is highly innervated compared with other body areas. However, limited data are available on sensory testing associated with C nerve fibres of the healthy scalp. ⋯ This study demonstrates a significant insensitivity of C nerve fibres of the scalp to warmth, heat pain, itch and neurogenic inflammation. These results suggest that the scalp has an aberrant response of C nerve fibres.
