Background: Ultraviolet (UV) light may cause dermoscopic changes on melanocytic nevi (MN).
Objectives: To investigate the effects of sunscreen cream (SSc) application on dermoscopic changes in MN during narrowband UVB (NBUVB) therapy.
Methods: Half of the randomly selected MN in each patient were covered with opaque tape and SSc [SSc(+)], and the rest were covered with only opaque tape [SSc(-)] during NBUVB treatment sessions.
Results: More SSc(-) MN displayed dermoscopic changes at end of NBUVB therapy compared to the start of therapy (p=0.035). The number of the MN that decreased in size and showed loss of structure was significantly higher in SSc(-) MN (p=0.04 and p=0.026, respectively).
Conclusions: Sunscreen in combination with opaque tape may contribute to some dermoscopic changes in melanocytic nevi, including decrease in size and loss of structure.

Introduction: Endothelial damage is associated with acute and long-term coronavirus disease 2019 (COVID-19) complications. Proximal nailfold capillaries and nail beds give important clues to microvascular changes associated with endothelial dysfunction.
Objective: We aimed to use dermoscopy to examine the proximal nailfold capillaries and nail bed of COVID-19 patients and identify microvascular changes.
Unexpected Extensive Hair Whitening Following Baricitinib Treatment for Alopecia Universalis: A Case Report and Mechanistic Insights.

Alopecia universalis (AU) is a severe form of alopecia areata characterized by the complete loss of scalp and body hair. While Janus kinase (JAK) inhibitors like baricitinib have shown promise in promoting hair regrowth in severe cases of AU, unexpected side effects, such as hair depigmentation, have not been widely reported. We present the case of a young male with AU who experienced progressive and extensive whitening of his scalp and body hair following treatment with baricitinib.

Morphea is a chronic inflammatory fibrosing disorder. Since fibrosis is the hallmark of both scars and morphea, our attention was raised for the possible use of Fractional Ablative CO lasers and microneedling as treatment modalities for morphea. To compare the efficacy and safety of Fractional Ablative CO lasers and microneedling in the treatment of morphea.

Pregnancy-associated changes in melanocytic nevi (MN), apart from size increase on the trunk, remain a topic of debate. We conducted the first prospective study to investigate dermoscopic changes in MN comparing pregnant with non-pregnant women on all body parts using a market-approved convolutional neural network (CNN). We included 25 pregnant and 25 non-pregnant women from Basel, Switzerland, who underwent standard skin cancer screenings and whose MN > 2 mm were digitally recorded and analysed by a CNN.
