The effect of dipeptidyl peptidase-4 inhibitor on incidence and clinical course in bullous pemphigoid patients in a tertiary medical center.

Several studies have reported an association between dipeptidyl peptidase 4 inhibitor (DPP4i), a commonly prescribed second-line oral antihyperglycemic drug, and bullous pemphigoid (BP). However, the benefits of DPP4i withdrawal in patients with BP remain controversial. This study primarily aimed to evaluate the clinical severity of DPP4i-associated BP by comparing it to those without Type 2 diabetes mellitus (DM).

Response predictor for pigment reduction after one session of photo-based therapy using convolutional neural network: A proof of concept study.

Background: Identifying treatment responders after a single session of photo-based procedure for hyperpigmentary disorders may be difficult.

Objectives: We aim to train a convolutional neural network (CNN) to test the hypothesis that there exist discernible features in pretreatment photographs for identifying favorable responses after photo-based treatments for facial hyperpigmentation and develop a clinically applicable algorithm to predict treatment outcome.

Methods: Two hundred and sixty-four sets of pretreatment photographs of subjects receiving photo-based treatment for esthetic enhancement were obtained using the VISIA® skin analysis system.

The impact of the COVID-19 surge on phototherapy in Taiwan: Focusing on the patient profile, adherence, and attitude before and after the surge.

Background: Coronavirus disease 2019 (COVID-19) pandemic has caused changes in the medical practice. However, it is unclear whether the patients receiving phototherapy for their dermatoses have been affected.

Objectives: This study aimed to identify the impact of the COVID-19 pandemic on phototherapy, focusing on the patient profile, adherence, and attitude before and after the surge.

Impact of Vitiligo on Life Quality of Patients: Assessment of Currently Available Tools.

Background: How different tools for evaluating health-related quality of life (QoL) reflect the burden of vitiligo has rarely been compared. In this study, we aim to evaluate the impact of vitiligo on QoL using currently available tools.

Methods: A single-center, cross-sectional study of vitiligo patients was performed.

Taiwanese dermatological association consensus for the definition, classification, diagnosis, and management of urticaria: A 2021 update.

Urticaria is a prevalent disease with substantial physical, psychological, and economic impacts. With the advent of understandings of the disease and the emerging evidence of treatments, the international guidelines for treating urticaria have been updated in recent years. In order to update the 2014 edition of the Taiwanese Dermatological Association (TDA) consensus of urticaria, a total of 17 dermatologists with extensive experience in urticaria management were invited to and attended the TDA consensus meetings.

Favorable effect after single treatment session of 755-nm-picosecond laser with a diffractive optic lens on facial wrinkles and pore size in Asians.

Objectives: Laser therapy has become one of the mainstay treatments for improving signs of aging including wrinkles, large pores, and skin pigmentation. However, in patients with pigmented skin, an increase in complications including post-inflammatory hyperpigmentation (PIH) has been noted. The purpose of this study is to investigate not only the safety profile of 755-nm picosecond laser with diffractive lens array (DLA) at approximately 2250 pulses on the face in people with darker skin, but also to evaluate its efficacy in treating wrinkles and pore sizes after one treatment session among different age groups.
