Background: A 14-year-old female rhesus monkey (Macaca mulatta) of Chinese origin has been suffering from alopecia universalis since childhood.
Methods: Recently, the health status of the animal was recorded comprehensively by detailed clinical examination including hematology and serology supplemented by histological and immunohistochemical investigations of skin biopsies and molecular biological techniques to clarify the causes of the persistent hair loss.
Results And Conclusions: The hairless gene (hr) nonsense mutation was ruled out by polymerase chain reaction and by sequencing of the corresponding gene. Histological examinations revealed a prominent chronic lymphocytic perifolliculitis and folliculitis affecting anagen stage hair follicles as well as miniaturized hair follicles. Immunohistochemistry using the antibodies CD3, CD20 and CD4 confirmed the diagnosis of a T-cell-mediated autoimmune disease resembling alopecia areata universalis in humans.

Vitiligo is an autoimmune disease characterized by the loss of functional melanocytes in the hair follicles and epidermis, leading to white patches on the skin and mucous membranes. Alopecia areata (AA) is a common immune-mediated condition in which autoimmune attack on hair follicles cause non-scarring hair loss. Both diseases significantly impact patients's physical and mental health.

Baricitinib Provides Significant Improvements in Quality of Life and Functioning in Adults with Moderate-to-Severe Atopic Dermatitis with Baseline Body Surface Area ≤ 40% and Severe Itch.

Introduction: Patients with moderate-to-severe atopic dermatitis (AD), a body surface area (BSA) of ≤ 40%, and an itch numerical rating scale (NRS) score of ≥ 7 ("BARI itch dominant") have been characterized as an important group to consider for the oral janus kinase (JAK) 1/2 inhibitor baricitinib (BARI). Herein we aim to evaluate quality of life (QoL) and functioning outcomes in adult patients with BSA ≤ 40% and itch NRS ≥ 7 at baseline (BL) who received BARI 4 mg in the topical corticosteroid (TCS) combination trial BREEZE-AD7.
Materials: BREEZE-AD7 was a randomized, double-blind, placebo-controlled, parallel-group outpatient study involving adult patients with moderate-to-severe AD who received once-daily placebo or 2-mg or 4-mg BARI in combination with TCS for 16 weeks.

Background: Intralesional (IL) steroids are the first-line treatment option for localized alopecia areata (AA). The present study aimed to compare the efficacy of topical calcipotriol with IL triamcinolone acetonide versus IL triamcinolone acetonide alone in AA.
Methods: This randomized single-blinded clinical trial was conducted in a dermatology outpatient department.
