Poisoning by high concentrations of dioxin and its related compounds manifests variable toxic symptoms such as general malaise, chloracne, hyperpigmentation, sputum and cough, paresthesia or numbness of the extremities, hypertriglyceridemia, perinatal abnormalities, and elevated risks of cancer-related mortality. Such health hazards are observed in patients with Yusho (oil disease in Japanese) who had consumed rice bran oil highly contaminated with 2,3,4,7,8-pentachlorodibenzofuran, polychlorinated biphenyls, and polychlorinated quaterphenyls in 1968. The blood concentrations of these congeners in patients with Yusho remain extremely elevated 50 years after onset. Dioxins exert their toxicity via aryl hydrocarbon receptor (AHR) through the generation of reactive oxygen species (ROS). In this review article, we discuss the pathogenic implication of AHR in dioxin-induced health hazards. We also mention the potential therapeutic use of herbal drugs targeting AHR and ROS in patients with Yusho.

Tapinarof is a nonsteroidal, topical, aryl hydrocarbon receptor agonist approved for the treatment of atopic dermatitis (AD) in Japanese patients aged ≥12 years. We evaluated the efficacy and safety of tapinarof in Japanese pediatric patients aged 2 to 11 years with AD in a phase 2, multicenter, randomized, double-blind, vehicle-controlled trial. Eligible patients (N = 121) were randomized 1:1:1 to receive tapinarof cream 0.

Article Synopsis
- - Tapinarof cream (1%) was tested for treating plaque psoriasis in two phase 3 trials involving Japanese patients, showing a significant improvement in psoriasis symptoms compared to a vehicle (inactive treatment).
- - In the first trial (ZBA4-1), 20.06% of patients using tapinarof achieved high success at week 12 compared to only 2.5% with the vehicle, while in the second trial (ZBA4-2), the treatment success rate increased to 56.3% by week 52.
- - The treatment was generally safe, with most side effects being mild or moderate, such as folliculitis and contact dermatitis, confirming tapinarof cream's efficacy and safety for

Background: Oral pigmentation is due to the accumulation of one or more pigments in tissues, causing changes in the color of the oral mucosal surfaces. Understanding the exact global prevalence of oral pigmentation and its associated factors helps researchers make the proper interventions at the right time; in this respect, the objective of the present systematic review and meta-analysis was to determine the global prevalence of oral pigmentation and its related factors.
Method: A systematic review and meta- analysis were conducted using the following databases: Magiran, SID, Scopus, Embase, PubMed, Web of Science (WoS), and Google Scholar.
