Benzoyl peroxide (BPO) has been used extensively in industry and health care for more than a century and has been approved for the treatment of acne for over 60 years. Recently, BPO received a second approved indication by the US Food and Drug Administration (FDA) for the treatment of rosacea. Topical BPO use has historically been limited by tolerability, photosensitivity, oxidation, and, uncommonly, contact allergy. Research has led to enhanced efficacy and tolerability, as well as the combination of BPO with other topical medications. These advances have allowed extended use of BPO in additional dermatologic conditions that may not have been feasible in the past. Additionally, the role of BPO in preventing antibiotic resistance cannot be underestimated. Here, we discuss the historical limitations of BPO and recent advances developed to overcome these limitations. We also describe newly approved BPO medications and their role in aiding antibiotic stewardship. J Drugs Dermatol. 2023;22(1):54-59. doi:10.36849/JDD.7150.

A hybrid coating made of poly (methyl methacrylate) with SiO2-TiO2 particles (PMMA/SiO2-TiO2) has been developed for use as a coating on nanosatellites, evaluating its resistance to high vacuum by quantifying its weight loss. The coating was applied on an Al 7075 aluminum substrate used for the aerospace sector. PMMA/SiO2-TiO2 hybrid coatings were prepared using sol-gel reaction in situ assisted with sonochemistry.

In a quest to innovate biologically active molecules, the benzoylation of 4,6-dimethylpyrimidine-2-thiol hydrochloride (1) with benzoyl chloride derivatives was employed to produce a series of pyrimidine benzothioate derivatives (2-5). Subsequent sulfoxidation of these derivatives (2-5) using hydrogen peroxide and glacial acetic acid yielded a diverse array of pyrimidine sulfonyl methanone derivatives (6-9). In parallel, the sulfoxidation of pyrimidine sulfonothioates (10-12) yielded sulfonyl sulfonyl pyrimidines (13-15), originating from the condensation of compound 1 with sulfonyl chloride derivatives.

Combination topical treatments that target multiple acne pathophysiological pathways are more efficacious than topical monotherapies, and simplifying combination treatment by delivering multiple active ingredients as fixed combinations may improve adherence.
Methods: This review provides an overview of efficacy with 4 weeks of treatment in pivotal trials of fixed-combination topical treatments for acne.

The rotator cuff, a vital group of tendons and muscles in the shoulder, is essential for stabilizing the joint and enabling a wide range of arm movements. Rotator cuff tears, common across all age groups, often cause significant pain and functional limitations. Rotator cuff repair surgery aims to alleviate pain, restore function, and improve quality of life.

Polymer-based catalysts have garnered significant interest for their efficiency, reusability, and compatibility with various synthesis processes. In catalytic applications, polymers offer the advantage of structural versatility, enabling functional groups to be tailored for specific catalytic activities. In this study, we developed a novel magnetic copolymer of methyl methacrylate and maleic anhydride (PMMAn), synthesized via in situ chemical polymerization of methyl methacrylate onto maleic anhydride, using benzoyl peroxide as a free-radical initiator.
