From Nature to Healing: Development and Evaluation of Topical Cream Loaded with Pine Tar for Cutaneous Wound Repair. Pharmaceutics 2024; 16:859.

Abstract
Despite the numerous efforts to find an appropriate therapeutic modality, diabetic wounds remain a global unsolved problem. Therefore, our study aimed to develop a topical formulation loaded with pine tar and to investigate its wound-healing capacity. After phytochemical profiling of pine tar, an oil-in-water emulsion with 1% pine tar was prepared. The physical, chemical, and microbiological stability of prepared pine tar cream (PTC) was assessed during six months. Additionally, safety potential was examined in healthy rats, while wound-healing potential was accessed by creating excision wounds in diabetic rats. Diabetic animals were divided into four groups: untreated or topically treated with either the cream base, PTC, or silver sulfadiazine cream. Wound healing was monitored at the following time points (0, 7, 14, and 21 days) through macroscopic, biochemical, and histological examinations. Our PTC formula showed good physicochemical properties and remained stable and compatible for cutaneous application. PTC showed a remarkable increase in wound closure rate and led to attenuation of morphological alterations in skin samples. These findings were associated with significantly improved redox status and enhanced hydroxyproline levels in PTC relative to the untreated and cream base groups. Our results demonstrated that PTC might serve as a promising tool for the management of diabetic wounds.

Abstract
Allergic skin diseases are highly prevalent among children. Patients with allergic skin diseases experience sociopsychological and quality-of-life (QoL) burdens in excess of those in the general population. Children and their caregivers are especially vulnerable to the burden of many of the common allergic skin diseases. In the past few decades, researchers have developed a number of disease-specific scores and indices for the measurement of QoL for childhood skin diseases. Most of the research in this area has focused on atopic eczema and urticaria and less so on allergic contact dermatitis. We provide an overview of QoL and its assessment for these dermatologic conditions.

Abstract
Atopic dermatitis (AD) is a common inflammatory dermatosis that has multiple contributing factors including genetic, immunologic and environmental. Staphylococcus aureus (SA) has long been associated with exacerbation of AD. SA produces many virulence factors that interact with the human skin and immune system. These superantigens and toxins have been shown to contribute to adhesion, inflammation and skin barrier destruction. Recent advances in genome sequencing techniques have led to a broadened understanding of the multiple ways SA interacts with the cutaneous environment in AD hosts. For example, temporal shifts in the microbiome, specifically in clonal complexes of SA, have been identified during AD flares and remission. Herein, we review mechanisms of interaction between the cutaneous microbiome and SA and highlight known differences in SA clonal complexes that contribute to AD pathogenesis. Detailed knowledge of the genetic strains of SA and cutaneous dysbiosis is becoming increasingly relevant in paving the way for microbiome-modulating and precision therapies for AD.

Abstract
Introduction Eczema or atopic dermatitis (AD) is a chronically relapsing dermatosis characterized by pruritus and a significant impact on the quality of life. Methods The authors undertook a structured search of peer-reviewed research articles from PubMed and Google Scholar. Recent and up-to-date studies relevant to the topic were included. Results This report overviews current treatment and experimental drug for AD. Topical agents including topical phosphodiesterase E4 (PDE4) inhibitors such as crisaborole are efficacious in the treatment of AD with few side effects. Monoclonal antibodies such as dupilumab given subcutaneously are efficacious for more severe disease. Systemic treatment can ameliorate symptoms in severe and recalcitrant AD. New systemic treatment includes several traditional herbal formulations that have undergone clinical trials using modern research methodology to determine their efficacy and safety. AD is associated with many complicating psychosocial issues. Often suboptimal efficacy is due to unrealistic expectations and poor compliance making treatment difficult in spite of effective treatment and efforts in drug discovery. Randomized trials have shown that novel topical and subcutaneous medications are safe and efficacious. Regarding herbs, a methodology for the investigation of herbal medications is often flawed and scientific evidence is lacking. Experimental drugs include various biologics, PDE4 and JAK inhibitors in topical, oral, subcutaneous or intravenous forms are in various phases of trials. Conclusion Many novel medications demonstrate efficacy for AD. Experimental drugs include various biologics, PDE4 and JAK inhibitors are in various phases of trials.
