RESUMO

Objective:To explore the efficacy and safety of microneedle radiofrequency combined with supramolecular salicylic acid in improving facial photoaging.Methods:Thirty patients treated for facial photoaging were randomly divided into the combined treatment group and the microneedle radiofrequency group. All patients were female, aged between 30 and 50 years, with an average age of (39.4±4.1) years. The combined treatment group was treated with microneedle radiofrequency combined with supramolecular salicylic acid, and the Microneedle radiofrequency group was treated with microneedle radiofrequency alone. The patients were followed up 3 days, 7 days, 14 days, 28 days and 3 months after treatment. The results of VISIA, skin physiology and patients' satisfaction were used to compare the two groups of patients after treatment.Results:After 3 months of treatment, the skin pores (11.98±2.14 vs. 15.54±1.52), brown spots (12.40±1.85 vs. 15.84±1.42), ultraviolet spots (6.74±0.87 vs. 11.20±1.70), skin physiological status (transepidermal water loss): 11.84±1.80 vs 13.09±1.96 g/(h·m) 2, stratum corneum water content: 84.91±2.86 % vs 80.29±3.58 %, melanin index: 110.07±15.02 vs. 122.30±9.97, erythema index: 220.43±19.69 vs. 236.30±16.55), elasticity (75.98±3.94 vs. 69.89±3.58), epidermal thickness (1401.33±178.43 vs. 1217.13±139.77), skin color improvement (effective rate 86.7% vs. 40.0%) and patients' satisfaction (total satisfaction was 93.3% vs 67.0%) in the combined treatment group were significantly superior than those in the microneedle radiofrequency group, and the differences were statistically significant ( P<0.05). The reaction of moderate and severe erythema (the incidence rate 40.0% vs. 86.7%) and edema (the incidence rate 26.7% vs. 80.0%) in the combined treatment group was also significantly lower than that in the microneedle radiofrequency group ( P<0.05). No adverse pigmentation was reported in both groups after treatment. Conclusions:The combination of microneedle radiofrequency and supramolecular salicylic acid in the treatment of facial photoaging has definite clinical effect and high safety, which is worthy of clinical application.

RESUMO

This review comprehensively summarizes clinical assessment tools which have been developed and validated for cholinergic urticaria (CholU) , involving diagnosis and severity assessment of CholU, assessment of patients′ quality of life, and assessment of disease control. The application methods and status of relevant tools in clinical practice are introduced in detail.

RESUMO

A large number of studies have shown that immunoglobulin E (IgE) not only participates in the occurrence and development of allergic reactions, but also induces and aggravates autoimmune reactions through various mechanisms. IgE autoantibodies have been confirmed to be present in a variety of autoimmune skin diseases, and may be involved in the occurrence and development of related diseases by affecting multiple immune cells such as dendritic cells, mast cells, and basophils via binding to autoantigens. This review summarizes the role and possible mechanism of action of IgE in the induction and exacerbation of autoimmune skin diseases such as systemic lupus erythematosus, bullous pemphigoid and chronic idiopathic urticaria, and provides a theoretical basis for clinical diagnosis and treatment.
