Comparative efficacy and safety of the novel Picosecond Alexandrite Laser and the traditional combined Q-switched and long-pulse Nd: YAG lasers in melasma treatment: a randomized evaluator-blinded trial.

Melasma significantly impacts life quality, and while various laser therapies show promise, rigorous comparative studies, especially between the novel Picosecond Alexandrite Laser (PSAL) and the traditional combined modality of Q-switched and Long-pulse Nd: YAG Lasers (QLNYL), are notably lacking. This study aims to fill this gap by evaluating the efficacy and safety of these modalities, providing insights into their comparative advantages for clinical practice. In a prospective, evaluator-blinded study, 40 participants with Fitzpatrick Skin Types (FST) III and IV underwent three treatment sessions at four-week intervals with either PSAL or QLNYL.

A Comprehensive Analysis of Immunoglobulin E Levels, Allergen-Specific Sensitivities, and Clinical Manifestations in Allergic Dermatological Conditions: A Multicenter Retrospective Study in China.

Objective: To assess the correlations between Immunoglobulin E (IgE) levels, pruritus, and lesion severity in patients with eczema, atopic dermatitis, or urticaria.

Methods: A retrospective study was conducted and data of 814 patients who visited the dermatology or allergy clinics of multiple hospitals, from December 2019 to December 2021, were collected. Patients were divided into children group (<18 years, 325 cases), adult group (18-60 years, 435 cases), and older population group (>60 years, 54 cases) based on the age.

Systemic review and meta-analysis of the association between interleukin-10 and Takayasu arteritis.

Objective: The aim of this meta-analysis is to investigate the relationship between interleukin (IL)-10 levels and its polymorphism and Takayasu arteritis (TAK).

Methods: Five databases including PubMed, Web of Science, Ovid, Sinomed and China National Knowledge Infrastructure (CNKI) were gone through from inception to March 31, 2022. Studies were screened according to the inclusion and exclusion criteria.

Comparison of the efficacy and safety of picosecond Nd:YAG laser (1,064 nm), picosecond alexandrite laser (755 nm) and 2% hydroquinone cream in the treatment of melasma: A randomized, controlled, assessor-blinded trial.

Background: Increasing numbers of studies demonstrated that picosecond lasers (Picos) were effective and safe for melasma. However, A limited number of randomized controlled trials (RCTs) regarding Picos contribute to a modest level of evidence. Topical hydroquinone (HQ) remains to be the first-line therapy.

Association of TLR2 and TLR9 gene polymorphisms with atopic dermatitis: a systematic review and meta-analysis with trial sequential analysis.

Atopic dermatitis (AD) is a chronic, inflammatory skin disease. The mechanism was complex. Genetic mutations of Toll-like receptor (TLR) may be associated with AD, yet still unclear.

The changes of IgE levels in type 2 inflammatory diseases after treatment of dupilumab: a systematic review and meta-analysis.

Background: Dupilumab is approved for multiple type 2 inflammatory diseases. In the treatment procedure, the changes of IgE levels need further analysis. We evaluated the changes of IgE levels through meta-analysis, aiming to provide a more comprehensive result.

The relationship between vitamin D receptor gene polymorphisms and ankylosing spondylitis: a systematic review, meta-analysis and trial sequential analysis.

The relation between vitamin D receptor (VDR) gene polymorphisms and ankylosing spondylitis (AS) remains unclear. A systematic review and meta-analysis were conducted using six databases, including PubMed, Web of Science, EMBASE, CNKI, Wanfang and Cochrane Library. The selection of each study was based on inclusion and exclusion criteria.
