Interaction Effect of Psoriasis and Cancer on the Risk of All-Cause Mortality: A Prospective Cohort Study of NHANES Data.

Background: The relationship between psoriasis, cancer, and mortality has been reported in observational studies. Considering the high heterogeneity in systematic review and meta-analysis and inconsistent results in previous studies, the association between psoriasis, cancer, and mortality warrants more investigation. The primary objective of this study was to explore the joint impact of psoriasis and cancer on mortality in a representative cohort of adults residing in the United States.

The role of epidermal growth factor-containing topical products on recovery and post-inflammatory hyperpigmentation prevention after laser surgeries: A systematic review and meta-analysis.

Background: Post-inflammatory hyperpigmentation (PIH) is a common complication after laser surgeries. Recent studies applied epidermal growth factor (EGF) on the lasered area after laser surgery to decrease the incidence of PIH with controversial results. Therefore, a comprehensive literature review of randomized controlled trials (RCTs) was conducted to investigate the issue.

Evaluating the quality of life among melasma patients using the MELASQoL scale: A systematic review and meta-analysis.

Background: According to the literature, pigmentary disorders have a significantly negative impact on a person's health-related quality of life. Moreover, among pigmentary disorders, incidence of melasma ranks high. The Melasma Area and Severity Index (MASI) is the scale that is generally used to evaluate a melasma-affected area and its severity.

Efficacy and safety of pulsed dye laser for the treatment of surgical scars: a systematic review and meta-analysis.

Various clinical trials have explored whether the pulsed dye laser (PDL) method is safe to treat scars, especially surgical scars. However, comprehensive evidence confirming the exact outcomes of PDL for treating surgical scars is lacking. The efficacy and safety of PDL in the treatment of surgical scars were determined through a review of several studies.

Risk of metabolic syndrome in patients with lichen planus: A systematic review and meta-analysis.

Background: Studies have investigated whether patients with lichen planus are at a high risk of metabolic syndrome; however, currently, no conclusive data are available in this regard.

Objective: This meta-analysis was performed to analyze the published literature investigating the association between metabolic syndrome and lichen planus.

Method: Two reviewers independently searched 4 databases (PubMed, Embase, the Cochrane Library and Web of Science) for observational studies assessing the prevalence of metabolic syndrome in patients with lichen planus.
