Three-step irradiance schedule versus two-step irradiance schedule for pain control during topical 5-aminolevulinic acid-photodynamic therapy of facial acne in Chinese patients: A prospective randomized comparative study.

Background: A two-step irradiance schedule has been found to be useful for pain control during photodynamic therapy (PDT) on nonmelanotic skin cancer and condyloma acuminatum.

Objectives: To evaluate the efficacy of a new three-step irradiance schedule derived from the psychological "peak-end rule" and two-step irradiance schedule in relieving pain during 5-aminolevulinic acid PDT (ALA-PDT) on acne.

Methods: A total of 90 moderate to severe acne patients were enrolled in our study and randomly divided into two groups with a ratio of 1:1.

The assessment of psychology, quality of life in acne patients and evaluation of ALA-PDT for moderate to severe acne.

Objective: To evaluate the state of psychology and quality of life of patients effected by acne and also the efficacy and safety of photodynamic therapy with topical 5-aminolevulinic acid (ALA-PDT) for moderate to severe acne patients.

Methods: In the questionnaire part, a pre-designed form was filled out. The questionnaire was comprised of 2 sections related to acne including sociodemographic and disease information as well as Cardiff Acne Disability Index (CADI) and Self-Rating Anxiety Scale (SAS).

Relationship between IL-10 gene -819C/T polymorphism and the risk of inflammatory bowel disease: a meta-analysis.
