METHODS: A total of 36 subjects (94.5% Fitzpatick Type IV-V) were recruited in this randomized double-blinded, split-face, controlled trial. Each side of the face was randomly assigned for treatment with either JS or SA. Subjects were treated once fortnightly for a total of three sessions. Lesion counting, Michaelsson acne score (MAS), photographs, and postacne hyperpigmentation index (PAHPI) were used to objectively assess the improvement. Complications were assessed during each visit. Statistical analysis was conducted using SPSS v22.0. Significance was set at P = 0.05.
RESULTS: At the end of therapy, significant reduction in inflammatory, noninflammatory lesions, MAS, and PAHPI scores (P
METHOD: A literature search for acne CPGs published between January 2008 and September 2013 was conducted. Two reviewers independently applied the Appraisal of Guidelines for Research and Evaluation (AGREE II) instrument. METHODological quality was evaluated by ranking in AGREE II domains and the highest number of items scoring above the neutral threshold score.
RESULTS: Four CPGs fulfilled the selection criteria, and the highest ranked were the European and Malaysian. Highest scores achieved by the former were for scope/purpose, stakeholder involvement, and rigor of development and by the latter were for scope/purpose, clarity of presentation, and applicability. Applicability was the lowest scoring of all domains for all CPGs.
CONCLUSION: European and Malaysian acne CPGs were ranked highest for methodological quality and may serve to inform clinical practice and guideline adaptation.
