BACKGROUND: Keloid, a fibroproliferative skin disorder, requires accurate scar assessment. Comprehensive evaluation using a standardized instrument from both patient and observer perspectives is essential to capture its multidimensional impact. This study aimed to translate, culturally adapt, and validate the generic patient and observer scar assessment scale (POSAS) 3.0 into Indonesian for keloid assessment. METHODS: A cross-sectional design was adopted following the translation and cultural adaptation guidelines. The instrument was translated into Indonesian by certified translators and administered to 68 keloid patients and 62 dermatologists especially recruited from Pekanbaru and the surrounding areas. Content validity was assessed using the scale-level content validity index average (S-CVI/Ave), construct validity through exploratory factor analysis (EFA), internal consistency with Cronbach’s alpha, test-retest reliability using the intraclass correlation coefficient (ICC), and external validity by correlating the observer scar assessment scale (OSAS) with the modified Vancouver scar scale (mVSS). RESULTS : The Indonesian version of the generic POSAS 3.0 demonstrated strong psychometric properties. The S-CVI/Ave was 0.97. The EFA revealed 3 factors for the patient scar assessment scale and two for the OSAS, explaining 71.25% and 73.1% of the variance, respectively. Cronbach’s alpha was 0.79–0.90 and ICC was ≥0.83. External validity was confirmed by a strong correlation with the mVSS (Spearman’s rho = 0.82, p<0.001). CONCLUSIONS The Indonesian adaptation of the POSAS 3.0 is a valid and reliable tool for comprehensive keloid scar assessment. Future research should explore the responsiveness to therapeutic interventions.

BACKGROUND: Atopic dermatitis (AD) is a common skin condition among Asians. Recent studies have shown that Asian AD has a unique clinical and immunologic phenotype compared with European/American AD. OBJECTIVE: The Asian Academy of Dermatology and Venereology Expert Panel on Atopic Dermatitis developed this reference guide to provide a holistic and evidence-based approach in managing AD among Asians. METHODS: Electronic searches were performed to retrieve relevant systematic reviews and guidelines on AD. Recommendations were appraised for level of evidence and strength of recommendation based on the U.K. National Institute for Health and Care Excellence and Scottish Intercollegiate Guidelines Network guidelines. These practice points were based on the consensus recommendations discussed during the Asia Pacific Meeting of Experts in Dermatology held in Bali, Indonesia in October 2016 and April 2017. RESULTS: The Expert Panel recommends an approach to treatment based on disease severity. The use of moisturizers is recommended across all levels of AD severity, while topical steroids are recommended only for flares not controlled by conventional skin care and moisturizers. Causes of waning efficacy must be explored before using topical corticosteroids of higher potency. Topical calcineurin inhibitors are recommended for patients who have become recalcitrant to steroid, in chronic uninterrupted use, and when there is steroid atrophy, or when there is a need to treat sensitive areas and pediatric patients. Systemic steroids have a limited role in AD treatment and should be avoided if possible. Educational programs that allow a patient-centered approach in AD management are recommended as an adjunct to conventional therapies. Recommendations on the use of phototherapy, systemic drugs, and emerging treatments are also included. CONCLUSION: The management of AD among Asians requires a holistic approach, integrating evidence-based treatments while considering accessibility and cultural acceptability.
