Abstract
OBJECTIVE To help identify homogeneous subgroups among patients with anti-polymyositis-scleroderma-antibodies (PM-Scl-Abs) positive auto-immune diseases regardless of diagnostic classifications. METHODS This multicentric (four hospitals) retrospective study collected all consecutive patients (from 2011 to 2021) with positive testing for anti-PM-Scl-Abs in a context of connective tissue disease. Subgroups of patients with similar clinico-biological phenotypes were defined using unsupervised multiple correspondence analysis and hierarchical clustering analysis of the features recorded in the first year of follow-up. RESULTS One hundred and forty-two patients with anti-PM-Scl-Abs were evaluated and 129 patients were included in the clustering analysis and divided into 3 clusters. Cluster n°1 (n = 47) included patients with frequent skin thickening, digestive involvement and interstitial lung disease (ILD) with Non Specific Interstitial Pneumonia (NSIP). They were more likely to develop progressive fibrosing ILD. Cluster n°2 (n = 36) included patients who all featured NSIP with frequent Organizing pneumonia associated pattern and mechanic's hands. This subgroup had increased risk of relapse and ILD was characterized by a good functional outcome. Cluster n°3 (n = 46) was characterized by predominant or isolated musculoskeletal involvement and frequently matched undifferentiated connective tissue disease (UCTD) criteria. Although very frequent among Anti PM-Scl-Abs positive patients, muscle involvement was less discriminating compared with skin thickening and ILD pattern to classify patients into subgroups. CONCLUSION Anti-PM-Scl-Abs associated auto-immune diseases are segregated into 3 subgroups with distinct clinical phenotype and outcomes. Skin thickening and NSIP are determinant predictors in segregation of theses populations.

Abstract
INTRODUCTION Medical tourism is rapidly becoming a worldwide, multibillion-dollar industry. Iran has a high potential for this industry. The purpose of this study was to examine the medical tourism cluster, using Diamond Analysis tool. MATERIALS AND METHODS This study is a descriptive, analytical and qualitative one. Thirty professionals and researchers in this field were interviewed and official documents belonging to the Health ministry as well as tourism organization and finally related literature were examined. The data was analyzed using content analysis method. RESULTS Positive and negative parts of the medical tourism industry of Iran were determined according to diamond of advantage. CONCLUSION The strategic issues were identified and a number of possible solutions for addressing them were recommended. More and effective public-private participations, aggressive marketing, improving infrastructures, and international accreditation of health care facilities and human resources development could improve medical tourism industry in the country.
