A retrospective analysis of distinguishing features of chest HRCT and clinical manifestation in primary Sjögren's syndrome-related interstitial lung disease in a Chinese population.
To characterize the distinctive chest high-resolution computerized tomography (HRCT) features and clinical manifestations of primary Sjögren syndrome (pSS)-related interstitial lung disease (ILD). The demographic data, clinical manifestations, and laboratory and radiological findings of 527 pSS patients were retrospectively analyzed. ILD was defined based on the presences of pulmonary signs in HRCT. ⋯ ILD is the common pulmonary involvement of pSS and the prevalence of pSS-ILD is 39.1%. The single pattern of NSIP and UIP in HRCT are the commonest, and about 40% of the pSS-ILD patients possess multiple patterns in HRCT. The classification of idiopathic pulmonary fibrosis cannot completely include the pulmonary imaging features of pSS-ILD.

Multicenter StudyValidity of the central sensitization inventory with measures of sensitization in people with knee osteoarthritis.
Our purpose was to determine the validity of the Central Sensitization Inventory (CSI) with psychophysical tests, psychological and physical factors in patients with Knee Osteoarthritis (KOA). Patients with KOA were recruited from three Montreal hospitals. Psychophysical tests (pressure pain threshold, conditioned pain modulation, temporal summation) were conducted and questionnaires administered to determine the presence of neuropathic pain, somatization, anxiodepressive symptoms, pain catastrophizing (PC), and widespread pain (WSP). ⋯ After adjustment for covariates, a multivariable linear regression determined WSP (unstandardized ß 4.161(0.067, 8.255) p = 0.046), somatization (unstandardized ß 1.828 (1.368, 2.288) p < 0.005), and anxiodepressive symptoms (unstandardized ß 0.419 (0.107, 0.730) p = 0.009) significantly predicted CSI scores. The CSI is more strongly associated with psychological factors than psychophysical test results in a KOA population. Its moderate sensitivity and specificity suggest it should be used as part of a more comprehensive evaluative toolkit.

An epidemiological study of the prevalence rate of inflammatory back pain and axial spondyloarthritis in a university in the south of China.
Inflammatory back pain (IBP) is an important clinical feature for axial spondyloarthritis (SpA). Yet, little is known about their prevalences in China. We conducted an epidemiological study in a university to detect the prevalences of IBP and axial SpA according to the Assessment of SpondyloArthritis International Society (ASAS) criteria. ⋯ For axial SpA, female/male was 4/9(P = 0.014). In southern China, the prevalences of CLBP and IBP were respectively 19.39 and 2.94% in university, and the prevalence of axial SpA was 0.34%. Although more female students had CLBP, males were more likely to suffer from axial SpA.
