Objective: To evaluate the application of contrast-enhanced ultrasonography (CEUS) in diagnosis of inflammatory pseudotumor of liver (IPL).
Methods: The contrast-enhanced untrasonography was performed in 32 cases of IPL and the results were retrospectively analyzed.
Result: Among total 32 cases, 21 had absent contrast enhancement (type I); 6 had rimlike or stringlike enhancement during arterial phase and presented hypoechoic lesions during the late phase (type II); 2 had diffuse and homogeneous enhancement during early arterial phase,persisting hyperechoic during the late phase (type III); 3 had enhancement during arterial phases and washed out more quickly than liver parenchymal (type IV).
Conclusion: The perfusion pattern of IPL with CEUS varies, the predominant type is no contrast enhancement; type IV may be confused with atypical hepatic carcinoma, in that case the needle biopsy is necessary.

Background And Aims: Inflammatory bowel disease (IBD) develops in genetically susceptible individuals exposed to certain environmental factors, of which only a few have been established. We aimed to assess whether bariatric surgery (BS) and severe obesity are associated with an increased risk of developing IBD.
Methods: Adults diagnosed with obesity or severe obesity between 2005 and 2020 were identified from the Catalan Health Surveillance System; those diagnosed with IBD prior to the diagnosis of obesity or severe obesity were excluded.

Introduction: Therapeutic drug monitoring (TDM) in inflammatory rheumatic diseases (RMDs) is gaining interest. However, there are unresolved questions about the best practices for implementing TDM effectively in clinical settings.
Objective: The primary objective of this study was to evaluate whether early TDM of adalimumab predicts drug survival at 52 weeks in patients with RMDs.

Morphea is a chronic inflammatory fibrosing disorder. Since fibrosis is the hallmark of both scars and morphea, our attention was raised for the possible use of Fractional Ablative CO lasers and microneedling as treatment modalities for morphea. To compare the efficacy and safety of Fractional Ablative CO lasers and microneedling in the treatment of morphea.
