Drug-Induced Vanishing Bile Duct Syndrome: From Pathogenesis to Diagnosis and Therapeutics.

Semin Liver Dis 2021 Jun 15. Epub 2021 Jun 15.

Instituto de Fisiología Experimental (CONICET-UNR), Facultad de Ciencias Bioquímicas y Farmacéuticas, Universidad Nacional de Rosario, Rosario, Argentina.

The most concerned issue in the context of drug/herb-induced chronic cholestasis is vanishing bile duct syndrome. The progressive destruction of intrahepatic bile ducts leading to ductopenia is usually not dose dependent, and has a delayed onset that should be suspected when abnormal serum cholestasis enzyme levels persist despite drug withdrawal. Immune-mediated cholangiocyte injury, direct cholangiocyte damage by drugs or their metabolites once in bile, and sustained exposure to toxic bile salts when biliary epithelium protective defenses are impaired are the main mechanisms of cholangiolar damage.

Erysipelas is a bacterial soft tissue infection caused by β-haemolytic streptococci that spreads proximally along the lymphatic system of the skin. The entry sites of the pathogens can be minor injuries or chronic wounds. The diagnosis of erysipelas is made clinically by the spreading eythema and overheating of the skin, the reduced general condition with fever and chills as well as by means of serological inflammation parameters and must be distinguished from numerous differential diagnoses.

Direct 3D ultrasound fusion for transesophageal echocardiography.

Comput Biol Med 2021 May 21;134:104502. Epub 2021 May 21.

Division of Cardiology, Department of Medicine and Therapeutics, Prince of Wales Hospital and Laboratory of Cardiac Imaging and 3D Printing, Li Ka Shing Institute of Health Science, Faculty of Medicine, The Chinese University of Hong Kong, Hong Kong, China.

Background: Real-time three-dimensional transesophageal echocardiography (3D TEE) has been increasingly used in clinic for fast 3D analysis of cardiac anatomy and function. However, 3D TEE still suffers from the limited field of view (FoV). It is challenging to adopt conventional multi-view fusion methods to 3D TEE images because feature-based registration methods tend to fail in the ultrasound scenario, and conventional intensity-based methods have poor convergence properties and require an iterative coarse-to-fine strategy.
