Digital Cholangioscopy-guided Cold Snare Resection of an Inflammatory Intraductal Pseudopolyp.

Dig Endosc 2021 Apr 12. Epub 2021 Apr 12.

Department of Gastroenterology and Hepatology, University Hospitals Leuven, Belgium.

Digital single-operator cholangioscopy (DSOC) has revolutionized the endoscopic diagnosis and treatment of various hepato-pancreaticobiliary diseases, such as indeterminate biliary strictures and large balloon dilation-refractory common bile duct (CBD) stones, using either a retrograde or antegrade approach. Direct visualization provided by DSOC has furthermore paved the road towards minimally invasive treatment of intraductal neoplasms, although little evidence is available in this specific context. A 70-year-old patient was admitted following several episodes of colicky abdominal discomfort, mixed liver function abnormalities and non-intentional weight loss. Read More

Background: Primary hyperoxaluria type 1 (PH1) is a rare genetic disease caused by hepatic overproduction of oxalate that leads to kidney stones, nephrocalcinosis, kidney failure, and systemic oxalosis. Lumasiran, an investigational RNA interference (RNAi) therapeutic agent, reduces hepatic oxalate production by targeting glycolate oxidase.

Methods: In this double-blind, phase 3 trial, we randomly assigned (in a 2:1 ratio) patients with PH1 who were 6 years of age or older to receive subcutaneous lumasiran or placebo for 6 months (with doses given at baseline and at months 1, 2, 3, and 6). Read More

CT as a Diagnostic Tool for Emphysematous Pyelitis: A Case Report.

Cureus 2021 Feb 23;13(2):e13513. Epub 2021 Feb 23.

Radiology, Dr. Ajmera Diagnostic, New Delhi, IND.

Gas forming infections of the renal collecting system occurs because of organisms like Escherichia coli, Klebsiella, and Proteus. If the gas is restricted to the collecting system, without causing involvement of the cortex, it is called emphysematous pyelitis; whereas, invasion and penetration of the cortex imply a more gruesome diagnosis of emphysematous pyelonephritis. A 59-year-old male patient, previously diagnosed with a large right renal calculus and having multiple co-morbidities presented to the surgery department with right flank pain; Double J (DJ) stenting was done to relieve the pain from colic due to obstructive renal calculi; the patient subsequently discharged without any post-procedural complications.
