[Urinary stone imaging tests.]

Arch Esp Urol 2021 Jan;74(1):24-34

Servicio de Urología. Hospital Universitario 12 de Octubre. Madrid. España.

Imaging in urolithiasis has a wide group of techniques, with different characteristics, limitations, and indications, which together allow the management of this prevalent pathology. Plain abdominal radiography and ultrasound are very accessible and in expensive techniques that combined present an acceptable sensitivity and specificity. They are widely used for monitoring the evolution of stone disease and for evaluation after treatments (surgery or SWL). Read More

Familial disease history and fur color type are associated with urinary tract disease in farmed mink (Neovison vison).

Res Vet Sci 2020 Dec 1;133:326-331. Epub 2020 Nov 1.

Department of Veterinary and Animal Sciences, Faculty of Health and Medical Sciences, University of Copenhagen, Ridebanevej 3, 1870 Frederiksberg C, Denmark.

Mink urinary tract disease (MUTD) and mink fatty liver disease (MFLD) constitute two important disease entities in the mink production associated with sudden mortality and economic loss. Genetic factors or heritability of the diseases have not previously been investigated. Since mortality associated with MUTD and MFLD mainly occurs in the young immature mink, a potential genetic predisposition would rarely be passed on by the mink itself but potentially by relatives.

Point-of-Care Ultrasonography.

Am Fam Physician 2020 03;101(5):275-285

Naval Hospital Jacksonville, Jacksonville, FL, USA.

Point-of-care ultrasonography (POCUS) is performed by a physician at the bedside and is standard practice in obstetric, emergency, and musculoskeletal medicine. When compared with formal sonography, POCUS is equivalent in screening for abdominal aortic aneurysm and as accurate in diagnosing deep venous thrombosis. POCUS has high accuracy for diagnosing pneumonia and detecting acute decompensated heart failure but is less accurate than computed tomography for identifying pulmonary embolism. Read More
