The purpose of this study was to evaluate the potential of magnetic resonance imaging (MRI) in vivo for the characterization of tissue changes associated with acute myocardial rejection after cardiac transplantation. Of 15 dogs that underwent heterotopic cardiac transplantation, six served as untreated controls, and nine received immunosuppressive therapy (25 mg/kg/day cyclosporine, 1 mg/kg/day...

Low concordance in grading atypical (dysplastic) melanocytic nevi (AMN) has been reported, and no systematic evaluation is available. We studied 123 AMN with architectural and cytologic atypia (40 associated with atypical-mole syndrome), classified according to standard criteria by 3 independent observers. Histologic variables included junctional and dermal symmetry, lateral extension, cohesion...

OBJECTIVE To compare the efficacy of dapsone, diphenhydramine, colchicine, and intralesional triamcinolone in the treatment of brown spider bites. We used a purified venom that reproducibly produces a large eschar. To mimic real-life circumstances, all agents were administered following a 2-hour delay after envenomation. The animals were evaluated for the presence of coagulopathy to determine i...

Classification of primary CNS tumours is currently achieved by complementing histologic analysis with molecular information, in accordance the WHO guidelines, and aims at providing accurate prognosis optimal patient management. cIMPACT-NOW update 3 now recommends grading diffuse IDH-wild type astrocytomas as grade IV glioblastomas if they bear one or more following alterations: EGFR amplificati...

Objective: To investigate the risk factors of developing intravesical recurrence (IVR) in patients with upper urinary tract urothelial carcinoma (UTUC) who underwent ureterorenoscopy (URS) before radical nephroureterectomy bladder cuff excision (RNU).
 Materials and Methods: This retrospective study collected data from medical records diagnosed UTUC between January 2012 December 2019. All ...
