Enforcing the "4T": An In-Line Calculator for HIT Antibody Ordering in the Electronic Medical Record.

Heparin-induced thrombocytopenia (HIT) remains a difficult clinical diagnosis, even with the under-utilized standardized scoring systems, like the '4T' score, to aid in clinical decision-making. Our quality improvement study sought to assess the use of '4T' score, improve the use of HIT antibody (HITA) testing and improvement management of possible HIT by implementing an in-line calculator with guidance within our electronic medical record (EMR) at our institution. We retrospectively reviewed patient charts between October 2017 and October 2018, assessing practices before and after implementation of the '4T' in-line calculator in April 2018.

Outcomes of upper tract urothelial carcinoma with isolated lymph node involvement following surgical resection: implications for multi-modal management.

Background: There are limited data on the oncologic outcomes of upper tract urothelial carcinoma with isolated lymph node (LN) involvement (pN+ M0) following surgical resection. We examined pN+ M0 UTUC in a large, nationwide oncology dataset to characterize its natural history, describe trends in utilization of perioperative chemotherapy, and identify clinicopathologic features associated with survival.

Methods: We identified 794 patients aged 18-89 years who underwent radical nephroureterectomy with lymph node dissection for pN+ M0 UTUC from 2006 to 2013 in the National Cancer Database.

Cardiogenic shock from coronary vasculitis in granulomatosis with polyangiitis.

Granulomatosis with polyangiitis (GPA) is a systemic vasculitis characterised by necrotising inflammatory changes in small-sized and medium-sized vessels and granuloma formation. It most commonly involves the kidneys and respiratory tract, but it can present with widespread manifestations involving any organ system. Rarely, it causes coronary vasculitis which can precipitate a severe cardiomyopathy.
