Renal ultrasound findings secondary to COVID-19 related collapsing focal segmental glomerulosclerosis - A case report.

SARS-CoV-2 (COVID-19) is well known to have extrapulmonary manifestations, including acute renal failure. While radiologic findings of COVID-19 pulmonary-involvement have been described, renal findings associated with COVID-19 have not. We present a case of a 38-year-old Afro-Caribbean female diagnosed with COVID-19 whose renal ultrasound showed increased parenchymal echogenicity, decreased global color Doppler signal with elevated resistive indices, but no large vessel thrombi. Non-targeted renal biopsy demonstrated collapsing focal segmental glomerulosclerosis (FSGS), likely secondary to COVID-19 infection, which may be a specific manifestation of this disease that has been predominantly reported in Black patients. We report several findings on renal ultrasound with duplex Doppler not previously associated with COVID, specifically with FSGS, which in conjunction can be useful to both the radiologist and the clinician, potentially pointing them in the direction of this diagnosis and early treatment.

The Effect of Immediate Versus Delayed Port Access on 30-Day Infection Rate.

This study compared the 30-day infection risk of chest ports accessed on the same day as placement and chest ports with delayed initial access. The aim was to evaluate a larger data set that provided evidence for the development of port access guidelines. A retrospective chart review of 3322 chest port placement procedures performed between October 15, 2003, and June 10, 2015, was conducted at the interventional radiology department of a single institution. Procedure notes and health records were reviewed to determine time of initial port access, evidence of infection within a 30-day window of port placement, and causal organism(s) of infection. The results demonstrated that 64 ports (1.93%) met infection criteria within 30 days of placement, including 30 of the 945 ports immediately accessed and 34 of the 2377 ports not immediately accessed (3.17% vs 1.43%; P < .005). Dual lumen devices had a statistically significant higher rate of infection compared with single lumen devices (P = .006). This study concluded that there is a statistically significant higher rate of infection if a port is accessed immediately versus when access is deferred to later than 24 hours after placement.
