The impact of COVID-19 in hemodialysis patients: Experience in a hospital dialysis unit.

Introduction: COVID-19 is a very high transmission disease with a variable prognosis in the general population. Patients in hemodialysis therapy are particularly vulnerable to developing an infectious disease, but the incidence and prognosis of hemodialysis patients with COVID-19 is still unclear. The main objective is to describe the experience of our dialysis unit in preventing and controlling the spread of SARS-CoV-2 infection.

Comparison of packing material in an animal model of middle ear trauma.

Purpose: To compare the performance of absorbable gelatin sponge (AGS) with polyurethane foam (PUF) as middle ear packing material after mucosal trauma.

Materials And Methods: Using a randomized, controlled and blinded study design fifteen guinea pigs underwent middle ear surgery with mucosal trauma performed on both ears. One ear was packed with either PUF or AGS while the contralateral ear remained untreated and used as non-packed paired controls.
