Control of an outbreak of post-transplant cutaneous mucormycosis by removing the vehicle: An intervention study of contiguous cohorts.

Background: An outbreak of post-kidney transplant cutaneous mucormycosis (PK-CM), a severe and even fatal complication in immunocompromised patients, occurred in our institution. The objective of this study was to compare the usual fixation of sterile wound dressings with non-sterile elastic bandages and fixation with sterile bandages processed at our centralized sterile services department with regard to PK-CM prevention.

Methods: We conducted a before-and-after trial in a private tertiary care hospital.

[Septic arthritis byAggregatibacteraphrophilus: Case report].

Introduction: Septic arthritis by Aggregatibacter aphrophilus is an uncommon entity, so it's important to diagnose it early, to avoid serious consequences. In adults, the knee is the most affected site.

Methods: We present a case of a 17-year-old boy, with pain in the left knee since one month ago.

Control of an outbreak of postoperative bone mucormycosis: An intervention study of contiguous cohorts.

An outbreak of postoperative bone mucormycosis following arthroscopic anterior cruciate ligament reconstruction in a tertiary referral center in Paraná, Argentina, could have been transmitted through an arthroscopic anterior cruciate ligament reconstruction-exclusive contaminated item. The outbreak was controlled after changing from a system of direct delivery of implants and instruments to the operating room without proper verification, to a controlled and centralized process; specifically, the institution's pharmacy verified the quality and traceability of implants, and instruments were processed only by the institution's central sterile services department.

Estimating the likelihood of success with the initial empiric antimicrobial therapy in patients with nosocomial infections.

In order to estimate the likelihood of success (SL) with the initial empiric antimicrobial therapy, the following formula was constructed with data subjected to prior clinical validation in real time: SL (%) = (Nº isolates susceptible to IEAT/Nº patients with MDI) × 100. Where the numerator of the formula represents the total number of isolates recovered from the assessed type of infection, that was susceptible to any component of empiric antimicrobial therapy (IEAT) used, and the denominator represents the total number of patients with the same assessed, but microbiologically documented infection (MDI). For male hospital-acquired urinary tract infection, only imipenem reached a suitable SL value (i.
