The effect of intravitreal recombinant tissue plasminogen activator injection on diabetic tractional fibrovascular membranes: Proposed criteria using optical coherence tomography.

Purpose: To evaluate the effect of intravitreal recombinant tissue plasminogen activator (tPA) on diabetic tractional fibrovascular membranes (FVM) using proposed optical coherence tomography (OCT) criteria.

Methods: This prospective, interventional case series enrolled eyes with tractional retinal detachment who were candidates for pars plana vitrectomy. OCT images were obtained to evaluate the border of the attached-detached retina and overlying FVP at baseline and 1 week post-intravitreal tPA injection using the follow-up scan acquisition protocol.

Molecular detection of Candida spp. and Aspergillus fumigatus in bronchoalveolar lavage fluid of patients with ventilator-associated pneumonia.

Background: Ventilator-associated pneumonia (VAP) is a common nosocomial infection in critically ill patients with high morbidity and mortality rates. The etiology of VAP is usually bacterial. Opportunistic fungi such as Candida and Aspergillus species (spp.
