Indwelling time of peripherally inserted central catheters and incidence of bloodstream infections in haematology patients: a cohort study.

Background: We aimed to assess whether longer indwelling time of peripherally inserted central catheters (PICC) increases risk of central line associated bloodstream infections (CLABSI) in haematology patients.

Methods: Multicentre retrospective cohort study among haematology patients receiving PICCs between 2013 and 2015. Occurrence of CLABSI based on CDC definitions was assessed.

Bilateral optic neuritis with branch retinal artery occlusion associated with vaccination.

A case of a 40-year old marine with bilateral optic neuritis and a branch retinal artery occlusion after vaccination is presented. Blood investigations showed no abnormalities. Cerebrospinal fluid studies revealed a lymphocytic pleocytosis and IgG antibodies against hepatitis A and rabies.

Visual acuity, spectacle blur and slit-lamp biomicroscopy on asymptomatic contact-lens-wearing recruits.

Refraction data of 644 Dutch Army and Air Force recruits wearing contact lenses or spectacles were statistically compiled and correlated with the type of lenses worn. Visual acuity with contact lenses was far from optimal because the power of the lenses was incorrect or the optical quality poor. This applied particularly to soft contact lenses.
