OBJECTIVE To compare the refractive outcome of eyes treated with cryotherapy for threshold retinopathy of prematurity (ROP) with eyes treated with laser photocoagulation. DESIGN Extended follow-up of a randomized controlled clinical trial. PARTICIPANTS One hundred eighteen eyes from 66 patients were randomly assigned to receive either cryotherapy or(More)
OBJECTIVES To describe the characteristics of fundus fluorescein angiography in retinopathy of prematurity (ROP) and to explore the possible benefits of fundus fluorescein angiography over conventional indirect ophthalmoscopy in the screening for and management of ROP. PATIENTS AND METHODS Beginning in January 2003, 23 consecutive patients were recruited(More)
Competency based medical education involves assessing physicians-in-training in multiple roles. Training programs are challenged by the need to introduce appropriate yet feasible assessment methods. We therefore examined the utility of a structured oral examination (SOE) in the assessment of the 7 CanMEDS roles (Medical Expert, Communicator, Collaborator,(More)
BACKGROUND Peripheral intravenous (PIV) catheters are widely used in modern medical practice. However, mechanical or infectious complications often necessitate their removal and/or replacement. Heparin has been shown to be effective in prolonging the patency of peripheral arterial catheters and central venous catheters, but may result in life threatening(More)
BACKGROUND Benzodiazepines are being used in neonatal intensive care units for sedation and control of seizures. However, anecdotal reports suggest that their use in infants may be associated with serious adverse effects (AEs). OBJECTIVE To determine the incidence of AEs from benzodiazepine use in preterm and full-term infants. METHODS Retrospective(More)
PURPOSE To quantify the effect on refractive outcomes after cataract surgery of personalization of Haigis intraocular lens (IOL) constants for a given surgeon-IOL combination. SETTING Institute of Eye Surgery and Institute of Vision Research, Whitfield Clinic, Butlerstown North, Waterford, Ireland. METHODS Personalization of Haigis IOL constants was(More)
OBJECTIVE To assess visual and structural outcomes after laser photocoagulation and transscleral cryotherapy for threshold retinopathy of prematurity (ROP) after 10 years. DESIGN Extended follow-up of a randomized controlled clinical trial. PARTICIPANTS One hundred eighteen eyes from 66 patients were randomly assigned to receive either cryotherapy or(More)
The use of plain radiographs in assessing the correct position of peripherally inserted central catheter (PICC) line tips is not always accurate. Ultrasound may be a better modality in detecting tip position and aid in line manipulation. We assessed the accuracy of plain radiographs in determining PICC line tip position compared with using targeted neonatal(More)
Swizzling is a mechanism used by OODBs and persistent object systems to convert pointers from their disk format to a more efficient in-memory format. Previous studies of swizzling have focussed on analyzing the CPU overhead of pointer translation and studying trade-offs in different approaches to swizzling. In this paper, we show that there is an additional(More)
OBJECTIVE Assess association of NICU size, and occupancy rate and resource utilization at admission with neonatal outcome. STUDY DESIGN Retrospective cohort study of 9978 infants born at 23-32 weeks gestation and admitted to 23 tertiary-level Canadian NICUs during 2010-2012. Adjusted odds ratios (AOR) were estimated for a composite outcome of(More)
