conclusions the cannulation of the central vein in neonates and children in a skilled hand would be performed with great success rate and low complications. results there were 1340 newborn patients (first 28 days of life) in our study population. in these newborns, only 55 cannulations failed; one patient was complicated with pneumothorax; guide wires malfunctioned in 21 cases; and first- attem...

The issue of ‘rigour vs. relevance’ in IS research has generated an intense, heated debate for over a decade. It is possible to identify, however, only a limited number of contributions on how to increase the relevance of IS research without compromising its rigour. Based on a lifecycle view of IS research, we propose the notion of ‘reality checks’ in order to review IS research outcomes in the...

purpose: to compare visual outcomes after deep anterior lamellar keratoplasty (dalk) between eyes with and without successful big-bubble formation. methods: in this retrospective comparative study, a total of 290 consecutive eyes from 257 keratoconus-affected patients underwent dalk with the big-bubble technique were enrolled. in cases where the big bubble could not be accomplished, manual stro...

The Gaia satellite was selected as a cornerstone mission of the European Space Agency (ESA) in October 2000 and confirmed in 2002 with a current target launch date of 2011. The Gaia mission will gather on the same observational principles as hipparcos detailed astrometric, photometric and spectroscopic properties of about 1 billion sources brighter than mag V = 20. The nature of the measured ob...

We consider the accuracy of linear interpolation in predicting which subsegment contains a random key, given that the key is contained in a particular segment consisting of a fixed number of subsegments. We assume that keys are stored in a file in sorted order, that the file is divided into fixed-size segments, and that the first key in the segment containing the desired key is known, as is the...

AIM To evaluate the success rate and complications of pneumatic retinopexy performed at a university hospital and to identify which patients are best suited for pneumatic retinopexy. METHODS This was an interventional case series. Retrospective review of 61 patients who had pneumatic retinopexy performed by two retina surgeons at two University of California, San Francisco hospitals between 1...
