PURPOSE To investigate whether tear hyperosmolarity, a feature of dry eye disease (DED), affects central corneal thickness (CCT), corneal light reflectivity, and/or tear film reflectivity. METHODS This prospective, cross-sectional study involved 48 participants (38 with hyperosmolar tears and 10 controls with normo-osmolar tears). Symptoms and signs of DED (tear osmolarity, sodium fluorescein...
A 78-year-old woman with burn-induced cervico-mento-sternal scar contracture was scheduled for laparoscopic cholecystectomy. During inhalational induction of sevoflurane, her airway patency deteriorated. The right lateral position and assist ventilation using a breathing bag dramatically improved her airway patency.
1. Jo SH, Youn TJ, Koo BK, et al. Renal toxicity evaluation and comparison between Visipaque (iodixanol) and Hexabrix (ioxaglate) in patients with renal insufficiency undergoing coronary angiography: the RECOVER study: a randomized controlled trial. J Am Coll Cardiol 2006;48:924–30. 2. Jo SH, Youn TJ, Park JS, et al. Iodixanol is less nephrotoxic than ioxaglate in patients with renal insufficie...
BACKGROUND Contrast-induced acute kidney injury (CI-AKI) is a potential complication of radio-contrast investigations. Many organisations have published guidance documents on the prevention of CI-AKI. Our aim is to explore the scope, content, consistency, practicality in clinical practice and reasons for eventual underlying discrepancies of these documents. METHODS We searched the literature ...
BACKGROUND/OBJECTIVES Contrast-induced nephropathy (CIN) may be a severe complication to the administration of iodine-based contrast media for diagnostic or interventional procedure using radiation exposure. Whether there is a difference in nephrotoxic potential between the various agents is uncertain. We aimed to perform a systematic review and network meta-analysis of randomized trials on iod...
OBJECTIVE Pancreatitis is the most common and serious complication of endoscopic retrograde cholangiopancreatography (ERCP). Several studies have compared contrast media (CM) with different osmolalities, but the results are conflicting. We conducted this study to clarify the difference between 2 CM used in ERCP. METHODS Five hundred and seventy-six patients were examined by using ERCP in our ...
Diamond and Bossert (1) proposed a model of standing-gradient osmotic flow as a mechanism to explain the coupling of water and solute transport in epithelia. In their computations they used a digital program in F O R T R A N on an IBM 7094 to solve for the two dependent variables, C and v, where C was the osmolar concentration at any point, x along the channel and v was the linear velocity at t...
