In conclusion, the possibility that subtle alterations induced by the non conservative mutation in “m/m” animals might modify the perception of the melatoninergic signal is discussed in the context of melatonin action. (C) 2010 Elsevier B.V. All rights reserved.”
“BackgroundPostoperative pain management for patients with inflammatory bowel disease (IBD) can be challenging. These patients have a high tolerance to pain medication, and relative contraindications to the use of epidural analgesia, limiting the pain management options. We evaluated the effect of a single preoperative gabapentin dose on opioid consumption

for patients with IBD undergoing abdominal surgery. Secondary outcomes were postoperative pain scores,

opioid-related side effects, and patient’s length Cl-amidine of hospital stay.\n\nMethodsFollowing Research Ethics Board approval and informed written consent, patients were randomly allocated into 2 groups receiving either 600mg of oral gabapentin or placebo 1hour before the surgery. A blinded anesthesiologist recorded pain scores at rest and movement twice daily for 2 postoperative days. Also recorded were opioid consumption, time of return of bowel function, time to discharge, and opioid-related side effects on the opioid-related symptom distress scale (ORSDS).\n\nResultsSeventy-two patients completed the study. The difference in opioid consumption (P=0.4169) and pain scores measured at rest and movement on all 4 postoperative visits was not statistically significant. There was no significant difference between gabapentin and placebo on all the 11 symptoms reported on the ORSDS. There was a slight increase

ZD1839 in length of hospital stay in the placebo group, selleck screening library but the return of bowel function was similar between the groups.\n\nConclusionsThis study examined the effect of a single preoperative administration of gabapentin in patients with IBD undergoing major bowel surgery. Our results suggest a single preoperative oral dose of gabapentin 600mg does not reduce postoperative pain scores, opioid consumption, or opioid-related side effects.”
“The objective of this study was to explore cochlear implant users’ speech perception performance in quiet and in noise for low to moderate stimulation rates. Eight postlingually deaf adult users of the Nucleus CI24 cochlear implant (contour electrode array) using the ESPrit 3G speech processor participated in this study. Monosyllabic word recognition in quiet and sentence perception in noise was evaluated for low to moderate stimulation rates of 275, 350, 500, and 900 pulses-per-second/channel (pps/ch). All four stimulation rate programs were balanced for loudness. A repeated ABCD experimental design was employed. Take home practice was provided with each stimulation rate. Subjects also responded to a comparative questionnaire to examine their rate preference for a variety of listening situations.
