    Notes: Abstract Twenty-four normal subjects and 64 symptomatic patients with various degrees of reflux disease (24 with reflux symptoms without esophagitis and 21 with mild and 19 with severe esophagitis) underwent quantitative 24-hr intraesophageal pH monitoring. Various reflux parameters during supine, interprandial, and postprandial periods were examined by binary logistic regression and by CART analysis to determine the sensitivity and specificity to separate the various groups of subjects and patients. The distinction was excellent between asymptomatic controls and patients with severe erosive esophagitis (sensitivity and specificity both 100% by logistic regression and 95% and 88%, respectively, by CART), but discrimination was poor when asymptomatic controls were compared to symptomatic patients without esophagitis (71% and 79% by logistic regression and 75% and 92% by CART), which is the most important indication for pH recording in clinical practice. A 3-hr postprandial pH recording was inadequate to distinguish the various groups. The acidity of the reflux episodes during the night appeared to be a crucial factor in the development of severe erosive esophagitis. The duration of esophageal acid exposure was another important factor in the development of reflux lesions.

    Notes: Abstract From the start of 1994 until 1996 ten patients (eight adults and two children) received cochlear implants after careful preoperative selection in our department. Only the deaf adults implanted with the LAURA cochlear implant were included in this retrospective analysis. In this study, the additional hospital costs associated with cochlear implantations were estimated. In doing this, a differentiation was made between ‘fixed’ costs and ‘variable’ costs. In general, the average cost of cochlear implantation was 1,186,741 BF (29,418.54 EUR) per implanted adult and a direct fixed cost of 262,880 BF (6,516.62 EUR) was needed for the computer requisites. In general, the cochlear implant enhance speech-perception scores in the postlingually deafened patients as well as in the prelingually deafened adults. After intensive training, all implanted adults of the University Hospital Leuven could recognize the segmental aspects of speech with scores above the level of significance.
