Results: Hearing loss was present

in 73% (73/100) of cases evaluated. Permanent hearing Combretastatin A4 in vitro losses (SNHL, ANSD and mixed) constituted 76% of losses. Unilateral hearing losses constituted 8% of SNHL and 20% of conductive hearing loss. ANSD was diagnosed in 21.4% and SNHL in 78.6% of permanent non-conductive hearing loss cases. The most prevalent SNHL risk was family history of hearing loss and for ANSD it was admittance to the NICU for more than 5 days. The majority of the sample was diagnosed with a permanent bilateral SNHL and ANSD after 36 months of age (47%) despite 40% already suspected of having a hearing loss before 12 months of age.

Conclusions: A high prevalence of ANSD was found with preventable risk factors often indicated. Age of diagnosis was significantly delayed, evidencing the lack of early hearing detection services in South Africa. The majority of children were diagnosed at ages precluding IACS-10759 cell line optimal benefits from

early detection and subsequent intervention. (C) 2012 Elsevier Ireland Ltd. All rights reserved.”
“Background: Home mechanical ventilation is usually started in hospital as arterial blood gas sampling is deemed necessary to monitor CO2 and O-2 adequately during institution of ventilatory support. A non-invasive device to reliably measure CO2 transcutaneously would alleviate the need for high care settings for measurement and open the possibility

for home registration. Objectives: In this study we investigated whether the TOSCA (R) transcutaneous CO2 (PtcCO(2)) measurements, performed continuously during the night, reliably reflect arterial CO2 (PaCO2) measurements in adults with chronic respiratory failure. Methods: Paired measurements were taken in 15 patients hospitalised to evaluate their blood gas exchange. Outcomes were compared 30 min, CB-839 mechanism of action 2, 4, 6 and 8 h after attaching the sensor to the earlobe. A maximum difference of 1.0 kPa and 95% limits of agreement (LOA) of 1 kPa between CO2 pressure measurements, following the analysis by Bland and Altman, were determined as acceptable. Results: Mean PtcCO(2) was 0.4 kPa higher (LOA -0.48 to 1.27 kPa) than mean PaCO2 after 30 min. These figures were 0.6 kPa higher (LOA -0.60 to 1.80 kPa) after 4 h, with a maximum of 0.72 kPa (LOA 0.35 to 1.79 kPa) after 8 h. The corresponding values for changes in PtcCO(2) versus PaCO2 were not significant (ANOVA). Conclusions: PtcCO(2) measurement, using TOSCA, is a valid method showing an acceptable agreement with PaCO2 during 8 h of continuous measurement. Therefore, this device can be used to monitor CO2 adequately during chronic ventilatory support. Copyright (C) 2011 S. Karger AG, Basel”
