Towards a Consensus on an ICF-Based Classification System for Horizontal Sound-Source Localization.

The study aimed to develop a consensus classification system for the reporting of sound localization testing results, especially in the field of cochlear implantation. Against the background of an overview of the wide variations present in localization testing procedures and reporting metrics, a novel classification system was proposed to report localization errors according to the widely accepted International Classification of Functioning, Disability and Health (ICF) framework. The obtained HEARRING_LOC_ICF scale includes the ICF graded scale: 0 (no impairment), 1 (mild impairment), 2 (moderate impairment), 3 (severe impairment), and 4 (complete impairment).

Psychometric properties of the English version of the Audio Processor Satisfaction Questionnaire (APSQ).

Evaluating the Revised Work Rehabilitation Questionnaire in Cochlear Implant Users Cochlear Implant Outcome Assessment Based on the International Classification of Functioning, Disability, and Health (ICF).

Objectives: The 59-item Work Rehabilitation Questionnaire (WORQ) was developed based on the International Classification of Functioning, Disability and Health (ICF) core set for vocational rehabilitation to assess work related functioning. It was revised to include 17 questions, assigned to 14 ICF categories relevant to cochlear implant (CI) users. This cross-sectional multicenter study aimed to evaluate CI users' responses on the WORQ questions to describe and generate ICF qualifiers for the revised WORQ in CI users, forming part of a broader framework of CI outcome measures linked to the ICF.

Development and validation of the audio processor satisfaction questionnaire (APSQ) for hearing implant users.

The satisfaction experienced with using an audio processor is very important to hearing implant system users. Currently there are no measures that can be used to assess user satisfaction with an audio processor. This study aims to develop and validate a specific and standardised questionnaire that focuses on user satisfaction with their audio processor.

Assessment of early language development in Turkish children with a cochlear implant using the TEDIL test.

Objectives: To analyse language development of children with a cochlear implant (CI) in relation to length of CI use and age at implantation and to examine the suitability of the TEDIL as an assessment tool for measuring early language development in Turkish children.

Methods: A total of 119 children implanted with a CI before 5 years of age were assessed acutely on sound field thresholds, speech recognition thresholds, open-set and closed-set monosyllabic word tests, the TEDIL, categories of auditory performance (CAP), and speech intelligibility rating (SIR). The outcome scores were analysed in relation to length of CI use (3, 4, and 5 years) and age at implantation (<24 months vs.

Development and evaluation of the LittlEARS Early Speech Production Questionnaire - LEESPQ.

Objective: Universal Newborn Hearing Screening programs, now instituted throughout the German-speaking countries, allow hearing loss to be detected and treated much earlier than ever before. With this earlier detection, arises the need for tools fit for assessing the very early speech and language production development of today's younger (0-18 month old) children. We have created the LittlEARS Early Speech Production Questionnaire, with the aim of meeting this need.

Duration of focal complex, secondarily generalized tonic-clonic, and primarily generalized tonic-clonic seizures--A video-EEG analysis.

Introduction: Identifying seizures with prolonged duration during video-electroencephalographic (EEG) monitoring is of importance to inform clinicians when to start emergency treatment of seizures to prevent status epilepticus. The aims of this study were to assess the clinical and EEG seizure duration (SD) in consecutive patients with epilepsy who underwent prolonged video-EEG monitoring and to identify a seizure type-dependent time point to start emergency treatment based on the likelihood that seizures will not stop spontaneously. Furthermore, we sought to determine predictors of SD and explored the relationship between antiepileptic drug (AED) serum levels and SD.

Development and validation of a questionnaire for hearing implant users to self-assess their auditory abilities in everyday communication situations: the Hearing Implant Sound Quality Index (HISQUI19).

Conclusions: The Hearing Implant Sound Quality Index (HISQUI19) seems to be a valid tool for quantifying the self-perceived level of auditory benefit that cochlear implant (CI) users experience in everyday listening situations. Additional research is, however, required.

Objectives: To develop and validate a user-friendly instrument for quantifying the self-perceived level of auditory benefit that CI users experience in everyday listening situations.

Materials And Methods: This is a prospective, cross-sectional validation study using the LEESPQ in Turkish.

An investigation of the first lexicon of Turkish hearing children and children with a cochlear implant.

Introduction: Research on early cochlear implantation and first language milestones is limited. To compare language performance in cochlear implant (CI) users and hearing children, the establishment of normative data for both groups would be of benefit. To aid the data collection for Turkish hearing children and children with a CI diaries can be used.

Young cochlear implant users' auditory development as measured and monitored by the LittlEARS® Auditory Questionnaire: a Turkish experience.

Changes in plasma amino acid concentrations with increasing age in patients with propionic acidemia.

The objective of the study is to analyze plasma amino acid concentrations in propionic acidemia (PA) for the purpose of elucidating possible correlations between propionyl-CoA carboxylase deficiency and distinct amino acid behavior. Plasma concentrations of 19 amino acids were measured in 240 random samples from 11 patients (6 families) with enzymatically and/or genetically proven propionic acidemia (sampling period, January 2001-December 2007). They were compared with reference values from the literature and correlated with age using the Pearson correlation coefficient test.

Impact of anemia on aortic pulse wave velocity in hemodialysis patients.

Background: Recent studies indicate an increased mortality of anemic patients with renal failure when near-normal hemoglobin levels are aimed for by treatment with erythropoiesis stimulating agents. Aortic pulse wave velocity (aPWV) is a strong predictor of all-cause and cardiovascular mortality in patients with end-stage renal disease. The relationships between aPWV, hemoglobin levels and erythropoiesis stimulating agent dosage have not been evaluated to date.
