A young woman who presented with loin pain and pyuria after a prolonged period of investigations and treatment, finally having a nephrectomy for non-functioning kidney, was revealed to have schistosomial infestation with an adult worm in the ureter. Unusually, she only developed bladder manifestations later.
Infants with hearing loss routinely receive hearing aids several months before reliable behavioral responses to amplified sound can be observed. This necessitates objective measures to validate hearing-aid fittings. A single report has demonstrated the use of ASSRs to determine aided thresholds in children but data in young infants is still lacking. The(More)
Speech sound distortion is considered to be a salient feature of neuromotor speech disorders such as cerebellar dysarthria and apraxia of speech. The aim of this study was to compare the temporal and spatial aspects of speech of two persons with acquired cerebellar dysarthria and of one person with acquired apraxia of speech. Voice onset time of [d],(More)
In this study, the speech of a 28-year-old male with acquired brain injury and who presents with an undefined neuromotor speech disorder which cannot be categorised as either apraxia of speech or dysarthria, is described. Voice onset time, vowel duration, utterance duration and vowel formant analyses were done acoustically. A perceptual analysis and(More)
Profoundly deaf cochlear implant users provide an interesting population in which to assess the role of distorted auditory feedback in speech, since their electrically stimulated hearing is significantly different from normal hearing. The aim of the study was to evaluate, by means of spectrographic and listener analyses, the speech production changes in a(More)
The speech production changes of a postlingually deaf child and adult with a multichannel cochlear implant were spectrographically analyzed over a period of time. The segmental analysis in both case studies included the measurement of vowel, fricative, and plosive burst duration; first and second vowel formant frequency relationship; and centroid(More)
A review of the relevant literature indicates a lack of knowledge regarding suprasegmental speech characteristics in prelingual hearing impaired children with cochlear implants. This study is aimed at examining certain suprasegmental features in the speech of prelingual hearing impaired children with cochlear implants by perceptual ratings and acoustic(More)
A comprehensive voice evaluation comprises more than just the evaluation of perceptual and organic aspects. Objective voice analysis should supplement the diagnostic battery. In order to obtain normative indications for the Speech Research Laboratory at the University of Pretoria, 25 men and 25 women ranging in age from 8 to 80 years and with perceptually(More)
