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)
Background: The Four-Level Framework of speech production (Van der Merwe, 1997) suggests that language of production of a bilingual speaker can be viewed as a contextual factor increasing the complexity of speech production. A comparison of first versus second language speech production in individuals with apraxia of speech or phonemic paraphasic speech… (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)
A 62-year-old man presented with a 2-month history of psychiatric symptoms. These were preceded by cognitive deterioration, urinary incontinence and an abnormal gait. A diagnosis of normal-pressure hydrocephalus (NPH) was made, and the patient improved after surgery.
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)
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)
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)
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)
