Conclusion. High frequency immittance measurements demonstrate promise in clarifying middle ear status for neonates but age-and gender-specific norms should be consulted. Objective. To describe high frequency immittance measurements using a 1000 Hz probe tone for a sample of 278 neonatal ears (0-4 weeks of age) in order to compile normative tympanometric and acoustic reflex criteria. Subjects and methods. Assessment of neonatal ears included 1000 Hz probe tone immittance measurements (tympanograms and ipsilateral acoustic reflexes), and distortion product oto-acoustic emission (DPOAE) screening. Results were compared and normative values were compiled for immittance measures in ears controlled for normal middle ear functioning (n=250). Results. Comparison of immittance results to OAE screening outcome provides estimates of sensitivity and specificity for middle ear fluid with tympanometry of 57% and 95%, and 57% and 90% for acoustic reflex presence, and 58% and 87% for combined tympanogram and acoustic reflex results, respectively. Normative data indicate that static peak admittance values differ significantly across gender and age with the 5th percentile cut-off value for the entire sample at 1.4 mmho. The 90% range of tympanic peak pressure normative values increases with increasing age from 140 daPa for neonates 1 week of age to 210 daPa for neonates 2-4 weeks of age. Acoustic reflexes were elicited at 93±9 dB with a 90% normality range of 80-105 dB.

Abstract:Objective: To determine the status of early intervention services provided to children who are deaf or hard of hearing and their parents/caregivers from birth to five years of age at two main state hospitals in Riyadh, Saudi Arabia, based on their parents' perceptions. Method: A descriptive quantitative research design was used to determine the status of early intervention services for deaf or hard of hearing children in Saudi Arabia based on their parents' perceptions. Semistructured interviews based on a questionnaire were conducted with 60 research participants from two main state hospitals where early detection and intervention services are provided. A purposive sampling technique was employed. Descriptive and inferential statistical analyses were performed on the data collected. Results: The participants' children were diagnosed at a substantially late age, resulting in delayed ages for initial hearing aid fitting and enrollment in early intervention services. A significant relationship was found between the residential area of the participants and timely access to intervention services. The results indicated that participants residing in Riyadh were fitted with hearing aids and enrolled into EI services earlier than those living outside of Riyadh. The delivery of information also emerged as a weakness in the EI system for the majority of participants.

SummaryObjective: The auditory steady-state response (ASSR) to air-conduction (AC) stimuli has been widely incorporated into audiological test-batteries for the pediatric population. The current understanding of ASSR to bone conduction (BC) stimuli, however, is more limited, especially in the case of infants and children. There are few reports on ASSR thresholds to BC stimuli in infants and young children, and none for infants or children with hearing loss. The objective of this study was to investigate BC ASSR thresholds in young children with normal hearing and various types and degrees of hearing loss. Methods: AC and BC ASSR thresholds are reported for 48 young children (mean age AE SD = 2.8 AE 1.9 years; age range = 0.25-11.5 years; 23 female). Hearing status was classified by assessing all children with a comprehensive test battery including tympanometry, diagnostic distortion-product otoacoustic emissions, click-evoked AC auditory brainstem response, AC and BC ASSR thresholds, and an otologic examination. The subjects were assigned to the categories normal hearing, conductive loss, and sensorineural loss (mild-to-moderate or severe-to-profound), for group analysis. AC and BC ASSR stimuli (carrier frequencies: 0.25-4 kHz; 67-95 Hz modulation rates; 100% amplitude and 10% frequency modulated) were presented using the GSI Audera system. Results: : Minimum levels at which spurious BC ASSR occur were established in the group of children with severe-to-profound sensorineural hearing loss (25, 40, 60, 60 and 60 dB for 0.25, 0.5, 1, 2, and 4 kHz, respectively). Children with normal hearing presented mean (1SD) BC ASSR thresholds of 19 (9), 18 (7), 16 (11), 24 (7), and 26 (8) dB HL at 0.25, 0.5, 1, 2, and 4 kHz, respectively. Significantly lower thresholds ( p < 0.0001) were obtained for 0.25, 0.5 and 1 kHz than for 2 and 4 kHz. At

BackgroundDesignated psychiatric facilities are responsible for the care, treatment and reintegration of State patients. The necessary long-term care places a considerable strain on health-care resources. Resource use should be optimised while managing the risks that patients pose to themselves and the community. Identifying unique factors associated with earlier discharge may decrease the length of stay. Factors associated with protracted inpatient care without discharge could identify patients who require early and urgent intervention.AimWe identify socio-economic, demographic, psychiatric and charge-related factors associated with the discharge of male State patients.MethodsWe reviewed the files of discharged and admitted forensic State patients at Weskoppies Psychiatric Hospital. Data were captured in an electronic recording sheet. The association between factors and the outcome measure (discharged vs. admitted) was determined using chi-squared tests and Fischer’s exact tests.ResultsDischarged State patients were associated with being a primary caregiver (p = 0.031) having good insight into illness (p = 0.025) or offence (p = 0.005) and having had multiple successful leaves of absences. A lack of substance abuse during admission (p = 0.027), an absence of a diagnosis of substance use disorder (p = 0.013) and the absence of verbal and physical aggression (p = 0.002 and p = 0.016) were associated with being discharged. Prolonged total length of stay (9–12 years, p = 0.031) and prolonged length of stay in open wards (6–9 years, p = 0.000) were associated with being discharged. A history of previous offences (p = 0.022), a diagnosis of substance use disorder (p = 0.023), recent substance abuse (p = 0.018) and a history of physical aggression since admission (p = 0.017) were associated with continued admission.ConclusionDischarge of State patients is associated with an absence of substance abuse, lack of aggression, multiple successful leave of absences and length of stay in hospital.

The lack of appropriately qualified teachers in South Africa is growing rapidly and frequency of debates about the decline in teacher numbers in South Africa is increasing. In this study, the results of an investigation into possible factors that impact on the career choice of student teachers are reported. The reasons why first-year student teachers at the University of Pretoria chose teaching as a career were studied by using a non-experimental design (survey design; administering a non-standardised questionnaire). The results revealed inter alia that a number of factors influence the career choice of first-year student teachers. Trends that emerged from the current study include the following: many more women than men enter the teaching profession; relatively few students who speak an African language choose education as a field of study and the role of parents in helping their children to choose a career cannot be underestimated.
