The Mean

A total of 190 individuals participated in a clinical visit during the Cooperative Studies Program (CSP) 418-A Long Term Follow-Up Study. Of this cohort, 158 participants were considered current hearing aid users, and 32 were non–hearing aid users. Of the current hearing aid users, 81 were still using their original 418 study devices, and 77 had acquired new hearing aids. Coupler and real ear measurements were completed on all available hearing aids. Results showed that study aids had remained relatively stable over the six years between CSP 418 and CSP 418-A. On average, these hearing aid wearers preferred use gain settings that were 6–9 dB less than current NAL-RP insertion gain targets. Mean real ear insertion gain (REIG) was comparable to the mean real ear insertion gain of the same participants in the original study, and users did not tend to increase gain as hearing decreased. Real ear saturation responses (RESR) remained unchanged. Loudness discomfort levels (LDL) obtained during 418-A were significantly lower than LDLs obtained on those same participants at both the initial and final visits in the previous study. Un total de 190 individuos participaron de la visita clínica durante el Estudio de Seguimiento a Largo Plazo 418-A del Programa de Estudios Cooperativos (CSP). De esta cohorte, 158 participantes se consideraron usuarios actuales de auxiliares auditivos (AA), y 32 se consideraron no usuarios de AA. De los usuarios actuales de AA, 81 aún utilizaban sus dispositivos 418 del estudio, y 77 había adquiridos nuevos AA. Se completaron mediciones de acoplador y de oído real para todos los AA disponibles. Los resultados mostraron que los AA del estudio había permanecido relativamente estables en los seis años entre el CSP 418 y el CSP 418-A. En promedio, estos usuarios de AA prefirieron el uso de ajustes de ganancia que estaban 6-9 dB por debajo de las metas actuales de ganancia de inserción del NAL-RP. La ganancia media de inserción de oído real (REIG) fue comparable con la ganancia media de inserción de oído real de los mismos participantes en el estudio original, y los sujetos no tendieron a incrementar la ganancia conforme la audición se deterioró. Las respuestas de saturación de oído real (RESR) se mantuvieron sin cambio. Los niveles de incomodidad a la intensidad subjetiva (LDL) obtenidos durante el 419-A fueron significativamente más bajos que los LDL obtenidos en los mismos participantes, tanto en la visita inicial como final del estudio previo.

Long Term Follow Up

This report provides background regarding the Long Term Follow-Up of Patients in the NIDCD/VA Hearing Aid Clinical Trial study and serves as an introduction to the detailed reports that follow in this issue of Journal of the American Academy of Audiology. The authors investigated five- to seven-year benefit/satisfaction in participants from the original NIDCD/VA Hearing Aid Clinical Trial. The new study was designed to investigate current use of the original study hearing aids, to compare changes in selected audiological measures, and to assess possible predictors of long-term hearing aid use. The outcome measures included estimates of speech intelligibility in quiet and noise, self-reported patterns of hearing aid usage, self-reported estimates of activity limitations and quality-of-life issues, estimates of hearing aid satisfaction, and self-reported hearing aid benefit. Overall, the short-term benefits of hearing aid use observed during the original trial were noted to persist in the long term. Este reporte suministra información relacionada con el Seguimiento a Largo Plazo de los Pacientes del Estudio Clínico de Auxiliares Auditivos del NIDCD/VA, y sirve como una introducción de los reportes detallados que siguen a continuación en esta edición del Journal de la Academia Americana de Audiología. Los autores investigaron por cinco a siete años la satisfacción/beneficio en los participantes del Estudio Clínico de Auxiliares Auditivos del NIDCD/VA original. El nuevo estudio fue designado para investigar el uso actual de los auxiliares auditivos (AA) originales del estudio, para comparar cambios en las medidas audiológicas seleccionadas, y evaluar posibles elementos de predicción a largo plazo en el uso de AA. Las medidas de resultado incluyeron estimados de la inteligibilidad del lenguaje en silencio y en ruido, patrones auto-reportados de uso del AA, estimaciones auto-reportadas de limitación en la actividad y en asuntos de calidad de vida, estimaciones de satisfacción en el uso del AA y auto-reportes de beneficios con el AA. Globalmente, los beneficios a corto plazo del uso de auxiliares auditivos durante el estudio original persistieron en el largo plazo.

The Mean

A recent development in hearing aids, the contralateral routing of signals (CROS), makes it possible to provide amplification for persons with unilateral hearing loss. In 1967, a CROS eyeglass hearing aid was placed on government contract and made available to veterans. To study the efficiency of the CROS, a follow-up questionnaire was sent to 60 male veterans who had been fitted with this aid. All had demonstrated unilateral hearing losses, and the mean threshold for the speech frequencies (500–2000 Hz) in the good ear was 24 dB. The 54 replies (90%) indicated that 85% wore the aid, liked it, and derived benefit from it; 15% neither liked nor wore the aid. The CROS appeared to be most helpful in listening to conversational speech and at work, and most disturbing in a noisy environment. The complaints about the aid fell into major categories: 33% objected to its poor fit and construction and 11% were disturbed by speech distortion. The CROS aid has been a useful addition to the hearing-aid stock at the clinic reported here. It has expanded the program by providing amplification to veterans who could not be fitted with the conventional stock of aids.

The Mean

A follow-up study of 49 individuals with paroxysmal atrial tachycardia in infancy is reported. Forty subjects had supraventricular tachycardia and nine had atrial flutter/fibrillation. The mean follow-up period was 24 years. Males whose ECGs showed preexcitation displayed the highest rate of recurrences (approximately 60%) in the long-term follow-up. Approximately 30% of the subjects without preexcitation in the ECG displayed episodes of supraventricular tachycardia in their third decade. Eighty-six percent of the children of the subjects in the present series were males. The prognosis is good in the absence of congenital heart disease.

The Mean

Eighteen macrocephalic children with enlargement of the subarachnoid space (ESAS), with or without mild ventricular dilatation, were followed prospectively to a mean age of 56 months. All were born at term, with uneventful neonatal period and negative tests for congenital infections. There were 17 boys and 1 girl and the mean follow-up period was 46 months (8-58 months). The initial neurologic evaluation, between ages of 2 to 33 months, disclosed abnormalities in 2 cases. At the follow-up one was still abnormal and the other had a normal neurological examination. Another child, who had a normal neurological examination at the age of 5 months, at the age of 7 years and 7 months had an IQ of 77. Thus the abnormality rate at follow-up was 11%. The OFC returned to the normal range in 45% of the children at the follow-up period. There were no cases of intracranial hypertension. One infant had subdural taps performed at the age of 13 months that disclosed a fluid with the same characteristics as the CSF. All the children had a CT-scan performed at the beginning of the study that revealed a large subarachnoid space; in 77% it was associated with mild ventricular dilatation. Eleven had CT-scans repeated, during the study period, which showed resolution of the process in 3 cases, improvement in 2, and unchanged in 6. We conclude that enlargement of the subarachnoid space in macrocephalic children is often a benign entity. ESAS and macrocephaly will still be present in the majority of children in the long-term follow-up.
