A holistic model for matching high-tech hearing aid features to elderly patients.

Successful hearing aid fittings using high-technology features for elderly patients require consideration of factors beyond results obtained from routine audiologic evaluations. A holistic hearing aid selection, fitting, and evaluation approach that considers patient characteristics from communication, physical, psychological, and social assessment domains is presented here along with a checklist and flowcharts for matching high-tech hearing aid features to older persons who are hearing aid candidates.

Relationship between distortion product otoacoustic emissions and frequency modulation difference limens.

OBJECTIVE: To explore the relationship between distortion product otoacoustic emissions (DPOAEs) and frequency modulation difference limens (FMDLs) in normal-hearing subjects. DESIGN: Fifteen normal-hearing adult subjects (age range = 20 to 29 yr; mean age = 21 yr, 6 mo) participated in the study. Each subject met the following criteria: 1) hearing thresholds <20 dB HL bilaterally at frequencies 0.25 to 8 kHz; 2) type A tympanograms bilaterally; and 3) no history of otologic disease. To reduce gender-related differences, only female subjects were recruited as subjects. DPOAE amplitudes and FMDLs were measured in both ears of 15 female adults at 1, 2, and 4 kHz. Ears were classified on the basis of DPOAE amplitude into large DPOAEs and small DPOAEs. RESULTS: Results indicated that ears with larger DPOAEs showed better frequency discrimination (smaller FMDLs) than did ears with smaller DPOAEs at 2 kHz. CONCLUSIONS: Results of the current study support frequency discrimination models that predict a relationship between frequency selectivity and frequency discrimination.

Penile dermal flap for defect reconstruction in Peyronie's disease: operative technique and four years' experience in 17 patients.

Peyronie's disease is not uncommon. Despite its self-limiting nature in many patients and the multiplicity of available non-invasive treatment modalities, a few patients will eventually require surgery if deformity or impotence is severe and conservative measures have failed. Currently available operations for Peyronie's disease are less than ideal. The two most popular operations employed for this condition are the 'tucking' procedure of Nesbit (and its excision-plication variants) and the free dermal graft of Horton and Devine. In addition, many other autografts and synthetic grafts have been described by different workers. Some have used prostheses in these patients for straightening the penis in the absence of proven concomitant organic impotence. Unfortunately, none of these operations has fulfilled all desiderata. The author has worked at developing a live graft source (flap) which is free from many of the drawbacks experienced with other procedures. In this new operation, dermabraded penile dermis is raised on its vascular fascial pedicle and used to close the defect in the tunica albuginea consequent upon plaque incision. This technique is feasible in both circumcised and uncircumcised patients. This is the first report of the use of a flap in Peyronie's disease. Operative technique and results in 17 patients over 4 years are presented. The author's experience seems to suggest that this is an ideal operation for Peyronie's disease.
