over time on every test administered. According to the research findings, the two groups did not differ significantly in auditory skill development based on parental reports or behavioral assessments of spoken word recognition. The researchers also report that, compared to their peers with no additional disabilities, pediatric cochlear implant recipients with cognitive delays were significantly slower at developing auditory-only sentence recognition abilities and obtained lower scores on two of the three measures of receptive and expressive language. The researchers also report two main indications from the findings: that children with mild cognitive deficits should be considered for cochlear implantation with less trepidation than in the past, and, though children's speech and language gains may be tempered by their cognitive abilities, these limitations do not appear to preclude benefit from cochlear implant stimulation.

Cochlear Changes in Patients With Type 1 Diabetes Mellitus.
Author(s): Fukushima, H. Source: Otolaryngology-Head and Neck Surgery. 133(1):100-106. July 2005. Availability: Available from Elsevier Science. (800) 654-2452. Fax: (212) 633-3820. E-mail: email@example.com. Website: www.us.elsevierhealth.com. Language: English. Abstract: This article reports on a study that evaluated the effects of diabetes on cochlear elements. The authors examined 26 temporal bones from 13 patients with type 1 diabetes and 30 temporal bones from 17 normal cases to analyze cochlear hair cells, spiral ganglion cells, spiral ligament cells, and the areas of the stria vascularis. They found that, in people with diabetes, the wall vessels of the basilar membrane and vessels of the stria vascularis were significantly thicker in all turns and loss of outer hair cells (OHCs)was significantly greater in the lower basal turn. Atrophy of the stria vascularis in all turns and loss of spiral ligament cells in upper turns were significantly higher than controls. No significant difference was obtained in the number of spiral ganglion cells among groups. The study suggests that type 1 diabetes mellitus can cause cochlear microangiopathy and subsequent degeneration of cochlear lateral walls and OHCs. 4 figures. 20 references. (AA-M).

PRICE: $30 for a single copy, plus shipping and handling. Language: English. Abstract: This article reports on a study to assess the relative effectiveness of print, sign, and pictures in the transfer of reading-related information to children with hearing impairments. The authors report using personal computers and CD-Rom software to present stories to deaf children in four different formats: print only; print plus pictures; print plus sign language; and print, pictures, and sign combined. The article outlines the data retrieval method, research results, and findings. From their findings, the authors conclude that multimedia presentation of reading material is significantly more effective for reading comprehension than the use of print alone.

Recognition of 'Real-World' Musical Excerpts by Cochlear
Implant Recipients and Normal-Hearing Adults.
Author(s): Gfeller, K. Source: The American Auditory Society: Ear and Hearing Journal. www.amauditorysoc.org. 26(3):237-250. June 2005. Availability: Available from Lippincott Williams and Wilkins. 530 Walnut Street, Philadelphia, PA 19106-3621. (215) 521-8300. Website: www.ear- hearing.com. Language: English. Abstract: The multipurpose study reported in this article sought to compare recognition of 'real-world' music excerpts by postlingually deafened adults using cochlear implants and normal-hearing adults; compare the performance of cochlear implant (CI) recipients using different devices and processing strategies; and examine the variability among implant recipients in recognition of musical selections in relation to performance on speech perception tests, performance on cognitive tests, and demographic variables. The researchers tested 79 CI users and 30 normal-hearing adults on open-set recognition of items from classical, country, and pop music styles. According to the results, CI recipients show significantly less accurate recognition than normal-hearing adults for all three styles and no significant differences by device or strategy. The authors conclude that current-day implants do not effectively convey all salient features of music; thus, recipients are required to extract those musical features most accessible, such as song lyrics or rhythm patterns, in order to identify music heard in everyday life.

Pediatric Cholesteatoma: Canal Wall Window Alternative to
Canal Wall Down Mastoidectomy.

Language: English. Abstract: A previous pilot series described the substitution of a hybrid mastoidectomy technique, canal wall window (CWW), for the canal wall down (CWD) procedure that involved slitting the posterior canal wall. A current, larger series, reviewed in this article, compares the results of the CWW procedure with conventional surgical techniques. This retrospective study took place at an academic tertiary referral center and involved analysis of 78 pediatric ears. The mean patient age was 13.5 years. The data analyzed included ears later requiring conversion from CWW to CWD, dry/moist ear results, recidivation determined by two separate methods, and audiometric data statistically analyzed using independent- samples analysis (unpaired, two-tailed Student's t test). Based on the research results, the researchers concluded the following: frequently, a CWW procedure can be substituted for a traditional CWD procedure; in the extended series, the CWW technique continued to provide hearing results similar to CWW rather than to CWD procedures in a young
