Speech intelligibility and subjective benefit in single-sided deaf adults after cochlear implantation.

Treatment with cochlear implants (CIs) in single-sided deaf individuals started less than a decade ago. CIs can successfully reduce incapacitating tinnitus on the deaf ear and allow, so some extent, the restoration of binaural hearing. Until now, systematic evaluations of subjective CI benefit in post-lingually single-sided deaf individuals and analyses of speech intelligibility outcome for the CI in isolation have been lacking. For the prospective part of this study, the Bern Benefit in Single-Sided Deafness Questionnaire (BBSS) was administered to 48 single-sided deaf CI users to evaluate the subjectively perceived CI benefit across different listening situations. In the retrospective part, speech intelligibility outcome with the CI up to 12 month post-activation was compared between 100 single-sided deaf CI users and 125 bilaterally implanted CI users (2nd implant). The positive median ratings in the BBSS differed significantly from zero for all items suggesting that most individuals with single-sided deafness rate their CI as beneficial across listening situations. The speech perception scores in quiet and noise improved significantly over time in both groups of CI users. Speech intelligibility with the CI in isolation was significantly better in bilaterally implanted CI users (2nd implant) compared to the scores obtained from single-sided deaf CI users. Our results indicate that CI users with single-sided deafness can reach open set speech understanding with their CI in isolation, encouraging the extension of the CI indication to individuals with normal hearing on the contralateral ear. Compared to the performance reached with bilateral CI users' second implant, speech reception threshold are lower, indicating an aural preference and dominance of the normal hearing ear. The results from the BBSS propose good satisfaction with the CI across several listening situations.

Short- and mid-term effects of a setting based prevention program to reduce obesity risk factors in children: a cluster-randomized trial.

BACKGROUND & AIMS: To assess the effects of a low cost behavioral prevention program in a preschool setting. METHODS: 64 Kindergartens in 4 Bavarian regions were randomly assigned as intervention or controls in a 2:1 ratio. Samples of 1318 and 1340 children examined in the school entrance health examination at 5.7+/-2.6 and 17.6+/-2.3 months (mean+/-standard deviation for first and second sample) after the start of the program were analysed. MEASUREMENTS: Main outcome measures were the prevalence of high fruit and vegetable consumption, low consumption of high caloric drinks assessed in parental questionnaires, overweight and obesity, and secondary, further dietary habits and results of motoric testing. RESULTS: The program led to an increased proportion of children with high fruit and vegetable consumption already after 6 months, which was sustainable with adjusted odds ratios of 1.59 (1.26: 2.01) and 1.48 (1.08: 2.03) after 18 months. Subgroup analyses by gender, overweight and parental education, performed in order to assess consistency of effects, showed similar results. Prevalence of overweight and obesity as well as motoric testing results were not statistically different between intervention and control groups. CONCLUSION: This low cost setting based behavioral intervention achieved sustainable effects on fruit and vegetable consumption in young children 18 months after the start of the intervention and showed effects also in the high risk groups of children from families with lower education levels, and children already overweight.

Rapid progression of Myelodysplastic syndrome to acute myeloid leukemia on sequential azathioprine, IFN-beta and copolymer-1 in a patient with multiple sclerosis.

A woman with relapsing-remitting multiple sclerosis (MS) was treated with oral azathioprine (AZA) for 4 years and subsequently switched to interferon-beta1a. Five years later, leukopenia developed and resolved after interferon was discontinued; MS treatment was changed to copolymer-1. Recurrent pancytopenia subsequently led to diagnosis of myelodysplastic syndrome (MDS) with deletion of the long arm of chromosome 5 (MDS 5q-). Within several months, unusually rapid for this subtype, MDS progressed to secondary acute myeloid leukemia. While AZA is the probable cause for the chromosomal deletion and MDS, combined or sequential immunomodulatory therapies may permit clonal expansion of malignant hematopoietic progenitors.
