Nowadays, in several countries, nationwide screening programmes are carried out. Much less attention has been paid to the next step, namely treatment of very young hearing-impaired children with hearing devices. A review of published data indicate that the DSL (Desired Sensation Level) hearing aid prescription method, developed especially for young children, is at least a good point to begin hearing aid fitting. DSL target values for gain and output seems to be adequate for young children. Documenting the benefit for hearing aid use in young children is still cumbersome. One option is to measure the development of basal auditory functions. A review of available data showed that for this purpose, speech material can only be used in children of 3 years and older. For children of 1 year and older, tests with environmental sounds can be applied. It is concluded that, although growing, there is a lack of tests and limited knowledge on how to optimize hearing aid fittings and how to document hearing aid benefit in toddlers.","PeriodicalId":76516,"journal":{"name":"Scandinavian audiology","volume":"30 1","pages":"61 - 67"},"PeriodicalIF":0.0,"publicationDate":"2001-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1080/010503901750166682","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"59014898","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In cases of tinnitus the parameters of its character were done. All of our patients underwent X-ray investigations, i.e. ear X-ray by Schu¨ller and Stenvers methods, computerized tomography or magnetic resonance imaging. In some cases phoniatric and logopaedic examinations were performed. For aetiological diagnosis electrophoresis and immunological test (IgG and IgM against mumps) were carried out. The results were presented in two groups of patients with sudden and those of long lasting progressive unilateral deafness. Some of the patients were pharmacologically treated before the evaluation.

The database contains detailed information on the patient history, signs and test results necessary for the diagnostic work with vertiginous patients. The pattern recognition method was used in the reasoning process. Questions regarding symptoms, signs and test results are weighted and scored for each disease, and the most likely disease is recognized from the defined disease profiles. Uncertainties in reasoning, caused by missing information, were solved with a method resembling fuzzy logic. We have also applied adaptive computer applications, such as genetic algorithms and decision trees, in the reasoning process. In the validation the expert system ONE proved to be a sound decision maker, by solving 65% of the cases correctly, while the physicians' mean was 69%. To improve the expert system ONE further, a follow-up should be implemented for the patients, to ease the diagnostic work of some difficult diseases. The six diseases were detected with high accuracy also with adaptive learning methods and discriminant analysis. An expert system is a practical tool in otoneurology. We aim to construct a hybrid program for the reasoning, where the best reasoning method for each disease is used.","PeriodicalId":76516,"journal":{"name":"Scandinavian audiology","volume":"70 1","pages":"90 - 91"},"PeriodicalIF":0.0,"publicationDate":"2001-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1080/010503901300007182","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"59013620","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Agreement between the raters was assessed, and three notch characteristics, frequency, depth and shape (a wide or narrow notch), were investigated as recognition factors. The proportions of positive tests reported by each rater were 0.26, 0.49 and 0.68, respectively. The 'all rater' index of agreement was 0.45, and the range for pairwise comparisons was 0.14 to 0.52. With recognition factors, rater 1 was most strongly influenced by depth, rater 2 by shape and rater 3 by a possible combination of criteria. To reduce variability we suggest that narrow notches should be at least 15 dB in depth, and that broad notches should have a depth of 20 dB, with a recovery of at least 10 dB at the high end. Care should also be taken to elicit a sufficient history of noise exposure, and ensure that there are no other explanations for the notch.","PeriodicalId":76516,"journal":{"name":"Scandinavian audiology","volume":"30 1","pages":"106 - 111"},"PeriodicalIF":0.0,"publicationDate":"2001-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1080/010503901300112211","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"59014433","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
