The olfactory test battery "Sniffin'Sticks" comprises a perception threshold test, an odour discrimination test and an odour identification test. The purpose of this study was to examine the suitability of the Sniffin'Sticks for use in everyday practice and to obtain (at least provisional) normal values. Thirty normosmic and 15 anosmic volunteers were examined with the Sniffin'Sticks and the "University of Pennsylvania Smell Identification Test" (UPSIT). All three Sniffin'Sticks tests distinguish between normosmics and anosmics in a highly significant manner. The good correlation of the individual tests with each other and with the results of the UPSIT documents the reliability of the test results. Critical mention must be made of the overly complex determination of the olfactory threshold. In conclusion, the Sniffin'Sticks test battery provides a validated instrument adapted to European conditions for the examination of olfactory disorders. It has proven successful in everyday clinical practice and constitutes a major aid for compiling medical certificates.
Abstract:Background. To analyze the results in early (stage I and II) glottic carcinoma of a single institution with a patientoriented concept.Methods. After diagnostic workup and multidisciplinary counseling, either radiotherapy or CO 2 laser surgery was chosen with respect to the patient's preference.Results. Sixty-five patients underwent laser surgery and 75 had radiotherapy. For T1 tumors, the 5-year overall survival, disease-specific survival, and initial local control rate after laser surgery and radiotherapy were comparable (OS, 85% vs 88%; DSS, 96% vs 93%; LCR, 86% vs 85%). In contrast, initial local control for T2 tumors was significantly more favorable after surgery (OS, 83% vs 78%; DSS, 83% vs 88%; LCR, 89% vs 67%). Larynx preservation was significantly higher after surgery in T1 tumors (96% vs 82%) and in T2 tumors (89% vs 77%).Conclusions. Selection of the treatment modality according to patient's preference results in a comparable control of disease for T1 tumors. The initial local control for T2 tumors is significantly better after surgery. In both stages laser surgery warrants a better larynx preservation rate.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
