[ENT aspects of rhino-sinusitis in children (author's transl)].
Inflammations of the nose and paranasal sinuses in children are quite different from those occurring in adults, and are due to anatomical, immunological and physiological causes. Special attention is given to the diagnosis and management of so-called "recurrent" rhino-sinusitis of childhood, which can also be caused by certain syndromes such as cystic fibrosis, Kartagener's Syndrome and Non-motile Cilia Syndrome. Clinical examples of these disturbances of nasal secretion are discussed as are disturbances of the immune system (such as the Bruton-type of agammaglobulinemia).
Endocrine-amphicrine enteric carcinoma of the nasal mucosa.
A 39-year-old bus driver had been suffering for 2 years from a malignant polypoid mucosal proliferation of the upper nasal concha-ethmoid region, resembling a highly differentiated, villous-glandular adenocarcinoma of enteric type. There were numerous mono- and amphicrine cells and a massive quantity of oxyphilic, frequently Paneth-like goblet cells in the tumor. Immune-histochemically, a number of gastrin- and fewer glucagon-positive cells were identified. The somatostatin level in the serum was clearly increased. Electron-microscopically, 7 different endocrine cell types were identifiable, in order of decreasing frequency: A-like- and G-cells, both types of 5-HT-cells, A-cells, EG- and K-cell-like elements. Particularly impressive were the muco-argyrophilic amphicrine cells, containing A-granules. The unusual enteric character of the carcinoma seems to result from boundary movements and tissue displacements in an ecto-entodermal embryonic border region. There was no history of occupational wood dust inhalation.

Comparison of the TEMPO+ ear-level speech processor and the cis pro+ body-worn processor in adult MED-EL cochlear implant users.
A study was conducted to compare the new MED-EL TEMPO+ ear-level speech processor with the CIS PRO+ body-worn processor in the COMBI 40/COMBI 40+ implant system. Speech tests were performed in 46 experienced subjects in two test sessions approximately 4 weeks apart. Subjects were switched over from the CIS PRO+ to the TEMPO+ in the first session and used only the TEMPO+ in the time between the two sessions. Speech tests included monosyllabic word tests and sentence tests via the telephone. An adaptive noise method was used to adjust each subject's scores to approximately 50%. Additionally, subjects had to complete a questionnaire based on their 4 weeks of experience with the TEMPO+. The speech test results showed a statistically significant improvement in the monosyllabic word scores with the TEMPO+. In addition, in the second session, subjects showed a significant improvement when using the telephone with the TEMPO+, indicating some learning in this task. In the questionnaire, the vast majority of subjects found that the TEMPO+ allows equal or better speech understanding and rated the sound quality of the TEMPO+ higher. All these objective and subjective results indicate the superiority of the TEMPO+ and are mainly attributed to a new coding strategy called CIS+ and its implementation in the TEMPO+. In other words, based on the results of this study, it appears that after switching over from the CIS PRO+ to the TEMPO+, subjects are able to maintain or even improve their own speech understanding capability.
