摘要:

The present paper reports the clinicopathologic features of six cases of non-Hodgkin’s lymphoma of the larynx observed during the last 14 years. After careful clinical staging only 3 patients had isolated laryngeal lymphoma (stage IE). Radiotherapy was administered as initial treatment in all cases. These patients are alive and well after 12,6 and 1 years, respectively. Histologically, all laryngeal lymphomas of this study showed a diffuse pattern of growth. All lymphomas were of follicular center cell origin according to Lukes and Collins (29). Four cases were of low grade malignancy according to Lennert and Mohri (25), or grade I, according to the British (18) classification. The remaining two were of high grade malignancy or grade II. A careful histopathological diagnosis, which may separate other pathological conditions, and an appropriate staging, which may exclude dissemination of disease, are stressed as representing the basis for effective treatment. The applicability of current functional nomenclature is possible also in these extranodal lymphoma

摘要:

The cochlear aqueduct is the duct that connects the perilymphatic space of the scala tympani with the subarachnoid space. However, its functions are not yet fully elucidated. In the present study on the cochlear aqueduct of the guinea pig, a fracture preparation method was used to obtain certain new findings by scanning electron microscopy.

摘要:

All 3-year-old children in a region were screened by tympanometry in January 1976 (503 children), and the 6-year-olds of the same region had tympanometric and tone audiometric screening in January 1979 (498 children), 70% being included both times. Significant improvement in middle ear status had occurred from the age of 3–6 years, but otherwise there was surprisingly little difference between the two age levels, e.g., about one-third of the tympanograms were abnormal in both age groups. Ears having a middle ear pressure of 0 to –99 mm H2O at 3 years showed significantly better impedance audiology at 6 years, but as regards hearing loss they proved to be like cases who had previously had more or less negative pressure in the middle ear. Out of the flat tympanograms at 3 years a quarter were still flat at 6 years, and every sixth child did not pass tone audiometric screening. The subgroups boys/girls, nursery school/homecare children, urban/rural children that had exhibited differences in middle ear function at 3 years showed identical results at 6 years. A favourable effect of systematic tracing and active treatment of middle ear pathology from the age of 3 years could not be found at tone audiometry and impedance testing at 6 years. This must, inter alia, shake faith in adenoidectomy as a therapeutic or preventive procedure in dealing with middle ear pathol

摘要:

In many clinics and medical offices the electrographical registrations of vestibular reactions are only available for patients with special problems. For routine explorations Frenzel’s glasses are still in use. It was one purpose of our studies to show that the observation with Frenzel’s glasses is no less effective than ENG registration, in regard to nystagmus frequency. This result is based on investigations with special equipment for simultaneous registration and computerized evaluations. The disadvantage using Frenzel’s glasses without any other equipment is the impossibility of determining the culmination phase exactly. Therefore we looked for a defined period in which the frequency was correlated best to the frequency of the culmination phase determined by ENG recordings. A total of more than 100 different intervals were analyzed. The optimal period for routine investigations is a 1 min interval beginning 10 sec after the end of irrigation. Limiting the evaluation of a caloric response to this defined observation period is recommended for various re
