Of the four out of 486 cases of tympanitis, which were caused by Klebsiella pneumoniae; two of them were acute, (19 years, male; 6 years, female.) and another two were chronic (20 years, female; 7 years, female). (1) These acute cases are usually so malignant that strong resist to treatment is seen and involves complications although symptoms presented are similar to the common cases and shows rapid development of painful ear and flushing of the eardrums. (2) The clarifreation of Klebsiella pneumoniae is difficult, especially of modificational type, inspite of it's seruingly apparent finding. Klebsiella pneumoniae referred to us, were from small to medium, Gram-negative, and capsuled with both ends slightly curued. These were typed as M-type of Klebsiella pneumoniae. The viscosity and thearness of colony is the characteristic signs. (3) The treatment is usually for involving complications which is seen more of ten compared to other cases caused by gram-positive cocci. To define the causal bacterium is important from the clinical point of view, because of its specific drug therepy.
Signs and symptoms of the autonomic instability on 115 patients associated with chronic tonsillitis were examined by anamnesis before tonsillectomy and after tonsillectomy. Between the four groups, simple chronic tonsillitis, slight fever, nephritis, rheumatism, the results made no great differencies. The recovery and improvement of the symptoms were remarkable in each group; on this point, however, there were also little differencies between the four groups. These seemes after all to be the symptoms appearing in Angina habitualis, and there is a presumption of the limit that these signs are playing some roles on the developments of the focal infection
The author reported 27 cases of the chronic progressive unilateral labyrinthine deafness who were observed by the author in the period of past 9 years, and the several problems about this disease were discussed. The summary and conclusions are as follows; 1) In nearly all cases the deafness occured and developed in childhood or in the young adult stage. (26 in 27 cases, the deafness occured in the years below 20). 2) Only a few reports in literature about this disease were found. They were reviewed and discussed. 3) As the probable causes of this disease, the following three conditions were described in literature. That is, (1) subclinical mumps, (2) subclinical otitis and (3) hereditary defect. 4) From the many findings in the cases observed by the author and remarks found in the literature, subclinical mumps and subclinical otitis do not fully warrant consideration as the cause of this disease. The author believes that the hereditary defect is the most reliable cause of this disease. 5) But since there are still more unsolved problems remaining in the field of these diseases, it is hoped that further studies will be reported.
It has been said that when the rotatoric stimulations are given repeatedly, the duration of postrotatoric nystagmus decrease, but on the caloric stimulation such phenomenon dose not occur, however even in case of the caloric stimulation, response decline (R. D.) phenomenon may be caused by its different test conditions. Consequently experiments were performed on rabbits on this problem, and following results are obtained. 1) R. D. phenomenon is liable to occurred even by one-sided cold or warm irrigation at a certain interval. 2) The appearance of R. D. phenomenon depends on the temperature of irrigating water but has very littele dependance on the amount of water. 3) Warm water produces R. D. phenomenon more easily than cold water. 4) More remarkable R. D. phenomenon is caused by respective simultaneous irrigation of cold and warm water into both ears than one-sided irrigation. This may be one of the reasons that the appearance of R. D. phenomenon at the rotation test is attributed to the simultaneous stimulation of bilateral labyrinths. 5) R. D. phenomenon has no relationship with the external auditory meatus. 6) The nystagmus must always exist on the appearance of R. D. phenomenon. 7) When R. D. phenomenon appears by repeated irrigation of one ear, the nystagmus duration due to the opposite ear decrease.
Applying Shannon's communication system, the auditory system with tinnitus was assumed as a noisy discrete channel because the tinnitus was considered as a distubance in the rate of information transmission. The equation of the rate of information transmission (R) in the auditory system with tinnitus was determined according to the information theory. Practical calculation of R in the patients complaining of tinnitus was conducted from the data of their audiogram. The relation between the calculated R and loudness (db) of signal sound were charted in rectangular co-ordinates, where the ordinate and abscissa represented R and londness respectively. This was named the R-db chart. The examination of R in 20 patients complaining of tinnitus and in 9 normal persons revealed that tinnitus converts the figure of the R-db chart. Further investigation is required to determine the usefulness of the R-db chart to the differential diagnosis on the causes of tinnitus.
The Authors reported on convergence nystagmus in a 17 year old male. His chief complaints were bilateral tinnitus, bilateral hardness of hearing, and double vision. Craniotomy was performed by neurosurgeons. Postoperatively, he remained comatic and died 24 hours later. Autopsy revealed a sharply defined, hen egg sized tumor (teratoblastoma), arising from the roof of the third ventricle and was found down-words the quadrigeminate palate. Microscopically, the brain stem revealed lesions in the nuclei of the third nerve, superior olive nuclei and in the nuclei of the central grey matter. Eye movement of the nystagmus was cinematophatographed in a 16mm film.
Audiometer tests on hearing ability of one brother and two younger sisters who had blue seleras and his cousins were perfomed. Two cousins had normal hearing, but the brother and two sisters had pure perceptive deafness of abrupt high tone loss. Since their mother had blue sclera also, the authors diagnosed their perceptive deafness as one symptom of van der Hoeve's syndrom. The origin of deafness complicated with blue sclera is considered as being due to otosclerosis. According to this hypothesis, the audiogram findings showing pure perceptive type can be explained by the interpretation that characteristic otosclerotic focus invaded not the vestibular window but only the perceptive system.
