JOURNAL FREE ACCESSNine hundred and fifty one cases of epistaxis were observed for the past 7 years. Epistaxis was observed more frequently in males than in females and was frequently observed in children.
It occured more frequently from May to August, showing a peak in June.
The negative correlation was observed statistically between the frequency of epistaxis and the atmospheric pressure.
Hemorrhagic diathesis was examined in 114 cases. About 28 per cent of them showed abnormality, especially in the capillaly fragility.
Children with nasal bleeding showed the tendency of disliking of foods containing vitamine C.View full abstractDownload PDF (678K) -

JOURNAL FREE ACCESSThe effect of local anoxia upon the endocochlear potential (EP) was examined by pressing the labrinthine artery for 10 to 120 minutes on 30 normal guinea pigs. The EP started to decline within a few seconds after cessation of the blood supply and the survival time (the time elapsed to reach 0mV)was 48.8±8.0 seconds. After the varying period of anoxia, the pressure was released to reestablish the blood suppy and the effect of re-oxygenation upon the EP was examined.
In animals subjected to 10 to 20 minutes' anoxia, the EP returned to the preischemic level by the release. When the duration of anoxia was 30 milnutes or longer, the recovery of the potential was incomplete and the duration of anoxia was directly related to the recovery of EP. In other words, the longer the duration of anoxia is, the lower the level of the EP after re-oxygenation.
It should be noted that the EP showed the recovery to the level of+20 to 40 mV even after 120 minutes of anoxia. The possible role of transient anoxia on sudden deafness was discussed based on these results.View full abstractDownload PDF (1009K) -

JOURNAL FREE ACCESSPrimary carcinoma of the nasal septum is extremely rare and only 45 cases have been reported in Japan. Recently, a patient with carcinoma simplex arising from the anterior portion of the nasal septum was seen in our Hospital. A radical operation was performed. Eight months later, however, there was a recurrence, and hte patient has been successfully treated with irradiation.
Of the 45 cases reported, 15 originated in the anterior portion of the nasal septum, 9 in the cartilagenous part, 5 in the tuberculum septi nasi, 5 in the posterior border, and 1 in the osseous part. Histologically, 8 cases were squamous cell carcinoma, 6 basal cell carcinoma, and 5 adenocarcinoma, and 5 carcinoma simplex. Melanoma and transitional cell carcinoma were rare.
The treatment of primary septal carcinoma varies depending on the location and size of the tumor and with the presence or absence of invasion into the adjacent structures. Combined surgery and irradiation should be the treatment of choice.View full abstractDownload PDF (1065K) -

JOURNAL FREE ACCESSUnter den Krankheitsfällen, die über Schwindel klagen, findet man nicht selten Prodromalsymptome schwerer Krankheiten oder Initialsymptome von Hirntumor usw.
Neben der Schwindelbeschwerde, dem subjektven Symptom der Patienten, lassen sich auch die objektiven Symptome Spontan-und Provokations-Nystagmus feststellen. Hierhin liegt auch der Grund für die in den letzten Jahren die Forschung in Bezug auf Spontan-Nystagmus, über deren Bedeutung man sich mehr und meter hewusst geworden ist. Tatsache ist jedoch, dass vom pathophysiologischen Aspekt aus betrachtet uber Schwindel noch viel Dunkel herrscht.
Wir haben deshalb aufgrund von Untersuchungen Genaueres über die Mechanismen, die beim Zuatandekommen von Spontan-und Provokations-Schwindel wirken, zu ergründen versucht, wobei wir erstere an einem Krankengut mit Morbus Ménière, akuten Labyrinthf unktionsausfall sowie Innenohrentzündungen, letztere bei Lageschwindel vom gut-bzw. bösartigen paroxysmalen Typ sowie bei Zervikalschwindel anstellten.
Die Verfasser haben insbesondere Schuknechts mechanische Erklärung über den Lageschwindel vom gutartigen paroxysmalen Typ zum Anlass seiner Forschung, da er glaubte these
Art von Schwindel durch einen funktionelleren Mechanismus erklärbar machen zu können. Desweiteren hat der Autor die Zusaznmenhänge von "Bruns-Syndrom" und "akutem Unterwurmsyndrom" beim Lageschwindel vom bösartigen paroxysmalen Typ ereörtert und dabei betont, dass Storung im Vestibulariscerebellum die Hauptursache bei der Entstehung dieser Erkrankungen sind.View full abstractDownload PDF (1876K) -

JOURNAL FREE ACCESSWhen a man looks around while on a revolving object, nystagmus is elicited. This type of nystagmus consists of two components, i.e. optokinetic nystagmus and labyrinthine nystagmus. Labyrinthine nystagmus is caused by the movement of endolymph in the semicircular canals and can be elicited by rotating the body in the dark room with the eyes opened (perrotatory nystagmus). Optokinetic nystagmus can be elicited by applying visual stimuli with the eyes opened.
Optokinetic nystagmus may or may not be affected by additionally induced rotation nystagmus. It is also known that labyrinthine nystagmus is inhibited by gaze. In the present study electronystagmographic study was performed on the effect of concomitant perrotatory nystagmus (as induced by pendular rotation of the body) on the pattern of optokinetic nystagmus and the inhibitory effect of gaze on perrotatory nystagmus.
The subjects were 20 healthy adults. In all subjects an inhibitory effect of gaze on perrotatory nystagmus was noted. The effect, however, was complete (total suppression of perrotatory nystagmus) in 39% of the cases and incomplete (the nystagmus still appeared though diminished in frequency and amplitude) in the other 61%.
Optokinetic nystragmus was demonstrated in all cases. When a stimulus of pendular rotatory movements was applied to the subjects while optokinetic nystagmus was being elicited, no appreciable changes were observed in 39% of cases. In the remaining 61% of the cases, clearly noticeable changes in the slow component of the optokinetic nystagmus were observed.
In the group whose perrotatory nystagmus was inhibited incompletely, the changes of the optokinetic nystagmus by the rotation was more clealy observed than in the group whose perrotatory nystagmus was inhibited completely.
This finding suggests that the inhibition of labyrinthine nystagmus by gase should be taken into account when interaction between optokinetic nystagmus and labyrinthine nystagmus is studied.View full abstractDownload PDF (1640K) -

JOURNAL FREE ACCESSTomograms including 127 frontal projections and 60 lateral projections from the normal temporal bones were examined and the following results were obtained.
1. The ossicles were best visualized at a level of 1.7±5.0mm posterior to the porus acusticus externus on frontal projection, and at a level of 31.3±5.1mm medial to the auricle on lateral projection.
2. On the frontal projection, all information, concerning the middle ear cleft was possible to be obtained from the four different planes; cochlear, transitional, vestibular and mastoid planes which were taken with the distance of 2.5mm between each cut.
3. On the frontal projection with 4 different planes, the ossicles, spur, the horizontal portion of the facial nerve, the external auditory canal, the middle ear cavity, the cochlea, the vestibule, the internal auditory canal, the lateral and anterior semicircular canals, the mastoid antrum and mastoid cells were identified in all of the cases examined. However, the figue differences of each structure described above temporal bones were inevitable.
The vestibular window was observed in 96% of the cases examined, mastoid tegmen in 94%, the pyramidal eminence in 90%, the Körner's septum in 97%. On the other hand, the tegmen of the attic was observed only in 48%, and the stapes in 14%, and then these figures did not seen to offer sufficient information for the diagnosis the middle ear cleft.
4. In 60 tomograms with the laternal projection, one cut of the ossicular plane may include all information pertaining to the important structures in the middle ear cleft, The head and handle of malleus, the incus body, the long process of incus, tegmen tympani, the vertical portion of the facial canal were identified in 100% of the cases. With the slight difference in their shape. The anterior tympanic spine was observed in 85% and the mastoid clearly visualizd in 75% of the cases.View full abstractDownload PDF (2227K) -
SHORT-TERM HOSPITALIZATION AND LONG-TERM FOLLOW-UPEISHI YAMAMOTO1978 Volume 81 Issue 7 Pages 713-721

JOURNAL FREE ACCESSA review was made on 331 cases of head and neck malignancies above the age of 65 with special reference to the therapeutic dosis of irradiation and duration of hospitalization. With exception of terminal cases, the duration was within 10 days on the average and the irradiation dose have been decreasing in general by combining minor surgical procedures such as local debridement mainly on out-patient basis. The author argued that the short-term hospitalization and long-term follow-up with a close observations on the general condition and local findings of the patient would be an ideal approach for the treatment of head and neck malignancies particularly for the aged. The author suggested that a similar strategy would be applicable to most cases of head and neck malignancies and it would lead to the establishment of the so-called primary care system.View full abstractDownload PDF (549K)
