JOURNAL FREE ACCESSThe maintenance of upright posture in humans requires the integrative coordination of vision, proprioception and the labyrinth. In order to evaluate the roles of the labyrinth and proprioception, stabilometry was performed in patients with either bilateral severe labyrinthine disorders or severe proprioceptive disorders. In both patients both the area of sway (A) and the accumulated shift distance length (L) increased. In patients with labyrinthine disorders, A increased more than L. On the other hand, in patients with proprioceptive desorders L increased more than A. These findings thus suggest that the labyrinth therefore mainly monitors the area of the body sway while proprioception mainly monitors the length of the body sway.View full abstractDownload PDF (10196K) -

JOURNAL FREE ACCESSPregnancy related vomiting, motion sickness and dizziness were studied with questionnaires to 45 pregnant women. Nausea and vomiting was thus found to occur in 39. The incidence of pallor, palpitation, cold sweating, headache and dizziness was 21%, 15%, 21%, 21% and 54%, respectively. The symptoms of vomiting in pregnancy seemed to be similar to those in motion sickness. Motion sickness occurred most strongly in 10 while dizziness had appeared more severely in 7 after pregnancy. Those findings thus suggest that pregnancy clearly influences motion sickness and dizzinessView full abstractDownload PDF (5548K) -

JOURNAL FREE ACCESSFifty-five patients (a total of 54 ears) with otosclerosis are reviewed. All patients underwent and operation during the period from January 1987 through June 1994. We investigated the successful rate of stapedectomy and the histological findings of the stapes. The successful rate for obtaining a hearing improvement was 94%. We recognized the lesions of otosclerosis in 23 cases at operation. Twenty-two cases (96%) out of 23 cases showed lesions involving the anterior portion of the oval window. A histological examinations of the footplates revealed 26 cases (58%) out of 45 cases to have otosclerosis.View full abstractDownload PDF (9853K) -

JOURNAL FREE ACCESSThirty-two patients diagnosed to have chronic adhesive otitis media either with or without cholesteatoma were operated on by the method of intentional lateralization of the tympanic membrane. Determining whether or not the middle ear space was aerated was then analysed by CT or a second operation. The results thus indicated that 23 out of 32 cases (72%) had aerated tympanic cavities. Twenty of 32 cases (63%) had continuous otorrhea before the operation, however, only one patient demonstrated such symptoms after the operation. The effectiveness of the lateralization of the tympanic membrane as a treatment modality for adhesive otitis media is also discussed.View full abstractDownload PDF (10901K) -

JOURNAL FREE ACCESSWe report two cases of herpes zoster oticus with multiple cranial nerve involvement which is rather unusual among herpes zoster patients.
The patients consisted of a 72-year-old male (case 1) and a 61-year-old male (case 2). Both patients complained of an earache and a sore throat associated with herpetic eruptions. Physical examinations revealed involvement of the VIIth, IXth, and Xth cranial nerves in case 1, and of the V th, IXth, and Xth cranial nerves in case 2. In both cases, the administration of Acyclovir markedly improved the herpetic eruptions on the aural skin and the pharyngeal mucosa.
Cranial nerve lesions in case 2 recovered after two weeks, whereas those of IX and X in case 1 remained unchanged even after 6 months.
Since the occurrence of herpetic eruptions were especially noticeable along the area of the IXth and Xth cranial nerves, it was thus indicated that these cranial nerves were the main target of the infection in both cases. It thus appeared that the virus had spread to other cranial nerves via the communicating fibers.View full abstractDownload PDF (13090K) -

JOURNAL FREE ACCESSIn two cases, carcinoid tumors with primary foci in the middle ear were studied by transmission electron microscopy and the following results were obtained:
1. The tumor nests consisted of large sections with luminal structures, while both peninsular and insular parts made up several tumor cells in the thin sections. No mitotic figure were observed in any of the tumor nests.
2. The tumor cells were classified into 2 types consisting of cells with neurosecretory granules and cells without neurosecretory granules. The ratio of the former to the latter was 10 to 1. The latter were often seen among the insular parts of the tumor nests, while they has a big nucleocytoplasmic ratio, were scarcely present in the intracellular organelles other than the microfilaments and were similar to the basal cells of stratified squamous of pseudostratified columner ciliated epithelia.
3. In the insular parts of the tumor nests, irregular cell arrangement and an unequal nuclear size or obscurity/rupture of the basement membrane were all observed.View full abstractDownload PDF (32807K) -

JOURNAL FREE ACCESSWe investigated the morphological characteristics of the experimental facial nerve palsy induced by an interruption of the petrosal artery in guinea pigs, and evaluated the pathogenesis in order to clarify why severe palsy results in a delayed and incomplete recovery.
The results are as follows: 1) In general, the swelling of the facial nerve is most evident 3 days after the interruption, its degree being proportional to the grade of facial palsy. In animals with severe palsy, the ratios of the facial nerve relative to the facial canal (Fn/Fc ratios) were extremely high. This fact suggests that the facial nerve is thus extensively entrapped by the bony canal. The findings that no patent blood vessel was observed either in the perineurium or in the endoneurium also provide further evidence of entrapment. 2) In animals with severe palsy, axons and myelin sheaths became obviously irregular in shape and stained less strongly 3 days after the interruption. Severely damaged nerve fibers had still not recovered after 4 weeks when the Fn/Fc ratios had decreased to almost the same levels as those in the control's. The severe damage to the nerve due to its extensive entrapment in the bony canal thus seems to be the reason why the severe palsy results in a delayed and incomplete recovery.View full abstractDownload PDF (24471K) -

JOURNAL FREE ACCESSThe first case of allergic fungal sinusitis in Japan is herein reported which was diagnosed based on the findings of a histopathological examination. The patient was a 44-year-old male who had a nasal blockade of the left side. Mucosal thickening, focal areas of high attenuation on the maxillary sinus, and bony erosine of the sinus margin were revealed by CT. On histopathological examination, a number of eosinophils and Charcot-Leyden crystals were observed in the mucin obtained from the sinus. A few filamentous fungal elements were represented in a section of mucin stained with Grocott's method, but the mucosa of the sinus was not invaded by any fungi. The peripheral eosinophil count and specific IgE to any fungal antigens had both increased, and a skin test showed an immediate hypersensitivity response to fungus.
The allergic reaction against fungi, namely type I immune response, is thus considered to play an important role in the induction of disease, which is characterized by a non-invasive fungal proliferation.View full abstractDownload PDF (10734K) -

JOURNAL FREE ACCESSRemicut ® (emedastine difumarate) is a new anti-allergic agent which has been reported to produce a potent anti-histaminic activity. We evaluated the efficacy (especially, regarding the number of days required to show an improvement) of this agent taken 2 weeks by 38 patients (18 males and 20 females ) with perennial allergic rhinitis.
1) The final global improvement rate (either “improved” or better) was 64.0%.
2) The overall safety rate (“no side effects”) was 83.9%.
3) The global utility rate (“useful” or better) was 80.0%
4) Regarding the subjective symptoms, a high improvement rate of nasal obstruction (“improved” or better) was characteristic (58.3%)
5) The number of days required to show an improvement was as follows: sneezing-3.7 days, and sniveling-3.9 days, nasal obstruction-5.7 days.
6) Side effects consisting mainly of sleepiness occurred in 5 patients. No abnormal laboratory findings were observed.
These results thus indicate that emedastine difumarate is useful in treating perennial allergic rhinitis, especially in order to obtain an improvement in nasal obstruction symptoms.View full abstractDownload PDF (16246K) -

JOURNAL FREE ACCESSAn evaluation of the expression of the argyrophilic nucleolar organizer region (AgNOR) and the S-100 labeled was done in tissue specimens taken from 76 laryngeal carcinomas. The average number of AgNOR per nucleus (AgNOR number) was 4.30, and the AgNOR number of advanced tumors (stage III, IV) or N positive groups (N1, N2, N3) was statistically higher than the early stages ( I, II) or NO tumors. There was also a significant difference in the population density of the S-100 protein labeled cells between N3 and N0-N2 or between the M0 and M1 cases. A statistically significant difference in the survival rate was noted between the groups with a low, intermediate and high average of the AgNOR number. The population density of the S-100 protein labeled cells was statistically low in the patients with recurrence as compared to the cases without recurrence. These results thus indicate the prognostic significance of the AgNOR number and the S-100 labeled cells in laryngeal carcinomas.View full abstractDownload PDF (17295K) -
