JOURNAL FREE ACCESSTwo cases of muco-pyocele of the posterior nasal accessory sinuses were reported. The diagnostic procedure of the disease was considered with special reference to a clinical evaluation of "computed tomography". The following conclusions were drawn:
1) Muco-pyocele of the posterior nasal accessory sinuses is one of the most clinically significant disease causing visual disturbances. An early establishment of both diagnosis and surgical treatment is of prime importance for a satisfactory results.
2) Conventional ophthalmological examinations, plain sinus and skull films, tomograms of the region of the posterior nasal accessory sinuses and angiograms of the internal carotid artery and the orbital vessels may be useful for making differential diagnosis of that pathologic condition, though these may require considerable experiences.
3) The computed tomographic scanning (CT) is very valuable in the investigation of the posterior paranasal and the surrounding lesions, since the CT scan is capable of demonstrating whether these lesions are arising from, or extending into the posterior nasal accessory sinuses. The CT scan may be helpful to identify muco-pyocele and to differentiate it from many other diseases such as hypophyseal tumor or orbital lesions on the basis of detailed findings.View full abstractDownload PDF (1028K) -

JOURNAL FREE ACCESSImpedance audiometry by the otoadmittance meter was examined in more than 2000 patients consulted in Kitano Hospital during 1975 and 1978, One thousand and ninety two tympanograms in various otological diseases were analysed. The most high percentage of B and C type tympanograms was seen in patients with middle ear diseases, especially with adenoid vegetation. The lowest percentage of B and C type was seen in cases of tinnitus with normal audiograms and hyperacusis. In cases of sensori-neural deafness, complete deafness and sudden deafness, B and C types were observed in 34 to 56 percent of these patients. In cases of Bell's palsy and Hunt's disease, B and C types were seen in 20 to 31 percent of these patients. Thirty-Six percent of myasthenia gravis showed B and C types, and same percentage of B and C types was recorded from contralateral ears of middle ear disease patients.
In this report, additionally, the mean otoadmittance values in normal subjects were calculated and the values in various diseases were comparatively examined.View full abstractDownload PDF (643K) -

JOURNAL FREE ACCESSIn this paper statiscal analysis of eighteen hundreds and twenty-two cases of sensorineural hearing loss was performed.
Following results were obtained.
1. The incidence of the sensorineural hearing loss with unknown etiology was 52.3% of all patients with sensorineural hearing loss. Men were affected more frequently than women, in a ratio of 1.47:1.
2. The sensorineural hearing loss with unknown etiology was frequently observed in the aged group.
The bilateral hearing loss, which showed the same pattern in audiogram and gradual high tone hearing loss were frequently observed in the patients with sensorineural hearing loss with unknown etiology.
The clinical findings were more obvious with the aging.
3. The sensorineural hearing loss with unknown etiology was thought to include two different types, namely the type which was mainly observed in the young group and the other type which was observed in the aged group. The cause of two types was suspected to be different.
The sensorineural hearing loss with unknown etiology was considered to deeply related to aging.View full abstractDownload PDF (678K) -

JOURNAL FREE ACCESSExtent of infiltration was investigated by macro- and microscopic observations in 41 specimens of laryngeal cancers which were removed by the partial or total laryngectomy.
The following results were obtained:
1) In 41% of the specimens, cancers were found in the larngeal vestibule. In this region, laryngeal cancers was thought to develope from the metaplastic epithelium.
2) Cancers in laryngeal vestibule had a tendency to infiltrate into the preepiglottic space. The extent of this infiltration corresponded with the degree of retroflexion of the epiglottis and the extent of cervical lymphonodes metastasis. The decrease of mobility and the strong retroflexion of the epiglottis were thought to be important clinical signs in the anterior infiltration of this cancer.
3) The tumor, which infiltrated into the anterior commissure, showed inferior infiltration on perichondrium of the thyroid cartilage. However, infiltration in the mucous membrane of the larynx was not detected.
4) Pre-operative irradiation was effective to decrease the number of living tumor cells, but it was not effective to decrease the extent of infiltration.View full abstractDownload PDF (1074K) -

JOURNAL FREE ACCESSThe twenty-one patients with apple pollinosis in Aomori prefecture (Japan) were reported in this paper.
These patients (male: 7, female: 14) showed typical symptoms of allergic rhinitis (100%), conjunctivitis (100%), pharyngitis (38.1%), dermatitis (28.6%) and persistent cough (33.3%). These symptoms appeared at the flowering time of apple tree and was observed during the pollination work in the apple farm.
17 patients out of the 21 cases were farmers engaged in the apple pollination work for 7-25 years. Other 4 patients have lived near the apple farm. Thus, the contact with large amount of apple pollen was thought to be the cause of the sensitization. Generally speaking, these patients had severe nasal symptoms and eosinophilia in nasal secret, and showed high sensitivity to the apple pollen in the intradermal test and the provacation test to the nasal mucosa.
However, IgE value by RIST (mean value: 484u/ml) showed no seasonal change, and the value of IgE antibodies by RAST was lower than those of the other pollinosis, though it was determined as positive. The desensitization therapy with apple pollen antigen extract was effective.
From results of the questionnaire study to apple farmers in Aomori prefecture, 7.34% of the answerer (5240 cases) were suspected as apple pollinosis.View full abstractDownload PDF (773K) -
ANALYSIS OF THE HUMAN SKULL BONE VIBRATIONMASAMI MIKI1980 Volume 83 Issue 1 Pages 46-54

JOURNAL FREE ACCESSVibration of the human skull bone was observed by means of the holographic interferometry.Holography is a new optical technique which is originally being applied to the transmission and the management of the image-information. Holographic interferometry, an application of holographic technique, is an unique and useful method for analysis of vibration, in which the human skull bone vibration was analyzed three-dimensionally. Three human dry skull bones were used, and the results are as follows;
1) Number of the first proper vibration of the skull bones, whose sutures were filled with Alon alpha, ranged between 1700 and 2100Hz. The proper vibration numbers of the higher degrees were also observed.
2) At each proper vibration number, the skull bone vibrated greatly on the bilateral temporal regions and vibrated less on the median region. This mode was common on the other proper vibration numbers of the higher degrees. The distortion of the skull bone was estimated as about 10-7cm at 0dB.
3) It is known that the inertia bone conduction acts a great part on the low frequency. Through this research, however, the possibility of the compressive bone conduction was considered even in the low frequencies.View full abstractDownload PDF (824K) -

JOURNAL FREE ACCESSThe fine structure of crypt epithelium in human palatine tonsils was studied by scanning electron microscopy (SEM).
The tonsils were obtained from patients with chronic tonsillar infection. Immediately following tonsillectomy, the tonsils were puncture-perfused with glutaraldehyde fixatives. By this procedure, blood and tissue fluid were eliminated from the tissues. Specimens were freezecracked and the inside structure of the epithelium was exposed for examination by SEM.
Crypt epithelium was classified into three types according to the three-dimensional structure. Type I epithelium: It was stratified squamous epithelium. In the basal and intermediate layers, intercellular space of the epithelial cells formed a network of canalicules, which were considered as passages for infiltrating cells.
Type II epithelium: Epithelial cells were polygonal in appearance and possessed several cytoplasmic processes, by which they were connected with each other to form a meshwork in this epithelium. A large number of infiltrating cells were observed in the meshes of the epithelial cells, showing the state of "lympho-epithelial symbiosis". There were "cryptal micropores" in the surface layer, and they communicated the cryptal lumen to the network structure of the epithelium. It was suggested that the cryptal micropores might represent passages for infiltrating cells and various antigens.
Type III epithelium: This epithelium showed a destruction of the superficial layer and marked cell infiltration. There were a lot of collagen fibers, several blood vessels and a few squamous epithelial cells in the epithelium. It was suggested that the construction of this epithelium was caused by chronic inflammation.
Based on these results, it revealed that the type II epithelium was playing an important role in the immunological activity of the tonsil.View full abstractDownload PDF (3166K) -

JOURNAL FREE ACCESSComputed tomography (CT) of the thyroid gland was performed with computed tomograph (GE CT/T). The photographed images were compaired with the findings of the surgical operations. The conclusions were as follows:
The thyroid gland was seen as high density area in CT figure. Some important parameters such as size, shape and position of the tumor could be identified on the CT films. The CT was found to be useful for differentiating cystic lesions from solid tumors. It was difficult to discriminate, however, benign tumors from malignant ones.
The size of the thyroid gland with Graves' disease was measured on the CT films in order to determine a proper guide for the surgical removal. Further, it was pointed out that a more detailed information might be obtained by an advanced graphic data processing.View full abstractDownload PDF (827K)
