JOURNAL FREE ACCESSTympanosclerosis was investigated clinically in 74 initial surgical cases 25 males and 49 females who were operated on between 1984 and 1999. Hearing improvement after the tympanoplasty was measured according to the new standards proposed by the Otological Society of Japan in 1999. These results were then compared to those arrived at using the old standards for measuring hearing improvement. Hearing improved according to both standards in 71.6% of the cases. However, the overall success rate fell by 10% according to the new standards. The characteristics of the unsuccessful cases were examined, and the general concept of tympanosclerosis was reconsidered. Many of the unsuccessful cases involved sclerotic lesions in the area surroundings the stapes and oval window. The most important factor preventing hearing improvement was the degree to which stapes movement was inhibited. In cases where the movement of the stapes is poor, an immediate stapedectomy is not advised because of the increased risk of internal ear infection. Instead, the stapedectomy should be performed after the inflammation disappears.View full abstractDownload PDF (821K) -

JOURNAL FREE ACCESSThe Science and Technology Agency gave us an opportunity to perform a general study on the factors that have led to an increase in the prevalence of Japanese cedar pollinosis. We conducted an epidemiological study using the MAST-26 system in the town of Minabe, Hidaka county, Wakayama prefecture. The results were as follows :
1. The positive ratio for subjects with specific IgE antibodies against Japanese cedar pollen was 50.6% using the MAST-26 system. The positive ratio for other allergens, such as timothy, D. farinae, and sweet vernal, was 23.8%, 14.5%, and 11.9%, respectively. The positive ratio for food allergens was 2.5% for soybeans and 11.9% for crab.
2. Sensitized cases with multiple allergens occurred in a large proportion of the subjects.
3. Specific IgE antibodies were found in all subjects with pollinosis symptoms.
4. Of the population with specific IgE antibodies, for cedar, 71.6% developed pollinosis symptoms.
5. The correlation between the MAST-26 system and the CAP system for specific IgE antibodies against cedar pollen was high ; the negative concordance rate was 96.2%, the positive concordance rate was 98.8%, and the overall concordance rate was 97.5%.View full abstractDownload PDF (879K) -

JOURNAL FREE ACCESSWe classified 1We classified 13 cases of laryngeal edema and/or abcess with dyspnea seen by our department between September 1998 and January 1999 into 3 types based on the site of swelling in the larynx and examined the relation ship between dyspnea and the site. Dyspnea rarely appears where only the epiglottis is swollen, but usually appears where both arytenoids are swollen.
Of our 13 subjects, 10 were treated successfully with intravenous antibiotics and steroids alone. The remaining 3 had epiglottic abcess requiring decompression drainage with laryngofiberscopy. We found such decompression to be safe, easy, and effective.View full abstractDownload PDF (913K) -

JOURNAL FREE ACCESSTo evaluate the efficacy of intraoperative ultrasonography in diagnosing thyroid tumors, we studied 32 cases (4 men and 28 women) with multinodular thyroid and suspected thyroid malignancy seen at our iustitute from 1998 to 2000. Equipment included a Hitachi echopal ultrasound diagnostic system with a 10 MHz frequency and a 38 mm wide probe. To detect superficial tumor, intermediate jelly must be applied appropriately to the probe, which is then brought into contact with the exposed thyroid surface. We concluded that surgeons would benefit much from intraoperative thyroid ultrasonography in direct real-time confirmation of tumor sites and properly determine the extent of resection required. Intraoperative thyroid ultrasonography is also very useful in detecting occult cancer when clinical examination indicates only lymphatic metastasis.View full abstractDownload PDF (1012K) -

JOURNAL FREE ACCESSWe report a rare case of lymphoepithelioma in the subaural region. The patient was a 42-year-old male complaining of a swelling in the left subaural region. Clinical examination revealed a firm nodule measuring 50 x 37 mm. MRI findings revealed a tumor with defined margins in the left subaural region. The tumor was sharply demarcated from the parotid gland. A fine needle aspiration was perfomed, and the cytologic diagnosis was adenocarcinoma. The tumor was removed under a general anesthesia. The surgical findings revealed that the tumor had developed from the parotid gland, and the histological diagnosis was lymphoepithelioma. The cytologic diagnosis and the histological diagnosis thus differed. Lymphoepithelioma is usually distinguishable from well-differentiated adenocarcinoma but is difficult to distinguish from poorly differentiated adenocarcinoma. Our results suggest that lymphoepithelioma may be undiagnosable when it occurs in a rare region. However, distinguishing between lymphoepithelioma and adenocarcinoma is important for optimal treatment.View full abstractDownload PDF (1761K) -
