JOURNAL FREE ACCESSEleven cases of large vocal fold polyp were successfully treated with laryngomicrosurgical technique by using a side-opened direct laryngoscope and snare. Postoperative analysis revealed that excellent voice restoration was obtained in all cases. It is thought that an excess removal of the mucous membrane and much bleeding can be avoided by using a snare. When used in cases of laryngomicrosurgery in which bimanual manipulation of a snare and forceps was required, the manipulability of both hands in a side-opened direct laryngoscope was superior to that in a direct laryngoscope with a completely tubular shape.
In this paper, the method was demonstrated with a clinical case presentation and discussed from the viewpoint of the flexibility of the vocal fold mucous membrane and surgical manipulations which may influence on postoperative results.View full abstractDownload PDF (2940K) -

JOURNAL FREE ACCESSLight microscopic study of nerve endings in the human interarytenoid muscle was carried out by using the Baker's silver impregnated materials.
In addition to the ordinary motor nerve endings, there were three types of nerve endings surrounding the muscle fibers in an annular or helical manner.
The first type of the ending was composed of a thick myelinated fiber which tightly encircled and wrapped the muscle fibers. Branches from the myelinated fibers sporadically formed end buttons and loops. This type was determind as the spiral nerve ending.
The second type of the ending had several muscle fibers possessing both the spiral nerve ending and motor nerve ending. This type of the ending was considered to be the muscle spindle.
The third type of the ending was composed of both the spiral ending and motor nerve ending, which were thought to be either the nerve ending of the mixed type or the motor ending of the diffuse type.
These were the additional findings to our first report that revealed the presence of muscle spindles in the intrinsic laryngeal muscles. A similar system has been found only in the outer ocular muscles.View full abstractDownload PDF (4609K) -

JOURNAL FREE ACCESSSixteen cases of chronic eosinophilic pneumonia (CEP) were subjected to analyse the usefulness of transbronchial lung biopsy (TBLB) in the diagnosis of this disease. The eosinophil count in peripheral blood was 4311/p1 on the average at the first visit. Eight patients received TBLB prior to the corticosteroid therapy revealed the eosinophil infiltration in lung tissues. TBLB was performed within 9 days after corticosteroid administration in 4 cases, and eosinophil infiltration was observed in 3 cases. Remaining 4 cases received TBLB more than 9 days after initiation of corticosteroid therapy showed no eosinophil infiltration in lung tissues. However, eosinophil infiltration was observed in patients whose chest X-ray film showed an abnormal shadow.
Eosinophil count in bronchoalveolar fluid was consistent with histological findings.
These results indicate that TBLB should be performed to diagnose CEP before the administration of corticosteroid and to confirm histopathologically the lesions when the abnormal shadow was still present in the chest X-ray film after the steroid therapy.View full abstractDownload PDF (4223K) -

JOURNAL FREE ACCESSMorphology of the rabbit tracheal epithelial cells cultured on attached collagen gel (AG) and floating collagen gel (FG) was studied in comparison. Dispersed epithelial cells with 0.5%protease (26.5 units/ml) were seeded on the both collagen gels (0.4%) at a density of 2×105cells/ml/dish. They were cultured in Waymouth MB 752/1 medium supplemented with insulin (5μg/ml), hydrocortisone (0.1 μg/ml), epidermal growth factor (10 ng/ml) and fetal bovine serum (0.3%). After 6 days in culture, the cells on FG became cuboidal in shape, while the cells on AG showed flattened profiles. The intracellular features of the cells, such as Golgi apparatus, mitochondria, rough endoplasmic reticulum, lysosomes, etc., cultured with both methods were similar. By the 13th day, the cells cultured on AG remained flattened and Golgi apparatus was poorly developed. In contrast, the cells on FG became columnar and showed morphological features reminiscent of tracheal epithelium in vivo. These columnar cells had numerous microvilli and junctional complexes (tight junction, intermediate junction and desmosome) at their medium-facing surface and contained well developed Golgi apparatus. These findings are characteristic of a secretory cell. In the histocytochemical observation for thiamine pyrophosphatase (TPPase) which is one of the marker enzymes for Golgi apparatus, a reaction product was demonstrated in one or two trans Golgi cisternae of the cells cultured on FG during cultivating period. On the contrary, the cells cultured on AG have lost TPPase activity by the 13 day in culture.View full abstractDownload PDF (1757K) -

JOURNAL FREE ACCESSFour patients with esophageal or hypopharyngeal perforation caused by endoscopy treated from 1981 through 1989 at Kurume University Hospital, are reviewed.
1) All the patients were adult, two were male and two were female.
2) The cause was by flexible fiberscopy in two patients with hypopharyngeal perforation, by rigid esophagoscopy in two patients with esophageal perforation. The lesion of hypopharyngeal perforation was left piriform sinus and that of esophagus was entrance of cervical esophagus.
3) All the patients were treated surgically. Primary suture of the peforation was done in one case.
4) All the patients were cured.
5) The most useful examination was a lateral view of the cervical X-ray.
6) From our experience, the following treatment is recommended. Operation should be done as soon as possible, and primary suture of the perforation would be done if possible. The operative wound should be opened, and oral administration of foods would be started if possible. And the operative wound could be successively closed if there were no problems.View full abstractDownload PDF (5289K) -

JOURNAL FREE ACCESSIn order to confirm that the total esophagectomy without thoracotomy (blunt dissection) is, the good indication for hypopharyngeal and cervico-esophageal cancer, this malignancy was clinico-pathologically investigated. (Patients and Methods): In 25 patients with hypopharyngeal, cervico-esophageal and laryngeal cancer, blunt dissection was performed at our hospital between 1983 and 1988. The clinical data of these cases were reviewed to examine the morbidity and mortality of this operative procedure. The resected specimens of seventeen patients with squamous cell carcinoma of hypopharynx or cervical esophagus being received total esophagectomy were stained with Lugol's solution and totally sliced transversely after formalin-fixation. All the slices were histologically examined. (Results): The mean volume of the operative bleeding was 900 ml. The post-operative complications were relatively rare and not serious. Only one case died within 30 days after the operation. Another cancerous lesions were pathologically detected in thoraco-abdominal esophagi in 8 cases (47%). Atypical epithelia were histologically found out apart from main tumors in 13 cases (76%); severe dysplasia, 5 cases (29%), moderate, 6 (35%) and mild, 1 (6%). Twelve cases (71%) among them were complicated with multiple cancer or severe dysplasia. On the other hand, in all the female patients, another cancerous or dysplastic change was not seen. (Conclusion): Blunt dissection was considered to be the safe operative procedure, with rare serious complications and low mortality rate. Carcinoma of the hypopharynx and cervical esophagus was frequently complicated with another cancerous or severe dysplastic lesions in the thoraco-abdominal esophagus particularly in the male patients. Total esophagectomy was necessary for these cases to improve the prognosis.View full abstractDownload PDF (946K) -

JOURNAL FREE ACCESSWe reported a case of invasive laryngeal carcinoma arising in preexisting big laryngeal papillomatosis.
A-59-year-old man complained of increasing hoarseness and dyspnea before tracheotomy. We noticed huge tumor in the larynx. Pathological diagnosis was papilloma at the first examination. Because of recurrence of the tumor, frequent management by dioxide laser surgery was required to maintain an adequate airway every 2-month. At the fourth time biopsy, the histological diagnosis was epidermoid carcinoma. Papilloma virus was also found in carcinoma. For radical treatment, total laryngectomy was done, and his clinical course is very good for two years after surgery.
Some discussions were made concerning the classification, etiology, transformation into carcinoma and treatment of papilloma.View full abstractDownload PDF (1068K) -

JOURNAL FREE ACCESSA one-year-old girl and a two-year-old boy had accidentally aspirated a piece of peanut and takoyaki respectively. They were found accompanied with granulation tissues several months after the episode. Until then, those foreign bodies have caused severe pulmonary complications such an pneumonia, atelectasis and emphysema. Therefore, it was important to check the past history in detail to make a correct diagnosis of the original disease. The authors reviewed 54 reported cases with bronchial granulation due to foreign bodies from Japanese literature and discussed them briefly.View full abstractDownload PDF (935K) -

JOURNAL FREE ACCESSA 32-year-old male patient was admitted to our hospital with complaints of snoring and excess of daytime sleepiness. On the basis of overnight polysomnographic study, this patient was diagnosed as obstructive sleep apnea syndrome (OSA). Right heart catheterization revealed a slight elevation of mean pulmonary arterial pressure (24 torr) on admisson.
Nasal CPAP therapy during sleep was started without discomfort and was continued for 3 weeks. During the course of nasal CPAP therapy, apnea index reduced from 59.2/hour to 1.3/hour and his complaints improved significantly. After 3 weeks therapy, day time PaO2 at rest markedly increased from 66.9 torr to 87.6 torr and mean pulmonary arterial pressure reduced from 24 torr to 18 torr. We may conclude that the nasal CPAP is an effective and non-invasive tool for the treatment of OSA.View full abstractDownload PDF (887K) -
