JOURNAL FREE ACCESSWe examined the blood flow in the pharyngeal mucous membrane of patients with abnormal sensation in the throat (AST) using a tissue spectrum analizer (TS-200, Sumitomo Elec.). Index Hemogrobin (IHb) was measured as an indicator of the blood flow by TS-200. First, IHbs measured at 11 different points in the pharynx and tongue were compared between patients with AST and control group. A number of patients with AST and that of control group were 32 and 28, respectively. Their mean ages were 49.0 and 30.7, respectively. There was significant decrease of the blood flow in the wide area of the throat in AST patients (p<0.05, t-test).
Next, we examined the relation between the blood flow and the fluctuation of the symptom. A total number of the AST patients was 57, the mean age was 51.4. Mean observation period for this study was 15 weeks. There was a strong correlation between the pharyngeal blood flow and the symptom. That is, the patients when their symptoms decreased showed significant increase of the blood flow in the pharynx especially at the point where they complained of abnormal sensation.
We cocluded that the decreased blood flow in the pharynx is one of important factors that caused the abnormal sensation in the throat.View full abstractDownload PDF (1044K) -

JOURNAL FREE ACCESSWe examined the differences of the autonomic pharyngeal responses to two kinds of stimuli between the patients with abnormal sensation in the throat (AST) and the control group.
The total number of AST patients were 38 (15 males and 23 females, mean age; 51.9 years old). The control subjects consisted of 24 (19 males and 5 females, mean age; 25.4 years old).
In the first experiment, 0.001% adrenalin was sprayed to the subject's pharyngeal wall. In the second experiment, the subjects were brought into the cold room (5°C) for 10 min. Before and after the giving the stresses, we measured Index Hemoglobin (IHb) as an indicator of the blood flow in the posterior oropharyngeal wall by a tissue spectrum analizer (TS-200, Sumitomo Elec.).
As a result, both stress experiments revealed that decreasing rates of pharyngeal blood flow (IHb) of the AST group were significantly smaller than those of the control group. The interpretation of the change in IHb is discussed.View full abstractDownload PDF (240K) -

JOURNAL FREE ACCESSThe prognosis of hypopharyngeal cancer is poor, because the majority of this cancer are of advanced stage at the first examination.
We studied the diagnostic process from initial symptoms of 38 patients with hypopharyngeal cancer at our clinic. The majority of patients (35 out of 38) were diagnosed as being advanced stage, therefore the early detection of the hypopharyngeal cancer was important. The case histories were reviewed retrospectively and the following results were obtained. First, careful observation and long term follow up of patients who complaint of abnormal sensations of the laryngopharynx is essential. Second, it is necessary to enlighten the physician, whose speciality is not bronchoesophagology, about the hypopharyngeal cancer and how to manage cervical nodal swellings. Finally, the physician should pay attention that there may be multiple primary lesions in the oral cavity, pharynx, larynx, and esophagus.View full abstractDownload PDF (354K) -

JOURNAL FREE ACCESSDuring the last 16 years, seven cases of denture foreign bodies in the esophagus were treated at the Third Department of Surgery, Nihon University, School of Medicine. Before coming to our hospital, all cases had been treated by endoscopy in other hospital or in other department unsuccessfully. In our seven cases, two dentures were removed by esophagotomy through the external neck inscision, three dentures required thoracotomy, and remaining two dentures were removed by gastrotomy.
In general, esophageal foreign bodies can be removed by endoscopy, but in some cases whose foreign bodies could not be removed by endoscopy or in which the perforation of esophageal wall is suspected, surgical removal should be necessary.View full abstractDownload PDF (2857K) -

JOURNAL FREE ACCESSIt has been already reported that; 1) critically ill patients have elevated levels of adenosine triphosphate (ATP) degradation products, 2) during acute alveolar hypoxia, there is a marked rise in adenosine, inosine, and hypoxanthine tissue levels and there appears to be a progressive degradation of ATP, and 3) following bronchial provocation with allergen, plasma levels of adenosine increase from a base line. However, measurement of the plasma adenosine levels and other nucleosides have not been reported for patients with lung diseases. To determine whether ATP degradation occurs in patients, we measured plasma levels of adenosine, guanosine, inosine, hypoxanthine, and xanthine in 46 patients with bronchial asthma, 4 patients with pulmonary emphysema, 44 patients with lung tuberculosis and seven control subjects. Patients with bronchial asthma had higher plasma levels of adenosine, guanosine, and xanthine than the control group. Patients with bronchial asthma in severe type had lower plasma levels of adenosine and guanosine than those in mild type. Our present study revealed elevated venous plasma levels of ATP degradation products in patients in comparison with control group. This elevation may reflect in part the presence of long disturbance of metabolism in patients.View full abstractDownload PDF (2536K) -

JOURNAL FREE ACCESSWe found that the nasal respiratory resistance in patients with nasal polyps began increasing at a certain threshold level of methacholine concentration (sensitivity) and it showed a curvilinear slope (reactivity). Thus, we were able to estimate hypersensitivity of the nasal and lower airway by the dose-response curve of nasal respiratory resistance by the continuous nasal inhalation of methacholine in stepwise incremental concentrations.
There have been two current theories on pathogenesis of nasal polyps: allergic and non-allergic. However, there are little data which elucidate the mechanism of polyp formation.
In this study, patients were classified into two groups according to clinical findings: an atopy group, and a non-atopy group. We studied the difference between these two groups concerning of the reaction site of methacholine inhalation.
The nasal airway responded in all patients. However the effect of methacholine on the lower airways in the non-atopy group was not remarkable.
This objective measurement seems to be useful in the estimation of severity of the nasal and/or lower airway hypersensitivity in the patients with nasal polyps.View full abstractDownload PDF (308K) -

JOURNAL FREE ACCESSMucoepidermoid carcinoma of the larynx is very rare and only five cases have been reported in the Japanese literatures. A case of mucoepidermoid carcinoma of the larynx which we recently experienced is reported and discussed with the review of the literatures.
The case is a 65-year-old man who was admitted to our hospital complaining of dyspnea. Laryngeal fiberscopy revealed a tumor in the subglottis. Excisional biopsy was done under direct laryngoscopy on January 18, 1990. Pathological report was compatible with mucoepidermoid carcinoma of high grade malignancy. The patient underwent radiotherapy at the dose of 65 Gy. In the course of treatment, two lymph nodes became palpable in the left supraclaviclar region. So, the radiation field was extended.
Then they disappeared soon, and radiotherapy was continued. He shows no evidence of local recurrence or regional metastasis to date.View full abstractDownload PDF (325K) -

JOURNAL FREE ACCESSAcase oo subglottic stenosis in a 55-year-old woman due to relapsing polychondritis is reported. She subsequently developed glottic and tracheal stenosis. The diagnosis was made aoter laryngeal biopsy. Subsequently, chondritis of the ear and arthritis also developed with immediate clinical improvement following steroid therapy.
Over 80 cases of relapsing pofychondritis have been reported in Japan. Similar to the other reports, ear chondritis is the most common symptom of this disease. Laryngeal involve ment was reported in 26 of these cases (30%), and was often manioested as an inflammation of the supraglottic and g1ottic spaces.
Chondritis in the respiratory organs often deve1ops in patients with relapsing polychon dritis, but subglottic stenosis is an unusual clinical feature. The present case is, as far as we know, the first report in the world literature.View full abstractDownload PDF (6032K) -

JOURNAL FREE ACCESSA case of fungal infection of the larynx is reported. The patient is a 75-year-old man with a chief complaint of aphonia. Laryngeal fiberscopy revealed thick white plaques covering the whole lumen of the larynx. Specimens for a pathological examination were taken from the plaque and its underlying tissues at the left false cord. Histopathologically, they consisted of a large quantity of pseudohyphae and blastopores and diagnosed as the infection of candida. Therapy was initiated with fluconazole (200 mg/day) for two weeks and the plaques of the larynx were disappeared completely. He has been followed-up without any recurrence to date. The fungal infection of the larynx is very rare and only 16 cases have been reported in the Japanese literature. We reviewed them with some discussions.View full abstractDownload PDF (2818K) -

JOURNAL FREE ACCESSLaryngeal web is a relatively rare disease. However its treatment has attracted the attention of laryngologists. We encountered a very severe case of recurrence of laryngeal web caused by the laryngofissure undergone 27 years ago. There are two surgical approaches for laryngeal web, i. e. direct laryngoscopy and laryngofissure. In the present case, laryngofissure was performed and an umbrella silicone keel was used to prevent readhesion. Although now a day, laryngofissure has been seldomly performed for the treatment of laryngeal web, it proved very effective to prevent the adhesion of the anterior glottis in the present case. A. silicone keel was specially made and used based on Montgomery's report. As far as postoperative voice quality is concerned, this technique is not satisfactory. However, it provides a favorable result with respect to airway patency without any postoperative granuration tissue or readhesion.View full abstractDownload PDF (507K) -

JOURNAL FREE ACCESSAn application of the CO2LASER under fiber optic guide to treat some laryngeal lesions is described. The device consists of a probe and a fiber optic bundle whose diameters are 2.3 and 6 mm, respectively. This assembly enables us to perform the CO2LASER surgery on the larynx under the guide of the fiber optics. Since there is no intubation tube for the general anaesthesia, it is easy to get a wide surgical field at the posterior part of the glottis. Subglottic lesions are also operable by this device inserted through the tracheal stoma.
Using this device, it becomes possible to operate on a patient who is of poor risk to get general anaesthesia and cannot be hospitalized.View full abstractDownload PDF (449K) -

JOURNAL FREE ACCESSWe performed image processings on pictures obtained from patients with esophageal diseases by using an electronic endoscope TV-Endoscope TGI-70D (Toshiba Co., Ltd.) and a digital endoscopic image processor EIP-70A (Toshiba Co., Ltd.).
By using the EIP-70A, it becomes possible to perform a band pass filtering as structural enhancement and a histogram flattening as color enhancement in real-time. The band pass filtering clarified the fine vascular pattern of the esophago-gastric junction, the fine regenerative mucosal pattern of the reflux esophagitis and the three-dimentional structure of the advanced esophageal cancer. The histogram flattening exaggerated the redness in lesions of the advanced esophageal cancer, the O-II b typed esophageal cancer and the ectopic gastric mucosa of the upper esophagus.View full abstractDownload PDF (3762K)
