JOURNAL FREE ACCESSOne hundred and twelve patients (203 ears) who underwent DPOAE (distortion-product otoacoustic emission) test, SISI (short increment sensitivity index) test and MCL/UCL (most comfortable loudness level / uncomfortable loudness level) test were analyzed. The positive rates of the DPOAE test at 1 kHz and 4 kHz were 41%and 69%, respectively. The positive rates of the SISI test at 1 kHz and 4 kHz were 20%and 53%, respectively. The positive rates of the MCL/UCL test at 1 kHz and 4 kHz were 43% and 54%, respectively. The positive rate of these three examinations were evaluated and correlated with the hearing level. DPOAE, SISI and MCL/UCL showed a positive rate from around 20 dB. The positive rate for DPOAE demonstrated a sharp increase and reached 90% around 35 dB, whereas those for SISI and MCL/UCL showed a gradual increase and reached 90% around 55 dB.View full abstractDownload PDF (824K) -

JOURNAL FREE ACCESSA case of laryngeal keratosis is herein reviewed. The macroscopic findings improved after treatment. The voice quality also improved after medical treatment. However, the patient was strongly advised to quit smoking in order to maintain the improved voice quality. The possibility of malignancy was evaluated in the initial diagnosis by stroboscopy, but, a complete pathological examination was required to rule out any possibility of malignancy.View full abstractDownload PDF (664K) -

JOURNAL FREE ACCESSNarrow Band Imaging (NBI) is a light source device developed by Olympus Medical Systems Corporation. It provides an optical highlighting technique whereby the capillaries and fine structures of the superficial mucosal layer are highlighted by confining the light supplied from the light source to specific wavelengths (415 nm and 540 nm) readily absorbed by hemoglobin in blood, unlike endoscopy with a conventional light source. This technique has been applied to differential diagnosis of malignant tumors of the gastrointestinal tract and its efficacy has been documented in an increasing number of reports. The present series was investigated by NBI for blood circulation reconstruction after surgery for chronic otitis media. The results showed that tympanic blood circulation underwent reconstruction progressing from the posterosuperior margin downward, beginning 2 weeks after the procedure.View full abstractDownload PDF (2050K) -

JOURNAL FREE ACCESSMeniere's disease patients often present with otalgia. However, doctors are often unable to listen to all of the patient's symptoms within the time allotted to attend to daily outpatient clinic visits. Consequently, otalgia has not yet been intensively investigated. This study attempted to investigate the clinical characteristics of otalgia in Meniere's disease patients. From February 2008 to June 2008, web-based questionnaires were administered and 59 patients answered. The results showed that otalgia was often accompanied by tinnitus or ear fullness. Otalgia frequency ranges from once everyday to once a week. The duration ranges between seconds and hours. With respect to the diagnosis and treatment of otalgia in Meniere's disease, many patients did not complain of otalgia to doctors. Some doctors understand and listen to the symptoms ; however, there have been no reports of patients who received intensive care for otalgia. Approximately 30% of the patients suffered from Meniere's disease and migraines or headaches, indicating close association between otalgia and migraines. There may be a common neural pathway leading to migraines that is associated with otalgia. The presence of a neural mechanism similar to the model explained in the trigeminovascular system theory may be associated with the glossopharyngeal nerve innervating the ear. Another possibility is that the sensory and somatosensory neuron cross-modality that is related to the sensation of ear fullness may somehow be associated with such otalgia cases. The limitation of this study is that the diagnosis of Meniere's disease is uncertain, since the enquiries were performed on the web and the diagnosis of Meniere's disease was not clearly confirmed. This patient group may suffer from Meniere's disease and anxiety disorder, depression, migraine-related dizziness and other forms of dizziness. This symptom may therefore be valuable to investigate new diagnostic and treatment strategies for Meniere's disease patients.View full abstractDownload PDF (532K) -

JOURNAL FREE ACCESSA solitary fibrous tumor is a rare neoplasm that typically arises in the pleura, but recently the tumor has been reported to also occur in other areas. A 59-year-old female with a tumor in the nasal cavity presented with the chief complaint of nasal swelling. CT revealed the tumor to occupy the right nasal cavity. A total resection was achieved through an extended Denker's operation. The histopathological diagnosis was a solitary fibrous tumor. The tumor cells were immunohistochemically positive for CD34. After the operation, there was no evidence of recurrence for 12 months.View full abstractDownload PDF (1452K) -

JOURNAL FREE ACCESSThis report documents a case of clear cell carcinoma of the tongue base,which is rare. The patient was a 56-year-old male. The tumor was detected by esohago-gastro-duodeno scopy. FDG-PET was negative in this patient. He underwent surgical therapy. The pathological diagnosis was clear cell carcinoma. There are rare cases of local recurrence and distant metastases with this type of tumor. The 10-year survival rates is about 90%. Treatment typically involves a wide surgical resection with or without lymph node dissection. Radiation therapy is administered for recurrent lesions or those with lymph node metastases.There are few reports describing the features of this type of tumor, therefore it is recommended that this patient should be observed with a long term follow-up.View full abstractDownload PDF (2855K)
