Hyalinizing clear cell carcinoma is a low-grade indolent and rare salivary gland tumor originally described by Milchgrub et al. in 1994. We herein report a case of this tumor of the base of the tongue. A 66-year-old Japanese woman presented with a large painless mass in the throat. Computed tomography and magnetic resonance imaging revealed a 40x30-mm(More)
BACKGROUND There has been a growing awareness that nasal obstruction may impair various daily and social activities. We performed a questionnaire survey in a working population to clarify the contribution made by snoring concomitant with nasal obstruction to daytime sleepiness and quality of life (QOL). METHODS Seven thousand nine hundred eighty daytime(More)
In our controlled retrospective analysis of medical records in tertiary care academic medical center, we aimed to investigate the therapeutic effects of hyperbaric oxygen (HBO) therapy combined with steroid administration for idiopathic sudden sensorineural hearing loss (ISSNHL) in comparison with that of steroid administration alone. Our subjects were 130(More)
Dark-skinned people are known to be more tolerant of ototraumatic noise than are light-skinned people, and pigmented animals are more tolerant of ototraumatic noise and aminoglycoside ototoxicity than are albino animals. Such tolerance may be dependent on the local ability of detoxification and antioxidant enzymes, including glutathione S-transferase (GST)(More)
OBJECTIVES There has been growing awareness that nasal obstruction may impair various daily and social activities. We performed a questionnaire survey on a working population to clarify the relationships among nasal obstruction, daytime sleepiness, and quality of life (QOL). METHODS Seven thousand nine hundred eighty daytime workers were asked to complete(More)
OBJECTIVE We conducted a controlled retrospective analysis of patients with idiopathic sudden sensorineural hearing loss (ISSNHL) in order to investigate the effect of prostaglandin E1 (PGE1) plus hyperbaric oxygen (HBO) therapy in comparison with that of steroid plus HBO therapy. METHODS One hundred and ninety-six consecutive patients with ISSNHL(More)
Dominant white spotting W/W(v) and W(v)/W(v) mice are well-known mutants that lack strial intermediate cells in their cochlea and manifest hereditary sensorineural hearing loss. We recently reported marked thickening of and IgG deposition on the basement membrane of strial capillaries in W/W(v) mutant mice, similar to observations made in aged animals and(More)
BACKGROUND Eikenella corrodens (E. corrodens) is a Gram-negative facultative anaerobic bacillus that originally was thought to be an attenuated and indigenous bacterium. In recent years, a number of reports have documented that E. corrodens can be a potential pathogen not only in immunocompromised patients but also in hosts with normal immunity. We herein(More)
CONCLUSIONS The risk factors for methicillin-resistant Staphylococcus aureus (MRSA) detection in head and neck cancer patients are the duration of hospitalization, intravenous hyperalimentation, prior antibiotic use, and the coexistence of other pathogens. OBJECTIVES To shed light on the clinical characteristics of MRSA-positive inpatients with head and(More)
CONCLUSIONS Prostaglandin E1 (PGE1) is less effective than stellate ganglion block (SGB) in the treatment of idiopathic sudden sensorineural hearing loss (ISSNHL) patients with severe hearing losses when used together with hyperbaric oxygen (HBO) therapy. In contrast with the systemic action of intravenous PGE1, SGB's localized vasodilating action may(More)
