OBJECTIVE We examined the relationship between intima-media thickness of common carotid artery (CCA-IMT) and silent cerebral infarction (SCI) with the magnetic resonance imaging (MRI) study in Japanese subjects with type 2 diabetes. RESEARCH DESIGN AND METHODS The brain MRI study and the carotid ultrasonography were performed in a total of 217 consecutive(More)
In order to estimate the risk of primary brain tumor (PBT), we attempted to estimate the national incidence rates of PBT by histological subtypes using the Brain Tumor Registry of Japan (BTR). The number of deaths due to PBT in a certain year is the sum of the deaths among patients diagnosed in different years. Registered cases in the BTR represent incident(More)
Sinus fungus ball is defined as noninvasive chronic fungal rhinosinusitis occurring in immunocompetent patients with regional characteristics. The clinical and imaging characteristics of paranasal sinus fungus ball were retrospectively investigated in 104 Japanese patients. All patients underwent endoscopic sinus surgery. Preoperative computed tomography(More)
Hypertrophic pachymeningitis is a rare disease, and the fibrosing inflammatory process causes a thickening of the dura mater. A 62-year-old male undergoing corticosteroid therapy for autoimmune pancreatitis presented with headache and right facial numbness. Brain CT and MRI revealed thickened mass lesion around the tentorium. The specimen obtained by biopsy(More)
Radiation-induced brain tumor is a rare but serious and potentially fatal complication. We report two cases of radiation-induced fibrosarcomas which occurred more than 20 years after whole brain radiation therapy (60 Gy) for intracranial germinomas. Although both of them underwent imaging examination every year, the symptomatic sarcomas developed rapidly(More)
OBJECTIVES To examine the relationship between speech intelligibilities among the similar level of hearing loss and threshold elevation of the auditory brainstem response (ABR). METHODS The relationship between maximum speech intelligibilities among similar levels of hearing loss and relative threshold elevation of the click-evoked ABR (ABR threshold -(More)
The anti-inflammatory effects of macrolides may be associated with a reduced frequency of exacerbation of chronic obstructive pulmonary disease (COPD). However, because the long-term use of antibiotics may promote the growth of drug-resistant bacteria, the development of a treatment to prevent COPD exacerbation with macrolides that do not exert(More)
Efinaconazole 10 % solution is a new triazole antifungal agent developed for the topical treatment of fungal infections of the nails. The current study examined the effect of intratympanic application of efinaconazole 10 % solution in the guinea pig ear. Sixteen male Hartley guinea pigs (weight 501-620 g) were divided into 3 groups to be treated with(More)
OBJECTIVES To describe objective tinnitus complicated with transient low-tone hearing loss coinciding with mouth opening, which was related to the connection between the mandibular fossa and middle ear space. PATIENTS A 41-year-old man presented with tinnitus, ear fullness, and hearing loss in the left ear on mouth opening. MAIN OUTCOME MEASURES(More)
BACKGROUND Epithelioid hemangioendothelioma (EHE) is a rare vascular tumor that frequently occurs in soft tissues. Patients suffer from local recurrence and remote metastasis because of its malignant potential. Here, we present a rare case of EHE that originated from nasal cavity and invaded intracranially through the anterior skull base. CASE DESCRIPTION(More)
