We present a retrospective study of 82 patients with intraoral minor salivary gland tumors which were diagnosed from 1979 to 2003 in Gifu University Hospital. The histological diagnoses were reevaluated according to the 1991 WHO classification. A total of 82 tumors, consisting of 55 benign and 27 malignant tumors, were found in 28 male and 54 female(More)
In order to define and map chromosomal copy number alterations in salivary gland tumors (SGTs), a comparative genomic hybridization (CGH) technique was applied to two pleomorphic adenomas (PAs), one adenoid cystic carcinoma (ACC), and one basal cell adenocarcinoma (BCAC). The PAs exhibited regional copy number losses at 5q12.4-q14.1, 9q12-q21.13, and(More)
PURPOSE To evaluate the usefulness of diffusion-weighted MR imaging using a transient gustatory stimulation method in patients with xerostomia. MATERIALS AND METHODS Ten consecutive patients complaining of xerostomia and 10 healthy volunteers were examined with a 1.5 Tesla (T) MR unit. All study subjects completed a questionnaire, and patients underwent(More)
Kabuki make-up syndrome (Niikawa-Kuroki syndrome), recognized in Japan in 1981, is characterized by mental and growth retardation with specific craniofacial malformation such as lower palpebral eversion and depressed nasal tip. In this paper we describe a case associated with cleft lip and palate. Attention should be paid by maxillofacial surgeons to this(More)
This report presents a mortality study among the 17,344 members of the Construction Workers' Health Insurance Society of Mie Prefecture in Japan. The study period was between 1973 and 1993. During this period, 480 members died. Age-specific mortality rates of Mie Prefecture were used as comparison standards. Significantly elevated standardized mortality(More)
Several genetic alterations have been reported to contribute to the development of oral squamous cell carcinoma (OSCC). Recent studies have shown roles of promoter hypermethylation of tumor suppressor genes, including p16 and MGMT, in several types of cancers. The purpose of this study is to examine the hypermethylation status of p16 and MGMT genes in both(More)

The so-called calcifying odontogenic cyst (COC) shows extensive diversity in its clinico-histopathological appearances and biological behaviour. Because of this diversity, there has been confusion and disagreement on the terminology and classification of this lesion. The attempts at classification of COC may be divided into two concepts. The first concept(More)
The distribution of subunit A of blood coagulation factor XIII (FXIIIa) was investigated by the avidin-biotin-peroxidase complex (ABC) method in various oral and maxillofacial tissues. These tissues were from normal tongue, gingiva, lip, and submandibular gland, and from Dilantin gingival hyperplasia (one case), pyogenic granuloma (three cases), peripheral(More)
