Synovitis, which is characterized by the infiltration of inflammatory cells, often accompanies progression of temporomandibular joint disorder (TMD) symptoms. Because IL-1β is elevated in synovial fluids obtained from TMDs, we hypothesized that IL-1β-responsive genes in synoviocytes may help identify the putative genes associated with synovitis.

The purpose of this study was to determine the clinicopathological and immunohistochemical features of lipoma/fibrolipoma with rare occasions as osseous and/or chondroid differentiation in the oral cavity. Two cases of the tumors, who presented with a painless, relatively hard mass on the oral mucosa, were studied. These were consisted of a(More)
BACKGROUND In this study, we analyzed the gene expression profile of fibroblast-like synoviocyte (FLS) cultures from the temporomandibular joint (TMJ) to identify candidate genes associated with intracapsular pathologic conditions of TMJ. Cyclooxygenase (COX)-2 was one of the genes in FLS upregulated following stimulation by interleukin (IL)-1beta, a(More)
We report a rare case of acinic cell carcinoma of the palate in a 63-year-old Japanese woman. Clinical examination demonstrated a firm, mobile mass without regional lymph-adenopathy. Histopathologically, the tumor was composed of large, polyhedral or round cells with basophilic granular cytoplasm (serous acinar-like cells) and reticular or clear cytoplasmic(More)
OBJECTIVE To evaluate the usefulness of exfoliative cytology as a diagnostic tool for patients with clinical symptoms of desquamative gingivitis. METHOD AND MATERIALS Fifteen patients clinically diagnosed with desquamative gingivitis were evaluated. At their first visit, a cytologic smear was performed on the gingival lesion. On their second visit, a(More)
Pemphigus Vulgaris (PV) is an autoimmune intraepithelial blistering disease involving the skin and mucous membranes. Oral mucosa is frequently affected in patients with PV, and oral lesions may be the first sign of the disease in majority of patients. In some patients, oral lesions may also be followed by skin involvement. Therefore, timely recognition and(More)
BACKGROUND Pemphigus vulgaris (PV) is an autoimmune disease characterized by acantholysis in the epithelium. PV is often difficult to diagnose in the early stages, since the oral lesions are relatively nonspecific. We report on a case with a favorable outcome due to early diagnosis and effective treatment of oral lesions. METHODS A 53-year-old Japanese(More)
BACKGROUND Pemphigus vulgaris (PV) frequently begins with oral lesions and progresses to skin lesions. A patient is described who developed skin lesions during follow-up and whose only initial symptom was desquamative gingivitis (DG). METHODS A 31-year-old woman presented with a 2-month history of painful gingiva. The diagnosis of PV was made according to(More)
In recent years, the use of mouthwash has become widespread as a part of routine oral hygiene. However, there have been no fundamental studies on the influence of mouthwashes on the human oral mucosae. One hundred and twenty-five subjects (50 males and 75 females) were selected for this study. The effects of mouthwash was assessed with the use of(More)
A rare case of myoepithelioma of the buccal gland in a 54-year-old Japanese woman is reported. As the swelling exhibited a normal mucosal color and was relatively well defined, showing no ulcers, a benign salivary gland tumor was suspected upon clinical inspection. Microscopically, the parenchyma of the present case mainly consisted of plasmacytoid cells(More)
