The technique of tissue engineering is developing for the restoration of lost tissues. This new technique requires cells that fabricate tissue. Mesenchymal stem cells in bone marrow have been used as the cell source for this technique; however, dental pulp cells have recently been shown to possess stem-cell-like properties. We earlier demonstrated that(More)
The osteo-odonto-keratoprosthesis (OOKP), although described over 40 years ago, remains the keratoprosthesis of choice for end-stage corneal blindness not amenable to penetrating keratoplasty. It is particularly resilient to a hostile environment such as the dry keratinized eye resulting from severe Stevens-Johnson syndrome, ocular cicatricial pemphigoid,(More)
a o The prevalence of bisphosphonate-related osteonecrosis of the jaw (BRONJ) has recently increased, and this condition is difficult to manage. A patient is diagnosed with BRONJ if the following 3 characteristics are present: 1) current or previous treatment with a bisphosphonate (BP), 2) exposed bone in the maxillofacial region that has persisted for more(More)
It is difficult to treat severe Stevens-Johnson syndrome (SJS) patients with completely dry ocular surfaces, even using corneal transplantation with amniotic membrane and limbal grafts. For such cases, osteo-odontokeratoprosthesis (OOKP), which was first described by Strampelli, and Falcinelli et al., is a useful method for visual rehabilitation. We believe(More)
In the present study, we compared the incidence and severity of oral mucositis among patients undergoing allogeneic hematopoietic stem cell transplantation after fludarabine-based regimens with busulfan 12.8 mg/kg (FB12.8), with busulfan less than or equal to 9.6 mg/kg (FB9.6), and with melphalan 140 mg/m2 (FM). The incidence of oral mucositis after FB12.8(More)
Oral cancer in patients with mental retardation has not been reported in detail, although the literature on clinical management of oral malignancies in the general population is extensive. No clear consensus has been established regarding the management of oral cancer in patients with mental retardation. We present herein the case of a 32-year-old Japanese(More)
We report a patient with syringobulbia extending to the pons, who could not open his mouth widely. He had been involved in the traffic accident at 16 years of age. Since them he had suffered numbness in the left neck and arm. At age 30, he became unable to open the mouth widely with pain in the left jaw joint. He also noted dysphagia and tinnitus.(More)
Sodium channels play multiple roles in the formation of neural membrane properties in mesencephalic trigeminal (Mes V) neurons and in other neural systems. Mes V neurons exhibit conditional robust high-frequency spike discharges. As previously reported, resurgent and persistent sodium currents (INaR and INaP , respectively) may carry small currents at(More)
