Review Case ReportsPhosphaturic mesenchymal tumor, mixed connective tissue variant, of the mandible: report of a case and review of the literature.
Tumor-induced osteomalacia (TIO) is a rare paraneoplastic syndrome that results in renal phosphate wasting with hypophosphatemia. In most cases, the underlying cause of TIO is a small mesenchymal neoplasm that is often difficult to detect, resulting in delayed diagnosis. ⋯ We describe a PMTMCT involving the mandible in a patient with a protracted history of osteomalacia. A review of the current literature is provided with emphasis on the clinical and histologic features, etiopathogenesis, and management of PMTMCT in the setting of TIO.

Case ReportsThree-dimensional model simulation and reconstruction of composite total maxillectomy defects with fibula osteomyocutaneous flap flow-through from radial forearm flap.
A total maxillectomy always causes composite defects of maxilla, zygomatic bone, orbital floor or rim, and palatal and nasal mucosa lining. This leads to significant functional and cosmetic consequences after ablative surgery. The purpose of this clinical study was to preliminarily 3-dimensionally reconstruct the defect of total maxillectomy with sufficient bone support and soft tissue lining. ⋯ This preliminarily clinical study and case demonstrated that: the fibula osteomyocutaneous flap is an ideal donor site in 3D total maxillectomy defect reconstruction, because of its thickness, length, and bone uniformity which makes ideal support for dental rehabilitation; the flow-through forearm radial flap not only serves as the vascular bridge to midface reconstruction, but also provides sufficient soft tissue cover for the intraoral defect; and the 3D model simulation and preoperative surgical planning are effective methods to refine reconstruction surgery, shorten the surgical time, and predict the outcome after operation.

Randomized Controlled TrialTreatment of recurrent aphthous stomatitis with clofazimine.
The aim was to investigate the safety and efficacy of clofazimine for the treatment of recurrent aphthous stomatitis. ⋯ Clofazimine should be considered for the treatment of recurrent aphthous stomatitis.

Analysis of 46 maxillofacial fracture victims in the 2008 Wenchuan, China earthquake.
At 14:28 hours on May 12, 2008, a massive earthquake wracked most areas of Sichuan, China, causing catastrophic human loss. The aim of this study was to delineate the characteristics of victims with maxillofacial fractures in this disaster. ⋯ There is a variation of mechanism of injuries, age group, severity, patterns, concomitant injuries, and management of earthquake maxillofacial fractures. Knowledge of these characteristics provides useful strategies for patient care and prevention of further complications. A multidisciplinary and coordinated approach is important for optimum stabilization and ongoing treatment of victims of building collapse injury. The high percentage of PTSD confirms that psychologists should form an integral part of this multidisciplinary team.

Comparative StudyAccuracy and reliability of thermal threshold measurement in the chin using heat flux technique.
Neurosensory disturbance (NSD) occasionally develops in the chin following dental treatments, and evaluation of the involved nerve damage is important for treatment. The thermal-threshold test is a method of evaluating nerve sensations, but it is not widely used because its accuracy and reliability have not yet been determined. ⋯ The heat-flux technique is accurate and highly reliable. Therefore, it may be a useful method for determining the thermal threshold of the chin.
