Abstract: Osteoradionecrosis (ORN) is a severe and devastating late complication of radiotherapy in patients with head and neck cancer. Management of ORN remains controversial and the current approach has been focused on debridement, systemic antibiotics, and...
Abstract: Advances in the management of oral malignancy have resulted in significant improvements in survival and functional outcome. Ablation of oral tissues and radiotherapy render many patients unable to wear conventional prostheses, and these patients are, thus,...
Abstract: An 81-year-old male with early-stage laryngeal carcinoma had been treated with 60 Gy curative radiotherapy. He complained of a sore throat, foul odor in the mouth, progressive dyspnea, and fever 2 months after the completion of radiotherapy. Direct...
Abstract: Over the past 40 years, hyperbaric oxygen (HBO2) therapy has been recommended and used in a wide variety of medical conditions. In the 1950s, HBO2 was first used as a treatment, in addition to radiation, for head and neck cancers and cervical cancer. Many...
Abstract: Hyperbaric oxygen (HBO2) is used to promote healing in irradiated tissues, but concern persists about the possibility that it may promote residual tumor growth. The tumor growth of SQ20B and Detroit 562 head and neck squamous cell carcinoma xenografts were...
Abstract: The use of photodynamic therapy (PDT) to treat malignant tumors involves a photosensitizing drug, light, and oxygen. Since PDT requires oxygen, the purpose of this study was to investigate whether increased oxygen tension increases cell death compared with...
Abstract: Metastatic tumors of the intestinal tract from extra-abdominal sites are rare. In esophageal cancer, the liver, lung and the bones are the most common sites of metastases. Metastasis to intestines are very rare. A 54-year old male was admitted with...
Abstract: Brain cyst formation of temporal lobe induced by radionecrosis in ear carcinoma is rare. A 73-year-old man with basosquamous carcinoma of the left external ear canal received excision of tumor and postoperative radiation therapy in 1992. For osteonecrosis of...
Abstract: Discoveries of the beneficial cellular and biochemical effects have strengthened the rationale for the administration of hyperbaric oxygen therapy (HBO2) as an adjunctive therapy for the treatment of osteoradionecrosis (ORN). Malignancies, however, are...
Abstract: We report a case of branch retinal artery occlusion (BRAO) in a patient with iron-deficiency anemia. Various ophthalmological and laboratory studies were performed. A 32-year-old man had a sudden decrease of vision in his left eye to counting fingers at 30...
