Radiotherapy-induced uterine cacinosarcoma: A case report and review of the literature.

Radiation therapy is a very effective treatment modality for cervical cancer, but unfortunately, ionizing radiation is associated with many side effects, including secondary cancer formation. We report a case of carcinosarcoma of the uterus in a woman with a history of pelvic irradiation for cervical carcinoma. A review of the literature was performed to present the incidence, optimal management, and prognosis for post-radiation uterine carcinosarcoma.

Cell-Based Transplantation versus Cell Homing Approaches for Pulp-Dentin Complex Regeneration.

Regenerative dentistry has paved the way for a new era for the replacement of damaged dental tissues. Whether the causative factor is dental caries, trauma, or chemical insult, the loss of the pulp vitality constitutes one of the major health problems worldwide. Two regenerative therapies were introduced for a fully functional pulp-dentin complex regeneration, namely, cell-based (cell transplantation) and cell homing (through revascularization or homing by injection of stem cells in situ or intravenously) therapies, with each demonstrating advantages as well as drawbacks, especially in clinical application. The present review is aimed at elaborating on these two techniques in the treatment of irreversibly inflamed or necrotic pulp, which is aimed at regenerating a fully functional pulp-dentin complex.
