Radiation Therapy for Benign Disease: Keloids, Macular Degeneration, Orbital Pseudotumor, Pterygium, Peyronie Disease, Trigeminal Neuralgia.

Although the use of ionizing radiation on malignant conditions has been well established, its application on benign conditions has not been fully accepted and has been inadequately recognized by health care providers outside of radiation therapy. Most frequently, radiation therapy in these benign conditions is used along with other treatment modalities, such as surgery, when the condition causes significant disability or could even lead to death. Radiation therapy can be helpful for inflammatory/proliferative disorders.

A Dosimetric Comparison of Intensity-Modulated Proton Therapy, Volumetric-Modulated Arc Therapy, and 4π Non-Coplanar Intensity-Modulated Radiation Therapy for a Patient with Parameningeal Rhabdomyosarcoma.

Rhabdomyosarcoma (RMS) is the most common soft tissue sarcoma in children and manifests as two major histological subtypes: embryonal and alveolar. The five-year local failure rate for RMS at parameningeal sites (middle ear, mastoid region, nasal cavity, etc.) is around 17% despite multiple Intergroup Rhabdomyosarcoma Study Group (IRS) trials conducted to determine the optimal radiation treatment regimen.

Treatment and Outcomes of Primary Urethra Cancer.

Background: Urethral cancer is a rare malignancy, representing <1% of all malignancies. Optimal management, due to its rarity, presents as a treatment dilemma for physicians. There is a lack of consensus regarding treatment as large randomized trials cannot be performed; thus, optimal management decisions rely on study of retrospective cases.

Characterization of the translocation-competent complex between the Helicobacter pylori oncogenic protein CagA and the accessory protein CagF.

CagA is a virulence factor that Helicobacter pylori inject into gastric epithelial cells through a type IV secretion system where it can cause gastric adenocarcinoma. Translocation is dependent on the presence of secretion signals found in both the N- and C-terminal domains of CagA and an interaction with the accessory protein CagF. However, the molecular basis of this essential protein-protein interaction is not fully understood.
