Objective: Ionizing radiation is a critical threat to biomolecules, especially DNA. Various combinatorial compounds have been studied to protect this biomolecule. Melatonin has been reported as a direct and indirect free radical scavenger, but in this study, we explored the effect of melatonin on assisting in DNA repair by expression of Cdkn1a and Rad50; both of these genes are involved in DNA repair signaling, induced by radiation in rat peripheral blood.

Surgical resection of jugular foramen tumors poses a significant challenge to skull base surgeons with the selection of an appropriate surgical approach, a matter of some debate. Jugular foramen metastatic tumors may mimic paragangliomas, and in some selected cases surgical resection is needed. In this video, we demonstrate the microsurgical gross total resection of a jugular foramen tumor via a postauricular trans-jugular trans-sigmoid approach. Read More

In 2009, the American Society of Plastic Surgeons Task Force on Autologous Fat Grafting (AFG) determined that autologous fat grafting was a safe procedure with a relatively low rate of complications. This consensus opinion unleashed a wave of popularity as plastic surgeons discovered the procedures' efficacy in a wide variety of cosmetic and reconstructive indications. Frequently reported cosmetic applications include soft-tissue augmentation of breast, buttocks, hips, face, and hands, whereas reconstructive applications include adjunct for breast reconstruction contour problems, plantar fat pad improvement, and correction of various posttraumatic and surgical contour deformities.

Limb salvage is a key goal of tumor management around the knee, with surgical, medical, and radiologic treatment options. Primary bone and soft tissue sarcomas are optimally treated in specialist tertiary centers; however, metastatic disease is encountered in all aspects of radiologic practice, with overlap in the management strategies. Both specialist and generalist radiologists therefore need to be familiar with the expected normal appearances following these therapies and be able to recognize potential complications. Read More

Introduction: Up to 60% of patients with metastatic melanoma develop melanoma brain metastasis (MBM) during the course of their disease. Surgery, radiosurgery (SRS), stereotactic radiotherapy (SRT), and whole-brain radiation therapy (WBRT) or combinations of these are commonly used local treatment modalities. Inhibitory monoclonal antibodies against the CTLA-4 and PD-1 immune checkpoint receptors significantly improved the survival of metastatic melanoma patients, including patients with MBM. Read More

Purpose: The ability to identify, before treatment, those patients who will overreact to radiation therapy would have sound positive clinical implications. By focusing on DNA double-strand breaks recognition and repair proteins after irradiation, we recently demonstrated that the maximal number of phosphorylated ATM (pATM) nuclear foci in the first hour (pATMmax) after ex vivo irradiation correlated with postradiation therapy toxicity severity. We performed additional analyses of our whole collection of fibroblast lines to refine the predictive performance of our assay. Read More

We performed a case-control study to characterize the dose-volume relationship and other variables leading to hypothyroidism after head and neck (H&N) cancer radiation therapy (RT) in a homogenous Veterans Affairs (VA) population. All records of patients receiving RT for various H&N cancers at a single VA medical center between 2007 and 2013 (n = 143) were screened for post-RT thyroid stimulating hormone (TSH) levels (n = 77). The thyroid gland was contoured on each slice of the planning computed tomography scan when available (hypothyroid: n = 18; euthyroid > 2 years: n = 16), and dose-volume histograms based on physical dose and biologically equivalent dose (BED) were compared systematically to find the significant dose-volume thresholds that distinguish the patients who developed clinical hypothyroidism.
