Radiation Sensitivity and Radiation Necrosis in the Short Telomere Syndromes

Radiation Sensitivity and Radiation Necrosis in the Short Telomere Syndromes

We report radiation necrosis as the first manifestation of a germline mutation in telomerase. A 60-year-old woman presented with defective wound healing after multiple surgical explorations of the chest wall to exclude breast cancer recurrence. At age 42, she received a diagnosis of stage I estrogen receptor–positive left breast infiltrating ductal carcinoma on routine mammography. Lumpectomy w...

Distorted Reflector Antennas: Radiation Pattern Sensitivity to the Surface Distortions

The high-frequency performance of the reflector antennas is mainly limited by the surface. It has been shown that distortions on different regions of the reflector surface can have different effects on the radiation performance. In other words, degradation of the radiation pattern due to the presence of surface distortions is sensitive to the location and behavior of the surface distortion prof...

Radiation-induced temporal lobe necrosis.

Because nasopharyngeal carcinoma has a high frequency of intracranial spread, adequate radiation treatment inevitably results in irradiation of the temporal lobes. A 38-year-old woman who was treated for nasopharyn-geal carcinoma 30 months previously and had been given radiation therapy (70 Gy to the primary site) presented with headaches. Computed tomography (CT) showed an enhancing lesion in ...

Radiation-induced femoral head necrosis.

There are very few cases of radiation-induced femoral head necrosis described in the literature, therefore, this case will add new knowledge and highlights important aspects in the diagnosis and management of this uncommon condition. Our patient was 74 years old and presented with left hip and groin pain for 8 months, with no previous history of trauma or osteoarthritis. However, he had been tr...
