Spinal Cord Stimulation for Neurogenic Claudication Associated with Lumbar Spinal Stenosis.

Background: There is a debate on the long-term outcomes of surgical decompression for lumbar spinal stenosis (LSS) as compared to conservative treatment, with even more limited outcomes in repeat surgeries. Hence, other less invasive treatment modalities, such as neuromodulation with a modern spinal cord stimulator (SCS), could be considered in the spectrum of management options for symptoms of neurogenic claudication (NC) related to LSS as an alternative to surgery.

Objective: Assessing the outcomes and efficacy of SCS in neurogenic claudication in patients with or without a prior lumbar surgery.

Decreased heart dose with deep inspiration breath hold for the treatment of gastric lymphoma with IMRT.

We hypothesized that deep inspiration breath-hold (DIBH) and computed-tomography image-guided radiotherapy (CT-IGRT) may be beneficial to decrease dose to organs at risk (OARs), when treating the stomach with radiotherapy for lymphoma. We compared dosimetric parameters of OARs from plans generated using free-breathing (FB) versus DIBH for 10 patients with non-Hodgkin lymphoma involving the stomach treated with involved site radiotherapy. All patients had 4DCT and DIBH scans.
