Stereotactic Radiosurgery for Trigeminal Neuralgia and Movement Disorders

September 13, 2019 Medical Technology Directory

Health Problem: Movement disorders, such as Parkinson disease (PD) and essential tremor (ET), are neurological conditions that can cause tremor that cannot be controlled with medication in some patients. ET is the most common movement disorder, affecting an estimated 7 million Americans and approximately 1% to 6% of the adult population > 40 years of age. Estimates suggest that 1.5 million Americans are affected by PD and approximately 60,000 new cases of this disorder are diagnosed annually.   Technology Description: Stereotactic radiosurgery (SRS) is a therapeutic technique that focuses high dosages of radiation onto small, precisely defined targets in the brain, such as a...

Proton Beam Therapy for Head and Neck Cancer in Pediatric Patients

September 13, 2019 Medical Technology Directory

Health Problem: Rhabdomyosarcoma (RMS) is the most common soft-tissue sarcoma diagnosed in children and the third most common pediatric extracranial solid tumor. Although progress in the treatment for RMS has led to improved survival, some children have nonresponsive or recurrent disease, and current treatment modalities can lead to long-term complications in survivors. Each year in the United States, approximately 340 children are newly diagnosed with RMS. The 5-year survival rate for persons 19 years of age or older improved from 49% in the late 1970s to 64% in the 2000s. The head and neck is the most common site for RMS,...

Radioactive Yttrium-90 Microspheres for the Treatment of Primary Unresectable Liver Cancer for Downstaging or as a Bridge to Transplantation or Surgery

September 11, 2019 Medical Technology Directory

Health Problem: Hepatocellular carcinoma (HCC) is the most common liver malignancy in the United States, accounting for approximately 90% of primary liver cancers. The definitive therapies for HCC are surgical resection, tumor ablation, and liver transplantation; however, most patients are not eligible for these therapies due to the overall burden or severity of their disease. Patients whose tumor is outside the criteria for resection or transplantation may benefit from a locoregional therapy (LRT) or systemic therapy to downstage to within criteria. Due to the lack of available donor organs, patients may elect to undergo LRTs as a means to avoid...

Risk-Reducing (Prophylactic) Salpingectomy

September 10, 2019 Medical Technology Directory

Health Problem: In the United States, ovarian cancer ranks fifth among cancer deaths. This type of cancer is often not detected at an early stage since early signs or symptoms are usually absent or easily overlooked. There is no effective method for screening women at normal risk for ovarian cancer. Technology Description: Bilateral salpingectomy refers to the preventive surgical removal of both fallopian tubes with the goal of reducing the risk of ovarian cancer in women at normal risk of the disease. Although salpingectomy can be performed alone as a substitute for tubal ligation, it is usually performed opportunistically as an adjunct to...

Greater Occipital Nerve Blocks for Treatment of Migraine Headaches

September 5, 2019 Medical Technology Directory

Health Problem: Migraine is a chronic, familial neurological disorder characterized by episodic headache attacks that are typically unilateral and often debilitating, lasting for hours or days and occurring multiple times per month. It is the third most prevalent illness in the world and considered the most disabling of the neurological disorders. It affects approximately 18% to 20% of women and 6% to 10% of men in the United States, most commonly in those aged 25 to 55 years. Technology Description: This report focuses on the efficacy and safety of greater occipital nerve block (GONB) for the preventive treatment of chronic migraine headaches in...
