Analysis of deep brain stimulation and ablative lesions in surgical treatment of movement disorders With emphasis on safety aspects

The shock heating of a laser-driven, direct-drive target can determine its stability by affecting Rayleigh-Taylor growth rates through target decompression and ablative stabilization. Measurements indicate that pulses that rise rapidly to 10(14) W/cm(2) produce shock-induced temperatures of approximately 25 eV, whereas more slowly rising pulses show less heating. Analysis of the observed target...

Gastric Antral Vascular Ectasia (GAVE) may be an enigmatic source of non-variceal upper GI bleeding associated with various systemic diseases such as connective tissue disorders, liver disease, and chronic renal failure. Successful treatment of GAVE continues to be a challenge and has evolved through the years. Currently, given the rapid response, safety, and efficacy, endoscopic ablative modal...

Early detection of metastatic disease within the liver by advanced diagnostic imaging has driven the rise of image-guided intervention for hepatic metastases. In this talk, we will explore the rationale, indications, technique and post procedure imaging findings of percutaneous treatments of liver metastases. Curative intent ablative therapies, such as radiofrequency ablation, microwave ablatio...

This invention involves method and apparatus for guiding ablative therapy of abnormal biological electrical excitation. In particular, it is designed for treatment of cardiac arrhythmias. In the method of this invention electrical signals are acquired from passive electrodes, and an inverse dipole method is used to identify the site of origin of an arrhytmia. The location of the tip of the abla...

Full face ablative resurfacing and fractional ablative resurfacing techniques are treatments of choice for facial rejuvenation of aged and photoaged skin. Both techniques were shown to be highly effective for dyschromia, fine lines and wrinkles [1-3]. Although better results are obtained with full resurfacing procedures, it comes with more downtime and more serious risks, when compared to fract...

Posted 08/24/2000 The rapid rise in incidence of adenocarcinoma of the esophagus and its established association with Barrett's esophagus has led to the development of numerous mucosal ablative techniques over the past decade in hopes of preempting progression to this cancer by eliminating its precursor lesion. Endoscopic spray cryotherapy is one of the newest modalities and holds tremendous pr...

We highlight a case of disabling myopathy following radioablative iodine treatment for follicular carcinoma of the thyroid. A 34-year-old man presented with a tender neck swelling, ultrasound and biopsy were suggestive of thyroid malignancy. Thyroidectomy was undertaken and histology confirmed follicular carcinoma of the thyroid. Treatment with ablative radioiodine followed and within days the ...
