Most of current concepts for a visual prosthesis are based on neuronal electrical stimulation at different locations along the visual pathways within the central nervous system. The different designs of visual prostheses are named according to their locations (i.e., cortical, optic nerve, subretinal, and epiretinal). Visual loss caused by outer retinal(More)
Fifteen patients with breast cancer and skeletal metastases who had bone pain refractory to opioid analgesics and who were not eligible for or had not responded to local field radiotherapy, were treated with strontium-89. All patients had received previous treatment with chemotherapy and radiotherapy for bone metastases. Severity of bone pain, sleeping(More)
This report describes the authors’ experience with a unique endoluminal, endoscopically delivered and retrieved gastroduodenojejunal bypass sleeve, including short-term weight loss and changes in comorbidities. A prospective, single-center trial was designed. The patients were morbidly obese individuals who met the National Institutes of Health criteria for(More)
Sensitive methods are required to record electrical evoked potentials over the visual cortex to evaluate the efficacy and safety of a retinal prosthesis before it can be implanted on the retinal surface of patients afflicted by outer retinal diseases. This study was designed to examine subdural electrodes as a mean to evaluate cortical evoked potentials in(More)
Rheumatoid arthritis is a chronic polyarthritis in which active inflammed joints coexist with joints in remission. We performed bone scans (99mTc-DPD) and 99mTc human polyclonal immunoglobulin G scans (99mTc-IgG) in 18 patients with rheumatoid arthritis to assess the uptake in actively inflamed joints and in joints in which remission after inflammation had(More)
PURPOSE To report the clinical, electrophysiologic, and histologic findings of different concentrations of indocyanine green (ICG) injected into the vitreous cavity of rabbit eyes. METHODS Forty-two rabbits underwent intravitreal injection of 0.1 mL of ICG in three different concentrations: 0.5 mg/mL (250 mOsm), 5 mg/mL (270 mOsm), and 25 mg/mL (170(More)
Surgical reconstruction for patients with symptomatic lower extremity arterial occlusive disease is successful when a suitable distal target vessel is present. In patients with unreconstructable disease, practical surgical options are at a minimum. We report our initial experience with dorsal venous arch arterialization (DVAA) for limb salvage. Patients(More)
To test iodine-125 labelled low-density lipoprotein (125I-LDL), polyclonal indium-111 labelled immunoglobulin G (111In-IgG) and iodine-125 labelled endothelin-1 uptake in metabolically active atheromatous plaques after arterial wall injury, we performed balloon de-endothelialization of carotid arteries or abdominal aortas in 24 New Zealand male rabbits(More)
Here, we report the first series of patients with 1-year implantation of a novel, endoluminal, endoscopically delivered and retrieved gastro-duodeno-jejunal bypass sleeve (GJBS) (ValenTx, Inc. Carpinteria, CA, USA). In this report, we present the safety, feasibility of the device, weight loss, and changes in comorbidities. A prospective, single-center,(More)
To assess chemotherapeutically induced myocardial damage, myosin-specific antibody scans and ejection fraction measurements were performed in 32 patients with breast cancer and in 9 patients with other tumours. All patients had received chemotherapy including anthracyclines. The ejection fraction decreased by ≥ 10% in 14 of 41 (34%) patients after(More)
