Sequential imaging of genetically marked effector cells after adoptive transfer in vivo has greatly enhanced analyses of their biodistribution, growth, and activity both in animal models and in clinical trials of cellular immunotherapy. However, the immunogenicity of cells expressing xenogeneic reporter constructs limits their survival and clinical utility. To address this limitation, we have e...
Childhood familial pheochromocytoma was investigated in four patients by abdominal computed tomographic scan, [ IJmetaiodobenzylguanidine scan, and vena caval catecholamine sampling. Results conflicted with surgical findings. Computed tomographic scan identified all four adrenal tumors but missed two mid line tumors in one patient. [I]metaiodobenzylguanidine scan identified two of three adrenal...
Myocardial sympathetic neural function in professional athletes who had the long-term tremendous cardiac load has not been fully investigated by myocardial iodine-123-metaiodobenzylguanidine (MIBG) uptake in comparison with power spectral analysis (PSA) in electrocardiography. Eleven male professional cycle racers and age-matched 11 male healthy volunteers were enrolled in this study. The low f...
A 35-year-old woman presenting with abdominal pain was found to have mildly elevated catecholamine levels and a retroperitoneal mass. The patient underwent a negative I-123 MIBG scintigraphy scan and a nondiagnostic fine needle aspiration. Eleven years later the patient presented with a hypertensive emergency and markedly elevated catecholamine levels. A subsequent I-123 MIBG scintigraphy scan ...
Autonomic and olfactory dysfunctions are considered markers for preclinical diagnosis in Parkinson's disease (PD), because pathological changes in these systems can start before motor symptoms develop. We investigated whether cardiac sympathetic function and olfactory function are associated in PD. Participants comprised 40 nondemented patients with idiopathic PD, and age-matched controls. Card...
BACKGROUND Paraganglioma is an extra site of pheochromocytoma. Paraganglioma in the bladder is a very rare disease accounting for 0.06% of all bladder tumors. CASE PRESENTATION A 77-year-old Japanese man was referred to our department for the further examination of a bladder tumor detected on preoperative computed tomography of his gastric cancer. Cystoscopy revealed a submucosal tumor in the...
AIMS After acute myocardial infarction (AMI), regional denervation exceeding the scar area has been described. We sought to define the electrophysiologic correlates of denervated, but viable, myocardium by combining scintigraphic imaging with extensive electrocardiographic evaluation in AMI patients treated with early reperfusion therapy. METHODS AND RESULTS Within 14 days after AMI, 67 conse...
