Paragangliomas are neuroendocrine tumors located primarily in the head and neck region, but they can also occur at other sites. Confirming the preoperative diagnosis and detecting synchronous tumors may be difficult in some patients. Octreotide is a somatostatin analog that, when coupled to a radioisotope, produces a scintigraphic image of tumors expressing(More)
OBJECTIVES/HYPOTHESIS Disease-specific quality-of-life (QOL) assessment of patients with nasal valve compromise and symptomatic nasal obstruction has not been studied previously. The objectives of the study were to determine whether surgical treatment of the nasal valve improves disease-specific QOL and to identify clinical or demographic variables(More)
OBJECTIVES/HYPOTHESIS Octreotide is a somatostatin analogue that, when coupled to a radioisotope, produces a scintigraphic image of neuroendocrine tumors (NET) expressing somatostatin type 2 receptors (SSR 2). Octreotide scintigraphy (OS) may be useful in confirming the preoperative diagnosis of certain head and neck NET. Paragangliomas (PG), like many NET,(More)
The extended columellar strut-tip graft is a structural unit used in endonasal rhinoplasty that combines the attributes of the columellar strut and the tip graft. It is used to provide projection and contour to the nasal tip. Our goal with this study was to evaluate a 15-year experience with 155 patients who underwent rhinoplasty with the extended(More)
Orbital infection has long been the most common complication of sinusitis. In light of our increased knowledge of sinusitis, improved diagnostic tools, and new pharmacologic and surgical treatments, we investigated whether trends in diagnosis and treatment are changing. We reviewed the charts of all 43 patients who had been referred to our institution with(More)
This placebo-controlled, randomised, double-blind, cross-over human feeding study aimed to determine the prebiotic effect of agave fructans. A total of thirty-eight volunteers completed this trial. The treatment consisted of 3 weeks' supplementation with 5 g/d of prebiotic agave fructan (Predilife) or equivalent placebo (maltodextrin), followed by a 2-week(More)
Research into fault diagnosis in machines with a wide range of variable loads and speeds, such as wind turbines, is of great industrial interest. Analysis of the power signals emitted by wind turbines for the diagnosis of mechanical faults in their mechanical transmission chain is insufficient. A successful diagnosis requires the inclusion of accelerometers(More)
OBJECTIVE/HYPOTHESIS Examine and compare in detail the time courses of the auditory brainstem response (ABR) wave I amplitude and latency to the distortion-product otoacoustic emission (DPOAE) amplitude and phase measured in the rabbit model following deliberate obstruction of cochlear blood flow (CBF). METHODS Using a posterior fossa craniotomy in five(More)
