The aim of this study was to examine the efficacy and safety of duloxetine, a balanced and potent dual reuptake inhibitor of serotonin and norepinephrine, in the management of diabetic peripheral neuropathic pain. Serotonin and norepinephrine are thought to inhibit pain via descending pain pathways. In a 12-week, multicenter, double-blind study, 457(More)
It has been proposed that osteocyte viability plays an important role in bone integrity, and that bone loss in osteoporosis may be partially due to osteocyte cell death following estrogen depletion. Osteoporosis treatments such as bisphosphonates can inhibit osteocyte apoptosis which in turn may also reduce remodeling. Consequently, microcracks in bone(More)
Using an ovariectomized (OVX) ovine model, we provide an analysis of the timing of changes in bone following estrogen deficiency. The expression of genes known to regulate osteoclastogenesis, matrix production, and mineralization, as measured by real-time RT-PCR, was significantly increased by 12 months; and increased expression was maintained through to 31(More)
Pretreatment of sodium arsenite reduces hypoxanthine-guanine phosphoribosyltransferase mutagenicity and overcomes the inhibition of mitosis and cell proliferation but has no apparent effect on the cytotoxicity and clastogenicity in methyl methanesulfonate (MMS)-treated Chinese hamster ovary cells. Posttreatment of sodium arsenite drastically increases the(More)
Compact bone makes up approximately 80% of the human skeletal mass. This study examines the effect of estrogen deficiency on compact bone turnover and associated geometrical structural adaptation over a 31-month period in a large animal model. Twenty-seven skeletally mature sheep were divided into control (n = 16) and ovariectomy group (OVX, n = 11).(More)
BACKGROUND AND PURPOSE The CT grading system for otosclerosis was proposed by Symons and Fanning in 2005. The purpose of this study was to determine if this CT grading system has high interobserver and intraobserver agreement. MATERIALS AND METHODS All 997 petrous bone CTs performed between December 2000 and September 2007 were reviewed. A total of 81(More)
An acute intracranial embolus may be associated with a hyperdense artery sign on CT, related to acute thrombus within the affected artery, a phenomenon that is well known and has been extensively documented. We present an unusual case of a middle cerebral artery territory acute infarct with a hypodense artery on CT. The Hounsfield unit attenuation of the(More)
BACKGROUND AND PURPOSE The posterior thyroid tubercle, also known as ZT, is an important surgical landmark due to its close proximity to the recurrent laryngeal nerve. A recent case of ZT with a nodular configuration caused clinical concern but was shown on biopsy to be normal thyroid tissue. The purpose of this study was to review a series of CT neck(More)
This article is an update and literature review of the clinical and neuroimaging findings of the commonly known rickettsial, spirochetal, and eukaryotic parasitic infections. Being familiar with clinical presentation and imaging findings of these infections is crucial for early diagnosis and treatment especially in patients who live in or have a travel(More)
