The paraventricular hypothalamic nucleus (PVH) contains many neurons that innervate the brainstem, but information regarding their target sites remains incomplete. Here we labeled neurons in the rat PVH with an anterograde axonal tracer, Phaseolus vulgaris leucoagglutinin (PHAL), and studied their descending projections in reference to specific neuronal(More)
This study identified factors associated with an improvement in low back pain (LBP) at six-month follow-up after total hip arthroplasty (THA). Data from a national registry of 3054 patients were analyzed. Factors under analysis included demographics, comorbid conditions, operative and nonoperative joint pain severity, physical function, and mental health.(More)
BACKGROUND Subfascial wound suction drains are commonly used after spinal surgery to decrease the incidence of post-operative hematoma. However, there is a paucity of literature regarding their effectiveness. OBJECTIVE To report four cases of post-operative spinal epidural hematoma causing massive neurological deficit in patients who had subfascial(More)
The transcription factor Phox2b is necessary for the development of the nucleus of the solitary tract (NTS). In this brainstem nucleus, Phox2b is expressed exclusively within a subpopulation of glutamatergic neurons. The present experiments in the adult rat were designed to test whether this subpopulation includes the aldosterone-sensitive NTS neurons,(More)
Ulnar neuropathy at the elbow is the second most common compression neuropathy of the upper extremity and poses a challenge for treating physicians. Lack of a standardized grading system, outcome measures, or surgical indications can make treatment decisions difficult to justify. Conclusions drawn from the available literature include similar rates of good(More)
OBJECTIVES To examine (1) the validity of ultrasound imaging to measure osteophytes and (2) the association between osteophytes and insertional Achilles tendinopathy (IAT). DESIGN Case-control study. SETTING Academic medical center. PARTICIPANTS Persons with chronic unilateral IAT (n=20; mean age, 58.7±8.3y; 10 [50%] women) and age- and sex-matched(More)
This pilot study investigated the feasibility of Google Glass to assist visualization of fluoroscopic images during percutaneous pinning of hand fractures. Cadavers were used to compare total time to pin each fracture and total number of radiographs per fracture from a mini C-arm. A FluoroScan monitor was used for radiographic visualization compared to(More)
UNLABELLED Orchestral musicians commonly have playing-related symptoms (PRS) but few use worker's compensation (WC) insurance for assessment and treatment. The purpose of this study was to examine the frequency of, and factors related to, filing a WC claim among musicians. METHODS An online questionnaire was completed by 261 members of the International(More)
