The increasing global prevalence of nephrolithiasis continues to burden the healthcare delivery systems of industrialized nations and exact a disproportionate humanitarian toll on populations of the developing world (1). In the United States alone, the prevalence of nephrolithiasis is nearly twice the rate reported in the 1960s (2-5). The subsequent rise in(More)
Rhythmical brain activity in the range between four and eight Hz acquired over frontal-midline EEG recording sites - so called frontal-midline theta activity - is regarded as one of the most prominent neural signatures of sustained attention. It is reported to parametrically increase with cognitive load and is thought to be generated in medial prefrontal(More)
Neural grafting is a potential strategy to help restore auditory function following loss of spiral ganglion cells. As a first step towards the reconstruction of a neural pathway from the cochlea to the brainstem, we have examined the survival of fetal dorsal root ganglion (DRG) neurons allografted into the cochlea of adult guinea pigs. In some animals(More)

Ectopic calcification is a driving force for a variety of diseases, including kidney stones and atherosclerosis, but initiating factors remain largely unknown. Given its importance in seemingly divergent disease processes, identifying fundamental principal actors for ectopic calcification may have broad translational significance. Here we establish a(More)
PURPOSE Calyceal selection for percutaneous renal access is critical for safe, effective performance of percutaneous nephrolithotomy. Available anatomical evidence is contradictory and incomplete. We present detailed renal calyceal anatomy obtained from in vivo 3-dimentional computerized tomography renderings. MATERIALS AND METHODS A total of 60(More)
Background. Long-term urologic complications after total hip arthroplasty are rare, and reports in the urologic literature are scant. We present a recent case and review the relevant literature. Case. A 77-year-old man was referred to the urology clinic for a single episode of gross painless hematuria, abnormal urine cytology, and pelvic mass. He had a(More)
Urinary stone disease is the third most common condition affecting the urinary tract. It contributes to a great deal of morbidity for both men and women, and cost the United States (US) over 5.3 billion dollars in 2000 alone. Moreover, it is associated with systemic diseases such as hypertension, diabetes, and other components of the metabolic syndrome.(More)
A 43-year-old patient has just left the office. Her primary care physician had dutifully evaluated her recent complaint of vague abdominal pain with an abdominal ultrasound. The multiple, small, punctate hyperechoic lesions in the kidney were deemed concerning for renal calculi and an abdominal computed tomography (CT) scan was ordered to better delineate(More)
This paper describes in detail a novel optoelectronic system designed to measure drug absorption in the anterior segment of the eye following topical application of drug formulations. This minimally invasive measurement technique offers both a method for determining drug concentration in human eyes, and demonstrates an alternative to current testing(More)
