We wished to determine whether different types of dietary protein might have different effects on calcium metabolism and on the propensity for renal stone formation. Fifteen young normal subjects were studied during three 12-day dietary periods during which their diet contained vegetable protein, vegetable and egg protein, or animal protein. While these(More)
Using the ambulatory protocol previously described, 241 patients with nephrolithiasis were evaluated. They could be categorized into 10 groups from the results obtained. Absorptive hypercalciuria type I (87 per cent male) comprised 24.5 per cent and was characterized by normocalcemia, normal fasting urinary calcium (less than 0.11 mg/100 ml glomerular(More)
Renal involvement in thyroid diseases is an unusual event. Antineutrophil cytoplasmic antibody (ANCA) associated vasculitis has been reported in propylthiouracil-treated patients. Membranous glomerulonephritis has been reported in association with both antithyroglobulin and thyroid antimicrosomal antibodies. The development of membranous glomerulonephritis(More)
The purpose of this study was to prospectively compare the effectiveness of administering medroxyprogesterone acetate (MPA; 20 mg/day) in either the first (protocol A) or last (protocol B) 12-week period along with a 6-month course of the GnRH analog (GnRH-a; leuprolide acetate; 1 mg/day, sc) on uterine and leiomyomata volumes and hormone (estradiol, LH,(More)
Dual-energy x-ray absorptiometry and single-photon absorptiometry were used to determine bone density at the lumbar spine and radial shaft in 62 patients with absorptive hypercalciuria, 27 patients with fasting hypercalciuria, and 31 nonhypercalciuric stone formers. Lumbar bone density was significantly lower in patients with absorptive (-10%) as well as in(More)
OBJECTIVE To test whether intermittent treatment with slow-release sodium fluoride and continuous calcium citrate supplementation inhibits vertebral fractures without causing fluoride complications. DESIGN A placebo-controlled, randomized trial. SETTING Outpatient setting of specialty clinics in Dallas and Temple, Texas. INTERVENTIONS Slow-release(More)
Earlier studies have shown that an oral sodium (Na) load may induce hypercalciuria in previously normocalciuric subjects and may also increase intestinal calcium (Ca) absorption. To probe the cause of the increased intestinal Ca absorption, we simultaneously measured parathyroid function, serum 1,25-dihydroxyvitamin D [1,25-(OH)2D], and fractional(More)
Thirty-two (32) patients with primary hyperparathyroidism (17 with prior localization surgery, 15 without) were studied by a combination of computed tomography (CT), ultrasound (US), nuclear medicine (NM), and magnetic resonance imaging (MRI) for parathyroid adenoma localization. The sensitivity and true-positive ratio of each imaging technique and various(More)
