To clarify the risk factors for chronic renal failure in idiopathic IgA glomerulonephritis (IgA-GN), we performed a dual study on 282 patients using both standard univariate statistical methods and the multivariate regression model of Cox. During a follow-up ranging from 1 to 36 years, with a mean of 8 years, 18% of the patients (50/282) had gone into(More)
Complete study of the sella turcica requires multidirectional tomography. The authors have studied 200 radiographs of normal adults and noted the percentage of variants of each anatomical feature on both standard radiographs and tomograms. The greatest drawback of the standard radiograph is the difficulty in objectively evaluating the effect of(More)
A total of 127 patients from 8 hospitals were randomized into 1 of 2 exit-site care regimes to evaluate their effect on rate of exit-site infection (ESI). Group 1 used povidone iodine and nonocclusive dressings changed 2 to 3 times weekly; Group 2 simply cleansed the exit site with nondisinfectant soap and water. Incidence, cause, duration, and treatment of(More)
Retroperitoneal teratomas are rare in adults; they are malignant in 25.8% of cases. The authors report two benign cases in which radiologic examination was essential in establishing the diagnosis. Irregular calcifications, which are visible in 61.5% of reported cases, cannot be considered a sign of benignity, since 12.5% of calcified tumors were malignant.(More)
No consensus has been reached on the serum 25-hydroxyvitamin D [25(OH)D] levels required to ensure optimal bone health around menarche. We searched for a possible interaction of 25(OH)D levels and calcium intake on lumbar spine mineralization and on biologic features of bone metabolism in healthy late-pubertal girls. Lumbar spine parameters (ie, area,(More)
OBJECTIVE To develop a cost-effective strategy for improving osteoporosis management in patients admitted to an orthopedic surgery department for low-energy fractures. METHODS From November 2003 to July 2004, all patients over 50 years admitted to the orthopedics department of the Caen Teaching Hospital (France) for low-energy fractures were identified(More)
Congenital malformations of the inferior vena cava are characterized by their diversity which is related to the complexity of the embryological development of this vessel. The authors review the embryogenesis and origin of the different segments of the inferior vena cava and describe the various types of malformation, including the causative embryological(More)
Antiresorptive agents are effective in preventing and treating postmenopausal osteoporosis, provided they are taken as directed. Regular physical examinations including height measurements may fail to ensure optimal compliance. Bone mineral density (BMD) measurement is indispensable for determining whether treatment is warranted. The measurement can be(More)
Familial cases of mesangial IgA glomerulonephritis (MGN) have raised the possibility of a genetic control in this disease. In 50 patients with MGN, diagnosed on renal biopsy, and in 105 controls, we have compared the distribution of HLA antigens (A and B loci). We found a significant increase in the frequency of HLA Bw35 antigen in the patient group(More)
