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)
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)
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)
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)
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)
Two HLA identical brothers with mesangial IgA glomerulonephritis are reported. Patient 1 developed gross hematuria at age 12 and required chronic hemodialysis at age 20. Patient 2 presented at age 21 with gross hematuria and normal renal function, the follow up period is only 9 months. Neither of these patients had nerve deafness, ocular defects or(More)
Angiographic studies in a young girl aged 16 years who developed arterial hypertension during the course of Von Recklinghausen's disease, demonstrated the presence of an obliterated renal artery in a horseshoe kidney. The distal arterial segment was revascularized by two homolateral ureteral arteries. A full review of the literature revealed 30 cases of(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)
