BACKGROUND Several cardiovascular risk factors are present in patients with chronic renal failure (CRF), among which are systemic inflammation and hyperhomocysteinemia. Increased oxidative stress, endothelial activation/dysfunction, and coagulation activation are considered integral components of the inflammatory response, but have also been proposed as(More)
OBJECTIVE To study the incidence and relevance of ectopic adrenal tissue in pediatric patients who underwent groin surgical explorations. MATERIALS AND METHODS We studied 1120 patients with groin surgical explorations during a period of 8 consecutive years. Patients' clinical data and histological findings were analyzed. RESULTS We found ectopic adrenal(More)
OBJECTIVE Retroperitoneoscopy has shown that US involution is not synonymous with complete regression of the dysplastic renal parenchyma in US-involuted multicystic dysplastic kidney (MCDK). The objective is to analyze the meaning of this results. PATIENTS AND METHODS 16 patients (nine girls and seven boys) with unilateral MCDK that showed complete(More)
OBJECTIVE Megacalycosis or Puigvert's disease is a congenital anomaly of renal development characterized by caliceal dilatation, an increased number of calyces, associated with hypoplasia of the pyramids of Malpighi, and a normal renal pelvis. Renal function is always normal and there is no evidence of obstruction to urinary flow. The foregoing are(More)
Acute scrotum is an exceptional form of presentation of acute appendicitis in the pediatric age group. Only 14 cases have been described in literature. The authors report a case of an 8-year-old boy with a 12-hour history of right hemiscrotal pain secondary to acute retrocecal nonperforated appendicitis. Surgical exploration showed a patent "processus(More)
We report our experience of renal transplantation in three patients treated for Wilms' tumor (with lung metastasis in two of them), and review 26 previously reported cases in order to define the current indications of transplantation in this setting. Our patients, aged 5-12 years, were transplanted 13-95 months after completion of Wilms' tumor treatment.(More)
Major vascular injury during laparoscopic procedures is a rare but catastrophic complication. We report a pediatric case of aortic laceration during the setup phase of diagnostic laparoscopy in a 5-year-old girl with recurrent abdominal pain. The Veress needle inserted below the umbilicus confirmed the proper placement by use of a saline-filled syringe. The(More)
BACKGROUND A defect in platelet function is the main determinant of the prolonged bleeding time in chronic renal failure (CRF). We previously reported a significant correlation between platelet abnormalities and elevated plasma markers of plasmin and thrombin generation. Our aim was to explore the effect of inhibiting both plasmin action with tranexamic(More)
Plasma von Willebrand factor antigen, soluble thrombomodulin, and tissue factor were increased in 31 patients with severe chronic renal failure (creatinine clearance <20 ml/min) under conservative treatment, whereas plasminogen activator inhibitor antigen did not differ significantly from healthy controls. No correlation among plasma levels of these(More)
