Juvenile diabetes mellitus--a risk factor for postoperative venous thromboembolism?

In a retrospective analysis of 125 patients and a prospective evaluation of 83 patients with terminal uremia undergoing kidney transplantation, juvenile diabetes mellitus was found to be a significant risk factor for the development of postoperative thromboembolism. We found a high frequency of objectively verified thromboembolism despite the relatively young age of the patients. Besides diabetes, no other clinical risk factor differed between patients with and without thrombosis.

Deep vein thrombosis after renal transplantation: a prospective analysis of frequency and risk factors.

In a prospective study the frequency of deep vein thrombosis during the first 3 weeks after kidney transplantation has been evaluated using the combination of thermography and strain-gauge plethysmography for objective diagnosis. 83 consecutive patients were included, 33 with juvenile diabetes mellitus. The overall frequency of thrombosis was 24.1%, diabetes mellitus being a significant risk factor. No other risk factors were found. The transplant did not influence the venous outflow from the corresponding leg. Plasminogen activator activity in the iliac vein wall at transplantation did not differ between patients with and without thrombosis.

Renal transplantation in patients with endstage diabetic nephropathy.

Eighty-six renal transplantations were performed in 69 patients with endstage diabetic nephropathy. Cadaveric kidneys were used in 77 of the transplantations. Most of the patients had severe retinopathy. Patients with severe cardiopathy and neuropathy were not accepted for transplantation. After one year 61% of the patients were alive, after three years 43%, all except one with functioning graft. The quality of life of the survivors was acceptable, only two requiring nursing care. It is concluded that renal transplantation in patients with diabetic nephropathy is justified in selected patients.

Renal transplantation in polycystic renal disease--a joint Scandinavian report.

During the period 1965-1977, a total of 339 patients with polycystic renal disease received at least 1 renal transplant at one of 10 transplant centres in Scandinavia. Patient survival at one year was 67%. The one year graft survival of 319 cadaveric grafts was 40%. The average age of the patient was 56.7 years. Patients who were 60 years or older (93 patients) had a significantly poorer patient and graft survival at one year (50% and 29.5% respectively). Patients receiving kidneys with O incompatibilities did significantly better than other donor-recipient combinations. Previous blood transfusions were associated with better graft prognosis, though the difference was only significant for 2 years. The incidence of posttransplant urinary tract infection (present in 47% of all the patients) was twice as common in patients with a history of pretransplant urinary tract infection (seen in 41% of all the patients). There was no association between posttransplant septicaemia and either pre- or post-transplant urinary tract infection. Only 10.5% of the patients were nephrectomized at the time of transplantation, half of these had urinary tract infection. Twenty-four per cent of the patients were nephrectomized in the posttransplant period, half of these because of infection. There was no difference in the graft survival data of the patients with or without pretransplant urinary tract infection. These findings justify a restrictive practice with regard to pretransplant nephrectomy in patients with polycystic renal disease.

Chylous ascites following retroperitoneal lymphadenectomy: report of 2 cases with guidelines for diagnosis and treatment.

Two cases of chylous ascites following retroperitoneal lymphadenectomy are presented. The first case, a 3-year-old girl, undersent a right radical nephrectomy and retroperitoneal lymph node dissection for Wilms' tumor. Chylous ascites developed postoperatively and resolved after 3 months of supportive therapy. The second case, a 45-year-old woman, underwent a right radical nephrectomy and retroperitoneal lymph node dissection for renal carcinoma. Chylous ascites occurred postoperatively and resolved after a single paracentesis. Diagnosis, evaluation, and therapeutic modalities are outlined and the literature is reviewed.

Focal infarction of the testicle in a child simulating testicular tumor.

Enlargement of an undescended testicle in a 6 1/2-month-old-child resulted in radical orchiectomy. Pathological diagnosis was focal infarction of the testicle. This disorder must be considered in the differential diagnosis of testicular enlargement in the infant and child.

Internal fracture of a pediatric broviac catheter.

Indwelling central venous catheters have become an integral part of the care of bone marrow transplant patients. Current technology provides the physician with repeated, reliable accesses to the central venous system via centrally placed silastic (Broviac) catheters. This report describes an unusual mechanical complication and a method for catheter salvage.
