Posttransplantation lymphoproliferative disorders in renal transplant recipients: report of over 20 years of experience.

Introduction: Despite the benefits of immunosuppressive medications to improve graft function, they have several adverse effects, such as development of neoplasms in renal transplant recipients. Posttransplantation lymphoproliferative disorders (PTLDs) are not uncommon complications, so we conducted a study to evaluate the characteristics of affected patients.

Methods: We enrolled 2117 kidney recipients from June 1984 to March 2004 in order to find pathological and clinical evidence of neoplasms.

Calcium and phosphorus metabolism disturbances after renal transplantation.

Introduction: Several studies have noted that, despite beneficial correction of abnormalities of mineral metabolism after successful renal transplantation, renal functional recovery is incomplete. Also, persistence of hyperparathyroidism and metabolic acidosis among patients with chronic impairment of graft function together with the use of loop diuretics and immunosuppressive drugs with adverse effects may alter mineral metabolism. We determined calcium and phosphorus levels in recipients.

A randomized clinical trial comparing hydrocolloid, phenytoin and simple dressings for the treatment of pressure ulcers [ISRCTN33429693].

Background: Pressure sores are important and common complications of spinal cord injury. Many preventive and therapeutic approaches have been tried and new trials are evolving. One relatively recent method is application of a hydrocolloid dressing (HD).
