Multiple/bilateral renal tumors in patients with Birt-Hogg-Dubé syndrome.

Objective: To describe our findings in four patients with multiple/bilateral renal cell carcinoma (RCC) and Birt-Hogg-Dubé (BHD) syndrome.

Patients And Methods: A series of four patients with BHD syndrome and RCC is analyzed. Patient charts were reviewed for age, sex, presentation, various clinical manifestations, imaging, management and outcome.

Thromboembolic risk factors in patients undergoing kidney transplant: implication of abnormally short activated partial thromboplastin time.

This study was designed to examine the relationship of short activated partial thromboplastin time (aPTT) and prothrombin time (PT) to the incidence of thromboembolic events, hereditary and acquired coagulation defects associated with an increased risk of thrombosis, or cardiovascular diseases in patients undergoing renal transplantation. The prevalence of these conditions in our patients (n = 436) was 55%. Forty-two percent of the patients had short aPTT or PT.
