[Role of ultrasonography in the primary diagnosis of lymphomas].

Objective: To determine the diagnostic value of ultrasonography and its capabilities in evaluating the involvement of abdominal organs and peripheral lymph nodes, in analyzing the morphological subtypes in lymphomas, in choose the lymph node that is most informative for a histological study.

Subject And Methods: 193 patients with lymphomas, including 85 (44%) with lymphogranulomatosis and 108 (56%) with non-Hodgkin's lymphomas who had been treated at the clinical units of the Prof. R.

POSTERIOR CRUCIATE LIGAMENT RECONSTRUCTION WITH AUTOGRAFT OF THE DOUBLE SEMITENDINOSUS MUSCLES AND MIDDLE THIRD OF THE QUADRICEPS TENDON WITH DOUBLE FEMORAL AND SINGLE TIBIAL TUNNELS: CLINICAL RESULTS IN TWO YEARS FOLLOW UP.

Objective: To evaluate the surgical aspects that may offer good anatomic and functional results in posterior cruciate ligament (PCL) reconstruction using an autologous graft of the quadriceps tendon and double semitendinosus through a double femoral tunnel.

Methods: Fourteen patients with isolated PCL lesions, instability and pain were operated on by arthroscopy and evaluated according to the International Knee Documentation Committee (IKDC) and Lysholm scales. Posterior knee laxity was examined with a KT1000 arthrometer.

Urinary collecting system invasion is an independent prognostic factor of organ confined renal cell carcinoma.

Purpose: We evaluated urinary collecting system invasion as a prognostic parameter of renal cell carcinoma.

Materials And Methods: A total of 1,124 patients who underwent nephrectomy for a renal tumor at 5 European centers were included in this retrospective study. Several variables were analyzed including urinary collecting system invasion, age, sex, TNM stage, Fuhrman grade, histological subtype, Eastern Cooperative Oncology Group performance status and cancer specific survival.

Positive surgical margin appears to have negligible impact on survival of renal cell carcinomas treated by nephron-sparing surgery.

Background: The occurrence of positive surgical margins (PSMs) after partial nephrectomy (PN) is rare, and little is known about their natural history.

Objective: To identify predictive factors of cancer recurrence and related death in patients having a PSM following PN.

Design, Setting, And Participants: Some 111 patients with a PSM were identified from a multicentre retrospective survey and were compared with 664 negative surgical margin (NSM) patients.

Age as only predictive factor for successful sperm recovery in patients with Klinefelter's syndrome.

The study was performed to determine factors affecting successful sperm retrieval by testicular sperm extraction in patients with nonmosaic Klinefelter's syndrome (KS). From May 2001 to February 2007, 27 azoospermic patients were diagnosed as having nonmosaic KS. All patients underwent sperm testicular extraction.
