Robot-assisted or pure laparoscopic nerve-sparing radical prostatectomy: What is the optimal procedure for the surgical margins? A single center expe…

2012

Objectives:  To compare positive surgical margin rates after robot-assisted and pure laparoscopic radical prostatectomy when neurovascular bundles are preserved, and to identify parameters affecting surgical margin status. Methods:  From March 2004 to January 2009, 279 consecutive prostatectomies with preservation of neurovascular bundles were carried out by the same surgeon: 175 robot-assisted radical prostatectomies and 104 laparoscopic radical prostatectomies. An intraperitoneal Montsouris's technique was used for all cases. Patient's age, body mass index, prostate weight, prostate-specific antigen level, clinical stage, preoperative and postoperative Gleason score, percentage of positiv…

Segmental ureterectomy vs. radical nephroureterectomy for ureteral carcinoma in patients with a preoperative glomerular filtration rate less than 90 …

2020

Objectives: To compare segmental ureterectomy (SU) and radical nephroureterectomy (RNU) in terms of overall survival (OS) and impact on postoperative renal function in patients treated for upper tract urothelial carcinoma (UTUC) of the ureter with preoperatively reduced estimated glomerular filtration rate (eGFR). Materials and methods: We retrospectively collected the data of consecutive patients treated for UTUC, in 6 Italian tertiary referral centers, from 2003 to 2013, and analyzed those treated with RNU or SU for ureteral cancer and with a preoperative eGFR <90 ml/min/1.73m2. The primary outcome was to compare the postoperative eGFR variation and the OS according to the surgical tec…

Retarded thymic involution and massive germinal center formation in NF-ATp-deficient mice.

1998

NF-ATp and NF-ATc are the most prominent nuclear NF-AT transcription factors in peripheral T lymphocytes. After T cell activation both factors bind to and control the promoters and enhancers of numerous lymphokine and receptor ligand genes. In order to define a specific role for NF-ATp in vivo we have inactivated the NF-ATp gene by gene targeting in mice. We show that NF-ATp deficiency leads to the accumulation of peripheral T cells with a “preactivated” phenotype, enhanced immune responses of T cells after secondary stimulation in vitro and severe defects in the proper termination of antigen responses, as shown by a reduced deletion of superantigen-reactive CD4+ T cells. These alterations …

Clinical characteristics and outcomes of thymoma-associated myasthenia gravis

2021

[Background and purpose] Prognosis of myasthenia gravis (MG) in patients with thymoma is not well established. Moreover, it is not clear whether thymoma recurrence or unresectable lesions entail a worse prognosis of MG.

RIPHeart (Remote Ischemic Preconditioning for Heart Surgery) Study: Myocardial Dysfunction, Postoperative Neurocognitive Dysfunction, and 1 Year Foll…

2018

Background Remote ischemic preconditioning ( RIPC ) has been suggested to protect against certain forms of organ injury after cardiac surgery. Previously, we reported the main results of RIPHeart (Remote Ischemic Preconditioning for Heart Surgery) Study, a multicenter trial randomizing 1403 cardiac surgery patients receiving either RIPC or sham‐ RIPC . Methods and Results In this follow‐up paper, we present 1‐year follow‐up of the composite primary end point and its individual components (all‐cause mortality, myocardial infarction, stroke and acute renal failure), in a sub‐group of patients, intraoperative myocardial dysfunction assessed by transesophageal echocardiography and the incidenc…

Definition of the Rectum An International, Expert-based Delphi Consensus

2019

Mini: A radiological, anatomic distinction between the rectum and sigmoid colon was agreed by consensus of international experts in rectal cancer using the Delphi Technique. Use of this landmark, “the sigmoid take-off,” may harmonize efforts in research and clinical practice to improve patient outcomes. Background: The wide global variation in the definition of the rectum has led to significant inconsistencies in trial recruitment, clinical management, and outcomes. Surgical technique and use of preoperative treatment for a cancer of the rectum and sigmoid colon are radically different and dependent on the local definitions employed by the clinical team. A consensus definition of the rectum…

The combination of different antiphospholipid antibody subgroups in the sera of patients with autoimmune diseases is a strong predictor for thrombosis

2003

Summary Objective: To determine the distribution of different antiphospholipid antibodies (APL-Ab) and their association with thrombosis in patients with autoimmune diseases. Methods: Clinical data and laboratory features of 30 patients with different autoimmune diseases with positive APL-Ab were retrospectively studied for a period of more than two years. Anti-cardiolipin (aCL), anti-phosphatidylserine (aPS) and anti-β2-glycoprotein I (aβ2-GPI) antibodies were determined by ELISA. Results: Autoantibodies that target only PS were detected in 53.3% (n=16) patients, aCL antibodies only were found in one patient (3,3%). In 43.3% (n=13), aPS were associated with elevated levels of aCL and/or aβ…
