Comparing open and robotic salvage radical prostatectomy after radiotherapy: predictors and outcomes.

Introduction: In the present study, we aim to provide more evidence about benefits of salvage radical prostatectomy (SRP). Our main objective is to assess prostatic-specific antigen control and postoperative urinary incontinence in open and robotic approaches as primary outcomes.

Materials And Methods: After the Institutional Review Board approval (IRB00010193), we retrospectively analyzed 76 consecutive patients who underwent open or robot-assisted SRP for locally relapsed prostate cancer between 2004 and 2019 at the Urology Department of Hospital Italiano de Buenos Aires, Argentina.

Ephrin-B1 Is a Novel Biomarker of Bladder Cancer Aggressiveness. Studies in Murine Models and in Human Samples.

Bladder cancer (BC) is the ninth most common cancer worldwide, but molecular changes are still under study. During tumor progression, Epithelial cadherin (E-cadherin) expression is altered and β-catenin may be translocated to the nucleus, where it acts as co-transcription factor of tumor invasion associated genes. This investigation further characterizes E-cadherin and β-catenin associated changes in BC, by combining bioinformatics, an experimental murine cell model (MB49/MB49-I) and human BC samples.

Bilateral pheochromocytoma after kidney transplantation in neurofibromatosis type 1.

We present the case of a 25-year-old male with a history of neurofibromatosis type 1 and bilateral pheochromocytoma 4 years after kidney transplantation that was successfully treated with simultaneous bilateral posterior retroperitoneoscopic adrenalectomy. Learning points: Hypertensive patients with NF1 should always be screened for pheochromocytoma. Pheochromocytoma is rarely associated with transplantation, but it must be ruled out in patients with genetic susceptibility.

von Hippel-Lindau mutants in renal cell carcinoma are regulated by increased expression of RSUME.

Renal cell carcinoma (RCC) is the major cause of death among patients with von Hippel-Lindau (VHL) disease. Resistance to therapies targeting tumor angiogenesis opens the question about the underlying mechanisms. Previously we have described that RWDD3 or RSUME (RWD domain-containing protein SUMO Enhancer) sumoylates and binds VHL protein and negatively regulates HIF degradation, leading to xenograft RCC tumor growth in mice.

Helicopter Emergency Medical Services in Buenos Aires: An Operational Overview.

As part of the emergency medical care system, helicopter emergency medical services (HEMS) have a different crew composition from the traditional team. HEMS consist of a pilot, doctor, and firefighter with rescue skills and training in basic life support on board an air ambulance. This allows the adaptation to different environments and increases the varieties of air procedures normally performed.

[Histopathology and molecular profile of a case of prostatic Ewing sarcoma].

We report a case of Ewing sarcoma localized in the prostate gland of a 33-year-old patient without bone or soft tissue involvement. Evidence of EWS and FLI1 gene translocation was detected by fluorescence in situ hybridization (FISH). This is an unusual case with an interesting clinical presentation; indeed, only a few cases have been reported to date and not all have the supporting biological studies now considered essential for the diagnosis.

Mucoid degeneration of the anterior cruciate ligament: MRI, clinical, intraoperative, and histological findings.

Purpose: To describe the clinical, MRI, intraoperative, and histological features of mucoid degeneration of the anterior cruciate ligament (ACL).

Methods: This study included 10 patients (average age 47 years, range 19-69 years) who underwent surgery due to clinical diagnoses of mucoid degeneration of the ACL. All patients underwent preoperative magnetic resonance imaging (MRI) and were arthroscopically treated.

Direct 64-row MDCT venography in the diagnosis of an inferior vena cava leiomyosarcoma.

We report the usefulness of a technique called direct-MDCT venography in the diagnostic workup of a patient with an inferior vena cava leiomyosarcoma. The technique consists in the injection of contrast agent through both lower limbs achieving maximum enhancement in the inferior vena cava. Images are similar to those of the gold standard conventional cavography.
