Endophytic to total tumour volume ratio: An added variable to patients with T1b/T2 renal tumours undergoing partial nephrectomy.

Introduction: Partial nephrectomy is the standard of care to patients with small renal masses. It is still encouraged to larger tumours whenever feasible. The aim of this study is to look for the endophytic to total tumour volume ratio as an added variable to study the complexity of partial nephrectomy to patients with T1b/ T2 renal tumours.

Partial Nephrectomy for T1b/T2 Renal Mass: An Added Shift from Radical Nephrectomy.

The aim of our study was to show our short-term experience in managing large renal masses (cT1b/T2) through partial nephrectomy (PN) over the last 3 years. Retrospective data collection for all patients managed by PN for renal masses larger than 4 cm over the last 3 years. Epidemiological data were collected.

Predictors of bleeding complications following percutaneous image-guided liver biopsy: a scoping review.

Purpose: Percutaneous tissue biopsy is a mainstay of diagnostic and interventional radiology, providing a minimally invasive method for diagnosing malignant and benign disease. The purpose of this review was to collect and summarize the best available evidence regarding the risk factors associated with bleeding complications in image-guided liver biopsy.

Methods: A literature review was performed, searching Medline, EMBASE, CINAHL, the Cochrane Library, the National Institute for Health and Care Excellence (NICE) and Canadian Agency for Drugs and Technology in Health (CADTH) databases for any studies evaluating bleeding complications in image-guided liver biopsy.

Response Evaluation Criteria in Solid Tumors (RECIST) criteria are superior to European Association for Study of the Liver (EASL) criteria at 1 month follow-up for predicting long-term survival in patients treated with transarterial chemoembolization before liver transplantation for hepatocellular cancer.

Purpose: To determine whether response to transarterial chemoembolization can predict survival in patients with hepatocellular carcinoma (HCC) who are candidates for orthotopic liver transplantation (LT) and if either European Association for Study of the Liver (EASL) criteria or Response Evaluation Criteria in Solid Tumors (RECIST) criteria are more accurate for this purpose.

Materials And Methods: A retrospective review of all patients who underwent LT after transarterial chemoembolization between January 2005 and June 2011 was performed. Follow-up imaging with multiphasic computed tomography or magnetic resonance imaging was performed 1 month after transarterial chemoembolization and every 3 months thereafter until LT.

Screening for cognitive impairment in a stroke prevention clinic using the MoCA.

Background: Screening for cognitive impairment is recommended in patients with cerebrovascular disease. We sought to establish the incidence of cognitive impairment using the Montreal Cognitive Assessment (MoCA) in a cohort of consecutive patients attending our stroke prevention clinic (SPC), and to determine whether a subset of the MoCA could be derived for use in this busy clinical setting.

Methods: The MoCA was administered to 102 patients.

Obesometric factors associated with increased skin-to-stone distances in renal stone patients.

Introduction: Obese patients are at increased risk for renal stones as well as treatment failures due to increased skin-to-stone distances (SSD) and harder stone compositions. We investigated the relationships between obesometric parameters (body mass index [BMI], body fat distribution and obesity-related hormone levels) with SSD and stone hardness.

Materials And Methods: We prospectively enrolled patients undergoing stone interventions at our institution.

Surfer's myelopathy--an unusual cause of acute spinal cord ischemia: a case report and review of the literature.

Surfer's myelopathy is an emergent medical condition, representing a rare type of nontraumatic injury of the spinal cord, triggered by continued hyperextension of the back in inexperienced surfers. Subsequent acute spinal cord ischemia is the main pathological "substrate" for extensive cord myelopathy, determining potential neurological damage and thus predicting a patient's outcome. Awareness of the regional vascular anatomy and correct interpretation of the radiological findings are essential in making a precise diagnosis.

Pituitary abscess: an unexpected diagnosis.

The pituitary gland can demonstrate a variety of pathologies with different clinical presentations. Amongst them, pituitary abscess is a rare infectious disease for which contrast-enhanced MRI aids the diagnostic pathway. We present a 16-year-old girl with imaging and surgical findings consistent with primary pituitary abscess.
