Generalisation to novel exemplars of learned shape categories based on visual and auditory spatial cues does not benefit from multisensory information.

Although the integration of information across multiple senses can enhance object representations in memory, how multisensory information affects the formation of categories is uncertain. In particular, it is unclear to what extent categories formed from multisensory information benefit object recognition over unisensory inputs. Two experiments investigated the categorisation of novel auditory and visual objects, with categories defined by spatial similarity, and tested generalisation to novel exemplars.

Multisensory perception constrains the formation of object categories: a review of evidence from sensory-driven and predictive processes on categorical decisions.

Although object categorization is a fundamental cognitive ability, it is also a complex process going beyond the perception and organization of sensory stimulation. Here we review existing evidence about how the human brain acquires and organizes multisensory inputs into object representations that may lead to conceptual knowledge in memory. We first focus on evidence for two processes on object perception, multisensory integration of redundant information (e.

A Brief Explanation on Surgical Approaches for Treatment of Different Brain Tumors.

The main goal of brain tumor surgery is to achieve gross total tumor resection without postoperative complications and permanent new deficits. However, when the lesion is located close or within eloquent brain areas, cranial nerves, and/or major brain vessels, it is imperative to balance the extent of resection with the risk of harming the patient, by following a so-called maximal safe resection philosophy. This view implies a shift from an approach-guided attitude, in which few standard surgical approaches are used to treat almost all intracranial tumors, to a pathology-guided one, with surgical approaches actually tailored to the specific tumor that has to be treated with specific dedicated pre- and intraoperative tools and techniques.

IgE-Mediated Immune Response and Antibody-Mediated Rejection.

Background And Objectives: Active antibody-mediated rejection is the main cause of kidney transplant loss, sharing with SLE the alloimmune response and the systemic activation of the IFN- pathway. IgE-mediated immune response plays a key role in the development of SLE nephritis and is associated with IFN- secretion. The aim of our study was to investigate IgE-mediated immune response in antibody-mediated rejection.

Is there a clinical role for frozen section analysis during partial nephrectomy? A multicenter experience over 10 years.

Background: Frozen section analysis (FSA) is frequently performed during partial nephrectomy (PN). We investigate the utility of intraoperative FSA by evaluating its impact on final surgical margin (SM) status.

Methods: Between January 1995 and December 2005, a series of patients who were treated with open PN for renal cell carcinoma was prospectively analyzed.

Surgical correction of Peyronie's disease via tunica albuginea plication: long-term follow-up.

Peyronie's disease (PD) is an acquired connective tissue disorder of the tunica albuginea with fibrosis and inflammation that lead to palpable plaques formation, penile curvature, and pain during erection. Patients report negative effects on main domains such as physical appearance and self-image, sexual function, and performance. The aim of this study was to evaluate plication of the albuginea outcomes after a long-term follow-up period.

Does site of specimen extraction affect incisional hernia rate after robot assisted laparoscopic radical prostatectomy?

Background: Robot assisted laparoscopic radical prostatectomy (RALP) spread in the last decade as a minimally invasive alternative to open radical prostatectomy for men with localized prostate cancer. It is associated with excellent surgical, functional and oncological results with less postoperative pain and shorter convalescence. Anyway, the development of an incisional hernia (IH), may negate known benefits as it can lead not only to bothersome symptoms but also to severe complications, such as bowel obstruction, strangulation and perforation.

Thulium laser enucleation (ThuLEP) versus transurethral resection of the prostate in saline (TURis): A randomized prospective trial to compare intra and early postoperative outcomes.

Objective: To compare clinical intra and early postoperative outcomes between thulium laser transurethral enucleation of the prostate (ThuLEP) and transurethral bipolar resection of the prostate (TURis) for treating benign prostatic hyperplasia (BPH) in a prospective randomized trial.

Methods: The study randomized 208 consecutive patients with BPH to ThuLEP (n=102) or TURis (n=106). For all patients were evaluated preoperatively with regards to blood loss, catheterization time, irrigation volume, hospital stay and operative time.

Immediate and Catastrophic Antibody-Mediated Rejection in a Lung Transplant Recipient With Anti-Angiotensin II Receptor Type 1 and Anti-Endothelin-1 Receptor Type A Antibodies.

Preexisting donor-specific anti-HLA antibodies (DSAs) have been associated with reduced survival of lung allografts. However, antibodies with specificities other than HLA may have a detrimental role on the lung transplant outcome. A young man with cystic fibrosis underwent lung transplantation with organs from a suitable deceased donor.

Application and Uses of Electronic Noses for Clinical Diagnosis on Urine Samples: A Review.

The electronic nose is able to provide useful information through the analysis of the volatile organic compounds in body fluids, such as exhaled breath, urine and blood. This paper focuses on the review of electronic nose studies and applications in the specific field of medical diagnostics based on the analysis of the gaseous headspace of human urine, in order to provide a broad overview of the state of the art and thus enhance future developments in this field. The research in this field is rather recent and still in progress, and there are several aspects that need to be investigated more into depth, not only to develop and improve specific electronic noses for different diseases, but also with the aim to discover and analyse the connections between specific diseases and the body fluids odour.

Endorectal multiparametric 3-tesla magnetic resonance imaging associated with systematic cognitive biopsies does not increase prostate cancer detection rate: a randomized prospective trial.

Purpose: To investigate prostate cancer (PC) detection rate, employing endorectal multiparametric 3-tesla magnetic resonance imaging (MRI) driving subsequent cognitive systematic prostatic biopsy (CSPB) versus a homogenous group of patients who did not undergo endorectal MRI.

Materials And Methods: A series of patients with a first negative biopsy were enrolled in the study. Patients were randomized into two groups: Group A: patients underwent MRI and subsequent CSPB; Group B: patients that did not undergo MRI.

Open partial nephrectomy: ancient art or currently available technique?

Renal cell carcinoma (RCC) accounts for 3 % of adult solid tumors, with the highest incidence between 50 and 70 years of age. Nephron-sparing surgery was initially reserved to patients with small renal masses detected in anatomically or functionally solitary kidney or in the presence of multiple bilateral tumors or hereditary forms of RCC, which posed a high risk of developing a tumor in the contralateral kidney. Nowadays, partial nephrectomy (PN) has grown up to an established approach for the treatment of small renal masses.

Two-dimensional neovascular complexity is significantly higher in nontumor prostate tissue than in low-risk prostate cancer.

Purpose: Prostate cancer is the most frequent cancer in men in Europe. A major focus in urology is the identification of new biomarkers with improved accuracy in patients with low-risk prostate cancer. Here, we evaluated two-dimensional neovascular complexity in prostate tumor and nontumor biopsy cores by use of a computer-aided image analysis system and assessed the correlations between the results and selected clinical and pathological parameters of prostate carcinoma.

Olfactory system of highly trained dogs detects prostate cancer in urine samples.

Purpose: We established diagnostic accuracy in terms of the sensitivity and specificity with which a rigorously trained canine olfactory system could recognize specific volatile organic compounds of prostate cancer in urine samples.

Materials And Methods: Two 3-year-old female German Shepherd Explosion Detection Dogs were trained to identify prostate cancer specific volatile organic compounds in urine samples. They were tested on 362 patients with prostate cancer (range low risk to metastatic) and on 540 healthy controls with no nonneoplastic disease or nonprostatic tumor.

Senescent remodeling of the innate and adaptive immune system in the elderly men with prostate cancer.

Despite years of intensive investigation that has been made in understanding prostate cancer, it remains a major cause of death in men worldwide. Prostate cancer emerges from multiple alterations that induce changes in expression patterns of genes and proteins that function in networks controlling critical cellular events. Based on the exponential aging of the population and the increasing life expectancy in industrialized Western countries, prostate cancer in the elderly men is becoming a disease of increasing significance.

Mast cells as a potential prognostic marker in prostate cancer.

Despite years of intensive investigation that has been made in understanding prostate cancer, it remains one of the major men's health issues and the leading cause of death worldwide. It is now ascertained that prostate cancer emerges from multiple spontaneous and/or inherited alterations that induce changes in expression patterns of genes and proteins that function in complex networks controlling critical cellular events. It is now accepted that several innate and adaptive immune cells, including T- and B-lymphocytes, macrophages, natural killer cells, dendritic cells, neutrophils, eosinophils, and mast cells (MCs), infiltrate the prostate cancer.

Impact of Real-Time Elastography versus Systematic Prostate Biopsy Method on Cancer Detection Rate in Men with a Serum Prostate-Specific Antigen between 2.5 and 10 ng/mL.

The actual gold standard for the diagnosis of prostate cancer includes the serum prostate-specific antigen, the digital rectal examination, and the ultrasound-guided systematic prostate biopsy sampling. In the last years, the real-time elastography has been introduced as an imaging technique to increase the detection rate of prostate cancer and simultaneously reduce the number of biopsies sampled for a single patient. Here, we evaluated a consecutive series of 102 patients with negative digital-rectal examination and transrectal ultrasound, and prostate-specific antigen value ranging between 2.

Glomerular c4d immunoreactivity in acute rejection biopsies of renal transplant patients.

In renal transplant patients, glomerulitis may be present in all types of acute rejection, often accompanied by diffuse C4d staining of peritubular capillaries: C4d3 positivity in more than 50% of peritubular capillaries. It may progress to chronic transplant glomerulopathy, characterized by capillary basement membrane multilayering, proteinuria, and progressive loss of renal function. While C4d3 is a recognized marker of an antibody-mediated reaction, the significance of glomerular C4d (GlC4d) staining is unknown.

Can a Gleason 6 or Less Microfocus of Prostate Cancer in One Biopsy and Prostate-Specific Antigen Level <10 ng/mL Be Defined as the Archetype of Low-Risk Prostate Disease?

Prostate cancer (PC) remains a cause of death worldwide. Here we investigate whether a single microfocus of PC at the biopsy (graded as Gleason 6 or less, ≤5% occupancy) and the PSA <10 ng/mL can define the archetype of low-risk prostate disease. 4500 consecutive patients were enrolled.

Glomerulitis and endothelial cell enlargement in C4d+ and C4d- acute rejections of renal transplant patients.

In acute rejection after renal transplant, glomerulitis is characterized by mononuclear cells in glomerular capillaries and endothelial cell enlargement. In association with C4d deposition in peritubular capillaries, glomerulitis is a feature of acute antibody-mediated rejection. Prognosis in C4d(+) rejection is poorer than in C4d(-) rejection.
