Context: The first European Association of Urology (EAU) guidelines on incontinence were published in 2001. These guidelines were periodically updated in past years. Objective: The aim of this paper is to present a summary of the 2009 update of the EAU guidelines on urinary incontinence (UI). Evidence acquisition: The EAU working panel was part of the 4th International Consultation on Incontinence (ICI) and, with permission of the ICI, extracted the relevant data. The methodology of the 4th ICI was a comprehensive literature review by international experts and consensus formation. In addition, level of evidence was rated according to a modified Oxford system and grades of recommendation were given accordingly. Evidence summary: A full version of the EAU guidelines on urinary incontinence is available as a printed document (extended and short form) and as a CD-ROM from the EAU office or online from the EAU Web site ( The extent and invasiveness of assessment of UI depends on severity and/or complexity of symptoms and clinical signs and is different for men, women, frail older persons, children, and patients with neuropathy. At the level of initial management, basic diagnostic tests are applied to exclude an underlying disease or condition such as urinary tract infection. Treatment is mostly conservative (lifestyle interventions, physiotherapy, physical therapy, pharmacotherapy) and is of an empirical nature. At the level of specialised management (when primary therapy failed, diagnosis is unclear, or symptoms and/or signs are complex/severe), more elaborate assessment is generally required, including imaging, endoscopy, and urodynamics. Treatment options include invasive interventions and surgery. Conclusions: Treatment options for UI are rapidly expanding. These EAU guidelines provide ratings of the evidence (guided by evidence-based medicine) and graded recommendations for the appropriate assessment and according treatment options and put them into clinical perspective. © 2010 European Association of Urology.

The experiments were not randomized and the investigators were not blinded to allocation during experiments and outcome assessment. ARC-Net, University of Verona: approval number 1885 from the Integrated University Hospital Trust (AOUI) Ethics Committee (Comitato Etico Azienda Ospedaliera Universitaria Integrata) approved in their meeting of 17 November 2010, documented by the ethics committee 52070/CE on 22 November 2010 and formalized by the Health Director of the AOUI on the order of the General Manager with protocol 52438 on 23 November 2010. APGI: Sydney South West Area Health Service Human Research Ethics Committee, western zone (protocol number 2006/54); Sydney Local Health District Human Research Ethics Committee (X11-0220); Northern Sydney Central Coast Health Harbour Human Research Ethics Committee (0612-251M); Royal Adelaide Hospital Human Research Ethics Committee (091107a); Metro South Human Research Ethics Committee (09/QPAH/220); South Metropolitan Area Health Service Human Research Ethics Committee (09/324); Southern Adelaide Health Service/Flinders University Human Research Ethics Committee (167/10); Sydney West Area Health Service Human Research Ethics Committee (Westmead campus) (HREC2002/3/4.19); The University of Queensland Medical Research Ethics Committee (2009000745); Greenslopes Private Hospital Ethics Committee (09/34); North Shore Private Hospital Ethics Committee. Baylor College of Medicine: Institutional Review Board protocol numbers H-29198 (Baylor College of Medicine tissue resource), H-21332 (Genomes and Genetics at the BCM-HGSC), and H-32711(Cancer Specimen Biobanking and Genomics). Patients were recruited and consent obtained for genomic sequencing through the ARC-Net Research Centre at Verona University, Australian Pancreatic Cancer Genome Initiative (APGI), and Baylor College of Medicine as part of the ICGC ( A patient criterion for admission to the study was that they were clinically sporadic. This information was acquired through direct interviews with participants and a questionnaire regarding their personal history and that of relatives with regard to pancreas cancers and any other cancers during anamnesis. Clinical records were also used to clarify familial history based on patient indications. Samples were prospectively and consecutively acquired through institutions affiliated with the Australian Pancreatic Cancer Genome Initiative. Samples from the ARC-Net biobank are the result of consecutive collections from a single centre. All tissue samples were processed as previously described5151. Representative sections were reviewed independently by at least one additional pathologist with specific expertise in pancreatic diseases. Samples either had full face frozen sectioning performed in optimal cutting temperature (OCT) medium, or the ends excised and processed in formalin to verify the presence of tumour in the sample to be sequenced and to estimate the percentage of neoplastic cells in the sample relative to stromal cells. Macrodissection was performed if required to excise areas that did not contain neoplastic epithelium. Tumour cellularity was determined using SNP arrays (Illumina) and the qpure tool9. PanNET is a rare tumour type and the samples were collected via an international network. We estimate that with 98 unique patients in the discovery cohort, we will achieve 90% power for 90% of genes to detect mutations that occur at a frequency of ~10% above the background rate for PanNET (assuming a somatic mutation frequency of more than 2 per Mb)52. Cancer and matched normal colonic mucosa were collected at the time of surgical resection from the Royal Brisbane and Women’s Hospital and snap frozen in liquid nitrogen. A biallelic germline mutation in the MUTYH gene was detected by restriction fragment length polymorphism analysis and confirmed by automated sequencing to be the G382D mutation (or ENST00000450313.5 G396D, ClinVar#5294) in both alleles53. The primary antibodies used for immunohistochemical staining were: cytokeratin 8/18 (5D3, Novocastra), chromogranin A (DAK-A3, Dako), and CD99 (O13, Biolegend). Antibodies and staining conditions have been described elsewhere39. Whole-genome sequencing with 100-bp paired reads was performed with a HiSEQ2000 (Illumina). Sequence data were mapped to a GRCh37 using BWA and BAM files are available in the EGA (accession number: EGAS00001001732). Somatic mutations and germline variants were detected using a previously described consensus mutation calling strategy11. Mutations were annotated with gene consequence using SNPeff. The pathogenicity of germline variants was predicted using cancer-specific and locus-specific genetic databases, medical literature, computational predictions with ENSEMBL Variant Effect Predictor (VEP) annotation, and second hits identified in the tumour genome. Intogen27 was used to find somatic genes that were significantly mutated. Somatic structural variants were identified using the qSV tool as previously described10, 11, 17. Coding mutations are included in supplementary tables and all mutations have been uploaded to the International Cancer Genome Consortium Data Coordination Center. Mutational signatures were predicted using a published framework14. Essentially, the 96-substitution classification was determined for each sample. The signatures were compared to other validated signatures and the prevalence of each signature per megabase was determined. Somatic copy number was estimated using high density SNP arrays and the GAP tool12. Arm level copy number data were clustered using Ward’s method, Euclidian distance. GISTIC13 was used to identify recurrent regions of copy number change. The whole genome sequence data was used to determine the length of the telomeres in each sample using the qMotif tool. Essentially, qMotif determines telomeric DNA content by calculating the number of reads that harbour the telomere motif (TTAGG), and then estimates the relative length of telomeres in the tumour compared to the normal. qMotif is available online ( Telomere length was validated by qPCR as previously described54. RNASeq library preparation and sequencing were performed as previously described55. Essentially, sequencing reads were mapped to transcripts corresponding to ensemble 70 annotations using RSEM. RSEM data were normalized using TMM (weighted trimmed mean of M-values) as implemented in the R package ‘edgeR’. For downstream analyses, normalized RSEM data were converted to counts per million (c.p.m.) and log transformed. Genes without at least 1 c.p.m. in 20% of the sample were excluded from further analysis55. Unsupervised class discovery was performed using consensus clustering as implemented in the ConsensusClusterPlus R package56. The top 2,000 most variable genes were used as input. Differential gene expression analysis between representative samples was performed using the R package ‘edgeR’57. Ontology and pathway enrichment analysis was performed using the R package ‘dnet’58. PanNET class enrichment using published gene signatures44 was performed using Gene Set Variation Analysis (GSVA) as described previously55. Two strategies were used to verify fusion transcripts. For verification of EWSR1–BEND2 fusions, cDNAs were synthesized using the SuperScript VILO cDNA synthesis kit (Thermofisher) with 1 μg purified total RNA. For each fusion sequence, three samples were used: the PanNET sample containing the fusion, the PanNET sample without that fusion, and a non-neoplastic pancreatic sample. The RT–PCR product were evaluated on the Agilent 2100 Bioanalyzer (Agilent Technologies) and verified by sequencing using the 3130XL Genetic Analyzer (Life Technologies). Primers specific for EWSR1–BEND2 fusion genes are available upon request. To identify the EWSR1 fusion partner in the case ITNET_2045, a real-time RT–PCR translocation panel for detecting specific Ewing sarcoma fusion transcripts was applied as described59. Following identification of the fusion partner, PCR amplicons were subjected to sequencing using the 3130XL Genetic Analyzer. EWSR1 rearrangements were assayed on paraffin-embedded tissue sections using a commercial split-signal probe (Vysis LSI EWSR1 (22q12) Dual Colour, Break Apart Rearrangement FISH Probe Kit) that consists of a mixture of two FISH DNA probes. One probe (~500 kb) is labelled in SpectrumOrange and flanks the 5′ side of the EWSR1 gene, extending through intron 4, and the second probe (~1,100 kb) is labelled in SpectrumGreen and flanks the 3′ side of the EWSR1 gene, with a 7-kb gap between the two probes. With this setting, the assay enables the detection of rearrangements with breakpoints spanning introns 7–10 of the EWSR1 gene. Hybridization was performed according to the manufacturer’s instructions and scoring of tissue sections was assessed as described elsewhere60, counting at least 100 nuclei per slide. Recurrently mutated genes identified by whole-genome sequencing were independently evaluated in a series of 62 PaNETs from the ARC-Net Research Centre, University of Verona. Four Ion Ampliseq Custom panels (Thermofisher) were designed to target the entire coding regions and flanking intron–exon junctions of the following genes: MEN1, DAXX, ATRX, PTEN and TSC2 (panel 1); DEPDC5, TSC1 and SETD2 (panel 2); ARID1A and MTOR (panel 3); CHEK2 and MUTYH (panel 4). Twenty nanograms of DNA were used per multiplex PCR amplification. The quality of the obtained libraries was evaluated by the Agilent 2100 Bioanalyzer on chip electrophoresis. Emulsion PCR was performed with the OneTouch system (Thermofisher). Sequencing was run on the Ion Torrent Personal Genome Machine (PGM, Thermofisher) loaded with 316 or 318 chips. Data analysis, including alignment to the hg19 human reference genome and variant calling, was done using Torrent Suite Software v4.0 (Thermofisher). Filtered variants were annotated using a custom pipeline based on the Variant Effector Predictor (VEP) software. Alignments were visually verified with the Integrative Genomics Viewer: IGV v2.3 (Broad Institute). There is no contiguous structure available for CHEK2, so we produced a model of isoform C using PDBid 3i6w61 as a template for predicting the structure of sequence O96017. Modelling was carried out within the YASARA suite of programs62 and consisted of an initial BLAST search for suitable templates followed by alignment, building of loops not present in selected template structure and energy minimization in explicit solvent. Modelling was carried out in the absence of a phosphopeptide ligand, which was added on completion by aligning the model with structure 1GXC and merging the ligand contained therein with the model structure. Similarly, MUTYH is represented by discontinuous structures and so this too was modelled using PDBids 3N5N and 4YPR as templates together with sequence NP_036354.1. Having constructed both models, amino acid substitutions were carried out to make the wild-type sequences conform to the variants described above. Each substitution was carried out independently and the resulting variant structures were subject to simulated annealing energy minimization using the AMBER force field. The resulting energy-minimized structures formed the basis of the predictions. CHEK2 site mutants were generated by site-directed mutagenesis of wild-type pCMV–FLAG CHEK2 (primer sequences in Supplementary Table 16). Proteins were expressed in HEK293T, a highly transfectable derivative of HEK293 cells that were retrieved from the cell culture bank at the QIMR Berghofer medical research institute. Cells were authenticated by STR profiling and were negative for mycoplasma. Transfected cells were lysed in NP-40 modified RIPA with protease and phosphatase inhibitors. Protein expression levels were analysed by western blotting with anti-FLAG antibodies and imaging HRP luminescent signal on a CCD camera (Fuji) and quantifying in MultiGauge software (Fuji). Kinase assays were performed using recombinant GST–CDC25C (amino acids 200–256) as substrate, essentially as described63. Kinase assay quantification was performed by scintillation counting of excised gel bands in OptiPhase scintillant (Perkin Elmer) using a Tri-Carb 2100TR beta counter (Packard). Counts for each reaction set were expressed as a fraction of the wild type. All experiments were performed at least three times. The date of diagnosis and the date and cause of death for each patient were obtained from the Central Cancer Registry and treating clinicians. Median survival was estimated using the Kaplan–Meier method and the difference was tested using the log-rank test. P values of less than 0.05 were considered statistically significant. The hazard ratio and its 95% confidence interval were estimated using Cox proportional hazard regression modelling. The correlation between DAXX or ATRX mutational status and other clinico-pathological variables was calculated using the χ2 test. Statistical analysis was performed using StatView 5.0 Software (Abacus Systems). Disease-specific survival was used as the primary endpoint. Genome sequencing data presented in this study have been submitted to the European Genome-Phenome Archive under accession number EGAS00001001732 (

Median survival has increased in people with cystic fibrosis (CF) during the past six decades, which has led to an increased number of adults with CF. The future impact of changes in CF demographics has not been evaluated. The aim of this study was to estimate the number of children and adults with CF in 34 European countries by 2025. Data were obtained from the European Cystic Fibrosis Society Patient Registry. Population forecasts were performed for countries that have extensive CF population coverage and at least 4 years of longitudinal data by modelling future entering and exiting flows in registry cohorts. For the other countries, population projections were performed based on assumptions from knowledge of current CF epidemiology. Western European countries' forecasts indicate that an increase in the overall number of CF patients by 2025, by approximately 50%, corresponds to an increase by 20% and by 75% in children and adults, respectively. In Eastern European countries the projections suggest a predominant increase in the CF child population, although the CF adult population would also increase. It was concluded that a large increase in the adult CF population is expected in the next decade. A significant increase in adult CF services throughout Europe is urgently required.

We report an outbreak of linezolid-resistant Staphylococcus haemolyticus strains (MIC 32 mg/L) in patients admitted to the Verona University Hospital Intensive Care Unit. The strains proved to be clonally related at pulsed field gel electrophoresis. All the strains showed the G2576T mutation responsible for linezolid-resistance and retained their resistance even after several passages on antibiotic-free medium. After a decade of linezolid use, multifocal emergence of linezolid resistance in coagulase-negative staphylococci has become an important matter of concern and mandates stricter control over the use of this antibiotic in order to preserve its clinical utility. © Springer-Verlag 2011.

Background and Purpose.The SEDAN score is a prediction rule for assessment of the risk of symptomatic intracerebral hemorrhage (SICH) per the European Cooperative Acute Stroke Study (ECASS) II definition in patients with acute ischemic stroke treated with intravenous thrombolysis. We assessed the performance of the score in predicting SICH per the ECASS II and Safe Implementation of Treatments in Stroke Monitoring Study (SITS-MOST) definitions in the SITS.International Stroke Thrombolysis Register (SITS-ISTR). Methods.We calculated the SEDAN score in 34 251 patients with complete data, enrolled into the SITS-ISTR. The risk for SICH by both definitions was calculated per score category. Odds ratios for SICH per point increase of the score were obtained using logistic regression. The predictive performance was assessed using area under the curve of the receiver operating characteristic (AUC-ROC). Results.The predictive capability for SICH per ECASS II was moderate at AUC-ROC=0.66. With rising scores, there was a moderate increase in risk for SICH per ECASS II (odds ratio, 1.65 per point; 95% confidence interval,; P<0.001), with SICH rates between 1.6% for 0 points and 16.9% for.5 points, average 5.1%. The predictive capability for SICH per SITS.MOST was weaker, AUC-ROC=0.60, with lower increase per score point (odds ratio, 1.36 per point; 95% confidence interval,; P<0.001), and SICH rates between 0.8% for 0 points and 5.4% for.5 points, average 1.8%. Conclusions.In this very large data set, the predictive and discriminatory performances of the SEDAN score were only moderate for SICH per ECASS II and low for SICH per SITS.Monitoring Study. © 2013 American Heart Association, Inc.

Revision after failed femoral components may be technically demanding due to loss of periprosthetic bone. This retrospective study evaluated the long-term results of femoral revision using the cementless Wagner Self-Locking stem. Between 1992 and 1998, 68 consecutive hips in 66 patients underwent femoral revision using this implant. A total of 25 patients died from unrelated causes without further revision; the remaining 41 hips in 41 patients (12 men and 29 women) with a mean age of 61 years (29 to 80) were reviewed at a mean follow-up of 13.9 years (10.4 to 15.8). A transfemoral approach was used in 32 hips. A total of five stems required further revision because of infection in two, progressive subsidence in two and recurrent dislocation in one. Four hips had dislocated and eight stems had subsided ≥ 10 mm. The mean Harris hip score improved from 33 points pre-operatively to 75 points at final follow-up (p < 0.001). In all, 33 stems (91.7%) showed radiological signs of stable bone fixation. The cumulative survival rates at 15.8 years with femoral revision for any reason and for stem failure as the endpoints were 92.0% (95% confidence interval (CI) 86.0% to 98.4%) and 96.6% (95% CI 92.2% to 100%), respectively. The survivorship with revision and ≥ 10 mm migration of the stem as the endpoint was 83.6% (95% CI 76.6% to 91.4%). This study shows quite good survival and moderate clinical outcome when using a monoblock tapered titanium stem for supporting the regeneration of bone in complex revision hip surgery. © 2011 British Editorial Society of Bone and Joint Surgery.

Introduction The results and causes of failure for 61 patients undergoing surgery for femoral hip periprosthetic fracture are reported.Materials and methods Fractures were classified according to the Vancouver System. Osteosynthesis was performed in 88% of cases and prosthetic revision in 12% of cases. Clinical and functional outcomes were assessed according to the Harris Hip Score and radiological results were evaluated using Beals and Tower's criteria.Results At a mean follow-up of 32 months, the Harris Hip Score was 73.1 and the radiological results were excellent-to-good in 72.2% of patients after the first surgery. At the end of treatment, complete healing of the fracture and stability of the prosthesis was found in 87.3% of patients. The most relevant result was the recovery of walking in 73.8% of patients. Mortality after surgery was 1.6% at 3 months and 3.3% at 12 months. A higher mortality rate occurred when surgery was delayed more than 5 days after trauma.Conclusions The analysis of our cases shows that in Vancouver type B1 fractures treated with plating osteosynthesis, there were worse outcomes in total hip arthroplasty with cemented stems compared with uncemented stems. In Vancouver type B2 fractures with cementless straight stems, osteosynthesis with a plate can be a valid option. In Vancouver type C fractures, the stability of the stem must be carefully assessed. © 2014 Elsevier Ltd. All rights reserved.

Growth hormone (GH) treatment is approved by the US Food and Drug Administration (FDA) not only for GH deficiency (GHD) but also for other childhood growth disorders with growth failure and/or short stature. GHD is the most frequent endocrine disorder presenting with short stature in childhood. During neonatal period, metabolic effects due to congenital GHD require a prompt replacement therapy to avoid possible life-threatening complications. In childhood and adolescence, growth impairment is the most evident effect of GHD and early treatment has the aim of restore normal growth and to reach normal adult height. We reassume in this review the conditions causing GHD and the diagnostic challenge to reach an early diagnosis, and an early treatment, necessary to obtain the best results. Finally, we summarize results obtained in clinical studies about pediatric patients with GHD treated at an early age, in which a marked early catch-up growth and a normalization of adult height were obtained.

The incidence and severity of heterotopic ossification (HO) in two homogeneous groups of patients that received surface replacement arthroplasty (SRA) and conventional total hip arthroplasty (THA) were evaluated retrospectively. Thirty-nine patients undergoing 42 hip resurfacing procedures and 41 primary cementless THAs through an anterolateral approach received a 10-day course of 150 mg/die of indomethacin postoperatively. The median surgical time was 190 minutes and 156 minutes, respectively (P < 0.003). At a minimum 1-year followup, the development of HO was assessed on standard X-ray using Brooker grading. Ectopic bone formation was detected in five cases (11.9%, two Brooker grade I and three grade II) in the SRA group and in 14 hips (34.1%, 12 grade I and two grade II) treated with conventional THA, but the difference was not significant (P < 0.11). No clinically relevant periprosthetic ossification (Brooker III or IV) occurred in both groups. Although the difference was not statistically significant, the incidence of HO after SRA was lower than conventional THA. More extensive soft tissue trauma, bone debris, and longer operative time in hip resurfacing are not likely to be absolute risk factors for HO. Further investigations including larger patient populations are needed to confirm these findings. © 2013 Dario Regis et al.

Obstructive sleep apnea (OSA) is a chronic disease characterized by repetitive partial or complete closure of the upper airway during sleep. OSA tends to be associated with components of metabolic syndrome sharing a common ground of metabolic changes with metabolic syndrome itself. Recent studies showed that subjects with OSA were 6-9 times more likely to have metabolic syndrome than subjects without OSA. Intermittent hypoxia and sleep fragmentation in OSA can initiate intermediary mechanisms (oxidative stress, neurohumoral changes, inflammation) leading to the components of metabolic syndrome. OSA has been suggested to be a novel risk factor, inside the metabolic syndrome, contributing to increased cardiovascular risk. Several studies report that continuous positive airway pressure (CPAP) treatment can reverse pathophysiological changes in OSA, increasing insulin sensitivity and reducing blood pressure. Recent evidences show that CPAP treatment reduces the risk of cardiovascular events and mortality in subjects with OSA. Some subjects with metabolic syndrome can be affected by undiagnosed OSA: CPAP treatment could significantly reduce cardiovascular risk in this subgroup of patients. © 2010 AIM Publishing Srl.
