AIMS The pathophysiological mechanism of incontinence is multifactorial. We evaluated the role of 3D-4D ultrasound in the assessment of the fascial supports of the urethra and the urethral sphincter complex (USC) for diagnosing stress urinary incontinence. METHODS Observational case-control study in women with and without stress urinary incontinence attending a urogynecology service and a general gynecology service. All women were interviewed, examined, and classified according to the Pelvic Organ Prolapse Quantification (POP-Q) and underwent a 3D-4D translabial ultrasound. Fascial supports of the urethra were assessed by tomographic ultrasound and were considered to be intact or absent if it was possible to identify them at eight levels on each side, urethral mobility was assessed on maximal Valsalva in sagittal section and the length and volume of the USC at rest and on maximal Valsalva were determined using the Virtual Organ Computer-aided Analysis (VOCAL) program. Variables were compared between continent and incontinent women. RESULTS A total of 173 women were examined, 78 continent and 95 incontinent. There was a significant difference in urethral mobility between continent and incontinent women (12.82 mm vs. 21.85 mm, P

To describe the characteristics of patients with Behçet's disease (BD) who presented with venous thrombosis. In addition, we identified the factors associated with this venous involvement and those related with recurrent venous thrombosis.Up to January 2015, 544 BD patients from 20 Spanish hospitals had been included in the REGEB (REGistro de la Enfermedad de Behçet as Spanish nomenclature). We selected those patients who presented venous thrombosis. Descriptive analysis was performed and factors related with venous thrombosis were identified.Overall, 99 (18.2%) BD patients had vascular thrombosis, 91 (16.7%) of them (16.7%) involving venous vessels and 18 (19.7%) suffered from venous thrombotic relapse. Lower limbs were the most common location of deep venous thrombosis present in up to 60% of patients. In 12 (13.2%) patients, venous thrombosis affected two vascular territories simultaneously and in 6 (6.6%) the venous and arterial involvement coincided in time. Overall, at the diagnosis of venous thrombosis, 97.6% of patients presented concomitantly other clinical symptoms attributable to BD. In logistic regression multivariate analysis factors associated to venous thrombosis were male sex (Odds ratio [OR] 4.3, 95% confidence interval [CI] 2.5-7.7), erythema nodosum (OR 2.4, 95%CI 1.4-4.1), fever (OR 2.0, 95%CI 1.1-3.8), and central nervous system (CNS) involvement (OR 2.5, 95%CI 1.3-4.8). Considering relapses, CNS involvement was an independent risk factor according logistic regression. However, Cox multivariate analysis did not confirm this finding.We identified factors related with venous involvement in patients included in the REGEB cohort.

To assess the clinical manifestations and prognosis of Spanish patients with systemic sclerosis (SSc) according to their immunological profile.From the Spanish Scleroderma Study Group or RESCLE (Registro de ESCLErodermia as Spanish nomenclature) Registry we selected those patients in which anti-centromere (ACA), anti-topoisomerase I (ATA), and anti-RNA polymerase III (ARA) antibodies had been determined, and a single positivity for each SSc specific antibody was detected. Demographic, clinical, laboratory, and survival data were compared according to the serologic status of these antibodies.Overall, 209 SSc patients were included. In 128 (61%) patients ACA was the only positive antibody, 46 (22%) were only positive for ATA, and 35 (17%) for ARA. Of note, the three groups were mutually exclusive. In univariate analysis, patients with ACA presented more frequently limited cutaneous SSc (lcSSc) (p0.001), whereas diffuse cutaneous SSc (dcSSc) was the most frequent subtype in patients with ATA (54%) and ARA (62%) (both p0.001). Positive patients for ARA showed the highest prevalence of joint involvement (p0.001) and those from ATA group had a higher prevalence of interstitial lung disease (ILD) (p0.001). Scleroderma renal crisis was more frequent in the ARA group (p0.001). In multivariate analysis, ACA were associated with female gender and were protective for dcSSc and ILD. ATA were found to be protective for lcSSc and they were independently associated with interstitial reticular pattern. ARA positivity was independently associated with dcSSc. We did not find differences in mortality between the three groups.In Spanish SSc patients, the presence of SSc specific antibodies conferred a distinctive clinical profile.

Aims To analyze whether episiotomy affects the urogenital hiatal area and the difference in the hiatus at rest and during contraction, as an indirect measurement of the contractile capacity of the levator ani muscle. Methods We performed an observational, comparative, retrospective study of primiparous women who had normal vaginal deliveries. The urogenital hiatal area was compared in women with and without episiotomy. All women underwent transperineal ultrasound scanning after delivery, and all the images were analyzed offline by the principal investigator who was blinded to all clinical data. The urogenital hiatal area was measured at rest and during both Valsalva and contraction manoeuvres. The difference in the hiatus at rest and during contraction was also calculated. These scanning variables were compared between the study groups. Results In total, 194 women were analysed (101 with, and 93 without, episiotomy). There were no statistically significant differences between the groups regarding the area of the hiatus at rest (P = 0.583), on Valsalva (P = 0.158), and on contraction (P = 0.468), or in the difference in the hiatus at rest and during contraction (P = 0.095). Conclusions In normal vaginal delivery, neither the area of the urogenital hiatus nor its difference at rest and during contraction, as measured by ultrasound, were modified by performing an episiotomy.

The functional variant R620W of the protein tyrosine phosphatase non receptor-22 (PTPN22) gene plays an important role in susceptibility to several immuno-mediated pathologies. Behçet's disease (BD) is a complex disease related to the immune system with a demonstrated genetic base. The HLA class I genes are the most important genetic factors in BD although other genes are also involved in the susceptibility to this disease. The PTPN22 has been proposed as a candidate gene in BD but this association has not been clearly demonstrated yet. The aim of this study was to assess the association of PTPN22 with BD.A cohort composed of 404 Spanish BD patients and 1517 unrelated healthy individuals ethnically matched was genotyped in rs2476601 (R620W). Five tag SNPs: rs1217412, rs2476599, rs3789607, rs3765598 and rs1217419 (spanning a 57 Kb region between 3'UTR and 5'UTR) and rs2488457 (located at the promoter region) were also studied in order to perform a screening of the complete gene. Genotyping was performed using TaqMan® assays. The rs2476601 data were included in a meta-analysis together with those published till the date. The rest of SNPs were used in a case-control study.No evidence of the association of rs2476601 with BD in the meta-analysis (P = 0.504 in the model of alleles) was found. In the case-control study, no statistically significant differences were observed when comparing the distribution of variants in patients and controls.Our results do not support a major role of the PTPN22 gene in BD.

Behçet's disease (BD) is an immune-mediated and complex disease associated with HLA class I and other genes. The aim of this study was to contribute to a better understanding of the relationship of the 32-bp deletion in the CCR5 gene (CCR5Δ32) and this disease by conducting a case-control study in the Spanish population and also a meta-analysis including all the studies available to date.A cohort composed of 348 BD Spanish patients and 477 unrelated healthy and ethnically matched individuals were genotyped in CCR5Δ32 using polymerase chain reaction (PCR) and capillary electrophoresis with fluorescent detection. In the meta-analysis, data from a total of seven populations extracted from four previous studies along with data of the present study were included.Regarding the case-control study, no statistically significant differences were observed when the patient and control groups were compared (allelic model: 0.07 in patients vs. 0.06 in controls, p=0.303). In the meta-analysis, no evidence of association of the CCR5Δ32 polymorphism with BD was observed (pMH=0.091; OR=1.22; 95%CI 0.98 to 1.52 in the allelic model).The results of this meta-analysis discard a major role of the CCR5Δ32 polymorphism in BD.

Behçet's disease (BD) is an immune-mediated and complex disease which has been associated with HLA class I molecules although other genes such as IL23R and IL10 have also been involved in the susceptibility to BD. Recently, an association of variants of the JAK1 and TNFAIP3 genes with the disease has been reported in the Chinese Han population. The aim of the present work was to asses whether the association described in Asian populations is replicated in Europeans.This study includes a total of 1155 Spanish subjects of European origin (372 BD and 783 unrelated healthy individuals). Patients were recruited from different hospitals and controls were collected in the same geographic regions and they matched with patients in age and gender. A total of five SNPs, two in the JAK1 gene: rs2780815 and rs310241 and the other three in the TNFAIP3: rs10499194, rs9494885 and rs610604, were included in this study. The genotyping of these SNPs was performed using a real time PCR system (TaqMan® SNP Genotyping Assays).No statistically significant differences were found when the patient and control groups were compared. The distribution of the risk alleles was similar in patients with and without eye manifestations and in patients with and without HLA-B*51.The association of variants of the genes JAK1 and the TNFAIP3 with BD which has been described in the Chinese population was not replicated in Europeans.
