Purpose: Non-diagnostic results still hinder the routine use of core biopsy (CB) and fine needle aspiration (FNA) in the diagnostic process of renal tumours. Furthermore, substantial interobserver variability has been reported. We assessed the added value of combining the results of CB and FNA by five pathologists in the ex vivo diagnosis of renal mass. Methods: Two ex vivo core biopsies were taken followed by two FNA passes from extirpated tumours. All samples were evaluated by five blinded pathologists. A consensus diagnosis of the surgical specimen was the index for comparison. For each pathologist, the number of non-diagnostic (non-conclusive or undetermined biology and failed biopsies), correct and incorrect scored cases of each technique was assessed. When a non-diagnostic CB or FNA had a correct diagnostic counterpart, this was considered as of added value. Results: Of the 57 assessed tumours, 53 were malignant. CB was non-diagnostic in 4-10 cases (7-17.5%). FNA established the correct diagnosis in 1-7 of these cases. FNA was non-diagnostic in 2-6 cases (3.5-10.5%), and the counterpart CB established the correct diagnosis in 1-6 of these cases. For the 5 pathologists, accuracy of CB and FNA varied between 82.5-93% and 89.5-96.5%, respectively. Combination of both types of biopsy resulted in 55-57 correct results (accuracy 96.5-100%), i.e., an increase in accuracy of 3.5-14%. Conclusion: Combining the result of CB and FNA in renal mass biopsy leads to a higher diagnostic accuracy. Recommendations on which technique used should be adapted to local expertise and logistic possibilities. © 2011 The Author(s). Source

Objective: To investigate the presence of synovitis, tenosynovitis and enthesitis with power Doppler (PD) ultrasonography (US) in patients with psoriasis without musculoskeletal diseases as compared with controls with other skin diseases without musculoskeletal disorders. Methods: A total of 162 patients with plaque psoriasis and 60 age-matched controls with other skin diseases, all without musculoskeletal diseases, were prospectively recruited at 14 centres. They underwent dermatological and rheumatological assessment and a blinded PDUS evaluation. Clinical assessment included demographics, comorbidities, severity of psoriasis, work and sport activities and musculoskeletal clinical examination. PDUS evaluation consisted of the detection of grey scale (GS) synovitis and synovial PD signal in 36 joints, GS tenosynovitis and tenosynovial PD signal at 22 sites, and GS enthesopathy and entheseal PD signal in 18 entheses. Results: US synovitis and enthesopathy were significantly more frequent in psoriatic patients than in controls (P = 0.024 and 0.005, respectively). The percentage of joints with US synovitis was 3.2% in the psoriasis group and 1.3% in the control group (P<0.0005). US enthesopathy was present in 11.6% of entheses in the psoriasis group and 5.3% of entheses in the control group (P<0.0005). Entheseal PD signal was found in 10 (7.4%) psoriatic patients, whereas no controls showed this finding (P = 0.05). Among demographic and clinical data, having psoriasis was the only significant predictive variable of the presence of US synovitis [odds ratio (OR) 2.1; P = 0.007] and enthesopathy (OR 2.6; P = 0.027). Conclusion. Psoriatic patients showed a significant prevalence of asymptomatic US synovitis and enthesopathy, which may indicate a subclinical musculoskeletal involvement. © The Author 2011.

TMPRSS2-ERG rearrangement is a genetic alteration exclusive to prostate cancer, associated with taxane resistance in preclinical models. Its detection in blood samples of metastatic resistant prostate cancer (mCRPC) patients may indicate the presence of circulating tumour cells with this genetic alteration and may predict taxane resistance. To test this hypothesis, we evaluated TMPRSS2-ERG expression using quantitative reverse transcription polymerase chain reaction in peripheral blood mononuclear cells and tumour tissue from mCPRC patients treated with taxanes. We examined peripheral blood mononuclear cells from 24 healthy controls, 50 patients treated with docetaxel, and 22 with cabazitaxel. TMPRSS2-ERG was detected in 0%, 16%, and 22.7% of them, respectively. In docetaxel-treated patients TMPRSS2-ERG detection correlated with lower prostatic-specific antigen (PSA) response rate (12.5% vs 68.3%, p = 0.005), PSA-progression-free survival (PFS; 3.1 mo vs 7.5 mo, p <. 0.001), clinical/radiological-PFS (3.1 mo vs 8.2 mo, p <. 0.001), and it was independently associated with PSA-PFS (hazard ratio 3.7; p = 0.009) and clinical/radiological-PFS (hazard ratio 6.3; p <. 0.001). Moreover, TMPRSS2-ERG also predicted low PSA-PFS to cabazitaxel. At progression, a switch from negative to positive TMPRSS2-ERG was observed in 41% of patients with undetected TMPRSS2-ERG at the baseline sample. Tissue TMPRSS2-ERG expression correlated with lower PSA-PFS (p = 0.02) to docetaxel. Our findings support the potential role of TMPRSS2-ERG detection as a biomarker to tailor treatment strategies. Patient summary: Taxanes are the most active chemotherapy agents in metastatic resistant prostate cancer. However, not all patients respond to this therapy. In the present study we show that the detection of TMPRSS2-ERG in blood from metastatic resistant prostate cancer patients predicts resistance to docetaxel and it may be useful to select treatment and to avoid possible toxicities in refractory patients. TMPRSS2-ERG is a genetic alteration specific of prostate cancer that has been linked to taxane resistance in preclinical models of castration-resistant prostate cancer. TMPRSS2-ERG expression detection in the peripheral blood of metastatic castration-resistant prostate cancer patients correlates with docetaxel resistance. © 2016 European Association of Urology.

Background Patient safety is a major concern worldwide, but particularly high rates of adverse events are reported in the surgery setting. Angiology and vascular surgery is of special interest due to the complexity of the pathologies involved and the esthetic component of some of its procedures. In this study we identified the most frequent factors that apply to vascular surgery claims to determine areas of special risk in vascular surgery, with an aim to improve patient safety. Methods We performed a retrospective and descriptive study of the claims pertaining to vascular surgery from the database of the Service of Professional Liability (SRP) of the Official College of Physicians of Barcelona. The time frame of data collection was from 1986 to 2009. We analyzed both the clinical and legal characteristics of the cases. Results Of the total of 6952 registered claims during the 23-year period, 91 (1.3%) were related to the practice of vascular surgery. Of these, 53.8% were related to venous pathology and 46.1% to arterial pathology. Neurologic damage was the main motive for claims (15.3%), followed by thromboembolic disease (14.2%), burns as a result of cosmetic treatment (12%), and amputation (10.9%). The neurologic damage in relation to vein pathology registered the greatest proportion of cases with professional liability (30.8%), followed by burns (19.2%), forgotten gauze (11.5%), and amputations (11.5%). Conclusions Angiology and vascular surgery does not seem to be a specialty with a high risk for claims, but complications, such as thromboembolic disease and neurologic damage after varicose vein intervention, do occur and deserve special attention so improvements can be made to patient safety. © 2014 Elsevier Inc.

Background: Both the safety and efficacy of biologic therapy may be affected in the presence of highly prevalent chronic viral hepatitis. Objectives To evaluate the safety and effectiveness of ustekinumab and antitumour necrosis factor therapy in patients with psoriasis and concomitant chronic viral hepatitis. Methods: This was a retrospective, multicentre study. Twenty-five patients with psoriasis and concurrent hepatitis C virus (HCV) (20 patients) or hepatitis B virus (HBV) (five patients) infection who had received at least one biologic agent (etanercept, 21 treatments; adalimumab, four; ustekinumab, four; infliximab, two) were included. Clinical, imaging and laboratory data were recorded. Results: In the case of HCV infection, the majority of the patients did not exhibit increases in their viral load or serum liver tests. Aspartate aminotransferase, alanine aminotransferase and gamma glutamyl transpeptidase were doubled from the baseline measurement in only one patient treated with etanercept. Two other cases exhibited viral load increases during the follow-up period. In total, 18 of the 26 treatments achieved a 75% improvement in their Psoriasis Area and Severity Index (PASI 75) score during the follow-up period. Two patients treated with etanercept were diagnosed with hepatocellular carcinoma. In the case of HBV infection, all of the patients were being treated with antiviral therapy, and none presented significant variations in viral load or serum liver enzymes. All patients achieved a PASI 75 during follow-up. Conclusions: Biologic therapy was effective and safe for the majority of our patients with HCV and HBV infection, although there may be a risk of reactivation or aggravation. We describe the first cases to receive ustekinumab. The use of biologics should be limited to those cases in which the risk-benefit ratio is justified. © 2012 British Association of Dermatologists.
