BACKGROUND Two clinical trials have shown that users of 5α-reductase inhibitors finasteride and dutasteride (5-ARIs) have reduced overall prostate cancer risk, while the proportion of high-grade tumors is increased. We studied tumor characteristics, risk of biochemical recurrence and mortality after radical prostatectomy in 5-ARI and alpha-blocker users. METHODS The study cohort consisted of 1,315 men who underwent radical prostatectomy at the Tampere University Hospital during 1995-2009. Biochemical relapse was defined as serum PSA ≥ 0.2 ng/ml after the operation. Information on mortality and medication purchases was obtained from national registries. Cox proportional regression was used to analyze hazard ratios (HRs) and 95% confidence intervals (95% CI) of biochemical relapse and death. RESULTS The proportion of high-grade (Gleason 7-10) tumors was significantly elevated among men who had used 5-ARIs for 4 years or longer compared to the non-users (83.3% vs. 53.3%, respectively). Survival curves for biochemical relapse-free survival differed between long-term and short-term 5-ARI users, but the hazard ratio remained statistically non-significant. Risk of biochemical recurrence was elevated among alpha-blocker users (HR 1.68, 95% CI 1.37-2.06), but in sensitivity analyses this was evident only in men using alpha-blockers after prostatectomy. Mortality was not associated with medication usage. CONCLUSIONS Long-term users of finasteride or dutasteride had more often high-grade prostate cancer. Our results suggest also worse progression-free survival. The association between risk of biochemical recurrence and post-operative alpha-blocker usage suggests that voiding or storage symptoms after prostatectomy may predict biochemical relapse.

Background: Arthroscopic partial meniscectomy is one of the most common orthopedic procedures, yet rigorous evidence of its efficacy is lacking. Methods: We conducted a multicenter, randomized, double-blind, sham-controlled trial in 146 patients 35 to 65 years of age who had knee symptoms consistent with a degenerative medial meniscus tear and no knee osteoarthritis. Patients were randomly assigned to arthroscopic partial meniscectomy or sham surgery. The primary outcomes were changes in the Lysholm and Western Ontario Meniscal Evaluation Tool (WOMET) scores (each ranging from 0 to 100, with lower scores indicating more severe symptoms) and in knee pain after exercise (rated on a scale from 0 to 10, with 0 denoting no pain) at 12 months after the procedure. Results: In the intention-to-treat analysis, there were no significant between-group differences in the change from baseline to 12 months in any primary outcome. The mean changes (improvements) in the primary outcome measures were as follows: Lysholm score, 21.7 points in the partial-meniscectomy group as compared with 23.3 points in the sham-surgery group (between-group difference, -1.6 points; 95% confidence interval [CI], -7.2 to 4.0); WOMET score, 24.6 and 27.1 points, respectively (between-group difference, -2.5 points; 95% CI, -9.2 to 4.1); and score for knee pain after exercise, 3.1 and 3.3 points, respectively (between-group difference, -0.1; 95% CI, -0.9 to 0.7). There were no significant differences between groups in the number of patients who required subsequent knee surgery (two in the partialmeniscectomy group and five in the sham-surgery group) or serious adverse events (one and zero, respectively). Conclusions: In this trial involving patients without knee osteoarthritis but with symptoms of a degenerative medial meniscus tear, the outcomes after arthroscopic partial meniscectomy were no better than those after a sham surgical procedure.

Background: Rapid etiological diagnosis of a respiratory virus infection may have impact on antiviral and antibiotic therapy, patient cohorting, and prediction of the clinical course. Most point-of-care tests for detection of respiratory viruses have limitations in diagnostic performance and clinical usability. A novel, multianalyte point-of-care antigen detection test system (mariPOC®; ArcDia International Oy Ltd., Turku, Finland) detects eight respiratory viruses (influenza A and B viruses, respiratory syncytial virus (RSV), adenovirus, human metapneumovirus, and parainfluenza type 1, 2, and 3 viruses) from a single nasopharyngeal swab specimen by a fully automated, random-access immunoassay method. Objectives: To evaluate mariPOC® point-of-care test system in comparison with reverse transcription polymerase chain reaction (RT-PCR) in a pediatric emergency department setting. Study design: Prospectively collected samples from 158 children (mean age, 1.8 years) with respiratory symptoms and/or fever were analyzed both by mariPOC® and by multiplex RT-PCR. Results: The sensitivities and specificities (95% confidence intervals) of the mariPOC® test were for influenza A (n=7), 71% (38-100) and 100%; influenza B (n=22), 86% (72-100) and 98% (95-100); RSV (n=35), 89% (78-99) and 100%; adenovirus (n=12), 25% (1-50) and 97% (95-99); and for human metapneumovirus (n=8), 50% (15-85) and 100%, respectively. Parainfluenzaviruses were detected only in five patients. Conclusions: This novel point-of-care test system is a rapid, practical, and specific method for simultaneous detection of eight respiratory viruses. Compared with RT-PCR, its sensitivity is moderately high for detection of RSV and influenza viruses, and low for adenovirus. © 2013 Elsevier B.V.

Background Midurethral slings have become the most preferred surgical treatment for female urinary incontinence. Objective To compare the efficacy and safety of two midurethral sling procedures with a different technique of sling insertion 5 yr after intervention. Design, setting, and participants Multicenter randomized clinical trial conducted in seven public hospitals in Finland including primary cases of stress urinary incontinence. Intervention Surgical treatment with the retropubic tension-free vaginal tape (TVT) procedure or the transobturator tension-free vaginal tape (TVT-O) procedure. Outcome measurements and statistical analysis Objective treatment success criteria were a negative stress test, a negative 24-h pad test, and no retreatment for stress incontinence. Patient satisfaction was assessed by condition-specific quality-of-life questionnaires. Results and limitations A total of 95% of the included women could be assessed according to the protocol 5 yr after surgery. The objective cure rate was 84.7% in the TVT group and 86.2% in the TVT-O group, with no statistical difference between the groups. Subjective treatment satisfaction was 94.2% in the TVT group and 91.7% in the TVT-O group, with no difference between groups. Complication rates were low, with no difference between groups. Conclusions Both objective and subjective cure rates were >80% in both groups even when women lost to follow-up were included as failures. The complication rates were low, with no difference between the groups. No late-onset adverse effects of the tape material were seen. Patient summary Female urinary stress incontinence can be treated surgically with minimally invasive midurethral sling procedures. Two main approaches of sling placement have been developed: the retropubic and the transobturatory. We compared both approaches and followed the patients for 5 yr. We found no difference in cure rate between the procedures, and patient satisfaction was high. Trial registration ClinicalTrials.gov identifier NCT00379314. © 2014 European Association of Urology.

Aims New evidence about first-line radiofrequency catheter ablation (RFA) in symptomatic atrial fibrillation (AF) has emerged. In a single study the comparative treatment effect is potentially diminished by the high rate of cross-over to the alternative therapy. Therefore, we conducted a systematic review and meta-analysis of the available data to further evaluate the efficacy and safety of RFA vs. antiarrhythmic drugs (AADs). Methods and results Five databases were searched for randomized controlled trials comparing RFA and AAD therapy as first-line treatment of AF in August 2014. Three studies with 491 patients with recurrent symptomatic AF were included. The patients were relatively young and the majority of them had paroxysmal AF (98.7%) and no major comorbidity. Radiofrequency catheter ablation was associated with significantly higher freedom from AF recurrence compared with AAD therapy [risk ratio (RR) 0.63, 95% confidence interval (CI) 0.44-0.92, P = 0.02]. The difference in the rate of symptomatic AF recurrences was not statistically significant (RR 0.57, 95% CI 0.30-1.08, P = 0.09). There was one procedure-related death and seven tamponades with RFA, whereas symptomatic bradycardia was more frequent with AAD therapy. Conclusion Radiofrequency catheter ablation seems to be more effective than medical therapy as first-line treatment of paroxysmal AF in relatively young and otherwise healthy patients, but may also cause more severe adverse effects. These findings support the use of RFA as first-line therapy in selected patients, who understand the benefits and risks of the procedure. © Published on behalf of the European Society of Cardiology.

Background We have shown that salt chamber treatment reduces airway hyper-responsiveness as an add-on therapy in adult asthmatics on inhaled corticosteroids. Methods We assessed whether this effect is due to the suppression of eosinophilic airway inflammation. Thirty-nine adult asthmatics on inhaled corticosteroids were randomized to receive active salt chamber treatment with low-salt treatment 6.6 mg/m3 (n = 14), high-salt treatment 10.8 mg/m3 (n = 15) or placebo 0.3 mg/m3 (n = 10) 10 times in a 2 weeks' period in a double-blind manner. Results The level of induced sputum eosinophilic cationic protein μg/l, was 3070 before and 4651 after the low-salt treatment period, on average. In the high-salt treatment group, it was 12 192 μg/l vs 11 803 and in the placebo group 3942 vs 4144, respectively. Salt chamber treatment had no effect on sputum eosinophil or neutrophil cell numbers. Conclusions The reduction in hyper-responsiveness observed in the previous study is probably not due to the effect on eosinophilic inflammation. © 2012 John Wiley & Sons A/S.

A meta-analysis of possible antihypertensive effects of small doses of bioactive tripeptides isoleucine-proline-proline and valine-proline-proline in commercial milk products or tablets was carried out. A random effects model was used on 19 randomized, placebo-controlled clinical intervention trials (published 1996-October 2010) consisting of about 1500 prehypertensive or mildly hypertensive subjects.The overall blood pressure lowering for systolic blood pressure was -4.0 mmHg (95% CI -5.9 to -2.1 mmHg, P < 0.001) and for diastolic blood pressure -1.9 mmHg (95% CI -3.1 to -0.8 mmHg, P < 0.001). However, a positive effect was not reported in all the studies. The results suggest that rather small daily doses of the lactotripeptides in different functional food products may offer a valuable option as a non-pharmacological treatment of prehypertension or mild hypertension as part of life-style advice. © 2013 Informa UK, Ltd.

Background: Increased ferritin concentrations are associated with metabolic syndrome (MetS). The association between ferritin as well as hemoglobin level and individual MetS components is unclear. Erythropoietin levels in subjects with MetS have not been determined previously. The aim of this study was to compare serum erythropoietin, ferritin, haptoglobin, hemoglobin, and transferrin receptor (sTFR) levels between subjects with and without MetS and subjects with individual MetS components.Methods: A population based cross-sectional study of 766 Caucasian, middle-aged subjects (341 men and 425 women) from five age groups born in Pieksämäki, Finland who were invited to a health check-up in 2004 with no exclusion criteria. Laboratory analyzes of blood samples collected in 2004 were done during year 2010. MetS was defined by National Cholesterol Education Program criteria.Results: 159 (53%) men and 170 (40%) women of study population met MetS criteria. Hemoglobin and ferritin levels as well as erythropoietin and haptoglobin levels were higher in subjects with MetS (p < 0.001, p = 0.018). sTFR level did not differ significantly between subjects with or without MetS. Hemoglobin level was significantly higher in subjects with any of the MetS components (p < 0.001, p = 0.002). Ferritin level was significantly higher in subjects with abdominal obesity or high TG or elevated glucose or low high density cholesterol component (p < 0.001, p = 0.002, p = 0.02). Erythropoietin level was significantly higher in subjects with abdominal obesity component (p = 0.015) but did not differ significantly between subjects with or without other MetS components. Haptoglobin level was significantly higher in subjects with blood pressure or elevated glucose component o MetS (p = 0.028, p = 0.025).Conclusion: Subjects with MetS have elevated hemoglobin, ferritin, erythropoietin and haptoglobin concentrations. Higher hemoglobin levels are related to all components of MetS. Higher ferritin levels associate with TG, abdominal obesity, elevated glucose or low high density cholesterol. Haptoglobin levels associate with blood pressure or elevated glucose. However, erythropoietin levels are related only with abdominal obesity. Higher serum erythropoietin concentrations may suggest underlying adipose tissue hypoxemia in MetS. © 2012 Hämäläinen et al.; licensee BioMed Central Ltd.

Background Dermatitis herpetiformis (DH) is an external manifestation of coeliac disease presenting with blistering rash and pathognomonic cutaneous IgA deposits. Better knowledge of subclinical forms and serological testing has resulted in a sharp increase in the incidence and prevalence of coeliac disease. Objectives To investigate the prevalence of DH and analyse whether the incidence of DH changed when the occurrence of coeliac disease increased. Methods All 477 patients with DH diagnosed from 1970 onwards at the Tampere University Hospital were analysed for prevalence in 2009. The incidence of DH was calculated in three 10-year periods from the year 1980. Results The prevalence of DH was 75·3 per 100 000 which is eight times lower than the prevalence of coeliac disease in our area. The annual incidence of DH in the whole period was 3·5 per 100 000, and in the three 10-year periods 5·2, 2·9 and 2·7 per 100 000, respectively. The decrease in incidence between the first and second 10-year period was significant (P < 0·001). The male to female ratio of DH was 1·1: 1. The mean age at diagnosis increased significantly during the study, in men from 35·3 to 51·1 years and in women from 36·3 to 45·8 years. Conclusions The present study shows the highest prevalence of DH reported to date. Although the overall incidence of DH was also high, a significant decrease occurred in the 1990s, which is in contrast to the incidence of coeliac disease. © 2011 British Association of Dermatologists.

We assessed morphology and ERα protein and gene expression of two breast cancer cell lines after three different fixatives: neutral-buffered 10% formaldehyde, LN-FIX and FineFIX and varying fixation times. We found that the cell morphology was best preserved in cells fixed with LN-FIX. Two commercial fixatives used in this study shrank cells less than formalin. In immunohistochemical assay samples were stained with two different ERα antibodies, clone 1D5 and clone SP1. All tested fixatives were suitable for immunohistochemistry. Staining was more intensive and the number of stained cells was larger with the clone 1D5 than with the clone SP1. Our gene expression analysis showed that formalin and LN-FIX preserve the ERα better than FineFIX, which is advertised to be optimal for molecular analysis. Our study suggests that tissues fixed with formalin are suitable also for molecular biology assays. This makes possible to research formalin-fixed paraffin-embedded archival tissues also with molecular techniques. © 2009 Elsevier Inc.
