Absolute basophil count is associated with time to recurrence in patients with high-grade T1 bladder cancer receiving bacillus Calmette-Guérin after transurethral resection of the bladder tumor.

BACKGROUND: Basophils, eosinophils and monocytes may be involved in BCG-induced immune responses and be associated with outcomes of bladder cancer patients receiving intravesical BCG. Our objective was to explore the association of baseline counts of basophils, eosinophils and monocytes with outcomes of patients with high-grade T1 bladder cancer receiving a standard course of intravesical BCG. METHODS: We retrospectively reviewed medical records of patients with primary T1 HG/G3 bladder cancer. After re-TURBT, patients were treated with a 6-week course of intravesical BCG induction followed by intravesical BCG every week for 3 weeks given at 3, 6, 12, 18, 24, 30 and 36 months from initiation of therapy The analysis of potential risk factors for recurrence, muscle invasion and cancer-specific and overall survival was performed using univariable Cox regression models. Those factors that presented, at univariate analysis, an association with the event at a liberal p < 0.1, have been selected for the development of a multivariable model. RESULTS: A total of 1045 patients with primary T1 HG/G3 were included. A total of 678 (64.9%) recurrences, 303 (29.0%) progressions and 150 (14.3%) deaths were observed during follow-up. Multivariate analysis showed that logarithmic transformation of basophils count was associated with a 30% increment in the hazard of recurrence per unit increase of logarithmic basophils count (HR 1.30; 95% confidence interval 1.09-1.54; p = 0.0026). Basophil count modeled by quartiles was also significantly associated with time to recurrence [second vs. lower quartile HR 1.42 (1.12-1.79); p = 0.003, third vs. lower quartile HR 1.26 (1.01-1.57); p = 0.041; upper vs. lower quartile HR 1.36 (1.1-1.68); p = 0.005]. The limitations of a retrospective study are applicable. CONCLUSION: Baseline basophil count may predict recurrence in BCG-treated HG/G3 T1 bladder cancer patients. External validation is warranted.

Ostium Ratio and Neck Ratio Could Predict the Outcome of Sidewall Intracranial Aneurysms Treated with Flow Diverters.

BACKGROUND AND PURPOSE: Incompletely occluded flow diverter treated aneurysms remain at risk of rupture and thromboembolic complications. Our aim was to identify the potential for incomplete occlusion of intracranial aneurysms treated by flow diverters. We investigated whether aneurysm ostium size in relation to parent artery size affects angiographic outcomes of flow diverter-treated sidewall aneurysms. MATERIALS AND METHODS: Flow diverter-treated sidewall aneurysms were divided into "occluded" and "residual" (incomplete occlusion) groups based on 6-month angiographic follow-up. We calculated the ostium ratio, a new parameter defined as the aneurysm ostium surface area versus the circumferential surface area of the parent artery. We also calculated the neck ratio, defined as clinical aneurysm neck diameter versus parent artery diameter from pretreatment 2D DSA, as a 2D surrogate. We compared the performance of these ratios with existing aneurysm morphometrics (size, neck diameter, volume, aspect ratio, size ratio, undulation index, nonsphericity index, ellipticity index, bottleneck factor, aneurysm angle, and parent vessel angle) and flow diverter-related parameters (metal coverage rate and pore density). Statistical tests and receiver operating characteristic analyses were performed to identify significantly different parameters between the 2 groups and test their predictive performances. RESULTS: We included 63 flow diverter-treated aneurysms, 46 occluded and 17 residual. The ostium ratio and neck ratio were significantly higher in the residual group than in the occluded group (P < .001 and P = .02, respectively), whereas all other parameters showed no statistical difference. As discriminating parameters for occlusion, ostium ratio and neck ratio achieved areas under the curve of 0.912 (95% CI, 0.838-0.985) and 0.707 (95% CI, 0.558-0.856), respectively. CONCLUSIONS: High ostium ratios and neck ratios could predict incomplete occlusion of flow diverter-treated sidewall aneurysms. Neck ratio can be easily calculated by interventionists to predict flow-diverter treatment outcomes.

Benign prostatic hyperplasia and intraprostatic inflammation are associated with liver inflammation: it's time for prevention.

Some evidences have supported the link between benign prostatic hyperplasia (BPH)/lower urinary tract symptoms (LUTS) and inflammation. In this study, we aimed to evaluate the association between prostatic inflammation (PI) and non-alcoholic steatohepatitis (NASH) evaluated by a non-invasive scores in a cohort of patients affected by BPH/LUTS. Between January 2012 and January 2016, we conducted a prospective study in a single academic outpatient clinic on 132 consecutive patients who underwent surgery for lower urinary tract symptoms (LUTS) due to bladder outlet obstruction (BOO). A non-invasive non-alcoholic steatohepatitis score (NASH score) was calculated, and PI was evaluated through the Irani score. Patients with a NASH score > 1.05 had an average larger prostate volume (55 vs. 45 cc, p < 0.05), a greater waist circumference (103 vs. 93.5 cm, p < 0.01), and high values of blood glucose, triglycerides, insulin, and BMI compared to patients without NASH; 36% of patients with an Irani score ≥ 4 had NASH compared to 16.1% of patients who had a NASH score < 1.05 (p < 0.05). We found that non-alcoholic steatohepatitis (NASH ≥ 1.05) was an independent risk factor for Irani score ≥4 (OR: 3.24; p < 0.05) and of prostate volume ≥ 40 cc (OR: 13.99; p < 0.01). LUTS/BPH and NASH can be closely related, underlying common triggers of induction. In particular, inflammation seems to be associated with both conditions and with prostate gland overgrowth. Early identification of this class of patients could play a key role in preventing complications related to disease progression.

Compacting a Single Flow Diverter versus Overlapping Flow Diverters for Intracranial Aneurysms: A Computational Study.

BACKGROUND AND PURPOSE: Locally compacting the mesh of a flow diverter by a dynamic push-pull technique can accelerate intracranial aneurysm healing. We asked how this deployment strategy compares with overlapping 2 flow diverters for aneurysmal flow reduction. MATERIALS AND METHODS: Using a high-fidelity virtual stent placement method, we simulated 3 flow-diverter strategies (single noncompacted, 2 overlapped, and single compacted) in 3 aneurysms (fusiform, large saccular, and medium saccular). Computational fluid dynamics analysis provided posttreatment hemodynamic parameters, including time-averaged inflow rate, aneurysm-averaged velocity, wall shear stress, total absolute circulation, and turnover time. We examined the relationship between the achieved degree of compaction and aneurysm orifice area. RESULTS: Flow-diverter compaction resulted in a compaction coverage of 57%, 47%, and 22% over the orifice of the fusiform, large, and medium saccular aneurysm, respectively. Compaction coverage increased linearly with orifice area. In the fusiform aneurysm, the single compacted flow diverter accomplished more aneurysmal flow reduction than the other 2 strategies, as indicated by all 5 hemodynamic parameters. In the 2 saccular aneurysms, the overlapped flow diverters achieved the most flow reduction, followed by the single compacted and the noncompacted flow diverter. CONCLUSIONS: Compacting a single flow diverter can outperform overlapping 2 flow diverters in aneurysmal flow reduction, provided that the compaction produces a mesh denser than 2 overlapped flow diverters and this denser mesh covers a sufficient portion of the aneurysm orifice area, for which we suggest a minimum of 50%. This strategy is most effective for aneurysms with large orifices, especially fusiform aneurysms.

The surgical management of patients with clinical stage T4 bladder cancer: A single institution experience.

INTRODUCTION: Patients with clinical T4 (cT4) bladder cancer (BCa) infrequently undergo radical cystectomy (RC). We investigated the reliability of preoperative clinical staging, perioperative and survival outcomes in patients treated with RC due to cT4a-b BCa disease at a single tertiary care institution. METHODS: The study relied on 917 BCa patients treated with RC and pelvic lymph node dissection (PLND) at a single institution between January 1995 and December 2012. We compared the accuracy of the clinical assessment with final pathology results. Moreover, we evaluated perioperative outcomes, complication rates and survival after surgery. RESULTS: The median follow-up was 62 months. Overall, 74 (8.1%) patients presented cT4 stage at preoperative evaluation. Conversely, a pathological T4 disease was confirmed only in 68.9% patients staged initially as cT4. No differences were recorded in complications, 30 days readmission or 30 days death rates between cT1-T3 vs. cT4a vs. cT4b (p > 0.1). At multivariable Cox regression analyses predicting cancer specific mortality, clinical T4 stage vs. clinical T1-2, clinical T3 stage vs. clinical T1-2 and age were predictors of worst survival after RC (all p < 0.04). CONCLUSIONS: We recorded poor concordance between preoperative imaging and pathology in cT4 patients. No differences in major perioperative outcomes and acceptable survival expectancies were reported in patients treated for cT4 disease.

Gynecomastia in patients with prostate cancer: update on treatment options.

Non-steroidal antiandrogen monotherapy offers potential quality of life benefits over other treatment modalities in patients with prostate cancer. Nevertheless, gynecomastia and breast pain still represent the most bothersome side effects during this treatment. In this update article, recent advances in the management options for gynecomastia/breast pain caused by hormonal manipulation are reviewed and critically analyzed.

Surgical treatment of atrial fibrillation with bipolar radiofrequency ablation: mid-term results in one hundred consecutive patients.

AIM: The Cox-Maze procedure was introduced nearly two decades ago for the surgical treatment of atrial fibrillation (AF). Recently, our group has replaced most of the incisions of the Cox-Maze procedure with bipolar radiofrequency (RF) ablations (Cox-Maze IV procedure). The purpose of this study was to examine our midterm results with the Cox-Maze procedure using bipolar RF ablation. METHODS: From January 2002 to October 2005, 100 consecutive patients underwent a modified Cox-Maze procedure with bipolar RF ablation for AF; 32 were lone operations, and 68 were concomitant procedures. Follow-up was performed at 1, 3, 6, and 12 months, and then annually thereafter. Heart rhythm was confirmed by electrocardiography. RESULTS: The mean age of patients was 62+/-13 years; 57% were male. Duration of AF was 6.3+/-7.6 years (0.1 to 40 years), 59% had paroxysmal AF, and 34% had permanent AF. Follow-up was complete for all patients with a mean follow-up of 13+/-10 months. At 12-month follow-up, 91% (49/54) of patients were free of AF. Cross-clamp time in the lone Cox-Maze IV procedure patients was 42+/-15 minutes, while it was 101+/-29 minutes for the Cox-Maze IV with a concomitant procedure (compared to 93+/-34 minutes and 122+/-37 minutes for the traditional procedure, P<0.05). There were four operative deaths. CONCLUSIONS: The Cox-Maze IV procedure had good mid-term efficacy. The use of bipolar RF energy significantly decreased operative time and simplified the procedure compared to the traditional Cox-Maze procedure, potentially increasing utilization of the procedure among cardiac surgeons.

[Antibacterial prophylaxis in endourological procedures]. / La profilassi antibatterica nelle manovre endourologiche.

AIM: Antibiotic prophylaxis for the prevention of postsurgical infections is a common practice in urologic surgery, as well as in endourologic procedures, both in at risk patients (local or systemic risk factors: age, immunological status, metabolic disorders, poor general conditions) or with a positive urine culture, but also in patients with urine previously sterile. As Gram-negative strains are the most common pathogens, it is reasonable to use a quinolone or a beta-lactam. METHODS: One-hundred and thirty-one patients (range 21-89 years) underwent transurethral cystoscopy (52 cases), vesical catheterism (44 cases), extracorporeal shockwave lithotripsy (17 cases) and transrectal prostatic biopsy (18 cases). An antimicrobial prophylaxis with ciprofloxacin 500 mg (22 patients, 16.8%), levofloxacin 500 mg (54 patients, 41.2%) and prulifloxacin 600 mg (55 patients, 42%) was administered. RESULTS: Globally, the incidence of urinary tract infections during 15 days after surgery was 8.4% (11 cases out of 131): ciprofloxacin 9.1%, levofloxacin 11.1% and prulifloxacin 5.5%, respectively. The patients compliance with the prophylactic treatment was good or excellent in 122 cases (93.1%) and poor in 9 cases (6.9%). No major differences between antibiotics used in prophylaxis were detected, keeping into account the limited size of the global population and subgroups defined by the endourological procedures. CONCLUSIONS: Prulifoxacin, with a broad antimicrobial spectrum, favourable pharmacokinetic properties and easy to use, can be considered a valid and well tolerated therapeutic option for the antibacterial prophylaxis in endourological procedures, both in hospital and in outpatient setting.

Long-term sexual outcomes after holmium laser enucleation of the prostate: which patients could benefit the most?

Assess rate and predictors of erectile function (EF) outcomes at long-term follow-up (FU) after holmium laser enucleation of the prostate (HoLEP). Cross-sectional analyses were performed on 135 patients with a mean FU of 12 years post HoLEP. Patients completed both a baseline and a FU International Index of Erectile Function (IIEF)-EF domain and the International Prostatic Symptoms Score (IPSS). Postoperative EF outcomes, including rate and predictors of EF improvement considering minimal clinically important differences (MCIDs) criteria, were assessed. Logistic regression models tested the association between predictors and EF. At a mean (median) FU of 152.1 (163) months, patients showed a significant decrease in the IIEF-EF score P<0.01) and significant IPSS improvement (P<0.01). Overall, 50 (37%) patients worsened by at least one IIEF-EF category. Conversel, 23 (17%) patients reported an improvement in postoperative IIEF-EF score; 75 (55.6%) and 10 (7.4%) patients maintained and eventually improved their IIEF-EF category, respectively. Patients reporting a decrease in the postoperative IIEF-EF score were significantly older (P=0.03) and showed a significantly longer mean FU (P<0.01) than those reporting postoperative improvements of IIEF-EF. Nine (6.7%) patients showed significant EF improvement according to MCIDs criteria. Both higher IPSS scores (odds ratio (OR): 1.12; P=0.02) and lower IIEF-EF (OR: 0.88; P<0.01) at baseline, emerged as independent predictors of postoperative EF improvement. HoLEP was associated with a decrease in EF and a persistent amelioration of BPH-related urinary symptoms at long-term FU. Almost one third of patients worsened by at least one IIEF-EF category. However, a clinically meaningful EF improvement was observed in roughly 7% of the individuals. Patients with more severe preoperative urinary symptoms and ED benefited more from HoLEP in terms of EF.

Patterns and prognostic significance of clinical recurrences after radical cystectomy for bladder cancer: A 20-year single center experience.

OBJECTIVE: Patients treated with radical cystectomy (RC) due to bladder cancer (BCa) face high risk of clinical recurrence. The aim of our study was to describe recurrence patterns and characteristics related to survival in patients treated with RC due to BCa. METHODS: Years 1992-2012 of a prospectively maintained institutional RC registry were queried for clinical localized urothelial BCa patients. Clinical recurrences were categorized as local, distant or secondary urothelial recurrences. Kaplan Meier analysis assessed time to cancer specific mortality (CSM). Multivariable Cox regression models were constructed to predict recurrence and CSM after recurrence. RESULTS: Data from 1110 patients with urothelial non-metastatic BCa at RC were analyzed with 7.5 years of median follow up. Overall, 324 patients experienced recurrence and 200 (61.7%) were single site recurrence. The locations were: 43 local (22 cystectomy bed and 21 pelvic lymph node dissection template), 138 distant (36 lung, 19 liver, 52 bone, 17 extra pelvic LN, 7 peritoneal, 4 brain and 3 others) and 19 secondary urothelial carcinoma (11 upper urinary tract, 8 urethra). Significant independent predictors of overall recurrence were pathological stage pT3/T4 vs. pT0-2, pathological N positive status and positive surgical margin. Median overall survival after recurrence was 18 months. At multivariate analysis, pathological T3 (Hazard ratio [HR]: 1.62), T4 (HR: 1.58), interval from RC to recurrence (HR: 0.92) and distant (HR: 2.57) recurrences were independently associated with CSM (all p < 0.05). CONCLUSIONS: Overall, one out of three patients treated with RC face recurrence during follow up. Early and distant recurrences are associated with shortest survival expectancies.

Metabolic syndrome in white European men presenting for primary couple's infertility: investigation of the clinical and reproductive burden.

Despite complex interactions between obesity, dyslipidemia, hyperinsulinaemia, and the reproductive axis, the impact of metabolic syndrome on human male reproductive function has not been analysed comprehensively. Complete demographic, clinical, and laboratory data from 1337 consecutive primary infertile men were analysed. Health-significant comorbidities were scored with the Charlson Comorbidity Index (categorised 0 vs. 1 vs. 2 or higher). NCEP-ATPIII criteria were used to define metabolic syndrome. Semen analysis values were assessed based on the 2010 World Health Organisation (WHO) reference criteria. Descriptive statistics and logistic regression models tested the association between semen parameters and clinical characteristics and metabolic syndrome. Metabolic syndrome was found in 128 (9.6%) of 1337 men. Patients with metabolic syndrome were older (p < 0.001) and had a greater Charlson Comorbidity Index of 1 or higher (chi-square: 15.6; p < 0.001) compared with those without metabolic syndrome. Metabolic syndrome patients had lower levels of total testosterone (p < 0.001), sex hormone-binding globulin (p = 0.004), inhibin B (p = 0.03), and anti-Müllerian hormone (p = 0.009), and they were hypogonadal at a higher rate (chi-square: 32.0; p < 0.001) than patients without metabolic syndrome. Conversely, the two groups did not differ significantly in further hormonal levels, semen parameters, and rate of either obstructive or non-obstructive azoospermia. At multivariate logistic regression analysis, testicular volume (OR: 0.90; p = 0.002) achieved independent predictor status for WHO pathological semen concentration; conversely, age, Charlson Comorbidity Index scores, metabolic syndrome, and inhibin B values did not. No parameters predicted normal sperm morphology and total progressive motility. Metabolic syndrome accounts for roughly 9% of men presenting for primary couple's infertility. Although metabolic syndrome patients have a lower general male health status, semen analysis values seem independent of the presence of metabolic syndrome.

Adaptation and validation of an Italian version of the Prostate Cancer Specific Quality of Life Instrument (PROSQOLI).

OBJECTIVE: The Prostate Cancer Specific Quality of Life Instrument (PROSQOLI) is a measure of health-related quality of life (HRQoL) in advanced hormone-resistant prostate cancer. In this study, we aimed at performing a cross-cultural adaptation and validation of the Italian version of the PROSQOLI. PATIENTS AND METHODS: The original version of the PROSQOLI underwent several turnarounds of translations. A total of 472 patients treated with radical prostatectomy, radiotherapy or medical therapy were enrolled for the validation of the questionnaire. The PROSQOLI was administered together with the SF-12. Reliability indexes were calculated by using Cronbach alpha. To evaluate the validity of the construct, relationships between PROSQOLI and SF12 were assessed. The ANOVA test was used to evaluate the differences between groups of patients who had received different treatments. RESULTS: The reliability coefficient was 0.91. Item-to-total correlation indices were in most cases >0.70. The correlation between the scores of the PROSQOLI and those of the SF-12 questionnaire was high (r=0.8139, p<0.0001). The ANOVA test showed significant differences between groups (p<0.01) based on age, recurrence risk and treatment. CONCLUSIONS: The adaptation process showed that the PROSQOLI Italian version has high reliability and presents both convergent and discriminant validity. This version of the tool can be used to assess HRQoL in Italian men who underwent radical treatment for advanced prostate cancer.

Effect of the right ventricular isolation procedure on ventricular vulnerability to fibrillation.

A certain critical mass of myocardium is believed to be necessary to initiate ventricular fibrillation. The right ventricular isolation procedure, employed clinically to confine ventricular tachyarrhythmias to the right ventricle, decreases the ventricular mass available for fibrillation by isolating the ventricles from each other. The effect of this procedure on ventricular fibrillation thresholds is unknown. Left and right ventricular fibrillation thresholds were measured before and after right ventricular isolation in 10 adult mongrel dogs utilizing a single 5 ms stimulus of increasing current strength applied to the epicardium during the vulnerable period. There were no significant differences in heart rate, aortic blood pressure, left atrial pressure, temperature, arterial blood gases or regional myocardial blood flow between the study periods. In 9 of the 10 dogs, the isolated right ventricle could not sustain ventricular fibrillation despite the utilization of stimulus strengths of up to 80 mA. In the 10th dog, the right ventricular fibrillation threshold increased 150%, from 20 to 50 mA. The left ventricular fibrillation threshold markedly increased in every dog, with an average increase from 23 +/- 2 to 40 +/- 4 mA (p less than 0.0005). To determine whether time, cardiopulmonary bypass or the right ventricular incision could cause similar changes in ventricular fibrillation threshold, five different dogs underwent the entire experimental protocol except for incomplete isolation of the right ventricle. There were no significant changes in ventricular fibrillation thresholds in these dogs. Thus, in the canine model, right ventricular isolation can prevent the occurrence of sustained fibrillation in the isolated right ventricle and can significantly increase the left ventricular fibrillation threshold.

Effects of distant potentials on unipolar electrograms in an animal model utilizing the right ventricular isolation procedure.

The effects of distant potentials on local epicardial unipolar electrograms were examined utilizing a model that enabled both ventricles to be paced independently in five dogs. The right ventricular isolation procedure electrically isolates the right from the left ventricle. Right ventricular electrograms were separated into their local (right ventricular) and distant (left ventricular) components by altering the left-right ventricular pacing interval. Waveform configuration, peak to peak amplitude, magnitude of the slope and timing of the fastest downstroke were carefully evaluated at each electrode site, both with and without the presence of distant left ventricular potentials. Except for the timing of the fastest downstroke, all of these variables were significantly altered by distant potentials. Although the slope of the fastest downstroke was significantly affected by distant potentials, it remained a sensitive indicator of local versus distant activation. All electrograms of local right ventricular activation had a slope magnitude greater than 2.5 mV/2 ms whereas none of the right ventricular electrograms containing only distant left ventricular activity had a magnitude greater than 2.5 mV/2 ms. Computer-generated electrograms were calculated by digitally summing the recorded local right and distant left ventricular components. The simulated electrograms correlated well with the recorded electrograms during synchronous ventricular pacing. Thus, the configuration, amplitude and slope of unipolar electrodes were profoundly influenced by distant potentials. The timing of the fastest downstroke is largely independent of the effect of distant potentials and most closely represents local activation. The magnitude of the slope of the recorded electrogram accurately distinguishes local from distant activation.

Lessons learned from data logging in a multicenter clinical trial using a late-generation implantable cardioverter-defibrillator. The Guardian ATP 4210 Multicenter Investigators Group.

OBJECTIVES: This study examined patterns of implantable cardioverter-defibrillator use as documented by data logging. BACKGROUND: Implantable cardioverter-defibrillators are accepted therapy for malignant ventricular tachyarrhythmias; however, relatively little is known about their patterns of use. Incorporation of data-storage capacities into these devices provides insight into long-term defibrillator function. METHODS: Stored data-logging information was retrieved from 401 implanted cardioverter-defibrillators in 393 patients over an average of 303 days of follow-up. RESULTS: A total of 91,443 detections were recorded in 299 patients. One hundred-six patients (26%) had detections due to supraventricular tachycardias, electrical noise or other causes, resulting in inappropriate therapy delivery to 92 patients (23%). Two hundred eighty-one patients recorded 66,276 episodes of ventricular tachycardia or ventricular fibrillation. Of these, 74.4% episodes terminated spontaneously without any delivered therapy, 22.1% terminated after antitachycardia pacing, and 1.7% terminated after shock therapy. Antitachycardia pacing was activated without formal testing in 47% of all patients receiving this therapy and was successful in 96% of all episodes receiving this therapy. Acceleration of tachycardia to shock therapy occurred in 1.3% of all episodes and in 30.5% of patients receiving antitachycardia pacing. Thirty-four patients (8.7%) died during follow-up. Mortality was associated with patient age, heart failure functional class at implantation and frequency of shocks received during follow-up (all p < or = 0.05). CONCLUSIONS: Most ventricular tachyarrhythmia detections by this noncommitted implantable cardioverter-defibrillator resolve spontaneously, whereas the majority receiving therapy can be treated with antitachycardia pacing. Mortality after implantable cardioverter-defibrillator implantation is associated with age, heart failure class and frequency of shocks received during follow-up. Data-logging capabilities provide valuable insights into the patterns of defibrillator use.

Sensing/pacing lead complications with a newer generation implantable cardioverter-defibrillator: worldwide experience from the Guardian ATP 4210 clinical trial.

OBJECTIVES: This report describes the sensing/pacing lead complications that developed during a worldwide clinical trial of a new implantable cardioverter-defibrillator. BACKGROUND: The reliability of the leads used for sensing and pacing with the implantable cardioverter-defibrillator has not been adequately studied. METHODS: The Guardian ATP 4210 was implanted in 302 patients. The sensing/pacing leads consisted of either two unipolar epicardial electrodes or a bipolar endocardial electrode from a variety of manufacturers. RESULTS: During a mean follow-up period of 380 days, 39 patients (12.9%) required reoperation because their device developed sensing/pacing lead system complications. The most common clinical presentation was device oversensing (multiple tachycardia or noise detections or inappropriate shocks), which was observed in 27 patients, whereas elevated pacing thresholds were seen in 10 patients. Forty-one (11.8%) of 347 implanted lead systems required revision. The mean time to revision was 156 +/- 145 days. Actuarial lead survival rate at 1 and 3 years was 89% and 79%, respectively. Epicardial lead systems required significantly (p < 0.05) more revision than did endocardial systems, but when adapter problems were excluded, the revision rates of epicardial and endocardial leads were similar. Causes of lead system failures included adapter connection problems, lead dislodgement and insulation disruption. Predictors of lead revision were use of an epicardial lead system or an adapter. CONCLUSIONS: A high rate of sensing/pacing lead complications was found with this newer generation implantable cardioverter-defibrillator. The enhanced diagnostic and data storage capabilities of this implantable cardioverter-defibrillator facilitated the recognition and troubleshooting of these complications. These findings emphasize the need for careful surveillance and testing of implantable cardioverter-defibrillator sensing/pacing leads during follow-up.

Effects of silodosin on sexual function - realistic picture from the everyday clinical practice.

The treatment with α1-blockers in patients complaining of lower urinary tract symptoms suggestive of benign prostatic hyperplasia (LUTS/BPH) is associated with potential adverse events (AEs), thus including ejaculatory dysfunction (EjD). We sought to assess the effects of a 3-month course of silodosin 8 mg daily dosing on sexual functioning, mainly including ejaculation and orgasm, in a cohort of 100 consecutive sexually active men in the real-life setting. Patients completed the International Index of Erectile Function-Orgasmic Function (IIEF-OF) domain and the International Prostate Symptom Score (IPSS) both at baseline and at survey. Likewise, patients completed a 16-item self-administered questionnaire with closed questions also including specific questions regarding treatment-related adverse events on sexual functioning. Rates and predictors of OF impairment and drug discontinuation were investigated. At survey, silodosin resulted highly effective in improving IPSS-total and subscales (all p < 0.01). Anejaculation, hypospermia, reduced or absent orgasmic feeling, low sexual desire and erectile dysfunction were subjectively reported by 48 (48%), 23 (23%), 11 (11%), 6 (6%), 7 (7%) and 11 (11%) patients respectively. Overall, a reduction in IIEF-OF domain score was observed in 64 (64%) patients. Patients with decreased IIEF-Q9 and/or IIEF-Q10 scores were significantly younger than those without any decrease (p = 0.02). Of all, only 7% of the patients discontinued silodosin because of anejaculation. Silodosin confirms to be highly effective in patients with LUTS/BPH; of them, almost 70% report either anejaculation or hypospermia, with a concomitant OF impairment in 17% of the patients. Younger patients showed higher rates of a concomitant impairment of ejaculation and OF. Overall, anejaculation caused drug discontinuation in 7% of the patients.

Lower urinary tract symptoms among Caucasian-European men who have sex with men: findings from a real-life survey.

BACKGROUND: Prevalence of and severity of lower urinary tract symptoms (LUTS) according to male sexual orientation have been scantly analysed. We aimed to assess the prevalence and severity of LUTS in a cohort of Caucasian-European men who have sex with men seeking medical help for uroandrologic reasons other than LUTS. METHODS: Data from 949 consecutive individuals in an outpatient setting were analysed. Severity of LUTS was measured with the International Prostate Symptom Score (IPSS). Men with storage symptoms scored 1-3 and ⩾ 4 (of 15), and voiding symptoms scored 1-4 and ⩾ 5 (of 20) were considered as having mild and moderate-to-severe symptoms, respectively. For individual symptoms, patients with scores ⩾ 1 were deemed symptomatic (according to Apostolidis et al.(15)). Descriptive statistics and logistic regression models tested the association between LUTS and sexual orientation. RESULTS: Complete data were available for 213 (22.4%) men who have sex with men (MSM) and 736 (77.6%) heterosexuals (mean age (s.d.): 41.0 (12.2) vs 39.9 (12.1) years). Compared with heterosexuals, MSM reported higher rates of total IPSS scores suggestive of moderate (21.6% vs 20%) and severe LUTS (3.8% vs 2.4%) (P=0.004). Similarly, MSM showed higher rates of mild (48.8% vs 45.2%) and moderate-to-severe (39.4% vs 30.4%) storage symptoms (all P<0.001), and of mild (45.1% vs 34.8%) and moderate-to-severe (20.2% vs 19.2%) voiding symptoms (all P<0.01). MSM status was an independent predictor of mild voiding symptoms (odds ratio (OR): 1.40; P=0.004), moderate-to-severe storage symptoms (OR: 1.40; P=0.04) and severe total IPSS (OR: 1.49; P=0.03), after adjusting for other variables. CONCLUSIONS: These findings suggest a higher prevalence and severity of LUTS in MSM compared with heterosexual men seeking medical help for uroandrologic reasons other than LUTS.

Measurement of ventricular electrogram amplitude during intraoperative induction of ventricular tachyarrhythmias.

Adequate sensing of ventricular tachycardia (VT) and ventricular fibrillation (VF) is necessary for proper functioning of an implantable cardioverter defibrillator (ICD). Several ICDs currently undergoing investigation have programmable fixed gain sensitivity for tachycardia detection. If intracardiac electrogram amplitude decreases below the programmed sensitivity during VT or VF, detection of a ventricular arrhythmia may be delayed or missed. The mean amplitude of intracardiac electrograms (ICEGM) recorded with bipolar epicardial or transvenous sensing leads was measured in 63 patients during induced VT and VF recorded in the operating room at the time of ICD implantation. The mean amplitude of the ICEGM during 41 episodes of VF in 15 patients decreased from 14.9 +/- 0.9 mV during sinus rhythm to 8.8 +/- 0.7 mV at 1 second, 9.7 +/- 0.7 mV at 5 seconds, and 9.4 +/- 0.7 mV at 10 seconds (p < 0.0001 vs sinus rhythm ICEGM) with endocardial leads. The mean amplitude of the ICEGM recorded during 173 episodes of VF in 43 patients with epicardial leads decreased from 10.4 +/- 0.3 mV in sinus rhythm to 7.8 +/- 0.3 mV at 1 second, 8.3 +/- 0.3 mV at 5 seconds and 8 mV at 10 seconds (p <0.0001 vs sinus rhythm ICEGM). The mean amplitude of epicardial and transvenous ICEGMs recorded during 34 episodes of monomorphic VT decreased from 18.5 +/- 1.8 mV (epicardial) and 14.4 +/- 2.0 mV (transvenous) during sinus rhythm (p = 0.15, epicardial vs transvenous) to 16.0 +/- 1.7 mV (epicardial) and 13.7 +/- 1.9 mV (transvenous) at 10 seconds (< 10% of baseline amplitude).(ABSTRACT TRUNCATED AT 250 WORDS)
