Abstract
PURPOSE To identify the clinical factors resulting in the failure of dutasteride add-on treatment to alpha-adrenergic antagonist for patients with lower urinary tract symptoms and benign prostatic enlargement (BPE). METHODS We retrospectively surveyed the patient cohort who had been enrolled in the study of dutasteride add-on treatment to alpha-adrenergic antagonist from December 2009 to November 2011. Treatment failure was defined as receiving surgery for BPE or requiring intermittent catheterization or permanent bladder catheter for urinary retention or huge postvoid residual urine. Clinical parameters before dutasteride treatment were compared between the successful and failed group. RESULTS Of 92 patients, 23 (25%) were defined as treatment failure at 7-109 months (mean: 38 months) after dutasteride add-on treatment. In the failed group, the patient' age was younger (71.6 ± 6.8 vs 75.4 ± 8.4, p = 0.033), prostatic volume (PV) was larger (76 ± 41 vs 49 ± 26 ml, p = 0.005), voiding efficiency was lower (54 ± 27 vs 68 ± 24%, p = 0.045) and bladder outlet obstruction index was higher (73 ± 30 vs 48 ± 30, p = 0.015). The cox proportional-hazards model indicated that only intravesical prostatic protrusion (IPP) was associated with treatment failure. Non-failure rate at 3 years after dutasteride add-on treatment was 89% with patients of IPP < 13 mm versus 51% with those of IPP ≥ 13 mm (p < 0.001). CONCLUSION IPP ≥ 13 mm is the risk factor resulting in the failure of dutasteride add-on treatment to alpha-adrenergic antagonist. This kind of information should be provided to the patients early in the clinical practice so that they could consider the necessity of BPE surgery in the long run.

Abstract
BACKGROUND Numerous agents have been suggested for the symptomatic treatment of primary Raynaud's phenomenon. Apart from calcium channel blockers, which are considered to be the drugs of choice, evidence of the effects of alternative pharmacological treatments is limited. This is an update of a review first published in 2008. OBJECTIVES To assess the effects of drugs with vasodilator effects on primary Raynaud's phenomenon as determined by frequency, severity, and duration of vasospastic attacks; quality of life; adverse events; and Raynauds Condition Score. SEARCH METHODS The Cochrane Vascular Information Specialist searched the Cochrane Vascular Specialised Register, CENTRAL, MEDLINE, Embase, and CINAHL databases, and the World Health Organization International Clinical Trials Registry Platform and the ClinicalTrials.gov trial register to November 16, 2020. SELECTION CRITERIA We included randomized controlled trials evaluating effects of oral, intravenous, and topical formulations of any drug with vasodilator effects on subjective symptoms, severity scores, and radiological outcomes in primary Raynaud's phenomenon. Treatment with calcium channel blockers was not assessed in this review, nor were these agents compared. DATA COLLECTION AND ANALYSIS Two review authors independently selected studies for inclusion, assessed studies using the Cochrane "Risk of bias" tool, and extracted study data. Outcomes of interest included frequency, severity, and duration of attacks; quality of life (QoL); adverse events (AEs); and the Raynaud Condition Score (RCS). We assessed the certainty of the evidence using GRADE. MAIN RESULTS We identified seven new studies for this update. In total, we included 15 studies involving 635 participants. These studies compared different vasodilators to placebo. Individual studies used different methods and measures to report different outcomes. Angiotensin-converting enzyme (ACE) inhibitors Combining data from three studies revealed a possible small increase in the frequency of attacks per week after treatment (captopril or enalapril) compared to placebo (mean difference [MD] 0.79, 95% confidence interval [CI] 0.43 to 1.17; low-certainty evidence). There was no evidence of a difference between groups in severity of attacks (MD -0.17, 95% CI -4.66 to 4.31; 34 participants, 2 studies; low-certainty evidence); duration of attacks (MD 0.54, 95% CI -2.42 to 1.34; 14 participants, 1 study; low-certainty evidence); or AEs (risk ratio [RR] 1.35, 95% CI 0.67 to 2.73; 46 participants, 3 studies; low-certainty evidence). QoL and RCS were not reported. Alpha blockers Two studies used alpha blockers (buflomedil or moxisylyte). We were unable to combine data due to the way results were presented. Buflomedil probably reduced the frequency of attacks compared to placebo (MD -8.82, 95% CI -11.04 to -6.60; 31 participants, 1 study; moderate-certainty evidence) and may improve severity scores (MD -0.41, 95% CI -0.62 to -0.30; moderate-certainty evidence). With moxisylyte, investigators reported fewer attacks (P < 0.02), less severe symptoms (P < 0.01), and shorter duration of attacks, but the clinical relevance of these results is unclear. No evidence of a difference in AEs between buflomedil and placebo groups was noted (RR 1.41, 95% CI 0.27 to 7.28; 31 participants, 1 study; moderate-certainty evidence). More AEs were observed in participants in the moxisylyte group than in the placebo group. Prostaglandin/prostacyclin analogues One study compared beraprost versus placebo. There was no evidence of benefit for frequency (MD 2.00, 95% CI -0.35 to 4.35; 118 participants, low-certainty evidence) or severity (MD -0.06, 95% CI -0.34 to 0.22; 118 participants, low-certainty evidence) of attacks. Overall, more AEs were noted in the beraprost group (RR 1.59, 95% CI 1.05 to 2.42; 125 participants; low-certainty evidence). This study did not report on duration of attacks, QoL, or RCS. Thromboxane synthase inhibitors One study compared a thromboxane synthase inhibitor (dazoxiben) versus placebo. There was no evidence of benefit for frequency of attacks (MD 0.8, 95% CI -1.81 to 3.41; 6 participants; very low-certainty evidence). Adverse events were not reported in subgroup analyses of participants with primary Raynaud's phenomenon, and the study did not report on duration of attacks, severity of symptoms, QoL, or RCS. Selective serotonin reuptake inhibitors One study compared ketanserin with placebo. There may be a slight reduction in the number of attacks per week with ketanserin compared to placebo (MD -14.0, 95% CI -27.72 to -0.28; 41 participants; very low-certainty evidence) and reduced severity score (MD -133.00, 95% CI -162.40 to -103.60; 41 participants; very low-certainty evidence). There was no evidence that ketanserin reduced the duration of attacks (MD -4.00, 95% CI -14.82 to 6.82; 41 participants; very low-certainty evidence), or that AEs were increased in either group (RR 1.54, 95% CI 0.89 to 2.65; 41 participants; very low-certainty evidence). This study did not report on QoL or RCS. Nitrate/nitrate derivatives Four studies compared topical treatments of nitroglycerin or glyceryl trinitrate versus placebo, each reporting on limited outcomes. Meta-analysis demonstrated no evidence of effect on frequency of attacks per week (MD -1.57, 95% CI -4.31 to 1.17; 86 participants, 2 studies; very low-certainty evidence). We were unable to pool any data for the remaining outcomes. Phosphodiesterase inhibitors Three studies compared phosphodiesterase inhibitors (vardenafil, cilostazol or PF-00489791) to an equivalent placebo. Results showed no evidence of a difference in frequency of attacks (standardized MD [SMD] -0.05, 95% CI -6.71 to 6.61; 111 participants, 2 studies; low-certainty evidence), severity of attacks (MD -0.03, 95% CI -1.04 to 0.97; 111 participants, 2 studies; very low-certainty evidence), duration of attacks (MD -1.60, 95% CI -7.51 to 4.31; 73 participants, 1 study; low-certainty evidence), or RCS (SMD -0.8, 95% CI -1.74 to 0.13; 79 participants, 2 studies; low-certainty evidence). Study authors reported that 35% of participants on cilostazol complained of headaches, which were not reported in the placebo group. PF-00489791 caused 34 of 54 participants to experience AEs versus 43 of 102 participants receiving placebo (RR 1.49). Headache was most common, affecting 14 participants (PF-00489791) versus nine participants (placebo). AUTHORS' CONCLUSIONS The included studies investigated several different vasodilators (topical and oral) for treatment of primary Raynaud's phenomenon. Small sample sizes, limited data, and variability in outcome reporting yielded evidence of very low to moderate certainty. Evidence is insufficient to support the use of vasodilators and suggests that vasodilator use may even worsen disease.

Abstract
OBJECTIVE Alpha-adrenergic blockade is currently the first choice of preoperative treatment in patients with functional pheochromocytoma and sympathetic paraganglioma. Nevertheless, there is no consensus whether selective or non-selective alpha-blockade is superior for preventing both perioperative hemodynamic instability and complications. DESIGN Our study aimed to compare selective and non-selective alpha-blockade through a systematic review with meta-analysis. METHODS MEDLINE, Embase, Web of Science and Cochrane Library were searched for eligible studies. Randomized and observational studies comparing selective and non-selective alpha-blockade in pheochromocytoma and sympathetic paraganglioma surgery in adults were included. Data on perioperative hemodynamic parameters and postoperative outcomes were extracted. RESULTS Eleven studies with 1344 patients were enrolled. Patients receiving selective alpha-blockade had higher maximum intraoperative systolic blood pressure (WMD: 12.14 mmHg, 95% CI: 6.06-18.21, P < 0.0001) compared to those treated with non-selective alpha-blockade. Additionally, in the group pretreated with selective alpha-blockers, intraoperative vasodilators were used more frequently (OR: 2.46, 95% CI 1.44-4.20, P = 0.001). Patients treated with selective alpha-blockers had lower minimum intraoperative systolic blood pressure (WMD: -2.03 mmHg, 95% CI: -4.06 to -0.01, P = 0.05) and shorter length of hospital stay (WMD: -0.58 days, 95% CI: -1.12 to -0.04, P = 0.04). Operative time, overall morbidity and mortality did not differ between the groups. CONCLUSIONS This meta-analysis shows non-selective alpha-blockade was more effective in preventing intraoperative blood pressure fluctuations while maintaining comparable risk of both intraoperative and postoperative hypotension and overall morbidity.

Abstract
CONTEXT Pretreatment with α-adrenergic receptor blockers is recommended to prevent hemodynamic instability during resection of a pheochromocytoma or sympathetic paraganglioma (PPGL). OBJECTIVE To determine which type of α-adrenergic receptor blocker provides the best efficacy. DESIGN Randomized controlled open-label trial (PRESCRIPT; ClinicalTrials.gov NCT01379898). SETTING Multicenter study including 9 centers in The Netherlands. PATIENTS 134 patients with nonmetastatic PPGL. INTERVENTION Phenoxybenzamine or doxazosin starting 2 to 3 weeks before surgery using a blood pressure targeted titration schedule. Intraoperative hemodynamic management was standardized. MAIN OUTCOME MEASURES Primary efficacy endpoint was the cumulative intraoperative time outside the blood pressure target range (ie, SBP >160 mmHg or MAP <60 mmHg) expressed as a percentage of total surgical procedure time. Secondary efficacy endpoint was the value on a hemodynamic instability score. RESULTS Median cumulative time outside blood pressure targets was 11.1% (interquartile range [IQR]: 4.3-20.6] in the phenoxybenzamine group compared to 12.2% (5.3-20.2)] in the doxazosin group (P = .75, r = 0.03). The hemodynamic instability score was 38.0 (28.8-58.0) and 50.0 (35.3-63.8) in the phenoxybenzamine and doxazosin group, respectively (P = .02, r = 0.20). The 30-day cardiovascular complication rate was 8.8% and 6.9% in the phenoxybenzamine and doxazosin group, respectively (P = .68). There was no mortality after 30 days. CONCLUSIONS The duration of blood pressure outside the target range during resection of a PPGL was not different after preoperative treatment with either phenoxybenzamine or doxazosin. Phenoxybenzamine was more effective in preventing intraoperative hemodynamic instability, but it could not be established whether this was associated with a better clinical outcome.

Abstract
OBJECTIVES To determine the minimal important difference (MID) of the International Prostate Symptom Score (IPSS) and the Overactive Bladder Questionnaire short form (OAB-q SF) assessed in primary care among patients treated for lower urinary tract symptoms (LUTS). DESIGN Single-arm, open-label observational cohort study with a 6-week follow-up. SETTING Twenty-two pharmacies in the Netherlands. PARTICIPANTS We enrolled Dutch men with uncomplicated LUTS who received a new alpha-blocker prescription from their general practitioner or urologist. PRIMARY AND SECONDARY OUTCOMES The IPSS and OAB-q SF were completed before and after 6 weeks of therapy. At 6 weeks, men also completed the Patient Global Impression of Improvement (PGI-I). The mean change scores of the IPSS and OAB-q SF were calculated for each PGI-I outcome category, with the category 'a little better' used to determine the MID. The SE of measurement (SEM) was calculated for each questionnaire. RESULTS In total, 165 men completed follow-up. The MID was 5.2 points (95% CI 3.9 to 6.4; SEM 3.6) for the IPSS and 11.0 points (95% CI 7.1 to 14.9; SEM 9.7) for the OAB-q SF. For both questionnaires, CIs showed an overlap with the no-change categories. However, the MID for the IPSS was higher in men with severe baseline symptoms (7.1; 95% CI 5.3 to 9.0) than in men with moderate baseline symptoms (3.2; 95% CI 1.7 to 4.8). CONCLUSION In this study, the MID for the IPSS was considerably higher than the MID of 3.1 reported in the only other study on this topic, but may be due to methodological differences. Interpretation of the MID for the OAB-q SF is hampered by the overlap with the SEM. Future studies are needed to confirm our results because correlations between the PGI-I and symptom questionnaires were suboptimal.

Abstract
BACKGROUND We aim to examine the trend in the use of antimuscarinics and off-label alpha-adrenergic blockers for treatment of lower urinary tract symptoms (LUTS) in a Taiwanese Women Cohort between 2007 and 2012. METHODS This population-based National Health Insurance Research Database (NHIRD) was used to examine the trends in the use of antimuscarinics or off-label alpha-adrenergic blockers in Taiwan. A sample of 1,000,000 individuals randomly drawn from the whole population of 23 million individuals who were registered in the NHI in 2005. From 2007 through 2012, women aged over 18 years whose claim record contained prescriptions of either of the two drugs for treatment of any of the LUTS-related diagnoses were identified and analyzed. The annual usage of the two drug classes were calculated by defined daily dose (DDD). RESULTS From 2007-2012, there was a 0.80 fold (69676.8 to 125104.3) increase in DDD of antimuscarinics in our cohort. The overall healthcare seeking prevalence of LUTS was 7.33% in 2007 and 12.38% in 2012, in a rising trend. The prevalence of antimuscarinics-treated LUTS in our cohort increased from 2.53 in 2007 to 3.41 per 1000 women in 2012. The prevalence of LUTS treated by antimuscarinics increased especially for those older than 60 years during the study period. CONCLUSIONS This 6-year observational study provided the epidemiologic information of clinically significant LUTS of Asian female population. Moreover, there was a rising trend in the use of antimuscarinics and off-label alpha-adrenergic blockers in the population-based cohort.

Abstract
Dorsal raphe nucleus (DRN) neurons are reciprocally connected to the locus coeruleus (LC) and send neural pathways to the medial hypothalamus (MH). The aim of this work was to investigate whether the blockade of α1-, α2- or β-noradrenergic receptors in the DRN or the inactivation of noradrenergic neurons in the LC modify defensive behaviours organised by MH neurons. For this purpose, Wistar male rats received microinjections of WB4101, RX821002, propranolol (α1-, α2- and β-noradrenergic receptor antagonists, respectively) or physiological saline in the DRN, followed 10 min later by MH GABAA receptor blockade. Other groups of animals received DSP-4 (a noradrenergic neurotoxin), physiological saline or only a needle insertion (sham group) into the LC, and 5 days later, bicuculline or physiological saline was administered in the MH. In all these cases, after MH treatment, the frequency and duration of defensive responses were recorded over 15 min. An anterograde neural tract tracer was also deposited in the DRN. DRN neurons send pathways to lateral and dorsomedial hypothalamus. Blockade of α1- and β-noradrenergic receptors in the DRN decreased escape reactions elicited by bicuculline microinjections in the MH. In addition, a significant increase in anxiety-like behaviours was observed after the blockade of α2-noradrenergic receptors in the DRN. LC pretreatment with DSP-4 decreased both anxiety- and panic attack-like behaviours evoked by GABAA receptor blockade in the MH. In summary, the present findings suggest that the norepinephrine-mediated system modulates defensive reactions organised by MH neurons at least in part via noradrenergic receptors recruitment on DRN neurons.

Abstract
Purpose α-Blockers are commonly used for the treatment of male lower urinary tract symptoms (LUTS). The Dutch GP guideline on male LUTS contains an advice to discontinue treatment after 3–6 months of successful treatment. The guideline for urologists does not support this advice. It is unclear if these differences lead to other patterns of (dis)continuation of α-blockers. We aim to study continuation rates of α-blockers, prescribed by a urologist or a general practitioner (GP), and to predict discontinuation after 1 year. Methods We conducted a retrospective inception cohort study on prescription patterns of α-blockers among Dutch men between 2006 and 2014, using the IADB.nl pharmacy prescription database from the University of Groningen. We selected men aged 30 years or older with a first α-blocker prescription between 2006 and 2013, and analysed continuation of prescriptions. Results The database included 12,191 individual patients with at least one α-blocker prescriptions from a urologist (44.5%) or a GP (55.5%). The median treatment period for patients who started in the GPs office was 210 days, compared to 150 days for patients with a prescription from a urologist. Of all patients, 60.3% (GP prescriptions) and 66.1% (urologists’ prescriptions) had discontinued treatment (Chi-square p < 0.001). Discontinuation rates were age dependent with higher rates in the youngest age groups. Conclusion In this study, the discontinuation rate 1 year after the initiation of treatment was high. Although Dutch GP’s and urologist’s guidelines differ with respect to a discontinuation advice, we could not find clinically relevant difference in (temporary) discontinuation rates.

Abstract
BACKGROUND Many patients with Parkinson's disease (PD) suffer from sialorrhea. Sialorrhea is often treated with anticholinergics and botulinum toxin, but some adverse effects have limited the use of these treatments. Dihydroergotoxine mesylate is an α-adrenergic blocking agents as well as some affinities to the dopaminergic and serotonin (5-HT) receptors. In the current study, we examine the safety and efficacy of dihydroergotoxine mesylate in PD patients. METHODS This study consisted of 2 phases. The intervention was 2.5-mg oral dihydroergotoxine mesylate twice daily in both phases. The first phase is a three-week open-label single-arm trial (n = 10). The second phase was a six-week randomized controlled trials with a crossover design (n = 20). Efficacy was assessed using the United Parkinson's Disease Rating Scale (UPDRS) sialorrhrea subscore and Sialorrhea Clinical Scale for PD (SCS-PD). RESULTS In the first phase, the UPDRS sialorrhea score was 3.5 ± 0.53 vs. 1.9 ± 0.57 prior to and after the treatment (P = 0.004). The SCS-PD score decreased from 15.8 ± 2.78 to 9.9 ± 3.00 after the treatment (P = 0.005). The response rate (defined by at least 30% reduction in SCS-PD score) was 60%. In the second phase of crossover trial, the UPDRS sialorrhea score was 3.00 ± 0.56 in placebo weeks vs. 2.00 ± 0.65 on dihydroergotoxine in dihydroergotoxine weeks (P = 0.001). The SCS-PD was 12.50 ± 2.84 and 9.25 ± 2.86 versus, respectively (P < 0.001). The response rate was 10% and 55%, respectively (P = 0.003). There were no significant adverse effects. CONCLUSIONS Dihydroergotoxine mesylate is safe and effective for sialorrhea in PD patients.

Abstract
Treating male lower urinary tract symptoms (LUTS) by targeting the prostate would have limited effect on overactive bladder (OAB) symptoms. This study assessed perceived symptoms and quality of life (QoL) of male patients with OAB treated with an α-blocker plus solifenacin in daily clinical practice. Male patients aged ≥40 years were included after the decision was made to initiate treatment with an α-blocker for LUTS plus solifenacin for OAB symptoms. The primary endpoint was change in patient perception of bladder condition (PPBC) questionnaire score over 6 months. Other assessments included the OAB-questionnaire short form (OAB-q SF) and International Prostate Symptom Score (IPSS). Interpretation of the study data was hindered by not meeting the enrollment target and a high dropout rate. In 36 evaluable patients, mean (SD) PPBC score improved from 4.3 (0.93) at baseline ("moderate" to "severe" problems) to 3.5 (1.06) at month 6 ("minor" to "moderate" problems). OAB-q SF scores and total IPSS also improved. In this patient population, treatment with solifenacin and an α-blocker resulted in improvements in male patient perception of their LUTS and QoL, although the results should be interpreted with caution due to the low number of patients with complete data.

Abstract
The giant cystic pheochromocytoma is a rare adrenal tumor in the predominantly asymptomatic course; so many cases are not diagnosed until the time of surgery. The simple mobilization of the tumor is associated with the passage to the blood of large amounts of catecholamines and high morbidity and mortality. So the surgery itself and perioperative management are a huge challenge. This article describes the case of a malignant giant pheochromocytoma (35 cm) which occupied the entire right abdomen. Even with the preoperative diagnosis of pheochromocytoma, pharmacological blockade preoperative and intraoperative measures, the patient died shortly before the end of surgery.

Abstract
BACKGROUND The uptake of percutaneous coronary procedures via the radial artery has increased internationally due to the decreased risk of complications and increased patient satisfaction. The increased susceptibility of the radial artery to spasm however presents a potential risk for procedural failure. Although most experts agree on the need for prophylactic medications to reduce radial artery spasm, currently there is inconsistency in literature regarding the most effective vasodilatory medication or combination of medications. REVIEW OBJECTIVE The objective of this study is to identify the effectiveness of vasodilatory medications on radial artery spasm in patients undergoing transradial coronary artery procedures. INCLUSION CRITERIA TYPES OF PARTICIPANTS This review considered studies that included participants aged 18 years and over undergoing non-emergent transradial percutaneous coronary artery procedures. TYPES OF INTERVENTION(S) This review considered studies that used vasodilating intravenous and intra-arterial medications or combinations of medications prior to commencing and during transradial coronary approaches to reduce radial artery spasm. OUTCOMES The outcomes of interest were the incidence of radial artery spasm during percutaneous coronary procedure using objective and/or subjective measures and its effect on the successful completion of the procedure. TYPES OF STUDIES Randomized controlled trials published in the English language between 1989 to date were considered for inclusion. SEARCH STRATEGY The search strategy aimed to find both published and unpublished studies. A three-step search strategy was utilized in this review. An initial search of MEDLINE, CINAHL and Scopus was undertaken, followed by a search for unpublished studies. ASSESSMENT OF METHODOLOGICAL QUALITY Papers selected for retrieval were assessed by two independent reviewers for methodological validity prior to inclusion in the review using standardized critical appraisal instruments. Any disagreements that arose between the reviewers were resolved through discussion. DATA EXTRACTION Quantitative data was extracted from papers included in the review using the standardized data extraction tool from RevMan5 (Copenhagen: The Nordic Cochrane Centre, Cochrane). DATA SYNTHESIS Quantitative data, where possible, was pooled in statistical meta-analysis using RevMan5. All results were subject to double data entry. Effect sizes expressed as risk ratio (for categorical data) and weighted mean differences (for continuous data) and their 95% confidence intervals were calculated for analysis. RESULTS Nine trials involving 3614 patients were included in the final review. Pooled data involving 992 patients on the effect of calcium channel blockers demonstrated a statistically significant reduction in the incidence of vasospasm in patients who received verapamil 5 mg compared to those who received a placebo (OR 0.33; 95%CI 0.19, 0.58). Similarly patients who received verapamil 2.5 mg or 1.25 mg had significantly fewer incidences of vasospasm when compared to those who received a placebo. Nitroglycerine 100mcg was demonstrated to be associated with a statistically significant reduction in the incidence of vasospasm. CONCLUSION The evidence demonstrates a benefit in the use of vasodilatory medications for the reduction of vasospasm in patients having radial coronary procedures. Further large-scale multi-center trials are needed to determine the preferred medication.

Abstract
The link between neurotransmitter-level effects of antidepressants and their clinical effect remain poorly understood. A single dose of mirtazapine decreases limbic responses to fearful faces in healthy subjects, but it is unknown whether this effect applies to complex emotional situations and dynamic connectivity between brain regions. Thirty healthy volunteers listened to spoken emotional narratives during functional magnetic resonance imaging (fMRI). In an open-label design, 15 subjects received 15mg of mirtazapine two hours prior to fMRI while 15 subjects served as a control group. We assessed the effects of mirtazapine on regional neural responses and dynamic functional connectivity associated with valence and arousal. Mirtazapine attenuated responses to unpleasant events in the right fronto-insular cortex, while modulating responses to arousing events in the core limbic regions and the cortical midline structures (CMS). Mirtazapine decreased responses to unpleasant and arousing events in sensorimotor areas and the anterior CMS implicated in self-referential processing and formation of subjective feelings. Mirtazapine increased functional connectivity associated with positive valence in the CMS and limbic regions. Mirtazapine triggers large-scale changes in regional responses and functional connectivity during naturalistic, emotional stimuli. These span limbic, sensorimotor, and midline brain structures, and may be relevant to the clinical effectiveness of mirtazapine.

Abstract
BACKGROUND As a monotherpay, a-blockers and anti-muscarinics are both efficacy for ureteral stent-related symptoms (SRS). The aim of the study was to systematically evaluate their efficacy of a combination therapy for SRS. METHODS Relevant studies investigating α-blockers and/or anti-muscarinics for SRS were identified though searching online databases including PubMed, EMBASE, Cochrane Library, and other sources up to March 2016. The RevMan software was used for data analysis, and senesitivity analysis and inverted funnel plot were also adopted. RESULTS Seven randomized controlled trials (RCTs) and 1 prospective controlled trial including 545 patients were selected. Compared with α-blockers, the combination group achieved significant improvements in total International Prostate Symptom Score (IPSS) [-3.93 (2.89, 4.96), P < 0.00001], obstructive subscore [-1.29 (0.68, 1.89), P < 0.0001], irritative subscore [-2.93 (2.18, 3.68), P < 0.00001], and quality of life score [-0.99 (0.42, 1.55), P < 0.001]. Compared with antimuscarinics, there were also significant differences in total IPSS [-3.49 (2.43, 4.55), P < 0.00001], obstructive subscore [-1.40 (0.78, 2.01), P < 0.00001], irritative subscore [-2.10 (1.30, 2.90), P < 0.00001], and quality of life score [-1.18 (0.58, 1.80), P < 0.001] in favor of combination group. No significant difference was found in the visual analog pain score and the urinary symptoms score in Ureteral Stent Symptom Questionnaire (USSQ). No significant difference in complications was found. CONCLUSIONS Current analysis shows significant advantages of combination therapy compared with monotherapy of α-blockers or antimuscarinics alone mainly based on IPSS. More RCTs adopting validated USSQ as outcome measures are warranted to support the finding.

Abstract
BACKGROUND There is still controversy as to whether initial combination treatment is superior to serial addition of anticholinergics after maintenance or induction of alpha blockers in benign prostatic hyperplasia (BPH)/lower urinary tract symptoms (LUTS). OBJECTIVE The objective of this study was to determine the benefits and safety of initial combination treatment of an alpha blocker with anticholinergic medication in BPH/LUTS through a systematic review and meta-analysis. METHODS We conducted a meta-analysis of improvement in LUTS using International Prostate Symptom Score (IPSS), maximal urinary flow rate (Qmax), post-voided residual volume (PVR), and quality of life (QoL). RESULTS In total, 16 studies were included in our analysis, with a total sample size of 3,548 subjects (2,195 experimental subjects and 1,353 controls). The mean change in total IPSS improvement from baseline in the combination group versus the alpha blocker monotherapy group was -0.03 (95% CI: -0.14-0.08). The pooled overall SMD change of storage IPSS improvement from baseline was -0.28 (95% CI: -0.40 - -0.17). The pooled overall SMD changes of QoL, Qmax, and PVR were -0.29 (95% CI: -0.50 - -0.07), 0.00 (95% CI: -0.08-0.08), and 0.56 (95% CI: 0.23-0.89), respectively. There was no significant difference in the number of acute urinary retention (AUR) events or PVR. CONCLUSIONS Initial combination treatment of an alpha blocker with anticholinergic medication is efficacious for in BPH/ LUTS with improved measures such as storage symptoms and QoL without causing significant deterioration of voiding function.

Abstract
Lower urinary tract symptoms (LUTS) secondary to benign prostatic obstruction (BPO) represent one of the most common clinical complaints in adult men. Several drugs used for LUTS/BPO may strongly affect sexual function and bother. The aim of this systematic review and meta-analysis was to evaluate the impact of combination therapy with alpha-blockers (AB), 5-alpha reductase inhibitors (5-ARI) on the risk of erectile dysfunction(ED) and libido alterations (LA) from randomized clinical trial (RCT). Based on the inclusion and exclusion criteria, five RCTs involving 6131 patients were included in the analysis. According to the analysis, the overall prevalence of ED and LA were significantly greater in the combination treatment group than in the AB group (7.93% versus 4.66%; OR 1.81; p < 0.0001 and 3.69% versus 2.36%; OR 1.58; p = 0.003, respectively). The combination therapy increased the risk of ED compared to monotherapy with 5-ARI (7.93% versus 6.47%; OR 1.25; p = 0.04) but not the risk of LA (3.51% versus 3.37; OR 1.03; p = 0.84). In our systematic meta-analysis, we demonstrated that combination therapy with ABs and 5-ARIs was associated with significantly higher risk of ED and LA compared with single monotherapy. Combination therapy showed similar risk of LA compared with 5-ARI monotherapy.

Abstract
The aim of this study is to determine the effect of combining extracorporeal shock-wave therapy (ESWT) and triple therapy versus triple therapy alone, when treating Category III B chronic prostatitis (CPPS). Study included 60 patients, classified as having CPPS, divided into two groups: the first group numbered 30 patients, who were treated with a combination of an α-blocker, an anti-inflammatory agent and a muscle relaxant; the second group consisted of 30 patients who received a combination of ESWT and the fore-mentioned triple therapy. Patients were treated for 12 weeks. The primary criterion of a response to therapy was scoring 2 or less on the NIH-CPSI quality of life item, while the secondary criterion of a response to therapy was a greater than a 50% reduction in NIH-CPSI pain score. Patients who received triple therapy did not show a significant change neither in post void residual urine (PVR) nor in maximum flow rate (QMAX), while the second group of patients exhibited significant improvement in both PVR and QMAX values. Both groups of patients showed statistically significant improvement in all items of the NIH-CPSI score after the treatment, with significantly better results in the second group.

Abstract
OBJECTIVE Elevated uterine artery resistance has been associated with the development of preeclampsia. We sought to determine if the human uterine arterial circulation was more sensitive to alpha-adrenergic blockade than a control vascular bed. METHODS We studied 38 healthy nulliparous women during the follicular phase of the menstrual cycle. Arteriolized venous blood was measured for plasma epinephrine and norepinephrine. Doppler ultrasound of the uterine and upper extremity radial artery was performed before and after intravenous administration of phentolamine. Heart rate and volumetric flow were calculated. Data are presented as means +/- SD. RESULTS Mean heart rate before and after administration of phentolamine was 63 +/- 11 and 68 +/- 12 beats per minute (7.5% increase, P <.001). Mean radial artery blood flow before and after administration of phentolamine was 4.6 +/- 4.7 mL/min and 5.8 +/- 5.9 mL/min (19.9% increase, P =.071). Mean uterine blood flow before and administration of phentolamine was 15.4 +/- 10.1 mL/min and 27.3 +/- 17.5 mL/min (43.7% increase, P <.001). The uterine response (43.7% increase) and radial response (19.9% increase) were significantly different (P <.001). The increase in uterine blood flow after phentolamine administration was linked with resting norepinephrine (r = 0.394, P =.063). CONCLUSION We found evidence that uterine alpha-adrenergic tone is more sensitive to blockade by phentolamine than upper extremity radial circulation. This provides evidence for a differential responsiveness and sensitivity to alpha-adrenergic blockade in different vascular beds. We theorize that the increased adrenergic tone associated with preeclampsia may contribute disproportionately to decreased uterine blood flow.

Abstract
Phentolamine is a reversible competitive α-adrenergic antagonist with similar affinities for α1 and α2 receptors. It has a long history of safe clinical use, and was developed as a potential therapy for male erectile dysfunction because of its capacity to increase the arteriolar blood flow to the corpora cavernosa. Phentolamine mesylate was administered to rats by oral gavage at daily doses of 10, 50, and 150 mg/kg for 24 months. A dose-related increase in mortality, ascribed to an exaggerated pharmacologic effect, was seen at high doses. Systemic exposure as measured by plasma drug concentration increased with dose and duration of dosing and slight drug accumulation occurred, particularly in high-dose males. In the treated groups, 10 males and 1 female were diagnosed with hibernomas, neoplasms of brown adipose tissue, which appeared in the thoracic cavity or retroperitoneal area as circumscribed, tan to reddish-brown lobulated masses. Histologically, the masses were well circumscribed with variably sized lobules defined by a rich capillary network and consisted of closely apposed oval to polygonal cells with large amounts of cytoplasm and a centrally located nucleus. The cytoplasm's appearance varied from multivacuolated to univacuolated to granular eosinophilic. In a few cases, neoplastic emboli were observed in capsular vessels. Ultrastructurally, the neoplastic cells contained numerous mitochondria with transverse parallel cristae that occupied over 60% of the cytoplasm and lipid droplets. This study documents the previously unreported development of hibernomas in rats treated with phentolamine mesylate.

Abstract
AIM The aim of the paper is to study the clinical efficacy of carvedilol and ornithine-aspartate in the complex therapy (ACE inhibitors, diuretics, cardiac glycosides, nitrates indication), to assess their impact on quality of life, intracardiac hemodynamics, remodeling of the left (LV) and right ventricular (RV), indicators of the inflammatory enzyme activity in blood serum of patients with coronary heart disease with CHF II-III FC and alcoholic liver disease (ALD). MATERIALS AND METHODS 95 patients were studied 45-75 years (mean age - 58,2 ± 1,2) with CHF II-III FC and postinfarction cardiosclerosis, LVEF less than 45%. ALD was diagnosed in 58 patients. In 23 (39%) patients among them had steatosis, 18 (30.5%) - chronic hepatitis (CH), 17 (30.5%) - liver cirrhosis (LC). Patients were divided into 3 groups. Patients in the first group (37 people) with coronary artery disease and heart failure without a UPS received an average dose of carvedilol in - 32,8 ± 4,7 mg / day. Patients in the 2nd group (32 persons) suffering from coronary artery disease, heart failure, and UPS received carvedilol in an average dose of 25,4 ± 1,6- mg / day and L-ornithine-L-aspartate in a dose of 10 g granulate per day for 2 weeks, and then by 5g a day for 4 months. Patients in the third control group (26 people) with CHD and CHF and CHF ABP received basic therapy (without β-blocker) and ademetionine at a dose of 800 mg / day for 2 weeks, followed by 400 mg / day for 4 months. RESULTS After 4 months of observation, it was noted that CHF patients with IHD in combination with BPO flows less favorably. In all groups, the clinical status of patients was improved on the background of the therapy, however, the clinical status was more pronounced while using carvedilol and ornithine-aspartate (Group 2): summary measure of quality of life has improved by 38 points, the speed of the test increased with a digital sequence up to 54.4, decreased shortness of breath, edema, ascites, portal hypertension effects, hepatocellular insufficiency and hepatic encephalopathy. In general, was shown the normalization of sleep rhythm, reducing sleepiness, improved memory, attention, reduced asterixis and sweeping hand tremor, asthenia. CONCLUSIONS The use of carvedilol and ornithine-aspartate in the treatment of patients with CHF FC II-III with CHD and BPO improves the clinical condition of patients, quality of life, hemodynamics, reduces the severity of pulmonary hypertension and normalizes serum biochemical parameters.

Abstract
Aim: we aimed to systematically review drugs to treat lower urinary tract symptoms (LUTS) regularly used in older persons to classify appropriate and inappropriate drugs based on efficacy, safety and tolerability by using the Fit fOR The Aged (FORTA) classification. Methods: to evaluate the efficacy, safety and tolerability of drugs used for treatment of LUTS in older persons, a systematic review was performed. Papers on clinical trials and summaries of individual product characteristics were analysed regarding efficacy and safety in older persons (≥65 years). The most frequently used drugs were selected based on current prescription data. An interdisciplinary international expert panel assessed the drugs in a Delphi process. Results: for the 16 drugs included here, a total of 896 citations were identified; of those, only 25 reported clinical trials with explicit data on, or solely performed in older people, underlining the lack of evidence in older people for drug treatment of LUTS. No drug was rated at the FORTA-A-level (indispensable). Only three were assigned to FORTA B (beneficial): dutasteride, fesoterodine and finasteride. The majority was rated FORTA C (questionable): darifenacin, mirabegron, extended release oxybutynin, silodosin, solifenacin, tadalafil, tamsulosin, tolterodine and trospium. FORTA D (avoid) was assigned to alfuzosin, doxazosin, immediate release oxybutynin, propiverine and terazosin. Conclusions: dutasteride, fesoterodine and finasteride were classified as beneficial in older persons or frail elderly people (FORTA B). For most drugs, in particular those from the group of α-blockers and antimuscarinics, use in this group seems questionable (FORTA C) or should be avoided (FORTA D).

Abstract
A wide array of drugs are available for the treatment of lower urinary tract symptoms associated with benign prostatic hyperplasia (BPH), but the evidence for the comparative effectiveness is controversial.The objective of this study is to evaluate the comparative effectiveness and safety of monodrug therapies for BPH.Data sources are MEDLINE, EMBASE, and the Cochrane Library.We included randomized controlled trials that compared α-blockers, 5-alpha reductase inhibitors (5ARIs), muscarinic receptor antagonists (MRAs), phosphodiesterase-5 inhibitor (PDE5-Is), or placebo for the treatment of BPH.Comparative effectiveness and safety were pooled by both traditional meta-analysis and network meta-analysis. Summary effect size was calculated as mean difference (MD) and relative risk (RR), together with the 95% confidence intervals (CIs).This study included 58,548 participants from 124 trials in total. When compared with placebo, α-blockers, 5ARIs, and PDE5-Is reduced International Prostate Symptom Score (IPSS) by -1.35 to -3.67 points and increased peak urinary flow rate (PUF) by -0.02 to 1.95 mL/s, with doxazosin (IPSS: MD, -3.67[-4.33 to -3.02]; PUF: MD, 1.95[1.61 to 2.30]) and terazosin (IPSS: MD, -3.37 [-4.24 to -2.50]; PUF: MD, 1.21[0.74 to 1.66]) showing the greatest improvement. The improvement in the IPSS was comparable among tamsulosin, alfuzosin, naftopidil, silodosin, dutasteride, sildenafil, vardenafil, and tadalafil. The incidence of total adverse events and withdraws due to adverse events were generally comparable among various agents.In conclusion, α-blockers, 5ARIs, and PDE5-Is are effective for BPH, with doxazosin and terazosin appearing to be the most effective agents. Drug therapies for BPH are generally safe and well-tolerated, with no major difference regarding the overall safety profile.

Abstract
Purpose α1 receptors and subtypes have been confirmed to distribute in human pelvis and calyces recently. As used in ureteral stones, α-blocker treatment may facilitate kidney stone passage and long-term prescription of α-blocker may decrease the risk of recurrent urolithiasis. The aim of this study is to determine if use of α-blockers 180 days or more can decrease the risk of recurrent urolithiasis needed for surgical intervention. Materials and Methods A representative database of 1,000,000 patients from Taiwan’s National Health Insurance was analyzed. Eligible patients were those who had received the first-time procedure for upper urinary stone removal, including extracorporeal shock-wave lithotripsy, ureterorenoscopic lithotripsy, or both, between 2000 and 2010. After completing a 180-day treatment for first event, patients were prospectively followed-up until a second set of stone procedures was performed (proxy of stone recurrence), loss to follow-up, or end of study. The effect of percentage of total number of days of α-blocker use on need for second set of stone procedures within a post treatment 180-day follow-up period was analyzed by quartile. A nested case-control study was also performed. Results 1,259 patients were eligible for final analyses. During 3,980 person-years follow-up, 167 patients had recurrent urolithiasis needed for surgical intervention. From first to fourth quartile of drug exposure, recurrence rates were 45.64, 47.19, 43.11, and 18.52 per 1,000 person-years. The adjusted hazard ratio was 0.46 (95% CI = 0.24 to 0.89) for the fourth quartile (vs. quartile 1). In the nested case-control study, adjusted ORs was 0.23 (95% CI = 0.10 to 0.53) in the fourth quartile (vs. quartile 1). The results remained similar even in patients categorized by cumulative defined daily dose (cDDD) quartiles and average cDDD per day quartiles. Conclusion Use of α-blockers for 180 days or more decrease the risk of recurrent urolithiasis needed for surgical intervention. In patients at higher risk of recurrent urolithiasis, long term prescription of α-blockers might help them prevent further surgical intervention.

Clinical pharmacology is an essential consideration in chronic therapies, and may play a significant role in modifying the pharmacological characteristics of drug formulations. Improvement in drug formulations may ensure their safe and effective use over a period of time. This has been particularly observed with α-1 adrenergic blockers in hypertension management. Advancements in formulations like prazosin GITS, have resulted in improvement in tolerability profile and smoother, more effective blood pressure control, which reasonably translate into improvement in patient compliance and better clinical outcomes.

Abstract
OBJECTIVE To investigate factors associated with demographic/clinical characteristics and drug selection in patients with erectile dysfunction (ED). The prevalence of ED is increasing worldwide. Studies have shown that ED is associated with age, lifestyle and comorbidities. However, the factors associated with patient characteristics as well as drug selection are incompletely understood. SETTING A tertiary medical centre in Kuala Lumpur, Malaysia. PARTICIPANTS A total of 219 patients (range 23-80 years) who had received phosphodiesterase type-5 (PDE-5) inhibitors as ED treatment were evaluated. INCLUSION CRITERIA Adult patients aged ≥18 years, diagnosed with ED, and prescribed with sildenafil, tadalafil or vardenafil. EXCLUSION CRITERIA Patients diagnosed with ED but who did not receive any PDE-5 inhibitor, or those with missing data. PRIMARY AND SECONDARY OUTCOME MEASURES Factors associated with demographic and clinical characteristics as well as drug selection were assessed. RESULTS Ischaemic heart disease (p=0.025), benign prostatic hyperplasia (p<0.001), obesity (p=0.005), lower urinary tract symptoms (LUTS) (p=0.006) and α-blockers (p<0.001) were significantly associated with elderly patients with ED. Additionally, LUTS (p=0.038) and α-blockers (p=0.008) were significantly associated with the selection of PDE-5 inhibitor. CONCLUSIONS These data showed that elderly patients with ED were significantly associated with comorbidities and α-blockers, whereas LUTS and α blockers were associated with drug selection.

Abstract
BACKGROUND AND PURPOSE Prior work aimed at improving our understanding of human cerebral autoregulation has explored individual physiological mechanisms of autoregulation in isolation, but none has attempted to consolidate the individual roles of these mechanisms into a comprehensive model of the overall cerebral pressure-flow relationship. METHODS We retrospectively analyzed this relationship before and after pharmacological blockade of α-adrenergic-, muscarinic-, and calcium channel-mediated mechanisms in 43 healthy volunteers to determine the relative contributions of the sympathetic, cholinergic, and myogenic controllers to cerebral autoregulation. Projection pursuit regression was used to assess the effect of pharmacological blockade on the cerebral pressure-flow relationship. Subsequently, ANCOVA decomposition was used to determine the cumulative effect of these 3 mechanisms on cerebral autoregulation and whether they can fully explain it. RESULTS Sympathetic, cholinergic, and myogenic mechanisms together accounted for 62% of the cerebral pressure-flow relationship (P<0.05), with significant and distinct contributions from each of the 3 effectors. ANCOVA decomposition demonstrated that myogenic effectors were the largest determinant of the cerebral pressure-flow relationship, but their effect was outside of the autoregulatory region where neurogenic control appeared prepotent. CONCLUSIONS Our results suggest that myogenic effects occur outside the active region of autoregulation, whereas neurogenic influences are largely responsible for cerebral blood flow control within it. However, our model of cerebral autoregulation left 38% of the cerebral pressure-flow relationship unexplained, suggesting that there are other physiological mechanisms that contribute to cerebral autoregulation.

Abstract
AIMS To clarify the antiallodynic effects of the α2-adrenergic receptor antagonist mirtazapine compared with those of gabapentin and pregabalin in a rat model of orofacial neuropathic pain. METHODS Mirtazapine (10, 30, and 100 μg), gabapentin (10, 30, and 100 μg), and pregabalin (3, 10, and 30 μg) were administered intrathecally to eight male Sprague-Dawley rats with orofacial neuropathic pain induced by chronic constriction injury of the infraorbital nerve that had been carried out 2 weeks previously. Stimulation using von Frey filaments (1.0 to 15.0 g) applied to skin innervated by the injured infraorbital nerve enabled the measurement of mechanical thresholds 0 to 180 minutes after drug injection. Time-course data for the dose-response effects were analyzed using two-way analysis of variance and the posthoc Tukey-Kramer multiple-comparison test. RESULTS Intrathecal administration of not only gabapentin and pregabalin but also mirtazapine reversed the lowered mechanical nociceptive thresholds produced by the nerve injury. The ED50 (95% confidence interval) was (in μg) 49.00 (39.71-58.29) for mirtazapine, 54.84 (46.12-63.56) for gabapentin, and 13.47 (11.24-15.69) for pregabalin. CONCLUSION Intraspinal administration of either mirtazapine, gabapentin, or pregabalin reverses the lowered facial mechanical thresholds produced in a rat model of trigeminal neuropathic pain.

Abstract
To study the antiarrhythmic effect of the newly developed alpha/beta-blocker TJ0711, a variety of animal models of arrhythmia were induced by CaCl2, ouabain and ischemia/reperfusion. Glass microelectrode technique was used to observe action potentials of right ventricular papillary muscle of guinea pig. The onset time of arrhythmia induced by CaCl2 was significantly prolonged by TJ0711 at 0.75, 1.5 and 3 mg x kg(-1) doses. TJ0711 (1.5 and 3 mg x kg(-1)) can significantly shorten the ventricular tachycardia (VT) and ventricular fibrillation (VF) duration, the incidence of VF and mortality were significantly reduced. On ischemia-reperfusion-induced arrhythmic model, TJ0711 (0.25, 0.5, 1 and 2 mg x kg(-1)) can significantly reduce the ventricular premature contraction (PVC), VT, VF incidence, mortality, arrhythmia score with a dose-dependent manner. At the same time, rats serum lactate dehydrogenase (LDH) and creatine kinase (CK) activities decreased significantly by TJ0711 (1 and 2 mg x kg(-1)). Ouabain could cause arrhythmia in guinea pigs, when TJ0711 (0.375, 0.75, 1.5 and 3 mg x kg(-1)) was given, the doses of ouabain inducing a variety of arrhythmia PVC, VT, VF, cardiac arrest (CA) were significantly increased with a dose-dependent manner. In the TJ0711 0.1-30 micromol x L(-1) concentration range, guinea pig right ventricular papillary muscle action potential RP (rest potential), APA (action potential amplitude) and V(max) (maximum velocity of depolarization) were not significantly affected. APD20, APD50 and APD90 had a shortening trend but no statistical difference with the increase of TJ0711 concentration. TJ0711 has antiarrhythmic effect on the sympathetic nerve excitement and myocardial cell high calcium animal arrhythmia model. Myocardial action potential zero phase conduction velocity and resting membrane potential were not inhibited by TJ0711. APD20, APD50 and APD90 were shortened by TJ0711 at high concentration. Its antiarrhythmic action mechanism may be besides the action of blocking beta1 receptor, may also have a strong selective blocking action on alpha1 receptor and reducing intracellular calcium concentration.

Abstract
The insular cortex (IC) is a limbic structure involved in cardiovascular responses observed during aversive threats. However, the specific neurotransmitter mediating IC control of cardiovascular adjustments to stress is yet unknown. Therefore, in the present study we investigated the role of local IC adrenoceptors in the cardiovascular responses elicited by acute restraint stress in rats. Bilateral microinjection of different doses (0.3, 5, 10 and 15 nmol/100 nl) of the selective α1-adrenoceptor antagonist WB4101 into the IC reduced both the arterial pressure and heart rate increases elicited by restraint stress. However, local IC treatment with different doses (0.3, 5, 10 and 15 nmol/100 nl) of the selective α2-adrenoceptor antagonist RX821002 reduced restraint-evoked tachycardia without affecting the pressor response. The present findings are the first direct evidence showing the involvement of IC adrenoceptors in cardiovascular adjustments observed during aversive threats. Our findings indicate that IC noradrenergic neurotransmission acting through activation of both α1- and α2-adrenoceptors has a facilitatory influence on pressor response to acute restraint stress. Moreover, IC α1-adrenoceptors also play a facilitatory role on restraint-evoked tachycardiac response.

Abstract
Positive and negative emotional experiences induced by addictive drugs play an important role in the development of dysfunctional drug-related memory, which becomes resistant to extinction and contributes to high rate of relapse. Those memories may undergo a process called reconsolidation that in some cases can be disrupted by pharmacological treatment. The basolateral amygdala (BLA) has been shown to mediate the reconsolidation of drug-related appetitive memory, but its role in withdrawal-related aversive memory remains elusive. The present study used conditioned place preference (CPP) and conditioned place aversion (CPA) paradigms to investigate the role of BLA and its noradrenergic receptors in reconsolidation of morphine-associated emotional memory in rats. We found that inhibition of protein synthesis in BLA disrupted the reconsolidation of morphine CPP (m-CPP) and CPA related to morphine withdrawal (m-CPA). A high dose of the β-noradrenergic receptor antagonist propranolol (3 µg) in BLA-impaired reconsolidation of m-CPA but not m-CPP, whereas a low dose (0.3 µg) was ineffective. In contrast, neither low nor high doses of the α-noradrenergic receptor antagonist phentolamine (1 or 10 µg) blocked the reconsolidation of m-CPP and m-CPA. In addition, infusion of propranolol (3 µg) into nucleus accumbens after retrieval of either m-CPP or m-CPA did not affect its reconsolidation. The findings indicate that appetitive and aversive addictive memories share common neural substrates in BLA, but the specific neurotransmitter mechanism on reconsolidation of morphine-associated negative and positive memories can be dissociable.

Abstract
BACKGROUND Laparoscopic approach has become the gold standard for the surgical treatment of suprarenal gland. Nevertheless there is still controversy about the laparoscopic treatment of adrenal carcinoma. MATERIAL AND METHODS From April 2005 to April 2012, 37 laparoscopic adrenalectomies were performed. We describe and analyze retrospectively: age, sex, side, indication for surgery, tumor size, length of hospital stay, complications and conversion rate. RESULTS 37 Patients, 19 male and 18 female, aged 51.72 ± 14.42 years, were operated on between 2005 and 2012. Twenty-two left-sided lesions (59.45%) and 15 right-sided lesions (40.54%) were operated on. The indications for surgery were non-functioning adenoma larger than 4 cm or rapid growth and hormone-secreting tumours. The diagnosis was confirmed in all the cases with computed tomography and or magnetic resonance imaging and also metaiodobenzylguanidine scintigraphy if pheochromocytoma was suspected. In all the cases we realized a complete pre-operative hormonal study. CONCLUSIONS Laparoscopic adrenalectomy is a safe procedure and gold standard technique for suprarenal surgery. Our experience is very satisfactory, with comparable results to the reference standard open approach.

Abstract
AIMS We investigated outcomes after discontinuing alpha-blockers or finasteride in patients who initially received combination therapy and compared differences by duration of combination therapy. METHODS Patients with international prostate symptom score ≥ 8, serum prostatic-specific antigen (PSA) < 4 ng/ml, prostate volume > 25 cm(3) and combination therapy of alpha-blockers and finasteride for more than 6 months were classified into three groups. Group 1 continued combination therapy; group 2, alpha-blockers monotherapy; and group 3, finasteride monotherapy. All parameters were evaluated before and after changing to monotherapy. Patients who received combination therapy for 6-9 months and those who received combination therapy for longer were comparatively analysed. RESULTS Mean age of the 106 patients was 66.9 ± 7.8 years. No significant differences in baseline symptom scores, PSA or prostate volume were found. Following combination therapy, symptom scores, and quality of life (QoL) decreased for all groups. Group 1 maintained decreased PSA and prostate volume, and improved uroflowmetric profiles. No differences in uroflowmetric parameters were found after 6 months. Group 2 maintained improved symptoms, QoL and uroflowmetric profiles, although PSA and prostate volume returned to baseline. Group 3 maintained lowered PSA and prostate volume, whereas Qmax returned to baseline. QoL scores showed no change. Patients who received combination therapy for ≥9 months improved more in symptoms and QoL than those who received shorter combination therapy. CONCLUSIONS Discontinuation of alpha-blockers or finasteride after combination therapy for ≥ 6 months maintained improvements in symptoms. The appropriate period of combination therapy was ≥ 9 months.

Abstract
The efficacy and safety of once-daily 2.5- or 5.0-mg methyclothiazide (MCTZ) added to once-daily 5.0-mg terazosin (TRZ) versus 5.0-mg TRZ alone was evaluated in this double-blind, multicenter study. All patients received TRZ during a 6-week titration period. Hypertensive patients (222) (mean blood pressure of 159/104 mm Hg) were randomized to one of three treatment groups: TRZ alone (N = 76); TRZ+MCTZ-2.5 mg (N = 74); and TRZ+MCTZ-5.0 mg (N = 72) for the 8-week double-blind period. Changes in the supine and standing SBP/DBP from preTRZ period were: TRZ alone (-4.8/-8.1 and -2.6/-6.1 mm Hg); TRZ+MCTZ-2.5 mg (-17.3/-12.4 and -16.0/-11.2 mm Hg); and TRZ+MCTZ-5.0 mg (-20.6/-14.4 and -23.3/-14.6 mm Hg). Blood pressure changes in the combination groups were significantly greater than those in the TRZ alone group. However, there were no statistically significant differences between the TRZ+MCTZ-2.5-mg and TRZ+MCTZ-5.0-mg groups. The combination of TRZ and MCTZ tends to mitigate the adverse effects on serum glucose, uric, potassium and lipids usually associated with thiazide diuretics. Thus, combination treatment that begins with TRZ and adds MCTZ is effective in lowering blood pressure without any significant adverse metabolic effects.

Abstract
Tolazoline is an α2-adrenergic receptor antagonist, used in veterinary medicine to antagonize the central nervous system depressant and cardiovascular effects of α2 receptor agonists. The pharmacokinetics and pharmacodynamic effects of tolazoline when administered subsequent to detomidine in the horse were recently reported, although the reversal of the sedative and cardiovascular effects following detomidine may not be complete. The current study therefore investigated the pharmacokinetics and pharmacodynamic effects of tolazoline when administered as a sole agent. Nine healthy adult horses were administered tolazoline (4mg/kgIV) and blood samples were collected at time 0 (prior to drug administration) and at various times up to 72h post drug administration. Plasma samples were analyzed using liquid chromatography-mass spectrometry and resulting data analyzed using compartmental analysis. Systemic clearance, steady state volume of distribution and terminal elimination half-life were 0.820±0.182L/h/kg, 1.68±0.379L/kg and 2.69±0.212h, respectively. Tolazoline administration had no effect on chin to ground distance, but the heart rate decreased (relative to baseline) and the percentage of atrial-ventricular block increased in all horses within 2min of administration. Packed cell volume and glucose concentrations were also increased throughout the sampling period. While not commonly used as a sole agent, caution is indicated whenever tolazoline is administered since the effects may be unpredictable.

Abstract
AIMS/HYPOTHESIS Fatty acid entrapment in femoral adipose tissue has been proposed to prevent ectopic fat deposition and visceral fat accumulation, resulting in protection from insulin resistance. Our objective was to test the hypothesis of femoral, compared with abdominal, adipose tissue resistance to adrenergic stimulation in vivo as a possible mechanism. METHODS Regional fatty acid trafficking, along with the measurement of adipose tissue blood flow (ATBF) with (133)Xe washout, was studied with the arteriovenous difference technique and stable isotope tracers in healthy volunteers. Adrenergic agonists (isoprenaline, adrenaline [epinephrine]) were infused either locally by microinfusion or systemically. Local microinfusion of adrenoceptor antagonists (propranolol, phentolamine) was used to characterise specific adrenoceptor subtype effects in vivo. RESULTS Femoral adipose tissue NEFA release and ATBF were lower during adrenaline stimulation than in abdominal tissue (p < 0.001). Mechanistically, femoral adipose tissue displayed a dominant α-adrenergic response during adrenaline stimulation. The α-adrenoceptor blocker, phentolamine, resulted in the 'disinhibition' of the femoral ATBF response to adrenaline (p < 0.001). CONCLUSIONS/INTERPRETATION Fatty acids, once stored in femoral adipose tissue, are not readily released upon adrenergic stimulation. Femoral adipose tissue resistance to adrenaline may contribute to the prevention of ectopic fatty acid deposition.

Abstract
CONTEXT AND OBJECTIVES Artocarpus altilis (Parkinson) Fosberg (Moraceae) (breadfruit) leaves are used as an antihypertensive remedy. We investigated the possible mechanisms of action of its aqueous extract and its effect on cytochromes P450 (CYP) enzyme activities. MATERIALS AND METHODS Intravenous administration of an aqueous leaf extract (20.88-146.18 mg/kg) of A. altilis on mean arterial pressure and heart rate were recorded via cannulation of the carotid artery on anaesthetized normotensive Sprague-Dawley rats. Recordings of the contractile activity of the aortic rings to the extract (0.71-4.26 mg/mL) were studied using standard organ bath techniques. Inhibitions of human CYP3A4 and CYP2D6 enzyme activities were evaluated by means of a fluorometric assay in 96 well plates using heterologously expressed microsomes. RESULTS A. altilis caused significant (p < 0.05) hypotensive and bradycardiac responses unaffected by atropine (2 mg/kg) and mepyramine (5 mg/kg), but attenuated by propranolol (1 mg/kg) and N(G)-nitro-L-arginine methyl ester (5 mg/kg). The extract (0.71-4.26 mg/mL) significantly (p < 0.05) relaxed phenylephrine (10⁻⁹-10⁻⁴ M) and 80 mM KCl-induced contractions in endothelium intact and denuded aortic rings; and caused a significant (p < 0.05) rightward shift of the Ca²⁺ dose-response curves in Ca²⁺-free Kreb's solution. Moderate inhibitions of cytochrome P450s (CYP3A4 and CYP2D6) enzyme activities with IC₅₀ values of 0.695 ± 0.187 and 0.512 ± 0.131 mg/mL, respectively, were produced. CONCLUSION A. altilis exhibits negative chronotropic and hypotensive effects through α-adrenoceptor and Ca²⁺ channel antagonism. Drug adversity effects are unlikely if the aqueous leaf extract is consumed with other medications reliant on CYP3A4 and CYP2D6 metabolism. This study thus provides scientific evidence for the use of the breadfruit in the treatment of hypertension.

Abstract
We investigated the add-on effect of dutasteride (0.5 mg once a day) on lower urinary tract symptoms (LUTS), prostate volume (PV), and serum prostate specific antigen (PSA) and testosterone level in 72 patients with benign prostatic hyperplasia (BPH) who had been treated with alpha-blocker monotherapy. Inclusion criteria were men with BPH who had PV ≧30 ml and international prostate symptom score (IPSS) ≧8 or quality of life (QOL) index ≧3 under alpha-blocker monotherapy for more than 3 months. At the baseline, 12 and 24 weeks after dutasteride add-on, we assessed IPSS, overactive bladder symptom score (OABSS), PV, serum PSA and testosterone. Among 47 patients (65%) with OAB diagnosed by OABSS, responders were defined as those with urgency score of OABSS <2 or total score of OABSS <3. At the 24th week, dutasteride significantly improved IPSS (-4.2) and OABSS (-1.9) and reduced PV (-29%) compared with the baseline. Furthermore, dutasteride significantly decreased serum PSA (-45%) and increased testosterone (36%). Among OAB patients, dutasteride significantly improved urgency and urgency incontinence but not nocturia. Responders had lower OABSS, urgency incontinence score and serum testosterone at the baseline than non-responders. In conclusion, dutasteride add-on therapy is beneficial in patients with BPH who do not show enough improvement with alpha-blocker monotherapy.

Abstract
This case report describes a successful outcome of mirtazapine treatment in a patient with difficult post-thoracotomy pain. A 63-year-old man received thoracotomy for the resection of esophageal tumor. The pain continued 2 years after the operation. Allodynia was present in the region of the intercostal nerves from the surgical wound. Remedies such as clonazepam, amitriptyline, gabapentin, and acetaminophen were not effective, and epidural block effect was only temporal. The patient experienced a reduction in shooting pain after taking pregabalin; however, he still suffered from persistent pain and, mirtazapine was additionally administrated. One month after this, shooting and persistent pain was reduced, and the patient's appetite was improved, which had been present since the thoracotomy. Since then, his weight slightly increased and the administration of mirtazapine was stopped in accordance with the patient's request. The pain became worse again. Therefore, mirtazapine, commonly used as an antidepressant agent, was considered to be beneficial for neuropathic pain as an analgesic adjuvant.

Abstract
BACKGROUND Alpha blockers are occasionally prescribed for hypertension so it is important to determine and compare their effects on blood pressure (BP), heart rate and withdrawals due to adverse effects (WDAE). OBJECTIVES To quantify the dose-related systolic and/or diastolic BP lowering efficacy of alpha blockers versus placebo in the treatment of primary hypertension. SEARCH METHODS For the updated review, we searched CENTRAL (The Cochrane Library 2012, Issue 4), MEDLINE (1946 to May 2012), EMBASE (1980 to May 2012) and reference lists of articles. SELECTION CRITERIA Double-blind, randomized, controlled trials evaluating the BP lowering efficacy of fixed-dose monotherapy with an alpha blocker compared with placebo for a duration of 3 to 12 weeks in patients with primary hypertension. DATA COLLECTION AND ANALYSIS Two authors independently assessed the risk of bias and extracted data. Study authors were contacted for additional information. WDAE information was collected from the trials. MAIN RESULTS Only 10 trials evaluated the dose-related trough BP lowering efficacy of 4 different alpha blockers in 1175 participants with a baseline BP of 155/101 mm Hg. The data do not suggest that any one alpha blocker is better or worse at lowering BP. The best but unsatisfactory estimate of the trough BP lowering efficacy for alpha blockers is -8/-5 mmHg. AUTHORS' CONCLUSIONS Based on the limited number of published RCTs, the BP lowering effect of alpha blockers is modest; the estimate of the magnitude of trough BP lowering of -8/-5 mmHg is likely an overestimate. There are no clinically meaningful BP lowering differences between different alpha blockers. The review did not provide a good estimate of the incidence of harms associated with alpha blockers because of the short duration of the trials and the lack of reporting of adverse effects in many of the trials.

Abstract
Our study included 50 patients aged 48-67 years with moderate symptoms of prostatic adenoma (PA). Thirty patients received vitaprost-forte in the form of rectal suppositories for 60 days and alpha-adrenoblocker. A positive effect of the drug on PA symptoms and improvement of life quality by IPSS and QoL questionnaires was observed in 93.3% patients. Relief of infravesical obstruction led to a 43% reduction of residual urine. The effect was stable on day 30 after the treatment. Our findings evidence that vitaprost forte can be successfully and safely used in the treatment of PA in combination with alpha-adrenoblockers.

Abstract
Of late, we observe a trend to a progressive rise of overactive bladder (OB) morbidity with age. M-cholinolytic drugs are most effective in management of OB but old patients with prostatic adenoma (PA) and comorbid pathology have a risk of acute urinary retention and serious side effects. We have the experience in combined treatment of 30 old patients with PA and OB with M-cholinolytic and alpha-adrenoblocker. The results of the treatment show its efficacy and absence of complications in the control of residual urine for 3 months. Combination of M-cholinolytic with alpha-adreboblocker significantly reduced daily diuresis, improved an accumulation function of the bladder and life quality.

Abstract
UNLABELLED Treatment of benign prostate hyperplasia with α-blockers may affect blood pressure while treatment with 5-α-reductase inhibitors may affect conversion of testosterone potentially leading to osteoporosis. In our study, neither 5-α-reductase inhibitors nor α-blockers were associated with negative effects on fractures, α-blockers perhaps being associated with a limited decrease in fractures. INTRODUCTION The objective is to study fracture risk associated with drugs for benign prostate hyperplasia. The hypotheses were that (1) α-blockers may elevate fracture risk by causing presyncope/falls and (2) 5-α-reductase inhibitors may elevate fracture risk by lowering dihydrotestosterone. METHODS This is a nationwide case-control study using all 9,719 male fracture patients aged ≥60 years in the year 2000 as cases and drawing 29,156 age- and gender-matched controls. The main exposure was the use of the drugs mentioned above for benign prostate hyperplasia. Confounder control included social variables, contacts to hospitals and general practitioners, alcoholism and other variables. RESULTS For the 5-α-reductase inhibitors, no change in overall risk of fractures was seen. No change in risk of hip, spine and forearm fractures was present. For the α-blockers, a decrease in overall risk of fractures was seen, as well as a decrease in the risk of hip and spine fractures, but only at average doses >0.5 defined daily doses per day. No decrease was seen for forearm fractures. A decreasing risk of any fracture, hip fractures and spine fractures were seen with increasing dose of α-blockers, while no such association was seen for the forearm fractures. CONCLUSION Neither the 5-α-reductase inhibitors nor α-blockers were associated with negative effects on fracture risk. A small trend towards a decrease in fracture risk may be present for the α-blockers. However, more research is needed to confirm if this trend is real.

Abstract
The efficacy and safety of additional administration of propiverine were prospectively studied for naftopidil-resistant nocturia in patients with benign prostatic hypertrophy (BPH). Patients of 50 years and over with BPH who experienced nocturia twice a night or more and an overall International Prostate Symptom Score (IPSS) of 8 or more were first administered naftopidil (50 or 75 mg/day) for 4 weeks. Thirty subjects who did not show improvement in nocturia and requested further treatment were enrolled in the present study. Propiverine was then administered concomitantly 10 mg/day for 8 weeks. Significant improvement was observed with additional propiverine in the frequency of nocturia on voiding diary, total IPSS, voiding symptom, storage symptom and nocturnal voiding scores. No significant change was observed in the peak urinary flow rate (Qmax), mean urinary flow rate (Qave), voided urine volume, or residual urine volume. Adverse events were dysuria (2 cases), increased residual urine (6 cases), weak urine flow (1 case), thirsty (2 cases), angular cheilitis (1 case). Administration of propiverine was suspended in 7 subjects, 1 following dysuria and 6 following increased residual urine volume. The suspension of propiverine following increased residual urine volume was significantly more prevalent in subjects with pretreatment Qmax values of less than 10 ml/second or in subjects whose prostate specific antigen (PSA) levels were 2 ng/ml or more. In conclusion, the results indicate that additional administration of propiverine may be useful for the patients with BPH who have naftopidil-resistant nocturia. However, caution must be exercised regarding Qmax and PSA levels.

Abstract
A total of 100 patients with benign prostatic hyperplasia (BPH) and overactive bladder (OAB) symptoms (BPH/OAB), enrolled between June 2006 to March 2008, were randomly divided into 2 groups of morning medication (M) and evening medication (E) groups, then 50 mg of naftopidil was given once a day after breakfast or supper for 8 weeks. Data were available for efficacy analysis on 80 patients (M group ; 43, E group ; 37). Naftopidil significantly improved the overall international prostatic symptom score ; from 19.2±7.9 to 11.7±5.8 in the M group and from 19.4±6.4 to 12.3±6.8 in the E group (p<0.0001), QOL score from 4.9±0.8 to 3.2±1.4 in the M group and from 5.0±0.8 to 3.6±1.3 in the E group (p<0.0001), and OAB symptom score from 7.8±2.6 to 5.0±2.5 in the M group (p<0.0001) and from 8.6±2.9 to 5.8± 3.3 in the E group (p<0.0001). There was no significant difference in the incidence of adverse effects between the M group (6.1%) and E group (2.2%). These results suggest that naftopidil improves storage symptoms as well as voiding symptoms regardless of timing of administration.

Abstract
The objective of this article is to evaluate the efficacy of Doxazosin Mesylate Controlled Release Tablets for preoperative treatment of patients with pheochromocytoma. Between 2003 and 2008, 67 patients with confirmed diagnoses of pheochromocytoma were enrolled in this study. According to the drug used in preoperative management, patients were divided into two groups: Doxazosin Mesylate pretreatment group (n=36) and Phenoxybenzamine pretreatment group (n=31). Surgery was performed only in patients who met the optimal preoperative condition. The hematocrit decreased significantly (P<0.001) after antiadrenergic therapy in patients pretreated with phenoxybenzamine or doxazosin. There was no significant difference between the fluid intakes during operation in both groups. The systolic arterial pressures both before and after induction of anesthesia were all significantly higher in the doxazosin patients than in the phenoxybenzamine group (P<0.05). After tumor removed, the lowest systolic arterial pressure was significantly higher in doxazosin group than in phenoxybenzamine group (P<0.05). The fluctuation of systolic arterial pressure during operation was more stable in doxazosin group than in phenoxybenzamine group (P<0.05). Doxazosin mesylate controlled release tablet was as effective as phenoxybenzamine in preoperative volume expansion. Although phenoxybenzamine provided better arterial pressure control, patients pretreated with DOX experienced more stable perioperative hemodynamic changes, shorter preoperative management periods and more simple medication.
