We evaluated the effectiveness of tamsulosin monotherapy versus tamsulosin plus sildenafil combination therapy on erectile dysfunction (ED) in young patients with type III chronic prostatitis and ED by using symptom score scales. 44 male patients were divided into 2 groups: the first group (20 patients) was treated with tamsulosin 0,4 mg monotherapy and the second one 24 patients) was treated with tamsulosin 0,4 mg plus sildenafil 50 mg combination therapy. “International Prostate Symptom Score, “National Institute of Health Chronic Prostatitis Symptom Index" (NIH-CPSI) and “International Index of Erectile Function" (IIEF-5) were investigated in each group of patients, and scores calculated during the first medical examination. Both groups were treated with tamsulosin once daily for 60 days, while sildenafil 50 mg was given on demand (at least 2 times per week) for 60 days. During the second medical examination IPSS, NIH-CPSI and IIEF-5 scores were analyzed once more. Afterwards, the alterations of scores among medical examinations in each group and between both groups were statistically compared. The age average of the 44 cases included was 32.04 3.15 years. Both groups present a statistically significant decrease, between the first and the second medical examination, in IPSS, NIH-CPSI scores and statistically significant increase in IIEF-5 score. In addition, there is no statistically significant difference, in all scores, between mono and combination therapy. tamsulosin monotherapy, as well as a combination therapy (tamsulosin plus sildenafil) has an improving effect on symptoms and on ED in patients with type III prostatitis. In the near future alpha-blockers monotherapy could be used in the treatment of chronic prostatitis and ED cases instead of phosphodiesterase type 5 (PDE-5) inhibitors combination therapy.

Tamsulosin and mirabegron may be used concomitantly in patients with lower urinary tract symptoms. Since alpha1-adrenoceptor antagonists are associated with cardiovascular side effects, potential pharmacokinetic and cardiovascular interactions were evaluated. This was an open-label, randomized, 2-arm, 2-sequence study in 48 healthy men (24/arm) aged 44 - 72 years. In arm 1, subjects received single-dose tamsulosin hydrochloride modified release capsules (0.4 mg) alone and with steady-state mirabegron oral controlled absorption system tablets (100 mg once daily) in random sequence. In arm 2, subjects received single-dose mirabegron alone and with steady-state tamsulosin. Samples for mirabegron and tamsulosin plasma concentrations were collected. Blood pressure (BP) and pulse rate (PR) were measured and orthostatic stress tests were performed. Mirabegron increased tamsulosin C(max) to 159% (90% confidence interval (CI) 143 - 177%), AUC(∞) to 161% (90% CI 149 - 173%), and t(1/2) to 116%. Tamsulosin reduced mirabegron C(max) to 85% (90% CI 71 - 103%) and AUC(∞) to 84% (90% CI 74 - 95%) without effect on t1/2. Mirabegron and tamsulosin co-treatment caused no statistically significant changes (p > 0.05) in PR or systolic BP versus mono-treatment up to 12 hours post-dose. Mean diastolic BP decreases of -2.1 (95% CI -4.1, -0.1) to -4.2 (-7.5, -0.9) mmHg in arm 1 and -3.0 (-5.7, -0.3) to -4.2 (-7.4, -1.0) mmHg in arm 2 were observed, statistically significant (p tamsulosin to existing tamsulosin or mirabegron therapy did not cause clinically relevant changes in cardiovascular safety or safety profiles.

To determine if a pharmacological test could be developed to determine iris dilator dysfunction in patients taking tamsulosin. Patients taking tamsulosin and controls were recruited from the Urology and Ophthalmology clinics at the Montefiore Medical Center. The patient's right eye (OD) was dilated with phenylephrine hydrochloride 2.5% and tropicamide 1%. The patient's left eye (OS) was dilated with tropicamide 1% alone. Forty minutes after dilation, pupillary diameter was measured in both eyes. Thirty-eight tamsulosin subjects and 43 controls met the inclusion criteria for the study. The tamsulosin-treated patients dilated less with phenylephrine than controls (0.61±0.4 vs. 1.10±0.45 mm, respectively Ptamsulosin patients relative to controls shows a greater area under the curve for differential dilation (0.8 vs. 0.6, respectively). A correlation between smooth muscle dysfunction and length of time on tamsulosin was observed. Patients using tamsulosin for tamsulosin for >1 month had an average OD-OS difference of 0.52±0.32 mm (Ptamsulosin demonstrated a significantly decreased iris dilatory response to the selective adrenergic effects of phenylephrine compared to controls. Additionally, it appears that longer duration of exposure to tamsulosin increases the likelihood of dilator dysfunction.

The food supplement quercetin is used as self-medication for prostate disorders and is known to induce vasorelaxation. The drug tamsulosin is used in the treatment of benign prostatic hyperplasia. A major side effect of tamsulosin is orthostatic hypotension, mediated by vasorelaxation resulting from α1-adrenoceptor blockade. The overlapping profile prompted us to investigate the pharmacodynamic interaction of quercetin with tamsulosin. Since quercetin is extensively metabolized in the intestines and the liver, the metabolites quercetin-3-glucuronide and 4'O-methyl-quercetin were also examined. Vasorelaxation induced by the compounds was tested in rat mesenteric arteries (average diameter: 360±μm) constricted by the α1-adrenoceptor agonist phenylephrine. Tamsulosin (0.1nM) decreased phenylephrine sensitivity 17-fold (n=10). Quercetin (5, 10 and 20µM) also caused a decrease (2-, 4- and 6-fold respectively) of phenylephrine sensitivity, while 10µM of quercetin-3-glucuronide and 4'O-methyl-quercetin decreased this sensitivity (1.5- and 2-fold) only slightly (n=6). The combination of tamsulosin with quercetin or quercetin metabolites proved to be far more potent than the compounds in isolation. The combination of quercetin, quercetin-3-glucuronide or 4'O-methyl-quercetin with tamsulosin decreased the phenylephrine sensitivity approximately 200-, 35- and 150-fold (n=6). The strong pharmacodynamic interaction between the food supplement quercetin and tamsulosin underlines the potential of the impact of supplement-drug interactions that warrant more research.

The combination of dutasteride and tamsulosin may be more effective for the treatment of symptomatic benign prostatic hyperplasia than either treatment alone. We report the results of three pharmacokinetics and tolerability studies, which used a dutasteride/tamsulosin HCl (0.5 mg/0.2 mg) fixed-dose combination (FDC) capsules containing a small dutasteride soft gelatin capsule (smaller than commercial Avodart™) and modified-release tamsulosin pellets that have different amounts of enteric coating. These studies compared the test products to commercial Avodart™ (dutasteride 0.5 mg) and two different commercial tamsulosin HCl 0.2 mg products, Harnal™ Capsules or Harnal-D™ Tablets, which are reportedly bioequivalent to each other. All three studies were randomized single-dose studies in healthy male adults. Study 1 [N = 86 (NCT01254071)] was a two-period crossover study of a dutasteride/tamsulosin HCl FDC versus coadministered Avodart™ and Harnal-D™ Tablets. The pharmacokinetics of both dutasteride and tamsulosin were studied. Study 2 [N = 27 (NCT01471678)] was a four-period crossover study of dutasteride/tamsulosin HCl FDC formulations versus Avodart™ and Harnal™ Capsules or Harnal-D™ Tablets. Only the pharmacokinetics of tamsulosin were studied. Study 3 [N = 40 (NCT01495026)] was a two-period study of dutasteride/tamsulosin HCl FDC formulations versus coadministered Avodart™ and Harnal-D™ Tablets. In this study, only the pharmacokinetics of tamsulosin were studied. Study 2 assessed fed-state pharmacokinetics. Studies 1 and 3 assessed fed- and fasted-state pharmacokinetics. All dutasteride/tamsulosin HCl FDC formulations and coadministered treatments were well-tolerated. In Study 1, the FDC dutasteride was bioequivalent to Avodart™ coadministered with tamsulosin under fed and fasted conditions. In Study 1, the FDC tamsulosin had a slower release than commercial Harnal-D™ Tablets coadministered with dutasteride (fed and fasted

Combined therapy of benign prostatic syndrome (BPS) with α 1 -blockers and 5α-reductase (5AR)-inhibitors is recommended according to two leading studies on doxazosin/finasteride and tamsulosin/dutasteride for all 10 in Germany possible combinations (five α 1 -blockers and two 5AR inhibitors). Because tamsulosin and finasteride predominate in the treatment of BPS in Germany, the role of the combination tamsulosin/finasteride and its scientific basis from clinical studies has been investigated. A pharmacoepidemiological extrapolation from receipts of pharmacy data centres showed a strong increase of the combination tamsulosin/finasteride since 2003. As a free combination, tamsulosin/finasteride beside the fixed combination tamsulosin/dutasteride accounts to about 50% of all α 1 -blocker/5AR-inhibitor combinations today. Clinical studies on tamsulosin/finasteride have been published including controlled studies of the combination and both monotherapies. The results of improvement of lower urinary tract symptoms (LUTS), maximum urinary flow rate (Q max ), prostate volume (PV) and prostate-specific antigen (PSA) as well as adverse events and drug safety are in agreement with the leading studies. However, results due to chance cannot be excluded because of deficiencies in study design. A reliable comparison of the risk of progression between tamsulosin/finasteride and both monotherapies is lacking completely. Because of the great coherence and continuous evaluation of available data of all combinations, and with the established strong class effect of monotherapies, a continuation of the therapeutic practice with the combination tamsulosin/finasteride is possible.

The purpose of this study was to evaluate the effect of tamsulosin (0.2 mg) on the pharmacokinetics of dutasteride (0.5 mg) in a group of healthy Chinese male volunteers. This was an open-label, single-sequence, 3-period, drug-drug interaction phase 1 study. Twenty-four healthy Chinese male volunteers were enrolled and administered a single dose of 0.5 mg dutasteride and, following a 28- to 30-day washout period, 0.2 mg tamsulosin once daily for 7 days. On day 5, subjects received 0.2 mg tamsulosin coadministered with 0.5 mg dutasteride. Serum dutasteride and tamsulosin concentrations were monitored. In the presence or absence of tamsulosin, there were no apparent changes in dutasteride AUC and Cmax . Adverse events reported were mild to moderate in intensity and resolved by the end of the study. In healthy Chinese male volunteers, tamsulosin 0.2 mg at steady state had no apparent effect on dutasteride pharmacokinetics. Dutasteride and tamsulosin when administered alone or in combination were well tolerated. © 2015, The American College of Clinical Pharmacology.

Tamsulosin is associated with increased passage of ureteral stones in adults but its effectiveness in children is uncertain. We determined the association between tamsulosin and the spontaneous passage of ureteral stones in children. We performed a multi-institutional retrospective cohort study of patients 18 years or younger who presented between 2007 and 2012 with ureteral stones up to 10 mm and who were treated with tamsulosin or oral analgesics alone. The outcome was spontaneous stone passage, defined as radiographic clearance and/or patient report of passage. Subjects prescribed tamsulosin were matched with subjects prescribed analgesics alone, using nearest neighbor propensity score matching to adjust for treatment selection. Conditional logistic regression models were used to estimate the association between tamsulosin and spontaneous passage of ureteral stones, adjusting for stone size and location. Of 449 children with ureteral stones 334 were eligible for inclusion, and complete data were available for 274 patients from 4 institutions (99 receiving tamsulosin, 175 receiving analgesics alone). Following case matching, there were no differences in age, gender, weight, height, stone size or stone location between the 99 subjects prescribed tamsulosin and the 99 propensity score matched subjects prescribed analgesics alone. In the tamsulosin cohort 55% of ureteral stones passed, compared to 44% in the analgesics alone cohort (p=0.03). In multivariate analysis adjusting for stone size and location tamsulosin was associated with spontaneous passage of ureteral stones (OR 3.31, 95% CI 1.49-7.34). The odds of spontaneous passage of ureteral stones were greater in children prescribed tamsulosin vs analgesics alone. Copyright © 2014 American Urological Association Education and Research, Inc.

In Korea, increasing attention has recently been given to the use of phytotherapeutic agents to alleviate the symptoms of BPH. Serenoa repens has been shown to have an equivalent efficacy to Finasteride or Tamsulosin in the treatment of BPH in previous studies. The present study was designed to compare the efficacy and safety of Serenoa repens plus tamsulosin with tamsulosin only over 12 months in men with LUTS secondary to BPH. One hundred forty men with symptomatic BPH (IPSS≥10) were recruited in our hospital for a 12-month, open-label, randomized trial. Patients were randomly assigned to either tamsulosin 0.2 mg/day plus Serenoa repens 320 mg/day (n=60) or tamsulosin 0.2 mg/day only (n=60). Prostate volume and PSA were measured at baseline and at end-point, whereas total IPSS, and its storage and voiding subscores, LUTS-related QoL, Qmax, and PVR were evaluated at baseline and later every 6 months. Total 103 patients were finally available: 50 in the TAM+SR group and 53 in the TAM group. At 12 months, total IPSS decreased by 5.8 with TAM+SR and 5.5 with TAM (p=0.693); the storage symptoms improved significantly more with TAM+SR (-1.7 vs. -0.8 with TAM, p=0.024). This benefit with regard to storage symptom in the TAM+SR group lasts at 12 months (-1.9 vs. -0.9, p=0.024). The changes of voiding subscore, LUTS-related QoL, Qmax, PVR, PSA, and prostate volume showed no significant differences between the TAM+SR and TAM groups. During the treatment period, 8 patients (16.9%) with TAM and 10 (20%) with TAM+SR had drug-related adverse reactions, which included ejaculatory disorders, postural hypotension, dizziness, headache, gastro-intestinal disorders, rhinitis, fatigue and asthenia. The combination treatment of Serenoa repens and tamsulosin was shown to be more effective than tamsulosin monotherapy in reducing storage symptoms in BPH patients after 6 months and up to 12 months of treatment. © 2015 S.

The aim of this paper is to compare the efficacy of tamsulosin, oxybutynin or their combination for the treatment of symptoms related to double J stent (DJS). Randomized clinical non-blinded trial with three arms (tamsulosin, oxybutynin or combination) to assess the improvement of ureteral related symptoms with DJS with the questionnaire of Ureteral Stent Symptom Questionnaire (USSQ) and the adverse effects of treatment. Evaluations were made at 7 and 21 days after the placement of DJS. The maneuvers were compared using Chi squared test, Kruskall-Wallis, ANOVA and Wilcoxon considering a statistically significant p ≤ 0.05. 170 patients with CJJ were evaluated. A perprotocol analysis was performed in 142 patients, 53 received tamsulosin (37.4%), 42 oxybutynin (29.6%) and 47 the combination of both (33%). At 7 and 21 days the improvement was similar in all three arms. Men with tamsulosin and women with oxybutynin had less general symptoms. Tamsulosin, oxybutynin or its combination similarly improve ureteral stent related symptoms and this improvement becomes more noticeable over time. Men are less symptomatic with tamsulosin and women with oxybutynin.

Tamsulosin has been used for the off-label treatment of lower urinary tract symptoms (LUTS) in women. Over the past few years, several randomized controlled trials (RCTs) have reported the clinical effectiveness and safety of tamsulosin for LUTS in women. Therefore, the aim of the present study was to perform a meta-analysis to evaluate the safety and efficacy of tamsulosin in treating LUTS in women, which may resolve some of the current controversies over use of the drug and provide more reliable evidence for the use of tamsulosin. A literature review was performed to identify all published RCTs of tamsulosin for the treatment of LUTS in women. The search included the following databases: PUBMED, EMBASE, the Cochrane Controlled Trail Register of Controlled Trials, Chinese Biomedical Literature Database, China National Knowledge Infrastructure, Chinese Science and Technique Journals Database (VIP) and Wanfang Database. A systematic review and meta-analysis were conducted. Six RCTs studies involving 764 female participants were included in the analysis. Four out of the six RCTs compared tamsulosin with placebo, one RCT compared tamsulosin with prazosin and the other study compared tamsulosin with tamsulosin combined with tolterodine. Two RCTs evaluated total International Prostate Symptom Score (IPSS) and improved total IPSS compared with the placebo (standardized mean difference=-4.08, 95% confidence interval=-5.93 to -2.23, Ptamsulosin improved the Overactive Bladder Questionnaire score when compared with placebo in only one RCT. For urodynamic parameters, tamsulosin improved the average flow rate and the post-void residual volume when compared with prazosin and tolterodine combined with tamsulosin, respectively. Beyond that, the other parameters showed no significant difference between the treatment and control groups. On the basis of the present evidence, tamsulosin is an effective treatment for the relief of LUTS in women when compared with placebo. However

Medical expulsive therapy represents an effective adjunctive treatment for nonpregnant patients with symptomatic urolithiasis. Tamsulosin is classified by the FDA (Food and Drug Administration) as a category B medication. However, to our knowledge no published data exist for human pregnancy. We explored the safety and efficacy of tamsulosin therapy for symptomatic urolithiasis occurring during pregnancy. We retrospectively identified patients treated with tamsulosin for stone disease during pregnancy at the Mayo Clinic during 2000 to 2014. This medical expulsive therapy cohort was matched 2:1 to pregnant women with symptomatic urolithiasis during pregnancy who did not receive medical expulsive therapy. Groups were compared using linear mixed models for continuous variables and exact conditional logistic regression models for nominal variables to take into account correlation due to matching. A total of 27 patients receiving medical expulsive therapy comprised the study cohort. Median duration of antepartum tamsulosin exposure was 3 days (range 1 to 110), occurring during the first, second and third trimester in 3 (11%), 11 (40.7%) and 18 (67%) patients, respectively. Mean gestational age at delivery was 38.1 weeks (SD 2.4) and 6 (22%) infants were born preterm. All infant birthweights were considered appropriate for gestational age, and no cases of spontaneous abortion, intrauterine demise or neonatal congenital anomalies were encountered. Comparison between the medical expulsive therapy and control groups demonstrated no significant differences in maternal or infant outcomes for any of the examined variables. Tamsulosin medical expulsive therapy does not appear to be associated with adverse maternal or fetal outcomes and may be considered as adjunctive therapy for urolithiasis during pregnancy.

The purpose of the study was to assess the impact of dutasteride plus tamsulosin combination therapy, compared with dutasteride or tamsulosin monotherapy, on nocturia in men with lower urinary tract symptoms suggestive of benign prostatic hyperplasia (LUTS/BPH) using data from the 4-year CombAT study. Nocturia was assessed using Question 7 of the International Prostate Symptom Score questionnaire. Efficacy measures included as follows: mean change in nocturia at 3-month intervals up to 48 months; proportion of patients with improvement/worsening in nocturia; nocturnal voiding frequency at baseline and study end, overall and by baseline subgroups; and nocturnal voiding frequency tamsulosin -0.3). Reduction in nocturia score with combination therapy was significantly (p ≤ 0.01) better than tamsulosin monotherapy across all baseline subgroups tested, except for men with previous 5ARI use. Among those with a baseline IPSS Q7 score ≥ 2, more patients with combination therapy had a score tamsulosin (26 %, p tamsulosin monotherapies. These analyses are the first to show greater improvement with a 5ARI/α-blocker combination versus either agent alone for the management of nocturia in patients with LUTS/BPH.

To determine the efficacy and safety of the adrenergic alpha-antagonist tamsulosin in facilitating ureteral stones expulsion. A literature search was carried out using the PubMed database, Medline via Ovid, Embase and the Cochrane Library database to identify randomized controlled trials evaluating the efficiency of tamsulosin in the treatment of ureteral stones. Meta-analysis and forest plots were carried out by use of Review Manager version 5.1 software (Cochrane Collaboration). Compared with the control group, the tamsulosin group had an increase in expulsion rate of 51% and a decrease in expulsion time of 2.63 days. Furthermore, tamsulosin was found to reduce the risk of ureteral colic during treatment by 40% and also the risk of requirement of auxiliary procedures during follow up by 60%. In terms of safety, the tamsulosin group had a 117% increase in the incidence of side-effects compared with the control group, especially for incidence of dizziness. Tamsulosin facilitates the expulsion of ureteral calculi by providing a higher expulsion rate, a shorter expulsion time, a lower incidence of ureteral colic during treatment and a lower requirement of auxiliary procedures. However, the incidence of dizziness occurring during tamsulosin treatment is significantly higher in this setting. © 2012 The Japanese Urological Association.

In the United States, urolithiasis affects approximately 1 in 11 people, and there is evidence that the prevalence is increasing. A relatively recent treatment strategy for urolithiasis involves using medical expulsive therapy (MET) to increase the likelihood of spontaneous passage of ureteral stones. The 2 leading drug classes for MET are alpha-1-andrenergic receptor blockers and calcium channel blockers. Tamsulosin, an alpha-1-adrenocepter blocking agent, is thought to induce spontaneous stone passage by relaxing ureteral smooth muscle tone. However, tamsulosin has not been proven effective for increasing ureteral stone passage and is not approved by the Food and Drug Administration for this indication. There is a relative paucity of data on the efficacy of tamsulosin for urolithiasis, and of the published results, there are conflicting conclusions from the data. Because of the acute and often severe nature of symptoms from urolithiasis, emergency medicine physicians are frequently the first to diagnose and treat this condition. This has led to tamsulosin being frequently prescribed from the emergency department (ED) for off-label use without the support of high-quality evidence. If tamsulosin is proven effective, its use in the treatment of urolithiasis could offer several important advantages. The number of procedures, length of hospital stay, and health care costs after the initial ED visit could potentially be reduced. Tamsulosin may also increase patient satisfaction by reducing the invasive treatment and decreasing the time to stone passage. This review focuses on the efficacy of tamsulosin based on stone location, after shock wave lithotripsy, compared with other MET drugs and in the acute setting of the ED.

To examine the effects of the α1A -adrenoceptor antagonist, tamsulosin, on spontaneous contractile and electrical activity in the guinea-pig prostate gland. The effects of tamsulosin (0.1 and 0.3 nM) were investigated in adult and ageing male guinea pig prostate glands using conventional tension recording and electrophysiological intracellular microelectrode recording techniques. Tamsulosin reduced spontaneous activity, and had different age-dependent effects on adult and ageing guinea pigs at different concentrations. 0.1 nM tamsulosin caused a significantly greater reduction of spontaneous contractile and electrical activity in ageing guinea pigs in comparison to adult guinea pigs. In contrast, 0.3 nM tamsulosin had a significantly greater reduction of spontaneous contractile and electrical activity in adult guinea pigs in comparison to ageing guinea pigs. This study demonstrates that tamsulosin can modulate spontaneous myogenic stromal contractility and the underlying spontaneous electrical activity; tamsulosin does not block spontaneous activity. This reduction in spontaneous activity suggests that downstream cellular mechanisms underlying smooth muscle tone are being targeted, and these may represent novel therapeutic targets to better treat benign prostatic hyperplasia. © 2014 Wiley Periodicals, Inc.

The aim of this study was to quantify changes and reversibility in pupil dilation and iris dilator muscle region thickness associated with introduction and subsequent discontinuation of tamsulosin in patients naïve to this drug with the aid of an anterior OCT system. The study was carried out on 7 patients (14 eyes) naïve to tamsulosin and with benign prostatic hypertrophy (BHP). Measurements taken by Vistante OCT were done pre- and post-dilation of the following: pupil size, iris dilator muscle region (DMR) thickness, sphincter muscle region (SMR) thickness, and anterior chamber depth. These measurement were taken at Day 0 (tamsulosin naive), Day 30 (after one month of tamsulosin, the treatment period) and day 60 (after one month of no tamsulosin, the discontinuation period). Post-dilation pupil diameter significantly increased during the discontinuation period ( P  = 0.047). Iris DMR thickness measurements post-dilation significantly decreased during treatment ( P  = 0.00044), discontinuation (0.00011), and combined periods ( P  = 0.000050). Anterior chamber depth measurements in post-dilation were significantly decreased during treatment ( P  = 0.0016), discontinuation ( P  = 0.017), and combined periods ( P  = 0.00022). Tamsulosin discontinuation effectively increases dilated pupil size, a measure that has been inversely linked to IFIS incidence pre-operatively. Decreased DMR thickness in this short term likely illustrates changes aside from atrophy, such as vascular changes. Decreased anterior chamber depths suggest aqueous humor production is decreased as well.

To investigate the efficacy of tamsulosin, a selective alpha-1 blocker, in lower urinary tract symptoms (LUTS) patients with metabolic syndrome (MS). This prospective, multicenter clinical trial included men and women (20-75 years old) with LUTS, with or without MS. Patients were categorized as MS+ or MS-, respectively, and all of them were administered tamsulosin 0.2 mg per oral once daily for 24 weeks. Patients were assessed based on the International Prostate Symptom Score, King's Health Questionnaire (KHQ), Overactive Bladder Questionnaire, uroflowmetry with postvoid residuals, and MS factors (blood pressure, waist-to-hip ratio, and serum levels of fasting blood glucose, triglyceride, and high-density lipoprotein cholesterol) at baseline and at 4, 12, and 24 weeks of treatment. Ninety-two patients were enrolled in this study (53/92 were MS- [57.6%]; 39/92 were MS+ [42.4%]). After 24 weeks of tamsulosin treatment, fasting blood glucose (P = .02) and triglyceride (P Tamsulosin was effective in both LUTS patients with and without MS. Furthermore, tamsulosin had beneficial effects on some of the factors associated with MS. Copyright © 2016 Elsevier Inc. All rights reserved.

To assess the additive effect of sildenafil citrate to tamsulosin in the treatment of lower urinary tract symptoms due to benign prostatic hyperplasia (LUTS/BPH) in men with or without erectile dysfunction (ED). In all, 150 men with untreated LUTS/BPH with or without ED were randomised to receive sildenafil 25 mg once daily (OD) or placebo OD (night time) combined with tamsulosin 0.4 mg OD (day time) for 6 months. Changes from pre-treatment scores in International Prostate Symptom Score (IPSS), IPSS-quality of life (QoL) score, maximum urinary flow rate ( Q max ), and the five-item version of the International Index of Erectile Function questionnaire (IIEF-5) were assessed at 3 and 6 months. Safety profiles were assessed by physical examination and monitoring clinical adverse events. Group A comprised of men who received tamsulosin and sildenafil (75 men), whilst those in Group B received tamsulosin and placebo (75). The IPSS was significantly improved in Group A compared to Group B, at -29.3% vs -13.7% ( P  = 0.039) at 3 months and -37% vs -19.6% ( P  = 0.043) at 6 months after treatment. Q max significantly improved in both groups compared with before treatment ( P  tamsulosin improved LUTS, erectile function, and patient QoL more than tamsulosin monotherapy with the merit of a comparable safety profile in patients with LUTS/BPH.

To compare the safety and efficacy of combined therapy using sildenafil and tamsulosin for management of acute urinary retention (AUR) with tamsulosin alone in patients with benign prostate hyperplasia (BPH). 101 patients were enrolled in a randomized placebo-controlled study from June 2009 to April 2012. Patients presenting with an initial episode of spontaneous AUR underwent urethral catheterization and then prospectively randomized to receive tamsulosin 0.4 mg plus sildenafil 50mg in group A and tamsulosin 0.4 mg plus placebo in group B for three days. Urethral catheter was removed three days after medical treatment and patient's ability to void assessed at the day after catheter removal and seven days later. Patients who voided successfully were followed at least for three months. Mean age of patients was 59.64 ± 3.84 years in group A and 60.56 ± 4.12 years in group B (p value = 0.92). Mean prostate volume and mean residual urine were comparable between both groups (p value = 0.74 and 0.42, respectively). Fifteen patients in group A (success rate: 70%) and nineteen patients in group B (success rate: 62.7%) had failed trial without catheter (TWOC) at 7th day following AUR (p value = 0.3). No significant difference was noted between both groups regarding the rate of repeated AUR at one month and three month follow-up period (p = 0.07 and p = 0.45, respectively). It seems that combination therapy by using 5-phosphodiesterase inhibitor and tamsulosin has no significant advantages to improve urinary retention versus tamsulosin alone.

Tamsulosin is recommended for patients receiving a diagnosis of a ureteral stone less than 10 mm who do not require immediate urologic intervention. Because of conflicting results from recent meta-analyses and large randomized controlled trials, the efficacy of tamsulosin is unclear. We perform a systematic review and meta-analysis to investigate the effect of tamsulosin on stone passage in patients receiving a diagnosis of ureteral stone. MEDLINE, EMBASE, and CENTRAL databases were searched without language restriction through November 2015 for studies assessing the efficacy of tamsulosin and using a double-blind, randomized, controlled trial design. Meta-analysis was conducted with a random-effects model and subgroup analyses were conducted to determine sources of heterogeneity. Eight randomized controlled trials (N=1,384) contained sufficient information for inclusion. The pooled risk of stone passage in the tamsulosin arm was 85% versus 66% in the placebo arm, but substantial heterogeneity existed across trials (I 2 =80.2%; Ptamsulosin (risk difference=22%; 95% confidence interval 12% to 33%; number needed to treat=5). The meta-analysis of the small stone subgroup (Tamsulosin significantly improves stone passage in patients with larger stones, whereas the effect of tamsulosin is diminished in those with smaller stones, who are likely to pass their stone regardless of treatment.

We assess the efficacy and safety of tamsulosin compared with placebo as medical expulsive therapy in patients with distal ureteric stones less than or equal to 10 mm in diameter. This was a randomized, double-blind, placebo-controlled, multicenter trial of adult participants with calculus on computed tomography (CT). Patients were allocated to 0.4 mg of tamsulosin or placebo daily for 28 days. The primary outcomes were stone expulsion on CT at 28 days and time to stone expulsion. There were 403 patients randomized, 81.4% were men, and the median age was 46 years. The median stone size was 4.0 mm in the tamsulosin group and 3.7 mm in the placebo group. Of 316 patients who received CT at 28 days, stone passage occurred in 140 of 161 (87.0%) in the tamsulosin group and 127 of 155 (81.9%) with placebo, a difference of 5.0% (95% confidence interval -3.0% to 13.0%). In a prespecified subgroup analysis of large stones (5 to 10 mm), 30 of 36 (83.3%) tamsulosin participants had stone passage compared with 25 of 41 (61.0%) with placebo, a difference of 22.4% (95% confidence interval 3.1% to 41.6%) and number needed to treat of 4.5. There was no difference in urologic interventions, time to self-reported stone passage, pain, or analgesia requirements. Adverse events were generally mild and did not differ between groups. We found no benefit overall of 0.4 mg of tamsulosin daily for patients with distal ureteric calculi less than or equal to 10 mm in terms of spontaneous passage, time to stone passage, pain, or analgesia requirements. In the subgroup with large stones (5 to 10 mm), tamsulosin did increase passage and should be considered. Copyright © 2015 American College of Emergency Physicians. Published by Elsevier Inc.

Full Text Available Abstract Introduction Tamsulosin, a selective α1-adrenergic receptor (α1-AR antagonist, is a widely prescribed first-line agent for benign prostatic hypertrophy (BPH. Its interaction with anesthetic agents has not been described. Case presentation We report the case of 54-year-old Asian man undergoing elective left thyroid lobectomy. The only medication the patient was taking was tamsulosin 0.4 mg for the past year for BPH. He developed persistent hypotension during the maintenance phase of anesthesia while receiving oxygen, nitrous oxide and 1% isoflurane. The hypotension could have been attributable to a possible interaction between inhalational anesthetic and tamsulosin. Conclusion Vigilance for unexpected hypotension is important in surgical patients who are treated with selective α1-AR blockers. If hypotension occurs, vasopressors that act directly on adrenergic receptors could be more effective.

AIM The aim of this small patient study was to investigate tamsulosin concentrations in prostate and plasma samples in order to identify potential differences in the pharmacokinetics (PK) in plasma and prostate contributing to its pharmacodynamic activity profile in patients. METHODS Forty-one patients with benign prostatic hyperplasia (BPH) scheduled for open prostatectomy were given tamsulosin 0.4 mg for 6–21 days in order to reach steady-state PK. Patients were randomized over four groups to allow collection of plasma and tissue samples at different time points after last dose administration. Samples were collected during surgery and assayed for tamsulosin HCl. The free fraction (fu) of tamsulosin was determined by ultracentrifugation of plasma and prostate tissue spiked with 14C-tamsulosin. RESULTS Cmax in plasma at 4.4 h for total tamsulosin was 15.2 ng ml−1 and AUC(0,24 h) was 282 ng ml−1 h, while for prostate Cmax at 11.4 h post-dose was 5.4 ng ml−1 and AUC(0,24 h) was 120 ng ml−1 h. AUC(0,24 h) for total tamsulosin in prostate was 43% of the plasma AUC(0,24 h). fu was 0.4 % for plasma and 59.1% for prostate. Therefore calculated on unbound tamsulosin, a ratio of 63 resulted for prostate vs. plasma Cmax concentrations. CONCLUSIONS These data indicate that in patients with confirmed BPH the amount of tamsulosin freely available in the target tissue (prostate) is much higher than in plasma. PMID:21745239

Full Text Available OBJECTIVE: The aim of this study was to compare the efficacy, safety and tolerability of Dutasteride vs Finasteride in a fixed dose combination, with a uro-selective a-blocker Tamsulosin, in the management of symptomatic BPH associated with LUTS. MATERIALS AND METHODS: 105 males between 40-80 years, clinically diagnosed as Benign prostatic hyperplasia (BPH having a baseline evaluation of their IPSS, UFR, PSA, LFT, KFT, sex health, ultrasound of prostate and PVUV, were randomized to receive a fixed dose combination therapy of Tamsulosin (0.4 mg with Finasteride (5 mg, vs Tamsulosin (0.4 mg with Dutasteride (0.5 mg, daily for six consecutive months. Follow- up at the end of the 2nd, 4th, 8th, 12th and 24th week was done with IPSS, UFR, PSA, ultrasound of Prostate, PVUV and sex health. RESULTS: There were five dropouts, three from the Finasteride arm and two from Dutasteride arm, leaving a total of 100 patients for the final evaluation. Patients in both the groups showed improvement in their symptoms score and urine flow rate from the baseline, but those with the Dutasteride combination not only showed much better improvement in their symptoms score and urine flow, but were also relieved of their obstructive symptoms earlier (10-14 days than seen in the Finasteride group (24-35 days. None of the patients had acute retention of urine (AUR during the trial. The post void urine volume was decreased more in the Dutasteride group, than in patients with Finasteride. Sexual dysfunction incidence was same in both the groups. Approximately 50% reduction in the PSA level was seen in both the groups, while LFT did not show significant difference from the baseline, in either group. Both the drugs were well tolerated, with the patient′s good compliance and with no drop-out due to adverse effects. CONCLUSION : A combination of a-adrenergic blocker and 5-ARI is the best therapeutic option for medical management of BPH as it is safe, effective and well tolerated

To analyze the clinical effect of tamsulosin and Solifenacin in the treatment of benign prostatic hyperplasia in combination with overactive bladder and its safety. Another objective was to investigate the clinical effect and safety of mega dose of tamsulosin in the treatment of benign prostatic hyperplasia in combination with overactive bladder. One hundred and twenty-four patients who were admitted to the Dept. of Urology at Binzhou People's Hospital, , China with confirmed benign prostatic hyperplasia (BPH) with overactive bladder were randomly divided into two groups. Sixty-two patients in the control group were treated with tamsulosin, while sixty-two patients in the observation group were treated with tamsulosin in combination with solifenacin. The treatment of both groups lasted for 12 weeks. The effect and adverse reaction were compared between the two groups. The international prostate symptom score (IPSS), quality of life (QOL), and overactive bladder symptom score (OABSS), Q max , pulmonary vascular resistance (PVR), daytime urination frequency, urgent urination frequency, urge urinary incontinence frequency and night urinary frequency of both groups improved after treatment, and the difference had statistical significance (P0.05). Treating benign prostatic hyperplasia in combination with overactive bladder with tamsulosin in combination with solifenacin is more effective than tamsulosin, without significantly increasing adverse reactions. Thus the therapy is worth clinical promotion.

DETERMINATION OF TAMSULOSIN HYDROCHLORIDE RELEASE PHARMACOKINETICS IN PROSTATE GLAND BY A RADIOTRACER METHOD

Full Text Available Introduction: recently in Ukraine prostate diseases have taken one of the leading places among male urological pathologies. Prostate gland hyperplasia is one of the most common ones. Causes of hyperplasia have not been reliably established so far, however, it has been proved that the poor state of androgen production in men is an integral condition for the development of benign prostatic hyperplasia. One of the urgent tasks of modern pharmaceutical science is to create new high-performance drugs in such dosage forms that provide optimal therapeutic effect with minimal adverse complications. Among a large number of drugs for the treatment of prostate diseases a prominent place is occupied by alpha-adrenoblockers – drugs of the first-line treatments that affect the α1А-adrenergic receptors, reduce or completely eliminate the muscle tone of the prostatic urethra and bladder neck. Tamsulosin hydrochloride is a selective and competitive blocker of postsynaptic α1А-adrenergic receptors. The selectivity of tamsulosin to α1А-adrenergic receptors, which are located in the bladder, is 20 times greater than its ability to interact with α1В-adrenoceptors that are located in vascular smooth muscles. Objective: to study the pharmacokinetics of tamsulosin hydrochloride release into prostate gland after oral and rectal administration by a radioactive-tracer technique. Materials and methods of research: tamsulosin hydrochloride substance and suppositories with this substance labeled by 14С with a specific activity of 3.7× 107Bq/mg. Pharmacokinetic studies of tamsulosin hydrochloride in the prostate were performed after oral and rectal administration. The experiments were carried out on white mature male rats of Wistar line weighing 210 ± 10 g. Pharmacokinetic studies were performed using a radioactive-tracer technique (tracers after oral and rectal administration of tamsulosin.

Benign prostatic hyperplasia (BPH) is a common and progressive disease affecting elderly males, often associated with lower urinary tract symptoms (LUTS). α1-blockers are the mainstay in symptomatic therapy of BPH. Because of their greater uroselectivity and minimal hemodynamic effects, alfuzosin, tamsulosin, and silodosin are generally preferred. The aim of this study was to compare the efficacy and tolerability of alfuzosin, tamsulosin, and silodosin in patients with BPH and LUTS. Ninety subjects with BPH and LUTS were randomized into three groups of thirty in each, to receive alfuzosin sustained release (SR) 10 mg, tamsulosin 0.4 mg, or silodosin 8 mg for 12 weeks. The primary outcome measure was a change in the International Prostate Symptom Score (IPSS), and the secondary outcome measures were changes in individual subjective symptom scores, quality of life score (QLS), and peak flow rate (Qmax) from baseline. The treatment response was monitored at 2, 4, 8, and 12 weeks. IPSS improved by 88.18%, 72.12%, and 82.23% in alfuzosin SR, tamsulosin and silodosin groups (P 75% in all the three groups (P tamsulosin (P = 0.025 and P tamsulosin (three subjects). Alfuzosin, tamsulosin, and silodosin showed similar efficacy in improvement of LUTS secondary to BPH, with good tolerability, acceptability, and minimum hemodynamic adverse effects. Alfuzosin, tamsulosin, and silodosin are comparable in efficacy in symptomatic management of BPH. The occurrence of QTc prolongation in three subjects with tamsulosin in the present study is an unexpected adverse event as there are no reports of QTc prolongation with tamsulosin in any of the previous studies.

To evaluate the relationship between 1-day postoperative intraocular pressure (IOP) after phacoemulsification cataract surgery and tamsulosin use. University of Colorado Health Eye Center, Aurora, Colorado, USA. Retrospective cohort study. Registry data from men who had cataract surgery were used. Patients taking tamsulosin at the time of surgery were included as cases, while patients with no history of tamsulosin use were used as controls. The primary outcome was a 1-day postoperative IOP spike defined as an IOP increase greater than 10 mm Hg compared with baseline or a 1-day postoperative IOP of 30 mm Hg or higher. General estimating equations were used for analysis. The study comprised 584 men (864 eyes). An IOP increase greater than 10 mm Hg or IOP 30 mm Hg or higher after cataract surgery occurred in 12.4% and 9.3%, respectively, of eyes in the tamsulosin group versus 4.4% and 2.1%, respectively, in the control group (all P = .001). After adjusting for significant covariates, patients on tamsulosin were 2.6 times (95% confidence interval [CI], 1.2-5.7; P = .01] and 3.8 (95% CI, 1.3-10.9; P = .01) more likely to have a 1-day postoperative IOP increase greater than 10 mm Hg or a 1-day postoperative IOP of 30 mm Hg or higher. Patients on tamsulosin had an increased risk of a 1-day postoperative IOP spike after cataract surgery, showing the importance of identifying patients on tamsulosin preoperatively to better manage and potentially mitigate IOP spikes.

Benign prostatic hyperplasia (BPH) is the most common cause of lower urinary tract symptoms in elderly men. Selective alfa1-adrenergic antagonists are now first-line drugs in the medical management of BPH. We conducted a single-blind, parallel group, randomized, controlled trial to compare the effectiveness and safety of the new alfa1-blocker silodosin versus the established drug tamsulosin in symptomatic BPH. Ambulatory male BPH patients, aged above 50 years, were recruited on the basis of International Prostate Symptom Score (IPSS). Subjects were randomized in 1:1 ratio to receive either tamsulosin 0.4 mg controlled release or silodosin 8 mg once daily after dinner for 12 weeks. Primary outcome measure was reduction in IPSS. Proportion of subjects who achieved IPSS tamsulosin were analyzed. Final IPSS at 12-week was significantly less than baseline for both groups. However, groups remained comparable in terms of IPSS at all visits. There was a significant impact on sexual function (assessed by IPSS sexual function score) in silodosin arm compared with tamsulosin. Prostate size and uroflowmetry parameters did not change. Both treatments were well-tolerated. Retrograde ejaculation was encountered only with silodosin and postural hypotension only with tamsulosin. Silodosin is comparable to tamsulosin in the treatment of BPH in Indian men. However, retrograde ejaculation may be troublesome for sexually active patients.

To compare the efficacy of combination therapy with an alpha-blocker and an anticholinergic to monotherapy with an alpha blocker on lower urinary tract symptoms (LUTS) following brachytherapy in prostate cancer patients. A total of 124 patients that had been clinically diagnosed with localized prostate cancer and underwent prostate brachytherapy were enrolled in the present study. Patients were randomized and allocated to two groups, including 60 to the combination group (tamsulosin 0.2 mg/day and trospium chloride 20 mg twice daily) and 64 to the monotherapy group (tamsulosin 0.2 mg/day). Treatment began 1 day after brachytherapy and continued for 6 months. LUTS were compared between the two groups using the total International Prostate Symptom Score (IPSS), storage and voiding IPSS subscores, quality of life (QoL) scores, maximum flow rate (Qmax), and postvoid residual (PVR) urine volume at 1, 3, 6, and 12 months after implantation. In all, 111 patients were ultimately analyzed in the study. Compared with pretreatment scores, a significant increase in total IPSS was found at 1, 3, and 6 months in both groups, but no statistically significant differences were observed between the two groups. The combination therapy group showed a greater decrease in the IPSS storage score compared with the monotherapy group at 1, 3, and 6 months (p = 0.031, 0.030 and 0.042, respectively). Patients receiving tamsulosin plus trospium chloride also showed significant improvements in QoL at 1 and 3 months compared with tamsulosin alone (P = 0.039, P = 0.047). Between the two groups, there was no significant difference in IPSS voiding score, Qmax, and PVR from baseline to each point of the study period. Combination therapy with tamsulosin and trospium chloride helped to improve IPSS storage symptoms and Qol scores in prostate brachytherapy patients with LUTS compared with tamsulosin monotherapy.

The aim of this study was to investigate the efficacy and tolerability of switching from 0.2 mg tamsulosin to 0.4 mg tamsulosin oral controlled absorption system (OCAS) over a 12-week period in Taiwanese men with lower urinary tract symptoms (LUTS) associated with benign prostatic hyperplasia (BPH). Taiwanese male patients who were dissatisfied with treatment with 0.2 mg tamsulosin were enrolled in this clinical study and switched to 0.4 mg tamsulosin OCAS. Efficacy was assessed over a 12-week period by an International Prostate Symptom Score (IPSS) questionnaire and analysis of urinary flow by uroflowmetry. A statistically significant improvement was observed in total IPSS scores from baseline (14.94±7.41, moderate) to 12 weeks (7.36±5.77, mild) in 81 patients who were switched from 0.2 to 0.4 mg tamsulosin OCAS ( P tamsulosin OCAS dose was well tolerated, with only mild dizziness (five patients) and headache (two patients) as the most frequent adverse events. No clinically significant reduction was observed in blood pressure or vital signs. Treatment with 0.4 mg tamsulosin OCAS in Taiwanese men with LUTS associated with BPH who were dissatisfied with 0.2 mg tamsulosin significantly improved IPSS scores, urinary flow, and QOL and was well tolerated, suggesting that this should be the recommended dose offered to Taiwanese male patients.

A dutasteride 0.5 mg and tamsulosin hydrochloride 0.4 mg combination (DTC) capsule (Duodart ® ) was reformulated to reduce the capsule size and enhance product stability. Bioequivalence of the reformulated DTC capsule with the commercial formulation was evaluated in 2 single-dose, open-label, randomized, 2-way crossover studies in healthy adult male volunteers. Subjects in a fasted or fed state received a single oral dose of either the reformulated DTC or the commercial formulation followed by a 28-day washout period between treatments. Blood samples were taken predose and up to 72 hours postdose for pharmacokinetic (PK) analysis of dutasteride and tamsulosin serum concentrations. From the serum concentration-vs-time data, a noncompartmental method was used to calculate the maximum observed serum concentration (C max ) and area under the serum concentration-time curve (AUC 0-t ) for dutasteride and tamsulosin, and AUC 0-∞ for tamsulosin. The 90% confidence intervals for the ratios of the C max and AUC 0-t (for dutasteride and tamsulosin) and for AUC 0-∞ (for tamsulosin) were all completely contained within the range of 80% to 125%; therefore, the reformulated DTC capsule is bioequivalent to the commercial formulation under both fed and fasted states. © 2017, The American College of Clinical Pharmacology.

In this work, effect of tamsulosin as antagonist of alpha1A and alpha1B adrenergic receptor and effect of agonists of beta2 adrenergic receptor-salbutamol in patients with increased bronchial reactibility was studied. Parameters of the lung function are determined with Body plethysmography six (6) hours after administration of tamsulosin. Raw and ITGV were registered and specific resistance (SRaw) was calculated as well. Tamsulosin was administered in per os manner as a preparation in the shape of the capsules with a brand name of "Prolosin", produced by Niche Generics Limited, Hitchin, Herts. After six (6) hours of administration of tamsulosin, results gained indicate that blockage of alpha1A and alpha1B-adrenergic receptor (0.8 mg per os) has not changed significantly (p > 0.1) the bronchomotor tonus of tracheobronchial tree in comparison to the check-up that has inhaled salbutamol agonist of adrenergic beta2 receptor (2 inh. x 0.2 mg), (p tamsulosin. This suggests that even after six hours of administration of tamsulosin, and determining of lung function parameters, the activity of alpha1A and alpha1B-adrenergic receptor in the smooth bronchial musculature has not changed in patients with increased bronchial reactibility.

Full Text Available Context: There has been a paradigm shift in the management of ureteral calculi in the last decade with the introduction of new less invasive methods, such as ureterorenoscopy and extracorporeal shock wave lithotripsy (ESWL. Aims: Recent studies have reported excellent results with medical expulsive therapy (MET for distal ureteral calculi, both in terms of stone expulsion and control of ureteral colic pain. Settings and Design: We conducted a comparative study in between watchful waiting and MET with tamsulosin. Materials and Methods: We conducted a comparative study in between watchful waiting (Group I and MET with tamsulosin (Group II in 60 patients, with a follow up of 28 days. Statistical Analysis: Independent ′t′ test and chi-square test. Results: Group II showed a statistically significant advantage in terms of the stone expulsion rate. The mean number of episodes of pain, mean days to stone expulsion and mean amount of analgesic dosage used were statistically significantly lower in Group II (P value is 0.007, 0.01 and 0.007, respectively as compared to Group I. Conclusions: It is concluded that MET should be considered for uncomplicated distal ureteral calculi before ureteroscopy or extracorporeal lithotripsy. Tamsulosin has been found to increase and hasten stone expulsion rates, decrease acute attacks by acting as a spasmolytic, reduces mean days to stone expulsion and decreases analgesic dose usage.

AIMS The main objective of this study was to characterize the population pharmacokinetics of tamsulosin hydrochloride (HCl) in paediatric patients with neuropathic and non-neuropathic bladder. A secondary objective was to compare the pharmacokinetics in paediatric patients and adults. METHODS Tamsulosin HCl plasma concentrations in 1082 plasma samples from 189 paediatric patients (age range 2–16 years) were analyzed with NONMEM, applying a one compartment model with first-order absorption. Based on the principles of allometry, body weight was incorporated in the base model, along with fixed allometric exponents. Covariate analysis was performed by means of a stepwise forward inclusion and backward elimination procedure. Simulations based on the final model were used to compare the pharmacokinetics with those in adults. RESULTS Beside the priori-implemented body weight, only α1-acid glycoprotein had an effect on both apparent clearance and apparent volume of distribution. No other investigated covariates, including gender, age, race, patient population and concomitant therapy with anti-cholinergics, significantly affected the pharmacokinetics of tamsulosin HCl (P tamsulosin HCl in paediatric patients was established and it described the data well. There was no major difference in the pharmacokinetics of tamsulosin HCl between paediatric patients (age range 2–16 years) and adults when the effect of body weight was taken into consideration.

Full Text Available Objective: The rationale of using α1, blockers in the man-agement of benign prostatic hyperplasia (BPH is based upon blocking the adrenergic receptors which regulate urinary outflow The prostate adenoma is predominantly stromal, having 40% of smooth muscle innervated by sym-pathetic adrenergic nerves stimulation of which accounts for 50% of outflow obstruction. Tamsulosin is an uroselective α1a/d blocker, controls both the lower urinary irritative and obstructive symptoms. The present study is a placebo controlled study evaluating the efficacy, safety and advantages of tamsulosin in the management of BPH. Methods: A total number of 72 patients between 40-80 years of age were randomized to two groups. One group (38 patients received tamsulosin (0.4 mg daily and the other group (34 patients received placebo for a period of two months with periodic follow up at 2nd , 4 th and 8 th week with IPSS (International Prostate Symptom Score and uroflowmetry and ultrasonography at 8 th week. Results: Our results show tamsulosin to be very effec-tive in the management of BPH cases, not requiring sur-gery, with few side effects and good patient compliance. The improvement was seen both in IPSS (total, obstruc-tive and irritative and in urodynamic parameters. The differences were consistently superior with tamsulosin as compared to placebo in both the IPSS as well as uroflow-metry measurements. Conclusion: Tamsulosin was found to be a very safe, well tolerated drug showing significant improvement in urinary outflow symptoms, reducing post void urine volume and decreasing IPSS with minimal tolerable adverse events.

Many minimally invasive interventional techniques as well as expectant treatments exist for the management of lower ureteric calculi. This study was conducted to evaluate the efficacy of tamsulosin as an expulsive pharmacologic therapy for the treatment of distal ureteral stone. Methods: This randomized control trial included 100 patients over 18 years of age with stone Size = 8mm in distal 1/3 of ureter. Patients were randomly assigned into two groups (A and B). Group A Patients were given Capsule Tamsulosin 0.4 mg, 1 daily up to 4 weeks while group B patients were given placebo, 1 Capsule daily up to 4 weeks. The primary endpoint was expulsion rate. A written informed consent was taken from all the patients. Expulsion time, need for analgesics, need for hospitalization and drug side effects were secondary endpoints. Results: A total of 49 patients in group A and 48 patients in group B reported back, therefore 97 out of 100 patients were evaluated. Mean age of the patients was 36.34 years (range 18-57 years). Mean stone size was 5.78 mm (range 4-8 mm) in greatest dimension. A stone expulsion rate of 85.71% (42 patients) was noted in group A and 54.20% (26 patients) in group B. Group A revealed a statistically significant advantage in term of stone expulsion rate (p=0.032). Considering expulsion time in days group A showed statistically significant advantage (p=0.015). Regarding age, sex, stone size and stone lateralization (right/left), there was no significant difference between the group A and B. No drug side effects were noted in both the groups. Conclusion: By using tamsulosin a higher stone expulsion rates can be achieved in a shorter time. More randomized control trials are required to establish tamsulosin as a standard medical expulsive treatment for small distal ureteric calculus. (author)

To evaluate the efficacy and safety of tamsulosin dose increase to 0.4 mg daily in Asian patients with lower urinary tract symptoms secondary to benign prostatic hyperplasia refractory to tamsulosin 0.2 mg treatment. We carried out a 12-week, single-center, randomized, placebo-controlled trial in 220 patients. Patients treated with 0.2 mg tamsulosin daily without other lower urinary tract symptoms secondary to benign prostatic hyperplasia medication for more than 3 months and refractory to this treatment were enrolled. We defined "refractory" as an International Prostate Symptom Score of 13 or greater and a maximum flow rate of 15 or under despite medication. Patients with a surgical history related to lower urinary tract symptoms secondary to benign prostatic hyperplasia or a postvoid residual of 150 mL or greater were excluded. Eligible patients were randomly assigned to the 0.4 mg group (two tablets of 0.2 mg tamsulosin once daily) or the 0.2 mg group (one tablet of 0.2 mg tamsulosin and one tablet of placebo once daily). International Prostate Symptom Score, maximum flow rate, blood pressure, heart rate, and adverse events were compared between the two groups at 4 weeks and 12 weeks. A total of 220 patients were enrolled and analyzed. There were no differences in baseline characteristics between the two groups. After 12 weeks of medication, the International Prostate Symptom Score was not different between the two groups. However, the improvement in maximum flow rate was greater in the 0.4 mg group than the 0.2 mg group (3.0 ± 0.48 mL/s vs -0.25 ± 0.30 mL/s, P Tamsulosin 0.4 mg appears to be a safe treatment regimen for treating lower urinary tract symptoms secondary to benign prostatic hyperplasia in Asian patients who do not respond to 0.2 mg treatment. Increasing the dose of tamsulosin results in a significant improvement in maximum flow rate without any increase in cardiovascular complications. © 2014 The

The objective of the study is to determine if tamsulosin initiated in the emergency department (ED) decreases the time to ureteral stone passage at 1 week or time to pain resolution, compared to placebo. We performed a prospective, randomized, double-blinded, placebo-controlled trial of tamsulosin vs placebo in ED patients with ureterolithiasis on computed tomography. Patients were identified and enrolled between April 2007 and February 2009 and were randomized to either 0.4 mg of tamsulosin or placebo for 1 week. We contacted participants using a telephone survey on post-ED visit days 1, 2, 3, and 7. The primary outcome was time to stone passage, with secondary outcomes being maximum pain score and amount of pain medication required. Of the 127 patients enrolled during this study, 15 were lost to follow-up, and 12 required surgical interventions before the 7-day mark, leaving 100 patients for analysis. Of the 100 patients, 53 received tamsulosin and 47 received placebo. There was no difference between groups in percentage of male, mean age, initial serum creatinine, average stone size, stone location, and history of prior stone. The probability that the patient did not pass a stone at 7 days was not different between tamsulosin and placebo, 62.1% (95% confidence interval, 49.1%-75.1%) vs 54.4% (95% confidence interval, 40.3%-68.6%; P = .58). There was no significant difference in the high pain score (P = .12) or hydrocodone/acetaminophen intake (P = .76) between treatment groups at any of the time points. This study reveals no difference in the proportion of stone passage or high pain score and pain medication utilization at 7 days between tamsulosin and placebo. Copyright © 2015 Elsevier Inc.

Symptom assessment with the American Urological Association Symptom Score (AUASS and urodynamic evaluation was performed initially and after three months of treatment. Patient satisfaction was evaluated and severe adverse drug effects recorded. Statistical analysis was carried out using the Student’s t-test and Mann–Whitney U test.Results: Although AUASS improved in both groups, the rate of improvement was larger in the tamsulosin group. Urodynamic parameters improved but did not normalize in both groups. Adverse side effects from medication in the prazosin group were more common than in the tamsulosin group. Most of the patients in the tamsulosin group (80% were satisfied with their treatment compared with those in the prazosin group (45%.Conclusion: Tamsulosin and prazosin are both effective in palliating symptoms of women with voiding dysfunction and improving their urodynamic parameters. Tamsulosin may be the preferred drug to prescribe because of its more amenable side effect profile and greater patient satisfaction.Keywords: tamsulosin, prazosin, voiding dysfunction

  The purpose of this study was to assess the incidence of intraoperative floppy iris syndrome (IFIS) and the morphology of the corneal endothelium after cataract extraction in Caucasian male patients exposed to the α-1a adrenergic receptor antagonist tamsulosin.   In a clinical prospective study, 23 male patients (23 eyes) treated with tamsulosin due to benign prostatic hyperplasia and 25 male patients (25 eyes) with no tamsulosin treatment had cataract surgery. The divide-and-conquer technique was used with the Infinity OZil(®) machine. A combination of Healon and Healon5 was used in all patients, but the use of additional Vision Blue, iris retractors or intracameral phenylephrine in the tamsulosin group was at the discretion of the surgeon. The endothelial cell density, variation in endothelial cell size (CV), percentage of hexagonal cells and central corneal thickness (CCT) were recorded at baseline and at 3 months postoperatively.   In the tamsulosin-treated group, 19 of 23 eyes (83%) developed IFIS, compared with no IFIS in the control group. Compared with the control group, the tamsulosin group showed significantly less dilatation at the start of the operation, significant miosis during surgery and significantly greater corneal endothelial cell loss 3 months postoperatively (12% versus 3%; ptamsulosin-treated male patients. Patients on tamsulosin showed less preoperative dilatation, significant miosis during surgery, and had significantly greater postoperative endothelial cell loss compared with nontreated patients despite recommended precautions. © 2013 Acta Ophthalmologica Scandinavica Foundation.

Clinicians use tamsulosin, an α1-adrenoceptor antagonist, to manage symptomatic benign prostatic hyperplasia (BPH). Because α1-adrenoceptors are also present in the brain, the potential exists for adverse effects on cognitive functions. We explored the association between tamsulosin use and dementia risk. We used Medicare data (2006-2012) to conduct a cohort study among patients aged ≥65 years and diagnosed with BPH. Men taking tamsulosin (n = 253 136) were matched at a 1:1 ratio using propensity-scores to each of 6 comparison cohorts: patients who used no BPH-medication (n = 180 926), and patients who used the following alternative-BPH-medications: doxazosin (n = 28 581), terazosin (n = 23 858), alfuzosin (n = 17 934), dutasteride (n = 34 027), and finasteride (n = 38 767). Assessment began following the first fill of BPH-medication to identify incident dementia by ICD-9 diagnosis codes. We estimated hazard ratios (HR) and 95% confidence intervals (CI) for dementia using Cox proportional hazard regression for each of the 6 propensity-score-matched cohort-pairs. The median follow-up period for all cohorts was 19.8 months. After propensity-score matching, the tamsulosin cohort had an incidence of dementia of 31.3/1000 person-years compared with only 25.9/1000 person-years in the no-BPH-medication cohort. The risk of dementia was significantly higher in the tamsulosin cohort, when compared with the no-BPH-medication cohort (HR [95% CI]: 1.17 [1.14, 1.21]) and each of the alternative-BPH-medication cohorts: doxazosin (1.20 [1.12, 1.28]), terazosin (1.11 [1.04, 1.19]), alfuzosin (1.12 [1.03, 1.22]), dutasteride (1.26 [1.19, 1.34]), and finasteride (1.13 [1.07, 1.19]). The significance of these findings persisted in sensitivity analyses. Tamsulosin may increase the risk of dementia in older men with BPH. Copyright © 2018 John Wiley & Sons, Ltd.

To evaluate the in vitro effect of tamsulosin and nifedipine on the contractility of pregnant rat ureters and to perform quantitative analysis of the pharmacological effects. Medical expulsive therapy (MET) is commonly used to treat urolithiasis. However, this treatment is seldom used in pregnant women since no studies support this practice. This was an in vitro study on animal tissue derived from pregnant Sprague-Dawley rats. A total of 124 ureteral segments were mounted in an organ bath system and contractile response to methacholine (MCh) was assessed. Tamsulosin or nifedipine were added at cumulative concentrations (0.001-1 μM). The area under the curve (AUC) from isometric tension measurements was calculated. The effect of pharmacological agents and the respective controls were assessed by calculating the AUC for each 5-min interval. Statistical analyses were performed using the Mann-Whitney-Wilcoxon nonparametric test. Both drugs displayed statistically significant inhibitory activity at concentrations of 0.1 and 1 μM for tamsulosin and 1 μM for nifedipine when calculated as the AUC as compared to DMSO controls. Tamsulosin and nifedipine directly inhibit MCh-induced contractility of pregnant rat ureters. Further work is needed to determine the clinical efficacy of these medications for MET in pregnancy.

A highly sensitive method for quantitation of tamsulosin in human plasma using 1-(2,6-dimethyl-3-hydroxylphenoxy)-2-(3,4-methoxyphenylethylamino)-propane hydrochloride as the internal standard (I.S.) was established using liquid chromatography-electrospray ionization-mass spectrometry (LC-ESI-MS). After alkalization with saturated sodium bicarbonate, plasma were extracted by ethyl acetate and separated by HPLC on a C18 reversed-phase column using a mobile phase of methanol-water-acetic acid-triethylamine (620:380:1.5:1.5, v/v). Analytes were quantitated using positive electrospray ionization in a quadrupole spectrometer. LC-ESI-MS was performed in the selected ion monitoring (SIM) mode using target ions at m/z 228 for tamsulosin and m/z 222 for the I.S. Calibration curves, which were linear over the range 0.2-30 ng/ml, were analyzed contemporaneously with each batch of samples, along with low (0.5 ng/ml), medium (3 ng/ml) and high (30 ng/ml) quality control samples. The intra- and inter-assay variability ranged from 2.14 to 8.87% for the low, medium and high quality control samples. The extraction recovery of tamsulosin from plasma was in the range of 84.2-94.5%. The method has been used successfully to study tamsulosin pharmacokinetics in adult humans.

The primary aim of this study was to evaluate whether there was clinically significant pharmacokinetic (PK) interaction between finasteride and tamsulosin in healthy Chinese male subjects. This was an open-label, randomized, 3-period, crossover study. Subjects received single and multiple doses of 5 mg finasteride alone, single and multiple doses of 0.2 mg tamsulosin hydrochloride sustained-release capsule alone, and single and multiple doses of 5 mg finasteride with 0.2 mg tamsulosin hydrochloride, in an order determined by a computerized randomization schedule. Blood samples were collected up to 48 hours after dosing on study day 1 and up to 24 hours after dosing on study day 9 for determination of plasma concentrations with a validated LC-MS/MS method. Pharmacokinetic parameters were estimated via noncompartmental methods. Tolerability was evaluated by monitoring adverse events, laboratory assays, vital signs, and 12-lead ECG. Fifteen subjects were enrolled, and 14 completed the study. The geometric mean ratios (GMRs) (90% CIs) of AUC(τ,ss) and C(max,ss) values of finasteride at steady state between coadministration of finasteride and tamsulosin hydrochloride and finasteride alone were 1.14 (1.05-1.23) and 1.06 (0.99-1.14), respectively. The GMRs (90% CIs) for AUC(0-t) and C(max) values of finasteride for a single dose of coadministration of finasteride and tamsulosin hydrochloride and finasteride alone were 1.02 (0.94-1.11) and 1.06 (1.01-1.11), respectively. The GMRs (90% CIs) for AUC(τ,ss) and C(max,ss) values of tamsulosin at steady-state for coadministration of finasteride and tamsulosin hydrochloride and tamsulosin hydrochloride alone were 1.18 (1.05-1.33) and 1.23 (1.06-1.43), respectively. The GMRs (90% CIs) for AUC(0-t) and C(max) values of tamsulosin for a single dose of coadministration of finasteride and tamsulosin hydrochloride and tamsulosin hydrochloride alone were 1.04 (0.97-1.10) and 1.04 (0.98-1.11), respectively.

To evaluate the association of prostate biopsy with voiding impairment and to investigate whether tamsulosin treatment given before prostate biopsy could improve voiding dysfunction after the procedure. The study included 88 consecutive patients who underwent transrectal ultrasound-guided prostate biopsy without prior BPH medication and were prospectively randomized. Of these 88 patients, 44 patients underwent prostate biopsy only without tamsulosin treatment and served as the control group. The remaining 44 patients were treated with tamsulosin (0.2 mg daily) beginning the day before the biopsy procedure for 7 days. The International Prostate Symptom Score (IPSS) was recorded in all patients before the procedure and on postbiopsy day 7. Maximal flow rate (Q(max)) and postvoid residual urine volume were recorded in all patients before the procedure and on postbiopsy days 1 and 7. No difference was found in baseline characteristics between the two groups. The IPSS (total, storage, and voiding symptom) was not significantly changed after biopsy in both groups. In the control group, the postvoid residual urine volume was increased on postbiopsy days 1 (P tamsulosin group, Q(max) was significantly increased on postbiopsy days 1 and 7 (P tamsulosin group, but it developed in two patients (4.5%) of the control group. The results of our study show that prostate biopsy leads to objective voiding impairment. Therefore, the use of alpha-1 blocker tamsulosin before biopsy in patients without prior BPH medication may decrease this morbidity.

Male temporary contraception is occasionally required in some animals. Alpha1-adrenoceptor antagonist (tamsulosin) can cause ejaculation disorder. Two sets of Latin square were applied to six male goats to received either normal saline, dimethylsulphoxide or tamsulosin (179.8 nmol kg(-1) ) at 1-week interval. Semen collection and libido scoring were undertaken at 3, 6 and 24 h post-injection. For ejaculated semen, its quality was evaluated. Physiological measurements including body temperature, respiration and heart rates were measured before injection and at 30 min before semen collection. The results showed that libido score and physiological changes were not affected by treatments and time periods. Anejaculation was observed in 11 (91.7%), 5 (41.7%) and 1 (8.3%) males at 3, 6 and 24 h post-tamsulosin injection respectively. The incidence returned to normal when compared with control groups at 24 h. The percentages of motile and live spermatozoa at 6 h post-tamsulosin injection were significantly lower (P tamsulosin had temporary effects on ejaculation and semen quality without reducing sex desire and physiological functions in male goats. © 2014 Blackwell Verlag GmbH.

Administration of nifedipine or tamsulosin has been suggested to augment stone expulsion rates. We aimed to compare the stone expulsion rates and adverse effects associated with the use of nifedipine or tamsulosin as medical expulsive therapy (MET) for the management of lower ureteral stones (LUS) without extracorporeal shock wave lithotripsy (ESWL) via a literature review and meta-analysis. Relevant randomized controlled trials (RCTs) were identified from the Medline, EMBASE, Cochrane CENTRAL, and Google Scholar databases. Finally, a total of 7 RCTs with 3897 patients were included. Our meta-analysis showed that tamsulosin could significantly increase the stone expulsion rate relative to nifedipine in patients with LUS (random-effects model; risk ratio [RR] = 0.81; 95% confidence interval [CI] = 0.75–0.88; P tamsulosin was more effective than nifedipine in patients with LUS, as evidenced by the higher stone expulsion rate. Tamsulosin treatment should therefore be considered for patients with LUS. PMID:24919112

To properly use the Ureteric Symptom Score Questionnaire (USSQ) to evaluate, in a randomized control study, the effect of tamsulosin, solifenacin, and their combination in improving symptoms and quality of life in patients with indwelling ureteral stents. After institutional review board approval, 260 patients with a ureteral stent were randomly assigned to receive tamsulosin 0.4 mg, solifenacin 5 mg, or placebo and further randomized to receive their combination. The validated USSQ was completed 1 and 4 weeks after stent insertion and 4 weeks after stent removal. Kruskal-Wallis test, chi-squared test (or Fisher's exact test), one-way analysis of variance, and T-test (or Wilcoxon rank-sum test if not normal data) were used for statistical analysis. The results were considered significant at p tamsulosin or solifenacin expressed significantly lower urinary (p tamsulosin and solifenacin alone or in combination, improves stent-related symptoms and has a positive impact on quality of life.

To evaluate the efficacy of tamsulosin therapy in reducing ureteral double-J stent morbidity by evaluating USSQ, IPSS, QOL and VAS (primary objective) and to evaluate the morbidity and or complication(s) associated with indwelling double-J ureteral stent(s) and to evaluate the safety of tamsulosin therapy for "morbidity associated with double-J stents" by evaluating its tolerability, side effects and adverse events if any (secondary objective) as per protocol. After institutional review board approval, 60 consecutive patients with a double-J ureteral stent inserted after percutaneous nephrolithotomy or ureteroscopic stone treatment were randomly assigned to receive tamsulosin 0.4 mg, or a placebo for 4 weeks. The validated USSQ, VAS and IPSS were completed before stent insertion, at 3 days and 4 weeks after stent insertion and at 2 weeks after stent removal. Data were statistically analyzed for efficacy and tolerability of one drug over the other using Wilcoxon signed-rank test, Mann-Whitney test and Student's t test. Patients receiving tamsulosin compared with the placebo showed significant decrease in urinary index score, pain index score, work performance score, VAS score at loin area, VAS score at flank, VAS score at suprapubic area, average VAS score, need for antibiotics, number of hospital visits (P tamsulosin but, however, the decrease was not significant. No patients discontinued medication because of side effects. We conclude that ureteral stenting using double-J stents with concomitant tamsulosin therapy was generally well tolerated, safe, effective and significantly beneficial in reducing stent morbidity in the majority of our patients. We advocate the routine use of concomitant tamsulosin therapy in eligible patients undergoing ureteral stenting in order to minimize stent morbidity.

Full Text Available Purpose Chronic pelvic pain syndrome (CPPS is treated by use of various protocols. We compared tamsulosin monotherapy with tamsulosin in combination with antibiotics or anti-inflammatory agents and evaluated the efficacy of these treatments in patients with CPPS. Methods Patients (n=107 who were younger than 55 years and diagnosed with CPPS were randomly assigned to treatment with tamsulosin at 0.2 mg (group A, tamsulosin at 0.2 mg plus anti-inflammatory drugs (group B or tamsulosin at 0.2 mg plus antibiotics (group C daily. We applied the National Institutes of Health-Chronic Prostatitis Symptom Index (NIH-CPSI and the International Prostate Symptom Score (IPSS to evaluate 100 patients who were treated for 12 weeks (7 withdrew. Scores of the three groups were compared by analysis of variance and we also evaluated subscores, which included pain, voiding and quality of life (QoL. Results All three groups showed statistically significant decreases in NIH-CPSI score, IPSS and subscore scores (P<0.05. There were no statistically significant differences between the groups except for the QoL domain of the IPSS (group A vs. C; P<0.01. Conclusions Tamsulosin monotherapy for 12 weeks was effective for treating patients with CPPS, compared with combination therapy with antibiotics or anti-inflammatory drugs.

To compare the efficacy and safety of silodosin and tamsulosin in patients with lower urinary tract symptoms (LUTS) associated with benign prostatic hyperplasia (BPH) by a randomized crossover method. BPH patients with the complaint of LUTS were included in this study, and were randomly divided into two groups: a silodosin-preceding group (4 weeks of twice-daily administration of silodosin at 4 mg, followed by 4 weeks of once-daily administration of tamsulosin at 0.2 mg) or a tamsulosin-preceding group (4 weeks' administration of tamsulosin, followed by 4 weeks' administration of silodosin). No drug withdrawal period was provided when switching the drug. In the first treatment period, both drugs significantly improved the International Prostate Symptom Score total score, but the improvement by silodosin was significantly superior to that by tamsulosin. After crossover treatment, significant improvement was observed only with silodosin treatment. Moreover, intergroup comparison of changes revealed that silodosin showed significant improvement of straining and nocturia with first and crossover treatments, respectively, compared with tamsulosin. Silodosin also significantly improved quality of life (QOL) score in both treatment periods, while tamsulosin significantly improved QOL score only in the first treatment period. The most frequent adverse drug reaction was ejaculatory disorder with silodosin; however, the incidence of dizziness with silodosin was similar to that with tamsulosin. In BPH/LUTS patients, silodosin exhibits excellent efficacy in improving subjective symptoms in both initial and crossover treatment, and it appears to improve the QOL of patients. © 2010 The Japanese Urological Association.

To assess the effectiveness and safety of tamsulosin combined with androgen deprivation therapy (ADT) for lower urinary tract symptoms (LUTS) in advanced prostate cancer (PC) patients. Ninety PC patients with moderate-to-severe LUTS randomized into two groups of 45 each. One group received ADT (group 1), and the other received ADT plus tamsulosin (group 2) for 24 weeks. The outcome measures were changes in the International Prostate Symptom Score (IPSS), IPSS obstructive and irritative subscores, quality of life (QoL), maximum urinary flow rate (Q max ), post-voiding residual (PVR) and prostate-specific antigen (PSA) from baseline. The treatment response was monitored at 8, 16 and 24 weeks. Both ADT monotherapy and ADT plus tamsulosin significantly improved IPSS,QoL score, Q max and PVR at the end of the treatment period. ADT plus tamsulosin had a greater impact on total IPSS, IPSS obstructive subscore, QoL and PVR at week 8 and week 16 than ADT monotherapy. Tamsulosin group showed greater improvement in Q max than ADT group. Significant improvements of IPSS, IPSS obstructive subscore and QoL were achieved at early treatment stage (week 8) in group 2, whereas similar improvements were achieved at week 16 in group 1. There were no significant differences in IPSS, IPSS subscores, QoL and PVR between the two groups at week 24. Additional administration of tamsulosin showed significantly greater and sooner relief in LUTS than ADT monotherapy, with good acceptability. It is feasible that ADT is used alone after 16-24 weeks of combination therapy.

Aims Tamsulosin is an α1-adrenoceptor antagonist for the treatment of symptomatic benign prostatic hyperplasia with a tolerability similar to that of placebo in short-term, placebo-controlled studies with limited patient numbers. The present study was designed to test the safety of tamsulosin treatment in a large cohort of men during a prolonged period of time, particularly with regard to comedications. Methods A multicentre, open-label phase IIIb study with 1784 patients receiving 0.4 mg o.d. tamsulosin for 6 months was performed according to good clinical practice guidelines. The analysis was performed on an intention-to-treat basis and powered to detect adverse events (AE) occurring in 0.15% of patients with 95% confidence. Results During a total drug exposure time of 811 patient years, 386 AE were recorded in 253 patients (14.2%; 95% confidence intervals [CI] 12.0–15.2%). Twenty-nine patients suffered 44 serious AE including five fatal events (CI 0.12–0.73%) due to myocardial infarction (n = 3) and to pneumonia and a car accident (one each), but all deaths were judged to be unlikely to be related to study medication. The frequency of AE in patients without any comedication (n = 1095) was 13.0% (CI 11.3–14.9%). In a logistic regression analysis β-adrenoceptor blockers, converting enzyme inhibitors, antidiabetics and diuretics did not significantly affect the odds ratio for having AE. However, concomitant α-adrenoceptor antagonists (a protocol violation) and treatment with verapamil (which also has α-adrenoceptor antagonist activity) significantly enhanced the odds ratio for having AE to 3.87 (CI 1.52–9.85) and 3.17 (CI 1.52–6.58), respectively. Minor increases in the odds ratio, which did not reach statistical significance, were also observed for Ca2+ antagonists other than verapamil and for nitrates. Conclusions We conclude that tamsulosin has a good safety profile relative to AE rates in the placebo arms of previous studies on tamsulosin even in

To evaluate the efficacy of tamsulosin for promoting ureteric stone expulsion in children, based on the confirmed efficacy of tamsulosin as a medical expulsive therapy in adults. From February 2010 to July 2013, 67 children presenting with a distal ureteric stone of <1 cm as assessed on unenhanced computed tomography were included in the study. The patients were randomised into two groups, with group 1 (33 patients) receiving tamsulosin 0.4 mg and ibuprofen, and group 2 (34) receiving ibuprofen only. They were followed up for 4 weeks. Endoscopic intervention was indicated for patients with uncontrolled pain, recurrent urinary tract infection, hypersensitivity to tamsulosin and failure of stone passage after 4 weeks of conservative treatment. Sixty-three patients completed the study. There were no statistically significant differences between the groups in patient age, body weight and stone size, the mean (SD) of which was 6.52 (1.8) mm in group 1 vs. 6.47 (1.79) mm in group 2 (P = 0.9). The mean (SD) time to stone expulsion in group 1 was 7.7 (1.9) days, vs. 18 (1.73) days in group 2 (P < 0.001). The analgesic requirement (mean number of ketorolac injections) in group 1 was significantly less than in group 2, at 0.55 (0.8) vs. 1.8 (1.6) (P < 0.001). The stone-free rate was 87% in group 1 and 63% in group 2 (P = 0.025). Tamsulosin used as a medical expulsive therapy for children with ureteric stones is safe and effective, as it facilitates spontaneous expulsion of the stone.

The objective of this study was to compare the relative efficacy of tamsulosin and tadalafil as medical expulsive therapy for distal ureteric stones. This was a prospective study performed between December 2014 and February 2016. A total of 123 adult patients (>18 years of age) presenting with distal ureteric stones sized 6-10 mm were randomized to treatment with tamsulosin 0.4 mg once daily (Group A) or tadalafil10 mg once daily (Group B). Therapy was given for a maximum of 4 weeks. The stone expulsion rate was the primary endpoint. Time to stone expulsion, number of colic episodes, analgesic use, number of hospital visits for pain, endoscopic treatment, and adverse effects of the drugs were noted. Statistical analyses were done using Fisher's exact test and Chi-square test. A total of 61 patients were included in tamsulosin group and 62 patients in tadalafil group. A statistically insignificant difference was found for stone clearance rate between both groups as a whole (Group A-73.77%, Group B-69.35%, P = 0.690) as well as when we considered both subgroups (A1-78.05%, B1-75.0%, P = 0.802; A2-65.0%, B2-55.6%, P = 0.741). All the primary and secondary outcome measures were more in favour of stones ≤8 mm size than stones >8 mm size. No statistical difference was found for adverse drug effects except for retrograde ejaculation, which was significantly high in tamsulosin group ( P tamsulosin is more effective for stone clearance than tadalafil, but this difference was not significant ( P = 0.690).

To compare the effectiveness of tamsulosin and solifenacin in relieving ureteral stents related symptoms. A randomized controlled trial was conducted between January 2013 and July 2014. Inclusion criteria were patients aged 20-50 years who underwent temporary unilateral ureteral stent for drainage of calcular upper tract obstruction or after ureteroscopic lithotripsy. Patients with history of lower urinary tract symptoms before stent placement, stents that were fixed after open or laparoscopic procedures, and those who developed complications related to the primary procedure were not included. Eligible patients were randomly assigned to 1 of 3 groups using computer-generated random tables. Patients in group 1 received placebo, patients in group 2 received tamsulosin 0.4 mg once daily, and those in group 3 received solifenacin 5 mg once daily. Ureteral Stent Symptom Questionnaire (USSQ) was answered by all patients 1-2 weeks after stent placement. The primary outcome was the comparison of total score of USSQ between all groups. The study included 131 patients. All baseline characteristics (age, sex, side, indication, length, and duration of stent) were comparable for all groups. Total USSQ score was 61 in solifenacin group, 76 in tamsulosin group, and 83 in control group (P tamsulosin group (P tamsulosin alone or solifenacin alone in patients with ureteral stents can improve the quality of life by decreasing ureteral stent-related symptoms. Solifenacin was better than tamsulosin. CLINICALTRIAL. NCT01880619.

To examine the impact of tamsulosin on the rate of acute urinary retention following early catheter removal after robot-assisted laparoscopic radical prostatectomy. A total of 236 patients who underwent robot-assisted laparoscopic radical prostatectomy for prostate cancer carried out by a single surgeon were enrolled in this randomized study. Patients were randomly divided into two groups: treatment with tamsulosin (0.4 mg) from 1 day before to 14 days after surgery (tamsulosin group), or no tamsulosin treatment (control group). The urethral catheter was removed on the fifth postoperative day. The primary end-point was the acute urinary retention rate. Changes in each domain of the International Continence Society male short-form questionnaire and uroflowmetry parameters were secondary end-points. The primary end-point was assessed in 218 patients (92.4%; n = 109 in each group). It was not assessed in 18 patients because of cystographic leak from the vesicourethral anastomosis. The acute urinary retention rate was lower in the tamsulosin group (7.3%) than in the control group (17.4%, P = 0.018). Multivariate logistic regression analysis identified tamsulosin treatment and the operative experience of the surgeon as independent risk factors for acute urinary retention. Tamsulosin-treated patients had a 0.30-fold lower risk of developing acute urinary retention compared with control patients (95% confidence interval 0.12-0.76; P = 0.011). None of the International Continence Society male questionnaire domain scores showed significant changes between the groups. Perioperative treatment with tamsulosin in patients undergoing robot-assisted laparoscopic radical prostatectomy reduces the rate of acute urinary retention after early catheter removal, without aggravating urinary incontinence. © 2013 The Japanese Urological Association.

Ureteral stent discomfort is a significant postoperative problem for many patients. Despite the use of narcotics and α-blockers patients often experience bothersome lower urinary tract symptoms and pain, which impair daily activities. We compared combination therapy with an α-blocker and an anticholinergic to monotherapy with an α-blocker. A double-blind, randomized, controlled trial was performed from December 2012 to April 2014. A total of 80 patients were randomized, including 44 to the combination group (tamsulosin 0.4 mg and tolterodine early release 4 mg) and 36 to the monotherapy group (tamsulosin 0.4 mg and placebo). Patients with preexisting ureteral stent placement or current anticholinergic therapy were excluded from study. Patients completed USSQ (Urinary Stent Symptom Questionnaire) before stent placement on the day of surgery, the day after stent placement, the morning of stent removal and the day after stent removal. The questionnaire included questions regarding urinary symptoms, general health, body pain, and work and sexual history. A total of 80 patients (40 males and 40 females) were studied. Mean age was 51.5 vs 51.3 years (p = 0.95) and mean body mass index was 33.6 vs 31.9 kg/m(2) (p = 0.44) in monotherapy group 1 vs combination therapy group 2. Between the 2 groups there was no significant difference in urinary symptoms, body pain and activities of daily living from baseline to just before stent removal (p = 0.95, 0.40 and 0.95, respectively). Although there was no difference between the groups, both showed improvement in urinary symptoms from the time of initial stent insertion to just prior to stent removal (difference -0.50 for combination therapy and -0.40 for monotherapy). The mean stent indwelling time of 9.6 and 8.7 days in the combination and monotherapy groups, respectively, did not differ (p = 0.67). On ANOVA it had no significant impact on results (p = 0.64).

• To investigate the influence of baseline variables on the 4-year incidence of acute urinary retention (AUR), benign prostatic hyperplasia (BPH)-related surgery and overall clinical progression in men treated with tamsulosin, dutasteride, or a combination of both. • The 4-year Combination of Avodart® and Tamsulosin (CombAT) study was a multicenter, randomized, double-blind, parallel-group study of clinical outcomes in men aged ≥ 50 years with symptomatic (International Prostate Symptom Score [IPSS]≥ 12) BPH, with prostate-specific antigen (PSA) levels of ≥ 1.5 ng/mL and ≤ 10 ng/mL, and a prostate volume (PV) of ≥ 30 mL. • Eligible patients received tamsulosin 0.4 mg, dutasteride 0.5 mg, or a combination of both. • The primary endpoint was time to first AUR or BPH-related surgery. Secondary endpoints included clinical progression of BPH and symptoms. Posthoc analyses of the influence of baseline variables (including age, IPSS health-related quality of life [HRQL], PV, PSA, IPSS, peak urinary flow rate [Q(max) ] and body-mass index [BMI]) on the incidence of AUR or BPH-related surgery, clinical progression of BPH, and symptoms were performed. • There were 4844 men in the intent-to-treat population. Overall baseline characteristics were similar across all patient groups. • Regardless of baseline subgroup, the incidence of AUR or BPH-related surgery was higher in men treated with tamsulosin than in those treated with dutasteride or combined therapy. • Combined therapy was statistically better than tamsulosin in reducing the risk of AUR or BPH-related surgery in subgroups of baseline PV > 42.0 mL, in all subgroups of baseline PSA level, and all other baseline subgroups (P ≤ 0.001). • Across treatment groups, the incidence of clinical progression was highest in men with a baseline IPSS of BPH-related surgery and greater reductions in the RR of clinical progression and symptom deterioration on combined therapy or dutasteride monotherapy than

Recent large high-quality trials have questioned the clinical effectiveness of medical expulsive therapy using tamsulosin for ureteral stones. To evaluate the efficacy and safety of tamsulosin for distal ureteral stones compared with placebo. We conducted a double-blind, placebo-controlled study of 3296 patients with distal ureteral stones, across 30 centers, to evaluate the efficacy and safety of tamsulosin. Participants were randomly assigned (1:1) into tamsulosin (0.4mg) or placebo groups for 4 wk. The primary end point of analysis was the overall stone expulsion rate, defined as stone expulsion, confirmed by negative findings on computed tomography, over a 28-d surveillance period. Secondary end points included time to stone expulsion, use of analgesics, and incidence of adverse events. Among 3450 patients randomized between September 1, 2011, and August 31, 2013, 3296 (96%) were included in the primary analysis. Tamsulosin benefits from a higher stone expulsion rate than the placebo (86% vs 79%; ptamsulosin for the treatment of large distal ureteral stones (>5mm). Considering the secondary end points, tamsulosin-treated patients reported a shorter time to expulsion (ptamsulosin use benefits distal ureteral stones in facilitating stone passage and relieving renal colic. Subgroup analyses find that tamsulosin provides a superior expulsion rate for stones >5mm, but no effect for stones ≤5mm. In this report, we looked at the efficacy and safety of tamsulosin for the treatment of distal ureteral stones. We find that tamsulosin significantly facilitates the passage of distal ureteral stones and relieves renal colic. Copyright © 2017 European Association of Urology. Published by Elsevier B.V.

A simple, sensitive and robust method to extract tamsulosin from human serum, and quantify by liquid chromatography–tandem mass spectrometry (LC–MS/MS) was developed and validated and is applicable as a measure of compliance in clinical research. Tamsulosin was extracted from human serum (100 μL) via liquid–liquid extraction with methyl tert-butyl ether (2 mL) following dilution with 0.1 M ammonium hydroxide (100 μL), achieving 99.9% analyte recovery. Internal standard, d9-finasteride, was synthesised in-house. Analyte and internal standard were separated on an Ascentis® Express C18 (100 mm × 3 mm, 2.7 μm) column using a gradient elution with mobile phases methanol and 2 mM aqueous ammonium acetate (5:95, v/v). Total run-time was 6 min. Tamsulosin was quantified using a triple quadrupole mass spectrometer operated in multi-reaction-monitoring (MRM) mode using positive electrospray ionisation. Mass transitions monitored for quantitation were: tamsulosin m/z 409 → 228 and d9-finasteride m/z 382 → 318, with the structural formulae of ions confirmed by Fourier transform ion cyclotron resonance mass spectrometry (within 10 ppm). The limit of quantitation was 0.2 ng/mL, and the method was validated in the linear range 0.2–50 ng/mL with acceptable inter- and intra-assay precision and accuracy and stability suitable for routine laboratory practice. The method was successfully applied to samples taken from research volunteers in a clinical study of benign prostatic hyperplasia. PMID:23743242

The bioavailability of two 0.4 mg tamsulosin sustained-release film-coated tablet formulations was compared; using generic tablets (Prostam(®)) as test formulation and the originator product as reference formulation. Twenty-four subjects were included in this single-dose, open-label, randomized two-way crossover design following an overnight fasting. A one-week wash-out period was applied. Blood samples were drawn up to 72 h following drug administration. Plasma concentration of tamsulosin was determined by liquid chromatography-tandem mass spectrometry method with TurboIonSpray mode. Pharmacokinetic parameters AUC(0-t,) AUC(0-∞), C (max) and t (½) were determined and used for bioequivalence evaluation after log-transformation, whereas t (max) ratios were evaluated non-parametrically. The estimated point and 90% confidence intervals (CI) for AUC(0-t,) AUC(0-∞), C (max) and t (½) were 109.55% (96.41-124.49%), 109.94% (96.85-124.81%), 105.87% (92.88-120.67%) and 100.00% (90.56-110.43%), respectively. These results indicated that the two formulations of tamsulosin were bioequivalent; therefore they may be prescribed interchangeably.

α-Blockers induce selective relaxation of ureteral smooth muscle with subsequent inhibition of ureteral spasms and dilatation of the ureteral lumen. The aim of the study was to evaluate the efficacy and safety of the α-blocker tamsulosin hydrochloride in patients with ureteral colic owing to a distal ureteral stone. This was a multicenter, placebo-controlled, randomized, double-blind study. Patients with emergency admission for ureteral colic with a 2- to 7-mm-diameter radio-opaque distal ureteral stone were included in the study. They received tamsulosin (0.4 mg/d) or matching placebo until stone expulsion or day 42, whichever came first. The main end point was time to stone expulsion between inclusion and day 42. Sequential statistical analysis was performed using the triangular test. A total of 129 patients with acute renal colic were recruited from emergency wards between February 1, 2002, and December 8, 2006, in 6 French hospitals. Of these 129 randomized patients (placebo, 63; tamsulosin, 66), 7 were excluded from analyses: 5 for major deviations from inclusion criteria, 1 for stone expulsion before the first treatment administration, and 1 for consent withdrawal. At inclusion, mean (SD) stone diameters were 3.2 (1.2) and 2.9 (1.0) mm in the placebo and tamsulosin groups, respectively (P = .23). Expulsion delay distributions during 42 days did not show any difference (P = .30). The numbers of patients who spontaneously expelled their stone within 42 days were 43 of 61 (70.5%) and 47 of 61 (77.0%) in the placebo and tamsulosin groups, respectively (P = .41). Corresponding delays were 10.1 (10.0) and 9.6 (9.8) days (P = .82). Other secondary end points and tolerance were not different between groups. Although well tolerated, a daily administration of 0.4 mg of tamsulosin did not accelerate the expulsion of distal ureteral stones in patients with ureteral colic. clinicaltrials.gov Identifier: NCT00151567.

Full Text Available Mischel G Neill, Rohan Shahani, Alexandre R ZlottaDivision of Urology, Department of Surgical Oncology, Princess Margaret and Mount Sinai Hospitals, University of Toronto, Toronto, CanadaAbstract: The efficacy of tamsulosin at the cost of a relatively benign side effect profile has been attributed to receptor selectivity directed at the α1a and α1d adrenergic receptor subtypes. The oral-controlled absorption system (OCAS® represents a drug delivery refinement that incorporates a matrix of gel-forming and gel-enhancing agents to promote a constant drug release independent of environmental food or fluid. There are clinical data to support the concept that drug peaks are lessened and that drug release continues throughout the alimentary tract due to the OCAS formulation. Furthermore this equates with less adverse effects on physiologic parameters. To date however improvements in cardiovascular symptoms such as dizziness, headache and syncope have not been demonstrated in healthy men. Ejaculatory dysfunction appears less problematic with the OCAS preparation. Tamsulosin OCAS may be of greatest benefit to men with cardiovascular co-morbidities taking anti-hypertensive medications that might predispose them to symptomatic hypotensive episodes. It will be necessary to evaluate this group of men more closely in further trials to determine what they stand to gain from changing medications, and then relate this to drug costs to draw a final conclusion as to the place of tamsulosin OCAS in contemporary urological practice.Keywords: lower urinary tract symptoms, benign prostatic hyperplasia, tamsulosin OCAS, safety, efficacy, tolerability

The relative bioavailabilities of dutasteride/tamsulosin hydrochloride 0.5 mg/0.2 mg fixed-dose combination (FDC) capsules compared with coadministered reference products (1 dutasteride 0.5-mg capsule [Avodart ® ] + 1 tamsulosin hydrochloride 0.2-mg orally disintegrating tablet [Harnal D ® ]) were investigated in 2 clinical trials under fasted and fed conditions (ClinicalTrials.gov NCT02184585 and NCT02509104). Both trials were open-label, randomized, single-dose, crossover studies in healthy male adults aged 18-65 years. Trial 1 evaluated 2 formulations (FDC1 and FDC2), and trial 2 evaluated a third formulation (FDC3). The primary end points were dutasteride area under the concentration-time curve from time 0 to t (AUC (0-t) ) and peak plasma concentration (C max ) and tamsulosin AUC (0-∞) , AUC (0-t) , and C max . The formulations were considered to be bioequivalent if the 90%CIs for the geometric mean ratios for each end point were within the range of 0.80-1.25. For FDC1 in trial 1, bioequivalence criteria were not met for dutasteride C max or AUC in the fasted state or for tamsulosin C max in the fasted or fed states. For FDC2 in trial 1, all bioequivalence criteria were met except for tamsulosin C max in the fasted state. For FDC3 in trial 2, bioequivalence criteria were met for all dutasteride and tamsulosin end points in both the fed and fasted states. Safety profiles were similar for all FDC formulations and combination treatments. © 2017, The American College of Clinical Pharmacology.

The pregnane X receptor (PXR) is a transcription factor regulating P-glycoprotein (P-gp; ABCB1)-mediated transport and cytochrome P450 3A4 (CYP3A4)-mediated metabolism of xenobiotics thereby affecting the pharmacokinetics of many drugs and potentially modulating clinical efficacy. Thus, pharmacokinetic drug-drug interactions can arise from PXR activation. Here, we examined whether the selective α1-adrenoreceptor blocker tamsulosin or the antagonist of muscarinic receptors tolterodine affect PXR-mediated regulation of CYP3A4 and of P-gp at the messenger RNA (mRNA) and protein level in an enantiomer-specific way. In addition, the effect of tamsulosin and tolterodine on P-gp activity was evaluated. We used quantitative real-time PCR, gene reporter assay, western blotting, rhodamine efflux assay, and calcein assay for determination of expression, activity, and inhibition of P-glycoprotein. The studied compounds significantly and concentration-dependently increased PXR activity in the ABCB1-driven luciferase-based reporter gene assay. We observed much stronger induction of ABCB1 mRNA by S-tamsulosin as compared to the R or racemic form. R or racemic form of tolterodine and R-tamsulosin concentration-dependently increased P-gp protein expression; the latter also enhanced P-gp efflux function in a rhodamine-based efflux assay. R-tamsulosin and all forms of tolderodine slightly inhibited P-gp. The effect on CYP3A4 expression followed the same pattern but was much weaker. Taken together, tamsulosin and tolterodine are demonstrated to interfere with P-gp and CYP3A4 regulation in an enantiomer-specific way.

Administration of nifedipine or tamsulosin has been suggested to augment stone expulsion rates. We aimed to compare the stone expulsion rates and adverse effects associated with the use of nifedipine or tamsulosin as medical expulsive therapy (MET) for the management of lower ureteral stones (LUS) without extracorporeal shock wave lithotripsy (ESWL) via a literature review and meta-analysis. Relevant randomized controlled trials (RCTs) were identified from the Medline, EMBASE, Cochrane CENTRAL, and Google Scholar databases. Finally, a total of 7 RCTs with 3897 patients were included. Our meta-analysis showed that tamsulosin could significantly increase the stone expulsion rate relative to nifedipine in patients with LUS (random-effects model; risk ratio [RR] = 0.81; 95% confidence interval [CI] = 0.75-0.88; P < 0.00001). The subgroup analysis indicated no statistically significant difference between the drugs with regard to minor or major adverse effects (fixed-effect model; RR = 1.19, 95% CI = 0.91-1.54, P = 0.20; and RR = 1.63, 95% CI = 0.22-11.82, P = 0.63, respectively). This meta-analysis demonstrated that tamsulosin was more effective than nifedipine in patients with LUS, as evidenced by the higher stone expulsion rate. Tamsulosin treatment should therefore be considered for patients with LUS.

Urinary retention is a common complication of pelvic surgery, leading to urinary tract infection and prolonged hospital stays. Tamsulosin is an alpha blocker that works by relaxing bladder neck muscles. It is used to treat benign prostatic hypertrophy and retention. We aim to investigate the potential benefits of preemptive tamsulosin use on rates of urinary retention in men undergoing pelvic surgery. This is a retrospective review of an institutional colorectal database. All men undergoing pelvic surgery between 2004 and 2013 were included. Patients given 0.4 mg of tamsulosin 3 days prior and after surgery at discretion of surgeon starting in 2007 were compared with patients receiving expectant postoperative management. One hundred eighty-five patients were included in the study (study group: N = 30; control group: N = 155). Study group patients were older (56.8 vs. 50.1 years). Overall urinary retention rate was 22% with significantly lower rates in the study group compared with control (6.7 vs. 25%; p = 0.029). Study group had higher rates of minimally invasive surgery (61 vs. 29.7%); however, this did not impact urinary retention rate (20.6 vs. 22.7% for minimally invasive surgery vs. open surgery; p = 0.85). Independent predictors of urinary retention included lack of preemptive tamsulosin (odds ratio (OR), 7.67; 95% confidence interval (CI), 1.4-41.7) and cancer location in the distal third of the rectum (OR, 18.8; 95% CI, 2.1-172.8). Preemptive perioperative use of tamsulosin may significantly decrease the incidence of urinary retention in men undergoing pelvic surgery. This may play a role in avoidance of urinary retention, particularly in patients with distal rectal cancer.

Ureteral stenting is associated with various morbidity and reduced quality of life. We systematically evaluated the efficacy and safety of solifenacin as monotherapy, or combined therapy with tamsulosin versus control or tamsulosin monotherapy in stent-related symptoms (SRSs). Randomized controlled trials evaluating solifenacin or its combination with tamsulosin for the treatment of SRSs were identified via a comprehensive search of Pubmed, Embase, Ovid, The Cochrane Library and relevant sources up to February 2017. Ureteral stent symptom questionnaire (USSQ) and drug-related complications were pooled for meta-analysis. Mean difference and risk difference were calculated as appropriate for each outcome to determine the cumulative effect size. There were 10 studies involving 1786 participants finally eligible in the quantitative analysis. Solifenacin monotherapy significantly reduced the total score of USSQ [MD -14.90; 95% CI (-25.19, -4.60); P = 0.005], as well as indexes of urinary symptoms, body pain, general health, sexual performance, and hematuria (P = 0.02, P = 0.009, P = 0.004, P = 0.02, P = 0.02, respectively), but the differences were insignificant when compared with tamsulosin except improved sexual performance (P = 0.004). Combined therapy of solifenacin and tamsulosin showed no beneficial effects in all indexes of USSQ over solifenacin monotherapy. Only slightly higher incidence of dry mouth (P = 0.02) was found with solifenacin versus control. The result demonstrates the safety and efficacy of solifenacin in reducing SRSs, but no significant advantage was found over tamsulosin. In addition, combination of solifenacin and tamsulosin did not show beneficial effects over solifenacin monotherapy. More high quality trials are warranted to further address this issue, however.

Lower urinary tract symptoms (LUTS) associated with benign prostatic hyperplasia (BPH) and erectile dysfunction are common disorders of advancing age. To evaluate the efficacy and safety of tamsulosin and tadalafil in patients with LUTS due to BPH. In this prospective randomized study, 133 men complaining of LUTS due to BPH were included. Forty-five patients received tamsulosin 0.4 mg/day alone (Group A), 44 patients received tadalafil 10 mg/day (Group B), and combination therapy (tamsulosin and tadalafil both) was instituted in 44 patients (Group C). After a 2-week medication free run-in period, they were evaluated for International Prostatic Symptom Score (IPSS), International Index of Erectile Function score (IIEF5), quality of life (IPSS QoL), maximum urinary flow rate (Qmax), post-void residual urine (PVR) volume, and safety parameters before and at 3 months of treatment. There were primary (IPSS, IPSS QoL index, Qmax, and PVR) and secondary (erectile function [EF] domain scores from IIEF5) efficacy end points. Safety assessment included laboratory tests and patient's reporting of adverse event. A significant improvement in IPSS score was observed in all the 3 groups A, B, and C (-50.90%, P tamsulosin and tadalafil alone or in combination cause a significant improvement in patients with LUTS. Their EF also improves with these medications. The improvement is better with combination therapy compared with single agent alone. © 2013 International Society for Sexual Medicine.

To understand the mechanisms underlying ejaculation dysfunction caused by α1A-adrenocetor (AR) antagonists, the effects of α1A-AR antagonists on the contractile responses of the seminal vesicle were investigated. Isolated seminal vesicles from guinea pigs were cannulated and pressurized, and the changes in the intraluminal pressure were recorded. Periodic applications of electrical stimulation (ES) caused biphasic increase in the intraluminal pressure, that is, initial and subsequent contractions. The effects of silodosin and tamsulosin, α1A-AR antagonists, on the contractile responses were examined. The ES-induced biphasic contractions were blocked by tetrodotoxin (TTX). Silodosin and tamsulosin suppressed the initial contractions in a dose-dependent manner, while also exerting various inhibitory effects on the subsequent contractions. Increases in the intraluminal pressure facilitated spontaneous phasic contractions. The spontaneous contractions were not affected by TTX or α1A-AR antagonists, but were abolished by nifedipine. The initial contractions triggered by neuronal excitations were suppressed by silodosin and tamsulosin, suggesting that the ejaculation dysfunction may be attributed to the α1A-AR antagonist-mediated suppression of nerve-evoked contractions in the seminal vesicle. The subsequent contractions may be induced by mechanical stimulation associated with the initial, nerve-evoked contractions. Alternatively, other transmitters may be involved to various degrees in the neuromuscular transmission of the seminal vesicle. © 2014 Wiley Publishing Asia Pty Ltd.

Reversible exacerbation of obstructive sleep apnea by α1-adrenergic blockade with tamsulosin: A case report.

Science.gov (United States)

Moran, Mark

2016-01-01

Obstructive sleep apnea (OSA) is characterized by repeated involuntary closure of the pharyngeal airspace during sleep. Normal activity of the genioglossus (GG) muscle is important in maintaining airway patency, and inhibition of GG activity can contribute to airway closure. Neurons in the hypoglossal motor nucleus (HMN) regulate GG activity. Adrenergic tone is an important regulator of HMN neuronal excitability. In laboratory models α 1 -adrenergic antagonists inhibit HMN neurons and GG activity, suggesting that α 1 -adrenergic antagonism might adversely affect patients with OSA. To date there has been no report of such a case. The patient was a 67-year old man with a 27-month history of obstructive sleep apnea. Diagnostic polysomnography demonstrated a baseline apnea-hypopnea index (AHI) of 21.3 and a trough oxygen saturation of 84%. Treatment with continuous positive airway pressure (CPAP) was initiated. The AHI in year 1 averaged 1.0 ± 0.1 (mean ± SD) and 0.8 ± 0.1 in year 2. Other medical conditions included hypertension controlled with losartan and benign prostatic hypertrophy not well controlled by finasteride monotherapy. The α 1 -adrenergic receptor antagonist tamsulosin 0.4 mg daily was added. Shortly after initiation of tamsulosin, subjective sleep quality deteriorated. Significant surges in obstructive events, apneic episodes, and AHI were also recorded, and nocturnal airway pressure was frequently sustained at the CPAP device maximum of 20 cm H 2 O. Tamsulosin was discontinued. CPAP parameters and sleep quality returned to the pre-tamsulosin baselines within 10 days. These findings suggest that α 1 -adrenergic blockade with tamsulosin may exacerbate sleep-disordered breathing in susceptible patients.

Full Text Available BACKGROUND The urinary stone disease is one of the most common afflictions of the modern society and it has been described since antiquity with the westernisation of global culture. It has led to a lot of distress physically, mentally and financially to the affected individuals. Mini-invasive techniques like ESWL and ureteroscopy have their own negative aspects with discomfort to the patient being the prime in it. Hence, a need for conservative management in the form of pharmacotherapy has arisen in the past years and here we are investigating the same. The aim of the study is to compare the efficacy of silodosin (8 mg vs. tamsulosin (0.4 mg both in terms of the stone expulsion rate and the time to stone expulsion. MATERIALS AND METHODS A study comprising of 120 patients between the age group of 18-50 years with sonography-proven unilateral, uncomplicated lower ureteric calculus was undertaken from January 2015 to November 2015. Exclusion criteria were calculus more than or equal to 1 cm. Patients were divided in 2 Groups; Group A received silodosin 8 mg once daily for a month while Group B received tamsulosin 0.4 mg once daily. The patients were followed up weekly or biweekly with imaging studies. The endpoint was the stone expulsion rate and time, the rate of the interventions and the side effects. Settings and Design- With ethical committee clearance, a prospective study was conducted in the Department of Urology, Mahatma Gandhi Medical College and Hospital, Jaipur, India. Statistical Analysis- The SPSS-16 software was used for the statistical analysis of the data. RESULTS Results of our analysis showed that Group A (silodosin patients were benefited more than Group B (tamsulosin and it was also backed by the data showing a statistical significance for spontaneous stone expulsion in favour of the silodosin group. CONCLUSION Hence, we concluded that silodosin’s efficacy in treating patients with distal ureteric calculus was much better when

Purpose To evaluate how much the improvement of lower urinary tract symptoms (LUTS) affects sexual function and which storage symptoms or voiding symptoms have the greatest effect on sexual function. Materials and Methods A total of 187 patients were enrolled in this study. Patients were randomly assigned to receive either tamsulosin 0.2 mg (group A) or tamsulosin 0.2 mg and solifenacin 5 mg (group B). At 4 weeks and 12 weeks, the LUTS and sexual function of the patients were evaluated by use of the International Index of Erectile Function-5 (IIEF5), International Prostate Symptom Score (IPSS), Overactive Bladder Symptom Score (OABSS) questionnaire, uroflowmetry, and bladder scan. Results Both groups A and B showed statistically significant improvements in IPSS, OABSS, and quality of life (QoL). Group A showed improved maximum flow rate, mean flow rate, and residual urine volume by time. Group B did not show an improvement in flow rate or residual urine volume but total voiding volume increased with time. The IIEF5 score was not improved in either group. In group A, the IIEF5 score dropped from 13.66±4.97 to 11.93±6.14 after 12 weeks (p=0.072). Group B showed a decline in the IIEF5 score from 13.19±5.91 to 12.45±6.38 (p=0.299). Although group B showed a relatively smaller decrease in the IIEF5 score, the difference between the two groups was not significant (p=0.696). Conclusions Tamsulosin monotherapy and combination therapy with solifenacin did not improve erectile function despite improvements in voiding symptoms and QoL. The improvement in storage symptoms did not affect erectile function. PMID:25237463

Medical expulsive therapy is based on pharmacologic ureteral relaxation. We hypothesized this concept may facilitate the deployment of the large 16 French (F) ureteral access sheath (UAS) when patients are intentionally pre-treated with oral tamsulosin, i.e., medical impulsive therapy. We retrospectively analyzed our experience with UAS deployment during endoscopic-guided percutaneous nephrolithotomy in prone position in patients pre-treated for 1 week with oral tamsulosin with a contemporary untreated cohort. Between January 2015 and September 2016, seventy-seven patients without a pre-existing ureteral stent met inclusion criteria. Demographic data, tamsulosin usage, UAS size, deployment failure, ureteral injuries, stone-free rates, and complications were recorded. Univariate and multivariate analysis was conducted to assess the impact of tamsulosin on deployment of the 16F UAS. There was no statistical difference between the tamsulosin (n = 40) group and non-tamsulosin (n = 37) group in regard to demographic data. The tamsulosin group had a significantly higher percentage of 16F UAS deployment, 87 vs. 43% (p < 0.001), and no significant difference in ureteral injuries (p = 0.228). Univariate and multivariate analysis revealed that tamsulosin significantly increased the odds ratio (9.3 and 19.4, respectively) for successful passage of a 16F UAS. Despite a larger stone volume, there was no significant difference in computed tomography scan complete stone-free rates (29 vs. 42%; p = 0.277) at median post-operative time of only 3 days. In this retrospective study, 1 week of preoperative tamsulosin was associated with an increase in the deployment of a 16F UAS in patients without preoperative ureteral stent placement.

This study was carried out a network meta-analysis of evidence from randomized controlled trials (RCTs) to evaluate stent-related discomfort in patients with alfuzosin or tamsulosin versus placebo. Relevant RCTs were identified from electronic databases. The proceedings of appropriate meetings were also searched. Seven articles on the basis of RCTs were included in our meta-analysis. Using pairwise and network meta-analyses, comparisons were made by qualitative and quantitative syntheses. Evaluation was performed with the Ureteric Stent Symptoms Questionnaire to assess the urinary symptom score (USS) and body pain score (BPS). One of the seven RCTs was at moderate risk of bias for all quality criteria; two studies had a high risk of bias. In the network meta-analysis, both alfuzosin (mean difference [MD];-4.85, 95 % confidence interval [CI];-8.53--1.33) and tamsulosin (MD;-8.84, 95 % CI;-13.08--4.31) showed lower scores compared with placebo; however, the difference in USS for alfuzosin versus tamsulosin was not significant (MD; 3.99, 95 % CI;-1.23-9.04). Alfuzosin (MD;-5.71, 95 % CI;-11.32--0.52) and tamsulosin (MD;-7.77, 95 % CI;-13.68--2.14) showed lower scores for BPS compared with placebo; however, the MD between alfuzosin and tamsulosin was not significant (MD; 2.12, 95 % CI;-4.62-8.72). In the rank-probability test, tamsulosin ranked highest for USS and BPS, and alfuzosin was second. The alpha-blockers significantly decreased USS and BPS in comparison with placebo. Tamsulosin might be more effective than alfuzosin.

Tamsulosin 0.2 mg is used widely in Asian people, but the low dose has been studied less than tamsulosin 0.4 mg or other alpha blockers of standard dose. This study investigated the efficacy and safety of tamsulosin 0.2 mg by a meta-analysis and meta-regression. We conducted a meta-analysis of efficacy of tamsulosin 0.2 mg using International Prostate Symptom Score (IPSS), maximal urinary flow rate (Qmax), post-voided residual volume (PVR), and quality of life (QoL). Safety was analyzed using adverse events. Relevant studies were searched using MEDLINE, EMBASE, and Cochrane library from January 1980 to June 2013. Ten studies were included with a total sample size of 1418 subjects [722 tamsulosin 0.2 mg group and 696 other alpha-blockers (terazosin, doxazosin, naftopidil, silodosin) group]. Study duration ranged from 4 to 24 weeks. The pooled overall standardized mean differences (SMD) in the mean change of IPSS from baseline for the tamsulosin group versus the control group was 0.02 [95% confidence interval (CI); -0.20, 0.25]. The pooled overall SMD in the mean change of QoL from baseline for the tamsulosin group versus the control group was 0.16 (95% CI; -0.16, 0.48). The regression analysis with the continuous variables (number of patients, study duration) revealed no significance in all outcomes as IPSS, QoL, and Qmax. This study clarifies that tamsulosin 0.2 mg has similar efficacy and fewer adverse events compared with other alpha-blockers as an initial treatment strategy for men with lower urinary tract symptoms.

The obstruction of the urinary tract by calculi at the narrowest anatomical areas leads to impaired drainage and severe pain. The aim of this study was to evaluate a new technology, extracorporeal physical vibrational lithecbole (EPVL) combined with tamsulosin, as a treatment for distal ureteral calculi (DUC). Between July 2013 and July 2014, 672 patients diagnosed with DUC were randomly divided into three groups; a group receiving EPVL plus 0.4 mg oral tamsulosin daily (PO qd) (experimental group, n = 236), a group receiving 0.4 mg tamsulosin PO qd (n = 222), and a group receiving EPVL only (n = 214) (control groups). There were no significant differences in general characteristics between the three groups. Stone diameters ranged from 0.32 to 1 cm. In the EPVL plus tamsulosin group, 60.1% of patients showed detectable fragment expulsion at 48 hours, and 91.1% were stone free at 7 days. Compared with the two control groups, these rates were significantly higher (EPVL group was 0% and 50.5% and medical expulsive therapy group was 0% and 50.0%, p  0.05). Patients in the EPVL plus tamsulosin group achieved similar stone-free rates compared with the other two groups, but the speed of the stone expulsion was quicker for both sexes and all age groups (about a week; p tamsulosin could be used as an effective, but faster treatment option for patients with DUC, alleviating the symptoms of DUC in a shorter period of time.

Benign prostatic hyperplasia (BPH) impacts quality of life in men by causing lower urinary tract symptoms. α1-Adrenoceptor (α1-AR) blockers improve lower urinary tract symptoms. We investigated the efficacy of add-on therapy with α1-AR blockers on BPH rats. Rats in the drug-treated groups were orally administered each drug once a day for 30 days after orchiectomy. To induce BPH, rats were castrated and testosterone (20 mg/kg) was injected subcutaneously once per day for 30 days. Cystometry was conducted to measure voiding contraction pressure and the interval contraction time, immunohistochemistry was performed to measure c-Fos and nerve growth factor (NGF) expression in the neuronal voiding centers, and nicotinamide adenine dinucleotide phosphate-diaphorase histochemistry was used to measure nitric oxide synthase (NOS) expression. Orchiectomy and testosterone injection decreased voiding contraction pressure and the interval contraction time, suggesting BPH symptoms. Voiding contraction pressure and the interval contraction time were greater in the group that received the combination treatment (tamsulosin with naftopidil) than in the tamsulosin monotherapy or naftopidil monotherapy groups. c-Fos, NGF, and NOS expression in the neuronal voiding centers was enhanced by BPH induction. c-Fos, NGF, and NOS expression was suppressed by the combination treatment (tamsulosin with naftopidil) to a greater extent than was the case for tamsulosin monotherapy or naftopidil monotherapy. Combination therapy of tamsulosin and naftopidil showed greater efficacy for the treatment of BPH than tamsulosin monotherapy or naftopidil monotherapy; therefore, combination therapy can be considered as a novel therapeutic method for BPH.

AIM To determine the effect of the strong CYP2D6 inhibitor paroxetine and strong CYP3A4 inhibitor ketoconazole on the pharmacokinetics and safety (orthostatic challenge) of tamsulosin. METHODS Two open-label, randomized, two-way crossover studies were conducted in healthy male volunteers (extensive CYP2D6 metabolizers). RESULTS Co-administration of multiple oral doses of 20 mg paroxetine once daily with a single oral dose of the 0.4 mg tamsulosin HCl capsule increased the adjusted geometric mean (gMean) values of Cmax and AUC(0,∞) of tamsulosin by factors of 1.34 (90% CI 1.21, 1.49) and 1.64 (90% CI 1.44, 1.85), respectively, and increased the terminal half-life (t1/2) of tamsulosin HCl from 11.4 h to 15.3 h. Co-administration of multiple oral doses of 400 mg ketoconazole once dailywith a single oral dose of the 0.4 mg tamsulosin increased the gMean values of Cmax and AUC(0,∞) of tamsulosin by a factor of 2.20 (90% CI 1.96, 2.45) and 2.80 (90% CI 2.56, 3.07), respectively. The terminal half-life was slightly increased from 10.5 h to 11.8 h. These pharmacokinetic changes were not accompanied by clinically significant alterations of haemodynamic responses during orthostatic stress testing. CONCLUSION The exposure to tamsulosin is increased upon co-administration of strong CYP2D6 inhibitors and even more so of strong 3A4 inhibitors, but neither PK alteration was accompanied by clinically significant haemodynamic changes during orthostatic stress testing.

In a prospective study, 161 patients with DJ related symptoms were randomized into 3 groups: Group A patients (54, Group B patients (53, and Group C patients (54. They were given Tadalafil, Tamsulosin, and placebo, respectively, at 1st week till removal of DJ stent at 3rd week. All patients completed Ureteral Stent Symptom Questionnaire (USSQ at 1st week and at 3rd week. The statistical significant difference among groups was determined by the t-test, Kruskal-Wallis test and multivariate analysis were used to assess association of the variables within the three groups, and the level of significance was set at P<0.05. Results. Tadalafil and Tamsulosin were comparable in relieving urinary symptoms, general health, and work performance (OR = 0.65, 1.8, and 0.92. But Tadalafil was more effective in relieving body pain, sexual problems, and additional problems than Tamsulosin (OR = 5.95, 19.25, and 2.69 and was statistically significant as P<0.05. Conclusion. Tadalafil was as effective as Tamsulosin in relieving urinary symptom but more effective in relieving sexual symptoms and body pain.

Many studies have been conducted to investigate adjunctive tamsulosin therapy after extracorporeal shockwave lithotripsy (SWL) for urolithiasis. The results from those studies, however, are still inconsistent. Therefore, we performed a meta-analysis to provide an update on the clinical efficacy and safety of tamsulosin combined with SWL for urolithiasis. A systematic search was performed in PubMed, Cochrane Library, and Embase to identify all relevant randomized controlled trials until January 2015. Two reviewers independently assessed trial quality and extracted data. Meta-analysis was conducted with Review Manager (RevMan), version 5.1. Twenty-one studies (2093 subjects in total) were identified in the current meta-analysis. Compared with a control group, the experimental group (tamsulosin combined with SWL) showed an increased overall benefit for stone expulsion, with pooled risk ratio (RR) of 1.20 (95% confidence interval [CI], 1.15-1.26). With respect to the different geographic regions, European and American had a high possibility of improvement in stone expulsion (RR: 1.33, 95% CI, 1.19-1.49). According to the stone locations (renal, upper and lower ureteral) and sizes (4-10 mm and 11-24 mm), tamsulosin is more useful for lower ureteral stone (RR: 1.28; 95% CI, 1.14-1.43) and larger sized stones (RR: 1.49; 95% CI, 1.28-1.75). The effect estimates did not vary markedly when stratified by follow-up durations but varied by dose of tamsulosin. Furthermore, a shorter expulsion time, reduced occurrence of steinstrasse, fewer incidences of colic, and lower analgesic requirements were observed within the experimental group. In addition, tamsulosin is well tolerated, and its adverse events rarely led to dropouts of patients. Overall, evidence suggests that tamsulosin combined with SWL is safe and effective in enhancing stone expulsion for patients with urolithiasis. Furthermore, high-quality, randomized and placebo-controlled trials evaluating the efficacy and

Full Text Available ABSTRACT Introduction and objective Indwelling double J ureteral stents are used routinely in the resolution of ureteral obstruction caused by different etiologies. Evaluation of urinary symptoms related to double-J stent, indicate that these affect 73-90% of patients. We conducted a prospective, randomized study, to evaluate the efficacy of tamsulosin, oxybutinin and combination therapy in improving the urinary symptoms. Methods Patients who underwent ureteral stent placement after ureterolithotripsy (total 51, were randomized into three groups: Group I: Tamsulosin 0.4 mg. once per day(17 patients, Group II: Oxybutinin 5 mg. once per day (17 patients, Group III: Tamsulosin+ oxybutynin once per day (17 patients. All the groups received the drugs for three weeks and completed a Spanish validated Ureteral Stent Symptom Questionnaire (USSQ at day 7 and 21. Results Repeated measures ANOVA showed mean urinary symptom index score was 22.3 vs. 15.5 in group three (p<0.001 at day 7 and 21 respectively. The mean work performance index was 6.6 vs 8.1 (p=0.049 favoring tamsulosin group, the mean sexual score was 0.5 vs 1.5 (p=0.03. Among additional problems the mean was 7.2 vs 6.2 (p=0.03. No significant difference was noted among pain and general health index. No side effects were reported. Conclusions Combination therapy with tamsulosin and oxybutynin improved irritative symptoms and work performance as well as sexual matters. Combination therapy should be considered for patients who complained of stent related symptoms.

To investigate the effects of combined treatment of tadalafil (a phosphodiesterase-5 inhibitor) and tamsulosin (an α 1 -adrenoceptor antagonist) on bladder dysfunction in a rat model of bladder outlet obstruction (BOO). Cystometry was performed in conscious female BOO rats 6 weeks after partially ligation of the urethra. Either tadalafil (0.03, 0.1 and 0.3 mg/kg) or tamsulosin (0.001, 0.003 and 0.01 mg/kg) was cumulatively applied intravenously at 30-min intervals to examine changes in cystometric parameters and blood pressures. Changes in cystometric parameters and blood pressures were also checked when tadalafil (0.3 mg/kg), tamsulosin (0.003 mg/kg) or both were intravenously applied. In BOO rats, application of either tadalafil (0.3 mg/kg) or tamsulosin (0.003, 0.01 mg/kg) alone significantly increased threshold pressures and intercontraction intervals whereas there were no significant changes in other cystometric parameters. In addition, because a significant reduction in blood pressures was detected after the administration of tamsulosin (0.01 mg/kg), tamsulosin at a lower dose (0.003 mg/kg) was used for the combined treatment. The combination therapy of tadalafil and tamsulosin induced a significantly larger rate of increase in intercontraction intervals (1.7 times) compared with monotherapy of either drug (1.3 times each) although the combined therapy did not affect blood pressures. These results suggest that the combination therapy of tadalafil and tamsulosin can induce the additive inhibitory effects on urinary frequency compared with monotherapy, more likely via inhibition of the afferent limb of micturition reflex rather than the efferent function as evidenced by the increases in threshold pressures and intercontraction intervals without affecting bladder contractile function.

To compare the efficacies of naftopidil and tamsulosin in terms of reducing storage symptoms in patients with benign prostatic hyperplasia. This prospective randomized study was performed at 10 centers. Ninety-four patients that had been taking tamsulosin for more than 8 weeks, but had an Overactive Bladder Symptom Score (OABSS) of greater than 3 points, were initially enrolled. After a 1-week washout period, patients were divided into 2 groups. Forty-five patients were treated with tamsulosin 0.2 mg daily, and 49 patients were treated with naftopidil 75 mg daily for 8 weeks. Total International Prostate Symptoms Score (IPSS), storage symptom scores, nocturia times, OABSS, maximal flow rates (Q max ), and postvoid residual volumes were checked before and after the 8-week treatment period. Mean patient ages in the tamsulosin and naftopidil groups were 64.8 and 66.0 years, respectively. Baseline characteristics were not significantly different. In the tamsulosin group, mean total IPSS decreased from 19.1 to 15.1 after the 8-week treated period (P = .001), and in the naftopidil group, mean total IPSS decreased from 16.9 to 13.1 (P = .001). Mean storage symptom scores were reduced in the tamsulosin and naftopidil groups from 8.0 to 6.6 (P = .002) and from 7.6 to 6.1 (P = .001), respectively. Mean nocturia times in the naftopidil groups decreased significantly from 2.5 to 1.9 (P = .001), and mean OABSSs were reduced from 7.7 to 6.0 (P = .001) and from 7.4 to 6.0 (P = .001), respectively. Total IPSS, storage symptom scores, nocturia times, and OABSS were significantly reduced by naftopidil and tamsulosin. Moreover, the naftopidil group showed better improvements in nocturia than the tamsulosin group. Copyright © 2017 Elsevier Inc. All rights reserved.

To explore the rate of add-on therapy with solifenacin in men with voiding and storage lower urinary tract symptoms (LUTS) after tamsulosin monotherapy and to explore predictive factors for starting solifenacin add-on therapy. Men aged ≥ 45 years with IPSS ≥ 12 and symptoms of OAB (OAB-V8 ≥ 8, micturition ≥ 8/24 h, urgency ≥ 2/24 h) were enrolled to receive tamsulosin 0.2 mg once daily. After 4 weeks, men with residual symptoms of OAB and reported 'dissatisfied' or 'a little satisfied' were received solifenacin 5 mg in combination with tamsulosin monotherapy. Subjects completed an IPSS, a Quality of life (QoL) index, OAB V8, and an International Consultation of Incontinence Questionnaire (ICIQ)-Male LUTS, and patient perception of bladder condition (PPBC) at baseline and week 4. Of a total of 305 patients, 254 patients completed 4 weeks of tamsulosin treatment. For 176 patients, solifenacin was added (69.3%). Significant predictive factors of solifenacin add-on therapy included long LUTS duration, high IPSS, number of micturitions per 24 h, more urgency episodes, high urgency severity score in a voiding diary and high OAB V8 score. Based on multivariable analysis, potential predictive factors of solifenacin add-on therapy included long LUTS duration (OR = 1.008, 95% CI: 1.001-1.014), high serum PSA (OR = 1.543, 95% CI: 1.136-2.095) and small prostate size (OR = 0.970, 95% CI: 0.947-0.994) (p tamsulosin monotherapy. Two thirds of men with voiding and storage LUTS needed to add anticholinergics after 4 weeks of tamsulosin monotherapy. Patients with longer lasting symptoms and storage symptoms with small prostate volume may require the anticholinergic add-on. © 2014 John Wiley & Sons Ltd.

To evaluate the efficacy and safety of a combination therapy with dutasteride and imidafenacin in patients with benign prostatic hyperplasia and persistent overactive bladder symptoms. A total of 163 patients presenting an enlarged prostate (volume >30 mL) and persistent overactive bladder symptoms despite at least 8 weeks of tamsulosin were randomized to receive tamsulosin and dutasteride, or tamsulosin, dutasteride and imidafenacin at a 1:1 ratio. The primary end-point was the mean change from baseline to week 24 in total overactive bladder symptom score. The mean change in total overactive bladder symptom score from baseline at week 24 was -1.99 (95% confidence interval -2.57 to -1.41) in the tamsulosin and dutasteride group, and -3.12 (95% confidence interval -3.72 to -2.52) in the tamsulosin, dutasteride and imidafenacin group. The tamsulosin, dutasteride and imidafenacin group significantly improved total overactive bladder symptom score at week 24 as compared with the tamsulosin and dutasteride group; the mean difference was -1.18 (-2.02 to -0.34). The between-group difference was statistically significant as early as week 4. The total International Prostate Symptom Score, storage subscore, quality of life index, and benign prostatic hyperplasia impact index also significantly improved in the tamsulosin, dutasteride and imidafenacin group. Tamsulosin, dutasteride and imidafenacin combination therapy improves overactive bladder symptoms and quality of life without causing serious adverse drug reactions in patients with enlarged prostate not responding to tamsulosin. This combination therapy seems to represent a promising therapeutic option in these patients. © 2017 The Japanese Urological Association.

Introduction: We estimate the lifetime cost of treatment for moderate/severe symptoms associated with benign prostatic hyperplasia (BPH) in a cohort of Canadian men aged 50 to 59, and we evaluate the costs of 2 daily bioequivalent treatment options: fixed-dose combination (FDC) of dutasteride (0.5 mg) and tamsulosin (0.4 mg), or concomitant administration of dutasteride (0.5 mg) and tamsulosin (0.4 mg) monotherapies. Methods: The expected lifetime costs were estimated by modelling the incidence of acute urinary retention (AUR), BPH-related surgery and clinical progression over a patient’s lifetime (up to 25 years). A model was developed to simulate clinical events over time, based on a discrete Markov process with 6 mutually exclusive health states and annual cycle length. Results: The estimated lifetime budget cost for the cohort of 374 110 men aged 50 to 59 in Canada is between $6.35 billion and $7.60 billion, equivalent to between $16 979 and $20 315 per patient with moderate/severe symptoms associated with BPH. Costs are lower for FDC treatment, with the net difference in lifetime budget impact between the 2 treatment regimens at $1.25 billion. In this analysis, the true costs of BPH in Canada are underestimated for 2 main reasons: (1) to make the analysis tractable, it is restricted to a cohort aged 50 to 59, whereas BPH can affect all men; and (2) a closed cohort approach does not include the costs of new (incident) cases. Conclusion: Canadian clinical guidelines recommend the use of the combination of tamsulosin and dutasteride for men with moderate/severe symptoms associated with BPH and enlarged prostate volume. This analysis, using a representational patient group, suggests that the FDC is a more cost-effective treatment option for BPH. PMID:24454593

The functions of the lower urinary tract (LUT), such as voiding and storing urine, are dependent on complex central neural networks located in the brain, spinal cord, and peripheral ganglia. Thus, the functions of the LUT are susceptible to various neurologic disorders including spinal cord injury (SCI). SCI at the cervical or thoracic levels disrupts voluntary control of voiding and the normal reflex pathways coordinating bladder and sphincter functions. In this context, it is noteworthy that α1-adrenoceptor blockers have been reported to relieve voiding symptoms and storage symptoms in elderly men with benign prostatic hyperplasia (BPH). Tamsulosin, an α1-adrenoceptor blocker, is also considered the most effective regimen for patients with LUT symptoms such as BPH and overactive bladder (OAB). In the present study, the effects of tamsulosin on the expression of c-Fos, nerve growth factor (NGF), and nicotinamide adenine dinucleotide phosphate-diaphorase (NADPH-d) in the afferent micturition areas, including the pontine micturition center (PMC), the ventrolateral periaqueductal gray matter (vlPAG), and the spinal cord (L5), of rats with an SCI were investigated. SCI was found to remarkably upregulate the expression of c-Fos, NGF, and NADPH-d in the afferent pathway of micturition, the dorsal horn of L5, the vlPAG, and the PMC, resulting in the symptoms of OAB. In contrast, tamsulosin treatment significantly suppressed these neural activities and the production of nitric oxide in the afferent pathways of micturition, and consequently, attenuated the symptoms of OAB. Based on these results, tamsulosin, an α1-adrenoceptor antagonist, could be used to attenuate bladder dysfunction following SCI. However, further studies are needed to elucidate the exact mechanism and effects of tamsulosin on the afferent pathways of micturition.

The objective of this study was to assess the efficacy of tamsulosin and finasteride monotherapies, and their combination in men with benign prostatic hyperplasia (BPH). This is a prospective single-blind randomized study of ninety men with BPH who were managed using drugs. The International Prostate Symptom Score (IPSS), peak urinary flow rate, and prostate volume were measured as parameters for assessment at the beginning, 3 months, and 6 months of the study. The mean age of patients was 61.65 with a range of 44-81 years. There was a progressive and sustained improvement in the IPSS score in all patient groups with mean decrease at 3 months of 7.24 (42.59%), 7.60 (41.85%), and 7.24 (40.61%) and at 6 months of 8.14 (47.88%), 10.33 (56.88%), and 11.1 (62.25%) in the tamsulosin, finasteride, and combination groups, respectively. There was an increase in peak urinary flow rate in all groups with mean increase at 3 months of 0.98, 0.05, and 3.55 (ml/s) and at 6 months of 4.11, 0.87, and 3.74 (ml/s) in the tamsulosin, finasteride, and combination groups, respectively. There was a reduction in the prostate volume in the finasteride and combination groups at 6 months of 6.8 and 6.32 cm 3 , respectively, while the tamsulosin group recorded an increase. At the end of 6 months, tamsulosin monotherapy and combination therapy appear to be equally effective in the treatment of lower urinary tract symptoms BPH while finasteride monotherapy appears to be the least effective. Bothersome, side effects were more in patients taking finasteride alone or as combination therapy.

This study aimed to compare the safety and efficacy of tamsulosin and tadalafil as medical expulsive therapy for distal ureteral stones. This prospective randomized study was conducted at the Department of Urology of Bir Hospital over a period of 12 months in patients with distal ureteral stones sized 5 to 10 mm. Patients were randomly divided into 2 groups: group A received tamsulosin 0.4 mg and group B received tadalafil 10 mg at bedtime for 2 weeks. Stone expulsion rate, number of ureteric colic episodes and pain score, analgesic requirements, and adverse drug effects were noted in both groups. Statistical analyses were performed by using Student t-test and chi-square test. Altogether 85 patients, 41 in group A and 44 in group B, were enrolled in the study. The patients' average age was 31.72±12.63 years, and the male-to-female ratio was 1.5:1. Demographic profiles, stone size, and baseline investigations were comparable between the 2 groups. The stone expulsion rate was significantly higher in the tadalafil group than in the tamsulosin group (84.1% vs. 61.0%, p=0.017). Although the occurrence of side effects was higher with tadalafil, this difference was not significant (p=0.099). There were no serious adverse effects. Tadalafil has a significantly higher stone expulsion rate than tamsulosin when used as a medical expulsive therapy for distal ureteral stones sized 5-10 mm. Both drugs are safe, effective, and well tolerated with minor side effects.

To characterize risk of hypotension requiring admission to hospital in middle aged and older men treated with tamsulosin for benign prostatic hyperplasia. Population based retrospective cohort study (between patient methodology) and self controlled case series (within patient methodology). Healthcare claims data from the IMS Lifelink database in the United States. Men aged 40-85 years with private US healthcare insurance entering the cohort at their first dispensing for tamsulosin or for a 5α reductase inhibitor (5ARI) between January 2001 and June 2011 after a minimum of six months' enrolment. Hypotension requiring admission to hospital. Cox proportional hazards models estimated rate ratios at time varying intervals during follow-up: weeks 1-4, 5-8, and 9-12 after tamsulosin initiation; weeks 1-4, 5-8, and 9-12 after restarting tamsulosin (after a four week gap); and maintenance tamsulosin treatment (remaining exposed person time). Covariates included age, calendar year, demographics, antihypertensive use, healthcare use, and a Charlson comorbidity score. A self controlled case series, having implicit control for time invariant covariates, was additionally conducted. Among 383,567 new users of study drugs (tamsulosin 297,596; 5ARI 85,971), 2562 admissions to hospital for severe hypotension were identified. The incidence for hypotension was higher for tamsulosin (42.4 events per 10,000 person years) than for 5ARIs (31.3 events per 10,000 person years) or all accrued person time (29.1 events per 10,000 person years). After tamsulosin initiation, the cohort analysis identified an increased rate of hypotension during weeks 1-4 (rate ratio 2.12 (95% confidence interval 1.29 to 3.04)) and 5-8 (1.51 (1.04 to 2.18)), and no significant increase at weeks 9-12. The rate ratio for hypotension also increased at weeks 1-4 (1.84 (1.46 to 2.33)) and 5-8 (1.85 (1.45 to 2.36)) after restarting tamsulosin, as did maintenance tamsulosin treatment (1.19 (1.07 to 1.32)).

Full Text Available This study was performed to investigate the effects of alfuzosin, doxazosin and tamsulosin in vitro on trigone smooth muscle of rabbit. In this study, fifteen rabbits weighing 2.5 - 3 kg were used. One strip in the shape of a trigone was prepared for each of the isolated bladders. Firstly, an initial tension of 1 g was placed on each segment, and we waited for equilibration by constantly bubbling with 95% O2 and 5% CO2. Next, the determination level of electrical stimulation which created submaximal contraction and effective dosage were found for trigone and they were determined by applying different concentrations of phenylephrine (10-8 M, 10-7 M, 10-6 M, 10-5 M, respectively. Firstly 10-8 M dosage of alfuzosin (10-8 M, 10-7 M, 10-6 M, 10-5 M was added, then we waited for 20 min. Then, an effective dosage of phenylephrine (10-5 M was added into the solution and we waited for 7 min again. After this process, electrical stimulation was applied for the contraction of the tissue. After stimulation, the tissue was washed twice every two minutes and rested; we waited until the tissue reached its starting stretching value. The same processes were performed for the other dosages of alfuzosin (10-7 M, 10-6 M, 10-5 M, doxazosin (10-7 M, 10-6 M, 10-5 M and tamsulosin (10-7 M, 10-6 M, 10-5 M, respectively. In conclusion, when we compared the amplitudes of the responses of all concentrations of doxazosin, alfuzosin and tamsulosin in the trigone smooth muscle with amplitude of a response of effective concentration of phenylephrine, it was determined that the prevention level of contractions occurred after tamsulosin hydrochloride was higher than after alfuzosin hydrochloride and doxazosin mesylate. With these results, we showed that alfuzosin, doxazosin and tamsulosin inhibited noradrenalin-based contractions in the rabbit trigone smooth muscle and this result can be used both for in vitro and in vivo future studies.

We evaluated the efficacy and safety of add-on treatment with a β3-adrenoceptor agonist (mirabegron) for overactive bladder symptoms remaining after α1-blocker (tamsulosin) treatment in men with benign prostatic obstruction. Patients with benign prostatic obstruction with urinary urgency at least once per week and a total OABSS of 3 or more points after 8 or more weeks of treatment with tamsulosin were enrolled in the study. They were randomly allocated to receive 0.2 mg tamsulosin daily or 0.2 mg tamsulosin and 50 mg mirabegron daily for 8 weeks. The primary end point was change in total OABSS. Safety assessments included change in post-void residual urine volume and adverse events. From January 2012 through September 2013 a total of 94 patients were randomized. Of these patients 76 completed the protocol treatment. In the full analysis set the change in total OABSS during the treatment period was significantly greater in the combination group than in the monotherapy group (-2.21 vs -0.87, p=0.012). The changes in scores for urinary urgency, daytime frequency, International Prostate Symptom Score storage symptom subscore and quality of life index at 8 weeks were significantly greater in the combination group. The change in post-void residual urine volume was significantly greater in the combination group. Although 6 patients experienced adverse events in the combination group, urinary retention was observed in only 1 patient. Combined tamsulosin and mirabegron treatment is effective and safe for patients with benign prostatic obstruction who have overactive bladder symptoms after tamsulosin monotherapy.

We assessed the effect of tamsulosin as an adjunctive therapy after shock wave lithotripsy for pediatric single renal pelvic stones. A total of 120 children with a unilateral single renal pelvic stone were included in a prospective randomized, controlled study. All children were randomized to 2 equal groups. Group 1 received tamsulosin (0.01 mg/kg once daily) as adjunctive therapy after shock wave lithotripsy in addition to paracetamol while group 2 received paracetamol only. Stone clearance was defined as no renal stone fragments or fragments less than 3 mm and no pelvicalyceal system dilatation. Our study included 69 boys and 51 girls with a median age of 3.5 years and a median stone size of 1.2 cm. There was no statistically significant difference between groups 1 and 2 in stone or patient criteria. Of the children 99 (82.5%) achieved stone clearance after the first session, including 50 in group 1 and 49 in group 2. All children in each group were cleared of stones after the second session. The overall complication rate was 14.2%. There was no statistically significant difference between single session stone clearance rates (p = 0.81) and complications rates (p = 0.432) in either group. On multivariate analysis using logistic regression smaller stone size (p = 0.016) and radiopaque stones (p = 0.019) were the only predictors of stone clearance at a single shock wave lithotripsy session. Tamsulosin therapy did not affect stone clearance (p = 0.649). Tamsulosin does not seem to improve renal stone clearance. Smaller and radiopaque renal stones have more chance of clearance after shock wave lithotripsy for pediatric single renal pelvic stones.

Storage symptoms are often undertreated in men with lower urinary tract symptoms (LUTS). To evaluate the combination of an antimuscarinic (solifenacin) with an α-blocker (tamsulosin) versus tamsulosin alone in the treatment of men with LUTS. A double-blind, 12-wk, phase 2 study in 937 men with LUTS (≥ 3 mo, total International Prostate Symptom Score [IPSS] ≥ 13, and maximum urinary flow rate 4.0-15.0 ml/s). Eight treatment groups: tamsulosin oral controlled absorption system (OCAS) 0.4 mg; solifenacin 3, 6, or 9 mg; solifenacin 3, 6 or 9 mg plus tamsulosin OCAS 0.4 mg; or placebo. The primary efficacy end point was change from baseline in total IPSS. Secondary end points included micturition diary and quality-of-life (QoL) parameters. Post hoc subgroup analyses were performed by severity of baseline storage symptoms, with statistical comparisons presented only for tamsulosin OCAS alone versus combination therapy, due to the small sample size of the solifenacin monotherapy and placebo subgroups. Combination therapy was associated with significant improvements in micturition frequency and voided volume versus tamsulosin OCAS alone in the total study population; improvements in total IPSS were not significant. Statistically significant improvements in urgency episodes, micturition frequency, total urgency score, voided volume, IPSS storage subscore, IPSS-QoL index, and Patient Perception of Bladder Condition were observed in a subpopulation of men with two or more urgency episodes per 24h (Patient Perception of Intensity of Urgency Scale grade 3 or 4) and eight or more micturitions per 24h at baseline (storage symptoms subgroup) with combination therapy versus tamsulosin OCAS alone (p ≤ 0.05 for the dose-response slope, all variables). Combination therapy was well tolerated, and adverse events were consistent with the safety profiles of both compounds. Solifenacin plus tamsulosin OCAS did not significantly improve IPSS in the total study population but offered

Indwelling double J ureteral stents are used routinely in the resolution of ureteral obstruction caused by different etiologies. Evaluation of urinary symptoms related to double-J stent, indicate that these affect 73-90% of patients. We conducted a prospective, randomized study, to evaluate the efficacy of tamsulosin, oxybutinin and combination therapy in improving the urinary symptoms. Patients who underwent ureteral stent placement after ureterolithotripsy (total 51), were randomized into three groups: Group I: Tamsulosin 0.4 mg. Once per day(17 patients), Group II: Oxybutinin 5 mg. once per day (17 patients), Group III: Tamsulosin+ oxybutynin once per day (17 patients). All the groups received the drugs for three weeks and completed a Spanish validated Ureteral Stent Symptom Questionnaire (USSQ) at day 7 and 21. Repeated measures ANOVA showed mean urinary symptom index score was 22.3 vs. 15.5 in group three (ptamsulosin group, the mean sexual score was 0.5 vs 1.5 (p=0.03). Among additional problems the mean was 7.2 vs 6.2 (p=0.03). No significant difference was noted among pain and general health index. No side effects were reported. Combination therapy with tamsulosin and oxybutynin improved irritative symptoms and work performance as well as sexual matters. Combination therapy should be considered for patients who complained of stent related symptoms.

The aim of this study was to define if tadalafil causes detrusor muscle impairment and to observe the effect of combination of tadalafil with tamsulosin on the lower urinary tract of rats with bladder outlet obstruction (BOO) induced by chronic nitric oxide deficiency. Thirty-one male rats were randomized to following groups: 1 - control; 2 - L-Nitroarginine methyl ester (L-NAME); 3 - Tamsulosin + L-NAME, 4 Tadalafil+L-NAME; and 5 - Tamsulosin + Tadalafil + L-NAME. At the end of the treatment period (30 days), all animals were submitted to urodynamic study. The administration of L-NAME increased the number of non-voiding contractions (NVC) (1.04 ± 0.22), volume threshold (VT) (1.86 ± 0.35), and micturition cycle (MC) (1.34 ± 0.11) compared with control (0.52 ± 0.06, 0.62 ± 0.06, and 0.67 ± 0.30), respectively. The administration of tamsulosin reduced the number of NVC (0.57 ± 0.42) and VT (0.76 ± 0.24 ) compared with L-NAME group. Co-treatment with tadalafil decreased the number of VT (0.85 ± 0.53) and MC (0.76 ± 0.22) compared with L-NAME group. The combination of tamsulosin with tadalafil improved the number of NVC (0.56 ± 0.18), VT (0.97 ± 0.52) and MC (0.68 ± 0.30) compared with L-NAME group. In rats with BOO induced by chronic nitric oxide deficiency, tadalafil did not cause impairment in detrusor muscle and seems to have an addictive effect to tamsulosin because the combination decreased non voiding contractions as well the number of micturition cycles.

Full Text Available Introduction: Naftopidil, approved initially in Japan, is an α1d-adrenergic receptor antagonist (α1-blocker used to treat lower urinary tract symptoms (LUTS due to benign prostatic hyperplasia (BPH. It is different from tamsulosin hydrochloride and silodosin, in that it has a higher affinity for the α1D-adrenergic receptor subtype than for the α1A subtype and has a superior efficacy to a placebo and comparable efficacy to other α1-blockers such as tamsulosin. The incidences of ejaculatory disorders and intraoperative floppy iris syndrome induced by naftopidil may also be lower than that for tamsulosin and silodosin, which have a high affinity for the α1A-adrenergic receptor subtype. However, it remains unknown if the efficacy and safety of naftopidil in Japanese men is applicable to Indian men having LUTS/BPH. Material and Methods: Two groups of 60 patients each, having LUTS due to BPH, were treated with tamsulosin 0.4 mg and Naftopidil 75 mg for three months. Ultrasonography (for prostate size, post-void residual volume, uroflowmetry, and the International Prostate Symptom Score (IPSS and Quality of Life (QOL score were recorded at the beginning of the study, and then at one and three months. Results: The prostate size, post-void residual volume, all the uroflowmetry variables, and the IPSS QOL scores showed a statistically significant improvement (P < 0.001 in both the groups. The improvement in the average flow rate and the QOL index was better in the naftopidil group on the intergroup comparison and was statistically significant (P < 0.001. C onclusion: Although the QOL life index was significantly better in the naftopidil group, overall both naftopidil and tamsulosin were found to be equally effective in the treatment of LUTS due to BPH.

To verify the efficacy and safety of tamsulosin 0.4 mg and tamsulosin 0.2 mg compared with those of placebo in patients with lower urinary tract symptoms (LUTS) associated with benign prostatic hyperplasia (BPH). A total of 494 patients from multiple centers participated in this double-blind, randomized, phase 3 trial. Eligible patients were randomly assigned to the tamsulosin 0.4 mg group, tamsulosin 0.2 mg group or placebo group. The International Prostate Symptom Score (IPSS), maximum flow rate (Qmax), post-void residual (PVR) urine volume, blood pressure, heart rate and adverse events were compared among the three groups at 4, 8 and 12 weeks. A total of 494 BPH patients were analyzed. There were no differences in the baseline characteristics among the three groups. After 12 weeks of treatment, total IPSS was improved in the 0.2 mg and 0.4 mg tamsulosin groups; however, the extent of improvement was greater in the 0.4 mg group than in the 0.2 mg group (0.4 mg: -9.59 vs. 0.2 mg: -5.61; least-squares mean difference [95% confidence interval]: -3.95 [-5.01, -2.89], p Tamsulosin 0.4 mg and 0.2 mg appear to be superior to placebo treatment, and tamsulosin 0.4 mg is more effective than 0.2 mg in terms of total IPSS improvement. Tamsulosin 0.4 mg has favorable efficacy and tolerability in Asian men with symptomatic BPH. ClinicalTrials.gov Identifier: NCT02390882.

To present a new grouping of male patients with lower urinary tract symptoms (LUTS) based on symptom patterns and clarify whether the therapeutic effect of α1-blocker differs among the groups. We performed secondary analysis of anonymous data from 4815 patients enrolled in a postmarketing surveillance study of tamsulosin in Japan. Data on 7 International Prostate Symptom Score (IPSS) items at the initial visit were used in the cluster analysis. IPSS and quality of life (QOL) scores before and after tamsulosin treatment for 12 weeks were assessed in each cluster. Partial correlation coefficients were also obtained for IPSS and QOL scores based on changes before and after treatment. Five symptom groups were identified by cluster analysis of IPSS. On their symptom profile, each cluster was labeled as minimal type (cluster 1), multiple severe type (cluster 2), weak stream type (cluster 3), storage type (cluster 4), and voiding type (cluster 5). Prevalence and the mean symptom score were significantly improved in almost all symptoms in all clusters by tamsulosin treatment. Nocturia and weak stream had the strongest effect on QOL in clusters 1, 2, and 4 and clusters 3 and 5, respectively. The study clarified that 5 characteristic symptom patterns exist by cluster analysis of IPSS in male patients with LUTS. Tamsulosin improved various symptoms and QOL in each symptom group. The study reports many male patients with LUTS being satisfied with monotherapy using tamsulosin and suggests the usefulness of α1-blockers as a drug of first choice. Copyright © 2015 Elsevier Inc.

Currently alpha1-adrenoceptor blockers (AB) are widely used as first-line therapy to improve lower urinary tract symptoms (LUTS) associated with benign prostatic hyperplasia (BPH). We compared the efficacy and safety profile of tamsulosin, alfuzosin and silodosin in LUTS due to BPH. Consecutive consenting male patients (N = 269) undergoing medical management of BPH with AB from February 2012 to October 2015 were enrolled. Patients were randomized to a 0.4 mg tamsulosin (group T), 10 mg alfuzosin (group A) or a 8 mg silodosin (group S) by double-blind randomization. All patients were assessed for improvements and post-void residual urine (PVR) and for adverse drug events (ADE). IPSS showed significant improvement in Group S at the first week (11.7 ±4.18, p = 0.027) and at 3 months (7.97 ±3.84, p = 0.020). QOL showed significant improvement at 1 (2.2 ±0.76, p = 0.020), 4 (1.47 ±0.63, p BPH and objectively improves maximum flow rate. However, silodosin has more adverse events when compared to tamsulosin and alfuzosin.

Efficacy and safety of a fixed-dose combination of dutasteride and tamsulosin treatment (Duodart(®) ) compared with watchful waiting with initiation of tamsulosin therapy if symptoms do not improve, both provided with lifestyle advice, in the management of treatment-naïve men with moderately symptomatic benign prostatic hyperplasia: 2-year CONDUCT study results.

To investigate whether a fixed-dose combination (FDC) of 0.5 mg dutasteride and 0.4 mg tamsulosin is more effective than watchful waiting with protocol-defined initiation of tamsulosin therapy if symptoms did not improve (WW-All) in treatment-naïve men with moderately symptomatic benign prostatic hyperplasia (BPH) at risk of progression. This was a multicentre, randomised, open-label, parallel-group study (NCT01294592) in 742 men with an International Prostate Symptom Score (IPSS) of 8-19, prostate volume ≥30 mL and total serum PSA level of ≥1.5 ng/mL. Patients were randomised to FDC (369 patients) or WW-All (373) and followed for 24 months. All patients were given lifestyle advice. The primary endpoint was symptomatic improvement from baseline to 24 months, measured by the IPSS. Secondary outcomes included BPH clinical progression, impact on quality of life (QoL), and safety. The change in IPSS at 24 months was significantly greater for FDC than WW-All (-5.4 vs -3.6 points, P tamsulosin. FDC therapy with dutasteride and tamsulosin, plus lifestyle advice, resulted in rapid and sustained improvements in men with moderate BPH symptoms at risk of progression with significantly greater symptom and QoL improvements and a significantly reduced risk of BPH progression compared with WW plus initiation of tamsulosin as per protocol. © 2015 The Authors.

Phytotherapy has been used to treat patients with lower urinary tract symptoms (LUTS). We evaluated the efficacy and tolerability of combination therapy between Serenoa Repens (SeR), Lycopene (Ly), and Selenium (Se) + tamsulosin versus single therapies. PROCOMB trial (ISRCTN78639965) was a randomized double-blinded, double-dummy multicenter study of 225 patients between 55 and 80 years old, PSA ≤ 4 ng/ml, IPSS ≥12, prostate volume ≤60 cc, Qmax ≤15 ml/sec, postvoid residual urine (PVR) tamsulosin 0.4 mg), group C (SeR-Se-Ly + tamsulosin 0.4 mg). The primary endpoints of the study were the reduction of IPSS, PVR, and increase of Qmax in group C versus monotherapy groups. The decrease for combination therapy was significantly greater versus group A (P tamsulosin therapy is more effective than single therapies in improving IPSS and increasing Qmax in patients with LUTS. © 2014 Wiley Periodicals, Inc.

A strong association exists between the use of tamsulosin and the occurance of intraoperative floppy iris syndrome. Several methods were advocated to overcome the progressive intraopertive miosis.Our purpose was to investigate the effect of a mydriatic-cocktail soaked cellulose sponge on perioperative pupil diameter in tamsulosin-treated patients undergoing elective cataract surgery. Patients using tamsulosin were dilated either with mydriatic-cocktail soaked sponge (group 1) or with conventional eyedrop regimen (group 2). Control patients not taking any α1 adrenergic receptor inhibtors were also dilated with mydriatic sponge (group 3).In all groups oxybuprocain 0.4%, cocain 4%, tropicamide 1%, phenylephrine 10%, diclophenac 0.1% along with chloramphenicol 0.5% were used preoperatively.Pupil diameter (mm) was measured preoperatively, after nucleus delivery, and before IOL implantation. Adverse effects associated with the use of sponge, minor and major intraoperative complications, the use of iris retractors and operation time were recorded.Differences in general between groups were analyzed with a one way analysis of variance (ANOVA); differences between groups in proportions were assessed by Fisher's exact test. Mean pupil diameter (mm) was preopertively: 7.52 ± 1.21, 7.30 ± 1.55 and 7.99 ± 0.96 (ANOVA: p = 0.079); after nucleus delivery: 6 ± 1.20, 6.29 ± 1.12 and 6.52 ± 0.81 (ANOVA: p = 0.123); before IOL implantation: 5.46 ± 1.06, 5.83 ± 1.09 and 6.17 ± 0.89 (ANOVA: p = 0.0291).No adverse effect related to sponge use was detected. Frequency of minor complications, and iris hook use was similar in the two tamsulosin treated group. Operation time did not differ significantly in the three groups. We have found that using a mydriatic cocktail-soaked wick - an alternative way to achieve intraoperative mydriasis for cataract surgery - was as effective and safe as the conventional repeated eyedrops regiment for tamsulosin treated patients.

The objective of the present study was to determine the optimum composition for sustained-release of tamsulosin hydrochloride from microparticles intended for orally disintegrating tablets. Microparticles were prepared from an aqueous ethylcellulose dispersion (Aquacoa®), and an aqueous copolymer based on ethyl acrylate and methyl methacrylate dispersion (Eudragit®) NE30D), with microcrystalline cellulose as core particles with a fluidized bed coating process. Prepared microparticles were about 200 μm diameter and spherical. The microparticles were evaluated for in vitro drug release and in vivo absorption to assess bioequivalence in a commercial product, Harnal® pellets. The optimum ratio of Aquacoat® and Eudragit® NE30D in the matrix was 9:1. We observed similar drug release profiles in microparticles and Harnal® pellets. Higuchi model analysis of the in vitro drug release from microparticles was linear up to 80% release, typical of Fickian diffusion sustained-release profile. The in vivo absorption properties from microparticles were comparable to Harnal® pellets, and there was a linear relationship between in vitro drug release and in vivo drug release. In conclusion, this development produces microparticles in single-step coating, that provided a sustained-release of tamsulosin hydrochloride comparable to Harnal® pellets.

We present a prospective randomized study to compare the efficacy of tamsulosin and silodosin in patients suffering from acute urinary retention caused by benign prostatic hyperplasia, planned for trial without catheter. Patients with acute urinary retention secondary to benign prostatic hyperplasia (total 160) were catheterized and randomized into two groups: Group A: tamsulosin 0.4 mg (80 patients) and Group B: silodosin 8 mg (80 patients). After three days, the catheter was removed, and patients were put on trial without catheter. Patients with a successful trial without catheter were followed up after two weeks and one month, taking into account the international prostate symptom score (IPSS), post void residual volume (PVR), and peak flow rate (PFR). Statistical analysis of the data was performed. Both group A (tamsulosin) and group B (silodosin) had similar results of trial without catheter (group A: 67.50%, group: B 60%). In follow up, three patients in group A and four patients in group B had retention of urine, requiring recatheterization. These patients were withdrawn from the study. No significant differences were present between group A and group B patients in regard with IPSS, PVR and PFR measured at the time of successful trial without catheter and during follow up at two weeks and one month. Efficacy for trial without catheter of tamsulosin was slightly higher than silodosin, but comparable. No statistical difference between tamsulosin & silodosin treated groups were found in regard with IPSS, PVR and PFR.

This study aimed at comparing the success rates of silodosin to the most commonly used for medical expulsive therapy (MET) tamsulosin for the management of ureteral stones. A systematic review using the search string: "silodosin AND (ston* OR calcu* OR expul*)" was conducted on Pubmed, SCOPUS, Web of Science, Cochrane Central Register. The Primary endpoint was the stone expulsion rate. Secondary endpoint was the time to stone expulsion. Two authors independently screened the studies depending on inclusion and exclusion criteria. Meta-analysis and forest-plot figures were calculated with the software Review Manager (RevMan 5.3.5). Variations were evaluated with the χ 2 statistical method and heterogeneity with I 2 index. After screening of 39 publications obtained by the initial search, three randomized controlled trials were eligible to be included in the meta-analysis. 407 patients were pooled. Favorable results were observed for silodosin in terms of stone expulsion rates with a risk ratio of 1.33 (95 % CI 1.17-1.50) (I 2  = 0 %). Similarly, faster stone expulsion times were observed with silodosin when compared with tamsulosin. Mean difference -2.49 (95 % CI -3.40 to 1.58) (I 2  = 89 %). This meta-analysis showed significantly higher stone expulsion rates and faster expulsion times in favor of silodosin when compared to tamsulosin.

Full Text Available Background: Ureteral double J stent are routinely applied for urologic patients although stent-related symptoms are common. Several attempts have been reported to minimize these symptoms. Objective: To compare Tolterodine, Tamsulosin, and placebo effects on double J stent–related symptoms. Material and method: In all, 125 patients (82 males and 43 females with double J stent were randomly divided into three groups (group 1, n: 42, group2, n: 40 and group 3, n: 43. Each patient randomly received one pack of drug in different colors by a nurse unaware of the content to take Tamsulosin 0.4 mg before sleep (MODALUSINE, Tolterodine 2 mg twice a day or placebo once daily (capsules filled with starch: group 1 received placebo, group 2 Tamsulosin and group 3 Tolterodine for 1 month in a double-blind manner. Ureteral stent-related morbidity indices which analyzed include urinary symptom, pain, general health, quality of work and sex scores. All of indices measured by Ureteral Symptom Score Questionnaire for first and fourth weeks after drug consumption and the first week after double J stent removal (labeled as w1, w4, and w5, respectively. Result: The mean age was 44.8 years (range: 15–83 years. There was no statistically significant difference in background characteristics between groups (p value > 0.05. The most important and statistically significant results were Tolterodine-reduced urinary symptom score (p value = 0.001 and improved general health score (p value = 0.007 of the fourth week. The pain score in groups of Tamsulosin and Tolterodine significantly reduced between weeks 4 and 1 and 5 and 1 (both with the p value < 0.05, but in other indices, there was no significant difference between them. Conclusion: According to our results, we suggest Tolterodine to minimize stent-related urinary symptom and improve general health in patients with double J stent.

To study the effectiveness and safety of combined standard-dosed Solifenacin and Trospium for management of symptoms of overactive bladder (OAB) in elderly patients after the treatment with Tamsulosin. A total of 417 men over 50 years of age (average age 57.9 (8.3)) with diagnosed prostatic obstruction (score 8-19 according to I-PSS), who had not taken Tamsulosin before, were enrolled in the study. I-PSS questionnaire (from 8 to 19 - moderate) and Awareness Tool questionnaire for evaluating OAB symptoms (total score for OAB symptoms over 8) were used at the beginning and at the end of the observation. Also, urodynamic parameters were examined. Percentage of patients with prevalent symptoms of obstruction of urethra decreases after the treatment with Tamsulosin and then rises again (36.2%), but absolute number of patients remains smaller than initial data. Percentage of patients with relative prevalence of symptoms of overactive bladder slightly increases against administration of Tamsulosin and reaches initial values at the time of administration of anti-muscarinic drugs with absolute decrease in number of such patients. Combination of Trospium and Solifenacin is an effective way to manage residual symptoms of hyperactive bladder during treatment of early obstruction of urinary bladder.

The role of α-blockers after shockwave lithotripsy (SWL) is controversial. The aim of our study was to evaluate the effect of tamsulosin and silodosin after SWL for kidney stones. From 2012 onward, a consecutive series of patients undergoing SWL were prospectively enrolled and randomized by closed envelopes in three groups receiving tamsulosin 0.4 mg (A), silodosin 8 mg (B), and placebo (C) daily for 21 days after SWL. Anthropometrics, stone size, and location were recorded before SWL. Visual analogue scale (VAS) score was collected at 6, 12, and 24 hours after treatment to evaluate patients' discomfort. Stone-free rate was assessed 1 and 3 weeks postoperatively. Complications and medical treatment-related adverse events (AEs) were recorded. Differences in VAS score, stone-free rate, and complications were compared among the groups. Overall, 60 patients were enrolled. Mean stone sizes were 10.28 ± 2.46 mm, 10.45 ± 1.73 mm, and 9.23 ± 2.04 mm in groups A, B, and C, respectively (p = 0.474). There was no significant difference between the three groups with regard to stone location. Comparable energy was used to treat patients from the three groups. The overall 3-week stone-free rate was 53%: 58% in the tamsulosin group, 47% in the silodosin group, and 55% in the placebo group (p = 0.399). No significant differences were observed in the VAS scores reported by the groups at 6 hours (p = 1.254), 12 hours (p = 0.075), and 24 hours (p = 0.490). Overall, 12 complications were reported: 11 patients (7 in group C and 4 in group B) needed analgesics for colic, and 1 patient (group B) was surgically treated for Steinstrasse. Tamsulosin was superior to placebo (p = 0.008) and silodosin (p = 0.021) in preventing complications; no difference between silodosin and placebo (p = 0.629) was noted. Tamsulosin and silodosin are ineffective in increasing stone-free rate as well as early patients' discomfort after extracorporeal

To compare the efficacy of the doxazosin gastrointestinal therapeutic system (doxazosin-GITS) 4 mg and tamsulosin 0.2 mg on nocturia in Chinese men with lower urinary tract symptoms (LUTS) suggestive of benign prostatic hyperplasia (BPH). Data were analyzed from a prospective, multicenter, randomized, open, parallel study of Chinese men aged 50-84 years with LUTS/BPH. Two hundred patients were randomized to receive daily treatment with 4 mg doxazosin-GITS (n=100) or 0.2 mg tamsulosin (n=100) for 8 weeks. Nocturia was assessed by question 7 of the International Prostate Symptom Score (IPSS-question 7) and a frequency-volume chart (FVC) at weeks 4 and 8. Self-reported quality of sleep and quality of life by the last question of the IPSS questionnaire were also evaluated. A total of 189 patients (94 receiving doxazosin-GITS, 95 tamsulosin) completed the study. The reduction from baseline in mean nocturia was greater with doxazosin-GITS than tamsulosin by the FVC (1.7 vs 1.3 at week 4; 2.1 vs 1.7 at week 8, both P=.001) and by the IPSS-question 7 (1.5 vs 1.1 at 4 weeks, P=.001; 2.0 vs 1.6 at 8 weeks, Psleep was significantly more with doxazosin-GITS than tamsulosin (43.6% vs 27.4% at 4 weeks, P=.020; 81.9% vs 67.4% at 8 weeks, P=.022), and quality of life was better with doxazosin-GITS (2.5 vs 2.8 at 4 weeks, P=.001; 2.1 vs 2.5 at 8 weeks, P<.001). In Chinese patients with LUTS/BPH, doxazosin-GITS is slightly better than tamsulosin in reducing the frequency of nocturia. Copyright © 2011 Elsevier Inc. All rights reserved.

Background Benign prostatic hyperplasia (BPH), a common disease in men over age 50 years, often causes bladder outlet obstruction and lower urinary tract symptoms (LUTS). Alpha blockers in combination with muscarinic receptor antagonists may have the potential to improve symptoms. This study aimed to assess the efficacy and safety of doxazosin or tamsulosin combined with tolterodine extend release (ER) in patients with BPH and LUTS. Material/Methods In a prospective, randomized, open-label study (ChiCTR-IPR-15005763), 220 consecutive men with BPH and LUTS were allocated to receive doxazosin 4 mg and tolterodine ER 4 mg per day (doxazosin group) or tamsulosin 0.2 mg and tolterodine ER 4 mg per day (tamsulosin group). Treatment lasted 12 weeks. The primary endpoint was the international prostatic symptom score (IPSS). Secondary endpoints were quality of life (QoL) and maximum flow rate (Qmax), which were evaluated at 0, 6, and 12 weeks, and urodynamic parameters assessed at 0 and 12 weeks. Results A total of 192 patients completed the trial. Baseline measurements showed no differences between the groups. After 6 weeks, IPSS improved in both groups and QoL was significantly better in the doxazosin group (P=0.01). After 12 weeks, Qmax, IPSS, QoL, intravesical pressure (Pves), and bladder compliance (BC) in the doxazosin group were significantly better than in the tamsulosin group (P=0.03, P<0.001, P<0.001, P=0.027, and P=0.044, respectively). Conclusions Administration of alpha blockers combined with muscarinic receptor blocker for 12 weeks improved LUTS in men with BPH. PMID:27260129

This study was undertaken to determine the impact on ejaculatory function of tamsulosin (0.2 mg) given once daily (OD) for 12 weeks and to identify risk factors for ejaculatory dysfunction in patients undergoing this treatment. Males with an International Prostatic Symptom Score (IPSS) ≥8 were enrolled in this study. All participants completed questionnaires, including the IPSS and the Male Sexual Health Questionnaire (MSHQ), and serum prostate-specific antigen, transrectal ultrasound and uroflowmetry with post-void residual were measured. After initiating 0.2 mg OD tamsulosin, patients were re-evaluated on the fourth and twelfth weeks of medication. The chi-squared test, the independent t-test and one-way ANOVA were used to compare means. Binary logistic regression analysis was used to calculate the odds ratio for all risk factors. A total of 177 men constituted the study cohort. No significant difference was observed between baseline and follow-up for the erectile function, ejaculatory function, satisfaction, sexual activity and desire domains (EFD, EjFD, SDA and ADD) or for erectile or ejaculatory bother mean scores. After 12 weeks, the overall incidence of ejaculatory dysfunction (EjD) was 13.4%. Incidences of the seven different types of EjD (decreased frequency, delay, dryness, decreased strength/force, decreased volume, decreased pleasure and pain at ejaculation) were 2.4%, 3.1%, 3.9%, 3.9%, 6.3%, 7.1% and 3.1%, respectively. Baseline EjFD scores were higher for IPSS responders than for non-responders (26.09 vs. 24.06, P=0.03). An EjFD score reduction was more frequent in IPSS responders. The incidence of EjD was small, but not negligible and was more frequent in patients with less lower urinary tract symptoms, a smaller prostate, higher baseline MSHQ totals and higher EjFD scores.

To study the cognitive functions and health-related quality of life (HRQoL) in individuals taking a combination of tamsulosin and solifenacin in a higher dosage. All patients (n = 262) were assigned to group A (N = 93, tamsulosin 0.4 mg + solifenacin 10 mg per day), group B (N = 83, tamsulosin 0.4 mg + solifenacin 20 mg), and control group C (N = 86; tamsulosin 0.4 mg + placebo). The lower urinary tract (LUT) condition was assessed on the scales International Prostate Symptom Score, Over Active Bladder Awareness Tool and uroflowmetry. The state of cognitive status was assessed on the scales Mini-mental State Examination, Controlled Oral Word Association Test, Wechsler Adult Intelligence Scale-Revised, Wechsler III, Color Trails Test, California Verbal Learning Test.

Full Text Available BackgroundIncreasingly, prophylactic mastectomy has been evaluated as a treatment of breast cancer. Hereditary breast cancer now accounts for approximately 5%–10% of all cases of breast cancer, meaning that the widespread implementation of prophylactic mastectomy may significantly reduce the occurrence of breast cancer. However, prophylactic mastectomy is rarely performed in Korea. Therefore, in this study, we assessed Koreans' attitudes toward and awareness of preventive mastectomy.MethodsThis was a prospective study of a cohort of patients attending outpatient clinics and their relatives. Data were collected using self-administered questionnaires assessing sex, age, educational level, knowledge of breast cancer, understanding of prophylactic mastectomy, attitudes toward prophylactic mastectomy, and reasons for choosing prophylactic mastectomy.ResultsSixty-five patients were included. Most patients (36.9% were between 40 and 49 years of age and 58.4% were college graduates. Only six respondents (9% understood prophylactic mastectomy, and 17 respondents (27% stated that they would agree to undergo prophylactic mastectomy if necessary. Reasons given for refusing prophylactic mastectomy included aesthetic concerns (38%, the perception that it would not cure the disease (26%, possible surgical complications (24%, and financial cost (6%.ConclusionsIn this study, most of the respondents showed a poor knowledge of prophylactic mastectomy. Ultimately, it will be necessary to establish medical guidelines for patients with a high risk of breast cancer, with the objective of providing accurate information and proper treatment at hospitals.

Solifenacin/tamsulosin fixed-dose combination therapy to treat lower urinary tract symptoms in patients with benign prostatic hyperplasia

Full Text Available Konstantinos Dimitropoulos, Stavros Gravas Department of Urology, Faculty of Medicine, School of Health Sciences, University of Thessaly, Larissa, Greece Abstract: Treatment of male lower urinary tract symptoms (LUTS has traditionally focused on the management of benign prostatic obstruction, but the contribution of bladder dysfunction has been recently recognized. Therefore, it is well understood that LUTS have multifactorial etiology and often occur in clusters and not in isolation. Voiding LUTS are highly prevalent in men, but storage LUTS have been proved to be more bothersome. α1-Blockers are the most widely used pharmacologic agents for the treatment of symptoms relating to benign prostatic enlargement due to benign prostatic hyperplasia (BPH, while antimuscarinics are the drug class of choice for overactive bladder symptoms. A combination of the two drug classes would be a reasonable approach to treat men with both storage and voiding symptoms, and several short-term studies have proved the efficacy and safety of different combinations with an α1-blocker and an antimuscarinic. Following previous studies on the separate administration of solifenacin and tamsulosin, a fixed-dose combination tablet of tamsulosin oral controlled absorption system (OCAS 0.4 mg and solifenacin succinate 6 mg has been recently introduced, and the current review evaluates the available data on the use of this fixed-dose combination in the treatment of LUTS in men with BPH.

To examine, using post hoc analysis, the influence of baseline variables on changes in international prostate symptom score (IPSS), maximum urinary flow rate (Qmax ) and IPSS quality of life (QoL) in patients with moderate-to-severe lower urinary tract symptoms (LUTS) due to benign prostatic hyperplasia (BPH) treated with either the α-blocker tamsulosin or the dual 5-alpha reductase inhibitor dutasteride, alone or in combination, as part of the 4-year Combination of Avodart and Tamsulosin (CombAT) study. CombAT was a 4-year, multicentre, randomized, double-blind, parallel-group study in 4844 men ≥50 years of age with a clinical diagnosis of BPH by medical history and physical examination, an IPSS ≥12 points, prostate volume (PV) ≥30 mL, total serum PSA level ≥1.5 ng/mL, and Qmax >5 mL/s and ≤15 mL/s with a minimum voided volume ≥125 mL. Eligible subjects were randomized to receive oral daily tamsulosin, 0.4 mg; dutasteride, 0.5 mg; or a combination of both. Baseline variable subgroups analysed were as follows: PV (30 to tamsulosin were performed from the general linear model with statistical significance defined as P ≤ 0.01. Combination therapy resulted in a significantly greater improvement from baseline IPSS at 48 months vs tamsulosin monotherapy across all baseline subgroups. The benefit of combination therapy over dutasteride was confined to groups with lower baseline PV (tamsulosin but not dutasteride monotherapy. Qmax improvement appeared to increase with PV and PSA level in combination therapy subjects. The proportion of subjects with an IPSS QoL ≤2 (at least mostly satisfied) at 48 months was significantly higher with combination therapy than with dutasteride for subgroups with PV 40-60 mL and PSA level tamsulosin for all PSA subgroups and PV subgroups ≥40 mL. CombAT data support the use of long-term combination therapy with dutasteride and tamsulosin in patients considered at risk for progression of BPH, as determined

To compare the efficacy and safety of single half-dose silodosin and single full-dose tamsulosin in Japanese men with lower urinary tract symptoms secondary to benign prostatic hyperplasia (LUTS/BPH). Japanese men aged ≥50 years with LUTS/BPH and an International Prostate Symptom Score (IPSS) of ≥8 were enrolled in the randomized crossover study and divided into silodosin-preceding (S-T) and tamsulosin-preceding (T-S) groups. The S-T group received 4 mg silodosin once daily for 4 weeks followed by 0.2 mg tamsulosin once daily for 4 weeks. The T-S group received the reverse treatment sequence. A washout period prior to drug crossover was not included. Subjective and objective efficacy parameters including IPSS, quality of life (QOL) index, uroflowmetry, and safety were compared between the two groups. Thirty of 34 men (S-T group n = 16; T-S group n = 14) completed the study. Both drugs significantly improved all IPSS items and QOL index in the first treatment period. Subjective improvement in nocturia by silodosin was observed in both the first and crossover treatment periods. Objective improvement in maximum flow rate by silodosin was only observed in the first treatment period. Adverse events occurred more frequently with silodosin than with tamsulosin; however, none of the adverse events required treatment discontinuation. Ejaculation disorders occurred in three participants (10%) and were associated with silodosin use. Single half-dose silodosin has a similar efficacy to full-dose tamsulosin in Japanese men with LUTS/BPH and thus, may represent an effective, safe, and affordable treatment option. © 2015 Wiley Publishing Asia Pty Ltd.

Benign prostatic hyperplasia (BPH) is a frequent cause of lower urinary symptoms, with a prevalence of 50% by the sixth decade of life. Hyperplasia of stromal and epithelial prostatic elements that surround the urethra cause lower urinary tract symptoms (LUTS), urinary tract infection and acute urinary retention. Medical treatments of symptomatic BPH include; 1) the 5α-reductase inhibitors, 2) the α1-adrenergic antagonists, and 3) the combination of a 5α-reductase inhibitor and a α1-adrenergic antagonist. Selective α1-adrenergic antagonists relax the smooth muscle of the prostate and bladder neck without affecting the detrussor muscle of the bladder wall, thus decreasing the resistance to urine flow without compromising bladder contractility. Clinical trials have shown that α1-adrenergic antagonists decrease LUTS and increase urinary flow rates in men with symptomatic BPH, but do not reduce the long-term risk of urinary retention or need for surgical intervention. Inhibitors of 5α-reductase decrease production of dihydrotestosterone within the prostate resulting in decreased prostate volumes, increased peak urinary flow rates, improvement of symptoms, and decreased risk of acute urinary retention and need for surgical intervention. Interim results of the ongoing Combination of Avodart and Tamsulosin (CombAt) study have shown combination therapy with the 5α-reductase inhibitor dutasteride and the α1-adrenergic antagonist tamsulosin offer significant improvements from baseline compared with either drug alone.

In Asian countries, low-dose tamsulosin (0.2 mg) is used widely but this dose has been less popular than 0.4 mg tamsulosin or other types of alpha blockers. The aim of this study was to investigate the efficacy and safety of low-dose tamsulosin by systematic review and meta-analysis. We conducted a meta-analysis of improvements of lower urinary tract symptoms using International Prostate Symptom Score (IPSS), maximal urinary flow rate (Qmax), post-voided residual volume (PVR), and quality of life (QOL). Relevant studies were found using MEDLINE, Embase, and the Cochrane library. Final inclusion was determined by randomized controlled trials (RCT) and performance of IPSS. A total of fourteen studies were included, with a total sample size of 2147 subjects (1044 experimental and 1103 controls). Study durations ranged from 4 to 52 weeks. The mean change of IPSS improvement from baseline for tamsulosin was -7.18 (95% CI: -7.83, -6.54). The mean change of QOL improvement from baseline was -1.34 (95% CI: -1.46, -1.22). The overall Qmax improvement from baseline was 2.32 ml/sec (95% CI: 1.95, 2.70). The mean change of PVR improvement from baseline was -11.12 ml (95% CI: -17.61, -4.64). Regarding safety, four studies did not report any adverse events while others reported that adverse events were all tolerated. Although this study did not consider placebo effect and has high IPSS baseline scores, this study clarifies that low-dose tamsulosin has generally positive effect and safety in treatment of LUTS and could be a suitable option as an initial treatment, especially for patients with low body mass index, as is typical of Asian people.

Objective: To determine the effect of Tamsulosin, as adjunctive medical therapy after Extracorporeal Shock Wave Lithotripsy for renal stones on rate of stone clearance, clearance time, pain intensity during stone clearance, steinstrasse formation and auxiliary surgical intervention required. Method: A prospective randomized controlled study was carried out in 120 patients who underwent ESWL for renal stones of 0.5-2.0 cm. They were randomized into study and control group in which Tamsulosin 0.4mg/day was given in former as an adjunctive medical therapy. All patients underwent ESWL every 2 weeks until complete stone clearance for 8 weeks. The parameters assessed were stone clearance, clearance time, pain intensity and effect on steinstrasse. Results: Of the 120 patients 60 were in each group. The stone clearance rate was greater in study than in control group, 58(96.7%) vs. 48(80%) respectively, (p<0.004). The mean stone clearance time was observed earlier in study group as compared to control group with significant statistical difference in stone size between 0.6-1.5 cm. The mean intensity of pain patients experienced according to Visual analogue scale (VAS) was significantly less in study group (p<0.002). The rate of steinstrasse formation was observed to be higher in control than in study group 15(25%) vs 6(10%) respectively(p<0.003), while its spontaneous clearance was higher in study group than in control group 83.3% vs 33.3% (p<0.03). Conclusion: Tamsulosin significantly increases stone clearance after shock wave lithotripsy for renal stones. It also appeared to facilitate earlier stone clearance, reduces severity of pain, reduces the incidence of steinstrasse formation and tends to facilitate its spontaneous clearance. (author)

The prophylactic administration of antibiotics to prevent infection and the prophylactic administration of anticonvulsants to prevent first seizure episodes are common practice in neurosurgery. If prophylactic medication therapy is not indicated, the patient not only incurs the discomfort and the inconvenience resulting from drug treatment but is also unnecessarily exposed to adverse drug reactions, and incurs extra costs. The main situations in which prophylactic anticonvulsants and antibiotics are used are described and those situations we found controversial in the literature and lack further investigation are identified: anticonvulsants for preventing seizures in patients with chronic subdural hematomas, antiepileptic drugs for preventing seizures in those suffering from brain tumors, antibiotic prophylaxis for preventing meningitis in patients with basilar skull fractures, and antibiotic prophylaxis for the surgical introduction of intracranial ventricular shunts.In the following we present systematic reviews of the literature in accordance with the standard protocol of The Cochrane Collaboration to evaluate the effectiveness of the use of these prophylactic medications in the situations mentioned. Our goal was to efficiently integrate valid information and provide a basis for rational decision-making.

This prospective study evaluated the efficacy and safety of a new formulation, Tamsulosin OCAS® (Oral Controlled Absorption System, for LUTS associated with BPH in Thai patients. MATERIALS AND METHODS: Fifty one patients over 40 years old with complaints of LUTS associated with BPH were recruited. Patients received an 8 week course of once daily 0.4 mg tamsulosin OCAS®, and were followed up at 2 (visit 3, 4 (visit 4 and 8 (visit 5 weeks post-treatment. At each visit, patients were assessed using the International Prostate Symptom Score (IPSS, Nocturia Quality of Life (N-QoL Questionnaire, QoL Assessment Index (IPSS-QoL, and International Index of Erectile Function (IIEF. The primary outcome was efficacy of Tamsulosin. The secondary outcomes included change in the mean number of nocturia episodes, hours of undisturbed sleep (HUS and uroflowmetry measurements. RESULTS: Total IPSS significantly decreased at week 8 from baseline (from 19.52 to 6.08; p < 0.001. Similarly, the voiding and storage subscores of IPSS also continued to improve significantly starting from the second and third visits, respectively (p < 0.001 versus baseline. The IPSS-QoL and N-QoL scores significantly improved at visit 3 through end of study. In addition, we observed significant nocturia and HUS improvement in their last clinic visit. Uroflowmetry parameters, Qmax and Qave, improved significantly at 3rd clinic visit . Three patients experienced mild dizziness. CONCLUSION: Tamsulosin OCAS® treatment led to significant improvements in LUTS, HUS and QoL in Thai patients with bladder outlet obstruction from BPH with few side effects.

Prophylactic digoxin is widely used in patients undergoing pulmonary surgery to prevent or control cardiac arrhythmias, but whether it is helpful or not is uncertain. An open, controlled randomised prospective clinical study of 111 patients was undertaken to compare the incidence of cardiac arrhythmias in the 58 patients who received preoperative digoxin and the 53 who did not. Cardiac arrhythmia occurred in half (29/58) of those given prophylactic digoxin and in 36% (19/53) of those who were not. The overall incidence of arrhythmia was 43%, with no statistically significant difference between the groups. Cardiac arrhythmias remain an important complication of pulmonary surgery and the incidence is not reduced by prophylactic digoxin.

Introduction: Renal stones are common disorders that affect approximately 5% to 10% of the population and the incidence of renal stones is rising. Treatment of ureteral stones is an important part of urologists and minimally invasive procedures such as ESWL and ureteroscopy effectiveness has been proven in various studies. However, these methods are not completely safe and are expensive and can be complicated. Purpose of this study is to evaluate the effectiveness of tamsulosin in the medical treatment of distal ureteral stones. Patients and methods: A total of 96 patients with distal ureteral stones or UVj are randomly divided into two study group (50 patients) and control group (46 patients). Patients in the control group allowed to freely consuming fluids (hydration) and indomethacin 100 mg PRN. Study group in addition to indomethacin and daily analgesic 0.4 mg tamsulosin was administered. All subjects in terms of analgesic dose, duration of expulsion and expulsion were studied. Results: Spontaneous expulsion of stone was occurred in 62.5% (30 patients out of 46) of control group patients and 82% (41 patients out of 50) that there was no significant difference (P>0.05). Average time to fix the stone in control group 4.7±8.03 days (range 2 to 28 days) and in the study group, 3.7±5.70 days (range 1 to 23 days) is significantly different (P>0.05). The average amount of analgesic consumption in the control group was 2.3±4.31and in the study group was 1.48±2.15 that showed significant differences (Ptamsulosin to conservative treatment of distal ureteral stones in the distal ureteral stone expulsion showed no significant difference between the two groups, but the reduction in the duration of expulsion, reduce pain and reduce the need for analgesic has been beneficial.

The past decade has seen an increasing prevalence of prophylactic mastectomy with decreasing ages of patients treated for breast cancer. Data are limited on the fiscal impacts of contralateral prophylactic mastectomy trends, and no study has compared bilateral prophylactic mastectomy with reconstruction to surveillance in high-risk patients. Lifetime third-party payer costs over 30 years were estimated with 2013 Medicare reimbursement rates. Costs were estimated for patients choosing contralateral or bilateral prophylactic mastectomy versus surveillance, with immediate reconstructions using a single-stage implant, tissue expander, or perforator-based free flap approach. Published cancer incidence rates predicted the percentage of surveillance patients that would require mastectomies. Sensitivity analyses were conducted that varied cost growth, discount rate, cancer incidence rate, and other variables. Lifetime costs and present values (3 percent discount rate) were estimated. Lifetime prophylactic mastectomy costs were lower than surveillance costs, $1292 to $1993 lower for contralateral prophylactic mastectomy and $15,668 to $21,342 lower for bilateral prophylactic mastectomy, depending on the reconstruction. Present value estimates were slightly higher for contralateral prophylactic mastectomy over contralateral surveillance but still cost saving for bilateral prophylactic mastectomy compared with bilateral surveillance. Present value estimates are also cost saving for contralateral prophylactic mastectomy when the modeled contralateral breast cancer incidence rate is increased to at least 0.6 percent per year. These findings are consistent with contralateral and bilateral prophylactic mastectomy being cost saving in many scenarios, regardless of the reconstructive option chosen. They suggest that physicians and patients should continue to receive flexibility in deciding how best to proceed clinically in each case.

Full Text Available Objectives. To investigate the add-on effect of solifenacin for Japanese men with remaining overactive bladder (OAB symptoms after tamsulosin monotherapy for lower urinary tract symptoms (LUTS suggestive of benign prostatic obstruction (BPO in real-life clinical practice. Methods. Patients aged ≥ 50 having remaining OAB symptoms (≥ 3 of OAB symptom score (OABSS with ≥2 of urgency score after at least 4 weeks treatment by 0.2 mg of tamsulosin for BPO/LUTS received 2.5 or 5.0 mg of solifenacin for 12 weeks. The International Prostate Symptom Score (IPSS, QOL index and OABSS, maximum flow rate (Qmax and postvoid residual urine volume (PVR were determined. Results. A total of 48 patients (mean age 72.5 years completed the study. There were significant improvement in IPSS (15.1 to 11.2 and QOL index (4.2 to 3.0 by add-on of solifenacin. Although the IPSS storage symptom score was significantly improved, there were no changes observed in the IPSS voiding symptom score. The OABSS showed significant improvement (8.0 to 4.8. No changes were observed in Qmax and PVR. Conclusions. Under the supervision of an experienced urologist, the additional administration of solifenacin to patients with BPO/LUTS treated with tamsulosin, is effective in controlling remaining OAB symptoms.

To assess the efficacy of tamsulosin, solifenacin, and combination therapy of both agents for the treatment of ureteral stent-related symptoms (SRSs). An open-label, randomized controlled trial was conducted with 112 patients who underwent unilateral ureteral stent insertion following ureteroscopic stone surgery. Patients were randomized with a 2 × 2 factorial design to one of four groups, i.e., A (control), B (tamsulosin 0.2 mg once daily), C (solifenacin 5 mg once daily), and D (both active treatments). Patients were evaluated at week 2 by the ureteral stent symptom questionnaire (USSQ). The primary efficacy outcome was the urinary symptom score of the USSQ, and the secondary efficacy outcomes were the scores in the other five USSQ domains, the Euro-QOL score, and oral analgesic requirements during the 2 weeks. Efficacy outcomes were primarily analyzed for the per-protocol set population. The four groups were generally well balanced in terms of baseline characteristics. Eighty-one patients (72.3 %) completed the study protocol. Comparison of the six USSQ domain scores at week 2 showed no differences between the four groups. Similarly, comparison of the domain scores stratified by tamsulosin or solifenacin medication showed no differences for either medication. The other secondary outcomes were also similar in the group comparisons. Neither tamsulosin nor solifenacin medications provide beneficial effects for relieving various SRSs. In addition, the combination therapy did not have beneficial effects. Further studies are warranted to determine the benefit of medical therapy for the treatment of SRSs and to determine the optimal management strategy for SRSs.

Full Text Available Objectives: To evaluate the impact of the prostatic-urethral angulation (PUA on the treatment efficacy of selective alpha-1A receptor blocker in male patients with lower urinary tract symptoms secondary to benign prostatic hyperplasia (LUTS/BPH. Materials and methods: A total of 80 patients with LUTS/BPH and with mean age 53.3 ± 6.3 (range 47-70 were included in our prospective comparative study. The patients were classified into 2 groups as a consecutive cases 40 in each one depending on the PUA either ≤ 35° (group A or > 35° (group B. PUA and different prostatic parameters were measured using transrectal ultrasound. Prostate-specific antigen (PSA, the International Prostate Symptom Score and quality of life score (IPSS/QoL score, maximum flow rate (Qmax, and postvoid residual (PVR volume were compared between the groups. The clinical significance of PUA was evaluated after 8 weeks of medical treatment with tamsulosin hydrochloride 0.4 mg daily. Results: Baseline evaluation (pre-treatment for both groups were comparable to each other with no clinically significant difference regarding age, PSA, IPSS/QoL score, Qmax and PVR volume (P-value > 0.05. Comparison of parameters after 8 weeks showed that tamsulosin hydrochloride improved the total IPSS and all subscores (P < 0.001, QoL (P = 0.001, Qmax (P = 0.002, and PVR (P = 0.04 in group A (Table 1. Conclusion: Tamsulosin hydrochloride appears to be less effective in improving IPSS/Qol score, Qmax and PVR in patients with lager PUA. The PUA might be a predictor for the treatment efficacy of α-blockers and more studies are warranted in the future before the final conclusion.

To assess treatment satisfaction with tadalafil or tamsulosin vs placebo in a 12-week, randomised, double-blind study of men with lower urinary tract symptoms suggestive of benign prostatic hyperplasia (LUTS/BPH). After a 4-week placebo lead-in period, men aged ≥45 years with an International Prostate Symptom Score (IPSS) of ≥13 and a maximum urinary flow rate of ≥4 to ≤15 mL/s received placebo (172 men), tadalafil 5 mg (171), or tamsulosin 0.4 mg (168) once daily for 12 weeks. Treatment Satisfaction Scale-BPH (TSS-BPH) responses were assessed based on median treatment differences using the van Elteren test. Overall treatment satisfaction was greater for tadalafil vs placebo (P = 0.005), based on greater satisfaction with efficacy (P = 0.003); neither overall treatment satisfaction nor satisfaction with efficacy was greater for tamsulosin vs placebo (P ≥ 0.409). For individual questions, 66.5% of men rated tadalafil treatment as 'effective/very effective' (Question 1, Q1) vs placebo (P = 0.011), 72.6% would 'definitely/probably recommend their treatment' (Q3; P = 0.043), 71.8% were generally 'very satisfied/satisfied with their medication' (Q8; P BPH by baseline age (≤65/>65 years), history of erectile dysfunction (yes/no), LUTS/BPH severity (IPSStamsulosin and placebo. © 2014 The Authors.

Treatment of male lower urinary tract symptoms (LUTS) has traditionally focused on the management of benign prostatic obstruction, but the contribution of bladder dysfunction has been recently recognized. Therefore, it is well understood that LUTS have multifactorial etiology and often occur in clusters and not in isolation. Voiding LUTS are highly prevalent in men, but storage LUTS have been proved to be more bothersome. α1-Blockers are the most widely used pharmacologic agents for the treatment of symptoms relating to benign prostatic enlargement due to benign prostatic hyperplasia (BPH), while antimuscarinics are the drug class of choice for overactive bladder symptoms. A combination of the two drug classes would be a reasonable approach to treat men with both storage and voiding symptoms, and several short-term studies have proved the efficacy and safety of different combinations with an α1-blocker and an antimuscarinic. Following previous studies on the separate administration of solifenacin and tamsulosin, a fixed-dose combination tablet of tamsulosin oral controlled absorption system (OCAS) 0.4 mg and solifenacin succinate 6 mg has been recently introduced, and the current review evaluates the available data on the use of this fixed-dose combination in the treatment of LUTS in men with BPH.

The effects of tamsulosin treatment on changes in frequency-volume chart (FVC) data, especially nighttime urine production, over time were assessed, and the mechanisms underlying the improvement of nocturia in benign prostatic hyperplasia (BPH) patients with nocturnal polyuria (NP) are discussed. A total of 104 patients with lower urinary tract symptoms secondary to BPH were enrolled. After enrollment in the study, the patients were treated with tamsulosin (0.2 mg) once daily. Visits were scheduled every 4 weeks until week 12 (month 3) after study entry, and then every 12 weeks subsequently. All patients completed the International Prostate Symptom Score (IPSS), quality of life (QOL) index, and 3-day FVC, and underwent uroflowmetry at enrollment and on each visit. Eighty-two patients (mean age: 70.9 ± 7.1 years) were analyzed for 24 months after treatment. Patients were divided into two groups, NP and nonNP, based on FVC outcome. The IPSS, QOL index, and maximum flow rate improved during the 24-month period after treatment in both groups. Mean daytime urine volume significantly increased in the NP group, but no changes were detected in the nonNP group. Mean nighttime urine frequency significantly decreased in the NP group over a 24-month period, and was associated with a significant decrease in nighttime urine volume that was not found in the nonNP group. Maximum voided volume increased most months after treatment in both groups. The present long-term prospective study using FVC demonstrated that tamsulosin reduced nighttime urine production in BPH patients with NP. Copyright © 2011 Wiley Periodicals, Inc.

Prophylactic treatment of vestibular migraine

Directory of Open Access Journals (Sweden)

Márcio Cavalcante Salmito

Full Text Available Abstract Introduction: Vestibular migraine (VM is now accepted as a common cause of episodic vertigo. Treatment of VM involves two situations: the vestibular symptom attacks and the period between attacks. For the latter, some prophylaxis methods can be used. The current recommendation is to use the same prophylactic drugs used for migraines, including β-blockers, antidepressants and anticonvulsants. The recent diagnostic definition of vestibular migraine makes the number of studies on its treatment scarce. Objective: To evaluate the efficacy of prophylactic treatment used in patients from a VM outpatient clinic. Methods: Review of medical records from patients with VM according to the criteria of the Bárány Society/International Headache Society of 2012 criteria. The drugs used in the treatment and treatment response obtained through the visual analog scale (VAS for dizziness and headache were assessed. The pre and post-treatment VAS scores were compared (the improvement was evaluated together and individually, per drug used. Associations with clinical subgroups of patients were also assessed. Results: Of the 88 assessed records, 47 were eligible. We included patients that met the diagnostic criteria for VM and excluded those whose medical records were illegible and those of patients with other disorders causing dizziness and/or headache that did not meet the 2012 criteria for VM. 80.9% of the patients showed improvement with prophylaxis (p < 0.001. Amitriptyline, Flunarizine, Propranolol and Topiramate improved vestibular symptoms (p < 0.001 and headache (p < 0.015. The four drugs were effective in a statistically significant manner. There was a positive statistical association between the time of vestibular symptoms and clinical improvement. There was no additional benefit in hypertensive patients who used antihypertensive drugs as prophylaxis or depressed patients who used antidepressants in relation to other prophylactic drugs. Drug

The purpose of this study was to explore the budget impact of dutasteride plus tamsulosin fixed-dose combination (DUT + TAM FDC) versus tamsulosin monotherapy, in the treatment of patients with benign prostatic hyperplasia (BPH) from the perspective of the Greek healthcare insurance system. A Microsoft Excel-based model was developed to estimate the financial consequences of adopting DUT + TAM FDC within the Greek healthcare setting. The model, compared six mutually exclusive health states in two alternative treatment options: current standard of care and the introduction of DUT + TAM FDC in the market. The model used clinical inputs from the CombAT study; data on resource use associated with the management of BPH in Greece were derived from expert panel, and unit cost data were derived from official reimbursement tariffs. A payer perspective was taken into account. As patient distribution data between public and private sectors are not available in Greece two scenarios were investigated, considering the whole eligible population in each scenario. A 4 year time horizon was taken into account and included treatment costs, number of transurethral resections of the prostate (TURPs) and acute urinary retention (AUR) episodes avoided. The clinical benefit from the market adoption of DUT + TAM FDC in Greece was 1,758 TURPs and 972 episodes of AUR avoided cumulatively in a four year period. The increase in total costs from the gradual introduction of DUT + TAM FDC to the Greek healthcare system ranges from €1.3 million in the first year to €5.8 million in the fourth year, for the public sector, and €1.2 million to €4.0 million, for the private sector. This represents an increase of 1.91% to 7.94% for the public sector and 1.10% 3.29% in the private sector, during the 4-year time horizon. Budget impact analysis (BIA) results indicated that the gradual introduction of DUT + TAM FDC, would increase the overall budget of the disease, however providing

Ureteric colic, the term used to describe the pain felt when a stone passes down the ureter from the kidney to the bladder, is a frequent reason for people to seek emergency health care. Treatment with the muscle-relaxant drugs tamsulosin hydrochloride (Petyme, TEVA UK Ltd) and nifedipine (Coracten(®), UCB Pharma Ltd) as medical expulsive therapy (MET) is increasingly being used to improve the likelihood of spontaneous stone passage and lessen the need for interventional procedures. However, there remains considerable uncertainty around the effectiveness of these drugs for routine use. To determine whether or not treatment with either tamsulosin 400 µg or nifedipine 30 mg for up to 4 weeks increases the rate of spontaneous stone passage for people with ureteric colic compared with placebo, and whether or not it is cost-effective for the UK NHS. A pragmatic, randomised controlled trial comparing two active drugs, tamsulosin and nifedipine, against placebo. Participants, clinicians and trial staff were blinded to treatment allocation. A cost-utility analysis was performed using data gathered during trial participation. Urology departments in 24 UK NHS hospitals. Adults aged between 18 and 65 years admitted as an emergency with a single ureteric stone measuring ≤ 10 mm, localised by computerised tomography, who were able to take trial medications and complete trial procedures. Eligible participants were randomised 1 : 1 : 1 to take tamsulosin 400 µg, nifedipine 30 mg or placebo once daily for up to 4 weeks to make the following comparisons: tamsulosin or nifedipine (MET) versus placebo and tamsulosin versus nifedipine. The primary effectiveness outcome was the proportion of participants who spontaneously passed their stone. This was defined as the lack of need for active intervention for ureteric stones at up to 4 weeks after randomisation. This was determined from 4- and 12-week case-report forms completed by research staff, and from the 4

A simple, rapid, sensitive and specific liquid chromatography-tandem mass spectrometry method was developed and validated for quantification of tamsulosin (I), a highly selective alpha1-adrenoceptor antagonist used for the treatment of patients with symptomatic benign prostatic hyperplasia. The analyte and internal standard, mosapride (II) were extracted by liquid-liquid extraction with diethyl ether-dichloromethane (70:30, v/v) using a Glas-Col Multi-Pulse Vortexer. The chromatographic separation was performed on a reverse phase Waters symmetry C18 column with a mobile phase of 0.03% formic acid-acetonitrile (30:70, v/v). The protonated analyte was quantitated in positive ionization by multiple reaction monitoring with a mass spectrometer. The mass transitions m/z 409.1 solidus in circle 228.1 and m/z 422.3 solidus in circle 198.3 were used to measure I and II, respectively. The assay exhibited a linear dynamic range of 0.1-50.0 ng/mL for tamsulosin in human plasma. The lower limit of quantitation was 100 pg/mL with a relative standard deviation of less than 10%. Acceptable precision and accuracy were obtained for concentrations over the standard curve ranges. A run time of 2.0 min for each sample made it possible to analyze a throughput of more than 400 human plasma samples per day. The validated method has been successfully used to analyze human plasma samples for application in pharmacokinetic, bioavailability or bioequivalence studies. (c) 2005 John Wiley & Sons, Ltd.

The Angelina Jolie Effect in Jewish Law: Prophylactic Mastectomy and Oophorectomy in BRCA Carriers

Directory of Open Access Journals (Sweden)

Sharon Galper Grossman

2015-10-01

Full Text Available Background: Following the announcement of actress Angelina Jolie’s prophylactic bilateral mastectomies and subsequent prophylactic oophorectomy, there has been a dramatic increase in interest in BRCA testing and prophylactic surgery. Objective: To review current medical literature on the benefits of prophylactic mastectomy and oophorectomy among BRCA-positive women and its permissibility under Jewish law. Results: Recent literature suggests that in BRCA-positive women who undergo prophylactic oophorectomy the risk of dying of breast cancer is reduced by 90%, the risk of dying of ovarian cancer is reduced by 95%, and the risk of dying of any cause is reduced by 77%. The risk of breast cancer is further reduced by prophylactic mastectomy. Prophylactic oophorectomy and prophylactic mastectomy pose several challenges within Jewish law that call into question the permissibility of surgery, including mutilation of a healthy organ, termination of fertility, self-wounding, and castration. A growing number of Jewish legal scholars have found grounds to permit prophylactic surgery among BRCA carriers, with some even obligating prophylactic mastectomy and oophorectomy. Conclusion: Current data suggest a significant reduction in mortality from prophylactic mastectomy and oophorectomy in BRCA carriers. While mutilation of healthy organs is intrinsically forbidden in Jewish law, the ability to preserve human life may contravene and even mandate prophylactic surgery.

The role of prophylactic cranial irradiation in small cell lung cancer

1996-01-01

To analyse if prophylactic cranial irradiation is small cell lung cancer for improved survival is indicated; if adjuvant irradiation could cure the microscopic disease; if and how late effects could be minimized. Data from randomized trials and retrospective studies are critically analysed related to the incidence of central nervous system (CNS) metastases in limited disease patients in complete remission with or without prophylactic cranial irradiation. The mechanisms of late effects on CNS of prophylactic cranial irradiation and combined treatment are presented. Prophylactic cranial irradiation could decrease the incidence of CNS metastases but could not improve survival. A subgroup of patients (9 to 14%) most likely to benefit from prophylactic cranial irradiation includes patients who are likely to have an isolated CNS failure. The actual used total dose in the range 30 to 40 Gy could only conditionally decrease the CNS failure. Higher total and/or daily doses and combined treatment are related with potentially devastating neurologic and intellectual disabilities. No prospective randomized trial has demonstrated a significant survival advantage for patients treated with prophylactic cranial irradiation. Prophylactic cranial irradiation is capable of reducing the incidence of cerebral metastases and delays CNS failure. A subgroup of patients most likely to benefit from prophylactic cranial irradiation (9 to 14%) includes patients who are likely to have an isolated CNS failure, but this had yet to be demonstrated. The toxicity of treatment is difficult to be influenced. Prophylactic cranial irradiation should not be given concurrently with chemotherapy, a larger interval after chemotherapy is indicated. The total dose should be in the range 30 to 36 Gy and the daily fraction size not larger than 2 Gy. (orig.) [de

Pre-operative prophylactic antibiotics may decrease the frequency of surgical site infection after appendectomy. However, the optimal timing for administration of pre-operative prophylactic antibiotics is unknown. The purpose of this study was to evaluate the effect of timing of prophylactic antibiotics on the frequency of surgical site infection after appendectomy. Medical records were reviewed retrospectively for 577 consecutive patients who had appendectomy for acute appendicitis from 2006 to 2009. Quality assurance guidelines for timing of prophylactic antibiotics before the skin incision were changed from 0 to 30 min before the skin incision (before June 2008) to 30 to 60 min before the skin incision (after June 2008). Surgical site infection occurred in 28 patients (4.9%). There was no difference in frequency of surgical site infection with different timing of pre-operative prophylactic antibiotic (pre-operative time 0 to 30 min: 9 infections [3.6%]; 31 to 60 min: 13 infections [5.4%]; 61 to 120 min: 5 infections [7.0%]; >120 min: 1 infection [6.6%]). Multivariable analysis showed that surgical site infection was associated significantly with medical comorbidity but not perforated appendicitis. The frequency of surgical site infection was independent of timing of preoperative prophylactic antibiotics but was associated with the presence of medical comorbidity.

Full Text Available Postoperative surgical site infections are a major source of illness.  Infection results in longer hospital stay and higher costs.  Uses of preoperative antibiotics have been standardized and are being used routinely in most clinical surgeries and include controversial areas like breast surgery and herniorraphy. Objective of the study is to find out the benefit of prophylactic use of antibiotics in the management of herniorraphy.This project was carried out in a multispeciality tertiary care teaching hospital from 1st-30th April in 2002. Group 1 patients were treated prophylactically half an hour before surgery with single dose of I.V. antibiotics (injection.  Ampicillin 1gm + injection.  Gentamicin 80mg. Group 2 patients were treated post surgery with capsule. Ampicillin 500mg 4 times a day for 7 days and injection. Gentamicin twice a day for first 4 days. In case of group 1 patients only one out of 20 patients (5% was infected.  Whereas in-group 2 patients 5 out of 20 patients (25% were infected. The cost of prophylactic antibiotic treatment was Rs. 25.56 per patient.  The postoperative antibiotic treatment cost was Rs. 220.4 per patient.  That means postoperative treatment is around 8.62 times costlier than prophylactic treatment.             From this study it is evident that prophylactic (preoperative treatment is better than postoperative treatment with antibiotics.

Use of drug therapy in the management of symptomatic ureteric stones in hospitalized adults (SUSPEND), a multicentre, placebo-controlled, randomized trial of a calcium-channel blocker (nifedipine) and an α-blocker (tamsulosin): study protocol for a randomized controlled trial

Science.gov (United States)

2014-01-01

Background Urinary stone disease is common, with an estimated prevalence among the general population of 2% to 3%. Ureteric stones can cause severe pain and have a significant impact on quality of life, accounting for over 15,000 hospital admissions in England annually. Uncomplicated cases of smaller stones in the lower ureter are traditionally treated expectantly. Those who fail standard care or develop complications undergo active treatment, such as extracorporeal shock wave lithotripsy or ureteroscopy with stone retrieval. Such interventions are expensive, require urological expertise and carry a risk of complications. Growing understanding of ureteric function and pathophysiology has led to the hypothesis that drugs causing relaxation of ureteric smooth muscle, such as the selective α-blocker tamsulosin and the calcium-channel blocker nifedipine, can enhance the spontaneous passage of ureteric stones. The use of drugs in augmenting stone passage, reducing the morbidity and costs associated with ureteric stone disease, is promising. However, the majority of clinical trials conducted to date have been small, poor to moderate quality and lacking in comprehensive economic evaluation. This trial aims to determine the clinical and cost-effectiveness of tamsulosin and nifedipine in the management of symptomatic urinary stones. Methods/design The SUSPEND (Spontaneous Urinary Stone Passage ENabled by Drugs) trial is a multicentre, double-blind, randomized controlled trial evaluating two medical expulsive therapy strategies (nifedipine or tamsulosin) versus placebo. Patients aged 18 to 65 with a ureteric stone confirmed by non-contrast computed tomography of the kidney, ureter and bladder will be randomized to receive nifedipine, tamsulosin or placebo (400 participants per arm) for a maximum of 28 days. The primary clinical outcome is spontaneous passage of ureteric stones at 4 weeks (defined as no further intervention required to facilitate stone passage). The

The diastereoselective, trichlorosilane-mediate reduction of imines, bearing different and removable chiral auxiliaries, in combination either with achiral bases or catalytic amounts of chiral Lewis bases, was investigated to afford immediate precursors of chiral APIs (Active Pharmaceutical Ingredients). The carbon-nitrogen double bond reduction was successfully performed in batch and in flow mode, in high yields and almost complete stereocontrol. By this metal-free approach, the formal synthesis of rasagiline and tamsulosin was successfully accomplished in micro(meso) flow reactors, under continuous flow conditions. The results of these explorative studies represent a new, important step towards the development of automated processes for the preparation of enantiopure biologically active compounds.

Amnioinfusion aims to relieve umbilical cord compression during labour by infusing a liquid into the uterine cavity. The objective of this review was to assess the effects of prophylactic amnioinfusion for women in labour with oligohydramnios, but not fetal heart deceleration, compared with therapeutic amnioinfusion only if fetal heart rate decelerations or thick meconium-staining of the liquor occur. We searched the Cochrane Pregnancy and Childbirth Group's Trials Register (28 February 2012). Randomised trials comparing prophylactic amnioinfusion in women in labour with oligohydramnios but not fetal heart rate deceleration in labour with therapeutic amnioinfusion. The authors assessed trial quality and extracted data. One randomized trial of 116 women was included. No differences were found in the rate of caesarean section (risk ratio 1.29, 95% confidence interval 0.60 to 2.74). There were no differences in cord arterial pH, oxytocin augmentation, neonatal pneumonia or postpartum endometritis. Prophylactic amnioinfusion was associated with increased intrapartum fever (risk ratio 3.48, 95% confidence interval 1.21 to 10.05). There appears to be no advantage of prophylactic amnioinfusion over therapeutic amnioinfusion carried out only when fetal heart rate decelerations or thick meconium-staining of the liquor occur.

Prophylactic and thermovision measurements of electric machines and equipment

High-voltage measurements of generators, unit and service transformers and some significant motor drives used at a nuclear power plant are described in this paper. Thermovision measurements of electric machines and distribution systems are dealt with in the second part of the paper. Power electric equipment represent one of the most significant components of a nuclear power plant. Turbine mechanical energy is converted into the electrical energy within these equipment. Power generated by generators is transformed by transformers so that it can achieve appropriate parameters for both the transmission over the distribution system and the power plant service power supply. The service power supply switchboards and cables provide supply to motors and other consumers necessary for the nuclear power plant technological process. The whole complex of equipment has to be maintained in good technical conditions. It is necessary to make thermovision and prophylactic measurements to identify and verify the electric equipment technical condition. The mentioned measurements warn the operation staff in advance against both gradual deterioration of power connection contact resistances, i.e. power connections overheating, and the machine insulation systems condition deterioration. The operation staff try to prevent the electric equipment operation accidents by early removing the detected failures, thus, improving the nuclear safety. In order to provide the above-mentioned activities a special prophylactic measurement group was established at the NPP Bohunice in 1983. The group specialists make following types of measurements. 1. Prophylactic measurements of electric machines. Prophylactics of 220 MW generators and 6 MW service power generators; Prophylactics of both unit and service transformers and VHV bushings; Prophylactics of major 6 kV motor drives. 2. Thermovision measurements of current connections. (Abstract Truncated)

Prophylactic use of octreotide for asparaginase-induced acute pancreatitis.

In the present study, we sought to evaluate the prophylactic use of octreotide for asparaginase-induced acute pancreatitis. We reviewed the medical records of seven patients in two institutions who received prophylactic octreotide for re-administration of asparaginase after asparaginase-induced acute pancreatitis. Three patients completed asparaginase treatment without developing pancreatitis, and four experienced recurrence of pancreatitis. A literature search using PubMed identified four additional patients in whom asparaginase was successfully re-administered with octreotide. Prophylactic use of octreotide may, thus, be warranted for patients who would benefit from re-administration of asparaginase for cancer treatment; however, careful observation is needed to monitor for breakthrough recurrence of pancreatitis.

This study aims to evaluate the association of prophylactic antenatal steroids, indomethacin, and phototherapy with extremely preterm infant outcomes in a pragmatic setting. Retrospective study of infants born at <28 weeks gestation and admitted to 26 Canadian Neonatal Network neonatal intensive care units between 2010 and 2012. Mortality, severe neurological injury, retinopathy, necrotizing enterocolitis, bronchopulmonary dysplasia, nosocomial infection, and patent ductus arteriosus ligation rates were compared between infants who received antenatal steroids, prophylactic indomethacin, and/or prophylactic phototherapy and those who did not. Of 3,465 eligible infants, 2,900 (84%) received antenatal steroids, 269 (8%) prophylactic indomethacin, and 403 (12%) prophylactic phototherapy. Associations were observed between antenatal steroids and mortality (adjusted odds ration [aOR] 0.47 [0.33-0.66]) and severe neurological injury (aOR 0.60 [0.46-0.77]), indomethacin and ductus arteriosus ligations (aOR 0.52 [0.31-0.87]), but not severe neurological injury (aOR 1.12 [0.81-1.54]), but phototherapy was not associated with any of the neonatal outcomes despite reductions in bilirubin. Antenatal steroids were associated with reduced mortality and neurological injury, prophylactic indomethacin was not associated with reduction in neurological injury and phototherapy was not associated with any improvement in neonatal outcomes. In a pragmatic setting, outside randomized controlled trials, the effectiveness and safety of prophylactic interventions in extremely preterm neonates vary; ongoing monitoring is warranted.

Prophylactic intraoperative ureteral stent placement is performed to decrease operative ureteric injury, though few data are available on the effectiveness of this procedure, and no data are available on its cost. To analyze the cost of prophylactic intraoperative cystoscopic ureteral stents in gynecologic surgery. All cases of prophylactic ureteral stent placement performed in gynecologic surgery during a 1-year period were identified and retrospectively reviewed through the electronic medical records database of Summa Health System. Costs were obtained through the Healthcare Cost Accounting System. The principles of cost-effective analysis were used (ie, explicit and detailed descriptions of costs and cost-effectiveness statistics). Importantly, we evaluated cost and not charges or financial model estimates. In addition, we obtained the contribution margins (ie, the hospital's net profit or loss) for prophylactic ureteral stent placement. Other gynecologic procedures were also analyzed. Among 792 major inpatient gynecologic procedures, 18 cases of prophylactic intraoperative ureteral stents were identified. Median costs were as follows: additional cost of prophylactic intraoperative ureteral stenting, $1580; additional cost of surgical resources, $770; cost of ureteral catheters, $427; cost of surgeons, $383. The contribution margins per case for various gynecologic surgical procedures were as follows: oophorectomy, $2804 profit; abdominal hysterectomy, $2649 profit; laparoscopically assisted vaginal hysterectomy (LAVH), $1760 profit. When intraoperative ureteral stenting was added, the contribution margins changed to the following: oophorectomy, $782 profit; abdominal hysterectomy, $627 profit; LAVH, $262 loss. Overall, the contribution margin profit was decreased by about 85%, from $2400 to $380. Prophylactic intraoperative ureteral stenting in gynecologic surgery decreases a hospital's contribution margin. Because of the expense of this procedure, as well as

A two point Nsbnd H⋯O dimer or an infinite catemer are the most preferred motifs/synthons for sulfonamide structures. Such synthons are known to be so robust that they are only disrupted in the presence of highly activated O acceptors such as pyridine-N-oxide and sulfoxide. We demonstrate in this article that a multi-point synthon offered by much weaker ethoxy O and amine N acceptors can however strongly compete and disrupt the robust sulfonamide homosynthons. This has been illustrated with the synthon analysis in three polymorphic crystal structures of R-tamsulosin, an active drug used in the treatment of Benign Prostatic Hyperplasia (BPH) and its hydrochloride salt. These crystalline solids are characterized by Single crystal X-ray diffraction (SC-XRD), powder X-ray diffraction (PXRD), Fourier Transform Infrared (FT-IR) and Raman spectroscopy. Forms I, II of the free base and hydrochloride salt crystallize in the monoclinic P21, C2, and P21 space groups respectively with two molecules in the asymmetric unit (Z‧ = 2), whereas, form III of freebase crystallize in the orthorhombic P212121 space group with Z‧ = 1. Remarkably, all four crystal structures contain a totally unexpected sulfonamide⋯o-diethoxybenzene heterosynthon. The multi-point motifs observed in polymorphs are relatively stronger than those in the hydrochloride salt because of the gauche conformation of the tamsulosin linker chain which renders an additional hydrogen bond interaction with amine N acceptor, and resemble the crown ether sulfonamide recognition pattern. Observation of this new heterosynthon offers potential scope in the design of pharmaceutical cocrystals for sulfonamide bearing drug molecules. The present study also presents a detailed hydrogen bond motif analysis in 310 primary sulfonamide structures culled from the latest version of Cambridge Structural Database (CSD). The role of various competing groups is discussed in the context of understanding the most recurring

Prophylactic and thermovision measurements of electric machines and equipment

High-voltage measurements of generators, unit and service transformers and some significant motor drives used at a nuclear power plant are described in this paper. Thermovision measurements of electric machines and distribution systems are dealt with in the second part of the paper. Power electric equipment represent one of the most significant components of a nuclear power plant. Turbine mechanical energy is converted into the electrical energy within these equipment. Power generated by generators is transformed by transformers so that it can achieve appropriate parameters for both the transmission over the distribution system and the power plant service power supply. The service power supply switchboards and cables provide supply to motors and other consumers necessary for the nuclear power plant technological process. The whole complex of equipment has to be maintained in good technical conditions. It is necessary to make thermovision and prophylactic measurements to identify and verify the electric equipment technical condition. The mentioned measurements warn the operation staff in advance against both gradual deterioration of power connection contact resistances, i.e. power connections overheating, and the machine insulation systems condition deterioration. The operation staff try to prevent the electric equipment operation accidents by early removing the detected failures, thus, improving the nuclear safety. In order to provide the above-mentioned activities a special prophylactic measurement group was established at the NPP Bohunice in 1983. The group specialists make following types of measurements. 1. Prophylactic measurements of electric machines. Prophylactics of 220 MW generators and 6 MW service power generators; Prophylactics of both unit and service transformers and VHV bushings; Prophylactics of major 6 kV motor drives. 2. Thermovision measurements of current connections. Measurements enumarated in paragraph 1 are made on disconnected electric

The spread of infectious diseases can be impacted by human behavior, and behavioral decisions often depend implicitly on a planning horizon-the time in the future over which options are weighed. We investigate the effects of planning horizons on epidemic dynamics. We developed an epidemiological agent-based model (along with an ODE analog) to explore the decision-making of self-interested individuals on adopting prophylactic behavior. The decision-making process incorporates prophylaxis efficacy and disease prevalence with the individuals' payoffs and planning horizon. Our results show that for short and long planning horizons individuals do not consider engaging in prophylactic behavior. In contrast, individuals adopt prophylactic behavior when considering intermediate planning horizons. Such adoption, however, is not always monotonically associated with the prevalence of the disease, depending on the perceived protection efficacy and the disease parameters. Adoption of prophylactic behavior reduces the epidemic peak size while prolonging the epidemic and potentially generates secondary waves of infection. These effects can be made stronger by increasing the behavioral decision frequency or distorting an individual's perceived risk of infection.

Background Artificial cornea transplantation, keratoprosthesis, improves vision for patients at high risk of failure with human cadaveric cornea. However, post-operative infection can cause visual loss and implant extrusion in 3.2–17% of eyes. Long-term vancomycin drops are recommended following keratoprosthesis to prevent bacterial keratitis. Evidence, though, in support of this practice is poor. We investigated whether prophylactic vancomycin drops prevented bacterial keratitis in an animal keratoprosthesis model. Methodology Twenty-three rabbits were assigned either to a prophylactic group (n = 13) that received vancomycin 1.4% drops 5 times/day from keratoprosthesis implantation to sacrifice, or a non-prophylactic group (n = 10) that received no drops. All rabbits had Staphylococcus aureus inoculation into the cornea at 7–12 days post-implantation and were sacrificed at predetermined time-points. Prophylactic and non-prophylactic groups were compared with slit-lamp photography (SLP), anterior segment optical coherence tomography (AS-OCT), and histology, immunohistochemistry and bacterial quantification of excised corneas. Corneal vancomycin pharmacokinetics were studied in 8 additional rabbits. Results On day 1 post-inoculation, the median SLP score and mean±SEM AS-OCT corneal thickness (CT) were greater in the non-prophylactic than the prophylactic group (11 vs. 1, p = 0.049 and 486.9±61.2 vs. 327.4±37.1 μm, p = 0.029 respectively). On days 2 and 4, SLP scores and CT were not significantly different. Immunohistochemistry showed a greater CD11b+ve/non-CD11b+ve cell ratio in the non-prophylactic group (1.45 vs. 0.71) on day 2. Bacterial counts were not significantly different between the two groups. Corneal vancomycin concentration (2.835±0.383 μg/ml) exceeded minimum inhibitory concentration (MIC) for Staphylococcus aureus only after 16 days of vancomycin drops. Two of 3 rabbits still developed infection despite bacterial inoculation after 16 days of

The incidence of postoperative cardiac disturbances and the value of prophylactic digitalization were studied retrospectively in 143 patients undergoing pneumonectomy for carcinoma of the lung. Cardiac arrhythmias occurred in 29% and tachycardia episodes in 30% of the patients. The incidence of myocardial infarction was 2%. Operative mortality was 4%. The cardiac disturbances developed more often after left than after right pneumonectomy. The age of the patients, a history of angina pectoris or hypertension did not markedly increase the incidence of cardiac disturbances, neither did operative factors, such as pericardiotomy, left atrial resection, major bleeding nor postoperative empyema. Prophylactic digitalization significantly reduced postoperative cardiac disorders, their frequency being 33% in the group of patients who received prophylactic digitalis compared with 65% in the group that did not.

We evaluated the therapeutic effects of tamsulosin for women with non-neurogenic voiding dysfunction. Women who had voiding dysfunctions for at least 3 months were included. Inclusion criteria were age ≥18 yr, International Prostate Symptom Score (IPSS) of ≥15, and maximum flow rate (Qmax) of ≥12 mL/sec and/or postvoid residuals (PVR) of ≥150 mL. Patients with neurogenic voiding dysfunction or anatomical bladder outlet obstruction were excluded. All patients were classified according to the Blaivas-Groutz nomogram as having no or mild obstruction (group A) or moderate or severe obstruction (group B). After 8 weeks of treatment, treatment outcomes and adverse effects were evaluated. One hundred and six patients were evaluable (70 in group A, 36 in group B). After treatments, mean IPSS, bother scores, Qmax, PVR, diurnal and nocturnal micturition frequencies and scored form of the Bristol Female Lower Urinary Tract Symptoms questionnaire (BFLUTS-SF) were changed significantly. Eighty-nine patients (84%) reported that the treatment was beneficial. The proportion of patients reported that their bladder symptoms caused "moderate to many severe problems" were significantly decreased. No significant difference were observed between the groups in terms of IPSS, bother score, Qmax, PVR, micturition frequency, and BFLUTS-SF changes. Adverse effects related to medication were dizziness (n=3), de novo stress urinary incontinence (SUI) (n=3), aggravation of underlying SUI (n=1), fatigue (n=1). Tamsulosin was found to be effective in female patients with voiding dysfunction regardless of obstruction grade. PMID:20052356

[Prophylactic treatments of migraine].

Prophylactic treatment is mainly intended to reduce the frequency of migraine attacks. It is usually proposed to patients who suffer from two or more attacks per month. It should also be considered in patients who suffer from less frequent, but prolonged, disabling attacks with a poor response to abortive treatment, and who consider that their quality of life is reduced between attacks. Excessive intake of acute medication, more than twice a week, is a strong indication for prophylactic treatment. In order to obtain a good compliance to treatment, the patient must be informed of the expected efficacy of the drugs, and of their most frequent side effects. Thus, the choice of a prophylactic drug is made together with the patient. Based on the results of published controlled trials, the main prophylactic drugs are some betablockers, methysergide, pizotifene, oxetorone, flunarizine, amitriptyline, NSAIDs, and sodium valproate. Some less evaluated drugs such as aspirin, DHE, indoramine, verapamil, may be useful. Other substances such as riboflavin and new antiepileptic dugs are being evaluated. The choice of the drug to start with depends on several considerations. The first step is to make sure that there are no contra indications, and no possible interaction with the abortive medications. Then, possible side effects will be taken into account, for example, weight gain is a problem for most young women and patients who practice sports may not tolerate betablockers. Associated pathologies have to be checked. For example, a hypertensive migraine sufferers may benefit from betablockers; in a patient who suffers both from migraine and tension type headaches or from depression, amitriptyline is the first choice drug. The type of migraine should also be considered; for instance, in frequent attacks with aura, aspirin is recommended and betablockers avoided. In most cases, prophylaxis should be given as monotherapy, and it is often necessary to try successively several drugs

Phosphodiesterase type 5 inhibitors and α-adrenergic blocking agents (α-blockers) are widely used for the treatment of erectile dysfunction (ED) and lower urinary tract symptoms (LUTS) associated with benign prostatic hyperplasia (BPH). To assess the efficacy and safety of fixed-dose combinations (FDCs) of tamsulosin and tadalafil compared with tadalafil monotherapy in patients with comorbid BPH-associated LUTS and ED. A randomized, double-blinded, active-controlled trial was conducted of 510 men with BPH-associated LUTS and ED. Patients were treated with FDCs of tamsulosin 0.4 mg plus tadalafil 5 mg (FDC 0.4/5 mg), tamsulosin 0.2 mg plus tadalafil 5 mg (FDC 0.2/5 mg), or tadalafil 5 mg for a 12-week treatment period. For a subsequent 12-week extension period, the patients were administered FDC 0.4/5 mg. The primary outcomes were changes from baseline in total International Prostate Symptom Score (IPSS) and International Index of Erectile Function erectile function domain (IIEF-EF) score at week 12 to prove superiority and non-inferiority of FDCs compared with tadalafil 5 mg. The safety assessments were adverse reactions, laboratory test results, and vital signs at week 24. The mean changes in total IPSS and IIEF-EF scores were -9.46 and 9.17 for FDC 0.4/5 mg and -8.14 and 9.49 for tadalafil 5 mg, respectively, which indicated superiority in LUTS improvement (P = .0320) and non-inferiority in ED treatment with FDC 0.4/5 mg compared with tadalafil 5 mg. However, the results from FDC 0.2/5 mg failed to demonstrate superiority in LUTS improvement. No clinically significant adverse events regarding the investigational products were observed during the 24-week period. The FDC 0.4/5 mg is the first combined formulation of an α-blocker and a phosphodiesterase type 5 inhibitor that offers benefits in patient compliance and as add-on therapy in patients with comorbid BPH-associated LUTS and ED. The study clearly demonstrated the advantage of FDC 0.4/5 mg. The main

Wallner, Kent; Roy, Jitendra; Harrison, Louis

1996-01-01

Purpose: To determine the incidence of postimplant infection in patients who are not given prophylactic antibiotics (ATBs). Methods and Materials: One hundred thirty-one patients had computerized tomography (CT)-planned transperineal 125 I implantation of the prostate from 1988 through 1995. One hundred fourteen of the patients did not receive prophylactic ATBs, 19 of whom required postimplant Foley catheter drainage for 1 day or more for acute urinary retention. Results: The incidence of postimplant febrile episodes within 2 weeks of surgery among the patients who had not received prophylactic ATBs was 2 of 114 (2%). One of the two patients who developed postimplantation febrile episodes was treated successfully with ATBs as an outpatient. The second patient, who had a history of chronic lymphocytic leukemia (CLL) and immune suppression, developed E. coli sepsis and required intravenous antibiotics. Of 17 patients who received prophylactic ATBs, none had a postoperative febrile episode. Conclusion: We continue to refrain from routinely prescribing prophylactic ATBs unless there is some compelling circumstance including rheumatic heart disease, prosthetic devices, immune compromise, or a previous history of prostatitis

Kapoor, Anil

2012-10-01

Benign prostate hyperplasia (BPH) occurs in up to 50% of men by age 50, and the incidence increases with age. This common clinical problem is diagnosed by history, including the International Prostate Symptom Score (IPSS) questionnaire, and physical examination by digital rectal examination (DRE). Initial management for BPH includes lifestyle modification, and smooth muscle relaxant alpha blocker therapy. Alpha blockers usually take effect quickly within 3-5 days, and have minimal side effects. Current commonly used alpha blockers include the selective alpha blockers tamsulosin (Flomax), alfusosin (Xatral), and silodosin (Rapaflo). For patients with larger prostates, the 5-alpha reductase inhibitor class (finasteride (Proscar) and dutasteride (Avodart)) work effectively to shrink prostate stroma resulting in improved voiding. The 5-ARI class of drugs, in addition to reducing prostate size, also reduce the need for future BPH-related surgery, and reduce the risk of future urinary retention. Drugs from the phosphodiesterase-5 (PDE-5) inhibitor class may now be considered for treating BPH. Once daily 5 mg tadalafil has been shown to improve BPH-related symptoms and is currently approved to treat patients with BPH. Referral to a urologist can be considered for patients with a rising prostate-specific antigen (PSA), especially while on 5-ARI, failure of urinary symptom control despite maximal medical therapy, suspicion of prostate cancer, hematuria, recurrent urinary infections, urinary retention, or renal failure. Currently the primary care physician is armed with multiple treatment options to effectively treat men with symptomatic BPH.

Full Text Available Expediency of the development of formulae and innovative technologies for production of prophylactic application drinks possessing antioxidant, probiotic and hepatoprotective properties with the use of the secondary dairy product – whey, as well as the domestic vegetable raw materials having a high content of bioactive substances has been substantiated.Formulation composition of the prophylactic drinks based on cheese whey, extract of Tagetes patula flowers and the berry filler “Strawberry” with the use of the response surface method has been developed. Bioactivity of the drinks and the complex quality indicator which accounts for the total influence of the bioactivity, organoleptic assessment and weight coefficients of the specified unit indicators were taken as the optimization criteria; as the independent factors that were varied in the course of the experiment, the mass fractions of the marigold flowers extract and the strawberries filler were selected. It is recommended that the mass fractions of the berry filler “Strawberry” and the extract of Tagetes patula flowers in the prophylactic drinks are set as 7 and 20 % of the finished product, accordingly. The practical mass fraction of the citric acid of 0.2 % was determined as it ensures high organoleptic characteristics of the finished drinks. Recommendations are given concerning development of innovative technologies of unfermented and fermented strawberry whey drinks of prophylactic application enriched with the extract of Tagetes patula flowers.

The objective of this study was to examine the effect of prophylactic continuous positive airway pressure (CPAP) on infants born in 25 South American neonatal intensive care units affiliated with the Neocosur Neonatal Network using novel multivariate matching methods. A prospective cohort was constructed of infants with a birth weight 500 to 1500 g born between 2005 and 2011 who clinically were eligible for prophylactic CPAP. Patients who received prophylactic CPAP were matched to those who did not on 23 clinical and sociodemographic variables (N=1268). Outcomes were analyzed using the McNemar's test. Infants not receiving prophylactic CPAP had higher mortality rates (odds ratio (OR)=1.69, 95% confidence interval (CI) 1.17, 2.46), need for any mechanical ventilation (OR=1.68, 95% CI 1.33, 2.14) and death or bronchopulmonary dysplasia (BPD) (OR=1.47, 95% CI 1.09, 1.98). The benefit of prophylactic CPAP varied by birth weight and gender. The implementation of this process was associated with a significant improvement in survival and survival free of BPD.

Identify factors associated with the prophylactic prescription of a bowel regimen with an inpatient opioid prescription. This was a retrospective cohort study from June 1, 2013, to October 31, 2014 of pediatric inpatients prescribed an oral or intravenous opioid on the general medical/surgical floors. We identified patients with or without a prophylactic prescription of a bowel regimen. We obtained patient demographics, prescriber training level and service and used multivariate logistic regression to analyze the factors associated with prophylactic bowel regimen and opioid prescription. Of the 6682 encounters that met study criteria, only 966 (14.5%) encounters had prophylactic prescriptions. Patient factors associated with prophylactic prescription include increasing age (per year; odds ratio [OR] = 1.06, 95% confidence interval [CI] 1.05-1.07) and sickle cell diagnosis (OR = 3.19, 95% CI 2.08-4.91). Medication factors associated with prophylactic prescription include a scheduled opioid prescription (OR = 1.75, 95% CI 1.46-2.1) and a prescription for oxycodone (OR = 3.59, 95% CI 2.57-5.00) or morphine (OR = 1.84, 95% CI 1.39-2.44), compared with acetaminophen-hydrocodone. Compared with medical providers, surgeons were less likely (OR = 0.43, 95% CI 0.35-0.53) and pain service providers were more likely to prescribe a prophylactic bowel regimen (OR = 4.12, 95% CI 3.13-5.43). More than 85% of inpatient opioid prescriptions did not receive a prophylactic bowel regimen. Future research should examine factors (eg, clinical decision support tools) to increase prophylactic prescription of bowel regimens with opioids for populations found to have lower rates.

This paper explores the opinions, motives and expectations of patients regarding prophylactic migraine therapy. Methods A qualitative focus group study in general practice in the Netherlands with twenty patients recruited from urban and rural general practices. Three focus group meetings were held with 6-7 migraine patients per group (2 female and 1 male group. All participants were migraine patients according to the IHS (International Headache Society; 9 had experience with prophylactic medication. The focus group meetings were analysed using a general thematic analysis. Results For patients several distinguished factors count when making a decision on prophylactic treatment. The decision of a patient on prophylactic medication is depending on experience and perspectives, grouped into five categories, namely the context of being active or passive in taking the initiative to start prophylaxis; assessing the advantages and disadvantages of prophylaxis; satisfaction with current migraine treatment; the relationship with the physician and the feeling to be heard; and previous steps taken to prevent migraine. Conclusion In addition to the functional impact of migraine, the decision to start prophylaxis is based on a complex of considerations from the patient's perspective (e.g. perceived burden of migraine, expected benefits or disadvantages, interaction with relatives, colleagues and physician. Therefore, when advising migraine patients about prophylaxis, their opinions should be taken into account. Patients need to be open to advice and information and intervention have to be offered at an appropriate moment in the course of migraine.

The lifetime probability of death from gastric dilation-volvulus (GDV) for five dog breeds was estimated based on published breed-specific longevity and GDV incidence. These breeds were Great Dane, Irish Setter, Rottweiler, Standard Poodle and Weimaraner. Lifetime risk (95% CI) of GDV in these breeds ranged from 3.9% (0-11.2%) for Rottweiler to 36.7% (25.2-44.6%) for Great Dane. A decision-tree analysis for prophylactic gastropexy--using lifetime probability of death from GDV and expected cost savings for veterinary services as outcome measures--was undertaken to determine the preferred course of action in several dog breeds. Prophylactic gastropexy was the preferred choice of action for all breeds examined, with the reduction in mortality (versus no gastropexy) ranging from 2.2-fold (Rottweiler) to 29.6-fold (Great Dane). Assuming a prophylactic gastropexy costs US$ 400, the procedure was cost-effective when the lifetime risk of GDV was > or = 34%. The maximum and minimum estimated breakeven costs for the gastopexy procedure ranged from US$ 20 (Rottweiler) to US$ 435 (Great Dane). The cost-effectiveness of prophylactic gastropexy was most sensitive to the cost of treating GDV (US$ 1500). Prophylactic gastropexy raises ethical issues that need to be considered by veterinarians and dog breeders.

Aim: To assess outcomes and usage rate of prophylactic radiologically inserted gastrostomy (RIG) in head and neck cancer (HNC) patients. Materials and methods: Outcome data of all HNC patients who underwent prophylactic RIG over a 22-month period (November 2007 to September 2009) in a tertiary referral centre were collected retrospectively. Thirty-day mortality, major and minor complication rates, and subsequent usage of the RIG were analysed. Results: Fifty-one HNC patients underwent prophylactic RIG. Three minor and no major immediate complications were identified. Sixteen minor and three major complications at 30-days were identified. Three (5.9%) major complications were identified. There was one death due to disease progression and not RIG insertion. The RIG was not used in 17.7% of patients post-procedure. Conclusion: Prophylactic RIG in HNC patients has a comparable mortality rate to RIG insertion in HNC patients with mixed indications. However, the number of cases where the gastrostomy is not used raises important concerns and warrants further investigation.

Full Text Available The duration of ejaculatory suppression of alpha adrenoceptor antagonist (tamsulosin, TAM was investigated in goats. Five males were injected intramuscularly with TAM 80 μg/kg (179.8 nmol/kg. Semen was collected using an artificial vagina with estrous female goats and the semen quality and libido score were evaluated at 1, 3, 6 and 9 h post TAM injection. Two replicates were carried out in the study. Heart rates were also measured before the injection and at 30 min before semen collection. The results showed that the libido score was not affected by TAM. At 1 h post injection, the highest percentage of suppressed ejaculation (80% was recorded and this effect was maintained for up to 3 h post injection (60%. Thereafter the percentage of suppressed ejaculation was significantly decreased (p < 0.05 at 6 h (20% and ejaculation was completely recovered at 9 h post injection. The semen characteristics of the collectable semen, semen volume and number of spermatozoa were lowest at 1 h and 3 h, thereafter they suddenly increased at 6 h and the significantly highest peak was noted at 9 h post injection. TAM injection suppressed goat ejaculation within 1 h and the duration was maintained up to 3 h post injection.

To test the hypothesis that prophylactic dextrose gel administered to newborn infants at risk for hypoglycemia will increase the initial blood glucose concentration after the first feeding and decrease neonatal intensive care unit (NICU) admissions for treatment of asymptomatic neonatal hypoglycemia compared with feedings alone. This quasi-experimental study allocated asymptomatic at-risk newborn infants (late preterm, birth weight 4000 g, and infants of mothers with diabetes) to receive prophylactic dextrose gel (Insta-Glucose; Valeant Pharmaceuticals North America LLC, Bridgewater, New Jersey); other at-risk infants formed the control group. After the initial feeding, the prophylactic group received dextrose gel (0.5 mL/kg) rubbed into the buccal mucosa. The blood glucose concentration was checked 30 minutes later. Initial glucose concentrations and rate of NICU admissions were compared between the prophylactic group and controls using bivariate analyses. A multivariable linear regression compared first glucose concentrations between groups, adjusting for at-risk categories and age at first glucose concentration. There were 236 subjects (72 prophylactic, 164 controls). The first glucose concentration was not different between the prophylactic and control groups in bivariate analysis (52.1 ± 17.1 vs 50.5 ± 15.3 mg/dL, P = .69) and after adjusting for covariates (P  = .18). Rates of NICU admission for treatment of transient neonatal hypoglycemia were 9.7% and 14.6%, respectively (P = .40). Prophylactic dextrose gel did not reduce transient neonatal hypoglycemia or NICU admissions for hypoglycemia. The carbohydrate concentration of Insta-Glucose (77%) may have caused a hyperinsulinemic response, or alternatively, exogenous enteral dextrose influences glucose homeostasis minimally during the first few hours when counter-regulatory mechanisms are especially active.

Infection with human papilloma virus (HPV) has been identified as the cause of recurrent papillomatosis and of a subgroup of squamous cell carcinomas of the head and neck. A change in prevalence of these lesions, especially for oropharyngeal carcinoma, can be expected as a consequence of the introduction of prophylactic HPV vaccines for young women, targeting the most frequent high- and low-risk HPV subtypes. Vaccination for the major low-risk HPV types has proven to be highly effective against genital warts and activity against papillomatosis can be expected. The possibilities of prophylactic HPV vaccination as well as new developments and the rationale for therapeutic vaccines are discussed on the basis of the current literature.

Objective: To discuss the effects of prophylactic chemotherapy on the outcomes and prognosis of invasive mole patients. Methods: One hundred and fifteen invasive mole (IM) patients older than 40 years were registered in Peking Union Medical Collage Hospital.Eleven of them were treated with prophylactic chemotherapy before diagnosed as IM prophylactic chemotherapy group, while the other 104 cases received therapeutic chemotherapy after diagnosed as IM (non-prophylactic chemotherapy group). The general clinical data (including age, clinical stage, risk factor score), treatment, outcomes and relapse of patients were retrospectively compared between two groups. Results: (1) The age of prophylactic chemotherapy group and non-prophylactic chemotherapy group were (47±5) versus (46±4) years old. Ratio of clinical stageⅠ-Ⅱ were 3/11 versus 29.8% (31/104), clinical stage Ⅲ-Ⅳ were 8/11 versus 70.2% (73/104). Ratio of risk factor score 0-6 were 11/11 versus 84.6% (88/104), risk factor score >6 were 0 versus 15.4% (16/104). There were no significant statistical differences between two groups in age, clinical stage or risk factor score (all P> 0.05). (2) Treatment: the total chemotherapy courses between prophylactic chemotherapy group and non-prophylactic chemotherapy group (median 7 versus 5) were significantly different ( Z= 3.071, P= 0.002). There were no significant statistical differences between two groups in the chemotherapy courses until negative conversion of β-hCG, consolidation chemotherapy courses, total therapeutic chemotherapy courses or ratio of hysterectomy (all P> 0.05). (3) Outcomes and relapse: between the prophylactic chemotherapy group and the non-prophylactic chemotherapy group, the complete remission rate were 11/11 versus 98.1%(102/104), the relapse rate were 0 versus 1.0%(1/102). There were no significant difference between the two groups in outcomes or relapse rate ( P> 0.05). Conclusions: Prophylactic chemotherapy does not substantially

Despite limited evidence, postoperative prophylactic antibiotics are often used in the setting of permanent pacemaker implantation or replacement. The aim of this study is to investigate the efficacy of postoperative antibiotics. Postoperative prophylactic antibiotics may be not clinically useful. We recruited 367 consecutive patients undergoing permanent pacemaker implantation or generator replacement at a tertiary referral center. Baseline demographics, clinical characteristics, and procedure information were collected, and all patients received preoperative prophylactic antibiotics. Postoperative prophylactic antibiotics were administered at the discretion of the treating physician, and all patients were seen in follow-up every 3 to 6 months for an average follow-up period of 16 months. The primary endpoint was device-related infection. A total of 110 patients were treated with preoperative antibiotics only (group 1), whereas 257 patients received both preoperative and postoperative antibiotics (group 2). After a mean follow-up period of 16 months, 1 patient in group 1 (0.9%) and 4 patients in group 2 (1.5%) experienced a device-related infection. There was no significant difference in the rate of infection between the 2 groups (P = 0.624). In the univariate analysis, only the age (60 ± 11 vs 75 ± 12 years, P antibiotics had a similar rate of infection as those treated with preoperative antibiotics alone. Further studies are needed to confirm these preliminary findings. © 2017 Wiley Periodicals, Inc.

Should patients with Björk-Shiley valves undergo prophylactic replacement?

1992-08-29

About 85,000 patients have undergone replacement of diseased heart valves with prosthetic Björk-Shiley convexo-concave (CC) valves. These valves are prone to fracture of the outlet strut, which leads to acute valve failure that is usually fatal. Should patients with these valves undergo prophylactic replacement to avoid fracture? The incidence of strut fracture varies between 0% and 1.5% per year, depending on valve opening angle (60 degrees or 70 degrees), diameter (less than 29 mm or greater than or equal to 29 mm), and location (aortic or mitral). Other factors include the patient's life expectancy and the expected morbidity and mortality associated with reoperation. We have used decision analysis to identify the patients most likely to benefit from prophylactic reoperation. The incidence of outlet strut fracture was estimated from the data of three large studies on CC valves, and stratified by opening angle, diameter, and location. A Markov decision analysis model was used to estimate life expectancy for patients undergoing prophylactic valve replacement and for those not undergoing reoperation. Prophylactic valve replacement does not benefit patients with CC valves that have low strut fracture risks (60 degrees aortic valves and less than 29 mm, 60 degrees mitral valves). For most patients with CC valves that have high strut fracture risks (greater than or equal to 29 mm, 70 degrees CC), prophylactic valve replacement increases life expectancy. However, elderly patients with such valves benefit from prophylactic reoperation only if the risk of operative mortality is low. Patient age and operative risk are most important in recommendations for patients with CC valves that have intermediate strut fracture risks (less than 29 mm, 70 degrees valves and greater than or equal to 29 mm, 60 degrees mitral valves). For all patients and their doctors facing the difficult decision on whether to replace CC valves, individual estimates of operative mortality risk that

The indications for prophylactic antibiotics in plastic surgery remain controversial. No recent survey has been reported on the use of prophylactic antibiotics by plastic surgeons in clinical practice. This survey was designed to assess the current use of prophylactic antibiotics by plastic surgeons and to compare trends with previous studies. All members of the American Society of Plastic Surgeons with an e-mail address on the Society's website were contacted via an e-mail and sent a link to a SurveyMonkey questionnaire. To survey only in those subspecialty areas that they practice in, surgeons were queried only on the procedures that they perform. Within each section, a list of common representative procedures was included, with questions about the use of antibiotic prophylaxis. A total of 3824 American Society of Plastic Surgeons members were contacted. Of the 3613, 910 with working e-mail addresses responded to the survey for a response rate of 25%. And 833 or 91.5% completed the survey. Survey data cover the percentage of surgeons reporting their use of antibiotics in procedures that they currently perform. The percentage of plastic surgeons who use prophylactic antibiotics in almost all procedures studied has increased significantly when compared with earlier studies. The use of prophylactic antibiotics by plastic surgeons has increased considerably since the prior studies by Krizek et al (Plast Reconstr Surg. 1975;55:21-32 and 1985;76:953-963). Some of these uses are appropriate because of the use in procedures involving implants and longer operations. The elevated rates for clean procedures are not part of the evidence-based practice.

We conducted a clinical trial to determine if prophylactic anticonvulsants in brain tumour patients (without prior seizures) reduced seizure frequency. We stopped accrual at 100 patients on the basis of the interim analysis. One hundred newly diagnosed brain tumour patients received anticonvulsants (AC Group) or not (No AC Group) in this prospective randomized unblinded study. Sixty patients had metastatic, and 40 had primary brain tumours. Forty-six (46%) patients were randomized to the AC Group and 54 (54%) to the No AC Group. Median follow-up was 5.44 months (range 0.13 -30.1 months). Seizures occurred in 26 (26%) patients, eleven in the AC Group and 15 in the No AC Group. Seizure-free survivals were not different; at three months 87% of the AC Group and 90% of the No AC Group were seizure-free (log rank test, p=0.98). Seventy patients died (unrelated to seizures) and survival rates were equivalent in both groups (median survival = 6.8 months versus 5.6 months, respectively; log rank test, p=0.50). We then terminated accrual at 100 patients because seizure and survival rates were much lower than expected; we would need ≥900 patients to have a suitably powered study. These data should be used by individuals contemplating a clinical trial to determine if prophylactic anticonvulsants are effective in subsets of brain tumour patients (e.g. only anaplastic astrocytomas). When taken together with the results of a similar randomized trial, prophylactic anticonvulsants are unlikely to be effective or useful in brain tumour patients who have not had a seizure. (author)

Maternity care providers administer oxytocin prophylactically to prevent postpartum hemorrhage (PPH). Prophylactic oxytocin is generally considered effective and safe and is promoted by national organizations for standardized use. In this article, the evidence supporting prophylactic oxytocin administration for women undergoing spontaneous labor and birth compared with women whose labors included administration of exogenous oxytocin for induction or augmentation is explored. Using data from randomized controlled trials included in 2 recent Cochrane meta-analyses papers, only studies with women in spontaneous labor were selected for inclusion (N = 4 studies). Outcomes of immediate postpartum bleeding volumes (≥ 500 mL or 1000 mL), risk for blood transfusion, and risk for administration of more uterotonic medication were pooled from these 4 studies. Focused random effects meta-analytics were used. Compared to women without prophylactic oxytocin, women who received prophylactic oxytocin had a lower risk of having a 500 mL or higher blood loss. However, prophylactic oxytocin did not lower risk of PPH (≥ 1000 mL), blood transfusion, or need for additional uterotonic treatment. Prophylactic oxytocin may not confer the same benefits to women undergoing spontaneous labor and birth compared to women laboring with oxytocin infusion. Reasons for this difference are explored from a pharmacologic perspective. In addition, the value of prophylactic oxytocin given recent changes in the definition of PPH from greater than or equal to 500 mL to 1000 mL or more after birth is discussed. Finally, gaps in research on adverse effects of prophylactic oxytocin are presented. More research is needed on reducing risk of PPH for women in spontaneous labor. © 2017 by the American College of Nurse-Midwives.

Active management of the third stage of labour has been shown to reduce the risk of postpartum haemorrhage (PPH) greater than 1000 mL. One aspect of the active management protocol is the administration of prophylactic uterotonics, however, the type of uterotonic, dose, and route of administration vary across the globe and may have an impact on maternal outcomes. To determine the effectiveness of prophylactic oxytocin at any dose to prevent PPH and other adverse maternal outcomes related to the third stage of labour. We searched the Cochrane Pregnancy and Childbirth Group's Trials Register (31 May 2013). Randomised or quasi-randomised controlled trials including pregnant women anticipating a vaginal delivery where prophylactic oxytocin was given during management of the third stage of labour. The primary outcomes were blood loss > 500 mL and the use of therapeutic uterotonics. Two review authors independently assessed trials for inclusion, assessed trial quality and extracted data. Data were checked for accuracy. This updated review included 20 trials (involving 10,806 women). Prophylactic oxytocin versus placebo Prophylactic oxytocin compared with placebo reduced the risk of PPH greater than 500 mL, (risk ratio (RR) 0.53; 95% confidence interval (CI) 0.38 to 0.74; six trials, 4203 women; T² = 0.11, I² = 78%) and the need for therapeutic uterotonics (RR 0.56; 95% CI 0.36 to 0.87, four trials, 3174 women; T² = 0.10, I² = 58%). The benefit of prophylactic oxytocin to prevent PPH greater than 500 mL was seen in all subgroups. Decreased use of therapeutic uterotonics was only seen in the following subgroups: randomised trials with low risk of bias (RR 0.58; 95% CI 0.36 to 0.92; three trials, 3122 women; T² = 0.11, I² = 69%); trials that performed active management of the third stage (RR 0.39; 95% CI 0.26 to 0.58; one trial, 1901 women; heterogeneity not applicable); trials that delivered oxytocin as an IV bolus (RR 0.57; 95% CI 0.39 to 0.82; one trial, 1000 women

The narrow field of non-controversial indications concerning the application of digitalis glycosides is pointed out. Problems of routine digitalization of older patients not suffering from cardiac insuffiency are discussed with special regard to preparing them for operations. Up to now, from the viewpoint of anaesthesiologists no benefits of prophylactic digitalization have been found. In a retrospective computerized study, clinical hemodynamic parameters during introduction of anaesthesia have been investigated by means of anaesthetic data recorded during three years. Nondigitalized patients older than fifty years showed satisfactory cardiac functions, whereas prophylactically digitalized patients--compared with the control group--have been treated with plasma expanders earlier and at a double rate. Furthermore, higher heart frequencies and greater tendency to arrythmias were observed. Consequently, prophylactic digitalization cannot be recommended in general.

Prophylactic knee bracing alters lower-limb muscle forces during a double-leg drop landing.

Anterior cruciate ligament (ACL) injury can be a painful, debilitating and costly consequence of participating in sporting activities. Prophylactic knee bracing aims to reduce the number and severity of ACL injury, which commonly occurs during landing maneuvers and is more prevalent in female athletes, but a consensus on the effectiveness of prophylactic knee braces has not been established. The lower-limb muscles are believed to play an important role in stabilizing the knee joint. The purpose of this study was to investigate the changes in lower-limb muscle function with prophylactic knee bracing in male and female athletes during landing. Fifteen recreational athletes performed double-leg drop landing tasks from 0.30m and 0.60m with and without a prophylactic knee brace. Motion analysis data were used to create subject-specific musculoskeletal models in OpenSim. Static optimization was performed to calculate the lower-limb muscle forces. A linear mixed model determined that the hamstrings and vasti muscles produced significantly greater flexion and extension torques, respectively, and greater peak muscle forces with bracing. No differences in the timings of peak muscle forces were observed. These findings suggest that prophylactic knee bracing may help to provide stability to the knee joint by increasing the active stiffness of the hamstrings and vasti muscles later in the landing phase rather than by altering the timing of muscle forces. Further studies are necessary to quantify whether prophylactic knee bracing can reduce the load placed on the ACL during intense dynamic movements. Copyright © 2016 Elsevier Ltd.

The current status of prophylactic replacement therapy in children and adults with haemophilia.

Ljung, Rolf; Gretenkort Andersson, Nadine

2015-06-01

Initiating prophylactic treatment at an early age is considered to be the optimal form of therapy for a child with haemophilia A or B. The pioneering long term experiences of prophylactic treatment from Sweden and The Netherlands demonstrated the benefit of prophylaxis in retrospective and observational studies. Decades later, these benefits were confirmed in a randomized controlled study in USA. We review the current status of prophylactic replacement therapy of haemophilia in children, adolescents, adults and the elderly. Prophylaxis should begin at an early age and there are arguments for continuing it into adulthood. The dose of prophylaxis is dependent on the goal of treatment, economic resources and venous access and should be tailored individually. Starting the first exposures to clotting factor concentrates as prophylactic treatment, instead of on-demand in response to a bleed, may decrease the frequency of inhibitors in patients with haemophilia A. Novel longer-acting products are being introduced that could be helpful for patients with difficult venous access and enable higher trough levels. © 2015 John Wiley & Sons Ltd.

We conducted this study to clarify the current clinical practice of prophylactic colectomy for patients with familial adenomatous polyposis (FAP) in Japan. This retrospective multi-center cohort study involved 23 specialized institutions for colorectal disease in Japan. We analyzed the records of 147 patients who underwent prophylactic surgical treatment between 2000 and 2012. Patients were divided into Group 1 (2000-2006) and Group 2 (2007-2012) based on their date of surgery. Age at the time of prophylactic surgery was 27 and 31 years in Groups 1 and 2, respectively. The proportion of attenuated FAP was significantly lower in Group 2 than in Group 1 (1.0 vs. 13 %, respectively). Pathological examination revealed an increased incidence of malignant polyps in the resected specimens from Group 2 patients (10 vs. 23 %, respectively; P = 0.034). Laparoscopic surgery was more frequent in Group 2 than in Group 1 (61 vs. 40 %, respectively). There was no surgical mortality in either group. Prophylactic surgery for FAP results in good short-term surgical outcomes in Japan. The current surgical approach is characterized by limited surgical indications for patients with attenuated FAP, delayed timing of colectomy, and the increasing standardization of laparoscopic surgery.

The purpose of this study was to examine the cost-effectiveness of prophylactic fixation of the uninjured hip to prevent contralateral hip fracture. : A Markov state-transition model was used to evaluate the cost and quality-adjusted life-years (QALYs) for unilateral fixation of hip fracture alone (including internal fixation or arthroplasty) compared with unilateral fixation and contralateral prophylactic hip fixation performed at the time of hip fracture or unilateral fixation and bilateral hip pad protection. Prophylactic fixation involved placement of a cephalomedullary nail in the uninjured hip and was initially assumed to have a relative risk of a contralateral fracture of 1%. Health states included good health, surgery-related complications requiring a second operation (infection, osteonecrosis, nonunion, and malunion), fracture of the uninjured hip, and death. The primary outcome measure was the incremental cost-effectiveness ratio estimated as cost per QALY gained in 2006 US dollars with incremental cost-effectiveness ratios below $50,000 per QALY gained considered cost-effective. Sensitivity analyses evaluated the impact of patient age, annual mortality and complication rates, intervention effectiveness, utilities, and costs on the value of prophylactic fixation. : In the baseline analysis, in a 79-year-old woman, prophylactic fixation was not found to be cost-effective (incremental cost-effectiveness ratio = $142,795/QALY). However, prophylactic fixation was found to be a cost-effective method to prevent contralateral hip fracture in: 1) women 71 to 75 years old who had 30% greater relative risk for a contralateral fracture; and 2) women younger than age 70 years. Cost-effectiveness was greater when the additional costs of prophylaxis were less than $6000. However, for

AIM: To investigate the role of prophylactic antibiotics in the reduction of mortality of severe acute pancreatitis (SAP) patients, which is highly questioned by more and more randomized controlled trials (RCTs) and meta-analyses. METHODS: An updated meta-analysis was performed. RCTs comparing prophylactic antibiotics for SAP with control or placebo were included for meta-analysis. The mortality outcomes were pooled for estimation, and re-pooled estimation was performed by the sensitivity analysis of an ideal large-scale RCT. RESULTS: Currently available 11 RCTs were included. Subgroup analysis showed that there was significant reduction of mortality rate in the period before 2000, while no significant reduction in the period from 2000 [Risk Ratio, (RR) = 1.01, P = 0.98]. Funnel plot indicated that there might be apparent publication bias in the period before 2000. Sensitivity analysis showed that the RR of mortality rate ranged from 0.77 to 1.00 with a relatively narrow confidence interval (P antibiotic prophylaxis. CONCLUSION: Current evidences do not support prophylactic antibiotics as a routine treatment for SAP, but the potentially benefited sub-population requires further investigations. PMID:22294832

A RANDOMIZED CONTROLLED STUDY OF RISK FACTORS AND ROLE OF PROPHYLACTIC ANTIBIOTICS IN PREVENTION OF SURGICAL SITE INFECTIONS

2015-01-01

Full Text Available Background and Objectives: Surgical site infection (SSI is the most common nosocomial infection encountered in post operative surgical wards. The use of prophylactic antibiotic in clean elective surgical cases is still a subject of controversy to surgeons. The objective of the study is to identify the need for using prophylactic antibiotics in clean surgeries, prevalence of organisms in patients who are not given prophylactic antibiotics and to study whether the presence of risk factors increase the incidence of surgical site infection. Methodology: The comparative study consists of 100 cases admitted under two groups of 50 each: Group A was given prophylactic antibiotic and Group B didn’t receive any. All surgeries other than clean surgical cases were excluded from the study. Results: Out of 50 patients in group B who were not given prophylactic antibiotic, 2 patients had more than one risk factor for development of SSI and both of them developed SSI. Of the 50 patients who received prophylactic antibiotic, none developed SSI. The rate of infection in group A was nil and in Group B was 4%. Conclusion: Prophylactic antibiotics are not recommended for clean elective surgical cases as there is no statistically significant change in the infection rate seen in patients not receiving prophylactic antibiotic(P=0.4952. Meticulous surgical technique and correcting risk factors prior to surgery is a must for reducing incidence of SSI.

Efficacy of prophylactic phototherapy for prevention of hyperbilirubinemia in very low birth weight newborns

Full Text Available Background: Jaundice is a common clinical condition in newborn occurring in approximately 60% of term and 80% of preterm infants. Unconjugated hyperbilirubinemia is universally common in all preterm infants especially in newborns with very low biLth weight. Low birth weight and premature infants are at major risk for exaggerated hyperbilirubinemia that can lead to bilirubin encephalopathy. Significant heterogeneity in the approach to the treatment of jaundiced neonates exists throughout the world. Phototherapy is the most common treatment for neonatal hyperbilirubinemia and could be most effective in preventing the sequelae of hyperbilirubinemia if initiated prophylactically. This randomized clinical trial has been proposed with the objective of assessing the efficacy of prophylactic photo therapy in preventing significant rise of unconjugated hyperbilirubinemia in premature neonates weighing less than 1500 gram and therefore to decrease the need for exchange transfusion and finally to reduce hospital stay due to hyperbilirubinemia. Methods: This randomized controlled clinical trial enrolled sixty newborns with birth weight less than 1500 gram. They were divided into two groups: 1 Prophylactic group, in whom phototherapy was started within 24 hours of birth and continued for 7 days and 2 Control group in whom therapeutic phototherapy was started considering serum bilirubin level and other clinical condi­tions as per institutional guidelines. Mean value of total serum bilirubin (TSB, duration of phototherapy, the need for exchange transfusion and duration of hospital stay in both groups were analyzed.Results: The maximum mean TSB level in prophylactic group was observed on 7th day and in control group it was observed on 3rd day of life. The total serum bilirubin levels were significantly lower in the 3rd and 5th days of life in the prophylactic group in comparison to control group (P value 0.001. Total serum bilirubin level exceeded therapeutic

Purpose: To determine the effect of prophylactic gastrostomy tube (GT) placement on acute and long-term outcome for patients treated with definitive chemoradiotherapy for locally advanced head and neck cancer. Methods and Materials: One hundred twenty consecutive patients were treated with chemoradiotherapy for Stage III/IV head and neck cancer to a median dose of 70 Gy (range, 64-74 Gy). The most common primary site was the oropharynx (66 patients). Sixty-seven patients (56%) were treated using intensity-modulated radiotherapy (IMRT). Seventy patients (58%) received prophylactic GT placement at the discretion of the physician before initiation of chemoradiotherapy. Results: Prophylactic GT placement significantly reduced weight loss during radiation therapy from 43 pounds (range, 0 to 76 pounds) to 19 pounds (range, 0 to 51 pounds), which corresponded to a net change of -14% (range, 0% to -30%) and -8% (range, +1% to -22%) from baseline, respectively (p < 0.001). However, the proportion of patients who were GT-dependent at 6- and 12-months after treatment was 41% and 21%, respectively, compared with 8% and 0%, respectively, for those with and without prophylactic GT (p < 0.001). Additionally, prophylactic GT was associated with a significantly higher incidence of late esophageal stricture compared with those who did not have prophylactic GT (30% vs. 6%, p < 0.001). Conclusions: Although prophylactic GT placement was effective at preventing acute weight loss and the need for intravenous hydration, it was also associated with significantly higher rates of late esophageal toxicity. The benefits of this strategy must be balanced with the risks.

Full Text Available Prophylactic antipyretic administration decreases the post-vaccination adverse reactions. Recent study finds that they may also decrease the antibody responses to several vaccine antigens. This systematic review aimed to assess the evidence for a relationship between prophylactic antipyretic administration, post-vaccination adverse events, and antibody response in children.A systematic search of major databases including MEDLINE and EMBASE was carried out till March 2014. Randomized controlled trials (RCTs comparing prophylactic antipyretic treatment versus placebo post-vaccination in children ≤ 6 years of age were included. Two reviewers independently applied eligibility criteria, assessed the studies for methodological quality, and extracted data [PROSPERO registration: CRD42014009717].Of 2579 citations retrieved, a total of 13 RCTs including 5077 children were included in the review. Prophylactic antipyretic administration significantly reduced the febrile reactions (≥ 38.0 °C after primary and booster vaccinations. Though there were statistically significant differences in the antibody responses between the two groups, the prophylactic PCM group had what would be considered protective levels of antibodies to all of the antigens given after the primary and booster vaccinations. No significant difference in the nasopharyngeal carriage rates (short-term and long-term of H. influenzae or S. pneumoniae serotypes was found between the prophylactic and no prophylactic PCM group. There was a significant reduction in the local and systemic symptoms after primary, but not booster vaccinations.Though prophylactic antipyretic administration leads to relief of the local and systemic symptoms after primary vaccinations, there is a reduction in antibody responses to some vaccine antigens without any effect on the nasopharyngeal carriage rates of S. pneumoniae & H. influenza serotypes. Future trials and surveillance programs should also aim at

Drug treatment can defer surgical intervention in benign prostatic hyperplasia (BPH), a common disorder in elderly men, and is widely practiced. Various herbal formulations have been used for the treatment of BPH, but few have been compared with established modern medicines in head-to-head clinical trials. We compared the effectiveness and tolerability of an oral formulation, comprising standardized extracts of Murraya koenigii and Tribulus terrestris leaves being marketed in India under Ayurvedic license, versus tamsulosin in the treatment of symptomatic BPH. A double-blind, double-dummy, parallel-group, randomized controlled trial was conducted with treatment-naive ambulatory patients with BPH aged >50 years. Patients received either the plant drug in a dose of 2 capsules BID or tamsulosin 400 μg once daily for 12 weeks with 2 interim follow-up visits at the end of 4 and 8 weeks. The double-dummy technique was used to ensure double-blinding. The primary effectiveness measure was reduction in the International Prostate Symptom Score (IPSS). Proportion of patients becoming completely or relatively symptom free (IPSS terrestris-based formulation significantly lowered IPSS scores in the initial treatment of symptomatic BPH. Further trials are needed to determine if the beneficial effect is sustained beyond the 12-week observation period of this trial. Copyright © 2011 Elsevier HS Journals, Inc. All rights reserved.

Breast cancer is the most common oncologic disease in the female population. Besides the sporadic occurrence, it occurs in the familial or hereditary form. Genetic testing for mutation BRCA1 and BRCA2 helps to identify women, who are at increased risk of developing breast and ovarian cancer. Women with the hereditary form of breast cancer occurs in 5 -10%. Women with mutations BRCA1 and BRCA2 have to be classified to intensive dispensaration, and may consider several options for breast cancer prevention, as prophylactic mastectomy, prophylactic salpingo-oophorectomy or chemo prevention.

To explore the decision-making process of women with a BRCA1 or BRCA2 gene mutation who have chosen to undergo prophylactic mastectomy. Cross-sectional, qualitative, descriptive design. Participants were recruited from an outpatient cancer prevention center in the oncology and medical genetics departments of a large university-affiliated hospital in Montreal, Quebec, Canada. 10 women carrying a BRCA1 or BRCA2 mutation; 8 previously had had a prophylactic mastectomy and 2 were scheduled for surgery at the time of study. Semistructured, in-depth interviews were conducted. Field notes were written and audiotapes were transcribed verbatim. The textual data were coded and analyzed. Decision-making process for prophylactic mastectomy. Two broad findings emerged. First, several intrapersonal and contextual factors interacted throughout the process to move women either closer to choosing a prophylactic mastectomy or further from the decision. Second, all women reported experiencing a "pivotal point," an emotionally charged event when the decision to have a prophylactic mastectomy became definitive. Pivotal points for patients included either receiving a positive result for a genetic mutation or a breast cancer diagnosis for herself or a family member in the context of positive mutation status. Decision making about prophylactic mastectomy was an affective and intuitive process incorporating contexts and their relations rather than a rational, straight-forward process of weighing pros and cons. Supportive interventions for women in this population should explicitly address the individual and the inter-relationships of contextual factors that shape decision making about prophylactic mastectomy while recognizing important affective components involved.

Short-term trials have demonstrated the efficacy and safety of combination therapy using antimuscarinics and α-blockers in men with lower urinary tract symptoms (LUTS). The Study of Solifenacin Succinate and Tamsulosin Hydrochloride OCAS (oral controlled absorption system) in Males with Lower Urinary Tract Symptoms (NEPTUNE) II is the first long-term study using solifenacin (Soli) and the oral controlled absorption system formulation of tamsulosin (TOCAS). To evaluate long-term (up to 52 wk) safety and efficacy of flexible dosing of two fixed-dose combinations (FDC) of Soli plus TOCAS in men with moderate to severe storage symptoms and voiding symptoms. Patients with both storage and voiding LUTS, maximum urinary flow rate of 4.0-12.0 ml/s, prostate size storage and voiding subscores, micturition diary variables, and quality of life parameters. In all, 1066 men completed NEPTUNE and received one dose or more of study medication in NEPTUNE II. Treatment-emergent adverse events were reported in 499 (46.8%) patients who participated in NEPTUNE II; most were mild or moderate. Urinary retention occurred in 13 of 1208 (1.1%) patients receiving one or more FDCs in NEPTUNE and/or NEPTUNE II; 8 (0.7%) required catheterisation (acute urinary retention [AUR]). Reductions in total IPSS and TUFS during NEPTUNE were maintained for up to 52 wk of FDC treatment, with mean reductions of 9.0 (standard deviation [SD]: 5.7) and 10.1 (SD: 9.2), respectively, from baseline to end of treatment. Clinically relevant improvements were also observed for secondary efficacy end points. Long-term treatment with FDC Soli plus TOCAS was well tolerated and efficacious in men with storage and voiding LUTS, with a low incidence of AUR. Treatment with solifenacin plus tamsulosin in a fixed-dose combination tablet was well tolerated by men with lower urinary tract symptoms. Improvements in symptoms were achieved after 4 wk of treatment, with further improvements at week 16 maintained for up to 52 wk

Full Text Available The aim of the present study was to develop tamsulosin hydrochloride sustained-release pellets using two-layered membrane techniques. Centrifugal granulator and fluidized-bed coater were employed to prepare drug-loaded pellets and to employ two-layered membrane coating respectively. The prepared pellets were evaluated for physicochemical characterization, subjected to differential scanning calorimetry (DSC and in vitro release of different pH. Different release models and scanning electron microscopy (SEM were utilized to analyze the release mechanism of Harnual® and home-made pellets. By comparing the dissolution profiles, the ratio and coating weight gain of Eudragit® NE30D and Eudragit® L30D55 which constitute the inside membrane were identified as 18:1 and 10%–11%. The coating amount of outside membrane containing Eudragit® L30D55 was determined to be 0.8%. The similarity factors (f2 of home-made capsule and commercially available product (Harnual® were above 50 in different dissolution media. DSC studies confirmed that drug and excipients had good compatibility and SEM photographs showed the similarities and differences of coating surface between Harnual® and self-made pellets before and after dissolution. According to Ritger-Peppas model, the two dosage form had different release mechanism.

To evaluate the safety and efficacy of prophylactic uterine artery embolization (UAE) before obstetrical procedures with high risk for massive bleeding. A retrospective review of 29 female patients who underwent prophylactic UAE from June 2009 to February 2014 was performed. Indications for prophylactic UAE were as follows: dilatation and curettage (D and C) associated with ectopic pregnancy (cesarean scar pregnancy, n = 9; cervical pregnancy, n = 6), termination of pregnancy with abnormal placentation (placenta previa, n = 8), D and C for retained placenta with vascularity (n = 5), and D and C for suspected gestational trophoblastic disease (n = 1). Their medical records were reviewed to evaluate the safety and efficacy of UAE. All women received successful bilateral prophylactic UAE followed by D and C with preservation of the uterus. In all patients, UAE followed by obstetrical procedure prevented significant vaginal bleeding on gynecologic examination. There was no major complication related to UAE. Vaginal spotting continued for 3 months in three cases. Although oligomenorrhea continued for six months in one patient, normal menstruation resumed in all patients afterwards. During follow-up, four had subsequent successful natural pregnancies. Spontaneous abortion occurred in one of them during the first trimester. Prophylactic UAE before an obstetrical procedure in patients with high risk of bleeding or symptomatic bleeding may be a safe and effective way to manage or prevent serious bleeding, especially for women who wish to preserve their fertility

Two prospective trials have demonstrated prophylactic antimuscarinics following prostatectomy reduce pain from bladder spasms. Our practice adopted the routine administration of prophylactic belladonna and opium (B&O) suppositories to patients undergoing robotic assisted laparoscopic radical prostatectomy (RALP). The aim of this study is to determine if this change in clinical practice was associated with improvement of postoperative outcomes. The medical records of 202 patients that underwent RALP surgery who were or were not administered prophylactic B&O suppositories in the immediate postoperative period were abstracted for duration of anesthesia recovery, pain and analgesic use. Patient and surgical characteristics between groups were similar except B&O group were slightly older (p = 0.04) and administered less opioid analgesics (p = 0.05). There was no difference between groups in the duration of phase I recovery from anesthesia (p = 0.96). Multivariable adjustments for age, body mass index, American Society of Anesthesiologists physical status, and surgical duration were made, and again it was found that suppository administration had no association with phase I recovery times (p = 0.94). The use of antimuscarinic medication for bladder spams in the B&O group was less during phase I recovery (p suppositories at the immediate conclusion of RALP surgery was not associated with improvements of the postoperative course.

To describe the benefits and optimum use of prophylactic antibiotics in users of therapeutic contact lenses (TCL). A microbiological study was carried out on samples from 33 patients who continuously wore TCL. The resistance to antibiotics of bacteria isolated in our health region was also reviewed. An assessment was also made on whether there were microorganisms of a higher pathogenic potential in TCL than conventional contact lenses, as reported in the literature. No bacteria were isolated from 17 (52%) of the 33 lenses studied. From the 16 (48%) remaining lenses, coagulase negative Staphylococci were isolated from 10 (62%), Propionibacterium acnes from 4 (25%), and Corynebacterium from 2 (13%). The high number of negative cultures and the presence of saprophytic bacteria indicate that prophylactic antibiotic treatment is not precise. The most frequent pathogenic bacteria found in contact lenses are strongly resistant to the current commercially available antibiotics. Copyright © 2012 Sociedad Española de Oftalmología.

Efficacy of prophylactic irradiation in altering renal allograft survival

International Nuclear Information System (INIS)

Faber, R.; Johnson, H.K.; Braren, H.V.; Richie, R.E.

1974-01-01

Renal allograft rejection is a complex phenomenon involving both cell-mediated and humoral antibody responses. Most transplant programs have used a combination of therapeutic modalites to combat the immune system in an attempt to prolong both allograft and patient survival. Corticosteroids (methylprednisolone (Solu-Medrol) and prednisone and azathioprine (Imuran) are widely accepted as immunosuppressive drugs; however, both are non-specific and have the disadvantage of compromising the recipients' defense mechanisms. Nevertheless, these drugs have proved to be essential to the success of renal transplantation and they are routinely used while the efficacy of other modalities continues to be evaluated. We could find no reports of a prospective study to evaluate the efficacy of prophylactic irradiation in the complex therapeutic situation of renal transplantation with the only variable being the administration of local graft irradiation. The purpose of this study was to evaluate prophylactic graft irradiation for its effectiveness in preventing graft rejection in conjunction with Imuran and corticosteroids

Primary membranous nephropathy is associated with increased risk of venous thromboembolic events, which are inversely correlated with serum albumin levels. To evaluate the potential benefit of prophylactic anticoagulation (venous thromboembolic events prevented) relative to the risk (major bleeds), we constructed a Markov decision model. The venous thromboembolic event risk according to serum albumin was obtained from an inception cohort of 898 patients with primary membranous nephropathy. Risk estimates of hemorrhage were obtained from a systematic literature review. Benefit-to-risk ratios were predicted according to bleeding risk and serum albumin. This ratio increased with worsening hypoalbuminemia from 4.5:1 for an albumin under 3 g/dl to 13.1:1 for an albumin under 2 g/dl in patients at low bleeding risk. Patients at intermediate bleeding risk with an albumin under 2 g/dl have a moderately favorable benefit-to-risk ratio (under 5:1). Patients at high bleeding risk are unlikely to benefit from prophylactic anticoagulation regardless of albuminemia. Probabilistic sensitivity analysis, to account for uncertainty in risk estimates, confirmed these trends. From these data, we constructed a tool to estimate the likelihood of benefit based on an individual’s bleeding risk profile, serum albumin level, and acceptable benefit-to-risk ratio (http://www.gntools.com). This tool provides an approach to the decision of prophylactic anticoagulation personalized to the individual’s needs and adaptable to dynamic changes in health status and risk profile.

A 12 year-old girl was treated with prophylactic cranial irradiation for acute lymphoblastic leukaemia (ALL). At the age of 39, she was admitted to our hospital for status epilepticus. Computed tomography demonstrated two, enhancing bilateral sided intracranial tumors. After surgery, this patient presented meningiomas which histologically, were of the meningothelial type. The high cure rate in childhood ALL, attributable to aggressive chemotherapy and prophylactic cranial irradiation, is capable of inducing secondary brain tumor. Twelve cases of high-dose radiation-induced meningioma following ALL are also reviewed. (author)

The purpose of this prospective, randomized, double-blind, placebo-controlled study was to determine the effect of prophylactic amoxicillin on the occurrence of endodontic flare-up in asymptomatic, necrotic teeth. Seventy patients participated and had a clinical diagnosis of an asymptomatic, necrotic tooth with associated periapical radiolucency. One hour before endodontic treatment, patients randomly received either 3 g of amoxicillin or 3 g of a placebo control in a double-blind manner. After endodontic treatment, each patient received: ibuprofen; acetaminophen with codeine (30 mg); and a 5 1/2-day diary to record pain, swelling, percussion pain, and number and type of pain medication taken. The results demonstrated 10% of the 70 patients had a flare-up characterized by moderate-to-severe postoperative pain or swelling that began approximately 30 h after endodontic treatment and persisted for an average of 74 h. Of the seven patients who had flare-ups, 4 were in the amoxicillin group and 3 were not. Prophylactic amoxicillin did not significantly (p = 0.80) influence the endodontic flare-up. We concluded that a prophylactic dose of amoxicillin before endodontic treatment of asymptomatic, necrotic teeth had no effect on the endodontic flare-up.

Full Text Available Objectives: The aim of this review was to systematically examine the available evidence for the effectiveness of prophylactic antibiotics in cases of vesicoureteric reflux (VUR. Materials and Methods: We searched the relevant data on medical management of VUR and the date of last search was June 2008. The search included both randomized controlled trials as well as the nonrandomized trials and the data sources were; MEDLINE, online peer reviewed journals, Cochrane database and abstracts from conference proceedings. Results: Barring few most of the studies published on medical management were nonrandomized. Besides being small in number many of these studies were of poor-quality and poorly designed eventually failing in giving a reliable answer in this regard. Few of the studies suggest that the children with low grade VUR might do well even without antibiotic prophylaxis. Conclusions : In the absence of properly designed, randomized controlled trials and long-term follow-up the question of antibiotic prophylaxis in cases of VUR remains unanswered in large part of it. Whether to give prophylactic antibiotics or not would ultimately need a shared decision-making involving both the treating physician and the parents assessing both the risks and the benefits.

The consistency of the classification of prophylactic antiradiation drugs have been given consideration as history of their discovery, theory of the radioprotection mechanisms and their use in applied medicine. Prophylactic drugs consists of radioprotectors with short-term of long-term action, drugs stimulating radioresistance, the ones suppressing symptoms of primary radiation reaction, the ones of early detoxication, the ones for adsorption and elimination of radionuclides from an organism [ru

The optimal antibiotic prophylaxis for pediatric shunt-related procedures is not clear. There is much inconsistency among different medical centers. This paper summarizes and analyzes the various prophylactic antibiotic regiments used for shunt-related surgeries at different pediatric neurosurgery centers in the world. A survey questionnaire was distributed through the Pediatric Neurosurgery list-server (an e-mail-based special interest group in pediatric neurosurgery). Forty-five completed questionnaires were received, one per medical center, primarily from pediatric neurosurgeons with the following geographic breakdown: 25 from North America, 13 from Europe, and 7 from Asia and other countries. All centers routinely administered prophylactic antibiotics for shunt-related procedures. The drugs of choice were first-generation cephalosporins (23), second-generation cephalosporins (10), naficillin/oxacillin (4), vancomycin (3), clindamycin (1), amoxicillin (1), and mixed protocols in three centers. The initial drug administration ("first dose") was: in the department before transfer to operating room (5), upon arrival to operating room (11), at induction of anesthesia (13), and at initial skin incision (16). The duration of antibiotic dosage also varied: single dose (13), 24-h administration (26), 48-h administration (2), and longer than 48 h in four centers. Two general tendencies were noted, common to the majority of participating centers. There was a general trend to modify antibiotic treatment protocol in "high-risk" populations. The second common theme noted in more than half of responding centers was the use of long-term antibiotic treatment for externalized devices (such as externalized shunts, external ventricular drains or lumbar drains), usually till the device was in place.

There has been renewal of interest in the use of prophylactic antibiotics to reduce the frequency of exacerbations and improve quality of life in chronic obstructive pulmonary disease (COPD). To determine whether or not regular treatment of COPD patients with prophylactic antibiotics reduces exacerbations or affects quality of life. We searched the Cochrane Airways Group Trials Register and bibliographies of relevant studies. The latest literature search was August 2013. Randomised controlled trials (RCTs) that compared prophylactic antibiotics with placebo in patients with COPD. We used the standard methods of The Cochrane Collaboration. Data were extracted and analysed by two independent review authors. Seven RCTs involving 3170 patients were included in this systematic review. All studies were published between 2001 and 2011. Five studies were of continuous antibiotics and two studies were of intermittent antibiotic prophylaxis (termed 'pulsed' for this review). The antibiotics investigated were azithromycin, erythromycin, clarithromycin and moxifloxacin. Azithromycin, erythromycin and clarithromycin are macrolides while moxifloxacin is a fourth-generation synthetic fluoroquinolone antibacterial agent. The study duration varied from three months to 36 months and all used intention-to-treat analysis. Most of the results were of moderate quality. The risk of bias of the included studies was generally low, and we did not downgrade the quality of evidence for risk of bias.The trials recruited participants with a mean age of 66 years and with at least a moderate severity of COPD. Three trials included participants with frequent exacerbations and two trials recruited participants requiring systemic steroids or antibiotics, or both, or who were at the end stage of their disease and required oxygen.The primary outcomes for this review were the number of exacerbations and quality of life.With use of continuous prophylactic antibiotics the number of patients experiencing

Migraine - Prophylactic Treatment

Full Text Available Preventive therapy in migraine constitutes an important aspect of migraine management especially in patients who are not controlled or have significant disability despite taking drugs for acute management. In spite of te recent advances in understanding of the pathophysiology of migraine, the mechanisms of action of many preventive drugs are largely unknown. Further, these provide only about 50% reduction in frequency in about 2/3rds of migraine sufferers. Hence, risk-benefit ratio must be considered while prescribing these agents. Recent efforts to undertake large-scale meta-analysis to assess the efficacy of these agents have been rewarding and consensus guidelines have evolved. Propanolol, metoprolol, amitriptyline, sodium valproate, flunarizine and lisuride have emerged as first line drugs. The role of newer anti-convulsants and botox injections in refractory cases are being investigated. Availability, co-morbidities, medical contraindications, concomitant acute therapy and costs are important determinants for choosing a particular agent. This article reviews the guidelines to be followed in choosing the prophylactic treatment options for migraine.

This study was undertaken to investigate the hemodynamic effect of prophylactic digitalization before major surgical procedures. Sixteen patients, all admitted for an elective vascular operation for arteriosclerotic disease and all with impaired left ventricular function, were investigated. In half of the patients, digitalis was given before the operation, the other half of the patients served as the control study. The measured parameters were pulmonary artery mean pressure, pulmonary capillary wedge pressure, central venous pressure, mean arterial blood pressure, heart rate, cardiac output, blood volume and arterial, as well as venous, oxygen content. Preoperatively, before digitalization, no significant differences were noted between the two groups at rest and during exercise. Before anesthesia and postoperatively, those given digitalis had improved cardiac function. Those in both groups, however, had a normal hemodynamic response to the surgical trauma. In this study, a definite answer is not provided concerning the usefulness of prophylactic digitalization but an increase in the ability of the digitalized heart to withstand the imposition of a pressure load postoperatively is suggested.

The SMART trial is a UK-based, multicentre RCT comparing prophylactic radiotherapy and symptom-based (deferred) radiotherapy in 203 patients with Malignant Pleural Mesothelioma who had undergone large bore pleural interventions. Using costs and quality of life data collected alongside the clinical trial, we will estimate the cost-effectiveness of prophylactic radiotherapy compared to deferred radiotherapy over a 1-year period. Healthcare utilization and costs were captured during the trial. Utility weights produced by the EQ-5D questionnaire were used to determine quality-adjusted life-years (QALY) gained. The incremental cost-effectiveness ratio was calculated over the one-year trial period. Costs were similar in the immediate and deferred radiotherapy groups: £5480.40 (SD = £7040; n = 102) and £5461.40 (SD = £7770; n = 101) respectively. There was also no difference in QALY: 0.498 (95% CI: [0.45, 0.547]) in the prophylactic radiotherapy group versus 0.525 (95% CI: [0.471, 0.580]) in the deferred group. At a willingness to pay threshold of £30,000/QALY there was only a 24% chance that prophylactic radiotherapy was cost-effective compared to deferred radiotherapy. There was no significant effect of prophylactic radiotherapy on quality of life in the intervention group, nor was there any discernable decrease in healthcare costs. There is little evidence to suggest that prophylactic radiotherapy is a cost-effective intervention in this population. ISRCTN72767336 with ISRCTN.

Pesonen, Luke O; Halloran, Brian G; Aziz, Abdulhameed

2018-01-01

Vascular groin wounds have higher than expected surgical site infection (SSI) rates and some patients are at enhanced risk. The Wiseman et al. paper suggests an objective scoring system that identifies patients at enhanced risk of postdischarge SSI. We hypothesize that prophylactic groin wound vacuum-assisted closure (VAC) therapy in enhanced risk patients will decrease SSI and readmission and the Wiseman model provides potential evidence that enhanced risk patients can be objectively identified. A single institution, retrospective analysis was conducted from January 2013 to September 2016 utilizing procedure codes to identify patients with wound VACs placed in the operating room. Two distinct groups were identified. The first was a wound complication patient group with 15 limbs (13 patients) with a groin wound VAC placed within 45 days postoperatively for groin wound complications. Eleven of these limbs had the VAC placed at readmission. The second group was a prophylactic patient group that included 8 limbs (7 patients) who received a VAC prophylactically placed in the enhanced risk wounds. These wounds were determined to be enhanced risk based on clinical criteria judged by the operating surgeon such as a large overhanging panniculus and/or one of several ongoing medical issues. We calculated a Wiseman score for all patients, determined total cost of the readmissions, and determined 30-day postsurgical SSI incidence for the prophylactic VAC group. Per the Wiseman scores, 9 limbs with postoperative complications were high risk and 3 limbs were moderate/high risk. Eleven limbs had a VAC placed at readmission with an average readmission cost of $8876.77. For the prophylactic group, 8 limbs were high risk with no observed postdischarge SSI in the first 30 days from surgery. The Wiseman scores showed close correlation between the retrospective high and moderate/high risk groups versus the prophylactic VAC group (31.5 ± 7.3 vs. 32 ± 5.5, P = 0.87). The Wiseman

Full Text Available In competitive and constantly changing market conditions special attention has been paid to market researches. The results of these studies become the basis for formation of sales estimates, and projected levels of revenues and profits from sales. Market researches are the essential condition to make offered goods successful at the market. It is market researches that help companies to realize the control of consumers' needs changing. The market researches on demand for dietary and prophylactic nutrition in the Saratov Region have been the research objective. In accordance with the given objective the following goals have been formed: 1 finding out the most spread diseases among the population; 2 determination of the average age of people suffering from one or another disease; 3 studying demand of products with food fiber additives; 4 analysis of respondent's preference regarding the addition of natural vegetable additives to foodstuff; 5 demand for dietary and prophylactic foodstuff among the population. Since the survey has been carried out among people suffering from various diseases, particular attention during the market research has been turned to the medical and prophylactic properties of food fibers to find out the attitude of the respondents to functional foodstuff. The dynamics of noninfectious diseases, the population health status depending on age, and increase of overweight people during 2012–2014 have been shown. As a result of questionnaire data processing it has been ascertained that the population is of low awareness regarding the necessity to consume foodstuff with radioprotective and chelator properties. The researches have demonstrated that dietary and prophylactic foodstuff is in demand and consequently the development of such products is reasonable.

Evidence-based analysis of prophylactic treatment of asymptomatic retinal breaks and lattice degeneration.

Science.gov (United States)

Wilkinson, C P

2000-01-01

To assess the quality of information in the literature regarding the benefits of prophylactic treatment of asymptomatic retinal tears and lattice degeneration. Asymptomatic retinal breaks occur in approximately 7% of patients over age 40, and lattice degeneration is present in approximately 8% of the general population. Because retinal breaks cause retinal detachment and lattice degeneration is associated with approximately 30% of retinal detachments, prophylactic treatment of these lesions has sometimes been recommended. A panel of vitreoretinal experts performed a literature review of all publications regarding prevention of retinal detachment that have been published in English. These articles were then used to prepare recommendations for patient care in an American Academy of Ophthalmology Preferred Practice Pattern (PPP). Each recommendation was rated according to: (1) its importance in the care process and (2) the strength of evidence supporting the given recommendation. Most recommendations were rated as A (most important to patient care). Only a single publication was graded as I (providing strong evidence in support of a recommendation), and this was not a prospective trial. Of the few publications rated as II (substantial evidence), most were studies documenting a lack of treatment benefit. Because of an absence of level I and level II studies in the literature, level III (consensus of expert opinion) was the basis for most recommendations in the PPP. The current literature regarding prevention of retinal detachment does not provide sufficient information to support strongly prophylactic treatment of lesions other than symptomatic flap tears. Prospective randomized trials of prophylactic therapy are indicated. Eyes highly predisposed to retinal detachment should be considered for such studies.

Patients with head and neck carcinoma are often provided concurrent chemoradiotherapy (CCRT), but they experience severe mucositis and dysphagia. These side effects can lead to decreased oral intake, resulting in interruption of treatment. In our hospital, from September 2007, all patients with oropharyngeal cancer who were to receive CCRT, were principally offered percutaneous endoscopic gastrostomy (PEG) before the start of treatment, and tube feeding was started when swallowing became impaired, to accomplish the treatment as planned. To evaluate the effect of prophylactic PEG, outcome measures in this study included the frequency of unplanned break from CCRT, nutritional deterioration and required analgesic during CCRT, complication of PEG, and patient satisfaction between 15 patients with PEG and 11 patients without PEG as a control group. Although no significant weight loss occurred in either group, there were fewer patients with a Body Mass Index <18.5 in the PEG group after CCRT than in the control group. Regarding the treatment, most patients were satisfied with their PEG and considered that prophylactic PEG was necessary and helpful in completing the CCRT. This study suggests that prophylactic PEG helps patients to complete CCRT both mentally and nutritionally. (author)

1979-02-01

The success of prophylactic digitalization in reducing the incidence of supraventricular tachyarrhythmias (SVT) was studied in 140 randomly grouped, consecutive patients undergoing myocardial revascularization operations. The test group received either 1 or 1.5 mg. of digoxin the day before operation and were maintained postoperatively on 0.25 mg. of digoxin daily. There was a significant increase (p less than 0.05) in the incidence of SVT in the treated patients (17 of 61 or 27.8 percent) vs. the untreated patients (nine of 79 or 11.4 percent). There was no significant difference in SVT with the two digitalization dosage levels (31.6 percent with 1 mg. vs. 21.7 percent with 1.5 mg.). Prophylactic digitalization demonstrates no benefit in the prevention of SVT following myocardial revascularization and may, in fact, predispose the patient to these arrhythmias.

Controversy exists over the prophylactic treatment of predisposing lesions to prevent retinal detachment. Seven hundred sixty consecutive phakic fellow eyes with rhegmatogenous retinal detachment in the first eye were examined by the same vitreoretinal surgeon before detachment surgery and for a follow-up period ranging from 1 to 72 months, with a mean of 36 months. During this period, in 305 fellow eyes (40.1%) predisposing retinal lesions were present and prophylactic treatments (photocoagulation, cryotherapy or scleral buckle) were performed independently of vitreous status. The results were then compared with the incidence of bilateral RD without prophylaxis reported in Folk and Burton's study of 1982; the two study's data were well matched and showed no significant difference in regards to age, sex, incidence myopia > or =-2.5 and incidence of lattice degeneration. The objective was to investigate whether or not prophylactic treatment is able to avert retinal detachment in the fellow eye. The age of the patients with peripheral retinal lesions was correlated inversely with the presence of myopia. Nine eyes out of 305 eyes treated (2.9%) developed a retinal detachment, reducing the rate of bilateral retinal detachment to 1.2% (9 eyes out of 760). This incidence of bilaterality (1.2%) was lower than the incidence of retinal detachment in fellow eyes not prophylactically treated as reported in the literature, and there exists a highly statistically significant difference between this study's data of 1.2% after prophylaxis and a 13.4% rate of bilaterality as reported by Folk without prophylaxis (P=0.0000).

Anterior cruciate ligament (ACL) injuries commonly occur during landing maneuvers. Prophylactic knee braces were introduced to reduce the risk of ACL injuries, but their effectiveness is debated. We hypothesized that bracing would improve biomechanical factors previously related to the risk of ACL injuries, such as increased hip and knee flexion angles at initial contact and at peak vertical ground-reaction force (GRF), increased ankle plantar flexion angles at initial contact, decreased peak GRFs, and decreased peak knee extension moment. We also hypothesized that bracing would increase the negative power and work of the hip joint and would decrease the negative power and work of the knee and ankle joints. Controlled laboratory study. Three-dimensional motion and force plate data were collected from 8 female and 7 male recreational athletes performing double-leg drop landings from 0.30 m and 0.60 m with and without a prophylactic knee brace. GRFs, joint angles, moments, power, and work were calculated for each athlete with and without a knee brace. Prophylactic knee bracing increased the hip flexion angle at peak GRF by 5.56° (P knee flexion angle at peak GRF by 4.75° (P = .001), and peak hip extension moment by 0.44 N·m/kg (P knee and ankle. No differences in peak GRFs and peak knee extension moment were observed with bracing. The application of a prophylactic knee brace resulted in improvements in important biomechanical factors associated with the risk of ACL injuries. Prophylactic knee braces may help reduce the risk of noncontact knee injuries in recreational and professional athletes while playing sports. Further studies should investigate different types of prophylactic knee braces in conjunction with existing training interventions so that the sports medicine community can better assess the effectiveness of prophylactic knee bracing. © 2016 The Author(s).

E-mail: moises.vet@hotmail.com This paper aimed to assess the risk of exposure and conduct of prophylactic antirrabies treatment established by health care providers and the endemics Municipality of Garanhuns, PE during their professional activities. We conducted a descriptive epidemiological study of retrospective type, from data collection through the application of a semi-structured questionnaire containing open and closed questions, to 192 professionals, 168 health agents and 24 agents of the municipality of endemics Garanhuns -PE. Of the 192 interviewed agents, 14.1% (27/165 had been attacked by animals during their occupation activities. On the post-exposure prophylactic treatment, it was found that 44.5% (12/27 received-vaccination serum, 37% (10/27 did not undergo any treatment, while only 18.5% (5/27 had the wound washed with soap and water. Was concluded that there is a lack of basic information regarding both the pre-exposure or post-exposure prophylaxis of rabies in professionals like agents that act with both health and / or endemic diseases and it is suggested both the improvement of their professional skills as the preexposure immunization as prophylactic measure to minimize the occupational risk in function of their field activities.

To evaluate the effectiveness of intrapartum prophylactic amnioinfusion in pregnancies complicated by oligohydramnios. Randomized controlled trials of prophylactic amnioinfusion in women with oligohydramnios were identified using computerized databases, index reviews, and references cited in original studies and review articles. We evaluated, abstracted data from, and analyzed randomized studies of prophylactic intrapartum amnioinfusion in women with oligohydramnios. In every study the group allocation was based exclusively on presence of oligohydramnios. Only published studies with clearly documented outcome data were included. The quality of each trial was evaluated for methodology, inclusion and exclusion criteria, adequacy of randomization, amnioinfusion protocols, definition of outcomes, and statistical analyses. The trials were evaluated concerning cesarean deliveries for fetal heart rate (FHR) abnormalities, overall cesarean rates, acidemia at birth, intrapartum fetal heart rate abnormalities, Apgar scores under 7 at 5 minutes, and postpartum endometritis. Thirty-five studies were identified, of which 14 met the inclusion criteria for this systematic review. They included 1533 patients, 793 in the amnioinfusion group, and 740 controls. Odds ratios (OR) with their 95% confidence intervals (CI) for each outcome were calculated. We calculated an estimate of the OR and risk difference for dichotomous outcomes using random and fixed-effects models. A test of homogeneity was done across studies. Women with oligohydramnios who received intrapartum amnioinfusion had lower incidence of cesarean for FHR abnormalities (OR 0.23; 95% CI 0.15, 0.35). Intrapartum amnioinfusion also was associated with lower overall rates of cesarean deliveries (OR 0.52; 95% CI 0.40, 0. 68), acidemia at birth (OR 0.40; 95% CI 0.30, 0.55), FHR abnormalities during labor (OR 0.24; 95% CI 0.17, 0.34), and Apgar scores under 7 at 5 minutes (OR 0.52; 95% CI 0.29, 0.91).

Globally, tobacco use causes approximately 6 million deaths per year, and predictions report that with current trends; more than 8 million deaths are expected annually by 2030. Cigarette smokings is currently accountable for more than 480,000 deaths each year in United States (US) and is the leading cause of preventable death in the US. On average, smokers die 10 years earlier than nonsmokers and if smoking continues at its current proportion among adolescents, one in every 13 Americans aged 17 years or younger is expected to die prematurely from a smoking-related illness. Even though there has been a marginal smoking decline of around 5% in recent years (2005 vs 2015), smokers still account for 15% of the US adult population. What is also concerning is that 41,000 out of 480,000 deaths results from secondhand smoke (SHS) exposure. Herein, we provide a detailed review of health complications and major pathological mechanisms including mutation, inflammation, oxidative stress, and hemodynamic and plasma protein changes associated with chronic smoking. Further, we discuss prophylactic interventions and associated benefits and provide a rationale for the scope of clinical treatment. Considering these premises, it is evident that much detailed translational and clinical studies are needed. Factors such as the length of smoking cessation for ex-smokers, the level of smoke exposure in case of SHS, pre-established health conditions, genetics (and epigenetics modification caused by chronic smoking) are few of the criteria that need to be evaluated to begin assessing the prophylactic and/or therapeutic impact of treatments aimed at chronic and former smokers (especially early stage ex-smokers) including those frequently subjected to second hand tobacco smoke exposure. Herein, we provide a detailed review of health complications and major pathological mechanisms including mutation, inflammation, oxidative stress, and hemodynamic and plasma protein changes associated with

Full Text Available Introduction. Sentinel lymph node biopsy in prophylactic mastectomy is controversial. It avoids lymphadenectomy in occult carcinoma but is associated with increased morbidity. Women with BRCA mutations have a higher incidence of occult carcinoma and our objective was to assess the clinical utility of sentinel lymph node biopsy when these women undergo prophylactic mastectomy. Materials and Methods. Seven-year retrospective consecutive case-series study of women, with a BRCA deleterious mutation, admitted to prophylactic mastectomy, at our center. Breast MRI < 6 months before surgery was routine, unless contraindicated. Results. Fifty-seven patients (43% BRCA1; 57% BRCA2 underwent 80 prophylactic mastectomies. 72% of patients had had breast cancer treated before prophylactic mastectomy or synchronously to it. The occult carcinoma incidence was 5%, and half of the cases were invasive. SLNB was performed in 19% of the prophylactic mastectomies; none of these had tumor invasion. Women with invasive carcinoma who had not undergone sentinel lymph node biopsy were followed closely with axillary ultrasound. The median follow-up was 37 months, with no local recurrence; 1 patient died of primary tumor systemic relapse. Conclusions. Our data do not support this procedure for routine (in agreement with previous literature, in this high risk for occult carcinoma population.

The monitoring of antimicrobial use is an essential step to control the selection and spread of antimicrobial resistance. Between January and October 2010 data on prophylactic and metaphylactic antimicrobial use were collected retrospectively on 50 closed or semi-closed pig herds. Ninety-three percent of the group treatments were prophylactic whereas only 7% were methaphylactic. The most frequently used antimicrobials orally applied at group level were colistin (30.7%), amoxicillin (30.0%), trimethoprim-sulfonamides (13.1%), doxycycline (9.9%) and tylosin (8.1%). The most frequently applied injectable antimicrobials were tulathromycin (45.0%), long acting ceftiofur (40.1%) and long acting amoxicillin (8.4%). The treatment incidences (TI) based on the used daily dose pig (UDD(pig) or the actually administered dose per day per kg pig of a drug) for all oral and injectable antimicrobial drugs was on average 200.7 per 1000 pigs at risk per day (min=0, max=699.0), while the TI based on the animal daily dose pig (ADD(pig) or the national defined average maintenance dose per day per kg pig of a drug used for its main indication) was slightly higher (average=235.8, min=0, max=1322.1). This indicates that in reality fewer pigs were treated with the same amount of antimicrobials than theoretically possible. Injectable products were generally overdosed (79.5%), whereas oral treatments were often underdosed (47.3%). In conclusion, this study shows that prophylactic group treatment was applied in 98% of the visited herds and often includes the use of critically important and broad-spectrum antimicrobials. In Belgium, the guidelines for prudent use of antimicrobials are not yet implemented. Copyright © 2012 Elsevier B.V. All rights reserved.

Introduction Continuous ambulatory peritoneal dialysis (CAPD) peritonitis may develop after endoscopic procedures, and the benefit of prophylactic antibiotics is unclear. In the present study, we investigated whether prophylactic antibiotics reduce the incidence of peritonitis in these patients. Patients and methods We retrospectively reviewed all endoscopic procedures, including esophagogastroduodenoscopy (EGD), colonoscopy, sigmoidoscopy, cystoscopy, hysteroscopy, and hysteroscopy-assisted intrauterine device (IUD) implantation/removal, performed in CAPD patients at Chang Gung Memorial Hospital, Taiwan, between February 2001 and February 2012. Results Four hundred and thirty-three patients were enrolled, and 125 endoscopies were performed in 45 patients. Eight (6.4%) peritonitis episodes developed after the examination. Antibiotics were used in 26 procedures, and none of the patients had peritonitis (0% vs. 8.1% without antibiotic use; p = 0.20). The peritonitis rate was significantly higher in the non-EGD group than in the EGD group (15.9% [7/44] vs. 1.2% [1/81]; pperitonitis rate compared to that without antibiotic use (0% [0/16] vs. 25% [7/28]; pPeritonitis only occurred if invasive procedures were performed, such as biopsy, polypectomy, or IUD implantation, (noninvasive procedures, 0% [0/20] vs. invasive procedures, 30.4% [7/23]; pperitonitis was noted if antibiotics were used prior to examination with invasive procedures (0% [0/10] vs. 53.8% [7/13] without antibiotic use; pperitonitis (antibiotics, 0% [0/4] vs. no antibiotics, 55.6% [5/9]; p = 0.10). Conclusion Antibiotic prophylaxis significantly reduced endoscopy-associated PD peritonitis in the non-EGD group. Endoscopically assisted invasive procedures, such as biopsy, polypectomy, IUD implantation/removal, and dilatation and curettage (D&C), pose a high risk for peritonitis. Prophylactic antibiotics for peritonitis prevention may be required in colonoscopic procedures and gynecologic procedures

This study was undertaken to determine whether 400 mg of prophylactic ibuprofen can alleviate pain from insertion of an intrauterine device (IUD) and to measure level of pain with improved techniques. We conducted a randomized, double-blind, placebo-controlled trial of 2019 first-time IUD users: 1008 women received placebo and 1011 women received 400 mg of ibuprofen. Participants took the single tablet at least 45 minutes before IUD insertion. Immediately after insertion, participants recorded level of pain by using a 10-cm visual analog scale, with the value of 10 meaning "worst imaginable pain." Median level of pain was 1.0 for both ibuprofen and placebo participants; rank test statistics confirmed no difference. Some subgroups of women experienced higher pain (eg, nulliparous women), but ibuprofen still had no important impact on level of pain. Even among first-time users, pain from IUD insertion is generally low. Prophylactic ibuprofen as used in this protocol does not reduce IUD insertion pain.

Hypoperfusion-induced thrombosis is an important mechanism for postsurgery stroke and cognitive decline, but there are no perioperative neuroprotectants to date. This study investigated whether prophylactic application of Edaravone, a free radical scavenger already used in treating ischemic stroke in Japan, can prevent infarct and cognitive deficits in a murine model of transient cerebral hypoxia-ischemia. Adult male C57BL/6 mice were subjected to transient hypoxic-ischemic (tHI) insult that consists of 30-minute occlusion of the unilateral common carotid artery and exposure to 7.5% oxygen. Edaravone or saline was prophylactically applied to compare their effects on cortical oxygen saturation, blood flow, coagulation, oxidative stress, metabolites, and learning-memory using methods that include photoacoustic imaging, laser speckle contrast imaging, solid-state NMR, and Morris water maze. The effects on infarct size by Edaravone application at different time points after tHI were also compared. Prophylactic administration of Edaravone (4.5 mg/kg×2, IP, 1 hour before and 1 hour after tHI) improved vascular reperfusion, oxygen saturation, and the maintenance of brain metabolites, reducing oxidative stress, thrombosis, white-matter injury, and learning impairment after tHI insult. Delayed Edaravone treatment after 3 h post-tHI became unable to reduce infarct size. Acute application of Edaravone may be a useful strategy to prevent postsurgery stroke and cognitive impairment, especially in patients with severe carotid stenosis. © 2015 American Heart Association, Inc.

Full Text Available Studies in patients and chimpanzees that spontaneously clear Hepatitis C Virus (HCV have demonstrated that natural immunity to the virus is induced during primary infections and that this immunity can be cross protective. These discoveries led to optimism regarding prophylactic HCV vaccines and a number of studies in the chimpanzee model have been performed, all of which resulted in modified infections after challenge but did not always prevent persistence of the virus. Therapeutic vaccine strategies have also been pursued in an effort to reduce the costs and side effects associated with anti-viral drug treatment. This review summarizes the studies performed thus far in both patients and chimpanzees for prophylactic and therapeutic vaccination, assesses the progress made and future perspectives.

Approximately 80% of cervical cancer cases occur in developing countries. In Thailand, cervical cancer has been the leading cancer in females, with an incidence of 24.7 cases per 100,000 individuals per year. We constructed a decision model to simulate the lifetime economic impact for women in the context of human papillomavirus (HPV) infection prevention. HPV-related diseases were of interest: cervical cancer, cervical intraepithelial neoplasia, and genital warts. The two strategies used were 1) current practice and 2) prophylactic quadrivalent vaccine against HPV types 6, 11, 16, and 18. We developed a Markov simulation model to evaluate the incremental cost-effectiveness ratio of prophylactic HPV vaccine. Women transition through a model either healthy or developing HPV or its related diseases, or die from cervical cancer or from other causes according to transitional probabilities under the Thai health-care context. Costs from a provider perspective were obtained from King Chulalongkorn Memorial Hospital. Costs and benefits were discounted at 3% annually. Compared with no prophylactic HPV vaccine, the incremental cost-effectiveness ratio was 160,649.50 baht per quality-adjusted life-year. The mortality rate was reduced by 54.8%. The incidence of cervical cancer, cervical intraepithelial neoplasia grade 1, cervical intraepithelial neoplasia grade 2/3, and genital warts was reduced by up to 55.1%. Compared with commonly accepted standard thresholds recommended by the World Health Organization Commission on Macroeconomics and Health, the nationwide coverage of HPV vaccination in girls is likely to be cost-effective in Thailand.

Only eight women out of one hundred diagnosed with ovarian epithelial cancers, which progressed to the clinical stage IV, survive 10 years. First line therapies: surgery, chemotherapy, and radiation therapy inflict very serious iatrogenic consequences. Passive immunotherapy of ovarian cancers offers only low efficacy. Prophylactic and therapeutic vaccines for ovarian cancers are not available. Interestingly, prophylactic vaccines for Hepatitis B Viruses (HBV) are very effective. The specific aim of this work was to design, synthesize, and administer biomolecules, which would engage prophylactic, vaccination-induced immunity for HBV towards killing of ovarian cancer cells with high specificity and efficacy. Tissue biopsies, ascites, and blood were acquired from the patients, whose identities were entirely concealed in accordance with the Declaration of Helsinki, pursuant to the Institutional Review Board approval, and with the Patients' informed consent. By biomolecular engineering, we have created a novel family of biomolecules: antibody × vaccine engineered constructs (AVEC: anti-HER-2 × HBsAg). We have collected the blood from the volunteers, and measured the titers of anti-HBV antibodies resulting from the FDA approved and CDC scheduled HBV vaccinations. We have acquired tumor biopsies, ascites, and blood from patients suffering from the advanced ovarian cancers. We have established cultures of HER-2 over-expressing epithelial ovarian cancers: OV-90, TOC-112D, SKOV-3, as well as human ovary surface epithelial (HOSE) and human artery endothelial (HAE) cells. Treatment of the HER-2+ ovarian cancer cells with AVEC: anti-HER-2 × HBsAg, accompanied by administration of blood drawn from patients with high titers of the anti-HBV antibodies, resulted in much higher therapeutic efficacy as compared to treatment with the naked anti-HER-2 antibodies alone and/or with the relevant isotype antibodies. This treatment had practically no effect upon the HOSE and HAE

During a 4-year period, 1978-1981, 312 patients were operated on for unilateral rhegmatogenous detachment of the retina. Of the fellow eyes, 11% showed moderate (VA 0.15-0.4) and 5% severe (VA less than or equal to 0.1) visual impairment. Of the fellow eyes 49% were myopic (- 1.0 D. or more), and aphakia was present in 14%. Details of the peripheral fundus were adequately recordable for 260 fellow eyes. Degenerations considered to predispose to retinal detachment were found in 98 eyes (38%): lattice degeneration in 54 (21%), granular tuft in 17 (7%), retinal tear(s) in 12 (5%), and retinoschisis in 15 (6%). Prophylactic treatment of predisposing degenerations was performed in 91 of the 98 eyes using cryo- or photocoagulation (argon laser). No intra- or permanent post-operative complications were noticed. One of the treated fellow eyes (1.1%) detached 10 months after prophylactic treatment due to new tears. In the untreated group, 6 of the 221 eyes detached (2.7%). The difference was not statistically significant, but the groups were not comparable because 93% of the eyes showing predisposing degenerations were treated. None of the eyes treated for retinal breaks or lattice degeneration has detached. In these cases prophylactic treatment of the fellow eye is recommended. In most eyes cryocoagulation seems to be preferable to photocoagulation.

A best evidence topic in thoracic surgery was written according to a structured protocol. The question addressed was 'In patients with tumours involving the phrenic nerve, does prophylactic diaphragm plication improve lung function following tumour resection?' Using the reported search, 258 papers were found of which 6 represented the best evidence to answer the clinical question. The authors, journal, date and country of publication, patient group studied, study type, relevant outcomes and results of these papers are tabulated. Three case reports and one case series represent 37 patients in the literature along with two relevant animal studies. Patients treated with prophylactic plication at the time of injury or sacrifice of the phrenic nerve had reduced radiological evidence of diaphragm paralysis, lower reported shortness of breath and reduced requirement for ventilatory support. In patients with prophylactic diaphragm plication and a concurrent pulmonary resection, the predicted postoperative lung function correlated closely with the postoperative measured FEV1, FVC and gas transfer. The postoperative measured FEV1 was reported as 86-98%, the FVC 82-89% and gas transfer 97% of the predicted values. Two animal models investigate the mechanics of respiration, spirometry and gas exchange following diaphragmatic plication. A randomized control study in four dogs measured a 50% reduction in tidal volume and respiratory rate, a 40% decrease in arterial PO2 and a 43% increase in arterial CO2 when the phrenic nerve was crushed in animals with a pneumonectomy but without prophylactic diaphragm plication. A further randomized control animal study with 28 dogs found that plicating the diaphragm after unilateral phrenic nerve transection resulted in a significant increase in tidal volume and lung compliance and a significant decrease in respiratory frequency and the work of breathing. Prophylactic diaphragm plication may preserve lung function, reduce the risk of

Purpose: To develop an evidence-based clinical practice guideline that would address the following questions: (a) What is the role of prophylactic cranial irradiation (PCI) in patients with limited or extensive stage small-cell lung cancer (SCLC) who have achieved complete remission in response to induction therapy (chemotherapy or chemoradiotherapy)? (b) What dose and fractionation schedules of PCI are optimal? (c) Does the use of PCI in patients with SCLC in complete remission affect quality of life? Survival, disease-free survival, quality of life, and adverse effects were the outcomes of interest. Methods and Materials: A systematic review of the published literature was undertaken to provide the data for an evidence-based practice guideline. Results: Six randomized controlled trials and one fully published individual patient data meta-analysis were included in the systematic review of the evidence. For patients who have achieved complete response after induction therapy, there is evidence of a disease-free survival benefit (4 of 6 trials) and an overall survival benefit (meta-analysis). There is insufficient evidence to make a definitive recommendation with respect to dose. There is some indication that 30-36 Gy in 2-3 Gy per fraction, or a biologically equivalent dose, may produce a better outcome than a lower dose or less aggressive fractionation regimen. The schedule commonly used in Canada is 25 Gy in 10 fractions over 2 weeks. Data from further research, including a trial currently ongoing that compares 25 Gy in 10 fractions with 36 Gy in 18 fractions, will be required to determine optimal dose of PCI. There is insufficient evidence to make recommendations concerning the optimal timing of PCI in relation to the administration of chemotherapy. Lung DSG members generally felt that it should be given as soon as possible after completion of chemotherapy. There is evidence from trials with data for up to 2 years of follow-up that prophylactic cranial

Purpose/Objective: To determine the effect of post-operative radiation on the incidence of heterotopic ossification following traumatic acetabular fracture. Materials and Methods: A retrospective analysis was performed of the medical records and radiographs of all patients who received prophylactic radiotherapy to prevent heterotopic ossification. These results were compared to a similar group of patients receiving no prophylactic radiotherapy following traumatic acetabular fracture. Between 1987 and 1994, sixty-six patients received prophylactic radiotherapy to prevent heterotopic ossification. Results: Thirty-six patients (55%) received radiotherapy following operative repair of a traumatic acetabular fracture (median follow-up: 210 days). Three dose schedules were utilized: (28(36)) (77.8%) received 700 cGy/1 fx, (2(36)) (5.5%) 800 cGy/1 fx, and (6(36)) (16.7%) 1000 cGy/5 fxs. These patients were retrospectively compared with thirty-four patients who received similar operative management of traumatic acetabular fractures without post-operative radiotherapy (median follow-up: 378 days). Of the patients with heterotopic ossification, 96% developed it within 180 days. Complications and delayed wound healing rates were not significantly different in patients treated with or without post-operative radiotherapy, 6.4% and 6.3% respectively (p=0.49). The incidence of heterotopic ossification at last follow-up in patients treated with and without post-operative radiotherapy was (5(36)) (13.9%) and (19(34)) (55.9%), respectively (p=0.000332). For all patients, type of surgical approach was associated with development of heterotopic ossification: posterior, (7(38)) (18.4%), ilio-inguinal (1(3)) (33.3%), tri-radiate (13(19)) (68.4%), p=.000511. In patients receiving post-operative radiotherapy, variables associated with heterotopic ossification included dose (p=.00962), injury-to-radiation interval (p=.0038), and surgery-to-radiation interval (p=.0238). Fifty percent ((3

Acute renal failure induced by contrast media is an important problem in renal insufficiency patients. Prophylactic hemodialysis is usually undertaken after the administration of radiocontrast media. However, we decided to cease giving prophylactic hemodialysis from February, 2002 in line with the guidelines regarding dialysis and contrast media administration provided by the European Society of Urogenital Radiology. We reported our policy at the doctor's meeting of hemodialysis therapy and at the meeting of clinical engineering technologists which were held in Okinawa. After the presentation, a questionnaire survey in 28 hospitals was undertaken by telephone. In all the hospitals, prophylactic hemodialysis after the administration of radiocontrast media was still being continued, with the exception of one hospital. We need to enlighten medical staff that the strategy of performing hemodialysis immediately after the administration of contrast media in patients with reduced renal function does not diminish the rate of radiocontrast media-induced nephropathy.

Prophylactic iodine treatment in radiation protection

International Nuclear Information System (INIS)

Oberhausen, E.

1980-01-01

Prophylactic iodine treatment is to prevent accumulation of radioactive iodine in the thyroid. This is done by administering a large amount of stable iodine before uptake of radioactive iodine so that further accummulation of iodine in the thyroid will be impossible. This blocking effect should be as complete as possible. This is achieved by administering an initial dose of 200 mg potassium iodide. As the release of radioactive iodine may last several hours or even days; for this reason, maintenance doses of 100 mg potassium iodide should be administered in 8-hour intervals. The risk of prophylactiv iodine treatment is rather low; however, provocation of latent hyperthyreoses must be expected in, at the most, 0.2% of the exposed population. (orig./MG) [de

Purpose: The main purpose of this study was to determine influential factors related to minor leukoencephalopathy (LEP) caused by moderate-dose methotrexate (MTX) and prophylactic cranial radiotherapy (CRT) in childhood hematopoietic malignancies. We also compared the incidence of LEP following this treatment to that reported in the literature following treatment with high-dose MTX alone. Methods and Materials: Thirty-eight pediatric patients of hematopoietic malignancies (37 acute lymphoblastic leukemias, 1 non-Hodgkin lymphoma) who were given CRT (18-24 Gy) as well as prophylactic intrathecal and per os MTX were studied for leukoencephalopathy by magnetic resonance (MR) imaging. All the patients were free from grave neuropsychiatric disturbances. The data were examined to elucidate the influential ones of five factors (patients' age, doses of intrathecal and per os MTX, dose of CRT, interval between treatment, and MR study) to develop LEP using multiple regression analysis. To compare the effect of moderate-dose MTX and prophylactic CRT on LEP to that of high-dose MTX alone, we conducted literature review. Results: Seven out of 38 patients (18%) developed LEP. From multiple regression analysis and partial correlation coefficients, the age and CRT dose seemed influential in the subsequent development of LEP. The incidence of LEP following treatment with moderate-dose MTX and prophylactic CRT appears to be less than that reported in the literature following treatment with intravenous high-dose MTX. However, even moderate-dose MTX in combination with CRT can result in a significant incidence of MR-detectable LEP, particularly in children 6 years of age or younger receiving 24 Gy. Conclusion: Leukoencephalopathy was caused by moderate-dose MTX and prophylactic CRT in pediatric patients, probably less frequently than by high-dose MTX treatment alone. The influential factors were patient's age and CRT dose

To evaluate the efficacy of ampicillin versus cefazolin as prophylactic antibiotics prior to cesarean delivery in Rwanda. In a prospective, randomized, open-label, single-site study conducted between March and May 2012, the effects of prophylactic ampicillin versus cefazolin were compared among women undergoing cesarean delivery at the Centre Hospitalier Universitaire de Kigali, Rwanda. Postoperatively, participants were evaluated daily for infectious morbidity while in the hospital. Follow-up was done by phone and by appointment at the hospital within 2 weeks of delivery. During the study period, there were 578 total deliveries and 234 cesarean deliveries (40.4%). Overall, 132 women were enrolled in the study and randomized to receive either ampicillin (n=66) or cefazolin (n=66). No women were lost to follow-up. The overall infection rate was 15.9% (21/132). The infection rate in the ampicillin group and the cefazolin group was 25.8% (17/66) and 6.1% (4/66), respectively. Implementing a universal protocol in Rwanda of prophylactic cefazolin prior to cesarean delivery might reduce postoperative febrile morbidity, use of postoperative antibiotics, and number of postoperative days in hospital.

Thrombocytopenia is a hallmark of dengue infection, and bleeding is a dreaded complication of dengue fever. Prophylactic platelet transfusion has been used to prevent bleeding in the management of dengue fever, although the evidence for its benefit is lacking. In adult dengue patients with platelet count Tan Tock Seng Hospital from January 2005 to December 2008. Baseline characteristics and clinical outcomes were compared between the non-transfused vs. transfused groups. Outcomes studied were clinical bleeding, platelet increment, hospital length of stay, intensive care unit admission and death. Of the 788 patients included, 486 received prophylactic platelet transfusion. There was no significant difference in the presence of clinical bleeding in the two groups (18.2% in non-transfused group vs. 23.5% in transfused group; P = 0.08). Patients in the transfused group took a median of 1 day longer than the non-transfused group to increase their platelet count to 50,000/mm3 or more (3 days vs. 2 days, P hospital stay in the non-transfused group was 5 days vs. 6 days in the transfused group (P50,000/mm3 and increasing length of hospitalization.

Objective The objective of this study was to evaluate the safety and efficacy of tamsulosin hydrochloride 0.2 mg (TAM) and its combination with solifenacin succinate 5 mg (SOL) after transurethral resection of the prostate (TURP). Patients and methods The patients were randomized into three groups: TURP (group 1), TURP plus TAM (group 2), and TURP plus TAM + SOL (group 3). Patients in group 2 and group 3 received medication for 4 weeks. The primary efficacy end points were the mean change in total International Prostate Symptom Score (IPSS) and IPSS subscores. The secondary end points included quality-of-life score, Overactive Bladder Symptom Score, and short-form voiding and storage score of International Continence Society. Results In total, 37 men (31.8%) in group 1, 37 men (31.8%) in group 2, and 42 men (36.2%) in group 3 completed the study. In total IPSS, no significant improvement was seen from baseline to the end of treatment in groups 2 and 3 compared with group 1. However, in group 2, the decrement in the IPSS storage score was smaller than group 1 (P=0.02), and in group 3, the decrement in the IPSS voiding score was smaller than group 1 (P=0.05). In groups 2 and 3 compared with group 1, improvements in the quality of life score, total score of Overactive Bladder Symptom Score, and short-form voiding score and storage score of International Continence Society were not statistically significant. Conclusion Treatment with TAM and combination of TAM and SOL did not have significant additional benefits for lower urinary tract symptoms during the early recovery period after TURP. PMID:27698559

Full Text Available INTRODUCTION: Continuous ambulatory peritoneal dialysis (CAPD peritonitis may develop after endoscopic procedures, and the benefit of prophylactic antibiotics is unclear. In the present study, we investigated whether prophylactic antibiotics reduce the incidence of peritonitis in these patients. PATIENTS AND METHODS: We retrospectively reviewed all endoscopic procedures, including esophagogastroduodenoscopy (EGD, colonoscopy, sigmoidoscopy, cystoscopy, hysteroscopy, and hysteroscopy-assisted intrauterine device (IUD implantation/removal, performed in CAPD patients at Chang Gung Memorial Hospital, Taiwan, between February 2001 and February 2012. RESULTS: Four hundred and thirty-three patients were enrolled, and 125 endoscopies were performed in 45 patients. Eight (6.4% peritonitis episodes developed after the examination. Antibiotics were used in 26 procedures, and none of the patients had peritonitis (0% vs. 8.1% without antibiotic use; p=0.20. The peritonitis rate was significantly higher in the non-EGD group than in the EGD group (15.9% [7/44] vs. 1.2% [1/81]; p<0.005. Antibiotic use prior to non-EGD examinations significantly reduced the endoscopy-associated peritonitis rate compared to that without antibiotic use (0% [0/16] vs. 25% [7/28]; p<0.05. Peritonitis only occurred if invasive procedures were performed, such as biopsy, polypectomy, or IUD implantation, (noninvasive procedures, 0% [0/20] vs. invasive procedures, 30.4% [7/23]; p<0.05. No peritonitis was noted if antibiotics were used prior to examination with invasive procedures (0% [0/10] vs. 53.8% [7/13] without antibiotic use; p<0.05. Although not statistically significant, antibiotics may play a role in preventing gynecologic procedure-related peritonitis (antibiotics, 0% [0/4] vs. no antibiotics, 55.6% [5/9]; p=0.10. CONCLUSION: Antibiotic prophylaxis significantly reduced endoscopy-associated PD peritonitis in the non-EGD group. Endoscopically assisted invasive procedures, such

Fenbendazole (FBZ) is a common, highly efficacious broad-spectrum anthelmintic drug used to treat and limit rodent pinworm infections. However, the effect of its prophylactic use on the immune response of rodents is largely undefined. The non-obese diabetic (NOD) mouse is a model commonly used to study type 1 diabetes (T1D). Parasitic infections will inhibit diabetes development in NOD mice; thus, in the presence of contamination, prophylactic treatment with anthelmintics must be considered to maintain experimental research. Herein, we investigated the prophylactic use of FBZ in NOD mice to determine its effect on the incidence and onset of diabetes, lymphocyte sub-populations and T cell proliferative responses. NOD mice were separated into control and treatment groups. The treatment group received a diet containing FBZ. Animals were monitored for the incidence and onset of T1D. At matched time points, diabetic and non-diabetic mice were killed and splenic lymphocytes analyzed for various cell sub-populations and mitogen-induced proliferative responses using flow cytometry. Treated and control mice were monitored >23 weeks with no detectable effects on the incidence or onset of diabetes. Moreover, no significant differences were detected in lymphocyte sub-populations and mitogen-induced CD4(+) and CD8(+) proliferative responses between control and treatment groups. These results suggest that prophylactic FBZ treatment does not significantly alter the incidence or onset of diabetes in NOD mice. The prophylactic use of FBZ, therefore, presents a viable approach for the prevention of pinworm infection in precious experimental animals with substantial scientific and economic benefits.

Prophylactic antibiotics for penetrating abdominal trauma.

Brand, Martin; Grieve, Andrew

2013-11-18

Penetrating abdominal trauma occurs when the peritoneal cavity is breached. Routine laparotomy for penetrating abdominal injuries began in the 1800s, with antibiotics first being used in World War II to combat septic complications associated with these injuries. This practice was marked with a reduction in sepsis-related mortality and morbidity. Whether prophylactic antibiotics are required in the prevention of infective complications following penetrating abdominal trauma is controversial, however, as no randomised placebo controlled trials have been published to date. There has also been debate about the timing of antibiotic prophylaxis. In 1972 Fullen noted a 7% to 11% post-surgical infection rate with pre-operative antibiotics, a 33% to 57% infection rate with intra-operative antibiotic administration and 30% to 70% infection rate with only post-operative antibiotic administration. Current guidelines state there is sufficient class I evidence to support the use of a single pre-operative broad spectrum antibiotic dose, with aerobic and anaerobic cover, and continuation (up to 24 hours) only in the event of a hollow viscus perforation found at exploratory laparotomy. To assess the benefits and harms of prophylactic antibiotics administered for penetrating abdominal injuries for the reduction of the incidence of septic complications, such as septicaemia, intra-abdominal abscesses and wound infections. Searches were not restricted by date, language or publication status. We searched the following electronic databases: the Cochrane Injuries Group Specialised Register, CENTRAL (The Cochrane Library 2013, issue 12 of 12), MEDLINE (OvidSP), Embase (OvidSP), ISI Web of Science: Science Citation Index Expanded (SCI-EXPANDED), ISI Web of Science: Conference Proceedings Citation Index- Science (CPCI-S) and PubMed.

To find out the occurrence of postoperative nausea and vomiting (PONY) in oral and maxillofacial surgery done under general anaesthesia and to evaluate the purpose of using prophylactic antiemetic drugs. Design: Observational study. Place and Duration of the Study: Oral and Maxillofacial Department, KEMU / Mayo Hospital Lahore, from September 20 II to June 2012. Method: The number of patients who were operated in oral and maxillofacial surgery ward irrespective of age and gender for this study were 240. Risk factors related with PONY including gender, anesthetic drug used, surgical procedure, approach' used, total time of surgery and postoperative use of opioids were investigated. A wait and watch scheme was followed in patients with complaint of PONY. Antiemetics to be given in those cases where more than 2 episodes of vomiting took place. Results: It was found out that only II patients experienced from nausea and vomiting in post operative period. A notable relation was seen between PONY and female population, total time of surgery, anesthetic drug, surgery of tumor and temporomandibular joint. The surgical approach and opioids in postoperative period for PONY were found to be insignificant. Conclusion: PONY is not a significant finding in oral and maxillofacial surgery. We find out that there is no logic for the use of prophylactic antiemetic drugs in maxillofacial surgery. (author)

[Prophylactic treatment of retinal detachment].

The indications for and results of prophylactic treatment of retinal detachment during a period of five years are reported and compared with the results in the literature. Half of the cases (3 out of 6 eyes) which developed a retinal detachment had been horse-shoe tears combined with a vitreous hemorrhage. For this reason a small buckle operation is recommended in these cases, to prevent further traction. Lattice degeneration should rather be observed than treated, except in special cases: This includes eyes where the fellow eye had a detachment from a lattice degeneration, cases in which one eye is blind from an uncured detachment or has no useful visual acuity, and eyes whose fellow eye has giant tears. In aphakic eyes treatment of lattice degeneration is recommended, because the incidence of detachment from these areas is high, especially in young aphakic cases. In one aphakic eye which had been photocoagulated several times the formation of a preretinal membrane was observed.

Retroperitoneal Bleeding: An Experience During Prophylactic Anticoagulation in a Patient With Nephrotic Syndrome

Directory of Open Access Journals (Sweden)

Mari Okada

2017-07-01

Full Text Available The association between nephrotic syndrome (NS and a hypercoagulable state has been demonstrated. Controlling the blood clotting activity may therefore be attractive for patients with nephrosis in terms of thromboembolism prophylaxis. We herein report a 75-year-old woman with minimal change disease who developed pains in the right back, groin, and thigh because of retroperitoneal bleeding during prophylactic anticoagulation with unfractionated heparin. Although this procedure has not been accepted as the standard of care for patients with nephrosis, pharmacologic prophylaxis may already be practiced empirically, as in the present patient. We believe that our experience highlights the pitfalls of such a management in patients with nephrosis, implying the need for a diagnostic strategy for identifying those patients with NS who can benefit from prophylactic anticoagulation. Several concerns that emerged in this case are also discussed.

For proximal gastric cancer invading the greater curvature, concomitant splenectomy is frequently performed to secure the clearance of lymph node metastases. However, prognostic impact of prophylactic splenectomy remains unclear. The aim of this study was to clarify the oncological significance of prophylactic splenectomy for advanced proximal gastric cancer invading the greater curvature. Retrospective review of 108 patients who underwent total or subtotal gastrectomy for advanced proximal gastric cancer involving the greater curvature was performed. Short-term and long-term outcomes were compared between the patients who underwent splenectomy (n = 63) and those who did not (n = 45). Patients who underwent splenectomy showed higher amount of blood loss (538 vs. 450 mL, p = 0.016) and morbidity rate (30.2 vs. 13.3, p = 0.041) compared with those who did not undergo splenectomy. In particular, pancreas-related complications were frequently observed among patients who received splenectomy (17.4 vs. 0%, p = 0.003). However, no significant improvement of long-term outcomes were confirmed in the cases with splenectomy (5-year recurrence-free rate, 60.2 vs. 67.3%; p = 0.609 and 5-year overall survival rates, 63.7 vs. 73.6%; p = 0.769). On the other hand, splenectomy was correlated with marginally better survival in patients with Borrmann type 1 or 2 gastric cancer (p = 0.072). For advanced proximal gastric cancer involving the greater curvature, prophylactic splenectomy may have no significant prognostic impact despite the increased morbidity rate after surgery. Such surgical procedure should be avoided as long as lymph node involvement is not evident.

Prophylactic Antiviral Treatment in Recurrent Herpes Zoster: A Case Report

Full Text Available Herpes zoster (HZ occurs in older ages with activation of varicella-zoster virus (VZV which persists in a dormant phase within the dorsal root ganglia. The incidence of HZ in immunosuppressed patients is 20-100 times higher and the clinical progress is more severe than in immunocompetent individuals. A 48-year-old man who had been diagnosed with acute myelocytic leukemia type M3 and had been treated with immunosuppressive agents was admitted to our clinic. The patient was clinically diagnosed as having HZ. He was treated with acyclovir 800 mg five times daily for 7 days. In the consecutive three months, he attended our clinic again with similar complaints. The left cervical (C5, C6 dermatomes were involved at the fourth attack of HZ. Multinucleated giant cells were determined on the Tzanck smear. VZV DNA was detected by polymerase chain reaction (PCR. Treatment with valacyclovir 1 g three times daily for 14 days was prescribed and then, prophylactic treatment with valacyclovir 500 mg two times a day was administered. Although immunosuppressive treatment was continued, no new attacks of herpes zoster occurred. We think that prophylactic antiviral therapy should be initiated in immunosuppressive individuals who have recurrent herpes zoster attacks.

Purpose This study examined the efficacy of the postoperative prophylactic antibiotics used in orthognathic surgery. The prevalence of surgical site infections (SSIs) was determined according to the use of postoperative prophylactic antibiotics. Patients and Methods Fifty-six patients were divided into 2 groups. Each patient intravenously received 1.0 g of a third-generation cephalosporin (Cefpiramide) 30 minutes before surgery. Among them, 28 patients in the control group received 1.0 g Cefpiramide twice daily until the third day after surgery. The postoperative wounds were examined regularly for the presence of infectious signs. Results There was no significant difference in the incidence of postoperative wound infections between patients who had received postoperative prophylactic antibiotic administration and those who had not (p = 0.639). Conclusion Prolonged prophylactic antibiotic use after orthognathic surgery may not be necessary, provided that there are no other significant factors for wound infections. PMID:19259349

Full Text Available Surgical site infections are one of the most important post-surgery complications. Antimicrobial prophylaxis has been used routinely in surgeries to reduce infection incidence. However, inappropriate selection of antimicrobial agents or dosing can develop antimicrobial resistance, serious adverse reactions and prolong hospitalization. Current study aimed to examine prophylactic antibiotic prescription in surgeries in a teaching hospital in Sari, Mazandaran and evaluate level of adherence to the international guidelines. Between January 2015 to May 2015, 104 patients in general surgery ward were selected and enrolled in the study. The prophylactic antibiotics, dosage, timing and duration of administration were collected by reviewing patients’ records and compared to the existing guidelines. Prophylactic antibiotic was given to 85.5% of patients. Prescribed antibiotics were cefazolin (46.1%, metronidazole (24%, ceftriaxone (12.5%, ciprofloxacin (1.9% and vancomycin (0.96%. Most of the patients (62.9% received an inappropriate and delayed timing. Proper antibiotic dosage was seen in 45.2% of patients. All patients received post-operative prophylactic antibiotic. Main antibiotics include cefazolin (41.3%, metronidazole (33.7%, ceftriaxone (31.7% and clindamycin (20.2%. Only 10 (21.9% patients received cefazolin or vancomycin for a total duration of 48 hours or less. Surgical wound infection occurred in 17 (16.3% patients during hospital stay. Adherence to antimicrobial prophylaxis guidelines was completely achieved in 14.4% of cases. Results of this study signified that adherence to existing guidelines was poor and the most common mistakes were over usage, inappropriate dosage and choosing of antibiotics.

We included studies assessing both a group of patients with and without embolization.ResultsOur search revealed 1401 articles of which title and abstract were screened. Finally, eight studies were included investigating 1237 patients. Of these patients, 456 received embolization of one or more arteries. No difference was seen in the incidence of gastrointestinal complications in patients with prophylactic embolization of the gastroduodenal artery (GDA), right gastric artery (RGA), cystic artery (CA) or hepatic falciform artery (HFA) compared to patients without embolization. Few complications were reported when microspheres were injected distal to the origin of these arteries or when reversed flow of the GDA was present. A high risk of confounding by indication was present because of the non-randomized nature of the included studies.ConclusionIt is advisable to restrict embolization to those hepaticoenteric arteries that originate distally or close to the injection site of microspheres. There is no conclusive evidence that embolization of hepaticoenteric arteries influences the risk of complications.

Pressure ulcer prevention and treatment: use of prophylactic dressings

Full Text Available Kathleen Reid,1 Elizabeth A Ayello,2 Afsaneh Alavi,3 1Department of Nursing Practice and Education, Bridgepoint Active Healthcare, Toronto, Canada; 2School of Nursing, Excelsior College, Albany, NY, USA; 3Department of Medicine, University of Toronto, Toronto, Canada Abstract: The management of pressure ulcers is challenging for health care providers across disciplines. Pressure ulcers have significant impact on emotional and physical wellbeing, quality of life, and health care costs. The use of wound dressings could be an important and cost-effective strategy in preventing pressure ulcers. The main types of dressings that are examined for this purpose in the literature are foam, hydrocolloid, and films. Some small studies have shown a preventative role for sacral dressings with low-shear backings, though they raise concerns about over-hydration of the skin. Further research demonstrates the application of barrier films over bony prominences to have a prophylactic effect; however, adhesive dressings can also contribute to shearing forces on the skin. There is a vast body of research that examines the use of dressings to prevent pressure ulcers; however, there is limited high-level evidence, such as randomized control trials. A 2013 Cochrane review indicated that there is a paucity of high-level evidence to support the prophylactic use of dressings to prevent pressure ulcers; this paper will examine the emerging literature and consider its relevance to pressure ulcer prevention protocols.

Lung cancer is the most common malignant disease in the United States. Only the few tumors detected very early are curable, but there has been some progress in the management of more advanced non-small cell lung cancer, particularly in regionally inoperable disease. Prevention of central nervous system relapse is an important issue in this group of patients because brain metastases ultimately develop in 20% to 25% of them. Seventy-three patients with regionally advanced non-small cell lung cancer were entered into a Phase II trial of neutron chest radiotherapy sandwiched between four cycles of chemotherapy including cisplatin, vinblastine, and mitomycin C. Prophylactic cranial irradiation was administered concurrently with chest radiotherapy (3000 cGy in 10 fractions in 15 patients; 3600 cGy in 18 fractions in the remaining 50 patients). Patients underwent computed tomographic scan of the brain before treatment and every 3 months after treatment. The initial overall response rate was 79%, but 65 of the 73 patients have subsequently died of recurrent disease. Median follow-up is 9 months for all 73 patients and 26 months for eight long-term survivors. No patient who completed the prophylactic cranial irradiation program had clinical or radiologic brain metastases. Toxic reactions to prophylactic cranial irradiation included reversible alopecia in all patients, progressive dementia in one patient, and possible optic neuritis in one patient. Both of these patients received 300 cGy per fraction of irradiation. The use of prophylactic cranial irradiation has been controversial, but its safety and efficacy in this trial supports its application in a group of patients at high risk for central nervous system relapse. Further evaluation of prophylactic cranial irradiation in clinical trials for regionally advanced non-small cell lung cancer is warranted.

Full Text Available Purpose: Alpha1 (α1-adrenoceptor antagonists are widely used to treat lower urinary tract symptoms. These drugs not only act on peripheral tissues, but also cross the blood-brain barrier and affect the central nervous system. Therefore, α1-adrenoceptor antagonists may enhance brain functions. In the present study, we investigated the effects of tamsulosin, an α1-adrenoceptor antagonist, on short-term memory, as well as spatial learning and memory, in rats. Methods: The step-down avoidance test was used to evaluate short-term memory, and an eight-arm radial maze test was used to evaluate spatial learning and memory. TUNEL (terminal deoxynucleotidyltransferase-mediated dUTP nick end labeling staining was performed in order to evaluate the effect of tamsulosin on apoptosis in the hippocampal dentate gyrus. Patch clamp recordings were used to evaluate the effect of tamsulosin on ionotropic glutamate receptors, such as N-methyl-D-aspartate (NMDA, amino-3-hydroxy-5-methyl-4-isoxazolepropionate (AMPA, and kainate receptors, in hippocampal CA1 neurons. Results: Tamsulosin treatment improved short-term memory, as well as spatial learning and memory, without altering apoptosis. The amplitudes of NMDA-induced ion currents were dose-dependently increased by tamsulosin. However, the amplitudes of AMPA- and kainate-induced ion currents were not affected by tamsulosin. Conclusions: Tamsulosin enhanced memory function by activating NMDA receptor-mediated ion currents in the hippocampus without initiating apoptosis. The present study suggests the possibility of using tamsulosin to enhance memory under normal conditions, in addition to its use in treating overactive bladder.

There exists few pediatric data on the safety and efficacy of prophylactic antibiotics during chemotherapy-induced agranulocytosis. We prospectively studied the incidence of infection-related fever in 38 children, aged 2-16 years, with acute myeloid leukemia (AML) over 121 chemotherapy treatment cycles. A prophylactic group (n = 18) was given either vancomycin/cefepime (400 mg/m(2), q12 h/50 mg/kg, q12 h) or piperacillin/tazobactam (110 mg/kg, q12 h). Control patients (n = 20) received no preventive antibiotics. The prophylactic group (59 treatment cycles) experienced fever less frequently than the control group (0.4 vs. 0.9 events; p chemotherapy-induced agranulocytosis can effectively reduce the incidence of infectious fever and can shorten the average length of hospital stay, improving treatment success and quality of life. © 2014 S.

Background: In recent years, radical breast cancer surgery has been largely replaced by breast conservation treatment, due to early diagnosis and more effective adjuvant treatment. While breast conservation is mostly preferred, the trend of bilateral mastectomy has risen in the United States. The aim of this study is to determine factors influencing patients’ choice for having contralateral prophylactic mastectomy (CPM). Methods: This is a retrospective study of 373 patients diagnosed with primary invasive breast cancer who were treated by bilateral or unilateral mastectomy (BM or UM) at the Revlon/UCLA Breast Center between Jan. 2002 and Dec. 2010. In the BM group, only those with unilateral breast cancer who chose CPM were included in the analysis. Results: When compared with the UM group, the following factors were found to be associated with BM: younger age, pre-menopausal, a family history of breast/ovarian cancer, BRCA mutation, more breast biopsies, history of breast augmentation, having MRI study within 6 months before the surgery, more likely to have reconstruction and sentinel lymph node biopsy (SLNB) and fewer had neoadjuvant/adjuvant chemotherapy/radiation. When patients with bilateral breast cancer were excluded, multivariate logistic regression analysis indicated younger patients with negative nodes, SLNB as the only nodal surgery and positive family history were significant factors predicting CPM and immediate reconstruction using tissue expanders or implants. Conclusion: Younger age, lower TN stage, requiring only SLNB and high risk family history predict contralateral prophylactic mastectomy. Tissue expander/implant-based reconstructions were more frequently chosen by patients with BM. PMID:26097557

The administration of high-dose interleukin-2 (IL-2) causes tumor regression in 17-25% of patients with metastatic melanoma or renal cell carcinoma. Renal dysfunction is a common dose-limiting toxicity of IL-2 administration, limiting 26% of treatment cycles. We have conducted a prospective randomized trial to evaluate whether the prophylactic administration of low-dose dopamine (2 mg/kg/min) can minimize renal toxicity and thus affect the amount of IL-2 administered. Forty-two patients were randomly assigned to receive systemic high-dose IL-2 with standard supportive measures (group A = 21 patients) or with the addition of prophylactic dopamine (group B = 21 patients) at 2 mg/kg/min. For patients in group B, dopamine was instituted 1 h before the initiation of IL-2 administration and was discontinued 6-12 h after the maximum number of doses of IL-2 were given. There was no difference in the amount of IL-2 administered for each course of therapy for groups A and B. Despite differences in urine flow (milliliters per kilogram per day), fluid balance (liters per day), and overall weight gain, prophylactic low-dose dopamine did not significantly alter maximum plasma urea or creatinine levels in group B when compared with the control group (group A). The overall toxicity profile considering all grade 3 and 4 toxicities for patients in groups A and B was comparable. Thus, there is no evidence to support the routine use of prophylactic low-dose dopamine in patients receiving high-dose IL-2.

An alarming increase in emergence of antibiotic resistance among pathogens worldwide has become a serious threat to our ability to treat infectious diseases according to the World Health Organization. Extensive use of antibiotics by livestock producers promotes the spread of new resistant strains, some of zoonotic concern, which increases food-borne illness in humans and causes significant economic burden on healthcare systems. Furthermore, consumer preferences for meat/poultry/fish produced without the use of antibiotics shape today's market demand. So, it is viewed as inevitable by the One Health Initiative that humans need to reduce the use of antibiotics and turn to alternative, improved means to control disease: vaccination and prophylactics. Besides the intense research focused on novel therapeutic molecules, both these strategies rely heavily on the availability of cost-effective, efficient and scalable production platforms which will allow large-volume manufacturing for vaccines, antibodies and other biopharmaceuticals. Within this context, plant-based platforms for production of recombinant therapeutic proteins offer significant advantages over conventional expression systems, including lack of animal pathogens, low production costs, fast turnaround and response times and rapid, nearly-unlimited scalability. Also, because dried leaves and seeds can be stored at room temperature for lengthy periods without loss of recombinant proteins, plant expression systems have the potential to offer lucrative benefits from the development of edible vaccines and prophylactics, as these would not require "cold chain" storage and transportation, and could be administered in mass volumes with minimal processing. Several biotechnology companies currently have developed and adopted plant-based platforms for commercial production of recombinant protein therapeutics. In this manuscript, we outline the challenges in the process of livestock immunization as well as the current

Develop a risk prediction model for severe intraventricular hemorrhage (IVH) in very low birth weight infants (VLBWI). Prospectively collected data of infants with birth weight 500 to 1249 g born between 2001 and 2010 in centers from the Neocosur Network were used. Forward stepwise logistic regression model was employed. The model was tested in the 2011 cohort and then applied to the population of VLBWI that received prophylactic indomethacin to analyze its effect in the risk of severe IVH. Data from 6538 VLBWI were analyzed. The area under ROC curve for the model was 0.79 and 0.76 when tested in the 2011 cohort. The prophylactic indomethacin group had lower incidence of severe IVH, especially in the highest-risk groups. A model for early severe IVH prediction was developed and tested in our population. Prophylactic indomethacin was associated with a lower risk-adjusted incidence of severe IVH.

Silodosin is a new selective therapy with a high pharmacologic selectivity for the a (1A)-adrenoreceptor. Our aim was to test silodosin's superiority to placebo and noninferiority to tamsulosin and discuss the findings in the context of a comprehensive literature review of the new compound silodosin. We conducted a multicenter double-blind, placebo-and active-controlled parallel group study. A total of 1228 men > or = 50 yr of age with an International Prostate Symptom Score (IPSS) 4 and silodosin 8 mg (n = 381), tamsulosin 0.4 mg (n = 384), or placebo (n = 190) once daily for 12 wk. We calculated the change from baseline in IPSS total score (primary), storage and voiding subscores, quality of life (QoL) due to urinary symptoms, and Q(max). Responders were defined on the basis of IPSS and Q(max) by a decrease of > or = 25% and an increase of > or = 30% from baseline, respectively. The change from baseline in the IPSS total score with silodosin and tamsulosin was significantly superior to that with placebo (p silodosin and -2.0 (95% CI, -2.9, -1.1) with tamsulosin. Responder rates according to total IPSS were significantly higher (p silodosin (66.8%) and tamsulosin (65.4%) than with placebo (50.8%). Active treatments were also superior to placebo in the IPSS storage and voiding subscore analyses, as well as in QoL due to urinary symptoms. Of note, only silodosin significantly reduced nocturia versus placebo (the change from baseline was -0.9, -0.8, and -0.7 for silodosin, tamsulosin, and placebo, respectively; p = 0.013 for silodosin vs placebo). An increase in Q(max) was observed in all groups. The adjusted mean change from baseline to end point was 3.77 ml/s for silodosin, 3.53 ml/s for tamsulosin, and 2.93 ml/s for placebo, but the change for silodosin and tamsulosin was not statistically significant versus placebo because of a particularly high placebo response (silodosin vs placebo: p = 0.089; tamsulosin vs placebo: p = 0.221). At end point, the percentage of

Full Text Available Introduction: Wound infection is one of the most common complications of surgical procedures.At present, different procedures are used to reduce wound infection including prophylactic antibiotics.Since laparoscopy controls the most sources of wound infection such as mechanical factors, the role ofprophylactic antibiotic therapy may be in doubt. In this study, we evaluated the antibiotic effects inprevention of wound infection in laparoscopic cholecystectomy.Methods and Materials: In this double-blind clinical trial study, patients who were candidate forlaparoscopic cholecystectomy were divided randomly into two groups: antibiotic receivers (38patients and placebo (Normal Saline receivers (32 patients group. The patients were visited in 24hours, 4-7, 10-15 and 30 days after surgery for wound infection and then 2 groups compared.Results: The study showed that there were no significant differences between two groups withrespect to age, body mass index and smoking. In addition, no wound infection was observed in first 24hours, 4-7, 10-15 and 30 days after operation in both groups.Conclusion: The findings showed that prophylactic antibiotic therapy in laparoscopiccholecystectomy has no effect on the incidence of wound infection. Therefore, it is suggested thatprophylactic antibiotic therapy does not use in laparoscopic cholecystectomy because of producingantibiotic resistance, unnecessary complications and also reducing economical costs.

2012-01-01

Full Text Available Prophylactic breast bud radiotherapy is used to prevent gynaecomastia and mastalgia in patients with prostate cancer who are being treated with antiandrogen and oestrogen therapy. Here a case is presented of a patient who developed soft-tissue sarcoma of the breast subsequent to breast bud radiotherapy prior to bicalutamide hormone treatment. Bicalutamide is often prescribed for younger men in the adjuvant setting or as monotherapy for locally advanced disease. The data regarding the efficacy of prophylactic breast bud radiotherapy is reviewed, and it is proposed that alternative therapies should be considered such as tamoxifen.

Thirty-five patients who were to begin pelvic irradiation for malignant disease were randomized to receive ibuprofen 400 mg P.O. q.i.d. during their radiotherapy or standard therapy for radiation-induced gastrointestinal symptoms. Seventeen of 19 patients in the ibuprofen group completed the protocol. There was no significant difference in the daily stool frequency between the ibuprofen and control patients during the 5 to 6 week course of pelvic irradiation; the incidence and severity of diarrhea was the same. There was no significant difference in the incidence of nausea reported by the patients but the severity of nausea was less in the ibuprofen group; none of the 17 patients in the ibuprofen group reported vomiting at any time, whereas, 27% of the patients in the control group reported vomiting. The difference was statistically significant (p < 0.05). The data suggest that prophylactic ibuprofen administration may be beneficial in reducing the severity of nausea and preventing radiation-induced vomiting in patients who receive pelvic irradiation

Role of healthcare workers in early epidemic spread of Ebola: policy implications of prophylactic compared to reactive vaccination policy in outbreak prevention and control.

Ebola causes severe illness in humans and has epidemic potential. How to deploy vaccines most effectively is a central policy question since different strategies have implications for ideal vaccine profile. More than one vaccine may be needed. A vaccine optimised for prophylactic vaccination in high-risk areas but when the virus is not actively circulating should be safe, well tolerated, and provide long-lasting protection; a two- or three-dose strategy would be realistic. Conversely, a reactive vaccine deployed in an outbreak context for ring-vaccination strategies should have rapid onset of protection with one dose, but longevity of protection is less important. In initial cases, before an outbreak is recognised, healthcare workers (HCWs) are at particular risk of acquiring and transmitting infection, thus potentially augmenting early epidemics. We hypothesise that many early outbreak cases could be averted, or epidemics aborted, by prophylactic vaccination of HCWs. This paper explores the potential impact of prophylactic versus reactive vaccination strategies of HCWs in preventing early epidemic transmissions. To do this, we use the limited data available from Ebola epidemics (current and historic) to reconstruct transmission trees and illustrate the theoretical impact of these vaccination strategies. Our data suggest a substantial potential benefit of prophylactic versus reactive vaccination of HCWs in preventing early transmissions. We estimate that prophylactic vaccination with a coverage >99% and theoretical 100% efficacy could avert nearly two-thirds of cases studied; 75% coverage would still confer clear benefit (40% cases averted), but reactive vaccination would be of less value in the early epidemic. A prophylactic vaccination campaign for front-line HCWs is not a trivial undertaking; whether to prioritise long-lasting vaccines and provide prophylaxis to HCWs is a live policy question. Prophylactic vaccination is likely to have a greater impact on the

Trema orientalis (T. orientalis Linn) has been used in the management of malaria in the western part of Nigeria and despite its application in ethnomedicine, there is dearth of scientific evidence to justify the acclaimed prophylactic antimalarial usage of the plant. The aim of this study is to assess the in vitro antiplasmodial cell-free assay and chemopreventive efficacy of the methanol extract of the stem bark of T. orientalis and its fractions as a prophylactic regimen for malaria prevention. Also, the antimicrobial activities of the extract and the fractions were investigated. Vacuum liquid chromatography was used to obtain dichloromethane, ethylacetate and methanol fractions from the methanol extract of T. orientalis. The fractions were tested for their prophylactic and cell-free antimalarial activity using murine models and β-hematin formation assay respectively. Disc diffusion method was used to determine the antibacterial activity of the extract and its fractions against both Gram-positive and Gram-negative bacteria. In the prophylactic experiment, dichloromethane (DCMF), methanol fraction (MF) and extract (ME) (in this order) showed significant chemopreventive effects against P. berghei invasion of the red blood cells when compared with both Sulfadoxine-Pyrimethamine (SP) and untreated controls. Results of the in vitro study showed that the DCMF had the highest effect in preventing the formation of β-hematin when compared with other fractions. The DCMF also had the highest percentage inhibition of β-hematin formation when compared with chloroquine. The extract and fractions showed a concentration dependent antibacterial activity. Methanol extract had a pronounced inhibitory effect on Enterobacter cloaca ATCC 13047 and Enterococcus faecalis ATCC 29212. Serratia mercescens ATCC 9986 and Pseudomonas aeruginosa ATCC 19582 were the most susceptible bacteria. The results obtained showed that both extract and fractions of T. orientalis possessed

Negative pressure wound therapy (NPWT) is increasingly used prophylactically following surgery despite limited evidence of clinical or cost-effectiveness. To evaluate whether NPWT is cost-effective compared to standard care, for the prevention of surgical site infection (SSI) in obese women undergoing elective caesarean section, and inform development of a larger trial. An economic evaluation was conducted alongside a pilot randomised controlled trial at one Australian hospital, in which women were randomised to NPWT (n = 44) or standard care (n = 43). A public health care provider perspective and time horizon to four weeks post-discharge was adopted. Cost-effectiveness assessment was based on incremental cost per SSI prevented and per quality-adjusted life year (QALY) gained. Patients receiving NPWT each received health care costing AU$5887 (±1038) and reported 0.069 (±0.010) QALYs compared to AU$5754 (±1484) and 0.066 (±0.010) QALYs for patients receiving standard care. NPWT may be slightly more costly and more effective than standard care, with estimated incremental cost-effectiveness ratios (ICERs) of AU$1347 (95%CI dominant- $41,873) per SSI prevented and AU$42,340 (95%CI dominant- $884,019) per QALY gained. However, there was considerable uncertainty around these estimates. NPWT may be cost-effective in the prophylactic treatment of surgical wounds following elective caesarean section in obese women. Larger trials could clarify the cost-effectiveness of NPWT as a prophylactic treatment for SSI. Sensitive capture of QALYs and cost offsets will be important given the high level of uncertainty around the point estimate cost-effectiveness ratio which was close to conventional thresholds.

The aim of this study was to systematically review the literature on antibiotic prophylaxis in gynaecologic surgeries to prevent inflammatory complications after gynaecological operations. The study was carried out as a systematic review. Only randomised controlled trials of women undergoing gynaecological surgery were included. The Medline and the Cochrane library databases were searched from 1966 to 2016. The trials must have investigated an antibiotic intervention to prevent an inflammatory complication after gynaecological surgery. Trials were excluded if they were not randomised, uncontrolled or included obstetrical surgery. Prophylactic antibiotics prevent inflammatory complications after gynaecological surgery. Prophylactic antibiotics are more effective in surgery requiring access to the peritoneal cavity or the vagina. Cefotetan appears to be more capable in preventing the overall inflammatory complication rate than cefoxitin or cefazolin. No benefit has been shown for the combination of antibiotics as prophylaxis. No difference has been shown between the long-term and short-term use of antibiotics. There is no need for the primary use of an anaerobic antibacterial agent. Antibiotics help to prevent postoperative inflammatory complications after major gynecologic surgeries.

The authors performed a retrospective analysis on 296 phakic patients who had bilateral lattice degeneration and a retinal detachment in one eye. The analysis was done to determine the complications of full prophylactic treatment to lattice and breaks in the fellow eye and to explain the reasons that this treatment sometimes did not prevent new retinal breaks or detachments. The patients were followed for a mean +/- SD of 7.415 +/- 5.422 years after their first detachment. Twenty-four new tears occurred in the fellow eyes during this time, seven (29.2%) of which were away from areas of visible lattice. Prophylactic treatment did not appear to cause new tears or increase the risk of detachment if a new tear occurred. It also did not compromise the surgical repair in those patients who had eyes in which new breaks or detachments developed. The risk of visual loss was similar in those patients receiving prophylactic treatment compared with those not receiving treatment.

A monadic conjoint task was included in the survey, which varied frequency of administration (three, two, or one time per week for hemophilia A; twice weekly, weekly, or biweekly for hemophilia B, efficacy (no bleeding or breakthrough bleeding once every 4 months, 6 months, or 12 months, diluent volume (3 mL vs 2.5 mL for hemophilia A; 5 mL vs 3 mL for hemophilia B, vials per infusion (2 vs 1, reconstitution device (assembly required vs not, and manufacturer (established in hemophilia vs not. Respondents were asked their likelihood to switch from their current regimen to the presented treatment. Respondents were told to assume that other aspects of treatment, such as risk of inhibitor development, cost, and method of distribution, would remain the same. Results: A total of 89 patients and/or parents of children with hemophilia A participated; another 32 were included in the exercise for hemophilia B. Relative importance was 47%, 24%, and 18% for frequency of administration, efficacy, and manufacturer, respectively, in hemophilia A; analogous values were 48%, 26%, and 21% in

Few studies have evaluated the long-term effects of prophylactic ankle-brace use during a sport season. To determine the effects of prophylactic ankle-brace use during a high school basketball season on dynamic postural control and functional tests. Prospective repeated-measures design. High school athletic facility. 21 healthy high school basketball athletes (13 girls, 8 boys). The order of testing was randomized using the Star Excursion Balance Test (SEBT) for posteromedial (PM), medial (M), and anteromedial (AM) directions and 3 functional tests (FT) consisting of the single-leg crossover hop, single-leg vertical jump, and the single-leg 6-m hop for time at pre-, mid-, and postseason. After pretesting, the ankle brace was worn on both limbs during the entire 16-wk competitive basketball season. SEBT for PM, M, and AM and 3 single-leg FTs. Dynamic postural control using the SEBT and the 3 FTs improved over time, notably from pretest to posttest. The left limb was different from the right limb during the single-leg vertical jump. Effect sizes were large for pretest to posttest for the 3 SEBT directions and 2 of the 3 FTs. The 16-wk basketball prophylactic ankle-brace intervention significantly improved dynamic postural control and single-limb FTs over time.

Silodosin is a new selective therapy with a high pharmacologic selectivity for the α(1A)-adrenoreceptor. Our aim was to test silodosin's superiority to placebo and noninferiority to tamsulosin and discuss the findings in the context of a comprehensive literature review of the new compound silodosin. We conducted a multicenter double-blind, placebo- and active-controlled parallel group study. A total of 1228 men ≥50 yr of age with an International Prostate Symptom Score (IPSS) ≥13 and a urine maximum flow rate (Q(max)) >4 and ≤15 ml/s were selected at 72 sites in 11 European countries. The patients were entered into a 2-wk wash-out and a 4-wk placebo run-in period. A total of 955 patients were randomized (2:2:1) to silodosin 8 mg (n=381), tamsulosin 0.4 mg (n=384), or placebo (n=190) once daily for 12 wk. We calculated the change from baseline in IPSS total score (primary), storage and voiding subscores, quality of life (QoL) due to urinary symptoms, and Q(max). Responders were defined on the basis of IPSS and Q(max) by a decrease of ≥25% and an increase of ≥30% from baseline, respectively. The change from baseline in the IPSS total score with silodosin and tamsulosin was significantly superior to that with placebo (psilodosin and -2.0 (95% CI,-2.9, -1.1) with tamsulosin. Responder rates according to total IPSS were significantly higher (psilodosin (66.8%) and tamsulosin (65.4%) than with placebo (50.8%). Active treatments were also superior to placebo in the IPSS storage and voiding subscore analyses, as well as in QoL due to urinary symptoms. Of note, only silodosin significantly reduced nocturia versus placebo (the change from baseline was -0.9, -0.8, and -0.7 for silodosin, tamsulosin, and placebo, respectively; p=0.013 for silodosin vs placebo). An increase in Q(max) was observed in all groups. The adjusted mean change from baseline to end point was 3.77 ml/s for silodosin, 3.53 ml/s for tamsulosin, and 2.93 ml/s for placebo, but the change for

The role of prophylactic pelvic drainage in reducing the postoperative complication rate after rectal surgery remains unclear and controversial. This review and meta-analysis of prospective randomized controlled trials was performed to determine whether drainage of the extraperitoneal anastomosis after rectal surgery impacts the postoperative complication rate. Study eligibility criteria included randomized controlled trials comparing prophylactic pelvic drainage after rectal surgery. The Medline and Cochrane Trials Register databases were searched for prospective randomized controlled trials comparing drainage versus no drainage after rectal surgery. Studies published until December 2016 were included. The meta-analysis was performed using Review Manager 5.0 (Cochrane Collaboration, Oxford, UK). Three randomized controlled trials involving 660 patients with extraperitoneal anastomosis after rectal surgery (330 with and 330 without prophylactic pelvic drains) were included. The overall mortality rate was 0.7% (2/267) in the drain group and 1.9% (5/261) in the no-drain group (P = 0.900). The anastomotic leakage rate was 14.8% (49/330) in the drain group and 16.7% (55/330) in the no-drain group (P = 0.370). The postoperative small bowel obstruction rate was significantly higher in the drain than no-drain group (50/267, 18.7% vs. 33/261, 12.6%; odds ratio, 1.61; 95% confidence interval, 1.00-2.60; P = 0.050). Prophylactic use of pelvic drainage after extraperitoneal colorectal anastomosis has no impact on the incidence of anastomotic leakage or postoperative death. However, it significantly increases the rate of postoperative small bowel obstruction.

To evaluate the ways of reduction complications during endoscopic procedures based on principals of professional ethics and improving the quality of working area. Data of fundamental literature, evidence based medicine, science publications and internet portals. Deontology is the fundamental principle of medical practice and one of the main factors of professional effectiveness. Complications in endoscopy are often the investigations of deviation from the deontological principals. The whole number of psychological factors influences on professional activity of endoscopists, where the emotional "burn-out" syndrome (EBS) occupies one of the main places. Prophylactic and timely relief of EBS serves improvement of the practical work quality. Creation of favorable working area is the strategically important task in prophylactics of endoscopy complications. The questions of practical realization of deontological principles in endoscopy are the subject of further discussion.

2016-05-01

Full Text Available This article approaches the methodology of designing customized footwear for high arched foot. The authors propose to reconsider the classical structure of footwear bottom components for people with high arched foot and recommend incorporating custom components, with the role of compensation or adjustment. This study continues the authors’ research, starting from a foot’s 3D shape obtained by 3D scanning, the anthropometrical and biomechanical parameters, shoe lasts’ 3D modelling and continuing with 3D footwear design. Including customized orthosis can help to stop the evolution of abnormalities, diminishes sensations of pain during walking and improves performance in various physical activities carried out during the day, walking, running, and standing. The prophylactic footwear has to meet four main requirements: to protect the foot and ankle during walking and static; to ensure the normal resistance systems (bones, muscle and joint of the foot; to prevent the installation of irreversible structural changes by reducing stress on the foot; to contribute to increased performance in conducting regular physical activity. It is presented the steps of modelling an orthosis, a virtual simulation of its cutting process, followed by the integration and development of the insole, filling and sole for a customized shoe. Delcam Crispin CAD system and its applications for orthopaedics are used to design the bottom components of prophylactic footwear for a high arched foot.

[Cefamandole as prophylactic A.B. in abdominal surgery. Comparative study of cefamandole versus clindamycin/tobramycin (author's transl)].

Iarchy, J

1980-01-01

A prospective, randomized and controlled study of prophylactic A.B. was made in 100 patients prior to abdominal surgery. Fifty patients received 3 x 2 g of cefamandole I.V. within 24 hrs, the first dose being given at the time of anesthetic induction. Postoperative infections occurred in 2% of this group. Fifty patients received the association Clindamycin-Tobramycin (clindamycin 600 mg - tobramycin 80 mg/8 hrs) for 24 hrs, the first dose also at the induction of anesthesia. The complication rate in this group was 18%. The difference between those 2 groups is statistically significant (p less than 0.01). Cefamandole used as a prophylactic antibiotic in abdominal surgery reduces the incidence of postoperative wound infections when compared to the association clindamycin-tobramycin.

Current Evidence regarding Prophylactic Antibiotics in Head and Neck and Maxillofacial Surgery

Science.gov (United States)

2014-01-01

Antibiotic prophylaxis is commonly used to decrease the rate of infections in head and neck surgery. The aim of this paper is to present the available evidence regarding the application of antibiotic prophylaxis in surgical procedures of the head and neck region in healthy patients. A systemic literature review based on Medline and Embase databases was performed. All reviews and meta-analyses based on RCTs in English from 2000 to 2013 were included. Eight out of 532 studies fulfilled all requirements. Within those, only seven different operative procedures were analyzed. Evidence exists for the beneficial use of prophylactic antibiotics for tympanostomy, orthognathic surgery, and operative tooth extractions. Unfortunately, little high-level evidence exists regarding the use of prophylactic antibiotics in head and neck surgery. In numerous cases, no clear benefit of antibiotic prophylaxis has been shown, particularly considering their potential adverse side effects. Antibiotics are often given unnecessarily and are administered too late and for too long. Furthermore, little research has been performed on the large number of routine cases in the above-mentioned areas of specialization within the last few years, although questions arising with respect to the treatment of high-risk patients or of specific infections are discussed on a broad base.

Prophylactic ankle bracing is commonly used during physical activity. Understanding how bracing affects body mechanics is critically important when discussing both injury prevention and sport performance. The purpose is to determine if ankle bracing affects lower extremity mechanics during the Landing Error Scoring System test (LESS) and Sage Sway Index (SSI). Thirty physically active participants volunteered for this study. Participants completed the LESS and SSI in both a braced and unsupported conditions. Total errors were recorded for the LESS. Total errors and time (seconds) were recorded for the SSI. The Wilcoxon signed-rank test was utilized to evaluate any differences between the brace conditions for each dependent variable. A priori alpha level was set at pWilcoxon signed-rank test yielded no significant difference between the braced and unsupported conditions for the LESS (Z=-0.35, p=0.72), SSI time (Z=-0.36, p=0.72), or SSI Errors (Z=-0.37, p=0.71). Ankle braces had no effect on subjective clinical assessments of lower extremity alignment or postural stability. Utilization of a prophylactic support at the ankle did not substantially alter the proximal components of the lower kinetic chain. © Georg Thieme Verlag KG Stuttgart · New York.

Should prophylactic antibiotics be used routinely in epistaxis patients with nasal packs?

Science.gov (United States)

Nightingale, K; Patel, NN; Salib, RJ

2013-01-01

Introduction The current mainstream practice in otolaryngology departments relating to the use of prophylactic antibiotics in epistaxis patients requiring nasal packing is highly variable. This is due primarily to the lack of any validated guidelines. As such, we introduced a new treatment algorithm resulting in significant reduction of use in the systemic antibiotics, with emphasis instead on the use of topical antibiotics. The results were validated through a complete audit cycle. Methods A total of 57 patients undergoing nasal packing for spontaneous epistaxis were studied. Reaudit occurred after the implementation of new guidelines. Telephone surveys were conducted six weeks after hospital discharge, assessing infective nasal symptoms as well as rebleeding and readmission rates. Results Systemic antibiotic prescribing in anterior nasal packing fell by 58.2% between audit cycles with no statistically significant associated increase in infective nasal symptoms, rebleeding or readmission rates six weeks following hospital discharge. Conclusions Systemic prophylactic antibiotics are unnecessary in the majority of epistaxis patients with nasal packs. The use of topical antibiotics such as Naseptin® may be more appropriate, cheaper and as effective. Implementation of this treatment algorithm will help standardise systemic antibiotic usage in epistaxis patients with nasal packing and should reduce costs associated with unnecessary use of such medication.

Women who test positive for a BRCA1/2 mutation face difficult choices to manage their breast cancer risk; one of these choices is whether to opt for prophylactic mastectomy. Few data are available about this decision-making process. The current study provides data regarding the stability of risk-management preferences over time and the factors that are associated with these preferences. We analyzed data from 338 women who opted for breast cancer antigen (BRCA) testing. First, we prospectively assessed preferences of 80 BRCA mutation carriers at five different points in time ranging from 1 week after blood sampling up to 9 months after BRCA-test disclosure. Second, we applied univariate and multivariate regression analyses to examine which medical, sociodemographic, and psychological factors are related to a preference for prophylactic mastectomy. Ninety percent of the women already indicated a preference regarding risk management at baseline. Moreover, most women had stable preferences over time. Furthermore, anticipated feelings of regret in case of a hypothetical breast cancer diagnosis in the near future were strongly related to risk-management preference (odds ratio = 8.93; P preferences. Many of them may be sensitive to the possibility of regret in case of a bad outcome. We discuss whether possible regret in the future is a rational reason for opting for prophylactic mastectomy, or whether it signifies an emotional coping process or strategy in which the future costs are no longer fully considered.

There are several Cochrane systematic reviews looking at postpartum haemorrhage (PPH) prophylaxis in the third stage of labour and another Cochrane review investigating the timing of prophylactic uterotonics in the third stage of labour (i.e. before or after delivery of the placenta). There are, however, no Cochrane reviews looking at the use of interventions given purely after delivery of the placenta. Ergometrine or methylergometrine are used for the prevention of PPH in the postpartum period (the period after delivery of the infant) after delivery of the placenta in some countries. There are, furthermore, no Cochrane reviews that have so far considered herbal therapies or homeopathic remedies for the prevention of PPH after delivery of the placenta. To assess the effectiveness of available prophylactic interventions for PPH including prophylactic use of ergotamine, ergometrine, methylergometrine, herbal therapies, and homeopathic remedies, administered after delivery of the placenta, compared with no uterotonic agents as well as with different routes of administration for prevention of PPH after delivery of the placenta. We searched the Cochrane Pregnancy and Childbirth Group's Trials Register (30 April 2013), The Food and Drug Administration (FDA) (USA),  Medicines and Healthcare Products Regulatory Agency (MHRA) (UK), European Medicines Agency (EMA) (EU), Pharmaceuticals and Medical Devices Agency (PMDA) (Japan),  Therapeutic Goods Administration (TGA) (Australia), ClinicalTrials.gov, Current Controlled Trials, WHO International Clinical Trials Registry Platform (ICTRP), University Hospital Medical Information Network Clinical Trials Registry (UMIN-CTR; Japan), Japan Pharmaceutical Information Center Clinical Trials Information (Japic-CTI; Japan), Japan Medical Association Clinical Trial Registration (JMACCT CTR; Japan) (all on 30 April 2013) and reference lists of retrieved studies All randomised or quasi-randomised controlled trials comparing prophylactic

Prophylactic mastectomy is an effective risk-reducing option in women with hereditary increased risk of breast cancer. It may be combined with immediate reconstruction, with the intention of improving aesthetic outcome and health-related quality of life. Sixty-one women underwent prophylactic mastectomy and immediate breast reconstruction in Malmö, Sweden, between 1995 and 2003. Forty women underwent bilateral prophylactic mastectomy and immediate reconstruction. Ten of these had a previous breast cancer diagnosis. Twenty-one women underwent contralateral prophylactic mastectomy and immediate reconstruction after a previous breast cancer. Fifty-four of the women (89%) were evaluated clinically for aesthetic results and complications. Patient satisfaction and quality of life were evaluated with one study-specific and two standardised health-related questionnaires administered at time of clinical follow-up. Median follow-up time was 42 months (range 7-99 months). The position of the reconstructed breasts was judged as satisfactory in 77% of breasts. Symmetry in relation to the midline was adequate in 89% of breasts. A capsular contracture grade III according to Baker and indentation tonometry was observed in 1% of breasts (1/104). The complication rate was 18% (7% early and 11% late). Secondary corrections were carried out in 11% of breasts. The study-specific questionnaire revealed a high degree of satisfaction. No woman regretted the procedure, and all women would have chosen the same type of surgery again. An age-stratified comparison of Swedish women using the Short Form 36 Health Survey Questionnaire (SF-36) questionnaire was carried out for this study. The study population scores were high, suggesting that prophylactic mastectomy and immediate reconstruction on both physical and psychological issues in this retrospective study had no negative effect. Also, the Hospital Anxiety and Depression Scale (HAD) questionnaire did not suggest any increased anxiety or

This study was designed to: (i) evaluate the effect of amnioinfusion on the latency period in patients with oligohydramnios for preterm premature rupture of membranes, and (ii) to investigate the relationship between changes in the amniotic fluid index and fetal heart rate short-term variability by computerized Hewlett-Packard cardiotocography, longitudinally estimated before and after prophylactic amnioinfusion. All singleton pregnancies with prolonged premature rupture of membranes after 25 weeks of gestation and seen at the Institute of Obstetrics and Gynecology, University of Ancona (Italy), between January 1994 and June 1995 were included in the study. Transabdominal amnioinfusion with 150-350 ml warmed normal saline (25-50 ml/min) was performed at weekly intervals. Amniotic fluid volume was assessed ultrasonographically by means of the four-quadrant technique on a weekly basis before and after each amnioinfusion, as well as the short-term variability by a Hewlett-Packard computerized cardiotocographic system. 18 women were enrolled and underwent prophylactic transabdominal amnioinfusion at weekly intervals until delivery. Eighteen controls, who did not undergo prophylactic amnioinfusion, were recruited from our 1992-1993 series and included in the study. The median interval between premature rupture of membranes and delivery was 3.0 weeks (range 1-8 weeks), with an average delivery age of 33.0 weeks (range 27-36 weeks). The latency period was significantly longer in patients who underwent prophylactic amnioinfusion (mean +/- SD, 4.1 +/- 1.7 weeks) than in controls(1.7 +/- 1.0 weeks; p amnioinfusion. A direct relationship was observed between the amniotic fluid index and short-term variability (linear regression analysis r = 0.54, p = 0.04). The mean values of fetal movements recorded by computerized tomography during the 20 min of observation significantly increased after amnioinfusion in comparison with those before it (2.6 +/- 0.9 and 0.9 +/- 0

We have examined the value of prophylactic epilepsy surgery in diseases leading to intractable epilepsy. We reviewed 11 glioneuronal tumors (GNT) including gangliogliomas and dysembryoplastic neuroepithelial tumors, 11 cortical dysplasia (CD), and 33 cavernous angiomas (CA) diagnosed with MRI between the years 2000 and 2008 at the Department of Neurosurgery of Juntendo University in this study. We analyzed retrospectively the followings. Age of seizure onset and seizure severity. Region of each disease leading to intractable epilepsy. Seizure outcome after the surgery. Surgical morbidity. Ages of seizure onset of GNT, CD, and CA were 21.0±12.1, 1.3±7.5, 24.8±18.1 years, respectively. 81.8% of CD and GNT were intractable, however CA progresses to intractable epilepsy in 48.5%. The 66.7% of GNT with intractable seizures located in the mesial temporal lobe and 66.7% of CD had entra-temporal location. CA located in the mesial temporal lobe progressed to intractable epilepsy in 80%. Seizure free ratios of GNT, CD, and CA were 87.5%, 50.0%, 81.3%, respectively. In CDs where was impossible to carry out complete resection resulted in residual seizures. Neurological sequelae after surgery were observed in 3 cases. Morbidity ratios of motor weakness, speech difficulty, and memory disturbances are 4.6%, 4.6%, 2.3%, respectively. Majority of CD, GNT, and CA located in the mesial temporal lobe progress towards intractable epilepsy. Prophylactic epilepsy surgery by experienced surgeon with low complication rates can be an acceptable alternative for these pathological conditions. Seizure outcome of surgery for CD does not reach the success rates of those in GNT and CA. The cause of the unfavorable result in CD is the inapplicability to eloquent areas. Aggressive early surgery for CD may improve outcome considering neuronal plasticity of childhood. (author)

Equine sarcoids are highly recurrent bovine papillomavirus (BPV)-induced fibroblastic neoplasms that are the most common skin tumours in horses. In order to facilitate the study of potential equine sarcoid prophylactics or therapeutics, which can be a slow and costly process in equines, a murine model for BPV-1 protein-expressing equine sarcoid-like tumours was developed in mice through stable transfection of BPV-1 E5 and E6 in a murine fibroblast tumour cell line (K-BALB). Like equine sarcoids, these murine tumour cells (BPV-KB) were of fibroblast origin, were tumorigenic and expressed BPV-1 proteins. As an initial investigation of the preclinical potential of this tumour model for equine sarcoids prophylactics, mice were immunized with BPV-1 E5E6 Venezuelan equine encephalitis virus replicon particles, prior to BPV-KB challenge, which resulted in an increased tumour-free period compared with controls, indicating that the BPV-KB murine model may be a valuable preclinical alternative to equine clinical trials.

AIMS: ICD implantation for primary prevention of sudden cardiac death in patients with left ventricular systolic dysfunction (ejection fraction <\\/= 35%) has increased since the publication of the SCD-HEFT and MADIT-II data. The aim of this study is to examine the effectiveness and safety of prophylactic ICD use in a community heart failure population and to assess the impact on patient\\'s quality of life. METHODS AND RESULTS: Seventy-one ICDs were inserted between the years 2002 and 2006. The mean follow-up from time of insertion was 24 +\\/- 11 months. Eighteen patients (25%) had potentially life-saving therapy. Seven (10%) patients received inappropriate shocks. Complications were encountered in five patients (7%). CONCLUSION: In a community heart failure population, prophylactic ICD implantation is associated with a high incidence of life-saving therapy, a low complication rate and a high level of tolerability. These data indicate translation of clinical trial benefits to the general heart failure population.

Growth and weight gain were studied longitudinally over a period of four years in thirty-nine children treated for acute lymphoblastic leukemia. The children were divided into two groups according to treatment. Twenty-eight children were given prophylactic cranial irradiation and eleven children were treated without such irradiation. The duration of cytostatic treatment was three years in all cases. Average growth during the first two years was similar in the two groups, and the standard deviation scores (SDS) were below average. The rate of growth during the fourth year was significantly higher among those children who had not received cranial irradiation. After four years the average attained height had declined 0.5 SD for children treated with cranial irradiation and 0.2 SD for children without such treatment. Attained weight after four years had increased 0.4 SD more among those children who had not received irradiation. The results suggest that prophylactic cranial irradiation is responsible for the greater part of the prepubertal growth inhibition in these children. (authors)

The authors report a study which aimed at determining the benefit of a brain prophylactic irradiation for patients suffering from a localized small-cell bronchial cancer and in partial response to the local-regional treatment of their disease. A retrospective analysis has been performed on a set of 289 patients who had been treated by chemo-radiotherapy with or without brain prophylactic irradiation between 1981 and 2007. Data are discussed in terms of remission level, survival with respect to the level of response to the local-regional treatment. Depending on this response level the irradiation increases or not the probability of global survival, or the probability of specific survival. Short communication

Kawamori, Jiro; Kamata, Rikisaburo; Sanuki, Eiichi

1993-01-01

Between 1967 and 1988, 102 patients with Stage T1-2N0 squamous cell carcinoma of the tongue were treated with uneven fractional irradiation therapy (intra-oral electron beam irradiation with and without prophylactic ipsilateral upper neck irradiation at the Dept. of Radiology, Nihon University School of Medicine. Of 102 primary lesions, 89 cases were controlled with this therapy. In this study, these 89 cases were investigated in order to analyze the prophylactic effect of upper neck irradiation. Of the 89 patients, 42 received only intra-oral electron beam irradiation, while the remaining 47 received a combination of intra-oral electron beam irradiation and prophylactic irradiation to the ipsilateral upper neck. Twenty three of the 89 (25.8%) developed metastasis to the neck after the radiotherapy. A breakdown of these 23 cases reveals that 3/21 (14.3%) received 40-50 Gy to the neck, 9/26 (34.6%) received 20-40 Gy to the neck, and 11/42 (26.2%) received no irradiation to the neck (p<0.05 between first and second groups, and between first and third groups). The neck metastasis was classified into one of three categories based on the region in which it first appeared (ipsilateral upper neck, ipsilateral lower neck or contralateral neck). The first metastasis was seen in the ipsilateral upper neck, in the ipsilateral lower neck and in the contralateral neck in 17, 4 and 2 patients, respectively. In 1/19 who had received 40-50 Gy, in 5/21 who had received 20-40 Gy and in 11/42 who had not received neck irradiation the first metastasis appeared in the ipsilateral upper neck. The five year survival rate was 94%, 75% and 85% in the patients receiving 40-50 Gy, 20-40 Gy and no neck irradiation, respectively. These results suggest that prophylactic irradiation of 40-50 Gy to the ipsilateral upper neck might decrease the incidence of neck metastasis and slightly prolong survival time. (author)

This study aims to evaluate the effect of the prophylactic continuous positive airway pressure (CPAP) administration in the delivery room to newborns who were delivered by elective cesarean section (CS). Inborn infants with gestational age between 34(0/7) to 38(6/7) and born by elective CS were prospectively randomized to receive either prophylactic CPAP for 20 minutes via face mask or standardized care without CPAP in the delivery room. Primary outcomes were the incidence of transient tachypnea of the newborn (TTN) and neonatal intensive care unit (NICU) admission due to respiratory distress. A total of 259 infants with a mean gestational age of 37.7 ± 0.8 weeks and birth weight of 3,244 ± 477 g were included. A total of 134 infants received prophylactic CPAP and 125 received control standard care. The rate of NICU admission was significantly lower in prophylactic CPAP group (p = 0.045). Although the rate of TTN was lower in the prophylactic CPAP group, the difference was not statistically significant (p = 0.059). The rate of NICU admission due to respiratory distress was significantly higher in late-preterm cohort than early-term cohort (p CPAP administration decreases the rate of NICU admission without any side effect in late-preterm and early-term infants delivered by elective CS.

2014-12-01

The aim of this meta-analysis was to investigate whether there are any positive effects of prophylactic antibiotic regimen on implant failure rates and post-operative infection when performing dental implant treatment in healthy individuals. An electronic search without time or language restrictions was undertaken in March 2014. Eligibility criteria included clinical human studies, either randomised or not. The search strategy resulted in 14 publications. The I(2) statistic was used to express the percentage of the total variation across studies due to heterogeneity. The inverse variance method was used with a fixed- or random-effects model, depending on the heterogeneity. The estimates of relative effect were expressed in risk ratio (RR) with 95% confidence interval. Six studies were judged to be at high risk of bias, whereas one study was considered at moderate risk, and six studies were considered at low risk of bias. The test for overall effect showed that the difference between the procedures (use versus non-use of antibiotics) significantly affected the implant failure rates (P = 0.0002), with a RR of 0.55 (95% CI 0.41-0.75). The number needed to treat (NNT) to prevent one patient having an implant failure was 50 (95% CI 33-100). There were no apparent significant effects of prophylactic antibiotics on the occurrence of post-operative infections in healthy patients receiving implants (P = 0.520). A sensitivity analysis did not reveal difference when studies judged as having high risk of bias were not considered. The results have to be interpreted with caution due to the presence of several confounding factors in the included studies. © 2014 John Wiley & Sons Ltd.

International guidelines recommend the use of a prophylactic antibiotic before the peritoneal dialysis (PD) catheter can be inserted. The main objective of this study was to assess whether this practice is associated with a lower risk of early peritonitis and to estimate the magnitude of the centre effect. A retrospective, multi-centric study was conducted, in which data from the French Language Peritoneal Dialysis Registry was analysed. Patients were separated into 2 groups based on whether or not prophylactic antibiotics were used prior to catheter placement. Out of the 2,014 patients who had a PD catheter placed between February 1, 2012 and December 31, 2014, 1,105 were given a prophylactic antibiotic. In a classical logit model, the use of prophylactic antibiotics was found to protect the individual against the risk of early peritonitis (OR 0.67, 95% CI 0.49-0.92). However, this association lost significance in a mixed logistic regression model with centre as a random effect: OR 0.73 (95% CI 0.48-1.09). Covariates associated with the risk of developing early peritonitis were age over 65: OR 0.73 (95% CI 0.39-0.85), body mass index over 35 kg/m2: OR 1.99 (95% CI 1.13-3.47), transfer to PD due to graft failure: OR 2.24 (95% CI 1.22-4.11), assisted PD: OR 1.96 (95% CI 1.31-2.93), and the use of the Moncrief technique: OR 3.07 (95% CI 1.85-5.11). There is a beneficial effect of prophylactic antibiotic used prior to peritoneal catheter placement, on the occurence of early peritonitis. However, the beneficial effect could be masked by a centre effect. © 2016 S. Karger AG, Basel.

Padula, William V

The purpose of this study was to examine the effectiveness and value of prophylactic 5-layer foam sacral dressings to prevent hospital-acquired pressure injury rates in acute care settings. Retrospective observational cohort. We reviewed records of adult patients 18 years or older who were hospitalized at least 5 days across 38 acute care hospitals of the University Health System Consortium (UHC) and had a pressure injury as identified by Patient Safety Indicator #3 (PSI-03). All facilities are located in the United States. We collected longitudinal data pertaining to prophylactic 5-layer foam sacral dressings purchased by hospital-quarter for 38 academic medical centers between 2010 and 2015. Longitudinal data on acute care, hospital-level patient outcomes (eg, admissions and PSI-03 and pressure injury rate) were queried through the UHC clinical database/resource manager from the Johns Hopkins Medicine portal. Data on volumes of dressings purchased per UHC hospital were merged with UHC data. Mixed-effects negative binomial regression was used to test the longitudinal association of prophylactic foam sacral dressings on pressure injury rates, adjusted for hospital case-mix and Medicare payments rules. Significant pressure injury rate reductions in US acute care hospitals between 2010 and 2015 were associated with the adoption of prophylactic 5-layer foam sacral dressings within a prevention protocol (-1.0 cases/quarter; P = .002) and changes to Medicare payment rules in 2014 (-1.13 cases/quarter; P = .035). Prophylactic 5-layer foam sacral dressings are an effective component of a pressure injury prevention protocol. Hospitals adopting these technologies should expect good value for use of these products.

Cyanide inhibits cytochrome c oxidase, the terminal oxidase of the mitochondrial respiratory pathway, therefore inhibiting the cell oxygen utilization and resulting in the condition of histotoxic anoxia. The enzyme rhodanese detoxifies cyanide by utilizing sulfur donors to convert cyanide to thiocyanate, and new and improved sulfur donors are actively sought as researchers seek to improve cyanide prophylactics. We have determined brain cytochrome c oxidase activity as a marker for cyanide exposure for mice pre-treated with various cyanide poisoning prophylactics, including sulfur donors thiosulfate (TS) and thiotaurine (TT3). Brain mitochondria were isolated by differential centrifugation, the outer mitochondrial membrane was disrupted by a maltoside detergent, and the decrease in absorbance at 550 nm as horse heart ferrocytochrome c (generated by the dithiothreitol reduction of ferricytochrome c) was oxidized was monitored. Overall, the TS control prophylactic treatment provided significant protection of the cytochrome c oxidase activity. The TT3-treated mice showed reduced cytochrome c oxidase activity even in the absence of cyanide. In both treatment series, addition of exogenous Rh did not significantly enhance the prevention of cytochrome c oxidase inhibition, but the addition of sodium nitrite did. These findings can lead to a better understanding of the protection mechanism by various cyanide antidotal systems. Copyright © 2011 John Wiley & Sons, Ltd.

Surgical site infections with elective laparoscopic cholecystectomy are less frequent and less severe, leading some to suggest that prophylactic antibiotics (PA) are no longer indicated. We compared the incidence of surgical site infections before and after an institutional practice change of withholding PA for elective laparoscopic cholecystectomy. Between May 7, 2013, and March 11, 2015, no PA were given to patients selected for elective cholecystectomy by two surgeons at a single center. The only patients excluded were those who received antibiotics before surgery for any reason. All others, including those at high risk for infection, were included. The incidence and severity of infections were compared with historical controls treated with prophylaxis by the same two surgeons from November 6, 2011, to January 13, 2013. There were 268 patients in the study group and 119 patients in the control group. Infection occurred in 3.0 per cent in the study group compared with 0.9 per cent in the controls (P = 0.29). All infections were mild except one. Based on these data, the routine use of PA for elective laparoscopic cholecystectomy is not supported.

The prophylactic reduction of aluminium intake.

Lione, A

1983-02-01

The use of modern analytical methods has demonstrated that aluminium salts can be absorbed from the gut and concentrated in various human tissues, including bone, the parathyroids and brain. The neurotoxicity of aluminium has been extensively characterized in rabbits and cats, and high concentrations of aluminium have been detected in the brain tissue of patients with Alzheimer's disease. Various reports have suggested that high aluminium intakes may be harmful to some patients with bone disease or renal impairment. Fatal aluminium-induced neuropathies have been reported in patients on renal dialysis. Since there are no demonstrable consequences of aluminium deprivation, the prophylactic reduction of aluminium intake by many patients would appear prudent. In this report, the major sources of aluminium in foods and non-prescription drugs are summarized and alternative products are described. The most common foods that contain substantial amounts of aluminium-containing additives include some processed cheeses, baking powders, cake mixes, frozen doughs, pancake mixes, self-raising flours and pickled vegetables. The aluminium-containing non-prescription drugs include some antacids, buffered aspirins, antidiarrhoeal products, douches and haemorrhoidal medications. The advisability of recommending a low aluminium diet for geriatric patients is discussed in detail.

Ebola outbreaks occur on a frequent basis, with the 2014-2015 outbreak in West Africa being the largest one ever recorded. This outbreak has resulted in over 11,000 deaths in four African countries and has received international attention and intervention. Although there are currently no approved therapies or vaccines, many promising candidates are undergoing clinical trials, and several have had success in promoting recovery from Ebola. However, these prophylactics and therapeutics have been designed and tested only against the same species of Ebola virus as the one causing the current outbreak. Future outbreaks involving other species would require reformulation and possibly redevelopment. Therefore, a broad-spectrum alternative is highly desirable. We have found that a flavonoid derivative called quercetin 3-β-O-d-glucoside (Q3G) has the ability to protect mice from Ebola even when given as little as 30 min prior to infection. Furthermore, we have demonstrated that this compound targets the early steps of viral entry. Most promisingly, antiviral activity against two distinct species of Ebola virus was seen. This study serves as a proof of principle that Q3G has potential as a prophylactic against Ebola virus infection. Copyright © 2016, American Society for Microbiology. All Rights Reserved.

Accumulation of amyloid beta-peptide (Aβ) in the brain is hypothesized to be a causal event leading to dementia in Alzheimer's disease (AD). Aβ vaccination removes Aβ deposits from the brain. Aβ immunotherapy, however, may cause T cell- and/or Fc-receptor-mediated brain inflammation and relocate parenchymal Aβ deposits to blood vessels leading to cerebral hemorrhages. Because catalytic antibodies do not form stable immune complexes and Aβ fragments produced by catalytic antibodies are less likely to form aggregates, Aβ-specific catalytic antibodies may have safer therapeutic profiles than reversibly-binding anti-Aβ antibodies. Additionally, catalytic antibodies may remove Aβ more efficiently than binding antibodies because a single catalytic antibody can hydrolyze thousands of Aβ molecules. We previously isolated Aβ-specific catalytic antibody, IgVL5D3, with strong Aβ-hydrolyzing activity. Here, we evaluated the prophylactic and therapeutic efficacy of brain-targeted IgVL5D3 gene delivery via recombinant adeno-associated virus serotype 9 (rAAV9) in an AD mouse model. One single injection of rAAV9-IgVL5D3 into the right ventricle of AD model mice yielded widespread, high expression of IgVL5D3 in the unilateral hemisphere. IgVL5D3 expression was readily detectable in the contralateral hemisphere but to a much lesser extent. IgVL5D3 expression was also confirmed in the cerebrospinal fluid. Prophylactic and therapeutic injection of rAAV9-IgVL5D3 reduced Aβ load in the ipsilateral hippocampus of AD model mice. No evidence of hemorrhages, increased vascular amyloid deposits, increased proinflammatory cytokines, or infiltrating T-cells in the brains was found in the experimental animals. AAV9-mediated anti-Aβ catalytic antibody brain delivery can be prophylactic and therapeutic options for AD.

Background Platelet transfusions are used in modern clinical practice to prevent and treat bleeding in thrombocytopenic patients with bone marrow failure. Although considerable advances have been made in platelet transfusion therapy in the last 40 years, some areas continue to provoke debate, especially concerning the use of prophylactic platelet transfusions for the prevention of thrombocytopenic bleeding. This is an update of a Cochrane review first published in 2004 and updated in 2012 that addressed four separate questions: therapeutic-only versus prophylactic platelet transfusion policy; prophylactic platelet transfusion threshold; prophylactic platelet transfusion dose; and platelet transfusions compared to alternative treatments. We have now split this review into four smaller reviews looking at these questions individually; this review is the first part of the original review. Objectives To determine whether a therapeutic-only platelet transfusion policy (platelet transfusions given when patient bleeds) is as effective and safe as a prophylactic platelet transfusion policy (platelet transfusions given to prevent bleeding, usually when the platelet count falls below a given trigger level) in patients with haematological disorders undergoing myelosuppressive chemotherapy or stem cell transplantation. Search methods We searched for randomised controlled trials (RCTs) in the Cochrane Central Register of Controlled Trials (Cochrane Library 2015, Issue 6), MEDLINE (from 1946), Embase (from 1974), CINAHL (from 1937), the Transfusion Evidence Library (from 1950) and ongoing trial databases to 23 July 2015. Selection criteria RCTs involving transfusions of platelet concentrates prepared either from individual units of whole blood or by apheresis, and given to prevent or treat bleeding in patients with malignant haematological disorders receiving myelosuppressive chemotherapy or undergoing HSCT. Data collection and analysis We used standard methodological procedures

Sickle cell anemia is associated with an alarming attrition rate during pregnancy. The maternal morbidity rate, perinatal wastage rate, and the incidence of severe morbidity in both mother and child are elevated above acceptable limits. In most cases, these statistics have been compiled using conservative therapeutic modalities. In contrast, this report utilizes prophylactic partial exchange transfusion therapy in patients with severe sickle cell hemoglobinopathies. The protocol involves the introduction of 750-1000 cc of buffy coat, poor washed red cells exchanged with 1000-1500 cc whole blood during phlebotomy at 28 weeks' gestation and again prior to term. Thirty-six consecutive pregnant patients with sickle cell anemia have been managed in this fashion. The one maternal mortality occurred in a patient who did not complete the protocol. Major maternal morbidity and perinatal wastage rates were significantly decreased. Two cases of serum hepatitis occurred. It appears from these data that the use of prophylactic partial exchange transfusion in pregnant patients with severe sickle cell hemoglobinopathies can be of benefit. Further trials of this method seem justified by these results to assess completely the benefit-risk ratio of this procedure.

PurposeTo appraise the efficacy and safety of prophylactic uterine artery embolization in pregnancy termination with placenta previa.MethodsA cohort of 54 consecutive patients with placenta previa underwent prophylactic uterine artery embolization before vaginal delivery from February 2012 to March 2015. Vaginal delivery was attempted in all patients. Cesarean section or hysterectomy was introduced when vaginal delivery failed.ResultsVaginal delivery succeeded in 50 patients (93.6%) and failed in 4 patients (6.4%), thereupon converted to cesarean delivery. No patients resorted to hysterectomy. Six patients (11.1%) underwent blood transfusion. None of clinical characteristics, including maternal age, gestational age, history of abortion, history of cesarean delivery, and volume of vaginal bleeding, was significantly associated with complete placenta previa (P > 0.05). However, patients with complete placenta previa had a significantly lower successful rate of vaginal delivery than did patients without complete placenta previa (81 vs 100%, P = 0.038). The rate of complications was 3.7%. No major complications were observed.ConclusionUterine artery embolization is an effective and safe technique to assist pregnancy termination with placenta previa, which may lower the risk of cesarean section, hysterectomy, and blood transfusion.

Clinically significant bleeding (CSPEB) is the most common adverse event following endoscopic mucosal resection (EMR) of large sessile and laterally spreading colorectal lesions (LSLs), and is associated with morbidity and resource utilization. CSPEB occurs more frequently with proximal LSLs. Prophylactic clipping of the post-EMR defect may be beneficial in CSPEB prevention. The aim of this study was to determine the cost-effectiveness of a prophylactic clipping strategy. We hypothesized that prophylactic clipping in the proximal colon was cost-effective. An economic model was applied to outcomes from the Australian Colonic Endoscopic Mucosal Resection (ACE) Study. Clip distances of 3, 5, 8, and 10 mm were analyzed. The cost of treating CSPEB was determined from an independent costing agency. The funds needed to spend (FNS) was the cost incurred in order to prevent one episode of CSPEB. A break-even analysis was performed to determine cost equivalence of the costs of clipping and CSPEB. Outcomes of 1717 LSLs (mean size 35.8 mm; 52.6 % proximal colon) that underwent EMR were analyzed. The overall rate of CSPEB was 6.4 % (proximal 8.9 %; distal 3.7 %). Endoscopic management was required in 45 % of CSPEB episodes. With a clip distance of 3 mm, the expected cost of prophylactic clipping was € 1106 per lesion compared with € 157 per lesion for the expected cost of CSPEB without clipping. At 100 % clipping efficacy, the FNS was € 14 826 (proximal and distal lesions € 9309 and € 29 540, respectively). A clip price of € 10.35 was required for the cost of clipping to offset the cost of CSPEB. A prophylactic clipping strategy is not cost-effective and at present cannot be justified for all lesions or selectively for lesions in the proximal colon.

Recent research indicates that xerostomia caused by irradiation of the salivary glands causes rampant caries by inducing a soft sucrose rich diet in this group of patients and by reduction of the buffer capacity and volume of the secretion. Whereas total extraction of the teeth before the irradiation started was previously the normal procedure in these patients, the teeth now can be maintained by very simple and inexpensive prophylactic measures, involving use of a gel containing 1% of soldium fluoride for 5 minutes once daily.

New class of monoclonal antibodies against severe influenza: prophylactic and therapeutic efficacy in ferrets.

Robert H E Friesen

2010-02-01

Full Text Available The urgent medical need for innovative approaches to control influenza is emphasized by the widespread resistance of circulating subtype H1N1 viruses to the leading antiviral drug oseltamivir, the pandemic threat posed by the occurrences of human infections with highly pathogenic avian H5N1 viruses, and indeed the evolving swine-origin H1N1 influenza pandemic. A recently discovered class of human monoclonal antibodies with the ability to neutralize a broad spectrum of influenza viruses (including H1, H2, H5, H6 and H9 subtypes has the potential to prevent and treat influenza in humans. Here we report the latest efficacy data for a representative antibody of this novel class.We evaluated the prophylactic and therapeutic efficacy of the human monoclonal antibody CR6261 against lethal challenge with the highly pathogenic avian H5N1 virus in ferrets, the optimal model of human influenza infection. Survival rates, clinically relevant disease signs such as changes in body weight and temperature, virus replication in lungs and upper respiratory tract, as well as macro- and microscopic pathology were investigated. Prophylactic administration of 30 and 10 mg/kg CR6261 prior to viral challenge completely prevented mortality, weight loss and reduced the amount of infectious virus in the lungs by more than 99.9%, abolished shedding of virus in pharyngeal secretions and largely prevented H5N1-induced lung pathology. When administered therapeutically 1 day after challenge, 30 mg/kg CR6261 prevented death in all animals and blunted disease, as evidenced by decreased weight loss and temperature rise, reduced lung viral loads and shedding, and less lung damage.These data demonstrate the prophylactic and therapeutic efficacy of this new class of human monoclonal antibodies in a highly stringent and clinically relevant animal model of influenza and justify clinical development of this approach as intervention for both seasonal and pandemic influenza.

Inactivating mutations in the CDH1 (E-cadherin) gene are the predisposing cause of gastric cancer in most families with hereditary diffuse gastric cancer (HDGC). The lifetime risk of cancer in mutation positive members is more than 80 % and prophylactic total gastrectomy is recommended. Not all...... mutations in the CDH1 gene are however pathogenic and it is important to classify mutations before this major operation is performed. Probands from two Danish families with gastric cancer and a history suggesting HDGC were screened for CDH1 gene mutations. Two novel CDH1 gene mutations were identified....... Hospital stay was 6-8 days and there were no complications. Small foci of diffuse gastric cancer were found in all patients-intramucosal in six and advanced in one. Preoperative endoscopic biopsies had revealed a microscopic cancer focus in two of the patients. Our data confirmed the pathogenic nature...

2014-06-01

A half billion people have genital herpes infections worldwide. Approximately one-fifth of American women between ages 14 and 49 are HSV-2 seropositive. The development of an effective genital herpes vaccine is a global health necessity based on the mental anguish genital herpes causes for some individuals, the fact that pregnant women with genital herpes risk transmitting infection to their newborn children, and the observation that HSV-2 infection is associated with a 3-fold to 4-fold increased probability of HIV acquisition. We review the strengths and limitations of preclinical animal models used to assess genital herpes vaccine candidates and the goals of prophylactic and therapeutic vaccines. We also discuss the current pipeline of vaccine candidates and lessons learned from past clinical trials that serve as a stimulus for new strategies, study designs and endpoint determinations.

To investigate the effectiveness and safety of prophylactic surgical ligation of patent ductus arteriosus (PDA) on mortality and morbidity of preterm infants weighing less than 1000 g at birth. The study conducted a systematic search of available database from 1996-2008. Retrieved articles were assessed for eligibility and data was abstracted independently by two reviewers. Decisions to include studies for review and the methodological quality of included studies were asssessed in duplicate based on predetermined criteria. No language restrictions were applied. Only one eligible study that enrolled 84 extremely low birth weight infants was identified. Prophylactic surgical ligation of PDA resulted in a statistically significant reduction of severe stage II or III necrotizing enterocolitis, [RR 0.25, 95% CI (0.08, 0.83), P value 0.02, number needed to treat 5]. The study, however, found no statistically significant difference in mortality, intraventricular hemorrhage, bronchopulmonary dysplasia, and retinopathy of prematurity. Current evidence does not support the use of prophylactic surgical ligation of PDA in the management of the preterm infants

We have conducted a case-control study in order to assess whether prophylactic administration of Saccharomyces boulardii (S. boulardii prevents occurrence of AAD among adult hospitalized patients. Methods. Single-center hospital based case-control study was conducted in University Clinic “Dr Dragisa Misovic-Dedinje”, Belgrade, Serbia. Hospital records were screened in order to identify all the patients developing AAD in period January 1. 2010 – August 31. 2015. For every case, one age and gender matched control was randomly selected among patients hospitalized at the same time at the same department who were administered with antibiotics and did not develop AAD. For both cases and controls data were extracted on demographics, medical history, indication for use of antibiotics, antibiotics used, and prophylactic use of S.boulardii probiotics. The relationship between occurrence of AAD and putative risk factors were measured using the odds ratios (ORs and their 95% confidence interval (CI derived from logistic regression analysis. Results. Number of 59 cases and 59 controls were included in the study. Most of AAD cases were associated with old age (mean age of 78.05, and almost half (49.15% were hospitalized on geriatrics department. Most prescribed class of antibiotics among cases was III generation cephalosporins (50.85%, followed by fluoroquinolones (28.81% and trimethoprim-sulfamethoxazole (20.34%. Significantly more cases than controls were treated with carbapenems (16.95% vs. 5.08% respectively, p=0.04. Significantly less cases were administered with prophylactic S. boulardii probiotics (18.64% vs. 42.37% p=0.005. We identified prophylactic use of S. boulardii to act protectively against development of AAD from both univariate (OR: 0.31, 95% CI: 0.14-0.72 and multivariate analysis (OR:0.36, 95% CI: 0.14-0.80.

Purpose: The purpose of the present study was to evaluate the prophylactic effect of hyperbaric oxygen (HBO) therapy for radiation-induced brain injury in patients with brain metastasis treated with stereotactic radiosurgery (SRS). Methods and Materials: The data of 78 patients presenting with 101 brain metastases treated with SRS between October 1994 and September 2003 were retrospectively analyzed. A total of 32 patients with 47 brain metastases were treated with prophylactic HBO (HBO group), which included all 21 patients who underwent subsequent or prior radiotherapy and 11 patients with common predictors of longer survival, such as inactive extracranial tumors and younger age. The other 46 patients with 54 brain metastases did not undergo HBO (non-HBO group). Radiation-induced brain injuries were divided into two categories, white matter injury (WMI) and radiation necrosis (RN), on the basis of imaging findings. Results: Radiation-induced brain injury occurred in 5 lesions (11%) in the HBO group (2 WMIs and 3 RNs) and in 11 (20%) in the non-HBO group (9 WMIs and 2 RNs). The WMI was less frequent for the HBO group than for the non-HBO group (p = 0.05), although multivariate analysis by logistic regression showed that WMI was not significantly correlated with HBO (p = 0.07). The 1-year actuarial probability of WMI was significantly better for the HBO group (2%) than for the non-HBO group (36%) (p < 0.05). Conclusions: The present study showed a potential value of prophylactic HBO for Radiation-induced WMIs, which justifies further evaluation to confirm its definite benefit

AIM: To evaluate the effectiveness of paracetamol as a prophylactic analgesic for hysterosalpingography (HSG). DESIGN: A prospective double blind randomized controlled trial comparing one 1 g of paracetamol (SmithKline Beecham, Brentford, U.K.) to placebo taken 30 min before HSG. One hundred consecutive out-patients were studied prospectively. The analgesic effectiveness during the procedure and at 24 h and 1 week post procedure was analysed by a postal pain score questionnaire. Additional data on the ethnicity of the patient, sex and level of experience of the radiologist performing the hysterosalpingogram, the parity of the patient, the ease of the procedure, and whether pathology was identified were also recorded. RESULTS: Eighty-eight patients (88%) replied, 39 (44%) received paracetamol and 49 placebo (56%). During the procedure 3/39 (7%) of women in the paracetamol group were pain-free compared to 9/49 (18%) in the placebo group, which was not significant (P = 0.11). At 24 h, 15/39 (38%) of women in the paracetamol group were pain-free compared to 20/49 (41%) in the placebo group, which was not significant (P = 0.82). At 1 week, 27/39 (69%) of women in the paracetamol group were pain-free compared to 29/49 (59%) in the placebo group, which was not significant (P = 0.33). No significant difference in mean pain scores was determined during the procedure (P 0.91), or at 24 h post procedure (P = 0.94). Similarly, no difference in mean pain scores was identified with regard to the ethnicity of the patient, the sex of the radiologist performing the procedure, the level of experience of the radiologist performing the procedure, or whether pathology was present or not. Difficult cannulations were associated with higher mean pain scores, however, there was no difference in mean pain scores between the paracetamol or placebo groups for both easy and difficult cannulations. CONCLUSION: Paracetamol is not effective as a prophylactic analgesic for HSG. If a prophylactic

Infections represent a leading cause of mortality in patients with acute ischemic stroke, but it is unclear whether prophylactic antibiotic treatment improves the outcome. We aimed to evaluate the effects of this treatment on infection incidence and short-term mortality. This was a pragmatic, prospective multicenter real-world analysis of previously independent consecutive patients with acute ischemic stroke who were >18 years, and who had at admission National Institutes of Health Stroke Scale (NIHSS) >11. Patients with infection at admission or during the preceding month, with axillary temperature at admission >37 °C, with chronic inflammatory diseases or under treatment with corticosteroids were excluded from the study. Among 110 patients (44.5 % males, 80.2 ± 6.8 years), 31 (28.2 %) received prophylactic antibiotic treatment, mostly cefuroxime (n = 21). Prophylactic antibiotic treatment was administered to 51.4 % of patients who developed infection, and to 16.4 % of patients who did not (p antibiotic treatment (RR 5.84, 95 % CI 2.03-16.79, p antibiotic treatment did not differ between patients who died during hospitalization and those discharged, or between patients who died during hospitalization or during follow-up and those who were alive 3 months after discharge. Prophylactic administration of antibiotics in patients with severe acute ischemic stroke is associated with an increased risk of infection during hospitalization, and does not affect short-term mortality risk.

Although topical agents for the treatment of tinea capitis decrease viable fungal elements and reduce shedding, their use as a prophylactic agent has not been investigated. This study evaluated the effectiveness of a prophylactic ketoconazole shampoo (Nizoral 2%) protocol to reduce the number of clinically evident tinea capitis infections in a high-risk African American, urban population. We conducted a retrospective analysis of a ketoconazole prophylaxis protocol that was implemented at an urban pediatric clinic for medically fragile children. Patients at high risk for tinea capitis received twice-weekly ketoconazole shampoo. The primary outcome of the study was a reduction in the number of documented tinea capitis infections between the 12-month preprotocol and 12-month postprotocol periods. A secondary outcome included the evaluation of predisposing risk factors for acquiring tinea infections. Ninety-seven patients, with a mean age of 8.06 years, were included. Most patients (78%) were African American. There were a total of 13 tinea capitis infections during the 12-month preprotocol period. During the 12-month postprotocol period, 41 infections were documented: 37 (90.2%) in the prophylaxis group and 4 (9.8%) in the nonprophylaxis group. The average numbers of per-patient infections in the postprotocol period were 0.79 and 0.08 in the prophylaxis and nonprophylaxis groups, respectively. Initiation of prophylaxis did not reduce tinea capitis infections (p=NS). Previous history of infection and a high level of care were significant predictors of infections (pshampoo) prophylaxis protocol.

To characterize the short- and long-term outcome (>12 months), complications, and owner satisfaction following prophylactic laparoscopic-assisted gastropexy (LAG) in dogs. Retrospective study. Client-owned dogs (n = 49). Dogs that underwent prophylactic LAG at 2 veterinary academic hospitals were studied. Surgical time, anesthesia time, concurrent intra- and extra-abdominal procedures, and intraoperative and postoperative complications were recorded following review of medical records. Veterinarian and/or owner follow-up was obtained to determine outcome and satisfaction with LAG. Five of 49 dogs (10%) experienced complications related to abdominal access during LAG. Four percent (2/49) of dogs experienced an intraoperative complication. Follow-up information was available for 89% of dogs (44/49). Four dogs died of causes unrelated to LAG or gastric dilatation volvulus (GDV) in the follow-up period. Two dogs experienced major postoperative complications requiring additional veterinary intervention. Thirty percent (13 dogs) experienced a minor postoperative self-limiting wound-related complication. Median follow-up time was 698 days (range, 411-1825). No dogs experienced GDV. One hundred percent of dog owners were satisfied with LAG, would repeat the procedure in a future pet, and would recommend the procedure to a friend or family member. LAG was an effective procedure for prevention of GDV and was associated with high client satisfaction in this cohort of dogs. A moderate rate of postoperative wound complications occurred that were minor and self-limiting in nature. © Copyright 2016 by The American College of Veterinary Surgeons.

Full Text Available Background/Aim. It has been observed that a large number of patients with low urinary tract symptoms due to benign prostatic hyperplasia (LUTS/BPH has been treated with a combination of tamsulosin (TAM + Serenoa repens (SR (TAM + SR. The aim of this study was to compare a combination TAM + SR with TAM and SR alone, to see if there was any difference in efficacy and tolerance of each in patients with LUTS/BPH. Methods. In this prospective study patients had to have prostate volume (PV 3, a maximal flow rate (Qmax of 5-15 mL/s, with post voiding residual volume (PVR < 150 mL and serum prostatic antigen (PSA < 4 ng/mL. TAM (0.4 mg was administered once a day, SR (320 mg daily or SR (320 mg + TAM (0.4 mg daily for a median period of 6 months. Results. A total of 297 patients were recruited, whereas 265 patients were fully available: 87 into the group TAM, 97 into the group SR and 81 into the group TAM + SR. There was no statistically significant difference between the treatment groups in the sense of demographic and other baseline parameters. No difference was found among the 3 treatment groups, neither in the major endpoint of the study in the sense of a change between baseline and final evaluation in total IPSS, obstructive and irritative subscores, improvement of QoLs, increase in Qmax, nor for the second endpoint including diminution of PV, PSA and PVR. During the treatment period 20 (23% of the patients managed with TAM and 17 (21% with TAM + SR had drug-treated with related adverse reactions. No adverse effect was detected in the group SR. Conclusion. Treatment of BPH by both SR and TAM seems to be efficacious alone. None of them had superiority over another and, additionally, a combined therapy (TAM + SR does not provide extra benefits. Furthermore, SR is a well-tolerated agent that can be used alternatively in the treatment of LUTS/BPH.

There are no guidelines for antimicrobial use in experimental animals even though appropriate selection is required to reduce risk of surgical site infection (SSI) and resistance development. Pigs are used extensively as experimental surgical models for people. This review compares reported antimicrobial prescription in recently published pig surgical studies (retrieved by PubMed, Web of Knowledge and Google Scholar) with human guidelines for prophylactic antimicrobial use (National Institute of Clinical Excellence and the American Society of Health-System Pharmacists). A five-point appropriate antimicrobial use index (AAUI), based on aforementioned guidelines, was used to grade 233 studies. Use of World Health Organization-designated critically important antimicrobials (CIA) was recorded. Antimicrobial use was described in 111 of 233 (48 per cent) papers. AAUI scores of 5 (maximal compliance) and 0 (no compliance) were awarded to 34 (15 per cent) and 101 (43 per cent) articles. Where reported, prophylactic antimicrobials were mostly administered after surgery (62/95, 65 per cent) and intramuscularly (36/72, 50 per cent). CIAs were described in 21 of 111 (19 per cent) papers and SSIs in 21 of 233 (9 per cent). Reported antimicrobial prophylaxis in experimental pig surgery deviates from human clinical guidelines. This has implications for antimicrobial resistance, study quality and animal welfare. Until species-specific guidelines are formulated, experimental surgical studies involving animals would probably benefit from adherence to human guidelines. British Veterinary Association.

Inadequate anti-factor Xa levels and increased venous thromboembolic events occur in trauma patients receiving standard prophylactic enoxaparin dosing. The aim of this study was to test the hypothesis that higher dosing (40 mg twice daily) would improve peak anti-Xa levels and decrease venous thromboembolism. A retrospective review was performed of trauma patients who received prophylactic enoxaparin and peak anti-Xa levels over 27 months. Patients were divided on the basis of dose: group A received 30 mg twice daily, and group B received 40 mg twice daily. Demographics and rates of venous thromboembolism were compared between dose groups and patients with inadequate or adequate anti-Xa levels. One hundred twenty-four patients were included, 90 in group A and 34 in group B. Demographics were similar, except that patients in group B had a higher mean body weight. Despite this, only 9% of group B patients had inadequate anti-Xa levels, compared with 33% of those in group A (P = .01). Imaging studies were available in 69 patients and revealed 8 venous thromboembolic events (P = NS, group A vs group B) with significantly more venous thromboembolic events occurring in patients with low anti-Xa levels (P = .02). Although higher dosing of enoxaparin led to improved anti-Xa levels, this did not equate to a statistical decrease in venous thromboembolism. Copyright © 2013 Elsevier Inc. All rights reserved.

Can serological methods help distinguish between prophylactic and alloimmune anti-D?

Enzyme indirect antiglobulin test (EIAT) and polyethylene glycol IAT (PIAT) were evaluated for their potential use as tests to distinguish between prophylactic and alloimmune anti-D in plasma by comparing with a tube variation of the standard low ionic strength solution-IAT (LISS-IAT). Laboratories performing the screening of RhD-negative pregnant women are required to provide clinicians with guidance as to the source of detected RhD antibodies. Currently, this is derived from RhIg immunoprophylaxis history, agglutination scores and titration results, where performed. A serological test that can differentiate between prophylactic and alloimmune anti-D would be useful in the diagnosis of RhD alloimmunisation in pregnant women. Plasma samples (n = 273) [fresh (collected from April 2014 to February 2015) and frozen (up to 2 years)] from antenatal females, preoperative males and females over child-bearing age were used in this study. Samples were identified as containing anti-D by routine column agglutination (CAT) and were tested by tube LISS-IAT, EIAT and PIAT, and a score difference was calculated. A total of 32% of alloimmune anti-D samples demonstrated an increase in agglutination score (+2 or +3) when tested by EIAT. A significant increase in agglutination score for alloimmune samples using EIAT compared with LISS-IAT was observed. EIAT had a sensitivity (Sn) of 59%, positive predictive value (PPV) of 100% and specificity (Sp) of 100% for alloimmune anti-D. EIAT is capable of confirming but not excluding the presence of alloimmune anti-D in samples where anti-D is detected in routine antibody screening. © 2017 British Blood Transfusion Society.

Posterior epistaxis is a frequent emergency, and the key to efficient management is identification of the bleeding point. We performed a retrospective study of 318 patients with posterior epistaxis treated with endoscopic bipolar electrocautery during a 4-year period. Distribution of the bleeding sites was recorded. Patients with no definite bleeding sites in the first operation were assigned to Group A (n = 39) and Group B (n = 34). Patients in Group A were only observed in the ward. Patients in Group B were given prophylactic electrocoagulation at the common bleeding points. Of the 318 patients, bleeding sites were successfully identified and coagulated in 263 patients. All of them were located posteriorly, with 166 on the lateral nasal wall, 86 on the septum, and 11 on the anterior face of the sphenoid sinus. The rebleeding rate of Group B (8.8%) was lower than that of Group A (38.5%) (p < 0.01).

The aim of this study was to analyze the cases of gynecomastia associated with α1A-adrenergic receptor antagonists (α1-ARAs) in the Italian spontaneous reporting system database (Rete Nazionale di Farmacovigilanza or RNF) and in the World Health Organization ICSRs database (VigiBase(™)), focusing on tamsulosin use. We analyzed the spontaneous reports of gynecomastia related to the use of α1-ARAs and collected from the RNF and from VigiBase(™) up to December 2012. Cases of gynecomastia have been defined as reports associated with gynecomastia according with Medical Dictionary for Regulatory Activities (MedDRA). Reporting odds ratio (ROR) and Information Component (IC) were calculated as measures of disproportionality in RNF and VigiBase(™), respectively. Up to December 2012, about 186,000 reports were recorded in the RNF. Among these, 902 reports of adverse drug reaction (ADR) have been associated with the use of at least one α1-ARAs. Of these, in 15 cases, gynecomastia was a listed ADR: in 10, the suspected drug was tamsulosin (in eight, it was the sole suspect); in two, doxazosin and alfuzosin, respectively; and in one, terazosin. ROR for tamsulosin was 5.3 (95% CI 1.8, 15.7). In VigiBase(™), 84 reports of gynecomastia indicated tamsulosin as suspected drug. Tamsulosin-associated gynecomastia showed the highest IC value within this class of drugs (IC 95% 2.43). In this study, we highlight a possible association between gynecomastia and tamsulosin use. To our knowledge, this association has not been described before and could represent a potential signal.

"Ejaculatory disorders and α1-adrenoceptor antagonists therapy: clinical and experimental researches"

Full Text Available Abstract Background It is well known that the use of the α-adrenergic receptor antagonists in the BPH therapy may induce ejaculatory disorder. A review of clinical literature shows a greater incidence of ejaculatory disorder during the use of tamsulosin compared with alfuzosin. Anejaculation has been until now referred to retrograde ejaculation due to relaxation of prostatic and bladder neck smooth muscle tone. In a recent researches was evaluated the effect of tamsulosin and alfuzosin on rat vas deferent "in vitro", concluding that tamsulosin may "cause ejaculatory dysfunction by altering the progression and emission of sperm". An abnormal increase of contraction would be the cause of ejaculatory disorder. The aim of our paper is to compare human and rat vas deferens contractile activity and to evaluate with a clinical study if tamsulosin causes retrograde ejaculation disorder. Methods We have revaluated the human and rat vas deferens contractile activity in vitro according to our experience and literature. We have also performed a clinical study on 10 patients (48–72 y affected by anejaculation. Post-coital urine was examined to search spermatozoa. Results Human and rat vas deferens activity is not comparable. Contractile activity induced by norepinephrin after tamsulosin incubation in rat prostatic vas deferens strips is similar to the contractile activity evoked by norepinephrin in human strips. Spermatozoa were found in post coital urine of 6 patients. Conclusion In our opinion the treatment with tamsulosin may induce retrograde ejaculation but not other ejaculatory disorder due to abnormal sperm progression.

Objective: To discuss the effect and safety of transcatheter angiographic embolization (TAE)for managing massive obstetric haemorrhage. Methods: 17 cases of obstetric massive haemorrhage or with haemorrhage tendency were treated with TAE. Among them 14 cases had haemorrhage already, including 10 cases after abortion, caesarean section or normal labor and other 4 of hydatidiform mole. 3 cases with obstetric haemorrhage tendency included 2 cases of placenta praevia and 1 case of cervical pregnancy. Selective catheterization into bilateral uterine arteries or internal iliac arteries for DSA, showed the cause and location of the haemorrhage and then embolized with gelfoam sponge chips (1-3 mm) or Polyvinyl Alcohol(PVA); and part of the cases with MTX through uterine arterial perfusion. Results: The successful rate of catheterization was 100%. The achievement in 14 cases showed no active haemorrhage immediately after the procedure and no vaginal bleeding after 1-5 days. In 3 prophylactic cases before abortion or uterine curettage, obstetric massive haemorrhage occurred in 1 case, but not so in other 2 cases. Conclusions: TAE is an effective treatment for obstetric massive haemorrhage, with the advantages of minimal trauma, fast and definite treating effect and less complications. Prophylactical application for high risk patients can reduce the bleeding and mortality. (authors)

Material and methods: This prospective randomized, parallel, single-blind clinical trial was developed in the Dental Clinic of the Universidad Alas Peruanas in Trujillo (Peru. The patients, who required simple extraction due to dental caries, were randomly distributed into three groups: 30 of them took 550mg naproxen sodium in the preoperative period and then every 12 hours, other 30 took 550mg naproxen sodium in the postoperative period and then every 12 hours, and 30(control group, received 400mg ibuprofen in the postoperative period and then every 8 hours, depending on the established criteria. The procedure was standardized, analgesic effectiveness was assessed by visual analog scale and the presence of adverse drug reactions was evaluated as well. Data were analyzed using ANOVA and Duncan’s test using IBM SPSS 22 with a significance level of 5%. Results: Continued therapy with naproxen sodium showed greater analgesic effectiveness after a simple extraction at 1, 8 and 24 hours (p<0.005. Conclusion: Continued therapy with naproxen sodium presented greater effectiveness than prophylactic therapy with naproxen sodium after a simple extraction.

Prophylactic radiotherapy of the breast in patients with prostatic carcinoma before application of contrasexual hormones

Symptoms and objective parameters of gynecomastia are analysed in 113 patients, who received prophylactic irradiation of the breast (12 Gy in 3 fractions) prior to estrogen therapy of prostatic carcinoma. Another 10 patients were treated equally after estrogens had caused severe complaints. Symptoms increased from 10% to 100% in relation to 4 classes of gynecomastia. They were mild in 27.5%, moderate in 23.9% and severe in 8.8%. A correlation between metric classification and graded symptoms became more evident when only 2 groups were distinguished. With a maximum diameter of 3.5 cm only 17% of the patients had mostly slight discomfort in contrast to 70% of the patients with a gland of more than 3.5 cm in diameter; they revealed moderate or serious complaints. These results indicate that prophylactic radiotherapy may reduce severe complications to less than 10% as compared to 70-80% without irradiation. If gynecomastia has developed, regression by subsequent radiotherapy seems to be impossible; but the intensity of complaints could be reduced in our ten patients. Provided that irradiation precedes estrogen application, this sequence may be considered as a reasonable alternative to expensive antiandrogen therapy.

Background and purpose: Concomitant radio-chemotherapy is the gold standard treatment for unresectable head and neck carcinomas. Placement of prophylactic gastrostomy has been proposed to provide adequate nutrition during the therapeutic sequence. The objectives of this study were to assess the impact of prophylactic gastrostomy on the 6-month quality of life, and to determine the factors related to this quality of life. Materials and methods: Design. randomized, controlled, open study ('systematic percutaneous gastrostomy' versus 'no systematic gastrostomy'). Patients. squamous cell head and neck carcinoma (stages III and IV, UICC 1997). Setting. oncological departments of French university teaching hospitals. Treatment. optimal concomitant radio-chemotherapy. Evaluations. T0 baseline evaluation, T1 during the treatment, T2 end of the treatment, and T3 6-month post-inclusion. Primary endpoint. 6-month quality of life (Qol) assessed using SF36, EORTC QLQ-C30, EORTC QLQ H and N35 questionnaires. Results: The Qol changes from baseline included a decline (T1 and T2) followed by an improvement (T3). Qol at 6 months was significantly higher in the group receiving systematic prophylactic gastrostomy (p = 10 -3 ). Higher initial BMI and lower initial Karnofsky index were significant factors related to a higher 6-month Qol. Conclusions: The study results suggest that prophylactic gastrostomy improves post-treatment quality of life for unresectable head and neck cancer patients, after adjusting for other potential predictive quality of life factors.

Abstract The aim of this study was to investigate whether younger age at surgery is associated with the increased incidence of postoperative complications after prophylactic thyroidectomy in pediatric patients with multiple endocrine neoplasia (MEN) 2. The shift toward earlier thyroidectomy has resulted in significantly less medullary thyroid carcinoma (MTC)-related morbidity and mortality. However, very young pediatric patients might have a higher morbidity rate compared with older patients. Hardly any literature exists on complications in the very young. A retrospective single-center analysis was performed on the outcomes of MEN2 patients undergoing a prophylactic total thyroidectomy at the age of 17 or younger. Forty-one MEN2A and 3 MEN2B patients with thyroidectomy after January 1993 and at least 6 months of follow-up were included, subdivided in 9 patients younger than 3 years, 15 patients 3 to 6 years, and 20 patients older than 6 years. Postoperative hypocalcemia and other complications were registered. Twelve (27%) patients developed transient hypocalcemia and 9 (20%) patients suffered from permanent hypocalcemia, with a nonsignificant trend toward higher incidence with decreasing age. Three (7%) patients had other complications, of whom 2 were younger than 3 years. For patients younger than 3 years, the average length of stay (LOS) was 6.7 days, versus 1.7 and 3.5 days, respectively, for the older patient groups (P < 0.05). Patients with complications had a longer LOS compared with patients without (5.0 vs 2.0, P < 0.01). None of the patients had clinical signs of recurrent MTC after a mean follow-up of 10.5 years. Prophylactic thyroidectomy in very young children is associated with a higher rate of complications, causing a significant increased LOS. Irrespective age of surgery, MTC did not recur in any patient. In planning optimal timing of surgery, clinicians should take the risk of complications into account. We advise not to perform total

Full Text Available Background: Fluoridated prophylactic agents have been reported to cause corrosion and discoloration of titanium alloys. Degradation in the mechanical properties lead to a decrease in a suitable orthodontic force, thereby causing delayed leveling of crooked teeth. This study was designed to evaluate the load deflection characteristics of thermal nickel titanium arch wires during unloading phase after ninety minutes immersion in three different fluoride agents. Material and methods: Forty specimens of thermal wires were obtained from Ortho Technology Company, which had 0.019” × 0.025” rectangular in cross section. Ten specimens from the wire size were immersed in one of the tested fluoride prophylactic agents (neutral sodium fluoride gel, stannous fluoride gel or Phos-Flur® mouth rinse or in the controlled medium of normal saline and incubated at 37°C for ninety minutes. A Wp 300 universal material testing machine was modified and used to perform a three-point bending test in a water path at 37 ± 1°C. The statistical difference between the different agents was analyzed using ANOVA and least significant difference tests. Results: The unloading forces at 0.5 mm, 1.0 mm, and 1.5 mm where significantly reduced especially in acidulated phosphate fluoride treated specimens followed by neutral fluoride treated specimens. Conclusion: Based on the results found in this study it can be preferred to use fluoride prophylactic agents with the least acidity and fluoride ions concentration.

In the year 2005, Chang and Cambell described unusual reaction of the iris during the cataract surgery in patients treated with tamsulosine. This was named as IFIS, an acronym for the Intraoperative Floppy Iris Syndrome. In its advanced stage, the syndrome is characterized by insufficient mydfiasis before the surgery, narrowing of the pupil during the surgery, its impossible dilatation during the surgery by means of stretching, unusual elasticity of the pupilar margin, surging and fluttering iris with tendency to prolapse. The same manifestations we observed in our patients and we confirm the direct connection with tamsulosine hydrochloride treatment. Tamsulosine is the antagonist of alpha 1A adrenergic receptors whose are present, except in the smooth musculature of the prostate gland and the urinary bladder, in the iris dilator as well. At the same time we observed this syndrome rarely in some patients not using tamsulosine. In most cases, these patients were treated with antipsychotic drugs.

Full Text Available Purpose: The purpose of this study was to evaluate the incidence, risk factors, and impact of intraoperative floppy iris syndrome (IFIS on surgical performance. Materials and Methods : Consecutive cataract surgeries from October 2010 to Feb 2011 (1003 eyes, 980 patients; 568 males, 412 females were analyzed prospectively. Operating surgeon, masked about medication history, noted the intraoperative details. Cases were identified as IFIS or non-IFIS. Multivariate analysis was performed to find risk factors for IFIS. Results : Prevalence of tamsulosin use among men undergoing cataract surgery was 7.0% (41 with incidence of IFIS 4.78% (48. On multivariate analysis, hypertension (OR: 3.2, 95% confidence interval, 95% CI: 1.39-6.57; P = 0.005, use of tamsulosin (OR: 133.32, 95% CI: 50.43-352.48; P < 0.0001, or alfuzosin (OR: 9.36, 95% CI: 2.34-37.50; P = 0.002 were the factors associated with IFIS. Among men taking tamsulosin (n = 41 and alfuzosin (n = 28, 68.3% and 16.6% developed IFIS, respectively. In subgroup analysis of men on tamsulosin, no factor added to the risk posed by tamsulosin. Seventeen of 944 eyes not exposed to any drug had IFIS (0.018%. On subgroup analysis, only risk factor for IFIS was hypertension (OR: 4.67, 95% CI: 1.63-13.35; P = 0.002. Of 48 IFIS eyes, the surgeon observed increased difficulty in 57.1% (21 and additional measures were required in 9 eyes. Mean operative time was increased in IFIS eyes (11.68 ± 3.46 vs. 10.01 ± 0.22 min; P = 0.001. Surgical outcome was good in all cases. Conclusion : The prevalence of tamsulosin intake and IFIS incidence is higher in India. Current tamsulosin/alfuzosin use and hypertension are important risk factors. IFIS makes the surgery more difficult, significantly prolongs the operative time, and predisposes for other intraoperative complications. However, with appropriate management, final operative outcome is not affected.

The aim of the study was to work out a prophylactic program for strain urinary incontinence. Analysis of literature on the subject and results of own investigations presented in the first part of the paper indicate that the program of prophylaxis of strain urinary incontinence should primarily include: (1) Preparation of the medical staff (nurses, midwives) for propagating health education among women on prevention of strain urinary incontinence. (2) Preparation of adequate educational materials in the form of brochures, leaflets, information posters about symptoms, causes and prophylaxis of urinary incontinence indicating health care institutions available to all women when the disease is suspected or already present. (3) Propagation of problems connected with strain urinary incontinence in the mass media providing information to a wide audience in order to make people realize the significance of this social problem and break stereotypes associated with this disease of "shame". (4) Preparation of sets of exercises for the muscles of the base of the pelvis to be performed during pregnancy, confinement and menopause to maintain their proper function. (5) Indicating factors predisposing to strain urinary incontinence with focus on possibilities of their reduction or elimination.

Guidelines regarding the impact and value of prophylaxis or maintenance therapy in equine gastric ulcer syndrome (EGUS) are not well-established or defined. The merits and the magnitude of effects of prophylaxis for spontaneous or recurrent squamous gastric ulceration in horses in training are uncertain. To pool data from randomised controlled trials (RCTs) to eliminate reporting bias and evaluate the efficacy of prophylactic omeprazole in the prevention of EGUS in training horses, and secondarily to compare prophylactic dosages of omeprazole. Meta-analysis. This meta-analysis was conducted according to the recommendations of the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines. A systematic literature search identified RCTs comparing omeprazole prophylaxis with sham in prevention of EGUS. Data were analysed using the Mantel-Haenszel test method to calculate risk ratio (RR) or mean difference (MD) with 95% confidence intervals (CIs). Primary outcome was efficacy of prophylaxis. Secondary outcome was endoscopic severity of ulceration. The influence of study characteristics on the outcomes was examined by subgroup analyses. In preventing gastric ulcer occurrence, omeprazole prophylaxis was superior to sham in training horses (7 trials, 566 horses, RR 0.28, 95% CI 0.18-0.43; 23.4% in omeprazole prophylaxis vs. 77.2% in sham; high quality evidence). Prevalence of ulceration was 75.3 and 87.2% in the sham arms of the 1 mg/kg and 2 mg/kg omeprazole groups, respectively. Severity scores were significantly lower for omeprazole vs. sham (mean difference [MD] -1.05; 95% CI -1.35 to -0.69). Subgroup analyses comparing prophylactic omeprazole dosages resulted in a mean difference of -0.94 and -1.60 for the 1 and 2 mg/kg groups, respectively. Studies showed heterogeneity with regard to prophylactic dose. Omeprazole prophylaxis in active training horses significantly reduces gastric ulceration compared with no prophylaxis (sham) with the

To investigate impact of prophylactic peritoneal dialysis (PD) on clinical outcomes and inflammatory cytokines in children following cardiac surgery with cardiopulmonary bypass. Prospective before-and-after nonrandomized cohort study. Pediatric cardiovascular intensive care unit in tertiary hospital. Fifty-two consecutive neonates and infants at high risk for postoperative fluid overload following cardiopulmonary bypass. All had PD catheters placed during primary cardiac surgery. Initial 27 patients were managed with passive peritoneal drainage and diuretics (controls). Following 25 patients were started on prophylactic PD in immediate postoperative period and managed per PD protocol (+PD). Cumulative fluid balance, indices of disease severity, and clinical outcomes were prospectively collected. Plasma interleukin-6 and interleukin-8 were measured immediately before-and-after cardiopulmonary bypass and at 24 and 48 hours post-cardiopulmonary bypass. Demographics, diagnoses, and intraoperative variables were similar. Median net fluid balance was more negative in +PD at 24 hours, -24 mL/kg (interquartile range: -62, 11) vs. +18 mL/kg (interquartile range: -26, 11), P = .003, and 48 hours, -88 mL/kg (interquartile range: -132, -54) vs. -46 mL/kg (interquartile range: -84, -12), P = .004. +PD had median 55 mL/kg less fluid intake at 24 hours, P = .058. Peritoneal drain, urine, and chest tube output were comparable over first 24 hours. Mean inotrope score was lower in +PD at 24 hours. +PD had earlier sternal closure--24 hours (interquartile range: 20, 40) vs. 63 hours (interquartile range: 44, 72), P interquartile range: 49, 135) vs. 125 hours (interquartile range: 70, 195), P = .10. +PD experienced lower serum concentrations of interleukin-6 and interleukin-8 at 24 hours. Prophylactic PD is associated with greater net negative fluid balance, decreased inotrope requirements, and lower serum concentrations of inflammatory cytokines in the early postoperative

Prophylactic or therapeutic immunomodulation is an antigen-independent strategy that induces nonspecific immune system activation, thereby enhancing host defense to disease. In this study, we investigated the effect of prophylactic immunomodulation on the outcome of influenza virus infection using three bacterially derived immune-enhancing agents known for promoting distinct immunological profiles. BALB/c mice were treated nasally with either cholera toxin (CT), a mutant form of the CT-related Escherichia coli heat-labile enterotoxin designated LT(R192G), or CpG oligodeoxynucleotide. Mice were subsequently challenged with a lethal dose of influenza A/PR/8/34 virus 24 h after the last immunomodulation treatment and either monitored for survival or sacrificed postchallenge for viral and immunological analysis. Treatment with the three immunomodulators prevented or delayed mortality and weight loss, but only CT and LT(R192G) significantly reduced initial lung viral loads as measured by plaque assay. Analysis performed 4 days postinfection indicated that prophylactic treatments with CT, LT(R192G), or CpG resulted in significantly increased numbers of CD4 T cells, B cells, and dendritic cells and altered costimulatory marker expression in the airways of infected mice, coinciding with reduced expression of pulmonary chemokines and the appearance of inducible bronchus-associated lymphoid tissue-like structures in the lungs. Collectively, these results suggest that, despite different immunomodulatory mechanisms, CT, LT(R192G), and CpG induce an initial inflammatory process and enhance the immune response to primary influenza virus challenge while preventing potentially damaging chemokine expression. These studies provide insight into the immunological parameters and immune modulation strategies that have the potential to enhance the nonspecific host response to influenza virus infection.

To compare 2 different femoral neck augmentation techniques at improving the mechanical strength of the femoral neck. Twenty pairs of human cadaveric femora were randomly divided into 2 groups. In 1 group, the femora were augmented with a steel spiral; the other group with the cemented technique. The untreated contralateral side served as an intraindividual control. Fracture strength was evaluated using an established biomechanical testing scenario mimicking a fall on the greater trochanter (Hayes fall). The peak load to failure was significantly higher in the steel spiral group (P = 0.0024) and in the cemented group (P = 0.001) compared with the intraindividual controls. The peak load to failure showed a median of 3167 N (1825-5230 N) in the spiral group and 2485 N (1066-4395 N) in the spiral control group. The peak load to failure in the cemented group was 3698 N (SD ± 1249 N) compared with 2763 N (SD ± 1335 N) in the cement control group. Furthermore, fracture displacement was clearly reduced in the steel spiral group. Femoral augmentations using steel spirals or cement-based femoroplasty are technically feasible procedures. Our results demonstrate that a prophylactic reinforced proximal femur has higher strength when compared with the untreated contralateral limb. Prophylactic augmentation has potential to become an auxiliary treatment option to protect the osteoporotic proximal femur against fracture.

Full Text Available BACKGROUND AND OBJECTIVES: Postoperative bleeding has a great clinical importance and can contribute to increased mortality and morbidity in patients undergoing coronary artery bypass graft surgery. In this prospective, randomized, double-blind study, we evaluated the effect of prophylactic administration of fibrinogen concentrate on post-coronary artery bypass graft surgery bleeding. METHODS: A total of 60 patients undergoing coronary artery bypass surgery were randomly divided into two groups. Patients in the fibrinogen group received 1 g of fibrinogen concentrate 30 min prior to the operation, while patients in the control group received placebo. Post-operative bleeding volumes, prothrombin time, partial thromboplastin time, INR, hemoglobin and transfused blood products in both groups were recorded. A strict red blood cell transfusion protocol was used in all patients. RESULTS: There were no significant differences between intra-operative packed red blood cells infusion in the studied groups (1.0 ± 1.4 in fibrinogen group, and 1.3 ± 1.1 in control group. Less postoperative bleeding was observed in the fibrinogen group (477 ± 143 versus 703 ± 179, p = 0.0001. Fifteen patients in the fibrinogen group and 21 in the control group required post-op packed red blood cells infusion (p = 0.094. No thrombotic event was observed through 72 h after surgery. CONCLUSION: Prophylactic fibrinogen reduces post-operative bleeding in patients undergoing coronary artery bypass graft.

To evaluate treatment patterns and clinical factors affecting gout flare in South Korea. We retrospectively examined data from 401 patients seen at nine rheumatology multicenter clinics, under urate lowering therapy (ULT) more than 6 months after stopping prophylactic medication. Demographic data, clinical and laboratory features were collected at the initiation of ULT, upon stopping prophylaxis, and 6 months after. The mean age was 52.2 years and mean disease duration was 25.0 months. The male-to-female count was 387 : 14. The most common ULT starting agent was allopurinol 83.8%. Colchicine (62.3%) was the most commonly prescribed prophylactic agent. During ULT, 134 of the 401 patients (33.4%) experienced at least one gouty attack in the period from stopping prophylaxis to 6 months later. The duration of prophylaxis was different between those with serum uric acid levels below 6 mg/dL and those over 6 mg/dL (P = 0.001). Of the 179 patients (44.6%) who attained target serum uric acid (SUA) levels (6 mg/dL) at the end of prophylaxis, those taking gout flares during ULT. © 2014 Asia Pacific League of Associations for Rheumatology and Wiley Publishing Asia Pty Ltd.

Parastomal hernia is a very common complication after colostomy, especially end-colostomy. It is unclear whether prophylactic placement of mesh at the time of stoma formation could prevent parastomal hernia formation after surgery for rectal cancer. A systematic review and meta-analysis were conducted to evaluate the efficacy of prophylactic mesh in end-colostomy construction. PubMed, Embase, and the Cochrane Library were searched, covering records entered from their inception to September 2015. Randomized controlled trials (RCTs) comparing stoma with mesh to stoma without mesh after surgery for rectal cancer were included. The primary outcome was the incidence of parastomal hernia. Pooled risk ratios (RR) with 95 % confidence intervals (CI) were obtained using random effects models. Six RCTs containing 309 patients were included. Parastomal hernia occurred in 24.4 % (38 of 156) of patients with mesh and 50.3 % (77 of 153) of patients without mesh. Meta-analysis showed a lower incidence of parastomal hernia (RR, 0.42; 95 % CI 0.22-0.82) and reoperation related to parastomal hernia (RR, 0.23; 95 % CI 0.06-0.89) in patients with mesh. Stoma-related morbidity was similar between mesh group and non-mesh group (RR, 0.65; 95 % CI 0.33-1.30). Prophylactic placement of a mesh at the time of a stoma formation seems to be associated with a significant reduction in the incidence of parastomal hernia and reoperation related to parastomal hernia after surgery for rectal cancer, but not the rate of stoma-related morbidity. However, the results should be interpreted with caution because of the heterogeneity among the studies.

The incidence of supraclavicular metastasis as the initial failure and the failure patterns in patients with four or more positive axillary lymph nodes (PALNs) after breast-conserving therapy (BCT) without prophylactic supraclavicular irradiation were investigated. Between 1991 and 2002, a total of 48 women with four or more PALNs underwent BCT without prophylactic supraclavicular irradiation (33 patients with 4-9 PALNs; 15 patients with ≥10 PALNs). The median follow-up time was 50 months. Among the patients with 4-9 PALNs, 3% had isolated supraclavicular metastasis as the initial failure, and 30% had distant metastasis as the initial failure. Among patients with ≥10 PALNs, 7% had isolated supraclavicular metastasis as the initial failure, and 40% had distant metastasis as the initial failure. The 4-year isolated supraclavicular failure rates were 5% for all patients, 3% for patients with 4-9 PALNs, and 8% for patients with ≥10 PALNs. In patients who had undergone BCT and had had four or more PALNs, the major failure pattern was distant failure with or without locoregional failure; isolated supraclavicular failure as the initial failure comprised a less common failure pattern. Omission of prophylactic supraclavicular irradiation may be acceptable for this subset of patients. (author)

Contralateral prophylactic mastectomy: current perspectives

Yao, Katharine; Sisco, Mark; Bedrosian, Isabelle

2016-01-01

There has been an increasing trend in the use of contralateral prophylactic mastectomy (CPM) in the United States among women diagnosed with unilateral breast cancer, particularly young women. Approximately one-third of women CPM in the US. Most studies have shown that the CPM trend is mainly patient-driven, which reflects a changing environment for newly diagnosed breast cancer patients. The most common reason that women choose CPM is based on misperceptions about CPM’s effect on survival and overestimation of their contralateral breast cancer (CBC) risk. No prospective studies have shown survival benefit to CPM, and the CBC rate for most women is low at 10 years. Fear of recurrence is also a big driver of CPM decisions. Nonetheless, studies have shown that women are mostly satisfied with undergoing CPM, but complications and subsequent surgeries with reconstruction have been associated with dissatisfaction with CPM. Studies on surgeon’s perspectives on CPM are sparse but show that the most common reasons surgeons discuss CPM with patients is because of a suspicious family history or for a patient who is a confirmed BRCA mutation carrier. Studies on the cost–effectiveness of CPM have been conflicting and are highly dependent on patient’s quality of life after CPM. Most recent guidelines for CPM are contradictory. Future areas of research include the development of interventions to better inform patients about CPM, modification of the guidelines to form a more consistent statement, longer term studies on CBC risk and CPM’s effect on survival, and prospective studies that track the psychosocial effects of CPM on body image and sexuality.

Bilateral cataract surgery was undertaken in 9 patients but only one patient (on tamsulosin had features of IFIS in both eyes, while 4 patients (2 on tamsulosin and 2 on other AA showed signs of IFIS in one eye only, and 4 patients did not show IFIS in either eye.Conclusion: Most AA were associated with IFIS, but it tends to present as a spectrum of signs rather than full triad originally described. Tamsulosin was most likely to be associated with IFIS; however, its intake does not necessarily mean that IFIS will occur. For patients on AA, the behavior of the iris intraoperatively in one eye is a poor predictor of the other eye. Surgeons should anticipate the occurrence of IFIS in any patient on AA.Keywords: alpha blocker, alpha antagonist, cataract surgery, intraoperative floppy iris syndrome, tamsulosin.

Lower lid entropion secondary to treatment with alpha-1a receptor antagonist: a case report

2010-03-01

Full Text Available Abstract Introduction The use of alpha-1a receptor antagonists (tamsulosin is widely accepted in the treatment of benign prostatic hypertrophy (BPH. It has previously been implicated as a causative agent in intra-operative floppy iris syndrome due to its effects on the smooth muscle. We report a case of lower lid entropion that may be related to a patient commencing treatment of tamsulosin. Case presentation A 74-year-old Caucasian man was started on alpha 1-a receptor antagonist (Tamsulosin treatment for benign prostatic hypertrophy. Eight days later, he presented to the ophthalmology unit with a right lower lid entropion which was successfully treated surgically with a Weiss procedure. Conclusion We report a case of lower lid entropion that may be secondary to the recent use of an alpha-1a blocker (tamsulosin. This can be explained by considering the effect of autonomic blockade on alpha-1 receptors in the Muller's muscle on a patient that may already have an anatomical predisposition to entropion formation due to a further reduction in muscle tone.

Full Text Available We performed a meta-analysis to compare treatment with a combination of solifenacin plus tamsulosin oral controlled absorption system (TOCAS with placebo or TOCAS monotherapy. The aim of the meta-analysis was to clarify the efficacy and safety of the combination treatments method for lower urinary tract symptoms (LUTS. We searched for trials of men with LUTS that were randomized to combination treatment compared with TOCAS monotherapy or placebo. We pooled data from three placebo-controlled trials meeting inclusion criteria. Primary outcomes of interest included changes in International Prostate Symptom Score (IPSS and urinary frequency. We also assessed postvoid residual, maximum urinary flow rate, incidence of urinary retention (UR, adverse events. Data were pooled using random or fixed effect models for continuous outcomes and the Mantel-Haenszel method to generate risk ratio. Reductions in IPSS storage subscore and total urgency and frequency score (TUFS were observed with solifenacin 6 mg plus TOCAS compared with placebo (P< 0.0001 and P< 0.0001, respectively. Reductions in IPSS storage subscore and TUFS were observed with solifenacin 9 mg plus TOCAS compared with placebo (P = 0.003 and P= 0.0006, respectively. Reductions in TUFS was observed with solifenacin 6 mg plus TOCAS compared with TOCAS (P = 0.01. Both combination treatments were well tolerated, with low incidence of UR. Solifenacin 6 mg plus TOCAS significantly improved total IPSS, storage and voiding symptoms compared with placebo. Solifenacin 6 mg plus TOCAS also improved storage symptoms compared with TOCAS alone. There was no additional benefit of solifenacin 9 mg compared with 6 mg when used in combination with TOCAS.

The goal was to examine bacterial antimicrobial resistance of recurrent urinary tract infections in children receiving antibiotic prophylaxis because of primary vesicoureteral reflux. We reviewed data retrospectively for children with documented vesicoureteral reflux in 2 hospitals during a 5-year follow-up period. The patients were receiving co-trimoxazole, cephalexin, or cefaclor prophylaxis or prophylaxis with a sequence of different antibiotics (alternative monotherapy). Demographic data, degree of vesicoureteral reflux, prophylactic antibiotics prescribed, and antibiotic sensitivity results of first urinary tract infections and breakthrough urinary tract infections were recorded. Three hundred twenty-four patients underwent antibiotic prophylaxis (109 with co-trimoxazole, 100 with cephalexin, 44 with cefaclor, and 71 with alternative monotherapy) in one hospital and 96 children underwent co-trimoxazole prophylaxis in the other hospital. Breakthrough urinary tract infections occurred in patients from both hospitals (20.4% and 25%, respectively). Escherichia coli infection was significantly less common in children receiving antibiotic prophylaxis, compared with their initial episodes of urinary tract infection, at both hospitals. Children receiving cephalosporin prophylaxis were more likely to have an extended-spectrum beta-lactamase-producing organism for breakthrough urinary tract infections, compared with children with co-trimoxazole prophylaxis. Antimicrobial susceptibilities to almost all antibiotics decreased with cephalosporin prophylaxis when recurrent urinary tract infections developed. The extent of decreased susceptibilities was also severe for prophylaxis with a sequence of different antibiotics. However, antimicrobial susceptibilities decreased minimally in co-trimoxazole prophylaxis groups. Children receiving cephalosporin prophylaxis are more likely to have extended-spectrum beta-lactamase-producing bacteria or multidrug-resistant uropathogens

Prophylactic continuous positive airway pressure (CPAP) can prevent pulmonary adverse events following upper abdominal surgeries. The present meta-regression evaluates and quantifies the effect of degree/duration of (CPAP) on the incidence of postoperative pulmonary events. Medical databases were searched for randomized controlled trials involving adult patients, comparing the outcome in those receiving prophylactic postoperative CPAP versus no CPAP, undergoing high-risk abdominal surgeries. Our meta-analysis evaluated the relationship between the postoperative pulmonary complications and the use of CPAP. Furthermore, meta-regression was used to quantify the effect of cumulative duration and degree of CPAP on the measured outcomes. Seventy-three potentially relevant studies were identified, of which 11 had appropriate data, allowing us to compare a total of 362 and 363 patients in CPAP and control groups, respectively. Qualitatively, Odds ratio for CPAP showed protective effect for pneumonia [0.39 (0.19-0.78)], atelectasis [0.51 (0.32-0.80)] and pulmonary complications [0.37 (0.24-0.56)] with zero heterogeneity. For prevention of pulmonary complications, odds ratio was better for continuous than intermittent CPAP. Meta-regression demonstrated a positive correlation between the degree of CPAP and the incidence of pneumonia with a regression coefficient of +0.61 (95 % CI 0.02-1.21, P = 0.048, τ (2) = 0.078, r (2) = 7.87 %). Overall, adverse effects were similar with or without the use of CPAP. Prophylactic postoperative use of continuous CPAP significantly reduces the incidence of postoperative pneumonia, atelectasis and pulmonary complications in patients undergoing high-risk abdominal surgeries. Quantitatively, increasing the CPAP levels does not necessarily enhance the protective effect against pneumonia. Instead, protective effect diminishes with increasing degree of CPAP.

Central nervous system (CNS) prophylaxis is required during initial treatment of non-Hodgkin lymphoma (NHL) subtypes that carry a high risk of CNS involvement. Intrathecal (IT) liposomal cytarabine, a formulation with prolonged half-life, has been shown to be safe and effective in the treatment of meningeal disease in patients with high-grade lymphoma. We retrospectively reviewed all adult patients with high-grade NHL that received prophylactic therapy with IT liposomal cytarabine and developed neurologic complications in our institution between April 2007 and May 2009. We recorded information on hospital admission, chemotherapy regimens, clinical features, neuroimaging, cerebrospinal fluid, neurophysiology data, and outcome. Neurotoxicity was graded according to the National Cancer Institute Common Toxicity Criteria (NCI-CTC). Four of fourteen patients (28%) developed moderate or severe neurotoxicity (grades 2 and 3 of the NCI-CTC), manifested as conus medullaris/cauda equine syndrome or pseudotumour cerebri-like syndrome, after a median of 3.5 IT courses of liposomal cytarabine. All patients had received corticosteroids to prevent arachnoiditis. Liposomal cytarabine given via the IT route, even with concomitant corticosteroid administration, can result in significant neurotoxicity in some patients. We discuss the potential pathogenesis of these effects and suggest hypothetical therapeutic measures to prevent these complications. Specialists should be aware of these possible complications when administering prophylactic IT liposomal cytarabine in high-grade NHL patients, and additional prospective studies should be conducted to more clearly delineate the frequency and characteristics of these complications.

Pharmacotherapy as prophylactic treatment of post-traumatic stress disorder: a review of the literature.

Science.gov (United States)

Roque, Autumn Pearl

2015-01-01

Post-traumatic stress disorder has a lifetime prevalence of almost 9% in the United States. The diagnosis is associated with increased rates of comorbid substance abuse and increased rates of depression. Providers are taught how to diagnose and treat PTSD, but little discussion is devoted to how to prevent the disorder. Behavioral research in animal studies has provided some evidence for the use of medications in decreasing the fear response and the reconsolidation of memories. A heightened fear response and the re-experience of traumatic memory are key components for diagnosis. The purpose of this literature review is to examine the evidence for pharmacotherapy as prophylactic treatment in acute stress/trauma in order to prevent the development of post-traumatic stress disorder. The body of the review includes discussions on medications, medications as adjunct to script-driven imagery, and special considerations for military, first responders, and women. This article concludes with implications for practice and recommendations for future research. The key words used for the literature search were "prophylactic treatment of PTSD," "pharmacotherapy and trauma," "pharmacological prevention of PTSD," "beta blockers and the prevention of PTSD," "acute stress and prevention of PTSD," "propranolol and PTSD," "secondary prevention of PTSD," and "medications used to prevent PTSD." Findings were categorized by medications and medications as adjunct to script-driven imagery. The literature suggests that hydrocortisone, propranolol, and morphine may decrease symptoms and diagnosis of post-traumatic stress disorder.

Background: The role of prophylactic factor VIII (FVIII) to decrease hemophilic bleeding and arthropathy is well established. The rationale for this strategy is to convert patients with severe hemophilia A to a moderate clinical phenotype by reducing time spent with a FVIII level <1 IU dL(-1).

Efficacy of Prophylactic use of Antibiotics to Avoid Flare up During Root Canal Treatment of Nonvital Teeth: A Randomized Clinical Trial

Science.gov (United States)

2015-01-01

Objectives: Flare-up during root canal treatment of non vital teeth is a common clinical incident. The aim of the present study was to assess the effect of prophylactic use of antibiotics to avoid flare up during root canal treatment of the teeth having asymptomatic necrotic pulp. Materials and Methods: A randomized double blind clinical trial with parallel design was conducted on 100 subjects with asymptomatic non vital teeth. They were randomly divided into two groups. The first group (50 participants) was given two gram amoxicillin one hour before the first visit of root canal treatment; the second group (50 participants) did not receive any treatment (control group). In both groups, root canal treatment was performed in two visits. The flare up was assessed by the pain visual analogue scale and based on the swelling criteria. The data were processed and analyzed using SPSS statistical software 17. A p-value of 0.05 or less was considered statistically significant. Results: A total of 80% of participants in the experimental group had flare up while 12% of participants had flare up in the control group. Prophylactic Amoxicillin had no effect on inter-appointment flare up (p > 0.05). There was no relationship between flare up and patient’s age, gender and tooth type (p > 0.05). Conclusion: Prophylactic use of Amoxicillin in asymptomatic non vital teeth before root canal treatment had no effect on the incidence of flare-up. PMID:25954695

2005-01-01

Purpose: To investigate whether prophylactic cranial irradiation (PCI) has a role in the management of patients with non-small-cell lung cancer (NSCLC) treated with curative intent. Methods and Materials: A search strategy was designed to identify randomized controlled trials (RCTs) comparing PCI with no PCI in NSCLC patients treated with curative intent. The electronic databases MEDLINE, EMBASE, LILACS, and Cancerlit were searched, along with relevant journals, books, and review articles to identify potentially eligible trials. Four RCTs were identified and reviewed. A total of 951 patients were randomized in these RCTs, of whom 833 were evaluable and reported. Forty-two patients with small-cell lung cancer were excluded, leaving 791 patients in total. Because of the small patient numbers and trial heterogeneity, no meta-analysis was attempted. Results: Prophylactic cranial irradiation did significantly reduce the incidence of brain metastases in three trials. No trial reported a survival advantage with PCI over observation. Toxicity data were poorly collected and no quality of life assessments were carried out in any trial. Conclusion: Prophylactic cranial irradiation may reduce the incidence of brain metastases, but there is no evidence of a survival benefit. It was not possible to evaluate whether any radiotherapy regimen is superior, and the effect of PCI on quality of life is not known. There is insufficient evidence to support the use of PCI in clinical practice. Where possible, patients should be offered entry into a clinical trial

A retrospective evaluation of the total quantity of X-ray procedures and the radiation degree in 310 patients with chronic kidney diseases is given. It is ascertained that only account of integral absorbed dose in the organ tissues, comprising the doses of X-ray examinations of other organs during the patient lifetime, can serve as the main condition for developing well-grounded recommendations concerning rational complex of examination methods during prophylactic examination of patients with chronic kidney disease. 9 refs.; 4 figs

Severe Neuropsychiatric Reaction in a Deployed Military Member after Prophylactic Mefloquine

Directory of Open Access Journals (Sweden)

Alan L. Peterson

2011-01-01

Full Text Available Recent studies of military personnel who have deployed to Iraq and Afghanistan have reported a number of combat-related psychiatric disorders such as posttraumatic stress disorder, depression, and traumatic brain injury. This case report involves a 27-year-old male active-duty US military service member who developed severe depression, psychotic hallucinations, and neuropsychological sequelae following the prophylactic use of the antimalarial medication mefloquine hydrochloride. The patient had a recent history of depression and was taking antidepressant medications at the time of his deployment to the Middle East. Psychiatrists and other health care providers should be aware of the possible neuropsychiatric side effects of mefloquine in deployed military personnel and should consider the use of other medications for malaria prophylaxis in those individuals who may be at increased risk for side effects.

The optimal approach is controversial in asymptomatic patients who are coincidentally found to have evidence of an accessory pathway (AP) on an ECG. The risk of sudden cardiac death (SCD) is low, and the risk of developing symptoms also appears to be low, although a wide range of incidences have been reported. In our trial, we tested the hypothesis that if prophylactic accessory-pathway ablation performed at the time of the initial electrophysiological testing would improve the long-term outcome in asymptomatic patients with a Wolff-Parkinson-White electrocardiographic pattern. Recruitment of patients began on February 1, 2004, and ended on February 5, 2009. All 110 asymptomatic patients were hospitalized and underwent electrophysiological testing the same day to assess the inducibility of atrioventricular reciprocating tachycardia. The anterograde effective refractory period of the accessory pathway was defined as the longest coupling interval at which anterograde block in the bypass tract was observed. For the statistical analysis, the statistical software SPSS version 15.0 for Windows (SPSS Inc., Chicago, IL, USA). Of 110 asymptomatic patients with a Wolff-Parkinson-White electrocardiographic pattern, 80 patients were ablated. Ablation group consisted of these patients. Control group consisted of remaining 30 and were divided into two groups according to the anterograde effective refractory period of the accessory pathway. There was no significant difference between three groups in terms of arrhythmic events (p: 0.58). Asymptomatic patients with the Wolff-Parkinson-White syndrome do not require prophylactic ablation, since they remain asymptomatic for many years.

Halpern, Leslie R; Dodson, Thomas B

2007-02-01

To estimate and compare the frequencies of inflammatory complications after third molar (M3) surgery in subjects receiving intravenous prophylactic antibiotics or saline placebo. Using a placebo-controlled, double-blind, randomized clinical trial, the investigators enrolled a sample composed of subjects who required extraction of at least 1 impacted M3 and requested intravenous sedation or general anesthesia. The predictor variable was treatment group classified as active treatment (penicillin or clindamycin for penicillin-allergic subjects) or placebo (0.9% saline). Study medications were randomly assigned. Both surgeon and subject were blinded to treatment assignment. The medication was administered intravenously prior to any incision. The outcome variable was postoperative inflammatory complication classified as present or absent and included alveolar osteitis (AO) or surgical site infection (SSI). Other variables were demographic, anatomic, or operative. Descriptive and bivariate statistics were computed. Statistical significance was set at P < or = .05, single-tailed test of hypothesis. The sample was composed of 118 subjects (n = 59 per study group). In the active treatment group, there were no postoperative inflammatory complications. In the placebo group, 5 subjects (8.5%) were diagnosed with SSI, (P = .03). No subject met the case definition for AO. All SSIs were associated with the removal of partial bony or full bony impacted mandibular M3s. In the setting of third molar removal, these results suggest that the use of intravenous antibiotics administered prophylactically decrease the frequency of SSIs. The authors cannot comment on the efficacy of intravenous antibiotics in comparison to other antibacterial treatment regimens, eg chlorhexidine mouthrinse or intrasocket antibiotics.

Harling, R; Moorjani, N; Perry, C; MacGowan, A P; Thompson, M H

2000-11-01

Septic complications are rare following laparoscopic cholecystectomy if prophylactic antibiotics are given, as demonstrated in previous studies. Antibiotic treatment may be unnecessary and, therefore, undesirable, so we compared two forms of prophylaxis: a cephalosporin antibiotic and bag extraction of the dissected gallbladder. A total of 76 patients undergoing laparoscopic cholecystectomy were randomised to either receive an antibiotic or to have their gallbladder removed from the abdomen in a plastic bag. Complicated cases were excluded. There was a total of 6 wound infections (7.9%), 3 in each of the study groups. All these were associated with skin commensals. There were no other septic complications. Bacteriological studies grouped the organisms isolated from the bile and the wound as potential pathogens and likely commensals. A total of 10 potential pathogens were isolated, 9 of which were found in the group receiving antibiotics. We conclude that septic sequelae of uncomplicated laparoscopic cholecystectomy are uncommon, but clearly not entirely prevented by antibiotic or mechanical prophylaxis. Prophylactic antibiotics may not be required in uncomplicated laparoscopic cholecystectomy. Further study is warranted.

Prophylactic infusion of clotting factor concentrates is a developing standard of care for individuals with haemophilia. The ideal schedule and techniques of prophylactic infusions remain incompletely defined. Our aim was to determine the optimal techniques and schedules for factor prophylaxis in paediatric patients. A retrospective electronic medical record review of all children treated with prophylactic factor infusions in a single Haemophilia Treatment Center was conducted. Comparison of traditional vs. Canadian dosing regimens and primary vs. secondary prophylaxis was made. Failure of prophylaxis was defined as the first serious bleed. A total of 58 children were identified for review. Five cases were excluded (four due to high titre inhibitors and one due to repeated non-compliance), thus there were 53 total cases: 46 with severe haemophilia, 2 with moderate haemophilia, 5 with mild haemophilia, 44 with haemophilia A and 9 with haemophilia B; 32 Traditional dosing and 21 Canadian dosing regimens. Patients on primary prophylaxis had a decreased failure rate (25%) compared to children treated with secondary prophylaxis (67%) regardless of technique of prophylaxis. When compared to a 'Traditional' factor prophylaxis schedule, the 'Canadian' tailored prophylaxis protocol was comparable with the exception of a decreased use of implanted venous devices in the 'Canadian' group. Ongoing bleeding (primarily joint bleeds) occurs with all prophylactic regimens. The lowest incidence of treatment failure was noted in children who began primary prophylaxis at a young age and before initial joint bleeds. Primary prophylaxis is superior to secondary prophylaxis regardless of dosing regimen. Traditional and Canadian dosing regimens were equivalent in outcome when measured over several years of follow-up. © 2012 Blackwell Publishing Ltd.

Edwards, R K; Duff, P

1999-01-01

OBJECTIVE: To determine if amnioinfusion with an antibiotic solution decreased the rate of clinical chorioamnionitis and puerperal endometritis in patients with meconium-stained amniotic fluid. METHODS: Patients in labor at 36 weeks of gestation or greater with singleton pregnancies and meconium-stained amniotic fluid were randomized to receive either cefazolin, 1 g/1,000 mL, of normal saline (n = 90) or normal saline (n = 93) amnioinfusion. Rates of clinically diagnosed chorioamnionitis and endometritis and of suspected and culture-proven neonatal infection were determined. RESULTS: Between the study and control groups, the incidences of clinical chorioamnionitis (7.8% vs. 8.6%), endometritis (2.4% vs. 3.5%), aggregate intrauterine infection (10.0% vs. 11.8%), suspected neonatal infection (17.8% vs. 21.5%), and proven neonatal infection (0.0% vs. 2.2%) were not significantly different. CONCLUSIONS: Prophylactic use of cefazolin in amnioinfusions did not significantly reduce rates of maternal or neonatal infection in patients with meconium-stained amniotic fluid. PMID:10371474

Many polishing protocols have been evaluated in vitro for their effect on the surface roughness of restorative materials. These results have been useful in establishing protocols for in vivo application. However, limited research has focused on the subsequent care and maintenance of esthetic restorations following their placement. This investigation evaluated the effect of five polishing protocols that could be implemented at recall on the surface roughness of five direct esthetic restorative materials. Specimens (n=25) measuring 8 mm diameter x 3 mm thick were fabricated in an acrylic mold using five light-cured resin-based materials (hybrid composite, microfilled composite, packable composite, compomer and resin-modified glass ionomer). After photopolymerization, all specimens were polished with Sof-Lex Disks to produce an initial (baseline) surface finish. All specimens were then polished with one of five prophylactic protocols (Butler medium paste, Butler coarse paste, OneGloss, SuperBuff or OneGloss & SuperBuff). The average surface roughness of each treated specimen was determined from three measurements with a profilometer (Surface 1). Next, all specimens were brushed 60,000 times at 1.5 Hz using a brush-head force of 2 N on a Manly V-8 cross-brushing machine in a 50:50 (w/w) slurry of toothpaste and water. The surface roughness of each specimen was measured after brushing (Surface 2) followed by re-polishing with one of five protocols, then final surface roughness values were determined (Surface 3). The data were analyzed using repeated measures ANOVA. Significant differences (p=0.05) in surface roughness were observed among restorative materials and polishing protocols. The microfilled and hybrid resin composite yielded significantly rougher surfaces than the other three materials following tooth brushing. Prophylactic polishing protocols can be used to restore a smooth surface on resin-based esthetic restorative materials following simulated tooth

Objective Naratriptan has been reported to reduce the frequency of cluster headache. The purpose of this study was to determine whether naratriptan is effective as a prophylactic treatment for cluster headache in Japan. Methods We retrospectively reviewed all 43 patients with cluster headache who received preventive treatment with naratriptan from April 2009 to April 2015. The International Classification of Headache Disorders, 3rd Edition (beta version) (ICHD-3 beta) was used to diagnose cluster headache. This study was conducted at 3 centers (Department of Neurology, Saitama Medical University; Saitama Neuropsychiatric Institute; Saitama Medical University International Medical Center). Patients were recruited from these specialized headache outpatient centers. Naratriptan was taken before the patient went to bed. Results The study population included 30 men (69.8%) and 13 women (30.2%). Twenty-two cases received other preventive treatments (51.2%), while 21 cases only received naratriptan (48.8%). Among the 43 cases, 37 patients (86.0%) achieved an improvement of cluster headache on naratriptan. Conclusion Naratriptan has been suggested as a preventive medicine for cluster headache because of the longer the biological half-life in comparison to other triptans. The internal use of naratriptan 2 hours before attacks appears to achieve a good response in patients with cluster headache.

Prophylactic Appendectomy during Laparoscopic Surgery for Other Conditions

Full Text Available Acute appendicitis remains the most common surgical emergency. Laparoscopy has gained increasing favor as a method of both investigating right iliac fossa pain and treating the finding of appendicitis. A question arises: what to do with an apparent healthy appendix discovered during laparoscopic surgery for other pathology. We present a case of unilateral hydroureteronephrosis complicated with rupture of the renal pelvis, due to gangrenous appendicitis with abscess of the right iliopsoas muscle and periappendicular inflammation in a 67-year-old woman, who underwent laparoscopic right annessiectomy for right ovarian cyst few years earlier, in which a healthy appendix was left inside. There is a lack of consensus in the literature about what to do with a normal appendix. The main argument for removing an apparently normal appendix is that endoluminal appendicitis may not be recognized during surgery, leading to concern that an abnormal appendix is left in place. Because of a lack of evidence from randomized trials, it remains unclear whether the benefits of routine elective coincidental appendectomy outweigh the costs and risks of morbidity associated with this prophylactic procedure. Nevertheless, it appears, from limited data, that women aged 35 years and under benefit most from elective coincidental appendectomy.

Thirty-nine healthy US students without diarrheal disease and who had not received prophylactic or therapeutic antibiotics were monitored for emergence of trimethoprim-resistant gram-negative fecal flora for a 3-week period after arrival in Guadalajara, Mexico. During this time period, most students showed no change in total fecal gram-negative bacteria (p > 0.05) but showed an increasing level of trimethoprim (TMP) resistance (p students. These 18 TMP-resistant E. coli were also resistant to ampicillin (44%), azithromycin (11%), chloramphenicol (39%), ciprofloxacin (11%), doxycycline (89%), erythromycin (100%), furazolidone (72%), levofloxacin (17%), trimethoprim-sulfamethoxazole (89%) and trovafloxacin (17%). In the absence of prophylactic and therapeutic antibiotics, increased acquisition of TMP-resistant gram-negative fecal flora in this developing country is probably due to poor sanitary conditions and the recurrent and heavy exposure to antimicrobial-resistant indigenous flora as a result of contaminated food and drink.

Full Text Available Aim. To identify possible predictors of atrial fibrillation (AF recurrence in 6-month prophylactic propafenone therapy. Material and methods. Patients (n=63; aged 52.2±12.6 years; 25.4% women with frequent AF recurrences who restored sinus rhythm with propafenone, were included into the study. Paroxysmal AF was observed in 84.1% of patients, and persistent AF — in 15.9% of patients. ECG, transthoracic echocardiography , chest radiography with the calculation of cardio-thoracic index (CTI was performed at baseline. All patients received rpropafenone therapy (450–600 mg/day during 6 months after sinus rhythm conversion. ECG and 24-hours ECG monitoring were performed in 1, 3 and 6 months of the therapy. Patients with 70–100% reduction in AF recurrence rate were included into the 1-st group, and patients with <70% reduction – into the 2-nd group. Results. 92%, 88.5% and 78% of patients were included into the group 1 after 1, 3 and 6 months of follow up, respectively. AF recurrences were observed 4.5, 3.8, and 1.7 times more often in women than these in men after 1, 3 and 6 months, respectively , (p>0.05. Mean age of patients in the group 2 was significantly older than this in patients of the group 1 (p<0.05. CTI, left atrium size and volume, interventricular septum thickness (IVST were significantly larger in group 2. Myocardium mass of the left ventricle (MMLV after 6 months of therapy was larger by 13.9% in patients of the group 2 vs this in patients of the group 1 (p<0.05. Conclusion. Insufficient preventive effect of propafenone was observed in 8%, 11.5% and 22% of patients in 1, 3 and 6 months of the follow-up, respectively. Propafenone prophylactic efficacy was slightly higher in men and younger patients. Patients with poor preventive effect of propafenone had a significantly larger baseline CTI, size and volume of the left atrium, IVST, and MMLV.

There will be a continued imperative to recruit large numbers of healthy volunteers to early phase prophylactic HIV vaccine (PHV) trials. We studied mechanisms associated with participation in two related phase II PHV trials. The most cited reasons for volunteering were altruism and a personal connection to HIV. The most successful recruiting strategies targeted organisations dealing with HIV, health or social issues, or were directed to large audiences through the mass media. However, circulated emails and word of mouth were the most resource-effective approaches. Group discussions and the collection of a pool of potential volunteers were much less effective than one-to-one discussions and immediate screening after recruitment. We utilised our findings to devise key recommendations to assist PHV trial teams who are planning future studies.

Lynch syndrome and chronic inflammatory bowel disease are two important risk factors for colorectal cancer. It is unclear whether Lynch syndrome patients with inflammatory bowel disease are at sufficiently increased risk for colorectal cancer to warrant prophylactic colectomy. This study aims to identify all cases of Lynch syndrome and concurrent inflammatory bowel disease in a large familial gastrointestinal cancer registry, define incidence of colorectal cancer, and characterize mismatch repair protein gene mutation status and inflammatory bowel disease-associated colorectal cancer risk factors. We retrospectively identified and collected clinical data for all cases with confirmed diagnoses of Lynch syndrome and inflammatory bowel disease in the Familial Gastrointestinal Cancer Registry at Mount Sinai Hospital in Toronto, Canada. Twelve cases of confirmed Lynch syndrome, and concurrent inflammatory bowel disease were identified. Four cases developed colorectal cancer. An additional five cases had colectomy; one was performed for severe colitis, and four were performed for low-grade dysplasia. None of these surgical specimens contained malignancy or high-grade dysplasia. The presentation of Lynch syndrome with inflammatory bowel disease is uncommon and not well described in the literature. This small but important series of twelve cases is the largest reported to date. In this series, patients with Lynch syndrome and concurrent inflammatory bowel disease do not appear to have sufficiently increased risk for colorectal cancer to recommend prophylactic surgery. Therefore, the decision to surgery should continue to be guided by surgical indications for each disease. Further evaluation of this important area will require multi-institutional input.

Inflammation plays a role in the pathophysiology of depression. Sulforaphane (SFN), an isothiocyanate compound derived from broccoli, is a potent activator of the NF-E2-related factor-2 (Nrf2), which plays a role in inflammation. In this study, we examined whether the prevention effects of SFN in lipopolysaccharide (LPS) induced depression-like behavior in mice. Pretreatment with SFN significantly blocked an increase in the serum tumor necrosis factor-α (TNF-α) level and an increase in microglial activation of brain regions after a single administration of LPS (0.5 mg/kg). Furthermore, SFN significantly potentiated increased serum levels of IL-10 after LPS administration. In the tail-suspension test and forced swimming test, SFN significantly attenuated an increase of the immobility time after LPS administration. In addition, SFN significantly recovered to control levels for LPS-induced alterations in the proteins such as brain-derived neurotrophic factor, postsynaptic density protein 95 and AMPA receptor 1 (GluA1) and dendritic spine density in the brain regions. Finally, dietary intake of 0.1% glucoraphanin (a glucosinolate precursor of SFN) food during the juvenile and adolescence could prevent the onset of LPS-induced depression-like behaviors and dendritic spine changes in the brain regions at adulthood. In conclusion, these findings suggest that dietary intake of SFN-rich broccoli sprout has prophylactic effects on inflammation-related depressive symptoms. Therefore, supplementation of SFN-rich broccoli sprout could be prophylactic vegetable to prevent or minimize the relapse by inflammation in the remission state of depressed patients.

Full Text Available In 2008/2009, at the time of influenza epidemic, the study of ambulatory prophylactic treatment of fusafungine (Bioparox in 50 children 7–15 years old with chronic tonsillitis was performed. All these children underwent regular ENT check-up. The control group included 50 schoolchildren the same age without chronic diseases of upper airways. After the treatment with intranasal fusafungine, the amount of patients with Streptococcus pyogenes was decreased 1,6 times low (and after 3 months of treatment it was decreased 3,5 times low. The sanation of palatine tonsils from Candida albicans was detected (eradication of microorganism was achieved in 58% of cases, and the amount of patients with pharyngomycosis was decreased 2,4 times low. Patient’s quality of life significantly increased, and ENT-specialists met less complaints (in 4,5–15 times low.

Fatigue is the most common toxicity of all grade toxicities with regorafenib, was the second most common toxicity in the CORRECT (regorafenib monotherapy for previously treated metastatic colorectal cancer) study, and is a major reason for early dose modification. The results from a recent randomized study suggested that dexamethasone (DEX) can improve cancer-related fatigue. We retrospectively analyzed the effect of prophylactic use of an oral DEX on fatigue during regorafenib treatment in patients with metastatic colorectal cancer (mCRC). A total of 105 patients who had received regorafenib at our institution from May 2013 to August 2014 were divided into 2 groups according to oral DEX use (2 mg/day; at the physician's discretion). Of the 105 patients, 31 received prophylactic DEX and 74 received regorafenib alone. The time to dose modification was significantly longer in the DEX group than in the no DEX group (15 days vs. 9 days; P = .009). The incidence of fatigue (grade ≥ 1) was significantly lower with DEX than without DEX (25.8% vs. 50.0%; P = .022). Fewer patients experienced a decreased appetite (grade ≥ 1; 3.2% vs. 35.1%; P regorafenib treatment, resulting in prolonging the time to dose modification for regorafenib. The decreased incidence of appetite loss and HFSR also suggest that concurrent DEX administration with regorafenib warrants further investigation. Copyright © 2016 Elsevier Inc. All rights reserved.

Giardiasis is a re-emerging infectious disease with outbreaks reported globally specially in children and malnourished individuals leading to malabsorption, growth retardation, and severe diarrhea. Thus, in the present study, prophylactic administration of synbiotic as the functional food was used to assess its antigiardial potential in malnourished murine giardiasis. Interestingly, prior administration of synbiotic (Lactobacillus casei + inulin) even to malnourished-Giardia-infected mice led to increased body mass, small intestine mass, lactobacilli counts, and reduced severity of giardiasis as evident by decreased cyst and trophozoite counts. Synbiotic therapy further boosted the innate and acquired immune response resulting into increase in nitric oxide, antigiardial secretory IgA and IgG antibody levels along with IL-6 and IL-10 cytokines, and decreased levels of inflammatory TNF-α cytokine in both serum and intestinal fluid in malnourished-synbiotic-Giardia-infected mice compared with malnourished-Giardia-infected mice. More specifically, histopathological and scanning electron microscopy analysis of the small intestine also confirmed the modulatory potentials of synbiotic in malnourished-synbiotic-Giardia mice which had less cellular and mucosal damage compared with severely damaged, mummified, and blunted villi in malnourished-Giardia-infected mice. Taken together, this is the first experimental study to report that prior supplementation of synbiotic restored the gut morphology and improved the immune status of the malnourished-Giardia-infected mice, and could be considered as the prophylactic adjunct therapy for malnourished individuals.

The effect of prophylactic digitalization on the development of left ventricular hypertrophy was studied in adult rats. Digitoxin, 0.1 mg/100 g body wt or solvent was given daily for 1 wk prior to either aortic constriction or sham operation and was continued until the animals were killed, either 1 or 4 wk after surgery. A hemodynamic study was done in those animals killed 1 wk after surgery; hearts of all animals were examined for evidence of myocardial hypertrophy. Constriction of the ascending aorta had no significant effect on cardiac output but did reduce peak flow velocity and flow acceleration. An increase in left ventricular mass, RNA, and hydroxyproline was found in the animals with aortic constriction. Digitoxin treatment did not alter peak flow velocity or flow acceleration, but did significantly increase isovolumic (dP/dt)P-1. Digitoxin had no effect on body weight, heart weight, RNA, or hydroxyproline in either the sham-operated animals or in the animals with aortic constriction. Therefore, despite plasma digitoxin levels sufficient to affect myocardial contractility, left ventricular hypertrophy still developed after aortic constriction.

: Severe hereditary factor VII deficiency is a rare bleeding disorder and may be associated with a severe bleeding phenotype. We describe a pregnancy in a 33-year-old woman with compound heterozygous factor VII deficiency and a history of severe menorrhagia and mucocutaneous bleedings. After discontinuation of contraceptives, menstruation was covered with recombinant activated factor VII (rFVIIa), and during pregnancy, rFVIIa had to be administered in first trimester in doses ranging from 15 to 90 μg/kg per day because of recurrent retroplacental hematomas and vaginal bleedings. Thrombin generation was measured in first trimester at different doses of rFVIIa and showed an increase in lag time when doses of less than 30 μg/kg/day were administered, whereas time to thrombin peak and peak thrombin were not influenced. A low-dose rFVIIa prophylactic treatment of 15 μg/kg every other day in the late second and in the third trimester was sufficient to allow a successful childbirth in this patient with severe factor VII deficiency.

Introduction Hemophilia A individuals displaying a similar genetic defect have heterogeneous clinical phenotypes. Aim To evaluate the underlying effect of exogenous factor (f)VIII on tissue factor (Tf)-initiated blood coagulation in severe hemophilia utilizing both empirical and computational models. Methods We investigated twenty-five clinically severe hemophilia A patients. All individuals were on fVIII prophylaxis and had not received fVIII from 0.25 to 4 days prior to phlebotomy. Coagulation was initiated by the addition of Tf to contact-pathway inhibited whole blood ± an anti-fVIII antibody. Aliquots were quenched over 20 min and analyzed for thrombin generation and fibrin formation. Coagulation factor levels were obtained and used to computationally predict thrombin generation with fVIII set to either zero or its value at the time of the draw. Results Due to prophylactic fVIII, at the time of the blood draw, the individuals had fVIII levels that ranged from hemophilia A. The combination of each individual's coagulation factors (outside of fVIII) determine each individual's baseline thrombin potential and may affect bleeding risk. PMID:21899664

Recruitment of volunteers is one of the main challenges in clinical trial management, and there is little information about recruitment barriers for preventative vaccine trials. We investigated both the recruitment barriers and recruitment strategies for preventive vaccine trials in Belgium. A 10 min survey was used as well as interviews of staff at all clinical trial sites in Belgium that regularly perform vaccine trials. We observed that there are successful recruitment strategies and few recruitment issues for trials involving healthy adults and those over 65 years old. However, challenges face the recruitment of paediatric populations, pregnant women, patients and the very elderly (over 85 years old). From these results, we identified three priority areas to increase recruitment for prophylactic vaccine trials in Belgium. These are: the lack of public knowledge about infectious diseases; the lack of resources of healthcare professionals to take part in clinical trials; and the burden to potential volunteers to take part in a trial. These were discussed with stakeholders and solutions were proposed. Copyright © 2017 Elsevier Ltd. All rights reserved.

Purpose: To report outcomes of patients with localized intracranial germinoma treated with low-dose craniospinal irradiation (CSI) followed by a boost to the ventricular system and primary site. Methods and Materials: Thirty-one patients had pathologically confirmed intracranial germinoma and no spine metastases. Low-dose CSI was administered in 29 patients: usually 21 Gy of CSI, 9.0 Gy of ventricular boost, and a 19.5-Gy tumor boost, all at 1.5 Gy per fraction. Our neuroradiologist recorded three-dimensional tumor size on magnetic resonance images before, during, and after radiotherapy. Results: With a median follow-up of 7.0 years, 29 of 31 patients (94%) are disease free. One failure had nongerminomatous histology; the initial diagnosis was a sampling error. Of 3 patients who did not receive CSI, 1 died. No patient developed myelopathy, visual deficits, dementia, or skeletal growth problems. In locally controlled patients, tumor response according to magnetic resonance scan was nearly complete within 6 months after radiotherapy. Conclusions: Radiotherapy alone with low-dose prophylactic CSI cures almost all patients with localized intracranial germinoma. Complications are rare when the daily dose of radiotherapy is limited to 1.5 Gy and the total CSI dose to 21 Gy. Patients without a near-complete response to radiotherapy should undergo resection to rule out a nongerminomatous element
