    Oral naltrexone has high potential for use as a relapse prevention pharmacotherapy for opiate dependence yet suffers from notoriously poor adherence. This study evaluated whether entry to a therapeutic workplace could reinforce adherence with oral naltrexone. Opiate-dependent and cocaine-using injection drug users were detoxified, inducted onto oral naltrexone, and randomly assigned to a contingency (n = 35) or prescription (n = 32) group for a 26-week period. Contingency participants were required to ingest naltrexone under staff observation to gain access to the therapeutic workplace. Prescription participants received a take-home supply of naltrexone and could access the workplace independent of naltrexone ingestion. Primary outcome measures were percent of urine samples positive for naltrexone at 30-day assessments and negative for opiates and cocaine at 30-day assessments. Contingency participants provided significantly more urine samples that were positive for naltrexone compared with prescription participants (72% vs. 21%, p workplace significantly promoted adherence to oral naltrexone, and that the majority of opiate use occurred in conjunction with cocaine use, suggesting that untreated cocaine use may limit the effectiveness of oral naltrexone in promoting opiate abstinence.

    Oral naltrexone could be a promising relapse-prevention pharmacotherapy for recently detoxified opioid-dependent patients; however, interventions are often needed to promote adherence with this treatment approach. We recently conducted a study to evaluate a 26-week employment-based reinforcement intervention of oral naltrexone in unemployed injection drug users (Dunn et al., 2013). Participants were randomly assigned into a contingency (n = 35) group required to ingest naltrexone under staff observation to gain entry into a therapeutic workplace or a prescription (n = 32) group given a take-home supply of oral naltrexone and access to the workplace without observed ingestion. Monthly urine samples were collected and analyzed for evidence for naltrexone adherence, opioid use, and cocaine use. As previously reported, contingency participants provided significantly more naltrexone-positive urine samples than prescription participants during the 26-week intervention period. The goal of this current study is to report the 12-month outcomes, which occurred 6 months after the intervention ended. Results at the 12-month visit showed no between-groups differences in naltrexone-positive, opioid-negative, or cocaine-negative urine samples and no participant self-reported using naltrexone at the follow-up visit. These results show that even after a period of successfully reinforced oral naltrexone adherence, longer-term naltrexone use is unlikely to be maintained after reinforcement contingencies are discontinued.

    We investigated prescribing patterns for four opioid use disorder (OUD) medications: 1) injectable naltrexone, 2) oral naltrexone, 3) sublingual or oralmucosal buprenorphine/naloxone, and 4) sublingual buprenorphine as well as transdermal buprenorphine (which is approved for treating pain, but not OUD) in a nationally representative claims-based database (Truven Health MarketScan®) of commercially insured individuals in the United States. We calculated the prevalence of OUD in the database for each year from 2010 to 2014 and the proportion of diagnosed patient months on OUD medication. We compared characteristics of individuals diagnosed with OUD who did and did not receive these medications with bivariate descriptive statistics. Finally, we fit a Cox proportional hazards model of time to discontinuation of therapy as a function of therapy type, controlling for relevant confounders. From 2010 to 2014, the proportion of commercially insured individuals diagnosed with OUD grew by fourfold (0.12% to 0.48%), but the proportion of diagnosed patient-months on medication decreased from 25% in 2010 (0.05% injectable naltrexone, 0.4% oral naltrexone, 23.1% sublingual or oralmucosal buprenorphine/naloxone, 1.5% sublingual buprenorphine, and 0% transdermal buprenorphine) to 16% in 2014 (0.2% injectable naltrexone, 0.4% oral naltrexone, 13.8% sublingual or oralmucosal buprenorphine/naloxone, 1.4% sublingual buprenorphine, and 0.3% transdermal buprenorphine). Individuals who received medication therapy were more likely to be male, younger, and have an additional substance use disorder compared with those diagnosed with OUD who did not receive medication therapy. Those prescribed injectable naltrexone were more often male, younger, and diagnosed with additional substance use disorders compared with those prescribed other medications for opioid use disorder (MOUDs). At 30 days after initiation, 52% for individuals treated with injectable naltrexone, 70% for individuals treated

    Morphine sulfate/sequestered naltrexone hydrochloride (HCl) (MS-sNT) extended-release fixed-dose combination capsules, approved by the US Food and Drug Administration (FDA) in August 2009 for chronic moderate to severe pain, contain extended-release morphine pellets with a sequestered core of the opioid antagonist naltrexone. MS-sNT was designed so that if the product is tampered with by crushing, the naltrexone becomes bioavailable to mitigate morphine-induced subjective effects, rendering the product less attractive for tampering. The primary aim of this study was to compare the oral bioavailability of naltrexone and its metabolite 6-beta-naltrexol, derived from crushed pellets from MS-sNT capsules, to naltrexone solution. This study also assessed the relative bioavailability of morphine from crushed pellets from MS-sNT capsules and that from the whole, intact product. This single-dose, randomized-sequence, open-label, 3-period, 3-treatment crossover trial was conducted in healthy volunteers. Adults admitted to the study center underwent a 10-hour overnight fast before study drug administration. Each subject received all 3 of the following treatments, 1 per session, separated by a 14-day washout: tampered pellets (crushed for >or=2 minutes with a mortar and pestle) from a 60-mg MS-sNT capsule (60 mg morphine/2.4 mg naltrexone); 60-mg whole, intact MS-sNT capsule; and oral naltrexone HCl (2.4 mg) solution. Plasma concentrations of naltrexone and 6-beta-naltrexol were measured 0 to 168 hours after administration. Morphine pharmaco-kinetics of crushed and whole pellets were determined 0 to 72 hours after administration. The analysis of relative bioavailability was based on conventional FDA criteria for assuming bioequivalence; that is, 90% CIs for ratios of geometric means (natural logarithm [In]-transformed C(max) and AUC) fell within the range of 80% to 125%. Subjects underwent physical examinations, clinical laboratory tests, and ECG at screening and study

    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)

    that sometimes includes the administration of psychotropic medication. One of these children presented with a severe autistic disorder according to the Childhood Autism Rating Scale (CARS). Considering ICD-10 criteria, he benefited from a multidisciplinary program, associating cognitive psychotherapy, psychomotor rehabilitation, speech therapy and educational intervention. However, persistent sleep disorder and motor instability led to successive prescriptions of several different psychotropic drugs. Initial treatment by thioridazine (10mg per day) followed by propericiazine (2.5mg per day) improved sleep, but was not efficient in reducing self-mutilating behaviour. A new treatment by risperidone (from 0.5mg to 1.5mg per day) was therefore chosen; however it lost its efficacy after five months. Finally, an anxiolytic (cyamemazine) and a thymoregulator (sodium valproate) were successively tried without yielding any clinical improvement. Owing to the persistence of communication difficulties, major instability, self-mutilating behaviour and heteroaggressiveness, treatment with naltrexone was subsequently chosen with parental consent. In France, naltrexone hydrochloride is only available in tablet form (Nalorex 50mg and Revia 50mg), which is not adapted to children at the efficient dose. Consequently, an oral suspension form marketed in Spain (Antaxone 50mg) was imported, having obtained the Afssaps' (the French drug administration) authorisation for its temporary use. The Connors and Nisonger scales were used as outcome measures of behavioural symptom change. The Conners scale is used to assess attention deficit and hyperactivity, whereas the Nisonger scale analyses social skills and behaviour disorders in children and adolescents with mental retardation. The onset of treatment, at a dose of 1mg/kg/day, led to a transitory increase in negative behaviour. However, a dose of 0.75mg/kg per day subsequently led to significant improvements, as shown by outcome measurements

    Naltrexone can be used to treat opioid dependence, but patients refuse to take it. Extended-release depot formulations may improve adherence, but long-term adherence rates to depot naltrexone are not known. This study determined long-term rates of adherence to depot naltrexone and whether employment-based reinforcement can improve adherence. Participants who were inducted onto oral naltrexone were assigned randomly to contingency (n = 18) or prescription (n = 17) groups. Participants were offered six depot naltrexone injections and invited to work at the therapeutic workplace on week days for 26 weeks, where they earned stipends for participating in job skills training. Contingency participants were required to accept naltrexone injections to maintain workplace access and to maintain maximum pay. Prescription participants could work independently of whether they accepted injections. The therapeutic workplace, a model employment-based intervention for drug addiction and unemployment. Opioid-dependent unemployed adults. Depot naltrexone injections accepted and opiate-negative urine samples. Contingency participants accepted significantly more naltrexone injections than prescription participants (81% versus 42%), and were more likely to accept all injections (66% versus 35%). At monthly assessments (with missing urine samples imputed as positive), the groups provided similar percentages of samples negative for opiates (74% versus 62%) and for cocaine (56% versus 54%). Opiate-positive samples were more likely when samples were also positive for cocaine. Employment-based reinforcement can maintain adherence to depot naltrexone. Future research should determine whether persistent cocaine use compromises naltrexone's effect on opiate use. Workplaces may be useful for promoting sustained adherence to depot naltrexone. © 2011 The Authors, Addiction © 2011 Society for the Study of Addiction.

    Kleptomania is a rare psychiatric disorder characterized by recurrent stealing and for which there exists no empirically validated treatments. This study examined the efficacy and tolerability of the opioid antagonist naltrexone in adults with kleptomania who have urges to steal. An 8-week, double-blind, placebo-controlled trial was conducted to evaluate the safety and efficacy of oral naltrexone for kleptomania. Twenty-five individuals with DSM-IV kleptomania were randomized to naltrexone (dosing ranging from 50 mg/day to 150 mg/day) or placebo. Twenty-three subjects (92%) completed the study. Subjects were assessed every 2 weeks with the Yale Brown Obsessive Compulsive Scale Modified for Kleptomania (K-YBOCS), the urge and behavior subscales of the K-YBOCS, the Kleptomania Symptom Assessment Scale (K-SAS), the Clinical Global Impressions Scale (CGI), and measures of depression, anxiety, and psychosocial functioning. Subjects assigned to naltrexone had significantly greater reductions in K-YBOCS total scores (p = .001), stealing urges (p = .032), and stealing behavior (p kleptomania severity (reflected in the CGI scores) (p kleptomania. Naltrexone was well tolerated.

    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)

    Abstract Naltrexone, an opioid receptor antagonist, is commonly used as a relapse prevention medication in alcohol and opiate addiction, but its efficacy and the mechanisms underpinning its clinical usefulness are not well characterized. In the current study, we examined the effects of 50‐mg naltrexone compared with placebo on neural network changes associated with substance dependence in 21 alcohol and 36 poly‐drug‐dependent individuals compared with 36 healthy volunteers. Graph theoretic and network‐based statistical analysis of resting‐state functional magnetic resonance imaging (MRI) data revealed that alcohol‐dependent subjects had reduced functional connectivity of a dispersed network compared with both poly‐drug‐dependent and healthy subjects. Higher local efficiency was observed in both patient groups, indicating clustered and segregated network topology and information processing. Naltrexone normalized heightened local efficiency of the neural network in alcohol‐dependent individuals, to the same levels as healthy volunteers. Naltrexone failed to have an effect on the local efficiency in abstinent poly‐substance‐dependent individuals. Across groups, local efficiency was associated with substance, but no alcohol exposure implicating local efficiency as a potential premorbid risk factor in alcohol use disorders that can be ameliorated by naltrexone. These findings suggest one possible mechanism for the clinical effects of naltrexone, namely, the amelioration of disrupted network topology. PMID:28247526

    Full Text Available Background: Naltrexone is a competitive opioid receptor antagonist blocking the euphoric effects of exogenous opioids. When used concomitantly with opioids, naltrexone causes severe withdrawal symptoms. The main aim of the study is to determine the symptomatology and outcome of patients who consumed naltrexone in conjunction with an opioid substance. Methods: This cross-sectional study was performed on the patients hospitalized with history of naltrexone usage coincided with opioid substances at Razi Hospital, Rasht, Iran. The collected data were demographic information, abuse information, clinical signs and symptoms, laboratory findings, and therapeutic measures taken. Data analysis was performed by descriptive tests using SPSS software version 16. Results: The mean age of the patients was 33.7±10.2. The majority of the cases were male (95.6% and urban (96.7%. The main cause of withdrawal symptoms in 91.1% of the patients was inappropriate naltrexone usage. The main poisoning agent in 80% of the cases was consumed naltrexone alone. The route of consumption in 90.1% of the cases was oral and in 9.9% the cases was IV injection. The major clinical features were nausea, vomiting, and agitation. The main therapeutic measures were supportive intravenous fluids (94.8% and opioid administration in the form of methadone. The mean hospitalization period was 21.8±18 hours. Conclusion: Severity, clinical course, and outcome of opioid withdrawal by accidental or intentional naltrexone abuse varies greatly among patients and is unpredictable. Common findings upon presentation were gastrointestinal symptoms and agitation and the main therapeutic measures for these patients were support with intravenous fluids and anti-nausea drugs administration as plasil and opioid administration as methadone.

    Malfunctioning of the brain's reward center is increasingly understood to underlie all addictive behavior. Composed of mesolimbic incentive salience circuitry, the reward center governs all behavior in which motivation has a central role, including acquiring food, nurturing young, and having sex. To the detriment of normal functioning, basic survival activities can pale in importance when challenged by the allure of addictive substances or behaviors. Dopamine is the neurotransmitter driving both normal and addictive behavior. Other neurotransmitters modulate the amount of dopamine released in response to a stimulus, with the salience determined by the intensity of the dopamine pulse. Opiates (either endogenous or exogenous) exemplify such modulators. Prescribed for treating alcoholism, naltrexone blocks opiates' capacity to augment dopamine release. This article reviews naltrexone's mechanism of action in the reward center and describes a novel use for naltrexone in suppressing a euphorically compulsive and interpersonally devastating addiction to Internet pornography.

    Co-occurring addictive disorders are common, however treatment strategies for this population have not been extensively studied. This is especially the case for behavioral addictions. We present a patient (N = 1) with tobacco use disorder and problematic pornography use treated with naltrexone. Naltrexone treatment resulted in a decrease in pornography viewing and cigarette smoking, however had the adverse effect of anhedonia. A lower dose modestly impacted pornography viewing but not smoking. Relevant literature regarding co-occurring addictions as well as use of naltrexone is reviewed. This report represents the first case of tobacco and pornography co-addiction in the literature and supports the assertion that treatment of one addictive disorder can benefit another in the dually addicted patient. The efficacy of naltrexone for smoking is notable as previous studies of naltrexone in smoking have been disappointing. This case suggests future treatment strategies for comorbid addictions.

    Selective chemoaffinity ligands to aid in identification and purification of opioid receptor subtypes were prepared from 6α- and 6β-naltrexol, obtained stereoselectively from the μ-receptor antagonist naltrexone. The targets were the 6α- and 6β-methacrylate ethers and 6α- and 6β-methacrylate esters prepared from reaction of 6α- and 6β-naltrexol with methyl α-(bromomethyl)acrylate or methacryloyl chloride. Of three methacrylate derivatives, the 6α-ether was the most potent in an opioid receptor binding assay with [ 3 H]-naltrexone. In the presence of sodium ion, preincubation of the 6α-ether resulted in recovery of about 60% of original [ 3 H]-naltrexone binding suggesting some irreversible effects. The methacrylate esters precipitated withdrawal in morphine dependent monkeys. The enantiomers of verapamil, a calcium channel antagonist, have different pharmacological and pharmacokinetic properties. The oxidative metabolism of verapamil was studied in rat and human liver microsomes and in man after a single oral dose

    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.

    Compulsive sexual behavior (CSB) is generally characterized by recurrent and intense sexually arousing fantasies, sexual urges, and behaviors, which cause individuals distress or impair daily functioning. Descriptive studies of individuals with paraphilic and nonparaphilic CSB indicate that they experience urges to engage in problematic sexual behavior. The opiate antagonist naltrexone has been successfully used to treat a number of disorders in which urges to engage in problematic behavior are a central feature, such as alcoholism. We hypothesized that naltrexone would reduce the urges and behaviors associated with CSB. Records of 19 male patients with CSB who were treated with naltrexone at an outpatient adult sexual health clinic were retrospectively reviewed. Nearly all patients were already taking other psychotropic medications when naltrexone was initiated. Seventeen (89%) of the 19 patients reported a reduction in CSB symptoms when taking naltrexone for a period ranging from 2 months to 2.3 years, as judged by Clinical Global Impression scores of 1 or 2, indicating "very much improved" or "much improved." Five (26%) of the 19 patients chose to discontinue the medication. Naltrexone may be a useful adjunctive treatment for CSB.

    Naltrexone blocks the opioid receptors that modulate the release of dopamine in the brain reward system and therefore blocks the rewarding effects of heroin and alcohol. It is generally assumed that naltrexone leads to reduction of craving, but few studies have been performed to prove this. The

    The present study attempted to determine the relative role of the peripheral and central nervous system in the production of morphine-induced or radiation-induced locomotor hyperactivity of the mouse. Toward this end, we used a quaternary derivative of an opiate antagonist (naltrexone methobromide), which presumably does not cross the blood-brain barrier. Quaternary naltrexone was used to challenge the stereotypic locomotor response observed in these mice after either an i.p. injection of morphine or exposure to 1500 rads /sup 60/Co. The quaternary derivative of naltrexone reversed the locomotor hyperactivity normally observed in the C57BL/6J mouse after an injection of morphine. It also significantly attenuated radiation-induced locomotion. The data reported here support the hypothesis of endorphin involvement in radiation-induced and radiogenic behaviors. However, these conclusions are contingent upon further research which more fully evaluates naltrexone methobromide's capacity to cross the blood-brain barrier.

    Pathological gambling (PG) is a potential complication related to the treatment of Parkinson disease (PD) with dopamine agonists (DA). The cause of this disorder is unknown, but altered dopamine neurotransmission may be involved. We evaluated the efficacy and tolerability of the opioid antagonist naltrexone in the treatment of PG in PD. Our cases included 3 patients with PD who developed PG after DA treatment. Pathological gambling did not improve after reduction or discontinuation of DA. These patients responded poorly to serotonin reuptake inhibitors, whereas treatment with opioid antagonist naltrexone resulted in the remission of PG. Naltrexone treatment was well tolerated. In one patient, higher dose of naltrexone resulted in hepatic abnormalities, which resolved after dosage reduction. The opioid antagonist naltrexone could be an effective option for the treatment of PG in PD.

    Full Text Available Alcohol use disorder (AUD is a major health, social and economic problem for which there are few effective treatments. The opiate antagonist naltrexone is currently prescribed clinically with mixed success. We have used naltrexone in an established behavioral assay (CAFE in Drosophila melanogaster that measures the flies' preference for ethanol-containing food. We have confirmed that Drosophila exposed to ethanol develop a preference toward this drug and we demonstrate that naltrexone, in a dose dependant manner, reverses the ethanol-induced ethanol preference. This effect is not permanent, as preference for alcohol returns after discontinuing naltrexone. Additionally, naltrexone reduced the alcohol-induced increase in protein kinase C activity. These findings are of interest because they confirm that Drosophila is a useful model for studying human responses to addictive drugs. Additionally because of the lack of a closely conserved opiate system in insects, our results could either indicate that a functionally related system does exist in insects or that in insects, and potentially also in mammals, naltrexone binds to alternative sites. Identifying such sites could lead to improved treatment strategies for AUD.

    Selective chemoaffinity ligands to aid in identification and purification of opioid receptor subtypes were prepared from 6..cap alpha..- and 6..beta..-naltrexol, obtained stereoselectively from the ..mu..-receptor antagonist naltrexone. The targets were the 6..cap alpha..- and 6..beta..-methacrylate ethers and 6..cap alpha..- and 6..beta..-methacrylate esters prepared from reaction of 6..cap alpha..- and 6..beta..-naltrexol with methyl ..cap alpha..-(bromomethyl)acrylate or methacryloyl chloride. Of three methacrylate derivatives, the 6..cap alpha..-ether was the most potent in an opioid receptor binding assay with (/sup 3/H)-naltrexone. In the presence of sodium ion, preincubation of the 6..cap alpha..-ether resulted in recovery of about 60% of original (/sup 3/H)-naltrexone binding suggesting some irreversible effects. The methacrylate esters precipitated withdrawal in morphine dependent monkeys. The enantiomers of verapamil, a calcium channel antagonist, have different pharmacological and pharmacokinetic properties. The oxidative metabolism of verapamil was studied in rat and human liver microsomes and in man after a single oral dose.

    The role of glia in the development and treatment of behavioral abnormalities is understudied. Recent reports have observed glial activation in several disorders, including depression, autism spectrum disorders and self-injurious behaviors (SIB). In the current study, we examined SIB in the physiologically and anatomically relevant nonhuman primate (NHP) model. At the Tulane National Primate Research Center (TNPRC), approximately 5% of singly housed macaques develop symptoms of SIB. We have previously demonstrated that naltrexone hydrochloride can be effective in reducing SIB. We have also demonstrated that the astrocytes of animals with SIB are distinctly atrophic and display heightened innate immune activation compared with control animals. We have added a third group of animals (five macaques identified with SIB and treated with oral naltrexone at a dose of 3.2mg/kg) to the previous cohort (six macaques with a history of SIB but not treated, and nine animals with no history of SIB) for this study. Gray and white matter astrocytes from frontal cortical tissue were examined following necropsy. Innate immune activation of astrocytes, which was increased in SIB animals, was markedly decreased in animals receiving naltrexone, as was atrophy of both grey and white matter astrocytes. This was concomitant with improved behavioral correlates. Preventing astrocyte activation in select areas of the brain to reduce injurious behavior is an innovative concept with implications for mental health studies. Differences in multiple areas of primate brain would help determine how self-injurious behavior develops. These studies suggest a stronger role for astrocytes in the cellular events associated with self-injurious behaviors. Copyright © 2015 Elsevier Inc. All rights reserved.

    Postoperative hypocalcemia is the most common complication after total thyroidectomy. Postoperative parathyroid hormone (PTH) measurement is one of the methods to detect or prevent postoperative hypocalcemia. Prophylactic oral calcium supplementation is another method to prevent early postoperative hypocalcemia. The aim of this study is to detect the accurate timing of PTH and evaluate efficacy of routine oral calcium supplementation for postoperative hypocalcemia. A total of 106 patients were performed total thyroidectomy. Rotuine oral calcium supplementation was given to group 1 and no treatment to group 2 according to randomization. Serum calcium and PTH level of patients in group 2 at postoperative 6, 12 and 24 h and patients in both groups at postoperative day 7 were evaluated. Patients were compared according to age, sex, operation findings, serum calcium and PTH levels and symptomatic hypocalcemia. Half of the patients (50%) were in group 1. Most of the patients were female (83%). The most common etiology of thyroid disease was multinodular goiter (64.1%). Oral calcium supplementation was given to 18 (33.9%) patients in group 2. Symptomatic hypocalcemia for group 1 and 2 was found to be 1.9 and 33.9% respectively (p hypocalcemia. Prophylactic oral calcium supplementation therapy can prevent early post-thyroidectomy hypocalcemia with advantages of being cost effective and safe. Copyright © 2016 IJS Publishing Group Ltd.

    Full Text Available Abstract Background There is on-going controversy in relation to the efficacy of naltrexone used for the treatment of heroin addiction, and the important covariates of that success. We were also interested to review our experience with two depot forms of implantable naltrexone. Methods A retrospective review of patients' charts was undertaken, patients were recalled by telephone and by letter, and urine drug screen samples were collected. Opiate free success (OFS was the parameter of interest. Three groups were defined. The first two were treated in the previous 12 months and comprised "implant" and "tablet" patients. A third group was "historical" comprising those treated orally in the preceding 12 months. Results There were 102, 113 and 161 patients in each group respectively. Groups were matched for age, sex, and dose of heroin used, but not financial status or social support. The overall follow-up rate was 82%. The Kaplan Meier 12 month OFS were 82%, 58% and 52% respectively. 12 post-treatment variables were independently associated with treatment retention. In a Cox proportional hazard multivariate model social support, the number of detoxification episodes, post-treatment employment, the use of multiple implant episodes and spiritual belief were significantly related to OFS. Conclusion Consistent with the voluminous international literature clinically useful retention rates can be achieved with naltrexone, which may be improved by implants and particularly serial implants, repeat detoxification, meticulous clinical follow-up, and social support. As depot formulations of naltrexone become increasingly available such results can guide their clinical deployment, improve treatment outcomes, and enlarge the policy options for an exciting non-addictive pharmacotherapy for opiate addiction.

    Full Text Available Proteoglycan (PG extracted from salmon nasal cartilage has potential to be a prophylactic agent. Daily oral administration of the PG attenuates systemic inflammatory response in the experimental mouse models. In this study, we applied the culture-independent approach to investigate an alteration of intestinal microbiota composition in PG-administered mice. The results indicated that the population level of bacilli increased in the small and large intestine upon PG administration. On the other hand, the population level of clostridia decreased in the large intestine. The proportion of bacteria that are able to ferment saccharides and produce short-chain fatty acids increased in the small intestine and decreased in the large intestine. Importantly, population level of probiotic lactobacilli and bacteria exhibiting the immunomodulatory effect increased in the PG-administered mice. In addition, several disease-associated bacteria decreased upon PG administration. These results provided an understanding of the specific role of PG involved in host immune modulation and supported our hypothesis that daily oral administration of PG improves the overall balance in composition of the intestinal microbial community.

    The purpose of this work was to optimize the structure of codrugs for extended delivery across microneedle treated skin. Naltrexone, the model compound was linked with diclofenac, a nonspecific cyclooxygenase inhibitor to enhance the pore lifetime following microneedle treatment and develop a 7 day transdermal system for naltrexone. Four different codrugs of naltrexone and diclofenac were compared in terms of stability and solubility. Transdermal flux, permeability and skin concentration of both parent drugs and codrugs were quantified to form a structure permeability relationship. The results indicated that all codrugs bioconverted in the skin. The degree of conversion was dependent on the structure, phenol linked codrugs were less stable compared to the secondary alcohol linked structures. The flux of naltrexone across microneedle treated skin and the skin concentration of diclofenac were higher for the phenol linked codrugs. The polyethylene glycol link enhanced solubility of the codrugs, which translated into flux enhancement. The current studies indicated that formulation stability of codrugs and the flux of naltrexone can be enhanced via structure design optimization. The polyethylene glycol linked naltrexone diclofenac codrug is better suited for a 7 day drug delivery system both in terms of stability and drug delivery.

    The objective of the present study was to develop a discriminatory and reproducible accelerated release testing method for naltrexone loaded parenteral polymeric microspheres. The commercially available naltrexone microsphere product (Vivitrol ® ) was used as the testing formulation in the in vitro release method development, and both sample-and-separate and USP apparatus 4 methods were investigated. Following an in vitro drug stability study, frequent media replacement and addition of anti-oxidant in the release medium were used to prevent degradation of naltrexone during release testing at "real-time" (37°C) and "accelerated" (45°C), respectively. The USP apparatus 4 method was more reproducible than the sample-and-separate method. In addition, the accelerated release profile obtained using USP apparatus 4 had a shortened release duration (within seven days), and good correlation with the "real-time" release profile. Lastly, the discriminatory ability of the developed accelerated release method was assessed using compositionally equivalent naltrexone microspheres with different release characteristics. The developed accelerated USP apparatus 4 release method was able to detect differences in the release characteristics of the prepared naltrexone microspheres. Moreover, a linear correlation was observed between the "real-time" and accelerated release profiles of all the formulations investigated, suggesting that the release mechanism(s) may be similar under both conditions. These results indicate that the developed accelerated USP apparatus 4 method has the potential to be an appropriate fast quality control tool for long-acting naltrexone PLGA microspheres.

    Naltrexone provides excellent opioid blockade, but its clinical utility is limited because opioid-dependent patients typically refuse it. An injectable suspension of naltrexone for extended release (XR-NTX) was recently approved by the FDA for treatment of opioid dependence. XR-NTX treatment may require concurrent behavioral intervention to maximize adherence and effectiveness, thus we sought to evaluate employment-based reinforcement as a method of improving adherence to XR-NTX in opiate dependent adults. Opioid-dependent adults (n=38) were detoxified and inducted onto oral naltrexone, then randomly assigned to contingency or prescription conditions. Participants received up to six doses of XR-NTX at four-week intervals. All participants could earn vouchers for attendance and performance at a therapeutic workplace. Contingency participants were required to accept XR-NTX injections to access the workplace and earn vouchers. Prescription participants could earn vouchers independent of their acceptance of XR-NTX injections. Contingency participants accepted significantly more naltrexone injections than prescription participants (87% versus 52%, p=.002), and were more likely to accept all injections (74% versus 26%, p=.004). Participants in the two conditions provided similar percentages of samples negative for opiates (72% versus 65%) and for cocaine (58% versus 54%). Opiate positivity was significantly more likely when samples were also cocaine positive, independent of naltrexone blockade (p=.002). Long-term adherence to XR-NTX in unemployed opiate dependent adults is low under usual care conditions. Employment-based reinforcement can maintain adherence to XR-NTX. Ongoing cocaine use appears to interfere with the clinical effectiveness of XR-NTX on opiate use. Copyright © 2011 Elsevier Ireland Ltd. All rights reserved.

    Given that cannabis use is increasing in the United States, pharmacological treatment options to treat cannabis use disorder are needed. Opioid antagonists modulate cannabinoid effects and may offer a potential approach to reducing cannabis use. In this double-blind, placebo-controlled human laboratory study, we assessed the effects of naltrexone maintenance on the reinforcing, subjective, psychomotor, and cardiovascular effects of active and inactive cannabis. Nontreatment-seeking, daily cannabis smokers were randomized to receive naltrexone (50 mg: n=18 M and 5 F) or placebo (0 mg; n=26 M and 2 F) capsules for 16 days. Before, during, and after medication maintenance, participants completed 10 laboratory sessions over 4–6 weeks, assessing cannabis' behavioral and cardiovascular effects. Medication compliance was verified by observed capsule administration, plasma naltrexone, and urinary riboflavin. Relative to placebo, maintenance on naltrexone significantly reduced both active cannabis self-administration and its positive subjective effects (‘good effect'). Participants in the placebo group had 7.6 times (95% CI: 1.1–51.8) the odds of self-administering active cannabis compared with the naltrexone group. This attenuation of reinforcing and positive subjective effects also influenced cannabis use in the natural ecology. Naltrexone had intrinsic effects: decreasing ratings of friendliness, food intake, and systolic blood pressure, and increasing spontaneous reports of stomach upset and headache, yet dropout rates were comparable between groups. In summary, we show for the first time that maintenance on naltrexone decreased cannabis self-administration and ratings of ‘good effect' in nontreatment-seeking daily cannabis smokers. Clinical studies in patients motivated to reduce their cannabis use are warranted to evaluate naltrexone's efficacy as a treatment for cannabis use disorder. PMID:25881117

    The purpose of this study was to determine if non-specific COX inhibition could extend pore lifetime in hairless guinea pigs following microneedle treatment. Hairless guinea pigs were treated with microneedle arrays ± daily application of Solaraze® gel (3% diclofenac sodium (non-specific COX inhibitor) and 2.5% hyaluronic acid); transepidermal water loss was utilized to evaluate pore lifetime. To examine the permeation of naltrexone, additional guinea pigs were treated with microneedles ± daily Solaraze® gel followed by application of a 16% transdermal naltrexone patch; pharmacokinetic analysis of plasma naltrexone levels was performed. Histological analysis was employed to visualize morphological changes following microneedle and Solaraze® treatment. Animals treated with microneedles + Solaraze® displayed extended pore lifetime (determined by transepidermal water loss measurements) for up to 7 days. Enhanced naltrexone permeation was also observed for an extended amount of time in animals treated with microneedles + Solaraze®. No morphological changes resulting from microneedle treatment or COX inhibition were noted. Non-specific COX inhibition is an effective means of extending pore lifetime following microneedle treatment in hairless guinea pigs. This may have clinical implications for extending transdermal patch wear time and therefore increasing patient compliance with therapy.

    The effects of a pharmacological blockade of the mu opiate receptors on the manifestation of tonic-clonic seizures were investigated in freely moving animals. 4-aminopyridine, a specific blocker of the neuronal K+ channels was used to produce generalized convulsions. After pretreatment of adult rats with 1 mg/kg naltrexone HCl, 3, 5, 7, 9, 14 mg/kg 4-aminopyridine was injected intraperitoneally, and the latencies of the symptoms generated by 4-aminopyridine were measured. Naltrexone HCl decreased these latencies and enhanced the seizures significantly. The experiments provided further evidence for the existence of a tonic anticonvulsant opioid system in the brain.

    Crohn's disease is a relapsing inflammatory condition afflicting the digestive tract. Drugs used for treatment of Crohn's disease may be associated with serious side effects. Endogenous opioid peptides modulate inflammatory cytokine production. Opioid antagonists have been shown to play a role in healing and repair of tissues. This work was designed to detect the possible beneficial effects of opioid antagonist naltrexone in indomethacin-induced Crohn's disease in rats. Enteritis was induced in male albino rats by two subcutaneous injection of indomethacin in a dose of 7.5mg/kg 24h apart started on day one. Salfasalazine, naltrexone and their combination were administered orally from day one of induction of enteritis to day 10. Disease activity index, serum levels of C-reactive protein and tumor necrosis factor-α, macroscopic and microscopic pathological scores and in vitro motility studies were evaluated. Induction of enteritis resulted in significant increase of disease activity index, significant elevation of serum levels of C-reactive protein and tumor necrosis factor-α, significant deterioration of pathological scores and significant increase in the mean contractility response of the isolated ileal segments compared with normal untreated rats. Treatment with sulfasalazine, low dose of natrexone or their combination resulted in significant improvement of all measured parameters compared with enteritis group. The current finding could provide new interesting opportunity for developing new therapeutic approaches for treatment of Crohn's disease. Use of naltrexone, especially in small dose, has little side effects making it of interest for treatment of Crohn's disease. Also, it provides the possibility of reduced doses of other drugs if it is used as combined therapy. Copyright © 2016 Elsevier Ltd. All rights reserved.

    The present study utilized a newly developed quantitative immunohistochemical assay to measure changes in {mu} opioid receptor abundance following chronic administration of the opioid receptor antagonist naltrexone. These data were compared with those obtained from {mu} receptor radioligand binding on adjacent tissue sections, in order to determine whether the characteristic antagonist-induced increase in radioligand binding is due to an increase in the total number of {mu} receptors and/or to an increase in the proportion of receptors that are in an active binding conformation in the absence of a change in the total number of receptors. Adult male Sprague-Dawley rats were administered naltrexone, 7-8 mg/kg per day, or saline continuously for seven days by osmotic minipumps, after which time their brains were processed for immunohistochemistry and receptor autoradiography on adjacent fresh frozen tissue sections. Semiquantitative immunohistochemistry was performed using a radiolabelled secondary antibody for autoradiographic determination and a set of radioactive standards. Results demonstrate an overall concordance between the distribution of {mu} opioid receptors as measured by the two different methods with a few exceptions. Following naltrexone administration, {mu} receptor immunoreactivity was significantly higher in the amygdala, thalamus, hippocampus, and interpeduncular nucleus as compared with the saline-treated control animals.

Following naltrexone administration, μ receptor immunoreactivity was significantly higher in the amygdala, thalamus, hippocampus, and interpeduncular nucleus as compared with the saline-treated control animals. [ 3 H]D-Ala 2 ,N-Me-Phe 4 ,Gly-ol 5 -enkephalin binding to μ opioid receptors was significantly higher in the globus pallidus, amygdala, thalamus, hypothalamus, hippocampus, substantia nigra, ventral tegmental area, central gray, and interpeduncular nucleus of the naltrexone-treated rats.These findings indicate that in some brain regions chronic naltrexone exposure increases the total number of μ opioid receptors, while in other regions there is an increase in the percent of active receptors without an observable change in the total number

    Male rats allowed to copulate until reaching sexual exhaustion exhibit a long-lasting sexual behavior inhibition (around 72 h) that can be reversed by systemic opioid receptor antagonist administration. Copulation activates the mesolimbic dopaminergic system (MLS) and promotes endogenous opioid release. In addition, endogenous opioids, acting at the ventral tegmental area (VTA), modulate the activity of the MLS. We hypothesized that endogenous opioids participate in the sexual exhaustion phenomenon by interacting with VTA opioid receptors and consequently, its reversal by opioid antagonists could be exerted at those receptors. In this study we determined the effects of intra-VTA infusion of different doses of the non-specific opioid receptor antagonist naltrexone (0.1-1.0 μg/rat) on the already established sexual behavior inhibition of sexually exhausted male rats. To elucidate the possible involvement of VTA δ-opioid receptors in the naltrexone-mediated reversal of sexual exhaustion, the effects of different doses of the selective δ-opioid receptor antagonist, naltrindole (0.03-1.0 μg/rat) were also tested. Results showed that intra-VTA injection of 0.3 μg naltrexone reversed the sexual inhibition of sexually exhausted rats, evidenced by an increased percentage of animals capable of showing two successive ejaculations. Intra-VTA infused naltrindole did not reverse sexual exhaustion at any dose. It is concluded that the MLS is involved in the reversal of sexual exhaustion induced by systemic naltrexone, and that μ-, but not δ-opioid receptors participate in this effect. Intra-VTA naltrexone infusion to sexually experienced male rats had an inhibitory effect on sexual activity. The opposite effects of intra-VTA naltrexone on male rat sexual behavior expression of sexually experienced and sexually exhausted rats is discussed. Copyright © 2013 Elsevier B.V.

    To investigate the effects of the long-acting opiate antagonist naltrexone on spontaneous human eating behavior, eight moderately obese male paid volunteers were housed in a hospital metabolic unit for 28 days and offered palatable foods ad lib by a platter service method. Under double-blind conditions, equally divided doses of 100, 200 and 300 mg naltrexone, or an acetaminophen placebo, were administered twice daily in tablet form for 3-day periods each, according to a Latin Square design. The doses of naltrexone resulted in decreases of daily caloric intake from placebo level, but these reductions were neither statistically significant nor dose-related. When the averaged effects of the doses were compared to placebo, five subjects showed intake reductions but the overall intake reduction of 301.5 +/- 198.1 kcal/day (mean +/- SEM) was not statistically significant. Naltrexone administration failed to selectively alter intakes of individual meals and snacks or macronutrient consumption patterns. During active drug periods, subjects lost 0.62 +/- 0.22 lb over 3 days, while during the placebo period, subjects gained 0.46 +/- 0.68 lb. However, there was no reliable change of basal metabolic rate as a function of naltrexone administration. The present results, which indicate that naltrexone administration is relatively ineffective in reducing food intake and inducing body weight loss in obese humans, are thus in contrast with reports that administration of opiate antagonist agents promote significant reductions of food intake and attenuations of body weight gain in experimental animals.

    Heavy drinking among young adults is a serious public health problem. Naltrexone, an opioid antagonist, has been shown to reduce drinking in young adults compared to placebo and can be taken on a targeted (i.e., as needed) basis. Understanding risk factors for drinking and naltrexone effects within-person in young adults may help to optimize the use of targeted naltrexone. The current study was a secondary analysis of daily diary data from 127 (n = 40 female) young adults (age 18-25) enrolled in a double-blind clinical trial of daily (25 mg) plus targeted (25 mg) naltrexone versus placebo. Hierarchical linear models were used to examine the effects of daily affect, urge, and taking targeted medication on same-day risk of drinking to intoxication (defined as estimated blood-alcohol-concentration, BAC ≥ .08 g%). Results indicated urge significantly mediated within-person positive affect-drinking relations on a daily level. Specifically, positive affect was associated with greater urge to drink, which in turn was associated with greater odds of BAC ≥ .08 g%. Furthermore, days of greater positive affect and urge were associated with taking a targeted dose of medication, which reduced the likelihood of intoxication by nearly 23% in the naltrexone group compared to placebo. Gender and family history of alcohol dependence were examined as moderators of these daily level effects. These results provide further evidence of naltrexone's ability to reduce alcohol consumption in young adults and identify potential within-person risk processes related to heavy drinking that could inform alcohol-related interventions for this population.

    Background and Objective Although transcatheter closure of perimembranous ventricular septal defect is emerging as an accepted, viable alternative, conduction disturbances still remain a major concern. Although steroid treatment has shown encouraging results with complete recovery, efficacy of prophylactic use of steroids is still speculative. We aim to study the mid-term outcome of perimembranous ventricular septal defect closure in children who received prophylactic oral steroids. Materials and methods A prospective study was designed and antegrade device closure was attempted in eligible children who met the following inclusion criteria: age 3-18 years and weight >10 kg, defect diameter ⩽12 mm, and symptomatic, haemodynamic changes or history of infective endocarditis. Prophylactic steroid protocol consisted of 2 weeks oral prednisolone (1 mg/kg/day) initiated immediately after the procedure, and in the event of bradyarrhythmia it was escalated to 2 mg/kg. Patients were regularly followed-up at 1, 6, and 12 months and then annually. Patients with post-procedure heart block underwent Holter monitoring after a minimum of 1 year interval. Between May, 2007 and August, 2012, successful device closure was accomplished in 290/297 patients. Mean age and weight were 9±3.12 years and 21±8.27 kg, respectively. The defect measured 5±1.38 mm on echocardiography. Mean fluoroscopy time was 12.98±8.64 minutes. Eight patients with major complications included one each with device embolisation, haemolysis, severe aortic regurgitation, and five with bradyarrhythmias, including complete atrioventricular block in three, Mobitz II in one, and bifascicular block in one. Patients with complete atrioventricular block responded to high-dose steroid and temporary pacemaker. Minor complications included post-procedure heart block (n=22) and blood loss (n=2). At 18.23±13.15 months follow-up, 8/27 (five major, 22 minor) with arrhythmia had persistent post-procedure heart block of no

    The opioid antagonist naltrexone, combined with cognitive behavioural therapy (CBT), has proven efficacious for patients with alcohol dependence, but studies examining how this treatment works in a naturalistic treatment setting are lacking. This study examined predictors of the outcome of targeted naltrexone and CBT in a real-life outpatient setting. Participants were 315 patients who attended a treatment program providing CBT combined with the targeted use of naltrexone. Mixture models for estimating developmental trajectories were used to examine change in patients' alcohol consumption and symptoms of alcohol craving from treatment entry until the end of the treatment (20 weeks) or dropout. Predictors of treatment outcome were examined with analyses of multinomial logistic regression. Minimal exclusion criteria were applied to enhance the generalizability of the findings. Regular drinking pattern, having no history of previous treatments, and high-risk alcohol consumption level before the treatment were associated with less change in alcohol use during the treatment. The patients with low-risk alcohol consumption level before the treatment had the most rapid reduction in alcohol craving. Patients who drank more alcohol during the treatment had lower adherence with naltrexone. Medication non-adherence is a major barrier to naltrexone's effectiveness in a real-life treatment setting. Patients with more severe alcohol problems may need more intensive treatment for achieving better treatment outcome in real-word treatment settings.

    Excess consumption of palatable food has been shown to affect reward-related brain regions, and pharmaceutical treatments for drug addiction may also be effective in treating overeating of such foods. The GABA-B agonist baclofen and opioid antagonist naltrexone have both been used to treat addiction, and have been shown to suppress intake of certain foods. The combination of these drugs has shown to be more effective in reducing alcohol consumption than either drug alone. The present study assessed the effects of naltrexone and baclofen, alone and in combination, on intake of foods comprised of various macronutrients. Male Sprague-Dawley rats were given 12-hr daily access to chow and a fat emulsion, sugar-fat emulsion, or a sugar solution for 21 days. Rats were then administered (intraperitoneal) baclofen-naltrexone combinations (0.1 mg/kg naltrexone and 1.0 mg/kg baclofen, 1.0 mg/kg naltrexone and 1.8 mg/kg baclofen), and naltrexone (0.1, 1.0 mg/kg) and baclofen (1.0, 1.8 mg/kg) alone. The high dose of the baclofen-naltrexone combination reduced palatable food intake in both the fat and sugar-fat groups compared with vehicle, without affecting chow consumption in these groups. Naltrexone showed little significant effects on intake of either palatable food or chow. Baclofen also reduced palatable food intake in the fat and fat-sugar groups, but differences were only noted between the low and high dose. The combination of baclofen and naltrexone may be a useful tool in selectively targeting the consumption of high-fat and sugar- and fat-rich foods.

    To aid public health policymaking, we studied the cost-effectiveness of buprenorphine, naltrexone, and placebo interventions for heroin dependence in Malaysia. We estimated the cost-effectiveness ratios of three treatments for heroin dependence. We used a microcosting methodology to determine fixed, variable, and societal costs of each intervention. Cost data were collected from investigators, staff, and project records on the number and type of resources used and unit costs; societal costs for participants' time were estimated using Malaysia's minimum wage. Costs were estimated from a provider and societal perspective and reported in 2004 US dollars. Muar, Malaysia. 126 patients enrolled in a randomized, double-blind, placebo-controlled clinical trial in Malaysia (2003-2005) receiving counseling and buprenorphine, naltrexone, or placebo for treatment of heroin dependence. Primary outcome measures included days in treatment, maximum consecutive days of heroin abstinence, days to first heroin use, and days to heroin relapse. Secondary outcome measures included treatment retention, injection drug use, illicit opiate use, AIDS Risk Inventory total score, and drug risk and sex risk subscores. Buprenorphine was more effective and more costly than naltrexone for all primary and most secondary outcomes. Incremental cost-effectiveness ratios were below $50 for primary outcomes, mostly below $350 for secondary outcomes. Naltrexone was dominated by placebo for all secondary outcomes at almost all endpoints. Incremental treatment costs were driven mainly by medication costs, especially the price of buprenorphine. Buprenorphine appears to be a cost-effective alternative to naltrexone that might enhance economic productivity and reduce drug use over a longer term.

    Significant preclinical evidence exists for a synergistic interaction between the opioid and the serotonin systems in determining alcohol consumption. Naltrexone, an opiate receptor antagonist, is approved for the treatment of alcohol dependence. This double-blind placebo-controlled study examined whether the efficacy of naltrexone would be augmented by concurrent treatment with sertraline, a selective serotonin receptor uptake inhibitor (SSRI).

    Compliance with medication in pharmacotherapy trials of alcoholism has been shown to be equal to, or more, important than in other areas of medicine. Research has suggested that naltrexone's effectiveness can be greatly influenced by the compliance of participants in clinical trials. Presently, we compare 2 compliance measurement methods [urine riboflavin and medication event monitoring system (MEMS)] used simultaneously to evaluate naltrexone's efficacy and the impact of compliance on the size of observable treatment effects. One hundred and thirty-seven of 160 randomized alcoholic patients completed 12-weeks (84 days) of naltrexone or placebo and cognitive behavioral therapy (CBT) or motivational enhancement therapy (MET). Urine riboflavin was determined during study weeks 2, 6, and 12. The MEMS provided a detailed computerized record of when a participant opened their medication bottle throughout the trial. Baseline predictors of MEMS (80% openings) and urine riboflavin (>or=1,500 ng/mL by fluorimetry) compliance were examined. The effects of the treatments in the compliant participants defined by one, the other, or both methods were compared and contrasted with a previously reported intent-to-treat analysis where compliance was not taken into account. Age was predictive of compliance. 105 participants were deemed compliant via urine riboflavin criteria, 87 via MEMS, and 77 when both criteria were met, with no significant differences between treatment groups. The most compliant participants showed a significant medication by therapy interaction. Those treated with naltrexone/CBT showed more abstinence days (pcompliance measurement methods. Compliance measurement does appear to influence the evaluation of the efficacy of naltrexone within the context of CBT. Treatment effect sizes approximately doubled in the most compliant individuals. Measuring compliance by either of 2 distinct methods provides approximately similar results. As compliance with naltrexone

    Pregnant women with opioid use disorder can be treated with methadone, buprenorphine, or naltrexone to reduce opioid use and improve retention to treatment. In this review, we compare the pregnancy outcomes of methadone, buprenorphine, and naltrexone in clinical trials and discuss the potential behavioral and developmental effects of these agents seen in offspring in animal studies. Important clinical considerations in the management of opioid use disorder in pregnant women and their infants are also discussed. Outside of pregnancy, buprenorphine is used in combination with naloxone to reduce opioid abuse and diversion. During pregnancy, however, the use of buprenorphine as a single agent is preferred to prevent prenatal naloxone exposure. Both methadone and buprenorphine are widely used to treat opioid use disorder; however, compared with methadone, buprenorphine is associated with shorter treatment duration, less medication needed to treat neonatal abstinence syndrome (NAS) symptoms, and shorter hospitalizations for neonates. Despite being the standard of care, medication-assisted treatment with methadone or buprenorphine is still underused, making it apparent that more options are necessary. Naltrexone is not a first-line treatment primarily because both detoxification and an opioid-free period are required. More research is needed to determine naltrexone safety and benefits in pregnant women. Animal studies suggest that changes in pain sensitivity, developmental processes, and behavioral responses may occur in children born to mothers receiving methadone, buprenorphine, or naltrexone and is an area that warrants future studies. © 2017 Pharmacotherapy Publications, Inc.

    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.

    Complex Regional Pain Syndrome (CRPS) is a neuropathic pain syndrome, which involves glial activation and central sensitization in the central nervous system. Here, we describe positive outcomes of two CRPS patients, after they were treated with low-dose naltrexone (a glial attenuator), in combination with other CRPS therapies. Prominent CRPS symptoms remitted in these two patients, including dystonic spasms and fixed dystonia (respectively), following treatment with low-dose naltrexone (LDN). LDN, which is known to antagonize the Toll-like Receptor 4 pathway and attenuate activated microglia, was utilized in these patients after conventional CRPS pharmacotherapy failed to suppress their recalcitrant CRPS symptoms.

    Antagonism of opioid systems (e.g., with naltrexone) has been explored as an anti-obesity strategy, and is particularly effective when co-administered with dual inhibitors of dopamine and norepinephrine reuptake (e.g., bupropion). Previously, we demonstrated that amylin enhances the food intake lowering and weight loss effects of neurohormonal (e.g., leptin, cholecystokinin, melanocortins) and small molecule (e.g., phentermine, sibutramine) agents. Here, we sought to characterize the interaction of amylin with naltrexone/bupropion on energy balance. Wild-type and amylin knockout mice were similarly responsive to the food intake lowering effects of either naltrexone (1mg/kg, subcutaneous) or bupropion (50mg/kg, subcutaneous) suggesting that they act independently of amylinergic systems and could interact additively when given in combination with amylin. To test this, diet-induced obese rats were treated (for 11 days) with vehicle, rat amylin (50 μg/kg/d, infused subcutaneously), naltrexone/bupropion (1 and 20mg/kg, respectively by twice daily subcutaneous injection) or their combination. We found that amylin+naltrexone/bupropion combination therapy exerted additive effects to reduce cumulative food intake, body weight and fat mass. In a separate study, the effects of amylin and naltrexone/bupropion administered at the same doses (for 14 days) were compared to a pair-fed group. Although the combination and pair-fed groups lost a similar amount of body weight, rats treated with the combination lost 68% more fat and better maintained their lean mass. These findings support the strategy of combined amylin agonism with opioid and catecholaminergic signaling systems for the treatment of obesity. Copyright © 2012 Elsevier B.V. All rights reserved.

    The role of endogenous opioid systems in preweaning development after intrauterine exposure to X-irradiation or ethylnitrosourea (ENU) was explored in rats using naltrexone, a potent antagonist of beta-endorphin. After daily s.c. injections of 50 mg/kg naltrexone only the prenatally untreated controls had body weights increased by 11% from control level on day 28 (weaning). In the X-irradiated as well as the ENU-treated pups no significant effects of naltrexone on body weight gain were observed. However, brain weight increased in all animals under the influence of naltrexone, irrespective of prenatal treatment or the severity of brain lesions: 9.5% above control values in untreated offspring and 14% after X-irradiation (1 Gy) on gestation day 14. The brain weight of ENU-treated rats (50 mg/kg on gest. day 14) was 13% higher after postnatal naltrexone application than that of their postnatally untreated counterparts. ENU (80 mg/kg) effects on the brain when given on gestation day 18 were ameliorated to 9.2% by naltrexone in the weaning period. Naltrexone significantly increased the thymus weight in controls. Prenatally treated animals also showed an increased thymus weight at weaning, presumably due to compensatory growth. In these cases naltrexone revealed a suppressive effect on the thymus, whereas spleen weight was apparently not influenced by naltrexone treatment. These results provide compelling evidence that endogenous opioid systems play a crucial role not only in normal development, but also in reparative growth events of the brain after prenatal injuries. The thymus, predominantly containing T-lymphocytes, seems to represent another sensitive system which is regulated under the influence of opioids

    Objective was to evaluate the therapeutic and prophylactic effectiveness of oral zinc sulfate in recurrent aphthous stomatitis RAS in comparison with dapsone. A double-blind placebo controlled study, conducted in the Department of Dermatology, Baghdad Teaching Hospitals, Baghdad, Iraq between May 2005 and October 2006, in which 45 patents with RAS were recruited and divided into 3 equal groups: group A on zinc sulfate 150 mg twice daily, group B on dapsone 50 mg twice daily and group C on glucose 250 mg as placebo. The drugs were prepared in identical capsules and patents were instructed to take the capsules twice daily after meals in a double blind manner. Assessment of each patient was carried out by the Oral Clinical Manifestation Index OCMI and the diameter of the ulcers at day 0, day 4 and the second, fourth, sixth, eighth, tenth and twelfth weeks of the therapy. Forty-five patients were included in the study 25 males and 20 females and their ages ranged between 16-45 years mean +/-SD 31.24+/-8.14. In group A, the mean of OCMI and diameters of the ulcers improved, with a p=0.0001 for OCMI, and 0.0001 for the diameter for ulcers at the end of the twelfth week of therapy, which was statistically significant. Group B also showed significant improvement, however, the action was lower and slower p=0.0001 for OCMI and 0.001 for the diameter for ulcers. Group C revealed slight non-significant improvement p=0.028 for OCMI and 0.034 for the diameter of ulcers. In the sixth week of therapy, zinc sulfate was more effective than dapsone in reducing in reducing the reducing the OCMI of the ulcers p=0.007. The present study showed that both zinc sulfate and dapsone had significant therapeutic and prophylactic affects in controlling RAS, however, zinc sulfate had much more rapid and sustained action.

    Full Text Available Alcohol use disorder (AUD is a worldwide public health problem and a polygenetic disorder displaying substantial individual variation. This work aimed to study individual differences in behavior and its association to voluntary alcohol intake and subsequent response to naltrexone in a seamless heterogenic group of animals. Thus, by this approach the aim was to more accurately recapitulate the existing heterogeneity within the human population. Male Wistar rats from three different suppliers (Harlan Laboratories B.V., RccHanTM:WI; Taconic Farms A/S, HanTac:WH; and Charles River GmbH, Crl:WI were used to create a heterogenic group for studies of individual differences in behavior, associations to intermittent voluntary alcohol intake and subsequent response to naltrexone. The rats were tested in the open field prior to the Y-maze and then given voluntary intermittent access to alcohol or water in the home cage for six weeks, where after, naltrexone in three different doses or saline was administered in a Latin square design over four weeks and alcohol intake and preference was measured. However, supplier-dependent differences and concomitant skew subgroup formations, primarily in open field behavior and intermittent alcohol intake, resulted in a shifted focus to instead study voluntary alcohol intake and preference, and the ensuing response to naltrexone in Wistar rats from three different suppliers. The results showed that outbred Wistar rats are diverse with regard to voluntary alcohol intake and preference in a supplier-dependent manner; higher in RccHanTM:WI relative to HanTac:WH and Crl:WI. The results also revealed supplier-dependent differences in the effect of naltrexone that were dose- and time-dependent; evident differences in high-drinking RccHanTM:WI rats relative to HanTac:WH and Crl:WI rats. Overall these findings render RccHanTM:WI rats more suitable for studies of individual differences in voluntary alcohol intake and response to

    Background Extended-release naltrexone (XR-NTX), is an effective treatment for opioid use disorder but is rarely initiated in US prisons or with criminal justice populations. Mobile treatment for chronic diseases have been implemented in a variety of settings. Mobile treatment may provide an opportunity to expand outreach to parolees to surmount barriers to traditional clinic treatment. Methods Male and female prisoners (240) with pre-incarceration histories of opioid use disorder who are within one month of release from prison will be enrolled in this randomized clinical trial. Participants are randomized to one of two study arms: 1) [XR-NTX-OTx] One injection of long-acting naltrexone in prison, followed by 6 monthly injections post-release at a community opioid treatment program; or 2) [XR-NTX+ MMTx] One injection of long-acting naltrexone in prison followed by 6 monthly injections post-release at the patient's place of residence utilizing mobile medical treatment. The primary outcomes are: treatment adherence; opioid use; criminal activity; re-arrest; reincarceration; and HIV risk-behaviors. Results We describe the background and rationale for the study, its aims, hypotheses, and study design. Conclusions The use of long-acting injectable naltrexone may be a promising form of treatment for pre-release prisoners. Finally, as many individuals in the criminal justice system drop out of treatment, this study will assess whether treatment at their place of residence will improve adherence and positively affect treatment outcomes.

    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.

    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.

  14. The Safety and Efficacy of Low-Dose Naltrexone in the Management of Chronic Pain and Inflammation in Multiple Sclerosis, Fibromyalgia, Crohn's Disease, and Other Chronic Pain Disorders.

    Chronic inflammatory diseases are complex to treat and have an impact on a large number of patients. Due to the difficulty of treating these diseases and the great impact on quality of life, patients often seek off-label, complimentary, or alternative medicines to gain relief from symptoms. Low-dose naltrexone has been used off-label for treatment of pain and inflammation in multiple sclerosis, Crohn's disease, fibromyalgia, and other diseases. Naltrexone is a mu-opioid receptor antagonist indicated by the U.S. Food and Drug Administration for opioid and alcohol dependence. It is hypothesized that lower than standard doses of naltrexone inhibit cellular proliferation of T and B cells and block Toll-like receptor 4, resulting in an analgesic and antiinflammatory effect. It is the purpose of this review to examine the evidence of the safety, tolerability, and efficacy of low-dose naltrexone for use in chronic pain and inflammatory conditions. Currently, evidence supports the safety and tolerability of low-dose naltrexone in multiple sclerosis, fibromyalgia, and Crohn's disease. Fewer studies support the efficacy of low-dose naltrexone, with most of these focusing on subjective measures such as quality of life or self-reported pain. These studies do demonstrate that low-dose naltrexone has subjective benefits over placebo, but evidence for more objective measures is limited. However, further randomized controlled trials are needed to determine the efficacy of low-dose naltrexone due to insufficient evidence supporting its use in these disease states. This review provides practitioners with the extent of low-dose naltrexone evidence so that they can be cognizant of situations where it may not be the most appropriate therapy. © 2018 Pharmacotherapy Publications, Inc.

    Objective: The rates of obesity and cigarette smoking are much higher in patients with schizophrenia compared to the general population. This study was to examine whether naltrexone and bupropion combination treatment can help weight loss and smoking cessation in patients with schizophrenia. Methods: Obese male schizophrenia patients with current cigarette smoking were randomized to receive adjunctive naltrexone (25 mg/day) and bupropion (300 mg/day) combination or placebo for 24 weeks. Twenty-two patients were enrolled in the study, and 21 patients completed the study (11 in the treatment group, and 10 in the placebo group). Body weight, body mass index (BMI), fasting lipids, smoking urge, expired carbon monoxide (CO) level and cigarettes smoked per week were measured at baseline and week 24. Results: There was no significant difference between two groups in changes in weight, BMI, fasting lipids, or cigarette smoking measures ( p 's > 0.05) Conclusion: Naltrexone and bupropion combination treatment didn't show weight loss or smoking cessation effect in patients with schizophrenia in this pilot study.Implications for future studies were discussed.

    Pathological gambling (PG) is a relatively common and highly disabling impulse control disorder. A range of psychotherapeutic agents, including selective serotonin reuptake inhibitors, mood stabilizers, and opioid antagonists, has been shown to be effective in the treatment of PG. The use of selective serotonin reuptake inhibitors and opioid antagonists for PG is consistent with the observation that PG shares features of both the obsessive-compulsive spectrum disorders and addictive disorders. The aim of the study is to compare the effectiveness of sustained-release bupropion versus naltrexone in the treatment of PG. Thirty-six male pathological gamblers were enrolled in our study. A comprehensive psychiatric diagnostic evaluation was performed at baseline on all patients, and patients were screened for symptoms of gambling, depression, and anxiety using the South Oaks Gambling Screen, the Hamilton Depression Rating Scale, the Hamilton Anxiety Rating Scale, and the Clinical Global Impression-Severity Scale. In addition, the patients completed self-report questionnaires about their demographic status. Patients were randomized in 2 groups and received either naltrexone (n = 19) or sustained-release bupropion (n = 17) for 12 weeks in a parallel fashion. Treatment response was monitored using the Clinical Global Impression-Improvement Scale which was performed at weeks 2, 4, 8, and 12. Patients were also assessed for the presence of gambling behavior via an unstructured interview, which was also performed at weeks 2, 4, 6, 8, and 12. Raters were blind to the study treatment. The majority of patients responded well to the drug treatment. Twelve of 17 patients in the sustained-release bupropion group completed the 12-week study, and 13 of 19 naltrexone patients completed the study. Nine (75%) of the 12 completers were rated as full responders in the sustained-release bupropion group versus 10 (76%) of 12 in the naltrexone group. Three (25%) of 12 completers in the

    Pain in neonates is associated with short and long-term adverse outcomes. Data demonstrated that long-term consequences of untreated pain are linked to the plasticity of the neonate's brain. Sucrose is effective and safe for reducing painful procedures from single events. However, the mechanism of sucrose-induced analgesia is not fully understood. The role of the opioid system in this analgesia using the opioid receptor antagonist Naltrexone was investigated, plus the long-term effects on learning and memory formation during adulthood. Pain was induced in rat pups via needle pricks of the paws. Sucrose solution and/or naltrexone were administered before the pricks. All treatments started on day one of birth and continued for two weeks. At the end of 8weeks, behavioral studies were conducted to test spatial learning and memory using radial arm water maze (RAWM), and pain threshold via foot-withdrawal response to a hot plate. The hippocampus was dissected; levels of brain derived neurotrophic factor (BDNF) and endorphins were assessed using ELISA. Acute repetitive neonatal pain increased pain sensitivity later in life, while naltrexone with sucrose decreased pain sensitivity. Naltrexone and/or sucrose prevented neonatal pain induced impairment of long-term memory, while neonatal pain decreased levels of BDNF in the hippocampus; this decrease was averted by sucrose and naltrexone. Sucrose with naltrexone significantly increased β-endorphin levels in noxiously stimulated rats. In conclusion, naltrexone and sucrose can reverse increased pain sensitivity and impaired long-term memory induced by acute repetitive neonatal pain probably by normalizing BDNF expression and increasing β-endorphin levels.

    Long acting intramuscular (IM) naltrexone is an effective treatment for opioid use disorder (OUD), but rates and correlates of its use have not been studied. National administrative from the Veterans Health Administration (VHA) from Fiscal Year 2012 identified only 16 VHA facilities that prescribed IM naltrexone to 5 or more veterans diagnosed with OUD. Data from these facilities were used to identify sociodemographic, diagnostic, and service use characteristics, including use of psychotropic medication, that were characteristic of veterans who filled prescriptions for IM naltrexone. This was in comparison to users of opiate agonist treatments (methadone or buprenorphine) or veterans with no pharmacologic treatment for OUD. Comparisons were made using both bi-variate analyses and multivariable logistic regression. Only 179 of 16,402 veterans with OUD (1%) at these 16 facilities filled a prescription for IM naltrexone and only 256 of 99,394 (0.26%) nationally. These veterans were characterized by past homelessness, co-morbid alcohol use disorder, multiple psychiatric disorders, and a greater likelihood of psychiatric hospitalization, as well as mental health outpatient and antidepressant medication use. IM naltrexone is rarely used for OUD and is primarily used for patients with multiple co-morbidities, especially alcohol use disorder and serious mental illness. The use of this treatment illustrates many of the principles identified by the emerging focus on multi-morbidity as a critical feature of clinical practice. Copyright © 2017.

    The purpose of this multicentre study was to determine the incidence of oral candidiasis in patients treated with topical steroids for oral lichen planus (OLP) and to determine whether the application of a concurrent antifungal therapy prevented the development of an oral candidiasis in these patients. Records of 315 patients with OLP seen at four Oral Medicine practices treated for at least 2 weeks with steroids with and without the use of an antifungal regimen were retrospectively reviewed. The overall incidence of oral fungal infection in those treated with steroid therapy for OLP was 13.6%. There was no statistically significant difference in the rate of oral candidiasis development in those treated with an antifungal regimen vs those not treated prophylactically (14.3% vs 12.6%) (P = 0.68). Despite the use of various regimens, none of the preventive antifungal strategies used in this study resulted in a significant difference in the rate of development of an oral candidiasis in patients with OLP treated with steroids. © 2015 John Wiley & Sons A/S.

    This study investigated predictors of dropout in an outpatient treatment program for problem drinking that included individual cognitive-behavioral therapy combined with naltrexone. Specifically, we investigated whether sociodemographic factors, severity of alcohol dependence, history of problem drinking, or intensity of alcohol craving assessed at the beginning of the treatment predicted dropout from an outpatient program among a sample of 372 patients (65% male). We also investigated whether the effectiveness of the treatment (the change in alcohol consumption and symptoms of alcohol craving) or adherence to naltrexone was related to dropout. Predictors of dropout were investigated using an analysis of covariance with the number of attended treatment sessions as an independent variable. Our results demonstrated that the treatment entry factors predictive of dropout were younger age, lower severity of alcohol dependence, better ability to resist and control alcohol use, and lower obsession with alcohol. In addition, those who dropped out were more likely to begin the program by abstaining from alcohol and had lower adherence to naltrexone use than those who completed the program. The length of stay for treatment was not related to change in alcohol consumption. Patients with less severe alcohol-related problems may lack motivation for treatment, specifically cognitive-behavioral therapy and naltrexone. These patients may benefit more from less intensive treatments.

    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)

  3. Effects of naltrexone on pain sensitivity and mood in fibromyalgia: no evidence for endogenous opioid pathophysiology.

    Directory of Open Access Journals (Sweden)

    Jarred W Younger

    Full Text Available The pathophysiological mechanisms underlying fibromyalgia are still unknown, although some evidence points to endogenous opioid dysfunction. We examined how endogenous opioid antagonism affects pain and mood for women with and without fibromyalgia. Ten women with fibromyalgia and ten age- and gender-matched, healthy controls each attended two laboratory sessions. Each participant received naltrexone (50mg at one session, and placebo at the other session, in a randomized and double-blind fashion. Participants were tested for changes in sensitivity to heat, cold, and mechanical pain. Additionally, we collected measures of mood and opioid withdrawal symptoms during the laboratory sessions and at home the night following each session. At baseline, the fibromyalgia group exhibited more somatic complaints, greater sensory sensitivity, more opioid withdrawal somatic symptoms, and lower mechanical and cold pain-tolerance than did the healthy control group. Neither group experienced changes in pain sensitivity due to naltrexone administration. Naltrexone did not differentially affect self-reported withdrawal symptoms, or mood, in the fibromyalgia and control groups. Consistent with prior research, there was no evidence found for abnormal endogenous opioid activity in women with fibromyalgia.

    -reported in the included studies. We did not find any studies comparing homeopathic remedies with either a placebo or no treatment. There was insufficient evidence to support the use of prophylactic oral methylergometrine given after delivery of the placenta for the prevention of PPH. Additionally, the effectiveness of prophylactic use of herbal medicine or homeopathic remedies for PPH is still unclear as we could not find any clear evidence. Trials to assess the effectiveness of herbal medicines and homeopathic remedies in preventing PPH are warranted.

    Purpose Obese individuals vary in their experience of food cravings and tendency to engage in reward-driven eating, both of which can be modulated by the neural reward system rather than physiological hunger. We examined two predictions in a sample of obese women: (1) whether opioidergic blockade reduced food-craving intensity, and (2) whether opioidergic blockade reduced an association between food-craving intensity and reward-driven eating, which is a trait-like index of three factors (lack of control over eating, lack of satiation, preoccupation with food). Methods Forty-four obese, pre-menopausal women completed the Reward-based Eating Drive (RED) scale at study start and daily food-craving intensity on 5 days on which they ingested either a pill-placebo (2 days), a 25mg naltrexone dose (1 day), or a standard 50mg naltrexone dose (2 days). Results Craving intensity was similar under naltrexone and placebo doses. The association between food-craving intensity and reward-driven eating significantly differed between placebo and 50mg naltrexone doses. Reward-driven eating and craving intensity were significantly positively associated under both placebo doses. As predicted, opioidergic blockade (for both doses 25mg and 50mg naltrexone) reduced this positive association between reward-driven eating and craving intensity to non-significance. Conclusions Opioidergic blockade did not reduce craving intensity; however, blockade reduced an association between trait-like reward-driven eating and daily food-craving intensity, and may help identify an important endophenotype within obesity.

    This study investigated whether subgroups of alcohol-dependent patients responded differently to naltrexone versus placebo in the NIAAA COMBINE study. In particular, the A versus B and the Early Onset versus Late Onset typologies were examined. Relative to Type A alcoholics, Type B alcoholics are characterized by greater severity, earlier onset, stronger family history, more childhood risk factors (e.g., conduct disorder), and greater frequency of comorbid psychiatric and substance use disorders. COMBINE study participants were categorized as Type A or Type B using k-means cluster analysis and variables from 5 domains that have been shown to replicate the original Babor typology efficiently. Early Onset was defined as alcohol dependence beginning before age 25. For the planned analyses, the sample was reduced to the 618 participants receiving naltrexone alone or placebo, either with medical management (MM) alone or with MM plus the Combined Behavioral Intervention (CBI). The a priori primary outcome was percent heavy drinking days during treatment in the groups receiving MM without CBI. Among those receiving MM without CBI, Type A alcoholics had better drinking outcomes with naltrexone than placebo, whereas medication condition did not influence outcomes significantly in the Type Bs. Age of onset was not significantly related to outcome. For those receiving CBI, no significant effects were found for either typology. In this sample, the beneficial effects of opioid antagonism were limited to Type A alcoholics receiving treatment in a MM model. Future studies should investigate the relationship between clinically relevant genotypes, phenotypes such as typologies, and treatment response. More work is also needed to develop practical algorithms for phenotypic assignment.

    Full Text Available Acute radiation dermatitis is a frequent adverse effect in patients with breast cancer undergoing radiotherapy, but there are only a small number of studies providing evidence-based interventions for this clinical condition. Adlay is a cereal crop that has been previously shown to have anti-inflammatory and antioxidant properties. In this study, we seek to evaluate the effectiveness of oral prophylactic treatment with adlay bran extract in reducing the risk of severe acute radiation dermatitis. A total of 110 patients with breast cancer undergoing radiotherapy were analyzed. Using a prospective, randomized, double-blind design, 73 patients received oral treatment with adlay bran extract and 37 patients received olive oil (placebo. Treatment was started at the beginning of radiation therapy and continued until the termination of radiation treatment. Our results showed that the occurrence of severe acute radiation dermatitis (RTOG grade 2 or higher was significantly lower in patients treated with oral adlay bran extract compared to placebo (45.2% versus 75.7%, adjusted odds ratio 0.24. No serious adverse effects from adlay bran treatment were noted. In conclusion, prophylactic oral treatment with adlay bran extract reduces the risk of severe acute radiation dermatitis and may have potential use in patients with breast cancer undergoing radiotherapy.

    Full Text Available Cardiovascular effects of opioid withdrawal have long been studied. It was reported that patients with underlying ischemic heart disease and atherosclerotic vessels may be complicated by a sudden physical and emotional stress due to withdrawal syndrome. But some other believes sudden increase in catecholamine level as a sympathetic overflow might effect on heart with and without underlying ischemia. In the current study, a patient on methadone maintenance therapy (MMT who experienced myocardial infarction (MI after taking naltrexone was described.

    Full Text Available Nephrotoxicity is a major side effect of cisplatin, a widely used chemotherapy agent. Morphine and other opioids are also used extensively in different types of cancer for the clinical management of pain associated with local or metastatic neoplastic lesions. In addition to its analgesic effects, morphine has also been reported to possess potential immunomodulatory and antioxidant properties. Herein, we investigated the effects of morphine in a rat model of cisplatin-induced nephrotoxicity. Following administration of a single dose of cisplatin (5 mg/kg, animals received intraperitoneal injections of morphine (5 mg/kg/day and/or naltrexone (20 mg/kg/day, an opioid antagonist, for 5 days. Cisplatin-induced nephrotoxicity was detected by a significant increase in plasma urea and creatinine levels in addition to alterations in kidney tissue morphology. Levels of TNF-α and IL-1β were significantly increased in the renal tissue in cisplatin group. Moreover, glutathione (GSH concentration and superoxide dismutase activity were significantly reduced in renal tissue in cisplatin group compared with control animals. Treatment with morphine aggravated the deleterious effects of cisplatin at clinical, biochemical and histopathological levels; whereas naltrexone diminished the detrimental effects of morphine in animals receiving morphine and cisplatin. Morphine or naltrexone alone had no effect on the mentioned parameters. Our findings indicate that concomitant treatment with morphine might intensify cisplatin-induced renal damage in rats. These findings suggest that morphine and other opioids should be administered cautiously in patients receiving cisplatin chemotherapy.

  10. Evaluating the Impact of Naltrexone on the Rat Gambling Task to Test Its Predictive Validity for Gambling Disorder.

    Full Text Available Gambling Disorder has serious consequences and no medications are currently approved for the treatment of this disorder. One factor that may make medication development difficult is the lack of animal models of gambling that would allow for the pre-clinical screening of efficacy. Despite this, there is evidence from clinical trials that opiate antagonists, in particular naltrexone, may be useful in treating gambling disorder. To-date, the effects of naltrexone on pre-clinical models of gambling have not been evaluated. The purpose of the present study was to evaluate the effects of naltrexone in an animal model of gambling, the rat gambling task (rGT, to determine whether this model has some predictive validity. The rGT is a model in which rats are given a choice of making either a response that produces a large reward or a small reward. The larger the reward, the greater the punishment, and thus this task requires that the animal inhibit the 'tempting' choice, as the smaller reward option produces overall the most number of rewards per session. People with gambling disorder chose the tempting option more, thus the rGT may provide a model of problem gambling. It was found that naltrexone improved performance on this task in a subset of animals that chose the 'tempting', disadvantageous choice, more at baseline. Thus, the results of this study suggest that the rGT should be further investigated as a pre-clinical model of gambling disorder and that further investigation into whether opioid antagonists are effective in treating Gambling Disorder may be warranted.

    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.

    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.

    People suffering from substance dependence suffer from various sexual dysfunctions and are at risk for indulging in various high-risk sexual behaviors and thus are vulnerable to acquire various infections such as HIV/AIDS and other sexually transmitted infections. The aim of the study was to evaluate the correlation between sexual dysfunction and high-risk sexual behavior in opioid-dependent men receiving buprenorphine and naltrexone maintenance therapy. Semi-structured questionnaire, brief male sexual functioning inventory and HIV-risk taking behavior scale was administered to a sample of 60 sexually active men, receiving buprenorphine (n = 30) and naltrexone (n = 30) maintenance therapy for opioid dependence. The main outcomes are correlation between severity of sexual dysfunction and HIV-risk taking behavior. The study results showed 83% of the men on buprenorphine and 90% on naltrexone reported at least one of the sexual dysfunction symptoms. There was a negative correlation between sexual dysfunction and HIV-risk taking behavior that suggest severe the dysfunction, higher the risk taking behavior. Significant correlation was present with overall sexual dysfunction and HIV-risk taking behavior (P = 0.028 and in naltrexone receiving group premature ejaculation versus HIV-risk taking behavior however, (P = 0.022, P sexual dysfunctions and HIV-risk taking behavior, which has clinical implication. Future research should explore this further using biochemical analyses.

    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 Fibromyalgia (FM is a complex, multi-symptom condition that predominantly affects women. The majority of those affected are unlikely to gain significant symptomatic control from the few treatments that are approved for FM. In this 10-week, single-blind, crossover trial we tested the immune effects of eight weeks of oral administration of low-dose naltrexone (LDN. We enrolled eight women with an average age of 46 years, symptom severity of 62 out of 100, and symptom duration of 14 years. We found that LDN was associated with reduced plasma concentrations of interleukin (IL-1β, IL-1Ra, IL-2, IL-4, IL-5, IL-6, IL-10, IL-12p40, IL-12p70, IL-15, IL-17A, IL-27, interferon (IFN-α, transforming growth factor (TGF-α, TGF-β, tumor necrosis factor (TNF-α, and granulocyte-colony stimulating factor (G-CSF. We also found a 15% reduction of FM-associated pain and an 18% reduction in overall symptoms. The findings of this pilot trial suggest that LDN treatment in fibromyalgia is associated with a reduction of several key pro-inflammatory cytokines and symptoms. The potential role of LDN as an atypical anti-inflammatory medication should be explored further.

    To evaluate whether intact or crushed doses of an extended-release formulation of morphine sulfate surrounding an inner core of sequestered naltrexone (MSN) induces signs and symptoms of withdrawal in opioid-dependent patients. Randomized, double-blind, two-way crossover study. Single center. Fourteen patients with chronic moderate-to-severe noncancer pain receiving opioids were enrolled into the study; six completed the maintenance and treatment phases prior to early study discontinuation for issues with manufacturing; eight discontinued: adverse effects (4), noncompliance (1), patient decision (1), study termination (2). Patients were titrated to a stable dose of MSN (ranging from 30/1.2 to 100/4.0 mg of morphine/naltrexone) that was used in the single-dose crossover evaluation of crushed and intact MSN. Clinical Opiate Withdrawal Scale (COWS). Clinically significant withdrawal (COWS ≥ 13) was observed with rapid onset (≤0.8 hours postdose) in three patients (50 percent) following treatment with crushed MSN at the highest doses administered of ≥60/2.4 mg. Although naltrexone exposure was negligible following exposure to intact MSN, increasing plasma levels of naltrexone and 6-β-naltrexol were associated with COWS score ≥13 in patients who received crushed MSN. COWS ≥ 13 was observed in one patient receiving intact MSN without quantifiable naltrexone concentrations. Crushing the MSN capsule may precipitate moderate-to-severe signs and symptoms of opioid withdrawal in opioid-dependent individuals. The negligible exposure to naltrexone following exposure to intact MSN supports that intact capsules may be taken safely without precipitating withdrawal in opioid-dependent individuals.

    Prophylactic treatment of retinal breaks has been examined in several studies and reviews, but so far, no studies have successfully applied a systematic approach. In the present systematic review, we examined the need of follow-up after posterior vitreous detachment (PVD) - diagnosed by slit...... published before 2012. Four levels of screening identified 13 studies suitable for inclusion in this systematic review. No meta-analysis was conducted as no data suitable for statistical analysis were identified. In total, the initial examination after symptomatic PVD identified 85-95% of subsequent retinal......-47% of cases, respectively. The cumulated incidence of RRD despite prophylactic treatment was 2.1-8.8%. The findings in this review suggest that follow-up after symptomatic PVD is only necessary in cases of incomplete retinal examination at presentation.

    The effects of prophylactic oral Ca supplementation on blood mineral status and markers of energy balance were evaluated on 205 multiparous Jersey cows at a commercial dairy. Postpartum, cows were systematically assigned to control (n = 105) or oral Ca supplementation (CaOS; 50 to 60 g of Ca as boluses; n = 100) at 0 and 1 d in milk (DIM). Blood samples for analysis of serum minerals (Ca, P, Mg, K, Na, Fe, Zn, and Cu) were collected before and 1 h after treatment at 0 and 1 DIM, and at 2 DIM. Urine pH was measured immediately before and 1 h after treatment administration (n = 96). A subset of 74 cows was evaluated for plasma glucose and fatty acid concentrations at 0, 1, and 2 DIM. Cows were classified according to their initial calcemic status (Ca status) as normocalcemic (NC; serum Ca >2.12 mmol/L) or subclinically hypocalcemic (SCH; serum Ca ≤2.12 mmol/L). Average serum Ca concentration was higher in CaOS than control cows (2.12 vs. 2.06 mmol/L); this treatment effect was higher for SCH [CaOS (2.03 mmol/L); control (1.89 mmol/L)] than NC cows [CaOS (2.22 mmol/L); control (2.22 mmol/L)]. The incidence of subclinical hypocalcemia was lower for CaOS than control cows (53 vs. 65%); however, at 2 DIM the prevalence of subclinical hypocalcemia tended to be higher for CaOS cows, mostly because it was higher for CaOS-NC than control-NC cows (70 vs. 25%). Urine pH was lower for CaOS than control cows (6.10 vs. 7.04). Lower serum Mg concentration was detected for CaOS-SCH (1.06 mmol/L) than for control-SCH (1.10 mmol/L) cows. Cows in the CaOS group had higher serum K (4.68 vs. 4.53 mmol/L), lower plasma glucose (2.97 vs. 3.10 mmol/L), and at 2 DIM higher plasma fatty acid concentrations (0.43 vs. 0.35 mmol/L) than control cows. Our results showed that postpartum serum Ca concentration increases with oral Ca supplementation, but calcemic status influenced treatment response. Future studies should evaluate the long-term implications on production and reproduction of oral

    To compare the efficacy of acamprosate and naltrexone in the treatment of alcohol dependence. A double-blind, placebo-controlled trial. Three treatment centres in Australia. A total of 169 alcohol dependent subjects were given naltrexone (50 mg/day), acamprosate (1998 mg/day) or placebo for 12 weeks. All subjects were offered manualized compliance therapy, a brief intervention that targets problems that may affect treatment compliance such as ambivalence and misperceptions about medication. Time to the first drink, time to first relapse, drinks per drinking day and cumulative abstinence. In intention-to-treat analyses, there were no differences between groups on outcome measures of drinking, craving or biochemical markers. Similarly, analyses of the 94 subjects that completed the study in full and demonstrated 80% compliance, revealed no significant treatment effects. Differential treatment effects were identified after stratification according to scores on the Alcohol Dependence Scale (ADS) and Depression Anxiety and Stress Scale (DASS). A significant beneficial treatment effect on time to first relapse was revealed for subjects with 'no depression' allocated to naltrexone (n = 56; P relapse prevention of alcoholism amongst those with low levels of clinical depression and alcohol dependence severity. No effect of acamprosate was found in our sample.

    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

    2017-05-01

    To design a molecularly imprinted polymer (MIP) for naltrexone, calculations were performed using Gaussian 03 software, and the interaction energy (ΔE) of template-monomer complexes was estimated using the density functional theory method with the B3LYP function and 6-311G (d) basis set. The effect of different solvents in the polymerization process was studied using the polarizable continuum model. It was shown that five molecules of methacrylic acid gave the largest ΔE with tetrahydrofuran as the polymerization solvent. Effective factors of the removal efficiency of naltrexone by the MIP were selected using a central composite design, and thereafter, the optimization of significant factors was performed by response surface methodology. The results predicted through these models showed good agreement with experimental values. The adsorption amount, selectivity distribution coefficient, and selectivity coefficient were found to be 11.60 mg/g, 35.31, and 2.27, respectively. Experiments of naltrexone adsorption onto the MIP were in accordance with the first-order and Langmuir-Freundlich adsorption models. By applying the data to the Scatchard equation, the KD and Qmax were determined as 526.31 mg/L and 19.47 mg/g, respectively.

    Full Text Available Introduction: Traumatic ulcers are one of the most common causes of referral to emergency wards and interfere with wound healing. Even in a complete sterile condition, all of the ulcers may be contaminated with bacteria, but a few of them progress and cause clinical manifestations. There is a controversy on the use prophylactic antibiotics in traumatic ulcers. In this study we compare the efficacy of oral and injectable forms of antibiotics in prophylaxis of infection. Methods: In this clinical trial study, 237 cases suffering from grade II traumatic ulcers were selected by simple random method and divided into 2 groups; first group was administered 1 gram cephazoline prior to suturing and received no other antibiotics , while the second group received 500 mg cephalexin capsule before suturing and continued the treatment for 24 hours. (500 mg QID .Patients were followed up on day 7, 10 and 30 after discharge from hospital for infection of the wounds. The collected data was analyzed by SPSS 11 software using Chi-squire and Fisher exact tests. Results: According to the findings, confounding variables such as sex, age, width of the wound, traumatic cause and site and also the time course until referral to the emergency ward were similar in both groups. Prevalence of infection in the group receiving oral and injection forms of antibiotic was 2.5% and 1.7%, respectively, difference of which was not significant.(P=0.683 Conclusion: As the prevalence of wound infection is similar in both groups, oral forms of antibiotics can be used instead of injectable forms for wound infection prophylaxis.

    This study was conducted to determine whether exposure to RFR might induce sufficient thermal stress to activate endogenous opioid mechanisms and induce analgesia. Male Swiss Webster mice, 20-25 g, were exposed to 10, 15 or 20 mV/cm{sup 2} RFR in a 2,450-MHz waveguide system for 10 min, then tested in the abdominal constriction paradigm. Specific absorption rates (SAR) were 23.7 W/kg at 10 mW/cm{sup 2}, 34.6 W/kg at 15 mW/cm{sup 2} and 45.5 W/kg at 20 mW/cm{sup 2}. Confinement in the exposure chamber alone did not appreciably alter body temperature but did appear to induce a stress-associated analgesia that was insensitive to the opioid receptor blocker naltrexone. Exposure of confined mice to RFR elevated body temperature and further increased analgesia in SAR-dependent manner. The high-SAR RFR-induced analgesia, but not the hyperthermia, was reduced by naltrexone. These findings suggest that (1) RFR produces SAR-dependent hyperthermia and analgesia and (2) RFR-induced analgesia is mediated by opioid mechanisms while confinement-induced analgesia involves non-opioid mechanisms.

    Obesity is a growing health problem leading to high rates of mortality and morbidity in patients with severe mental illness (SMI). The increased rate of obesity is largely attributed to antipsychotic use. The effect of antipsychotic medications on H1 and 5HT2 receptors has been associated with weight gain, but there is also a substantial amount of evidence showing that D2 receptor blockade may be responsible for weight gain by interacting with the dopamine-opioid system. Unfortunately, current available medications for weight loss have limited efficacy in this population. Naltrexone, an opioid receptor antagonist, may be a promising agent to reduce antipsychotic induced weight gain by decreasing food cravings. We aim to investigate the safety and efficacy of two doses of naltrexone (25 mg & 50 mg) versus placebo for weight and health risk reduction in overweight and obese individuals (BMI ≥ 28) with SMI, who gained weight while being treated with antipsychotics. One hundred and forty four patients will be recruited throughout the greater New Haven area. The participants will be randomized to naltrexone 25 mg/day, naltrexone 50 mg/day, or placebo in a 1:1:1 ratio. Participants will be on the study medication for 52 weeks, and assessed weekly for the first 4 weeks and bi-weekly thereafter. The primary outcome measurements are weight reduction and percentage achieving clinically significant weight loss (5% of total body weight). Waist circumference, body mass index, serum lipid profile, fasting glucose, and glycosylated hemoglobin are the secondary outcome measures. The effect of naltrexone on other outcome measurements such as schizophrenia symptoms, depression, dietary consumption, quality of life, cognitive functioning, physical activity, metabolism/inflammation markers, serum leptin, ghrelin, peptide YY, adinopectin, high sensitivity CRP, interleukin 6, interleukin-1B, interleukin-18, and tumor necrosis factor alpha (TNF-α) will be evaluated.

    Full Text Available Naltrexone is a front-line treatment for alcohol use disorders, but its efficacy is limited by poor medication adherence. This randomized controlled trial evaluated whether a mobile health intervention could improve naltrexone adherence.Treatment-seeking participants with an alcohol use disorder (N = 76 were randomized to intervention and control conditions. All participants received naltrexone (50 mg/day with a medication event monitoring system (MEMS and a prepaid smartphone, and received a daily text message querying medication side effects, alcohol use, and craving. Those in the intervention arm received additional medication reminders and adherence assessment via text message.The primary outcome, proportion of participants with adequate adherence (defined as ≥80% of prescribed doses taken through Week 8, did not differ between groups in intent-to-treat analyses (p = .34. Mean adherence at study midpoint (Week 4 was 83% in the intervention condition and 77% in the control condition (p = .35. Survival analysis found that the intervention group sustained adequate adherence significantly longer (M = 19 days [95% CI = 0.0-44.0] than those in the control group (M = 3 days [95% CI = 0.0-8.1] during the first month of treatment (p = .04. Medication adherence did not predict drinking outcomes.These results suggest that in the context of daily monitoring and assessment via cell phone, additional text message reminders do not further improve medication adherence. Although this initial trial does not provide support for the efficacy of text messaging to improve adherence to pharmacotherapy for alcohol use disorders, additional trials with larger samples and alternate designs are warranted.ClinicalTrials.gov: NCT01349985.

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

    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.

  16. The role of prophylactic cranial irradiation in small cell lung cancer

    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

    This study investigated the process of change by modeling transitions among four clinical states encountered in 64 detoxified opiate-dependent individuals treated with daily oral naltrexone: no opiate use, blocked opiate use (i.e., opiate use while adhering to oral naltrexone), unblocked opiate use (i.e., opiate use after having discontinued oral naltrexone), and treatment dropout. The effects of baseline characteristics and two psychosocial interventions of differing intensity, behavioral naltrexone therapy (BNT) and compliance enhancement (CE), on these transitions were studied. Participants using greater quantities of opiates were more likely than other participants to be retained in BNT relative to CE. Markov modeling indicated a transition from abstinence to treatment dropout was approximately 3.56 times greater among participants in CE relative to participants in BNT, indicating the more comprehensive psychosocial intervention kept participants engaged in treatment longer. Transitions to stopping treatment were more likely to occur after unblocked opiate use in both treatments. Continued opiate use while being blocked accounted for a relatively low proportion of transitions to abstinence and may have more deleterious effects later in a treatment episode.

    Medication for the treatment of alcoholism is currently not particularly robust. Neuroimaging techniques might predict which medications could be useful in the treatment of alcohol dependence. To explore the effect of naltrexone, ondansetron hydrochloride, or the combination of these medications on cue-induced craving and ventral striatum activation. Functional brain imaging was conducted during alcohol cue presentation. Participants were recruited from the general community following media advertisement. Experimental procedures were performed in the magnetic resonance imaging suite of a major training hospital and medical research institute. Ninety non-treatment-seeking alcohol-dependent (by DSM-IV criteria) and 17 social drinking (analysis but intermediate in a region-specific analysis. Consistent with animal data that suggest that both naltrexone and ondansetron reduce alcohol-stimulated dopamine output in the ventral striatum, the current study found evidence that these medications, alone or in combination, could decrease alcohol cue-induced activation of the ventral striatum, consistent with their putative treatment efficacy.

    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.

    Kleptomania is an impulse control disorder characterized by a recurrent failure to resist the impulse to steal worthless objects that are not needed for personal use. Very little is known about the etiology, prevalence and treatment. This disorder usually begins during puberty and lasts until late adulthood. In some patients, it may last throughout the person's life. Patients with kleptomania are likely to suffer from comorbid conditions like mood disorders. The patients usually seek treatment for the comorbid psychiatric complaints, rather than the kleptomaniac behavior itself. The literature lacks sufficient knowledge and controlled studies about the treatment of kleptomania. Regarding the treatment of SSRIs, there are case reports and case series, using mood stabilizers, antipsychotics and opioid antagonists. Cognitive behavioral therapy techniques are also used in the treatment of kleptomania. In this study, a female patient is presented with diminishing kleptomaniac symptoms after naltrexone is added to her cognitive behavioral therapy and fluoxetine treatment. She also suffers from the comorbidities of major depressive disorder and obsessive compulsive disorder.

    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.

    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)

    Methadone and buprenorphine are among the most widely employed pharmacological treatments currently available for opioid addiction. Cognitive effects of buprenorphine in abstinent heroin abusers are nevertheless far from being understood. Neuropsychological performance of 18 buprenorphine-maintained patients (BMP) was evaluated relative to that of 32 currently abstinent heroin abusers on naltrexone hydrochloride therapy (FHAN), and 34 non-drug dependent controls. The three groups were demographically balanced. Clinical groups reported histories of similar patterns of drug use and had increased periods of abstinence from any illicit substance use including heroin. The BMP group performed poorer than controls on the RAVLT (encoding and delayed recall of verbal information), CTT (conceptual flexibility, executive functions) and the RBANS figure copy (visual perception) and delayed recall of visual information. There were no significant differences in any of the cognitive measures between the BMP and FHAN groups or between the FHAN group and controls. Furthermore, the non-differing percentage of abnormal cases between the two patient groups led us to infer that treatment with either BPM or FHAN is not accompanied by qualitative differences in the cognitive profiles of these patients. Overall, results suggest that treatment with naltrexone in abstinent heroin abusers may result in less impairment of cognitive functions compared to treatment with buprenorphine. These findings are relevant for improved prognosis and treatment strategies in opioid dependence.

    To investigate whether prophylactic antibiotics can prevent complications of measles. Community based, randomised, double blind, placebo controlled trial. Bandim Health Project study area in Bissau, Guinea-Bissau, west Africa. 84 patients with measles during a measles epidemic in Bissau in 1998 (fewer than originally planned owing to interruption by war). Sulfamethoxazole-trimethoprim (co-trimoxazole) or placebo for seven days. Pneumonia and admission to hospital. Also weight change during the first month of infection, diarrhoea, severe fever, oral thrush, stomatitis, conjunctivitis, and otitis media. The median age of the patients with measles was 5.4 (range 0.49-24.8) years. One of 46 participants who received co-trimoxazole developed pneumonia, in contrast to six of 38 participants who received placebo (odds ratio 0.08 (95% confidence interval 0 to 0.56), adjusted for age group). The number needed to treat was 7 (4 to 48). All three participants admitted to hospital had received placebo (P=0.09). The weight gain during the first month after inclusion was 15 (2-29) g/day in the placebo group and 32 (23-42) g/day in the co-trimoxazole group (P=0.04, adjusted for age group, weight for age at inclusion, measles vaccination status, and duration of disease). Significantly less conjunctivitis occurred among recipients of co-trimoxazole than placebo, as well as a non-significant tendency to less diarrhoea, severe fever, oral thrush, and stomatitis. Complications of otitis media were the same in the two groups. The group that received prophylactic antibiotics had less pneumonia and conjunctivitis and had significantly higher weight gains in the month after inclusion. The results indicate that prophylactic antibiotics may have an important role in the management of measles infection in low income countries. Clinical trials NCT00168532.

    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

    Full Text Available  INTRODUCTION. High risk of venous thrombosis in patients with multisystem trauma is associated with a number of precipitating factors, such as direct damage to vessels, prolonged immobilization, major changes in the hemostatic system, as well as possible surgical intervention.THE PURPOSE OF THE STUDY. Analysis of the incidence, echosemiotics, and evolutionof venous thrombosis in the course of various prophylactic drug therapies in patients with polytrauma.METHODS. The results of leg veins ultrasonography in 610 patients with various prophylactic drugtherapies have been analyzed over time. Antiplatelet agentswere received by 314 patients of the first group, low molecular weight heparins — 186 patients of the second group, oral anticoagulants — 110 patients of the third group. THE RESulTS Evolved thromboses varied in frequency (52.5% in the first group, 15.6% in the 2nd group and 10% in the 3rd group, prevalence, nature of the proximal border, with an increase in the proportion of nonocclusive lesions in the 2nd and 3rd groups, as well as in start time and degree of recanalization.CONCLUSION. Low molecular weight heparins and oral anticoagulants reduce the risk of venous thrombosis by 3.3 and 5 times respectively, compared to the group of patients who did not receive anticoagulants in the early posttraumatic period; recanalization begins 1−2 weeks earlier with more effective restoration of the lumen. As the number of thromboses in the course of modern anticoagulants decreases, the proportion of non-occlusive thromboses including the floating onesgrows, requiring ultrasoundobservation.

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.

    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.

    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

  1. Reward and relief dimensions of temptation to drink: construct validity and role in predicting differential benefit from acamprosate and naltrexone.

    Researchers have sought to distinguish between individuals whose alcohol use disorder (AUD) is maintained by drinking to relieve negative affect ('relief drinkers') and those whose AUD is maintained by the rewarding effects of alcohol ('reward drinkers'). As an opioid receptor antagonist, naltrexone may be particularly effective for reward drinkers. Acamprosate, which has been shown to down-regulate the glutamatergic system, may be particularly effective for relief drinkers. This study sought to replicate and extend prior work (PREDICT study; Glöckner-Rist et al. ) by examining dimensions of reward and relief temptation to drink and subtypes of individuals with distinct patterns of reward/relief temptation. We utilized data from two randomized clinical trials for AUD (Project MATCH, n = 1726 and COMBINE study, n = 1383). We also tested whether classes of reward/relief temptation would predict differential response to naltrexone and acamprosate in COMBINE. Results replicated prior work by identifying reward and relief temptation factors, which had excellent reliability and construct validity. Using factor mixture modeling, we identified five distinct classes of reward/relief temptation that replicated across studies. In COMBINE, we found a significant class-by-acamprosate interaction effect. Among those most likely classified in the high relief/moderate reward temptation class, individuals had better drinking outcomes if assigned to acamprosate versus placebo. We did not find a significant class-by-naltrexone interaction effect. Our study questions the orthogonal classification of drinkers into only two types (reward or relief drinkers) and adds to the body of research on moderators of acamprosate, which may inform clinical decision making in the treatment of AUD. © 2016 Society for the Study of Addiction.

    The introduction of newly formulated extended release (ER) morphine with sequestered naltrexone (Embeda) has provided another treatment option for moderate to severe persistent pain. Embeda was designed to be an abuse-deterrent opioid formulation. Naltrexone is a centrally acting opioid receptor antagonist that blocks the action of opioid. When taken as directed, insignificant amount of sequestered naltrexone would reach systemic circulation, but upon tampering, the released naltrexone may blunt the euphoria of opioids, and possibly precipitate opioid withdrawal in opioid-dependent patient. To describe a case report ofa 50-year-old opioid-dependent male who developed acute opioid withdrawal after taking crushed Embeda. A 50-year-old male with severe, chronic low back pain due to degenerative disc disease was referred to our clinic for pain management. He was taking ER oxycodone 80 mg tid and Roxicodone 30 mg qid prn, with inadequate pain relief A trial of ER oxymorphone was decided, at 40 mg 1-2 doses bid. The patient returned to the clinic 1 week early, out of his ER oxymorphone. At this time, the decision to switch him to Embeda was made, at 80 mg/3.2 mg, 1-2 doses bid. The patient and his family members were counseled about risk involved with tampering with Embeda. A few hours later, our clinic was informed that the patient was brought to emergency room by ambulance, in severe opioid withdrawal. He was treated with IV fluid, antiemetics, clonidine, and IV hydromorphone. His condition improved and he was discharged home the next morning. Later on, the patient admitted that he took two prescribed Embeda within half an hour, the 1st one whole and the 2nd one crushed. He further admitted that he did so against our medical advice. CONCLUSION. Taking tampered Embeda may precipitate opioid withdrawal in opioid-tolerant patient. To the best of our knowledge, this is the first report of induced opioid withdrawal following consumption of crushed Embeda.

    This was to study children with early detected externalising behaviour problems compared to matched controls regarding oral health, oral health risk behaviour and the parental evaluation of the child's oral health and dental care. Children aged 10-13 years and with externalising behaviour problems, were compared to matched controls. Behavioural characteristics were based on the Strength and Difficulties Questionnaire. The children and their parents completed questionnaires regarding dental fear, tooth brushing, dietary habits and evaluation of oral health and dental care. Data on dental caries risk assessments, caries, behaviour management problems and dental trauma were obtained from dental files. There were no differences in caries prevalence in children with early detected externalising behaviour problems, compared to controls. However, the former group consumed more sweet drinks when thirsty and brushed their teeth fewer than twice daily; they also had more dental trauma in both dentitions and a higher risk range for dental fear, compared to controls. This study points out potential oral health risk factors in children with early-detected externalising behaviour problems. Although no difference in caries prevalence was observed, externalising behaviour may affect oral health. Therefore, dental professionals should support the families and the children to preserve dental health by offering increased prophylactic measures. There were no differences between children with externalising behaviour problems, compared with controls, regarding the parent evaluation of their child's dental health. However, more parents in the study group evaluated the dental care as poor or not functioning.

    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

    Circadian rhythm affects drug-induced reward behaviour and the innate immune system. Peaks in reward-associated behaviour and immune responses typically occur during the active (dark) phase of rodents. While the role of the immune system, specifically, Toll-like receptor 4 (TLR4, an innate immune receptor) in drug-induced reward is becoming increasingly appreciated, it is unclear whether its effects vary according to light-cycle. Therefore, the aim of this study was to characterise the effects of the phase of the light-cycle and the state of the innate immune system on alcohol reward behaviour and subsequently determine whether the efficacy of targeting the immune component of drug reward depends upon the light-cycle. This study demonstrates that mice exhibit greater alcohol-induced conditioned place preference and alcohol two-bottle choice preference during the dark cycle. This effect overlapped with elevations in reward-, thirst- and immune-related genes. Administration of (+)-Naltrexone, a TLR4 antagonist, reduced immune-related gene mRNA expression and alcohol preference with its effects most pronounced during the dark cycle. However, (+)-Naltrexone, like other TLR4 antagonists exhibited off-target side effects, with a significant reduction in overall saccharin intake - an effect likely attributable to a reduction in tyrosine hydroxylase (Th) mRNA expression levels. Collectively, the study highlights a link between a time-of-day dependent influence of TLR4 on natural and alcohol reward-like behaviour in mice. Copyright © 2017 Elsevier Inc. All rights reserved.

    Most post-traumatic acute infectious endophthalmitis occur within a week of open globe trauma, necessitating early antibiotic prophylaxis. There are few randomised studies that demonstrate the benefits of prophylactic antibiotics. This randomised controlled non-inferiority trial was aimed at determining the incidence of post-traumatic endophthalmitis using established intravenous/oral prophylaxis and comparing this to the incidence using oral antibiotics only. All adult patients admitted with open globe injury were included. Those with proven endophthalmitis, high-risk features, who underwent primary evisceration and those allergic to the trial antibiotics were excluded. Patients were randomised to receive either intravenous cefazolin and oral ciprofloxacin or oral ciprofloxacin and oral cefuroxime for 3 days from admission. Acute endophthalmitis was the primary outcome. Patients completed the study if they were followed up for 6 weeks post injury. Three hundred patients were enrolled, with 150 in each arm. There were 99 exclusions. Seven patients developed endophthalmitis despite prophylaxis-2.0% (three cases) in the intravenous and oral arm, compared with 2.7% (four cases) in the oral-only arm-this difference was not statistically significant ( p=0.703). The incidence of endophthalmitis with prophylaxis was 2-3%. Selected patients with open globe injuries (without high-risk features) may receive either intravenous cefazolin and oral ciprofloxacin, or oral cefuroxime and oral ciprofloxacin as prophylaxis against acute endophthalmitis-the latter regimen has the advantage of shortening patients' hospital stays and reducing costs. Non-inferiority study-design limitations should be taken into account, however. Published by the BMJ Publishing Group Limited.

    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.

    Full Text Available Background: About 8 percent of Iranian adult population are illicit drug abusers. Affected persons grow more each day. Ominous consequences such as divorce, prostitution, murder and other crimes and infectious diseases such as AIDS and hepatitis take place following drug abuse, as well as a loss equall to 29% of national income for our country. Traditional treatment methods wasted too much time and cost. professional inpatient clinics are not adequate for admission of all care seekers. Rapid detoxification methods are supposed to be better alternatives. Materials and Methods: 140 male drug abusers in two matched groups were assessed from March to September, 2005. They used heroin or opium. Both groups were scheduled for detoxification and were closely observed for 3 months thereafter. First group received Clonidine, Benzodiazepine and Naltrexone besides symptom relieving modalities in first 4 days of treatment. Naltrexone was continued in maintenance dose for one month. Second group received Methadone for one month. Results: Clients age was between 18 to 73 years, with mean age 34 years old. Their intelligence quotients were above the lower limit of normal range. There was no significant difference according to these parameters between two groups. Success rate in rapid detoxification group was 55 % and in Methadone group was 50 %. Relapse in rapid detoxification method occurred less frequent and slower (45 % vs. 50%. In Naltrexone group, better success rate was due to less duration of drug abuse and heroin dependency. In Methadone group, therapy had better results in patients with longer drug abuse history and opium addiction. There was no significant difference between success rate and either drug kind or job, marital status or education level. The most serious adverse effect in both groups was hypotension (10% in Naltrexone and 5 % in Methadone groups.

    Clinical evaluation of oral microbial reduction after a standard prophylactic treatment has traditionally been based on bacterial cultivation methods. However, not all microbes in saliva or dental plaque can be cultivated. Polymerase chain reaction-based denaturing gradient gel electrophoresis (PCR-DGGE) is a cultivation-independent molecular fingerprinting technique that allows the assessment of the predominant bacterial species present in the oral cavity. This study sought to evaluate the oral microbial changes that occurred after a standard prophylactic treatment with a conventional oral care product using PCR-DGGE. Twelve healthy adults participated in the study. Pooled plaque samples were collected at baseline, 24 h after prophylaxis (T1), and 4 days after toothbrushing with fluoride toothpaste (T4). The total microbial genomic DNA of the plaque was isolated. PCR was performed with a set of universal bacterial 16S rDNA primers. The PCR-amplified 16S rDNA fragments were separated by DGGE. The effects of the treatment and of dental brushing were assessed by comparing the PCR-DGGE fingerprinting profiles. The mean numbers of detected PCR amplicons were 22.3 +/- 6.1 for the baseline group, 13.0 +/- 3.1 for the T1 group, and 13.5 +/- 4.3 for the T4 group; the differences among the three groups were statistically significant (P < 0.01). The study also found a significant difference in the mean similarities of microbial profiles between the baseline and the treatment groups (P < 0.001). PCR-based DGGE has been shown to be an excellent means of rapidly and accurately assessing oral microbial changes in this clinical study.

    Cocaine use disorder remains a significant public health issue for which there are no FDA-approved pharmacotherapies. Amphetamine maintenance reduces cocaine use in preclinical and clinical studies, but the mechanism of this effect is unknown. Previous studies indicate a role for endogenous opioid release and subsequent opioid receptor activation in some amphetamine effects; therefore, the current study examined the role of mu-opioid receptor activation in d-amphetamine treatment effects in an assay of cocaine-vs-food choice. Adult male rhesus monkeys with double-lumen intravenous catheters responded for concurrently available food pellets and cocaine injections (0-0.1mg/kg/injection) during daily sessions. Cocaine choice and overall reinforcement rates were evaluated during 7-day treatments with saline or test drugs. During saline treatment, cocaine maintained a dose-dependent increase in cocaine-vs.-food choice. The mu-opioid receptor agonist morphine (0.032-0.32mg/kg/h) dose-dependently increased cocaine choice and decreased rates of reinforcement. A dose of the mu-selective opioid receptor antagonist naltrexone (0.0032mg/kg/h) that completely blocked morphine effects had no effect on cocaine choice when it was administered alone, but it enhanced the effectiveness of a threshold dose of 0.032mg/kg/h amphetamine to decrease cocaine choice without also enhancing nonselective behavioral disruption by this dose of amphetamine. Conversely, the kappa-selective opioid antagonist norbinalorphimine did not enhance amphetamine effects on cocaine choice. These results suggest that amphetamine maintenance produces mu opioid-receptor mediated effects that oppose its anti-cocaine effects. Co-administration of naltrexone may selectively enhance amphetamine potency to decrease cocaine choice without increasing amphetamine potency to produce general behavioral disruption.

    2015-05-01

    Results: There were 16 newborns in each group (20 boys and 12 girls. In 12 newborns of prophylaxis group the ductus arteriosus was closed although in control group in 8 newborns the duct was closed. No significant difference was observed in sex, gestational age, birth weight, mode of delivery, multifetal gestation and birth order between two groups. The rate of ductal closure was 75% and 50% in prophylaxis group and control group respectively (P=0.27. Conclusion: Our study demonstrated that prophylactic paracetamol is ineffective in PDA closure, although the rate of ductal closure between two groups seems remarkable. Paracetamol as a new strategy for PDA closure because of cost effectiveness and harmlessness may be used in future. However, we presume larger sample size studies are needed to show the efficacy of paracetamol, side effects, and complications in PDA prophylaxis treatment.

    The purpose of this study was to assess the value of sucralfate suspension in prevention of oral mucositis and for reduction of oral pain in patients who develop mucositis during radiation therapy. The study was a double-blind, placebo-controlled, randomized prospective trial of a sucralfate suspension in the prevention and management of oral mucositis during radiation therapy. Oral mucositis was assessed using a quantitative scale and symptoms were assessed using visual analogue scales. The statistical model was developed to detect a 40% reduction in mucositis. No statistically significant reduction in mucositis was seen. Early during radiation therapy less oral pain was reported in the sucralfate group, but as treatment progressed all patients experienced pain. Patients in the sucralfate group were prescribed topical and systemic analgesics later in the course of radiation therapy. Prophylactic oral rinsing with sucralfate did not prevent oral ulcerative mucositis. Sucralfate may reduce the experience of pain during radiation therapy. 32 refs., 3 tabs

    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.

    Full Text Available Abstract Background Prophylactic treatment is an important but under-utilised option for the management of migraine. Patients and physicians appear to have reservations about initiating this treatment option. 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.

    Repeated exposure of rats to pulsed, circularly polarized microwaves (2,450-MHz, 2-microseconds pulses at 500 pps, power density 1 mW/cm2, at an averaged, whole-body SAR of 0.6 W/kg) induced biphasic changes in the concentration of muscarinic cholinergic receptors in the central nervous system. An increase in receptor concentration occurred in the hippocampus of rats subjected to ten 45-min sessions of microwave exposure, whereas a decrease in concentration was observed in the frontal cortex and hippocampus of rats exposed to ten 20-min sessions. These findings, which confirm earlier work in the authors' laboratory, were extended to include pretreatment of rats with the narcotic antagonist naltrexone (1 mg/kg, IP) before each session of exposure. The drug treatment blocked the microwave-induced changes in cholinergic receptors in the brain. These data further support the authors' hypothesis that endogenous opioids play a role in the effects of microwaves on central cholinergic systems.

    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.

    Full Text Available Acute weaning from chronic opioid abuse during general anesthesia is usually followed by adrenergic outflow effects. This article is to report our experience with accelerated neuroregulation that reverses the physical and psychological dependency. After a comprehensive psychological and medical examination, 361 heroin dependent patients were admitted to ICU to be hospitalized for a full 24 or 36 hours, including a 6 hour pre-procedure medication process (solbutamol, clonidine, diazepam, ranitidine, omeprazole, vitamin C, octreotide, and ondansetron. Anesthesia was induced with midazolam and propofol iv and maintained with propofol infusion. Naltrexon, clonidine, octreotide, and diazepam were then administered. Anesthesia was maintained for 3 ½ - 5 hours depending on severity of withdrawal symptoms precipitated by naltrexone. Analgetics and sedatives were given as needed afterwards. Upon discharge on the following day, patient was prescribed a regimen of oral naltrexone for 10-12 months. All 361 patients were successfully detoxified without any adverse anesthetic events. The side effects encountered were fatigue, insomnia, drowsy, shivering, abdominal pain, nausea, diarrhoea, myalgia, goose bumps and uncomfortable feeling. In most of the patients these symptoms disappeared without any treatment. Symptomatic treatments were needed in 32.7% of patients. In all 166 patients who completed their naltrexone maintenance treatment, craving disappeared in the 10th month. The main problem was the low patient compliance to oral naltrexone, so that only 45.9% of the patients completed their therapy. Conclusion: Accelerated neuroregulation which includes naltrexone maintenance treatment (10-12 months was highly effective to detoxify and to abolish craving in the heroin dependent patients.

    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.

    Postoperative urinary retention (POUR) is one of the most common complications after surgical procedures under spinal anaesthesia. Recent studies have shown the beneficial effects of alpha-adrenergic blockers in preventing POUR. The aim of this prospective study was to investigate and compare the prophylactic effects of tamsulosin and alfuzosin on POUR after urologic surgical procedures under spinal anaesthesia. A total of 180 males who underwent elective urologic surgery were included in this study. The patients were randomly allocated into three Groups. The Group I received placebo. Patients in Group II were given 0.4mg of tamsulosin orally 14 and 2 hours before surgery. Patients in Group III were given 10mg of alfuzosin ER orally 10 and 2 hours before surgery. All patients were closely followed for 24 hours postoperatively and their episodes of urinary retentions were recorded. There were 60 patients in each Group. Their mean age was 35.95±15.16 years. Fifteen patients in Group I (25%), 3 patients in Group II (5%) and 4 patients in Group III (6.7%) required catheterization because of urinary retention. In tamsulosin group and alfuzosin group, there were a significantly lower proportion of patients with POUR compared with the placebo Group (p=0.002 and p=0.006). The beneficial effects of tamsulosin and alfuzosin on POUR were similar between both Groups (p=0.697). This study suggests that the use of prophylactic tamsulosin or alfuzosin can reduce the incidence of urinary retention and the need for catheterization after urologic surgical procedures under spinal anaesthesia.

    Regorafenib is an oral multikinase inhibitor with a proven survival benefit for metastatic colorectal cancer patients. The KSCC1402/HGCSG1402 study investigated the prophylactic effect of oral dexamethasone (DEX) on regorafenib-related fatigue and/or malaise. Patients who progressed after standard chemotherapy were randomized 1: 1 to a DEX group (2 mg/day; days 1-28) with regorafenib or a placebo group with regorafenib. The primary endpoint was the incidence of fatigue and/or malaise, based on version 4.0 of the National Cancer Institute's CTCAE (Common Terminology Criteria for Adverse Events). One of the secondary endpoints was the in-cidence of fatigue and/or malaise based on the CTCAE assessed by patient-reported outcome (PRO). The incidence of any grade of fatigue and/or malaise assessed by the investigators was 58.8% in the DEX group and 61.1% in the placebo group (p = 0.8101), and that assessed by PRO was 47.2 and 58.3%, respectively (p = 0.3450). The incidence of grade ≥2 fatigue and/or malaise, as assessed by the investigators, was 19.4% for the DEX group and 38.9% for the placebo group (p = 0.0695), and that assessed by PRO was 27.8 and 52.8%, respectively (p = 0.0306). Our results suggest that prophylactic oral DEX is clinically effective in improving regorafenib-related fatigue and/or malaise. © 2018 S. Karger AG, Basel.

    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

    The incidence of high blood pressure in adults is estimated at ca. 30-40% of the general population. Both hypertension disease and hypertensive drugs affect the condition of the patients' oral cavity. A review of the current literature shows that disorders most frequently found in the masticatory organ of patients with hypertension include: xerostomia, changes in salivary glands, gum hypertrophy, lichenoid lesions, taste disorders, and paraesthesias. The authors emphasize that patients with high blood pressure, along with the treatment of the underlying disease, should receive prophylactic and therapeutic dental care. This would enable reduction and/or elimination of unpleasant complaints, and also help prevent the emergence of secondary disorders in the patients' oral cavity as a result of hypertension pharmacotherapy. © 2015 MEDPRESS.

    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.

    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

    This study evaluated the efficacy of combined (intra- and extraoral) low-level laser therapy (LLLT) and conventional pharmacological modalities in prevention and treatment of oral mucositis (OM) and associated pain and xerostomia in patients with head and neck cancer (HNC) undergoing concurrent chemoradiotherapy (CRT). A prospective comparative randomized study was conducted with 21 patients with head and neck cancer subjected to CRT. Eleven patients received extra- and intraoral LLLT daily from the 1st day until the end of CRT-course before each session during 5 consecutive days, and the other 10 patients received conventional preventive and treatment procedures based on the use of benzidamine 0.15% solution also throughout the duration of CRT, including weekends. OM was measured using an oral toxicity scale (OTS), oral pain was measured using the color-numeric visual analogue scale (VAS), unstimulated salivary flow rate measured by the spitting technique (ml/min), dry mouth symptoms were self-estimated by patients using The Xerostomia Inventory (XI). The LLLT group showed lower mean OTS and VAS scores, lower level of reduction of salivary flow rate during the course of CRT. In both groups, no interruption of CRT was needed. The prophylactic use of both treatments proposed in this study seems to reduce the incidence of severe OM lesions. However, the LLLT was more effective in delaying the appearance of severe OM, oral pain and xerostomia.

    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)

    Full Text Available ABSTRACT Purpose Postoperative urinary retention (POUR is one of the most common complications after surgical procedures under spinal anaesthesia. Recent studies have shown the beneficial effects of alpha-adrenergic blockers in preventing POUR. The aim of this prospective study was to investigate and compare the prophylactic effects of tamsulosin and alfuzosin on POUR after urologic surgical procedures under spinal anaesthesia. Materials and Methods A total of 180 males who underwent elective urologic surgery were included in this study. The patients were randomly allocated into three Groups. The Group I received placebo. Patients in Group II were given 0.4mg of tamsulosin orally 14 and 2 hours before surgery. Patients in Group III were given 10mg of alfuzosin ER orally 10 and 2 hours before surgery. All patients were closely followed for 24 hours postoperatively and their episodes of urinary retentions were recorded. Results There were 60 patients in each Group. Their mean age was 35.95±15.16 years. Fifteen patients in Group I (25%, 3 patients in Group II (5% and 4 patients in Group III (6.7% required catheterization because of urinary retention. In tamsulosin group and alfuzosin group, there were a significantly lower proportion of patients with POUR compared with the placebo Group (p=0.002 and p=0.006. The beneficial effects of tamsulosin and alfuzosin on POUR were similar between both Groups (p=0.697. Conclusion This study suggests that the use of prophylactic tamsulosin or alfuzosin can reduce the incidence of urinary retention and the need for catheterization after urologic surgical procedures under spinal anaesthesia.

    Full Text Available Introduction. Given the mechanism of the development of halitosis and low efficiency of its self-elimination, means of oral hygiene with antiglycation characteristics should efficiently remove plaque and slow its formation, have antiseptic, antimicrobial and anti-inflammatory properties; have high deodorant quality, strengthen natural defense mechanisms and be safe to oral tissues and organism as a whole. Toothpastes and mouthwashes should consist of components that are able to mask and as well detoxify volatile sulphur and nitrogencontaining compounds produced by microorganisms of the oral cavity. The objective is to evaluate the dynamics of deodorant effect of the means of oral hygiene for identifying the effectiveness of preventive measures among the population.Materials and methods. At the department of preventive dentistry of the Federal State Budgetary Educational Institution of Higher Education «Pavlov First Saint Petersburg State Medical University” of the Ministry of Healthcare of the Russian Federation, we conducted the diagnostic assessment of halitosis based on the method of index determination of the deodorant effect by Ulitovsky S. B. This method allows to monitor the deodorant effect and in a single definition to determine the level of mouth breathing before using the means of hygiene.Results. The research revealed that the indicators of index determination of the deodorant effect by Ulitovsky S. B to the end of the study was 44.78±1.73 % in the 1st group and 26.92±1.61 % in the control group. Based on these data, which depended on the degree of antimicrobial activity of personal means of oral hygiene, the examined sample of prophylactic toothpaste showed the significant activity for such test cultures as Ps. aeruginosa, B. cereus and C. albicans.Conclusions. Based on the evaluating the dynamics of the deodorant effect of the means of oral hygiene throughout the study we identified the increasing of deodorant effect according

    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

    Smoking tobacco remains one of the leading causes of preventable deaths in North America. Nicotine reinforces smoking behavior, in part, by enhancing the reinforcing properties of reward-related stimuli, or conditioned stimuli (CSs), associated with tobacco intake. To investigate how pharmaceutical interventions may affect this property of nicotine, we examined the effect of four US Food and Drug Administration (FDA) approved drugs on the ability of nicotine to enhance operant responding for a CS as a conditioned reinforcer. Thirsty rats were exposed to 13 Pavlovian sessions where a CS was paired with water delivery. Nicotine (0.4 mg/kg) injections were administered before each Pavlovian session. Then, in separate groups of rats, the effects of varenicline (1 mg/kg), bupropion (10 and 30 mg/kg), lorcaserin (0.6 mg/kg), and naltrexone (2 mg/kg), and their interaction with nicotine on responding for conditioned reinforcement were examined. Varenicline and lorcaserin each reduced nicotine-enhanced responding for conditioned reinforcement, whereas naltrexone had a modest effect of reducing response enhancements by nicotine. In contrast, bupropion enhanced the effect of nicotine on this measure. The results of these studies may inform how pharmaceutical interventions can affect smoking cessation attempts and relapse through diverse mechanisms, either substituting for, or interacting with, the reinforcement-enhancing properties of nicotine.

    Opioid use disorder (OUD) frequently begins in adolescence and young adulthood. Intervening early with pharmacotherapy is recommended by major professional organizations. No prior national studies have examined the extent to which adolescents and young adults (collectively termed youth) with OUD receive pharmacotherapy. To identify time trends and disparities in receipt of buprenorphine and naltrexone among youth with OUD in the United States. A retrospective cohort study was conducted using deidentified data from a national commercial insurance database. Enrollment and complete health insurance claims of 9.7 million youth, aged 13 to 25 years were analyzed, identifying individuals who received a diagnosis of OUD between January 1, 2001, and June 30, 2014, with final follow-up date December 31, 2014. Analysis was conducted from April 25 to December 31, 2016. Time trends were identified and multivariable logistic regression was used to determine sociodemographic factors associated with medication receipt. Sex, age, race/ethnicity, neighborhood education and poverty levels, geographic region, census region, and year of diagnosis. Dispensing of a medication (buprenorphine or naltrexone) within 6 months of first receiving an OUD diagnosis. Among 20 822 youth diagnosed with OUD (0.2% of the 9.7 million sample), 13 698 (65.8%) were male and 17 119 (82.2%) were non-Hispanic white. Mean (SD) age was 21.0 (2.5) years at the first observed diagnosis. The diagnosis rate of OUD increased nearly 6-fold from 2001 to 2014 (from 0.26 per 100 000 person-years to 1.51 per 100 000 person-years). Overall, 5580 (26.8%) youth were dispensed a medication within 6 months of diagnosis, with 4976 (89.2%) of medication-treated youth receiving buprenorphine and 604 (10.8%) receiving naltrexone. Medication receipt increased more than 10-fold, from 3.0% in 2002 (when buprenorphine was introduced) to 31.8% in 2009, but declined in subsequent years (27.5% in 2014). In multivariable

    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.

    Music’s universality and its ability to deeply affect emotions suggest an evolutionary origin. Previous investigators have found that naltrexone (NTX), a μ-opioid antagonist, may induce reversible anhedonia, attenuating both positive and negative emotions. The neurochemical basis of musical experience is not well-understood, and the NTX-induced anhedonia hypothesis has not been tested with music. Accordingly, we administered NTX or placebo on two different days in a double-blind crossover study, and assessed participants’ responses to music using both psychophysiological (objective) and behavioral (subjective) measures. We found that both positive and negative emotions were attenuated. We conclude that endogenous opioids are critical to experiencing both positive and negative emotions in music, and that music uses the same reward pathways as food, drug and sexual pleasure. Our findings add to the growing body of evidence for the evolutionary biological substrates of music. PMID:28176798

    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.

    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.

    In the recent years low intensity laser irradiation is made use of in stomatology with the view of treating numerous diseases of the oral cavity mucosa and parodontium. The oral cavity mucosa lesions caused by the internal organs diseases, especially those of blood and the gastroenteric tract, constitute a particular group. Such diseases are usually manifested by an inflammation, erosions, ulcers, hemorrhages. An abundant microflora of the oral cavity and diminished immunity of the patients contribute to the possibility of septicaemia development. Laser therapy of the oral cavity mucosa lesions according to strictly defined indications promotes rapid healing of ulcers, arresting the oral cavity mucosa inflammation, providing a reduction in bleeding and presents a safe prophylactic means of stomatogenic sepsis.

    Many studies show that the human microbiome plays a critical role in the chronic pathologies of obesity, inflammatory bowel diseases, and diabetes. More recently, the interaction between cancer and the microbiome has been highlighted. Most studies have focused on the gut microbiota because it represents the most extensive bacterial community, and the body of evidence correlating it with gut syndromes is increasing. However, in the strict sense, the gastrointestinal (GI) tract begins in the oral cavity, and special attention should be paid to the specific flora of this cavity. This study reviewed the current knowledge about the various microbial ecosystems of the upper part of the GI tract and discussed their potential link to carcinogenesis. The overall composition of the microbial communities, as well as the presence or absence of "key species", in relation to carcinogenesis is addressed. Alterations in the oral microbiota can potentially be used to predict the risk of cancer. Molecular advances and the further monitoring of the microbiota will increase our understanding of the role of the microbiota in carcinogenesis and open new perspectives for future therapeutic and prophylactic modalities.

    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.

    Melatonin, a hormone with a proven antioxidative efficacy, crosses all morphophysiological barriers, including the blood-brain barrier, and distributes throughout the cell. The present study is an attempt to investigate the prophylactic influence of a chronic low level of melatonin against an acute radiation induced oxidative stress in the cerebellum of Swiss albino mice, with special reference to Purkinje cells. After 15 days of treatment the mice were sacrificed at various intervals from 1 to 30 days. Biochemical parameters included lipid peroxidation (LPO) and glutathione (GSH) levels as the endpoints. The quantitative study included alterations in number and volume of Purkinje cells. Swiss albino mice were orally administered a very low dose of melatonin (0.25 mg/mouse/day) for 15 consecutive days before single exposure to 4 Gy gamma radiation. Melatonin checked the augmented levels of LPO, by approximately 55%, by day 30 day post-exposure. Radiation induced depleted levels of GSH could be raised by 68.9% by day 30 post-exposure. Radiation exposure resulted in a reduction of the volume of Purkinje cells and their total number. The administration of melatonin significantly protected against the radiation induced decreases in Purkinje cell volume and number. Results indicate the antioxidative properties of melatonin resulting in its prophylactic property against radiation induced biochemical and cellular alterations in the cerebellum. The findings support the idea that melatonin may be used as an anti-irradiation drug due to its potent free radical scavenging and antioxidative efficacy.

    : A previous hip fracture more than doubles the risk of a contralateral hip fracture. Pharmacologic and environmental interventions to prevent hip fracture have documented poor compliance. 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

    Head & Neck Cancer (HNC) represents the sixth most common malignancy worldwide and it is historically linked to well-known behavioural risk factors, i.e., tobacco smoking and/or the alcohol consumption. Recently, substantial evidence has been mounting that Human Papillomavirus (HPV) infection is playing an increasing important role in oral cancer. Because of the attention and clamor surrounding oral HPV infection and related cancers, as well as the use of HPV prophylactic vaccines, in this invited perspective the authors raise some questions and review some controversial issues on HPV infection and its role in HNC, with a particular focus on oral squamous cell carcinoma. The problematic definition and classification of HNC will be discussed, together with the characteristics of oral infection with oncogenic HPV types, the frequency of HPV DNA detection in HNC, the location of HPV-related tumours, the severity and prognosis of HPV-positive HNC, the diagnosis of oral HPV infection, common routes of oral infection and the likelihood of oro-genital HPV transmission, the prevention of HPV infection and novel therapeutic approaches.

    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

    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.

  1. 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

    It is suggested that some of the behavioral effects of ethanol, including its psychomotor properties, are mediated by beta-endorphin and opioid receptors. Ethanol-induced increases in the release of hypothalamic beta-endorphin depend on the catalasemic conversion of ethanol to acetaldehyde. Here, we evaluated the locomotor activity in rats microinjected with ethanol directly into the hypothalamic arcuate nucleus (ArcN), the main site of beta-endorphin synthesis in the brain and a region with high levels of catalase expression. Intra-ArcN ethanol-induced changes in motor activity were also investigated in rats pretreated with the opioid receptor antagonist, naltrexone (0-2 mg/kg) or the catalase inhibitor 3-amino-1,2,4-triazole (AT; 0-1 g/kg). We found that ethanol microinjections of 64 or 128, but not 256 microg, produced locomotor stimulation. Intra-ArcN ethanol (128 microg)-induced activation was prevented by naltrexone and AT, whereas these compounds did not affect spontaneous activity. The present results support earlier evidence indicating that the ArcN and the beta-endorphinic neurons of this nucleus are necessary for ethanol to induce stimulation. In addition, our data suggest that brain structures that, as the ArcN, are rich in catalase may support the formation of ethanol-derived pharmacologically relevant concentrations of acetaldehyde and, thus be of particular importance for the behavioral effects of ethanol.

    Full Text Available Introduction: Antibiotic therapy before or after orthognathic surgery is commonly recommended by surgeons to minimize the risk of wound infection. This article evaluates the value of Prophylactic antibiotic therapy in order to diminish the incidence of postoperative wound infection after orthognathic surgery.   Materials and Methods: Fifty candidates for bimaxillary orthognathic surgery were divided into cases and controls. Cefazolin (1g was administered intravenously to all participants 30 mins prior to surgery followed by a similar dose 4 hours later. Case-group patients ingested amoxicillin (500 mg orally for 7 days after surgery. Postoperative wound infection was assessed using clinical features, and the P-value significance was set at P  Results: Both groups were similar according to gender, age, and operating time. During the follow-up period no infection was observed in either the case or control group.   Conclusion:  The results of this study suggest that long-term postoperative antibiotic therapy is not essential for the prevention of postoperative infection, and that application of aseptic surgical technique and hygiene instruction after surgery are sufficient.

    1997-01-01

    Background: Acute reactions of oral mucosa are a frequent side effect of radiotherapy, which often necessitates interruption of the treatment. Marked proliferation of tumor stem cells during treatment interruptions may occur in squamous cell carcinomata, which represent the majority of tumors in the head and neck area. Hence a fatal consequence of treatment breaks may be a significant decrease in tumor cure rates. Furthermore, marked acute responses frequently result in increased late sequelae ('consequential damage'). Therefore, amelioration of the mucosal response aiming at avoiding treatment breaks and at reduction of late reactions coul definitely increase the therapeutic success of radiation treatment. Results: A variety of prophylactic and therapeutic methods have been proposed for the management of acute radiation reactions of the oral mucosa. Frequently, their efficiacy has been established for chemotherapy or in combination with other immunosuppressive treatments. Hence, systemical rather than local effects have to be considered. Conclusions: In general, prophylaxis of oral mucositis is mainly based on dental restoration or edentation, in combination with frequent oral hygienic measures after the meals and with antiseptic mouthwashes. Intensive personal care is recommended. The necessity of a percutaneous endoscopic gastrostoma is dependent on the status of the patient and on size and localization of the treatment area, i.e. the impairment of food uptake which is to be expected. Therapeutic intervention is restricted to local or systemic treatment of pain and local application of antimycotics and antibiotics. (orig./VHE) [de

    2010-01-01

    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.

    Radiotherapy is one of the effective treatments for head and neck cancers, but radiation damages appear in the normal mucous membrane at high frequencies because the membrane is often positioned in the radiation area. Here, the appearance patterns of such damages and the therapeutic methods for them were briefly described. Generally, there were no subjective and objective symptoms immediately after the radiation, but those often appeared from the time around 2 weeks after the initiation of radiotherapy and when the total dose reached a level near 20 Gy. The major symptoms were as follows; flare and edema, oral dryness due to decreased salivation, taste alteration reduced appetite, infections due to reduced immunoreactivity etc. For these symptoms, some symptomatic treatments are carried out along with prophylactic ones to keep the oral cavity clean. As the local treatments; spraying of steroid agent, administrations of antiphlogistic/analgesic agents, mucous membrane protecting agents, etc. are often conducted to improve the lowering of QDL.

    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

    Full Text Available Liver cancer remains one of the severe lethal malignancies worldwide and hepatocellular carcinoma (HCC is the most common form. The current study was designed to evaluate the prophylactic role of the fruit of Averrhoa carambola (star fruit or Kamrak on diethylnitrosamine- (DENA- induced (15 mg/kg b.wt.; single i.p. injection and CCl4-promoted (1.6 g/kg b.wt. in corn oil thrice a week for 24 weeks liver cancer in Swiss albino mice. Administration of ACE was made orally at a dose of 25 mg/kg b.wt/day for 5 consecutive days and it was withdrawn 48 hrs before the first administration of DENA (preinitiational stage. CCl4 was given after 2 weeks of DENA administration. A cent percent tumor incidence was noted in carcinogen treated animals while ACE administration resulted in a considerable reduction in tumor incidence, tumor yield, and tumor burden. Further, ACE treatment brings out a significant reduction in lipid peroxidation (P<0.001 along with an elevation in the activities of enzymatic antioxidants (superoxide dismutase, P<0.001, and catalase, P<0.001, nonenzymatic antioxidant (reduced glutathione, P<0.001, and total proteins (P<0.001 when compared to the carcinogen treated control. These results demonstrate that ACE prevents the DENA/CCl4 induced adverse physical and biochemical alterations during hepatic carcinogenesis in mice. This study suggests the prophylactic role of Averrhoa carambola against hepatocellular carcinoma in mice; therefore, it could be employed for the further screening as a good chemopreventive natural supplement against cancer.

    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.

    The recent US Food and Drug Administration licensure of a prophylactic vaccine against oncogenic human papillomavirus (HPV) types 16 and 18, the first of its kind, poses unique challenges in postmarketing vaccine surveillance, especially in measuring vaccine effectiveness against biologic endpoints of HPV infection. Historically, the national system of population-based cancer registries in the US has provided high-quality data on cancer incidence and mortality for the most important biologic endpoints, namely, anogenital cancers and some oral cavity/oropharyngeal cancers. There also has been some data collection on cancer precursors; however, this activity has been inconsistent and of lower priority. Because effectiveness against HPV-associated cancers will not be measurable for several decades, strengthening and possibly expanding the capacity of registries to collect precancer data, which are earlier manifestations of infection, must be considered. Collecting type-specific data on HPV-associated precancers and cancers. While keeping in mind the current limitations of registry operations, they discuss resources that may be needed to implement and sustain these types of activities.

    While most oral surgical procedures can be safely performed in an outpatient setting, certain medical conditions may present a higher chance of postoperative complications. In particular, those predisposing the patient to bleeding abnormalities pose a potential risk when performing such treatments. The authors report a case involving full-mouth extractions in a patient with cirrhosis and thrombocytopenia after obtaining a platelet transfusion. A 62-year-old Caucasian female presented to a university special care dental clinic requiring extractions. Her pertinent medical history was remarkable for cirrhosis and thrombocytopenia, with a platelet count of 32,000/uL. Upon medical consultation, the patient was appointed for a prophylactic platelet transfusion. The surgery was rendered uneventfully, and the patient achieved adequate hemostasis without hospitalization. Patients with cirrhosis pose a potential bleeding risk with dental surgical procedures. Pre-operative medical consultation, review of pertinent laboratory values, and prophylactic platelet transfusion allow these patients to be managed safely in an outpatient setting. © 2015 Special Care Dentistry Association and Wiley Periodicals, Inc.

    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.

    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

    The purpose of this study was to investigate whether prophylactic administration of melatonin to the mother throughout pregnancy could protect against ischemia/reperfusion (I/R)-induced oxidative brain damage in neonatal rats. The utero-ovarian arteries were occluded bilaterally for 30 min in female Wistar rats on day 16 of pregnancy to induce fetal ischemia. Reperfusion was achieved by releasing the occlusion and restoring circulation. A sham operation was performed in control rats. Melatonin solution or vehicle alone was administrated orally throughout pregnancy. We collected brain mitochondria from neonatal rats, evaluated mitochondrial structure by electron microscopy, and measured the respiratory control index (RCI) as an indicator of mitochondrial respiratory activity as well as the concentration of thiobarbituric acid-reactive substances (TBARS), a marker of oxidative stress. Histological analysis was performed at the Cornu Ammonis 1 (CA1) and Cornu Ammonis 3 (CA3) regions of the hippocampus. I/R significantly reduced the RCI and significantly elevated the concentration of TBARS. Melatonin treatment reversed these effects, resulting in values similar to that in untreated, sham-ischemic animals. Electron microscopic evaluation showed that the number of intact mitochondria decreased in the I/R group, while melatonin treatment preserved them. Histological analysis revealed a decrease in the ratio of normal to whole pyramidal cell number in the CA1 and CA3 regions in the I/R group. While melatonin administration protected against degeneration. These results indicate that prophylactic administration of melatonin to the mother throughout pregnancy may prevent I/R-induced oxidative brain damage in neonatal rats.

    Purpose: To evaluate the effectiveness of prophylactic tamsulosin (Flomax) in reducing the urinary symptoms in patients undergoing 125 I prostate implantation (PI) for prostate adenocarcinoma. Methods and materials: This is a single-institution, double-blind, placebo-controlled, randomized trial for patients undergoing PI for prostate adenocarcinoma comparing prophylactic tamsulosin versus placebo. Eligibility criteria included patients not taking tamsulosin or other α-blockers treated with PI. The patients were randomly assigned to either tamsulosin (0.8 mg, orally once a day) or matched placebo. All patients started the medication 4 days before PI and continued for 60 days. The American Urologic Association (AUA) symptom index questionnaire was used to assess urinary symptoms. The AUA questionnaire was administered before PI for a baseline score and weekly for 8 weeks after PI. Patients were taken off the study if they developed urinary retention, had intolerable urinary symptoms, or wished to discontinue with the trial. Results: One hundred twenty-six patients were enrolled in this study from November 2001 to January 2003 (118 were evaluable: 58 in the tamsulosin arm and 60 in the placebo group). Pretreatment and treatment characteristics were comparably matched between the two groups. The urinary retention rate was 17% (10 patients) in the placebo group compared with 10% (6 patients) in the tamsulosin group (p = 0.3161). Eighty-eight percent (14 patients) of those who developed urinary retention experienced it within 2 weeks after the PI. Intolerable urinary symptoms were reported equally (10 patients in each group) with 70% occurring in the first 2 weeks after PI. There was a significant difference in mean AUA score in favor of tamsulosin at Week 5 after PI (p = 0.03). Conclusions: Prophylactic tamsulosin (0.8 mg/day) before prostate brachytherapy did not significantly affect urinary retention rates, but had a positive effect on urinary morbidity at Week 5

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 identify risk factors potentially associated with the development of bacterial endocarditis in dogs and determine whether periodontal disease and surgical procedures (oral and nonoral) were associated with bacterial endocarditis. Retrospective case-control study. 76 dogs with (cases) and 80 dogs without (controls) bacterial endocarditis. Medical records were reviewed for information on signalment, physical examination findings, recent medical history, and results of echocardiography, clinicopathologic testing, and necropsy. None of the dogs with endocarditis had a history of undergoing any dental or oral procedure in the 3 months prior to the diagnosis of endocarditis, and no significant difference was found between groups with regard to the prevalence of oral infection. Dogs with endocarditis were significantly more likely to have undergone a nonoral surgical procedure that required general anesthesia in the preceding 3 months or to have developed a new heart murmur or a change in intensity of an existing heart murmur. Preexisting cardiac dis-ease (congenital or acquired) was not found to be a risk factor. Results did not provide any evidence of an association between bacterial endocarditis in dogs and either dental or oral surgical procedures or oral infection. Findings suggested that the routine use of prophylactic antimicrobial administration in dogs undergoing oral procedures needs to be reevaluated.

    Full Text Available   Background: Oral clefts are among the most common congenital anomalies. Infants with oral clefts often have other associated congenital defects, especially congenital heart defects. The reported incidences and the types of associated malformations and congenital heart defects vary between different studies. The purpose of this study was to assess the incidence of associated congenital heart defects in children with oral clefts. Methods: All infants with cleft lip and palate referred to the Children's Medical Center and Bahramy; the teaching Hospitals of the Tehran University of Medical Sciences from 1991 to 2005 were prospectively enrolled in this study group. All patients were examined and noted by an academic cleft team contain; a pediatrician and a pediatric surgeon, and received cardiac consultation and echocardiography by a pediatric cardiologist. non cardiac associated anomalies, still born and patients without echocardiography were excluded from the study.  Data including age, gender, exposure to contagions and high risk elements ,consanguinity and familial history of oral cleft, type of oral cleft, results of cardiac consultation and echocardiography and associated cardiac anomalies were cumulated and analyzed by SSPS version 13.5Results: Among the 284 infants with oral clefts, 162 were male (57% and 122 were female (43%. Seventy-nine patients (27.8% had cleft lip, 84 (29.5% had cleft palate and 121 (42.6% had both cleft lip and palate. Of all the patients, 21.1% had congenital heart defects. the most common type Of these congenital heart defects(28.3%  was atrial septal defect.Conclusions: For patients with cleft lip and palate, we recommend preoperative cardiac consultation, careful examination and routine echocardiography for associated cardiac anomalies, as well as appropriate management and prophylactic antibiotic therapy for those with associated congenital heart anomaly.

    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.

    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.

    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.

    Kombucha tea (KT) is a popular health beverage and is used as an alternative therapy. KT is prepared by placing the kombucha culture in solution of tea and sugar and allowing to ferment. The inoculum is a fungus consisting of symbiotic colony of yeast and bacteria. KT is consumed in several countries and is believed to have prophylactic and therapeutic benefits in a wide variety of ailments, viz., intestinal disorders, arthritis, ageing and stimulation of immunological system. Though KT is used in several parts of the world its beneficial effects and adverse effects have not been scientifically evaluated. Since there are no animal toxicological data on KT, subacute oral toxicity study was carried out. Five groups of rats were maintained: (a) control group given tap water orally, (b) KT given 2 ml/kg orally, (c) plain tea (PT) given 2 ml/kg orally, (d) KT given in drinking water, 1% (v/v) and (e) PT given in drinking water, 1% (v/v). The rats were given this treatment daily for a period of 90 days. Weekly records of weight, feed intake, water intake and general behaviour were monitored. There was no significant difference in the growth of the animals as evidenced by the progressive body weight change. The organ to body weight ratio and histological evaluation did not show any toxic signs. The haematological and biochemical variables were within the clinical limits. The study indicates that rats fed KT for 90 days showed no toxic effects.

    Patients undergoing radiotherapy for head and neck cancer are at increased risk of developing oral candidiasis. The objective of this study was to investigate the clinical Candida mucositis and interruptions in radiotherapy in patients suffering from head and neck cancer, receiving fluconazole in comparison with a control group without specific prophylaxis. Eighty consecutive patients were randomized in a prospective double-blind trial of prophylactic oral fluconazole or treatment with the same drug when mycotic infections appeared. Adult head and neck cancer patients who were undergoing treatment with radiotherapy and/or chemotherapy, radiotherapeutic coverage of the entire oropharynx and oral cavity at least 3 cm anterior to the retromolar trigone and receiving a total dose of more than 6000 cGy and Karnofsky Performance Status (KPS) >70 were included in the study. Group A received radiation therapy plus fluconazole (Fluzole 100 mg/day) starting from the sixth irradiation session throughout the treatment; 40 patients in group B received the same baseline treatment, but were given fluconazole only when mycotic infections appeared. We evaluated 37 patients in group A and the first 37 patients were evaluated in group B. Three of the patients in group A (8.1%) and 14 of the patients in group B (37.8%) demonstrated clinical candidasis. Radiotherapy was interrupted in all of these patients. The differences between the two groups were statistically significant with respect to clinical candidiasis (P=0.005). The median discontinuation time was 5 days (range, 3-7 days) in group A and 7 days (range, 4-10 days) in group B. The median dose resulting in clinical candidiasis was 3200 cGy (range, 2200-5800 cGy) in all groups. In the fluconazole group it was 4200 cGy and in the control group 2800 cGy. These results suggest that patients undergoing head and neck radiation therapy are at risk of developing candidiasis and that fluconazole may be used to reduce the frequency of

    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

    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.

    and warn all oral contraceptive users of a potential reduction in efficacy during antibiotic therapy. These opinions are not evidence-based and rely heavily on one or two legal proceedings that cannot even be substantiated. On the other hand, there is one recently published legal proceeding in which the outcome was in favor of the oral surgeon. There is clearly a need for additional scientific research in oral contraceptive users that incorporates larger sample sizes, different time courses (prophylactic use versus standard 7-10 day use versus extended use), and different delivery systems (systemic administration versus local-controlled delivery) of antibiotic therapy. Though experts on this topic still recommend informing oral contraceptive users of the potential for a rare interaction, and for clinicians to advise them to employ additional barrier techniques of birth control during antibiotic therapy and for at least 1 week beyond the last dose [40], it is hoped that a set of guidelines regarding this controversy will eventually be published that is evidence-based, and not solely the results of anecdotal reports, expert opinions, and legal proceedings.

    Oral vaccines delivered as tablets offer a number of advantages over traditional parenteral-based vaccines including the ease of delivery, lack of needles, no need for trained medical personnel, and the ability to formulate into temperature-stable tablets. We have been evaluating an oral vaccine platform based on recombinant adenoviral vectors for the purpose of creating a prophylactic vaccine to prevent influenza, and have demonstrated vaccine efficacy in animal models and substantial immunogenicity in humans. These studies have evaluated monovalent vaccines to date. To protect against the major circulating A and B influenza strains, a multivalent influenza vaccine will be required. In this study, the immunogenicity of orally delivered monovalent, bivalent, trivalent, and quadrivalent vaccines was tested in ferrets and mice. The various vaccine combinations were tested by blending monovalent recombinant adenovirus vaccines, each expressing hemagglutinin from a single strain. Human tablet delivery was modeled in animals by oral gavage in mice and by endoscopic delivery in ferrets. We demonstrated minimal interference between the various vaccine vectors when used in combination and that the oral quadrivalent vaccine compared favorably to an approved trivalent inactivated vaccine. The quadrivalent vaccine presented here produced immune responses that we predict should be capable of providing protection against multiple influenza strains, and the platform should have applications to other multivalent vaccines.

    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.

    Hyperinsulinemia secondary to a poorly characterized disorder of insulin action is a feature of polycystic ovarian disease (PCOD). On the other hand, being generally admitted that opioids may play a role in glycoregulation and that opioid tone is altered in PCOD, an involvement of the opioids in determining the hyperinsulinemia of PCOD patients could be suggested. The aim of this study was to evaluate the effect of a chronic opioid blockade on insulin metabolism and peripheral insulin sensitivity in PCOD hyperinsulinemic patients. Twenty-three women with PCOD were studied. An oral glucose tolerance test (OGTT) and a clamp study were performed at baseline (during the follicular phase) and after 6 weeks of naltrexone administration (50 mg/d orally). Based on the insulinemic response to the OGTT, 16 women were classified as hyperinsulinemic and seven as normoinsulinemic. Naltrexone treatment significantly reduced fasting (P PCOD patients.

    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.

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

    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.

    2008-01-01

    Cancer patients under treatment of head and neck tumors as well as those under chemotherapy for hematologic cancers, such as lymphoma and leukemia, and those about to receive bone marrow grafts, do require preventive oral and dental care (prior to cancer treatment), as well as oral care during and after oncological treatment. Furthermore, chemo and radiotherapy-related adverse effects are also common in patients with other types of cancer, with an estimated frequency of 10 per cent in adjuvant chemotherapy (QT), 40 per cent in primary QT, 80 per cent in bone marrow transplantation, in which myeloablative regimens are introduced, and 100 per cent in head and neck radiotherapy, in which the targeted fields are those of the oral cavity. The dentist, specialized in dental oncology, works within the multidisciplinary team at the great centers of cancer treatment, contributing to improve the quality of life of these patients. The present review of literature and of the Guidelines for Management of Oral Complications of Chemotherapy and Head and Neck Radiation (US National Cancer Institute) aims to inform the clinical oncologist, the radio therapist, and other professionals about the resources available in Oral Supportive Therapy in both the prevention and managements of such complications.

    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.

The aim of this study was to assess the effect of melatonin in the proliferation of neural progenitors, melatonin concentration, and antiapoptotic proteins in the hippocampus of adult mice exposed to 96 h REM sleep deprivation (REMSD prophylactic administration of melatonin for 14 days. Material and Methods. Five groups of Balb/C mice were used: (1 control, (2 REMSD, (3 melatonin (10 mg/kg plus REMSD, (4 melatonin and intraperitoneal luzindole (once a day at 5 mg/kg plus REMSD, and (5 luzindole plus REMSD. To measure melatonin content in hippocampal tissue we used HPLC. Bcl-2 and Bcl-xL proteins were measured by Western Blot and neurogenesis was determined by injecting 5-bromo-2-deoxyuridine (BrdU and BrdU/nestin expressing cells in the subgranular zone of the dentate gyrus were quantified by epifluorescence. Results. The melatonin-treated REMSD group showed an increased neural precursor in 44% with respect to the REMSD group and in 28% when contrasted with the control group (P<0.021. The melatonin-treated REMSD group also showed the highest expression of Bcl-2 and Bcl-xL as compared to the rest of the groups. Conclusion. The exogenous administration of melatonin restores the tissue levels of sleep-deprived group and appears to be an efficient neuroprotective agent against the deleterious effects of REMSD.

    The objective of this study was to evaluate the prophylactic efficacy of co-oral administration of vitamin B 12 with vitamin C against radiation induced haematological and biochemical alterations in male albino rats. Male albino rats were divided into six groups (n=8). Group 1: rats were kept as control, Group 2; rats received orally vita-min B 12 (2000μgkg -1 ). Group 3; rats received Vitamin B 12 with Vitamin C (500mgkg -1 ). Group 4; rats whole body exposed to 7Gy of gamma rays. Group 5; rats received vitamin B 12 for 21 successive days before irradiation. Group 6; rats received Vitamin B 12 with Vitamin C for 21 successive days before irradiation. Animals were sacrificed the third day post irradiation. The oral administration of Vitamin B 12 with or with-out Vitamin C enhanced the recovery from radiation-induced haemopoietic injury and some biochemical changes demonstrated by a significant increase (p0.05>) of WBCs, RBCs and Platelets count, Hb content, Hct%, serum erythropoietin and iron levels and a significant reduction (p0.05>) of serum homocysteine level (Hcy), creatine kinase (CK-MB) and lactate dehydrogenase (LDH) activities compared to their respective values in irradiated rats. Improvement of oxidative stress in heart and spleen tissues denoted by a significant decrease in lipid peroxidation (MDA) and a significant increase in glutathione (GSH) content was recorded also. The co-oral administration of vitamin B 12 with vitamin C has no effect on the prophylactic efficacy of vitamin B 12

    Pregnancy is a natural process that may create some changes in different parts of the body including the oral cavity. These changes will lead to oral diseases if enough and timely care of oral cavity is not taken. Women may experience increased gingivitis or pregnancy gingivitis beginning in the second or third month of pregnancy that increases in severity throughout the duration of pregnancy. To motivate the patient toward oral health and implement the needed prophylactic measures, a longitudinal study was planned to observe the effect of oral health education during pregnancy on knowledge, attitude, practice, oral health status, and treatment needs (TNs) of pregnant women belonging to different socioeconomic groups. A longitudinal study was conducted among 112 pregnant women belonging to different socioeconomic groups to assess the effect of oral health education on knowledge, attitude, practice, oral health status, and TNs. The demographic details, knowledge, attitude, and practice of pregnant women, and oral health status were collected through a predesigned questionnaire by a principal investigator through an interview. Oral health examination was carried out to assess oral health status using revised World Health Organization Proforma 1997, and oral health education was given through PowerPoint presentation to the participants in local language, i.e., Marathi, after collecting the baseline data. Reinforcement of oral health education and blanket referral was done at 14th week, and follow-up data were collected at 28th week of gestation. The demographic details, such as age, sex, education, occupation, income, and the questions based on knowledge, attitude, and practice among participants were analyzed using number, percentage, and mean. At baseline, knowledge was limited, attitude was positive, while the practice was poor regarding oral health care during pregnancy in pregnant women belonging to different socioeconomic groups.

    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).

    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).

    Endogenous opioids have complex social effects that may depend on specific receptor actions and vary depending on the "stage" of social behavior (e.g., seeking vs. responding to social stimuli). We tested the effects of a nonspecific opioid antagonist, naltrexone (NTX), on social processing in humans. NTX is used to treat alcohol and opiate dependence, and may affect both mu and kappa-opioid systems. We assessed attention ("seeking"), and subjective and psychophysiological responses ("responding") to positive and negative social stimuli. Based on literature suggesting mu-opioid blockade impairs positive social responses, we hypothesized that NTX would decrease responses to positive social stimuli. We also tested responses to negative stimuli, which might be either increased by NTX's mu-opioid effects or decreased by its kappa-opioid effects. Thirty-four healthy volunteers received placebo, 25 mg, or 50 mg NTX across three sessions under double-blind conditions. At each session, participants completed measures of attention, identification, and emotional responses for emotional faces and scenes. NTX increased attention to emotional expressions, slowed identification of sadness and fear, and decreased ratings of arousal for social and nonsocial emotional scenes. These findings are more consistent with anxiolytic kappa-antagonist than mu-blocking effects, suggesting effects on kappa receptors may contribute to the clinical effects of NTX.

    Infantile colic, gastroesophageal reflux, and constipation are the most common functional gastrointestinal disorders that lead to referral to a pediatrician during the first 6 months of life and are often responsible for hospitalization, feeding changes, use of drugs, parental anxiety, and loss of parental working days with relevant social consequences. To investigate whether oral supplementation with Lactobacillus reuteri DSM 17938 during the first 3 months of life can reduce the onset of colic, gastroesophageal reflux, and constipation in term newborns and thereby reduce the socioeconomic impact of these conditions. A prospective, multicenter, double-masked, placebo-controlled randomized clinical trial was performed on term newborns (age hospitalizations, visits to a pediatric emergency department for a perceived health emergency, pharmacologic interventions, and loss of parental working days. In total, 589 infants were randomly allocated to receive L reuteri DSM 17938 or placebo daily for 90 days. Prophylactic use of probiotic. Reduction of daily crying time, regurgitation, and constipation during the first 3 months of life. Cost-benefit analysis of the probiotic supplementation. At 3 months of age, the mean duration of crying time (38 vs 71 minutes; P < .01), the mean number of regurgitations per day (2.9 vs 4.6; P < .01), and the mean number of evacuations per day (4.2 vs 3.6; P < .01) for the L reuteri DSM 17938 and placebo groups, respectively, were significantly different. The use of L reuteri DSM 17938 resulted in an estimated mean savings per patient of €88 (US $118.71) for the family and an additional €104 (US $140.30) for the community. Prophylactic use of L reuteri DSM 17938 during the first 3 months of life reduced the onset of functional gastrointestinal disorders and reduced private and public costs for the management of this condition. clinicaltrials.gov Identifier: NCT01235884.

    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.

    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.

    The aim was to study oral health and oromotor function in individuals with rare diseases. A disease is defined as rare when it affects no more than 100 individuals per million population and leads to a marked degree of disability. An affected nervous or musculoskeletal system, cognitive impairment, neuropsychiatric disorders and craniofacial malformations are common in rare diseases and may all be risk factors for oral health and oromotor function. In 1996-2008, 1,703 individuals with 169 rare diseases, aged 3-67 years, answered a questionnaire about general health, oral health and orofacial function and 1,614 participated in a clinical examination. A control group of 135 healthy children, aged 3-14 years, was also included in the study. Oral health was examined by a dentist and oromotor function by a speech-language pathologist. The participants with rare diseases were recruited via family programmes, referrals to the clinic and research projects, while the controls were randomly selected from a Swedish municipality. In the diagnosis group, 40% had moderate or severe problems coping with dental treatment, 43% were receiving specialised dental care. Difficulties related to tooth brushing were common compared with the controls. Approximately two thirds of the study group and the control group were caries free. Frontal open bite, long face and high palate were common in individuals with rare diseases compared with controls. Oromotor impairment was a frequent finding (43%) and was absent among the controls. There was a significant correlation between oromotor impairment and certain structural deviations and oral-health issues. Compared with healthy controls, individuals with rare diseases often have difficulty coping with dental treatment and managing tooth brushing. Dysmorphology and oromotor dysfunction are frequent findings in this population and they often require extra prophylactic dental care and access to specialised dental care in order to prevent oral disease.

    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.

  1. Oral Iron Prophylaxis in Pregnancy: Not Too Little and Not Too Much!

    Full Text Available An adequate supply of iron is essential for normal development of the fetus and newborn child. Iron deficiency and iron deficiency anemia (IDA during pregnancy increase the risk of preterm birth and low birth weight. Iron is important for development of the fetal brain and cognitive abilities of the newborn. Children born to iron-deficient mothers will start their lives suffering from iron deficiency or even IDA. Oral iron prophylaxis to pregnant women improves iron status and prevents development of IDA. The Danish National Board of Health has since 1992 recommended prophylactic oral iron supplements to all pregnant women and the currently advocated dose is 40–50 mg ferrous iron taken between meals from 10 weeks gestation to delivery. However, 30–40 mg ferrous iron is probably an adequate dose in most affluent societies. In developed countries, individual iron prophylaxis guided by iron status (serum ferritin has physiological advantages compared to general iron prophylaxis. In contrast, in most developing countries, general iron prophylaxis is indicated, and higher doses of oral iron, for example, 60 mg ferrous iron or even more should be recommended, according to the present iron status situation in the specific populations of women of fertile age and pregnant women.

    Oral squamous cell carcinoma (OSCC) has a high incidence of cervical micrometastases and sometimes metastasizes contralaterally because of the rich lymphatic intercommunications relative to submucosal plexus of oral cavity that freely communicate across the midline, and it can facilitate the spread of neoplastic cells to any area of the neck consequently. Clinical and histopathologic factors continue to provide predictive information to contralateral neck metastases (CLNM) in OSCC, which determine prophylactic and adjuvant treatments for an individual patient. This review describes the predictive value of clinical-histopathologic factors, which relate to primary tumor and cervical lymph nodes, and surgical dissection and adjuvant treatments. In addition, the indications for elective contralateral neck dissection and adjuvant radiotherapy (aRT) and strategies for follow-up are offered, which is strongly focused by clinicians to prevent later CLNM and poor prognosis subsequently.

    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.

    Pregnancy may pose an increased risk for the development of caries and other oral health problems. Continuous screening of oral health status, implementing appropriate preventive measures (particularly oral hygiene, healthy diet plans and education) is of paramount importance not only for oral health but also for the general health status of the future mother and her offspring. EFFECTS OF FOOD ON CARIES DEVELOPMENT: Caries prevention through healthy diet implicates the reduction in frequency and amount of intake of cariogenic food, above all ofrefined carbohydrates, i.e. sugars and sweets. Foods known to have caries-prophylactic effects should predominate in healthy diet plans. They mainly include solid foods, which have mechanical effects on teeth cleaning, as well as foods providing sufficient amounts of vitamins (A, C, D) and a variety of elements and compounds (calcium, phosphates, fluorides) favoring the preservation and remineralization of tooth structures. EDUCATION OF PREGNANT WOMEN ON HEALHY DEIT: In accomplishing these goals, education and direct positive communication between the educator and the pregnant woman play a crucial role. Educative approach is always individual and determined by the patient's specific cultural and socioeconomic features and status, as well as her habits, motivation and willingness to accept relevant recommendations. Accomplishing the aforementioned goals requires the appropriate organization and professional competence within the preventive dental service and its close cooperation with the relevant medical institutions and social support in the framework of public health protection. Preserving of oral health during pregnancy is predominantly influenced by the following factors: 1) healthy diet, 2) oral hygiene, 3) patients' education, 4) regular control of oral health, 5) appropriate organization of dental services and 6) community engagement.

    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).

    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.

  13. 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.

    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.

  4. Prophylactic antibiotics for penetrating abdominal trauma.

    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.

    Human rotavirus (RV) infection is a leading cause of dehydrating diarrhea in infants and young children worldwide. Since therapeutic approaches to RV gastroenteritis are limited to alleviation of dehydration with oral rehydration solutions, more direct approaches to palliate symptoms of RV gastroenteritis are required. Treatments with probiotics have been increasingly recognized as alternative safe and low cost treatments for moderate infectious diarrhea. In this study, Bifidobacterium bifidum G9-1 (BBG9-1), which has been used as an intestinal drug for several decades, was shown to have a remarkable protective effect against RV gastroenteritis in a suckling mice model. As well as prophylactic oral administration of BBG9-1 from 2 days before RV infection, therapeutic oral administration of BBG9-1 from 1 day after RV infection significantly alleviated RV-induced diarrhea. Therapeutic administration of BBG9-1 reduced various types of damage in the small intestine, such as epithelial vacuolization and villous shortening, and significantly diminished the infectious RV titer in mixtures of cecal contents and feces. It was also shown that therapeutic administration of BBG9-1 significantly increased the number of acidic mucin-positive goblet cells and the gene expression of mucosal protective factors including MUC2, MUC3, MUC4, TGFβ1 and TFF3 in the small intestine. This led to alleviation of low gut permeability shown as decreased gene expression levels of occludin, claudin-1 and villin-1 after RV infection. Furthermore, in the small intestine, therapeutic administration of BBG9-1 significantly palliated the decreased gene expression of SGLT-1, which plays an important role in water absorption. In the large intestine, administered BBG9-1 was shown to replicate to assimilate undigested nutrients, resulting in normalization of the abnormally high osmotic pressure. These results suggested that water malabsorption caused by RV infection was alleviated in mice administered

    Liver cancer remains one of the severe lethal malignancies worldwide and hepatocellular carcinoma (HCC) is the most common form. The current study was designed to evaluate the prophylactic role of the fruit of Averrhoa carambola (star fruit or Kamrak) on diethylnitrosamine- (DENA-) induced (15 mg/kg b.wt.; single i.p. injection) and CCl4-promoted (1.6 g/kg b.wt. in corn oil thrice a week for 24 weeks) liver cancer in Swiss albino mice. Administration of ACE was made orally at a dose of 25 mg/kg b.wt/day for 5 consecutive days and it was withdrawn 48 hrs before the first administration of DENA (preinitiational stage). CCl4 was given after 2 weeks of DENA administration. A cent percent tumor incidence was noted in carcinogen treated animals while ACE administration resulted in a considerable reduction in tumor incidence, tumor yield, and tumor burden. Further, ACE treatment brings out a significant reduction in lipid peroxidation (P carambola against hepatocellular carcinoma in mice; therefore, it could be employed for the further screening as a good chemopreventive natural supplement against cancer.

    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.

    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.

    To evaluate the conversion of opioid-experienced patients with chronic moderate-to-severe pain to extended-release morphine sulfate with sequestered naltrexone hydrochloride (MSN) using a standardized conversion guide. This open-label, single-arm study was conducted in 157 primary care centers in the United States. A total of 684 opioid-experienced adults with chronic moderate-to-severe pain were converted to oral administration of MSN from transdermal fentanyl and oral formulations of hydrocodone, hydromorphone, methadone, oxycodone, oxymorphone, and other morphine products using a standardized conversion guide. The primary endpoint was the percentage of patients achieving a stable MSN dose within a 6-week titration phase. Secondary endpoints included duration of time to stable dose, number of titration steps, safety and efficacy measures, and investigator assessment of conversion guide utility. Of the 684 patients, 51.3% were converted to a stable dose of MSN (95% confidence interval: 47.5%, 55.1%). The mean (standard deviation) number of days to stable dose was 20 (8.94), and number of titration steps to stable dose was 2.4 (1.37). The majority of adverse events were mild/moderate and consistent with opioid therapy. Mean pain scores at stable dose decreased from baseline. Investigators were generally satisfied with the conversion guide and, in 94% of cases, reported they would use it again. Conversion to MSN treatment using the standardized MSN conversion guide was an attainable goal in approximately half of the population of opioid-experienced patients with chronic moderate-to-severe pain. Investigators found the guide to be a useful tool to assist conversion of opioid-experienced patients to MSN.

    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.

    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.

    The importance of HPV in world healthy is high, in fact high-risk HPV types contribute significantly to viral associated neoplasms. In this article we will analyze vary expression of HPV in oral cavity both benign and malignant, their prevalence and the importance in early diagnosis and prevention. The classical oral lesions associated with human papillomavirus are squamous cell papilloma, condyloma acuminatum, verruca vulgaris and focal epithelial hyperplasia. Overall, HPV types 2, 4, 6, 11, 13 and 32 have been associated with benign oral lesions while HPV types 16 and 18 have been associated with malignant lesions, especially in cancers of the tonsils and elsewhere in the oropharynx. Transmission of the virus can occur with direct contact, genital contact, anal and oral sex; latest studies suggest a salivary transmission and from mother to child during delivery. The number of lifetime sexual partners is an important risk factor for the development of HPV-positive head-neck cancer. Oral/oropharyngeal cancer etiologically associated with HPV having an increased survival and a better prognostic (85%-90% to five years). There is no cure for the virus. There are two commercially available prophylactic vaccines against HPV today: the bivalent (16 and 18) Cervarix® and the tetravalent (6, 11, 16 and 18) Gardasil® and new vaccine Gardasil 9 (6, 11, 16, 18, 31, 33, 45, 52, 58) was approved in the United States. To be effective, such vaccination should start before "sexual puberty". The vaccine could be an important preventive strategy, in fact the scientific community is in agreement on hypothesis that blocking the contagion it may also limit the distance complications as the oropharyngeal cancer.

    Background: The prevention of contrast-induced acute kidney injury (AKI) after coronary computed tomography angiography (CCTA) is important because patients referred for CCTA often need further contrast exposure such as an invasive coronary angiography. We aimed to examine the effects of oral volume intake on renal function in patients with preserved renal function referred for CCTA. Methods: We enrolled 180 patients who were referred for CCTA. The serum creatinine (SCr) and estimated glomerular filtration rate (eGFR) levels were measured before, 24 h, and a mean of 4.8 days after CCTA. The amount of unrestricted oral fluid intake for 24 h was checked. The patients were divided into two groups: 106 subjects with a rise in SCr after CCTA (group A); and 74 without (group B). Results: Significant correlations were observed between the amount of oral fluid intake and the percentage changes in SCr (%SCr) (r = -0.66, p < 0.0001) as well as the absolute changes in eGFR (ΔeGFR) (r = 0.65, p < 0.0001). The percentage of patients showing hemoglobin-A1c (HbA1c) ≥ 6.5% was greater in group A than in group B (29% vs. 18%, p < 0.001). Patients with HbA1c ≥ 6.5% showed higher %SCr and lower ΔeGFR compared to those without it. Multiple regression analysis revealed that the amount of oral fluid intake was the only independent predictor for a rise in SCr (β = -0.731, p < 0.0001). Conclusion: Oral volume intake after CCTA is a very simple but important prophylactic procedure for contrast-induced AKI especially in diabetic patients.

    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 The chemotherapeutic agent paclitaxel (PTX causes peripheral neuropathy as a major dose-limiting side effect, and this peripheral neuropathy is difficult to control. Our previous report showed that prophylactic repetitive administration of goshajinkigan (牛車腎氣丸 niú chē shèn qì wán, but not hachimijiogan (八味地黃丸 bā wèi dì huáng wán, which lacks two of the constituents of goshajinkigan, inhibited PTX-induced mechanical allodynia in mice. Thus, the herbal medicines Plantaginis Semen (車前子 chē qián zǐ or Achyranthis Radix (牛膝 niú xī may contribute to the inhibitory action of goshajinkigan on the exacerbation of PTX-induced mechanical allodynia [Andoh et al, J. Tradit. Complement. Med. 2014; 4: 293–297]. Therefore, in this study, we examined whether an extract of Plantaginis Semen (EPS or Achyranthis Radix (EAR would relieve PTX-induced mechanical allodynia in mice. A single intraperitoneal injection of PTX caused mechanical allodynia, which peaked on day 14 after injection. Repetitive oral administration of EPS, but not EAR, starting from the day after PTX injection significantly inhibited the exacerbation of PTX-induced mechanical allodynia. Repetitive intraperitoneal injection of aucubin, one of the main components of EPS, starting from the day after PTX injection also significantly reduced PTX-induced mechanical allodynia. However, repetitive intraperitoneal injection of geniposide acid (a precursor of aucubin or catalpol (a metabolite of aucubin did not prevent the exacerbation of mechanical allodynia. These results suggest that prophylactic administration of EPS is effective for preventing the exacerbation of PTX-induced allodynia. Aucubin may contribute to the inhibitory action of EPS on the exacerbation of PTX-induced allodynia.

    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.

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.

    In a double-blind trial comprising 66 patients we assessed the effect of metronidazole-nystatin vagitories on the prevention of bacterial vaginosis (BV) in women using IUD as a contraceptive method after an initial oral single dose of 2.0 g metronidazole and 7 days of intravaginal metronidazole-nystatin or placebo treatment. The prophylactic treatment consisted of metronidazole-nystatin or placebo vagitories applied at bedtime for 3 days after menstruation over 6 consecutive menstrual periods. The patients were randomized in two study groups: a treatment group of 32 patients (group A) and a placebo group of 34 patients (group B). The overall objective cure rate after the initial treatment was 97% in group A and 91% in group B. After 6 months of follow-up, the overall cumulative objective cure rate in group A was 100%, and 76% in group B. The single-dose oral treatment was well tolerated and no notable side effects were recorded.

    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.

    Full Text Available Opiates have been implicated in learned helplessness (LH, a phenomenon known to be related to opiate stress-induced analgesia (SIA. In the present study, we investigated the role of opiates in the induction of LH and SIA under different conditions. Adult female Wistar rats were trained either by receiving 60 inescapable 1-mA footshocks (IS group, N = 114 or by confinement in the shock box (control or NS group, N = 92. The pain threshold of some of the animals was immediately evaluated in a tail-flick test while the rest were used 24 h later in a shuttle box experiment to examine their escape performance. The opiate antagonist naltrexone (0 or 8 mg/kg, ip and the previous induction of cross-tolerance to morphine by the chronic administration of morphine (0 or 10 mg/kg, sc, for 13 days were used to identify opiate involvement. Analysis of variance revealed that only animals in the IS group demonstrated antinociception and an escape deficit, both of which were resistant to the procedures applied before the training session. However, the escape deficit could be reversed if the treatments were given before the test session. We conclude that, under our conditions, induction of the LH deficit in escape performance is not opiate-mediated although its expression is opiate-modulated

    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.

    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.

    There are currently no commonly used or easily accessible 'biomarkers' of hedonic eating. Physiologic responses to acute opioidergic blockade, indexed by cortisol changes and nausea, may represent indirect functional measures of opioid-mediated hedonic eating drive and predict weight loss following a mindfulness-based intervention for stress eating. In the current study, we tested whether cortisol and nausea responses induced by oral ingestion of an opioidergic antagonist (naltrexone) correlated with weight and self-report measures of hedonic eating and predicted changes in these measures following a mindfulness-based weight loss intervention. Obese women (N = 88; age = 46.7 ± 13.2 years; BMI = 35.8 ± 3.8) elected to complete an optional sub-study prior to a 5.5-month weight loss intervention with or without mindfulness training. On two separate days, participants ingested naltrexone and placebo pills, collected saliva samples, and reported nausea levels. Supporting previous findings, naltrexone-induced cortisol increases were associated with greater hedonic eating (greater food addiction symptoms and reward-driven eating) and less mindful eating. Among participants with larger cortisol increases (+1 SD above mean), mindfulness participants (relative to control participants) reported greater reductions in food addiction symptoms, b = -0.95, SE(b) = 0.40, 95% CI [-1.74, -0.15], p = .021. Naltrexone-induced nausea was marginally associated with reward-based eating. Among participants who endorsed naltrexone-induced nausea (n = 38), mindfulness participants (relative to control participants) reported greater reductions in food addiction symptoms, b = -1.00, 95% CI [-1.85, -0.77], p = .024, and trended toward reduced reward-based eating, binge eating, and weight, post-intervention. Single assessments of naltrexone-induced cortisol increases and nausea responses may be useful time- and cost-effective biological markers to

    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.

    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.

    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

    Probiotics are live bacteria that confer health benefits to the host physiology. Although protective role of probiotics have been reported in diverse diseases, no information is available whether probiotics can modulate neuromuscular immune disorders. We have recently demonstrated that IRT5 probiotics, a mixture of 5 probiotics, could suppress diverse experimental disorders in mice model. In this study we further investigated whether IRT5 probiotics could modulate the progression of experimental autoimmune myasthenia gravis (EAMG). Myasthenia gravis (MG) is a T cell dependent antibody mediated autoimmune disorder in which acetylcholine receptor (AChR) at the neuromuscular junction is the major auto-antigen. Oral administration of IRT5 probiotics significantly reduced clinical symptoms of EAMG such as weight loss, body trembling and grip strength. Prophylactic effect of IRT5 probiotics on EMAG is mediated by down-regulation of effector function of AChR-reactive T cells and B cells. Administration of IRT5 probiotics decreased AChR-reactive lymphocyte proliferation, anti-AChR reactive IgG levels and inflammatory cytokine levels such as IFN-γ, TNF-α, IL-6 and IL-17. Down-regulation of inflammatory mediators in AChR-reactive lymphocytes by IRT5 probiotics is mediated by the generation of regulatory dendritic cells (rDCs) that express increased levels of IL-10, TGF-β, arginase 1 and aldh1a2. Furthermore, DCs isolated from IRT5 probiotics-fed group effectively converted CD4+ T cells into CD4+Foxp3+ regulatory T cells compared with control DCs. Our data suggest that IRT5 probiotics could be applicable to modulate antibody mediated autoimmune diseases including myasthenia gravis. PMID:23284891

    Hypothalamic obesity, a treatment-resistant condition common to survivors of craniopharyngioma (CP), is strongly associated with a poor quality of life in this population. Oxytocin (OT), a hypothalamic neuropeptide, has been shown to play a role in the regulation of energy balance and to have anorexigenic effects in animal studies. Naltrexone (NAL), an opiate antagonist, has been shown to deter hedonic eating and to potentiate OT's effects. In this parent-observed study, we tested the administration of intranasal OT for 10 weeks (phase 1), followed by a combination of intranasal OT and NAL for 38 weeks (phase 2) in a 13-year-old male with confirmed hypothalamic obesity and hyperphagia post-CP resection. Treatment resulted in 1) reduction in body mass index (BMI) z score from 1.77 to 1.49 over 10 weeks during phase 1; 2) reduction in BMI z score from 1.49 to 0.82 over 38 weeks during phase 2; 3) reduced hyperphagia during phases 1 and 2; 4) continued hedonic high-carbohydrate food-seeking in the absence of hunger during phases 1 and 2; and 5) sustained weight reduction during decreased parental monitoring and free access to unlocked food in the home during the last 10 weeks of phase 2. This successful intervention of CP-related hypothalamic obesity and hyperphagia by OT alone and in combination with NAL is promising for conducting future studies of this treatment-recalcitrant form of obesity.

    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 the present study was to evaluate the skin permeation of naltrexone (NTX) under the influence of a pulsed electromagnetic field (PEMF). The permeation of NTX across human epidermis and a silicone membrane in vitro was monitored during and after application of the PEMF and compared to passive application. Enhancement ratios of NTX human epidermis permeation by PEMF over passive diffusion, calculated based on the AUC of cumulative NTX permeation to the receptor compartment verses time for 0-4 h, 4-8 h, and over the entire experiment (0-8 h) were 6.52, 5.25, and 5.66, respectively. Observation of the curve indicated an initial enhancement of NTX permeation compared to passive delivery whilst the PEMF was active (0-4 h). This was followed by a secondary phase after termination of PEMF energy (4-8 h) in which there was a steady increase in NTX permeation. No significant enhancement of NTX penetration across silicone membrane occurred with PEMF application in comparison to passively applied NTX. In a preliminary experiment PEMF enhanced the penetration of 10 nm gold nanoparticles through the stratum corneum as visualized by multiphoton microscopy. This suggests that the channels through which the nanoparticles move must be larger than the 10 nm diameter of these rigid particles.

    Bronchiectasis is a chronic inflammatory disease characterised by a recurrent cycle of respiratory bacterial infections associated with cough, sputum production and impaired quality of life. Antibiotics are the main therapeutic option for managing bronchiectasis exacerbations. Evidence suggests that inhaled antibiotics may be associated with more effective eradication of infective organisms and a lower risk of developing antibiotic resistance when compared with orally administered antibiotics. However, it is currently unclear whether antibiotics are more effective when administered orally or by inhalation. To determine the comparative efficacy and safety of oral versus inhaled antibiotics in the treatment of adults and children with bronchiectasis. We identified studies through searches of the Cochrane Airways Group's Specialised Register (CAGR), which is maintained by the Information Specialist for the group. The Register contains trial reports identified through systematic searches of bibliographic databases including the Cochrane Central Register of Controlled Trials (CENTRAL), MEDLINE, Embase, CINAHL, AMED, and PsycINFO, and handsearching of respiratory journals and meeting abstracts. We also searched ClinicalTrials.gov and the WHO trials portal. We searched all databases in March 2018 and imposed no restrictions on language of publication. We planned to include studies which compared oral antibiotics with inhaled antibiotics. We would have considered short-term use (less than four weeks) for treating acute exacerbations separately from longer-term use as a prophylactic (4 weeks or more). We would have considered both intraclass and interclass comparisons. We planned to exclude studies if the participants received continuous or high-dose antibiotics immediately before the start of the trial, or if they have received a diagnosis of cystic fibrosis (CF), sarcoidosis, active allergic bronchopulmonary aspergillosis or active non-tuberculous Mycobacterial infection

    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.

    During migraine, capsaicin-sensitive trigeminal sensory nerves release calcitonin gene-related peptide (CGRP), resulting in cranial vasodilatation and central nociception. Moreover, 5-HT is involved in the pathophysiology of migraine and depression. Interestingly, some limited lines of evidence suggest that fluoxetine may be effective in migraine prophylaxis, but the underlying mechanisms are uncertain. Hence, this study investigated the canine external carotid vasodilator responses to capsaicin, α-CGRP and acetylcholine before and after acute and chronic oral treatment with fluoxetine. Forty-eight vagosympathectomised male mongrel dogs were prepared to measure blood pressure, heart rate and external carotid blood flow. The thyroid artery was cannulated for infusions of agonists. In 16 of these dogs, a spinal cannula was inserted (C1-C3) for infusions of 5-HT. The external carotid vasodilator responses to capsaicin, α-CGRP and acetylcholine remained unaffected after intracarotid or i.v. fluoxetine. In contrast, the vasodilator responses to capsaicin, but not those to α-CGRP or acetylcholine, were inhibited after chronic oral treatment with fluoxetine (300 µg/kg; for 90 days) or intrathecal 5-HT. Chronic oral fluoxetine inhibited capsaicin-induced external carotid vasodilatation, and this inhibition could partly explain its potential prophylactic antimigraine action. © International Headache Society 2015.

    The purpose was to evaluate prevention of oral mucositis (OM) using chlorhexidine compared with placebo and with oral cooling (cryotherapy) during fluorouracil (5-FU)-based chemotherapy in gastrointestinal (GI) cancer. Patients with previously untreated GI cancer receiving bolus 5-FU/leucovorin chemotherapy were randomized to chlorhexidine mouthrinse 3 times a day for 3 weeks (Arm A), double-blind placebo (normal saline) with the same dose and frequency (Arm B), or cryotherapy with crushed ice 45 minutes during chemotherapy (Arm C). Patients self-reported on severity (CTC-grading) and duration of OM. Among 225 patients randomized, 206 answered the questionnaire (70, 64, and 63 patients in Arms A, B, and C, respectively) and were well balanced with respect to diagnoses, stage, age, sex, smoking habits, and performance status. Mucositis grade 3-4 occurred more frequently in Arm B (33%) than in A (13%, Pcryotherapy. The latter is easy and inexpensive but has limited use, as it is drug- and schedule-dependent. The current study is the first double-blind randomized evaluation of prophylactic chlorhexidine in a large adult patient population with solid tumors receiving highly OM-inducing chemotherapy. A role for chlorhexidine in the prevention of OM is suggested, which should be evaluated further.

However, the role of administration frequency relative to other treatment attributes in determining preferences for prophylactic hemophilia treatment regimens is not well understood. Aim: To identify the relative importance of frequency of administration, efficacy, and other treatment characteristics among candidates for prophylactic treatment for hemophilia A and B. Method: An Internet survey was conducted among hemophilia patients and the parents of pediatric hemophilia patients in Australia, Canada, and the US. 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.

    This study aims to compare the efficacy of orally administered Saccharomyces boulardii versus nystatin in prevention of fungal colonization and invasive fungal infections in very low birth weight infants. A prospective, randomized comparative study was conducted in preterm infants with a gestational age of ≤ 32 weeks and birth weight of ≤ 1,500 g. They were randomized into two groups, to receive S. boulardii or nystatin. Skin and stool cultures were performed for colonization and blood cultures for invasive infections, weekly. A total of 181 infants were enrolled (S. boulardii group, n = 91; nystatin group, n = 90). Fungal colonization of the skin (15.4 vs 18.9 %, p = 0.532) and the stool (32.2 vs 27 %, p = 0.441) were not different between the probiotic and nystatin groups. Two patients had Candida-positive blood culture in the nystatin group whereas none in the probiotic group. Feeding intolerance, clinical sepsis, and number of sepsis attacks were significantly lower in the probiotics group than in the nystatin group. Prophylactic S. boulardii supplementation is as effective as nystatin in reducing fungal colonization and invasive fungal infection, more effective in reducing the incidence of clinical sepsis and number of sepsis attacks and has favorable effect on feeding intolerance.

    The aim of this study was to assess and observe the oral hygiene and gingival condition in patients before and after fixed prosthodontic therapy through a 12-month period in combination with oral hygiene instructions. It was also analysed how factors, such as type of fixed prosthodontic appliance, constructive material, the position of a fixed partial denture (FPD) in the mouth, age and gender influenced oral hygiene. The dental arches were divided into three segments each and teeth and gingiva were examined using the Plaque and Gingiva Index by Silness and Löe, and for the mineralized deposits assessment the Calculus Index by Green and Vermillion was employed. The preliminary examination was conducted before the prosthodontic therapy, and the reexaminations were carried out 14 days, 1, 6 and 12 months after crown and/or FPD placement. A total of 93 subjects from the original study group of 146 patients attended all clinical examinations, while the rest was excluded. The sample consisted of 60 women, 33 men at age between 21 and 95 (average 51.8). A total of 39 patients had single crowns (C), 50 FPDs and 5 C+FPD. The frequency of plaque found during the preliminary visit was higher than that found in the other periods (p oral hygiene levels than patients with FPDs or C+FPDs (p = 0.001). Our results revealed no significant difference in oral hygiene status among patients with FPDs made of different materials (p = 0.083). The worst hygiene levels were found in patients with fixed prosthodontic appliances in both jaws (p = 0.012). Younger patients showed better hygiene levels than the older ones (p = 0.002). Our research showed that appropriate educational and motivational measures can lead to improved oral hygiene, even after FPD placement. Presumably, the oral health in a group of adult patients can be kept acceptable by providing a prophylactic oral hygiene program.

    SM-8668 (Sch 39304) is a new oral antifungal agent which we evaluated in comparison with fluconazole in various fungal infection models. The prophylactic effect of SM-8668 was excellent against systemic candidiasis, aspergillosis, and cryptococcosis in mice. The 50% effective dose for SM-8668 was assessed at 10 days after infection and was 0.18, 3.7, and 5.9 mg/kg (body weight), respectively, for the above-mentioned fungal diseases. Fluconazole was about four times less effective than SM-8668 against systemic candidiasis and was only slightly effective at doses of 80 and 25 mg/kg against systemic aspergilosis and cryptococcosis, respectively. SM-8668 was also about four to eight times more active than fluconazole against vaginal candidiasis in rats and against dermatophytic infection in guinea pigs. In addition, topical SM-8668 was as effective as topical miconazole or tioconazole against skin mycosis in guinea pigs. After oral administration, SM-8668 showed a maximum concentration in serum similar to that of fluconazole in both mice and rats, but the elimination half-life and area under the serum concentration-time curve for SM-8668 were twice those for fluconazole.

    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.

    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.

    Criminal justice-involved individuals are highly susceptible to opioid relapse and overdose-related deaths. In a recent randomized trial, we demonstrated the effectiveness of extended-release naltrexone (XR-NTX; Vivitrol ® ) in preventing opioid relapse among criminal justice-involved US adults with a history of opioid use disorder. The cost of XR-NTX may be a significant barrier to adoption. Thus, it is important to account for improved quality of life and downstream cost-offsets. Our aims were to (1) estimate the incremental cost per quality-adjusted life-year (QALY) gained for XR-NTX versus treatment as usual (TAU) and evaluate it relative to generally accepted value thresholds; and (2) estimate the incremental cost per additional year of opioid abstinence. Economic evaluation of the aforementioned trial from the taxpayer perspective. Participants were randomized to 25 weeks of XR-NTX injections or TAU; follow-up occurred at 52 and 78 weeks. Five study sites in the US Northeast corridor. A total of 308 participants were randomized to XR-NTX (n = 153) or TAU (n = 155). Incremental costs relative to incremental economic and clinical effectiveness measures, QALYs and abstinent years, respectively. The 25-week cost per QALY and abstinent-year figures were $162 150 and $46 329, respectively. The 78-week figures were $76 400/QALY and $16 371/abstinent year. At 25 weeks, we can be 10% certain that XR-NTX is cost-effective at a value threshold of $100 000/QALY and 62% certain at $200 000/QALY. At 78 weeks, the cost-effectiveness probabilities are 59% at $100 000/QALY and 76% at $200 000/QALY. We can be 95% confident that the intervention would be considered 'good value' at $90 000/abstinent year at 25 weeks and $500/abstinent year at 78 weeks. While extended-release naltrexone appears to be effective in increasing both quality-adjusted life-years (QALYs) and abstinence, it does not appear to be cost-effective using generally accepted value

    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.

    As the United States grapples with an opioid epidemic, expanding access to effective treatment for opioid use disorder is a major public health priority. Identifying effective policy tools that can be used to expand access to care is critically important. This article examines the relationship between state-targeted funding and technical assistance and adoption of three medications for treating opioid use disorder: oral naltrexone, injectable naltrexone, and buprenorphine. This study draws from the 2013-2014 wave of the National Drug Abuse Treatment System Survey, a nationally representative, longitudinal study of substance use disorder treatment programs. The sample includes data from 695 treatment programs (85.5% response rate) and representatives from single-state agencies in 49 states and Washington, D.C. (98% response rate). Logistic regression was used to examine the relationships of single-state agency targeted funding and technical assistance to availability of opioid use disorder medications among treatment programs. State-targeted funding was associated with increased program-level adoption of oral naltrexone (adjusted odds ratio [AOR]=3.14, 95% confidence interval [CI]=1.49-6.60, p=.004) and buprenorphine (AOR=2.47, 95% CI=1.31-4.67, p=.006). Buprenorphine adoption was also correlated with state technical assistance to support medication provision (AOR=1.18, 95% CI=1.00-1.39, p=.049). State-targeted funding for medications may be a viable policy lever for increasing access to opioid use disorder medications. Given the historically low rates of opioid use disorder medication adoption in treatment programs, single-state agency targeted funding is a potentially important tool to reduce mortality and morbidity associated with opioid disorders and misuse.

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

    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.

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

    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.

    Purpose: The aim of the study was to test the hypothesis that aerobic Gram-negative bacteria (AGNB) play a crucial role in the pathogenesis of radiation-induced mucositis; consequently, selective elimination of these bacteria from the oral flora should result in a reduction of the mucositis. Methods and Materials: Head-and-neck cancer patients, when scheduled for treatment by external beam radiation therapy (EBRT), were randomized for prophylactic treatment with an oral paste containing either a placebo or a combination of the antibiotics polymyxin E, tobramycin, and amphotericin B (PTA group). Weekly, the objective and subjective mucositis scores and microbiologic counts of the oral flora were noted. The primary study endpoint was the mucositis grade after 3 weeks of EBRT. Results: Seventy-seven patients were evaluable. No statistically significant difference for the objective and subjective mucositis scores was observed between the two study arms (p=0.33). The percentage of patients with positive cultures of AGNB was significantly reduced in the PTA group (p=0.01). However, complete eradication of AGNB was not achieved. Conclusions: Selective elimination of AGNB of the oral flora did not result in a reduction of radiation-induced mucositis and therefore does not support the hypothesis that these bacteria play a crucial role in the pathogenesis of mucositis

    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.

    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

    DNA-spermidine (DA-51), which has been originally developed by Dr. Sekiguchi et al. as a protective agent against radiation-induced leukopenia, was submitted to clinical trial by the double blind test. The protective effect against radiation-induced leukopenia and side effect of DA-51 were compared with those of Inosine, selected as a control agent, on breast cancer cases receiving prophylactic irradiation. Daily dose of 2700 mg of DA-51 and 1800 mg of Inosine were administered orally during a 5 week period of irradiation. The differences between the white blood cell counts, the thrombocyte counts and the percentages of lymphocytes in the DA-51 and the Inosine treated groups were assessed at 1, 3 and 5 weeks by x/sup 2/ and T tests, and the following results are obtained: No significant difference in white blood cell or thrombocyte counts was demonstrated at 1, 3 or 5 weeks between the two groups. The only significant difference noted was in the percentage of lymphocyte at 5 weeks, and the thrombocyte counts at 3 weeks. DNA-spermidine is considered to be an effective drug against radiation-induced leukopenia, comparable to Inosine and without noticeable side effects.

    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)

    Aspirin and nonsteroidal anti-inflammatory agents are known to induce gastroduodenal complications such as ulcer, bleeding, and dyspepsia. In this study, we examined the prophylactic effect of rebamipide, an anti-ulcer agent with free-radical scavenging and anti-inflammatory effect, on acidified aspirin-induced gastric mucosal injury in rats. In addition, we investigated the mucosal barrier functions disrupted by aspirin. Oral administration of acidified aspirin resulted in linear hemorrhagic erosions with increasing myeloperoxidase activity and thiobarbituric acid-reactive substance concentrations in the gastric mucosa. Rebamipide suppressed these acidified aspirin-induced gastric lesions and inflammatory changes significantly, and its protective effect was more potent in the case of repeated (twice daily for 3 days) treatment than single treatment before aspirin administration. Immunostaining of zonula occludens (ZO)-1, one of the tight junctional proteins, was strengthened in rat gastric mucosa after repeated administration of rebamipide. In addition, aspirin induced the increasing transport of fluorescine isothiocyanate-labeled dextrans with localized disruption and decreased expression of ZO-1 protein on rat gastric mucosal cell line RGM-1. Rebamipide effectively prevented aspirin-induced permeability changes and disruption of ZO-1 distribution. These results suggest that rebamipide protects against aspirin-induced gastric mucosal lesions by preserving gastric epithelial cell-to cell integrity in addition to the anti-inflammatory effects.

    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

    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.

    Purpose: We report the experience of two French cancer centers in the treatment of oral cavity squamous cell carcinoma (SCC) in patients aged ≥80 years. Materials and methods: Two hundred and sixty patients aged ≥80 years with a primary oral cavity SCC were included in this retrospective analysis. Results: Sex ratio was near to 1. Tobacco or alcohol intoxication was the main risk factor for 66% of men and 16% of women and leukoplakia, lichen planus, or oral traumatism for 55% of women and 11% of men (p < 0.0001). Two hundred patients received a loco-regional (LR) treatment with a curative intent (surgery and/or radiotherapy), 29 with a palliative intent and 31 did not receive a LR treatment. Curative treatments were initially planned to be adapted to age in 118 patients (59%). The median disease-specific survival (DSS) was 29 months. In multivariate analysis, the independent prognostic factors for DSS were stage (HR = 0.42 [0.24-0.72]), age (HR = 0.43 [0.24-0.75]) and performance status (HR = 0.50 [0.27-0.95]). The median overall survival (OS) was 14 months. In multivariate analysis, the independent prognostic factors for OS were age (HR = 0.52 [0.35-0.79]), stage (HR = 0.56 [0.38-0.84]), tumor differentiation (HR = 0.60 [0.33-0.93]) and performance status (HR = 0.6 [0.37-0.97]). In patients treated with a curative intent, treatment adapted to age was not associated with a decreased overall survival or disease-specific survival as compared with the standard treatment. However, prophylactic lymph node treatment in stages I-II tumors decreased the rate of nodal recurrence from 38% to 6% (p = 0.01). Conclusion: This study emphasizes the need for prospective evaluation of standard and adapted schedules in elderly patients with oral cavity cancer.

    To compare the analgesic efficacy of oral tramadol and naproxen sodium on pain during insertion of an intrauterine device (IUD). Randomized, double-blinded, clinical trial (Canadian Task Force classification I). University-affiliated hospital. Single-center. One hundred three patients scheduled for insertion of an IUD. Patients were randomly assigned to receive oral tramadol 50 mg capsules (n = 35) or naproxen sodium 550 mg tablets (n = 34) or placebo (n = 34) 1 hour before insertion of the IUD. After insertion of the IUD, pain intensity was evaluated using a visual analog scale (VAS, 0-10). Adverse effects, patient satisfaction with the medication, and preference for using it during future insertions were also recorded. The VAS scores were significantly different during IUD insertion among the 3 groups (p = .001). Pain scores in the tramadol group were significantly lower than in the naproxen group (p = .003), and the scores in the naproxen group was significantly lower than in the control group (p = .001). Patient satisfaction with the medication and preference for its future use were significantly lower in the control group than in the other 2 groups (p = .001). Prophylactic analgesia using 50 mg tramadol and 550 mg naproxen, delivered orally, can be used to relieve pain during IUD insertion. However, tramadol capsules were found to be more effective than naproxen tablets. Copyright © 2012 AAGL. Published by Elsevier Inc. All rights reserved.

    Measles virus is a highly infectious morbillivirus responsible for major morbidity and mortality in unvaccinated humans. The related, zoonotic canine distemper virus (CDV) induces morbillivirus disease in ferrets with 100% lethality. We report an orally available, shelf-stable pan-morbillivirus inhibitor that targets the viral RNA polymerase. Prophylactic oral treatment of ferrets infected intranasally with a lethal CDV dose reduced viremia and prolonged survival. Ferrets infected with the same dose of virus that received post-infection treatment at the onset of viremia showed low-grade viral loads, remained asymptomatic, and recovered from infection, whereas control animals succumbed to the disease. Animals that recovered also mounted a robust immune response and were protected against rechallenge with a lethal CDV dose. Drug-resistant viral recombinants were generated and found to be attenuated and transmission-impaired compared to the genetic parent virus. These findings may pioneer a path toward an effective morbillivirus therapy that could aid measles eradication by synergizing with vaccination to close gaps in herd immunity due to vaccine refusal.

    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.

    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 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.

  18. Oral sex, oral health and orogenital infections

    Full Text Available Oral sex is commonly practiced by sexually active male-female and same-gender couples of various ages, including adolescents. The various type of oral sex practices are fellatio, cunnilingus and analingus. Oral sex is infrequently examined in research on adolescents; oral sex can transmit oral, respiratory, and genital pathogens. Oral health has a direct impact on the transmission of infection; a cut in your mouth, bleeding gums, lip sores or broken skin increases chances of infection. Although oral sex is considered a low risk activity, it is important to use protection and safer sex precautions. There are various methods of preventing infection during oral sex such as physical barriers, health and medical issues, ethical issues and oral hygiene and dental issues. The lesions or unhealthy periodontal status of oral cavity accelerates the phenomenon of transmission of infections into the circulation. Thus consequences of unhealthy or painful oral cavity are significant and oral health should be given paramount importance for the practice of oral sex.

    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.

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

    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...

    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

    Full Text Available Background. Antibiotic-associated diarrhea (AAD develops through the loss of normal bacterial intestinal flora. 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.

    Anti-drug antibodies in hemophilia patients substantially complicate treatment. Their elimination through immune tolerance induction (ITI) protocols poses enormous costs, and ITI is often ineffective for factor IX (FIX) inhibitors. Moreover, there is no prophylactic ITI protocol to prevent anti-drug antibody (ADA) formation. Using general immune suppression is problematic. To address this urgent unmet medical need, we delivered antigen bioencapsulated in plant cells to hemophilia B dogs. Commercial-scale production of CTB-FIX fusion expressed in lettuce chloroplasts was done in a hydroponic facility. CTB-FIX (∼1 mg/g) in lyophilized cells was stable with proper folding, disulfide bonds, and pentamer assembly after 30-month storage at ambient temperature. Robust suppression of immunoglobulin G (IgG)/inhibitor and IgE formation against intravenous FIX was observed in three of four hemophilia B dogs fed with lyophilized lettuce cells expressing CTB-FIX. No side effects were detected after feeding CTB-FIX-lyophilized plant cells for >300 days. Coagulation times were markedly shortened by intravenous FIX in orally tolerized treated dogs, in contrast to control dogs that formed high-titer antibodies to FIX. Commercial-scale production, stability, prolonged storage of lyophilized cells, and efficacy in tolerance induction in a large, non-rodent model of human disease offer a novel concept for oral tolerance and low-cost production and delivery of biopharmaceuticals.

    2007-01-01

    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.

    Extended-release naltrexone (XRNTX) is an effective treatment for alcohol use disorder (AUD). We sought to evaluate the feasibility, acceptability, and preliminary effectiveness and cost-effectiveness of XRNTX delivered as a stand-alone service to persons with severe AUD who are high utilizers of multiple urgent and emergency medical services (HUMS). Of 15 HUMS persons with severe AUD selected based on chart review, 11 agreed to participate. Participants received a mean of 4.5 injections (range 2-7). Modest benefits from XRNTX were observed in terms of patients' Urge-to-Drink Score and the costs of emergency medical services utilized. Though limited by a small sample size, costs including client utilization and study related expenses during the post-enrollment period were less than client utilization costs in the pre-enrollment period. We also observed non-significant improvements in the number of drinking days, but no change in quality of life as measured by the EQ-5D. Eighty-eight percent of participants perceived XRNTX as helping with their drinking. Findings need to be replicated in a larger study, however if replicated, the cost savings could be substantial.

    Chemotherapy and radiotherapy, whilst highly effective in the treatment of neoplasia, can also cause damage to healthy tissue. In particular, the alimentary tract may be badly affected. Severe inflammation, lesioning and ulceration can occur. Patients may experience intense pain, nausea and gastro-enteritis. They are also highly susceptible to infection. The disorder (mucositis) is a dose-limiting toxicity of therapy and affects around 500 000 patients world-wide annually. Oral and intestinal mucositis is multi-factorial in nature. The disruption or loss of rapidly dividing epithelial progenitor cells is a trigger for the onset of the disorder. However, the actual dysfunction that manifests and its severity and duration are greatly influenced by changes in other cell populations, immune responses and the effects of oral/gut flora. This complexity has hampered the development of effective palliative or preventative measures. Recent studies have concentrated on the use of bioactive/growth factors, hormones or interleukins to modify epithelial metabolism and reduce the susceptibility of the tract to mucositis. Some of these treatments appear to have considerable potential and are at present under clinical evaluation. This overview deals with the cellular changes and host responses that may lead to the development of mucositis of the oral cavity and gastrointestinal tract, and the potential of existing and novel palliative measures to limit or prevent the disorder. Presently available treatments do not prevent mucositis, but can limit its severity if used in combination. Poor oral health and existing epithelial damage predispose patients to mucositis. The elimination of dental problems or the minimization of existing damage to the alimentary tract, prior to the commencement of therapy, lowers their susceptibility. Measures that reduce the flora of the tract, before therapy, can also be helpful. Increased production of free radicals and the induction of inflammation are

    Full Text Available Background: The present study was aimed to evaluate the efficacy of acetaminophen plus dexamethasone on post-operative emergence agitation in pediatric adenotonsillectomy. Methods: A total of 128 patients were randomized and assigned among four groups as: Intravenous (IV dexamethasone, oral acetaminophen, IV dexamethasone plus oral acetaminophen, placebo. Group 1 received 0.2 mg/kg dexamethasone plus 0.25 mg/kg strawberry syrup 2 h before surgery. Group 2 received 20 mg/kg oral acetaminophen (0.25 ml/kg with 0.05 ml/kg IV normal saline. Group 3 received 20 mg/kg acetaminophen and 0.2 mg/kg dexamethasone intravenously. Group 4 received 0.25 ml/kg strawberry syrup and 0.05 ml/kg normal saline. Agitation was measured according to Richmond agitation sedation score in the post anesthetic care unit (PACU after admission, 10, 20 and 30 min after extubation. Pain score was measured with FACE scale. Nurse satisfaction was measured with verbal analog scale. If agitation scale was 3 ≥ or pain scale was 4 ≥ meperidine was prescribed. If symptoms did not control wit in 15 min midazolam was prescribed. Patients were discharged from PACU according Modified Alderet Score. Data were analyzed with ANOVA, Chi-square, and Kruskal-Wallis among four groups. P < 0.05 was considered statistically significant. Results: A total of 140 patients were recruited in the study, which 12 of them were excluded. Thus, 128 patients were randomized and assigned among four groups. The four treatment groups were generally matched at baseline data. Median of pain score in 0, 10, 20 and 30 min after extubation were different between each study group with the control group (<0.001, 0.003 respectively. Also median of agitation score in 0, 10, 20 and 30 min after extubation were different between each study group with the control group (<0.001. Incidence of pain and incidence of agitation after extubation were not statistically identical among groups (P < 0.001 and P = 0

    Cytomegalovirus (CMV) is acquired by the oral route in children, and primary infection is associated with abundant mucosal replication, as well as the establishment of latency in myeloid cells that results in lifelong infection. The efficiency of primary CMV infection in humans following oral exposure, however, is unknown. We consistently detected self-limited, low-level oral CMV shedding events, which we termed transient CMV infections, in a prospective birth cohort of 30 highly exposed CMV-uninfected infants. We estimated the likelihood of transient oral CMV infections by comparing their observed frequency to that of established primary infections, characterized by persistent high-level shedding, viremia, and seroconversion. We developed mathematical models of viral dynamics upon initial oral CMV infection and validated them using clinical shedding data. Transient infections comprised 76 to 88% of oral CMV shedding events. For this high percentage of transient infections to occur, we identified two mathematical prerequisites: a very small number of initially infected oral cells (1 to 4) and low viral infectivity (<1.5 new cells infected/cell). These observations indicate that oral CMV infection in infants typically begins with a single virus that spreads inefficiently to neighboring cells. Thus, although the incidence of CMV infection is high during infancy, our data provide a mechanistic framework to explain why multiple CMV exposures are typically required before infection is successfully established. These findings imply that a sufficiently primed immune response could prevent CMV from establishing latent infection in humans and support the achievability of a prophylactic CMV vaccine. IMPORTANCE CMV infects the majority of the world's population and is a major cause of birth defects. Developing a vaccine to prevent CMV infection would be extremely valuable but would be facilitated by a better understanding of how natural human CMV infection is acquired. We

    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.

  8. 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).

    To evaluate the comparative immunogenic potential of food grade Lactococcus lactis expressing outer membrane protein A (OmpA) of Shigella dysenteriae type-1 (SD-1) when administered either orally or intranasally. OmpA of SD-1 was cloned and expressed first in Escherichia coli and then in L. lactis. Presence of recombinant gene was confirmed by restriction enzyme digestion and immunoblot analysis. Using immobilized metal affinity chromatography, OmpA was purified from recombinant E. coliBL21 (DE3) and subcutaneously administered in BALB/c mice. Detection of OmpA-specific IgG antibodies by enzyme-linked immunosorbent assay (ELISA) confirmed the immunogenicity of OmpA. In order to establish r-L. lactis as a mucosal delivery vehicle, it was administered orally and nasally in BALB/c mice. Serum IgG and faecal IgA were assessed through ELISA to compare the relative potential of immunization routes and immunogenic potential of r-L. lactis. Immunization via the oral route proved superior to intranasal exposure. Recombinant L. lactis expressing OmpA of SD-1 was found to be immunogenic. Oral administration of r-L. lactis elicited higher systemic and mucosal immune response when compared with the nasal route. Using food grade recombinant L. lactis has implications in the development of a prophylactic against multidrug-resistant Shigella, which can be used as a prospective vaccine candidate. Evaluating mucosal routes of immunization demonstrated that the oral route of administration elicited better immune response against OmpA of Shigella. © 2016 The Society for Applied Microbiology.

    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.

    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.

    Mucuna pruriens is widely used in traditional medicine for treatments of various diseases. In certain region of Nigeria, the seed is used as oral prophylactics for snakebite. Rats pretreated with the aqueous extract from M. pruriens seed (MPE) were protected against the lethal effects of Naja sputatrix (Javan spitting cobra) venom [Tan et al., J Ethnopharmacol, 123 (2009) 356]. The pretreatment also protected against venom-induced histopathological changes in rat heart. To contribute to the understanding of the mechanism of cardio-protective action, the present study examined the effects of MPE-pretreatment on gene expression profile of rat heart as well as effect of MPE-pretreatment on N. sputatrix venom-induced gene expression alterations in rat heart. The gene expression profiles were examined by microarray analysis and verified by real time PCR. The results showed that pretreatment with MPE caused 50 genes in the rat heart substantially up-regulated of which 19 were related to immune responses, 7 were related to energy production and metabolism. The up-regulation of genes related to energy metabolism probably plays a role in maintaining the viability of the heart. Four other genes that were up-regulated (alpha synuclein, natriuretic peptide precursor, calsequestrin and triadin) were involved in the maintenance of homeostasis of the heart or maintaining its viability, thereby contributing to the direct protective action. The results demonstrated that protective effect of MPE pretreatment against snake venom poisoning may involve a direct action on the heart.

    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.

  17. Osteoradionecrosis prevention myths

    Wahl, Michael J.

    2006-01-01

    Purpose: To critically analyze controversial osteoradionecrosis (ORN) prevention techniques, including preradiation extractions of healthy or restorable teeth and the use of prophylactic antibiotics or hyperbaric oxygen (HBO) treatments for preradiation and postradiation extractions. Methods: The author reviewed ORN studies found on PubMed and in other article references, including studies on overall ORN incidence and pre- and postradiation incidence, with and without prophylactic HBO or antibiotics. Results: Owing in part to more efficient radiation techniques, the incidence of ORN has been declining in radiation patients over the last 2 decades, but the prevention of ORN remains controversial. A review of the available literature does not support the preradiation extraction of restorable or healthy teeth. There is also insufficient evidence to support the use of prophylactic HBO treatments or prophylactic antibiotics before extractions or other oral surgical procedures in radiation patients. Conclusions: To prevent ORN, irradiated dental patients should maintain a high level of oral health. A preradiation referral for a dental evaluation and close collaboration by a multidisciplinary team can be invaluable for radiation patients. As with most other dental patients, restorable and healthy teeth should be retained in irradiated patients. The use of prophylactic HBO or antibiotics should be reconsidered for preradiation and postradiation extractions

    Opioid addiction is a serious public health concern with severe health and social implications; therefore, extensive therapeutic efforts are required to keep users drug free. The two main pharmacological interventions, in the treatment of addiction, involve management with methadone an mu (μ)-opioid agonist and treatment with naltrexone, μ-opioid, kappa (κ)-opioid and delta (δ)-opioid antagonist. MET and NAL are believed to help individuals to derive maximum benefit from treatment and undergo a full recovery. The aim of this study was to determine the localization and distribution of MET and NAL, over a 24-hour period in rodent brain, in order to investigate the differences in their respective regional brain distributions. This would provide a better understanding of the role of each individual drug in the treatment of addiction, especially NAL, whose efficacy is controversial. Tissue distribution was determined by using mass spectrometric imaging (MSI), in combination with quantification via liquid chromatography tandem mass spectrometry. MSI image analysis showed that MET was highly localized in the striatal and hippocampal regions, including the nucleus caudate, putamen and the upper cortex. NAL was distributed with high intensities in the mesocorticolimbic system including areas of the cortex, caudate putamen and ventral pallidum regions. Our results demonstrate that MET and NAL are highly localized in the brain regions with a high density of μ-receptors, the primary sites of heroin binding. These areas are strongly implicated in the development of addiction and are the major pathways that mediate brain stimulation during reward. © 2018 Society for the Study of Addiction.

    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.

    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

    Medical literature provides only scarce data about the degree of pain experienced by patients undergoing a bone marrow aspiration and biopsy (BMAB), and little is known about the factors that can modify the perception of pain. In this study, we evaluated the effectiveness of a combination of analgesia and anxiolysis in reducing the pain score of patients undergoing BMAB. Eighty-four consecutive adult patients underwent BMAB after local anesthesia with 5 mL of lidocaine hydrochloride 1% aqueous solution in the left posterior superior iliac crest. Analgesia was obtained with acetaminophen 650 mg and oxycodone 10 mg, and anxiolysis was obtained with lorazepam 2 mg, all drugs given once orally 30 min before the procedure. We assessed the pain level with the Wong-Baker Faces Pain Rating Scale, which distinguishes six levels of pain, from 0 to 5. The 34 patients who received an oral administration of analgesia and anxiolysis reported pain at lower levels, i.e., in the range of 0-2, more frequently than the 50 patients who underwent BMAB without analgesia/anxiolysis (78% vs 64%, respectively). Among several predictors analyzed using a multivariate regression model, three were found to be associated with decreased pain level: the use of analgesia/anxiolysis, male sex, and increase in age (all with p values <0.05). Length of the extracted bone specimen, body mass index, and need of a spinal needle for anesthesia in obese patients did not predict for pain level. An oral administration of prophylactic regimen of analgesia and anxiolysis, at the above-mentioned doses, produced a statistically significant reduction of the perception of pain in patients undergoing BMAB, but its effect did not seem to provide a major and clinically significant reduction of pain level.

    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.

    Full Text Available INTRODUCTION: Oral Myiasis, a condition of infestation of the body by fly larvae (maggots is a rare pathology in humans. It is associated with poor oral hygiene, alcoholism, senility, suppurating lesions, severe halitosis. It is seen frequently in tropical countries and hot climatic regions. The reported cases in literature of oral Myiasis associated with oral cancer are few. The treatment is a mechanical removal of the maggots but a systemic treatment with Ivermectin, a semi - synthetic macrolide antibiotic, has been used successfully for treatment for oral m yiasis. We present a case of 55 yr old male alcoholic patient with oral myiasis with extensive proliferative growth of oral cavity. Our patient was managed with manual debridement and administration of systemic ivermect in along with antibiotic coverage. Incisional biopsy of the proliferative lesion showed well differentiated squamous cell carcinoma. Thus our patient showed presence of oral myiasis in association with oral squamous cell carcinoma.

    Oral human papillomavirus (HPV) infection is the cause of 40% to 80% of oropharyngeal cancers; yet, no published study has examined the role of oral health in oral HPV infection, either independently or in conjunction with other risk factors. This study examined the relation between oral health and oral HPV infection and the interactive effects of oral health, smoking, and oral sex on oral HPV infection. Our analyses comprised 3,439 participants ages 30 to 69 years for whom data on oral HPV and oral health were available from the nationally representative 2009-2010 National Health and Nutrition Examination Survey. Results showed that higher unadjusted prevalence of oral HPV infection was associated with four measures of oral health, including self-rated oral health as poor-to-fair [prevalence ratio (PR) = 1.56; 95% confidence interval (CI), 1.25-1.95], indicated the possibility of gum disease (PR = 1.51; 95% CI, 1.13-2.01), reported use of mouthwash to treat dental problems in the past week (PR = 1.28; 95% CI, 1.07-1.52), and higher number of teeth lost (Ptrend = 0.035). In multivariable logistic regression models, oral HPV infection had a statistically significant association with self-rated overall oral health (OR = 1.55; 95% CI, 1.15-2.09), independent of smoking and oral sex. In conclusion, poor oral health was an independent risk factor of oral HPV infection, irrespective of smoking and oral sex practices. Public health interventions may aim to promote oral hygiene and oral health as an additional measure to prevent HPV-related oral cancers.

    Patients with schizophrenia experience higher rates of obesity as well as related morbidity and mortality than the general population does. Women with schizophrenia are at particular risk for antipsychotic-associated weight gain, obesity, and related medical disorders such as diabetes and cardiovascular disease. Given preclinical studies revealing the role of the endogenous opioid systems in human appetite and the potential of antipsychotic medications to interfere with this system, we hypothesized that opioid antagonists may be beneficial in arresting antipsychotic-associated weight gain and promoting further weight loss in women with schizophrenia. In the present study, 24 overweight women with a diagnosis of schizophrenia or schizoaffective disorder were randomized to placebo or naltrexone (NTX) 25 mg/d for 8 weeks. The primary outcome measure was a change in body weight from baseline. The patients in the NTX group had significant weight loss (-3.40 kg) compared with weight gain (+1.37 kg) in the patients in the placebo group. Mainly, nondiabetic subjects lost weight in the NTX arm. These data support the need to further investigate the role of D2 blockade in reducing food reward-based overeating. A larger study addressing the weaknesses of this pilot study is currently underway.

    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)

But, the meta-analyses do not recommend nor discard the use of prophylactic pre-operative antibiotics. The scarcity of controlled clinical trials in paediatric population further vitiates the matter. This study assessed the difference in the rate of early post-operative wound infection cases in children who received single dose of pre-operative antibiotics and children who did not receive antibiotics after inguinal herniotomy and orchiopexy. Materials and Methods: This randomised prospective study was conducted in Paediatric Surgery department of PGIMER Chandigarh. Out of 251 patients, 112 patients were randomised to the case group and 139 were ascribed to the control group. The patients in control group were given a standard regimen of single dose of intravenous antibiotic at the time of induction followed by 3-4 days of oral antibiotic. Case group patients underwent the surgical procedure in similar manner with no antibiotic either at the time of induction or post-operatively. Results: The incidence of surgical site infection in case group was 3.73 % and that in control group was 2.22%. The observed difference in the incidence of surgical site infection was statistically insignificant (P value = 0.7027. The overall infection rate in case and control group was 2.89%. Conclusions: Our preliminary experience suggests that there is no statistically significant difference in the proportion of early post-operative wound infection between the patients who received single dose of pre-operative antibiotics and the patients who received no antibiotics after inguinal herniotomy and orchiopexy. The risk of surgical site infection in paediatric heriotomies does not increase even if the child′s weight is less than his/her expected weight for age.

    Purpose: To evaluate the efficiency of Helium-Neon (He-Ne) laser in the prevention of oral mucositis induced by high dose chemoradiotherapy before autologous bone marrow transplantation (BMT). Methods and Materials: Between 1993 and 1995, 30 consecutive patients receiving an autologous peripheral stem-cell or bone marrow transplant (BMT) after high dose chemoradiotherapy were randomized to possibly receive prophylactic laser to the oral mucosa after giving informed consent. Chemotherapy consisted of cyclophosphamide, 60 mg/kg intravenously (IV) on day (d)-5 and d-4 in 27 cases, or melphalan 140 mg/kg IV on d-4 in three cases. Total body irradiation (TBI) consisted of 12 Gy midplane dose in six fractions (4 Gy/day for three days). He-Ne laser (632.8 nm wavelength, power 60 mW) applications were performed daily from d-5 to d-1 on five anatomic sites of the oral mucosa. Oral examination was performed daily from d0 to d + 20. Mucositis was scored according to an oral exam guide with a 16 item scale of which four were assessed by the patients themselves. Mean daily self assessment scores for oral pain, ability to swallow and oral dryness were measured. A daily mucositis index (DMI) and a cumulative oral mucositis score (COMS) were established. Requirement for narcotics and parenteral nutrition was recorded. Results: The COMS was significantly reduced among laser treated (L+) patients (p = 0.04). The improvement of DMI in L+ patients was also statistically significant (p < 0.05) from d + 2 to d + 7. Occurrence and duration of grade III oral mucositis were reduced in L+ patients (p = 0.01). Laser applications reduced oral pain as assessed by patients (p = 0.05) and L+ patients required less morphine (p = 0.05). Xerostomia and ability to swallow were improved among the L+ patients (p = 0.005 and p = 0.01, respectively). Requirement for parenteral nutrition was not reduced (p = NS). Conclusion: Helium-Neon laser treatment was well tolerated, feasible in all cases, and

    Full Text Available BACKGROUND Febrile seizures occurring in a child older than one month during an episode of fever affect 2% to 4% of children in Great Britain and the United States and recur in 30%. Rapid-acting antiepileptics and antipyretics given during subsequent fever episodes have been used to avoid the adverse effects of continuous antiepileptic drugs. OBJECTIVE To evaluate the effectiveness and safety of antiepileptic and antipyretic drugs used prophylactically to treat children with febrile seizures. METHODS Search methods: We searched the Cochrane Central Register of Controlled Trials (CENTRAL (The Cochrane Library 2011. Issue 3; MEDLINE (1966 to May 2011; EMBASE (1966 to May 2011; Database of Abstracts of Reviews of Effectiveness (DARE (May 2011. No language restrictions were imposed. We also contacted researchers in the field to identify continuing or unpublished studies. Selection criteria: Trials using randomized or quasi-randomized patient allocation that compared the use of antiepileptic or antipyretic agents with each other, placebo or no treatment. Data collection and analysis: Two review authors (RN and MO independently applied pre-defined criteria to select trials for inclusion and extracted the pre-defined relevant data, recording methods for randomization, blinding and exclusions. Outcomes assessed were seizure recurrence at 6, 12, 18, 24, 36 months and at age 5 to 6 years in the intervention and non-intervention groups, and adverse medication effects. The presence of publication bias was assessed using funnel plots. MAIN RESULTS Thirty-six articles describing 26 randomized trials with 2740 randomized participants were included. Thirteen interventions of continuous or intermittent prophylaxis and their control treatments were analyzed. Methodological quality was moderate to poor in most studies. We could not do a meta-analysis for 8 of the 13 comparisons due to insufficient numbers of trials. No significant benefit for valproate, pyridoxine

    Oral diseases are known to be closely associated with oral biofilm metabolism, while cancer tissue is reported to possess specific metabolism such as the 'Warburg effect'. Metabolomics might be a useful method for clarifying the whole metabolic systems that operate in oral biofilm and oral cancer, however, technical limitations have hampered such research. Fortunately, metabolomics techniques have developed rapidly in the past decade, which has helped to solve these difficulties. In vivo metabolomic analyses of the oral biofilm have produced various findings. Some of these findings agreed with the in vitro results obtained in conventional metabolic studies using representative oral bacteria, while others differed markedly from them. Metabolomic analyses of oral cancer tissue not only revealed differences between metabolomic profiles of cancer and normal tissue, but have also suggested a specific metabolic system operates in oral cancer tissue. Saliva contains a variety of metabolites, some of which might be associated with oral or systemic disease; therefore, metabolomics analysis of saliva could be useful for identifying disease-specific biomarkers. Metabolomic analyses of the oral biofilm, oral cancer, and saliva could contribute to the development of accurate diagnostic, techniques, safe and effective treatments, and preventive strategies for oral and systemic diseases.

    Oral cancer is one of the major global threats to public health. The development of oral cancer is a tobacco-related multistep and multifocal process involving field cancerization and carcinogenesis. The rationale for molecular-targeted prevention of oral cancer is promising. Biomarkers of genomic instability, including aneuploidy and allelic imbalance, are possible to measure the cancer risk of oral premalignancies. Understanding of the biology of oral carcinogenesis will yield important adv...

  6. Contralateral prophylactic mastectomy: current perspectives

    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.

    A growing body of evidence implicates human oral bacteria in the etiology of oral and gastrointestinal cancers. Epidemiological studies consistently report increased risks of these cancers in men and women with periodontal disease or tooth loss, conditions caused by oral bacteria. More than 700 bacterial species inhabit the oral cavity, including at least 11 bacterial phyla and 70 genera. Oral bacteria may activate alcohol and smoking-related carcinogens locally or act systemically, through c...

Methods: This open-label, single-arm study was conducted in 157 primary care centers in the United States. A total of 684 opioid-experienced adults with chronic moderate-to-severe pain were converted to oral administration of MSN from transdermal fentanyl and oral formulations of hydrocodone, hydromorphone, methadone, oxycodone, oxymorphone, and other morphine products using a standardized conversion guide. The primary endpoint was the percentage of patients achieving a stable MSN dose within a 6-week titration phase. Secondary endpoints included duration of time to stable dose, number of titration steps, safety and efficacy measures, and investigator assessment of conversion guide utility. Results: Of the 684 patients, 51.3% were converted to a stable dose of MSN (95% confidence interval: 47.5%, 55.1%. The mean (standard deviation number of days to stable dose was 20 (8.94, and number of titration steps to stable dose was 2.4 (1.37. The majority of adverse events were mild/moderate and consistent with opioid therapy. Mean pain scores at stable dose decreased from baseline. Investigators were generally satisfied with the conversion guide and, in 94% of cases, reported they would use it again. Conclusion: Conversion to MSN treatment using the standardized MSN conversion guide was an attainable goal in approximately half of the population of

    We recently reported that in rats prenatally x-irradiated on gestation day 14 with 1 Gy, postnatal chronic application of the opioid antagonist naltrexone (Nx) led to a remarkable growth spurt of the microencephalic brain. In the present study we present histological and autoradiographic results found in the subependymal layer (SEL) of the forebrain lateral ventricles. Nx led to an intermittent augmentation of the mitotic index of the x-irradiated brains within a postnatal observation period of 24 weeks. The most conspicuous finding was transient hyperplasia of the SEL at 4-6 weeks of age which occurred in close proximity to an intact ependymal lining. Districts of the lateral ventricles which were denuded from ependyme and where the rest of the ependymal layer (EL) was dislocated peripherally showed upon Nx treatment a long-lasting SEL hyperplasia with a tendency towards dysplasia. These results revealed that repair proliferation of embryotoxic x-irradiation is normally under strong control by the opioid system. If that system, which exerts a suppressing effect upon glial growth, is blocked by Nx, prominent hyperplastic reactions occur which may be useful for repairing the lesion pattern

    Full Text Available Myiasis is a pathologic condition in humans occurring because of parasitic infestation. Parasites causing myiasis belong to the order Diptera. Oral myiasis is seen secondary to oral wounds, suppurative lesions, and extraction wounds, especially in individuals with neurological deficit. In such cases, neglected oral hygiene and halitosis attracts the flies to lay eggs in oral wounds resulting in oral myiasis. We present a case of oral myiasis in 40-year-old male patient with mental disability and history of epilepsy.

    We have previously shown that prophylactic oral administration of transgenic rice seeds expressing hypoallergenic modified antigens suppressed the development of allergic conjunctivitis induced by Japanese cedar pollen. We have now investigated the efficacy of oral immunotherapy with such transgenic rice for established allergic conjunctivitis in mice. BALB/c mice were sensitized with two intraperitoneal injections of Japanese cedar pollen in alum, challenged with pollen in eyedrops, and then fed for 16 days with transgenic rice seeds expressing modified Japanese cedar pollen allergens Cry j 1 and Cry j 2 or with nontransgenic rice seeds as a control. They were then challenged twice with pollen in eyedrops, with clinical signs being evaluated at 15 min after the first challenge and the eyes, blood, spleen, and lymph nodes being isolated at 24 h after the second challenge. The number of eosinophils in the conjunctiva and the clinical score for conjunctivitis were both significantly lower in mice fed the transgenic rice than in those fed nontransgenic rice. Oral vaccination with transgenic rice seeds also resulted in a significant increase in the production of IFN-γ by splenocytes, whereas it had no effect on the number of CD4 + CD25
