    Full Text Available Abstract Background Studies of toxicity and unintended side effects can lead to improved drug safety and efficacy. One promising form of study comes from molecular systems biology in the form of "systems pharmacology". Systems pharmacology combines data from clinical observation and molecular biology. This approach is new, however, and there are few examples of how it can practically predict adverse reactions (ADRs from an experimental drug with acceptable accuracy. Results We have developed a new and practical computational framework to accurately predict ADRs of trial drugs. We combine clinical observation data with drug target data, protein-protein interaction (PPI networks, and gene ontology (GO annotations. We use cardiotoxicity, one of the major causes for drug withdrawals, as a case study to demonstrate the power of the framework. Our results show that an in silico model built on this framework can achieve a satisfactory cardiotoxicity ADR prediction performance (median AUC = 0.771, Accuracy = 0.675, Sensitivity = 0.632, and Specificity = 0.789. Our results also demonstrate the significance of incorporating prior knowledge, including gene networks and gene annotations, to improve future ADR assessments. Conclusions Biomolecular network and gene annotation information can significantly improve the predictive accuracy of ADR of drugs under development. The use of PPI networks can increase prediction specificity and the use of GO annotations can increase prediction sensitivity. Using cardiotoxicity as an example, we are able to further identify cardiotoxicity-related proteins among drug target expanding PPI networks. The systems pharmacology approach that we developed in this study can be generally applicable to all future developmental drug ADR assessments and predictions.

    Pain is a widespread symptom in clinical practice. Older adults and chronically ill patients are particularly affected. In multimorbid geriatric patients, pharmacological pain treatment is an extension of a previously existing multimedication. Besides the efficacy of pain treatment, drug side effects and drug-drug interactions have to be taken into account to minimize the health risk for these patients. Apart from the number of prescriptions, the age-related pharmacokinetic and pharmacodynamic changes significantly increase the risk among older adults. The use of non-steroidal anti-inflammatory drugs (NSAID) is widespread but NSAIDs have the highest risk of adverse drug reactions and drug interactions. In particular, the gastrointestinal, cardiovascular, renal and coagulation systems are affected. Apart from the known toxic effect on the liver (in high doses), paracetamol (acetaminophen) has similar risks although to a lesser degree. According to current data, metamizol is actually better than its reputation suggests. The risk of potential drug interactions seems to be low. Apart from the risk of sedation in combination with other drugs, tramadol and other opioids can induce the serotonin syndrome. Among older adults, especially in the case of polypharmacy, an individualized approach should be considered instead of sticking to the pain management recommended by the World Health Organization (WHO) in order to minimize drug-drug interactions and adverse drug reactions.

    Since the introduction of antipsychotic medication for the treatment of psychosis, a wide range of different types of antipsychotic drugs have been developed while their side effects have become evident. The side effects of both the typical and atypical generation of antipsychotics have important consequences for the quality of life of recipients, stigma experienced and also the level of care of patients. It is well acknowledged that the side effects of antipsychotics reduce compliance with the medication. In this review the data for an association between typical and atypical antipsychotics and the main side effects that are well-supported in the literature was explored: weight gain and associated metabolic effects; extrapyramidal symptoms and tardive dyskinesia; prolactin elevation and associated sexual effects; QTc elongation; and a group of miscellaneous side effects. It has been demonstrated that the production of adverse effects following the use of antipsychotic medication differs widely both between atypical and typical drugs but also within these subgroups. Considering the wide range of antipsychotics available amongst both groups and the differing effects they have on patients in terms of side effects, there is reason to believe that a more personalised approach to antipsychotic treatment should be considered. Additionally, screening for risk factors, screening for the appearance of side effects, as well as good communication with patients about the side effects and other options available are important tasks for clinicians in order to optimise concordance with medication.

    We analyzed the cases of side effects due to antipsychotics reported to Japan's Pharmaceuticals and Medical Devices Agency (PMDA) from Jan. 2004 to Dec. 2012. We used the Japanese Adverse Drug Event Report Database (JADER) and analyzed 136 of 216,945 cases using the defined terms. We also checked the cardiac adverse effects listed in the package inserts of the antipsychotics involved. We found cases of Ikr blockade resulting in sudden death (49 cases), electrocardiogram QT prolonged (29 cases), torsade de pointes (TdP, 19 cases), ventricular fibrillation (VF, 10 cases). M2 receptor blockade was observed in tachycardia (8 cases) and sinus tachycardia (3 cases). Calmodulin blockade was involved in reported cardiomyopathy (3 cases) and myocarditis (1 case). Multiple adverse events were reported simultaneously in 14 cases. Our search of package inserts revealed warnings regarding electrocardiogram QT prolongation (24 drugs), tachycardia (23), sudden death (18), TdP (14), VF (3), myocarditis (1) and cardiomyopathy (1). We suggest that when an antipsychotic is prescribed, the patient should be monitored regularly with ECG, blood tests, and/or biochemical tests to avoid adverse cardiac effects. PMID:25069255

    Pharmacotherapy directed toward reducing body weight may provide benefits for both curbing obesity and lowering the risk of obesity-associated comorbidities; however, many weight loss medications have been withdrawn from the market because of serious adverse effects. Examples include pulmonary hypertension (aminorex), cardiovascular toxicity, e.g. flenfluramine-induced valvopathy, stroke [phenylpropanolamine (PPA)], excess non-fatal cardiovascular events (sibutramine), and neuro-psychiatric issues (rimonabant; approved in Europe, but not in the USA). This negative experience has helped mould the current drug development and approval process for new anti-obesity drugs. Differences between the US Food and Drug Administration (FDA) and the European Medicines Agency, however, in perceptions of risk-benefit considerations for individual drugs have resulted in discrepancies in approval and/or withdrawal of weight-reducing medications. Thus, two drugs recently approved by the FDA, i.e. lorcaserin and phentermine + topiramate extended release, are not available in Europe. In contrast, naltrexone sustained release (SR)/bupropion SR received FDA approval, and liraglutide 3.0 mg was recently approved in both the USA and Europe. Regulatory strategies adopted by the FDA to manage the potential for uncommon but potentially serious post-marketing toxicity include: (i) risk evaluation and mitigation strategy programmes; (ii) stipulating post-marketing safety trials; (iii) considering responder rates and limiting cumulative exposure by discontinuation if weight loss is not attained within a reasonable timeframe; and (iv) requiring large cardiovascular outcome trials before or after approval. We chronicle the adverse effects of anti-obesity pharmacotherapy and consider how the history of high-profile toxicity issues has shaped the current regulatory landscape for new and future weight-reducing drugs.

    Full Text Available Botulinum toxin A (BoNT-A injections for treatment of spasticity in patients with cerebral palsy (CP have been used for about two decades. The treatment is considered safe but a low frequency of adverse events (AE has been reported. A good method to report AEs is necessary to verify the safety of the treatment. We decided to use an active surveillance of treatment-induced harm using a questionnaire we created. We studied the incidence of reported AEs and side effects in patients with CP treated with BoNT-A. We investigated the relationship between the incidence of AEs or side effects and gender, age, weight, total dose, dose per body weight, Gross Motor Function Classification System (GMFCS and number of treated body parts. Seventy-four patients with CP participated in our study. In 54 (51% of 105 BoNT-A treatments performed in 45 (61% patients, there were 95 AEs and side effects reported, out of which 50 were generalized and/or focal distant. Severe AEs occurred in three patients (4%, and their BoNT-A treatment was discontinued. Consecutive collection of the AE and side-effect incidence using our questionnaire can increase the safety of BoNT-A treatment in patients with CP.

    Full Text Available BACKGROUND - Synthetic cannabinoids in smoking mixtures (such as Spice or as raw powder are sold for recreational use as an alternative to herbal cannabis (hashish and marijuana. Although clinical case studies have documented an array of side effects, there is also information available at Internet based drug discussion forums. AIM - Our study investigates experiences of side effects from use of synthetic cannabinoids, as described and anonymously shared on Swedish online discussion forums. METHODS - A systematic search yielded 254 unique and publicly available self-reports from the Swedish forum flashback.org. These texts were analysed thematically, which resulted in 32 sub-themes, which were combined into three overarching themes. RESULTS & CONCLUSION - The experiences of negative side effects were described as (1 Adverse reactions during acute intoxication; (2 Hangover the day after intoxication; (3 Dependency and withdrawal after long-term use. The first theme was characterized by an array of fierce and unpredictable side effects as tachycardia, anxiety, fear and nausea. The acute intoxication reactions were congruent with the side effects published in clinical case studies. The day after intoxication included residual effects of dullness, apathy, nausea and headache. Long-term use resulted in dependency and experiences of being emotionally numb and disconnected. Furthermore, withdrawal was described as sweating, shaking, loss of appetite and insomnia. Both the hangover and the long-term effects have previously been given little scientific attention and need to be investigated further. Drug related Internet discussion forums constitute an overlooked source of information which can aid in the identification of previously unknown risks and effects

    Background and purpose: Individual radiosensitivity is an inherent characteristic, associated with an increased reaction to ionizing radiation on the human body. Biological endpoints such as clonogenic survival, chromosome aberration formation and repair capacity of radiation-induced damage have been applied to evaluate individual radiosensitivity in vitro. 5%-7% of cancer patients develop adverse side effects to radiation therapy in normal tissues within the treatment field, which are referred as 'clinical radiation reactions' and include acute effects, late effects and cancer induction. It has been hypothesized that the occurrence and severity of these reactions are mainly influenced by genetic susceptibility to radiation. Additionally, the nature of the genetic disorders associated with hypersensitivity to radiotherapy suggests that DNA repair mechanisms are involved. Consequently, the characterization of DNA repair in lymphocytes through cytokinesis blocked micronucleus (MN) and alkaline single-cell micro...

    Full Text Available Pharmaceutical care (PC has been shown to improve the outcome of drug therapy in many disease conditions. HIV/AIDS is one of the disease conditions that are fraught with many problems that can benefit from this new emphasis of pharmacy practice also known as ‘pharmacists care’. Adverse drug reactions or effects are unintended and undesirable effects of drugs other than their known and expected actions which can be unpleasant and sometimes fatal. This study is designed to evaluate the impact of pharmaceutical care activities on the occurrence of side/adverse drug reactions in HIV/AIDS patients receiving antiretroviral drugs. The components of the American society of health-system pharmacists (ASHP guidelines on ‘standardized method for pharmaceutical care’ was used as a data collection instrument to evaluate, document and intervene in the antiretroviral therapy of about one thousand four hundred and seventy three (1,473 patients. The study identified about sixty (60 different types of side/adverse effects occurring among these patients through observation and patient complaints. The study also showed significant reduction in the incidence of side/adverse drug effects following the Pharmacist’s intervention activities, p ≥ 0.5. The study showed that pharmacists’ interventions in antiretroviral drug therapy through Pharmaceutical care can significantly reduce the incidence of side/adverse drug effects in HIV/AIDS patients receiving antiretroviral drugs.

    Background and purpose: Individual radiosensitivity is an inherent characteristic, associated with an increased reaction to ionizing radiation on the human body. Biological endpoints such as clonogenic survival, chromosome aberration formation and repair capacity of radiation-induced damage have been applied to evaluate individual radiosensitivity in vitro. 5%-7% of cancer patients develop adverse side effects to radiation therapy in normal tissues within the treatment field, which are referred as 'clinical radiation reactions' and include acute effects, late effects and cancer induction. It has been hypothesized that the occurrence and severity of these reactions are mainly influenced by genetic susceptibility to radiation. Additionally, the nature of the genetic disorders associated with hypersensitivity to radiotherapy suggests that DNA repair mechanisms are involved. Consequently, the characterization of DNA repair in lymphocytes through cytokinesis blocked micronucleus (MN) and alkaline single-cell micro gel electrophoresis (comet) assays could be suitable approaches to evaluate individual radiosensitivity in vitro. The MN assay is an established cytogenetic technique to evaluate intrinsic cell radiosensitivity in tumor cells and lymphocytes; comet assay is a sensitive and rapid method for measuring DNA damage and repair in individual cells. The aims of this study were: 1) To assess the in vitro radiosensitivity of peripheral blood lymphocytes from two groups of cancer patients (retrospectively and prospectively studied), using MN and comet assays, in comparison with the observed clinical response; and 2) To test the predictive potential of both techniques. Materials and methods: 38 cancer patients receiving radiation therapy were enrolled in this study. The tumor sites were: head and neck (n 25) and cervix (n = 13). Nineteen patients were evaluated about 6-18 month after radiotherapy (retrospective group) and 19 patients were evaluated prior, mid-way and on

    Phenytoin is an established drug in the treatment of acute repetitive seizures and status epilepticus. One of its main advantages over benzodiazepines is the less sedative effect. However, the possibility of cardiovascular adverse effects with the intravenous use of phenytoin cause a reluctance to its usage, and this has lead to a search for safer anticonvulsant drugs. In this study, we aimed to review the studies which evaluated the safety of phenytoin with respect to cardiovascular adverse effects. The original clinical trials and case reports listed in PUBMED in English language between the years of 1946-2014 were evaluated. As the key words, "phenytoin, diphenylhydantoin, epilepsy, seizure, cardiac toxicity, asystole, arrhythmia, respiratory arrest, hypotension, death" were used. Thirty-two clinical trials and ten case reports were identified. In the case reports, a rapid infusion rate (>50 mg/min) of phenytoin appeared as the major cause of increased mortality. In contrast, no serious cardiovascular adverse effects leading to death were met in the clinical trials which applied the recommended infusion rate and dosages. An infusion rate of 50 mg/min was reported to be safe for young patients. For old patients and patients with a cardiovascular co-morbidity, a slower infusion rate was recommended with a careful follow-up of heart rhythm and blood pressure. No cardiovascular adverse effect was reported in oral phenytoin overdoses except one case with a very high serum phenytoin level and hypoalbuminemia. Phenytoin is an effective and well tolerated drug in the treatment of epilepsy. Intravenous phenytoin is safe when given at recommended infusion rates and doses. PMID:26645393

    Electroconvulsive therapy (ECT) is an effective treatment commonly used for depression and other major psychiatric disorders. We discuss potential adverse effects (AEs) associated with ECT and strategies for their prevention and management. Common acute AEs include headache, nausea, myalgia, and confusion; these are self-limiting and are managed symptomatically. Serious but uncommon AEs include cardiovascular, pulmonary, and cerebrovascular events; these may be minimized with screening for risk factors and by physiologic monitoring. Although most cognitive AEs of ECT are short-lasting, troublesome retrograde amnesia may rarely persist. Modifications of and improvements in treatment techniques minimize cognitive and other AEs.

    High doses of synthetic antioxidative vitamins: A, E, C and β-carotene are often used on long-term basis in numerous preventive and therapeutic medical applications. Instead of expected health effects, the use of those vitamins may however lead to cases of hypervitaminosis and even to intoxication. The article points out main principles of safety which are to be observed during supplementation with antioxidative vitamins. Toxic effects resulting from erroneous administration of high doses of those substances on organs and systems of the organism are also discussed. Attention is drawn to interactions of antioxidative vitamins with concomitantly used drugs, as well as intensification of adverse effects caused by various exogenous chemical factors. Moreover, the article presents the evaluation of supplementation with these vitamins, which was performed in large studies. PMID:22528540

  7. Hematological Side Effects of Atypical Antipsychotic Drugs

    2009-10-01

    Full Text Available Atypical antipsychotics cause less frequently extrapyramidal system symptoms, neuroleptic malignant syndrome and hyperprolactinemia than typical antipsychotics. However hematological side effects such as leukopenia and neutropenia could occur during treatment with atypical antipsychotics. These side effects could lead to life threatening situations and the mortality rate due to drug related agranulocytosis is about 5-10%. There are several hypothesis describing the mechanisms underlying drug induced leukopenia and/or neutropenia such as direct toxic effects of these drugs upon the bone marrow or myeloid precursors, immunologic destruction of the granulocytes or supression of the granulopoiesis. Clozapine is the antipsychotic agent which has been most commonly associated with agranulocytosis. A nitrenium ion which is formed by the bioactivation of clozapine is thought to have an important role in the pathophysiogy of this adverse effect. Aside from clozapine, there are several case reports reporting an association between olanzapine, quetiapine, risperidone, ziprasidone, aripiprazole and leukopenia. We did not find any study or case report presenting amisulpride or sulpride related hematological side effects in our literature search. Patients who had hematological side effects during their previous antipsychotic drug treatments and who had lower baseline blood leukocyte counts, have higher risk to develop leukopenia or neutropenia during their current antipsychotic treatment. Once leukopenia and neutropenia develops, drugs thought to be responsible for this side effect should be discontinued or dosages should be lowered. In some cases iniatition of lithium or G-CSF (granulocyte colony-stimulating factor therapy may be helpful in normalizing blood cell counts. Clinicans should avoid any combination of drugs known to cause hematological side effects. Besides during antipsychotic treatment, infection symptoms such as fever, cough, sore throat or

    Life-threatening and benign drug reactions occur frequently in the skin, affecting 8 % of the general population and 2-3 % of all hospitalized patients, emphasizing the need for physicians to effectively recognize and manage patients with drug-induced eruptions. Neurologic medications represent a vast array of drug classes with cutaneous side effects. Approximately 7 % of the United States (US) adult population is affected by adult-onset neurological disorders, reflecting a large number of patients on neurologic drug therapies. This review elucidates the cutaneous reactions associated with medications approved by the US Food and Drug Administration (FDA) to treat the following neurologic pathologies: Alzheimer disease, amyotrophic lateral sclerosis, epilepsy, Huntington disease, migraine, multiple sclerosis, Parkinson disease, and pseudobulbar affect. A search of the literature was performed using the specific FDA-approved drug or drug classes in combination with the terms 'dermatologic,' 'cutaneous,' 'skin,' or 'rash.' Both PubMed and the Cochrane Database of Systematic Reviews were utilized, with side effects ranging from those cited in randomized controlled trials to case reports. It behooves neurologists, dermatologists, and primary care physicians to be aware of the recorded cutaneous adverse reactions and their severity for proper management and potential need to withdraw the offending medication.

    2011-01-01

    In this thesis I will give a formal definition of side effects. I will do so by modifying a system for modelling program instructions and program states, Quantified Dynamic Logic, to a system called DLAf (for Dynamic Logic with Assignments as Formulas), which in contrast to QDL allows assignments in formulas and makes use of short-circuit evaluation. I will show the underlying logic in those formulas to be a variant of short-circuit logic called repetition-proof short-circuit logic. Using DLAf I will define the actual and the expected evaluation of a single instruction. The side effects are then defined to be the difference between the two. I will give rules for composing those side effects in single instructions, thus scaling up our definition of side effects to a definition of side effects in deterministic \\dlaf-programs. Using this definition I will give a classification of side effects, introducing as most important class that of marginal side effects. Finally, I will show how to use our system for calcul...

    The molecular understanding of phenotypes caused by drugs in humans is essential for elucidating mechanisms of action and for developing personalized medicines. Side effects of drugs (also known as adverse drug reactions) are an important source of human phenotypic information, but so far research...... on this topic has been hampered by insufficient accessibility of data. Consequently, we have developed a public, computer-readable side effect resource (SIDER) that connects 888 drugs to 1450 side effect terms. It contains information on frequency in patients for one-third of the drug-side effect...... pairs. For 199 drugs, the side effect frequency of placebo administration could also be extracted. We illustrate the potential of SIDER with a number of analyses. The resource is freely available for academic research at http://sideeffects.embl.de....

    Full Text Available Ciprofloxacin is one of the most commonly used antibacterial agents with relatively few side effects. Serious adverse reactions reported with ciprofloxacin are rare with an incidence of 0.6%. Recently we came across two rare adverse effects of ciprofloxacin, viz. toxic epidermal necrolysis and agranulocytosis. To our knowledge, a total of seven cases have been reported in the literature documenting an association between oral ciprofloxacin administration and toxic epidermal necrolysis. One case of granulocytopenia, four of pancytopenia and fifteen of leucopenia worldwide have been reported. With the use of ciprofloxacin becoming more and more widespread, these two rare but fatal complications of ciprofloxacin should be borne in mind.

    Noise pollution from road traffic in residential areas is a growing environmental problem. New approaches to turn the negative trend are needed. The programme “Soundscape Support to Health” will achieve new knowledge about the adverse health effects of noise pollution on humans and will investigate the link between well-being and health and perceived soundscapes for optimizing the acoustic soundscapes in urban residential areas. This paper will briefly present the programme and presents preliminary results from the first study of how various adverse health effects are related to individual noise exposures among individuals in residential areas with and without access to a quiet side of the dwelling.

    2015-01-01

    The misuse of nootropics—any substance that may alter, improve, or augment cognitive performance, mainly through the stimulation or inhibition of certain neurotransmitters—may potentially be dangerous and deleterious to the human brain, and certain individuals with a history of mental or substance use disorders might be particularly vulnerable to their adverse effects. We describe four cases of probable nootropic-induced psychiatric adverse effects to illustrate this theory. To the best of our knowledge this has not been previously reported in the formal medical literature. We briefly describe the most common classes of nootropics, including their postulated or proven methods of actions, their desired effects, and their adverse side effects, and provide a brief discussion of the cases. Our objective is to raise awareness among physicians in general and psychiatrists and addiction specialists in particular of the potentially dangerous phenomenon of unsupervised nootropic use among young adults who may be especially vulnerable to nootropics’ negative effects.

    1992-01-01

    Single doses of nonprescription analgesics are commonly used to treat self-diagnosed conditions. To evaluate the safety of single doses of nonprescription-strength ibuprofen, we examined reported side effects from 15 double-blind, randomized, controlled trials we conducted of the drug to treat various common painful conditions (e.g., headache, sore throat). All studies included placebo and another nonprescription analgesic, acetaminophen. A total of 878 subjects received ibuprofen 200 or 400 mg, 849 acetaminophen 650 or 1000 mg, and 852 placebo. The overall frequency of side effects was comparable: ibuprofen 2.4%, acetaminophen 3.2%, and placebo 2.1%. The frequency of central nervous system symptoms was 0.8%, 2.1%, and 0.9%, respectively. Upper gastro-intestinal upset ranged from 0.8-0.9% of subjects in all groups. We conclude that single doses of nonprescription ibuprofen are well tolerated and demonstrate a side effect profile indistinguishable from that of acetaminophen and placebo. PMID:1437701

  20. Psychiatric Adverse Effects of Dermatological Drugs

    Directory of Open Access Journals (Sweden)

    Mine Özmen

    2010-07-01

    Full Text Available Dermatological drugs, mostly corticosteroids and isotretinoin, cause different psychiatric adverse effects. During steroid therapy, a wide range of psychiatric conditions, from minor clinical symptoms like insomnia and anxiety to serious psychiatric syndromes like psychosis and delirium might be seen. In medical literature, a causal connection is usually suggested between “isotretinoin”, which is used for treatment of acne vulgaris and depression and suicide attempts. However, there are no statistically significant double-blind randomized studies that support this connection. Clinicians must know patient’s psychiatric history before using any dermatological treatment known as causing psychiatric adverse effects, and psychiatric consultation should be established whenever necessary.

  1. Cardiac adverse effects of nicotine replacement therapy.

    Science.gov (United States)

    2015-12-01

    Smoking markedly increases the risk of cardiovascular disease. Nicotine replacement therapy is available to assist in smoking cessation. To assess the cardiac adverse effects of nicotine replacement therapy, we conducted a review of the literature using the standard Prescrire methodology. A meta-analysis of 21 randomised, placebo-controlled trials published in early 2014 included a total of 11 647 patients, including 828 patients at high risk of cardiovascular events and 187 patients with acute coronary disorders. It showed that nicotine replacement therapy was associated with an increased risk of cardiac disorders, particularly palpitations, which are a known adverse effect of smoking. Among patients at high cardiovascular risk, 1.2% experienced a serious cardiovascular event, with no statistically significant difference versus placebo. Bupropion and varenicline both have serious adverse effects and have been less extensively evaluated in patients at high cardiovascular risk. In practice, when a drug is needed to assist in smoking cessation, nicotine appears to be a reasonable choice. Nicotine replacement therapy exposes patients to a risk of palpitations but rarely to serious cardiac disorders, even in individuals with a cardiovascular history. In addition, these adverse effects are better documented than those of bupropion and varenidine in such patients. Nonetheless, the cardiac effects of nicotine call for prudent use of nicotine replacement therapy: the minimum effective dose should be sought, and the goal should be total nicotine withdrawal.

    2011-01-01

    Information related to adverse drug effects caused by ocular medications and ocular adverse effects of systemically administered drugs has increased over the last several decades. Here we review the medical literature over the last four decades to both quantitatively and qualitatively determine the adverse effects of ocular drugs and ocular toxicity of non-ocular drugs. A systematic bibliographic review of the literature was performed with the following terms: "drug treatment", "drug therapy", "ocular adverse effects", "ocular side effects", "ocular toxicity", "systemic side effects", "systemic adverse effects", "systemic toxicity", "ocular drug" and "ophthalmic drug" using the Boolean operators or, and, not. Searches focused on: (1) Ocular side/adverse effects of ophthalmic drugs; (2) Ocular side/adverse effects of systemic drugs; (3) Systemic side/adverse effects of ophthalmic drugs. PubMed was used to perform searches. Limits included: species, human and field tag, abstract/title, dates from 01/01/1971 to 31/12/2010. A sub-selection of references was made by discarding articles that were irrelevant for the topics listed above. Adverse effects of alpha2-adrenergic agonists, beta-adrenergic antagonists, quinine derivatives and antituberculosis agents appear in the literature throughout the period of the review. Adverse effects of newer drugs such as amiodarone, phosphodiesterase 5 inhibitors, antiepileptics, tamoxifen, and its interactions have been published principally in the last two decades. It is imperative for patient safety that knowledge of the adverse effects of drugs on the eye whether topically or systemically administered, and the possible systemic effects of drugs given as ophthalmic medications be emphasized to clinicians.

    Cytokines, currently known to be more than 130 in number, are small MW (aldesleukin (rhIL-2), oprelvekin (rhIL-11), filgrastim and tbo-filgrastim (rhG-CSF), sargramostim (rhGM-CSF), metreleptin (rh-leptin) and the rh-erythropoietins, epoetin and darbepoietin alfa. Anakinra, a recombinant receptor antagonist for IL-1, is in the IL-1 family; recombinant interferons alfa-1, alfa-2, beta-1 and gamma-1 make up the interferon family; palifermin (rhKGF) and becaplermin (rhPDGF) are in the PDGF family; and rhBMP-2 and rhBMP-7 represent the TGFβ family. The main physicochemical features, FDA-approved indications, modes of action and side effects of these approved cytokines are presented. Underlying each adverse events profile is their pleiotropism, potency and capacity to release other cytokines producing cytokine 'cocktails'. Side effects, some serious, occur despite cytokines being endogenous proteins, and this therefore demands caution in attempts to introduce individual members into the clinic. This caution is reflected in the relatively small number of cytokines currently approved by regulatory agencies and by the fact that 14 of the FDA-approved preparations carry warnings, with 10 being black box warnings.

    Full Text Available Human-computer interfaces often give rise to a variety of side effects, including eyestrain, headache, fatigue, and motion sickness (aka cybersickness, simulator sickness. We might hope that improvements in interface design would tend to reduce these side effects. Unfortunately, history reveals just the opposite: The incidence and severity of motion sickness (for example is positively related to the progressive sophistication of display technology and systems. In this presentation, I enquire about the future of interface technologies in relation to side effects. I review the types of side effects that occur and what is known about the causes of interface side effects. I suggest new ways of understanding relations between interface technologies and side effects, and new ways to approach the problem of interface side effects.

    Nearly two thirds of patients with cancer will undergo radiation therapy as part of their treatment plan. Given the increased use of radiation therapy and the growing number of cancer survivors, family physicians will increasingly care for patients experiencing adverse effects of radiation. Selective serotonin reuptake inhibitors have been shown to significantly improve symptoms of depression in patients undergoing chemotherapy, although they have little effect on cancer-related fatigue. Radiation dermatitis is treated with topical steroids and emollient creams. Skin washing with a mild, unscented soap is acceptable. Cardiovascular disease is a well-established adverse effect in patients receiving radiation therapy, although there are no consensus recommendations for cardiovascular screening in this population. Radiation pneumonitis is treated with oral prednisone and pentoxifylline. Radiation esophagitis is treated with dietary modification, proton pump inhibitors, promotility agents, and viscous lidocaine. Radiation-induced emesis is ameliorated with 5-hydroxytryptamine3 receptor antagonists and steroids. Symptomatic treatments for chronic radiation cystitis include anticholinergic agents and phenazopyridine. Sexual dysfunction from radiation therapy includes erectile dysfunction and vaginal stenosis, which are treated with phosphodiesterase type 5 inhibitors and vaginal dilators, respectively.

    Side effects of non-steroidal antirheumatic drugs (NSAD) may occur in any organ system, since the prostaglandins, the synthesis of which is inhibited by NSAD, play a role in numerous adverse cellular processes throughout the body. Besides these physiologic regulations there are adverse effects of NSAD, such as bone marrow aplasia, of unexplained etiology. The interactions of NSAD are of clinical relevance in drug types such as the salicylates, pyrazolons and fenamic acids (e.g. interactions with cumarin derivatives). The clinically relevant interactions of NSAD are discussed in detail. PMID:6982512

  11. Treatment side effects and follow-up of malignant melanoma

    International Nuclear Information System (INIS)

    Side effects in the therapy of malignant melanoma are primarily of importance for radiologists in advanced tumor stages. The available treatment options and their respective side effect profiles have undergone a profound change in recent years after the introduction of modern oncological therapies (e.g. immunotherapy and targeted therapy) with an increasing focus on individual tumor biology and differ significantly from those of classical chemotherapy. The immunotherapeutic agents, in particular ipilimumab, take on a special position because of their specific immune-mediated mechanisms of action and the associated side effects, so-called immune-related adverse events (irAE). The majority of the treatment effects are manifested on the skin (> 50 %) and are generally not detectable by diagnostic radiology. Only a comparatively small proportion of treatment side effects is detectable with diagnostic imaging (15-20 %) but as in the example of therapy-induced colitis with ipilimumab, may be rapidly fatal. In addition to colitis (10-20 %) further therapy side effects apparent in diagnostic imaging are hypophysitis (1.8-17 %), thyroiditis (0.8 %), myositis (1.7 %), fasciitis and sarcoid-like lymph node alterations (6.8 %). To detect radiologically detectable side effects early on and to delineate them especially from tumor progression and (opportunistic) infections, detailed knowledge of the therapeutic methods for melanoma, the mechanisms of action and in particular the sometimes very specific side effects is imperative for radiologists.

  12. The NAS Perchlorate Review: Adverse Effects?

    2005-11-01

    To the editor: Drs. Ginsberg and Rice argue that the reference dose for perchlorate of 0.0007 mg/kg per day recommended by the National Academies’ Committee to Assess the Health Implications of Perchlorate Ingestion is not adequately protective. As members of the committee, we disagree. Ginsberg and Rice base their conclusion on three points. The first involves the designation of the point of departure as a NOEL (no-observed-effect level) versus a LOAEL (lowest-observed-adverse- effect level). The committee chose as its point of departure a dose of perchlorate (0.007 mg/kg per day) that when given for 14 days to 7 normal subjects did not cause a significant decrease in the group mean thyroid iodide uptake (Greer et al. 2002). Accordingly, the committee considered it a NOEL. Ginsberg and Rice focus on the fact that only 7 subjects were given that dose, and they 1seem to say that attention should be paid only to the results in those subjects in whom there was a 1fall in thyroid iodide uptake, and that the results in those in whom there was no fall or an increase should be ignored. They consider the dose to be a LOAEL because of the fall in uptake in those few subjects. It is important to note that a statistically significant decrease of, for example, 5% or even 10%, would not be biologically important and, more important, would not be sustained. For example, in another study (Braverman et al. 2004), administration of 0.04 mg/kg per day to normal subjects for 6 months had no effect on thyroid iodide uptake when measured at 3 and 6 months, and no effect on serum thyroid hormone or thyrotropin concentrations measured monthly (inspection of Figure 5A in the paper by Greer et al. suggests that this dose would inhibit thyroid iodide uptake by about 25% if measured at 2 weeks). The second issue involves database uncertainty. In clinical studies, perchlorate has been administered prospectively to 68 normal subjects for 2 weeks to 6 months. In one study (Brabant et al. 1992

    In order to analyse the response of pharmaceutical companies to adverse drug reaction reports, 37 suspected side effects were sent by mail to the 30 companies concerned. The time period involved was 1 year and corresponded to a total of 3341 consultations in general practice. Companies answered in 29 cases (78.3%), sent 21 reply forms and returned 3 evaluations of adverse drugs reactions to the reporting doctor. The high percentage of adverse drug reactions (1.07 per one hundred consultations), the doctor's work-load and poor feed-back lead one to reflect on the usefulness of systematic adverse drug reaction reporting by general practitioners.

    Drug side effects levy a massive cost on society through drug failures, morbidity, and mortality cases every year, and their early detection is critically important. Here, we describe the array of model-based phenotype predictors (AMPP), an approach that leverages medical informatics resources and a human genome-scale metabolic model (GSMM) to predict drug side effects. AMPP is substantially predictive (AUC > 0.7) for >70 drug side effects, including very serious ones such as interstitial nephritis and extrapyramidal disorders. We evaluate AMPP's predictive signal through cross-validation, comparison across multiple versions of a side effects database, and co-occurrence analysis of drug side effect associations in scientific abstracts (hypergeometric p value = 2.2e-40). AMPP outperforms a previous biochemical structure-based method in predicting metabolically based side effects (aggregate AUC = 0.65 versus 0.59). Importantly, AMPP enables the identification of key metabolic reactions and biomarkers that are predictive of specific side effects. Taken together, this work lays a foundation for future detection of metabolically grounded side effects during early stages of drug development. PMID:27135366

    The beneficial and adverse effects of some chemopreventive agents, such as Vitamins A, C, E, beta-carotene, indole-3-carbinol, capsaicin, garlic, and aloe are reviewed. Two large randomized trials with a lung cancer endpoint, the Alpha-Tocopherol, Beta-Carotene (ATBC) Prevention Study and the Beta-Carotene and Retinol Efficacy Trial (CARET), suggested that antioxidants might be harmful in smokers. However, the results of the Linxian study and of the ATBC or the CARET studies were significantly different in this respect, and therefore, the relationship between antioxidant and carcinogenesis remains open to debate. Indole-3-carbinol has cancer promoting activities in the colon, thyroid, pancreas, and liver, whereas capsaicin alters the metabolism of chemical carcinogens and may promote carcinogenesis at high doses. Organosulfur compounds and selenium from garlic have no or a little enhancing effect on cancer promotion stage. Information upon chemopreventive mechanisms that inhibit carcinogenesis is imperfect, although the causes and natures of certain human cancers are known. Therefore, definitive preventive guidelines should be carefully offered for various types of tumors, which properly consider ethnic variations, and the efficacies and the safety of chemopreventive agents.

  19. Cadmium & its adverse effects on human health.

    Bernard, A

    2008-10-01

    Cadmium (Cd), a by-product of zinc production, is one of the most toxic elements to which man can be exposed at work or in the environment. Once absorbed, Cd is efficiently retained in the human body, in which it accumulates throughout life. Cd is primarily toxic to the kidney, especially to the proximal tubular cells, the main site of accumulation. Cd can also cause bone demineralization, either through direct bone damage or indirectly as a result of renal dysfunction. In the industry, excessive exposures to airborne Cd may impair lung function and increase the risk of lung cancer. All these effects have been described in populations with relatively high exposures to Cd in the industrial or in heavily polluted environments. Recent studies, however, suggest that the chronic low environmental exposure to Cd now prevailing in industrialized countries can adversely affect the kidneys and bones of the general population. These studies show consistent associations between various renal and bone biomarkers and the urinary excretion of Cd used to assess Cd body burden. The public health impact of these findings are still unknown. Further research is needed to ascertain that these associations are truly causal and not secondary to parallel changes in Cd metabolism and in the bone or kidney function occurring because of ageing or diseases unrelated to Cd exposure.

  20. Adverse effects of IgG therapy.

    Berger, Melvin

    2013-01-01

    IgG is widely used for patients with immune deficiencies and in a broad range of autoimmune and inflammatory disorders. Up to 40% of intravenous infusions of IgG may be associated with adverse effects (AEs), which are mostly uncomfortable or unpleasant but often are not serious. The most common infusion-related AE is headache. More serious reactions, including true anaphylaxis and anaphylactoid reactions, occur less frequently. Most reactions are related to the rate of infusion and can be prevented or treated just by slowing the infusion rate. Medications such as nonsteroidal anti-inflammatory drugs, antihistamines, or corticosteroids also may be helpful in preventing or treating these common AEs. IgA deficiency with the potential of IgG or IgE antibodies against IgA increases the risk of some AEs but should not be viewed as a contraindication if IgG therapy is needed. Potentially serious AEs include renal dysfunction and/or failure, thromboembolic events, and acute hemolysis. These events usually are multifactorial, related to combinations of constituents in the IgG product as well as risk factors for the recipient. Awareness of these factors should allow minimization of the risks and consequences of these AEs. Subcutaneous IgG is absorbed more slowly into the circulation and has a lower incidence of AEs, but awareness and diligence are necessary whenever IgG is administered. PMID:24565701

  1. Early and Late Side Effects Associated with Photo(chemotherapy

    Full Text Available Phototherapy (PUVA ve UVB is a widely used and effective treatment method for a variety of dermatological diseases. Adverse effects associated with phototherapy can be classified as acute and chronic side effects. Acute side effects are mostly related with UV doses and drug intolerance, and include itching, nausea, erythema, edema and phototoxic reactions that sometimes blister formation is seen. Acute side effects are usually moderate and transient. Chronic side effects of phototherapy are early aging of skin, pigmentary changes and increased risk of skin carcinogenesis. The major concern is development of skin cancer. This risk is especially related to long-term exposure and high cumulative doses of PUVA, increase in time and is persistent. Therefore, risk/advantage ratio of phototherapy should be carefully evaluated in each patient, and treatment protocols with minimal UV exposure should be chosen according to the phototherapy guides. Follow-up of the patients for long terms is important in prevention or in reduction of this risk by detecting and treating any premalignant or malignant lesion early. In this article, acute and chronic side effects of phototherapy are reviewed with recent literature findings.

Polydipsia and polyuria developed in each species, but were greater and persisted longer in the cockatoos. Peak water intake in the cockatoos more than quadrupled, and remained increased for 23 days after cessation of gentamicin administration. Plasma aspartate transaminase activity increased significantly (P less than 0.05) after treatment in the macaws, and plasma aspartate transaminase and lactate dehydrogenase activities increased in the cockatoos. Single IM administration of gentamicin (5 mg/kg) resulted in mean (+/- SEM) plasma concentration of 20.6 (+/- 1.85) micrograms/ml at 0.5 hour for either species of birds. There were no significant differences between mean plasma gentamicin concentrations for cockatoos and macaws at any time after drug administration, except at 12 hours, when values for cockatoos were significantly (P less than 0.05) greater than those for macaws. The elimination half-life for gentamicin after IM administration of 5 and 10 mg/kg was 1.17 and 1.07 hours, respectively, for macaws and 1.23 and 1.44 hours, respectively, for cockatoos. Correlation between drug disposition and adverse side effects could not be detected. PMID:2316918

    Triptans are the treatment of choice for acute migraine. While seemingly a homogenous group of drugs, results from a meta-analysis reveal significant differences in efficacy and tolerability among oral triptans. The incidence of drug-related central nervous system (CNS) side-effects with some triptans is as high as 15% and may be associated with functional impairment and reduced productivity. The occurrence of adverse events associated with triptans in general, and CNS side-effects in particular, may lead to a delay in initiating or even avoidance of an otherwise effective treatment. Potential explanations for differences among triptans in the incidence of CNS side-effects may relate to pharmacological and pharmacokinetic differences, including receptor binding, lipophilicity, and the presence of active metabolites. Of the triptans reviewed, at clinically relevant doses, almotriptan 12.5 mg, naratriptan 2.5 mg and sumatriptan 50 mg had the lowest incidence of CNS side-effects, while eletriptan 40 and 80 mg, rizatriptan 10 mg and zolmitriptan 2.5 and 5 mg had the highest incidence. The most likely explanations for the differences in CNS side-effects among triptans are the presence of active metabolites and high lipophilicity of the parent compound and active metabolites. Eletriptan, rizatriptan and zolmitriptan have active metabolites, while lipophilicity is lowest for almotriptan and sumatriptan. If CNS side-effects are a clinically relevant concern in the individual patient, use of a triptan with a low incidence of CNS side-effects may offer the potential for earlier initiation of treatment and more effective outcomes.

    The majority of psychotropic drugs entail sexual side effects. The sexual side effects may reduce quality of life and may give rise to non-compliance. For example, 30-60 per cent of patients treated with antidepressants are known to develop a sexual dysfunction. However, some psychotropic drugs...... with no or very few sexual side effects have begun to emerge. The treatment of sexual side effects induced by psychotropic drugs may consist of: modified sexual habits, reduction in dosage, switching to another medication, possibly in combination with different psychotropic agents, other varieties of...... pharmacologically active substances or specific products for the treatment of sexual dysfunction such as sildenafil. Above all, it should be acknowledged that relatively few data are available in this field and in particular that there is a lack of controlled studies....

  8. Adverse effects of drugs on the immature kidney.

    Guignard, J P; Gouyon, J B

    1988-01-01

    The immature kidney may be adversely affected by a variety of vasoactive or diuretic drugs, either administered to the mother during pregnancy, or to the neonate. Inhibitors of the angiotensin-converting enzyme administered to the hypertensive pregnant woman can severely and sometimes definitely impair renal function in the fetus, leading to postnatal anuria. Pathogenesis involves interference with the renin-angiotensin system and the prostaglandins. Beta-adrenergic agents administered during labor depress glomerular filtration rate transiently. Tolazoline, an alpha-adrenergic blocking agent useful in the treatment of persistent pulmonary hypertension of the neonate induces intense renal vasoconstriction with consequent hypoperfusion. Indomethacin, a prostaglandin synthetase inhibitor used for the pharmacological closure of a patent ductus arteriosus, also increases renal vascular resistance, and decreases urine output. Furosemide, the drug most often used in oliguric neonates, may also adversely affect the newborn infant. Its use has been associated with an increase in the incidence of patent ductus arteriosus, hypercalciuria, nephrocalcinosis and secondary hyperparathyroidism. These observations demonstrate that the proper use of drugs requires that the therapeutic endpoint be clearly defined and the predictable side effects be anticipated. PMID:2901276

    Full Text Available Background: Bevacizumab a recombinant humanized monoclonal antibody was approved in 2004 by US FDA for metastatic colorectal cancer. It is reported to cause potentially serious toxicities including severe hypertension, proteinuria, and congestive heart failure. Aim: To correlate adverse event tetany with the use of bevacizumab. Materials and Methods : World Health Organization′s Uppsala Monitoring Centre, Sweden, for reporting of adverse drug reactions from all over the world, identified 7 cases with tetany-related symptoms to bevacizumab from four different countries. These 7 patients reported to UMC database developed adverse events described as musculoskeletal stiffness (1, muscle spasm (1, muscle cramps (1, lock jaw or jaw stiffness (4, and hypertonia (1, with hypocalcaemia. Results: After detailed study of the possible mechanism of actions of bevacizumab and factors causing tetany, it is proposed that there is a possibility of tetany by bevacizumab, which may occur by interfering with calcium metabolism. Resorption of bone through osteoclasts by affecting VEGF may interfere with calcium metabolism. Another possibility of tetany may be due to associated hypomagnesaemia, hypokalemia, or hyponatremia. Conclusions: Tetany should be considered as a one of the signs. Patient on bevacizumab should carefully watch for tetany-related symptoms and calcium and magnesium levels for their safety.

    2013-07-01

    Human immunoglobulin (IG) is used for IgG replacement therapy in primary and secondary immunodeficiency, for prevention and treatment of certain infections, and as an immunomodulatory agent for autoimmune and inflammatory disorders. IG has a wide spectrum of antibodies to microbial and human antigens. Several high-titered IGs are also available enriched in antibodies to specific viruses or bacterial toxins. IG can be given intravenously (IGIV), intramuscularly (IGIM) or by subcutaneous infusions (SCIG). Local adverse reactions such as persistent pain, bruising, swelling and erythema are rare with IGIV infusions but common (75%) with SCIG infusions. By contrast, adverse systemic reactions are rare with SCIG infusions but common with IGIV infusions, occurring as often as 20% to 50% of patients and 5% to 15% of all IGIV infusions. Systemic adverse reactions can be immediate (60% of reactions) occurring within 6 hours of an infusion, delayed (40% of reactions) occurring 6 hours-1 week after an infusion, and late (less than 1% of reactions), occurring weeks and months after an infusion. Immediate systemic reactions such as head and body aches, chills and fever are usually mild and readily treatable. Immediate anaphylactic and anaphylactoid reactions are uncommon. The most common delayed systemic reaction is persistent headache. Less common but more serious delayed reactions include aseptic meningitis, renal failure, thromboembolism, and hemolytic reactions. Late reactions are uncommon but often severe, and include lung disease, enteritis, dermatologic disorders and infectious diseases. The types, incidence, causes, prevention, and management of these reactions are discussed. PMID:23835249

    Objective The study tested the performance of adverse effects search filters when searching for safety information on medical devices, procedures, and diagnostic tests in MEDLINE and Embase. Methods The sensitivity of 3 filters was determined using a sample of 631 references from 131 rapid reviews related to the safety of health technologies. The references were divided into 2 sets by type of intervention: drugs and nondrug health technologies. Keyword and indexing analysis were performed on references from the nondrug testing set that 1 or more of the filters did not retrieve. Results For all 3 filters, sensitivity was lower for nondrug health technologies (ranging from 53%–87%) than for drugs (88%–93%) in both databases. When tested on the nondrug health technologies set, sensitivity was lower in Embase (ranging from 53%–81%) than in MEDLINE (67%–87%) for all filters. Of the nondrug records that 1 or more of the filters missed, 39% of the missed MEDLINE records and 18% of the missed Embase records did not contain any indexing terms related to adverse events. Analyzing the titles and abstracts of nondrug records that were missed by any 1 filter, the most commonly used keywords related to adverse effects were: risk, complications, mortality, contamination, hemorrhage, and failure. Conclusions In this study, adverse effects filters were less effective at finding information about the safety of medical devices, procedures, and tests compared to information about the safety of drugs.

    Therapy by human immunoglobulin G (IgG) concentrates is a success story ongoing for decades with an ever increasing demand for this plasma product. The success of IgG concentrates on a clinical level is documented by the slowly increasing number of registered indication and the more rapid increase of the off-label uses, a topic dealt with in another contribution to this special issue of Frontiers in Immunology. A part of the success is the adverse event (AE) profile of IgG concentrates which is, even at life-long need for therapy, excellent. Transmission of pathogens in the last decade could be entirely controlled through the antecedent introduction by authorities of a regulatory network and installing quality standards by the plasma fractionation industry. The cornerstone of the regulatory network is current good manufacturing practice. Non-infectious AEs occur rarely and mainly are mild to moderate. However, in recent times, the increase in frequency of hemolytic and thrombotic AEs raised worrying questions on the possible background for these AEs. Below, we review elements of non-infectious AEs, and particularly focus on hemolysis and thrombosis. We discuss how the introduction of plasma fractionation by ion-exchange chromatography and polishing by immunoaffinity chromatographic steps might alter repertoire of specificities and influence AE profiles and efficacy of IgG concentrates.

  16. The Social Side Effects of Acetaminophen

    Science.gov (United States)

    Mischkowski, Dominik

    About 23% of all adults in the US take acetaminophen during an average week (Kaufman, Kelly, Rosenberg, Anderson, & Mitchell, 2002) because acetaminophen is an effective physical painkiller and easily accessible over the counter. The physiological side effects of acetaminophen are well documented and generally mild when acetaminophen is consumed in the appropriate dosage. In contrast, the psychological and social side effects of acetaminophen are largely unknown. Recent functional neuroimaging research suggests that the experience of physical pain is fundamentally related to the experience of empathy for the pain of other people, indicating that pharmacologically reducing responsiveness to physical pain also reduces cognitive, affective, and behavioral responsiveness to the pain of others. I tested this hypothesis across three double-blind between-subjects drug intervention studies. Two experiments showed that acetaminophen had moderate effects on empathic affect, specifically personal distress and empathic concern, and a small effect on empathic cognition, specifically perceived pain, when facing physical and social pain of others. The same two experiments and a third experiment also showed that acetaminophen can increase the willingness to inflict pain on other people, i.e., actual aggressive behavior. This effect was especially pronounced among people low in dispositional empathic concern. Together, these findings suggest that the physical pain system is more involved in the regulation of social cognition, affect, and behavior than previously assumed and that the experience of physical pain and responsiveness to the pain of others share a common neurochemical basis. Furthermore, these findings suggest that acetaminophen has unappreciated but serious social side effects, and that these side effects may depend on psychological characteristics of the drug consumer. This idea is consistent with recent theory and research on the context-dependency of neurochemical

    (131)I, when released in a radiological or nuclear accident as happened recently in Fukushima, Japan, may cause thyroid cancer as a long-term consequence. Iodine thyroid blocking (ITB) is known to reduce the risk of developing thyroid cancer. Potential adverse effects of ITB have not been systematically investigated so far. This article summarises the results of a review on adverse effects of ITB based on a systematic literature search in scientific medical databases. A meta-analysis was not performed as identified studies displayed major heterogeneity. The search resulted in 14 articles relevant to the topic, reporting mostly on surveys, ecological and intervention studies. Only one study from Poland focused on effects (both desired and adverse) of an ITB intervention following the Chernobyl accident. All other studies reported on iodine administration in a different context. Overall, the studies did not reveal severe adverse reactions to potassium iodide in the general public. Since ITB is a protective measure only applied in very specific circumstances, scientifically sound studies of adverse effects are scarce and consequently the evidence base is weak. The assessment of adverse effects of ITB relies on indirect evidence from related areas. This study may contribute to ongoing developments in pharmacoepidemiology aiming to better quantify adverse effects of medications and health care interventions including ITB. PMID:22021061

    2007-07-01

    Full Text Available Abstract Background As every healthcare intervention carries some risk of harm, clinical decision making needs to be supported by a systematic assessment of the balance of benefit to harm. A systematic review that considers only the favourable outcomes of an intervention, without also assessing the adverse effects, can mislead by introducing a bias favouring the intervention. Much of the current guidance on systematic reviews is directed towards the evaluation of effectiveness; but this differs in important ways from the methods used in assessing the safety and tolerability of an intervention. A detailed discussion of why, how and when to include adverse effects in a systematic review, is required. Methods This discussion paper, which presupposes a basic knowledge of systematic review methodology, was developed by consensus among experienced reviewers, members of the Adverse Effects Subgroup of The Cochrane Collaboration, and supplemented by a consultation of content experts in reviews methodology, as well as those working in drug safety. Results A logical framework for making decisions in reviews that incorporate adverse effects is provided. We explore situations where a comprehensive investigation of adverse effects is warranted and suggest strategies to identify practicable and clinically useful outcomes. The advantages and disadvantages of including observational and experimental study designs are reviewed. The consequences of including separate studies for intended and unintended effects are explained. Detailed advice is given on designing electronic searches for studies with adverse effects data. Reviewers of adverse effects are given general guidance on the assessment of study bias, data collection, analysis, presentation and the interpretation of harms in a systematic review. Conclusion Readers need to be able to recognize how strategic choices made in the review process determine what harms are found, and how the findings may affect

    This overview of systematic reviews (SRs) aims to evaluate critically the evidence regarding the adverse effects of herbal medicines (HMs). Five electronic databases were searched to identify all relevant SRs, with 50 SRs of 50 different HMs meeting our inclusion criteria. Most had only minor weaknesses in methods. Serious adverse effects were noted only for four HMs: Herbae pulvis standardisatus, Larrea tridentate, Piper methysticum and Cassia senna. The most severe adverse effects were liver or kidney damage, colon perforation, carcinoma, coma and death. Moderately severe adverse effects were noted for 15 HMs: Pelargonium sidoides, Perna canaliculus, Aloe vera, Mentha piperita, Medicago sativa, Cimicifuga racemosa, Caulophyllum thalictroides, Serenoa repens, Taraxacum officinale, Camellia sinensis, Commifora mukul, Hoodia gordonii, Viscum album, Trifolium pratense and Stevia rebaudiana. Minor adverse effects were noted for 31 HMs: Thymus vulgaris, Lavandula angustifolia Miller, Boswellia serrata, Calendula officinalis, Harpagophytum procumbens, Panax ginseng, Vitex agnus-castus, Crataegus spp., Cinnamomum spp., Petasites hybridus, Agave americana, Hypericum perforatum, Echinacea spp., Silybum marianum, Capsicum spp., Genus phyllanthus, Ginkgo biloba, Valeriana officinalis, Hippocastanaceae, Melissa officinalis, Trigonella foenum-graecum, Lagerstroemia speciosa, Cnicus benedictus, Salvia hispanica, Vaccinium myrtillus, Mentha spicata, Rosmarinus officinalis, Crocus sativus, Gymnema sylvestre, Morinda citrifolia and Curcuma longa.

Pain in the elderly population is especially difficult given the myriad of physiological, pharmacological, and psychological aspects of caring for the geriatric patient. Opiates are the mainstay of pain treatment throughout all age groups but special attention must be paid to the efficacy and side effects of these powerful drugs when prescribing to a population with impaired metabolism, excretion and physical reserve. In a random chart review of 300 US veterans, 44% of those receiving an analgesic also received opioids. The increasing use of opiates for pain management by healthcare practitioners requires that those prescribing opioids be aware of the special considerations for treating the elderly. This article will address the precautions one must take when using opiates in the geriatric population, as well as the side effects and ways to minimize them.Keywords: opiates, pain, elderly, side effects

    Although in the last two decades the World Health Organization (WHO) has introduced tuberculosis as “a threat to global”, the vaccination with the Mycobacterium bovis Bacillus Calmette-Guerin (BCG) is the only way for the prevention of this fatal infectious disease. Despite of the efficacy of BCG vaccine especially against infants’ meningitis, it has still some limitations due to a variety of adverse effects. Many studies have evaluated the side effects of different strains of BCG vaccines in different countries. In Iran, some studies have been done so far to evaluate the adverse effects of 1173 P2 strain which is used for BCG vaccination. Each of these studies have used different standardization and sampling methods. This review will survey all studies that have been published about adverse effects of 1173 P2 strain of BCG vaccine in Iran using data mining methods.

    The effects of poor lighting and glare on public safety are well-known, as are the harmful environmental effects on various species and the environment in general. What is less well-known is the potential harmful medical effects of excessive poor nighttime lighting. A significant body of research has been developed over the last few years regarding this problem. One of the most significant effects is the startling increased risk for breast cancer by excessive exposure to nighttime lighting. The mechanism is felt to be by disruption of the circadian rhythm and suppression of melatonin production from the pineal gland. Melatonin has an anticancer effect that is lost when its production is disrupted. I am in the process of developing a monograph that will summarize this important body of research, to be presented and endorsed by the American Medical Association, and its Council of Science and Public health. This paper is a brief overall summary of this little known potential harmful effect of poor and excessive nighttime lighting.

    The use of wood stoves has increased greatly in the past decade, causing concern in many communities about the health effects of wood smoke. Wood smoke is known to contain such compounds as carbon monoxide, nitrogen oxides, sulfur oxides, aldehydes, polycyclic aromatic hydrocarbons, and fine respirable particulate matter. All of these have been shown to cause deleterious physiologic responses in laboratory studies in humans. Some compounds found in wood smoke--benzo(a)pyrene and formaldehyde--are possible human carcinogens. Fine particulate matter has been associated with decreased pulmonary function in children and with increased chronic lung disease in Nepal, where exposure to very high amounts of wood smoke occurs in residences. Wood smoke fumes, taken from both outdoor and indoor samples, have shown mutagenic activity in short-term bioassay tests. Because of the potential health effects of wood smoke, exposure to this source of air pollution should be minimal.29 references.

    Inhaled, intranasal, and cutaneous steroids are prescribed by physicians for a plethora of disease processes including asthma and rhinitis. While the high efficacy of this class of medication is well known, the wide range of adverse effects, both local and systemic, is not well elucidated. It is imperative to monitor total steroid burden in its varied forms as well as tracking for possible side effects that may be caused by a high cumulative dose of steroids. This review article highlights the adverse effects of different steroid modalities as well as suggests a monitoring tool to determine steroid totality and side effects. PMID:27207481

    Full Text Available Background: Misuse of topical corticosteroids is a widespread phenomenon among young people in India, especially women. The practice is associated with significant adverse effects and poor awareness of these effects among the general public. Aim: This study was conducted to examine the misuse and adverse effects of topical corticosteroids among the people in Bastar region in Chhattisgarh state of India. Materials and Methods: Data collected from patients presenting with at least one of the adverse effects of topical corticosteroids as the chief complaint, from November 2010 to October 2011. Results: Out of the 6723 new patients, 379 (5.63% had presented with misuse and adverse effects of topical corticosteroids, of whom 78.89% were females. More than 65% of the patients were in the age group 10-29 years. The main reason for using the topical corticosteroids was to lighten skin colour and treat melasma and suntan. Acne (37.99% and telangiectasia (18.99% were the most common adverse effects noted. Conclusions: Misuse of topical corticosteroids has a huge impact on dermatological practice, leading to a significant proportion of visits to the dermatologist. This hydra-headed problem needs multi-dimensional interventions, involving educational, legal and managerial approaches with cooperation from different sectors of society.

    Full Text Available Introduction: The use of nutritional supplements is prevalent among physical exercise practitioners and some adverse effects have been reported, however not sufficiently substantial, because they originate from isolated cases. Objectives: Investigate nutritional supplements consumption prevalence and adverse effects of the use of such products. Methods: An epidemiological, representative and transversal study, with 180 physical exercise practitioners in gyms, who answered questionnaires about sports supplementation, associated factors and self-perceived adverse effects. In a subsample of 86 individuals, blood pressure was measured and blood was collected for the evaluation of lipid profile markers, hepatic and renal function. Results: The supplementation prevalence level was 58.3%, whereas the physicians and nutritionists indicated only 21.9%. The reported adverse effects were observed only by supplement users (acne, insomnia, aggressiveness, headaches and tachycardia. Systolic blood pressure was higher in the supplemented group when compared to the control group (p = 0.04, as in the subgroup of thermogenic users (p < 0.0001 and among those who had consumed any type of supplementation for over 2 years (p = 0.005. Serum creatinine levels were higher only in the subgroup of carbohydrates when compared to the control group (p = 0.03. Diastolic blood pressure, lipid profile and hepatic function did not present differences between groups. Conclusions: The use of nutritional supplements without specialized orientation was elevated among physical exercise practitioners, being associated to adverse effects both by the users themselves and by clinical diagnosis.

  1. Adverse effects and treatment on palliative radiotherapy for bone metastases

    International Nuclear Information System (INIS)

    Adverse effects on palliative radiotherapy for bone metastases are generally mild. Acute and late adverse effects are similar between 8 Gy single fraction and multi-fraction radiotherapy (e.g. 30 Gy in 10 fractions). Both external beam radiotherapy and radiopharmaceutical therapy with strontium-89 may cause pain flare. A randomized controlled trial is currently performed to confirm the effectiveness of dexamethasone for the prevention of pain flare. Reirradiation for the same site is widely used. However, its safeness has not been confirmed enough. Radiation myelitis is an unrecoverable severe adverse effect. However, the tolerated accumulated dose for the spinal cord is not fully understood. Stereotactic body radiotherapy may be considered to deliver reirradiation for spinal metastases without exposing too much dose for the spinal cord. Another solution to prevent radiation myelitis after reirradiation may use dose fractionations of 8 Gy single or 20 Gy in 5 fractions instead of 30 Gy in 10 fractions. (author)

  2. Adverse effects of 131I therapy for differentiated thyroid cancer

    International Nuclear Information System (INIS)

    DTC is considered the most common endocrine neoplasm, and 131I therapy has been proven to be an important component in the management strategy. Currently, most research focuses on the adverse effects of radiation exposure to 131I therapy. Some results, based on large-scale and long-term investigation,show new information. Although 131I therapies are usually well tolerated, clinicians involved in the management of DTC need to be aware of the potential toxicity of 131I and take all measures to reduce these effects to a minimum. The aim of this review is to present the adverse effects of 131I therapy for DTC. (authors)

    A 16-year-old Caucasian female presented to the pulmonary clinic for a followup on her asthma. Due to the worsening of allergy-related symptoms, therapy with montelukast 10 mg daily was started and resulted in good relief of the patient's symptoms. In the nights following initiating therapy with montelukast, the patient's mother reported daily parasomnias in the form of sleeptalking and sleepwalking. Montelukast was discontinued, and that resulted in absence of the parasomnias. In a second attempt montelukast was reinstituted to control the patient's symptoms. Parasomnias were immediately reported after resuming therapy. Montelukast was then discontinued indefinitely. Our patient has never had any history of parasomnias, and since the discontinuation of montelukast, parasomnias were never reported again. Parasomnias in the form of sleeptalking or sleepwalking were not previously reported as adverse effects of montelukast. Alternative modalities to treat allergy-related symptoms in patients, who develop parasomnias while receiving montelukast, should be explored. PMID:24093069

    WHO defined in 1976 psychopharmaca as drugs affecting psychological functions, behaviour and self-perception. Psychopharmacology is the study of pharmacological agents that affect mental and emotional functions. Creative approach to psychopharmacotherapy reflects a transdisciplinary, integrative and person-centered psychiatry. Psychiatric disorders often occur in cardiac patients and can affect the clinical presentation and morbidity. Cardiovascular (CV) side effects (SE) caused by psychopharmaceutic agents require comprehensive attention. Therapeutic approach can increase placebo and decrease nocebo reactions. The main purpose of this review is to comprehend CV SE of psychotropic drugs (PD). Critical overview of CV SE of PD will be presented in this review. Search was directed but not limited to CV effects of psychopharmacological substances, namely antipsychotics, anxiolytics, hypnotics, sedatives, antidepressants and stimulants. Literature review was performed and data identified by searches of Medline and PubMed for period from 2004 to 2015. Only full articles and abstracts published in English were included. SE of PD are organized according to the following types of CV effects: cardiac and circulatory effects, abnormalities of cardiac repolarisation and arrhythmias and heart muscle disease. There is wide spectrum and various CV effects of PD. Results of this review are based on literature research. The reviewed data came largely from prevalence studies, case reports, and cross-sectional studies. Psychopharmacotherapy of psychiatric disorders is complex and when concomitantly present with CV disease, presentation of drug SEs can significantly contribute to illness course. Further development of creative psychopharmacotherapy is required to deal with CV effects of PD. PMID:27352209

    2008-03-01

    Full Text Available Dental amalgam is an alloy composed of mixture of approximately equal parts of elemental liquid mercury and an alloy powder. The popularity of amalgam arises from excellent long term performance, ease of use and low cost. Despite the popularity of dental amalgam as restorative material, there have been concerns regarding the potential adverse health and environmental effects arising from exposure to mercury in amalgam. They have long been believed to be of little significance as contributors to the overall body burden of mercury, because the elemental form of mercury is rapidly consumed in the setting reaction of the restoration. In 1997, 80% of dentist in Indonesia still using amalgam as an alternative material, and 60% of them treat the rest of unused amalgam carelessly. In recent years, the possible environmental and health impact caused by certain routines in dental practice has attracted attention among regulators. As part of point source reduction strategies, the discharge of mercury/amalgam-contaminated wastes has been regulated in a number of countries, even though it has been documented that by adopting appropriate mercury hygiene measures, the impact of amalgam use in dentistry is minimal. The purpose of this paper is to examine on studies that relate mercury levels in human to the presence of dental amalgams. It is concluded that even though mercury used in filling is hazardous, if normal occupational recommendations for proper mercury hygiene routines and source of reduction strategies are followed, no occupational health risk can be assumed.

    Yevgeny Botanov

    Full Text Available Despite the emergence of numerous clinical and non-clinical applications of bright light therapy (LT in recent decades, the prevalence and severity of LT side effects have not yet been fully explicated. A few adverse LT effects-headache, eye strain, irritability, and nausea-have been consistently reported among depressed individuals and other psychiatric cohorts, but there exists little published evidence regarding LT side effects in non-clinical populations, who often undergo LT treatment of considerably briefer duration. Accordingly, in the present study we examined, in a randomized sample of healthy young adults, the acute side effects of exposure to a single 30-minute session of bright white light (10,000 lux versus dim red light (< 500 lux. Across a broad range of potential side effects, repeated-measures analyses of variance revealed no significant group-by-time (Pre, Post interactions. In other words, bright light exposure was not associated with a significantly higher incidence of any reported side effect than was the placebo control condition. Nevertheless, small but statistically significant increases in both eye strain and blurred vision were observed among both the LT and control groups. Overall, these results suggest that the relatively common occurrence of adverse side effects observed in the extant LT literature may not fully extend to non-clinical populations, especially for healthy young adults undergoing LT for a brief duration.

    A 47 year old patient has been treated for psychotic depression for the last 5 years. The illness began manifesting through the symptoms of depressive thoughts, intrapsychic tension, projectivity, derealisation phenomena and pre-psychotic fears. She was treated with a combination of antidepressives, anxiolitics and hypnotics in ambulatory conditions. The therapy applied did not obtain the effects expected due to which an atypical antipsychotic was administered subsequently - risperidone, a 2 mg dose in the evening. After commencing the antipsychotic treatment, the symptoms started to weaken and a steady remission was obtained. Two years after a regular risperidone administration (in combination with fluoxetine, alprazolam and flurazepam) the patient reported some "bleeding" in October 2006. Hormonal blood tests were performed and high prolactin values were registered (2567.0 mIJ/L),due to which a gradual risperidone retractement was indicated. Medicamentous hyperprolactinaemia is a well known side effect of risperidone. A gradual risperidone retractement lead to a lowered and normal prolactin level within a month. PMID:20305606

  20. Categories of adverse health effects from indoor air pollution

    International Nuclear Information System (INIS)

    There is a lack of precision in the definition of health, which leads to confusion in the assessment of adverse effects arising from indoor air pollution. Adverse health effects range from annoyance to life-threatening conditions. Survey responses suggest that males and females differ in their perception of a healthy person, but both sexes envisage a male in terms of positive fitness, strength, energy and the possession of an athletic body, rather than how long one was likely to live. Psychological fitness was relatively unimportant in describing the health of others, but was rates as very important with respect to one's own health. Mortality statistics tend to obscure the proportion of the population who suffer chronic illness that is not life threatening. Although health is largely determined by genetic constitution, lifestyle and environmental factors, the morale of an individual is also important. A new classification of the adverse effects on health of indoor air pollution is proposed: this includes 'comfort' responses, such as sick building syndrome (category 1); acute chemical effects, the nature of which depends upon the specific intoxicant (category 2B), and perceived chronic grave risk, including cancer causation (category 3). The magnitude of risk in this latter category is imprecise, because its measurement involves the technique of quantitative risk assessment. (author) 1 fig., 2 tabs., 158 refs

    The study was conducted to compare the side effects in myelography of the two non-ionic water-soluble contrast medias, lopamidol (Niopam) and Metrizamide (Amipaque). A total of 111 patients were examined, 64 with lopamidol and 47 with Metrizamide. Side effects consisted of headache, nausea, vomiting, dizziness, urinary difficulty, muscular pain, seizure, neurobehavioral disturbance, neurological sign change, vital sign change and etc. The common side effects were headache, nausea, vomiting and dizziness in order of frequency. Most of the side effects were subsided within 24 hours following myelography. lopamidol myelography caused fewer and milder side effects than Metrizamide study. The side effects were more commonly observed in cervical, thoracic or total myelography than in lumbar myelography with either lopamidol or Metrizamide. There was no significant correlation between incidence of the side effects and premedication with phenobarbital or valium injection before myelography and CSF sampling during the procedure.

    Full Text Available Topiramate, an antiepileptic drug is reported to cause various ocular adverse effects like acute onset myopia, glaucoma. Visual field defect is an uncommon, serious treatment emergent adverse effect. We are reporting two cases of suspected topiramate induced visual field defects. Both the cases were on topiramate for more than 6 months as add-on therapy at daily doses ranging from 100-150mg. The presenting complaints were insidious onset visual disturbances. Diagnosis was based of temporal association with drug intake, clinical examination and investigations. Automated perimetry revealed bilateral superior quadrantic and arcuate field defects in the two cases respectively. Marked improvement with drug dechallenge was noted which was also corroborated by perimetry. Using Naranjo′s ADR Probability Scale, both cases revealed a "probable" association with topiramate. This report intends to improve awareness amongst clinicians to facilitate early diagnosis and intervention.

    Since the 1970s anabolic androgenic steroids (AAS) have been abused at ever increasing rates in competitive athletics, in recreational sports and in bodybuilding. Exceedingly high doses are often consumed over long periods, in particular by bodybuilders, causing acute or chronic adverse side effects frequently complicated by additional polypharmacy. This review summarizes side effects on non-reproductive organs and functions; effects on male and female reproduction have been recently reviewed in a parallel paper. Among the most striking AAS side effects are increases in haematocrit and coagulation causing thromboembolism, intracardiac thrombosis and stroke as well as other cardiac disturbances including arrhythmias, cardiomyopathies and possibly sudden death. 17α-alkylated AAS are liver toxic leading to cholestasis, peliosis, adenomas and carcinomas. Hyperbilirubinaemia can cause cholemic nephrosis and kidney failure. AAS abuse may induce exaggerated self-confidence, reckless behavior, aggressiveness and psychotic symptoms. AAS withdrawal may be accompanied by depression and suicidal intentions. Since AAS abuse is not or only reluctantly admitted physicians should be aware of the multitude of serious side effects when confronted with unclear symptoms. PMID:26373946

  7. Clinical side effects during aerosol therapy: cutaneous and ocular effects.

    Aerosolized medications maximize clinical benefit by targeting the airways and minimize side effects by reducing (though not eliminating) systemic exposure. Aerosolized drugs delivered with a facemask may inadvertently deposit on the face and in the eyes, raising concerns about cutaneous and ocular side effects with these drugs. Cases of anisocoria have been reported from exposure of the eyes to aerosol bronchodilators. Whether inhaled corticosteroids (ICS) can cause skin and eye problems like those seen with systemic or topical steroids is more difficult to answer. Patients who take ICS may have other corticosteroid exposures, or have other conditions that predispose them to side effects, making the analysis of the ICS risk challenging. Also, many studies were not designed to search for cutaneous or ocular effects, or may have been too short to detect these effects. Nevertheless, ICS have been associated with an increased risk of skin thinning, bruising, cataracts and possibly glaucoma in adults, but not in children. The risks increase with advanced age, higher doses, and longer duration of use. In children, the risks of cataracts and glaucoma were negligible with ICS, whether a mouthpiece or a mask interface was used. Side effects like skin rash and conjunctivitis occurred at low frequencies similar to placebo or comparator drugs. We do not know whether exposed children will have increased risks from ICS later in life. Therefore, it is wise to avoid face and eye deposition when possible, and to use the minimally effective dose. PMID:17411401

    Full Text Available Objective: To provide a frame to estimate the systemic impact (side/adverse events of (novel therapeutic targets by taking into consideration drugs potential on the numerous districts involved in rheumatoid arthritis (RA from the inflammatory and immune response to the gut-intestinal (GI microbiome.Methods: We curated the collection of molecules from high-throughput screens of diverse (multi-omic biochemical origin, experimentally associated to RA. Starting from such collection we generated RA-related protein-protein interaction (PPI networks (interactomes based on experimental PPI data. Pharmacological treatment simulation, topological and functional analyses were further run to gain insight into the proteins most affected by therapy and by multi-omic modelling.Results: Simulation on the administration of MTX results in the activation of expected (apoptosis and adverse (nitrogenous metabolism alteration effects. Growth factor receptor-bound protein 2 (GRB2 and Interleukin-1 Receptor Associated Kinase-4 (IRAK4, already an RA target emerge as relevant nodes. The former controls the activation of inflammatory, proliferative and degenerative pathways in host and pathogens. The latter controls immune alterations and blocks innate response to pathogens.Conclusions: This multi-omic map properly recollects in a single analytical picture known, yet complex, information like the adverse/side effects of MTX, and provides a reliable platform for in silico hypothesis testing or recommendation on novel therapies. These results can support the development of RA translational research in the design of validation experiments and clinical trials, as such we identify GRB2 as a robust potential new target for RA for its ability to control both synovial degeneracy and dysbiosis, and, conversely, warn on the usage of IRAK4-inhibitors recently promoted, as this involves potential adverse effects in the form of impaired innate response to pathogens.

    A numerical study on the effect of side-dump number on fuel droplets sizing and effective mass fraction have been investigated in present paper. The mass of fuel vapor inside the flammability limit is named as the effective mass fraction. In the first step we have considered a side-dump combustor with two dumps and dump angle of 0o (plumb to cylinder) and by increasing the entrance airflow velocity from 20 to 30, 40 and 50 (m/s) respectively, the mean diameter of fuel droplets sizing and effective mass fraction have been studied. After this step, we have changed the number of dumps from two to four and we have repeated last examination again. To fulfill the calculations a modified version of KIVA-3V code which is a transient, three-dimensional, multiphase, multicomponent code for the analysis of chemically reacting flows with sprays, is used.

  10. Macrophages are involved in hexachlorobenzene-induced adverse immune effects

    International Nuclear Information System (INIS)

    Hexachlorobenzene (HCB) is a persistent environmental pollutant that causes adverse immune effects in man and rat. The Brown Norway (BN) rat is very susceptible to HCB-induced immunopathology and oral exposure causes inflammatory skin and lung lesions, splenomegaly, lymph node (LN) enlargement, and increased serum levels of IgE and anti-ssDNA IgM. T cells play an important role but do not account for all adverse effects induced by HCB. Macrophages are probably also important and the relationship between macrophages and T cells was further investigated. To eliminate macrophages clodronate-liposomes were used. Furthermore, a kinetic study was performed to obtain insight in the early phase of the HCB-induced immune response. Also, experiments were performed to detect specific memory T cells. Therefore, an adoptive transfer study was performed. Our results indicate that macrophages are indeed involved in HCB-induced skin lesions, lung eosinophilia, and elevation of IgM against ssDNA. Kinetics showed that both skin and lung lesions appeared early after exposure. Moreover, immune effects could not be adaptively transferred. Thus, both macrophages and T cells are involved in HCB-induced immune effects but HCB exposure does not lead to specific T cell sensitization. Presumably, HCB exposure induces macrophage activation, thereby generating adjuvant signals that polyclonally stimulate T cells. Together, these events may lead to the observed immunopathology in BN rats

    Radiation exposure in space is expected to increase the risk of cancer and other adverse biological effects in astronauts. The types of space radiation of particular concern for astronaut health are protons and heavy ions known as high atomic number and high energy (HZE) particles. Recent studies have indicated that carcinogenesis induced by protons and HZE particles may be modifiable. We have been evaluating the effects of proton and HZE particle radiation in cultured human cells and animals for nearly a decade. Our results indicate that exposure to proton and HZE particle radiation increases oxidative stress, cytotoxicity, cataract development and malignant transformation in in vivo and/or in vitro experimental systems. We have also shown that these adverse biological effects can be prevented, at least partially, by treatment with antioxidants and some dietary supplements that are readily available and have favorable safety profiles. Some of the antioxidants and dietary supplements are effective in preventing radiation induced malignant transformation in vitro even when applied several days after the radiation exposure. Our recent progress is reviewed and discussed in the context of the relevant literature.

    2014-06-01

    Treatment of paracetamol intoxication consists of administration of N-acetylcysteine, preferably shortly after paracetamol ingestion. In most countries, the decision to treat patients with N-acetylcysteine depends on the paracetamol plasma concentration. In the literature, different arguments are given regarding when to treat paracetamol overdose. Some authors do not recommend treatment with N-acetylcysteine at low paracetamol plasma concentrations since unnecessary adverse effects may be induced. But no treatment with N-acetylcysteine at higher paracetamol plasma concentrations may lead to unnecessary severe morbidity and mortality. In this review, we provide an overview on the severity and prevalence of adverse side effects after N-acetylcysteine administration and the consequences these side effects may have for the treatment of paracetamol intoxication. The final conclusion is to continue using the guidelines of the Dutch National Poisons Information Centre for N-acetylcysteine administration in paracetamol intoxication. PMID:24930458

    BACKGROUND: Bevacizumab is humanized monoclonal antibody inhibiting angiogenesis and the only FDA approved treatment for recurrent glioblastoma. The aim of this study was to look at the occurrence of various adverse effects associated with use of bevacizumab in recurrent glioblastoma. METHODS: In this retrospective chart review, we studied 280 patients with recurrent glioblastoma treated with Bevacizumab between 2005-2011 to characterize the known adverse effects of bevacizumab including hypertension, grade 3-4 myelosuppression, wound healing complications, thrombo-embolic events, stroke, hemorrhage and gastrointestinal complications. RESULTS: The study population included 168 males and 112 females. The median age was 53.5 years(range 8.1-81.3). TREATMENT: Bevacizumab only(58), Bevacizumab + CPT(11), Bevacizumab + TMZ(32) or Bevacizumab + Other(34). Patients were treated at recurrence(1st = 96; 2nd = 126, 3rd = 58). Hypertension was the most common adverse effect occurring in 131(49%). The median duration from treatment start to development was 82 days (Range 7-1143). However, only 33(25%) were started on antihypertensive medication. Grade 3-4 Myelosuppression occurred in 52(19%)causing treatment discontinuation in 8. Thrombo-embolic events were reported in 5%(15) patients including DVT(9), PE(2), Central venous thrombosis(1) and Stroke(3). Thirty-six patients (13%) were on anti-coagulant medication at bevacizumab initiation. Median time to a thromboembolic complication was 113 days (Range 8-1145). Wound healing complications were noted in 7(3%) patients, 3 craniotomy dehiscence and 4 at soft tissue sites. Five patients (2%) developed GI complications, including perforations(3), pancreatitis(1), and diverticulitis(1). Median time to development was 92 days(Range 10-651). There was a high rate 46%(129) of grade 3-4 lymphocytopenia; median time to develop lymphocytopenia was 50 days(Range = 3-564). CONCLUSION: The range of toxicities was similar to other reports

    Full Text Available Obesity and overeating are among the most prevalent health concerns worldwide and individuals are increasingly using performance and image-enhancing drugs (PIEDs as an easy and fast way to control their weight. Among these, herbal weight-loss products (HWLPs often attract users due to their health claims, assumed safety, easy availability, affordable price, extensive marketing, and the perceived lack of need for professional oversight. Reports suggest that certain HWLPs may lead to onset or exacerbation of psychiatric disturbances. Here we review the available evidence on psychiatric adverse effects of HWLPs due to their intrinsic toxicity and potential for interaction with psychiatric medications.

  17. Systemic and Nonrenal Adverse Effects Occurring in Renal Transplant Patients Treated with mTOR Inhibitors

    2013-01-01

    Full Text Available The mammalian target of rapamycin inhibitors (mTOR-I, sirolimus and everolimus, are immunosuppressive drugs largely used in renal transplantation. The main mechanism of action of these drugs is the inhibition of the mammalian target of rapamycin (mTOR, a regulatory protein kinase involved in lymphocyte proliferation. Additionally, the inhibition of the crosstalk among mTORC1, mTORC2, and PI3K confers the antineoplastic activities of these drugs. Because of their specific pharmacological characteristics and their relative lack of nephrotoxicity, these inhibitors are valid option to calcineurine inhibitors (CNIs for maintenance immunosuppression in renal transplant recipients with chronic allograft nephropathy. However, as other immunosuppressive drugs, mTOR-I may induce the development of several adverse effects that need to be early recognized and treated to avoid severe illness in renal transplant patients. In particular, mTOR-I may induce systemic nonnephrological side effects including pulmonary toxicity, hematological disorders, dysmetabolism, lymphedema, stomatitis, cutaneous adverse effects, and fertility/gonadic toxicity. Although most of the adverse effects are dose related, it is extremely important for clinicians to early recognize them in order to reduce dosage or discontinue mTOR-I treatment avoiding the onset and development of severe clinical complications.

    Full Text Available Due to the important role of thyroid disorders on reproductive health of the women of childbearing age, pregnancy outcome, fetal health, and neurodevelopment of the infant, providing comprehensive assessment of the treatments used for preventing hyperthyroidism and hypothyroidism seems to be essential. Therefore, evaluating the efficacy of different treatments of the thyroid disorders would be beneficial in better managing and controlling the disease during pregnancy. Hypothyroidism (a deficiency of thyroid hormone is a common thyroid disorder, which might increase the incidence rate of miscarriage, pre-eclampsia, placental abruption, and preterm delivery. Hyperthyroidism, which is not a common disorder during the pregnancy not only leads to similar adverse effects as hypothyroidism but also can result in stillbirth and intrauterine growth restriction. Levothyroxine is the preferred treatment of hypothyroidism and the only drug therapy recommended for treating hyperthyroidism during pregnancy. In this study, we aimed to briefly review the adverse effects of hyperthyroidism and hypothyroidism during pregnancy and review the effects of recent suggested treatments for controlling thyroid disorders on pregnancy outcomes.

  4. Are peripheral opioid antagonists the solution to opioid side effects?

    LENUS (Irish Health Repository)

    Bates, John J

    2012-02-03

    Opioid medication is the mainstay of therapy for severe acute and chronic pain. Unfortunately, the side effects of these medications can affect patient comfort and safety, thus limiting their proven therapeutic potential. Whereas the main analgesic effects of opioids are centrally mediated, many of the common side effects are mediated via peripheral receptors. Novel peripheral opioid antagonists have been recently introduced that can block the peripheral actions of opioids without affecting centrally mediated analgesia. We review the clinical and experimental evidence of their efficacy in ameliorating opioid side effects and consider what further information might be useful in defining their role. IMPLICATIONS: The major analgesic effects of opioid medication are mediated within the brain and spinal cord. Many of the side effects of opioids are caused by activation of receptors outside these areas. Recently developed peripherally restricted opioid antagonists have the ability to block many opioid side effects without affecting analgesia.

    The athletic performance supplement industry is a multibillion-dollar business and one popular category claims to increase nitric oxide (NO) production. We report three patients presenting to the emergency department with adverse effects. A 33-year-old man presented with palpitations, dizziness, vomiting, and syncope, after the use of NO(2) platinum. His examination and electrocardiogram (ECG) were normal. The dizziness persisted, requiring admission overnight. A 21-year-old man with palpitations and near syncope had used a "nitric oxide" supplement. He was tachycardic to 115 bpm with otherwise normal examination. Laboratory values including methemoglobin, and ECG were unremarkable. He was treated with 1 L of saline with no change in heart rate. He was admitted for observation. A 24-year-old man presented after taking NO-Xplode with palpitations and a headache. His examination, laboratory values, and ECG were normal. He was discharged. The purported active ingredient in these products is arginine alpha-ketoglutarate (AAKG), which is claimed to increase NO production by supplying the precursor L-arginine. The symptoms could be due to vasodilation from increased levels of NO, though other etiologies cannot be excluded. AAKG containing supplements may be associated with adverse effects requiring hospital admission. PMID:19755457

    2014-09-01

    Atypical antipsychotic drugs are not all alike with respect to their pharmacologies, therapeutic uses, and side eff ects, although many clinicians lump them together and do not distinguish among them. Risk assessment for the potential use of a drug, such as aripiprazole (Abilify), should not focus on any particular adverse effect, but rather should consider risk assessment in a broader context. Specifically, what are the alternatives, and what are their inherent risk profiles? What is the risk of no treatment? Side eff ects commonly associated with a particular drug or class of drugs can also occur with other drugs. For any drug prescribed for any reason, prescribers should document discussion about common and potentially serious adverse effects, as well as document clinical monitoring. Alternative treatments and their inherent risks, along with the risks of not taking medication for a particular condition, should also be discussed with patients and documented. PMID:25346958

    Botox® injections are taking a consistently increasing place in urology. Intracremasteric injections, particularly, have been applied for cryptorchidism and painful testicular spasms. Studies outlining their safety for this use are, however, scanty. Thus, the present study aimed at evaluating possible testicular toxicity of Botox® injections and their effect on male fertility. Mature rats were given intracremasteric Botox® injections (10, 20 and 40 U/kg) three times in a two-week interval. Changes in body and testes weights were examined and gonadosomatic index compared to control group. Semen quality, sperm parameters, fructose, protein, cholesterol and triglycerides contents were assessed. Effects on normal testicular function were investigated by measuring testosterone levels and changes in enzyme activities (lactate dehydrogenase-X and acid phosphatase). To draw a complete picture, changes in oxidative and inflammatory states were examined, in addition to the extent of connective tissue deposition between seminiferous tubules. In an attempt to have more accurate information about possible spermatotoxic effects of Botox®, flowcytometric analysis and histopathological examination were carried out. Botox®-injected rats showed altered testicular physiology and function. Seminiferous tubules were separated by dense fibers, especially with the highest dose. Flowcytometric analysis showed a decrease in mature sperms and histopathology confirmed the findings. The oxidative state was, however, comparable to control group. This study is the first to show that intracremasteric injections of Botox® induce adverse testicular effects evidenced by inhibited spermatogenesis and initiation of histopathological changes. In conclusion, decreased fertility may be a serious problem Botox® injections could cause. - Highlights: • Botox® injections are the trend nowadays, for both medical and non-medical uses. • They were recently suggested for cryptorchidism and

    Full Text Available BACKGROUND Acquired Immunodeficiency Syndrome, a disease of the human immune system caused by the Human Immunodeficiency Virus (HIV is a major health problem in many parts of the world. The prognosis was dramatically altered with the introduction of antiretroviral drugs in 1987 and Highly Active Antiretroviral Therapy (HAART in 1996. Despite the absence of a cure, the natural history of the disease was radically changed since then. This study aimed at documenting and analysing the adverse effect profile of Tenofovir Disoproxil Fumarate-based Antiretroviral Therapy (ART in HIV positive patients attending Antiretroviral Therapy Centre, Government Medical College, Thrissur. METHODOLOGY HIV positive patients on Tenofovir Disoproxil Fumarate-based antiretroviral treatment attending Antiretroviral Therapy Centre, Government Medical College, Thrissur, were enrolled in the prospective cohort study conducted over 18 months from Jan 2013- June 2014. The patients were followed up for 12 months pattern of adverse drug reactions. RESULTS A total of 178 Adverse Drug Reactions (ADRs were identified, out of which 86 (48.31% were in male and 92 (51.68% were in female patients. Out of 178 suspected ADRs, 172 (96.6% ADRs were reported from outpatient departments. Six patients (3.3% required hospital admission. The most commonly identified adverse drug reactions were nausea and vomiting in 54 (30.3% patients, headache and fatigue in 30 (16.85%, heartburn and diarrhoea in 17 (9.5% cases, lab abnormalities like dyslipidaemia in 12 (6.74%, hyperphosphatemia in 10 (5.6%, hypocalcemia in 5 (2.85% patients. Out of 178 ADRs, 4 (2.2% were of acute renal failure seen. One among the four died even after discontinuation of the drug, 2 were changed to non-Tenofovir based regimen who improved later within 2 months. CONCLUSION In this study of Tenofovir based regimen, the side effects which necessitated regimen change were very few. Majority of the side effects were GI related

    Guo, Xiaoqing; Mei, Nan

    2016-04-01

    The Aloe plant is employed as a dietary supplement in a variety of foods and as an ingredient in cosmetic products. The widespread human exposure and its potential toxic and carcinogenic activities raise safety concerns. Chemical analysis reveals that the Aloe plant contains various polysaccharides and phenolic chemicals, notably anthraquinones. Ingestion of Aloe preparations is associated with diarrhea, hypokalemia, pseudomelanosis coli, kidney failure, as well as phototoxicity and hypersensitive reactions. Recently, Aloe vera whole leaf extract showed clear evidence of carcinogenic activity in rats, and was classified by the International Agency for Research on Cancer as a possible human carcinogen (Group 2B). This review presents updated information on the toxicological effects, including the cytotoxicity, genotoxicity, carcinogenicity, and adverse clinical effects of Aloe vera whole leaf extract, gel, and latex.

    Full Text Available Introduction. Chronic hepatitis C currently represents a global health problem, which is expected to be reduced by pegylated-interferon and ribavirin therapy. Material and Methods. We examined 88 patients with chronic hepatitis C, divided into three groups according to their comorbidity: the patients without comorbidity were in group I, group II included the patients on dialysis, and group III included the patients with hemophilia. Results. A significant difference was found in the percentage of achieved sustained virological response between the patients on dialysis and other patients, p<0.05. Having analyzed the therapy adverse effects, we observed a significantly higher decrease of erythrocytes count, hemoglobin and hematocrit levels in dialysis patients compared to others (p<0.01. The patients on hemodialysis predominantly had anemia and leukopenia, while thrombocytopenia was equally present in all groups. The dominant clinical side effect was flu-like syndrome, present in more than a half of patients. Discussion. The therapy positive effect is usually accompanied with adverse effects. The lowest therapeutic response was recorded in group II, due to the virus genotype 1. A significant decrease in hematological parameters was determined in all patients. The most common clinical adverse effect was flu-like syndrome, later manifestations included: weight loss, alopecia, insomnia and irritability. Side effects like psychosis, thyroid gland dysfunction or psoriasis were not recorded. Conclusion. A significant decrease in the value of all these hematological parameters was found in all groups of patients. Clinical side effects were present in 60% of patients. Side effects did not lead to discontinuation of therapy, but only to modification of drug doses.

  17. Does cannabidiol protect against adverse psychological effects of THC?

    Full Text Available The recreational use of cannabis can have persistent adverse effects on mental health. Delta-9-tetrahydrocannabinol (THC is the main psychoactive constituent of cannabis, and most, if not all, of the effects associated with the use of cannabis are caused by THC. Recent studies have suggested a possible protective effect of another cannabinoid, cannabidiol (CBD. A literature search was performed in the bibliographic databases PubMed, PsycINFO and Web of Science using the keyword ‘cannabidiol.’ After removing duplicate entries, 1295 unique titles remained. Based on the titles and abstracts, an initial selection was made. The reference lists of the publications identified in this manner were examined for additional references. Cannabis is not a safe drug. Depending on how often someone uses, the age of onset, the potency of the cannabis that is used and someone's individual sensitivity, the recreational use of cannabis may cause permanent psychological disorders. Most recreational users will never be faced with such persistent mental illness, but in some individuals cannabis use leads to undesirable effects: cognitive impairment, anxiety, paranoia and increased risks of developing chronic psychosis or drug addiction. Studies examining the protective effects of CBD have shown that CBD can counteract the negative effects of THC. However, the question remains of how the laboratory results translate to the types of cannabis that are encountered by real-world recreational users.

    2008-09-01

    Depending on etiology, the esthetic treatment of dyschromia may involve vital tooth- bleaching techniques. Hydrogen peroxide is the active molecule used for such procedures; however, its action mechanism is not clearly understood. Moreover, a variety of contradictory studies make difficult the evaluation of the safety of bleaching techniques. The purpose of this article is therefore to review the available literature (1) to describe the physicochemical properties of hydrogen peroxide and (2) to assess the safety of its use as a vital tooth-bleaching agent. Indeed, based on hydrogen peroxide's capacity to generate free radicals that diffuse throughout the dental hard tissues, concerns have been addressed regarding the adverse effects that bleaching products can induce on the enamel and dentin structures, pulp, and bonding to a composite resin system. Moreover, during self-application of home bleaching products, hydrogen peroxide is released into the oral cavity and ingested. Some questions have therefore arisen concerning its toxicity and its possible carcinogenicity. PMID:19107251

    2014-07-01

    Full Text Available Antiretroviral therapy has been associated with side effects, either from the drug itself or in conjunction with the effects of human immunodeficiency virus infection. Here, we evaluated the side effects of the protease inhibitor (PI indinavir in hamsters consuming a normal or high-fat diet. Indinavir treatment increased the hamster death rate and resulted in an increase in triglyceride, cholesterol and glucose serum levels and a reduction in anti-oxLDL auto-antibodies. The treatment led to histopathological alterations of the kidney and the heart. These results suggest that hamsters are an interesting model for the study of the side effects of antiretroviral drugs, such as PIs.

  1. Adverse effects of beta-agonists: are they clinically relevant?

    Science.gov (United States)

    Abramson, Michael J; Walters, Julia; Walters, E Haydn

    2003-01-01

    Inhaled beta(2)-adrenoceptor agonists (beta(2)-agonists) are the most commonly used asthma medications in many Western countries. Minor adverse effects such as palpitations, tremor, headache and metabolic effects are predictable and dose related. Time series studies suggested an association between the relatively nonselective beta-agonist fenoterol and asthma deaths. Three case-control studies confirmed that among patients prescribed fenoterol, the risk of death was significantly elevated even after controlling for the severity of asthma. The Saskatchewan study not only found an increased risk of death among patients dispensed fenoterol, but also suggested this might be a class effect of beta(2)-agonists. However, in subsequent studies, the long-acting beta(2)-agonist salmeterol was not associated with increased asthma mortality. In a case-control study blood albuterol (salbutamol) concentrations were found to be 2.5 times higher among patients who died of asthma compared with controls. It is speculated that such toxic concentrations could cause tachyarrhythmias under conditions of hypoxia and hypokalemia. The risk of asthma exacerbations and near-fatal attacks may also be increased among patients dispensed fenoterol, but this association may be largely due to confounding by severity. Although salmeterol does not appear to increase the risk of near-fatal attacks, there is a consistent association with the use of nebulized beta(2)-agonists. Nebulized and oral beta(2)-agonists are also associated with an increased risk of cardiovascular death, ischemic heart disease and cardiac failure. Caution should be exercised when first prescribing a beta-agonist for patients with cardiovascular disease. A potential mechanism for adverse effects with regular use of beta(2)-agonists is tachyphylaxis. Tachyphylaxis to the bronchodilator effects of long-acting beta(2)-agonists can occur, but has been consistently demonstrated only for formoterol (eformoterol) a full agonist, rather

    Full Text Available Development of dental materials has had a great impact on the modern dentistry. The materials ranging from polymers to metals have different applications in dentistry. Besides their important role in healing or improving the function of oral tissues, the materials may show side effects which may, in some cases, lead to severe lesions. In this review the side effects have been summarized considering a new classification for dental materials according to the duration of their applications as temporary or permanent materials. The side effects of the materials are then discussed based on clinical and cellular views.

    Side airbag systems were first introduced into vehicles around 1995 to help protect occupants from injury in side impact crashes. International studies have shown that side airbags are effective in reducing the risk of death and injury, however, serious injuries can still occur even when side airbags deploy. The objective of this study was to use detailed injury information from insurance injury compensation claims data linked to Police reported crash data to determine the effectiveness of side airbags in reducing the risk of death or injury for occupants involved in side impact crashes in Victoria, Australia based on the specific body regions that side airbag systems are designed to protect. It was found that head and torso-protecting dual airbag systems designed to protect the head, neck, face, chest and abdomen are highly effective in reducing driver death or injury due to near side crashes. They were associated with a statistically significant reduction of 41.1% (25.9%, 53.2%) in the odds of death or injury across all body regions; and a 48.0% (28.0%, 62.4%) reduction in the odds of death or injury to the head, neck, face, chest and abdomen. The study did not find any evidence that torso-protecting airbags alone are effective in reducing death or injury. Analysis results indicate that head and torso-protecting side airbag systems in vehicles are a highly effective technology for reducing the risk of death or injury to vehicle occupants in near side crashes. The magnitude of the injury reduction benefits estimated indicate that fitment of this technology to all vehicles should be a high priority and will yield significant savings in overall road trauma.

  6. Combined radiotherapy and chemotherapy: pulmonary side effects

    International Nuclear Information System (INIS)

    Systemic chemotherapy and lung irradiation have very similar effects on lung tissue. Several mechanisms are involved, mainly: - cytotoxic effects on lung cells (type II pneumocytes, capillary endothelial cells, and connective tissue); - enhancement of infection; - hypersensitivity and auto-immune phenomena. Acute pneumonitis of chronic lung sclerosis develops which may or may not be compatible with life, depending on the lung volume involved and the clinical course. These effects are dose dependent for radiotherapy, and for most of the chemotherapeutic drugs. In some cases however, the dose-effect relationship is not clear, especially with some drugs such as methotrexate, and sometimes with radiotherapy even when it can be assumed that there is no mistake in dose calculation. It must be stressed that we still lack basic knowledge on the pharmacokinetics and actual concentration of drugs in lung tissue. Additive or supra-additive effects are likely when chemotherapy is combined with lung irradiation, but current relevant data does not allow any firm conclusions to be drawn on the quantitative changes resulting from the association. Prevention of lung complications is however possible if the tolerance doses and the optimal distribution of each agent with time are respected. Combined lung irradiation and bleomycin administration must be avoided

  7. Parenteral Lipid Tolerance and Adverse Effects: Fat Chance for Trouble?

    Science.gov (United States)

    Wanten, Geert J A

    2015-09-01

    Lipid emulsions (LEs) are indispensable sources of fuel calories and (essential) fatty acids (FAs) in modern parenteral nutrition formulations. The use of LE, however, also remains associated with the development of adverse effects. Intolerance for LE mostly becomes apparent upon the development of patient complaints or disturbed blood function tests, mainly of the liver. These issues may be associated with the composition, stability, or the infusion rate of the emulsion. Also, altered balances of (anti)oxidants or the presence or absence of protective or toxic bioactive agents such as phytosterols and tocopherol in LE may lead to complications, especially in already vulnerable patients with an inflammatory condition. While the oldest available LEs are based on pure soybean oil (SO-LE), rich in the proinflammatory ω-6 polyunsaturated fatty acid linoleic acid, more recent next-generation LEs where alternative FA sources such as olive and fish oil (partially) replace soybean oil to lower the content of linoleic acid seem safe and effective. Especially LEs containing fish oil (FO-LE) have less proinflammatory characteristics that promise to convey beneficial effects on immune system and organ functions, although much of the available evidence awaits more robust clinical validation.

    Full Text Available Aim of the study: To report adverse events registered in our population affected by JIA and treated with anti-TNFa blockers. Methods: Ninety-five patients were enrolled to be treated with Etanercept, median age 14 years (range 4-34; median duration of therapy 12 months (range1-40. 19 patients were als treated with MTX (median dose 12.5 mg/week. Fifty-six patients were enrolled to be treated with Infliximab associated with MTX (median dose of MTX 8.8mg/week, median age 23.2 years (range 7.8-34.9; median duration of therapy 20.1 months (range 1.4-60.4. All adverse events were divided in definitely, probably and possibly related to the biologic agent. Results: Side effects definitely related to Infliximab were the reactions to infusions and the Anti-dsDNA positivity. Side effects definitely related to Etanercept were severe headache and thrombocytopenia. Side effects probably correlated to both the biological agents were behavioural modifications and pain amplification syndrome. Probably correlated to the treatment with Etanercept was the onset of Crohn’s disease in 3 patients. Possibly correlated to the biological agents were the new onset or flare-up of Chronic Iridocyclitis and single cases of thyroideal cancer, hypoglossal nerve paralysis and a severe Cytomegalovirus pulmonary infection. No case of tuberculosis infection was registered during this study. Conclusions: Treatment with a TNFa antagonist seems to be associated with various adverse events. Some of them, like onset of Crohn’s disease, behavioural modifications are unusual and others, like pain amplification syndrome were never described before. Children and young adults affected by JIA should be monitored very carefully so as to limit as much as possible the risk of serious side effects on anti-TNFa therapy.

    The in vivo repeated dose toxicity (RDT) test is intended to provide information on the possible risk caused by repeated exposure to a substance over a limited period of time. The measure of the RDT is the no observed adverse effect level (NOAEL) that is the dose at which no effects are observed, i.e., this endpoint indicates the safety level for a substance. The need to replace in vivo tests, as required by some European Regulations (registration, evaluation authorization and restriction of chemicals) is leading to the searching for reliable alternative methods such as quantitative structure-activity relationships (QSAR). Considering the complexity of the RDT endpoint, for which data quality is limited and depends anyway on the study design, the development of QSAR for this endpoint is an attractive task. Starting from a dataset of 140 organic compounds with NOAEL values related to oral short term toxicity in rats, we developed a QSAR model based on optimal descriptors calculated with simplified molecular input-line entry systems and the graph of atomic orbitals by the Monte Carlo method, using CORAL software. Three different splits into the training, calibration, and validation sets are studied. The mechanistic interpretation of these models in terms of molecular fragment with positive or negative contributions to the endpoint is discussed. The probabilistic definition for the domain of applicability is suggested. PMID:25850638

    Aesthetic medicine has become increasingly popular in the last two decades. The same trend has occurred in dermatology. Aesthetic dermatology prefers minimally invasive procedures. Nevertheless, even these procedures are not free of possible adverse effects. The spectrum of possible adverse effects, their management and prevention are discussed for four popular procedures in aesthetic dermatology, i.e. chemical peels, mesotherapy, botulinum toxin, and dermal fillers. Aesthetic procedures should only be performed by well-educated, well-trained medical doctors with an excellent medical background, never by lay persons. PMID:23430168

    2012-12-21

    Drug side-effects, or adverse drug reactions, have become a major public health concern and remain one of the main causes of drug failure and of drug withdrawal once they have reached the market. Therefore, the identification of potential severe side-effects is a challenging issue. In this paper, we develop a new method to predict potential side-effect profiles of drug candidate molecules based on their chemical structures and target protein information on a large scale. We propose several extensions of kernel regression model for multiple responses to deal with heterogeneous data sources. The originality lies in the integration of the chemical space of drug chemical structures and the biological space of drug target proteins in a unified framework. As a result, we demonstrate the usefulness of the proposed method on the simultaneous prediction of 969 side-effects for approved drugs from their chemical substructure and target protein profiles and show that the prediction accuracy consistently improves owing to the proposed regression model and integration of chemical and biological information. We also conduct a comprehensive side-effect prediction for uncharacterized drug molecules stored in DrugBank and confirm interesting predictions using independent information sources. The proposed method is expected to be useful at many stages of the drug development process. PMID:23157436

  19. Side effects of adjuvant radiotherapy in men with testicular seminoma stage I

    International Nuclear Information System (INIS)

    In this study we followed up the side effects of adjuvant radiotherapy in patients with testicular seminoma stage I over a period from 13 to 84 months (median 28 months). The most frequent side effects during radiotherapy were gastrointestinal (nausea/vomiting), psychological, cognitive, and minor sexual problems. The reported side effects were treated by antiemetics and anxiolytics. After radiotherapy, the side effects persisted in 6 % of patients, but only a few of them required additional treatment. Healthy children were born to 76 % of patients in the 18 to 39 years age group. This study shows that adjuvant radiotherapy of the para-aortic lymph nodes with the total dosage of 24 Gy in 16 daily fractions administered to testicular seminoma patients causes acceptable side effects, does not adversely affect quality of life and fertility, if the approach to treatment is individual and family consulting is provided. This makes adjuvant radiotherapy of the para-aortic lymph nodes an acceptable treatment for testicular seminoma stage I patients. (authors)

    1980-11-22

    Knowledge and attitudes of adolescent females regarding the side effects of oral contraceptives were investigated. The data source was a large study of sexual and contraceptive attitudes and experience. The questionnaire responses of 486 single females attending 10 birth control and pregnancy counseling centers in Ontario, Canada were examined. The age range of the subjects was from 13-20; 71% were attending school and 69% were living at home. They were attending the centers in order to obtain contraceptives (55%), to renew OC prescriptions (20%), or to receive pregnancy counseling (25%). 29% of the subjects had used OCs before coming to the clinic, but 91% planned to use OC after their clinic visit. 8% were planning to use an IUD; 1% were planning to use a diaphragm; and less than 1% were planning to have their boyfriend use condoms. 85% of the subjects indicated that they had heard abut side effcts of OCs with weight gain as the best known side effect. Other side effects familiar to many included nausea, circulatory disorders, headaches, emotional changes, menstrual problems and cancer. About 1/2 of the subjects had learned about these side effects from the mass media or female friends, 25% from a school sex education class, 15% from their mothers, and 3% from a physician. Despite knowledge regarding side effects, most of the subjects had positive attitudes toward OCs with 59% believing that the advnatages outweighed any disadvantages. PMID:7448666

  2. Second-Generation Antipsychotics and Extrapyramidal Adverse Effects

    Antipsychotic-induced extrapyramidal adverse effects are well recognized in the context of first-generation antipsychotic drugs. However, the introduction of second-generation antipsychotics, with atypical mechanism of action, especially lower dopamine receptors affinity, was met with great expectations among clinicians regarding their potentially lower propensity to cause extrapyramidal syndrome. This review gives a brief summary of the recent literature relevant to second-generation antipsychotics and extrapyramidal syndrome. Numerous studies have examined the incidence and severity of extrapyramidal syndrome with first- and second-generation antipsychotics. The majority of these studies clearly indicate that extrapyramidal syndrome does occur with second-generation agents, though in lower rates in comparison with first generation. Risk factors are the choice of a particular second-generation agent (with clozapine carrying the lowest risk and risperidone the highest), high doses, history of previous extrapyramidal symptoms, and comorbidity. Also, in comparative studies, the choice of a first-generation comparator significantly influences the results. Extrapyramidal syndrome remains clinically important even in the era of second-generation antipsychotics. The incidence and severity of extrapyramidal syndrome differ amongst these antipsychotics, but the fact is that these drugs have not lived up to the expectation regarding their tolerability.

    The present study was undertaken to evaluate the oxidative damage, biochemical and histopathological alterations in sucking rats whose mothers were exposed to the insecticide chlorpyrifos (CPF). Dams were administered CPF, via oral route. Doses equalled 0.01 mg kg(-1) body weight (b.wt.; acceptable daily intake, ADI), 1.00 mg kg(-1) b.wt. (no observed adverse effects level, NOAEL) and 1.35 mg kg(-1) b.wt. (1/100 lethal dose [LD(50)]) from postnatal day 1 until day 20 after delivery. At two high doses of CPF, the body weight gain and relative liver and kidney weight of suckling pups were significantly decreased. Exposure of the mothers to CPF caused increase in lipid peroxidation (LPO) and decrease in superoxide dismutase (SOD) and glutathione-s-transferase (GST) in lactating pups. CPF altered the level of the marker parameters related to the liver and kidneys. Consistent histological changes were found in the liver and kidneys of the subjected pups, especially at the higher doses. The results suggested that the transfer of CPF intoxication through the mother's milk has resulted in oxidative stress and biochemical and histopathological alterations in the suckling pups. The data of this study may be considered as a contribution to the problem of lactational transfer of the relatively less persistent OP pesticides, such as CPF. PMID:20028704

    Full Text Available Abstract Background Mammary tumors are among the most frequent neoplasms in female dogs, but the strategies employed in animal treatment are limited. In human medicine, hormone manipulation is used in cancer therapy. Tamoxifen citrate is a selective inhibitor of oestrogen receptors and exerts a potent anti-oestrogen effect on the mammary gland. The aim of this study was to evaluate the adverse effects when exposing healthy female dogs to tamoxifen. Methods Tamoxifen was administered for 120 days at a dose of 0.5 or 0.8 mg/kg/day to either intact or spayed female dogs. The effects were assessed through clinical examination, haematology, serum biochemistry, ophthalmology and bone marrow aspirate examination. Ovariohysterectomy was performed and the uterus examined by histopathology. Results Vulva oedema and purulent vaginal discharge developed with 10 days of tamoxifen exposure in all groups. Pyometra was diagnosed after around 90 days of exposure in intact females with frequencies increasing during the following 30 days of exposure. Up to 50% of dogs within the groups developed retinitis but none of the dogs had signs of reduced visual acuity. The prevalence of retinitis in each group was similar after 120 days of exposure. Haematological, biochemical and bone marrow changes were not observed. Due to the high risk of developing pyometra after prolonged exposure to tamoxifen, only spayed animals should be given this medication. Conclusions A dose of 0.8 mg tamoxifen/kg body weight/day is recommended when treating tamoxifen-responsive canine mammary tumors. Due to the high risk of developing pyometra, ovariohysterectomy is recommended.

We report herein a case of a 16-year-old Chinese boy with depression who experienced extrapyramidal-like effects, for example, facial spasm, upper limb dystonia, akathisia, and other disturbed behaviors, while being treated with sertraline 200 mg per day. His movement symptoms were significantly alleviated after the discontinuation of sertraline and the administration of scopolamine. This finding indicates that albeit infrequent, sertraline may cause severe extrapyramidal symptoms in adolescent patients, suggesting that clinicians should be alert to the neurological side effects of sertraline in young patients.

  6. Cutaneous adverse effect during concomitant therapy with phenytoin and holoencefalica radiotherapy

    International Nuclear Information System (INIS)

    Introduction: Phenytoin is one of anticonvulsant drugs (AC) which together with the Corticosteroids are used frequently in patients with intracranial tumors either early or metastatic; the association of treatments can cause adverse effects within which are skin reactions called erythema multiforme (EM) syndrome Stevens-Johnson syndrome (SJS) and toxic epidermal necrolysis (TEN) whose incidence is 5 to 10%, with an increased risk are used when the AC associated with treatment with radiotherapy (RT).Case report: A 48 year old woman in whom primitive brain metastases were diagnosed breast cancer, so phenytoin, corticosteroids and performed RT presenting holoencefálica for such treatment maculo-papular skin reaction symmetrical onset zone Radiant treatment extension neck, thorax, abdomen and pelvis, oral mucositis, conjunctivitis and fever, which improved after stopping treatment altogether. Discussion: The clinical picture presented matches the description of the 30 Reported SJS / TEN in the literature with the use of AC and RT cases. The clinical course of the skin reactions in our patient represents the possible combined effect of phenytoin and RT as causative agents and analyzed the occurrence of side effects occurred in the third week of starting treatment with both therapeutic modalities such as what described in these reactions and improved frankly to stop treatment until disappear entirely. Cutaneous adverse reactions may occur as a complication severe in patients treated with RT and phenytoin and both treatments should suspend the first sign of side effects must continue once the patient recovered with AC radiant modifying drug treatment if necessary. There are differences of opinion regarding the prophylactic use of drug therapy in patients with AC intracranial tumors both early and metastatic. The American Academy of Neurology held a consensus in 2000 whose recommendations are non-routine use of AC in patients diagnosed intracerebral tumor that has not

    Although sex differences in several aspects of substance use disorders (SUDs) have been identified, less is known about the importance of possible sex differences in side effects induced by substances of abuse or by medications used to treat SUDs. In the SUD field, the perception of certain subjective effects are actively sought, while all other manifestations might operationally be considered side effects. This article was aimed at reviewing sex differences in side effects induced by alcohol, nicotine, heroin, marijuana and cocaine and by medications approved for alcohol, nicotine and heroin use disorders. A large body of evidence suggests that women are at higher risk of alcohol-induced injury, liver disease, cardiomyopathy, myopathy, brain damages and mortality. The risk of tobacco-induced coronary heart disease, lung disease and health problems is higher for women than for men. Women also experience greater exposure to side effects induced by heroin, marijuana and cocaine. In addition, women appear to be more vulnerable to the side effects induced by medications used to treat SUDs. Patients with SUDs should be advised that the risk of developing health problems may be higher for women than for men after consumption of the same amount of substances of abuse. Doses of medications for SUD women should be adjusted at least according to body weight. The sex differences observed also indicate an urgent need to recruit adequate numbers of female subjects in pre-clinical and clinical studies to improve our knowledge about SUDs in women.

    Calcineurin inhibition with tacrolimus has been used after renal transplantation (RTPL) as rescue therapy for insufficient immunological control or if cyclosporin A (CSA) toxicity occurred. Neurologic side-effects occur but are rare in children, usually presenting as tremor; however, serious complications, e.g. the posterior leukoencephalopathy syndrome are also documented. Twenty children (10 girls) were switched to tacrolimus: 11 (55%) for immunological reasons (n = 9: steroid-resistant rejection; n = 2: recurrent rejections) and nine for CSA side-effects. Tacrolimus was started at a median of 8 wk (range 10 d to 8.7 yr) after RTPL and was continued for a median of 2.5 yr (range 5 wk to 4.6 yr). Renal function significantly improved over a period of 12 months following conversion to tacrolimus (glomerular filtration rate 56 +/- 19 vs. 66 +/- 16 mL/min/1.73 m2; p side-effects were neuropsychological and behavioral symptoms in three children, ranging from anorexia nervosa-like symptoms with weight loss, amenorrhea, depression and school problems to severe insomnia and to aggressive and anxious behavior in one child. Only the latter child was exposed to toxic tacrolimus blood levels. All side-effects were fully reversible after discontinuation of tacrolimus. In conclusion, tacrolimus had a beneficial effect on renal function and was well tolerated in the majority of pediatric patients. However, neuropsychologic and behavioral side-effects are important and maybe underrecognized in children. PMID:12709079

    Increased utilization of iodinated contrast media may be associated with increased incidence of adverse events. The most important side effects include contrast-induced nephropathy, anaphylactoid reaction, thyrotoxicosis, and extravasation. In patients with moderate renal dysfunction, saline hydration and reduction of contrast media volume are recommended. No regime to prevent anaphylactoid reactions has yet proven to be efficient. If subclinical hyperthyroidism has been determined, prophylaxis with sodium perchlorate is advised. Contrast-induced nephropathy is commonly transient and needs to be followed over time. Mild general anaphylactoid reactions may be treated with antihistaminic drugs and corticosteroids. Furthermore the choice of the X-ray contrast media might influence the risk of any adverse effects.

    Side effects in the therapy of malignant melanoma are primarily of importance for radiologists in advanced tumor stages. The available treatment options and their respective side effect profiles have undergone a profound change in recent years after the introduction of modern oncological therapies (e.g. immunotherapy and targeted therapy) with an increasing focus on individual tumor biology and differ significantly from those of classical chemotherapy. The immunotherapeutic agents, in particular ipilimumab, take on a special position because of their specific immune-mediated mechanisms of action and the associated side effects, so-called immune-related adverse events (irAE). The majority of the treatment effects are manifested on the skin (> 50 %) and are generally not detectable by diagnostic radiology. Only a comparatively small proportion of treatment side effects is detectable with diagnostic imaging (15-20 %) but as in the example of therapy-induced colitis with ipilimumab, may be rapidly fatal. In addition to colitis (10-20 %) further therapy side effects apparent in diagnostic imaging are hypophysitis (1.8-17 %), thyroiditis (0.8 %), myositis (1.7 %), fasciitis and sarcoid-like lymph node alterations (6.8 %). To detect radiologically detectable side effects early on and to delineate them especially from tumor progression and (opportunistic) infections, detailed knowledge of the therapeutic methods for melanoma, the mechanisms of action and in particular the sometimes very specific side effects is imperative for radiologists.

    Steroids are important physiological orchestrators of endocrine as well as peripheral and central nervous system functions. One of the key processes for regulation of these molecules lies in their enzymatic processing by a family of 5α-reductase (5α-Rs) isozymes. By catalyzing a key rate-limiting step in steroidogenesis, this family of enzymes exerts a crucial role not only in the physiological control but also in pathological events. Indeed, both 5α-R inhibition and supplementation of 5α-reduced metabolites are currently used or have been proposed as therapeutic strategies for a wide array of pathological conditions. In particular, the potent 5α-R inhibitors finasteride and dutasteride are used in the treatments of benign prostatic hyperplasia (BPH), as well as in male pattern hair loss (MPHL) known as androgenetic alopecia (AGA). Recent preclinical and clinical findings indicate that 5α-R inhibitors evoke not only beneficial, but also adverse effects. Future studies should investigate the biochemical and physiological mechanisms that underlie the persistence of the adverse sexual side effects to determine why a subset of patients is afflicted with such persistence or irreversible adverse effects. Also a better focus of clinical research is urgently needed to better define those subjects who are likely to be adversely affected by such agents. Furthermore, research on the non-sexual adverse effects such as diabetes, psychosis, depression, and cognitive function are needed to better understand the broad spectrum of the effects these drugs may elicit during their use in treatment of AGA or BPH. In this review, we will summarize the state of art on this topic, overview the key unresolved questions that have emerged on the pharmacological targeting of these enzymes and their products, and highlight the need for further studies to ascertain the severity and duration of the adverse effects of 5α-R inhibitors, as well as their biological underpinnings.

    Purpose: To evaluate side effects of hypofractionated stereotactic photon radiotherapy for patients with choroidal melanoma. Patients and Methods: Two hundred and twelve patients with choroidal melanoma unsuitable for ruthenium-106 brachytherapy or local resection were treated stereotactically at the Medical University of Vienna between 1997 and 2007 with a Linac with 6-MV photon beams in five fractions with 10, 12, or 14 Gy per fraction. Examinations for radiogenic side effects were performed at baseline and every 3 months in the first 2 years, then every 6 months until 5 years and then once a year thereafter until 10 years after radiotherapy. Adverse side effects were assessed using slit-lamp examination, funduscopy, gonioscopy, tonometry, and, if necessary, fundus photography and fluorescein angiography. Evaluations of incidence of side effects are based on an actuarial analysis. Results: One hundred and eighty-nine (89.2%) and 168 (79.2%) of the tumors were within 3 mm of the macula and the optic disc, respectively. The five most common radiotherapy side effects were retinopathy and optic neuropathy (114 cases and 107 cases, respectively), cataract development (87 cases), neovascular glaucoma (46 cases), and corneal epithelium defects (41 cases). In total, 33.6%, 38.5%, 51.2%, 75.5%, and 77.6% of the patients were free of any radiation retinopathy, optic neuropathy, cataract, neovascular glaucoma, or corneal epithelium defects 5 years after radiotherapy, respectively. Conclusion: In centrally located choroidal melanoma hypofractionated stereotactic photon radiotherapy shows a low to moderate rate of adverse long-term side effects comparable with those after proton beam radiotherapy. Future fractionation schemes should seek to further reduce adverse side effects rate while maintaining excellent local tumor control.

    Dizziness is a well-known side effect of a wide range of drugs. However, the side effects reported in the summary of product characteristics are not exclusively based on placebo-controlled trials. Based on a systematic review of the literature including randomised placebo-controlled clinical trials, antihypertensive combination drugs, methylphenidate, high doses of tramadol and serotonin-norepinephrine reuptake inhibitors were associated with an increased risk of dizziness. Antihypertensive monotherapy and selective serotonin reuptake inhibitors were generally not associated with an increased risk of dizziness when compared with placebo. PMID:24629236

    Sexual side effects of finasteride seem to be redoubtable, being encountered not only during therapy but also after treatment cessation. Consequently, any possible clinical/paraclinical elements that might predict these adverse effects would be useful in the selection of a therapeutic strategy for male androgenic alopecia. Previous published studies show that some compounds that interfere with sexual hormones can decrease sexual activation and response, according to hand preference (as reported for finasteride and tamoxifen) and according to sexual orientation (as noted for bicalutamide). Our preliminary published data and the arguments presented here suggest that these two individual parameters might be used by dermatologists in the therapeutic approach of male androgenic alopecia, so as to alert specific subsets of men, prior to treatment, of the potential increased risk for developing adverse effects to finasteride.

    2014-10-01

    In up to 75% of cases, advanced breast cancer patients eventually develop bone metastases with often debilitating skeletal-related events (SREs). Osteoclast inhibitors are commonly used as therapeutic mainstay with clinical studies showing superiority of denosumab over bisphosphonates (e.g., zoledronate) for the prevention of SREs. The present review discusses the adverse event profile of these agents, and addresses the prevention and management of untoward side effects. Adverse events associated with osteoclast inhibitors comprise osteonecrosis of the jaw and hypocalcemia. Hypocalcemia is more common with denosumab, particularly in severe renal dysfunction. During therapy, the appropriate prevention of these adverse events includes close attention to dental health, avoidance of invasive dental procedures, supplementation with calcium and vitamin D unless patients are hypercalcemic, and regular monitoring of relevant serum values. Relating to the risk of nephrotoxicity, bisphosphonates but not denosumab have been incriminated. Therefore, serum creatinine levels should be checked prior to each dose of zoledronate, and in severe renal dysfunction (creatinine clearance < 30 ml/min) zoledronate is contraindicated anyway. Acute-phase reactions are particularly linked to bisphosphonates. Consequently, if these adverse events predominate, switching to denosumab is recommended. PMID:25759613

    Objectives. I-131 therapy for differentiated thyroid cancer (DTC) could induce adverse effects. The purpose of this study was to report and analyze symptoms after I-131 treatment within the hospitalization and present relevant medical intervention. Methods. I-131 doses ranging from 3.7 to 9.25 GBq (100-250 mCi) were administrated for thyroid remnant ablation or treating DTC metastases. 117 patients with DTC for I-131 therapy were monitored through the video and intercommunicating with standardized questionnaire at different time points after I-131 oral administration. Adverse effects were recorded and relevant clinical factors were analyzed. Results. Among all the 117 patients, 55 cases complained of neck's pain or swelling and 79 cases presented with gastrointestinal symptoms. Pain or swelling of salivary gland occurred in 15 patients, headache and vertigo in 10, insomnia in 9, vocal cord paralysis in 6, fatigue or general malaise in 6, and foreign body sensation in 5. Body numbness and urinary symptoms were observed in only 1 case, respectively. Those side effects were related with sex, pre-I-131 treatment TSH levels, frequency of I-131 therapy, and lymph node metastases. Conclusions. Short-term side effects after I-131 therapy for DTC patients varied individually; severe symptoms were not uncommon but generally did not need emergent medical intervention. PMID:26989683

    Full Text Available A 57 year-old-woman, with no previous history of dyslipedemia, developed severe hypertriglyceridemia while being treated with capecitabine for metastatic breast cancer. Capecitabine was not discontinued and serum triglyceride levels were normalized after 4 weeks of treatment with fenofibrate. Capecitabine induced hypertriglyceridemia, as a rare drug-related side effect, seems to be often overlooked by clinicians.

    Patients with cancer utilize complementary and alternative medicine (CAM) for a variety of purposes, one of which is the reduction of side effects of conventional treatment. With a large number of their patients using CAM, it is important for advanced practitioners in oncology to have an understanding of these therapies to better guide their patients. Side effects of radiation therapy that may have dose-limiting poten-tial include diarrhea, mucositis, skin toxicity, and xerostomia. A com-mon side effect that is not necessarily dose-limiting but considerably troublesome to patients is cancer- and treatment-related fatigue. The CAM therapies that may alleviate some of the side effects of radiation therapy include probiotics, psyllium, exercise, melatonin, honey, acu-puncture, and calendula. Therapies that require more research or have been shown to be ineffective include aloe vera, glutamine, and deglyc-yrrhizinated licorice. This article provides an overview of these thera-pies as well as related research and analysis. PMID:25032003

    Cannabidiol (CBD), a major nonpsychotropic constituent of Cannabis, has multiple pharmacological actions, including anxiolytic, antipsychotic, antiemetic and anti-inflammatory properties. However, little is known about its safety and side effect profile in animals and humans. This review describes in vivo and in vitro reports of CBD administration across a wide range of concentrations, based on reports retrieved from Web of Science, Scielo and Medline. The keywords searched were "cannabinoids", "cannabidiol" and "side effects". Several studies suggest that CBD is non-toxic in non-transformed cells and does not induce changes on food intake, does not induce catalepsy, does not affect physiological parameters (heart rate, blood pressure and body temperature), does not affect gastrointestinal transit and does not alter psychomotor or psychological functions. Also, chronic use and high doses up to 1,500 mg/day of CBD are reportedly well tolerated in humans. Conversely, some studies reported that this cannabinoid can induce some side effects, including inhibition of hepatic drug metabolism, alterations of in vitro cell viability, decreased fertilization capacity, and decreased activities of p-glycoprotein and other drug transporters. Based on recent advances in cannabinoid administration in humans, controlled CBD may be safe in humans and animals. However, further studies are needed to clarify these reported in vitro and in vivo side effects. PMID:22129319

    Full Text Available Finasteride is in present a relatively frequent prescribed drug for male androgenic alopecia. The adverse effects reported by some patients seem to be notable, consisting of various (physical, mental/ neurological, sexual, etc. manifestations which are encountered both during Finasteride administration and after treatment cessation (in the form of `post-Finasteride syndrome`. The pharmacological action and the corresponding adverse effects related to Finasteride administration were investigated and published in literature through several and successive studies. In respect to psychiatric disorders, the most notable concern is related to depressive symptoms and suicidal thoughts among former users of finasteride with persistent adverse effects. Regarding genito-urinary symptoms, these are usually represented by gynecomastia, decreased interest in sexual intercourse/ low level of sexual desire and erectile dysfunction. Finally, we viewed Finasteride side effects and post-Finasteride syndrome as distinct physiopathologic entities, thus requiring possible distinct therapeutic approaches. Additional studies will be necessary, in order to further investigate the cerebral neuromodulation of the two relational (cognitive and sexual functions, both of which may be interfered by administration of hormones or by the corresponding compounds such as Finasteride.

    Full Text Available Objective: to provide a systematic review of the adverse reactions of sorafenib, sunitinib, and temsirolimus and to outline actions for their prevention and correction.Materials and methods. To provide a description of the main methods to decrease the toxicity of these drugs, the authors made a systemat- ic review of their adverse reactions, by using the publications available in the PubMed database, monographs on the medicines, and instruc- tions for their medical use. Results. The frequency of their adverse reactions varied from < 1 to 72%. Grades III—IV side effects are noted more rarely; their incidence is < 1 to 13% for sorafenib, < 1 to 16% for sunitinib, and 1 to 20% for temsirolimus. Sinitinib causes most grades III—IV adverse reactions and sofafenib does the least. However, close comparative studies of the safety of these kinase inhibitors are still lacking. Virtually all side effects can be effectively prevented and treated.  Conclusion. The prevention, timely recognition, and treatment of the adverse reactions of these agents are of great importance, which allows avoidance of the unneeded dosage reduction that may result in worse therapeutic efficiency.   

  13. Adverse Effects and Toxicity of the Atypical Antipsychotics: What is Important for the Pediatric Emergency Medicine Practitioner

    Rasimas, J.J.; Liebelt, Erica L.

    2012-01-01

    Medications are being used with greater frequency to address pediatric mental health problems, and in recent years atypical antipsychotic (AAP) prescriptions have increased more than any other class. Acute care practitioners must be aware of the pharmacology of AAPs and the conditions, on- and off-label, for which they are prescribed. This involves identifying and managing side effects that manifest both mentally and physically. Although “atypicality” confers a lower risk of movement side effects compared to conventional agents, children are more sensitive than adults to extrapyramidal reactions. Like adults, they also may present with toxic sedation, confusion, cardiovascular dysfunction, and metabolic derangements. Evaluation and management of these toxicities requires an index of suspicion, a careful symptom and medication history, physical examination, and targeted interventions. This review is designed to orient the emergency practitioner to the challenging task of recognizing and treating adverse effects related to acute and chronic atypical antipsychotic exposure in children.

    Almost all clinically used antitumor drugs exhibit toxic side effects affecting heart function. Because of cardiotoxicity during anticancer chemotherapy, effective doses of cytostatics have to be limited, which may worsen antitumor efficacy. The cardiotoxicity induced by cytostatics of the anthracycline group in particular results, among others, from massive stimulation of ROS. It has therefore been suggested that some phytochemicals with high antioxidant potential, when administered together...

    2014-07-01

    Full Text Available Gian Maria Pacifici Medical School, Department of Translational Research and New Technologies in Medicine and Surgery, Section of Pharmacology, University of Pisa, Pisa, Italy Objective: The objective of this study was to evaluate the extent of renal adverse effects caused by ibuprofen or indomethacin in order to choose the safer drug to administer to preterm infants. Methods: The following three parameters of renal function were taken into consideration: 1 the urine output; 2 the serum creatinine concentration; and 3 the frequency of oliguria. The bibliographic search was performed using PubMed and Embase databases as search engines. Results: Urine output ranged from 3.5±1.2 to 4.0±1.4 mL/kg/h after ibuprofen treatment, and from 2.8±1.1 to 3.6±1.4 mL/kg/h after indomethacin treatment. The values for ibuprofen are significantly (P<0.05 higher than those for indomethacin. The serum creatinine concentrations ranged from 0.98±0.24 to 1.48±0.2 mg/dL after ibuprofen treatment, and from 1.06±0.24 and 2.03±2.10 mg/dL after indomethacin treatment. The values for ibuprofen are significantly (P<0.05 lower than those for indomethacin. The frequency of oliguria ranged from 1.0% to 9.6% (ibuprofen and from 14.8% to 40.0% (indomethacin, and was significantly lower following ibuprofen than indomethacin administration. In infants with body weight lower than 1,000 g, oliguria appeared in 5% (ibuprofen and 40% (indomethacin; P=0.02. Conclusion: Indomethacin is associated with more severe renal adverse effects than ibuprofen. Ibuprofen is less nephrotoxic than indomethacin and should be used to treat patent ductus arteriosus in preterm infants. Immaturity increases the frequency of adverse effects of indomethacin. Keywords: ibuprofen, indomethacin, patent-ductus-arteriosus, renal-side-effects

    Effects of Timing of Adversity on Adolescent and Young Adult Adjustment Abstract Exposure to adversity during childhood and adolescence predicts adjustment across development. Further, adolescent adjustment problems persist into young adulthood. This study examined relations of contextual adversity with concurrent adolescent adjustment and prospective mental health and health outcomes in young adulthood. A longitudinal sample (N = 808) was followed from age 10 through 27. Perceptions of neighborhood in childhood predicted depression, alcohol use disorders, and HIV risk in young adulthood. Further, the timing of adversity was important in determining the type of problem experienced in adulthood. Youth adjustment predicted adult outcomes, and in some cases, mediated the relation between adversity and outcomes. These findings support the importance of adversity in predicting adjustment and elucidate factors that affect outcomes into young adulthood. PMID:22754271

    In 1992, the Netherlands Centre for Monitoring of Adverse Reactions to Drugs received 1248 reports of suspected adverse reactions. The most important reports concerned chest pain to sumatriptan, cholestatic hepatitis to itraconazole and taste loss to terbinafine. Other important reports pertained to confusion and hallucinations in children on deptropine, postasphyctic encephalopathy of a newborn after intrapartum administration of nalbuphine, torsades de pointes to terodiline, fever to neuroleptics, muscle necrosis to intramuscular administration of diclofenac, gout during use of acetylsalicylic acid, psychic effects of vigabatrine and sudden death during fluorescence angiography. It is the policy of the Netherlands centre to publish as many relevant reports as possible in order to facilitate medical practitioners to adapt their pharmacotherapeutic choice. In close collaboration with several universities, the Netherlands centre currently develops systems and methods for postmarketing surveillance. PMID:8371825

    Combined antiretroviral treatment (cART) modifications are often required due to treatment failure or side effects. We investigate cART regimens' durability, frequency of treatment-limiting adverse events, and potential risk factors and temporal trends. Data were derived from the Athens Multicenter AIDS Cohort Study (AMACS). Statistical analyses were based on survival techniques, allowing for multiple contributions per individual. Overall, 2,756 individuals, aged >15 years, initiated cART. cART regimens were grouped by their initiation date into four calendar periods (1995-1998, 1999-2002, 2003-2006, and 2007+). Median [95% confidence interval (CI)] time to first treatment modification was 2.11 (1.95-2.33) years; cumulative probabilities at 1 year were 31.6%, 29.0%, 33.1%, and 29.6% for the four periods, respectively. cART modifications were less frequent in more recent years (adjusted HR=0.96 per year; pnonnucleoside reverse transcriptase inhibitor (NNRTI)-based regimens or triple nucleoside reverse transcriptase inhibitor (NRTI)-based cART regimens. Treatment modifications have become less frequent in more recent years. This could be partly attributed to the lower risk for side effects of NNRTI-based cART regimens and mainly to the improved efficacy of newer drugs. However, the rate of drugs substitutions due to adverse events remains substantially high. PMID:25950848

  20. Late side effects of Ruthenium 106 therapy for uveal melanomas

    International Nuclear Information System (INIS)

    When effectiveness is evaluated in brachytherapy with Ruthenium 106 special emphasis has to be put on tumor destruction and late side effects responsible for the definite functional results. We evaluated the late side effects of 22 uveal melanomas, which had been treated with 106 Ruthenium plaques. The tumor prominences ranged from 3 to 10 mm, the diameter from 4 to 9 disc diameters. In 4 patients the tumor involved the posterior pole, 14 melanomas were located in the midperiphery of the fundus, 4 tumors were ciliary body melanomas. The total radiation dose of the apex ranged from 100 to 240 Gy with a corresponding dose to the sclera between 540 to 1000 Gy. Because of the short half life of the plaque we have been using different dose rates (1.6-11 Gy/h). In 17/22 eyes adequate regression could be achieved by Ruthenium therapy alone. In one case additional laser treatment of the macular part of the melanoma had to be performed, Gamma Knife therapy was necessary in another melanoma with 10 mm tumor prominence. 3 recurrences led to enucleation. The mean follow up was 4.8 years ranging from 1 to 7 years. In 2/22 patients opticopathy caused severe visual impairment, in another 2 patients radiation maculopathy and opticopathy was observed. 7/22 developed vasculopathy with neovascularization treated by photocoagulation. In one case of focal radiation maculopathy laser treatment could prevent further visual impairment. The following factors are responsible for a higher incidence of late side effects: 1. High dose rate of the plaques in combination with a high radiation dose to the sclera 2. Location of the tumor within a minimum distance of 2 disc diameters to the optic nerve or macula 3. Tumor location at the ciliary body Laser treatment in case of neovascularization and focal radiation maculopathy is the only effective treatment with regard to late side effects. Ischemic maculopathy and radiation opticopathy are responsible for late visual impairment. (authors)

    Targets for drugs have so far been predicted on the basis of molecular or cellular features, for example, by exploiting similarity in chemical structure or in activity across cell lines. We used phenotypic side-effect similarities to infer whether two drugs share a target. Applied to 746 marketed...... drugs, a network of 1018 side effect-driven drug-drug relations became apparent, 261 of which are formed by chemically dissimilar drugs from different therapeutic indications. We experimentally tested 20 of these unexpected drug-drug relations and validated 13 implied drug-target relations by in vitro...... binding assays, of which 11 reveal inhibition constants equal to less than 10 micromolar. Nine of these were tested and confirmed in cell assays, documenting the feasibility of using phenotypic information to infer molecular interactions and hinting at new uses of marketed drugs....

    Immunotherapies revolutionised the treatment of several disorders but show specific side-effect profiles which frequently involve psychological symptoms. Long term interferon-alpha (IFN-alpha) therapy can cause wide-ranging psychiatric side-effects from fatigue, insomnia, anxiety to full-blown depression. This treatment-emergent depression shares several symptoms with major depressive disorder (MDD) with a predominance of somatic/neurovegetative symptoms, and can be treated with antidepressants. However, this experience directed research to inflammatory mechanisms in MDD. MDD has been confirmed as a heterogeneous disorder with a subgroup of patients suffering from low-grade chronic inflammation and frequently resistant to traditional antidepressant treatment. Thus future research should develop strategies to identify those MDD patients who could benefit from drugs acting through inflammatory pathways. PMID:27456240

    Full Text Available Gold bead implantation has been used for years as an alternative method to improve function in chronic joint disease both in humans and dogs. The aims of the present study were to describe the technique of implanting 24-karat gold beads around the hip joints of dogs with chronic hip dysplasia, and to record any side effects or complications of such treatment. A prospective placebo-controlled double-blinded clinical trial was performed. Eighty dogs were randomly allocated to treatment or placebo, with 38 in the gold implantation group and 42 in the placebo group, and followed intensely for six months. The implantation technique was simple to perform, using fluoroscopy and with the dogs under inhalation anesthesia for about 30 minutes. Adverse effects, measured as pain or discomfort, were seen for a period of up to four weeks in 15 of the dogs in the gold implantation group, compared to six dogs in the placebo group. During implantation, a technical difficulty occurred as 82% of the dogs showed leakage of blood and/or synovia from the needles. The dogs in the gold implantation group were radiographed 18 months later. Of the 30 dogs that were radiographed at both inclusion and 24 months, 80% (24 dogs showed a deterioration of the coxofemoral arthrosis, the other six had stable disease evaluated by radiography.

    Full Text Available Abstract Background To estimate the occurrence and type of adverse effects after application of an extra-articular (soft tissue corticosteroid injection. Methods A systematic review of the literature was made based on a PubMed and Embase search covering the period 1956 to January 2010. Case reports were included, as were prospective and retrospective studies that reported adverse events of corticosteroid injection. All clinical trials which used extra-articular corticosteroid injections were examined. We divided the reported adverse events into major (defined as those needing intervention or not disappearing and minor ones (transient, not requiring intervention. Results The search yielded 87 relevant studies:44 case reports, 37 prospective studies and 6 retrospective studies. The major adverse events included osteomyelitis and protothecosis; one fatal necrotizing fasciitis; cellulitis and ecchymosis; tendon ruptures; atrophy of the plantar fat was described after injecting a neuroma; and local skin effects appeared as atrophy, hypopigmentation or as skin defect. The minor adverse events effects ranged from skin rash to flushing and disturbed menstrual pattern. Increased pain or steroid flare after injection was reported in 19 studies. After extra-articular injection, the incidence of major adverse events ranged from 0-5.8% and that of minor adverse events from 0-81%. It was not feasible to pool the risk for adverse effects due to heterogeneity of study populations and difference in interventions and variance in reporting. Conclusion In this literature review it was difficult to accurately quantify the incidence of adverse effects after extra-articular corticosteroid injection. The reported adverse events were relatively mild, although one fatal reaction was reported.

    2012-01-01

    Advances in fields of inquiry as diverse as neuroscience, molecular biology, genomics, developmental psychology, epidemiology, sociology, and economics are catalyzing an important paradigm shift in our understanding of health and disease across the lifespan. This converging, multidisciplinary science of human development has profound implications for our ability to enhance the life prospects of children and to strengthen the social and economic fabric of society. Drawing on these multiple streams of investigation, this report presents an ecobiodevelopmental framework that illustrates how early experiences and environmental influences can leave a lasting signature on the genetic predispositions that affect emerging brain architecture and long-term health. The report also examines extensive evidence of the disruptive impacts of toxic stress, offering intriguing insights into causal mechanisms that link early adversity to later impairments in learning, behavior, and both physical and mental well-being. The implications of this framework for the practice of medicine, in general, and pediatrics, specifically, are potentially transformational. They suggest that many adult diseases should be viewed as developmental disorders that begin early in life and that persistent health disparities associated with poverty, discrimination, or maltreatment could be reduced by the alleviation of toxic stress in childhood. An ecobiodevelopmental framework also underscores the need for new thinking about the focus and boundaries of pediatric practice. It calls for pediatricians to serve as both front-line guardians of healthy child development and strategically positioned, community leaders to inform new science-based strategies that build strong foundations for educational achievement, economic productivity, responsible citizenship, and lifelong health.

    Full Text Available To evaluate the effectiveness of Uncaria tomentosa in minimizing the side effects of chemotherapy and improving the antioxidant status of colorectal cancer (CRC patients, a randomized clinical trial was conducted. Patients (43 undergoing adjuvant/palliative chemotherapy with 5-Fluorouracil/leucovorin + oxaliplatin (FOLFOX4 were split into two groups: the UT group received chemotherapy plus 300 mg of Uncaria tomentosa daily and the C group received only FOLFOX4 and served as a control. Blood samples were collected before each of the 6 cycles of chemotherapy, and hemograms, oxidative stress, enzymes antioxidants, immunologic parameters, and adverse events were analyzed. The use of 300 mg of Uncaria tomentosa daily during 6 cycles of FOLFOX4 did not change the analyzed parameters, and no toxic effects were observed.

    2013-12-01

    Full Text Available The article examines the general problems of the use of anabolic steroids by athletes. The main reason they are banned in sports is because they artificially increase human performance by stimulating various metabolisms, as well as stimulating the constructive and energetic metabolism processes. The prohibited anabolic steroids are not only harmful to the athletes’ health but they also pose a very real threat to their life. Information regarding the side effects of anabolic steroids can be effectively used while working with athletes, their parents, the coaching staff and sports doctors to keep athletes healthy and to promote the goal of “winning without doping”.

  3. Side Effects Related to 5 α-Reductase Inhibitor Treatment of Hair Loss in Women: A Review.

    2016-04-01

    5 α-reductase inhibitors such as finasteride and dutasteride have been studied for the treatment of hair loss in men, with finasteride being the only Food and Drug Administration-approved treatment. Increasingly, in recent years, off-label use of these drugs has been employed in the treatment of female pattern hair loss (FPHL) and frontal fibrosing alopecia (FFA) in women. Side effects with 5 α-reductase inhibitors can include changes in sexual function, and recent publications have characterized an increasing prevalence of these in men. A review of 20 peer-reviewed articles found that very few side effects, or adverse events, related to sexual function have been reported in studies in which dutasteride or finasteride has been used to treat hair loss in women. Future publications should investigate not only the efficacy of these drugs in treating FPHL and FFA, but the side effect profile in patients as well. PMID:27050696

    Recent years have seen a rapidly increasing trend towards the delivery of health technology through mobile devices. Smartphones and tablet devices are thus becoming increasingly popular for accessing information and a wide range of services, including health care services. Modern mobile apps can be used for a variety of reasons, ranging from education for the patients and assistance to clinicians to delivery of interventions. Mobile phone apps have also been established to benefit patients in a scope of interventions across numerous medical specialties and treatment modalities. Medical apps have their advantages and disadvantages. It is important that clinicians have access to knowledge to make decisions regarding the use of medical apps on the basis of risk-benefit ratio. Mobile apps that deliver psycho social interventions offer unique challenges and opportunities. A number of reviews have highlighted the potential use of such apps. There is a need to describe, report and study their side effects too. The adverse effects associated with these apps can broadly be divided into: (1) those resulting from the security and safety concerns; (2) those arising from the use of a particular psycho social intervention; and (3) those due to the interaction with digital technology. There is a need to refine and reconsider the safety and adverse effects in this area. The safety profile of a mobile PSI app should describe its safety profile in: (1) privacy and security; (2) adverse effects of psychotherapy; and (3) adverse effects unique to the use of apps and the internet. This is, however, a very new area and further research and reporting is required to inform clinical decision making. PMID:27354959

  6. Phytochemicals that counteract the cardiotoxic side effects of cancer chemotherapy

    Directory of Open Access Journals (Sweden)

    Anita Piasek

    2009-04-01

    Full Text Available Almost all clinically used antitumor drugs exhibit toxic side effects affecting heart function. Because of cardiotoxicity during anticancer chemotherapy, effective doses of cytostatics have to be limited, which may worsen antitumor efficacy. The cardiotoxicity induced by cytostatics of the anthracycline group in particular results, among others, from massive stimulation of ROS. It has therefore been suggested that some phytochemicals with high antioxidant potential, when administered together with antitumor agents, could decrease the toxic side effects of chemotherapy and reduce the risk of heart failure. This review summarizes findings of studies undertaken to identify edible plants or phytochemicals isolated from them displaying cardioprotective properties during chemotherapy. Such properties have been shown for such foods as grapes, garlic, tomato, spinach, and beetroot. A protective role on the heart is also displayed by melatonin (a hormone synthesized by the pineal gland, but also present in many edible plants, chalcones (precursors of all known flavonoids, some herbal dietary supplements, vitamins A, C, and E, selenium, and semisynthetic flavonoid 7-monohydroxyethylrutoside (monoHER. Although to date only a limited number of investigations have been carried out, their results suggest that dietary intervention with antioxidants found in edible plants may be a safe and effective way of alleviating the toxicity of anticancer chemotherapy and preventing heart failure.

    Protein kinases are one of the largest gene families and have regulatory roles in all aspects of eukaryotic cell function. Modulation of protein kinase activity is a desirable therapeutic approach for a number of human diseases associated with aberrant kinase activity, including cancers, arthritis and cardiovascular disorders. Several strategies have been used to develop specific and selective protein kinase modulators, primarily via inhibition of phosphorylation and down-regulation of kinase gene expression. These strategies are effective at regulating intracellular signalling pathways, but are unfortunately associated with several undesirable effects, particularly those that modulate ion channel function. In fact, the side-effects have precluded these inhibitors from being both useful experimental tools and therapeutically viable. This review focuses on the ion channel side-effects of several protein kinase inhibitors and specifically on those modulating K+, Na+ and Ca2+ ion channels. It is hoped that the information provided with a detailed summary in this review will assist the future development of novel specific and selective compounds targeting protein kinases both for experimental tools and for therapeutic approaches.

    Recently,novel anti-androgens and inhibitors of androgen biosynthesis have been developed through the elucidation of mechanisms of castration resistance of prostate cancer.We believe that these new developments will improve hormonal therapy.On the other hand,there has been an increase in criticism of hormonal therapy,because hormonal therapy is supposed to induce adverse effects such as cardiovascular disease.In this review,we have introduced the Japanese experience of hormonal therapy,because we believe that there may be ethnic differences between Caucasians and Asian people in the efficacy and adverse effects of hormonal therapy.First,we showed that primary hormonal therapy can achieve long-term control of localized prostate cancer in some cases and that quality of life of patients receiving hormonal therapy is rather better than previously thought.Neoadjuvant and adjuvant hormonal therapy in cases undergoing radical prostatectomy or radiotherapy are very useful for high-risk or locally advanced prostate cancer.Further clinical trials are required to confirm the efficacy of neoadjuvant or adjuvant hormonal therapy.We showed that the death from cardiovascular diseases in Japanese patients receiving hormonal therapy was not higher than that in the general population.However,efforts should be made to decrease the adverse effects of hormonal therapy,because life-style change may increase the susceptibility to adverse effects by hormonal therapy even in Japan.Managements of endocrine and metabolic dysfunction,such as diabetes mellitus,are essential.New hormonal compounds such as selective androgen receptor modulators capable of specifically targeting prostate cancer are expected to be developed.

    Purpose. The use of radiation therapy (RT) together with improvement in the surgical treatment of rectal cancer improves survival and reduces the risk for local recurrences. Despite these benefits, the adverse effects of radiation therapy limit its use. The aim of this review was to present a comprehensive overview of published studies on late adverse effects related to the RT for rectal cancer. Methods. Meta-analyses, reviews, randomised clinical trials, cohort studies and case-control studies on late adverse effects, due to pre- or postoperative radiation therapy and chemo-radiotherapy for rectal cancer, were systematically searched. Most information was obtained from the randomised trials, especially those comparing preoperative short-course 5x5 Gy radiation therapy with surgery alone. Results. The late adverse effects due to RT were bowel obstructions; bowel dysfunction presented as faecal incontinence to gas, loose or solid stools, evacuation problems or urgency; and sexual dysfunction. However, fewer late adverse effects were reported in recent studies, which generally used smaller irradiated volumes and better irradiation techniques; although, one study revealed an increased risk for secondary cancers in irradiated patients. Conclusions. These results stress the importance of careful patient selection for RT for rectal cancer. Improvements in the radiation technique should further be developed and the long-term follow-up of the randomised trials is the most important source of information on late adverse effects and should therefore be continued.

    The purpose of this report is to present a review of the medical uses, efficacy, and adverse effects of the three approved cannabis-based medications and ingested marijuana. A literature review was conducted utilizing key search terms: dronabinol, nabilone, nabiximols, cannabis, marijuana, smoke, efficacy, toxicity, cancer, multiple sclerosis, nausea, vomiting, appetite, pain, glaucoma, and side effects. Abstracts of the included literature were reviewed, analyzed, and organized to identify the strength of evidence in medical use, efficacy, and adverse effects of the approved cannabis-based medications and medical marijuana. A total of 68 abstracts were included for review. Dronabinol's (Marinol) most common medical uses include weight gain, chemotherapy-induced nausea and vomiting (CINV), and neuropathic pain. Nabiximol's (Sativex) most common medical uses include spasticity in multiple sclerosis (MS) and neuropathic pain. Nabilone's (Cesamet) most common medical uses include CINV and neuropathic pain. Smoked marijuana's most common medical uses include neuropathic pain and glaucoma. Orally ingested marijuana's most common medical uses include improving sleep, reducing neuropathic pain, and seizure control in MS. In general, all of these agents share similar medical uses. The reported adverse effects of the three cannabis-based medications and marijuana show a major trend in central nervous system (CNS)-related adverse effects along with cardiovascular and respiratory related adverse effects. Marijuana shares similar medical uses with the approved cannabis-based medications dronabinol (Marinol), nabiximols (Sativex), and nabilone (Cesamet), but the efficacy of marijuana for these medical uses has not been fully determined due to limited and conflicting literature. Medical marijuana also has similar adverse effects as the FDA-approved cannabis-based medications mainly consisting of CNS related adverse effects but also including cardiovascular and respiratory

  12. Pharmacological modulation of late radio-induced side effects

    International Nuclear Information System (INIS)

    After normal tissue exposure to radiation therapy, late side effects can occur and may reduce patients' quality of life due to their progressive nature. Late toxicities occurrence is the main limiting factor of radiotherapy. Various biological disorders related to irradiation are involved in the development of late toxicities including fibrosis. The present review will focus on the recent physiopathological and molecular mechanisms described to be involved in the development of late radio-induced toxicities, that provide therapeutic perspective for pharmaco-modulation.

    Directory of Open Access Journals (Sweden)

    Olajumoke Omolara Ojo

    Full Text Available Salinomycin is used as an antibiotic in animal husbandry. Its implication in cancer therapy has recently been proposed. Present study evaluated the toxic effects of Salinomycin on male reproductive system of mice. Doses of 1, 3 or 5 mg/kg of Salinomycin were administered daily for 28 days. Half of the mice were sacrificed after 24 h of the last treatment and other half were sacrificed 28 days after withdrawal of treatment. Effects of SAL on body and reproductive organ weights were studied. Histoarchitecture of testis and epididymis was evaluated along with ultrastructural changes in Leydig cells. Serum and testicular testosterone and luteinizing hormones were estimated. Superoxide dismutase, reduced glutathione, lipid peroxidation, catalase and lactate dehydrogenase activities were measured. Spermatozoa count, morphology, motility and fertility were evaluated. Expression patterns of steroidogenic acute regulatory protein (StAR and cytochrome P450 side chain cleavage proteins (CYP11A1 were assessed by Western blotting. Salinomycin treatment was lethal to few mice and retarded body growth in others with decreased weight of testes and seminal vesicles in a dose dependent manner. Seminiferous tubules in testes were disrupted and the epithelium of epididymis showed frequent occurrence of vacuolization and necrosis. Leydig cells showed hypertrophied cytoplasm with shrunken nuclei, condensed mitochondria, proliferated endoplasmic reticulum and increased number of lipid droplets. Salinomycin decreased motility and spermatozoa count with increased number of abnormal spermatozoa leading to infertility. The testosterone and luteinizing hormone levels were decreased in testis but increased in serum at higher doses. Depletion of superoxide dismutase and reduced glutathione with increased lipid peroxidation in both testis and epididymis indicated generation of oxidative stress. Suppressed expression of StAR and CYP11A1 proteins indicates inhibition of

  16. Side effects and hazards of contrast media lymphography

    International Nuclear Information System (INIS)

    In 809 patients, side effects following lymphography were found by routine X-ray checks of the lungs and andon account of the case reports, and compared with other authors' publications. The most frequant complication was a microembolism of the lungs (established by X-ray in 367 patients). 209 patients were free of clinical signs, while clinical changes were manifest in 232. No serious complications like cerebral embolism or decease were recorded. Among the remaining general side effects there was a transitory temperature increase in 249 patients altogether (1 centigrade for up to 24 hours). The further complications consisted mainly in a rise in pulse frequency (170), general subjective impression of sickness (106), shivering cold (22) and respiratory trouble (5). Skin reactions and complications regarding the lymph nodes and lymphatic channels were only exceptionally seen. No special age group turned out to be more than averagely at risk. The steady decrease in the rate of complications from 1965 (73 per cent) to 1974 with a final rate of 41 per cent in autumn 1974 was a notable fact. (orig./MG)

  19. Concrete blocks' adverse effects on indoor air and recommended solutions

    International Nuclear Information System (INIS)

    Air infiltration through highly permeable concrete blocks can allow entry of various serious indoor air pollutants including radon. An easy approach to avoiding these pollutants is to select a less-air-permeable concrete block. Tests show that air permeability of concrete blocks can vary by a factor greater than 50 (0.63--35 standard L/min/m2 at 3 Pa). The surface texture of the blocks correlates well with air permeability; test results of smoother, closed-surface-texture blocks were usually less air-permeable. During construction, air infiltration can be minimized by capping walls and carefully sealing around openings for utilities or other penetrations. Structures with indoor air-quality problems due to soil-gas entry can be mitigated more effectively with less coating material if the blocks have a closed surface texture. All coatings evaluated--cementaceous block filler (which has the lowest applied cost and is more than 99.5% effective), surface bonding cement, water-based epoxy, polysulfide vinyl acrylic, and latex (three coats)--were highly effective (more than 98%) in reducing air permeability when adequately applied. Coating selection should be influenced by expected service life, considering surface condition and cost

    Despite India's substantial progress in human development since its independence in 1947, 5-7% of its children have vitamin A deficiency disorders in selected geographic areas, 53% have iron deficiency anemia, and 9% have goiter. Three micronutrients--vitamin A, iron, and iodine--are among the most important of all the nutrients needed by the body because they are vital for developing normal learning and cognitive functions, immunity, work capacity, and reproductive health. The body cannot synthesize them, so they must be made available through the diet. Deficiencies of these three micronutrients are known to have devastating effects on health. PMID:12035866

  3. The Adverse Effects of Alcohol on Vitamin A Metabolism

    Directory of Open Access Journals (Sweden)

    William S. Blaner

    2012-05-01

    Full Text Available The objective of this review is to explore the relationship between alcohol and the metabolism of the essential micronutrient, vitamin A; as well as the impact this interaction has on alcohol-induced disease in adults. Depleted hepatic vitamin A content has been reported in human alcoholics, an observation that has been confirmed in animal models of chronic alcohol consumption. Indeed, alcohol consumption has been associated with declines in hepatic levels of retinol (vitamin A, as well as retinyl ester and retinoic acid; collectively referred to as retinoids. Through the use of animal models, the complex interplay between alcohol metabolism and vitamin A homeostasis has been studied; the reviewed research supports the notion that chronic alcohol consumption precipitates a decline in hepatic retinoid levels through increased breakdown, as well as increased export to extra-hepatic tissues. While the precise biochemical mechanisms governing alcohol’s effect remain to be elucidated, its profound effect on hepatic retinoid status is irrefutable. In addition to a review of the literature related to studies on tissue retinoid levels and the metabolic interactions between alcohol and retinoids, the significance of altered hepatic retinoid metabolism in the context of alcoholic liver disease is also considered.

    2016-01-01

    Long-term antidepressant treatment has increased and there is evidence of adverse effects; however, little is known about patients’ experiences and views of this form of treatment. This study used mixed methods to examine patients’ views and experiences of long-term antidepressant treatment, including benefits and concerns. Data from 180 patients, who were long-term users of antidepressants (3–15 years), were extracted from an anonymous online survey of patients’ experiences of antidepressants in New Zealand. Participants had completed rating scales about the effectiveness of antidepressants, levels of depression before and during antidepressant use, quality of life, and perceived adverse effects. Two open-ended questions allowed participants to comment on personal experiences. The majority (89.4%) reported that antidepressants had improved their depression although 30% reported moderate-to-severe depression on antidepressants. Common adverse effects included withdrawal effects (73.5%), sexual problems (71.8%), and weight gain (65.3%). Adverse emotional effects, such as feeling emotionally numb (64.5%) and addicted (43%), were also common. While the majority of patients were pleased with the benefits of antidepressant treatment, many were concerned about these adverse effects. Some expressed a need for more information about long-term risks and increased information and support to discontinue. PMID:27528803

    consumption of pilot whale meat. METHODS: We assessed exposure levels from mercury analysis of toenails and whole blood (obtained at the time of clinical examination), and a hair sample collected 7 years previously. Outcome measures included heart rate variability (HRV), blood pressure (BP), common carotid...... intima-media thickness (IMT), and brainstem auditory evoked potentials (BAEP). We carried out multiple regression and structural equation model (SEM) analyses to determine the confounder-adjusted effect of mercury exposure. Taking into account correlations among related measures, we categorized exposure...... and outcomes in groups to derive latent exposure and response variables in SEMs. We used multiple regression analysis to compare the predictive validity of individual exposure biomarkers and the latent exposure variable on individual and latent outcomes. RESULTS: The toenail mercury concentrations...

    Full Text Available This study aims to determine the effects of the automotive industry on carbon dioxide emissions for the period from 1997 to 2010 for diverse economies, as well as the relationships between carbon dioxide discharges and output. The study applies cointegration and causality tests to validate these associations. The results of the Johansen cointegration test depict long-run associations between the quantity of passenger cars and carbon dioxide emissions in France, Sweden, Spain, Hungary and Japan. In addition, significant relations were observed between output and carbon dioxide discharges in Spain, Canada, India and Japan. Changes in output had substantial impact on emissions in Germany, Canada and India. The results also show that the number of passenger cars influences the magnitude of emissions in multiple economies. In conclusion, the automotive industry has to be considered in policies that aim to reduce carbon dioxide emissions.

  7. Hyperbaric oxygen (HBO) in the treatment of radiation side effects

    International Nuclear Information System (INIS)

    Aim: Many reports show that late complications of radiotherapy can be successfully treated by hyperbaric oxygen (HBO). This synopsis attempts to review the literature to identify areas of clinical use and further research. Patients and Methods: Clinical and experimental data about HBO treatment of radiation late effects are analysed. Mechanisms of hyperbaric oxygen in the treatment of late radiation side effects are discussed. Results: There is evidence in the literature that HBO is beneficial in the treatment of radiation cystitis, osteoradionecrosis of the mandible, hemorrhagic proctitis, soft tissue necrosis and neurologic deficits. The prophylactic use of HBO has shown to prevent the development of osteoradionecrosis after tooth removal and the loss of titanium implants in irradiated facial bones. The physiologic basis of HBO can be referred to induction of neoangiogenesis and revascularisation. Conclusions: Clinicians can be encouraged to use hyperbaric oxygen for the treatment of radiation cystitis, osteonecrosis of the mandible, hemorrhagic proctitis, soft tissue necrosis and neurologic deficits following radiation therapy.

  8. Prophylaxis and therapy of local side effects of maxiliofacial radiotherapy

    International Nuclear Information System (INIS)

    In Europe, malignant growths of the maxiliofacial region account for about 3% of all malignant growths. Many patients are treated by radiotherapy, either before surgery, after surgery, as sole therapy, or in combination with chemotherapy. Depending on the technique applied and on the general and local situation of the patient, reactions of the surrounding normal tissue may be observed. These side effects may occur as early or late reactions of the teeth, mucous membranes, periodontium, salivary glands, and bones. In addition, alcohol, nicotine abuse, or generalized disorders may change the prognosis for the worse and aggravate local complications. If radiotherapy is interrupted for any of these reasons, this will of course interfere with the healing process. In consequence, both the radioconsologist and the dentist must know about the effects of ionizing radiation on the different types of tissue in the maxiliofacial region in order to assure early detection and treatment of complications and information of the patient.

    The fluoroquinolones have been extensively used in the neutropenic patient. When fluoroquinolone monotherapy was used as prophylaxis, frequently for extended periods, the rate of adverse effect of ciprofloxacin (6.9%) ofloxacin (11.6%) and norfloxacin (5.5%) were significantly lower than those of the comparator agents--co-trimoxazole, vancomycin and polymycin. Rash and gastrointestinal upset were the commonest adverse effects associated with the fluoroquinolones. When used as monotherapy for bacterial infections, often intravenously and in high dosages, the cumulative rate of adverse effects caused by the fluoroquinolones (12.6%) was similar to that caused by the comparator agents (10.3%), but significantly higher than reported for non-neutropenic patients (6.4%) and for prophylactic use. The main adverse events were also rashes (15.4%) and gastrointestinal upset (6.1%). When fluoroquinolones were used as therapy of bacterial infections in combination with other agents, the incidence of adverse events was 14.9%, which was similar to the comparator agents (13.5%). Adverse events were also similar except that nephrotoxicity was commonest with comparator combinations (4.0%). The data suggest that fluoroquinolone prophylaxis in neutropenic patients, even for prolonged periods, is safer than the comparator agents, but is associated with more frequent adverse events than in non-neutropenic patients. Fluoroquinolone therapy, frequently with high dosages, is associated with similar rate of adverse events as the comparator agents. When used in combination with the other antibiotics, fluoroquinolones are as safe as the comparator agents. PMID:7961217

    Full Text Available Objectives: Chelating agents remain the mainstay in reducing the iron burden and extending patient survival in homozygous beta-thalassemia but adverse and toxic effects may increase with the institution and long term use of this essential therapy. This study aimed to estimate the incidence of deferasirox (DFX side effects in patients with thalassemia major or intermedia.Methods: A retrospective study of 72 patients (mean age: 20.3±0.9 yrs; 36 male, 36 female with thalassemia major or intermedia treated at Sultan Qaboos University Hospital, Oman, was performed to assess the incidence of side effects related to deferasirox over a mean of 16.7 month follow-up period.Results: Six patients experienced rashes and 6 had gastro-intestinal upset. DFX was discontinued in 18 patients for the following reasons: persistent progressive rise(s in serum creatinine (7 patients; 40% mean serum creatinine rise from baseline, feeling unwell (2, severe diarrhea (1, pregnancy (1, death unrelated to chelator (2 and rise in serum transaminases (2. Three patients were reverted to desferoxamine and deferiprone combination therapy as DFX was no longer biochemically effective after 18 months of therapy. There was no correlation between baseline serum ferritin and serum creatinine or a rise in serum creatinine. Cardiac MRI T2* did not change with DFX therapy. However, there was an improvement in liver MRI T2* (p=0.013.Conclusion: Renal side effects related to deferasirox appear to be higher than those reported in published clinical trials. Further larger studies are required to confirm these findings.

The questions related specifically to effects on daily life, blurring of vision, stinging, irritation, and acceptability compared with any drops previously used. Respondents were asked to grade their answers to these questions using a numerical scale from 0 to 10.Results: Seventy-six patients (100% responded, comprising 58 females and 18 males, aged 68–95 years, treated for 3–7 months. Quality of life was not significantly affected, with the majority of patients recording a response between 0 and 2. Visual blurring was a more prominent feature, with the most common scores being 3 and 4. Stinging did not appear to be a prominent feature, with 0 as the most common response. Similarly, irritation was not a common finding, with most respondents scoring 0 and 1. Finally, the brinzolamide-timolol suspension compared favorably with previously used drops, with the vast majority of patients expressing a preference for this suspension over other topical medications.Conclusion: Brinzolamide-timolol suspension appears to be a well tolerated and acceptable medication, with minimal effect on patient quality of life.Keywords: intraocular pressure, glaucoma, quality of life, side effects

  12. Remembering Statins: Do Statins Have Adverse Cognitive Effects?

    Science.gov (United States)

    Bitzur, Rafael

    2016-08-01

    The issue of statin-associated cognitive impairment has been a hot topic among both patients and health care providers, especially since the U.S. Food and Drug Administration (FDA) issued a statement regarding rare postmarketing reports of ill-defined cognitive impairment associated with statin use. This statement was based on case reports, and no objective measures of cognitive function were used. Nevertheless, many patients at high risk of cardiovascular disease have expressed concerns about possible cognitive decline and may have opted to forgo statin therapy. In this overview, the evidence leading to the statement by the FDA is reviewed. Potential mechanisms of the effect of LDL cholesterol reduction and statin therapy on cognition are discussed. Evidence from observational and prospective randomized trials is summarized, leading to the conclusion that as for now, there is no good evidence that statins cause cognitive impairment to a significant degree. Reported cases seem to be rare, and a causal relationship has not been established. PMID:27440840

    Full Text Available We studied the effects of advanced glycation end products (AGEs, which are known to accumulate in patients with diabetes, autoimmune diseases, or those who smoke, on embryonal development. Pronuclear (PN embryos were obtained by flushing the fallopian tubes of rats after superovulation and mating. The cleavage rate and blastocyst yield were evaluated at 24, 72, 96, and 120 h of culture. Glyoxal, an AGE-forming aldehyde, suppressed embryonal development at every stage from PN to blastocyst in a concentration-dependent manner. The cleavage rate of the embryo was also signifi cantly decreased by treatment with glyoxal at concentrations of 1 mM or higher. The blastocyst yield was significantly decreased by treatment with glyoxal at concentrations of 0.5 mM or higher. N-acetyl-L-cysteine (L-NAC at 1 mM significantly suppressed the glyoxal-induced embryonal toxicity. BSA-AGEs at 5 microg/ml or higher concentration signifi cantly reduced the cleavage rate and blastocyst yield compared to those for BSA-treated embryos. L-NAC at 1 mM significantly suppressed BSAAGE-induced embryonal toxicity. Because AGEs are embryo-toxic, AGE contamination may influence the pregnancy rate of in vitro fertilization and embryo transfer. AGEs, which are increased in women under pathological conditions, may also be involved in their infertility.

    2013-01-01

    Full Text Available Abstract Background Post-treatment follow-up visits for gynecological cancer survivors should provide opportunities for management of adverse physical/psychological effects of therapy and early recurrence detection. However, the adequacy of such visits in Japan is poorly documented. We qualitatively explored care-seeking experiences of Japanese gynecological cancer survivors and deduced factors influencing care-seeking behaviors and treatment access. Methods We conducted 4 semi-structured focus groups comprising altogether 28 Japanese gynecological cancer survivors to collect a variety of participants’ post-treatment care-seeking behaviors through active interaction with participants. Factors influencing access to treatment for adverse effects were analyzed qualitatively. Results Survivors sought care through specialty clinic visits when regular post-treatment gynecological follow-ups were inadequate or when symptoms seemed to be non-treatment related. Information provided by hospital staff during initial treatment influenced patients’ understanding and response to adverse effects. Lack of knowledge and inaccurate symptom interpretation delayed help-seeking, exacerbating symptoms. Gynecologists’ attitudes during follow-ups frequently led survivors to cope with symptoms on their own. Information from mass media, Internet, and support groups helped patients understand symptoms and facilitated care seeking. Conclusions Post-treatment adverse effects are often untreated during follow-up visits. Awareness of possible post-treatment adverse effects is important for gynecological cancer survivors in order to obtain appropriate care if the need arises. Consultation during the follow-up visit is essential for continuity in care.

  17. Tripeptide tyroserleutide plus doxorubicin: therapeutic synergy and side effect attenuation

    International Nuclear Information System (INIS)

    Tripeptide tyroserleutide (YSL) is a novel small molecule anti-tumor polypeptide that has been shown to inhibit the growth of human liver cancer cells. In this study, we investigated the effects of YSL plus doxorubicin on the growth of human hepatocellular carcinoma BEL-7402 cells that had been transplanted into nude mice. Nude mice bearing human hepatocellular carcinoma BEL-7402 tumors were treated with successive intraperitoneal injections of saline; low-, mid-, or high-dose doxorubicin; or low-, mid-, or high-dose doxorubicin plus YSL. Effects on the weight and volume of the tumors were evaluated. Co-administration of YSL and high-dose doxorubicin (6 mg/kg every other day) prolonged the survival time of tumor-bearing mice as compared to high-dose doxorubicin alone. As well, the anti-tumor effects of mid- and low-dose doxorubicin (2 and 0.7 mg/kg every other day, respectively) were enhanced when supplemented with YSL; the tumor growth inhibition rates for YSL plus doxorubicin were greater than the inhibition rates for the same dosages of doxorubicin alone. The combination of YSL and doxorubicin decreased chemotherapy-associated weight loss, leukocyte depression, and heart, liver, and kidney damage as compared to doxorubicin alone. The combination of YSL plus doxorubicin enhances the anti-tumor effect and reduces the side effects associated with doxorubicin chemotherapy

  19. Side-effects of improving CERN's spam filter

    CERN Multimedia

    2004-01-01

    To further improve the fight against spam (unsolicited email), CERN implemented in June a mechanism that returns electronic mail messages to the sender if the originating server is wrongly configured. This "reverse DNS lookup" is an increasingly widespread technique to identify whether the sending e-mail server is legitimate and has a valid host name. This change has nearly doubled the spam rejection efficiency at CERN. However, it has a known side-effect. A small number of correspondents are sending legitimate electronic mail to CERN from mail servers that are incorrectly configured (in technical terms, they do not have a reverse DNS registration). These persons will have their messages returned to them with an error message, provided their sender address is valid. The typical error message that the correspondent receives in such cases is "Relaying denied. No reverse DNS configured for IP". If a correspondent complains to you that emails they are sending you at CERN are being returned with...

  20. Side effect of cranial radiation in childhood acute leukemia, 1

    International Nuclear Information System (INIS)

    We examined the somnolence syndrome, which is one of the side effects of cranial irradiation. Out of 53 patients in acute leukemia who had received cranial irradiation, nine patients (17%) developed the somnolence syndrome. Patients with the somnolence syndrome showed slow waves on EEG. Some patients had ventricular dilatation and widening of sulci before cranial irradiation on CT findings, but these findings improved after cranial irradiation. Out of nine cases with the somnolence syndrome, 6 patients survived and did not experience difficulties in school. But one patient showed calcification on CT brain scan. It is considered that the cause of the somnolence syndrome is a trasient inhibition of myelin synthesis and most patients improved without serious sequelae. It is necessary to follow up many cases of somnolence syndrome. (author)

    2016-03-01

    Approximately 60-70% of Armed Forces personnel consume a dietary supplement (DS) at least once a week and there have been numerous reports of severe adverse events among DS users. This study assessed patterns of DS use and self-reported side-effects among 4400 Armed Forces personnel using a paper-and-pencil survey. Multivariable logistic regression was used to examine associations between patterns of DS use and self-reported side-effects. Sixty-nine percent of personnel surveyed reported using a DS. Seven percent of DS users reported experiencing abnormal heart beats, 6% tremors, 5% stomach pain, 3% dizziness, and 3% numbness/tingling and they believed these symptoms were associated with the use of DS. After adjustment for use of other DS classes, total supplement use, and demographic characteristics, protein supplement users were more likely than non-users to report numbness/tingling; combination product users were more likely to report experiencing abnormal heart beats, stomach pain, dizziness, tremors, and numbness/tingling; and users of purported steroid analogues were more likely to report dizziness. Use of more than one DS per week was associated with an increased likelihood of reporting side-effects. Respondents with a higher body mass index were more likely to report side-effects. Further research is necessary to determine whether self-reported side-effects associated with multiple DS use and some DS classes impact the long-term health or performance of service members. Surveillance of military populations using surveys like this one may provide a method for detecting adverse health events of DS before they are apparent in the civilian population.

    Full Text Available Abstract Background and purpose Targeted drugs have augmented the cancer treatment armamentarium. Based on the molecular specificity, it was initially believed that these drugs had significantly less side effects. However, currently it is accepted that all of these agents have their specific side effects. Based on the given multimodal approach, special emphasis has to be placed on putative interactions of conventional cytostatic drugs, targeted agents and other modalities. The interaction of targeted drugs with radiation harbours special risks, since the awareness for interactions and even synergistic toxicities is lacking. At present, only limited is data available regarding combinations of targeted drugs and radiotherapy. This review gives an overview on the current knowledge on such combined treatments. Materials and methods Using the following MESH headings and combinations of these terms pubmed database was searched: Radiotherapy AND cetuximab/trastuzumab/panitumumab/nimotuzumab, bevacizumab, sunitinib/sorafenib/lapatinib/gefitinib/erlotinib/sirolimus, thalidomide/lenalidomide as well as erythropoietin. For citation crosscheck the ISI web of science database was used employing the same search terms. Results Several classes of targeted substances may be distinguished: Small molecules including kinase inhibitors and specific inhibitors, antibodies, and anti-angiogenic agents. Combination of these agents with radiotherapy may lead to specific toxicities or negatively influence the efficacy of RT. Though there is only little information on the interaction of molecular targeted radiation and radiotherapy in clinical settings, several critical incidents are reported. Conclusions The addition of molecular targeted drugs to conventional radiotherapy outside of approved regimens or clinical trials warrants a careful consideration especially when used in conjunction in hypo-fractionated regimens. Clinical trials are urgently needed in order to

We intend to present in this study several oral adverse effects encountered during finasteride administration, represented by mild and moderate signs which generally responded to topical procedures without to require the stop of the drug administration. New studies on large samples will further document the existing relation between the described oral adverse effects and the implied pathophysiological mechanisms. For this moment, we are taking into account as possible mechanisms- a direct action of finasteride administration, possible indirect consequences due to hormonal interferences, or coexisting factors with finasteride administration that were not detected.

    The clinical spectrum of muscle- and skeletal-related side-effects of statins includes varied myalgias and weakness, an asymptomatic increase in the concentration of creatine kinase and other biochemical parameters, myositis and rhabdomyolysis. Currently, there is no consensus on the definition of 'statin myopathy'. Evidence suggests that deleterious effects may also be associated with the volume or dosage of structured exercise and/or the intensity of physical activity. Moreover, non-muscle adverse effects on the joints and tendons are often overlooked and underemphasized. The incidence of myopathy associated with statin treatment typically ranges between 1.5% and 10%. Few data are available regarding the prevalence of muscle- related symptoms associated with different statins and the distribution of affected muscles. Furthermore, discrepancies between clinical trials and daily practice may emanate, in part, because of inconsistent definitions or exclusion criteria.The pathophysiology of statin-related myopathy is incompletely understood. A dose-dependent and proapoptotic effect, direct effects on mitochondria, drug interactions and genetic factors, or combinations thereof, may be involved. Recently, a rare immune-mediated myopathy triggered by statin use has been described. With the increasing number of patients treated with statins and with more patients being prescribed high doses of potent statins to achieve low-density lipoprotein targets, muscle-related side-effects will become more prevalent. Currently, the only effective treatment is the discontinuation of statin use. Further research is needed to develop alternative LDL-lowering drugs when statins are not well tolerated and to establish additional effective strategies to manage lipids and lipoproteins.

In order to determine the adverse effects of intravenous immunoglobulin inpatients with antibody deficiency, 45 immunodeficientpatients receiving intravenous immunoglobulin were studied during a 36-month period at Children's Medical Center. The investigated group included 25 patients with common variable immunodeficiency, 14 patients with X-linked agammaglobulinemia and 6 patients with IgG subclass defi¬ciency. A total of fifty adverse effects occurred through 955 infusions (5.2%. The most frequent immediate adverse effects were mild (40 infusions out of 955 in 22 cases, including: chills, flushing, fever, nausea and headache. Three patients experienced mod¬erate effects (10 infusions out of 955 such as rash, severe headache, joint pain and chest tightness. None of the effects was anaphylactic type. It can be concluded that intravenous immunoglobulin is generally a well-tolerated medical agent for patients with antibody deficiency, but all patients should be monitored by a physician who is familiar with its indications, risks, adverse effects and their appropriate management.

    Full Text Available Introduction: Today, due to the broad spectrum of pediatric cancers are treated by the chemotherapy drugs, but these drugs have side effects and gastrointestinal toxicity is the most prevalent. One of the main roles of nurses is to better health through patient education and care for him. Evidence-based nursing is a process during which the nurse can use the available research evidence, their clinical expertise and the patient has to take appropriate decisions. This study reviews the role of evidence-based nursing in the prevention of gastrointestinal side effects of chemotherapy in children with cancer was conducted.   Materials and Methods: Seeking information was performing through databases PubMed, SID, Since Direct, magiran, Ovid and etc. Within the years 2014-2002, the key issues in terms of evidence-based nursing, gastrointestinal side effect, chemotherapy was performed and 20 were studied English equivalents.   Results: The most common gastrointestinal side effects in children undergoing chemotherapy are oral ulcers, vomiting, diarrhea, and dysphagia. Different strategies for prevention studies suggest that these effects need to perform their roles in teaching and nursing care. Nurses can use the results of studies such as music, ginger, semi sitting positions during chemotherapy, use of ice and etc. To prevent vomiting, the use of  Persica for oral wound healing, hygiene perform especially hand washing for preventing diarrhea. The most important roles of nursing are recommended, Education on prevention of chemotherapy complications, adverse effects of proper nutrition and etc.   Conclusion: Nurses can play an effective role in the education and care to relieve symptoms and prevent progression of gastrointestinal side effects of chemotherapy.   Key words: Evidence-based nursing, Gastrointestinal side effects, Chemotherapy, Cancer

    This article examines the possible adverse effects of well-intended climate policies. A weak Green Paradox arises if the announcement of a future carbon tax or a sufficiently fast rising carbon tax encourages fossil fuel owners to extract reserves more aggressively, thus exacerbating global warming. We argue that such policies may also encourage more fossil fuel to be locked in the crust of the earth, which can offset the adverse effects of the weak Green Paradox. We show that a subsidy on cl...

    Acne fulminans is a rare and severe form of acne that may evolve from acne vulgaris, especially in male adolescents, or occur as an adverse effect of oral isotretinoin. Arthritis is a serious clinical manifestation when the musculoskeletal system is compromised by AF and has been reported as a rare adverse effect of isotretinoin. Involvement of the sacroiliac joints occurs in 21% of acne fulminans cases. We present the case of a 18-year-old male patient in whom acne fulminans evolved from acn...

  12. Iohexol and iopamidol myelography in the dog: a clinical trial comparing adverse effects and myelographic quality

    International Nuclear Information System (INIS)

    In a blind clinical trial, adverse effects after iohexol and iopamidol myelography were evaluated in 151 dogs. Eighty-one dogs were given iohexol (240 mgI/ml) and 70 dogs were given iopamidol (200 mgI/ml) by pre-determined assignment. Each dog was evaluated postmyelographically for seizures, hyperthermia, prolonged recovery from anesthesia and intensification of pre-existing neural signs. Myelographic quality was evaluated with a subjective scoring method. In comparing iohexol and iopamidol groups, there was not a statistically significant difference in the incidence of adverse effects or in myelographic quality. Iopamidol and iohexol appeared to be equally efficacious for routine canine myelography

    ABSTRACT Much as an increase in the use of psychotropic drugs is observed in children and adolescents over the last decade, the endocrine and metabolic side effects of these drugs can limit their use. Atypical antipsychotics can cause many side effects, which are not suitable for the developmental periods of children and adolescents, such as those related with thyroid, blood sugar, level of sex hormones, growth rate and bone metabolism. Children are under a more serious risk regarding the wei...

    Adults’ intentionality judgments regarding an action are influenced by their moral evaluation of this action. This is clearly indicated in the so-called side-effect effect: when told about an action (e.g. implementing a business plan) with an intended primary effect (e.g. raise profits) and a foreseen side effect (e.g. harming/helping the environment), subjects tend to interpret the bringing about of the side effect more often as intentional when it is negative (harming the environment) than when it is positive (helping the environment). From a cognitive point of view, it is unclear whether the side-effect effect is driven by the moral status of the side effects specifically, or rather more generally by its normative status. And from a developmental point of view, little is known about the ontogenetic origins of the effect. The present study therefore explored the cognitive foundations and the ontogenetic origins of the side-effect effect by testing 4-to 5-year-old children with scenarios in which a side effect was in accordance with/violated a norm. Crucially, the status of the norm was varied to be conventional or moral. Children rated the bringing about of side-effects as more intentional when it broke a norm than when it accorded with a norm irrespective of the type of norm. The side-effect effect is thus an early-developing, more general and pervasive phenomenon, not restricted to morally relevant side effects. PMID:26218422

  16. Pretreatment Predictors of Adverse Radiation Effects After Radiosurgery for Arteriovenous Malformation

    International Nuclear Information System (INIS)

    Purpose: To identify vascular and dosimetric predictors of symptomatic T2 signal change and adverse radiation effects after radiosurgery for arteriovenous malformation, in order to define and validate preexisting risk models. Methods and Materials: A total of 125 patients with arteriovenous malformations (AVM) were treated at our institution between 2005 and 2009. Eighty-five patients have at least 12 months of clinical and radiological follow-up. Any new-onset headaches, new or worsening seizures, or neurological deficit were considered adverse events. Follow-up magnetic resonance images were assessed for new onset T2 signal change and the volume calculated. Pretreatment characteristics and dosimetric variables were analyzed to identify predictors of adverse radiation effects. Results: There were 19 children and 66 adults in the study cohort, with a mean age of 34 (range 6–74). Twenty-three (27%) patients suffered adverse radiation effects (ARE), 9 patients with permanent neurological deficit (10.6%). Of these, 5 developed fixed visual field deficits. Target volume and 12 Gy volume were the most significant predictors of adverse radiation effects on univariate analysis (p 3, above which the rate of ARE increased dramatically. Multivariate analysis target volume and the absence of prior hemorrhage are the only significant predictors of ARE. The volume of T2 signal change correlates to ARE, but only target volume is predictive of a higher volume of T2 signal change. Conclusions: Target volume and the absence of prior hemorrhage is the most accurate predictor of adverse radiation effects and complications after radiosurgery for AVMs. A high percentage of permanent visual field defects in this series suggest the optic radiation is a critical radiosensitive structure.

    2008-01-01

    Full Text Available In addition to their therapeutic effects on malignant cells, cytotoxic agents have the potential of causing destruction of healthy, normal cells. Extravasation of the drug can produce extensive necrosis of the skin and subcutaneous tissue. Management of these extravasational effects differs from one centre to another and prevention is usually strongly emphasized. We analyzed our management of 12 patients referred to us over five years with extravasation of cytotoxic drugs and reviewed the literature for different approaches with regard to prophylaxis and management of extravasational effects. Materials and Methods: This study was done in the department of plastic surgery of a medical college. Five years of retrospective data were studied of patients referred to our department with extravasation of cytotoxic drugs. Results: We managed 12 cases referred to our department with extravasation of cytotoxic drugs. Mitomycin C was used in seven cases (58.33%, vincristine in two cases (16.66%, 5-Florouracil in another two cases while doxorubicin was responsible for extravasational side effects in one case (8.33%. The size of necrosis ranged from 3.75 cm 2 to 25 cm 2 with average size of 9.6 cm 2 . In terms of the area involved, the dorsum of the hand was involved in five cases (41.66%, the wrist in another five cases (41.66%, and the cubital fossa in the remaining two cases (16.66%. All cases were treated with daily debridement of necrotic tissue, saline dressing, and split skin grafting. Conclusion: Extravasation of cytotoxic drugs further increases the suffering of cancer patients. This catastrophe can only be avoided by vigilance and immediate application of antidotes. Once the local toxicity of the drugs takes effect, morbidity is unavoidable

    Full Text Available Purpose: To evaluate whether transformation of the naso-lacrimal passage as happens after dacryocystorhinostomy (DCR operation has any effect on the systemic adverse effects of topically administered timolol maleate. Materials and Methods: Fifty otherwise healthy adult patients without any prior history of cardiac or pulmonary problems scheduled for elective DCR surgery received a drop of timolol maleate 0.5% on the healthy eye. This eye served as a control. Six weeks after successful DCR surgery, the operated eye received the same medication. Parameters compared included intraocular pressure (IOP, pulse rate, blood pressure and forced expiratory volume in the first second (FEV1 findings. Observations: Post DCR patients showed an increased incidence of reduced pulse rate and FEV1. Conclusion: Timolol maleate ophthalmic preparation should be used with caution in post-DCR patients.

  19. The Adverse Events and Hemodynamic Effects of Adenosine-Based Cardiac MRI

    International Nuclear Information System (INIS)

    We wanted to prospectively assess the adverse events and hemodynamic effects associated with an intravenous adenosine infusion in patients with suspected or known coronary artery disease and who were undergoing cardiac MRI. One hundred and sixty-eight patients (64 ± 9 years) received adenosine (140 μg/kg/min) during cardiac MRI. Before and during the administration, the heart rate, systemic blood pressure, and oxygen saturation were monitored using a MRI-compatible system. We documented any signs and symptoms of potential adverse events. In total, 47 out of 168 patients (28%) experienced adverse effects, which were mostly mild or moderate. In 13 patients (8%), the adenosine infusion was discontinued due to intolerable dyspnea or chest pain. No high grade atrioventricular block, bronchospasm or other life-threatening adverse events occurred. The hemodynamic measurements showed a significant increase in the heart rate during adenosine infusion (69.3 ± 11.7 versus 82.4 ± 13.0 beats/min, respectively; p < 0.001). A significant but clinically irrelevant increase in oxygen saturation occurred during adenosine infusion (96 ± 1.9% versus 97 ± 1.3%, respectively; p < 0.001). The blood pressure did not significantly change during adenosine infusion (systolic: 142.8 ± 24.0 versus 140.9 ± 25.7 mmHg; diastolic: 80.2 ± 12.5 mmHg versus 78.9 ± 15.6, respectively). This study confirms the safety of adenosine infusion during cardiac MRI. A considerable proportion of all patients will experience minor adverse effects and some patients will not tolerate adenosine infusion. However, all adverse events can be successfully managed by a radiologist. The increased heart rate during adenosine infusion highlights the need to individually adjust the settings according to the patient, e.g., the number of slices of myocardial perfusion imaging.

    Full Text Available Abstract Background Epidermal growth factor receptor inhibitors are widely prescribed anticancer drugs. Patients treated commonly develop dermatologic adverse drugs reactions, but rarely they are involved in systematic evaluation of their quality of life. This monocentric cross sectional study is carried out to assess quality of life in colon cancer patients experienced skin side effects due to anti epidermal growth factor receptor inhibitors therapy. Methods Consecutive patients with skin side effects to therapy treated at Fondazione Poliambulanza were enrolled in this study. Quality of life was evaluated with the Italian validated version of Skindex-29 questionnaire, exploring three dimensions: symptoms, emotional, and physical functioning. Skindex-29 was administered one time between the eighth and the twelfth week of the treatment. Results Forty-five consecutive patients, mainly with metastatic colon cancer (29 female, 16 male, with an average age of 59.31 years (ranging from 34-78 were included in the study and analyzed. Patients showed a great impact of skin side effects on symptoms (mean 43, followed by emotional (mean 30, and functioning (mean 26 scales. In general women, the 55-65 age class, and patients with partial remission reported the worst quality of life. Conclusions Epidermal growth factor receptor inhibitors' skin side effects have an important impact on quality of life in advanced colon cancer patients; symptoms scale is the most effect respect to emotional and functioning scales.

  2. Testing programs related to potential adverse flow effects in nuclear power plants

    International Nuclear Information System (INIS)

    Potential adverse flow effects on nuclear power plant Structures, Systems and Components (SSCs), can result from various causes. For example, reactor vessel and main steam system piping and components (including the steam dryer, safety relief and power-operated valves, and pipe supports) in BWR nuclear power plants can be damaged by pressure fluctuations and vibration resulting from acoustic resonances occurring in the main steam system or reactor vessel. The acoustic resonance phenomenon can also occur in pressurized water reactor (PWR) nuclear power plants with resulting damage to plant piping and components. Sampling probes in feedwater and condensate systems in nuclear power plants are also susceptible to adverse flow effects. The NRC staff reviews the evaluation performed by applicants for the construction and operation of nuclear power plants under 10 CFR Part 50 or Part 52 of the potential for adverse flow effects on plant SSCs. This proposed paper will discuss the various aspects of the programs established by applicants and licensees for monitoring plant data to verify that adverse flow effects are not occurring. These aspects of the test programs include the following: conducting walk-downs, and inspecting components during power ascension and operation at full licensed power conditions, dynamic response analysis of reactor internals under operational flow transients and steady-state conditions; preoperational flow-induced vibration testing of reactor internals; correlation of the test results with the analytical results.

    The purpose of this study was to examine the late adverse effects of childhood hematological disorders treated with chemotherapy and radiotherapy including whole cranial irradiation at Sapporo Medical University Hospital. Twenty-eight patients were treated with chemotherapy and 18-24 Gy of prophylactic cranial irradiation (PCI) for acute lymphoblastic leukemia (ALL), and 14 patients were treated with 3-12.8 Gy of total body irradiation (TBI) and bone marrow transplantation (BMT) for ALL, acute myelogenous leukemia (AML), chronic myelogenous leukemia (CML), myelodysplastic syndrome (MDS), malignant lymphoma, and aplastic anemia (AA). Age at diagnosis ranged from 2 to 15 years old, and 28 were males and 14 were females. All patients were disease-free more than 2 years after diagnosis. Of 42 patients, 4 patients had decreased height (less than -2 S.D.), 3 patients required hormone replacement therapy, 2 patients had mental retardation, 3 patients had leukoencephalopathy, and 1 patient had a second malignancy. Except for the cases of decreased height, 3 of 7 late adverse effects were occurred in patients who had relapse of disease, and the risk of the adverse effects seemed to be higher for those patients whose doses of PCI were 22 Gy or more, or who received an additional craniospinal irradiation due to relapse of disease, and 18 Gy of PCI did not increase the risk of adverse effects.

  7. Adverse effects in coronary angiography: a comparative study of different temperature contrast medium

    International Nuclear Information System (INIS)

    Objective: To investigate the correlation between different temperature contrast medium and the occurrence of adverse effects, including the chest discomfort, the changes of heart rate, ST segment and T wave, the operating time and the used dosage of contrast medium, in performing coronary angiography. Methods: According to the contrast medium temperature used in coronary angiography, the patients were randomly divided into two groups: room temperature group (n=521) and warm temperature group (n=522). The contrast medium used in warm temperature group was bathed in 37 ℃ water for 60 minutes when the coronary angiography was carried out. The T Wave amplitude changes ≥ 0.01 mv, ST segment depression ≥ 0.05 mv, changes in heart rate ≥ 10 times/min were brought into the positive accounting. The occurrence of adverse effects, such as palpitation, chest distress and pectoralgia, the operative time and the used dosage of contrast medium were recorded. The results were analyzed and compared between the two groups. Results: Statistically significant differences in the changes of heart rate, ST segment deviation, T wave change and operating time existed between the two groups (P<0.05). And the difference in the occurrence of adverse effects between the two groups was also statistically significant (P<0.05). Conclusion: When performing coronary angiography, warming of the contrast medium with water bath is greatly conducive to the prevention of cardiac adverse effects. (authors)

  11. Crossings as a side effect of dependency lengths

    CERN Document Server

    Ferrer-i-Cancho, Ramon

    2015-01-01

    The syntactic structure of sentences exhibits a striking regularity: dependencies tend to not cross when drawn above the sentence. Here we investigate two competing hypotheses for the origins of non-crossing dependencies. The traditional hypothesis is that the low frequency of dependency crossings arises from an independent principle of syntax that reduces crossings practically to zero. An alternative to this view is the hypothesis that crossings are a side effect of dependency lengths. According to this view, sentences with shorter dependency lengths should tend to have fewer crossings. We recast the traditional view as a null hypothesis where one of the variables, i.e. the number of crossings, is mean independent of the other, i.e. the sum of dependency lengths. The alternative view is then a positive correlation between these two variables. In spite of the rough estimation of dependency crossings that this sum provides, we are able to reject the traditional view in the majority of languages considered. The...

  12. Treatment of neuroblastoma with metaiodobenzylguanidine: results and side effects

    International Nuclear Information System (INIS)

    Between April 1984 and December 1985 we treated ten children suffering from neuroblastoma in a total of 25 metaiodobenzylguanidine (MIBG) courses. Five had had a relapse of neuroblastoma stage III or IV, three had never achieved a remission in spite of intensive chemotherapy, and two were treated with an unstable remission. The children were each administered from 1 to 5 courses with a dosage per course of between 1295 and 9065 MBq. The sum of the single doses during the whole course of therapy ranged between 3145 and 21,904 MBq per child. Five of five children suffering from bone pain and fever became free of complaints during the first three treatment days. Six of eight children with manifest tumor at onset of therapy responded well to the treatment: response extended from transitory decrease in elevated catecholamine levels in serum and urine to complete disappearance of large abdominal tumor masses. We also observed a decrease in bone marrow involvement and a stabilization of osteolytic lesions. Seven of these eight children died in spite of a good response from 55 to 350 days after the first MIBG treatment course. The only side effect we witnessed was a reversible bone marrow depression. In three children we combined the MIBG therapy with bone marrow transplantation

    Drug-induced renal injury represents a frequent clinical entity. The most common drugs associated with acute tubular necrosis are aminoglycosides, amphotericin B, radiocontrast agents, and cyclosporine, but no data exist about the potential renal toxicity due to anthelmintics administration. Anthelmintics are commonly considered quite safe agents, and side effects such as gastrointestinal, neurologic, hematologic, or hepatic injury have been only rarely described. We report a 4-year-old boy with persistent massive proteinuria without any other symptoms/signs suggesting nephrotic syndrome (NS). The only relevant anamnestic data was the administration of pyrantel pamoate due to oxyuriasis 7 days before the proteinuria development. The patient was affected by NS diagnosed 6 months before and treated with a 12-week course of corticosteroids. During follow-up, carried out at 3 and 6 months after discharge, he did not show further episodes of proteinuria, and no clinical symptoms/signs suggesting a relapse of NS were ever detected. Considering that the proteinuria observed in our patient spontaneously disappeared after 10 days without any treatment, apart from the interruption of the anthelmintic therapy, we would like to alert pediatricians about the possible occurrence of anthelmintics-related renal complications especially among predisposed patients and to perform a watchful waiting not considering the presence of even massive proteinuria as a certain sign of NS relapse.

    In this article, we provide information on patient-reported side effects from a cross-section of real-world patients. Specifically, data on side effects were tabulated for patients taking one of the following attention deficit hyperactivity disorder medications: amphetamine and dextroamphetamine; atomoxetine; dexmethylphenidate; isdexamfetamine; and methylphenidate. Forty-eight percent of the approximately 325 patients surveyed reported having experienced a side effect as a result of taking an attention deficit hyperactivity disorder medication. Most common side effects mentioned included loss of appetite, sleep problems, and mood disturbances. Only 21 percent of side effects were considered very bothersome or extremely bothersome. Regardless of how bothersome the side effects were, only 20 percent of patients mentioned the side effects to their prescribing physicians. PMID:20508803

    This cross-sectional study compared the effects of treatment with atypical antipsychotic drugs on quality of life (QoL) and side effects in 218 patients with schizophrenia attending the ambulatory services of psychiatric in Rio Grande do Norte, Brazil. Socio-economic variables were compared. The five-dimension EuroQoL (EQ-5D) was used to evaluate QoL, and side effects were assessed using the Udvalg for Kliniske Undersøgelser (UKU) Side Effect Rating Scale and the Simpson-Angus Scale. Data were analysed using the χ (2) test and Student's t test, with a significance level of 5 %. Average monthly household incomes in the medication groups were 1.1-2.1 minimum wages ($339-$678). UKU Scale scores showed significant differences in side effects, mainly, clozapine, quetiapine and ziprasidone (p < 0.05). EQ-5D scores showed that all drugs except olanzapine significantly impacted mobility (p < 0.05), and proportions of individuals reporting problems in other dimensions were high: 63.6 % of clozapine users reported mobility problems, 63.7 and 56.3 % of clozapine and ziprasidone users, respectively, had difficulties with usual activities, 68.8 and 54.5 % of ziprasidone and clozapine users, respectively, experienced pain and/or discomfort, and 72.8 % of clozapine users reported anxiety and/or depression. Psychiatric, neurological, and autonomous adverse effects, as well as other side effects, were prevalent in users of atypical antipsychotic drugs, especially clozapine and ziprasidone. Olanzapine had the least side effects. QoL was impacted by side effects and economic conditions in all groups. Thus, the effects of these antipsychotic agents appear to have been masked by aggravating social and economic situations. PMID:24789610

    A new statistical methodology is developed for the analysis of spontaneous adverse event (AE) reports from post-marketing drug surveillance data. The method involves both empirical Bayes (EB) and fully Bayes estimation of rate multipliers for each drug within a class of drugs, for a particular AE, based on a mixed-effects Poisson regression model. Both parametric and semiparametric models for the random-effect distribution are examined. The method is applied to data from Food and Drug Administration (FDA)'s Adverse Event Reporting System (AERS) on the relationship between antidepressants and suicide. We obtain point estimates and 95 per cent confidence (posterior) intervals for the rate multiplier for each drug (e.g. antidepressants), which can be used to determine whether a particular drug has an increased risk of association with a particular AE (e.g. suicide). Confidence (posterior) intervals that do not include 1.0 provide evidence for either significant protective or harmful associations of the drug and the adverse effect. We also examine EB, parametric Bayes, and semiparametric Bayes estimators of the rate multipliers and associated confidence (posterior) intervals. Results of our analysis of the FDA AERS data revealed that newer antidepressants are associated with lower rates of suicide adverse event reports compared with older antidepressants. We recommend improvements to the existing AERS system, which are likely to improve its public health value as an early warning system. PMID:18404622

  19. Adverse effects of the antimalaria drug, mefloquine: due to primary liver damage with secondary thyroid involvement?

    Full Text Available Abstract Background Mefloquine is a clinically important antimalaria drug, which is often not well tolerated. We critically reviewed 516 published case reports of mefloquine adverse effects, to clarify the phenomenology of the harms associated with mefloquine, and to make recommendations for safer prescribing. Presentation We postulate that many of the adverse effects of mefloquine are a post-hepatic syndrome caused by primary liver damage. In some users we believe that symptomatic thyroid disturbance occurs, either independently or as a secondary consequence of the hepatocellular injury. The mefloquine syndrome presents in a variety of ways including headache, gastrointestinal disturbances, nervousness, fatigue, disorders of sleep, mood, memory and concentration, and occasionally frank psychosis. Previous liver or thyroid disease, and concurrent insults to the liver (such as from alcohol, dehydration, an oral contraceptive pill, recreational drugs, and other liver-damaging drugs may be related to the development of severe or prolonged adverse reactions to mefloquine. Implications We believe that people with active liver or thyroid disease should not take mefloquine, whereas those with fully resolved neuropsychiatric illness may do so safely. Mefloquine users should avoid alcohol, recreational drugs, hormonal contraception and co-medications known to cause liver damage or thyroid damage. With these caveats, we believe that mefloquine may be safely prescribed in pregnancy, and also to occupational groups who carry out safety-critical tasks. Testing Mefloquine's adverse effects need to be investigated through a multicentre cohort study, with small controlled studies testing specific elements of the hypothesis.

    The role of the side channels in the continuous-variable quantum key distribution is studied. It is shown how the information leakage through a side channel from the trusted sender station increases the vulnerability of the protocols to the eavesdropping in the main quantum communication channel. Moreover, the untrusted noise infusion by an eavesdropper on the trusted receiving side breaks the security even for a purely attenuating main quantum channel. As a method to compensate for the effect of the side-channel leakage on the sender side, we suggest several types of manipulations on the side-channel input. It is shown that by applying the modulated coherent light on the input of the side channel that is optimally correlated to the modulation on the main signal and optionally introducing additional squeezing in the case of the squeezed-state protocol, the negative influence of the lossy side channel on the sender side can be completely removed. For the trusted receiving side, the method of optimal monitoring of the residual noise from the side-channel noise infusion is suggested and shown to be able to completely eliminate the presence of the noisy side channel. We therefore prove that the side-channel effects can be completely removed using feasible operations if the trusted parties access the respective parts of the side channels.

    The dopamine transporter locus (DAT1) has been studied as a risk factor for attention-deficit/hyperactivity disorder (ADHD) and in pharmacogenetic studies of stimulant response. Several prospective studies have reported an association between the homozygous 9 repeat allele of the DAT1 3' untranslated region (UTR) variable number tandem repeat (VNTR) (DAT1 3') and decreased efficacy of methylphenidate (MPH). We hypothesized that children with the 9/9 genotype would display higher rates of specific stimulant side effects. Data on adverse events and DAT1 3' genotypes were combined from two, double-blind, placebo-controlled, crossover studies of MPH conducted in child psychiatric outpatient clinics in Montreal and Washington, D.C. There were 177 participants, 5-16 years old (mean age = 8.99, standard deviation [SD] = 2), with ADHD. Parents completed the Stimulant Side Effect Scale (SERS) after a week of placebo and a week of MPH treatment. Principal components analysis of the SERS resulted in three factors: Emotionality, Somatic Complaints, and Over-focused. Children with the 9/9 genotype displayed higher scores on the Emotionality factor during placebo than children with the 9/10 and the 10/10 genotype, and their Emotionality scores increased further during MPH treatment (F[2,151] = 3.24, p side effects. Children with the 9/10 genotype displayed less severe stimulant side-effect ratings than either of the homozygous groups, who each displayed increased susceptibility to different types of adverse events. Preliminary evidence suggests that pharmacogenetic analysis using DAT1 variants shows promise for identifying individuals at increased or decreased risk for poor tolerability. PMID:19519258

  2. In vivo evaluation on the effects of HemoHIM in promoting anticancer activities and reducing the side-effects of anticancer drugs

    International Nuclear Information System (INIS)

    In this project, we aimed to obtain the preclinical in vivo evaluation data for the development of the herbal composition (HemoHIM) as the auxiliary agent for the anticancer treatment that can reduce the side-effects of anticancer drugs and enhance their anticancer activities. Firstly, in vitro studies showed that HemoHIM did not show any effects on the tumor cell growth inhibition by 2 anticancer drugs (cisplatin, 5-FU), which indicated that at least HemoHIM does not exert any adverse effects on the activities of anticancer drugs. Next, the in vivo studies with mice implanted with tumor cells(B16F0, LLC1) showed that HemoHIM partially enhanced the anticancer activities of drugs (cisplatin, 5-FU), and improved endogenous anticancer immune activities. Furthermore, in the same animal models, HemoHIM effectively reduced the side-effects of anticancer drugs (liver and renal toxicities by cisplatin, immune and hematopoietic disorders by 5-FU). These results collectively showed that HemoHIM can enhance the activities of anticancer drugs and reduce their side-effects in vitro and in vivo and HemoHIM does not exert any adverse effects on the efficacy of anticancer drugs. The results of this project can be utilized as the basic preclinical data for the development and approval of HemoHIM as the auxiliary agent for the anticancer treatment

    Full Text Available As a further step towards the modernization of acupuncture, the objective of this review was to figure out the frequency and severity of adverse complications and events in acupuncture treatment reported from 1980 to 2013 in China. All first-hand case reports of acupuncture-related complications and adverse events that could be identified in the scientific literature were reviewed and classified according to the type of complication and adverse event, circumstance of the event, and long-term patient outcome. The selected case reports were published between 1980 and 2013 in 3 databases. Relevant papers were collected and analyzed by 2 reviewers. Over the 33 years, 182 incidents were identified in 133 relevant papers. Internal organ, tissue, or nerve injury is the main complications of acupuncture especially for pneumothorax and central nervous system injury. Adverse effects also included syncope, infections, hemorrhage, allergy, burn, aphonia, hysteria, cough, thirst, fever, somnolence, and broken needles. Qualifying training of acupuncturists should be systemized and the clinical acupuncture operations should be standardized in order to effectively prevent the occurrence of acupuncture accidents, enhance the influence of acupuncture, and further popularize acupuncture to the rest of the world.

  5. Effects of utility demand-side management programs on uncertainty

    International Nuclear Information System (INIS)

    Electric utilities face a variety of uncertainties that complicate their long-term resource planning. These uncertainties include future economic and load growths, fuel prices, environmental and economic regulations, performance of existing power plants, cost and availability of purchased power, and the costs and performance of new demand and supply resources. As utilities increasingly turn to demand-side management (DSM) programs to provide resources, it becomes more important to analyze the interactions between these programs and the uncertainties facing utilities. This paper uses a dynamic planning model to quantify the uncertainty effects of supply-only vs DSM + supply resource portfolios. The analysis considers four sets of uncertainties: economic growth, fuel prices, the costs to build new power plants, and the costs to operate DSM programs. The two types of portfolios are tested against these four sets of uncertainties for the period 1990 to 2010. Sensitivity, scenario, and worst-case analysis methods are used. The sensitivity analyses show that the DSM + supply resource portfolio is less sensitive to unanticipated changes in economic growth, fuel prices, and power-plant construction costs than is the supply-only portfolio. The supply-only resource mix is better only with respect to uncertainties about the costs of DSM programs. The base-case analysis shows that including DSM programs in the utility's resource portfolio reduces the net present value of revenue requirements (NPV-RR) by 490 million dollars. The scenario-analysis results show an additional 30 million dollars (6%) in benefits associated with reduction in these uncertainties. In the worst-case analysis, the DSM + supply portfolio again reduces the cost penalty associated with guessing wrong for both cases, when the utility plans for high needs and learns it has low needs and vice versa. 20 refs

    To provide an adequate level of protection for humans from exposure to radio-frequency (RF) electromagnetic fields (EMF) and to assure that any adverse health effects are avoided. The basic restrictions in terms of the specific energy absorption rate (SAR) were prescribed by IEEE and ICNIRP. An example of a therapeutic application of non-ionizing EMF is hyperthermia (HT), in which intense RF energy is focused at a target region. Deep HT in the head and neck (H&N) region involves inducing energy at 434 MHz for 60 min on target. Still, stray exposure of the brain is considerable, but to date only very limited side-effects were observed. The objective of this study is to investigate the stringency of the current basic restrictions by relating the induced EM dose in the brain of patients treated with deep head and neck (H&N) HT to the scored acute health effects. We performed a simulation study to calculate the induced peak 10 g spatial-averaged SAR (psSAR10g) in the brains of 16 selected H&N patients who received the highest SAR exposure in the brain, i.e. who had the minimum brain-target distance and received high forwarded power during treatment. The results show that the maximum induced SAR in the brain of the patients can exceed the current basic restrictions (IEEE and ICNIRP) on psSAR10g for occupational environments by 14 times. Even considering the high local SAR in the brain, evaluation of acute effects by the common toxicity criteria (CTC) scores revealed no indication of a serious acute neurological effect. In addition, this study provides pioneering quantitative human data on the association between maximum brain SAR level and acute adverse effects when brains are exposed to prolonged RF EMF.

    As a society we are increasingly concerned about our physical appearance. For example, as much as 24% of people in developed countries admittedly exercise to improve their performance. Professional sportsmen and amateurs alike are in a constant search for new means that will enable them better sport results in shorter time. Among those means, a prominent place belongs to dietary supplements. However, the producers often advertise products whose use in sports is neither scientifically founded nor safe. This brings on an irrational use of herbal supplements which sometimes leads to unwanted side effects, but is more often of little use. Thus, the aim of this review will be to systematically evaluate some of the herbal supplements that are used as adaptogenic and ergogenic aids in sport. The review will include available data on Rhodiola rosea, Withania somnifera, Schisandra chinensis, Tribulus terrestris, Vitis vinifera, Citrus aurantium, and others. Their effects, active ingredients as well as possible adverse effects will be discussed with special focus on clinical studies. PMID:23574283

    Full Text Available Abstract Background Multi-item adverse drug event (ADE associations are associations relating multiple drugs to possibly multiple adverse events. The current standard in pharmacovigilance is bivariate association analysis, where each single drug-adverse effect combination is studied separately. The importance and difficulty in the detection of multi-item ADE associations was noted in several prominent pharmacovigilance studies. In this paper we examine the application of a well established data mining method known as association rule mining, which we tailored to the above problem, and demonstrate its value. The method was applied to the FDAs spontaneous adverse event reporting system (AERS with minimal restrictions and expectations on its output, an experiment that has not been previously done on the scale and generality proposed in this work. Results Based on a set of 162,744 reports of suspected ADEs reported to AERS and published in the year 2008, our method identified 1167 multi-item ADE associations. A taxonomy that characterizes the associations was developed based on a representative sample. A significant number (67% of the total of potential multi-item ADE associations identified were characterized and clinically validated by a domain expert as previously recognized ADE associations. Several potentially novel ADEs were also identified. A smaller proportion (4% of associations were characterized and validated as known drug-drug interactions. Conclusions Our findings demonstrate that multi-item ADEs are present and can be extracted from the FDA’s adverse effect reporting system using our methodology, suggesting that our method is a valid approach for the initial identification of multi-item ADEs. The study also revealed several limitations and challenges that can be attributed to both the method and quality of data.

    Full Text Available Exposure to childhood adversities (CA is associated with subsequent alterations in regional brain grey matter volume (GMV. Prior studies have focused mainly on severe neglect and maltreatment. The aim of this study was to determine in currently healthy adolescents if exposure to more common forms of CA results in reduced GMV. Effects on brain structure were investigated using voxel-based morphometry in a cross-sectional study of youth recruited from a population-based longitudinal cohort. 58 participants (mean age = 18.4 with (n = 27 or without (n = 31 CA exposure measured retrospectively from maternal interview were included in the study. Measures of recent negative life events (RNLE recorded at 14 and 17 years, current depressive symptoms, gender, participant/parental psychiatric history, current family functioning perception and 5-HTTLPR genotype were covariates in analyses. A multivariate analysis of adversities demonstrated a general association with a widespread distributed neural network consisting of cortical midline, lateral frontal, temporal, limbic, and cerebellar regions. Univariate analyses showed more specific associations between adversity measures and regional GMV: CA specifically demonstrated reduced vermis GMV and past psychiatric history with reduced medial temporal lobe volume. In contrast RNLE aged 14 was associated with increased lateral cerebellar and anterior cingulate GMV. We conclude that exposure to moderate levels of childhood adversities occurring during childhood and early adolescence exerts effects on the developing adolescent brain. Reducing exposure to adverse social environments during early life may optimize typical brain development and reduce subsequent mental health risks in adult life.

    Students with attention-deficit/hyperactivity disorder (ADHD) experience significant academic difficulties that can lead to numerous negative academic consequences. With a focus on adverse academic outcomes, this study seeks to disentangle variance attributable to ADHD from variance attributable to salient personal and contextual covariates. Responses from 136 students with ADHD and 3,779 non-ADHD peers from 9 high schools were analyzed using logistic regression. Dependent measures included academic failure, grade repetition, school refusal, changing classes and school, school exclusion, and schoolwork noncompletion. Covariates comprised personal (e.g., sociodemographics, personality, prior achievement, specific learning disabilities, motivation) and contextual (e.g., school size, school socioeconomic status, school average achievement) factors. Findings indicated that, after accounting for personal and contextual covariates, ADHD explained significant variance in numerous adversities (schoolwork noncompletion, school suspension, school expulsion, changing schools, grade repetition). Thus, beyond the effects of numerous personal and contextual covariates, ADHD has a distinct presence in students' academic adversity. Also interesting, after accounting for other personal and contextual factors, was academic adversity with which ADHD was not associated. Findings provide direction for educational intervention targeting ADHD and associated factors found to be significant in the study. PMID:24820011

    Full Text Available Poly(epsilon-caprolactone (PCL nanocapsules have been used as a carrier system for the herbicide atrazine, which is commonly applied to maize. We demonstrated previously that these atrazine containing polymeric nanocapsules were ten-fold more effective in the control of mustard plants (a target species, as compared to a commercial atrazine formulation. Since atrazine can have adverse effects on non-target crops, here we analyzed the effect of encapsulated atrazine on growth, physiological and oxidative stress parameters of soil-grown maize plants (Zea mays L.. One day after the post-emergence treatment with PCL nanocapsules containing atrazine (1 mg mL-1, maize plants presented 15 and 21 % decreases in maximum quantum yield of photosystem II and in net CO2 assimilation rate, respectively, as compared to water-sprayed plants. The same treatment led to a 1.8-fold increase in leaf lipid peroxidation in comparison with control plants. However, all of these parameters were unaffected four and eight days after the application of encapsulated atrazine. These results suggested that the negative effects of atrazine were transient, probably due to the ability of maize plants to detoxify the herbicide. When encapsulated atrazine was applied at a ten-fold lower concentration (0.1 mg mL-1, a dosage that is still effective for weed control, no effects were detected even shortly after application. Regardless of the herbicide concentration, neither pre- nor post-emergence treatment with the PCL nanocapsules carrying atrazine resulted in the development of any macroscopic symptoms in maize leaves, and there were no impacts on shoot growth. Additionally, no effects were observed when plants were sprayed with PCL nanocapsules without atrazine. Overall, these results suggested that the use of PCL nanocapsules containing atrazine did not lead to persistent side effects in maize plants, and that the technique could offer a safe tool for weed control without affecting

    Opioid effects are potentiated by cannabinoid agonists including anandamide, an endocannabinoid. Inter-individual variability in responses to opioids is a major clinical problem. Multiple deaths and anoxic brain injuries occur every year because of opioid-induced respiratory depression (RD) in surgical patients and drug abusers of opioids and cannabinoids. This study aimed to determine specific associations between genetic variants of fatty acid amide hydrolase (FAAH) and postoperative central opioid adverse effects in children undergoing tonsillectomy. This is a prospective genotype-blinded observational study in which 259 healthy children between 6 and 15 years of age who received standard perioperative care with a standard anesthetic and an intraoperative dose of morphine were enrolled. Associations between frequent polymorphisms of FAAH and central postoperative opioid adverse effects including, RD, postoperative nausea and vomiting (PONV) and prolonged stay in Post Anesthesia Recovery Room (postoperative anesthesia care unit, PACU) due to RD and PONV were analyzed. Five specific FAAH single nucleotide polymorphisms (SNPs) had significant associations with more than twofold increased risk for refractory PONV (adjusted PPACU stay in white children undergoing tonsillectomy. The FAAH SNP, rs324420, is a missense mutation with altered FAAH function and it is linked with other FAAH SNPs associated with PONV and RD in our cohort; association between PONV and rs324420 was confirmed in our extended cohort with additional 66 white children. Specific FAAH polymorphisms are associated with refractory PONV, opioid-related RD, and prolonged PACU stay due to opioid adverse effects in white children undergoing tonsillectomy. PMID:25558980

  2. Development of STI/AOT optimization methodology and an application to the AFWPs with adverse effects

    International Nuclear Information System (INIS)

    Adverse effects caused by the surveillance test for the components of nuclear power plant involve plant transients, unnecessary wear, burden on licensee's time, and the radiation exposure to personnel along with the characteristics of each component. The optimization methodology of STI and AOT has been developed and applied to AFWPs of a reference plant. The approach proposed in this paper consists of the results in minimal mean unavailability of the two-out-of-four system with adverse effects are analytically calculated for the example system. The surveillance testing strategy are given by the sequential test, the staggered test and the train staggered test, which is a mixed test scheme. In the system level, the sensitivity analyses for the STI and AOT, are performed for the measure of the system unavailability of the top event in the fault tree developed for the example system. This methodology may contribute to establishing the basis for the risk-based regulations. (author)

    Many adverse drug effects (ADEs) can be attributed to drug interactions. Spontaneous reporting systems (SRS) provide a rich opportunity to detect novel post-marketed drug interaction adverse effects (DIAEs), as they include populations not well represented in clinical trials. However, their identification in SRS is nontrivial. Most existing research have addressed the statistical issues used to test or verify DIAEs, but not their identification as part of a systematic large scale database-wide mining process as discussed in this work. This paper examines the application of a highly optimized and tailored implementation of the Apriori algorithm, as well as methods addressing data quality issues, to the identification of DIAEs in FDAs SRS.

    Full Text Available Interferons alpha and beta have been used worldwide for a few decades, altering the natural history of several severe diseases including hepatitis C, cancer and immune-mediated conditions such as multiple sclerosis. The adverse events profile of interferons is well established, but only isolated reports of ophthalmological complications of interferon therapy have been published. The objective of this study was to carry out a literature systematic review on the subject, bringing to light the need for careful ophthalmological monitoring of patients undergoing interferon treatment. Nearly 500 cases of ophthalmological complications related to interferon have been reported. The most frequent findings were soft exudates, hemorrhages and retina ischemia.

  10. Predicting Nonauditory Adverse Radiation Effects Following Radiosurgery for Vestibular Schwannoma: A Volume and Dosimetric Analysis

    International Nuclear Information System (INIS)

    Purpose: To define clinical and dosimetric predictors of nonauditory adverse radiation effects after radiosurgery for vestibular schwannoma treated with a 12 Gy prescription dose. Methods: We retrospectively reviewed our experience of vestibular schwannoma patients treated between September 2005 and December 2009. Two hundred patients were treated at a 12 Gy prescription dose; 80 had complete clinical and radiological follow-up for at least 24 months (median, 28.5 months). All treatment plans were reviewed for target volume and dosimetry characteristics; gradient index; homogeneity index, defined as the maximum dose in the treatment volume divided by the prescription dose; conformity index; brainstem; and trigeminal nerve dose. All adverse radiation effects (ARE) were recorded. Because the intent of our study was to focus on the nonauditory adverse effects, hearing outcome was not evaluated in this study. Results: Twenty-seven (33.8%) patients developed ARE, 5 (6%) developed hydrocephalus, 10 (12.5%) reported new ataxia, 17 (21%) developed trigeminal dysfunction, 3 (3.75%) had facial weakness, and 1 patient developed hemifacial spasm. The development of edema within the pons was significantly associated with ARE (p = 0.001). On multivariate analysis, only target volume is a significant predictor of ARE (p = 0.001). There is a target volume threshold of 5 cm3, above which ARE are more likely. The treatment plan dosimetric characteristics are not associated with ARE, although the maximum dose to the 5th nerve is a significant predictor of trigeminal dysfunction, with a threshold of 9 Gy. The overall 2-year tumor control rate was 96%. Conclusions: Target volume is the most important predictor of adverse radiation effects, and we identified the significant treatment volume threshold to be 5 cm3. We also established through our series that the maximum tolerable dose to the 5th nerve is 9 Gy.

MATERIAL AND METHOD: The population of this descriptive- cross-sectional study is 15-49 age, married women who recruited in the number 15 health-center region. The sample consisted of 183 women who were selected with systematic sampling method. A questionnaire designed with researcher based on literature which was 30 questions include fertility characteristics, VD practice and adverse health effects was used to collect data. The data were collected by the researcher with home visiting between April-May 2005. Descriptive statistics and X² test were used to analysis data. RESULTS: The mean age of women in the study group is 33.5±7.86, 87. 4 % has primary school education, 68.3 % middle income, 54.6 % practice VD. The mean year of VD practice is 12.9±8.8 and 65.1 % douche at least once a week. The reasons of the women’s VD practices are religious practice (45.4 %, cleaning (41.5% and preventing pregnancy(13.1% and, 68.9 % of women don’t know harmfull efects of VD. There was no difference between history of sterility, extopic pregnancy, abortus, low birth weigh, symptoms of genito-urinary infection and its frequency and VD in the X² test. There was a difference between contraceptive method used and VD. CONCLUSION: Sterility, extopic pregnancy, abortus, low birth weigh, symptoms of genito-urinary infection and its frequency were not related to VD. We suggest that the women have been educated about adverse health effects of VD and analytic researches may be planned for causal relationship between adverse health effects and VD.

    Full Text Available This study aimed at evaluating the incidence of adverse effects leading to treatment discontinuation of antihypertensive drugs within the same therapeutic class. Individual medical records were searched to identify those hypertensive patients who had been commenced on antihypertensive therapy during a 24-month period and who had subsequently for a reason(s discontinued the therapy. The results showed variation in discontinuation rates for drugs within same class, and that might be related to the relative frequency of specific adverse effects. Cough was the reason cited for discontinuation of angiotensin converting enzyme inhibitors, with linosopril appearing to be better tolerated than captopril (39% vs 48% ; peripheral oedema with calcium channel blockers, with amlodipine appearing to be better tolerated than nifedipine (29% vs 38% and bradycardia with beta adrenergic receptor blockers, with propranolol better tolerated than atenolol (0% vs 48%. Diuretics showed the lowest discontinuation rate (3.3% mainly due to hypokalemia, with thiazide better tolerated than frusemide (11% vs 43%. Prescribers should verify their use of antihypertensive drugs to ensure that they prescribe drugs with lower adverse effect rates, in order that patients with hypertension continue using the medication in the long term, thereby reducing the risk of developing cardiovascular complications associated with uncontrolled blood pressure.

    Full Text Available ABSTRACT Much as an increase in the use of psychotropic drugs is observed in children and adolescents over the last decade, the endocrine and metabolic side effects of these drugs can limit their use. Atypical antipsychotics can cause many side effects, which are not suitable for the developmental periods of children and adolescents, such as those related with thyroid, blood sugar, level of sex hormones, growth rate and bone metabolism. Children are under a more serious risk regarding the weight increasing effects of atypical antipsychotics and weight gain that is not proportionate with age is especially important due to the association between glucose or lipid abnormalities and cardiovascular mortality. Aripiprazole and ziprasidone are the least risky antipsychotic drugs when it comes to metabolic side affects. The antipsychotic drug that is associated with weight increase and diabetes in children and adolescents most is olanzapine. Even though there are no comparative long-term data concerning children, it is suggested by the currently available information that metabolic side effects including dyslipidemia and impaired glucose tolerance are at an alarming level when it comes to long-term treatment with antipsychotics. The most risky agents in terms of hyperglycemia and glucosuria development are olanzapine and clozapine. Use of risperidone and haloperidol should be undertaken with caution since it may bring about the risk of hyperprolactinemia. Among the antidepressants associated with weight loss and suppression of appetite are selective serotonin reuptake inhibitors, bupropion and venlafaxine. Thyroid functions can be affected by lithium, carbamazepine and valproate treatments. It is reported that the side effect most frequently associated with valproate is weight increase. The relationship between valproate treatment and the development of hyperandrogenism and polycystic ovary syndrome in young women should also be kept in mind. [TAF Prev

    The treatment of various hair disorders has become a central focus of good dermatologic patient care as it affects men and women all over the world. For many inflammatory-based scalp diseases, glucocorticoids are an essential part of treatment, even though they are known to cause systemic as well as local adverse effects when applied topically. Therefore, efficient targeting and avoidance of these side effects are of utmost importance. Optimizing the balance between drug release, interfollicular permeation, and follicular uptake may allow minimizing these adverse events and simultaneously improve drug delivery, given that one succeeds in targeting a sustained release formulation to the hair follicle. To test this hypothesis, three types of polymeric nanocarriers (nanospheres, nanocapsules, lipid-core nanocapsules) for the potent glucocorticoid clobetasol propionate (CP) were prepared. They all exhibited a sustained release of drug, as was desired. The particles were formulated as a dispersion and hydrogel and (partially) labeled with Rhodamin B for quantification purposes. Follicular uptake was investigated using the Differential Stripping method and was found highest for nanocapsules in dispersion after application of massage. Moreover, the active ingredient (CP) as well as the nanocarrier (Rhodamin B labeled polymer) recovered in the hair follicle were measured simultaneously, revealing an equivalent uptake of both. In contrast, only negligible amounts of CP could be detected in the hair follicle when applied as free drug in solution or hydrogel, regardless of any massage. Skin permeation experiments using heat-separated human epidermis mounted in Franz Diffusion cells revealed equivalent reduced transdermal permeability for all nanocarriers in comparison to application of the free drug. Combining these results, nanocapsules formulated as an aqueous dispersion and applied by massage appeare to be a good candidate to maximize follicular targeting and minimize drug

    This paper exploits a unique ongoing experiment to analyze the effects of early rearing conditions on physical and mental health in a sample of rhesus monkeys (Macaca mulatta). We analyze the health records of 231 monkeys that were randomly allocated at birth across three rearing conditions: mother rearing, peer rearing, and surrogate peer rearing. We show that the lack of a secure attachment relationship in the early years engendered by adverse rearing conditions has detrimental long-term effects on health that are not compensated for by a normal social environment later in life.

    2013-04-01

    Full Text Available Background: Proton pump inhibitors (PPIs have provided important benefits in the management of gastroesophageal reflux disease (GERD, peptic ulcer disease and in the prevention of non steroidal antiinflammatory drugs and aspirin-related ulcer complications. PPIs are also the most commonly used medications for stress ulcer prophylaxis, despite little evidence to support their use in non-intensive care unit. Discussion: Considering the widespread use of PPIs, these agents’ overall safety profile is unquestionable. However, there is growing evidence that PPIs use may be associated with an increased risk of enteric infections, pneumonia, hip fractures, vitamin B12 deficiency. Overall, until now, none of these adverse effects have discouraged the PPIs treatment. Recently attention has been placed on a more important potential adverse effect of PPIs, their interaction with clopidogrel to which they are associated for the prophylaxis of gastrointestinal bleeding. Preliminary results of laboratory tests suggest that omeprazole reduces clopidogrel’s antiplatelet effect. The interaction seems to involve the competitive inhibition of the CYP2C19 isoenzyme. The effect appears to be clinically important, as some retrospective studies have shown an increase in adverse cardiovascular outcomes when PPIs and clopidogrel are used concomitantly. Some studies indicate that pantoprazole and esomeprazole are not associated with impaired response to clopidogrel. However, the available data for PPIs other than omeprazole do not allow definitive conclusions to be drawn about whether is a class effect. Conclusions: Specifically designed and randomized clinical studies are needed to define the interaction between PPIs and clopidogrel. Moreover, alternative treatment strategies with histamine- 2 receptor antagonists that are not dependent on cytochrome p450 2C19 should be tested in future studies.

    Full Text Available Patricia PoirierUniversity of Maine School of Nursing, Orono, ME, USAAbstract: It has been estimated that 50%–60% of patients diagnosed with cancer will receive radiation therapy at some point in their treatment. Although radiation therapy can play a significant role in the cure or control of cancer, and the palliation of symptoms, it also has side effects. Side effects of radiation therapy can interfere with patient quality of life and daily functioning. Severe side effects can lead to delays in treatment, potentially affecting the outcome of treatment. All patients receiving radiation therapy are at risk of fatigue and skin reactions in the area of the body being treated. Other side effects of radiation therapy are specific to the part of the body being treated. Radiation therapy to the head and neck area may cause oral mucositis, dryness, and nutritional deficiencies. Radiation therapy to the chest or lung area may lead to difficulty in swallowing and eating. Radiation therapy to the pelvis frequently causes diarrhea. There are many nursing interventions available to manage the side effects of treatment based on best available evidence and expert opinion. Nurses in all settings are essential in helping patients manage the side effects of treatment and maintain their quality of life. The purpose of this review is to provide nurses with evidence-based recommendations and suggestions for managing common acute side effects of radiation therapy.Keywords: evidence-based practice, radiation therapy, side effects, nursing management

    Full Text Available Introduction Hepatitis C virus infection is a slowly progressive chronic disease and the most common cause of chronic liver disease. Presently, interferon alfa based therapies, with or without ribavirin, are standard treatment for chronic hepatitis C virus infection. The most troublesome psychiatric side effects of interferon therapy in our patients are: insomnia, irritability, anxiety, mood changes, short temper, emotional and affective lability, impaired cognitive function, apathy, loss of motivation and the most serious depression with or without suicidal ideas. Material and methods In our study we treated 82 patients chronically infected with HCV divided into 3 groups: the first group of 31 patients (20 male and 11 female received IFN-alfa in standard doses of 3 MU three times a week (t.i.w during 24 weeks; the second group of 36 patients (25 male and 11 female received IFN-alfa, 3 MU t.i.w plus ribavirin 1000-1200 mg per day during 24 weeks; the third group of 15 patients (11 male and 4 female received IFN-alfa, 3 MU t.i.w plus ribavirin 1000-1200 mg per day during 48 weeks. The follow-up period after therapy in all groups lasted 24 weeks. Results During treatment, we observed at least one psychiatric side effect in 21 (26% patients: insomnia in 11 (13%, emotional and affective lability in 9 (11%, anxiety, irritability and short temper in 8 (10%, impaired cognitive function in 7 (8% apathia and loss of motivation in 6 (7% treated patients. Depression, the most serious side effect, was established in 8 (10% patients. All of these side effects were observed during later stages of treatment (between 5th and 22nd weeks of treatment. The incidence of all psychiatric side effects was significantly higher in women than in men (p < 0,01. We observed higher prevalence of depression among patients with history of alcohol and drug abuse. Treatment was temporarily discontinued (from 2 to 4 weeks in all patients with depression, but it was not

However, side effects and complications may occur, and its clinical appearance on the oral mucosa can be similar to that of inflammatory or neoplastic disease. The aim of this research was to compare the clinical and histopathologic responses to PMMA injected by two different methods. Twenty-two rats received an injection of PMMA using the tunneling technique (gold standard, with subcutaneous deposition of the filler in the face, or a variation of the technique with transcutaneous submucosal deposition of the filler in the cheek. The tissue reaction was analyzed clinically every 24 hours during the first week, then once a week for the following 3 months. Histologic evaluation was based on the local inflammatory response to the filler. No clinical changes were observed during the initial evaluation period (0–14 days. After 14 days, only the submucosal group showed extra-oral enlargement (n=4, 18.2%. Histopathologic analysis revealed nodule formation in four animals (18.2% in the submucosal group, with no nodules observed in the subcutaneous group. The data obtained in this study demonstrate that the technique used to deliver the filler may influence the risk of adverse reactions.

  18. Transplacental exposure to AZT induces adverse neurochemical and behavioral effects in a mouse model: protection by L-acetylcarnitine.

    Anna Rita Zuena

    Full Text Available Maternal-fetal HIV-1 transmission can be prevented by administration of AZT, alone or in combination with other antiretroviral drugs to pregnant HIV-1-infected women and their newborns. In spite of the benefits deriving from this life-saving prophylactic therapy, there is still considerable uncertainty on the potential long-term adverse effects of antiretroviral drugs on exposed children. Clinical and experimental studies have consistently shown the occurrence of mitochondrial dysfunction and increased oxidative stress following prenatal treatment with antiretroviral drugs, and clinical evidence suggests that the developing brain is one of the targets of the toxic action of these compounds possibly resulting in behavioral problems. We intended to verify the effects on brain and behavior of mice exposed during gestation to AZT, the backbone of antiretroviral therapy during human pregnancy. We hypothesized that glutamate, a neurotransmitter involved in excitotoxicity and behavioral plasticity, could be one of the major actors in AZT-induced neurochemical and behavioral alterations. We also assessed the antioxidant and neuroprotective effect of L-acetylcarnitine, a compound that improves mitochondrial function and is successfully used to treat antiretroviral-induced polyneuropathy in HIV-1 patients. We found that transplacental exposure to AZT given per os to pregnant mice from day 10 of pregnancy to delivery impaired in the adult offspring spatial learning and memory, enhanced corticosterone release in response to acute stress, increased brain oxidative stress also at birth and markedly reduced expression of mGluR1 and mGluR5 subtypes and GluR1 subunit of AMPA receptors in the hippocampus. Notably, administration during the entire pregnancy of L-acetylcarnitine was effective in preventing/ameliorating the neurochemical, neuroendocrine and behavioral adverse effects induced by AZT in the offspring. The present preclinical findings provide a

  19. Delayed immune mediated adverse effects to hyaluronic acid fillers: report of five cases and review of the literature

    2015-03-01

    Full Text Available Hyaluronic acid (HA fillers in cosmetic medicine have been considered relatively safe, though fillers used in European countries and throughout the world are not necessarily approved by the Food and Drug Administration. As their use continues to expand worldwide, physicians in a wide range of medical specialties are authorized to perform HA injections, including general medicine practitioners and even dentists. An increasing number of reports have appeared regarding side effects to these products. It is now known that reactions to Hyaluronic acid are related not only to technical faults of the injections, but also to immune responses, including delayed hypersensitivity and granulomatous reactions. Herein, we describe five cases treated by a variety of treatment modalities, all with delayed reactions to different brands of hyaluronic acid fillers. As there is currently no standardization of treatment options of adverse effects, these cases accentuate the debate regarding the approach to the individual patient and the possible need for pre-testing in patients with an atopic tendency.

    Considers in detail the general concepts and principles relevant to the adverse late effects of cancer treatment. Explains the molecular, cytologic and histopathologic events that lead to altered physiologic and metabolic functions and their clinical manifestations. Includes chapters on legal issues, economic aspects, nursing, psychological issues and quality of life. The literature on the late effects of cancer treatment is widely scattered in different journals since all major organ systems are affected and management is based on a variety of medical and surgical treatments. The aim of ALERT - Adverse Late Effects of Cancer Treatment is to offer a coherent multidisciplinary approach to the care of cancer survivors. The central paradigm is that cytotoxic multimodal therapy results in a perpetual cascade of events that affects each major organ system differently and is expressed continually over time. Essentially, radiation and chemotherapy are intense biologic modifiers that allow for cancer cure and cancer survivorship but accelerate senescence of normal tissues and increase the incidence of age-related diseases and second malignant tumors. Volume 1 of this two-volume work focuses on the general concepts and principles relevant to late effects and on the dynamic interplay of molecular, cytologic and histopathologic events that lead to altered physiologic and metabolic functions and their clinical manifestations. Chapters are also included on legal issues, economic aspects, nursing, psychological issues and quality of life.

    Diesel engine emissions are among the most prevalent anthropogenic pollutants worldwide, and with the growing popularity of diesel-fueled engines in the private transportation sector, they are becoming increasingly widespread in densely populated urban regions. However, a large number of toxicological studies clearly show that diesel engine emissions profoundly affect human health. Thus the interest in the molecular and cellular mechanisms underlying these effects is large, especially concerning the nature of the components of diesel exhaust responsible for the effects and how they could be eliminated from the exhaust. This review describes the fundamental properties of diesel exhaust as well as the human respiratory tract and concludes that adverse health effects of diesel exhaust not only emerge from its chemical composition, but also from the interplay between its physical properties, the physiological and cellular properties, and function of the human respiratory tract. Furthermore, the primary molecular and cellular mechanisms triggered by diesel exhaust exposure, as well as the fundamentals of the methods for toxicological testing of diesel exhaust toxicity, are described. The key aspects of adverse effects induced by diesel exhaust exposure described herein will be important for regulators to support or ban certain technologies or to legitimate incentives for the development of promising new technologies such as catalytic diesel particle filters.

    Prenatal exposure to environmental chemicals or drugs has been associated with functional or structural deficits and the development of diseases in later life. For example, developmental neurotoxicity (DNT) is triggered by lead, and this compound may predispose to neurodegenerative diseases in later life. The molecular memory for such late consequences of early exposure is not known, but epigenetic mechanisms (modification of the chromatin structure) could take this role. Examples and underlying mechanisms have been compiled here for the field of DNT. Moreover, we addressed the question as to what readout is suitable for addressing drug memory effects. We summarize how complex developmental processes can be modelled in vitro by using the differentiation of human stem cells. Although cellular models can never replicate the final human DNT phenotype, they can model the adverse effect that a chemical has on key biological processes essential for organ formation and function. Highly information-rich transcriptomics data may inform on these changes and form the bridge from in vitro models to human prediction. We compiled data showing that transcriptome analysis can indicate toxicity patterns of drugs. A crucial question to be answered in our systems is when and how transcriptome changes indicate adversity (as opposed to transient adaptive responses), and how drug-induced changes are perpetuated over time even after washout of the drug. We present evidence for the hypothesis that changes in the histone methylation pattern could represent the persistence detector of an early insult that is transformed to an adverse effect at later time-points in life.

    Full Text Available Ischemia and hemorrhage are the conditions which may lead to stroke. As stroke is a medical emergency, treated with medications such as aspirin, clopidogrel and dipyridamole. In the present study the combination and individual adverse effects of aspirin and clopidogrel medication were studied. The study during was around nine months in one of the private hospital at Hyderabad, Andhra Pradesh, India. Adverse effects evaluation was based on WHO guide lines and Naranjo’s Algorithm. Total 69 stroke patients were taken in to studies. 46 (66.66% were males and 23 (33.33% were females. The number of ischemic stroke patients was 39(56.5% and hemorrhage stroke was 30(43.4%. Among 41 patients, 19 patients was on Aspirin (46.34%, 10 patients was on clopidogral (24.34% and 12 patients was on combinations medication (29.26%. Adverse effects reported among the antiplatelate users were 6 patients. Among these 6 patients 4 patients were observed with upper gastrointestinal bleeding (UGI the overall percentage was 66.66% and 2 patients were observed with Vomiting, the overall percentage was 33.33%. In this study, the relative risk reduction for secondary stroke prevention was 37% with use of a combination of extended- release dipyridamole and aspirin. Importantly, the risk of major bleeding attributable to the combination therapy was no greater than that seen with aspirin alone. The benefit of clopidogrel over aspirin for the prevention of vascular events was a relative risk reduction of 8.7%.In addition, there was less major bleeding in the clopidogrel group, yielding a relative net benefit of about 10%. This study revels clopidogrel is the safe drug when compared with Aspirin and as well as combination therapy.

  5. Germline glutathione S-transferase variants in breast cancer: Relation to diagnosis and cutaneous long-term adverse effects after two fractionation patterns of radiotherapy

    International Nuclear Information System (INIS)

    Purpose: To explore whether certain glutathione S-transferase (GST) polymorphisms are associated with an increased risk of breast cancer or the level of radiation-induced adverse effects after two fractionation patterns of adjuvant radiotherapy. Methods and Materials: The prevalence of germline polymorphic variants in GSTM1, GSTP1, and GSTT1 was determined in 272 breast cancer patients and compared with that in a control group of 270 women from the general population with no known history of breast cancer. The genetic variants were determined using multiplex polymerase chain reaction followed by restriction enzyme fragment analysis. In 253 of the patients surveyed for radiotherapy-induced side effects after a median observation time of 13.7 years (range, 7-22.8 years), the genotypes were related to the long-term effects observed after two fractionation patterns (treatment A, 4.3 Gy in 10 fractions for 156 patients; and treatment B, 2.5 Gy in 20 fractions for 97; both administered within a 5-week period). Results: None of the GST polymorphisms conferred an increased risk of breast cancer, either alone or in combination. Compared with treatment B, treatment A was followed by an increased level of moderate to severe radiation-induced side effects for all the endpoints studied (i.e., degree of telangiectasia, subcutaneous fibrosis and atrophy, lung fibrosis, costal fractures, and pleural thickening; p <0.001 for all endpoints). A significant association was found between the level of pleural thickening and the GSTP1 Ile105Val variant. Conclusion: The results of this study have illustrated the impact of hypofractionation on the level of adverse effects and indicated that the specific alleles of GSTP1, M1, and T1 studied here may be significant in determining the level of adverse effects after radiotherapy

    The effects of high, medium and low levels of perinatal complications and family adversity on intelligence quotient (IQ) scores were examined in a large sample of Dunedin children tested every second year in the age group 3-13 years. The aim was to test the hypothesis that favourable environmental circumstances attenuate the effects of perinatal complications on later cognitive ability. The results did not support this hypothesis but rather suggested that perinatal complications and family adversity have independent adverse effects on the development of children's cognitive ability.

  7. Presentation and management of docetaxel-related adverse effects in patients with breast cancer

    International Nuclear Information System (INIS)

    The taxane chemotherapeutic agent docetaxel has been utilized in the management of breast cancer in the adjuvant, neoadjuvant and metastatic setting. Although well tolerated by the majority of patients, docetaxel toxicity may limit the dose which can be administered. Adverse events include infusion reactions, febrile neutropenia, fatigue, fluid retention, pneumonitis, cutaneous and nail toxicity, epiphora and lacrimal duct stenosis, gastrointestinal complications, and neuropathies. In this review, we explore these complications and how they can be effectively managed to improve patient quality of life during and following docetaxel therapy

    Management of bipolar disorder during pregnancy often involves medications with potential adverse effects, including risks to the mother and fetus. Although some specifics are known, many medications continue to have incompletely characterized reproductive safety profiles. Women with bipolar disorder who are planning pregnancy face challenging decisions about their treatment; careful risk-benefit discussions are necessary. With the goal of further informing these discussions, this article reviews the data currently available regarding medication safety in the management of bipolar disorder during pregnancy, with specific attention to lithium, valproic acid, lamotrigine, carbamazepine, and antipsychotic medications.

    Full Text Available Methotrexate (MTX is one of the most commonly used medicines in the treatment of psoriatic arthritis. The drug can produce steatosis and cirrhosis. Autoimmune hepatitis is a rare and serious adverse effect. We describe the case of a 53-year-old woman who developed autoimmune hepatitis after a long-term use of MTX for psoriatic arthritis. Hepatitis was completely resolved 4 months after stopping this drug. The pathophysiologic mechanisms of a drug-induced autoimmunity are unclear and complex. This report confirms the need to monitor liver enzymes carefully in patients using long-term treatment with MTX for psoriasis or rheumatoid arthritis.

    Central venous catheter techniques find at present use for administering of NPT, for the drug injection ( especially chemiotherapeutic drugs) because of the possible damage of a few substances when perfused in a peripheral way. At present port-a-cath find their most extensive use: these are systems which can be set up and tolerated for many months. For the access to subclavian vein must be necessary put in supine decubitus, with light Trendelenburg position, with the opposite arm along the body and the head turned on the opposite side. In this way the clavicle is in perpendicular position with regard to the sternal handlebar, except for patient affected with bpco, kypho-scoliosis, scapular-homeral arthrosis. In these patients the clavicle can put on a particular course, oblique and upper as to the sternal articular face. So there is a serious obstacle to the passage to the metal needle under the clavicle. KEY WORDS: Chemiotherapy, CVC, NPT, Port-a-Cath. PMID:23103553

    Full Text Available Granular materials have numerous industrial and geophysical applications. However, many phenomenon exhibited by granular media are not yet fully explained. Nowadays simulation has emerged as an important tool to investigate the complex properties exhibited by granular media. The influence of side walls movement of a granular column is investigated by discrete element, molecular dynamics simulations. The evolution of stress profile and deflection of vertical stresses is due to different bead sizes, coefficient of friction between grains and confining wall is investigated by using large-scale discrete element MD simulations in 3D. In such a configuration, it is found that apparent mass systemically increases with the increase in diameter of granules. As soon as the wall stops moving, the column attains equilibrium. The stress profiles are in good agreement with the Janssen form for high friction coefficient, while some deviations remain for smaller values of friction coefficient. The wall movement augments the number of particle-wall and particle-particle forces at the Coulomb criterion. The results indicate the variation in shielding of vertical stresses in granular column; it can be attributed to the fiction between the beads and the confining walls of the container.

    1998-01-01

    Full Text Available We evaluated the components of the Fuenzalida-Palacios antirabies vaccine, which is till used in most developing countries in human immunization for treatment and prophylaxis. This vaccine is prepared from newborn mouse brains at 1% concentration. Even though the vaccine is considered to have a low myelin content, it is not fully free of myelin or of other undesirable components that might trigger adverse effects after vaccination. The most severe effect is a post-vaccination neuroparalytic accident associated with Guillain-Barré syndrome. In the present study we demonstrate how the vaccines produced and distributed by different laboratories show different component patterns with different degrees of impurity and with varying protein concentrations, indicating that production processes can vary from one laboratory to another. These differences, which could be resolved using a better quality control process, may affect and impair immunization, with consequent risks and adverse effects after vaccination. We used crossed immunoelectrophoresis to evaluate and demonstrate the possibility of quality control in vaccine production, reducing the risk factors possibly involved in these immunizing products.

    Topical steroids are known for their anti-inflammatory properties and are commonly prescribed to treat many adverse skin conditions such as eczema and psoriasis. While these treatments are known to be effective, adverse effects including skin atrophy are common. In this study, the progression of these effects is investigated in an in vivo mouse model using multimodal optical microscopy. Utilizing a system capable of performing two-photon excitation fluorescence microscopy (TPEF) of reduced nicotinamide adenine dinucleotide (NADH) to visualize the epidermal cell layers and second harmonic generation (SHG) microscopy to identify collagen in the dermis, these processes can be studied at the cellular level. Fluorescence lifetime imaging microscopy (FLIM) is also utilized to image intracellular NADH levels to obtain molecular information regarding metabolic activity following steroid treatment. In this study, fluticasone propionate (FP)-treated, mometasone furoate (MF)-treated and untreated animals were imaged longitudinally using a custom-built multimodal optical microscope. Prolonged steroid treatment over the course of 21 days is shown to result in a significant increase in mean fluorescence lifetime of NADH, suggesting a faster rate of maturation of epidermal keratinocytes. Alterations to collagen organization and the structural microenvironment are also observed. These results give insight into the structural and biochemical processes of skin atrophy associated with prolonged steroid treatment. PMID:26739196

    Atopic eczema is a chronic inflammatory disease affecting about 30% of Australian and New Zealand children. Severe eczema costs over AUD 6000/year per child in direct medical, hospital and treatment costs as well as time off work for caregivers and untold distress for the family unit. In addition, it has a negative impact on a child's sleep, education, development and self-esteem. The treatment of atopic eczema is complex and multifaceted but a core component of therapy is to manage the inflammation with topical corticosteroids (TCS). Despite this, TCS are often underutilised by many parents due to corticosteroid phobia and unfounded concerns about their adverse effects. This has led to extended and unnecessary exacerbations of eczema for children. Contrary to popular perceptions, (TCS) use in paediatric eczema does not cause atrophy, hypopigmentation, hypertrichosis, osteoporosis, purpura or telangiectasia when used appropriately as per guidelines. In rare cases, prolonged and excessive use of potent TCS has contributed to striae, short-term hypothalamic-pituitary-adrenal axis alteration and ophthalmological disease. TCS use can also exacerbate periorificial rosacea. TCS are very effective treatments for eczema. When they are used to treat active eczema and stopped once the active inflammation has resolved, adverse effects are minimal. TCS should be the cornerstone treatment of atopic eczema in children.

    Plants are of relevance to dermatology for both their adverse and beneficial effects on skin and skin disorders respectively. Virtually all cultures worldwide have relied historically, or continue to rely on medicinal plants for primary health care. Approximately one-third of all traditional medicines are for treatment of wounds or skin disorders, compared to only 1-3% of modern drugs. The use of such medicinal plant extracts for the treatment of skin disorders arguably has been based largely on historical/anecdotal evidence, since there has been relatively little data available in the scientific literature, particularly with regard to the efficacy of plant extracts in controlled clinical trials. In this article therefore, adverse and beneficial aspects of medicinal plants relating to skin and skin disorders have been reviewed, based on recently available information from the peer-reviewed scientific literature. Beneficial aspects of medicinal plants on skin include: healing of wounds and burn injuries (especially Aloe vera); antifungal, antiviral, antibacterial and acaricidal activity against skin infections such as acne, herpes and scabies (especially tea tree (Melaleuca alternifolia) oil); activity against inflammatory/immune disorders affecting skin (e.g. psoriasis); and anti-tumour promoting activity against skin cancer (identified using chemically-induced two-stage carcinogenesis in mice). Adverse effects of plants on skin reviewed include: irritant contact dermatitis caused mechanically (spines, irritant hairs) or by irritant chemicals in plant sap (especially members of the Ranunculaceae, Euphorbiaceae and Compositae plant families); phytophotodermatitis resulting from skin contamination by plants containing furocoumarins, and subsequent exposure to UV light (notably members of the Umbelliferae and Rutaceae plant families); and immediate (type I) or delayed hypersensitivity contact reactions mediated by the immune system in individuals sensitized to plants

    Abstract Recent studies have demonstrated that atrial fibrillation significantly increases the risk of adverse clinical outcomes in high cardiovascular disease risk subjects. Application of renin–angiotensin–aldosterone system blockers for prevention of recurrence of atrial fibrillation and adverse clinical outcomes in subjects with atrial fibrillation is a theoretically appealing concept. However, results of clinical trials evaluating the effect of renin–angiotensin–aldosterone blockers on adverse clinical outcomes in high cardiovascular disease risk subjects with atrial fibrillation remain inconclusive. A pooled study of 6 randomized controlled trials assessing the efficacy of renin–angiotensin–aldosterone blockers on subjects with atrial fibrillation was performed. A total of 6 randomized controlled trials enrolled a total of 53,510 patients followed for 1 to 5 years. RAAS blockade therapy was associated with 14% reduction in the incidence of heart failure (OR: 0.86, [95%CI: 0.76– 0.97], P=0.018) and 17% reduction in the incidence of CVE (OR: 0.83, [95%CI: 0.70–0.99], P = 0.038). The corresponding decline in absolute risk against heart failure (ARR: 1.4%, [95%CI: 0.2–2.6%], P = 0.018) and CVE (ARR: 3.5%, [95%CI: 0.0–6.9%], P = 0.045) in the AF group was much higher than the non-AF group for heart failure (ARR: 0.4%, [95%CI: 0.0–0.7%], P = 0.057) and CVE (ARR: 1.6%, [95%CI: –0.1% to 3.3%], P = 0.071). No significant effect was noted on all-cause or cardiovascular mortality, stroke, or myocardial infarction. This study suggests that RAAS blockade offers protection against heart failure and cardiovascular events in high cardiovascular disease risk subjects with atrial fibrillation. PMID:27368043

    At present, the potential to decrease atmospheric carbon dioxide concentrations by manipulating the carbon cycle (carbon geoengineering) is being considered as a fourth possible option for addressing anthropogenic climate change, alongside emissions reductions, adaptation and solar geoengineering. This study sets out to assess the effectiveness and potential side-effects of ocean alkalinity enhancement, or ';liming the ocean', as a means to slow the current increase in atmospheric CO2. In order to achieve this, an Earth system model (cGENIE) was used to run both individual simulations as well as a number of 934-member ensembles, to assess each surface ocean grid cell individually, for effectiveness and side-effects of ocean alkalinity enhancement. Effectiveness and side-effects were considered both temporally and spatially and under both steady-state scenarios (of 1x, 2x and 4x pre-industrial pCO2), and using RCP scenarios 4.5 and 8.5. Some consideration of the amount of lime potentially required to have a useful impact on atmospheric CO2 concentration and ocean acidification has also been carried out and compared to current mining capabilities, as an initial step towards considering the feasibility of such an intervention. This research aims to inform the emerging debate around geoengineering by providing an initial insight into where, when and how frequently lime could be used to most efficiently contribute to efforts to slow the rate of increasing atmospheric CO2 concentrations, as well as insights into the caveats and side-effects that may accompany ocean alkalinity enhancement interventions.

    Attention-deficit hyperactivity disorder (ADHD) is a common psychiatric disorder in children which manifests with hyperactivity, impulsivity, and/or inattention. Several drugs are used in treatment of ADHD. Stimulants, atomoxetine, anti-depressants, and bupropion are common medications used in the treatment of ADHD. Stimulants are widely used as the first line treatment in children with ADHD. Their mechanism of action is the release of dopamine and norepinephrine in central nervous system. Methylphenidate is the most common stimulant used for the treatment of ADHD. Methylphenidate significantly reduces ADHD symptoms in children both at home and school and improves their social skills. Methylphenidate is safe in healthy children and has shown to have no cardiac side effects in these patients. Other medications include: Atomoxetine, Amphetamines, Clonidine, Melatonin, and anti-depressants. Effects, side effects, and mechanism of action these drugs have been discussed in this paper.

    Full Text Available Side weir is one of the most common hydraulic structures, which is used as a deviatory structure in rivers, irrigation and drainage channels and also in urban sewage collection systems.Semi-circular side weir can be an solution for increasing discharge coefficientC_m. In present research the semi-circular side weir has been studied to find the influence of hydraulic and geometry variables on the C_m value. Furthermore semi-circular side weir has been compared with labyrinth side weir with a beak angle 〖90〗^°.105 experimental tests were conducted on the semi-circular and labyrinth side weir. Upstream Froude number and discharge coefficient were calculated. The results showed that semi-circular side weir has higher coefficient value in comparison with rectangular side weir and labyrinth side weir when beak angle is〖90〗^°. An inverse relationship between C_m Value and 〖Fr〗_1 was found. Also increase in dimensionless height of weir (w⁄y_1 was causes the C_m value enhances. A new equation was developed to calculate C_m.

  2. Dynamics of energy-related CO2 emissions in China during 1980 to 2002: The relative importance of energy supply-side and demand-side effects

    International Nuclear Information System (INIS)

    Based on a newly developed model that integrates energy production, transformation and consumption processes, this paper compares the relative importance of some traditionally recognized factors operating on the energy demand side with a body of newly defined factors on the supply side, in terms of their contribution to trends in China's CO2 emissions related to the total primary energy supply (C-TPES). Before 1996, changes in China's C-TPES were mainly driven by changes on the energy demand side. Factors operating on the energy supply side played trivial roles. During the period 1996-2000, however, increasing demand-side effects declined dramatically and at the same time decreasing effects from supply side expanded significantly. Such changes resulted directly in a decline in the C-TPES. The decreasing effects from international trade as well as statistical imbalances between supply and demand reinforced the declining trend. The shrinkage of demand side effects mainly arose from the slowdown of economic growth and speed of decrease in energy intensity. The expansion of supply-side effects was principally attributed to the speed of decrease in gross unit consumption in transformation sectors, especially in electricity sector. Therefore, the acceleration of efficiency improvements in end-use and transformation sectors accounted for the decline in the C-TPES over the period 1996-2000

    Polymethylmethacrylate (PMMA) has been widely used in the correction of wrinkles because of its long-lasting cosmetic improvements. However, side effects and complications may occur, and its clinical appearance on the oral mucosa can be similar to that of inflammatory or neoplastic disease. The aim of this research was to compare the clinical and histopathologic responses to PMMA injected by two different methods. Twenty-two rats received an injection of PMMA using the tunneling technique (gold standard), with subcutaneous deposition of the filler in the face, or a variation of the technique with transcutaneous submucosal deposition of the filler in the cheek. The tissue reaction was analyzed clinically every 24 hours during the first week, then once a week for the following 3 months. Histologic evaluation was based on the local inflammatory response to the filler. No clinical changes were observed during the initial evaluation period (0–14 days). After 14 days, only the submucosal group showed extra-oral enlargement (n=4, 18.2%). Histopathologic analysis revealed nodule formation in four animals (18.2%) in the submucosal group, with no nodules observed in the subcutaneous group. The data obtained in this study demonstrate that the technique used to deliver the filler may influence the risk of adverse reactions. PMID:26346665

    Herbal supplements have been used as adjuncts to medical therapy for many years by various cultures. Many consumers believe that because herbal supplements are natural products, they are somewhat safer or more effective than traditional prescribed medications. This is also one reason that alternative medicine is growing and gaining more popularity. On the other hand, adverse reactions to herbal supplements or their interactions with patients' current medications are no different than pharmaceutical medicines. We report a case of premature ventricular contraction associated with two herbal supplements. These products contained multiple different herbs and both included large doses of guarana. Guarana, which is found in some supplements marketed in U.S., contains a substantial amount of caffeine. Although the exact cause of tachycardia in our report is not proven, a large amount of caffeine consumption is thought to be a possible causal effect. The purpose of this report is to remind health care professionals to evaluate and educate patients on the use of herbal products and any potential adverse reactions, drug interactions, or possible toxicities.

    Gratitude has robust associations with multiple aspects of well-being. However, little research has explored whether the psychological benefits of gratitude extend to body image. We used a repeated measures experimental design to test whether a brief period of grateful reflection would buffer the adverse effect of exposure to thin-ideal media. Female undergraduates (N=67) completed three sessions one week apart. The conditions were specifically designed to isolate (a) the effects of viewing thin models on body dissatisfaction and (b) the moderating effect of grateful contemplation. Results showed that body dissatisfaction scores were lower for women who engaged in a brief period of grateful contemplation before viewing photographs of thin models than for women who reflected upon life hassles before viewing the same photographs. The magnitude of this decrease depended on BMI. Gratitude offers an innovative direction for future research directed toward helping women to accept their bodies. PMID:24958659

  7. Effects of roughness and adverse pressure gradient on the turbulence structure

    International Nuclear Information System (INIS)

    Highlights: • Adverse pressure gradient diminished the size of the hairpin packet over the smooth wall. • Adverse pressure gradient produced more intense ejection, sweep and interaction motions over smooth and rough walls. • The turbulence structure over the k-type rough wall is larger compared to the smooth wall. -- Abstract: The manuscript presents an experimental study of turbulent flows over smooth and rough walls in a channel that consists of an upstream parallel section to produce a fully developed channel flow and a diverging section to produce an adverse pressure gradient (APG) flow. The roughness element consists of two-dimensional transverse square ribs of nominal height, k = 3 mm that were spaced to produce pitch-to-height ratio of p/k = 2 and 8, corresponding to d-type and k-type rough walls. A particle image velocimetry system was used to conduct detailed velocity measurements over the smooth and rough walls in both the parallel and diverging sections. The mean defect velocity and Reynolds stresses as well as Galilean decomposition, quadrant decomposition, two-point velocity correlation and linear stochastic estimation were used to document the salient effects of APG and wall roughness on the flows. The results indicated that APG significantly augments turbulence level compared to the flows in the parallel section. The flow fields were populated with vortex cores that formed hairpin vortex packets. The packets were inclined at shallow angles relative to the wall as revealed by the two-point velocity correlation. The quadrant analysis revealed that the ejections, sweeps, and inward and outward interaction motions associated with the structures were influenced by roughness and APG. The existence of structures was further supported by linear stochastic estimates conditioned on the prograde vortices

    There are several case reports on risperidone-related bleeding; however, to our knowledge, there is no report about gingival bleeding associated with risperidone in the literature. We presented a case who experienced gingival bleeding when risperidone dose was increased to 0.5 mg/day, and subsided after decreasing the dose to 0.25 mg/day, suggesting a dose-dependent side-effect. The bleeding side effect of risperidone might be caused by several mechanisms, including 5-hydroxytryptamine 2A receptor antagonism. Although bleeding associated with risperidone is rarely reported, clinicians should be aware of this side effect. PMID:27121433

    The efficacy of an anti-prostaglandin, tolfenamic acid (T.A.), in the prevention of side-effects after insertion of a copper-T200 intrauterine contraceptive device (I.U.D.) was evaluated in a double-blind trial in 160 women. T.A. relieved pain and reduced bleeding after insertion and during three subsequent menstruations without serious side-effects. A scoring system for the assessment of I.U.D. side-effects showed that the acceptability of I.U.D. was significantly better in women treated with T.A. than in those given placebo. PMID:79760

  16. Adverse Cardiovascular Effects of Nitrous Oxide: It is not all about Hyperhomocysteinaemia

    Full Text Available Once admired for its supposed safety, nitrous oxide is presently blamed to increase adverse cardiovascular effects through augmenting plasma homocysteine concentrations (1, 2. Hemodynamic alterations following the administration of nitrous oxide are extremely complicated and sometimes contradictory. Enhanced venous return, arterial pressure, pulmonary and systemic vascular resistance, cardiac output, pupillary dilation and diaphoresis occur under nitrous oxide administration consistent with sympathomimetic properties of nitrous oxide (3. Conversely, reductions in arterial pressure are also probable, especially in patients with coronary artery disease. Nitrous oxide can also depress myocardial contractility due to decreased availability of Ca2+ for contractile activation; yet, myocardial relaxation kinetics remains intact (4. In the presence of a volatile anesthetic, nitrous oxide decreases MVO2 (Myocardial oxygen consumption and myocardial O2 extraction which may exacerbate myocardial ischemia during concomitant reductions in arterial pressure in patients with coronary artery disease. Consequently, it could be conjectured that probable adverse cardiovascular effects following nitrous oxide administration are variable and consequent of a multi-variable phenomenon rather than a single variable such as increased levels of homocysteine. Studied purely focusing on the effects of nitrous oxide are difficult to conduct due to the numerous confounding factors.In a study by Myles et al., hyperhomocysteinemia has been introduced as the source of the adverse cardiovascular effects of nitrous oxide. However, in this study, increased inspired oxygen concentrations were used to overcome arterial desaturation (1. Given the fact that a constant volume and flow rates are used throughout the anesthesia in a particular patient, increasing the concentrations of oxygen would be associated with decreased delivered nitrous oxide and volatile anesthetic concentrations

    Isotretinoin (Iso) is the most effective drug against severe nodulocystic acne. As a synthetic oral retinoid, Iso exerts its actions by modulating cell growth and differentiation. Targeting all the pathophysiologic processes in acne development, Iso has been considered to be an unique drug, however it has several side effects. While chelitis, xerosis, ocular sicca, arthralgia, myalgia, headache, hyperlipidemia are the most common side effects, teratogenicity and depressive symptoms are the most concerning ones. In addition, Iso has unusual side effects which have been described for the first time in the literature. Here, we report a remarkable side effect of Iso in a 23-years-old male patient with retinoid dermatitis affecting the external uretral meatus. To our knowledge, only few cases of retinoid dermatitis in the urethral mucosa due to Iso have been reported in the literature so far. PMID:24964168

    Multipotent mesenchymal stromal cells [also referred toas mesenchymal stem cells (MSCs)] are a heterogeneoussubset of stromal cells. They can be isolated from bonemarrow and many other types of tissue. MSCs arecurrently being tested for therapeutic purposes (i.e.,improving hematopoietic stem cell engraftment, managinginflammatory diseases and regenerating damagedorgans). Their tropism for tumors and inflamed sites andtheir context-dependent potential for producing trophicand immunomodulatory factors raises the question asto whether MSCs promote cancer and/or infection. Thisarticle reviews the effect of MSCs on tumor establishment,growth and metastasis and also susceptibility to infectionand its progression. Data published to date shows aparadoxical effect regarding MSCs, which seems todepend on isolation and expansion, cells source anddose and the route and timing of administration.

We have proactively monitored the safety profiles of Duhuo Jisheng Tang (DJT, Suan Zao Ren Tang (SZRT, and TMN-1. A list of adverse events (AEs, complete blood counts, and liver and kidney function tests were obtained from the participants during their scheduled hospital visits. Retrospective observational studies were conducted based on the reimbursement database of the National Health Insurance system, Taiwan, to explore the relationship between the use of TCM that have been adulterated by aristolochic acid and the risk from both nephrotoxins and carcinogens. Results. A total of 221, 287, and 203 AEs were detected after SZRT, DJT, and TMN-1 had been taken, respectively. Dizziness, headache, stomach ache, and diarrhea were judged to be probably related to SZRT treatment. Retrospective observational studies found an association between the consumption of aristolochic acid-containing Chinese formulae such as Mu Tong and an increased risk of CKD, ESRD, and urinary tract cancer. Conclusion. Prospective and retrospective observational studies seem to have specific advantages when investigating the safety and adverse effects of TCM therapies, as well as possibly other alternative/complementary therapies.

    The assessment procedure of new synthetic illicit drugs that are not documented in the UN treaty on psychotropic drugs was evaluated using a modified Electre model. Drugs were evaluated by an expert panel via the open Delphi approach, where the written score was discussed on 16 items, covering medical, health, legal, and criminalistic issues of the drugs. After this face-to-face discussion the drugs were scored again. Taking the assessment of ketamine as an example, it appeared that each expert used its own scale to score, and that policymakers do not score deviant from experts trained in the medical-biological field. Of the five drugs evaluated by the panel, p-methoxy-metamphetamine (PMMA), gamma-hydroxybutyric acid (GHB), and 4-methylthio-amphetamine (MTA) were assessed as more adverse than ketamine and psilocine and psilocybine-containing mushrooms. Whereas some experts slightly adjusted during the assessment procedure their opinion on ketamine and PMMA, the opinion on mushrooms was not affected by the discussion held between the two scoring rounds. All experts rank the five drugs in a similar way on the adverse effect scale i.e., concordance scale of the Electre model, indicating unanimity in the expert panel with respect to the risk classification of these abused drugs.

    Despite the significant contributions from previous studies about the prevalence of problematic Internet use (PIU) among adolescents in Europe, important questions remain regarding adverse consequences of PIU. This study aims to assess the relation between duration of Internet use and adverse psychosocial effects among adolescents from six European countries. The final sample included 7,351 adolescents (50.8% male and 49.2% female; mean age: 14.6±1.90) recruited from randomly selected schools within the six study sites. Results showed that 12.9% of adolescents used Internet more than 20 hours per week. There was a significant relationship between duration of Internet use and frequency of alcohol, tobacco, cannabis and other illegal drug use. Duration of Internet use is also significantly associated with school problems, with use of slot machines and with other psychosocial problems. These findings highlight the need to strengthen preventive efforts for reducing PIU and related consequences among adolescents. Key Words: Internet, adolescents, psychosocial problems. PMID:25314040

    Carrageenan (CRG) is a family of natural polysaccharides derived from seaweeds and has widely been used as food additives. In the past decade, owing to its attractive physicochemical properties, CRG has been developed into versatile biomaterials vehicles for drug delivery. Nevertheless, studies also emerged to reveal its adverse effects on the biological system. In this review, we critically appraise the latest literature (two thirds since 2008) on the development of CRG-based pharmaceutical vehicles and the perspective of using CRG for broader biomedical applications. We focus on how current strategies exploit the unique gelling mechanisms, strong water absorption and abundant functional groups of the three major CRG varieties. Notably, CRG-based matrices are demonstrated to increase drug loading and drug solubility, enabling release of orally administrated drugs in zero-order or in a significantly prolonged period. Other amazing features, such as pH-sensitivity and adhesive property, of CRG-based formulations are also introduced. Finally, we discuss the adverse influence of CRG on the human body and then suggest some future directions for the development of CRG-based biomaterials for broader applications in biomedicine.

    Auxiliary feedwater system (AFWS) recirculation flow paths adopted air operated valves (AOVs) which could fail close on loss of instrument air (LOIA) event. So the AOVs and recirculation paths are closed on LOIA event, which could result in Auxiliary feedwater (AFW) pump(s) damage, which contributes greatly to core damage frequency (CDF).. On February 2002, the USNRC issued an inspection finding related to potential common cause failure of AOVs in AFWS recirculation flow paths on loss of instrument air system in Point Beach nuclear power plant (Pt. Beach). The AOVs have been removed from AFWS recirculation paths in the design of Korea standard nuclear power plant (KSNP). So, there is no possibility of above mentioned failure event in KSNP. It would be beneficial to evaluate the significance of adverse effect of AOVs in AFWS recirculation paths to realize the importance of maintaining AFWS recirculation paths always open. In this study, the AFWS modeling of Ulchin unit 3 and 4 was modified to model the AOVs in AFW recirculation flow paths to evaluate the change in CDF, which is caused by the adverse effect of AOV with operation mode of 'fails close' on LOIA event. It is concluded that the existence of AOV with 'fail close' design in AFWS MDP recirculation paths results in CDF increase of 131%, which is significant adverse effect on plant safety.. In this regard, the improved Westinghouse design and KSNP design had removed the AOVs from AFWS MDP recirculation paths. However, a couple of units with old Westinghouse design, Kori 1 and 2, still have AOVs in AFWS MDP recirculation paths and throttle back operation of AFWS is in effect. Although those AOVs adopt 'fail open' design to prevent above mentioned inadvertent closure, considering the big increase in CDF, there still exists considerable risk from the possibility of 'failure to open' during this throttle back operation. Therefore, it is strongly recommended that any

    Full Text Available Symbiotic association between arbuscular mycorrhizal (AM species and host plant roots improves plant growth and protects them from several abiotic stress factors. In the present study, the effect of Glomus mosseae and Glomus fasciculatum as an individual inoculation and in combination was studied on two legumes (Glycine max and Cyamopsis tetragonoloba under soil salinity stress gradient [1.04 (control to 8.26 dS/m]. Individual and co-inoculation of both the AM fungi alleviated adverse salt effect, with improvement in plant dry weight matter and biochemical parameters. However, these two isolates worked better in combination with respect to higher accumulation of soluble carbohydrate, reducing sugar, protein, proline concentration etc. C. tetragonoloba showed better response as compared to G. max in relation to improvement in nutritional profile under salt stress after AM treatment. As compared to non-mycorrhizal counterparts, co-inoculation with G. mosseae and G. fasciculatum in C. tetragonoloba enhanced total chlorophyll (14.83% at soil salinity of 3.78 dS/m, soluble carbohydrate (17.26% at soil salinity of 5.94 dS/m, proline (8.79% at soil salinity of 3.78 dS/m while exposed to different soil salinity levels. Also, co-colonization with both the isolates showed more root colonization (% and may be responsible for the better effect in salt stress alleviation. Electrolyte leakage of mycorrhizal plants was lowered at soil salinity gradient of 2.10 to 8.26 dS/m and hence, maintained membrane stability. These two isolates can be utilized as bio-inoculant in alleviation of adverse salt effect in soil in association with the two test legume plants.

    The link between poverty and children's health is well recognized. Even temporary poverty may have an adverse effect on children's health, and data consistently support the observation that poverty in childhood continues to have a negative effect on health into adulthood. In addition to childhood morbidity being related to child poverty, epidemiologic studies have documented a mortality gradient for children aged 1 to 15 years (and adults), with poor children experiencing a higher mortality rate than children from higher-income families. The global great recession is only now very slowly abating for millions of America's children and their families. At this difficult time in the history of our nation's families and immediately after the 50th anniversary year of President Lyndon Johnson's War on Poverty, it is particularly germane for the American Academy of Pediatrics, which is "dedicated to the health of all children," to publish a research-supported technical report that examines the mediators associated with the long-recognized adverse effects of child poverty on children and their families. This technical report draws on research from a number of disciplines, including physiology, sociology, psychology, economics, and epidemiology, to describe the present state of knowledge regarding poverty's negative impact on children's health and development. Children inherit not only their parents' genes but also the family ecology and its social milieu. Thus, parenting skills, housing, neighborhood, schools, and other factors (eg, medical care) all have complex relations to each other and influence how each child's genetic canvas is expressed. Accompanying this technical report is a policy statement that describes specific actions that pediatricians and other child advocates can take to attenuate the negative effects of the mediators identified in this technical report and improve the well-being of our nation's children and their families.

    Comprehensively documents potential late effects in all the normal tissue sites in the human body. Considers in detail the detection, diagnosis, management and prevention of effects and discusses prognostic outcomes. Clearly presents radiation risk factors and interactions with chemotherapy effects. Provides the most current evidence-based medicine for cancer care survivorship guidelines. The literature on the late effects of cancer treatment is widely scattered in different journals since all major organ systems are affected and management is based on a variety of medical and surgical treatments. The aim of ALERT - Adverse Late Effects of Cancer Treatment is to offer a coherent multidisciplinary approach to the care of cancer survivors. The central paradigm is that cytotoxic multimodal therapy results in a perpetual cascade of events that affects each major organ system differently and is expressed continually over time. Essentially, radiation and chemotherapy are intense biologic modifiers that allow for cancer cure and cancer survivorship but accelerate senescence of normal tissues and increase the incidence of age-related diseases and second malignant tumors. Volume 2 of this two-volume work comprehensively documents potential late effects in all the normal tissue anatomic sites in the human body. The detection, diagnosis, management and prevention of effects are all considered in detail, and prognostic outcomes are discussed. Radiation risk factors and interactions with chemotherapy effects are clearly presented. The text is accompanied by numerous supportive illustrations and tables.

    2014-10-01

    Energy drinks are increasingly popular among athletes and others. Advertising for these products typically features images conjuring great muscle power and endurance; however, the scientific literature provides sparse evidence for an ergogenic role of energy drinks. Although the composition of energy drinks varies, most contain caffeine; carbohydrates, amino acids, herbs, and vitamins are other typical ingredients. This report analyzes the effects of energy drink ingredients on prolonged submaximal (endurance) exercise as well as on short-term strength and power (neuromuscular performance). It also analyzes the effects of energy drink ingredients on the fluid and electrolyte deficit during prolonged exercise. In several studies, energy drinks have been found to improve endurance performance, although the effects could be attributable to the caffeine and/or carbohydrate content. In contrast, fewer studies find an ergogenic effect of energy drinks on muscle strength and power. The existing data suggest that the caffeine dose given in studies of energy drinks is insufficient to enhance neuromuscular performance. Finally, it is unclear if energy drinks are the optimal vehicle to deliver caffeine when high doses are needed to improve neuromuscular performance. PMID:25293550

Cancer (ICD-9: 140-208, ICD-10: C00-C97 accounted for 28% of all male deaths and for 22% of all female deaths. Cancer treatment consists on surgery, radio- and chemotherapy. During chemotherapy patients may experience a wide variety of toxic effects (including life-threatening toxicity which require treatment. The type and the intensity of chemotherapy toxicity are one of the limiting factors in cancer treatment. Toxic effects are also one of the factors affecting health related quality of life (HRQOL during chemotherapy. Mistletoe extracts belong to the group of so called „unconventional methods“ and are used in Germany as complementary cancer treatments. It has been postulated that the addition of mistletoe to chemotherapeutical regimes could help reduce chemotherapy-induced toxicity and enhance treatment tolerability. The German social health insurance covers the prescription of ML I standardized mistletoe extracts when those are prescribed as palliative cancer treatments with the aim of improving HRQOL. Research questions: * Does the addition of mistletoe to chemotherapeutical regimes reduce their toxicity? * Does the addition of mistletoe to chemotherapeutical regimes contribute to improve quality of life? * Has the addition of mistletoe to chemotherapeutical regimes any effects on survival? * Has the addition of mistletoe to chemotherapeutical regimes any effects on tumor-remission?

    A comparative assessment of the effectiveness of different prophylactic procedures to prevent the adverse effects of weightlessness is presented. It is concluded that: physical training is most effective but no single method by itself produces the full effect, and an adjustment of regimes to one another enhances the effect. The approved complex of prophylactic procedures affected basic changes occurring in hypokinesia: deficit of muscular activity, no or reduced BP hydrostatic component, reduced volume of blood circulation, reduced hydration level, and the application of various prophylactic complexes during 49 day antiorthostatic hypodynamia eliminated or reduced the adverse effects of weightlessness in simulation.

  14. Side effects of iodine prophylaxis in pregnant rats (experimental studies)

    International Nuclear Information System (INIS)

    The embryotoxic effect of single treatment of rats with potassium iodide was studied. The dose being used provided thyroid protecting parameters, comparable to those of the dose adapted for iodine prophylaxis of adults in Bulgaria. The embryotoxic effect of a combination of a much lower dose of potassium iodide with potassium perchlorate was also studied. Data for selected days of the first half of rat pregnancy, corresponding to the first phase of pituitary-hypothalamo-thyroid system development, were presented. The parameters being studied on prenatal damage, including visible malformations of the central nervous system and the extremities, as well as changes in the fetal body mass, showed no deviations from those in the respective controls. In comparison with the authors' results of previous studies showing embryotoxicity of repeated treatment, the single treatment at this early stage of the study might be considered harmless. 2 tabs. 8 refs

    2015-01-01

    Second-generation antipsychotics (SGAs) are increasingly being used to treat children for a range of mental health conditions, for example, anxiety disorder, attention deficit hyperactivity disorder and bipolar disorder. SGA treatment is associated with weight gain and cardiometabolic side effects such as dyslipidemia, insulin resistance and elevated blood pressure, in some, but not all children. This review provides an overview of the potential role of pharmacogenomics in predisposing a child to unhealthy weight gain and cardiometabolic side effects with SGA treatment. Specifically, the review includes a synopsis of the evidence for cardiometabolic side effects in SGA-treated children, illustrating the extent and depth of the problem; summarizes the potential long-term consequences of developing cardiometabolic risk during childhood and highlights genetic variants that may be useful in predicting cardiometabolic side effects in SGA-treated children.

    Although dexamethasone is an effective treatment for acute lymphoblastic leukemia (ALL), it can induce a variety of serious neurobehavioral side effects. We hypothesized that these side effects are influenced by glucocorticoid sensitivity at the tissue level. We therefore prospectively studied whether we could predict the occurrence of these side effects using the very low-dose dexamethasone suppression test (DST) or by measuring trough levels of dexamethasone. Fifty pediatric patients (3-16 years of age) with acute lymphoblastic leukemia (ALL) were initially included during the maintenance phase (with dexamethasone) of the Dutch ALL treatment protocol. As a marker of glucocorticoid sensitivity, the salivary very low-dose DST was used. A post-dexamethasone cortisol level predictive values of the DST for psychosocial problems and sleeping problems were 50% and 30%, respectively. Dexamethasone levels were not associated with neurobehavioral side effects. We conclude that neither the very low-dose DST nor measuring dexamethasone trough levels can accurately predict dexamethasone-induced neurobehavioral side effects. However, patients with glucocorticoid hypersensitivity experienced significantly more symptoms associated with dexamethasone-induced depression. Future studies should elucidate further the mechanisms by which neurobehavioral side effects are influenced by glucocorticoid sensitivity. PMID:27448086

    Progestins are a broad class of progestational agents widely differing in their chemical structures and pharmacological properties. Despite emerging data suggest that progestins, besides their action as endometrial protection, can also have multiple nonreproductive functions, much remains to be discovered regarding the actions exerted by these molecules in the nervous system. Here, we report the role exerted by different progestins, currently used for contraception or in postmenopausal hormone replacement therapies, in regulating cognitive functions as well as social behavior and mood. We provide evidence that the effects and mechanisms underlying their actions are still confusing due to the use of different estrogens and progestins as well as different doses, duration of exposure, route of administration, baseline hormonal status and age of treated women. We also discuss the emerging issue concerning the relevant increase of these substances in the environment, able to deeply affect aquatic wildlife as well as to exert a possible influence in humans, which may be exposed to these compounds via contaminated drinking water and seafood. Finally, we report literature data showing the neurobiological action of progestins and in particular their importance during neurodegenerative events. This is extremely interesting, since some of the progestins currently used in clinical practice exert neuroprotective and anti-inflammatory effects in the nervous system, opening new promising opportunities for the use of these molecules as therapeutic agents for trauma and neurodegenerative disorders.

    Previous research suggests a link between gonadal hormones and eating disorder symptomatology. This study examined the role of gonadal hormones and hormonal sensitivity in eating disorder (ED) symptoms by using oral contraceptive (OC) side effect history as an indicator of hormonal sensitivity. A questionnaire containing two scales of the Eating Disorder Inventory-2 and an OC side effect scale was completed by 174 healthy women who had used OCs. Histories of emotional and physical OC side effects were evaluated as predictors of body dissatisfaction and drive for thinness. Women with a history of negative OC side effects had higher levels of ED symptoms. After controlling for body mass index (BMI) and depression scores, OC side effect history remained a significant predictor of body dissatisfaction and drive for thinness. The experience of OC side effects may indicate a greater risk for increased eating disorder symptoms. The findings provide further support for a hormonal link to ED symptoms, as women who are more "sensitive" to exogenous gonadal hormones also experience more ED symptoms. PMID:21725835

    The readout proportional chambers of the HPC electromagnetic calorimeter in the DELPHI experiment are affected by large ageing. In order to study the long-term behaviour fo the calorimeter, one HPC module was extracted from DELPHI in 1992 and was brought to a test area where it was artificially aged during a period of two years; an ageing level exceeding the one expected for the HPC at the end of the LEP era was reached. During this period the performance of the module was periodically tested by means of dedicated beam tests whose results are discussed in this paper. These show that ageing has no significant effects on the response linearity and on the energy resolution for electromagnetic showers, once the analog response loss is compensated for by increasing the chamber gain through the anode voltage.

  8. Adverse Effects of Synthetic Cannabinoids: Management of Acute Toxicity and Withdrawal.

    Although several chemical structural classes of synthetic cannabinoids (SCs) were recently classified as Schedule I substances, rates of use and cases of serious toxic effects remain high. While case reports and media bring attention to severe SC toxicity, daily SC use resulting in dependence and withdrawal is a significant concern that is often overlooked when discussing the risks of these drugs. There is a rich literature on evidence-based approaches to treating substance use disorders associated with most abused drugs, yet little has been published regarding how to best treat symptoms related to SC dependence given its recency as an emerging clinically significant issue. This review provides a background of the pharmacology of SCs, recent findings of adverse effects associated with both acute intoxication and withdrawal as a consequence of daily use, and treatment approaches that have been implemented to address these issues, with an emphasis on pharmacotherapies for managing detoxification. In order to determine prevalence of use in cannabis smokers, a population at high risk for SC use, we obtained data on demographics of SC users, frequency of use, and adverse effects over a 3.5-year period (2012-2015) in the New York City metropolitan area, a region with a recent history of high SC use. While controlled studies on the physiological and behavioral effects of SCs are lacking, it is clear that risks associated with using these drugs pertain not only to the unpredictable and severe nature of acute intoxication but also to the effects of long-term, chronic use. Recent reports in the literature parallel findings from our survey, indicating that there is a subset of people who use SCs daily. Although withdrawal has not been systematically characterized and effective treatments have yet to be elucidated, some symptom relief has been reported with benzodiazepines and the atypical antipsychotic, quetiapine. Given the continued use and abuse of SCs, empirical studies

    In an effort to address climate change, governments have pursued policies that seek to reduce greenhouse gases. Alternative energy, including wind power, has been proposed by some as the preferred approach. Few would debate the need to reduce air pollution, but the means of achieving this reduction is important not only for efficiency but also for health protection. The topic of adverse health effects in the environs of industrial wind turbines (AHE/IWT) has proven to be controversial and can present physicians with challenges regarding the management of an exposure to IWT. Rural physicians in particular must be aware of the possibility of people presenting to their practices with a variety of sometimes confusing complaints. An earlier version of the diagnostic criteria for AHE/IWT was published in August 2011. A revised case definition and a model for a study to establish a confirmed diagnosis is proposed.

    Malnutrition and starvation's possible adverse impacts on bone health and bone quality first came into the spotlight after the horrors of the Holocaust and the ghettos of World War II. Famine and food restrictions led to a mean caloric intake of 200-800 calories a day in the ghettos and concentration camps, resulting in catabolysis and starvation of the inhabitants and prisoners. Severely increased risks of fracture, poor bone mineral density, and decreased cortical strength were noted in several case series and descriptive reports addressing the medical issues of these individuals. A severe effect of severely diminished food intake and frequently concomitant calcium- and Vitamin D deficiencies was subsequently proven in both animal models and the most common cause of starvation in developed countries is anorexia nervosa.

    Full Text Available We present a case of complete heart block (CHB in a 58-year-old female patient with acute myeloid leukemia (AML with no past history of cardiac disease, who received caspofungin in the treatment of disseminated fungal infection. To our knowledge, this is the first case of CHB associated with caspofungins. Subsequent to induction chemotherapy the patient developed invasive pulmonary aspergillosis with sudden tachypnea, dyspnoea, fever, bilateral pulmonary infiltrates and acute respiratory insufficiency consequent to neutropenia with ANC<500. During the first dose of antifungal therapy with caspofungins, she developed complete atrioventricular block and cardiac arrest. Complete heart block is an unusual adverse effect of caspofungins which has not been reported previously. Caspofungins release histamine in peripheral blood cells, so possible histamine-mediated symptoms ranging from severe fatal anaphylaxis can occur. These data suggest that infusion-related reactions associated with caspofungin may be mediated by histamine release secondary to caspofungin therapy.

    Childhood adversity and genetic variant ADH1B-rs1229984 have each been shown to influence heavy alcohol consumption and disorders. However, little is known about how these factors jointly influence these outcomes. We assessed the main and additive interactive effects of childhood adversity (abuse, neglect, parental divorce) and the ADH1B-rs1229984 on the quantitative phenotypes “maximum drinks in a day” (Maxdrinks) and DSM-Alcohol Use Disorder (AUD) severity, adjusting for demographic variabl...

    We consider a continuous-time quantum walk on a triple graph and investigate the influence of the side chain on propagation in the main chain. Calculating the interchange of the probabilities between the two parts of the main chain, we find that a switching effect appears if there is an odd number of points in the side chain when concrete conditions between the length of the main chain and the position of the side chain are satisfied. However, such an effect does not occur if there is an even number of points in the side chain. We also suggest two proposals for experiments to demonstrate this effect, which may be employed to design a new type of switching device.

    Worldwide, the benefits of combined antiretroviral (ARV) therapy in morbidity and mortality due to perinatally acquired human immunodeficiency virus infection are beyond question and outweigh the toxicity these drugs have been associated with in HIV-infected children and adolescents to date. In puberty, abnormal body fat distribution is stigmatizating and leads to low adherence to ARV treatment. The other metabolic comorbidities (mitochondrial toxicity, dyslipidemias, insulin resistance and low bone mineral density) and renal toxicity, albeit nonsymptomatic in most children, are increasingly being reported and potentially put this population at risk for early cardiovascular or cerebrovascular atherosclerotic disease, diabetes, pathologic fractures or premature renal failure in the third and fourth decades of life. Evidence from available studies is limited because of methodological limitations and also because of several HIV-unrelated factors influencing, to some degree, the development of these conditions. Current recommendations for the prevention, diagnosis, monitoring and treatment of metabolic and renal adverse effects in HIV-children and adolescents are based on adult studies, observational pediatric studies and experts' consensus. Healthy lifestyle habits (regarding diet, exercise and refraining from toxic substances) and wise use of ARV options are the only preventive tools for the majority of patients. Should abnormal findings arise, switches in one or more ARV drugs have proved useful. Specific therapies are also available for some of these comorbidities, although the experience in the pediatric age is still very scarce. We aim to summarize the epidemiological, clinical and therapeutic aspects of metabolic and renal adverse effects in vertically HIV-infected children and adolescents. PMID:25629891

  16. Serious adverse effects of gamma knife radiosurgery for mesial temporal lobe epilepsy

    International Nuclear Information System (INIS)

    Gamma knife radiosurgery (GKRS) for mesial temporal lobe epilepsy (MTLE) has been proposed as an alternative to surgical resection. We report serious adverse effects of the treatment after follow-up periods over 9 years in 11 patients treated with GKRS between 1997 and 2000. The target volume of the entorhinoamygdalohippocampectomy area was 4.8-17.1 ml. Marginal dose of 20-25 Gy to the 50% isodose was delivered. One patient was drowned after suffering seizure 7 months after GKRS. Two patients did not show any reduction in seizure frequency over 9 and 18 months. Both patients requested open surgery and became seizure-free postoperatively. Four of the other eight patients were classified as Engel's class I within 4 years after GKRS. One of the four patients experienced symptomatic radiation-induced cerebral edema transiently, one developed radiation necrosis and required surgery 5 years after GKRS, and one developed cognitive impairment with hemiparesis 10 years after GKRS. Magnetic resonance (MR) imaging showed a large cyst in the irradiated temporal lobe. This patient recovered fully after the cyst excision. Only one patient became seizure-free and antiepileptic drug-free without symptomatic radiation-induced complications. However, MR imaging revealed abnormal enhancement, cyst formation, and diffuse white matter change in the irradiated temporal lobe 9 years after GKRS. GKRS for MTLE causes adverse effects of delayed seizure remission and symptomatic radiation-induced complications. Therefore, GKRS cannot be considered as an ideal alternative to surgery for MTLE. Long-term follow-up studies including MR imaging with contrast medium are required for the patients even after successful control of seizures. (author)

  17. Adverse effects of radon and its progeny on immune system in rats

    International Nuclear Information System (INIS)

    Objective: To study adverse effects of inhaled radon and its progeny on immune system of rats. Methods: Sprague-Dawley rats were exposed to radon and its progeny at cumulative doses up to 66, 111 and 174 WLM (working level month), respectively. The numbers and types of cells in bronchoalveolar lavage fluids (BALF) were investigated. The spleen index was examined. The DNA migration in the thymus and spleen cells was detected with single cell gel electrophoresis(SCGE). RT-PCR was applied to determine the expression of IL-6 mRNA in BALF cells. Results: It was shown that the proportion of lymphocyte of the exposed groups was significantly lower than that of the control group while the proportion of granulocyte was higher than that of the control group (P<0.05). The distance of DNA migration in the thymus and spleen cells increased in the 174 WLM group. The spleen index of 111 WLM and 174 WLM groups decreased significantly compared with the control group. A high expression level of IL-6 mRNA in BALF cells was observed in the 174 WLM group (P<0.01) but there was no significant change in other two exposed groups compared with the control group. Conclusion: The results suggest that in certain dose range radon and its progeny have adverse effect on structure and function of immune system of rats by affecting the proportion of lymphocyte and granulocyte in BALF, decreasing spleen index, and damaging the DNA of the thymus and spleen cells.

    Little is known about the health impact of air pollution on children's cardiovascular health. A cross-sectional study was conducted and data was analysed in 2048 Chinese schoolchildren (aged 8-10 years) in three districts of Hong Kong to examine the association between exposure to outdoor air pollution and cardiorespiratory fitness. Annual means of ambient PM10, SO2, NO2 and O3 from 1996 to 2003 were used to estimate individual exposure of the subjects. Cardiorespiratory fitness was measured for maximal oxygen uptake (VO2max), predicted by the multistage fitness test (MFT). Height and weight were measured and other potential confounders were collected with questionnaires. Analysis of covariance was performed to estimate the impact of air pollution on complete speed in the MFT and predicted VO2max. The results showed that children in high-pollution district had significantly lower complete speed and predicted VO2max compared to those in low- and moderate-pollution districts. Complete speed and predicted VO2max was estimated to reduce 0.327 km h-1 and 1.53 ml kg-1 min-1 per 10 μg m-3 increase in PM10 annual mean respectively, with those in girls being greater than in boys. Being physically active could not significantly result in improved cardiorespiratory fitness in polluted districts. The adverse effect seems to be independent of short-term exposure to air pollution. We concluded that long-term exposure to higher outdoor air pollution levels was negatively associated with cardiorespiratory fitness in Chinese schoolchildren, especially for girls. PM10 is the most relevant pollutant of the adverse effect. Elevated cardiorespiratory fitness observed in physically activate children could be negated by increased amount of inhaled pollutants during exercise.

    Cannabinoids (the active constituents of Cannabis sativa) and their derivatives have got intense attention during recent years because of their extensive pharmacological properties. Cannabinoids first developed as successful agents for alleviating chemotherapy associated nausea and vomiting. Recent investigations revealed that cannabinoids have a wide range of therapeutic effects such as appetite stimulation, inhibition of nausea and emesis, suppression of chemotherapy or radiotherapy-associated bone loss, chemotherapy-induced nephrotoxicity and cardiotoxicity, pain relief, mood amelioration, and last but not the least relief from insomnia. In this exploratory review, we scrutinize the potential of cannabinoids to counteract chemotherapy-induced side effects. Moreover, some novel and yet important pharmacological aspects of cannabinoids such as antitumoral effects will be discussed. PMID:25504799

  20. Side effects of oxysterols: cytotoxicity, oxidation, inflammation, and phospholipidosis

    Full Text Available Oxysterols are 27-carbon atom molecules resulting from autoxidation or enzymatic oxidation of cholesterol. They are present in numerous foodstuffs and have been demonstrated to be present at increased levels in the plasma of patients with cardiovascular diseases and in atherosclerotic lesions. Thus, their role in lipid disorders is widely suspected, and they might also be involved in important degenerative diseases such as Alzheimer's disease, osteoporosis, and age-related macular degeneration. Since atherosclerosis is associated with the presence of apoptotic cells and with oxidative and inflammatory processes, the ability of some oxysterols, especially 7-ketocholesterol and 7β-hydroxycholesterol, to trigger cell death, activate inflammation, and modulate lipid homeostasis is being extensively studied, especially in vitro. Thus, since there are a number of essential considerations regarding the physiological/pathophysiological functions and activities of the different oxysterols, it is important to determine their biological activities and identify their signaling pathways, when they are used either alone or as mixtures. Oxysterols may have cytotoxic, oxidative, and/or inflammatory effects, or none whatsoever. Moreover, a substantial accumulation of polar lipids in cytoplasmic multilamellar structures has been observed with cytotoxic oxysterols, suggesting that cytotoxic oxysterols are potent inducers of phospholipidosis. This basic knowledge about oxysterols contributes to a better understanding of the associated pathologies and may lead to new treatments and new drugs. Since oxysterols have a number of biological activities, and as oxysterol-induced cell death is assumed to take part in degenerative pathologies, the present review will focus on the cytotoxic activities of these compounds, the corresponding cell death signaling pathways, and associated events (oxidation, inflammation, and phospholipidosis.

  1. DRD4-exonIII-VNTR moderates the effect of childhood adversities on emotional resilience in young-adults.

    Debjani Das

    Full Text Available Most individuals successfully maintain psychological well-being even when exposed to trauma or adversity. Emotional resilience or the ability to thrive in the face of adversity is determined by complex interactions between genetic makeup, previous exposure to stress, personality, coping style, availability of social support, etc. Recent studies have demonstrated that childhood trauma diminishes resilience in adults and affects mental health. The Dopamine receptor D4 (DRD4 exon III variable number tandem repeat (VNTR polymorphism was reported to moderate the impact of adverse childhood environment on behaviour, mood and other health-related outcomes. In this study we investigated whether DRD4-exIII-VNTR genotype moderates the effect of childhood adversities (CA on resilience. In a representative population sample (n = 1148 aged 30-34 years, we observed an interactive effect of DRD4 genotype and CA (β = 0.132; p = 0.003 on resilience despite no main effect of the genotype when effects of age, gender and education were controlled for. The 7-repeat allele appears to protect against the adverse effect of CA since the decline in resilience associated with increased adversity was evident only in individuals without the 7-repeat allele. Resilience was also significantly associated with approach-/avoidance-related personality measures (behavioural inhibition/activation system; BIS/BAS measures and an interactive effect of DRD4-exIII-VNTR genotype and CA on BAS was observed. Hence it is possible that approach-related personality traits could be mediating the effect of the DRD4 gene and childhood environment interaction on resilience such that when stressors are present, the 7-repeat allele influences the development of personality in a way that provides protection against adverse outcomes.

  2. USE OF HEMATOPOIETIC GROWTH FACTOR IN THE MANAGEMENT OF HEMATOLOGICAL SIDE EFFECTS ASSOCIATED TO ANTIVIRAL TREATMENT FOR HCV HEPATITIS

    Full Text Available Haematological abnormalities are common during combination antiviral therapy for chronic hepatitis C. Although dose reduction or discontinuation can easily treat these side effects, they can adversely affect the efficacy of combination antiviral therapy reducing the likelihood of a sustained viral response (SVR. To avoid potentially diminishing a patient’s chance of response, many physicians have begun using growth factors off-label to manage anaemia and neutropenia in hepatitis C. Haematopoietic growth factors are generally well tolerated and they may be useful for managing haematological side effects of anti-HCV therapy improving patients’ quality of life. To date, the role and benefit of these agents during anti-HCV therapy and their positive impact on SVR have not conclusively determined in the published studies. However, the possibility of a benefit to individual outpatients remains, and an individualized approach is recommended. This review explores the incidence, clinical significance, and management of anaemia, neutropenia and thrombocytopenia associated with combination therapy for HCV infection.

  3. Effects of SNS activation on SSRI-induced sexual side effects differ by SSRI.

    2009-01-01

    Selective serotonin reuptake inhibitors (SSRIs) are associated with significant sexual side effects. By definition, all SSRIs increase overall serotonin (5HT) by binding to serotonin autoreceptors (5HT(IA)); however, each SSRI has a unique portfolio of secondary binding properties to other neurotransmitters such as norepinephrine (NE). As 5HT(IA) receptors mediate NE neurotransmission, SSRIs that are highly selective for 5HT(IA) are more likely to reduce NE efficiency; however, in SSRIs that are less selective for 5HT(IA), this could be counteracted by secondary binding to NE. Norepinephrine is the major neurotransmitter of the sympathetic nervous system (SNS), which has been shown to mediate genital arousal in women; thus, it is possible that increasing SNS activity in women taking SSRIs that are highly selective for 5HT(IA) may counteract sexual side effects in those women. To test this hypothesis, we conducted a reanalysis of Meston (2004)'s 8-week, double-blind, cross-over, placebo-controlled study of the effects of ephedrine (50 mg taken 1 h prior to sexual activity) on self-reported sexual functioning of women taking paroxetine (N = 5), sertraline (N = 7), or fluoxetine (N = 7). As predicted, women taking SSRIs, which are highly selective for 5HT(IA) (sertraline, paroxetine), showed improvement in sexual arousal and orgasm. By contrast, women taking SSRIs, which are less selective for 5HT(IA) relative to NE (fluoxetine), showed no change or decrease in sexual functioning. These findings have implications for treating certain SSRI-induced sexual side effects. PMID:19466669

  4. Adverse effects of cyclosporine A on HSP25, alpha B-crystallin and myofibrillar cytoskeleton in rat heart

    International Nuclear Information System (INIS)

    Cyclosporine (CsA) is a universally used immunosuppressive drug which induces adverse side effects in several organs, but its impact on the heart is still controversial. Small heat shock proteins (sHSPs), such as HSP25 and alpha B-crystallin, are cytoprotective stress proteins exceptionally represented in the heart. They act as myofibrillar chaperones that help actin and desmin to maintain their optimum configuration and stability, thereby antagonizing oxidative damage. The present study examined: (1) the cardiac distribution and abundance of HSP25 and alpha B-crystallin in rats receiving CsA at a therapeutic dosage (15 mg/kg/day) for 42 days and 63 days; (2) the presence of myofibrillar proteins, such as actin, alpha-actinin and desmin following the CsA treatments; (3) the subcellular effects of prolonged CsA exposure on the cardiomyocytes by histopathology and transmission electron microscopy. After 63 days CsA intake, sHSPs translocated from a regular sarcomeric pattern to peripheral sarcolemma and intercalated discs, together with actin and desmin. In contrast, the sarcomeric alpha-actinin pattern did not change in all experimental groups. The abundance of actin and HSP25 was unchanged in every time point of treatment while after 63 days CsA, alpha B-crystallin and desmin levels significantly decreased. Furthermore CsA induced fibrosis, irregular sarcomeric alignment and damaged desmosomes. These findings indicate that following prolonged CsA exposure, the cardiac muscle network was affected. In particular, the translocation of sHSPs to intercalated discs merits special consideration as a direct compensatory mechanism to limit CsA cardiotoxicity.

  5. Some effects of favorable and adverse electric fields on pool boiling in dielectric fluids

    International Nuclear Information System (INIS)

    The effects of the application of an electric field on pool boiling in dielectric fluids were studied in this work.Two different geometries were used: one which is favorable to the bubble detachment (favorable electric field) and other which attract the bubbles toward the heater (adverse electric field).In the favorable electric field experiments, the void fraction and impact rate were calculated from the measured indicator function.Those parameters were obtained varying the probe-heater distance and the power to the heater.The results show a reduction of the void fraction with increasing applied voltage, probably caused by the combination of the dielectrophoretic force and a smaller bubble size due to the electric field application. Also, the impact rate decreases when a voltage is applied and the heat fluxes are close to the critical heat flux (CHF).On the other hand, the impact rate increases with voltage for moderate heat fluxes.Another interesting result is the approximately exponential decay of the void fraction and impact rate with the distance to the heater. Both the void fraction and the impact rate grow with heat flux if the heat fluxes are moderate, with or without applied voltage.For highest heat fluxes the void fraction still grows with heat flux if there are no applied electric fields while decreases with heat flux when there is an applied voltage. Similar behavior is observed in the impact rate.The boiling regimes was measured with adverse electric fields using two techniques.The heat transfer in the nucleate boiling regime was measured on an electrically powered heater.The results in these experiments show a reduction in the CHF of 10 % for saturation conditions and 10 kV of applied voltage, and a reduction of up to 40 % for 20 oC of liquid subcooling.The boiling curve corresponding to the transition and film boiling was performed with quenching experiments.An increase in the heat flux was achieved when an electric field was applied in spite of the

    Research was conducted to evaluate conversations about epilepsy between community-based neurologists and patients. Adverse effects of antiepileptic drugs and mood/behavioral issues were infrequently discussed, and neurologists and patients disagreed about these issues postvisit. Follow-up research was conducted to assess the impact of a previsit assessment tool on discussions of epilepsy. Twenty neurologists reviewed a tool incorporating questions from validated instruments (Adverse Events Profile [AEP] and Neurological Disorders Depression Inventory for Epilepsy [NDDI-E]). Naturally occurring interactions between neurologists and 60 patients were recorded. Neurologists and patients were interviewed separately. All components were transcribed and analyzed using sociolinguistics. Using the previsit assessment tool increased the number of discussions about adverse effects and mood/behavioral issues and increased neurologist-patient agreement about issues postvisit. Visit length did not increase significantly when the tool was used. Ten months after follow-up research, 50% of neurologists reported continuing to use the tool in everyday practice with patients with epilepsy. PMID:21967731

    Wogonin, a flavone in the roots of Scutellaria baicalensis, reduced etoposide-induced apoptotic cell death in normal cells, such as bone marrow cells and thymocytes. On the other hand, wogonin potentiated the proapoptotic or cytotoxic action of etoposide in tumor cells, such as Jurkat, HL-60, A549, and NCI-H226. These contradictory actions of wogonin on apoptosis are distinguished by normal or cancer cell types. Wogonin had no effect on apoptosis induced by other anticancer agents in the tumor cells. Thus, the potentiation effect of wogonin was observed only in etoposide-induced apoptosis in tumor cells. In a functional assay for P-glycoprotein (P-gp), wogonin suppressed excretion of calcein, a substrate for P-gp, in these tumor cells. Moreover, wogonin decreased the excretion of radiolabeled etoposide and accordingly increased intracellular content of this agent in the cells. P-gp inhibitors showed a similar potentiation effect on etoposide-induced apoptosis in these tumor cells. Thus, wogonin is likely to potentiate the anticancer action of etoposide due to P-gp inhibition and accumulation of this agent. These findings suggest that wogonin may be a useful chemotherapeutic adjuvant to potentiate the pharmacological action of etoposide and ameliorate its adverse effects. PMID:20658136

    The cost of photovoltaic (PV) energy is reduced by increasing solar cell power conversion efficiency and decreasing manufacture cost. An effective way of lowering the cost of Si thin film solar cells (TFSC) is to grow panels on large-area substrates. In this paper we study the effect of air residual to Si TFSC grown on 5.7 m{sup 2} glass in plasma-enhanced chemical vapor deposition (PECVD) chambers. Structural and chemical analysis show that oxygen incorporated into the Si films behaved as impurity dopant in the hydrogenated microcrystalline Si ({mu}c-Si) layers and reduced the efficiency of amorphous Si (a-Si)/{mu}c-Si tandem junction solar cells when the film had oxygen concentration >2 x 10{sup 19} atoms/cm{sup 3}. Higher oxygen content further suppressed the {mu}c-Si crystallization. We found that hydrogen plasma treatment of process chamber before Si film deposition effectively reduced the adverse effects of air exposure and improved both film quality and solar cell performance. The hydrogen-treated chamber produced contamination-free, solar cells with consistent, initial efficiency >10%. (author)

    Effects of fullerene-spiked sediment on a benthic organism, Lumbriculus variegatus (Oligochaeta), were investigated. Survival, growth, reproduction, and feeding rates were measured to assess possible adverse effects of fullerene agglomerates produced by water stirring and then spiked to a natural sediment. L. variegatus were exposed to 10 and 50 mg fullerenes/kg sediment dry mass for 28 d. These concentrations did not impact worm survival or reproduction compared to the control. Feeding activities were slightly decreased for both concentrations indicating fullerenes' disruptive effect on feeding. Depuration efficiency decreased in the high concentration only. Electron and light microscopy and extraction of the worm fecal pellets revealed fullerene agglomerates in the gut tract but not absorption into gut epithelial cells. Micrographs also indicated that 16% of the epidermal cuticle fibers of the worms were not present in the 50 mg/kg exposures, which may make worms susceptible to other contaminants. - Highlights: > Effects of fullerene-spiked sediment on black worms were investigated. > Survival, growth, reproduction, and feeding rates were measured. > Exposure did not impact worm survival or reproduction. > Feeding rates and depuration efficiency were decreased. > Worms transferred fullerenes from the sediment to the sediment surface. - Exposure to fullerene-spiked sediment decreased black worms' feeding and depuration efficiency, but fullerenes did not appear to be absorbed into the microvilli.

  13. The Development of Countermeasures for Space Radiation Induced Adverse Health Effects

    The Development of Countermeasures for Space Radiation Induced Adverse Health Effects Ann R. Kennedy Department of Radiation Oncology, University of Pennsylvania School of Medicine, 195 John Morgan Building, 3620 Hamilton Walk, Philadelphia, PA, United States 19104-6072 The development of countermeasures for radiation induced adverse health effects is a lengthy process, particularly when the countermeasure/drug has not yet been evaluated in human trials. One example of a drug developed from the bench to the clinic is the soybean-derived Bowman-Birk inhibitor (BBI), which has been developed as a countermeasure for radiation induced cancer. It was originally identified as a compound/drug that could prevent the radiation induced carcinogenic process in an in vitro assay system in 1975. The first observation that BBI could inhibit carcinogenesis in animals was in 1985. BBI received Investigational New Drug (IND) Status with the U.S. Food and Drug Administration (FDA) in 1992 (after several years of negotiation with the FDA about the potential IND status of the drug), and human trials began at that time. Phase I, II and III human trials utilizing BBI have been performed under several INDs with the FDA, and an ongoing Phase III trial will be ending in the very near future. Thus, the drug has been in development for 35 years at this point, and it is still not a prescription drug on the market which is available for human use. A somewhat less time-consuming process is to evaluate compounds that are on the GRAS (Generally Recognized as Safe) list. These compounds would include some over-the-counter medications, such as antioxidant vitamins utilized in human trials at the levels for which Recommended Dietary Allowances (RDAs) have been established.

    Full Text Available Helicobacter suis (H. suis is a widespread porcine gastric pathogen, which is also of zoonotic importance. The first goal of this study was to investigate the efficacy of several vaccine adjuvants (CpG-DNA, Curdlan, Freund's Complete and Incomplete, Cholera toxin, administered either subcutaneously or intranasally along with H. suis whole-cell lysate, to protect against subsequent H. suis challenge in a BALB/c infection model. Subcutaneous immunization with Freund's complete (FC/lysate and intranasal immunization with Cholera toxin (CT/lysate were shown to be the best options for vaccination against H. suis, as determined by the amount of colonizing H. suis bacteria in the stomach, although adverse effects such as post-immunization gastritis/pseudo-pyloric metaplasia and increased mortality were observed, respectively. Therefore, we decided to test alternative strategies, including sublingual vaccine administration, to reduce the unwanted side-effects. A CCR4 antagonist that transiently inhibits the migration of regulatory T cells was also included as a new adjuvant in this second study. Results confirmed that immunization with CT (intranasally or sublingually is among the most effective vaccination protocols, but increased mortality was still observed. In the groups immunized subcutaneously with FC/lysate and CCR4 antagonist/lysate, a significant protection was observed. Compared to the FC/lysate immunized group, gastric pseudo-pyloric metaplasia was less severe or even absent in the CCR4 antagonist/lysate immunized group. In general, an inverse correlation was observed between IFN-γ, IL-4, IL-17, KC, MIP-2 and LIX mRNA expression and H. suis colonization density, whereas lower IL-10 expression levels were observed in partially protected animals.

    The use of antipsychotic drugs represents an important approach for the treatment of schizophrenia. However, their efficacy is limited to certain symptoms of this disorder, and they induce serious side effects. As a result, there is a strong demand for the development of new drugs, which depends on reliable animal models for pharmacological characterization. The present review discusses the face, construct, and predictive validity of classical animal models for studying the efficacy and side ...

    Full Text Available Background: The combination of antiretroviral therapy is the corner stone of management of patients with human immune deficiency virus infection. Although antiretroviral therapy can reduce viral load to undetectable level, improve the immunity and prolong survival of patients, antiretroviral drugs are associated with many adverse effects that may be severe and affect patient adherence and quality of life. Aims : The aim of this study was to assess management strategies under taken in patient′s experienced common adverse effects of highly active antiretroviral therapy in Goba Hospital antiretroviral clinic. Patients and Methods: A cross sectional study of patient record chart of patients who had follow-up during data collection period was done followed by patient interview. Data was filled on well structured questionnaire and analyzed using SPSS for window version 16.0. Results: The common adverse effects were Rash (48.8%, Peripheral neuropathy (36.9% and Anemia (20.24%. The rate of management was 39.3%. Pyridoxine (36.8% was commonly prescribed drug for management of Peripheral neuropathy. Chlorphenarimine gel and Iron gluconate were common drugs for management of Rash and Anemia respectively. Use of traditional healers (57.7% was leading reason for non-management. Conclusion: Rate of management for common adverse effect is low. Education should be given on adverse effects for patients.

  18. Agricultural sources of contaminants of emerging concern and adverse health effects on freshwater fish

    Agricultural contaminants of emerging concern (CECs) are generally thought of as certain classes of chemicals associated with animal feeding and production facilities. Veterinary pharmaceuticals used in animal food production systems represent one of the largest groups of CECs. In our review, we discuss the extensive increase in use of antibiotics in animal feeding operations (AFOs) around the world. AFOs are a major consumer of antibiotics and other veterinary pharmaceuticals and over the past decade there has been growing information on the occurrence, release, and fate of CECs from animal food production operations, including the application of pharmaceutical-containing manure to agricultural fields and releases from waste lagoons. Concentrations of CECs in surface and ground water in proximity to AFOs correspond to their presence in the AFO wastes. In many cases, the environmental concentrations of agriculturally-derived CECs are below toxicity thresholds. Hormones and hormone replacement compounds are a notable exception, where chemical concentrations near AFOs can exceed concentrations known to cause adverse effects on endocrine-related functions in fish. In addition, some agricultural pesticides, once thought to be safe to non-target organisms, have demonstrated endocrine-related effects that may pose threats to fish populations in agricultural regions. That is, we have pesticides with emerging concerns, thus, the concern is emerging and not necessarily the chemical. In this light, one must consider certain agricultural pesticides to be included in the list of CECs. Even though agricultural pesticides are routinely evaluated in regulatory testing schemes which have been used for decades, the potential hazards of some pesticides have only recently been emerging. Emerging concerns of pesticides in fish include interference with hormone signaling pathways; additive (or more than additive) effects from pesticide mixtures; and adverse population-level effects at

    Data sourcesMedline, Cochrane Database of Systematic Reviews, Database of Abstracts of Reviews of Effects, Cochrane Central Register of Controlled Trials, Virtual Health Library and Web of Science were systematically searched up to July 2015 without limitations. Scopus, Google Scholar, ClinicalTrials.gov, the ISRCTN registry as well as reference lists of the trials included and relevant reviews were manually searched.Study selectionRandomised (RCTs) and prospective non-randomised clinical trials (non-RCTs) on human patients that compared therapeutic and adverse effects of lingual and labial appliances were considered. One reviewer initially screened titles and subsequently two reviewers independently screened the selected abstracts and full texts.Data extraction and synthesisThe data were extracted independently by the reviewers. Missing or unclear information, ongoing trials and raw data from split-mouth trials were requested from the authors of the trials. The quality of the included trials and potential bias across studies were assessed using Cochrane's risk of bias tool and the Grading of Recommendations Assessment, Development and Evaluation (GRADE) approach. For parallel trials, mean difference (MD) and the relative risk (RR) were used for continuous (objective speech performance, subjective speech performance, intercanine width, intermolar width and sagittal anchorage loss) and binary outcomes (eating difficulty), respectively. The standardised mean difference (SMD) was chosen to pool, after conversion, the outcome (oral discomfort) that assessed both binary and continuous. Random-effects meta-analyses were conducted, followed by subgroup and sensitivity analyses.ResultsThirteen papers pertaining to 11 clinical trials (three parallel RCTs, one split-mouth RCT and seven parallel prospective non-RCTs) were included with a total of 407 (34% male/66% female) patients. All trials had at least one bias domain at high risk of bias. Compared with labial appliances

    Chemical prroducts used in farming and wastes from livestock can contaminate pond water in agroecosystems due to runoff. Amphibians using these ponds for breeding are probably exposed to pollutants, and serious consequences might be observed afterward at the population level. Assessment biological endpoints of anuran to water quality give a realistic estimate of the probability of occurrence of adverse effects and provide an early warning signal. In this study, the ecotoxicity of agroecosystem ponds from the south of Córdoba province, Argentina, was investigated. Ponds in four sites with different degrees of human disturbance were selected: three agroecosystems (A1, A2, A3) and a site without crops or livestock (SM). The effect of pond water quality on the biological endpoint of Rhinella arenarum tadpoles was examined using microcosms with pond water from sites. Biological endpoints assessed were as follows: mortality, growth, development, morphological abnormalities (in body shape, gut, and labial tooth row formula), behavior, and blood cell parameters (micronucleus and nuclear abnormalities). Results indicated that water from agroecosystems has adverse effect on early life stage of R. arenarum. High mortality and fewer metamorphs were recorded in the A1 and A3 treatments. Tadpoles and metamorphs from A1 and A2 treatments had lower body condition. Tadpoles from A1 and A3 showed the highest prevalence of morphological abnormalities. The lowest amount of tadpoles feeding and the highest percentage of tadpoles swimming on the surface were observed in treatments with agroecosystem pond water. The higher frequencies of micronuclei and nuclear abnormalities were recorded in tadpoles from A1, A2, and A3 treatments. We check the sensitivity of the biological endpoints of R. arenarum tadpoles like early warning indicators of water quality. We found that the poor water quality of agroecosystem ponds has impact on the health of the tadpoles, and this could affect the

  1. Honeybees Produce Millimolar Concentrations of Non-Neuronal Acetylcholine for Breeding: Possible Adverse Effects of Neonicotinoids

    The worldwide use of neonicotinoid pesticides has caused concern on account of their involvement in the decline of bee populations, which are key pollinators in most ecosystems. Here we describe a role of non-neuronal acetylcholine (ACh) for breeding of Apis mellifera carnica and a so far unknown effect of neonicotinoids on non-target insects. Royal jelly or larval food are produced by the hypopharyngeal gland of nursing bees and contain unusually high ACh concentrations (4–8 mM). ACh is extremely well conserved in royal jelly or brood food because of the acidic pH of 4.0. This condition protects ACh from degradation thus ensuring delivery of intact ACh to larvae. Raising the pH to ≥5.5 and applying cholinesterase reduced the content of ACh substantially (by 75–90%) in larval food. When this manipulated brood was tested in artificial larval breeding experiments, the survival rate was higher with food supplemented by 100% with ACh (6 mM) than with food not supplemented with ACh. ACh release from the hypopharyngeal gland and its content in brood food declined by 80%, when honeybee colonies were exposed for 4 weeks to high concentrations of the neonicotinoids clothianidin (100 parts per billion [ppb]) or thiacloprid (8,800 ppb). Under these conditions the secretory cells of the gland were markedly damaged and brood development was severely compromised. Even field-relevant low concentrations of thiacloprid (200 ppb) or clothianidin (1 and 10 ppb) reduced ACh level in the brood food and showed initial adverse effects on brood development. Our findings indicate a hitherto unknown target of neonicotinoids to induce adverse effects on non-neuronal ACh which should be considered when re-assessing the environmental risks of these compounds. To our knowledge this is a new biological mechanism, and we suggest that, in addition to their well documented neurotoxic effects, neonicotinoids may contribute to honeybee colony losses consecutive to a reduction of the ACh content

    Mucopolysaccharidosis type I (MPS I) is a lysosomal storage disorder characterized by diminished degradation of the glycosaminoglycans heparan sulfate (HS) and dermatan sulfate (DS). Patients present with a variety of symptoms, including severe skeletal disease. Current therapeutic strategies have only limited effects on bone disease. The isoflavone genistein has been studied as a potential therapy for the mucopolysaccharidoses because of its putative ability to inhibit GAG synthesis and subsequent accumulation. Cell, animal, and clinical studies, however, showed variable outcomes. To determine the effects of genistein on MPS I-related bone disease, wild-type (WT) and MPS I mice were fed a genistein-supplemented diet (corresponding to a dose of approximately 160 mg/kg/day) for 8 weeks. HS and DS levels in bone and plasma remained unchanged after genistein supplementation, while liver HS levels were decreased in genistein-fed MPS I mice as compared to untreated MPS I mice. Unexpectedly, genistein-fed mice exhibited significantly decreased body length and femur length. In addition, 60% of genistein-fed MPS I mice developed a scrotal hernia and/or scrotal hydrocele, manifestations, which were absent in WT or untreated MPS I mice. In contrast to studies in MPS III mice, our study in MPS I mice demonstraes no beneficial but even potential adverse effects of genistein supplementation. Our results urge for a cautious approach on the use of genistein, at least in patients with MPS I. PMID:25854773

    There is a growing body of epidemiological research reporting the neurological effects of ambient air pollution. We examined current evidence, identified the strengths and weaknesses of published epidemiological studies, and suggest future directions for research in this area. Studies were identified through a systematic search of online scientific databases, in addition to a manual search of the reference lists from the identified papers. Despite being a relatively new area of investigation, overall, there is mounting evidence implicating adverse effects of air pollution on neurobehavioral function in both adults and children. Further research is needed to expand our understanding of these relationships, including improvement in the accuracy of exposure assessments; focusing on specific toxicants and their relationships to specific health endpoints, such as neurodevelopmental disorders and neurodegenerative diseases; investigating the combined neurological effects of multiple air pollutants; and further exploration of genetic susceptibility for neurotoxicity of air pollution. In order to achieve these goals collaborative efforts are needed from multidisciplinary teams, including experts in toxicology, biostatistics, geographical science, epidemiology, and neurology.

    Inspection error has clearly been shown to have adverse effects upon the results desired from a quality assurance sampling plan. These effects upon performance measures have been well documented from a statistical point of view. However, little work has been presented to convince the QC manager of the unfavorable cost consequences resulting from inspection error. This paper develops a very general, yet easily used, mathematical cost model. The basic format of the well-known Guthrie-Johns model is used. However, it is modified as required to assess the effects of attributes sampling errors of the first and second kind. The economic results, under different yet realistic conditions, will no doubt be of interest to QC practitioners who face similar problems daily. Sampling inspection plans are optimized to minimize economic losses due to inspection error. Unfortunately, any error at all results in some economic loss which cannot be compensated for by sampling plan design; however, improvements over plans which neglect the presence of inspection error are possible. Implications for human performance betterment programs are apparent, as are trade-offs between sampling plan modification and inspection and training improvements economics.

  6. What is an adverse effect? A possible resolution of clinical and epidemiological perspectives on neurobehavioral toxicity

    International Nuclear Information System (INIS)

    The sizes of the effects observed in studies that rely on neurobehavioral endpoints are often small. Because the mean deficits implied are more modest in magnitude than are those that correspond to the clinical criteria used to diagnose 'disease', some observers dismiss them as inconsequential. Other observers argue that the mean deficits take on greater import when viewed as effects on a population rather than on individual members of the population. Several considerations germane to an effort to reconcile these perspectives are discussed: (1) the relative sensitivity of clinical diagnoses and continuously distributed scores on neurobehavioral tests as indices of adverse effect, (2) the syndromal nature of many diagnoses in pediatric neurology and neuropsychology and the implications of shifting nosology, (3) neurobehavioral test-score changes as surrogates or as prodromes for clinically significant deficits, (4) the distinction between individual risk and population risk, and (5) the tendency of the distribution of a risk factor in a population to move up and down as a whole. The clinical and epidemiological perspectives are complementary rather than incompatible

    Calcium-activated chloride channels(CaCCs) are the crucial regulators of transepithelial fluid secretion,smooth muscle contraction and sensory transduction. Recently, compelling evidence has indicated that TMEM 16A(ANO 1 or anoctamin-i ) is a bona fide calcium-acvtivated chloride channel. A few small molecule CaCCs regulators are available for functional and therapeutic studies. We screened 126 natural compounds from Chinese herbs. Screening was performed with an iodide influx assay in Fischer rat thyroid epithelial cells to coexpress ANOI and an iodide-sensitive fluorescent indicator(EYFP-HI48Q/I152L). lmperatorin, a coumarin compound, was identifled to inhibit ANOl-mediated chloride transport activated by multiple calcium-elevating agonists. The inhibitory effect is dose-dependent with IC50 ~14.63 μmol/L. Interestingly, imperatorin activated CFTR chloride channel with EC50 ~35.52 μmol/L. The adverse effects of imperatorin on CaCC and CFTR chloride channels will make it useful in pharmacological dissection of chloride transport in airway and intestinal epithelium. Further studies are required to evaluate the therapeutic effects of imperatorin on hypertension, asthma and certain tumors.

    Herbal products have been used for centuries among indigenous people to treat symptoms and illnesses. Recently, their use in Western countries has grown significantly, rivaling that of prescription medications. Currently, herbal products are used mainly for weight loss and bodybuilding purposes but also to improve well-being and symptoms of chronic diseases. Many people believe that because they are natural, they must be effective and safe; however, these beliefs are erroneous. Few herbal products have been studied in well-designed controlled trials of patients with liver or other diseases, despite testimony to the contrary. Moreover, current highly effective antiviral drugs make efforts to treat hepatitis C with herbal products redundant. Herbal products are no safer than conventional drugs and have caused liver injury severe enough to require transplantation or cause death. Furthermore, their efficacy, safety, and claims are not assessed by regulatory agencies, and there is uncertainty about their reported and unreported contents. We review the history of commonly used herbal products, as well as their purported efficacies and mechanisms and their adverse effects. PMID:25500423

    Lithotripter SWs rupture blood vessels in the kidney. This acute trauma, accompanied by a fall in renal function, can lead to significant long-term effects such as profound scarring of the kidney cortex and renal papillaea permanent loss of functional renal mass. SWL has been linked to new-onset hypertension in some patients, and recent studies suggest that multiple lithotripsies can actually alter a patient's stone disease leading to formation of stones (brushite) that are harder to break. Cavitation and shear appear to play a role in stone breakage and tissue damage. Progress in understanding these mechanisms, and the renal response to SWs, has led to practical strategies to improve treatment. Slowing the SW-rate, or initiating treatment at low kV/power both improve stone breakage and reduce the number of potentially tissue-damaging SWs needed to achieve comminution. The observation that SWs cause transient vasoconstriction in the kidney has led to studies in pigs showing that a pre-conditioning dose of low-energy SWs significantly reduces trauma from subsequent high-energy SWs. Thus, SWs can induce adverse effects in the kidney, but what we have learned about the mechanisms of SW action suggests strategies that could make lithotripsy safer and more effective.

    The titled compound is a cyclodextrin derivative in which prednisolone 21-succinate (PDsuc) is covalently bound to one of the secondary hydroxyl groups of alpha-cyclodextrin (alpha-CyD) via an ester linkage. In this study, the PDsuc-appended alpha-CyD ester conjugate (PDsuc/alpha-CyD conjugate) was intracolonically administered to rats with 2,4,6-trinitrobenzensulfonic acid-induced colitis, and its antiinflammatory and systemic adverse effects were compared with those of prednisolone (PD) alone and the PD/2-hydroxypropyl-beta-CyD complex (PD/HP-beta-CyD complex), which is a noncovalent inclusion complex. Colonic damage score, ratio of distal colon wet weight to body weight, and myeloperoxidase activity were evaluated as measures of the therapeutic effect of PD, whereas the ratio of thymus wet weight to body weight was evaluated as a measure of the side effect of PD. The local antiinflammatory activity increased in the order of PD alone approximately PDsuc/alpha-CyD conjugate keeps the local concentration in the colon at a low but constant level. The results suggest that the PDsuc/alpha-CyD conjugate can alleviate the systemic adverse effect of PD while maintaining the therapeutic activity of PD. This kind of knowledge will be useful in the rational design of steroid prodrugs for the colon-specific drug delivery system. PMID:11745769

    Trace elements play crucial role in the maintenance of genome stability in the cells. Many endogenous defense enzymes are containing trace elements such as superoxide dismutase and metalloproteins. These enzymes are contributing in the detoxification of reactive oxidative species (ROS) induced by ionizing radiation in the cells. Zinc, copper, manganese, and selenium are main trace elements that have protective roles against radiation-induced DNA damages. Trace elements in the free salt forms have protective effect against cell toxicity induced by oxidative stress, metal-complex are more active in the attenuation of ROS particularly through superoxide dismutase mimetic activity. Manganese-complexes in protection of normal cell against radiation without any protective effect on cancer cells are more interesting compounds in this topic. The aim of this paper to review the role of trace elements in protection cells against genotoxicity and side effects induced by ionizing radiation.

    Several devices and medications have been used to address poststroke spasticity. Yet, spasticity's impact on outcomes remains controversial. Using data from a cohort of 460 ischemic stroke patients, we previously published a validated multivariable regression model for predicting 3-month modified Rankin Score (mRS) as an indicator of functional outcome. Here, we tested whether including spasticity improved model fit and estimated the effect spasticity had on the outcome. Spasticity was defined by a positive response to the question "Did you have spasticity following your stroke?" on direct interview at 3 months from stroke onset. Patients who had expired by 90 days (n = 30) or did not have spasticity data available (n = 102) were excluded. Spasticity affected the 3-month functional status (β = 0.420, 95 CI = 0.194 to 0.645) after accounting for age, diabetes, leukoaraiosis, and retrospective NIHSS. Using spasticity as a covariable, the model's R (2) changed from 0.599 to 0.622. In our model, the presence of spasticity in the cohort was associated with a worsened 3-month mRS by an average of 0.4 after adjusting for known covariables. This significant adverse effect on functional outcomes adds predictive value beyond previously established factors. PMID:25147752

    INTRODUCTION: Current space suits have limited movement due to gas pressurization during exposure to the vacuum of space. Alternatively, if pressure is applied by an elastic garment vs. pneumatic garment to produce mechanical counter pressure (MCP), several advantages are possible. In this study, we investigate local microcirculatory and other effects produced with and without a prototype MCP glove and sleeve during exposure to varying levels of vacuum. METHODS: The entire arms of eight male volunteers were studied at normal ambient pressure and during 5 min exposures to -50, -100, and -150 mm Hg with and without the MCP glove and sleeve. Pressure distribution, skin microvascular flow, and temperature were measured. RESULTS: The MCP glove and sleeve generated over 200 mm Hg on the middle finger, dorsum of the hand, and the wrist. However, pressure was significantly lower on the forearm and the upper arm. Without the glove and sleeve, only two of eight subjects tolerated -100 mm Hg. Also, no subject tolerated -150 mm Hg. However, subjects tolerated all vacuum pressures wearing the glove and sleeve. Skin microvascular flow and temperature remained within control values with the glove and sleeve at a chamber pressure of -150 mm Hg. DISCUSSION: The MCP glove and sleeve counteracts adverse effects of vacuum exposures due to lower pressure differentials. Pressure levels over the hand and wrist are similar to those of the current U.S. space suit glove and sleeve, but additional development is required to increase MCP over the forearm and upper arm.

    Seven-day batch equilibrium experiments were conducted to measure the efficacy of four phosphate amendments (trisodium trimetaphosphate [TP3], dodecasodium phytate [Na-IP6], precipitated calcium phytate [Ca-IP6], and hydroxyapatite [HA]) for immobilizing Ni and U in organic-rich sediment. Using the eight-step modified Miller's sequential extraction procedure and the USEPA's Toxicity Characteristic Leaching Procedure, the effect of these amendments on the distribution of Ni and U was assessed. Relative to unamended controls, equilibrium aqueous-phase U concentrations were lower following HA and Ca-IP6 additions but higher following TP3 and Na-IP6 amendments, whereas aqueous Ni concentrations were not decreased only in the Na-IP6 amended treatment relative to the control. The poor rates of contaminant immobilization following TP3 and Na-IP6 amendments correlate with the dispersion of organic matter and organo-mineral colloids, which probably contain sorbed U and Ni. While all amendments shifted the U distribution toward more recalcitrant soil fractions, Ni was redistributed to more labile soil fractions. This study cautions that the addition of orthophosphates and organophosphates as contaminant immobilizing amendments may in fact have adverse effects, especially in high-organic soils. Particular attention is warranted at sites with mixed contaminants with varying geochemical behaviors. PMID:21712583

  17. Analysis of heavy-ion irradiation induced adverse effect on normal tissue in murine model

    International Nuclear Information System (INIS)

    The purpose of this study was to clarify the molecular mechanism of C-ion radiation induced late injury of lung and urinary bladder in normal tissue, using murine model. Exposures were conducted using horizontal carbon-12 beams with 290 MeV/u at a dose rate of approximately 3 Gy/min within the 6-cm spread-out Bragg peak (SOBP). To evaluate the effects of C-ion irradiation on lungs, pathological changes after thoracic irradiation were analyzed. To evaluate the adverse effects on the bladder, pathological evaluation were performed. The gene expression analysis were performed using total RNA derived from irradiated tissues on 6 hour after irradiation to elucidate the molecular response to irradiation. Survival assay revealed the subacute phase death by hemorrhagic pneumonitis in C3H/He and the late phase death by pulmonary fibrosis in C57BL/6J after C-ion irradiation. Microarray analysis presented the genes with strain variance after C-ion irradiation. Immunohistochemical staining of LAMP family proteins, which relates bladder contraction, in the irradiated urinary bladder were different between strains. (author)

    Full Text Available Background. Metoclopramide is a pharmacological agent frequently used in therapy against nausea and vomiting that can occur in indigestion, motion sickness, gastric ulcer, pyloric spasm and after surgery as a side effect of some anesthetics. Knowing the frequency and intensity of metoclopramide neurological side effects is essential for an efficient management of the dysfunctions it addresses. Material and method. Based on a standard questionnaire containing questions regarding metoclopramide therapy, we analyzed the answers given by 1000 patients or patient tutors in 20 open circuit pharmacies situated all over Bucharest. All subjects freely consented to participate in this study that was coordinated only by pharmacists. Results. Our study highlights the fact that in certain situations having to do with the age of patients, with the use of multiple drugs or with the tendency to self medicate, the neurological side effects of metoclopramide can reach dangerous levels. In some cases it might even be necessary to immediately interrupt metoclopramide therapy, despite its positive benefit/ risk ratio. Conclusions. Respecting the physician’s recommendations, avoiding self medication and reporting side effects as quickly as possible, are essential elements for minimizing the consequences of metoclopramide side effects.

    It has been suggested that side preferences in spontaneous rotational behavior are determinant of differences in vulnerability to the effects of the learned helplessness paradigm. The purpose of the present study was to investigate the effects of side preferences of rotational behavior in another animal model of depression, the forced swimming test. Immobility was also investigated upon repeated testing sessions and in interaction with sex. Swiss mice (69 males and 73 females) were submitted to three sessions (test time = 5 min) of forced swimming. Immobile and turning behaviors were measured for each session and within each testing session. Consistency of laterality was defined considering the persistence of the same side turning preference in the three sessions. In general, there was an increase in immobility as test progressed and upon repeated testing sessions. Marked interindividual differences in mice immobile behavior were observed when consistency of laterality was considered. Consistent-right-turners presented greater immobility in the first session and better test-retest reliability, indicating that for this group, the adoption of immobile behavior was faster and more reliable over time. Immobility was higher for side-consistent males than for side-consistent females in the first session. This difference became even greater when consistent-right-turner males were compared to consistent-left-turner females. These results reinforce the idea that side preferences of spontaneous rotational behavior may account for interindividual differences in animal models of depression. PMID:11853109

  20. Adverse health effects due to arsenic exposure: Modification by dietary supplementation of jaggery in mice

    International Nuclear Information System (INIS)

    Populations of villages of eastern India and Bangladesh and many other parts of the world are exposed to arsenic mainly through drinking water. Due to non-availability of safe drinking water they are compelled to depend on arsenic-contaminated water. Generally, poverty level is high in those areas and situation is compounded by the lack of proper nutrition. The hypothesis that the deleterious health effects of arsenic can be prevented by modification of dietary factors with the availability of an affordable and indigenous functional food jaggery (sugarcane juice) has been tested in the present study. Jaggery contains polyphenols, vitamin C, carotene and other biologically active components. Arsenic as sodium-m-arsenite at low (0.05 ppm) and high (5 ppm) doses was orally administered to Swiss male albino mice, alone and in combination with jaggery feeding (250 mg/mice), consecutively for 180 days. The serum levels of total antioxidant, glutathione peroxidase and glutathione reductase were substantially reduced in arsenic-exposed groups, while supplementation of jaggery enhanced their levels in combined treatment groups. The serum levels of interleukin-1β, interleukin-6 and TNF-α were significantly increased in arsenic-exposed groups, while in the arsenic-exposed and jaggery supplemented groups their levels were normal. The comet assay in bone marrow cells showed the genotoxic effects of arsenic, whereas combination with jaggery feeding lessened the DNA damage. Histopathologically, the lung of arsenic-exposed mice showed the necrosis and degenerative changes in bronchiolar epithelium with emphysema and thickening of alveolar septa which was effectively antagonized by jaggery feeding. These results demonstrate that jaggery, a natural functional food, effectively antagonizes many of the adverse effects of arsenic.
