In a prospective study lumbar iohexol myelography was performed in 107 consecutive patients, randomised for lumbar puncture with a Quincke or Whitacre spinal needle. All patients answered a questionnaire about possible side effects. Data from 100 patients (58 men, 42 women) were evaluated. In the Quincke group (n = 53), 23 (43%) reported no side effects. In the 30 patients who reported various side effects, post-dural puncture headache (PDPH) occurred in 22 (42%), of whom 9 had mild, 6 moderate and 7 (13%) severe cephalalgia, 18 (34%) reported increased low back pain/sciatica, 5 nausea and 7 dizziness. In the Whitacre group (n = 47), 33 (70%) had no side effects. PDPH was reported by 9 patients (19%), of whom 2 had mild, 6 moderate and only 1 (2%) severe cephalalgia, 4 (9%) reported increased low back pain/sciatica, 5 nausea and 4 dizziness. The conclusion drawn from this study is that lumbar myelography performed with the Whitacre spinal needle reduces postspinal side effects.

Drop-out is a core problem in opioid maintenance treatment (OMT), but patients' reactions to and acceptance of the various OMT medications are insufficiently investigated. In Norway, there has been vocal patient resistance to the newest medication, buprenorphine-naloxone (BNX), and complaints have focused on the side effect profile. There has been no comparison of patient satisfaction and side effects of the three most common OMT medications. To compare patient satisfaction with OMT and side effects of BNX, buprenorphine monopreparate (BUP), and methadone (MET) as reported by patients. Data were drawn from a national peer-to-peer survey developed by a patient advocacy group. The survey engaged more than 1000 OMT patients, corresponding to one seventh of OMT patients in Norway. The associations between side effects, treatment satisfaction, and patient characteristics were tested in multinomial logistic regressions. High patient satisfaction with OMT overall was reported despite lower satisfaction with medication itself and widely prevalent side effects. Among each medication group, dissatisfaction with medications or OMT in general along with poor health status increased the relative risk ratio of reporting the heaviest side effect burden. MET users reported the highest side effect burden and BNX users the lightest, but BNX users were more dissatisfied with their medication. Side effects are a concern for nearly all OMT patients, and they do not appear to accumulate with age or length of treatment. BNX users' dissatisfaction with their medication is of particular concern, and expectations and preferences of medication may be influencing their dissatisfaction. Copyright © 2018.

There is no cure for Duchenne Muscular Dystrophy (DMD); treatment is symptomatic and corticosteroids slow the progression. Side effects of corticosteroids - especially the physical effects - have been described, however patients' and caregivers perception on chronic corticosteroid treatment and their side effects is less well known, in particular with regards to cognition, behaviour, and emotional functioning. The primary aim of this pilot study was to (i) construct a self-report questionnaire to assess the perceived benefits and side effects of corticosteroids for patients with DMD and their parents. Furthermore we aimed to (ii) investigate the psychometric qualities of this questionnaire, (iii) whether there was a difference between parents' and patient's perceptions, and finally (iv) to what extent reported side effects may alter over time. A 23-item questionnaire (SIDECORT: side effect of corticosteroids) was constructed to assess the perception of these benefits and side effects in a systematic manner. In total, 86 patients (aged 5 - 28 years) and 125 of their parents completed the questionnaire. Internal consistency was good. Using factor analyses on the side effect items as reported by parents, two underlying factors were found, with the first factor describing cognitive, behavioural and emotional functioning, and the second factor describing physical functioning. The potential benefits of corticosteroids were highly rated among both parents and patients, although parents rated the importance of the benefits higher than their sons (p = 0.002). Similarly, parents rated the severity of the side effects generally higher than their sons (p = 0.011), especially with regards to the physical side effects (p = 0.014). Based on the parent's perception, the neurodevelopmental side effects generally appeared to decline the longer corticosteroids were used. To our knowledge, this is the first explicit study on perceived cognitive-, behavioural-, and emotional side effects and the allocation of benefits to corticosteroids in DMD. On the basis of our research we suggest a short form questionnaire, which proves to be reliable and valid for research- and clinical practice. This questionnaire could provide useful insights for the care of boys and men with DMD.

To explore the actions cancer patients reported they would take in response to a range of common side effects of chemotherapy and whether these were considered appropriate based on current guidelines and evidence; and to explore the sociodemographic and cancer-related variables associated with patients selecting the appropriate action (immediate medical attention or reporting) for two potentially life-threatening side effects: fever, and unusual bleeding and bruising. Four hundred thirty-six medical oncology and haematology patients receiving chemotherapy completed two surveys to provide demographic, disease and treatment characteristics, and details on how they would respond if they experienced a range of specified side effects of chemotherapy (for example, nausea and vomiting, fatigue, and skin rash or nail changes). The proportion of patients reporting the appropriate action for each side effect was calculated. Multiple logistic regressions examined the patient demographic and cancer characteristics associated with selecting the appropriate action (seeking immediate medical attention) for two potentially life-threatening side effects of chemotherapy: high fever of 38 °C or more, and unusual bleeding or bruising. Two thirds of patients indicated that they would seek immediate medical attention for high fever (67%), but only 41% would seek immediate attention for bleeding or bruising. Cancer type and time since diagnosis were significantly associated with patients indicating that they would seek immediate medical attention for high fever; while time since diagnosis was the only variable significantly associated with patients reporting that they would seek immediate medical attention for unusual bleeding or bruising. For chronic side effects, like skin rash or nail changes, and tingling or numbness, which usually do not require urgent reporting, only between 12 and 16% would report them immediately. A significant proportion of patients reported that they would "do nothing" about fatigue or tiredness (24%). By comparison, less than 10% patients reported that they would do nothing for the other side effects investigated. Tools need to be created so that patients better understand the side effects after being treated with chemotherapy and what action they should take.

Negative physiological stimulation and sedation side effects are experienced by a significant proportion of consumers who consume alcohol mixed with energy drinks (AmED). Few studies have compared the frequency of side effects between sessions of AmED and sessions of alcohol only within-subject, and none have explored a dose relationship. Explore the occurrence of self-reported physiological stimulant and sedative side effects between sessions of AmED and alcohol only, and at varying ED dosage levels within AmED sessions. A convenience sample of 2953 residents of New South Wales, Australia completed an online survey. N=731 AmED users reported daily caffeine intake, typical alcohol and AmED consumption, and past 12-month experience of physiological stimulation and sedation side effects during AmED and alcohol only sessions. Within-subject analyses compared occurrence of side effects between session types. Hierarchical binary logistic regression analyses explored the association of ED dose during AmED sessions with the experience of physiological side effects. There were greater odds of most stimulant side effects, and lower odds of sedation side effects, during AmED sessions compared to alcohol only sessions. Compared to one ED, consumption of three or more EDs was significantly associated with the majority of both stimulant and alcohol intoxication side effects after controlling for demographics and consumption covariates. AmED is associated with perceived changes in physiological stimulant and sedation side effects of alcohol. Experience of side effects is positively associated with ED dosage. Future research should account for varying ED dosage, and reflect real world consumption levels. Copyright © 2017 Elsevier Ltd. All rights reserved.

Central nervous system side effects associated with zolpidem treatment.

2000-01-01

Zolpidem is one of the newer medications developed for the treatment of insomnia. It is an imidazopyridine agent that is an alternative to the typical sedative-hypnotic agents. Zolpidem use is gaining favor because of its efficacy and its side effect profile, which is milder and less problematic than that of the benzodiazepines and barbiturates used to treat insomnia. Still, side effects are not uncommon with zolpidem use. We report a series of cases in which the patients developed delirium, nightmares and hallucinations during treatment with zolpidem. We will review its pharmacology, discuss previous reports of central nervous system side effects, examine the impact of drug interactions with concurrent use of antidepressants, examine gender differences in susceptibility to side effects, and explore the significance of protein binding in producing side effects.

Oral health impacts of medications used to treat mental illness.

Many psychotropic medications affect oral health. This review identified oral side effects for antidepressant, antipsychotic, anticonvulsant, antianxiety and sedative drugs that are recommended in Australia for the management of common mental illnesses and provides recommendations to manage these side-effects. The Australian Therapeutic Guidelines and the Australian Medicines Handbook were searched for medications used to treat common mental health conditions. For each medication, the generic name, class, and drug company reported side-effects were extracted from the online Monthly Index of Medical Specialties (eMIMs) and UpToDate databases. Meyler's Side Effect of Drugs Encyclopaedia was used to identify additional oral adverse reactions to these medications. Fifty-seven drugs were identified: 23 antidepressants, 22 antipsychotics or mood stabilisers, and 12 anxiolytic or sedative medications. Xerostomia (91%) the most commonly reported side effect among all classes of medications of the 28 identified symptoms. Other commonly reported adverse effects included dysguesia (65%) for antidepressants, and tardive dyskinesia (94%) or increased salivation (78%) for antipsychotic medications. While xerostomia has often been reported as a common adverse effect of psychotropic drugs, this review has identified additional side effects including dysguesia from antidepressants and tardive dyskinesia and increased salivation from antipsychotics. Clinicians should consider oral consequences of psychotropic medication in addition to other side-effects when prescribing. For antidepressants, this would mean choosing duloxetine, agomelatine and any of the serotonin re-uptake inhibitors except sertraline. In the case of antipsychotics and mood stabilisers, atypical agents have less oral side effects than older alternatives. Copyright © 2017 Elsevier B.V. All rights reserved.

Effectiveness and side-effect profile data on pharmacotherapy for daytime sleepiness in central hypersomnias are based largely upon randomized controlled trials. Evidence regarding the use of combination therapy is scant. The aim of this study was to examine the effectiveness and occurrence of drug-related side effects of these drugs in routine clinical practice. Adult patients diagnosed with a central hypersomnia during a 54-month period at a tertiary sleep disorders centre were identified retrospectively. Side effects were recorded at every follow-up visit. A total of 126 patients, with 3275 patient-months of drug exposure, were categorized into narcolepsy type 1 (n = 70), narcolepsy type 2 (n = 47) and idiopathic hypersomnia (n = 9). Modafinil was the most common drug used as a first-line treatment (93%) and in combination therapy (70%). Thirty-nine per cent of the patients demonstrated a complete, 25% partial and 36% a poor response to treatment. Combination treatment improved daytime sleepiness in 55% of the patients with residual symptoms despite monotherapy. Sixty per cent of patients reported side effects, and 30% reported treatment-limiting side effects. Drugs had similar side-effect incidence (P = 0.363) and their side-effect profile met those reported in the literature. Twenty-seven per cent of the patients received combination treatment and had fewer side effects compared to monotherapy (29.4% versus 60%, respectively, P = 0.001). Monotherapy appears to achieve satisfactory symptom control in most patients with central hypersomnia, but significant side effects are common. Combination therapy appears to be a useful and safe option in patients with refractory symptoms. © 2017 European Sleep Research Society.

Psychiatric side effects of antihypertensive drugs other than reserpine.

The psychiatric side effects of the major antihypertensive drugs other than reserpine are reviewed, including centrally acting drugs such as methyldopa and clonidine, peripheral adrenergic drugs such as guanethidine, beta-adrenoceptor blockers such as propranolol, and diuretics. Problems with differential diagnosis and with the interpretation of case reports make assessment of psychiatric side effects difficult. Sedation and sleep disturbances are the most common side effects, occurring with methyldopa, clonidine, and propranolol. Only methyldopa is clearly associated with depression. Other reported effects are toxic confusional states and psychotic reactions. These are rare, however, and no clear patterns of development have been recognized.

The use of artemisinin-based combination therapy (ACT) as first-line treatment for uncomplicated malaria was a policy recommended by World Health Organization. In 2004, Ghana changed her first-line anti-malarial drug policy to use ACT. This study examined factors affecting adverse events reporting in northern Ghana after the introduction of ACT. This was a qualitative study based on sixty in-depth interviews with health workers, chemical shop owners and patients with malaria who were given ACT at the health facilities. Purposive sampling method was used to select study participants. The interviews were transcribed, coded into themes using Nvivo 9 software. The thematic analysis framework was used to analyse the data. Study respondents reported body weakness and dizziness as the most frequent side effects they had experienced from the used of ACT. Other side effects they reported were swollen testes, abdominal pain and shivering. These side effects were mostly associated with the use of artesunate-amodiaquine compared to other artemisinin-based combinations. Patients were not provided information about the side effects of the drugs and so did not report when they experienced them. Also long queues at health facilities and unfriendly health worker attitude were the main factors affecting adverse events reporting. Other factors such as wrong use of ACT at home, farming and commercial activities also affected effective adverse events reporting in the study area. Patients' lack of knowledge and health sector drawbacks affected side effect reporting on ACT. Intensive health education on likely side effects of ACT should be provided to patients by health workers. Also, improving health worker attitude toward clients will encourage patients to visit the health facilities when they react negatively to ACT and, subsequently, will improve on adverse events reporting.

To identify the period prevalence of hormonal contraceptive (HC) use and characterise the perceived side effects associated with the menstrual cycle and HC use. 430 elite female athletes completed a questionnaire to assess; the period prevalence of HC use, the reasons for initiation and discontinuation of HCs and the side effects experienced by HC and non-HC users. Descriptive statistics, between-group comparisons and associations between categorical variables were calculated. 49.5% of athletes were currently using HCs and 69.8% had used HCs at some point. Combined oral contraceptives were most commonly used (68.1%), with 30.0% using progestin-only contraceptives (implant = 13.1%; injection = 3.7%; intrauterine system = 2.8%). Perceived negative side effects were more common with progestin-only HC use (39.1%) compared to combined HC use (17.8%; P = 0.001) and were most prevalent in implant users (53.6%; P = 0.004). HC users reported perceived positive side effects relating to the ability to predict and/or manipulate the timing, frequency and amount of menstrual bleeding. Non-HC users had a menstrual cycle length of 29 ± 5 d and 77.4% reported negative side effects during their menstrual cycle, primarily during days 1-2 of menstruation (81.6%). Approximately half of elite athletes used HCs and progestin-only contraceptive users reported greater incidences of negative side effects, especially with the implant. Due to the high inter-individual variability in reported side effects, athletes and practitioners should maintain an open dialogue to pursue the best interests of the athlete.

The aim of this study was to examine how patients recall symptoms at a delayed self-report. Accurate insight into toxicity symptoms during chemotherapy is essential so that nurses and doctors can assess therapeutic tolerance and adjust supportive care accordingly. A non-experimental, longitudinal design was employed. Using the Therapy-Related Symptoms Checklist (TRSC), respondents (n = 142) reported their initial symptoms during the first 7 days of the chemotherapy cycle at two different times: (1) each day of the first seven days after the chemotherapy administration (immediate self-report), and (2) at their next hospital visit for chemotherapy (delayed self-report). We compared the number and severity of symptoms and side effects reported in the immediate and delayed self-reports. Respondents reported significantly fewer symptoms and fewer severe symptoms in the delayed self-report. For 22 out of 25 symptoms the delayed-reported grade was significantly lower than the immediate-reported maximum grade. Compared to the immediate-reported median grade, significant differences occurred in only 10 out of the 25 symptoms. In all cases, except fatigue, the delayed-reported grade was significantly higher than the immediate-reported median grade. This study indicates that delayed self-report of chemotherapy side effects is not an appropriate measure of actual symptoms and side effects experienced by patients. Delayed self-report gives a weaker insight into actual symptom burden. Fatigue is at particular risk to be minimized at the delayed self-report. Therefore it is recommended to assess chemotherapy-related symptoms and side effects by means of immediate self-report. Copyright © 2010 Elsevier Ltd. All rights reserved.

Breast cancer patients younger than 55 completed a questionnaire on psychosocial factors and physical side effects shortly after diagnosis and 9 to 15 months after diagnosis. Those who had used adjuvant chemotherapy were more likely than those who had not to report physical side effects; there was little difference in psychosocial factors. Recent users were more likely than ex-users to report physical side effects, difficulties with domestic chores, and improvement in psychosocial factors. PMID:21229020

Background and aim Adherence to treatment is a critical component of epilepsy management. This study examines whether addressing antiepileptic drug (AED) side effects at every visit is associated with increased patient-reported medication adherence. Patients and methods This study identified 243 adults with epilepsy who were seen at two academic outpatient neurology settings and had at least two visits over a 3-year period. Demographic and clinical characteristics were abstracted. Evidence that AED side effects were addressed was measured through 1) phone interview (patient-reported) and 2) medical records abstraction (physician-documented). Medication adherence was assessed using the validated Morisky Medication Adherence Scale-4. Complete adherence was determined as answering “no” to all questions. Results Sixty-two (25%) patients completed the interviews. Participants and nonparticipants were comparable with respect to demographic and clinical characteristics; however, a smaller proportion of participants had a history of drug-resistant epilepsy than nonparticipants (17.7% vs 30.9%, P=0.04). Among the participants, evidence that AED side effects were addressed was present in 48 (77%) medical records and reported by 51 (82%) patients. Twenty-eight (45%) patients reported complete medication adherence. The most common reason for incomplete adherence was missed medication due to forgetfulness (n=31, 91%). There was no association between addressing AED side effects (neither physician-documented nor patient-reported) and complete medication adherence (P=0.22 and 0.20). Discussion and conclusion Among patients with epilepsy, addressing medication side effects at every visit does not appear to increase patient-reported medication adherence. PMID:27826186

To identify predictors of: uptake of the childhood influenza vaccine in the 2015-2016 influenza season, parental perceptions of side-effects from the influenza vaccine and intention to vaccinate one's child for influenza in the 2016-2017 influenza season. Cross-sectional online survey. Data were collected in England shortly after the end of the 2015-2016 immunization campaign. 1001 parents or guardians of children aged between two and seven. Self-reported uptake of the childhood influenza vaccine in the 2015-2016 influenza season, perception of side-effects from the influenza vaccine and intention to vaccinate one's child in the 2016-2017 influenza season. Self-reported uptake of the childhood influenza vaccine was 52.8%. Factors strongly positively associated with uptake included the child having previously been vaccinated against influenza, perceiving the vaccine to be effective and perceiving the child to be susceptible to flu. Factors strongly negatively associated with uptake included perceiving the vaccine to be unsafe, to cause short-term side-effects or long-term health problems and believing that yearly vaccination may overload the immune system. Predictors of intended vaccine uptake in 2016-2017 were similar. Participants who perceived side-effects after the 2015-2016 vaccination reported being less likely to vaccinate their child next year. Side-effects were more likely to be reported in first-born children, by participants who knew another child who had side-effects, those who thought that the vaccine would interact with medication that the child was currently taking, and those who believed the vaccine causes short-term side-effects. Perceptions about the childhood influenza vaccine show strong associations with uptake, intended uptake and perception of side-effects. Attempts to improve uptake rates from their current low levels must address these perceptions. Copyright © 2017 The Author(s). Published by Elsevier Ltd.. All rights reserved.

Antipsychotic-associated side effects are well known and represent a significant treatment challenge. Still, few large studies have investigated the overall side effect burden of antipsychotics in real-life settings. To describe the occurrence of side effects and perceived burden of antipsychotics in a large naturalistic sample, taking polypharmacy and patient characteristics into account. Patients (n=1087) with psychotic disorders were assessed for side effects using the Udvalg for Kliniske Undersøgelser (UKU) side effect rating scale in addition to assessment of clinical and pharmacological data. Statistical analyses were performed controlling for possible confounding factors. Use of antipsychotics showed significant associations to neurologic and sexual symptoms, sedation and weight gain, and >75% of antipsychotics-users reported side effects. More side effects were observed in patients using several antipsychotics (p=0.002), with increasing total dose (p=0.021) and with antipsychotics in combinations with other psychotropic drugs. Patients and investigators evaluated the side effect burden differently, particularly related to severity, gender and antipsychotics dose. Twice as many females described side effect burden as severe (p=0.004). Patients with psychotic disorders have a high occurrence of symptoms associated with use of antipsychotics, and polypharmacy and female gender are seemingly risk factors for reporting a severe side effect burden. Due to the cross-sectional design evaluation of causality is tentative, and these findings should be further investigated in prospective studies. Copyright © 2017 Elsevier Inc. All rights reserved.

Learning to experience side effects after antidepressant intake - Results from a randomized, controlled, double-blind study.

Side effects play a key role in patients' failure to take antidepressants. There is evidence that verbal suggestions and informed consent elicit expectations that can in turn trigger the occurrence of side effects. Prior experience or learning mechanisms are also assumed to contribute to the development of side effects, although their role has not been thoroughly investigated. In this study, we examined whether an antidepressant's side effects can be learned via Pavlovian conditioning. Participants (n = 39) were randomly allocated to one of two groups and were exposed to a classical conditioning procedure. During acquisition, 19 participants received amitriptyline and 20 participants received a placebo pill. Pills were taken for four nights together with a novel-tasting drink. After a washout phase, both groups received a placebo pill together with the novel-tasting drink (evocation). Side effects were assessed via the Generic Assessment of Side Effects Scale prior to acquisition (baseline), after acquisition, and after evocation. A score of antidepressant-specific side effects was calculated. Participants taking amitriptyline reported significantly more antidepressant-specific side effects after acquisition compared to both baseline and the placebo group. After evocation, participants who underwent the conditioning procedure with amitriptyline reported significantly more antidepressant-specific side effects than those who never received amitriptyline, even though both groups received a placebo. Our results indicate that antidepressant side effects can be learned using a conditioning paradigm and evoked via a placebo pill when applied with the same contextual factors as the verum.

Capturing the patient experience during treatment is important to both regulatory authorities and to patients starting treatment. We identified the symptoms and side effects experienced by patients with advanced non-small-cell lung cancer during osimertinib treatment, to understand treatment expectations, satisfaction, and the level of difficulty coping with the side effects experienced during treatment. Qualitative interviews (approximately 4-6 weeks after treatment initiation and again after approximately 4 months of treatment) were conducted during the phase I/II AURA clinical trial of osimertinib, a tyrosine kinase inhibitor of epidermal growth factor receptor-sensitizing and T790M resistance mutations. During the first interview (23 patients), the most commonly reported symptoms/side effects were coughing, itching, tiredness (each reported by 56.5% of patients), and rash (43.5%). During the second interview (21 patients), compared with the first interview, shortness of breath and diarrhea were reported by more patients (57.1 and 38.1%, respectively; both increased from 34.8%); tiredness remained predominant (42.9%); and itching (38.1%), coughing (38.1%), and rash (14.3%) were reported by fewer patients. At both interviews, the most frequently reported symptoms/side effects were also those most often rated by patients for bothersomeness and severity, and generally received mean scores in the low-to-moderate range. However, several rarely expressed symptoms/side effects (e.g., abdominal pain, frequent day time urination) received high bothersomeness ratings. At the second interview, patients were highly satisfied with osimertinib and had a low level of difficulty in coping with side effects during treatment. These data enhance our understanding of patients' experiences of symptoms/side effects, which could increase the accuracy of the osimertinib benefit-risk assessment, guide management of adverse events, and improve the information given to patients receiving the drug.

Objective Patient expectancies are hypothesized to contribute to the efficacy and side effects of psychiatric treatments, but little research has investigated this hypothesis in the context of psychopharmacological therapies for anxiety. We prospectively investigated whether expectancies predicted efficacy and adverse events in oral therapy for Generalized Anxiety Disorder (GAD), controlling for confounding patient characteristics correlating with outcomes. Methods Expectancies regarding treatment efficacy and side effects were assessed at baseline of an eight week open-label phase of a trial of chamomile for Generalized Anxiety Disorder (GAD). The primary outcome was patient-reported GAD-7 scores, with clinical response and treatment-emergent side-effects as secondary outcomes. Expectancies were used to predict symptomatic and side-effect outcomes. Results Very few baseline patient characteristics predicted either type of expectancy. Controlling for a patient’s predicted recovery based on their baseline characteristics, higher efficacy expectancies at baseline predicted greater change on the GAD-7 (adjusted β = −0.19, p = 0.011). Efficacy expectancies also predicted a higher likelihood of attaining clinical response (adjusted odds ratio = 1.69, p = 0.002). Patients with higher side effect expectancies reported more side effects (adjusted log expected count = 0.26, p = 0.038). Efficacy expectancies were unrelated to side effect reports (log expected count = −0.05, p = 0.680), and side effect expectancies were unrelated to treatment efficacy (β = 0.08, p = 0.306). Conclusions Patients entering chamomile treatment for GAD with more favorable self-generated expectancies for the treatment experience greater improvement and fewer adverse events. Aligning patient expectancies with treatment selections may optimize outcomes. PMID:27716513

Multiple sclerosis (MS) is an immune-mediated and neurodegenerative disease with an unpredictable outcome. Immune-modulatory treatment aims at decreasing long-term disability. With the increasing number of treatment options, it is essential to fully digest the possible side effects of the available therapeutics and to monitor patients is essential. Areas covered: All approved disease-modifying drugs (DMD) for MS are discussed in this review. Mode of action, adverse effects, reported risks for infections and malignancies, and pregnancy related issues are discussed in the review. The authors also provide suggestions for monitoring therapy. For all approved DMDs the pivotal studies have been included for possible side effects, as well as reports by health authorities. For this manuscript, PubMed was checked for reports on side effects for various drugs. Expert opinion: Treatment options in MS are manifold, each carrying different risks. The safety-risk profile for approved agents is favorable. Knowing and monitoring these possible side effects is essential to minimize risks associated with treatment. Presently, the long-term experience for some of these therapies is missing and this must be addressed.

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.

Due to stable incidence and improved survival rates, there are an increasing number of patients living with HIV/AIDS in the USA. Although highly effective, current antiretroviral therapies are associated with a variety of side effects. The role side effects play on health outcomes has not been fully examined. The current study assessed the association of medication side effects with (1) self-assessed health status; (2) work productivity and activity impairment; and (3) healthcare resource utilization. Data were from a cross-sectional patient-reported survey fielded in the USA using a dual methodology of Internet and paper questionnaires. A total of 953 patients living with HIV/AIDS who were currently taking a medication for their condition were included in the analyses. The most frequent side effects reported by patients were fatigue (70.72%), diarrhea (62.96%), insomnia (58.97%), dizziness (52.78%), neuropathy (52.68%), joint pain (52.36%), nausea (51.63%), and abdominal pain (50.37%). The presence of each side effect was associated with reduced self-assessed health status, increased productivity loss, increased activity impairment, and increased healthcare resource use. Controlling for CD4 cell counts in regression modeling did little to diminish the impact of side effects. Although not all side effects were associated with all outcomes, every side effect was associated with worse health status, some measure of increased work productivity loss, and/or some measure of increased healthcare resource use. Patients are living longer with HIV and, therefore, spending a greater length of time on treatment. The results of the current study suggest that many of these patients are experiencing a wide array of side effects from these therapies. These side effects have demonstrated a profound association with self-assessed health, work productivity, and healthcare resource use. Improved management of these side effects or development of treatments with a better side effect profile may have a substantial humanistic and economic benefit.

Antipsychotic drugs are the most frequently prescribed of the psychotropic drugs among the intellectually disabled (ID) population. Given their widespread use, efforts to systematically assess and report side effects are warranted.

Capturing service users' perspectives can highlight additional and different concerns to those of clinicians, but there are no up to date, self-report psychometrically sound measures of side effects of antipsychotic medications. Aim To develop a psychometrically sound measure to identify antipsychotic side effects important to service users, the Maudsley Side Effects (MSE) measure. An initial item bank was subjected to a Delphi exercise (n = 9) with psychiatrists and pharmacists, followed by service user focus groups and expert panels (n = 15) to determine item relevance and language. Feasibility and comprehensive psychometric properties were established in two samples (N43 and N50). We investigated whether we could predict the three most important side effects for individuals from their frequency, severity and life impact. MSE is a 53-item measure with good reliability and validity. Poorer mental and physical health, but not psychotic symptoms, was related to side-effect burden. Seventy-nine percent of items were chosen as one of the three most important effects. Severity, impact and distress only predicted 'putting on weight' which was more distressing, more severe and had more life impact in those for whom it was most important. MSE is a self-report questionnaire that identifies reliably the side-effect burden as experienced by patients. Identifying key side effects important to patients can act as a starting point for joint decision making on the type and the dose of medication.

Beta blockers are one of the oral agents shown to decrease cardiovascular morbidity and mortality rates in randomized, controlled trials, and hence, they are widely used for the management of many cardiovascular situations. In terms of side effects there are 3 major modes of action: (1) contraction of smooth muscles, particularly of bronchi with nonselective agents; (2) exaggerated cardiac effects; and (3) central nervous system effects. There are also some rare side effects of beta blockers, some of which are unpredictable, but the others are related to mode of action at the cellular level. Beta-blocking agents may cause psoriaform eruptions and worsen existing psoriasis. Psoriasis may be an inconvenient side effect of beta blockade. Herein, we report a case of beta-blocker-induced psoriasis.

Calcium channel blockers: spectrum of side effects and drug interactions.

Calcium antagonists are a chemically heterogenous group of agents with potent cardiovascular effects which are beneficial in the treatment of angina pectoris, arterial hypertension and cardiac arrhythmias. The main side effects for the group are dose-dependent and the result of the main action or actions of the calcium antagonists, i.e. vasodilatation, negative inotropic effects and antiarrhythmic effects. Pronounced hypotension is reported for the main calcium antagonist drugs; verapamil, diltiazem and nifedipine. While conduction disturbances and bradycardia are seen more often after verapamil and diltiazem, tachycardia, headache and flush are more frequent after nifedipine. Constipation is relatively frequent after verapamil while nifedipine is reported to induce diarrhea in som patients. Idiosyncratic side effects are rare but have been reported from the skin, mouth, musculoskeletal system, the liver and the central nervous system. These side effects include urticarial rashes, gingival hyperplasia, arthralgia, hepathotoxicity and transistory mental confusion or akathisia. Verapamil, diltiazem and possibly also nifedipine have been reported to increase serum digoxin concentrations but the clinical relevance of these drug interactions are not clear. Furthermore, verapamil and diltiazem may potentiate the effects of beta-adrenergic blocking drugs and verapamil may also potentiate the effects of neuromuscular blocking drugs. It is concluded that side effects after calcium antagonist drugs are mostly trivial and transient although they may sometimes be relatively common. Clinically relevant drug interactions are few. Judged from the point of efficacy and safety, calcium antagonists will have a major place in the future pharmacotherapy of several cardiovascular disorders.

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.

Side effects of antimalarial drug can overlap with malaria symptoms. We evaluated 50 patients with vivax malaria in Mâncio Lima, Acre, treated with chloroquine and primaquine. Patients were evaluated for the presence of 21 symptoms before and after treatment and for reported side effects of these drugs after treatment was started. The most frequent symptoms before medication were headache, fever, chills, sweating, arthralgia, back pain, and weakness, which were present in between 40% and 76% of respondents. The treatment reduced the occurrence of these symptoms and reduced the lack of appetite, but gastrointestinal symptoms and choluria increased in frequency. There were no reports of pale stools before medication, but 12% reported the occurrence of this symptom after treatment started. Other symptoms such as blurred vision (54%), pruritus (22%), paresthesia (6%), insomnia (46%), and “stings” into the skin (22%) were reported after chloroquine was taken. The antimalarial drugs used to treat P. vivax malaria reduce much of the systemic and algic symptoms but cause mainly gastrointestinal side effects that may lead to lack of adherence to drug treatment. It is important to guide the patient for the appearance and the transience of such side effects in order to avoid abandoning treatment. PMID:26357512

Social modeling has the capacity to shape treatment outcomes, including side effects. This study investigated the influence of social modeling of treatment side effects, gender, and participant empathy, on side effects of a placebo treatment. Ninety-six participants (48 females) completed a study purportedly investigating the influence of modafinil (actually placebo) on alertness and fatigue. The participants were randomly seated with a male or female confederate and saw this confederate report experiencing side effects or no side effects. Participant empathy was assessed at baseline. Changes in modeled and general symptoms, and misattribution of symptoms, were assessed during the session and at 24-hr follow-up. During the experimental session, seeing side effect modeling significantly increased modeled symptoms (p = .023, d = 0.56) but not general or misattributed symptoms. Regardless of modeling condition, female participants seated with a female model reported significantly more general symptoms during the session. However, response to social modeling did not differ significantly by model or participant gender. At follow-up, the effect of social modeling of side effects had generalized to other symptoms, resulting in significantly higher rates of modeled symptoms (p = .023, d = 0.48), general symptoms (p = .013, d = 0.49), and misattributed symptoms (p = .022, d = 0.50). The experience of modeled symptoms in response to social modeling was predicted by participants' levels of baseline empathy. Social modeling of symptoms can increase the side effects following treatment, and this effect appears to generalize to a broader range of symptoms and symptom misattribution over time. Higher baseline empathy seems to increase response to social modeling.

Patient expectancies are hypothesized to contribute to the efficacy and side effects of psychiatric treatments, but little research has investigated this hypothesis in the context of psychopharmacological therapies for anxiety. We prospectively investigated whether expectancies predicted efficacy and adverse events in oral therapy for Generalized Anxiety Disorder (GAD), controlling for confounding patient characteristics correlating with outcomes. Expectancies regarding treatment efficacy and side effects were assessed at baseline of an eight week open-label phase of a trial of chamomile for Generalized Anxiety Disorder (GAD). The primary outcome was patient-reported GAD-7 scores, with clinical response and treatment-emergent side-effects as secondary outcomes. Expectancies were used to predict symptomatic and side-effect outcomes. Very few baseline patient characteristics predicted either type of expectancy. Controlling for a patient's predicted recovery based on their baseline characteristics, higher efficacy expectancies at baseline predicted greater change on the GAD-7 (adjusted β = -0.19, p = 0.011). Efficacy expectancies also predicted a higher likelihood of attaining clinical response (adjusted odds ratio = 1.69, p = 0.002). Patients with higher side effect expectancies reported more side effects (adjusted log expected count = 0.26, p = 0.038). Efficacy expectancies were unrelated to side effect reports (log expected count = -0.05, p = 0.680), and side effect expectancies were unrelated to treatment efficacy (β = 0.08, p = 0.306). Patients entering chamomile treatment for GAD with more favorable self-generated expectancies for the treatment experience greater improvement and fewer adverse events. Aligning patient expectancies with treatment selections may optimize outcomes. Trial Number NCT01072344 at ClinicalTrials.gov. Copyright © 2016 Elsevier Ltd. All rights reserved.

In a clinical trial of two antirheumatic agents two methods of collection of side effects were used, one with and the other without a check list of possible symptoms. Findings suggested that the use of a check list interfered with the collection of side effects. Known side effects of aspirin—tinnitus, deafness, and gastrointestinal disturbance—were more efficiently shown and symptoms not included in the check list were more likely to be reported when a check list was not used.

Muscle-related side-effects of statins: from mechanisms to evidence-based solutions.

PubMed

Taylor, Beth A; Thompson, Paul D

2015-06-01

This article highlights the recent findings regarding statin-associated muscle side effects, including mechanisms and treatment as well as the need for more comprehensive clinical trials in statin myalgia. Statin myalgia is difficult to diagnose and treat, as major clinical trials have not routinely assessed muscle side-effects, there are few clinically relevant biomarkers and assessment tools for the symptoms, many apparent statin-related muscle symptoms may be nonspecific and related to other drugs or health conditions, and prevalence estimates vary widely. Data thus suggest that only 30-50% of patients with self-reported statin myalgia actually experience muscle pain on statins during blinded, placebo-controlled trials. In addition, evidence to date involving mechanisms underlying statin myalgia and its range of symptoms and presentations supports the hypothesis that there are multiple, interactive and potentially additive mechanisms underlying statin-associated muscle side-effects. There are likely multiple and interactive mechanisms underlying statin myalgia, and recent studies have produced equivocal data regarding prevalence of statin-associated muscle side-effects, contributing factors and effectiveness of common interventions. Therefore, more clinical trials on statin myalgia are critical to the field, as are systematic resources for quantifying, predicting and reporting statin-associated muscle side-effects.

A point-of-dispensing clinic was held to distribute ciprofloxacin prophylaxis when 2 high school students were reported to the health department with invasive meningococcal disease. Of more than 3,100 school staff and students in attendance, 2,861 received prophylaxis. A survey was administered to students 2 weeks postclinic to better understand the motivations for clinic attendance and to quantify side effects of oral 500-mg ciprofloxacin prophylaxis. Data collected included reasons for attendance and perception of risk for acquiring meningococcal disease, rated on a 1-to-5 scale; type of contact with cases; and side effects. Of 2,888 students, 1,624 completed surveys; 1,390 took ciprofloxacin. The students rated parental influence and directives from the high school as reasons for attendance a mean of 3.97 and 3.34, respectively. The mean rating for risk of acquiring meningococcal disease was 1.49. Only 3% reported direct contact with case(s). Side effects, most commonly headache (17%) and stomachache (10%), were reported in 40% of students. Serious side effects such as rash and facial swelling were reported in <1%. In this adolescent population, few serious side effects and no joint disorders were reported after they ingested single-dose ciprofloxacin; however, many received the prophylaxis unnecessarily. Students were motivated by parents and school officials. Health departments should collaborate with schools to prepare and disseminate messages that balance the risks of unnecessary antibiotic use with those of exposure to disease.

Little is known about the effect of maternal handedness and preferential side of breastfeeding upon macronutrients concentration in human milk (HM). We aimed to compare macronutrients content of HM from both breasts, taking into account the self-reported preferential feeding ('dominant') breast, breast size and handedness (right versus left). We tested the null hypothesis that macronutrients content of HM is not affected by breast dominancy, breast size or maternal handedness. Fifty-seven lactating mothers were recruited. HM macronutrients were measured after mid manual expression using infrared transmission spectroscopy. Out of the 57 mothers recruited, 12 were excluded from the analyses because they brought in insufficient samples. Among the 22 who reported a size difference, 16 (73%) had a larger left breast (P<0.001). Approximately a third of women reported no breastfeeding side dominance, a third reported a right dominance and another third reported a left dominance. Breastfeeding side dominance was unaffected by either handedness or breasts size. When size asymmetry was reported (n=22) the dominant side was also the larger breast in 16 (73%) women, the smaller breast in 2 (9%) women, whereas 4 (18%) additional women with asymmetry had no preferential breastfeeding side. There were no statistically significant differences in macronutrients between the right and the left breasts. In multiple stepwise backward regression analysis, fat, carbohydrate, protein and energy contents were unaffected by maternal handedness, breast side dominance or breast size asymmetry. Macronutrients content of mid expression HM is unaffected by maternal handedness, breast size or breast side dominance.

Recognizing the importance of patient-reported outcomes, this longitudinal, prospective study examined: Changes in health-related quality of life (HRQOL) over seven months following antiepileptic drug (AED) initiation and the relationship of seizures, AED side-effects, and AED type to HRQOL. Parents of 124 children with newly diagnosed epilepsy completed measures of HRQOL and side-effects at each clinic visit. Treatment information was also collected. HRQOL remained stable over time; however, seizures and AED side-effects significantly affected multiple HRQOL domains. Higher seizure activity was associated with decreased Physical HRQOL. Side-effects were negatively associated with all HRQOL domains. Children taking carbamazepine who experienced higher side-effects early in therapy demonstrated declining emotional functioning compared to children experiencing no/some side-effects. AED side-effects, AED type, and seizure frequency were associated with longitudinal HRQOL in children with newly-diagnosed epilepsy. Routine assessment of AED side-effects and HRQOL may be useful for clinical decision making.

Many medications used to manage multiple sclerosis (MS) affect oral health. This review aimed to identify the oral side-effects of the current drugs recommended in Australia to treat MS and make dental practitioners aware of the range of symptoms. The Australian Therapeutic Guidelines and the Australian Medicines Handbook were searched for medications used to treat MS. For each medication, the generic name, class, route of administration, dosage and drug company reported side-effects were extracted from the online Monthly Index of Medical Specialties (MIMs) database. Meyler's Side-effect of Drugs Encyclopaedia was used to identify any additional oral adverse reactions to medications used to treat MS. Fourteen drugs were identified for the treatment of MS progression and 13 drugs for the treatment of MS symptoms. For these medications, 18 oral side-effects were documented: xerostomia was the most common, followed by dysgeusia, dysphagia, mouth ulceration and sinusitis. Anticholinergic drugs caused xerostomia while immunosuppressants resulted in more infection-related side-effects. Dental practitioners should be aware of the range of symptoms likely to be reported by this population. Clinicians are encouraged to continue providing dental care for their patients who develop MS and refer complex cases to specialists. © 2017 Australian Dental Association.

The frigate His Norwegian Majesty's ship (HNoMS) Fridtjof Nansen was participating in operations in the Gulf of Aden in support of the EU mission tasked with protecting vessels from the threat of piracy. The crew was therefore prioritized and given the first batch of Influenza A (H1N1) vaccine (Pandemrix(®)). To investigate the type, frequency, and intensity of side effects after whole-crew vaccination with Pandemrix vaccine in healthy subjects in a controlled environment. A hundred and thirty-three members of the crew were vaccinated, and then they participated in the study. The side effects of the vaccination were evaluated through a survey. Seventy-five per cent of the vaccinated sailors reported adverse reactions to the vaccine, with 9% not being able to perform their daily duties for one day. Muscle pain, headaches, malaise, and fatigue were the most frequent symptoms reported. The vaccination program using Pandemrix H1N1 vaccine resulted in a high rate of side effects, which were generally mild and resolved within a few days. No serious lasting side effects of the vaccination were reported or registered. The adverse effects of the vaccination did not affect the operational capacity of the vessel.

The impact of tamoxifen brand switch on side effects and patient compliance in hormone receptor positive breast cancer patients.

In 2006 Nolvadex was discontinued and replaced by a variety of alternative generic tamoxifen brands for the adjuvant treatment of breast cancer. Anecdotally, patients are switching brands and taking alternative medications to reduce treatment related symptoms. Nevertheless, more severe side effects may equate to better relapse prevention. This study evaluates generic tamoxifen adherence and its correlation with side effects and brand switch. Consecutive disease free ER positive patients (stage I-III) were invited to respond to a questionnaire. 165 of 327 questionnaires were returned (50% response). Pearson's Chi Square test was used for data analysis. 63 patients (38%) reported a switch between generic tamoxifen. 59% of all patients experienced side effects associated with tamoxifen treatment of which 53% were severe. Patients experiencing differential symptoms dependent on tamoxifen brand reported more severe side effects (p = 0.02). Non-prescribed supplements were taken by 42% of all patients with no significant improvement in climacteric symptoms (p = 0.05). The concomitant use of SSRIs appeared to have no effect on symptoms. A significant number of patients considered discontinuing tamoxifen because of the side effects (p = 0.001), yet this did not translate into discontinuation or non-adherence (p = 0.8 and 0.08 respectively). Severe tamoxifen side effects are commonly experienced by breast cancer patients and can be significantly altered by change in tamoxifen brand. Most patients will continue to take tamoxifen, despite side effects to avoid cancer relapse. Supplementation and antidepressants did not improve tamoxifen related side effects in our cohort.

Does contraceptive treatment in wildlife result in side effects? A review of quantitative and anecdotal evidence.

PubMed

Gray, Meeghan E; Cameron, Elissa Z

2010-01-01

The efficacy of contraceptive treatments has been extensively tested, and several formulations are effective at reducing fertility in a range of species. However, these formulations should minimally impact the behavior of individuals and populations before a contraceptive is used for population manipulation, but these effects have received less attention. Potential side effects have been identified theoretically and we reviewed published studies that have investigated side effects on behavior and physiology of individuals or population-level effects, which provided mixed results. Physiological side effects were most prevalent. Most studies reported a lack of secondary effects, but were usually based on qualitative data or anecdotes. A meta-analysis on quantitative studies of side effects showed that secondary effects consistently occur across all categories and all contraceptive types. This contrasts with the qualitative studies, suggesting that anecdotal reports are insufficient to investigate secondary impacts of contraceptive treatment. We conclude that more research is needed to address fundamental questions about secondary effects of contraceptive treatment and experiments are fundamental to conclusions. In addition, researchers are missing a vital opportunity to use contraceptives as an experimental tool to test the influence of reproduction, sex and fertility on the behavior of wildlife species.

To examine the impact of risk-reducing bilateral salpingo-oophorectomy (RRBSO) on sexual function in BRCA gene mutation carriers, compared with the effect on women undergoing BSO (bilateral salpingo-oophorectomy) for benign indications from a qualitative perspective. Our study included 25 women who had undergone either a RRBSO because of BRCA carrier status or a BSO for a benign gynaecologic indication. Women were invited to participate if they were at least six months post-BSO. They took part in an individual, private interview during which they were asked open-ended questions about their sexual health in the context of undergoing BSO. They also completed self-report measures of sexual response, sexual distress, sexual self-image, and mood. Using content analysis of interviews, saturation in themes was reached after 15 interviews and four main themes were identified: (1) preoperative knowledge of sexual side effects, (2) preoperative drive to educate oneself on BSO side effects, (3) partner support, and (4) treatment for sexual side effects. Preoperative awareness of post-BSO sexual side effects was highly correlated with patient satisfaction and inversely correlated with postoperative sexual distress. A majority of participants reported that they did not discuss post-BSO sexual functioning with their physicians, and had to seek out information independently. Satisfaction with RRBSO remained high regardless of whether or not participants reported post-BSO sexual distress. Self-report questionnaires did not reveal any differences between the two groups on measures of sexual function. This study provided a nuanced view of sexual health in women following RRBSO that was not captured by self-report questionnaires. Women with preoperative knowledge of post-BSO sexual side effects report being more prepared for surgery, and experience less sexual distress following their BSO.

Combined with all-trans-retinotic acid (ATRA), ATO has become the first-line induction therapy in treating acute promyelocytic leukemia (APL). The most common side effects of ATO include hepatotoxicity, gastrointestinal symptoms, water-sodium retention, and nervous system damage. In this report, we present a rare side effect, rhabdomyolysis, in a 68-year-old female APL patient who was treated with ATO. After taking 10 mg ATO daily for 6 days, she presented shortness of breath, myodynia, elevated creatine kinase, and acute renal insufficiency. This report describes the first case of ATO-induced rhabdomyolysis.

We identified patient and disease characteristics associated with (1) "current" physical side-effects of any severity; and (2) "severe" physical side-effects "ever" experienced by 3,348 (54%) prostate cancer (PCa) survivors in Ireland diagnosed 2-18 years previously. Postal questionnaires collected symptoms at diagnosis, post-biopsy complications, comorbidities, primary treatments and physical side-effects post-treatment (urinary incontinence, erectile dysfunction, libido loss, bowel problems, breast changes, hot flushes, and fatigue, "ever" and "current" at time of questionnaire completion). Men were grouped by "early" (localised) and "late" (locally advanced/advanced) disease at diagnosis. Multivariable logistic regression analysis identified patient and disease-related factors associated with post-treatment side-effects. Complications post-biopsy were associated with higher risk of "current" libido loss and impotence. Radical prostatectomy was associated with higher risk of "current" and "severe" incontinence, libido loss and impotence in both early and late disease. In early disease, brachytherapy was associated with lower risk of "current" fatigue and "severe" impotence. Comorbidities were associated with higher risk of "current" experience of four side-effects (incontinence, libido loss, bowel problems, fatigue). Men on active surveillance/watchful-waiting reported lower risk of sexual dysfunction. These findings could inform development of tailored information on side-effects, which, in turn, could inform treatment decision-making and post-treatment monitoring. © 2016 John Wiley & Sons Ltd.

Hormonal contraceptives may produce side effects that deter women from their use as a method of family planning. In nutritionally vulnerable populations these effects may be more pronounced due to micronutrient deficiencies and health status. Previous studies have been unable to resolve whether micronutrient supplementation may reduce such side effects. In a longitudinal study, 1011 women obtaining oral contraception through the public health system in rural Cambodia were allocated to either intervention or control groups, receiving either daily Vitamin B6 supplement or care as usual (without placebo). The intervention participants (n = 577) reported fewer side effects in three categories: nausea/no appetite, headache, and depression compared with control group participants (n = 434). Women taking Vitamin B6 supplement were less likely to report side effects in a nutritionally vulnerable population. Underlying nutrition status should be considered by clinicians and reproductive health policy makers in the context of providing contraceptive services. Further investigation into micronutrient supplementation, particularly with B6, in reproductive-aged women using hormonal contraception should be conducted in other settings to determine the potential for widespread adoption.

The objective was to assess the prevalence and patterns of modafinil and zolpidem use among emergency medicine (EM) residents and describe side effects resulting from use. A voluntary, anonymous survey was distributed in February 2006 to EM residents nationally in the context of the national American Board of Emergency Medicine in-training examination. Data regarding frequency and timing of modafinil and zolpidem use were collected, as well as demographic information, reasons for use, side effects, and perceived dependence. A total of 133 of 134 residency programs distributed the surveys (99%). The response rate was 56% of the total number of EM residents who took the in-training examination (2,397/4,281). Past modafinil use was reported by 2.4% (57/2,372) of EM residents, with 66.7% (38/57) of those using modafinil having initiated their use during residency. Past zolpidem use was reported by 21.8% (516/2,367) of EM residents, with 15.3% (362/2,367) reporting use in the past year and 9.3% (221/2,367) in the past month. A total of 324 of 516 (62.8%) of zolpidem users initiated use during residency. Side effects were commonly reported by modafinil users (31.0%)-most frequent were palpitations, insomnia, agitation, and restlessness. Zolpidem users reported side effects (22.6%) including drowsiness, dizziness, headache, hallucinations, depression/mood lability, and amnesia. Zolpidem use is common among EM residents, with most users initiating use during residency. Modafinil use is relatively uncommon, although most residents using have also initiated use during residency. Side effects are commonly reported for both of these agents, and long-term safety remains unclear.

Systematic identification of proteins that elicit drug side effects

2013-01-01

Side effect similarities of drugs have recently been employed to predict new drug targets, and networks of side effects and targets have been used to better understand the mechanism of action of drugs. Here, we report a large-scale analysis to systematically predict and characterize proteins that cause drug side effects. We integrated phenotypic data obtained during clinical trials with known drug–target relations to identify overrepresented protein–side effect combinations. Using independent data, we confirm that most of these overrepresentations point to proteins which, when perturbed, cause side effects. Of 1428 side effects studied, 732 were predicted to be predominantly caused by individual proteins, at least 137 of them backed by existing pharmacological or phenotypic data. We prove this concept in vivo by confirming our prediction that activation of the serotonin 7 receptor (HTR7) is responsible for hyperesthesia in mice, which, in turn, can be prevented by a drug that selectively inhibits HTR7. Taken together, we show that a large fraction of complex drug side effects are mediated by individual proteins and create a reference for such relations. PMID:23632385

Pharmacological Issues for Astronauts

2010-01-01

Medication-induced side effects, called untoward effects by pharmacologists, can be a problem with any medication. Few therapies are perfectly specific for the desired physiological activity; rather they act on multiple biological targets and result in multiple physiological effects. There are several strategies that are employed to prevent, alleviate or counteract medication-induced side effects. The administered dose may be optimized to the lowest possible amount that provides the desired therapeutic effect, with the expectation that untoward effects will be minimized by a lower dose. Empirical trials of different therapies for a particular medical problem may be used in the hopes of finding a drug with minimal side effects for a particular patient, or at least of finding a set of side effects that the patient considers tolerable. If these two strategies have been exhausted, it may be possible to administer another medication to block or ameliorate side effects. A recent search of published scientific literature has revealed that there are medications used in spaceflight that seem to be associated with a significant number of reports of untoward effects. To prevent future medical problems and to improve the well-being and productivity of crew members, it would be best to eliminate (or at least reduce) untoward effects. Reports from the literature will be examined, with the aim of identifying a strategy for reducing untoward effects.

We present a 5-year-old boy who had the complaint of swelling and pain on the right vaccine shot and right axillary areas. The right axillary area was diagnosed as reactive lymphadenitis, which we believe is a rare local side effect of the swine flu vaccine. The key message to take away from this case is that the patient had lymphadenitis as a local side effect of the swine flu vaccine. Lymphadenitis should be reported as a possible local side effect of the swine flu vaccine. PMID:21209734

Few data exist with respect to the occurrence of chronic side effects due to antiepileptic drugs (AED) in routine clinical practice. To evaluate the prevalence of subjective complaints which patients with epilepsy regard as side effects of their AED treatment in a community-based population. Cross-sectional study. Subjects were identified through the database of AED-use in the pharmacies in a suburban area in The Netherlands. Respondents completed a brief questionnaire about their epilepsy, including a checklist with 30 complaints, which are common in AED users. We present data of 346 responding adults with treated epilepsy from a population of 107,000 adult inhabitants. Eighty percent was using monotherapy, with few patients taking new AEDs. Almost 60% of the patients reported complaints probably due to side effects in at least three domains. General CNS-related side effects were reported most often; memory problems (21.4% of the patients) and fatigue (20.3%) were dominant. Polytherapy was associated with more side effects than monotherapy. We identified differences in profiles of complaints between valproate, carbamazepine and phenytoin monotherapy. Complaints were not substantially associated with ongoing seizures or other treatment factors. The majority of patients taking AEDs for epilepsy think they have side effects form their drugs, even when seizures were in remission and when monotherapy was used. Our findings suggest a need to improve monitoring of complaints of side effects of AEDs and to explore the feasibility of interventions aimed at reduction of such complaints in everyday clinical practice.

A Cutaneous Lupus Erythematosus-Like Eruption Induced by Hydroxyurea.

Hydroxyurea is a medication with many well-described cutaneous side effects, notably the dermatomyositis-like eruption known as hydroxyurea dermopathy. Although systemic lupus erythematosus has been reported with hydroxyurea use, cutaneous lupus has not. We report a novel case of chronic cutaneous lupus induced by hydroxyurea and propose that this is a side effect that is distinct from hydroxyurea dermopathy. © 2016 Wiley Periodicals, Inc.

Anti-programmed cell death receptor-1 (PD-1) antibodies represent an effective treatment option for metastatic melanoma as well as for other cancer entities. They act via blockade of the PD-1 receptor, an inhibitor of the T-cell effector mechanisms that limit immune responses against tumours. As reported for ipilimumab, the anti-PD-1 antibodies pembrolizumab and nivolumab can induce immune-related adverse events (irAEs). These side-effects affect skin, gastrointestinal tract, liver, endocrine system and other organ systems. Since life-threatening and fatal irAEs have been reported, adequate diagnosis and management are essential. In total, 496 patients with metastatic melanoma from 15 skin cancer centers were treated with pembrolizumab or nivolumab; 242 side-effects were described in 138 patients. In 116 of the 138 patients, side-effects affected the skin, gastrointestinal tract, liver, endocrine, and renal system. Rare side-effects included diabetes mellitus, lichen planus, and pancreas insufficiency due to pancreatitis. Anti-PD1 antibodies can induce a plethora of irAEs. The knowledge of them will allow prompt diagnosis and improve the management resulting in decreased morbidity. Copyright © 2016 Elsevier Ltd. All rights reserved.

The primary aim was to assess usability of the My Medicines and Me Questionnaire (M3Q) as a self-reported questionnaire for mental health patients to subjectively express side effects experienced with their psychotropic medications. The secondary aim was to evaluate patients' attitudes towards treatment and psychotropic medications following dialogue with their clinicians about side effects. Questionnaires were administered at six adult mental health facilities. A total of 205 participants were divided into intervention (facilitated dialogue) and non-intervention groups (no facilitated dialogue). The mean completion time for the M3Q was 15min (SD=6.5) with only 11 (5%) patients requiring assistance. The most commonly reported side effect was sedation (77%) and weight gain was ranked as the most bothersome (23%). The previously validated M3Q provided patients with the opportunity to express the impact these effects had on their lives. Side effects were the most common reason given for non-adherence. There were no significant changes in patient attitudes towards treatment and medications in the intervention group, mainly due to the logistical challenges in the clinicians' ability to view the questionnaire for the subsequent meeting with the patient. The M3Q demonstrated its usability in allowing patients to easily express their subjective experiences with side effects. Copyright © 2015 Elsevier Ireland Ltd. All rights reserved.

To establish how the terms recommended by the European Commission to describe side-effect risk in patient information leaflets (PILs) influences expectations of side-effects and to identify factors associated with these side-effect expectations. A cross-sectional online survey was carried out by a market research company. Data were collected in England between 18th March and 1st April 2016. A total of 1003 adults aged between 18 and 65. Self-reported expectation that the described side-effects would affect participants if they took the medicine, measured on a likelihood scale from 1 (very unlikely) to 5 (very likely). Participants formed high expectations of side-effects for "very common" and "common" side-effects, with 51.9% and 45.0% of participants rating these as "very likely" or "likely" to happen to them, respectively. This fell to 8.1% for "uncommon," 5.8% for "rare" and 4.1% for "very rare." For each descriptor, higher expectations of side-effects were more associated with women or being from an ethnic minority, or having less education, a household illness, high perceived sensitivity to medicines or negative beliefs about medicines. The current use of verbal descriptors to communicate side-effect risk in PILs leads to high side-effect expectations. These expectations could contribute to nocebo-induced medication side-effects experienced by patients. Additional work is required to identify ways to improve the way risk information is conveyed in PILs. © 2017 The Authors Health Expectations Published by John Wiley & Sons Ltd.

Network-based methods are playing an increasingly important role in drug design. Our main question in this paper was whether the efficiency of drug target proteins to spread perturbations in the human interactome is larger if the binding drugs have side effects, as compared to those which have no reported side effects. Our results showed that in general, drug targets were better spreaders of perturbations than non-target proteins, and in particular, targets of drugs with side effects were also better spreaders of perturbations than targets of drugs having no reported side effects in human protein-protein interaction networks. Colorectal cancer-related proteins were good spreaders and had a high centrality, while type 2 diabetes-related proteins showed an average spreading efficiency and had an average centrality in the human interactome. Moreover, the interactome-distance between drug targets and disease-related proteins was higher in diabetes than in colorectal cancer. Our results may help a better understanding of the network position and dynamics of drug targets and disease-related proteins, and may contribute to develop additional, network-based tests to increase the potential safety of drug candidates.

2018-03-01

Despite the medical advancements in HIV treatment, realities of side effects are faced by people living with HIV (PLWH) who receive antiretroviral therapy (ART). Mixed findings have been reported on the association between side effects and ART adherence. However, few studies have explored the combined side effects and behavior-related information on medication adherence. The aim of the current study is to examine moderator role of ART-related knowledge between side effects and ART adherence. A cross-sectional survey was conducted among 2987 PLWH from October 2012 to August 2013 in China. Of the total sample, 2095 patients had received ART and provided ART adherence. Side effects, ART-related knowledge, and ART adherence, as well as potential covariates were assessed. The results revealed that there was a negative relationship of side effects and ART adherence existed among low and medium levels of ART-related knowledge, but not among high level of knowledge. Future interventions to promote HIV medication adherence should focus on providing behavior-related information education among PLWH.

Gastrointestinal side effects are the limiting factor in the prescription of non-steroidal antirheumatic drugs (NSAID). However, there are no recent data from Austria. The aim of this prevalence study was therefore to assess the gastrointestinal risk from NSAID in Austria. A total of 1347 patients were observed in an outpatient setting between March 2000 and February 2001. Side effects from NSAID were documented by questionnaire at two time points with a mean interval of 31 days. Documented data were analysed descriptively using an explorative strategy. The prevalence of side effects was compared to data from literature. Side effects were reported by 18.1% of the patients, severe gastro-intestinal complications (ulcer, bleeding, perforation) were diagnosed in 0.7%. Prescription of effective GI-protection (proton pump inhibitors, misoprostole, famotidin in high dose) was seen in only one third of the patients at risk. The prevalence of severe gastrointestinal side effects by NSAIDs assessed in our study was clearly lower than the prevalence reported in the Anglo-American literature. This may be due to a different prescription behaviour: about 75% of the patients took Diclofenac, lbuprofen or Meloxicam, drugs which have a very low potential of gastrointestinal complications. However, more information for general practitioners is needed yet to sufficiently protect patients at gastrointestinal risk from NSAID.

Always read the leaflet-Getting the best information with every medicine. (Report of the Committee on Safety of Medicines Working Group on Patient Information). London: The Stationery Office, 2005.]. 134 Cancer Research UK (CRUK) website users were recruited via a 'pop-up'. Using a 2x2 factorial design, participants were randomly allocated to one of four conditions and asked to: imagine they had to take tamoxifen, estimate the risks of 4 side effects, and indicate a presentation mode preference. Those presented with absolute frequencies demonstrated greater accuracy in estimating 2 of 4 side effects, and of any side effect occurring, than those presented with frequency bands. Those presented with combined descriptors were more accurate at estimating the risk of pulmonary embolism than those presented with numeric descriptors only. Absolute frequencies outperform frequency bands when presenting side effect risk information. However, presenting such exact frequencies for every side effect may be much less digestible than all side effects listed under 5 frequency bands. Combined numerical and verbal descriptors may be better than numeric only descriptors when describing infrequent side effects. Information about side effects should be presented in ways that patients prefer, and which result in most accurate risk estimates. Copyright (c) 2009 Elsevier Ireland Ltd. All rights reserved.

Ginseng root extract is a widely used herbal product not devoid of side effects. This report describes the development of manic symptoms after ginseng consumption in a patient with affective disorder. Other potentially harmful side effects of ginseng are also reviewed. A single case report. A 56-year-old woman with previous affective disorder presented a manic episode during ginseng intake. Symptoms disappeared rapidly with low doses of neuroleptics and benzodiazepines after ginseng suppression. Ginseng may produce manic symptoms. A special risk situation seems to be affective patients under antidepressant medication. The case emphasizes the lack of harmlessness of herbal products. Patients should be routinely asked about the use of herbal products and diet supplements.

Sexual dysfunction is a bothersome side effect of several medications, though it has not yet been reported with the use of ledipasvir/sofosbuvir for the treatment of hepatitis C. However, sexual dysfunction is a potentially unrecognized side effect of ledipasvir/sofosbuvir that could result in nonadherence and treatment failure. We report a case of a 42-year-old man with a sudden onset of sexual dysfunction with the initiation of ledipasvir/sofosbuvir for the treatment of hepatitis C. The patient had no prior history or risk factors for the development of sexual dysfunction. His symptoms resolved upon discontinuation of ledipasvir/sofosbuvir after a successful 12-week course. Clinicians should be aware that sexual dysfunction is a possible side effect of ledipasvir/sofosbuvir and educate patients appropriately. Adherence should be emphasized as the risks of untreated hepatitis C virus far outweigh transient sexual dysfunction.

Use of energy drinks and energy shots among military personnel is controversial. High amounts of caffeine (the primary active ingredient in these products) may impact performance of military duties. The impact of caffeine overconsumption and potential subsequent side effects that might be experienced by service members with unique roles and responsibilities is a concern. Reported here are the prevalence of use, reasons for use, and side effects associated with consumption of energy drinks and energy shots among several populations of active duty personnel in the US military. A snowball survey was sent to over 10,000 active duty personnel. A total of 586 (∼6% response rate) individuals completed a 30-item electronic survey. Over half of respondents (53%) reported consuming an energy drink at least once in the past 30 days. One in five (19%) reported energy shot consumption in the prior 30 days. One in five (19%) also reported consuming an energy drink in combination with an alcoholic beverage. Age and gender were significantly associated with energy drink consumption. Young male respondents (18-29 years) reported the highest use of both energy drinks and energy shots. Among those reporting energy drink and energy shot use, the most common reasons for consumption were to improve mental alertness (61%) and to improve mental (29%) and physical (20%) endurance. Nearly two-thirds (65%) of users self-reported at least one side effect. The most commonly reported side effects included increased pulse rate/palpitations, restlessness, and difficulty sleeping. Use of energy products among military personnel is common and has the potential to impact warrior health and military readiness. © 2014 International Life Sciences Institute.

HIV or HIV-Therapy? Causal attributions of symptoms and their impact on treatment decisions among women and men with HIV

PubMed Central

2009-01-01

Objectives Among people with HIV, we examined symptom attribution to HIV or HIV-therapy, awareness of potential side effects and discontinuation of treatment, as well as sex/gender differences. Methods HIV-patients (N = 168, 46% female) completed a comprehensive symptom checklist (attributing each endorsed symptom to HIV, HIV-therapy, or other causes), reported reasons for treatment discontinuations and potential ART-related laboratory abnormalities. Results Main symptom areas were fatigue/sleep/energy, depression/mood, lipodystrophy, and gastrointestinal, dermatological, and neurological problems. Top HIV-attributed symptoms were lack of stamina/energy in both genders, night sweats, depression, mood swings in women; and fatigue, lethargy, difficulties concentrating in men. Women attributed symptoms less frequently to HIV than men, particularly fa-tigue(p < .01). Top treatment-attributed symptoms were lipodystrophy and gastrointestinal problems in both genders. Symptom attribution to HIV-therapy did not differ between genders. Over the past six months, 22% switched/interrupted ART due to side effects. In women, side effect-related treatment decisions were more complex, involving more side effects and substances. Remarkably, women took predominantly protease inhibitor-sparing regimens (p = .05). Both genders reported only 15% of potential ART-related laboratory abnormalities but more than 50% had laboratory abnormalities. Notably, women had fewer elevated renal parameters (p < .01). Conclusions Men may attribute symptoms more often to HIV and maintain a treatment-regimen despite side effects, whereas women may be more prudent in avoiding treatment side effects. Lacking awareness of laboratory abnormalities in both genders potentially indicates gaps in physician-patient communication. Gender differences in causal attributions of symptoms/side effects may influence treatment decisions. PMID:19380286

Ten studies with original IViT ocular side effect data were included in this systematic review. In these combined reports, a total of 1287 intravitreal injections were given to 306 eyes of 295 patients, with a mean follow-up of 74.1 months. Two hundred sixty-one (88.5%) patients received comparatively standard melphalan IViT doses (8-30 mcg). Ocular side effects occurred in 38 patients (17 significant, 21 minor). The proportion of patients experiencing potentially significant ocular side effects following standard melphalan IViT regimens was 0.031 (8/261; 95% CI 0.013 to 0.06). The side effects of these eight included iris atrophy in three, two each with chorioretinal atrophy and vitreous haemorrhage and one with retinal detachment. Of the other nine patients with significant complications, five experienced sight-threatening complications following dramatic dose escalations (four with melphalan, one with thiotepa), three experienced complications that are commonly associated with concurrent therapies given to these patients and one had a retinal detachment. Of the 61 patients receiving IViT via safety-enhancing injection techniques, all six significant side effects were either attributed to the therapeutic dose or confounded by concurrent treatments. Significant ocular complications following IViT for retinoblastoma are uncommon, and this risk may be reduced further by the use of careful injection technique and standard dosing regimens. Care must be taken in the dosing of intravitreal treatments to avoid potentially irreversible vision loss.

Side-effects and technical problems in cytapheresis with cell separators. Results of a retrospective multicenter study.

Kretschmer, V

1987-09-01

On the basis of a survey, the acute side-effects and technical problems in a total of 77,525 cytaphereses (IFC 36,530, CFC 40,995) in donors at 39 hemapheresis centers were retrospectively analysed statistically. In general, relevant donor side-effects (0.78%-1.05%) were more rare than the primary donor-independent disturbances (1.65%-2.63%). The donor side-effects predominated merely with the use of the cell separators Haemonetics M30/Belco (1.06% vs. 0.57%). These were mainly circulatory reactions (0.83%), which were generally much more frequent with IFC (0.54%) than with CFC (IBM/Cobe 0.11%, CS-3000 0.19%). Potentially fatal complications were not reported. The frequency of side-effects, disturbances and discontinuations correlated inversely with the separation rate of the individual centers per method. Centers in which two or three methods were applied simultaneously reported a higher frequency of side-effects and disturbances. Hemolysis was only observed with IFC (0.09%), but not with the use of the Haemonetics V50. The greater susceptibility to disturbances of technical/methodological/operational origin essentially results from the more elaborate, but not yet perfected technology, including computer control and monitoring, as well as defects in the production of the much more complicated disposable sets. Thus the highest rate of discontinuations was calculated for the system which is so far the most sophisticated technically (CS-3000, 1.85%). Although the primary donor-independent problems sometimes correlate directly with the manifestation of donor side-effects, the greater technological sophistication of automatically controlled and monitored systems cannot be dispensed with, since only in this way can potentially fatal risks for the donors be largely ruled out.(ABSTRACT TRUNCATED AT 250 WORDS)

In a previously reported randomized controlled trial, formerly opioid-dependent prisoners were more likely to enter community drug abuse treatment when they were inducted in prison onto buprenorphine/naloxone (hereafter called buprenorphine) than when they received counseling without buprenorphine in prison (47.5% vs. 33.7%, p=0.012) (Gordon et al., 2014). In this communication we report on the results of the induction schedule and the adverse event profile seen in pre-release prisoners inducted onto buprenorphine. This paper examines the dose induction procedure, a comparison of the proposed versus actual doses given per week, and side effects reported for 104 adult participants who were randomized to buprenorphine treatment in prison. Self-reported side effects were analyzed using generalized estimated equations to determine changes over time in side effects. Study participants were inducted onto buprenorphine at a rate faster than the induction schedule. Of the 104 (72 males, 32 females) buprenorphine recipients, 64 (37 males, 27 females) remained on medication at release from prison. Nine participants (8.6%) discontinued buprenorphine because of unpleasant opioid side effects. There were no serious adverse events reported during the in-prison phase of the study. Constipation was the most frequent symptom reported (69 percent). Our findings suggest that buprenorphine administered to non-opioid-tolerant adults should be started at a lower, individualized dose than customarily used for adults actively using opioids, and that non-opioid-tolerant pre-release prisoners can be successfully inducted onto therapeutic doses prior to release.

Dermatological side effects of psychopharmacological drugs are fortunately not so often. They are mostly presented in the group of mood stabilizers and antiepileptic drugs, particularly the carbamazepine and lamotrigine, and can be manifested through the Stevens Johnson syndrome, Toxic Epidermal Necrolysis (TEN)/Lyell's syndrome with about 30% lethality. According to the literature the group of phenothiazines is the category of drugs with rare appearances of skin reactions. Promazine, aliphatic phenothiazines antipsychotic, including less frequent side effects in the leaflet states increased skin sensitivity to sun, skin rash-associated with contact dermatitis, allergic reactions, cholestatic icterus. The only reported dermatological side effect of promazine is its metabolites deposition in the cornea. Analyzing the e-data basis we have not found references connecting the Exanthema medicamentosum as a side effect of promazine. A forty-two years old female patient was admitted to the Dermatological Clinic because of suspected exanthema, undoubtedly caused by promazine as a medication for Sy. Borderline.

This retrospective case series describes ocular side-effects associated with imatinib mesylate (Gleevec) and the clinical characteristics of these adverse reactions. A chart review of 104 patients on imatinib mesylate therapy from Oregon Health & Science University's Cancer Center were studied with regard to ocular side-effects. In addition, spontaneous reports from the Food and Drug Administration, the World Health Organization, and the National Registry of Drug-Induced Ocular Side-Effects databases were reviewed, including a Medline literature search. Seventy-three (70%) of the patients at OHSU developed periorbital edema and 19 patients (18%) developed epiphora after receiving imatinib mesylate. Average dose was 407.5+/-60 mg. Periorbital edema occurred an average of 68+/-48 days after initiation of therapy. WHO classification of side-effects is as follows: certain: periorbital edema; probable: epiphora; possible: extraocular muscle palsy, ptosis, blepharoconjunctivitis; unlikely: glaucoma, papilledema, retinal hemorrhage, photosensitivity, abnormal vision, and increased intraocular pressure. Periorbital edema and epiphora are the two most common ocular side-effects related to imatinib mesylate therapy. Clinical characteristics of imatinib mesylate induced periorbital edema are described. Management of ocular side-effects is conservative except in very rare cases of visually significant periorbital edema.

We compared the analgesic efficacy and incidence of side effects when low{\\hyphen}dose (0.3 mg{\\sol}kg) ketamine (LDK) is administered as a slow infusion (SI) over 15 minutes versus an intravenous push (IVP) over one minute. This was a prospective, randomized, double blind, double dummy, placebo{\\hyphen}controlled trial of adult ED patients presenting with moderate to severe pain (numerical rating score ≥ 5). Patients received ketamine 0.3mg{\\sol}kg administered either as a SI or IVP. Our primary outcome was the proportion of patients experiencing any psychoperceptual side effect over 60 minutes. A secondary outcome was incidence of moderate or greater psychoperceptual side effects. Additional outcomes included reduction in pain NRS scores at 60 minutes and percent maximum summed pain intensity difference ({\\percnt}SPID). Fifty{\\hyphen}nine participants completed the study. 86.2{\\percnt} of the IVP arm and 70.0{\\percnt} of the SI arm experienced any side effect (difference 16.2{\\percnt}, 95{\\percnt}CI {\\hyphen}5.4 - 37.8). We found a large reduction in moderate or greater psychoperceptual side effects with SI administration-75.9{\\percnt} reported moderate or greater side effects versus 43.4{\\percnt} in the SI arm (difference 32.5{\\percnt}, 95{\\percnt}CI 7.9 - 57.1). Additionally, the IVP arm experienced more hallucinations (n{\\equal}8, 27.6{\\percnt}) than the SI arm (SI n{\\equal}2, 6.7{\\percnt}; difference 20.9{\\percnt}, 95{\\percnt}CI 1.8 - 43.4). We found no significant differences in analgesic efficacy. At 60 minutes, the mean {\\percnt}SPID in the IVP and SI arms was 39.9{\\percnt} and 33.5{\\percnt}, respectively, with a difference of 6.5{\\percnt} (95{\\percnt}CI {\\hyphen}5.8 - 18.7). Most patients who are administered LDK experience a psychoperceptual side effect regardless of administration via SI or IVP. However, patients receiving LDK as a SI reported significantly fewer moderate or greater psychoperceptual side effects and hallucinations with equivalent analgesia.

Treatment with finasteride 1 mg/day represents the therapy of choice for androgenetic alopecia (AGA). We investigated how Italian dermatologists approach use of finasteride for treatment of AGA and common side effects reported by patients. A tablet-based survey was conducted from February 2017 to January 2018 in Italy to investigating use of 1 mg/day finasteride in the treatment of AGA. Approximately 1153 Italian dermatologists were surveyed about prescription frequency, therapy duration, treatment practices, and side effects eventually reported. Dermatologists considered treatment with 1 mg/day finasteride to be the most efficacious treatment for AGA, as reflecting by its long-term (5 years) prescription. Data on sexual side effects from our survey are in line with previous scientific evidence, especially regarding loss of libido, erectile dysfunction, and problems with ejaculation, but also in the psychological sphere and regarding physical impairments such as myalgia and loss of muscle tone. This is the first preliminary observational study on how Italian dermatologists approach use of finasteride to treat AGA. Although side effects have been reported, especially in the sexual sphere, lack of alternative treatments with the same efficacy leads dermatologists to prescribe 1 mg/day finasteride with a tendency to prolong therapy in the long term.

Yohimbine is an indole alkaloid obtained from the yohimbe tree, a common tree in West Africa. We describe a forty-two-year black man in whom a generalized erythrodermic skin eruption, progressive renal failure, and lupus-like syndrome developed following treatment with the drug, yohimbine. A literature review failed to reveal any reported association of these side effects. We review current information on yohimbine's use in male impotence, reported side effects, and its role as a drug allergen.

Although the demand from patients for integrative medicine is increasing, complementary medicine services are still quite heterogeneous and have not been incorporated into clinical routine. The aim of this study was to systematically evaluate improvements in side effects and quality of life associated with a hospital-based integrative medicine program in the modern breast cancer patient care setting. In a cross-sectional study, integrative health counseling and treatment were evaluated in women with breast cancer. Over a 15-month period, data for 75 patients from an integrative medicine consultancy service with standardized operating procedures were collected at the University Breast Center for Franconia. At baseline, the patients answered a questionnaire on their medical history, symptoms, and the treatment goals they were hoping to achieve with integrative medicine. In the follow-up, patient-reported outcomes related to side effects of conventional cancer treatment and patients' quality of life were analyzed. Among 60 patients with the therapy goal of reducing the side effects of conventional treatment, 46 (76.7%) were successful. Among 57 patients hoping to improve disease-related quality of life, 46 (82%) reported success. Whereas patients with metastatic disease achieved a reduction in the side effects of conventional therapy, quality-of-life improvements were predominantly achieved by patients with a good treatment prognosis. Breast cancer patients benefit from the counseling and treatment provided with integrative medicine in all phases of tumor disease. Integrative treatment services should be included as part of patient care in clinical routine work to offer patients the maximum quality of care and safety with complementary therapies.

This review highlights recent advances in the investigation of genetic factors for antipsychotic response and side effects. Antipsychotics prescribed to treat psychotic symptoms are variable in efficacy and propensity for causing side effects. The major side effects include tardive dyskinesia, antipsychotic-induced weight gain (AIWG), and clozapine-induced agranulocytosis (CIA). Several promising associations of polymorphisms in genes including HSPG2, CNR1, and DPP6 with tardive dyskinesia have been reported. In particular, a functional genetic polymorphism in SLC18A2, which is a target of recently approved tardive dyskinesia medication valbenazine, was associated with tardive dyskinesia. Similarly, several consistent findings primarily from genes modulating energy homeostasis have also been reported (e.g. MC4R, HTR2C). CIA has been consistently associated with polymorphisms in the HLA genes (HLA-DQB1 and HLA-B). The association findings between glutamate system genes and antipsychotic response require additional replications. The findings to date are promising and provide us a better understanding of the development of side effects and response to antipsychotics. However, more comprehensive investigations in large, well characterized samples will bring us closer to clinically actionable findings.

"Side effects" of ECT are mainly depressive phenomena and are independent of age.

The aetiology of reported side effects of electroconvulsive therapy (ECT) is unclear. We examined the interaction of depression and age on adverse neuropsychological and putative side effects of ECT. Inpatients (N=81; median age 70 years) with major depression were assessed prospectively pre-ECT, immediately post-ECT and 1-3 years later. Patients were administered the Hamilton Rating Scale for Depression (HRSD), the Global Assessment of Functioning scale (GAF) and neuropsychological tests from the Wechsler Memory Scale. Side effects and total burden scores were rated pre- and post-treatment. HRSD and GAF scores improved with treatment after ECT, but the prevalence and total burden of side effects were unchanged. Side effect burden was related to depression level before and after ECT. Improvement in depression correlated with reduction in side effect burden. There was a significant decline in side effect burden after controlling for change in depression. Patients' scores on neuropsychological measures did not appear to change after ECT or between pre-ECT and follow-up. Re-analysis, allowing for age, chronicity of depression, medication use and development of dementia, did not alter the findings. lack of a control group, lack of information on ECT technique, incomplete data sets and limited neuropsychological testing. ECT, an effective treatment for depression, does not cause significant side effects or neuropsychological impairment, which are more likely to be depressive phenomena. ECT appears to be safe for old (> or =65 years) and very old (> or =75 years) patients, who do not appear to be more susceptible to adverse effects.

2017-07-14

BACKGROUND Tyrosine kinase inhibitors (TKIs) are currently an important targeted drug class in the treatment of chronic myeloid leukemia (CML). Imatinib was the first approved TKI for CML in 2001. Nilotinib is a second-generation TKI, approved in 2007; it inhibits BCR-ABL, PDGFR, and c-KIT, and is 30 times more potent than imatinib. Tyrosine kinase enzymes are expressed in multiple tissues and are involved in several signaling pathways; they have been shown to have several off-target side effects. CASE REPORT We report a case of an elderly male with CML and no history of gastrointestinal diseases, treated with nilotinib, and developed recurrent gastric polyps after three years of treatment. We excluded common causes of gastric polyps and therefore considered nilotinib as a probable cause of recurrent gastric polyps. CONCLUSIONS Recurrent gastric polyps could be a potential side effect of nilotinib treatment. Careful long-term monitoring of patients on TKI therapy is necessary and further long-term studies of TKI side effects are needed.

First-trimester surgical abortion is a common procedure. Pain control during this procedure is still an unsolved problem. In this randomized, double-blind placebo-controlled study, women presenting for first-trimester surgical abortion received intramuscular phloroglucinol (4 mL) or placebo (normal saline, 4 mL). Visual analog scales (VAS) for pain immediately and 30 min after the procedure and side effects of the drug were recorded. There was no significant difference between groups in the pain level immediately and 30 min after the procedure; 70.7% of the phloroglucinol group (n=58 cases) and 56.9% of the placebo group (n=58 cases ) reported mild pain; 27.6% and 34.5%, respectively, reported moderate pain; and 1.7% and 8.6%, respectively, reported severe pain. Thirty minutes after the procedure, the median pain score was reduced to 1.3 in both groups. Postoperative side effects were reported, but there was no significant difference between groups for nausea or vomiting and blood pressure. The use of this dose of phloroglucinol, during first-trimester abortion by suction evacuation under local anesthesia with lidocaine, did not relieve pain, but caused no side effects.

Background: Occupational therapy is an important co-therapy in psychiatric therapy. It is a common belief that no risks are associated with occupational therapy. Negative effects caused by group therapy, especially occupational therapy, have not been in the focus of research yet. In this study we want to illustrate possible types and intensities of group side effects through occupational therapy. Patients and Methods: Patients of an inpatient rehabilitation facility filled out the Adverse Treatment Reaction Group Checklist. The checklist contains 47 items divided in six dimensions: group size, content, group participants, group outcome and global. The self-rating used a 5-point likert scale (0 = not at all; 4 = very much, extremely stressful) and gives information about types and intensities of the side effects. Results: 88.9 % of 45 patients reported negative effects of occupational group therapy. 28.9 % of the patients rated the side effect as at least severe. Discussion: Occupational therapy is associated with side effects as every other group therapy. Possible side effects caused by group therapy should be considered while planning and implementing occupational therapy. © Georg Thieme Verlag KG Stuttgart · New York.

The effect of qualifying language on perceptions of drug appeal, drug experience, and estimates of side-effect incidence in DTC advertising.

PubMed

Davis, Joel

2007-01-01

This study examined how the use of qualifying language in direct-to-consumer (DTC) pharmaceutical advertising affects consumers' perceptions of drug appeal, anticipated pleasantness of drug usage, and the expected incidence of side-effect occurrence. A sample of 669 individuals participated in a 2 x 8 complete factorial design. The design manipulated the number of side effects associated with drug use and the type of qualifying language used to describe the side effects. The eight experimental qualifying language cells represented one control condition (no qualifying language), three cells where each of three types of qualifying language were presented individually, and four cells where qualifying language was combined. The results indicate that qualifying language has a profound effect on drug perceptions, especially when used in combination. Drug appeal and the anticipated drug-using experience almost always were more positive in the presence of qualifying language. Qualifying language appears to exert its influence by causing individuals to reduce their estimate of the likelihood of experiencing individual side effects. Policy implications of the research, particularly for evaluation of "fair balance" and the reporting of side effects, are presented.

Space motion sickness in astronauts during spaceflight causes significant discomfort, which might impede their functionality. Pharmacological treatment has been mainly restricted to promethazine. Transdermal and oral scopolamine have also been used in space; however, their use was reduced due to unpredictable effectiveness and side effects. Recently, intranasal scopolamine administration has gained much interest, since this route ensures fast and reliable absorption with a decreased incidence of undesirable side effects. The aim of this study was to evaluate the effect of intranasal scopolamine on cognitive performance and to determine its side effects. This double-blind, placebo controlled, repeated measures study evaluated vigilant attention, short-term memory, implicit memory and working memory. Side effects were reported on a 22-item questionnaire and sleepiness was assessed by the Karolinska, Stanford and Epworth Sleepiness Scales. Scopolamine had no effect on cognitive function. Only the Karolinska score was significantly increased for scopolamine compared to placebo. Participants reported a dry mouth and dizziness after receiving scopolamine. Results show that intranasal scopolamine did not impair cognitive performance. Intranasal scopolamine might be a good alternative to promethazine for the alleviation of space motion sickness, since the agent has minimal sedative effects and does not hamper cognitive performance. © The Author(s) 2015.

Women cannot discriminate between different paracervical block techniques applied to opposite sides of the cervix.

PubMed

Grossman, R A

1995-09-01

The purpose of this study was to determine whether women can discriminate better from less effective paracervical block techniques applied to opposite sides of the cervix. If this discrimination could be made, it would be possible to compare different techniques and thus improve the quality of paracervical anesthesia. Two milliliters of local anesthetic was applied to one side and 6 ml to the other side of volunteers' cervices before cervical dilation. Statistical examination was by sequential analysis. The study was stopped after 47 subjects had entered, when sequential analysis found that there was no significant difference in women's perception of pain. Nine women reported more pain on the side with more anesthesia and eight reported more pain on the side with less anesthesia. Because the amount of anesthesia did not make a difference, the null hypothesis (that women cannot discriminate between different anesthetic techniques) was accepted. Women are not able to discriminate different doses of local anesthetic when applied to opposite sides of the cervix.

CHECKPOINT INHIBITOR IMMUNE THERAPY: Systemic Indications and Ophthalmic Side Effects.

2018-06-01

To review immune checkpoint inhibitor indications and ophthalmic side effects. A literature review was performed using a PubMed search for publications between 1990 and 2017. Immune checkpoint inhibitors are designed to treat system malignancies by targeting one of three ligands, leading to T-cell activation for attack against malignant cells. These ligands (and targeted drug) include cytotoxic T-lymphocyte antigen-4 (CTLA-4, ipilimumab), programmed death protein 1 (PD-1, pembrolizumab, nivolumab), and programmed death ligand-1 (PD-L1, atezolizumab, avelumab, durvalumab). These medications upregulate the immune system and cause autoimmune-like side effects. Ophthalmic side effects most frequently manifest as uveitis (1%) and dry eye (1-24%). Other side effects include myasthenia gravis (n = 19 reports), inflammatory orbitopathy (n = 11), keratitis (n = 3), cranial nerve palsy (n = 3), optic neuropathy (n = 2), serous retinal detachment (n = 2), extraocular muscle myopathy (n = 1), atypical chorioretinal lesions (n = 1), immune retinopathy (n = 1), and neuroretinitis (n = 1). Most inflammatory side effects are managed with topical or periocular corticosteroids, but advanced cases require systemic corticosteroids and cessation of checkpoint inhibitor therapy. Checkpoint inhibitors enhance the immune system by releasing inhibition on T cells, with risk of autoimmune-like side effects. Ophthalmologists should include immune-related adverse events in their differential when examining cancer patients with new ocular symptoms.

2017-11-01

To compare efficacy, side effects, patient compliance, and preference between two types of custom-made mandibular advancement appliances (MAAs) in the treatment of patients with mild to moderate obstructive sleep apnea (OSA). This prospective, randomized, crossover study of 12 patients with mild to moderate OSA compared a titratable and a non-titratable MAA. Each patient was fitted with both appliances in a random order with a washout period of two weeks. Efficacy, side effects, compliance, and preference were evaluated by a questionnaire. All patients underwent overnight home sleep recordings prior to and after the use of each appliance in order to objectively assess sleep quality in terms of the apnea and hypopnea index (AHI), snoring frequency and oxygen desaturation index. Treatment successes (relief of symptoms and/or reduction of AHI to <10/h) were reported with both types of appliances. No compliance failure was reported, and in most patients, the side effects were mild, and improved with time. Both types of oral appliances were effective treatments for patients with mild to moderate OSA, with fewer side effects and higher patient satisfaction.

Ocular side effects of biological agents in oncology: what should the clinician be aware of?

PubMed Central

Hager, Tobias; Seitz, B

2014-01-01

During the last 20 years, biologicals have become increasingly relevant in oncologic therapy. Depending on the medication used, there are different profiles of ocular side effects. Although these can be present in up to 70% of patients, they are generally underreported in the literature. Therefore, the pathophysiological details of their development are often poorly understood. Herein we attempt to identify groups of biologicals to which a specific side effect profile can be assigned. We also tried to capture all relevant side effects and therefore conducted several database investigation including Medline, Cochrane library, and the drugs section of the US Food and Drug Administration (FDA), using the following search strings: “name of biological agent (both generic and commercial names)” AND “eye” OR “ocular”. If we found a side effect that has been associated with a drug, we researched Medline using the following search string: “name of biological agent” (both generic and commercial names) AND “term for the specific side effect”. Due to the wealth of material we report only the drugs that are approved by the FDA. PMID:24391443

To systematically review the effectiveness of medical treatment for Cushing's syndrome in clinical practice, regarding cortisol secretion, clinical symptom improvement, and quality of life. To assess the occurrence of side effects of these medical therapies. Eight electronic databases were searched in March 2017 to identify potentially relevant articles. Randomized controlled trials and cohort studies assessing the effectiveness of medical treatment in patients with Cushing's syndrome, were eligible. Pooled proportions were reported including 95% confidence intervals. We included 35 articles with in total 1520 patients in this meta-analysis. Most included patients had Cushing's disease. Pooled reported percentage of patients with normalization of cortisol ranged from 35.7% for cabergoline to 81.8% for mitotane in Cushing's disease. Patients using medication monotherapy showed a lower percentage of cortisol normalization compared to use of multiple medical agents (49.4 vs. 65.7%); this was even higher for patients with concurrent or previous radiotherapy (83.6%). Mild side effects were reported in 39.9%, and severe side effects were seen in 15.2% of patients after medical treatment. No meta-analyses were performed for clinical symptom improvement or quality of life due to lack of sufficient data. This meta-analysis shows that medication induces cortisol normalization effectively in a large percentage of patients. Medical treatment for Cushing's disease patients is thus a reasonable option in case of a contraindication for surgery, a recurrence, or in patients choosing not to have surgery. When experiencing side effects or no treatment effect, an alternate medical therapy or combination therapy can be considered.

Background Patients trying life-preserving agents such as beta-blockers may be discouraged by listings of harmful effects provided in good faith by doctors, drug information sheets, and media. We systematically review the world experience of side-effect information in blinded, placebo-controlled beta-blockade in heart failure. We present information for a physician advising a patient experiencing an unwanted symptom and suspecting the drug. Methods We searched Medline for double-blinded randomized trials of beta-blocker versus placebo in heart failure reporting side-effects. We calculated, per 100 patients reporting the symptom on beta-blockade, how many would have experienced it on placebo: the “proportion of symptoms non-pharmacological”. Results 28 of the 33 classically-described side-effects are not significantly more common on beta-blockers than placebo. Of the 100 patients developing dizziness on beta-blockers, 81 (95% CI 73–89) would have developed it on placebo. For diarrhoea this proportion is 82/100 (70–95), and hyperglycaemia 83/100 (68–98). For only two side-effects is this under half (i.e. predominantly due to beta-blocker): bradycardia (33/100, CI 21–44) and intermittent claudication (41/100, 2–81). At least 6 so-called side-effects are less common on beta-blocker than placebo, including depression (reduced by 35%, p < 0.01) and insomnia (by 27%, p = 0.01). Conclusions Clinicians might reconsider whether it is scientifically and ethically correct to warn a patient that a drug might cause them a certain side-effect, when randomized controlled trials show no significant increase, or indeed a significant reduction. A better informed consultation could, in patients taking beta-blockers, alleviate suffering. In patients who might otherwise not take the drug, it might prevent deaths. PMID:23796325

Nicotine replacement therapy (NRT) significantly increases the likelihood of quit success at least over the short term, yet some smokers prematurely discontinue use. NRT side effects are often cited as the primary reason for medication discontinuation. The current study examined a theoretical pathway by which two smoking-related emotional vulnerabilities (anxiety sensitivity and emotion dysregulation) were related to the number of NRT (nicotine patch) side effects reported 1 week following a scheduled quit attempt. It was hypothesized that anxiety sensitivity would have an indirect effect on NRT side effects through emotion dysregulation. A total of 179 treatment-seeking, adult daily smokers with elevated anxiety sensitivity (47.5% male; M age = 39.73 years, SD = 13.87) were enrolled in a smoking cessation trial. Covariate-adjusted analyses provided support for the hypothesized pathway, such that emotion dysregulation explained the association between anxiety sensitivity and NRT side effects (b = 0.02, SE = 0.01, 95% CI [0.002, 0.03]; completely standardized estimate = .15). The findings underscore the importance of developing cessation treatments that incorporate techniques to enhance emotion regulation, particularly among smokers higher in anxiety sensitivity, to decrease the risk of NRT side effects.

Patients with treatment-resistant obsessive-compulsive disorder (OCD) are potential candidates for deep brain stimulation (DBS). The anteromedial subthalamic nucleus (STN) is among the most commonly used targets for DBS in OCD. We present a patient with a 30-year history of treatment-resistant OCD who underwent anteromedial STN-DBS. Despite a clear mood-enhancing effect, stimulation caused motor side effects, including bilateral hyperkinesia, dyskinesias, and sudden large amplitude choreatic movements of arms and legs when stimulating at voltages greater than approximately 1.5 V. DBS at lower amplitudes and at other contact points failed to result in a significant reduction of obsessions and compulsions without inducing motor side effects. Because of this limitation in programming options, we decided to reoperate and target the ventral capsule/ventral striatum (VC/VS), which resulted in a substantial reduction in key obsessive and compulsive symptoms without serious side effects. Choreatic movements and hemiballismus have previously been linked to STN dysfunction and have been incidentally reported as side effects of DBS of the dorsolateral STN in Parkinson disease (PD). However, in PD, these side effects were usually transient, and they rarely interfered with DBS programming. In our patient, the motor side effects were persistent, and they made optimal DBS programming impossible. To our knowledge, such severe and persistent motor side effects have not been described previously for anteromedial STN-DBS. Copyright © 2017 Elsevier Inc. All rights reserved.

A novel recommendation-based drug repositioning strategy is presented to simultaneously determine novel drug indications and side effects in one integrated framework. This strategy provides a complementary method to medical genetics-based drug repositioning, which reduces the occurrence of false positives in medical genetics-based drug repositioning, resulting in a ranked list of new candidate indications and/or side effects with different confidence levels. Several new drug indications and side effects are reported with high prediction confidences. © 2015 American Society for Clinical Pharmacology and Therapeutics.

Objective: To explore the impact of patient reported outcome of tyrosine kinase inhibitor (TKI) related side effects on daily life in Chinese patients with chronic myeloid leukemia (CML) in the chronic phase (CP). Methods: From May to November in 2014, anonymous questionnaires were distributed to adult CML patients who were receiving TKI treatment in China. The impact of TKI-related side effects on daily life were assessed by the score of 1 (no impact) to 5 (high impact) from patient self-report. Results: Data from 731 respondents in the CP who reported the score of the impact of TKI-related side effects on daily life were collected. 407 (56%) were male. The median age was 41 years (range, 18 to 88 years). 560 (77%) started TKI treatment within 1 year after diagnosis. With a median treatment duration of 3 years (range, <1 to 13 years), 549 (75% ) respondents achieved a complete cytogenetic response (CCyR) and 301 (41%) achieved a complete molecular response (CMR). The most common TKI-related adverse effects were edema ( n =323, 44% ), fatigue ( n =277, 38% ), gastrointestinal disorders ( n =235, 32% ), skin color changes ( n =142, 19% ), muscle cramps ( n =137, 19% ), rash ( n =105, 14% ), hepatic function abnormalities ( n =91, 12%), weight gain ( n =86, 12%), and cytopenia ( n =59, 8%). Multivariate analyses showed that TKI treatment duration <4 years was the factor associated with fatigue; Edema was more observed in female, ≥40 years old and use of 1st generation TKI; Gastrointestinal disorders in use of 1st generation TKI; Hepatic function abnormalities and rash in use of 2nd generation TKI; Weight gain in female; Muscle cramps in long-term interval from diagnosis to therapy and use of 1st generation TKI; Low blood counts in use of generic TKI. There was no impact of TKI-related side effects on daily life in 218 (30%)respondents (1 score). 375 (51%)respondents reported their daily life were slightly or moderately decreased (2 or 3 score), while 138 (19%) significantly decreased (4 or 5 score). Multivariate analyses showed that female, ≥40 years old, use of generic TKI, TKI treatment duration <4 years were factors associated with negative effect on their daily life. When taking TKI related side-effects into considderation, secondary school and below, use of generic TKI, TKI treatment duration <4 years, edema, fatigue, gastrointestinal disorders, skin color changes, rash and hepatic function abnormalities, were factors associated with negative effect on their daily life. Conclusion: Edema, fatigue, gastrointestinal disorders, rash, skin color changes and hepatic function abnormalities were common TKI-related side effects and influenced CML patients' daily life in China. In addition, female, older age, lower education level, use of generic TKI and shorter TKI treatment duration were associated with negative impact on quality of life.

Optimal antiepileptic drug treatment in patients with learning disability (LD) represents a particular challenge. These patients are often unable to report toxicity, and side effects may manifest as behavioral problems. The aim of this open study was to compare efficacy and tolerability of levetiracetam (LEV) in patients with LD and those without LD. One hundred eighty-four consecutive adult patients who received LEV were followed for an average of 8.1 months. Fifty-six patients (30%) had LD. Thirty-nine percent of patients with refractory epilepsy (37% with and 40% without LD) had > 50% seizure reduction. Significantly more behavioral side effects (23% vs 10%) and a tendency toward less reported somatic central nervous side effects were found in the LD group. We conclude that LEV is equally effective and well tolerated in both patients with LD and patients without LD. However, behavioral problems are more frequent in patients with LD, whereas the tendency toward seizure increase is not enhanced.

Side effects of pharmacotherapy on bone with long-acting gonadorelin agonist triptorelin for paraphilia.

There have been limited research studies concerning the use of libido inhibitors for the treatment of patients with a paraphilia. Observational studies suggest that agents that lower testosterone are an effective treatment for paraphilia. We report a case of hormonal treatment of paraphilia that was associated with side effects. A 35-year-old man with a paraphilia was treated with long-acting gonadorelin. The desired result was reduced preoccupation with sexuality, but there were various side effects including a serious amount of bone loss. We believe that more attention should be given to the adverse effects of long-term treatment with triptorelin. In our view the drug regime needs to be revised.

There are few studies describing psychiatric symptoms occurring when methylphenidate and disulfiram are used together. The authors report a case of disulfiram and methylphenidate interaction in which psychotic symptoms could be dose dependent. The patient, diagnosed of alcohol and cocaine dependence and attention deficit hyperactivity disorder (ADHD), started treatment with methylphenidate increasing doses and disulfiram 250 mg/day over 4 weeks. During the first 2 weeks at doses of 36 mg/day of methylphenidate and maintaining disulfiram, side effects were not observed. However, by increasing to 54 mg/day, psychotic symptoms were detected. The authors reported that the effects are dose dependent. This is the first report about dose-dependent side effects in substance use disorder with ADHD.

Antidepressant-associated sexual dysfunction: impact, effects, and treatment

2010-01-01

Sexual dysfunction is a common side effect of antidepressants and can have significant impact on the person’s quality of life, relationships, mental health, and recovery. The reported incidence of sexual dysfunction associated with antidepressant medication varies considerably between studies, making it difficult to estimate the exact incidence or prevalence. The sexual problems reported range from decreased sexual desire, decreased sexual excitement, diminished or delayed orgasm, to erection or delayed ejaculation problems. There are a number of case reports of sexual side effects, such as priapism, painful ejaculation, penile anesthesia, loss of sensation in the vagina and nipples, persistent genital arousal and nonpuerperal lactation in women. The focus of this article is to explore the incidence, pathophysiology, and treatment of antidepressant iatrogenic sexual dysfunction. PMID:21701626

64 women clients of Planned Parenthood of Evansville (Indiana) used Enovid (5 mg norethynodrel and .075 mg mestranol, combined) for 2 1/2 to 6 years. A "25-Month Club" card and free pills were given to encourage continuation in the study, and 33 women (52%) remained until study termination. The group ranged in age from 18-40 years, mean 27 years, and in parity 0 to 12, mean 4. No pregnancies, cancer of reproductive organs or thromboembolism occurred. Side effects, recorded by interview according to a standard form, included: cervicitis 48%, vaginal discharge 42%; dysmenorrhea 61% pretreatment, 42% improved, 11% new symptoms; breast complaints 33%; 2-15 lb weight gain 19%. 12% reported no side effects, although the author commented that the 25-Month Club policy might have discouraged reporting of side effects.

Some studies have reported the use of 308-nm excimer laser therapy for treating alopecia areata (AA); however, the effectiveness of this therapy on a theoretical basis has not yet been comparatively analyzed. To determine the therapeutic effect of excimer laser therapy on AA. One alopecic patch was divided into control and treated sides in 10 patients with AA. Then, 308-nm excimer laser therapy was administered twice a week for 12 weeks. Photograph and phototrichogram analyses were performed. Photographic assessments by both dermatologists and individuals of the general population showed objective improvements after excimer laser therapy. On the treated side, the hair count and hair diameter had statistically increased after treatment. However, only the hair diameter was found to be significantly high in the treated half when it was compared with the control side. The 308-nm excimer laser has a therapeutic effect on AA, which is proven by photograph and phototrichogram analysis by a side-by-side comparison. © 2015 S. Karger AG, Basel.

The Oxford Questionnaire on the Emotional Side-effects of Antidepressants (OQuESA): development, validity, reliability and sensitivity to change.

PubMed

Price, Jonathan; Cole, Victoria; Doll, Helen; Goodwin, Guy M

2012-09-01

Some patients with major depression report a restricted range of emotions that may appear to arise as a side-effect of treatment with antidepressants. It is uncertain whether this phenomenon, sometimes called emotional blunting, represents residual symptoms of depression or side-effects of antidepressant treatment. There is currently no adequate instrument to measure this phenomenon. A draft questionnaire was developed from patient-derived qualitative data, refined using cognitive interviewing, and administered on three occasions to patients taking antidepressants. Statistical methods including factor analysis were used to reduce the size of the draft questionnaire, and to assess the performance of the resulting Oxford Questionnaire on the Emotional Side-effects of Antidepressants (OQuESA). 207 patients completed the OQuESA on at least one occasion. Their BDI-II scores and self-reported emotional blunting were spread across the possible range. The factor analysis resulted in four dimensions: 'not caring', 'emotional detachment', 'reduction in positive emotions', and 'general reduction in emotions'. The OQuESA appears to be acceptable, valid, and reliable, with sensitivity to change. The OQuESA offers promise as an effective self-report measure of the symptoms of emotional blunting in patients with depression. It can be used as a clinical tool, to facilitate the identification of patients with the syndrome of emotional blunting. It should also be used in research studies, to advance our understanding of the nature, causes and treatment of this phenomenon. Copyright © 2012 Elsevier B.V. All rights reserved.

Effects of 5-alpha reductase inhibitors on erectile function, sexual desire and ejaculation.

Gur, Serap; Kadowitz, Philip J; Hellstrom, Wayne Jg

2013-01-01

Treatment with 5-alpha reductase inhibitors (5ARI) is commonly utilized for the treatment of benign prostatic hyperplasia (BPH). The true prevalence of sexual side effects with 5ARI treatment is currently unknown. The current article reviews the reported adverse effects of 5ARI in regard to erectile function, sexual desire and ejaculation. A PubMed search was performed of all articles from 1990 to present, which reported any sexual side effects with finasteride or dutasteride. Preference was given to more recent and human studies where available. Clinical trials with 5ARI report prevalence rates of de novo erectile dysfunction of 5 - 9%. Decreased circulating dihydrotestosterone (DHT) resulting from 5ARI use is associated with diminished sexual desire and/or orgasm. The presence of adverse sexual effects is associated with decreased self-esteem, quality of life and ability to maintain an intimate relationship. Inhibition of 5ARI additionally influences progesterone and deoxycorticosterone levels and may alter psychological functions, including increased depression, melancholy and loss of general well being. Ejaculatory dysfunction has not been well studied in patients using 5ARI. Patients receiving therapy with 5ARI should be counseled as to potential sexual and psychological adverse effects. Future clinical studies are needed to further investigate the sexual side effects associated with this class of drugs.

Type and frequency of side effects during PC6 acupuncture: observations from therapists and patients participating in clinical efficacy trials of acupuncture.

Many therapists practise PC6 acupuncture for emesis (nausea and vomiting) during pregnancy, different cancer therapies, palliative care, after surgery, or to induce relaxing effects in general. Knowledge of side effects is central to shared decision-making. To describe the type and frequency of side effects and the level of needle-induced pain during PC6 acupuncture. We included 1298 PC6 acupuncture treatments, delivered to 221 participants (77% women, mean age 52.5, range 18-91 years). The subjects had received genuine PC6 acupuncture, in one of two previous randomised controlled trials, aimed at inducing antiemetic (n=100, with 100 providing data on side effects and 94 on needle-induced pain, respectively) or relaxing (n=121, with 120 providing data) effects. Side effects during and after the acupuncture treatments were registered in structured treatment protocols and study diaries. No serious complications occurred. Side effects during the acupuncture sessions included minor bleeding in 5.0%, tiredness in 4.9%, numbness in 4.5% and dizziness in 1.4% of the 1298 treatments. After treatment, the mean proportions of participants reporting side effects each week were: tiredness 25.8%; feeling cold 17.8%; dizziness 9.7%; sweating 9.3%; haematoma 8.8%; and soreness at the needling sites 4.3%. Participants perceived the needling to be not painful (47.4% of participants), or mildly (39.1%), moderately (11.6%) or very painful (1.4%). Few side effects occurred and those that did were mild. Nearly 90% found PC6 acupuncture to be not painful or only mildly painful. Healthcare professionals may consider the observed levels of side effects when informing patients about side effects of PC6 acupuncture. © Article author(s) (or their employer(s) unless otherwise stated in the text of the article) 2017.

Kombucha tea is a health beverage made by incubating the Kombucha “mushroom” in tea and sugar. Although therapeutic benefits have been attributed to the drink, neither its beneficial effects nor adverse side effects have been reported widely in the scientific literature. Side effects probably related to consumption of Kombucha tea are reported in four patients. Two presented with symptoms of allergic reaction, the third with jaundice, and the fourth with nausea, vomiting, and head and neck pain. In all four, use of Kombucha tea in proximity to onset of symptoms and symptom resolution on cessation of tea drinking suggest a probable etiologic association. PMID:9346462

Objective: Clozapine is a second-generation antipsychotic used for treatment-resistant schizophrenia. Despite its effectiveness, clozapine is largely underused due to serious side effects such as leukopenia or neutropenia. We aimed to review whether to continue, discontinue or rechallenge clozapine treatment after such haematological side effects. Methods: We reviewed and summarized the literature on the use of clozapine, how to deal with its side effects, and suitable options in case of any haematological problems. Then, we described several cases successfully treated with clozapine and lithium after development of neutropenia or leukopenia Results: We present three patients with treatment-resistant schizophrenia. While they had demonstrated poor response to multiple antipsychotic trials, clozapine was started. Clozapine induced neutropenia; or leukopenia developed in some cases that was successfully reversed after lithium onset. Increased serious side effects related with coprescription of lithium and clozapine were not observed. Conclusion: Lithium increases neutrophil and total white blood cell count as a side effect that may be useful in patients who develop neutropenia or leukopenia while being treated with clozapine.

Abstract Introduction Sexual dysfunction is a well‐known side effect of antidepressants. Painful ejaculation is a rare side effect that has been reported with the use of some psychiatric drugs such as triclyclic antidepressants. Cyclobenzaprine is a muscle relaxant that is structurally similar to tricyclic antidepressants. It is the most commonly prescribed muscle relaxant in the United States and accounts for 18% of all prescriptions written for chronic back pain. Methods A 55‐year‐old man was referred to our pain medicine clinic for evaluation and treatment of pain with ejaculation. Main outcome Measure The main outcome measure was to review the current published literature and case reports on painful ejaculation from medication use, in particular tricyclic antidepressants. Results After discontinuation of cyclobenzaprine, our patient's sexual dysfunction resolved. This result was consistent with the literature reviewed on the topic. Conclusion Painful ejaculation is likely an underreported side effect of tricyclic antidepressants and cyclobenzaprine use. Fortunately, these symptoms are reversible and discontinuation of these medications is typically an effective cure. K raus MB , W ie CS , G orlin AW , W isenbaugh ES , and R osenfeld DM .

A 6-year-old, large-breed, female dog was evaluated for gastric dilatation (GD). The dog was affected by GD volvulus, which had been surgically treated with gastric derotation and right incisional gastropexy. Recurrence of GD appeared 36 hours after surgery. The dilatation was immediately treated with an orogastric probe but still recurred 4 times. Therefore, a left-side gastropexy by percutaneous endoscopic gastrostomy (PEG) was performed to prevent intermittent GD. After PEG tube placement, the patient recovered rapidly without side effects. Several techniques of gastropexy have been described as a prophylactic method for gastric dilatation volvulus, but to the authors' knowledge, this is the first report of left-sided PEG gastropexy performed in a case of canine GD recurrence after an incisional right gastropexy.

Continuous prostaglandin-F 2 infusion for middle-trimester abortion.

Lauersen, N H; Wilson, K H

1973-05-26

Induction of midtrimester abortion with a continuous intravenous infusion of prostaglandin (PG) was described by Karim and Filshie and Roth-Brandel et al. in 1970, but the effective dose of PGF2alpha was associated with side effects severely limiting clinical usefulness. Karim and Sharma induced abortion by intravaginal PG, but again this route also seemed complicated by severe side effects. Independent reports followed of successful induction of midtrimester abortion by intraamniotic PGF2alpha and PGE2 with few side effects. Although we also successfully induced abortion in 20 patients with a single intraamniotic instillation of 40 mg PGF2alpha, there is a potential hazard in this method; i.e., PG may leak from the amniotic cavity around the catheter and pass in large quantity into the systemic circulation, resulting in undesirable, severe side effects. A more reasonable and effective method would be to inject the PGF2alpha directly at the target organ, the myometrium, by extraovular administration. Side effects could thus be minimized and effective doses of PG reduced. Such intrauterine extraovular administration of PG has been reported. The incidence of side effects was greatly reduced, although the instillation of PG was required every 1-3 hours and there were some incomplete abortions. The investigation of extraovular PGF2alpha administration for induction of abortion in gestations between 12 and 16 weeks has been especially interesting. The procedure outlined by Wiqvist and Bygdeman and Embrey and Hillier was the 1 that the authors followed initially. 250 mcg PGF2alpha was instilled initially and was followed by 750 mcg in 5 minutes and 1 mg in 30 minutes. 1 mg was then instilled at 6 hour intervals. However, the failure rate with this dosage schedule was quite high. There was a good initial uterine response, but during the administrationsat 12, 18, and 24 hours, the response diminished considerably . The frequency of administration was then increased to every 2-3 hours and the amount instilled was increased to 2-3 mg. Although somewhat more successful than the original dose schedule, this method was also unsatisfactory. It appeared from our results that the closer the injections, the higher the success rate. Thus, a brief case report is presented using continuous extraovular administration of PGF2alpha with a Harvard pump, and the results indicate it is quite satisfactory. The patients complained of very little pain and side effects have been slight. The mean abortion time for 15 patients was 14 hours. The mean time for multiparas, 11.7 hours, was faster than the 15.8 hours for primiparas.

To study cycle control, side effects, and satisfaction of low dose 24-day combined contraceptive containing 20 microg of Ethinylestradiol and 3 mg of Drospirenone. This was an open label, non-comparative study. The healthy females from the family planning clinic at King Chulalongkorn Memorial Hospital were assigned to receive six cycles of combined oral contraceptive containing 20 microg of ethinylestradiol and 3 mg of drospirenone administered daily for 24 days followed by 4-day hormone-free interval. Data were collected on cycle control, side effects, and satisfaction. Data were analyzed using descriptive statistics for descriptive data and Paired t test for comparison. One hundred fifty four women were assigned the study medication, including one (0.64%) who did not start medication. In the second reference period, the occurrence of frequent and infrequent bleeding was low (2.1% and 4.9%). Only one woman (0.65%) discontinued medication because of irregular bleeding. There was no pregnancy reported during the present study. Overall, the study medication was well tolerated and five subjects (3.24%) discontinued study because of side effects. No serious side effects related to the study medication were reported. The majority of women (84.2%) were satisfied and very satisfied with the treatment and most (73.3%) would continue the medication if it were available. The low dose combined contraceptive containing Ethinylestradiol/Drospirenone (24/4 regimen) has acceptable cycle control and good tolerability.

Gastrointestinal stromal tumors (GISTs) are uncommon tumors of the gastrointestinal (GI) tract. Regorafenib is a new multikinase inhibitor and is approved for the treatment of GISTs in patients who develop resistance to imatinib and sunitinib. The most common drug-related adverse events with regorafenib are hypertension, hand-foot skin reactions, and diarrhea. Grade IV hypertensive side effect has never been reported after a single dose. In this report, we present a case of Grade IV hypertensive side effect (hypertensive crisis and seizure) after a single dose of regorafenib. A 54-year-old male normotensive GIST patient was admitted to the emergency department with seizure and encephalopathy after the first dosage of regorafenib. His blood pressure was 240/140 mmHg upon admission. After intensive treatment with nitrate and nitroprusside, his blood pressure returned to normal levels in five days. Regorafenib was discontinued, and he did not experience hypertension again. This paper reports the first case of Grade IV hypertension after the first dosage of regorafenib. We can suggest that hypertension is an idiosyncratic side effect unrelated to the dosage.

Antiretroviral therapy (ART) is a lifelong treatment. To date, ART adherence is suboptimal for most patients in resource-poor settings. Previous research indicates that medication side effects are perceived to be a significant barrier of high ART adherence. Data regarding the role of adherence self-efficacy in mediating the relationship between side effects from ART and adherence to ART are limited; thus, this study examines this potential mediational role of self-efficacy. A cross-sectional survey of 2987 people living with HIV aged ≥18 years was conducted in 2012-2013 in Guangxi Autonomous Region (Guangxi) which has one of the fastest-growing HIV rates in China. Of the total sample, 2146 (72.1%) participants had initiated ART. Participants reported the number of days of completing the daily dose of ART in the past month; adherence was defined as completing the daily dose at least 28 days in the last month (≥90%). Side effects were significantly negatively related to adherence to ART. Mediation analyses indicated that adherence self-efficacy significantly mediated the side effects-adherence relationship. Future interventions to increase adherence self-efficacy and effective coping with side effects among HIV patients are needed in order to improve their ART adherence.

Background. Cancer patients using cannabis report better influence from the plant extract than from synthetic products. However, almost all the research conducted to date has been performed with synthetic products. We followed patients with a medicinal cannabis license to evaluate the advantages and side effects of using cannabis by cancer patients. Methods. The study included two interviews based on questionnaires regarding symptoms and side effects, the first held on the day the license was issued and the second 6-8 weeks later. Cancer symptoms and cannabis side effects were documented on scales from 0 to 4 following the CTCAE. The distress thermometer was used also. Results. Of the 211 patients who had a first interview, only 131 had the second interview, 25 of whom stopped treatment after less than a week. All cancer or anticancer treatment-related symptoms showed significant improvement (P < 0.001). No significant side effects except for memory lessening in patients with prolonged cannabis use (P = 0.002) were noted. Conclusion. The positive effects of cannabis on various cancer-related symptoms are tempered by reliance on self-reporting for many of the variables. Although studies with a control group are missing, the improvement in symptoms should push the use of cannabis in palliative treatment of oncology patients.

Topical tretinoin is a medication commonly used for acne that has potential application in the long-term treatment of photodamaged skin. However, there are few published data regarding the tolerability of high-dose tretinoin with long-term use. To assess the long-term tolerability of tretinoin 0.1% cream. A randomized, multicentre, double-blind, controlled trial for chemoprevention of keratinocyte carcinomas (i.e. basal cell or squamous cell carcinomas) using topical tretinoin cream to the face and ears was conducted. All participants were veterans and had a history of two or more keratinocyte carcinomas over the previous 5 years. Participants were examined (by a study dermatologist) and interviewed every 6 months (for up to 5.5 years to May 2004). Treatment comprised tretinoin 0.1% cream or vehicle control cream once daily, then twice daily as tolerated. Participants were instructed to step down application frequency to once daily or less if twice daily was not tolerated. The main outcome measures were reported side-effects, frequency of cream application and attendance at study visits. Appropriate data were available for four of the six clinical sites of this trial. Data from 736 randomized participants (mean age 71 years; 97% men) from four clinical sites were analysed. The tretinoin group more commonly reported one or more side-effects at the 6-month follow-up than the control group (61% vs. 42%, P < 0.0001). Side-effects decreased over time in both groups, but to a greater extent in the tretinoin group, and the difference became nonsignificant at 30 months. Burning was the most common side-effect (39% tretinoin vs. 17% control, P < 0.0001). There was no difference in severity of side-effects among those affected. Of the participants who reported burning in either group, most reported mild burning; only 11% of those with burning in the tretinoin group reported it as severe (mild 62% tretinoin vs. 70% placebo; severe 11% vs. 5%; P = 0.4). Itching (24% vs. 16%, P = 0.01) and other local cutaneous reactions (12% vs. 6%, P = 0.01) were also more commonly reported by the tretinoin group at 6 months. There was no difference in numbness (2% vs. 2%, P = 0.9). Participants in the tretinoin group were less likely to apply cream twice daily at 6 months (29% vs. 43%, P = 0.0002). This difference persisted over the entire duration of follow-up. There was little difference between groups in attendance at study visits or completion of telephone interviews (92% vs. 95%, P = 0.06). No unexpected adverse events were reported. Overall, the tolerability level of topical tretinoin was high in this study population, with almost 40% of the tretinoin group reporting no side-effects, and the majority (67%) tolerating at least once-daily dosing at 6-month follow-up. High-dose topical tretinoin is feasible for long-term use in this population.

Consumer surveys provide information on effectiveness and side effects of medical interventions in routine clinical care. A report of fibromyalgia syndrome (FMS) consumers has not been carried out in Europe. The study was carried out from November 2010 to April 2011. Participants diagnosed with FMS rated the effectiveness and side effects of pharmacological and non-pharmacological FMS interventions on a 0 to 10 scale, with 10 being most efficacious (harmful). The questionnaire was distributed by the German League for people with Arthritis and Rheumatism and the German Fibromyalgia Association to their members and to all consecutive FMS patients of nine clinical centers of different levels of care. 1661 questionnaires (95% women, mean age 54 years, mean duration since FMS diagnosis 6.8 years) were analysed. The most frequently used therapies were self-management strategies, prescription pain medication and aerobic exercise. The highest average effectiveness was attributed to whole body and local warmth therapies, thermal bathes, FMS education and resting. The highest average side effects were attributed to strong opioids, local cold therapy, gamma-amino-butyric acid analogues (pregabalin and gabapentin), tramadol and opioid transdermal systems. The German fibromyalgia consumer reports highlight the importance of non-pharmcological therapies in the long-term management of FMS, and challenges the strong recommendations for drug therapies given by FMS-guidelines.

Q-switched laser treatments are considered the standard method for removing both regular and traumatic tattoos. Recently, the removal of tattoo ink using ablative fractional lasers has been reported. Ablative fractional CO2 laser and q-switched ruby laser treatments were used in a split-face mode to compare the safety and efficacy of the two types of laser in removing a traumatic tattoo caused by the explosion of a firework. A male patient suffering from a traumatic tattoo due to explosive deposits in his entire face was subjected to therapy. A series of eleven treatments were performed. The right side of the face was always treated using an ablative fractional CO2 laser, whereas the left side was treated only using a q-switched ruby laser. After a series of eleven treatments, the patient demonstrated a significant lightening on both sides of his traumatic tattoo, with no clinical difference. After the first six treatments, the patient displayed greater lightening on the right side of his face, whereas after another five treatments, the left side of the patient's face appeared lighter. No side effects were reported. In the initial stage of removing the traumatic tattoo, the ablative fractional laser treatment appeared to be as effective as the standard ruby laser therapy. However, from the 6th treatment onward, the ruby laser therapy was more effective. Although ablative fractional CO2 lasers have the potential to remove traumatic tattoos, they remain a second-line treatment option.

The high rate of relapse of acne lesions following oral isotretinoin treatment is a common problem which remains unsolved. To avoid or minimize relapses, topical retinoids have been used for many years as maintenance treatment. However, adverse effects frequently occur. To determine the efficacy and safety of a new retinoid combination (Retinsphere technology) in maintaining post-treatment response to oral isotretinoin. Prospective, randomized, double-blind and vehicle-controlled study of 30 patients with acne previously treated with isotretinoin. Treatment with the retinoid combination was applied to one side of the face and vehicle was applied to the other, once daily, for 3 months. Standardized photographs were taken using RBX technology at baseline, 1.5 months and 3 months. The primary efficacy endpoint was the appearance of relapse on the treated side compared to the vehicle-treated side. Other endpoints included lesion count, investigator-reported improvement, patient-reported improvement, impact on quality-of-life, and side effects. Although the majority of patients did not reach the total target dose of oral isotretinoin, the relapse rate was significantly lower on the retinoid-treated side compared to the vehicle-treated side. Likewise, improved lesion count and excellent tolerance were observed. This new retinoid combination (Retinsphere technology) were effective and safe as maintenance therapy after post-treatment response to oral isotretinoin in patients with acne.

To test patients' knowledge of side effects after they review six easy-to-read pamphlets on radiation side effects. Nonexperimental. Urban radiation oncology clinic. 47 patients receiving radiation treatment. The Knowledge of Radiation Side Effects Test was administered. Patient literacy and knowledge level. The self-report of highest grade completed in school was 10th grade; however, the actual reading level was 4th-6th grade. Scores for each knowledge test increased with literacy level, with statistically significant correlations for pamphlets on fatigue, skin problems for women, and skin problems for men. Participants who read at the 4th-6th-grade level scored higher than expected. Although the pamphlets were deemed easy to read, patients who had the lowest reading levels still had difficulty understanding them. In addition to written patient information, oncology nurses should use innovative teaching strategies to improve patient understanding and self-care behaviors. A need exists for continued nursing inquiry that will focus on self-care behaviors to manage radiation side effects, particularly for patients with low literacy.

This retrospective study evaluated the ocular side effects of cancer-bearing dogs and cats treated with external–beam Cobalt-60 (Co-60) radiation in which one or both orbit(s) were included in the radiation field. A total of 37 dogs and 12 cats presented to the Ontario Veterinary College during the 10-year study period (1999–2009) were evaluated. The radiation protocols ranged from a maximum of 60 Gray (Gy) in 24 fractions for curative intent to a minimum of 8 Gy in 1 fraction for palliative treatment. The main ocular side effect reported in both dogs and cats was conjunctivitis (79% and 55%, respectively). Other common ocular side effects included eyelid lesions in dogs (44%), ulcerative keratitis in cats (36%), and keratoconjunctivitis sicca in both dogs and cats (44% and 27%, respectively). The high incidence of ocular side effects in both patient populations indicates a need for regular ophthalmic examinations as a component of routine follow-up for radiation therapy involving the orbit. Radiation damage to ocular tissues is also reviewed. PMID:23729828

Characteristics of Articles About Human Papillomavirus Vaccination in Japanese Newspapers: Time-Series Analysis Study.

2017-12-19

Media coverage and reports have a major influence on individual vaccination and other health-related activities. People use the media to seek information and knowledge on health-related behaviors. They obtain health-related information from media such as television and newspapers, and they trust such information. While several studies have examined the relation between media coverage and individual health, there is a lack of studies that have analyzed media reports of health information. In particular, we have found no analyses related to cervical cancer (human papillomavirus [HPV]) vaccine. This study aimed to identify mentions of cervical cancer vaccine in Japan's printed news media and to determine their characteristics. We used the archival databases of 2 Japanese newspapers, Yomiuri Shimbun (Yomidasu Rekishikan) and Asahi Shimbun (Kikuzo II Visual), for text mining. First, we created a database by extracting articles published between January 1, 2007, and December 31, 2014, that matched the terms "cervical cancer" AND "vaccination" in a keyword search. Then, we tallied the extracted articles based on the month of publication and number of characters in order to conduct a time-series analysis. We extracted a total of 219 articles. Of these, 154 (70.3%) were positive and 51 (23.3%) were negative toward HPV vaccination. Of the 51 negative articles, 4 (7.8%) were published before June 2013, when routine vaccination was temporarily discontinued due to concerns regarding side effects, and 47 (92.2%) were published since then. The negative reports commonly cited side effects, although prior to June 2013, these issues were hardly mentioned. Although foreign media reports mentioned side effects before routine vaccination was temporarily discontinued, fewer articles mentioned side effects than recommendations for vaccination. Furthermore, on June 13, 2013, the World Health Organization's advisory body Global Advisory Committee on Vaccine Safety issued a statement regarding the safety of HPV vaccines, but hardly any articles reported this statement. Rather, several articles were published about the side effects after June 2013. Since we consider media coverage to be a factor affecting human health behavior, the media should extensively report on the cost of not receiving cervical cancer vaccination, global trends concerning cervical cancer vaccination, and statements released by various agencies on the subject. ©Nao Ueda, Ryoki Yokouchi, Taro Onoda, Atsushi Ogihara.

Nurses' discourse in contraceptive prescribing: an analysis using Foucault's 'procedures of exclusion'.

PubMed

Hayter, Mark

2007-05-01

This paper is a report of an analysis of the discourse about contraceptive efficacy and side effects used by nurses when prescribing contraception. All women seeking contraception should be informed of the efficacy and potential adverse effects of the particular method they are considering. This information facilitates an informed choice. Women also require this information in order to monitor for any side effects. Paradoxically, side effects are also a key factor in reducing adherence with contraceptive regimens. However, there is no literature that explores specifically how this issue is addressed in clinical consultations, or places these practices in a theoretical context. Forty-nine consultations between nurses and women in sexual health clinics were audio-recorded during 2002. Data were subject to a discourse analysis using Foucault's 'procedures of exclusion' to explore the discursive construction of contraceptive efficacy and side effects The nurses employed specific discursive strategies when discussing contraception. When addressing efficacy, discourse centred on medico-statistical facts, but side effects were described in lay terms that minimized their severity. Nurses contextualized contraceptive side effects within potential problems that women might experience in pregnancy, and also attempted to 'normalize' contraceptive-related problems. Discourse and its deployment play a key role in practitioner-client relationships that sexual health nurses need to become more aware of how they discuss clinical issues about contraception with women. Clinical data on contraceptive side-effects are present in the literature, and it is important that sexual health nurses use this to help women make truly informed decisions.

The Presentation Location of the Reference Stimuli Affects the Left-Side Bias in the Processing of Faces and Chinese Characters

PubMed Central

Li, Chenglin; Cao, Xiaohua

2017-01-01

For faces and Chinese characters, a left-side processing bias, in which observers rely more heavily on information conveyed by the left side of stimuli than the right side of stimuli, has been frequently reported in previous studies. However, it remains unclear whether this left-side bias effect is modulated by the reference stimuli's location. The present study adopted the chimeric stimuli task to investigate the influence of the presentation location of the reference stimuli on the left-side bias in face and Chinese character processing. The results demonstrated that when a reference face was presented in the left visual field of its chimeric images, which are centrally presented, the participants showed a preference higher than the no-bias threshold for the left chimeric face; this effect, however, was not observed in the right visual field. This finding indicates that the left-side bias effect in face processing is stronger when the reference face is in the left visual field. In contrast, the left-side bias was observed in Chinese character processing when the reference Chinese character was presented in either the left or right visual field. Together, these findings suggest that although faces and Chinese characters both have a left-side processing bias, the underlying neural mechanisms of this left-side bias might be different.

Women with ovarian cancer can have long overall survival and goals of treatment change over time from cure to remission to stable disease. We sought to determine whether survivors' acceptance of treatment side effects also changes over the disease continuum. Women with ovarian cancer completed an online survey focusing on survivors' goals and priorities. The survey was distributed through survivor networks and social media. Four hundred and thirty-four women visited the survey website and 328 (76%) completed the survey. Among participants, 141 (43%) identified themselves as having ever recurred, 119 (36%) were undergoing treatment at the time of survey completion and 86 (26%) had received four or more chemotherapy regimens. Respondents' goals of care were cure for 115 women (35%), remission for 156 (48%) and stable disease for 56 (17%). When asked what was most meaningful, 148 women (45%) reported overall survival, 135 (41%) reported quality of life and 40 (12%) reported progression-free survival. >50% of survivors were willing to tolerate the following symptoms for the goal of cure: fatigue (283, 86%), alopecia (281, 86%), diarrhea (232, 71%), constipation (227, 69%), neuropathy (218, 66%), arthralgia (210, 64%), sexual side effects (201, 61%), reflux symptoms (188, 57%), memory loss (180, 55%), nausea/vomiting (180, 55%), hospitalization for treatment side effects (179, 55%) and pain (169, 52%). The rates of tolerance for most symptoms decreased significantly as the goal of treatment changed from cure to remission to stable disease. Women with ovarian cancer willingly accept many treatment side effects when the goal of treatment is cure, however become less accepting when the goal is remission and even less so when the goal is stable disease. Physicians and survivors must carefully consider treatment toxicities and quality of life effects when selecting drugs for patients with incurable disease. Copyright © 2017 Elsevier Inc.

Continuous subcutaneous infusion of lidocaine for persistent hiccup in advanced cancer.

PubMed

Kaneishi, Keisuke; Kawabata, Masahiro

2013-03-01

Persistent hiccup can cause anorexia, weight loss, disabling sleep deprivation, anxiety, and depression. Therefore, relief of persistent hiccup is important for advanced cancer patients and their family. Most reports on this condition are case series reports advocating the use of baclofen, haloperidol, gabapentin, and midazolam. However, these medications are occasionally ineffective or accompanied by intolerable side effects. The sodium channel blocker lidocaine has been shown to be effective in treating a variety of disorders thought to involve neuropathic mechanisms. Intravenous administration of lidocaine is common but efficacy has also been reported for subcutaneous infusion. In advanced cancer patients, subcutaneous infusion is easy, advantageous, and accompanied by less discomfort. We report a case of severe and sustained hiccup caused by gastric cancer that was successfully treated with a continuous subcutaneous infusion of lidocaine (480 mg (24 ml)/day) without severe side effects.

Methylphenidate is a short-acting stimulant. In this article, the authors report a 7-year-old male patient who presented with orofacial and limb dyskinesia after his first dose of methylphenidate treatment for a diagnosis of attention-deficit/hyperactivity disorder; he was also receiving sodium valproate treatment for epilepsy. Orofacial dyskinesia appeared 5 hours after methylphenidate administration, persisted for 10 hours, and had completely resolved within 2 days. Although limb dyskinesia after methylphenidate is a commonly reported side effect, to the authors' knowledge this is only the second reported case to develop both orofacial and limb dyskinesia in the acute period after the first dose of methylphenidate. This case is reported to emphasize the potential side effects of methylphenidate, individual differences in drug sensitivities, and drug-receptor interactions via different mechanisms.

Effects of visual cue and response assignment on spatial stimulus coding in stimulus-response compatibility.

PubMed

Nishimura, Akio; Yokosawa, Kazuhiko

2012-01-01

Tlauka and McKenna ( 2000 ) reported a reversal of the traditional stimulus-response compatibility (SRC) effect (faster responding to a stimulus presented on the same side than to one on the opposite side) when the stimulus appearing on one side of a display is a member of a superordinate unit that is largely on the opposite side. We investigated the effects of a visual cue that explicitly shows a superordinate unit, and of assignment of multiple stimuli within each superordinate unit to one response, on the SRC effect based on superordinate unit position. Three experiments revealed that stimulus-response assignment is critical, while the visual cue plays a minor role, in eliciting the SRC effect based on the superordinate unit position. Findings suggest bidirectional interaction between perception and action and simultaneous spatial stimulus coding according to multiple frames of reference, with contribution of each coding to the SRC effect flexibly varying with task situations.

Kerato-lenticular ocular deposits and visual impairment with prolonged chlorpromazine use: A case series.

Chlorpromazine is a low potency "typical" antipsychotic agent used to treat schizophrenia. It continues to be prescribed frequently in India owing to its lower cost. There have been previous reports of ocular adverse effects with prolonged use of chlorpromazine. We report three patients who developed corneal and lenticular opacities secondary to prolonged chlorpromazine use leading to visual impairment. Early detection of ocular deposits and switching over to risperidone from chlorpromazine helped in the reversal of chlorpromazine- induced ocular side effects in one of them. The case series further adds evidence to the causative relationship between chlorpromazine and ocular side effects. Copyright © 2016 Elsevier B.V. All rights reserved.

We report three cases of multicentric Castleman's disease (MCD) successfully treated with anti-interleukin-6 receptor antibody (tocilizumab). Tocilizumab was administered intravenously at a dose of 8 mg/kg every 2 weeks. In each case, tocilizumab alleviated symptoms, including generalized fatigue, pyrexia, and alleviated biochemical abnormalities, including anemia, hypoalbuminemia, hypergammaglobulinemia, and increased C-reactive protein (CRP). Side effects included hypercholesterolemia, acute pyelonephritis, mild inflammation of the parotid glands, and upper respiratory system inflammation. Other severe side effects were not observed. These results indicate that tocilizumab is effective for the treatment of MCD. This is the first report on tocilizumab efficacy for Castleman's disease after approval for use for Castleman's disease.

Mining adverse drug reactions from online healthcare forums using hidden Markov model.

PubMed

Sampathkumar, Hariprasad; Chen, Xue-wen; Luo, Bo

2014-10-23

Adverse Drug Reactions are one of the leading causes of injury or death among patients undergoing medical treatments. Not all Adverse Drug Reactions are identified before a drug is made available in the market. Current post-marketing drug surveillance methods, which are based purely on voluntary spontaneous reports, are unable to provide the early indications necessary to prevent the occurrence of such injuries or fatalities. The objective of this research is to extract reports of adverse drug side-effects from messages in online healthcare forums and use them as early indicators to assist in post-marketing drug surveillance. We treat the task of extracting adverse side-effects of drugs from healthcare forum messages as a sequence labeling problem and present a Hidden Markov Model(HMM) based Text Mining system that can be used to classify a message as containing drug side-effect information and then extract the adverse side-effect mentions from it. A manually annotated dataset from http://www.medications.com is used in the training and validation of the HMM based Text Mining system. A 10-fold cross-validation on the manually annotated dataset yielded on average an F-Score of 0.76 from the HMM Classifier, in comparison to 0.575 from the Baseline classifier. Without the Plain Text Filter component as a part of the Text Processing module, the F-Score of the HMM Classifier was reduced to 0.378 on average, while absence of the HTML Filter component was found to have no impact. Reducing the Drug names dictionary size by half, on average reduced the F-Score of the HMM Classifier to 0.359, while a similar reduction to the side-effects dictionary yielded an F-Score of 0.651 on average. Adverse side-effects mined from http://www.medications.com and http://www.steadyhealth.com were found to match the Adverse Drug Reactions on the Drug Package Labels of several drugs. In addition, some novel adverse side-effects, which can be potential Adverse Drug Reactions, were also identified. The results from the HMM based Text Miner are encouraging to pursue further enhancements to this approach. The mined novel side-effects can act as early indicators for health authorities to help focus their efforts in post-marketing drug surveillance.

[Adverse ocular effects of vaccinations].

PubMed

Ness, T; Hengel, H

2016-07-01

Vaccinations are very effective measures for prevention of infections but are also associated with a long list of possible side effects. Adverse ocular effects following vaccination have been rarely reported or considered to be related to vaccinations. Conjunctivitis is a frequent sequel of various vaccinations. Oculorespiratory syndrome and serum sickness syndrome are considered to be related to influenza vaccinations. The risk of reactivation or initiation of autoimmune diseases (e. g. uveitis) cannot be excluded but has not yet been proven. Overall the benefit of vaccination outweighs the possible but very low risk of ocular side effects.

These are based on controlled observations with quantitative data and significant reports of results obtained in medical practice. In a summarizing section, the drugs are compared with respect to effectiveness, side-effects and addiction liability. Morphine-like drugs of natural and synthetic origin now cover a wide range of potency (analgesic, antitussive), not necessarily paralleled by incidence of side-effects or addiction liability.

Due to the highly localized exposure from mobile phones, the preferred side of the head during their use is important information when investigating a possible link with brain tumour risk, but at the same time, error and bias hamper the assessment of this information in case-control studies. Current studies provide evidence of reporting bias insofar as cases appear to over-report the side of the head where the tumour occurred as the one that they preferred in the past when using mobile phones. More refined methods of analysis among only cases or prospective studies with an assessment of the laterality of mobile phone use before the diagnosis of disease are needed to evaluate whether associations seen in some studies are entirely due to reporting bias or a mixture of reporting bias and a causal effect.

Long-pulsed Nd:YAG laser vs. intense pulsed light for hair removal in dark skin: a randomized controlled trial.

Although several lasers meet the wavelength criteria for selective follicular destruction, the treatment of darker skin phototypes is particularly challenging because absorption of laser energy by the targeted hairs is compromised by an increased concentration of epidermal melanin. To compare satisfaction level, safety and effectiveness of a long-pulsed Nd:YAG laser and intense pulsed light (IPL) in axillary hair reduction in subjects with dark skin. The study design was a within-patient, right-left, assessor-blinded, comparison of long-pulsed Nd:YAG laser and IPL. Fifty women (skin phototypes IV-VI) volunteered for removal of axillary hair. Five sessions at 4- to 6-week intervals were performed. Hair counts at both sides were compared at baseline and 6months after the last session. Final overall evaluations were performed by subjects and clinician at the end of the study. Satisfaction was scored for both devices. Thirty-nine women completed the study. At 6months, the decrease in hair counts on the laser side (79·4%, P<0·001 vs. pretreatment) was significantly (P<0·01) greater than that on the IPL side (54·4%, P<0·01 vs. pretreatment). Only temporary adverse effects were reported at both sides. Higher pain scores and more inflammation were reported with Nd:YAG laser; however, it was preferred by 29 volunteers (74%). Volunteers reported higher satisfaction score with Nd:YAG laser (P<0·01). Dark skin can be treated by both systems safely and effectively; however, long-pulsed (1064 nm) Nd:YAG laser is more effective as reported by both subjects and clinician. © 2011 The Authors.

Targeted therapies (TTs), notably trastuzumab, have improved outcomes for breast cancer characterised by overexpression of human epidermal growth factor receptors including HER2. Compared with chemotherapy treatments, TTs are more specific in their targets and are delivered over longer periods of time, thus presenting different side-effect profiles. The objective of this paper is to systematically review and describe the side effects associated with TTs used in the adjuvant and metastatic settings for HER2+ breast cancer. The MEDLINE, EMBASE, CINAHL, Web of Science and Cochrane Library databases were searched from January 2007 to March 2015 to identify clinical trials and prospective studies reporting toxicities associated with TTs (mainly trastuzumab and lapatinib) used without other therapies in the treatment of HER2-positive breast cancer. Two independent reviewers selected papers based on their titles and abstracts. All papers selected by either reviewer were included. A third reviewer extracted and tabulated the relevant data using a data extraction form. We identified 5478 papers, of which 299 were reviewed and 18 trials identified involving 6980 patients. A total of 66 side effects were identified, including 46 "patient-based" symptoms and 20 "medically defined" outcomes. Side effects were more common for patients treated with therapies other than trastuzumab or with dual-HER2 regimens and for patients with metastatic disease. Diarrhoea and skin rash were the most prevalent symptoms, experienced by 29 % and 22 % of patients overall, respectively. There were 119 (2 %) cardiac events reported, and these were not exclusive to trastuzumab-treated patients. The majority of side effects (n = 52) were experienced by 1 % or less of patients and were predominantly of grade 1/2 toxicity. This systematic review provides a detailed analysis of side effects of HER2+ therapies in a large number of patients included in trials, enabling an accurate estimate of prevalence and a complete understanding of the patients' experience. This will help clinicians and patients in treatment planning.

Background: Musculoskeletal injuries to the extremities are a primary concern for the United States (US) military. One possible injury risk factor in this population is side-to-side strength imbalance. Purpose: To examine the odds of reporting a previous shoulder injury in US Marine Corps Ground Combat Element Integrated Task Force volunteers based on side-to-side strength differences in isokinetic shoulder strength. Study Design: Cohort study; Level of evidence, 3. Methods: Male (n = 219) and female (n = 91) Marines were included in this analysis. Peak torque values from 5 shoulder internal/external rotation repetitions were averaged and normalized to body weight. The difference in side-to-side strength measurements was calculated as the absolute value of the limb difference divided by the mean peak torque of the dominant limb. Participants were placed into groups based on the magnitude of these differences: <10%, 10% to 20%, and >20%. Odds ratios (ORs) and 95% CIs were calculated. Results: When separated by sex, 13.2% of men reported an injury, while 5.5% of women reported an injury. Female Marines with >20% internal rotation side-to-side strength differences demonstrated increased odds of reporting a previous shoulder injury compared with female Marines with <10% strength differences (OR, 15.4; 95% CI, 1.4-167.2; P = .03 ) and female Marines with 10% to 20% strength differences (OR, 13.9; 95% CI, 1.3-151.2; P = .04). No significant ORs were demonstrated in male Marines. Conclusion: Marines with larger magnitude internal rotation strength differences demonstrated increased odds of reporting a previous shoulder injury compared with those with lesser magnitude differences. Additionally, female sex appears to drastically affect the increased odds of reporting shoulder injuries (OR, 13.9-15.4) with larger magnitude differences (ie, >20%) compared with those with lesser magnitude differences (ie, <10% and 10%-20%). The retrospective cohort design of this study cannot delineate cause and effect but establishes a relationship between female Marines and greater odds of larger magnitude strength differences after returning from an injury.

Many migraine sufferers use daily prophylactic therapy to reduce the frequency of their headache attacks. The Food and Drug Administration has approved several different medications for migraine prophylaxis, but it is not clear whether sufferers perceive these treatments to provide clinically significant benefits given their side effect profiles. Three hundred headache sufferers were recruited from the community and local headache clinics using print and television advertising. Participants reported experiencing problematic headache attacks with a median (IQR) frequency of 7.0 (4-13) headache days per month. These sufferers participated in a cross-sectional, single-site, study that used a specially designed computer assessment task. Participants were instructed on the probability of experiencing the 3 most commonly experienced side effects for several blinded medication profiles: divalproex sodium, venlafaxine, gabapentin, propranolol, and topiramate. After learning the likelihood of experiencing side effect profiles of each medication, participants were asked whether they would be willing to take the medication for a given headache reduction level, which ranged from 0 to 7 days per month. The side effect profile for divalproex sodium was associated with the smallest willingness to take, with gabapentin, propranolol, and topiramate perceived to be much more agreeable. However, <60% of participants reported willingness to take any of these medications even if they provided a 50% reduction in headache frequency. Several general predictors of willingness to take were observed including high headache-related disability, depressive symptoms, and pain medication concerns including fear of tolerance. These findings suggest that if properly informed of the side effect profiles of these medications, many patients might opt for other treatments.

Fatigue is the most prevalent and disabling symptom in cancer patients. Yet, scientific literature on this topic is scarce and reports disparate results. This study systematically reviews how fatigue is assessed in patients with low-grade glioma and evaluates its prevalence in LGG patients. A systematic literature search was performed in PubMed, Embase and PsychINFO for articles reporting on fatigue in patients with LGG. Two reviewers independently extracted data from selected articles. Inclusion criteria were: (1) patients with suspected or confirmed LGG; (2) fatigue was assessed as primary or secondary outcome measure; (3) age≥ 18 years; (4) full-length article written in English or Dutch. In total, 19 articles were selected, including 971 patients. Seven self-assessment instruments were identified. Prevalence rates ranged from 39 to 77%. Fatigue was found to be a common side effect of treatment. The prevalence rates ranged from 20 to 76% when fatigue was reported as a mild or moderate side effect and fatigue was prevalent in 4% when reported as a severe side effect. Fatigue is a common problem in LGG patients that warrants more therapeutic and scientific attention. Gaining deeper insight in the underlying mechanisms of fatigue is essential in targeting therapy to individual patients.

Cholestatic hepatitis as a possible new side-effect of oxycodone: a case report

PubMed Central

Ho, Vincent; Stewart, Maxwell; Boyd, Peter

2008-01-01

Introduction Oxycodone is a widely-used semisynthetic opioid analgesic that has been used for over eighty years. Oxycodone is known to cause side effects such as nausea, pruritus, dizziness, constipation and somnolence. As far as we are aware cholestatic hepatitis as a result of oxycodone use has not been reported so far in the world literature. Case presentation A 34-year-old male presented with cholestatic jaundice and severe pruritus after receiving oxycodone for analgesia post-T11 vertebrectomy. Extensive laboratory investigations and imaging studies did not reveal any other obvious cause for his jaundice and a liver biopsy confirmed canalicular cholestatis suggestive of drug-induced hepatotoxicity. The patient's symptoms and transaminases normalised on withdrawal of oxycodone confirming that oxycodone was the probable cause of the patient's hepatotoxicity. Conclusion We conclude that cholestatic hepatitis is possibly a rare side effect of oxycodone use. Physicians should be aware of the possibility of this potentially serious picture of drug-induced hepatotoxicity. PMID:18452597

Background. Cancer patients using cannabis report better influence from the plant extract than from synthetic products. However, almost all the research conducted to date has been performed with synthetic products. We followed patients with a medicinal cannabis license to evaluate the advantages and side effects of using cannabis by cancer patients. Methods. The study included two interviews based on questionnaires regarding symptoms and side effects, the first held on the day the license was issued and the second 6–8 weeks later. Cancer symptoms and cannabis side effects were documented on scales from 0 to 4 following the CTCAE. The distress thermometer was used also. Results. Of the 211 patients who had a first interview, only 131 had the second interview, 25 of whom stopped treatment after less than a week. All cancer or anticancer treatment-related symptoms showed significant improvement (P < 0.001). No significant side effects except for memory lessening in patients with prolonged cannabis use (P = 0.002) were noted. Conclusion. The positive effects of cannabis on various cancer-related symptoms are tempered by reliance on self-reporting for many of the variables. Although studies with a control group are missing, the improvement in symptoms should push the use of cannabis in palliative treatment of oncology patients. PMID:23956774

Colonoscopy is widely regarded to be the gold standard for colorectal cancer (CRC) detection. Recent studies, however, suggest that the effectiveness of colonoscopy is mostly confined to tumors on the left side of the colon (descending, sigmoid, rectum), and that the technology has poor tumor detection for right-sided (cecum, ascending, transverse) lesions. A minimally invasive test that can detect both left-sided and right-sided lesions could increase the effectiveness of screening colonoscopy by revealing the potential presence of neoplasms in the right-sided "blind spot". We previously reported on a seven-gene, blood-based biomarker panel that effectively stratifies a patient's risk of having CRC. For the current study, we assessed the effectiveness of the seven-gene panel for the detection of left- and right-sided CRC lesions. Results were evaluated for 314 patients with CRC (left-sided: TNM I, 65; TNM II, 57; TNM III, 60; TNM IV, 17; unknown, 9. right-sided: TNM I, 28; TNM II, 29; TNM III, 38; TNM IV, 12; unknown, 1 and including two samples with both left and right lesions) and 328 control samples. Blood samples were obtained prior to clinical staging and therapy. Most CRC subjects had localized disease (stages I and II, 58%); regional (stage III) and systemic (stage IV) disease represented 32% and 9%, respectively, of the study population. The panel detected left-sided (74%, 154/208) and right-sided (85%, 92/108) lesions with an overall sensitivity of 78% (215/316) at a specificity of 66% (215/328). Treatable cancer (stages I to III) was detected with left-sided lesion sensitivity of 76% (138/182) and right-sided sensitivity of 84% (80/95). This seven-gene biomarker panel detected right-sided CRC lesions across all cancer stages with a sensitivity that is at least equal to that for left-sided lesions. This study supports the use of this panel as the basis for a patient-friendly, blood-based test that can be easily incorporated into a routine physical examination in advance of colonoscopy to provide a convenient companion diagnostic and a pre-screening alert, ultimately leading to enhanced CRC screening effectiveness.

Leakage and field emission in side-gate graphene field effect transistors

We fabricate planar graphene field-effect transistors with self-aligned side-gate at 100 nm from the 500 nm wide graphene conductive channel, using a single lithographic step. We demonstrate side-gating below 1 V with conductance modulation of 35% and transconductance up to 0.5 mS/mm at 10 mV drain bias. We measure the planar leakage along the SiO{sub 2}/vacuum gate dielectric over a wide voltage range, reporting rapidly growing current above 15 V. We unveil the microscopic mechanisms driving the leakage, as Frenkel-Poole transport through SiO{sub 2} up to the activation of Fowler-Nordheim tunneling in vacuum, which becomes dominant at higher voltages. We report a field-emission current densitymore » as high as 1 μA/μm between graphene flakes. These findings are important for the miniaturization of atomically thin devices.« less

Integrative relational machine-learning for understanding drug side-effect profiles

PubMed Central

2013-01-01

Background Drug side effects represent a common reason for stopping drug development during clinical trials. Improving our ability to understand drug side effects is necessary to reduce attrition rates during drug development as well as the risk of discovering novel side effects in available drugs. Today, most investigations deal with isolated side effects and overlook possible redundancy and their frequent co-occurrence. Results In this work, drug annotations are collected from SIDER and DrugBank databases. Terms describing individual side effects reported in SIDER are clustered with a semantic similarity measure into term clusters (TCs). Maximal frequent itemsets are extracted from the resulting drug x TC binary table, leading to the identification of what we call side-effect profiles (SEPs). A SEP is defined as the longest combination of TCs which are shared by a significant number of drugs. Frequent SEPs are explored on the basis of integrated drug and target descriptors using two machine learning methods: decision-trees and inductive-logic programming. Although both methods yield explicit models, inductive-logic programming method performs relational learning and is able to exploit not only drug properties but also background knowledge. Learning efficiency is evaluated by cross-validation and direct testing with new molecules. Comparison of the two machine-learning methods shows that the inductive-logic-programming method displays a greater sensitivity than decision trees and successfully exploit background knowledge such as functional annotations and pathways of drug targets, thereby producing rich and expressive rules. All models and theories are available on a dedicated web site. Conclusions Side effect profiles covering significant number of drugs have been extracted from a drug ×side-effect association table. Integration of background knowledge concerning both chemical and biological spaces has been combined with a relational learning method for discovering rules which explicitly characterize drug-SEP associations. These rules are successfully used for predicting SEPs associated with new drugs. PMID:23802887

To examine baseline psychological functioning and antiepileptic drug (AED) behavioral side effects in new onset epilepsy and determine, by age, whether baseline psychological functioning predicts AED behavioral side effects 1 month following AED initiation. A retrospective chart review was conducted between July 2011 and December 2014 that included youths with new onset epilepsy. As part of routine interdisciplinary care, caregivers completed the Behavior Assessment System for Children, 2nd Edition: Parent Rating Scale to report on baseline psychological functioning at the diagnostic visit and the Pediatric Epilepsy Side Effects Questionnaire to identify AED behavioral side effects at the 1-month follow-up clinic visit following AED initiation. Children (age = 2-11 years) and adolescents (age = 12-18 years) were examined separately. A total of 380 youths with new onset epilepsy (M age  = 8.9 ± 4.3 years; 83.4% Caucasian; 34.8% focal epilepsy, 41.1% generalized epilepsy, 23.7% unclassified epilepsy) were included. Seventy percent of youths had at-risk or clinically elevated baseline psychological symptoms. Children had significantly greater AED behavioral side effects (M = 25.08 ± 26.36) compared to adolescents (M = 12.36 ± 17.73), regardless of AED. Valproic acid demonstrated significantly greater behavioral side effects compared to all other AEDs, with the exception of levetiracetam. Higher hyperactivity/impulsivity at baseline significantly predicted higher AED behavioral side effects 1 month after AED initiation in both age groups. Younger children seem to be more prone to experience behavioral side effects, and these are likely to be higher if youths with epilepsy have baseline hyperactivity/impulsivity. Baseline psychological screening, specifically hyperactivity, can be used as a precision medicine tool for AED selection. Wiley Periodicals, Inc. © 2017 International League Against Epilepsy.

The German fibromyalgia consumer reports – a cross-sectional survey

PubMed Central

2012-01-01

Background Consumer surveys provide information on effectiveness and side effects of medical interventions in routine clinical care. A report of fibromyalgia syndrome (FMS) consumers has not been carried out in Europe. Methods The study was carried out from November 2010 to April 2011. Participants diagnosed with FMS rated the effectiveness and side effects of pharmacological and non-pharmacological FMS interventions on a 0 to 10 scale, with 10 being most efficacious (harmful). The questionnaire was distributed by the German League for people with Arthritis and Rheumatism and the German Fibromyalgia Association to their members and to all consecutive FMS patients of nine clinical centers of different levels of care. Results 1661 questionnaires (95% women, mean age 54 years, mean duration since FMS diagnosis 6.8 years) were analysed. The most frequently used therapies were self-management strategies, prescription pain medication and aerobic exercise. The highest average effectiveness was attributed to whole body and local warmth therapies, thermal bathes, FMS education and resting. The highest average side effects were attributed to strong opioids, local cold therapy, gamma-amino-butyric acid analogues (pregabalin and gabapentin), tramadol and opioid transdermal systems. Conclusion The German fibromyalgia consumer reports highlight the importance of non-pharmcological therapies in the long-term management of FMS, and challenges the strong recommendations for drug therapies given by FMS-guidelines.

Adherence to attention deficit hyperactivity disorder (ADHD) treatment is important because, when untreated, it may have serious consequences with lifelong effects. In the case of adolescents on long-term medicine prescription, more knowledge is needed regarding adherence and factors influencing adherence, which was the purpose of this study. Adolescents (n = 101) on ADHD medication ≥6 months were administrated questionnaires at a monitoring appointment: Medication Adherence Report Scale (MARS), beliefs about medicines (BMQ) and the Brief Illness Perception Questionnaire (B-IPQ). Adherence was high, the mean value was 88% of the maximum MARS score, and correlated positively with the "BMQ-necessity-concerns differential" but negatively with "BMQ-concerns" and "BMQ-side effects". Adolescents with more belief in the necessity of the medication, less concerns and less experience of side effects tended to be more adherent to medication prescription ("intentional non-adherence"), while "unintentional non-adherence" (forgetfulness) was associated with how much they perceived that their ADHD affected their lives. In a multiple regression model, the variance of MARS total (R 2  = 0.21) and "intentional non-adherence" (R 2  = 0.24) was explained by the "BMQ-necessity-concern differential" and "BMQ-experienced side effects". The variance of "unintentional non-adherence" (R 2  = 0.12) was explained by the "BMQ-necessity-concern differential" and "B-IPQ-consequences of ADHD". In conclusion, adolescents on long-term medication reported good adherence, mainly influenced by more beliefs in the necessity versus concerns of the medications, less experienced side effects and more perceived consequences of ADHD. BMQ could be useful to identify risks of low adherence, which should be counteracted by partially gender-specific interventions.

The first report of gynandromorphy in termites (Isoptera; Kalotermitidae; Neotermes koshunensis).

This is the first report of gynandromorphy in Isoptera. An Asian dry-wood termite, Neotermes koshunensis (Shiraki) [Kalotermitidae], possessing both male and female phenotypic characteristics, was found on Okinawa Island, Japan. This deformed individual showed morphological and anatomical hermaphroditism in the abdomen. The right side of the seventh sternite was the female form and contained an ovary, while the left side was the male form and contained a testis. Genotypic analysis revealed that this individual was a genotypic bilateral chimera. These results suggested that the termite was a bilateral gynandromorph with a male left side and a female right side. As reported previously in other insects, double fertilization (by two sperms, one with an X and one with a Y chromosome) of a binucleate egg is the most likely mechanism that generated this genotypic bilateral chimera. N. koshunensis has the ability to reproduce through parthenogenesis, in which the secondary polar body is likely to be used for nuclear phase recovery. If the second polar body in this mechanism has high fertility and healthy embryogenic potential, like an egg nucleus, some of gynandromorphs might be produced by a side effect of parthenogenetic ability.

Increased cognitive problem reporting after information about chemotherapy-induced cognitive decline: The moderating role of stigma consciousness.

PubMed

Jacobs, W; Das, E; Schagen, S B

2017-01-01

Information about treatment side effects can increase their occurrence; breast cancer (BC) patients showed increased cognitive problem reporting (CPR) and decreased memory performance after information about cognitive side effects. The current study extends previous research on adverse information effects (AIE) by investigating (a) risk factors, (b) underlying mechanisms and (c) an intervention to reduce AIE. In an online experiment, 175 female BC patients were randomly assigned to one of three conditions. In the two experimental groups, patients were informed about the possible occurrence of cognitive problems after chemotherapy with (intervention group) or without (experimental group) reassuring information that 'there are still patients who score well on memory tests'. In the control group, no reference to chemotherapy-related cognitive problems was made. Main dependent measure was CPR. Four moderating and five mediating processes were examined. CPR increased with higher levels of stigma consciousness in the two experimental groups, but not in the no-information control group. Merely informing patients about cognitive side effects may increase their occurrence, especially among individuals vulnerable to patient stereotypes. Adding reassuring information is not sufficient to reduce AIE.

Field data on side airbag deployments in lateral crashes and head injuries have largely remained anecdotal. Consequently, the purpose of this research was to report head injuries in lateral motor vehicle impacts. Data from the National Automotive Sampling System files were extracted from side impacts associated with side airbag deployments. Matched pairs with similar vehicle characteristics but without side airbags were also extracted. All data were limited to the United States Federal Motor vehicle Safety Standards FMVSS 214 compliant vehicles so that the information may be more effectively used in the future. In this study, some fundamental analyses are presented regarding occupant- and vehicle-related parameters. PMID:16179147

The aim of the study was to evaluate safety and feasibility of dobutamine cardiovascular magnetic resonance (CMR) in patients with proven or suspected coronary artery disease. Dobutamine CMR was evaluated retrospectively in 400 consecutive patients with suspicion of myocardial ischemia. Dobutamine was infused using an incremental protocol up to 40 microg/kg body weight per minute. All anti-anginal medication was stopped 4 days before the CMR study and infusion time of dobutamine was 6 min per stage. Hemodynamic data, CMR findings and side effects were reported. Patients with contraindications to CMR (metallic implants and claustrophobia) were excluded from analysis. Dobutamine CMR was successfully performed in 355 (89%) patients. Forty-five (11%) patients could not be investigated adequately because of non-cardiac side effects in 29 (7%) and cardiac side effects in 16 (4%) patients. Hypotension (1.5%) and arrhythmias (1%) were the most frequent cardiac side effects. One patient developed a severe complication (ventricular fibrillation) at the end of the study. There were no myocardial infarctions or fatal complications of the stress test. The most frequent non-cardiac side effects were nausea, vomiting and claustrophobia. Age >70 years, prior myocardial infarction and rest wall motion abnormalities showed no significant differences with side effects (P>0.05). Dobutamine CMR is safe and feasible in patients with suspicion of myocardial ischemia. Copyright 2004 Springer-Verlag

With improved prognosis due to advances in the diagnosis and therapy of breast cancer, physicians and therapists now focus on aspects such as quality of life and the management of side effects from breast cancer treatment. Therapy- and disease-related side effects often reduce the patientʼs quality of life and can place a further burden on patients, with non-compliance or discontinuation of therapy a potential consequence. Study data have shown that therapy- and disease-related side effects can be reduced using the methods of integrative medicine. Reported benefits include improving patientsʼ wellbeing and quality of life, reducing stress, and improving patientsʼ mood, sleeping patterns and capacity to cope with disease. Examining the impact of integrative medicine on the side effects of cancer treatment would be beyond the scope of this review. This article therefore looks at short-term side effects of cancer treatment which are usually temporary and occur during or after local and systemic therapy. The focus is on mind-body medicine, acupuncture and classic naturopathic treatments developed by Sebastian Kneipp as complementary therapies. The latter includes hydrotherapy, phytotherapy, nutritional therapy, exercise therapy and a balanced lifestyle. PMID:26257404

Introduction People with homonymous visual field defects (HVFD) often report difficulty detecting obstacles in the periphery on their blind side in time when moving around. Recently, a randomized controlled trial showed that the InSight-Hemianopia Compensatory Scanning Training (IH-CST) specifically improved detection of peripheral stimuli and avoiding obstacles when moving around, especially in dual task situations. Method The within-group training effects of the previously reported IH-CST are examined in an extended patient group. Performance of patients with HVFD on a pre-assessment, post-assessment and follow-up assessment and performance of a healthy control group are compared. Furthermore, it is examined whether training effects can be predicted by demographic characteristics, variables related to the visual disorder, and neuropsychological test results. Results Performance on both subjective and objective measures of mobility-related scanning was improved after training, while no evidence was found for improvement in visual functions (including visual fields), reading, visual search and dot counting. Self-reported improvement did not correlate with improvement in objective mobility performance. According to the participants, the positive effects were still present six to ten months after training. No demographic characteristics, variables related to the visual disorder, and neuropsychological test results were found to predict the size of training effect, although some inconclusive evidence was found for more improvement in patients with left-sided HVFD than in patients with right-sided HFVD. Conclusion Further support was found for a positive effect of IH-CST on detection of visual stimuli during mobility-related activities specifically. Based on the reports given by patients, these effects appear to be long-term effects. However, no conclusions can be drawn on the objective long-term training effects. PMID:27935973

FX-87 performance measurements: data-flow implementation. Technical report

This report documents a series of experiments performed to explore the thesis that the FX-87 effect system permits a compiler to schedule imperative programs (i.e., programs that may contain side-effects) for execution on a parallel computer. The authors analyze how much the FX-87 static effect system can improve the execution times of five benchmark programs on a parallel graph interpreter. Three of their benchmark programs do not use side-effects (factorial, fibonacci, and polynomial division) and thus did not have any effect-induced constraints. Their FX-87 performance was comparable to their performance in a purely functional language. Two of the benchmark programsmore » use side effects (DNA sequence matching and Scheme interpretation) and the compiler was able to use effect information to reduce their execution times by factors of 1.7 to 5.4 when compared with sequential execution times. These results support the thesis that a static effect system is a powerful tool for compilation to multiprocessor computers. However, the graph interpreter we used was based on unrealistic assumptions, and thus our results may not accurately reflect the performance of a practical FX-87 implementation. The results also suggest that conventional loop analysis would complement the FX-87 effect system« less

The high frequency of treatment-related side effects for men with localized prostate cancer creates uncertainty for treatment outcomes. This study assessed the comparative effectiveness of treatment-related side effects associated with conservative management and cryotherapy in patients with localized prostate cancer. A retrospective longitudinal cohort study was conducted, using the linked data of the Surveillance, Epidemiology, and End Results and Medicare, which included patients diagnosed from 2000 through year 2013, and their Medicare claims information from 2000 through 2014. To compare the differences in baseline characteristics and treatment-related side effects between the study cohorts, χ 2 tests were conducted. Multivariate logistic regression was used to assess the association between treatment selection and side effects. There were 7,998 and 3,051 patients in the conservative management and cryotherapy cohort, respectively. The likelihood of erectile dysfunction, lower urinary tract obstruction, urinary fistula, urinary incontinence, and hydronephrosis was reported to be significantly lower (53%, 35%, 69%, 65%, and 36%, respectively) in the conservative management cohort. Conservative management had a lower likelihood of treatment-related side effects compared to cryotherapy. However, further research is needed to compare other significant long-term outcomes such as costs associated with these treatment choices and quality of life.

Hepatitis C virus (HCV) antiviral therapy entails a long treatment course, as well as significant side effects that can lead to medication non-adherence and premature termination of treatment. Few large studies have comprehensively examined patient perspectives on the treatment experience, particularly the social and personal effects. We sought to understand how a diverse group of patients' lives were affected during HCV treatment, and to obtain suggestions about how to better support patients during treatment. On average, 13 months after therapy we interviewed by telephone a consecutive sample of 200 patients treated for hepatitis C with ribavirin and pegylated interferon in a comprehensive, integrated health plan in the years 2008-2010. Mixed (quantitative and qualitative) survey methods were used. The response rate was 68.9 %. Mean age at treatment was 51 years; 63.0 % were men; and Black, Hispanic, Asian, and White non-Hispanic racial/ethnic groups were similarly represented. Patients whose treatment was managed by nurses or clinical pharmacists (vs. physicians) were more likely to report their providers as being part of their support system (83.5 % vs. 58.9 %; p < 0.001). Most patients reported flu-like symptoms (93.5 %) and psychiatric problems (84.5 %), and 42.5 % reported side effects lasted up to 6 months after treatment. Black patients reported discontinuing treatment prematurely due to side effects more often than non-Blacks (29.4 % vs. 12.1 %; p < 0.001). Physical side effects (69.5 % of patients), psychiatric issues (43.5 %), and employment (27.4 %) were ranked among the three most difficult challenges. Patients desired help in anticipating and arranging work modifications during treatment. Most patients rated peer support, nutritional guidance, and weekly provider contact by telephone as potentially helpful resources for future patients undergoing HCV treatment. Patient perspectives can help formulate and refine HCV treatment support programs. Effective support programs for diverse populations are crucial as the complexities and costs of HCV treatment increase. The call for greater support from peers, providers, and employers demands new systems such as patient-centered care teams.

Adverse effects of drugs are poorly reported in the literature . The aim of this study was to examine the frequency of the adverse events of antiepileptic drugs (AEDs), in particular carbamazepine (CBZ) and oxcarbazepine (OXC) in patients with neuralgiform pain using the psychometrically tested Liverpool Adverse Events Profile (AEP) and provide clinicians with guidance as to when to change management. The study was conducted as a clinical prospective observational exploratory survey of 161 patients with idiopathic trigeminal neuralgia and its variants of whom 79 were on montherapy who attended a specialist clinic in a London teaching hospital over a period of 2 years. At each consultation they completed the AEP questionnaire which provides scores of 19-76 with toxic levels being considered as scores >45. The most common significant side effects were: tiredness 31.3 %, sleepiness 18.2 %, memory problems 22.7 %, disturbed sleep 14.1 %, difficulty concentrating and unsteadiness 11.6 %. Females reported significantly more side effects than males. Potential toxic dose for females is approximately 1200 mg of OXC and 800 mg of CBZ and1800mg of OXC and 1200 mg of CBZ for males. CBZ and OXC are associated with cognitive impairment. Pharmacokinetic and pharmacodynamic differences are likely to be the reason for gender differences in reporting side effects. Potentially, females need to be prescribed lower dosages in view of their tendency to reach toxic levels at lower dosages. Side effects associated with AED could be a major reason for changing drugs or to consider a referral for surgical management.

The aim of this study was to investigate the efficacy and side effects of botulinum toxin (BTX) in the treatment of hemifacial spasm (HFS). We also focused on the divergence between different injection techniques and commercial forms. We retrospectively evaluated 470 sessions of BTX injections administered to 68 patients with HFS. The initial time of improvement, duration and degree of improvement, and frequency and duration of adverse effects were analysed. Pretarsal and preseptal injections and Botox (Allergan, Irvine, CA, USA) and Dysport (Ipsen Biopharmaceuticals, Paris, France) brands were compared in terms of efficacy and side effects, accompanied by a review of papers which reported BTX treatment of HFS. An average of 34.5 units was used per patient. The first improvement was felt after 8 days and lasted for 14.8 weeks. Patients experienced a 73.7% improvement. In 79.7% of injections, no adverse effect was reported, in 4.9% erythema, ecchymosis, and swelling in the injection area, in 3.6% facial asymmetry, in 3.4% ptosis, in 3.2% diplopia, and in 2.3% difficulty of eye closure was detected. Patients reported 75% improvement on average after 314 sessions of pretarsal injections and 72.7% improvement after 156 sessions of preseptal injections (p=0.001). The efficacy and side effects of Botox and Dysport were similar. BTX is an effective and safe treatment option for HFS. No difference was determined between Botox and Dysport, and pretarsal injection is better than preseptal injection regarding the reported degree of improvement. Copyright © 2015 Elsevier Ltd.

2018-01-01

ABSTRACT Angioedema has recently been reported as a side effect associated with the antipsychotic risperidone. We report a case of dystonia with concurrent angioedema due to risperidone. A 40-year-old male with a history of schizophrenia was started on 3 mg of risperidone BID and developed perioral and periorbital edema along with increased muscle rigidity and hand tremor within 24 h of initial administration. His symptoms abated after cessation of risperidone and intravenous administration of corticosteroids and antihistamine. This case study adds to the current literature, which has already established angioedema as a dose-dependent side effect of risperidone. Moreover, this case study aims to increase awareness about the potential for the simultaneous occurrence of angioedema and extrapyramidal symptoms, and promotes vigilance among prescribers so that the life-threatening consequences of such effects can be avoided.

Pegylated-interferon-α/ribavirin (PEG-IFN/RBV) treatment can cure hepatitis C virus (HCV) infection but has frequent neuropsychiatric side-effects. Patients with pre-existing psychiatric illness may not be offered therapy. We established prevalence of self-reported psychiatric comorbidity among HCV-infected patients in a hospital-liver clinic, and determined the impact of such diagnoses on uptake and tolerance to PEG-IFN/RBV. All HCV cases referred for assessment in Australian Capital Territory/surrounding regions April 2004-March 2012 were entered into a clinical database. We conducted univariate and multivariate analyses of variables correlating with uptake of antiviral therapy and frequency of treatment-related side-effects. Of 773 referred patients, 235 (30%) described pre-existing psychiatric illness. Among these, 26% received antiviral therapy, compared with 30% of 538 without psychiatric comorbidity. History of depression (usually validated by liaison psychiatry) was associated with higher incidence of treatment-related neuropsychiatric side-effects (odds ratio 2.79 [1.35-5.70], P < 0.05) but did not affect treatment outcome. Twenty-seven patients reported schizophrenia: three (11%) received antiviral therapy, compared with 30% admitting depression and 20% with bipolar affective disorder (all assessed by psychiatrist). In most schizophrenia cases, the reason for not offering antiviral treatment was psychological illness, yet none of five treated (these three plus two others in a psychiatric rehabilitation facility) experienced worsening psychiatric symptoms. A history of depression is common with hepatitis C but does not affect initiation of antiviral treatment, despite substantially increased risk of psychiatric side-effects. In contrast, pre-existing schizophrenia appears to influence treatment decisions, despite little evidence that PEG-IFN/RBV exacerbates the psychiatric condition, and well-supervised antiviral therapy can have good outcomes.

Pancreatic adenocarcinoma and renal cell carcinoma are relatively frequent cancers that have been rarely reported as synchronous primary malignancies. When present simultaneously, they pose a therapeutic challenge given the many available targeted agents with reported efficacy in renal cell cancer and limited options for metastatic pancreatic cancer. We report the case of a 43-year-old Caucasian gentleman diagnosed simultaneously with metastatic pancreatic adenocarcinoma and localized renal cell carcinoma treated with combination chemotherapy, consisting of gemcitabine and sunitinib. Patient had a radiographic response and prolonged progression free survival of twenty six weeks; side effects were manageable and included grade 3 neutropenia and grade 2 hypertension. This encouraging response, safety profile and progression free survival response suggest that we should further examine this and other such regimens to improve clinical outcomes for maximum efficacy with minimal side-effects.

Doxorubicin is one of the most effective chemotherapeutic agents used in the treatment of malignancies. Cardiotoxicity is the most important dose-limiting toxicity of doxorubicin. Although cardiomyopathy is the most well known side effect of doxorubicin, it usually occurs many years after the treatment and relates to cumulative doxorubicin dosage. Another form of doxorubicin cardiotoxicity is arrhythmia which may occur at any time and after any dosage. However, doxorubicin-induced arrhythmia is rarely a life-threatening side effect. In this report, we present a case in which there were doxorubicin-induced life-threatening arrhythmias.

An audit of the use of intra-septal local anaesthesia in a dental practice in the South of England.

Doman, Stephen M

2011-04-01

The aim of this audit was to evaluate the efficacy, when used by the author, of the intra-septal local anaesthetic technique for cavity preparation in mandibular molar and premolar teeth. One hundred and thirteen consecutive patients who required local anaesthesia (LA) for cavity preparation in lower molar and premolar teeth in a general dental practice took part in the audit sample. Articaine 4%, with 1:100,000 adrenaline (epinephrine), was administered using the intra-septal technique. Visual analogue scales (VAS) were used to record pain experienced on injection and the quality of anaesthesia obtained. Any side-effects reported were recorded. The standards set were that at least 70% should find the administration of the LA pain-free and that at least 80% should experience no pain during cavity preparation. Sixty-nine (62%) patients reported the injection technique to be completely pain-free and a further 23 (20%) reported very minor pain on injection. Eighty (71%) patients reported pain-free treatment and 18 (16%) experienced very minor pain during treatment. No side-effects were reported. Patients aged under 40 years and those who had cavities prepared in first premolar teeth appeared more likely to experience pain during cavity preparation. The intra-septal injection technique requires no specialist equipment, is easily administered, rapid in onset and provides a level of anaesthesia equivalent to that produced by an inferior dental nerve block and with fewer side-effects. The injection is relatively painless to administer.

Whereas the efficacy of the newer antiepileptic drugs (AEDs) is well established, there remain questions regarding their cognitive side effects. Therefore, we performed a comparative open randomized trial with TPM and TGB as add-on therapy, with particular consideration of cognition, mood, and health-related quality of life (HRQOL). Forty-one patients with refractory epilepsy were randomly assigned to one of the two treatment groups (TPM vs TGB) and received neuropsychological testing at baseline (T1), after titration (3 months, T2), and during the maintenance phase (another 3 months, T3). Tests included measures of intelligence, attention, working memory, episodic memory, language, and self-report questionnaires regarding mood and HRQOL. Twenty patients (8 TPM, 12 TGB) discontinued the trial for different reasons (no group difference). Seizure outcome (intention-to-treat analysis) was comparably good in both groups (8.1% seizure free, 29.7% seizure reduction>50%). From baseline to after the titration paired sample t tests revealed significant deterioration in verbal fluency, language comprehension, working memory, and visual block tapping under TPM and a deterioration in verbal memory (delayed free recall) in the TGB group. These functions remained stable in the maintenance phase. Self-report measures initially indicated concerns about AED side effects in both groups and concerns about worse cognitive functioning and depression under TPM. In the maintenance phase the TGB group reported feeling a lack of energy, whereas patients on TPM demonstrated improvement on all QOLIE scales on a descriptive level. This study demonstrates the comparable efficacy of TPM and TGB. Consistent with previous reports, TPM but not TGB appears to be associated with persistent negative cognitive side effects on frontal lobe-associated functions, the degree of which may be estimated by the fact that this effect was observed with a very small sample size. In contrast, in patients taking TPM, initially negatively affected HRQOL returns to baseline in the long run on a descriptive level. The latter finding may be interpreted in accordance with the observation that objective performance and subjective self-report under TPM can be dissociated.

Review about gabapentin misuse, interactions, contraindications and side effects

PubMed Central

Quintero, Gabriel C

2017-01-01

The current work is targeted to review the risks of gabapentin misuse, its potential interactions with other drugs, side effects and use contraindications. This review consists of a total of 99 biographical references (from the year 1983 to 2016). A publication search of PubMed was performed from January 1983 to December 2016. It included animal studies, clinical studies, case studies and reviews related to gabapentin misuse, potential interactions, side effects and use contraindications. The search terms were gabapentin, anticonvulsant and antiepileptic. In general, it seems that gabapentin has risks of being misused based on the increased level of prescriptions, related fatalities, recreational misuse and higher doses of self-administration. The main reasons for gabapentin misuse are as follows: getting high, alleviating opioid withdrawal symptoms and potentiating methadone effects. Some of the main substances that interact with gabapentin are morphine, caffeine, losartan, ethacrynic acid, phenytoin, mefloquine and magnesium oxide. Some of the side effects caused by gabapentin are teratogenicity, hypoventilation, respiratory failure and myopathy. Finally, reports in general contraindicate the use of gabapentin in conditions such as myasthenia gravis and myoclonus. PMID:28223849

Context: Polycystic ovary syndrome (PCOS) is common among women of childbearing age and the available pharmacological therapies have different side-effect profiles. Objective: We summarized the evidence about the side effects of oral contraceptive pills, metformin, and anti-androgens in women with PCOS. Data Source: Sources included Ovid Medline, OVID EMBASE, OVID Cochrane Library, Web of Science, Scopus, PsycInfo, and CINAHL from inception through April 2011. Study Selection: We included comparative observational studies enrolling women with PCOS who received the agents of choice for at least 6 months and reported adverse effects. Data Extraction: Using a standardized, piloted, and Web-based data extraction form and working in duplicate, we abstracted data from each study and performed meta-analysis when possible. Data Synthesis: We found 22 eligible studies of which 20 were randomized. No study reported severe side effects (eg, lactic acidosis, thromboembolic episodes, liver toxicity, cancer incidence, or pregnancy loss). Meta-analysis demonstrated no significant change in weight in oral contraceptive pills or flutamide users. Indirect evidence from populations without PCOS demonstrated no increased risk of lactic acidosis with metformin, only case reports of liver toxicity with flutamide (no comparative evidence), and increased relative risk difference of venous thromboembolism with oral contraceptive pills but very low absolute risk. Evidence on mortality, cardiovascular mortality, and cancer was inconclusive. Conclusions: Drugs commonly used to treat PCOS appear to be associated with very low risk of severe adverse effects although data are extrapolated from other populations. PMID:24092830

In order to determine the feasibility of utilizing novel rexinoids for chemotherapeutics and as potential treatments for neurological conditions, we undertook an assessment of the side effect profile of select rexinoid X receptor (RXR) analogs that we reported previously. We assessed pharmacokinetic profiles, lipid and thyroid-stimulating hormone (TSH) levels in rats, and cell culture activity of rexinoids in sterol regulatory element-binding protein (SREBP) induction and thyroid hormone inhibition assays. We also performed RNA sequencing of the brain tissues of rats that had been dosed with the compounds. We show here for the first time that potent rexinoid activity can be uncoupled from drastic lipid changes and thyroid axis variations, and we propose that rexinoids can be developed with improved side effect profiles than the parent compound, bexarotene (1).

Solar lentigines are common, benign, cosmetically disfiguring lesions. Available physical treatments are effective, but they are costly and carry risks of side-effects. To evaluate the efficacy and safety of a preparation containing undecylenoyl phenylalanine 2% in the topical treatment of solar lentigines. In total, 36 patients with solar lentigines of the hands were randomly assigned to apply the active preparation on one side and the vehicle alone on the other side, twice daily for 12 weeks. Patients were evaluated monthly for efficacy and safety. In all, 30 patients (28 women and 2 men; age range 47-75 years) completed the study. The duration of lesions ranged from 8 months to > 10 years. All patients responded partially on the side of the active treatment. Of the partial responders, 19 (63.3%) had moderate improvement and 11 (36.6%) had marked improvement. Improvement was evident from the first follow-up visit. On the side of the vehicle, 26 remained stable (86.6%) and 4 (13.3%) had partial improvement. There was a significant difference (P < 0.01) in efficacy of the active preparation vs. the vehicle. Using patient assessment ratings, 80% were 'much more satisfied/more satisfied' with the result. The reported side-effects were minor and included erythema and itching or burning on the side of active treatment. Undecylenoyl phenylalanine 2% is a novel depigmenting agent, which possibly acts as an alpha-melanocyte-stimulating hormone antagonist, thus inhibiting melaninogenesis. It achieved a significant lightening of the lesions with minimal side-effects. Most patients were satisfied with the improvement. Undecylenoyl phenylalanine 2% may represent a safe, effective and inexpensive therapeutic alternative for solar lentigines.

This study aimed to assess the incidence and difference of side effects among six courses of chemotherapy (C/T) in gynecological cancer patients. The study period was from Sep. 2010 to Dec. 2011 at the Kaohsiung Veterans General Hospital in Taiwan. The treating protocols, courses, and drugs of C/T in patient were considered according to the different malignant cancers and clinical conditions. The patient data of age, marriage status, education, religion, and experiences of C/T were collected. The patients' or their families' reported side effects of C/T were recorded daily from the beginning of C/T to the 10th day after C/T in each cycle and every course of C/T. Total 89 patients enrolled into the study received total 450 courses of C/T. The mean age was 54.52 ± 11.02. Ovarian cancer was the most common malignant disease (64.0%). The most often combination of drugs used was Taxol and carboplatin (40.9%). Patients complained peripheral numbness of limbs, with the highest incidence of 58.6%. The side effects with incidence about 50% were decreased fatigue (55.0%) and hair loss (49.9%). Other side effects with different levels of incidence were also noticed, such as lack of appetite, changes in taste, and muscle ache. The incidences of peripheral limb numbness and hair loss were increased with following courses of C/T. The high incidence of fatigue did not show variation between different courses of C/T. This study revealed the incidence of side effects and occurrence timing during C/T in patients with gynecological cancer. These data provide substantial information to patients and their families to understand the potential side effects of C/T courses, which might increase their compliance in receiving adjuvant C/T. Relieving the side effects in C/T would be important to improve their quality of daily life and treatment willingness.

This study examined whether psychosocial variables influenced patients' perception and experience of side effects of their medicines, how they coped with these experiences and the impact on medication adherence behaviour. A hospital-based mixed methods study using quantitative and qualitative approaches was conducted with hypertensive patients. Participants were asked about side effects, medication adherence, common psychological symptoms and coping mechanisms with the aid of standard questionnaires and an interview guide. The experiences of side effects-such as palpitations, frequent urination, recurrent bouts of hunger, erectile dysfunction, dizziness, cough, physical exhaustion-were categorized as no/low (39.75 %), moderate (53.0 %) and high (7.25 %). Significant relationships between depression (x (2) = 24.21, p < 0.0001), anxiety (x (2) = 42.33, p < 0.0001), stress (x (2) = 39.73, p < 0.0001) and side effects were observed. A logistic regression model using the adjusted results for this association is reported-depression [OR = 1.9 (1.03-3.57), p = 0.04], anxiety [OR = 1.5 (1.22-1.77), p ≤ 0.001] and stress [OR = 1.3 (1.02-1.71), p = 0.04]. Side effects significantly increased the probability of individuals to be non-adherent [OR = 4.84 (95 % CI 1.07-1.85), p = 0.04] with social factors, media influences and attitudes of primary care givers further explaining this relationship. Personal adoption of medication modifying strategies, espousing the use of complementary and alternative treatments and interventions made by clinicians were the main forms of coping with side effects. Results from this study show that, in addition to a biomedical approach, the experience of side effects has biological, social and psychological interrelations. The results offer more support for the need for a multi-disciplinary approach to healthcare where all forms of expertise are incorporated into health provision and patient care.

A systematic review of the psychiatric side-effects of efavirenz.

PubMed

2011-11-01

Concerns regarding the use of efavirenz in patients with a history of mental illness may predispose clinicians to not offer this agent to psychiatrically ill populations in spite of the convenience of once daily dosing, which can result in improved adherence in these at-risk populations. This systematic review examines the current data regarding the neuropsychiatric effects of efavirenz, and also attempts to provide guidance to clinicians using efavirenz to treat patients with mental illness. The review identified high rates of neuropsychiatric side effects including vivid dreams, insomnia and mood changes in approximately 50% of patients who initiate efavirenz. The effects begin quickly, commonly peak in the first 2 weeks, and are generally mild and transient in nature. Isolated case reports and uncontrolled data suggest higher rates of severe side effects; however, there is no clear evidence of a broadly increased risk of suicide or dangerous behavior for patients taking efavirenz as part of their antiretroviral regimen.

How tyrosine kinase inhibitors impair metabolism and endocrine system function: a systematic updated review.

2014-12-01

Tyrosine kinase inhibitors (TKIs) advent has deeply changed the outcome of chronic myeloid leukemia (CML) patients, with improved rates of response and overall survival. However, for this success some patients paid the price of a number of peculiar side effects, the so-called off-target side effects, specific for each one TKI. These effects are due to non-selective inhibition of other tyrosine kinase receptors, such as PDGFR, c-KIT, Src, VEGF. Consequences of this inhibition, some metabolic changes during the treatment with TKIs are reported. Aim of present review is to report metabolic changes and potential mechanisms involved in the pathogenesis related to imatinib, second (nilotinib and dasatinib) and third generation (bosutinib and ponatinib) TKIs.

Seizures associated with low-dose tramadol for chronic pain treatment

PubMed Central

Beyaz, Serbülent Gökhan; Sonbahar, Tuğba; Bayar, Fikret; Erdem, Ali Fuat

2016-01-01

The management of cancer pain still poses a major challenge for clinicians. Tramadol is a centrally acting synthetic opioid analgesic. Its well-known side effects include nausea, vomiting, and dizziness; seizures are a rare side effect. Some reports have found that tramadol triggers seizure activity at high doses, whereas a few preclinical studies have found that this seizure activity is not dose-related. We herein present a case involving a patient with laryngeal cancer who developed seizures while on low-dose oral tramadol. PMID:27212778

The authors present the case history of a patient suffering from hyperthyroidism. The diagnostic procedures revealed the presence of propylthiouracyl induced vasculitis with renal involvement, that recovered completely after the withdrawal of propylthiouracyl and corticosteroid treatment. Thereafter, the patient was treated with thiamasol, that caused agranulocytosis with fever. After transient litium carbonate therapy a succesful thyreoidectomy was performed. Cumulative serious side effects of antithyroid drugs are rare. This case highlights some of the challenges and complications encountered in the management of hyperthyroidism.

Although e-cigarette use ("vaping") is increasing in Canada, few attempts have been made to describe e-cigarette users ("vapers"). In this context, we conducted a study in Ottawa, Canada, to describe e-cigarette users' perceptions of the benefits, harms and risks of e-cigarettes. We also collected information on why, how and where they use e-cigarettes as well as information on side effects. A 24-item online survey was administered to individuals who purchased e-cigarettes or e-cigarette-related supplies at one of Ottawa's 17 e-cigarette shops. Descriptive analyses characterized respondents, and logistic regression models were fitted to evaluate the relationship between respondents' characteristics and their perception of e-cigarette harms. The mean age of the 242 respondents was 38.1 years (range: 16-70 years); 66% were male. Nearly all had smoked 100 or more cigarettes in their lifetime (97.9%). More than 80% indicated that quitting smoking was a very important reason for starting to use e-cigarettes and 60% indicated that they intend to stop using e-cigarettes at some point. About 40% reported experiencing some side effects within 2 hours of using e-cigarettes. Those who did not report experiencing any of the listed side effects had approximately 3.2 times higher odds of perceiving e-cigarettes as harmless than those who reported having side effects (odds ratio = 3.17; 95% confidence interval: 1.75-5.73). Our findings suggest that most e-cigarette users are using them to reduce or stop smoking cigarettes and perceive them as harmless. Due to our use of convenience sampling, the reader should be cautious in generalizing our findings to all Canadian e-cigarette users.

[Initial experiences with amisulpride, an in Germany novel, atypical neuroleptic drug in treatment of adolescents with psychiatric disorders].

PubMed

Göpel, C; Marcus, A

2001-08-01

In addition to conventional antipsychotic drugs, during the past decade an increasing number of atypical neuroleptics has been introduced in the treatment of juvenile schizophrenic and schizoaffective disorders. In 1999 Germany legalized the benzamide amisulpride for the treatment of acute and chronic schizophrenic symptoms. Preliminary treatment results are reported here. Ten adolescent cases are presented with regard to the efficacy, side effects and dosage of amisulpride. Preliminary results on the use of amisulpride are promising. The rate of side effects is tolerable. Amisulprise seems to constitute a useful alternative in the treatment of juvenile schizophrenia for those who suffer from intolerable side effects of classical or atypical neuroleptics. Controlled studies are warranted to further clarify its efficacy and safety in the treatment of adolescents.

Acne scars can be improved with various treatments such as topical creams, chemical peels, dermal fillers, microdermabrasion, laser, and radiofrequency devices. Some of these treatments especially lasers and deep chemical peels can have significant side effects such as post inflammatory hyperpigmentation in darker skin types. Fraxelated RF Laser devices have been reported to have lower incidence of side effects in all skin phototypes. Nine patients between ages 18 and 35 of various skin phototypes were selected from a private practice and treated with a RF fraxelated device (E-matrix) for acne scars. Outcomes were measured by physician observation, subjective feedback received by patients, and comparison of before and after photographs. In this small group of patients with various skin phototypes, fraxelated radiofrequency device improved acne scars with minimal side effects and downtime.

An Update on Safety and Side Effects of Cannabidiol: A Review of Clinical Data and Relevant Animal Studies

PubMed Central

Iffland, Kerstin; Grotenhermen, Franjo

2017-01-01

Abstract Introduction: This literature survey aims to extend the comprehensive survey performed by Bergamaschi et al. in 2011 on cannabidiol (CBD) safety and side effects. Apart from updating the literature, this article focuses on clinical studies and CBD potential interactions with other drugs. Results: In general, the often described favorable safety profile of CBD in humans was confirmed and extended by the reviewed research. The majority of studies were performed for treatment of epilepsy and psychotic disorders. Here, the most commonly reported side effects were tiredness, diarrhea, and changes of appetite/weight. In comparison with other drugs, used for the treatment of these medical conditions, CBD has a better side effect profile. This could improve patients' compliance and adherence to treatment. CBD is often used as adjunct therapy. Therefore, more clinical research is warranted on CBD action on hepatic enzymes, drug transporters, and interactions with other drugs and to see if this mainly leads to positive or negative effects, for example, reducing the needed clobazam doses in epilepsy and therefore clobazam's side effects. Conclusion: This review also illustrates that some important toxicological parameters are yet to be studied, for example, if CBD has an effect on hormones. Additionally, more clinical trials with a greater number of participants and longer chronic CBD administration are still lacking. PMID:28861514

The retention of lacosamide in patients with epilepsy and intellectual disability in three specialised institutions.

We describe the effectiveness of lacosamide as adjunctive therapy in patients with epilepsy and an intellectual disability. This information is relevant, as few data exist pertaining to this population with a high prevalence of (intractable) epilepsy. We performed a retrospective study in three specialised institutions. Inclusion criteria were (1) focal onset or symptomatic generalized (2) therapy-resistant epilepsy, (3) intellectual disability and (4) residence in a care-facility for people with intellectual disabilities (PWID). The primary outcome variables were the retention rates of lacosamide, estimated through Kaplan-Meier survival analysis. Secondary outcomes were reported seizure control, side effects and clinical factors influencing discontinuation. One hundred and thirty-two patients were included. The median retention time of lacosamide in our cohort was four years. The estimated one-, two- and three-year retention rates of lacosamide were 64%, 57% and 56% respectively. Severity of intellectual disability and seizure type did not influence whether lacosamide was continued. In 48.5% of patients, a reduction of seizure activity was reported. Side effects were at least part of the reason for discontinuing treatment in 26.5% of all patients. Common side effects were tiredness/somnolence (in 30.3%), aggression/agitation (24.2%), and instable gait (15.2%). Five deaths during follow-up were considered unlikely to be related to the use of lacosamide. One patient died unexpectedly within two months of treatment onset, probably this was a case of SUDEP. These retention rates of lacosamide in PWID are similar to rates of previously registered anti-epileptic drugs in PWID. Behavioural side effects were noted in a high proportion compared to the general literature on lacosamide. Other side effects were in line with this literature. Lacosamide seems effective and safe for PWID and refractory epilepsy. Copyright © 2017 British Epilepsy Association. Published by Elsevier Ltd. All rights reserved.

Informing the introduction of contraceptive implants in the Pacific: a mixed methods study of contraceptive beliefs and behaviours in Tonga.

To explore the knowledge and attitudes underlying contraceptive use and non-use among Tongan adults and investigate the potential acceptability of contraceptive implants. A mixed methods study was conducted that used two focus groups and a short self-completed survey (n=109). Participants were recruited from a Tongan non-governmental sexual and reproductive health clinic. Contraceptive method discontinuation was high among the study group, with reasons for discontinuation often relating to misconceptions circulating in the community about the side effects of contraceptives. A high proportion (38%) reported using 'natural' contraceptive methods. A total of 47% of survey participants reported having heard of implants and 37% indicated they would be willing to try them. Current Tongan contraceptive uptake and continuation is hampered by misconceptions about side effects of methods and their risks, particularly among long-acting and reversible methods. Contraceptive implants may be acceptable to Tongans given their arm placement, reversibility and long-lasting effect. Efforts to improve contraceptive continuation in Tonga should focus on improving counselling on potential side effects for all methods. The introduction of contraceptive implants as an additional long-acting reversible method should be considered. © 2015 Public Health Association of Australia.

People with epilepsy are at increased risk of accidents and injuries but, despite several studies on this subject, data regarding preventable causes are still contradictory. The aim of this study was to investigate the relationship between injuries, side effects of antiepileptic drugs (AEDs) and depression. Data from a consecutive sample of adult patients with epilepsy attending the outpatient clinics at St George's University Hospital in London were included. All patients were asked if they had had any injury since the last clinic appointment and completed the Liverpool Adverse Event Profile (LAEP) and Neurological Disorders Depression Inventory for Epilepsy. Among 407 patients (243 females, mean age 43.1 years), 71 (17.4%) reported injuries since the last appointment. A two-step cluster analysis revealed two clusters with the major cluster (53.5% of the injured group) showing a total score for LAEP ≥45, a positive Neurological Disorders Depression Inventory for Epilepsy screening and presence of AED polytherapy. A total score for LAEP ≥45 was the most important predictor. Antiepileptic drug treatment should be reviewed in patients reporting injuries in order to evaluate the potential contribution and burden of AED side effects. © 2017 EAN.

Continued diversification and use of new psychoactive substances (NPS) across Europe remains a public health challenge. The study describes health and social consequences of recent NPS use as reported in a survey of marginalised, nightlife and online NPS users in the Netherlands, Hungary, Portugal, Ireland, Germany and Poland ( n  = 3023). Some respondents were unable to categorise NPS they had used. Use of ' herbal blends ' and ' synthetic cannabinoids obtained pure ' was most reported in Germany, Poland and Hungary, and use of ' branded stimulants ' and ' stimulants/empathogens/nootropics obtained pure ' was most reported in the Netherlands. Increased heart rate and palpitation, dizziness, anxiety, horror trips and headaches were most commonly reported acute side effects. Marginalised users reported substantially more acute side effects, more mid- and long-term mental and physical problems, and more social problems. Development of country-specific NPS awareness raising initiatives, health and social service needs assessments, and targeted responses are warranted.

The role of intravenous immunoglobulin in treatment of mucous membrane pemphigoid: A review of literature

PubMed Central

Tavakolpour, Soheil

2016-01-01

Background: Mucous membrane pemphigoid (MMP) is considered an autoimmune blistering disease that predominantly affects mucous membranes. Various treatments are available for controlling the diseases, but not all of them may respond. Materials and Methods: PubMed and Google Scholar were searched for all the associated studies until 2015, using the keywords such as “cicatricial pemphigoid” or “ocular pemphigoid” or “mucous membrane pemphigoid” or “MMP” and “intravenous immunoglobulin” or “IVIg” to find all the relevant studies. The last search update was for September 2, 2015. Among the searched items, only English studies were included in the review. Results: After excluding nonrelevant studies, 13 studies with a total number of seventy patients with MMP who were under treatment with IVIg were analyzed. The 65 patients responded completely, one did not respond, two had partially responded, and the remaining two patients stopped IVIg therapy, which resulted in ocular cicatricial pemphigoid progression. Majority of the studies reported mild adverse effects while two of them did not report any unwanted side effect. The most common side effect was headache, followed by nausea. Most of the patients who had a cessation of IVIg therapy before achieving clinical remission experienced the disease progression. Conclusion: Overall, it can be concluded that IVIg therapy was very helpful in treatment of MMP patients who did not respond to conventional therapy or stopped using them for various side effects. Adverse effects associated with IVIg therapy were considerably lower than conventional therapy that can lead toward treatment with this agent in patients who suffer from severe side effects.

Cutaneous mucormycosis is an uncommon disease and occurs rarely in immunocompetent patients. We reported the case of a 37-year-old man presenting with a skin lesion on the left side of the chest wall with no history of trauma or primary diseases. He was firstly misdiagnosed as tuberculosis and the proper treatment was thus delayed. Histopathological examination and fungal culture of the lesion confirmed cutaneous mucormycosis. The isolate was identified as Rhizopus microspores by ITS sequencing. The patient was treated with oral posaconazole 400 mg bid for 150 days. The patient recovered satisfactorily. No recurrence was found during the follow-up and no side effect of liver function was found. This case helps doctors to consider the possibility of serious fungal infection in immunocompetent patients. It also suggested that posaconazole could be an alternative choice for the treatment of mucormycosis considering the severe side effect of Amphotericin B.

Pain therapy with oxycodone/naloxone prolonged-release combination: case report.

Pain afflicts patients suffering from many chronic diseases and is present in 80% of cases of patients with advanced cancer who suffer from persistent pain. The aim of the pain treatment is to achieve the maximum analgesic effect while minimizing side effects. The main analgesic agent - morphine is unfortunately a therapy associated with gastrointestinal side effects. It appears that the combination of oxycodone and naloxone available as Targin(®) (Mundipharma) is an alternative. The paper presents a case of a 45-year-old patient who was treated effectively with oxycodone/naloxone prolonged-release tablets. This treatment has proven to be effective in providing pain and constipation control.

Impact of brand or generic labeling on medication effectiveness and side effects.

2016-02-01

Branding medication with a known pharmaceutical company name or product name bestows on the drug an added assurance of authenticity and effectiveness compared to a generic preparation. This study examined the impact of brand name and generic labeling on medication effectiveness and side effects. 87 undergraduate students with frequent headaches took part in the study. Using a within-subjects counterbalanced design, each participant took tablets labeled either as brand name "Nurofen" or "Generic Ibuprofen" to treat each of 4 headaches. In reality, half of the tablets were placebos, and half were active ibuprofen (400 mg). Participants recorded their headache pain on a verbal descriptor and visual analogue scale prior to taking the tablets, and again 1 hour afterward. Medication side effects were also reported. Pain reduction following the use of brand name labeled tablets was similar in active ibuprofen or a placebo. However, if the tablets had a generic label, placebo tablets were significantly less effective compared to active ibuprofen. Fewer side effects were attributed to placebo tablets with brand name labeling compared to the same placebo tablets with a generic label. Branding of a tablet appears to have conferred a treatment benefit in the absence of an active ingredient, while generic labeled tablets were substantially less effective if they contained no active ingredient. Branding is also associated with reduced attribution of side effects to placebo tablets. Future interventions to improve perceptions of generics may have utility in improving treatment outcomes from generic drugs. (c) 2016 APA, all rights reserved).

Association between side air bags and risk of injury in motor vehicle collisions with near-side impact.

Side air bags (SABs) have been introduced in an attempt to reduce the risk of injury in near-side-impact motor vehicle collisions (MVCs). The impact of SABs on MVC-related mortality and morbidity has yet to be evaluated with a large population-based study. The objective of this study was to assess the effectiveness of SABs in reducing the risk of injury or death in near-side-impact MVCs. A retrospective study investigated outboard front seat occupants involved in police-reported, near-side-impact MVCs using data from the General Estimates System (1997-2000). The risk of MVC-related nonfatal and fatal injury for occupants of vehicles with and without SABs was compared. Front seat occupants of vehicles with SABs had a risk of injury similar to that of occupants of vehicles without SABs (risk ratio [RR], 0.96; 95% CI confidence interval [CI], 0.79-1.15). Adjustment for the potentially confounding effects of age, gender, seat belt use, seating position, damage severity and location, and vehicle body type did not meaningfully affect the association (RR, 0.90; 95% CICI, 0.76-1.08). There is no association between the availability of SABs and overall injury risk in near-side-impact MVCs. Future research is necessary to determine the effectiveness of SABs in preventing the injuries for which they were specifically designed.

Focused Study on the Quiet Side Effect in Dwellings Highly Exposed to Road Traffic Noise

2012-01-01

This study provides additional evidence for the positive effect of the presence of a quiet façade at a dwelling and aims at unraveling potential mechanisms. Locations with dominant road traffic noise and high Lden-levels at the most exposed façade were selected. Dwellings both with and without a quiet façade were deliberately sought out. Face-to-face questionnaires (N = 100) were taken to study the influence of the presence of a quiet side in relation to noise annoyance and sleep disturbance. As a direct effect, the absence of a quiet façade in the dwelling (approached as a front-back façade noise level difference smaller than 10 dBA) leads to an important increase of at least moderately annoyed people (odds-ratio adjusted for noise sensitivity equals 3.3). In an indirect way, a bedroom located at the quiet side leads to an even stronger reduction of the self-reported noise annoyance (odds-ratio equal to 10.6 when adjusted for noise sensitivity and front façade Lden). The quiet side effect seems to be especially applicable for noise sensitive persons. A bedroom located at the quiet side also reduces noise-induced sleep disturbances. On a loud side, bedroom windows are more often closed, however, conflicting with the preference of dwellers. PMID:23330222

The injectable progestogen only contraceptive is a widely accepted method of contraception in our environment and very Iittle has been reported on its complications in our environment. The aim of the study was to highlight the complications associated with use of injectable Medroxyprogesterone Acetate and Norethisterone Enanthate in dients at the University of Part-Harcourt Teachng Hospital, Port-Harcou, south-south Nigeria. It was a 5 rear year retrospective study of the clients who accepted and used progestogen only injectable contraceptives (depot medroxyprogesterone acetate noerthistherone enantate) at the family planning units of the University of Port Horcowt Teaching Hospital between 1st January 2000 and 31st December 2004. The case flies of these clients were retrieved and their data extracted. The informolion included the dients sociodemographic characteristics, the types doses of of injectable contraceptives received and the side effects reported at the follow up visits. The data was coded and entered into a data bank and analysed using SPSS for windows 11.0 version. Seven hundred and seventy seven (777) injectable contraceptive acceptors out of the 1720 contraceptive acceptors during the study period. This accounted for 45.17% of the new acceptors over the 5 years period, making the injectable contraceptives the most commonly used method of birth control in UPTH. Five hundred and five (505) clients took depot medroxyprogesterone acetate (DMPA) while 272 used norethesterone enanthate (NE-ET). The mean age of the injectable contraceptive users was 31.31 +/- 5.5 years and the mean parity was 5.5 +/- 2.5 deliveries. The users reported multiple side effects with 579 episodes. Secondary amenorrhea was the commonest side effect occurring in 350 (45.34%) clients. Others were hypertension in 17 (2.94%) and metabolic disturbances in 14 (2.41%). Injectable progestogen only contraceptive is associated with multiple side effects, with secondary amenorrhoea being the most common. The contraceptive failure rate of this method in our women is low.

Braver, Elisa R; Kyrychenko, Sergey Y

2004-03-15

Side air bags, a relatively new technology designed to protect the head and/or torso in side-impact collisions, are becoming increasingly common in automobiles. Their efficacy in preventing US driver deaths among cars struck on the near (driver's) side was examined using data from the Fatality Analysis Reporting System and the General Estimates System. Risk ratios for driver death per nearside collision during 1999-2001 were computed for head/torso and torso-only side air bags in cars from model years 1997-2002, relative to cars without side air bags. Confounding was addressed by adjusting nearside risk ratios for front- and rear-impact mortality, which is unaffected by side air bags. Risk ratios were 0.55 (95% confidence interval: 0.43, 0.71) for head/torso air bags and 0.89 (95% confidence interval: 0.79, 1.01) for torso-only air bags. Risk was reduced when cars with head/torso air bags were struck by cars/minivans (significant) or pickup trucks/sport utility vehicles (nonsignificant). Risk was reduced in two-vehicle collisions and among male drivers and drivers aged 16-64 years. Protective effects associated with torso-only air bags were observed in single-vehicle crashes and among male and 16- to 64-year-old drivers. Head/torso side air bags appear to be very effective in reducing nearside driver deaths, whereas torso-only air bags appear less protective.

Bridging the boundaries between scientists and clinicians-mechanistic hypotheses and patient stories in risk assessment of drugs.

PubMed

Rocca, Elena

2017-02-01

The cultural divide between scientists and clinicians has been described as undermining the advance of medical science, by hindering the production of practice-relevant research and of research-informed clinical decisions. Here, I consider the field of post-marketing risk assessment of drugs as an example of strict interdependence between basic biomedical research, clinical research, and clinical evaluation and show how it would benefit from a closer collaboration between scientists and clinicians. The risk assessment of drugs after their marketing relies on spontaneous adverse effect reports to drug agencies and on peer-reviewed case reports. I emphasize the importance of qualitative analysis of such reports for the improvement of mechanistic understanding of harmful effects of drugs. I argue that mechanistic explanations of drug effects are at least as important as determination of their frequency, in order to establish causation. An ideal risk assessment, then, verifies not only the frequency of undesired effects but also why and how the harm happens. For this purpose, the frequency or novelty of the unintended outcome, although contextually indicative, should not determine the epistemic value of a report. Details about the context that generated an unexpected outcome, instead, can offer the chance of improving causal understanding about how the intervention works. This is illustrated through examples from medical research. Mechanistic understanding is a domain of joint collaboration among (1) clinicians, in charge of detailed, qualitative reporting of patient stories about side effects, (2) qualitative clinical researchers, in charge of analyzing clinical contexts or harmful effects and formulating explanatory hypotheses, and (3) basic biomedical researchers, in charge of verifying such hypotheses. In addition, direct information flow can on one side focus clinicians' attention on knowledge gaps about drugs/effects where more research is needed, while on the other side create a more contextualized concept of mechanism among scientists. © 2016 John Wiley & Sons, Ltd.

Clonidine is effective for the treatment of primary idiopathic hyperhidrosis and hot flushes: a case report.

PubMed

Albadrani, Ahmed

2017-01-17

While primary hyperhidrosis can be seen in men, accompanying hot flushes is rarely seen in men. Primary hyperhidrosis is thought to be related to overactivity of the sympathetic nervous system while hot flushes are believed to be related to altered peripheral vascular reactivity and a narrowed thermoregulatory zone. I report the case of a 29-year-old man of Arab origin who presented to a dermatology clinic with a complaint of generalized sweating, with heavier involvement of his inguinal region, axilla, and lower back. His complaint was associated with a transient hot sensation and erythema over the affected areas. He did not respond to topical antiperspirants containing aluminum chloride, topical aluminum chloride, or to botulinum toxin A injected in both inguinal areas. He was then referred to an endocrinology clinic to rule out secondary causes of hyperhidrosis and hot flushes; a primary diagnosis was confirmed. He did not respond to oral glycopyrrolate and additionally was complaining of its anticholinergic side effects. The glycopyrrolate was then replaced with oral clonidine 0.15 mg twice a day. Clonidine was well tolerated without remarkable side effects and he quickly started to feel marked improvement which was maintained for 2 years. I report an atypical presentation of primary hyperhidrosis and hot flushes that was effectively controlled by clonidine without remarkable side effects. Further research on a large number of patients may be required before recommending clonidine in similar conditions.

To explore the impact of Glivec related side effects on daily life in Chinese patients with chronic myeloid leukemia (CML) in the chronic phase (CP). From May to November in 2014, anonymous questionnaires were distributed to adult CML patients who were receiving tyrosine kinase inhibitors (TKI) treatment in China. The impact of TKI related side effects on daily life were assessed by the score of 1 (no impact) to 5 (high impact) from patient self- report. Data from 548 respondents in the CP on Glivec were collected. 303(55%) cases were male with the median age of 40 years (range, 18 to 88 years). 437 (80% ) cases started Glivec treatment within one year after diagnosis with a median treatment duration of 3 years (range, <1 to 13 years), 442 (81%) respondents achieved complete cytogenetic response (CCyR), and 261 (48% ) complete molecular response (CMR). The most common Glivec related adverse effects were edema (n=278, 51% ), fatigue (n=218, 40% ), gastrointestinal disorders (n=190, 35%), muscle cramps (n=118, 22%), skin color changes (n=118, 22%), weight gain (n=71, 13%), rash (n=60, 11%), hepatic function abnormality (n=55, 10%), and cytopenia (n=38, 7%). Among the 548 respondents, the mean score of Glivec-related side effects on daily life was 2.4±1.2. There was no negative impact of Glivec related side effects on daily life in 161(29%) respondents. 295 (54% ) and 92 (17% ) respondents reported slightly or moderately (2- 3 score) and significantly decreased (4-5 score) daily life, respectively. Multivariate analysis showed that Glivec treatment duration < 4 years (OR=1.9, 95% CI 1.3- 2.6;P<0.001) and Glivec related side effects including fatigue (OR=2.9, 95% CI 2.1-4.1;P<0.001), edema (OR=2.2, 95% CI 1.6-3.1;P<0.001), gastrointestinal disorders (OR= 2.6, 95% CI 1.9- 3.7;P<0.001), rash (OR=2.1, 95% CI 1.2- 3.4; P=0.0051) and hepatic function abnormality (OR=2.3, 95% CI 1.4-3.9;P=0.0013) were factors associated with serious negative effect on daily life. Daily life was impaired seriously in a minority of Chinese CML patients who received Glivec, especially in the first 4 years of treatment. Fatigue, edema, gastrointestinal disorders, rash and hepatic function abnormality were side effects associated with negative impact on patients' daily life.

TOPEX Radar Altimeter Engineering Assessment Report Final Update-Side B Turn-On to End-of-Mission on October 9, 2005

This is the thirteenth and final report in a series of TOPEX Radar Altimeter Engineering Assessment Reports. The initial TOPEX Radar Altimeter Engineering Assessment Report, in February 1994, presented performance results for the NASA Radar Altimeter on the TOPEX/POSEIDON spacecraft, from its launch in August 1992 to February 1994. Since the time of that initial report and prior to this report, there have been eleven interim supplemental Engineering Assessment Reports, issued in March 1995, May 1996, March 1997, June 1998, August 1999, September 2000, June 2001, March 2002, May 2003, April 2004 and September 2005. The sixth supplement in September 2000 was the first assessment report that addressed Side B performance, and presented the altimeter performance from Side B turn-on until the end of calendar year 1999. This report extends the performance assessment of Side B to the final collection of data on October 9, 2005, and includes the performance assessment of Jason-1, the TOPEX follow-on mission, launched on December 7, 2001. This report provides some comparisons of Side A and Side B performance.

Bimatoprost is a prostaglandin analogue used topically in the treatment of glaucoma. Commonly known side effects include eyelash growth, iris pigmentation and conjunctival hyperemia. While pseudomyopia is reported to be caused by parasympathomimetics, such an effect precipitated by bimatoprost has not yet been reported. We report a case demonstrating pseudomyopia and accommodative spasm caused after starting bimatoprost 0.03% in a young patient with glaucoma. 2015 BMJ Publishing Group Ltd.

Pain remains a pervasive problem throughout medicine, transcending all specialty boundaries. Despite the extraordinary insights into pain and its mechanisms over the past few decades, few advances have been made with analgesics. Most pain remains treated by opiates, which have significant side effects that limit their utility. We now describe a potent opiate analgesic lacking the traditional side effects associated with classical opiates, including respiratory depression, significant constipation, physical dependence, and, perhaps most important, reinforcing behavior, demonstrating that it is possible to dissociate side effects from analgesia. Evidence indicates that this agent acts through a truncated, six-transmembrane variant of the G protein-coupled mu opioid receptor MOR-1. Although truncated splice variants have been reported for a number of G protein-coupled receptors, their functional relevance has been unclear. Our evidence now suggests that truncated variants can be physiologically important through heterodimerization, even when inactive alone, and can comprise new therapeutic targets, as illustrated by our unique opioid analgesics with a vastly improved pharmacological profile.

Due to their specific properties and pharmacokinetics, nanomedicinal products (NMPs) may present different toxicity and side effects compared to non-nanoformulated, conventional medicines. To facilitate the safety assessment of NMPs, we aimed to gain insight into toxic effects specific for NMPs by systematically analyzing the available toxicity data on approved NMPs in the European Union. In addition, by comparing five sets of products with the same active pharmaceutical ingredient (API) in a conventional formulation versus a nanoformulation, we aimed to identify any side effects specific for the nano aspect of NMPs. The objective was to investigate whether specific toxicity could be related to certain structural types of NMPs and whether a nanoformulation of an API altered the nature of side effects of the product in humans compared to a conventional formulation. The survey of toxicity data did not reveal nanospecific toxicity that could be related to certain types of structures of NMPs, other than those reported previously in relation to accumulation of iron nanoparticles (NPs). However, given the limited data for some of the product groups or toxicological end points in the analysis, conclusions with regard to (a lack of) potential nanomedicine-specific effects need to be considered carefully. Results from the comparison of side effects of five sets of drugs (mainly liposomes and/or cytostatics) confirmed the induction of pseudo-allergic responses associated with specific NMPs in the literature, in addition to the side effects common to both nanoformulations and regular formulations, eg, with liposomal doxorubicin, and possibly liposomal daunorubicin. Based on the available data, immunotoxicological effects of certain NMPs cannot be excluded, and we conclude that this end point requires further attention. PMID:28883724

Clinically insubstantial cognitive side effects of bitemporal electroconvulsive therapy at 0.5 msec pulse width.

PubMed

Warnell, Ronald L; Swartz, Conrad M; Thomson, Alice

2011-11-01

We measured cognitive side effects from bitemporal electroconvulsive therapy (ECT) using stimuli of 0.5 msec pulse width 900 milliamperes (mA). Mini-Mental State Exam (MMSE) and 21-item Hamilton Rating Scale for Depression (HRSD-21) were rated within 36 hours before and 36 hours after a series of 6 bitemporal ECT sessions on 15 patients age ≥45. MMSE remained high after ECT (pre-ECT mean 29, standard deviation [SD] 1.60, post-ECT mean 28.53, SD 1.36) with no significant change. The mean HRSD-21 fell from 27.5 to 16.3. Post-ECT MMSE was significantly and markedly higher than in previous studies of bitemporal ECT; all had used ECT stimuli of pulse width at least 1 msec. With stimuli of 0.5 msec pulse width and 900 mA, 6 bitemporal ECTs did not decrease MMSE score. This result leaves no opportunity for further decrease in basic cognitive side effects, and complements published reports of stronger physiological effects with stimuli of 0.5 msec pulse width and 900 mA. ECT stimuli of 0.5 msec pulse width and 900 mA are more desirable than wider pulse widths. Six bitemporal ECT sessions using these stimuli generally will not have more cognitive side effects than treatments with other placements, allowing maintenance of full efficacy with clinically insubstantial side effects.

Cigarette smoking is the largest preventable cause of death worldwide. No systematic review is available on the situation of the smoking in Iran, so we decided to provide an overview of the studies in the field of smoking in Iranian populations. Published Persian-language papers of all types until 2009 indexed in the IranMedex (http://www.iranmedex.com) and Magiran (http://www.magiran.com). Reports of World Health Organization were also searched and optionally employed. The studies concerning passive smoking or presenting the statistically insignificant side effects were excluded. Databases were searched using various combinations of the following terms: cigarette, smoking, smoking cessation, prevalence, history, side effects, and lung cancer by independent reviewers. All the 83 articles concerning the prevalence or side effects of the smoking habit in any Iranian population were selected. The prevalence rate of daily cigarette smoking and the 95% confidence interval as well as smoking health risk associated odds ratio (OR) were retrieved from the articles or calculated. The reported prevalence rates of the included studies, the summary of smoking-related side effects and the ORs (95%CI) of smoking associated risks and the available data on smoking cessation in Iran have been shown in the article. Because of lack of certain data, special studies on local pattern of tobacco use in different districts, about the relationship between tobacco use and other diseases, especially non communicable diseases, and besides extension of smoking cessation strategies, studies on efficacy of these methods seems to be essential in this field.

We report for the first time on hair regrowth in alopecia areata of the scalp achieved with the 308-nm xenon-chloride excimer laser in a prospective side-by-side trial. The alopecia areata had shown progression over a period of three years, and various treatments had not been effective. Out of a number of affected areas, one representative lesion was chosen; one half of it was treated, the other half remained untreated. After 27 sessions (200 - 4000 mJ/cm2, cumulative dose 52.6 J/cm2) over 3 months, only the treated area showed hair growth; which suggests that this was most probably not a spontaneous remission.

The post mortem electrochemical analysis, including charge-discharge and electrochemical impedance spectroscopy (EIS) measurements, are critical steps for revealing the failure mechanisms of commercial lithium-ion batteries (LIBs). These post measurements usually require the reassembling of coin-cell with electrode which is often double-side-coated in commercial LIBs. It is difficult to use such double-side-coated electrode to perform accurate electrochemical measurements because the back side of the electrode is coated with active materials, rather than single-side-coated electrode that is often used in coin-cell measurements. In this study, we report a facile tape-covering sample preparation method, which can effectively suppress the influence of back side of the double-side-coated electrodes on capacity and EIS measurements in coin-cells. By tape-covering the unwanted side, the areal capacity of the desired investigated side of the electrode has been accurately measured with an experimental error of about 0.5% at various current densities, and accurate EIS measurements and analysis have been conducted as well.

Novel painkillers are urgently needed. The activation of opioid receptors in peripheral inflamed tissue can reduce pain without central adverse effects such as sedation, apnoea, or addiction. Here, we use an unprecedented strategy and report the synthesis and analgesic efficacy of the standard opioid morphine covalently attached to hyperbranched polyglycerol (PG-M) by a cleavable linker. With its high-molecular weight and hydrophilicity, this conjugate is designed to selectively release morphine in injured tissue and to prevent blood-brain barrier permeation. In contrast to conventional morphine, intravenous PG-M exclusively activated peripheral opioid receptors to produce analgesia in inflamed rat paws without major side effects such as sedation or constipation. Concentrations of morphine in the brain, blood, paw tissue, and in vitro confirmed the selective release of morphine in the inflamed milieu. Thus, PG-M may serve as prototype of a peripherally restricted opioid formulation designed to forego central and intestinal side effects.

The clinical efficacy and the safety of chronic oral administration of cisapride, a new gastrointestinal prokinetic agent, (10 mg tid) and clebopride (0.5 mg tid) was assayed in 48 outpatients affected with functional dyspepsia, in a randomized double-blind study. Each of the drugs induced a significant reduction in dyspeptic symptoms after 2 and 4 weeks (p less than 0.001). Two patients, given clebopride, dropped out of the study because of severe side effects during the first week of treatment. Mild adverse reactions were reported in 6 out of 23 cisapride-treated patients and in 10 out of 20 clebopride-treated patients who completed the study. The most common side effect of cisapride was diarrhoea and that of clebopride was drowsiness. Cisapride appears to be as effective as clebopride in reducing dyspeptic symptoms and seems to induce less severe side effects.

Opioids are widely used to treat millions suffering from pain, but their analgesic utility is limited due to associated side effects. Herein we report the development and evaluation of a chemical probe exhibiting analgesia and reduced opioid-induced side effects. This compound, kurkinorin (5), is a potent and selective μ-opioid receptor (MOR) agonist (EC 50 = 1.2 nM, >8000 μ/κ selectivity). 5 is a biased activator of MOR-induced G-protein signaling over β-arrestin-2 recruitment. Metadynamics simulations of 5's binding to a MOR crystal structure suggest energetically preferred binding modes that differ from crystallographic ligands. In vivo studies with 5 demonstrate centrally mediated antinociception, significantly reduced rewarding effects, tolerance, and sedation. We propose that this novel MOR agonist may represent a valuable tool in distinguishing the pathways involved in MOR-induced analgesia from its side effects.

Drug-induced hair loss may occur as a side effect in patients treated with valproate. However, few studies have reported a relationship between the blood levels of valproate and the occurrence of hair loss. We report three cases of alopecia that occurred in patients who received sodium valproate for mental disorders. In all three cases, alopecia appeared after long-term valproate exposure with a plasma concentration of 100 µg/ml approximately. However, the alopecia resolved in all cases after dose reduction or treatment discontinuation. Therefore, alopecia may develop in patients with chronic exposure to high plasma concentrations of valproate. Based on these findings, we believe that patients with high plasma concentrations of valproate should be closely monitored for the occurrence of side effects, particularly alopecia.

The east side of the Uncompahgre River Basin has been a known contributor of dissolved selenium to recipient streams. Discharge of groundwater containing dissolved selenium contributes to surface-water selenium concentrations and loads; however, the groundwater system on the east side of the Uncompahgre River Basin is not well characterized. The U.S. Geological Survey, in cooperation with the Colorado Water Conservation Board and the Bureau of Reclamation, has established a groundwater-monitoring network on the east side of the Uncompahgre River Basin. Thirty wells total were installed for this project: 10 in 2012 (DS 923, http://dx.doi.org/10.3133/ds923), and 20 monitoring wells were installed during April and June 2014 which are presented in this report. This report presents location data, lithologic logs, well-construction diagrams, and well-development information. Understanding the groundwater system can provide managers with an additional metric for evaluating the effectiveness of salinity and selenium control projects.

The ITER low field side reflectometer faces some unique design challenges, among which are included the effect of relativistic electron temperatures and refraction of probing waves. This paper utilizes GENRAY, a 3D ray tracing code, to investigate these effects. Using a simulated ITER operating scenario, characteristics of the reflected millimeter waves after return to the launch plane are quantified as a function of a range of design parameters, including antenna height, antenna diameter, and antenna radial position. Results for edge/SOL measurement with both O- and X-mode polarizations using proposed antennas are reported.

Volvo and Infiniti drivers' experiences with select crash avoidance technologies.

2010-06-01

Vehicle-based crash avoidance systems can potentially reduce crashes, but success depends on driver acceptance and understanding. This study gauged driver use, experience, and acceptance among early adopters of select technologies. Telephone interviews were conducted in early 2009 with 380 owners of Volvo vehicles equipped with forward collision warning with autobrake, lane departure warning, side-view assist, and/or active bi-xenon headlights and 485 owners of Infiniti vehicles with lane departure warning/prevention. Most owners kept systems turned on most of the time, especially forward collision warning with autobrake and side-view assist. The exception was lane departure prevention; many owners were unaware they had it, and the system must be activated each time the vehicle is started. Most owners reported being safer with the technologies and would want them again on their next vehicles. Perceived false or unnecessary warnings were fairly common, particularly with side-view assist. Some systems were annoying, especially lane departure warning. Many owners reported safer driving behaviors such as greater use of turn signals (lane departure warning), increased following distance (forward collision warning), and checking side mirrors more frequently (side-view assist), but some reported driving faster at night (active headlights). Despite some unnecessary or annoying warnings, most Volvo and Infiniti owners use crash avoidance systems most of the time. Among early adopters, the first requirement of effective warning systems (that owners use the technology) seems largely met. Systems requiring activation by drivers for each trip are used less often. Owner experience with the latest technologies from other automobile manufacturers should be studied, as well as for vehicles on which technologies are standard (versus optional) equipment. The effectiveness of technologies in preventing and mitigating crashes and injuries, and user acceptance of interfaces, should be examined as more vehicles with advanced technologies penetrate the fleet.

Splenic trauma as an adverse effect of torso-protecting side airbags: biomechanical and case evidence.

2009-10-01

Injury mechanisms from frontal airbags, first identified in anecdotal reports, are now well documented for pediatric, small female, and out-of-position occupants. In contrast, torso side airbags have not yet been consistently associated with specific injury risks in field assessments. To determine possible torso side airbag-related injuries, the present study identified crashes involving side airbags from reports within the CIREN, NASS, and SCI databases. Injury patterns were compared to patterns from lateral crashes in absence of side airbag. Splenic trauma (AIS 3+) was found present in five cases of torso side airbag deployment at lower impact severity (as measured by velocity change and compartment intrusion) than cases of splenic trauma without side airbag. Five additional cases were found to contain similar injury patterns but occurred with greater crash severity. To supplement case analyses, full scale sled tests were conducted with a THOR-NT dummy and cadaveric specimen. Four THOR tests with door- and seat-mounted torso side airbags confirmed that out-of-position (early inflation stage) airbag contact elevated thoracic injury metrics compared to optimal (fully inflated) contact. Out-of-position seat-mounted airbag deployment also produced AIS 3 splenic trauma in the cadaveric specimen. Due to potentially sudden or delayed onset of intraperitoneal hemorrhage and hypovolemic shock following splenic trauma, further biomechanical investigation of this anecdotal evidence is essential to identify injury mechanisms, prevention techniques, and methods for early diagnosis.

Yellow fever (YF) may be very serious, with mortality reaching 50%. Live attenuated virus YF vaccine (YFV) is effective, but may present, although rare, life-threatening side effects and is contraindicated in immunocompromised patients. However, some transplant patients may inadvertently receive the vaccine. A questionnaire was sent to all associated doctors to the Brazilian Organ Transplantation Association through its website, calling for reports of organ transplanted patients who have been vaccinated against YF. Twelve doctors reported 19 cases. None had important side effects. Only one had slight reaction at the site of YFV injection. Eleven patients were male. Organs received were 14 kidneys, 3 hearts, and 2 livers. Twelve patients received organs from deceased donors. Mean age at YFV was 45.6 ± 13.6 years old (range 11-69); creatinine: 1.46 ± 0.62 mg/dL (range 0.8-3.4); post-transplant time: 65 ± 83.9 months (range 3-340); and time from YFV at the time of survey: 45 ± 51 months (range 3-241). Immunosuppression varied widely with different drug combinations: azathioprine (7 patients), cyclosporine (8), deflazacort (1), mycophenolate (10), prednisone (11), sirolimus (3), and tacrolimus (4). YFV showed no important side effects in this cohort of solid organ transplanted patients. However, owing to the small number of studied patients, it is not possible to extend these findings to the rest of the transplanted population, assuring safety. Therefore, these data are not strong enough to safely recommend YFV in organ transplanted recipients, as severe, even life-threatening side effects may occur. © 2011 John Wiley & Sons A/S.

What is the role of combination drug therapy in the treatment of overactive bladder? ICI-RS 2014.

The role of combination therapy using oral antimuscarinic medications for the treatment of overactive bladder was proposed at the 2014 International Consultation on Incontinence-Research Society in Bristol, UK to identify key factors to consider when making clinical decisions and to guide future research design. Combination therapy is justified if monotherapy is associated with suboptimal efficacy or bothersome side effects. Combination therapy has the potential to improve efficacy with fewer side effects than monotherapy. Two Phase 2 studies comparing combination therapy that included an antimuscarinic demonstrated improvement in mean voided volume, the primary outcome chosen, with some combinations showing improved micturition frequency and quality of life. The two studies found no evidence of an increased safety risk with combination therapy compared to monotherapy. Future studies should use clinically meaningful or patient reported outcomes such as incontinence episodes when comparing efficacy. If surrogate measures are used, a clear justification should be provided. Cost analyses should be planned for clinical research trials evaluating combination drug therapy. Combination therapy is reasonable when monotherapy has suboptimal efficacy or bothersome side effects. Future research studies evaluating combination therapy for urgency urinary incontinence should ideally(1) be performed as part of a randomized clinical trial,(2) evaluate non-responders to monotherapy,(3) evaluate combination therapy using medications with different mechanisms of action,(4) include clinically meaningful and patient reported outcomes when evaluating efficacy, and(5) include cost-effectiveness analyses to justify any increased cost by showing improvement in efficacy or reduction in side effects. © 2016 Wiley Periodicals, Inc.

Secondary prevention medications reduce risk of stroke recurrence, yet many people do not receive recommended treatment, nor take medications optimally. Exploring how patients report making use of practitioners' advice on secondary prevention medicines on an online forum and what feedback was received from other participants. Thematic analysis of the archive of Talkstroke (2004-2011), UK. Posts including any secondary prevention medication terms, General Practitioner (GP) and their replies were identified. Fifity participants talked about practitioners' advice on secondary prevention medications in 43 discussion threads. Patients consulted practitioners for reassurance and dealing with side effects. Practitioners' advice varied from altering to maintaining current treatment. Three main themes emerged from the use of practitioners' advice: patients following advice (reassured, happy when side effects made tolerable, or still retaining anxiety about treatment); patients not following advice (admitting adherence on-off or stopping medications as side effects still not tolerable); asking other participants for feedback on advice received. Practitioners' advice was disregarded mainly when related to dealing with statin side effects, after one or two consultations. Themes for feedback involved sharing experience, directing back to practitioners, or to external evidence. Side effects of secondary prevention medications and statins in particular, cause anxiety and resentment in some patients, and their concerns are not always addressed by practitioners. Practitioners could consider more proactive strategies to manage such side effects. Forum feedback was appropriate and supportive of the practitioners' advice received. Our findings from peer-to-peer online conversations confirm and widen previous research. © The Author 2017. Published by Oxford University Press.

Severe valproate induced hyperammonemic encephalopathy successfully managed with peritoneal dialysis.

Kumar, Amandeep; Suri, Ashish; Sharma, Bhawani S

2014-07-01

Valproic acid (VPA) is a commonly used drug for epilepsy, psychiatric disorders and migraine and is frequently used in neurosurgical intensive care units. Though most of its side-effects are mild and transient, certain idiosyncratic side-effects have been attributed to VPA. Valproate induced hyperammonemia (VIH) is one such side-effect. VIH can produce symptoms of encephalopathy known as valproate induced hyperammonemic encephalopathy (VHE). VIH and VHE usually respond to withdrawal of VPA. However, in some cases VHE can be unresponsive to supportive measures and severe enough to be life-threatening. In such cases, dialysis can be used to rapidly reverse hyperammonemia and VHE and can prove to be a lifesaving measure. We report such a case of VIH and life-threatening VHE in a postoperative neurosurgical patient that was managed successfully with peritoneal dialysis.

Metronidazole is a commonly used antimicrobial worldwide. The most common side effects that have been reported are nausea, vomiting and hypersensitivity reactions. However, neurotoxicity has been reported with the use of metronidazole but rather rare. The most common neurological manifestation is peripheral neuropathy involvement in the form of sensory loss. It is worth mentioning that central neurotoxicity is a rare side effect of metronidazole use but reversible. The manifestations vary from a headache, altered mental status to focal neurological deficits. The diagnosis is mainly by neuroimaging in the setting of acute neurological change in the patient status. Here, we report a case of metronidazole-induced neurotoxicity in a 38-year-old male patient who was admitted with a brain abscess and was started on metronidazole for more than 10 weeks. © BMJ Publishing Group Ltd (unless otherwise stated in the text of the article) 2018.

2018-01-01

　During the preclinical research period of drug development, animal testing is widely used to help screen out a drug's dangerous side effects. However, it remains difficult to predict side effects within the central nervous system. Here, we introduce a machine learning-based in vitro system designed to detect seizure-inducing side effects before clinical trial. We recorded local field potentials from the CA1 alveus in acute mouse neocortico-hippocampal slices that were bath-perfused with each of 14 different drugs, and at 5 different concentrations of each drug. For each of these experimental conditions, we collected seizure-like neuronal activity and merged their waveforms as one graphic image, which was further converted into a feature vector using Caffe, an open framework for deep learning. In the space of the first two principal components, the support vector machine completely separated the vectors (i.e., doses of individual drugs) that induced seizure-like events, and identified diphenhydramine, enoxacin, strychnine and theophylline as "seizure-inducing" drugs, which have indeed been reported to induce seizures in clinical situations. Thus, this artificial intelligence-based classification may provide a new platform to pre-clinically detect seizure-inducing side effects of drugs.

Various biological factors have been implicated in convulsive seizures, involving side effects of drugs. For the preclinical safety assessment of drug development, it is difficult to predict seizure-inducing side effects. Here, we introduced a machine learning-based in vitro system designed to detect seizure-inducing side effects. We recorded local field potentials from the CA1 alveus in acute mouse neocortico-hippocampal slices, while 14 drugs were bath-perfused at 5 different concentrations each. For each experimental condition, we collected seizure-like neuronal activity and merged their waveforms as one graphic image, which was further converted into a feature vector using Caffe, an open framework for deep learning. In the space of the first two principal components, the support vector machine completely separated the vectors (i.e., doses of individual drugs) that induced seizure-like events and identified diphenhydramine, enoxacin, strychnine and theophylline as "seizure-inducing" drugs, which indeed were reported to induce seizures in clinical situations. Thus, this artificial intelligence-based classification may provide a new platform to detect the seizure-inducing side effects of preclinical drugs. Copyright © 2017 The Authors.

We describe a 60-year-old woman with active rheumatoid arthritis (RA) and endstage renal disease secondary to hypertensive nephrosclerosis undergoing hemodialysis. She had tried multiple antirheumatic medications; however, their usefulness was limited due to toxic side effects or lack of efficacy. She was then treated with chimeric antitumor necrosis factor monoclonal antibody (infliximab), which resulted in immediate improvement in clinical and laboratory measures. After about 2 years of therapy, no side effects have been observed. This report expands the spectrum of infliximab to include RA patients with renal insufficiency.

Immunomodulatory drugs (IMiDs) currently used in the treatment of multiple myeloma, are thalidomide, lenalidomide and pomalidomide. One of the most common side effects of thalidomide is neurotoxicity, predominantly in the form of peripheral neuropathy. We report 6 cases of significant central neurotoxicity associated with IMiD therapy. Treatment with thalidomide (1 patient), lenalidomide (4 patients), and pomalidomide (1 patient) was associated with various clinical manifestations of central neurotoxicity, including reversible coma, amnesia, expressive aphasia, and dysarthria. Central neurotoxicity should be recognized as an important side effect of IMiD therapy.

An adverse toxic reaction to the topical application of a 2% boric acid solution is described in a 2-year-old girl. Topical boric acid is licensed for use in children above the age of 10 in the Czech Republic. However, it can be bought over the counter and it is very often used in younger children. Due to its fast absorption and slow elimination, there is a high risk of systemic side effects. On the other hand, topical side effects are not reported in the present literature. © 2014 Wiley Periodicals, Inc.

Pain therapy with oxycodone/naloxone prolonged-release combination: case report

PubMed Central

Droń, Aleksandra

2013-01-01

Pain afflicts patients suffering from many chronic diseases and is present in 80% of cases of patients with advanced cancer who suffer from persistent pain. The aim of the pain treatment is to achieve the maximum analgesic effect while minimizing side effects. The main analgesic agent – morphine is unfortunately a therapy associated with gastrointestinal side effects. It appears that the combination of oxycodone and naloxone available as Targin® (Mundipharma) is an alternative. The paper presents a case of a 45-year-old patient who was treated effectively with oxycodone/naloxone prolonged-release tablets. This treatment has proven to be effective in providing pain and constipation control. PMID:24592131

The purpose of the study was to better understand why patients with history of head and neck cancer (HNC) treated with radiotherapy are using medical marijuana (MM). Established HNC quality of life questionnaires and our own MM quality of life questionnaire were sent to 15 HNC patients treated at our institution who reported using MM. Patients are clinically disease free and currently using MM to manage long-term side effects after curative HNC treatment. There was a 100 % response rate. Median time from treatment was 45 months (21-136 months). Most patients smoked marijuana (12 patients), while others reported ingestion (4 patients), vaporizing (3 patients), and use of homemade concentrated oil (1 patient). Six patients reported prior recreational marijuana use before diagnosis. MM provided benefit in altered sense, weight maintenance, depression, pain, appetite, dysphagia, xerostomia, muscle spasm, and sticky saliva. HNC patients report MM use to help with long-term side effects of radiotherapy.

A numerical study of some potential sources of error in side-by-side seismometer evaluations

USGS Publications Warehouse

Holcomb, L. Gary

1990-01-01

This report presents the results of a series of computer simulations of potential errors in test data, which might be obtained when conducting side-by-side comparisons of seismometers. These results can be used as guides in estimating potential sources and magnitudes of errors one might expect when analyzing real test data. First, the derivation of a direct method for calculating the noise levels of two sensors in a side-by-side evaluation is repeated and extended slightly herein. This bulk of this derivation was presented previously (see Holcomb 1989); it is repeated here for easy reference.This method is applied to the analysis of a simulated test of two sensors in a side-by-side test in which the outputs of both sensors consist of white noise spectra with known signal-tonoise ratios (SNR's). This report extends this analysis to high SNR's to determine the limitations of the direct method for calculating the noise levels at signal-to-noise levels which are much higher than presented previously (see Holcomb 1989). Next, the method is used to analyze a simulated test of two sensors in a side-by-side test in which the outputs of both sensors consist of bandshaped noise spectra with known signal-tonoise ratios. This is a much more realistic representation of real world data because the earth's background spectrum is certainly not flat.Finally, the results of the analysis of simulated white and bandshaped side-by-side test data are used to assist in interpreting the analysis of the effects of simulated azimuthal misalignment in side-by-side sensor evaluations. A thorough understanding of azimuthal misalignment errors is important because of the physical impossibility of perfectly aligning two sensors in a real world situation. The analysis herein indicates that alignment errors place lower limits on the levels of system noise which can be resolved in a side-by-side measurement It also indicates that alignment errors are the source of the fact that real data noise spectra tend to follow the earth's background spectra in shape.

Radioactive 131I is currently reported to be a potential effective intervention for Graves' Disease treatment in China. Whether 131I treatment was associated with effective outcome or reduced risk of side effects, reccurence rate remained unknown. Eligible studies were selected from Chinese VIP, Wangfang, CNKI databases using the keywords "Iodine" and "Graves Disease". Finally, 13 clinical trials met the inclusion criterion and were included this meta-analysis. Our meta-analysis included 1355 patients diagnosed of Graves' Disease with regular anti-thyroid drugs oral administration and 1320 patients with 131I therapy. The results showed that there was significant symptom improvement with radioactive iodine intervention (Odd Ratio (OR)=4.50, 95% CI [3.55, 5.71], P<0.01). 3 studies mentioned side effects, 6 mentioned reccurence rate and another 6 mentioned hypothyroidism. The ORs and 95%CIs for these subgroups were 0.12 [0.06, 0.21], 0.08 [0.05, 0.13] and 2.27 [1.77, 2.92] respectively. It means a significant reduction of side effects and reccurence rate but increased hypothyroidism after 131I intervention in Graves' Disease. Treatment with 131I was associated with better clinical outcome; it reduced side effects and reccurence rate but increased hypothyroidism in Graves' Disease.

Continuous positive airway pressure (CPAP) is the treatment of choice for obstructive sleep apnoea syndrome (OSAS), but side effects are common and long-term adherence low. The Type D (distressed) personality is defined as a combination of negative affectivity and social inhibition. The association of Type D personality with adherence has not been studied in CPAP-treated patients with OSAS. This study aimed to describe the prevalence of Type D personality in OSAS patients with CPAP treatment longer than 6 months and the association with self-reported side effects and adherence. A cross-sectional descriptive design was used. A total of 247 OSAS patients with a mean use of CPAP treatment for 55 months (6-182 months) were included. Data collection was achieved by two questionnaires; the Type D scale 14 (DS14) (Type D personality), SECI (side effects of CPAP), as well as from medical records (clinical variables and objective adherence to CPAP treatment). Type D personality occurred in 30% of the patients with OSAS and significantly (P < 0.05-0.001) increased the perceived frequency and severity of a broad range of side effects. The objective adherence was significantly lower (P < 0.001) for OSAS patients with Type D compared to OSAS patients without Type D, both with regard to a mean use of 4 h per night and 85% of the self-rated sleep time per night. The additional effect of a Type D personality on perceived side effects and adherence to CPAP treatment found in this study could be used by healthcare personnel when evaluating patients waiting for treatment.

The evil of the unknown--risk-benefit evaluation of new synthetic drugs in the 19th century.

PubMed

Schneider, A; Helmstädter, A

2015-01-01

In the 19th century, synthetic chemistry discovered completely new chemical entities for medicinal use, which dramatically enriched the therapeutic armamentarium. However, no information was available regarding the safety of these new drugs, which were unrelated to most of the medicinal agents formerly known. Therefore, the question arises, if and how far, considerations regarding the relationship between benefit and risks were made. In this study, chloroform, phenazone (antipyrine) and sulfonal, were investigated as examples for drugs newly introduced in the 19th century. The results revealed that these drugs were provided by the manufacturer, tested by the physicians in a multicentre pattern and side effects were published in the medical literature soon after. Within a few years, several hundred cases were reported but the data were rarely summarized statistically. Therefore, physicians needed to stay updated with the medical literature because neither systematic industrial research nor regulatory authorities existed. The number of case reports within the first years were sufficient to detect common (> 1/100 to < 1/10) side effects but rare events were also reported. An extraordinary example is the drug-induced toxic epidermal necrolysis, which is commonly known as the Lyell syndrome or its less severe form, the Stevens-Johnson syndrome. This reaction has been clearly described by Baruch Spitz (1854-1932) as a side effect of antipyrine in 1887, several decades before Stevens, Johnson and particularly Lyell.

To evaluate the efficacy and safety of disulfiram for treatment of binge eating disorder. Two hundred and fifty milligrams per day of disulfiram was administered to 12 patients affected by binge eating disorder for 16 weeks; the number of binge eating episodes per week and the number of participants who reported side effects were evaluated. Nine participants (75.0%) completed the trial, while the other 3 (25.0%) discontinued prematurely. Disulfiram significantly decreased the mean frequency of binge eating episodes per week from 7.9±1.2 to 0.9±0.6 (p<.001). All patients (100.0%) reduced the frequency of binge eating episodes, and 7 participants (58.3%) achieved remission of binge eating. Eleven participants (91.7%) reported side effects [drowsiness (N=9), headache (N=7), dysgeusia (N=3), tachycardia (N=3), dizziness (N=2), and nausea (N=2)]. While disulfiram reduced the frequency of binge eating episodes, side effects were observed in the majority of participants. Longer-term placebo-controlled studies are warranted to exclude the contribution of a placebo response from these results and to evaluate drugs with similar pharmacological activity but improved tolerability.

2000-02-01

We report a case of fatal hypermagnesemia resulting from the unsupervised use of high doses of magnesium oxide administered as part of a regimen of megavitamin and megamineral therapy to a child with mental retardation, spastic quadriplegia, and seizures. The treatment regimen was given at the recommendation of a dietician working as a private nutritional consultant without the involvement or notification of the child's pediatrician. Hypermagnesemia is an uncommon but serious side effect of the use of magnesium containing compounds. These compounds are widely used as laxatives and dietary supplements, and serious side effects are uncommon when used in appropriate dosages and with adequate supervision. The use of alternative medical therapies, including megavitamin/megamineral therapy, is widespread. Many patients use alternative medicine or seek care from alternative medicine practitioners without the recommendation or knowledge of their primary physicians. Despite unproved benefit, many alternative therapies may be safe. However, unsupervised use of generally safe treatments can result in serious side effects. This case report serves to illustrate the characteristic pathophysiologic changes of severe hypermagnesemia, an entity rarely seen in pediatric practice, and more importantly, it alerts primary care and subspecialty pediatricians to be aware of and monitor the use of alternative medical therapies in their patients.

Transcranial direct current stimulation is a noninvasive brain stimulation technique that has been studied for the treatment of neuropsychiatric disorders in adults, with minimal side effects. The objective of this study is to report the feasibility, tolerability, and the short-term adverse effects of transcranial direct current stimulation in children from 5 to 12 years of age. It is a naturalistic study of 14 children who underwent 10 sessions of transcranial direct current stimulation as an alternative, off-label, and open-label treatment for various languages disorders. Frequency, intensity, adverse effects, and perception of improvement reported by parents were collected. The main side effects detected were tingling (28.6%) and itching (28.6%), acute mood changes (42.9%), and irritability (35.7%). Transcranial direct current stimulation is a feasible and tolerable technique in children, although studies regarding plastic and cognitive changes in children are needed to confirm its safety. In conclusion, this is a naturalistic report in which we considered transcranial direct current stimulation as feasible in children. © The Author(s) 2013.

Transcutaneous intense focused ultrasound is a novel Food and Drug Administration-approved technology for noninvasive skin tightening of the face and neck. No studies have reported on its safety and effectiveness on nonfacial areas. Eighteen paired areas (6 each) on the upper arms, medial thighs, and extensor knees were randomly treated with two different transducers (4.0 MHz, 4.5-mm focal depth and 7.0 MHz, 3.0-mm focal depth). One side was randomly assigned to receive a single pass (single plane) of microthermal coagulation zones over the involved area with the 4.0 MHz, 4.5-mm-depth transducer, and the contralateral side was assigned to receive consecutive single passes (dual plane) using both transducers (4.0 MHz, 4.5-mm depth followed by 7.0 MHz, 3.0-mm depth). Two independent masked assessors determined clinical improvement scores using comparative standardized photographs obtained at baseline and 3 and 6 months after treatment. Subjective assessments of clinical improvement and side effects of treatment were obtained. Global assessment scores revealed significant improvement in all treated areas, with the upper arms and knees demonstrating more skin lifting and tightening than the thighs. Areas receiving dual-plane treatment had slightly better clinical scores than those receiving single-plane treatment in all three sites. Clinical scores from single-plane and dual-plane treated areas continued to improve between 3 and 6 months after treatment. Side effects were mild and transient and included erythema, warmth, and skin tenderness. Rare focal bruising was noted in two patients on the upper arms that resolved within 7 days. No other side effects were reported or observed. Transcutaneous intense focused ultrasound can be safely and effectively used to improve the clinical appearance (texture and contour) of the upper arms, extensor knees, and medial thighs. © 2012 by the American Society for Dermatologic Surgery, Inc.

Electroconvulsive therapy (ECT) is a highly effective treatment for depression but its use is limited by the risk of cognitive side effects. This study explored the potential of a novel approach, ultrabrief pulsewidth (0.3 ms) right unilateral (RUL-UB) ECT, to minimise cognitive effects while preserving efficacy. Mood and neuropsychological functioning were objectively rated in 30 patients over a course of RUL-UB ECT at 6 times seizure threshold. Results (mood outcomes, ECT treatment parameters) were compared with a retrospectively assessed group of 30 age and gender matched patients who received RUL ECT (1.0 ms pulsewidth, 3.5 times seizure threshold) at the same hospital. Six treatments of RUL-UB ECT resulted in relatively few cognitive side effects, compared to reports of previous studies. The number of responders did not differ between groups but significantly more treatments were required in the RUL-UB group, suggesting a slower speed of response. Patients were not randomised to the two forms of ECT and data was obtained retrospectively in the RUL ECT comparison group. This study suggests that RUL-UB ECT can be effective in treating depression while incurring lesser cognitive side effects than a commonly used form of RUL ECT, but a greater number of treatments may be required for response.

To compare the maternal and fetal side effects of transdermal nitroglycerin and intravenous fenoterol combined with magnesium sulfate in a prospective randomised study. Fifty pregnant women between 27 and 35 weeks of gestation with preterm labour were treated with either nitroglycerin (0.4-0.8 mg/h) or fenoterol (60 - 120 microg/h). Outcome parameters were (1) the effects on fetal and maternal heart frequency (FHF/MHF) and blood pressure, and (2) subjective experiences of adverse effects assessed by utilising a questionnaire. In the fenoterol group, elevated mean MHF, FHF and systolic blood pressure were recorded compared to nitroglycerin. Fewer maternal side effects were reported in the nitroglycerin group. Palpitations (82%), tremor (68%) and restlessness (64%) were most common in the fenoterol group (two drop-outs), whereas nitroglycerin caused headaches in 71% of the cases (four drop-outs). Transdermal nitroglycerin appears to be a safe therapy for the mother and fetus and is a promising new option for the treatment of preterm labour.

Fluid loading with salt and water is a countermeasure used after space flight to restore body fluids. However, gastrointestinal side effects have been frequently reported in persons taking similar quantities of salt and water in ground-based studies. The effectiveness of the Shuttle fluid-loading countermeasure (8 gms salt, 0.97 liters of water) was compared to Astro-ade (an isotonic electrolyte solution), to maintain plasma volume (PV) during 4.5 hrs of resting fluid restriction. Three groups of healthy men (n=6) were studied: a Control Group (no drinking), an Astro-ade Group, and a Salt Tablet Group. Changes in PV after drinking were calculated from hematocrit and hemoglobin values. Both the Salt Tablet and Astro-ade Groups maintained PV at 2-3 hours after ingestion compared to the Control Group, which had a 6 percent decline. Side effects (thirst, stomach cramping, and diarrhea) were noted in at least one subject in both the Astro-ade and Salt Tablet Groups. Nausea and vomiting were reported in one subject in the Salt Tablet Group. It was concluded that Astro-ade may be offered as an alternate fluid-loading countermeasure but further work is needed to develop a solution that is more palatable and has fewer side effects.

Children with cerebral palsy (CP) are routinely treated with botulinum toxin A (BoNT-A). Two non dose-equivalent and differently priced products, Botox and Dysport are used. Depending on the conversion one of the products is considerably cheaper. However, the dose conversion factors studied to date have varied widely and relevant studies have not included children. Our objective here was to compare the efficacy and health economics of the switch from Botox to Dysport in children with CP when conversion was set to 1:2. Specifically were these treatments perceived as equivalent in terms of efficacy, duration and side-effects and were the drug cost lowered by using Dysport. This prospective, real-world, cost-effectiveness population-based observational study included all children with CP, (n = 159) mean age 9.4 years (SD, 4.3), in the larger Stockholm area who received BoNT-A between September 1, 2014, and December 31, 2015. Parents reported the efficacy, duration and side-effects of previous treatment while physicians reported doses and goals set by children and parents for the present treatment. Drug acquisition costs were provided by county administrators. In connection with 341 visits caregivers reported comparable effects of similar duration with these products, with few, similar and transient side-effects. The drug-cost per treatment was 4029 SEK for Botox and 2380 SEK in the case of Dysport. When Botox was replaced by a two-fold higher Unit dose of Dysport (conversion 1:2) parents perceived the treatment of their children with CP to be equally effective while the cost was 41% lower according to procured prices.

Laser treatment is a widespread method for hair removal. Despite its very common use, side effects remain relatively rare and transient. Axillary hyperhidrosis and bromhidrosis have already been reported in the literature after depilatory lasers. We report here a novel side effect of total body bromhidrosis following hair removal laser. A 27-year-old man, phototype 3 underwent four sessions of total body depilatory laser, combining pulsed alexandrite and pulsed diode lasers. A few days afterwards, a generalized foul odor was noted and was resistant to regular deodorants and Aluminum chloride based antiperspirants. Possible mechanisms include the activation of dormant bacteria in the skin flora, sweat gland dysfunction, altered skin flora, sweat gland hormone receptor disturbances, and genetic factors. Total body bromhidrosis and hyperhidrosis are potential complications of total body laser hair removal.

"Herbal seizures"--atypical symptoms after ibogaine intoxication: a case report.

Misuse of various new psychotropic substances such as ibogaine is increasing rapidly. Knowledge of their negative side effects is sparse. We present a case of intoxication with the herbal substance ibogaine in a 22-year-old white man. After taking a cumulative dose of 38 g (taken in two doses), he developed visual memories, nausea and vomiting. He developed a generalized tonic-clonic seizure with additional grand mal seizures. He was treated with midazolam and levetiracetam. Extended drug screenings and computed tomography and magnetic resonance imaging findings were all negative. Knowledge of the side effects of ibogaine has mainly come from reports of cardiovascular complications; seizures are rarely mentioned and experimental findings are inconsistent. It seems that ibogaine acts like a proconvulsive drug at high doses.

Side effects of beta-blocker treatments as related to the central nervous system.

PubMed

Dahlöf, C; Dimenäs, E

During the last decade beta-adrenoceptor antagonists have become one of the first-line treatments for hypertension. Generally, they have been shown to be safe with a low frequency of serious side effects. However, minor subjective symptoms, usually considered to be CNS-related, have been reported for all beta-blockers used. Thus, all beta-blockers on the market seem to have a high benefit:risk ratio; independent of their physicochemical properties and pharmacodynamic profile, however, they seem to cause CNS-related side effects to about the same extent. These minor side effects, the mechanisms of which are unclear, consist of subtle effects on general well being, decreased initiative, a depressed frame of mind, and disturbed sleep. Generally, however, beta-blockers in therapeutic dosages do not affect the qualitative functions of the brain. The results so far available have been obtained primarily by using objective methods. Further comparison has now been initiated using documented subjective methods to investigate whether the objectively documented differences are of any clinical relevance to the patient's quality of life. Although it cannot be claimed with certainty, nonselective beta-blockers seem to cause CNS-related side effects to a greater extent than beta 1-selective blockers. Differences in the degree of hydrophilicity of the beta-blocker are apparently of no clinical relevance in this respect. Rather, the plasma concentration of the beta-blocking drug (degree of beta-blockade) seems to be the major determinant of whether or not CNS-related symptoms appear in susceptible patients.

Forty-seven climbers participated in a double-blind, randomized trial comparing acetazolamide 250 mg, dexamethasone 4 mg, and placebo every eight hours as prophylaxis for acute mountain sickness during rapid, active ascent of Mount Rainier (elevation 4,392 m). Forty-two subjects (89.4 percent) achieved the summit in an average of 34.5 hours after leaving sea level. At the summit or high point attained above base camp, the group taking dexamethasone reported less headache, tiredness, dizziness, nausea, clumsiness, and a greater sense of feeling refreshed (p less than or equal to 0.05). In addition, they reported fewer problems of runny nose and feeling cold, symptoms unrelated to acute mountain sickness. The acetazolamide group differed significantly (p less than or equal to 0.05) from other groups at low elevations (1,300 to 1,600 m), in that they experienced more feelings of nausea and tiredness, and they were less refreshed. These drug side effects probably obscured the previously established prophylactic effects of acetazolamide for acute mountain sickness. Separate analysis of an acetazolamide subgroup that did not experience side effects at low elevations revealed a prophylactic effect of acetazolamide similar in magnitude to the dexamethasone effect but lacking the euphoric effects of dexamethasone. This study demonstrates that prophylaxis with dexamethasone can reduce the symptoms associated with acute mountain sickness during active ascent and that acetazolamide can cause side effects that may limit its effectiveness as prophylaxis against the disease.

Second-generation tyrosine kinase inhibitors (TKI2) often induce molecular remission, and prolonged survival with a better tolerance in imatinib-resistant chronic myelogenous leukaemia (CML) patients. We report the case of a CML in first chronic phase who was diagnosed in August 2003 in a young 24 year-old Caucasian woman. Our patient received first imatinib and then dasatinib and nilotinib. Imatinib was well tolerated and she developed TTP/HUS on dasatinib without documented evolution of CML and finally obtained MR5.0 with nilotinib and without any side effect. This case also illustrates the absence of cross-resistance and side-effects between the different TKIs and the feasibility of kidney transplantation associated with a nilotinib treatment of CML allowing a continuing MR5.0 and no further side effects.

Patients diagnosed with multiple myeloma and metastatic breast, prostate and renal cancers have a better opportunity for longer survival due to a myriad of chemotherapies regimens that attempt to manage disease progression while decreasing treatment-related side effects. Osteonecrosis of the jaws (ONJ) is a known side effect of bisphosphonates and other anti-neoplastic drugs. This complication can lead to oncologic treatment interruptions as well as diminished quality of life. Most recommendations for treatment of ONJ are based on position papers and case reports, while evidence-based treatment paradigms are lacking. With cancer survivorship on the rise, long-term chemotherapeutic side effects are becoming more prevalent and attention to untoward oral complications cannot be understated. In this review, the accepted recommendations for dental clearance prior to head and neck chemo-radiation therapy are put forth as a means of possibly preventing and treating drug induced ONJ.

Autoradiographic and biochemical observations on the distribution of non-steroid anti-inflammatory drugs.

PubMed

Rainsford, K D; Schweitzer, A; Brune, K

1981-04-01

A comparison has been made of the distribution of some new radioactively-labelled non-steroid anti-inflammatory (NSAI) drugs or pro-drugs with their respective progenitors and/or standard acidic NSAI drugs (i.e. aspirin, indomethacin and phenylbutazone), using whole body autoradiography and scintillation counting. The object of this study was to establish if the distribution of these new NSAI drugs may contribute to changes in their side-, or therapeutic effects compared with the older drugs. All the NSAI drugs accumulated in those tissues wherein the principle therapeutic and side-effects are manifest. The accumulation in inflamed tissues occurs regardless of the structural type of NSAI drugs, i.e. with specific accumulation occurring in this tissue of the acidic drugs or their acidic metabolites. New aspects of the distribution of the acetyl moiety of aspirin are reported which may be significant in relation to the side-effects induced by this drug.

Cardiac side effects of bruton tyrosine kinase (BTK) inhibitors.

PubMed

Tang, Chloe Pek Sang; McMullen, Julie; Tam, Constantine

2017-09-13

The development of bruton tyrosine kinase inhibitors (BTKi) has been a significant advancement in the treatment of chronic lymphocytic leukemia and related B-cell malignancies. As experience in using ibrutinib increased, the first drug to be licensed in its class, atrial fibrillation (AF) emerged as an important side effect. The intersection between BTKi therapy for B-cell malignancies and AF represents a complex area of management with scant evidence for guidance. Consideration needs to be taken regarding the interplay of increased bleeding risk versus thromboembolic complications of AF, drug interactions between ibrutinib and anticoagulants and antiarrhythmic agents, and the potential for other, as yet seldom reported cardiac side effects. This review describes the current knowledge regarding BTKi and potential pathophysiologic mechanisms of AF and discusses the management of BTKi-associated AF. Finally, a review of the second generation BTKi is provided and gaps in knowledge in this evolving field are highlighted.

Experiences With a Self-Reported Mobile Phone-Based System Among Patients With Colorectal Cancer: A Qualitative Study.

2016-06-09

In cancer care, mobile phone-based systems are becoming more widely used in the assessment, monitoring, and management of side effects. To explore the experiences of patients with colorectal cancer on using a mobile phone-based system for reporting neurotoxic side effects. Eleven patients were interviewed (ages 44-68 years). A semistructured interview guide was used to perform telephone interviews. The interviews were transcribed verbatim and analyzed with qualitative content analysis. The patients' experiences of using a mobile phone-based system were identified and constructed as: "being involved," "pacing oneself," and "managing the questions." "Being involved" refers to their individual feelings. Patients were participating in their own care by being observant of the side effects they were experiencing. They were aware that the answers they gave were monitored in real time and taken into account by health care professionals when planning further treatment. "Pacing oneself" describes how the patients can have an impact on the time and place they choose to answer the questions. Answering the questionnaire was easy, and despite the substantial number of questions, it was quickly completed. "Managing the questions" pointed out that the patients needed to be observant because of the construction of the questions. They could not routinely answer all the questions. Patients understood that side effects can vary during the cycles of treatment and need to be assessed repeatedly during treatment. This mobile phone-based system reinforced the patients' feeling of involvement in their own care. The patients were comfortable with the technology and appreciated that the system was not time consuming.

Adherence to treatment is a complex and poorly understood phenomenon. This study investigates the relationship between older depressed patients' adherence to antidepressants and their beliefs about and knowledge of the medication. Assessment was undertaken of 108 outpatients over the age of 55 years diagnosed with depressive disorder and treated for at least four weeks with antidepressants. Adherence was assessed using two self-report measures: the Medication Adherence Rating Scale (MARS) and a Global Adherence Measure (GAM). Potential predictors of adherence investigated included sociodemographic, medication and illness variables. In addition, 33 carers were interviewed regarding general medication beliefs. 56% of patients reported 80% or higher adherence on the GAM. Sociodemographic variables were not associated with adherence on the MARS. Specific beliefs about medicines, such as "my health depends on antidepressants" (necessity) and being less worried about becoming dependant on antidepressants (concern) were highly correlated with adherence. General beliefs about medicines causing harm or being overprescribed, experiencing medication side-effects and severity of depression also correlated with poor adherence. Linear regression with the MARS as the dependent variable explained 44.3% of the variance and showed adherence to be higher in subjects with healthy specific beliefs who received more information about antidepressants and worse with depression severity and autonomic side-effects. Our findings strongly support a role for specific beliefs about medicines in adherence. Challenging patients' beliefs, providing information about treatment and discussing side-effects could improve adherence. Poor response to treatment and medication side-effects can indicate poor adherence and should be considered before switching medications.

Nanoformulated water-soluble paclitaxel to enhance drug efficacy and reduce hemolysis side effect.

Surgery, chemotherapy, and radiotherapy are the three top cancer treatment modalities. Paclitaxel (PTX) is one of the most widely used chemotherapy drugs. However, its clinical applications have been significantly limited due to: (i) serious hemolysis effect of currently available commercial paclitaxel formulations and (ii) its water insolubility. An easy way to deliver paclitaxel by a new nanocarrier system using pluronic copolymers of P123/F68 and Sorbitan monopalmitate (Span 40) was reported in our previous research article. The characterization of the formulation and analysis of drug release and cellular uptake were also presented. In this article, we reported discoveries of our follow-up in vivo antitumor and in vitro hemolytic study discoveries. The experimental results showed that the nanoformulated PTX achieved much better tumor suppression performance while reducing hemolysis side effects. This newly formulated drug can significantly improve patient outcomes in cancer chemotherapy.

In Japan, the human papillomavirus (HPV) vaccination rate has sharply fallen to nearly 0% due to sensational media reports of adverse events. Online anti-HPV-vaccination activists often warn readers of the vaccine's dangers. Here, we aimed to examine frequently appearing contents on pro- and anti-HPV vaccination websites. We conducted online searches via two major search engines (Google Japan and Yahoo! Japan). Targeted websites were classified as "pro," "anti," or "neutral" according to their claims, with the author(s) classified as "health professionals," "mass media," or "laypersons." We then conducted a text mining analysis. Of the 270 sites analyzed, 16 contents were identified. The most frequently appearing contents on pro websites were vaccine side effects, preventable effect of vaccination, and cause of cervical cancer. The most frequently appearing contents on anti websites were vaccine side effects, vaccine toxicity, and girls who suffer from vaccine side effects. Main disseminators of each content according to the author's expertise were also revealed. Pro-HPV vaccination websites should supplement deficient contents and respond to frequent contents on anti-HPV websites. Effective tactics are needed to better communicate susceptibility to cervical cancer, frequency of side effects, and responses to vaccine toxicity and conspiracy theories.

Treatment of pediatric acute lymphoblastic leukemia (ALL) relies on systemic corticosteroids for remission; however, they can cause significant mood and behavior changes that interfere with quality of life and may increase risk for injury. This case series reports on preschool children with preexisting developmental and psychiatric risk factors who presented with behavioral side effects that required intervention. Identification of these vulnerable children may provide opportunities for early intervention, anticipatory guidance, and effective treatment to minimize behavioral side effects and improve quality of life and safety during ALL treatment. © 2016 Wiley Periodicals, Inc.

Opioid Receptors: Toward Separation of Analgesic from Undesirable Effects

2013-01-01

The use of opioid analgesics for pain has always been hampered by their many side effects; in particular, the addictive liability associated with chronic use. Recently, attempts to develop analgesic agents with reduced side effects have targeted either the putative opioid receptor splice variants or the receptor heterooligomers. This review discusses the potential for receptor splice variant- and the hetero-oligomer-based discovery of new opioid analgesics. We also examine an alternative approach of using receptor mutants for pain management. Finally, we discuss the role of the biased agonism observed and the recently reported opioid receptor crystal structures in guiding the future development of opioid analgesics PMID:23598157

2010-01-01

In this study, we evaluated subjective nighttime discomfort-glare responses on three different types of planar and non-planar driver-side mirrors on two age groups. Fifty-six individuals (28 young [18–35 years] and 28 old [65 years and over]) participated in this experiment. Subjective discomfort-glare rating scores on three different types of driver-side mirrors were assessed utilizing De Boer's rating scale in a controlled nighttime driving environment (laboratory ambient illuminant level—l lux with headlight turned off). Three driver-side mirrors included planar “flat mirror”: radius of curvature 242650.92 mm, reflectivity 0.60114, and surface reflectance 0.60568; “curved mirror”: radius of curvature 1433.3 mm, reflectivity 0.21652, and surface reflectance 0.58092; “blue mirror”: radius of curvature 1957.1 mm, reflectivity 0.25356, and surface reflectance 0.54585. The results indicated that with the same glare level (as measured by angle of incidence and illuminance in front of the eyes), older adults reported worse feelings of glare than their younger counterparts. Furthermore, the results indicated that both young and older adults reported worse feelings of glare for planar driver-side mirror than non-planar driver-side mirrors. These results suggest that older adults' criterion of discomfort-glare is more sensitive than their younger counterparts, and importantly, the non-planar driver-side mirrors can be beneficial in terms of reducing nighttime discomfort-glare for both the young and the elderly.

Commercial Online Social Network Data and Statin Side-Effect Surveillance: A Pilot Observational Study of Aggregate Mentions on Facebook.

2017-12-01

Surveillance of the safety of prescribed drugs after marketing approval has been secured remains fraught with complications. Formal ascertainment by providers and reporting to adverse-event registries, formal surveys by manufacturers, and mining of electronic medical records are all well-known approaches with varying degrees of difficulty, cost, and success. Novel approaches may be a useful adjunct, especially approaches that mine or sample internet-based methods such as online social networks. A novel commercial software-as-a-service data-mining product supplied by Sysomos from Datasift/Facebook was used to mine all mentions on Facebook of statins and stain-related side effects in the US in the 1-month period 9 January 2017 through 8 February 2017. A total of 4.3% of all 25,700 mentions of statins also mentioned typical stain-related side effects. Multiple methodological weaknesses stymie interpretation of this percentage, which is however not inconsistent with estimates that 5-20% of patients taking statins will experience typical side effects at some time. Future work on pharmacovigilance may be informed by this novel commercial tool, but the inability to mine the full text of a posting poses serious challenges to content categorization.

Objective Abortion either medical or criminal has distinctive physical, social, and psychological side effects. Detecting types and frequent psychological side effects of abortion among post abortion care seeking women in Tehran was the main objective of the present study. Method 278 women of reproductive age (15-49) interviewed as study population. Response rate was 93/8. Data collected through a questionnaire with 2 parts meeting broad socio-economic characteristics of the respondents and health- related abortion consequences. Tehran hospitals were the site of study. Results The results revealed that at least one-third of the respondents have experienced psychological side effects. Depression, worrying about not being able to conceive again and abnormal eating behaviors were reported as dominant psychological consequences of abortion among the respondents. Decreased self-esteem, nightmare, guilt, and regret with 43.7%, 39.5%, 37.5%, and 33.3% prevalence rates have been placed in the lower status, respectively. Conclusion Psychological consequences of abortion have considerably been neglected. Several barriers made findings limited. Different types of psychological side effects, however, experienced by the study population require more intensive attention because of chronic characteristic of psychological disorders, and women's health impact on family and population health.

To describe attitudes and experiences with a low-dose oral contraceptive pill (Alesse) over 3 months, women aged 18 years and older (n = 218) were enrolled from 16 locations to evaluate their experiences with Alesse. The questionnaire assessed demographic and personal characteristics, attitudes and experiences, and satisfaction. The participants had a mean age of 26.7 years and most were single, Caucasian, had completed high school, had a regular sexual partner, and had previously used OCs. Sixty percent of participants could discuss pill use easily with their mothers, 92% with friends, and 96% with partners; 45% of the women were unsure about their mother's previous OC use. Of the 11 side effects assessed, the most frequently anticipated side effect was weight gain. There was a significant relationship between anticipated and reported side effects for weight and mood changes; however, there remained a number of women for whom these differed. Most (90%) were satisfied with Alesse. Even when beginning on 20 microg pills, some women may still anticipate side effects such as weight gain typically associated with higher doses of estrogen. Healthcare providers should assess women's attitudes and anticipated experiences with OCs and counsel accordingly.

Medical Cannabis Use Is Associated With Decreased Opiate Medication Use in a Retrospective Cross-Sectional Survey of Patients With Chronic Pain.

Boehnke, Kevin F; Litinas, Evangelos; Clauw, Daniel J

2016-06-01

Opioids are commonly used to treat patients with chronic pain (CP), though there is little evidence that they are effective for long term CP treatment. Previous studies reported strong associations between passage of medical cannabis laws and decrease in opioid overdose statewide. Our aim was to examine whether using medical cannabis for CP changed individual patterns of opioid use. Using an online questionnaire, we conducted a cross-sectional retrospective survey of 244 medical cannabis patients with CP who patronized a medical cannabis dispensary in Michigan between November 2013 and February 2015. Data collected included demographic information, changes in opioid use, quality of life, medication classes used, and medication side effects before and after initiation of cannabis usage. Among study participants, medical cannabis use was associated with a 64% decrease in opioid use (n = 118), decreased number and side effects of medications, and an improved quality of life (45%). This study suggests that many CP patients are essentially substituting medical cannabis for opioids and other medications for CP treatment, and finding the benefit and side effect profile of cannabis to be greater than these other classes of medications. More research is needed to validate this finding. This article suggests that using medical cannabis for CP treatment may benefit some CP patients. The reported improvement in quality of life, better side effect profile, and decreased opioid use should be confirmed by rigorous, longitudinal studies that also assess how CP patients use medical cannabis for pain management.

Clinicians are incorporating patient-reported outcomes in the management of HIV-infected persons co-infected with hepatitis C virus (HCV), but there are no validated inventories to monitor symptoms of patients during HCV therapy. Five-year retrospective cohort analysis of persons living with HIV (PLWH) treated for HCV. The HCV symptom-inventory (HCV-SI) was administered before, during, and after HCV treatment. Discriminant validity was assessed, separately, in mixed model linear regression of HCV-SI T-scores on treatment regimens (pegylated-interferon and ribavirin; pegylated-interferon, ribavirin, and telaprevir; and interferon-free antivirals); and side effect-related premature treatment discontinuation (SE-DC). From the 103 patients who completed the HCV-SI, 7% were female, 26% non-white, 32% cirrhotics and 91% had undetectable HIV viral loads. Most had genotype 1 (83%) and were HCV treatment-naïve (78%). We treated 19% of patients with pegylated-interferon and ribavirin, 22% with pegylated-interferon, ribavirin, and telaprevir and 59% received interferon-free antivirals. Overall, 77% achieved a sustained virologic response, and 6% discontinued HCV treatment due to side effects. In the treatment discrimination model, compared to the no treatment period, HCV-SI scores were significantly (p < 0.01) lower for interferon-free antivirals and higher for interferon-containing regimens. In the SE-DC model, the total HCV-SI, somatic and neuropsychiatric scores significantly predicted those patients who prematurely discontinued HCV treatment (P < 0.05). The HCV-SI effectively differentiated among treatment regimens known to vary by side effect profiles and between patients with and without treatment discontinuation due to side effects. The HCV-SI may have value as a patient-reported outcome instrument predicting the risk of HCV treatment discontinuation.

Immunohistochemical Evaluation of Androgen Receptor and Nerve Structure Density in Human Prepuce from Patients with Persistent Sexual Side Effects after Finasteride Use for Androgenetic Alopecia

Finasteride is an inhibitor of 5-α-reductase used against male androgenetic alopecia (AGA). Reported side effects of finasteride comprise sexual dysfunction including erectile dysfunction, male infertility, and loss of libido. Recently these effects were described as persistent in some subjects. Molecular events inducing persistent adverse sexual symptoms are unexplored. This study was designed as a retrospective case-control study to assess if androgen receptor (AR) and nerve density in foreskin prepuce specimens were associated with persistent sexual side effects including loss of sensitivity in the genital area due to former finasteride use against AGA. Cases were 8 males (aged 29–43 years) reporting sexual side effects including loss of penis sensitivity over 6 months after discontinuation of finasteride who were interviewed and clinically visited. After informed consent they were invited to undergo a small excision of skin from prepuce. Controls were 11 otherwise healthy matched men (aged 23–49 years) who undergone circumcision for phimosis, and who never took finasteride or analogues. Differences in AR expression and nerve density in different portions of dermal prepuce were evaluated in the 2 groups. Density of nuclear AR in stromal and epithelial cells was higher in cases (mean 40.0%, and 80.6% of positive cells, respectively) than controls (mean 23.4%, and 65.0% of positive cells, respectively), P = 0.023 and P = 0.043, respectively. Conversely, percentage of vessel smooth muscle cells positive for AR and density of nerves were similar in the 2 groups. The ratio of AR positive stromal cells % to serum testosterone concentrations was 2-fold higher in cases than in controls (P = 0.001). Our findings revealed that modulation of local AR levels might be implicated in long-term side effects of finasteride use. This provides the first evidence of a molecular objective difference between patients with long-term adverse sexual effects after finasteride use versus drug untreated healthy controls in certain tissues.

Women commonly report changing contraceptive methods because of side-effects. However, there is a lack of literature that has thoroughly examined women's perspectives, including why they changed contraception. Using qualitative data from a contraceptive survey of young Australian women, we explored women's explanations for their recent changes in contraception. A thematic analysis of 1051 responses to a question about why women recently changed contraception was conducted. Themes reflected reasons for changing contraception which included: both contraceptive and non-contraceptive (4%); relationship/sexual (9%); medical (11%); contraceptive (18%); non-contraceptive (41%). A minority of responses were uncoded (17%). Non-contraceptive effects (effects unrelated to pregnancy prevention) featured most frequently in women's reasons for changing contraception. While cessation of various contraceptives due to unwanted side-effects is a well-known phenomenon, this analysis provides evidence of the changing of contraception for its non-contraceptive effects and reframes the notion of 'side-effects'.

Low contraceptive uptake and high unmet need for contraception remain significant issues in Uganda compared to neighboring countries such as Kenya, Ethiopia, and Rwanda. Although prior research on contraceptive uptake has indicated that male partners strongly influence women's decisions around contraceptive use, there is limited in-depth qualitative research on knowledge and concerns regarding modern contraceptive methods among Ugandan men. Using in-depth interviews (N = 41), this qualitative study investigated major sources of knowledge about contraception and perceptions of contraceptive side effects among married Ugandan men. Men primarily reported knowledge of contraceptives based on partner's experience of side effects, partner's knowledge from health providers and mass media campaigns, and partner's knowledge from her peers. Men were less likely to report contraceptive knowledge from health care providers, mass media campaigns, or peers. Men's concerns about various contraceptive methods were broadly associated with failure of the method to work properly, adverse health effects on women, and severe adverse health effects on children. Own or partner's human immunodeficiency virus (HIV) status did not impact on contraceptive knowledge. Overall, we found limited accurate knowledge about contraceptive methods among men in Uganda. Moreover, fears about the side effects of modern contraceptive methods appeared to be common among men. Family planning services in Uganda could be significantly strengthened by renewed efforts to focus on men's knowledge, fears, and misconceptions.

Right-sided infective endocarditis: recent epidemiologic changes

PubMed Central

Yuan, Shi-Min

2014-01-01

Background: Infective endocarditis (IE) has been increasingly reported, however, little is available regarding recent development of right-sided IE. Methods: Right-sided IE was comprehensively analyzed based on recent 5⅓-year literature. Results: Portal of entry, implanted foreign material, and repaired congenital heart defects were the main predisposing risk factors. Vegetation size on the right-sided valves was much smaller than those beyond the valves. Multiple logistic regression analysis revealed that predisposing risk factors, and vegetation size and locations were independent predictive risks of patients’ survival. Conclusions: Changes of right-sided IE in the past 5⅓ years included younger patient age, and increased vegetation size, but still prominent Staphylococcus aureus infections. Complication spectrum has changed into more valve insufficiency, more embolic events, reduced abscess formation, and considerably decreased valve perforations. With effective antibiotic regimens, prognoses of the patients seemed to be better than before. PMID:24482708

Transient Three-Dimensional Side Load Analysis of Out-of-Round Film Cooled Nozzles

Wang, Ten-See; Lin, Jeff; Ruf, Joe; Guidos, Mike

2010-01-01

The objective of this study is to investigate the effect of nozzle out-of-roundness on the transient startup side loads. The out-of-roundness could be the result of asymmetric loads induced by hardware attached to the nozzle, asymmetric internal stresses induced by previous tests and/or deformation, such as creep, from previous tests. The rocket engine studied encompasses a regeneratively cooled thrust chamber and a film cooled nozzle extension with film coolant distributed from a turbine exhaust manifold. The computational methodology is based on an unstructured-grid, pressure-based computational fluid dynamics formulation, and a transient inlet history based on an engine system simulation. Transient startup computations were performed with the out-of-roundness achieved by four degrees of ovalization of the nozzle: one perfectly round, one slightly out-of-round, one more out-of-round, and one significantly out-of-round. The computed side load physics caused by the nozzle out-of-roundness and its effect on nozzle side load are reported and discussed.

To systematically investigate the literature for the influence of sublingual nitroglycerin administration on coronary diameter, the number of evaluable segments, image quality, heart rate and blood pressure, and diagnostic accuracy of coronary computed tomography (CT) angiography. A systematic search was performed in PubMed, EMBASE and Web of Science. The studies were evaluated for the effect of sublingual nitroglycerin on coronary artery diameter, evaluable segments, objective and subjective image quality, systemic physiological effects and diagnostic accuracy. Due to the heterogeneous reporting of outcome measures, a narrative synthesis was applied. Of the 217 studies identified, nine met the inclusion criteria: seven reported on the effect of nitroglycerin on coronary artery diameter, six on evaluable segments, four on image quality, five on systemic physiological effects and two on diagnostic accuracy. Sublingual nitroglycerin administration resulted in an improved evaluation of more coronary segments, in particular, in smaller coronary branches, better image quality and improved diagnostic accuracy. Side effects were mild and were alleviated without medical intervention. Sublingual nitroglycerin improves the coronary diameter, the number of assessable segments, image quality and diagnostic accuracy of coronary CT angiography without major side effects or systemic physiological changes. • Sublingual nitroglycerin administration results in significant coronary artery dilatation. • Nitroglycerin increases the number of evaluable coronary branches. • Image quality is improved the most in smaller coronary branches. • Nitroglycerin increases the diagnostic accuracy of coronary CT angiography. • Most side effects are mild and do not require medical intervention.

Santha, Sreevidya; Dwivedi, Chandradhar

2015-06-01

Effective management of tumorigenesis requires development of better anticancer agents with greater efficacy and fewer side-effects. Natural products are important sources for the development of chemotherapeutic agents and almost 60% of anticancer drugs are of natural origin. α-Santlol, a sesquiterpene isolated from Sandalwood, is known for a variety of therapeutic properties including anti-inflammatory, anti-oxidant, anti-viral and anti-bacterial activities. Cell line and animal studies reported chemopreventive effects of sandalwood oil and α-santalol without causing toxic side-effects. Our laboratory identified its anticancer effects in chemically-induced skin carcinogenesis in CD-1 and SENCAR mice, ultraviolet-B-induced skin carcinogenesis in SKH-1 mice and in vitro models of melanoma, non-melanoma, breast and prostate cancer. Its ability to induce cell-cycle arrest and apoptosis in cancer cells is its most reported anticancer mechanism of action. The present review discusses studies that support the anticancer effect and the mode of action of sandalwood oil and α-santalol in carcinogenesis.

2015-01-01

Electroconvulsive therapy (ECT) is an effective biological treatment option for severely depressed elderly patients; however, it can cause cognitive side effects, including anterograde and retrograde amnesia. Elderly patients with "cognitive impairment no dementia" (CIND) are reported as being more vulnerable to the cognitive side effects of ECT compared with patients with "no cognitive impairment" (NCI). The few studies that have reached this conclusion can be criticized for using insensitive outcome measures. The present study investigated cognitive side effects using standard neuropsychological tests before and after twice-weekly ECT. Patients were assessed at baseline (T1) and within one week after a course of ECT (consisting of a mean of 10 treatments) (T2), and were followed up for three months after T2 (T3). The sample included 54 patients with NCI (n = 36) or CIND (n = 18). For a control group, we recruited 17 healthy elderly persons. Tests of anterograde memory, information-processing speed, executive function, and retrograde memory were administered. We computed reliable change indices using simple regression methods. Short-term side effects were detected at T2 in a large minority of patients, with no significant differences between NCI and CIND patients. Considerable improvement in global cognitive function from T1 to T3 was observed in 44% of the CIND patients. At the group level, information-processing speed improved significantly in CIND vs. NCI patients. CIND patients were not more vulnerable to amnesia than were NCI patients. Long-term cognitive side effects of ECT were not detected.

2014-01-01

Background. Infantile hemangiomas (IHs) are the most common benign tumours of infancy. Propranolol has recently been reported to be a highly effective treatment for IHs. This study aimed to evaluate the efficacy and side effects of propranolol for treatment of complicated cases of IHs. Patients and Methods. This prospective clinical study included 30 children with huge or complicated IHs; their ages ranged from 2 months to 1 year. They were treated by oral propranolol. Treatment outcomes were clinically evaluated. Results. Superficial cutaneous hemangiomas began to respond to propranolol therapy within one to two weeks after the onset of treatment. The mean treatment period that was needed for the occurrence of complete resolution was 9.4 months. Treatment with propranolol was well tolerated and had few side effects. No rebound growth of the tumors was noted when propranolol dosing stopped except in one case. Conclusion. Propranolol is a promising treatment for IHs without obvious side effects. However, further studies with longer follow-up periods are needed. PMID:24899888

Airway compromise secondary to vagus nerve stimulator: case report and implications for otolaryngologists.

PubMed

Bhatt, Y M; Hans, P S; Belloso, A

2010-05-01

Vagus nerve stimulators are devices used in the management of patients with drug-refractory epilepsy unsuitable for resective or disconnective surgery. Implanted usually by neurosurgeons, these devices are infrequently encountered by otolaryngologists. Despite significant anti-seizure efficacy, side effects related to laryngopharyngeal stimulation are not uncommon. A 28-year-old man with a history of effective vagus nerve stimulator use presented with a cluster of seizures and respiratory distress associated with intermittent stridor. The duration of stridor corresponded to the period of vagus nerve stimulation. Endoscopy revealed forced adduction of the left vocal fold against a medialised right vocal fold. The device was switched off and the stridor immediately resolved. Airway compromise is an under-recognised side effect of vagus nerve stimulation. We describe the first known case of stridor and contralateral vocal fold palsy in a vagus nerve stimulator user. We highlight the need for better understanding amongst otolaryngologists of the laryngopharyngeal side effects of this technology.

Structure–Function Studies of Hydrophobic Residues That Clamp a Basic Glutamate Side Chain during Catalysis by Triosephosphate Isomerase

PubMed Central

2016-01-01

Kinetic parameters are reported for the reactions of whole substrates (kcat/Km, M–1 s–1) (R)-glyceraldehyde 3-phosphate (GAP) and dihydroxyacetone phosphate (DHAP) and for the substrate pieces [(kcat/Km)E·HPi/Kd, M–2 s–1] glycolaldehyde (GA) and phosphite dianion (HPi) catalyzed by the I172A/L232A mutant of triosephosphate isomerase from Trypanosoma brucei brucei (TbbTIM). A comparison with the corresponding parameters for wild-type, I172A, and L232A TbbTIM-catalyzed reactions shows that the effect of I172A and L232A mutations on ΔG⧧ for the wild-type TbbTIM-catalyzed reactions of the substrate pieces is nearly the same as the effect of the same mutations on TbbTIM previously mutated at the second side chain. This provides strong evidence that mutation of the first hydrophobic side chain does not affect the functioning of the second side chain in catalysis of the reactions of the substrate pieces. By contrast, the effects of I172A and L232A mutations on ΔG⧧ for wild-type TbbTIM-catalyzed reactions of the whole substrate are different from the effect of the same mutations on TbbTIM previously mutated at the second side chain. This is due to the change in the rate-determining step that determines the barrier to the isomerization reaction. X-ray crystal structures are reported for I172A, L232A, and I172A/L232A TIMs and for the complexes of these mutants to the intermediate analogue phosphoglycolate (PGA). The structures of the PGA complexes with wild-type and mutant enzymes are nearly superimposable, except that the space opened by replacement of the hydrophobic side chain is occupied by a water molecule that lies ∼3.5 Å from the basic side chain of Glu167. The new water at I172A mutant TbbTIM provides a simple rationalization for the increase in the activation barrier ΔG⧧ observed for mutant enzyme-catalyzed reactions of the whole substrate and substrate pieces. By contrast, the new water at the L232A mutant does not predict the decrease in ΔG⧧ observed for the mutant enzyme-catalyzed reactions of the substrate piece GA. PMID:27149328

Airway hemangiomas can be difficult to manage and cause anxiety in both the parents and the treating physician. Propranolol, a nonselective beta-blocker, has recently been used for treating proliferating infantile hemangiomas. We report successful management of a proliferating, large, mixed infantile hemangioma with subglottic extension in an Indian infant using oral propranolol in a dose of 2mg/kg/day without any side effects. Induction of early involution and freedom from the side effects of steroid therapy seem encouraging for using propranolol as a first line treatment modality in the management of troublesome hemangiomas. © 2013 The International Society of Dermatology.

A jaundiced bodybuilder Cholestatic hepatitis as side effect of injectable anabolic-androgenic steroids.

The use of anabolic steroids is prevalent in recreational athletes. This case report describes a young amateur bodybuilder who was referred to our outpatient clinic with jaundice and loss of appetite due to cholestatic hepatitis. Additional tests including a liver biopsy made it likely that the hepatitis was caused by the injectable anabolic steroid trenbolone enanthate. Cholestatic hepatitis may not be limited to the use of oral anabolic-androgenic steroids, as is widely assumed. Therefore, and because of other side effects, the recreational use of all forms of anabolic steroids should be discouraged.

The primary tumor location has a prognostic impact in metastatic colorectal cancer (mCRC). We report the results from retrospective analyses assessing the effect of tumor location on prognosis and efficacy of second- and later-line panitumumab treatment in patients with RAS wild-type (WT) mCRC and on prognosis in all lines of treatment in patients with RAS mutant (MT) mCRC. RAS WT data (n = 483) from 2 randomized phase III panitumumab trials (ClinicalTrials.gov identifiers, NCT00339183 and NCT00113763) were analyzed for treatment outcomes stratified by tumor location. The second analysis assessed the effect of tumor location in RAS MT patients (n = 1205) from 4 panitumumab studies (ClinicalTrials.gov identifiers, NCT00364013, NCT00819780, NCT00339183, and NCT00113763). Primary tumors located in the cecum to transverse colon were coded as right-sided; those located from the splenic flexure to the rectum were coded as left-sided. Of all patients, the tumor location was ascertained for 83% to 88%; 71% to 77% of patients had left-sided tumors. RAS WT patients with right-sided tumors did worse for all efficacy parameters compared with those with left-sided tumors. The patients with left-sided tumors had better outcomes with panitumumab than with the comparator treatment. Because of the low patient numbers, no conclusions could be drawn for right-sided mCRC. The prognostic effect of tumor location on survival was unclear for RAS MT patients. These retrospective analyses have confirmed that RAS WT right-sided mCRC is associated with a poor prognosis, regardless of the treatment. RAS WT patients with left-sided tumors benefitted from the addition of panitumumab in second or later treatment lines. Further research is warranted to determine the optimum management of right-sided mCRC and RAS MT tumors. Copyright © 2018 Elsevier Inc. All rights reserved.

Background: Clozapine is a second-generation antipsychotic drug used in treatment-resistant schizophrenia. Fever induced by clozapine is a rather frequent side-effect which usually occurs in the first 4 weeks of treatment. Despite its effectiveness, there are potentially life-threatening adverse effects, such as cardiotoxicity. Case Report: We present the case of a 31- year-old caucasian male with refractory schizophrenia who developed benign fever, increase of C-reactive protein and high troponin levels, without presenting any other signs to myocarditis, on the 13th day under clozapine treatment, which declined progressively upon discontinuation of the drug. Discussion: This case hints at the presence of initially subclinical cardiotoxicity as an underlying factor in patients developing fever. Conclusion: Taking advantage of more sensitive methods for measuring troponin, clinicians would be promptly aware of this possible side-effect. This would allow for significant reduction of the risk of cardiac dysfunction, further attained by carefully monitoring the patient. PMID:28064233

Cannabidiol (CBD), one of the major products of the marijuana plant, is devoid of marijuana's typical psychological effects. In contrast, potential antipsychotic efficacy has been suggested based on preclinical and clinical data (Zuardi et al., 2002). In this report, we further investigated the efficacy and safety of CBD monotherapy in three patients with treatment-resistant schizophrenia (TRS). This was an in-patient study. All patients were given placebo for the initial 5 days, and from the 6th to 35th day (inclusive) they received CBD (initial oral dose of 40 mg reaching 1280 mg/day). On the 36th day, CBD treatment was discontinued and replaced by placebo for 5 days, which was subsequently switched to olanzapine for over 15 days. Efficacy, tolerability and side effects were assessed. One patient showed mild improvement, but two patients didn't show any improvement during CBD monotherapy. All patients tolerated CBD very well and no side effects were reported. These preliminary data suggest that CBD monotherapy may not be effective for TRS.

Background Sensory neuropathy (paresthesias), tinnitus, hearing impairment, and Raynaud phenomena are side effects of cisplatin-based chemotherapy used to treat testicular cancer patients. We assessed the long-term occurrence of these side effects among testicular cancer survivors according to the treatment they received. Methods A total of 1814 men who were treated for unilateral testicular cancer in Norway during 1980–1994 were invited to participate in a national multicenter follow-up survey conducted during 1998–2002. The men were allocated to six groups according to the treatment they had received. Self-reported symptoms were assessed by a mailed questionnaire that included the Scale for Chemotherapy-Induced Neurotoxicity. A total of 1409 participants who responded to the questionnaire and/or underwent audiometry were assessable in this study. Respondents to the questionnaire (n = 1402) scored the relevant symptoms according to how troubled they were by each (not at all, a little, quite a bit, or very much). Hearing impairment was objectively assessed by audiometry at 4000 Hz in 755 men (seven of whom did not respond to the questionnaire). Group comparisons of symptom assessments were performed with χ2 or Kruskal–Wallis tests. Associations between relevant factors and self-reported symptoms or hearing impairment measured by audiometry were assessed using proportional odds ordinal logistic regression models and linear regression models, respectively. All statistical tests were two-sided. Results The median follow-up for the 1409 assessable men was 10.7 years (range = 4–21 years). All chemotherapy groups had statistically significantly higher odds for increasing severity of all assessed symptoms and inferior audiometric results compared with men who did not receive chemotherapy. Among chemotherapy-treated men, 39% (95% confidence interval [CI] = 35% to 43%) reported Raynaud-like phenomena (defined as white or cold hands or fingers [or feet or toes] on cold exposure), 29% (95% CI = 25% to 33%) reported paresthesias in the hands or feet, 21% (95% CI = 18% to 25%) reported hearing impairment, and 22% (95% CI = 19% to 26%) reported tinnitus as major symptoms troubling them quite a bit or very much. Hearing impairment (odds ratio [OR] = 5.3, 95% CI = 3.0 to 9.2) and tinnitus (OR = 7.1, 95% CI = 4.1 to 12.4) were particularly common in the dose-intensive chemotherapy group compared with the no chemotherapy group. Men who were treated with radiotherapy had higher odds of self-reported paresthesias in feet compared with those not treated with radiotherapy (OR = 1.5, 95% CI = 1.01 to 2.1, P = .04). Conclusion Long-term survivors of testicular cancer who were treated with cisplatin-based chemotherapy were more often troubled by dose-dependent neurological side effects and Raynaud-like phenomena compared with those who were not treated with chemotherapy.

No blank slates: Pre-existing schemas about pharmaceuticals predict memory for side effects.

PubMed

Heller, Monika K; Chapman, Sarah C E; Horne, Rob

2017-04-01

Attribution of symptoms as medication side effects is informed by pre-existing beliefs about medicines and perceptions of personal sensitivity to their effects (pharmaceutical schemas). We tested whether (1) pharmaceutical schemas were associated with memory (recall/recognition) for side effect information (2) memory explained the attribution of a common unrelated symptom as a side effect. In this analogue study participants saw the patient leaflet of a fictitious asthma drug listing eight side effects. We measured recall and recognition memory for side effects and used a vignette to test whether participants attributed an unlisted common symptom (headache) as a side effect. Participants who perceived pharmaceuticals as more harmful in general recalled fewer side effects correctly (r Correct Recall  = -.273), were less able to differentiate between listed and unlisted side effects (r Recognition Sensitivity  = -.256) and were more likely to attribute the unlisted headache symptom as a side effect (r side effect attribution  = .381, ps < .01). The effect of harm beliefs on side effect attribution was partially mediated by correct recall of side effects. Pharmaceutical schemas are associated with memory for side effect information. Memory may explain part of the association between pharmaceutical schemas and the attribution of unrelated symptoms as side effects.

Interactions between antiepileptic drugs and hormones.

Svalheim, Sigrid; Sveberg, Line; Mochol, Monika; Taubøll, Erik

2015-05-01

Antiepileptic drugs (AEDs) are known to have endocrine side effects in both men and women. These can affect fertility, sexuality, thyroid function, and bone health, all functions of major importance for well-being and quality of life. The liver enzyme inducing antiepileptic drugs (EIAEDs), like phenobarbital, phenytoin, and carbamazepine, and also valproate (VPA), a non-EIAED, are most likely to cause such side effects. AED treatment can alter the levels of different sex hormones. EIAEDs increase sex hormone binding globulin (SHBG) concentrations in both men and women. Over time, this elevation can lead to lower levels of bioactive testosterone and estradiol, which may cause menstrual disturbances, sexual problems, and eventually reduced fertility. VPA can cause weight gain in both men and women. In women, VPA can also lead to androgenization with increased serum testosterone concentrations, menstrual disturbances, and polycystic ovaries. Lamotrigine has not been shown to result in endocrine side effects. The newer AEDs have not yet been thoroughly studied, but case reports indicate that some of these drugs could also be suspected to cause such effects if endocrine changes commence after treatment initiation. It is important to be aware of possible endocrine side effects of AEDs as they can have a major impact on quality of life, and are, at least partly, reversible after AED discontinuation.

To identify the medications used by patients with dysphonia, describe the voice symptoms reported on initial speech-language pathology (SLP) examination, evaluate the possible direct and indirect effects of medications on voice production, and determine the association between direct and indirect adverse voice effects and self-reported voice symptoms, hydration and smoking habits, comorbidities, vocal assessment, and type and degree of dysphonia. This is a retrospective cross-sectional study. Fifty-five patients were evaluated and the vocal signs and symptoms indicated in the Dysphonia Risk Protocol were considered, as well as data on hydration, smoking and medication use. We analyzed the associations between type of side effect and self-reported vocal signs/symptoms, hydration, smoking, comorbidities, type of dysphonia, and auditory-perceptual and acoustic parameters. Sixty percent were women, the mean age was 51.8 years, 29 symptoms were reported on the screening, and 73 active ingredients were identified with 8.2% directly and 91.8% indirectly affecting vocal function. There were associations between the use of drugs with direct adverse voice effects, self-reported symptoms, general degree of vocal deviation, and pitch deviation. The symptoms of dry throat and shortness of breath were associated with the direct vocal side effect of the medicine, as well as the general degree of vocal deviation and the greater pitch deviation. Shortness of breath when speaking was also associated with the greatest degree of vocal deviation. Copyright © 2017 The Voice Foundation. Published by Elsevier Inc. All rights reserved.

Modulation of p-Cyanophenylalanine Fluorescence by Amino Acid Side-chains and Rational Design of Fluorescence Probes of α-Helix Formation

p-Cyanophenylalanine is an extremely useful fluorescence probe of protein structure which can be recombinantly and chemically incorporated into proteins. The probe has been used to study protein folding, protein-membrane interactions, protein-peptide interactions and amyloid formation, however the factors that control its fluorescence are not fully understood. Hydrogen bonding to the cyano group is known to play a major role in modulating the fluorescence quantum yield, but the role of potential side-chain quenchers has not yet been elucidated. A systematic study on the effects of different side-chains on p-cyanophenylalanine fluorescence is reported. Tyr is found to have the largest effect followed by deprotonated His, Met, Cys, protonated His, Asn, Arg, and protonated Lys. Deprotonated amino groups are much more effective fluorescence quenchers than protonated amino groups. Free neutral imidazole and hydroxide ion are also effective quenchers of p-cyanophenylalanine fluorescence with Stern-Volmer constants of 39.8 M−1 and 22.1 M−1, respectively. The quenching of p-cyanophenylalanine fluorescence by specific side-chains is exploited to develop specific, high sensitivity, fluorescence probes of helix formation. The approach is demonstrated with Ala based peptides that contain a p-cyanophenylalanine-His or a p-cyanophenylalanine-Tyr pair located at positions i and i+4. The p-cyanophenylalanine-His pair is most useful when the His side-chain is deprotonated and is, thus, complimentary to Trp-His pair which is most sensitive when the His side-chain is protonated.

[Intoxication by powdered seeds of horse chestnut (Aesculus hippocastanum) used nasally as snuff - a case report].

PubMed

Zając, Maciej; Wiśniewski, Marek; Sein Anand, Jacek

2014-01-01

There are only few reports in the medical literature about side effects and toxicity of horse chestnut (Aesculus hippocastanum). We report a 15-year-old woman who was admitted to the hospital because of symptoms including: vomiting, dyspnea, burning in the nose and throat, and syncope, after intranasal snuff of powdered horse chestnut seeds. Laboratory tests showed no abnormalities. After 2 days of hospitalization the female was discharged home with subjective and objective improvement. Preparation and use of snuff is related to the tradition of the kashubian region. The powder formed from horse chestnuts, which is white in color, effects after about 5-10 minutes, and causes severe irritation of the nasal mucous membranes, which results in sneezing. Responsible for side effects is mainly aescin. The most frequently observed aescin intoxication symptoms were gastrointestinal irritation and allergic reactions. Intoxication by powdered seeds of horse chestnut used nasally as snuff may lead, as it was in our case, to sudden and self-limiting clinical symptoms. Supportive therapy and a short hospital observation seems to be sufficient in such cases.

Difference in dummy responses in matched side impact tests of vehicles with and without side airbags.

Insurance Institute for Highway Safety (IIHS) high-hooded side impacts were analyzed for matched vehicle tests with and without side airbags. The comparison provides a measure of the effectiveness of side airbags in reducing biomechanical responses for near-side occupants struck by trucks, SUVs, and vans at 50 km/h. The IIHS moving deformable barrier (MDB) uses a high-hooded barrier face. It weighs 1,500 kg and impacts the driver side perpendicular to the vehicle at 50 km/h. SID IIs dummies are placed in the driver and left second-row seats. They represent fifth percentile female occupants. IIHS tests were reviewed for matches with one test with a side airbag and another without it in 2003-2007 model year (MY) vehicles. Four side airbag systems were evaluated: (1) curtain and torso side airbags, (2) head and torso side airbag, (3) curtain side airbag, and (4) torso side airbag. There were 24 matched IIHS vehicle tests: 13 with and without a curtain and torso side airbags, 4 with and without a head and torso side airbag, 5 with and without a side curtain airbag, and 2 with and without a torso airbag. The head, chest, and pelvis responses were compared for each match and the average difference was determined across all matches for a type of side airbag. The average reduction in head injury criterion (HIC) was 68 ± 16% (P < .001) with curtain and torso side airbags compared to the HIC without side airbags. The average HIC was 296 with curtain and torso side airbags and 1,199 without them. The viscous response (VC) was reduced 54 ± 19% (P < .005) with curtain and torso side airbags. The combined acetabulum and ilium force (7 ± 15%) and pelvic acceleration (-2 ± 17%) were essentially similar in the matched tests. The head and torso side airbag reduced HIC by 42 ± 30% (P < .1) and VC by 32 ± 26% compared to vehicles without a side airbag. The average HIC was 397 with the side head and torso airbag compared to 729 without it. The curtain airbag and torso airbag only showed lower head responses but essentially no difference in the chest and pelvis responses. The curtain and torso side airbags effectively reduced biomechanical responses for the head and chest in 50 km/h side impacts with a high-hooded deformable barrier. The reductions in the IIHS tests are directionally the same as estimated fatality reductions in field crashes reported by NHTSA for side airbags.

C-peptide inhibitors of Ebola virus glycoprotein-mediated cell entry: effects of conjugation to cholesterol and side chain-side chain crosslinking.

We previously described potent inhibition of Ebola virus entry by a 'C-peptide' based on the GP2 C-heptad repeat region (CHR) targeted to endosomes ('Tat-Ebo'). Here, we report the synthesis and evaluation of C-peptides conjugated to cholesterol, and Tat-Ebo analogs containing covalent side chain-side chain crosslinks to promote α-helical conformation. We found that the cholesterol-conjugated C-peptides were potent inhibitors of Ebola virus glycoprotein (GP)-mediated cell entry (~10(3)-fold reduction in infection at 40 μM). However, this mechanism of inhibition is somewhat non-specific because the cholesterol-conjugated peptides also inhibited cell entry mediated by vesicular stomatitis virus glycoprotein G. One side chain-side chain crosslinked peptide had moderately higher activity than the parent compound Tat-Ebo. Circular dichroism revealed that the cholesterol-conjugated peptides unexpectedly formed a strong α-helical conformation that was independent of concentration. Side chain-side chain crosslinking enhanced α-helical stability of the Tat-Ebo variants, but only at neutral pH. These result provide insight into mechanisms of C-peptide inhibiton of Ebola virus GP-mediated cell entry. Copyright © 2013 Elsevier Ltd. All rights reserved.

To examine whether somatoform symptoms, specifically symptoms of conversion, somatization, and hypochondriasis, are associated with side-effect reporting and treatment nonadherence in depressed family medicine outpatients, and to measure whether symptoms improve with pharmacotherapy. Inception cohort study with 14-week follow-up. Inner-city family medicine residency clinic. Thirty-nine consecutive adults with major depressive disorder were asked to participate, and 30 consented. Antidepressants for 14 weeks. The Personality Assessment Inventory (PAI) was administered before treatment. The PAI is a self-reported inventory compatible with the Diagnostic and Statistical Manual of Mental Disorders, Fourth Edition, designed to measure a broad range of personality characteristics. After 14 weeks, the side-effect incidence and treatment nonadherence rates were determined, and 12 patients were readministered the PAI. Depressed family medicine patients demonstrated trends toward elevated Somatic Complaints scale and conversion subscale scores and a lower Suicidal Ideation scale score relative to those of a standardized depressed psychiatric patient profile. Conversion and hypochondriacal symptoms were associated with side-effect reporting and treatment nonadherence. Somatization and hypochondriacal symptoms improved clinically and statistically during treatment for depression. Somatoform distress is a complex, common, and understudied phenomenon in primary care that can adversely affect the treatment of depression. Somatoform symptoms of conversion and hypochondriasis, but not somatization, were found to be risk factors for treatment nonadherence. Somatization and hypochondriacal symptoms may represent personality states that improve with pharmacotherapy, and conversion symptoms may be a personality trait resistant to medical treatment for depression.

The common cold is one of the most common illnesses in humans and constitutes an economic burden both in terms of productivity and expenditure for treatment. There is no proven cure for the common cold and symptomatic relief is the mainstay of treatment. The use of intranasal ipratropium bromide (IB) has been addressed in several studies and might prove an effective treatment for the common cold. To determine the effect of IB versus placebo or no treatment on severity of rhinorrhoea and nasal congestion in children and adults with the common cold. Subjective overall improvement was another primary outcome and side effects were reported as a secondary outcome. We searched the Cochrane Central Register of Controlled Trials (CENTRAL 2011, Issue 1) which contains the Acute Respiratory Infections Group's Specialised Register, MEDLINE (1950 to January week 4, 2011), MEDLINE in-process and other non-indexed citations (February 2011), EMBASE (1974 to February 2011), AMED (1985 to February 2011), Biosis (1974 to February 2011) and LILACS (1985 to February 2011). Randomised controlled trials (RCTs) comparing IB to placebo or no treatment in children and adults with the common cold. Two review authors independently extracted data and assessed trial quality. We used a standardised form to extract relevant data and we contacted trial authors for additional information. Seven trials with a total of 2144 participants were included. Four studies (1959 participants) addressed subjective change in severity of rhinorrhoea. All studies were consistent in reporting statistically significant changes in favour of IB. Nasal congestion was reported in four studies and was found to have no significant change between the two groups. Two studies found a positive response in the IB group for the global assessment of overall improvement. Side effects were more frequent in the IB group, odds ratio (OR) 2.09 (95% confidence interval (CI) 1.40 to 3.11). Commonly encountered side effects included nasal dryness, blood tinged mucus and epistaxis. For people with the common cold, the existing evidence, which has some limitations, suggests that IB is likely to be effective in ameliorating rhinorrhoea. IB had no effect on nasal congestion and its use was associated with more side effects compared to placebo or no treatment although these appeared to be well-tolerated and self-limiting. There is a need for larger, high-quality trials to determine the effectiveness of IB in relieving common cold symptoms.

Infantile hemangioma: treatment with short course systemic corticosteroid therapy as an alternative for propranolol.

Infantile hemangiomas (IHs) are increasingly being treated with propranolol or other beta-blockers, but before this therapeutic option was available, oral glucocorticosteroids (GCSs) were the criterion standard treatment and are still the alternative modality in problematic cases. Nevertheless, there is no standard treatment protocol for the dose and duration of GCSs. Long-term treatment with GCSs is associated with unwanted side effects such as growth suppression, behavioral changes, and reflux. Twenty-one children with troublesome IHs were treated according to an algorithm with 3 mg/kg/day of oral prednisolone divided three times per day with varying duration and number of GCS courses. Two blinded investigators independently interpreted therapy results using the Hemangioma Activity Score (HAS). Side effects were determined according to reports in patient charts and parental questionnaires. The median duration of a short course of GCSs was 2 weeks (range 1-6 weeks). The number of courses was 2 (range 1-5). The median cumulative dose was 91 mg/kg. Growth stabilized in all patients, with a good response (>50% reduction in HAS) in 62% and a favorable response (30-50% reduction is HAS) in 23%. Twelve of the 21 children (57%) had minor side effects. Persistent side effects did not occur. Intermittent short course, systemic, high-dose GCS therapy is an effective and safe treatment modality for IH, with a substantially lower cumulative dose of GCSs compared to prolonged therapy and no major side effects. This treatment is an alternative in cases in which propranolol fails or is contraindicated. © 2012 Wiley Periodicals, Inc.

Efficacy and tolerability of oral lacosamide as adjunctive therapy in pediatric patients with pharmacoresistant focal epilepsy.

The results of adjunctive lacosamide treatment in 18 pediatric patients with pharmacoresistant focal epilepsy are reported. All had severe forms of focal epilepsy with or without secondary generalization and were concurrently receiving one to three other antiepileptic drugs. Lacosamide was administered orally, and final dose, after slow titration, ranged between 1.7 and 10 mg/kg. Mean treatment duration was 8 months (range=3 weeks-17 months). Treatment efficacy was assessed at two time points with a 1-year interval. The reported greater than 50% reduction in seizure frequency was 36% in the initial short-term and 20% in the following long-term assessment. Side effects, mostly somnolence and irritability, were reported by 39% of patients in both evaluations. Our data suggest that lacosamide treatment in pediatric patients is safe at doses up to 10 mg/kg/day without any major side effects, but studies in larger series are needed to validate and extend these findings.

To determine in detail the complications associated with the use of mandibular repositioning splints (MRS) to treat sleep-related breathing disorders. This prospective cross-sectional cohort study audits the management with mandibular repositioning splints of 121 patients suffering from sleep-related breathing disorders. Investigation of patients' and sleeping partners' perspectives on treatment was undertaken with the use of a questionnaire based study. Sixty-eight per cent of respondents reported that they were compliant with treatment; various side effects were reported of which excess salivation was the most common. Investigation of sleeping partners' perspectives revealed that 70% felt that their partners' snoring was improved and 47% felt that their partner's breathing pauses during sleep were reduced. Sixty-four per cent of the sleeping partners also reported that their own sleep pattern had improved since their partner's treatment. Mandibular repositioning splints used in the manner described by this paper are demonstrated to have a good compliance rate, provide successful treatment and exhibit only minor, reversible side effects.

Evidence-based recommendations are available for the management of androgen deprivation therapy (ADT)-induced side effects; however, there are no data on the implementation of the recommendations into daily practice patterns. To compare practice patterns in the management of ADT-induced side effects with evidence-based strategies. A European Web-based survey was conducted from January 16, 2015, to June 24, 2015. The 25-item questionnaire was designed with the aid of expert opinion and covered general respondent information, ADT preference per disease stage, patient communication on ADT-induced side effects, and strategies to mitigate side effects. All questions referred to patients with long-term ADT use. Reported practice patterns were compared with available evidence-based strategies. Following data collection, descriptive statistics were used for analysis. Frequency distributions were compiled and compared using a generalised chi-square test. In total, 489 eligible respondents completed the survey. Luteinising hormone-releasing hormone-agonist with or without an antiandrogen was the preferred method of ADT in different settings. Patients were well informed about loss of libido (90%), hot flushes (85%), fatigue (67%), and osteoporosis (63%). An osteoporotic and metabolic risk assessment prior to commencing ADT was done by one-quarter of physicians. The majority (85%) took preventive measures and applied at least one evidence-based strategy. Exercise was recommended by three-quarters of physicians who advocate its positive effects; however, only 25% of physicians had access to exercise programmes. Although the minimum sample size was set at 400 participants, the current survey remains susceptible to volunteer and nonresponder bias. Patients were well informed about several ADT-induced complications but uncommonly underwent an osteoporotic and metabolic risk assessment. Nevertheless, physicians partially provided evidence-based strategies for the management of the complications. Physicians often advised exercise to reduce ADT-induced side effects, but programmes were not widely available. Implementation of evidence-based strategies for androgen deprivation therapy-induced side effects in real-life practice patterns should be improved. Copyright © 2016 European Association of Urology.

Promethazine and its use as a treatment for space motion sickness

NASA Technical Reports Server (NTRS)

Bagian, James P.; Beck, Bradley G.

1993-01-01

Until Mar. 1989, no effective treatment--either prophylactic or symptomatic--for space motion sickness (SMS) had been discovered. Since Mar. 1989, intramuscular (IM) promethazine (PMZ) has been used in the treatment of SMS with extremely favorably results reported by the crew. A retrospective study was undertaken to quantify the efficacy of IM PMZ since its institution and the incidence of its major anticipated side-effect drowsiness and sedation. The results from a standardized crew medical debriefing conducted immediately after landing and follow-up interviews with the crews were used in establishing the efficacy and incidence of side effects from treatment. Only crews from the first 44 Shuttle flights on their first mission were considered. For a total of 132 crewmembers, 96 exhibited symptoms of SMS; and, of these, 20 were treated with IM PMZ. Ninety percent of those receiving IM PMZ 25-50mg received nearly immediate (less than 2 hours) relief of symptoms and 75 percent required no further treatment through the first 2 days of spaceflight. Those not receiving this treatment did not have any near-term resolution of their symptoms, and 50 percent were still ill through the second day of flight. This represents a significant difference at the p = 0.46 level. In stark contrast to the 60 percent to 73 percent incidence of sedation or drowsiness reported in individuals treated with PMZ in terrestrial environment at the doses used here, less than 5 percent reported these symptoms during spaceflight. IM PMZ is an effective therapy for SMS and is associated with minimal incidence of sedation or drowsiness. This combination of efficacy that is absent of significant side effects represents a substantial improvement in the operational situation of crewmembers afflicted with SMS. Studies to understand the mechanisms underlying these observations will be undertaken in the future.

Steroid therapy for persistent or recurrent nummular adenoviral keratoconjunctivitis (AK) has little benefit because of the frequent recurrences, and mostly "offers" only serious steroid side effects. Since January 1995, we have treated different patients with nummuli after AK with topical Ciclosporin A (CSA) in an attempt to achieve at least the same symptomatic effect as with steroids, however, without side effects. Here, we report about our experiences in a very severe case with longterm treatment. The patient was sent to our clinic 4 months after AK with confluent nummuli and Descemet folds, more severe in the right than in the left eye. Best corrected visual acuity was 0.05 in the right and 0.5 in the left eye. Topical CSA 2% 4 times daily was first administered only in the right eye. When after 6 weeks a reduction of nummuli was noted in the right eye, the left eye, which had not improved, was started on the same regime. Therapy was tapered and finally stopped after 12 months in the right and 10 months in the left eye, when only minor changes were left in the corneae. A prompt recurrence of nummuli in both eyes within 4 weeks forced us to resume CSA therapy. At present, both corneae are clear with full vision, and this result is stable with 1 drop of CSA daily. No side effects of CSA therapy have been noted. The disappearance of nummuli with topical CSA and even more the reappearance of nummuli after cessation of CSA therapy show that topical CSA is about as effective as topical steroids in the symptomatic treatment of non-scarred nummuli after KE without the serious steroid side effects. Topical CSA treatment of nummuli after KE is, therefore, a very recommendable alternative for the potentially dangerous steroid therapy. Generally valid data on risk of recurrences, dosage and general effectiveness could only be learned from prospective studies with large numbers of AK patients, which, however, are not available outside epidemics.

Botulinum toxin serotype A injections used in treating dynamic wrinkles is one of the least invasive cosmetic procedures. High patient satisfaction and low onset of always moderate side effects contribute to the growing popularity of botulinum toxin injections in cosmetic treatment over the past few years. Years of experience and use, in therapeutics [1,2] and esthetics (20 years) have proven the efficacy and the safety of this wrinkle treatment. Today, no severe or long-term side effects have been reported in esthetics. This article discusses only the most frequent locoregional effects. They are rare, moderate, transitory, and totally reversible. Properly informing and selecting patients will contribute to successfully preventing and managing these effects.

Infrared coagulation: a new treatment for hemorrhoids

Many methods, which have effectively reduced the number of patients requiring hospital admission, have been described for the outpatient treatment of hemorrhoids. However, complications have been reported, and the methods are often associated with unpleasant side effects. In 1977 Neiger et al. described a new method that used infrared coagulation, which produced minimal side effects. The authors have conducted a prospective, randomized trial to evaluate infrared coagulation compared with more traditional methods of treatment. The authors' results show that it may be more effective than injection sclerotherapy in treating non-prolapsing hemorrhoids and that it compares favorably with rubber band ligationmore » in most prolapsing hemorrhoids. No complications occurred, and significantly fewer patients experienced pain after infrared coagulation (P . less than 0.001).« less

Respiratory dyskinesia is an under-recognized side effect of neuroleptic administration. There are only few studies that have addressed the prevalence of respiratory dyskinesia in patients with tardive dyskinesia. Our case report highlights the need to regularly examine patients on antipsychotics for any evidence of dyskinetic movements including respiratory musculature. Since RD is underrecognized and misdiagnosed, early detection can improve long term prognosis as treatment options are few and usually of only limited effect. A 62-year-old Asian male, retired civil engineer, had more than 20 years history of depressive illness, developed antidepressant induced hypomania, and was given risperidone upto 1 mg per day. He developed extrapyrmidal side effects as tremors, rigidity and later dyskinetic movements of lips with shortness of breathing, dyspnoea, grunting or gasping. He was referred to the pulmonologist who got the neccessary medical work up done, which was normal. A diagnosis of respiratory dyskinesia was made. Respiratory dyskinesia is an under-recognised and distressing condition that clinicians need to be aware of when treating patients with anti-psychotic medications. And also there is a need to regularly examine patients on antipsychotics for any evidence of dyskinetic movements including respiratory musculature for early diagnosis and better outcome. This case report also is worth reading for professionals of other specialties also because of the presentation of this patient, it can be easily misdiagnosed and result in poor outcome.

OBJECTIVES: The objective of this study was to evaluate the safety and efficacy of polyethylene glycol-electrolyte solution vs polyethylene glycol-3350 for the treatment of fecal impaction in pediatric patients. METHODS: A retrospective, observational, institutional review board–approved study was conducted over a 1-year time period. Patients were included in the study if they were admitted to the hospital with a diagnosis of fecal impaction or constipation and were treated with either polyethylene glycol-electrolyte solution (PEG-ES) or polyethylene glycol-3350 (PEG-3350). Patients were excluded if they were discharged prior to resolution of treatment and/or did not receive PEG-ES or PEG-3350. RESULTS: Fifty-one patients (ranging in age from 1 month to 15 years) were evaluated: 23 patients received PEG-ES and 28 patients received PEG-3350. Sex, race, age, and weight were not statistically different between the 2 groups. Resolution of fecal impaction was not significantly different between PEG-ES vs PEG-3350 (87% and 86%, respectively; p = 0.87). There was only 1 reported side effect with PEG-3350, vs 11 reported side effects with PEG-ES (p < 0.01). CONCLUSIONS: Theses results suggest that PEG-3350 is as effective as PEG-ES for the treatment of fecal impaction in pediatric patients and is associated with fewer side effects. PMID:26170773

Experiences With a Self-Reported Mobile Phone-Based System Among Patients With Colorectal Cancer: A Qualitative Study

PubMed Central

2016-01-01

Background In cancer care, mobile phone-based systems are becoming more widely used in the assessment, monitoring, and management of side effects. Objective To explore the experiences of patients with colorectal cancer on using a mobile phone-based system for reporting neurotoxic side effects. Methods Eleven patients were interviewed (ages 44-68 years). A semistructured interview guide was used to perform telephone interviews. The interviews were transcribed verbatim and analyzed with qualitative content analysis. Results The patients' experiences of using a mobile phone-based system were identified and constructed as: “being involved,” “pacing oneself,” and “managing the questions.” “Being involved” refers to their individual feelings. Patients were participating in their own care by being observant of the side effects they were experiencing. They were aware that the answers they gave were monitored in real time and taken into account by health care professionals when planning further treatment. “Pacing oneself” describes how the patients can have an impact on the time and place they choose to answer the questions. Answering the questionnaire was easy, and despite the substantial number of questions, it was quickly completed. “Managing the questions” pointed out that the patients needed to be observant because of the construction of the questions. They could not routinely answer all the questions. Patients understood that side effects can vary during the cycles of treatment and need to be assessed repeatedly during treatment. Conclusions This mobile phone-based system reinforced the patients’ feeling of involvement in their own care. The patients were comfortable with the technology and appreciated that the system was not time consuming. PMID:27282257

Risk factors for non-adherence to antidepressant treatment in patients with mood disorders.

Adherence to antidepressant therapy by patients with depressive disorders is essential not only to achieve a positive patient outcome but also to prevent a relapse. The aim of this study was to identify potential modelling factors influencing adherence to antidepressant treatment by patients with mood disorders in the community mental health care setting A total of 160 consecutive psychiatric outpatients attending two Community Mental Health Centres on Tenerife Island between September 2011 and May 2012 were asked to participate in the study; of these, 145 accepted. The Morisky self-report scale was used to assess adherence. The potential predictors examined included socio-demographic, clinical and therapeutic variables. The Clinical Global Impression-Severity and -Improvement scales and the Beck Depression Inventory were used for clinical assessment. Drug treatment side-effects were assessed using the "Self-report Antidepressant Side-Effect Checklist." All participants were also asked to complete the "Drug Attitude Inventory" (DAI), "Beliefs about Medicine Questionnaire" (BMQ), and "Leeds Attitude towards concordance Scale". Discriminant analyses were performed to predict non-adherence. There was no clear correlation between adherence and the socio-demographic variables examined, but adherence was related to a positive attitude of the patients towards his/her treatment (DAI) and low scores in the BMQ-Harm and -Concern subscales. Non-adherence was also related to an increasing severity of depression and to the presence and severity of side-effects. Among our study cohort, the profiles of adherent patients to antidepressant treatment were more closely associated with each patient's attitudes and beliefs than to objective socio-demographic variables. The severity of depression played a relevant role in adherence, but whether this role is direct or an interaction with several concurrent factors is not yet clear. Side-effects were also closely related to adherence, as conditioned by frequent polypharmacy.

Use of side-chain for rational design of n-type diketopyrrolopyrrole-based conjugated polymers: what did we find out?

The primary role of substituted side chains in organic semiconductors is to increase their solubility in common organic solvents. In the recent past, many literature reports have suggested that the side chains play a critical role in molecular packing and strongly impact the charge transport properties of conjugated polymers. In this work, we have investigated the influence of side-chains on the charge transport behavior of a novel class of diketopyrrolopyrrole (DPP) based alternating copolymers. To investigate the role of side-chains, we prepared four diketopyrrolopyrrole-diketopyrrolopyrrole (DPP-DPP) conjugated polymers with varied side-chains and carried out a systematic study of thin film microstructure and charge transport properties in polymer thin-film transistors (PTFTs). Combining results obtained from grazing incidence X-ray diffraction (GIXD) and charge transport properties in PTFTs, we conclude side-chains have a strong influence on molecular packing, thin film microstructure, and the charge carrier mobility of DPP-DPP copolymers. However, the influence of side-chains on optical properties was moderate. The preferential "edge-on" packing and dominant n-channel behavior with exceptionally high field-effect electron mobility values of >1 cm(2) V(-1) s(-1) were observed by incorporating hydrophilic (triethylene glycol) and hydrophobic side-chains of alternate DPP units. In contrast, moderate electron and hole mobilities were observed by incorporation of branched hydrophobic side-chains. This work clearly demonstrates that the subtle balance between hydrophobicity and hydrophilicity induced by side-chains is a powerful strategy to alter the molecular packing and improve the ambipolar charge transport properties in DPP-DPP based conjugated polymers. Theoretical analysis supports the conclusion that the side-chains influence polymer properties through morphology changes, as there is no effect on the electronic properties in the gas phase. The exceptional electron mobility is at least partially a result of the strong intramolecular conjugation of the donor and acceptor as evidenced by the unusually wide conduction band of the polymer.

Monopolar radiofrequency facial tightening: a retrospective analysis of efficacy and safety in over 600 treatments.

Monopolar radiofrequency skin heating coupled with cryogen cooling of facial skin for skin tightening has been utilized on over 10,000 patients since 2002. In order to establish the actual rate and degree of side effects in our clinical experience, a retrospective chart review was performed. Charts and clinical images of over 600 consecutive patient treatments between May 2002 and June 2006 using a monopolar radiofrequency device (Thermacool, Thermage, Haywood, CA) for skin tightening at the Maryland Laser, Skin and Vein Institute were retrospectively reviewed. The primary presentation for treatment was skin laxity of the lower face. Treatment was delivered with a 1-cm2 standard tip at fluences of 81 to 124 J/cm2 (level of 12.5 to 15), a 1-cm2 "fast" tip at fluences of 62 to 109 J/cm2 (level of 72.0 to 76.0), a 1.5-cm2 "big fast" tip at fluences of 75 to 130 J/cm2 (level of 61.5 to 65), and a 3-cm2 "bigger" tip at equivalent fluences as each became available. As treatment algorithms evolved over 4 years, the algorithm of multiple passes at lower fluence associated with better clinical outcomes and greater patient acceptance has been adopted. The most common immediate and expected clinical effects were erythema and edema lasting less than 24 hours, although 6 patients reported edema lasting for up to 1 week. There were no permanent side effects. In total, 2.7% of treatments resulted in temporary side effects, the most significant of which was a slight depression on the cheek (n = 1), which completely resolved within 3.5 months. Other side effects included localized areas of acneiform subcutaneous erythematous papules (n = 4) and a linear superficial crust (n = 1) with the original tip, all of which resolved within 1 week. One patient reported small erythematous subcutaneous nodules resolving in 17 days. Tenderness of the neck lasting from 2 weeks (n = 2) to 3 weeks (n = 1) was also reported. Our data, obtained in an office setting without injectable anesthetic or i.v. sedation, indicate that monopolar RF for skin tightening is a very safe procedure. The treatment algorithm and tips have evolved over several years leading to increased safety and efficacy. Side effects are infrequent, self-limited, and minor, comparing favorably to other nonablative devices utilized for facial rejuvenation.

Chronic prostatitis/chronic pelvic pain syndrome (CP/CPPS) is a chronic pelvic pain condition largely refractory to treatment. Cannabis (marijuana) use has been reported for a wide variety of chronic pain conditions, but no study has examined prevalence of cannabis use, symptom benefit or side effects, or frequency in CP/CPPS. Participants were recruited from an outpatient CP/CPPS urology clinic (n = 98) and online through the Prostatitis Foundation website (n = 244). Participants completed questionnaires (demographics, CP/CPPS, depression, cannabis). The clinic sample included Canadian patients and the online sample included primarily American patients. Due to differences, groups were examined separately. Almost 50% of respondents reported using cannabis (clinic n = 49; online n = 89). Of the cannabis users, 36.8% of clinic and 75% of online respondents reported that it improved their symptoms. Most of the respondents (from the clinic and online groups) reported that cannabis improved their mood, pain, muscle spasms, and sleep. However, they did not note any improvements for weakness, fatigue, numbness, ambulation, and urination. Overall, the effectiveness of cannabis for CP/CPPS was "somewhat/very effective" (57% clinic; 63% online). There were no differences between side effects or choice of consumption and most reported using cannabis rarely. These are the first estimates in men suffering from CP/CPPS and suggest that while cannabis use is prevalent, its medical use and benefit are unknown. This is an understudied area and the benefit or hazard for cannabis use awaits further study.

Drug side effects are one of main concerns in the drug discovery, which gains wide attentions. Investigating drug side effects is of great importance, and the computational prediction can help to guide wet experiments. As far as we known, a great number of computational methods have been proposed for the side effect predictions. The assumption that similar drugs may induce same side effects is usually employed for modeling, and how to calculate the drug-drug similarity is critical in the side effect predictions. In this paper, we present a novel measure of drug-drug similarity named "linear neighborhood similarity", which is calculated in a drug feature space by exploring linear neighborhood relationship. Then, we transfer the similarity from the feature space into the side effect space, and predict drug side effects by propagating known side effect information through a similarity-based graph. Under a unified frame based on the linear neighborhood similarity, we propose method "LNSM" and its extension "LNSM-SMI" to predict side effects of new drugs, and propose the method "LNSM-MSE" to predict unobserved side effect of approved drugs. We evaluate the performances of LNSM and LNSM-SMI in predicting side effects of new drugs, and evaluate the performances of LNSM-MSE in predicting missing side effects of approved drugs. The results demonstrate that the linear neighborhood similarity can improve the performances of side effect prediction, and the linear neighborhood similarity-based methods can outperform existing side effect prediction methods. More importantly, the proposed methods can predict side effects of new drugs as well as unobserved side effects of approved drugs under a unified frame.

Objective To extract physician-asserted drug side effects from electronic medical record clinical narratives. Materials and methods Pattern matching rules were manually developed through examining keywords and expression patterns of side effects to discover an individual side effect and causative drug relationship. A combination of machine learning (C4.5) using side effect keyword features and pattern matching rules was used to extract sentences that contain side effect and causative drug pairs, enabling the system to discover most side effect occurrences. Our system was implemented as a module within the clinical Text Analysis and Knowledge Extraction System. Results The system was tested in the domain of psychiatry and psychology. The rule-based system extracting side effects and causative drugs produced an F score of 0.80 (0.55 excluding allergy section). The hybrid system identifying side effect sentences had an F score of 0.75 (0.56 excluding allergy section) but covered more side effect and causative drug pairs than individual side effect extraction. Discussion The rule-based system was able to identify most side effects expressed by clear indication words. More sophisticated semantic processing is required to handle complex side effect descriptions in the narrative. We demonstrated that our system can be trained to identify sentences with complex side effect descriptions that can be submitted to a human expert for further abstraction. Conclusion Our system was able to extract most physician-asserted drug side effects. It can be used in either an automated mode for side effect extraction or semi-automated mode to identify side effect sentences that can significantly simplify abstraction by a human expert.

What matters when judging intentionality-moral content or normative status? Testing the rational scientist model of the side-effect.

PubMed

Papadopoulos, C; Hayes, B K

2018-06-01

Previous work has demonstrated a "side-effect effect," such that intentionality is more likely to be attributed to agents who bring about negatively valenced as opposed to positively valenced side effects. The rational-scientist model explains this by suggesting that norm-violating side effects are more informative for inferring intentionality than norm-conforming side effects. In the present study we reexamined this account, addressing limitations of previous empirical tests (e.g., Uttich & Lombrozo, Cognition 116: 87-100, 2010). Side-effect valence and norm status were manipulated factorially, enabling an examination of the impact of norm status on intentionality judgments in both positively and negatively valenced side effects. Additionally, the impact of side-effect norm status on the perceived valences of side effects and agents was examined. Effects of norm status were found for both positive and negative side effects. Violation of an ostensibly neutral norm led to negative perceptions of the side effect. However, a norm status effect on intentionality judgments persisted when these effects were controlled. These results support the view that the side-effect effect is the result of the rational use of social-cognitive evidence.

Frontal Plane Knee Moments in Golf: Effect of Target Side Foot Position at Address

PubMed Central

Lynn, Scott K.; Noffal, Guillermo J.

2010-01-01

Golf has the potential to keep people active well into their later years. Injuries to the target side knee have been reported in golfers, yet no mechanisms for these injuries have been proposed. The loads on the knee during the golf swing may be insufficient to cause acute injury, yet they may be a factor in the progression of overuse/degenerative conditions; therefore, research developing swing modifications that may alter loading of the knee is warranted. It has been suggested that the proper golf set-up position has the target-side foot externally rotated but no reasoning for this modification has been provided. Frontal plane knee moments have been implicated in many knee pathologies. Therefore, this study used a 3-dimensional link segment model to quantify the frontal plane knee moments during the golf swing in a straight (STR) and externally rotated (EXT) target-side foot position. Subjects were 7 collegiate golfers and knee moments were compared between conditions using repeated measures T-tests. The golf swing knee moment magnitudes were also descriptively compared to those reported for two athletic maneuvers (drop jump landing, side-step cutting) and activities of daily living (gait, stair ascent). The EXT condition decreased the peak knee adduction moment as compared to the STR condition; however, foot position had no effect on the peak knee abduction moment. Also, the magnitude of the knee adduction moments during the two activities of daily living were 9-33% smaller than those experienced during the two different golfing conditions. The drop jump landing and golf swing knee moments were of similar magnitude (STR= - 5%, EXT= + 8%); however, the moments associated with side- step cutting were 50-71% larger than those on the target side knee during the golf swing. The loading of the target side knee during the golf swing may be a factor in the development and progression of knee pathologies and further research should examine ways of attenuating these loads through exercise and swing modifications. Key points An externally rotated front foot position at address would be recommended for those with medial knee pathology in the target side limb. There is a large valgus moment on the target side knee during the golf swing that is not decreased with external rotation of the foot at address. The potential of the knee moments on the target side limb to lead to knee pathologies in golfers needs to be further investigated. PMID:24149696

LSD Flashbacks - The Appearance of New Visual Imagery Not Experienced During Initial Intoxication: Two Case Reports.

G Lerner, Arturo; Goodman, Craig; Rudinski, Dmitri; Lev-Ran, Shaul

2014-01-01

A side effect associated with the use of synthetic hallucinogens such as lysergic acid diethylamide-(LSD) is the partial or total recurrence of perceptual disturbances which previously appeared during intoxication, despite absence of recent use. These are commonly referred to as "flashbacks" or Hallucinogen Persisting Perception Disorder (HPPD). Here we present two cases of patients with a prior history of LSD use who turned to psychiatric consultation following brief episodes of HPPD. Surprisingly, in both cases new visual imagery appeared during episodes of flashbacks which was not experienced during primary LSD use. Both subjects reported the ability to discern between LSD-associated visual disturbances and new visual imagery. This phenomenon did not cause functional impairment and in both cases caused gradual concern due to its persistence. Both patients refused medical treatment and continued psychiatric follow-up. At one year follow-up both patients reported almost complete spontaneous remission. To the best of our knowledge these are the first reported cases of LSD-related benign flashbacks in which new imagery is experienced. Reasons for this reversible and apparently harmless side effect are proposed. Conclusions from case reports should be taken with caution.

This study aimed to use the Patient Reported Information Multidimensional Exploration (PRIME) framework, a novel ensemble of machine-learning and deep-learning algorithms, to extract, analyze, and correlate self-reported information from Online Cancer Support Groups (OCSG) by patients (and partners of patients) with low intermediate-risk prostate cancer (PCa) undergoing radical prostatectomy (RP), external beam radiotherapy (EBRT), and active surveillance (AS), and to investigate its efficacy in quality-of-life (QoL) and emotion measures. From patient-reported information on 10 OCSG, the PRIME framework automatically filtered and extracted conversations on low intermediate-risk PCa with active user participation. Side effects as well as emotional and QoL outcomes for 6084 patients were analyzed. Side-effect profiles differed between the methods analyzed, with men after RP having more urinary and sexual side effects and men after EBRT having more bowel symptoms. Key findings from the analysis of emotional expressions showed that PCa patients younger than 40 years expressed significantly high positive and negative emotions compared with other age groups, that partners of patients expressed more negative emotions than the patients, and that selected cohorts (< 40 years, > 70 years, partners of patients) have frequently used the same terms to express their emotions, which is indicative of QoL issues specific to those cohorts. Despite recent advances in patient-centerd care, patient emotions are largely overlooked, especially in younger men with a diagnosis of PCa and their partners. The authors present a novel approach, the PRIME framework, to extract, analyze, and correlate key patient factors. This framework improves understanding of QoL and identifies low intermediate-risk PCa patients who require additional support.

Objective: The objective of this study was to assess the acceptability, content validity and usability of the My Medicines and Me (M3Q) self-report side effect questionnaire. Methods: Eight focus groups consisting of mental health patients, carers, general practitioners, psychiatrists, mental health nurses and pharmacists were conducted, involving 78 participants. Two researchers independently examined the transcriptions and analysed the data thematically using an inductive method. Results: The findings supported changes to the formatting, length and phrasing of questions in the original version of the questionnaire. Although the groups provided differing views on the usability of the M3Q in clinical practice, the patient and carer groups were unconditionally in favour of such a tool to be used systematically to describe patients’ subjective experiences with side effects. Conclusion: The differing contribution made by all groups involved in the administration and completion of the M3Q assisted with content validity of the questionnaire. The acceptability and usability of this novel side effect questionnaire was also explored, with many participants agreeing it was a necessary tool for a patient centred approach to treatment. Following implementation of the changes to the current format of the questionnaire, investigation into the uptake and use in clinical practice should be carried out. PMID:26557985

Oral contraceptive pills (OCs) are a commonly prescribed method of birth control for sexually experienced adolescents. The purpose of the current study was to describe anticipated parental involvement and adolescent compliance with pill taking, and to describe experiences with a 20-mcg OC regarding satisfaction and side effects after six cycles. Anticipated parental involvement and anticipated compliance, and experiences with an OC, were assessed at baseline, and after the first and sixth cycles during a clinical trial of oral contraceptives, which required parental consent. Three adolescent medicine clinics in New York, NY; Cincinnati, OH; and San Juan, Puerto Rico. The sample consisted of 43 female adolescents with a mean age of 17 years. The majority of adolescents living with a parent anticipated parental involvement, and few adolescents anticipated difficulties with consistent pill taking. For two side effects (weight and mood changes), more than 30% of the adolescents anticipated the occurrence or worsening of side effects. However, few adolescents actually experienced increases in any of the nine side effects assessed. Ninety-seven percent of adolescents in this trial reported being satisfied with a 20-mcg OC. Health care providers can assess adolescents' anticipated difficulties with compliance with daily pill taking, and desire for help from their parents. This information can be incorporated into counseling to promote consistent and correct use.

The Risks and Benefits of Cannabis in the Dermatology Clinic.

PubMed

Dhadwal, Gurbir; Kirchhof, Mark G

Cannabis ( Cannabis sativa/indica), also known as marijuana, has been used for medicinal and recreational purposes for millennia. There has been a recent trend to legalize the use of cannabis, as illustrated by the recent legalization votes in numerous states in the United States and legislation in Canada to allow recreational cannabis use. With this increasing consumption of cannabis, dermatologists will see increased pressure to prescribe cannabis and will see the side effects of cannabis use with greater frequency. There are several approved medical indications for cannabis use, including psoriasis, lupus, nail-patella syndrome, and severe pain. In addition, very preliminary studies have suggested cannabis and its derivatives might have use in acne, dermatitis, pruritus, wound healing, and skin cancer. Further well-controlled studies are required to explore these potential uses. Conversely, the side effects of cannabis use are relatively well documented, and dermatologists should be aware of these presentations. Side effects of cannabis use include cannabis allergy manifesting as urticaria and pruritus, cannabis arteritis presenting with necrosis and ulcers, and oral cancers from cannabis smoke. In this review, we summarize some of the studies and reports regarding the medicinal uses of cannabis in the dermatology clinic and some of the side effects that might present more often to dermatologists as the use of cannabis increases.

The east side of the Uncompahgre River Basin has been a known contributor of dissolved selenium to recipient streams. Discharge of groundwater containing dissolved selenium contributes to surface-water selenium concentrations and loads; however, the groundwater system on the east side of the Uncompahgre River Basin is not well characterized. The U.S. Geological Survey, in cooperation with the Colorado Water Conservation Board and the Bureau of Reclamation, has established a groundwater-monitoring network on the east side of the Uncompahgre River Basin. Ten monitoring wells were installed during October and November 2012. This report presents location data, lithologic logs, well-construction diagrams, and well-development information. Understanding the groundwater system will provide managers with an additional metric for evaluating the effectiveness of salinity and selenium control projects.

Is side-viewing endoscope assisted balloon dilatation better for corrosive gastric outlet obstruction?

Endoscopic balloon dilatation (EBD) is an effective therapy for caustic-induced gastric outlet obstruction (GOO). Gaining access to the stricture site is the most important step. It is sometimes difficult to negotiate a balloon through the stricture with a front-viewing endoscope due to deformed anatomy of stomach. To overcome this technical difficulty, a side-viewing endoscope can be used. There is limited data regarding the use of side-viewing endoscopes in EBD. We here report on the short-term efficacy and safety of EBD in caustic-induced GOO. In technically difficult cases, a side-viewing endoscope was used for EBD and its efficacy and safety were assessed. The study included 25 patients with caustic-induced GOO. Patients underwent EBD using a through-the-scope balloon. Initial balloon dilatation was performed with a front-viewing endoscope. A side-viewing endoscope was used where negotiation across the stricture failed with a front-viewing endoscope. Dilatation was started at 8 mm diameter and was performed at 1-week intervals. The end point of dilatation was 15 mm diameter. In 18 patients successful balloon dilatation was possible with a front-viewing endoscope. A side-viewing endoscope was used in six patients as negotiation across the stricture was not possible with a front-viewing endoscope. In all six patients negotiation across the stricture followed by successful dilatation was successful with a side-viewing endoscope. Of the 25 patients included in this study, 24 (96%) achieved procedural success (18 with a front-viewing endoscope and 6 with a side-viewing endoscope) in 3-9 sessions. Our results show that EBD is a safe and effective option for caustic-induced GOO and in difficult cases a side-viewing endoscope can be used to achieve technical success.

We report and demonstrate an optical refractometer based on a compact fiber Michelson interferometer. The Michelson interferometer is composed of an asymmetrical twin-core fiber containing a central core and a side core. By chemically etching a segment of the twin-core fiber until the side core is exposed, the effective index of the side core in the etched region is sensitive to the environmental refractive index, which leads to a shift of the transmission spectrum of the Michelson interferometer. The experimental results show that such a device has a refractive index resolution of more than 800 nm/refractive index unit in the range of 1.34-1.37. © 2011 Optical Society of America

While the literature on prostate cancer health-related quality of life has grown extensively, little is known about symptom management strategies used by men to manage treatment-related side effects and the effectiveness of those strategies. We collected 628 symptom management reports from 98 men treated for localized prostate cancer. Participants were recruited from email lists and a prostate cancer clinic in Northern California. Data were collected using the Critical Incident Technique. Symptom management reports were assigned to categories of urinary, sexual, bowel, mental health, systemic, or "other." We calculated descriptive statistics by symptom type and management strategy effectiveness. The most common symptoms were urinary (26 %) and sexual (23 %). Participants' symptom management strategies varied widely, from medical and surgical interventions (20 %) to behavioral strategies (11 %) to diet and lifestyle interventions (12 %). The effectiveness of symptom management strategies varied, with sexual symptoms being managed effectively only 47 % of the time to mental health symptom management strategies considered effective 89 % of the time. Doing nothing was a commonly reported (15 %) response to symptoms and was effective only 14 % of the time. Men report the least effectiveness in symptom management for sexual dysfunction after prostate cancer treatment. Including men's experience with managing treatment side effects may be an important way to improve survivorship programs and make them more acceptable to men. More work is needed to find out why men frequently do nothing in response to symptoms when effective solutions exist and how providers can successfully engage such men.

Side effects associated with anti-HIV drugs.

Highleyman, L

1998-04-01

Many side effects are associated with the use of anti-HIV drugs, impacting the development of drug resistance and the quality of life for HIV-patients. Concern about side effects is a primary factor in deterring people from beginning HIV therapy. Frequency and severity of side effects vary greatly, but they are frequently more common and severe in people who are taking a new drug or who have advanced HIV disease. Information on side effects comes largely from clinical trials; however, many side effects are not discovered until the drug has been approved and used by larger numbers of people. Side effects vary from serious toxicities that require stopping treatment to uncomfortable or annoying side effects that interfere with daily life. A table categorizes the four major side effects (nausea, fever, skin rash, and fatigue) and divides them into grades that describe their intensity. A chart lists the side effects associated with specific anti-HIV drugs. Suggestions for managing side effects are included.

Drug delivery systems (DDSs) with biocompatibility and precise drug delivery are eagerly needed to overcome the paradox in chemotherapy that high drug doses are required to compensate for the poor biodistribution of drugs with frequent dose-related side effects. In this work, we reported a metal-organic framework (MOF) based tumor targeting DDS developed by a one-pot, and organic solvent-free ``green'' post-synthetic surface modification procedure, starting from the nanoscale MOF MIL-101. Owing to the multifunctional surface coating, premature drug release from this DDS was prevented. Due to the pH responsive benzoic imine bond and the redox responsive disulfide bond at the modified surface, this DDS exhibited tumor acid environment enhanced cellular uptake and intracellular reducing environment triggered drug release. In vitro and in vivo results showed that DOX loaded into this DDS exhibited effective cancer cell inhibition with much reduced side effects.Drug delivery systems (DDSs) with biocompatibility and precise drug delivery are eagerly needed to overcome the paradox in chemotherapy that high drug doses are required to compensate for the poor biodistribution of drugs with frequent dose-related side effects.

The present study aims to assess the influence of ultra-low doses of opioid antagonists on the analgesic properties of opioids and their side effects. In the present randomized, double-blind controlled trial, the influence of the combination of ultra-low-dose naltrexone and morphine on the total opioid requirement and the frequency of the subsequent side effects was compared with that of morphine alone (added with placebo) in patients with trauma in the upper or lower extremities. Although the morphine and naltrexone group required 0.04 mg more opioids during the study period, there was no significant difference between the opioid requirements of the 2 groups. Nausea was less frequently reported in patients receiving morphine and naltrexone. The combination of ultra-low-dose naltrexone and morphine in extremity trauma does not affect the opioid requirements; it, however, lowers the risk of nausea. Copyright © 2012 Elsevier Inc.

1988-01-01

Clenbuterol is a betamimetic agent with a marked effect on the adrenergic beta-2-receptors relevant for tocolysis. The influence on beta-1-receptors of the heart, resulting in cardiovascular side effects is far less. The substance is resorbed almost completely enterally and has a half-life of 34 hours. Consequently, ingestion intervals of 12 hours are possible, resulting in a good acceptance of the tocolytic, therapy and a noticeable improvement of the patients compliance. Clenbuterol was applied in 37 cases in the course of a clinical test. Initially, the dose was 0.04 mg b.i.d., after 24 hours 0.02 mg b.i.d. In cases of cervix-effective, premature labor, an objectively measureable tocolytic effect was achieved. Subjectively reported side effects, i.e. palpation, tachycardia and tremor, were noticeably weaker than under fenoterol therapy. There was no indication of clenbuterol-related cardiotoxicity regarding continuous measurement of heart-specific enzymes, i.e. CK-MB and serum myoglobin. No pathologic alterations were found in the EKGs. Therefore, regarding indications and contraindications for beta-adrenergic agents, clenbuterol appears to have good tocolytic properties, with the advantages of less cardiac side effects, better compliance and a better dose-effect-ratio compared with the common oral tocolysis with fenoterol.

There are currently no head-to-head comparisons of sialagogues for Primary Sjögren's syndrome (pSS). We compared the tolerability and side effect profile of pilocarpine and cevimeline in patients with pSS and determined clinical, laboratory and pathological variables associated with therapeutic failure. We retrospectively reviewed the use of pilocarpine and cevimeline in 118 patients with pSS who fulfilled the 2002 American European Consensus Group criteria in a University-based setting. Clinical, laboratory and pathological baseline variables were collected. Failure of therapy was defined as the clinician or patient's decision to stop treatment either due to lack of efficacy or side effects. Cevimeline was associated with lower failure rates compared to pilocarpine among first-time users: 27% vs. 47% (p=0.02), and all users: 32% vs. 61% (p<0.001). Severe sweating was the most frequent side effect leading to cessation of therapy and occurred more frequently in pilocarpine (25%) than cevimeline (11%) users (p=0.02). Patients who previously failed one secretagogue were less likely to discontinue treatment with the other agent, 52% of first-time users vs. 27% of second-time users (p=0.004). Only ANA positivity was associated with failure: [59% vs. 38%] (p=0.03). pSS patients were more likely to continue cevimeline than pilocarpine long-term due to fewer reported side effects with cevimeline. Therapeutic failure of one secretagogue did not predict similar results with the other since second time users were more likely to continue long-term treatment.

BACKGROUND Hyperlipidemia is one of the important diseases in pregnancy that causes fetal abnormalities during pregnancy and after the birth. Unfortunately, the usual anti-fat drugs are associated with high morbidity in fetus and due to people's inclination towards taking herbs, it is required to identify side effects of medicinal herbs in pregnancy. The aim of this study was to present hypolipidemic herbs that would not any complications for mother and fetus. METHODS In this review article, the major electronic databases such as EBSCO, Central Register of Controlled Trials (CENTRAL), China Network Knowledge Infrastructure (CNKI), Cochrane, Google scholar, MEDLINE, SciVerse, Scopus, and Web of Science were searched using the key words “herbal” and “hyperlipidemia”, “herbal” and “pregnancy” matched by MeSH from their respective inceptions till September, 2016. Total of 1723 publications (145 review articles, 855 original research articles, and 723 abstracts) about the effect of herbals on hyperlipidemia and 682 publications (200 abstracts, 423 original research articles, and 59 review articles) about the effect of herbals in pregnancy were retrieved. At the end, a list of medicinal plants effective on hyperlipidemia alongside their effects on pregnancy was developed. Finally, the plants effective on hyperlipidemia and safe during pregnancy were determined and their dosage, complications, mechanism of action, and side effects were reported. RESULTS A total of 110 effective herbs on hyperlipidemia were identified and complications of 95 plants in pregnancy were studied. At last, among the 55 selected plants effective on hyperlipidemia and examined for pregnancy, we reported 12 herbs with their dosage and special considerations that can be used to treat hyperlipidemia during pregnancy. CONCLUSION Some medicinal plants can be used to treat hyperlipidemia during pregnancy without any significant side effects both on mother or fetus. PMID:29147122

Side effects prompt some patients to forego otherwise-beneficial therapies. This study explored which characteristics make side effects particularly aversive. We used a psychometric approach, originating from research on risk perception, to identify the factors (or components) underlying side effect perceptions. Women ( N = 149) aged 40 to 74 years were recruited from a patient registry to complete an online experiment. Participants were presented with hypothetical scenarios in which an effective and necessary medication conferred a small risk of a single side effect (e.g., nausea, dizziness). They rated a broad range of side effects on several characteristics (e.g., embarrassing, treatable). In addition, we collected 4 measures of aversiveness for each side effect: choosing to take the medication, willingness to pay to avoid the side effect (WTP), negative affective attitude associated with the side effect, and how each side effect ranks among others in terms of undesirability. A principal components analysis (PCA) was used to identify the components underlying side effect perceptions. Then, for each aversiveness measure separately, regression analyses were used to determine which components predicted differences in aversiveness among the side effects. The PCA revealed 4 components underlying side effect perceptions: affective challenge (e.g., frightening), social challenge (e.g., disfiguring), physical challenge (e.g., painful), and familiarity (e.g., common). Side effects perceived as affectively and physically challenging elicited the highest levels of aversiveness across all 4 measures. Understanding what side effect characteristics are most aversive may inform interventions to improve medical decisions and facilitate the translation of novel biomedical therapies into clinical practice.

[Vedolizumab (Entyvio®) for the treatment of inflammatory bowel diseases].

PubMed

Van Kemseke, C; Louis, E; Reenaers, C

2015-11-01

Anti-TNF agents are highly effective in treating inflammatory bowel diseases, but loss of response and side-effects leading to drug interruption are often reported. New molecules are needed to treat these patients. Vedolizumab is a fully humanized anti-body inhibiting the migration of circulating lymphocytes to the gut by binding the integrin α4β7. In ulcerative colitis, clinical response, remission and mucosal healing were observed at 6 weeks in 47%, 17% and 40% of the patients, respectively. The maintenance study demonstrated 42% and 52% of clinical remission and response at week 52. In Crohn's disease, clinical response and remission were respectively observed in 15% and 31% of the patients at 6 weeks. Clinical remission at week 52 was 39%. The time to clinical response was longer in patients who had failed anti-TNF. The safety profile is excellent with the same proportion of side-effects in the placebo and in the treated groups. The most frequently reported adverse events were pharyngitis and headaches.

The Auckland Stillbirth study demonstrated a two-fold increased risk of late stillbirth for women who did not go to sleep on their left side. Two further studies have confirmed an increased risk of late stillbirth with supine sleep position. As sleep position is modifiable, we surveyed self-reported late pregnancy sleep position, knowledge about sleep position, and views about changing going-to-sleep position. Participants in this 2014 survey were pregnant women (n = 377) in their third trimester from South Auckland, New Zealand, a multi-ethnic and predominantly low socio-economic population. An ethnically-representative sample was obtained using random sampling. Multivariable logistic regression was performed to identify factors independently associated with non-left sided going-to-sleep position in late pregnancy. Respondents were 28 to 42 weeks' gestation. Reported going-to-sleep position in the last week was left side (30%), right side (22%), supine (3%), either side (39%) and other (6%). Two thirds (68%) reported they had received advice about sleep position. Non-left sleepers were asked if they would be able to change to their left side if it was better for their baby; 87% reported they would have little or no difficulty changing. Women who reported a non-left going-to-sleep position were more likely to be of Maori (aOR 2.64 95% CI 1.23-5.66) or Pacific (aOR 2.91 95% CI 1.46-5.78) ethnicity; had a lower body mass index (BMI) (aOR 0.93 95% CI 0.89-0.96); and were less likely to sleep on the left-hand side of the bed (aOR 3.29 95% CI 2.03-5.32). Maternal going-to-sleep position in the last week was side-lying in 91% of participants. The majority had received advice to sleep on their side or avoid supine sleep position. Sleeping on the left-hand side of the bed was associated with going-to-sleep on the left side. Most non-left sleepers reported their sleeping position could be modified to the left side suggesting a public health intervention about sleep position is likely to be feasible in other multi-ethnic communities.

Case report: polyuria related to dexmedetomidine.

PubMed

Pratt, Alexandra; Aboudara, Matthew; Lung, Linn

2013-07-01

Dexmedetomidine has become a popular sedative in the intensive care unit for patients undergoing mechanical ventilation because of its highly selective α-2 agonism, which exerts a combination of anesthetic, analgesic, and anxiolytic effects. Bradycardia and hypotension have been reported as the most common side effects of its use in large studies. Dexmedetomidine has been reported to induce polyuria by suppressing vasopressin secretion and increasing permeability of the collecting ducts in a dose-dependent fashion. We report a case of dexmedetomidine-related polyuria that occurred with a high-dose continuous infusion and subsequently resolved with discontinuation of the drug. (Anesth Analg 2013;117:150-2).

Differential Patient-Caregiver Opinions of Treatment and Care For Advanced Lung Cancer Patients

PubMed Central

Zyzanski, Stephen J; Siminoff, Laura A

2010-01-01

This study examined the differences of opinion between cancer patients and caregivers with regard to treatment and care decisions. 184 advanced lung cancer patients and 171 primary caregivers were recruited as a convenience sample from clinics in Cleveland, Ohio. A telephone interview was conducted to collect data using a semi-structured questionnaire. Nonparametric tests and regression analysis were performed. The findings showed that patients and caregivers reported significant disagreement on three main issues: trade-off between treatment side effects and benefits; reporting treatment side effects to physicians, and hospice care. Caregivers were more concerned about patient’s quality of life and more willing to discuss hospice issues than were patients. Perceived family disagreement is associated with depression in both patients and caregivers. The study provided empirical evidence for patient-caregiver disagreement about treatment and care decisions and its significant adverse impact on both patients and caregivers. PMID:20137849

Nivolumab is a fully human IgG4 monoclonal antibody directed against programmed cell death protein 1 (PD-1). PD-1 inhibition allows T-cell activation and recruitment to destroy cancer cells. Checkpoint inhibitors have shown significant survival advantage and relatively low side-effects in comparison with conventional chemotherapy in several types of advanced cancer. Granulomatous cutaneous reactions have been reported showing sarcoidal and panniculitic morphology. Here we present a case of drug-induced lichenoid and granulomatous dermatitis after checkpoint inhibitor therapy observed in a 63-year-old male treated with nivolumab for advanced glioblastoma. This morphology has not been previously reported. We documented a high number of CD8+ T-cells within the lesions. Additionally, we review the side-effects observed with the use of checkpoint inhibitors, with special focus on cutaneous manifestations. © 2018 John Wiley & Sons A/S.

Docetaxel is an antimicrotubules cytotoxic agent prescribed widely by medical oncologists in multiple tumor types (breast, lung, prostate, stomach, head, and neck). However, the side effects of docetaxel are numerous (cytopenia, peripheral edema, myalgia, arthralgia, alopecia, and sensitive neuropathy) and recent concerns have been raised about neutropenic enterocolitis in France. Here, we report the case of a 57-year-old patient with metastatic prostatic cancer, who developed a severe myositis and fasciitis grade IV 1 week after his second docetaxel infusion. We reviewed the five cases of docetaxel-related myositis described in the literature, and found that most of them occurred in patients with diabetes (n=5/5) or hypertension (n=4/5). A vascular toxicity may explain this severe complication, and patients with diabetes or hypertension should be monitored closely in the context of a docetaxel chemotherapy.

Objective. To assess the effect of communication style, and frequency and severity of medication side-effects, on pharmacy students' perception of risk of experiencing side effects. Methods. One hundred responses from pharmacy students were obtained using an online survey. Participants were presented with a drug information box containing drug name, drug usage, and one side-effect associated with the drug. Information on side-effect for each drug was presented in one of eight experimental conditions, in a 2 (side-effect frequency: low, high), X2 (side-effect severity: mild, severe) X2 (communication style: verbal, verbal + natural frequency) factorial design. Risk perception of experiencing side effects was measured. Results. Communication style was found to have a significant impact on risk perception depending on the context of frequency and severity associated with the side effect. Conclusion. Communication style plays a significant role in formulating risk perceptions of medication side effects. Training in pharmaceutical counseling should include special emphasis on effective language use.

2015-11-01

Interpretation of epidemiological studies on health effects from mobile phone use is hindered by uncertainties in the exposure assessment. We used a newly developed smartphone application (app) to validate self-reported mobile phone use and behaviour among adults. 107 participants (mean age 41.4 years) in the Netherlands either downloaded the software app on their smartphone or were provided with a study smartphone for 4 weeks. The app recorded the number and duration of calls, text messages, data transfer, laterality and hands-free use. Self-reported mobile phone use was collected before using the app and after 6 months through an interviewer-administered questionnaire. The geometric mean ratios (GMR, 95% CI) and Spearman correlations (r) of self-reported (after 6 months) versus recorded number and duration of calls were: GMR=0.65 (0.53 to 0.80), r=0.53; and GMR=1.11 (0.86 to 1.42), r=0.57 respectively. Participants held the phone on average for 86% of the total call time near the head. Self-reported right side users held the phone for 70.7% of the total call time on the right side of the head, and left side users for 66.2% on the left side of the head. The percentage of total call time that the use of hands-free devices (headset, speaker mode, Bluetooth) was recorded increased with increasing frequency of reported hands-free device usage. The observed recall errors and precision of reported laterality and hands-free use can be used to quantify and improve radiofrequency exposure models based on self-reported mobile phone use.

Epidural analgesia side effects, co-interventions, and care of women during childbirth: a systematic review.

PubMed

Mayberry, Linda J; Clemmens, Donna; De, Anindya

2002-05-01

The purpose of this article is to profile research findings targeting the intrapartum care implications of the most common side effects and co-interventions that go along with the use of epidural analgesia during labor. Randomized, controlled trials published in English from 1990 to 2000 that addressed each of the targeted side effects and 3 specified co-interventions were evaluated for inclusion in this report. Side effects such as pruritus, nausea, and hypotension during labor are common, but they are usually mild and necessitate treatment infrequently. However, even with the advent of newer low-dose epidurals, the extent of impaired motor ability remains variable across studies. The incidence of "walking" epidurals during labor is likely to be complicated by multiple factors, including individual patient desires, safety considerations, and hospital policies. In response to risks for a decrease in uterine contractions that could prolong labor, oxytocin augmentation is likely to be administered after epidural analgesia. The use of "delayed" pushing may be an effective way to minimize the risk for difficult deliveries. Upright positioning even when confined to bed may be advantageous and desirable to women; however, additional research to determine actual outcome benefits with epidurals is needed. Implications for further research linked to epidural analgesia also include informed consent, modification of caregiving procedures, and staffing/cost issues.

One-side riddled basin below and beyond the blowout bifurcation

NASA Astrophysics Data System (ADS)

Yang, H. L.

2000-10-01

In this Rapid Comunication we report a phenomenon of a one-side riddled basin where one side of the basin of attraction of an attractor on an invariant subspace (ISS) is globally riddled, while the other side is only locally riddled. This kind of basin appears due to the symmetry breaking with respect to the ISS. This one-side riddled basin can even persist beyond the blowout bifurcation, contrary to the previously reported riddled basins which exist only below the blowout transition. An experimental situation where this phenomenon can be expected is proposed.

Synthesis of uniformly distributed single- and double-sided zinc oxide (ZnO) nanocombs

Uniformly distributed single- and double-sided zinc oxide (ZnO) nanocomb structures have been prepared by a vapor-liquid-solid technique from a mixture of ZnO nanoparticles and graphene nanoplatelets. The ZnO seed nanoparticles were synthesized via a simple precipitation method. The structure of the ZnO nanocombs could easily be controlled by tuning the carrier-gas flow rate during growth. Higher flow rate resulted in the formation of uniformly-distributed single-sided comb structures with nanonail-shaped teeth, as a result of the self-catalysis effect of the catalytically active Zn-terminated polar (0001) surface. Lower gas flow rate was favorable for production of double-sided comb structures with the twomore » sets of teeth at an angle of similar to 110 degrees to each other along the comb ribbon, which was attributed to the formation of a bicrystal nanocomb ribbon. Lastly, the formation of such a double-sided structure with nanonail-shaped teeth has not previously been reported.« less

Is By-passing the Stomach a Means to Optimise Sodium Bicarbonate Supplementation? A Case-study With a Post-Bariatric Surgery Individual.

PubMed

de Oliveira, Luana Farias; Saunders, Bryan; Artioli, Guilherme Giannini

2018-05-03

Sodium bicarbonate (SB) is an ergogenic supplement shown to improve high-intensity exercise via increased blood bicarbonate buffering. Substantial amounts of the ingested bicarbonate are neutralised in the stomach. Bariatric surgery results in a small gastric pouch which dramatically reduces exposure time of any ingested food in the stomach. The aim of this study was to examine the pharmacokinetics of orally ingested SB in a post-gastric bypass individual to determine the magnitude of changes in blood bicarbonate and associated side-effects. We hypothesized that SB supplementation in a gastric bypass model would result in greater blood bicarbonate increases and less side-effects than in healthy individuals due to minimal bicarbonate losses in the stomach. One post-bariatric male ingested 0.3 g·kg -1 BM of SB on three occasions (SB1, SB2, SB3) and 0.3 g·kg -1 BM of placebo (PL) on a further occasion. Blood bicarbonate was determined before and every 10-min following supplement ingestion for 3 h and then every 20 min for a further 1 h. Side-effects were reported using an adapted questionnaire at identical time points. Maximal increases in blood bicarbonate with SB were +20.0, +15.2 and +12.6 mM, resulting in maximal bicarbonate concentrations of 42.8, 39.3 and 36.2 mM. Area under the curve was SB1: 8328, SB2: 7747, SB3: 7627 mM·min -1 and 6436 mM·min -1 for PL. Side-effects with SB were scarce. Maximal bicarbonate increases were well above those shown previously, with minimal side-effects, indicative of minimal neutralisation of bicarbonate in the stomach. The large increases in circulating bicarbonate and minimal side-effects experienced by our post-gastric surgery patient are indicative that minimising neutralisation of bicarbonate in the stomach, as would occur with enteric coated capsules, may optimise SB supplementation and thus warrants investigation.

A preliminary report on the effects of paclitaxel-impregnated stents on sheep nasal mucosa.

Traditional frontal sinus stents serve only as mechanical devices. It has been proposed that stents also may serve as drug-delivery systems for the topical application of drugs that minimize postoperative scarring. Paclitaxel (Taxol), which has recognized antiscarring effects, may be incorporated via a polymeric formulation into standard rubber stents. The impact of topically applied paclitaxel on the morphology of the nasal mucosa is unknown. An adult sheep model was used for this study. A modified rubber T-tube stent (incorporating paclitaxel at varying dosages) was secured to each side of the septum in four animals (eight sides). An unmodified T-tube was placed on each side of one animal, a T-tube with the drug carrier (but no paclitaxel) was placed on each side of the second animal, and T-tubes with varying paclitaxel were placed on each side of the final two animals. After 4 weeks, animals were killed and the nasal mucosa was harvested. The nasal mucosa was sectioned and stained with hematoxylin and eosin. A pathologist then assessed the nasal mucosa for vascular congestion, glandular atrophy, chronic inflammation, mucosal metaplasia, and mucosal ulceration. No consistent histopathological differences were noted in the specimens. All specimens showed varying degrees of vascular congestion, glandular atrophy, chronic inflammation, and mucosal metaplasia; the paclitaxel-impregnated stents were not consistently associated with more severe mucosal injury. Finally, mucosal ulceration was noted to be very rare in all specimens. This preliminary report describes the impact of paclitaxel-impregnated stents on sheep nasal mucosa, which tolerated these stents very well. Because paclitaxel minimizes scarring reactions at very low concentrations, paclitaxel-impregnated stents may prove useful in clinical situations in which frontal sinus stenting is deemed necessary. Additional investigations with animal models, as well as clinical trials, may be warranted.

Comparison of cost of immune globulin intravenous therapy to conventional immunosuppressive therapy in treating patients with autoimmune mucocutaneous blistering diseases.

PubMed

Daoud, Yassine J; Amin, Ketan G

2006-04-01

Autoimmune mucocutaneous blistering diseases (AMBD) are a group of potentially fatal diseases that affect the skin and mucous membranes. AMBD have different target antigens as well as variable clinical presentation, course, and prognosis. The mainstay of conventional immunosuppressive therapy (CIST) for AMBD is long-term high-dose systemic corticosteroids and immunosuppressive agents. Such therapy has proven effective in many patients; however, in some patients, the disease continues to progress with significant sequelae such as blindness, loss of voice, anal, and vaginal stenosis which causes poor quality of life. Furthermore, the CIST may have some serious side effects including opportunistic infections which may cause death. Immune globulin intravenous (IGIV) therapy has been reportedly used in the management of patients with AMBD refractory to CIST. IGIV has shown to be more clinically beneficial than CIST by bringing about long-term clinical remission and less recurrence. The high cost of the IGIV is of concern to patients, physicians, and insurance companies. In this report, we compare the cost of IGIV to that of CIST in treating a cohort of 15 mucous membrane pemphigoid (MMP), 10 ocular cicatricial pemphigoid (OCP), 15 bullous pemphigoid (BP), and 32 pemphigus vulgaris (PV) patients. In each cohort of patients, CIST had significant side effects, many of which were hazardous and required prolonged and frequent hospitalizations. Some of these side effects were severe enough to require discontinuation of the treatment. We consider the total cost of CIST to be the actual cost of the drug, plus the cost of management of the side effects produced by CIST. In the same patient cohort, no significant side effects to IGIV were observed. None of the IGIV treated patients required physician visits, laboratory tests, or hospitalizations specifically related to IGIV therapy. Hence, the total cost of the IGIV therapy is the actual cost of the IGIV only. The mean total cost of treatment of IGIV therapy is statistically significantly less than that of CIST during the entire course of the disease and on an annual basis. In conclusion, IGIV therapy is a safe, clinically beneficial, and a cost effective alternative treatment in patients with AMBD, non-responsive to CIST.

Sweating in other areas is common in secondary hyperhidrosis (after surgery or in specific clinical conditions). Oxybutynin has provided good results and is an alternative for treating hyperhidrosis at common sites. Our aim was to evaluate the efficacy of oxybutynin as a treatment for primary sweating at uncommon sites (e.g., the back and groin). METHODS: This retrospective study analyzed 20 patients (10 females) who received oxybutynin for primary focal hyperhidrosis at uncommon sites. The subjects were evaluated to determine quality of life before beginning oxybutynin and six weeks afterward and they were assigned grades (on a scale from 0 to 10) to measure their improvement at each site of excessive sweating after six weeks and at the last consult. RESULTS: The median follow-up time with oxybutynin was 385 days (133-1526 days). The most common sites were the back (n = 7) and groin (n = 5). After six weeks, the quality of life improved in 85% of the subjects. Dry mouth was very common and was reported by 16 patients, 12 of whom reported moderate/severe dry mouth. Five patients stopped treatment (two: unbearable dry mouth, two: excessive somnolence and one: palpitations). At the last visit, 80% of patients presented with moderate/great improvement at the main sites of sweating. CONCLUSION: After six weeks, more than 80% of the patients presented with improvements in their overall quality of life and at the most important site of sweating. Side effects were common (80% reported at least one side effect) and caused 25% of the patients to discontinue treatment. Oxybutynin is effective for treating bothersome hyperhidrosis, even at atypical locations and most patients cope well with the side effects. PMID:25318092

Oxcarbazepine is an antiepileptic drug that has been approved by the US FDA and is indicated for use as monotherapy or adjunctive therapy in the treatment of partial seizures in adults and children aged over 4 years. The aim of this report is to investigate the results of clinical trials in order to ascertain the efficacy and safety of oxcarbazepine for use in bipolar disorder and schizoaffective disorder. Oxcarbazepine is a keto-congener of carbamazepine with fewer side effects and drug interactions. Orally administrated oxcarbazepine is rapidly and completely absorbed and has a half-life of 9 h. Currently, there is a lack of controlled clinical trials studying the use of oxcarbazepine. In light of controlled and open-label prospective studies, it may be useful for manic symptoms in the treatment of bipolar and schizoaffective patients. Case reports, retrospective and prospective studies suggest that oxcarbazepine might have prophylactic efficacy and long-term benefit for these patients. In addition, owing to its lower propensity for drug interactions and side effects, it may be useful in the treatment of refractory patients with bipolar and schizoaffective disorder. However, most of the trials have relevant methodological shortcomings. The side-effect profile of oxcarbazepine is similar to carbamazepine, but the severity of these effects appears to be slightly less. The symptoms that are most frequently associated with the use of oxcarbazepine are asthenia, headache, dizziness, somnolence, nausea, diplopia and skin rash. Isolated cases of hyponatremic coma have been reported, thus electrolyte abnormalities should be closely monitored. Oxcarbazepine is now a generic drug, but the metabolite licarbazepine and other related compounds, such as eslicarbazepine, are currently being studied under controlled conditions and might become useful therapies for bipolar and schizoaffective disorder in the future.

Aripiprazole-Induced Hyperlipidemia: An Update.

Tarraf, Caroline; Naja, Wadih J

2016-08-25

To review the literature on the metabolic side effects of aripiprazole. Three cases of aripiprazole-induced hypertriglyceridemia are also presented. A search was conducted of English-language articles and abstracts (meta-analyses, randomized controlled trials, clinical trials, naturalistic open-label trials, reviews, and case reports) published up to August 31, 2014, in electronic databases (PubMed, MEDLINE). Free-text and MeSH search keywords included aripiprazole, cholesterol, triglyceride, lipid profile, hyperlipidemia, and hypercholesterolemia and their differing terminations and combinations. The search was supplemented by a manual review of reference lists from the identified publications. Pediatric studies were excluded. Twenty-two articles were found and 3 aspects of the metabolic side effects of aripiprazole were reviewed: (1) the prevalence of the metabolic syndrome in mentally ill patients prior to any antipsychotic use to highlight the initial predisposition of this group of patients to develop the metabolic syndrome, (2) the prevalence of metabolic changes depending on the choice of antipsychotic (aripiprazole compared to other antipsychotics), and (3) metabolic changes reported after switching from an antipsychotic to aripiprazole. Patients with mental disorders are at high risk for developing dyslipidemia, diabetes, and the full criteria of the metabolic syndrome. Antipsychotic use exacerbates this risk, thus increasing the mortality in this population. Nevertheless, it seems that the risk for these side effects varies with each antipsychotic. Although by and large the literature supports the supposition that aripiprazole causes less metabolic effects than other antipsychotics, we report 3 cases of serious aripiprazole-related dyslipidemia in young subjects. On the basis of these 3 cases, aripiprazole can cause hypertriglyceridemia. Triglyceride levels should be carefully monitored in patients with mental disorders taking aripiprazole. © Copyright 2016 Physicians Postgraduate Press, Inc.

Complications of extracorporeal shockwave therapy in plantar fasciitis: Systematic review.

Extracorporeal shockwave therapy (ESWT) seems to be an effective treatment for plantar fasciitis (PF) and is assumed to be safe. No systematic reviews have been published that specifically studied the complications and side effects of ESWT in treating PF. Aim of this systematic review is therefore to evaluate the complications and side effects of ESWT in order to determine whether ESWT is a safe treatment for PF. For this systematic review the databases PubMed, MEDLINE, Cochrane and Embase were used to search for relevant literature between 1 January 2005 and 1 January 2017. PRISMA guidelines were followed. Thirty-nine studies were included for this review, representing 2493 patients (2697 heels) who received between 6424 and 6497 ESWT treatment sessions, with an energy flux density between 0.01 mJ/mm 2 and 0.64 mJ/mm 2 and a frequency of 1000-3800 SWs. Average follow-up was 14.7 months (range: 24 h - 6 years). Two complications occurred: precordial pain and a superficial skin infection after regional anaesthesia. Accordingly, 225 patients reported pain during treatment and 247 reported transient red skin after treatment. Transient pain after treatment, dysesthesia, swelling, ecchymosis and/or petechiae, severe headache, bruising and a throbbing sensation were also reported. ESWT is likely a safe treatment for PF. No complications are expected at one-year follow-up. However, according to the current literature long-term complications are unknown. Better descriptions of treatment protocols, patient characteristics and registration of complications and side effects, especially pain during treatment, are recommended.

A Systematic Review of the Safety and Effect of Neurofeedback on Fatigue and Cognition.

PubMed

Luctkar-Flude, Marian; Groll, Dianne

2015-07-01

Many cancer survivors continue to experience ongoing symptoms, such as fatigue and cognitive impairment, which are poorly managed and have few effective, evidence-based treatment options. Neurofeedback is a noninvasive, drug-free form of brain training that may alleviate long-term symptoms reported by cancer patients. The purpose of this systematic review of the literature was to describe the effectiveness and safety of neurofeedback for managing fatigue and cognitive impairment. A systematic review of the literature was conducted using Joanna Briggs Institute (JBI) methodology. A comprehensive search of 5 databases was conducted: Medline, CINAHL, AMED, PsycInfo, and Embase. Randomized and nonrandomized controlled trials, controlled before and after studies, cohort, case control studies, and descriptive studies were included in this review. Twenty-seven relevant studies were included in the critical appraisals. The quality of most studies was poor to moderate based on the JBI critical appraisal checklists. Seventeen studies were deemed of sufficient quality to be included in the review: 10 experimental studies and 7 descriptive studies. Of these, only 2 were rated as high-quality studies and the remaining were rated as moderate quality. All 17 included studies reported positive results for at least one fatigue or cognitive outcome in a variety of populations, including 1 study with breast cancer survivors. Neurofeedback interventions were well tolerated with only 3 studies reporting any side effects. Despite issues with methodological quality, the overall positive findings and few reported side effects suggest neurofeedback could be helpful in alleviating fatigue and cognitive impairment. Currently, there is insufficient evidence that neurofeedback is an effective therapy for management of these symptoms in cancer survivors, however, these promising results support the need for further research with this patient population. More information about which neurofeedback technologies, approaches, and protocols could be successfully used with cancer survivors and with minimal side effects is needed. This research will have significance to nurses and physicians in oncology and primary care settings who provide follow-up care and counseling to cancer survivors experiencing debilitating symptoms in order to provide information and education related to evidence-based therapy options. © The Author(s) 2015.

Informing patients about medical treatments and their possible side effects is ethically and legally obligatory but may trigger negative expectations and nocebo-related side effects. This pilot study aims to investigate the effect of different informed consent procedures on treatment expectations for adjuvant breast cancer treatments (Study 1: endocrine therapy; Study 2: chemotherapy). Using an experimental 2-factorial design, healthy women were informed about endocrine therapy (n = 60) or chemotherapy (n = 64) within a hypothetical scenario. Information was framed with or without treatment benefit information and delivered in a personalized or standardized interaction. Primary outcomes were necessity-concern beliefs about the treatment and side-effect expectations, secondary outcomes were decisional conflicts. In Study 1, side-effect expectations (η²p= .08) and decisional conflicts (η²p = .07) were lower when framed treatment information was given. Providing personalized information resulted in more functional necessity-concern beliefs (η²p = .06) and lower decisional conflicts (η²p = .07). Personalizing and framing of information resulted in more functional necessity-concern beliefs (η²p = .10) and lower decisional conflicts. In Study 2, necessity-concern beliefs were more functional with framing (η²p = .06). Participants in the personalized groups reported lower decisional conflicts (η²p = .06). No differences in side-effect expectations were revealed. This is the first study to provide evidence for optimized treatment expectations through altered informed consent strategies. The results emphasize that framing and personalizing informed consent can positively influence treatment expectations and reduce decisional conflicts. However, generalizations are impaired by the study's pilot character. The potential to prevent nocebo responses in clinical practice should be analyzed.

Primary axillary hyperhidrosis (PAH) creates social stress in patients. Although there are several options for treating PAH, only surgical modalities have conferred a permanent solution. This study evaluated the clinical effectiveness of fractionated microneedle radiofrequency (FMR) treatment for PAH. This study is based on a single-blind, sham control comparative design. In all, 25 patients with severe PAH underwent three sessions of FMR at 3-week intervals. One side was treated with FMR while the other was sham controlled. Efficacy was evaluated using the hyperhidrosis disease severity scale (HDSS), sweating intensity visual analogue scale (VAS) and patient satisfaction at baseline, 3 weeks after each session and at 3 months after the last. Skin biopsies were obtained from two enrolled patients. The HDSS and VAS demonstrated significant improvement after treatment on the treated side in comparison with the control side. The mean ± SD of the HDSS after 21 weeks were 1.87 ± 0.61 and 3.38 ± 0.49 (P < 0.001) for the treated and the controlled side, respectively. The follow-up evaluation revealed that 79% of the patients showed a 1 or 2-score decrease in HDSS. In total, 80% of patients reported more than 50% satisfaction at the end of the study. Histopathological findings showed a decrease of the number of the sweat glands in the treated side, confirming the above findings. Treatment of PAH with FMR as a non-invasive modality can be a safe option with positive therapeutic effects on HDSS without any long-lasting side effects. © 2014 The Australasian College of Dermatologists.

EXERCISE IMPROVES SEXUAL FUNCTION IN WOMEN TAKING ANTIDEPRESSANTS: RESULTS FROM A RANDOMIZED CROSSOVER TRIAL

2014-01-01

Background In laboratory studies, exercise immediately before sexual stimuli improved sexual arousal of women taking antidepressants [1]. We evaluated if exercise improves sexual desire, orgasm, and global sexual functioning in women experiencing antidepressant-induced sexual side effects. Methods Fifty-two women who were reporting antidepressant sexual side effects were followed for 3 weeks of sexual activity only. They were randomized to complete either three weeks of exercise immediately before sexual activity (3×/week) or 3 weeks of exercise separate from sexual activity (3×/week). At the end of the first exercise arm, participants crossed to the other. We measured sexual functioning, sexual satisfaction, depression, and physical health. Results Exercise immediately prior to sexual activity significantly improved sexual desire and, for women with sexual dysfunction at baseline, global sexual function. Scheduling regular sexual activity significantly improved orgasm function; exercise did not increase this benefit. Neither regular sexual activity nor exercise significantly changed sexual satisfaction. Conclusions Scheduling regular sexual activity and exercise may be an effective tool for the behavioral management of sexual side effects of antidepressants. PMID:24754044

Human nutritional requirements are summarized, including recommended daily intake and maximum safe chronic intake of nutrients. The biomedical literature on various types of chemically defined diets (CDD's), which are liquid, formulated diets for enteral and total parenteral nutrition, is reviewed. The chemical forms of the nutrients in CDD's are detailed, and the compositions and sources of representative commercial CDD's are tabulated. Reported effects of CDD's in medical patients, healthy volunteers, and laboratory animals are discussed. The effects include gastrointestinal side effects, metabolic imbalances, nutrient deficiencies and excesses, and psychological problems. Dietary factors contributing to the side effects are examined. Certain human nutrient requirements have been specified more precisely as a result of long-term use of CDD's, and related studies are included. CDD's are the most restricted yet nutritionally complete diets available.

Life-threatening complications of ibogaine: three case reports.

Ibogaine is a naturally occurring psychoactive alkaloid extracted from the roots of the Tabernanthe iboga plant, which in alternative medicine is used to treat drug dependency. However, this upcoming, online advocated therapy can be dangerous due to its potentially lethal adverse effects. We present three cases in which toxic side effects were noted. We used the Naranjo scale to estimate the probability of a causal relationship between these effects and ibogaine. Findings in these three cases are suggestive of a causal relationship between the use of ibogaine and serious respiratory and cardiac problems (including lengthening of the QT interval). In our opinion it is of great importance that clinicians are aware of these potentially serious side effects and realise that widespread online marketing practices will give many more people access to ibogaine.

Gabapentin has been shown to reduce pain associated with diabetic neuropathia and postherpetic neuralgia. To date it is not known, whether gabapentin is generally effective in other types of pain. It was therefore the aim to study gabapentin in patients suffering from intractable pain with respect to efficacy, predictive factors and side effects. Retrospective analysis of the data sheet of pretreated patients suffering from intractable pain and treated with gabapentin as a third line drug at a university pain clinic. Pain intensity (visual analogue scale, VAS 0 -10 cm), pain characteristics, diagnosis, pre- and co-treatment, and side effects were assessed. Response to treatment was defined as a 50% reduction in pain or a pain intensity of VAS

Daikenchuto (DKT) has a stimulant effect on intestinal motility and reportedly has a positive effect on postoperative intestinal motility in patients with sigmoid colon cancer. In this study, we investigated the effects of DKT in patients with right-side colon cancer. This retrospective study included 88 patients with right-side colon cancer. We orally administered 7.5 g of DKT in the DKT group and did not administer any DKT to patients in the no-DKT group. All patients ingested radiopaque markers 2 h before surgery, which were used to assess intestinal motility. The postoperative intestinal motility was radiologically assessed by counting the numbers of residual markers in the large and small intestines. The DKT and no-DKT groups showed no marked differences in the total number of residual markers or number of residual markers in the small intestine. However, in the elderly subgroup, the total number of residual markers in the DKT group was significantly less than in the no-DKT group. Although DKT had some small effect on the postoperative intestinal motility for most patients, it may have positive effects in elderly patients.

1974-01-01

A comparison has been made of the effect of three volatile-removing techniques during molding on the properties of phenolic-fiber composites. The first technique involved heating the molding compound from one side, initiating the volatile-producing reactions, and driving these volatiles through the compound toward the cooler side. The second technique involved the application of a vacuum to the molding cavity before and during the cure cycle. The third technique was a combination of the first two. These techniques were used in the compression molding of phenolic-asbestos and phenolic-glass composites. The effects of both the individual and combined techniques on the mechanical, thermal, and sorption properties of the composites are reported.

Drug therapy is the mainstay of treatment for overactive bladder (OAB), but antimuscarinic agents possess side-effects. These side-effects decrease the patients' quality of life. We therefore assessed the impact of side-effects on health-related quality of life (HR-QoL) through an analysis of EQ-5D questionnaire. This study was designed to investigate the patients' satisfaction by quality weight of health status as affected by the side-effects of OAB medications. Patients who had OAB symptoms lasting longer than 3 months and have experienced side-effects after any antimuscarinic treatments filled in the EQ-5D questionnaire. The enrolled patients had two EQ-5D questionnaires for two different health statuses, i.e., presence or absence of side-effects. Quality weight was calculated using the ED-5D health status score with Korean tariff. One hundred patients were enrolled and completed the HR-QoL questionnaire. The most prevalent side-effect was dry mouth (61%) and 28% patients had dry mouth and constipation concurrently. Most of the patients with side-effects tried to endure and overcome these side-effects (79%), but 10% desired a change in medication, and 6% stopped medication altogether. The quality weight of EQ-5D without side-effects was 0.863, while the quality weight with side-effects was 0.666 (P < 0.001). The VAS score was 79 in patient without side-effects and 57 in those with side-effects, supporting the results of quality weight assessment. Overactive bladder patients may enjoy a better quality of life if side-effects associated with antimuscarinic therapy are fewer. © 2016 John Wiley & Sons Australia, Ltd.

We studied the evolution of the patient-provider relationship (PPR) in HIV-infected patients who reported trustful relationships at highly active antiretroviral therapy (HAART) treatment initiation. Psychosocial and clinical data were obtained from the French ANRS CO-8 cohort. Break of trust was defined using the question "How much do you trust the provider who usually treats you at this clinic?" Predictors of a possible break of trust during the 5 years after initiating treatment for those patients reporting a trustful PPR at month 0 were identified using a Cox model. During a total follow-up of 3,044 person-years, 68 (7%) patients reported having at least 1 break of trust in their PPR. Break of trust is independently associated with younger age, dissatisfaction with medical staff's explanations, cigarette smoking, and self-reported side effects and is independently inversely associated with severe HIV-related events and changes of treatment. A patient's break of trust in his provider is relatively infrequent. Accounting for the influence of immunologic status and psychosocial factors, self-reported side effects are shown to be detrimental to the PPR. Interestingly, clinical events and changes of treatment prevent a possible break of trust by reinforcing the provider's role. These results underline the importance of recognizing a patient's perceived secondary effects and developing appropriate care.

Acute encephalitis with refractory, repetitive partial seizures (AERRPS) is characterized by repetitive seizures during the acute and chronic phases and has a poor neurological outcome. Burst-suppression coma via continuous i.v. infusion of a short-acting barbiturate is used to terminate refractory seizures, but the severe side-effects of short-acting barbiturates are problematic. We report on a 9-year-old boy with AERRPS who was effectively treated with very-high-dose phenobarbital (VHDPB) combined with intermittent short-acting barbiturates. VHDPB side-effects were mild, especially compared with those associated with continuous i.v. infusion of short-acting barbiturates (dosage, 40-75 mg/kg/day; maximum blood level, 290 μg/mL). Using VHDPB as the main treatment, short-acting barbiturates were used intermittently and in small amounts. This is the first report to show that VHDPB, combined with intermittent short-acting barbiturates, can effectively treat AERRPS. After treatment, convulsions were suppressed and daily life continued, but intellectual impairment and high-level dysfunction remained. © 2016 Japan Pediatric Society.

When 1+1=1: the unification of independent actors revealed through joint Simon effects in crossed and uncrossed effector conditions.

PubMed

Welsh, Timothy N

2009-12-01

The "Simon effect" describes a pattern of reaction times (RTs) where responses to symbolic information are shorter when the information is presented on the same side of space as the desired response than when it is on the opposite side of space. For example, if right hand responses are required for green targets and left hand responses for red targets, RTs with the right hand are shorter when the green target appears on the right side than on the left side. It has been reported that Simon effects also appear when two individuals perform independent components of a Simon effect task. It has been suggested that such joint Simon effects occur because participants represent the action of their partner. It is unclear, however, if the joint Simon effect emerges because: (1) each partner represents the other's action; (2) each partner is using the other person or their response as an environmental reference; or (3) an intra-hemispheric processing advantage due to the lateralized cerebral organization of perceptual and motor systems. The present study distinguished between these possibilities by asking pairs of participants to perform in conditions in which they crossed their arms into the other person's space. Consistent with within-person Simon effects, joint Simon effects were observed in uncrossed- and crossed limb conditions. These results support a response co-representation explanation of joint Simon effects. It is suggested that the processes underlying the evoked representations have developed to allow two independent agents to form temporary synergies to facilitate efficient task completion. 2009 Elsevier B.V.

2011-01-01

The authors describe the theories of pathogenesis for capillary hemangioma and discuss the benefits and side effects of current treatment options, such as systemic and intralesional corticosteroids, laser therapy, and surgical excision. They also evaluate the recent systemic and topical applications of beta-blockers to treat infantile hemangioma. Although no major adverse events from beta-blocker treatment have been reported, the incidence of potential side effects such as bronchospasm, hypoglycemia, heart block, bradycardia, and congestive heart failure is unknown due to the novelty of the treatment. It has been postulated that topical application for localized superficial tumor may reduce systemic effects. Further research is necessary to compare the effectiveness of different treatments and to find the optimal dosing and delivery methods to minimize adverse effects in the treatment of this disorder.

This is the eleventh in a series of TOPEX Radar Engineering Assessment Reports, The initial TOPEX Radar Altimeter Engineering Assessment Report, in February 1994, presented performance results for the NASA Radar Altimeter on the TOPEX/POSEIDON spacecraft, from the time of its launch in August 1992 to February 1994. Since the time of that initial report and prior to this report, there have been nine interim supplemental Engineering Assessment Reports, issued in March 1995, May 1996, March 1997, June 1998, August 1999, September 2000, June 2001, March 2002 and again in May 2003.The sixth supplement in September 2000 was the first assessment report that addressed Side B performance, and presented the altimeter performance from the turn-on of Side B until the end of calendar year 1999. This report extends the performance assessment of Side B to the end of calendar year 2003 and includes the performance assessment of Jason-1, the TOPEX follow-on mission, launched on December 7, 2001.

Movement Disorders Induced by the "Atypical" Antipsychotic Aripiprazole.

Selfani, Karim; Soland, Valérie L; Chouinard, Sylvain; Huot, Philippe

2017-01-01

Aripiprazole is an antipsychotic that acts as a partial agonist at dopamine D2 receptors. Because of its partial agonist activity, it was believed that aripiprazole would be less susceptible than typical antipsychotics to induce extrapyramidal side effects. However, a few case-reports and case-series detailing aripiprazole-induced movement disorders have been published, suggesting that aripiprazole-induced movement disorders may arise. Here, we seek to report further cases of aripiprazole-induced movement disorders to raise the awareness of clinicians on this adverse effect. Patients referred to the André-Barbeau Movement Disorder clinic treated with aripiprazole were enrolled in this study. Their charts were retrospectively reviewed and data regarding past psychiatric history, past antipsychotic medication, duration of aripiprazole treatment, daily dose of aripiprazole administered, and resulting movement disorders were collected. We report 14 cases of parkinsonism, tardive dyskinesia and akathisia induced by aripiprazole. Some of these, mostly the parkinsonian phenotype, abated spontaneously following drug discontinuation, whereas others, mostly related to tardive phenomena, persisted after aripiprazole was discontinued, and required treatment. This case-series adds to the existing literature that suggests that movement disorders may arise following treatment with aripiprazole. Clinicians should be aware of this potential side effect when prescribing aripiprazole to patients.

Patient positioning and ventilator-associated pneumonia.

PubMed

Hess, Dean R

2005-07-01

Rotational beds, prone position, and semi-recumbent position have been proposed as procedures to prevent ventilator-associated pneumonia (VAP). Rotational therapy uses a special bed designed to turn continuously, or nearly continuously, the patient from side to side; specific designs include kinetic therapy and continuous lateral rotation therapy. A meta-analysis of studies evaluating the effect of rotational bed therapy shows a decrease in the risk of pneumonia but no effect on mortality. Two studies reported a lower risk of VAP in patients placed in a prone position, with no effect on mortality. Studies using radiolabeled enteral feeding solutions in mechanically ventilated patients have reported that aspiration of gastric contents occurs to a greater degree when patients are in the supine position, compared with the semirecumbent position. One study reported a lower rate of VAP in patients randomized to semi-recumbent compared to supine position. Although each of the techniques discussed in this paper has been shown to reduce the risk of VAP, none has been shown to affect mortality. The available evidence suggests that semi-recumbent position should be used routinely, rotational therapy should be considered in selected patients, and prone position should not be used as a technique to reduce the risk of VAP.

Deep brain stimulation (DBS) of the subthalamic nucleus is an effective treatment for advanced Parkinson disease (PD). However, achieving ideal outcomes by conventional programming can be difficult in some patients, resulting in suboptimal control of PD symptoms and stimulation-induced adverse effects. Interleaving stimulation (ILS) is a newer programming technique that can individually optimize the stimulation area, thereby improving control of PD symptoms while alleviating stimulation-induced side effects after conventional programming fails to achieve the desired results. We retrospectively reviewed PD patients who received DBS programming during the previous 4 years in our hospital. We collected clinical and demographic data from 12 patients who received ILS because of incomplete alleviation of PD symptoms or stimulation-induced adverse effects after conventional programming had proven ineffective or intolerable. Appropriate lead location was confirmed with postoperative reconstruction images. The rationale and clinical efficacy of ILS was analyzed. We divided our patients into 4 groups based on the following symptoms: stimulation-induced dysarthria and choreoathetoid dyskinesias, gait disturbance, and incomplete control of parkinsonism. After treatment with ILS, patients showed satisfactory improvement in PD symptoms and alleviation of stimulation-induced side effects, with a mean improvement in Unified PD Rating Scale motor scores of 26.9%. ILS is a newer choice and effective programming strategy to maximize symptom control in PD while decreasing stimulation-induced adverse effects when conventional programming fails to achieve satisfactory outcome. However, we should keep in mind that most DBS patients are routinely treated with conventional stimulation and that not all patients benefit from ILS. ILS is not recommended as the first choice of programming, and it is recommended only when patients have unsatisfactory control of PD symptoms or stimulation-induced side effects after multiple treatments with conventional stimulation. A return to conventional stimulation may be required if ILS induces new side effects or the needs of the patient change.

The common cold is one of the most common illnesses in humans and constitutes an economic burden both in terms of productivity and expenditure for treatment. There is no proven cure for the common cold and symptomatic relief is the mainstay of treatment. The use of intranasal ipratropium bromide (IB) has been addressed in several studies and might prove an effective treatment for the common cold. To determine the effect of IB versus placebo or no treatment on severity of rhinorrhoea and nasal congestion in children and adults with the common cold. Subjective overall improvement was another primary outcome and side effects (for example, dry mucous membranes, epistaxis and systemic anticholinergic effects) were reported as a secondary outcome. In this updated review we searched CENTRAL 2013, Issue 3, MEDLINE (1950 to March week 4, 2013), MEDLINE in-process and other non-indexed citations (8 April 2013), EMBASE (1974 to April 2013), AMED (1985 to April 2013), Biosis (1974 to February 2011) and LILACS (1985 to April 2013). Randomised controlled trials (RCTs) comparing IB to placebo or no treatment in children and adults with the common cold. Two review authors independently extracted data and assessed trial quality. We used a standardised form to extract relevant data and we contacted trial authors for additional information. Seven trials with a total of 2144 participants were included. Four studies (1959 participants) addressed subjective change in severity of rhinorrhoea. All studies were consistent in reporting statistically significant changes in favour of IB. Nasal congestion was reported in four studies and was found to have no significant change between the two groups. Two studies found a positive response in the IB group for the global assessment of overall improvement. Side effects were more frequent in the IB group, odds ratio (OR) 2.09 (95% confidence interval (CI) 1.40 to 3.11). Commonly encountered side effects included nasal dryness, blood tinged mucus and epistaxis. The overall risk of bias in the included studies was moderate. For people with the common cold, the existing evidence, which has some limitations, suggests that IB is likely to be effective in ameliorating rhinorrhoea. IB had no effect on nasal congestion and its use was associated with more side effects compared to placebo or no treatment although these appeared to be well tolerated and self limiting. There is a need for larger, high-quality trials to determine the effectiveness of IB in relieving common cold symptoms.

This study examines the subjective acceptance during UHF-CMR in a cohort of healthy volunteers who underwent a cardiac MR examination at 7.0T. Within a period of two-and-a-half years (January 2012 to June 2014) a total of 165 healthy volunteers (41 female, 124 male) without any known history of cardiac disease underwent UHF-CMR. For the assessment of the subjective acceptance a questionnaire was used to examine the participants experience prior, during and after the UHF-CMR examination. For this purpose, subjects were asked to respond to the questionnaire in an exit interview held immediately after the completion of the UHF-CMR examination under supervision of a study nurse to ensure accurate understanding of the questions. All questions were answered with "yes" or "no" including space for additional comments. Transient muscular contraction was documented in 12.7% of the questionnaires. Muscular contraction was reported to occur only during periods of scanning with the magnetic field gradients being rapidly switched. Dizziness during the study was reported by 12.7% of the subjects. Taste of metal was reported by 10.1% of the study population. Light flashes were reported by 3.6% of the entire cohort. 13% of the subjects reported side effects/observations which were not explicitly listed in the questionnaire but covered by the question about other side effects. No severe side effects as vomiting or syncope after scanning occurred. No increase in heart rate was observed during the UHF-CMR exam versus the baseline clinical examination. This study adds to the literature by detailing the subjective acceptance of cardiovascular magnetic resonance imaging examinations at a magnetic field strength of 7.0T. Cardiac MR examinations at 7.0T are well tolerated by healthy subjects. Broader observational and multi-center studies including patient cohorts with cardiac diseases are required to gain further insights into the subjective acceptance of UHF-CMR examinations.

The use of skin fairness products that frequently contain toxic ingredients is associated with significant adverse health side effects. Due to the high prevalence of use in Asian and African countries, skin fairness product use is recognized as a growing public health concern. The multi-million-dollar skin fairness product industry has also been criticized for perpetuating racism and social inequalities by reinforcing beliefs about the benefits of skin fairness for cultural capital. No quantitative studies have assessed people’s beliefs about fairness and reasons for using or not using these products in India, one of the largest global markets for skin fairness products. The current study explored skin fairness product use among 1,992 women and men aged 16–60 years in the city of Mumbai, India using a self-report questionnaire. A total of 37.6% of the sample reported currently using skin fairness products, with women being two times more likely to use these products. Among current users, 17% reported past experiences of adverse side effects, and “Media/TV/Adverts” were the most common prompts for using fairness products, followed by “Friends” and “Family.” Men were significantly more likely than women to endorse beliefs about fairness being more attractive and were more likely to perceive family and peers as viewing fairness as beneficial for cultural capital. There were no differences between women and men currently using products in their desire to look as fair as media celebrities. Among non-users, women were significantly more likely than men to report concerns about product efficacy and side effects as reasons for non-use, while men were significantly more likely to report socioeconomic reasons for non-use. Implications of these findings are discussed in light of growing public health concerns about the use of fairness products, and potential for advocacy and public health interventions to address the use of skin fairness products.

Objective Many laypeople demonstrate excessive sensitivity to negative side effects of medical treatments, which may lead them to refuse beneficial therapies. This Internet-based experiment investigated three possible explanations for such “side effect aversion.” One was derived from mental accounting, one examined the mere presence of a side effect, and one focused on computational difficulties. Design Participants (N = 5,379) were presented with a hypothetical cancer preventive treatment situation that was or was not accompanied by one or two small side effects. The side effects were either beneficial or harmful. In all conditions the net absolute risk reduction associated with the treatment was 15%. Main Outcome Measures Participants indicated their willingness to accept treatment and their perceptions of the treatment’s effects on their overall cancer risk. Results Data were consistent only with the “mere presence” explanation of side effect aversion, the idea that side effects act as a strong negative cue that directly affects treatment appraisal. The number of negative side effects did not influence treatment willingness. Conclusion Side effect aversion is a challenge to informed decision making. Specific mechanisms that produce side effect aversion should be identified. PMID:19290712

Investigation of patients' subjective perspective regarding the effectiveness - as opposed to efficacy - of antipsychotic medication has been hampered by a relative shortage of self-report measures of global clinical outcome. This paper presents data supporting the feasibility, inter-item consistency, and construct validity of the Patient Assessment Questionnaire (PAQ)-a self-report measure of psychiatric symptoms, medication side effects and general wellbeing, ultimately intended to assess effectiveness of interventions for schizophrenia-spectrum patients. The original 53-item instrument was developed by a multidisciplinary team which utilized brainstorming sessions for item generation and content analysis, patient focus groups, and expert panel reviews. This instrument and additional validation measures were administered, via Audio Computer-Assisted Self-Interviewing (ACASI), to 300 stable, medicated outpatients diagnosed with schizophrenia or schizoaffective disorder. Item elimination was based on psychometric properties and Item-Response Theory information functions and characteristic curves. Exploratory factor analysis of the resulting 40-item scale yielded a five factor solution. The five subscales (General Distress, Side Effects, Psychotic Symptoms, Cognitive Symptoms, Sleep) showed robust convergent (β's=0.34-0.75, average β=0.49) and discriminant validity. The PAQ demonstrates feasibility, reliability, and construct validity as a self-report measure of multiple domains pertinent to effectiveness. Future research needs to establish the PAQ's sensitivity to change. Copyright © 2012 Elsevier Ireland Ltd. All rights reserved.

Vertical axis wind rotors: Status and potential. [energy conversion efficiency and aerodynamic characteristics

NASA Technical Reports Server (NTRS)

Vance, W.

1973-01-01

The design and application of a vertical axis wind rotor is reported that operates as a two stage turbine wherein the wind impinging on the concave side is circulated through the center of the rotor to the back of the convex side, thus decreasing what might otherwise be a high negative pressure region. Successful applications of this wind rotor to water pumps, ship propulsion, and building ventilators are reported. Also shown is the feasibility of using the energy in ocean waves to drive the rotor. An analysis of the impact of rotor aspect ratio on rotor acceleration shows that the amount of venting between rotor vanes has a very significant effect on rotor speed for a given wind speed.

The Effects of Cell Phone Conversations on the Attention and Memory of Bystanders

The pervasive use of cell phones impacts many people–both cell phone users and bystanders exposed to conversations. This study examined the effects of overhearing a one-sided (cell phone) conversation versus a two-sided conversation on attention and memory. In our realistic design, participants were led to believe they were participating in a study examining the relationship between anagrams and reading comprehension. While the participant was completing an anagram task, the researcher left the room and participants overheard a scripted conversation, either two confederates talking with each other or one confederate talking on a cell phone. Upon the researcher’s return, the participant took a recognition memory task with words from the conversation, and completed a questionnaire measuring the distracting nature of the conversation. Participants who overheard the one-sided conversation rated the conversation as significantly higher in distractibility than those who overheard the two-sided conversation. Also, participants in the one-sided condition scored higher on the recognition task. In particular they were more confident and accurate in their responses to words from the conversation than participants in the two-sided condition. However, participants’ scores on the anagram task were not significantly different between conditions. As in real world situations, individual participants could pay varying amounts of attention to the conversation since they were not explicitly instructed to ignore it. Even though the conversation was irrelevant to the anagram task and contained less words and noise, one-sided conversations still impacted participants’ self-reported distractibility and memory, thus showing people are more attentive to cell phone conversations than two-sided conversations. Cell phone conversations may be a common source of distraction causing negative consequences in workplace environments and other public places. PMID:23516514

Sexual side effects associated with conventional and atypical antipsychotics.

PubMed

Compton, M T; Miller, A H

2001-01-01

The sexual side effects of psychotropic medications are becoming increasingly recognized in clinical psychiatry. The magnitude of the problem of sexual side effects associated with antipsychotic medications has yet to be fully elucidated, but a multitude of references in the literature demonstrate the importance of these side effects in both men and women. All currently used antipsychotic medications are associated with sexual side effects of various types. Although each antipsychotic medication may have a specific side effect profile determined by its various receptor affinities and by the degree to which it elevates serum prolactin, there is currently no evidence that specific side effects can be predicted. Sexual side effects can be categorized according to the phase of the sexual response cycle with which they interfere. Suggestions for clinical evaluation and treatment options are provided, including risk factor modification, dose reduction, switching agents, and addition of other agents. Sexual side effects associated with conventional and atypical antipsychotic medications represent an underestimated and understudied set of side effects that may diminish a patient's quality of life and lead to treatment noncompliance. Clinicians prescribing antipsychotic medications should be familiar with the classification, evaluation, and treatment of these side effects.

Anxiety is a commonly reported side-effect of psychostimulant treatment. Our goal was to quantify the risk of anxiety as a side effect of psychostimulant treatment for attention-deficit/hyperactivity disorder (ADHD). We conducted a PubMed search to identify all double-blind, randomized, placebo-controlled trials examining the efficacy of psychostimulant medications in the treatment of children with ADHD. We used a fixed-effects meta-analysis to examine the risk ratio of anxiety reported as a side effect in children treated with psychostimulants compared with those treated with placebo. We used stratified subgroup analysis and meta-regression to examine the effects of stimulant type, dosage, duration of use, and trial design on the measured risk of anxiety. We identified 23 studies involving 2959 children with ADHD for inclusion in our meta-analysis. The risk of anxiety associated with psychostimulant treatment was significantly lower than that experienced with placebo (relative risk [RR] = 0.86 [95% CI: 0.77, 0.95], z = -2.90, p < 0.05). Higher doses of psychostimulants were associated with a reduced measured risk of anxiety of psychostimulants when compared with placebo (β = -0.0039 [95% CI: -0.00718, -0.00064], z = -2.34, p = 0.019). Meta-analysis suggests that treatment with psychostimulants significantly reduced the risk of anxiety when compared with placebo. This finding does not rule out the possibility that some children experience increased anxiety when treated with psychostimulants, but suggests that those risks are outweighed by the number of children who experience improvement in anxiety symptoms (possibly as a secondary effect of improved control of ADHD symptoms). Clinicians should consider rechallenging children with ADHD who report new-onset or worsening anxiety with psychostimulants, as these symptoms are much more likely to be coincidental rather than caused by psychostimulants.

Beneficial Effects of Palmitoylethanolamide on Expressive Language, Cognition, and Behaviors in Autism: A Report of Two Cases.

PubMed

Antonucci, Nicola; Cirillo, Alessandra; Siniscalco, Dario

2015-01-01

Introduction. Autism spectrum disorders are defined by behavioral and language atypias. Growing body of evidence indicates inflammatory mediators may contribute to the condition. Palmitoylethanolamide (PEA) is naturally occurring and has been available as a nonprescription medical food supplement in Europe since 2008. PEA has been tested in thousands of human subjects without any noted significant side effects. Here we report the first cases of the administration of PEA to two children with autism. Case Presentations. The first 13-year-old male child (Subject 1) presented with a total IgE of 572 IU/mL (nl < 200) and with low mature CD57(+) natural killer cell counts (32 cells/µL; nl = 60-300 cells/µL) and with significant eczema and allergic stigmata. Expressive language, as measured by mean length of utterance, and overall autism severity as measured by the Childhood Autism Rating Scale, Second Edition, improved significantly. Atopic symptoms diminished. No side effects were reported. The second male child, age 15 (Subject 2), also displayed noticeable and rapid improvements in cognitive, behaviors, and sociability. Conclusion. Currently, there is no definitive treatment for autism condition. Palmitoylethanolamide could be an effective treatment for autism syndrome. We propose appropriate double-blind clinical trials to further explore palmitoylethanolamide efficacy and safety.

[Atypical antipsychotics and sexual dysfunction: five case-reports associated with risperidone].

PubMed

Haefliger, T; Bonsack, C

2006-01-01

Sexual and reproductive function side effects of atypical antipsychotics are frequent, often underestimated and badly tolerated. They contribute to the 50% rate of non-compliance reported for treated patients. Prevalence of sexual dysfunction associated with atypical antipsychotic treatment is high, varying from 18 to 96%. Atypical antipsychotics aren't, as a group, much better than typical antipsychotics, and among them, risperidone seems to induce more and quetiapine less sexual dysfunction. Most atypicals are non-selective, and have actions on multiple central and peripheral receptors. Among these, dopaminergic blockade could have a direct - altering motivation (desire) and reward (orgasm) - and an indirect negative influence on sexuality. Actually, the secondary hyperprolactinemia induced by some antipsychotics (typical antipsychotics, risperidone and amisulpiride), is dose-dependent, more pronounced for female patients, and may have a detrimental effect on sexual function. It also may result in hypogonadism, particularly for female patients. The long-term consequences of this secondary hypogonadism are subject to debate but potentially severe. Furthermore, the blocking and/or modulating actions of atypical antipsychotics on adrenaline, serotonine, histamine or acetyl-choline receptors all have the potential to contribute to secondary sexual problems. The pharmacological profile of risperidone, characterized by a strong affinity for D2 and alpha1 receptors, correlates with his tendency to significantly elevate prolactin levels and to produce ejaculatory disturbances. FIVE CASE-REPORTS: We describe five case-reports of sexual or hormonal disturbances associated with risperidone treatment: two cases of ejaculatory disturbance, one case of galactorrhea and two cases of amenorrhea. Alberto and David are two young male schizophrenic patients, treated with risperidone, and complaining of a total absence of ejaculation despite a preserved orgasm. Many recent case-reports describe the occurrence of retrograde ejaculation associated with risperidone but the exact prevalence is unknown. Retrograde ejaculation is thought to be related to the strong adrenolytic activity of risperidone. Alberto refused his medication because the ejaculatory dysfunction was unbearable for him. A switch to haloperidol depot was eventually well tolerated, without any sexual complaints. His case emphasizes the importance of sexual function for self-esteem and how this may amplify the intolerance to side-effects. David is on depot-risperidone in a setting of a legally forced treatment. Though he - reluctantly - accepts his medication, this side effect exacerbates his pre-existing delusions, strongly focused on sexual themes. His case illustrates how intolerance to sexual side-effects may be amplified by nature of delusions. Mireille is a 58 year old psychotic female patient, whose 2 mg risperidone treatment produced a unilateral galactorrhea. This sign became problematic because potentially visible at a time when Mireille started an activity in a sheltered occupation in town. Lowering dosage of antipsychotic allowed disappearance of the problem. Subjective responses to galactorrhea have been reported to be highly individual. Apart being a potentially visible side-effect, it may be misinterpreted as evidence of pregnancy or of a tumoral process. The cases of Ermina and Denise illustrate two contrasted situations in terms of subjective tolerability of reproductive function side-effects. Both were pre-menopausal patients with hyperprolactinemia secondary to risperidone treatment, resulting in amenorrhea. This was unbearable for Ermina. A switch to olanzapine allowed, one month later, the menses to resume. For Denise, on the other hand, the amenorrhea was a positive event, freeing her of unpleasant menses. Amenorrhea occurs in about 30% of pre-menopausal women treated with risperidone. It is a consequence of hyperprolactinemia, which, although often silent, is not devoid of potential negative consequences (ie increased risk of osteoporosis or neoplasia, worsening of psychopathology) (34). When hyperprolactinemia is symptomatic, lowering of the dose of the antipsychotic, or switching to a prolactin-sparing agent (olanzapine, quetiapine, aripiprazole and clozapine) is recommended. Before this, women with amenorrhea secondary to antipsychotic-induced hyperprolactinemia should be advised that menses may resume. Especially after long-standing amenorrhea they may assume being menopaused, hence may believe birth control measures are no longer required. The prevalence of antipsychotic-induced sexual and reproductive function side-effects is high. Clinicians should be aware of them, because they are often badly tolerated, are associated with a low satisfaction and may therefore result in low adherence with treatment. This implies for the clinician to overtly discuss with the patient of his sexuality and the potential negative impact of antipsychotic treatment on it. The recognition of these problems allows the searching together for a solution. The described cases indicate that solving the problem is often possible, provided that individual preferences and subjective impact are taken in account. Antipsychotic treatment is often prescribed for very long periods. A better knowledge of - and attention to - the associated side effects, particularly on the sexual and reproductive functions, is necessary in order to reduce some potentially negative long-term effects and to improve the adherence to treatment of our patients.

Apium graveolens is one of the well-known herbs used for the treatment of different; however, allergic reactions have been reported after its use. This report aimed to demonstrate the A. graveolens induced hyperthyroidism after its oral consumption for weight loss. Mr. A, 48-year-old, with no history of any thyroid diseases, was diagnosed with hyperthyroidism due to daily consumption of 4 g of dried celery leaves for 45 days. After cessation of consumption and treatment with methimazole, the symptoms remitted. Then, the medication was discontinued when the lab tests and ultrasound were normal and indicated the patient's definite recovery. In 2 months follow up of, he was normal and thyroid-stimulating hormone (TSH), T4, T3, anti-TSH receptor, anti thyroperoxidase and antithyroglobulin were in normal ranges. Hyperthyroidism may be induced by consumption celery. Although many studies have reported side effects such as allergic reactions for this herb, this is the first report of hyperthyroidism induced by celery in which the patient recovered after discontinuing the medication. Therefore, it can be assumed that celery induces hyperthyroidism as a side effect of this herb if it is used for a long term.

Age-related changes in the antidepressant-like effect of desipramine and fluoxetine in the rat forced-swim test.

Some reports suggest that older patients are less responsive to antidepressants than young adults, but this idea has not been fully supported. Here, we investigated the role of aging in the behavioral effects of the antidepressants, desipramine (DMI) (5, 10, and 20 mg/kg) and fluoxetine (FLX) (5, 10, and 20 mg/kg) in young adults (3-5 months), middle-aged (MA, 12-15 months), and senescent (SE, 23-25 months) male rats in the forced-swim test. In addition, locomotor activity and motor coordination were assessed as side-effects. DMI and fluoxetine produced an antidepressant-like effect in YA and MA animals, although in the latter group, a shift to the right in the dose-response curve was found for DMI. Importantly, neither drug was effective in SE animals. Motor side-effects were produced mainly by DMI in MA and SE rats. Therefore, a decrease in the antidepressant-like effect is associated strongly with senescence as well as an increased vulnerability to motor side-effects, particularly of tricyclics. This study is significant because SE animals are scarcely studied in pharmacological screening tests, and our findings might be useful for improving antidepressant treatments for the increasing aged population.

An experimental wind tunnel test was conducted in the NASA Langley Research Center s 20-Inch Mach 6 Tunnel in support of the Hypersonic International Flight Research Experimentation Program. The information in this report is focused on the Flight 5 configuration, one in a series of flight experiments. This report documents experimental measurements made over a range of Reynolds numbers and angles of attack on several scaled ceramic heat transfer models of the Flight 5 vehicle. The heat transfer rate was measured using global phosphor thermography and the resulting images and heat transfer rate distributions were used to infer the state of the boundary layer on the windside, leeside and side surfaces. Boundary layer trips were used to force the boundary layer turbulent, and a study was conducted to determine the effectiveness of the trips with various heights. The experimental data highlighted in this test report were used determine the allowable roughness height for both the windside and side surfaces of the vehicle as well as provide for future tunnel-to-tunnel comparisons.

To explore and quantify men's preferences and willingness to pay (WTP) for attributes of medications for lower urinary tract symptoms associated with benign prostatic hyperplasia using a discrete choice experiment. Men in the UK aged ≥45 years with moderate-to-severe lower urinary tract symptoms/benign prostatic hyperplasia (based on self-reported International Prostate Symptom Score ≥8) were recruited. An online discrete choice experiment survey was administered. Eligible men were asked to consider different medication scenarios and select their preferred medication according to seven attributes: daytime and nighttime (nocturia) urinary frequency, urinary urgency, sexual and nonsexual side effects, number of tablets/day, and cost/month. A mixed-logit model was used to estimate preferences and WTP for medication attributes. In all, 247 men completed the survey. Men were willing to trade-off symptom improvements and treatment side effects. Men preferred medications that reduced urinary urgency and reduced day- and nighttime urinary frequency. Men preferred medications without side effects (base-case level), but did not care about the number of tablets per day. WTP for symptomatic improvement was £25.33/month for reduced urgency (urge incontinence to mild urgency), and £6.65/month and £1.39/month for each unit reduction in night- and daytime urination frequency, respectively. The sexual and nonsexual side effects reduced WTP by up to £30.07/month. There was significant heterogeneity in preferences for most attributes, except for reduced urinary urgency from urge incontinence to mild urgency and no fluid during ejaculation (dry orgasm). To compensate for side effects, a medicine for lower urinary tract symptoms/benign prostatic hyperplasia must provide a combination of benefits, such as reduced urgency of urination plus reduced nighttime and/or reduced daytime urination.

As methotrexate (MTX) is a widely used treatment for psoriasis, it is important to gain insight into the reasons for the discontinuation of MTX and to understand the determinants for drug survival. To describe 5-year drug survival for MTX in patients with psoriasis, split according to different reasons for discontinuation, and to identify the determinants for drug survival. Data were extracted from a prospective psoriasis registry of patients treated with MTX (MTX-CAPTURE). Drug survival was analysed using Kaplan-Meier estimates and the determinants for discontinuation were analysed using Cox regression analysis. Analyses were split according to the reason for discontinuation: side-effects or ineffectiveness. We included 85 patients treated with MTX, with a maximum treatment duration of 5·2 years. The overall drug survival rates were 63%, 30% and 15% after 1, 3 and 5 years, respectively. The median survival was 1·8 years. Overall, 55 patients (65%) discontinued MTX for the following reasons: side-effects (35%), ineffectiveness (26%), combination of side-effects and ineffectiveness (13%), other reasons (16%) and 11% were lost to follow-up. The most reported side-effects were gastrointestinal symptoms, despite the use of folic acid in 99% of patients. Based on univariate analysis, a high Psoriasis Area and Severity Index score and a high score on the visual analogue scale for disease severity at baseline were possible determinants for a short drug survival. Drug survival of MTX was low with 15% of patients 'on drug' after 5 years. Side-effects alone or in combination with inadequate disease control were more important in the context of treatment discontinuation than inadequate disease control alone. © 2017 British Association of Dermatologists.

The purpose of this work was to evaluate the patient-borne financial cost of common, adverse breast cancer treatment-associated effects, comparing cost across women with or without these side effects. Two hundred eighty-seven Australian women diagnosed with early-stage breast cancer were prospectively followed starting at 6 months post-surgery for 12 months, with three monthly assessments of detailed treatment-related side effects and their direct and indirect patient costs attributable to breast cancer. Bootstrapping statistics were used to analyze cost data, and adjusted logistic regression was used to evaluate the association between costs and adverse events from breast cancer. Costs were inflated and converted from 2002 Australian to 2014 US dollars. More than 90 % of women experienced at least one adverse effect (i.e., post-surgical issue, reaction to radiotherapy, upper-body symptoms or reduced function, lymphedema, fatigue, or weight gain). On average, women paid $5,636 (95 % confidence interval (CI), $4,694, $6,577) in total costs. Women with any one of the following symptoms (fatigue, reduced upper-body function, upper-body symptoms) or women who report ≥4 adverse treatment-related effects, have 1.5 to nearly 4 times the odds of having higher healthcare costs than women who do not report these complaints (p < 0.05). Women face substantial economic burden due to a range of treatment-related health problems, which may persist beyond the treatment period. Improving breast cancer care by incorporating prospective surveillance of treatment-related side effects and strategies for prevention and treatment of concerns (e.g., exercise) has real potential for reducing patient-borne costs.

We proposed a thermoresponsive light scattering device that utilizes the surface behavior between polyimide and an ionic liquid-water mixture exhibiting lower critical solution temperature (LCST)-type phase separation. The LCST behavior for an ionic liquid device utilizing the polyimide with and without alkyl side chains was investigated. In the here-reported ionic liquid device that utilized the polyimide with alkyl side chains, [nBu4P][CF3COO] droplets were generated by phase separation—they were predominantly formed at the alkyl surface by a surface pinning effect. A stable transmittance in the opaque state could be obtained with this device. In contrast, an ionic liquid device using polyimide without alkyl side chains deteriorated transmittance in the opaque state because there was no surface pinning effect. Additionally, the viewing angle, contrast ratio, and heat cycle testing of this ionic liquid device with polyimide with alkyl side chains were also investigated. The results indicated that no parallax was obtained and that the ionic liquid device has a stable transmittance (verified by heat cycle testing). This unique device is expected to find use in the smart window applications that are activated by temperature changes.

Oral appliances (OAs) have been used to treat obstructive sleep apnea (OSA) patients for decades. However, detailed dental side effects in long-term OA cases analyzed with an accurate three-dimensional (3D) measurement tool have seldom been reported. The purpose of this study is to evaluate dental side effects in five OSA patients, who had used a tongue retaining device (TRD) (with occasional other OA wear) for an average of 6 years and 4 months. The baseline and follow-up orthodontic study models were measured with a newly developed MicroScribe-3DX analysis system. High compliance of TRD wear was confirmed in all cases and different patterns and amounts of dental changes were observed. The most common appliance-induced dental changes included anterior and/or unilateral posterior open-bites and reduced anterior overjets. It was hypothesized that there might be two possible mechanisms for the TRD side effects--one is the forward pressure of the tongue upon the anterior dental arch and the other is the lateral pressure of the tongue upon the posterior arch. Considerations to correct the TRD dental side effects should be guided by these different mechanisms of the tongue on the dental arch. Possible solutions to minimize occlusal changes and maximize the benefits for OSA patients are also discussed.

Hyperventilation with and without maintenance of isocapnia: a comparison of selected gasometric and respiratory parameters.

The aims of this study were to examine selected respiratory and gasometric parameters during hyperventilation with and without isocapnia and to identify the possible mechanism by which isocapnic hyperventilation might be useful in the elimination of volatile substances, including CO. Ten healthy non-smoking volunteers were studied, and each underwent two procedures. During one session, CO2 was added to the respiratory circuit, and during the other session, only 100% O2 was used. The volunteers were coached to hyperventilate until the appearance of side effects. Isocapnic hyperventilation significantly increased alveolar minute ventilation and partial pressure of oxygen in arterialized capillary blood (paO2); to the best of our knowledge, these findings have not previously been reported. Isocapnic hyperventilation was associated with only mild side effects, such as dyspnea, increased respiratory effort and headache, in 30% of subjects. Side effects, including vertigo, paresthesias and muscle tremor, were present in 70% of the volunteers during hyperventilation with 100% O2, and these side effects forced them to limit their respiratory rates and tidal volumes. These increases in alveolar ventilation and the partial pressure of oxygen in the blood may play crucial roles in decreasing the half-time of carboxyhemoglobin, which is the primary goal of the treatment of CO poisoning.

Stimulant Use in Patients with Sturge-Weber Syndrome: Safety and Efficacy

PubMed Central

Lance, Eboni I.; Lanier, Kira E.; Zabel, T. Andrew; Comi, Anne M.

2015-01-01

BACKGROUND Sturge Weber Syndrome (SWS) is characterized by a facial port-wine birthmark, vascular eye abnormalities, and a leptomeningeal angioma. Attention and behavioral issues are common in SWS; however, literature evidence for stimulant treatment is minimal. This study evaluates stimulant medication safety and efficacy in SWS patients. METHODS The research database of the Hunter Nelson Sturge-Weber Center (n = 210 subjects with SWS brain involvement) was reviewed for stimulant use. Twelve subjects (mean age 10.5 years, age range 4 to 21 years) on stimulants were seen between 2003 and 2012. A retrospective chart review obtained co-morbid diagnoses, stimulant type and dosage, medication side effects, vital signs, and medication efficacy. RESULTS All twelve subjects had brain involvement (unilateral - nine; bilateral – three). Additional co-morbidities included epilepsy (twelve), hemi-paresis (eight), headaches (eight), and vision deficits (seven). Eight subjects reported side effects, primarily appetite suppression (four) and headaches (three). There were no statistically significant changes in weight or blood pressure six months after medication initiation. Medication efficacy was subjectively reported in eleven subjects. Seven patients remained on stimulants at their most recent follow up visit. CONCLUSIONS This study preliminarily evaluates stimulant medication use in a small group of SWS patients. Stimulants were tolerated and effective in most subjects. Side effects were mostly minor and medication did not negatively impact growth or vital signs. Stimulant medication may be a safe and effective intervention for SWS children with attention issues/attention deficit hyperactivity disorder (ADHD). Further studies with larger sample sizes are needed. PMID:25439578

Background. The South African (SA) government introduced Implanon NXT, a long-acting subdermal contraceptive implant, in 2014 to expand contraceptive choice. Following an initial high uptake, its use declined considerably amid reports of early removals and frequent side-effects. We examine providers’ perceptions of training and attitudes towards Implanon NXT, as well as their views on the causes of early removals and the impact on the implant service. Objective. To assess healthcare providers’ perceptions and attitudes towards implant services in SA. Methods. In-depth interviews were conducted with eight nurses providing implant services in public facilities in Gauteng and North West Province. Emerging themes were identified, manually coded and thematically analysed following an interpretivism approach. Results. Nurses lacked confidence in providing implant services effectively, particularly removals, which they ascribed to the brief, cascade-type training received. Nurses generally held negative views towards the method. They also reported that side-effects are the most common reason for early removals – particularly irregular bleeding – and that men often do not support their partners who use the method. Lastly, it was found that providers require guidance on counselling regarding the method and standardised guidelines on the management of side-effects. Conclusion. Retraining and support of providers are needed to address competency gaps and negative attitudes towards the method. Assessment of providers’ readiness to perform removal procedures is also important. Finally, effective plans are necessary to improve implant continuation rates, especially among women whose partners are unsupportive.

Bosco, Domenico; Plastino, Massimiliano; Marcello, Maria Giovanna; Mungari, Pasquale; Fava, Antonietta

2009-01-01

Dystonic reactions produce twisting and repetitive movements or abnormal posturing. Severe dystonic reactions have been shown to occur in concert with numerous medications. This report details the case of a patient who developed hemifacial dystonia as acute side reaction from administration of clebopride for dyspeptic prophylaxis. When the drug was immediately stopped, the dystonic posture disappeared completely within 2 weeks. The use of clebopride may be associated with not only a reversible or persistent parkinsonism syndrome but also hemifacial dystonia; therefore, attention must be drawn to this possible side effect.

Antiepileptic drug therapy: clinical laboratory significance.

Naradzay, J F; Olshaker, J S

1996-01-01

When evaluating a patient who is taking an antiepileptic medication, it is important for the emergency physician to correlate the clinical presentation with the antiepileptic drug level. Therapeutic ranges have been suggested for most antiepileptic medications, but these must be interpreted in light of clinical efficacy and patient tolerance. When considering the efficacy of anti-epileptic medications, it is necessary to consider the patient's unique metabolism, side-effect tolerance, and overall response to therapy. Suggested therapeutic ranges should be the first reference for the emergency physician. The purpose of this report is to discuss the laboratory values of commonly prescribed antiepileptic medications. Therapeutic ranges, side-effects, and common medication interactions are discussed concerning phenytoin, phenobarbital, carbamezapine, and valproic acid.

Interferon beta-1a is available as an immunomodulating agent for relapsing forms of multiple sclerosis. Common side effects include flu-like symptoms, asthenia, anorexia, and administration site reaction. Kidney disorders are rarely reported. In this study we describe the case of a woman who has been undergoing treatment with interferon beta-1a for multiple sclerosis for 5 years. She developed a hemolytic-uremic syndrome with intravascular hemolysis in a context of severe hypertension. A kidney biopsy showed a thrombotic microangiopathy. This observation highlights an uncommon side effect of long-term interferon beta-1a therapy. Pathophysiological mechanisms leading to this complication might be explained by the antiangiogenic activity of interferon. PMID:23950639

A Case Report: Subanesthetic Ketamine Infusion for Treatment of Cancer-Related Pain Produces Urinary Urge Incontinence.

2017-05-01

Oncology patients undergoing treatment can experience substantial pain related to their disease or prescribed therapy. Ketamine infusions at subanesthetic doses have been used at our institution to supplement the pain management regimens of 262 patients. We present 2 cases in which young adult patients being treated with subanesthetic ketamine for cancer-related pain experienced urinary urgency and incontinence after initiation or increase of the ketamine infusion. This adverse effect has not been reported previously at this dosing range. These case reports suggest that subanesthetic ketamine infusions may cause side effects that previously have been reported only at anesthetic or abuse doses.

Memory for Medication Side Effects in Younger and Older Adults: The Role of Subjective and Objective Importance

Friedman, Michael C.; McGillivray, Shannon; Murayama, Kou; Castel, Alan D.

2014-01-01

Older adults often experience memory impairments, but can sometimes use selective processing and schematic support to remember important information. The current experiments investigate to what degree younger and healthy older adults remember medication side effects that were subjectively or objectively important to remember. Participants studied a list of common side effects, and rated how negative these effects were if they were to experience them, and were then given a free recall test. In Experiment 1, the severity of the side effects ranged from mild (e.g., itching) to severe (e.g., stroke), and in Experiment 2, certain side effects were indicated as critical to remember (i.e., “contact your doctor if you experience this”). There were no age differences in terms of free recall of the side effects, and older adults remembered more severe side effects relative to mild effects. However, older adults were less likely to recognize critical side effects on a later recognition test, relative to younger adults. The findings suggest that older adults can selectively remember medication side effects, but have difficulty identifying familiar but potentially critical side effects, and this has implications for monitoring medication use in older age.

Objective To review published literature regarding the pharmacology and use of amantadine in child and adolescent psychiatry. Method A literature search of several databases (PubMed, Psychinfo, CINAHL, Medline, PsycARTICLES, Biomedical Reference Collection and Academis Search Complete) was conducted with the search terms: ‘amantadine’ with limits: English language, Human trials, all child (aged 0–18 years). The search was later expanded to include ‘Adults’ and additional relevant articles were selected from reference lists. Results The psychotropic effect of amantadine is related to its antagonism of the N-methyl-D-aspartate (NMDA) receptor. It decreases the toxic effects of the glutamatergic neurotransmitter system which plays an important role in many psychiatric disorders. Two randomized controlled trials (RCTs) of amantadine were identified in children and adolescents. One reported beneficial effects in controlling the symptoms of irritability and hyperactivity in autistic disorder and the other described a significant impact in attention deficit hyperactivity disorder (ADHD). Two open label studies also reported positive effects in ADHD. A pilot study in children with enuresis reported significant reduction in wetting frequency. Studies in adults, with relevance to children and adolescents, reported effectiveness in resistant depression, obsessive compulsive disorder and in counteracting side effects of some psychotropic medications. RCTs found in traumatic brain injury indicated a neuroprotective effect and effectiveness in controlling agitation and aggression. Amantadine is well tolerated in children and adolescents, with an acceptable side effect profile, and considered safe for long term use. Conclusion Amantadine shows potential for use as a safe alternative or as an augmenting agent for treating children with neuropsychiatric and various other disorders. Available data for such use, although promising, require further confirmation. PMID:23390434

Objective: To evaluate the consumption, prevalence, side effects and awareness of energy drinks among female university students in Saudi Arabia. Methods: A quantitative research design was implied with sample size of 358 female students, recruited from Prince Sattam bin Abdulaziz University. The data, gathered through self-administered questionnaire, was analyzed through SPSS version 20.0 with p value <0.005 deemed statistically significant. Results: From the sample of 358 female students, 337 attempted the questionnaire from which 274 students were identified as energy drink consumers. The reasons for increased consumption of energy drinks mainly include giving company to friends (59.4%), better performance in exams (41.2%), and better concentration in studies (39.4%). The most common side effect was headache (32.3%), and the least was identified as allergy (2%). Only 39.4% and 29.9% of students acquired awareness regarding the harmful effects of energy drink consumption during pregnancy and breast feeding respectively. Conclusion: A significant proportion of female students at Prince Sattam bin Abdulaziz have reported to consume energy drinks regularly with several adverse effects. The government of Saudi Arabia should take serious initiatives towards organizing effective awareness programs specifically in universities and colleges to control the consumption of energy drinks and educate on the adverse effects.

This pilot study examined the effects of Reiki therapy and companionship on improvements in quality of life, mood, and symptom distress during chemotherapy. Thirty-six breast cancer patients received usual care, Reiki, or a companion during chemotherapy. First, data were collected from patients receiving usual care. Second, patients were randomized to either receive Reiki or a companion during chemotherapy. Questionnaires assessing quality of life, mood, symptom distress, and Reiki acceptability were completed at baseline and chemotherapy sessions 1, 2, and 4. Reiki was rated relaxing with no side effects. Reiki and companion groups reported improvements in quality of life and mood that were greater than those seen in the usual care group. Interventions during chemotherapy, such as Reiki or companionship, are feasible, acceptable, and may reduce side effects. © The Author(s) 2014.

1992-01-01

The Space Plasma-High Voltage Drainage Experiment (SP-HVDE) provided a unique opportunity to study long term space environmental effects on materials because it was comprised of two identical experimental trays; one tray located on the ram facing side (D-10), and the other on the wake facing side (B-4) of the LDEF. This configuration allows for the comparison of identical materials exposed to two distinctly different environments. The purpose of this work is to document an assessment of the effects of five and three quarters years of low Earth orbital space exposure on materials comprising the SP-HVDE (experiment no. A0054). The findings of the materials investigation reported focus on atomic oxygen effects, micrometeor and debris impact site documentation, thermal property measurements, and environmentally induced contamination.

“So far it’s been choosing which side effects I want or I can deal with”: A grounded theory of HIV treatment side effects among people living with HIV

Holmes, Dave

2016-01-01

Despite the availability of new antiretroviral drugs and the simplification of treatment options, side effects continue to affect people living with HIV. In this paper, we present the findings of a grounded theory study designed to gain a critical understanding of the experience of side effects. Three main categories emerged from the data: the side effects, the experience, and the connections. The first category suggests that we need to change how we think about side effects in order to take into account the context in which they are experienced as well as the types and nature of side effects. The second category puts forward the idea that the experience of side effects is composed of three interrelated processes: becoming with, living with, and dealing with. Finally, the third category points to new connections that are formed with people, things and systems in the presence of side effects. PMID:27867446

This review summarizes the pharmacokinetic characteristics, pharmacodynamic properties, common side effects, and clinical advantages and disadvantages associated with atomoxetine (ATX) treatment in typically developing children and adults with ADHD. Then the clinical research to date in developmental disabilities (DD), including autism spectrum disorders (ASD), is summarized and reviewed. Of the 11 relevant reports available, only two were placebo-controlled randomized clinical trials, and both focused on a single DD population (ASD). All trials but one indicated clinical improvement in ADHD symptoms with ATX, although it was difficult to judge the magnitude and validity of reported improvement in the absence of placebo controls. Effects of ATX on co-occurring behavioral and cognitive symptoms were much less consistent. Appetite decrease, nausea, and irritability were the most common adverse events reported among children with DD; clinicians should be aware that, as with stimulants, irritability appears to occur much more commonly in persons with DD than in typically developing individuals. Splitting the dose initially, starting below the recommended starting dose, and titrating slowly may prevent or ameliorate side effects. Patience is needed for the slow build-up of benefit. Conclusions: ATX holds promise for managing ADHD symptoms in DD, but properly controlled, randomized clinical trials of atomoxetine in intellectual disability and ASD are sorely needed. Clinicians and researchers should be vigilant for emergence of irritability with ATX treatment. Effects of ATX on cognition in DD are virtually unstudied. PMID:24732041

Androgenic-anabolic steroids (AAS) are abused by a growing number of bodybuilders. This descriptive cross-sectional study was conducted to determine prevalence and patterns of AAS use by bodybuilders in Hamadan, western Iran. In this cross-sectional study, participants were recruited from five gym clubs in two area of Hamadan (a total of 10 clubs). Twenty-five bodybuilders from each club were administered. Questions investigating demographic information, sport history, education level, general knowledge about AAS, and their side effects were asked. Statistical analysis was performed using SPSS 16. The frequency of AAS use was 28.8% (72/250). Fifty-four percent of users were 25 years or younger. AAS abuse showed a significant association with duration of exercise. The drugs were suggested mostly from peers (43.1%) and coaches (36.1%). The most commonly consumed anabolic steroid was testosterone (66.7%). The most commonly reported AAS side effect was acne (18.1%). There was not significant association between general knowledge about side effects of ASS and their use. The results of current survey indicate that frequency of ASS use is high in adolescents and young adult bodybuilders. Well educated bodybuilders have a higher prevalence of abuse. Awareness about the side effects of drugs is not deterrent factor for their abuse. Iranian Ministry of Sport and the Youth, and the National Council for Youth, should be urged to conduct more effective prevention strategies.

The desired (therapeutic) and undesired (side) effects of methylphenidate might have underlying correlations. The aim of this study was to explore the strength and the possible sources of these correlations. One hundred and fifty-seven children with ADHD (6-12 years) were administered placebo and methylphenidate (0.5 mg/kg in a divided b.i.d. dose), each for a one-week period, in a double-blind, crossover trial. Therapeutic response was assessed using the Conners' Global Index for parents (CGI-Parents) and teachers (CGI-Teachers), while side effects were assessed using the Barkley Side Effects Rating Scale (SERS). The side effect profile as assessed by the SERS was similar to that of previous studies with insomnia, decreased appetite, and headaches showing significant treatment effects (p < 0.005). These "somatic/physical" side effects did not correlate with CGI-Parents or CGI-Teachers. However, the side effects of "irritability", "proneness to crying", and "anxiousness" showed significant relationships with CGI-Parents. These "mood/anxiety" side effects showed no significant correlations with the CGI-Teachers. The greater "mood/anxiety" side effects on methylphenidate and placebo, the less the parents observe improvement of their children while treated with methylphenidate. This suggests that the correlations between "mood/anxiety" side effects and poor response to treatment may be driven by observer effects rather than biological commonalities between therapeutic and side effects of methylphenidate.

A subsonic wind tunnel investigation of pneumatic vortex flow control on a chined forebody using slots was accomplished at a dynamic pressure of 50 psf resulting in a R(n)/ft of 1.3 x 10(exp 6). Data were acquired from angles of attack ranging from -4deg to +34deg at side slips of +0.4deg and +10.4deg. The test article used in this study was the 10% scale Fighter Lift and Control (FLAC) advanced diamond winged, vee-tailed fighter configuration. Three different slot blowing concepts were evaluated; outward, downward, and tangential with ail blowing accomplished asymmetrically. The results of three different mass flows (0.067, 0.13, and 0.26 lbm/s; C(sub mu)'s of less than or equal to 0.006, 0.011. and 0.022 respectively) were analyzed and reported. Test data are presented on the effects of mass flows, slot lengths and positions and blowing concepts on yawing moment and side force generation. Results from this study indicate that the outward and downward blowing slots developed yawing moment and side force increments in the direction opposite of the blowing side while the tangential blowing slots generated yawing moment and side force increments in the direction towards the blowing side. The outward and downward blowing slots typically produced positive pitching moment increments while the tangential blowing slots typically generated negative pitching moment increments. The slot blowing nearest the forebody apex was most effective at generating the largest increments and as the slot was moved aft or increased in length, its effectiveness at generating forces and moments diminished.

The comparative efficacy of molindone and haloperidol, given by injection for the first 2-3 days of hospitalization and then continued orally for up to 4 weeks, is reported from an ongoing double-blind study. Efficacy and side effects were assessed by the Brief Psychiatric Rating Scale, Clinical Global Impressions, Treatment Emergent Symptom Scale, and Target Symptom Ratings. Analyses based on the first 35 patients who entered the study indicate that both drugs were effective and well tolerated. There were slight advantages for molindone early during the injectable phase of treatment and for haloperidol late during the oral portion of the study, but these differences were not clinically significant. No significant differences in side effects were found between the two drugs.

Relapse after discontinuation of ECT is significant in patients with schizophrenia. The purpose of this systematic review was to examine use of M-ECT in schizophrenia to guide clinical decision making for relapse prevention in schizophrenia. We reviewed studies examining the role of continuation (C-ECT) and maintenance electroconvulsive therapy (M-ECT) in schizophrenia. Following PRISMA guidelines, we included randomized controlled trials, open label trials, retrospective chart reviews, case reports, and case series in this review. We evaluated adjunctive pharmacological regimens; ECT treatment parameters, including frequency, duration of continued treatment, electrode placement; clinical outcomes including cognitive side effects and relapse rates from included studies. Our findings suggest M-ECT could provide an effective form of relapse prevention in these patients and persistent cognitive side effects are minimal. Copyright © 2018 Elsevier B.V.

Gastrointestinal toxicity is one of the most serious side effects of methotrexate (MTX) treatment. The side effects often disrupt the cancer chemotherapy. We previously reported that aged garlic extract (AGE) protects the small intestine of rats from MTX-induced damage. In this study, the protection of AGE against MTX-induced damage of IEC-6 cells originating from the rat jejunum crypt was investigated. MTX decreased the viability of IEC-6 cells, but this effect was prevented by AGE (0.5%). The MTX-induced apoptosis of IEC-6 cells was depressed by AGE. These results indicated that AGE protects IEC-6 cells from the MTX-induced damage. AGE may be useful in cancer chemotherapy with MTX because it reduces MTX-induced intestinal damage.

Martensitic transition is a solid-state phase transition involving cooperative movement of atoms, mostly studied in metallurgy. The main characteristics are low transition barrier, ultrafast kinetics, and structural reversibility. They are rarely observed in molecular crystals, and hence the origin and mechanism are largely unexplored. Here we report the discovery of martensitic transition in single crystals of two different organic semiconductors. In situ microscopy, single-crystal X-ray diffraction, Raman and nuclear magnetic resonance spectroscopy, and molecular simulations combined indicate that the rotating bulky side chains trigger cooperative transition. Cooperativity enables shape memory effect in single crystals and function memory effect in thin film transistors. We establish a molecular design rule to trigger martensitic transition in organic semiconductors, showing promise for designing next-generation smart multifunctional materials.

High yield of secondary B-side electron transfer in mutant Rhodobacter capsulatus reaction centers

DOE Office of Scientific and Technical Information (OSTI.GOV)

Kressel, Lucas; Faries, Kaitlyn M.; Wander, Marc J.

2014-08-01

From the crystal structures of reaction centers (RCs) from purple photosynthetic bacteria, two pathways for electron transfer (ET) are apparent but only one pathway (the A side) operates in the native protein-cofactor complex. Partial activation of the B-side pathway has unveiled the true inefficiencies of ET processes on that side in comparison to analogous reactions on the A side. Of significance are the relative rate constants for forward ET and the competing charge recombination reactions. On the B side, these rate constants are nearly equal for the secondary charge-separation step (ET from bacteriopheophytin to quinone), relegating the yield of thismore » process to < 50%. Herein we report efforts to optimize this step. In surveying all possible residues at position 131 in the M subunit, we discovered that when glutamic acid replaces the native valine the efficiency of the secondary ET is nearly two-fold higher than in the wild-type RC. The positive effect of M131 Glu is likely due to formation of a hydrogen bond with the ring V keto group of the B-side bacteriopheophytin leading to stabilization of the charge-separated state involving this cofactor. In conclusion, this change slows charge recombination by roughly a factor of two and affords the improved yield of the desired forward ET to the B-side quinone terminal acceptor.« less

Innate Immune Response and Off-Target Mis-splicing Are Common Morpholino-Induced Side Effects in Xenopus.

PubMed

Gentsch, George E; Spruce, Thomas; Monteiro, Rita S; Owens, Nick D L; Martin, Stephen R; Smith, James C

2018-03-12

Antisense morpholino oligomers (MOs) have been indispensable tools for developmental biologists to transiently knock down (KD) genes rather than to knock them out (KO). Here we report on the implications of genetic KO versus MO-mediated KD of the mesoderm-specifying Brachyury paralogs in the frog Xenopus tropicalis. While both KO and KD embryos fail to activate the same core gene regulatory network, resulting in virtually identical morphological defects, embryos injected with control or target MOs also show a systemic GC content-dependent immune response and many off-target splicing defects. Optimization of MO dosage and increasing incubation temperatures can mitigate, but not eliminate, these MO side effects, which are consistent with the high affinity measured between MO and off-target sequence in vitro. We conclude that while MOs can be useful to profile loss-of-function phenotypes at a molecular level, careful attention must be paid to their immunogenic and off-target side effects.

The prevalence of asthma in our society is rising and there is need for better understanding of the asthma patients' perception and treatment practice of physicians. The study was aimed at determining asthma attitudes and treatment practices among adult physicians and patients in Nigeria, with the goal of identifying barriers to optimal management. To assess asthma attitudes, treatment practices and limitations among adult physicians and patients in Nigeria, a questionnaire survey was conducted among 150 patients and 70 physicians. Majority (66.7%) of the patients reported their asthma as moderate to severe, 42.7% had emergency room visit and 32% had admission due to asthma in the previous 12 months. Physicians and patients perceptions significantly differed in the time devoted to educational issues (31.4% vs.18.7%) and its contents: individual management plan (64.3% vs.33.3%), correct inhaler technique (84.0% vs.71.0%), medication side effects (80.0% vs.60.0%) and compliance 100% of time (5.7% vs. 18.7%). Patients reported that non-compliance with medication causes increased symptoms (67.0%), exacerbations (60.0%), bronchodilator use (56.0%), urgent physician visit (52.0%) and hospitalizations /ER visits (38.7%). Asthma medication in patients caused short term (10.7%) and long term side effects (20.0%). Due to side effects, 28.0% skipped and stopped their medications. Most physicians (85.7%) and patients (56.0%) agreed on the need for new medication options. The need for new medication in patients was strongly related to asthma severity, limitation of activities, side effects, cost and lack of satisfaction with current medication. With the exception of pulmonologists, physicians did not readily prescribe ICS and their prescriptions were not in line with treatment guidelines. This study has highlighted the gaps and barriers to asthma treatment which need to be addressed to improve the quality of care in Nigeria.

  The long-term patient satisfaction and safety of nightguard vital bleaching (NGVB) requires further evaluation.   The purpose of this study was to evaluate patients' satisfaction and identify side effects of NGVB up to 17 years post-treatment.   Thirty-one participants who had completed previous NGVB studies using 10% carbamide peroxide were contacted at least 10 years post-treatment (range 10-17 years, average 12.3 years). Participants reported shade satisfaction (very satisfied [VS], partially satisfied [PS], or not satisfied [NS]) as well as potential complications. Participants had teeth # 6 to 11 examined for tooth vitality, gingival inflammation (Löe's Gingival Index [GI]), and radiographically for external cervical resorption (ECR).   All of the participants had successful lightening of their teeth. Sixty-one percent (19) had not retreated their teeth. Of those who had not retreated their teeth and who responded to the question of whitening satisfaction, 31% (4/13) were VS, 54% (7/13) were PS, and 15% (2/13) were NS with their current shade. Of those who had retreated their teeth, all were VS or PS. Ninety-one percent of the examined teeth had GI = 0 (normal), 7% had GI = 1 (mild inflammation), and 2% had GI = 2 (moderate inflammation). Sixty-nine percent of teeth tested responded to a cold stimulus. Radiographs did not detect ECR or apical lesions. No participant reported having a gingival biopsy post-treatment, and 87% would whiten again.   Patient satisfaction with NGVB may last as long as 12.3 years in average (range 10-17 years) post-treatment. GI and ECR findings were considered within the normal expectations for the sample studied, suggesting minimal clinical post-NGVB side effects up to 17 years. Nightguard vital bleaching provides patient satisfaction with minimal side effects up to 17 years post-treatment. © 2011 Wiley Periodicals, Inc.

The prevalence of dietary-related complementary and alternative therapies and their perceived usefulness among cancer patients.

2009-12-01

The present study aimed to directly assess and compare the usage, benefits and side-effects of dietary-related complementary and alternative medicine (CAM) use among adult cancer patients and non-cancer adults in Norwich, UK. Self-administered questionnaires were completed by 98 cancer patients and 92 non-cancer adults to compare demographics, types of CAM usage with reasons, benefits, side-effects and CAM information sources. The groups were matched for gender, age, marital status, education and household income. The mean ages were 62.7 and 59.7 years, respectively, with slightly more female than male participants. CAM use was high in both groups (47% in cancer and 53% in non-cancer respondents, P > 0.05). The most widely-used diet-related CAM among both groups was the large intake of fruit, vegetables and juice, multivitamins, fish oils and glucosamine. Fish oil intake was significantly higher in the non-cancer group (P < 0.05), whereas selenium and beta-carotene supplements were significantly higher in the cancer group (P < 0.01 and P = 0.02, respectively). The main reasons for using CAM were to boost the immune system and to improve quality of life (P > 0.05). Reported benefits included increased optimism and hope for the cancer group and increased optimism and pain relief for the non-cancer group. Diet-related CAM is used frequently by both cancer patients and non-cancer adults, with many reported benefits and few reported side-effects. Significant differences between the groups included a higher prevalence of fish oil used by the non-cancer group, and a higher use of selenium and beta-carotene supplements in the cancer group.

2015-01-01

The aims of this study were (1) to compare health outcomes (i.e., health-related quality of life [HRQoL], productivity at work, and healthcare resource use visits) between those with insomnia and non-insomnia controls, (2) to compare health outcomes between those treated for insomnia and non-insomnia controls, and (3) to assess the prevalence of side effects of insomnia medications and their relationship with health outcomes. Data from the 2013 US (N = 75,000) and 5EU (N = 62,000) National Health and Wellness Survey (NHWS) were used. The NHWS is a patient-reported survey administered to a demographically representative sample of adults. Those who met DSM-V criteria for insomnia and, separately, those treated for insomnia were compared with equivalently sized control groups who were identified using a propensity score matching method. Outcomes included HRQoL (Short Form 36v2), productivity at work (Work Productivity and Activity Impairment—General Health questionnaire), and healthcare resource use visits in the past 6 months and were analyzed using one-way ANOVAs. Among those with treated insomnia, those with and without side effects were compared on health outcomes using general linear models controlling for confounding variables. Patients with insomnia (n = 4147) and treated insomnia (n = 2860) in the 5EU reported significantly worse HRQoL than controls (health utilities: 0.60 vs. 0.74; 0.60 vs. 0.74, respectively), greater overall work impairment (38.74% vs. 14.86%; 39.50% vs. 15.66%), and more physician visits in the past 6 months (9.10 vs. 4.08; 9.58 vs. 4.11). Similar findings were observed in the US. Among those treated for insomnia, 13.56% and 24.55% in the US and 5EU, respectively, were non-adherent due to side effects. In the US, non-adherence was associated with significantly worse HRQoL (health utilities: 0.60 vs. 0.64, p <.05) and greater overall work impairment (37.71% vs. 29.08%, p <.05), among other significant differences. These relationships were not significant in the 5EU. A significant burden of insomnia was observed in both the US and 5EU, and the association remained even after treatment. Non-adherence due to side effects was common and, in the case of the US, associated with significantly poorer health outcomes. PMID:26426805

Leukotriene receptor antagonists (LTRAs) are drugs which have been widely used more than ten years. As the use of LTRAs increases, our knowledge with respect to their side effects increases as well. The objective of our study was to evaluat the observed side effects of LTRAs used in patients with astma. 1024 patients treated only with LTRAs owing to asthma or early wheezing were included in the study for a five-year period. The observed side effects of LTRAs in these patients were retrospectively investigated. The side effects were divided into two parts as psychiatric and non-psychiatric. Among the 1024 cases included in the study, 67.5% of the patients out of 41 with side effects were male, 32.5% were female and the average age was 6.5 years. The rate of patients with asthma was 63.41% and 36.58% of the patients had early wheezing. It was determined that sex, age and diagnosis (early wheezing or asthma) of the patients were ineffective in the emergence of side effects. The average period for the emergence of side effects was the first month. It was observed that hyperactivity was the most frequently observed psychiatric side effect and that abdominal pain was the non-psychiatric side effect. The side effects of LTRAs were common in children. Therefore, patients must be informed at the beginning of the treatment and they must be evaluated at certain intervals.

Experiences and coping strategies of oncology patients undergoing oral chemotherapy: First steps of a grounded theory study.

Chemotherapies are increasingly available for oral application. Previous studies have focussed on differences between orally and intravenously administered chemotherapies, mostly following quantitative designs surveying patients' preferences and adherence. The lived experience of patients undergoing oral chemotherapy has been rarely explored. Therefore, this study investigates how patients experience oral chemotherapy. We conducted open interviews with six patients and two spouses. Recruitment took place in the outpatient clinic of an urban Swiss hospital. Data collection and analysis followed the principles of Straussian grounded theory. The participants reported physical and emotional reluctance towards oral chemotherapy as well as toxic side effects. Feeling responsible emerged as a core phenomenon. All participants intended to adhere to the therapy although this was challenging because of the complex medication regimen. Belief in the effectiveness of the therapy was a strengthening factor. All participants reported to be highly adherent to oral chemotherapy. Although they experienced some toxic side effects, they did not react. Monitoring toxicities and support in everyday life should be a core feature of care. Copyright © 2016 Elsevier Ltd. All rights reserved.

Apatinib is a novel tyrosine kinase inhibitor targeting vascular endothelial growth factor receptor-2, which has been proved to be effective and safe in treating heavily pretreated patients with gastric cancer.The aim of the study was to explore the use of apatinib in treatment of nonsmall cell lung cancer and its side effects.We report 2 patients presented with advanced nonsmall-cell lung cancer, who received apatinib after failure in the first- or third-line chemotherapy. They are treated with apatinib in daily dose of 850 mg, 28 days per cycle.Favorable oncologic outcomes were achieved in the 2 cases after the treatment of apatinib. Patient I's progression-free-survival has increased to 4.6 months after palliative therapy of apatinib, whereas Patient II nearly 6 months. The common side effects of apatinib were hypertension and hand-foot syndrome; however, the toxicity of apatinib was controllable and tolerable.Apatinib may be an option for advanced nonsmall cell lung cancer after failure of chemotherapy or other targeted therapy. But that still warrants further investigation in the prospective study.

Fenofibrate monotherapy-induced rhabdomyolysis in a patient with hypothyroidism: A rare case report and literature review.

2018-04-01

Fenofibrate is a fibric acid derivative indicated for use in hypertriglyceridemia and mixed dyslipidemia treatment among adults. Rhabdomyolysis is a syndrome characterized by muscle necrosis and the release of intracellular muscle contents into the systemic circulation, which is the most serious and fatal side effect of fenofibrate. The objective of this paper is to discuss fatal side effect of fenofibrate and keep safe medication. A patient with hypothyroidism who presented with rhabdomyolysis during fenofibrate monotherapy for hypertriglyceridemia was reported. Fenofibrate Monotherapy Induced Rhabdomyolysis. Fenofibrate was stopped. Adequate fluid resuscitation, mannitol diuresis, myocardium protection, hepatoprotection and urine alkalinization with sodium bicarbonate were performed. Blood tests were normal and the patient was good and discharged 2 weeks later. 13 cases associated with fenofibrate monotherapy-induced rhabdomyolysis were reviewed, which had been published in the English literature. The severity of fenofibrate muscle toxicity may be the result of the combination of two rhabdomyolysis enhancers, such as hypothyroidism and female gender. To avoid it, strict clinical and laboratory monitoring should be maintained, particularly hypothyroidism. Patients should be informed of possible potentially irreversible effects after taking fibrates.

Drug safety evaluation of dronedarone in atrial fibrillation.

PubMed

De Ferrari, Gaetano M; Dusi, Veronica

2012-11-01

Dronedarone was developed with the intent of replicating the antiarrhythmic effects of amiodarone, while minimizing its side effects. Side effects reported in eight randomized clinical trials are discussed, comparing dronedarone and placebo (DAFNE, EURIDIS, ADONIS, ERATO, ANDROMEDA, ATHENA, PALLAS, total number of patients treated with dronedarone 5347), or dronedarone and amiodarone (DIONYSOS, total number of patients treated with dronedarone 249). The results of the first trials, including ATHENA, set high expectations by suggesting that dronedarone may decrease the risk of hospitalization (and even cardiovascular mortality) among patients with paroxysmal and persistent atrial fibrillation (AF), and that it could be regarded as an easy-to-use drug that could be prescribed by general practitioners; unfortunately, dronedarone has not met these expectations. Dronedarone may increase mortality and heart failure hospitalization in patients with advanced NYHA class and in patients with permanent AF, preventing its use in these settings. In addition to gastrointestinal side effects that may lead to discontinuation in 5 - 10% of patients, dronedarone may induce very rare but severe liver and lung toxicity. Despite these limitations and its relatively limited antiarrhythmic potency, dronedarone may still be a useful drug for well-selected patients.

Neuroversion: using electroconvulsive therapy as a bridge to deep brain stimulation implantation.

2017-02-01

Parkinson's disease (PD) is a movement disorder with significant neuropsychiatric comorbidities. Electroconvulsive therapy (ECT) is effective in treating these neuropsychiatric symptoms; however, clinicians are reluctant to use ECT in patients with deep brain stimulation (DBS) implantations for fear of damaging the device, as well as potential cognitive side effects. Right unilateral ultra-brief pulse (RUL UBP) ECT has a more favorable cognitive side-effect profile yet has never been reported in PD patients with DBS implants. We present a case series of three patients with a history of PD that all presented with psychiatric decompensation immediately prior to planned DBS surgery. All three patients had DBS electrode(s) in place at the time and an acute course of ECT was utilized in a novel method to "bridge" these individuals to neurosurgery. The patients all experienced symptom resolution (psychosis and/or depression and/or anxiety) without apparent cognitive side effects. This case series not only illustrates that right unilateral ultra-brief pulse can be utilized in patients with DBS electrodes but also illustrates that this intervention can be utilized as a neuromodulatory "bridge", where nonoperative surgical candidates with unstable psychiatric symptoms can be converted to operative candidates in a manner similar to electrical cardioversion.

Comparing the effects of repetitive transcranial magnetic stimulation and electroconvulsive therapy in the treatment of depression: a systematic review and meta-analysis.

PubMed

Micallef-Trigona, Beppe

2014-01-01

Electroconvulsive therapy (ECT) is the longest standing psychiatric treatment available and has unequivocal benefit in severe depression. However this treatment comes with a number of side effects such as memory impairment. On the other hand, Repetitive Transcranial Magnetic Stimulation (rTMS) is a relatively new form of treatment which has been shown to be efficacious in patients suffering from a number of psychopathologies, including severe depression, with few reported side effects. Due to its potential therapeutic efficacy and lack of side effects, rTMS has gained traction in the treatment of depression, with a number of authors keen to see it take over from ECT. However, it is not clear whether rTMS represents a therapeutic alternative to ECT. This meta-analysis will therefore compare the "gold standard" treatment for severe depression, with the relatively new but promising rTMS. A literature search will be performed with the intention to include all randomised clinical trials. The null hypothesis is that there is no difference in the antidepressant efficacy between the two types of treatment modalities. Statistical analysis of Hamilton Depression Rating Scale (HDRS) scores will be performed.

Asymmetry-symmetry transition of double-sided adhesive tapes

NASA Astrophysics Data System (ADS)

Yamaguchi, Tetsuo; Muroo, Hiroyuki; Sumino, Yutaka; Doi, Masao

2012-06-01

We report on the debonding process of a double-sided adhesive tape sandwiched between two glass plates. When the glass plates are separated from each other at a constant rate, a highly asymmetric extension of top and bottom adhesive layers and bending of the inner film are observed first. As the separation proceeds, the elongation of both layers becomes symmetric, and the inner film becomes flat again. When this happens, there appears a local maximum in the force-displacement curve. We explain this asymmetry-symmetry transition and discuss the role of the bimodal force-displacement relation of each adhesive layer. We also discuss the effect of the inner film thickness and the separation rate on the debonding behavior, which causes undesirable early detachment of the double-sided adhesive tape in a certain condition.

Tamoxifen and aromatase inhibitors are associated with side effects which can significantly impact quality of life (QoL). We assessed QoL in the Tamoxifen Exemestane Adjuvant Multinational (TEAM) Trial and compared these data with reported adverse events in the main database. 2,754 Dutch postmenopausal early breast cancer patients were randomized between 5 years of exemestane, or tamoxifen (2.5-3 years) followed by exemestane (2.5-2 years). 742 patients were invited to participate in the QoL side study and complete questionnaires at 1 (T1) and 2 (T2) years after start of endocrine treatment. Questionnaires comprised the EORTC QLQ-C30 and BR23 questionnaires, supplemented with FACT-ES questions. 543 patients completed questionnaires at T1 and 454 patients (84%) at T2. Overall QoL and most functioning scales improved over time. The only clinically relevant and statistically significant difference between treatment types concerned insomnia; exemestane-treated patients reported more insomnia than tamoxifen-treated patients. Discrepancy was observed between QoL issue scores reported by the patients and adverse events reported by physicians. Certain QoL issues are treatment- and/or time-specific and deserve attention by health care providers. There is a need for careful inquiry into QoL issues by those prescribing endocrine treatment to optimize QoL and treatment adherence.

Introduction Vertical-banded gastroplasty, a technique that is commonly performed in the treatment of morbid obesity, represents a nonadjustable restrictive procedure which reduces the volume of the upper stomach by a vertical stapler line. In addition, a textile or silicone band restricts food passage through the stomach. Case presentation A 71-year-old woman presented with a severe gastric stenosis 11 years after vertical gastroplasty. We describe a side-to-side gastrogastrostomy as a safe surgical procedure to restore the physiological gastric passage after failed vertical-banded gastroplasty. Conclusion Occasionally, restrictive procedures for morbid obesity cannot be converted into an alternative bariatric procedure to maintain weight control. This report demonstrates that a side-to-side gastrogastrostomy is a feasible and safe procedure. PMID:18513454

The use of neuroleptic medicine in the treatment of schizophrenia is often predicated on the goal of eliminating psychotic symptoms. Use of neuroleptics, however, may produce unfortunate side effects. A case is presented which illustrates the time-limited use of neuroleptics. (JN)

Familiar shapes attract attention in figure-ground displays.

We report five experiments that explore the effect of figure-ground factors on attention. We hypothesized that figural cues, such as familiar shape, would draw attention to the figural side in an attentional cuing task using bipartite figure-ground displays. The first two experiments used faces in profile as the familiar shape and found a perceptual advantage for targets presented on the meaningful side of the central contour in detection speed (Experiment 1) and discrimination accuracy (Experiment 2). The third experiment demonstrated the figural advantage in response time (RT) with nine other familiar shapes (including a sea horse, a guitar, a fir tree, etc.), but only when targets appeared in close proximity to the contour. A fourth experiment obtained a figural advantage in a discrimination task with the larger set of familiar shapes. The final experiment ruled out eye movements as a possible confounding factor by replicating the RT advantage for targets on the figural side of face displays when all trials containing eye movements were eliminated. The results are discussed in terms of ecological influences on attention, and are cast within the framework of Yantis and Jonides's hypothesis that attention is exogenously drawn to the onset of new perceptual objects. We argue that the figural side constitutes an "object" whereas the ground side does not, and that figural cues such as shape familiarity are effective in determining which areas represent objects.

Background Metformin is widely known as an antidiabetic agent which has significant gastrointestinal side effects, but nightmares and abnormal dreams as its adverse reactions are not well reported. Case Presentation Herein we present a case of 56-year-old male patient with no known history of recurrent nightmares and sleep disorder, experiencing nightmare and abnormal dreams directly after consumption of 750 mg extended release metformin. He reported his dream as an unpleasant experience which awakened him at night with negative feelings. The nightmare only lasted for a night, but his dreams every night thereafter seemed abnormal. The dreams were vivid and indescribable. The disappearance and occurrence of abnormal dreams ensued soon after the drug was discontinued and rechallenged. The case was assessed using Naranjo Adverse Drug Reaction (ADR) probability scale and resulted as probable causality. Conclusion Metformin might be the underlying cause of nightmare and abnormal dreams in this patient. More studies are needed to confirm the association and causality of this findings. PMID:29581904

The generation of side force by distributed suction

This report provides an approximate analysis of the generation of side force on a cylinder placed horizontal to the flow direction by the application of distributed suction on the rearward side of the cylinder. Relationships are derived between the side force coefficients and the required suction coefficients necessary to maintain attached flow on one side of the cylinder, thereby inducing circulation around the cylinder and a corresponding side force.
