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

    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.

    For patients receiving intravenous immunoglobulin (IVIg), renal and hemolytic side effects are well recognized. However, there are very few data on the effects of chronic IVIg therapy. We retrospectively analyzed laboratory data on 166 patients who received IVIg for 12 months with a dose range of 0.441-2.58 g/kg/month, measuring changes in hematocrit and glomerular filtration (GFR) rates at 6 and 12 months. Of the 2,232 infusions, there were no incidents of clinical hemolysis. However, after 12 months of treatment, 21% of patients had a ≥3-g/dl decline in hematocrit and 10% had a ≥20% decline in GFR. No clinically significant hemolysis was observed in patients receiving chronic IVIg therapy. However, a significant number of patients had a decline in hematocrit and/or GFR while on therapy. This emphasizes the need for observation of hematologic and renal function in patients treated with chronic IVIg. Muscle Nerve 56: 1173-1176, 2017. © 2017 Wiley Periodicals, Inc.

  5. Recombinant Tissue Plasminogen Activator Induces Neurological Side Effects Independent on Thrombolysis in Mechanical Animal Models of Focal Cerebral Infarction: A Systematic Review and Meta-Analysis.

    Full Text Available Recombinant tissue plasminogen activator (rtPA is the only effective drug approved by US FDA to treat ischemic stroke, and it contains pleiotropic effects besides thrombolysis. We performed a meta-analysis to clarify effect of tissue plasminogen activator (tPA on cerebral infarction besides its thrombolysis property in mechanical animal stroke.Relevant studies were identified by two reviewers after searching online databases, including Pubmed, Embase, and ScienceDirect, from 1979 to 2016. We identified 6, 65, 17, 12, 16, 12 and 13 comparisons reporting effect of endogenous tPA on infarction volume and effects of rtPA on infarction volume, blood-brain barrier, brain edema, intracerebral hemorrhage, neurological function and mortality rate in all 47 included studies. Standardized mean differences for continuous measures and risk ratio for dichotomous measures were calculated to assess the effects of endogenous tPA and rtPA on cerebral infarction in animals. The quality of included studies was assessed using the Stroke Therapy Academic Industry Roundtable score. Subgroup analysis, meta-regression and sensitivity analysis were performed to explore sources of heterogeneity. Funnel plot, Trim and Fill method and Egger's test were obtained to detect publication bias.We found that both endogenous tPA and rtPA had not enlarged infarction volume, or deteriorated neurological function. However, rtPA would disrupt blood-brain barrier, aggravate brain edema, induce intracerebral hemorrhage and increase mortality rate.This meta-analysis reveals rtPA can lead to neurological side effects besides thrombolysis in mechanical animal stroke, which may account for clinical exacerbation for stroke patients that do not achieve vascular recanalization with rtPA.

    A study of psychoanalysis from the perspective of side effects reveals that its history was a succession of measures to deal with its own side effects. This, however, does not merely suggest that, as a treatment method, psychoanalysis is incomplete and weak: rather, its history is a record of the growth and development of psychoanalysis that discovered therapeutic significance from phenomena that were initially regarded as side effects, made use of these discoveries, and elaborated them as a treatment method. The approach of research seen during the course of these developments is linked to the basic therapeutic approach of psychoanalysis. A therapist therefore does not draw conclusions about a patient's words and behaviors from a single aspect, but continues to make efforts to actively discover a variety of meanings and values from them, and to make the patient's life richer and more productive. This therapeutic approach is undoubtedly one of the unique aspects of psychoanalysis. I discuss the issue of psychoanalysis and side effects with the aim of clarifying this unique characteristic of psychoanalysis. The phenomenon called resistance inevitably emerges during the process of psychoanalytic treatment. Resistance can not only obstruct the progress of therapy; it also carries the risk of causing a variety of disadvantages to the patient. It can therefore be seen as an adverse effect. However, if we re-examine this phenomenon from the perspective of transference, we find that resistance is in fact a crucial tool in psychoanalysis, and included in its main effect, rather than a side effect. From the perspective of minimizing the character of resistance as a side effect and maximizing its character as a main effect, I have reviewed logical organization, dynamic evaluation, the structuring of treatment, the therapist's attitudes, and the training of therapists. I conclude by stating that psychoanalysis has aspects that do not match the perspective known as a side

    Medications which bind to opioid receptors are increasingly being prescribed for the treatment of multiple and diverse chronic painful conditions. Their use for acute pain or terminal pain is well accepted. Their role in the long-term treatment of chronic noncancer pain is, however, controversial for many reasons. One of the primary reasons is the well-known phenomenon of psychological addiction that can occur with the use of these medications. Abuse and diversion of these medications is a growing problem as the availability of these medications increases and this public health issue confounds their clinical utility. Also, the extent of their efficacy in the treatment of pain when utilized on a chronic basis has not been definitively proven. Lastly, the role of opioids in the treatment of chronic pain is also influenced by the fact that these potent analgesics are associated with a significant number of side effects and complications. It is these phenomena that are the focus of this review. Common side effects of opioid administration include sedation, dizziness, nausea, vomiting, constipation, physical dependence, tolerance, and respiratory depression. Physical dependence and addiction are clinical concerns that may prevent proper prescribing and in turn inadequate pain management. Less common side effects may include delayed gastric emptying, hyperalgesia, immunologic and hormonal dysfunction, muscle rigidity, and myoclonus. The most common side effects of opioid usage are constipation (which has a very high incidence) and nausea. These 2 side effects can be difficult to manage and frequently tolerance to them does not develop; this is especially true for constipation. They may be severe enough to require opioid discontinuation, and contribute to under-dosing and inadequate analgesia. Several clinical trials are underway to identify adjunct therapies that may mitigate these side effects. Switching opioids and/or routes of administration may also provide benefits

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

    A firm understanding of the preliminary assessment of a patient with neurological disorders is needed for ensuring optimal patient outcomes. The purpose of this study is to evaluate the effects of using e-learning on neurologic assessment knowledge, ability, and self-confidence among nurses. This study used a non-equivalent control group pretest-posttest design. Nurses working in the neurology and neurosurgery wards, Republic of Korea PARTICIPANTS: A convenience sample of 50 nurses was assigned to either the experimental group (n=24) or the control group (n=26). The experimental group participated in the self-directed e-learning program related to neurologic assessment, and control group underwent self-directed learning with handout. Knowledge, ability, and self-confidence were measured at pretest and posttest. There were no significant differences in knowledge (U=270, p=0.399) and self-confidence (U=241.5, p=0.171) between the two groups. Nurses in the experimental group showed higher neurologic assessment ability compared with those in the control group (U=199, p=0.028). Self-directed neurologic assessment e-learning induced improvement in the neurologic assessment ability among nurses. Self-directed e-learning can be applied for improving competencies in neurologic assessment. Copyright © 2017 Elsevier Ltd. All rights reserved.

    2012-11-01

    Finasteride has been associated with sexual side effects that may persist despite discontinuation of the medication. In a clinical series, 20% of subjects with male pattern hair loss reported persistent sexual dysfunction for ≥6 years, suggesting the possibility that the dysfunction may be permanent. These subjects also reported a wide range of symptoms including changes in cognition, ejaculate quality, and genital sensation. Other medications have been associated with irreversible neurological effects, such as phenothiazines with tardive dyskinesias. To prospectively study whether the persistent sexual side effects associated with finasteride resolve or endure over time. Subjects (N = 54) with persistent sexual side effects associated with finasteride were reassessed after 9-16 months (mean 14 months). All subjects were otherwise healthy young men without any baseline sexual dysfunction, medical conditions, psychiatric conditions, or use of oral prescription medications prior to taking finasteride for male pattern hair loss. Scores from the Arizona Sexual Experience Scale (ASEX). The participation rate was 81%. At reassessment persistent sexual side effects continued to be present in 96% of subjects. According to the ASEX scores, 89% of subjects met the definition of sexual dysfunction. Neither the length of finasteride use nor the duration of the sexual side effects correlated to changes in scores of sexual dysfunction. In most men who developed persistent sexual side effects (≥3 months) despite the discontinuation of finasteride, the sexual dysfunction continued for many months or years. Although several rat studies have shown detrimental changes to erectile function caused by 5 alpha reductase inhibitors, the persistent nature of these changes is an area of active research. Prescribers of finasteride and men contemplating its use should be made aware of the potential adverse medication effects. © 2012 International Society for Sexual Medicine.

    Intense pulsed light (IPL) has been successfully used as an efficient hair removal system; however, possible side-effects have been not specifically addressed in the literature. To assess all possible side-effects after IPL hair removal in a series of 49 females with facial hirsutism during a total of 390 treatment sessions of IPL photodepilation. Immediate post-treatment clinical, photography evaluation, and a two-month post-treatment questionnaire were done in 49 females with facial hirsutism submitted to photodepilation with an IPL source (EpiLight trade mark, ESC, Israel). Side-effects observed were: transient erythema (n = 30), late evanescent erythema (n = 3), mild pain (n = 43), moderate pain (n = 6), crust formation (n = 9), superficial burning (n = 1), isolated vesicles (n = 3), transient hyperpigmentation (n = 8), transient hypopigmentation (n = 1), paradoxical effect (n = 5), persistent local heat sensation (n = 1), and minimal scar (n = 1). Even though common, most side-effects secondary to IPL photodepilation are mild and transient. Permanent side-effects such as scars are unlikely but they may occur. Growth of new, fine and dark hair may be seen in untreated areas in close proximity to the treatment area, especially in the neck, a side-effect that is reported for the first time in the literature.

    2016-12-01

    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.

  20. The Social Side Effects of Acetaminophen

    Science.gov (United States)

    Mischkowski, Dominik

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

  1. Microbiota and neurologic diseases: potential effects of probiotics.

    Umbrello, Giulia; Esposito, Susanna

    2016-10-19

    The microbiota colonizing the gastrointestinal tract have been associated with both gastrointestinal and extra-gastrointestinal diseases. In recent years, considerable interest has been devoted to their role in the development of neurologic diseases, as many studies have described bidirectional communication between the central nervous system and the gut, the so-called "microbiota-gut-brain axis". Considering the ability of probiotics (i.e., live non-pathogenic microorganisms) to restore the normal microbial population and produce benefits for the host, their potential effects have been investigated in the context of neurologic diseases. The main aims of this review are to analyse the relationship between the gut microbiota and brain disorders and to evaluate the current evidence for the use of probiotics in the treatment and prevention of neurologic conditions. Overall, trials involving animal models and adults have reported encouraging results, suggesting that the administration of probiotic strains may exert some prophylactic and therapeutic effects in a wide range of neurologic conditions. Studies involving children have mainly focused on autism spectrum disorder and have shown that probiotics seem to improve neuro behavioural symptoms. However, the available data are incomplete and far from conclusive. The potential usefulness of probiotics in preventing or treating neurologic diseases is becoming a topic of great interest. However, deeper studies are needed to understand which formulation, dosage and timing might represent the optimal regimen for each specific neurologic disease and what populations can benefit. Moreover, future trials should also consider the tolerability and safety of probiotics in patients with neurologic diseases.

    The risk of sepsis with a hip or knee implant does not seem to be increased by prior joint injections, as long as the injection and surgery are separated by at least two months. Calcifications have been reported after intradiscal injection in the coccygeal region for coccydynia. Complete rest for 24 hours after injection of triamcinolone hexacetonide into the knee had no effect on systemic diffusion of the product. Patients infected by HIV who are treated with ritonavir are at much greater risk for Cushing syndrome after epidural injection. Problems with menstruation after corticosteroid injection seem to be related to a transient decrease in estradiol levels, without alterations in FSH and LH levels. The risk of central serous chorioretinopathy and acute necrosis of the retina after injection is not known, even by ophthalmologists. Transient dysphonia occurs in 12% of patients receiving corticosteroid injections. The impressive Tachon's syndrome seems to be the venous counterpart to Nicolau's syndrome for arteries. Injections into C1-C2 should be abandoned because of the neurological risks. Since serious neurological events after foraminal injections could be the result of an overly fast injection into the arterialized radicular veins rather than in the arteries, only slow injections with products having a low risk of embolism or vascular complications should be allowed. Dexamethasone-based preparations seem to contain no particles or crystals, and have not induced any neurological accidents in various animal models, even after direct administration into vertebral or carotid arteries.

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

    The use of benzodiazepine anxiolytics and hypnotics continues to excite controversy. Views differ from expert to expert and from country to country as to the extent of the problem, or even whether long-term benzodiazepine use actually constitutes a problem. Although as a class benzodiazepines act rapidly and are well tolerated, their use presents clinical issues such as dependence, rebound anxiety, memory impairment, and discontinuation syndrome. The aim of this article is to review literature regarding different side effects associated with treatment with benzodiazepines - effects on cognition, treatment with benzodiazepines during pregnancy, dependence on benzodiazepines and risk of falling. Literature research included structured searches of Medline and other publications on the subject of treatment with benzodiazepines, particularly effects on cognition, risk of falls, benzodiazepine dependence and treatment with benzodiazepines during pregnancy. Results of investigations have revealed different side effects associated with treatment with benzodiazepines. Previous investigations showed that treatment with benzodiazepines may induce anterograde amnesia. Also, previous studies confirmed occurrence of physical dependence in high percentage of patients in long term treatment with benzodiazepines at therapeutic dosages. Some investigation suggested higher risk of oral cleft, the floppy infant syndrome, or marked neonatal withdrawal symptoms when using benzodiazepines during pregnany. Investigations have shown increased risk of falling in elderly persons taking benzodiazepines.

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

  16. Unintended effects of orphan product designation for rare neurological diseases.

    2012-10-01

    Since the introduction of the Orphan Drug Act in 1983, designed to promote development of treatments for rare diseases, at least 378 orphan drugs have been approved. Incentives include financial support, tax credits, and perhaps most importantly, extended market exclusivity. These incentives have encouraged industry interest and accelerated research on rare diseases, allowing patients with orphan diseases access to treatments. However, extended market exclusivity has been associated with unacceptably high drug costs, both for newly developed drugs and for drugs that were previously widely available. We suggest that a paradoxical effect of orphan product exclusivity can be reduced patient access to existing drugs. In addition, the costs of each new drug are arguably unsustainable for patients and for the American health care system. Of all the specialties, neurology has the third highest number of orphan product designations, and neurological diseases account for at least one-fifth of rare diseases. Citing the use of tetrabenazine for chorea in Huntington disease, adrenocorticotropic hormone for infantile spasms, and enzyme replacement therapy with alglucosidase alpha for Pompe disease, we highlight these paradoxical effects.

    Proton pump inhibitors (PPIs) are one of the most frequently prescribed medications across the globe. Esomeprazole is the S-isomer of omeprazole, and it is currently the most widely prescribed PPI. The safety profile of esomeprazole is extremely favorable with only minor side effects, like headache and diarrhea, that are encountered in day to day practice. We report a case of a young female with symptoms of gastroesophageal reflux disease who developed galactorrhea after starting esomeprazole therapy. Resolution of galactorrhea after stopping the drug and self-rechallenge by the patient herself with reappearance of galactorrhea confirmed the culprit to be esomeprazole only. We postulate that esomeprazole may have a mild inhibitory effect on CYP3A4, which leads to decreased metabolism of estrogen, thereby increasing serum estrogen levels. Estrogen causes stimulation and production of prolactin release, which results in development of galactorrhea. This is the first case of esomeprazole induced galactorrhea, to the best of our knowledge.

    SUMMARY Research on animal models demonstrates that fetal cocaine exposure results in neurologic deficits in memory and learning. Although drug effects on human infants are difficult to separate from other environmental influences of a drug-using lifestyle, studies suggest that infants exposed to cocaine in utero have reduced growth, delays in sensory-motor development, attentional deficits, and depressed responsivity to social stimulation. Standard interventions to promote behavioral state regulation in affected infants may be helpful when parents are capable of participating. PMID:25688173

    Full Text Available Carbon monoxide poisoning (COP is one of the most common causes of mortality and morbidity due to poisoning in all over the world. Although the incidence of COP has not been known exactly in the childhood, almost one-third of CO exposures occurred in children. The data regarding COP in children are inconclusive. Children may be more vulnerable to CO exposure than adults as a result of their high respiration and metabolic rates, high oxygen metabolism, and immature central nervous system. Recent researches proposed new theories about neurological effects of CO toxicity. The clinical presentations associated acute COP may be various and nonspecific. Unrecognized CO exposure may lead to significant morbidity and mortality. CO exposed children often become symptomatic earlier, and recover more rapidly, than similarly CO exposed adults. Mild clinical signs and symptoms associated with COP are headache, dizziness, weakness, lethargy, and myalgia; however, severe signs and symptoms such as blurred vision, syncope, convulsion, coma, cardiopulmonary arrest and death can also accompany with COP. Neurologic manifestations can include altered mental status at different degrees, neck stiffness, tremor, ataxia, and positive Babinski's sign. Delayed neurologic sequels (DNS of COP might be seen in children like adults. DNS symptoms and signs in children include memory problems, mental retardation, mutism, fecal and urinary incontinence, motor deficits, facial palsy, psychosis, chronic headache, seizures, and epilepsy. After CO exposure children must be cared to detect and treat DNS. Although hyperbaric oxygen therapy (HBOT is reported to prevent development of DNS, its indications, application duration and procedures are controversial in both of the children and adults. Although their predictive values are limited, exposing to CO more than eight hours and suffering from CO-induced coma, cardiac arrest, lactic acidosis, high COHb levels, and pathologic findings

    On the basis of more than 35 cases from literature a survey of clinical and paraclinical findings, diagnostic criteria, differential diagnosis, therapy and prognosis of the pulmonary reaction evoked by gold is given. The first symptoms mostly appear within the initial phase of the treatment, after several weeks to months. Unexpectedly increasing dyspnoea, weakness, cough and feeling of sickness in patients who are treated with gold salts are warning signals which refer to the possibility of a lung injury by gold. The differential-diagnostic demarcation from rheumatoid lung, a rare extraarticular manifestation of the rheumatoid arthritis, may render difficulties. The latter, however, usually refers to a slower progressing, is not or only incompletely able to involution and scarcely reacts to cortisonoids. The gold-conditioned pulmonary changes in most cases completely involve after a well-timed finish of the treatment with the gold-preparation. Cortisonoids are given for the acceleration of the remission. The prognosis is in general good. However, it depends on the fact, how long the gold treatment is still continued after the appearance of the pulmonary side-effect.

    The use of hypofractionated radiotherapy regimens is becoming more widely recognized in the palliation of non-small cell lung carcinoma (NSCLC). Anecdotal reports of chest pain, rigors and fevers in the hours that follow radiotherapy led us to perform a survey estimating the frequency and severity of these symptoms following treatment to the thorax. One hundred and eighteen patients completed questionnaires 24 hours after palliative radiotherapy treatment; 84 were male. The median age was 67 years. One hundred and seven had histologically confirmed NSCLC. A parallel opposed technique was used in 113 patients. Doses ranged from 8 Gy in a single fraction to 60 Gy in 30 fractions. Chest pain was reported by 54 (45.8%) patients after the first radiotherapy fraction; in 42 it commenced within 12 hours of treatment. The pain varied in site, nature and duration; on 23 occasions, it lasted under 2 hours. Systemic symptoms (rigors, sweating, fevers) were documented on 43 questionnaires, starting within 12 hours of treatment in 33 patients and on 30 occasions lasting less than 2 hours. Chest pain and systemic symptoms occurred together in 28 patients. Only 49 (41.5%) patients reported no immediate side effects. We conclude that patients receiving palliative radiotherapy for bronchial carcinoma often develop significant symptoms in the hours following treatment. The timing and duration suggest a relationship with the radiotherapy, and we feel that patients should be warned of the possible occurrence of these symptoms.

    . Fifty patients were included in the study. There were 18 men and 32 women. The mean age was 53.5 15.9 years [22 - 77], the mean period of treatment was 24 30.5 months [1 - 127] and 52% of the patients received concomitant medication with anxiolitic or hypnotic drug(s). The percentage of patients who reported at least one side effect was significantly higher for the UKU scale than for SN (84% vs 58%, p<0.01). The ratio between SN and UKU scale scores was 2/3. A similar pattern was found for the total number of side effects (n=177 vs n=47, p<0.001). The ratio between the total number of side effects for the SN and UKU scale was 1/4. The side effects were divided into five subgroups: psychiatric, neurovegetative, sexual, neurological and others. In all these subgroups, the number of side effects reported was significantly higher when the UKU scale was used than when SN was used. The values were as follows: psychiatric (n=44 vs n=15, p<0.001), neurovegetative (n=59 vs n=15, p<0.001), sexual (n=36 vs n=10, p<0.001), neurological (n=11 vs n=2, p<0.001) and other side effects (n=27 vs n=5, p<0.001). Nineteen side effects were only reported when SN was used (for example: dry eyes, incompatibility with alcohol, euphoria...). Twenty-four side effects were only reported when the UKU scale was used (for example: increased libido, loss of bodyweight...). The side effects had no impact on daily life in most of 80% of the patients; there was no significant difference between the patient's assessment of the discomfort caused by side effects and the clinician's assessment. In 90% of cases, the side effects did not lead to any change in the treatment. The findings of this study show that the collection of data regarding side effects depends on the assessment tool used: the number of side effects reported was significantly higher when the UKU scale was used than when SN was used. However, this finding must viewed with caution, because it has been showed that checklists can induce symptoms

    2008-01-01

    The safety and tolerability of antidepressants have improved considerably over the past two decades, Nevertheless, antidepressant side effects are still common and problematic. The majority of patients treated with contemporary agents experience one or more bothersome side effects. These side effects often create barriers to achieving depressive remission, as well as to preventing relapse and recurrence. Clinicians tend to underestimate the prevalence of side effects, and as many as one quarter of patients discontinue their antidepressants because of difficult-to-tolerate side effects; others may continue on antidepressant therapy but experience diminished quality of life related to troublesome side effects. This article reviews the prevalence of side effects, the impact of side effects on treatment adherence, and methodological issues including the challenge of distinguishing side effects from residual depressive symptoms, discontinuation effects, and general medical problems. In addition, we address the most common side effects such as sexual dysfunction, gastrointestinal problems, sleep disturbance, apathy, and fatigue, and offer strategies for management that may help patients achieve optimal response to pharmacotherapy.

    2008-08-05

    Mental retardation is one of the most prevalent neurologic disorders globally. Surveys in high-income countries show 3 to 5 per 1,000 with severe intellectual disability, i.e., IQ below 55. Estimates from developing countries, however, have found prevalence rates from 5 to as much as 22 per 1,000. Protein-energy malnutrition, dietary micronutrient deficiencies, environmental toxins, and lack of early sensory stimulation or the ability to profit from it may contribute to neurodevelopmental disabilities. Tropical diseases such as parasitosis with resultant anemia, malaria, and other infections are major contributory causes. Reduction of poverty and its effects would reduce the present and future burden of mental retardation and cognitive dysfunction, especially in developing countries.

    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...

    To define medical student goals in the neurology clerkship and explore the association between goal setting and student performance, clerkship satisfaction, self-directed learning (SDL), and interest in neurology. A 4-year prospective study of consecutive second- to fourth-year medical students rotating through a required 4-week neurology clerkship was conducted. A goal-generating cohort (first 2 years) was enrolled to describe the breadth of student-derived goals. A goal-evaluating cohort (second 2 years) was used to evaluate the frequency of goal achievement and assess associations with performance (e.g., National Board of Medical Examiners [NBME], examination), satisfaction, and SDL behaviors (both based on 5-point Likert scale). Of 440 evaluable students, 201 were goal-generating and 239 goal-evaluating. The top 3 goals were (1) improvement in neurologic examination, (2) understanding neurologic disease, and (3) deriving a differential diagnosis. More than 90% (n = 216/239) of students reported achieving goals. Achievers reported significantly higher clerkship satisfaction (4.2 ± 0.8 vs. 2.8 ± 1.0, p neurology (71% vs. 35%, p = 0.001), and higher observed tendency toward SDL (4.5 ± 0.5 vs. 4.1 ± 0.8, p neurology clerkship. Goal achievers had better adjusted standardized test scores, higher satisfaction, and greater tendency toward SDL. This student-generated, goal-setting program may be particularly appealing to clinicians, educators, and researchers seeking resource-lean mechanisms to improve student experience and performance in the clinical clerkships. © 2015 American Academy of Neurology.

Complete recovery occurred following discontinuation of the drug. A brain computed tomography scan excluded intracranial hemorrhage and the laboratory results confirmed that no exacerbation of infection or electrolyte imbalances were present. During the aphasic episode, the patient’s condition did not deteriorate and no new neurological symptoms occurred. We suspect that the occurrence of aphasia was directly due to an adverse reaction to quetiapine. To our knowledge, this is the first case report of reversible, global aphasia as a side effect of quetiapine. We propose that this occurrence of aphasia may be due to the action of quetiapine as a dopamine receptor antagonist. Clinicians should use quetiapine with caution, especially in elderly patients. On observation of aphasia, a review of the patient’s medical history is required to assess for the usage of quetiapine. Keywords: aphasia, quetiapine, insomnia, delirium

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

    LENUS (Irish Health Repository)

    Bates, John J

    2012-02-03

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

  18. Building the process-drug–side effect network to discover the relationship between biological Processes and side effects

    Science.gov (United States)

    2011-01-01

    Background Side effects are unwanted responses to drug treatment and are important resources for human phenotype information. The recent development of a database on side effects, the side effect resource (SIDER), is a first step in documenting the relationship between drugs and their side effects. It is, however, insufficient to simply find the association of drugs with biological processes; that relationship is crucial because drugs that influence biological processes can have an impact on phenotype. Therefore, knowing which processes respond to drugs that influence the phenotype will enable more effective and systematic study of the effect of drugs on phenotype. To the best of our knowledge, the relationship between biological processes and side effects of drugs has not yet been systematically researched. Methods We propose 3 steps for systematically searching relationships between drugs and biological processes: enrichment scores (ES) calculations, t-score calculation, and threshold-based filtering. Subsequently, the side effect-related biological processes are found by merging the drug-biological process network and the drug-side effect network. Evaluation is conducted in 2 ways: first, by discerning the number of biological processes discovered by our method that co-occur with Gene Ontology (GO) terms in relation to effects extracted from PubMed records using a text-mining technique and second, determining whether there is improvement in performance by limiting response processes by drugs sharing the same side effect to frequent ones alone. Results The multi-level network (the process-drug-side effect network) was built by merging the drug-biological process network and the drug-side effect network. We generated a network of 74 drugs-168 side effects-2209 biological process relation resources. The preliminary results showed that the process-drug-side effect network was able to find meaningful relationships between biological processes and side effects in an

    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. 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. 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). Among patients with epilepsy, addressing medication side effects at every visit does not appear to increase patient-reported medication adherence.

  5. Side Flow Effect on Surface Generation in Nano Cutting

    2017-05-01

    The side flow of material in nano cutting is one of the most important factors that deteriorate the machined surface quality. The effects of the crystallographic orientation, feed, and the cutting tool geometry, including tool edge radius, rake angle and inclination angle, on the side flow are investigated employing molecular dynamics simulation. The results show that the stagnation region is formed in front of tool edge and it is characterized by the stagnation radius R s and stagnation height h s . The side flow is formed because the material at or under the stagnation region is extruded by the tool edge to flow to the side of the tool edge. Higher stagnation height would increase the size of the side flow. The anisotropic nature of the material which partly determines the stagnation region also influences the side flow due to the different deformation mechanism under the action of the tool edge. At different cutting directions, the size of the side flow has a great difference which would finally affect the machined surface quality. The cutting directions of {100} , {110} , and {110} are beneficial to obtain a better surface quality with small side flow. Besides that, the side flow could be suppressed by reducing the feed and optimizing the cutting tool geometry. Cutting tool with small edge radius, large positive rake angle, and inclination angle would decrease the side flow and consequently improve the machined surface quality.

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

    Patients' attitudes toward side effects of antidepressants are likely to differ according to gender, which has not yet been fully addressed in the literature. From the 228,310 registrants, 1,305 participants who had received antidepressant drugs within the past year were identified with the Yahoo Japan research monitor through four-step screening procedures. Participants were asked as to which side effect(s) they had experienced, whether they had reported those side effects to their physicians, and whether they had taken any action to counteract them. The questionnaire was completed by 1,187 participants. Side effects were reported in 73.4% of the participants; the prevalence of self-reported side effects was significantly higher in men than women (80.4% vs. 68.3%, P <0.05). The percentage of participants who reported side effects to their physicians widely differed depending on the nature of their experience, ranging from 45.7% to 89.9%; the lowest was for sexual dysfunction. The percentage of participants who had taken any action to relieve side effects varied among side effects from 26.3% for sexual dysfunction to 89.5% for dry mouth. Moreover, a lower percentage of women had reported sexual dysfunction to physicians (36.6% vs. 60.7%, P <0.05) and had taken any action to counteract the problem (19.8% vs. 36.9%, P <0.05). Given that patients experienced with antidepressants are likely to be reluctant to report sexual side effects, physicians should be cognizant of the potential presence of sexual dysfunction in patients who are taking antidepressants, especially for women.

  10. Evaluation of vehicle side airbag effectiveness in Victoria, Australia.

    D'Elia, Angelo; Newstead, Stuart; Scully, Jim

    2013-05-01

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

    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.

    2011-01-01

    Several types of gastrointestinal complications can occur during treatment with targeted therapies: diarrhoea, nausea and vomiting, abnormalities in hepatic and pancreatic profiles, etc. Gastrointestinal problems in targeted therapy can have a significant impact on the general status of patients, their weight and their adherence to the treatment. The prevention, screening and rapid treatment of these side-effects are essential elements of patient care and can limit the associated dose reductions and loss of therapeutic benefit. In the case of diarrhoea, treatment must be started at the onset of grade 1 or 2 diarrhoea (four to six stools per day), with loperamide or racecadotril. Treatment with targeted therapy must be stopped if there is diarrhoea of grade 3 or 4 (more than six stools per day). In the case of nausea/vomiting or burning pain in the oesophagus, symptomatic treatment without stopping the targeted therapy is recommended. Biological assessment including transaminases, total and conjugated bilirubin should be prescribed before treatment initiation with targeted therapy. An elevation in alkaline phosphatases without elevation of transaminases suggests primarily the existence of hepatic metastases. In the event of worsening of the hepatic profile, if ALT greater than 5N, treatment must be stopped and specialist advice sought. Copyright © 2011 Société Française du Cancer.

  14. Measuring contraceptive efficacy and side effects.

    Science.gov (United States)

    Sivin, I

    To assess effectiveness of contraceptives, one reports all pregnancies during use. Multiple and single decrement life-table pregnancy rates computed from these reports constitute the fundamental measures of effectiveness in clinical trials. Minimally biased evaluation of a new method requires a randomized, double-blind (or its nearest semblance), multicentered study of sexually active women. New contraceptives are studied in special, volunteer populations. Evaluation of marketed contraceptives implies broader-gauged representation, larger numbers and longer time frames. Prospective studies, like clinical trials, should include several methods, and may use subsamples for case-control analysis of risk. Well-designed and executed multicentered, prospective studies, nevertheless, may represent specially selected populations. Risk-benefit analyses based on findings from selected populations require careful scrutiny. Although the most persuasive estimates of effectiveness derive from national, representative samples, moderately large samples in the USA have not been able to distinguish among products within a class. Formidable problems of recall are present in household surveys. In the United Kingdom, Europe and North America, analysis of risks and benefits may be enriched by better utilization of the data collection and record linkage resources of national health statistics systems.

    Shacklock, Emma; Gemmell, Andrew; Hollister, Nigel

    2017-11-01

    Fat embolism syndrome is a serious multi-system pathology which classically affects the respiratory system, neurological system and causes a petechial rash. We present the case of a 20-year-old farmer who developed fat embolism syndrome following a traumatic femoral fracture. Features developed within 24 h of injury and necessitated a prolonged stay in Intensive Care. He exhibited significant signs of cerebral fat embolism syndrome including coma and seizures but went on to make full functional recovery. Magnetic resonance imaging is the recommended imaging modality for patients with suspected cerebral fat embolism. In this case, computerised tomography was inconclusive, but magnetic resonance imaging demonstrated the "starfield pattern" of multiple high signal foci on a dark background. Supportive treatment of fat embolism syndrome is required in an appropriate setting, such as High Dependency or Intensive Care, for patients at risk of hypoxia or neurological deterioration. Despite major neurological involvement of fat embolism syndrome, full recovery is described by several cases including ours.

  7. Soy and phytoestrogens: possible side effects

    Directory of Open Access Journals (Sweden)

    2014-12-01

    Full Text Available [english] Phytoestrogens are present in certain edible plants being most abundant in soy; they are structurally and functionally analogous to the estrogens. Phytoestrogens have been applied for compensation of hormone deficiency in the menopause. At the same time, soy products are used in infant food and other foodstuffs. Furthermore, soy is applied as animal fodder, so that residual phytoestrogens and their active metabolites such as equol can remain in meat and influence the hormonal balance of the consumers. There have been only singular reports on modified gender-related behavior or feminization in humans in consequence of soy consumption. In animals, the intake of phytoestrogens was reported to impact fertility, sexual development and behavior. Feminizing effects in humans can be subtle and identifiable only statistically in large populations.

    We present a case of a 64-year-old man with Crohn's disease who developed parkinsonism after starting treatment with infliximab (Remicade). The patient had a 30-year history of Crohn's disease with previous surgical procedures and treatment with methotrexate. Treatment was augmented with infliximab, and 3 days after the first dose of 400 mg, a resting tremor began in the left leg. Over 4 months, symptoms progressed and now involved the right leg as well as both hands. There was no clinical effect of infliximab treatment, and the treatment was withdrawn 4 months later. The patient then experienced gradual, but continual, improvement of the resting tremor after withdrawal of infliximab. To the best of our knowledge, this is the first case report describing a patient developing parkinsonism after starting treatment with infliximab, with symptoms remitting on discontinuation. 2016 BMJ Publishing Group Ltd.

    To evaluate information on the practice and associated ill effects of sword swallowing. Letters sent to sword swallowers requesting information on technique and complications. Membership lists of the Sword Swallowers' Association International. 110 sword swallowers from 16 countries. We had information from 46 sword swallowers. Major complications are more likely when the swallower is distracted or swallows multiple or unusual swords or when previous injury is present. Perforations mainly involve the oesophagus and usually have a good prognosis. Sore throats are common, particularly while the skill is being learnt or when performances are too frequent. Major gastrointestinal bleeding sometimes occurs, and occasional chest pains tend to be treated without medical advice. Sword swallowers without healthcare coverage expose themselves to financial as well as physical risk. Sword swallowers run a higher risk of injury when they are distracted or adding embellishments to their performance, but injured performers have a better prognosis than patients who suffer iatrogenic perforation.

    The effects on operational proficiency of the antimotion sickness drugs scopolamine, promethazine and d-amphetamine are tested using a computerized pursuit meter. Proficiency is not significantly affected by oral doses of 0.25 mg or 0.50 mg scopolamine but is descreased by oral or I.M. doses of 25 mg promethazine. The performance decrement associated with 25 mg oral promethazine is prevented when combined with 10 mg oral d-amphetamine. The combination of 25 mg I.M. promethazine, 25 mg oral promethazine and 10 mg d-amphetamine produces less performance decrement than oral or I.M. doses of promethazine alone, though more performance decrement than a placebo. I.M. promethazine is adsorbed slowly and consequently may provoke drowsiness.

    Multiple studies have identified consumers' difficulty correctly interpreting risk information provided about prescription drugs, whether in printed format or online. This study's purpose was to explore whether consumers can distinguish between prescription drug precautions and side effects presented on brand-name drug websites. Participants (n=873) viewed fictitious drug websites that presented both precautions and side effects for one of four drugs, and they completed a survey assessing recall and comprehension. We coded open-ended recall data to identify whether drug precautions were mentioned and, if so, how they were interpreted. Approximately 15% of participants mentioned at least one drug precaution. The majority (59.7%) misinterpreted precautions as potential side effects. Participants who misinterpreted precautions rated the drugs as significantly more likely to cause side effects than participants who accurately interpreted the precautions. Age, education, literacy, and other factors did not appear to predict precaution interpretation. At least some consumers are likely to interpret precautions on drug websites as potential side effects, which might affect consumer preferences, treatment decisions, and medication safety. Healthcare providers should be aware of this potential confusion, assess patients' understanding of precautions and potential side effects, and address any misunderstandings.

    Brucellosis is highly endemic in Turkey and doxycycline is commonly used for its treatment. The present study aimed at documenting the cutaneous side effects of doxycycline in pediatric brucellosis patients in Turkey. Pediatric patients with brucellosis that were treated between February 2014 and January 2016 were analyzed retrospectively, and those that developed doxycycline-related cutaneous side effects were identified. Demographic data, epidemiological history, physical examination findings, laboratory test results, anti-brucellosis treatment regimen, duration of follow up and outcome were recorded. Among the 189 brucellosis patients, 141 treated with doxycycline plus rifampicin. Seven patients (5%) (two female and five male) developed doxycycline-related cutaneous side effects. Mean duration of treatment before the onset of cutaneous side effects was 9.5 weeks. Doxycycline therapy was continued in five of these patients and was changed in two patients. In the patients that continued to receive doxycycline the cutaneous side effects gradually improved. Cutaneous side effects of doxycycline should always be a consideration, especially in regions in which brucellosis is endemic and doxycycline is commonly used to treat it.

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

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

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

    Aortic manipulation and particle embolization have been identified to cause cerebrovascular accidents in cardiac surgery. Recent data suggest that left-hemispheric cerebrovascular accident (right-sided symptoms) is more common, and this has been interpreted as being caused by aortic cannula stream jets. Our aim was to evaluate symptoms of cerebrovascular accident and side differences from a retrospective statistical analysis. During a 2-year period, 2641 consecutive cardiac surgery cases were analyzed. Patients positive for cerebrovascular accident were extracted from a database designed to monitor clinical symptoms. A protocol was used to confirm symptom data with the correct diagnosis in patient records. Patients were subdivided into 3 groups: control, immediate cerebrovascular accident, and delayed cerebrovascular accident. Among pooled patients, immediate and delayed cerebrovascular accidents were 3.0% and 0.9%, respectively. The expected predisposing factors behind immediate cerebrovascular accidents were significant, although the type of operation affected this search. Aortic quality was a strong predictor ( P cerebrovascular accident was unaffected by surgery group. Left-sided symptoms of immediate cerebrovascular accident were approximately twice as frequent ( P = .016) as on the contralateral side. This phenomenon was observed for pooled patients and for isolated coronary bypass procedures (n = 1882; P = .025). Immediate cerebrovascular accident and aortic calcifications are linked. The predominance of left-sided symptoms may suggest that aortic manipulation and anatomic mechanisms in the aortic arch are more likely to cause cerebrovascular accidents than effects from cannula stream jets.

Recent studies have pointed out their effect on weight gain and increased visceral adiposity as they induce metabolic syndrome. Patients receiving SGAs often need to be treated with other substances to counteract metabolic side effects. In this paper, we point out the possible protective effect of add-on melatonin treatment in preventing, mitigating, or even reversing SGAs metabolic effects, improving quality of life and providing safer long-term treatments in pediatric patients. Melatonin is an endogenous indolamine secreted during darkness by the pineal gland; it plays a key role in regulating the circadian rhythm, generated by the suprachiasmatic nuclei (SCN of the hypothalamus, and has many other biological functions, including chronobiotic, antioxidant and neuroprotective properties, anti-inflammatory and free radical scavenging effects, and diminishing oxidative injury and fat distribution. It has been hypothesized that SGAs cause adverse metabolic effects that may be restored by nightly administration of melatonin because of its influence on autonomic and hormonal outputs. Interestingly, atypical anti-psychotics (AAPs can cause

    Patients' coping methods to palliate side effects of antidepressants have not been reported in the literature. Through an Internet survey, 856 participants who were diagnosed with depression and receiving antidepressants were recruited to report on the methods of coping with side effects. They were asked which side effect(s) they experienced and to write freely about the way they tried to counteract these effects. We classified active coping methods into the following sub-types: adjustment of prescriptions, additional medication, complementary therapy, consultation with physicians, and daily relief. The prevalence of active coping differed across side effects (from 26.7%, sexual dysfunction, to 89.5%, dry mouth). Events with a lower percentage of active coping were more likely to be managed with "adjustment of prescriptions": (sexual dysfunction, 41.9%; fatigue, 36.8%; sweating, 20.0%; tremor, 42.5%; and somnolence, 31.8%). Further, a strong negative correlation was found between the percentage of participants reporting an adjustment of prescription and that reporting an active coping (r=-0.907, pnegative methods such as vomiting for nausea and weight gain and drinking alcohol for insomnia. Sampling of subjects were biased due to an Internet survey and diagnosis of depression and experience of side effects were self-reported. Patients with depression use various ways in alleviating antidepressants side effects. Some effects such as sexual dysfunction and fatigue may not be amenable to subjective coping efforts and others are sometimes managed inappropriately, which warrants a prudent attention.

    Targeted therapy in oncology consists of drugs that specifically interfere with abnormal signaling pathways that are dysregulated in cancer cells. Tyrosine kinase inhibitors (TKIs) take advantage of unique oncogenes that are activated in certain types of cancer, and also target common mechanisms of growth, invasion, metastasis, and angiogenesis. However, many kinase inhibitors for cancer therapy are somewhat nonselective, and most have additional mechanisms of action at the cellular level, which are not completely understood. The use of these agents has increased our knowledge of important side effects, of which the practicing clinician must be aware. Recently, proposed endocrine-related side effects of these agents include alterations in thyroid function, bone metabolism, linear growth, gonadal function, fetal development, and glucose metabolism, and adrenal function. This review summarizes the most recent data on the endocrine side effects of TKIs.

    Pediatric oncology patients can present with various skin lesions related to both primary disease and immunosuppressive treatments. This study aimed to evaluate the cutaneous side effects of chemotherapy in pediatric oncology patients. Sixty-five pediatric oncology patients who were scheduled to undergo chemotherapy from May 2011 to May 2013 were included in the study. Three patients were excluded from the results, as 2 patients died during treatment and 1 patient withdrew from the study; therefore, a total of 62 patients were evaluated for mucocutaneous findings. Patients were grouped according to their oncological diagnoses and a statistical analysis was performed. There was no statistical significance in the incidence of cutaneous side effects of chemotherapy among the different diagnostic groups. Awareness among dermatologists of the possible cutaneous side effects of chemotherapy in pediatric patients and their causes can promote early diagnosis and treatment in this patient population.

    A series of previously neglected sexually related side effects to radical prostatectomy (RP) has been identified over the recent years. These include orgasm-associated incontinence (OAI), urinary incontinence in relation to sexual stimulation (UISS), altered perception of orgasm, orgasm-associated pain (OAP), penile shortening (PS), and penile deformity. The aim of this article is to conduct a systematic review of the literature regarding the above-mentioned side effects. A predefined search strategy was applied in a thorough search of Medline, Web of science, and the online Cochrane library. The PRISMA guidelines for systematic reviews were followed, and protocol as well as search strategies was registered at http://www.crd.york.ac.uk/Prospero/ (RN: CRD42012003165). The main outcome measure was incidence rates for the relevant side effects. A total of 43 articles were included. OAI and UISS are experienced by 20-93% of RP patients at least a few times after surgery. Although these issues are associated to postoperative daytime incontinence, previous transurethral resection of the prostate (TURP) is the only known predicting factor. Alterations of orgasmic function are experienced by approximately 80% after RP. Erectile dysfunction seems to play an important role in waning orgasmic function. OAP is only experienced by a subset of the patients with reported rates varying between 3% and 19%. Sparing of the tips of the seminal vesicles has been shown to double the risk of OAP. PS occurs in 15-68% of RP patients. Nerve sparing and preservation of erectile function may help preserve penile length. With regard to all side effects, studies indicate that they are reduced over time. The sexually related side effects summarized in this review are common after RP. Meanwhile, it is difficult to predict which patients are at risk. Daytime incontinence, previous TURP, a lack of nerve sparing, and erectile dysfunction are all associated with the above-mentioned sexually related

    Full Text Available Active immunization of children has been proven very effective in elimination of life threatening complications of many infectious diseases in developed countries. However, as vaccination-preventable infectious diseases and their complications have become rare, the interest focuses on immunization-related adverse reactions. Unfortunately, fear of vaccination-related adverse effects can led to decreased vaccination coverage and subsequent epidemics of infectious diseases. This review includes reports about possible side effects following vaccinations in children with neurological disorders and also published recommendations about vaccinating children with neurological disorders. From all international published data anyone can conclude that vaccines are safer than ever before, but the challenge remains to convey this message to society.

    Mood disorder and depressive syndromes represent a common comorbid condition in neurological disorders with a prevalence rate that ranges between 20% and 50% of patients with stroke, epilepsy, multiple sclerosis, and Parkinson's disease. Notwithstanding, these conditions are often under-diagnosed and under-treated in the clinical practice and negatively affect the functional recovery, the adherence to treatment, the quality of life, and even the mortality risk. In addition, a bidirectional association between depression and neurological disorders may be possible being that depressive syndromes may be considered as a risk factor for certain neurological diseases. Despite the large amount of evidence regarding the effects of music therapy (MT) and other musical interventions on different aspects of neurological disorders, no updated article reviewing outcomes such as mood, emotions, depression, activity of daily living and so on is actually available; for this reason, little is known about the effectiveness of music and MT on these important outcomes in neurological patients. The aim of this article is to provide a narrative review of the current literature on musical interventions and their effects on mood and depression in patients with neurological disorders. Searching on PubMed and PsycInfo databases, 25 studies corresponding to the inclusion criteria have been selected; 11 of them assess the effects of music or MT in Dementia, 9 explore the efficacy on patients with Stroke, and 5 regard other neurological diseases like Multiple Sclerosis, Amyotrophic Lateral Sclerosis/motor neuron disease, Chronic quadriplegia, Parkinson's Disease, and Acquired Brain dysfunctions. Selected studies are based on relational and rehabilitative music therapy approaches or concern music listening interventions. Most of the studies support the efficacy of MT and other musical interventions on mood, depressive syndromes, and quality of life on neurological patients.

    Desmopressin is frequently used in patients with bleeding disorders because of its prohaemostatic effects. In recent years desmopressin use increased due to reported high incidence of inhibitors in mild haemophilia after clotting factor infusion and the rising costs of clotting factor concentrates. The safety and frequency of side effects have hardly been assessed in well-designed studies. We therefore prospectively evaluated side effects of desmopressin in a large unselected cohort of bleeding disorder patients, who received a desmopressin test dose. Blood was drawn prior to, one, three, six and 24 h after desmopressin. Primary outcome was change in serum sodium, haematocrit, serum- and urine osmolality, body weight and vital signs. Self-reported side effects were evaluated as secondary outcome. In total, 108 patients were included, median age 30 years, the majority of whom had von Willebrand disease type 1 (76%). A significant change in water balance parameters was observed. Four patients (4%) had hyponatraemia (≤135 mmol L(-1) ) after 24 h but no severe hyponatraemia occurred (≤125 mmol L(-1) ). After infusion, 41 (38%) patients were hypotensive (≤90 mmHg SBP and/or ≤60 mmHg DBP) and 10 (9%) presented with tachycardia (>100 min(-1) ). However, none of these effects sustained at 24 h. Infusion was discontinued in one patient because of tachycardia, nausea and malaise. Self-reported side effects included: headache, fatigue, flush and dizziness. Observed side effects correspond with the known antidiuretic and vasomotor effects of desmopressin. Changes in parameters were temporary and not clinically relevant. In conclusion, our study supports desmopressin use as a safe treatment option in patients with various bleeding disorders. © 2015 John Wiley & Sons Ltd.

    Side effects of self-treatment of eight obese women aged between 28 and 45 (average 36.5) with the body mass index (BMI) between 28 and 32 (average 30) kg/m2 have been described. All these women, without any medical consultation and upon their own will had been using Meizitanc as the only remedy for slimming. They started with a dosage of 1 capsule per day, gradually increasing the Meizitanc dose to 3 capsules a day. The patients had used the drug from 2.5 to 6 (average 3.2) months. There were many side effects observed in all women like palpitation, headache and vertigo, warm feeling, nervousness, and tremor of the hands which was observed in four patients. All these effects appeared during the last few weeks and thus forced them to get the consultation in the Poison Information Centre in the Medical University of Gdańsk. All capsules were examined with the use of gas chromatography and mass spectrophotometer GC/MS. It was found that each capsule contained 10 mg of sibutramine. There was no information about the presence of sibutramine in the composition of Meizitanc on the package and leaflet. After discontinuation of Meizitanc all side effects disappeared. Special caution is advised during the Meizitanc treatment. In case of any side effects like palpitation, headache and vertigo, nervousness or tremor which take place during the Meizitanc treatment the medical consultation is needed.

  13. Effect of protein crystal hydration on side chain conformational heterogeneity

    Science.gov (United States)

    Atakisi, Hakan; Moreau, David; Hopkins, Jesse; Thorne, Robert; Robert Thorne's Group Team

    The structure of protein crystals is determined in part by water-mediated interactions involving both protein surface-ordered (hydration) and bulk water, and so is sensitive to the relative humidity of the environment. Monoclinic lysozyme provides a remarkable model for studying structural changes induced by dehydration, as it maintains excellent order for relative humidities (r.h.) down to 5%, corresponding to solvent content of 9% by volume, much smaller than the 88% (22% by volume) at which lysozyme loses its enzymatic activity. Although the main chain conformation does not change significantly, the effect of dehydration on side chain conformations has not been systematically studied. High resolution (1.1 to 1.7 A) structural data sets for monoclinic lysozyme at r.h. between 99% and 11% have been analyzed to identify major and minor side chain conformers at each humidity, and to map out how the side chain conformational ensemble evolves with hydration. Modest dehydration produces comparable overall effects to cooling to T =100 K, but with conformational changes largely confined to solvent-exposed residues. The largest side chain conformation changes occur at humidities that deplete water within the first two hydration shells.

  14. Supply-side and demand-side cost sharing in deregulated social health insurance: which is more effective?

    Science.gov (United States)

    Trottmann, Maria; Zweifel, Peter; Beck, Konstantin

    2012-01-01

    Microeconomic theory predicts that if patients are fully insured and providers are paid fee-for-service, utilization of medical services exceeds the efficient level ('moral hazard effect'). In Switzerland, both demand-side and supply-side cost sharing have been introduced to mitigate this problem. Analyzing a panel dataset of about 160,000 adults, we find both types of cost sharing to be effective in curtailing the use of medical services. However, when moral hazard mitigation is traded off against risk selection, the minimum-deductible, supply-side cost sharing option ranks first, followed by the medium-deductible demand-side alternative, making the supply-side option somewhat more effective.

    Full Text Available Glucocorticoids have been used in clinical medicine since 1940s. Despite the time-long use they are still a subject of active ongoing research. We describe the mode of action, pharmacology and side effects to enable proper prescription of these drugs. Glucocorticoids exert genomic and non-genomic effects, the latter become important at higher doses. The nomenclature of dosage ranges and the principles of dosage adjustments are given. Glucocortioid use is associated with frequent and important side effects in numerous organ systems. Prophylactic treatments for osteoporosis and infections are described. The suppression of hypothalamic-hypophyseal hormonal axis determines the need for gradual glucocorticoid withdrawal and supplementation after discontinuation. Finally, glucocorticoid withdrawal syndrome is described.

    Full Text Available Introduction. Vemurafenib is a selective inhibitor of serine-threonine kinase BRAF used in the treatment of advanced melanoma with BRAF mutation. Effectiveness of this drug was confirmed in a large clinical trial, which led to the increase of its usage. During treatment with vemurafenib, particular attention should be paid to the numerous side effects, including those concerning the skin. Vemurafenib is highly toxic to the skin. Skin lesions occurring during the treatment of melanoma with this medicament can be divided into: early (observed 3 to 6 weeks after beginning treatment, late (observed 6 weeks after beginning treatment and hypersensitivity reactions to vemurafenib. Objective. Presentation of vemurafenib toxic effects on the skin and side effects that can be caused by this drug. Case report. We present a 58-year-old woman with metastatic melanoma who was treated with vemurafenib. During the course of therapy, numerous adverse reactions, including inflammatory tumors, emergence of a number of melanocytic naevi, skin horns, alopecia, hyperkeratosis of the palms and soles, and palmar erythrodysesthesia were observed. She was treated with anti-inflammatory drugs, an antibiotic, circulation-improving preparations and local moisturizing and keratolytic treatment. The patient remains under the care of oncologists and dermatologists. Conclusions. The new generation anti-cancer drugs bring hope for a cure or prolongation of life, but can also significantly reduce the quality of life by inducing both general and local adverse side effects. Oncological patients should also be taken care of by dermatologists.

    2017-12-01

    An old anesthetic agent, ketamine is finding new use in lower doses for analgesic purposes. There are concerns stemming from its potential side effects-specifically psychomimetic effects. These side effects are directly related to dose amount. The doses used for analgesic purposes are much lower than those used for anesthesia purposes. A literature review was performed to ascertain potential side effects and/or adverse events when using ketamine for analgesia purposes. The search included CINAHL, PubMed, and Ovid using the search terms "ketamine," "ketamine infusion," "pain," "adverse events," "practice guideline," and "randomized controlled trial." Searches were limited to full-text, peer-reviewed articles and systematic reviews. Initially 1,068 articles were retrieved. The search was then narrowed by using the Boolean connector AND with various search term combinations. After adjusting for duplication, article titles and abstracts were reviewed, leaving 25 articles for an in-depth analysis. Specific exclusion criteria were then applied. The literature supports the use of ketamine for analgesic purposes, and ketamine offers a nonopioid option for the management of some pain conditions. Because ketamine is still classified as an anesthetic agent, health care institutions should develop their own set of policies and protocols for the administration of ketamine. By using forethought and understanding of the properties of ketamine, appropriate care may be planned to mitigate potential side effects and adverse events so that patients are appropriately cared for and their pain effectively managed.

FONTES DE DADOS: Revisão de literatura nos últimos doze anos através de pesquisa no Medline e Lilacs. RESULTADOS: Dentre os efeitos colaterais que surgem em curto prazo, prevalecem a redução de apetite, insônia, cefaléia e dor abdominal, sendo a maioria autolimitada, dose-dependente e de média intensidade. Dentre aqueles em longo prazo, são descritas alterações discretas de pressão arterial e freqüência cardíaca e uma possível discreta diminuição da estatura. O abuso e a dependência ao medicamento são observados muito raramente. CONCLUSÕES: O perfil de efeitos colaterais do metilfenidato é seguro, não parecendo justificar o seu uso constrito no Brasil, ante os benefícios robustos amplamente demonstrados na literatura.OBJECTIVE: To review main short-term and long-term side effects of methylphenidate in the treatment of Attention-Deficit Disorder in children. SOURCE OF DATA: a 12-year review in Medline and Lilacs. RESULTS: Among those side effects showed in the short-term, anorexia, insomnia, headache and abdominal pain are the most common ones, being the majority self-limited, dose-dependent and of medium intensity. Long-term side effects consist of mild blood pressure and heart rate increase and possible light growth suppression effect. Abuse and dependency are very rare. CONCLUSIONS: Methylphenidate side effects profile is safe and does not seem to justify its restricted use in Brazil, considering its solid benefits widely demonstrated in literature.

    EEG interpretation is a fundamental procedural skill in the practice of neurology, but there is no standardized method for educating residents. One-to-one instruction is commonly employed, but is time intensive for supervising physicians, provides arbitrary exposure to normal and abnormal EEG patterns, and often lacks immediate and detailed feedback on performance. Here, we investigated the effectiveness of a novel automated program to assist in educating neurology residents in EEG interpretation. An EEG teaching program was developed to provide neurology residents EEG training less dependent on attending supervision. Residents enter interpretations of full-length pre-selected EEGs and receive immediate feedback based on consensus interpretation of supervising epileptologists. Resident learning was assessed based on performance on matched pre- and post-tests covering common EEG findings including artifacts, normal variants, and abnormalities. Twenty residents were included in this analysis: 12 post-graduate year (PGY) 3 and eight PGY 4 neurology residents. All residents showed improvement, from a mean score of 42.7% (95% CI 36.9-48.5%) on the pre-test to 75.4% (95% CI 70.7-80.2%) on the post-test (pteaching module spread over a 3-week rotation. This pilot study demonstrated the effectiveness of an automated EEG teaching program used by neurology residents in training. This tool could serve as an effective method of supplementing resident education. Copyright © 2016 British Epilepsy Association. All rights reserved.

    Beakley, Burton D; Kaye, Adam M; Kaye, Alan D

    2015-01-01

    Serotonin syndrome is a mild to potentially life-threatening syndrome associated with excessive serotonergic activity within the central nervous system. Serotonin syndrome is associated with medication use, drug interactions, and overdose. While serotonin syndrome is often associated with the use of selective serotonin inhibitors (SSRI), an increasing number of reports are being presented involving the use of tramadol. This review article contains an overview of serotonin syndrome while specifically looking at tramadol's pharmacology and risk factors for serotonin syndrome. With tramadol's increasing popularity, the goal of this article is to make physicians more alert and aware of this potential side effect associated with tramadol. In conclusion, with the increasing incidence of serotonin syndrome, prescribing physicians should be aware of and educate their patients on the potential side effects of tramadol. It is important that the prescribing physician reviews patient medications for concurrent serotonergic drugs and monitors for potential abuse.

    We review Side Effects, a 2013 film involving bioethics, pharmaceuticals, and financial conspiracies. After the main character Emily unsuccessfully attempts suicide, she begins receiving care from a psychiatrist, Dr. Banks. Following numerous events, she is placed on a fictional antidepressant, Ablixa, which leads her to suffer from sleepwalking. During an episode of sleepwalking she commits a serious crime. The film poses an interesting dilemma: How responsible would the physician be in this instance? We analyze this question by applying numerous ethical principles.

    Although combined oral contraceptive pills (COCPs) are one of the most commonly used methods of contraception in western countries, they are taken by only a minority of sexually active women in Turkey. The purpose of this research has been to define women's specific misconceptions with regard to the side effects of COCPs. This descriptive and cross-sectional research was conducted on 418 reproductive aged women who agreed to participate. Data were collected through face-to-face interviews with a questionnaire which assessed socio-demographic characteristics and women's beliefs about the side effects of COCPs. It is observed that 45.2% believed that the pills cause weight gain. Another 7.9% of the cases held the belief that COCPs cause cancer. A group of 13.4% of the subjects thought that COCPs lead to infertility, 28.7% believed that they cause headache, 41.1% believed that they cause acne and/or an increase in body hair, and 11.7% were afraid that they cause a decrease in libido. The present study has shown that misconceptions about the side effects of COCPs were considerably prevalent among this cohort group of Turkish women. Healthcare professionals have the potential of playing an important role in dispersing these misconceptions.

  9. An Audit of the Effectiveness of Large Group Neurology Tutorials for Irish Undergraduate Medical Students

    2016-07-01

    The aim of this audit was to determine the effectiveness of large group tutorials for teaching neurology to medical students. Students were asked to complete a questionnaire rating their confidence on a ten point Likert scale in a number of domains in the undergraduate education guidelines from the Association of British Neurologists (ABN). We then arranged a series of interactive large group tutorials for the class and repeated the questionnaire one month after teaching. In the three core domains of neurological: history taking, examination and differential diagnosis, none of the students rated their confidence as nine or ten out of ten prior to teaching. This increased to 6% for history taking, 12 % in examination and 25% for differential diagnosis after eight weeks of tutorials. This audit demonstrates that in our centre, large group tutorials were an effective means of teaching, as measured by the ABN guidelines in undergraduate neurology.

    We have investigated the neuroexcitatory and neurodegenerative effects of brevetoxin on neonatal rats. Brevetoxin, a marine-biotoxin that has been implicated in several seafood poisoning incidents, is produced by the dinoflagellate Gymnodinium brevis. Four studies were done: dose response, northern analysis, immunohistochemistry and neurodegeneration. We found that neonatal rats are much more sensitive to brevetoxin than adult rats. The effectiveness of c-fos as a biomarker is being investigated, because of the high basal expression in young animals. The neurodegeneration, although not available yet, should provide valuable information.

  11. Neurological Effects of Honey: Current and Future Prospects

    2014-01-01

    Full Text Available Honey is the only insect-derived natural product with therapeutic, traditional, spiritual, nutritional, cosmetic, and industrial value. In addition to having excellent nutritional value, honey is a good source of physiologically active natural compounds, such as polyphenols. Unfortunately, there are very few current research projects investigating the nootropic and neuropharmacological effects of honey, and these are still in their early stages. Raw honey possesses nootropic effects, such as memory-enhancing effects, as well as neuropharmacological activities, such as anxiolytic, antinociceptive, anticonvulsant, and antidepressant activities. Research suggests that the polyphenol constituents of honey can quench biological reactive oxygen species and counter oxidative stress while restoring the cellular antioxidant defense system. Honey polyphenols are also directly involved in apoptotic activities while attenuating microglia-induced neuroinflammation. Honey polyphenols are useful in improving memory deficits and can act at the molecular level. Therefore, the ultimate biochemical impact of honey on specific neurodegenerative diseases, apoptosis, necrosis, neuroinflammation, synaptic plasticity, and behavior-modulating neural circuitry should be evaluated with appropriate mechanistic approaches using biochemical and molecular tools.

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

    Directory of Open Access Journals (Sweden)

    Anita Piasek

    2009-04-01

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

  15. Can melatonin prevent or improve metabolic side effects during antipsychotic treatments?

    In the last two decades, second-generation antipsychotics (SGAs) were more frequently used than typical antipsychotics for treating both psychotic and nonpsychotic psychiatric disorders in both children and adolescents, because of their lower risk of adverse neurological effects, that is, extrapyramidal symptoms. Recent studies have pointed out their effect on weight gain and increased visceral adiposity as they induce metabolic syndrome. Patients receiving SGAs often need to be treated with other substances to counteract metabolic side effects. In this paper, we point out the possible protective effect of add-on melatonin treatment in preventing, mitigating, or even reversing SGAs metabolic effects, improving quality of life and providing safer long-term treatments in pediatric patients. Melatonin is an endogenous indolamine secreted during darkness by the pineal gland; it plays a key role in regulating the circadian rhythm, generated by the suprachiasmatic nuclei (SCN) of the hypothalamus, and has many other biological functions, including chronobiotic, antioxidant and neuroprotective properties, anti-inflammatory and free radical scavenging effects, and diminishing oxidative injury and fat distribution. It has been hypothesized that SGAs cause adverse metabolic effects that may be restored by nightly administration of melatonin because of its influence on autonomic and hormonal outputs. Interestingly, atypical anti-psychotics (AAPs) can cause several sleep disorders, and circadian misalignment can influence hormones involved in the metabolic regulation, such as insulin, leptin, and ghrelin; furthermore, a relationship between obesity and sleep curtailment has been demonstrated, as well as sleep deprivation in rats has been associated with hyperphagia. Metabolic effects of melatonin, both central and peripheral, direct and indirect, target most metabolic disorders reported during and after SGA treatment in children, adolescents, and adults.

    A case of severe metoclopramide-induced akathisia in a breast cancer patient being treated with chemotherapy is presented, eventually culminating in hospital admission. In retrospect, this adverse effect was not recognized for several weeks because the prescription had not been properly recorded in the chart, the patient initially denied using the drug, and extensive psychological adjustment difficulties were also present. Movement disorders as an adverse effect of metoclopramide have been described on a regular basis over the past decades. Case reports such as this confirm there is under-recognition of adverse effects and emphasize the need to take a comprehensive medication history and recognize well known side effects of medications such as metoclopramide.

    2017-11-01

    Full Text Available The core of the digital transition is the representation of all kinds of real-world entities and processes and an increasing number of cognitive processes by digital information and algorithms on computers. These allow for seemingly unlimited storage, operation, retrieval, and transmission capacities that make digital tools economically available for all domains of society and empower human action, particularly combined with real-world interfaces such as displays, robots, sensors, 3D printers, etc. Digital technologies are general-purpose technologies providing unprecedented potential benefits for sustainability. However, they will bring about a multitude of potential unintended side effects, and this demands a transdisciplinary discussion on unwanted societal changes as well as a shift in science from analog to digital modeling and structure. Although social discourse has begun, the topical scope and regional coverage have been limited. Here, we report on an expert roundtable on digital transition held in February 2017 in Tokyo, Japan. Drawing on a variety of disciplinary backgrounds, our discussions highlight the importance of cultural contexts and the need to bridge local and global conversations. Although Japanese experts did mention side effects, their focus was on how to ensure that AI and robots could coexist with humans. Such a perspective is not well appreciated everywhere outside Japan. Stakeholder dialogues have already begun in Japan, but greater efforts are needed to engage a broader collection of experts in addition to stakeholders to broaden the social debate.

    2008-01-01

    Results achieved in treating the Parkinson's disease (PD) by the dopamine receptor agonist, ropinirole, have been hampered by its side effects. According to the MEDLINE, the most common side effects of ropinirole are extreme sleepiness and/or sudden sleep attacks, nausea, dyspepsia, vertigo, orthostatic hypotension and leg oedema. The prospective research included PD patients who were administered non-ergoline dopamine agonist, ropinirole, over this period of time. The control group of patients were treated with levodopa. The research included 50 patients: 31 women and 19 men, of the mean age of 61.4 +/- 4.3 years. One patient reported sleepiness and one of them sudden sleep attacks. Nausea was experienced by three patients, and vertigo by two. Depression, orthostatic hypotension, leg oedema, dyspepsia, dry cough and hypersalivation were registered in particular cases. The control group of PD patients, treated with levodopa, comprised 52 patients, 33 women and 19 men of the mean age of 63.2 +/- 4.1 years. In the control group, nausea was registered in two patients. The non-ergoline dopamine agonist, ropinirole, most commonly causes nausea and sleepiness, less commonly uncontrollable sleep attacks, vertigo, dyspepsia, orthostatic hypotension, leg oedema. Dry cough and hypersalivation are recorded sporadically (Tab. 1, Ref. 22).

  19. Local Side Effects of Sublingual and Oral Immunotherapy.

    Passalacqua, Giovanni; Nowak-Węgrzyn, Anna; Canonica, Giorgio Walter

    Sublingual immunotherapy (SLIT) is increasingly used worldwide, and several products have been recently registered as drugs for respiratory allergy by the European Medicine Agency and the Food and Drug Administration. Concerning inhalant allergens, the safety of SLIT is overall superior to that of subcutaneous immunotherapy in terms of systemic adverse events. No fatality has been ever reported, and episodes of anaphylaxis were described only exceptionally. Looking at the historical and recent trials, most (>90%) adverse events are "local" and confined to the site of administration. For this reason, a specific grading system has been developed by the World Allergy Organization to classify and describe local adverse events. There is an increasing amount of literature concerning oral desensitization for food allergens, referred to as oral immunotherapy. Also, in this case, local side effects are predominant, although systemic adverse events are more frequent than with inhalant allergens. We review herein the description of local side effects due to SLIT, with a special focus on large trials having a declared sample size calculation. The use of the Medical Dictionary for Regulatory Activities nomenclature for adverse events is mentioned in this context, as recommended by regulatory agencies. It is expected that a uniform classification/grading of local adverse events will improve and harmonize the surveillance and reporting on the safety of SLIT.

All patients had symptoms consistent with pronounced autonomic dysfunction including different degrees of orthostatic intolerance, severe non-migraine-like headache, excessive fatigue, cognitive dysfunction, gastrointestinal discomfort and widespread pain of a neuropathic character. We found consistency in the reported symptoms as well as between our findings and those described by others. Our findings neither confirm nor dismiss a causal link to the Q-HPV vaccine, but they suggest that further research is urgently warranted to clarify the pathophysiology behind the symptoms experienced in these patients and to evaluate the possibility and the nature of any causal link and hopefully establish targeted treatment options. not relevant. not relevant.

    This study aimed at investigating serious side effects of the pupillary dilation protocol used in Caen University Hospital for the screening of retinopathy of prematurity. This protocol includes one drop of phenylephrine 5% and two drops of tropicamide 0.5% instilled at a 5-minute interval. This retrospective study included all premature infants with a birth weight less than or equal to 1500 g and/or a gestational age less than or equal to 30 gestational weeks, hospitalized in the neonatal intensive care unit of Caen University Medical Center, having ocular fundus examinations for retinopathy of prematurity screening between 2009 and 2014. The medical records of patients who died or developed necrotizing enterocolitis were reviewed to analyze the imputability of the two eye drops used for pupil dilation. Five-hundred and twelve infants were included, corresponding to 1033 ocular fundus examinations. No case of death could be ascribed to the use of eye drops. Two cases of necrotizing enterocolitis could be ascribed to the use of tropicamide with a doubtful and plausible intrinsic imputability according to French imputability criteria. The pupillary dilation protocol used in Caen University Hospital for screening of retinopathy of prematurity might be implicated in two cases of necrotizing enterocolitis with an uncertain imputability of tropicamide 0.5% eye drops. No serious side effect could be ascribed to the use of phenylephrine 5% eye drops in this study. Copyright © 2015 Elsevier Masson SAS. All rights reserved.

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

    Antidepressant therapy aims to reach remission of depressive symptoms while reducing the complications and risks of relapse. Even though they have proven their efficacy, it takes several weeks for antidepressants to demonstrate full effectiveness, and adverse effects occur more quickly or (quicker) which can be a source of poor compliance. This latest aspect often leads to dose reduction and/or change of molecule that have the effect of delaying remission. This review attempts to present, from the pharmacological properties of the major classes of antidepressants (monoamine oxidase inhibitor [MAOI], tricyclic antidepressants [TCA], selective serotonin reuptake inhibitor [SSRI] and serotonin and noradrenaline reuptake inhibitor [SNRI]), to the pharmacological mechanisms involved in adverse effects by focusing on sexual dysfunction, nausea/vomiting, and weight changes and sleep disruption. If the activation of dopamine D 1/2  or norepinephrine receptors through the autonomic nervous system controls and facilitates sexual desire, increasing serotoninergic transmission through 5-HT 1B/2A/2C receptors activation inhibits this process. The pharmacological properties of drugs inducing nausea/vomiting activate opiate receptors μ, increase dopaminergic and serotoninergic transmission activating the dopamine D 2  and serotonin 5-HT 3  receptors, respectively. Among the causes responsible for weight gain under antidepressant therapy, monoamine neurotransmission still plays an important role. The blockade of serotonin 5-HT 2C or histamine H 1  receptors is directly responsible for weight gain. Finally, the activation of 5-HT 1A/1B/3/7 serotoninergique receptors modulates wakefulness, raid eyes movement or sleep duration. In conclusion, if antidepressant activity of SERT or MAO inhibitors is an indirect consequence of postsynaptic 5-HT, DA, NA receptor activation, it is also responsible for side effects, causes of poor compliance and hence therapeutic failures. Finally, we

    Labetalol is often used in severe preeclampsia (PE). Hypotension, bradycardia and hypoglycemia are feared neonatal side effects, but may also occur in (preterm) infants regardless of labetalol exposure. We analyzed the possible association between intrauterine labetalol exposure and such side effects. From 1 January 2003 through 31 March 2008, all infants from mothers suffering severe PE admitted to one tertiary care center were included. Severe PE was defined according to the International Society for the Study of Hypertension in Pregnancy (ISSHP) criteria. Infants exposed to labetalol in utero (labetalol infants) were compared with infants, who were not exposed to labetalol (controls). Neonatal records were reviewed for hypotension (RRlabetalol, whereas 54 were not (controls). Gestational age at delivery and birthweight were similar in both groups (31.8 vs. 32.8 weeks (p=0.06) and 1510 vs. 1639 grams (p=0.25), respectively for the labetalol vs. control group). Hypotension occurred significantly more in conjunction with labetalol exposure (16, (29.1%) vs. 4 (7.4%); p=0.003), irrespective of the route of administration. Patent ductus arteriosus (PDA) was present in 9 (56%) of hypotensive labetalol infants compared to 1 (24%) infant in the hypotensive control group (NS). In a multivariate regression model, labetalol exposure, the need for intubation and PDA appeared independently associated with hypotension (Plabetalol infants and in 23 (42.6%) of control infants (p=0.62). Bradycardia occurred in 4 (7.3%) of labetalol infants and in 1 (1.9%) of control infants (p=0.18). Hypoglycemia was more common in premature infants (n=45 (48,9%) vs. n=4 (23.5%), p=0.05) in both labetalol and control infants. Hypotension is more common after maternal labetalol exposure, regardless of the dosage and route of administration. The need for intubation and the presence of a PDA also play a role. Hypoglycemia is a very common finding in this population and is merely related to

    Malaria is a leading cause of ill health and neuro-disability in children in sub-Saharan Africa. Impaired cognition is a common outcome of malaria with neurological involvement. There is also a possibility that academic achievement may be affected by malaria with neurological involvement given the association between cognitive ability and academic achievement. This study investigated the effect of malaria with neurological involvement on cognitive ability, behaviour and academic achievement. This prospective case-control study was carried out in Kampala City, Uganda between February 2008 and October 2010. Sixty-two children with a history of malaria with neurological involvement were followed up and given assessments for cognitive ability (working memory, reasoning, learning, visual spatial skills and attention), behaviour (internalizing and externalizing problems) and academic achievement (arithmetic, spelling and reading) three months after the illness. Sixty-one community controls recruited from the homes or neighbouring families of the cases were also given the same assessments. Tests scores of the two groups were compared using analysis of covariance with age, sex, level of education, nutritional status and quality of the home environment as covariates. This study was approved by the relevant ethical bodies and informed consent sought from the caregivers. Children in the malaria group had more behavioural problems than the community controls for internalizing problems (estimated mean difference = -3.71, 95% confidence interval (CI), = -6.34 to -1.08, p = 0.007). There was marginal evidence of lower attention scores (0.40, CI = -0.05 to 0.86, p = 0.09). However, excluding one child from the analyses who was unable to perform the tests affected the attention scores to borderline significance (0.32, CI, = 0.01 to 0.62, p = 0.05). No significant differences were observed in other cognitive abilities or in academic achievement scores. Malaria with neurological

The mean HADS-D subscale score at baseline in the per-protocol cohort (n=296 was 11.7±3.1 points and the corresponding mean HADS-A score was 12.6±3.2. Significant (P<0.0001 improvements in both scores were recorded during fluvoxamine treatment and later follow-up. Most patients (>85% recorded reductions versus baseline in both indices. In the CGI-based assessment, most evaluated patients (>200 experienced moderate to very substantial clinical improvement, with no or limited side effects. Significant improvements were also recorded in the exploratory outcomes of sleep quality, assessed using the Insomnia Severity Index, and cognitive function, assessed using the Montreal Cognitive Assessment (P<0.0001 vs baseline for both. No death or serious adverse drug reactions were reported during the study. The results of this observational study affirm that fluvoxamine is effective and well tolerated for the treatment of depression in the context of neurological disorders.

    Full Text Available The study is designed to assess the frequency and severity of few dose limiting neurological adverse effects of four different schedules of FOLFOX. Patients with histologically confirmed advanced colorectal carcinoma (CRC were included in the study. Toxicity was graded according to CTC v 2.0. The frequency of grade 3 and 4 adverse effects was comparatively assessed in each treatment arm. The difference in the pattern of toxicity between the treatment schedule was evaluated. The most frequent adverse symptom of neurological adverse effect was grade 1 paresthesia in the patients treated with FOLFOX4 schedule. Grade 4 peripheral neuropathy was reported in few patients of FOLFOX7 treatment arm. Frequency and onset of neurological adverse effects like paresthesia, dizziness, and hypoesthesia were significantly different (, whereas frequency and onset of peripheral neuropathy were highly significant ( in each treatment arm of FOLFOX. Peripheral neuropathy was associated with electrolyte imbalance and diabetes in few patients. Frequency of symptoms, for example, paresthesia, is associated with increased number of recurrent exposure to oxaliplatin (increased number of cycles even at low doses (85 mg/m2, whereas severity of symptoms, for example, peripheral neuropathy, is associated with higher dose (130 mg/m2 after few treatment cycles.

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

    CERN Multimedia

    2004-01-01

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

    We report a case of a 68 year-old-female patient with clinical features of drug-induced lupus erythematosus after five years of treatment with amiodarone. She presented generalized skin rash, arthralgia on upper and lower extremities, associated with difficulty to walk. Remarkable laboratory results revealed a positive antinuclear antibody test and a skin rash biopsy showing a superficial and deep perivascular infiltrate of lymphocytes, histiocytes, and eosinophils. Once the etiology of the patient's symptoms was identified, the culprit drug was removed and she had a complete remission of all signs and symptoms. Early diagnose should be recognized for prompt intervention and avoid further complications associated with this rare side-effect.

PubMed, CINAHL, the Cochrane Library and nursing text books. Although targeted therapies often do not have the same systemic toxicities as chemotherapy, they have their own unique side effects. Optic and otic toxicities are seen with a variety of targeted therapies and, although these are not life-threatening toxicities, they do have the potential to severely impair a patient's quality of life. Baseline optic and otic assessments along with periodic assessments throughout treatment can lead to early recognition of problems with the eyes or ears. Recognition and treatment of these problems will help maintain the patient's quality of life. Copyright © 2014 Elsevier Inc. All rights reserved.

    Fractional resurfacing is a new concept in laser treatment designed to divide radiation into multiple evenly spaced microspots. The aim of our study was to analyze side effects and complications following fractional CO₂ laser therapy. This retrospective study involved the analysis of records of patients treated with ablative fractional CO₂ laser. Pain, type and duration of usual side effects, and immediate complications were analysed. Forty-six treatments were studied. The average duration of erythema was 5.2 (±2) days while that of scabs was 4.1 (±1.9) days. Average pain was 3.3/10 (±2.5) for nine patients premedicated with Emla® and 4.1/10 (±2) for the other 14 non-premedicated patients. Complications were reported for 21.7% of the 46 treatments, as follows: 10.6% facial herpes, some of which occurred despite antiviral prophylaxis (valacyclovir 500 mg/day p.o.), 8.7% inflammatory reactions, including severe facial swelling, and 2.2% acne. All complications resolved quickly. Our study specifically examined the safety of CO₂ fractional lasers and showed an acceptable per interventional pain and simple follow-ups. The frequency of complications was high compared to that described with the Fraxel®, but no severe complications were reported. Given the extent of herpes complications, our study encourages the prescription of valacyclovir prophylaxis 500 mg twice a day for all patients. Patients should also be informed of the high risk of severe inflammatory reaction. Copyright © 2010 Elsevier Masson SAS. All rights reserved.

    Oxacillin and cloxacillin are the most frequently used penicillins for the treatment of severe methicillin-susceptible Staphylococcus aureus infections in intensive care units (ICUs), especially endocarditis. International recommendations do not suggest any adaptation of the dosage in case of renal impairment. We wanted to assess the risk factors for overdosing in ICU and the related observed side effects. All patients with a therapeutic drug monitoring of oxa- or cloxacillin between 2008 and 2014 were included. The target range of trough concentration for total antibiotic activity was considered to be 20-50 mg/L. Data concerning the infection, the given treatment, the renal function, and the attributed side effects of overdosing were collected. A logistic regression model was used to compute the measured trough concentrations. Sixty-two patients were included in this study. We found a median trough plasma concentration of 134.3 mg/L (IQR 65.3-201 mg/L). Ten patients (16.1%) reached the target concentration; all other patients (83.9%) were overdosed. Eleven patients (17.7%) experienced neurological side effects attributed to a high antibiotic concentration, i.e. persistent coma and delirium. When adjusted on the dosage used, the risk of overdosing was significantly associated with a creatinine clearance cloxacillin treatment in case of endocarditis and severe infections occurring in ICU, 83.9% of patients are largely overdosed. Considering the observed side effects, doses should be accurately monitored and reduced, particularly when renal replacement therapy is needed.

    2015-10-01

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

    2016-01-01

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

    The benefits of clinical neurofeedback training are well known, however, its adverse side-effects are less studied. This research focuses on the transient adverse side effects of neurofeedback training via a double-blind, sham/controlled methodology. Thirty healthy undergraduate students volunteers were randomly divided into three treatment groups: increasing a modified Sensory Motor Rhythm, increasing Upper Alpha, and Sham/control group who receive a random reward. The training sessions were administered for a total of ten sessions. Questionnaires of transient adverse side effects were completed by all volunteers before each session. The results suggest that similar to most medical treatments, neurofeedback can cause transient adverse side effects. Moreover, most participants reported experiencing some side effects. The side effects can be divided into non-specific side effect, associated with the neurofeedback training in general and specific ones associated with the particular protocol. Sensory Motor Rhythm protocol seems to be the most sensitive to side effects.

    Side effects of prescribed and nonprescribed psychostimulant use are understudied. The study examined side effects of prescribed and nonprescribed psychostimulant use in a college sample with attention to possible gender differences. 2716 undergraduates (1448 male) between the ages of 17 and 57 years (M = 19.43 years, SD = 1.7 years) completed an online survey that included questions about the subjective side effects of prescribed and nonprescribed psychostimulant use. Results suggested that prescribed users more frequently reported side effects, compared to nonprescribed users. For prescribed users, females more frequently reported appetite, somatic, and anxiety-related side effects compared to males. For nonprescribed users, while females reported more somatic and anxiety-related side effects, males more frequently reported loss of sex drive and sweating as side effects. Conclusions/Importance: These findings suggest prescribed users of psychostimulants more frequently report side effects with prominent gender differences in line with gender roles.

    The aim of this review is to compare studies concerning female sterilization in order to define the most suitable approach and device for each patient considering timing, safety, cost-effectiveness, failure rate, complication rate and patient satisfaction. A systematic literature search was conducted in electronic databases MEDLINE-EMBASE-Sciencedirect and Cochrane Library between 2000 and 2012. All original descriptions, case reports, retrospective and review articles on tubal sterilization methods have been considered. Outcome measures were effectiveness, tolerability, procedure complications and female satisfaction. The ideal female sterilization system should be a simple, safe, highly efficient, easily learned, inexpensive, one-time procedure without negative side-effects. Nowadays, the trans-cervical approach is associated with minimal postoperative pain, allowing short hospitalization and fast resumption of daily activities. Laparoscopic and laparotomic approaches are considered second choices, since, particularly in developing countries, the transcervical hysteroscopic methods will increasingly spread within gynaecological clinical practice. Safety issues, hospital stay, costs and surgeons' experience are important factors in decision-making of the method for female sterilization. Hysteroscopic devices should be preferred when possible. The counselling time remains a fundamental step in choice. The decision concerning method depends on the setting, the surgeon's experience, the country's economical development and the woman's preference.

    Full Text Available Background: Control of balance is a complex motor skill that involves integration of sensory inputs and the planning and execution of flexible movement patterns. Carrying side packs is famous in our society especially shoulder side packs. Most students carry shoulder side packs and they don't care about the way to carry them to be more balanced. The purpose of the study is to investigate the effect of carrying shoulder side pack on dynamic postural stability and to determine the best way of carrying a shoulder side pack either on the dominant side or non-dominant side that doesn’t affect dynamic postural stability in young healthy female. Methods: Sixty female volunteers aged from 18 to 25 years old participated in the study. Biodex balance system was used to measure the dynamic postural stability in three different occasions (without carrying a shoulder side pack, with carrying a shoulder side pack on the dominant side, and on the non-dominant side with a rest period in between. Results: Repeated measure analysis of variance (ANOVA followed by Bonferroni post hoc test were used to compare dynamic posture balance without carrying and during carrying a shoulder side pack on dominant and non-dominant sides. Analysis revealed that overall, anteroposterior and mediolateral stability indexes reduced significantly (P<0.0001 when carrying shoulder side pack on dominant side in comparison with when carrying shoulder side pack on non-dominant side and without carrying bag. Conclusion: It was concluded that carrying a shoulder side pack on the non-dominant side didn't disturb the postural stability when compared to carrying on the dominant side so, we recommend the students to carry shoulder side packs on the non-dominant side.

    Classical opioid analgesics, including morphine, mediate all of their desired and undesired effects by specific activation of the μ-opioid receptor (μ receptor). The use of morphine for treating chronic pain, however, is limited by the development of constipation, respiratory depression, tolerance and dependence. Analgesic effects can also be mediated through other members of the opioid receptor family such as the κ-opioid receptor (κ receptor), δ-opioid receptor (δ receptor) and the nociceptin/orphanin FQ peptide receptor (NOP receptor). Currently, a new generation of opioid analgesics is being developed that can simultaneously bind with high affinity to multiple opioid receptors. With this new action profile, it is hoped that additional analgesic effects and fewer side effects can be achieved. Recent research is mainly focused on the development of bifunctional μ/NOP receptor agonists, which has already led to novel lead structures such as the spiroindole-based cebranopadol and a compound class with a piperidin-4-yl-1,3-dihydroindol-2-one backbone (SR16835/AT-202 and SR14150/AT-200). In addition, the ornivol BU08028 is an analogue of the clinically well-established buprenorphine. Moreover, the morphinan-based nalfurafine exerts its effect with a dominant κ receptor-component and is therefore utilized in the treatment of pruritus. The very potent dihydroetorphine is a true multi-receptor opioid ligand in that it binds to μ, κ and δ receptors. The main focus of this review is to assess the paradigm of opioid ligands targeting multiple receptors with a single chemical entity. We reflect on this rationale by discussing the biological actions of particular multi-opioid receptor ligands, but not on their medicinal chemistry and design. © 2017 The British Pharmacological Society.

    . We propose that epigenetic side-effects of pharmaceuticals may be involved in the etiology of heart disease, cancer, neurological and cognitive disorders, obesity, diabetes, infertility, and sexual dysfunction. It is suggested that a systems biology approach employing microarray analyses of gene expression and methylation patterns can lead to a better understanding of long-term side-effects of drugs, and that in the future, epigenetic assays should be incorporated into the safety assessment of all pharmaceutical drugs. This new approach to pharmacology has been termed "phamacoepigenomics", the impact of which may be equal to or greater than that of pharmacogenetics. We provide here an overview of this potentially major new field in pharmacology and medicine.

    Despite the availability of new oral anticoagulants, vitamin K antagonists (VKA, such as fluindione, acenocoumarol or warfarin) remain currently the goal standard medicines for oral prevention or treatment of thromboembolic disorders. They inhibit the cycle of the vitamin K and its participation in the enzymatic gamma-carboxylation of many proteins. The VKA prevent the activation of the vitamin K-dependent blood clotting factors limiting thus the initiation of the coagulation cascade. But other proteins are vitamin K-dependent and also remain inactive in the presence of VKA. This is the case of matrix Gla-protein (MGP), a protein that plays a major inhibitory role in the development of vascular calcifications. Several experimental and epidemiological results suggest that the use of the VKA could promote the development of vascular calcifications increasing thus the cardiovascular risk. This risk seems to be higher in patients with chronic kidney disease or mellitus diabetes who are more likely to develop vascular calcifications, and may be due to a decrease of the MGP activity. This review aims at summarizing the data currently available making vascular calcifications the probably underestimated side effects of VKA.

    Background Steam inhalation therapy is often recommended in the treatment of a common cold. However, it has no proven benefit and may in fact have serious adverse side effects in terms of burn injuries. Aim To quantify the human and economic costs of steam inhalation therapy in terms of burn injury. Design and setting A prospective database study of all patients admitted to the burn centres (Beverwijk, Groningen, Rotterdam) and the hospital emergency departments in the Netherlands. Method Number and extent of burn injuries as a result of steam inhalation therapy were analysed, as well as an approximation made of the direct costs for their medical treatment. Results Annually, on average three people are admitted to in one of the Dutch burn centres for burns resulting from steam inhalation therapy. Most victims were children, and they needed skin grafting more often than adults. The total direct medical costs for burn centre and emergency department treatment were €115 500 (£93 000), emotional costs are not reflected. Conclusion As steam inhalation therapy has no proven benefit and the number and extent of complications of this therapy in terms of burn injury are significant, especially in children, steam inhalation therapy should be considered a dangerous procedure and not recommended anymore in professional guidelines and patient brochures.

    2018-01-01

    Full Text Available Photodynamic Therapy (PDT is a non-invasive treatment successfully used for neoplastic, inflammatory and infectious skin diseases. One of its strengths is represented by the high safety profile, even in elderly and/or immuno-depressed subjects. PDT, however, may induce early and late onset side effects. Erythema, pain, burns, edema, itching, desquamation, and pustular formation, often in association with each other, are frequently observed in course of exposure to the light source and in the hours/days immediately after the therapy. In particular, pain is a clinically relevant short-term complication that also reduces long-term patient satisfaction. Rare complications are urticaria, contact dermatitis at the site of application of the photosensitizer, and erosive pustular dermatosis. Debated is the relationship between PDT and carcinogenesis: the eruptive appearance of squamous cell carcinoma (SCC in previously treated areas has been correlated to a condition of local and/or systemic immunosuppression or to the selection of PDT-resistant SCC. Here we review the literature, with particular emphasis to the pathogenic hypotheses underlying these observations.

    Temozolomide (TMZ) is an alkylating agent primarily used to treat tumors of the central nervous system. We describe 2 patients with apparent TMZ-induced central diabetes insipidus. Using our institution's Research Patient Database Registry, we identified 3 additional potential cases of TMZ-induced diabetes insipidus among a group of 1545 patients treated with TMZ. A 53-year-old male with an oligoastrocytoma and a 38-year-old male with an oligodendroglioma each developed symptoms of polydipsia and polyuria approximately 2 months after the initiation of TMZ. Laboratory analyses demonstrated hypernatremia and urinary concentrating defects, consistent with the presence of diabetes insipidus, and the patients were successfully treated with desmopressin acetate. Desmopressin acetate was withdrawn after the discontinuation of TMZ, and diabetes insipidus did not recur. Magnetic resonance imaging of the pituitary and hypothalamus was unremarkable apart from the absence of a posterior pituitary bright spot in both of the cases. Anterior pituitary function tests were normal in both cases. Using the Research Patient Database Registry database, we identified the 2 index cases and 3 additional potential cases of diabetes insipidus for an estimated prevalence of 0.3% (5 cases of diabetes insipidus per 1545 patients prescribed TMZ). Central diabetes insipidus is a rare but reversible side effect of treatment with TMZ.

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

    Intravenous (IV) midazolam may be of value as an alternative paediatric dental sedation technique, but there is some apprehension concerning its routine use due to a lack of evidence regarding its safety and side effects. To review all available literature reporting the side effects of IV midazolam in children undergoing dental procedures. Both randomised controlled trials (RCT) and non-randomised studies were reviewed. Reported side effects were categorised as either significant or minor, and the percentage prevalence of significant or minor side effects per episode of treatment was calculated. Five RCTs were included, in which no significant side events were reported; however, minor side effects were recorded (n = 33, 19.5%), with paradoxical reaction being the most common (n = 11, 6.5%). Six non-randomised studies were included, in which no significant side effects were reported; however, minor side effects were reported (n = 118, 16.8%) with paradoxical reaction being the most common (n = 89, 12.7%). Although no significant side effects were recorded, of the minor side effects reported paradoxical reaction was the most common. Due to inconsistency in side effect reporting, the authors suggest the application of a standardised adverse event reporting tool for future studies of sedation in paediatric dentistry. © 2014 BSPD, IAPD and John Wiley & Sons A/S.

    This study was conducted to evaluate new acupuncture protocols for the clinical treatment of cervical spinal cord diseases in 19 dogs. Three treatment options containing Jing-jiaji (cervical jiaji) were developed to treat neck pain, hemiparesis, and tetraparesis depending on the severity. The interval between the neurological disease onset and treatment (duration of signs), time to improvement after treatment, and recovery time were compared in dogs by body weight, age, and dry needle acupuncture (AP) with or without electro-AP (EAP). The duration of signs was longer in dogs weighing greater than 10 kg than in those weighing less than 10 kg (p< 0.05). Improvement and recovery times did not vary by body weight. Additionally, improvement and recovery times did not vary by age. The improvement and recovery times were longer in the AP+EAP group than the AP group (p< 0.05). Acupuncture with Jing-jiaji was effective in cervical spinal cord diseases in different sized dogs and in middle-aged and senior dogs. This report standardized AP treatment containing Jing-jiaji for canine cervical problems and evaluated its effects. The newly standardized AP methodology offers clinical practitioners an effective way to improve the outcomes of cervical neurological diseases in dogs.

    Full Text Available Mammalian target of rapamycin (mTOR is a serine/threonine protein kinase and activation of its signal pathway plays an important role in regulating protein growth and synthesis as well as cell proliferation and survival. In the present study, we examined the contribution of mTOR and its downstream products to brain injuries and neurological deficiencies after cardiac arrest (CA induced-transient global ischemia. CA was induced by asphyxia followed by cardiopulmonary resuscitation (CPR in rats. Our results showed that expression of p-mTOR, mTOR-mediated phosphorylation of 4E-binding protein 4 (4E-BP1 and p70 ribosomal S6 protein kinase 1 (S6K1 pathways were amplified in CA rats compared to their controls. Blocking mTOR using rapamycin attenuated upregulation of pro-inflammatory cytokines (namely IL-1β, IL-6 and TNF-α, and Caspase-3, indicating cell apoptosis and also promoting the levels of vascular endothelial growth factor (VEGF and its subtype receptor VEGFR-2 in the hippocampus. Moreover, the effects of rapamycin were linked to improvement of neurological deficits and increased brain water content observed in CA rats. In conclusion, activation of mTOR signal is engaged in pathophysiological process during CA-induced transient global ischemia and blocking mTOR pathway plays a beneficial role in regulating injured neuronal tissues and neurological deficits via PIC, apoptotic Caspase-3 and VEGF mechanisms. Targeting one or more of these specific mTOR pathways and its downstream signaling molecules may present new opportunities for neural dysfunction and vulnerability related to transient global ischemia.

This study aimed to determine the cerebrolysin impact on the neurological outcomes and cerebral blood flow. Methods: In a randomized, double-blinded, placebo-controlled trial, 46 patients who had acute focal ischemic stroke were randomly assigned into two groups to receive intravenously either 30 mL of cerebrolysin diluted in normal saline daily for 10 days (n=23 or normal saline alone (n=23 adjunct to 100 mg of aspirin daily. All patients were examined using the National Institutes of Health Stroke Scale and transcranial Doppler to measure the mean flow velocity and pulsatility index (PI of their cerebral arteries at baseline as well as on days 30, 60, and 90. Results: The patients’ mean age was 60±9.7 years, and 51.2% of patients were male. The National Institutes of Health Stroke Scale was significantly lower in the cerebrolysin group compared with the placebo group on day 60 (median 10, interquartile range 9–11, P=0.008 and day 90 (median 11, interquartile range 10–13.5, P=0.001. The median of PI in the right middle cerebral artery was significantly lower in the cerebrolysin group compared with the placebo group on days 30, 60, and 90 (P<0.05. One patient in the cerebrolysin group and two patients in the placebo group died before day 30 (4.3% versus 8.7%. Conclusion: Cerebrolysin can be useful to improve the neurological outcomes and the PI of middle cerebral artery in patients with acute focal ischemic stroke.

  20. Computational drug repositioning based on side-effects mined from social media

    2016-02-01

    Full Text Available Drug repositioning methods attempt to identify novel therapeutic indications for marketed drugs. Strategies include the use of side-effects to assign new disease indications, based on the premise that both therapeutic effects and side-effects are measurable physiological changes resulting from drug intervention. Drugs with similar side-effects might share a common mechanism of action linking side-effects with disease treatment, or may serve as a treatment by “rescuing” a disease phenotype on the basis of their side-effects; therefore it may be possible to infer new indications based on the similarity of side-effect profiles. While existing methods leverage side-effect data from clinical studies and drug labels, evidence suggests this information is often incomplete due to under-reporting. Here, we describe a novel computational method that uses side-effect data mined from social media to generate a sparse undirected graphical model using inverse covariance estimation with ℓ1-norm regularization. Results show that known indications are well recovered while current trial indications can also be identified, suggesting that sparse graphical models generated using side-effect data mined from social media may be useful for computational drug repositioning.

    Neurological diseases are defined as an inappropriate function of the peripheral or central nervous system due to impaired electrical impulses throughout the brain and/or nervous system that may present with heterogeneous symptoms according to the parts of the system involved in these pathologic processes. Growing evidence on genetic components of neurological disease have been collected during recent years. Genetic studies have opened the way for understanding the underlying pathology of many neurological disorders. The outcome of current intense research into the genetics of neurological disorders will hopefully be the introduction of new diagnostic tools and the discovery of potential targets for new and more effective medications and preventive measures.

    Full Text Available This study was a two-armed parallel group design aimed at testing real world effectiveness of a music therapy (MT intervention for children with severe neurological disorders. The control group received only the standard neurorestoration program and the experimental group received an additional MT Auditory Attention plus Communication (ACC protocol just before the usual occupational and speech therapy. Multivariate Item Response Theory (MIRT identified a neuropsychological status-latent variable manifested in all children and which exhibited highly significant changes only in the experimental group. Changes in brain plasticity also occurred in the experimental group, as evidenced using a Mismatch Event Related paradigm which revealed significant post intervention positive responses in the latency range between 308 and 400 ms in frontal regions. LORETA EEG source analysis identified prefrontal and midcingulate regions as differentially activated by the MT in the experimental group. Taken together, our results showing improved attention and communication as well as changes in brain plasticity in children with severe neurological impairments, highlight/comfort the importance of MT for the rehabilitation of patients across a wide range of dysfunctions.

    intubation technique was only slightly more difficult than a simple lacrimal probing. The average operating time, excluding the anesthetic procedures, was respectively 5 min (group 2) and 4 min (group 3). COMPLICATIONS DURING SURGERY: There were no anesthetic or general problems observed in the three groups. Epistaxis was also not noted. Fifteen percent (13/90). The 13 complications noted were: two cases of canaliculitis, one intracanalicular migration, eight probes that disappeared, one keratitis, and one case of involuntary removal by the patient. DELETERIOUS SIDE EFFECTS: Tearing with the probe was in place was noted in 21.1% of the cases (19/90). This tearing disappeared as soon as the probe was removed in 50% of these cases (10/19). Overall, the success rate (absence of epiphora, absence of mucous discharge) was 90% (81/90) with an average follow-up period of 19 weeks (Range, 1 day to 60 weeks). Two cases were lost to follow-up at day 1 and day 7. Group 1: 90.9% (20/22 cases; average age: 65 years, with an average follow-up period of 24 weeks). Group 2: 100% (6/6 cases; average age: 3.1 years, with an average follow-up period of 14 weeks). Group 3: 88.3% (53/60 cases excluding the two cases that were lost to follow-up; mean age: 2.3 years, with an average follow-up period of 16 weeks). From a technical perspective, pushed nasolacrimal intubation is much simpler than the traditional pulled types of nasolacrimal intubation. The anesthetic procedure required is the same as that for a late probing procedure, but the functional results are better. The Masterka is an alternative to simple late probing in the treatment of mucosal nasolacrimal stenoses in patients of over 12 months of age. Copyright © 2011 Elsevier Masson SAS.

    This study investigated the effects of a 10-week hippotherapy program on trunk, pelvis, and hip joint positioning during the stance phase of gait. Eleven children (6 boys and 5 girls; 7.9 ± 2.7 years) with neurological disorders and impaired ambulation participated. Joint range of motion data were collected via 3-dimensional computerized gait analysis before and after the program. Paired t tests were performed on kinematic data for each joint. Significant improvements (P ≤ .008) and large effect sizes (ESs) for sagittal plane hip positions at initial contact and toe-off were found. No differences in pelvic or trunk positioning were determined, although sagittal plane pelvic positioning displayed a trend toward improvement with large ESs. Several trunk variables displayed moderate ESs with a trend toward more upright positioning. Improvements in pelvic and hip joint positioning and more normalized vertical trunk position may indicate increased postural control during gait after 10 sessions of hippotherapy.

    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).

    Management of recurrent cervical cancer by reirradiation after radiation treatment remains controversial. In Indonesia, there is currently no data about reirradiation tumor response and side effects. This study aims to assess the tumor response to and side effects of reirradiation, the effect of time interval between first radiation treatment and cancer recurrence on the tumor response and side effects, and the effect of tumor size on tumor response. A cohort retrospective study with no comparison was done with the Radiotherapy Department at Cipto Mangunkusumo General Hospital, Jakarta. Participants were recurrent cervical cancer patients undergoing reirradiation. Data was collected from patients’ medical records and follow-up phone calls. Twenty-two patients participated in this study. Nine patients (40.9%) had complete responses, 10 patients (45.5%) had partial responses, 1 patient (4.5%) had a stable response, and 2 patients (9.1%) had tumor progressions. In general, 15 patients (68.2%) had no to light side effects (grade 0-2 RTOG) and 7 patients (31.8%) had severe side effects (grade 3-4 RTOG). Four patients (18.1%) had severe gastrointestinal acute side effects, 6 patients (27.3%) had severe gastrointestinal late side effects, 2 patients (9.1%) had severe urogenital side effects, and there were no patients had severe urogenital late side effects. There was no significant difference in tumor response between patients with time interval between first radiation treatment and recurrence of 4 cm. Reirradiation can be considered as a modality in recurrent cervical cancer management since good tumor response was achieved and the majority of patients had no to light side effects (grade 0-2 RTOG). This study found no correlation between tumor response, side effects, and time gap between first radiation treatment and recurrence of 4 cm.

    The objective of the study was to compare the psychiatric and behavioral side effect (PBSE) profiles of both older and newer antiepileptic drugs (AEDs) in children and adolescent patients with epilepsy. We used logistic regression analysis to test the correlation between 83 non-AED/patient related potential predictor variables and the rate of PBSE. We then compared for each AED the rate of PBSEs and the rate of PBSEs that led to intolerability (IPBSE) while controlling for non-AED predictors of PBSEs. 922 patients (≤18 years old) were included in our study. PBSEs and IPBSEs occurred in 13.8% and 11.2% of patients, respectively. Overall, a history of psychiatric condition, absence seizures, intractable epilepsy, and frontal lobe epilepsy were significantly associated with increased PBSE rates. Levetiracetam (LEV) had the greatest PBSE rate (16.2%). This was significantly higher compared to other AEDs. LEV was also significantly associated with a high rate of IPBSEs (13.4%) and dose-decrease rates due to IPBSE (6.7%). Zonisamide (ZNS) was associated with significantly higher cessation rate due to IPBSE (9.1%) compared to other AEDs. Patients with a history of psychiatric condition, absence seizures, intractable epilepsy, or frontal lobe epilepsy are more likely to develop PBSE. PBSEs appear to occur more frequently in adolescent and children patients taking LEV compared to other AEDs. LEV-attributed PBSEs are more likely to be associated with intolerability and subsequent decrease in dose. The rate of ZNS-attributed IPBSEs is more likely to be associated with complete cessation of AED. Copyright © 2017 European Paediatric Neurology Society. Published by Elsevier Ltd.

    Full Text Available Object. It is widely accepted that temporal resective surgery represents an efficacious treatment option for patients with epilepsy of temporal origin. The meticulous knowledge of the potential complications, associated with temporal resective procedures, is of paramount importance. In our current study, we attempt to review the pertinent literature for summating the complications of temporal resective procedures for epilepsy. Method. A PubMed search was performed with the following terms: “behavioral,” “cognitive,” “complication,” “deficit,” “disorder,” “epilepsy,” “hemianopia,” “hemianopsia,” “hemorrhage,” “lobectomy,” “medial,” “memory,” “mesial,” “neurobehavioral,” “neurocognitive,” “neuropsychological,” “psychological,” “psychiatric,” “quadranopia,” “quadranopsia,” “resective,” “side effect,” “surgery,” “temporal,” “temporal lobe,” and “visual field.” Results. There were six pediatric, three mixed-population, and eleven adult surgical series examining the incidence rates of procedure-related complications. The reported mortality rates varied between 0% and 3.5%, although the vast majority of the published series reported no mortality. The cumulative morbidity rates ranged between 3.2% and 88%. Conclusions. Temporal resective surgery for epilepsy is a safe treatment modality. The reported morbidity rates demonstrate a wide variation. Accurate detection and frank reporting of any surgical, neurological, cognitive, and/or psychological complications are of paramount importance for maximizing the safety and improving the patients’ overall outcome.

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

    A growing body of evidence has highlighted the sexual side effects of selective serotonin reuptake inhibitor (SSRI) medication. Whilst most of the research has focused on the prevalence and treatment of sexual difficulties, little is known about how patients cope with the SSRI-related sexual side effects. The objective of this study was to explore women's experiences of coping with the sexual side effects of SSRI medication and interpretative phenomenological analysis was employed for an in-depth exploratory study of a sample of 10 women. Four broad themes emerged which are discussed under the following headings: searching, suffering in silence, trying to resolve and accepting what is. The themes provide an insight into the different strategies used by women to cope with the sexual side effects of SSRI medication and highlight the importance of contextualising these difficulties as part of an overall approach to improve the management and treatment of SSRI-related sexual side effects.

    To study the effects of infection on severe stroke patients in the Neurological Intensive Care Unit (NICU) and to find the related risk factors for mortality of severe stroke patients. We conducted a retrospective study including 343 patients with ischemic or hemorrhagic stroke and staying more than 2 patient-days in the NICU at Beijing Chaoyang Hospital from January 2011 to December 2015 to analyze the infection features of patients with severe stroke in the Neurological Intensive Care Unit. The mortality rate, hospital staying time, hospital costs, infection time and different infection sources were analyzed and Logistic analysis was performed to find the related risk factors for mortality of severe stroke patients. All analysis were conducted using SPSS 18.0. The mortality rate, hospital staying time and hospital costs of stroke patients between infected and uninfected patients were higher in infected patients than the uninfected patients, P<0.05, and except for the hospital staying time, mortality rate and hospital costs were both significantly higher in infected patients. Respiratory tract infection was the most common infection type at all time periods, P<0.05. However, urinary tract infection increased at 72 h after stroke compared with the infection within 72 h after stroke. Blood sugar level, mean arterial pressure, scores of APACHE II, history of stoke, history of heart diseases, infections and respiratory tract infection were significantly different in dead patients compared with the alive patients, P<0.05. Logistic multivariate regression analysis showed that except for history of heart diseases, the other six factors were all associated with mortality of stroke patients and were independent risk factors for mortality of stroke patients. Infection can significantly influence the mortality rate, hospital costs of stroke patients and is an independent risk factors for mortality of stroke patients.

    We aimed to compare the views of cancer patients, family caregivers, and oncologists about the disclosure of side effects in respect to their probability of occurrence, severity, and treatment purpose. We also compared attitudes toward potential harm of side effect disclosure, patients' perceived ability to understand the risk of the side effects, and informed decision-making regarding side effects. A national survey was performed with 750 patient-caregiver dyads (75.5% participation rate) recruited by 134 oncologists in 13 cancer centers (93% participation rate). Attitudes toward communication of side effects were assessed in terms of drug purpose, severity of potential complications, and probability of harm. Most patients (82.1-87.0%) and caregivers (75.9-81.5%) thought they should be informed of all possible drug side effects regardless of risk, severity, or drug purpose and wanted these risks to be communicated explicitly. Patients and their caregivers believed that detailed explanations of side effects did not harm patients, and further, they believed that patients could understand risks and make treatment decision based on that information. In contrast, oncologists held less positive attitudes toward providing detailed information about drug side effects, especially if they were not severe and if the drugs were designed for supportive care. Cancer patients and family members had different perspectives and preferences regarding communication of drug side effects from their oncologists. The data from our study can serve as a guide for oncologists in presenting side effects information to their patients, as well as a basis for physician training.

    Metabotropic glutamate (mGlu) receptor ligands are under clinical development for the treatment of CNS disorders with high social and economic burden, such as schizophrenia, major depressive disorder (MDD), and Parkinson's disease (PD), and are promising drug candidates for the treatment of Alzheimer's disease (AD). So far, clinical studies have shown symptomatic effects of mGlu receptor ligands, but it is unknown whether these drugs act as disease modifiers or, at the opposite end, they accelerate disease progression by enhancing neurodegeneration. This is a fundamental issue in the treatment of PD and AD, and is also an emerging theme in the treatment of schizophrenia and MDD, in which neurodegeneration is also present and contribute to disease progression. Moving from in vitro data and preclinical studies, we discuss the potential impact of drugs targeting mGlu2, mGlu3, mGlu4 and mGlu5 receptor ligands on active neurodegeneration associated with AD, PD, schizophrenia, and MDD. We wish to highlight that our final comments on the best drug candidates are not influenced by commercial interests or by previous or ongoing collaborations with drug companies.

    Simultaneous electrophysiological and behavioral studies were performed on juvenile Japanese medaka (Oryzias latipes) exposed to representative neurotoxic organic chemicals at sublethal concentrations. Non-invasive recordings were made of the electrical impulses generated within giant neuronal Mauthner cells, associated interneurons or motoneurons, and musculature, all of which initiate the startle or escape response in fish. Timing in milliseconds between these electrical sequelae was measured for each fish before and at 24 and 48 hours exposure to a chemical. Also noted was the number of startle responses to number of stimuli ratio (R/S). Other groups of medaka were fed to bluegills and consumption times recorded to assess their ability to escape predation. These results were compared to neurophysiological effect levels. Phenol, 2,4-dinitrophenol, chlorpyrifos, fenvalerate, and 1-octanol impaired the ability of medaka to escape predation at all concentrations. Medaka were more susceptible to predation in high concentrations of carbaryl and strychnine, but less susceptible at low concentrations, whereas the reverse was true for endosulfan. The variety of neurological effects detected at these concentrations suggest that different mechanisms may be responsible. Phenol and strychnine affected Mauthner cell to motoneuron transmission, chlorpyrifos and carbaryl showed neuromuscular effects, and R/S was affected by most chemicals. Although a variety of neurotoxic mechanisms were examined, the exposure threshold for significant effects for each specific compound was found to be consistent for both the neurophysiological and behavioral endpoints.

  6. Effects of Moving Side Walls on Confined Granular Packings

    2011-07-01

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

  7. Deficits in neuronal cytochrome P450 activity attenuate opioid analgesia but not opioid side effects.

    Morphine-like analgesics act on µ opioid receptors in the CNS to produce highly effective pain relief, but the same class of receptors also mediates non-therapeutic side effects. The analgesic properties of morphine were recently shown to require the activity of a brain neuronal cytochrome P450 epoxygenase, but the significance of this pathway for opioid side effects is unknown. Here we show that brain P450 activity is not required for three of morphine׳s major side effects (respiratory depression, constipation, and locomotor stimulation). Following systemic or intracerebroventricular administration of morphine, transgenic mice with brain neuron - specific reductions in P450 activity showed highly attenuated analgesic responses as compared with wild-type (control) mice. However, brain P450-deficient mice showed normal morphine-induced side effects (respiratory depression, locomotor stimulation, and inhibition of intestinal motility). Pretreatment of control mice with the P450 inhibitor CC12 similarly reduced the analgesia, but not these side effects of morphine. Because activation of brain µ opioid receptors produces both opioid analgesia and opioid side effects, dissociation of the mechanisms for the therapeutic and therapy-limiting effects of opioids has important consequences for the development of analgesics with reduced side effects and/or limited addiction liability.

  9. Asparaginase treatment side-effects may be due to genes with homopolymeric Asn codons (Review-Hypothesis).

    Banerji, Julian

    2015-09-01

    The present treatment of childhood T-cell leukemias involves the systemic administration of prokaryotic L-asparaginase (ASNase), which depletes plasma Asparagine (Asn) and inhibits protein synthesis. The mechanism of therapeutic action of ASNase is poorly understood, as are the etiologies of the side-effects incurred by treatment. Protein expression from genes bearing Asn homopolymeric coding regions (N-hCR) may be particularly susceptible to Asn level fluctuation. In mammals, N-hCR are rare, short and conserved. In humans, misfunctions of genes encoding N-hCR are associated with a cluster of disorders that mimic ASNase therapy side-effects which include impaired glycemic control, dislipidemia, pancreatitis, compromised vascular integrity, and neurological dysfunction. This paper proposes that dysregulation of Asn homeostasis, potentially even by ASNase produced by the microbiome, may contribute to several clinically important syndromes by altering expression of N-hCR bearing genes. By altering amino acid abundance and modulating ribosome translocation rates at codon repeats, the microbiomic environment may contribute to genome decoding and to shaping the proteome. We suggest that impaired translation at poly Asn codons elevates diabetes risk and severity.

  10. Autoregressive transitional ordinal model to test for treatment effect in neurological trials with complex endpoints

    2016-11-01

    Full Text Available Abstract Background A number of potential therapeutic approaches for neurological disorders have failed to provide convincing evidence of efficacy, prompting pharmaceutical and health companies to discontinue their involvement in drug development. Limitations in the statistical analysis of complex endpoints have very likely had a negative impact on the translational process. Methods We propose a transitional ordinal model with an autoregressive component to overcome previous limitations in the analysis of Upper Extremity Motor Scores, a relevant endpoint in the field of Spinal Cord Injury. Statistical power and clinical interpretation of estimated treatment effects of the proposed model were compared to routinely employed approaches in a large simulation study of two-arm randomized clinical trials. A revisitation of a key historical trial provides further comparison between the different analysis approaches. Results The proposed model outperformed all other approaches in virtually all simulation settings, achieving on average 14 % higher statistical power than the respective second-best performing approach (range: -1 %, +34 %. Only the transitional model allows treatment effect estimates to be interpreted as conditional odds ratios, providing clear interpretation and visualization. Conclusion The proposed model takes into account the complex ordinal nature of the endpoint under investigation and explicitly accounts for relevant prognostic factors such as lesion level and baseline information. Superior statistical power, combined with clear clinical interpretation of estimated treatment effects and widespread availability in commercial software, are strong arguments for clinicians and trial scientists to adopt, and further extend, the proposed approach.

    Our aim was to estimate the cost-effectiveness of transferring patients with intracerebral hemorrhage from centers without specialized neurological intensive care units (neuro-ICUs) to centers with neuro-ICUs. Decision analytic models were developed for the lifetime horizons. Model inputs were derived from the best available data, informed by a variety of previous cost-effectiveness models of stroke. The effect of neuro-ICU care on functional outcomes was modeled in 3 scenarios. A favorable outcomes scenario was modeled based on the best observational data and compared with moderately favorable and least-favorable outcomes scenarios. Health benefits were measured in quality-adjusted life years (QALYs), and costs were estimated from a societal perspective. Costs were combined with QALYs gained to generate incremental cost-effectiveness ratios. One-way sensitivity analysis and Monte Carlo simulations were performed to test robustness of the model assumptions. Transferring patients to centers with neuro-ICUs yielded an incremental cost-effectiveness ratio for the lifetime horizon of $47,431 per QALY, $91,674 per QALY, and $380,358 per QALY for favorable, moderately favorable, and least-favorable scenarios, respectively. Models were robust at a willingness-to-pay threshold of $100,000 per QALY, with 95.5%, 75.0%, and 2.1% of simulations below the threshold for favorable, moderately favorable, and least-favorable scenarios, respectively. Transferring patients with intracerebral hemorrhage to centers with specialized neuro-ICUs is cost-effective if observational estimates of the neuro-ICU-based functional outcome distribution are accurate. If future work confirms these functional outcome distributions, then a strong societal rationale exists to build systems of care designed to transfer intracerebral hemorrhage patients to specialized neuro-ICUs. © 2014 American Heart Association, Inc.

    Repetitive transcranial magnetic stimulation (rTMS) is a treatment option with proved effectiveness especially in drug resist depression. It is used in functional brain mapping before neurosurgery operations and diagnostic of corticospinal tract transmission. Many studies are performed to evaluate rTMS using in treatment of obsessive - compulsive disorder, schizophrenia, autism, strokes, tinnitus, Alzheimer and Parkinson diseases, cranial traumas. Moreover rTMS was used in treatment of multiple sclerosis, migraine, dystonia. Electromagnetical field generated by rTMS penetrate skin of the scalp and infiltrate brain tissues to a depth of 2 cm, cause neurons depolarization and generating motor, cognitive and affective effects. Depending on the stimulation frequency rTMS can stimuli or inhibit brain cortex. rTMS mechanism of action remains elusive. Probably it is connected with enhancement of neurotransmitters, modulation of signals transductions pathways in Central Nervous System, gene transcription and release of neuroprotective substances. Studies with use of animals revealed that rTMS stimulation can generate brain changes similar to those seen after electric shock therapy without provoking seizures. The aim of presenting study was to analyze actual researches evaluating rTMS use in treatment of psychiatric and neurological diseases. © 2016 MEDPRESS.

    To carry out an integral quantitative assessment of the clinical efficacy of parenteral use of cytoflavin in treatment of patients with CNS disorders based on the systemic selection of published controlled clinical trials and their meta-analysis. Twenty-one high evidence-based studies on the efficacy of parenteral use of cytoflavin in different CNS disorders (4314 patients) have been analyzed. Comparisons with basic treatment groups were undertaken to clarify the drug clinical effects adjusted for heterogeneity and variability of response parameters. An analysis of formalized efficacy indicators (increase in the absolute and relative value, odds ratio (OR) etc.) has demonstrated the advantages of cytoflavin. Group combination has increased the statistical power of the meta-analysis. Two models with fixed (Mantel-Haenszel amendment) and random effects were used. All the estimation protocols in different clinical groups of patients with neurologic diseases provided similar results and confirmed the stability of calculated values irrespective of heterogeneity of data arrays. OR of positive outcomes in neuropathologies treated with cytoflavin was 3,02 with χ2 heterogeneity 427,3 and p = 0,000…, I2= 85,7% (82%; 88%).

  17. Neurological complications in chronic kidney disease

    Directory of Open Access Journals (Sweden)

    2016-10-01

    Full Text Available Patients with chronic kidney disease (CKD are frequently afflicted with neurological complications. These complications can potentially affect both the central and peripheral nervous systems. Common neurological complications in CKD include stroke, cognitive dysfunction, encephalopathy, peripheral and autonomic neuropathies. These conditions have significant impact not only on patient morbidity but also on mortality risk through a variety of mechanisms. Understanding the pathophysiological mechanisms of these conditions can provide insights into effective management strategies for neurological complications. This review describes clinical management of neurological complications in CKD with reference to the contributing physiological and pathological derangements. Stroke, cognitive dysfunction and dementia share several pathological mechanisms that may contribute to vascular impairment and neurodegeneration. Cognitive dysfunction and dementia may be differentiated from encephalopathy which has similar contributing factors but presents in an acute and rapidly progressive manner and may be accompanied by tremor and asterixis. Recent evidence suggests that dietary potassium restriction may be a useful preventative measure for peripheral neuropathy. Management of painful neuropathic symptoms can be achieved by pharmacological means with careful dosing and side effect considerations for reduced renal function. Patients with autonomic neuropathy may respond to sildenafil for impotence. Neurological complications often become clinically apparent at end-stage disease, however early detection and management of these conditions in mild CKD may reduce their impact at later stages.

    Full Text Available 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.

    Although drugs are the most powerful therapeutic tools we have for improving the quality of life of the population, their use is not free of adverse effects. Today there are many polymedicated patients, and it is difficult to find the cause of their adverse effects that increase exponentially when more than 4 drugs are combined. There are a large number of drugs that can result in numerous adverse effects in the oral cavity. The most common are xerostomia, altered taste, gingival enlargement and mucositis caused by cancer treatment. We also review other disorders of the salivary glands, oral mucosal changes, pigmentations, halitosis, osteonecrosis, opportunistic infections and bleeding diathesis.

    Energy drinks are increasingly popular among athletes and others. Advertising for these products typically features images conjuring great muscle power and endurance; however, the scientific literature provides sparse evidence for an ergogenic role of energy drinks. Although the composition of energy drinks varies, most contain caffeine; carbohydrates, amino acids, herbs, and vitamins are other typical ingredients. This report analyzes the effects of energy drink ingredients on prolonged submaximal (endurance) exercise as well as on short-term strength and power (neuromuscular performance). It also analyzes the effects of energy drink ingredients on the fluid and electrolyte deficit during prolonged exercise. In several studies, energy drinks have been found to improve endurance performance, although the effects could be attributable to the caffeine and/or carbohydrate content. In contrast, fewer studies find an ergogenic effect of energy drinks on muscle strength and power. The existing data suggest that the caffeine dose given in studies of energy drinks is insufficient to enhance neuromuscular performance. Finally, it is unclear if energy drinks are the optimal vehicle to deliver caffeine when high doses are needed to improve neuromuscular performance. © 2014 International Life Sciences Institute.

    The multiple levels of knowledge related to the neurological system deter many students from pursuing studies on this topic. Thus, in facing complicated and uncertain medical circumstances, nursing students have diffi-culty adjusting and using basic neurological-nursing knowledge and skills. Scenario-based concept-mapping teaching has been shown to promote the integration of complicated data, clarify related concepts, and increase the effectiveness of cognitive learning. To investigate the effect on the neurological-nursing cognition and learning attitude of nursing students of a scenario-based concept-mapping strategy that was integrated into the neurological nursing unit of a medical and surgical nursing course. This quasi-experimental study used experimental and control groups and a pre-test / post-test design. Sopho-more (2nd year) students in a four-year program at a university of science and technology in Taiwan were convenience sampled using cluster randomization that was run under SPSS 17.0. Concept-mapping lessons were used as the intervention for the experimental group. The control group followed traditional lesson plans only. The cognitive learning outcome was measured using the neurological nursing-learning examination. Both concept-mapping and traditional lessons significantly improved post-test neurological nursing learning scores (p learning attitude with regard to the teaching material. Furthermore, a significant number in the experimental group expressed the desire to add more lessons on anatomy, physiology, and pathology. These results indicate that this intervention strategy may help change the widespread fear and refusal of nursing students with regard to neurological lessons and may facilitate interest and positively affect learning in this important subject area. Integrating the concept-mapping strategy and traditional clinical-case lessons into neurological nursing lessons holds the potential to increase post-test scores significantly

    Jitpakdee, Thanaporn; Mandee, Sahatsa

    2014-06-01

    Opioid is the gold standard for treating moderate-to-severe pain in pediatric patients. However, its undesirable side effects lead to unsatisfied postoperative pain management outcome (Pediatr Anesth, 17, 2007, 756). The most commonly reported opioid-related side effects are vomiting (40%), pruritus (20-60%) (Anesthesiology, 77, 1992, 162; Drugs, 67, 2007, 2323), and constipation (15-90%) (Int J Clin Pract, 61, 2007, 1181). The potential life-threatening adverse event, respiratory depression, is less common (0.0013%) (Pediatr Anesth, 20, 2010, 119). The aim of this review was to evaluate prevention strategies that have been shown to decrease opioid side effects in pediatric patients during the postoperative period. Literature searches were conducted from 1984 to February 2013. Meta-analysis, systematic review, and randomized, placebo-controlled studies were obtained from PubMed and the Cochrane Library. The medical subject heading (MeSH) terms were opioid analgesics, adverse effects, pediatrics, children, side effects, and postoperative pain. Data from 62 studies were reviewed. The strategies that could effectively prevent and reduce opioid side effects in pediatric patients during the postoperative period included minimizing the amount of opioid consumption by a multimodal approach, opioid titration, using local anesthetic techniques and providing the specific prophylaxis for each side effect. © 2014 John Wiley & Sons Ltd.

    Asia is important as it accounts for more than half of the world population. The majority of Asian countries fall into the middle income category. As for cultural traditions, Asia is highly varied, with many languages spoken. The pattern of neurologic diseases in Asia is largely similar to the West, with some disease features being specific to Asia. Whereas Asia constitutes 60% of the world's population, it contains only 20% of the world's neurologists. This disparity is particularly evident in South and South East Asia. As for neurologic care, it is highly variable depending on whether it is an urban or rural setting, the level of economic development, and the system of health care financing. To help remedy the shortage of neurologists, most counties with larger populations have established training programs in neurology. These programs are diverse, with many areas of concern. There are regional organizations serving as a vehicle for networking in neurology and various subspecialties, as well as an official journal (Neurology Asia). The Asian Epilepsy Academy, with its emphasis on workshops in various locations, EEG certification examination, and fellowships, may provide a template of effective regional networking for improving neurology care in the region. © 2015 American Academy of Neurology.

    Many studies have shown that more severe symptoms and poorer insight are associated with poor treatment compliance in schizophrenia while severe symptoms may result in higher medication dosages. Since pharmacologic side effects may accompany greater medication compliance and higher medication dosage, the relationship between symptoms, insight and side effects deserves study. In this study, 174 inpatients diagnosed with schizophrenia were assessed during the week before hospital discharge from a large psychiatric hospital in Guangzhou, China. Symptoms were measured by the Positive and Negative Syndrome Scale for Schizophrenia (PANSS). Insight was assessed by the Insight and Treatment Attitudes Questionnaire (ITAQ). Pharmacologic side effects were assessed by the Treatment Emergent Symptoms Scale (TESS). Bivariate and multivariate regression models were used to examine the relationship of symptoms, insight and the interaction between the two, to the severity of side effects. As expected, the PANSS total score was significantly associated with poorer ITAQ scores and with more severe side effects, and on multivariate analysis both higher PANSS and lower ITAQ scores were associated with more severe side effects. Stepwise multiple linear regression analysis showed that the model with the PANSS total score alone explained 3.4% of the variance in side-effect scores, while adding the ITAQ increased the explained variance to 11.8%. Analysis of the interaction of symptoms and insight showed that patients with both more severe symptoms and high insight had the most severe side effects (B=.006, p=.008, R(2)=15.4%). More severe symptoms and greater insight among schizophrenic inpatients were both significantly if modestly associated with more severe pharmacologic side effects, the former presumably because of the need for higher doses of medication and the latter because of greater medication compliance. In addition, patients with both more severe symptoms and greater insight

    Predicting drug side effects is an important topic in the drug discovery. Although several machine learning methods have been proposed to predict side effects, there is still space for improvements. Firstly, the side effect prediction is a multi-label learning task, and we can adopt the multi-label learning techniques for it. Secondly, drug-related features are associated with side effects, and feature dimensions have specific biological meanings. Recognizing critical dimensions and reducing irrelevant dimensions may help to reveal the causes of side effects. In this paper, we propose a novel method 'feature selection-based multi-label k-nearest neighbor method' (FS-MLKNN), which can simultaneously determine critical feature dimensions and construct high-accuracy multi-label prediction models. Computational experiments demonstrate that FS-MLKNN leads to good performances as well as explainable results. To achieve better performances, we further develop the ensemble learning model by integrating individual feature-based FS-MLKNN models. When compared with other state-of-the-art methods, the ensemble method produces better performances on benchmark datasets. In conclusion, FS-MLKNN and the ensemble method are promising tools for the side effect prediction. The source code and datasets are available in the Additional file 1.

  17. The side effects of translational omics: overtesting, overdiagnosis, overtreatment.

    2016-03-01

    High-throughput technologies such as next-generation genomics, transcriptomics and proteomics are capable of generating massive amounts of data quickly, and at relatively low costs. It is tempting to use this data for various medical applications including preclinical disease detection and for prediction of disease predisposition. Pilot projects, initiated by various research groups and Google, are currently underway, but results with not be available for a few years. We here summarize some possible difficulties with these approaches, by using examples from already tried cancer and other screening programs. Population screening, especially with multiparametric algorithms, will identify at least some false positive parameters and screening programs will identify abnormal results in otherwise healthy individuals. Whole genome sequencing will identify genetic changes of unknown significance and may not predict accurately future disease predisposition if the disease is also influenced by environmental factors. In screening programs, if the disease is rare, the positive predictive value of the test will be low, even if the test has excellent sensitivity and specificity. False positive results may require invasive procedures to delineate. Furthermore, screening programs are not effective if the cancer grows quickly, and will identify indolent forms of the disease with slow-growing tumors. It has also been recently shown that for some cancers, more intensive and radical treatments do not usually lead to better clinical outcomes. We conclude that new omics testing technologies should avoid overdiagnosis and overtreatment and need to be evaluated for overall clinical benefit before introduction to the clinic.

  18. Cardiac Side-effects From Breast Cancer Radiotherapy.

    Taylor, C W; Kirby, A M

    2015-11-01

    Breast cancer radiotherapy reduces the risk of cancer recurrence and death. However, it usually involves some radiation exposure of the heart and analyses of randomised trials have shown that it can increase the risk of heart disease. Estimates of the absolute risks of radiation-related heart disease are needed to help oncologists plan each individual woman's treatment. The risk for an individual woman varies according to her estimated cardiac radiation dose and her background risk of ischaemic heart disease in the absence of radiotherapy. When it is known, this risk can then be compared with the absolute benefit of the radiotherapy. At present, many UK cancer centres are already giving radiotherapy with mean heart doses of less than 3 Gy and for most women the benefits of the radiotherapy will probably far outweigh the risks. Technical approaches to minimising heart dose in breast cancer radiotherapy include optimisation of beam angles, use of multileaf collimator shielding, intensity-modulated radiotherapy, treatment in a prone position, treatment in deep inspiration (including the use of breath-hold and gating techniques), proton therapy and partial breast irradiation. The multileaf collimator is suitable for many women with upper pole left breast cancers, but for women with central or lower pole cancers, breath-holding techniques are now recommended in national UK guidelines. Ongoing work aims to identify ways of irradiating pan-regional lymph nodes that are effective, involve minimal exposure of organs at risk and are feasible to plan, deliver and verify. These will probably include wide tangent-based field-in-field intensity-modulated radiotherapy or arc radiotherapy techniques in combination with deep inspiratory breath-hold, and proton beam irradiation for women who have a high predicted heart dose from intensity-modulated radiotherapy.

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

    Directory of Open Access Journals (Sweden)

    A. Vejux

    2008-07-01

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

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

    We review wildlife/mercury literature and our own research findings that demonstrate the relevance of wildlife toxicity data in protecting human health. Methylmercury affects wildlife through reduced adult survival and reproduction, aberrant behavior, immune system effects, and teratogenic effects. Methylmercury can readily cross the blood-brain barrier, is excreted into eggs in birds, and is transferred to young mammals across the placenta and in milk. Its principal effect on wildlife is on neurological functions. Wild mink (Mustela vison) and otter (Lutra canadensis) have died from methylmercury poisoning, with signs of poisoning including anorexia, loss of weight, incoordination, tremors, and convulsions, which are symptoms similar to those experienced by mercury-poisoned humans. Mammals also may experience tonic and clonic convulsions and an increase in fetal anomalies, again paralleling toxic problems in people. Antibody-producing cells can be suppressed by methylmercury. Microscopically, the most notable lesions are in the cerebrum. Extensive vacuolation of hepatocytes in the liver and necrosis and other changes in the appearance of the proximal convoluted tubules of the kidneys are often noted. When harp seals (Pagophilus groenlandicus) were dosed with methylmercury chloride the number of circulating erythrocytes decreased and white blood cell counts greatly increased. The poisoned seals also suffered from uremia, hyperproteinemia, hypercholesterolemia, hyperbilirubinemia, and elevations in lactic dehydrogenase and alkaline phosphatase. In birds, signs of methylmercury poisoning included emaciation and weakness in the extremities, which progressed until the birds died. Mercury poisoning in birds and mammals can be diagnosed from a combination of the signs of poisoning if the animal is still alive, the pathological effects seen in a gross necropsy, the histopathological effects seen with a microscope, and the concentrations of mercury in various tissues.

    Full Text Available One of the causes of frequent headaches in children is migraine headache. The prevention of headaches , will improve life equality in children. This study was designed to compare between treatment and side effects of sodium valproate and propranolol in preventing migraine headaches. This study was a randomized controlled clinical trial which carried out on 52 children who were reffered to out patient neurology clinic of the Ekbatan and Sina hospitals. All children with migraine who had headache during last 6 months were enrolled, and those who had received sodium valproate and propranolol previously, were excluded. The method was convenience sampling and the patients were divided into two groups with 26 patients: A and B for propranolol and sodium valproate respectively. Group A treated with propranolol and group B with sodium valproate for 8 weeks. The response to treatment was evaluated after 4 weeks. The study evaluated 52 children with migraine from 7-15 year’s old , 38.5% of cases were male and 61.5% female. Before treatment , the mean number of attacks was 5.61 months in group A and 8.73 months in group B. After treatment the number of attacks was declined in 21 cases (80.8% of group A and 19 cases (73.1% of group B. Severity of pain was improved in 18 cases (69.2% of group A and 15 cases (57.7% of group B. The incidence of vertigo was 3 cases (11.5% in group A and 2 cases (7.7% in group B. Abnormal liver enzymes test were detected in 11.5% of cases in the group B. CBC was abnormal in 7.7% of cases in the group B Sodium valproate and propranolol , both have the same therapeutic effects in prevention of migraine headeache in children. But side effects are different , and choice of either one depended on the effects consideration and contraindications of each one.

    Contractures are a disabling complication of neurological conditions that are commonly managed with stretch. The purpose of this systematic review was to determine the effectiveness of stretch for the treatment and prevention of contractures. The review is part of a more-detailed Cochrane review. Only the results of the studies including patients with neurological conditions are reported here. Electronic searches were conducted in June 2010 in the following computerized databases: Cochrane CENTRAL Register of Controlled Trials, Database of Abstracts of Reviews of Effects (DARE), Health Technology Assessment Database (HTA), MEDLINE, Cumulative Index to Nursing and Allied Health Literature (CINAHL), EMBASE, SCI-EXPANDED, and Physiotherapy Evidence Database (PEDro). The review included randomized controlled trials and controlled clinical trials of stretch applied for the purposes of treating or preventing contractures in people with neurological conditions. Two reviewers independently selected studies, extracted data, and assessed risk of bias. The primary outcome measures were joint mobility (range of motion) and quality of life. Secondary outcome measures were pain, spasticity, activity limitation, and participation restriction. Meta-analyses were conducted using random-effects models. Twenty-five studies met the inclusion criteria. These studies provide moderate-quality evidence that stretch has a small immediate effect on joint mobility (mean difference=3°, 95% confidence interval [CI]=0° to 5°) and high-quality evidence that stretch has little or no short-term or long-term effects on joint mobility (mean difference=1° and 0°, respectively, 95% CI=0° to 3° and -2° to 2°, respectively). There is little or no effect of stretch on pain, spasticity, and activity limitation. No studies were retrieved that investigated the effects of stretch for longer than 6 months. Regular stretch does not produce clinically important changes in joint mobility, pain

    This study examined the time dependence effects of exposure to radiofrequency radiation (RFR) emitted by standard GSM cellular phones on the cognitive functions of humans. A total of 48 healthy right-handed male subjects performed a spatial working memory task (that required either a left-hand or a right-hand response) while being exposed to one of two GSM phones placed at both sides of the head. The subjects were randomly divided into three groups. Each group was exposed to one of three exposure conditions: left-side of the head, right-side, or sham-exposure. The experiment consisted of 12 blocks of trials. Response times (RTs) and accuracy of the responses were recorded. It was found that the average RT of the right-hand responses under left-side exposure condition was significantly longer than those of the right-side and sham-exposure groups averaged together during the first two time blocks. These results confirmed the existence of an effect of exposure on RT, as well as the fact that exposure duration (together with the responding hand and the side of exposure) may play an important role in producing detectable RFR effects on performance. Differences in these parameters might be the reason for the failure of certain studies to detect or replicate RFR effects. (c) 2008 Wiley-Liss, Inc.

    Unexpected side effects of drugs are great concern in the drug development, and the identification of side effects is an important task. Recently, machine learning methods are proposed to predict the presence or absence of interested side effects for drugs, but it is difficult to make the accurate prediction for all of them. In this paper, we transform side effect profiles of drugs as their quantitative scores, by summing up their side effects with weights. The quantitative scores may measure the dangers of drugs, and thus help to compare the risk of different drugs. Here, we attempt to predict quantitative scores of drugs, namely the quantitative prediction. Specifically, we explore a variety of drug-related features and evaluate their discriminative powers for the quantitative prediction. Then, we consider several feature combination strategies (direct combination, average scoring ensemble combination) to integrate three informative features: chemical substructures, targets, and treatment indications. Finally, the average scoring ensemble model which produces the better performances is used as the final quantitative prediction model. Since weights for side effects are empirical values, we randomly generate different weights in the simulation experiments. The experimental results show that the quantitative method is robust to different weights, and produces satisfying results. Although other state-of-the-art methods cannot make the quantitative prediction directly, the prediction results can be transformed as the quantitative scores. By indirect comparison, the proposed method produces much better results than benchmark methods in the quantitative prediction. In conclusion, the proposed method is promising for the quantitative prediction of side effects, which may work cooperatively with existing state-of-the-art methods to reveal dangers of drugs.

    The purpose of this study was to examine, first, the movement actions performed during two different small-sided games and, second, their effects on a series of field endurance and technical tests. Thirty-four young soccer players (age: 13 ± 0.9 yrs; body mass: 62.3 ± 15.1 kg; height: 1.65 ± 0.06 m) participated in the study. Small-sided games included three-a-side (3 versus 3 players) and six-a-side (6 versus 6 players) games consisting of 10 bouts of 4 min duration with 3 min active recovery between bouts. Soccer player performance was evaluated using five field tests: a) 30m sprint, b) throw-in for distance, c) Illinois Agility Test, d) dribbling the ball and e) horizontal jump before, in the middle and after the implementation of both game situations. Heart rate was monitored during the entire testing session. Each game was also filmed to measure soccer movements within the game. The ANOVA analysis indicated that the three-a- side games displayed significantly higher heart rate values compared with the six-a-side games (p game condition (p games, there was a significant decline in sprint and agility performance (p game conditions significant alterations in the throw-in and the horizontal jump performance were observed (p games provide higher stimulus for physical conditioning and technical improvement than six-a-side games and their use for training young soccer players is recommended. Key pointsThree-a-side games display higher HR compared with six-a-side games.In the three-a-side games players performed more short passes, kicks, dribbles, tackles and scored more goals compared with the six-a-side games.Impairment in endurance and field test performance was observed mainly after three-a-side games.The use of the three-a-side games to develop physical fitness and technique in young soccer players is recommended.

    Our aim was to evaluate Wikipedia page visits in relation to the most common neurological disorders by determining which factors are related to peaks in Wikipedia searches for these conditions. Millions of people worldwide use the internet daily as a source of health information. Wikipedia is a popular free online encyclopedia used by patients and physicians to search for health-related information. The following Wikipedia articles were considered: Alzheimer's disease; Amyotrophic lateral sclerosis; Dementia; Epilepsy; Epileptic seizure; Migraine; Multiple sclerosis; Parkinson's disease; Stroke; Traumatic brain injury. We analyzed information regarding the total article views for 90 days and the rank of these articles among all those available in Wikipedia. We determined the highest search volume peaks to identify possible relation with online news headlines. No relation between incidence or prevalence of neurological disorders and the search volume for the related articles was found. Seven out of 10 neurological conditions showed relations in search volume peaks and news headlines. Six out of these seven peaks were related to news about famous people suffering from neurological disorders, especially those from showbusiness. Identification of discrepancies between disease burden and health seeking behavior on Wikipedia is useful in the planning of public health campaigns. Celebrities who publicly announce their neurological diagnosis might effectively promote awareness programs, increase public knowledge and reduce stigma related to diagnoses of neurological disorders.

    The central nervous system regulates food intake, homoeostasis of glucose and electrolytes, and starts the sensations of hunger and satiety. Different nutritional factors are involved in the pathogenesis of several neurological diseases. Patients with acute neurological diseases (traumatic brain injury, cerebral vascular accident hemorrhagic or ischemic, spinal cord injuries, and cancer) and chronic neurological diseases (Alzheimer's Disease and other dementias, amyotrophic lateral sclerosis, Parkinson's Disease) increase the risk of malnutrition by multiple factors related to nutrient ingestion, abnormalities in the energy expenditure, changes in eating behavior, gastrointestinal changes, and by side effects of drugs administered. Patients with acute neurological diseases have in common the presence of hyper metabolism and hyper catabolism both associated to a period of prolonged fasting mainly for the frequent gastrointestinal complications, many times as a side effect of drugs administered. During the acute phase, spinal cord injuries presented a reduction in the energy expenditure but an increase in the nitrogen elimination. In order to correct the negative nitrogen balance increase intakes is performed with the result of a hyper alimentation that should be avoided due to the complications resulting. In patients with chronic neurological diseases and in the acute phase of cerebrovascular accident, dysphagia could be present which also affects intakes. Several chronic neurological diseases have also dementia, which lead to alterations in the eating behavior. The presence of malnutrition complicates the clinical evolution, increases muscular atrophy with higher incidence of respiratory failure and less capacity to disphagia recuperation, alters the immune response with higher rate of infections, increases the likelihood of fractures and of pressure ulcers, increases the incapacity degree and is an independent factor to increase mortality.

    Dimethyl fumarate is an orally available treatment option for relapsing-remitting multiple sclerosis (MS) in a new formulation with improved gastroenteric coating. The mode of action comprises immunomodulatory effects and an activation of nuclear (erythroid-derived 2) related factor mediated antioxidative response pathways leading to additional cytoprotective effects. In two pivotal phase III trials, dimethyl fumarate, 240 mg twice daily, reduced relapse rates by about 50 % as compared with placebo. In the DEFINE trial, progression of disability was also significantly reduced. Both trials demonstrated a significant reduction of gadolinium-enhanced lesions as well as T2 lesions on cranial MRI. The studies revealed a beneficial safety profile of dimethyl fumarate. The most prevalent side effects were transient flushing and gastrointestinal tract irritation. Dimethyl fumarate has recently been approved in the USA for the treatment of relapsing-remitting MS. The compound is a welcome addition to the immunomodulatory treatment armamentarium for MS patients and physicians alike.

    The realization that mitigation efforts to reduce carbon dioxide emissions have, until now, been relatively ineffective has led to an increasing interest in climate engineering as a possible means of preventing the potentially catastrophic consequences of climate change. While many studies have addressed the potential effectiveness of individual methods there have been few attempts to compare them. Here we use an Earth system model to compare the effectiveness and side effects of afforestation, artificial ocean upwelling, ocean iron fertilization, ocean alkalinization and solar radiation management during a high carbon dioxide-emission scenario. We find that even when applied continuously and at scales as large as currently deemed possible, all methods are, individually, either relatively ineffective with limited (stopped without causing rapid climate change. Our simulations suggest that the potential for these types of climate engineering to make up for failed mitigation may be very limited.

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

    1976-09-01

    In developing countries, especially Latin America, women obtain oral contraceptives without a physician's prescription. While these women experience more side effects, they have fewer accidental pregnancies than women who obtain the pills through a physician/prescription. A probability sample of 6692 Colombian women in Bogota were interviewed in 1974. Almost 1 in 20 of all women, and almost 1 in 13 of those married or living in a union, said they began using the pill on their own as their first method of contraception. The characteristics of the women without prescriptions were similar to those with, but self-prescribers were slightly older, had more children, and were less educated. 7 in 10 women of both groups continued pill use for 1 year; about 6 in 10 still used the pill after 2 years. Both groups gave side effects as their reason for discontinuation. The most frequently cited side effect was headache. None of the women reported the more serious complications, thrombophlebitis and thromboembolism. Women who did not begin with medical advice were less likely to seek it when they had side effects attributed to the pill. Half as many self-prescribers (24%), as users with a prescription (46%), reported visiting a private physician about side effects. 11% self-prescribers, compared with 25%, sought other professional help.

    Identification of underlying mechanisms behind drugs side effects is of extreme interest and importance in drugs discovery today. Therefore machine learning methodology, linking such different multi features aspects and able to make predictions, are crucial for understanding side effects. In this paper we present DrugClust, a machine learning algorithm for drugs side effects prediction. DrugClust pipeline works as follows: first drugs are clustered with respect to their features and then side effects predictions are made, according to Bayesian scores. Biological validation of resulting clusters can be done via enrichment analysis, another functionality implemented in the methodology. This last tool is of extreme interest for drug discovery, given that it can be used as a validation of the clusters obtained, as well as for the study of new possible interactions between certain side effects and nontargeted pathways. Results were evaluated on a 5-folds cross validations procedure, and extensive comparisons were made with available datasets in the field: Zhang et al. (2015), Liu et al. (2012) and Mizutani et al. (2012). Results are promising and show better performances in most of the cases with respect to the available literature.

    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.

    Evidence suggests that hypnosis is an effective intervention for reducing distress, pain and other side effects associated with cancer and its treatment. However, hypnosis has failed to be adopted into standard clinical practice. This study (n=115) investigated overall intentions to use hypnosis to control side effects of cancer and its treatment, as well as demographic predictors of such intentions among healthy volunteers. Results suggest that the vast majority of patients (89%) would be willing to use hypnosis to control side effects associated with cancer treatment. Mean intention levels did not differ by gender, ethnicity, education or age. These results indicate that in the general public, there is a willingness to consider the use of hypnosis, and that willingness is not determined by demographic factors. This broad acceptance of hypnosis argues for more widespread dissemination. PMID:21049742

    Stroke is one of the most common affliction of patients with neurological symptoms. Rehabilitation of stroke patients is a difficult task. Our knowledge on rehabilitation has recently improved with the emergence of data from new neuroimaging techniques. A prospective, double blind, cross over, placebo, controlled study on 8 patients with pure motor hemiparesia, is conducted to determine the influence of a single dose of fluoxetine on motor performance and cerebral activation of patients recovering from stroke. Each patient undergoes two functional magnetic resonance imaging (fMRI) examinations, one under fluoxetine and one under placebo. A single dose of fluoxetine is enough to modulate cerebral sensori-motor activation and significantly improves motor skills of the affected side. Further studies are required to investigate the effect of chronic administration of fluoxetine on motor function.

    A comprehensive analysis is performed to evaluate the effect of weight, height and body mass index (BMI) of occupants on side impact injuries at different body regions. The accident dataset for this study is based on the National Automotive Sampling System-Crashworthiness Data System (NASS-CDS) for accident year 2000-08. The mean BMI values for driver and front passenger are estimated from all types of crashes using NASS database, which clearly indicates that mean BMI has been increasing over the years in the USA. To study the effect of BMI in side impact injuries, BMI was split into three groups namely (1) thin (BMI30). For more clear identification of the effect of BMI in side impact injuries, a minimum gap of three BMI is set in between each adjacent BMI groups. Car model years from MY1995-1999 to MY2000-2008 are chosen in order to identify the degree of influence of older and newer generation of cars in side impact injuries. Impact locations particularly side-front (F), side-center (P) and side-distributed (Y) are chosen for this analysis. Direction of force (DOF) considered for both near side and far side occupants are 8 o'clock, 9 o'clock, 10 o'clock and 2 o'clock, 3 o'clock and 4 o'clock respectively. Age <60 years is also one of the constraints imposed on data selection to minimize the effect of bone strength on the occurrence of occupant injuries. AIS2+ and AIS3+ injury risk in all body regions have been plotted for the selected three BMI groups of occupant, delta-V 0-60kmph, two sets (old and new) of car model years. The analysis is carried with three approaches: (a) injury risk percentage based on simple graphical method with respect to a single variable, (b) injury distribution method where the injuries are marked on the respective anatomical locations and (c) logistic regression, a statistical method, considers all the related variables together. Lower extremity injury risk appears to be high for thin BMI group. It is found that BMI does not have much

    Perceptions among women with breast cancer about the relative importance of different potential chemotherapy side effects is not well understood. A survey was performed by women receiving chemotherapy for breast cancer. Grade I/II (mild to moderate) and III/IV (moderate to severe) descriptions of nine common chemotherapy side effects were assigned preference weights using the standard gamble technique. For each hypothetical side effect, patients could choose to stay in the respective side effect state or take a gamble between full health (probability p) or being dead (1 - p). For each side effect, p was varied until the patient was indifferent between these options. The survey also included questions about the importance of survival, slowing cancer growth, and quality of life. This analysis included 69 patients; mean age 54 years (range 35-84), representing all cancer stages. Standard gamble preferences were lowest (i.e., least preferred) for grade III/IV nausea/vomiting (0.621), indicating that patients would, on average, risk a 38 % chance of being dead to avoid having grade III/IV nausea/vomiting for the rest of their lives. The next least preferred side effects were grade III/IV diarrhea (0.677) and grade III/IV sensory neuropathy (0.694). Survival appeared more important than slowing cancer growth and maintaining quality of life across cancer stages. Nevertheless, patients with advanced disease placed less importance on survival (p = 0.09) and higher importance on quality of life (p = 0.05). These standard gamble utilities provide unique insights into chemotherapy toxicities from the patient perspective. Differences in the relative importance of overall survival and quality of life with treatment existed between patients with different stages of disease. These studies should be expanded as the data may also be used to calculate quality-adjusted life expectancy in cost-effectiveness evaluations of breast cancer chemotherapies.

    2010-01-01

    Side effects of anabolic steroids with relevance in forensic medicine are mainly due to life-threatening health risks with potential fatal outcome and cases of uncertain limitations of criminal liability after steroid administration. Both problems are typically associated with long-term abuse and excessive overdose of anabolic steroids. Side effects may be due to direct genomic or nongenomic activities (myotrophic, hepatotoxic), can result from down-regulation of endogenous biosynthesis (antiandrogenic) or be indirect consequence of steroid biotransformation (estrogenic).Logically, there are no systematic clinical studies available and the number of causally determined fatalities is fairly limited. The following compilation reviews typical abundant observations in cases where nonnatural deaths (mostly liver failure and sudden cardiac death) were concurrent with steroid abuse. Moreover, frequent associations between structural characteristics and typical side effects are summarized.

    Full Text Available Attention deficit hyperactivity disorder (ADHD is one of the most common neurobehavioral disorders of childhood and adolescence. Classically, stimulants have been used in the treatment of this condition. Atomoxetine (Strattera; Eli Lilly and Company is a selective norepinephrine reuptake inhibitor (SNRI, one of the first medications in the nonstimulant class of medications that has been approved by the FDA for the treatment of ADHD. Atomoxetine is a phenoxypropylamine derivative and is structurally related to the antidepressant fluoxetine. The common side effects reported with the use of atomoxetine include mainly GI disturbances. Cardiovascular side effects are less commonly reported. The increase in the noradrenergic tone may explain some of the side effects noted with the use of this medication. Here, we present a case of a patient who presented with syncope, orthostatic hypotension, and tachycardia and discuss the various clinical implications based on the pharmacokinetics and pharmacodynamics of the drug.

    2014-05-01

    Antibiotics are frontline therapy against microbial infectious diseases. Many antibiotics are known to cause several side effects in humans. Ribosomal RNA (rRNA) is the main target of antibiotics that inhibit protein synthesis. According to the endosymbiont theory, mitochondrion is of bacterial origin and their molecular and structural components of the protein expression system are almost similar. It has been observed that the rate of mutations in mitochondrial rRNA is higher as compared to that of nuclear rRNA. The presence of these mutations may mimic prokaryotic rRNA structure and bind to antibiotics targeted to ribosomes of bacteria. Mitochondrial functions are compromised hence may be one of the major causes of side effects observed during antibiotic therapy. The current review had summarized the studies on the role of antibiotics on mitochondrial functions and its relevance to the observed side effects in physiological and pathological conditions.

    Attention deficit hyperactivity disorder (ADHD) is one of the most common neurobehavioral disorders of childhood and adolescence. Classically, stimulants have been used in the treatment of this condition. Atomoxetine (Strattera; Eli Lilly and Company) is a selective norepinephrine reuptake inhibitor (SNRI), one of the first medications in the nonstimulant class of medications that has been approved by the FDA for the treatment of ADHD. Atomoxetine is a phenoxypropylamine derivative and is structurally related to the antidepressant fluoxetine. The common side effects reported with the use of atomoxetine include mainly GI disturbances. Cardiovascular side effects are less commonly reported. The increase in the noradrenergic tone may explain some of the side effects noted with the use of this medication. Here, we present a case of a patient who presented with syncope, orthostatic hypotension, and tachycardia and discuss the various clinical implications based on the pharmacokinetics and pharmacodynamics of the drug.

    Full Text Available omorbid psychiatric disorders, frequent hospitalization, multiple outpatient treatment, prior history of hypertension, obesity and lipid dysregulation are associated with higher risk of metabolic syndrome in children. Side effects of antipsychotic drugs and their management have recently become a major subject of research due to enhanced antipsychotic drug usage in child and adolescents. Prevention strategies are usually preferred to secondary or tertiary strategies in the management of metabolic syndrome associated with antipsychotic drugs. Clinicians should present multidisciplinary approach to endocrine and metabolic side effects due to antipsychotic use in pediatric patient groups and avoid multiple drug use in such patients. In this paper, we briefly reviewed metabolic side effects of second generation antipsychotic drugs in child and adolescent population, possible mechanisms of susceptibility to metabolic syndrome and pharmacological and non pharmacological treatment approach to prevention of weight gain.

    Lead is found in small but appreciable quantities in air, soil, drinking water, and food. Exposure to such amounts of lead does not lead to acute lead toxicity but produces subtle effects particularly in children. The aim of this study was to investigate the effects of blood lead level on biochemical and hematological parameters in children with neurological diseases in Western Maharashtra, India, and to estimate the blood lead level by liver and kidney function tests and hematological parameters in children with neurological disorders admitted to the pediatric ward and compare them with healthy controls. In this study, 30 children with various neurological disorders admitted to the pediatric ward of Smt. Kashibai Navale Medical College and General Hospital, Pune, Maharashtra, India, were compared with 30 age- and sex-matched healthy controls. Four milliliters of venous blood was collected for estimation of blood lead level, and biochemical and hematological parameters were determined using standard methods. Blood lead level was significantly increased in the study group (pfood habits and limit hand-to-mouth activities to prevent lead intoxication.

    Cerebral ischemia and reperfusion causes physiological and biochemical changes in the neuronal cells that will eventually lead to cell damage. Evidence indicates that exercise reduces the ischemia and reperfusion-induced brain damages in animal models of stroke. In the present study, the effect of exercise preconditioning on brain edema and neurological movement disorders following the cerebral ischemia and reperfusion in rats was investigated. Twenty-one adult male wistar rats (weighing 260-300 g) were randomly divided into three groups: sham operated, exercise plus ischemia, and ischemia group (7 rats per group). The rats in exercise group were trained to run on a treadmill 5 days a week for 4 weeks. Transient focal cerebral ischemia and reperfusion were induced by middle cerebral artery occlusion (MCAO) for 60 minutes, followed by reperfusion for 23 hours. After 24 hours ischemia, movement disorders were tested by a special neurological examination. Also, cerebral edema was assessed by determining the brain water content. The results showed that pre-ischemic exercise significantly reduced brain edema (Pexercise preconditioning decreased the neurological movement disorders caused by brain ischemia and reperfusion (Pexercise had neuroprotective effects against brain ischemia and reperfusion-induced edema and movement disorders. Thus, it could be considered as a useful strategy for prevention of ischemic injuries, especially in people at risk.

  18. Norms inform mental state ascriptions: A rational explanation for the side-effect effect.

    Theory of mind, the capacity to understand and ascribe mental states, has traditionally been conceptualized as analogous to a scientific theory. However, recent work in philosophy and psychology has documented a "side-effect effect" suggesting that moral evaluations influence mental state ascriptions, and in particular whether a behavior is described as having been performed 'intentionally.' This evidence challenges the idea that theory of mind is analogous to scientific psychology in serving the function of predicting and explaining, rather than evaluating, behavior. In three experiments, we demonstrate that moral evaluations do inform ascriptions of intentional action, but that this relationship arises because behavior that conforms to norms (moral or otherwise) is less informative about underlying mental states than is behavior that violates norms. This analysis preserves the traditional understanding of theory of mind as a tool for predicting and explaining behavior, but also suggests the importance of normative considerations in social cognition. 2010 Elsevier B.V.

    Not much is known about the side effects of mitomycin C (MMC), an anti-fibrogenetic agent, in the upper aerodigestive tract. However, its use in ophthalmology is widely known and without quantitatively important side effects. A literature review was performed for side effects of MMC in the upper aerodigestive tract. Forty-six articles, describing the use of MMC to prevent scarring, were retracted from PubMed. Thirty-two are human studies. MMC is used in different concentrations (0.1-10 mg/ml) with different application times (2-5 min) and frequencies (up to 4 times). Five hundred and thirty-eight patients were included in those publications, of whom 19 developed side effects (3.53%). No side effects developed in studies, where post-application irrigation with saline was reported. The longest mean follow-up period is 75.5 months. Direct relations between the reported side effects and MMC seem absent in most studies. Serious complications seem to occur when MMC is used in high concentrations. Unfortunately, sometimes crucial information is lacking. One patient was described who supposedly developed laryngeal carcinoma after repeated treatment of hyperkeratosis and anterior commissure webbing. Animal studies show that excessive fibrin production can lead to acute airway obstruction. In conclusion, topical application of MMC on a wound with consecutive irrigation with saline can be performed safely to prevent scar formation in circular structures of the upper aerodigestive tract. Long-term yearly control of the application site seems advisable.

    Clozapine is an antipsychotic with superior efficacy in treatment refractory patients, and has unique anti-suicidal properties and a low propensity to cause extrapyramidal side-effects. Despite these advantages, clozapine utilization is low. This can in part be explained by a number of potentially lethal side effects of clozapine. Next to psychiatrists nurses play a crucial role in the long-term management of patients with schizophrenia. It is therefore important that nurses know, inform and monitor patients about the specific side-effects of clozapine. A recent study of psychiatrists published in 2011 has shown that there was a gap in the knowledge about side-effects of clozapine. The knowledge about side-effects of clozapine in nurses has never been studied. This cross-sectional study evaluated the knowledge base regarding the safety of clozapine, and its potential mediators, of psychiatric nurses in 3 psychiatric hospitals in Belgium with a specifically developed questionnaire based on the literature and expert opinion (3 clozapine experts). A total of 85 nurses completed the questionnaire. The mean total score was 6.1 of a potential maximum score of 18. Only 3 of the 18 multiple choice knowledge questions were answered correctly by more than 50% of nurses. Only 24.9% of participants passed the test (>50% correct answers). Nurses working on psychosis units were more likely to pass the test (xx.y% vs yy.z%, p=0.0124). There was a trend that nurses with a lower nursing diploma were more likely to fail the test (p=0.0561). Our study clearly identifies a large gap in the basic knowledge of psychiatric nurses about clozapine and its side-effects. Knowledge could be increased by more emphasis on the topic in nurse's training curricula as well as targeted onsite training. Only 23.5% of participants indicate that there was sufficient information in their basic nursing training. Copyright © 2015 Elsevier Inc. All rights reserved.

  1. Parent perceptions of managing child behavioural side-effects of cancer treatment: a qualitative study.

    Very little research has examined the role of parenting in managing behavioural side-effects of cancer treatment. The purpose of this paper was to explore parent perceptions of (a) parenting in the context of childhood cancer; (b) the parenting strategies used in the context of managing child behavioural side-effects of cancer treatment; and (c) the perceived impact that cancer-specific parenting strategies have on child behaviour. Participants were 15 mothers of children aged 2-6 years in the maintenance phase of treatment for acute lymphoblastic leukaemia at the Royal Children's Hospital Children's Cancer Centre, Melbourne, Australia. Mothers participated in a one-on-one semi-structured telephone interview using an interview guide which included questions on parenting in the context of childhood cancer, specifically in relation to behavioural side-effects (problems with behaviour, sleep and eating) and any perceived impact cancer-specific parenting may have on the ill child. Many parents reported that following their child's cancer diagnosis, they had to implement a suite of 'new' strategies that 'pre-diagnosis' were used only in moderation, if at all. The most salient theme that emerged was parents' perception that their parenting became more lax since their child's diagnosis. Parents further reported specific parenting strategies for each of the main child behavioural side-effects of cancer treatment. Data from the current qualitative exploratory study highlight the role of specific parenting strategies in managing or assisting child behavioural side-effects of cancer treatment. Further quantitative research is needed to more fully examine the association between parenting and child behavioural outcomes in order to develop modifiable approaches to improving child behavioural side-effects in a paediatric oncology context. © 2014 John Wiley & Sons Ltd.

    Full Text Available The blunt end with side hole irrigation needles have some advantages. They can be placed close to irrigation area, produce turbulent motion of irrigation material, and not push debris to apical. There is no data about the effectiveness of blunt end with side hole irrigation needle to eliminate root canal bacteria in vivo, therefore the research about effectivity of this needle compare to conventional irrigation needle was permormed. In this study 12 samples were used and divided into two groups. The conventional irrigation needle in the first group was used as control and the blunt end with side hole needle was used in the second group. The bacteriological sampling and colony counting was conducted. The paired t-test analysis before and after irrigation showed significant difference on the first and second group. The result indicated that blunt end with side hole needle more effective in eliminating root canal bacteria than conventional needle. Supporting to this study a software of fluent had been done in vitro. The result showed blunt end with side hole needle produced turbulent motion of irrigating liquid and the conventional needle produced laminar motion.

    Recent studies on glass-forming polymers near interfaces have emphasized the importance of molecular features such as chain stiffness, side-groups, molecular packing, and associated changes in fragility as key factors that govern the magnitude of Tg changes with respect to the bulk in polymer thin films. However, how such molecular features are coupled with substrate and free surface effects on Tg in thin films remains to be fully understood. Here, we employ a chemically specific coarse-grained polymer model for methacrylates to investigate the role of side-group volume on glass formation in bulk polymers and supported thin films. Our results show that bulkier side-groups lead to higher bulk Tg and fragility and are associated with a pronounced free surface effect on overall Tg depression. By probing local Tg within the films, however, we find that the polymers with bulkier side-groups experience a reduced confinement-induced increase in local Tg near a strongly interacting substrate. Further analyses indicate that this is due to the packing frustration of chains near the substrate interface, which lowers the attractive interactions with the substrate and thus lessens the surface-induced reduction in segmental mobility. Our results reveal that the size of the polymer side-group may be a design element that controls the confinement effects induced by the free surface and substrates in supported polymer thin films. Our analyses provide new insights into the factors governing polymer dynamics in bulk and confined environments.

    Inhaled corticosteroids are used as one of the first-line drug therapy in patients with asthma. However, their long-term use is associated with various oropharyngeal and systemic side and adverse effects. Design of pro-soft drug is one of the strategies, which was adopted in the design of ciclesonide for mitigation of side effects usually observed with the use of inhaled corticosteroids. Ciclesonide, a pro-soft drug, is converted to an active metabolite desisobutyryl-ciclesonide in the lungs. The anti-inflammatory effect of desisobutyryl-ciclesonide is much higher than ciclesonide, and therefore, the local effect of the metabolite is higher with lower systemic side effects. Ciclesonide has favorable pharmacokinetic and pharmacodynamic properties as inhaled corticosteroid including low oral bioavailability, high plasma protein binding and rapid systemic clearance, high pulmonary deposition and distribution and long pulmonary residence duration. These advantageous properties make ciclesonide a very effective treatment option with low side effects. Various clinical studies support safety and efficacy of ciclesonide use in mild, moderate, and severe asthma patients. Copyright © 2016 American Pharmacists Association®. Published by Elsevier Inc.

    A total of 52 healthy, adult volunteers were randomly assigned to five treatment groups to be treated twice daily for 4 days with 100 mg of amantadine, 100 mg of rimantadine, 4 mg of chlorpheniramine or placebo alone, or 100 mg of amantadine in combination with chlorpheniramine. The results of tests measuring performance on tasks of attention, reasoning, and memory were unaffected by treatment. Subjective side effects in recipients of amantadine, rimantadine, and chlorpheniramine were comparable and minimal. Side effects appeared to be enhanced in subjects receiving both amantadine and chlorpheniramine. PMID:7044294

    Recent campaigns try to reduce social stigma associated with persons living with HIV. For example, a German campaign raised awareness that infection is unlikely in low-risk day-to-day interactions. Research has yet to show that there are no harmful side effects. This is essential because such messages promote a less threatening picture of HIV and thus may unintentionally increase complacency. We tested the possible side effects on the willingness to have sex without condoms. An experiment was conducted in which participants were exposed to anti-stigma messages or not. Anti-stigma messages did not elicit an increase in the willingness to have sex without condoms.

    This study analyses the outcome of the continuous improved occupant protection over the last two decades for front seat near side occupants in side impacts based on a real world driven working process. The effectiveness of four generations of improved side impact protection are calculated based on data from Volvo's statistical accident database of Volvo Cars in Sweden. Generation I includes vehicles with a new structural and interior concept (SIPS). Generation II includes vehicles with structural improvements and a new chest airbag (SIPSbag). Generation III includes vehicles with further improved SIPS and SIPSbag as well as the new concept with a head protecting Inflatable Curtain (IC). Generation IV includes the most recent vehicles with further improvements of all the systems plus advanced sensors and seat belt pretensioner activation. Compared to baseline vehicles, vehicles of generation I reduce MAIS2+ injuries by 54%, generation II by 61% and generation III by 72%. For generation IV effectiveness figures cannot be calculated because of the lack of MAIS2+ injuries. A continuous improved performance is also seen when studying the AIS2+ pelvis, abdomen, chest and head injuries separately. By using the same real world driven working process, future improvements and possibly new passive as well as active safety systems, will be developed with the aim of further improved protection to near side occupants in side impacts.

    2017-03-01

    Full Text Available Law enforcement decision-makers rely on intelligence analysts to produce intelligence products that are clear. Yet, intelligence analysts live in a world characterised by ambiguity and information overload. This paper examines the intellectual journey that leads to clarity of thought, and the effect of the dark side of clarity on producing knowledge for decision-making. The paper asked, how does the dark side of clarity manifest itself to analyst and decision-maker? The result is counterintuitive; while the bright side of clarity is expected, and demanded because of its benefit to decision-making, the dark side of clarity co-exists in the shadows of certainty and makes it difficult to think critically. Neither analyst nor decision-maker is likely aware of this negative effect. To make this dark side of clarity visible, recommendations are made that begin with raising analyst awareness by augmenting existing training. Then, decision-maker awareness can be approached through training and facilitated coaching.

    Opioids cause gastrointestinal (GI) symptoms such as nausea, vomiting, pain, and (in 40 percent) constipation that diminish patients' quality of life. Outside traditional surveys, little is known about the opioid-induced constipation (OIC) patient experience and its impact on pain management. The purpose of this study was to use data from social media platforms to qualitatively examine patient beliefs about OIC and other prominent GI side effects, their impact on effective pain management and doctor-patient interaction. The authors collected Tweets from March 25 to July 31, 2014, and e-forum posts from health-related social networking sites regardless of timestamp. The authors identified specific keywords related to opioids and GI side effects to locate relevant content in the dataset, which was then manually coded using ATLAS.ti software. The authors examined 2,519,868 Tweets and more than 1.8 billion e-forum posts, of which, 88,586 Tweets and 9,767 posts satisfied the search criteria. Three thousand three individuals experienced opioidinduced GI side effects, mostly related to phenanthrenes (n = 1,589), and 1,274 (42.4 percent) individuals described constipation. Over-the-counter medications and nonevidence-based natural approaches were most commonly used to alleviate constipation. Many individuals questioned, rotated, reduced, or stopped their opioid treatments as a result of their GI side effects. Investigation of social media reveals a struggle to balance pain management with opioid-induced GI side effects, especially constipation. Individuals are often unprepared to treat OIC, to modify opioid regiments without medical advice, and to resort to using natural remedies and treatments lacking scientific evidence of effectiveness. These results identify opportunities to improve physician-patient communication and explore effective treatment alternatives.

    Dysaesthesiae of the scalp and neurological abnormality after mobile phone use have been reported previously, but the roles of the phone per se or the radiations in causing these findings have been questioned. We report finding a neurological abnormality in a patient after accidental exposure of the left side of the face to mobile phone radiation [code division multiple access (CDMA)] from a down-powered mobile phone base station antenna. He had headaches, unilateral left blurred vision and pupil constriction, unilateral altered sensation on the forehead, and abnormalities of current perception thresholds on testing the left trigeminal ophthalmic nerve. His nerve function recovered during 6 months follow-up. His exposure was 0.015-0.06 mW/cm(2) over 1-2 h. The implications regarding health effects of radiofrequency radiation are discussed.

    School closure along with mass prophylactic oseltamivir treatment of pupils have been used in England and elsewhere to contain school outbreaks of influenza A(H1N1)v. We evaluated the protective effect, compliance with and side effects of oseltamivir chemoprophylactic treatment with a ten-day course of 1x 75mg given to 11-12-year-old pupils in one school year in a secondary school in South West England closed for ten days in response to a symptomatic laboratory-confirmed pupil. We distributed a questionnaire to pupils in the affected school year in class after the school had re-opened. Questions included symptoms of flu-like illness, compliance with chemoprophylaxis and side effects. All present on the day, 248 (93.2%) participated. Compliance with chemoprophylaxis was high, 77% took the full course, 91% took at least seven days. Fifty-one percent experienced symptoms such as feeling sick (31.2%), headaches (24.3%) and stomach ache (21.1%). Although some children were ill with flu-like symptoms, those tested did not have A(H1N1)v infection. Compliance with oseltamivir chemoprophylaxis was high, although likely side effects were common. The burden of side effects needs to be considered when deciding on mass oseltamivir chemoprophylaxis in children especially given that the symptoms of A(H1N1)v influenza are generally mild.

    2014-08-01

    Full Text Available 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. Aim: 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. Results: 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. Conclusion: 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.

    Human research investigating the impact of intranasal oxytocin on psychological processes has accelerated over the last two decades. No review of side effects, subjective reactions and safety is available. A systematic review of 38 randomised controlled trials conducted between 1990 and 2010 that investigated the central effects of intranasal oxytocin was undertaken. A systematic search for reports of adverse reactions involving intranasal oxytocin was also completed. Since 1990, research trials have reported on N=1529 (79% male) of which 8% were participants with developmental or mental health difficulties. Dosages ranged from 18 to 40 IU, mainly in single doses but ranged up to 182 administrations. Diverse methods have been used to screen and exclude participants, monitor side effects and subject reactions. Side effects are not different between oxytocin and placebo and participants are unable to accurately report on whether they have received oxytocin and placebo. Three case reports of adverse reactions due to misuse and longer-term use of intranasal oxytocin were reported. The evidence shows that intranasal oxytocin: (1) produces no detectable subjective changes in recipients, (2) produces no reliable side-effects, and (3) is not associated with adverse outcomes when delivered in doses of 18-40 IU for short term use in controlled research settings. Future research directions should include a focus on the dosage and duration of use, and application with younger age groups, vulnerable populations, and with females. Copyright © 2011 Elsevier Ltd.

    Full Text Available Introduction: Acne vulgaris is an inflammatory disease of pilosebaceous folicles. Tretinoin is used as one of the topical treatments for acne vulgaris. It has different cutaneous side effects such as erythema, scaling, irritation and photosensitivity. The aim of this study was to evaluate the efficacy of oral Vitamine E in preventing the cutaneous side effects of topical tretinoin in acne patients.
    Methods: A clinical trial was performed in AI-Zahra Hospital in Isfahan for six months in 2000. 80 patients with mild to moderate facial acne were randomized into 2 groups. Group 1 (controls received topical solution of tretinoin 0.05 percent nightly and group 2 (cases received daily oral 100mg of Vit. E in addition. All patients were followed at 1, 4 and 6 weeks after initiation of treatment. Children under 12 years old, pregnant or lactating women were excluded.
    Results: At the end of one week, no cutaneous side effects were observed in 25 percent (10 of group 1 and 15 percent (6 of group 2 (P > 0.05. At the end of 4 weeks, 25 percent (10 of group 1 and 60 percent (24 of group 2 were without any cutaneous complications, while at the end of 6 weeks, 35 percent (14 of group 1 in comparison to 75 percent (30 of group 2 were free of any cutaneous side effects (P < 0.05. The most common side effect in both groups was exfoliation.
    Discussion: Daily oral 100 mg of Vit. E has been effective in preventing cutaneous complications of topical tretinoin in acne management, but there is a delay of one week in its onset of action. Meanwhile, Vitamine E is a safe modality with no undesirable effects in acne patients.

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

    Green, David G

    2014-01-01

    Why do things go wrong? Why, despite all the planning and care in the world, do things go from bad to worse? This book argues that it is because we are like the ants. Just as ants create an anthill without being aware of it, unintended side effects of human activity create all manner of social trends and crises. The book traces the way these trends emerge and the role they play in some of the major issues of our time. One of the greatest challenges today is the complexity of our social and economic systems. Every action has side effects that people often ignore or fail to see. The book examines the ways in which limitations in our thinking and behaviour lead to unintended side effects. It looks at the role played by complex networks of interactions. Finally, it looks at the way side effects of new technologies, especially computers and communication, have created an Information Revolution, the full repercussions of which are yet to be seen. In our race to create new technologies and sustain indefinite economi...

    Full Text Available Abstract Background This study is part of a nationwide evaluation of complementary medicine in Switzerland (Programme Evaluation of Complementary Medicine PEK and was funded by the Swiss Federal Office of Public Health. The main objective of this study is to investigate patient satisfaction and perception of side effects in homeopathy compared with conventional care in a primary care setting. Methods We examined data from two cross-sectional studies conducted in 2002–2003. The first study was a physician questionnaire assessing structural characteristics of practices. The second study was conducted on four given days during a 12-month period in 2002/2003 using a physician and patient questionnaire at consultation and a patient questionnaire mailed to the patient one month later (including Europep questionnaire. The participating physicians were all trained and licensed in conventional medicine. An additional qualification was required for medical doctors providing homeopathy (membership in the Swiss association of homeopathic physicians SVHA. Results A total of 6778 adult patients received the questionnaire and 3126 responded (46.1%. Statistically significant differences were found with respect to health status (higher percentage of chronic and severe conditions in the homeopathic group, perception of side effects (higher percentage of reported side effects in the conventional group and patient satisfaction (higher percentage of satisfied patients in the homeopathic group. Conclusion Overall patient satisfaction was significantly higher in homeopathic than in conventional care. Homeopathic treatments were perceived as a low-risk therapy with two to three times fewer side effects than conventional care

    Medical charts of 480 schizophrenic in-patients (581 treatments) were analysed to evaluate the efficacy and side-effects of clozapine. Clozapine treatment lasted for mean 49 (s.d. 38) days. Of the sample, 11.0% showed worsening or no change, 31.5% slight improvement, 53.0% marked improvement and 4.5% almost total reduction of symptoms. At least one major side-effect occurred in 68.0% of patients. A combination of clozapine with classical neuroleptics, antidepressants, benzodiazepines or lithium is tolerated by most patients, but increases the incidence of some side-effects. Clozapine treatment had to be discontinued because of severe side-effects in 8.6% of patients. In 81 schizophrenic out-patients, clozapine significantly reduced the days of in-patient treatment and number of hospital readmissions. Two patients developed leucopenia but had no complications after clozapine withdrawal. This study indicates a satisfactory benefit/risk ratio and compliance in most of the patients.

    Tattoo removal by laser therapy is a frequently performed procedure in dermatological practices. Quality-switched ruby, alexandrite, or Nd:YAG lasers are the most suitable treatment devices. Although these techniques are regarded as safe, both temporary and permanent side effects might occur. Little has been published on the frequency of complications associated with laser tattoo removal. We performed an Internet survey in German-speaking countries on characteristics of laser tattoo removal and associated side effects. A total number of 157 questionnaires entered the final analysis. Motivations for laser tattoo removal were mainly considering the tattoo as youthful folly (29%), esthetic reasons (28%), and 6% indicated medical problems. One third of participants were unsatisfied with the result of laser tattoo removal, and a complete removal of the tattoo pigment was obtained in 38% only. Local transient side effects occurred in nearly all participants, but an important rate of slightly visible scars (24%) or even important scarring (8%) was reported. Every fourth participant described mild or intense tan when the laser treatment was performed, and the same number of people indicated UV exposure following laser therapy, which should normally be avoided in these circumstances. As reported in the literature, nearly half of the participants experienced hypopigmentation in the treated area. Our results show that from the patients' point of view there is an important rate of side effects occurring after laser tattoo removal. Appropriate pretreatment counseling with regard to realistic expectations, possible side effects, and the application of test spots is mandatory to ensure patient satisfaction. Laser treatment should be performed by appropriately trained personnel only.

  4. Side effects related to potentially inappropriate medications in elderly psychiatric patients under everyday pharmacotherapy.

    Potentially inappropriate medication (PIM) is suggested to give rise to adverse drug events. To study this suggestion for elderly psychiatric patients, an observational analysis related prescription of PRISCUS PIMs and drug-induced side effects in old aged (≥65 years) psychiatric inpatients and outpatients under conditions of everyday pharmacotherapy. Request forms from a therapeutic drug monitoring (TDM) survey and medical files were screened for medication to identify PIMs of the PRISCUS list and assessed using the Udvalg for Kliniske Undersøgelser (UKU) side effect rating scale. From 914 TDM request forms, data were available for 168 patients (64.3 % female). Patients (mean ± SD age 73.0 ± 5.5 years) received by mean 6.4 ± 3.9 drugs per day. More than half of them (53.0 %, n = 89) had at least one PIM, inpatients 0.9 ± 0.8 and outpatients 0.5 ± 0.7. Predominant PIMs were hypnotic drugs (69 %) in inpatients and antipsychotic drugs (35.6 %) in outpatients. The number of PIMs correlated with the total number of drugs administered per day (Spearman correlation coefficient 0.225, p  0.05) with number of PIMs. However, only 6 of 77 patients who took no PRISCUS PIMs but 2 of 3 patients who took 3 PRISCUS PIMs exhibited severe side effects. Though the prevalence for PIMs and side effects was high in old aged psychiatric inpatients and outpatients, PIMs could not be identified as major determinants of overall unwanted side effects. Nevertheless, prescription of PIMs should be minimized, especially of hypnotic drugs, to improve safety.

  5. R-ketamine: a rapid-onset and sustained antidepressant without psychotomimetic side effects

    Although the efficacy of racemate ketamine, a rapid onset and sustained antidepressant, for patients with treatment-resistant depression was a serendipitous finding, clinical use of ketamine is limited, due to psychotomimetic side effects and abuse liability. Behavioral and side-effect evaluation tests were applied to compare the two stereoisomers of ketamine. To elucidate their potential therapeutic mechanisms, we examined the effects of these stereoisomers on brain-derived neurotrophic factor (BDNF)–TrkB signaling, and synaptogenesis in selected brain regions. In the social defeat stress and learned helplessness models of depression, R-ketamine showed a greater potency and longer-lasting antidepressant effect than S-ketamine (esketamine). Furthermore, R-ketamine induced a more potent beneficial effect on decreased dendritic spine density, BDNF–TrkB signaling and synaptogenesis in the prefrontal cortex (PFC), CA3 and dentate gyrus (DG) of the hippocampus from depressed mice compared with S-ketamine. However, neither stereoisomer affected these alterations in the nucleus accumbens of depressed mice. In behavioral tests for side effects, S-ketamine, but not R-ketamine, precipitated behavioral abnormalities, such as hyperlocomotion, prepulse inhibition deficits and rewarding effects. In addition, a single dose of S-ketamine, but not R-ketamine, caused a loss of parvalbumin (PV)-positive cells in the prelimbic region of the medial PFC and DG. These findings suggest that, unlike S-ketamine, R-ketamine can elicit a sustained antidepressant effect, mediated by increased BDNF–TrkB signaling and synaptogenesis in the PFC, DG and CA3. R-ketamine appears to be a potent, long-lasting and safe antidepressant, relative to S-ketamine, as R-ketamine appears to be free of psychotomimetic side effects and abuse liability. PMID:26327690

    2008-03-01

    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.

    Full Text Available Accumulating evidence suggests that Japanese herbal medicines, called Kampo, have beneficial effects on cancer chemotherapy-induced side effects. Rikkunshito ameliorates cisplatin-induced anorexia through an antagonistic effect on the 5-HT receptors and by increasing the serum ghrelin levels. Hangeshashinto improves irinotecan-induced diarrhea and chemotherapy-induced mucositis by inhibiting the activity of β-glucuronidase as well as the synthesis of prostaglandin E2. Goshajinkigan prevents oxaliplatin-induced neurotoxicity, possibly through suppressing functional alterations of the transient receptor potential (TRP channels. In this review, we will summarize the currently available literature regarding the clinical efficacy and potential mechanisms of Kampo medicines in the treatment of cancer chemotherapy-induced side effects.

    The novel immunomodulatory drugs lenalidomide and thalidomide and the novel proteasome inhibitor bortezomib can cause gastrointestinal side effects, including constipation, diarrhea, nausea, and vomiting, which can have a deleterious effect on quality of life and interfere with optimal therapy. The International Myeloma Foundation's Nurse Leadership Board developed this consensus statement for the management of gastrointestinal side effects associated with novel therapies to be used by healthcare providers in any medical setting. It includes grading criteria and general recommendations for assessing and managing the side effects. Although constipation, diarrhea, nausea, and vomiting are expected side effects associated with novel therapies for multiple myeloma, they are manageable with appropriate medical interventions.

    Full Text Available Schizotypy is regarded as a trait vulnerability for psychotic disorders, yet alone is insufficient for development of a diagnosable disorder. Additional symptoms and psychological distress are necessary for help seeking and transition from an at risk mental state to a clinical diagnosis. The present study investigated the interaction between trait schizotypy, state auditory verbal hallucination (AVH predisposition, distress and handedness for the expression of neurological soft signs (NSS, a neurodevelopmental vulnerability factor for psychosis. Cluster analysis formed schizotypy groups statistically across the dimensions captured by the SPQ. It was hypothesized that schizotypy and AVH predisposition would interact, resulting in significantly greater NSS. Psychological distress and handedness were hypothesized to be significant covariates, accounting for some variance in the expression of NSS between the groups. A sample of University students (n = 327 completed the Schizotypal Personality Questionnaire, Launay-Slade Hallucination Scale, General Health Questionnaire and the Neurological Evaluation Scale (NES. Cluster Analysis revealed four schizotypy groups. Distress was not a significant covariate in any analysis. As expected, those with high overall schizotypy and high AVH predisposition expressed significantly greater Motor-Coordination NSS compared to those with high schizotypy and low AVH predisposition. Within the Mixed Interpersonal and Cognitive-Perceptual Schizotypy cluster, those with low AVH predisposition expressed significantly more Motor-Coordination NSS than those with high AVH predisposition. These findings suggest motor coordination NSS are detectable in schizotypy, and AVH predisposition appears to interact with these traits. This study highlights the importance of considering both trait and subclinical state risk factors when investigating risk for psychosis.

    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.

    Boron nitride quantum dots (BNQDs) functionalized with chemical ligands exhibit intriguing optoelectronic properties due to the quantum confinement effect. This paper presents peculiar insights on the effect of side defects on the electronic structure and optical properties of BNQDs functionalized with different chemical bonds including hydrogen (H), nitrogen (N), hydroxyl (OH), amine (NH2), and thiol groups (inspired by experimental reports of functionalized BN nanosheets and nanotubes) Weng et al., Chem. Soc. Rev. 45, 3989 (2016), 10.1039/C5CS00869G. Hybrid density functional simulations and Green's function calculations indicate an intriguing coexistence of two different Peierls-like distortions in the functionalized low-dimensional material. The presence of side defects increases the side strain and creates interband electronic states. As a result, the band gap of BNQDs could vary in a wide range depending on the type of chemical bonds and surface disorders. Enhanced edge states also improve the photoluminescence emission of the quantum dots. These side-defect enriched states in BNQDs create optical and electrical responses which could offer unprecedented potential for large scale nanophotonics such as photovoltaic, bioimaging, and quantum communication.

    Over the last years there has been a substantial growth in research related to specific training methods in soccer with a strong emphasis on the effects of small-sided games. The increase of research in this topic is coincident with the increase of popularity obtained by specific soccer conditioning, which involves training players to deal with soccer match situations. Given the limited time available for fitness training in soccer, the effectiveness of small-sided games as a conditioning stimulus needs to be optimized to allow players to compete at the highest level. Available studies indicate that physiological responses (e.g. heart rate, blood lactate concentration and rating of perceived exertion), tactical and technical skill requirements can be modified during small-sided games by altering factors such as the number of players, the size of the pitch, the rules of the game, and coach encouragement. However, because of the lack of consistency in small-sided games design, player fitness, age, ability, level of coach encouragement, and playing rules in each of these studies, it is difficult to make accurate conclusions on the influence of each of these factors separately.

    Motor and cognitive symptoms are frequent in persons with neurological disorders and often require extensive long-term rehabilitation. Recently, a variety of music-based interventions have been introduced into neurological rehabilitation as training tools. This review aims to 1) describe and define music-based intervention modalities and content which are applied in experimental studies; and 2) describe the effects of these interventions on motor and/or cognitive symptoms in the neurological population. The databases PubMed and Web of Science were searched. Cited references of included articles where screened for potential inclusion. A systematic literature search up to 20th of June 2016 was conducted to include controlled trials and cohort studies that have used music-based interventions for ≥3 weeks in the neurological population (in- and outpatients) targeting motor and/or cognitive symptoms. No limitations to publication date was set. EVIDENCE SYNTHESISː Nineteen articles comprising thirteen randomized controlled trials (total participants Nexp=241, Nctrl=269), four controlled trials (Nexp=59, Nctrl=53) and two cohort studies (N.=27) were included. Fourteen studies were conducted in stroke, three in Parkinson's disease, and two in multiple sclerosis population. Modalities of music-based interventions were clustered into four groups: instrument-based, listening-based, rhythm-based, and multicomponent-based music interventions. Overall, studies consistently showed that music-based interventions had similar or larger effects than conventional rehabilitation on upper limb function (N.=16; fine motricity, hand and arm capacity, finger and hand tapping velocity/variability), mobility (N.=7; gait parameters), and cognition (N.=4; verbal memory and focused attention). CONCLUSIONSː Variety of modalities using music-based interventions has been identified and grouped into four clusters. Effects of interventions demonstrate an improvement in the domains assessed

    has an advantage over the combined oral contraceptive pill, and provides a simple, effective alternative for women who cannot use the pill for these reasons. Similarly, it has been suggested that women who suffer from focal migraine and are therefore advised against use of the combined oral contraceptive pill can still use progestogen-only contraceptives. Although the POP is medically safe in these circumstances, in young women it is less effective, and involves strict time keeping, which will be disadvantageous for some women. Side effects, long term use and schedules of administration are also discussed. The use of local protocols to allow nurse administration is to be supported both in general practice and the clinic situation. Perhaps the most important issue surrounding the use of DMPA is that of patient information. The method has had a particularly bad public image, which naturally makes potential users anxious and subject to misinformation from poorly informed or biased sources. Also, it is temporarily irreversible during its three months duration, so the duration of any problems or anxieties resulting from side effects may be longer than for other methods. It is of paramount importance that easily understood, accurate patient information leaflets are available, since biased and inaccurate information is readily available from women's magazines, perpetuating the myths surrounding the method.

      Ziconotide is a reversible blocker of the N-type neuronal voltage-sensitive calcium channels with analgesic effects. The main adverse effects of ziconotide are ataxia, dizziness, gait disorder, confusion, hallucinations, and gastrointestinal symptoms.   Eighteen chronic pain patients with intrathecal ziconotide treatment were investigated using the Mini International Neuropsychiatric Interview for psychiatric disorders according to the DSM IV.   Ten patients showed good pain relief (ΔVAS ≥ 50%) after one year of treatment. Patients without psychiatric comorbidity exhibited better outcomes, without autonomic side-effects. Eight patients with panic disorder (always comorbid with other psychiatric disorders) showed the greatest number of side-effects during treatment with ziconotide.   Emotional and cognitive symptoms of panic disorder are associated with autonomic symptoms resulting from parasympathetic activation. Dysfunction of both cholinergic and N-type calcium channel activity was found.   A psychiatric disorder with cholinergic-noradrenergic system impairment could increase some side-effects of treatment with N-type calcium channel blockers. © 2011 International Neuromodulation Society.

    Full Text Available Background. Mosquito-borne diseases constitute an important cause of morbidity and mortality. The use of personal protective measures (PPM like mats, bednets, screening, repellents, liquid vaporizers, mosquito coils, and so forth has been advocated as an effective tool in control of mosquito-borne diseases, but data about the safety profile of personal protective measures is still scarce. Objective. To study the usage and side effects of personal protective measures against mosquitoes among current users in Delhi. Materials and Methods. A community-based cross-sectional study among 350 adult individuals selected by systematic sampling method. Data was collected using pretested semistructured questionnaire after taking written informed consent. Data was analysed using SPSS version 17. Chi-square/Fisher’s Exact test was used for qualitative variables to find association and P value <0.05 was considered significant. Results. Out of 350 families selected, 210 belonged to rural area and 140 to urban area. Personal protective measures were used by 219 (62.5% subjects. Liquid vaporizer was the most preferred method (41.4%. Most common perceived side effect of personal protective measures was headache (7.7%. Other perceived side effects were cough (3.2%, sore throat (2.7%, allergy (1.3%, and eye irritation (0.9% predominantly among coil users. Conclusion. There is a need to have a close watch for side effects of personal protective measures among users. Further research is also needed to develop safe and effective personal protective measures against mosquitoes.

  19. The effect of probiotics supplementation on Helicobacter pylori eradication rates and side effects during eradication therapy: a meta-analysis.

    Full Text Available BACKGROUND: Previous meta-analyses reported that probiotics improve the effectiveness of Helicobacter pylori (H. pylori eradication during antibiotic therapy, while results regarding a possible reduction of side effects remained inconclusive. Moreover, the effectiveness of different strains of probiotics has not been studied so far. It is further conceivable that probiotics will produce additional effects only if antibiotics are relatively ineffective. METHODS: This meta-analysis includes eligible randomized controlled trials examining effects of probiotics supplementation on eradication rates (ER and side effects, published up to May 2014. Sub-group analysis was performed to compare different probiotic strains and antibiotic therapies with different effectiveness in controls (ER 80%. Publication bias was assessed with funnel plots and Harbord's test. The quality of the trials was assessed with the Cochrane risk of bias tool. RESULTS: Thirty-three RCTs involving a total of 4459 patients met the inclusion criteria in case of eradication rates of which 20 assessed total side effects in addition. Overall, the pooled eradication rate in probiotics supplementation groups was significantly higher than in controls (ITT analysis: RR 1.122, 95% CI 1.086-1.159, PP analysis: RR 1.114, 95% CI 1.070-1.159. Sub group-analysis could, however, confirm this finding only for four individual strains (Lactobacillus acidophilus, Lactobacillus casei DN-114001, Lactobacillus gasseri, and Bifidobacterium infantis 2036 and for relatively ineffective antibiotic therapies. There was a significant difference between groups in the overall incidence of side effects (RR 0.735, 95% CI 0.598-0.902. This result was, however, only confirmed for non-blinded trials. CONCLUSIONS: The pooled data suggest that supplementation with specific strains of probiotics compared with eradication therapy may be considered an option for increasing eradication rates, particularly when antibiotic

    Electroacupuncture effect on neurological behavior and the expression of tyrosine kinase Janus kinase 2 (JAK 2) of ischemic cortex in rats with the focal cerebral ischemia were investigated in this study. The model of focal cerebral ischemia was established by the heat-coagulation induced the occlusion of the middle cerebral artery. The electro-acupuncture was applied on Baihui (GV 20) and Dazhui (GV 14), and AG490 was applied by intracerebroventricular infusion. The expressions of JAK2 mRNA and phospharylated JAK2 (p-JAK2) in the ischemic cortex were observed by in situ hybridization and western blotting. The expressions of JAK2 mRNA and p-JAK2 were rarely found in sham surgery group. In model group, the expression of JAK2 mRNA and JAK2 phosphorylation had increased. After 1 day of cerebral ischemia, the expression had reached its peak. After cerebral ischemia, the expressions of JAK2 mRNA and p-JAK2 were consistent with the neurological deficit score. Electroacupuncture treatment and AG490 intervention were able to improve the neurological deficit score after cerebral ischemia, and down-regulate the expressions of JAK2 mRNA and JAK2 phosphorylation. After cerebral ischemia, the excessive expressions of JAK2 and the JAK2 phosphorylation would be one of mechanisms by which the brain injury got worse. The therapy of electro-acupuncture could reduce the expression of JAK2, and inhibit JAK2 phosphorylated activation, so as to block the abnormal activation of signal transduction pathway which was induced by JAK2.

    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.

    Neonatal intubation is stressful and should be performed with premedication. In the case of an INSURE (intubation/surfactant/extubation) procedure a short duration of action of the premedication used is needed to facilitate fast extubation. Given its pharmacological profile, remifentanil seems a suitable candidate. The aim here was to evaluate the effect and side effects of remifentanil as a premedication for preterm neonates undergoing INSURE. A prospective, single-center study in a level III neonatal intensive care unit was conducted. The quality of sedation was assessed in preterm infants receiving remifentanil prior to intubation for the INSURE procedure. Intravenous remifentanil was administered quickly and followed by a saline flush in approximately 30 s. The quality of sedation was defined by a combination of adequate sedation score, good intubation conditions and absence of side effects. The study was terminated after the inclusion of 14 patients because of the high rate of side effects and the poor intubation conditions. Adequate sedation was achieved in only 2 patients (14%). Six patients (43%) needed additional propofol to obtain adequate sedation. Chest wall rigidity occurred in 6 patients (43%). The rapid administration of remifentanil provides insufficient sedation and is associated with a high risk of chest wall rigidity in preterm neonates. © 2016 S. Karger AG, Basel.

    Unwanted hairs are a common problem in which different light sources were developed as the treatment of choice. Alexandrite laser, diode laser, and intense pulsed light (IPL) were clinically used for this purpose with long-term scarce comparative results. The objective of the study was to compare the clinical efficacy, complications, and long-term hair reduction of alexandrite laser, diode laser, and IPL. Clinical trials on 232 persons using diode, alexandrite, laser and IPL were conducted. The number of sessions to reach optimal result varied between 3 and 7. Then the side effects were evaluated. Six months after the last session, optimal hair reduction was observed with no significant differences between the light sources, but a hair reduction was found to be higher using the diode laser. Side effects were observed with all light sources but more frequently with diode. Our findings indicate that all three light sources tested have similar effects on hair removal and in Iranian patients, using lower wavelengths minimizes the side effects.

    The objective of this study is to evaluate the side effects of intracavernous vasoactive agents on clinical and sonographic basis. Two groups of patients were included, group I included 168 ED patients trained on self-injection therapy using one of the three protocols. Protocol A: papaverine; protocol B: PGE1; and protocol C: trimix (papaverine, phentolamine and PGE1). Patients were followed up clinically, sonographically and by laboratory investigations for 6 months to evaluate the occurrence of side effects. Group II included 21 patients presenting to our department for the first time with a complication of intracavernous injection pharmacotherapy (ICI) initiated elsewhere. In all, 168 patients of group I completed the study. Patients on papaverine had the highest incidence of complications concerning prolonged erection, subcutaneous hematoma and penile fibrosis. Postinjection penile pain was observed more with groups B and C than group A. No systemic side effects were reported. Duplex ultrasound was beneficial in detecting mild clinically impalpable fibrosis. In total, 10 patients of group II presented with prolonged erection, seven with penile fibrosis, three with cavernositis and one with intracavernous needle breakage. We conclude that although ICI therapy is an effective second-line treatment option, patients on a self-injection program should be followed up both clinically and sonographically both at the initiation phase and on regular follow-up visits.

    To determine the efficacy of peer-assisted clinical skills training for students during their neurology clerkship. Students (n = 122) were randomized to get clinical skills training from either student (peer) instructors (experimental group) or from experienced clinical staff (control group). The remaining schedule during the clerkship did not differ between both groups. Primary endpoint was students' practical skills and knowledge tested at the end of the course by a written test and objective structured clinical examination (OSCE). Secondary endpoints were evaluation of the practical training and self-estimated gain in theoretical and practical competence. In the written test, the peer-trained group (n = 66) scored 69.5 +/- 10.2 (95% CI 67-72) points of 100 and the postgraduates-trained group (n = 56) 66.7 +/- 11.4 (95% CI 63.6-69.8) (P = 0.15). In the OSCE the peer-trained group scored 93.7 +/- 6.3 (95% CI 92.1 to 95.2) points of 100 and the postgraduates-trained group 92 +/- 5.1 (95% CI 90.6 to 93.4) (P = 0.11). In the evaluation and self-assessment items, there was no significant difference between the two groups except for the postgraduates' higher competence (P = 0.004). Peer-trained students pass written exam and OSCE as efficient as postgraduates-trained students. Self-assessed learning success is equally rated in both groups.

    Mechanistic target of rapamycin inhibitors reduce loss of lung function in lymphangioleiomyomatosis (LAM), although their benefit varies between individuals. We examined lung function response and side effects to rapamycin in a national cohort. Subjects were receiving rapamycin for progressive lung disease. Clinical evaluation, detailed phenotyping, serial lung function, rapamycin and safety monitoring were performed according to a clinical protocol. Lung function change, measured as FEV1 slope (ΔFEV1), was reported for those treated for 1 year or longer. Rapamycin was associated with improved ΔFEV1 in 21 individuals where pretreatment data were available (p<0.0001). In 47 treated for a mean duration of 35.8 months, mean ΔFEV1 was +11 (SD 75) mL/year, although it varied from +254 to -148 mL/year. The quartile with the highest positive ΔFEV1 had greater pretreatment FEV1 (p=0.02) and shorter disease durations (p=0.02) than the lowest quartile. Serum rapamycin level was positively associated with side effects (p=0.02) but not ΔFEV1 over 1 year. Within the first month of therapy, apthous ulcers, nausea and diarrhoea were associated with higher rapamycin levels. Acne, oedema and menstrual irregularities tended to increase over the first year of therapy. At the end of observation, the prevalence of side effects was 5% or less. Rapamycin reduces lung function loss in LAM, although in some, ΔFEV1 continues to fall at an accelerated rate. Poor response to rapamycin was associated with lower pretreatment lung function and longer disease duration but not serum level. Early intervention with low-dose rapamycin may preserve lung function and reduce side effects. © Article author(s) (or their employer(s) unless otherwise stated in the text of the article) 2017.

    Neuroleptics, antidepressants, lithium, anxiolytics, and hypnotics may be excreted in breast milk. Because of the danger to the neonate, drugs such as diazepam, lithium, bromides, reserpine, and opium alkaloids should not be given to lactating women, and barbiturates, haloperidol, and penfluridol should be administered with caution. The side effects produced as a result of breast-feeding of the infant by mothers consuming psychotropic drugs are reviewed and possible preventive measures are discussed.

  12. [The allergic and other side effects of non-steroid antiinflammatory drugs and gold salts].

    2004-09-19

    The wider usage of non steroid antiinflammatory drugs (NSAIDs) raises the significance of their side effects. The discovery of the two different cyclo-oxygenases (COX 1 and COX-2) led to the incorporation of more selective enzyme inhibitors into the therapeutic tools against disorders with pain and inflammation, in order to minimize the frequency of the side effects. Selective COX-2 inhibitors are well tolerated by most of the patients with a history of sensitivity against classical NSAIDs. The well-known gastrointestinal side effects (ulcers, bleedings) are much less frequent in the case of selective COX-2 inhibitors in comparison with non-selective COX inhibitors. However, the lack of "healing" prostaglandins as an effect of COX-2 antagonism may prevent the improvement of existing ulcers. In addition almost all other organs have been found to be affected in COX-2 knockout mice (COX-2 paradoxon). Hepatotoxicity is usually rare, its reason is most probably idiosyncrasy. Persistent nephropathy can be worsened by the inhibition of COX-2, however normal renal functions have not been changed in humans using selective COX-2 inhibitors. Authors' registry consists of 1000 patients with a history of suspected drug-allergy, during a 15 years' period. Approximately 30% of the cases have been connected with NSAIDs and with antirheumatic drugs. Because of functional similarities gold salts, proved suitable for the treatment of juvenile rheumatoid arthritis (JRA) and of osteoarthritis (OA) were included as well. Besides rheumatologic applications the second most common indication for these drugs was pain and/or fever. Among cutaneous symptoms intolerance was present at a relatively low frequency--as salicylates had not been taken into consideration. Next to salicylates the most frequent side effects were caused by pyrazolon derivates. Urticaria and angioedema were the most frequently observed symptoms on the skin--our observations are in accordance with other publications. Non

    The objective of this study was to investigate side airbag (SAB) deployment in near side crashes and compare injuries and contact points between occupants with and without SAB deployment. Using NASS 2000-2008 and selecting for near side cases, with PDOF ± 20 degrees from 90 or 270, for non-pregnant adult belted occupants, there were 20,253 (weighted) SAB deployments. NASS showed that SABs have been increasing within the fleet, comprising 2% of airbags in 2000 and increasing to 33% of airbags in 2008. To investigate deployed SABs, we developed a three-step methology to pair CIREN cases to study the effects of deployment on occupant outcome. The first step involved extracting near side impacts from CIREN with adult, non-pregnant occupants seated in row 1 (drivers or right front passengers). In the second step, each case was quantitatively compared to FMVSS 214 barrier test standards using a 6 point similarity scoring system. Cases scoring at least 3 points were then qualitatively analyzed and 33 pairs of cases of the same vehicle make/model but opposite SAB status were chosen. Occupants with deployed SAB had reduced occurrences and severity of head and face, neck and cervical spine, and thoracic injuries and fewer injurious contacts to side components including the door, a-pillar, and window sill. SAB deployment was statistically significant for reducing occupant MAIS and ISS and thorax airbags were statistically significant for reducing thoracic and neck/cervical spine injury severity. The average ISS with SAB deployment was 21, while the average ISS of those without was 33. This study establishes methods for performing comparisons between CIREN cases based on regulatory conditions and shows injury reduction in key body regions with SAB deployment.

    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.

    Full Text Available Tumor necrosis factor-alpha antagonism is an important treatment strategy in patients with rheumatoid arthritis, psoriatic arthritis, vasculitis, and ankylosing spondylitis. Adalimumab is one of the well-known tumor necrosis factor-alpha blocking agents. There are several side effects reported in patients with adalimumab therapy. Cardiac side effects of adalimumab are rare. Only a few cardiac side effects were reported. A 61-year-old man treated with adalimumab for the last 6 months due to psoriatic arthritis presented with typically acute pleuropericarditis. Chest X-ray and echocardiography demonstrated marked pericardial effusion. Patient was successfully evaluated for the etiology of acute pleuro-pericarditis. Every etiology was excluded except the usage of adalimumab. Adalimumab was discontinued, and patient was treated with 1200 mg of ibuprofen daily. Control chest X-ray and echocardiography after three weeks demonstrated complete resolution of both pleural and pericardial effusions. This case clearly demonstrated the acute onset of pericarditis with adalimumab usage. Acute pericarditis and pericardial effusion should be kept in mind in patients with adalimumab treatment.

    In order to evaluate the potential for refractive surgery, fs laser pulses of 150-fs pulse duration were used to process corneal tissue of dead and living animal eyes. By focusing the laser radiation down to spot sizes of several microns, very precise cuts could be achieved inside the treated cornea, accompanied with minimum collateral damage to the tissue by thermal or mechanical effects. During histo-pathological analysis by light and transmission electron microscopy considerable side effects of fs photodisruption were found. Due to the high intensities at the focal region several nonlinear effects occurred. Self-focusing, photodissociation, UV-light production were observed, leading to streak formation inside the cornea.

    Full Text Available Treatment of developmental disorders, correction of learning disabilities and behavioral problems in children should be prompt, complex and include pharmacotherapy with nootropic agents. The results of recent studies shown in this review proved effectiveness of pharmacotherapy with pyritinol in children with perinatal injury of central nervous system and its consequences, psychomotor and speech development delay, dyslexia, attention deficit/hyperactivity disorder, cognitive disorders and learning disabilities (including manifestations of epilepsy, chronic tic disorders and Tourette syndrome. Due to its ability to optimize metabolic processes in central nervous system, pyritinol is used in treatment of vegetative dysfunction in children and adolescents, especially associated with asthenical manifestations, as well as in complex therapy of exertion headache and migraine. The drug is effective in treatment of cognitive disorders in children and adolescents with epilepsy, pyritinol was administered without changing of the basic anticonvulsive therapy and no deterioration (increase of severity of seizures or intensity of epileptiform activity on electroencephalogramms was observed. Significant nootropic effect of pyritinol, including neurometabolic, neuroprotective, neurodynamic and other mechanisms, in association with safety and rare side effects of this drug determines its wide usage in pediatric neurology.

    This study attempts to elucidate the relationship between neurological effects and mercury/methylmercury concentrations in various biomarkers, including meconium, hair, fingernail, and toenail. Eight-three mother-infant pairs were recruited between August 2008 and December 2009, and follow-up examinations on these children were completed after three years. The Bayley Scales of Infant and Toddler Development (Bayley-III) for evaluating the cognitive, language, and motor development of three-year-old children were calculated and validated. The geometric mean of the total mercury concentration in meconium was 89.6 ng g(-1). The methylmercury concentrations in hair, fingernail, and toenail samples were 1.96, 0.64, and 0.55 μg g(-1), respectively. Seventy percent of children had hair methylmercury concentrations exceeding the U.S. environmental protection agency (EPA) reference of 1 μg g(-1). A significantly positive correlation was obtained between methylmercury levels in hair, fingernail, and toenail. These methylmercury levels were also significantly positively correlated with the children's fish intake and negatively correlated with a Bayley-III scale score of expressive language. The prenatal mercury exposure, however, did not show significant influence on neurological development. High fish consumption appears to be a critical risk factor for methylmercury levels in children and may cause a lower expressive language score. Copyright © 2014 Elsevier Ltd. All rights reserved.

    Full Text Available Children with epilepsy have a high rate of mood and behavior problems yet few studies consider the emotional and behavioral impact of surgery. No study to date has been sufficiently powered to investigate effects of both side (left/right and site (temporal/frontal of surgery. One hundred patients (aged 6-16 and their families completed measures of depression, anxiety and behavioral function as part of neuropsychological evaluations before and after surgery for pharmacoresistant epilepsy. Among children who had left-sided surgeries (frontal=16; temporal=38, there were significant interactions between time (pre to postoperative neuropsychological assessment and resection site (frontal/temporal on Anhedonia, Social Anxiety, and Withdrawn/Depressed scales. Patients with frontal lobe epilepsy (FLE endorsed greater presurgical anhedonia and social anxiety than patients with temporal lobe epilepsy (TLE, with scores normalizing following surgery. While scores on the Withdrawn/Depressed scale were similar between groups before surgery, the FLE group showed greater symptom improvement after surgery. In children who underwent right-sided surgeries (FLE=20; TLE=26 main effects of time (patients in both groups improved and resection site (caregivers of FLE patients endorsed greater symptoms than those with TLE were observed primarily on behavior scales. Individual data revealed that a greater proportion of children with left FLE demonstrated clinically significant improvements in Anhedonia, Social Anxiety, and Aggressive Behavior than children with TLE. This is the first study to demonstrate differential effects of both side and site of surgery in children with epilepsy at group and individual levels. Results suggest that children with FLE have greater emotional and behavioral dysfunction before surgery, but show marked improvement after surgery. Overall, most children had good emotional and behavioral outcomes, with most scores remaining stable or improving.

    Full Text Available Young stroke patients have a strong desire to return to the society, but few studies have been conducted on their rehabilitation training items, intensity, and prognosis. We analyzed clinical data of young and middle-aged/older stroke patients hospitalized in the Department of Neurological Rehabilitation, China Rehabilitation Research Center, Capital Medical University, China from February 2014 to May 2015. Results demonstrated that hemorrhagic stroke (59.6% was the primary stroke type found in the young group, while ischemic stroke (60.0% was the main type detected in the middle-aged/older group. Compared with older stroke patients, education level and incidence of hyperhomocysteinemia were higher in younger stroke patients, whereas, incidences of hypertension, diabetes, and heart disease were lower. The average length of hospital stay was longer in the young group than in the middle-aged/older group. The main risk factors observed in the young stroke patients were hypertension, drinking, smoking, hyperlipidemia, hyperhomocysteinemia, diabetes, previous history of stroke, and heart disease. The most accepted rehabilitation program consisted of physiotherapy, occupational therapy, speech therapy, acupuncture and moxibustion. Average rehabilitation training time was 2.5 hours/day. Barthel Index and modified Rankin Scale scores were increased at discharge. Six months after discharge, the degree of occupational and economic satisfaction declined, and there were no changes in family life satisfaction. The degrees of other life satisfaction (such as friendship improved. The degree of disability and functional status improved significantly in young stroke patients after professional rehabilitation, but the number of patients who returned to society within 6 months after stroke was still small.

  4. Tumor parameters predict the risk of side effects after ruthenium-106 plaque brachytherapy of uveal melanomas.

    Lisa Tarmann

    Full Text Available To report on radiation-related side effects and complications after ruthenium-106 plaque brachytherapy of uveal melanomas.Medical records of 143 eyes with uveal melanoma, treated by ruthenium-106 brachytherapy between 1997 and 2012 at a single center, were analyzed. We evaluated the occurrence of radiation-related side effects on the anterior and posterior segment of the eye. The influence of patient, tumor and treatment parameters on outcome was analyzed by multivariate time to event analysis considering competing risks.The median overall follow-up was 37.9 months. After treatment, the estimated risk at 12, 24 and 48 months for developing anterior segment complications was 25.3%, 37.5% and 50.3% for cataract formation and 5.4%, 6.4% and 8.1% for secondary glaucoma, respectively. The estimated risk for the occurrence of posterior segment complications 12, 24 and 48 months after treatment was 3.1%, 6.7% and 18.3% for radiation retinopathy, 18.3%, 27.1% and 42.6% for radiation maculopathy and 16.5%, 21.0% and 32.8% for radiation neuropathy, respectively. The risk of an increase in retinal detachment after treatment was 14.7%, 14.7% and 17.4% at 12, 24 and 48 months, respectively. The risk of vitreous hemorrhage occurring after treatment was 6.2%, 8.1% and 12.7%, and the risk of tumor vasculopathy was 15.4%, 17.4% and 19.0%. Scleral necrosis was observed in one patient.Radiation-related side effects and complications are common among patients treated with ruthenium brachytherapy for uveal melanoma. However, the risk for those largely depends on individual tumor parameters. Before treatment, patients should be informed of their specific risks to develop various side effects. Patient information before treatment should cover not only general information about the treatment and possible complications and side effects but should also give details on the specific risks of the patient in her individual situation. This also includes elucidating the

    Hypothyroidism is a common endocrine disease in dogs. A variety of clinicopathologic abnormalities may be present; however, neurologic deficits are rare. In some instances, neurologic deficits may be the sole manifestation of hypothyroidism. Consequent ly, the diagnosis and management of the neurologic disorders associated with hypothyroidism can be challenging. This article describes several neurologic manifestations of primary hypothyroidism in dogs; discusses the pathophysiology of hypothyroidism-induced neurologic disorders affecting the peripheral and central nervous systems; and reviews the evidence for the neurologic effects of hypothyroidism.

  6. Effect of Side Wind on the Directional Stability and Aerodynamics of a Hybrid Buoyant Aircraft

    2016-01-01

    Full Text Available Directional stability characteristics explain the capabilities of a hybrid buoyant aircraft’s performance against the side wind, which induces flow separation that is chaotic in nature and may lead to oscillations of the aerodynamic surfaces. A numerical study is carried out to estimate the effect of side wind. The boundary conditions for the computational domain are set to velocity inlet and pressure outlet. Due to the incompressible flow at the cruise velocity, the density is taken to be constant. For these steady state simulations, the time is discretized in first order implicit and the SIMPLE scheme is employed for pressure velocity coupling alongwith k-ω SST model. Based on the results obtained so far, it is concluded that voluminous hybrid lifting fuselage is the major cause of directional.

    1998-07-01

    Full text of publication follows: starting from the assumptions of support theory, this project analyzed the extent to which the specification of potential side effects influences the perceived risk associated, with a particular medication. Respondents were presented with an instruction leaflet for a medication which indicated (a) the overall probability that a side effect will occur or (b) the probability of occurrence of several specific side effects. Support theory predicts that the cognitive availability of potential side effects and therefore the perceived risk increases as a function of the specificity with which the side effects are presented. In contrast the evaluation-mediation hypothesis predicts that a more detailed presentation of potential side effects enhances the perceived quality of the information leaflet and thereby leads to a reduction of perceived risk. Support for the evaluation-mediation hypothesis was found in a series of studies which included the editing hypothesis and the elaboration likelihood model as additional explanations: the more detailed the information about potential side effects, the lower the estimated risk of suffering a side effect on taking the medication. As predicted, the influence of presentation specificity on perceived risk was mediated almost exclusively by the perceived quality of the information leaflet. A current series of studies seeks to support the evaluation-mediation hypothesis in a completely different domain, the perceived risk of environmental pollution by motor vehicles. (author)

    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 3- D ray tracing code, to investigate these effects. Using a simulated ITER operating scenario, characteristics of the reflected RF waves returning to the launch plane are quantified as a function of a range of design parameters, including antenna height, antenna size, and antenna radial position. Results for edge/SOL measurement with both O- and X-modes using proposed antennas are reported.

    To study the possible effect of the side pinch on the steady-state current and the steady-state shock speed of a magnetically driven shock tube, a semiempirical model is formulated. The time history of the current, the radial and the translational motion of the current-carrying region are expressed...... show that the current-carrying region oscillates radially, but the current and the translational velocity of the current-carrying region approach the quasi-steady state rapidly. The deviation of the current from its “steady-state” value (when the pinch effect is absent) in no case amounts to more than...

    Full Text Available Knowledge on side effects of pesticides on non-target beneficial arthropods is a key point in Integrated Pest Management (IPM. Here we present the results of four experiments conducted in vineyards where the effects of chlorpyrifos, thiamethoxam, indoxacarb, flufenoxuron, and tebufenozide were evaluated on the generalist predatory mites Typhlodromus pyri Scheuten and Amblyseius andersoni (Chant, key biocontrol agents of herbivorous mites on grapevines. Results show that indoxacarb and tebufenozide had a low impact on the predatory mites considered here, while a significant impact was observed for chlorpyrifos, flufenoxuron, and thiamethoxam. The information obtained here should be considered in the design of IPM strategies on grapevine.

    To evaluate the consumption, prevalence, side effects and awareness of energy drinks among female university students in Saudi Arabia. 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 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. 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.

    Full Text Available Agricultural chemicals have been used extensively in modern agriculture and toxicological studies suggest a great potential for inducing undesirable effects on non target organisms. A model experiment was conducted in order to determine side effects of three nitrification inhibitors (NIs, 3,4dimethylpyrazolephosphate = DMPP, 4-Chlor-methylpyrazole phosphate = ClMPP and dicyandiamide = DCD on non target microbial processes in soils. Side effects and dose response curve of three NIs were quantified under laboratory conditions using silty clay, loam and a sandy soils. Dehydrogenase, dimethylsulfoxide reductase as well as nitrogenase activity (NA and potential denitrification capacity were measured as common and specific non target microbial processes. The influence of 5-1000 times the base concentration, dose response curves were examined, and no observable effect level = NOEL, as well as effective dose ED10 and ED50 (10% and 50% inhibition were calculated. The NOEL for microbial non target processes were about 30–70 times higher than base concentration in all investigated soils. The potential denitrification capacity revealed to be the most sensitive parameter. ClMPP exhibited the strongest influence on the non target microbial processes in the three soils. The NOEL, ED10 and ED50 values were higher in clay than in loamy or sandy soil. The NIs was the most effective in sandy soils.

    Although adverse neuropsychological and neurological health effects are well known among workers with high manganese (Mn) exposures in mining, ore-processing and ferroalloy production, the risks among welders with lower exposures are less well understood. Confined space welding in construction of a new span of the San Francisco-Oakland Bay Bridge without adequate protection was studied using a multidisciplinary method to identify the dose-effect relationship between adverse health effects and Mn in air or whole blood. Bridge welders (n = 43) with little or no personal protection equipment and exposed to a welding fume containing Mn, were administered neurological, neuropsychological, neurophysiological and pulmonary tests. Outcome variables were analysed in relation to whole blood Mn (MnB) and a Cumulative Exposure Index (CEI) based on Mn-air, duration and type of welding. Welders performed a mean of 16.5 months of welding on the bridge, were on average 43.8 years of age and had on average 12.6 years of education. The mean time weighted average of Mn-air ranged from 0.11-0.46 mg/m(3) (55% >0.20 mg/m(3)). MnB >10 microg/l was found in 43% of the workers, but the concentrations of Mn in urine, lead in blood and copper and iron in plasma were normal. Forced expiratory volume at 1s: forced vital capacity ratios (FEV(1)/FVC) were found to be abnormal in 33.3% of the welders after about 1.5 years of welding at the bridge. Mean scores of bradykinesia and Unified Parkinson Disease Rating Scale exceeded 4 and 6, respectively. Computer assisted tremor analysis system hand tremor and body sway tests, and University of Pennsylvania Smell Identification Test showed impairment in 38.5/61.5, 51.4 and 88% of the welders, respectively.

    Full Text Available Introduction: Electroencephalography (EEG is useful in seizure diagnosis. It needs cooperation and immobility of the person and if a child does not naturally sleep, pharmacological agents will be used to induce sleeping. The purpose of this study was to investigate efficacy and side effects of oral melatonin in sedation induction for EEG of children. Methods: In a quasi- experimental study, efficacy of single dose of 0.3mg/kg melatonin in achieving adequate sedation (Ramsay sedation score of four as well as its success in recording of EEG and its side effects in 40 children were investigated from September 2011 to March 2012. The participants aged 1-8 years who referred to EEG Unit of Shahid Sadoughi Hospital, Yazd, Iran and did not naturally sleep and immobilize. Results: Sixteen girls (40% and 24 boys(60% with mean age of 2.82 ±1.91 years were investigated. Adequate sedation and recording of EEG was achieved in 29 (72.5 % children. The drug was more effective in success of recording of EEG in less than two year old children (70.6% vs. 30.4% in two years old and more and pvalue= 0.04 as well as in those with developmental delay (93.3% vs. 60% in normal developmental status and pvalue =0.02. No serious side effects were seen in the patients. Conclusion: Melatonin is a safe and effective drug in sedation induction for EEG in children especially in those less than two years old and in children with developmental delay.

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

    New thiazolothiazole-dithienosilole copolymer semiconductors bearing side chains of different type, size, and topology were synthesized and used to demonstrate the influence of side chains on morphology, charge transport and photovoltaic properties. The field effect mobility of holes varied from 0.01-0.03 cm{sup 2}V{sup -1}s{sup -1} in PSOTT and PSEHTT to 0.12 cm{sup 2}V{sup -1}s{sup -1} in PSOxTT. The average power conversion efficiency of solar cells under 1.0 sun illumination could be varied from 2.1% in PSOxTT and 4.1% in PSOTT to 5.0% in PSEHTT. The highest photovoltaic efficiency achieved in PSEHTT, that has all-branched alkyl side chains and face-on {pi}-stacking orientation, was corroborated by its enhanced charge photogeneration observed by transient absorption spectroscopy.

    Full Text Available Afatinib is a second-generation epidermal growth factor receptor (EGFR inhibitor that has been shown to be effective against EGFR-mutated non-small cell lung cancer (NSCLC resistant to conventional EGFR inhibitors such as gefitinib and erlotinib. Although ocular side effects of gefitinib and erlotinib have been reported, those for afatinib have yet to be definitively established. This report presents details on the first case of unilateral iridocyclitis associated with the side effects of afatinib therapy. A 75-year-old Japanese male ex-smoker with EGFR-mutated NSCLC underwent afatinib therapy for multiple metastases. At 2 weeks, bilateral conjunctivitis developed. Topical medication and a 1-week afatinib washout period resulted in the improvement of the conjunctivitis. However, 3 days after the resumption of afatinib, the patient developed unilateral granulomatous anterior uveitis in his right eye. Best-corrected visual acuity (BCVA measurement indicated a decimal visual acuity of 0.2, while the slit-lamp findings were characterized by granulomatous inflammation, keratic precipitates, Koeppe nodules and posterior synechiae. There was no evidence suggesting other intraocular inflammatory disease or metastatic tumor. The left eye was intact. The use of topical medication including steroids and a washout of afatinib resulted in a gradual subsiding of the anterior uveitis. After resolution of the anterior uveitis, oral afatinib was resumed. BCVA of the right eye finally recovered to a decimal acuity of 1.0. Ophthalmologists should be aware of the possibility that side effects associated with afatinib could cause granulomatous anterior uveitis.

    This workshop addressed challenges of clinical research in neurosurgery. Randomized controlled clinical trials (RCTs) have high internal validity, but often insufficiently generalize to real-world practice. Observational studies are inclusive but often lack sufficient rigor. The workshop considered possible solutions, such as (1) statistical methods for demonstrating causality using observational data; (2) characteristics required of a registry supporting effectiveness research; (3) trial designs combining advantages of observational studies and RCTs; and (4) equipoise, an identified challenge for RCTs. In the future, advances in information technology potentially could lead to creation of a massive database where clinical data from all neurosurgeons are integrated and analyzed, ending the separation of clinical research and practice and leading to a new "science of practice."

    Although proverb tests are commonly used in the mental status examination surprisingly little is known about either normal comprehension or the interpretation of proverbial expressions. Current proverbs tests have conceptual and linguistic shortcomings, and few studies have been done to investigate the specific effects of neurological and psychiatric disorders on the interpretation of proverbs. Although frontal lobes have traditionally been impugned in patients who are "concrete", recent studies targeting deficient comprehension of non literal language (e.g. proverbs, idioms, speech formulas, and indirect requests) point to an important role of the right hemisphere (RH). Research describing responses of psychiatrically and neurologically classified groups to tests of proverb and idiom usage is needed to clarify details of aberrant processing of nonliteral meanings. Meanwhile, the proverb test, drawing on diverse cognitive skills, is a nonspecific but sensitive probe of mental status.

    Full Text Available Neurological disorders with a prolonged course, either remediable or otherwise are being seen increasingly in clinical practice and many such patients are young and are part of some organization or other wherein their services are needed if they were healthy and fit. The neurologists who are on the panel of these organizations are asked to certify whether these subjects are fit to work or how long they should be given leave. These certificates may be produced in the court of law and may be subjected to verification by another neurologist or a medical board. At present there are no standard guidelines in our country to effect such certification unlike in orthopedic specialty or in ophthalmology. The following is a beginning, based on which the neurologist can certify the neurological disability of such subjects and convey the same meaning to all neurologists across the country.

    An increase in enviromental pollution may lead to mercury toxicity of fish origin due to the accumulative nature of methylmercury in fish. The main sources of human exposure to organic mercury compounds are contaminated fish and other seafoods. This descriptive study was planned to determine mercury levels in anchovy and in hair samples from individuals with different fish consumption habits, and to evaluate those individuals in terms of toxic effects. For that purpose, we analyzed 100 anchovies from the Black Sea and 100 anchovies from the Sea of Marmara, and assessed 25 wholesale workers in fish markets and 25 cleaning firm employees from both Ankara and Istanbul. Mercury levels in samples were measured using a cold vapor atomic absorption spectrophotometer. Participants were examined neurologically and mini mental state examination was applied to evaluate their cognitive functions. Mercury levels in fish were found to be below the national and international permitted levels. There was no statistically significant relation between mercury levels and the sea from which fish were caught. Hair mercury levels for all participants were within permitted ranges. However, hair mercury levels in both cities increased significantly with amount and frequency of fish consumption. A significant correlation was determined at correlation analysis between levels of fish consumption and hair mercury levels in the fishmongers and in the entire group (r = 0.32, p = 0.025; r = 0.23, p = 0.023, respectively). Neurological examination results were normal, except for a decrease in deep tendon reflexes in some participants in both cities. There was no correlation between Standardized Mini Mental State Examination results and hair mercury levels. We conclude that establishing a monitoring system for mercury levels in fish and humans will be useful in terms of evaluating potential neurotoxic effects. © The Author(s) 2014.

    Summary We sought to assess neurologists' interest in sports neurology and learn about their experience in treating sports-related neurologic conditions. A survey was sent to a random sample of American Academy of Neurology members. A majority of members (77%) see at least some patients with sports-related neurologic issues. Concussion is the most common sports-related condition neurologists treat. More than half of survey participants (63%) did not receive any formal or informal training in sports neurology. At least two-thirds of respondents think it is very important to address the following issues: developing evidence-based return-to-play guidelines, identifying risk factors for long-term cognitive-behavioral sequelae, and developing objective diagnostic criteria for concussion. Our findings provide an up-to-date view of the subspecialty of sports neurology and identify areas for future research. PMID:24790800

    2014-06-01

    This review serves as an overview of neurologic conditions associated with alcohol abuse or withdrawal, including epidemiology, clinical symptoms, diagnostic approach, and treatment. Frequent alcohol abuse and frank alcoholism are very common among adults in the United States. Although rates decline with each decade, as many as 10% of the elderly drink excessively. Given the ubiquitous nature of alcoholism in society, its complications have been clinically recognized for generations, with recent advances focusing on improved understanding of ethanol's biochemical targets and the pathophysiology of its complications. The chronic effects of alcohol abuse are myriad and include neurologic complications through both direct and indirect effects on the central and peripheral nervous systems. These disorders include several encephalopathic states related to alcohol intoxication, withdrawal, and related nutritional deficiencies; acute and chronic toxic and nutritional peripheral neuropathies; and myopathy. Although prevention of alcoholism and its neurologic complications is the optimal strategy, this article reviews the specific treatment algorithms for alcohol withdrawal and its related nutritional deficiency states.

    Introduction: This study was aimed to compare the efficacy and side effects of memantine, an antagonist of the NMDA receptor of glutamate, with risperidone given the fact that glutamate has been noted for its possible effects in the pathogenesis of autism. Risperidone, an atypical antipsychotic, has been approved by FDA for the management of irritability associated with autism. Methods: 30 children, aged 4-17 years, entered an 8-week, randomized trial. Patients were randomly assigned to receive either risperidone or memantine. Autism Behavior Checklist (ABC), Childhood Autism Rating Scale (CARS), Clinical Global Impressions - Improvement (CGI-I) and Clinical Global Impression-Severity (CGI-S) scales were used to assess behavioral symptoms of the patients. Results: Both risperidone and memantine reduced the scores of 4 subscales of ABC as well as the 10-item and the total score of CARS significantly. However, differences between the 2 drugs in the scores of each evaluating scale were not found to be significant. Relatively, larger number of patients on risperidone showed "very much improvement" when assessed by CGI-I scale when compared with those on memantine. Discussion and conclusion: The present study suggests that memantine may have beneficial effects in the treatment of many core symptoms of autism. Therefore, memantine may be considered as a potential medication in the treatment of those autistic children who do not respond or cannot tolerate side effects of risperidone. © Georg Thieme Verlag KG Stuttgart · New York.

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

    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.

    This is a study that updates earlier research on the influence of a front passenger on the risk for severe driver injury in near-side and far-side impacts. It includes the effects of belt use by the driver and passenger, identifies body regions involved in driver injury and identifies the sources for severe, driver head injury. 1997-2015 NASS-CDS data was used to investigate the risk for MAIS 4+F driver injury in near-side and far-side impacts by front-passenger belt use and as a sole occupant in the driver seat. Side impacts were identified with GAD1 = 'L' or 'R' without rollover (rollover ≤ 0). Front-outboard occupants were included without ejection (ejection = 0). Injury severity was defined by MAIS and fatality (F) by TREATMNT = 1 or INJSEV = 4. Weighted data was determined. The risk for MAIS 4+F was determined using the number of occupants with known injury status MAIS 0+F. Standard errors were determined. Overall, belted drivers had greater risks for severe injury in near-side than far-side impacts. As a sole driver, the risk was 0.969% ± 0.212% for near-side and 0.313% ± 0.069% for far-side impacts (p < 0.005). The driver's risk was 0.933% ± 0.430% with an unbelted and 0.596% ± 0.144% with a belted passenger in near-side impacts. The risk was 2.17-times greater with an unbelted passenger (NS). The driver's risk was 0.782% ± 0.431% with an unbelted and 0.361% ± 0.114% with a belted passenger in far-side impacts. The risk was 1.57-times greater with an unbelted passenger (p <0.10). Seatbelt use was 66% to 95% effective in preventing MAIS 4+F injury in the driver. For belted drivers, the head and thorax were the leading body region for AIS 4+ injury. For near-side impacts, the leading sources for AIS 4+ head injury were the left B-pillar, roof and other vehicle. For far-side impacts, the leading sources were the other occupant, right interior and roof (8.5%). Seatbelt use by a passenger lowered the risk for severe driver injury in side impacts. The

    Most of the detrimental effects of using conventional insecticides to control crop pests are now well identified and are nowadays major arguments for replacing such compounds by the use of biological control agents. In this respect, the bacterium Bacillus thuringiensis var. kurstaki and Trichogramma (Hymenoptera: Trichogrammatidae) parasitic wasp species are both effective against lepidopterous pests and can actually be used concomitantly. In this work, we studied the potential side effects of B. thuringiensis var. kurstaki on Trichogramma chilonis females. We first evidenced an acute toxicity of B. thuringiensis on T. chilonis. Then, after ingestion of B. thuringiensis at sublethal doses, we focused on life history traits of T. chilonis such as longevity, reproductive success and the time spent on host eggs patches. The reproductive success of T. chilonis was not modified by B. thuringiensis while a significant effect was observed on longevity and the time spent on host eggs patches. The physiological and ecological meanings of the results obtained are discussed.

    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.

    Nicotinamide, also known as niacinamide, is the amide form of vitamin B3. It is a precursor of essential coenzymes for numerous reactions in the body including adenosine triphosphate (ATP) production. Nicotinic acid, also known as niacin, is converted into nicotinamide in the body. The use of topical nicotinamide in the treatment of acne vulgaris; melasma; atopic dermatitis; rosacea; and oral nicotinamide in preventing nonmelanoma skin cancer is discussed. The possible side effects and consequences of excessive nicotinamide exposure are reviewed, including suggestions nicotinamide might have a role in the development of diabetes, Parkinson's disease, and liver damage. © 2014 Wiley Periodicals, Inc.

    Full Text Available Abstract Background Patient-reported side effect questionnaires offer a simple method for the systematic measurement of drug-related side effects. In order to measure patients' inhaled corticosteroids (ICS related side effect perceptions the 14-day retrospective Inhaled Corticosteroid Questionnaire (ICQ was developed. In this research we aim to assess the construct validity and reliability of the ICQ and test its responsiveness to dose changes in adult asthma patients. Methods In a cross-sectional study, current inhaler users with asthma completed the ICQ (27 with non ICS inhaler; 61 BDP equivalent daily ICS low dose ≤400 μg; 62 mid dose 401–800 μg; and 105 with high dose >800 μg. We generated 3 construct validity hypotheses: 1 a hierarchical dose-response pattern for scoring of the individual items on the ICQ, and statistically significant differences in the scores of each of the 15 ICQ domains by ICS dose group 2 an association between ICS dose and ICQ scoring after adjusting for appropriate confounders in multiple regression; 3 greater convergence between local side effect domains than between systemic and local domains of the scale. Test-retest reliability was assessed on a randomly selected subgroup of patients (n = 73 who also completed the ICQ a second time after 7 days. In a separate longitudinal study, 61 patients with asthma completed the ICQ at baseline and after changing their daily ICS dose, at 2- and 6- months, in order to test the ICQ's responsiveness. Results All three construct validity hypotheses were well supported: 1 a statistically significant difference existed in scores for 14 domains, the high ICS dose group scoring highest; 2 ICS dose independently predicted ICQ scoring after adjusting for confounders; 3 greater convergence existed between local ICQ domains than between local and systemic domains. The ICQ had good reproducibility: test-retest intraclass correlation coefficients were ≥0.69 for all but the 'Facial

    In this article, a research project on mobile safe food consumption system (FoodWiki) is discussed that performs its own inferencing rules in its own knowledge base. Currently, the developed rules examines the side effects that are causing some health risks: heart disease, diabetes, allergy, and asthma as initial. There are thousands compounds added to the processed food by food producers with numerous effects on the food: to add color, stabilize, texturize, preserve, sweeten, thicken, add flavor, soften, emulsify, and so forth. Those commonly used ingredients or compounds in manufactured foods may have many side effects that cause several health risks such as heart disease, hypertension, cholesterol, asthma, diabetes, allergies, alzheimer etc. according to World Health Organization. Safety in food consumption, especially by patients in these risk groups, has become crucial, given that such health problems are ranked in the top ten health risks around the world. It is needed personal e-health knowledge base systems to help patients take control of their safe food consumption. The systems with advanced semantic knowledge base can provide recommendations of appropriate foods before consumption by individuals. The proposed FoodWiki system is using a concept based search mechanism that performs on thousands food compounds to provide more relevant information.

    Antipsychotic-induced metabolic side effects are major concerns in psychopharmacology and clinical psychiatry. Their pathogenetic mechanisms are still not elucidated. Antipsychotic drugs seem to interfere with feeding behaviors and energy balance processes that control metabolic regulation. Reward and energy balance centers in central nervous system constitute the central level of metabolic regulation. The peripheral level consists of skeletal muscles, the liver, the pancreas, the adipose tissue and neuroendocrine connections. Neurotransmitter receptors have crucial roles in metabolic regulation and they are also targets of antipsychotic drugs. Interaction of antipsychotics with neurotransmitters could have both protective and harmful effects on metabolism. Emerging evidence suggests that antipsychotics have different liabilities to induce obesity, diabetes and dyslipidemia. However, this diversity cannot be explained merely by drugs' pharmacodynamic profiles, highlighting the need for further research. Herein, we review the impact of neurotransmitters on metabolic regulation, providing insights into antipsychotic-induced metabolic side effects.

    Full Text Available OBJECTIVES:To evaluate the functional and histological effects of estrogen as a neuroprotective agent after a standard experimentally induced spinal cord lesion.METHODS:In this experimental study, 20 male Wistar rats were divided into two groups: one group with rats undergoing spinal cord injury (SCI at T10 and receiving estrogen therapy with 17-beta estradiol (4mg/kg immediately following the injury and after the placement of skin sutures and a control group with rats only subjected to SCI. A moderate standard experimentally induced SCI was produced using a computerized device that dropped a weight on the rat's spine from a height of 12.5 mm. Functional recovery was verified with the Basso, Beattie and Bresnahan scale on the 2nd, 7th, 14th, 21st, 28th, 35th and 42nd days after injury and by quantifying the motor-evoked potential on the 42nd day after injury. Histopathological evaluation of the SCI area was performed after euthanasia on the 42nd day.RESULTS:The experimental group showed a significantly greater functional improvement from the 28th to the 42nd day of observation compared to the control group. The experimental group showed statistically significant improvements in the motor-evoked potential compared with the control group. The results of pathological histomorphometry evaluations showed a better neurological recovery in the experimental group, with respect to the proportion and diameter of the quantified nerve fibers.CONCLUSIONS:Estrogen administration provided benefits in neurological and functional motor recovery in rats with SCI beginning at the 28th day after injury.

    If a grower uses predatory mites, and should use chemical compounds, he needs to be very careful in his choice of products. The selected products have to be efficient against the target pest and at the same time compatible with the present beneficial's. Useful tools for such product selection under greenhouse circumstances are side effects lists. These lists are freely available on the websites of producing companies of biological control agents. But not all products (e.g. newly developed ones) have been tested for side effects. Moreover the information already available in these tables is not based on field tests. For this reason, we have developed a protocol for quick screening of side effects of chemical plant protection products under field conditions. For these experiments we have chosen the predatory mite Amblyseius swirskii as test organism, because this is an often used phytoseiid mite, which is very sensitive to pesticides. Hibiscus rosa sinensis is the standard reference plant in our side effects trials because the chosen predatory mite has shown very good control of pests on this plant species. The experimental design consists of eight test objects in 4 replications. Test object 1 is a positive reference (water spray) and test object 2 a negative reference (deltamethrin spray, a product with long residual activity against beneficial organisms). The plot size is 0,68 m2 and each plot contains 32 Hibiscus plants. The greenhouse temperature is set at 20±2°C. The test strategy has the following sequence: introduction of an overdose of Amblyseius swirskii mites 14 days before spraying the pesticides > precount of predatory mites 4 days before application (4DBA) > spray application (A) for the 6 test products and for the 2 references > counting's after application (1, 2, 4, 8 en 12 weeks after application = 1 till 12WAA). The counting's of the number of predatory mites are performed on 20 Hibiscus leaves/plot under a binocular. Because of the absence of any

    Full Text Available Hoodia gordonii, a popular appetite suppressant, is widely used as an ingredient in many food supplements despite the fact that supporting scientific evidence is scarce. Recently alarming side effects of H. gordonii products (increased blood pressure and elevated pulse rate have been reported. The aim of our study was to elucidate the underlying mechanism of these symptoms. A H. gordonii-containing product was tested for sympathomimetic activity. Isolated organ experiments on rat uterine rings revealed smooth muscle relaxant effect with a substantial component mediated through β-adrenergic receptors. Chromatographic comparison of the analyzed product and authentic plant material confirmed that the herbal product contained Hoodia spp. extract, and its cardiovascular effects may be linked to the compounds of the plant.

    Neonicotinoid insecticides are successfully applied to control pests in a variety of agricultural crops; however, they may not only affect pest insects but also non-target organisms such as pollinators. This review summarizes, for the first time, 15 years of research on the hazards of neonicotinoids to bees including honey bees, bumble bees and solitary bees. The focus of the paper is on three different key aspects determining the risks of neonicotinoid field concentrations for bee populations: (1) the environmental neonicotinoid residue levels in plants, bees and bee products in relation to pesticide application, (2) the reported side-effects with special attention for sublethal effects, and (3) the usefulness for the evaluation of neonicotinoids of an already existing risk assessment scheme for systemic compounds. Although environmental residue levels of neonicotinoids were found to be lower than acute/chronic toxicity levels, there is still a lack of reliable data as most analyses were conducted near the detection limit and for only few crops. Many laboratory studies described lethal and sublethal effects of neonicotinoids on the foraging behavior, and learning and memory abilities of bees, while no effects were observed in field studies at field-realistic dosages. The proposed risk assessment scheme for systemic compounds was shown to be applicable to assess the risk for side-effects of neonicotinoids as it considers the effect on different life stages and different levels of biological organization (organism versus colony). Future research studies should be conducted with field-realistic concentrations, relevant exposure and evaluation durations. Molecular markers may be used to improve risk assessment by a better understanding of the mode of action (interaction with receptors) of neonicotinoids in bees leading to the identification of environmentally safer compounds.

    Previous research has examined the neurocognitive effects of depression in Parkinson's disease (PD), finding worse performance on tests of cognitive functioning in PD patients with depression as compared to those without depression. However, this research has not considered the effect of side of onset of motor symptoms. Hence, we sought to investigate the interaction between depression and side of onset on working memory in patients with PD. A total of 66 patients with PD completed the Digit Span Backward subtest of the Wechsler Memory Scale-III as well as two other tests of executive functioning. Groups of left hemibody onset (LHO) with and without depression and right hemibody onset (RHO) with and without depression were created. The results indicated significantly lower performance on the measure of working memory for the LHO with depression group, relative to both the LHO without depression and the RHO with depression groups. These findings indicate that working memory is worse in patients with LHO of motor symptoms who are also depressed, and they suggest that this group of patients might experience greater disability and lower quality of life.

    Longer duration of untreated illness, longer duration of current episode, and the severity of medication side effects may negatively impact on the perceived disability and psychosocial impairment of patients with major affective and anxiety disorders. Studies also suggested the involvement of sensory perception in emotional and psychopathological processes. The present study aimed to examine the relationship between Sensory Processing Disorders (SPD), duration of untreated illness and current illness episode, and the severity of side effects related to psychoactive medications. The sample included 178 participants with an age ranging from 17 to 85 years (mean=53.84±15.55). Participants were diagnosed with unipolar Major Depressive Disorder (MDD) (50%), Bipolar Disorder (BD) (33.7%), and Anxiety disorders (16.3%). They completed a socio-demographic questionnaire, the Udvalg for Kliniske Undersøgelser (UKU), and Adolescent/Adult Sensory Profile (AASP) questionnaire. Longer duration of current episode correlated with greater registration of sensory input and lower avoidance from sensory input among unipolar patients; with lower registration of sensory input, and higher tendency for sensory sensitivity/avoidance among bipolar participants; with lower sensory sensitivity/avoidance among anxiety participants, respectively. Also, mean UKU total scores correlated with lower sensory sensitivity among bipolar individuals. SPD expressed in either hypo/hyper sensitivity may serve to clinically characterize subjects with major affective and anxiety disorders.

  12. Stem cells as anticancer drug carrier to reduce the chemotherapy side effect

    Chemotherapy used for cancer treatment, due to the lack of specificity of drugs, is associated to various damaging side effects that have severe impact on patients' quality of life. Over the past 30 years, increasing efforts have been placed on optimizing chemotherapy dosing with the main goal of increasing antitumor efficacy while reducing drug-associated toxicity. A novel research shows that stem cells may act as a reservoir for the anticancer agent, which will subsequently release some of the drug's metabolites, or even the drug in its original form, in vicinity of the cancer cells. These cells may play a dual role in controlling drug toxicity depending on their capacity to uptake and release the chemotherapeutic drug. In our study, we show that Dental Pulp Stem Cells DPSCs are able to rapidly uptake Paclitaxel PTX, and to release it in the culture medium in a time-dependent manner. This resulting conditioned culture medium is to be transferred to breast cancer cells, the MCF-7. By applying Confocal Raman Microscopy, the anticancer drug uptake by the MCF-7 was measured. Surprisingly, the cancer cells -without any direct contact with PTX- showed a drug uptake. This proves that the stem cells carried and delivered the anticancer drug without its modification. It could be a revolution in chemotherapy to avoid the drug's side effects and increase its efficacy.

    In this case study, the process of nutritional diagnosis and intervention conducted at a hospital on a malnourished patient who underwent treatment for a chronic illness (chemotherapy for cancer treatment) was recorded. The patient received his first round of chemotherapy for colorectal cancer, and then a second round after the cancer metastasized to the liver. The patient was malnourished and had experienced weight loss (17% loss in the most recent 3 months) due to side effects of chemotherapy including stomatitis, nausea, and vomiting. Nutritional diagnosis and intervention via the nutrition care process were implemented through two screening rounds, and the quantity of oral intake increased from 28% to 62% of the recommended daily intake. The patient required continuous monitoring and outpatient care after hospital discharge. It is speculated that if a more active patient education and dietary regimen with respect to chemotherapy side effects had been offered after the patient's first chemotherapy cycle, it might have been possible to treat ingestion problems due to stomatitis during the second cycle of chemotherapy and prevent the weight loss. Henceforth, patients receiving chemotherapy should be educated about nutrition management methods and monitored continuously to prevent malnutrition.

    Full Text Available INTRODUCTION: Anabolic steroids (AS are synthetic derivatives of the testosterone molecule. In recent years, AS abuse by athletes of different levels has become more prevalent and circumspect. The objectives of this study were: Recognition of AS abusers, verification of individual biostatistic and demographic parameters, stratification, recognition and evaluation of the AS abuse patterns. METHODS: We constructed specialized questionnaires used to identify users and collect data. In a time period of 12 years, 5074 people were evaluated and the relevant questionnaires were filled, 4146 (81.7% by amateur and 928 (18.3% by recreational athletes. The data provided by the evaluation of the questionnaires were categorized and elaborated. Studied parameters included: types of AS used, percentage of AS abusers in athletic populations, gender percentage, stratification according to severity of abuse, AS used and use parameters, observed side effects. RESULTS: Categorization of the results has four directions: 1. Separation of users according to sex and athletic category, 2. Stratification of users according to AS abuse severity by use of the Abuse Stratification System (AbuStraS. Categorization of AS regimens (AS frequencies, duration, type and doses used by the cohort and 4. The immediate results of AS abuse to the users' organism and the long term influence in a four years time interval. CONCLUSIONS: Contemporary AS users consistently practice overdose polypharmacy. Knowledge of this type of abuse can be beneficial for the treatment of the side effects.

  15. Should Side Effects Influence the Selection of Antidiabetic Therapies in Type 2 Diabetes?

    There are currently over 40 different drugs in 12 distinct classes approved in the USA to treat patients with type 2 diabetes mellitus. This review summarizes our current knowledge about potential side effects of antidiabetic therapy and attempts to apply it to a clinical practice setting. Given the heterogeneity of both the patients and the disease, it is mathematically impossible to test every available drug combination in long-term outcome, prospective, randomized blinded fashion before a clinician decides which agent(s) to prescribe to a specific patient in a given situation. To complicate the clinician's dilemma, there is lack of available tests to predict an individual's response or propensity to side effects. Further, the data available are derived from small, short-term registration trials and typically focus on relative rather than absolute risks of any given drug and do not address the potential adverse outcomes if a patient's diabetes remains untreated. Clinicians have to personalize their choice of antidiabetic therapy based both on the specific characteristics of the patient in front of them (stage of diabetes and its complications, overall health status, socioeconomic situation, other medications present, desire to improve control of diabetes, etc.) and the current knowledge about the relative and absolute balance of benefits and risks of any individual medication in that specific patient. It has to be recognized that this requires constant re-evaluation as database of our experience with antidiabetic therapy expands.

    For virtual reality laparosopic simulation we developed a new, highly immersive simulation mode. The goal of the current pilot study was to investigate if kinetosis or other negative vegetative side effects can be caused by a total virtual training set-up (TVRL). In this study 20 participants with varying degrees of expertise in laparoscopy performed 3 tasks (i.e. ring exchange, fine dissection and cholecystectomy) in regular (VRL) and immersive mode (TVRL) with a head-mounted display (HMD) on a laparoscopic simulator. Aside from performance scores, the heart rate was recorded and the occurrence of vertigo was investigated. Surgical performance was independent of the VR mode (VRL or TVRL). Participants' heart rate was higher in TVRL without reaching statistical significance. Kinetosis occurred in two participants (10%) with a history of motion sickness. Laparoscopic training can take place in a total virtual environment with limited nagative vegetative side effects. Special attention should be paid to participants with a history of motion sickness. The development of TVRL enables new perspectives for surgical training.

    Full Text Available South Africa has the highest proportion of HIV-positive people in the world. HIV cannot be cured; however, there are several major classes of drugs used in its management. Efavirenz is one such agent of the class non-nucleoside reverse transcriptase inhibitors which inhibits the replication of the virus. Efavirenz is associated with causing neuropsychiatric side-effects (NPSEs, with almost 50% of patients experiencing at least one NPSE while on treatment. The NPSEs tend to occur within the first few days of initiation of therapy and resolve spontaneously within the first 4 - 6 weeks, with the most commonly reported being dizziness, insomnia, headache, abnormal dreams and impaired concentration. The plasma level of efavirenz and genetic polymorphisms are thought to play a role in the development of such NPSEs. NPSEs need to be treated according to severity. If necessary, efavirenz may be replaced with nevirapine or lopinavir/ritonavir. It should be remembered that nevirapine may also produce some severe side-effects such as skin abnormalities and hepatotoxicity. The monitoring of patients receiving efavirenz therapy should be ongoing, with those with a history of mental illness requiring closer monitoring than others.

    In the wake of dramatic economic success during the past 2 decades, the specialized field of neurology has undergone a significant transformation in China. With an increase in life expectancy, the problems of aging and cognition have grown. Lifestyle alterations have been associated with an epidemiologic transition both in the incidence and etiology of stroke. These changes, together with an array of social issues and institution of health care reform, are creating challenges for practicing neurologists throughout China. Notable problems include overcrowded, decrepit facilities, overloaded physician schedules, deteriorating physician-patient relationships, and an insufficient infrastructure to accommodate patients who need specialized neurologic care. Conversely, with the creation of large and sophisticated neurology centers in many cities across the country, tremendous opportunities exist. Developments in neurologic subspecialties enable delivery of high-quality care. Clinical and translational research based on large patient populations as well as highly sophisticated technologies are emerging in many neurologic centers and pharmaceutical companies. Child neurology and neurorehabilitation will be fast-developing subdisciplines. Given China's extensive population, the growth and progress of its neurology complex, and its ever-improving quality control, it is reasonable to anticipate that Chinese neurologists will contribute notably to unraveling the pathogenic factors causing neurologic diseases and to providing new therapeutic solutions.

    To investigate the therapeutic effect of neurologic music therapy (NMT) and speech language therapy (SLT) through improvement of the aphasia quotient (AQ) in post-stroke aphasic patients. Twenty-one post-stroke, nonfluent aphasia patients who had ischemic/hemorrhagic stroke on radiologic evaluation were divided into the NMT and SLT groups. They received NMT and SLT for 1 month. Language function was assessed by Korean version-Western Aphasia Battery before and after therapy. NMT consisted of therapeutic singing and melodic intonation therapy, and SLT consisted of language-oriented therapy. Significant improvements were revealed in AQ, repetition, and naming after therapy in the NMT group and improvements in repetition in the SLT group of chronic stroke patients (p<0.05). There were significant improvements in language ability in the NMT group of subacute stroke patients. However, there was no significant improvement in the SLT group of subacute stroke patients. We concluded that the two therapies are effective treatments in the chronic stage of stroke and NMT is effective in subacute post-stroke aphasic patients.

    Full Text Available Deficiency of growth hormone (GH in adults results in a syndrome characterized by decreased muscle mass and exercise capacity, increased visceral fat, impaired quality of life, unfavorable alterations in lipid profile and markers of cardiovascular risk, decrease in bone mass and integrity and increased mortality. When dosed appropriately, GH replacement therapy (GHRT is well tolerated, with a low incidence of side effects, and improves most of the alterations observed in GH deficiency (GHD; beneficial effects on mortality, cardiovascular events and fracture rates, however, remain to be conclusively demonstrated. The potential of GH to act as a mitogen has resulted in concern over the possibility of increased de novo tumors or recurrence of pre-existing malignancies in individuals treated with GH. Though studies of adults who received GHRT in childhood have produced conflicting reports in this regard, long term surveillance of adult GHRT has not demonstrated increased cancer risk or mortality.

    The better knowledge of the mechanisms of nuclear incidents and lessons learned from accidents in the recent past to improve the effectiveness of measures taken following a nuclear accident exposure to fallout of radioactive iodine isotopes. Thus, immediate, passive measures, such as containment, and stopping consumption of contaminated products are paramount. The earliest possible administration of stable iodine as potassium iodide (KI) reduces significantly (up to 90% if taken at the same time of the accident) thyroid radioactive contamination. These tablets should be given in priority to children and pregnant women. The side effects are minor. KI is not recommended for persons aged over 60 years, or for adults suffering from cardiovascular disorders. Copyright © 2016 Elsevier Masson SAS. All rights reserved.

    2014-06-10

    Aiming at providing a comprehensive study of the influence of the cation symmetry and alkyl side chain length on the surface tension and surface organization of ionic liquids (ILs), this work addresses the experimental measurements of the surface tension of two extended series of ILs, namely R,R'-dialkylimidazolium bis[(trifluoromethyl)sulfonyl]imide ([C(n)C(n)im][NTf2]) and R-alkyl-3-methylimidazolium bis[(trifluoromethyl)sulfonyl]imide ([C(n)C(1)im][NTf2]), and their dependence with temperature (from 298 to 343 K). For both series of ILs the surface tension decreases with an increase in the cation side alkyl chain length up to aliphatic chains no longer than hexyl, here labeled as critical alkyl chain length (CACL). For ILs with aliphatic moieties longer than CACL the surface tension displays an almost constant value up to [C12C12im][NTf2] or [C16C1im][NTf2]. These constant values further converge to the surface tension of long chain n-alkanes, indicating that, for sufficiently long alkyl side chains, the surface ordering is strongly dominated by the aliphatic tails present in the IL. The enthalpies and entropies of surface were also derived and the critical temperatures were estimated from the experimental data. The trend of the derived thermodynamic properties highlights the effect of the structural organization of the IL at the surface with visible trend shifts occurring at a well-defined CACL in both symmetric and asymmetric series of ILs. Finally, the structure of a long-alkyl side chain IL at the vacuum-liquid interface was also explored using Molecular Dynamics simulations. In general, it was found that for the symmetric series of ILs, at the outermost polar layers, more cations point one of their aliphatic tails outward and the other inward, relative to the surface, than cations pointing both tails outward. The number of the former, while being the preferred conformation, exceeds the latter by around 75%.

    Full Text Available Introduction The chin-tuck maneuver is the most frequently employed postural maneuver in the treatment of neurogenic oropharyngeal dysphagia caused by encephalic vascular strokes and degenerative diseases. Objective The purpose of this study was to investigate the effectiveness of this maneuver in patients with neurogenic dysphagia and factors that could interfere in it. Methods In this retrospective cohort, we analyzed the medical files and videofluoroscopy exams of 35 patients (19 male – 54% and 16 female – 46%; age range between 20 and 89 years old; mean = 69 years. Results The results suggest that the effectiveness of chin-tuck maneuver is related to the overall degree of dysphagia: the more severe the dysphagia, the less effective the maneuver. Conclusion Chin-tuck maneuver should benefit dysphagic patients with delay in the swallowing trigger, reduced laryngeal elevation, and difficulties to swallow liquids, but is not the best compensatory strategy for patients with severe dysphagia.

    Purpose: Proton minibeam radiation therapy is a novel approach to minimize normal tissue damage in the entrance channel by spatial fractionation while keeping tumor control through a homogeneous tumor dose using beam widening with an increasing track length. In the present study, the dose distributions for homogeneous broad beam and minibeam irradiation sessions were simulated. Also, in an animal study, acute normal tissue side effects of proton minibeam irradiation were compared with homogeneous irradiation in a tumor-free mouse ear model to account for the complex effects on the immune system and vasculature in an in vivo normal tissue model. Methods and Materials: At the ion microprobe SNAKE, 20-MeV protons were administered to the central part (7.2 × 7.2 mm{sup 2}) of the ear of BALB/c mice, using either a homogeneous field with a dose of 60 Gy or 16 minibeams with a nominal 6000 Gy (4 × 4 minibeams, size 0.18 × 0.18 mm{sup 2}, with a distance of 1.8 mm). The same average dose was used over the irradiated area. Results: No ear swelling or other skin reactions were observed at any point after minibeam irradiation. In contrast, significant ear swelling (up to fourfold), erythema, and desquamation developed in homogeneously irradiated ears 3 to 4 weeks after irradiation. Hair loss and the disappearance of sebaceous glands were only detected in the homogeneously irradiated fields. Conclusions: These results show that proton minibeam radiation therapy results in reduced adverse effects compared with conventional homogeneous broad-beam irradiation and, therefore, might have the potential to decrease the incidence of side effects resulting from clinical proton and/or heavy ion therapy.

    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 density as high as 1 μA/μm between graphene flakes. These findings are important for the miniaturization of atomically thin devices.

    The aim of this study was to examine the effect of the side of brain lesion on the ipsilesional hand function of stroke survivors. Twenty-four chronic stroke survivors, equally allocated in 2 groups according to the side of brain lesion (right or left), and 12 sex- and age-matched healthy controls performed the Jebsen-Taylor Hand Function Test (JTHFT), the Nine-Hole Peg Test (9HPT), the maximum power grip strength (PwGS max ) test, and the maximum pinch grip strength (PnGS max ) test. Only the ipsilesional hand of the stroke survivors and both hands (left and right) of the controls were assessed. PwGS max and PnGS max were similar among all tested groups. Performances in JTHFT and 9HPT were affected by the brain injury. Individuals with left brain damage showed better performance in 9HPT than individuals with right brain damage, but performance in JTHFT was similar. Individuals after a brain injury have the capacity to produce maximum strength preserved when using their ipsilesional hand. However, the dexterity of their hands and digits is affected, in particular for stroke individuals with right brain lesion. Copyright © 2017 National Stroke Association. Published by Elsevier Inc.

    Three conjugated polymers with alkyl chains of different lengths are designed and synthesized, and their structure-property relationship as organic thermoelectric materials is systematically elucidated. All three polymers show similar photophysical properties, thermal properties, and mechanical properties; however, their thermoelectric performance is influenced by the length of their side chains. The length of the alkyl chain significantly influences the electrical conductivity of the conjugated polymers, and polymers with a short alkyl chain exhibit better conductivity than those with a long alkyl chain. The length of the alkyl chain has little effect on the Seebeck coefficient. Only a slight increase in the Seebeck coefficient is observed with the increasing length of the alkyl chain. The purpose of this study is to provide comprehensive insight into fine-tuning the thermoelectric properties of conjugated polymers as a function of side-chain engineering, thereby providing a novel perspective into the design of high-performance thermoelectric conjugated polymers. © 2017 WILEY-VCH Verlag GmbH & Co.

    2016-07-01

    Preventive treatment with lithium carbonate is a therapeutic option for chronic cluster headache. Lithium can lead to a broad spectrum of severe side effects, many of which are generally unknown. One week after starting treatment with lithium, a 55-year-old man with chronic cluster headache noticed a strange and unpleasant taste of various foods and a diminished smell. After 4 weeks, he decided to stop the therapy because of these complaints, but 9 months later both taste and smell still had not returned to normal. We present the first description of long-lasting dysgeusia and hyposmia as a side effect of lithium therapy in cluster headache. Dysgeusia has only rarely been reported as a side effect of lithium in other conditions and hyposmia has not previously been reported. Physicians should be aware of this rare, but severe, side effect when prescribing lithium. © 2016 American Headache Society.

    The diver's nervous system is extremely sensitive to high ambient pressure, which is the sum of atmospheric and hydrostatic pressure. Neurological complications associated with diving are a difficult diagnostic and therapeutic challenge. They occur in both commercial and recreational diving and are connected with increasing interest in the sport of diving. Hence it is very important to know the possible complications associated with this kind of sport. Complications of the nervous system may result from decompression sickness, pulmonary barotrauma associated with cerebral arterial air embolism (AGE), otic and sinus barotrauma, high pressure neurological syndrome (HPNS) and undesirable effect of gases used for breathing. The purpose of this review is to discuss the range of neurological symptoms that can occur during diving accidents and also the role of patent foramen ovale (PFO) and internal carotid artery (ICA) dissection in pathogenesis of stroke in divers.

  14. Risks from accidental exposures to engineered nanoparticles and neurological health effects: A critical review

    2010-12-01

    Full Text Available Abstract There are certain concerns regarding the safety for the environment and human health from the use of engineered nanoparticles (ENPs which leads to unintended exposures, as opposed to the use of ENPs for medical purposes. This review focuses on the unintended human exposure of ENPs. In particular, possible effects in the brain are discussed and an attempt to assess risks is performed. Animal experiments have shown that investigated ENPs (metallic nanoparticles, quantum dots, carbon nanotubes can translocate to the brain from different entry points (skin, blood, respiratory pathways. After inhalation or instillation into parts of the respiratory tract a very small fraction of the inhaled or instilled ENPs reaches the blood and subsequently secondary organs, including the CNS, at a low translocation rate. Experimental in vivo and in vitro studies have shown that several types of ENPs can have various biological effects in the nervous system. Some of these effects could also imply that ENPs can cause hazards, both acutely and in the long term. The relevance of these data for risk assessment is far from clear. There are at present very few data on exposure of the general public to either acute high dose exposure or on chronic exposure to low levels of air-borne ENPs. It is furthermore unlikely that acute high dose exposures would occur. The risk from such exposures for damaging CNS effects is thus probably very low, irrespective of any biological hazard associated with ENPs. The situation is more complicated regarding chronic exposures, at low doses. The long term accumulation of ENPs can not be excluded. However, we do not have exposure data for the general public regarding ENPs. Although translocation to the brain via respiratory organs and the circulation appears to be very low, there remains a possibility that chronic exposures, and/or biopersistent ENPs, can influence processes within the brain that are triggering or aggravating

    Full Text Available Background: Antiplatelet drugs with known side effects are given in long term therapies to prevent secondary ischemic stroke. Gastrointestinal side effect is the most prevalent issue. The aim of this study was to identify which antiplatelet drugs have the most gastrointestinal side effects and the duration of administration. Methods: Seven hundred twenty six medical records were obtained from the Medical Record Department of Dr.Hasan Sadikin General Hospital Bandung from August to December 2011. Inclusion criteria were >18 years old and treated by long term antiplatelet drugs with complete medical records. Data analyzed descriptively consist of antiplatelet type, gastrointestinal effects, and drug administration duration. Results: Of 726 medical records only 246 were enrolled this study. Aspirin 80 mg was the most frequent drug given to ischemic stroke patients (65.9%. Gastrointestinal (GI bleeding and nausea were the two side effects mostly found in aspirin >80 mg group (90%; 95% respectively. The side effects was found after less than 3 months in the aspirin >80 mg group, while it took longer to appear in clopidogrel 75 mg group. Conclusions: Aspirin (>80 mg presents the most frequent gastrointestinal side effect compared to low dose aspirin 80 mg , clopidogrel, and combination of clopidogrel and aspirin.

    Ioglicinate plus lidocaine and ioxaglate were used for aortofemoral angiography in 15 patients. Side effects of the two contrast media were compared in a double blind study. Injection of ioxaglate caused significantly less vascular pain. With both contrast agents sensation of heat and increase of heart rate were equal. Unlike ioglicinate plus lidocaine ioxaglate did not induce a significant drop of blood pressure. Angiography using low osmolar contrast media causes less side effects than conventional medium plus local anesthetic.

    In the Malawi ART programme, 92% of 250,000 patients are using the standard first-line regime of stavudine-lamivudine-nevaripine. National ART reports indicate side effects, much less than expected from literature. We interviewed adult patients on standard first-line ART for at least one year, after routine visits to an urban clinic in Blantyre, Malawi. We determined the prevalence of symptoms that are common side-effects, described discrepancies between symptoms that patients reported to us and those that had been recorded by attending staff as side-effects in the point-of-care electronic monitoring system, and studied factors associated with such discrepancies. Of 170 participants, 75 (44%) reported at least one symptom, most common were symptoms suggesting peripheral neuropathy (n=57) and lipodystrophy (n=16). Forty-six (66%) symptomatic patients said they reported symptoms to attending ART staff. Side-effects were recorded in the clinic database for just 4 patients. Toxicity recording was too low for meaningful analysis of factors associated with discrepancies between reporting and recording of side-effects. The prevalence of symptoms indicating characteristic side-effects of the standard first-line regimen was 39% based on interviews, and 2% in the electronic monitoring system. There was gross under-recording of side-effects in this setting, mainly due to not recording by ART staff. Pressure of work and insufficient perceived benefit of side-effect recording are suspected causes. Local and national ART reports do not reflect the true toxicity of the standard first line regimen.

    To identify the side effects most important to glucocorticoid (GC) users through a survey of a UK online health community (Healthunlocked.com). Online cross-sectional survey. Participants were recruited through Healthunlocked.com, an online social network for health. Adults who were currently taking GCs, or had taken GCs in the past month. Responders scored the importance of listed side effects from 1 to 10, with 10 being of high importance to them. For each side effect, histograms were plotted, and the median rating and IQR were determined. Side effects were ranked by median ranking (largest to smallest) and then IQR (smallest to largest). The scores were categorised as low (scores 1-3), medium (scores 4-7) and high (scores 8-10) importance. 604 responders completed the survey. Histograms of side effect scores showed a skew towards high importance for weight gain, a U-shaped distribution for cardiovascular disease (CVD), diabetes, eye disease and infections, and a skew towards low importance for acne. When ranked, the side effect of most importance to responders was weight gain (median score=9, IQR 6-10) followed by insomnia and moon face with equal median score (8) and IQR (5-10). Three serious side effects, CVD, diabetes and infections, were ranked of lower importance overall but had wide ranging scores (median score=8, IQR 1-10). The three most highly rated side effects were not clinically serious but remained important to patients, perhaps reflecting their impact on quality of life and high prevalence. This should be taken into consideration when discussing treatment options and planning future GC safety studies. Published by the BMJ Publishing Group Limited.

    Ghrelin, a peptide released by the stomach that plays a major role in regulating energy metabolism, has recently been shown to have effects on neurobiological behaviors. Ghrelin enhances neuronal survival by reducing apoptosis, alleviating inflammation and oxidative stress, and accordingly improving mitochondrial function. Ghrelin also stimulates the proliferation, differentiation and migration of neural stem/progenitor cells (NS/PCs). Additionally, the ghrelin is benefit for the recovery of memory, mood and cognitive dysfunction after stroke or traumatic brain injury. Because of its neuroprotective and neurogenic roles, ghrelin may be used as a therapeutic agent in the brain to combat neurodegenerative disease. In this review, we highlight the pre-clinical evidence and the proposed mechanisms underlying the role of ghrelin in physiological and pathological brain function. Copyright © 2016 Elsevier Ltd.

    The aim of this study was to compare the side-effects of glyphosate to the parasitoid Telenomus remus Nixon (Hymenoptera: Platygastridae) when parasitoids were exposed to this chemical at the pupal (inside host eggs) and adult stages. Bioassays were conducted under laboratory conditions according to the International Organization for Biological Control (IOBC) standard methods for testing side-effects of pesticides to egg parasitoids. Different glyphosate-based pesticides (Roundup Original®, Roundup Ready®, Roundup Transorb®, Roundup WG®, and Zapp Qi®) were tested at the same acid equivalent concentration. Treatments were classified following the IOBC toxicity categories as (1) harmless, (2) slightly harmful, (3) moderately harmful, and (4) harmful. When tested against T. remus adults, Roundup Original®, Roundup Ready®, Roundup Transorb®, and Roundup WG® reduced parasitism 2 days after parasitoid emergence, being classified as slightly harmful. Differently, when tested against T. remus pupae, all tested glyphosate-based products did not differ in their lethal effect and therefore did not reduce T. remus adult emergence or parasitism capacity, being classified as harmless. However, differences on sublethal toxicity were found. Parasitism of individuals emerging from parasitized eggs sprayed at the pupal stage of T. remus with Zapp Qi® was lower compared to control, but parasitism was still higher than 66%, and therefore, Zapp Qi® was still classified as harmless. In conclusion, all tested glyphosate-based products can be used in agriculture without negative impact to T. remus as none was classified as harmful or moderately harmful to this parasitoid when exposure occurred at the pupal or adult stages.

    Full Text Available Background and Aim: Stroke is one of the most important factors of mortality and disability in the world. Free radicals are produced following ischemic stroke and they play a central role in breaking the blood-brain barrier and  causing brain edema formation. The aim of the current study was to evaluate the effect of hydro- alcoholic extract of Origanum vulgare on brain edema and neurologic deficit in a rat stroke model. Materials and Methods: In thisexperimental study, 35 male Wistar rats were randomly divided into 5 equal groups.  The first  two groups (control and Sham received distilled water, while three treatment groups received oral Origanum vulgare extract for 30days (50,75and 100 mg/kgdaily, respectively.  Two hours after the last dose of Origanum vulgare extract,each main group underwent  a 60 min middle cerebral artery occlusion.  Then, the assessment of blood brain edema, and neurologic deficits analysis were done . Brain edema (brain water content was analyzed by One-Way ANOVA using LSD method and neurologic deficits analysis by means of Mann-Whitney U, and P<0.05 was taken as the significant level. Results: Origanum vulgare extract reduced brain edema in the experimental groups of 50 (82.49±0.47, 75 (80.89±0.63 and 100 mg/kg/day (80.80±0.66 compared to the control group (84.46±0.67. The neurologic deficit scores in the experimental groups of 75and 100mg/kg/day, compared with control group, but neurologic deficit scores did not affect the group receiving the dose 50 mg/kg. Conclusion:  The obtained data indicate that Origanum vulgar extract via reduction of brain edema and neurologic deficits scorescan have a protective effect on the stroke model.

  4. Translocation and potential neurological effects of fine and ultrafine particles a critical update

    Geiser Marianne

    2006-09-01

    Full Text Available Abstract Particulate air pollution has been associated with respiratory and cardiovascular disease. Evidence for cardiovascular and neurodegenerative effects of ambient particles was reviewed as part of a workshop. The purpose of this critical update is to summarize the evidence presented for the mechanisms involved in the translocation of particles from the lung to other organs and to highlight the potential of particles to cause neurodegenerative effects. Fine and ultrafine particles, after deposition on the surfactant film at the air-liquid interface, are displaced by surface forces exerted on them by surfactant film and may then interact with primary target cells upon this displacement. Ultrafine and fine particles can then penetrate through the different tissue compartments of the lungs and eventually reach the capillaries and circulating cells or constituents, e.g. erythrocytes. These particles are then translocated by the circulation to other organs including the liver, the spleen, the kidneys, the heart and the brain, where they may be deposited. It remains to be shown by which mechanisms ultrafine particles penetrate through pulmonary tissue and enter capillaries. In addition to translocation of ultrafine particles through the tissue, fine and coarse particles may be phagocytized by macrophages and dendritic cells which may carry the particles to lymph nodes in the lung or to those closely associated with the lungs. There is the potential for neurodegenerative consequence of particle entry to the brain. Histological evidence of neurodegeneration has been reported in both canine and human brains exposed to high ambient PM levels, suggesting the potential for neurotoxic consequences of PM-CNS entry. PM mediated damage may be caused by the oxidative stress pathway. Thus, oxidative stress due to nutrition, age, genetics among others may increase the susceptibility for neurodegenerative diseases.

    Full Text Available Introduction. We present the case of a patient who developed lithium toxicity with normal therapeutic levels, as a result of pharmacokinetic interaction with Valsartan, and probable Neuroleptic Malignant Syndrome from the ensuing lithium toxicity. Case Presentation. A 59-year old black male with bipolar disorder maintained on lithium and fluphenazine therapy presented with a 2 week history of worsening confusion, tremor, and gait abnormality. He recently had his dose of Valsartan increased. At presentation, patient had signs of autonomic instability, he was confused, dehydrated, and had rigidity of upper extremities. Significant labs on admission were lithium level-1.2, elevated CK-6008, leukocytosis WBC-22, and renal impairment; Creatinine-4.1, BUN-35, HCO3-20.1, and blood glucose 145. CT/MRI brain showed old cerebral infarcts, and there was no evidence of an infective process. Lithium and fluphenazine were discontinued, his lithium levels gradually decreased, and he improved with supportive treatment including rehydration and correction of electrolyte imbalance. Conclusions. This case illustrates that lithium toxicity can occur within therapeutic levels, and the neurotoxic effect of lithium can include Neuroleptic Malignant Syndrome. Clinicians should be aware of the risk associated with drug interactions with lithium.

  7. Development of NMDAR antagonists with reduced neurotoxic side effects: a study on GK11.

    Directory of Open Access Journals (Sweden)

    Delphine Vandame

    Full Text Available The NMDAR glutamate receptor subtype mediates various vital physiological neuronal functions. However, its excessive activation contributes to neuronal damage in a large variety of acute and chronic neurological disorders. NMDAR antagonists thus represent promising therapeutic tools that can counteract NMDARs' overactivation. Channel blockers are of special interest since they are use-dependent, thus being more potent at continuously activated NMDARs, as may be the case in pathological conditions. Nevertheless, it has been established that NMDAR antagonists, such as MK801, also have unacceptable neurotoxic effects. Presently only Memantine is considered a safe NMDAR antagonist and is used clinically. It has recently been speculated that antagonists that preferentially target extrasynaptic NMDARs would be less toxic. We previously demonstrated that the phencyclidine derivative GK11 preferentially inhibits extrasynaptic NMDARs. We thus anticipated that this compound would be safer than other known NMDAR antagonists. In this study we used whole-genome profiling of the rat cingulate cortex, a brain area that is particularly sensitive to NMDAR antagonists, to compare the potential adverse effects of GK11 and MK801. Our results showed that in contrast to GK11, the transcriptional profile of MK801 is characterized by a significant upregulation of inflammatory and stress-response genes, consistent with its high neurotoxicity. In addition, behavioural and immunohistochemical analyses confirmed marked inflammatory reactions (including astrogliosis and microglial activation in MK801-treated, but not GK11-treated rats. Interestingly, we also showed that GK11 elicited less inflammation and neuronal damage, even when compared to Memantine, which like GK11, preferentially inhibits extrasynaptic NMDAR. As a whole, our study suggests that GK11 may be a more attractive therapeutic alternative in the treatment of CNS disorders characterized by the overactivation

    Full Text Available The aim of this study was to investigate the effect of three different court dimensions on the internal and external load during small-sided handball games. Six male amateur handball players took part in this study and participated in three different 8-min 3vs3 (plus goalkeepers small-sided handball games (each repeated twice. The three court dimensions were 12×24m, 30×15m and 32×16m. Through Global Positioning System devices (SPI pro elite 15Hz, GPSports and video analysis, the following parameters were recorded: cyclic and acyclic movements (distance covered and number of technical actions executed, heart rate, and rating of perceived exertion (RPE. Total distance travelled increased with court dimensions (885.2m ± 66.6m in 24×12m; 980.0m ± 73.4m in 30×15m; 1095.0m ± 112.9m in 32×16m, p 5.2 m·s-1 highlighted substantial differences: playing with the 30×15m court in comparison to the 24×12m, the players covered less distance in the first speed zone (p = 0.012; ES = 0.70 and more distance in the second (p = 0.049; ES = 0.73 and third (p = 0.012; ES = 0.51 speed zones. Statistical differences were also found between the 24×12m and 32×16m courts: the players covered more distance in the second and third speed zones (p = 0.013, ES = 0.76; p = 0.023 ES = 0.69 with the 32×16m court in comparison to the 24×12m. There was no significant effect of court dimensions on the technical parameters (number of team actions, passes, piston movements toward goal and defensive activities, the number of specific handball jumps and changes of direction, and the time spent in the different heart rate zones. Considering the average data of all the experimental conditions together (24×12m, 30×15m, 32×16m, a pronounced statistical difference was highlighted between the values in first two HR zones and the last two (p < 0.05; large ES.

    Molham Abdulsamad

    2016-01-01

    Full Text Available Viekira Pak is a new direct-acting antiviral agent that has an excellent efficacy in treating patients with chronic HCV. FDA released a safety warning that Viekira Pak can cause serious liver injury mostly in patients with underlying advanced liver disease. We report the first case of fatal lactic acidosis presenting 3 days after initiating therapy with Viekira Pak. Although it is very hard to precisely determine the cause of lactic acidosis, our case highlights an unusual side effect that ensued after starting the medication. Given the complexity of drug-drug interactions that can happen with the new direct-acting antiviral agents and the paucity of data regarding coadministration and methods of monitoring, a thorough review should be pursued prior to initiating these medications.

    Full Text Available This paper investigates the effect of increased demand-side flexibility (DSF on integration and market value of variable renewable energy sources (VRE. Using assumed potentials, system-optimal within-day shifts in demand are investigated for the Northern European power markets in 2030, applying a comprehensive partial equilibrium model with high temporal and spatial resolution. Increased DSF is found to cause only a minor (less than 3% reduction in consumers’ cost of electricity. VRE revenues are found to increase (up to 5% and 2% for wind and solar power, respectively, and total VRE curtailment decreases by up to 7.2 TWh. Increased DSF causes only limited reductions in GHG emissions. The emission reduction is, however, sensitive to underlying assumptions. We conclude that increased DSF is a promising measure for improving VRE integration. However, low consumers’ savings imply that policies stimulating DFS will be needed to fully use the potential benefits of DSF for VRE integration

    Poly-dimethylsiloxane (PDMS) polymers finishing of Polyamide-6,6 (PA66) fabrics involves ionic interactions between reactive groups on the PDMS polymers and the ones of the textile fabric. Such interactions could be strengthened by a pretreatment with a fixing agent to promote either ion-ion and H-bonding and ion-dipole forces. These forces could contribute towards the building of substantial PDMS-PA66 systems and the achieving of better adhesion properties to fabrics. Four different silicone polymers based on PDMS were applied on a synthetic tanning agent (syntan) finished Polyamide-6,6 fabric under acid conditions. Soxhlet extraction method and ATR FT-IR technique were used to investigate the application conditions. The finishing parameters such as pH and temperature together with fastness, mechanical and performance properties of the treated samples were studied and related to PDMS side chains effect on syntan functionalized Polyamide fabric.

    1982-12-01

    Lumbar myelographies were carried out with lopamidol and locarmat of identical concentrations of iodine in 2 groups of 20 patients each. In about one-third of the cases, clinical side effects and EEG changes were found after the examination without difference with the exception of one seizure and one state of confusion which occurred only after locarmat. Resorption of the contrast media was judged by CT examinations of the lumbar spine and the head. There was a more rapid decrease of lumbar contrast density in patients with a narrow lumbar sac which was accompanied by a more rapid intracranial accumulation of the contrast medium. This may be due to a more active transport of cerebrospinal fluid in this group of patients.

    2016-01-01

    Full Text Available This paper presents a research for the 3D flow of a generalized Burgers’ fluid between two side walls generated by an exponential accelerating plate and a constant pressure gradient, where the no-slip assumption between the exponential accelerating plate and the Burgers’ fluid is no longer valid. The governing equations of the generalized Burgers’ fluid flow are established by using the fractional calculus approach. Exact analytic solutions for the 3D flow are established by employing the Laplace transform and the finite Fourier sine transform. Furthermore, some 3D and 2D figures for the fluid velocity and shear stress are plotted to analyze and discuss the effects of various parameters.

    Full Text Available There are many local and systemic side-effects of topical corticosteroids. To the best of our Knowledge, Hidradenitis Supportive (HS due to topical corticosteroids has not been reported previously. We report a 39-year old, male patient who started himself a topical corticosteroid Pander Plus cream because of itching, scaly lesions over groins and buttocks since 6 months. After 4 months of topical treatment, he developed pus discharging sinuses over both groins and buttocks. Based on patient history, clinical and laboratory findings and the exclusion of other diagnoses, HS points out the use of topical corticosteroids. The case well highlights this unusual condition and represents the first case reported in India to our best of the knowledge. Having performed thorough literature search I would like to discuss in this report the evidence for this relation and stress the importance of appropriate usage of topical corticosteroids.

    Osteoarthritis is a burdensome disease that causes progressive damage to articular cartilage. Non-steroidal anti-inflammatory drugs (NSAIDs) are one of the preferred treatments for symptomatic relief. However, NSAIDs can cause serious dose-dependent side effects, which has prompted experts to recommend the minimization of NSAID dosage. Areas covered: This review focuses on three broad strategies that are currently being investigated or implemented to minimize NSAID dosage: nano-formulation, encapsulation, and topical delivery. The benefits, challenges and current status of these methods are discussed. Expert opinion: Multiple strategies are under investigation to lower NSAID dosage. There is great potential in developing formulations that utilize more than one of these strategies together. However, there are challenges to developing these lower dose preparations. In order to maximize the clinical potential of the abundance of NSAIDs that are both available and being developed, there is a major need for additional clinical studies directly comparing safety and efficacy of different preparations.

    A 45-year-old woman presented to our outpatient clinic with reddish eruptions in both palms. We have learned that she was prescribed metoprolol at another medical center to treat new onset hypertension. On her physical examination there were no associated lesions on the body. All other physical findings, as well as blood chemistry, urine analysis, and complete blood count, were found to be normal. After her consultation with the dermatology department, palmar psoriasis due to metoprolol therapy was diagnosed. The personal and family history of the patient yielded no history for psoriasis. Metoprolol therapy was withdrawn and topical treatment with corticosteroid was recommended. The patient has returned to the clinic subsequently, with no recurrence of the lesions. Psoriazis is one of the rare side effects of beta-blocker therapy.

    2012-07-01

    Full Text Available Abstract Bisphosphonates are recommended in the treatment of osteoporosis and some cancers, in which case they prevent the appearance of bone metastasis. The patients taking bisphosphonates are at increased risk of developing bisphosphonate-related osteonecrosis of jaw (BRONJ which is characterised by the presence of an un-healing wound after dental surgery. BRONJ might represent an anti-angiogenic side effect. However, the real number of patients with BRONJ might be higher than currently recorded. Considering the differential diagnosis which includes various primary and secondary cancers, a correct histopathological diagnosis is very important. The morphological criteria for diagnosis of BRONJ are highlighted in this material.

    The aim of this study was to retrospectively evaluate the patient effective dose (ED) for different PET/CT procedures performed with a variety of PET radiopharmaceutical compounds. PET/CT studies of 210 patients were reviewed including Torso (n = 123), Whole body (WB) (n = 36), Head and Neck Tumor (HNT) (n = 10), and Brain (n = 41) protocols with (18)FDG (n = 170), (11)C-CHOL (n = 10), (18)FDOPA (n = 10), (11)C-MET (n = 10), and (18)F-florbetapir (n = 10). ED was calculated using conversion factors applied to the radiotracer activity and to the CT dose-length product. Total ED (mean ± SD) for Torso-(11)C-CHOL, Torso-(18)FDG, WB-(18)FDG, and HNT-(18)FDG protocols were 13.5 ± 2.2, 16.5 ± 4.5, 20.0 ± 5.6, and 15.4 ± 2.8 mSv, respectively, where CT represented 77, 62, 69, and 63% of the protocol ED, respectively. For (18)FDG, (18)FDOPA, (11)C-MET, and (18)F-florbetapir brain PET/CT studies, ED values (mean ± SD) were 6.4 ± 0.6, 4.6 ± 0.4, 5.2 ± 0.5, and 9.1 ± 0.4 mSv, respectively, and the corresponding CT contributions were 11, 14, 23, and 26%, respectively. In (18)FDG PET/CT, variations in scan length and arm position produced significant differences in CT ED (p PET/CT protocols with different radiopharmaceuticals ranged between 4.6 and 20.0 mSv. The major contributor to total ED for body protocols is CT, whereas for brain studies, it is the PET radiopharmaceutical.

    Full Text Available Background & objectives : The surgery of breast cancer like any other surgeries may bring about some problems and complications, which the knowledge of these problems may be an effective way for prevention or dealing with the complications. The motor and sensory impairments in the upper limb of the surgery side necessitate the utilization of the rehabilitation methods. The main purpose of this research was to show the effect of Pilates exercise on range of motion and edema of upper limb in females suffering from breast cancer after going through surgery.   Methods: This quasi- experimental study was conducted on 25 patients randomly chosen among the patients referring to Cancer Institute. The designed exercise included five "Mat Pilates" moves which were done for 15 sessions until the patient reached fatigue borderlines. Meantime, the control group was doing routine active exercises in physiotherapy center. The range of motion and edema of upper limb was measured before and after applying the designed exercise. For describing the data, the mean and standard deviation, and for inferential analysis, the correlated T-tests and one way analysis of variance were used in level of significance of 5%, to compare the variants before and after applying the designed exercise.   Results: The results showed a significant difference between the flexion, extension, and internal, external rotation of shoulder, flexion and extension of elbow, flexion, extension, supination deviation and pronation deviation of the wrist and forearm before and after experiment in Pilates group. While in the control group, flexion, extension, internal and external rotation of shoulder, flexion and extension of elbow, and flexion of wrist showed a significant difference before and after the experiment.   Conclusion: The use of Pilates exercise after mastectomy surgery can increase the range of motion of the upper limb in the involved side of the patients, and decrease the edema

    The side effects of antiretroviral (ARV) therapy are linked to altered quality of life and adherence. Poor adherence has also been associated with low health-literacy skills, with an uninformed patient more likely to make ARV-related decisions that compromise the efficacy of the treatment. Low literacy skills disempower patients in interactions with healthcare providers and preclude the use of existing written patient information materials, which are generally written at a high reading level. Visual images or pictograms used as a counselling tool or included in patient information leaflets have been shown to improve patients' knowledge, particularly in low-literate groups. The objective of this study was to design visuals or pictograms illustrating various ARV side effects and to evaluate them in a low-literate South African Xhosa population. Core images were generated either from a design workshop or from posed photos or images from textbooks. The research team worked closely with a graphic artist. Initial versions of the images were discussed and assessed in group discussions, and then modified and eventually evaluated quantitatively in individual interviews with 40 participants who each had a maximum of 10 years of schooling. The familiarity of the human body, its facial expressions, postures and actions contextualised the information and contributed to the participants' understanding. Visuals that were simple, had a clear central focus and reflected familiar body experiences (e.g. vomiting) were highly successful. The introduction of abstract elements (e.g. fever) and metaphorical images (e.g. nightmares) presented problems for interpretation, particularly to those with the lowest educational levels. We recommend that such visual images should be designed in collaboration with the target population and a graphic artist, taking cognisance of the audience's literacy skills and culture, and should employ a multistage iterative process of modification and

    Full Text Available Nowadays total inlet temperature of gas turbine is far above the permissible metal temperature; as a consequence, advanced cooling techniques must be applied to protect from thermal stresses, oxidation and corrosion the components located in the high pressure stages, such as the blade trailing edge. A suitable design of the cooling system for the trailing edge has to cope with geometric constraints and aerodynamic demands; state-of-the-art of cooling concepts often use film cooling on blade pressure side: the air taken from last compressor stages is ejected through discrete holes or slots to provide a cold layer between hot mainstream and the blade surface. With the goal of ensuring a satisfactory lifetime of blades, the design of efficient trailing edge film cooling schemes and, moreover, the possibility to check carefully their behavior, are hence necessary to guarantee an appropriate metal temperature distribution. For this purpose an experimental survey was carried out to investigate the film covering performance of different pressure side trailing edge cooling systems for turbine blades. The experimental test section consists of a scaled-up trailing edge model installed in an open loop suction type test rig. Measurements of adiabatic effectiveness distributions were carried out on three trailing edge cooling system configurations. The baseline geometry is composed by inclined slots separated by elongated pedestals; the second geometry shares the same cutback configuration, with an additional row of circular film cooling holes located upstream; the third model is equipped with three rows of in-line film cooling holes. Experiments have been performed at nearly ambient conditions imposing several blowing ratio values and using carbon dioxide as coolant in order to reproduce a density ratio close to the engine conditions (DR=1.52. To extend the validity of the survey a comparison between adiabatic effectiveness measurements and a prediction by

    Full Text Available Abstract Background We present the case of a 52-year-old woman with depression who developed extrapyramidal symptoms (mainly parkinsonism and suicidal ideation while on fluoxetine. Methods The patient underwent neurological and neuroimaging examination. Results The patient's neurological and neuroimaging examinations were normal and there was no other cause of extrapyramidal symptoms. The patient showed remission of the aforementioned symptomatology when fluoxetine was discontinued. Conclusions This case shows that fluoxetine can be associated with extrapyramidal symptoms, and this may have an aggravating affect on clinical depression progress and the emergence of suicidal ideation.

    To evaluate effectiveness of a face-to-face and an online fatigue self-management programme and to compare these to two control groups (information-only and no-intervention) in a sample of adults (n = 115) with neurological conditions reporting extreme fatigue. Non-equivalent pre-test post-test control group design using the Fatigue Impact Scale, Personal Wellbeing Index and Activity Card Sort as primary outcome measures. Participants in the two intervention groups and the information-only group showed clinically significant improvements in fatigue over time (p < 0.05). When compared to the no-intervention group, face-to-face participants showed significantly greater improvement in overall and cognitive fatigue, while participants in the online group showed significant improvement in self-efficacy and stress. Participation in either the online or face-to-face programme appears to result in improved self-management, however, with different potency depending on outcomes. The improvement in the online information only group further complicates the understanding of the results. With few other comparisons of online and face-to-face self-management protocols available, further research is needed to understand differential impacts which may be related to the delivery format, the rural versus urban split of participants or other unknown factors.

  7. The use of growth factors to manage the hematologic side effects of PEG-interferon alfa and ribavirin.

    Collantes, Rochelle S; Younossi, Zobair M

    2005-01-01

    Hematologic side effects (anemia, neutropenia, and thrombocytopenia) of combination therapy with pegylated (PEG)-interferon alfa and ribavirin are commonly encountered during antiviral therapy for chronic hepatitis C (HCV). An important consequence of these side effects is dose modification of PEG-interferon alfa, ribavirin, or both. Dose modification (including discontinuation) diminishes the efficacy of optimal treatment regimen for HCV and may have a negative impact on sustained virologic response. Additionally, fatigue associated with anemia may impair patients' quality of life. The clinical implications of neutropenia or thrombocytopenia are less clear than for anemia; nevertheless, severe infection and bleeding are uncommon. Dose adjustments effectively treat these hematologic side effects, but the resulting suboptimal dosing and potential impact on virologic response are major concerns. Recent attempts to maximize adherence to the optimal treatment regimen have used hematopoietic growth factors rather than dose adjustment to treat side effects. Research on growth factor support has focused on anemia and neutropenia. Epoetin alfa and darbepoetin alfa are erythropoietic growth factors that effectively increase hemoglobin while maintaining the optimal ribavirin dose and improving patients' quality of life. Preliminary work suggests that filgrastim, granulocyte colony stimulating factors, may be an effective treatment of interferon-induced neutropenia. Although this early work shows tremendous promise for managing hematologic side effects of combination therapy for HCV, and potentially enhancing adherence, further research is needed to clarify the efficacy, safety, and cost-effectiveness of growth factors in the management of patients with chronic HCV.

    The use of caffeine containing energy drinks has dramatically increased in the last few years, especially in the sport context because of its reported ergogenic effect. The ingestion of low to moderate doses of caffeinated energy drinks has been associated with adverse side effects such as insomnia or increased nervousness. The aim of the present study was to assess psycho-physiological changes and the prevalence of side effects resulting from the ingestion of 3 mg caffeine/kg body mass in the form of an energy drink. In a double-blind and placebo controlled experimental design, ninety experienced and low-caffeine-consuming athletes (fifty-three male and thirty-seven female) in two different sessions were provided with an energy drink that contained 3 mg/kg of caffeine or the same decaffeinated energy drink (placebo; 0 mg/kg). At 60 min after the ingestion of the energy drink, participants completed a training session. The effects of ingestion of these beverages on psycho-physiological variables during exercise and the rate of adverse side effects were measured using questionnaires. The caffeinated energy drink increased self-perceived muscle power during exercise compared with the placebo beverage (6·41 (sd 1·7) v. 5·66 (sd 1·51); P= 0·001). Moreover, the energy drink produced a higher prevalence of side effects such as insomnia (31·2 v. 10·4 %; Pdrink. There were no sex differences in the incidence of side effects (P>0·05). The ingestion of an energy drink with 3 mg/kg of caffeine increased the prevalence of side effects. The presence of these side effects was similar between male and female participants.

    PETROBRAS has been using THPS biocide since 2000 to control sulphate reducing bacteria (SRB) and H{sub 2}S generation in FPSO's tanks, storage tanks, seawater injection systems, produced water systems and hydrostatic testings. The advantage of this product over other biocides is to be effective against sessile SRB and to have low environmental impact and low risk to operators' health. Since 2005 the use of THPS was also extended to oil pipelines and has being demonstrating high efficacy in controlling sessile SRB and sulfide formation, even in fluids with very low water cut (BSW < 1%). However, some deleterious effects were observed when THPS (formulated with 75% of active ingredient) was dosed continuously in the produced fluids, in high concentration and/or for long periods. This paper presents the results of THPS treatment in two PETROBRAS' oil pipelines and describes the side effects that were detected during the biocide injection. The actions taken to minimize these harmful effects, without losing the good biocide efficiency were also presented. (author)

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

    Full Text Available Children undergoing cranial radiation therapy (CRT for pediatric central nervous system malignancies are at increased risk for neurological deficits later in life. We have developed a model of neurotoxic damage in adult Drosophila following irradiation during the juvenile stages with the goal of elucidating underlying neuropathological mechanisms and of ultimately identifying potential therapeutic targets. Wild-type third-instar larvae were irradiated with single doses of γ-radiation, and the percentage that survived to adulthood was determined. Motor function of surviving adults was examined with a climbing assay, and longevity was assessed by measuring lifespan. Neuronal cell death was assayed by using immunohistochemistry in adult brains. We also tested the sensitivity at different developmental stages by irradiating larvae at various time points. Irradiating late third-instar larvae at a dose of 20 Gy or higher impaired the motor activity of surviving adults. A dose of 40 Gy or higher resulted in a precipitous reduction in the percentage of larvae that survive to adulthood. A dose-dependent decrease in adult longevity was paralleled by a dose-dependent increase in activated Death caspase-1 (Dcp1 in adult brains. Survival to adulthood and adult lifespan were more severely impaired with decreasing larval age at the time of irradiation. Our initial survey of the Drosophila Genetic Reference Panel demonstrated that differences in genotype can confer phenotypic differences in radio-sensitivity for developmental survival and motor function. This work demonstrates the usefulness of Drosophila to model the toxic effects of radiation during development, and has the potential to unravel underlying mechanisms and to facilitate the discovery of novel therapeutic interventions.

    Children undergoing cranial radiation therapy (CRT) for pediatric central nervous system malignancies are at increased risk for neurological deficits later in life. We have developed a model of neurotoxic damage in adult Drosophila following irradiation during the juvenile stages with the goal of elucidating underlying neuropathological mechanisms and of ultimately identifying potential therapeutic targets. Wild-type third-instar larvae were irradiated with single doses of γ-radiation, and the percentage that survived to adulthood was determined. Motor function of surviving adults was examined with a climbing assay, and longevity was assessed by measuring lifespan. Neuronal cell death was assayed by using immunohistochemistry in adult brains. We also tested the sensitivity at different developmental stages by irradiating larvae at various time points. Irradiating late third-instar larvae at a dose of 20 Gy or higher impaired the motor activity of surviving adults. A dose of 40 Gy or higher resulted in a precipitous reduction in the percentage of larvae that survive to adulthood. A dose-dependent decrease in adult longevity was paralleled by a dose-dependent increase in activated Death caspase-1 (Dcp1) in adult brains. Survival to adulthood and adult lifespan were more severely impaired with decreasing larval age at the time of irradiation. Our initial survey of the Drosophila Genetic Reference Panel demonstrated that differences in genotype can confer phenotypic differences in radio-sensitivity for developmental survival and motor function. This work demonstrates the usefulness of Drosophila to model the toxic effects of radiation during development, and has the potential to unravel underlying mechanisms and to facilitate the discovery of novel therapeutic interventions. © 2015.

    We have read several publications of great authority on the neurological profession in the last two years in which were expressed assessments of the current situation combined with opinions about neurology and the necessity to reorganize neurological patient care. These articles took up the question of neurorehabilitation too. The authors, who on a daily basis, deal with the rehabilitation of people with disabilities as a consequence of neurological conditions, summarize some important definitions of rehabilitation medicine and the present system of neurological rehabilitation, as it is defined by the rehabilitation profession.

    In terms of efficacy, several previous studies have shown that the success rate in inhibiting preterm labor was not different between magnesium sulfate and ritodrine. However, there is a paucity of information regarding the efficacy of both medications after consideration of intra-amniotic infection, which is one of the most important prognostic factors in patients of threatened preterm birth. The objective of this study was to compare the efficacy and safety of magnesium sulfate with that of ritodrine in preterm labor. In this retrospective cohort study, we included patients who were admitted and treated with either ritodrine or magnesium sulfate with the diagnosis of preterm labor at 24-33.6 weeks of gestational age between January 2005 to April 2015. Patients were divided into 2 groups according to the first-used tocolytics (ritodrine group and magnesium sulfate group). We compared the efficacy and prevalence of side effect in each group. The efficacy of both tocolytics was evaluated in terms of preterm delivery within 48 hours, 7 days, or 37 weeks of gestation and need for 2nd line therapy. A total number of 201 patients were enrolled including 177 cases in ritodrine group and 24 cases in magnesium sulfate group. The efficacy of both tocolytics (preterm delivery within 48 hours, 7 days, or 37 weeks of gestation and need for 2nd line therapy) was not different between the 2 groups of cases. In multivariate analysis, gestational age at treatment, twin gestation, intra-amniotic infection and maternal C-reactive protein (CRP) was associated with treatment failure (preterm delivery within 48 hours), but the type of tocolytics was not significantly associated with treatment failure. The type of side effect was different in the 2 groups, but the frequency of total adverse effect, need for discontinuation of therapy because of maternal adverse effect, and severe adverse effect were not different between the two groups of cases.

    Good literary fiction has the potential to move us, extend our sense of life, transform our prospective views and help us in the face of adversity. A neurological disorder is likely to be the most challenging experience a human being may have to confront in a lifetime. As such, literary recreations of illnesses have a doubly powerful effect. Study the synergies between neurology and fictional literature with particular reference to narrative based medicine (NBM). Doctors establish boundaries between the normal and the abnormal. Taking a clinical history is an act of interpretation in which the doctor integrates the science of objective signs and measurable quantities with the art of subjective clinical judgment. The more discrepancy there is between the patient's experience with the illness and the doctor's interpretation of that disease, the less likely the doctor-patient interaction is to succeed. NBM contributes to a better discernment of the meanings, thus considering disease as a biographical event rather than just a natural fact. Drawing from their own experience with disease, writers of fiction provide universal insights through their narratives, whilst neuroscientists, like Cajal, have occasionally devoted their scientific knowledge to literary narratives. Furthermore, neurologists from Alzheimer to Oliver Sacks remind us of the essential value of NBM in the clinic. Integrating NBM (the narrative of patients) and the classic holistic approach to patients with our current paradigm of evidence based medicine represents a challenge as relevant to neurologists as keeping up with technological and scientific advances.

    Background and purpose: To analyze the time course of late rectal- and urinary bladder complications after brachytherapy for cervical cancer and to compare the incidence- and prevalence rates thereof. Patients and methods: A total of 225 patients were treated with external-beam radiotherapy (EBRT) and magnetic resonance imaging (MRI)-guided brachytherapy with or without chemotherapy. Late side effects were assessed prospectively using the Late Effects in Normal Tissue - Subjective, Objective, Management and Analytic (LENT/SOMA) scale. The parameters analyzed were time to onset, duration, actuarial incidence- (occurrence of new side effects during a defined time period) and prevalence rates (side effects existing at a defined time point). Results: Median follow-up was 44 months. Side effects (grade 1-4) in rectum and bladder were present in 31 and 49 patients, 14 and 27 months (mean time to onset) after treatment, respectively. All rectal and 76 % of bladder side effects occurred within 3 years after radiotherapy. Mean duration of rectal events was 19 months; 81 % resolved within 3 years of their initial diagnosis. Mean duration of bladder side effects was 20 months; 61 % resolved within 3 years. The 3- and 5-year actuarial complication rates were 16 and 19 % in rectum and 18 and 28 % in bladder, respectively. The corresponding prevalence rates were 9 and 2 % (rectum) and 18 and 21 % (bladder), respectively. Conclusion: Late side effects after cervical cancer radiotherapy are partially reversible, but their time course is organ-dependent. The combined presentation of incidence- and prevalence rates provides the most comprehensive information. (orig.)
