    Full Text Available Depression is a wide spread disorder. The development of effective pharmacotherapy for major depression is important because it is such a widespread and debilitating mental disorder. The following review is based on the preclinical and clinical studies carried out on Tianeptine, an atypical antidepressant that lowers the adverse effects of stress on brain and memory. It is one of the many drugs being tested these days in the market as nootropics; it is presented as a “Smart Drug”. These are believed to be of low-risk and work to improve, enhance, or repair damage done to the brain via injury or disease.

    Full Text Available Rosacea is a field within dermatology with new insight within immunological research and new treatment-algorithm. Patient education on rosacea and appropriate treatments is an important aspect in helping patients succeed with therapy. Treatment should be tailored to each individual patient, taking into account: symptoms, trigger factors, patients’ wishes, most bothersome symptoms, psychological aspect, individual needs. A combination of clinical therapies to treat different symptoms concomitantly may offer the best possible outcomes for the patient. In this review article we describe these aspects.

    Full Text Available ABSTRACT: Piriformis Syndrome is a cause for Low back pain whi ch is most of the times misdiagnosed as it may mimic with various other con ditions. Abnormal condition of the Piriformis muscle such as hypertrophy, inflammation, or anatomic variations may lead to this condition. Reported incidence rates for Piriformis S yndrome among patients with low back pain vary widely, from 5% to 36%. Etiology of Piriformis Syndrome is also variable. It can be primary due to anatomical problems or secondary due to vario us other causes like trauma, local ischemia, limb-length discrepancy etc. Diagnosis of Piriformis Syndrome is complex. History with various clinical tests along with MRI, EMG (El ectromyography and Diagnostic blocks may help to diagnose this condition. Here is a review of Piriformis syndrome for better understanding of the problem so that the diagnosis a nd management are appropriate. KEY WORDS:Piriformis Syndrome.

  7. [How to write a good clinical review?].

    Krause, B J; Khan, C; Antoch, G

    2015-01-01

    Clinical reviews are an important part of the medical literature offering the reader condensed information on a specific topic. In radiology and nuclear medicine most clinical reviews have a subjective character as they have been written in a rather narrative way. Based on their low level of evidence these narrative reviews are frequently not being considered for establishment of clinical guidelines. The aim of this paper is to aid the reader in writing a good clinical review by highlighting the different aspects of a systematic review.

    Full Text Available Abstract Huntington disease (HD is a rare neurodegenerative disorder of the central nervous system characterized by unwanted choreatic movements, behavioral and psychiatric disturbances and dementia. Prevalence in the Caucasian population is estimated at 1/10,000-1/20,000. Mean age at onset of symptoms is 30-50 years. In some cases symptoms start before the age of 20 years with behavior disturbances and learning difficulties at school (Juvenile Huntington's disease; JHD. The classic sign is chorea that gradually spreads to all muscles. All psychomotor processes become severely retarded. Patients experience psychiatric symptoms and cognitive decline. HD is an autosomal dominant inherited disease caused by an elongated CAG repeat (36 repeats or more on the short arm of chromosome 4p16.3 in the Huntingtine gene. The longer the CAG repeat, the earlier the onset of disease. In cases of JHD the repeat often exceeds 55. Diagnosis is based on clinical symptoms and signs in an individual with a parent with proven HD, and is confirmed by DNA determination. Pre-manifest diagnosis should only be performed by multidisciplinary teams in healthy at-risk adult individuals who want to know whether they carry the mutation or not. Differential diagnoses include other causes of chorea including general internal disorders or iatrogenic disorders. Phenocopies (clinically diagnosed cases of HD without the genetic mutation are observed. Prenatal diagnosis is possible by chorionic villus sampling or amniocentesis. Preimplantation diagnosis with in vitro fertilization is offered in several countries. There is no cure. Management should be multidisciplinary and is based on treating symptoms with a view to improving quality of life. Chorea is treated with dopamine receptor blocking or depleting agents. Medication and non-medical care for depression and aggressive behavior may be required. The progression of the disease leads to a complete dependency in daily life, which

    Full Text Available Aspergillus is a mould which may lead to a variety of infectious, allergic diseases depending on the host's immune status or pulmonary structure. Invasive pulmonary aspergillosis occurs primarily in patients with severe immunodeficiency. The significance of this infection has dramatically increased with growing numbers of patients with impaired immune state associated with the management of malignancy, organ transplantation, autoimmune and inflammatory conditions; critically ill patients and those with chronic obstructive pulmonary disease appear to be at an increased risk. The introduction of new noninvasive tests, combined with more effective and better-tolerated antifungal agents, has resulted in lower mortality rates associated with this infection. Chronic necrotising aspergillosis is a locally invasive disease described in patients with chronic lung disease or mild immunodeficiency. Aspergilloma is usually found in patients with previously formed cavities in the lung, whereas allergic bronchopulmonary aspergillosis, a hypersensitivity reaction to Aspergillus antigens, is generally seen in patients with atopy, asthma or cystic fibrosis. This review provides an update on the evolving epidemiology and risk factors of the major manifestations of Aspergillus lung disease and the clinical manifestations that should prompt the clinician to consider these conditions. Current approaches for the diagnosis and management of these syndromes are discussed.

    1996-12-01

    Lockheed Martin Idaho Technologies Company (LMITCO) used a systems engineering approach to take the first step toward defining a requirements baseline for all indirect work at the Idaho National Engineering Laboratory. The intent of this effort was to define the requirements for indirect work, identify the activities necessary to meet the requirements, and to produce defensible cost estimates for the work. The result of this effort is a scrubbed-down, defensible budget for all indirect work in FY 1997. Buying power for each dollar of direct work was increased by $.02. Recommendations are identified for improvements to this process in FY 1998. The purpose of this report is twofold. First is to report the final results of the 1996 ICRB process, and second is to document the process used such that incremental improvements may be made in future years. Objectives, processes, and approaches are described to provide a trail for future boards. Appendices contain copies of board composition, documentation of the process, as well as the actual training materials.

    Sinnett, Philip Marcus; Carr, Branden; Cook, Gregory; Mucklerath, Halie; Varney, Laura; Weiher, Matt; Yerokhin, Vadim; Vassar, Matt

    2015-01-01

    We examined the use of clinical trials registries in published systematic reviews and meta-analyses from clinical neurology. A review of publications between January 1, 2008 and December 31, 2014 from five neuroscience journals (Annals of Neurology, Brain, Lancet Neurology, Neurology, and The Neuroscientist) was performed to identify eligible systematic reviews. The systematic reviews comprising the final sample were independently appraised to determine if clinical trials registries had been included as part of the search process. Studies acknowledging the use of a trials registry were further examined to determine whether trial data had been incorporated into the analysis. The initial search yielded 194 studies, of which 78 systematic reviews met the selection criteria. Of those, five acknowledged the use of a specific clinical trials registry: four reviewed unpublished trial data and two incorporated unpublished trial data into their results. Based on our sample of systematic reviews, there was no increase in the use of trials registries in systematic review searches over time. Few systematic reviews published in clinical neurology journals included data from relevant clinical trials registries.

    The use of crown lengthening surgery as an adjunct to restorative therapy was first suggested by Rosen and Gitnick. This technique is designed to increase the clinical crown heights of teeth requiring restoration following extensive wear through attrition, abrasion and erosion. This loss of tooth tissue and resulting clinical crown height may be localized to a few teeth or affect the entire dentition. This clinical problem is reflected by the increasing number of reports of treatment of the worn dentition.

  15. A review of clinical guidelines.

    LENUS (Irish Health Repository)

    Andrews, E J

    2012-02-03

    BACKGROUND: Clinical guidelines are increasingly used in patient management but few clinicians are familiar with their origin or appropriate application. METHODS: A Medline search using the terms \\'clinical guidelines\\' and \\'practice guidelines\\' was conducted. Additional references were sourced by manual searching from the bibliographies of articles located. RESULTS AND CONCLUSION: Clinical guidelines originated in the USA in the early 1980s, initially as a cost containment exercise. Significant improvements in the process and outcomes of care have been demonstrated following their introduction, although the extent of improvement varies considerably. The principles for the development of guidelines are well established but many published guidelines fall short of these basic quality criteria. Guidelines are only one aspect of improving quality and should be used within a wider framework of promoting clinical effectiveness. Understanding their limitations as well as their potential benefits should enable clinicians to have a clearer view of their place in everyday practice.

    1991-01-01

    Hemicrania continua (HC) is a headache entity completely responsive to indomethacin. Since 1984, 18 cases have been described, 15 females and 3 males, i.e. a F:M ratio of 5.0. The finding of a female preponderance, like that in chronic paroxysmal hemicrania, is a new observation. HC is, in general, a unilateral headache in the sense that it sets in on one side and subsequently sticks to this side. In two cases, both sides might possibly be involved, when the pain was at its maximum. In another (somewhat dubious) case the headache was bilateral. The pain was continuous from the beginning in 8 of 18 cases (early stage ratio continuous: non-continuous = 0.8). Over time, the headache developed a continuous character in 16 of the 18 cases, producing a "continuous: non-continuous ratio" of 8:1. The intensity of pain generally was moderate and was not reported as excruciatingly severe by any patient. The autonomic involvement from a clinical point of view, was clearly less pronounced than that of other unilateral headaches, such as cluster headache and chronic paroxysmal hemicrania.

    1989-06-01

    The orthodontic journals should provide valid and reliable information that helps clinicians make appropriate decisions about patient care. The nature of the published literature has not been categorized. The American Journal of Orthodontics and Dentofacial Orthopedics (formerly the American Journal of Orthodontics) was reviewed for the years 1976, 1981, and 1986, to determine the frequency of clinical articles, the topics reported, the study designs used to obtain information, the senior author affiliation, and the major funding sources. This review demonstrates that more than half the articles in this Journal report data on patients, with the majority focusing on the evaluation or description of therapeutic interventions. Academic institutions contribute the majority of the clinical research, although only a few student theses are published. The major support for this work continues to be from departmental resources with little external funding. Despite the introduction of powerful research designs such as randomized clinical trials, these methods have not been widely adopted for orthodontic clinical research. The case report (study containing fewer than 10 patients with no control nor comparison group) continues to be the most frequently published format. Clinicians should become aware of the inherent weakness in the research designs generally used and recognize the limited information that can be obtained from such methods. Support for this research needs to be greatly expanded if the more powerful type of study required to provide valid and reliable clinical information is to be continued.

    2015-05-01

    Botulism is a rare neuromuscular condition, and multiple clinical forms are recognized. Infant botulism was first identified in the 1970s, and it typically occurs in infants younger than 1 year of age who ingest Clostridium botulinum spores. A specific treatment for infant botulism, intravenous botulism immunoglobulin (BIG-IV or BabyBIG®), was developed in 2003, and this treatment has substantially decreased both morbidity and hospital costs associated with this illness. This article will review the pathogenesis of infant botulism as well as the epidemiology, clinical manifestations, diagnosis, and treatment of this condition.

    Science.gov (United States)

    Stewart, William C; Adams, Michelle P; Stewart, Jeanette A; Nelson, Lindsay A

    2013-03-01

    The purpose was to evaluate faith-based studies within the medical literature to determine whether there are ways to help physicians understand how religion affects patients’ lives and diseases. We reviewed articles that assessed the influence of religious practices on medicine as a primary or secondary variable in clinical practice. This review evaluated 49 articles and found that religious faith is important to many patients, particularly those with serious disease, and patients depend on it as a positive coping mechanism. The findings of this review can suggest that patients frequently practice religion and interact with God about their disease state. This spiritual interaction may benefit the patient by providing comfort, increasing knowledge about their disease, greater treatment adherence, and quality of life. The results of prayer on specific disease states appear inconsistent with cardiovascular disease but stronger in other disease states.

  6. The Prediabetic Period: Review of Clinical Aspects

    2011-04-01

    Full Text Available Hyperglycemia that does not satisfy the diagnostic criteria for diabetes mellitus (DM is generally called prediabetes (preDM. The global prevalence of preDM has been increasing progressively in the past few decades, and it has been established that preDM status is a strong risk factor for DM and cardiovascular disease. Currently, preDM status is classified into two subtypes: impaired fasting glucose and impaired glucose tolerance. Currently, preDM is not regarded as an independent clinical entity, but only as a risk factor for others. In this article, we review various clinical aspects of preDM in terms of the working definition, changes in criteria over the years, epidemiology, and pathophysiological characteristics, and its clinical significance in current medicine.

    Wren, Tishya A L; Gorton, George E; Ounpuu, Sylvia; Tucker, Carole A

    2011-06-01

    The aim of this systematic review was to evaluate and summarize the current evidence base related to the clinical efficacy of gait analysis. A literature review was conducted to identify references related to human gait analysis published between January 2000 and September 2009 plus relevant older references. The references were assessed independently by four reviewers using a hierarchical model of efficacy adapted for gait analysis, and final scores were agreed upon by at least three of the four reviewers. 1528 references were identified relating to human instrumented gait analysis. Of these, 116 original articles addressed technical accuracy efficacy, 89 addressed diagnostic accuracy efficacy, 11 addressed diagnostic thinking and treatment efficacy, seven addressed patient outcomes efficacy, and one addressed societal efficacy, with some of the articles addressing multiple levels of efficacy. This body of literature provides strong evidence for the technical, diagnostic accuracy, diagnostic thinking and treatment efficacy of gait analysis. The existing evidence also indicates efficacy at the higher levels of patient outcomes and societal cost-effectiveness, but this evidence is more sparse and does not include any randomized controlled trials. Thus, the current evidence supports the clinical efficacy of gait analysis, particularly at the lower levels of efficacy, but additional research is needed to strengthen the evidence base at the higher levels of efficacy.

    Hawker, G A; Stanaitis, I

    2014-12-01

    A systematic search was conducted for the time period April 1 2013 to March 30 2014 using PubMed to identify major osteoarthritis (OA) clinical research themes of the past year. Articles within each theme were selected for inclusion in this review based on study quality and relevance. Two major themes emerged, which relate to the current understanding of OA as a heterogeneous condition with multiple pathogenic mechanisms and clinical manifestations. Theme 1 stems from the role of systemic inflammation in OA pathogenesis, and the concept of 'metabolic OA'. Over the past year, research has examined the effect of OA on incidence and progression of other 'metabolic syndrome'-related conditions, especially cardiovascular disease (CVD) and diabetes and the impact of multi-morbidity on the clinical management of OA. Theme 2 focuses on the concept of personalized medicine as it relates to the treatment of OA. It is hypothesized that the modest efficacy of available OA treatments is a result of inclusion of heterogeneous groups of OA patients in clinical trials. Prognostic studies in the past year have been helpful in identifying 'OA phenotypes' that are more or less likely to respond to treatments--e.g., the presence of synovitis on imaging, central pain sensitization on quantitative sensory testing (QST), or coping efficacy by self-reported patient questionnaire. Their findings are being increasingly used to target interventions to these identified 'OA responder' subgroups with the hopes that treatment effect will be amplified.

    2012-10-01

    Full Text Available Feline leukemia virus (FeLV and feline immunodeficiency virus (FIV are retroviruses with global impact on the health of domestic cats. The two viruses differ in their potential to cause disease. FeLV is more pathogenic, and was long considered to be responsible for more clinical syndromes than any other agent in cats. FeLV can cause tumors (mainly lymphoma, bone marrow suppression syndromes (mainly anemia, and lead to secondary infectious diseases caused by suppressive effects of the virus on bone marrow and the immune system. Today, FeLV is less commonly diagnosed than in the previous 20 years; prevalence has been decreasing in most countries. However, FeLV importance may be underestimated as it has been shown that regressively infected cats (that are negative in routinely used FeLV tests also can develop clinical signs. FIV can cause an acquired immunodeficiency syndrome that increases the risk of opportunistic infections, neurological diseases, and tumors. In most naturally infected cats, however, FIV itself does not cause severe clinical signs, and FIV-infected cats may live many years without any health problems. This article provides a review of clinical syndromes in progressively and regressively FeLV-infected cats as well as in FIV-infected cats.

    Talavera, Juan O; Rivas-Ruiz, Rodolfo

    2012-01-01

    There has been proposed several strategies to select an article under the assumption of quality and relevance. Mostly depend on the presence or absence of a number of features and others, depends of the judgment of other people. However, these strategies do not allow us to know the magnitude of the error contained within each article. And considering that there is not a perfect one, it is important to identify the magnitude of the error and the impact of this in the final result; consequently, it is necessary to develop skills that allow us to review a paper, identify potential errors, and generate a sense of the impact of it over the result. Using the information contained in Clinical Research Series I-VII, we have tried to show its application in a structured review of an article of causality beginning with the revision of the baseline, the maneuver and the outcome, with systematic errors (bias) generated in each section, followed by the appropriate of the statistical test and the sample size used, and finally, the clinical relevance.

    Laura E. Chess

    2016-02-01

    Full Text Available Abstract Background Clinical heterogeneity can be defined as differences in participant characteristics, types or timing of outcome measurements and intervention characteristics. Clinical heterogeneity in systematic reviews has the possibility to significantly affect statistical heterogeneity leading to inaccurate conclusions and misled decision making. The aim of this study is to identify to what extent investigators are assessing clinical heterogeneity in both Cochrane and non-Cochrane systematic reviews. Methods The most recent 100 systematic reviews from the top five journals in medicine—JAMA, Archives of Internal Medicine, British Medical Journal, The Lancet, and PLOS Medicine—and the 100 most recently published and/or updated systematic reviews from Cochrane were collected. Various defined items of clinical heterogeneity were extracted from the included reviews. Investigators used chi-squared tests, logarithmic modeling and linear regressions to determine if the presence of such items served as a predictor for clinical heterogeneity when comparing Cochrane to non-Cochrane reviews. Extracted variables include number of studies, number of participants, presence of quantitative synthesis, exploration of clinical heterogeneity, heterogeneous characteristics explored, basis and methods used for investigating clinical heterogeneity, plotting/visual aids, author contact, inferences from clinical heterogeneity investigation, reporting assessment, and the presence of a priori or post-hoc analysis. Results A total of 317 systematic reviews were considered, of which 199 were in the final analysis. A total of 81 % of Cochrane reviews and 90 % of non-Cochrane reviews explored characteristics that are considered aspects of clinical heterogeneity and also described the methods they planned to use to investigate the influence of those characteristics. Only 1 % of non-Cochrane reviews and 8 % of Cochrane reviews explored the clinical

    Kodiyan, Joyson; Amber, Kyle T

    2015-09-01

    Radiation-induced skin toxicity is the most prevalent side effect of radiation therapy. Not only does it have a significant effect on patients' quality of life, but it also results in poor follow-up and early termination of radiotherapy treatment. Several skin care practices and topical applications have been studied in the field of radiodermatitis, including skin washing, topical steroids, and mechanical skin barriers. Aside from these methods, many patients turn to complementary and alternative medicine for the prevention and treatment of radiodermatitis. Many of these alternative therapies are topically applied antioxidants. While the rationale behind the use of antioxidants in treating radiodermatitis is strong, clinical studies have been far less consistent. Even in large scale randomised controlled trials, findings have been limited by the inconsistent use of topical vehicles and placebos. In this article, the authors review the role of topical antioxidants to better help the practitioner navigate through different available skin directed antioxidants.

  13. Pyridoxine in clinical toxicology: a review.

    Science.gov (United States)

    Lheureux, Philippe; Penaloza, Andrea; Gris, Mireille

    2005-04-01

    Pyridoxine (vitamin B6) is a co-factor in many enzymatic pathways involved in amino acid metabolism: the main biologically active form is pyridoxal 5-phosphate. Pyridoxine has been used as an antidote in acute intoxications, including isoniazid overdose, Gyromitra mushroom or false morrel (monomethylhydrazine) poisoning and hydrazine exposure. It is also recommended as a co-factor to improve the conversion of glyoxylic acid into glycine in ethylene glycol poisoning. Other indications are recommended by some sources (for example crimidine poisoning, zipeprol and theophylline-induced seizures, adjunct to d-penicillamine chelation), without significant supporting data. The value of pyridoxine or its congener metadoxine as an agent for hastening ethanol metabolism or improving vigilance in acute alcohol intoxication is controversial. This paper reviews the various indications of pyridoxine in clinical toxicology and the supporting literature. The potential adverse effects of excessive pyridoxine dosage will also be summarized.

    2013-12-01

    Full Text Available Occupational therapy clinical documentation comprises all recorded information about a client/patient/user, from forwarding to discharge, and it may integrate the patient’s record or serve as support for the exclusive practice of occupational therapy. In Brazil, despite being a mandatory and routine practice, little scientific-technical material on the subject is available for the support of professionals. This study aimed to identify, through literature review, information for greater understanding and support to the practice of professional activity. The data were analyzed and presented according to the different themes identified, seeking common, complementary and divergent points on each theme. Twelve articles were included in the study. The information obtained addressed themes such as registration methods, perception and attitudes of professionals, communication and language, quality, and others. It was possible to achieve a preliminary approach to the subject and have an overview of aspects related to occupational therapy clinical documentation, but some segmented information and several weaknesses were found

  15. Perfectionism as a transdiagnostic process: a clinical review.

    Egan, Sarah J; Wade, Tracey D; Shafran, Roz

    2011-03-01

    Perfectionism is a risk and maintaining factor for eating disorders, anxiety disorders and depression. The objective of this paper is to review the four bodies of evidence supporting the notion that perfectionism is a transdiagnostic process. First, a review of the literature was conducted that demonstrates the elevation of perfectionism across numerous anxiety disorders, depression, and eating disorders compared to healthy controls. Data is presented that shows perfectionism increases vulnerability for eating disorders, and that it maintains obsessive-compulsive disorder, social anxiety and depression as it predicts treatment outcome in these disorders. Second, evidence is examined showing that elevated perfectionism is associated with co-occurrence of psychopathology. Third, the different conceptualisations of perfectionism are reviewed, including a cognitive-behavioural conceptualisation of clinical perfectionism that can be utilised to understand this transdiagnostic process. Fourth, evidence that treatment of perfectionism results in reductions in anxiety, depression and eating pathology is reviewed. Finally, the importance of clinicians considering the routine assessment and treatment of perfectionism is outlined.

  17. Fournier’s gangrene. A clinical review

    Directory of Open Access Journals (Sweden)

    2016-10-01

    Full Text Available Introduction and Hypothesis: Fournier’s gangrene is a rare, necrotising fasciitis of the external genitalia, perineal or perianal regions. The disease has a higher incidence in males and risk factors for development include diabetes, HIV, alcoholism and other immune-compromised states. The aggressive disease process is associated with a high mortality rate of 20-30%. In addition, the increasing age and prevalence of diabetes in the population, begs the need for increased clinical awareness of Fournier’s gangrene with emphasis on early diagnosis and management. This review aims to highlight the relevant research surrounding Fournier’s gangrene, in particular the various prognostic indicators and management strategies. Methods: A search was conducted on the MEDLINE database for all applicable research; clinical reviews, retrospective studies and case reports. In addition to which a search of the European Association of Urology, the British Association for Urological Surgeons and the British Medical Journal was conducted for the most recent recommendations. Results: Immediate broad-spectrum antibiotic therapy and urgent surgical debridement are the core managerial principles of Fournier’s gangrene. The use of adjunctive therapies such as hyperbaric oxygen and vacuum assisted closure are supported in some aspects of the literature and disputed in others. The lack of randomized controlled studies limits the use of these potential additional therapies to patients unresponsive to conventional management. The value of unprocessed honey as a topical antimicrobial agent has been highlighted in the literature for small lesions in uncomplicated patients. Conclusion: Fournier’s gangrene is a urological emergency with a high mortality rate despite advances in the medical and surgical fields. The aggressive nature of the infection advocates the need for early recognition allowing immediate surgical intervention. The opposing results of available

    Amyloidosis consists of different forms of systemic or isolated organ lesions characterised by fibrillary protein deposits in extra-cellular tissue. The isolated involvement of the larynx is the most frequent form in the ENT sphere. We present a clinical case of a 67 year-old woman addressed for a sub-acute laryngitis resistant to conservative treatment, and finally diagnosed with laryngeal amyloidosis. We reviewed its physiopathology, the scientific literature as well as the different possibilities of management. Laryngeal amyloidosis is rare. A thorough additional work-up for the research of multifocal or systemic forms is highly recommended. The treatment aims at a minimal invasive endoscopic surgery with functional organ preservation.

  6. A Clinical and Genetic Review of Aniridia

    Directory of Open Access Journals (Sweden)

    Reza Jafari

    2015-07-01

    Full Text Available Aniridia is a congenital pan-ocular, bilateral disorder. The term aniridia is a misleading misnomer, since at least a rudimentary iris is always present. Varied forms range from almost total absence to only mild hypoplasia of the iris. It is inherent in a number of syndromes, including Wilms tumor Aniridia-Genital anomalies-retardation (WAGR. Aniridia has been shown to be associated with mutations in the PAX6 gene, located on chromosome 11p13, telomeric to the Wilms’ tumor predisposition gene (WT1. The pair box gene 6 (PAX6 situated at 11p13 has been confirmed to be the leading gene associated with aniridia. The PAX6 mutation is present in individuals worldwide and has been studied in Indian, Malaysian, Chinese and Mexican families. Several categories of PAX6 mutations include: nonsense mutations, splicing mutations, frameshift mutations (deletion or insertion, in-frame insertion or deletion, missense mutations and run-on mutations. A novel de novo frameshift mutation in PAX6 most possibly occurred in the paternal gamete. Mutation in PAX6 brings about amino acid substitution for instance proline to glutamine. Deletion of 11p13 involves the PAX6 (aniridia locus and the adjacent WT1 (Wilms tumor locus. Haploinsufficiency at the PAX6 locus brings on aniridia, a pan-ocular eye condition characterized by iris hypoplasia and various other anterior and posterior eye defects, subtle hypogonadotropic hypogonadism and borderline Growth Hormone (GH deficiency. Aniridia may also be affiliated with retinal tears and detachments. Electroretinograms (ERGs done in aniridia illustrate definite retinal dysfunction. Other clinical aspects related to aniridia are ptosis with reduced levator function and anterior polar cataracts. The PAX6 gene mutation was also associated with early-onset diabetes mellitus and aniridia. Aniridia combined with zonular cataract and polydactyly was also described in a patient with Bardet-Biedl syndrome. Aniridia with sensorineural

    This document provides a comprehensive review of Bonneville Power Administration (BPA) funded activities within the Hood River Basin from 1991 to 2001. These activities, known as the Hood River Production Program (HRPP), are intended to mitigate for fish losses related to operation of federal dams in the Columbia River Basin, and to contribute to recovery of endangered and/or threatened salmon and steelhead, as directed by Nation Oceanic and Atmospheric Administration - Fisheries (NOAA Fisheries). The Environmental Impact Statement (EIS) for the HRPP, which authorized BPA to fund salmon and steelhead enhancement activities in the Hood River Basin, was completed in 1996 (BPA 1996). The EIS specified seven years of monitoring and evaluation (1996-2002) after program implementation to determine if program actions needed modification to meet program objectives. The EIS also called for a program review after 2002, that review is reported here.

    Introduction: The clinical examination and other practical clinical skills are fundamental to guide diagnosis and therapy. The teaching of such practical skills has gained significance through legislative changes and adjustments of the curricula of medical schools in Germany. We sought to find out how well final year undergraduate medical students master practical clinical skills. Methods: We conducted a formative 4-station objective structured clinical examination (OSCE) focused on practical clinical skills during the final year of undergraduate medical education. Participation was voluntary. Besides the examination of heart, lungs, abdomen, vascular system, lymphatic system as well as the neurological, endocrinological or orthopaedic examination we assessed other basic clinical skills (e.g. interpretation of an ECG, reading a chest X-ray). Participants filled-out a questionnaire prior to the exam, inter alia to give an estimate of their performance. Results: 214 final year students participated in our study and achieved a mean score of 72.8% of the total score obtainable. 9.3% of participants (n=20) scored insufficiently (clinical skills in the context of a formative assessment. Half of the students over-estimate their own performance. We recommend an institutionalised and frequent assessment of practical clinical skills during undergraduate medical education, especially in the final year. PMID:27579358

    A randomized controlled experimental study of the use x-ray pelvimetry in 151 hospitals in seven PSROs across the United States from June 1977 through March 1982 was conducted. The study was designed to test the impact of a physician educational intervention program on the utilization of a diagnostic procedure of questionable efficacy. Further, special studies were designed to assess substitution and quality effects by measuring changes in the utilization of caesarean section, electronic fetal monitoring and ultrasound; to assess the degree to which justification for the use of pelvimetry is recorded on the patient record; and to measure the utilization of pelvimetry in private radiologists' offices. The report contains a narrative discussion of the PSRO program; ancillary services review; a literature review of studies on the efficacy of pelvimetry and educational intervention strategies; and a detailed discussion of the design, methodology, and findings. The results of the study, a substantive drop in the pelvimetry rate in study hospitals vis-a-vis that in control hospitals pre and postintervention demonstrates that physician practice patterns changed due to the educational intervention.

    Market and technical information on gas fired equipment used in the commercial food service sector in Canada and in each province or territory was presented. Results of a market study and technology review were integrated to establish energy consumption and energy saving potential in this sector. Eight categories of commercial cooking appliances were studied. They were: fryers, griddles, broilers, ranges, ovens, tilting skillets, steam kettles and steamers. Focus was on gas fired appliances, although electric appliances were also included. The total energy consumption of the appliances was estimated at 76,140.37 GBtu in 1994. Gas appliances accounted for 63 per cent of the total inventory and consumed 83 per cent of the total energy used. Cooking energy efficiencies for the gas fired commercial cooking equipment ranged from 10 per cent to 60 per cent. The electric appliances had cooking energy efficiencies ranging from 35 per cent to 95 per cent. A list of recommendations were made for the many opportunities to introduce higher efficiency commercial cooking appliances, essential to slow down or to stabilize the energy consumption of cooking appliances over the next decade. 66 refs., 14 tabs., 18 figs.

    In the era when positron emission tomography (PET) seems to constitute the most advanced application of nuclear medicine imaging, still the conventional procedure of single photon emission computed tomography (SPECT) is far from being obsolete, especially if combined with computed tomography (CT). In fact, this dual modality imaging technique (SPECT/CT) lends itself to a wide variety of useful diagnostic applications whose clinical impact is in most instances already well established, while the evidence is growing for newer applications. The increasing availability of new hybrid SPECT/CT devices with advanced technology offers the opportunity to shorten acquisition time and to provide accurate attenuation correction and fusion imaging. In this review we analyse and discuss the capabilities of SPECT/CT for improving sensitivity and specificity in the imaging of both oncological and non-oncological diseases. The main advantages of SPECT/CT are represented by better attenuation correction, increased specificity, and accurate depiction of the localization of disease and of possible involvement of adjacent tissues. Endocrine and neuroendocrine tumours are accurately localized and characterized by SPECT/CT, as also are solitary pulmonary nodules and lung cancers, brain tumours, lymphoma, prostate cancer, malignant and benign bone lesions, and infection. Furthermore, hybrid SPECT/CT imaging is especially suited to support the increasing applications of minimally invasive surgery, as well as to precisely define the diagnostic and prognostic profile of cardiovascular patients. Finally, the applications of SPECT/CT to other clinical disorders or malignant tumours is currently under extensive investigation, with encouraging results in terms of diagnostic accuracy. (orig.)

  11. Loose connections between peer-reviewed clinical journals and clinical practice.

    Science.gov (United States)

    Haynes, R B

    1990-11-01

    Many important advances in medical care are first reported in the biomedical literature, but physicians find the literature overwhelming and, therefore, are often unaware of advances. This article examines the ways in which peer-reviewed clinical journals contribute to this problem and proposes some solutions for both their editors and clinical readers. Peer-reviewed clinical journals impede the dissemination of validated advances to practitioners by mixing a few rigorous studies (communications from scientists to practitioners) with many preliminary investigations (communications from scientists to scientists). Journals wishing to improve communication with practitioners should feature rigorous studies of the nature, cause, prognosis, diagnosis, prevention, and treatment of disease and should feature sound clinical review articles (communications from practitioners to practitioners). Additional strategies for improving communication between medical scientists and practitioners include improving publication standards for clinical journals, proving more informative abstracts for clinical articles, fostering the development of derivative literature services, and enhancing practitioners' skills in critically appraising the medical literature.

Only one third of the students correctly estimated their performance (35.3%, whereas 30.0% and 18.8% over-estimated their performance by 10% and 20% respectively.Discussion: Final year undergraduate medical students demonstrate considerable deficits performing practical clinical skills in the context of a formative assessment. Half of the students over-estimate their own performance. We recommend an institutionalised and frequent assessment of practical clinical skills during undergraduate medical education, especially in the final year.

    The clinical librarian used a restricted literature searching and quality-filtering approach to provide relevant clinical evidence for the use of cancer molecular biomarkers by institutional policy makers and clinicians in the rapid review process. The librarian-provided evidence was compared with the cited references in the institutional molecular biomarker algorithm. The overall incorporation rate of the librarian-provided references into the algorithm was above 80%. This study suggests the usefulness of clinical librarian expertise for clinical practice. The searching and filtering methods for high-level evidence can be adopted by information professionals who are involved in the rapid literature review.

    Full Text Available Abstract OBJECTIVE This study aimed at analyzing the current state of knowledge on clinical reasoning in undergraduate nursing education. METHODS A systematic scoping review through a search strategy applied to the MEDLINE database, and an analysis of the material recovered by extracting data done by two independent reviewers. The extracted data were analyzed and synthesized in a narrative manner. RESULTS From the 1380 citations retrieved in the search, 23 were kept for review and their contents were summarized into five categories: 1 the experience of developing critical thinking/clinical reasoning/decision-making process; 2 teaching strategies related to the development of critical thinking/clinical reasoning/decision-making process; 3 measurement of variables related to the critical thinking/clinical reasoning/decision-making process; 4 relationship of variables involved in the critical thinking/clinical reasoning/decision-making process; and 5 theoretical development models of critical thinking/clinical reasoning/decision-making process for students. CONCLUSION The biggest challenge for developing knowledge on teaching clinical reasoning seems to be finding consistency between theoretical perspectives on the development of clinical reasoning and methodologies, methods, and procedures in research initiatives in this field.

    Pharmacodynamic studies revealed that 150 mg of roxatidine acetate were optimal in suppressing gastric acid secretion, and that a single bedtime dose of 150 mg was more effective than a dose of 75 mg twice daily in terms of inhibiting nocturnal acid secretion. When administered orally as a capsule containing a granule formulation, the drug displayed modified-release properties, which led to a sustained suppression of gastric acid secretion. Clinical trials revealed that roxatidine acetate, 75 mg twice daily and 150 mg at night, was highly effective in healing duodenal and gastric ulcers and in reducing ulcer pain, over 4, 6, and 8 weeks of therapy. A steady reduction in diameter was observed in those ulcers not completely healed during therapy. The single bedtime dose regimen, while producing the same degree of healing as the divided daily dose during controlled clinical trials, may be of greater value in therapeutic use owing to improved patient compliance. In all efficacy criteria (cure, reduction in ulcer size, and pain relief) there was no significant difference between roxatidine acetate in a total daily dose of 150 mg, ranitidine in a total daily dose of 300 mg, and cimetidine in a total daily dose of 800 mg. Prevention of gastric and duodenal ulcer relapse was achieved by roxatidine acetate, 75 mg at night for 6 months, in about 70% of patients, as determined in open, pilot studies--a rate comparable to those reported for cimetidine and ranitidine. Roxatidine acetate shares with ranitidine an improved safety profile when compared with cimetidine. Human pharmacology studies and short-term and long-term clinical trials have all shown that roxatidine acetate is an exceptionally well tolerated compound, without the antiandrogenic activity and interference with hepatic drug metabolism which have characterized cimetidine treatment. A reason for the improved safety profile of roxatidine acetate may be its greater potency than cimetidine (six times less potent) and

    Melasma is a chronic acquired hypermelanosis of the skin, characterized by irregular brown macules symmetrically distributed on sun-exposed areas of the body, particularly on the face. It is a common cause of demand for dermatological care that affects mainly women (especially during the menacme), and more pigmented phenotypes (Fitzpatrick skin types III-V). Due to its frequent facial involvement, the disease has an impact on the quality of life of patients. Its pathogeny is not yet completely understood, although there are some known triggering factors such as sun exposure, pregnancy, sexual hormones, inflammatory processes of the skin, use of cosmetics, steroids, and photosensitizing drugs. There is also a clear genetic predisposition, since over 40% of patients reported having relatives affected with the disease. In this manuscript, the authors discuss the main clinical and epidemiological aspects of melasma.

  19. The ART approach: clinical aspects reviewed

    Full Text Available The success of ART as a caries management approach is supported by more than 20 years of scientific evidence. ART follows the contemporary concepts of modern cariology and restorative dentistry. It challenges treatment concepts such as step-wise excavation and the need for complete removal of affected dentine. The ART approach so far has mainly used high-viscosity glass-ionomer as the sealant and restorative material. Cariostatic and remineralization properties have been ascribed to this material which requires further research to establish its clinical relevance. The adhesion of high-viscosity glass-ionomer to enamel in pits and fissures is apparently strong, as its remnants, blocking the pits and fissures, have been considered a possible reason for the low prevalence of carious lesion development after the glass-ionomer has clinically disappeared from it. Encapsulated high-viscosity glass-ionomers may lead to higher restoration survival results than those of the hand-mixed version and should, therefore, not be neglected when using ART. Similarly, the use of resin-modified glass-ionomer with ART should be researched. The effectiveness of ART when compared to conventional caries management approaches has been shown in numerous studies. Proper case selection is an important factor for long-lasting ART restoration survival. This is based on the caries risk situation of the individual, the size of the cavity opening, the strategic position of the cavitated tooth and the presence of adequate caries control measures. As the operator is one of the main causes for failure of ART restorations, attending a well-conducted ART training course is mandatory for successful implementation of ART.

    Leadership has been consistently implied in fostering clinical learning. However there is a lack of clarity about the form leadership should take. Limited quantitative research indicated a narrative approach to review literature from a broad perspective. A framework to guide the synthesis was developed to ensure a rigorous review process. Preliminary reading and review of papers using search terms nursing and leadership and clinical learning and learning culture narrowed the inclusion criteria to 245 papers published between 2000 and 2010. Given the diversity of the papers' focus, aim and context, a refined screening process justified the inclusion of twenty-six papers in the review. A critical appraisal of these peer-reviewed quantitative, qualitative and commentary papers identified factors/elements integral to effective leadership. Across the literature leadership was discussed in relation to two broad themes: influence of leadership on organisational learning and development and; influence of leadership on undergraduate clinical education. The factors central to leadership emerged as transformative principles, the role of the nurse unit/ward manager, collaboration and relationship building and role-modelling. The review has raised some suggestions for future research aimed at examining the impact of a leadership capacity building intervention that supports clinical learning.

    trauma (HT) of varying severity, and cognitive disorders of different causes. In studies conducted in the treatment of patients with HT, citicoline was able to accelerate recovery from post-traumatic coma and neurological deficits, achieving an improved final functional outcome, and to shorten hospital stay in these patients. Citicoline also improved the mnesic and cognitive disorders seen after HT of minor severity that constitute the so-called post-concussional syndrome. In the treatment of patients with acute ischemic cerebral vascular disease, citicoline accelerates recovery of consciousness and motor deficit, achieves a better final outcome, and facilitates rehabilitation of these patients. The other major indication of citicoline is for treatment of senile cognitive impairment, either secondary to degenerative diseases (e.g. Alzheimer disease) or to chronic cerebral vascular disease. In patients with chronic cerebral ischemia, citicoline improves scores in cognitive rating scales, while in patients with senile dementia of the Alzheimer type it stops the course of disease, and neuroendocrine, neuroimmunomodulatory, and neurophysiological benefits have been reported. Citicoline has also been shown to be effective in Parkinson disease, drug addictions, and alcoholism, as well as in amblyopia and glaucoma. No serious side effects have occurred in any series of patients treated with citicoline, which attests to the safety of treatment with citicoline.

    2016-01-01

    Abstract Hypoxic hepatitis (HH), also known as ischemic hepatitis or shock liver, is characterized by a massive, rapid rise in serum aminotransferases resulting from reduced oxygen delivery to the liver. The most common predisposing condition is cardiac failure, followed by circulatory failure as occurs in septic shock and respiratory failure. HH does, however, occur in the absence of a documented hypotensive event or shock state in 50% of patients. In intensive care units, the incidence of HH is near 2.5%, but has been reported as high as 10% in some studies. The pathophysiology is multifactorial, but often involves hepatic congestion from right heart failure along with reduced hepatic blood flow, total body hypoxemia, reduced oxygen uptake by hepatocytes or reperfusion injury following ischemia. The diagnosis is primarily clinical, and typically does not require liver biopsy. The definitive treatment of HH involves correction of the underlying disease state, but successful management includes monitoring for the potential complications such as hypoglycemia, hyperglycemia, hyperammonemia and hepatopulmonary syndrome. Prognosis of HH remains poor, especially for cases in which there was a delay in diagnosis. The in-hospital mortality rate is >50%, and the most frequent cause of death is the predisposing condition and not the liver injury itself. PMID:27777895

    Full Text Available Diabetes insipidus (DI is a complex disease. DI is inability of the body to conserve water. Polydipsia and polyuria are the major manifestations of DI. DI has various variants including central diabetes insipidus (due to defect in ADH secretion, nephrogenic diabetes insipidus (due to defect in ADH receptors or urea receptors, gestational diabetes insipidus (due to catabolism of ADH by placental vasopressinase and primary polydipsia (due to massive fluid intake. The cause of various variants of DI is either acquired or congenital. High plasma osmolality due to hypotonic urine excretion can be fatal because it can cause psychosis, lethargy, seizures, coma or even death. Polyuria and polydipsia help in the diagnosis of DI. Differential diagnosis of various variants of DI can be carried out on the basis of water deprivation test, MRI and other radiological techniques. The proper management of DI is the replenishment of water loss and correction of clinical presentations produced as a result of DI, major is hypernatremia. The best management for primary polydipsia is fluid restriction while fluid intake is used for adipsic diabetes insipidus. ADH replacement therapy is widely used to treat DI. DDAVP or desmopressin is mostly preferred ADH analogue because it has less side effects and resistant to placental vasoprssinase. [Int J Res Med Sci 2016; 4(1.000: 5-11

  4. Review of splanchnic oximetry in clinical medicine

    Global tissue perfusion and oxygenation are important indicators of physiologic function in humans. The monitoring of splanchnic oximetry through the use of near-infrared spectroscopy (NIRS) is an emerging method used to assess tissue oxygenation status. Splanchnic tissue oxygenation (SrS) is thought to be potentially of high value in critically ill patients because gastrointestinal organs can often be the first to suffer ischemic injury. During conditions of hypovolemia, cardiac dysfunction, or decreased oxygen-carrying capacity, blood flow is diverted toward vital organs, such as the brain and the heart at the expense of the splanchnic circulation. While monitoring SrS has great potential benefit, there are limitations to the technology and techniques. SrS has been found to have a relatively high degree of variability that can potentially make it difficult to interpret. In addition, because splanchnic organs only lie near the skin surface in children and infants, and energy from currently available sensors only penetrates a few centimeters deep, it can be difficult to use clinically in a noninvasive manner in adults. Research thus far is showing that splanchnic oximetry holds great promise in the ability to monitor patient oxygenation status and detect disease states in humans, especially in pediatric populations.

    Postural orthostatic tachycardia syndrome was defined in adult patients as an increase >30 beats per minute in heart rate of a symptomatic patient when moving from supine to upright position. Clinical signs may include postural tachycardia, headache, abdominal discomfort, dizziness/presyncope, nausea, and fatigue. The most common adolescent presentation involves teenagers within 1-3 years of their growth spurt who, after a period of inactivity from illness or injury, cannot return to normal activity levels because of symptoms induced by upright posture. Postural orthostatic tachycardia syndrome is complex and likely has numerous, concurrent pathophysiologic etiologies, presenting along a wide spectrum of potential symptoms. Nonpharmacologic treatment includes (1) increasing aerobic exercise, (2) lower-extremity strengthening, (3) increasing fluid/salt intake, (4) psychophysiologic training for management of pain/anxiety, and (5) family education. Pharmacologic treatment is recommended on a case-by-case basis, and can include beta-blocking agents to blunt orthostatic increases in heart rate, alpha-adrenergic agents to increase peripheral vascular resistance, mineralocorticoid agents to increase blood volume, and serotonin reuptake inhibitors. An interdisciplinary research approach may determine mechanistic root causes of symptoms, and is investigating novel management plans for affected patients.

    Resistant hypertension(RHTN) is a commonly encountered clinical problem and its management remains a challenging task for healthcare providers. The prevalence of true RHTN has been difficult to assess due to pseudoresistance and secondary hypertension. Atherosclerotic renal artery stenosis(RAS) has been associated as a secondary cause of RHTN. Initial studies had shown that angioplasty and stenting for RAS were a promising therapeutic option when added to optimal medical management. However, recent randomized controlled trials in larger populations have failed to show any such benefit. Sympathetic autonomic nervous system dysfunction is commonly noted in individuals with resistant hypertension. Surgical sympathectomy was the treatment of choice for malignant hypertension and it significantly improved mortality. However, postsurgical complications and the advent of antihypertensive drugs made this approach less desirable and it was eventually abandoned. Increasing prevalence of RHTN in recent decades has led to the emergence of minimally invasive interventions such as transcatheter renal denervation for better control of blood pressure. It is a minimally invasive procedure which uses radiofrequency energy for selective ablation of renal sympathetic nerves located in the adventitia of the renal artery. It is a quick procedure and has a short recovery time. Early studies in small population showed significant reduction in blood pressure. The most recent Symplicity HTN-3 study, which is the largest randomized control trial and the only one to use a sham procedure in controls, failed to show significant BP reduction at 6 mo.

    Full Text Available Joanne Porter, Julia Morphet, Karen Missen, Anita Raymond School of Nursing and Midwifery, Monash University, Churchill, VIC, Australia Aim: To measure final-year nursing students’ preparation for high-acuity placement with emphasis on clinical skill performance confidence. Background: Self-confidence has been reported as being a key component for effective clinical performance, and confident students are more likely to be more effective nurses. Clinical skill performance is reported to be the most influential source of self-confidence. Student preparation and skill acquisition are therefore important aspects in ensuring students have successful clinical placements, especially in areas of high acuity. Curriculum development should aim to assist students with their theoretical and clinical preparedness for the clinical environment. Method: A modified pretest/posttest survey design was used to measure the confidence of third-year undergraduate nursing students (n = 318 for placement into a high-acuity clinical setting. The survey comprised four questions related to clinical placement and prospect of participating in a cardiac arrest scenario, and confidence rating levels of skills related to practice in a high-acuity setting. Content and face validity were established by an expert panel (α = 0.90 and reliability was established by the pilot study in 2009. Comparisons were made between confidence levels at the beginning and end of semester. Results: Student confidence to perform individual clinical skills increased over the semester; however their feelings of preparedness for high-acuity clinical placement decreased over the same time period. Reported confidence levels improved with further exposure to clinical placement. Conclusion: There may be many external factors that influence students’ perceptions of confidence and preparedness for practice. Further research is recommended to identify causes of poor self-confidence in final-year nursing

  9. Feline heartworm disease: a clinical review.

    Litster, Annette L; Atwell, Richard B

    2008-04-01

    Feline heartworm disease is caused by the filarial nematode Dirofilaria immitis, and is transmitted by mosquitoes in heartworm-endemic areas worldwide. While dogs are the definitive hosts for this parasite, cats can also be infected, and the overall prevalence in cats is between 5% and 10% of that in dogs in any given area. The spectrum of feline presentations varies from asymptomatic infections to chronic respiratory signs, sometimes accompanied by chronic vomiting to acute death with no premonitory signs. Ante-mortem diagnosis can be challenging and relies on a combination of tests, including antigen and antibody serology, thoracic radiography and echocardiography. As treatment with heartworm adulticidal drugs can be life-threatening and heartworm infection in cats is often self-limiting, infected cats are frequently managed with supportive treatment (corticosteroids, bronchodilators, and anti-emetics). Surgical removal of filariae using extraction devices may be considered in some acute cases where immediate curative treatment is necessary, but filarial breakage during the procedure may result in an acute fatal shock-like reaction. Necropsy findings are mainly pulmonary and include muscular hypertrophy of the pulmonary arteries and arterioles on histopathology. A number of safe and effective macrocytic lactone drugs are available for prophylaxis in cats. These drugs can kill a range of larval and adult life-cycle stage heartworms, which may be advantageous in cases of owner compliance failure or when heartworm infection status is undetermined at the time prophylaxis is commenced. An index of suspicion for feline heartworm disease is warranted in unprotected cats with respiratory signs, and perhaps chronic vomiting, in areas where canine heartworm disease is endemic. Many cats, once diagnosed and with appropriate supportive care and monitoring, will resolve their infection and be free of clinical signs.

    Failure to initiate or intensify therapy according to evidence-based guidelines is increasingly being acknowledged as a phenomenon that contributes to inadequate management of chronic conditions, and is referred to as clinical inertia. However, the number and complexity of factors associated with the clinical reasoning that underlies the decision-making processes in medicine calls for a critical examination of the consistency of the concept. Indeed, in the absence of information on and justification of treatment decisions that were made, clinical inertia may be only apparent, and actually reflect good clinical practice. This integrative review seeks to address the factors generally associated with clinical inaction, in order to better delineate the concept of true clinical inertia. PMID:24868181

    Connective tissue manipulation or connective tissue massage (bindegewebsmassage) is a manual reflex therapy in that it is applied with the therapist's hands which are in contact with the patient's skin. The assessment of the patient and the clinical decision-making that directs treatment is based on a theoretical model that assumes a reflex effect on the autonomic nervous system which is induced by manipulating the fascial layers within and beneath the skin to stimulate cutaneo-visceral reflexes. This paper reviews the literature and current research findings to establish the theoretical framework for CTM and the evidence for its clinical effects. The rationale for the principles of treatment are discussed and the evidence for the clinical effectiveness assessed through an analytical review of the clinical research.

It commonly affects the deep leg veins (such as the calf veins, femoral vein, or popliteal vein or the deep veins of the pelvis. It is a potentially dangerous condition that can lead to preventable morbidity and mortality.Aim: To present an update on the causes and management of DVT.Methods: A review of publications obtained from Medline search, medical libraries, and Google.Results: DVT affects 0.1% of persons per year. It is predominantly a disease of the elderly and has a slight male preponderance. The approach to making a diagnosis currently involves an algorithm combining pretest probability, D-dimer testing, and compression ultrasonography. This will guide further investigations if necessary. Prophylaxis is both mechanical and pharmacological. The goals of treatment are to prevent extension of thrombi, pulmonary embolism, recurrence of thrombi, and the development of complications such as pulmonary hypertension and post-thrombotic syndrome.Conclusion: DVT is a potentially dangerous condition with a myriad of risk factors. Prophylaxis is very important and can be mechanical and pharmacological. The mainstay of treatment is anticoagulant therapy. Low-molecular-weight heparin, unfractionated heparin, and vitamin K antagonists have been the treatment of choice. Currently anticoagulants specifically targeting components of the common pathway have been recommended for prophylaxis. These include fondaparinux, a selective indirect factor Xa inhibitor and the new oral selective direct thrombin inhibitors (dabigatran and selective

    Ischaemic stroke clinical outcomes are improved by earlier treatment with intravenous thrombolysis. An existing pathway at the Mater University Hospital for assessment of suspected acute stroke in the Emergency Department was updated, aiming to shorten ‘door to needle time’. This study examines the final clinical diagnosis of Dublin Fire Brigade Ambulance Paramedic identified Face Arm Speech Test (FAST) positive patients presenting to the Emergency Department over a 7 month period. A retrospective analysis was carried out of 177 consecutive FAST positive patients presenting between March and November 2014. The final clinical diagnosis was acute stroke in 57.1% (n=101) of patients. Of these, 76 were ischaemic strokes of whom 56.5% (n=43) were thrombolysed. In the pre-hospital setting Ambulance Paramedics can identify, with reasonable accuracy, acute stroke using the FAST test. Over half of the ischaemic stroke patients presenting via this pathway can be treated with intravenous thrombolysis

  15. Systematic reviews, systematic error and the acquisition of clinical knowledge

    2010-06-01

    Full Text Available Abstract Background Since its inception, evidence-based medicine and its application through systematic reviews, has been widely accepted. However, it has also been strongly criticised and resisted by some academic groups and clinicians. One of the main criticisms of evidence-based medicine is that it appears to claim to have unique access to absolute scientific truth and thus devalues and replaces other types of knowledge sources. Discussion The various types of clinical knowledge sources are categorised on the basis of Kant's categories of knowledge acquisition, as being either 'analytic' or 'synthetic'. It is shown that these categories do not act in opposition but rather, depend upon each other. The unity of analysis and synthesis in knowledge acquisition is demonstrated during the process of systematic reviewing of clinical trials. Systematic reviews constitute comprehensive synthesis of clinical knowledge but depend upon plausible, analytical hypothesis development for the trials reviewed. The dangers of systematic error regarding the internal validity of acquired knowledge are highlighted on the basis of empirical evidence. It has been shown that the systematic review process reduces systematic error, thus ensuring high internal validity. It is argued that this process does not exclude other types of knowledge sources. Instead, amongst these other types it functions as an integrated element during the acquisition of clinical knowledge. Conclusions The acquisition of clinical knowledge is based on interaction between analysis and synthesis. Systematic reviews provide the highest form of synthetic knowledge acquisition in terms of achieving internal validity of results. In that capacity it informs the analytic knowledge of the clinician but does not replace it.

    Full Text Available Abstract Background The General Medical Council states that teaching doctors and students is important for the care of patients. Our aim was to deliver a structured teaching program to final year medical students, evaluate the efficacy of teaching given by junior doctors and review the pertinent literature. Methods We developed a revision package for final year medical students sitting the Objective Structured Clinical Examination (OSCE. The package was created and delivered exclusively by recent medical graduates and consisted of lectures and small group seminars covering the core areas of medicine and surgery, with a focus on specific OSCE station examples. Students were asked to complete a feedback questionnaire during and immediately after the program. Results One hundred and eighteen completed feedback questionnaires were analysed. All participants stated that the content covered was relevant to their revision. 73.2% stated that junior doctors delivered teaching that is comparable to that of consultant - led teaching. 97.9% stated the revision course had a positive influence on their learning. Conclusions Our study showed that recent medical graduates are able to create and deliver a structured, formal revision program and provide a unique perspective to exam preparation that was very well received by our student cohort. The role of junior doctors teaching medical students in a formal structured environment is very valuable and should be encouraged.

    Carter, Helen; Goodwin, Sarah

    This article examines the importance of clinical reviews for people receiving care in custodial settings. A case study is used to illustrate the need for accurate record-keeping, particularly following death. Healthcare professionals have a duty to ensure that prisoners have the same rights as members of the general public in relation to access to health care and opportunities to improve their health.

  19. Public titles of clinical trials should have ethics review.

    Saenz, Carla; Reveiz, Ludovic; Tisdale, John F

    2015-09-01

    A key aspect to guarantee that research with human subjects is ethical is being overlooked. Ethics review committees invest great effort examining the informed consent documents of research protocols to ensure that potential participants can provide consent validly and are not deluded into thinking that the experimental intervention they may sign up for is already known to be therapeutic. However, these efforts to avoid what is called the "therapeutic misconception" might be in vain if the title with which the studies are being introduced to the potential participants escapes ethics review. Research participants might be deceived by clinical trials entitled "novel therapy" when the point of the trial is precisely to find out whether the intervention at stake is therapeutic or not. Providing potential research participants with such misleading information hampers their ability to make informed decisions. The well-established scrutiny that ethics review committees exercise with regard to consent forms is limited if the registration of clinical trials, for which a public title is chosen, constitutes a process that is independent from the ethics review. In this article, we examine this problem, assess recent measures to integrate clinical trial registration with ethics review processes, and provide specific recommendations to solve the problem and ultimately enhance the accountability, transparency, and ethics of research with human subjects.

However, the number and complexity of factors associated with the clinical reasoning that underlies the decision-making processes in medicine calls for a critical examination of the consistency of the concept. Indeed, in the absence of information on and justification of treatment decisions that were made, clinical inertia may be only apparent, and actually reflect good clinical practice. This integrative review seeks to address the factors generally associated with clinical inaction, in order to better delineate the concept of true clinical inertia.

    Shivanand Kattimani

    2013-01-01

    Full Text Available Alcohol withdrawal is commonly encountered in general hospital settings. It forms a major part of referrals received by a consultation-liaison psychiatrist. This article aims to review the evidence base for appropriate clinical management of the alcohol withdrawal syndrome. We searched Pubmed for articles published in English on pharmacological management of alcohol withdrawal in humans with no limit on the date of publication. Articles not relevant to clinical management were excluded based on the titles and abstract available. Full-text articles were obtained from this list and the cross-references. There were four meta-analyses, 9 systematic reviews, 26 review articles and other type of publications like textbooks. Alcohol withdrawal syndrome is a clinical diagnosis. It may vary in severity. Complicated alcohol withdrawal presents with hallucinations, seizures or delirium tremens. Benzodiazepines have the best evidence base in the treatment of alcohol withdrawal, followed by anticonvulsants. Clinical institutes withdrawal assessment-alcohol revised is useful with pitfalls in patients with medical comorbidities. Evidence favors an approach of symptom-monitored loading for severe withdrawals where an initial dose is guided by risk factors for complicated withdrawals and further dosing may be guided by withdrawal severity. Supportive care and use of vitamins is also discussed.

    2015-01-01

    The interoperability of Clinical Decision Support (CDS) systems with other health information systems has become one of the main limitations to their broad adoption. Semantic interoperability must be granted in order to share CDS modules across different health information systems. Currently, numerous standards for different purposes are available to enable the interoperability of CDS systems. We performed a literature review to identify and provide an overview of the available standards that enable CDS interoperability in the areas of clinical information, decision logic, terminology, and web service interfaces.

    Heparin-induced thrombocytopenia is a profoundly dangerous, potentially lethal, immunologically mediated adverse drug reaction to unfractionated heparin or, less commonly, to low-molecular weight heparin. In this comprehensive review, the authors highlight heparin-induced thrombocytopenia's risk factors, clinical presentation, pathophysiology, diagnostic principles, and treatment. The authors place special emphasis on the management of patients requiring procedures using cardiopulmonary bypass or interventions in the catheterization laboratory. Clinical vigilance of this disease process is important to ensure its recognition, diagnosis, and treatment. Misdiagnosis of the syndrome, as well as misunderstanding of the disease process, continues to contribute to its morbidity and mortality.

The available literature has been reviewed for motor, cognitive, and psychiatric alterations, which are the three major symptom domains of this devastating progressive disease. From a clinical point of view, one has to be aware that the HD phenotype can vary highly across individuals and during the course of the disease. Also, symptoms in juvenile HD can differ substantially from those with adult-onset of HD. Although there is no cure of HD and management is limited, motor and psychiatric symptoms often respond to pharmacotherapy, and nonpharmacological approaches as well as supportive care are essential. International treatment recommendations based on study results, critical statements, and expert opinions have been included. This review is restricted to symptomatic and supportive approaches since all attempts to establish a cure for the disease or modifying therapies have failed so far.

    Edirippulige, S; Armfield, N R

    2017-02-01

    Introduction Despite a growing literature base, substantial investment, and policy changes within governments, the integration of telehealth into routine clinical care has been limited. The availability of appropriate systematic education and training for practitioners has been highlighted as necessary for strong adoption. However, the availability and nature of telehealth-related education and training for practitioners is not understood. By reviewing the literature, we aimed to describe the delivery of education and training in telehealth, with particular focus on content, modes of delivery, types of institutions, and target clinician groups. Methods We performed searches using PubMed, Scopus, Embase, Web of Science, PsycINFO, the Cochrane Library, and ERIC. We included studies that were focused on the delivery of telehealth-related academic or vocational education and training. We extracted information pertaining to country, programs and their participants, and tabulated the results. Results Altogether 388 articles were identified, of which nine studies were selected for final review. Programs from five countries were represented and articles were spread across telemedicine and clinically oriented journals. Education and training in telehealth has been provided as both university level and vocational courses using conventional classroom based delivery methods and e-learning. Reported curriculum items included terminology, clinical applications, the evidence-base, and technological aspects. Conclusions Published evidence in peer-reviewed literature on telehealth education and training is limited. According to this review, a number of topics relating to telehealth have been covered by existing education programs both within tertiary and professional development levels.

  18. Clinical observed performance evaluation: a prospective study in final year students of surgery.

    LENUS (Irish Health Repository)

    Markey, G C

    2010-06-24

    We report a prospective study of clinical observed performance evaluation (COPE) for 197 medical students in the pre-qualification year of clinical education. Psychometric quality was the main endpoint. Students were assessed in groups of 5 in 40-min patient encounters, with each student the focus of evaluation for 8 min. Each student had a series of assessments in a 25-week teaching programme. Over time, several clinicians from a pool of 16 surgical consultants and registrars evaluated each student by direct observation. A structured rating form was used for assessment data. Variance component analysis (VCA), internal consistency and inter-rater agreement were used to estimate reliability. The predictive and convergent validity of COPE in relation to summative OSCE, long case, and overall final examination was estimated. Median number of COPE assessments per student was 7. Generalisability of a mean score over 7 COPE assessments was 0.66, equal to that of an 8 x 7.5 min station final OSCE. Internal consistency was 0.88-0.97 and inter-rater agreement 0.82. Significant correlations were observed with OSCE performance (R = 0.55 disattenuated) and long case (R = 0.47 disattenuated). Convergent validity was 0.81 by VCA. Overall final examination performance was linearly related to mean COPE score with standard error 3.7%. COPE permitted efficient serial assessment of a large cohort of final year students in a real world setting. Its psychometric quality compared well with conventional assessments and with other direct observation instruments as reported in the literature. Effect on learning, and translation to clinical care, are directions for future research.

  20. Statistical challenges for central monitoring in clinical trials: a review.

    Science.gov (United States)

    Oba, Koji

    2016-02-01

    Recently, the complexity and costs of clinical trials have increased dramatically, especially in the area of new drug development. Risk-based monitoring (RBM) has been attracting attention as an efficient and effective trial monitoring approach, which can be applied irrespectively of the trial sponsor, i.e., academic institution or pharmaceutical company. In the RBM paradigm, it is expected that a statistical approach to central monitoring can help improve the effectiveness of on-site monitoring by prioritizing and guiding site visits according to central statistical data checks, as evidenced by examples of actual trial datasets. In this review, several statistical methods for central monitoring are presented. It is important to share knowledge about the role and performance capabilities of statistical methodology among clinical trial team members (i.e., sponsors, investigators, data managers, monitors, and biostatisticians) in order to adopt central statistical monitoring for assessing data quality in the actual clinical trial.

  1. E-textiles in Clinical Rehabilitation: A Scoping Review

    Directory of Open Access Journals (Sweden)

    Amanda Fleury

    2015-02-01

    Full Text Available Electronic textiles have potential for many practical uses in clinical rehabilitation. This scoping review appraises recent and emerging developments of textile-based sensors with applications to rehabilitation. Contributions published from 2009 to 2013 are appraised with a specific focus on the measured physiological or biomechanical phenomenon, current measurement practices, textile innovations, and their merits and limitations. While fabric-based signal quality and sensor integration have advanced considerably, overall system integration (including circuitry and power has not been fully realized. Validation against clinical gold standards is inconsistent at best, and feasibility with clinical populations remains to be demonstrated. The overwhelming focus of research and development has been on remote sensing but the opportunity for textile-mediated feedback to the wearer remains unexplored. Recommendations for future research are provided.

  2. Learning from clinical placement experience: Analysing nursing students' final reflections in a digital storytelling activity.

    Science.gov (United States)

    Paliadelis, Penny; Wood, Pamela

    2016-09-01

    This paper reports on the learning potential of a reflective activity undertaken by final year nursing students, in which they were asked to recount two meaningful events that occurred during their clinical placements over the duration of their 3-year nursing degree program and reflect on how these events contributed to their learning to become beginning level Registered Nurses (RNs). This descriptive qualitative study gathered narratives from 92 students as individual postings in an online forum created within the University's learning management system. An analysis of the students' reflections are the focus of this paper particularly in relation to the value of reflecting on the identified events. Four themes emerged that clearly highlight the way in which these students interpreted and learned from both positive and negative clinical experiences, their strong desire to fit into their new role and their ability to re-imagine how they might respond to clinical events when they become Registered Nurses. The findings of this study may contribute to developing nursing curricula that better prepares final year students for the realities of practice.

  4. Review of Positive Psychology Applications in Clinical Medical Populations.

    Science.gov (United States)

    Macaskill, Ann

    2016-09-07

    This review examines the application of positive psychology concepts in physical health care contexts. Positive psychology aims to promote well-being in the general population. Studies identifying character strengths associated with well-being in healthy populations are numerous. Such strengths have been classified and Positive Psychology Interventions (PPIs) have been created to further develop these strengths in individuals. Positive psychology research is increasingly being undertaken in health care contexts. The review identified that most of this research involves measuring character strengths and their association with health outcomes in patients with a range of different conditions, similar to the position in positive psychology research on non-clinical populations. More recently, PPIs are beginning to be applied to clinical populations with physical health problems and this research, although relatively scarce, is reviewed here for cancer, coronary heart disease, and diabetes. In common with PPIs being evaluated in the general population, high quality studies are scarce. Applying PPIs to patients with serious health conditions presents significant challenges to health psychologists. They must ensure that patients are dealt with appropriately and ethically, given that exaggerated claims for PPIs are made on the internet quite frequently. This is discussed along with the need for more high quality research.

    2016-04-21

    The World Health Organization's Global Influenza Surveillance and Response System meets twice a year to generate a recommendation for the composition of the seasonal influenza vaccine. Interim vaccine effectiveness (VE) estimates provide a preliminary indication of influenza vaccine performance during the season and may be useful for decision making. We reviewed 17 pairs of studies reporting 33 pairs of interim and final estimates using the test-negative design to evaluate whether interim estimates can reliably predict final estimates. We examined features of the study design that may be correlated with interim estimates being substantially different from their final estimates and identified differences related to change in study period and concomitant changes in sample size, proportion vaccinated and proportion of cases. An absolute difference of no more than 10% between interim and final estimates was found for 18 of 33 reported pairs of estimates, including six of 12 pairs reporting VE against any influenza, six of 10 for influenza A(H1N1)pdm09, four of seven for influenza A(H3N2) and two of four for influenza B. While we identified inconsistencies in the methods, the similarities between interim and final estimates support the utility of generating and disseminating preliminary estimates of VE while virus circulation is ongoing.

  6. Pouchitis: an evolving clinical enigma--a review.

    LENUS (Irish Health Repository)

    Coffey, John Calvin

    2009-01-01

    While the overall incidence of pouchitis is low, extensive research continues at clinical and experimental levels in attempts to unravel its etiology. The ileal pouch and pouchitis together represent a unique in vivo opportunity to study mucosal adaptation and inflammation in depth. In the recent past, molecular data relating to pouchitis has significantly expanded. These data provide invaluable insight into intracellular and extracellular events that underpin mucosal adaptation and inflammation. Advances in classification, risk factor evaluation, and prevention have meant that a review of this data, as well as its relationship to our current understanding of pouchitis, is both timely and warranted. Therefore, the aim of this review is to summarize recent data in the context of the established literature.

  7. Clinical uses of the medicinal leech: A practical review

    Directory of Open Access Journals (Sweden)

    B S Porshinsky

    2011-01-01

    Full Text Available The medicinal leech, Hirudo medicinalis, is an excellent example of the use of invertebrates in the treatment of human disease. Utilized for various medical indications since the ancient times, the medicinal leech is currently being used in a narrow range of well-defined and scientifically-grounded clinical applications. Hirudotherapy is most commonly used in the setting of venous congestion associated with soft tissue replantations and free flap-based reconstructive surgery. This is a comprehensive review of current clinical applications of hirudotherapy, featuring a comprehensive search of all major medical search engines (i.e. PubMed, Google Scholar, ScientificCommons and other cross-referenced sources. The authors focus on indications, contraindications, practical application/handling of the leech, and therapy-related complications.

  8. Cannabinoids and Dementia: A Review of Clinical and Preclinical Data

    Directory of Open Access Journals (Sweden)

    Michael Halpern

    2010-08-01

    Full Text Available The endocannabinoid system has been shown to be associated with neurodegenerative diseases and dementia. We review the preclinical and clinical data on cannabinoids and four neurodegenerative diseases: Alzheimer’s disease (AD, Huntington’s disease (HD, Parkinson’s disease (PD and vascular dementia (VD. Numerous studies have demonstrated an involvement of the cannabinoid system in neurotransmission, neuropathology and neurobiology of dementias. In addition, several candidate compounds have demonstrated efficacy in vitro. However, some of the substances produced inconclusive results in vivo. Therefore, only few trials have aimed to replicate the effects seen in animal studies in patients. Indeed, the literature on cannabinoid administration in patients is scarce. While preclinical findings suggest causal treatment strategies involving cannabinoids, clinical trials have only assessed the suitability of cannabinoid receptor agonists, antagonists and cannabidiol for the symptomatic treatment of dementia. Further research is needed, including in vivo models of dementia and human studies.

  9. Operating room use of hypertonic solutions: a clinical review

    Directory of Open Access Journals (Sweden)

    Gustavo Azoubel

    2008-01-01

    Full Text Available Hyperosmotic-hyperoncotic solutions have been widely used during prehospital care of trauma patients and have shown positive hemodynamic effects. Recently, there has been a growing interest in intra-operative use of hypertonic solutions. We reviewed 30 clinical studies on the use of hypertonic saline solutions during surgeries, with the majority being cardiac surgeries. Reduced positive fluid balance, increased cardiac index, and decreased systemic vascular resistance were the main beneficial effects of using hypertonic solutions in this population. Well-designed clinical trials are highly needed, particularly in aortic aneurysm repair surgeries, where hypertonic solutions have shown many beneficial effects. Examining the immunomodulatory effects of hypertonic solutions should also be a priority in future studies.

    Full Text Available Aloe vera has been used for over five thousand years. Throughout history, it has been considered a magical plant, almost a panacea, capable of remedying many of mankind’s ailments. It is only in the last 20 years, after a series of proven research, that we can highlight the characteristics of this plant, whose secrets have been hidden behind a blanket of botanical and pharmacological puzzles that only today begin to yield some answers. The Aloe vera plant and its clinical uses are briefly reviewed in this article.

    Hands-on healing and energy-based interventions have been found in cultures throughout history around the world. These complementary therapies, rooted in ancient Eastern healing practices, are becoming mainstream. Healing Touch, a biofield therapy that arose in the nursing field in the late 1980s, is used in a variety of settings (i.e., pain centers, surgical settings, and private practices) with reported benefits (i.e., decreased anxiety, pain, and depressive behaviors; increased relaxation and a sense of well-being). However, clinical trial data concerning the effectiveness of Healing Touch have not been evaluated using a systematic, evidence-based approach. Thus, this systematic review is aimed at critically evaluating the data from randomized clinical trials examining the clinical efficacy of Healing Touch as a supportive care modality for any medical condition.

    Objective To review the literature on the clinical progress in cauda equina syndrome (CES), including the epidemic history, pathogenesis, diagnosis, treatment policy and prognosis.Data sources All reports on CES in the literature were searched in PubMed, Ovid, Springer, Elsevier, and the Chinese Biomedical Literature Disk using the key terms "cauda equina syndrome", "diagnosis", "treatment', "prognosis" and "evidence-based medicine".Study selection Original milestone articles and critical reviews wdtten by major pioneer investigators about the cauda equina syndrome were selected.Results CES is rare, both atraumatically and traumatically. Males and females are equally affected. The incidence of CES is variable, depending on the etiology of the syndrome. The most common cause of CES is herniation of a lumbar intervertebral disc. CES symptoms may have sudden onset and evolve rapidly or sometimes chronic ally. Each type of CES has different typical signs and symptoms. Low back pain may be the most significant symptoms, accompanied by sciatica, lower extremities weakness, saddle or perianal hypoesthesia, sexual impotence, and sphincter dysfunction. MRI is usually the preferred investigation approach. Patients who have had CES are difficult to return to a normal status.Conclusions The diagnosis of CES is primarily based on a careful history inquiry and clinical examination, assisted by elective radiologic investigations. Early diagnosis and early surgical decompression are crucial for a favorable outcome in most CES cases.

    Full Text Available In combination with whole report and partial report tasks, the Theory of Visual Attention (TVA can be used to estimate individual differences in five basic attentional parameters: The visual processing speed, the storage capacity of visual short-term memory, the perceptual threshold, the efficiency of top-down selectivity, and the spatial bias of attentional weighting. TVA-based assessment has been used in about 30 studies to investigate attentional deficits in a range of neurological and psychiatric conditions: (a neglect and simultanagnosia, (b reading disturbances, (c aging and neurodegenerative diseases, and most recently (d neurodevelopmental disorders. The article introduces TVA based assessment, discusses its methodology and psychometric properties, and reviews the progress made in each of the four research fields. The empirical results demonstrate the general usefulness of TVA-based assessment for many types of clinical neuropsychological research. The method’s most important qualities are cognitive specificity and theoretical grounding, but it is also characterized by good reliability and sensitivity to minor deficits. The review concludes by pointing to promising new areas for clinical TVA-based research.

  16. The Clinical Features of Myositis-Associated Autoantibodies: a Review.

    The idiopathic inflammatory myopathies (IIM) are a group of autoimmune diseases traditionally defined by clinical manifestations including skeletal muscle weakness, skin rashes, elevated skeletal muscle enzymes, and neurophysiological and/or histological evidence of muscle inflammation. Patients with myositis overlap can develop other features including parenchymal lung disease, inflammatory arthritis, gastrointestinal manifestations and marked constitutional symptoms. Although patients may be diagnosed as having polymyositis (PM) or dermatomyositis (DM) under the IIM spectrum, it is quite clear that disease course between subgroups of patients is different. For example, interstitial lung disease may predominate in some, whereas cutaneous complications, cancer risk, or severe refractory myopathy may be a significant feature in others. Therefore, tools that facilitate diagnosis and indicate which patients require more detailed investigation for disease complications are invaluable in clinical practice. The expanding field of autoantibodies (autoAbs) associated with connective tissue disease (CTD)-myositis overlap has generated considerable interest over the last few years. Using an immunological diagnostic approach, this group of heterogeneous conditions can be separated into a number of distinct clinical phenotypes. Rather than diagnose a patient as simply having PM, DM or overlap CTD, we can define syndromes to differentiate disease subsets that emphasise clinical outcomes and guide management. There are now over 15 CTD-myositis overlap autoAbs found in patients with a range of clinical manifestations including interstitial pneumonia, cutaneous disease, cancer-associated myositis and autoimmune-mediated necrotising myopathy. This review describes their diagnostic utility, potential role in disease monitoring and response to treatment. In the future, routine use of these autoAb will allow a stratified approach to managing this complex set of conditions.

    Introduction Prophylactic appendicectomy is performed prior to military, polar and space expeditions to prevent acute appendicitis in the field. However, the risk-benefit ratio of prophylactic surgery is controversial. This study aimed to systematically review the evidence for prophylactic appendicectomy. It is supplemented by a clinical example of prophylactic surgery resulting in life-threatening complications. Methods A systematic review was performed using MEDLINE(®) and the Cochrane Central Register of Controlled Trials. Keyword variants of 'prophylaxis' and 'appendicectomy' were combined to identify potential papers for inclusion. Papers related to prophylactic appendicectomy risks and benefits were reviewed. Results Overall, 511 papers were identified, with 37 papers satisfying the inclusion criteria. Nine reported outcomes after incidental appendicectomy during concurrent surgical procedures. No papers focused explicitly on prophylactic appendicectomy in asymptomatic patients. The clinical example outlined acute obstruction secondary to adhesions from a prophylactic appendicectomy. Complications after elective appendicectomy versus the natural history of acute appendicitis in scenarios such as polar expeditions or covert operations suggest prophylactic appendicectomy may be appropriate prior to extreme situations. Nevertheless, the long-term risk of adhesion related complications render prophylactic appendicectomy feasible only when the short-term risk of acute appendicitis outweighs the long-term risks of surgery. Conclusions Prophylactic appendicectomy is rarely performed and not without risk. This is the first documented evidence of long-term complications following prophylactic appendicectomy. Surgery should be considered on an individual basis by balancing the risks of acute appendicitis in the field with the potential consequences of an otherwise unnecessary surgical procedure in a healthy patient.

    Full Text Available Abstract Background The use of telemedicine is growing, but its efficacy for achieving comparable or improved clinical outcomes has not been established in many medical specialties. The objective of this systematic review was to evaluate the efficacy of telemedicine interventions for health outcomes in two classes of application: home-based and office/hospital-based. Methods Data sources for the study included deports of studies from the MEDLINE, EMBASE, CINAHL, and HealthSTAR databases; searching of bibliographies of review and other articles; and consultation of printed resources as well as investigators in the field. We included studies that were relevant to at least one of the two classes of telemedicine and addressed the assessment of efficacy for clinical outcomes with data of reported results. We excluded studies where the service did not historically require face-to-face encounters (e.g., radiology or pathology diagnosis. All included articles were abstracted and graded for quality and direction of the evidence. Results A total of 25 articles met inclusion criteria and were assessed. The strongest evidence for the efficacy of telemedicine in clinical outcomes comes from home-based telemedicine in the areas of chronic disease management, hypertension, and AIDS. The value of home glucose monitoring in diabetes mellitus is conflicting. There is also reasonable evidence that telemedicine is comparable to face-to-face care in emergency medicine and is beneficial in surgical and neonatal intensive care units as well as patient transfer in neurosurgery. Conclusions Despite the widespread use of telemedicine in virtually all major areas of health care, evidence concerning the benefits of its use exists in only a small number of them. Further randomized controlled trials must be done to determine where its use is most effective.

  19. Autogenic training: a narrative and quantitative review of clinical outcome.

    1994-09-01

    This review of controlled outcome research on Autogenic Training complements the literature by pooling narrative and quantitative approaches, by including only studies with experimental controls, by integrating the English and German literature, and by adding research findings published since the last review. Whereas previous reviews have already reported positive effects of Autogenic Training for migraine, insomnia, and test anxiety, additional supportive findings for angina pectoris, asthma, childbirth, eczema, hypertension, infertility, Raynaud's disease, and recovery from myocardial infarction are discussed here. The impact of protocol variations on outcome is described, and the specificity of Autogenic Training relative to other stress management techniques is highlighted. Quantitative findings suggested that Autogenic Training was associated with medium-sized pre- to posttreatment effects ranging from d = .43 for biological indices of change to d = .58 for psychological and behavioral indices thus matching effect sizes for other biobehavioral treatment techniques like biofeedback and muscular relaxation. Length of treatment did not affect clinical outcome. The discussion emphasizes how narrative and quantitative strategies complement one another.

    Autoimmune hepatitis (AIH) fulfills the generally accepted contemporary criteria of an autoimmune liver disease: the presence of autoantibodies and autoreactive T cells, a female gender bias, association with other autoimmune diseases, response to immunosuppressive therapy and strong associations with the major histocompatibility complex HLA loci. It occurs worldwide in both children and adults and is marked by both etiopathogenic and clinical heterogeneity, differing from the other putative autoimmune liver diseases, primary biliary cirrhosis (PBC) and primary sclerosing cholangitis (PSC), albeit occasionally presenting with overlapping features of PBC or PSC. Although diagnostic criteria have been established and validated, there are still major issues to be clarified due to its variability, such as autoantibody-negative AIH, drug-induced AIH, AIH sharing features with PBC or PSC, and post-transplant de novo AIH. In view of the diverse presentations and courses, including classical chronic onset, acute and acute severe onset, cirrhosis and decompensated cirrhosis, individualized management of patients is indicated. Each patient should receive a personalized analysis of the benefits and side effect risks of drugs. Herein we describe a comprehensive review of the clinical phenotypes of AIH underscoring its clinical heterogeneity.

    Full Text Available Diabetes mellitus is a public health problem which leads to serious complications over time. Experimentally, many herbs have been recommended for treating diabetes. In most cases, however, the recommendations are based on animal studies and limited pieces of evidence exist about their clinical usefulness. This review focused on the herbs, the hypoglycemic actions of which have been supported by three or more clinical studies. The search was done in Google Scholar, Medline and Science Direct databases using the key terms diabetes, plants, herbs, glucose and patients. According to the clinical studies, Aegle marmelos, Allium cepa, Gymnema sylvestre, Momordica charantia, Ocimum sanctum, Nigella sativa, Ocimum sanctum, Panax quinquefolius, Salacia reticulate, Silybum marianum and Trigonella foenum-graecum have shown hypoglycemic and, in some cases, hypolipidemic activities in diabetic patients. Among them, Gymnema sylvestre, Momordica charantia, Silybum marianum and Trigonella foenum-graecum have acquired enough reputation for managing diabetes. Thus, it seems that physicians can rely on these herbs and advise for the patients to improve management of diabetes.

    Cytochrome P450 17A1 (CYP17A1; also P450c17and P450sccII) is a critically important enzyme in humans that catalyzes the formation of all endogenous androgens. It is an atypical cytochrome P450 enzyme in that it catalyzes two distinct types of substrate oxidation. Through its hydroxylase activity, it catalyzes the 17α-hydroxylation of pregnenolone to 17α-OH pregnenolone. Subsequently, through its C17,20lyase activity, it can further convert 17α-OH pregnenolone to the androgen dehydroepiandrosterone, which is a precursor to androstenedione, testosterone, and dihydrotestosterone. The importance of androgens in diseases such as prostate cancer has been appreciated for decades and the discovery of extra-testicular formation of androgens has helped clarify the pathology of the disease, especially the castrate- resistant disease. Therefore, specific inhibition of CYP17A1 by therapeutic intervention has been an area of considerable effort in several research laboratories. This basic research has led to the discovery of several promising drug candidates followed by the conduct of several clinical trials. Recently, all these efforts have culminated in the first approval by FDA of an inhibitor of CYP17A1 for the treatment of castrate-resistant prostate cancer. Ongoing clinical trials are now evaluating the agent in earlier stages of prostate cancer and even rare forms of androgen-dependent breast cancer. Accordingly, this review focuses on the biochemistry, chemistry, and clinical inhibitors of CYP17A1.

    Gaucher disease (GD), one of the most prevalent lysosomal storage diseases, is associated with glucocerebroside accumulation in cells of the monocyte-macrophage system in various organs, including the liver. Evaluating and managing liver disease in patients with Gaucher disease may be challenging. While hepatic involvement is common in Gaucher disease, its severity, and clinical significance span a wide spectrum, ranging from sub-clinical involvement to liver cirrhosis with its associated complications including portal hypertension. Apart from liver involvement in Gaucher disease, patients with may also suffer from other comorbidities involving the liver. That Gaucher disease itself can mimic hepatic lesions, affect laboratory tests used to characterize liver disease, and may be associated with non-cirrhotic portal hypertension, complicates the diagnostic approach even more. Better understanding of liver involvement in Gaucher disease can spare patients unnecessary invasive testing, and assist physicians in decision making when evaluating patients with Gaucher disease suspected for significant liver disease. This review describes the various clinical manifestations, laboratory and imaging abnormalities that may be encountered when following patients with Gaucher disease for liver involvement. The mechanism for liver disease are discussed, as well as the possible hepato-protective effect of glucocerebroside, and the a diagnostic and treatment approaches.

    Bovine colostrum, the first milk that cows produce after parturition, contains high levels of growth factors and immunomodulatory components. Some healthy and diseased individuals may gain health benefits by consuming bovine colostrum as a food supplement. This review provides a systematic, critical evaluation of the current state of knowledge in this area. Fifty-one eligible studies were identified from the following databases: Medline, Embase, Global Health, the Cochrane Library, and the Cumulative Index to Nursing and Allied Health Literature. Studies were heterogeneous with regard to populations, outcomes, and methodological quality, as judged by the Jadad assessment tool. Many studies used surrogate markers to study the effects of bovine colostrum. Studies suggesting clinical benefits of colostrum supplementation were generally of poor methodological quality, and results could not be confirmed by other investigators. Bovine colostrum may provide gastrointestinal and immunological benefits, but further studies are required before recommendations can be made for clinical application. Animal models may help researchers to better understand the mechanisms of bovine colostrum supplementation, the dosage regimens required to obtain clinical benefits, and the optimal methods for testing these effects in humans.

    Aloe vera L., is a plant used worldwide as folk remedy for the treatment of various ailments, including skin disorders. Its gel is present in cosmetics, medicinal products and food supplements. Psoriasis, an immune-mediated chronic inflammatory disease, involving mainly the skin, affects about the 2-3% of general population. Conventional pharmacological treatments for psoriasis can have limited effectiveness and can cause adverse reactions. For this reason often psoriatic patients look for alternative treatments based on natural products containing Aloe vera. We conducted a systematic review of clinical trials assessing effectiveness and safety of aloe for the treatment of psoriasis. Clinical studies published in English were considered; a total of four clinical trials met inclusion criteria. Studies were also evaluated by using the Jadad scale and Consort Statement in Reporting Clinical trials of Herbal Medicine Intervention. Quality and methodological accuracy of considered studies varied considerably, and some crucial information to reproduce clinical results was missing. We conclude that administration of aloe as cutaneous treatment is generally well tolerated, as no serious side effects were reported. Results on the effectiveness of Aloe vera are contradictory; our analysis reveals the presence of methodological gaps preventing to reach final conclusions.

    Full Text Available 24 cases of fulminant hepatitis (FH hospitalized in the Clínica de Doenças Infecciosas e Parasitárias do Hospital das Clínicas da Faculdade de Medicina da Universidade de São Paulo during the period from January 1976 to December 1986 were reviewed from their clinical, epidemiological and laboratorial aspects. 88% of the patients died; 20 patients (83% presented hemorrhages and, of these, 19 died. Bacterial infections occurred in 14 patients (58% all of whom died. Ascitis was noted in 3 cases; cerebral edema was present in 16 cases. Maximal ALT levels for each patient during hospitalization ranged widely from 81 to 4,460 UI/l. Thirteen patients presented high creatinine levels (54%. Prothrombin time activity ranged from 2.1% to 67%. Fever was present in 20 cases (83%. Encephalopathy occurred within the first 2 weeks of illness in 72% of the cases. In 7 cases other illnesses were present. The etiology could not be determined in 13 cases. In 3 cases it was due to yellow fever and 6 cases were caused by viruses other than yellow fever. In one case the cause was drug usage and in another case, possibly alcohol. The authors believe that the clinical definition of FH requires further discussion before it is established. In this study FH is a young person's disease. The mortality found was similar to that by other authors. Factors that contributed to death were: hemorrhages and bacterial infection. Factors that worsened the prognosis of hepatitis were: associated illnesses and surgical procedure. The levels of ALT during hospitalization did not correlate well with the severity of the hepatitis. The authors believe that yellow fever should be considered a cause of FH where the clinical picture meets the criteria for such, although its mechanisms of encephalopathy remain obscure. The clinical details of the 3 cases of yellow fever are presented.

Phenelzine (Nardil® prescribing information notes: “The potentiation of sympathomimetic substances and related compounds by MAO inhibitors may result in hypertensive crises (see WARNINGS. Therefore, patients being treated with NARDIL should not take […] L-tyrosine […]”. Interest in the scientific foundation of this claim was generated during routine patient care. A comprehensive literature search of Google Scholar and PubMed revealed no reported cases of hypertensive crisis associated with concomitant administration of L-tyrosine and phenelzine. Review of current US Food and Drug Administration nutritional guidelines relating to ongoing phenelzine studies reveals no mention and requires no consideration of L-tyrosine ingestion in combination with phenelzine. This paper is intended to provide an objective review of the science to then allow the reader to formulate the final opinion.

    2014-04-01

    Radiation therapy has long played a role in the management of melanoma. Recent advances have also demonstrated the efficacy of immunotherapy in the treatment of melanoma. Preclinical data suggest a biologic interaction between radiation therapy and immunotherapy. Several clinical studies corroborate these findings. This review will summarize the outcomes of studies reporting on patients with melanoma treated with a combination of radiation therapy and immunotherapy. Vaccine therapies often use irradiated melanoma cells, and may be enhanced by radiation therapy. The cytokines interferon-α and interleukin-2 have been combined with radiation therapy in several small studies, with some evidence suggesting increased toxicity and/or efficacy. Ipilimumab, a monoclonal antibody which blocks cytotoxic T-lymphocyte antigen-4, has been combined with radiation therapy in several notable case studies and series. Finally, pilot studies of adoptive cell transfer have suggested that radiation therapy may improve the efficacy of treatment. The review will demonstrate that the combination of radiation therapy and immunotherapy has been reported in several notable case studies, series and clinical trials. These clinical results suggest interaction and the need for further study.

    Full Text Available Background: The phylum Cnidarians have over nine thousand species that approximately, one hundred species are dangerous for humans. Annually, a large number of deaths were reported due to jellyfish stings. The manifestations depend on their species and kind of venoms, and include the local and systemic manifestations. A number of methods and compounds were used and under investigation for management of injuries with jellyfishes. Due to the lack of an integrated systematic review, the current study was done. Materials and Methods: The PubMed data bank was searched for the term “Jellyfish”. A total of 1677 papers were found. These papers were divided into three categories: medical, biomedical and biotechnological fields. The medical category was further divided into three subcategories comprising systemic manifestations, cutaneous manifestations and treatments for the stings of jellyfishes. The biomedical category was further subdivided into genomics, proteomics, and biology of venoms, mechanisms of actions and products of biomedical significance. In this part of systematic review, the medical aspects of injuries with jellyfishes were evaluated. Results: The clinical manifestations in jellyfish envenomation depend on their species and the nature of venoms. The most common clinical manifestations of jellyfish stings are cutaneous presentations like urticasia, erythema, swelling, vesicles and severe dermonectoric manifestations. Systemic manifestations were seen in the stings of box jellyfishes, Portuguese man-of-war and in Irukandji syndrome. The most common recommendations for jellyfish envenomation managements include decreasing the local effects of venom, prevention of the venomous nematocysts release, and Controlling of systemic reactions. Application of commercial vinegar (4 - 6% acetic acid, hot water immersion (HWI (42 ° C for 20 minutes, ice packs, sea water rinsing for inactivating nematocysts, administration of topical and parenteral

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

    2014-01-01

    Full Text Available The major goal of traditional platelet function tests has been to screen and diagnose patients who present with bleeding problems. However, as the central role of platelets implicated in the etiology of arterial thrombotic diseases such as myocardial infarction and stroke became widely known, platelet function tests are now being promoted to monitor the efficacy of antiplatelet drugs and also to potentially identify patients at increased risk of thrombosis. Beyond hemostasis and thrombosis, an increasing number of studies indicate that platelets play an integral role in intercellular communication, are mediators of inflammation, and have immunomodulatory activity. As new potential biomarkers and technologies arrive at the horizon, platelet functions testing appears to take on a new aspect. This review article discusses currently available clinical application of platelet function tests, placing emphasis on essential characteristics.

    Final-year veterinary students must meet baseline clinical competency upon completion of their training for entry to practice. Workplace-based assessments (WBAs), widely used in human medical training to assess post-graduate students' professionalism and clinical performance, have recently been adopted in undergraduate veterinary clinical teaching environments. WBAs should support veterinary trainees' learning in a clinical teaching environment, though utility of WBAs within veterinary education may differ from that in medical training due to differences in context and in learners' stage of clinical development. We conducted focus groups with final-year veterinary students and clinical instructors following the implementation of three WBAs (Direct Observation of Procedural Skills [DOPS], the Mini-Clinical evaluation exercise [Mini-CEX], and the In-Training Evaluation Report [ITER]) during a small-animal primary-veterinary-care rotation. Students and clinical instructors viewed the DOPS and Mini-CEX as feasible and valuable learning and assessment tools that offered an overall opportunity for timely in-the-moment feedback. Instructors viewed the ITER as less feasible in the context of a service-oriented veterinary clinical teaching environment. Students believed the ITER had potential to be informative, although in its existing application the ITER had limited utility due to time constraints on instructors that prevented them from providing students with individualized and specific feedback. In service-oriented veterinary clinical teaching environments, successful implementation of WBAs requires balancing provision of feedback to students, time demands on clinical instructors, and flexibility of assessment tools.

    Full Text Available Abstract Background The HELLP syndrome is a serious complication in pregnancy characterized by haemolysis, elevated liver enzymes and low platelet count occurring in 0.5 to 0.9% of all pregnancies and in 10–20% of cases with severe preeclampsia. The present review highlights occurrence, diagnosis, complications, surveillance, corticosteroid treatment, mode of delivery and risk of recurrence. Methods Clinical reports and reviews published between 2000 and 2008 were screened using Pub Med and Cochrane databases. Results and conclusion About 70% of the cases develop before delivery, the majority between the 27th and 37th gestational weeks; the remainder within 48 hours after delivery. The HELLP syndrome may be complete or incomplete. In the Tennessee Classification System diagnostic criteria for HELLP are haemolysis with increased LDH (> 600 U/L, AST (≥ 70 U/L, and platelets 9/L. The Mississippi Triple-class HELLP System further classifies the disorder by the nadir platelet counts. The syndrome is a progressive condition and serious complications are frequent. Conservative treatment (≥ 48 hours is controversial but may be considered in selected cases

    Neuroleptic malignant syndrome (NMS) is a rare but potentially life-threatening side-effect that can occur in response to treatment with antipsychotic drugs. Symptoms commonly include hyperpyrexia, muscle rigidity, autonomic dysfunction and altered mental status. In the current review we provide an overview on past and current developments in understanding the causes and treatment of NMS. Studies on the epidemiological incidence of NMS are evaluated, and we provide new data from the Canada Vigilance Adverse Reaction Online database to elaborate on drug-specific and antipsychotic drug polypharmacy instances of NMS reported between 1965 and 2012. Established risk factors are summarized with an emphasis on pharmacological and environmental causes. Leading theories about the etiopathology of NMS are discussed, including the potential contribution of the impact of dopamine receptor blockade and musculoskeletal fiber toxicity. A clinical perspective is provided whereby the clinical presentation and phenomenology of NMS is detailed, while the diagnosis of NMS and its differential is expounded. Current therapeutic strategies are outlined and the role for both pharmacological and non-pharmacological treatment strategies in alleviating the symptoms of NMS are discussed.

    The management of clinical solid waste (CSW) continues to be a major challenge, particularly, in most healthcare facilities of the developing world. Poor conduct and inappropriate disposal methods exercised during handling and disposal of CSW is increasing significant health hazards and environmental pollution due to the infectious nature of the waste. This article summarises a literature review into existing CSW management practices in the healthcare centers. The information gathered in this paper has been derived from the desk study of open literature survey. Numerous researches have been conducted on the management of CSW. Although, significant steps have been taken on matters related to safe handling and disposal of the clinical waste, but improper management practice is evident from the point of initial collection to the final disposal. In most cases, the main reasons of the mismanagement of CSW are the lack of appropriate legislation, lack of specialized clinical staffs, lack of awareness and effective control. Furthermore, most of the healthcare centers of the developing world have faced financial difficulties and therefore looking for cost effective disposal methods of clinical waste. This paper emphasizes to continue the recycle-reuse program of CSW materials after sterilization by using supercritical fluid carbon dioxide (SF-CO2) sterilization technology at the point of initial collection. Emphasis is on the priority to inactivate the infectious micro-organisms in CSW. In that case, waste would not pose any threat to healthcare workers. The recycling-reuse program would be carried out successfully with the non-specialized clinical staffs. Therefore, the adoption of SF-CO2 sterilization technology in management of clinical solid waste can reduce exposure to infectious waste, decrease labor, lower costs, and yield better compliance with regulatory. Thus healthcare facilities can both save money and provide a safe environment for patients, healthcare staffs

  1. Accelerometer measurement of upper extremity movement after stroke: a systematic review of clinical studies.

    2014-10-09

    The aim of this review was to identify and summarise publications, which have reported clinical applications of upper limb accelerometry for stroke within free-living environments and make recommendations for future studies. Data was searched from MEDLINE, Scopus, IEEExplore and Compendex databases. The final search was 31st October 2013. Any study was included which reported clinical assessments in parallel with accelerometry in a free-living hospital or home setting. Study quality is reflected by participant numbers, methodological approach, technical details of the equipment used, blinding of clinical measures, whether safety and compliance data was collected. First author screened articles for inclusion and inclusion of full text articles and data extraction was confirmed by the third author. Out of 1375 initial abstracts, 8 articles were included. All participants were stroke patients. Accelerometers were worn for either 24 hours or 3 days. Data were collected as summed acceleration counts over a specified time or as the duration of active/inactive periods. Activity in both arms was reported by all studies and the ratio of impaired to unimpaired arm activity was calculated in six studies. The correlation between clinical assessments and accelerometry was tested in five studies and significant correlations were found. The efficacy of a rehabilitation intervention was assessed using accelerometry by three studies: in two studies both accelerometry and clinical test scores detected a post-treatment difference but in one study accelerometry data did not change despite clinical test scores showing motor and functional improvements. Further research is needed to understand the additional value of accelerometry as a measure of upper limb use and function in a clinical context. A simple and easily interpretable accelerometry approach is required.

    Mucopolysaccharidosis type IVA (MPS IVA) was described in 1929 by Luis Morquio from Uruguay and James Brailsford from England, and was later found as an autosomal recessive lysosomal storage disease. MPS IVA is caused by mutations in the gene encoding the enzyme, N-acetylgalactosamine-6-sulfate sulfatase (GALNS). Reduced GALNS activity results in impaired catabolism of two glycosaminoglycans (GAGs), chondroitin-6-sulfate (C6S) and keratan sulfate (KS). Clinical presentations of MPS IVA reflect a spectrum of progression from a severe "classical" phenotype to a mild "attenuated" phenotype. More than 180 different mutations have been identified in the GALNS gene, which likely explains the phenotypic heterogeneity of the disorder. Accumulation of C6S and KS manifests predominantly as short stature and skeletal dysplasia (dysostosis multiplex), including atlantoaxial instability and cervical cord compression. However, abnormalities in the visual, auditory, cardiovascular, and respiratory systems can also affect individuals with MPS IVA. Diagnosis is typically based on clinical examination, skeletal radiographs, urinary GAG, and enzymatic activity of GALNS in blood cells or fibroblasts. Deficiency of GALNS activity is a common assessment for the laboratory diagnosis of MPS IVA; however, with recently increased availability, gene sequencing for MPS IVA is often used to confirm enzyme results. As multiple clinical presentations are observed, diagnosis of MPS IVA may require multi-system considerations. This review provides a history of defining MPS IVA and how the understanding of the disease manifestations has changed over time. A summary of the accumulated knowledge is presented, including information from the International Morquio Registry. The classical phenotype is contrasted with attenuated cases, which are now being recognized and diagnosed more frequently. Laboratory based diagnoses of MPS IVA are also discussed.

    Food allergy is defined as an adverse immune response towards food proteins or as a form of a food intolerance associated with a hypersensitive immune response. It should also be reproducible by a double-blind placebo-controlled food challenge. Many reported that food reactions are not allergic but are intolerances. Food allergy often presents to clinicians as a symptom complex. This review focuses on the clinical spectrum and manifestations of various forms of food allergies. According to clinical presentations and allergy testing, there are three types of food allergy: IgE mediated, mixed (IgE/Non-IgE), and non-IgE mediated (cellular, delayed type hypersensitivity). Recent advances in food allergy in early childhood have highlighted increasing recognition of a spectrum of delayed-onset non-IgE-mediated manifestation of food allergy. Common presentations of food allergy in infancy including atopic eczema, infantile colic, and gastroesophageal reflux. These clinical observations are frequently associated with food hypersensitivity and respond to dietary elimination. Non-IgE-mediated food allergy includes a wide range of diseases, from atopic dermatitis to food protein-induced enterocolitis and from eosinophilic esophagitis to celiac disease. The most common food allergies in children include milk, egg, soy, wheat, peanut, treenut, fish, and shellfish. Milk and egg allergies are usually outgrown, but peanut and treenut allergy tends to persist. The prevalence of food allergy in infancy is increasing and may affect up to 15-20 % of infants. The alarming rate of increase calls for a public health approach in the prevention and treatment of food allergy in children.

    2016-01-01

    Arterial spin labeling (ASL) is a completely noninvasive magnetic resonance imaging (MRI) perfusion method for quantitatively measuring cerebral blood flow utilizing magnetically labeled arterial water. Advances in the technique have enabled the major MRI vendors to make the sequence available to the clinical neuroimaging community. Consequently, ASL is being increasingly incorporated into the routine neuroimaging protocol. Although a variety of ASL techniques are available, the ISMRM Perfusion Study Group and the European ASL in Dementia Consortium have released consensus guidelines recommending standardized implementation of 3D pseudocontinuous ASL with background suppression. The purpose of this review, aimed at the large number of neuroimaging clinicians who have either no or limited experience with this 3D pseudocontinuous ASL, is to discuss the common and clinically significant artifacts that may be encountered with this technique. While some of these artifacts hinder accurate interpretation of studies, either by degrading the images or mimicking pathology, there are other artifacts that are of clinical utility, because they increase the conspicuity of pathology. Cognizance of these artifacts will help the physician interpreting ASL to avoid potential diagnostic pitfalls, and increase their level of comfort with the technique.

    Full Text Available Children and patients with cognitive deficits may find it difficult to understand the implication of research. In the European Union (EU, clinical studies outside the EU directives concerning medicinal products or medical devices, i.e., "miscellaneous clinical studies", have no legally mandated timelines for institutional review boards' (IRB decisions.To evaluate the review process of IRBs for two different "miscellaneous" multicenter clinical research protocols involving vulnerable subjects (children and adult stroke patients.Descriptive and comparative statistics. Protocol 1 is a prospective, multicenter, cross-sectional screening study of a symptomatic pediatric population at risk for Fabry disease involving genetic testing (NCT02152189. Protocol 2 is a prospective, multicenter, randomized, controlled, open-label, blinded endpoint post-market study to evaluate the effectiveness of stent retrievers (NCT02135926. After having obtained positive initial IRB votes at the main study site, both protocols were subsequently submitted to the remaining IRBs.Protocol 1 was submitted to 19 IRBs. No IRB objected to the study. Median time-to-final vote was 34 (IQR 10-65; range 0 to 130 days. Two IRBs accepted the coordinating center's IRB votes without re-evaluation. Changes to the informed consent documents were asked by 7/19 IRBs, amendments to the protocol by 2. Protocol 2 was submitted to 16 IRBs. Fifteen decisions were made. No IRB objected to the study. Median time-to final vote was 59 (IQR 10 to 65; range 0 to 128 days, which was not statistically significantly different compared with protocol 1 (Wilcoxon test. Two IRBs accepted a previous IRB decision and did not conduct an independent review. Eight/16 IRBs required changes to the informed consent documents; two IRBs recommended an amendment of the protocol.Both clinical research protocols involving vulnerable populations were well accepted.

    Iodothyronine deiodinases represent a family of selenoproteins involved in peripheral and local homeostasis of thyroid hormone action. Deiodinases are expressed in multiple organs and thyroid hormone affects numerous biological systems, thus genetic variation in deiodinases may affect multiple clinical endpoints. Interest in clinical effects of genetic variation in deiodinases has clearly increased. We aimed to provide an overview for the role of deiodinase polymorphisms in human physiology and morbidity. In this systematic review, studies evaluating the relationship between deiodinase polymorphisms and clinical parameters in humans were eligible. No restrictions on publication date were imposed. The following databases were searched up to August 2013: Pubmed, EMBASE (OVID-version), Web of Science, COCHRANE Library, CINAHL (EbscoHOST-version), Academic Search Premier (EbscoHOST-version), and ScienceDirect. Deiodinase physiology at molecular and tissue level is described, and finally the role of these polymorphisms in pathophysiological conditions is reviewed. Deiodinase type 1 (D1) polymorphisms particularly show moderate-to-strong relationships with thyroid hormone parameters, IGF1 production, and risk for depression. D2 variants correlate with thyroid hormone levels, insulin resistance, bipolar mood disorder, psychological well-being, mental retardation, hypertension, and risk for osteoarthritis. D3 polymorphisms showed no relationship with inter-individual variation in serum thyroid hormone parameters. One D3 polymorphism was associated with risk for osteoarthritis. Genetic deiodinase profiles only explain a small proportion of inter-individual variations in serum thyroid hormone levels. Evidence suggests a role of genetic deiodinase variants in certain pathophysiological conditions. The value for determination of deiodinase polymorphism in clinical practice needs further investigation.

    2016-01-01

    Full Text Available Introduction: Craving is recognized as a formidable barrier in the management of patients with alcohol dependence. Among pharmacological agents that have been used in experimental studies for reduction in craving, baclofen appears to have a significant advantage over other agents. Methodology: The study is retrospective chart review of patients (n = 113 who have been treated with baclofen for alcohol dependence in a tertiary hospital of North India. Baseline assessments included sociodemography, motivation, quantity-frequency of alcohol use, and other alcohol-related clinical parameters. Weekly assessments, for a period of 4 weeks, were extracted from records which included dose of baclofen, craving intensity, and alcohol consumption. Results: The study sample was predominantly male, mean age of 41.49 (±9.75 years, most having a family history of substance use (70.97%, and many reporting binge use pattern in last year (49.46%. Baseline assessment revealed 48.7% of the sample was in precontemplation phase for alcohol use and 70% reported severe and persistent craving. This persistent craving was reported by only 15% of the sample by the end of 4 weeks treatment with baclofen (20–40 mg/day. Thirty-four percent of patients reported continued problematic use of alcohol by the end of 4 weeks. Conclusion: Our clinical experience suggests that baclofen reduces craving and alcohol consumption including in those with poor motivation. The drug causes few side effects and does not add to the intoxication effect of alcohol. Considering that baclofen is safe in those with liver cirrhosis and reduces withdrawal symptoms due to alcohol, a controlled trial comparing it with standard treatment is required.

    Since its introduction in 1996, the Genesis II Total Knee System has produced good clinical results in patients undergoing primary total knee replacement. A systematic review of the literature-the first of its kind for this device-was undertaken to collect data on the Genesis II in order to provide a better understanding of its medium- to long-term performance. Of 124 Genesis II-related studies published in the literature, 11 met the eligibility criteria and were included in the final analysis. The included studies had a mean follow-up length of 38.1 months. Data from 1201 knees were available for review. Patients were an average of 70.5 years of age and predominantly female (63%). Findings indicated that the revision rate with this implant is low with up to 11.9 years of follow-up, with 14 revisions in total. The survival rate ranged from 100% at 1 and 2 years to 96.0% at 11.9 years. The mean Knee Society knee score improved 51.0 points from preoperative to postoperative evaluation. In conclusion, the Genesis II exhibited good clinical performance with up to 11 years follow-up, with an encouraging rate of survival and improvement in function. Additional studies with larger sample sizes and longer follow-up periods are needed to better understand the long-term performance of this implant.

    Considerable emphasis is currently placed on reducing healthcare-associated infection through improving hand hygiene compliance among healthcare professionals. There is also increasing discussion in the lay media of perceived poor hand hygiene compliance among healthcare staff. Our aim was to report the outcomes of a systematic search for peer-reviewed, published studies - especially clinical trials - that focused on hand hygiene compliance among healthcare professionals. Literature published between December 2009, after publication of the World Health Organization (WHO) hand hygiene guidelines, and February 2014, which was indexed in PubMed and CINAHL on the topic of hand hygiene compliance, was searched. Following examination of relevance and methodology of the 57 publications initially retrieved, 16 clinical trials were finally included in the review. The majority of studies were conducted in the USA and Europe. The intensive care unit emerged as the predominant focus of studies followed by facilities for care of the elderly. The category of healthcare worker most often the focus of the research was the nurse, followed by the healthcare assistant and the doctor. The unit of analysis reported for hand hygiene compliance was 'hand hygiene opportunity'; four studies adopted the 'my five moments for hand hygiene' framework, as set out in the WHO guidelines, whereas other papers focused on unique multimodal strategies of varying design. We concluded that adopting a multimodal approach to hand hygiene improvement intervention strategies, whether guided by the WHO framework or by another tested multimodal framework, results in moderate improvements in hand hygiene compliance.

    Clinical experiments are always used to evaluate the safety and validity of medical devices. The experiments have two types of clinical trying and testing. Ethic review must be done by the ethics committee of the medical department with the qualification of clinical research, and the approval must be made before the experiments. In order to ensure the safety and validity of clinical experiments of medical devices in medical institutions, the contents, process and approval criterions of the ethic review were analyzed and discussed.

  20. Review of clinical and laboratory features of human Brucellosis

    Mantur B

    2007-01-01

    Full Text Available Infection with Brucella spp. continues to pose a human health risk globally despite strides in eradicating the disease from domestic animals. Brucellosis has been an emerging disease since the discovery of Brucella melitensis by Sir David Bruce in 1887. Although many countries have eradicated B. abortus from cattle, in some areas B. melitensis and B. suis have emerged as causes of this infection in cattle, leading to human infections. Currently B. melitensis remains the principal cause of human brucellosis worldwide including India. The recent isolation of distinct strains of Brucella from marine mammals as well as humans is an indicator of an emerging zoonotic disease. Brucellosis in endemic and non-endemic regions remains a diagnostic puzzle due to misleading non-specific manifestations and increasing unusual presentations. Fewer than 10% of human cases of brucellosis may be clinically recognized and treated or reported. Routine serological surveillance is not practiced even in Brucella - endemic countries and we suggest that this should be a part of laboratory testing coupled with a high index of clinical suspicion to improve the level of case detection. The screening of family members of index cases of acute brucellosis in an endemic area should be undertaken to pick up additional unrecognised cases. Rapid and reliable, sensitive and specific, easy to perform and automated detection systems for Brucella spp. are urgently needed to allow early diagnosis and adequate antibiotic therapy in time to decrease morbidity / mortality. The history of travel to endemic countries along with exposure to animals and exotic foods are usually critical to making the clinical diagnosis. Laboratory testing is indispensable for diagnosis. Therefore alertness of clinician and close collaboration with microbiologist are essential even in endemic areas to correctly diagnose and treat this protean human infection. Existing treatment options, largely based on

  1. A Review of Glass-Ionomer Cements for Clinical Dentistry.

    Sidhu, Sharanbir K; Nicholson, John W

    2016-06-28

    This article is an updated review of the published literature on glass-ionomer cements and covers their structure, properties and clinical uses within dentistry, with an emphasis on findings from the last five years or so. Glass-ionomers are shown to set by an acid-base reaction within 2-3 min and to form hard, reasonably strong materials with acceptable appearance. They release fluoride and are bioactive, so that they gradually develop a strong, durable interfacial ion-exchange layer at the interface with the tooth, which is responsible for their adhesion. Modified forms of glass-ionomers, namely resin-modified glass-ionomers and glass carbomer, are also described and their properties and applications covered. Physical properties of the resin-modified glass-ionomers are shown to be good, and comparable with those of conventional glass-ionomers, but biocompatibility is somewhat compromised by the presence of the resin component, 2 hydroxyethyl methacrylate. Properties of glass carbomer appear to be slightly inferior to those of the best modern conventional glass-ionomers, and there is not yet sufficient information to determine how their bioactivity compares, although they have been formulated to enhance this particular feature.

  2. Clinical Pharmacology of Furosemide in Neonates: A Review

    Directory of Open Access Journals (Sweden)

    Gian Maria Pacifici

    2013-09-01

    Full Text Available Furosemide is the diuretic most used in newborn infants. It blocks the Na+-K+-2Cl− symporter in the thick ascending limb of the loop of Henle increasing urinary excretion of Na+ and Cl−. This article aimed to review the published data on the clinical pharmacology of furosemide in neonates to provide a critical, comprehensive, authoritative and, updated survey on the metabolism, pharmacokinetics, pharmacodynamics and side-effects of furosemide in neonates. The bibliographic search was performed using PubMed and EMBASE databases as search engines; January 2013 was the cutoff point. Furosemide half-life (t1/2 is 6 to 20-fold longer, clearance (Cl is 1.2 to 14-fold smaller and volume of distribution (Vd is 1.3 to 6-fold larger than the adult values. t1/2 shortens and Cl increases as the neonatal maturation proceeds. Continuous intravenous infusion of furosemide yields more controlled diuresis than the intermittent intravenous infusion. Furosemide may be administered by inhalation to infants with chronic lung disease to improve pulmonary mechanics. Furosemide stimulates prostaglandin E2 synthesis, a potent dilator of the patent ductus arteriosus, and the administration of furosemide to any preterm infants should be carefully weighed against the risk of precipitation of a symptomatic patent ductus arteriosus. Infants with low birthweight treated with chronic furosemide are at risk for the development of intra-renal calcifications.

  3. Clinical pharmacology of fentanyl in preterm infants. A review.

    Pacifici, Gian Maria

    2015-06-01

    Fentanyl is a synthetic opioid that is very important in anesthetic practice because of its relatively short time to peak analgesic effect and the rapid termination of action after small bolus doses. The objective of this survey is to review the clinical pharmacology of fentanyl in preterm infants. The bibliographic search was performed using PubMed and EMBASE databases as search engines. In addition, the books Neofax: A manual of drugs used in neonatal care and Neonatal formulary were consulted. Fentanyl is N-dealkylated by CYP3A4 into the inactive norfentanyl. Fentanyl may be administered as bolus doses or as a continuous infusion. In neonates, there is a remarkable interindividual variability in the kinetic parameters. In neonates, fentanyl half-life ranges from 317 minutes to 1266 minutes and in adults it is 222 minutes. Respiratory depression occurs when fentanyl doses are >5 μg/kg. Chest wall rigidity may occur in neonates and occasionally is associated with laryngospasm. Tolerance to fentanyl may develop after prolonged use of this drug. Significant withdrawal symptoms have been reported in infants treated with continuous infusion for 5 days or longer. Fentanyl is an extremely potent analgesic and is the opioid analgesic most frequently used in the neonatal intensive care unit.

    Portal annular pancreas (PAP) is an asymptomatic congenital pancreas anomaly, in which portal and/or mesenteric veins are encased by pancreas tissue. The aim of the study was to determine the role of PAP in pancreatic surgery as well as its management and potential complication, specifically, postoperative pancreatic fistula (POPF).On the basis of a case report, the MEDLINE and ISI Web of Science databases were systematically reviewed up to September 2012. All articles describing a case of PAP were considered.In summary, 21 studies with 59 cases were included. The overall prevalence of PAP was 2.4% and the patients' mean (SD) age was 55.9 (16.2) years. The POPF rate in patients with PAP (12 pancreaticoduodenectomies and 3 distal pancreatectomies) was 46.7% (in accordance with the definition of the International Study Group of Pancreatic Surgery).Portal annular pancreas is a quite unattended pancreatic variant with high prevalence and therefore still remains a clinical challenge to avoid postoperative complications. To decrease the risk for POPF, attentive preoperative diagnostics should also focus on PAP. In pancreaticoduodenectomy, a shift of the resection plane to the pancreas tail should be considered; in extensive pancreatectomy, coverage of the pancreatic remnant by the falciform ligament could be a treatment option.

    The aim of this study was to review the epidemiological and clinical characteristics of neuromyelitis optica (NMO) and the immunopathological mechanisms involved in the neuronal damage. NMO is an inflammatory demyelinating autoimmune disease of the central nervous system that most commonly affects the optic nerves and spinal cord. NMO is thought to be more prevalent among non-Caucasians and where multiple sclerosis (MS) prevalence is low. NMO follows a relapsing course in more than 80-90% of cases, which is more commonly in women. It is a complex disease with an interaction between host genetic and environmental factors and the main immunological feature is the presence of anti-aquaporin 4 (AQP4) antibodies in a subset of patients. NMO is frequently associated with multiple other autoantibodies and there is a strong association between NMO with other systemic autoimmune diseases. AQP4-IgG can cause antibody-dependent cellular cytotoxicity (ADCC) when effector cells are present and complement-dependent cytotoxicity (CDC) when complement is present. Acute therapies, including corticosteroids and plasma exchange, are designed to minimize injury and accelerate recovery. Several aspects of NMO pathogenesis remain unclear. More advances in the understanding of NMO disease mechanisms are needed in order to identify more specific biomarkers to NMO diagnosis.

    Full Text Available Background. Needleless connectors (NC are used on virtually all intravascular devices, providing an easy access point for infusion connection. Colonization of NC is considered the cause of 50% of postinsertion catheter-related infections. Breaks in aseptic technique, from failure to disinfect, result in contamination and subsequent biofilm formation within NC and catheters increasing the potential for infection of central and peripheral catheters. Methods. This systematic review evaluated 140 studies and 34 abstracts on NC disinfection practices, the impact of hub contamination on infection, and measures of education and compliance. Results. The greatest risk for contamination of the catheter after insertion is the NC with 33–45% contaminated, and compliance with disinfection as low as 10%. The optimal technique or disinfection time has not been identified, although scrubbing with 70% alcohol for 5–60 seconds is recommended. Studies have reported statistically significant results in infection reduction when passive alcohol disinfection caps are used (48–86% reduction. Clinical Implications. It is critical for healthcare facilities and clinicians to take responsibility for compliance with basic principles of asepsis compliance, to involve frontline staff in strategies, to facilitate education that promotes understanding of the consequences of failure, and to comply with the standard of care for hub disinfection.

    The cytochrome P450 (CYP) enzymes are membrane-bound hemoproteins that play a pivotal role in the detoxification of xenobiotics, cellular metabolism and homeostasis. Induction or inhibition of CYP enzymes is a major mechanism that underlies drug-drug interactions. CYP enzymes can be transcriptionally activated by various xenobiotics and endogenous substrates through receptor-dependent mechanisms. CYP enzyme inhibition is a principal mechanism for metabolism-based drug-drug interactions. Many chemotherapeutic drugs can cause drug interactions due to their ability to either inhibit or induce the CYP enzyme system. Predictions based on in silico analyses followed by validation have identified several microRNAs that regulate CYPs. Genetic polymorphisms and epigenetic changes in CYP genes may be responsible for inter-individual and inter-ethnic variations in disease susceptibility and the therapeutic efficacy of drugs. Knowledge about the substrates, inducers, inhibitors of CYP isoforms, and the polymorphisms of CYP enzymes may be used as an aid by clinicians to determine therapeutic strategy, and treatment doses for drugs that are metabolized by CYP gene products. The present review is a comprehensive compilation of cytochrome P450 structure, function, pharmacogenetics, and pharmacoepigenetics and clinical significance.

    The aim of this systematic review is to compile and critically evaluate the evidence from randomized clinical trials (RCTs) for the effectiveness of acupuncture using constitutional medicine compared to standard acupuncture. Ten databases were searched through to December 2008 without language restrictions. We also hand-searched nine Korean journals of oriental medicine. We included prospective RCTs of any form of acupuncture with or without electrical stimulation. The included trials had to investigate constitutional medicine. There were no restrictions on population characteristics. Forty-one relevant studies were identified, and three RCTs were included. The methodological quality of the trials was variable. One RCT found Sasang constitutional acupuncture to be superior to standard acupuncture in terms of the Unified PD Rating Scale and freezing gate in Parkinson's disease (PD). Another two RCTs reported favorable effects of eight constitutional acupuncture on pain reduction in patients with herniated nucleus pulposi and knee osteoarthritis. Meta-analysis demonstrated positive results for eight constitutional acupuncture compared to standard acupuncture on pain reduction (weighted mean difference: 10 cm VAS, 1.69, 95% CI 0.85-2.54, P acupuncture in treating pain conditions compared to standard acupuncture. However, the total number of RCTs and the total sample size included in our analysis were too small to draw definite conclusions. Future RCTs should assess larger patient samples with longer treatment periods and appropriate controls.

    Penile fracture is an uncommon Urological emergency. In flaccid state it allows significant degree of deformation without any injury to the vital structures but in erected state it is vulnerable to blunt injury. The tumescent corpora cavernosa may have got injured due to nonphysiological bending of penile shaft. The true incidence of penile fracture is not known even in western countries. It is either under reported or hidden for potential social embracement. We have reviewed all of our cases of penile fracture and has been conducted a retrospective study in the Department of Urology, Bangladesh Medical College, Dhaka. The study period was from October 2001 to January 2006. The sample size was 23. All patients have got classical history of penile fracture. The time between the onset of symptom and seeking of medical care ranges from 02 hours to 07 days. The diagnosis was made on the basis of history and clinical examination only. All the patients were underwent surgery. The potency was well preserved in all of our patients. The local tissue healing process is better among the patients, reported earlier. The overall result is excellent.

  10. A Review of Glass-Ionomer Cements for Clinical Dentistry

    2016-06-01

    Full Text Available This article is an updated review of the published literature on glass-ionomer cements and covers their structure, properties and clinical uses within dentistry, with an emphasis on findings from the last five years or so. Glass-ionomers are shown to set by an acid-base reaction within 2–3 min and to form hard, reasonably strong materials with acceptable appearance. They release fluoride and are bioactive, so that they gradually develop a strong, durable interfacial ion-exchange layer at the interface with the tooth, which is responsible for their adhesion. Modified forms of glass-ionomers, namely resin-modified glass-ionomers and glass carbomer, are also described and their properties and applications covered. Physical properties of the resin-modified glass-ionomers are shown to be good, and comparable with those of conventional glass-ionomers, but biocompatibility is somewhat compromised by the presence of the resin component, 2 hydroxyethyl methacrylate. Properties of glass carbomer appear to be slightly inferior to those of the best modern conventional glass-ionomers, and there is not yet sufficient information to determine how their bioactivity compares, although they have been formulated to enhance this particular feature.

    Primary gastric lymphoma is a rare cancer of the stomach with an indeterminate prognosis. Recently, a series of molecular prognostic markers has been introduced to better describe this clinical entity. This review describes the clinical importance of several oncogenes, apoptotic genes and chromosomal mutations in the initiation and progress of primary non-Hodgkin gastric lymphoma and their effect on patient survival. We also outline the prognostic clinical importance of certain cellular adhesion molecules, such as ICAM and PECAM-1, in patients with gastric lymphoma, and we analyze the correlation of these molecules with apoptosis, angiogenesis, tumour growth and metastatic potential. We also focus on the host-immune response and the impact of Helicobacter pylori infection on gastric lymphoma development and progression. Finally, we explore the therapeutic methods currently available for gastric lymphoma, comparing the traditional invasive approach with more recent conservative options, and we stress the importance of the application of novel molecular markers in clinical practice.

    Full Text Available BACKGROUND: Much controversy exists regarding the clinical efficacy of behavioural and developmental interventions for improving the core symptoms of autism spectrum disorders (ASD. We conducted a systematic review to summarize the evidence on the effectiveness of behavioural and developmental interventions for ASD. METHODS AND FINDINGS: Comprehensive searches were conducted in 22 electronic databases through May 2007. Further information was obtained through hand searching journals, searching reference lists, databases of theses and dissertations, and contacting experts in the field. Experimental and observational analytic studies were included if they were written in English and reported the efficacy of any behavioural or developmental intervention for individuals with ASD. Two independent reviewers made the final study selection, extracted data, and reached consensus on study quality. Results were summarized descriptively and, where possible, meta-analyses of the study results were conducted. One-hundred-and-one studies at predominantly high risk of bias that reported inconsistent results across various interventions were included in the review. Meta-analyses of three controlled clinical trials showed that Lovaas treatment was superior to special education on measures of adaptive behaviour, communication and interaction, comprehensive language, daily living skills, expressive language, overall intellectual functioning and socialization. High-intensity Lovaas was superior to low-intensity Lovaas on measures of intellectual functioning in two retrospective cohort studies. Pooling the results of two randomized controlled trials favoured developmental approaches based on initiative interaction compared to contingency interaction in the amount of time spent in stereotyped behaviours and distal social behaviour, but the effect sizes were not clinically significant. No statistically significant differences were found for: Lovaas versus special

    The nature of the clinical learning environment has a huge impact on student learning. This article reviews current methods available for evaluating the clinical learning environment. Five instruments were identified that measure the clinical learning environment. All of these instruments focus solely on the student perspective of the clinical learning environment. Although gaining student input is important, there are other perspectives that offer valuable insights on the nature of the clinical learning environment. The findings from this integrative review indicate the need for future development and testing of an instrument to evaluate the clinical learning environment from the staff nurse and nurse faculty perspective.

    Over the last few years, clinical trials with BRAF and mitogen-activated protein/extracellular signal-regulated kinase (MEK) inhibitors have shown significant clinical activity in melanoma, but only a fraction of patients respond to these therapies, and development of resistance is frequent. This has prompted a large set of preclinical studies looking at several new combinatorial approaches of pathway- or target-specific inhibitors. At least five main drug association strategies have been verified in vitro and in preclinical models. The most promising include: i) vertical targeting of either MEK or phosphoinositide-3 kinase (PI3K)/mammalian target of rapamycin (mTOR) pathways, or their combined blockade; ii) association of receptor tyrosine kinases (RTKs) inhibitors with other pro-apoptotic strategies; iii) engagement of death receptors in combination with MEK-, mTOR/PI3K-, histone deacetylase (HDAC)-inhibitors, or with anti-apoptotic molecules modulators; iv) strategies aimed at blocking anti-apoptotic proteins belonging to B-cell lymphoma (Bcl-2) or inhibitors of apoptosis (IAP) families associated with MEK/BRAF/p38 inhibition; v) co-inhibition of other molecules important for survival [proteasome, HDAC and Signal transducers and activators of transcription (Stat)3] and the major pathways activated in melanoma; vi) simultaneous targeting of multiple anti-apoptotic molecules. Here we review the anti-melanoma efficacy and mechanism of action of the above-mentioned combinatorial strategies, together with the potential clinical application of the most promising studies that may eventually lead to therapeutic benefit.

    Full Text Available Clinical education is an essential component of the education of nursing students. However clinical nursing education in Ghana is currently facing challenges of poor working relations between hospitals and health training institutions, inadequate preceptor preparations, and inadequate faculty supervisions. Although the dominant clinical education model used in Ghana is the preceptorship model, health service and education industries are faced with challenges of lack of qualified staff, inadequately prepared preceptors, and inadequate supervision from faculty. These challenges undermine the effectiveness of the clinical learning environment and the use of the preceptorship model. The purpose of this paper was to review preceptorship and clinical teaching partnership (CTP and make recommendations for improving clinical nursing education in Ghana. A literature review was undertaken through a search of databases that included Google Scholar, EBSCOhost, CINAHL, and HINARI. A literature review identified advantages for using clinical teaching partnership (CTP in clinical nursing education in Ghana. Recommendations were made for the use of CTP in Ghana.

    Struggling medical trainees pose a challenge to clinical teachers, since these learners warrant closer supervision that is time-consuming and competes with time spent on patient care. Clinical teachers’ perception that they are ill equipped to address learners’ difficulties efficiently may lead to delays or even lack of remediation for these learners. Because of the paucity of evidence to guide best practices in remediation, the best approach to guide clinical teachers in the field remains to be established. We aimed to present a synthetic review of the empirical evidence and theory that may guide clinical teachers in their daily task of supervising struggling learners, reviewing current knowledge on the challenges and solutions that have been identified and explored. A computerized literature search was performed using Medline, Embase, Education Resources Information Center, and Education Source, after which final articles were selected based on relevance. The literature reviewed provided best evidence for clinical teachers to address learners’ difficulties, which is presented in the order of the four steps inherent to the clinical approach: 1) detecting a problem based on a subjective impression, 2) gathering and documenting objective data, 3) assessing data to make a diagnosis, and 4) planning remediation. A synthesized classification of pedagogical diagnoses is also presented. This review provides an outline of practical recommendations regarding the supervision and management of struggling learners up to the remediation phase. Our findings suggest that future research and faculty development endeavors should aim to operationalize remediation strategies further in response to specific diagnoses, and to make these processes more accessible to clinical teachers in the field.

    Full Text Available Porcine respiratory disease complex (PRDC is a major economic problem for swine producers world-wide. Pharmacodynamic, pharmacokinetics and clinical efficacy of florfenicol oral formulations in domestic animals were evaluated. For this purpose the systematic review and meta-analysis were done. In vitro efficacy of florfenicol showed that this drug is highly effective against most important respiratory pathogens. All these facts are shown in our survey. Three studies in pigs were relevant to include in the meta-analysis, which showed that results in the florfenicol group were better than in comparative control groups in all observed parameters: clinical signs, lung lesions and resolution of Actinobacillus pleuropneumoniae (P<0,001. A second meta-analysis with 7 studies showed that the usage of florfenicol reduces mortality in pig herds with PRDC (P<0.05. Other field trials in pigs using florfenicol oral forms where reviewed. After treatment with florfenicol oral solution there was a significant drop of mortality in both groups of pigs (P<0.01; eg. one using florfenicol oral solution in treating PRDC (n=85 and another mixed pneumoenteric infection (n=54. Analysis of data when using premix in pigs (n=118 also suggests that a medicated premix has a favorable anti-infectious effect on pigs, irrespective of the group of animals or the evolution stage of the disease. Finally, favorable effect of florfenicol in treating swine ileitis was also presented. Regarding their pharmacokinetics, in vitro and clinical efficacy of florfenicol oral forms, they should be considered as a powerful tool for combating complex infections that are frequently met in intensive animal production.

    This paper is a narrative review of normal cervical alignment, methods for quantifying alignment, and how alignment is associated with cervical deformity, myelopathy, and adjacent-segment disease (ASD), with discussions of health-related quality of life (HRQOL). Popular methods currently used to quantify cervical alignment are discussed including cervical lordosis, sagittal vertical axis, and horizontal gaze with the chin-brow to vertical angle. Cervical deformity is examined in detail as deformities localized to the cervical spine affect, and are affected by, other parameters of the spine in preserving global sagittal alignment. An evolving trend is defining cervical sagittal alignment. Evidence from a few recent studies suggests correlations between radiographic parameters in the cervical spine and HRQOL. Analysis of the cervical regional alignment with respect to overall spinal pelvic alignment is critical. The article details mechanisms by which cervical kyphotic deformity potentially leads to ASD and discusses previous studies that suggest how postoperative sagittal malalignment may promote ASD. Further clinical studies are needed to explore the relationship of cervical malalignment and the development of ASD. Sagittal alignment of the cervical spine may play a substantial role in the development of cervical myelopathy as cervical deformity can lead to spinal cord compression and cord tension. Surgical correction of cervical myelopathy should always take into consideration cervical sagittal alignment, as decompression alone may not decrease cord tension induced by kyphosis. Awareness of the development of postlaminectomy kyphosis is critical as it relates to cervical myelopathy. The future direction of cervical deformity correction should include a comprehensive approach in assessing global cervicalpelvic relationships. Just as understanding pelvic incidence as it relates to lumbar lordosis was crucial in building our knowledge of thoracolumbar deformities, T

    2001-01-01

    Epidemiologic surveys of temporomandibular disorders (TMD) have demonstrated that a considerable proportion of the population--up to 5% or 6%--will experience persistent pain severe enough to seek treatment. Unfortunately, the current diagnostic classification of craniofacial muscle pain is based on descriptions of signs and symptoms rather than on knowledge of pain mechanisms. Furthermore, the pathophysiology and etiology of craniofacial muscle pain are not known in sufficient detail to allow causal treatment. Many hypotheses have been proposed to explain cause-effect relationships; however, it is still uncertain what may be the cause of muscle pain and what is the effect of muscle pain. This article reviews the literature in which craniofacial muscle pain has been induced by experimental techniques in animals and human volunteers and in which the effects on somatosensory and motor function have been assessed under standardized conditions. This information is compared to the clinical correlates, which can be derived from the numerous cross-sectional studies in patients with craniofacial muscle pain. The experimental literature clearly indicates that muscle pain has significant effects on both somatosensory and craniofacial motor function. Typical somatosensory manifestations of experimental muscle pain are referred pain and increased sensitivity of homotopic areas. The craniofacial motor function is inhibited mainly during experimental muscle pain, but phase-dependent excitation is also found during mastication to reduce the amplitude and velocity of jaw movements. The underlying neurobiologic mechanisms probably involve varying combinations of sensitization of peripheral afferents, hyperexcitability of central neurons, and imbalance in descending pain modulatory systems. Reflex circuits in the brain stem seem important for the adjustment of sensorimotor function in the presence of craniofacial pain. Changes in somatosensory and motor function may therefore be

    Objectives To determine the diagnostic value of diascopy and other non-invasive clinical aids on recent differential diagnosis algorithms of oral mucosal pigmentations affecting subjects of any age. Material and Methods Data Sources: this systematic review was conducted by searching PubMed, Scopus, Dentistry & Oral Sciences Source and the Cochrane Library (2000-2015); Study Selection: two reviewers independently selected all types of English articles describing differential diagnosis algorithms of oral pigmentations and checked the references of finally included papers; Data Extraction: one reviewer performed the data extraction and quality assessment based on previously defined fields while the other reviewer checked their validity. Results Data Synthesis: eight narrative reviews and one single case report met the inclusion criteria. Diascopy was used on six algorithms (66.67%) and X-ray was included once (11.11%; 44.44% with text mentions); these were considered helpful tools in the diagnosis of intravascular and exogenous pigmentations, respectively. Surface rubbing was described once in the text (11.11%). Conclusions Diascopy was the most applied method followed by X-ray and surface rubbing. The limited scope of these procedures only makes them useful when a positive result is obtained, turning biopsy into the most recommended technique when diagnosis cannot be established on clinical grounds alone. Key words:Algorithm, differential diagnosis, flow chart, oral mucosa, oral pigmentation, systematic review. PMID:27703615

    The Integrated Data Collection Analysis (IDCA) program conducted a final program review at the Department of Homeland Security on September 12, 2012. The review was focused on the results of the program over the complete performance period. A summary presentation delineating the accomplished tasks started the meeting, followed by technical presentations on various issues that arose during the performance period. The presentations were completed with a statistical evaluation of the testing results from all the participants in the IDCA Proficiency Test study. The meeting closed with a discussion of potential sources of funding for continuing work to resolve some of these technical issues. This effort, funded by the Department of Homeland Security (DHS), put the issues of safe handling of these materials in perspective with standard military explosives. The study added Small-Scale Safety and Thermal (SSST) testing results for a broad suite of different HMEs to the literature, and suggested new guidelines and methods to develop safe handling practices for HMEs. Each participating testing laboratory used identical test materials and preparation methods wherever possible. Note, however, the test procedures differ among the laboratories. The results were compared among the laboratories and then compared to historical data from various sources. The testing performers involved were Lawrence Livermore National Laboratory (LLNL), Los Alamos National Laboratory (LANL), Naval Surface Warfare Center, Indian Head Division (NSWC IHD), Sandia National Laboratories (SNL), and Air Force Research Laboratory, Tyndall AFB (AFRL/RXQL). These tests were conducted as a proficiency study in order to establish some consistency in test protocols, procedures, and experiments and to compare results when these testing variables cannot be made consistent.

    Full Text Available Investigation in the field of Alzheimer´s disease (AD, the commonest cause of dementia, has been very active in recent years and it may be difficult for the clinician to keep up with all the innovations and to be aware of the implications they have in clinical practice. The authors, thus, reviewed recent literature on the theme in order to provide the clinician with an updated overview, intended to support decision-making on aspects of diagnosis and management. This article begins to focus on the concept of AD and on its pathogenesis. Afterwards, epidemiology and non-genetic risk factors are approached. Genetics, including genetic risk factors and guidelines for genetic testing, are mentioned next. Recommendations for diagnosis of AD, including recently proposed criteria, are then reviewed. Data on the variants of AD is presented. First approach to the patient is dealt with next, followed by neuropsychological evaluation. Biomarkers, namely MRI, SPECT, FDG PET, PiB PET, CSF tau and Aβ analysis, as well as available data on their diagnostic accuracy, are also discussed. Factors predicting rate of disease progression are briefly mentioned. Finally, non-pharmacological and pharmacological treatments, including established and emerging drugs, are addressed.

    Prostate cancer has come to share the oncological centrestage among male cancers. The availability of Serum Prostate Specific Antigen, PSA, as a marker has encouraged it's use to diagnose both cancer and cancer recurrence. Some clarity is required about its precise role in clinical practice. The available literature on Prostate Specific Antigen was reviewed; Articles were reviewed for content, applicability to the problem at hand, availability of data about sensitivity and specificity of values, refinements in measurements and finally for impact of screening programmes using these values on survival and quality of life. The data in the literature was critically re-evaluated and analysed to draw reasonable conclusions. Serum PSA measurements show variable reliability when it comes to diagnosis of Prostate cancer, given the dynamics of PSA physiology. Surrogate measures like PSA density, PSA velocity, free-to-complexed PSA ratio, percentage Pro-PSA, etc., have been used to improve the predictive utility of this assay for Prostate cancer. The ability of PSA to detect those cancers that will cost life, and thereby permit early curative treatment, is as yet unclear. It's most definitive role appears to be in diagnosing recurrences after adequate surgical treatment, and in evaluating response to treatment.

  10. Classification and clinical features of headache disorders in Pakistan: a retrospective review of clinical data.

    Directory of Open Access Journals (Sweden)

    Muhammed Murtaza

    Full Text Available BACKGROUND: Morbidity associated with primary headache disorders is a major public health problem with an overall prevalence of 46%. Tension-type headache and migraine are the two most prevalent causes. However, headache has not been sufficiently studied as a cause of morbidity in the developing world. Literature on prevalence and classification of these disorders in South Asia is scarce. The aim of this study is to describe the classification and clinical features of headache patients who seek medical advice in Pakistan. METHODS AND RESULTS: Medical records of 255 consecutive patients who presented to a headache clinic at a tertiary care hospital were reviewed. Demographic details, onset and lifetime duration of illness, pattern of headache, associated features and family history were recorded. International Classification of Headache Disorders version 2 was applied. 66% of all patients were women and 81% of them were between 16 and 49 years of age. Migraine was the most common disorder (206 patients followed by tension-type headache (58 patients, medication-overuse headache (6 patients and cluster headache (4 patients. Chronic daily headache was seen in 99 patients. Patients with tension-type headache suffered from more frequent episodes of headache than patients with migraine (p<0.001. Duration of each headache episode was higher in women with menstrually related migraine (p = 0.015. Median age at presentation and at onset was lower in patients with migraine who reported a first-degree family history of the disease (p = 0.003 and p<0.001 respectively. CONCLUSIONS/SIGNIFICANCE: Patients who seek medical advice for headache in Pakistan are usually in their most productive ages. Migraine and tension-type headache are the most common clinical presentations of headache. Onset of migraine is earlier in patients with first-degree family history. Menstrually related migraine affects women with headache episodes of longer duration than other patients

  11. 2013 Nutrition Risk Research Plan Review Final Report. Research Plan Review for: The Risk Factor of Inadequate Nutrition

    Science.gov (United States)

    2014-01-01

    The 2013 Nutrition Risk Standing Review Panel (from here on referred to as the SRP) was impressed by the degree of progress the nutrition discipline has made with the research plan presented since the 2012 Nutrition Risk SRP WebEx/teleconference. The scientists and staff associated with the nutrition discipline have, in addition, continued their impressive publication track record. Specifically the SRP found that the novel and important progress in the ocular health research area (Gap N7.3) represents an important advance in understanding the etiology and potential countermeasures for this condition and thinks that the work will not only be valuable for vision, but may have implications for cardiovascular health, as well. The SRP also considered the bone countermeasure data presented a potentially valuable tool for investigating bone metabolism under the unique conditions of space travel, specifically the innovation of variable use of stable Ca isotopes for bone synthesis and equal contribution for bone to investigate bone metabolism, as well as, the impact of the advanced resistive exercise device (ARED) on body composition during spaceflight. Finally, the SRP considers the planned Integrated Nutrition task to be an important and necessary strategic part of the research plan. The SRP is concerned that the risks observed in previous research on Low Earth Orbit (LEO) may not capture all the risks of longer duration flight beyond LEO. In particular, the SRP believes that there may be a much greater likelihood of an intensified chronic inflammatory response compared to the very minimal evidence seen to date and that modest effects seen in LEO, such as the reduction in appetite, may not predict an absence in longer duration flight out of LEO. The added complications of longer duration flight, greater bio-behavioral stress, radiation exposure, poorer communication, and inability to respond to unforeseen exigencies may create different risks. Thus, preparation for

    Killam Laura A

    2012-11-01

    Full Text Available Abstract Background Nursing education necessitates vigilance for clinical safety, a daunting challenge given the complex interchanges between students, patients and educators. As active learners, students offer a subjective understanding concerning safety in the practice milieu that merits further study. This study describes the viewpoints of senior undergraduate nursing students about compromised safety in the clinical learning environment. Methods Q methodology was used to systematically elicit multiple viewpoints about unsafe clinical learning from the perspective of senior students enrolled in a baccalaureate nursing program offered at multiple sites in Ontario, Canada. Across two program sites, 59 fourth year students sorted 43 theoretical statement cards, descriptive of unsafe clinical practice. Q-analysis identified similarities and differences among participant viewpoints yielding discrete and consensus perspectives. Results A total of six discrete viewpoints and two consensus perspectives were identified. The discrete viewpoints at one site were Endorsement of Uncritical Knowledge Transfer, Non-student Centered Program and Overt Patterns of Unsatisfactory Clinical Performance. In addition, a consensus perspective, labelled Contravening Practices was identified as responsible for compromised clinical safety at this site. At the other site, the discrete viewpoints were Premature and Inappropriate Clinical Progression, Non-patient Centered Practice and Negating Purposeful Interactions for Experiential Learning. There was consensus that Eroding Conventions compromised clinical safety from the perspective of students at this second site. Conclusions Senior nursing students perceive that deficits in knowledge, patient-centered practice, professional morality and authenticity threaten safety in the clinical learning environment. In an effort to eradicate compromised safety associated with learning in the clinical milieu, students and educators

    2001-05-01

    Successful treatment of tooth luxations, crown fractures, and root fractures is often compromised by the emergency nature of the injury. Precise radiographic and clinical evaluation is required to facilitate healing and treatment selection. While traditional treatment protocols indicate that dental injuries implying pulpal ischemia require immediate endodontic therapy to avoid healing complications, the clinical investigations discussed herein suggest that a variety of etiologies for pulp survival/pulp necrosis exist. This article discusses the long-term prognosis of pulp necrosis following traumatic dental injuries, and clinical and radiographic criteria for its diagnosis.

    Del Sorbo, Francesca; Albanese, Alberto

    2015-12-01

    Botulinum neurotoxins (BoNTs) are used to achieve therapeutic benefit in focal dystonia. An expert panel recently reviewed published evidence on the efficacy of BoNTs for the treatment of focal dystonias and produced recommendations for clinical practice. Another panel reviewed the clinimetric properties of rating scales for dystonia and produced recommendations for current usage and future directions. Considering that the strength of evidence derives not only from the quality of the study design, but also from usage of validated outcome measures, we combined the information provided by these two recent reviews and assessed the appropriateness of the rating instruments used in clinical trials on BoNT treatment in focal dystonia. Data sources included all the publications on BoNT treatment for focal dystonias reviewed by the recent evidence-based analysis. We reviewed all rating instruments used to assess primary and secondary outcome following BoNT treatment. The publications were allocated into five topics according to the focal dystonia type reviewed in the meta-analysis: blepharospasm, oromandibular dystonia, cervical dystonia, upper limb dystonia, and laryngeal dystonia. For each topic, papers were divided, according to the terminology used in the meta-analysis, into placebo-controlled, active comparator and methodological or uncontrolled. For each topic we identified the rating tools used in each study class and annotated which were the mostly used in each focal dystonia type. Outcome measures included tools related to motor and non-motor features, such as pain and depression, and functional as well as health-related quality of life features. Patient- and investigator-reported outcomes were also included. Rating instruments were classified as recommended, suggested, listed or not included, based on recommendations produced by the rating scale task force. Both primary and secondary outcome measures were assessed. As a final step we compared current practice, as

    Full Text Available ABSTRACT INTRODUCTION: The esthetic balance of the face results from harmonic and symmetrical facial proportions. The literature describes several methods for lower-third facial analysis, but lacks a simple and practical method. OBJECTIVE: To review the methods of analysis of the ideal projections of the chin based on soft tissues, showing the advantages and disadvantages of each. METHODS: Literature review through the PubMed database. RESULTS: The following methods for chin analysis based on soft tissues were reviewed: Gonzalles-Ulloa, Goode, Merrifield, Silver, Legan, Gibson & Calhoun, cervicomentual angle, and mentocervical angle. CONCLUSION: An adequate analysis of the proportions of the face and facial disharmony is essential for the correct indication of the necessary procedures and good surgical outcome. The authors propose an algorithm to facilitate the indication for chin augmentation surgery.

  17. Is there a way for clinical teachers to assist struggling learners? A synthetic review of the literature

    Directory of Open Access Journals (Sweden)

    2017-01-01

    Full Text Available Elisabeth Boileau,1 Christina St-Onge,2 Marie-Claude Audétat3 1Department of Family and Emergency Medicine, 2Department of Medicine, Université de Sherbrooke, Sherbrooke, QC, Canada; 3Unité des Internistes Généralistes et Pédiatres, Université de Genève, Geneva, Switzerland Abstract: Struggling medical trainees pose a challenge to clinical teachers, since these learners warrant closer supervision that is time-consuming and competes with time spent on patient care. Clinical teachers’ perception that they are ill equipped to address learners’ difficulties efficiently may lead to delays or even lack of remediation for these learners. Because of the paucity of evidence to guide best practices in remediation, the best approach to guide clinical teachers in the field remains to be established. We aimed to present a synthetic review of the empirical evidence and theory that may guide clinical teachers in their daily task of supervising struggling learners, reviewing current knowledge on the challenges and solutions that have been identified and explored. A computerized literature search was performed using Medline, Embase, Education Resources Information Center, and Education Source, after which final articles were selected based on relevance. The literature reviewed provided best evidence for clinical teachers to address learners’ difficulties, which is presented in the order of the four steps inherent to the clinical approach: 1 detecting a problem based on a subjective impression, 2 gathering and documenting objective data, 3 assessing data to make a diagnosis, and 4 planning remediation. A synthesized classification of pedagogical diagnoses is also presented. This review provides an outline of practical recommendations regarding the supervision and management of struggling learners up to the remediation phase. Our findings suggest that future research and faculty development endeavors should aim to operationalize remediation

    2005-01-01

    Objective To identify features of clinical decision support systems critical for improving clinical practice. Design Systematic review of randomised controlled trials. Data sources Literature searches via Medline, CINAHL, and the Cochrane Controlled Trials Register up to 2003; and searches of reference lists of included studies and relevant reviews. Study selection Studies had to evaluate the ability of decision support systems to improve clinical practice. Data extraction Studies were assessed for statistically and clinically significant improvement in clinical practice and for the presence of 15 decision support system features whose importance had been repeatedly suggested in the literature. Results Seventy studies were included. Decision support systems significantly improved clinical practice in 68% of trials. Univariate analyses revealed that, for five of the system features, interventions possessing the feature were significantly more likely to improve clinical practice than interventions lacking the feature. Multiple logistic regression analysis identified four features as independent predictors of improved clinical practice: automatic provision of decision support as part of clinician workflow (P < 0.00001), provision of recommendations rather than just assessments (P = 0.0187), provision of decision support at the time and location of decision making (P = 0.0263), and computer based decision support (P = 0.0294). Of 32 systems possessing all four features, 30 (94%) significantly improved clinical practice. Furthermore, direct experimental justification was found for providing periodic performance feedback, sharing recommendations with patients, and requesting documentation of reasons for not following recommendations. Conclusions Several features were closely correlated with decision support systems' ability to improve patient care significantly. Clinicians and other stakeholders should implement clinical decision support systems that incorporate these

    Full Text Available Background. Itch (pruritus is a sensitive state that provokes the desire to scratch. It is not only a common symptom of skin diseases but it also occurs in some systemic diseases. Clinical studies on the efficacy of the acupuncture therapy in alleviating itch are increasing, while systematic reviews assessing the efficacy of acupuncture therapy are still lacking. Objective. This systematic review aims to assess the effectiveness of acupuncture therapy for itch. Materials and Methods. A comprehensive literature search of eight databases was performed up to June 2014, and randomized controlled trials which compared acupuncture therapy and placebo acupuncture or no treatment group were identified. Accordingly, a meta-analysis was conducted. Results. This review included three articles of randomized controlled trials (RCTs from a total of 2530 articles. The results of Meta-analysis showed that acupuncture therapy was effective to alleviate itch compared with placebo acupuncture and no treatment group. Conclusion. Based on the findings of this systematic review, we cautiously suggest that acupuncture therapy could improve the clinical efficacy of itch. However, this conclusion needs more studies on various ethnic samples to confirm our final conclusion.

    Citrus bergamia Risso et Poiteau ("Bergamot") originated from the Mediterranean ecoregion (southern Italy, Calabria). Bergamot essential oil (BEO) is used in perfumes, cosmetics, and for stress reduction. Juice from C. bergamia has been used for hyperlipidemia. We evaluated literature published on C. bergamia clinical applications. Clinical trials on C. bergamia not combined with other substances, published in English, were searched. We selected ten articles, six describing BEO effects on stress, three reporting effects of polyphenolic fraction of C. bergamia juice in hyperlipidemia and the last describing BEO effects in chronic psoriasis. Clinical studies were analyzed following Consolidated Standards of Reporting Trials for herbal therapy. Studies were conducted on small sample sizes and not have high quality level. Analysis indicates that BEO aromatherapy could be safe and useful to reduce stress symptoms. One study suggests its potential supportive role in ultraviolet B therapy against psoriasis. Supplementation with polyphenols from bergamot juice reduces plasma lipids and improves lipoprotein profile in moderate hyperlipidemia. Effectiveness and safety of C. bergamia cannot be definitively drawn because of publication bias and low quality level of the majority of studies. Further large-scale trials with rigorous design are required to define the role of C. bergamia in clinical practice. Copyright © 2016 John Wiley & Sons, Ltd.

    low risk of bias trials evaluating a clinically relevant outcome were prematurity and respiratory illness. Finally, we created and validated the online searchable database using 13 recent systematic reviews. Of the 38 high dose trials identified by the systematic review, 36 (94.7% could be found within the database. When compared with the search strategy reported in each systematic review, use of the database reduced the number of full papers to assess for eligibility by 85.2% (±13.4%. Conclusion. The pediatric vitamin D field is highly active, with a significant increase in trials evaluating non-classical diseases and outcomes. Despite the large overall number there are few high quality trials of sufficient size to provide answers on clinical efficacy of high-dose vitamin D. An open access online searchable data should assist end users in the rapid and comprehensive identification and evaluation of trials relevant to their population or question of interest.

    Edgecombe, Kay; Jennings, Michele; Bowden, Margaret

    2013-02-01

    This paper reviews the sparse literature about international nursing students' clinical learning experiences, and also draws on the literature about international higher education students' learning experiences across disciplines as well as nursing students' experiences when undertaking international clinical placements. The paper aims to identify factors that may impact international nursing students' clinical learning with a view to initiating further research into these students' attributes and how to work with these to enhance the students' clinical learning. Issues commonly cited as affecting international students are socialisation, communication, culture, relationships, and unmet expectations and aspirations. International student attributes tend to be included by implication rather than as part of the literature's focus. The review concludes that recognition and valuing of international nursing students' attributes in academic and clinical contexts are needed to facilitate effective strategies to support their clinical practice in new environments.

    1997-11-01

    The adult classification of dysarthria correlating with the pathophysiology of the motor systems is usually applied to classify acquired childhood dysarthria. However, the validity of this adult model for children has not been studied systematically. All studies pertaining to analysis of speech features in acquired childhood dysarthria published since 1980 were reviewed. Studies were classified on the basis of neuroradiologic evidence of lesion site and associated motor disorder. This review demonstrates that knowledge of acquired childhood dysarthria is based on a limited number of single case studies, most of which pertain to dysarthria occurring after resection of cerebellar tumor. Definite similarities to adult dysarthria were not evident. Some similarity to acquired childhood dysarthria due to basal ganglia lesions was detected. We conclude that acquired childhood dysarthria requires its own classification.

    Ameloblastoma is a rare odontogenic neoplasm of the mandible and maxilla, with multiple histologic variants, and high recurrence rates if improperly treated. The current mainstay of treatment is wide local excision with appropriate margins and immediate reconstruction. Here we review the ameloblastoma literature, using the available evidence to highlight the change in management over the past several decades. In addition, we explore the recent molecular characterization of these tumors which may point towards new potential avenues of personalized treatment.

    2014-11-01

    Synsepalum dulcificum or the "miracle fruit" is well known for its taste-modifying ability. The aim of this review was to assess the published medically beneficial as well as potential characteristics of this fruit. A search in three databases, including PubMed, ScienceDirect, and Google Scholar, was made with appropriate keywords. The resulting articles were screened in different stages based on the title, abstract, and content. A total of nine articles were included in this review. This review summarized the findings of previously published studies on the effects of miracle fruit. The main studied characteristic of the fruit was its effect on the taste receptors, resulting in the sweet sensation when substances with acidic content were ingested. This effect was shown to be related to a glycoprotein called "miraculin." Other beneficial characteristics of this fruit were its antioxidant and anticancer abilities that are due to the various amides existing in the miracle fruit. Apart from the above, the other observed effect of this fruit was its antidiabetic effect that was tested in rats. Further studies should be conducted to establish the findings. The miracle fruit can be a healthy additive due to its unique characteristics, including sour taste sensation modification as well as its antioxidant and antidiabetic effects.

    Directory of Open Access Journals (Sweden)

    Geraldo Bezerra da Silva Junior

    2015-02-01

    Full Text Available Leprosy is a chronic disease caused by Mycobacterium leprae, highly incapacitating, and with systemic involvement in some cases. Renal involvement has been reported in all forms of the disease, and it is more frequent in multibacillary forms. The clinical presentation is variable and is determined by the host immunologic system reaction to the bacilli. During the course of the disease there are the so called reactional states, in which the immune system reacts against the bacilli, exacerbating the clinical manifestations. Different renal lesions have been described in leprosy, including acute and chronic glomerulonephritis, interstitial nephritis, secondary amyloidosis and pyelonephritis. The exact mechanism that leads to glomerulonephritis in leprosy is not completely understood. Leprosy treatment includes rifampicin, dapsone and clofazimine. Prednisone and non-steroidal anti-inflammatory drugs may be used to control acute immunological episodes.

    Full Text Available Catatonia is a severe motor syndrome with an estimated prevalence among psychiatric inpatients of about 10%. At times, it is life-threatening especially in its malignant form when complicated by fever and autonomic disturbances. Catatonia can accompany many different psychiatric illnesses and somatic diseases. In order to recognize the catatonic syndrome, apart from thorough and repeated observation, a clinical examination is needed. A screening instrument, such as the Bush-Francis Catatonia Rating Scale, can guide the clinician through the neuropsychiatric examination. Although severe and life-threatening, catatonia has a good prognosis. Research on the treatment of catatonia is scarce, but there is overwhelming clinical evidence of the efficacy of benzodiazepines, such as lorazepam, and electroconvulsive therapy.

    Federal investment in health information technology has incentivized the adoption of electronic health record systems by physicians and health care organizations; the result has been a massive rise in the collection of patient data in electronic form (i.e. "Big Data"). Health care systems have leveraged Big Data for quality and performance improvements using analytics-the systematic use of data combined with quantitative as well as qualitative analysis to make decisions. Analytics have been utilized in various aspects of health care including predictive risk assessment, clinical decision support, home health monitoring, finance, and resource allocation. Visual analytics is one example of an analytics technique with an array of health care and research applications that are well described in the literature. The proliferation of Big Data and analytics in health care has spawned a growing demand for clinical informatics professionals who can bridge the gap between the medical and information sciences.

    Magnetic resonance imaging (MRI) provides anatomic images and morphometric characterization of disease, whereas magnetic resonance spectroscopy (MRS) provides metabolite/biochemical information about tissues non-invasively in vivo. MRS has been used clinically for more than two decades. The major applications of this advanced MRI tool are in the investigation of neurological and neurosurgical disorders. MRS has also been used in the evaluation of the prostate gland and muscle tissue, but these applications will not be addressed in this review. The aim of this review is to attempt to introduce the technique, review the metabolites and literature, as well as briefly describe our clinical experience.

    Coulouvrat, C; Dondey-Nouvel, L

    1999-07-01

    We assessed the overall safety profile of amisulpride based on the results from 11 clinical studies performed in patients suffering from schizophrenia with predominance of positive or negative symptoms. A total of 1933 patients were randomly assigned to treatment with amisulpride (n = 1247) or haloperidol (n = 309), risperidone (n = 113), flupentixol (n = 62) and placebo (n = 202). Safety data collection was performed using open reporting, UKU scales or specific extrapyramidal side-effect scales; electrocardiogram recording and vital signs examination; laboratory data collection. Amisulpride demonstrated a satisfactory global safety profile in the range of doses usually prescribed. The number of patients having at least one extrapyramidal side-effect was higher in haloperidol patients compared with both amisulpride and risperidone patients (50% versus 30% in the two latter groups). For endocrine events, a similar rate was observed between amisulpride and risperidone groups (4% versus 6%, respectively) versus 1% in the haloperidol group. Electrocardiogram results were satisfactory, confirmed by the absence of cardiovascular events. The overall laboratory safety profile of amisulpride did not show clinically relevant abnormalities in liver function tests nor haematological abnormalities. Our extensive clinical data confirm the satisfactory safety profile of amisulpride which is superior to standard reference compounds.

    2016-01-01

    Background Inadequate epidemiologic investigations of the paranasal sinuses malignancies prompted this retrospective study with special emphasis on a major group of 111 tumors. Material and Methods Clinical records of 111 patients with histologically confirmed malignant tumors of the paranasal sinuses were investigated retrospectively from April 2000 to January 2012. Collection of data included demographic information, clinical manifestations, treatment plans, and histopathology of the tumor. Results There were 69 (62.16%) male and 42 (37.83%) female patients (male-to-female ratio of 1.6:1), with a median age of 49±12.2 years (range 21 to 88 years). A high level of occurrence was noticed in the fifth (26.3%) decade of life. The most frequent histological types were squamous cell carcinoma (43.5%) and adenoid cystic carcinoma (19%). Among clinical manifestations, nasal obstruction was the most frequent followed by diplopia, and facial swelling. Fifty three patients (47.74%) were treated with combined approach of surgery and radiation therapy. Conclusions Paranasal sinuses malignancies are rare conditions with nonspecific symptoms which make early diagnosis of the lesions more challenging. The optimal therapeutic protocol for patients suffering from these tumors is still a somewhat controversial entity and requires further studies. Key words:Paranasal sinuses, malignancy, surgery,radiotherapy. PMID:27475693

    2010-05-01

    The ethical guidelines for clinical studies were revised in 2008 and enforced in April 2009. This was the second revision but first regular revision and largely reviewed. In particular, articles under the purview of the Institutional Review Board (IRB) for clinical studies are reviewed and enhanced. This additional role further increases the authority of the IRB, and those who fix the IRB must exhibit the activity of the IRB to the public and report to the MHLW annually. The provision of compensation for clinical studies on the evaluation of drugs and medical devices has been added to this version of the ethical guidelines. The compensation for interventional clinical studies using drugs and medical devices has not yet been decided, similar to "chiken," which is defined in pharmaceutical affairs laws (PAL). Since April 2009, some insurance offices have started offering special insurance covers for clinical studies. New registration rules have been established for clinical studies. Moreover, there is now a database for clinical study registration called "Japan Primary Registries Network (JPRN)," which is certified by WHO. This database comprises 3 open databases, which were originally independent, related to clinical trials in Japan. They are however under the purview of the National Institute of Public Health. This institution works in collaboration with the "International Clinical Trials Registry Platform (ICTRP)" of WHO.

  20. W-519 Sagebrush Mitigation Project FY-2004 Final Review and Status

    Energy Technology Data Exchange (ETDEWEB)

    Durham, Robin E.; Sackschewsky, Michael R.

    2004-09-30

    This report summarizes activities conducted as mitigation for loss of sagebrush-steppe habitats due to Project W-519, the construction of the infrastructure for the Tank Waste Remediation System Vitrification Plant. The focus of this report is to provide a review and final status of mitigation actions performed through FY2004. Data collected since FY1999 have been included where appropriate. The Mitigation Action Plan (MAP) for Project W-519 prescribed three general actions to be performed as mitigation for the disturbance of approximately 40 ha (100 acres) of mature sagebrush-steppe habitat. These actions included: (1) transplanting approximately 130,000 sagebrush seedlings on the Fitzner-Eberhardt Arid Lands Ecology Reserve (ALE); (2) rectification of the new transmission line corridor via seeding with native grasses and sagebrush; and (3) research on native plant species with a goal of increasing species diversity in future mitigation or restoration actions. Nearly 130,000 Wyoming big sagebrush seedlings where planted on ALE during FY2000 and FY2001. About 39,000 of those seedlings were burned during the 24-Command Fire of June 2000. The surviving and subsequent replanting has resulted in about 91,000 seedlings that were planted across four general areas on ALE. A 50% survival rate at any monitoring period was defined as the performance standard in the MAP for this project. Data collected in 2004 indicate that of the over 5000 monitored plants, 51.1% are still alive, and of those the majority are thriving and blooming. These results support the potential for natural recruitment and the ultimate goal of wildlife habitat replacement. Thus, the basic performance standard for sagebrush survival within the habitat compensation planting has been met. Monitoring activities conducted in 2004 indicate considerable variation in seedling survival depending on the type of plant material, site conditions, and to a lesser extent, treatments performed at the time of planting

    Full Text Available Abstract Background In the past forty years, many gains have been made in our understanding of the concept of research utilization. While numerous studies exist on professional nurses' use of research in practice, no attempt has been made to systematically evaluate and synthesize this body of literature with respect to the extent to which nurses use research in their clinical practice. The objective of this study was to systematically identify and analyze the available evidence related to the extent to which nurses use research findings in practice. Methods This study was a systematic review of published and grey literature. The search strategy included 13 online bibliographic databases: Cochrane Database of Systematic Reviews, Cochrane Central Register of Controlled Trials, MEDLINE, CINAHL, EMBASE, HAPI, Web of Science, SCOPUS, OCLC Papers First, OCLC WorldCat, ABI Inform, Sociological Abstracts, and Dissertation Abstracts. The inclusion criteria consisted of primary research reports that assess professional nurses' use of research in practice, written in the English or Scandinavian languages. Extent of research use was determined by assigning research use scores reported in each article to one of four quartiles: low, moderate-low, moderate-high, or high. Results Following removal of duplicate citations, a total of 12,418 titles were identified through database searches, of which 133 articles were retrieved. Of the articles retrieved, 55 satisfied the inclusion criteria. The 55 final reports included cross-sectional/survey (n = 51 and quasi-experimental (n = 4 designs. A sensitivity analysis, comparing findings from all reports with those rated moderate (moderate-weak and moderate-strong and strong quality, did not show significant differences. In a majority of the articles identified (n = 38, 69%, nurses reported moderate-high research use. Conclusions According to this review, nurses' reported use of research is moderate-high and has remained

    The AdVAntage Arm is an above-elbow (AE) body-powered arm designed to improve upon, and overcome, some of the major limitations of conventional prostheses. It is the result of research and development (R&D) accomplished at the Center for Engineering Design (CED), University of Utah and Sarcos Research Corporation (SRC), Salt Lake City, UT. The AdVAntage Arm was developed to provide the following main features: lightweight, independent elbow and terminal device (TD) control, and a cable recovery system for full TD actuation at any elbow position. The Department of Veterans Affairs (VA) Rehab R&D Service's Technology Transfer Section (TTS), with collaboration from the VA National Prosthetic and Sensory Aids Service (PSAS), managed a multi-center clinical evaluation of the precommercial AdVAntage Arm (the Arm). The purpose was to objectively assess and affirm the Arm's functional advantages, reliability, clinical application, and commercial readiness. Eleven VA prosthetic services served as evaluation sites with a total of 16 subjects with amputation (14 unilateral and 2 bilateral). Fifteen prosthetists provided their comments. Overall, the results demonstrated that the Arm could be fit for use by persons with transhumeral, and even with forequarter, amputation. Once the learning curve was overcome, the majority of subjects reported that the Arm offered several functional advantages over their conventional prosthesis. Its overall light weight, separation of elbow and TD function, and cable recovery system allowed opening and closure of the TD at any elbow position; resulting in a more fluid manner of use and allowing subjects to perform more activities from waist level and above (especially in the outstretched and overhead positions). At the conclusion of clinical trials, 10 subjects elected to keep the Arm for continued use. The manufacturer is committed to the commercial marketing and technical support of the arm. Based upon the clinical findings, the AdVAntage Arm

    AIM: To evaluate the clinical presentations of solidpseudopapillary tumor of the pancreas (SPT) and examine the diagnosis, treatment, low grade malignant potential of this rare disease.METHODS: We retrospectively reviewed a series of seven patients with SPT managed in our hospital between July 1990 and October 2003. Six females and one male with mean age of 31 years (range 13 to 50 years) were diagnosed with SPT at our institution.RESULTS: Clinical presentation included a palpable abdominal mass in two patients and vague abdominal discomfort in another two. Two patients were asymptomatic;their tumors were found incidentally on abdominal sonographic examination for other reasons. The final patient was admitted with hemoperitoneum secondary to tumor rupture. The mean diameter of the tumors in the seven patients was 10.5 cm (range 5 to 20 cm). The lesions were located in the body and tail in five cases and in the head of the pancreas in two. Surgical procedures included distal pancreatectomy (3), distal pancreatectomy with splenectomy (2), pancreaticoduodenectomy (1) and a pylorus-preserving Whipple procedure (1). There were gross adhesions or histological evidence of infiltration to the adjacent pancreas and/or splenic capsule in four cases. None of the patients received adjuvant therapy.The mean follow up was 7 years (range 0.5 to 14 years).One patient developed multiple liver metastases after 14 years of follow up.CONCLUSION: SPT is a rare tumor that behaves less aggressively than other pancreatic tumor. However, in cases with local invasion, long-term follow up is advisable.

A promising approach to treating cocaine dependence may be agonist-replacement therapy, which is already used effectively in the treatment of opioid and tobacco dependence. The replacement approach for cocaine dependence posits that administration of a long-acting stimulant medication should normalize the neurochemical and behavioral perturbations resulting from chronic cocaine use. One potential medication to be substituted for cocaine is methylphenidate (MPH, as this stimulant possesses pharmacobehavioral properties similar to those of cocaine. Aim: To provide a qualitative review addressing the rationale for the use of MPH as a cocaine substitute and its clinical potential in the treatment of cocaine dependence. Methods: We searched MEDLINE for clinical studies using MPH in patients with cocaine abuse/dependence and screened the bibliographies of the articles found for pertinent literature. Results: MPH, like cocaine, increases synaptic dopamine by inhibiting dopamine reuptake. The discriminative properties, reinforcing potential, and subjective effects of MPH and cocaine are almost identical and, importantly, MPH has been found to substitute for cocaine in animals and human volunteers under laboratory conditions. When taken orally in therapeutic doses, its abuse liability, however, appears low, which is especially true for extended-release MPH preparations. Though there are promising data in the literature, mainly from case reports and

    Full Text Available A competent nursing workforce is important for an effective healthcare system. However, concerns on the poor quality of nursing care and poor competencies among nursing students, nurses, and midwives are increasing in Malawi. Anecdotal notes from stakeholders show shortfalls in nursing education. Furthermore, a large gap between theory and practice exists. This study described the role of academic–clinical partnership in strengthening nursing education. A search of ScienceDirect, PubMed, Medline, and PsychINFO on EBCSOhost and Google Scholar was conducted using the following key words: academic–clinical collaboration, academic–clinical partnership, academic practitioner gap, and college hospital partnership or/and nursing. Furthermore, peer reviewed reports on academic–clinical partnership in nursing were included in the search. Thirty-three records from 2002 to 2016 were reviewed. Six themes emerged from the review: mutual and shared goals, evidence-based practice, resource sharing and collaboration, capacity building, partnership elements, and challenges of academic clinical partnership. The review highlighted that academic–practice partnerships promote shared goal development for the healthcare system. The gap between theory and practice is reduced by the sharing of expertise and by increasing evidence-based practice. Academic clinical partnership improves competencies among students and the safety and health outcomes of patients. The study concluded that the nursing education implemented within an academic clinical partnership becomes relevant to the needs and demands of the healthcare system.

    Free-living amoebae are widely distributed in soil and water. Small number of them was implicated in human disease: Acanthamoeba spp., Naegleria fowleri, Balamuthia mandrillaris and Sappinia diploidea. Some of the infections were opportunistic, occurring mainly in immunocompromised hosts (Acanthamoeba and Balamuthia encephalitis) while others are non opportunistic (Acanthamoeba keratitis, Naegleria meningoencephalitis and some cases of Balamuthia encephalitis). Although, the number of infections caused by these amoebae is low, their diagnosis was still difficult to confirm and so there was a higher mortality, particularly, associated with encephalitis. In this review, we present some information about epidemiology, ecology and the types of diseases caused by these pathogens amoebae.

    2011-10-01

    The purpose of this paper was to evaluate the relationship between the thrombosis and secretory duct dilation, lesion size, clinical types, nature (primary or recurrent) and duration of illness in the development of ranula. A total of 229 cases of sublingual gland cysts were treated with surgical resection from Jan. 1990 to Feb. 2010. The patients' data were investigated on histopathological findings, size of ranula, the clinical types, nature of ranula (primary or recurrent) and duration of illness. Sections from the paraffin-embedded blocks were HE-stained. CK expression was immunohistochemically detected. Among 229 cases the incidence of venous thrombosis was 58.52%. The incidence of venous thrombosis with or without duct dilation was 73.25% and 26.39% respectively, with a significant difference between the two groups (Pranulas with diameter larger or less than 3 cm was 72.22% and 46.28% (Pranula, plunging ranula and mixed ranula was 49.37%, 77.19% and 85.71% respectively, with a significant difference found between oral and plunging or mixed ranula (Pranula patients with duration of illness longer or less than 3 months was 69.77% and 51.75% (Pranulas was 51.85% and 64.85%, without a significant difference noted between them (P>0.05). It is concluded that the formation of venous thrombosis was related to the dilation of secretory duct, lesion size, clinical types, duration of lesion but formation of venous thrombosis was not related to the nature (primary or recurrent) of ranulas.

    A patient with antecedent coccidioidal pulmonary cavitary disease who developed an empyema due to Kingella kingae prompted our analysis of the literature regarding this unusual bacterial pathogen. Formerly classified among other genera and considered a nonpathogen, K. kingae has been increasingly recognized as a cause of human infection. While the most commonly diagnosed infections due to this organism are endocarditis and septic arthritis, there have also been isolated reports of bacteremia, diskitis, abscesses, meningitis, and oropharyngeal infections. The treatment of choice is penicillin, to which K. kingae strains are uniformly susceptible. Recognition of the potential pathogenicity of this microorganism in appropriate clinical settings will probably result in more prompt and specific therapy.

    Infectious bovine keratoconjunctivitis (IBK) is a painful ocular disease affecting cattle worldwide. The publications documenting this condition focus on what is the accepted cause of IBK--Moraxella bovis. This article draws on experience and recorded data made at the time of the initial examination and follow-up visits. Laboratory culture of ocular swabs was undertaken where appropriate. Diagnosis of IBK is usually based on clinical signs, environment, and history. Misdiagnosis of the organisms involved is a genuine possibility. This article focuses on recent outbreaks of bovine ocular disease in the United Kingdom in three counties over a 12-month period.

    Filicide is a form of family violence in which a child is killed by his or her own parent. Most of the literature on filicide addresses the association of mental illness, motivation, and other risk factors with the perpetration of filicide. However, almost no research has addressed the intellectual functioning of perpetrators. We investigated intellectual functioning in a collection of forensic cases seen by the first author over an eight-year period. Nineteen patients who underwent forensic psychiatric evaluation for filicide from August of 1993 to April of 2001 were studied using retrospective case review methodology. Data were obtained from medical and forensic records, reports of family members, legal documents, and other collateral sources. We found that mental illness is common among perpetrators, supporting other findings in the literature. In addition, we found a high frequency of substance abuse among parents who killed their children. However, we also found a significant frequency of intellectual impairment and argue that this factor may have been overlooked in the history of filicide investigations. Familial psychodynamics of filicide will be reviewed and discussed.

    Only 5th decade ago, chronic lymphocytic leukemia (CLL) was only recognized as disease group of presenting features like peripheral lymphocytosis, organomegaly including of splenomegaly. As understanding of disease biology and molecular diagnostic tools are getting improved gradually, characterization of variation in CLL’s clinical courses was facilitated, resulting in better risk stratification and targeted treatments. Consequently multiple new targeted agents have been used in treatment of CLL, it makes improved clinical outcome. Rituximab containing chemoimmunotherapy (combination of rituximab, fludarabine, and cyclophosphamide) have shown better overall response rate and progression-free survival on fit patients’ group in front-line setting, result in standard first-line therapeutic option for CLL. Furthermore, after introducing that the B-cell receptor is crucial for the evolution and progression of CLL, emerging treatments targeting highly activated surface antigens and oncogenic signaling pathways have been associated with several successes in recent decades. These include new anti-CD 20 monoclonal antibody (obinutuzumab), the bruton tyrosine kinase inhibitor (ibrutinib), the phosphatidylinositol 3-kinase inhibitor (idelalisib), and B-cell CLL/lymphoma 2 inhibitor (ABT-199 and ABT-263). So, we discuss not only general pathophysiology of CLL, but also rapidly advancing treatment strategies that are being studied or approved for treatment of CLL. PMID:27044858

    2006-01-01

    Molar incisor hypomineralization (MIH) describes the clinical picture of hypomineralization of systemic origin affecting one or more first permanent molars (FPMs) that are associated frequently with affected incisors. Etiological associations with systemic conditions or environmental insults during the child's first 3 years have been implicated. The complex care involved in treating affected children must address their behavior and anxiety, aiming to provide a durable restoration under pain-free conditions. The challenges include adequate anaesthesia, suitable cavity design, and choice of restorative materials. Restorations in hypomineralized molars appear to fail frequently; there is little evidence-based literature to facilitate clinical decisions on cavity design and material choice. A 6-step approach to management is described: (1) risk identification; (2) early diagnosis; (3) remineralization and desensitization; (4) prevention of caries and posteruption breakdown; (5) restorations and extractions; and (6) maintenance. The high prevalence of MIH indicates the need for research to clarify etiological factors and improve the durability of restorations in affected teeth. The purpose of this paper was to describe the diagnosis, prevalence, putative etiological factors, and features of hypomineralized enamel in molar incisor hypomineralization and to present a sequential approach to management.

    Systematic reviews are accepted as a robust and less biased means of appraising and synthesizing results from high-quality studies. This report collated and summarized all the systematic review evidence relating to the diagnosis and management of trauma-related coagulopathy and transfusion, thereby covering the widest possible body of literature. We defined 4 key clinical questions: (1) What are the best methods of predicting and diagnosing trauma-related coagulopathy? (2) Which methods of clinical management correct coagulopathy? (3) Which methods of clinical management correct bleeding? and (4) What are the outcomes of transfusion in trauma? Thirty-seven systematic reviews were identified through searches of MEDLINE (1950-July 2010), EMBASE (1980-July 2010), The Cochrane Library (Issue 7, 2010), National Guidelines Clearing House, National Library for Health Guidelines Finder, and UKBTS SRI Transfusion Evidence Library (www.transfusionevidencelibrary.com). The evidence from the systematic review literature was scanty with many gaps, and we were not able to conclusively answer any of our 4 questions. Much more needs to be understood about how coagulopathy and bleeding in trauma are altered by transfusion practices and, most importantly, whether this translates into improved survival. There is a need for randomized controlled trials to answer these questions. The approach described in this report provides a framework for incorporating new evidence.

    Intrusive musical imagery (IMI) consists of involuntarily recalled, short, looping fragments of melodies. Musical obsessions are distressing, impairing forms of IMI that merit investigation in their own right and, more generally, research into these phenomena may broaden our understanding of obsessive-compulsive disorder (OCD), which is phenomenologically and etiologically heterogeneous. We present the first comprehensive review of musical obsessions, based on the largest set of case descriptions ever assembled (N=96). Characteristics of musical obsessions are described and compared with normal IMI, musical hallucinations, and visual obsessional imagery. Assessment, differential diagnosis, comorbidity, etiologic hypotheses, and treatments are described. Musical obsessions may be under-diagnosed because they are not adequately assessed by current measures of OCD. Musical obsessions have been misdiagnosed as psychotic phenomena, which has led to ineffective treatment. Accurate diagnosis is important for appropriate treatment. Musical obsessions may respond to treatments that are not recommended for prototypic OCD symptoms.

    PAPA syndrome (Pyogenic Arthritis, Pyoderma gangrenosum, and Acne) is an autosomal dominant, hereditary auto-inflammatory disease arising from mutations in the PSTPIP1/CD2BP1 gene on chromosome 15q. These mutations produce a hyper-phosphorylated PSTPIP1 protein and alter its participation in activation of the "inflammasome" involved in interleukin-1 (IL-1β) production. Overproduction of IL-1β is a clear molecular feature of PAPA syndrome. Ongoing research is implicating other biochemical pathways that may be relevant to the distinct pyogenic inflammation of the skin and joints characteristic of this disease. This review summarizes the recent and rapidly accumulating knowledge on these molecular aspects of PAPA syndrome and related disorders.

  19. Reporting and methods in clinical prediction research: a systematic review.

    Walter Bouwmeester

    Full Text Available BACKGROUND: We investigated the reporting and methods of prediction studies, focusing on aims, designs, participant selection, outcomes, predictors, statistical power, statistical methods, and predictive performance measures. METHODS AND FINDINGS: We used a full hand search to identify all prediction studies published in 2008 in six high impact general medical journals. We developed a comprehensive item list to systematically score conduct and reporting of the studies, based on recent recommendations for prediction research. Two reviewers independently scored the studies. We retrieved 71 papers for full text review: 51 were predictor finding studies, 14 were prediction model development studies, three addressed an external validation of a previously developed model, and three reported on a model's impact on participant outcome. Study design was unclear in 15% of studies, and a prospective cohort was used in most studies (60%. Descriptions of the participants and definitions of predictor and outcome were generally good. Despite many recommendations against doing so, continuous predictors were often dichotomized (32% of studies. The number of events per predictor as a measure of statistical power could not be determined in 67% of the studies; of the remainder, 53% had fewer than the commonly recommended value of ten events per predictor. Methods for a priori selection of candidate predictors were described in most studies (68%. A substantial number of studies relied on a p-value cut-off of p<0.05 to select predictors in the multivariable analyses (29%. Predictive model performance measures, i.e., calibration and discrimination, were reported in 12% and 27% of studies, respectively. CONCLUSIONS: The majority of prediction studies in high impact journals do not follow current methodological recommendations, limiting their reliability and applicability.

    Full Text Available The review presents the fundamental information on the metabolism of dehydroepiandrosterone (DHEA, its biological role and possibilities of its use for replacement therapy. There were studied species differences in the synthesis of DHEA in the adrenal cortex. It was found that DHEA and DHEA-sulfate are produced only by the adrenal glands of humans and monkeys, including lower monkeys. Their biosynthesis involves the following steps: cholesterol → pregnenolone → 17-hydroxypregnenolone → DHEA. The adrenal glands of other species, including rats and mice do not synthesize DHEA. At the same time, in certain brain structures not only in man and monkey, but also in other animals DHEA and its precursors are synthesized de novo which are denoted as neurosteroids. It was demonstrated that Purkinje cells which play an important role in memory formation and learning are mainly place neurosteroid formation in mammals and other vertebrates. To establish the relationship of age and the level of DHEA and other steroids we studied the dynamics of their levels at different periods of postnatal development of people. Peak concentration DHEA observed in aged 25–30 years. In the interval from 20 to 90 years in humans the level falls approximately for 90 %. Cortisol levels in blood does not vary with age, leading to an imbalance in the ratio of cortisol/DHEA. Proved a major role of DHEA as a source (precursor for the synthesis of biologically active sex steroids – testosterone, estradiol and estrone in peripheral tissues. This review presents the bioavailability of DHEA in various physiological and pathological processes in humans and animals. In animal experiments has shown a higher bioavailability of DHEA in transdermal administration as compared with oral administration as in this case there is no steroid rapid inactivation in the liver during its first passage. According to recent studies there is a pronounced dependence of bioavailability of DHEA

    1996-10-01

    This report contains a review and evaluation of three systems analysis studies performed by LITCO on integrated thermal treatment systems and integrated nonthermal treatment systems for the remediation of mixed low-level waste stored throughout the US Department of Energy weapons complex. The review was performed by an independent team of nine researchers from the Energy and Environmental Research Center, Science Applications International Corporation, the Waste Policy Institute, and Virginia Tech. The three studies reviewed were as follows: Integrated Thermal Treatment System Study, Phase 1 -- issued July 1994; Integrated Thermal Treatment System Study, Phase 2 -- issued February 1996; and Integrated Nonthermal Treatment System Study -- drafted March 1996. The purpose of this review was to (1) determine whether the assumptions of the studies were adequate to produce an unbiased review of both thermal and nonthermal systems, (2) to identify the critical areas of the studies that would benefit from further investigation, and (3) to develop a standard template that could be used in future studies to assure a sound application of systems engineering.

    Instrumented 3D-gait analysis (3D-GA) is an important method used to obtain information that is crucial for establishing the level of functional limitation due to pathology, observing its evolution over time and evaluating rehabilitative intervention effects. However, a typical 3D-GA evaluation produces a vast amount of data, and despite its objectivity, its use is complicated, and the data interpretation is difficult. It is even more difficult to obtain an overview on patient cohorts for a comparison. Moreover, there is a growing awareness of the need for a concise index, specifically, a single measure of the 'quality' of a particular gait pattern. Several gait summary measures, which have been used in conjunction with 3D-GA, have been proposed to objectify clinical impression, quantify the degree of gait deviation from normal, stratify the severity of pathology, document the changes in gait patterns over time and evaluate interventions.

  7. Clinical considerations in restorative dentistry - A narrative review

    Full Text Available The relationship between periodontal health and the restoration of teeth is intimate and inseparable. Human teeth are designed in such a way that the individual tooth contributes significantly to their own support as well as collectively the teeth in the arch. Decay on the proximal surfaces occurs mainly due to the faulty interrelationship between the contact area, marginal ridge, the embrasures and the gingiva. An adequate understanding of the relationship between periodontal tissues and restorative dentistry is paramount to ensure an adequate form, function, aesthetics and comfort of the dentition. For long-term survival of restoration, both functionally and esthetically, certain biological considerations are very critical to preserve the health of the periodontium and thus must be given due importance in clinical practice. While most clinicians are aware of this important relationship, uncertainly remains regarding specific concept such as biologic width and its maintainces.

Clinical consequences of DGP include induction of gastrointestinal (GI symptoms (early satiety, abdominal distension, reflux, stomach spasm, postprandial nausea, vomiting, alteration in drug absorption, and destabilization of glycemic control (due to mismatched postprandial glycemic and insulin peaks. Effective nutritional management not only helps in alleviating the symptoms, but also in facilitating better glycemic control. Although there have been no evidence-based guidelines pertaining to the nutrition care process of the DGP, the current dietary recommendations are based on expert opinions or observational studies. The dietary management of gastroparesis needs to be tailored according to the severity of malnutrition and kind of upper GI symptom by changing the volume, consistency, frequency, fiber, fat, and carbohydrates in the meal. Small frequent meals, using more liquid calories, reducing high fat or high fiber, consuming bezoar forming foods, and adjusting meal carbohydrates based on medications or insulin helps in improving the upper GI symptoms and glycemic control. Enteral nutrition can be an option for patients who fail to stabilize their weight loss, or for those who cannot gain weight with oral feedings, while total parenteral nutrition is rarely necessary for the patient with gastroparesis.Keywords: diabetic gastroparesis, delayed gastric emptying, diabetes mellitus, bezoar, GI symptoms, glycemic control

    Montenegro, M; Bonnet, M

    1989-01-01

    A retrospective study of optic nerve pits in patients referred to our clinic during the last 15 years was conducted. The study included 21 eyes in 19 patients. The optic pit was associated with a serous macular detachment (SMD) in 19 eyes (90%). Various treatments of the SMD were used depending on the time period. Systemic corticosteroids were used in five patients. The SMD did not respond to this treatment. Argon laser photocoagulation was applied to the temporal side of the optic disc in five patients. Intravitreal injection of pure gas was used as an adjunct to photocoagulation treatment in eleven eyes. Pure SF 6 was used in 8 eyes, and C 3 F 8 in 3 eyes. The follow-up after treatment was over 6 months in 10 patients who underwent photocoagulation or the combination of photocoagulation and gas injection. The SMD remained unchanged in two eyes which underwent photocoagulation treatment without gas injection. In the group of patients treated by photocoagulation in association with SF 6 injection, the SMD totally reattached in one eye, decreased in 2 eyes and remained unchanged in 2 eyes. Total resorption of subretinal fluid and permanent retinal reattachment occurred in the 3 eyes treated by intravitreal injection of pure C 3 F 8 as an adjunct to photocoagulation treatment. Further clinical investigations on large series of patients are required to determine whether prolonged retinal tamponade by C 3 F 8 gas in association with photocoagulation treatment is a valuable method in the management of SMD complicating optic nerve pits.

    The history of treatment of intracranial aneurysms dates back to the late 18th century. These early physicians largely based their crude techniques around "wire insertion alone, galvanopuncture (electrothrombosis), and fili-galvanopuncture (wire insertion together with electrothrombosis)," albeit with overwhelmingly unfavorable outcomes. By the end of the 20th century, treatment options progressed to include two highly effective, and safe, procedures: surgical clipping and endovascular coiling. These methods have been found to be effective treatments for a large portion of aneurysms, but there still exists a subset of patients that do not respond well to these therapies. While much progress has been made in stent-assisted coiling including the development of newer stents aimed at keep the coil ball from protruding into the parent vessel, the introduction of flow diverters has characterized a new phase in the endovascular treatment of intracranial aneurysms. This treatment paradigm is rapidly becoming the treatment of choice for large and complex aneurysms internal carotid artery. Intrasaccular flow diverters such as the Woven EndoBridge device (WEB) and Luna device are showing promise in the treatment of wide neck bifurcation aneurysms. Other newer devices including the pCONus Bifurcating Aneurysm Implant and Endovascular Clip Systems (eCLIPs) are showing promise in small clinical and preclinical studies. As technology improves, newer devices with ingenious designs are constantly being introduced into the clinical arena. Most of these devices try to address the limitations of traditional endovascular methods in regard to providing a safe and effective treatment of wide-necked bifurcation aneurysms. Several large prospective studies are underway and once completed, the role of these newer devices will be better defined. It is easy to anticipate that with advances in 3D techniques and printing, a future in which customized devices are designed based on the individual

    Full Text Available Xiaohua Qin, Haihui Huang Institute of Antibiotics, Huashan Hospital, Fudan University, Shanghai, People's Republic of China Abstract: Nemonoxacin is a novel C-8-methoxy nonfluorinated quinolone with remarkably enhanced in vitro activity against a wide variety of clinically relevant pathogens, especially gram-positive bacteria, including multidrug-resistant Streptococcus pneumoniae and methicillin-resistant Staphylococcus aureus. It has a low propensity for selecting resistant pathogens than fluoroquinolones, since bacteria become resistant to nemonoxacin only when three different mutations occur in their quinolone resistance-determining regions. Nemonoxacin shows greater efficacy than most of the widely used fluoroquinolones in the murine model of systemic, pulmonary, or ascending urinary tract infection. Nemonoxacin has a sound PK profile in healthy volunteers. It rapidly reaches maximum concentration Cmax 1–2 hours after oral administration in the fasting state and has a relatively long elimination half-life of more than 10 hours, which is similar to fluoroquinolones. Approximately 60%–75% of the administered dose is excreted in unchanged form via kidneys over 24–72 hours. Phase II and III studies of oral nemonoxacin and Phase II studies of intravenous nemonoxacin have been completed in patients with community-acquired pneumonia (CAP, before which the Phase I studies of oral and intravenous nemonoxacin indicated sound tolerance and safety with healthy volunteers. The published results demonstrate that an oral dose of either 500 mg or 750 mg nemonoxacin once daily for 7 days is as effective and safe as levofloxacin 500 mg once daily for 7 days. Nemonoxacin is well-tolerated in patients with CAP. The most common adverse events of oral administration are observed in the gastrointestinal and nervous system, the incidence of which is similar to levofloxacin treatment.

    Several data-mining models have been embedded in the clinical environment to improve decision making and patient safety. Consequently, it is crucial to survey the principal data-mining strategies currently used in clinical decision making and to determine the disadvantages and advantages of using these strategies in data mining in clinical decision making. A literature review was conducted, which identified 21 relevant articles. The article findings showed that multiple models of data mining were used in clinical decision making. Although data mining is efficient and accurate, the models are limited with respect to disease and condition.

    1985-10-01

    In summary, we have described our method of treating phosgene inhalation injury. We have presented two serious cases in detail which demonstrate that survival was associated with aggressive therapy. Several points should be mentioned. The pulmonary edema and resulting fluid and foam production can be so copious as to overwhelm efforts to place an endotracheal tube. The solution is early intubation by the nearest experienced person at the first hint of edema or pulmonary failure. Adequate support of the patient's blood volume is imperative to avert hypovolemic shock and renal failure. A balloon flotation catheter is desirable to monitor pulmonary wedge pressure and avoid overload. Follow-up pulmonary function studies and chest x-rays are recommended 2-3 months after hospital discharge. We have not yet found a reliable test to determine which cases will progress to pulmonary edema. The LDH appears to be the only consistently elevated sign in more serious cases. Finally, we would like to make a plea for the sharing of information from instances of fatal phosgene injury so that the facts can be studied and applied to future cases.

    The Yucca Mountain Project is one part of the Department of Energy`s Office of Civilian Radioactive Waste Management Program (the Program) which was established by the Nuclear Waste Policy Act of 1982, and as amended in 1987. The Program`s goal is to site the nation`s first geologic repository for the permanent disposal of high-level nuclear waste, in the form of spent fuel rod assemblies, generated by the nuclear power industry and a smaller quantity of Government radioactive waste. The Program, which also encompasses the transportation system and the multipurpose canister system was not the subject of this Report. The subject of this Review was only the Yucca Mountain Project in Nevada. While the Review was directed toward the Yucca Mountain Project rather than the Program as a whole, there are certain elements of the Project which cannot be addressed except through discussion of some Program issues. An example is the Total System Life Cycle Cost addressed in Section 7 of this report. Where Program issues are discussed in this Report, the reader is reminded of the scope limitations of the National Association of Regulatory Utility Commissioners (NARUC) contract to review only the Yucca Mountain Project. The primary scope of the Review was to respond to the specific criteria contained in the NARUC scope of work. In responding to these criteria, the Review Team understood that some interested parties have expressed concern over the requirements of the Nuclear Waste Policy Act relative to the Yucca Mountain Project and the nature of activities currently being carried out by the Department of Energy at the Yucca Mountain Project site. The Review Team has attempted to analyze relevant portions of the Nuclear Waste Policy Act as Amended, but has not conducted a thorough analysis of this legislation that could lead to any specific legal conclusions about all aspects of it.

    2005-06-01

    Full Text Available Abstract Background Parathyroid carcinoma is a rare malignancy, with an incidence of 0.5 to 4% of all cases of primary hyperparathyroidism. Surgery is the only curative treatment. Case presentation We report the case of a 66-year-old man referred for a large suspicious substernal goitre associated with severe hypercalcemia due to hyperparathyroidism. After normalization of serum calcium levels, patient underwent surgery. The voluminous cervicomediastinal firm mass could not be removed through the cervical incision; therefore a cervicothoracic approach was employed. Histopathology revealed a giant parathyroid cancer of 450 grams. A review of the literature was also undertaken to summarize the current treatment approaches for this rare malignancy. Conclusion Parathyroid cancer is usually not recognized either preoperatively or intra-operatively. En bloc resection of the tumour with the adjacent tissue is the treatment of choice and it is very important to avoid the rupture of the capsule during operation. Neither tumour size, nor the lymph node status appears to play a role in prognosis. The management of parathyroid carcinoma is a challenge even for experienced surgeons.

    Sadiya, Amena

    2012-01-01

    Diabetic gastroparesis (DGP), or slow emptying of the stomach, is a well-established complication of diabetes mellitus and is typically considered to occur in individuals with long-standing type 1 and type 2 diabetes mellitus. Clinical consequences of DGP include induction of gastrointestinal (GI) symptoms (early satiety, abdominal distension, reflux, stomach spasm, postprandial nausea, vomiting), alteration in drug absorption, and destabilization of glycemic control (due to mismatched postprandial glycemic and insulin peaks). Effective nutritional management not only helps in alleviating the symptoms, but also in facilitating better glycemic control. Although there have been no evidence-based guidelines pertaining to the nutrition care process of the DGP, the current dietary recommendations are based on expert opinions or observational studies. The dietary management of gastroparesis needs to be tailored according to the severity of malnutrition and kind of upper GI symptom by changing the volume, consistency, frequency, fiber, fat, and carbohydrates in the meal. Small frequent meals, using more liquid calories, reducing high fat or high fiber, consuming bezoar forming foods, and adjusting meal carbohydrates based on medications or insulin helps in improving the upper GI symptoms and glycemic control. Enteral nutrition can be an option for patients who fail to stabilize their weight loss, or for those who cannot gain weight with oral feedings, while total parenteral nutrition is rarely necessary for the patient with gastroparesis.

  10. Use of magnetic therapy in clinical neurology: literature review

    Energy Technology Data Exchange (ETDEWEB)

    Shogam, I.I.; Lenchin, V.N.; Baranovskaya, A.V.

    1985-01-01

    A literature survey is presented on the current status of magnetic therapy in clinical neurology. It is generally accepted that the high susceptibility of the nervous system to the magnetic field is due to a large extent to the automatic component. Furthermore, it has also become clear that glial cells are far more susceptible to magnetic fields than are neurons. Controversy prevails on the question of whether the therapeutic effectiveness of magnetic fields involves a direct mechanism of action or an indirect one via reflex mechanisms. Nevertheless, effectiveness of magnetic therapy has been demonstrated and generally accepted in cases dealing with lagophthalmia, ptosis, various neuralgia, radiculitis, neuritis, vascular and infectious pathology of the brain, and so forth. Basically, the effectiveness of such therapy is strongly dependent on the location and the nature of the pathologic process, as well as on the functional status of the autonomic nervous system. In view of this, effective magnetic therapy is highly dependent on individualization of a given approach. 111 References.

  11. Clinical considerations for increasing occlusal vertical dimension: a review.

    Science.gov (United States)

    Abduo, J; Lyons, K

    2012-03-01

    The purpose of this article is to discuss the clinical considerations related to increasing the occlusal vertical dimension (OVD) when restoring a patient's dentition. Thorough extraoral and intraoral evaluations are mandatory to assess the suitability of increasing OVD. In the literature, multiple techniques have been proposed to quantify OVD loss. However, the techniques lack consistency and reliability, which in turn affects the decision of whether to increase the OVD. Therefore, increasing OVD should be determined on the basis of the dental restorative needs and aesthetic demands. In general, a minimal increase in OVD should be applied, though a 5 mm maximum increase in OVD can be justified to provide adequate occlusal space for the restorative material and to improve anterior teeth aesthetics. The literature reflects the safety of increasing the OVD permanently, and although signs and symptoms may develop, these are usually of an interim nature. Whenever indicated, the increase in OVD should be achieved with fixed restorations rather than a removable appliance, due to the predictable patient adaptation. The exception to this is for patients with TMD, where increasing the OVD should still be achieved using removable appliances to control TMD-associated symptoms before considering any form of irreversible procedure.

    1981-05-01

    Postradiation sarcoma of bone is an uncommon but serious sequela of radiation therapy. Seventy-eight Mayo Clinic patients have been treated for sarcomas arising in irradiated bones. They received their initial radiotherapy for a wide variety of nonneoplastic and neoplastic conditions, both benign and malignant. Thirty-five sarcomas arose in bone that was normal at the time of radiotherapy, and 43 arose in irradiated preexisting osseous lesions. The latent period between radiotherapy and diagnosis of sarcoma averaged 14.3 years. Ninety percent of the postradiation sarcomas were either osteosarcomas or fibrosarcomas; chondrosarcoma, malignant (fibrous) histiocytoma, malignant lymphoma, Ewing's tumor, and metastasizing chondroblastoma also occurred. Prompt radical surgery, when feasible, is usually the treatment of choice for the sarcoma. About 30% of patients with sarcomas of the extremities or craniofacial bones survived 5 years without recurrence; there were no disease-free survivors among patients with tumors of the vertebral column, pelvis, or shoulder girdle. The low risk of sarcoma following radiotherapy for the treatment of cancer should not be a contraindication to its use in these patients; however, radiation therapy for benign bone tumors should be reserved for lesions that are not amenable to surgical treatment. An unusual case is also reported herein in which a fibrosarcoma was discovered in the humerus of a patient who had received radiotherapy 55 years previously for a verified osteosarcoma in the same site.

  13. Neonatal staphylococcal scalded skin syndrome: clinical and outbreak containment review.

    Staphylococcal scalded skin syndrome (SSSS) is a toxin-mediated exfoliating skin condition predominated by desquamation and blistering. Neonatal outbreaks have already been reported; however, our outbreak highlights the potential for SSSS following neonatal health promotion measures such as intra-muscular vitamin K administration and metabolic screening (heel prick) as well as effective case containment measures and the value of staff screening. Between February and June 2007, five confirmed cases of neonatal SSSS were identified in full-term neonates born in an Irish regional maternity hospital. All infants were treated successfully. Analysis of contact and environmental screening was undertaken, including family members and healthcare workers. Molecular typing on isolates was carried out. An outbreak control team (OCT) was assembled and took successful prospective steps to prevent further cases. All five Staphylococcus aureus isolates tested positive for exfoliative toxin A, of which two distinct strains were identified on pulsed-field gel electrophoresis analysis. Two cases followed staphylococcal inoculation during preventive measures such as intra-muscular vitamin K administration and metabolic screening (heel prick). None of the neonatal isolates were methicillin resistant. Of 259 hospital staff (70% of staff) screened, 30% were colonised with S. aureus, and 6% were positive for MRSA carriage. This is the first reported outbreak of neonatal SSSS in Ireland. Effective case containment measures and clinical value of OCT is demonstrated. Results of staff screening underlines the need for vigilance and compliance in hand disinfection strategies in maternity hospitals especially during neonatal screening and preventive procedures.

  14. Schwannoma located in the palate: clinical case and literature review.

    López-Carriches, Carmen; Baca-Pérez-Bryan, Rafael; Montalvo-Montero, Santiago

    2009-09-01

    Schwannoma is a benign tumor that originates from the presence of Schwann cells of the peripheral nerves. They are usually asymptomatic, do not recur, and malignant transformation is rare. The preoperative diagnosis is often difficult, and although computed tomography and magnetic resonance imaging are very helpful, in the majority of cases, the diagnosis can only be made during surgery and by histological study. The immunohistochemistry reveals that the Schwannoma cells test positive for S-100 protein. We describe a clinical case of Schwannoma located in the palate of a 15-year-old patient. It is important to highlight that the Schwannoma is usually found in the head and neck, and rarely in the oral cavity. When it does occur in this area, it is more likely to be found in the tongue. Other locations in the oral cavity include: the floor of the mouth, palate, gingiva, vestibular mucosa, lips and mental nerve area, listed from most common to least common. There has been no sign of recurrence two years after surgery.

  15. Clinical perspective: creating an effective practice peer review process-a primer.

    2017-03-01

    Peer review serves as an important adjunct to other hospital quality and safety programs. Despite its importance, the available literature contains virtually no guidance regarding the structure and function of effective peer review committees. This Clinical Perspective provides a summary of the purposes, structure, and functioning of effective peer review committees. We also discuss important legal considerations that are a necessary component of such processes. This discussion includes useful templates for case selection and review. Proper committee structure, membership, work flow, and leadership as well as close cooperation with the hospital medical executive committee and legal representatives are essential to any effective peer review process. A thoughtful, fair, systematic, and organized approach to creating a peer review process will lead to confidence in the committee by providers, hospital leadership, and patients. If properly constructed, such committees may also assist in monitoring and enforcing compliance with departmental protocols, thus reducing harm and promoting high-quality practice.

    1995-02-01

    In the context of new realities, perceptions, and concerns, it is fitting that the government has undertaken this Science and Technology Review, questioning not only how much to spend but also the justification and the best ways to carry out federally-funded research. We share the government's concern about the lack of economic competitiveness of our industries and agree that government-sponsored research should make a bigger contribution to the nation's global economic position. The CSCI, which represents the clinical investigators/scientists in this country, is grateful for having been given the opportunity to make this "tour d'horizon" of Canadian clinical research. In this brief, we have attempted to articulate the needs for, and the benefits of, basic biomedical research because it is the only type of research which will provide us with final answers. However, it should be more closely articulated with applied research, as well as with epidemiological, evaluative, and operational approaches which have been neglected. This brief has emphasized that CSCI is committed to PUTTING MORE SCIENCE INTO MEDICINE by encouraging a greater flow of discoveries from the laboratory research bench to the bedside and the community. We made the point that there is a crisis in patient-oriented research and a decrease of young physicians opting for research careers. The Royal College of Physicians and Surgeons of Canada and the MRC are responsive to this situation, which may compromise our capacity to discharge our broader mission. The MRC has given itself valid instruments to foster the creation of wealth through special programs such as the NCE, the University/Industry program, and the MRC-PMAC partnership. Some refining is in order, and close scrutiny of outcome is essential. Both the academic community and industry have their share of responsibility for the less-than-optimal transfer of knowledge to the market place. Lack of venture capital is also a serious issue.

    2016-05-01

    Full Text Available This article examines the constitutional status of Constitutional Court’s decisions constitutionally guaranteed as final. This status very critical because it could lead Constitutional Court to the judicial supremacy position. This article argues against this possibility. The status of Constitutional Court’s decisions should be critized on the basis that its finality is prima facie, not absolute. As a solution, this article takes a position called departmentalism which means that court and legislature are not supreme in their authority to interpret the constitution. Artikel ini membahas tentang status konstitusional putusan Mahkamah Konstitusi yang dijamin konstitusi bersifat final. Status tersebut sangat kritikal karena dapat mengarahkan Mahkamah Konstitusi ke posisi supremasi yudisial. Artikel ini berargumen tidak setuju atas kemungkinan tersebut. Oleh karena itu, status putusan Mahkamah Konstitusi perlu dikritisi dengan dasar bahwa finalitasnya tersebut bersifat “prima facie”, tidak absolut. Sebagai solusinya, artikel ini mengambil posisi departementalisme yang memiliki pengertian bahwa pengadilan dan legislator tidak memiliki supremasi atas kewenangan untuk melakukan interpretasi konstitusi.

    This paper reviews technical and clinical impact of the Microsoft Kinect in physical therapy and rehabilitation. It covers the studies on patients with neurological disorders including stroke, Parkinson's, cerebral palsy, and MS as well as the elderly patients. Search results in Pubmed and Google scholar reveal increasing interest in using Kinect in medical application. Relevant papers are reviewed and divided into three groups: (1) papers which evaluated Kinect's accuracy and reliability, (2) papers which used Kinect for a rehabilitation system and provided clinical evaluation involving patients, and (3) papers which proposed a Kinect-based system for rehabilitation but fell short of providing clinical validation. At last, to serve as technical comparison to help future rehabilitation design other sensors similar to Kinect are reviewed.

    2016-01-01

    Background: The goal of teleconsultation is to omit geographical and functional distance between two or more geographically separated health care providers. The purpose of present study is to review and analyze physician-physician teleconsultations. Method: The PubMed electronic database was searched. The primary search was done on January 2015 and was updated on December 2015. A fetch and tag plan was designed by the researchers using an online Zotero library. Results: 174 full-text articles of 1702 records met inclusion criteria. Teleconsultation for pediatric patients accounts for 14.36 percent of accepted articles. Surgery and general medicine were the most prevalent medical fields in the adults and pediatrics, respectively. Most teleconsultations were inland experiences (no=135), and the USA, Italy and Australia were the three top countries in this group. Non-specialists health care providers/centers were the dominant group who requested teleconsultation (no=130). Real time, store and forward, and hybrid technologies were used in 50, 31, and 16.7 percent of articles, respectively. The teleconsultation were reported to result in change in treatment plan, referral or evacuation rate, change in diagnosis, educational effects, and rapid decision making. Use of structured or semi-structured template had been noticed only in a very few articles. Conclusion: The present study focused on the recent ten years of published articles on physician-physician teleconsultations. Our findings showed that although there are positive impacts of teleconsultation as improving patient management, still have gaps that need to be repaired. PMID:27708494

    On the cusp of massive commercialization of nanotechnology-enhanced products and services, the physical and chemical analysis of nanoparticles in human specimens merits immediate attention from the research community as a prerequisite for a confident clinical interpretation of their occurrence in the human organism. In this review, we describe the caveats in current practices of extracting and isolating nanoparticles from clinical samples and show that they do not help truly define the clinical significance of detected exogenous nano-sized objects. Finally, we suggest a systematic way of tackling these demanding scientific tasks. More specifically, a precise and true qualitative evaluation of nanoparticles in human biological samples is still hindered by various technical reasons. Such a procedure is more refined when the nature of the pollutants is known, like in the case of nano-sized wear debris originating from biomedical prostheses. Nevertheless, nearly all available analytical methods provide unknown quantitative accuracy and qualitative precision due to the challenging physical and chemical nature of nanoparticles. Without trustworthy information to describe the nanoparticulate load of clinical samples, it is impossible to accurately assess its pathological impact on isolated cases or allow for relevant epidemiological surveys on large populations. Therefore, we suggest that the many and various specimens stored in hospitals be used for the refinement of methods of exhaustive quantitative and qualitative characterization of prominent nanoparticles in complex human milieu.

    2016-04-01

    This paper explored concepts, definitions and theoretical perspectives evaluating clinical competence during nursing education. The questions were: (i) How is clinical competence evaluated? and (ii) What is evaluated? An integrative review of 19 original research articles from 2009 to 2013 was performed. Results showed that evaluation tools were used in 14, observations in 2 and reflecting writing in 3 studies. The students participated in all but one evaluation alone or together with peers, faculty members or preceptors. Three themes were found: (i) professional practice with a caring perspective; (ii) clinical skills and reflective practice; and (iii) cognitive, affective and psychomotor skills both with a nursing perspective. This review shows an emphasis on structured methods with a risk reducing nursing to tasks and skills why combinations with qualitative evaluations are recommended. A holistic view of competence dominated and in designing evaluations, explicit perspectives and operationalized definitions of clinical competence became evident.

    Nursing students are required to develop clinical knowledge, skills and attitudes for professional practice. However, objectivity and parity of students' clinical assessments has been questioned. In the last decade, more objective techniques have been developed, with increased use of Objective Structured Clinical Examinations. We reviewed objective clinical assessment measures used in preregistration nursing courses to determine utilization and the validity and reliability of assessment techniques. A systematic search was made of quantitative research publications between 2000 and May 2011, identifying 16 studies that were subsequently reviewed. The validity and reliability of studies varied, with six studies judged as high quality, using various methodologies. This paper describes methods of instrument development and reports on their application in preregistration nursing programs.

    To examine approaches being used to evaluate and improve quality of HIV clinical services we searched the MEDLINE, Cochrane Library collection, EMBASE, Global Health, and Web of Science databases for articles and abstracts focused on evaluating or improving quality of HIV clinical services. We extracted country income level, targeted clinical services, and quality evaluation approaches, data sources, and criteria. Fifty journal articles and 46 meeting abstracts were included. Of the 96 studies reviewed, 65% were programme evaluations, 71% focused on low- and middle-income countries, and 65% focused on antiretroviral therapy services. With regard to quality, 45% used a quality improvement model or programme, 13% set a quality threshold, and 51% examined patient records to evaluate quality. No studies provided a definition for quality HIV care. Quality assurance and improvement of HIV clinical services is increasingly important. This review highlights gaps in knowledge for future research, and may also help countries and programmes develop their HIV care quality improvement frameworks.

    Particle size reduction can be used for enhancing the dissolution of poorly water-soluble drugs in order to enhance bioavailability. In nanosuspensions, the particle size of the drug is reduced to nanometer size. Nanosuspensions after downstream processing into drug products have successfully shown its impact on formulation design, the augmentation of product life cycle, patent life, and therapeutic efficacy. Formulation considerations for the nanosuspension formulation, its processing into a solid form, and aspects of material characterization are discussed. Technology assessments and feasibility of upstream processes for nanoparticle creation, and subsequently transformation into a drug product via the downstream processes have been reviewed. This paper aims to bridge formulation and process considerations along with patent reviews and may provide further insight into understanding the science and the white space. An analysis of current patent outlook and future trends is described to fully understand the limitations and opportunities in intellectual property generation.

    The purpose of this report was to provide, at BPA's request, a technical review of interim products received for Project 2001-015-00 under contract 6925. BPA sometimes solicits technical reviews for Fish and Wildlife products or issues where outside expertise is required. External review of complex project deliverables assures BPA as a funding agency that the contractor is continuing with scientifically-credible experimental techniques envisioned in the original proposal. If the project's methodology proves feasible, there could be potential applications beyond the project area to similar situations in the Columbia Basin. The Experiment involves artificial flooding during high flow periods and a determination of the portion of the return flows that end up in the Umatilla River during low flow months and within acceptable water quality parameters (e.g., low temperature, few contaminants). Flooding could be a critical water source for aquatic organisms at times of the year when flows in the lower reaches of the Umatilla River are low and water is warmer than would be desired. The experiment was proposed to test whether 'this process, recharges the shallow aquifers of the old flood plain, for natural filtration through the alluvial soils as it returns to the Umatilla River, cleaner and cooler (about 50 degree Fahrenheit) five to six month later (about July and August) substantially cooling the river and [making it] more beneficial to anadromous [fish]'. A substantial amount of preliminary data had been collected and preliminary results were submitted in an interim report 'Echo Meadows Project Winter Artificial Recharge: Final Report for 2001 Baseline (December 2002)'. A substantial amount of addition funding was provided for the last cycle of flooding (Phases II) and final analyses of the full compliment of data collected over the life of the contract (Phase III). Third party scientific review may assist the contractor in producing a

    2016-01-01

    Background The aim of this review is to systematically investigate the effect of a susceptible genotype to periodontitis with the clinical outcomes of periodontal regeneration. Material and Methods Based on a focused question, an electronic search identified 155 unique citations. Three journals (Journal of Periodontology, Journal of Clinical Periodontology and Journal of Periodontal Research), references of relevant studies and review articles were hand-searched. Two independent reviewers implementing eligibility inclusion criteria selected the studies. Results Of the 155, four studies fulfilled the inclusion criteria. All studies were published between 2000 and 2004 and the samples’ size was 40 to 86 patients. Polymorphisms of Interleukin-1 (IL-1) gene were included in all. Three out of four studies failed to identify an association between susceptible genotypes to periodontitis and clinical outcomes of periodontal regeneration, while one found an association. The heterogeneity and small number of studies included prevented the conduct of a meta-analysis. No studies were identified evaluating the effect of other genotypes and as a result only IL-1 genotype studies were included. Conclusions Within the limits of the present review, no direct conclusion for the effect of a susceptible IL-1 genotype status to the clinical outcome after periodontal regeneration could be drawn. The need of more qualitative studies to explore a possible association emerges. Key words:Periodontitis, genotype, periodontal therapy, regeneration, susceptibility, systematic review. PMID:26946210

  13. Review of zolmitriptan and its clinical applications in migraine.

    Science.gov (United States)

    Dowson, Andrew J; Charlesworth, Bruce

    2002-07-01

    Preclinical studies have shown that zolmitriptan is a selective serotonin 5-HT(1B/1D) receptor agonist (triptan). Randomised, placebo-controlled, double-blind trials in patients with migraine have shown that zolmitriptan has good efficacy measured using 2 h response and pain-free rates. Migraine-associated symptoms, including nausea, photophobia and phonophobia, are also improved with zolmitriptan. Oral zolmitriptan (2.5 and 5 mg) has an onset of action within 45 min and efficacy is sustained in most patients who respond at 2 h. The orally-disintegrating zolmitriptan tablet has the advantage that it may be taken immediately, without the need for additional fluids, any time a migraine headache occurs. Patients may benefit in terms of improved efficacy from the convenience of the disintegrating tablet, since there is evidence that taking triptan therapy as early as possible in an attack is advantageous. For similar reasons, as well as improved efficacy, a nasal spray formulation is in development. Zolmitriptan is effective in the treatment of migraine associated with menses and migraine with aura. There is no tachyphylaxis following repeated doses for multiple attacks of migraine over a prolonged period of time. Compared to placebo, the incidence of persistent migraine headache is reduced by zolmitriptan and recurrent migraine headache occurs less frequently. Zolmitriptan has also shown efficacy in the treatment of persistent and/or recurrent migraine headache. Comparative clinical studies have shown overall that zolmitriptan has similar or superior efficacy to sumatriptan in the treatment of migraine. Specifically, zolmitriptan 2.5 mg was significantly more effective than sumatriptan 25 or 50 mg according to a number of end points, including headache response at 2 h. Oral zolmitriptan is also effective in the acute treatment of cluster headache. Zolmitriptan is generally well tolerated, with most adverse events being mild-to-moderate, transient and resolving without

    2009-06-01

    Full Text Available Abstract Neurofibromatosis type 2 (NF2 is a tumour-prone disorder characterised by the development of multiple schwannomas and meningiomas. Prevalence (initially estimated at 1: 200,000 is around 1 in 60,000. Affected individuals inevitably develop schwannomas, typically affecting both vestibular nerves and leading to hearing loss and deafness. The majority of patients present with hearing loss, which is usually unilateral at onset and may be accompanied or preceded by tinnitus. Vestibular schwannomas may also cause dizziness or imbalance as a first symptom. Nausea, vomiting or true vertigo are rare symptoms, except in late-stage disease. The other main tumours are schwannomas of the other cranial, spinal and peripheral nerves; meningiomas both intracranial (including optic nerve meningiomas and intraspinal, and some low-grade central nervous system malignancies (ependymomas. Ophthalmic features are also prominent and include reduced visual acuity and cataract. About 70% of NF2 patients have skin tumours (intracutaneous plaque-like lesions or more deep-seated subcutaneous nodular tumours. Neurofibromatosis type 2 is a dominantly inherited tumour predisposition syndrome caused by mutations in the NF2 gene on chromosome 22. More than 50% of patients represent new mutations and as many as one-third are mosaic for the underlying disease-causing mutation. Although truncating mutations (nonsense and frameshifts are the most frequent germline event and cause the most severe disease, single and multiple exon deletions are common. A strategy for detection of the latter is vital for a sensitive analysis. Diagnosis is based on clinical and neuroimaging studies. Presymptomatic genetic testing is an integral part of the management of NF2 families. Prenatal diagnosis and pre-implantation genetic diagnosis is possible. The main differential diagnosis of NF2 is schwannomatosis. NF2 represents a difficult management problem with most patients facing substantial

    Full Text Available Limited research suggests yoga may be a viable gentle physical activity option with a variety of health-related quality of life, psychosocial and symptom management benefits. The purpose of this review was to determine the clinical significance of patient-reported outcomes from yoga interventions conducted with cancer survivors. A total of 25 published yoga intervention studies for cancer survivors from 2004–2011 had patient-reported outcomes, including quality of life, psychosocial or symptom measures. Thirteen of these studies met the necessary criteria to assess clinical significance. Clinical significance for each of the outcomes of interest was examined based on 1 standard error of the measurement, 0.5 standard deviation, and relative comparative effect sizes and their respective confidence intervals. This review describes in detail these patient-reported outcomes, how they were obtained, their relative clinical significance and implications for both clinical and research settings. Overall, clinically significant changes in patient-reported outcomes suggest that yoga interventions hold promise for improving cancer survivors' well-being. This research overview provides new directions for examining how clinical significance can provide a unique context for describing changes in patient-reported outcomes from yoga interventions. Researchers are encouraged to employ indices of clinical significance in the interpretation and discussion of results from yoga studies.

    Vitamin D deficiency is widespread in Western Countries and has been found related to autoimmune and hematologic disease incidence and clinical course. We evaluated vitamin D levels, vitamin D receptor (VDR) and T helper (Th)1, Th2 and Th17 immunomodulatory cytokines in patients with immune thrombocytopenic purpura (ITP, N=44), primary autoimmune hemolytic anemia (AIHA, n=35), Evans' syndrome (n=5) and chronic idiopathic neutropenia (CIN, n=19) and also tested vitamin D effect on the in vitro production of anti-erythrocyte autoantibodies. 25-OH-vitamin D levels were significantly lower and vitamin D receptor higher in patients than in controls. Among ITP cases, those with very low vitamin D levels displayed reduced platelet counts, irrespective of the bleeding history. In AIHA patients, LDH values negatively correlated with vitamin D levels in mixed forms, and reticulocyte counts were positively related with vitamin D. Considering treatment, AIHA patients who had been treated with 2 therapy lines or more showed lower mean 25-OH-vitamin D levels than those untreated or treated with one line of therapy only. IL-6, IL-10, IL-17 and IFN-γ levels were higher in patients versus controls, whereas TNF-α was significantly reduced. Finally, vitamin D at concentrations of 10, 20, and 40ng/mL reduced the in vitro production of anti-erythrocyte autoantibodies both in pokeweed-stimulated and unstimulated cultures. In conclusion, vitamin D is reduced in autoimmune cytopenias and correlate with disease severity, supporting its possible protective role against the development of autoimmunity. Literature review showed vitamin D deficiency reports both in onco- and in non onco-hematologic diseases with a relationship with disease severity/activity in myeloid and lymphoid neoplasms, as well as in sickle cell disease. Supplementation has produced weak results in autoimmune and hematologic diseases, and further studies are needed.

    Full Text Available ABSTRACT Oral infections are caused by an imbalance in the patient’s indigenous flora which changes from commensal to opportunistic. Odontogenic infections are the most common reason for consultation in children and adolescents. Rational use of antibiotics is the best strategy to avoid microbial resistance. Dental infections should first receive proper local treatment, which can also be complemented with a systemic method. Appropriate drug selection and dosing should be made. Amoxicilin is the first choice for antimicrobial agents in pediatric dentistry. Clindamycin and clarithromycin are the best alternative for patients with penicillin hypersensibility. In this literature review, the authors intended to establish clear clinical management guidelines for emergency treatment and subsequent final resolution. RESUMEN Las infecciones bucales son producidas por un desequilibrio de la flora indígena del paciente que pasa de comensal a oportunista. Las consultas más frecuentes en niños y adolescentes son las infecciones odontogénicas. El uso racional de antibióticos, es la estrategia más importante para evitar la resistencia microbiana. Las infecciones dentarias deben recibir en primera instancia el tratamiento local correspondiente y a veces complementarse con tratamiento sistémico seleccionando y dosificando adecuadamente el fármaco. El antimicrobiano de primera elección en odontopediatría es la amoxicilina y para pacientes con hipersensibilidad a las penicilinas, se indican claritromicina o clindamicina. Esta revisión de la literatura busca establecer pautas de manejo clínico claras para el tratamiento de urgencia y su posterior resolución definitiva.

    Army industrial sludge may be classified as a hazardous waste when it contains oil and grease, metals, and energetic compounds. Biologic separation/treatment of metals from industrial sludge has been identified as a possible alternative to conventional technologies for treating industrial sludge. Biologic treatment of sludge uses naturally occurring biochemical reactions in which pollutants can be used as resources. The process offers a low-cost, highly efficient alternative to existing sludge treatment methods. This report summarizes a literature review that examined the development and status of biotechnology to separate and treat metals in sludge and wastewater.

    The latest advances in eHealth and mHealth have propitiated the rapidly creation and expansion of mobile applications for health care. One of these types of applications are the clinical decision support systems, which nowadays are being implemented in mobile apps to facilitate the access to health care professionals in their daily clinical decisions. The aim of this paper is twofold. Firstly, to make a review of the current systems available in the literature and in commercial stores. Secondly, to analyze a sample of applications in order to obtain some conclusions and recommendations. Two reviews have been done: a literature review on Scopus, IEEE Xplore, Web of Knowledge and PubMed and a commercial review on Google play and the App Store. Five applications from each review have been selected to develop an in-depth analysis and to obtain more information about the mobile clinical decision support systems. Ninety-two relevant papers and 192 commercial apps were found. Forty-four papers were focused only on mobile clinical decision support systems. One hundred seventy-one apps were available on Google play and 21 on the App Store. The apps are designed for general medicine and 37 different specialties, with some features common in all of them despite of the different medical fields objective. The number of mobile clinical decision support applications and their inclusion in clinical practices has risen in the last years. However, developers must be careful with their interface or the easiness of use, which can impoverish the experience of the users.

    The present study evaluated the impact of final-year clinical practice-based training on veterinary students' perceptions of competence in "Day One" abilities by administering a pre- and post-training self-assessment checklist. This study also investigated the influence of student demographics on their perceptions of satisfaction about their own knowledge and skills and preparedness for practice. Perceptions regarding the usefulness of the checklist as a self-audit tool were also sought. Final year students (N=85) were surveyed on commencement and upon completion of the training using a checklist that had been adapted from the list of essential new-graduate abilities that was developed by the Royal College of Veterinary Surgeons and adopted by the Australasian Veterinary Boards Council. Significant improvements in student perceptions of competence were observed for 38 of the 41 abilities. Students' satisfaction with their knowledge and skill base and their perceptions of preparedness for practice were only weakly correlated with overall perceptions of competence for individual ability items and did not vary significantly with student age, gender, background, intended field and location of work, or with their work experience as veterinary nurses-if any-while studying. Two thirds of students believed that access to the self-assessment checklist on commencement of the training helped them identify areas for improvement before graduation. This article concludes that clinical practice-based training results in considerable improvement in senior veterinary students' perceptions of competence in Day One abilities and that a self-assessment checklist may help students guide their learning. Results from the present study may be useful for veterinary schools as they develop or enhance strategies used for outcomes assessment.

  10. Clinical Case Reporting in the Peer-Reviewed Physical Therapy Literature: Time to Move Toward Functioning.

    2015-12-01

    Physical therapists increasingly are contributing clinical case reports to the health literature, which form the basis for higher quality evidence that has been incorporated into clinical practice guidelines. Yet, few resources exist to assist physical therapists with the basic mechanics and quality standards of producing a clinical case report. This situation is further complicated by the absence of uniform standards for quality in case reporting. The importance of including a concise yet comprehensive description of patient functioning in all physical therapy case reports suggest the potential appropriateness of basing quality guidelines on the World Health Organization's International Classification of Functioning Disability and Health (ICF) model. The purpose of this paper is to assist physical therapists in creating high-quality clinical case reports for the peer-reviewed literature using the ICF model as a guiding framework. Along these lines, current recommendations related to the basic mechanics of writing a successful clinical case report are reviewed, as well and a proposal for uniform clinical case reporting requirements is introduced with the aim to improve the quality and feasibility of clinical case reporting in physical therapy that are informed by the ICF model.

    2015-06-01

    Commonly known as saffron, Crocus sativus L and its active components have shown several useful pharmacological effects such as anticonvulsant, antidepressant, anti-inflammatory, antitumor, radical scavenger effects, learning and memory improving effects, etc. There has been an increasing body of data on saffron use in medical databases within the last 20 years. In the current review, the strengths and weaknesses of some of the clinical trials about different pharmacological effects of saffron will be discussed C. sativus extract has been studied in 8 anti-depressant clinical trials in comparison to placebo or some antidepressant drugs, in which saffron showed effectiveness as an antidepressant drug. Clinical trials on anti-Alzheimer effect of saffron demonstrated that it was more effective than the placebo, and as effective as donepezil. 2 clinical trials on antipruritic and complexion promoter in skin care effects of saffron both confirmed that saffron was more efficient than the placebo. In another clinical trial, it was proved that in addition to the weight loss treatment, saffron could reduce snacking frequency. Clinical trials conducted on women with premenstrual syndrome showed that saffron could reduce suffering symptoms more than the placebo and similar to standard treatments.Furthermore, additional clinical trials on effects of saffron on erection dysfunction, allergies, cardiovascular and immune system as well as its safety, toxicity and human pharmacokinetics are reviewed herein.

    Reviews on circulating biomarkers in breast cancer usually focus on one single biomarker or a selective group of biomarkers. An overview summarizing the discovery and evaluation of all blood-based biomarkers in metastatic breast cancer is lacking. This systematic review aims to identify the available evidence of known blood-based biomarkers in metastatic breast cancer, regarding their clinical utility and state-of-the-art position in the validation process. The initial search yielded 1078 original studies, of which 420 were assessed for eligibility. A total of 320 studies were included in the final synthesis. A Development, Evaluation and Application Chart (DEAC) of all biomarkers was developed. Most studies focus on identifying new biomarkers and search for relations between these biomarkers and traditional molecular characteristics. Biomarkers are usually investigated in only one study (68.8%). Only 9.8% of all biomarkers was investigated in more than five studies. Circulating tumor cells, gene expression within tumor cells and the concentration of secreted proteins are the most frequently investigated biomarkers in liquid biopsies. However, there is a lack of studies focusing on identifying the clinical utility of these biomarkers, by which the additional value still seems to be limited according to the investigated evidence.

    2015-03-01

    Nursing students face a variety of challenges to learning in clinical practice, from the theory-practice gap, to a lack of clinical supervision and the ad hoc nature of learning in clinical environments. Mobile technology is proposed as one way to address these challenges. This article comprehensively summarizes and critically reviews the available literature on mobile technology used in undergraduate clinical nursing education. It identifies the lack of clear definitions and theory in the current body of evidence; the variety of mobile devices and applications used; the benefits of mobile platforms in nursing education; and the complexity of sociotechnical factors, such as the cost, usability, portability, and quality of mobile tools, that affect their use in undergraduate clinical nursing education. Implications for nursing education and practice are outlined, and recommendations for future research are discussed.

    Full Text Available Helicobacter pylori (H. pylori is the causative agent in development of gastroduode-nal diseases, such as chronic atrophic gastritis, peptic ulcers, mucosa associated lym-phoid tissue (MALT lymphoma, and gastric cancer. H. pylori has been associated with inflammation in cardia, showing the fact that infection with this bacterium could also be a risk factor for gastric cardia cancer. Gastric cancer is the fourth most common cancer worldwide. This is the second leading cause of cancer-related deaths, and ap-proximately 700,000 people succumb each year to gastric adenocarcinoma. It has been estimated that 69% of the Iranian population currently harbor H. pylori infection. The prevalence of duodenal ulcer and gastric cancer is high in Iranian populations. However, this has been largely influenced by geographic and/or ethnic origin. Epidemi-ology studies have shown that host, environmental, and bacterial factors determine the outcome of H. pylori infection. The bacterium contains allelic diversity and high genet-ic variability into core- and virulence-genes and that this diversity is geographically and ethnically structured. The genetic diversity within H. pylori is greater than within most other bacteria, and its diversity is more than 50-fold higher than that of human DNA. The maintenance of high diversification makes this bacterium to cope with particular challenges in individual hosts. It has been reported that the recombination contributed to the creation of new genes and gene family. Furthermore, the microevolution in cagA and vacA genes is a common event, leading to a change in the virulence phenotype. These factors contribute to the bacterial survival in acidic conditions in stomach and protect it from host immune system, causing tissue damage and clinical disease. In this review article, we discussed the correlation between H. pylori virulence factors and clin-ical outcomes, microevolution of H. pylori virulence genes in a single host

    CERN. Geneva

    2012-01-01

    The CDF Collider Detector at Fermilab ceased data collection on September 30, 2011 after over twenty five years of operation. We review the performance of the CDF Run II data acquisition systems over the last ten of these years while recording nearly 10 fb-1 of proton-antiproton collisions with a high degree of efficiency. Technology choices in the online control and configuration systems and front-end embedded processing have impacted the efficiency and quality of the data accumulated by CDF, and have had to perform over a large range of instantaneous luminosity values and trigger rates. We identify significant sources of problems and successes. In particular, we present our experience computing and acquiring data in a radiation environment, and attempt to correlate system technical faults with radiation dose rate and technology choices.

    Energy Technology Data Exchange (ETDEWEB)

    Columbia River System Operation Review (U.S.)

    1995-11-01

    The Columbia River and its tributaries are the primary water system in the Pacific Northwest, draining some 219,000 square miles in seven states and another 39,500 square miles in British Columbia. Beginning in the 1930`s, the Columbia River has been significantly modified by construction of 30 major dams on the river and its tributaries, along with dozens of non-Federal projects. Construction and subsequent operation of these water development projects have contributed to eight primary uses of the river system, including navigation, flood control, irrigation, electric power generation, fish migration, fish and wildlife habitat, recreation, and water supply and quality considerations. Increasing stress on the water development of the Columbia River and its tributaries has led primary Federal agencies to undertake intensive analysis and evaluation of the operation of these projects. These agencies are the U.S. Army Corps of Engineers and the Bureau of Reclamation, who operate the large Federal dams on the river, and the Bonneville Power Administration who sells the power generated at the dams. This review, termed the System Operation Review (SOR), has as its ultimate goal to define a strategy for future operation of the major Columbia River projects which effectively considers the needs of all river uses. This volume, Appendix D: Cultural resources appendix, Technical imput includes the following: Development of geomorphology based framework for cultural resources management, Dworshak Reservoir, Idaho; Impact profiles for SOR reservoirs; comments from the following Native American tribes: Burns Paiute Tribe; Coville Confederated Tribes; Confederated Tribes of the Warm Springs Indian Reservation; Confederated Tribes and bands of the Yakama Indian Nation (comments); Nez Perce Tribe; Coeur D`Alene Tribe; Spokane Tribe of Indians; The confederated Tribes of the Umatilla Indian Reservation.

    2016-06-01

    Over the past decade, many questions have been raised about graduates' clinical competence and fitness for practice upon completion of their undergraduate education. Despite the significance of this issue, the perspectives of registered nurses have rarely been examined. This systematic review explores the perceptions of experienced registered nurses regarding the clinical competence of new nursing graduates. Original research studies published between 2004-2014 were identified using electronic databases, reference lists, and by searching "grey literature." Papers were critically reviewed and relevant data extracted and synthesized using an approach based on Preferred Reporting Items for Systematic Reviews and Meta-Analysis. From 153 studies initially identified, 15 original research papers were included. Four main research themes were identified: clinical/technical skills, critical thinking, interaction/communication, and overall readiness for practice. Areas of concern in relation to the clinical competence of new nursing graduates specifically related to two themes: critical thinking and clinical/technical skills. Further research is required on strategies identified within the literature with the ultimate aim of ensuring new nursing graduates are safe and competent practitioners.

    Full Text Available American association for cancer education had emphasized the role of structured educational programs for medical students and residents in primary care specialties in order to improve palliative oncology education. Dissatisfaction with the conventional methods of clinical assessment on the part of teachers and students led assessors to search for appropriate alternatives and in 1975, Harden and his colleagues introduced the objective structured clinical examination (OSCE. OSCE was introduced as a standardized tool for objectively assessing clinical competencies−including history-taking, physical examination, communication skills, data interpretation, etc. It consists of a circuit of stations connected in series, with each station devoted to the assessment of a particular competency using pre-determined guidelines or checklists. The Structured Clinical Instruction Module (SCIM modifies the OSCE for teaching purposes. The objective of this review is to provide a focused update on the status and applicability of SCIM and OSCE in cancer for educational use in palliative care. From the 12 studies which were on OSCE and 6 studies which were on SCIM, it appears that the two competency-based evaluation methodologies used in cancer education namely the OSCE and the SCIM are well validated and reliably used across settings and samples of students, practitioners, and patients. Future studies in Indian palliative care settings are warranted prior to extrapolation of existing evidence.

    This systematic review aims to evaluate the therapeutic effects of yoga therapy using an evidence-based approach and investigates the relationship between yoga and the meridian energies based on all available clinical studies in Korea. Sixteen electronic databases will be searched from the inception of the study until January 2016. All clinical evidences that evaluate any type of yoga and any type of control in individuals with any type of condition will be eligible. The methodological quality will be assessed using the Cochrane risk of bias tool for randomized clinical trials and the Newcastle-Ottawa scale for nonrandomized studies. Two authors will independently assess each study for eligibility and the risk of bias, and then they will extract the data. With its extensive, unbiased search of the Korean literature from various databases without any language restrictions, this systematic review will be useful for both practitioners in the field of yoga research as well as for patients.

  20. Intrascrotal extratesticular schwannoma: A clinical case and a review of literature

    Full Text Available Schwannoma is a benign tumor that grows from the Schwann cells forming the myelin sheath of peripheral nerves. The clinical manifestations are nonspecific and generally due to compression of the adjacent structures of a growing tumor. The location of the tumor in the scrotum is rare; its primary diagnosis is difficult and only immunohistochemical examination allows the final diagnosis to be established. The authors present a clinical case of a patient operated on at the Urology Department, Moscow Clinical Research Center, for intrascrotal schwannoma causing impaired microcirculation in the scrotal skin to form purulent scrotal ulcers. In terms of the benign pattern and extratesticular localization of the tumor, its removal without orchifuniculectomy can yield a good clinical result.

    An independent WSRC Operational Readiness Review was performed for the restart of Phase 1 processing in F-Canyon, Building 221-F. Readiness to restart the Second Plutonium Cycle process and solvent recovery was assessed. The ORR was conducted by an ORR board of ten members with the support of a subject matter expert. The chairman and four members were drawn from the Operational Safety Evaluation Department, ESH& QA Division; additional members were drawn from other WSRC divisions, independent of the F-Canyon operating division (NMPD). Based on the results of the readiness verification assessments performed according to the ORR plan and the validation of pre-restart corrective actions, the WSRC independent ORR Board has concluded that the facility has achieved the state of readiness committed to in the Restart Plan. Also, based on the scope of the ORR, it is the opinion of the board that F-Canyon Phase 1 processes can be restarted without undue risk to the safety of the public and onsite workers and without undue risk to the environment.

    Space biology provides an opportunity to study plant physiology and development in a unique microgravity environment. Recent space studies with plants have provided interesting insights into plant biology, including discovering that plants can grow seed-to-seed in microgravity, as well as identifying novel responses to light. However, spaceflight experiments are not without their challenges, including limited space, limited access, and stressors such as lack of convection and cosmic radiation. Therefore, it is important to design experiments in a way to maximize the scientific return from research conducted on orbiting platforms such as the International Space Station. Here, we provide a critical review of recent spaceflight experiments and suggest ways in which future experiments can be designed to improve the value and applicability of the results generated. These potential improvements include: utilizing in-flight controls to delineate microgravity versus other spaceflight effects, increasing scientific return via next-generation sequencing technologies, and utilizing multiple genotypes to ensure results are not unique to one genetic background. Space experiments have given us new insights into plant biology. However, to move forward, special care should be given to maximize science return in understanding both microgravity itself as well as the combinatorial effects of living in space.

  5. Environmental and health effects review for obscurant graphite flakes. Final report, 1991 July--1993 May

    1993-07-01

    The health and environmental effects of obscurant graphite flakes were reviewed and compared to predicted levels of graphite flake material in the field during typical testing and training scenarios. Graphite flake dispersion and deposition for simulated mechanical and pyrotechnic releases were determined using a modified Gaussian atmospheric plume-dispersion model. The potential for wind resuspension of graphite flakes is controlled by weathering processes and incorporation rates in soil. Chemically, graphite flakes pose little risk to aquatic or terrestrial systems. Mechanical damage to plants and invertebrate and vertebrate organisms from the flakes is also minimal. In humans, the pathological and physiological response to inhaled graphite flake is similar to that induced by nuisance dusts and cause only transient pulmonary changes. Repeated exposure to very high concentrations (such as those near the source generator) may overwhelm the clearance mechanisms of the lung and result in pulmonary damage from the retained particles in unprotected individuals. However, these lesions either resolve with time or are of limited severity. Health effects of mixed aerosols of mixed aerosols of graphite and fog oil are similar to those produced by graphite flakes alone. Environmental impacts of fog oil-coated graphite flakes are not well known.

    The Tennessee Valley Authority (TVA) Technology Innovation, Energy Efficiency, Power Delivery and Utilization Office funded and managed a showcase demonstration located in the suburbs of west Knox county, Tennessee. Work started March 2008 with the goal of documenting best practices for retrofitting existing homes and for building new high-efficiency homes. The Oak Ridge National Laboratory and the Electric Power Research Institute (EPRI) provided technical support. An analytical base was developed for helping homeowners, homebuyers, builders, practitioners and the TVA make informed economic decisions for the materials and incentives necessary to build a new high-efficiency home or retrofit an existing home. New approaches to more efficiently control active energy subsystems and information for selecting or upgrading to Energy Star appliances, changing all lights to 100% CFL s and upgrading windows to low-E gas filled glazing yields a 40% energy savings with neutral cash flow for the homeowner. Passive designs were reviewed and recommendations made for envelope construction that is durable and energy efficient. The Campbell Creek project complements the DOE Building Technologies Program strategic goal. Results of the project created technologies and design approaches that will yield affordable energy efficient homes. The 2010 DOE retrofit goals are to find retrofit packages that attain 30% whole house energy savings as documented by pre and post Home Energy rating scores (HERS). Campbell Creek met these goals.

    Columbia River System Operation Review (U.S.)

    1995-11-01

    Currently, the Federal government coordinates the planning and operation of the Federal Columbia River Power System (FCRPS) with projects owned and operated by the region`s non-Federal hydrogenerating utilities pursuant to the Pacific North-west Coordination Agreement (PNCA). The Bureau of Reclamation (Reclamation), the Corps of Engineers (Corps), and the Bonneville Power Administration (BPA) are parties to the PNCA on behalf of the government of the United States. The PNCA is a complex agreement that provides an opportunity for the region`s power producers to maximize the power system`s reliability and economy while meeting their multiple-use objectives. The PNCA does not dictate the operation of the resources it coordinates. It is essentially an accounting mechanism that exchanges the power produced among the parties in order to improve the reliability of the system and reduce regional power costs. Project owners retain complete autonomy to operate as needed to meet their multiple-use requirements. The PNCA was executed in 1964 as an important component of regional plans to maximize the Northwest`s hydro resource capability. Maximization also included the development of storage projects on the Columbia River in Canada pursuant to the terms of the 1964 Columbia River Treaty. Because of the link between power coordination and Treaty issues, the current parties to the PNCA, currently are contemplating entering into a replacement or renewed power coordination agreement. Because the power coordination agreement is a consensual arrangement, its ultimate provisions must be acceptable to all of its signatories. This Appendix R to the Final Environmental Impact Statement of the Columbia River System is a presentation of the Pacific North-west Coordination Agreement.

    Introduction: So far, various models of interdisciplinary collaboration in clinical nursing have been presented, however, yet a comprehensive model is not available. The purpose of this study is to review the evidences that had presented model or framework with qualitative approach about interdisciplinary collaboration in clinical nursing. Methods: All the articles and theses published from 1990 to 10 June 2014 which in both English and Persian models or frameworks of clinicians had presented model or framework of clinical collaboration were searched using databases of Proquest, Scopus, pub Med, Science Direct, and Iranian databases of Sid, Magiran, and Iranmedex. In this review, for published articles and theses, keywords according with MESH such as nurse-physician relations, care team, collaboration, interdisciplinary relations and their Persian equivalents were used. Results: In this study contexts, processes and outcomes of interdisciplinary collaboration as findings were extracted. One of the major components affecting on collaboration that most of the models had emphasized was background of collaboration. Most of studies suggested that the outcome of collaboration were improved care, doctors and nurses’ satisfaction, controlling costs, reducing clinical errors and patient’s safety. Conclusion: Models and frameworks had different structures, backgrounds, and conditions, but the outcomes were similar. Organizational structure, culture and social factors are important aspects of clinical collaboration. So it is necessary to improve the quality and effectiveness of clinical collaboration these factors to be considered. PMID:26153158

  9. A systematic review of the relationship between blood loss and clinical signs.

    Full Text Available INTRODUCTION: This systematic review examines the relationship between blood loss and clinical signs and explores its use to trigger clinical interventions in the management of obstetric haemorrhage. METHODS: A systematic review of the literature was carried out using a comprehensive search strategy to identify studies presenting data on the relationship of clinical signs & symptoms and blood loss. Methodological quality was assessed using the STROBE checklist and the general guidelines of MOOSE. RESULTS: 30 studies were included and five were performed in women with pregnancy-related haemorrhage (other studies were carried in non-obstetric populations. Heart rate (HR, systolic blood pressure (SBP and shock index were the parameters most frequently studied. An association between blood loss and HR changes was observed in 22 out of 24 studies, and between blood loss and SBP was observed in 17 out of 23 studies. An association was found in all papers reporting on the relationship of shock index and blood loss. Seven studies have used Receiver Operating Characteristic Curves to determine the accuracy of clinical signs in predicting blood loss. In those studies the AUC ranged from 0.56 to 0.74 for HR, from 0.56 to 0.79 for SBP and from 0.77 to 0.84 for shock index. In some studies, HR, SBP and shock index were associated with increased mortality. CONCLUSION: We found a substantial variability in the relationship between blood loss and clinical signs, making it difficult to establish specific cut-off points for clinical signs that could be used as triggers for clinical interventions. However, the shock index can be an accurate indicator of compensatory changes in the cardiovascular system due to blood loss. Considering that most of the evidence included in this systematic review is derived from studies in non-obstetric populations, further research on the use of the shock index in obstetric populations is needed.

    The resurgence of the malaria eradication agenda and the increasing number of severe manifestation reports has contributed to a renewed interested in the Plasmodium vivax infection. It is the most geographically widespread parasite causing human malaria, with around 2.85 billion people living under risk of infection. The Brazilian Amazon region reports more than 50% of the malaria cases in Latin America and since 1990 there is a marked predominance of this species, responsible for 85% of cases in 2009. However, only a few complicated cases of P. vivax have been reported from this region. A systematic review of the Brazilian indexed and non-indexed literature on complicated cases of vivax malaria was performed including published articles, masters' dissertations, doctoral theses and national congresses' abstracts. The following information was retrieved: patient characteristics (demographic, presence of co-morbidities and, whenever possible, associated genetic disorders); description of each major clinical manifestation. As a result, 27 articles, 28 abstracts from scientific events' annals and 13 theses/dissertations were found, only after 1987. Most of the reported information was described in small case series and case reports of patients from all the Amazonian states, and also in travellers from Brazilian non-endemic areas. The more relevant clinical complications were anaemia, thrombocytopaenia, jaundice and acute respiratory distress syndrome, present in all age groups, in addition to other more rare clinical pictures. Complications in pregnant women were also reported. Acute and chronic co-morbidities were frequent, however death was occasional. Clinical atypical cases of malaria are more frequent than published in the indexed literature, probably due to a publication bias. In the Brazilian Amazon (considered to be a low to moderate intensity area of transmission), clinical data are in accordance with the recent findings of severity described in diverse P

    2012-08-01

    This paper presents an overview of approaches to analysis of heart sound signals. The paper reviews the milestones in the development of phonocardiogram (PCG) signal analysis. It describes the various stages involved in the analysis of heart sounds and discrete wavelet transform as a preferred method for bio-signal processing. In addition, the gaps that still exist between contemporary methods of signal analysis of heart sounds and their applications for clinical diagnosis is reviewed. A lot of progress has been made but crucial gaps still exist. The findings of this review paper are as follows: there is a lack of consensus in research outputs; inter-patient adaptability of signal processing algorithm is still problematic; the process of clinical validation of analysis techniques was not sufficiently rigorous in most of the reviewed literature; and as such data integrity and measurement are still in doubt, which most of the time led to inaccurate interpretation of results. In addition, the existing diagnostic systems are too complex and expensive. The paper concluded that the ability to correctly acquire, analyse and interpret heart sound signals for improved clinical diagnostic processes has become a priority.

    Full Text Available Abstract Good quality clinical trials are essential to inform the best cystic fibrosis (CF management and care, by determining and comparing the effectiveness of new and existing therapies and drug delivery systems. The formal inclusion of quality of life (QoL as an outcome measure in CF clinical trials is becoming more common. Both an appropriate QoL measure and sound methodology are required in order to draw valid inferences about treatments and QoL. A review was undertaken of randomised controlled trials in cystic fibrosis where QoL was measured. EMBASE, MEDLINE and ISI Web of Science were searched to locate all full papers in the English language reporting randomised controlled trials in cystic fibrosis, published between January 1991 and December 2004. All Cochrane reviews published before December 2004 were hand searched. Papers were included if the authors had reported that they had measured QoL or well being in the trial. 16 trials were identified. The interventions investigated were: antibiotics (4; home versus hospital administration of antibiotics (1; steroids (1; mucolytic therapies (6; exercise (3 and pancreatic enzymes (1. Not one trial evaluated in this review provided conclusive results concerning QoL. This review highlights many of the pitfalls of QoL measurement in CF clinical trials and provides constructive information concerning the design and reporting of trials measuring QoL.

    Predicted workforce shortages have resulted in government initiatives to increase student numbers in preregistration nursing education. In tandem schools of nursing need to ensure students' progress and complete. The aim of this review was to identify factors that influence preregistration nursing students' academic performance, clinical performance and attrition. An integrative review of both quantitative and qualitative literature was conducted using validated appraisal checklists. The review included studies published from 1999 to 2011 in the databases: MEDLINE, CINAHL, Proquest nursing, Proquest Education (via Proquest 5000), ERIC, Journals@Ovid, PsychINFO and ScienceDirect. Studies were categorised according to their impact on academic progression, clinical progression and attrition. Forty four studies were found; most used quantitative methodologies. The review identified that few studies explored factors that impact on students' clinical performance. The four categories that potentially impact on nursing students' academic performance and attrition were: demographic, academic, cognitive and personality/behavioural factors. The challenge for universities committed to students' success is to develop strategies aimed at addressing these factors that are appropriate to specific contexts and student cohorts.

    Major or clinical depression represents a frequent mental illness that is often associated with a high level of morbidity and mortality. Yet, major depression remains under-diagnosed and under-treated. On the level of treatment, it would appear desirable for reasons of better prognosis, to aim more than the simple reduction of depressive symptoms and target their remission resolutely and the fastest return to the individual's optimal functioning. This article presents a systematic review of the literature relating to the clinical impacts of treatment strategies aiming at the improvement of services offered to people who suffer of clinical depression and who consult in primary care. The authors summarize results drawn from 41 studies that include a measurement of the clinical impacts (reduction of symptoms, response, remission and functioning) of various treatment strategies. It appears that using complex treatment strategies favour positive outcomes. The authors propose various paths of research to further increase current knowledge.

    The Ultimaster coronary stent system (Terumo Corporation, Tokyo, Japan) represents a new iteration in drug-eluting stent (DES) technology that has recently received the Conformité Européenne (CE) mark approval for clinical use. The Ultimaster is a thin-strut, cobalt chromium, biodegradable-polymer, sirolimus-eluting coronary stent. The high elasticity of the biodegradable-polymer (PDLLA-PCL) and the abluminal gradient coating technology are additional novel features of this coronary device. The Ultimaster DES has undergone extensive clinical evaluation in two studies: The CENTURY I and II trials. Results from these two landmark studies suggested an excellent efficacy and safety profile of the Ultimaster DES across several lesion and patient subsets, with similar clinical outcomes to contemporary, new-generation DES. The aim of this review is to summarize the rationale behind this novel DES technology and to provide an update of available evidence about the clinical performance of the Ultimaster DES.

    Full Text Available Acromioclavicular joint dislocations are common injuries, which typically occur with trauma in young men. Treatment recommendations for these injuries are highly variable and controversial. There are greater than 100 surgical techniques described for operative treatment of this injury. One of the most widely recommended methods of surgical reconstruction for acromioclavicular joint dislocations is to utilize the coracoacromial ligament for stabilization of the distal clavicle. Several modifications of this procedure have been described which have involved adjunct coracoclavicular fixation or fixation across acromioclavicular joint. Although the literature is replete with descriptive papers, there is paucity of studies evaluating the surgical outcome of this procedure. We systematically reviewed the English language published literature in peer reviewed journals (Medline, EMBASE, SCOPUS and assigned a level of evidence for available studies. We critically reviewed each paper for the flaws and biases and then evaluated the comparable clinical outcomes for various procedures and their modifications. The published literature consists entirely of case series (Level IV evidence with variability in surgical technique and outcome measures. On review there is low level evidence to support the use of coracoacromial ligament for acromioclavicular dislocation but it has been associated with high rate of deformity recurrence. Adjunct fixation does not improve clinical results when compared to isolated coracoacromial ligament transfer. This is in part because of the high incidence of fixation related complications. Similar results are reported with coracoacromial ligament reconstruction for acute and chronic cases. The development of secondary acromioclavicular joint symptoms with distal clavicle retention is poorly reported with the incidence rate varying from 12% to 32%. Despite this, the retention or excision of distal clavicle did not affect overall

    Objective To systematically review the available evidence on paediatric early warning systems (PEWS) for use in acute paediatric healthcare settings for the detection of, and timely response to, clinical deterioration in children. Method The electronic databases PubMed, MEDLINE, CINAHL, EMBASE and Cochrane were searched systematically from inception up to August 2016. Eligible studies had to refer to PEWS, inclusive of rapid response systems and teams. Outcomes had to be specific to the identification of and/or response to clinical deterioration in children (including neonates) in paediatric hospital settings (including emergency departments). 2 review authors independently completed the screening and selection process, the quality appraisal of the retrieved evidence and data extraction; with a third reviewer resolving any discrepancies, as required. Results were narratively synthesised. Results From a total screening of 2742 papers, 90 papers, of varied designs, were identified as eligible for inclusion in the review. Findings revealed that PEWS are extensively used internationally in paediatric inpatient hospital settings. However, robust empirical evidence on which PEWS is most effective was limited. The studies examined did however highlight some evidence of positive directional trends in improving clinical and process-based outcomes for clinically deteriorating children. Favourable outcomes were also identified for enhanced multidisciplinary team work, communication and confidence in recognising, reporting and making decisions about child clinical deterioration. Conclusions Despite many studies reporting on the complexity and multifaceted nature of PEWS, no evidence was sourced which examined PEWS as a complex healthcare intervention. Future research needs to investigate PEWS as a complex multifaceted sociotechnical system that is embedded in a wider safety culture influenced by many organisational and human factors. PEWS should be embraced as a part of a

    Oesophageal cancer (OC) is responsible for the second highest number of cancer-related deaths in South Africa (SA). Squamous cell carcinoma is the most prevalent type with an incidence of 46.7/100,000 and 19.2/100,000 for males and females. This is a systematic review of the clinical diagnosis and management of OC within the South African context. This protocol was registered with the International Prospective Register of Systematic Reviews (PROSPERO) (registration number CRD42016034053) with adherence to PRISMA guidelines. An online search was performed using MEDLINE, EBSCOHost and PubMed. Eligibility criteria for articles included published, original peer-reviewed research addressing clinical management of oesophageal cancer in South Africa. Review articles, case reports, scientific letters and studies published in languages other than English or Afrikaans were excluded. The research terms were 'etiology', 'human', 'esophageal cancer', 'esophageal carcinoma', 'oesophageal cancer', and 'oesophageal carcinoma', 'squamous cell carcinoma', 'Africa' and 'South Africa'. A total of 336 articles were identified. Of these, 146 were immediately excluded and a further 159 were excluded after review. A total of 31 appropriate articles, i.e. 9.2% of searched articles, were included. Thirteen articles addressed chemotherapy and/or radiotherapy, 9 oesophageal luminal therapy, 7 oesophageal surgery and 2 screening. OC research of in SA over the last two decades has mainly been in the form of reviews and opinion papers. Clinical research, auditing and prospectively analysing OC management and outcomes in SA hospitals are sorely needed and should be promoted by both healthcare workers and policy makers alike.

    Full Text Available Aim. The incidence of diabetic osteoporosis (DOP is increasing due to lack of effective management over the past few decades. This review aims to summarize traditional Chinese medicine (TCM suitability in the pathogenesis and clinical and preclinical management of DOP. Methods. Literature sources used were from Medline (Pubmed, CNKI (China Knowledge Resource Integrated Database, and CSTJ (China Science and Technology Journal Database online databases. For the consultation, keywords such as diabetic osteoporosis (DOP, TCM, clinical study, animal experiment, toxicity, and research progress were used in various combinations. Around 100 research papers and reviews were visited. Results. Liver-spleen-kidney insufficiency may result in development of DOP. 18 clinical trials are identified to use TCM compound prescriptions for management of patients with DOP. TCM herbs and their active ingredients are effective in preventing the development of DOP in streptozotocin (STZ and alloxan as well as STZ combined with ovariectomy insulted rats. Among them, most frequently used TCM herbs in clinical trials are Radix Astragali, Radix et Rhizoma Salviae Miltiorrhizae, Radix Rehmanniae Preparata, and Herba Epimedii. Some of TCM herbs also exhibit toxicities in clinical and preclinical research. Conclusions. TCM herbs may act as the novel sources of anti-DOP drugs by improving bone and glucolipid metabolisms. However, the pathogenesis of DOP and the material base of TCM herbs still merit further study.

    Full Text Available Objective: Despite empirical evidence of a relationship between religiosity/spirituality (R/S and mental health and recommendations by professional associations that these research findings be integrated into clinical practice, application of this knowledge in the clinic remains a challenge. This paper reviews the current state of the evidence and provides evidence-based guidelines for spiritual assessment and for integration of R/S into mental health treatment. Methods: PubMed searches of relevant terms yielded 1,109 papers. We selected empirical studies and reviews that addressed assessment of R/S in clinical practice. Results: The most widely acknowledged and agreed-upon application of R/S to clinical practice is the need to take a spiritual history (SH, which may improve patient compliance, satisfaction with care, and health outcomes. We found 25 instruments for SH collection, several of which were validated and of good clinical utility. Conclusions: This paper provides practical guidelines for spiritual assessment and integration thereof into mental health treatment, as well as suggestions for future research on the topic.

    This review aims to examine the literature available to ascertain whether medication errors in clinical practice are the result of nurses' miscalculating drug dosages. The research studies highlighting poor calculation skills of nurses and student nurses have been tested using written drug calculation tests in formal classroom settings [Kapborg, I., 1994. Calculation and administration of drug dosage by Swedish nurses, student nurses and physicians. International Journal for Quality in Health Care 6(4): 389 -395; Hutton, M., 1998.

Nurse Education Today 25, 430-436], but there have been no reviews of the literature on medication errors in practice that specifically look to see whether the medication errors are caused by nurses' poor calculation skills. The databases Medline, CINAHL, British Nursing Index (BNI), Journal of American Medical Association (JAMA) and Archives and Cochrane reviews were searched for research studies or systematic reviews which reported on the incidence or causes of drug errors in clinical practice. In total 33 articles met the criteria for this review. There were no studies that examined nurses' drug calculation errors in practice. As a result studies and systematic reviews that investigated the types and causes of drug errors were examined to establish whether miscalculations by nurses were the causes of errors. The review found insufficient evidence to suggest that medication errors are caused by nurses' poor

    ''Madura foot'' or pedal mycetoma is a rare destructive infection of the skin and subcutaneous tissues of the foot, progressing to involve muscle and bone. The infection can be caused by both bacteria and fungi. Infection typically follows traumatic implantation of bacteria or fungal spores, which are present in soil or on plant material. Clinically, this entity can be difficult to diagnose and can have an indolent and progressive course. Early diagnosis is important to prevent patient morbidity and mortality. We present two cases of pedal mycetoma, review the literature, review new developments in diagnosis, and discuss magnetic resonance imaging (MRI) features of this unusual entity. (orig.)

    2010-01-01

    Infected wounds are still one of the great challenges in medicine. In the last decade, it has become increasingly clear that antimicrobial chemotherapy is limited by the spread of antimicrobial resistance. Fortunately, new, highly effective antiseptic substances with a broad antimicrobial spectrum are available, so local treatment is expected to get increasingly more important in wound therapy. This paper reviews the antiseptic agent polihexanide (polyhexamethylene biguanide, PHMB), one of the most promising substances available today, from a clinical point of view, focusing on efficacy, safety and clinical applications.

    Pulmonary blastoma (PB) is a rare form of lung tumour and is accountable for 0.25-0.5% of primary pulmonary malignancies. Initially pulmonary blastoma was divided into three subtypes: biphasic pulmonary blastoma (BPB) consisting of an epithelial and mesenchymal component, well differentiated fetal adenocarcinoma (WDFA) built of well differentiated epithelium and a mesenchymal component and malignant pleuropulmonary blastoma (PPB). Prognosis in this type of cancer is really poor. We present a current review of literature and a clinical case report. Treatment of PB is very difficult. Data and recommendations about the treatment of pulmonary blastoma are still available therefore we should use only observations and clinical case reports.

  18. Review and evaluation of immobilized algae systems for the production of fuels from microalgae. Final subcontract report

    Energy Technology Data Exchange (ETDEWEB)

    1985-11-01

    The purpose of this paper is to review and evaluate the use of immobilized algae systems. It was the finding that commercial immobilized algae systems are not in operation at this time but, with research, could certainly become so. The use of immobilized algae will depend on, as in all commercial systems, the economic value of the product. This paper reviews the technical feasibility of immobilization as it applies to algae. Finally, the economics of possible immobilized algal systems that would produce liquid fuels were investigated. It was calculated that an immobilized system would have 8.5 times the capital costs of a conventional microalgae culture system. Operational costs would be about equal, although there would be substantial savings of water with the immobilized system. A major problem with immobilizing algae is the fact that sunlight drives the system. At present, an immobilized algal system to mass produce lipids for use as a liquid fuel does not appear to be economically feasible. The major drawback is developing a low-cost system that obtains the same amount of solar energy as provided to a shallow 3 square mile pond while increasing the culture density by an order of magnitude. R and D to increase light availability and to develop low cost transparent tanks could increase the competitiveness of immobilized algal systems. 44 refs., 2 figs., 7 tabs.

    Dengue is a potentially life-threatening illness, and children are at higher risk of severity. This review aimed to systematize the identified clinical and laboratory parameters associated with severe dengue in children, as monitoring these signs and fluid-replacement therapy are actually the cornerstones of dengue treatment. Of the 527 studies initially reviewed, 21 were selected as follows: three cohort studies, three case-control studies, 14 cross-sectional studies and one not defined. Eighteen studies were carried out in Asia and three in the Americas. Hepatomegaly, lethargy, abdominal pain, bleeding, hemoconcentration and thrombocytopenia, all referenced as warning signs in the WHO 2009 Guidelines, were the clinical and laboratory parameters independently associated with severity in more than one study. The recognition of these known warning signs associated to severe dengue disease underlines the usefulness of the WHO 2009 classification.

    2011-09-01

    It has been suggested that yoga has a positive effect on low back pain and function. The objective of this systematic review was to assess the effectiveness of yoga as a treatment option for low back pain. Seven databases were searched from their inception to March 2011. Randomized clinical trials were considered if they investigated yoga in patients with low back pain and if they assessed pain as an outcome measure. The selection of studies, data extraction and validation were performed independently by two reviewers. Seven randomized controlled clinical trials (RCTs) met the inclusion criteria. Their methodological quality ranged between 2 and 4 on the Jadad scale. Five RCTs suggested that yoga leads to a significantly greater reduction in low back pain than usual care, education or conventional therapeutic exercises. Two RCTs showed no between-group differences. It is concluded that yoga has the potential to alleviate low back pain. However, any definitive claims should be treated with caution.

    2011-11-01

    Although there is ongoing debate concerning the clinical status of Internet addiction, and the quality of the extant literature in this emerging field is not optimal, several clinical trials of both pharmacological and psychological treatments for Internet addiction have been published in recent years. A systematic review investigating the reporting quality of eight treatment studies is presented. Reporting quality was defined according to the 2010 Consolidating Standards of Reporting Trials (CONSORT) statement. An evaluation of the reviewed studies highlighted several key limitations, including (a) inconsistencies in the definition and diagnosis of Internet addiction, (b) a lack of randomization and blinding techniques, (c) a lack of adequate controls or other comparison groups, and (d) insufficient information concerning recruitment dates, sample characteristics, and treatment effect sizes. It is concluded that improvements in future studies' design and reporting would be of significant benefit to both researchers and clinicians, and to the overall positioning of Internet addiction in the behavioral addiction field.

    Calendula officinalis extract, C officinalis flower, C officinalis flower extract, C officinalis flower oil, and C officinalis seed oil are cosmetic ingredients derived from C officinalis. These ingredients may contain minerals, carbohydrates, lipids, phenolic acids, flavonoids, tannins, coumarins, sterols and steroids, monoterpenes, sesquiterpenes, triterpenes, tocopherols, quinones, amino acids, and resins. These ingredients were not significantly toxic in single-dose oral studies using animals. The absence of reproductive/developmental toxicity was inferred from repeat-dose studies of coriander oil, with a similar composition. Overall, these ingredients were not genotoxic. They also were not irritating, sensitizing, or photosensitizing in animal or clinical tests but may be mild ocular irritants. The Cosmetic Ingredient Review (CIR) Expert Panel concluded that these ingredients are safe for use in cosmetics in the practices of use and concentration given in this amended safety assessment.

    Walker, Rebekah J; Campbell, Jennifer A; Egede, Leonard E

    2014-09-29

    The purpose of this narrative review was to synthesize the evidence on effective strategies for global health research, training and clinical care in order to identify common structures that have been used to guide program development. A Medline search from 2001 to 2011 produced 951 articles, which were reviewed and categorized. Thirty articles met criteria to be included in this review. Eleven articles discussed recommendations for research, 8 discussed training and 11 discussed clinical care. Global health program development should be completed within the framework of a larger institutional commitment or partnership. Support from leadership in the university or NGO, and an engaged local community are both integral to success and sustainability of efforts. It is also important for program development to engage local partners from the onset, jointly exploring issues and developing goals and objectives. Evaluation is a recommended way to determine if goals are being met, and should include considerations of sustainability, partnership building, and capacity. Global health research programs should consider details regarding the research process, context of research, partnerships, and community relationships. Training for global health should involve mentorship, pre-departure preparation of students, and elements developed to increase impact. Clinical care programs should focus on collaboration, sustainability, meeting local needs, and appropriate process considerations.

    Emiliano Neves Vialle

    Full Text Available ABSTRACT Systematic review of the literature on the evaluation of images of degenerative changes of the spine and its clinical correlation. A systematic literature review was conducted, and the results evaluated for the presence of clinical correlation, as well as the type of imaging method used. The search terms were "Intervertebral Disc Degeneration", "Intervertebral disc", "Classification", "Anulus fibrosus", "Nucleus pulposus", "Lumbar spine", "Degenerative disc disease", "Degeneration", "Zygapophyseal Joint". We also assessed whether there were inter- and intraobserver agreement in the selected works and possible guidelines regarding the treatment and prognosis of patients. Of the 91 reviewed abstracts, 31 articles were selected that met the inclusion criteria. Six articles were related to the cervical spine, 13 to the lumbar spine and 12 were about changes not related specifically to a single segment of the spine. Articles that determined limiting values considered normal were also included, since variations were considered signs of degeneration or pathology. It was not possible to establish the relationship between the changes identified in imaging and the clinical history of patients, either define treatment and prognosis guidelines.

For international confirmatory trials conducted over broad geographic regions and different clinical practice settings, variability in these subjective assessments can be substantial. Centralized endpoint assessment committees (EACs offer a mechanism through which to reduce assessment bias and potentially increase assessment precision and accuracy, particularly in open-label trials. An overview of regulatory agencies' rationales for an EAC is reviewed. In addition, the two main types of EACs, the blinded independent central review, and the consensus panel are compared. Selection of endpoints for EAC evaluation and design of EAC process to maximize EAC value proposition are also discussed.

    AIM To perform a systematic review to grade guidelines and present recommendations for clinical management of non-alcoholic fatty liver disease (NAFLD). METHODS A database search was conducted on PubMed for guidelines published before May 2016, supplemented by reviewing relevant websites. The Appraisal of Guidelines for Research and Evaluation (ARGEE) Instrument II was a tool designed to appraise the methodological rigor and transparency in which a clinical guideline is developed and it is used internationally. It was used to appraise the quality of guidelines in this study. The inclusion criteria include: clinical NAFLD guidelines for adults, published in English, and released by governmental agencies or key organizations. RESULTS Eleven guidelines were included in this study. Since 2007, guidelines have been released in Asia (3 in China, 1 in South Korea, and 1 in Japan), Europe (1 in Italy), America (1 in United States and 1 in Chile) and three international agencies [European associations joint, Asia-Pacific Working Party and World Gastroenterology Organization (WGO)]. Using the ARGEE II instrument, we found US 2012 and Europe 2016 had the highest scores, especially in the areas of rigor of development and applicability. Additionally, Italy 2010 and Korea 2013 also presented comprehensive content, rigorous procedures and good applicability. And WGO 2014 offered various algorithms for clinical practice. Lastly, a practical algorithm for the clinical management was developed, based on the recommended guidelines. CONCLUSION This is the first systematic review of NAFLD guidelines. It may yield insights for physicians and policy-makers in the development and application of guidelines. PMID:27688665

    Sneddon syndrome is defined by the association of livedo racemosa and recurrent cerebrovascular ischemic lesions. The annual incidence is 4/1,000,000. This syndrome particularly affects young women, some reports suggesting a family predisposition. It is a chronic, progressive, arterio-occlusive disease of unknown etiology that involves small and medium-sized arteries. It is usually associated with antiphospholipid antibodies. We report the case of a female patient with Sneddon syndrome with significant family history, personal history of stroke, epilepsy, migraine, cardiovascular involvement, three miscarriages, cognitive decline, noncompliant to therapy, in the absence of antiphospholipid antibodies. This paper aims to analyze the main characteristic features and management of Sneddon syndrome by conducting a literature review related to a clinical case.

    The safety of telemental healthcare delivered to clinically unsupervised settings, such as a personal residence, must be established to inform policy and further the dissemination of telemental health programs. The aim of this article is to provide an overview of safety issues associated with telemental healthcare and, through a systematic literature review, evaluate the safety of telemental healthcare delivered to unsupervised settings. The review resulted in a total of nine studies that specifically evaluated the delivery of telemental healthcare to unsupervised settings. Six of the nine studies reviewed explicitly described safety plans or specific precautions that could be used if necessary. Two of the nine studies reported events that required the researchers to use safety procedures to effectively respond to concerns they had regarding participant safety. In both of these studies, the issues were resolved with prescribed safety procedures. Recommendations and future directions for the development and evaluation of safety protocols are discussed.

    Martin, Paul R

    2016-07-01

    This review begins with a discussion of the nature of stress and then presents the functional model of primary headache as a framework for conceptualizing the complex relationship between stress and headaches. Research is reviewed on stress as a trigger of headaches and how stress can play a role in the developmental and psychosocial context of headaches. Clinical management of headaches from a stress perspective is considered both at the level of trials of behavioral interventions that broadly fit into the stress management category and the additional strategies that might be useful for individual cases based on the research demonstrating associations between stress and headaches. The review concludes by suggesting that although some researchers have questioned whether stress can trigger headaches, overall, the literature is still supportive of such a link. Advances in methodology are discussed, the recent emphasis on protective factors is welcomed, and directions for future research suggested.

    Full Text Available Background. Clinical studies suggest that acupuncture and moxibustion therapy in ulcerative colitis (UC can regulate bowel inflammation, and these treatments have the advantages of low rates of adverse reactions and recurrence as well as good long-term efficacy. We reviewed the current status of clinical studies of the treatment. Methods. Randomized controlled trials (RCTs using the therapy as the major intervention for treating UC were included from 1995 to 2015. The extracted data mainly included diagnostic standards, treatment methods, selection of acupoints, treatment times and courses, and efficacy determination criteria. Results. The use of diagnostic standards and efficacy criteria lacked unification and standardization. There were two main groups: acupuncture and moxibustion therapy combined with drug treatment and the use of all types of acupuncture and moxibustion therapy alone or in combination. The acupoint compositions included distal-proximal point combinations, back-shu point and front-mu point combinations, and acupuncture through meridians. The treatment courses in all the clinical trials had large variations. Conclusion. The treatment of UC in the examined articles was mainly based on the classical theory. However, many links of the clinical regimen design were still lacking, which affected the repeatability of the clinical studies and the accuracy of the clinical conclusions.

    Electroencephalography (EEG) and related methodologies offer the promise of predicting the likelihood that novel therapies and compounds will exhibit clinical efficacy early in preclinical development. These analyses, including quantitative EEG (e.g. brain mapping) and evoked/event-related potentials (EP/ERP), can provide a physiological endpoint that may be used to facilitate drug discovery, optimize lead or candidate compound selection, as well as afford patient stratification and Go/No-Go decisions in clinical trials. Currently, the degree to which these different methodologies hold promise for translatability between preclinical models and the clinic have not been well summarized. To address this need, we review well-established and emerging EEG analytic approaches that are currently being integrated into drug discovery programs throughout preclinical development and clinical research. Furthermore, we present the use of EEG in the drug development process in the context of a number of major central nervous system disorders including Alzheimer's disease, schizophrenia, depression, attention deficit hyperactivity disorder, and pain. Lastly, we discuss the requirements necessary to consider EEG technologies as a biomarker. Many of these analyses show considerable translatability between species and are used to predict clinical efficacy from preclinical data. Nonetheless, the next challenge faced is the selection and validation of EEG endpoints that provide a set of robust and translatable biomarkers bridging preclinical and clinical programs.

    Mental imagery is an under-explored field in clinical psychology research but presents a topic of potential interest and relevance across many clinical disorders, including social phobia, schizophrenia, depression, and post-traumatic stress disorder. There is currently a lack of a guiding framework from which clinicians may select the domains or associated measures most likely to be of appropriate use in mental imagery research. We adopt an interdisciplinary approach and present a review of studies across experimental psychology and clinical psychology in order to highlight the key domains and measures most likely to be of relevance. This includes a consideration of methods for experimentally assessing the generation, maintenance, inspection and transformation of mental images; as well as subjective measures of characteristics such as image vividness and clarity. We present a guiding framework in which we propose that cognitive, subjective and clinical aspects of imagery should be explored in future research. The guiding framework aims to assist researchers in the selection of measures for assessing those aspects of mental imagery that are of most relevance to clinical psychology. We propose that a greater understanding of the role of mental imagery in clinical disorders will help drive forward advances in both theory and treatment.

    Menczer, Joseph

    2009-10-01

    COX-2 is an inducible enzyme expressed only in response to stimuli such as mitogens, cytokines, growth factors or hormones, and is pro-inflammatory. It plays an important role in tumorigenesis. The purpose of the present report is to review the clinical aspects of COX-2 expression in ovarian malignancies. A PubMed (http://www.pubmed.gov/) search of investigations published from July 2001 until August 2008 and containing the term COX-2 in combination with ovarian malignancies was conducted. The clinical aspects of the relevant investigations were reviewed. COX-2 is expressed in ovarian tumors of low malignant potential (LMP), in epithelial ovarian carcinoma (EOC) and primary peritoneal carcinoma (PPC) and apparently plays a role in their carcinogenesis. Its expression seems to be correlated with VEGF that serves as a predictor of poor prognosis in some non-gynecologic malignancies. COX-2 expression is higher in EOC than in LMPs. The results with regard to the association between COX-2 expression and prognostic factors, response to treatment and outcome in ovarian malignancies are inconsistent. Clinical studies dealing with the effect of COX-2 inhibitors on outcome are scarce. The use of COX-2 expression in gynecological malignancies in clinical practice remains to be elucidated.

    2013-01-01

    Clinical research is a specific phase of pharmaceutical industry's production process in which companies test candidate drugs on patients to collect clinical evidence about safety and effectiveness. Information is essential to obtain manufacturing authorization from the national drug agency and, in this way, make profits on the market. Considering this activity, however, the public stakeholder has to face a conflict of interests. On the one side, there is society's necessity to make advances in medicine and, of course, to promote pharmaceutical companies' investments in this specific phase (new generation). On the other side, there is the duty to protect patients involved in these experimental treatments (old generation). To abide by this moral duty, a protection system was developed through the years, based on two legal institutions: informed consent and institutional review board. How should an efficient protection system that would take human experimentation into account be shaped? Would it be possible for the national protection system of patients' rights to affect the choice of whether to develop a clinical trial in a given country or not? Looking at Europe and considering a protection system that is shaped around institutional review boards, this article is an empirical work that tries to give answers to these open questions. It shows how a protection system that can minimize the time necessary to start a trial can positively affect pharmaceutical clinical research, that is, the choice of pharmaceutical companies to start innovative medical treatments in a given country.

    2013-01-01

    Full Text Available Objective. Despite the systematic literature review of the current evidence, we aim to answer the question “ is Deqi an indicator of clinical effects in acupuncture treatment?” Methods. We systematically searched CNKI, VIP, Wanfang Data, PubMed, Embase, and the CENTRAL for three types of study: (1 empirical research probing into the role of Deqi in acupuncture; (2 mechanism studies examining the effect of Deqi on physiological parameters in animal models and human subjects; (3 clinical studies that compared the outcome of acupuncture with Deqi with that of acupuncture without Deqi. Two reviewers independently extracted data, undertook qualitative or quantitative analysis, and summarized findings. Results. The ancient Chinese acupuncturists valued the role of Deqi as a diagnostic tool, a prognosis predictor, and a necessary part of the therapeutic procedure. Findings from modern experimental research provided preliminary evidence for the physiological mechanism that produced Deqi. Few clinical studies generated conflicting evidence of the comparative effectiveness of acupuncture with Deqi versus acupuncture without Deqi for a variety of conditions. Conclusion. The current evidence base is not solid enough to draw any conclusion regarding the predicative value of natural Deqi for clinical efficacy or the therapeutic value of manipulation-facilitated Deqi.

    Although the use of robotic devices to address neuromuscular rehabilitative goals represents a promising technological advance in medical care, the large number of systems being developed and varying levels of clinical study of the devices make it difficult to follow and interpret the results in this new field. This article is a review of the current state-of-the-art in robotic applications in poststroke therapy for the upper extremity, written specifically to help clinicians determine the differences between various systems. We concentrate primarily on systems that have been tested clinically. Robotic systems are grouped by rehabilitation application (e.g., gross motor movement, bilateral training, etc.), and, where possible, the neurorehabilitation strategies employed by each system are described. We close with a discussion of the benefits and concerns of using robotics in rehabilitation and an indication of challenges that must be addressed for therapeutic robots to be applied practically in the clinic.

    Full Text Available The paper describes a 44-year-old male patient with an about 6-year history of hypertrophic pachymeningitis. The major clinical symptoms were characterized by headache, exophthalmos, and blindness in one eye. The data for differential diagnosis of the disease are given. The current literature on the clinical manifestations of hypertrophic pachymeningitis, its differential diagnosis, and the results of magnetic resonance imaging (MRI is reviewed. Diagnostic difficulties at the stage of a clinical observation are due to the nonspecificity of neurological manifestations and the need for a comprehensive examination to detect a somatic disease. MRI can diagnose the disease-specific phenomenon of damage to the meninges, which calls for further careful differentiation. Clinicians must be familiar with alternative differential diagnosis, as a rapid specific therapeutic approach will help avoid long-term or irreversible neurological complications.

    Cancer chemoprevention involves the use of different natural or biologic agents to inhibit or reverse tumor growth. Epidemiological and pre-clinical data suggest that various natural phytochemicals and dietary compounds possess chemopreventive properties, and in-vitro and animal studies support that these compounds may modulate signaling pathways involved in cell proliferation and apoptosis in transformed cells, enhance the host immune system and sensitize malignant cells to cytotoxic agents. Despite promising results from experimental studies, only a limited number of these compounds have been tested in clinical trials and have shown variable results. In this review, we summarize the data regarding select phytochemicals including curcumin, resveratrol, lycopene, folates and tea polyphenols with emphasis on the clinical evidence supporting the efficacy of these compounds in high-risk populations.

    2016-01-01

    Genomics-based non-invasive prenatal screening using cell-free DNA (cfDNA screening) was proposed to reduce the number of invasive procedures in current prenatal diagnosis for fetal aneuploidies. We review here the clinical and ethical issues of cfDNA screening. To date, it is not clear how cfDNA screening is going to impact the performances of clinical prenatal diagnosis and how it could be incorporated in real life. The direct marketing to users may have facilitated the early introduction of cfDNA screening into clinical practice despite limited evidence-based independent research data supporting this rapid shift. There is a need to address the most important ethical, legal, and social issues before its implementation in a mass setting. Its introduction might worsen current tendencies to neglect the reproductive autonomy of pregnant women.

Methods: PubMed and Embase databases were searched until May 21st, 2014. First, duplicate studies were eliminated. Next, study abstracts were read by two readers to assess eligibility. Studies were selected based on predefined inclusion criteria. Of these, data extraction was performed by two readers independently. Results: Of the 987 abstracts that were considered for inclusion, four were eligible for final analysis, which included a total of 572 patients. The diagnostic performance of clinical examination, axillary ultrasound, breast MRI, whole body {sup 18}F-FDG PET-CT, and a prediction model to identify patients with pathological complete response were investigated. Studies were often limited by small sample size. Furthermore, systemic therapy regimens and definitions of clinical and pathological complete response were variable, refraining further pooling of data. The reported positive predictive value of different techniques to identify patients with axillary pathological complete response after neoadjuvant systemic therapy varied between 40% and 100%. Conclusion: At present, there is no accurate noninvasive restaging technique able to identify patients with complete axillary response after neoadjuvant systemic therapy.

    Clinical guidelines have been increasingly used in medicine. They represent a system of recommendations for the conduction of specific procedures used in fields from public health to different diagnostic and therapeutic procedures in clinical medicine. Guidelines are designed to facilitate to medical practitioners the adoption, evaluation and application of an increasing body of evidence and arising number of expert opinions regarding the presently best treatment and to help in delivering proper decision for the management of a patient or condition. Clinical guidelines represent a part of complementary activity by which research is implemented into praxis, standards are defined and clinical excellence is promoted in all health care fields. There are specific conditions which quality guidelines should meet. First of all, they need to be founded on comprehensive literature review, apart from clinical studies and trials in the target field. Also, there are more systems for analyzing and grading the strength of clinical evidence and the level of recommendation emerging from it. Algorithms are used to organize and summarize guidelines. The algorithm itself has a form of an informatic record and a logical flow. Algorithms, especially in case of clinical uncertainty, must be used for the improvement of health care, increasing it's availability and integration of the newest scientific knowledge. They should have an important role in the health care rationalisation, fight against non-rational diagnostics manifested as diagnostic procedures with no clinical indications, it's unnecessary repetition and wrong sequence. Several diagnostic algorithms used in the field of thyroid diseases are presented, since they have been proved to be of great use.

    Full Text Available Questions: Is Kinesio Taping more effective than a sham taping/placebo, no treatment or other interventions in people with musculoskeletal conditions? Is the addition of Kinesio Taping to other interventions more effective than other interventions alone in people with musculoskeletal conditions? Design: Systematic review of randomised trials. Participants: People with musculoskeletal conditions. Intervention: Kinesio Taping was compared with sham taping/placebo, no treatment, exercises, manual therapy and conventional physiotherapy. Outcome measures: Pain intensity, disability, quality of life, return to work, and global impression of recovery. Results: Twelve randomised trials involving 495 participants were included in the review. The effectiveness of the Kinesio Taping was tested in participants with: shoulder pain in two trials; knee pain in three trials; chronic low back pain in two trials; neck pain in three trials; plantar fasciitis in one trial; and multiple musculoskeletal conditions in one trial. The methodological quality of eligible trials was moderate, with a mean of 6.1 points on the 10-point PEDro Scale score. Overall, Kinesio Taping was no better than sham taping/placebo and active comparison groups. In all comparisons where Kinesio Taping was better than an active or a sham control group, the effect sizes were small and probably not clinically significant or the trials were of low quality. Conclusion: This review provides the most updated evidence on the effectiveness of the Kinesio Taping for musculoskeletal conditions. The current evidence does not support the use of this intervention in these clinical populations. PROSPERO registration: CRD42012003436.

    With more vaccines becoming available worldwide, vaccine research is on the rise in developing countries. To gain a better understanding of safety reporting from vaccine clinical research in developing countries, we conducted a systematic review in Medline and Embase (1989-2011) of published randomized clinical trials (RCTs) reporting safety outcomes with ≥50% developing country participation (PROSPERO systematic review registration number: CRD42012002025). Developing country vaccine RCTs were analyzed with respect to the number of participants, age groups studied, inclusion of safety information, number of reported adverse events following immunization (AEFI), type and duration of safety follow-up, use of standardized AEFI case definitions, grading of AEFI severity, and the reporting of levels of diagnostic certainty for AEFI. The systematic search yielded a total number of 50 randomized vaccine clinical trials investigating 12 different vaccines, most commonly rotavirus and malaria vaccines. In these trials, 94,459 AEFI were reported from 446,908 participants receiving 735,920 vaccine doses. All 50 RCTs mentioned safety outcomes with 70% using definitions for at least one AEFI. The most commonly defined AEFI was fever (27), followed by local (16) and systemic reactions (14). Logistic regression analysis revealed a positive correlation between the implementation of a fever case definition and the reporting rate for fever as an AEFI (p=0.027). Overall, 16 different definitions for fever and 7 different definitions for erythema were applied. Predefined AEFI case definitions by the Brighton Collaboration were used in only two out of 50 RCTs. The search was limited to RCTs published in English or German and may be missing studies published locally. The reported systematic review suggests room for improvement with respect to the harmonization of safety reporting from developing country vaccine clinical trials and the implementation of standardized case definitions.

    Full Text Available Context Benign prostatic hyperplasia (BPH that disturbs aged males is described as the abundant, chronic progressive disorder usually associated with lower urinary tract symptoms. The alpha 1A-adrenergic receptor antagonist, tamsulosin (Flomax®/Omnic®, seems to be an appropriate management from the view point of urological surgeons. The current review aimed to evaluate the clinical pharmacological properties of tamsulosin in prostate disorders. Evidence Acquisition United States national library of medicine (PubMed, NLM were searched from April 1991 to March 2016. The Mesh terms were: tamsulosin, tamsulosin pharmacokinetics in urology, tamsulosin in BPH and clinical pharmacokinetics of tamsulosin in BPH. Published clinical trials and review articles applicable to pharmacotherapy of tamsulosin in BPH were reviewed. Results In patients with mild international prostate symptom score (< 8 to moderate symptoms of BPH, initial treatment with an alpha 1-adrenergic antagonist monotherapy were useful. With a half-life of 9 - 13 hours, the oral bioavailability of drug was reported 100%. The drug is metabolized by liver. Excretion through renal was reported 76%. Initial dose of drug was 0.4 mg/day and the maximum dose was reported 0.8 mg/day. The drug could cause dizziness, sever drowsiness and problems in thinking, driving and many other complications. Other serious adverse reactions could be mentioned as hives, rash, itching, and difficulty in breathing, swelling of face, lips, tongue and throat. Tamsulosin therapy should be stopped in patients who experience hypotension. Conclusions To treat BPH therapeutically, it is necessary to stabilize severities of the patient’s symptoms with potential side effects of the treatment. Tamsulosin blocks alpha 1-receptors in smooth muscles both in the bladder neck and prostate, which leads to relaxation and subsequently less resistance to urinary flow. By advancement of tamsulosin, pharmacotherapy strategies could

    The use of titanium implants is well documented and they have high survival and success rates. However, when used as reduced-diameter implants, the risk of fracture is increased. Narrow diameter implants (NDIs) of titanium-zirconium (Ti-Zr) alloy have recently been developed (Roxolid; Institut Straumann AG). Ti-Zr alloys (two highly biocompatible materials) demonstrate higher tensile strength than commercially pure titanium. The aim of this systematic review was to summarize the existing clinical evidence on dental NDIs made from Ti-Zr. A systematic literature search was performed using the Medline database to find relevant articles on clinical studies published in the English language up to December 2014. Nine clinical studies using Ti-Zr implants were identified. Overall, 607 patients received 922 implants. The mean marginal bone loss was 0.36±0.06mm after 1 year and 0.41±0.09mm after 2 years. The follow-up period ranged from 3 to 36 months. Mean survival and success rates were 98.4% and 97.8% at 1 year after implant placement and 97.7% and 97.3% at 2 years. Narrow diameter Ti-Zr dental implants show survival and success rates comparable to regular diameter titanium implants (>95%) in the short term. Long-term follow-up clinical data are needed to confirm the excellent clinical performance of these implants.

    To explore the clinical characteristics, imaging manifestation, diagnosis and treatment for histoplasmosis and to improve therapeutic level, we retrospectively analyzed the clinical data of 8 patients with biopsy-confirmed histoplasmosis from 2004 to 2014 in the Second Xiangya Hospital of Central South University and reviewed relevant literatures. The main clinical symptoms of histoplasmosis included fever, cough, expectoration, chest pain, blood-stained sputum, lymphadenectasis, etc. The major lung imaging features were mass, node or pneumonia-like performance. No case was diagnosed as histoplasimosis firstly. Four patients whose imaging manifestations were focal pulmonary lesion received lobectomy of lung lesions or wedge resection. Clinical and imaging manifestations in 3 patients, who treated with amphotericin B or its liposomal, itraconazole or fluconazole, were improved. The clinical symptoms and imaging findings of histoplasmosis are nonspecific. It is easy for the physicians to misdiagnose histoplasmosis as bacterial infection, lung cancer, tuberculosis lymphoma, etc. Therefore, it is significant and necessary to carry out multiple biopsies combined with multiple etiological examinations for patients with difficult diagnosis.

    Resin-based cements have been frequently employed in clinical practice to lute indirect restorations. However, there are numerous factors that may compromise the clinical performance of those cements. The aim of this literature review is to present and discuss some of the clinical factors that may affect the performance of current resin-based luting systems. Resin cements may have three different curing mechanisms: chemical curing, photo curing or a combination of both. Chemically cured systems are recommended to be used under opaque or thick restorations, due to the reduced access of the light. Photo-cured cements are mainly indicated for translucent veneers, due to the possibility of light transmission through the restoration. Dual-cured are more versatile systems and, theoretically, can be used in either situation, since the presence of both curing mechanisms might guarantee a high degree of conversion (DC) under every condition. However, it has been demonstrated that clinical procedures and characteristics of the materials may have many different implications in the DC of currently available resin cements, affecting their mechanical properties, bond strength to the substrate and the esthetic results of the restoration. Factors such as curing mechanism, choice of adhesive system, indirect restorative material and light-curing device may affect the degree of conversion of the cement and, therefore, have an effect on the clinical performance of resin-based cements. Specific measures are to be taken to ensure a higher DC of the luting system to be used. PMID:26398507

    Clinical trials have shown that natalizumab is highly effective for treating relapsing forms of multiple sclerosis (MS). The purpose of this analysis was to conduct a targeted review of data from country-specific observational studies and registries of natalizumab-treated patients with relapsing MS in order to more fully investigate the longer-term effectiveness and safety of this disease-modifying therapy in real-world clinical practice settings. A PubMed search was conducted on March 13, 2014, using the terms (natalizumab AND multiple sclerosis) AND (observational OR registry OR post-marketing OR clinical practice). Only English-language papers that reported effectiveness (in terms of effects on relapses, disability progression, and magnetic resonance imaging findings) and/or safety results from studies were included. Data from 22 studies/registries were included. Annualized relapse rates decreased by 73%-94% from baseline across the studies, with improvement maintained for up to 5 years during natalizumab treatment. Natalizumab effectiveness was also demonstrated via assessment of disability progression (Expanded Disability Status Scale), radiological measures, and no-evidence-of-disease-activity measures (clinical, radiological, and overall). Results were similar among patient groups stratified by level of disease activity. Safety outcomes were consistent with natalizumab's known safety profile. Data from country-specific observational studies and registries varying in size and scope support the effectiveness and safety of natalizumab in a broad range of patients in clinical practice.

    Full Text Available The aim of this article was to review the role of noninvasive ventilation (NIV in acute pulmonary infectious diseases, such as severe acute respiratory syndrome (SARS, H1N1 and tuberculosis, and to assess the risk of disease transmission with the use of NIV from patients to healthcare workers. We performed a clinical review by searching Medline and EMBASE. These databases were searched for articles on ‘‘clinical trials’’ and ‘‘randomised controlled trials’’. The keywords selected were non-invasive ventilation pulmonary infections, influenza-A (H1N1, SARS and tuberculosis. These terms were cross-referenced with the following keywords: health care workers, airborne infections, complications, intensive care unit and pandemic. The members of the International NIV Network examined the major results regarding NIV applications and SARS, H1N1 and tuberculosis. Cross-referencing mechanical ventilation with SARS yielded 76 studies, of which 10 studies involved the use of NIV and five were ultimately selected for inclusion in this review. Cross-referencing with H1N1 yielded 275 studies, of which 27 involved NIV. Of these, 22 were selected for review. Cross-referencing with tuberculosis yielded 285 studies, of which 15 involved NIV and from these seven were selected. In total 34 studies were selected for this review. NIV, when applied early in selected patients with SARS, H1N1 and acute pulmonary tuberculosis infections, can reverse respiratory failure. There are only a few reports of infectious disease transmission among healthcare workers.

  10. Escitalopram--translating molecular properties into clinical benefit: reviewing the evidence in major depression.

    Leonard, Brian

    2010-08-01

    The majority of currently marketed drugs contain a mixture of enantiomers; however, recent evidence suggests that individual enantiomers can have pharmacological properties that differ importantly from enantiomer mixtures. Escitalopram, the S-enantiomer of citalopram, displays markedly different pharmacological activity to the R-enantiomer. This review aims to evaluate whether these differences confer any significant clinical advantage for escitalopram over either citalopram or other frequently used antidepressants. Searches were conducted using PubMed and EMBASE (up to January 2009). Abstracts of the retrieved studies were reviewed independently by both authors for inclusion. Only those studies relating to depression or major depressive disorder were included. The search identified over 250 citations, of which 21 studies and 18 pooled or meta-analyses studies were deemed suitable for inclusion. These studies reveal that escitalopram has some efficacy advantage over citalopram and paroxetine, but no consistent advantage over other selective serotonin reuptake inhibitors. Escitalopram has at least comparable efficacy to available serotonin-norepinephrine reuptake inhibitors, venlafaxine XR and duloxetine, and may offer some tolerability advantages over these agents. This review suggests that the mechanistic advantages of escitalopram over citalopram translate into clinical efficacy advantages. Escitalopram may have a favourable benefit-risk ratio compared with citalopram and possibly with several other antidepressant agents.

    Full Text Available Arbor vitae (Thuja occidentalis L. is a native European tree widely used in homeopathy and evidence-based phytotherapy. Many reviews and monographs have been published on the herbal substance's description, mode of action and clinical use. However, no comprehensive evidence-based review is available. Therefore, our aim was to search MEDLINE databases and survey manufacturers for further details or unpublished data. This review presents the botany, ethnobotany and phytochemistry, especially the different contents of essential oil (Thujone in relation to different extraction procedures of this medicinal plant. Thuja's antiviral action and immunopharmacological potential, such as stimulatory and co-stimulatory effects on cytokine and antibody production and activation of macrophages and other immunocompetent cells, have been evaluated in numerous in vitro and in vivo investigations. Although no controlled trials have been conducted on Thuja occ alone, many clinical studies have been performed with a herbal medicinal product containing a special extract of Thuja occ and other immunostimulants, demonstrating its therapeutic efficacy and safety in respiratory tract infections.

    Full Text Available To evaluate the current evidence for effectiveness of acupuncture for posttraumatic stress disorder (PTSD in the form of a systematic review, a systematic literature search was conducted in 23 electronic databases. Grey literature was also searched. The key search terms were “acupuncture” and “PTSD.” No language restrictions were imposed. We included all randomized or prospective clinical trials that evaluated acupuncture and its variants against a waitlist, sham acupuncture, conventional therapy control for PTSD, or without control. Four randomized controlled trials (RCTs and 2 uncontrolled clinical trials (UCTs out of 136 articles in total were systematically reviewed. One high-quality RCT reported that acupuncture was superior to waitlist control and therapeutic effects of acupuncture and cognitive-behavioral therapy (CBT were similar based on the effect sizes. One RCT showed no statistical difference between acupuncture and selective serotonin reuptake inhibitors (SSRIs. One RCT reported a favorable effect of acupoint stimulation plus CBT against CBT alone. A meta-analysis of acupuncture plus moxibustion versus SSRI favored acupuncture plus moxibustion in three outcomes. This systematic review and meta-analysis suggest that the evidence of effectiveness of acupuncture for PTSD is encouraging but not cogent. Further qualified trials are needed to confirm whether acupuncture is effective for PTSD.

    The objective structured clinical examination (OSCE) has been used for 10 years at the Ontario Veterinary College, University of Guelph, to evaluate the clinical competencies in ruminant health management of final-year DVM students. The performance of these students in the summative assessment, which includes the use of OSCEs, was compared to their formative assessment, given at the end of the rotation. Specifically, classification of students' performance as poor (bottom 10% of the grade range versus "serious deficits") or superior ("A grade" versus "exceeds expectations") was compared. Agreement between the two types of assessment is slight, regardless of whether assessing diagnostic process skills or technical skills--and regardless of whether all students were assessed or only those enrolled in food-animal or mixed streams in their final year--which suggests that the two assess different types of skills. OSCEs are a useful and viable tool for objectively assessing clinical skills in ruminant health management.

    We report a 14-year-old adolescent girl with selective mutism (SM) and a 7q11.23 microduplication detected by chromosomal microarray (CMA) analysis and reviewed the literature from 18 published clinical reports. Our patient had specific phobias, SM, extreme anxiety, obesity, cutis marmorata, and a round appearing face with a short neck and over folded ears. We reviewed the published clinical, cognitive, behavioral, and cytogenetic findings grouped by speech and language delay, growth and development, craniofacial, clinical, and behavior and cognitive features due to the 7q11.23 microduplication. This microduplication syndrome is characterized by speech delay (91%), social anxiety (42%), attention deficit hyperactivity disorder (ADHD, 37%), autism spectrum disorder (29%), and separation anxiety (13%). Other findings include abnormal brain imaging (80%), congenital heart and vascular defects (54%), and mild intellectual disability (38%). We then compared the phenotype with Williams-Beuren syndrome (WBS) which is due to a deletion of the same chromosome region. Both syndromes have abnormal brain imaging, hypotonia, delayed motor development, joint laxity, mild intellectual disability, ADHD, autism, and poor visuospatial skills but opposite or dissimilar findings regarding speech and behavioral patterns, cardiovascular problems, and social interaction. Those with WBS are prone to have hyperverbal speech, lack of stranger anxiety, and supravalvular aortic stenosis while those with the 7q11.23 microduplication have speech delay, SM, social anxiety, and are prone to aortic dilatation.

    Competencies in Master of Science Clinical Research programs are becoming increasingly common. However, students and programs can only benefit fully from competency-based education if students' competence is formally assessed. Prior to a summative assessment, students must have at least one formative, formal assessment to be sure they are developing competence appropriate for their stage of training. This paper describes the comprehensive competency review (CCR), a milestone for MS students in Clinical Research at the University of Pittsburgh's Institute for Clinical Research Education. The CCR involves metacognitive reflection of the student's learning as a whole, written evidence of each competency, a narrative explaining the choice of evidence for demonstrating competencies, and a meeting in which two faculty members review the evidence and solicit further oral evidence of competence. CCRs allow for individualized feedback at the midpoint in degree programs, providing students with confidence that they will have the means and strategies to develop competence in all areas by the summative assessment of competence at their thesis defense. CCRs have also provided programmatic insight on the need for curricular revisions and additions. These benefits outweigh the time cost on the part of students and faculty in the CCR process.

    The aim of this paper was to systematically review the diagnostic ability of clinical tests to detect lumbar spondylolysis and spondylolisthesis. A systematic literature search of six databases, with no language restrictions, from 1950 to 2014 was concluded on February 1, 2014. Clinical tests were required to be compared against imaging reference standards and report, or allow computation, of common diagnostic values. The systematic search yielded a total of 5164 articles with 57 retained for full-text examination, from which 4 met the full inclusion criteria for the review. Study heterogeneity precluded a meta-analysis of included studies. Fifteen different clinical tests were evaluated for their ability to diagnose lumbar spondylolisthesis and one test for its ability to diagnose lumbar spondylolysis. The one-legged hyperextension test demonstrated low to moderate sensitivity (50%-73%) and low specificity (17%-32%) to diagnose lumbar spondylolysis, while the lumbar spinous process palpation test was the optimal diagnostic test for lumbar spondylolisthesis; returning high specificity (87%-100%) and moderate to high sensitivity (60-88) values. Lumbar spondylolysis and spondylolisthesis are identifiable causes of LBP in athletes. There appears to be utility to lumbar spinous process palpation for the diagnosis of lumbar spondylolisthesis, however the one-legged hyperextension test has virtually no value in diagnosing patients with spondylolysis.

    Traditional factors that once explained men’s sexual difficulties appear insufficient to account for the sharp rise in erectile dysfunction, delayed ejaculation, decreased sexual satisfaction, and diminished libido during partnered sex in men under 40. This review (1) considers data from multiple domains, e.g., clinical, biological (addiction/urology), psychological (sexual conditioning), sociological; and (2) presents a series of clinical reports, all with the aim of proposing a possible direction for future research of this phenomenon. Alterations to the brain's motivational system are explored as a possible etiology underlying pornography-related sexual dysfunctions. This review also considers evidence that Internet pornography’s unique properties (limitless novelty, potential for easy escalation to more extreme material, video format, etc.) may be potent enough to condition sexual arousal to aspects of Internet pornography use that do not readily transition to real-life partners, such that sex with desired partners may not register as meeting expectations and arousal declines. Clinical reports suggest that terminating Internet pornography use is sometimes sufficient to reverse negative effects, underscoring the need for extensive investigation using methodologies that have subjects remove the variable of Internet pornography use. In the interim, a simple diagnostic protocol for assessing patients with porn-induced sexual dysfunction is put forth. PMID:27527226

    The use of a service-oriented architecture (SOA) has been identified as a promising approach for improving health care by facilitating reliable clinical decision support (CDS). A review of the literature through October 2013 identified 44 articles on this topic. The review suggests that SOA related technologies such as Business Process Model and Notation (BPMN) and Service Component Architecture (SCA) have not been generally adopted to impact health IT systems' performance for better care solutions. Additionally, technologies such as Enterprise Service Bus (ESB) and architectural approaches like Service Choreography have not been generally exploited among researchers and developers. Based on the experience of other industries and our observation of the evolution of SOA, we found that the greater use of these approaches have the potential to significantly impact SOA implementations for CDS.
