Pronóstico y tratamiento de la boca seca. Revisión sistemática

No existen protocolos claramente establecidos para el tratamiento de la boca seca. El objetivo de este trabajo es realizar una revisión sistemática de la literatura médica de los últimos 10 años. Hemos utilizado las palabras: «dry mouth», «prognosis», «treatment» y «dentistry». En una primera búsqueda hemos encontrado 1.450 entradas. Con la restricción «clinical trials OR randomized controlled trial OR systemic reviews» se han reducido a 522, de las que 145 eran metaanálisis y revisiones sistemáticas. Se han eliminado las que no eran pertinentes al tema y han quedado reducidas a 53. Posteriormente se descartaron 24 (8 no pertinentes, 7 revisiones y 9 opiniones personales). De los 29 artículos analizados, 15 son ensayos clínicos controlados, 2 ensayos no controlados, 4 estudios observacionales, 2 revisiones sistemáticas y 5 revisiones. Los enfermos mejor estudiados son los pacientes con síndrome de Sjögren y los pacientes irradiados. El tratamiento se centra en el etiológico, preventivo, sintomático, de estimulación salival local y sistémicos. Podemos concluir que el tratamiento debe ser individualizado, pudiéndose aplicar sustitutos salivales y diferentes técnicas de estimulación mecánica. There are no clearly established protocols for the treatment of dry mouth. The aim of this paper is a systematic review of the literature of the past 10 years using the words «dry mouth», «prognosis», «treatment» and «dentistry». The initial search found 1,450 entries and within the restriction «clinical trials OR randomized controlled trial OR systemic reviews» it has been reduced to 522, which 145 were meta-analysis and systematic reviews. Papers not relevant to the issue were removed reducing the entries to 53. Twenty-four were dismissed (8 irrelevant, 7 reviews without adequate information and 9 personal opinions). Of the 29 items tested, 15 were controlled trials, 2 uncontrolled trials, 4 observational studies, 2 systematic reviews and 5 non systematic reviews. The most studied patients were Sjögren's syndrome and the irradiated patients. Treatments are focused on the etiology, prevention, symptomatic, local salivary stimulation and systemic treatments. It can be concluded that treatment must be individualized, salivary substitutes and mechanical stimulation techniques can be applied.

Association entre consommation d'alcool et facteurs de risque cardiovasculaire: une étude sur la population lausannoise. [Association between alcohol consumption and cardiovascular risk factors: a narrative review]

Alors que la consommation modérée d'alcool est liée à un risque plus faible de développer une maladie coronarienne, l'impact d'une consommation plus importante d'alcool sur les facteurs de risque cardiovasculaire (FRCV) et la maladie coronarienne est moins clair. Nous avons étudié l'association entre la consommation d'alcool, les FRCV et l'estimation du risque à dix ans de faire un événement cardiovasculaire dans l'étude populationnelle lausannoise CoLaus. Dans cette étude, 73% des participants consomment de l'alcool, 16% consomment de 14 à 34 unités d'alcool par semaine et 2% consomment 35 unités ou plus par semaine. Cet article montre notamment l'impact d'une consommation importante d'alcool sur les FRCVet passe en revue les liens entre la consommation d'alcool, le type de boissons et les FRCV. [Abstract] Moderate alcohol consumption has been associated with lower coronary heart disease (CHD) risk. However, the impact of higher alcohol consumption on cardiovascular risk factors (CVRFs) is conflicting. We examined the association between alcohol consumption, CVRFs and the estimated 10-year CHD risk in the population-based CoLaus study in Lausanne, Switzerland. Among 5'769 participants without cardiovascular disease, 73% of the participants were alcohol drinkers; 16% consumed 14-34 drinks/week and 2% consumed >= 35 drinks/week. This article shows the impact of high alcohol consumption on CVRFs and reviews the literature on the associations between alcohol consumption and CVRFs.

Acquisitions thérapeutiques en médecine ambulatoire en 2012 [2012 literature findings in ambulatory internal medicine].

In 2012 several articles reported interesting findings for the ambulatory practice in internal general medicine. A negative rapid test for influenza does not rule out that diagnosis. A test assessing the walking speed in the elderly can help determining who would benefit from antihypertensive therapy. Antibiotic treatment has no benefit for acute uncomplicated rhinosinusitis and diverticulitis. Probiotics can reduce the risk of post-antibiotic diarrhea. Daily coffee intake could reduce mortality. Oral supplementation of calcium can be harmful to the cardiovascular system. Subclinical hyperthyroidism should be treated to prevent cardiovascular complications. Aspirin can prevent recurrences in case of a primary thromboembolic event. Local injection of corticosteroids under ultrasonographic guidance for plantar fasciitis can be a safe treatment. Ibuprofen can prevent acute mountain sickness.

EZ-IO intraosseous device implementation in a pre-hospital emergency service : a prospective study and review of the literature

Introduction : La prise en charge des patients critiques nécessite dans la majorité des situations l'obtention rapide d'un accès vasculaire, afin d'administrer des médicaments, des solutés de remplissage, ou des produits sanguins. La mise en place d'un accès vasculaire peut s'avérer difficile chez ces patients. En cas d'échec de pose d'une voie veineuse périphérique, des abords vasculaires alternatifs existent. Il s'agit essentiellement de la pose d'une voie veineuse centrale, la réalisation d'une dénudation veineuse, ou la pose d'une voie intra-osseuse. Depuis le développement de dispositifs d'insertion « semi-automatique » à la fin des années 90, la voie intra-osseuse, traditionnellement réservée aux cas pédiatriques, est de plus en plus fréquemment utilisée chez les patients adultes. Le Service des Urgences du CHUV a introduit en 2009 les dispositifs d'insertion d'aiguilles intra-osseuses de type EZ-IO® (perceuse électrique), en salle de réanimation des urgences vitales (déchoquage), ainsi qu'au sein du secteur préhospitalier pour les interventions du SMUR de Lausanne et de l'hélicoptère REGA de la base de Lausanne. Par cette étude, nous voulions mettre en évidence les aspects épidémiologiques des patients ayant dû être perfusés par cet abord dans un contexte préhospitalier, ainsi que les circonstances cliniques ayant justifié un tel usage, le taux de succès, les éventuelles complications, les médicaments perfusés et la mortalité des patients ayant bénéficié de ce dispositif. Méthode: Chaque patient ayant bénéficié de la mise en place d'une voie intra-osseuse par EZ-IO® du 1er janvier 2009 au 31 décembre 2011 a été inclus. Les données récoltées étaient l'âge, le sexe, l'indication à la mise en place de l'intra-osseuse, la localisation, le taux de succès, les médicaments et fluides administrés, les complications, la mortalité à 48 heures et à la sortie de l'hôpital. Tous les articles mentionnant l'utilisation de ΙΈΖ-ΙΟ® dans des situations cliniques ont également été analysés par une revue de littérature structurée exhaustive, afin de comparer nos résultats avec les données de la littérature. Résultats : Cinquante-huit patients, représentant 60 intra-osseuses EZ-IO®, ont été inclus. Leur âge moyen (47 ans), le taux de succès (90%), les indications, la localisation de l'aiguille (98% au niveau du tibia proximal) et le taux de complications (0%) correspondent aux valeurs trouvées dans la littérature. Le taux de survie de nos patients est de 38% à 48 heures et de 29% à la sortie de l'hôpital. De nombreux médicaments ou solutés de perfusion ont été administrés; l'adrénaline restant le médicament le plus fréquemment administré par cette voie. Dans 7 cas, les patients ont bénéficié d'une induction d'anesthésie par voie intra-osseuse. La revue de littérature a permis de compiler 30 études distinctes, représentant un total de 1603 accès vasculaires de type EZ-IO®. Conclusion : La voie intra-osseuse s'avère fiable et rapide pour obtenir un accès vasculaire, avec un taux de complications très faible et permet l'administration d'un grand nombre de substances. D'autres études sont nécessaires pour évaluer l'impact de la voie intra osseuse, notamment en termes de mortalité, de complications tardives, ainsi que d'analyse coût/bénéfice de ce matériel.

Detecting, quantifying and adjusting for publication bias in meta-analyses: protocol of a systematic review on methods.

BACKGROUND: Health professionals and policymakers aspire to make healthcare decisions based on the entire relevant research evidence. This, however, can rarely be achieved because a considerable amount of research findings are not published, especially in case of 'negative' results - a phenomenon widely recognized as publication bias. Different methods of detecting, quantifying and adjusting for publication bias in meta-analyses have been described in the literature, such as graphical approaches and formal statistical tests to detect publication bias, and statistical approaches to modify effect sizes to adjust a pooled estimate when the presence of publication bias is suspected. An up-to-date systematic review of the existing methods is lacking. METHODS/DESIGN: The objectives of this systematic review are as follows:âeuro¢ To systematically review methodological articles which focus on non-publication of studies and to describe methods of detecting and/or quantifying and/or adjusting for publication bias in meta-analyses.âeuro¢ To appraise strengths and weaknesses of methods, the resources they require, and the conditions under which the method could be used, based on findings of included studies.We will systematically search Web of Science, Medline, and the Cochrane Library for methodological articles that describe at least one method of detecting and/or quantifying and/or adjusting for publication bias in meta-analyses. A dedicated data extraction form is developed and pilot-tested. Working in teams of two, we will independently extract relevant information from each eligible article. As this will be a qualitative systematic review, data reporting will involve a descriptive summary. DISCUSSION: Results are expected to be publicly available in mid 2013. This systematic review together with the results of other systematic reviews of the OPEN project (To Overcome Failure to Publish Negative Findings) will serve as a basis for the development of future policies and guidelines regarding the assessment and handling of publication bias in meta-analyses.

Temporal issues in e-learning research: A literature review

Peer-reviewed

A characteristic EEG pattern in 4p-syndrome: case report and review of the literature.

Deletions on the short arm of chromosome 4 cause Wolf-Hirschhorn syndrome (WHS) and Pitt-Rogers-Danks syndrome (PRDS). WHS is associated with severe growth and mental retardation, microcephaly, a characteristic facies and congenital malformations. The PRDS phenotype is similar to WHS but generally less severe. Seizures occur in the majority of WHS and PRDS patients. Sgrò et al. [17] described a stereotypic electroclinical pattern in four unrelated WHS patients, consisting of intermittent bursts of 2-3 Hz high voltage slow waves with spike wave activity in the parietal areas during drowsiness and sleep associated with myoclonic jerks. We report a patient with PRDS and the typical EEG pattern and review 14 WHS patients with similar EEG findings reported in the literature. CONCLUSION: Awareness and recognition of the characteristic electroclinical findings in Wolf-Hirschhorn syndrome and Pitt-Rogers-Danks syndrome might help in the early diagnosis of such patients.

Oops! Another medication error : a literature review of contributing factors and methods to prevent medication errors

The purpose of this bachelor's thesis was to chart scientific research articles to present contributing factors to medication errors done by nurses in a hospital setting, and introduce methods to prevent medication errors. Additionally, international and Finnish research was combined and findings were reflected in relation to the Finnish health care system. Literature review was conducted out of 23 scientific articles. Data was searched systematically from CINAHL, MEDIC and MEDLINE databases, and also manually. Literature was analysed and the findings combined using inductive content analysis. Findings revealed that both organisational and individual factors contributed to medication errors. High workload, communication breakdowns, unsuitable working environment, distractions and interruptions, and similar medication products were identified as organisational factors. Individual factors included nurses' inability to follow protocol, inadequate knowledge of medications and personal qualities of the nurse. Developing and improving the physical environment, error reporting, and medication management protocols were emphasised as methods to prevent medication errors. Investing to the staff's competence and well-being was also identified as a prevention method. The number of Finnish articles was small, and therefore the applicability of the findings to Finland is difficult to assess. However, the findings seem to fit to the Finnish health care system relatively well. Further research is needed to identify those factors that contribute to medication errors in Finland. This is a necessity for the development of methods to prevent medication errors that fit in to the Finnish health care system.

Cervical nerve root synovial sarcoma in a child with chromosomal (X;18) translocation. Case report and review of the literature.

We report on an 11-year-old female with a history of cervicobrachialgia and progressive weakness of the right arm. Cervical spine MRI showed an enhancing heterogeneous intradural mass occupying the right C6-C7 foramen. She underwent a right C6-C7 foraminotomy with a complete macroscopic removal of the lesion. Pathological examination revealed a synovial sarcoma. Treatment was completed by chemotherapy and proton radiotherapy, and the girl remained free of symptoms for 3 years. After appearance of new symptoms, a local recurrence was confirmed, and despite aggressive treatment with salvage chemotherapy and radiotherapy, the disease progressed beyond medical control, and the child died, 6 years after diagnosis. Early recognition of this rare entity compared to its more benign differential diagnosis is crucial, as an aggressive management is needed.

Uroradiological screening for upper and lower urinary tract anomalies in patients with hypospadias: a systematic literature review.

INTRODUCTION: Hypospadias is associated with anomalies of the urinary tract, but the exact prevalence and significance of these anomalies are still controversial. OBJECTIVES: To assess the percentage of patients with hypospadias and associated urological anomalies, either requiring or not requiring medical or surgical attention. MATERIAL AND METHODS: We searched several databases using the following Mesh terms: hypospadias AND urination, ultrasonography, urinary tract/abnormalities, urinary bladder/radiography, ureteral obstruction, hydronephrosis or vesico-ureteral reflux. Type of uroradiological studies performed, type of urological anomalies, medical or surgical interventions, number of patients available, enrolled and undergoing uroradiological studies and number of patients with abnormal uroradiological exams were recorded. RESULTS: We found 24 studies. Four studies included 100% of available patients. In the other ones, the percentage of patients undergoing uroradiological screening varied from 12 to 82%. Frequency of anomalies varied from 0 to 56%. The most common anomalies were kidney position anomalies, vesico-ureteral reflux and hydronephrosis. CONCLUSIONS: The data published about screening patients with hypospadias for associated anomalies of their urinary tract are of poor quality. The clinical significance of the anomalies found is difficult to evaluate. We found no relationship between the severity of the hypospadias and associated anomalies of the upper or lower urinary tract.

Appropriateness of colonoscopy in Europe (EPAGE II). Screening for colorectal cancer.

BACKGROUND AND STUDY AIMS: To summarize the published literature on assessment of appropriateness of colonoscopy for screening for colorectal cancer (CRC) in asymptomatic individuals without personal history of CRC or polyps, and report appropriateness criteria developed by an expert panel, the 2008 European Panel on the Appropriateness of Gastrointestinal Endoscopy, EPAGE II. METHODS: A systematic search of guidelines, systematic reviews, and primary studies regarding colonoscopy for screening for colorectal cancer was performed. The RAND/UCLA Appropriateness Method was applied to develop appropriateness criteria for colonoscopy in these circumstances. RESULTS: Available evidence for CRC screening comes from small case-controlled studies, with heterogeneous results, and from indirect evidence from randomized controlled trials (RCTs) on fecal occult blood test (FOBT) screening and studies on flexible sigmoidoscopy screening. Most guidelines recommend screening colonoscopy every 10 years starting at age 50 in average-risk individuals. In individuals with a higher risk of CRC due to family history, there is a consensus that it is appropriate to offer screening colonoscopy at < 50 years. EPAGE II considered screening colonoscopy appropriate above 50 years in average-risk individuals. Panelists deemed screening colonoscopy appropriate for younger patients, with shorter surveillance intervals, where family or personal risk of colorectal cancer is higher. A positive FOBT or the discovery of adenomas at sigmoidoscopy are considered appropriate indications. CONCLUSIONS: Despite the lack of evidence based on randomized controlled trials (RCTs), colonoscopy is recommended by most published guidelines and EPAGE II criteria available online (http://www.epage.ch), as a screening option for CRC in individuals at average risk of CRC, and undisputedly as the main screening tool for CRC in individuals at moderate and high risk of CRC.

Injury pattern of the Flash-Ball, a less-lethal weapon used for law enforcement: report of two cases and review of the literature.

Less-lethal weapons are used in law enforcement to neutralize combative individuals and to disperse riot crowds. Local police recently used such an impact weapon, the Flash-Ball, in two different situations. This gun fires large rubber bullets with kinetic energies around 200 J. Although it is designed to avoid skin penetration, impacts at such energies may still create major trauma with associated severe injuries to internal organs. This is a report of 2 patients shot with the Flash-Ball who required medical attention. One could be discharged quickly, but the other required hospitalization for heart and lung contusion. Both patients required advanced investigations including computed tomography (CT) scan. The medical literature on injuries induced by less-lethal impact weapons is reviewed. Impacts from the Flash-Ball can cause significant injury to internal organs, even without penetration. Investigations as for other high-energy blunt traumas are called for in these cases.

Defining publication bias: protocol for a systematic review of highly cited articles and proposal for a new framework.

BACKGROUND: Selective publication of studies, which is commonly called publication bias, is widely recognized. Over the years a new nomenclature for other types of bias related to non-publication or distortion related to the dissemination of research findings has been developed. However, several of these different biases are often still summarized by the term 'publication bias'. METHODS/DESIGN: As part of the OPEN Project (To Overcome failure to Publish nEgative fiNdings) we will conduct a systematic review with the following objectives:- To systematically review highly cited articles that focus on non-publication of studies and to present the various definitions of biases related to the dissemination of research findings contained in the articles identified.- To develop and discuss a new framework on nomenclature of various aspects of distortion in the dissemination process that leads to public availability of research findings in an international group of experts in the context of the OPEN Project.We will systematically search Web of Knowledge for highly cited articles that provide a definition of biases related to the dissemination of research findings. A specifically designed data extraction form will be developed and pilot-tested. Working in teams of two, we will independently extract relevant information from each eligible article.For the development of a new framework we will construct an initial table listing different levels and different hazards en route to making research findings public. An international group of experts will iteratively review the table and reflect on its content until no new insights emerge and consensus has been reached. DISCUSSION: Results are expected to be publicly available in mid-2013. This systematic review together with the results of other systematic reviews of the OPEN project will serve as a basis for the development of future policies and guidelines regarding the assessment and prevention of publication bias.

Systematic review protocol to define classical IgE-associated diseases from birth to adolescence: the MeDALL study

BACKGROUND: Classical disease phenotypes are mainly based on descriptions of symptoms and the hypothesis that a given pattern of symptoms provides a diagnosis. With refined technologies there is growing evidence that disease expression in patients is much more diverse and subtypes need to be defined to allow a better targeted treatment. One of the aims of the Mechanisms of the Development of Allergy Project (MeDALL,FP7) is to re-define the classical phenotypes of IgE-associated allergic diseases from birth to adolescence, by consensus among experts using a systematic review of the literature and identify possible gaps in research for new disease markers. This paper describes the methods to be used for the systematic review of the classical IgE-associated phenotypes applicable in general to other systematic reviews also addressing phenotype definitions based on evidence. METHODS/DESIGN: Eligible papers were identified by PubMed search (complete database through April 2011). This search yielded 12,043 citations. The review includes intervention studies (randomized and clinical controlled trials) and observational studies (cohort studies including birth cohorts, case-control studies) as well as case series. Systematic and non-systematic reviews, guidelines, position papers and editorials are not excluded but dealt with separately. Two independent reviewers in parallel conducted consecutive title and abstract filtering scans. For publications where title and abstract fulfilled the inclusion criteria the full text was assessed. In the final step, two independent reviewers abstracted data using a pre-designed data extraction form with disagreements resolved by discussion among investigators. DISCUSSION: The systematic review protocol described here allows to generate broad,multi-phenotype reviews and consensus phenotype definitions. The in-depth analysis of the existing literature on the classification of IgE-associated allergic diseases through such a systematic review will 1) provide relevant information on the current epidemiologic definitions of allergic diseases, 2) address heterogeneity and interrelationships and 3) identify gaps in knowledge.
