Forgoing dental care for economic reasons in Switzerland: a six-year cross-sectional population-based study

BACKGROUND: While oral health is part of general health and well-being, oral health disparities nevertheless persist. Potential mechanisms include socioeconomic factors that may influence access to dental care in the absence of universal dental care insurance coverage. We investigated the evolution, prevalence and determinants (including socioeconomic) of forgoing of dental care for economic reasons in a Swiss region, over the course of six years. METHODS: Repeated population-based surveys (2007-2012) of a representative sample of the adult population of the Canton of Geneva, Switzerland. Forgone dental care, socioeconomic and insurance status, marital status, and presence of dependent children were assessed using standardized methods. RESULTS: A total of 4313 subjects were included, 10.6% (457/4313) of whom reported having forgone dental care for economic reasons in the previous 12 months. The crude percentage varied from 2.4% in the wealthiest group (monthly income ≥ 13,000 CHF, 1 CHF ≈ 1$) to 23.5% among participants with the lowest income (<3,000 CHF). Since 2007/8, forgoing dental care remained stable overall, but in subjects with a monthly income of <3,000 CHF, the adjusted percentage increased from 16.3% in 2007/8 to 20.6% in 2012 (P trend = 0.002). Forgoing dental care for economic reasons was independently associated with lower income, younger age, female gender, current smoking, having dependent children, divorced status and not living with a partner, not having a supplementary health insurance, and receipt of a health insurance premium cost-subsidy. CONCLUSIONS: In a Swiss region without universal dental care insurance coverage, prevalence of forgoing dental care for economic reasons was high and highly dependent on income. Efforts should be made to prevent high-risk populations from forgoing dental care.

Utilité de la recherche des autoanticorps dans la pratique quotidienne [Use of autoantibodies in clinical practice]

Autoantibodies are frequently determined in unclear clinical situations and in the context of an inflammatory syndrome. The aim of this article is not to review all autoantibodies in details, but to discuss those used in clinical practice by describing their methods of detection and interpretation. Thus we will focus on antinuclear antibodies (ANA), which are typically associated with connective tissue diseases, as well as anti-neutrophil cytoplasmic antibodies (ANCA), which are useful in the diagnosis of ANCA-associated vasculitides. Due to its high sensitivity indirect immunofluorescence is used as a screening test; when positive, ELISA is performed to search for antibodies more specifically associated with certain auto-immune diseases.

Small farmers of the Florida Province (Bolivia) : Reciprocity in Practice

Peasant societies are often seen by neoliberal or Marxist theorists as passive subjects of political-economic transformations occurring at a higher level, only surviving through acculturation to market requirements. By analyzing agricultural work organization in highland communities and a local system of water management called Acuerdos Reciprocos por el Agua (Reciprocal Agreements for Water), developed in 2003 by the Natura Bolivia foundation in Florida Province in Bolivia, we show that, contrary to this perception, traditional reciprocal norms still play an essential role in decision making. This suggests the agency of rural societies and the resilience of traditional reciprocity-based norms in mountain regions.

La pratique infirmière avancée [Advanced practice nursing].

Dans les sociétés contemporaines axées sur le savoir, plus grande sera la proportion de leur population détentrice d'une formation supérieure et engagée en recherche, plus avancé sera leur développement économique et social.1,2 Par contre, dans ces sociétés, le vieillissement de la population, l'importance ccordée aux soins de santé axés sur les maladies chroniques et les coûts financiers de ceux-ci exercent une forte pression sur les systèmes de santé. Les nterventions doivent donc être les plus efficaces possible, avec un rapport coût/efficacité optimal. Cela requiert que les infirmières soient capables d'oeuvrer en pratique avancée, c'est-à-dire capables de développer, implémenter et évaluer des approches cliniques infirmières basées sur des preuves, de tester de nouvelles interventions potentiellement plus efficientes et de promouvoir un programme de recherche portant explicitement sur l'amélioration de la qualité et sécurité des soins en contexte d'interdisciplinarité.

Pautas de conducta frente a los pacientes bajo tratamiento anticoagulante en la clínica dental.

Nuestro trabajo pretende dar unas ideas básicas para el manejo de pacientes sometidos a tratamiento anticoagulante dando a conocer las posibles pautas a seguir respecto a su medicación: mantener intacta la terapia anticoagulante, modificar la terapia anticoagulante o realizar tratamiento combinado de heparina con anticoagulantes orales. La decisión deberá tomarse conjuntamente con el hematólogo responsable del paciente valorando cada caso según la morbilidad intrínseca de la intervención, el riesgo de tromboembolismo en función de la patología de base que presente el paciente y el grado de coagulación determinado mediante estudios de laboratorio (tiempo de protrombina e índice de trombotest).

Liberación de mercurio por parte de las obturaciones de amalgama dental: tipo, cantidad, método de determinación y posibles efectos adversos

Las obturaciones dentales de amalgama constituyen la fuente principal de exposición permanente de bajo nivel al vapor de mercurio (Hg°) y al mercurio inorgánico (Hg(II)) para la población general. La dosis de mercurio absorbido procedente de la amalgama es de 2.7 ¿g/día/persona para una cantidad promedio de 7.4 obturaciones. Si esta cantidad consistiera enteramente en mercurio inorgánico (Hg(II)), estaría muy por debajo de la cifra de 15 ¿g/día para una persona de 65 kg que la OMS considera como ingesta tolerable de mercurio inorgánico. En el caso de una exposición permanente a la misma cantidad, pero de vapor de mercurio (Hg0), se obtendría una concentración de 0.18 mg/m3 que puede compararse con la concentración de referencia de la EPA de 0.3 mg/m3 o con el nivel de riesgo mínimo de la ATSDR de 0.2 mg/m3. Varios estudios clínicos longitudinales y aleatorizados han evaluado la relación entre la concentración urinaria de mercurio y la exposición al mercurio procedente de las obturaciones dentales de amalgama en niños, particularmente vulnerables al Hg0, así como los posibles efectos neurológicos de tal exposición. La concentración promedio de mercurio en orina en los niños tratados con amalgama, con un promedio de 18,7 superficies obturadas, aumentó hasta un pico de 3.2 ¿g/L a los 2 años de iniciado el tratamiento y a los 7 años de seguimiento había descendido hasta los niveles basales y no se detectó ninguna alteración en las distintas exploraciones de monitorización neuropsicológica. De la misma manera, diversas investigaciones epidemiológicas no han aportado ninguna evidencia del papel de la amalgama en la posible causa o exacerbación de trastornos degenerativos como la esclerosis lateral amiotrófica, la enfermedad de Alzheimer, la esclerosis múltiple o el Parkinson. La extracción de las obturaciones de amalgama produce un aumento transitorio de los niveles de mercurio en sangre inmediatamente después de extraer las obturaciones de amalgama, pero de pequeña magnitud y que se normaliza a los 100 días, por lo que el efecto del dique de goma tiene una relevancia toxicológica menor. La conclusión de esta revisión es que la amalgama dental continúa siendo un excelente material de obturación.

Riesgo de transmisión de enfermedades infecciosas en la clínica dental

Se presenta en este artículo una revisión del riesgo de transmisión de enfermedades infecciosas en la clínica dental. Las hepatitis víricas, en especial la hepatitis B y la C, la infección por el virus de la inmunodeficiencia humana, la tuberculosis, y otras enfermedades infecciosas pueden ser potencialmente transmitidas en el ejercicio de la profesión, tanto a los pacientes como a los profesionales. El conocimiento de la probabilidad de transmisión y sus características son la base sobre la que desarrollarán las medidas preventivas de control de infección que intentan evitar o por lo menos minimizar la probabilidad de adquirir estas enfermedades en el ámbito laboral.

Traitements de fer: preuves de t'efficacité et bonne pratique clinique [Iron therapy: proof of efficacy and good clinical practice].

Efficacy of iron therapy, whether oral or intravenous, on biological markers of body iron stores is well recognized in medical literature, but current studies are heterogeneous, of sometimes dubious quality, and rarely address clinical outcomes. Precise practical guidelines appear available only for indications related to kidney disease. First-line intravenous use is reserved for situations comprising chronic renal failure, or patients presenting with malabsorption syndromes such as in inflammatory bowel disease. In all other situations, because of the non-negligible risk of hypersensitivity reactions, intravenous iron use is considered justified only in clinically sustained indications, for patients in whom oral administration of iron is unsatisfactory or impossible.

EASL Clinical Practice Guidelines: Wilson's disease.

This Clinical Practice Guideline (CPG) has been developed to assist physicians and other healthcare providers in the diagnosis and management of patients with Wilson's disease. The goal is to describe a number of generally accepted approaches for diagnosis, prevention, and treatment of Wilson's disease. Recommendations are based on a systematic literature review in the Medline (PubMed version), Embase (Dialog version), and the Cochrane Library databases using entries from 1966 to 2011. The Grades of Recommendation, Assessment, Development, and Evaluation (GRADE) system used in other EASL CPGs was used and set against the somewhat different grading system used in the AASLD guidelines (Table 1A and B). Unfortunately, there is not a single randomized controlled trial conducted in Wilson's disease which has an optimal design. Thus, it is impossible to assign a high or even a moderate quality of evidence to any of the questions dealt with in these guidelines. The evaluation is mostly based on large case series which have been reported within the last decades.

Nature conservation efforts by forest owners : intentions and practice in a Swedish case study

Abstract

Utilité de la prophylaxie antibiotique avant un geste dentaire pour tes porteurs de prothèses totales du genou ou de la hanche [Antibiotic prophylaxis before dental procedures in arthroplasty patients]

Antibiotic prophylaxis is commonly prescribed to patients with total arthroplasties before a dental intervention. This attitude is not evidence-based for several reasons: 1) the usual pathogens of prosthetic joint infections are not of oral origin; 2) even if given, systemic antibiotic do not completely suppress the occult bacteraemia occurring during dental intervention and 3) humans may have up to twelve episodes of occult bacteraemia of dental origin per day. Routine antibiotic prophylaxis should be clearly distinguished from the antibiotic treatment required in case of established oral cavity infection. A constant optimal oral and dental hygiene is more important in terms of prevention and should be routinely recommended to every patient carrying a joint arthroplasty.

Prescription du monitoring pratique médicate: de l'empirisme eclairé aux stratégies rationnelles [Prescribing monitoring in clinical practice: from enlightened empiricism to rational strategies].

Monitoring of a medical condition is the periodic measurement of one or several physiological or biological variables to detect a signal regarding its clinical progression or its response to treatment. We distinguish different medical situations between diagnostic, clinical and therapeutic process to apply monitoring. Many clinical, variables can be used for monitoring, once their intrinsic properties (normal range, critical difference, kinetics, reactivity) and external validity (pathophysiological importance, predictive power for clinical outcomes) are established. A formal conceptualization of monitoring is being developed and should support the rational development of monitoring strategies and their validation through appropriate clinical trials.
