Fibropapilomatosis oral múltiple como manifestación inicial de Síndrome de Cowden: caso clínico

El síndrome de Cowden es una infrecuente enfermedad hereditaria englobada dentro de las poliposis gastrointestinales de tipo hamartomatoso. Se caracteriza por asociar anomalías cutaneomucosas y por la extraordinaria tendencia a desarrollar neoplasias malignas, principalmente de mama y tiroides. La importancia de un diagnóstico precoz del síndrome y de un adecuado screening tumoral en pacientes con lesiones papilomatosas cutaneomucosas, nos va a permitir adelantarnos en el diagnóstico de patologías con enorme morbimortalidad asociada en caso de una detección tardía. Presentamos el caso de una paciente diagnosticada de síndrome de Cowden tras consultar por lesiones papilomatosas labiales de largo tiempo de evolución y tratada posteriormente de cáncer de mama y riñón en estadios iniciales. El correcto diagnóstico de una patología banal de mucosa oral, nos ha permitido actuar de manera muy precoz frente a la patología neoplásica asociada a dicha enfermedad.Cowden syndrome is a rare hereditary disease included within hamartoma-type gastrointestinal polyposis. It is characterised by associated mucocutaneous anomalies and by the extraordinary tendency to develop malignant neoplasia, mainly in the breast and thyroid. Early diagnosis of the syndrome and adequate tumoral screening in patients with mucocutaneous papillomatosis make it possible to make an earlier diagnosis of associated pathologies which have great morbidity when detected late. We present the case of a patient diagnosed with Cowden syndrome after consultation for labial papillomatous lesions of long evolution who was subsequently treated for breast and kidney cancer in initial stages. The correct diagnosis of a banal pathology of oral mucosa made it possible for us to take early action against the neoplastic pathology associated with this disease

Précarité et nouvelles formes d'emploi : quatre études sectorielles en région Rhône-Alpes : bilan qualitatif : mars 2008-décembre 2008

Ce rapport propose de cerner ce qu'est la précarité d'une part, et d'approfondir les différentes réalités de cette précarité d'autre part. La première partie du rapport permettra d'approcher cette réalité complexe qu'est la précarité dans l'emploi. Développer le dialogue social territorial sur la précarité dans l'emploi nécessite de disposer d'une vision commune de sa nature, de ses développements et de ses enjeux. Dans une seconde partie, des diagnostics très poussés dans chacun des secteurs retenus, à savoir la logistique, les services à la personne, le tourisme-loisir, les pôles de compétitivité, sont développés. Le programme sur la précarité et les nouvelles formes d'emploi essaie de croiser les réalités constatées dans ces quatre secteurs de l'économie et quatre régions européennes (Rhône-Alpes, Lombardie, Catalogne, Bade-Wurtemberg).précarité ; emploi ; analyse sectorielle ; travail précaire ; travailleur saisonnier ; condition de travail ; France ; Italie ; Espagne ; Allemagne ; Rhône-Alpes ; Lombardie ; Catalogne ; Bade-Wurtemberg

A Comparison of Two Function-Based Interventions: NCR vs. DRO in a Preschool Classroom

The purpose of this study was to determine the relative efficacy of non-contingent reinforcement (NCR) and differential reinforcement of other behavior (DRO) after behavioral functions have been identified through indirect, descriptive, and experimental assessment. Participants included three preschool-age children in center-based classrooms (Head Start) in a southeastern school district. Functional assessment data were used to inform treatment procedures, which were examined with an alternating treatments design. This study examined (1) relative differences in the efficacy of NCR and DRO in decreasing problem behaviors in preschool children, (2) relative differences in the efficacy of NCR and DRO in increasing appropriate behavior, (3) relative preference for functional assessment procedures, and (4) differential preference for NCR versus DRO for preschool teachers

Maintenance and Generalization of Preschool Teachers\u27 Use of Behavior Specific Praise Following In Situ Training

This study tested the efficacy of in situ training via a multiple baseline design across participants for increasing four Head Start teachers’ use of behavior specific praise (BSP) in classroom settings while evaluating concomitant changes in their classes’ behavior. Of further interest was the extent to which Head Start teachers maintained and generalized use of BSP in untrained settings. The results of this study indicate that in situ training was effective for increasing Head Start teachers’ use of BSP above baseline rates and generally maintained above a predetermined criterion (i.e., .5 BSP statements per minute). Data also indicate that Head Start teachers generalized use of BSP to untrained settings. Finally, increases in Head Start children’s appropriately engaged behavior and decreases in disruptive behavior were observed in trained and untrained settings. The results of this study are discussed in terms of its extension of the school-based consultation literature, its limitations, future directions for research, and implications for applied practice

Drop Traffic in Microfluidic Ladder Networks with Fore-Aft Structural Asymmetry

We investigate the dynamics of pairs of drops in microfluidic ladder networks with slanted bypasses, which break the fore-aft structural symmetry. Our analytical results indicate that unlike symmetric ladder networks, structural asymmetry introduced by a single slanted bypass can be used to modulate the relative drop spacing, enabling them to contract, synchronize, expand, or even flip at the ladder exit. Our experiments confirm all these behaviors predicted by theory. Numerical analysis further shows that while ladder networks containing several identical bypasses are limited to nearly linear transformation of input delay between drops, mixed combination of bypasses can cause significant non-linear transformation enabling coding and decoding of input delays.Comment: 4 pages, 5 figure

Design of Autonomous Gel Actuators

In this paper, we introduce autonomous gel actuators driven by chemical energy. The polymer gels prepared here have cyclic chemical reaction networks. With a cyclic reaction, the polymer gels generate periodical motion. The periodic motion of the gel is produced by the chemical energy of the oscillatory Belouzov-Zhabotinsky (BZ) reaction. We have succeeded in making synthetic polymer gel move autonomously like a living organism. This experimental fact represents the great possibility of the chemical robot

The Seismic Experiment for Interior Structure (SEIS): Experiment Data Distribution

The six sensors of SEIS (The Seismic Experiment for Interior Structure) [- one of three primary instruments on NASA's Mars Lander Insight] cover a broad range of the seismic bandwidth, from 0.01 hertz to 50 hertz, with possible extension to longer periods. Data are transmitted in the form of three continuous VBB (Very Broad-Band) components at 2 samples per second (sps), an estimation of the short period (SP) energy content from the SP at 1 sps, and a continuous compound VBB/SP vertical axis at 10 sps. The continuous streams are augmented by requested event data with sample rates from 20 to 100 sps. SEIS data products are downlinked from the spacecraft in raw CCSDS (Consultative Committee for Space Data Systems) packets and converted to both the Standard for the Exchange of Earthquake Data (SEED) format files and ASCII tables (GeoCSV) for analysis and archiving. Metadata are available in dataless SEED and StionXML. Time series data (waveforms) are available in miniseed and GeoCSV. Data are distributed according to FDSN (Federation of Digital Seismograph Networks - http://www.fdsn.org) formats and interfaces. Wind, pressure and temperature data from the Auxiliary Payload Sensor Suite (APSS) will also be available in SEED format, and can be used for decorrelation and diagnostic purposes on SEIS

Extracting the hydrodynamic resistance of droplets from their behavior in microchannel networks

The overall traffic of droplets in a network of microfluidic channels is strongly influenced by the liquid properties of the moving droplets. In particular, the effective hydrodynamic resistance of individual droplets plays a key role in their global behavior. We here propose two simple and low-cost experimental methods for measuring this parameter by analyzing the dynamics of a regular sequence of droplets injected into an "asymmetric loop" network. The choice of a droplet taking either route through the loop is influenced by the presence of previous droplets which modulate the hydrodynamic resistance of the branches they are sitting in. We propose to extract the effective resistance of a droplet from easily observable time series, namely from the choices the droplets make at junctions and from the inter-droplet distances. This becomes possible when utilizing a recently proposed theoretical model, based on a number of simplifying assumptions. We here present several sets of measurements of the hydrodynamic resistance of droplets, expressed in terms of a "resistance length". The aim is twofold, (1) to reveal its dependence on a number of parameters, such as the viscosity, the volume of droplets, their velocity as well as the spacing between them. At the same time (2), by using a standard measurement technique, we compare the limitations of the proposed methods. As an important result of this comparison we obtain the range of validity of the simplifying assumptions made in the theoretical model.Comment: 11 pages, 11 figure

School-based Consultation to Promote Generalization of Early Childhood Educators’ Evidence-based Practices: A Meta-analysis

Early childhood educators are tasked with supporting young children’s academic, behavioral, and social-emotional through the use of evidence-based practices (EBPs). Unfortunately, early childhood educators may struggle with consistent implementation of EBPs. When this occurs, school-based consultation may be beneficial in promoting early childhood educators’ use of effective classroom management practices and interventions. A critical aspect of school-based consultation is ensuring that early childhood educators generalize strategies they have been trained to use through consultation. However, the extent to which early childhood educators generalize skills trained through consultation across settings, children, and other evidence-based practices is unclear. Therefore, the purpose of this meta-analysis was to synthesize the existing school-based consultation literature in early childhood settings to determine the extent to which early childhood educators generalize skills trained through consultation. A total of 12 studies including 39 educator consultees and 171 effects comprised our final sample. Three-level hierarchical models with robust variance estimation were used to pool both Log Response Ratios and Tau effect sizes for analyses. Overall results indicated school-based consultation had a positive and significant impact on educator generalization of EBPs (LRRi = 0.95; Tau = 0.79). Further, particular implementation supports (e.g., in situ training) significantly contributed to EBP generalization. These results suggest school-based consultation to be an effective means for promoting early childhood educator generalization of EBPs. Implications for research and practice and future research directions are discussed
