European guidelines for sclerotherapy in chronic venous disorders.

AIM: Sclerotherapy is the targeted chemical ablation of varicose veins by intravenous injection of a liquid or foamed sclerosing drug. The treated veins may be intradermal, subcutaneous, and/or transfascial as well as superficial and deep in venous malformations. The aim of this guideline is to give evidence-based recommendations for liquid and foam sclerotherapy. METHODS: This guideline was drafted on behalf of 23 European Phlebological Societies during a Guideline Conference on 7-10 May 2012 in Mainz. The conference was organized by the German Society of Phlebology. These guidelines review the present state of knowledge as reflected in published medical literature. The regulatory situation of sclerosant drugs differs from country to country but this has not been considered in this document. The recommendations of this guideline are graded according to the American College of Chest Physicians Task Force recommendations on Grading Strength of Recommendations and Quality of Evidence in Clinical Guidelines. RESULTS: This guideline focuses on the two sclerosing drugs which are licensed in the majority of the European countries, polidocanol and sodium tetradecyl sulphate. Other sclerosants are not discussed in detail. The guideline gives recommendations concerning indications, contraindications, side-effects, concentrations, volumes, technique and efficacy of liquid and foam sclerotherapy of varicose veins and venous malformations.

Le Christ au miroir de la photographie contemporaine (1981-2011)

Depuis une trentaine d'années, les représentations de la figure de Jésus se sont multipliées en photographie. De la séquence narrative du photographe américain Duane Michals (Christ in New York, 1981) au chemin de croix de Wim Delvoye (Viae Crucis, 2006), en passant par la série I.N.R.I. (1997-98) de Bettina Rheims, les Photographies apocryphes (1994-98) d'Olivier Christinat, les Seven Bible Scenes (1998) de Rauf Mamedov, Ecce homo (1996-98) d'Elisabeth Ohlson, Jesus is my Homeboy (2003) de David LaChapelle ou encore South Soudan (2006) de Vanessa Beecroft, l'intérêt pour la figure christique dans le champ profane est incontestable. Le phénomène dépasse d'ailleurs les frontières géographiques, culturelles et confessionnelles.¦Cette thèse de doctorat réunit un important fonds iconographique qui démontre l'intérêt actuel pour la figure du Christ et la grande diversité des démarches et des profils des artistes. Cet important corpus est analysé selon trois perspectives. La première partie est consacrée au médium photographique, à ses liens étroits avec la sainte Face depuis le cliché du suaire de Turin en 1898, et depuis l'ambitieux projet photographique (1898) de Fred Holland Day qui incame le Christ dans ses nombreuses réinterprétations de la vie de Jésus.¦La deuxième partie de ce travail interroge l'emploi des formules iconographiques chrétiennes archétypales et questionne les références christiques utilisées par les artistes au travers de poses, d'attitudes, de gestes repris de chefs-d'oeuvre de l'art religieux, tant dans le domaine de la photographie d'art que dans la publicité ou la photographie de presse. L'usage du texte, la place des Ecritures dans les projets actuels sont aussi abordés, notamment autour de la question de la possibilité de raconter la vie de Jésus et des stratégies de mises en scène employées pour traduire les récits en images.¦Enfin, la dernière partie porte plus particulièrement sur les usages de la figure de Jésus, souvent alter ego de l'artiste, mais surtout porte-parole. À la suite des luttes socio- politiques des années 1970, la figure de Jésus est réinvestie par les minorités et Jésus incarne alors les combats d'artistes qui se réapproprient la représentation du Christ pour qu'elle corresponde à l'image qu'ils voient dans leur propre miroir (ex. Renee Cox, Yo Mama's Last Supper, 1996). Cet usage revendicateur, souvent doublé d'un goût non dissimulé pour la provocation (ex. Andres Serrano, Piss Christ, 1987), a souvent suscité la polémique. La question de la réception des oeuvres constitue un point essentiel de cette recherche qui tâche d'analyser la figure christique au miroir de la photographie contemporaine et qui conclut que le Christ est en réalité miroir des artistes eux-mêmes.

Inter-rater agreement and reliability of the COSMIN (COnsensus-based Standards for the selection of health status Measurement Instruments) Checklist

Background: The COSMIN checklist is a tool for evaluating the methodological quality of studies on measurement properties of health-related patient-reported outcomes. The aim of this study is to determine the inter-rater agreement and reliability of each item score of the COSMIN checklist (n = 114). Methods: 75 articles evaluating measurement properties were randomly selected from the bibliographic database compiled by the Patient-Reported Outcome Measurement Group, Oxford, UK. Raters were asked to assess the methodological quality of three articles, using the COSMIN checklist. In a one-way design, percentage agreement and intraclass kappa coefficients or quadratic-weighted kappa coefficients were calculated for each item. Results: 88 raters participated. Of the 75 selected articles, 26 articles were rated by four to six participants, and 49 by two or three participants. Overall, percentage agreement was appropriate (68% was above 80% agreement), and the kappa coefficients for the COSMIN items were low (61% was below 0.40, 6% was above 0.75). Reasons for low inter-rater agreement were need for subjective judgement, and accustom to different standards, terminology and definitions.Conclusions: Results indicated that raters often choose the same response option, but that it is difficult on item level to distinguish between articles. When using the COSMIN checklist in a systematic review, we recommend getting some training and experience, completing it by two independent raters, and reaching consensus on one final rating. Instructions for using the checklist are improved.

Young infants' triangular communication with their parents in the context of maternal postpartum psychosis: Four case studies

With increasing data on the dynamics of normative couples as they transition to parenthood and become a triad, the need for greater understanding of the impact of parental psychopathology on this transition has become clear. The goal of the current article is to begin exploring this area that has received little attention to date, by describing case examples from a study of clinical families as they transitioned to parenthood. Four representative cases were selected from a pool of 13 mother-father-baby triads, for whom the mother had been hospitalized conjointly with her infant due to a psychotic episode during the postpartum period. The families were observed as part of a clinical consultation that included a semistructured play paradigm known as the Lausanne Trilogue Play (LTP; E. Fivaz-Depeursinge, & A. Corboz-Warnery, 1999). Interactions were scored using standardized measures as well as clinical impressions. All families from the clinical sample were noted to struggle and frequently failed to achieve the goals of play. The impact on the infants in terms of their developing sense of self as well as their defensive strategies in this context are discussed, with clinical implications explored.

Assessment of construct validity of a virtual reality laparoscopy simulator.

BACKGROUND: The aim of this study was to assess whether virtual reality (VR) can discriminate between the skills of novices and intermediate-level laparoscopic surgical trainees (construct validity), and whether the simulator assessment correlates with an expert's evaluation of performance. METHODS: Three hundred and seven (307) participants of the 19th-22nd Davos International Gastrointestinal Surgery Workshops performed the clip-and-cut task on the Xitact LS 500 VR simulator (Xitact S.A., Morges, Switzerland). According to their previous experience in laparoscopic surgery, participants were assigned to the basic course (BC) or the intermediate course (IC). Objective performance parameters recorded by the simulator were compared to the standardized assessment by the course instructors during laparoscopic pelvitrainer and conventional surgery exercises. RESULTS: IC participants performed significantly better on the VR simulator than BC participants for the task completion time as well as the economy of movement of the right instrument, not the left instrument. Participants with maximum scores in the pelvitrainer cholecystectomy task performed the VR trial significantly faster, compared to those who scored less. In the conventional surgery task, a significant difference between those who scored the maximum and those who scored less was found not only for task completion time, but also for economy of movement of the right instrument. CONCLUSIONS: VR simulation provides a valid assessment of psychomotor skills and some basic aspects of spatial skills in laparoscopic surgery. Furthermore, VR allows discrimination between trainees with different levels of experience in laparoscopic surgery establishing construct validity for the Xitact LS 500 clip-and-cut task. Virtual reality may become the gold standard to assess and monitor surgical skills in laparoscopic surgery.

La communication intersubjective du bébé dans le triangle primaire

L'étude de la communication à trois entre le bébé, le père et la mère au travers du jeu du trilogue lausannois montre que la communication intersubjective dans la famille suit la même trajectoire développementale que la communication intersubjective à deux entre le bébé et sa mère ou son père : d'une forme primaire ou directe, elle évolue vers une forme secondaire ou référentielle, pour intégrer ensuite des formes symbolique et morale et enfin narrative.

Fatores associados à atenção domiciliária: subsídios à gestão do cuidado no âmbito do SUS

A identificação de variáveis associadas ao tipo de atenção domiciliária (AD) dos usuários do Sistema Único de Saúde (SUS) contribui para a gestão do cuidado na Rede de Atenção à Saúde (RAS). Objetiva-se identificar variáveis associadas ao tipo de AD dos usuários em Unidades Básicas de Saúde (UBS) selecionadas de Belo Horizonte. Estudo transversal em duas UBS com todos os usuários (n=114) em AD da área de abrangência. Utilizou-se a análise de regressão logística múltipla para seleção (stepwise) de variáveis significativas. Obteve-se maior comprometimento clínico dos usuários (OR=27,47), estado emocional triste (OR=24,36), risco para úlcera por pressão pela escala de Braden (OR=7,6) e a semidependência para as AVD pelo índice de Katz (OR=63,8) como fortemente associadas ao tipo de AD (p < 0,05). As variáveis fundadas no contexto social, familiar e clínico dos sujeitos subsidiam a abordagem integral e a tomada de decisão da equipe de saúde.

Sistema de Informação de Controlo de Assiduidade: Proposta para o caso da UniCV

Na Universidade de Cabo Verde (UniCV) o registo de entrada saída, faltas e marcação de férias são processos que ainda são feitos num livro de ponto manualmente e sem qualquer controlo rígido e efectivo. Este factor torna difícil o seu controlo por parte dos Recursos Humanos, seja em tempo real ou de forma periódica. O objectivo desta tese foi modelar e propor um protótipo de um sistema de informação que permitisse a informatização do registo de assiduidade e permitisse também a gestão dos períodos de férias sob a forma de portal Web. Apoiada na análise do Sistema de Registo de Assiduidade (SRA) da Universidade de Aveiro e das soluções existentes comercialmente foi feita uma análise e modelação do processo tendo em vista a evolução do sistema actual. O resultado foi um modelo de sistema de apoio à assiduidade que para além de integrar requisitos doutros sistemas (e.g. SRA) incorporou os requisitos essenciais relacionados com vários constrangimentos existentes actualmente. De forma a ilustrar as utilizações principais de um possível sistema de apoio à assiduidade para a UniCV foi implementado um protótipo. O protótipo, conforme expectável, não é um sistema pronto a entrar em produção mas pode constituir um bom suporte a uma eventual solução desenvolvida com este fim para a UniCV.
