Evaluation of prenatal diagnosis of congenital heart disease in a regional controlled case study.

AIMS: This study evaluated the evolution of the prenatal diagnosis of congenital heart disease (CHD) between 2003 and 2008 and its repercussion for the CHD prevalence rate at birth in a well-defined population (Canton of Vaud, Switzerland). METHODS AND RESULTS: All 572 cases of CHD reported in the Eurocat Registry of Vaud-Switzerland between 1.5.2003 and 31.12.2008 were analysed and compared with the cases in our clinical database. CHD cases were divided into five different groups according to heart disease severity. The prenatal detection rates increased significantly between 2003 and 2008, with a mean detection rate of 25.2%. There was a significantly higher rate of prenatal diagnosis in the first four groups of CHD severity, with the highest detection rate (87.5%) found in the group with the most severe CHD (group 1). In this group, 85.7% of cases resulted in a termination of pregnancy, and there was a consequent 75% reduction in the prevalence of severe major cardiac malformation at birth. Detection rates were 66% in group 2, 68.6% in group 3, and the lowest in groups 4 and 5, with rates of 25.9% and 12.9%, respectively. CONCLUSION: This study shows that the prenatal detection rate for CHD increased in a well-defined population over the study period. Prenatal diagnosis thus has had a major impact on patients with the most severe types of CHD and has resulted in a significant reduction in severe CHD at birth.

Quantification de la perfusion rénale par échographie de contraste, une étude pilote

Mise en perspective Le rein est un organe vital dont la fonction dépend en grande partie d'une perfusion tissulaire adéquate. Les techniques actuellement utilisées pour étudier la microcirculation rénale sont soit invasives soit très dispendieuses. L'échographie de contraste est une nouvelle technologie, non invasive, facile à réaliser au lit du malade et pour laquelle certaines techniques récemment présentées semblent permettre de quantifier la perfusion d'un organe. Une telle technique pourrait avoir des applications dans l'étude de l'insuffisance rénale aiguë. Buts de l'étude Notre étude vise à tester le potentiel de l'échographie de contraste pour détecter des modifications de la perfusion rénale, corticale et médullaire chez l'être humain. Plan de l'étude Nous avons étudié la microcirculation rénale par échographie de contraste chez 12 sujets sains. Les mesures ont été réalisées en baseline puis sous perfusion de doses croissantes d'angiotensine II (un puissant et spécifique vasoconstricteur rénal) et enfin après la prise orale d'un comprimé de Captopril (un puissant vasodilatateur rénal). Les valeurs obtenues par échographie de contraste ont été comparées à la perfusion globale rénale évaluée par la clairance du PAH, qui constitue le gold standard en physiologie rénale. Résultats principaux Le protocole a pu être réalisé sans complication. Les perfusions vasoactives ainsi que les différentes administrations de Sonovue ont été parfaitement tolérées. Les séquences vidéos ont été analysées par deux lecteurs et une bonne concordance a été trouvée. Nous avons trouvé une diminution statistiquement significative et dose dépendante de l'index de perfusion rénale lors de la perfusion d'angiotensine II: -45% (p<0.02) entre baseline et Ang II faible dose et -65% (p<0.01) entre baseline et Ang II à haute dose. Enfin, nous avons observé une hausse significative de cet indice après administration orale de Captopril (+35%, p>0.2). Ces changements étaient parallèles aux changements de flux plasmatique rénal mesurés par calcul de la clairance du PAH. Une corrélation moyenne mais significative (r=0.57, p=0.002) a été observée entre ces deux mesures. Conclusions et perspectives L'échographie de contraste est capable de détecter des modifications dans la microcirculation rénale induites par une perfusion d'angiotensine et ou une administration de Captopril. Il s'agit d'une technique rapide sensible et fiable qui pourrait participer à l'évaluation des patients souffrant d'insuffisance rénale aiguë. D'autres études sont nécessaires pour démontrer son utilité dans un contexte clinique.

Continuous determination of optimal cerebral perfusion pressure in traumatic brain injury.

OBJECTIVES: We have sought to develop an automated methodology for the continuous updating of optimal cerebral perfusion pressure (CPPopt) for patients after severe traumatic head injury, using continuous monitoring of cerebrovascular pressure reactivity. We then validated the CPPopt algorithm by determining the association between outcome and the deviation of actual CPP from CPPopt. DESIGN: Retrospective analysis of prospectively collected data. SETTING: Neurosciences critical care unit of a university hospital. PATIENTS: A total of 327 traumatic head-injury patients admitted between 2003 and 2009 with continuous monitoring of arterial blood pressure and intracranial pressure. MEASUREMENTS AND MAIN RESULTS: Arterial blood pressure, intracranial pressure, and CPP were continuously recorded, and pressure reactivity index was calculated online. Outcome was assessed at 6 months. An automated curve fitting method was applied to determine CPP at the minimum value for pressure reactivity index (CPPopt). A time trend of CPPopt was created using a moving 4-hr window, updated every minute. Identification of CPPopt was, on average, feasible during 55% of the whole recording period. Patient outcome correlated with the continuously updated difference between median CPP and CPPopt (chi-square=45, p<.001; outcome dichotomized into fatal and nonfatal). Mortality was associated with relative "hypoperfusion" (CPP<CPPopt), severe disability with "hyperperfusion" (CPP>CPPopt), and favorable outcome was associated with smaller deviations of CPP from the individualized CPPopt. While deviations from global target CPP values of 60 mm Hg and 70 mm Hg were also related to outcome, these relationships were less robust. CONCLUSIONS: Real-time CPPopt could be identified during the recording time of majority of the patients. Patients with a median CPP close to CPPopt were more likely to have a favorable outcome than those in whom median CPP was widely different from CPPopt. Deviations from individualized CPPopt were more predictive of outcome than deviations from a common target CPP. CPP management to optimize cerebrovascular pressure reactivity should be the subject of future clinical trial in severe traumatic head-injury patients.

Quelles applications raisonnables pour l'anticoagulation régionale au citrate en épuration extrarénale [What reasonable applications for regional citrate anticoagulation in renal replacement therapy?].

Regional citrate anticoagulation of the extracorporeal circuits (CRA) experienced considerable growth over the past decade. This development is partly explained by the significant progresses made in the field of bioengineering. These allow a secure administration of citrate, while an increasing availability of ionized calcium measurement at the bedside allows reactivity in monitoring the treatment. An increasing severity of the medical condition of patients requiring blood purification treatment gives more contrast to the profile of patient who may benefit from a CRA. If some methods of renal replacement therapy are well suited to this mode of anticoagulation, others are, to date, only at the stage of development and are applied under close medical supervision.

Comparative assessement of intimal hyperplasia development after 14 days in two different experimental settings : tissue culture versus ex vivo continuous perfusion of human saphenous vein

Résumé de l'article : L'hyperplasie intimale est un processus de remodelage vasculaire ubiquitaire après une lésion, pouvant menacer la perméabilité de tout type de reconstruction vasculaire. Les mécanismes physiopathologiques impliqués dans le développement de l'hyperplasie intimale ne sont que partiellement élucidés. Il est par conséquent nécessaire d'effectuer des recherches complémentaires afin d'en améliorer la compréhension et ainsi permettre l'élaboration de nouvelles stratégies thérapeutiques médicamenteuses. La culture de veines en milieu statique permet le développement de l'hyperplasie intimale. Ce modèle maintient la viabilité tissulaire, comme décrit précédemment dans d'autres études, mais empêche l'analyse des paramètres hémodynamiques. La mise au point d'un modèle de perfusion in vitro permettant la perfusion de segments vasculaires représente une approche expérimentale intégrant les différents facteurs hémodynamiques. Le système de perfusion (Ex Vivo Vein Support System) que nous avons élaboré conserve l'intégrité pariétale ainsi que les propriétés vasomotrices des veines pour une durée de 14 jours. Cette étude démontre que les deux modèles permettent le développement de l'hyperplasie intimale. Toutefois, les propriétés vasomotrices ainsi que l'influence des paramètres hémodynamiques ne peuvent être analysées que par l'utilisation du système de perfusion. Ce dernier a permis de perfuser des vaisseaux humains sans contamination bactérienne tout en maintenant l'intégrité cellulaire. Ce modèle de perfusion se rapproche plus des conditions hémodynamiques rencontrées in vivo que le modèle statique. Abstract : Background. Intimal hyperplasia (IH) is a vascular remodeling process which often leads to failure of arterial bypass or hemodialysis access. Experimental and clinical work have provided insight in IH development; however, further studies under precise con-trolled conditions are required to improve therapeutic strategies to inhibit IH development. Ex vivo perfusion of human vessel segments under standardized hemodynamic conditions may provide an adequate experimental approach for this purpose. Therefore, chronically perfused venous segments were studied and compared to traditional static culture procedures with regard to functional and histomorphologic characteristics as well as gene expression. Materials and methods. Static vein culture allowing high tissue viability was performed as previously described. Ex vivo vein support system (EVVSS) was performed using a vein support system consisting of an incubator with a perfusion chamber and a pump. EVVSS allows vessel perfusion under continuous flow while maintaining controlled hemodynamic conditions. Each human saphenous vein was divided in two parts, one cultured in a Pyrex dish and the other part perfused in EVVSS for 14 days. Testing of vasomotion, histomorphometry, expression of CD 31, Factor VIII, MIB 1, α-actin, and PAI-1 were determined before and after 14 days of either experimental conditions. Results, Human venous segments cultured under traditional or perfused conditions exhibited similar IH after 14 days as shown by histomorphometry. Smooth-muscle cell ( SMC) was preserved after chronic perfusion. Although integrity of both endothelial and smooth-muscle cells appears to be maintained in both culture conditions as confirmed by CD31, factor VIII and α-actin expression, a few smooth-muscle cells in the media stained positive for factor VIII. Cell-proliferation marker MIB-1 was also detected in the two settings and PAI-1 mRNA expression and activity increased significantly after 14 days of culture and perfusion. Conclusion. This study demonstrates the feasibility to chronically perfuse human vessels under sterile conditions with preservation of cellular integrity and vascular contractility. To gain insights into the mechanisms leading to IH, it will now be possible to study vascular remodeling not only under static conditions but also in hemodynamic environment mimicking as closely as possible the flow conditions encountered in reconstructive vascular surgery.

Regional economic growth and human capital: the role of overeducation

This article analyses the link between human capital and regional economic growth in the European Union. Using various indicators of human capital calculated from census microdata, we conclude that the recent economic performance of European regions is associated with an increase in overeducation. In fact, measures of educational mismatch seem to be more strongly connected to regional economic performance than do other traditional measures of human capital stock.

Postmortem angiography after vascular perfusion with diesel oil and a lipophilic contrast agent.

OBJECTIVE: The objective of our study was to establish optimal perfusion conditions for high-resolution postmortem angiography that would permit dynamic visualization of the arterial and venous systems. MATERIALS AND METHODS: Cadavers of two dogs and one cat were perfused with diesel oil through a peristaltic pump. The lipophilic contrast agent Lipiodol Ultra Fluide was then injected, and angiography was performed. The efficiency of perfusion was evaluated in the chick chorioallantoic membrane. RESULTS: Vessels could be seen up to the level of the smaller supplying and draining vessels. Hence, both the arterial and the venous sides of the vascular system could be distinguished. The chorioallantoic membrane assay revealed that diesel oil enters microvessels up to 50 microm in diameter and that it does not penetrate the capillary network. CONCLUSION: After establishing a postmortem circulation by diesel oil perfusion, angiography can be performed by injection of Lipiodol Ultra Fluide. The resolution of the images obtained up to 3 days after death is comparable to that achieved in clinical angiography.

Síndrome del dolor regional complejo tipo I en las fracturas del extremo distal del radio

Introducción: Las fracturas distales de radio (FDR) presentan diferentes resultadosfuncionales siendo desfavorables entre el 24% y el 31% de los casos. Una de lascomplicaciones más frecuentes es el síndrome del dolor regional complejo tipo I(SDRC-I), cuyo origen es desconocido. Sólo el 20-30% de los pacientes recuperarán sugrado de funcionalidad anterior.Objetivos: Estimar la prevalencia de SDRC-I tras una FDR de acuerdo a cuatro tipos detratamiento.Métodos: estudio de una serie de casos retrospectivos. La población de referencia hansido los 391 trabajadores afiliados a una Mutua en Cataluña y diagnosticados deFDR tras una lesión por accidente laboral durante lo años 2008-2010.Los casos han sido trabajadores accidentados que tras una FDR desarrollaron el SDRCI.Como variable dependiente se ha utilizado el diagnóstico de SDRC-I; como variablesindependientes el tipo de tratamiento, la edad, el sexo, la ocupación y el mecanismo dela lesión.Resultados: el 19,7% de la muestra ha desarrollado SDRC-I, siendo esta prevalenciasuperior en los pacientes intervenidos mediante la técnica de tracción bipolar o conagujas de Kirschner; 29,17% y 30,56% respectivamente, que para aquellos en los quese ha realizado un tratamiento conservador o una intervención quirúrgica con placa en Ty tornillos; 15,92% y 15,79%.Conclusiones El tratamiento conservador y la técnica quirúrgica de fijación con placaen T y tornillos han dado una menor prevalencia de SDRC-I.Los mecanismos de lesión asociados a una mayor fuerza presentan fracturas másinestables y requieren un tratamiento quirúrgico. Los tratamientos conservadores sonlos más usados en edades mayores relacionados con fracturas estables.A nivel clínico se extrae una recomendación profiláctica con Vitamina C para evitar laaparición de SDRC-I sobre los pacientes de edad comprendida entre los 36 y los 55años, con mecanismo lesional de caída o caída desde altura, intervenidos con agujas de Kirschner o tracción bipolar.

Regional income inequality in Italy in the long run (1871–2001). Patterns and determinants

The chapter presents up-to-date estimates of Italy’s regional GDP, with the present borders, in ten-year benchmarks from 1871 to 2001, and proposes a new interpretative hypothesis based on long-lasting socio-institutional differences. The inverted U-shape of income inequality is confirmed: rising divergence until the midtwentieth century, then convergence. However, the latter was limited to the centrenorth: Italy was divided into three parts by the time regional inequality peaked, in 1951, and appears to have been split into two halves by 2001. As a consequence of the falling back of the south, from 1871 to 2001 we record σ-divergence across Italy’s regions, i.e. an increase in dispersion, and sluggish β-convergence. Geographical factors and the market size played a minor role: against them are both the evidence that most of the differences in GDP are due to employment rather than to productivity and the observed GDP patterns of many regions. The gradual converging of regional GDPs towards two equilibria instead follows social and institutional differences − in the political and economic institutions and in the levels of human and social capital – which originated in pre-unification states and did not die (but in part even increased) in postunification Italy.

Favorable outcome of an acute complex regional pain syndrome with immunoglobulin infusions.

OBJECTIVE: To emphasize that complex regional pain syndrome (CRPS), a disabling disorder with the implication of aberrant inflammation, vasomotor dysfunction, and maladaptive neuroplasticity, might be treated with a high dose of intravenous immunoglobulin infusions (IVIG). METHODS: We describe a patient who presented with CRPS in the acute phase of the disease. RESULTS: The CRPS developed secondary to sciatic compression in a young patient and was treated within 10 days by high-dose IVIG (2 g/kg). It resolved completely within days after infusions. DISCUSSION: This observational study emphasizes that high-dose IVIG may be a treatment option in the acute phase of CRPS.
