Valve dysfunction is a common cardiovascular pathology. Despite significant clinical research, there is little formal study of how valve dysfunction affects overall circulatory dynamics. Validated models would offer the ability to better understand these dynamics and thus optimize diagnosis, as well as surgical and other interventions. A cardiovascular and circulatory system (CVS) model has already been validated in silico, and in several animal model studies. It accounts for valve dynamics using Heaviside functions to simulate a physiologically accurate “open on pressure, close on flow” law. However, it does not consider real-time valve opening dynamics and therefore does not fully capture valve dysfunction, particularly where the dysfunction involves partial closure. This research describes an updated version of this previous closed-loop CVS model that includes the progressive opening of the mitral valve, and is defined over the full cardiac cycle. Simulations of the cardiovascular system with healthy mitral valve are performed, and, the global hemodynamic behaviour is studied compared with previously validated results. The error between resulting pressure-volume (PV) loops of already validated CVS model and the new CVS model that includes the progressive opening of the mitral valve is assessed and remains within typical measurement error and variability. Simulations of ischemic mitral insufficiency are also performed. Pressure-Volume loops, transmitral flow evolution and mitral valve aperture area evolution follow reported measurements in shape, amplitude and trends. The resulting cardiovascular system model including mitral valve dynamics provides a foundation for clinical validation and the study of valvular dysfunction in vivo. The overall models and results could readily be generalised to other cardiac valves. [less ▲]

In health care organizations, the need for 24-hour care increases the number of patient’s transfer. Handover and shift changes are now recognized as particularly critical moments for the reliability of care. However, few studies focused specifically on how physicians share relevant information during these moments. Moreover, emergency departments are known to be extremely vulnerable to error, because of high time pressure, frequent interruptions, high variability and number of patients, etc. Our study aimed to estimate how emergency physicians share information about a patient during handover, and to evaluate the impact of a procedure of medical handover standardization. To do this, we conducted a pre-post test on completeness of transmissions. We first performed observations of 50 physicians’ shift changes in an emergency department. All of these were video-recorded and then analyzed. We classified communications into seven categories (identifying information, current pathology, patient’s current status, significant patient’s tests results, priority medical interventions, diagnose and recommendations, and dispositions). After these observations, we elaborated and implemented a standardization procedure, according to literature, analyses of our observations and physicians’ recommendations. We finally assessed this procedure by observing and analyzing 40 handovers, using the same method as previously described. We also evaluated the physician’s opinion about the quality of the transmission with a 7-point Likert scale. Our results showed three significant differences before and after the standardization of communications. Physicians share more information about patient’s tests results, priority interventions and dispositions. Moreover, we found a significant difference of the perceived quality of the standardized handover. [less ▲]

OBJECTIVES: Due to the recent interest in hands-only protocols for dispatcher-assisted cardiopulmonary resuscitation (CPR) and the lack of any validated algorithms in French, our primary objective was to evaluate a new French-language protocol in terms of its efficacy to help previously untrained volunteers in performing basic life support efforts of appropriate quality, and secondarily to investigate its potential utility in subjects with previous training. METHODS: Untrained volunteers were recruited among adults in a public movie centre and previously trained volunteers among undergraduate nursing students. Participants were randomly assigned to 'phone CPR' versus 'no phone CPR' by drawing sets of envelopes. Primary outcome measures were the results of the Cardiff evaluation test; the secondary measures were global scoring of a complete 5min period of CPR, in a manikin model of cardiac arrest. RESULTS: Out of 146 volunteers assessed for eligibility, 36 previously untrained candidates declined participation. 110 participants, distributed into four groups, completed the study: the previously untrained non-guided group (group A, n=30), the previously untrained guided group (group B, n=30), the previously trained non-guided group (group C, n=25) and the previously trained guided group (group D, n=25). Results of the Cardiff test and global evaluation of CPR performance revealed a significant improvement in group B as compared with group A, approaching the level of the group C. Previously trained guided bystanders had the best CPR scores, notably because of an improvement in the quality of airway management. CONCLUSION: When used by dispatchers, this new French-language algorithm offers the opportunity to help previously untrained bystanders initiate CPR. The same protocol may serve to guide volunteers with prior basic life support training to reach their best CPR performance. [less ▲]

The congenital long QT syndrome (LQTS) is a hereditary cardiac disease characterized by a prolongation of the QT interval > 440 ms at rest ECG associated with a high risk of ventricular arrhythmias (torsade de pointe). Clinical manifestations are syncope and sudden cardiac death. The implicated genes encode cardiac ion channel subunits or proteins involved in modulating ionic currents. The diagnosis of LQTS can be complex in borderline cases. Etiology, pathogenesis, diagnosis and treatment are discussed. [less ▲]

RÉ SUMÉ : Le syndrome hémolytique urémique (SHU ) est une affection assez rare chez l’adulte, mais de pronostic réservé. Il traduit une microangiopathie thrombotique essentiellement rénale. Nous rapportons l’histoire d’un jeune patient dont la présentation et l’exploration cliniques rendent le diagnostic de SHU probable. La présentation quelque peu atypique offre non seulement l’occasion de discuter des différents éléments qui plaident en faveur du diagnostic selon les hypothèses physiopathologiques les plus récentes, mais aussi de redéfinir les recommandations de la prise en charge en urgence de cette affection sévère.

L’interaction entre le ventricule et le réseau vasculaire est un déterminant majeur de la performance cardiaque globale, particulièrement en présence d’une insuffisance ventriculaire préalable. L’évaluation du couplage ventriculoartériel grâce à la mesure de l’élastance ventriculaire, comme reflet de la contractilité et de l’élastance artérielle, en tant qu’indice de post-charge, permet de quantifier cette interaction. Des travaux récents illustrent l’intérêt clinique de ce concept. Jusqu’à présent, son utilisation restait toutefois marginale en raison de la nécessité de recourir à des mesures invasives et complexes. Le développement des techniques d’imagerie non invasive et de traitement des signaux permet actuellement d’envisager l’utilisation de ce concept en pratique clinique courante. [less ▲]

Epiploic appendagitis is the term used to describe the inflammation of an epiploic appendage. These small masses of fat distributed along the colon, from the caecum to the recto-sigmoid junction can inflammate by torsion, spontaneously or secondarily with the inflammation of an anatomical structure in the neighbourhood. Symptomatology may mimic retro-caecal appendicitis or diverticulitis and the diagnosis by CT avoids unnecessary surgery or hospitalization. Indeed, under conservative treatment by AINS and analgesics, symptomatology regresses in about five days. In this article, we relate the case of a patient with a typical clinical presentation, to remind the elements of this pathological entity. [less ▲]
