Hypoperfusion can be difficult to diagnose clinically, especially in younger patients. Arterial Base Excess (BE) has been used as an early indicator of hypoperfusion. AIM To evaluate the prognostic value of admission BE in severe trauma patients admitted to the emergency department (ED). METHODS In this prospective study, severe trauma patients meeting high velocity criteria admitted to the ED during the study period were included. BE was calculated from arterial blood gas samples. Multivariate analysis was performed for Day-1 and Day-7 post trauma mortality. ROC characteristics and survival curves were used. RESULTS We included 479 patients. Median age was 37 (18-90). Eighty-one per cent were male. Clinical characteristics n(%): GCS<13: 170(35); SBP<90 mmHg: 64(13) and SpO2 <90%: 82(17). Mean ISS was 22 ± 13. Mortality was at days 1 and 7: 2.2% and ...

These images are diagnosed and commented, in different languages, by several specialists instantly. Moreover, it is necessary to employ new techniques, in order to automatically extract information and analyze knowledge from the huge number of comments expressing specialist’s analyzes and recommendations. For this reason, we propose a terms-based method in order to extract the relevant terms and words which can describe the medical image. Furthermore, significant extracted terms and keywords will be used later to index medical images, in order to facilitate their search through the social network site. In fact, we need to take account, in our work, that existing comments are expressed in different languages. So, it is essential to implement a multilingual indexation method to eliminate the ambiguity which will be the cause of the ef...

L'objectif de cette étude a été de décrire les caractéristiques épidémiologiques, cliniques, thérapeutiques et pronostiques des patients admis aux urgences pour ACD sévère ou modérée. Méthodes: il s'agissait d'une étude prospective, descriptive qui a inclus les ACD modérées ou sévères. Standardisation du protocole de prise en charge thérapeutique. Nous avons étudié les caractéristiques épidémiologiques, cliniques, thérapeutiques et pronostiques chez ces patients. Résultats: nous avons inclus 185 patients avec ACD sévère ou modérée. L'âge moyen a été de 38 +/-18 ans; le sexe ratio=0,94. Diabète connue= 159 patients (85%) dont 116 étaient des diabétiques type 1. Les facteurs de décompensation les plus fréquents étaient l'arrêt du traitement chez 42% et l'infection chez 32%. La glycémie moyenne a été de 32,7+/-12mmol/L, pH =7,14+/-0,13, HCO3-=7,2+/-3,56 mmol /L. La durée moyenne de l'insuline intraveineuse était de 17,3 +/-16 heures. L'hypoglycémie a été observée chez 26 patients (14%), l'hypokaliémie chez 80 (43%). La mortalité au cours de l'hospitalisation a été de 2,1%. Conclusion: l'acidocétose diabétique survient chez les sujets jeunes traités par insulinothérapie. Le traitement est à base d'insuline par voie intraveineuse en plus de la correction du déficit hydrique. Les complications sont essentiellement l'hypokaliémie et l'hypoglycémie; et la mortalité reste faible.

Most of the time, doctors can make mistakes leading to unpredictable damage in patients. In order to minimize medical errors by fostering collaboration between physicians and/or patients, we propose in this paper, as a first contribution, a medical social network destined to gather patients’ medical images and physicians’ annotations expressing their medical reviews and advice. As the volume of comments is very important, analysis of opinions becomes an impossible task and requires automatic processing to extract relevant information collected from the comments of specialists. For this purpose, we propose a second contribution of producing summaries of comments containing most current conditions and relevant words prescribed by doctors. Furthermore, this extracted information will present a new and robust input for image indexation enhanced methods. In fact, significant extracted terms will be used later to index images in order to facilitate their search through the underlying social network. To overcome the above challenges, we propose an approach which focuses on algorithms mainly based on statistical methods and external semantic resources destined to filter selected extracts information.

Research paper thumbnail of Drug related adverse events due to cardiotropic agents : Epidemiology and prognosis in the emergency department

Toxicity is attributed to their narrow therapeutic spectrum and pharmacodynamic properties. The clinical presentation, however, remains polymorphic and represents a challenge for the emergency physician to relate accountability to the exact agent. AIM To evaluate epidemiological, clinical and prognostic profile of patients visiting emergency department in whom iatrogeny secondary to cardiotropic use was diagnosed. METHODS This was a single-center prospective study over 12 months. We included successively all patients aged over 18 years in whom diagnosis of cardiotropic iatrogeny was made. Cardiotropic related drug-induced events were selected after collegial decision making processing. Prognosis was evaluated in terms of severity and mortality at day 30. Univariate analysis was conducted. P<0.05 was significant. RESULTS We enrolled 51 patients. M...

AIM To assess the prognostic value of the SI ≥ 1 in terms of mortality in severe trauma patients admitted to the emergency room. METHODS We performed a prospective, observational and descriptive study with the inclusion of severe trauma patients over the age of 18 years admitted to the Vital Emergency Room over a 21-month period. SI was calculated at admission: SI = heart rate / systolic blood pressure, a SI threshold value ≥1 was fixed to define two groups: SI<1 and SI≥1. RESULTS A total of 290 trauma patients were included, 231 (79%) had a SI<1, whereas 59 (21%) had an SI≥1. Mean age was 43.5 ± 18 years, 82% were male. There was a significant difference in hospital mortality at 7 days and at 30 days between the two groups respectively (group SI<1 vs group SI≥1): [12% vs 40...
