[Standardized screening of alcohol misuse in emergency wards: The experience of a systematic use of the FACE scale in the European Georges-Pompidou Hospital]. / Repérage standardisé du mésusage de l'alcool au service d'accueil des urgences : l'exemple de la passation systématique du questionnaire FACE à l'hôpital Européen Georges-Pompidou.

INTRODUCTION: By using a standardized and systematic screening with the FACE questionnaire, our aims were : - to determine the prevalence of alcohol misuse (AM) among patients admitted in the emergency department of the European Georges-Pompidou Hospital; - to search for risk factors associated with AM. METHODS: Patients admitted between 9 am and 5 pm were included for 7 consecutive days in June 2017. The variables collected were age, gender, reason for and day of admission, acute alcohol intoxication, benzodiazepines misuse, use of illicit drugs, and the FACE. An AM was defined by a score ≥5 for men and ≥4 for women. Descriptive analyses calculated the prevalence of AM and logistic regressions calculated the risks for AM. RESULTS: A total of 190 men and 221 women were included, with 31% and 19% of them with AM, respectively. The risk of AM was positively associated with male gender, weekend admission and illicit drug use. It was negatively associated with age. The risk of AM was not significantly different according to the reason for admission (trauma versus medical). The risk of AM was not associated with misuse of benzodiazepines. Among the 100 patients with AM, only six had been admitted in acute alcohol intoxication. CONCLUSION: A systematic screening is crucial to identify patients that should benefit from brief intervention or specialized intervention in an addictology unit.

Deliberate drug poisonings admitted to an emergency department in Paris area - a descriptive study and assessment of risk factors for intensive care admission.

OBJECTIVE: Each year, approximately 165,000 poisonings are managed in the emergency departments (ED) in France. We performed a descriptive analysis of self-poisoned patients admitted to a university hospital ED in the Paris metropolitan area (France) aimed at investigating their outcome and the risk factors for transfer to the intensive care unit (ICU). PATIENTS AND METHODS: We retrospectively reviewed patients' records and performed multivariate logistic regression analysis to identify risk factors for ICU admission. RESULTS: During 4 years, 882 self-poisoned patients (median age, 38 years [IQR, 26-47]; sex-ratio, 1M/3F) were admitted to the ED, representing 0.7% of all referred patients. Poisonings mainly resulted from multidrug exposures (53%), including benzodiazepines (78%), serotonin reuptake inhibitors (17%), acetaminophen (13%), antipsychotics (9.5%), imidazopyridines (9.5%), antihypertensive drugs (3%), and polycyclic antidepressants (1.3%). Ethanol was involved in 20% of the exposures. Patients were briefly (<24h) monitored in the ED (55%), transferred to the psychiatric department (30%), medical ward (2%) or ICU (6%), and took an irregular discharge (7%). Among the patients transferred to the ICU, 25% were mechanically ventilated and only one died. Risk factors for ICU admission included antihypertensive (Odds ratio (OR), 40.6; 95%-confidence interval (CI), 7.5-221.9) or antipsychotic drug ingestion (OR, 5.3; CI, 2.0-14.4), male gender (OR, 3.3; CI, 1.30-8.8), and consciousness impairment (OR, 2.1; CI, 1.8-2.5 per point lost in Glasgow coma score). CONCLUSIONS: Deliberate drug exposure represents a frequent cause of ED admission. Psychotropic drugs are most commonly involved. Transfer to the ICU is rare and predicted by male gender, drug class, and coma depth.

[Observatory of the elderly over 80 years supported by the mobile emergency and resuscitation service]. / Observatoire du sujet âgé de plus de 80 ans pris en charge en urgence par le service mobile d'urgence et de réanimation.

Emergency medical services (EMS) received an increasing number of calls for patients aged 80 and older. The goal of the present study was to evaluate outcome and functional dependence of patients aged 80 and older who EMS managed in the prehospital theater. This prospective study was conducted over 1 year (September 2007-August 2008), all consecutive patients aged 80 and older managed by a medical team during the study period were included. Characteristics of patients, including previous health status and functional dependence, were recorded on-the scene by the attending physician. Three-month mortality was recorded, as well as ADL score. Data are expressed as mean values±standard deviations, medians and interquartile ranges (IQRs), and percentages and compared using univariate and multivariate analysis. P<0.05 was considered the threshold for significance. Five hundred twenty-three patients were included. Mean age was 86 ± 5. Median ADL index was 2 (IQR 0-9), and 63% of patients were living at home. At 3 months, the survival rate was 66% (n=273) and the proportion of patients living at home was 64% (P=0.9), the median ADL index of survivors was 2 (IQR 0-8) vs 1 (IQR 0-6) initially for this subpopulation, P=0.01. Our study confirms utility and efficacy of full access of elderly persons to advanced life support especially for self-patients and not restricted based on aging per se. The development and daily use of tools for rapid assessment of autonomy should enable practitioners to innovate and thus, adapt their management.

Gastric residue is not more copious in obese patients.

IMPLICATIONS: Previous studies have shown that obese patients have a larger volume of gastric content than lean patients do. However, methodological limitations call into question the validity of these findings. We have reexamined this issue and found identical gastric content volumes in fasting obese and lean subjects after an 8-h fast.

Effects of riluzole on N-methyl-D-aspartate-induced tyrosine phosphorylation in the rat hippocampus.

Since increased tyrosine phosphorylation has been observed in response to brain ischemia, we investigated whether riluzole (an inhibitor of glutamate neurotransmission with neuroprotective properties) affects tyrosine phosphorylation stimulated by N-methyl-D-aspartate (NMDA) in rat hippocampal slices. Riluzole produced an extremely potent concentration-related inhibition of NMDA (1 mM)-stimulated protein tyrosine phosphorylation (IC(50)=0.5+/-0.03 microM, mean+/-S.D.), but failed to affect that evoked by phorbol 12-myristate 13-acetate (PMA, an activator of protein kinase C, 0.1 and 1 microM). These results suggest that inhibition of tyrosine phosphorylation may contribute to the neuroprotective effects of riluzole against excitotoxic injury.

Postoperative recovery after desflurane, propofol, or isoflurane anesthesia among morbidly obese patients: a prospective, randomized study.

UNLABELLED: Recovery from anesthesia might be compromised in obese patients. Because of its pharmacological properties, desflurane might allow rapid postoperative recovery for these patients. We compared postoperative recovery for 36 obese patients randomized to receive either desflurane, propofol, or isoflurane to maintain anesthesia during laparoscopic gastroplasties. Anesthesia was induced with propofol and succinylcholine IV and was maintained with rocuronium, alfentanil, inhaled nitrous oxide, and the study drug. Immediate recovery (i.e., times from the discontinuation of anesthesia to tracheal extubation, eye opening, and the ability to state one's name) was measured. At the time of postanesthesia care unit (PACU) admission, arterial saturation and the ability of patients to move were recorded. In the PACU, intermediate recovery was measured by using sedation and psychometric evaluations, 30, 60, and 120 min postoperatively. Data were compared between groups by using the Kruskal-Wallis and chi(2) tests. Results were reported as means +/- SD. P: < 0.05, compared with desflurane, was considered significant. Immediate recovery occurred faster, and was more consistent, after desflurane than after propofol or isoflurane (times to extubation were 6 +/- 1 min, 13 +/- 8 min [P: < 0.05, compared with desflurane], and 12 +/- 6 min [P: < 0.05, compared with desflurane], respectively). At PACU admission, SpO(2) values were significantly higher and patient mobility was significantly better after desflurane than after isoflurane or propofol. Sedation was significantly less pronounced with desflurane at 30 and 120 min postoperatively. In morbidly obese patients, postoperative immediate and intermediate recoveries are more rapid after desflurane than after propofol or isoflurane anesthesia. This advantage of desflurane persists at least for 2 h after surgery and is associated with both an improvement in patient mobility and a reduced incidence of postoperative desaturation. IMPLICATIONS: In morbidly obese patients, postoperative immediate and intermediate recoveries are more rapid and consistent after desflurane than after propofol or isoflurane anesthesia.

Postoperative death and malpractice suits: is autopsy useful?

This report demonstrates the extremely high yield of autopsies performed in the case of postoperative death with suspicion of malpractice. They frequently identified undetected complications. They could also suggest faulty or negligent practice that would otherwise go unrecognized. This report supports the widespread use of autopsies to investigate perioperative death.

Halothane stimulates a Na+H+ antiporter involved in the regulation of intracellular pH in alveolar epithelial cells.

UNLABELLED: Changes in intracellular pH (pHi) of alveolar type II (ATII) cells have been involved in the pathophysiology of pulmonary edema. ATII cells have evolved several ions transporters to regulate their pHi, including a Na+H+ antiporter. Because halothane alters the activity of ion transporters in various cells types, it may also affect the activity of this Na+H+ antiporter. This study was performed 1) to characterize a Na+H+ antiporter in a model of ATII cells and 2) to investigate the effect of halothane on the activity of this antiporter. ATII cells were obtained from primary rat ATII cells transfected with a mutant of simian virus SV40 large T antigen (SV40-T2), and their pHi was monitored using the pH-sensitive fluorescent probe 2'-7' (bis carboxyethyl)-5(6')-carboxyfluorescein. We demonstrated in vitro that 1) a Na+H+ antiporter (apparent Km 6.8 +/- 3.4 mM, Vmax 0.0105 +/- 0.0013 delta UpHi/s) regulates the pHi of SV40-T2 cells and 2) at clinically relevant concentrations (10(-3) to 10(-5) M) and for a short exposure duration (60 min), halothane enhances the activity of this antiporter. Because ATII cell acidification has been associated with alterations in the alveolar epithelial barrier, halothane-induced intracellular alkalinization might exhibit some protective effect in clinical situations, such as aspiration pneumonia. IMPLICATIONS: In vitro, halothane induces an intracellular alkalinization of pneumocytes II via the activation of a Na+H+ antiporter. Because acidification of these cells has been associated with alterations in the alveolar epithelial barrier, halothane might exhibit some protective effect in clinical situations, such as aspiration pneumonia.

Post-operative course after conventional or laparoscopic gastroplasty in morbidly obese patients.

The post-operative period is particularly dangerous for obese patients. The aim of this study was to compare the immediate post-operative course after either laparoscopic or open gastroplasty. We studied retrospectively 20 and 14 consecutive patients who underwent laparoscopic or open adjustable silicone gastric banding, respectively. After the laparoscopic procedure, patients had a significantly shorter stay in the post-anaesthesia care unit (0.3 +/- 0.4 and 1.1 +/- 1 days), reduced analgesic requirements, a shorter period of intravenous catheter use (2.3 +/- 1.9 and 4.8 +/- 1.4 days), were able to walk sooner (1 +/- 0.4 and 2.1 +/- 1.6 days) and had a significantly shorter duration of in-hospital stay (5.4 +/- 2.3 and 15.8 +/- 4.5 days) than after an open procedure. This report suggests that the use of laparoscopy for gastroplasty in morbidity obese patients may significantly improve the immediate post-operative course.

Prolonged activity after an ultimately fatal gunshot wound to the heart: case report.

In this article, we describe an unusual case of suicide involving a gunshot wound to the left ventricle. The victim engaged in premortem activity that was both prolonged and methodical. This report stresses the importance of a complete investigation to distinguish such case from an homicide.

[The first death due to inhalation anesthesia in France. An example of the absence of verification of bibliographic references]. / Premiers décès liés à l'anesthésie par inhalation en France. Un exemple d'absence de vérification des références bibliographiques.

The reporting of the first death attributed to anaesthesia is commonly placed in 1848. The present work indicates that, in France, anaesthesia was recognized as being responsible for deaths as early as February, 1847.

Emergence of elderly patients from prolonged desflurane, isoflurane, or propofol anesthesia.

UNLABELLED: Recovery from prolonged anesthesia might be compromised in elderly patients. Desflurane (DES) may be particularly well suited to achieve a rapid postoperative recovery because of its low lipid solubility. Postoperative recovery was compared in 45 elderly patients randomized to receive either DES, isoflurane (ISO), or propofol (PRO) to maintain anesthesia. Anesthesia was induced with PRO, vecuronium, and fentanyl and maintained with N2O, fentanyl, and the study drug. Times from end of anesthesia to tracheal extubation, eye opening and hand squeezing on command, and ability to state name and date of birth were recorded. Sedation and psychometric evaluation were tested 0.5, 1, 1.5, 2, and 24 h postoperatively. Results are given as means +/- SD. Differences among were analyzed by chi2 or analysis of variance. P < 0.05 compared with DES was considered significant. After a prolonged anesthesia (199 +/- 57 min with DES), immediate recovery times were significantly shorter with DES than with ISO or PRO (times to eye opening: 5.6 +/- 3.4 min, 11.5 +/- 8.4 min, and 11.9 +/- 7.6 min; times to extubation: 6.9 +/- 3 min, 13.1 +/- 8.9 min, 9.9 +/- 6.5 min for DES, ISO, and PRO, respectively). Intermediate recovery, as measured by psychometric testing, sedation levels, and time to discharge from the postanesthesia care unit, was similar in the three groups. In this study, DES provided a transient advantage compared with ISO or PRO with respect to early recovery after prolonged general anesthesia in elderly patients. IMPLICATIONS: Recovery from prolonged anesthesia can sometimes be problematic in elderly patients. We evaluated 45 elderly patients who received either desflurane, isoflurane, or propofol for anesthesia. We found that desflurane provided a transient advantage in terms of postoperative recovery, but whether this difference is clinically important remains to be demonstrated.
