[Analysis of the accuracy of a coronary syndrome register].

Registers of the management of infarction can complement information obtained from randomised trials evaluating the methods and practice of treatment. In order to do this, the quality of the registers must be assured, and in particular the accuracy of the recorded cases. The objective of this study was to evaluate the accuracy of a register for the in-hospital and pre-hospital management of acute coronary syndromes with ST segment elevation of less than 12 hours' duration. Using a capture-recapture method, the study compared cases in the register with eligible cases present in the hospital and emergency ambulance service databases at two establishments, giving a recruitment rate of 61%. The rate of accuracy was estimated at 84% (95% CI [82 ; 86]). The independent factors associated with failure of notification were female sex (ORa=6.65 [2.04-21.69]), presentation at nights, weekends or bank holidays (ORa=4.13 [1.33-12.85]), direct admission to hospital without passing by the emergency ambulance service (ORa=2.85 [1.03-7.69]), primary angioplasty (ORa=6.18 [1.60-23.79]) and the absence of reperfusion (ORa=40.38 [6.21-262.40]). With more than 80% accuracy, the results produced by the register are robust. The selection bias linked to the under-representation of certain subgroups, while real, has only a marginal impact on estimates derived from the register. Factors associated with failure of notification should be taken into account when operating such a register.

Are there good and bad responders to prehospital thrombolysis in the acute phase of myocardial infarction? OPTIMAL study rationale.

The effectiveness of thrombolytics has been clearly demonstrated in more than half the cases in the large cohorts of patients selected for trials during the acute phase of myocardial infarction. At individual level, thrombolysis will clinically either succeed or fail so, for the medical team managing the patient, choice of treatment may be likened to a gamble which in the best of cases (most often) leads to an uncomplicated success and, in the worst of cases, failure worsened by a severe complication. OPTIMAL is a multidisciplinary and multicentre, prospective cohort study associating mobile medical teams and interventional cardiology units to test the hypothesis that the outcome of prehospital thrombolysis does not depend on chance alone but also varies according to demographic, etiological, clinical and logistic factors involved in the occurrence and management of myocardial infarction. The primary objective of this French study, conducted over one year on more than 800 subjects, is to identify the predictors of the results of prehospital thrombolysis from a very early angiographic evaluation. The results for this cohort may be useful for setting up appropriate management strategies for acute myocardial infarction, from the prehospital phase (thrombolysis or not) up to in-hospital orientation of the patients (angiography room or Intensive Care Unit) and to determine the most judicious time for coronary angiography. OPTIMAL is to date the largest prospective serie of prehospital thrombolysis evaluated by an early angiographic control.

[Fatal outcome of an hydrogen sulfide poisoning].

We report a case of fatal outcome poisoning by massive exposure to hydrogen sulfide of a sewer worker. This rare event was associated with a moderate intoxication of two members of the rescue team. The death was due to asystole and massive lung oedema. Autopsy analysis showed diffuse necrotic lesions in lungs. Hydrogen sulfide is a direct and systemic poison, produced by organic matter decomposition. The direct toxicity mechanism is still unclear. The systemic toxicity is due to an acute toxicity by oxygen depletion at cellular level. It is highly diffusable and potentially very dangerous. At low concentration, rotten egg smell must trigger hydrogen sulfide suspicion since at higher concentration it is undetectable, making intoxication possible. In case of acute intoxication, there is an almost instantaneous cardiovascular failure and a rapid death. Hydrogen sulfide exposure requires prevention measures and more specifically the use of respiratory equipment for members of the rescue team.

Is ECG-guidance a helpful method to correctly position a central venous catheter during prehospital emergency care?

BACKGROUND: Insertion of a central venous catheter (CVC) in an emergency situation is challenging and may be potentially associated with more complications. Because CVC positioning by ECG-guidance may help to decrease the frequency of a malpositioned catheter, we decided to prospectively evaluate the usefulness of positioning a CVC by ECG-guidance during prehospital emergency care. METHODS: Prospective observational study during which all patients requiring CVC placement during prehospital care were included. We compared two periods of 1 year during which CVCs were inserted without and then with the help of ECG-guidance. RESULTS: Eighty successive patients were included. We observed a significant reduction of incorrectly positioned CVCs with ECG-guidance (13% vs. 38%, P < 0.05) and a decreased number of chest X-rays needed to verify the position of the CVC (40 vs. 54, P < 0.05). CONCLUSION: ECG-guidance is a safe and feasible technique which significantly improved the rate of CVCs correctly positioned during prehospital emergency care.

[Ectopic pregnancy: criteria to decide between medical and conservative surgical treatment?].

OBJECTIVE: To search for criteria which should be used to decide between medical treatment and conservative laparoscopic treatment of ectopic pregnancy. METHOD: A Medline search was conducted via Pubmed and in the Cochrane Library. Other studies were selected from the references used in recent randomized trials. RESULTS: Results of medical and of conservative laparoscopic treatment have been similar in patients selected for prospective randomized trials. The criteria used to include patients in these studies were determined arbitrarily. Two scores were evaluated prospectively, they included criteria which may be difficult to use in clinical practice. CONCLUSION: The treatment should performed surgically if the patient is hemodynamically unstable, ss-hCG is >10,000 mUI/mL, the ectopic pregnancy is > or =4 cm in diameter, if there is a medical contraindication to methotrexate, and if the patient may not be followed adequately after treatment. Medical treatment should be preferred if the patient has undergone surgery many times previously, has extensive pelvic adhesion, a contraindication for general anesthesia, a cornual pregnancy, and after failure of a conservative laparoscopic treatment. Medical treatment is possible: if ss-hCG is below 5,000 or 10,000 mUI/mL, if the ectopic pregnancy is less than 4 cm in diameter or if the score is adequate when a scoring system prospectively evaluated can be used. Medical treatment should be preferred: if ss-hCG<1000 mUI/mL, if the patient has no pain and if the ectopic pregnancy cannot be visualized at ultrasound.

[Intrauterine growth retardation associated with a mosaic trisomy 20 limited to the placenta. A case report].

When an amniocentesis was performed to determine fetal age, the karyotype was found to be a trisomy-20 mosaic, which could not be confirmed at birth on peripheral blood but which was confirmed at the cytogenetic examination of the placenta. Fetal growth impairment occurred. Mosaic trisomy in the placenta alone is known to affect fetal development. Normally, lethal, mosaic trisomy found during antenatal diagnosis in a viable fetus with no detectable malformation suggests an extra-embryo anomaly. The risk of spontaneous abortion and fetal growth retardation is however increased making strict echographic surveillance essential in these pregnancies.
