How many patients could benefit from REBOA in prehospital care? A retrospective study of patients rescued by the doctors of the Paris fire brigade.

INTRODUCTION: Resuscitative endovascular balloon occlusion of the aorta (REBOA) is a technique to control haemorrhage by placing a retrograde catheter in an artery and inflating a balloon at its tip. This retrospective study aimed to evaluate the proportion of injured people who could potentially have benefited from this technique prior to hospitalisation, including on the scene or during transport. METHODS: A retrospective analysis was conducted of all patients with trauma registered in the Paris Fire Brigade emergency medical system between 1 January and 31 December 2014. Inclusion criteria included all patients over 18 years of age with bleeding of supposedly abdominal and/or pelvic and/or junctional origin, uncontrolled haemorrhagic shock or cardiac arrest with attempted resuscitation. RESULTS: During this study period, a total of 1159 patients with trauma (3.2%) would have been eligible to undergo REBOA. Death on scene rate was 83.8% (n=31) and six patients had a beating heart when they arrived at the hospital. Ten out of the 37 patients had spontaneous circulatory activity. Among them, four people died on the scene or during transport. Thirty-six out of 37 patients were intubated, one benefited from the use of a haemostatic dressing and one benefited from a tourniquet. CONCLUSIONS: REBOA can be seen as an effective non-surgical solution to ensure complete haemostasis during the prehospital setting. When comparing the high mortality rate following haemorrhage with the REBOA's rare side effects, the risk-benefit balance is positive. Given that 3% of all patients with trauma based on this study would have been eligible for REBOA, we believe that this intervention should be available in the prehospital setting. The results of this study will be used: educational models for REBOA balloon placement using training manikins, with an ultimate aim to undertake a prospective feasibility study in the prehospital setting.

Contribution of brain CT in the diagnosis of tuberculous meningitis: a case report from Djibouti.

Tuberculous meningitis, a serious disease with high mortality and morbidity, remains frequent in countries with endemic tuberculosis. Its non-specific presentation often delays the introduction of appropriate treatment. Its definitive diagnosis requires isolation of Mycobacterium tuberculosis from cerebrospinal fluid, although this test may be negative without conclusively ruling out this diagnosis. A presumptive diagnosis should be reached as soon as possible through a body of clinical evidence, including the lumbar puncture findings. Brain computed tomography (CT) with and without contrast medium injection is helpful for the diagnosis of tuberculous meningitis and its complications. We discuss the features of CT and their value in relation to a case of tuberculous meningitis in Djibouti, as well as the role of CT in managing this disease.

Medical causes of temporary or definitive leaves from a French counterterrorist unit pre-internship.

INTRODUCTION: Each year, the French Special Weapons And Tactics team, Groupe d'Intervention de la Gendarmerie Nationale, recruits new members through a physically demanding 8-week selection process. The goal of this study is to estimate the incidence and the causes for temporary or final interruptions during this process for medical reasons. SUBJECTS, MATERIAL AND METHODS: All of the candidates for the November 2015 selection process were included in this prospective study. The number and reasons for temporary or final interruptions were documented by military general practitioners. RESULTS: The applicants were 48 law enforcement professionals (2 women, mean age 29.4 years, range 22-35). In 14 cases, a temporary interruption was required and in five cases the selection process prematurely ended. Fifty-two per cent of the temporary interruptions were due to sprains, tendinopathies, fractures or muscle tears, 11% were due to burns, wounds or subcutaneous bruises, 16% were due to cranial trauma and 21% were due to medical causes. DISCUSSION: The high prevalence of minor traumatology that we observed is similar to the ones observed in other cohorts describing initial training for military personnel in the conventional forces. However, the presence of other pathologies in our study, such as cranial trauma or medical causes, is due to the specificity of this internship selection granting access to an elite unit.

[Perstimulus asystole during electroconvulsive therapy: Clinical case and critical literature review]. / Asystolie perstimulus résultant d'une hypertonie parasympathique au cours des électroconvulsivothérapies : cas clinique, brève revue de la littérature et discussion.

INTRODUCTION: Electroconvulsive therapy (ECT) is most frequently indicated for episodes of melancholic depression, but is also useful in the treatment of maniac syndrome and some schizophrenia subtypes. ECT is part of the treatment of movement disorders, neuroleptic malignant syndrome and even in the treatment of severe conversions. Although the therapeutic results are excellent when used appropriately, the mortality rate is estimated between 2 and 4 for 100,000 shocks. Despite this mortality rate, the benefit-risk ratio remains very positive and serious complications are extremely rare. ECT results in a biphasic cardiological effect: firstly a perstimulus parasympathetic hypertonia contemporary to the seizure's tonic phase, then a phase of contemporary sympathetic hypertonia during the epileptic clonic movement. We will focus on the perstimulus asystole as it is by far the most frequent. Very few cases and even less studies have been referenced in the literature; here, we present a clinical case followed by a discussion. CLINICAL CASE: The patient is in his fifties and has been treated for many years for a unipolar mood disorder with recurrent melancholic depressive episodes. With each new depressive episode, the clinical evolution is rapidly positive after a few sessions of ECT. Maintenance ECT was not retained due to the supra-annual periodicity of the melancholic depressive episodes and rapid recovery after electric treatment. Then, this patient developed another depressive decline in mood comparable to the previous one, despite adapted blood lithium levels associated with a new generation antidepressant treatment. According to his history, a hospitalisation was programmed to carry out a new course of ECT. Considering the short duration of the first seizures, the intensity of the stimulus was progressively increased. At 180 joules, the patient presented an immediate per-stimulus asystole of 20seconds which ceased spontaneously. The specialized cardiologic consultation following the rhythmic episode was reassuring: the patient's cardiac condition remained stable. However, after discussion with the patient and his family, we decided to stop the ECT. Was this a reasonable decision? DISCUSSION: According to the literature, the patient's medical history, sex, psychiatric diagnosis, the shock parameters (level of energy applied, duration of the stimulus, number of shocks) and clinical results, are not predictive factors in the occurrence of an asystole. Concerning the ECT protocol, the vagus nerve seems less stimulated during bifrontal stimulations in opposition to unilateral stimulations. Perasystolic patients are younger and have less prior history of cardiovascular disease or ECG abnormalities. Although the patients receiving ECT are often taking several medications (antipsychotics, benzodiazepines, antidepressants, anticholinergic correctors, calcium channel blockers, loop diuretics, converting enzyme inhibitors), these drugs are not considered as facilitating asystoles. No increase in the frequency of asystole had been observed when taking an average dose psychotropic treatment allowing the continuation of an antidepressant treatment at the recommended dose. Differently, lithium is regularly stopped during the shock phase as it could - even a few days after being stopped - potentiate the effects of succinylcholine and increase the vagal tone. Succinylcholine seems to promote asystole, whilst caffeine, methohexital and trimethaphan do not. The hypersympathetic phase can be controlled by a betablocker (propranolol, esmolol, labetalol) that does not increase the prior risk of asystole. Anticholinergic premedication using atropine does not appear to be systematic and could even potentially induce tachy-dysarrhythmia. However, in the case of perstimulus asystole, most authors recommend continuing the shocks with doses of atropine around 0.4 to 1mg. PHYSIOPATHOLOGY: Vagal stimulation is preferentially central and directly linked to the electric excitation of the lateral dorsal motor nucleus of the vagus nerve. Younger patients with no cardiac history are more at risk. This could be explained by the fact that juvenile tissue conducts electricity more rapidly than senescent (the difference being probably due to the fibrosis and adipose tissue which reduce its conductive capacity). Finally, it is appropriate to question the direct therapeutic aspect of vagal stimulation which constitutes an experimental treatment of resistant depression. CONCLUSIONS: The occurrence of perstimulus asystole is not considered as a serious complication of ECT and therefore as a contra-indication to any future sessions. On the contrary, most authors are campaigning for the continuation of shocks with the possibility of adding prophylactic intravenous atropine. Cardiac arrest reminds us that ECT requires a special attention to its cardiovascular effect, which emphasizes the role of interdisciplinarity between anaesthesiologists and psychiatrists.

[Acute pericarditis and tamponade: An unusual revelation of a visceral tuberculosis]. / Péricardite aiguë et prétamponnade: un mode de révélation atypique d'une tuberculose viscérale.

Tuberculosis is a common pulmonary disease, which is still endemic in disadvantaged communities. Pericarditis is a rare but very lethal visceral localization. The authors report the case of a 58-year-old man, without neither medical history nor social risk, who presented a cardiac tamponade as the first and atypic manifestation of a visceral tuberculosis.

[Sudden cardiac death in the youth. Is the new subcutaneous implantable cardioverter defibrillator S-ICD an alternative solution?]. / Mort subite du sujet jeune : le défibrillateur sous-cutané S-ICD est-il une solution alternative aux défibrillateurs conventionnels ?

Implantable cardioverter defibrillator (ICD) is well-recognized therapy to prevent sudden cardiac death. Classic ICD need the use of permanent endocavitary leads, which may cause serious troubles (lead dislodgement, ventricular perforation, lead infections, etc.). The subcutaneous implantable cardioverter defibrillator (S-ICD) is a new device provided by only a subcutaneous lead. It has been developed for the last five years and it is becoming at present a real alternative to classic ICD. We report a clinical case of a 34 y.o. woman who presented a sudden cardiac death and who benefited the implantation of this new technology. This paper deals with the potential indications, usefulness benefits, and problems of the S-ICD.

[Contribution of cardiac MRI in the initial evaluation and follow-up of myocarditis mimicking acute coronary syndrome: a series of 43 patients]. / Apport de l'IRM cardiaque dans l'évaluation initiale et le suivi des myocardites mimant un syndrome coronaire aigu : à propos d'une série de 43 patients.

AIMS: The diagnosis of acute myocarditis is complex, especially when the clinical presentation mimics an acute coronary syndrome. This condition may promote the progression to dilated cardiomyopathy and the occurrence of severe arrhythmias. A reassessment integrating a cardiac MRI at three months after the acute episode could help identify patients with a poor prognosis. PATIENTS AND RESULTS: This prospective series of 43 consecutive patients hospitalised for acute myocarditis included 36 men and seven women, with a mean age of 32 years, with no indication of heart failure. All patients presented elevated levels of troponin I. Echocardiography showed moderate left ventricular dysfunction in six cases and segmental wall motion abnormalities in 22 cases. After gadolinium injection, a subepicardial late enhancement was observed in 39 cases. Three months after the acute episode, all patients were asymptomatic. The echocardiography and laboratory tests were normal. In 23 cases, the MRI showed persistence of the late enhancement without segmental wall motion abnormality. After a mean follow-up of three years, one patient was lost to follow-up and only one suffered a heart failure revealing a dilated cardiomyopathy complicated by ventricular arrhythmias. CONCLUSION: On admission, the subepicardial localisation of late enhancement in the cardiac MRI is reliable criteria for the diagnosis of acute myocarditis, enabling to rule out an acute coronary syndrome. During follow-up, the persistence of late enhancement has no impact on prognosis. In this series, after a mean follow-up of three years, it was not associated with clinical or paraclinical abnormalities, except in one patient.

[Heart failure patterns in Djibouti: epidemiologic transition]. / Insuffisance cardiaque chez l'adulte à Djibouti : la perspective d'une transition épidémiologique.

BACKGROUND: The features of heart failure (HF) in Djibouti have not been well described. We sought to document the current patterns of HF here. METHODS: We prospectively included Djiboutian adults hospitalized for HF in the French Military Hospital (Djibouti) from August 2008 through December 2010. RESULTS: Of 1688 adults hospitalized in the medical department, 45 (2.7%) had symptomatic HF: 38 (84%) men, mean age 55.8 years (range 27-75). Twenty-five (56%) patients were initially hospitalized for acute pulmonary edema. The underlying diseases included coronary artery disease (CAD) (62%), hypertensive heart disease (18%), rheumatic valvular disease (13%), and primary dilated cardiomyopathy (7%). Their cardiovascular risk factors included tobacco use (53%), hypertension (69%), diabetes (47%), and hypercholesterolemia (51%). Patients in the CAD group were older, and had diabetes more often (p<0.01). All khat chewers (53%) were males and smokers. Mean left ventricular ejection fraction (LVEF) was 39 ± 14%. During follow-up (14.4 ± 9 months), 8 (18%) patients died, 9 (20%) were again hospitalized for HF, and 3 (7%) had ischemic strokes. One month after discharge, the New York Heart Association (NYHA) class was II for 40%, III for 44%, and IV for 16%. Higher NYHA classes and dilated cardiomyopathy were both associated with poorer outcomes (p<0.03). CONCLUSION: In hospitalized Djiboutians, most HF patterns are similar to those in industrialized countries. CAD is more prevalent than previously reported in African patients with HF.

[Atypical left ventricular hypertrophy revealing a rare cause of heart failure in a man from the Comoros Islands]. / Hypertrophie ventriculaire gauche atypique révélatrice d'une cause rare d'insuffisance cardiaque chez un Comorien.

In Africa, hypertension is a major public health problem, and hypertensive heart disease is a leading cause of heart failure. Left ventricular hypertrophy is a common consequence of hypertension. We present a case illustrating an unusual cause of such hypertrophy in a 73-year-old patient with heart failure living in the Comoros Islands, in whom we diagnosed cardiac amyloidosis. This disease has not previously been reported in the Comoros Islands and remains associated with a poor prognosis.

[Lipomatous hypertrophy of the interatrial septum]. / Hypertrophie lipomateuse du septum interatrial.

Lipomatous hypertrophy of the heart is a benign rare tumor characterized by fatty tissue deposits in the interatrial septum. Its diagnosis during life is mostly seen incidental. We report the case of a 74-year-old female patient, in which a cardiac mass protruding in the right atrium was diagnosed by transthoracic echocardiography. Transoesophageal echocardiography examination detected an echogenic infiltration and hypertrophy of the interatrial septum, sparing the foramen ovale. The diagnosis of lipomatous hypertrophy of the interatrial septum is confirmed by MRI, which shows a well limited and not encapsulated tumor, appearing in increased signal density on T1-weighted images, and that decreases with fat-saturated sequences. This tumor did not enhance with the administration of contrast material. The benign and lipomatous nature of the lesion is confirmed, thus making the use of histology unnecessary.
