[Factors associated with medical residents' brief counseling]. / L'aide au sevrage tabagique : la pratique du conseil minimal par les résidents en médecine.

INTRODUCTION: Smoking is a public health problem. Physicians have an important role in the fight against smoking, particularly by means of the brief advice they can give. The aim of this work was to study the prevalence of brief advice application by medical residents and to identify factors that may condition its practice. METHODS: We conducted a descriptive and analytical study with prospective data collection that included 302 residents practicing in Tunisia who had agreed to respond to an online questionnaire submitted in February and March 2020. RESULTS: Residents' mean age was 28±2 years and the gender ratio was 0.65. Sixty-four percent of them were non-smokers. During their practice, 94% systematically identified their patients' smoking status, but 61.9% were unfamiliar with the concept of brief advice. Residents' brief advice application rate was 57.6%. In multivariate analysis, the factors impacting brief advice application were: gender (OR=0.321, p=0.0001), familiarity with brief counseling (OR=2.808, p=0.002) and having observed brief advice being given by a senior physician (OR=2.328, p=0.0001). CONCLUSION: The rate of brief advice application remains low. On this subject, improved theoretical and practical teaching during medical studies is essential.

Cardiac hydatid cyst in the interventricular septum: A literature review.

Human hydatidosis occurs mainly as a result of infection with the larvae of Echinococcus granulosus. Cardiac echinococcosis is an uncommon disease and the interventricular septum is rarely involved. This article is a review of all of the literature related to hydatid cyst in the interventricular septum included in the PubMed database. Forty-five cases reported between 1964 and 2019 were identified.

Speckle tracking echocardiography in systemic sclerosis: A useful method for detection of myocardial involvement.

BACKGROUND: Systemic sclerosis is a multisystem disorder characterized by tissue fibrosis and organ damage. Heart involvement is one of the main factors shortening survival, which may be underestimated by conventional echocardiography measurements. Two-dimensional speckle-tracking echocardiography is a powerful novel modality to assess subclinical myocardial dysfunction. AIM: The aim of this study is to investigate heart involvement in systemic sclerosis patients, and to determine the usefulness of ventricular longitudinal deformation using the Two-dimensional speckle tracking technology for an early detection of ventricular dysfunction. PATIENTS AND METHODS: Between May 2016 and September 2016, 25 patients with systemic sclerosis and 25 healthy subjects underwent echocardiography to assess heart abnormalities and the strain of the two ventricles using two dimensions' speckle tracking echography. RESULTS: The two groups were comparable in age and gender. Despite comparable left ventricle systolic function (left ventricular ejection fraction patients 64.58±8.87 vs. in healthy 68.2±7.41, P=0.19), patients presented altered longitudinal peak systolic strain values (global longitudinal strain: patients -17.42±1.62 vs. healthy -19.24±8.85, P<0.0001). Despite comparable pulmonary artery systolic pressure, there was a significant alteration in right ventricular systolic and diastolic function assessed by standard measurement. Longitudinal peak systolic strain of the right ventricle was significantly lower in patients compared with controls (P<0.01). CONCLUSION: Ventricular deformation analysis by two dimensions' speckle tracking echocardiography appears to be a sensitive method to detect early ventricular impairment in patients with systemic sclerosis.

[Results of percutaneous mitral balloon commissurotomy in pregnant women about 12 cases]. / Résultats de la dilatation mitrale percutanée chez la femme enceinte à propos de 12 cas.

INTRODUCTION: Mitral stenosis (MS) is the most common valvular heart disease revealed or exacerbated by pregnancy. Percutaneous mitral balloon commissurotomy (PMC) is currently the treatment of choice when mitral valve morphology is favorable. AIM OF THE STUDY: The purpose of this study is to evaluate the immediate, medium and long term results of percutaneous mitral balloon commissurotomy in pregnant women with a severe symptomatic mitral stenosis despite medical treatment. PATIENTS AND METHODS: It is a retrospective study including 12 pregnant patients diagnosed with severe mitral stenosis and hospitalized in the cardiology department of Habib Thameur hospital between 1994 and 2014. A clinical and ultrasonographic monitoring was performed for over 15 years. RESULTS: Mean patients age was 31.5±4.4 years. All patients were in NYHA class III or IV despite medical treatment. Mitral regurgitation was rated as moderate in four cases. Functional improvement was observed in all cases immediately after the procedure. Mitral valve area increased from 1.02±0.5cm2 averaged to 2±0.35cm2. Mitral regurgitation increased in three cases and appeared in two cases. All patients delivered at term. Newborns were all healthy. Two of them had a low birth weight. On the long term follow-up (95.58±64.1 months), five patients had mitral restenosis: two had a surgical valve replacement and three underwent a second percutaneous mitral balloon commissurotomy. CONCLUSION: The effectiveness of the percutaneous mitral balloon commissurotomy is clearly documented by clinical and echocardiographic evaluation. In the case of pregnancy, the goal is not so much to obtain an optimal result but to cause hemodynamic improvement authorizing the continuation of pregnancy and childbirth.

["Smoker's paradox" and reperfusion's strategy in acute myocardial infarction]. / "Paradoxe des fumeurs" et stratégie de reperfusion à la phase aiguë de l'infarctus du myocarde.

UNLABELLED: Previous studies have shown that smokers with acute myocardial infarction (AMI) treated by thrombolysis have lower mortality rates than nonsmokers, a phenomenon often termed "smoker's paradox". This "smoker's paradox" has been rarely studied in case of primary angioplasty. AIM OF THE STUDY: To evaluate the impact of smoking status on the early mortality of patients admitted with AMI with regard to the strategy of reperfusion (intravenous thrombolysis versus primary angioplasty). PATIENTS AND METHODS: Study undertaken from the Monsatir registry of ST elevation MI including 688 patients having had either a hospital or a prehospital thrombolysis (n=397) or a primary angioplasty (n=291). Among those patients, 482 (70.1%) were active smokers. RESULTS: In the thrombolysis group, the prevalence of hypertension, diabetes and anterior location of MI was significantly less among smokers. In the group primary angioplasty, only diabetes and hypertension were less frequent. The immediate mortality was significantly less among smokers in case of thrombolysis comparatively to non-smokers (5.3 vs 13%; p=0.008). By multivariate analysis, cardiogenic shock (p<0.0001), anterior MI (p=0.03) and active smoking (p=0.03) were independent predictive factors of mortality in case of thrombolysis. A trend toward a lower mortality among smokers was observed in the primary angioplasty group (10 vs 17.6%; p=0.07). CONCLUSION: "The smoker's paradox" seems to be observed mainly among patients having had thrombolysis.
