Role of pulmonary ultrasonography in diagnosis of acute heart failure.

BACKGROUND: One of the most prevalent causes of emergency room visits is acute dyspnea. Several etiologies, including cardiac, pulmonary, metabolic, psychogenic etc… may be involved. Acute heart failure (AHF) is among the most common causes. This study aims to evaluate, in patients presenting with acute dyspnea to the emergency departement (ED), the accuracy of a diagnostic approach combining Lung ultrasonography (LUS) and clinical assessment as compared to the traditional AHF diagnostic work-up. METHODS: This is a bi-centric cross-sectional observational study, conducted at the Emergency and Cardiology Department of both the Hedi Chaker Hospital in Sfax and the Habib Thameur Hospital in Tunis for the period extending from 01/07/2022 to 30/09/2023. The diagnostic performance of pulmonary ultrasonography was studied and the sensitivity, specificity, positive predictive value (PPV) and negative predictive value (NPV) were compared with those of clinical examination, chest X-Ray, NT-pro -BNP and the Transthoracic echocardiography (TTE) which was the reference exam. RESULTS: The most common cause of acute dyspnea is acute heart failure (79.3 %). LUS had a sensitivity of 94,2 % in diagnosing AHF and a specificity of 77,5 %. Its PPV and NPV were respectively 92 % and 81 %. The area under curbe (AUC) of B-Lines required for the diagnosis of interstitial pulmonary syndrome was excellent (92 %). There was a moderate significant positive correlation between the number of B-Lines and NT-Pro-BNP levels r = 0.51, P < 0.001. Also, there was a very strong significant positive relationship between the pulmonary congestion assessed by LUS and Left atrium - pressure r = 0.788, P < 0.001 CONCLUSION: LUS is an excellent test both to confirm and exclude the diagnosis of AHF in patients consulting the emergency room for acute dyspnea and therefore deserves to be performed systematically.

[Communication interventriculaire compliquant un infarctus de myocarde antérieur : un cas de fermeture percutanée]. / Ventricular septal defect complicating anterior acute myocardial infarction : A Case of transcatheter closure.

INTRODUCTION: Post-infarction ventricular septal defect (PIVSD) is one of the most serious mechanical complications of acute myocardial infarction (AMI). Over the last decade, percutaneous closure is increasingly undertaken, with results similar to cardiac surgery. We present a case of ST-elevated anterior AMI, complicated by apical PIVSD successfully treated with transcatheter closure. CASE REPORT: An 83-year-old man was hospitalized for chest pain occurred 18 hours before, during the night time. He was an active smoker. Clinical examination revealed normal heart sounds and pulmonary bibasilar crackles. ST-segment elevation with deep T waves inversion in anterior leads were detected on the electrocardiogram. A mildly-reduced ejection fraction (40%) was found by transthoracic echocardiogram. The patient underwent emergency coronary angiography, which revealed a subocclusive stenosis of the mid left anterior descending artery with a TIMI 2 flow, treated by balloon angioplasty and drug-eluting stent. Four days after revascularization, the patient developed an acute deterioration with signs of decompensated heart failure and a new holosystolic murmur with large irradiation. Inotropic agents' administration was required to maintain a precarious hemodynamic condition. A bedside Echo revealed an apical VSD, measuring 15 × 10 mm, with left-to-right shunting, and pulmonary hypertension. The patient was scheduled for transcatheter PIVSD closure. The procedure was performed under fluoroscopic guide. Two vascular access sites were placed, femoral arterial and right internal jugular vein. Through the right internal jugular vein, a 24-mm Amplatzer atrial septal occluder on a 9 French Amplatzer TREVISIO™ intravascular delivery system was advanced via right ventricle into the PIVSD. Contrast fluoroscopy was used to assess apposition and the degree of shunt reduction before release. Echocardiographic evaluation performed 48 hours later confirmed a correct apposition of the device with insignificant residual shunt. At 6 months follow-up, he was asymptomatic, with unchanged prosthetic findings. CONCLUSION: Percutaneous closure has been emerged as a valid cost-effective alternative to surgery and should be advised. However, debate remains on the optimal preprocedural optimization, timing of repair and modality of treatment.

Assessment of debriefing in high-fidelity mannequin simulation: study among students in cardiology.

INTRODUCTION: Debriefing is the fundamental step in the learning process when teaching by simulation. The Debriefing Assessment for Simulation in Healthcare (DASH) guide is a tool designed to assess and develop the debriefing skills of trainers using healthcare simulation. AIM: To evaluate the debriefing in high-fidelity mannequin simulation in the management of cardiological emergency by the DASH tool, student version. METHODS: This was a bicentric, prospective, cross-sectional and evaluative study including five groups of students in the first year of the second cycle of medical studies completing their internship in the cardiology departments of the Habib Thameur hospital and the Internal Security Forces Hospital of Marsa during the first semester of the 2021-2022 academic year. The simulation scenario included the diagnosis and emergency management of degenerative syncopal atrioventricular block. RESULTS: Forty-four students completed the DASH assessment form (28 female, 16 male). According to the students, the trainers had maintained a climate conducive to learning (6.51±0.74). They had conducted the debriefing in a structured way (6.35±0.75). They had aroused engagement in the exchange leading the learner to analyze his performance (6.01±1.03). They had effectively identified the learner's strengths and areas for improvement as well as their reasons (6.39±1.04). The trainers had helped the learners to consider how to improve or maintain a good level of performance (6.57±0.77). The mean DASH score evaluating the trainers was 6.36±0.88. CONCLUSION: The DASH tool allows trainers to highlight the strengths and areas for improvement in the debriefing, which is the key step in the simulation to optimize the clinical reasoning process and improve the quality of care.

Endovascular therapy for steno-occlusive subclavian artery disease early and long-term outcomes in a multicentric Tunisian study.

AIM: To evaluate the outcomes of endovascular therapy in patients with subclavian steno-occlusive disease over the short and long term in a Tunisian population. MATERIALS AND METHODS: Patients who underwent endovascular treatment of subclavian artery (SCA) steno-occlusive disease between 2013 and 2019 in three Tunisian centers were evaluated retrospectively. After treatment, patients were follow-up was scheduled at 1, 3, 6, 12 months postoperatively and annually afterwards by Doppler ultrasound and clinical findings. Primary outcomes included technical, clinical procedural success rates and limb salvage rate. Secondary outcomes included the occurrence of periprocedural complications and primary patency rates. RESULTS: 56 patients (33 males, 58.9%) were evaluated. Patients' mean age was 61.5 + years. Technical success rate was 94.6 %, being 100% in case of stenosis and 78.5% in case of occlusion. The technical success rate was 94.6%. The clinical success rate was 100% and the upper limb salvage rate was 100%. Minor amputations were performed on 5 patients. Perioperative mortality and morbidity rates were 0% and 8.9% respectively. Mean follow-up was 26.7±16.4 months (range 12-86 months). Two in-stent restenosis occurred (at 12 and 15 months) and one case of thrombosis at the 16th month. The primary patency rates were 88.7%+4.3% at the end of the first year and 78.7%+6.1% at 3 years. CONCLUSION: Endovascular treatment can be considered as a safe and effective treatment of SCA steno-occlusive disease, with low perioperative complication rates and a good patency rates over long term. KEY WORDS: Subclavian artery stenosis, Subclavian artery occlusion, endovascular, subclavian revascularization.

Endovascular management of an isolated common iliac artery aneurysm: a case report.

Isolated iliac artery aneurysms are rare, and treatment by conventional surgery gives good results. Endovascular repair of such aneurysms has recently become the preferred form of treatment, provided the appropriate anatomy for endovascular repair exists. We report the case of a 60-year-old man admitted in our department for an aneurysm of the left primitive iliac artery revealed by intermittent claudication and treated by a covered stent after embolization of the hypogastric artery by an Amplatzer Vascular Plug with a good result. This case highlights the importance of preservation of the collaterals of the hypogastric artery when you treat such entity; in order to avoid transient gluteal claudication and sexual dysfunction.

Heart Rate Variability as an Indicator of Autonomic Nervous System Disturbance in Behcet's Disease.

BACKGROUND: Behçet's disease (BD) is a multisystemic vasculiti where cardiac involvement is not common. Previous studies have shown that the incidence of ventricular arrhythmia and sudden cardiac death (SCD) is higher in patients with BD than in the healthy population. Among various possible explanations, autonomic nervous system (ANS) dysfunction has been suggested. Few studies have evaluated ANS function in patients with BD, and the results obtained are controversial. OBJECTIVE: We aimed to assess cardiac autonomic function by heart rate variability (HRV) in patients with BD; to evaluate circadian changes in HRV; and to study the relationship between HRV parameters and disease parameters. METHODS: Thirty-six patients with Behçet's disease (median age 42 years, 28 men) and 36 age- and sex-matched healthy volunteers were included. HRV analyses were performed in the time and frequency domains for the entire 24-hour period and for the daytime and nighttime periods. BD activity was studied with Behcet's disease current activity form (BDCAF). RESULTS: Patients with BD had significantly lower values of SDNN compared to controls. PNN50, RMSSD, and HF components mean values were significantly reduced in patients than in controls implying parasympathetic impairment. LF was comparable between the two groups, whereas LF/HF ratio was significantly higher in BD group. The circadian rhythm of HRV was preserved in patient group. There was no significant correlation of CRP or disease duration with HRV indices in Behçet's subjects. BDCAF score was found to be negatively correlated with LF/HF. CONCLUSION: Patients with BD, despite no cardiovascular involvement, have reduced parasympathetic activity compared with controls. However, circadian rhythms of autonomic function were preserved. As known, there is strong evidence for the role of the ANS in the pathogenesis of ventricular arrhythmias. Thus, being a practical tool, HRV can be an interesting approach for the rhythmic follow-up of BD patients.

Alveolar Hemorrhage Following Thrombolytic Therapy for Acute Myocardial Infarction: Two Case Reports and Literature Review.

Alveolar hemorrhage (AH) is a heterogeneous clinical syndrome with a high mortality rate, characterized by extensive bleeding into the alveolar spaces. AH secondary to systemic thrombolysis treatment in the setting of acute myocardial infarction is an uncommon complication, but potentially fatal and can lead to acute respiratory failure. This entity is rarely reported in the literature. We report two cases of acute AH after intravenous thrombolysis for acute myocardial infarction, which could contribute to the literature on the subject, and discuss the risk factors as well as the clinical and radiological findings supporting the diagnosis. We overview also the rare previous published case reports in this context, and we contrast our findings with those reported in the literature.

Endovascular Management of a Subclavian Arterial Injury During Central Venous Catheter Placement for Hemodialysis.

Subclavian artery injuries after central venous catheter placement constitute a rare but potentially fatal complication. The surgical repair of a subclavian artery trauma is a real challenge, associated with a high rate of morbidity and mortality. The role of endovascular treatment for vascular trauma, including injury to the subclavian artery, continues to evolve. In this manuscript, we report the case of an urgent endovascular repair by a covered stent graft of a subclavian artery perforation following the placement of a central venous catheter for dialysis in a 52-year-old patient, having a chronic kidney failure stage 5, with multiple comorbidities. The present case suggests that attention needs to be paid to preventing iatrogenic arterial cannulation during central vein catheterization to avoid potentially devastating complications. Endovascular treatment using a covered stent should be attempted as a first-line therapeutic option.

Hybrid Management of a Pseudoaneurysm of the Inferior Gluteal Artery Following a Stab Wound.

Aneurysms and pseudoaneurysms of the gluteal artery are rare. They represent less than 1% of the described arterial aneurysms. Those that touch the inferior gluteal artery are even rarer. Only a few cases have been described worldwide. Such cases often present with a variable time course, mode of injury, and associated symptoms, leading to their misdiagnosis and improper treatment. We present the case of a 30-year-old male, who presented to our emergency room one week after a stab wound in the left gluteal region causing a pseudoaneurysm of the left inferior gluteal artery with a sciatic compartment syndrome treated by a hybrid approach.

Both mediastinal and pericardial hydatidosis revealed by ST elevation acute coronary syndrome.

Hydatidosis remains an endemic disease in some regions of the world, such as Tunisia. The liver and the lungs are the most common sites in adults. Mediastinal and pericardial hydatid cysts are very rare even in endemic areas and true incidence has not been described in the literature. We report the case of a 74-year-old woman with clinical, biological and electrocardiographic features of acute myocardial infraction. Two-dimensional echocardiography and detailed imaging revealed a mediastinal and pericardial hydatid cyst. The particularity of the clinical presentation, the complementary investigations as well as the management and follow-up of the patient are discussed. This case is of great interest since the rarity of concomitant hydatid cyst in two uncommon localizations: mediastinum and pericardium, and the unusual incidental discovery during a myocardial infarction.

Prognostic value of atrial strain in non-ischemic dilated cardiomyopathy.

INTRODUCTION: Left atrial function in non-ischemic dilated cardiomyopathy (DCM) has long been underestimated when studying the ultrasound parameters of DCM. Currently, several ultrasound parameters of left atrial function have been proposed as markers to detect patients at risk. AIM: To evaluate the left atriumfunctionwith 2D speckle tracking echocardiography and itsprognostic value in the dilatedcardiomyopathy. METHODS: The study prospectively recruited 40 patients with dilated cardiomyopathy, between January and June 2014, followed up at the cardiology department of Habib Thameur Hospital of Tunis. An echocardiogram was performed for all patients at the beginning of the study. After a 6-month follow-up, the primary endpoint was the occurrence of a major cardiovascular event. The patients were divided into a first group without cardiovascular events (group 1) and a second group with a cardiovascular event (group 2). RESULTS: During the follow-up, 25 patients presented a major cardiovascular event (8 ventricular arrhythmias and 17 hospitalizations for acute decompensated heart failure). There were no significant differences between the two groups regarding cardiovascular risk factors, symptoms and blood testing values.In addition, regarding results obtained from speckle tracking echocardiography, atrial peak-systolic longitudinal strain (PALS) and time to peak atrial longitudinal strain (TPALS) values were observed to be significantly lower in group 2 ( 34.6% in group 1 vs 28.4% in group 2, p=0.000; and 344.6ms in group 1 vs 349.8 ms in group 2, p=0.016 respectively). CONCLUSION: The analysis of the LA speckle tracking in the dilatedcardiomyopathymay help cardiologistto identify patients at high cardiovascular risk and thus improve their management and follow-up.

Serious Game Design with medical students as a Learning Activity for Developing the 4Cs Skills: Communication, Collaboration, Creativity and Critical Thinking: A qualitative research.

INTRODUCTION: The impact of technology in education has led to various changes in the way that different stakeholders, like students and teachers work and interact with each other. The use of the serious game design in educational contexts has been related to the development of the 21st century skills such as communication, collaboration, creativity and critical thinking. AIM: To analyze a serious game design process by third -year medical students, from the perspective of the 21st century competencies engaged in the game design process. Those outlined key competencies are communication, collaboration, creativity and critical thinking. METHODS: This is a qualitative, descriptive, and inductive study that follows a phenomenological approach. Twelve volunteer third-year medical students participated in an activity of designing of serious games. This study, carried out during summer internship in the cardiology department of Habib Thameur Hospital. The course of the designing of serious games with students spread over 4 weeks with 10 hours face-to-face and 10 hours of remote work. RESULTS: The participants in our study were twelves third-year medical students. Of these 12 students, 10 were female. The duration of each interview depends on each participant's ability. The analysis of the data, based on the phenomenological method of Giorgi brought out four central themes: theme 1: Critical thinking skills and problems solving skills, theme 2: Communication, theme 3: Creativity, theme 4: Collaboration. The overall essence of the phenomenon is these third medical students who experienced the serious game design outlined key competencies. CONCLUSION: Using serious game development-based learning as a learning method to impart multidimensional skills and knowledge suggests a promising approach for developing clinical reasoning, creativity, communication, and collaboration in students.

Effects of Ramadan fasting on blood pressure in hypertensive patients.

INTRODUCTION: During Ramadan, repeated cycles of fasting might contribute to changes in blood pressure among hypertensive patients. Studies on the effects of fasting on the blood pressure of hypertensive patients are scarce and have provided inconclusive results. AIM: To examine the effect of fasting on ambulatory blood pressure and heart rate in treated hypertensive subjects. METHODS: The study prospectively recruited 60 hypertensive patients between April and June 2019, followed up at the cardiology department of Habib Thameur Hospital of Tunis. A 24-hour pressure monitoring was carried out during two periods: prior to Ramadan and during the last ten days of Ramadan. We compared the average values of 24 hour, awake and asleep systolic and diastolic blood pressure and 24 hour, awake and asleep heart rate. RESULTS: We studied 40 women and 20 men; mean age was 58.4 years. 33% of the patients were diabetics, 42% dyslipidemics, 15% had coronaropathy. 45% of the patients were on monotherapy, 37% on dual therapy and 18% on a triple antihypertensive therapy. During Ramadan, 74% of the patients were taking the treatment once daily, 3% twice daily, and 23% three times per day. Average 24hour ambulatory blood pressure in the whole group was 129±17/74±10 mmHg before Ramadan and 128±17/73±9 mmHg during Ramadan (p>0.05). Daytime and nighttime mean values of systolic and diastolic blood pressure as well as mean values of heart rate were not different between both periods regardless of age, gender, medical history and lifestyle. CONCLUSIONS: In this study, there were no significant changes in systolic and diastolic blood pressures as well as heart rate during the 2 periods.

Assessing medical student satisfaction and interest with serious game.

INTRODUCTION: Serious games are interactive and entertaining digital software with an educational purpose, and they are increasingly being used in undergraduate medical education. Effective serious games attempt to form positive mood in order to encourage players to continue the play, leading to increased interest in gameplay and satisfaction as well as better academic performances. AIM: To determine  the medical students' satisfaction, situational and individual interest during a serious game. METHODS: This was a prospective study performed during a 2-year period (2018-2019 and 2019-2020). A total of 108 third-year medical students participated in this study. Students were asked to play a serious game on a computer for 20 minutes. A set of questionnaires containing evaluation grids to measure the satisfaction and interest was given to students. The effectiveness of the game was assessed using pre and post-tests. RESULTS: Following the exclusion criteria of students due to missing data, complete data were available for 97 students. Satisfaction and interest experienced by the students were high. The median of the game performance of students was 418, 04 points. There was a positive relationship between ease of use and game performance. There was a negative correlation between the three scales of interest and game performance. There was a significant difference between the mean scores of pre-tests and post-tests (p<0.01). CONCLUSION: The results of this study suggest the potentials of serious game on medical student's satisfaction, interest and learning achievement.

The value of simulation in learning clinical reasoning.

BACKGROUND: Simulation allows learning in action, reflection and feedback. All these factors suggest the positive contribution of the simulation to the development of clinical reasoning. The main assessment tool for standardized testing of this skill is the script matching test. AIM: To assess the impact of teaching through high-fidelity clinical simulation on the clinical reasoning of third-year medical students, while assessing their teaching practices, satisfaction and confidence in the learning they received during this session. METHODS: We conducted an evaluative bicentric prospective study that included third-year medical students completing their cardiology internship during the first semester of the academic year 2019-2020 in the cardiology departments of Habib Thameur Hospital and Charles Nicolle Hospital, respectively. RESULTS: The study included 48 students. The students who participated in this study liked the teaching practices used in the simulation-assisted lessons. Their interest in these practices is validated by the average of 37,2±5,53 obtained for active learning, 8,04±1,85 for collaboration, 8,5±1,51 for diversity of styles and 8,02±1,72 for high expectations. In our study, the results showed that students were satisfied with the learning they had made during the simulation session. The average for the measurement of satisfaction by the 48 externals was 22,37±2,54. The results of our study indicated that students were confident that their learning would allow them to solve problems similar to those presented in the simulation in a real clinical setting. This is supported by the 31,48±4,63 average student confidence in their learning. Our study showed a progression of the students' clinical reasoning with simulation using a Script Concordance Test. The mark obtained by the students after the simulation session is significantly higher than the one obtained by the students before the simulation session with p=0.008. CONCLUSION: Simulation is an innovative pedagogical strategy and a contribution to optimizing the clinical reasoning process and improving the quality of care.

Evaluation of students' motivation during the gamification of electrocardiogram interpretation learning.

INTRODUCTION: The quality of the training of medical students is one of the guarantors of the proper functioning of our health system. Gamification is an innovative educational pedagogical method that stimulates the pleasure of learning and encourages learner motivation. AIM: To evaluate the subjective and external motivations and academic self-efficacy of DCEM1 students by playing with TD sessions designed to learn the systematic interpretation of rhythm disorders on surface ECGs using playing cards. METHODS: It was a descriptive, cross-sectional study. Three successive groups of 25 students each took part in this study which took place at the Faculty of Medicine of Tunis. Each group was subdivided into 5 subgroups. During the TD session, the same 18 playing cards are distributed to each subgroup, and various wide and thin QRS tachycardia ECG plots are projected successively. Each subgroup should collect playing cards related to the methodical interpretation of each ECG trace and establish the final diagnosis of rhythm disorder. At the end of the pedagogical training, an anonymous self-assessment questionnaire to measure the types of motivation and academic self-efficacy was submitted to the students. RESULTS: Seventy-five students participated in our study. They were mostly female (sex ratio = 4). Gamification learning using playing cards has generated learners' intrinsic motivation (5.89 ± 0.97), allowing them to feel more confident in themselves, capable of acquiring new skills. Regarding extrinsic motivation, having good results on the exam was not their main concern (4.34 ± 1.23). This learning method has created a feeling of self-efficacy among our learners (5,004 ± 0,98). Indeed, they proved to be able to assimilate the fundamental notions of the course (5.86 ± 1.26), to understand the most complex material of the course (5 ± 1.55) and to acquire the competences targeted by this course (5.41 ± 0.5 ). Finally, all learners were satisfied with the method of gamification learning using playing cards. They recommended that this method be generalized throughout all ECG sessions. CONCLUSION: Gamification learning seems to be an effective and appropriate approach to teaching in the medical field since it allows to associate the notion of pleasure and the act of learning and stimulating motivation and self-efficacy learners.

Prognostic value of ST2 in myocardial infarction.

INTRODUCTION: Soluble Suppression of Tumorigenicity 2 (ST2) is a biomarker of myocardial fibrosis increasingly recognized as a predictor of morbidity and mortality in heart failure. Its role in the prognosis after a myocardial infarction has not been validated to date. AIM: To evaluate the prognostic value of ST2 for in-hospital morbidity and mortality after myocardial infarction. METHODS: We conducted a longitudinal prospective study including 74 patients admitted for an acute uncomplicated cardiac myocardial infarction at Habib Thameur hospital between April and October 2016. ST2 blood samples were drawn until 72 hours post admission .The primary endpoint was the occurrence of a major cardiovascular event during hospitalization. RESULTS: Patients' mean age was 61.28 ± 13 years-old with a sex ratio of 1.8. The reason for admission was acute coronary syndrome with persistent ST segment elevation in 54% of cases and non-ST segment elevation acute myocardial infarction in 46% of cases. The ST2 assay was positive in 78% of cases with a mean value of 122.43 ± 95.72 ng/ ml. Left ventricular dysfunction was observed in 47% of cases. Fifteen per cent of the patients had a 3 vessel-disease, 24% a 2 vessel-disease and 34% a 1 vessel-disease. Twenty-six percent had at least one major cardiovascular event. In-hospital mortality was 10%. In multivariate analysis, ST2 was an independent factor associated with the occurrence of major cardiovascular events (RR = 2, p = 0.04). The cutoff value of ST2 of 35 ng/ml had a sensitivity of 95%, a specificity of 30% (AUC = 0.672, CI 0.546-0.798, p = 0.024), a negative predictive value of 100% and a positive value of 33%. A significant correlation was found between ST2 and troponin, blood glucose on admission, CRP and left ventricular ejection fraction (respectively: r = 0.398, p <0.0001, r = 0.281, p = 0.015, r = 0.245, p = 0.039, r = -0.401, p <0.0001). CONCLUSION: The measurement of ST2 after a myocardial infarction constitutes a new prognostic indicator of in-hospital morbidity and mortality.

Impairment of left and right ventricular longitudinal strain in asymptomatic children with type 1 diabetes.

AIM: The relationship between type 1 diabetes (T1DM) and cardiac function in children is not well established. The purpose of this study was to investigate whether children and adolescents with T1DM present early asymptomatic abnormalities of left ventricular (LV) and right ventricular (RV) function. In addition, we evaluated the relationship of any such abnormalities with glycemic control and diabetes duration. METHODS: This was a prospective study. Standard echocardiography, tissue Doppler imaging, and two-dimensional strain analysis were performed prospectively in 52 children with T1DM. The results were compared with those from 52 healthy children matched for age and sex. RESULTS: There were no significant differences between the two groups in LV ejection fraction or RV systolic function. There was a difference between the two study groups in transtricuspid flow: the E-wave and A-wave velocities were significantly higher in the diabetic group. Left ventricular global longitudinal strain (LV GLS) was significantly lower in children with T1DM (-20.01 ± 1.86% vs. -22.99 ± 0.98%, respectively; P < .001), as was RV free-wall longitudinal strain (RV FWLS) (-29.13 ± 1.85% vs. -30.22 ± 1.53%, respectively; P = .002). LV GLS was correlated with diabetes duration (r = 0.444, P < .001) and glycated hemoglobin (HbA1c) (r = 0.683, P < .001); however, no correlation was found between RV FWLS and HbA1c or diabetes duration. CONCLUSIONS: Our findings suggest that LV GLS and RV FWLS are impaired in children with T1DM and that the decrease in LV GLS is correlated with diabetes duration and HbA1c levels.

Script concordance test as a sanctionnal evaluation in cardiology.

INTRODUCTION: Sanctioning evaluation in cardiology is carried out using multiple choice questions, short-answer questions, clinical cases and editorial questions. However, these methods do not assess clinical reasoning in a context of uncertainty in contrast with script concordance tests (SCT). AIM: To compare the scores obtained by the students in the 3rd year of medicine with the SCT versus the sanctioning test of cardiology and to study the correlation between these two evaluation methods. METHODS: This is a prospective study including 31 3rd year students who completed their cardiology clerckship in the Cardiology Department of the HabibThameur Hospital during the first half of 2016. We compared the scores obtained in the 13 SCT test (39 items) with those of the cardiology normative test. RESULTS: Students 'mean score at SCT was significantly lower than that of experts (66.6 ± 10.2 vs 86 ± 6.7%, p <0.0001). The mean score obtained by students at the SCT was significantly higher than that of the cardiology sanctioning test (p <0.001). Cronbach alpha coefficient was 0.71. There was no correlation between the two tests (r = 0.329; p= 0.07). CONCLUSION: The evaluation of our students by the SCT showed mean score statistically higher than the questions of a classic test, without correlation between them. This should encourage us to incorporate SCT into our assessment methods to promote clinical reasoning.

Factors associated with poor medication compliance in hypertensive patients.

INTRODUCTION: Hypertension is a major cause of cardiovascular morbidity and mortality. Despite therapeutic advances, only one-third of patients achieve blood pressure targets. Poor compliance is one of the main causes. AIM: To study the factors associated with poor compliance in hypertensive patients. METHODS: We conducted a descriptive prospective study including 200 hypertensive patients treated and followed out between March and April 2017. The Girerd medication adherence questionnaire was submitted to patients during an semi-directed interview. RESULTS: Patients meanagewas of 63.28 ± 9.62 years-old and sex ratio of 0.92. The predominant risk factor was dyslipidemia in 45% of cases, followed by smoking 36.5% and diabetes 25.5%. A previous history of acute coronary syndrome was found in 33.5% of cases and atrial fibrillation in 13%. Fifteen percent of our patients consumed alcohol regularly and 9.5% practiced regular physical activity. Fifty-five percent of our patients were on low sodium diet. The prevalence of poor medication adherence was 20.5%. In multivariate analysis, independent factors related to poor medication adherence were: the number of treating specialist physicians greater than 1 (OR = 3.444, p = 0.008) and the absence of information received on hypertension (OR = 4.345; p= 0.003). CONCLUSION: The improvement of medication adherence for our patients must be based on information on hypertension and its risks and the harmonization of care between treating physicians.
