Abstract Introduction Telemedicine encompasses all medical practices that allow patients to be remotely cared for through new information and communication technologies. This study aims to assess the remote management of patients consulting emergency services and not requiring in-hospital care during both pre-pandemic and pandemic periods of COVID-19. Methods This was a prospective, randomized, controlled study. The telemedicine group received follow-up at home after emergency room discharge according to a predefined protocol, with telephone calls on days 2, 7, 15, and 30. The control group received standard care without regular telephone follow-up (only a call on day 30). The study was conducted with patients consulting the emergency department of FarhatHached Hospital in Sousse. Patient inclusion occurred between November 1, 2019, and April 30, 2020. The primary outcome measures were the re-consultation rate and treatment adherence. The secondary outcome measure was patient satisfaction.SPSS version 23.0 for Windows was used for data analysis. Descriptive statistics calculated frequencies, percentages, means, standard deviations, medians, and range. Analytical study involved Student’s t-test and Pearson chi-square test for mean and frequency comparisons, respectively. Significance threshold (p) for all tests was set at 0.05. Results A total of 400 patients were included. The average age of patients was 40 years. Both groups were comparable in terms of demographics and clinical characteristics. Diagnoses included mainly benign infectious diseases, trauma, mild decompensations of chronic conditions (asthma, COPD, heart failure), and suspected COVID cases. Patients in the telemedicine group tended to reconsult less in the month following their initial emergency room visit (14% versus 26.5%) (p = 0.004). There was a significant difference in treatment adherence between the telemedicine group and the control group (97.5% versus 92%; p = 0.014). The satisfaction with telemedicine was higher than satisfaction with regard to an in-person consultation at the emergency department (90% versus 37.5%). Conclusion It is necessary to implement telemedicine in Tunisia, especially in emergency services. It ensures better remote patient care by reducing re-consultation rates, increasing treatment adherence, and improving patient satisfaction.

Abstract Background Emergency medicine is particularly well suited to simulation training. However, evidence for the efficacy of simulation-based medical training remains limited especially to manage high-risk cases such as acute asthma. Objective The objective of our study was to compare the performance of high-fidelity simulation (HFS) and interactive video-case challenge-based training (IVC) for final-year medical students in the management of acute asthma. Methods This was a prospective randomized controlled study conducted at the emergency department (ED) of Monastir University hospital ( Tunisia). 69 final-year medical students were randomized to HFS (n = 34) and IVC (n = 35) training on acute asthma topic. The study was conducted over a 1-week period. Efficacy of each teaching method was compared through the use of multiple-choice questionnaires (MCQ) before (pre-test), after (post-test) training and a simulation scenario test conducted 1 week later. The scenario was based on acute asthma management graded on predefined critical actions using two scores: the checklist clinical score (range 0 to 30), and the team skills score (range 0 to 16). Student satisfaction was also evaluated with the Likert 5 points scale. Two years after the post-test, both groups underwent a third MCQ testing to assess sustainability of knowledge. Results There were no differences in age between groups. There was no statistically significant difference between the HFS and IVC groups pre-test scores (p = 0.07). Both groups demonstrated improvement in MCQ post-test from baseline after training session; the HFS MCQ post-test score increased significantly more than the IVC score (p

Abstract Introduction Inferior vena cava (IVC) diameter variability with respiration measured by ultrasound was found to be useful for the diagnosis of heart failure (HF) in ED patients with acute dyspnea. Its value in identifying HF in acute exacerbation of chronic obstructive pulmonary disease exacerbation (AECOPD) was not specifically demonstrated. Objective To determine the value of ΔIVC in the diagnosis of HF patients with AECOPD. Methods This is a prospective study conducted in the ED of three Tunisian university hospitals including patients with AECOPD. During this period, 401 patients met the inclusion criteria. The final diagnosis of HF is based on the opinion of two emergency experts after consulting the data from clinical examination, cardiac echocardiography, and BNP level. The ΔIVC was calculated by two experienced emergency physicians who were blinded from the patient’s clinical and laboratory data. A cut off of 15% was used to define the presence (

Abstract Background Left heart failure (LHF) is commonly associated with acute exacerbation of chronic obstructive pulmonary disease (AECOPD) but its role is often underestimated. Aim of study To evaluate the performance of a new diagnostic technique based on the measurement of the pulse amplitude ratio (PAR) using non-invasive ventilation (NIV) for the early identification LHF in patients admitted to the emergency department (ED) for AECOPD. Results 73 patients were included in this study: 32 in LHF group and 41 in non LHF- group. The two groups had comparable demographic and clinical characteristics at admission. The mean values of PARNIV was significantly higher among LHF patients (0.86 vs. 0.71; p

Abstract Background Little is known about the pattern and appropriateness of antibiotic prescriptions in patients with acute respiratory tract infections (ARTIs). Objective Describe the antibiotics used to treat ARTIs in Tunisian primary care offices and emergency departments (EDs), and assess the appropriateness of their use. Methods It was a prospective multicenter cross-sectional observational clinical study conducted at 63 primary care offices and 6 EDS during a period of 8 months. Appropriateness of antibiotic prescription was evaluated by trained physicians using the medication appropriateness index (MAI). The MAI ratings generated a weighted score of 0 to 18 with higher scores indicating low appropriateness. The study was conducted in accordance with the Declaration of Helsinki and national and institutional standards. The study was approved by the Ethics committee of Monastir Medical Faculty. Results From the 12,880 patients screened we included 9886 patients. The mean age was 47.4, and 55.4% were men. The most frequent diagnosis of ARTI was were acute bronchitis (45.3%), COPD exacerbation (16.3%), tonsillitis (14.6%), rhinopharyngitis (12.2%) and sinusitis (11.5%). The most prescribed classes of antibiotics were penicillins (58.3%), fluoroquinolones (17.6%), and macrolides (16.9%). Antibiotic therapy was inappropriate in 75.5% of patients of whom 65.2% had bronchitis. 65% of patients had one or more antibiotic prescribing inappropriateness criteria as assessed by the MAI. The most frequently rated criteria were with expensiveness (75.8%) and indication (40%). Amoxicillin-clavulanic acid and levofloxacin were the most inappropriately prescribed antibiotics. History of cardiac ischemia ([OR] 3.66; 95% [CI] 2.17–10.26; p 65 years (Odds Ratio [OR] 1.35, 95% confidence interval [CI] 1.16–1.58; p

Abstract Background Chest pain remains one of the most challenging serious complaints in the emergency department (ED). A prompt and accurate risk stratification tool for chest pain patients is paramount to help physcian effectively progrnosticate outcomes. HEART score is considered one of the best scores for chest pain risk stratification. However, most validation studies of HEART score were not performed in populations different from those included in the original one. Objective To validate HEART score as a prognostication tool, among Tunisian ED patients with undifferentiated chest pain. Methods Our prospective, multicenter study enrolled adult patients presenting with chest pain at chest pain units. Patients over 30 years of age with a primary complaint of chest pain were enrolled. HEART score was calculated for every patient. The primary outcome was major cardiovascular events (MACE) occurrence, including all-cause mortality, non-fatal myocardial infarction (MI), and coronary revascularisation over 30 days following the ED visit. The discriminative power of HEART score was evaluated by the area under the ROC curve. A calibration analysis of the HEART score in this population was performed using Hosmer–Lemeshow goodness of test. Results We enrolled 3880 patients (age 56.3; 59.5% males). The application of HEART score showed that most patients were in intermediate risk category (55.3%). Within 30 days of ED visit, MACE were reported in 628 (16.2%) patients, with an incidence of 1.2% in the low risk group, 10.8% in the intermediate risk group and 62.4% in the high risk group. The area under receiver operating characteristic curve was 0.87 (95% CI 0.85–0.88). HEART score was not well calibrated (χ 2 statistic = 12.34; p = 0.03). Conclusion HEART score showed a good discrimination performance in predicting MACE occurrence at 30 days for Tunisian patients with undifferentiated acute chest pain. Heart score was not well calibrated in our population.

Introduction: Duration of antibiotic treatment in acute exacerbation of COPD (AECOPD) is most commonly based on expert opinion. Typical administration periods range from 5 to 7 days. A 2-day course with levofloxacin was not previously assessed. We performed a randomized clinical trial to evaluate the efficacy of 2-day versus 7-day treatment with levofloxacin in patients with AECOPD. Methods and analysis: Patients with AECOPD were randomized to receive levofloxacin for 2 days and 5 days placebo ( n = 155) or levofloxacin for 7 days ( n = 155). All patients received a common dose of intravenous prednisone daily for 5 days. The primary outcome measure was cure rate, and secondary outcomes included need for additional antibiotics, ICU admission rate, re-exacerbation rate, death rate, and exacerbation-free interval (EFI) within 1-year follow-up. The study protocol has been prepared in accordance with the revised Helsinki Declaration for Biomedical Research Involving Human Subjects and Guidelines for Good Clinical Practice. The study was approved by ethics committees of all participating centers prior to implementation (Monastir and Sousse Universities). Results: 310 patients were randomized to receive 2-day course of levofloxacin ( n = 155) or 7-day course ( n = 155). Cure rate was 79.3% ( n = 123) and 74.2% ( n = 115), respectively, in 2-day and 7-day groups [OR 1.3; 95% CI 0.78–2.2 ( p = 0.28)]. Need for additional antibiotics rate was 3.2% and 1.9% in the 2-day group and 7-day group, respectively; ( p = 0.43). ICU admission rate was not significantly different between both groups. One-year re-exacerbation rate was 34.8% ( n = 54) in 2-day group versus 29% ( n = 45) in 7-day group ( p = 0.19); the EFI was 121 days (interquartile range, 99–149) versus 110 days (interquartile range, 89–132) in 2-day and 7-day treatment groups, respectively; ( p = 0.73). One-year death rate was not significantly different between the 2 groups, 5.2% versus 7.1% in the 2-day group and 7-day group, respectively; ( p = 0.26). No difference in adverse effects was detected. Conclusion: Levofloxacin once daily for 2 days is not inferior to 7 days with respect to cure rate, need for additional antibiotics and hospital readmission in AECOPD. Our findings would improve patient compliance and reduce the incidence of bacterial resistance and adverse effects.

Abstract Background Mortality rates and causes of death of the detainees are hence different from those of the general population and there also vary according to regions and countries. Aims To study the peculiarities of death among individuals detained in the region of Sousse in Tunisia and to suggest preventive measures. Material and methods This is a descriptive retrospective study of all deaths in detention collated in the Forensic Medicine department of Farhat Hached teaching hospital in Sousse, Tunisia during a 10-year period 2006 to 2015. Results 26 deaths were collected. All the victims were males. The mean age was 39.5 years. The deaths occurred inside the prison in 42.3% and 57.7% in a hospital. The deaths were of natural causes in 69.2%. The most common natural causes were cancer (6 cases, 33.3%) and infections (5 cases,27.8%). Violent death accounted for 31.8% of deaths with 08 victims. Suicide and homicide were the violent death causes most incriminated each with 11.5% (3 cases). The suicide means was hanging in all cases. The death was accidental in 2 cases (7.7%). Conclusion This study shows that a large proportion of deaths among prisoners are preventable. Prevention is, on the one side, by improving the prison health coverage and on the other side by training the prison staff on the identification of suicidal crises and on controlling the technical devices facilitating the transition to the suicidal act, in particular the hanging cases.

Hydatid pulmonary embolism rarely occurs. It arises from the rupture of a hydatid heart cyst or the opening of a visceral hydatid cyst into the venous circulation. We report a case with pulmonary hydatidosis resulting in a massive bilateral pulmonary embolism in a 56-year-old woman with history of hepatic echinococcosis. A brief overview of clinical features and radiologic findings is presented.

L'insuffisance antéhypophysaire post-traumatique (IAHPT) est une pathologie exceptionnelle mais de réalité certaine résultant des lésions ischémiques lors des traumatismes crâniens (TC) sévères. L'objectif est de préciser à partir d'une étude de cas les critères d'imputabilité de l'IAHPT suite au (TC) ainsi que les spécificités relatifs à sa réparation juridique. C'est une étude médico-légale d'un cas d'IAHPT, diagnostiqué et suivi au service d'endocrinologie et de médecine légale du CHU de Sousse (Tunisie). Il s'agit d'une femme âgée de 45 ans, sans antécédents pathologiques (6 gestes, 4 parités et 2 avortements) ayant un cycle menstruel régulier, sans notion d'accouchement hémorragique, qui a été victime d'un accident de la voie publique (piétonne, heurtée puis renversée par une voiture) occasionnant un TC avec point d'impact occipital sans perte de connaissance initiale; ayant présenté trois ans après l'accident, une hypothyroïdie. L'exploration hormonale rapporte l'atteinte de tous les autres axes. L'exploration neuroradiologique retrouve une intégrité de l'hypophyse et de la tige. Le diagnostic définitif est l'IAHPT. L'expertise médicale (faite 4 ans après l'accident) a conclue à l'imputabilité de l'IAHPT à l'accident. Le taux d'incapacité partielle permanente IIP en droit commun a été évalué à 25%. L'IAHPT est un diagnostic d'élimination. L'évaluation du dommage corporel doit tenir compte des symptômes résiduels, contraintes thérapeutiques et répercussions sur l'activité quotidienne et professionnelle. L'évolution sous hormonothérapie de substitution est souvent favorable, cependant, elle peut être émaillée de complications, d'où l'obligation d'établir des réserves préservant ainsi le droit du patient à une nouvelle révision.
