Abstract

Context: Cardiac dysfunction is one of the most serious consequences of scorpion envenomation. The best tool to evaluate cardiac function is echocardiography, but it is not available at all emergency departments. Many studies aimed to describe biological predictive factors of cardiac dysfunction in scorpion envenomation. Troponin is one of these biomarkers but its correlation with myocarditis is not well established. The aim of this study was to evaluate correlation between troponin levels and cardiac dysfunction in moderate scorpion envenomation. Methods: A retrospective monocentric study including patients admitted in the emergency department for moderate scorpion envenomation with troponin measurement during their early management. On arrival, an electrocardiogram and a chest X-ray were realized for all patients. Results: We enrolled 132 patients with a mean age at 31.3 + 24.4 years and a 1.35 sex-ratio. All patients had moderate systemic manifestations. There were 28 patients with clinical manifestations of cardiac dysfunction without life-threatening troubles (21.2%). Troponin was undetectable in 69 patients (56%). The mean value of troponin level (pg/ml) was higher in patients with clinical manifestations of left ventricular dysfunction (1.80+3.8 vs. 0.11+0.5; p = 0.02). Troponin levels were significantly higher in patients with positive T wave on electrocardiogram. Conclusion: In patients with moderate scorpion envenomation with positive T wave, high values of troponin suggest the presence of cardiac dysfunction. [ABSTRACT FROM AUTHOR]

47. Quelles sont les particularités épidémio-cliniques et évolutives des hospitalisations pour anthropozoonoses dans le Sud-Tunisien ?

Author

Baklouti, M., Ayed, H. Ben, Ketata, N., Maamri, H., Yaich, S., Karray, R., Jdidi, J., Kassis, M., Feki, H., and Damak, J.

Abstract

Les anthropozoonoses sont des infections qui se transmettent naturellement des animaux à l'être humain. Ces hémizoonoses peuvent être virales, bactériennes, parasitaires ou mycosiques. La gravité de ces maladies est très variable, pouvant aller d'une simple réaction locale à une affection mortelle. L'objectif de notre étude était de décrire le profil épidémio-clinique des hospitalisations pour anthropozoonoses et d’étudier leurs tendances chronologiques au fils des années.

Abstract

Introduction: Electrical injuries (EIs) represent a significant clinical challenge due to their complex pathophysiology and variable presentation, ranging from minor burns to severe internal organ damage. Despite their prevalence in both; domestic and occupational settings, there remains a rareness of systematic guidelines and comprehensive literature to aid clinicians in effectively managing these injuries. Understanding these factors is crucial for developing protocols that can mitigate the risk of delayed complications, such as cardiac arrhythmias, in patients who initially appear stable., Objectives: This study aims to elucidate the epidemiology, clinical outcomes, and predictors of severe presentation in EIs, providing insights to improve patient assessment and management strategies., Methods: A retrospective study was conducted over 4 years. Data were collected from standardized medical records. The group of patients with severe complications included those who presented a life-threatening cardiac, respiratory, neurological, or biological impairment or died within the first 48 h of the EI., Results: We enrolled 118 cases of electrical injury (EI). Ages ranged from 4 to 82 years, with 31.3% under 15. EI incidence peaked in summer, with 63.5% being home accidents. High-voltage injuries occurred in 13.6%. The most common ED complaints were burns in children (59.5%) and trauma in adults (48.1%). ECG abnormalities correlated with tetany (p = 0.016), and palpitations (p = 0.014). Complications included cardiac arrest (n = 8), rhabdomyolysis (n = 23), and acute renal injury (n = 9). Severe EI was linked to respiratory distress and creatine kinase levels higher than ≥ 253 UI/l. A normal ECG within 1 h post-injury was correlated to a low risk of severe EI. At 2-year follow-up, 43.9% of survivors reported aesthetic sequelae, 25.3% had psychological disorders, and 7% of adults could not return to their previous occupations., Conclusion: EIs are frequent, with diverse clinical presentations requiring multidisciplinary care. Awareness of potential delayed complications is essential, and prevention is crucial., Competing Interests: Declarations. Conflict of interest: The authors declare no competing interests., (© 2025.

Abstract

Background: The COVID-19 pandemic continues to spread throughout the world causing serious morbidity and mortality. Health care professionals (HCP) are on the front line in the face of this pandemic and are identified as priorities for COVID-19 vaccination. This study aimed to estimate the acceptability rate of the COVID-19 vaccination among HCP and to identify their predisposing factors. Methods: This was a cross-sectional study using an anonymous self-administered questionnaire including a randomized sample of HCP in Southern Tunisia, on March-April 2021. Results: Among 300 participants, the COVID-19 vaccine acceptability rate was 65.3%. Factors independently associated with vaccine acceptability were age groups <30 years [Adjusted Odds Ratio (AOR)=4.36; p  = 0.002)], urbanity of residence (AOR = 3.44; p  = 0.027), medical professional category (AOR = 2.69; p  = 0.023) and caring for coronavirus infected patients (AOR = 2.32; p  = 0.047). Belief that COVID-19 vaccination is important to work safely as a health care provider (AOR = 3.26; p  = 0.013), should be available for all HCP (AOR = 17.98; p  = 0.004) and has been quickly developed before it has been thoroughly vetted and tested for efficacy and safety (AOR = 5.88; p  < 0.01) were independently associated with willingness to accept vaccine. Planning to get a COVID-19 vaccine for the next years and recommending it to the family were independent predictive factors of accepting COVID-19 vaccine ((AOR = 6.88; p  < 0.001) and (AOR = 25.03; p  < 0.001), respectively). Conclusion: The acceptance rate of vaccination against COVID-19 among Tunisian HCP is still low in South Tunisian hospitals. Socio-demographic, cultural and professional factors predisposing to the vaccination willingness were highlighted. Combating the vaccine hesitancy of HCP through enhancing sensibilization campaigns is essential to promote vaccination in general population.

50. Catheterized chicken for training on ultrasound-guided vascular access: A simple, cost-effective, and effective model.

Author

Abstract

Ultrasound-guided vascular access is a medical procedure that is becoming increasingly common in daily practice and is recommended to avoid iatrogenic complications. One of the procedures with a high-risk rate of complications is the vascular puncture. However, training on this technique can be challenging due to the limited availability of simulation models. We propose a simple, cost-effective, and effective ultrasound-guided vascular access simulation model that utilizes chicken breast and a urine catheter to address this need., Competing Interests: The authors declare no conflicts of interest., (© 2024 The Authors.
