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

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.

Man-O-War simulator: a Low-cost manikin for training on chest tube management.

Simulation-based medical education is becoming a cornerstone in health education. Simulators are commonly expensive and not available in developing countries. We propose a very low-cost simulator that any educator can realize. We describe here the steps to follow to develop this proposed simulator.

Post-traumatic symptoms in patients with acute coronary syndrome: Maybe an outcome predictor after the ED visit!

OBJECTIVES: We aimed to assess the patients' experience of threat during management of an acute coronary syndrome (ACS) in the Emergency Department (ED) and to analyze the impact of this acute stress on day-30 outcomes. STUDY DESIGN: This is a prospective study. METHODS: We included patients with ACS in the ED. After discharge, the perceived stress (Perceived Stress Scale (PSS); Visual Analogic Scale (VAS) in stress evaluation; Patient Health Questionnaire (PHQ); and Posttraumatic Stress Disorder Checklist Scale (PCLS) were used. RESULTS: 35 patients have developed PTSD on day-30 (31.8%). The independent predictors of developing PTSD at day-30 were high PSS score on admission (OR = 1.4; CI = 1.1-1.8; p = 0.004) and/or elevated PHQ-9 score at day-30 (OR = 1.5; CI = 1.2-1.9; p < 0.001). The recurrence of the chest pain was more frequent in the PTSD group of patients. Patients with PTSD symptoms were more likely to report a non-therapeutic adherence to their cardiovascular medication. CONCLUSION: Stress management in EDs should become a systematic step in the management of patients with ACS. This study emphasizes the importance of multidisciplinary follow-up and early screening of patients at risk of PTSD to improve their outcomes after discharge.

Evidence of SARS-CoV-2 symptomatic reinfection in four healthcare professionals from the same hospital despite the presence of antibodies.

OBJECTIVES: Since the onset of the COVID-19 pandemic, cases of reinfection with SARS-CoV-2 have been reported, raising additional public health concerns. SARS-CoV-2 reinfection was assessed in healthcare workers (HCWs) in Tunisia because they are at the greatest exposure to infection by different variants. METHODS: We conducted whole-genome sequencing of the viral RNA from clinical specimens collected during the initial infection and the suspected reinfection from 4 HCWs, who were working at the Habib Bourguiba University Hospital (Sfax, Tunisia) and retested positive for SARS-CoV-2 through reverse transcriptase-polymerase chain reaction (RT-PCR) after recovery from a first infection. A total of 8 viral RNAs from the patients' respiratory specimens were obtained, which allowed us to characterize the differences between viral genomes from initial infection and positive retest. The serology status for total Ig, IgG, and IgM against SARS-CoV-2 was also determined and followed after the first infection. RESULTS: We confirmed through whole-genome sequencing of the viral samples that all 4 cases experienced a reinfection event. The interval between the 2 infection events ranged between 45 and 141 days, and symptoms were milder in the second infection for 2 patients and more severe for the remaining 2 patients. Reinfection occurred in all 4 patients despite the presence of antibodies in 3 of them. CONCLUSION: This study adds to the rapidly growing evidence of COVID-19 reinfection, where viral sequences were used to confirm infection by distinct isolates of SARS-CoV-2 in HCWs. These findings suggest that individuals who are exposed to different SARS-CoV-2 variants might not acquire sufficiently protective immunity through natural infection and emphasize the necessity of their vaccination and the regular follow-up of their immune status both in quantitative and qualitative terms.

Frailty screening of Tunisian older adults: feasibility and usefulness in the Emergency Department.

INTRODUCTION: Frail older adults are at an increased risk for adverse outcomes after an Emergency Department (ED) visit. Several tools exist for the screening of frailty among these patients. However, no tool has been validated in Tunisia. This study aims to evaluate the usefulness of frailty screening in predicting the outcome of older adults presenting to the ED. METHODS: This is a prospective, monocentric study. We evaluated the eligible patients at the ED and after their discharge. Follow-up phone calls were scheduled at 1, 2, 3, and 6 months after the ED visit. All patients aged 65 years or older; and visiting the ED during the inclusion period were involved. We used the ADL index and ISAR scale for assessing frailty. RESULTS: We enrolled 184 patients; they were living alone in 25% of cases. Half of them had medical care insurance. The ADL index was maximum (6 = total dependency) in 20% of cases. The ISAR score was above 1 point in 38%. Unplanned hospitalizations have accounted for 34%. In univariate analysis, the ADL index and ISAR score were statistically higher in the group of "unplanned hospitalization". In multivariate analysis, the ISAR score and ADL index have not been associated with unplanned hospitalization. CONCLUSION: Our results did not demonstrate the relevance of the ISAR or ADL scales in predicting the mortality or the need for unplanned hospitalization in multivariate analysis. This study did indicate an increased mortality in the "frail" patients in the univariate analysis. Further studies with larger samples and different tools are necessary.

Update on the Epidemiology of Scorpion Envenomation in the South of Tunisia.

INTRODUCTION: Scorpion envenomation is still a frequent occurance in tropical and subtropical regions. In Tunisia, multiple studies on scorpion envenoming have contributed to an improved understanding of cardiac dysfunction and factors predictive of poor prognosis. These previous studies have contributed to the current standardized management of envenomed patients. However, the epidemiology of scorpion envenoming in Tunisia has not been updated for more than 10 years. The aim of this study was to report an update of the epidemiological features of scorpion envenomation in the southern region of Tunisia. METHODS: This is a retrospective monocentric study including all patients admitted in the emergency room for scorpion envenomation. Cases were collected from emergency medical files during a 3-year period (2013-2015). The diagnosis of scorpion envenomation was made by history of a scorpion sting. All files in which scorpion envenomation was not certain were excluded. Data are presented as mean±SD with range or percentages, as appropriate. RESULTS: We enrolled 282 patients aged 27.4±22.8 years with a 1:1 sex ratio. During surveillance in the emergency room, 39 patients developed cardiac dysfunction. Overall, 42 patients (14.9%) were at stage 3 of severity, and 240 patients (85.1%) had moderate scorpion envenomation (stage 2). Only 1 patient died a few hours after admission. In the remaining cases, the outcome was good. Our results show the improvement in mortality rates even in severe presentations. CONCLUSION: This study found that the outcome of scorpion-stung patients has clearly improved. This enhancement can be explained by early medical consultation and standardized management of patients with predictive factors for cardiac dysfunction.

[An exceptional cause of peritonitis: ileal perforation due to a foreign body during reduction of an inguinal hernia]. / Une cause exceptionnelle des péritonites: une perforation iléale par un corps étranger lors de la réduction d'une hernie inguinale.

Secondary peritonitis is frequently reported in the literature. It is due to multiple causes. We report an exceptional cause of ileal perforation due to a foreign body during reduction of an inguinal hernia. It caused severe peritonitis with multiple organ failure.
