INTRODUCTION AND IMPORTANCE
Hydatid disease, caused by Echinococcus granulosus, is a zoonotic infection prevalent in specific regions, including Tunisia. Complications are rare but potentially life-threatening. This case report highlights the significance of early diagnosis and intervention in a unique case where anaphylaxis resulted from minor abdominal trauma in a 17-year-old male with an undiagnosed hydatid cyst.
CASE REPORT
The patient arrived at the emergency department with syncope and hypotension after a classroom accident. Physical examination showed an urticarial rash and abdominal tenderness. Anaphylactic shock was diagnosed and promptly treated. A computed tomography scan confirmed a ruptured liver hydatid cyst. The patient received anthelmintic treatment and underwent conservative surgical management. Intraoperatively, a second anaphylactic shock occurred and was promptly treated. The post-operative course was uneventful, and histopathological analysis identified Echinococcus granulosus.
CLINICAL DISCUSSION
This case emphasizes the importance of recognizing hydatid disease as a potential cause of anaphylaxis post-trauma, even in asymptomatic patients. Early diagnosis through imaging is crucial for prompt intervention. Surgical management should be considered, with conservative approaches favored in acute cases. Post-surgical albendazole treatment is essential to prevent recurrence.
CONCLUSION
This report serves as a valuable reference for healthcare professionals, highlighting the need for heightened clinical suspicion in cases like this. It underscores the significance of considering hydatid cyst rupture in the differential diagnosis of anaphylaxis following blunt trauma. Awareness among pediatricians, emergency physicians, and primary care providers can lead to early diagnosis and better patient outcomes, preventing severe complications or fatalities associated with this rare condition.

Cardioneuroablation for vasovagal syncope: insights on patients' selection, centre settings, procedural workflow and endpoints-results from an European Heart Rhythm Association survey.
AIMS
Cardioneuroablation (CNA) is a catheter-based intervention for recurrent vasovagal syncope (VVS) that consists in the modulation of the parasympathetic cardiac autonomic nervous system. This survey aims to provide a comprehensive overview of current CNA utilization in Europe.
METHODS AND RESULTS
A total of 202 participants from 40 different countries replied to the survey. Half of the respondents have performed a CNA during the last 12 months, reflecting that it is considered a treatment option of a subset of patients. Seventy-one per cent of respondents adopt an approach targeting ganglionated plexuses (GPs) systematically in both the right atrium (RA) and left atrium (LA). The second most common strategy (16%) involves LA GP ablation only after no response following RA ablation. The procedural endpoint is frequently an increase in heart rate. Ganglionated plexus localization predominantly relies on an anatomical approach (90%) and electrogram analysis (59%). Less utilized methods include pre-procedural imaging (20%), high-frequency stimulation (17%), and spectral analysis (10%). Post-CNA, anticoagulation or antiplatelet therapy is prescribed, with only 11% of the respondents discharging patients without such medication. Cardioneuroablation is perceived as effective (80% of respondents) and safe (71% estimated <1% rate of procedure-related complications). Half view CNA emerging as a first-line therapy in the near future.
CONCLUSION
This survey offers a snapshot of the current implementation of CNA in Europe. The results show high expectations for the future of CNA, but important heterogeneity exists regarding indications, procedural workflow, and endpoints of CNA. Ongoing efforts are essential to standardize procedural protocols and peri-procedural patient management.

BACKGROUND
Electrocardiographic early repolarization (EER) is linked with idiopathic ventricular fibrillation in adults. It is frequently seen in children, with poorly understood significance. Some evidence suggests that it could be a vagally mediated phenomenon. A retrospective case-control study was undertaken to test the hypothesis that EER is more common among children with typical vasovagal syncope (VVS) than among their peers with nonvagal syncope (NVS) or with no syncope.
METHODS
Patients aged 4-18 years with syncope were identified by a single-centre database search followed by a review of history for features of VVS (n = 150) or NVS (n = 84). The first available electrocardiogram (ECG) for VVS or for NVS was retrieved. Age- and sex-matched children with no known syncope or heart disease were then identified (n = 216). ECGs were assessed separately for EER based on published criteria by 2 observers blinded to patients' clinical status.
RESULTS
Mean age was 12.3 ± 3.2 years, and heart rate was 74.2 ± 16.5 beats/min. EER was more prevalent in VVS (33.3%) than among patients with NVS (19.1%; odds ratio: 2.29; confidence interval: 1.32-5.50) or among those with no syncope (12.5%; odds ratio: 3.14; confidence interval: 1.81-5.46). Heart rates were significantly lower in VVS and NVS (heart rate: 70.1 ± 13.8 and 70.7 ± 12.4 beats/min, respectively) compared with children with no syncope (heart rate: 78.2 ± 18.0 beats/min), both < 0.001.
CONCLUSIONS
EER is more common in paediatric patients with VVS than those with NVS or without syncope, consistent with a possible vagal contribution to the ECG finding.

Arrhythmogenic dysplasia of the right ventricule (ARVC), actually known as arrhythmogenic cardiomyopathy (ACM) is a rare genetic condition caused by the replacement of the normal right ventricular myocardium with fibrofatty tissue. However, 2 other phenotypes affecting the left ventricle were recently discovered. The disease usually appears in patients ranging from 30 to 50 years old; in fact, about 80% of cases occur in young patients <40 years of age. Therefore, it is usually considered in young adults or athletes presenting with a history of syncope, ventricular arrhythmias (VA), and/or sudden cardiac death (SCD). We report an atypical case of a 70-year-old male who was admitted to the hospital for spontaneous ventricular tachycardia (VT) that was reduced by an immediate electric shock, and the paraclinical investigations strongly supported the presence of an almost complete form of the disease with electric signs in favor of possible left ventricular (LV) damage, which makes the case even more interesting.

BACKGROUND AND AIMS
Few studies have evaluated frailty in older hypertensive individuals and the most appropriate tools to identify frailty in this population have yet to be identified. This study compared the performance of six frailty instruments in the prediction of 1-year functional decline in older hypertensive outpatients.
METHODS
The HYPERtension and FRAILty in Older Adults (HYPER-FRAIL) longitudinal pilot study involved hypertensive participants ≥75 years from two geriatric outpatient clinics at Careggi Hospital, Florence, Italy, undergoing identification of frailty with four frailty scales (Fried Frailty Phenotype, Frailty Index [FI], Clinical Frailty Scale [CFS], Frailty Postal Score) and two physical performance tests (Short Physical Performance Battery [SPPB] and gait speed). Prediction of 1-year functional decline (i.e. a ≥ 10-point Barthel Index decrease between baseline and follow-up) was examined based on ROC curve analysis and multivariable logistic regression.
RESULTS
Among 116 participants, 24 % reported functional decline. In the ROC curve analyses, FI (AUC=0.76), CFS (AUC=0.77), gait speed (AUC=0.73) and the SPPB (AUC=0.77) achieved the best predictive performance, with FI ≥0.21 and CFS ≥4 showing the highest sensitivity (82 %) and negative predictive value (91 %). Frailty identified with FI, CFS or physical performance tests was associated with an increased risk of 1-year functional decline, independently of baseline functional status and comorbidity burden.
CONCLUSIONS
FI, CFS and physical performance tests showed similar predictive ability for functional decline in hypertensive outpatients. The CFS and gait speed might be more suitable for clinical use and may be useful to identify non-frail individuals at lower risk of functional decline.

Acute coronary syndrome (ACS) presents significant diagnostic challenges, particularly in cases with atypical presentations and complex clinical scenarios. Here, we describe the case of a 59-year-old man who presented with presyncope, bradycardia, hypotension, and later syncope, attributed to the Bezold-Jarisch reflex. Electrocardiographic findings suggested both inferior and anterior wall infarction, with dynamic changes in T-wave morphology further complicating the diagnostic process. Despite a type A Wellens' pattern indicating critical stenosis in the proximal left anterior descending (LAD) artery, coronary angiography revealed a complete thrombotic lesion in the proximal right coronary artery (RCA), necessitating urgent intervention. Despite the Wellens pattern indicating LAD involvement, RCA revascularization took precedence due to immediate thrombotic risk. This case underscores the diagnostic challenges associated with conflicting clinical manifestations in ACS and highlights the importance of individualized management strategies integrating advanced diagnostic modalities to optimize outcomes. Understanding the interplay of complex clinical presentations and employing a nuanced approach to management are crucial in effectively navigating ACS scenarios.

A 10-year-old female patient experienced syncope while swimming, and electrocardiography revealed polymorphic ventricular tachycardia, leading to a diagnosis of catecholaminergic polymorphic ventricular tachycardia. No pathogenic variant was identified in . Additional comprehensive genetic testing revealed novel compound heterozygous variants in trans-2,3-enoyl-coenzyme A reductase-like gene, which caused a recessive form of catecholaminergic polymorphic ventricular tachycardia.

BACKGROUND
Ictal arrhythmia is a rare condition that causes arrhythmic manifestations induced by epileptic seizures, including asystole or bradycardia. Ictal asystole (IA) is a very rare condition found in patients undergoing video-encephalography (EEG) monitoring. It is often related to temporal lobe epilepsy and can cause syncope, which can lead to injury or even death. . Two patients with epilepsy showed symptoms of syncope. Both patients underwent 4-day ambulatory EEG tests and were diagnosed with IA. Following the tests, the patients were implanted with a permanent pacemaker, and one of them underwent a temporal lobectomy. As a result of these procedures, the patients experienced a reduction in episodes of symptomatic syncope.
CONCLUSION
Patients with ictal asystole and symptomatic ictal bradycardia are at increased risk of falls due to seizures. Although there are no specific guidelines for managing this condition, antiseizure medications, epilepsy surgery, and cardiac pacemaker implantation have been effective treatments.
