Ectopic Atrial Tachycardia in a 12-Month-Old Girl Treated With Ivabradine and Beta-Blocker, a Case Report

We report on a 12-month-old girl with an ectopic atrial tachycardia successfully treated with the combination of a beta blocking agent and Ivabradine that acts on cardiac pacemaker cells by selectively inhibiting the I(f)channel. Standard therapy had failed to control the tachycardia before. No side effects attributable to Ivabradine were noticed. Due to its mechanism of action Ivabradine is a promising novel agent for the therapy of tachycardia due to increased automaticity. Reports on the use of Ivabradine in young children or infants are rare, but show promising results for congenital junctional ectopic tachycardia. This report adds the second case of ectopic atrial tachycardia in this age group and novel treatment with Ivabradine to the literature

Case Report: Two episodes of hyperinflammation in an infant consistent with multisystem inflammatory syndrome in children: recurrence or rather two different diseases?

Multisystem inflammatory syndrome in children (MIS-C) is a hyperinflammatory disease that occurs after infection with severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). We report a 9-month-old male infant with two episodes of hyperinflammatory disease, each involving the coronary arteries, within a short period of time during the SARS-CoV-2 pandemic. Although both episodes met the official criteria for MIS-C, this case illustrates the difficulty in distinguishing MIS-C from its main differential diagnosis, Kawasaki disease (KD). Recurrence of postviral hyperinflammatory disease is rare. Compared with KD, the recurrence of MIS-C is even rarer, but clinicians should be aware of this possibility. Our case also emphasizes the need to follow up these patients closely and to detect sequelae regularly, especially cardiovascular sequelae, at an early stage

Successful non-invasive imaging of the coronary artery IMT in pediatric patients with Kawasaki disease using high-resolution echocardiography

Kawasaki Disease (KD) is a multisystemic vasculitis of medium- and small-sized arteries. Abnormal intimal thickening may develop in the involved arterial area after regression of coronary artery aneurysm (CAA). Intimal dysfunction may induce local stenosis or arteriosclerosis in the future. In this case–control study, we investigated 29 consecutive KD patients [20 male, median current age, 7.9 years; median follow-up duration, 5.7 years] and a group of 29 healthy matched controls (CON) [19 male, median current age, 10.8 years]. They were assesed and compared for CAA, LVFS, GCS, GLS, coronary artery (CA) Z scores, carotid intima-media thickness (IMT) and coronary artery IMT by high-resolution transthoracic echocardiography (hrTTE). Coronary artery IMT (caIMT) was significantly higher in patients with a maximal CA Z score > 2.5 in acute KD than in CON: KD caIMT: 0.62 mm [IQR, 0.57–0.72 mm] vs. 0.53 mm [0.51–0.60 mm], p = 0.043. CAAs were found in 15 (51.7%) patients with acute KD. The maximal median LCA Z score in acute KD was 2.57z [IQR, 1.93—3.2z] and in follow-up −0.39z [IQR, −1.25 to −0.36z]. There was no significant difference in carotid IMT between KD patients and CON. Signs of CA intima-media thickening were detected by hrTTE in patients with a maximal CA Z score > 2.5 in acute KD. These data indicate that these patients may be at risk for cardiovascular sequale even in the absence of permanent CA luminal abnormalities. Therefore long-term follow-up of this group of KD patients may be required

Neurocognitive and emotional long-term effects of COVID-19 infections in children and adolescents: results from a clinical survey in Bavaria, Germany

Background: While children and adolescents typically experience mild symptoms during the acute phase of the COVID-19 infection, some may develop severe post-infectious symptoms. In our study Post-COVID Kids Bavaria we integrated somatic and psychiatric aspects of the post-COVID syndrome to provide a holistic description of symptoms, provide early treatment, and detect possible risk factors associated with post-infectious neurocognitive and emotional impairments. Methods: We conducted an observational study involving 85 pediatric patients aged 12–17 years (M = 12.48, 61.2% female) who had confirmed COVID-19 infections and were experiencing persistent symptoms for at least 4 weeks. Our neuropsychological assessment comprised infection-specific patient interviews, psychopathological examinations, emotional well-being and behavioral difficulty questionnaires, and (computerized) tests assessing concentration, attention, and memory skills. Additionally, patients underwent neurologic, pneumologic, gastrointestinal, and cardiologic assessments. Results: Overall, the majority of patients reported experiencing elevated levels of fatigue (82.4%), loss of motivation (72.9%), concentration and attention deficits (71.8%), a worsened mood (53%), and a higher level of anxiety (31.8%). The most common diagnosis was the post-COVID adjustment disorder (ICD-10 F43.2, U09.9!; 38.8%) followed by the post-COVID attention deficit disorder (ICD-10 F98.80, U09.9!; 23.5%). Neuropsychiatric evaluation primarily identified deficits in sustained attention. There was a significant association between somatic and psychiatric post-COVID diagnoses. Patients with allergies exhibited a higher risk of developing a post-COVID adjustment disorder. For the post-COVID attention deficit disorder, age, sex, obesity, pre-existing psychiatric diagnosis, and the virus variant were relevant factors. Conclusions: Our findings indicate a diverse array of neuropsychiatric symptoms associated with the post-COVID syndrome, emphasizing the interconnectedness between somatic and neuropsychiatric diagnoses. To optimize treatment, comprehensive strategies involving both somatic and psychiatric professionals are crucial for addressing the syndrome’s complexity and managing symptoms effectively

Veno-arterial extracorporeal membrane oxygenation support for severe cardiac failure in a pediatric patient with intracranial hemorrhage after spontaneous aneurysmatic rupture

Introduction: Extracorporeal life support in adult patients with extended intracranial hemorrhage is controversial. In pediatric patients, it has traditionally been considered a contraindication as systemic anticoagulation may worsen the hemorrhage and neurological outcome. Case history: We present a nine-year-old female patient who was admitted with extended intracranial hemorrhage after spontaneous rupture of an aneurysm. On day four after the emergency craniotomy, she required veno-arterial extracorporeal membrane oxygenation for septic shock. Using an adapted anticoagulation protocol aimed at lower activated partial thromboplastin time target values, we did not observe any new bleeding or clotting complications during systemic anticoagulation and the patient had good neurological recovery. Conclusion: Extracorporeal life support with low dose systemic anticoagulation can be considered as a treatment option in pediatric patients after craniotomy for intracranial aneurysmatic hemorrhage

Epidemiological analysis of injury occurrence and current prevention strategies on international amateur football level during the UEFA Regions Cup 2019

Introduction Football is the most popular sport worldwide and results in a high frequency of injuries. So far, mainly injuries in professional football have been investigated, and the literature lacks data regarding detailed injury epidemiology and current prevention data in amateur football tournaments. Materials and methods A prospective cohort study investigated an international amateur football tournament, the UEFA Regions’ Cup, which took place in 2019 in Germany. Injury epidemiology, current prevention strategies of the teams and the implementation of the UEFA concussion protocol were investigated in detail by means of standardized injury definitions and data samples for football (Fuller et al., Scand J Med Sci Sports 16:83–92, https:// doi. org/ 10. 1111/j. 1600- 0838. 2006.00528.x, 2006). Results 138 player of 8 teams participated in this study, while 39 players were excluded. Overall injury incidence was 12.5 per 1000 h total football exposure, 43.5 per 1000 h for match exposure. No injuries were registered during training. Injury prevalence was 14.1% per player and 1.1 injuries per match were registered. The lower extremity was predominantly affected by injuries (71.4%) and the majority of injuries (78.6%) were non-severe injury types like contusions (50%) and sprains (18.2%). Two head injuries, one contusion and one skin lesion, were handled by the guidelines of the UEFA concussion protocol. 44.4% of the players indicated at least one previous injury before tournament, 45.3% of them during the last two football seasons before start of the tournament. Injury prevention performance was included in all participating teams during the tournament by warm up or training strategies (100%). During the warm-up program just 5 exercises of the FIFA 11 + program was detected by this investigation in participating teams to be done by more half of the teams. Running exercises were the most frequently performed exercises, while trunk muscle exercises were less represented (14.3%). Conclusion This study presents for the first time epidemiological injury and prevention data of the UEFA Regions Cup. Injury incidence was higher compared to injury reports of regular seasons, but lower compared to other amateur football tournaments. Currently used prevention programs revealed trunk muscle exercises as often neglected

Pathological Findings in Male and Female Semi-Professional Football Players from 11 to 14 Years—A Report of the Bavarian Football Association’s Pre-Participation Screening Program

Pre-participation screening (PPS) in professional junior football is common practice. However, football players (FP) from non-professional football clubs may also be exposed to health risks, both internal and musculoskeletal. Therefore, the Bavarian Football Association (BFV) implemented a cardiological and orthopedic screening program for semi-professional FP in 2014. The purpose of this study was to obtain and present epidemiological data of pre-adolescent and adolescent semi-professional FP, including cardiac pathologies, past injuries, and orthopedic disorders. This study represents a retrospective analysis of semi-professional FP aged 11 to 14 years participating in the PPS program from 2014 to 2018, including their medical history, cardiac risk profiles, and the results of undergoing orthopedic and sports cardiology examinations. Overall, 362 male and 162 female FP could be included. More than 20% of the FP indicated suffering from one or more medical conditions. Cardiac abnormalities were reported in 30 (5.7%) FP. Further cardiological diagnostics were recommended for 3% of the FP due to findings while undergoing the PPS. Orthopedic disorders could be detected in 51 (9.7%) FP. Of the reported injuries, 44.3% could be categorized as overuse injuries. In order to guarantee extensive preventive sports medical care for semi-professional junior FP, a PPS concept should include a basic orthopedic examination in addition to cardiological screening due to a high rate of overuse injuries and cardiac abnormalities among pre-adolescent and adolescent FP. Further studies are needed in junior football to gain epidemiological data on injury occurrence and cardiac abnormalities on an amateur level to evaluate possible PPS programs, even on an amateur level

Playing Football as a Risk Factor for Lower Leg Malalignment?—Comparing Lower Leg Axis of Male Adolescent Football Players and Referees

The prevalence of varus knee malalignment among junior and adult football players (FP) has proven to be higher compared to other sports. No causal relationship has yet been found, as genu varum can be assumed to be an independent risk factor for the development of knee osteoarthritis. The purpose of this study is to compare knee alignment measurements and sport-specific data of adolescent football players and referees (REF). Knee alignment was detected by measuring the intercondylar/intermalleolar distance (ICD/IMD) as well as the Hip–Knee–Ankle angle (HKA) using a standardized digital frontal-plane photograph. Anthropometric and sports-related data (training/match exposure, seasons actively played, etc.) were collected by means of questionnaires (Clinical trial registration number: DRKS00020446). A total of 28 male FP and 29 male adolescent REF were included in the survey. The mean age was 17.4 ± 0.7 years. The two groups did not differ significantly in age, height, weight, BMI, and overall football/refereeing exposure per week (FP vs. REF: 274 vs. 285 min/week, p = 0.61). The HKA of the FP was significantly lower (toward varus) than that of the REF (177.6° ± 2.4° vs. 179.0° ± 2.4°; p < 0.001). However, ICD did not significantly differ (FP: 17 ± 25 mm, REF: 13 ± 27 mm; p = 0.55). The football environment with frequent football exposure seems to have an influence on leg axis deviation in FP compared to REF. For prevention of knee osteoarthritis in FP, an advanced understanding of leg axis development in adolescent players is essential and, therefore, needs further research
