Cardiovascular manifestations and cardiac magnetic resonance follow-up of multisystem inflammatory syndrome in children (MIS-C).

OBJECTIVE: This study aimed to evaluate the cardiovascular manifestations and surveillance of multisystem inflammatory syndrome in children (MIS-C) and to determine the correlation of echocardiographic findings with cardiac magnetic resonance imaging findings. METHODS: Forty-four children diagnosed as MIS-C with cardiac involvement were enrolled in this observational descriptive study. The diagnosis of MIS-C was made according to the criteria of Centers for Disease Control and Prevention. Clinical findings, laboratory parameters, and electrocardiographic and echocardiographic findings at the time of diagnosis and during follow-up were evaluated. Cardiac magnetic resonance was performed on 28 (64%) cases. The 1-year follow-up imaging was performed in all cases with abnormal initial cardiac magnetic resonance findings. RESULTS: Forty-four patients (56.8% male) with a mean age of 8.5 ± 4.8 years were enrolled in this study. There was a significant positive correlation between high-sensitivity cardiac troponin T (mean: 162 ± 444.4 pg/ml) and N-terminal pro b-type natriuretic peptide (mean: 10,054 ± 11,604 pg/ml) (p < 0.01). Number of cases with an electrocardiographic and echocardiographic abnormality was 34 (77%) and 31 (70%), respectively. Twelve cases (45%) had left ventricular systolic dysfunction and 14 (32%) cases had pericardial effusion on admission. Three cases (11%) had cardiac magnetic resonance findings that may be attributed to the presence of myocardial inflammation, and pericardial effusion was present in seven (25%) cases. Follow-up cardiac magnetic resonances of all cases were normal. Cardiac abnormalities were completely resolved in all except two cases. CONCLUSIONS: Myocardial involvement can be seen during acute disease, but MIS-C generally does not lead to prominent damage during a year of surveillance. Cardiac magnetic resonance is a valuable tool to evaluate the degree of myocardial involvement in cases with MIS-C.

Complications of epicutaneo-caval catheters: Pericardial effusion and cardiac tamponade in three preterm infants.

In the neonatal intensive care units (NICU), epicutaneo-caval catheters (ECCs) are common alternative vascular routes. Pericardial effusion (PCE) and cardiac tamponade (CT) are rare but serious complications in infants with ECCs. It may be asymptomatic or present with a variety of significant clinical signs, including dyspnea, bradycardia, sudden asystole, and hypotension. If untreated, PCE can be fatal. This report presents, three cases of ECC-associated PCE/CT during NICU stay. All three patients were born before 30 weeks of gestation and weighed less than 1500 g. Echocardiography was used for diagnosis all patients. PCE/CT was detected incidentally in one patient and after hemodynamic deterioration in the other two. In one patient, CT was developed due to catheter malposition, and the other two patient, the catheter tip was found in the right atrium. PCE did not recur in any of the patients after pericardial fluid was drained and the catheters were removed. No PCE/CT-related deaths were observed. In all three patients, X-ray was used to evaluate the location of the catheter tips. However, after clinical deterioration, echocardiography showed that in the first two cases the tips were actually in the right atrium. Real-time ultrasound was suggested with strong evidence to evaluate the location of the catheter tip and to detect secondary malapposition. PCE/CT should be considered in the presence of unexplained and refractory respiratory distress, abnormal heart rate and blood pressure, and metabolic acidosis in a neonate with ECC. Early diagnosis and prompt pericardiocentesis are essential to reduce mortality and improve prognosis. Prospective studies with educational interventions should be designed to demonstrate that the use of point-of-care ultrasound (POCUS) can be easily acquired and may reduce complications.

The effects of anxiety about their parents getting COVID-19 infection on children's mental health.

Although the effects of COVID-19 on children's physical health are relatively less serious, it is known that pandemic has serious effects on children's mental health. Anxiety and related symptoms increase among children during this period. The main purpose of this study is to measure children's anxiety about their parents and themselves with structured scales. Children who applied to the pediatric outpatient clinic were included in the study. Participants were asked questions about their parents' and their own concerns about getting COVID-19. Psychiatric symptoms of the participants were evaluated with the Revised Child Anxiety and Depression Scale, the Coronavirus Anxiety Scale, and Anxiety Sensitivity Index for Children. Increased social phobia, separation anxiety, generalized anxiety, total anxiety, total internalizing disorder scores, increased anxiety sensitivity, and increased coronavirus anxiety were detected among children who have increased subjective anxiety for themselves about getting COVID-19. In addition, increased social phobia, depression, separation anxiety, generalized anxiety, total anxiety, total internalizing disorder scores, and anxiety sensitivity were also detected among children who have increased subjective anxiety for their parents about getting COVID-19. In logistic regression, panic, separation anxiety, and generalized anxiety scores significantly predicted children's anxiety for their parents, and separation anxiety and generalized anxiety were shown to predict anxiety for themselves. CONCLUSION: Children who have increased subjective anxiety about their parents and themselves also have increased anxiety, anxiety sensitivity, and coronavirus anxiety scores. This is the first study which determines that children who are worried about their parents and themselves have higher levels of anxiety, depression symptoms, and anxiety sensitivity. WHAT IS KNOWN: • Although COVID19 pandemic's negative effects on the mental health of children and adolescents has been investigated and consistently demonstrated, the children's anxiety about their parents getting infection were less researched. WHAT IS NEW: • Children's anxiety about their parents getting SARS-Cov-2 infection was investigated with the questionnaires. • The scale scores of the children who expressed their anxiety with open-ended questions were statistically significantly higher.

The Safety and Tolerability of Nebivolol in Hypertensive Patients with Coronary Artery Disease and Left Ventricular Ejection Fraction ≥ 40%: A Population-Based Cohort Study (Nebivolol-TR Study).

BACKGROUND: This study aimed to assess the safety and tolerability of nebivolol in hypertensive patients with coronary artery disease and left ventricular ejection fraction ≥ 40% in a Turkish cohort. METHODS: A total of 1015 hypertensive patients and coronary artery disease with left ventricular ejection fraction ≥ 40% were analyzed from 29 different centers in Turkey. Primary outcomes were the mean change in blood pressure and heart rate. Secondary outcomes were to assess the rate of reaching targeted blood pressure (<130/80 mmHg) and heart rate (<60 bpm) and the changes in the clinical symptoms (angina and dyspnea). Adverse clinical events and clinical outcomes including cardiovascular mortality, cardiovascular hospital admissions, or acute cardiac event were recorded. RESULTS: The mean age of the study population was 60.3 ± 11.5 years (male: 54.2%). During a mean follow-up of 6 months, the mean change in blood pressure was -11.2 ± 23.5/-5.1 ± 13.5 mmHg, and the resting heart rate was -12.1 ± 3.5 bpm. Target blood pressure and heart rate were achieved in 76.5% and 37.7% of patients. Angina and functional classifications were improved by at least 1 or more categories in 31% and 23.2% of patients. No serious adverse events related to nebivolol were reported. The most common cardiovascular side effect was symptomatic hypotension (4.2%). The discontinuation rate was 1.7%. Cardiovascular hospital admission rate was 5% and hospitalization due to heart failure was 1.9% during 6 months' follow-up. Cardiovascular mortality rate was 0.1%. CONCLUSION: Nebivolol was well tolerated and safe for achieving blood pressure and heart rate control in hypertensive patients with coronary artery disease and heart failure with preserved or mildly reduced ejection fraction.

Venlafaxine intoxication in an adolescent presenting with severe lactic acidosis.

Venlafaxine is a selective serotonin noradrenaline reuptake inhibitor and commonly prescribed antidepressant in adults. Most patients overdosing with venlafaxine develop only mild symptoms. Severe toxicity is reported with the most common symptoms being CNS depression, serotonin toxicity, seizure, or cardiac conduction abnormalities. However, lactic acidosis is an uncommon adverse effect. Here, we present the first case in the literature reporting lactic acidosis due to venlafaxine overuse in an adolescent.
