Echocardiographic assessment of cardiovascular involvements in children with cystic fibrosis.

Background: Over the past four decades, numerous case reports and clinical studies have highlighted the presence of heart disease in individuals with cystic fibrosis. Given the limited information in this field and the imperative to identify early changes during childhood, our study aims to explore cardiac dysfunction in patients with cystic fibrosis using echocardiography.

Methods: In this case-control study, we examined echocardiographic findings from thirty-three patients with cystic fibrosis and sixty healthy children.

Pulmonary Artery Sling Associated with Stridor from Early Infancy: A Case Report.

Background: Pulmonary artery sling is a rare condition in which the left pulmonary artery anomalously originates from a normally positioned right pulmonary artery. The left pulmonary artery arises anterior to the right main bronchus, courses between the trachea and esophagus then enters the left hilum. Respiratory symptoms such as wheezing, stridor, cough, and dysphasia are common in this anomaly.

Comparison of QT dispersion before and after PDA device closure in pediatrics.

Background: Numerous studies have shown that QT dispersion (QTd) can be a suitable criterion for risk assessment of arrhythmia in patients with congenital heart disease. Pulmonary arterial hypertension (PAH) increases the risk of cardiac arrhythmia by changing ventricular repolarization homogeneity. In this study, we assessed QTd changes after PDA device closure and the effect of PAH on these changes.

A Rare Case of Cardiac Hydatid Disease without Liver and Lungs Involvement.

Hydatid disease is a parasitic infection caused by . Cardiac involvement is rare especially without liver and lungs tissue involvement. We describe a 12-year-old male patient referred to Mofid Children's Hospital, Tehran, Iran in Jul 2020 due to chronic pericardial effusion and suspected tuberculosis infection from Afghanistan.

Comparison of the Effect of Nifedipine Alone and the Combination of Nifedipine and Sildenafil in Delaying Preterm Labor: A Randomized Clinical Trial.

Recently, sildenafil as a drug effective in relaxing smooth muscles can be used as an adjunct to delay the onset of uterine contractions and therefore the occurrence of preterm labor. The aim of this study was to evaluate the effect of nifedipine combination with sildenafil on preterm delivery compared with nifedipine alone. This randomized double-blinded clinical trial was performed on pregnant women with a gestational age of 26-34 weeks with singleton pregnancy and symptoms of preterm delivery.

Acute Lymphoblastic Leukemia with Eosinophilia and Strongyloides stercoralis Hyperinfection.

Background: Acute lymphoblastic leukemia (ALL) is the most common malignancy in children. Bone pain is an important symptom that can be severe. Eosinophilia without any other abnormal laboratory findings is rare in ALL.
