Clinical trials and studies with ivabradine implicate cardiac pacemaker channels (HCN4) in the pathogenesis of atrial arrhythmias. Because acute changes in cardiac autonomic tone predispose to atrial arrhythmias, we studied humans in whom profound cardiac sympathetic activation was rapidly relieved to test influences of HCN4 inhibition with ivabradine on atrial arrhythmias. We tested 19 healthy participants with ivabradine, metoprolol, or placebo in a double blind, randomized, cross-over fashion on top of selective norepinephrine reuptake inhibition with reboxetine...

BACKGROUND: Globally, complications of prematurity are the leading cause of death in children under five. Preterm infants who survive their first month of life are at greater risk for various diseases and impairments in infancy, childhood and later life, representing a heavy social and economic burden for families, communities and health and social systems. Kangaroo mother care (KMC) is recommended as a beneficial and effective intervention for improving short- and long-term preterm birth outcomes in low- and high-income settings...

OBJECTIVES: This study hypothesizes that post-extrasystolic potentiation reflects left ventricle contractile reserve and therefore may predict an improvement of premature ventricular contraction (PVC)-induced cardiomyopathy after PVC ablation. BACKGROUND: Post-extrasystolic potentiation is a physiologic phenomenon of blood pressure accentuation after a PVC beat. METHODS: We performed a retrospective study of patients with a PVC burden of ≥10% PVC/24 h and left ventricular ejection fraction (LVEF) of <50% who underwent successful ablation between January 1, 2009, to June 30, 2015...

BACKGROUND: The quality of mother-preterm infant interaction has been identified as a key factor in influencing the infant's later development and language acquisition. The relationship between mother-infant responsiveness and later development may be evident early in infancy, a time period which has been understudied. AIM: Describe the relationship between mother-infant mutual dyadic responsiveness and premature infant development. DESIGN: This study employed a secondary analysis of data from the 6-week corrected age (CA) follow-up visit of the Hospital-Home Transition: Optimizing Prematures' Environment (H-HOPE) study, a randomized clinical trial testing the efficacy of a mother- and infant- focused intervention for improving outcomes among premature infants...

OBJECTIVE: Recent studies suggest an association between Human Papilloma Virus (HPV) infection, cervical inflammation and obstetric complications (i.e. spontaneous preterm parturition and cervical insufficiency). It has been proposed that viral inflammation of the placenta causes changes in the mother's immune reaction to bacterial pathogens, which leads to enhanced inflammatory reaction and preterm delivery. Therefore, the aim of this population-based study was to determine the association between abnormal cervical cytology prior to pregnancy and obstetric outcomes...

OBJECTIVE Perinatal intraventricular hemorrhage (IVH) in premature neonates may lead to severe neurological disability and lifelong treatment requirement for consecutive posthemorrhagic hydrocephalus (PHHC). Early CSF diversion as a temporizing measure, or a permanent ventriculoperitoneal shunt (VPS), is the treatment of choice. Preterm neonates are not only at high risk for different perinatal but also for treatment-related complications. The authors reviewed their institutional neurosurgical management for preterm neonates with IVH-related PHHC and evaluated shunt-related surgical outcome for this particular hydrocephalus etiology after completion of a defined follow-up period of 5 years after initial shunt insertion...

Whereas familial forms of complex disorders/differences of sex development have been widely reported, data regarding isolated hypospadias are sparse and a family history is thought to be less frequent. We aimed 1-to determine the frequency of hypospadias in families of hypospadiac boys 2-to determine if theses familial forms exhibit a particular phenotype 3-to evaluate the prevalence of genetic defects of the main candidate genes. A prospective inclusion of 395 hypospadiac boys screened for family history with a standardized questionnaire, extensive clinical description, family tree and sequencing of AR, SF1, SRD5A2 and MAMLD1 was performed...

BACKGROUND: Brugada syndrome (BrS) is known to cause malignant ventricular arrhythmia (VA) and sudden cardiac death (SCD). Patients with implantable cardioverter defibrillator (ICD) may experience recurrent shocks from ICD. Recent reports indicate that radiofrequency ablation (RFA) in BrS is feasible, and effective. Catheter ablation of premature ventricular complexes (PVCs) triggering VA and substrate modification of right ventricular outflow tract (RVOT) has been described. METHODS AND RESULTS: Five patients (4 males, age-23 to 32 years) with BrS and electrical storm (ES) despite being on isoprenaline infusion and cilostazol (phosphodiestrase-3 inhibitor) underwent 3 dimensional electroanatomic mapping and RFA...

Introduction: Severe neonatal hyperbilirubinemia can cause mortality and serious morbidities. When phototherapy fails, neonates with severe hyperbilirubinemia should undergo double volume blood exchange transfusion (BET). As this procedure carries a significant risk of mortality and morbidity, adopting guidelines for the treatment of neonatal hyperbilirubinemia is critical to avoid hyperbilirubinemia toxicity and also the complication of an unindicated procedure. Methods: This study investigated the causes, complications, and trend of BET rate in our unit over a 13-year period...
