Clinical characteristics and outcomes of atrial flutter in neonates.

Background: Atrial flutter is an uncommon arrhythmia that can cause severe morbidity, including heart failure and even death in refractory cases. This study investigated the clinical characteristics, treatment, and long-term outcomes of patients with neonatal atrial flutter and its association with heart failure.

Methods: We retrospectively reviewed atrial flutter cases observed in our center between 1999 and 2021 and analyzed the clinical characteristics, treatment, and recurrence according to the presence of heart failure.

Postoperative Complications of Esophageal Atresia and Role of Endoscopic Balloon Dilatation in Anastomotic Strictures.

Purpose: Esophageal atresia (EA) with or without tracheoesophageal fistula (TEF) is a congenital anomaly that can cause frequent digestive and nutritional problems, even after repair. The most common complication is anastomotic stricture, for which reoperation or balloon dilatation is performed. This study aimed to evaluate the postoperative complications of EA and the role of endoscopic balloon dilatation (EBD) in cases of anastomotic stricture.

The Prevalence of Symptomatic Congenital Cytomegalovirus Disease in Korea; A 15-Year Multicenter Study and Analysis of Big Data From National Health Insurance System.

The birth prevalence of symptomatic congenital cytomegalovirus (cCMV) disease among live birth in Korea from a multicenter study was 0.06% during 2001-2015 with increasing frequency. The administrative prevalence of cCMV infection by big-data analysis from the national health insurance system was 0.

Surgical Management of Total Sternal Cleft in a Pentalogy of Cantrell Neonate.

Sternal cleft is a rare malformation with significant morbidity and mortality. It has been associated with other midline fusion defects, most significantly Cantrell's pentalogy, involving the sternum, pericardium, heart, diaphragm, and abdominal wall. This study reported a successfully managed case of a newborn with a total sternal cleft and Cantrell's pentalogy.

Pancreatic involvement in patients with inborn errors of metabolism.

Background: Repeated inflammation of the pancreas can cause pancreatitis or diabetes. It is well recognized that the organic acidemias may be complicated by pancreatitis but less recognized are other metabolic disorders in which pancreatitis can occur. This study shows that long-term follow-up of patients with various metabolic disorders in Korea revealed several with episodes of isolated pancreatitis or diabetes concomitantly with pancreatitis.

Modification of nutrition strategy for improvement of postnatal growth in very low birth weight infants.

Purpose: To identify the effects of modified parenteral nutrition (PN) and enteral nutrition (EN) regimens on the growth of very low birth weight (VLBW) infants.

Methods: The study included VLBW infants weighing <1,500 g, admitted to Chungnam National University Hospital between October 2010 and April 2014, who were alive at the time of discharge. Subjects were divided according to 3 periods: period 1 (n=37); prior to the PN and EN regimen being modified, period 2 (n=50); following the PN-only regimen modification, period 3 (n=37); following both PN and EN regimen modification.

Successful use of low molecular weight heparin in intracardiac thrombus of an extremely low birth weight infant.

The sick premature infants have high risk for thrombosis. Although therapeutic options include close observation, anticoagulation, thrombolytic therapy, and thrombectomy, guidelines for the management of neonatal arterial and venous thrombosis vary greatly among different centers. The authors report their experience using low molecular weight heparin (enoxaparin), with safe and successful resolution of right atrial thrombus, in an extremely low birth weight infant.
