Cardiac and Inflammatory Necrotizing Enterocolitis in Newborns Are Not the Same Entity.

Front Pediatr 2020 6;8:593926. Epub 2021 Jan 6.

Department of Pediatric Surgery, University Medical Center Hamburg-Eppendorf, Hamburg, Germany.

Necrotizing enterocolitis (NEC) is an often-fatal neonatal disease involving intestinal hyperinflammation leading to necrosis. Despite ongoing research, (1) conflicting results and (2) comorbidities of NEC patients make early NEC detection challenging and may complicate therapy development. Most research suggests that NEC pathogenesis is multifactorial, involving a combination of (1) gut prematurity; (2) abnormal bacterial colonization; and (3) ischemia-reperfusion (I/R) injury.

Untwisting the complexity of midgut malrotation and volvulus ultrasound.

Pediatr Radiol 2021 Apr 4;51(4):658-668. Epub 2021 Jan 4.

Singleton Department of Radiology, Texas Children's Hospital, 6701 Fannin St., Houston, TX, 77030, USA.

Abdominal US is emerging as an alternative to the upper gastrointestinal (GI) series as the preferred diagnostic imaging test for midgut malrotation complicated by volvulus. Unlike the upper GI series, US is free from ionizing radiation, does not require oral contrast agent, and can be performed portably and at times remotely from the interpreting radiologist, expediting diagnosis. Although some institutions do not have a standardized US protocol for midgut volvulus, many routinely use US in the setting of an infant or child with acute abdominal signs or symptoms to evaluate for common conditions such as hypertrophic pyloric stenosis, intussusception, necrotizing enterocolitis and appendicitis.

Patent ductus arteriosus and cerebral, cardiac, and gut hemodynamics in premature neonates.

Semin Fetal Neonatal Med 2020 10 2;25(5):101120. Epub 2020 Jun 2.

Division of Neonatology, Department of Pediatrics, University of Iowa, 200 Hawkins Drive, Iowa City, IA, 52242, USA; Department of Internal Medicine, University of Iowa, 8803 John Pappajohn Pavillion 200 Hawkins Drive, Iowa City, IA, 52242, USA. Electronic address:

Patent ductus arteriosus is associated with multiple comorbidities in premature infants, however a causal link or strategy to decrease these morbidities has not been found. The association between the patent ductus arteriosus and morbidities has biologic plausibility as, like any cardiac mixing lesion, a significant systemic to pulmonic shunt may lead to pulmonary over-circulation and systemic hypoperfusion. Understanding the underlying pathophysiology of associated morbidities in the setting of a patent ductus arteriosus may aid in risk stratifying infants and offer a patient targeted approach to infants with a pathological ductal shunt.
