Neonatal Renal Failure in the Setting of Anorectal Malformation: A Case Report and Literature Review.

Cureus 2021 May 12;13(5):e14984. Epub 2021 May 12.

Pediatric Surgery, University of Missouri Kansas City School of Medicine, Kansas City, USA.

Anorectal malformations (ARMs) can occur in isolation or in association with other anomalies, most commonly those of the genitourinary systems. Morbidity and mortality are highest among patients who develop end-stage renal disease (ESRD) either from severe congenital anomalies (dysplastic kidneys) or from repeated infections in those who have vesicoureteral reflux or persistent recto-urinary fistulas. We describe our management strategy for a patient born with an ARM and bilateral dysplastic kidneys to highlight the nuances and complex decision-making considerations required in taking care of this complex patient population.

Hyaluronan, a double-edged sword in kidney diseases.

Pediatr Nephrol 2021 May 19. Epub 2021 May 19.

Laboratory for Regenerative Tissue Repair, Division of Pediatric Surgery, Department of Surgery, Texas Children's Hospital/Baylor College of Medicine, Houston, TX, 77030, USA.

Over the years, hyaluronic acid (HA) has emerged as an important molecule in nephrological and urological studies involving extracellular matrix (ECM) organization, inflammation, tissue regeneration, and viral sensing. During this time, many have noted the perplexing double-edged nature of the molecule, at times promoting pro-fibrotic events and at other times promoting anti-fibrotic events. Different molecular weights of HA can be attributed to these disparities, though most studies have yet to focus on this subtlety. Read More

Contrast-enhanced ultrasound of transplant organs - liver and kidney - in children.

Pediatr Radiol 2021 May 12. Epub 2021 May 12.

Department of Radiology and Medical Imaging, University of Virginia Children's Hospital, Charlottesville, VA, USA.

Ultrasound (US) is the first-line imaging tool for evaluating liver and kidney transplants during and after the surgical procedures. In most patients after organ transplantation, gray-scale US coupled with color/power and spectral Doppler techniques is used to evaluate the transplant organs, assess the patency of vascular structures, and identify potential complications. In technically difficult or inconclusive cases, however, contrast-enhanced ultrasound (CEUS) can provide prompt and accurate diagnostic information that is essential for management decisions.
