Congenital segmental dilatation of the colon in a newborn: a radiologic perspective of an unusual entity.

A newborn with congenital segmental dilatation of the intestine affecting the colon is presented. This rare condition, unrelated to Hirschsprung's disease, may affect any portion of the bowel and is characterized by focal dilatation of a segment of bowel flanked by normal proximal and distal bowel. While reported in the surgical literature, congenital segmental dilatation of the intestine has not been reported in the pediatric radiology literature even though pediatric radiologists may be the first to encounter imaging suggesting the diagnosis.

Magnetic resonance imaging following the demonstration of a normal common bile duct on ultrasound in children with suspected choledocholithiasis: what is the benefit?

Background: The role of MRI in evaluating children with an in situ gallbladder and suspected choledocholithiasis following a negative or inconclusive US is unclear.

Objective: To determine whether MRI benefits children with suspected choledocholithiasis and a normal common bile duct (CBD) without stones on US.

Materials And Methods: We conducted a retrospective 10-year review of paired US and MRI (within 10 days) in children 18 years or younger with suspected choledocholithiasis.

Utilizing community engagement studios to inform clinical trial design at a Center of Excellence for Alzheimer's Disease.

Despite the disproportionate burden of Alzheimer's disease in older adults of color, the scientific community continues to grapple with underrepresentation of racial and ethnic minorities in clinical research. Our Center of Excellence for Alzheimer's Disease (CEAD) collaborated with a local community partner to conduct community engagement (CE) studios to effectively involve our community of diverse older adults in the early planning stages of a clinical trial. Given the COVID-19 pandemic, the in-person studio format was adapted to allow for virtual, real-time participation.
