Article Synopsis
  • The study investigates the effectiveness of enoxaparin, a medication for preventing blood clots, in critically ill children, focusing on differences in response based on age, particularly between older children and infants.
  • It consists of two simultaneous clinical trials: one for older children aged 1-17 years, and another for infants under 1 year, with specific dosing protocols for each group.
  • The trials are set in multiple pediatric intensive care units across the U.S., using methods like randomization, ultrasonography, and blood analysis to assess outcomes and monitor safety.

Correlated phases in Moiré materials together with the flat-bands in twisted systems play a central role to explain superconductivity in the new twisted bilayer graphene. In this paper, flat-bands are shown to exist in both translated and twisted bilayer of quasicrystals. Such flat-bands arise for different displacements and twisting angles of two-coupled Penrose lattices where Moiré patterns are also shown.

Objectives: As point-of-care ultrasound (POCUS) has emerged as a valuable tool for intussusception screening, this quality improvement study aimed to implement a "POCUS-first" pathway in a Pediatric Emergency Department (ED) to streamline workflow and expedite care for children with suspected intussusception.

Methods: This was a prospective analysis of children diagnosed with ileocolic intussusception in a Pediatric ED between June 2022 and June 2023. The study compared the "POCUS-first" cohort with the group receiving only radiology-performed ultrasound.

Pediatric neoplastic extraocular soft-tissue lesions in the orbit are uncommon. Early multimodality imaging work-up and recognition of the key imaging features of these lesions allow narrowing of the differential diagnoses in order to direct timely management. In this paper, the authors present a multimodality approach to the imaging work-up of these lesions and highlight the use of ocular ultrasound as a first imaging modality where appropriate.

Article Synopsis
  • Orbital pathologies are categorized into four main types: ocular, extraocular soft-tissue (both neoplastic and non-neoplastic), osseous, and traumatic issues.
  • The paper focuses on imaging features and differential diagnoses for various orbital conditions, including congenital lesions like dermoid cysts, infections, inflammatory issues, and non-neoplastic vascular anomalies, using CT and MRI as key imaging tools.
  • It also highlights the importance of ocular ultrasound in diagnosing certain conditions, particularly dermoid cysts and chalazion, as well as its primary use in identifying vascular malformations.
