Isolated Tibial Tubercle Fracture With and Without Combined Patellar Tendon Avulsion: Early Outcomes, Complications, and Reoperations.

Background: Tibial tubercle fractures (TTF) are uncommon injuries, comprising <3% of proximal tibial fractures. Rarely, they occur in conjunction with patellar tendon avulsion (PTA). We aimed to compare reoperation rates and short-term postoperative outcomes in patients with TTF versus combined injuries.

From Sheep to Sling: Pediatric Injuries Due to Rodeo Mutton Bustin'.

Background: Mutton Bustin' was developed as a safer alternative to rough stock rodeo events such as bull riding to allow kids to participate in the rodeo. Children hold on to the bareback of a running sheep until they fall, competing to see who can ride the longest. While reports of injuries due to other rodeo events are well described in the literature, there are no reports of Mutton Bustin'-associated injuries.

Evaluating One-Week Post-Casting Alignment Checks and Surgical Intervention Rates in Pediatric Type IIA Supracondylar Humeral Fractures.

Background: This study aims to determine the rate of surgical intervention in children with type IIA supracondylar humerus fractures (SCHF) following routine post-casting radiographic assessment. We hypothesized that no cases would convert to operative management following one-week post-casting alignment assessments.

Methods: This single-center retrospective study focused on pediatric patients diagnosed with type IIA SCHF from 2019 to 2022.

Synapse-specific catecholaminergic modulation of neuronal glutamate release.

Norepinephrine in vertebrates and its invertebrate analog, octopamine, regulate the activity of neural circuits. We find that, when hungry, larvae switch activity in type II octopaminergic motor neurons (MNs) to high-frequency bursts, which coincide with locomotion-driving bursts in type I glutamatergic MNs that converge on the same muscles. Optical quantal analysis across hundreds of synapses simultaneously reveals that octopamine potentiates glutamate release by tonic type Ib MNs, but not phasic type Is MNs, and occurs via the G-coupled octopamine receptor (OAMB).

Brain volumes, cognitive, and adaptive skills in school-age children with Down syndrome.

Background: Down syndrome (DS) is the most common congenital neurodevelopmental disorder, present in about 1 in every 700 live births. Despite its prevalence, literature exploring the neurobiology underlying DS and how this neurobiology is related to behavior is limited. This study fills this gap by examining cortical volumes and behavioral correlates in school-age children with DS.
