Pathophysiology Of Dyt1 Dystonia: Targeted Mouse Models, Chad Christopher Cheetham
Pathophysiology Of Dyt1 Dystonia: Targeted Mouse Models, Chad Christopher Cheetham
All ETDs from UAB
DYT1 dystonia is an inherited movement disorder caused by a trinucleotide deletion (DeltaGAG) in the DYT1 (TOR1A) gene, which codes for the torsinA protein. Dr. Yuqing Li's laboratory previously reported the characterization of a DYT1 dystonia mouse model, a knock-in carrying DeltaGAG in Dyt1 (KI), which displays a motor learning deficit of motor skill transfer. We report here that this motor learning deficit was reversed with an anticholinergic drug, trihexyphenidyl (THP), a drug commonly used to treat movement problems in dystonia patients. We further show a potential substrate for the pathophysiology, a reduction in D2 receptors in the striatum in …
Pediatric Obesity And Traumatic Lower Extremity Long Bone Fracture Outcomes, Ian Charles Backstrom
Pediatric Obesity And Traumatic Lower Extremity Long Bone Fracture Outcomes, Ian Charles Backstrom
All ETDs from UAB
Background: Pediatric obesity is associated with lower extremity injuries and poor outcomes after blunt trauma. Our aim was to determine if obese pediatric patients with femur and tibia fractures have more severe injury patterns and worse outcomes compared to non-obese patients. Methods: We performed a retrospective cohort study of obese and non-obese pediatric patients with femur or tibia fractures treated at two Level-1 trauma centers from 2004-2010. Patients weighing ≥ 95th percentile for age and gender were classified as obese. Patients were compared regarding demographics, Injury Severity Score (ISS), intra-abdominal, and orthopedic injuries. Outcomes included fracture treatment, orthopedic complications, ICU …
