Navigation-Assisted Minimally Invasive Direct Pars Repair For Lumbar Spondylolysis., Jack Mangan, Richard M. Schwend, John Anderson, Michael Benvenuti, K Aaron Shaw

Manuscripts, Articles, Book Chapters and Other Papers

Spondylolysis is a common cause of mechanical low back pain in adolescent athletes. While nonoperative management is frequently successful, a subset of patients fail conservative treatment and require surgical intervention. Direct repair of the pars defect offers a motion-preserving alternative to fusion in appropriately selected patients, but traditional open and fluoroscopy-guided minimally invasive techniques are limited by soft-tissue morbidity and variability in screw placement accuracy, and detailed technical descriptions of navigation-assisted approaches remain limited in the literature. We present a detailed, illustrated technique for navigation-assisted minimally invasive direct pars repair, in which a single midline incision accommodates bilateral fixation with …

Mccrindle, International Kawasaki Disease Registry

Manuscripts, Articles, Book Chapters and Other Papers

Kawasaki disease (KD) and Multisystem Inflammatory Syndrome in Children (MIS-C) are systemic inflammatory diseases sharing clinical and laboratory features. Gastrointestinal (GI) symptoms are common presenting features of both conditions. We aimed to determine the association of GI symptoms and clinical features and outcomes for KD and MIS-C. The International Kawasaki Disease Registry enrolled contemporaneous KD and MIS-C patients <  18 years of age from 42 sites from January 1, 2020, through October 31, 2023. The association of GI symptoms (abdominal pain, vomiting and diarrhea), demographics, clinical and laboratory features, and cardiac involvement were determined using ordinal logistic regression incorporating interaction terms with diagnosis. We included 883 KD and 1827 MIS-C patients with confirmed diagnostic criteria. The presence of at least one GI symptom (vomiting, abdominal pain, diarrhea) was more prevalent for MIS-C patients (88% versus 57%; p <  0.001). A greater number of GI symptoms was significantly associated with older age and higher adiposity, presentation with shock, intensive care unit admission, inotropic support, and greater immunomodulatory therapy. Greater number of GI symptoms was significantly associated with higher peak markers of inflammation and organ dysfunction, and higher peak NT-proBNP and lower left ventricular ejection fraction, but not with coronary artery involvement. There were few differences related to diagnosis group. A greater number of presenting GI features is associated with features that may indicate a more severe form of KD and MIS-C, including cardiac involvement, and may merit increased attention.

Patient-Specific Computational Fluid Dynamics Modeling Of Airway Collapse In Infants With Robin Sequence., Gautam Jalori, Michael Barbour, Michael Bindschadler, Kelly Evans, John P. Dahl, Alberto Aliseda

Manuscripts, Articles, Book Chapters and Other Papers

Robin Sequence (RS) is a congenital condition in which patients experience dynamic, periodic obstruction or collapse of the upper airway due to an underdeveloped jaw and a posteriorly displaced tongue. Current clinical techniques for evaluating airway obstruction do not provide quantifiable data and fail to account for the dynamic nature of obstruction or collapse. There is no standardized criterion to characterize obstruction or collapse severity. This study presents the first method that extracts airway motion from 4-dimensional computed tomography and performs a patient-specific, moving-mesh computational fluid dynamics (CFD) analysis of RS patients with complete airway collapse or obstruction. To quantify …

Pharmacogenetics In Pediatric Cardiology., Adenike Adenikinju, Jonathan B. Wagner, Mollie Walton

Manuscripts, Articles, Book Chapters and Other Papers

Children with congenital and acquired heart disease frequently require complex and prolonged pharmacotherapy, often involving off-label cardiovascular medications with narrow therapeutic ranges. Consequently, variability in drug response and medication-related adverse events remains a significant clinical challenge in pediatric cardiology. Pharmacogenetics provides a framework to individualize drug selection and dosing by incorporating genetic variability alongside established clinical and developmental factors. This review outlines the current clinical utility and emerging role of pharmacogenetics in pediatric cardiology, emphasizing applications most relevant to day-to-day patient care. Established pharmacogenetic associations with direct implications for pediatric cardiac practice include gene-drug pairs involving tacrolimus (CYP3A5), …
