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 …

High-Fidelity Simulation Model For The Posterior Sagittal Anorectoplasty In Anorectal Malformations With Rectovestibular And Rectourethral Fistula., Tobias Jhala, Lukas Bischoff, Ismael Elhalaby, Jonathan Aichner, Jörg Fuchs, Marc A. Levitt, Rebecca M. Rentea

Manuscripts, Articles, Book Chapters and Other Papers

BACKGROUND: Surgical training for posterior sagittal anorectoplasty (PSARP) in anorectal malformations is limited by the rarity of the condition and restricted operative exposure. Existing low-cost simulators facilitate learning of procedural steps but lack realistic tissue characteristics and anatomical fidelity.

METHODS: A high-fidelity animal-tissue simulation model was developed using poultry slaughter by-products. The model combines the perineal anatomy of a chicken with a segment of turkey esophagus to recreate multilayer tissue structures and simulate rectovestibular and rectourethral fistulae. Model construction and surgical simulation were designed to reflect the standardized operative steps for PSARP defined by international consensus.

RESULTS: The model reproduces …

Murine Typhus In Georgia: Historical Context And A Probable Case Of Resurgence Where Previously-Thought Eradicated, Giovanni Mella-Velazquez, Christopher He, Bolanle Akinsola, Judson Miller

Journal of the Georgia Public Health Association

Background: Murine typhus, caused by Rickettsia typhi, is a flea-borne illness historically endemic to the southeastern United States, with initial cases reported in Atlanta, Georgia in 1913. Following vector control efforts, incidence declined significantly, and the disease was removed from the nationally notifiable disease list in 1987. While recent cases have been reported in select regions, murine typhus has not been documented in Georgia for decades. We present a pediatric case in Atlanta that may represent the first reported instance in nearly 40 years, suggesting possible reemergence in the Southeast.

Methods: We conducted a case report analysis of a pediatric …

Notch2 Vus Interpretation In Pediatric Cholestasis: A 365-Variant Landscape And Genotype-Phenotype Analysis Of 7 Cases, Brett J. Hoskins, Tiziano Pramparo, Shannon M. Vandriel, Chaowapong Jarasvaraparn, Michael J. Wilsey, Voytek Slowik, Lakshmi Kunam, Janis M. Stoll, Ruben E. Quiros-Tejeira, Simon Lam, Wikrom Karnsakul

Manuscripts, Articles, Book Chapters and Other Papers

Background/Objectives: Interpretation of NOTCH2 variants of uncertain significance (VUSs) remains challenging in pediatric cholestasis and suspected Alagille syndrome (ALGS) due to incomplete penetrance, phenotypic variability, and extensive genetic variation. Although disease-specific variant classification criteria have identified pathogenic hotspots within epidermal growth factor (EGF)-like repeats 8-12 and ankyrin repeat domains 3-6, characterizing these VUSs requires a robust framework. Methods: We reviewed aggregate deidentified data from 519 multigene cholestasis panel entries and evaluated genotype-phenotype data from a consortium cohort of 7 pediatric patients with heterozygous NOTCH2 VUSs using a clinical-genomic prioritization framework informed by disease-specific ACMG criteria and domain location. …

BACKGROUND: There are few prospective studies of mycophenolate mofetil (MMF) versus cyclophosphamide (CYC) for pediatric lupus nephritis (pLN) and none evaluating rituximab (RTX).

METHODS: The Prospective Pediatric Lupus Nephritis Registry (ProPeL-R) enrolled patients <  21 years within 4 weeks of an initial kidney biopsy diagnostic of pLN. Demographic, clinical, and laboratory data were collected prospectively at enrollment, 3 months, 6 months, and then every 6 months thereafter for up to 5 years of follow-up. For this study, we compared patients receiving initial therapy with corticosteroids (CS) and either MMF (n = 33) vs. CYC (n = 18), and those treated with CS, either MMF or CYC, with RTX (n = 20) vs. without RTX (n = 51).

RESULTS: Histology consisted of 18% class III; 35% class IV; 25% mixed class; and 22% pure class V. Eighty-two percent were female. No significant differences in response or infection rates were identified between those receiving MMF or CYC. There was a significant increase in combined complete (CR) and partial response (PR) at 24 months with RTX use. Overall CR rates at 6 and 24 months were 35% …

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.
