Cost Effectiveness Of Sending Of Routine Collection Of Sinus Contents In Skull-Base Patients, Jonathan Grey, Caroline Roberts, Amanda Bachand, Jacob Keeley, Adam Folbe

Posters

• Following endoscopic skull-base surgeries, it is common practice to send sinus contents for histopathological review and examination, in addition to the tumor/pathology itself.
• Histologic analysis of standard surgical specimens has long been thought to enhance diagnostic precision, ensure quality control, and offer procedural documentation.1 However, with rising healthcare costs, the necessity of this practice has been challenged in specific situations, such as this one.1
• In this study, we sought to determine if the regular collection of sinus contents uncovers another disease process or informs clinical decision-making.
• We also determined the cost of routinely sending sinus contents to pathology for evaluation. …

Custom Gene Panel Sequencing Of Fevr Patients And Family Members, Rima Stepanian, Gabrielle Abdelmessih, Kim Drenser, Antonio Capone Jr, Michael T. Trese, Wendy Dailey, Ken Mitton

Posters

Familial exudative vitreoretinopathy, or FEVR, defines a group of inherited retinal diseases marked by abnormal blood vessel growth in the retina, causing poor vascular development in the peripheral retina. It is linked to increased vessel permeability and may result in retinal ischemia, exudative retinal detachment, and subsequent vision loss. It can be inherited through autosomal dominant, autosomal recessive, or X-linked recessive patterns. There is no definitive treatment or cure, but is treated based on staging of disease on an individual case-by-case basis. Genomics is a rapidly growing field in personalized medicine. Targeted next-generation sequencing (NGS) enables fast and cost-effective identification …

A Unilateral Myopic Shift Secondary To Sturge-Weber Syndrome Results In Refractive Amblyopia Of The Fellow Eye In A Pediatric Patient, Mckenzie Stewart, Christina Twardowski

Posters

A 4-year-old patient with unilateral glaucoma secondary to Sturge-Weber Syndrome causes a myopic shift. The fellow healthy eye maintains high hyperopia resulting in anisometropic refractive amblyopia, requiring occlusion therapy. It is well documented that a glaucomatous high IOP causes an expansion of the globe due to excessive plasticity of collagen fibers in pediatric eyes. The elongated axial length induces myopic shifts. In this patient, the myopic shift in her glaucomatous eye resulted in a unilateral high hyperopic refractive error in the fellow eye with normal ocular health. This anisometropia is enough to cause amblyopia in the hyperopic eye. In past …

Molecular Characterization Of Kif11 Variants In Familial Exudative Vitreoretinopathy, Konstantinos Koustas, Kenneth P. Mitton, Wendy Dailey, Kimberly A. Drenser

Posters

Pediatric retinal diseases including Familial exudative vitreoretinopathy (FEVR) and Norrie Disease are linked to mutations in Wnt signaling network genes like FZD4, LRP5, TSPAN12, and NDP (see Figure-1). Active Norrin signaling is crucial for the normal growth and proliferation of developing retinal vasculature. Similarly, the absence of KIF11's kinesin activity can hinder the growth and proliferation of retinal vasculature, leading to peripheral avascular neural retina. According to the UniProt database there are about 41 disease causing variants for KIF11, and 17 specifically associated with FEVR. Nextgeneration sequencing was employed to sequence 76 subjects, aiming to identify novel variants to broaden …

Postmastectomy radiation therapy (PMRT) utilized as part of a breast cancer treatment regimen reduces the risk of disease recurrence in appropriately selected patients.1,2,3,4,5 However, PMRT increases risk of radiationrelated toxicities that can interfere with breast reconstruction post-mastectomy.6 Following mastectomy, implant-based reconstruction can increase patient satisfaction and quality of life7,8; complications induced by PMRT such as infection and tissue contracture, though, increase risk for implant loss and may ultimately require further surgeries for the patient.

PMRT is delivered based on treatment plans that are optimized to provide appropriate radiation dosages to tissues along the chest wall while simultaneously limiting exposure of …

A Novel Targeted-Sequencing Panel To Detect Lrp5 Gene Variants In Orphan Pediatric Retinal Diseases, Daeun Jeong, Kenneth P. Mitton, Kimberly A. Drenser

Posters

Orphan pediatric retinal diseases which encompass Familial exudative vitreoretinopathy (FEVR), Norrie Disease, and Retinoschisis are associated with mutations in genes involved in the Wnt signaling network, including FZD4, LRP5, TSPAN12, and NDP. See figure-1. FEVR is a retinal disease that lacks normal vascularization and angiogenesis to the peripheral retina. LRP5 variants account for 10-25% of cases of autosomal dominant FEVR. However, not all cases have been linked to these existing variants. Next generation sequencing was used to sequence 76 subjects for novel variants to expand the spectrum of LRP5 variants and better understand the mechanism of pathogenicity.
