Craniofacial Differences And Safe Sleep Practices: Findings From A Caregiver Survey At A Children’S Hospital, Cait Vuturo-Brady, Aracelia S. Aldrete, Jesus Gil Inciong, Miccah Seaman, Rianna Leazer

Knowledge and Creativity Expo

Purpose

Many infants with cleft lip and/or palate (CL/P) have airway issues that make supine, flat-surface sleep challenging.1 Prior studies indicate that alternative positioning may reduce obstructive events,2 and early sleep-disordered breathing can affect later development.3  Despite this, caregivers of infants with craniofacial differences rarely receive tailored sleep guidance, and no evidence-based, condition-specific recommendations currently exist.4,5

Methods

This single-site, cross-sectional study evaluated sleep practices, caregiver education, and barriers to adherence among parents of children (< 3 years) with CL/P treated at CHKD’s Craniofacial Program. Eligible caregivers (n=117) were identified via query of the electronic medical record by CHKD Data Governance and invited to complete an anonymous REDCap survey assessing demographics, sleep environment, counseling, and understanding of safe-sleep recommendations.

Results & Conclusions

Of the 11 caregivers who completed the survey, 91% reported crib sleep, though several also used beds, couches, …

Toward Electrical Impedance Sensing Surgical Drill For Tissue Boundary Detection, Harshavardhan Devaraj Apr 2024

Toward Electrical Impedance Sensing Surgical Drill For Tissue Boundary Detection, Harshavardhan Devaraj

Dartmouth College Ph.D Dissertations

Dental implantation is an increasingly common procedure used to treat missing teeth. However, surgical drilling to place the implant poses a high risk of injury to critical anatomy, such as inferior alveolar nerve injury or maxillary sinus perforation. A real-time surgical feedback system sensing proximity of these critical anatomy could reduce injury risks. This dissertation investigates the development of such a system that incorporates an electrical impedance sensor into the tip of a surgical drill.

A simulation framework based on finite element method (FEM) was developed to optimize the sensor as it approached a high impedance boundary. The accuracy of …

Sarcoidosis Of The Mandibular Condyle: A Rare Disease That Can Mimic Malignancy, Chad Sloan, Ben Lacrosse, Lei Yu, Alexander Braun, Scott Lauer, Timothy Donovan, John Baker, Jason Untrauer

Graduate Medical Education Research Journal

Sarcoidosis can involve any of the organs, however intraosseous involvement is rare and ranges from 5 to 15%, with lesions of the mandible being even rarer – currently with few known cases reported. Intraosseous lesions involving the mandible have been noted to be asymptomatic or associated with chronic jaw pain. Additionally, mandibular involvement can present as a lytic bone lesion mimicking osseous malignancy. Chronic polyarthritis is commonly associated with the progression of sarcoidosis and intraosseous involvement has been considered a late-stage sequelae. We report a case of biopsy-proven sarcoidosis within the mandibular condyle in an asymptomatic 56-year-old Caucasian female who …
