Comprehensive Analysis Of The Retinal Cell Contributions To The Human Erg, Christopher W. Tyler

MODVIS Workshop

Purpose. Standard electroretinogram (ERG) protocols are largely designed to isolate the responses of the rod and cone retinal pathways, including the use of adapting backgrounds to suppress unwanted off-pathway responses. Here, we record spectral ERGs in the low-to-high mesopic sensitivity range in the absence of any adapting background in order to assess interactions between the pathways.

Methods. We have developed a comprehensive neuroanalytic model of the component structure of the ERG driven by knowledge of the underlying retinal physiology, to enhance its power as a critical diagnostic tool for a broad range of both retinal and systemic dysfunctions. The ERG …

Research Days

Background: Physiologically based pharmacokinetic models for simulating drug pharmacokinetics are useful to guide drug dosing for pediatric patients. Hepatic blood flow could be a useful variable to use in these models.

Objectives/Goal: In this study, we explored 2-D phase contrast non-invasive magnetic resonance imaging (MRI) to measure hepatic blood flow in children with and without obesity.

Methods/Design: In this IRB-approved study, we imaged pediatric patients with abdominal MRI with 2D phase contrast imaging of the descending aorta (AO) at the diaphragm, the inferior vena cava (IVC) at the right atrium, and inferior to hepatic drainage above the renal vein confluence …

Persistent Pediatric Breast Abscesses Following Initial Treatment At Tertiary And Community Centers, Derek Marlor, Kayla Briggs-Groves, Shai Stewart Md, Nelimar Cruz-Centeno, Charlene Dekonenko, Jason D. Fraser

Research Days

Introduction: Little data exist on the management of pediatric breast abscesses that fail initial treatment. Therefore, this study aimed to evaluate and report outcomes in these patients.

Methods: All patients <18-years-old treated for a breast abscess between January 2008 and December 2018 were included. Patients were divided into 2 groups: initial treatment at our institution (Group 1) and initial treatment at referring centers (Group 2). The primary outcome was disease persistence following treatment at our institution. Secondary outcomes included treatment modalities and patient characteristics.

Results: In total, 145 patients were identified: 111 in Group 1 and 34 in Group 2. Antibiotics alone were the initial treatment in 52.3% (n=58) of Group 1 patients and 64.7% (n=22) of Group 2 patients. Invasive treatment was more common in Group 1 (45.9% vs 5.8%; p<0.00001). Patients with persistent disease in Group 1 were treated with aspiration (n=7, 50%), I&D (n=5, 35.7%), antibiotics (n=1, 7.14%), and manual expression (n=1, 7.14%.), while Group 2 patients were treated with antibiotics (50%, n=17), aspiration (26.47%, n=9), I&D (17.65%, n=6), and manual expression (5.88%, n=2). Group 2 patients with persistent disease were more likely to be treated with antibiotics or a change in antibiotics (50% vs 7.14%; p=0.005). Following treatment at our institution, the rate of persistent disease was similar between groups (12.6% vs 11.8%).

Conclusions: Persistent breast abscesses may be treated with antibiotics in appropriate cases. Damage to the developing breast bud should be minimized. Disease …

Improvement On The Slopes: The Impact Of An Adaptive Snow Sports Program On Children And Young Adults With Disabilities, Stephanie Green, Mark T. Fisher, J Eichner, Matthew J. Mclaughlin

Research Days

Background: Adaptive downhill skiing has been described as a fun, safe, engaging recreational activity for those with disabilities (Sterba, 2006). There are numerous ways the alpine skiing can be modified to meet these athletes’ needs. For instance, athletes can use tethered skis, horizontal poles held by their instructors, or modified walkers. For those that have poor standing balance, or are non-ambulatory, sit-skis are an option, with or without outriggers to add additional support and balance for athletes with poor trunk stability or core strength. These options provide equal and accessible alternatives for those with disabilities to get out and enjoy …

Objectives/Goal: A 12-year-old male presented to Immunology clinic for DOCK8 deficiency. He was diagnosed in infancy due to diffuse papulopustular eruption positive for candidiasis and known family history. Past medical history included severe eczematous dermatitis, asthma, interstitial lung disease, food allergies, and poor growth, with cutaneous HSV and fungal infections, HSV keratitis, and MRSA bacteremia. Family history was notable for two siblings with DOCK8 deficiency, both deceased. …

Stewardship Opportunities For Cervical Lymphadenitis And Deep Neck Space Abscesses, Aaron Shaw, Brian R. Lee, Lauren Kazmaier, Emily Baker, Tina Dao, Sandra Arnold, Angela Myers

Research Days

Background: Cervical lymphadenitis (LAD) and deep neck space abscesses (DNSA) are common pediatric infections caused by similar bacteria. We sought to determine differences in presentation, diagnosis, and treatment between LAD and DNSA to identify antimicrobial and diagnostic stewardship opportunities.

Methods: Charts were obtained using ICD9/10 codes for retropharyngeal and parapharyngeal abscessed (DNSA), and LAD between 1/1/10-12/31/20 from two pediatric centers. 1981 charts were identified. Charts were excluded if the diagnosis was not a bacterial infection (e.g. Kawasaki disease), if the LAD was not in the neck, or if caused by less common bacteria (e.g. tuberculosis). Data on presenting signs, symptoms, …

The Effect Of A Lumbopelvic Compression Belt On Load Transfer During The Active Straight Leg Test: A Proof Of Concept Study Using Ultrasound Imaging, Shania D. Evans, Kelsey B. Hales, Elizabeth P. Lomax, Erin N. Roberts, Jalesa C. Wright, Elizabeth Chaffin, Ruth Maher

Research Day

INTRODUCTION: The active straight leg raise (ASLR) test assesses load transfer through the pelvis. During the ASLR, intraabdominal pressure (IAP) rises, increasing the load on the lumbopelvic region. Several studies have shown a correlation between the magnitude of bladder base displacement (BBD) during the ASLR and lumbopelvic instability. Additionally, greater depression of the bladder and pelvic floor muscles is associated with motor control impairments associated with form and force closure. Pelvic stability belts are a common therapeutic intervention for individuals who report pelvic girdle pain. Their mechanism of action is to improve form closure and assist force closure and motor …

Does The Use Of Vestibular Infrared Video Goggles Impact Physical Therapy Student’S Ability To Diagnose The Direction Of Nystagmus?, Erin Farmer, Tanna Mcpherson, Sabrina Samuels, Katherine Wellborn, Jeanne Welch

Research Day

INTRODUCTION:

Vestibular goggles are infrared video goggles that can improve patient care by providing accurate assessment and treatment of vertigo, dizziness, and feelings of imbalance. These goggles track the eye movement allowing clinicians to evaluate the function of the vestibular system, which controls balance and spatial coordination. During an evaluation, the patient wears the infrared goggle while performing a series of movements designed to stimulate the vestibular system. The embedded infrared cameras capture eye motion, providing real time information to the clinician. Physical therapists (PT) need to be able to detect nystagmus and its direction in order to provide appropriate …

2000-2020 Nhis Studies: Factors Affecting Medication Adherence Rate In The Pediatric Population With Medical Complexity, Janice Tong, Savion Carswell, Erica Wong, Xinyu Wang, Yujin Kim

Research Day

Introduction

Children with medical complexity belong to a vulnerable patient population group that is defined by the interplay of chronic health conditions, high healthcare utilization, and severe limitations in cognitive and/or physical functioning. Members of this patient population often require a complex management and/or treatment regimen with the use of more than one medication. Pediatric nonadherence in medication can lead to increases in microbial resistance, adverse drug reactions, morbidity, and mortality. The consequences of this medication nonadherence may also cause slower recovery times, increased number of emergency department visits, and hospitalizations, which subsequently substantiates higher medical costs for families along …

A Seemingly Low Risk Patient Develops Urosepsis As A Complication Of Transrectal Prostate Biopsy: A Case Study, Nicole Peritz, Gabrielle Oquendo, Yuhyun Kang, Elijah Humphries, Joy Zarandy

Research Day

Background:

Prostate cancer (PCa) is the most common cancer in men, and the second most common cause of cancer deaths in the United States. Approximately 1 million Americans undergo prostate biopsies annually, with 97% undergoing the transrectal prostate biopsy (TRPB). While TRPB is reliable and relatively low risk, nearly 7% of patients develop infectious complications, with 3% requiring hospitalization due to sepsis. Risk factors for developing infection post-TRPB include antibiotic resistance, >10 biopsy cores, diabetes mellitus, indwelling catheter, and African-American ethnicity. Identifying risk factors, considering a transperineal biopsy approach, and utilizing pre-procedural practices like rectal sterilization, screening urinalysis, prophylactic antibiotics, …
