Long-Term Outcomes And Satisfaction Rates After Costal Cartilage Resection For Slipping Rib Syndrome, James Fraser

Research Days

Background/Objectives/Goal: Slipping rib syndrome (SRS) is a challenging and underdiagnosed condition that has proven to be an elusive diagnosis due to an extensive differential with presenting symptoms that mimic a myriad of alternative diagnoses of both thoracic and abdominal pathology. The diagnosis of SRS is recognized in a patient with consistent, progressive, often debilitating unilateral or bilateral chest wall and/or upper abdominal pain with intermittent clicking or rib slipping. SRS frequently does not resolve with conservative management, including physical therapy, rest, and NSAIDs, as well as intercostal injections, and even opioid medications. Workup can be extensive including multiple subspecialty referrals …

Multimodal Pain Control In Common Neonatal Surgeries: Post-Operative Pain Protocol Reduces Opiate Exposure And Side Effects, Jamesia Donato

Research Days

Background: Opioids are the primary post-operative (post-op) analgesic in neonates. Side effects include hypotension, apnea and ileus. Previous studies show IV acetaminophen decreases opiate need in specific populations including cleft palate repair, cardiac surgery. The effect of IV acetaminophen as part of a post-op pain algorithm is not known in common neonatal surgical procedures.

Objectives/Goal: To determine if (a) a post-op pain algorithm including IV acetaminophen and (b) IV acetaminophen exposure reduces cumulative opioid requirements in neonates undergoing common surgeries in the NICU.

Methods/Design: This is a retrospective cohort study comparing cumulative post-operative opiate exposure between infants with common surgeries …

Improving Thromboprophylaxis In Hospitalized Pediatric Inflammatory Bowel Disease Patients- A Quality Improvement Project, Amy Issa, Panam Kaur

Research Days

Background/Project Intent (Aim Statement): Pediatric inflammatory bowel disease (IBD) patients in acute flare have 1.5 to 3-fold higher risk of thromboembolism compared to the general population. Anticoagulation therapy is recommended for pediatric IBD patients who have ≥ 1 risk factors for venous thromboembolic events. At Children’s Mercy Hospital (CMH), approximately 80 patients/year are admitted for acute flare, of which, roughly 30% receive appropriate thromboprophylaxis. Lack of standardization of thromboprophylaxis and an educational gap amongst providers are significant barriers. Our goal is to standardize and improve the rates of thromboprophylaxis in IBD patients admitted at CMH from 30% to 60% by …

Umbilical Access In Laparoscopic Surgery In Infants Less Than 3 Months: Single Institution Retrospective Review, James Fraser

Research Days

Background/Objectives/Goal: Umbilical access in laparoscopic surgery has been cited as a potential factor for increased complications in low-birth-weight infants and those less than three months old. Previous series noted a self-reported complication rate of 10.6% among 329 pediatric surgeons via anonymous survey, citing carbon dioxide (CO2) embolism as the most common complication. We report four-year outcomes with blunt transumbilical laparoscopic access to examine the safety of this technique.

Methods/Design: Following IRB approval, a retrospective database of patients less than three months of age who underwent laparoscopic pyloromyotomy or inguinal hernia repair from 2016-2019 at a tertiary care academic center was …

Case: A 55-year-old male with history of a patent foramen ovale, atrial fibrillation and embolic stroke presented with worsening fatigue and dyspnea at rest. Echocardiogram showed mildly reduced ventricular function with severe right heart dilation. On transesophageal echo, the coronary sinus (CS) was severely dilated with a persistent left superior vena cava (LSVC). A stress test showed no perfusion defects. CT angiography showed an absence of right SVC and a single LSVC connecting to the CS. There was …

Congenital Mitral Valve Regurgitation, The Dilemma Of Repair Vs Replacement., Bianca Cherestal

Research Days

Background: Congenital mitral regurgitation is a rare condition and can be challenging to manage when presenting in the neonatal period

Objectives/Goal: Two week old male presented with poor weight gain, murmur and cardiomegaly on chest X-ray. Echocardiogram showed moderate to severe mitral regurgitation (MR) and suprasystemic pulmonary hypertension (PHN) (fig 1 a, b). The mitral valve (MV) leaflets were thickened and tethered with failure of central coaptation. PHN was classified as WHO I and II (due to persistent PHN of newborn and MR respectively). Inhaled nitric oxide, Enalapril and Furosemide were initiated. Cardiac catheterization revealed PVRi of 8.9 WU x …

The Impact Of Early Tracheostomy On Neurodevelopmental Outcome Of Infants With Severe Bronchopulmonary Dysplasia Exposed To Postnatal Steroids, Amjad Taha

Research Days

Background: BPD is associated with long-term neurodevelopmental impairment. Tracheostomy is performed in 5-12% of severe BPD for prolonged ventilation. There is evidence that chronic ventilation with tracheostomy in severe BPD may facilitate neurodevelopment and lead to improved outcome. However, there is no consensus on the optimal timing of tracheostomy. A large multicenter study of infants with tracheostomy performed at <120 days of life had better neurodevelopmental outcomes at 18-22 months of age. Use of steroids postnatally to ameliorate the severity of BPD had been controversial due to its negative effect on neurodevelopment. To date, no data has specifically evaluated the impact of early tracheostomy on neurodevelopmental outcome of infants with severe BPD who are exposed to postnatal steroids.

Objectives/Goal: To compare the cognitive, language and motor scores among 3 groups of severe BPD infants who received early vs late vs no tracheostomy. Secondly, evaluate if postnatal steroids had an additive negative effect on neurodevelopmental outcomes.

Methods/Design: IRB approved retrospective …

Constrictive Pericarditis After Repair Of A Ruptured Sinus Of Valsalva, Sarah Studyvin, Laura Kuzava

Research Days

Background: Constrictive pericarditis is an uncommon complication of cardiac surgery. We report a patient who developed constrictive pericarditis after ruptured sinus of Valsalva (RSOV) repair.

Methods: A 23-year-old male presented with exertional dyspnea one year after RSOV repair. TTE showed a small, circumferential effusion with thickened pericardium, ventricular septal bounce, left atrial enlargement, diastolic hepatic flow reversal, and trivial mitral regurgitation without stenosis. He underwent cardiac catheterization, which revealed elevated filling pressures (RVEDP 16 mmHg, LVEDP 18 mmHg), RVEDP/RVSP ratio < 0.5, and a low cardiac index (1.65 L/min/m2). Cardiac MRI confirmed pericardial thickening with paradoxic septal motion, dilated pulmonary veins and retrograde flow in the SVC.

Results: Pericardiectomy of thickened and adherent pericardium was performed. The central venous pressure decreased from 23 to 7 mmHg and …

Simulation Based Clinical Systems Testing Of A Pediatric Ed To Improve Staff And Process Readiness For Pediatric Hypoglycemia, Kevin Meilak Md

Research Days

Background/Project Intent (Aim Statement): Hypoglycemia is the most common metabolic disorder in children in pediatric emergency department (ED) settings 1 . Children may present with nonspecific symptoms, or asymptomatically2 . So identification/treatment is very challenging. There is evidence in the adult literature that there is wide variability in the treatment of hypoglycemia3 . Currently Children’s Mercy does not have a standardized approach to the treatment of hypoglycemia not associated with diabetes mellitus. From observation in the clinical setting we believe there are gaps regarding the identification and treatment of hypoglycemia not associated with diabetes mellitus. Delayed recognition and under treatment …

Optimization Of Perioperative Prophylaxis In Penicillin-Allergic Labeled Patients, Katie A. Vandervelde

Research Days

Problem Statement/Question: A penicillin (PCN)-allergy label is life-long and has been shown to result in more costly, less effective, and broader-spectrum antibiotics being utilized for surgical prophylaxis. At CMH, 6.6% of surgical patients receiving perioperative antibiotics are labeled PCN-allergic. A common myth is that approximately 10% of patients with a PCN-allergy history will experience an allergic reaction if administered a cephalosporin, whereas recent observational studies have found crossreactivity rates between 0.17-0.7%. Most of these patients receive a cefazolin alternative unnecessarily. Currently, no process exists to identify and clarify PCN-allergic patients preoperatively. Data from November 2018-December 2019 found ~2.33 patients per …

A Case Of Metabolic Genetic Emergency, Elizabeth Loughman

Research Days

Background: Newborn screening (NBS) is one of the largest public health initiatives to improve infant morbidity and mortality, and this has been shown to detect and lead to prompt treatment of uncommon but rapidly fatal conditions. While NBS has changed outcomes of diseases, it is still imperative that prompt and early recognition of abnormal results and medical interventions remain the mainstay of care.

Objective: To describe a case of inborn error of metabolism in a 4-day old asymptomatic infant, where early recognition and treatment affected outcome.

Design/Methods: This case is a 4-day old female, former 36-week gestational age infant who …

Association Between Blood Pressure And Esa Dose In Pediatric Patients On Dialysis, Heather A. Morgans

Research Days

Background: Hypertension is a reported side effect of Erythropoiesis Stimulating Agents (ESAs), with a mechanism of action related to elevated hematocrit levels and direct vasopressor effects. Limited information exists on the relationship between ESA dosage and hypertension in children receiving maintenance dialysis.

Objectives/Goal: The primary aim of this study was to determine whether there is a significant association between ESA dose and blood pressure (BP) in pediatric patients on dialysis. The secondary aim was to determine covariates in relation to ESA dose.

Methods/Design: Data from the International Pediatric Dialysis Network (IPDN) database was used to retrospectively analyze the association between …

Bivalirudin And Thrombolytic Therapy: A Novel Successful Treatment Of Severe Aortic Arch Thrombosis In A Term Neonate, Amjad Taha

Research Days

SUMMARY An early term infant with uncomplicated perinatal history was found to have a large thrombus in the aortic arch after he failed regular newborn critical congenital heart defect (CCHD) screen. He responded well to Bivalirudin thrombolytic and tissue-Plasminogen activator (tPA) combination therapy, with a significant resolution of the thrombus. The infant tolerated hospital admission well with no significant complications. He was discharged home on daily aspirin at two weeks of life. To our knowledge, the combination therapy approach with Bivalirudin and tPA is the first one reported in the literature in the neonatal age group.

BACKGROUND Aortic arch thrombosis …

Functional Outcomes Of Infants With Chiari Ii Malformation With Tracheostomy And Home Ventilator Dependence, Abbigayle Carlson

Research Days

Background: Chiari II malformation is relatively common with an incidence of about 1 in 1000 live birth and is associated with reduced life expectancy. Characteristic features are beaked midbrain, downward displacement of the tonsils, and cerebellar vermis, and spinal myelomeningocele that can be associated with hydrocephalus needing ventriculoperitoneal shunt (VP shunt). Mortality is about 50-70% if not recognized early. Survivors have high morbidity and develop neurologic abnormalities and significant developmental delays. Long-term outcome is poorly understood.

Objective: Not much has been published that describes the outcome of infant with Chiari II malformation that received tracheostomy for long-term ventilator support. Our …

Diagnosis And Management Of Otitis Media With Effusion In Pediatric Urgent Care Clinics, Ashley Deschepper

Research Days

Background: Otitis media with effusion (OME)’s clinical presentation is often confused with acute otitis media (AOM) by providers. Despite OME guidelines recommending watchful waiting with no antibiotics, rates of antibiotic use remain elevated. In our pediatric urgent care clinics (UCCs), an estimated 50% of patients diagnosed with OME receive antibiotic prescriptions.

Objectives/Goal: To determine the provider diagnosis validity and the rates of antibiotics prescribed among pediatric OME patients evaluated in 3 UCCs within a pediatric healthcare system.

Methods/Design: We randomly selected 75% of encounters for children age 0-18 years who had a billing diagnosis of OME in 2019. Charts were …

Evaluation Of A Symptom-Based Algorithm For Managing Battery Ingestions In Children, James Fraser

Research Days

Background/Objectives/Goal: Complications from battery ingestion in the pediatric population are becoming more severe due to the emergence of stronger and smaller batteries. We previously established a symptom-focused, evidence-based algorithm for battery ingestion and seek to evaluate this protocol to investigate its safety and potential cost benefit. (Figure 1)

Methods/Design: Following IRB approval, all radiographs performed for foreign body ingestion between 2017-2020 were reviewed. All button battery ingestions were included to evaluate an institutional symptom-based algorithm emphasizing observation over intervention.

Results: Review of 2,237 foreign bodies series demonstrated 44 button battery ingestions. Median age at ingestion was 3.8 years [2.5,5.2]. Locations …

Phenotypic Characterization Of Jarid2-Related Intellectual Disability: A Case Series, Maxime Cadieux-Dion

Research Days

Background: In recent years, wide implementation of research and clinical next generation sequencing has led to an astonishing number of novel disease-gene assertions. Recently, loss of function variants in JARID2 were reported in 16 patients with a clinically distinct neurodevelopmental phenotype that consisted of neurodevelopmental delay, intellectual disability (ID), learning disability, autism and behavioral abnormalities. Dysmorphic features were seen in most patients and included high anterior hairline, deep-set eyes, full lips, broad forehead, bulbous nasal tip, or depressed nasal bridge. Cleft lip/palate was observed in only 1/16 patients. Most cases were de novo, with only one inherited case from an …
