This study is for patients that have been diagnosed with relapsed/refractory neuroblastoma. The investigational drug given is eflornithine (DFMO) along with etoposide. DFMO is the investigational drug being used along with etoposide for treatment of neuroblastoma. Participants will undergo a number of standard tests and research-related procedures before being able to enroll in this study. Some risks include but are not limited to: fewer red and white blood cells, diarrhea, abdominal pain, loss of appetite, skin rash, seizure, difficulty swallowing and blurred vision. Participants can expect to be on this study for approximately 2 years. Participants will then be followed for up to 5 years after study completion.

This is an OLE study for subjects completing from one of two double-blind clinical
trials. Subjects must have completed the Week 13 visit from one of these two parent
clinical trials to be eligible for this OLE.

The purpose of this study is to find out whether a web-based intervention using a mobile app is helpful for teens and young adults with sickle cell disease (SCD) in learning how to care for and manage their symptoms. 300 teens and adults with SCD will be enrolled in this study which is being conducted at the Medical University of South Carolina in Charleston SC., East Carolina University in Greenville NC., University of Miami in Miami FL., and the University of Alabama in Birmingham AL.

This is a global, Phase 3b/4, randomized, open-label, efficacy assessor-blinded, multi-center study that will evaluate upadacitinib compared with dupilumab, as monotherapy, in adolescents and adult subjects who have inadequate response to systemic therapy. The study will consist of a 35-day Screening Period; Period 1, a 16-week randomized, open-label, efficacy assessor blinded treatment period for all subjects, and a 30-day or 12-week follow-up visit for subjects on upadacitinib and dupilumab respectively, who will not enter the Period 2; Period 2, a 16-week open-label, efficacy assessor blinded extension period for those subjects with a < EASI 75 response at Week 16 (total duration 32 weeks) and a 30-day follow-up visit.

This study wants to understand how we can better identify children who have experienced or are at risk to experience child maltreatment. We will be interviewing caregivers of children and primary care providers (nurses, pediatricians, social workers) to understand their perspectives on screening for child safety risks in primary care settings. Interviews with providers will also focus on their feedback on a new tool to designed to detect child safety risks within health care settings. Findings will help inform best practice in integrated health care settings.

The purpose of this study is to evaluate the findings of Abdominal Ultrasound (AU) and to determine the effectiveness and safety in diagnosing Inflammatory Bowel Disease (IBD) in children. An AU provides a cost-effective, radiation-free, noninvasive method while a colonoscopy, endoscopy, and biopsy are invasive procedures. A secondary aim of the study is to compare the AU findings with blood markers and advanced imaging, when available. The department of Radiology will be conducting this study at the Shaw Jenkins Children's Hospital and MUSC Children's Health R. Keith Summey Medical Pavilion.

This study aims to evaluate the efficacy and safety of lebrikizumab when used in combination with topical corticosteroid (TCS) treatment, compared with placebo, in pediatric participants with moderate-to-severe atopic dermatitis. Participants found to be eligible according to all of the study entry criteria will be randomly assigned in a 2:1 ratio to receive either lebrikizumab or placebo. This study can last up to 32 weeks, with 4 study periods. Screening Period: up to 4 weeks (≤30 days), TCS Standardization Period: 2 weeks, Treatment Period: 16 weeks, Post-Treatment Safety Follow-up Period: 12 weeks.

This is a low-interventional cohort study to determine cardiac and non-cardiac long-term outcomes of persons <21 years of age with myocarditis/pericarditis after the administration of COMIRNATY, compared with similarly aged persons with myocarditis/pericarditis associated with COVID-19, including MIS-C.

This study explores the best way to teach two-year-old toddlers new verbs, and whether there are differences in what is best between late talkers and typically developing children. In a series of two, one-hour visits, children will watch videos on an eye-tracker, which will capture their face and gaze patterns. This data will be analyzed to see how children are making sense of what they are hearing. In one task, we ask whether it is better for children to hear a new verb before they see the action it denotes, or whether it is better to see the new action before hearing the verb. In the second task, we consider how quickly children are able to make sense of the language they hear, and whether this has any relationship to how they learn new verbs (Task 1). Results will help shape new clinical interventions for late talkers.

The purpose of this study is to learn how well a new mobile app helps families manage their child's nephrotic syndrome. We will be asking what parents think of the new app and how we can improve the design of the app. We will look for 60 parents to participate in the study, from 4 children's kidney clinics in the United States. The study will last 12 months. Participants will be asked to check their child's urine protein levels at home daily and answer surveys. If participants are randomly assigned to the mobile app study arm, they will be asked to use the app. The risks associated with participating in this study include loss of privacy and breach of confidentiality. There are no anticipated benefits to your child from participating in the study, but we hope that in the future the app will help families manage nephrotic syndrome. The alternative is to not participate in this study. Participants will be compensated for their participation in the study.
