This study is for participants with tumors from pediatric cancers and genomic/molecular testing was done as part of standard of care treatment. This is an observational study; therefore, only information about the disease and medical treatment will be collected and participants will not receive any treatments or additional medications. The sponsor, Beat Childhood Cancer, will collect and store personal health information and molecular/genomic test results, tissue samples, and bodily fluids (examples: additional tube(s) of blood, urine, bone marrow or cerebral spinal fluid) that are left over after testing or treatment is completed in a data registry and a specimen bank, and make these available for future research. Database personnel will continue to collect and store participant information from future visits, as long as they do not withdraw from participation in this study.

The purpose of this research study is to develop a better understanding of the cause and natural history of vascular anomalies and related syndromes. This study is being done in order to develop a better understanding of the cause of vascular anomalies in order to to improve care for people who are affected by these anomalies and related syndromes.

This study is being done at the University of Wisconsin-Madison (UW-Madison) and other sites in North America and Europe. A total of about 1000 people will participate in this study. About 20 – 30 people will take part in the study here at the Medical University of South Carolina.

The purpose of this research study is to evaluate Parent Child Interaction Therapy (PCIT) delivered via tele-health for young children with a developmental diagnosis (ex. suspected or diagnosed autism, ADHD, global developmental delay, etc.) and disruptive behavior problems. Participants will go through a screening to determine eligibility. Once screening is complete, participants will complete a pre-therapy assessment in clinic, followed by 10 telehealth sessions one time per week, at no cost. Participants will then be asked to complete an in-person post-therapy assessment and follow-up questionnaires will be re-administered 3 months following the completion of therapy. Families will be compensated for their time.

The purpose of this research study is to evaluate Parent Child Interaction Therapy (PCIT) delivered via telehealth for young children with autism spectrum disorder (ASD) and disruptive behavior problems. Participants will go through a screening to determine eligibility. Eligible families who choose to participate will complete 3 in-person visits at MUSC and may receive 10 telehealth therapy sessions, at no cost. Families will be compensated for their time.

The Pediatric Intensive Care Influenza Study #2 (PICFLU2) is a multiyear, multicenter prospective observational study in patients aged ≤ 21 years hospitalized in pediatric Intensive Care Units (PICUs) and Stepdown (or intermediate) Care Units (SDUs) in the US designed to evaluate of the immunobiology of influenza virus-related critical illness in young hosts.

This study is for patients who have been diagnosed with relapsed or refractory CD22+ B-Acute Lymphoblastic Leukemia (B-ALL). The overall goal of this study is to find out what effect, good and/or bad, the drug inotuzumab ozogamicin has on children and young adults with relapsed or refractory B-ALL. Participants can expect to be on this study for up 2 months and followed for up to 5 years.

The purpose of this study is to see if taking mepolizumab is safe and effective in treating Hypereosinophilic syndrome (HES) in children and adolescent patients ages 6 to 17 years who are receiving standard of care (SoC) therapy. Mepolizumab is administered through a subcutaneous injection (shot). Participation in the study will last for about 64 weeks approximately (1 year and 3 months).

Constraint-induced movement therapy (CIMT) is the most efficacious treatment for children with hemiparesis from a perinatal arterial stroke but instead, weekly low-dose OT and/or PT is typical. The aims of this study are to compare 2 high doses of treatment to usual care in helping infants improve skills on the hemiplegic hand/arm and to improve bimanual activities. In addition, the association with gross motor, language and cognition will be explored.

In current practice, options for venous and lymphatic malformations remain limited. Recently an oral medication, sirolimus, has been found to benefit patients when taken once or twice a day for several months. Unfortunately there are many side effects associated with this medication, some of which can be severe including, neutropenia, oral ulcerations, and lab abnormalities. The purpose of this study is to determine if once weekly dosed sirolimus will be effective for the treatment of venous and lymphatic malformations. Additionally, the study will evaluate patient satisfaction and identify adverse effects. Participants will be on the medication for 6 months with an option to continue after this time period.

This study is for participants that have been diagnosed with a high-risk neuroblastoma that cannot be treated or did not improve with existing therapies, or the cancer came back after treatment with existing therapies. This study involves investigational drugs called 64Cu-SARTATE and 67Cu-SARTATE. The investigational drugs will be given as an IV injection. The study is divided into 2 parts: The Dose Escalation Phase and the Cohort Expansion Phase. The phase that participants will enroll to will depend on when they enter the study. The age range for participants is from 12 months to 25 years. Participants can expect to be in this study for approximately 14 months. Then followed by remote or virtual visits every 6 months for up to 36 months (3 years) after the initial dose of study therapy drug 67Cu-SARTATE.
