Multicenter Prospective Cohort Study on Current Treatments of Legg-Calvé-Perthes Disease (IPSG1)

Legg-Calvé-Perthes disease is a childhood hip disorder which is common enough to be a significant public health problem (affects 1 in 740 boys between ages 0—14), but uncommon enough to have a sufficient number of patients from a single institution to perform a definitive prospective study comparing the results of current treatments. The present study will establish a database of prospectively identified patients with Legg-Calvé-Perthes (LCP) Disease and collect information regarding their presentation, treatment, and outcomes in the course of receiving currently available treatments. This study seeks to compare the outcomes of current treatments in the management of different age groups (ages 1-6, 6—8, 8—11, >11) of patients with Perthes disease at two- and five-year followup and at skeletal maturity. For each age group, two to three common treatment regimens currently used by practicing pediatric orthopaedic surgeons will be compared. The intervention a patient receives is determined through physician preference. Physicians pick an intervention for each age group and treat each patient with the same intervention.

G551D Observational Study- Expanded to Additional Genotypes and Extended for Long Therm Follow up (GOAL-e2) (GOAL- e2)

The goal of this research study is to collect blood and urine samples from people who have either the R117H type of CF or the non-G551D gating type of CF to be kept for future research.We will also use some of the collected blood to measure the number of neutrophils.

Healthy Sleep for Children With Down Syndrome (HELP-DS)

The purpose of this multi-center observational study (utilizing the sites enrolling patients for the Pediatric Adenotonsillectomy Trial for Snoring (PATS) [1U011HL125307-O1A1]) is to gather data regarding children with Down syndrome (DS) and Sleep Disordered Breathing (SDB) referred for treatment with adenotonsillectomy to inform a future randomized controlled trial in this population.

Inclusion Criteria:

• DS diagnosis regardless of genetic status (e.g., mosaicism or translocation).
• Aged >3 to <13 years at the date of consent.
• Primary indication for AT is nocturnal obstructive symptoms (i.e., not recurrent infections or other indications).
• Deemed to be a candidate for AT by Ear, Nose and Throat (ENT) evaluation; that is, no technical issues that would be a contraindication for surgery such as submucous cleft palate.
Exclusion Criteria:

• Prior tonsillectomy (partial or complete).
• Severe chronic health conditions that would contradict surgery (severe morbid obesity, unrepaired cyanotic congenital heart disease, bleeding disorders).
• Severe behavioral problems that would preclude participation in the study's testing procedures (PSG, actigraphy).
• Severe OSA with respiratory failure needing urgent/emergent management
• Plan to undergo additional airway surgery at the time of AT.
• Caregiver/child planning to move out of the area within 6 months.
• Caregiver/child does not speak English or Spanish well enough to complete the behavioral and performance measures.
• Child in foster care.

Red Blood Cell Exchange Transfusion as a Novel Treatment for GLUT1 Deficiency Syndrome

This proposal is an investigator-initiated, single-site proof of concept trial. Five patients will undergo isovolemic hemodilution-red cell exchange (IHD- RBCx) with up to 10 units of red cell antigens (Rh group, Kell, Duffy, Kidd blood group antigens) matched normal donor red cells to replace a target of 70% of the patient's red cells with donor red cells. The procedure will be performed as an outpatient according to protocols established for sickle cell anemia patients. One of the investigators is an expert on RBCx and will oversee the transfusion. Subjects will be assessed before and after transfusion, and at two months post transfusion. Outcome measures include neurological exam, electroencephalography (EEG), neuropsychological testing, and biochemical assays.

Diaphragmatic Hernia Research & Exploration, Advancing Molecular Science (DHREAMS)

The goal of this study is to identify genes that convey susceptibility to congenital diaphragmatic hernia in humans. The identification of such genes, and examination of their structure and function, will enable a delineation of molecular pathogenesis and, ultimately, prevention or treatment of congenital diaphragmatic hernia. There are many different possible modes of inheritance for congenital anomalies, including autosomal dominant, autosomal recessive, and multifactorial. Multi-factorial inheritance is responsible for many common medical disorders, including hypertension, myocardial infarction, diabetes and cancer. This type of inheritance pattern appears to involve environmental factors as well as a combination of genetic variations that together can predispose to or produce congenital anomalies, such as congenital diaphragmatic hernia. Our study is designed to establish a small, well-defined genetic resource consisting of 1) Nuclear families suitable for linkage analysis by parametric,non-parametric (e.g. sib pairs, TDT) and association techniques, 2) Individuals with congenital diaphragmatic hernia who can be directly screened for allelic variation in candidate genes, and 3) Individuals who can serve as controls (are unaffected by congenital diaphragmatic hernia). Neonates and their families will be collected from homogenous and heterogeneous populations. By characterizing diverse populations, it should be possible to increase the likelihood of demonstration of genetic variation in selected candidate genes that can then be used in association and linkage studies in individual subjects with congenital diaphragmatic hernia.
