Lactate Levels During Cardiopulmonary Bypass in Pediatric Patients
Heart DefectsCongenitalMany variables measured in critically ill patients have been used to estimate severity of disease, prognosticate morbidity and mortality, evaluate costs of treatment, and finally indicate specific treatment and monitor the adequacy of treatment and its timing. It is unlikely that one measurement can replace all of these, but in the remainder of this manuscript the investigators will show that lactate levels may come close. Although in our mind strongly linked to tissue hypoxia, lactate levels follow many more metabolic processes not related to tissue hypoxia and, therefore, subject to many disturbances found in various clinical situations

Apparently Balanced Chromosomal Translocation/ Next-generation Sequencing/ Intellectual Disability...
Intellectual DisabilityCongenital AbnormalitiesApparently balanced chromosomal rearrangement (ABCR) associated with an abnormal phenotype is a rare but problematic event. It occurs in 6% of de novo reciprocal translocations and 9% of de novo inversions. Abnormal phenotype, including intellectual disability and / or multiple congenital anomalies (ID/MCA) may be explained either by associated cryptic genomic imbalances detectable by array-CGH or by gene disruption at the breakpoint. However, breakpoint cloning using conventional methods (i.e., fluorescent in situ hybridization (FISH), Southern blot) is often laborious and time consuming and cannot be performed routinely. Without complete investigation of these rearrangements, genetic counseling is a real challenge. Recently, the investigators and others showed that Next-Generation Sequencing (NGS) is a powerful and rapid technique to characterize ABCR breakpoints at the molecular level. The ANI project (ABCR NGS ID) aims at characterizing at the molecular level ABCR in 55 patients presenting with intellectual disability and/or multiple congenital anomalies (ID/MCA) using NGS. The investigators make the hypothesis that ABCR account for the patient phenotype, either by gene disruption or position effect, since genomic imbalance would have been previously excluded by array-Comparative Genomic Hybridization (CGH). The ANI project is a 3-year-long study that will be conducted by a consortium of 21 partners, including 19 french hospital cytogenetics laboratories, a research team (TIGER), and a cellular biotechnology center. Patients will be recruited by each Cytogenetics laboratory. ABCR breakpoints will be molecularly characterized by NGS and a first bio-informatics analysis. The results will be verified by amplification of junction fragments by polymerase Chain Reaction (PCR) followed by Sanger sequencing, allowing the localization of breakpoints at the base-pair level. In some complex cases, FISH experiment will be necessary to clarify the results. A second bio-informatics analysis will then determine breakpoints' characteristics (sequence, repeated elements, gene and regulatory elements). Finally, for each breakpoint, gene expression studies will be performed including the gene disrupted by the breakpoint and two neighboring genes. All these data, together with those already available in the literature and databases will be integrated to determine if the gene could account for the patient's phenotype, allowing an appropriate genetic counseling. This project will identify new candidate genes involved in ID and developmental anomalies. It will also contribute to the development and evaluation of NGS as a diagnostic tool for ABCR and ID/MCA. It will also allow unraveling mechanisms and functional consequences of ABCR, in particular in term of position effect. In conclusion, the ANI project will contribute to the improvement of diagnostic management and genetic counseling of patients with ID/MCA and ABCR. It will also contribute to the understanding of ABCR physiopathology and to the unraveling of pathway involved in development and brain function, thus improving genetic counseling for ID/MCA patients in general.

Airway Vascular Lesions
HemangiomasVenous Malformations1 moreControversy exists in the treatment of airway hemangiomas ranging from tracheotomy, various lasers, to open removal, none of which have proven to be a gold standard. Venous malformations of the airway are difficult to treat and also require laser therapy or open removal and often repeated treatments are required. Similarly airway lymphatic malformations can require multiple treatment modalities as well as multiple procedures and are infrequently eradicated when extensive. New uses for various lasers and differing treatment protocols are frequently developed. Review of the treatment modalities and efficacy of these methods is required. The goal of this research is to determine protocols for treatment of airway vascular malformation and to evaluate our results from treatment of these lesions.

Reproduction and Survival After Cardiac Defect Repair
Cardiovascular DiseasesHeart Diseases14 moreTo create a registry of all Oregon children undergoing surgical repair of congenital heart disease since 1958 in order to determine mortality, morbidity, and disability after surgery and to assess the safety of pregnancy in women with corrected congenital heart disease and the risk of prematurity and occurrence of congenital heart defects in offspring.

The SALMANTICOR Study
Structural Heart AbnormalityThe SALMANTICOR study will obtain data on the prevalence and incidence of structural heart disease in a population setting. A cross-section survey of randomly selected residents of Salamanca (Spain) will be performed. A total of approximately 2400 individuals, stratifies by place of residence (rural and urban) and by age and sex will be studied. The variables to analyzed will be obtained from the clinical history, different surveys including social status, Mediterranean diet, functional capacity, electrocardiogram, echocardiogram and biochemical and genetic analysis. Surviving participants are expected to return for a 5 and 10-year follow-up visit.

International Cohort Study of Children Born to Women Infected With Zika Virus During Pregnancy
ZikaNeurodevelopmental Abnormality3 moreThe International Cohort Study of Children Born to Women Infected with Zika Virus (ZIKV) During Pregnancy study is a prospective, observational, international cohort study of children previously enrolled in the ZIP study or other ZIP 2.0 Protocol Team approved ZIKV-cohort study that will continue the longitudinal follow-up of children born with documented confirmed or presumptive in-utero ZIKV exposure ("ZIKV-exposed" cohort) and children born without documented confirmed or presumptive in-utero ZIKV exposure, matched by site and birth sex ("ZIKV-unexposed" cohort). Follow-up evaluations and assessments will allow for the determination and comparison of long-term neurodevelopmental outcomes among in utero ZIKV-exposed and ZIKV-unexposed children. Each participant will be followed for about 2 years, beginning at approximately 18 months through 42 months of age.

Retrospective Evaluation of GGPSP's Safety and Clinical Performance for the Treatment of Lower Limbs...
Genu VarumGenu Valgum7 moreOrthofix is conducting this retrospective Post-market clinical follow up (PMCF) study to assess the safety and clinical performance of the GGPSP device, which is a new version of the Guided Growth Plate System (GGPS) from which it differs for small modifications compared to the original design. The purpose of the study is to collect clinical evidence from the use of the device in a representative number of pediatric patients who have already been treated with the device in the study and with at least one control visit post removal of plaque.. For this purpose, a retrospective PMCF study was considered to be the most appropriate study design to obtain the necessary information.
