Prenatal Examination of Deletion 22q11 Syndrome : Thymic Dysgenesis THYMI Study
22q11 Deletion Syndrome Di George Syndrome22q11.2 microdeletion seems the prenatally under-diagnosed . Indeed , there is a mismatch between the series on the heart rate of 22q11.2 antenatal 84% against 30% in the adult series despite a perinatal mortality of 16% suggesting opportunities for improvement in the prenatal diagnosis of fetus with a microdeletion 22q11.2 , especially without heart disease
Molecular Genetics in Infantile Spasms
Infantile SpasmsWest SyndromeInfantile Spasms syndrome (ISs) is a characterized by epileptic spasms occurring in clusters with an onset in the first year of life. West syndrome represents a subset of ISs that associates spasms in clusters, a hypsarrhythmia EEG pattern and a developmental arrest or regression. Aetiology of ISs is widely heterogeneous including many genetic causes. Many patients, however, remain without etiological diagnosis, which is critical for prognostic purpose and genetic counselling. In the present study, the investigators performed genetic screening of 73 patients with different types of ISs by array-CGH and molecular analysis of 5 genes: CDKL5, STXBP1, KCNQ2, and GRIN2A, whose mutations cause different types of epileptic encephalopathies, including ISs, as well as MAGI2, which was suggested to be related to a subset of ISs.
Changes in the Hypotalamic-pituitary Region of Patients With Metabolic Syndrome and Obesity
Overweight and ObesityMetabolic SyndromeThis study aims to identify new morphological and quantitative magnetic imaging parameters of pituitary gland and sellar region in overweight and obese patient at baseline and after 3 years, dividing patients in 3 groups (weight loss through diet and lifestyle changes, weight loss through bariatric surgery, no weight loss)
Promising Bimarker Prediction of Outcome of HELLP Syndrome.
Pre-EclampsiaSevere2 moreHELLP syndrome is a life-threatening obstetric complication usually considered to be a variant or complication of pre-eclampsia. And may occasionally be confused with other diseases complicating pregnancy such as acute fatty liver of pregnancy, gastroenteritis, hepatitis, appendicitis, gallbladder disease, immune thrombocytopenia, lupus flare, antiphospholipid syndrome, hemolytic-uremic syndrome, thrombotic thrombocytopenic purpura, and nonalcoholic fatty liver disease. The distinction between thrombotic thrombocytopenic purpura-hemolytic uremic syndrome and severe preeclampsia is important for therapeutic and prognostic reasons. However, the clinical and histological features are so similar that establishing the correct diagnosis is often difficult; furthermore, these disorders may occur concurrently.
Metabolic Syndrome Feasibility Study
Metabolic SyndromeThe objective of this study is to determine whether the finger tip images captured by the EPIC ClearView device, when analyzed via the ClearView software, produce a Response Scale that characterizes trends consistent with Metabolic Syndrome identified by medical doctors.
Investigation of Psychometric Properties of the EuroQoL EQ-5D-5L in Patients With Carpal Tunnel...
Carpal Tunnel SyndromeThe purpose of this study is to determine how appropriate and practically is the EQ-5D questionnaire in use on patients with carpal tunnel syndrome undergoing surgery along the change of quality of life.
Developing Novel Microbiota-Targeted Therapies for Irritable Bowel Syndrome
Irritable Bowel SyndromeThis longitudinal study is being done to understand mechanisms underlying development of irritable bowel syndrome (IBS) and the role of the gut bacteria in development of symptoms. This information will be used to determine whether temporal changes in gut microbial taxonomy and metabolism are associated with changes in symptom severity in IBS, and if targeted dietary interventions, including prebiotics, can reverse or moderate these changes.
Brain Scintigraphy in Normal Versus Kleine-Levin Syndrome Subjects
Healthy SubjectsKleine-Levin SyndromeThe investigators perform neuropsychological tests and brain scintigraphy in 30 healthy subjects. These results will be compared with data obtained out of episode in patients with Kleine-Levin syndrome (KLS). The investigators want to determine if brain functional imaging and cognitive abnormalities persist during asymptomatic period in a large series of patients with KLS, and to find predictors of these abnormalities.
Epigenetics and Metabolic Disorders in Men With the Klinefelter Syndrome
Klinefelter SyndromeHypogonadismThis study will elucidate how the parental origin of the X-chromosome influences health status as well as metabolic fate in Klinefelter patients. Epigenetics and transcriptome-research will be directly linked to the metabolic and inflammatory pattern of actual patients to improve care for them. The Klinefelter Syndrome is one of the most common genetic disorders in men. The patients have one supernumerary X-chromosome, which is partly active and disturbs a normal male development. Testosterone deficiency in form of primary hypogonadism is a common feature in these men. Such a condition promotes clinically relevant metabolic patterns related to a pro-inflammatory status and diabetes mellitus type 2 (insulin resis-tance), cardiovascular disease as well as infertility. However, the variety of pathologies is pro-nounced between patients and low testosterone concentrations cannot fully explain the wide scope of pathologies in these men. Some patients become clinically obvious during puberty and adoles-cence, some in their thirties or later and all exhibit a huge variation in phenotype. Switching on and off of specific genes on the X-chromosome is differential, depending on the origin either from the maternal or paternal side. Hence, an influence on the clinical picture is hypothesised. Thus, key targets are clarification of the parental origin of the supernumerary X chromosome and elucidation of methylation and expression profile of pivotal X-chromosomal genes. These will be related to clinically relevant metabolic and inflammatory patterns as well as fertility to identify individual risks as well as treatment strategies for Klinefelter patients.
The Rolandic Epilepsy/ESES/Landau-Kleffner Syndrome and Correlation With Language Impairment Study...
Rolandic EpilepsyNocturnal Frontal Lobe Epilepsy2 moreIn clinical practice language impairment is frequently reported in association with nocturnal epileptiform activity. There is a spectrum of epileptic conditions that are characterized by nocturnal epileptiform activity. From mild to severe this spectrum involves: Rolandic epilepsy (RE), nocturnal frontal lobe epilepsy (NFLE), Landau-Kleffner syndrome (LKS) and electrical status epilepticus during slow wave sleep (ESES). The exact characteristic of the relationship between nocturnal epileptiform activity and language impairment is yet to be explored. The investigators suggest that nocturnal epileptiform EEG discharges and nocturnal epileptic seizures during development will cause diseased neuronal networks that involve language. The diseased neuronal networks are less efficient compared with normal neuronal networks. Objective: Identification of a diseased neuronal network characteristic in children with nocturnal epileptiform activity, which can explain language impairment in these children. For this the investigators will use functional magnetic resonance imaging (MRI) to analyse brain activity and diffusion weighted MRI to investigate white matter connectivity.
