View clinical trials related to Microcephaly.
Filter by:This is a retrospective single-center cohort study. The comparison in short- and long-term outcomes will be made between those with and without primary microcephaly in infants weighing ≤ 500 g.
This trial will consist of a clinical series of up to 50 children with Global Developmental Delay and concomitant microcephaly or hyperkinetic movements. All children will be assessed for psychomotor function using standardized assessments, goal specific assessments, with the potential addition of neuroimaging assessment, prior to and after receiving an intensive burst of neuromotor therapy. The interventional effects will be explored by comparing the pre and post interventional assessments and neuroimaging.
Microcephaly associated with Congenital Syndrome of the Zika virus (SCVZ) was highlighted due to atypical structural and behavioral changes of the central nervous system. Such changes contribute to the appearance of functional impairments and difficulties of adaptation of the child to the necessary therapeutic follow-up. In this context, the search for adjuvant therapies that allow better management of these alterations has grown and, given its advantages, aquatic physiotherapy may be an auxiliary resource in the care of this population. The aquatic environment is capable of promoting a state of relaxation that, when associated with a kinesiotherapy protocol, is believed to have this potentiated effect. Thus, our objective will be to evaluate the efficacy of aquatic physiotherapy on the level of stress and muscle tone in children with microcephaly associated with SCVZ. A crossover, randomized, controlled and blind study will be carried out with children between 3 and 24 months of age, who will undergo two interventions: aquatic physiotherapy and water immersion. The evaluation of muscle tone will be performed through the Tardieu scale before and after the intervention; the physiological parameters (heart and respiratory rate, oxygen saturation and temperature) and the stress level will be evaluated before, immediately after and 30 minutes after the intervention. In addition, questionnaires will assess the child's behavioral state, level of irritation and sleep characteristics. For data normalization the Shapiro Wilk Test will be applied; the percentage values and relative frequency will be used for the descriptive analysis and for the numerical variables the values of mean and standard deviation or median and interquartile range. The paired T and ANOVA tests for repeated samples will be applied, which will analyze the intra-group time factor for the dependent variables of each individual. And for intergroup analysis, the variables may be submitted to the T-Test for independent or Mann-Whitney samples.
The purpose of this study si to define morphological and epidemiological parameters and identify new symptoms in French patients with Seckel syndrome (SCKL) or microcephalic osteodysplastic primordial dwarfism type II (MOPDII).
This prospective cohort study will determine the natural history of fetal exposure to Zika virus (ZIKV) and its effects on the fetus and newborn with emphasis on neurodevelopment outcome. Exposure of the fetus will be determined by maternal symptomatology, RT-PCR ZIKV (blood and urine) and serologic test specific for ZIKV. Neonates will be classified according to trimester of infection and as exposed and unexposed to ZIKV.
It is suspected that zika virus infection during pregnancy is associated with microcephaly. The objective of this study is to investigate the occurrence of rash accompanied by three or more dengue-like signs and symptoms during pregnancy is related to the microcephaly using the case-control design.
In this study, measurements of fetal and maternal head circumference will be collected. This data will be presented in table or graph form. The effect of maternal head circumference on fetal head circumference will be evaluated and presented in either formula or graph form.
This project will make it possible to better understand the natural history of Cohen Syndrom and the phenotypes associated with mutations in the VPS13B gene, to improve the therapeutic management of patients. It will also provide a better description of Cohen-like syndrome for genetic counselling for the families concerned.
The purpose of this study is to: I. Compare neuroradiological phenotype and cognitive functioning of MCPH patients caused by ASPM mutations already characterized and published (Passemard et al. 2009a) with other MCPH-related patients (patients with MCPH1, WDR62, CDK5RAP2, CEP 152, CENPJ, STIL, or PCNT mutations) II. Describe the neuro-radiological and cognitive phenotype of microcephalic patients suffering from Fanconi anemia, and compared them to subjects with: - Fanconi anemia but normal OFC (head circumference) - MCPH patients - Healthy control subjects Our hypothesis is that mutations in genes responsible of microcephaly impact differentially cortical brain development and functioning
The purpose of this research is to study a new way to test for chromosome abnormalities. Chromosomes are strands of DNA (the genetic material in the cell nucleus) that are made up of genes-the units of heredity. Chromosome abnormalities are usually investigated by staining the chromosomes with a dye (Giemsa stain) and examining them under a microscope. This method can detect many duplications and deletions of pieces of chromosomes and is very accurate in diagnosing certain abnormalities. It is not useful, however, for identifying very small abnormalities. This study will evaluate the accuracy of a test method using 24 different dyes for finding small chromosome abnormalities. Children and adults with various chromosome abnormalities may be eligible for this study, including, for example, people with developmental delay or mental retardation, abnormal growth features or growth retardation, and certain behavioral disorders. Participants will be evaluated in the clinic over a 1- to 3-day period, depending on their symptoms. All participants will be examined by a genetics specialist and will have a physical examination and possibly X-rays, computerized tomography (CT) scans, magnetic resonance imaging (MRI), ultrasound studies and medical photography. Blood will be drawn for chromosome testing-about 3 tablespoons from adults and 1 to 3 teaspoons from children. When the test results are available, participants will return to the clinic for follow-up evaluation and review of the test findings. The genetic and medical evaluations, along with their implications, will be discussed.
