Active clinical trials for "Craniosynostoses"

Being the craniostenoses sutural basically a disease, the fact that the brain being trapped in an enclosure that does not have complacency required to accompany their growth constitutes the challenge of treatment, which aims to restore the complacency of the suture and correct the stenotic compensatory cranial deformity. This paper proposes the combination of a helicoid osteotomy distraction osteogenesis provided by the use of springs distracting.

This study will explore the range and type of medical and developmental problems in patients with Muenke syndrome, a condition that results when one or more of the suture between the bones of the skull close before birth. Because of the premature closure, the skull is not able to grow in its natural shape; instead, it compensates with growth in areas of the skull where the sutures have not yet closed. This can result in an abnormally shaped head, wide-set eyes, and flattened cheekbones. Patients may also have an enlarged head, abnormalities of the hands or feet, and hearing loss. The fibroblast growth factor receptor 3 (FGFR3) gene, which is involved in the development and maintenance of bone tissue, plays a role in Muenke syndrome. In some cases, the FGFR3 mutation is inherited from a parent with Muenke syndrome; in other cases, where there is no family history of the disorder, the mutation occurs anew. A better understanding of this gene may lead researchers to develop better treatments and genetic counseling for people affected by Muenke syndrome. Patients with Muenke syndrome and their blood relatives may be eligible for this study. Family members with confirmed Muenke syndrome will have genetic counseling, and patients undergo the following tests and procedures: Review of medical records and test results. Questionnaires about the patient's prenatal, birth, newborn, and past medical history; family history; growth and development; medications; and current therapies. Physical, neurological, ear, nose and throat, dental, and eye examinations. Neuropsychological testing to assess cognitive thinking abilities. Hearing evaluation. This includes an audiology test in which the patients listens to soft tones through earphones; a power reflectance test in which a chirping sound is heard through an earpiece placed at the entrance to the ear canal, and possibly an ABR/ASSR test, in which electrodes are attached to the forehead, earlobes, and behind the ears to measure brain waves in response to certain conditions. MRI scan of the brain. MRI uses a strong magnetic field and radio waves to produce detailed pictures of the brain. During the scan, the patient lies on a table in a narrow cylinder (the scanner), wearing ear plugs to muffle loud noises that occur with electrical switching of the magnetic fields. MRI scan of the middle and inner ear. This test is similar to the MRI, but uses a dye injected in a vein to enhance the images. CT scan of the skull. CT uses x-rays to produce 3-dimensional images of the part of the body studied. Dental evaluation with x-rays. Skeletal survey (x-rays of all bones of the body). Developmental assessment of IQ testing. Blood tests for research purposes. A cell line may be established for use in future research. Medical photographs to demonstrate clinical features, including side and front views of the face, head, and other parts of the body that may be involved in Muenke syndrome, like the hands and feet. Other consultations or tests as clinically indicated

This study will try to find the gene changes responsible for the birth defects in craniosynostosis, Philadelphia type. Craniosynostosis syndromes are a group of conditions that result from closure of one or more of the fibrous joints between the bones of the skull before brain growth is complete. Because of the premature closure, the brain is not able to grow in its natural shape; instead, it compensates with growth in areas of the skull where the joints have not yet closed. The defects in raniosynostosis, Philadelphia type, include skull malformations and webbing of the fingers and toes. Gene changes known to be involved in other craniosynostosis syndromes have not been found in the Philadelphia type syndrome. Therefore, finding the genetic basis of this disorder will provide important new information regarding craniofacial and limb development. This study includes members of a single large family affected with craniosynostosis, Philadelphia type. Participants have 1 to 2 teaspoons of blood drawn for genetic studies. A second blood sample may be requested for further research. Some blood may be used to establish a cell line for later studies. This involves growing the white blood cells from the blood sample. The cells can be kept in the laboratory to make more DNA or can be frozen for later use in craniosynostosis studies. Patients may also have their medical records reviewed.

To learn more about the cognitive and motor development of infants and young children born with a craniofacial defect called craniosynostosis.

The purposes of this study are: to better understand the experience of the announcement for the diagnostic of craniosynostosis to patients and their families to improve the understanding of it and it modes of appropriation to compare the announcement process concerning "simple" and "complex" forms. to identify the intra-family issues at the announcement of a genetic mutation. to reconstruct the care course of patients by analyzing the time of the announcement and the post-operative period.

Craniosynostosis is a condition where infants are born with or subsequently develop an abnormally shaped skull. The skull develops from plates of bone separated from each other by growth lines (sutures). Craniosynostosis refers to early fusion of one or more of these sutures. Whilst in many cases the abnormal head shape provides doctors with the underlying diagnosis, it is necessary to confirm this using imaging. A CT scan involves using multiple x-rays to build a picture of the part of the body being examined. X-rays are associated with potential long term harm, particularly in young children who have longer to incur those risks. MRI uses magnets and radiowaves to create images of the body, and therefore a radiation-free method of imaging. The investigators have previously shown in a pilot group that a specific MRI technique ("Black Bone") can distinguish between normal and prematurely fused cranial sutures, and that the images can be reconstructed in 3D in the same way as CT. The investigators now need to confirm the findings in a larger patient group, and develop automated methods of creating 3D images of the bone. Children in whom there is clinical suspicion of craniosynostosis will be recruited for MRI examination. In children who are already undergoing MRI examination of the head (for any indication), the investigators will add on bone specific sequences. There are no known long term risks associated with MRI, and no contrast medium is required. Anonymised MRI data will be used to further develop our 3D techniques.

Craniosynostosis is a malformation affecting the head and face, in which one or more sutures in the skull are fused prematurely. Premature union of one or more sutures causes changes in the shape of the skull base and dome, resulting in asymmetrical or restricted head and facial enlargement. It has been reported that in craniosynostosis, the bone enlargement is perpendicular to the fused sutures with the counterbalancing expansion. Craniosynostosis usually involves the union of a single cranial suture, but in some cases it has been observed that it may involve more than one suture in the baby's skull. An asymmetrical appearance is observed on the faces of babies, especially an unusual appearance in the form of eyes and skulls. It may present with neurological defects such as hydrocephalus, mental retardation, vision and hearing loss, as well as cosmetic deformities in the skull and facial bones. The general prevalence of craniosynostosis is around 1/2500 births. Generally, in single suture synostoses, there is no clear neurological finding except deformity. In multisuture synostoses there are a wide spectrum of findings such as increased intracranial pressure, hydrocephalus, syringomyelia, Chiari malformation, venous anomalies, ophthalmologic problems, growth retardation and epilepsy. Early diagnosis and treatment provides enough room for the baby's brain to grow and develop. It is thought that by measuring the anthropometric properties of these babies, the course of their development will be examined.

This is a prospective study to evaluate outcomes in patients undergoing endoscopic craniectomy for isolated, single-suture craniosynostosis.

Postoperative pain is a major concern in routine management of children admitted to pediatric intensive care treatment. There are significant negative physiological and psychological ramifications of postoperative pain such as impairment of cardiac function due to tachycardia, restlessness in an intubated patient requiring increase dosage of sedative and paralytic drugs and reduced patient cooperation in the healing process. The main body of evidence dealing with gender differences in pain perception and treatment stems from studies in the adult and adolescent population as the gonadal hormones have a central role in the way one experiences pain The hypothesis of this study is that there is a difference in the perception of pain, the amount of analgesia used and the response to pain medication between male and female infants undergoing craniosynostosis repair or untethering of cord.
