Influence of General Anesthesia on the Dynamic Changes in Brain Damage Markers During and After...
CraniosynostosisAnesthesiaThe issue of anesthetics neurotoxicity is one of the most discussed topics in pediatric anesthesiology, thus it opens the question of the safety of commonly used anesthetics in the pediatric patient. Preclinical studies have shown that anesthetics can have a toxic effect on the maturing brain of pups and cause cognitive impairment. In human medicine, the influence of anesthetics is studied by monitoring the psychomotor development of children who have undergone surgery under general anesthesia. Some work deals with laboratory evidence of brain damage due to general anesthesia, but none of the work deals with the observation of markers of brain damage in infants. The aim of this work is to examine the dynamics of changes in the concentrations of selected markers of brain damage in craniosynostosis operations under general anesthesia in infants in order to optimize perioperative management and the correct timing of surgery.
CraNIRS Clinical Study
CraniosynostosesCraniosynostosis is a rare disorder characterized by a premature fusion of one or more sutures of the skull. Craniosynostosis is usually diagnosed in the first years of life. Several complications may be identified if untreated, notably, developmental delay, and vision problems. In some patients with craniosynostosis a decrease in cerebral blood perfusion can be identified. It might be related to the constriction of the brain caused by premature sutural fusion or the localized constriction of venous sinuses. In this study the investigator use the NIRS which is defined as a non-invasive technique to monitor hemodynamic parameters and hemoglobin oxygen saturation of the brain during the surgical correction of the craniosynostosis. By applying this method the investigator will be able to analyse the changes in cerebral hemoglobin oxygen saturation related to the modification of the skull. Determining changes in brain oxygen saturation by using NIRS before, during and after surgery will help both to better understanding the impact of surgical decompression on improving cerebral oxygenation and to better adapt anaesthesia strategies during surgery.
Blood Loss and Transfusion Requirement in Infants Treated With Tranexamic Acid
CraniosynostosesThe primary objective of this study is to investigate whether tranexamic acid (TXA) reduces perioperative blood loss and transfusion requirement in infants undergoing craniosynostosis surgery.
GROWing Up With Rare GENEtic Syndromes
Prader-Willi SyndromePWS-like Syndrome32 moreIntroduction Rare complex syndromes Patients with complex genetic syndromes, by definition, have combined medical problems affecting multiple organ systems, and intellectual disability is often part of the syndrome. During childhood, patients with rare genetic syndromes receive multidisciplinary and specialized medical care; they usually receive medical care from 3-4 medical specialists. Increased life expectancy Although many genetic syndromes used to cause premature death, improvement of medical care has improved life expectancy. More and more patients are now reaching adult age, and the complexity of the syndrome persists into adulthood. However, until recently, multidisciplinary care was not available for adults with rare genetic syndromes. Ideally, active and well-coordinated health management is provided to prevent, detect, and treat comorbidities that are part of the syndrome. However, after transition from pediatric to adult medical care, patients and their parents often report fragmented poor quality care instead of adequate and integrated health management. Therefore, pediatricians express the urgent need for adequate, multidisciplinary adult follow up of their pediatric patients with rare genetic syndromes. Medical guidelines for adults not exist and the literature on health problems in these adults is scarce. Although there is a clear explanation for the absence of adult guidelines (i.e. the fact that in the past patients with rare genetic syndromes often died before reaching adult age), there is an urgent need for an overview of medical issues at adult age, for 'best practice' and, if possible, for medical guidelines. The aim of this study is to get an overview of medical needs of adults with rare genetic syndromes, including: comorbidities medical and their impact on quality of life medication use the need for adaption of medication dose according to each syndrome Methods and Results This is a retrospective file study. Analysis will be performed using SPSS version 23 and R version 3.6.0.
Tranexamic Acid for Craniofacial Surgery
CraniosynostosisBleedingThis is a randomized, blinded, prospective study that will investigate the potential benefit of tranexamic acid to reduce the intraoperative bleeding and blood transfusions in pediatric patients undergoing craniofacial surgeries.
Cranial Cup Use for the Prevention of Positional Head Shape Deformity in the NICU
PlagiocephalyScaphocephaly1 moreMany hospitalized infants can develop a flattening of the back or sides of their head. This condition develops gradually when an infant's head rests on a firm or semi-firm surface for a prolonged period of time. Premature infants are more likely to have a positional head shape deformity because they may spend longer periods of time in a crib. Infants participating in this study will be randomly assigned to either standard treatment, which is a moldable positioner device, or to a cranial cup device and moldable positioner for positioning. The purpose of this prospective single-blinded randomized clinical trial will be to evaluate the effectiveness of the cranial cup in preventing positional head shape deformity in the NICU patient population.
The Efficacy and Population Pharmacokinetics of Tranexamic Acid for Craniosynostosis Surgery
CraniosynostosisThis research study is being performed to evaluate two different doses of Tranexamic acid (TXA) in children who have craniosynostosis and have been referred to Boston Children's Hospital for corrective surgery. This surgery is associated with significant blood loss and frequently requires the transfusion of blood. TXA is a medication that reduces the amount of bleeding during surgery by improving clotting of the blood at the surgical site. TXA is an FDA-approved drug that is routinely used in infants and children undergoing major surgery including heart surgery, craniofacial surgery and scoliosis surgery. It has been shown to decrease both the amount of bleeding and the amount of blood transfusion needed. We would like to compare the different doses of TXA to see if a lower dose has the same effect on blood loss as a higher dose. We are also interested to learn why TXA seems to work better in some patients than in others. In order to study the effect of this drug we would like to give this drug to your child and measure the blood loss and the volume of blood given to your child during his/her surgery. The research is being done at two sites; Boston Children's Hospital and Gaslini Children's Hospital in Genoa, Italy. The main study doctor from Boston Children's Hospital is Dr. Susan Goobie. The Department of Anesthesiology at Boston Children's Hospital is sponsoring this study. We are planning to study a total of 68 infants and children from age 3 months to 6 years old scheduled for open craniosynostosis surgery at Boston Children's Hospital or Gaslini Children's Hospital.
Amicar Pharmacokinetics of Children Having Craniofacial Surgery
CraniosynostosisCraniofacial reconstruction surgery involves a surgical approach to the craniofacial region to repair cranial vault and facial deformities. The surgery is extensive, often requiring wide scalp dissections and multiple osteotomies and has been associated with significant morbidity. Some of the most severe and commonly seen problems are associated with the rate and extent of blood loss. Efforts to minimize surgical bleeding may translate to reduced transfusion requirements and a lessening of associated risks Epsilon-aminocaproic acid (EACA), an inhibitor of fibrinolysis, reduces transfusion requirements in children undergoing procedures on cardiopulmonary bypass (CPB), as well as in older children undergoing spinal surgery for scoliosis (1-6). Before controlled studies to assess efficacy of EACA in a craniofacial surgical population can be done, appropriate pharmacokinetic (PK) data are needed to determine the optimal dosing strategy. PK data exist for EACA in children undergoing operations on CPB and hypothermia. The aim of this study is to determine the pharmacokinetics of EACA in infants and children undergoing craniofacial reconstruction procedures.
Network Of Clinical Research Studies On Craniosynostosis, Skull Malformations With Premature Fusion...
CraniosynostosisCraniosynostosis (CS) is a common malformation occurring in ~4 per 10,000 live births in which the sutures between skull bones close too early, causing long-term problems with brain and skull growth. Infants with CS typically require extensive surgical treatment and may experience many perioperative complications, including hemorrhage and re-synostosis. Even with successful surgery, children can experience developmental and learning disabilities or vision problems. Most often, CS appears as isolated nonsyndromic CS (NSC). Of the several subtypes of CS, unilateral or bilateral fusion of the coronal suture is the second most common form of CS accounting for 20-30% of all NSC cases. The etiology of coronal NSC (cNSC) is not well understood, although the published literature suggests that it is a multifactorial condition. About 5-14% of coronal craniosynostosis patients have a positive family history, with a specific genetic etiology identified in >25% of cNSC cases, suggesting a strong genetic component in the pathogenesis of this birth defect. The causes for cNSC and its phenotypic heterogeneity remain largely unknown. An international team of investigators will generate large genomic and gene expression datasets on samples from patients with cNSC. State-of-the-art imaging, genetic, and developmental and systems biology approaches will be used to quantitatively model novel pathways and networks involved in the development of cNSC. Novel variant-, gene- and network-level analyses will be performed on the genomic data obtained from cNSC cases, their relatives, and controls to identify novel variants and genetic regions associated with cNCS. Quantitative, analytical, and functional validations of these predictions will provide insights into the etiology and possible therapeutic targets for CS and potentially other bone-related disorders.
Hanger Helmet Study
PlagiocephalyCraniosynostosisThe purpose of this study is to examine a group of patients requiring helmet therapy (either patients with plagiocephaly or post-surgical patients) to compare outcomes of infants treated with the Hanger helmet (Hanger, Inc.) to outcomes of infants treated with the P Pod Helmet (Lorica Scientific, LLC). Currently both helmets are prescribed at CCHMC. The investigators' goal is to determine which helmet is more effective in skull remodeling and to standardize the investigators' care for these patient types.
