Filter by:The primary objective of this study is to investigate whether tranexamic acid (TXA) reduces perioperative blood loss and transfusion requirement in infants undergoing craniosynostosis surgery.
In this study we want to compare the effectiveness of a bone substitute (Allogenix Plus, a product derived from a dead human being that has chosen to donate it prior to dying) and bone dust from the patient's own bone pieces, versus bone dust alone in filling in the gaps that sometimes occur after surgery for craniosynostosis . We will compare the percent of defect filled at 1 year in 5 patients 18 months or older with metopic craniosynostosis that received the bone substitute plus their bone dust with 5 previously operated patients with similar characteristics that received bone dust alone to fill in the gaps. The bone substitute that we are using will be provided at no cost by the company Biomet Microfixation. The bone substitute Allogenix Plus undergoes extensive screening for infectious diseases as well as processing to prevent a rejection. The product will be applied during standard surgery to 5 patients with metopic craniosynostosis of 18 months or older with skull defects no larger than 25 cm2, so it does not require any additional surgeries. Aside from the placement of this bone substitute the patient will proceed to receive the standard of care which includes a pre-operative CT scan, immediate post-operative CT scan, and 1 year post-operative CT scan of the Head. We will review these scans and look at percent of bony growth in the bone substitute plus bone dust group . We will also see the patients in clinic, during standard of care follow-up visits at 1 week, 3 weeks, 6 weeks, 12 weeks, 6 months, and 1 year post-operatively. During clinic visits we will monitor the patient closely for any potential side effects of the bone substitute as well as complications of the surgery. We will then review the charts of 5 patients 18 months or older that have undergone surgery for metopic craniosynostosis until 5 patients with similar characteristics and defect size have been obtained. We will compare their post-operative CT scans and pictures and we will look at bone growth, bone resorption, bone gaps present, and need for secondary surgeries.
Craniofacial 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.
The primary objectives of this study are - to procure human temporalis muscle, subcutaneous adipose (fat), and bone tissue samples from children with craniosynostosis, - to grow cells from these tissues in vitro, - to evaluate the osteogenic potentials of these cell types.
This is a prospective study to evaluate outcomes in patients undergoing endoscopic craniectomy for isolated, single-suture craniosynostosis.
This 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.
The research purpose is to determine if thymus transplantation with immunosuppression is a safe and effective treatment for complete DiGeorge anomaly. The research includes studies to evaluate whether thymus transplantation results in complete DiGeorge anomaly subjects developing a normal immune system.
The study purpose is to determine if cultured thymus tissue implantation (CTTI) (previously described as transplantation) with tailored immunosuppression based on the recipient's pre-implantation T cell population is a safe and effective treatment for complete DiGeorge anomaly. This study will also evaluate whether cultured thymus tissue implantation and parathyroid transplantation with immunosuppression is a safe and effective treatment for complete DiGeorge anomaly and hypoparathyroidism.
One purpose of this study is to determine whether the amount of cultured thymus tissue implanted into DiGeorge anomaly infants has any effect on the immune outcome. Another purpose of this study is to determine whether parental parathyroid transplantation (in addition to cultured thymus tissue implantation (CTTI) can help both the immune and the calcium problems in DiGeorge infants with hypocalcemia.

The study purpose is to determine whether cultured thymus tissue implantation (CTTI) is effective in treating typical complete DiGeorge syndrome.
