traumatic brain injury (tbi) is described by a disruption in the normal function of the brain due to an injury following a trauma, which can potentially cause severe physical, cognitive, and emotional impairment. the use of human stem cells and self-assembling peptide scaffolds suggest huge potential for application in the treatment of tbi. in the present study, we surveyed the beneficial effec...

background cerebral state index (csi) is derived from electroencephalograms to monitor the level of consciousness during anesthesia. some evidence shows that this indicator has been used to detect cerebral ischemia and prognostic outcomes for traumatic brain injury (tbi). objectives the present study was designed to investigate the correlation between glasgow coma score (gcs) and csi for brain-...

traumatic basal ganglia hematoma is a rare condition defined as presence of hemorrhagic lesions in basal ganglia or adjacent structures suchas internal capsule, putamen and thalamus. bilateral basal ganglia hematoma are among the devastating and rare condition. we herein report a 28-year old man, a victim of car-car accident who was brought to our surgical emergency room by immediate loss of co...

avulsion is a serious injury which causes damage to dental and supportive tissues, ranging from 1-16 % among dental injuries and it mostly occurs in maxillary incisors. this report presents a case of replantation of a traumatically avulsed central incisor. the left central incisor of an 8 year-old boy with open apex was avulsed and was left in unclean and dry conditions. tooth was replaced afte...

We explored whether parents of our pediatric patients valued the diagnostic terms "concussion," "minor traumatic brain injury," and "mild traumatic brain injury" as equivalent or nonequivalent. 1734 of 2304 parents attending a regional pediatric emergency department completed a brief questionnaire assessing the equivalence or nonequivalence of the diagnostic terms "concussion," "minor traumatic...

We report here the case of a 35-year-old man who presented with inferior vena cava thrombosis (IVCT) after blunt hepatic trauma. The IVCT was incidentally detected by computed tomography (CT) 35 days after deep parenchymal suturing and suture approximation for liver lacerations. The patient denied any symptoms of thrombophlebitis. However, he had presented with significantly elevated values of ...

Severe traumatic brain injury is associated with both acute and delayed neuro- logical injury. Cerebral vasospasm is commonly associated with delayed neurological decline in aneurysmal subarachnoid hemorrhage patients. However, the role played by vasospasm in traumatic brain injury is less clear. Vasospasm occurs earlier, for a shorter duration, and often without significant neurological conseq...

Traumatic brain injury affects systemic circulation as well as directly damages the brain. The present study examined the effects of fluid percussion brain injury on systemic hemodynamics and organ arterial blood flow in rats. Rats were prepared for fluid percussion injury under anesthesia. Twenty-four hours later, rats were anesthetized (1.0% halothane in N2O:O2) and prepared for radioactive m...

introduction drug-induced liver injury is a frequent cause of hepatic dysfunction. several drugs have been identified to cause autoimmune hepatitis (aih). environmental chemicals are capable of triggering a certain degree of liver injury. however, toxin induced aih is rare. conclusions chronic (long-term) exposures to dichlorvos can lead to aih. a detailed inquiry of medical history and liver b...
