objective(s):estrogen (e2) has neuroprotective effects on blood-brain-barrier (bbb) after traumatic brain injury (tbi). in order to investigate the roles of estrogen receptors (ers) in these effects, er-α antagonist (mpp) and, er-β antagonist (phtpp), or non-selective estrogen receptors antagonist (ici 182780) were administered. materials and methods: ovariectomized rats were divided into 10 gr...

There is scant neuropathological information in the child abuse literature; even the best reviews include assumptions based on the findings of a few inadequate early studies. Our recent series of 53 fatal cases (Brain 124 (2001) 1290, 1299 [1,2]) demonstrated age-related patterns of brain injury and showed the substrate of severe encephalopathy in the infants to be hypoxic brain damage, not dif...

Modified mesenchymal stromal cells (MSCs) display a unique mechanism of action during the repair phase of traumatic brain injury by exhibiting the ability to build a biobridge between the neurogenic niche and the site of injury. Immunohistochemistry and laser capture assay have visualized this biobridge in the area between the neurogenic subventricular zone and the injured cortex. This biobridg...

introduction guillain-barre syndrome (gbs) is an immune-mediated acute inflammatory disorder of the peripheral nervous system. infectious agents were usually accused of playing a role in the etiology of gbs. guillain-barre syndrome has rarely been reported following subdural and subarachnoid hemorrhage after head trauma. case presentation we report on a 63-year-old male patient presenting gbs f...

traumatic brain injury is a leading cause of death in developed countries. it is estimated that only in the united states about 100,000 people die annually in parallel among the survivors there is a significant number of people with disabilities with significant costs for the health system. it has been determined that after moderate and severe traumatic injury, brain parenchyma is affected by m...

traumatic brain injury is a common entity. however cerebral infarction in infants is a rare entity while the diagnosis of this pathology in the pediatric population is usually difficult. the mild head trauma is rarely accompanied by intracranial injury and even less, with cerebral infarction. we herein report the first case of cerebral infarction after a mild brain trauma in a 2-year-old latin-...

the sex hormone progesterone has been shown to improve outcomes in animal models and two early-phase trials involving patients with traumatic brain injury (tbi). the aim of this clinical study was to assess the effect of progesterone on the improvement of neurologic outcome in patients with diffuse and acute tbi. a prospective, randomized, double-blind trial of progesterone was conducted in our...

traumatic brain injury (tbi) results from a sudden and external physical impact to the head, and often leads to motor and cognitive impairment. using tissue engineering strategies, we aimed to review aspects of extra cellular matrix (ecm) based scaffold that could be delivered to the injured brain. the ecm is produced intracellularly and secreted to form a dense network of proteins and glycans,...

catatonia is a syndrome that can be treated with electroconvulsive therapy (ect). hence, onset of catatonia during treatment of patients with ect is not expected. in this manuscript, a schizoaffective disorder patient with a positive history of traumatic brain injury and no consumption of benzodiazepines is being reported, who became catatonic during ect.

the prevalence of spinal cord injury (sci) is about 2.5 million in the worldwide and more than 130,000 new injuries reported each year. regeneration in the cns versus the pns is very different from the other tissues and many factors can prevent regeneration in pns and specially cns. previous researches demonstrated that regeneration of cns can inhibit by inhibitory molecules and glial scar. the...
