traumatic brain injury (tbi) is an important cause of death and disability in young adults ,and may lead to physical disabilities and long-term cognitive, behavioral psychological and social defects. there is a lack of definite result about the effect of thyroid hormones after traumatic brain injury in the severity and no data about their effect on mortality of the injury. the aim of this study...

Head injury is one of the most important types of injury and is responsible for most of the deaths due to trauma. Low-income and middle-income countries face with more risk factors, but they still lack adequate health-care capacity to deal with complications. Trauma literally means the damage and injury, and head injury was defined as physical damage to the brain or skull caused by external for...

Background: Injury is a leading cause of morbidity and mortality in children. There is insufficient data on the epidemiology or incidence of injuries in the first two years of life, especially in Iran. The main objective of this study was to describe the incidence and causes of injuries in a sample group of infants and toddlers in Mashhad, Iran. Methods: This prospective, observational study, ...

Organ damage after reperfusion of previously viable ischemic tissues is defined as ischemia/reperfusion injury. The pathophysiology of ischemia/reperfusion injury involves cellular effect of ischemia, reactive oxygen species and inflammatory cascade. Protection against ischemia/reperfusion injury may be achieved by preconditioning or postconditioning. In this review, we discuss basic mechan...

Introduction: Spinal cord injury (SCI) is one of the most serious clinical diseases, which not only affects the patient's physical and mental status, but its effects will be spread to family and community. After severe spinal cord injury, astrocytes of the central nervous system (CNS) become reactive astrocytes, and play the main role of glial scar formation. The scar is a major obstacle to r...

Background: Occult dural injuries are rare and can occur as a result of major or minor head injury. These injuries usually manifest with cerebrospinal fluid rhinorrhea alone, or with meningitis and cerebral abscess, sometimes many years after the original injury. Case presentation: We present a case of occult dural injury with endocranial complications which occurred in a 34 year old man, wi...

Introduction: Following a traumatic brain injury (TBI), the excessive release of proinflammatory cytokines is major cause of cerebral edema that can cause permanent neuronal loss. This study examined the changes in brain concentrations of proinflammatory cytokines IL-1, IL-6, TNF-α and TGF- after different doses of estrogen or progesterone treatment in brain-injured rats at 6 and 24 h post...

Background: Following spinal cord injury, reactive astrocytes upregulate chondroitin sulfate proteoglycans (CSPGs) which act as a barrier to neuronal repair and regeneration. Therefore, enzymatic digestion of CSPGs by chondroitinase ABC (cABC) is a key strategy in the treatment of spinal cord injury. Furthermore, cABC has been shown to attenuate post spinal cord injury inflamma...
