BACKGROUND Bifrontal contusion is a common clinical brain injury. In the early stage, it is often mild, but it progresses rapidly and frequently worsens suddenly. This condition can become life threatening and therefore requires surgery. Conventional decompression craniectomy is the commonly used treatment method. In this study, the effect of intracranial pressure (ICP) monitored stepwise intra...

BACKGROUND AND PURPOSE Osteogenic protein-1 (OP1) not only possesses trophic activity on bone tissue but also influences neuronal survival and differentiation in vitro. Specific receptors for OP1 are present in brain and spinal cord and can be upregulated during cerebral contusion. OP1 is a member of the transforming growth factor-beta superfamily, several of whose members possess neuroprotecti...

Pulmonary contusion is a common injury following motor vehicle crash (MVC). The estimated mortality rates for this injury range from 10% to 20%. Another important clinical implication of this lesion is the potential for development of Acute Respiratory Distress Syndrome (ARDS). Studies have correlated an increased risk of ARDS with a pulmonary contusion extent exceeding 20% of the total lung vo...

This study tried to quantify spinal cord perfusion by using contrast-enhanced ultrasound (CEUS) in rhesus monkey models with acute spinal cord injury. Acute spinal cord perfusion after injury was detected by CEUS, coupling with conventional ultrasound (US) and Color Doppler US (CDFI). Time-intensity curves and perfusion parameters were obtained by autotracking contrast quantification (ACQ) soft...

Cardiac contusion is an infrequent but occasionally serious complication of deceleration injury. According to ATLS teaching, the true diagnosis of contusion can only be established by direct inspection of the myocardium. The clinically important sequelae of myocardial contusion are hypotension and arrhythmia. Despite recent advances in investigative techniques, myocardial trauma remains an impo...

BACKGROUND Acute subdural hematoma is usually associated with cerebral contusion or laceration of the bridging veins following a head injury. However, several cases of acute subdural hematoma without head injury (acute spontaneous subdural hematoma) have been reported. METHODS Among 162 cases of acute subdural hematoma admitted to our departments between 1996 and 2003, we repoort eight cases ...

OBJECTIVE In view of the association of the apolipoprotein E (APOE) epsilon 4 allele with poor outcome after traumatic brain injury we determined the frequency of cerebral amyloid angiopathy (CAA) and the extent of haemorrhagic pathology in relation to APOE genotype in an autopsy series of 88 head injured cases. METHODS Tissue sections from the frontal and temporal lobes were immunostained fo...

Spinal cord injury (SCI) causes chronic pain in 65% of individuals. Unfortunately, current pain management is inadequate for many SCI patients. Rodent models could help identify how SCI pain develops, explore new treatment strategies, and reveal whether acute post-SCI morphine worsens chronic pain. However, few studies explore or compare SCI-elicited neuropathic pain in rats. Here, we sought to...
