purpose: to report visual outcomes of pars plana vitrectomy in severely traumatized eyes with no light perception (nlp) and flat electroretinography (erg) methods: we performed a prospective interventional study on 22 severely traumatized eyes with nlp, 4+ relative afferent pupillary defect (rapd) and flat erg. results: one year after pars plana virectomy, 15 patients (68.18%) had nlp, six pati...

INTRODUCTION: The cortico-cavernous fistula is uncommon and uncommonly uncommon. A characterized by an abnormal vascular connection between the internal or external carotid arteries venous channels of cavernous sinus. If left untreated, it might cause additional complications such as intracerebral hematoma, subarachnoid hemorrhage, epistaxis, otorrhagia. Secondary glaucoma.CASE PRESENTATION: in...

The threat simulation theory of dreaming (TST) () states that dream consciousness is essentially an ancient biological defence mechanism, evolutionarily selected for its capacity to repeatedly simulate threatening events. Threat simulation during dreaming rehearses the cognitive mechanisms required for efficient threat perception and threat avoidance, leading to increased probability of reprodu...

OBJECTIVE Personality is defined as the trait-like qualities of a person. However, it has been recently suggested that the state effect of a situation leads to changes in scores on personality assessments. We predicted that traumatic experiences would induce changes not only in personality scores but also in the factor structures of personality assessments. METHODS MethodsaaWe conducted a cro...

Results: The anxiety indices of the traumatized rats were markedly higher than those of the controls (p<0.05). GluN1 and calmodulin levels were decreased in the dorsal hippocampus and amygdaloid complex of the traumatized rats. NOS expression increased significantly in both the amygdaloid complex and dorsal hippocampus where the increase was statistically more prominent in the amygdaloid comple...

OBJECTIVE To examine the psychometric properties and utility of a Child Behavior Checklist-Posttraumatic Stress Disorder (CBCL-PTSD) Scale to screen for posttraumatic stress disorder (PTSD) in traumatized preschool children. METHOD Data for this study were drawn from a study of young child trauma and consisted of 62 traumatized children, 23 months through 6 years of age. The children's mother...

MR imaging after IV gadolinium-DTPA administration has demonstrated contrast enhancement in traumatized lumbar intervertebral disks. To characterize the morbid anatomy that correlates with the contrast enhancement, we developed a canine model of traumatized intervertebral disks. Diskectomy was performed with a nucleotome and the spines were imaged biweekly with MR and Gd-DTPA. The spines were s...

Injury to the superficial layers of cerebral cortex produces alterations in the synaptic responses of local circuits that promote the development of seizures. To further delineate the specific changes in synaptic strength that are induced by this type of cortical injury, whole cell voltage-clamp recordings were used to examine evoked and spontaneous synaptic events from layer V pyramidal cells ...

Mammalian hair cells possess only a limited ability to repair damage after trauma. In contrast, sea anemones show a marked capability to repair damaged hair bundles by means of secreted repair proteins (RPs). Previously, it was found that recovery of traumatized hair cells in blind cavefish was enhanced by anemone-derived RPs; therefore, the ability of anemone RPs to assist recovery of damaged ...
