BACKGROUND The goal of this study is to determine the presence of platelet dysfunction in patients with traumatic brain injury (TBI). The mechanisms underlying the coagulopathy associated with TBI remain elusive. The question of platelet dysfunction in TBI is unclear. METHODS This was a prospective observational study conducted at Memorial Hospital of… (More)
Four cases of cerebrospinal fluid (CSF) ascites secondary to ventriculoperitoneal shunting are described. It is possible to differentiate CSF ascites from a CSF-filled pseudocyst by the characteristic bowel gas pattern on films of the abdomen and by the presence of shifting dullness. Two of the patients had active shunt infections, and had ascitic fluid… (More)
A 55-year-old man presented with dementia and seizures of recent onset. A computerized tomography scan revealed a ring-like lesion in the left occipital lobe, which on resection was found to be a histoplasmoma. Cerebral histoplasmoma is rare and simulates a metastatic brain tumor. Only eight cases of this entity have been reported.
Acute coagulopathy is a serious complication of traumatic brain injury (TBI) and is of uncertain etiology because of the complex nature of TBI. However, recent work has shown a correlation between mortality and abnormal hemostasis resulting from early platelet dysfunction. The aim of the current study was to develop and characterize a rodent model of TBI… (More)
BACKGROUND Coagulopathy in traumatic brain injury (CTBI) is a well-established phenomenon, but its mechanism is poorly understood. Various studies implicate protein C activation related to the global insult of hemorrhagic shock or brain tissue factor release with resultant platelet dysfunction and depletion of coagulation factors. We hypothesized that the… (More)
Fentanyl is an attractive agent for analgesia in the emergency department. Its use in this setting has been limited to IV bolus administration. We report successful sedation, muscle relaxation, and analgesia of a multiple trauma patient with fentanyl IV bolus and continuous infusion in the ED.
Incubation of liver slices and isolated liver cells with adenosine cyclic-3′,5′-monophosphate at concentrations which inhibit lipogenesis was found to expand the pool size of the noncyclic adenine nucleotides in the intact cells of the preparations. This observation led to studies which demonstrated that adenosine and adenosine-5′-monophosphate also… (More)
Denervated frog sartorius muscles showed an approximately 2--3 fold increase of cyclic GMP in their end-plate rich regions which did not appear up to 5 weeks after denervation in the normally end-plate-free pelvic region. No increase in cyclic AMP was seen in these preparations. The results suggest that the increase of cyclic GMP is related to processes… (More)
