Eighty-five patients with refractory transformed migraine type of chronic daily headache (CDH) had spinal tap as a part of diagnostic work-up. Twelve had increased intracranial pressure without papilledema, transient visual obscurations, or visual field defects. The headache profile of these 12 patients was not different from that of transformed migraine type of CDH. Acute headache exacerbation...

BACKGROUND Hyperthermia is a common secondary insult in traumatic brain injury (TBI). The aim was to evaluate the relationship between hyperthermia and intracranial pressure (ICP), and if intracranial compliance and cerebral blood flow (CBF) pressure autoregulation affected that relationship. The relationships between hyperthermia and cerebral oximetry (BtipO2) and cerebral metabolism were also...

The aim of the present study was to ascertain whether aminoguanidine attenuated intracranial hypertension and cerebral ischemic injury in experimental heatstroke. Urethane-anesthetized rats were exposed to heat stress (ambient temperature of 43 degrees C) to induce heatstroke. Control rats were exposed to 24 degrees C. Mean arterial pressure, cerebral perfusion pressure, and cerebral blood flow...

Although the majority of alterations in sensorium in cancer patients are caused by endogenous or exogenous intoxication, the clinician must be alert to the possibility of structural disease in any patient who experiences a change in mental status. Accurate diagnosis of structural disease and prompt intervention can significantly improve the outcome of cancer treatments. Mogami et al. (1983) not...

INTRODUCTION Idiopathic intracranial hypertension is a rare condition characterized by increased intracranial pressure without clinical, laboratory, or radiological evidence of intracranial pathology. Early management could prevent irreversible outcomes. CASE PRESENTATION A 17-year-old single Arabian female of Arab origin presented with a 2-day complaint of horizontal diplopia and transient v...

The diameters of pial vessels in the cat were measured through a closed cranial window after i.v. injection of dihydralazine (250 microgram or 1 mg x kg-1). The intracranial pressure was recorded from a needle in the cisterna magna. In 7 cats given 1 mg x kg-1 dihydralazine, arterial vessels with a resting diameter of 72 +/- 24 micron (SD) dilated by 58 +/- 21% (p < 0.01), with no significant c...
