BACKGROUND Spontaneous intracranial hypotension (SIH) results from leaks developing in the dura mater. The major symptom is orthostatic headache which gradually disappears after lying down. Lumbar epidural blood patches (EBPs) can be effective in relieving headaches, however, thoracic and cervical EBPs have also been applied to alleviate the symptoms. OBJECTIVE AND METHODS Retrospective colle...

BACKGROUND AND PURPOSE A combined therapy of local recombinant tissue plasminogen activator (rtPA) fibrinolysis and intravenous Abciximab platelet inhibition with additional percutaneous transluminal angioplasty (PTA)/stenting may improve recanalization and neurological outcome in patients with acute vertebrobasilar occlusion. METHODS Combined FAST therapy consisted on intravenous bolus of Ab...

The current paper presents theoretical and experimental evidence to justify the need for paying attention investment horizon. Therefore, a criterion called 'Safest Investment Horizon' (SIH) is utilized select appropriate To compute this quantity, ratio Ratio' (SIR) calculated, relationship between these criteria arbitrage opportunities, along with methods making an profit through selecting time...

Background: We present a unique case of spontaneous intracranial hypotension (SIH) presenting with acute collapse and loss consciousness. Case Description: The affected patient suffered an abrupt decline in level consciousness several weeks after initial diagnosis. was urgently transferred to specialist neurosurgical unit. Imaging showed bilateral subdural fluid collections significant associat...

sionally the patient’s chief complaints. Stupor is an unusual complication that we encountered in one patient because of a central herniation syndrome. Although CSF pressure in SIH is usually low, this is not always the case. Mokri et al noted pressures between 70 and 130 mm in four of 26 patients (2), and we observed the same range in three patients with SIH. CSF lymphocytosis between 8 and 80...

A novel unit cell for analog, dynamic, random-access memory is described. The unit cell is implemented using a charge-coupled device (CCD) and features voltage-inholtage-out operation with low power. The unit cell is essentially an algorithmic voltage sampleand-hold (SIH) circuit. It is sufficiently compact for imager frame memory application and may also find application in analog neural netwo...

The reductive amination of aldehydes or ketones using Ph(2)SiH(2) or PhSiH(3) has been effectively promoted by the direct use of Bu(2)SnClH-pyridine N-oxide as a catalyst; this method has advantages in terms of its mild conditions and wide application to various carbonyls and amines, including aliphatic examples.
