introduction: endoscopic sinus surgery is a common procedure performed by otolaryngologists. this study evaluated the efficacy of intravenous (iv) tranexamic acid (ta) on hemorrhage  in patients undergoing elective endoscopic sinus surgery (ess).   materials and methods: the present study was performed in 170 patients scheduled for ess surgery under general anesthesia in order to examine the ef...

introduction measuring magnetic induction phase shift (mips) changes as a function of cerebral hemorrhage volume has the potential for being a simple method for primary and non-contact detection of the occurrence and progress of cerebral hemorrhage. our previous mips study showed that the intracranial pressure (icp) was used as a contrast index and found the primary correlation between mips and...

subarachnoid hemorrhage (sah) resulting from a ruptured intracranial aneurysm can induce cerebral vasospasm with subsequent reduction in cerebral blood flow (cbf). the present study examines the pathological alterations in the wall of human cerebral arteries at autopsy, especially with regard to intimal pathology, following aneurysmal sah. arterial segments from the circle of willis were fixed ...

results hemostatic agents can establish hemostasis by means of different mechanisms, including concentrating coagulation factors, adhesion to the tissues, in which traumatic hemorrhage occurred, and delivering procoagulant factors to the hemorrhage site. presently, these hemostatics have been significantly improved with regard to efficacy and in adverse consequences, resulting from their use. s...

background: arteriovenous malformations are one of the most common vascular disorders of the colon. vascular disorders present as painless, high-volume rectal bleeding. case presentation: this study elucidates two rare cases of vascular disorders that are diagnosed as angiodysplasia of the left colon and cavernous hemangioma of the colon and rectum.  the chief complaint in two patients was rect...

#### Notable in Neurology This Week This issue features an article that investigates whether MRI markers of cerebral small vessel disease differ according to self-reported race or ethnicity and any differences are associated with the risk intracerebral hemorrhage; another examines effect adrenomedullin on patients migraine. A featured Views & Reviews provides recommendations outcome measures s...

Although occurance of sudden and extensive hemorrhage is not a new subject, however due to high morbidity and mortality a high level of experience and expertise is required to control the situation.Single adrenaline injction that is fast and very potent has been used in order to maintain BP and help the use of blood saved in other parts of the body.Durring 1375 to 1381 a total of 8 patients wer...

This paper presents a simplified derivation of the structure and performance of the optimum diversity comhiner/decision feedback equalizers, previously derived by Balahan and Salz. O u r analysis is based on fundamental results of linear prediction and estimation theory. New closed-form expressions that benchmark the performance of these receivers in a two-hem slowly Rayleigh fading channel hav...

Objective(s): The 5-hydroxytryptamine1A (5-HT1A) receptor is one of the serotonin receptors in the brain, which regulates cardiovascular responses, especially in hemorrhage. Presence of this receptor in the cuneiform nucleus (CnF) has been shown. The present study evaluates the cardiovascular effect of this receptor of the CnF in normal and hypotensive hemorrhagic rats...
