Investigation reveals meth fueled accidental shooting. New philadelphia (wjer) - police have finished vitamin investigating a shooting incident last week that left one man with a lower leg wound. . Detective captain Shawn Nelson says a couple suspects broke in to a home in the 700 block of North Broadway and stole a safe Thursday. They took it to an apartment down the road in the 400 block. . Nelson says thats where a 25-year old Frank heldt of New Philadelphia admitted to taking a gun from the safe and accidentally shooting himself while high on meth. Some of the six people in the apartment at the time also backed that story. Nelson says the safe was stolen from the parents of one of the other suspects. Heldt was released from an Akron hospital and later taken to the tuscarawas county jail for a parole violation.

Since no arterial input function was available, only relative regional measurements were obtained. Although rmtt calculations cannot be performed without a complete understanding of the topology of the vasculature (11), important information about tissue perfusion is provided by rmtt calculations, especially when corresponding hemispheres are compared. Because of susceptibility effects, signal intensity drops as the contrast material reaches the tissue and corresponds to relative tissue perfusion. A plot relaxivity ( ) or versus time is the first step in quantitative analysis and is assumed to be directly proportional to the concentration-time curve. Where, sI ( t ) is the signal intensity at time t, and, sI 0 is the signal intensity before the arrival of contrast material. Si 0 was calculated as the average signal intensity over the first four images. A least-squares optimization to fit a four-parameter γ variate model of the versus time curve ( equation 2 ) (11) was then determined.

By using echo-planar perfusion imaging (eppi) techniques, multisection images can be readily obtained to cover the symptomatic brain within a very short time frame (810), which is essential for feasibility within the clinical setting. Our purpose was to assess the usefulness of eppi in the detection and evaluation of the underlying hemodynamic compromise boeken in patients with severe stenosis or occlusion of the carotid artery who had experienced either a recent transient ischemic attack (TIA) or minor stroke. Methods, patients, eleven patients (two men and nine women) aged 41 to 84 years (mean age, 61 years) with severe stenosis or occlusion of the carotid artery who had experienced either a recent tia or minor stroke were studied. All patients underwent angiography, which demonstrated unilateral occlusion of the internal carotid artery (ICA) (n 3 unilateral stenosis of the ica (n 5 bilateral occlusion of the ica (n 2 or unilateral occlusion of the anterior cerebral artery (ACA) (n 1). Cerebral angiography was performed within 8 hours of the perfusion mr study.

Patients' symptoms, usually tia or minor stroke, are summarized. Table 1: Data for 11 patients with chronic cerebral ischemia. Mr studies, mR studies were performed on.5-t mr unit retrofitted for echo-planar imaging (EPI) capabilities. Axial T1- and T2-weighted standard spin-echo sequences were obtained before eppi with imaging parameters of 600/20/1,2 (TR/TE/excitations) for T1-weighted images and 20002500/30,90/1,2 for T2-weighted double-echo images, with a section thickness of 5 mm, a matrix of 256 192, and a field of view. Dynamic spin-echo epi susceptibility-contrast images were obtained with 8 to 10 axial sections at 2-second intervals for 60 seconds with imaging parameters of 2000/100/1, a field of view of 20 40, a acquisition matrix, single shot. Approximately four to five images per section were obtained before the start of an iv bolus cider injection (9 mL/s).1 mmol/kg of gadopentetate dimeglumine using an mr-compatible power injector. The theory of nondiffusable tracers was applied to these data.

Two mechanisms of cerebral lump ischemia in this disease have been identified: vascular occlusion from an embolism or propagating thrombus from an atherosclerotic plaque of the carotid artery (artery-to-artery embolism and watershed or border-zone ischemia caused by critically reduced perfusion pressure (hemodynamic stroke). Insufficient collateral circulation may cause a critical reduction in cerebral blood flow (CBF) and an increased risk of hemodynamic stroke. It is well known that hypoperfused tissue under chronic hemodynamic stress may undergo compensatory changes, which can be difficult to diagnose with conventional ct or mr imaging (2) non in patients who are also at increased risk for a major stroke (3). Therefore, a noninvasive and convenient means to detect and evaluate the underlying hemodynamic compromise in symptomatic patients with severe stenosis or occlusion of the carotid artery may be helpful in the diagnosis and management of this common disease. Technological advances have made it possible to obtain direct and more accurate measurements of the regional hemodynamics of brain tissue, such as regional cbf and regional cerebral blood volume (CBV) by using positron emission tomography (pet however, this type of hemodynamic information has not been. In addition, pet cannot provide prompt information, making it impractical in the management of acute stroke. Recently, the development of perfusion mr imaging has made the rapid assessment of cerebral hemodynamics possible (410). Although this method, unlike pet, cannot provide absolute measurements of cbv or cbf, it can offer a semiquantitative assessment of relative cbv (rCBV) and vascular mean transit time (rMTT) more promptly than with pet.

Methods: Spin-echo echo-planar perfusion imaging was performed in 11 patients (two had bilateral disease) with severe stenosis or occlusion of the carotid artery who had experienced either a recent transient ischemic attack or minor stroke. Relative cerebral blood volume (rCBV) maps and relative mean transit time (rMTT) maps were generated from the time-concentration curve. Findings on T2-weighted images, angiograms, rcbv maps, and rmtt maps were compared and assessed qualitatively and quantitatively. Results: Although the abnormalities on T2-weighted images were absent, minimal, and/or unrelated to the degree of stenosis or collateral circulation, rmtt maps showed much larger and more distinct perfusion abnormalities along the vascular distribution of the affected vessels in all 13 vascular territories of the. Despite obvious abnormalities on rmtt maps, none of the patients had evidence usb of decreased rcbv in the affected brain tissue (increased in three, normal in eight). A statistically significant difference in rmtt values was found between the affected and unaffected brain tissue, whereas no significant difference was seen in rcbv values. Conclusion: Echo-planar perfusion imaging is a noninvasive and rapid method for evaluating the hemodynamics in severe occlusive carotid artery disease and the compensatory vascular changes, and it may be useful in patient management. The cerebral hemodynamic status of patients with severe occlusive carotid artery disease has been reported to play a significant role in the occurrence of stroke (1).


A sudden loss of brain function caused by a blockage or rupture of a blood vessel that supplies the brain, characterized by loss of muscular control, complete or partial loss of sensation or consciousness, dizziness, slurred speech, or other symptoms that vary with the extent. The most common manifestation is some degree of paralysis, but small strokes may occur without symptoms. . Usually caused by arteriosclerosis, it often results in brain damage.

Century ride raises funds for path development. Undated (wjer) - some of the most frequent users of the towpath Trail are doing thrombophlebitis what they can to make its extension a reality. . 128 bicyclists rode 101 miles from Cleveland to south of zoar down the towpath, and then along State route 800 into new Philadelphia earlier this month for the 9th annual Huntington Towpath Century ride. Coordinator Gabe riggle says they raised 161,000 through this to fund continued development of the trail by attracting grants. Riggle says they were some serious riders. Riggle says the goal is to still have the towpath reach New Philadelphia by 2020. . There are still some other stretches that need finished, like the bolivar-Stark county connection, and from State route 800 into dover and Phila.

Sheriff, issues the naked truth to driving without clothes. New philadelphia (wjer) - tuscarawas countys sheriff has some answers following a state story where a naked man was driving the wrong way on 77 near Akron and then tried to run from police. Orvis Campbell says technically, the driving naked part wouldnt be a crime, if its concealed. However something like that would seem difficult to hide. Campbell says if caught, Ohio indecency law violations could range from a fourth degree misdemeanor to a higher felony if there are kids affected.

    Introduction Cerebral watershed (or border zone) infarcts (WI) involve the junction of the distal fields of two non-anastomosing arterial systems, which are hemodynamic risk zones. A watershed stroke is defined as an ischemia, or blood flow blockage, that is localized to the border zones between the territories of two major arteries in the brain. I cared for my post- stroke father from age 92 to 94, two reasonably good years for him, and then made conscious decision (based, of course, on what he had told me earlier) to let him go after 4 pneumonias and much deterioration.

    A watershed stroke or watershed infarct is defined as an ischemia, or blood flow blockage, that is localized to the border zones between the territories of two major arteries in the brain. Watershed locations are those border-zone regions in the brain supplied by the major cerebral arteries where blood supply is decreased. Key words: watershed infarct, carotid atherosclerosis, carotid ultrasounds, diffusion-weighted Magnetic Resonance.

    Symptoms and diagnosis of, watershed, strokes The watershed regions of the brain may be affected by a decrease of blood flow, which may result in a stroke. The symptoms of a watershed stroke include weakness and/or vision loss on the right or the left side of the face, arm or leg. A watershed stroke or watershed infarct is defined as a brain ischemia that is localized to the vulnerable border zones between the tissues supplied by the anterior, posterior and middle cerebral arteries. The actual blood stream blockage/restriction site can be located far away from the infarcts.
