Background: Differential diagnosis between acute ischemic stroke (AIS) and epilepsy-related stroke mimics is sometimes difficult in the emergency department. We investigated whether a combination of diffusion-weighted imaging (DWI) and arterial spin labeling imaging (ASL) is useful in distinguishing AIS from epileptic disorders.

Methods: The study included suspected AIS patients who underwent emergency MRI including both DWI and ASL, and who exhibited DWI high-intensity lesions corresponding to neurological symptoms.

Article Synopsis
  • - A rare case of acute liver injury was reported in a 41-year-old man following treatment for internal hemorrhoids using a submucosal injection of aluminum potassium sulfate and tannic acid (ALTA) combined with lidocaine.
  • - The liver injury was identified as hepatocellular and cholestatic, but the exact mechanism behind the injury couldn't be determined; high levels of eosinophils and immunoglobulin E were noted, while a lymphocyte stimulation test returned negative results after 25 days.
  • - The patient's liver condition improved significantly after two weeks of fluid replacement therapy, highlighting the need for further analysis of similar cases in the future as this is the first reported severe liver disorder linked to ALTA treatment.

Unlabelled: Abstract

Background And Purpose: Patients with severe intracranial hemorrhage (ICH) often develop infectious complications during the acute stage. Animal experiments have demonstrated that enteral immunonutrition with a dietary fluid containing whey peptide (WP) enhances immunoactivity and prevents infection. The aim of the current study was to investigate the infection control effect of WP in the clinical management of patients with severe ICH.

Brain hypoxia or ischemia causes acidosis and the intracellular accumulation of Ca(2+) in neuron. The aims of the present study were to elucidate the interaction between intracellular pH and Ca(2+) during transient acidosis and its effects on the viability of neuronal and glial cells. Intracellular Ca(2+) and pH were measured using the fluorescence of fura-2 and 2',7'-bis(2-carboxyethyl)-5(6)-carboxyfluorescein acetoxymethyl ester in neuroblastoma (IMR-32), glioblastoma (T98G), and astrocytoma (CCF-STTG1) cell lines.

Background And Purpose: Lymphotoxin alpha (LTA), one of the tumor necrosis factor family proteins, is an important proinflammatory cytokine and appears to play a putative role in the inflammatory process of atherosclerosis. Recent genetic studies have suggested that variations in the gene encoding LTA, which affect its expression and biological function, may contribute to the development of vascular diseases. We conducted a case-control study to clarify the association of LTA gene polymorphisms with ischemic stroke in a large Japanese population.

The central nervous system (CNS) pericytes play an important role in brain microcirculation. Na(+)/H(+) exchanger isoform 1 (NHE1) has been suggested to regulate the proliferation of nonvascular cells through the regulation of intracellular pH, Na(+), and cell volume; however, the relationship between NHE1 and intracellular Ca(2+), an essential signal of cell growth, is still not known. The aim of the present study was to elucidate the role of NHE1 in Ca(2+) signaling and the proliferation of human CNS pericytes.

We report a patient with dissection of the bilateral intracranial vertebral artery (VA) that did not present any symptoms other than occipital headache, which was probably associated with sleeping overnight in a car seat with unsteady head position. Although cerebral angiography revealed extensive dissection of the bilateral VA after branching of the posterior inferior cerebral artery, retrograde flow to the basilar artery (BA) via the right posterior communicating artery contributed to preserved posterior circulation. These findings indicate that even in patients without neurological deficits, the involvement of BA cannot be excluded and that accurate evaluation using radiological techniques should be considered.

Several infectious agents, such as Chlamydia pneumoniae, cytomegalovirus (CMV), herpes simplex virus (HSV), and Helicobacter pylori, have been implicated in the pathogenesis of atherosclerosis; however, but the contribution of infection may vary among races and geographic conditions. The present study investigates the association between the presence of these pathogens and carotid atherosclerosis and examines the relevance of an infectious burden during atherogenesis in Japanese patients undergoing carotid endarterectomy. We investigated a total of 50 carotid atherosclerotic plaques resected during carotid endarterectomy by polymerase chain reaction (PCR) for C.

An unruptured intracranial aneurysm is an uncommon but possible embolic source to the brain. We report a young patient who developed recurrent ischemic strokes occurring mainly in the left internal carotid arterial territory within a short interval; the first stroke occurred midway through a long-distance race, and the second stroke occurred immediately following a bowel movement. The angiographical contrast deficit indicated a thrombus in the left anterior cerebral artery as a result of the embolism.
