PURPOSE Electrical Bioimpedance Cerebral Monitoring is assessment in real time of health of brain tissue through study of passive dielectric properties of brain. During the last two decades theory and technology have been developed in parallel with animal experiments aiming to confirm feasibility of using bioimpedance-based technology for prompt detection of brain damage. Here, for the first ti...

Exposure to complex mixtures of air pollutants produces inflammation in the upper and lower respiratory tract. Because the nasal cavity is a common portal of entry, respiratory and olfactory epithelia are vulnerable targets for toxicological damage. This study has evaluated, by light and electron microscopy and immunohistochemical expression of nuclear factor-kappa beta (NF-kappaB) and inducibl...

In contrast to traditional textbook paradigms, recent studies indicate neuronal damage in classic neuroinflammatory diseases of the brain, such as multiple sclerosis or meningitis. In these cases, immune cells invade the central nervous system compartments, accompanied by a massive breakdown of the blood-brain barrier and typical changes of the cerebrospinal fluid. On the other hand, inflammati...

193 Electroconvulsive therapy (ECT) is a very controversial treatment. It is a topic for which it is difficult to obtain an objective perspective because emotional undercurrents tend to run strong. It may, in this respect, be comparable to other 214 emotionally laden issue? such as ethnic differences in IQ and the bad effects of marijuana. Friedberg (1977), an outspoken critic of ECT, attribute...

A 29-year-old man presented with comatose after methadone intoxication. Cerebral tomography only showed cortico-subcortical hypodense signal in the right cerebellar hemisphere. Brain MRI showed a rare imaging of FLAIR and DWI hyperintensities in the two cerebellar hemispheres as well as basal ganglia (globi pallidi), compatible with methadone overdose. To our knowledge this is the first reporte...

The central question to be addressed in this review can be stated as "How does hypoglycemia kill neurons?" Initial research on hypoglycemic brain damage in the 1930s was aimed at demonstrating the existence of any brain damage whatsoever due to insulin. Recent results indicate that uncomplicated hypoglycemia is capable of killing neurons in the brain. However, the mechanism does not appear to b...

he critical issues in the clinical management of sports concussion include confirming the diagnosis, excluding structural abnormality and determining when players can be safely returned to competition. Despite the apparent simplicity of this process, the management of this one injury seems to provoke more debate than all other sports injuries combined. Unfortunately, this debate has largely bee...

Cerebellar syndromes and radiologic cerebellar atrophy after hyperpyrexia have occasionally been reported, mostly in neuroleptic malignant syndromes, but neuropathologic studies are extremely rare. We studied 3 patients (a 74-year-old woman, a 63-year-old man, and an 80-year-old man) who had heat stroke during heat waves in France. One patient had generalized seizures and died 28 hours after ad...

the purpose of this study was to examine the likelihood of brain damage in shell shock injured patients by comparing their cognitive functioning with three groups of injured patients, prisoner of was with ptsd, and normal individuals.all groups were administrered wchsler memory scale, benton visual etention, dailler cancellation, smith digit symbol and wisconsin card sorting tests. the findings...

Background: Probiotics are microorganisms that may influence brain function via altering brain neurochemistry. New research evidence suggests that probiotic bacteria might protect tissue damage through diminishing the production of free radicals and/or inflammatory cytokines. Therefore, this study was designed to evaluate the effects of probiotic bacteria on the prevention or reduction of brain...
