Hypoglycemic injury in the mature brain is mediated by excitotoxicity, which is worsened by disordered cellular energy metabolism. The role of excitotoxicity in relation to brain energy metabolism during hypoglycemia has not been studied in the immature brain. Brain oxygen consumption ([Formula: see text]) increases during hypoglycemia in piglets, whereas [Formula: see text] decreases in adult ...

Objectives: We here assessed the effects of left dorsolateral prefrontal cortex transcranial direct current stimulation (DLPF-tDCS) on Coma Recovery ScaleRevised scores in severely brain-damaged patients with disorders of consciousness. Methods: In a double-blind sham-controlled crossover design, anodal and sham tDCS were delivered in randomized order over the left DLPF cortex for 20 minutes in...

Three cases of coma after vincristine therapy are described. One patient had hyponatraemia and other features of inappropriate secretion of antidiuretic hormone. The effects were temporary, and full recovery occurred in all three patients.

Extreme temperatures restrict the performance of terrestrial arthropods and variations in low temperatures on a latitudinal scale influence physiological variables. Recovery time from chill coma is a measure of cold tolerance and it is a good index of climatic adaptation. We tested differences in recovery time of the common woodlouse (Porcellio laevis) exposed to different thermal conditions. I...

BACKGROUND γ-Hydroxybutyrate (GHB) is a drug of abuse with dose-dependent sedative effects. Systematic data on the acute toxicity of GHB from emergency department (ED) presentations over a long period of time are currently missing from the literature. The present study described the clinical features of GHB toxicity. METHODS Retrospective case series of GHB intoxications seen in an urban ED. ...

This study aimed to observe the clinical curative effect of penehyclidine hydrochloride (PHC) combined with hemoperfusion in treating acute severe organophosphorus pesticide poisoning. We randomly divided 61 patients with severe organophosphorus pesticide poisoning into an experimental group (N = 31) and a control group (N = 30), and we compared the coma-recovery time, mechanical ventilation ti...

To determine if the elevated transferrin saturations found in some patients with severe malaria are associated with an adverse outcome in cerebral malaria, we retrospectively measured baseline saturations in stored serum samples from 81 Zambian children with strictly defined cerebral malaria. The children had been treated with quinine, sulfadox-ine-pyrimethamine, and intravenous infusions of ei...

Prolonged coma resulting from hypoxic brain injury is usually associated with a dismal chance of return to independent existence. In this report a case is described of a 60 year old man who recovered and returned to work as a university professor after being in a vegetative state at least 8 weeks after a prolonged cerebral hypoxic event.
