Does access to general dental treatment affect the number and complexity of patients presenting to the acute hospital service with severe dentofacial infections?
The primary cause of infection was dental caries in all patients. Dental caries is a preventable and treatable disease. Increased resources should be made available to support access to dental care, and thereby lessen the potential for the morbidity and mortality associated with serious odontogenic infections. The study at present continues as a prospective study.
Loss of the blood flow response to hypercapnia during acute hyperammonemia is not due simply to swollen astrocyte processes passively impeding blood flow because extraparenchymal resistance arterioles also lose their reactivity selectively to hypercapnia. Lost reactivity depends on glutamine synthesis rather than on ammonium ions per se and may reflect indirect effects of astrocyte dysfunction associated with glutamine accumulation or possibly effects of glutamine on nitric oxide production.
