Case ReportsFusobacterium necrophorum-induced sepsis: an unusual case of Lemierre's syndrome.
Classical Lemierre's syndrome is characterized by severe sepsis with metastatic abscess formation in young, previously fit people from a primary head or neck focus. The causative organisms are the anaerobic fusobacteria, most commonly Fusobacterium necrophorum. We describe the evaluation, therapeutic interventions and management of a patient with Lemierre's syndrome who presented in septic shock with multiple organ dysfunction. ⋯ This case highlights the need to raise the awareness of 'the forgotten disease': Lemierre's syndrome. Its diagnosis may, as in this case, be confounded by a lack of symptoms of pharyngitis at the time of presentation, and end-organ dysfunction associated with severe sepsis, possibly suggesting an alternative source of infection. As appropriate antibiotics reduce mortality dramatically, clinicians need to be alert to Lemierre's syndrome and include it in the differential diagnosis in young but otherwise healthy patients presenting with severe sepsis.

Comparative StudyEffect of Xenon on elevated intracranial pressure as compared with nitrous oxide and total intravenous anesthesia in pigs.
Xenon in low concentrations has been investigated in neuroradiology to measure cerebral blood flow (CBF). Several reports have suggested that inhalation of Xenon might increase intracranial pressure (ICP) by increasing the cerebral blood flow and blood volume, raising concerns about using Xenon as an anesthetic in higher concentrations for head-injured patients. A porcine study is presented in which the effects of inhaled 75% Xenon on elevated ICP, cerebral perfusion pressure and the efficacy of hyperventilation for ICP treatment were compared with nitrous oxide anesthesia and total intravenous anesthesia (TIVA). ⋯ During Xenon anesthesia, elevated ICP is not increased further and is partially reversible by hyperventilation. Our study suggests that inhalation of 75% Xenon seems not to be contraindicated in patients with elevated ICP.
