Case Reports[CT findings of a cerebral air embolism as a consequence of an accidental subclavian catheter disconnection].
This report describes the definitive diagnosis of cerebral air embolism following accidental disconnection of a subclavian catheter by documentation of cranial CT's. We also discuss critically the pathophysiology of cerebral air embolism and its differentiation from "the bends". The necessity of recognising this entity is important in differential diagnosis. The pathophysiology of air embolism is discussed.

Case Reports[Massive natriuresis and polyuria after triple craniocervical subarachnoid hemorrhage: cerebral salt wasting syndrome?].
A thirty-year-old male patient suffered subarachnoidal haemorrhage from an angioma positioned in the cranio-cervical transition. After rebleeding twice the patient developed a hydrocephalus internus malresorptivus and excessive natriuresis and polyuria, accompanied by depressed renin activity and extremely low aldosterone plasma levels. Neither fluid restriction and sodium substitution, nor administration of hydro-chlorothiazide/indomethacin affected natriuresis and polyuria. ⋯ Similar disturbances have been reported from other patients with intracranial disorders. Mechanical pressure exercised on the hypothalamus might cause the disturbance of fluid and sodium balance. Assuming a cerebral salt wasting syndrome, a putative natriuretic factor coming from the brain or an imbalance in the cerebral renin-angiotensin-system, as described in rats and dogs, must be discussed.
