Spontaneous pituitary apoplexy with transient panhypopituitarism and diabetes insipidus.

A 40-year-old patient presented with intractable headache, panhypopituitarism and diabetes insipidus 5 months after a severe shock syndrome. The magnetic resonance imaging of the brain confirmed a hemorragic necrosis of the pituitary gland. On follow-up, the patient recovered a normal pituitary function, except for the persistence of a partial ACTH deficiency. The pituitary image also normalized. Pituitary apoplexy is a rare disease of severe prognosis due to its neurological and endocrine consequences. It can now be more easily recognized by the new imaging techniques.

HBs antigen in human plasma fractions.

Therapeutic fractions were obtained by fractionating human plasma containing HBs antigen, by the Cohn ethanol technique modified by Nitschmann. Plasmas with various HBs antigen titers were selected. The antigen was sought in each fraction by the techniques of counterelectrophoresis and radioimmunological detection in liquid phase. With the exception of very pure albumins, all fractions were found to contain the HBs antigen, though in variable proportions. A technique for the purification of albumin, applicable on an industrial scale, is proposed. It makes it possible to obtain an albumin fraction in which the HBs antigen cannot be detected by the most sensitive techniques, even starting with a plasma which is very rich in HBs antigen (titer 1/64 by counterelectrophoresis).
