Called also adiponecrosis neonatorum or subcutanea.
Zenker's necrosis hyaline degeneration and necrosis of striated muscle; called also Zenker's degeneration.

Sheehan's syndromeThe effects of destruction of the front part of the PITUITARY GLAND by loss of its blood supply (infarction) following severe bleeding from the womb after delivery of a baby (postpartum haemorrhage). There is failure of milk production, loss of body hair, absence of menstruation, lethargy and other effects of underaction of the endocrine glands. (Professor Harold Leeming Sheehan, 1900–86, English physician).
