Spontaneous perforation of the small intestine in the newborn is rare. In most cases the etiology is unknown. Three cases of perforation in preterm newborn infants are described. The clinical diagnosis was necrotizing enterocolitis (NEC), and an urgent laparotomy was performed. The histologic examination was compatible with the diagnosis of a congenital defect of the intestinal musculature. All three infants survived.

We examined the central nervous system of a 67-year-old man who showed symptoms of lathyrism after being imprisoned at age 35 and fed on a diet of chick peas, Lathyrus sativus. The most obvious changes were loss of axons and myelin in the pyramidal tract in the lumbar spinal cord. These alterations correlated with spastic paraparesis. Other changes at the same level were a mild degree of degeneration of anterior horn cells. Pallor of Goll's tracts and axonal swelling in Goll's nuclei were also observed. A few examples of senile plaques and neurofibrillary tangles were observed in Ammon's horn.

SYNoPSIS A case of diffuse intravascular clotting associated with a primary brain tumour (oligodendroglioma) is described. The mechanisms of clotting and subsequent fibrinolytic syndromes are discussed with reference to the literature. On the basis of clinical, laboratory, and postmortem findings the possibility of the induction of diffuse intravascular clotting by primary brain tumours is stressed.
