ABSTRACT
The authors relate upon the so-called Boerhaave's syndrome or spontaneous perforation of the esophagus illustrating 2 cases recently observed. On the basis of their experience and of what has been reported by the literature on this subject the etiopathogenetic and pathophysiologic problems as well as the adequate treatment are debated. Particularly the nature of the lesion, which is a barotrauma lesion, the urgency of the surgical treatment, and the severity of the prognosis are pointed out.

Estrogen and progesterone receptors were studied in 70 cases of human colorectal cancer by a cytochemical technique. 28.5% of the cases were estrogen-receptor positive and 42.8% progesterone-receptor positive. There was no difference between the sexes for estrogen receptors but the women had more tumours with progesterone receptors than men. The presence of receptors is unrelated to the differentiation of the tumor. More colon tumours were positive than those of the sigma and rectum. The concentration of cells with receptors in positive cancer cases tended to be low or medium-low.
