Combined therapy of thoracic esophageal cancer.

High rates of esophageal cancer in advanced stages and poor short- and long-term results with surgical treatment have led to the use of combined treatment regimens. There is, however, no unanimity as to the most effective preoperative therapy or the most effective therapeutic tactics. In combined therapy we are in favor of strict compliance with the sequence of abdominal exploration, radiotherapy, and finally surgery.

Biochemical study of sialidosis type I in a Russian family.

A 7-year-old boy from a Russian family with decreased vision and a cherry-red spot but without any somatic and mental abnormalities is described in this paper. The decreased neuraminidase activity in the child's leukocytes and cultured skin fibroblasts and his 10-fold increase in urinary sialyloligosaccharides allowed us to conclude that he was affected by type I sialidosis. Some other results of the biochemical study of this child and his parents are presented.
