Myeloscopy has been undertaken in a series of 208 patients without any serious complications. Observations have been made of changes in blood flow in the vessels accompanying the cauda equina during Lasègue's test and in some pathological states. Direct observation of the nucleus pulposus has been achieved and the possibility of the removal of herniated disc material by use of the myeloscope is suggested.

In 1952, Albright for the first time found Pseudo-Pseudohypoparathyroidism (P. P. H.), as a syndrome of anatomic anomalies similar to Pseudohypoparathyroidism (namely, short stature, round face, short metacarpal or metatarsal bone and ectopic ossification), with normal serum concentration of calcium and phosphate. Since 1952, many cases were reported all over the world. But we have never seen the report in Japan. Recently, we have experienced a young girl (10 years) who had characteristics for P.P. H. with suggestive, familial occurrence. This case is presented and the nomenclature of related clinical entities was discussed together with the statistics of P. P. H. in literature.

Two cases of acquired spondylolysis are reported, and the etiology of the condition is briefly discussed. The cause seems to be a combination of predisposition and stress.
