[Lumbar spondylolisthesis and nerve-root compression. Surgical experience with 19 cases without spinal fusion (author's transl)].

The clinical picture presented by cases of lumbar Spondylolisthesis with radicular symptoms appears to be due to displacement of the intervertebral disc. In spondylolisthesis of the fourth lumbar vertebra the fourth and/or the fifth roots are involved, in slipping of the fifth vertebra the fifth lumbar and/or the first sacral roots. The mechanisms of the radicular involvement are discussed. Surgical treatment entails decompression of the nerve roots by a less destructive method than Gill's (6, 7) without spinal fusion. The results are satisfactory.

[Narrowness of the recessus lateralis in the lumbar region of the spine as cause of the nerve-root compression in narrowing of the intervertebral discs (author's transl)].

The intense radicular pain of sciatica may result from nerve root entrapment in a narrowed lateral vertebral recess without discal herniation. In such cases relief of pain is achieved by unroofing the lateral recess and excising the overhanging portion of the superior articular facet, without removing the disc. The narrowing of the lateral recess is congenital, but the compression of the root occurs first in adult life. The thinning of the disc causes backward displacement of the vertebral body above and forward displacement of the cranial articular facet of the vertebral body below the thinned disc. In a large lateral recess such subluxation does not cause any entrapment of the root. If the lateral recess is congenitally narrowed the root is tightly wedged laterally and sometimes can be decompressed only by a complete arthrotomy. The same entrapment can occur as a consequence of removing of a disc (pseudorecurrence).

Subdural interhemispheric empyema in a 7-year-old boy.

Subdural interhemispheric empyema was diagnosed by angiography and computerized tomography (CT) in a 7-year-old boy suffering from acute left hemiparesis. After neurosurgical intervention his condition improved. Peptostreptococcus intermedius was cultured from the empyema. One year after hospitalisation the boy is in good condition. The importance of the CT-scanning for diagnosis and management of brain abscess or empyema is stressed.

[Statistical evaluation of vectorcardiographic criteria for the diagnosis of posterior myocardial necrosis (author's transl)].

85 vectorcardiograms, characterized by anteriorly oriented horizontal ventricular loop, were analized in order to evaluate if this pattern can be considered diagnostic at all for strictly posterior myocardial infarction. Records were divided into two groups according to positivity or negativity of clinical history for myocardial infarction. Records consistent with right ventricular hypertrophy were ruled out. Nine parameters related to ventricular depolarization and repolarization were measured and the values were submitted to statistical analysis. The study showed that:--selection of the two groups was correct, because of first group's homogeneity and control group's unhomogeneity;--mean values of the nine parameters did not differ significantly in the two groups;--single parameter into each group was unrelated to others. As a consequence, criteria at the time in use for diagnosis of strictly posterior myocardial infarction seem not to be useful, as other conditions beside myocardial infarction or right ventricular hypertrophy are able to determine the same vectorcardiographic pattern.
