[The clinical significance of ventricular enlargement and cortical atrophy in computed tomography of the brain (author's transl)].

The diagnosis of atrophy of the brain based on the visual interpretation of CT findings appears questionable. In 56 patients there was no correlation between the CT findings of enlarged ventricles and sulci and clinical findings of psychoorganic syndromes. Only the group of 60 to 80 year old patients showed a statistically significant correlation between psychoorganic findings and the area of the lateral ventricles - measured planimetrically - and the diameter of the cella medica, but not the group of the 40 to 60 year old. There was no relationship between the number of cortical sulci and psychopathology. The morphological findings of ventricular enlargement and cortical atrophy in CT - even with exact measurements - do not allow any conclusions in regard to psychoorganic findings.

[Adie's syndrome from a neurological standpoint (author's transl)].

The findings in 22 examinations of tonic pupils, 15 of which presented Adie's syndrome, are described. The neurological and chemical as well as liquor analyses are normal except for the well known tendon reflex anomalies. Neurophysiologically, in 7 of 10 examinations mild disruptions in the sensory nerve conduction velocity were observed. The literature of the last 10 years, where it is of interest from a neurological standpoint and where it relates to the site of damage or to the origin of the tendon reflex abnormalities in Adie's syndrome, is discussed. Adie's syndrome is interpreted as damage to the peripheral nervous system in a polyneuropathic form.

Neuroradiological diagnosis of intraspinal tumors in children.

In the diagnosis of spinal and intraspinal space-occupying processes great importance attaches to radiologic plain film diagnosis, including special projections and tomography. Using refined evaluation methods, direct and indirect signs of tumors can be demonstrated in 30-50% of cases. Of decisive importance is the myelographic examination. It permits the determination of the exact localization and the size of a tumor. Contrast studies frequently allow an identification of the tumor type. Spinal arteriography and phlebography, on the other hand, are of secondary importance in the diagnosis of tumors of both spinal canal and spinal cord. In patients with bone infiltration they accomplish a valuable contribution to determine whether this expansion is directed towards the epidural space or the soft tissue structures of the back.

[Cervical myelography with water-soluble contrast medium (Metrizamide). Technique and preliminary results (author's transl)].

Use of a water-soluble contrast medium for cervical spinal diagnosis has become possible with the introduction of Metrizamide (Amipaqque). Injection of contrast at the C.1/2 level by a lateral approach results in excellent visualisation of the cervical theca with previously unobtainable detail. This technique, which is so far not well known, allows a rapid examination and when used with the new, well tolerated contrast media provides optimal diagnostic results.

[Experience with e new water soluble contrast medium for lumbar myelography (author's transl)].

Meglumin-Iodrinat has been synthesized as the contrasting part of Myelografin by Schering AG. and tested for lumbar Myelography in animal experiments. The excellent neural and general compatibility justified a first clinical trial. 200 patients were examined, 100 each with following upright or lying down positions. There were no local symptoms, no signs of spinal or cerebral irritation. This is seen to be the main advantage compared with drugs used so far. Intensity of contrast corresponded with that of Conray 60 and Dimer X. The most common complaints like headache and nausea were interpreted as CSF hypotension and can be clearly reduced by lying down. Also the concentration of the contrastmedium diminishes more rapidly with the patient lying down.

[Radiation late damage of the thoracic marrow after irradiation in the thoracic region (author's transl)].

A report is given about radiation late damage on the thoracic marrow, basing on the case histories of 100 patients irradiated in the mediastinal region with telegamma from a 60 Cobalt or 137 Caesium source between 1959, January 1st and 1972, december 31st. 77 patients were followed up during 18 months after the radiotherapy was ended; in 3 of them (equal to 4 p.c.) a radiation-induced myelopathy was found. These 3 cases were suffering from Hodgkin's disease, whereas in none of the patients with bronchial carcinoma--in spite of markedly higher radiation doses--any late damage was observed. Therefore, in irradiation of the mediastinal region, the exposure of the spinal marrow should be reduced, although the dose alone is not decisive for the development of a radiation myelopathy.
