[Reactive osseous changes in intracranial types of meningioma (author's transl)].

Reactive osseous changes are so characteristic of meningiomas that diagnosis of meningioma is not infrequently possible by merely x-raying the cranium. The x-ray film shows flat or bed-like growing intracranial types (meningioma en plaque) which occupy little space or none at all, where the skeletal changes are most prominent. This type of meningioma escapes contrast medium diagnosis and is positive only in the conventional x-ray of the cranium or - in the state of beginning spread - in the tomogram.

Cerebrospinal fluid scintigraphy and computer assisted tomography in the evaluation of special kinds of hydrocephalus in children.

CT cisternography and CSF scintigraphy are indispensable in the detailed morphologic and etiologic evaluation of special types of childhood hydrocephalus. In addition these investigations afford interesting insights into CSF dynamics in apparently complete membranous or tumorous obstruction of the fourth ventricle and into the genesis of internal hydrocephalus in cerebellopontine angle tumors.

[Computer tomographic and scintigraphic aspects of subdural haematomas (author's transl)].

Cerebral computer tomography in cases of emergency is undoubtedly superior to conventional neuro-radiological methods. The changes during resorption of intracranial bleeds, which are due to their particular physical properties, can supply valuable diagnostic information, but under particular circumstances they may obscure the diagnosis. The diagnosis and differential diagnosis of subdural haematomas may become difficult during the isodense phase. Hyper- and hypo-dense collections of fluid may also be missed unless note is taken of subtile indirect signs and special techniques are used. At the same time, the value of cerebral scintigraphy is emphasised. Valuable information may be expected from early scans (10 to 15 minutes after injection). In this way even shallow, bilateral subdural haematomas can be demomstrated during the acute and sub-acute stage. The degree of uptake depends on the histology of the capsule of the haematoma.

[Comparison of the results of computer tomography and isotope diagnostics in pathologic processes of the infratentorial range (author's transl)].

1. Computer tomography is much more clearly superior to cranial scintigraphy with regard to the identification and localization of pathologic infratentorial processes, than in the supratentorial range. 2. Computer tomography alone solves many diagnostic problems relating to the infratentorial range, but it cannot by any means solve all the problems. 3. The diagnosis identifying the kind of infratentorial growing and displacing tumors cannot be safely established either by computer tomography alone or by a combination of computer tomography and cranial scintigraphy. 4. Cranial scintigraphy and CSF scintigraphy can supply additional informations, support the diagnosis, or contribute towards establishing the final diagnosis, in cases where computer tomography alone supplies ambiguous, questionably positive or discrete answers. In such cases, the emphasis is on the etiologic grouping of unclear forms of hydrocephalos.

Physical exercise after induced alkalosis (bicarbonate or tris-buffer).

The influence of bicarbonate and Tris-buffer infusions on the performance capacity for maximal, brief exercise (400 m run) was studied using 10 normal males in their twenties. Run time, maximal lactate concentration and heart rate remained unchanged after the buffer infusions. As a result of the induced elevated buffering capacity, the average pH after exercise was about 0.1 unit higher. Corresponding values for base excess and standard bicarbonate were found. The arterial pCO2 was higher after infusion as a result of the active respiratory compensation. Since the reduction in the work-related metabolic acidosis by the buffering substances caused no improvement in performance, the importance of pH as the performance-limiting factor must be questioned because the investigation gave no evidence for alterations of intracellular pH.
