Information-theoretical error analysis of a form-comparison test]

An attempt has been made to make an error analysis, by both the conventional and information theoretical mode of evaluation, of the results of a forms comparison test used for diagnosing the sensory and optical capacity of differentiating. A total of 423 test subjects were available for this program. Data for the standardization of this test and for the evaluation of test results was derived from the results of this investigation.     

The use of nitrous oxide as a contrast medium during fractionated gas encephalography in halane-nitrous-oxide anesthesia]

40 children were employed as test cases in fractionated gas encephalography using Halan-nitrous oxide anesthesia, and the level of cerebrospinal pressure, the r?ntgenoparent quality of the extracerebral spaces and the duration of postencephalographical symptoms were examined using air and nitrous oxide as contrast media. In the course of the examination the cerebrospinal pressure showed a tendency to rise when air was introduced, to fall when nitrous oxide was introduced. After instillation of N2O however the filling of the subarachnoid space was over so quickly that it could not be included in the assessment. Sufficient r?ntgenograms were obtained for all diagnostic demands through 'hybrid filling', (introduction of nitrous oxide into the ventricles, introduction of air into the subarachnoid spaces). With the aid of the results obtained from this examination attempts will be made to derive differentiated indications for filling with nitrous oxide.     

Problems and aspects of cooperation between pedagogs, youth health professionals and pediatric neuropsychiatrists in rehabilitation of behavior and achievement disorders in children with normal intelligence]

In those cases where the subjects involved tend to show pathological psychophysical reactions, it is necessary for a cooperative effort to be made by pedagogs, psychologists, and medical experts (pediatricians and pedoneuropsychiatrists). This may be realized by patient-related corrdinative consultations or psychotherapeutic treatment and subsequent individual pedagogic promotion and encouragement depending upon the degree of manifestation and generalization of the disorders. The use of various methods (modified but predominantly pedagogic and directive approaches and chiefly psychological and nondirective methods of treatment, respectively) involve different responsibilities of experts for the process of rehabilitation (in regard to both time and content). Also, the authors show that this is not in contradiction to general objectives of education and training and that every effort is made to reconcile medical and psychological objects with pedagogic requirements.     

The EEG in subacute sclerosing panencephalitis (SSPE)]

This article gives an overview of electroencephalographic results obtained in the case of subacute sclerosing panencephalitis. Severe disturbances of background activity have been observed in all patients. Repetitive complexes usually occur transitorily, so that they cannot always be detected in individual cases. Repetitive complexes must be regarded as being typical of the disease, and consideration must be given in this connection to their particular characteristics (repetition frequency, constancy of form, relations to disorders characterized by myoclonus) and the clinical picture.
