Pathological visual field and brain tumor]

The general relationships between an operatively or autoptically localized tumor and the visual field determined by means of ikineticer perimetry are investigated, the patient stock being a total of 1756 neurosurgical brain-tumor inpatients. Examination of the visual field was possible with four fifths of the brain-tumor patients. Hemianopic, quadrantanopsic, or scotomatous defects of a topically localizable nature could be found in almost one third of the total patient stock available for examination. The clinically particularly interesting criteria of localization of homonymous-hemianopsia defects such as macular sparing and incongruence/congruence of visual field changes should be of no importance to the localization within the visual pathway of brain-tumor patients.     

Relations between pneumoencephalographic and electroencephalographic findings in childhood]

During simultaneous testing of electro-encephalograms and pneumoencephalograms in 200 children of various ages a proven correlation of statistics between both test procedures emerged as a well-defined parameter for evaluation. When making a statement about the correlation in findings between E.E.G. and P.E.G. the age of development in a child must be taken into consideration. Thus it emerged that in infants pronounced enlargement of the ventricular system correlates with active tension E.E.G. at increased inter-cranial pressure, while the coincidence of focal changes in E.E.G. and P.E.G. with advancing years becomes at first more pronounced after the tenth year of life (or puberty) but afterwards lessens.     

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.     

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.
