Vision and academic performance of learning disabled children

The purpose of this study was to assess difference in academic performance among myopic, hyperopic, and emmetropic children who were learning disabled. More specifically, myopic children were expected to perform better on mathematical and spatial tasks than would hyperopic ones and that hyperopic and emmetropic children would perform better on verbal measures than would myopic ones. For 439 learning disabled students visual anomalies were determined via a Generated Retinal Reflex Image Screening System. Test data were obtained from school files. Partial support for the hypothesis was obtained. Myopic learning disabled children outperformed hyperopic and emmetropic children on the Key Math test. Myopic children scored better than hyperopic children on the WRAT Reading subtest and on the Durrell Analysis of Reading Difficulty Oral Reading Comprehension, Oral Rate, Flashword, and Spelling subtests, and on the Key Math Measurement and Total Scores. Severity of refractive error significantly affected the Wechsler Intelligence Scale for Children--Revised Full Scale, Performance Scale, Verbal Scale, and Digit Span scores but did not affect any academic test scores. Several other findings were also reported. Those with nonametropic problems scored higher than those without problems on the Key Math Time subtest. Implications supportive of the theories of Benbow and Benbow and Geschwind and Behan were stated.     

Hypertonic central nervous system complications from the viewpoint of the pathologist

Based on 2130 autopsies with a hypertension it is reported on the hypertensive CNS-lesions. The frequency of encephalomalacia was 12%. By 9.7% was founded brain haemorrhages. The relapse rate of haemorrhages was about 5%. The encephalomalacia existed by way of secondary finding in 24.7%, and the haemorrhage in 2.2%. The investigations showed an important arteriosclerosis by 39.8% in haemorrhages and by 51.6% in brain infarct. It was remarkable by the hypertensive brain haemorrhages a dominant right hemisphere.     

Ulnar sulcus syndrome--a contribution to course and prognosis

Of 1028 patients with 1138 peripheral nerve lesions, 142 suffered from an electrophysiologically proven SUS. At follow-up, 93 patients could be restudied. Spontaneous regressions were observed in patients below the age of 40 years and in case of a history under 6 months. So-called late pareses receded in no case without operative displacement of the ulnar nerve. However, if the etiology is unknown, the present results of investigation require reserve towards operative therapy.     

Aspects of process diagnosis in the psychotherapy of psychosomatic diseases

15 patients with psychosomatic diseases and the phenomenon of alexithymia, together with neurotic patients are treated psychotherapeutically in half-open groups. Contrary to the neurotics the patients show some special features regarding the process diagnostics. In assessing the wished and really experienced nearness to the group members there is a deficient ability to differentiate. During the therapeutic process the intrapsychic tension (EMI - Inventory of Emotionalities) is subject to great fluctuations or doesn't change. The occurrence of fluctuations in the EMI and of greater differentiations in the N-D-Test (Nearness-Distance-Test) suggest a good prognosis. A therapy of psychosomatic patients together with neurotic patients seems to be more effective than the treatment in homogeneous groups.     

Behavior of visual evoked potentials (pattern reversal VECP) in smokers

Twenty six clinically healthy smokers were studied with transient pattern visual-evoked potentials. In comparison with a sample of "normal" subjects we found a difference of some parameters (P less than 0.05): the P2-latency and the interocular difference of latency on average were 6-7 ms respectively 2 ms larger. Thirteen subjects have had a prolonged P2-latency (P less than 0.05) and/or a difference in interocular latencies larger than 5 ms. These findings may suggest on subclinical disturbances of visual system and indicators of an special sensitivity of that person. The findings are possibly related to tobacco-alcohol amblyopia.
