Nongaussian distribution curve of heterophorias among children.

The purpose of this study was to measure the distribution curve of horizontal and vertical phorias among children. Kolmogorov-Smirnov goodness of fit tests showed that these distribution curves were not Gaussian among (N = 2048) 6- to 13-year-old children. The distribution curve of horizontal phoria at far and of vertical phorias at far and at near were leptokurtic; the distribution curve of horizontal phoria at near was platykurtic. No variation of the distribution curve of heterophorias with age was observed. Comparisons of any individual findings with the general distribution curve should take the nonGaussian distribution curve of heterophorias into account.

Reliability and validity of the dot visual acuity test.

The reliability of the dot visual acuity test (DVAT) was demonstrated using the test-retest method. The test, however, was not found to be valid when comparing it with the Sjögren test. Since the DVAT has previously been shown to be valid when compared to the Tumble E test, these results bring into question the validity of the Sjögren test when compared to the Tumble E test.

[Recurrent infarction without coronary atheromatosis].

Acute myocardial infarction without obstructive atherosclerosis is a well known entity characterized by the young age of the patients, the low incidence of risk factors and the absence of pre- and post infarction angina. The myocardial necrosis is probably caused by a thrombotic phenomenon perhaps initiated and/or exacerbated by a coronary spasm. It is generally thought that recurrence is rare and long term prognosis relatively benign but this may be a misconception. Three cases are reported of patients who had a second myocardial infarction, transmural infarction in each case, 17 to 36 months after the initial event. Prophylactic treatment after the second accident seems undoubtedly indicated. Until large randomized trials have established the best treatment, it appears logical to prescribe antithrombotic drugs (antiplatelet or anticoagulant drugs) with, perhaps, coronary spasmolytic drugs like calcium antagonists.
