We describe a case of hemitrophy in a 12-year-old child presenting with seizures, hemiplegia and mental retardation. Hemiatrophy of one cerebral hemisphere is not frequently encountered in clinical practice. When this develops early in life (during the first two years), certain cranial changes like ipsilateral hypertrophy of the skull and sinuses occur. Asymmetry of cerebral hemispheric growth ...

The Dutch storm surge barrier’s failure rates are designed and certified to fail maximally once every ten thousand years. Recent audits question this failure rate. Software is mentioned as a major cause and quantifying it and its reliability turned out to be a problem. We show how to quantify and assess the software and its failure rates using minimal data. The results are applicable to other d...

In this laboratory we have previously employed, as a preliminary step in the isolation of oxytocin and vasopressin from posterior pituitary glands (l-3), the method introduced by Kamm et al. (4) for obtaining a fraction high in oxytocic activity and another high in pressor activity. Further purification involved the use of countercurrent distribution (l-3) and zone electrophoresis (3). We have ...

Dyke Davidoff Masson syndrome (DDMS) refers to atrophy or hypoplasia of one cerebral hemisphere following a prior fetal or childhood insult. It has characteristics of clinical and radiological changes. These changes include hemiparesis, seizures, facial-asymmetry, and mental retardation. We present a 25-year-old man with crossed cerebrocerebellar atrophy and DDMS. His seizures were well control...
