A patient who developed a synergistic bacterial gangrene caused by a group A beta-haemolytic streptococcus and a Staphylococcus aureus is described.
Five cases are presented showing on the EEG pseudo-rhythmic discharges appearing on almost flat lines, after reanimation of a cardiac arrest. The morphology of the complexes is quite similar, except in the period immediately preceding death, where they are more disformed. All patients died within the following days, except one. In four of the five cases myoclonic jerks occurred, consisting of brief convulsions over the whole body, especially in the arms and the face. A literature survey shows that this EEG pattern after circulatory arrest, is not rare. It is almost always followed by death. Myoclonic jerks may or may not be present and are not necessarily synchronous with the EEG discharges. The electrogenetic origin is not yet elucidated, although it seems that the pattern may appear at a state of complete loss of cortical function.

This paper presents a summary of 106 patients monitored at the Sleep/Wake Disorders Center of the University Hospital in Antwerp. Diagnostic assessment is based upon information from history, physical and psychiatric examination, sleep logs, psychological tests and polysomnographic workups, including at least 2 consecutive nights. A major conclusion is that complete understanding of sleep problems needs a multifactorial approach. This not only leads to a more accurate description of the disorder, but also to rational, specific and individualized treatment strategies.
