Journal ArticleDOI
Prediction of poor outcome within the first 3 days of postanoxic coma
E.G.J. Zandbergen,A. Hijdra,Johannes H. T. M. Koelman,A. A.M. Hart,P. E. Vos,Marcel M. Verbeek,R.J. de Haan +6 more
TL;DR: Poor outcome in postanoxic coma can be reliably predicted with somatosensory evoked potentials and neuron-specific enolase as early as 24 hours after cardiopulmonary resuscitation in a substantial number of patients.
Journal ArticleDOI
Systematic review of early prediction of poor outcome in anoxic-ischaemic coma.
E.G.J. Zandbergen,Rob J. de Haan,Christiaan P Stoutenbeek,Johannes H. T. M. Koelman,A. Hijdra +4 more
TL;DR: Because evoked potentials are also the least susceptible to metabolic changes and drugs, recording of SSEP is the most useful method to predict poor outcome.
Journal ArticleDOI
Prognosis of coma after therapeutic hypothermia: a prospective cohort study.
Aline Bouwes,Jan M. Binnekade,Michael A. Kuiper,Frank H. Bosch,Durk F. Zandstra,Arnoud C. Toornvliet,Hazra S. Biemond,Bas M. Kors,Johannes H. T. M. Koelman,Marcel M. Verbeek,Henry C. Weinstein,A. Hijdra,Janneke Horn +12 more
TL;DR: This study was designed to establish the reliability of neurologic examination, neuron‐specific enolase (NSE), and median nerve somatosensory‐evoked potentials (SEPs) to predict poor outcome in patients treated with mild hypothermia after cardiopulmonary resuscitation (CPR).
Journal ArticleDOI
A meta-analysis of P50 studies in patients with schizophrenia and relatives: Differences in methodology between research groups
TL;DR: Whether patients with schizophrenia as well as their relatives show deficits in sensory gating reflected by an abnormal P50 ratio and to quantify the differences from controls is determined and P50 suppression would not qualify as an endophenotype for schizophrenia.
Journal ArticleDOI
Progression of abnormalities in adrenomyeloneuropathy and neurologically asymptomatic X-linked adrenoleukodystrophy despite treatment with “Lorenzo’s oil”
B. van Geel,J. Assies,E.B. Haverkort,Johannes H. T. M. Koelman,B.W.J.M. Verbeeten,R. J. A. Wanders,Peter G. Barth +6 more
TL;DR: It is advocated that “Lorenzo’s oil” should not be prescribed routinely to patients with X-ALD who already have neurological deficits, and side effects were often noted—namely, mild increases in liver enzymes, thrombocytopenia, gastrointestinal complaints, and gingivitis.
