OBJECTIVE Current criteria for performing relaparotomy for suspected peritonitis are non explicit and based on non-quantitative, subjective arguments or hospital practice. The aim of this study was to determine the value of routinely used clinical and diagnostic parameters in early detection of postoperative, diffuse peritonitis (PP). Furthermore, the(More)
A total of 28 patients with a hemifacial spasm were examined using transcranial magnetic stimulation. The potentials were evoked cortically and cisternally; latencies and amplitudes of each potential were measured in the levator labii muscle and in the orbicularis oculi muscle. After cortical stimulation, differences in latencies were found between the(More)
Thirty-five patients with essential blepharospasm were investigated electrophysiologically after local treatment with subcutaneous periocular injections of botulinum toxin. In all patients the blink reflex was measured on both sides. The results showed in some cases reproducible changes in the reflexes, indicating a central supranuclear origin for the(More)
We present a combined electrophysiological diagnostic procedure for patients with facial hyperkinesia. With the new method of magnetic stimulation a central cortical stimulation is possible to represent the total way of the facial nerve. The combination of magnetic stimulation with other methods such as the blink reflex may lead to topodiagnostic statements(More)
Following a general description of pathophysiological changes of an injured peripheral nerve, a survey is presented in which those electrodiagnostic tests that are of practical relevance today in cases of facial and recurrent nerve pareses, are defined and the methods used are described (electromyography, neuromyography, blink reflex, reflex myography of(More)
