Four patients are presented who exhibited progressive muscular rigidity in both legs, the thoracolumbar, paraspinal and the abdominal muscles. In only one patient, there was an initial involvement of the shoulder girdle muscles. Electromyography in all four patients at rest recorded continuous electric activity resembling an interference pattern. ⋯ All patients improved on clonazepam. Trials of intermittent high-dose methylprednisolone administration gave relief from rigidity in one patient and permitted reduction of clonazepam in another. Intravenous immunoglobulins however had no effect in one patient.

Randomized Controlled Trial Clinical Trial
[Amitriptyline in therapy of chronic tension headache].
In a double-blind, placebo-controlled trial, the effect of 75 mg of a slow-release formulation of amitriptyline on the clinical severity of chronic tension-type headache and on headache-associated neurophysiological parameters (EMG activity, exteroceptive suppression of temporal muscle activity, contingent negative variation (CNV) and experimental pain sensitivity) was investigated. All of the patients treated had a history of headaches of many years standing, and numerous failed attempts at treatment. In the amitriptyline group, a significant reduction in daily headache duration was already found in the third week of treatment, while in the placebo group no significant changes in headache duration were to be seen. ⋯ The sensitivity to suprathreshold experimental pain, however, was significantly reduced. The data show a statistically relevant reduction of daily headache duration in chronic tension-type headache. However, they also show that amitriptyline can only partly alleviate chronic headaches but cannot cure them.

The cognitions of 20 emergency-physicians while working on a mobile resuscitation unit were examined by means of questionnaire in over 260 situations of resuscitation. A pattern of cognitions could be detected: Emergency physicians appear not to think very much during resuscitation. If there are thoughts, these usually concern the obvious, or what is immediately present in the situation, i.e. the patient or the patient's relatives; repression may also play a role. ⋯ Distancing by means of cognition was ubiquitously employed as a coping strategy by physicians when in situations which were perceived as not having a positive outcome. Thoughts about "own death" or "about the patient" are specific, however, for certain groups of doctors. Results of the present investigation suggest that physicians have cognitions about relatives during the process of decision making, and cognitions about the patient during the resuscitation manoeuvre.

Recently, the ischemia-test (IT) had been suggested to be part of the diagnostic procedure for reflex sympathetic dystrophy (RSD). The present study investigated, for the first time whether pain suppressing, as typically occurring under the IT, would correlate in RSD to the pain relieving effect following a diagnostic guanethidine blockade. ⋯ Thus, both procedures have the same diagnostic value for pain in RSD. These results are in agreement with new pathophysiological considerations, assuming an indirectly (via the microvascular system) mediated sympathetic-afferent coupling as a cause of pain in RSD.
