[An old remedy newly evaluated: the cervical syndrome].

Among the group of more than 5,000 patients reported here and suffering from headaches the cause of these headaches was to be found in 39.5% of the cases in the cervical spine. Two thirds of these revealed a malpositioning of two vertebrae against each other while the remaining third showed narrowing of the intervertebral foramina. Other cervical pathology comprises less than 6% of a total of more than 17,000 patients diagnosed as having a cervical syndrome. In the first group manual repositioning of the cervical spine brought about 82% of complete normalization of the position of the cervical spine (with concomitant total loss of symptoms) while of the remaining 18% half turned out to be free of symptoms as well. In case of narrowing of i.v. foramina electric blocking of the respective nerves using a very special type of current also lead to loss of symptoms in between 80 and 90% of these cases. Diagnostic aids and special techniques are presented. Thus in cervical causation of headaches clear diagnosis leads to proper and very effective therapy (without drugs). It should be thought of more frequently for the benefit of patients.

[Responsible prescription of hearing aids].

A case report serves to document that sufficient cerebral circulation is mandatory for sustaining function of the brain. If impulses from the ear are not processed within the areas of the brain normally doing this, prescription of a hearing aid will not improve the capacity to perceive in a patient being hard of hearing. In these cases, one should rather examine the state of the cerebral circulation.

Transdermal transcutaneous electric nerve stimulation for pain: the search for an optimal waveform.

A search has been made for an optimal wave form for transcutaneous nerve stimulation for pain. The effect of electrical stimulation of sympathetic nerves was studied as a model because (1) this system has small diameter axons, as do nociceptive fibers, and (2) alteration of activity in sympathetic fibers may be evaluated objectively by observing the effects upon circulation. A transcutaneously applied waveform was found which influenced circulation maximally, suggesting that sympathetic nerves were affected by the transdermal stimulation. The hypothesis that these stimulation parameters might be optimal for pain relief was tested. Relief of 40% or more was obtained in 68% of 2,800 patients suffering from chronic pain of diverse origin, utilizing this waveform.

[Electric blockade of sympathic and somatic nerves through the skin (author's transl)].

A model was conceived and tested which enabled the investigation of the objective effect of transcutaneous nerve stimulation using various kinds of stimuli. The most effective stimulus was then used in an investigation of clinical conditions where sympathetic blockade may be helpful. It was seem to be quite effective. In the wake of these good results the same type of stimulus was used to influence other thin fibre nerves which conduct pain. After grading 2800 cases of chronic pain according to the scale of Picaza-Shealy-Ray electrostimulation decreased pain in 59% of cases overall or in 61% and 35% of cases of benign or malignant origin, respectively. These results seen on a long-term control basis are generally obtainable and reproducible if the criteria put forward in this paper are followed rigidly.

[The treatment of intractable pain by transdermal electrostimulation (author's transl)].

Various kinds of electric currents were examined with regard to their efficacy in the relief of pain when applied transdermally. The most suitable form of current was applied to 39 cases (who had been especially selected in a negative sense) suffering from intractable pain. About half were patients with malignant disease encroaching or causing pressure on nerves or plexuses. The other half consisted of patients suffering from intractable neuralgia totally resistant to all forms of therapy. A diagram of the pulsating direct current is shown. Results were as follows: no effect in nine cases; 5 cases obtained moderate relief of pain for up to 12 hours; the remaining 25 patients reported complete relief of pain already after the first application of current lasting from 12 hours to 3 weeks and--after a series of sessions (3 to 17 treatments)--of up to 12 months. Two of these patients were supplied with a unit for home treatment after their relatives had been trained in the use of the instrument. In these two cases, however, a large number of treatment sessions became necessary. These results warrant continued study of cases of this kind and call for a study of the basic mechanisms possibly underlying these effects. If the present results are confirmed, it is planned to introduce battery-powered miniaturized sets, which patients may use themselves after fixation of electrodes.

[Assessment and treatment of intractable pain: six months' experience in the relief of pain at the ludwig Boltzmann Institute of Clinical Oncology (author's transl)].

A preliminary report is presented on the results achieved in the assessment and treatment of patients with intractable pain during the first six months experience gained following the appointment of a pain consultant at the Ludwig Boltzmann Institute of Clinical Oncology. Nerve blockade was carried out 106 times in 45 patients suffering from primary or secondary malignant disease and 71 times in 18 patients with other conditions; intrathecal instillation of 96% alcohol was performed once and 2 chordotomies were also performed. One patient needed antidepressive therapy. Major questions relating to this problem are discussed. Gratifyingly satisfactory results were observed in more than two thirds of the patients. These objective findings and the subjective impressions obtained from patients, their relatives and our personnel prompted us to continue with this type of treatment for pain and to increase our efforts in this direction.
