Is electrodermal testing as effective as skin prick tests for diagnosing allergies? A double blind, randomised block design study.

OBJECTIVE: To evaluate whether electrodermal testing for environmental allergies can distinguish between volunteers who had previously reacted positively on skin prick tests for allergy to house dust mite or cat dander and volunteers who had reacted negatively to both allergens. DESIGN: Double blind, randomised block design. SETTING: A general practice in southern England. PARTICIPANTS: 15 volunteers who had a positive result and 15 volunteers who had a negative result on a previous skin prick test for allergy to house dust mite or cat dander. INTERVENTION: Each participant was tested with 6 items by each of 3 operators of the Vegatest electrodermal testing device in 3 separate sessions (a total of 54 tests per participant). For each participant the 54 items comprised 18 samples each of house dust mite, cat dander, and distilled water, though these were randomly allocated among the operators in each session. A research nurse sat with the participant and operator in all sessions to ensure blinding and adherence to the protocol and to record the outcome of each test. OUTCOME: The presence or absence of an allergy according to the standard protocol for electrodermal testing. RESULTS: All the non-atopic participants completed all 3 testing sessions (810 individual tests); 774 (95.5%) of the individual tests conducted on the atopic participants complied with the testing protocol. The results of the electrodermal tests did not correlate with those of the skin prick tests. Electrodermal testing could not distinguish between atopic and non-atopic participants. No operator of the Vegatest device was better than any other, and no single participant's atopic status was consistently correctly diagnosed. CONCLUSION: Electrodermal testing cannot be used to diagnose environmental allergies.

Food sensitivity, a search for underlying causes. Case study of 12 patients.

Twelve cases of multiple food sensitivity were studied. All had responded to food elimination and a number were receiving sublingual food desensitization drops. An underlying cause was postulated and looked for. The method used was an electrical recording technique called the segmental electrogram. All of the cases were seen to have a primary colonic dysfunction which has been described as Dysbiosis. It was assumed that the colonic dysfunction was due to abnormal intestinal flora and this was corrected by a repopulation of the bowel with normal commensals and the simultaneous stimulation of liver and pancreatic function. This resulted in all of the patients losing at least a number of their sensitivities and those who were on sublingual desensitization drops were able to stop these drops and tolerate the foods without any further problem. It has postulated that much of multiple food and chemical sensitivity is due to underlying causes of which Dysbiosis is one.

Physiological and psychological explanations for the mechanism of acupuncture as a treatment for chronic pain.

Many suggestions have been made about the possible mechanism of acupuncture as an analgesic therapy. This review provides a comprehensive account of the neurological, neurohumoral and psychologically-based hypotheses put forward. Although the exact mechanism of this treatment remains unclear, it is apparent that reproducible neurological and chemical changes occur in response to acupuncture, and that these changes almost certainly modify the response to, and perception, of pain. The mechanism of chronic pain is completely understood, but within this framework we understand acupuncture as completely as most other types of analgesic treatment.

Randomised double-blind trial on the immediate effects of naloxone on classical Chinese acupuncture therapy for chronic pain.

The present study was designed to test the hypothesis that acupuncture therapy and acupuncture analgesia are both endorphin mediated. Thirty consecutive patients, all with pain at the time of treatment, were chosen. Classical acupuncture was used on seventeen patients; ear acupuncture was combined with classical Chinese acupuncture on eight patients, and ear acupuncture alone was used in five cases. No electrical stimulation of any sort was used. Pain was assessed by the patients on a visual scale of 0 to 100 before and after acupuncture therapy. Immediately following the post-acupuncture pain assessment, the patient was injected intravenously with a 1 ml. injection of 400 micrograms of Naloxone or a 1 ml. injection of 0.9% Sodium Chloride on a randomised double-blind basis. The effect on pain relief was noted immediately and after thirty minutes. No significant change in pain relief already obtained was noted after Naloxone in any patient. This does not support the hypothesis that acupuncture therapy is mediated by endorphin.
