[Computerized digital thermometry in Raynaud's disease. Personal experience].

BACKGROUND: Computerized digital thermometry has been used for instrumental diagnosis of Raynaud's disease, that is characterized by diminution of the cutaneous temperature of the fingers and the late delayed recovery. Thermometry permits to measure basal temperature of the ten fingers, during cooling to 10 degrees C ("cold test") and the response, measuring temperature minute by minute up to 25 degrees. METHODS: In order to assess vasospastic ischemic disease a total of 66 subjects have been examined: 19 were asymptomatic for acrolocalised pathologies (control subjects) and 47 were symptomatic. RESULTS: No close correlation was observed between clinic and instrumental data. In fact 31.5% of the asymptomatic subjects had a "non-normal" reaction to the test; on the other hand, in the group of female over-50-years-old with symptoms suggesting Raynaud's disease, 38.5% of cases revealed "normal" instrumental patterns. Therefore no discriminating parameters were identified which might have allowed the instrumental identification of subjects suffering from Raynaud's disease compared to healthy individuals. CONCLUSIONS: In conclusion, computerised digital thermometry is a technique with a good level of sensitivity, while the specificity is scarce.

Treatment of Raynaud's disease: evaluation of a behavioral approach.

Eight patients with Raynaud's disease were treated with a behavioral program which included skin temperature biofeedback, relaxation training and protocol individualization based on the investigators' psychological understanding of each patient. Three patients improved clinically, although only one learned self-control of skin temperature. Anxiety reduction, brought about by relaxation or changes in the program to suit individual needs, appeared to be an important aspect of the treatment program.

[The circulatory status in the extremities in Raynaud's disease and syndrome].

In 39 patients with the disease and syndrome of Raynaud the state of the upper extremities blood circulation was studied up. The reliable lowering of indexes of the disease in III-IV stage in comparison with the normal level is noted. The most informative methods are rheoplethysmography and Doppler investigation of the main arteries of extremity.

[Functional diagnosis by directional doppler-ultrasound in patients with Raynaud's disease (author's transl)].

7 patients with primary and 3 patients with secondary Raynaud's disease were studied by directional Doppler-ultrasound. Flow curves were registered of radial and ulnar artery in rest and during reactive hyperemia following ischemia and muscle work before and under medical treatment. Flow at rest and after provocation was much less than in normal persons. Effect of treatment could be demonstrated, so that this method seems to be very helpful in followup studies of patients with Raynaud's disease.

Biofeedback, autogenic training, and progressive relaxation in the treatment of Raynaud's disease: a comparative study.

Twenty-one female patients suffering from diagnosed idiopathic Raynaud's Disease were trained to raise digital skin temperature using either autogenic training, progressive muscle relaxation, or a combination of autogenic training and skin temperature feedback. Patients were instructed in the treatment procedures in three one-hour group sessions spaced one week apart. All patients were instructed to practice what they had learned twice a day at home. Patients kept records of the frequency of vasospastic attacks occurring over a four-week baseline period, and during the first four weeks and the ninth week of training. In addition, patients underwent four laboratory cold stress tests during which they were instructed to maintain digital temperature as the ambient temperature was slowly dropped from 26 degrees to 17 degrees C. Cold stress tests were given during week 1 of baseline and during weeks 1, 3, and 5 of training. No significant differences between the three behavioral treatment procedures were obtained. In addition, the ability of patients to maintain digital temperature during the cold stress challenge showed significant improvement from the first to the last tests. Symptomatic improvement was maintained by all patients nine weeks after the start of training. The implications of these findings for the behavioral treatment of Raynaud's Disease are discussed.
