[Hemodynamic response of the digital artery to heat and cold in normal subjects, in systemic scleroderma and in Raynaud's disease].

Measurement of digital systolic pressure under hot and cold conditions provides objective data (in mm Hg) of the humero-digital gradient and of spasm induced by cold. Normal values are: digital systolic pressure at 30 degrees C: 94 +/- 12% of humeral systolic pressure; at 15 degrees C: 94.46 +/- 9.32%, and at 10 degrees C: 93.6 +/- 12% of digital systolic pressure at 30 degrees C. The significance of these two parameters resides in the fact that the humero-digital gradient is of etiological value in organic arterial disease, the specificity of the test being 94.4% in allowing distinction between Raynaud's disease and systemic sclerosis. The cold-induced spasm can provide quantitative evaluation of a clinical Raynaud's phenomenon with which it is correlated (specificity: 96%).

Comparison of behavioral treatments for Raynaud's disease.

Induced vasodilation by classical conditioning was compared to biofeedback therapy as treatment for idiopathic Raynaud's disease. Classical conditioning therapy consisted of 54 10-min immersions of both hands in water (43 degrees C) simultaneously with whole-body exposure to cold air (0 degrees C), given three times per day, 3 days per week, for 6 weeks. Biofeedback therapy consisted of eight sessions of electromyograph feedback (frontalis) while listening to relaxation tapes, followed by 10 sessions of digital thermal feedback while listening to relaxation tapes. Both groups received 10-min cold stress tests of whole-body exposure to 0 degrees C before and after treatments. Results indicated that both therapies significantly increased the digital temperature response to cold. Although no differences between classical conditioning and biofeedback were found at the end of training, a 1-year follow-up indicated that classical conditioning was more effective.

Manometric assessment of oesophageal involvement in progressive systemic sclerosis, morphoea and Raynaud's disease.

Oesophageal function was studied by radiography and manometry in fifty-one patients with progressive system sclerosis (PSS), fourteen patients with morphoea, twelve patients with Raynaud's disease and twenty-one normal subjects. Upper oesophageal sphincter pressure was not affected. Peristaltic contractions of the upper third of the oesophagus were significantly decreased in PSS and morphoea, but the lower two-thirds were affected only in PSS. Lower oesophageal sphincter pressure was significantly decreased in PSS but was normal in morphoea and Raynaud's disease. There was a significant correlation between oesophageal dysfunction and the duration of PSS. Manometry was better than radiography at detecting motor abnormalities, with a positivity of 86% compared with 66% for radiography. Oesophageal manometry should be employed routinely in the investigation of patients with suspected PSS or morphoea.

Behavioral treatment of Raynaud's disease.

In order to assess the efficacy of a behavioral intervention in the treatment of idiopathic Raynaud's disease, 30 female patients were trained to control their digital skin temperature using autogenic training or a combination of autogenic training and skin temperature feedback either in the laboratory or at home. All trained subjects demonstrated a significant ability to maintain digital skin temperature in the presence of a cold stress challenge and reported significant reductions in both frequency and intensity of vasospastic attacks. The addition of skin temperature feedback to autogenic training did not provide additional clinical benefit.

[Raynaud's disease and syndrome. Presentation of clinical experience].

The Authors report their experience concerning 256 cases of Raynaud's Disease and Syndrome observed from 1968 to 1987; 23 patients underwent surgery for the treatment of dystrophic or gangrenous lesions of the extremities (12 cervico-thoracic and 8 lumbar sympathectomies, 1 popliteal aneurysmectomy, 2 scalenotomies): a significant improvement of the clinical picture was observed in 91.30% of the patients who underwent the operation. The pharmacologic treatment obtained satisfactory results in 51.26% of all the patients. The Authors propose a three stage classification of raynaudian symptoms: I stage: sporadic vasoconstrictive crises; II stage: recurrent vasoconstrictive crises not invalidating working activity and "restitutio ad integrum" between attacks; III stage: recurrent and frequent crises invalidating working activity with asphyxia and/or ulcer-gangrene of the extremities. Both pharmacological and surgical treatment obtained the improvement of the clinical condition to an inferior stage in a high rate of patients. In three patients only (two of whom underwent scalenotomy and one popliteal aneurysmectomy) the complete and definitive cessation of raynaudian crises was observed.

[Thermography of collagen diseases with Raynaud's phenomenon].

In forty-four patients with collagen diseases accompanied with Raynaud's phenomenon(systemic lupus erythematosus(SLE)10, progressive systemic sclerosis(PSS)15, primary Sjögren's syndrome(PSJS)18 and mixed connective tissue disease(MCTD)1), we analyzed the thermography of fingers after thermal stimulation with cold water(15 degrees C, 30 seconds). In normal controls, the temperature of the distal points of fingers was higher and recovered more quickly than that of the proximal points(proximal interphalangeal joint; PIP). But in the patients with Raynaud's phenomenon, the temperature of distal point of fingers was lower and recovered more slowly than that of proximal points. Because the difference of the temperature between the distal and the proximal points (DP)is a good parameter to distinguish these two thermographic patterns, we analysed DP. DP is less influenced by room temperature than the temperature of fingers and the recovery temperature after thermal stimulation which have been used as indicators of Raynaud's phenomenon. DP in the normal controls was significantly higher than that in the patients. DP in PSS was lower than that in SLE and PSJS, and statistically associated with the markers of disease activities, such as erythrocyte sedimentation rate, titers of anti-RNP antibody and diffusing capacity of lung. These results show that thermographic pattern and the value of DP are the useful indicator of severity of Raynaud's phenomenon.

Skin temperature biofeedback for Raynaud's disease: a double-blind study.

The lack of control procedures inherent in most of the experiments conducted to assess the effectiveness of skin temperature biofeedback in the treatment of Raynaud's disease renders the results inconclusive. In this study, control groups and a double-blind approach are adopted. Thirty-six patients, carefully screened for a diagnosis of primary Raynaud's disease, were assigned to a skin temperature increase group (N = 12), to an EMG relaxation control group (N = 12), or to a notreatment control group (N = 12). All patients kept records of their symptoms for the duration of the study. Each subject in the two training groups received 20 sessions, the last 2 conducted under cold stress. data analysis according to original group assignment, as well as following regrouping of subjects according to several learning criteria, showed that while all patients reported a marked decrease in the number of vasospastic attacks, no significant differences were found among the three groups on the clinical measures used to assess symptomatic relief. The general improvement reported must therefore be attributed to nonspecific factors.
