[Contact thermography in breast pathology. A critical review].

The paper reports the Authors' experience in over 12,000 patients affected by manifest or presumed breast pathologies examined using contact thermography and assess the number of correct responses. This technique proved reliable in patients aged under 30 with benign pathologies or palpable nodules. On the other hand, it was not reliable in the case of pathologies with negative objectivity, and therefore in the context of screening programmes for the early diagnosis of tumours.

[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.

[Infrared tympanic thermography. A comparison of body temperature measured rectally and from the tympanic membrane].

Infrared tympanic thermography is a new method of measuring body temperature. We compared body temperature measured in the rectum and in the ear in 25 patients. The results reveal a difference of average +/- 0.3 degree C. We also measured the time used to perform the above procedures. We found that the preparation and completion procedures took on average two minutes and 50 seconds when the body temperature was measured in the rectum. Taking the temperature in the ear took on average 42 seconds. We found that this new method was an accurate and quick method to measure body temperature.

[Possibilities of contact chromatic thermography in the diagnosis of lung cancer].

Thermographic results were analyzed in 40 lung cancer patients and in 2 patients with acute pneumonia. The diagnosis and spreading of disease were established during x-ray, bronchological and morphological investigations. Normal temperature distribution was observed on the skin surface of lung cancer patients. The appearance of local hyperthermia did not depend on a stage of lung cancer. The sensitivity of chromo-thermography in establishing lung changes in tumors was 80% but thermosemiotics was not specific for cancer only. Similar thermosemiotics was noted in acute pneumonia. Comparative assessment of temperature distribution on the chest surface and perfusion scintigraphy in 24 patients made it possible to give correct interpretation of various temperature drop values in hyperthermia.

[Thermography in the diagnosis of vascular neuritis of the optic nerve].

A new method for diagnosing vascular neuritis of optic nerve by means of thermography is proposed. Among 47 patients with diagnosis of optic nerve neuritis of unclear etiology, in 37 of them vascular genesis of the disease was diagnosed. The thermograms have shown appearance of dark "cold" spots and a fall of temperature by 1.0 degrees C and lower in the supraorbital and orbital areas of the affected eye. The method is highly precise (90.27%, sensitive (94.9%) and doesn't require long time.

[Liquid-crystal thermography in the diagnosis and assessment of treatment efficacy in patients with chronic lymphedema of the lips].

Thermographic examination of 80 patients with chronic labial lymphedema (CLL) in various stages of the condition has revealed a clear-cut correlation between the process stage and thermal topography manifestations. This helped plan a differentiated approach to the choice of the treatment strategy in various CLL phases. Changed thermography data in the course of treatment evidence the possibility of applying this method to the assessment of the treatment efficacy in CLL.

Testicular temperatures measured by thermistor probe and contact thermography.

The results of this study indicate that contact scrotal thermography provides a means for detecting relative differences in temperatures within the testes, but absolute temperatures, as determined by thermistor probes, are about 5% lower. The data do not indicate that this difference is constant, and a simple correction factor cannot be used to equilibrate the two methods of determining the intratesticular temperature. The data also indicate that elevated intratesticular temperatures are associated with surgically induced varicoceles in monkeys.

Effects of the heat-tonification method on the surface temperature of the body observed by infra-red thermography.

With the infra-red thermography, 73 tests of the effect of Heat-Tonification maneuvers on body surface temperature were made. The experiments showed that application of Heat-Tonification produced marked elevation of temperature at the site of puncture, over the face and the front of the neck. The differences between pre- and post-needling temperatures were statistically significant (P less than 0.02 and P less than 0.01). Furthermore, 44.8% of the tests showed elevation of temperature over the trunk and extremities, and the distribution of temperature elevation followed the course of the meridians mostly. The findings demonstrated that the Heat-Tonification method mobilized Qi and activated Blood through influence over the vegetative nervous system that led to readjustment of blood circulation.

[Contact plate thermography with cold provocation tests for the diagnosis of Raynaud's phenomenon].

Since the contact plate thermography became a serious method to diagnose a vasospasm in form of Raynaud's phenomenon but absolute data for the behavior of the hand temperature under effects of cold were missing, 80 normal persons and 47 patients with a Raynaud's phenomenon were examined to determine the re-warming time after a defined cold exposition and to distinguish normal finger blood flow from pathological. To control the cold exposition of the hands, water immersions with three different temperatures and exposition times were used: 20 degrees C and 3 min., 15 degrees C and 2 min., 10 degrees C and 1 min. The measured re-warming time is the time, in that the thermographical color impression is the same as before the exposition to the cold. Patients with a Raynaud's phenomenon have a significant longer re-warming time than normal persons. The re-warming time of 70-80% of the group of normal persons is 10 min. for the 3 min./20 degrees C test, 15 min. for the 2 min./15 degrees C test and 25 min. for the 1 min./10 degrees C test. These times are a sign for normal behavior; times that lie above these are abnormal and make the diagnosis of a vasospasm reasonable. The diagnosis of a Raynaud's phenomenon is only possible with the typical clinical symptomatic.

Contact thermography for assessment of skin damage due to experimental irritants.

Irritant dermatitis after application of experimental irritants was studied by means of contact thermography. Sixteen healthy persons were patch-tested, using the following irritants: Sodium lauryl sulphate, benzalkonium chloride, nonanoic acid, hydrochloric acid, croton oil, sapo kalinus and sodium hydroxide. A main finding was that croton oil after 24 h caused a warm skin lesion, and sodium lauryl sulphate after 96 h caused a cold skin lesion. This study emphasizes the differences in the skin reactions to different irritants.

[Contact thermography in the differential diagnosis of benign tumors and cancer of the breast].

Contact thermography was performed in 87 patients with benign and in 75 with cancerous tumours of the breast. Hyperthermia over the tumour is characterized by a 2.2 degrees C and higher increase of the temperature and was registered only in cancer of the breast. Anisothermy of the breast was characterized by a +/- 0.5 degrees C and higher and may be considered as a supplementary diagnostic sign distinguishing cancer of the breast from benign tumours.

Liquid crystal thermography as a diagnostic aid and objective monitor for TMJ dysfunction and myogenic facial pain.

Liquid crystal contact thermography was used to assess both normal control patients and patients with temporomandibular joint and myofascial pain. The technique appears capable of detecting temperature changes around the TMJ and muscles of mastication. Patients with painful internal derangements of the TMJ have warm areas over the joint, and those with myogenic facial pain symptoms have areas of variable temperature over the masseter muscle. After successful nonsurgical treatment of these conditions, the thermograms return to normal.

Treatment of acute superficial thrombosis and follow-up by computerized thermography.

Superficial vein thrombosis (SVT) is a common complication of varicose veins. Treatment may be surgical by removal of the superficial clots under local anesthetic or medical in association with elastic compression and mobilization. In this study 83 patients with SVT were randomised in treatments groups: A--superficial thrombectomy and elastic compression (EC); B--Ca Heparin (0.5 mgs b.i.b.) + EC; C--Venoruton (1 g, t.i.d.) + EC; D--Venoruton (1 g, t.i.d.) after superficial thrombectomy + EC; E--elastic compression. All treatments were applied for 8 weeks. The evolution of SVT was studied by a system, based on thermography, which analyse by a computerized system the variation of the hyperthermic areas (HA) on thermograms. This was associated with subjective and objective clinical evaluation. Results indicate a decrease of HA in all groups but patients treated with superficial thrombectomy show a significantly (p, 0.05) greater and faster reduction of HA. The reduction of HA produced by Venoruton was also significantly greater (p less than 0.05) than that observed in patients treated by Ca Heparin or elastic compression and it determined also a faster and greater (p less than 0.05) decrease of HA after thrombectomy. These results were confirmed by clinical observations. In conclusion results from this study indicate a positive effect of Venoruton in SVT in determining a faster decrease of hyperthermic areas probably by decreasing local inflammation.
