Disease relevance of Thermography

• We studied 20 normal subjects, 22 patients with carpal tunnel syndrome, and 15 with ulnar neuropathy at the elbow to compare the diagnostic accuracy of infrared thermography with that of conventional electrodiagnostic studies [1].
• The purpose of the present study was (1). to measure the temporal and spatial profiles of neurogenic inflammation and hyperalgesia induced by capsaicin by using thermography/laser-Doppler flowmetry and various sensory tests, and (2). to correlate the parameters related to neurogenic inflammation with the areas of secondary hyperalgesia [2].
• After spray application to the forearms of volunteers, without massage, the erythema produced was measured by thermography and correlated with the concentration of 2 salicylate components of the mixture found in local and systemic venous blood [3].
• The head temperature of 127 patients (double-blind), 102 migraines (52 during headache attack and 50 headache-free) and 25 healthy control subjects were evaluated using thermography in basal condition and 30, 60, 90, and 120 min after s.c. sumatriptan injection of placebo [4].
• Tamoxifen responders selection by computerized contact thermography in benign breast disease [5].

High impact information on Thermography

• Discussed in this article are six of these cases, two involving Laetrile (amygdalin), two involving immunoaugmentative therapy, and two involving thermography, technologies that had previously been assessed as not safe, not effective, or inadequately evaluated [6].
• Infrared video thermography was used to observe ice nucleation temperatures, patterns of ice formation, and freezing rates in nonacclimated and cold acclimated leaves of a spring (cv Quest) and a winter (cv Express) canola (Brassica napus) [7].
• Liquid crystal thermography: quantitative studies of abnormalities in carpal tunnel syndrome [8].
• Late-phase reactions to histamine were less intense and could only be detected with thermography; only thermographic units showed a decrease (26%) in response to azelastine [9].
• Intracoronary temperature was measured with a thermography catheter developed in our Institution: a thermistor probe with a temperature accuracy of 0.05 degrees C, was attached at the distal end of a long 3F polyurethane shaft [10].

Chemical compound and disease context of Thermography

• Technetium-labelled compounds and thermography for non-invasive detection of deep vein thrombosis [11].
• Usefulness of finger thermography to assess cyclosporine toxicity after heart transplantation [12].

Biological context of Thermography

• Identification of functioning sweat pores and visualization of skin temperature patterns in X-linked hypohidrotic ectodermal dysplasia by whole body thermography [13].
• The warmest interscapular skin areas were located by thermography in six healthy subjects during ephedrine-induced thermogenesis [14].
• Vasodilatation was recorded by contactless infrared emission thermography, and plasma protein exudation was measured by the Evans Blue leakage technique and by measurement of the paw volume in anaesthetized rats [15].
• Acupuncture and tele-electronic infra-red thermography [16].
• Information obtained from the literature, responses to a Federal Register notice of this assessment, PHS agencies and medical specialty groups failed to support claims of efficacy of thermography as a useful diagnostic modality for non-breast indications [17].

Anatomical context of Thermography

• Dilatation of subcutaneous perforating blood vessels associated with capsaicin-induced cutaneous axon reflex: demonstration with subtraction thermography [18].
• Sympathetic blockade after stellate ganglion block with bupivacaine was assessed by liquid crystal thermography [19].
• A study was conducted to determine changes in serum LH and testosterone concentrations and in scrotal surface temperature (SST; measured with infrared thermography) following GnRH treatment and to predict the number of spermatozoa collected and the proportion that were viable [20].
• Dynamic thermography of the knee joints in rheumatoid arthritis (RA) in the course of the first therapy of the patient with methylprednisolone [21].

Associations of Thermography with chemical compounds

• Prostaglandin E1 vasospastic disease and thermography [22].
• Temperature of the fingers and hands recorded by thermography did not change significantly with saline infusions, but did rise during PGE1 infusions (mean rise 2.0 degrees C at 48 hours, p less than 0.001), and was maintained when measured again 2 weeks later (mean rise 1.56 degrees C, p less 0.001) [23].
• Due to considerable spontaneous variability and change in temperature already after instillation of diluent, thermography was not sensitive enough to identify positive CPT results [24].
• The axon reflex induced by intracutaneous application of capsaicin to the forearm of human subjects and the back of anesthetized rats pretreated with intravenous injection of Evans blue was investigated using sequential subtraction thermography [18].
• Application of the first patch was followed immediately by repeat eight-hour thermography, with hourly measurements of E2 and luteinizing hormone (LH) [25].

Gene context of Thermography

• Our results indicate the analgesic property of SST14 and demonstrate its capacity to reduce progressively joint inflammation confirmed by thermography and by reduction of pain, after a month of therapy [26].
• This indicates that not all patients had sufficient antiinflammatory medication with the final 6 mg/d of methylprednisolone as measured by dynamic thermography but not by ESR or CRP [21].
• These findings indicate that the sensitivity of LCT in CTS is low compared with NCS, and previous favorable reports concerning thermography in CTS may have been due to lack of control series or absence of quantitation [8].
• Thermographic analysis, performed using the AGA 782 Digital Thermography system, showed increasing temperature with increasing radiant exposure, with a maximum temperature of 47.2 degrees C at 55 mJ/mm2 [27].
• Arteriovenous communications in varicose veins localized by thermography and identified by operative microscopy [28].

Analytical, diagnostic and therapeutic context of Thermography

• Facial thermography during nasal provocation tests with histamine and allergen [29].
• In contrast, assessment of flare response and sympathetic reflexes using infrared thermography and photoplethysmography did not add further information for the diagnosis of CTS [30].
• Laboratory studies including uric acid and sedimentation rate were performed, as was a detailed physical examination and lumbar thermography [31].
• Application of thermography to the evaluation of the histamine skin test in man [32].
