液晶热图诊断乳腺癌标准的探讨

经手术切除和病理检查证实有乳腺疾病者572例（其中,良性病变者396例、乳腺癌176例）的液晶热图△T和病理P型检查的结果发现：572例的△T均在2℃以下,其中良性组81.3%的病例在0.2℃以下,而乳腺癌组仅为4.5%;病理分期热图P型,78.4%的乳腺癌病例在4以下。故提出液晶热图诊断乳腺癌的原指标过高,应调整为△T0.2℃,P型4以上为宜。     

Optimising the methodology of calculating the cerebral blood flow of newborn infants from near infra-red spectrophotometry data

Cerebral blood flow can be measured in neonates by near infra-red spectrophotometry. The tracer is oxyhaemoglobin. The purpose of the study is to compare the test-retest variability of two previously proposed methods (UCH and COP) of analysis, and to investigate the influence of sampling rates, smoothing and integration periods. Under clinical conditions good measurements are often difficult to obtain. Therefore, a second goal is to find ways of determining the quality of individual measurements. 380 cerebral blood flow measurements from 69 infants are analysed. The data set is optimised statistically for the lowest test-retest variability and the following results are obtained. The test-retest variability of measurements at 2 s sampling time data is considerably worse than at 0·5 s sampling time. Smoothing does not change the test retest variability. A 6 s integration period gives higher values and higher test-retest variability than an 8 s integration period. By applying the suggested criteria, a test-retest variability of 17% is achieved, if 50% of the measurements are rejected. The mean cerebral blood flow is 12·2 ml(100 g)⁻¹ min⁻¹ for the UCH method and 97·7 ml(100 g)⁻¹ min⁻¹ for the COP method. The test-retest variability of both methods is comparable for 0·5 s sampling time. For 2 s sampling time the method proposed by Skov et al. is significantly better. These test retest variabilities represent maximum values, part of the observed variability may be due to physiological changes of unknown magnitude.     

Comparison between thermography and venous scintigraphy of the scrotum in the diagnosis of varicocele

Fifty-one consecutive infertile men were examined for the presence of (sub)clinical varicocele with both scrotal thermography and venous radionuclide scintigraphy. Venous scintigraphy with 99^mTC yielded false negative results in about half of the patients suspected of varicocele because of clinical findings and/or abnormal scrotal thermography. Venous scintigraphy cannot serve as an alternative for scrotal thermography for the detection of spermatic venous reflux in varicocele.     

Efficacy of low level laser therapy in myofascial pain syndrome: an algometric and thermographic evaluation

BACKGROUND AND OBJECTIVES: The efficacy of low level laser therapy (LLLT) in myofascial pain syndrome (MPS) seems controversial. Our aim was to clarify the effect of LLLT in MPS by using algometry and thermography. STUDY DESIGN/MATERIALS AND METHODS: Sixty-two patients with MPS having an active trigger point in the neck or upper back region were randomly divided into two equal groups according to therapy applied (group 1: LLLT + stretching exercises, group 2: stretching exercises alone). The outcome measures were pain measured with visual analogue scale (VAS), algometry on the trigger point, algometric difference, thermographic difference, and thermal asymmetry. Comparison was made within and between the groups pre- and post-therapeutically and 3 weeks after therapy. RESULTS: Mean pain values decreased more significantly in group 1 from baseline to 3 weeks follow up (7.54-3.06) while these values were 7.03-5.19 in group 2 (P < 0.05). Group comparisons revealed significant favorable differences in group 1 patients in terms of all other parameters at the first and the second evaluation post therapeutically (P < 0.05). CONCLUSIONS: LLLT seemed to be beneficial for pain in MPS by using algometry and thermography.     

A comparison of thermocouple and infrared thermographic analysis of temperature rise on the root surface during the continuous wave of condensation technique

AIM: This study was designed to use two methods of temperature measurement to analyse and quantify the in vitro root surface temperature changes during the initial stage of the continuous wave technique of obturation of 17 single-rooted premolar teeth with standard canal preparations. METHODOLOGY: A model was designed to allow simultaneous temperature measurement with both thermocouples and an infrared thermal imaging system. Two thermocouples were placed on the root surface, one coronally and the other near the root apex. A series of thermal images were recorded by an infrared thermal imaging camera during the downpack procedure. RESULTS: The mean temperature rises on the root surface, as measured by the two thermocouples, averaged 13.9 degrees C over the period of study, whilst the infrared thermal imaging system measured an average rise of 28.4 degrees C at the same sites. Temperatures at the more apical point were higher than those measured coronally. After the first wave of condensation, the second activation of the plugger in the canal prior to its removal always resulted in a secondary rise in temperature. The thermal imaging system detected areas of greater temperature change distant from the two selected thermocouple sites. CONCLUSIONS: The continuous wave technique of obturation may result in high temperatures on the external root surface. Infrared thermography is a useful device for mapping patterns of temperature change over a large area.     

Localized form of multiple glomus tumors: report of the first case showing partial involution

We recently examined a boy with relatively large multiple glomus tumors on the left scapular region. Histologic examination revealed a typical non-capsulated glomangioma in the middle and deep dermis; by electron microscopic examination, the tumor cells were seen to exhibit a characteristic smooth muscle cell structure. Thermographic examination revealed the higher temperature of the tumor. Within a year, the tumor showed a partial involution. We think this is the first report of multiple glomus tumor showing a partial involution.

A comparison of thermography and electromyography in the diagnosis of cervical radiculopathy

We studied 20 asymptomatic control subjects and 14 patients with clinically unequivocal cervical radiculopathy to compare the diagnostic value of thermography with that of electromyography. We measured the average skin temperature of designated regions over the neck, shoulder, and upper extremities. We then compared the temperature between corresponding regions of the two limbs, and between fingers innervated by different roots in the same hand. Thermography was abnormal in 6 patients (43%), whereas electromyography was abnormal in 10 (71%). Thermographic abnormalities were seen only in the hands and fingers, and the pattern did not follow the dermatome of the clinically involved cervical root. When compared to electromyography, thermography provided no additional diagnostic information. Thus, thermography does not have an established role in the evaluation of patients with cervical radiculopathy.
