[Validity of non-invasive deep body thermometry to evaluate thermoregulation].

We evaluated, as an index of thermoregulation and hemodynamics, the validity of deep body thermometry that measures deep tissue temperature transcutaneously by creating an area under an insulated thermistor probe of zero thermal flow between skin and subcutaneous tissue in 27 patients undergoing cardiac surgery. Deep body temperatures (DBT) were measured at the forehead (FH) and palm (P), and the DBT gradients (DBTFH-P) were compared with simultaneously measured mean arterial pressure (MAP), cardiac index (CI), systemic vascular resistance (SVR), the gradients (TESODBTP, TRECDBTP) of the esophageal and rectal temperatures and palm DBT during a three hour period after discontinuing cardiopulmonary bypass. Among the body temperature and hemodynamics measurements, the closest linear relationship was found between DBTFH-P and TESODBTP [0.35 + 0.95 x TESODBTP (degrees C), r = 0.98, SEE = 0.45, P < 0.0001]. There were no correlations between DBTFH-P and MAP, CI and SVR. We conclude that the measurement of DBTFH-P is useful as a reliable non-invasive method of monitoring core and shell temperature to evaluate thermoregulation.

Diagnostic value of finger thermometry in assessment of hand-arm vibration syndrome.

Finger thermometry and cold provocation test were performed in 90 chain saw workers and 58 healthy controls. The workers were grouped according to the Taylor-Pelmear scale of hand-arm vibration syndrome into subgroups 0, 1, 2, 3. The recovery rate reflected passive vasodilative ability. According to the results of the study, the test could differentiate the subjects with clinically manifest vibration-induced white fingers (stages 1, 2 and 3) from the controls. The discriminating threshold of recovery rate with regard to Raynaud's phenomenon was 90%. With that diagnostic limit the above method was sensitive and specific enough to verify vibration-induced vasospastic disorders and therefore could be recommended for their surveillance.

[Infrared tympanic thermometry--worse than reported?].

A comparison of parallel measurements of body temperature with infrared tympanic thermometry (First Temp 2000A) in both ears and with rectal mercury thermometer were performed in 100 patients with stroke (n = 60) or spinal cord injury (n = 40). Agreement between the two methods of temperature determination was assessed by calculating limits of agreement within which 95% (+/- 2 SD) of the individual differences would fall. Ear temperature was on average 0.3 +/- 1.0 (2 SD) degrees C above rectal temperature (p < 0.01). The upper and lower limits of agreement between the two methods were -0.7 degrees C and +1.3 degrees C, respectively. Mean difference between ear temperature in right and left ear was 0.0 +/- 0.7 (2 SD) degrees C. According to these results tympanic membrane temperature measured with First Temp 2000A appears to give clinical significant erroneous readings, and should be used with caution.

Continuous infrared thermometry of the nasal mucosa.

This study aims to continuously measure nasal mucosal temperature without interruption of nasal breathing using infrared thermometry. An infrared thermometer (Medi-Therm 310; Everest Interscience, Inc.) was directed at the nasal septum from a distance of 15 cm. Infrared radiation was continuously collected, then converted to an electrical signal proportional to the mucosal temperature and output to a chart recorder. In 70 subjects the mean nasal mucosal temperature was 30.4 +/- 2.0 degrees C on inspiration and 32.0 +/- 1.8 degrees C on expiration. Using multiple regression, nasal mucosal temperature was significantly related to atmospheric temperature (p < 0.0001) and inversely related to the airway patency of the ipsilateral nasal passage (p < 0.05).

[Contact thermometry of lesions in alopecia areata].

The contact thermometry has been performed at the center of lesions, at the periphery and at the adjoining healthy skin in 10 patients with alopecia areata (AA) of the scalp. The lowest temperature was recorded in the center of lesions (approximately 33.55 degrees C), slightly higher in the periphery (approximately 33.71 degrees C) and the highest in the adjoining healthy skin (approximately 34.01 degrees C). The authors suggest the skin temperature to be the result of the degree of vascularization. The obtained results were examined in reference to the results published elsewhere on the light and electronic microscopy of AA lesions where the changes in capillaries were found. Based on all the above, the authors consider the topical use of drugs that improve the peripheral circulation to be justified in the treatment of AA.

[Clinical thermometry. II. Current dilemmas].

The relevance of measuring core temperature for diagnosis and treatment of various diseases is generally acknowledged nowadays. Despite introduction of new techniques and markedly improved understanding of body temperature regulation and the pathophysiology of fever, several dilemmas remain to be elucidated in clinical thermometry. In the measurement and interpretation of body temperature, the many variables that influence core temperature, the site of temperature registration and the significance of an elevated or decreased core temperature should be taken into account. With every type of thermometer, good calibration and an adequate recording technique remain pivotal to obtain reliable and reproducible results.

[Simultaneous study of the placental, myometrial and cervical circulations (indium 113 and anemometric thermometry). 2. Effect of xanthinol nicotinate].

The authors have studied the action of nicotinate of xantinol on the placental, myometrial and cervical circulations using an isotope technique (Indium 113) and anemometric thermometry. They show that this product in every case increases the flow through the cervix and has little action on the flow through the placenta, except that in rare cases it lessens it. The action on the myometrial circulation varies from woman to woman. There is a significant negative statistical correlation between variation in the circulation through the cervix and the placenta.
