[Contact transendoscopic thermometry via a tube in active gastric and duodenal ulcer].

The temperature of the gastric and duodenal mucosa was taken by a contact method in 473 patients with active ulcer disease, 118 of them being with gastric ulcers and 355--with duodenal ulcers. Sixty four of the gastric ulcers were with superficial gastritis, 54 gastric ulcers were with atrophic gastritis, 298 duodenal ulcers--with superficial inflammatory process and 57 duodenal ulcers with atrophic inflammatory process. The control group consisted of 31 healthy subjects without ulcer niche. In all patients, the temperature of the gastric and duodenal mucosa and in the periulcer niche was transendoscopically taken, at 6 separate levels. Four determinations were performed at each level (at the lesser curvature, greater curvature, anterior and posterior walls). A higher temperature, as compared with the control group, was found in the presence of ulcer defect in the region of duodenum and stomach. In case of superficial inflammatory process no temperature change developed in the mucosa, thus maintaining a statistically significant discrepancy in the region of the ulcer niche. The atrophic process reduced the temperature in the gastric zone in case of active gastric ulcer. The atrophic inflammatory process, in case of active duodenal ulcer, had no statistically significant effect on the higher temperature in the zones of duodenum and pylorous (T1 and T2) in the sites of the ulcer and around it, very likely due to the less manifested atrophic process in the duodenal mucosa as compared with the gastric one.

Inaccuracy of liquid crystal thermometry to identify core temperature trends in postoperative adults.

In 71 adult postsurgical patients, simultaneous measurement of core (tympanic membrane) and shell (liquid crystal adhesive temperature strip) cutaneous temperature was assessed on admission and every 15 minutes throughout the recovery room stay. Tympanic membrane sensors were inserted into the ear and adhesive temperature strips were applied to the forehead. Although temperature strip temperatures on admission to the recovery room were correlated significantly with tympanic membrane temperatures on admission to the recovery room (r = 0.61, p less than 0.001), subsequent readings 15, 30, 45, and 60 minutes after admission demonstrated decreasing correlation coefficients. Moreover, changes in temperature strip temperatures over the first 15, 30, and 45 minutes of monitoring in the recovery room did not correlate significantly with changes in tympanic membrane temperatures over the same time period. These data suggest that shell temperature (temperature strip) is not a reliable or valid trend indicator of core temperature (tympanic membrane) in postanesthetic adults.

[Radiation thermometry used in the study of normal kidney functional activity].

In this paper, the results of use of active radiation heat flowmetry in the nephrological clinic are presented. Employment of rationalized loading tests permitted direct relationship to be established of radiation heat losses from the surface of the "open" kidney to the status of renal functions. Patterns of changes in the infrared radiation intensity have been ascertained in health and in the blockade of canalicular reabsorption. A hypothesis is documented about participation of autonomic system of regulation of renal bloodflow and glomerular filtration in thermostabilization of the kidney.

[Simultaneous study of the placental, myometrial and cervical circulations (indium 113 and anemometric thermometry). 3). Double blind study of the action of intravenous ritodrine during normal pregnancy].

The authors measure the changes in placental and myometrial blood flow using an isotope technique with Indium 113. They calculate an index of the variation in placental blood flow (I.V. D.P.) and an index of variation of myomoetfrial blood flow (I.V.D.M.) after injecting Ritodrine or a placebo between the 28th and the 36th week of pregnancy. This study was carried out in 26 normal women. At the same time using Brotanek's technique changes in the cervical blood flow were registered. No change in the placental, myometrial or cervical blood flows were noted while Ritodrine was being transfused intravenously.

Accuracy of infrared ear thermometry and traditional temperature methods in young children.

OBJECTIVE: To compare the accuracy of ear-based, rectal, and axillary temperature measurements in comparison to bladder temperature as a core reference. DESIGN: Repeated-measures comparison study. SETTINGS: Pediatric critical care settings in two tertiary care hospitals. PATIENTS: Thirty children, 1 to 45 months old (mean 16.6 months), who required bladder catheters for their care. OUTCOME MEASURES: Correlation and agreement (mean offset +/- SD) of ear-based, rectal, and axillary temperature measurements with bladder temperature. PROCEDURE: Ear-based measurements were made with three infrared thermometers in the core mode, both with and without an ear tug. All six readings were made in the same ear in randomized order. Bladder, rectal, and axillary temperatures were read from continuous digital displays immediately after each ear-based measurement. RESULTS: Ear-based readings correlated relatively well with bladder temperature (r = 0.80 to 0.87), but were lower by means of -0.3 degrees to -0.7 degrees C with moderately high variation (SD = 0.4 degrees to 0.5 degrees C) between children. Use of an ear tug did not affect the readings. Rectal temperature correlated well with bladder values (r = 0.93 to 0.97) and was usually slightly higher (mean offset = 0.2 +/- 0.2 [SD] degrees C), while axillary temperature correlated rather poorly (r = 0.59 to 0.64), with much lower and more variable readings (mean offset = 0.9 degrees +/- 0.6 degrees C). In regard to sensitivity, specificity, and predictive value in screening for fever, rectal readings performed very well, ear-based readings moderately well with some variation, and axillary readings poorly. CONCLUSIONS: The findings suggest that the additive core-mode adjustments in infrared ear thermometers are too low for young children, an ear tug is not an essential part of measurement technique, rectal temperature closely reflects bladder temperature, and axillary temperature is low and highly variable.

Tap in on ear thermometry.

In February 1992, nursing departments at The Mississauga Hospital, a 530-bed community hospital in Southern Ontario, purchased First Temp Genius ear thermometers to replace the electronic predictive thermometers then in use. Ear thermometers collect infrared heat radiation from the ear canal with a probe, then convert the radiation to a temperature reading. Although quick and easy to use with patients of all ages, there are nonetheless some issues concerning their use that still must be addressed.
