The effect of external pressure on skin temperature distribution by thermography.

1) Serial thermograms were taken after the application of various intensities and durations of localized pressure on the medial surface of the human forearm. 2) Thermal response of the body surface to localized pressure was quantified. 3) It was found that usually a time period of between 1 to 3 minutes elapsed before the body surface attained a maximum elevation of temperature from the time the localized pressure is removed. 4) It was found that increased intensity of pressure (5 psi vs. 3 psi) and longer duration (20 minutes vs. 10 minutes) caused larger thermal responses. 5) It is suggested that high resolution medical thermography may eventually become a useful tool in the fitting of prosthetic and orthotic devices and for the prediction of pressure sores formation so prophylactic measures can be started immediately on immobilized patients.

Pulmonary toxicity of methyl methacrylate vapors: an environmental study.

The toxicity of methyl methacrylate vapors was tested using a mouse model. Mice were exposed for prolonged periods (2 hr twice daily for 10 days) to high doses (1,500 ppm) under atmospheric oxygen and carbon dioxide concentrations. Histologic examination of the lungs, liver, heart, and kidney showed no evidence of damage.

The safety of cement fixation in the cervical spine. Studies of a rabbit model.

Immediate postoperative ambulation of patients with terminal neoplastic disease of the cervical spine can be permitted by vertebral stabilization with wire reinforced with polymethylmethacrylate. Precautions are necessary to avoid a temperature rise during cement polymerization and prevent vasular or nerve damage. Experiments on 20 rabbits and 2 human cadavers indicate that temperature at the cement-lamina interface can rise as high as 90 degrees while temperature under the intact lamina measures only 50 degrees. Precooling and insulation with Gelfoam may prevent heat injury to spinal cord.
