PURPOSE: The purpose of this work was to describe the positive predictive value of electron beam CT (EBCT) for diagnosis of solid renal tumors. METHOD: Among 11,932 consecutive patients undergoing screening EBCT, 27 cases met EBCT criteria for solid renal tumors. Twenty-six of 27 patients underwent surgery. RESULTS: Surgical pathology identified 25 solid renal tumors and 1 adrenal hemorrhage with thrombus. Twenty tumors were classified as T1N0M0, one was T2N0M0, and one was T3aN0M0. All tumor patients are clinically well at 1-41 months (mean 17 months) postoperatively. None of the patients had clinical signs or symptoms characteristic of renal malignancy. CONCLUSION: EBCT is an effective tool for detection of solid renal tumors in a healthy outpatient population (positive predictive value 0.96). The detection rate is low [0.2% (26/11,932) at our facility] in patients undergoing EBCT for other indications. The cost-effectiveness and sensitivity of this technique for solid renal tumor detection among various populations remain to be determined.

Attributes of the oral cavity as a site for basal body temperature measurements.

The thermal topography of the oral cavity of 11 women was mapped with thermocouples in early morning waking conditions. A reference thermocouple was placed in the vagina. No significant difference was found in the time required to reach a steady-state oral temperature and in the achieved steady-state temperature difference (Tv-To) in the preovulatory and postovulatory phases of the menstrual cycle. Location of the thermocouple in the oral cavity had a significant effect on steady-state temperature differences. After equilibration of oral thermometers, women breathed through their mouths for exactly five minutes. Mouths were closed and a second temperature equilibration phase was recorded. Mouth breathing had a significantly greater effect on the temperature of the anterior sublingual and dorsum of the tongue sites than on the posterior sublingual and buccal trough sites.

Strategic withdrawal from cigarette smoking.

Cigarette smoking can be viewed mainly as a psychological habit with accompanying pharmacological and social satisfactions and reinforcements. It is mainly a learned behavior, occurring in response to direct and indirect social pressures. Though each person's smoking habit is individualized, studies show that smokers find at least six psychological satisfactions in the habit: stimulation, handling, relaxation, tension reduction, craving and habit. To quit smoking, the individual must undergo physical and psychological withdrawal. Physical withdrawal symptoms last about a week but it may take months or years to restructure a life without cigarettes. Quitting is a long-term learning process involving a great deal of unconscious, constructive and painful conflict. One can stop smoking if the problem is attacked on a broad front, if one "burns one's bridges" behind him/her and if suitable satisfying alternatives and involvements are discovered. Physical exercise in the form of aerobics is proposed as an especially effective alternative behavior.
