Energy expenditure and nutritional adequacy of rehabilitation paraplegics with asymptomatic bacteriuria and pressure sores.

OBJECTIVE: To measure resting energy expenditure (REE) in a group of people with postacute paraplegia, quantify the impact of asymptomatic bacteriuria and pressure sore(s) on patients' metabolic rate, and estimate the adequacy of patients' nutritional intakes to preserve patients' protein levels. MATERIAL AND METHODS: Ten males with post-acute paraplegia aged 42.1+/-18.7 years. We evaluated: height, body mass index (BMI), resting energy expenditure (REE), total daily calorie requirement (E), 24-h urine creatinine excretion (Cru), creatinine index (CI), and nitrogen balance (NB). RESULTS: Subjects with paraplegia showed high erythrocyte sedimentation rates. As a group, they had normal resting calorie consumption when REE was normalized for unit of urine creatinine (REE/Cru), it was higher in patients than in controls. Six of the 10 patients had a low calorie intake: of these only three had a negative nitrogen balance. CONCLUSION: In conclusion, the resting energy expenditure of the subjects with significant bacteriuria and pressure sore(s) of 23.7 kcal/kg/day suggests that a large portion of patients may have an inadequate calorie protein intake to preserve their nutritional status. The clinical significance of this study is that 28.5 kcal/kg/day may be the lower calorie threshold to meet the metabolic demands of people with apyretic paraplegia with bacteriuria and pressure sore(s).

Breast cancer screening in an urban black population. A preliminary report.

Breast cancer is a major cause of death among black women. At Cook County Hospital in Chicago, a hospital serving a predominantly black population, only 31% of breast cancers were localized at the time of diagnosis in the years 1980-1983. A survey of patient records in the largest primary care clinic in the hospital revealed that only 2% of eligible patients had received mammograms in 1982. A nurse-run breast cancer detection program was begun in mid-1983. Since that time the proportion of women who have received periodic breast examinations has increased from 26% to 46% (P less than 0.001) and periodic mammograms have increased from 2% to 41% (P less than 0.001). The proportion of women having received breast self-examination teaching increased from 10% to 58% (P less than 0.001). The proportion of localized breast cancer was significantly greater for those women whose cancer was diagnosed through the screening program (44 of 72, 61%) compared to other clinical areas (71 of 213, 33%) in the years 1984 through 1986 (P less than 0.001). There has been a significant increase in the percentage of localized breast cancer at Cook County Hospital comparing 1980-1983 statistics (31%), before the Breast Cancer Detection Program was fully established, with 1984-1986 statistics (40%) (P less than 0.02).

Pancreatic tumor imaging by III generation CT, gray-scale ultrasound and improved angiography.

Thanks to computed tomography (CT) and gray-scale ultrasounds the possibilities of morphological diagnosis in pancreatic disease have improved. Nevertheless, only a part of the potential performances of this practice is known and especially for ultrasounds, where only an expert eye can properly read the resulting images. With the help of pictures we hereby deal with the above-mentioned procedures in the demonstration of a pancreatic neoplasm. The possible integration with other more invasive methods was verified compared to pancreatic angiography. The latter is irreplaceable in the presurgical stage, and the method proposed by the authors can be useful when other methods cannot be employed.
