PURPOSE: This study was designed to determine the accuracy of physical examination (as judged by four-contrast defecography) for women with pelvic floor relaxation disorders. METHODS: Sixty-two women (mean age, 59 years) who had obstructed defecation or constipation, vaginal prolapse, urinary difficulty, or pelvic pain underwent four-contrast defecography. Oral, vaginal, bladder, and rectal contrast were administered selectively and fluoroscopy was performed. Radiographic findings were compared with physical examination diagnosis. RESULTS: Four-contrast defecography changed the diagnosis in 46 patients (75 percent); 26 percent of presumed cystoceles, 36 percent of enteroceles, and 25 percent of rectoceles were not present on defecography. Defecography also revealed unsuspected coexisting defects in addition to known abnormalities detected on physical examination. In contrast, when physical examination was negative for these defects, 63 percent of patients were found to have cystoceles, 46 percent to have enteroceles, and 73 percent to have rectoceles on four-contrast defecography. The discovery of Grade 2 or 3 unsuspected abnormalities was significant, especially so for enteroceles. For posterior vaginal eversions extending to or past the introitus, physical examination was accurate in only 61 percent. Physical examination of large anterior defects was more accurate, with 74 percent of patients being correctly diagnosed. CONCLUSIONS: Physical examination diagnosis of pelvic floor relaxation disorders is frequently inaccurate, especially for large vaginal eversions. Four-contrast defecography improves diagnostic accuracy, helps to identify all pelvic floor defects before surgery, and can assist with planning the correct operative approach.
To develop recommendations for the design of special foods for young children, we measured total daily energy consumption from semisolid food mixtures with energy densities of 1.67, 2.93, 4.18, or 6.28 kJ/g (0.4, 0.7, 1.0, or 1.5 kcal/g) and that were fed ad libitum three, four, or five times per day to 18 fully weaned children from 6 to 18 mo of age who were recovering in the hospital from malnutrition. The diets were generally indistinguishable by sensory qualities, and were fed in a randomized sequence. The mean amounts consumed (g.kg body wt-1.d-1) were significantly less with successively greater energy density of the diet (P < 0.001). The total daily consumption was approximately 16% more when the number of meals was increased from three to four per day, with energy density controlled for (P < 0.001), and 7% more when the feeding frequency rose from four to five meals per day (P = 0.005). The total daily energy intakes (kJ.kg body wt-1.d-1) increased significantly with the more concentrated diets (P < 0.001) and varied positively in relation to feeding frequency (P < 0.001). Approximately 15-20 min were required per meal for the children to reach satiety. The total amount of time required to feed the children each day was related to the number of meals served (P < 0.001) and not to energy density. Implications for child feeding are discussed.
