SUMMARY Radionuclide gastric emptying studies using 99m-Tc human serum albumin egg omelette have been carried out in 10 long distance runners at rest and during a 90 minute run at sustained speed. Resting values are compared with controls comprising 10 sedentary subjects. Runners show a significantly accelerated basal gastric emptying (runners tl/2=67-7 (5 9) min; sedentaries tl/2=85 3 (4'5) min, p

The aim of this study was to assess the influence of the normal menstrual cycle and of menopause on the gastric emptying rate of solids. Gastric emptying was studied in 15 premenopausal and ten postmenopausal women with an isotopic technique after the ingestion of a radiolabelled test meal. Premenopausal women were studied twice: within 1 week prior to menses and again 1 week after onset of menses. Postmenopausal women were studied only once. The emptying curves of the solid component of the meal fitted a linear model. The half-emptying time was 78 +/- 5 min during the follicular phase, 75 +/- 7 min during the luteal phase and 76 +/- 6 min in postmenopausal women (differences not statistically significant). The mean percentages of the meal retained in the stomach at different time intervals were also similar in the three groups. These results suggest that the menstrual cycle does not influence the gastric emptying rate of solids, which remains unchanged in relation to the follicular phase or after menopause.

Intramural hematoma of the cecum is a rare complication of blunt abdominal trauma. We report two patients who presented with cecal hematoma after a fall and a traffic accident, respectively. Diagnosis was by abdominal computed tomographic scan. Patients were operated on 24 and 36 hours after the injury because of sudden clinical deterioration and hemoperitoneum, respectively. The patients had a large cecal intramural hematoma that progressed to the ascending colon by dissection of the teniae coli. Emergency right hemicolectomy was followed by uneventful recovery in both patients. Only six previously reported cases of cecal intramural hematoma were found, and in all cases a right hemicolectomy was performed. In conclusion, in contrast to hematomas located in other sections of the gastrointestinal tract, early surgical treatment for intramural hematoma of the cecum is recommended.
