In order to determine the prevalence and severity of hepatic osteodystrophy by noninvasive means we compared 115 consecutive ambulant patients with histologically proven chronic liver disease to 113 age and sex matched control subjects. Methods used included the assessment offracture prevalence rates, spinal radiography, and measurements of bone mineral density in the spine and the forearm. Spinal and peripheral fractures were more prevalent in the patients than in the control subjects (p<003 and p<001 respectively).

The relative contributions of altered gastric motor function and Helicobacter pylori-associated active chronic gastritis to the pathogenesis of functional dyspepsia are controversial. We therefore evaluated scintigraphically the intragastric distribution and gastric emptying of a mixed solid-liquid meal in 75 patients with functional dyspepsia; patients were subdivided on the basis of both specific symptom clusters and the presence or absence of H. pylori gastritis. Twenty-one (28%) patients displayed abnormal solid and/or liquid gastric emptying, with prolonged solid lag time the most prominent alteration detected. The number of patients with abnormal scintigraphic patterns increased to 36 (48%) when intragastric distribution parameters (fundal half-emptying time and antral maximal fraction) were examined. Although patients with reflux-like dyspepsia (N = 36) demonstrated significantly slower rates of liquid emptying at 45 and 70 min and a higher prevalence of abnormal liquid intragastric distribution when compared to patients with motility-like dyspepsia (N = 39) or to controls (N = 34), the absolute differences were small and unlikely to be of clinical significance. Patients without H. pylori gastritis (N = 50) demonstrated a significantly more prolonged solid lag time when compared to those with H. pylori gastritis (N = 25), but the difference was small and there were no other differences between these two subgroups.(ABSTRACT TRUNCATED AT 250 WORDS)
