Question: Abstract: A patient with severe chronic gastritis and duodenitis that clinically and endoscopically disappeared after an intestinal revascularization procedure is reported. Chronic intestinal ischemia appears to be a cause of gastritis as seen in this patient. 
Question: Does the abstract contain any numerical data?

Answer: No


Question: Abstract: Active forms of vitamin D3, 1 alpha-hydroxyvitamin D3 and 1 alpha,25-dihydroxyvitamin D3, were administered in an open-design study to 40 patients with psoriasis vulgaris in three ways: to 17 patients 1 alpha-hydroxyvitamin D3 was given orally at a dose of 1.0 micrograms/day for 6 months, to four patients 1 alpha,25-dihydroxyvitamin D3 was given orally at a dose of 0.5 microgram/day for 6 months, and 19 patients were given 1 alpha,25-dihydroxyvitamin D3 applied topically at concentration of 0.5 microgram/g of base for 8 weeks. Improvement was observed at the end of the individual study periods in 13 (76%) patients in Group 1 with a mean period of treatment (+/- SD) of 2.7 +/- 0.6 months, in one patient in Group 2 at 3 months after the start of treatment, and in 16 (84%) patients in Group 3 when the chemical was applied for 3.3 +/- 1.2 weeks. No side-effects were observed in any of these trials. These data suggest that psoriasis may respond to active metabolites of vitamin D3 and that abnormalities in vitamin D metabolism or in responsiveness of the skin cells to active metabolites of vitamin D may be involved in the pathogenesis of this skin disease.

Answer: Yes


Question: Abstract: The microbial flora of recurrently inflamed tonsils removed from 25 children with recurrent episodes of tonsillar pharyngitis were compared to flora of tonsils removed from 23 adults suffering from similar illness. More bacterial isolates per tonsil were recovered in adults (10.2 per tonsil) than in children (8.4 per tonsil). The difference between these groups was due to a higher recovery rate in adults of Bacteroides melaninogenicus group (1.6 isolates per adult, 0.8 per child) and Bacteroides fragilis group (0.4 per adult, 0.2 per child). Conversely, Group A beta-hemolytic streptococci were isolated in seven (28%) children as compared to their isolation in one (4%) adult. More isolates of beta-lactamase-producing organisms (BLPO) per tonsil were recovered in adults. Forty-three BLPO were detected in 21 (91%) of the 23 tonsils removed from adults (1.9 isolates per patient) as compared to 31 isolates in 16 (64%) of the 25 tonsils removed from children (1.2 isolates per patient) (P = 0.04). These findings suggest that the etiology of recurrent tonsillitis in adults may differ from that in children. The differences in the tonsillar flora may be due to the effect of many more courses of antimicrobials given over the years to adults and the changes in tonsillar tissue that occur in this age group.
