Indicate the presence of numerical data in the abstract (whether numerical data plays a key role in medical records), solely using the information from the abstract.

Input: Consider Input: Abstract: Pillars of calcification are rarely found in the skin. An interesting case is described where rows of new bone developed in the skin which had been grafted 31 years previously to cover partial skin thickness burns of the shin. The problems of heterotropic ossification are discussed.

Input: Consider Input: Abstract: To investigate whether IgG antinuclear antibodies have cross-reactive rheumatoid factor activity, monoclonal IgG antibodies to DNA and Sm from autoimmune MRL-lpr/lpr mice were assayed by ELISA for binding to IgG antigens. Of the nine anti-DNA and anti-Sm monoclonals tested, six showed significant binding to affinity-purified rabbit IgG (RIgG) and human IgG (HIgG). To confirm that cross-reactivities were due to a single antibody, immunoabsorption of a representative polyspecific monoclonal termed C11 (anti-DNA, anti-Sm) on either Sepharose-DNA or Sepharose-RIgG resulted in marked loss of activity to the three antigens DNA, Sm and RIgG compared with immunoabsorption on Sepharose-bovine serum albumin. The monomolecular nature of the cross-reacting antibody was also suggested by inhibition analysis of C11; DNA inhibited C11 binding to RIgG 64%, whereas Sm inhibited binding to RIgG 33%. Aggregated RIgG and HIgG, however, did not inhibit binding of C11 to DNA, Sm, or solid-phase RIgG, probably reflecting the low affinity of this antibody for fluid phase Ig. Together, these findings suggest that antinuclear autoantibodies of the IgG, as well as the IgM, class have polyspecific IgG binding activity and suggest that IgG antinuclear antibodies may emerge from rheumatoid factor responses.

Input: Consider Input: Abstract: Colonoscopy is used in the differential diagnosis of inflammatory bowel disease but its accuracy and the "weight" of the various endoscopic signs have not been assessed. In a prospective study 357 patients with 606 colonoscopies, in whom the endoscopic appearances were those of ulcerative colitis, Crohn's colitis, or indeterminate colitis, were followed-up for an average period of 22 mo. A final, definite, endoscopy-independent diagnosis was reached by means of autopsy, surgery, or histology on biopsy in 71% of patients. Accuracy of colonoscopy was 89%, with 4% errors and 7% indeterminate diagnoses. Errors were more frequent in severe inflammatory activity (9%). The most useful endoscopic features in this differential diagnosis were discontinuous involvement, anal lesions, and cobblestoning of mucosa for Crohn's disease, and erosions or microulcers and granularity for ulcerative colitis. After selecting the endoscopic features with best predictive value, an "endoscopic score" was calculated by means of "likelihood ratios."
