TASK DEFINITION: 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.
PROBLEM: Abstract: A simple, safe technique for complete excision of pilonidal pathology and immediate fasciocutaneous rhomboid flap closure is presented. Twenty-five patients were treated. All wounds healed by first intention, with no patient remaining in the hospital for more than 10 days. Earlier cases were followed up for 2 years. No recurrence has yet been encountered.
Question: Does the abstract contain any numerical data?

SOLUTION: Yes

PROBLEM: Abstract: The alternative or classical pathways for complement system component C3 may be triggered by microorganisms and antigen-antibody complexes. In particular, an activated fragment of C3, C3b, covalently attaches to microorganisms or antigen-antibody complexes, which in turn bind to the C3b receptor, also known as complement receptor 1. The genes encoding the proteins that constitute the C3-activating enzymes have been cloned and mapped to a "complement activation" locus in the major histocompatibility complex, and we demonstrate in this study such a locus on the long arm of chromosome 1 at band 1q32.

PROBLEM: Abstract: The increasingly widespread use of cocaine in the United States has been accompanied and perhaps exacerbated by the misconception that the drug is not associated with serious medical complications. In particular, the potential for cocaine to precipitate life-threatening cardiac events needs to be reemphasized. We report the clinical and pathological findings in seven people in whom nonintravenous "recreational" use of cocaine was temporally related to acute myocardial infarction, ventricular tachycardia and fibrillation, myocarditis, sudden death, or a combination of these events. We also review data on 19 previously reported cases of cocaine-related cardiovascular disorders. Analysis of all 26 patients indicated the following findings: the cardiac consequences of cocaine abuse are not unique to parenteral use of the drug, since nearly all the patients took the drug intranasally; underlying heart disease is not a prerequisite for cocaine-related cardiac disorders; seizure activity, a well-documented noncardiac complication of cocaine abuse, is neither a prerequisite for, nor an accompanying feature of, cardiac toxicity of cocaine; and the cardiac consequences of cocaine are not limited to massive doses of the drug. Although the pathogenesis of cardiac toxicity of cocaine remains incompletely defined, available circumstantial evidence suggests that cocaine has medical consequences that are equal in importance to its well-documented psychosocial consequences.
