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: We have induced a basophil hypersensitivity reaction in the upper tarsal conjunctiva of the guinea pig by methods that induce a comparable basophil hypersensitivity reaction in the flank. The inflammatory cell infiltrate in this reaction contained large numbers of basophils and eosinophils with accompanying neutrophils and monocytes. Ocular tissue can serve as a priming site for systemic immunization and also for elicitation of a secondary flare after challenge with antigen. Very few inflammatory cells were observed in the cutaneous epithelium of either primary or secondary flares. In contrast, the mucosal stroma and epithelium contained large numbers of inflammatory cells (basophils, eosinophils, and neutrophils), suggesting directed cellular movement onto the ocular surface. The lesion of ocular basophil hypersensitivity in the guinea pig has features in common with two human eye diseases, vernal conjunctivitis and contact lens-associated giant papillary conjunctivitis. We hypothesize that the acute basophil hypersensitivity reactions of the conjunctiva are transformed into chronic inflammatory and proliferative states in vernal conjunctivitis and giant papillary conjunctivitis.

SOLUTION: No

PROBLEM: Abstract: Operative management of a patient with septic thrombosis from Candida organisms of the subclavian and central veins is described. Diagnosis was suspected on the basis of positive blood and catheter tip cultures, indium-labeled leukocyte scan, and bilateral upper extremity phlebograms. Venous thrombectomy with a Fogarty catheter of the upper extremity central veins was performed after a superior vena cava Greenfield filter had been placed to prevent pulmonary embolism. The thrombus culture was positive for Candida albicans, and the reestablishment of vein patency in conjunction with amphotericin B therapy resulted in cure. This technique allows a definitive diagnosis of septic central thrombosis to be made and reestablishment of vein patency may also enhance antibiotic therapy.

PROBLEM: Abstract: Five hemodialysis patients were treated with combined hemodialysis-hemoperfusion with their conventional hemodialyzer plus a 70-gram ultrathin collodion coated activated charcoal device for a total of 63 months. Indications for this therapy included pericarditis, peripheral neuropathy, clotting of conventional hemodialyzers and reduction of dialysis time and frequency. The outcome was beneficial in all cases and stable biochemical and hematological parameters were maintained. No increase in heparin requirements was noted and the therapy was thought to be cost-effective.
