Hemolytic-Uremic Syndrome Associated with Bloody Diarrhea

ABSTRACT

The authors analysed 2,653 cases of transthoracic fine needle aspiration cytology of the lung to evaluate the diagnostic accuracy and its limitation. A comparison was made between the original cytologic and the final histologic diagnoses on 1,149 cases from 1,074 patients. A diagnosis of malignancy was established in 38.3% benign in 48.1%, atypical lesion in 2.3%, and inadequate one in 11.9% of the cases. Statistical data on cytologic diagnoses were as follows; specificity 98.9% sensitivity of procedure, 76.8% sensitivity of diagnosis, 95.5% false positive 5 cases false negative 18 cases predictive value for malignancy, 98.8% predictive value for benign lesion, 79.5% overall diagnostic efficiency, 87.5% typing accuracy in malignant tumor, 80%.
