[The treatment of intestinal intussusception in childhood]

Intussusception is one of the most frequent cause of mechanical bowel obstruction in children. On the basis of clinical features and diagnosis operations were conducted on 26 children. In 21, the treatment was manual disinvagination. In 5, pathomorphological changes of the walls of the invaginated portion suggested the intestinal resection.

Bronchial brushing and biopsy: a comparative evaluation in diagnosing visible bronchial lesions

One hundred and forty patients underwent 142 brushings and conventional biopsies of suspected malignant lesions of the lung through a fibreoptic bronchoscope. Both samples were taken from the same area. One hundred and three patients showed positive results on brushing and 90 on biopsy. Thirty-nine diagnoses were negative on brushing and 52 on biopsy. A correct cell typing was obtained in 105 of 109 diagnoses of malignancy. Final diagnoses showed 118 malignant lesions and 22 benign conditions. False positives were respectively, 2 on brushing and 1 on biopsy, while false negatives were 17 on brushing and 30 on biopsy. Brushing showed higher sensitivity (85.5%) and accuracy (86.6%) than biopsy. A combination of the two techniques gives an accuracy rate of 94.3%.
