The GNS is a safe device with a low rate of intra-operative complications. The evolution of this nail system reduces postoperative complications, thus improving the results at follow-up and confirming that the Gamma3 Nail is a safe and predictable device to fix trochanteric fracture.

We report on two cases of simultaneous asymmetrical bilateral hip dislocation. Both patients were involved in car accidents. The first case is a 23-year-old man who had a bilateral hip dislocation, anterior on the right side and posterior on the left associated with bilateral femoral head fracture. The second case presented the same dislocations of the hips associated with acetabular fracture on the right side. Closed reduction of the hips was performed in both cases. In the first case the femoral head fragments was subsequently removed. In the second case internal fixation of the acetabular fracture was postponed.

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%.
