Purpose To explore the clinicopathological features, differential diagnosis of solitary bronchial papilloma, and its relation with and human papilloma virus infection.Methods Four cases of SBP were studied by routine histologic,immunohistochemical staining and in situ hybridization, together with review of the literature.Results One of four lesions was squamous cell papilloma, with focal malignant change of squamous cell carcinoma with microinvasion. The case was an old woman and the cancer located in central bronchus. Others were mixed squamous cell and glandular papilloma, and two cases with features of moderate cytologic atypia. The age ranged from 25 to 73 years (average 54), and tumors were located in the bronchi and segmental bronchi. Papillary arborizing connective tissue stalks were lined by both squamous and glandular epithelium. Four papillomas were exophytic, with one case inverted partly. Four cases were examined for HPV DNA and all were negative.Conclusions SBP in adults is a rare lung neoplasm. Based on uncommon cases association with malignant change, all endobronchial papillomas should be completely excised.

Objective To analyze the mortality in the aged patients with hip fractures who have been treated by operations. Methods We collected the clinical data of 349 aged patients (60 to 98 years old) with hip fracture who had been treated by operations from March 1999 to January 2008 in our hospital. Their overall mortality and one-year mortality were analyzed to find the causes for death. Results Thirty-one cases died and the overall mortality was 8.9% (31/349). Nineteen patients died within one year and the one-year mortality was 5.4% (19/349). Three patients died in hospital after surgery, 28 patients died in the follow-up period. Cardiac event, pulmonary dysfunction, cancer, cerebral vascular disease, hepatic cirrhosis, multiple organs dysfunction and infection were sequentially the major causes for death. Statistical results showed the factors which had definitely influenced the mortality were age and sex. Patients treated with proximal femoral nail anti-rotation (PFNA) had the lower mortality than with proximal femoral nail (PFN). Conclusions Operations can lead to a low mortality for aged patients with hip fractures. Ad-equate preparation and mini-invasive surgery can reduce the mortality.
