[Study of human papillomavirus via chemiluminescence technic and polymerase chain reaction in transitional cell carcinoma of the bladder].

Introduction: The exact ethiology of bladder carcinoma isn't yet known; an implication of human papillomavirus (HPV) has been recently hypothesized.

Materials And Methods: In this study HPV-DNA was investigated in urethral secretion and in bladder carcinoma of 37 patients. The analysis was performed by in vitro hybridization (chemiluminescent assay) and Polymerase Chain Reaction in order to detect HPV 6, 11, 16, 18, 31, 33 through specific primers.

[Cystic papillary tumors of the pancreas: 3 new cases].

Three cases of papillary cystic tumor of the pancreas (PCTP) are described. They were observed in two female patients aged 42 and 39, and in a male patient aged 55. A fine-needle ultrasound-guided aspiration biopsy was performed in the man.
