Nucleolar protein p120 expression in oral carcinoma.

Nucleolar protein p120 is a proliferation-associated antigen expressed by cells in early G1 phase, identified by the monoclonal antibody FB-2. Its expression has been evaluated in breast and prostate cancer, and proved to be significantly correlated with other prognostic parameters. In oral pathology, p120 protein content is able to distinguish between non-neoplastic and malignant lesions. In the present study, the immunohistochemical expression of p120 protein was evaluated in fifty cases of oral squamous carcinoma and compared with histological grading, pTNM staging, DNA ploidy status and follow-up of the patients, in order to establish its prognostic value, p120 mean area was significantly correlated to all these parameters, apart from lymph node involvement, indicating the strong predictive potential of this marker. In conclusion, quantitative immunohistochemical analysis of p120 protein represents an easy and reliable method for the assessment of clinical outcome and the definition of risk groups in oral carcinoma.

[Contribution of echography in the diagnosis of gastro-esophageal reflux in children].

56 children, aged between 0-13 month, affected by chronic vomiting were evaluated both with ultrasound and radiological methods, in a double blind study. 22/56 children resulted to be affected by gastro-oesophageal reflux (GER) with upper GI series versus 18/56 with ultrasound. Four cases, ultrasound negative and X-ray positive, represented a borderline situation in which a mild gastro-oesophageal reflux is to be considered paraphysiological phenomenon. The accuracy and handleness of ultrasound evaluation in GER are emphasized.

[Transhepatic percutaneous cholangiography with the Chiba needle in diagnosis of cholestasis].

A technique originally described by Okuda has been employed to study 78 patients suffering from cholestatic syndrome. Visualization of the biliary system was obtained in 70 (89.7%). Of these, 65 presented dilatation of the bile ways whereas in 5, the biliary tree was normal. The 8 cases in which no visualization was obtained were later examined with other techniques and 6 proved to be suffering from intrahepatic cholestasis. In patients with extrahepatic obstruction, the biliary system was visualized in 97%, while in intrahepatic cholestasis, the percentage was 45.5%. The main indication for PTC is the speed at which intrahepatic cholestasis can be distinguished from the extrahepatic type; in the second event, it always pinpoints the site of the impediment, though less frequently the nature of the lesion and its extent. No complications requiring emergency laparotomy were ever encountered. Percutaneous transhepatic cholangiography with Chiba needle is a simple, reliable inexpensive method which gives excellent results in the study of patients with cholestatic syndrome.
