Tumor extension along percutaneous transhepatic biliary drainage tracts.

Percutaneous Transhepatic Biliary Catheterization is commonly employed in the diagnosis and management of obstructive jaundice associated with malignant lesions. Tumor manipulation as an effort to obtain a histological diagnosis or to establish short or long-term internal-external biliary drainage is liable to disseminate the malignancy along the catheter tract. Two cases of malignant seeding of the catheter tract after biliary drainage have been observed.

Detailed evaluation of angiographic findings in the surgical assessment of resectability for pancreatic cancer.

The role of angiography as a diagnostic approach and surgical assessment of resectability in pancreatic cancer patients is considered. Pre-operative arteriography of the celiac axis and superior mesenteric artery was performed in 27 patients with surgically proved pancreatic cancer. The operatibility of each patient was assessed according to arteriographic findings.

Pancreatic carcinoma in childhood: case report of long survival and review of the literature.

[Hyperinsulinism and insulin resistance in the polycystic ovary syndrome as tested with tolbutamide].

The aim of this research was to study both insulin secretion and insulin resistance index (IRI) in seventeen females, aged 16-30, affected by polycystic ovarian syndrome. The diagnosis was made using clinical, hormonal, radiological and echographic criteria. Eight healthy women, carefully matched with our patients for age and for statistical obesity incidence, were studied as controls.

[Intravenous glucose tolerance test in the polycystic ovary syndrome].

The problem of hyperinsulinism and insulin resistance, previously observed by us in PCOS using the tolbutamide test, was studied in the present research using intravenous glucose tolerance test (IVGTT). 16 women (3 obese) aged 14-34 years, affected by PCOS, were studied. The diagnosis of PCOS was made using clinical, hormonal, radiologic and echographic criteria.
