[XYY syndrome. Report of a case].

A sixteen year old boy was admitted to our department for delayed puberty. The personal history was not significant and physical examination revealed only a genital hypogonadism. The endocrinology study of the patient showed a hypogonadotropic hypogonadism.

[Bile salts, copper, ceruloplasmin in meal test].

Biliary salts determination after meal test is an useful liver function test. We evaluated both biliary salts and copper-ceruloplasmin after meal test in different liver diseases. Copper-ceruloplasmin determination does not seem to be useful in the diagnosis of liver diseases because copper has only partial hepatic clearance.

[Significance of the study of bile salts in acute and chronic liver disease].

The diagnostic value of fasting and after meal test total bile acid determination in control subjects and in patients suffering from chronic persistent and active hepatitis, fatty liver and cirrhosis has been evaluated with fluorimetric method. Our results demonstrated the good sensitivity of determination of bile acids after meal test in evaluating the different forms of liver damage.
