[Mono-arthritis of uncertain etiology--a follow-up study].

78 patients in whom the cause of a monoarticular arthritis remained unclear after an initial workup were contacted for a follow-up interview (and an additional clinical examination in 64 cases) after 6 to 11 years (mean 8 years). The mean age at the onset of symptoms was 39 years, with 51% of the patients presenting in the range between 20 and 40 years. There was a slight male preponderance (56%).

Bile duct varices.

The diagnosis of biliary duct varices and portal vein occlusion should be considered when nodular or notched defects in the wall of the biliary duct system are shown by cholangiography or when pedunculated vascular structures in the bile ducts are seen at surgery. We present two cases of common hepatic and common bile duct varices due to portal vein occlusion.
