[A peculiar case of hypomagnesemia]. / Un singolare caso di ipomagnesemia.

An old man with previous resections of small intestine for infarction and sigmoid for adenocarcinoma presented vomit, vertigo, visual impairment, fatigue, serum non detectable, reduced cellular magnesium, no ECG alterations. For the lack of symptoms proportionate to this alteration, an adaptation to progressive decrease in cellular magnesium is hypothesized.

[Primary biliary cirrhosis and autoimmune hepatitis overlap syndrome. An early case]. / Sindrome di overlap tra epatite autoimmune e cirrosi biliare primitiva. Un caso precoce.

A 21-year old asymptomatic woman had accidental report of increased transaminases. Serologic tests were negative, autoimmune profile was positive for anti-nuclear, antimitochondrial antibodies and rheumatoid factor. Histology of the liver biopsy showed severe necro-inflammatory activity both in biliary epithelium and in intralobular area, suggesting primary biliary cirrhosis/autoimmune hepatitis overlap syndrome.
