[Argyria: new physio-pathological and therapeutic hypothesis].

The authors describe a case of sistemic argyria. They suggest a common physiopatologic mechanism with Wilson disease and they consider the utilization of penicillamine as a ligand for the silver, since there are not other available valid treatments.

[Scintigraphy using 99m-TC HM-PAO labeled autologous granulocytes in the diagnosis of Whipple's disease].

Whipple's disease is a systemic disease, mainly localized in the small intestine, that even today shows some difficulties about its etiopathogenesis and diagnosis. The surveys usually used in the diagnosis, among which the biopsy is an indispensable test, have some limits particularly in follow-up. The 99mTc-HM-PAO labelled granulocytes scintigraphy may be a useful alternative method in the evaluation of location and extension of the Whipple's disease.

[Treatment of duodenal ulcer with rosaprostol in patients resistant to treatment with anti-H2].

The results obtained with the combined treatment Rosaprostol + anti-H2 in 10 patients with duodenal ulcer previously treated with insufficient results with anti-H2 drugs are described (in comparison with other 10 patients under the same conditions treated with anti-H2 alone). The results are clearly favourable (statistical significance) for Rosaprostol. The drug was well tolerated.
