[Acute kidney failure following Cortinarius splendens (Fries) or "yellow clubbed foot" mushroom poisoning (so-called orellanus syndrome)].

Intoxications by cortinarii have only been recognized in recent years. Compared to other mushroom poisoning they are characterized by the long incubation time of up to ten days or more, and predominantly hepatorenal symptoms. In this paper the first two Swiss cases of intoxication with Cortinarius phlegmacium splendens are reported. The two patients ate two meals of this mushroom one week apart. Three days after the second meal the patients became acutely ill with severe lumbar pain, polyuria, polydipsia and constipation. Laboratory examinations revealed signs of hepato-renal toxicity with increase in serum creatinine, hyposthenuria and hyperbilirubinemia. Both patients recovered fully in the course of a further two weeks.
