background: acute appendicitis is the most common surgical emergency of the childhood. its diagnosis is really challenging. a constellation of through history taking, physical examination, radiographic investigations, and laboratory analysis should be used to balance the risk of delayed operative intervention against the removal of a normal appendix. here a case with misdiagnosis of acute appen...

Two ectomycorrhizal macrofungal Amanita species of the section Lepidella, A. strobiliformis and A. solitaria, were found to hyperaccumulate silver (Ag). All samples were collected from non-argentiferous areas with background Ag content in soils (0.07-1.01 mgkg(-1) Ag). The Ag contents of both Amanita species were mostly in the range of 200-700 mgkg(-1)D.W. with the highest Ag content of 1253 mg...

A growing number of molecular studies show that many fungi have phylogeographic structures and that their distinct lineages are usually limited to different continents. As a conservative test of the extent to which wind-dispersed mycorrhizal fungi may exhibit phylogeographic structure, we chose to study Amanita muscaria, a host-generalist, widespread, wind-dispersed fungus. In this paper, we do...

INTRODUCTION Amanita phalloides and paracetamol intoxications are responsible for the majority of acute liver failures. AIM To assess survival outcomes and to analyse risk factors affecting survival in the studied group. MATERIAL AND METHODS Of 1369 liver transplantations performed in the Department of General, Transplant, and Liver Surgery, Medical University of Warsaw before December 2013...

Amanita calida is illustrated and described from collections made in Andalusia Catalonia, a Mediterranean environment, associated with Quercus. Macroscopically, this species characterized by whitish, beige to grayish cuticle, sometimes prominent darker brown umbo, widely striated margin of the pileus, very elongated stipe proportion diameter whitish or similar but fainter shades those pileus; s...

Mushroom poisoning is a relatively rare cause of acute liver failure (ALF). The present paper analyzes the pathogenesis, clinical features, prognostic indicators, and therapeutic strategies of ALF secondary to ingestion of Amanita phalloides, which represents the most common and deadly cause of mushroom poisoning. Liver damage from Amanita phalloides is related to the amanitins, powerful toxins...

The determination of the two isomers amavadin and other V species in Amanita muscaria with HPLC-ICPMS.

We have recently developed a method for the analysis of toxins in single specimens of the mush­ room Amanita phalloides (Fr.) Seer.1. Separation of the different toxins was achieved by column chro­ matography, on Sephadex LH20 in water, of a methanolic extract of fresh or dried mushrooms, followed by further purification on thinlayers of silica gel, spectrophotometric evaluation, and, final­ ly...
