Tecniche di campionamento di sostanze bioattive da aculei di Scorpaena porcus

Nel presente report vengono descritte le tecniche utilizzate per l'estrazione del veleno dagli aculei della specie ittica Scorpaena porcus. Gli estratti grezzi ottenuti sono successivamente processati al fine di ottenere frazioni da utilizzare in saggi biochimici, per lo studio di possibili attività biologiche.

A Very Big Hand Is a Very Big Problem: Soft-Tissue Infection, Venous Thrombosis, or Just an Insect Sting?

A 67-year-old woman developed severe edema of her right hand and forearm, for which she was treated with antibiotics, without benefit. The echography excluded a venous thrombosis. Subsequently, she referred a wasp sting before the development of the edema. Specific Hymenoptera venom immunoglobulin E (IgE) was found to be positive for paper wasp and yellow jacket. A large local reaction (LLR) was diagnosed due to the hymenoptera sting. Self-injectable epinephrine was prescribed for possible, though unlikely, systemic reactions following hymenoptera stings.
