Hornet Sting-Induced Toxic Hepatitis

Aloe-induced Toxic Hepatitis

Aloe has been widely used in phytomedicine. Phytomedicine describes aloe as a herb which has anti-inflammatory, anti-proliferative, anti-aging effects. In recent years several cases of aloe-induced hepatotoxicity were reported. But its pharmacokinetics and toxicity are poorly described in the literature. Here we report three cases with aloe-induced toxic hepatitis. A 57-yr-old woman, a 62-yr-ol...

Nimesulide-induced hepatitis and toxic epidermal necrolysis.

Alverine induced toxic hepatitis: a case report.

Drug-induced hepatotoxicity is an important cause of hepatocellular injury. Hepatic necrosis may range from asymptomatic elevations in transaminases to fulminant hepatic failure and death. Alverine is an antispasmodic drug which is especially used in patients with irritable bowel syndrome. Only a few cases of alverine associated hepatotoxicity have been reported previously. We present the case ...

Anaphylactic reaction to white-faced hornet sting and elevated baseline (asymptomatic) serum tryptase.

Question: I recently evaluated an otherwise healthy 50-year-old man who experienced an anaphylactic reaction after a sting by a white-face hornet (witnessed). Skin testing was confirmatory. As part of the evaluation, a baseline serum tryptase was obtained 6 weeks after the initial reaction and was found to be elevated at 29 mg/L. The patient has no signs or symptoms of mastocytosis or other mas...

Poison and alarm: the Asian hornet Vespa velutina uses sting venom volatiles as an alarm pheromone.

In colonial organisms, alarm pheromones can provide a key fitness advantage by enhancing colony defence and warning of danger. Learning which species use alarm pheromone and the key compounds involved therefore enhances our understanding of how this important signal has evolved. However, our knowledge of alarm pheromones is more limited in the social wasps and hornets compared with the social b...
