Case Reports
Anaphylactic shock by rupture of hydatid hepatic cyst. Follow-up by specific IgE serum antibodies.
Total and specific serum IgE antibodies were estimated in a 68-year-old woman with anaphylactic shock due to spontaneous rupture of hydatid cyst of the liver. After she had recovered, an abdominal ultrasonography showed a cyst, 10 x 15 cm, in the right hepatic lobe. The cyst was surgically removed. Antihydatid IgE in the acute phase and periodically after surgical intervention, determined by Phadezym RAST, Pharmacia, and Pharmacia CAP system (a new solid-phase immunoassay, fully automated, for the titration of specific IgE with greater sensitivity in the detection of low IgE antibody levels), showed decreasing antihydatid IgE antibodies on day 10 after surgical intervention and may thus serve to monitor the evolution of hydatid disease.

Comparative Study
Clinical evaluation of in vitro leukocyte histamine release in allergy to muscle relaxant drugs.
We have evaluated the in vitro leukocyte histamine release tests for the diagnosis of allergy to muscle relaxant drugs in 40 patients (Group A) and a control group of 44 subjects with negative leukocyte histamine release (Group B). Non-IgE dependent histamine release, expressed as a percentage of the total blood histamine, was 3.94% +/- 0.49 in Group B. The upper limit of positivity was estimated to be 5% (mean + 2 SD). ⋯ Of 20 M2. All of the 10 cases had negative ID tests with M2. Three of these patients subsequently underwent general anesthesia with the muscle relaxant chosen as harmless (M2) without any clinical reaction.
