A prospective and multicenter safety-monitoring study of a short up-dosing schedule of immunotherapy with a mass-units-standardized extract of mites.

A prospective, multicenter pharmacovigilance study was carried out to evaluate the safety of a new 7-dose treatment schedule of subcutaneous immunotherapy as opposed to the conventional 13 doses normally recommended. The study was carried out in 14 centers and included 261 patients (children and adults) with respiratory allergic disease due to sensitization to mites (Dermatophagoides pteronyssinus and/or farinae). A total of 2290 doses were administered under the direct supervision of the participating specialists.

Anaphylaxis to erythromycin.

Background: Erythromycin and its salts belong to the larger class of macrolides. Erythromycin is well tolerated. The most common side effects are gastrointestinal distress, nausea, and vomiting, which are dose related.

Labiatae allergy: systemic reactions due to ingestion of oregano and thyme.

Background: There are no cases described in the medical literature of systemic allergic reactions due to oregano (Origanum vulgare) or thyme (Thymus vulgaris). These herbs belong to the Lamiaceae (Labiatae) family which comprises other plants such as hyssop (Hyssopus officinalis), basil (Ocimum basilicum), marjoram (Origanum majorana), mint (Mentha piperita), sage (Salvia officinalis) and lavender (Lavandula officinalis).

Objective: We describe three systemic allergic reactions caused by oregano and thyme in the same patient.

Mustard allergy: three cases of systemic reaction to ingestion of mustard sauce.

Very few cases of hypersensitivity due to ingestion of mustard have been described in the literature, although this spice enjoys widespread use. We present three cases of anaphylactic reactions to ingestion of a small amount of mustard sauce. In our patients we performed skin prick tests with mustard and with the rest of the vegetables belonging to the Cruciferae family.
