ABSTRACT
Vegetable-induced asthma is an uncommon hazard. We report an atopic housewife, in whom rhinoconjunctivitis and acute asthma were associated with two vegetables of taxonomically unrelated botanical families (Swiss chard/Chenopodiaceae family and green beans/legume family). Type I hypersensitivity to the antigens in Swiss chard and green beans was demonstrated by means of skin tests, histamine release test, and specific IgE determination by RAST. Bronchial responses after specific bronchial challenges indicated that Swiss chard and green beans might be the causative factor for the acute asthma.

Persulphate salts, which are common constituents of hair bleaches, have occasionally been reported to cause occupational asthma in hairdressers. We describe the clinical and immunological studies carried out in a hairdresser who developed cutaneous and respiratory symptoms, about 1 year after being employed in a hairdressing salon. Skin prick tests with 1:5 w/v potassium and sodium persulphate extracts were positive in our patient at 15 min and negative in control subjects. The European standard contactans (ECDRG) and a battery of hairdressing agents were patch tested with positive result to KATHON CG (isothiazolinone). The methacholine-inhalation test showed airway hyperresponsiveness. Bronchial provocation test with a 1:50 w/v potassium persulphate extract elicited a nonimmediate asthmatic reaction, followed by recurrent nocturnal fall in FEV1 lasting up to 3 days after the test. Plethysmography results revealed air trapping caused by a marked increase of airway resistance 3 h after the specific bronchial challenge. Histamine release test was not conclusive, and the determinations of specific IgA, IgM, IgG and IgG subclasses by EIA and IgE by RAST against persulphate salts were negative.

The Spanish National Health Service, largely represented by INSALUD, covers at present over 98% of the Spanish population. Services are free at the point of delivery with exception of prescription charges. The patients contribution towards the price of their medicines is approximately 40% of the cost of the drug for most ethical preparations. Non-prescription drugs are not reimbursed by the National Health Service. Pensioners and the disabled are exempt from prescription charges. Prescription analysis or monitoring is possible within INSALUD because of the necessity to reimburse pharmacists for the prescriptions they dispense, monthly batches of prescriptions are processed. The Drug Data Bank possesses three databases that may be used for prescription analysis, these are ESPES, ECOM and PACTIV. Information from these databases is used by external workers in: drug Monitoring Centres for Adverse Drug Reactions; the Spanish Collaborative Study on drug-induced birth effects; drug utilization research workers; INSALUD also produces reports on drug prescribing and these have a particular emphasis on expenditure; the General Directorate of Pharmacy also use these databases for their policy making on issues related to, and derived from prescribing.

A survey of the number and characteristics of Drug and Therapeutics Committees (DTCs) operating in hospitals in Ireland was conducted in 1984. Just under half of the hospitals surveyed had a DTC and half of those had been formed after 1981. Pharmacists and consultant medical staff were present on every DTC and the latter also chaired most DTCs. Formularies or limited lists had been drawn up by half the DTCs identified and the most frequently discussed topics at DTC meetings were concerned with expenditure control. These findings are discussed and compared with the experience of DTC formation and operation in other countries.
