    Notizen: Since January 2001, the European surveillance system on contact allergies (ESSCA) has developed a suitable infrastructure with the financial support of EU funding (QLK4-CT-2001–00343 and –2001–2812), and has started to collect patch test data. These comprise a standardized clinical history and patch test results with the European standard series, contributed by the 12 centres in 8 European countries listed above. So far, with the 2003 data collection not yet completed, 7636 patients’ test results have been pooled and analysed; current data pertaining to 2002 and 2003 will be presented. Anamnestic data reflect partly the specialties of some centres (e.g., the % of occupational and hand dermatitis ranging between 6 and 29% and 18 and 56%), partly different selection criteria or possibly also definitions (e.g., 7–32% with underlying atopic dermatitis, 40–69% of patients age 40+). The leading allergen was nickel sulfate (15.7%, age- and sex-standardized), with however, large inter-national variation (the lowest standardized prevalence, 9.7%, was observed in Gentofte, Denmark, where nickel regulation had long been introduced). The prevalence of contact allergy to Myroxylon Pereirae resin (7.8%) has almost reached the frequency found with the fragrance mix (8.3%). In the two centres using the True Test™, both percentages were even lower, which may be indicative of a systematic effect. Within a few years, ESSCA is expected to meet its objective of increased consumer safety by post-marketing surveillance by continuously monitoring contact allergy across Europe.

    Notizen: Since January 2001, the European Surveillance System on Contact Allergies (ESSCA), supported by European Union funding (contract QLK4-CT-2001-00343), has started to collect patch-test data. This comprises a standardized clinical history and the patch-test results using the European standard series, from 17 centres in 9 European countries listed above. In 2002 and 2003, 10 511 patients' test results have been pooled and analysed. The anamnestic data partly reflect the subspecialties of some centres. The most common allergen was nickel sulfate (17.3%); however, large international variations were observed. The prevalence of contact allergy to Myroxylon pereirae resin (balsam of Peru) (5.8%) is coming close to the frequency found with the fragrance mix (6.4%). Regarding contact allergy to chromium compounds, different frequencies were noted in the 2 centres focused on occupational dermatitis (2.3% in the FIOH versus 7.4% in the Nofer Institute). These most likely reflect the beneficial effect of addition of ferrous sulfate in one, but not the other country. As differences may partly be due to different patch-test reading, standardization may need to be refined further. By providing post-marketing surveillance in the field of contact allergy, ESSCA will meet its objective of increased consumer safety across Europe.

    Beschreibung / Inhaltsverzeichnis: Summary Objectives: The risk to suffer from natural latex allergy is increased in children with congenital neurogenic bladder dysfunction. We, therefore, evaluated whether or not a serologic screening for detection of sensitization to latex is reasonable in these children. Patients and Methods: 40 children aged from 6 months to 17 years were examined by specific questionnaire-based patient histories, and by determination of total serum immunoglobuline E (total IgE) and natural latex-specific serum immunoglobulin E (latex-IgE) by solid-phase immunoassays. Results: 5 children had a history of allergic reaction to rubber containing materials. In 10 children, latex-IgE was elevated 〉 0.35 kU/l, 6 out of these 10 children without a history of allergic reactions to rubber containing materials. There was a positive correlation of elevated latex-IgE values and the number of former surgical procedures (p 〈 0.006), while no correlation was found between elevated latex-IgE values and clean intermittent catheterization (p = 0.408). Conclusion: Compared to questionnaire-based patient histories, serologic screening examination including determination of latex-IgE values may better identify children at risk to suffer from sensitization to natural latex.
    Notizen: Zusammenfassung Fragestellung: Naturlatexallergien kommen bei Kindern mit angeborener neurogener Blasenentleerungsstörung gehäuft vor. Es wurde deshalb untersucht, ob bei dieser Patientengruppe ein serologisches Screening zur Erfassung einer Sensibilisierung gegenüber Naturlatex sinnvoll ist. Patienten und Methode: Untersucht wurden 40 Kinder im Alter von 6 Monaten bis 17 Jahren. Die Untersuchung umfaßte eine gezielte Anamneseerhebung durch Fragebogen sowie die Bestimmung des Gesamtimmunglobulin E (Gesamt-IgE) und des naturlatexspezifischen Immunglobulin E (Latex-IgE) im Serum durch Festphasenimmunoassays. Ergebnisse: 5 Kinder hatten anamnestisch Zeichen einer allergischen Reaktion nach Gummikontakt. 10 Kinder wiesen im Serum erhöhte Werte des Latex-IgE auf, wobei 6 dieser Kinder bisher noch keine Zeichen einer Latexallergie hatten. Pathologische Werte für das Latex-IgE korrelierten statistisch signifikant mit der Anzahl operativer Eingriffe (p 〈 0,0006), nicht aber mit einem durchgeführten sauber intermittierenden Einmalkatheterismus (p = 0,408). Schlußfolgerung: Im Vergleich zur alleinigen fragebogengestützen Anamneseerhebung können durch ein serologisches Screening mit Bestimmung des Latex-IgE mehr Kinder entdeckt werden, die durch eine Sensibilisierung gegenüber Naturlatex gefährdet sind.

    Notizen: Abstract The evaluation of pesticide-mineralising microorganisms to clean-up contaminated soils was studied with the widely applied and easily detectable compound atrazine, which is rapidly mineralised by several microorganisms including the Pseudomonas sp. strain Yaya 6. The rate of atrazine removal was proportional to the water content of the soil and the amount of bacteria added to the soil. In soil slurry, 6 mg atrazine kg soil−1 was eliminated within 1 day after application of 0.3 g dry weight inoculant biomass kg soil−1 and within 5 days when 0.003 g kg soil−1 was used. In partially saturated soil (60% of the maximal water-holding capacity) 15 mg atrazine kg soil−1 was eliminated within 2 days by 1 g biomass kg soil−1 and within 25 days when 0.01 g biomass kg soil−1 was used. In unsaturated soil, about 60% [U-ring-14C]atrazine was converted to 14CO2 within 14 days. Atrazine was very efficiently removed by the inoculant biomass, not only in soil that was freshly contaminated but also in soil aged with atrazine for up to 260 days. The bacteria exposed to atrazine in unsaturated sterile soil were still active after a starvation period of 240 days: 15 mg newly added atrazine kg soil−1 was eliminated within 5 days.

    Notizen: Abstract Objectives: To assess the health effects of hexamethylenetetramine (HMT) on the airways and the skin of workers in the chemical industry. Methods: A cross-sectional study was performed with 17 employees of a HMT-producing chemical plant and 16 control subjects from the plant. In addition, we examined 4 out of 5 subjects who had left the production for medical reasons during the last 10 years. Anamnestic data, total and specific IgE to four environmental allergens, lung function and bronchial responsiveness to methacholine were assessed by standard procedures. Skin prick tests (SPT) and patch tests were performed with known sensitizing substances and HMT 100 mg/ml and 2% pet and aq. Results: A high number of exposed subjects and controls reported symptoms during the previous year (64.7% vs 68.8%), most of them were not related to work. Work-related symptoms and objective parameters did not show differences between groups. No sensitizations to HMT as assessed by SPT or patch tests were found. Among those who had left the HMT production for medical reasons, 2 former baggers showed sensitizations to HMT by patch tests. These reported eczema during exposure but lost symptoms after removal from exposure. Geometric mean HMT concentrations as assessed by personal sampling were 0.3 [95% confidence intervals (CI) 0.1; 0.9] mg/m3 in shiftleaders and 0.6 (95% CI 0.3; 1.1) mg/m3 in baggers. Conclusion: High exposures to HMT may cause allergic contact dermatitis. There was no evidence of an increased risk for occupational asthma at mean airborne HMT concentrations below 1 mg/m3.

    Notizen: Abstract The braconid parasite,Apanteles flavipes (Cameron), was introduced into the Lower Rio Grande Valley of Texas in 1977 and has become established onDiatraea saccharalis (F.) attacking 4 species of host plants. Approximately 71% of the 26,971 adult parasites released were released in sugarcane,Saccharum officinarum L., with the remainder being released on field corn,Zea mays L., broomcorn,Sorghum vulgare technicum (Koern.) and Johnson grass,Sorghum halepense (L.). Recoveries indicate dispersal of at least 4 km from release sites.
