    Notes: Background  Occupational skin diseases (OSDs) account for a large portion of occupational diseases in Europe, but population-based epidemiological studies are missing. Objectives  We analysed the initial reports of OSDs in our register of OSDs in Northern Bavaria (BKH-N). Methods  A total of 5285 cases were assessed prospectively and registered from 1990 to 1999. As the German Federal Employment Office provides specific occupational data in relation to the total employed population of Northern Bavaria, it was possible to conduct a population-based study that investigated the trend in incidence rates between two study periods (1990–92 and 1993–99) in 24 different occupational groups. Results  A total of 3097 cases of OSD (median age 25 years) were recorded in the 24 occupational groups. There was a significant decline (P 〈 0·001) in the overall incidence rate of OSD with 10·7 cases per 10,000 workers per year for the first study period and 4·9 cases per 10,000 workers per year for the second study period. This general trend in incidence rates was also significant for hairdressers and barbers, bakers, health-care workers, cooks and metal processors. Conclusions  The BKH-N provides national data based on the notification of OSDs in Germany. The results demonstrate the rank of occupations hazardous for the skin and are helpful for defining target groups for prevention.

    Notes: Objectives:  To analyse the yearly incidence rates and causes of occupational skin diseases (OSD) in different metal-working industries.Methods:  Between 1990 and 1999, all new cases of OSD and their causes were prospectively recorded in all metal-working enterprises of Northern Bavaria. We calculated the incidence rates according to the average employed population. Furthermore, we analysed the different allergens, irritants and constitutional factors (e.g. atopy) in the affected metal workers.Results:  In metal workers, a total of 700 OSDs were registered which comprise 18.8% of all OSDs in our register. They were classified into metal-surface processors (260 OSDs, yearly incidence per 10,000 employees = 10.4), metal processors (129 OSDs, 5.9), locksmiths and automobile mechanics (119 OSDs, 2.5), electrical industry (69 OSDs, 1.4), machinists (47 OSDs, 11.6), mechanics (40 OSDs, 6.6), electroplaters (22 OSDs, 20.6) and solderers (14 OSDs, 13.4). The proportion between allergic (ACD) and irritant contact dermatitis (ICD) varies conspicuously. While electroplaters and solderers predominantly suffer from ACD (82% resp. 71%), in other occupational groups ICD is more common: mechanics (60%), locksmiths and automobile mechanics (59%) or metal-surface processors (53%). The type IV allergens differ widely depending on the occupational exposure. The most important allergen in solderers is colophony, in electroplaters nickel sulphate and potassium dichromate. There is a wide range of allergens in metal working fluids and it is mandatory to patch test patient‘s own working materials due to the fact that important allergens are not yet included in the screening series.

    Notes: Objectives:  Occupational skin diseases (OSDs) account for a large number of occupational diseases in Europe. Population-based epidemiological studies concerning certain occupations (e.g. Health care workers), however, are missing.Aim of our study was to analyse the reports of OSD in Health care workers (HCW) in the register of OSDs of Northern Bavaria and to assess the annual incidence in this occupational group in relationship to the total employed population in Northern Bavaria. Further, we investigated the spectrum of sensitizations with and without occupational relevance in this group.Methods:  A total of 5285 cases of OSD were assessed prospectively and registered from 1990–1999. Data of total employment were provided by the German Federal Employment office.Results:  A total of 3097 cases were confirmed as OSD in 24 occupational groups, of which 482 were confirmed in the group of HCW. The average annual incidence of OSD in this group accounted for 7.3 per 10,000 workers. In 1990 the incidences in this occupational group accounted for 11.4%, in 1999 for 5.0% per 10,000 workers with highest incidences in younger age groups. In the evaluated health care workers from the register of OSD in Northern Bavaria 54%(n = 260) had irritant and 51%(n = 244) had allergic contact dermatitis including 19%(n = 89) who suffered from both. Of the 482 HCW 13% had occupational relevant Type IV allergy to glutaraldehyde, 12% to thiurams, 6% to nickel (II) sulfate, 4% to formaldehyde or fragances, respectively, 2% to thimerosal, potassium (II) chloride, chloromethyl-isothiazolone and p-phenylendiamine (free base) each.Conclusions:  HCW belong to the occupational groups at exceedingly high risk for OSD. Higher frequencies of OSD occur in younger age groups. Irritant and allergic contact dermatitis are equally common causes of OSD in HCW. Sensitization to certain allergens (e.g. glutaraldehyde, thiurams and latex) are most often of occupational relevance, whereas others although frequently found (e.g. sensitization to nickel-II-sulfate, cobalt-II-chloride, fragance-mix) rarely are of occupational relevance.

    Notes: We identified risk factors for postoperative anxiety and quantified their effect on 712 adults between 18 and 60 years of age (ASA I–III physical status) undergoing elective surgery under general anaesthesia, neural blockade or both. The measuring instruments were a structured questionnaire, a pain visual analogue scale, the McGill Pain Questionnaire, the State-Trait Anxiety Inventory, the Montgomery–Äsberg Depression Rating Scale, a Self-Reporting Questionnaire-20, and a Self-Perception of Future Questionnaire. Multivariate conditional regression modelling taking into account the hierarchical relationship between risk factors revealed that postoperative anxiety was associated with ASA status III (OR = 1.48), history of smoking (1.62), moderate to intense postoperative pain (OR = 2.62) and high pain rating index (OR = 2.35), minor psychiatric disorders (OR = 1.87), pre-operative state-anxiety (OR = 2.65), and negative future perception (OR = 2.20). Neural block anaesthesia (OR = 0.72), systemic multimodal analgesia (OR = 0.62) and neuroaxial opioids with or without local anaesthesia (OR = 0.63) were found to be protective factors against postoperative anxiety.

    Notes: Abstract: The reaction γd↦π0 X has been measured with TAPS at MAMI in the energy range E γ = 140-300 MeV. Using the Glasgow tagging spectrometer a photon energy resolution of 0.8 MeV was achieved. The energy excitation functions of integral and differential total cross-sections show no structures of statistical significance 〉 2σ. Upper limits for the production of narrow isoscalar or isovector dibaryons with masses m? 2100 MeV/c2 were deduced. They are in the range 2-5 μb averaged over the 0.8 MeV energy resolution.

    Notes: Abstract Ion chromatographic separation coupled with ICP-MS was used to determine arsenic species in plant and soil extracts. A scheme for growth, harvesting, sample pre-treatment and analysis was developed for the arsenic species to enable determination. Preliminary results obtained with ten herb plants grown on arsenic-contaminated soil compared to non-contaminated soil show a heterogeneous pattern of accumulation rate, metabolization and detoxification mechanisms in monocots and dicots. Arsenite appears to be the major component in plants with good growth. Organic arsenic species were even detected at very low concentrations (〈 150 μg kg–1 (dry mass)).

    Notes: Abstract  The abundance and genomic organization of six simple sequence repeats, consisting of di-, tri-, and tetranucleotide sequence motifs, and a minisatellite repeat have been analyzed in different gymnosperms by Southern hybridization. Within the gymnosperm genomes investigated, the abundance and genomic organization of micro- and minisatellite repeats largely follows taxonomic groupings. We found that only particular simple sequence repeat motifs are amplified in gymnosperm genomes, while others such as (CAC)5 and (GACA)4 are present in only low copy numbers. The variation in abundance of simple sequence motifs reflects a similar situation to that found in angiosperms. Species of the two- and three-needle pine section Pinus are relatively conserved and can be distinguished from Pinus strobus which belongs to the five-needle pine section Strobus. The hybridization pattern of Picea species, bald cypress and gingko were different from the patterns detected in the Pinus species. Furthermore, sequences with homology to the plant telomeric repeat (TTTAGGG)n have been analyzed in the same set of gymnosperms. Telomere-like repeats are highly amplified within two- and three- needle pine genomes, such as slash pine (Pinus elliottii Engelm. var. elliottii), compared to P. strobus, Picea species, bald cypress and gingko. P. elliottii var. elliottii was used as a representative species to investigate the chromosomal organization of telomere-like sequences by fluorescence in situ hybridization (FISH). The telomere-like sequences are not restricted to the ends of chromosomes; they form large intercalary and pericentric blocks showing that they are a repeated component of the slash pine genome.Conifers have genomes larger than 20000 Mbp, and our results clearly demonstrate that repeats of low sequence complexity, such to (CA)8, (GA)8, (GGAT)4 and (GATA)4, and minisatellite- and telomere-like sequences represent a large fraction of the repetitive DNA of these species. The striking differences in abundance and genome organization of the various repeat motifs suggest that these repetitive sequences evolved differently in the gymnosperm genomes investigated.

    Notes: Abstract Microtechnology is regarded as one of the key technologies of the 21st century that will decisively influence nearly all fields of daily life. The demand for vocational education in this discipline is growing rapidly. This education must be a continuous life long learning process since microtechnology is characterised by frequent improvements of the fabrication processes and facilities. The use of Internet-resources offers new chances in teaching and training, especially for design, production or application of products from high aspect ratio micro-engineering technologies. The present paper reports on the development of a novel concept of interactive Internet-based training entities in the field of High Aspect Ratio Technologies. The training topics are dedicated towards innovative engineering technologies, particularly the LIGA technique, laser-based microtechnologies and microengineering related aspects of precision engineering. This training is addressed to graduate students, design engineers and executives mainly in small and medium sized enterprises. http://www-ttec.rs.uni-siegen.de
