Airborne pollen grains in Bursa, Turkey, 1999-2000

86%
In this study, pollen grains were sampled by using a Lanzoni trap (Lanzoni VPPS 2000) in atmosphere of Bursa in 1999 and 2000. During two years, a total of 13,991 pollen grains/m3 which belonged to 59 taxa and unidentified pollen grains were recorded. A total of 7,768 pollen grains were identified in 1999 and a total of 6,223 in 2000. From these taxa, 36 belong to arboreal and 23 taxa to non-arboreal plants. Total pollen grains consist of 78.61% arboreal, 20.37% non-arboreal plants and 1.03% unidentified pollen grains. In the region investigated, Pinus sp., Olea sp., Platanus sp., Gramineae, Cupressaceae/Taxaceae, Quercus sp., Acer sp., Morus sp. Xanthium sp., Castanea sp., Chenopodiaceae/Amaranthaceae, Corylus sp., Artemisia sp., Urtica sp. and Fraxinus sp. were responsible for the greatest amounts of pollen. During the study period the pollen concentration reached its highest level in April.
The aim of the research: discovering the relation between the participation of elderly people in the occupational therapy and their Health-Related Quality of Life. Research material and methods: research was carried out in the public social centres offering the occupational therapy devoted to the elderly people. 95 people whose average age was 72,1 years (58 women and 37 men) were examined. The examinees were divided into two groups: the participants and those who were not involved in the occupational therapy. The method of direct interview using EQ-5D-3L questionnaire - a standard instrument for measuring Health-Related Quality of Life of the elderly people was applied. The results: Seniors involved in occupational therapy reported better HRQL. Difficulties with mobility (<0,05), pain/discomfort (<0,001) and anxiety (<0,001) were substantially more visible around people who did not take part in the occupational therapy. The average self-reported health was better among the occupational therapy participants (<0,001) in comparison with the other elderly people who were not engaged in those activities (76,5 vs. 43,6 respectively). Conclusions: participation in the occupational therapy has a positive effect on the functioning of the elderly people in every sphere of their life: physical, mental and social one. Involvement in the occupations resulted in the improved perception of the Health-Related Quality of Life. Occupational therapy turned out to be an inexpensive and effective method that exerts a positive impact on maintenance of physical and intellectual abilities, social inclusion as well as physical rehabilitation of seniors.

Airborne pollen calendar of Izmir - Turkey

72%
A qualitative and quantitative evaluation of pollen concentration in the atmosphere of Izmir metropolitan area is presented. Investigations were undertaken from November 1998 to October 1999 using gravimetric method. The aeroplynological studies revealed that at lower level (1.60 m) pollen from 29 woody and 30 herbaceous taxa were determined, whereas at higher level (20 m) pollen from 26 woody and 24 herbaceous taxa were recorded. At lower level, dominating woody species were Pinus, Quercus, Oleaceae, Cupressaceae/Taxaceae; herbaceous species were Gramineae, Chenopodiaceae/ Amaranthaceae, Cruciferae and Plantago. At higher level, Pinus, Cupressaceae/Taxaceae, Gramineae, Chenopodiaceae/Amaranthaceae, Cruciferae and Plantago pollens were dominant. Morus, Oleaceae, Quercus, Chenopodiaceae/Amaranthaceae, Gramineae and Plantago showed highest concentration and their allergic degree was very high. Annual pollen calendar of the area is shown.

Empowerment in farmers' occupational health services

72%
This study attempted to develop farmers' health and farmers occupational health services (FOHS) by examining the effects and feasibility of empowered farmers' teams on walk-through surveys of Finnish dairy farms. FOHS personnel of the health centre in three municipalities selected three farmer teams for the intervention group. Each team consisted of three or four couples. The selected comparison group resembled the intervention group. The number of the farms was 31 in the intervention group and 33 in the comparison group. Before and after the intervention each subject responded to questionnaires. The initial walk-through survey was carried out in 1998-1999, and the follow-up took place in 2000-2001. During the follow-up the FOHS personnel identified the changes made after the initial surveys on the farms. The farmers and FOHS personnel also underwent a thematic interview. Altogether 217 changes were made, half of them to improve ergonomics, and 87 of the 217 were extensive. The empowered farmer groups produced more changes in the work environment. The use of empowered farmer groups is feasible in walk-through surveys, and the approach can be easily learned. Empowered groups are also a challenge for FOHS personnel, and they enrich the work of these workers. The farmers want more varied measures for work-site health promotion, and, particularly, they feel that an occupational health physician should be present on walk-through surveys.
Employing the volumetric method by use of a Hirst sampler, a total of 71,286 pollen grains, as many as 94.20% of them allergenic, were recorded in the air samples from the city of Zagreb during the 2002 pollen season. Among identified pollen of 35 plant species/genera/families, 23 were allergenic: Taxus/Juniperus, Alnus sp., Fraxinus sp., Betula sp., Corylus sp., Poaceae, Urticaceae, Artemisia sp., Ambrosia sp., Carpinus sp., Castanea sp., Chenopodiaceae, Salix sp., Populus sp., Ulmus sp., Juglans sp., Quercus sp., Platanus sp., Fagus sp., Plantago sp., Pinus sp., Picea sp. and Abies sp. The pollen of these plants also cause the majority of pollinosis in Europe. Study results and the pollen calendar designed for the 2002 pollen season for the City of Zagreb provide useful data for allergologists to reach an accurate diagnosis. The calendar also provides timely information on airborne pollen types and air concentrations for individuals with pollen hypersensitivity, thus allowing them to adjust their daily activities so as to minimize their contact with allergens and improve their quality of life both at home and at work.
B(1→3)-glucans were extracted from wood dust samples taken during the summer of 1997 at four British Columbia sawmills. Personal dust samples were collected using a GSP-sampler for inhalable dust and the sampling strategy targeted all production and maintenance jobs at least once at each mill. Potential exposure determinants data were documented concurrently, including weather conditions, log storage methods, wood conditions, species, production level, jobs and tasks. B(1→3)-glucans were measured by enzyme inhibition immunoassay (EIA). A total of 223 personal B(1→3)-glucan samples were analyzed. 45.7% were below the limit of detection (LOD). Geometric mean concentration ranged from 3.5 to 18.9 µg/m3 across the four mills. The highest levels were measured at the Interior mills, particularly in the log processing and sawmill areas. Multivariate regression models indicated that land-based log storage, clean-up jobs, high wood dust concentration, lumber yard department and the interaction between land-based log storage method and log processing department were associated with increased B(1→3)-glucan concentration.
The aim of the NetWoRM Project is the development, evaluation and implementation of a case-based e-learning tool for occupational medicine to increase the knowledge in clinical aspects of occupational medicine. To date, 19 e-learning cases have been developed. Cases were validated by 2 experts and user evaluated. Results of the user evaluation at 3 German Medical Schools are presented. Of 557 medical students registered for the online course 377 answered the online evaluation form (68%). Depending on the case, the median time spent on a case ranged from 25–43 minutes. Students enjoyed working with the cases and asked to replace more seminars by case-based e-learning. The level of knowledge required to work on the cases was rated high. This was supported by the fact that on median only 47–71% of the questions were answered correctly. Cases focusing on occupational health problems such as needle stick injuries were rated highest with respect to fun, importance for future career and the overall score. Students enjoy working on e-learning cases as an add-on to traditional teaching. Because of the high international interest the NetWoRM project is currently shared on an international base.
Microbiological control of water quality in dental units waterlines is extremely significant for patients and dental personnel. Based on the latest scientific literature, ways of reducing microbial contamination of dental treatment water and biofilm elimination are presented. The use of disinfectants, drying, and flushing are described. Further research to evaluate effectiveness, convenience on a day-to-day basis and economic aspects of various methods is required.
The aim of the present study was to determine the seasonal abundance of ticks, Ixodes ricinus and their infection frequency with spirochetes, Borrelia burgdorferi in wooded areas of the vicinity of the city of Szczecin during 2000-2001. The ticks were collected from April to October. Presence of Borrelia burgdorferi sensu lato was detected with the method of indirect immunofluorescence (IFA). The results showed differences in seasonal activity of ticks within the years of the study. In the year 2000 a single peak of their increased activity was noted, while in the year 2001 no significant changes in the population of Ixodes ricinus were recorded. Borrelia burgdorferi s. l. was detected in 2000 and 2001 in 11.6% and 9.6% of the specimens captured, respectively, which constituted a statistically significant difference. The highest level of infection of Ixodes ricinus in 2000 was observed in April (13.2%), while in 2001 - in July (12.7%). The differences in the prevalence value between respective months of both years were not statistically significant. The results of the present study indicate a high risk factor of acquiring Lyme borreliosis by humans and animals in wooded areas of the Szczecin vicinity.
In 1997-1998, annual variations in the concentration of pollen in the atmosphere of Lublin, Poland, were analysed by the volumetric and gravimetric methods. To determine the concentration of pollen, a volumetric VST-trap was used, whereas for pollen fall - a gravimetric Durham trap. The following taxa were chosen for pollen analysis: Alnus, Corylus, Populus, Betula, Poaceae, Rumex, Plantago, Urtica, Chenopodiaceae and Artemisia. It was found that the length of pollen season, as well as pollen count increase and decrease tendencies determined by the two methods, were similar. Maximum concentrations of pollen grains occurred on the same dates for arboreous plants, Artemisia and Poaceae in 1997. In the case of other herbal plants, the maximum dates might be different, yet abundant occurrence of pollen grains was registered at the same time.
