Variability in Skin Exposure in Machine Operators Exposed to Cutting Fluids
1998
Ingår i: Scandinavian Journal of Work, Environment and Health. - : Scandinavian Journal of Work, Environment and Health. - 0355-3140 .- 1795-990X. ; 24:2, s. 125 - 129
Tidskriftsartikel (refereegranskat) abstract
Objective. This study describes a new technique for measuring skin exposure to cutting fluids and evaluates the variability of skin exposure among machine operators performing cyclic (repetitive) work. Methods. The technique is based on video recording and subsequent analysis of the videotape by means of computer-synchronized video equipment. The time intervals at which the machine operator's hand was exposed to fluid were registered, and the total wet time of the skin was calculated by assuming different evaporation times for the fluid. The exposure of twelve operators with different work methods was analyzed in six different workshops, which included a range of machine types, from highly automated metal cutting machines (ie, actual cutting and chip removal machines) requiring operator supervision to conventional metal cutting machines, where the operator was required to maneuver the machine and manually exchange products. Results; the relative wet time varied between 0% and 100%. A significant association between short cycle time and high relative wet time was noted. However, there was no relationship between the degree of automatization of the metal cutting machines and wet time. Conclusions. The study shows that skin exposure to cutting fluids can vary considerably between machine operators involved in manufacturing processes using different types of metal cutting machines. The machine type was not associated with dermal wetness. The technique appears to give objective information about dermal wetness. A comment: This publication is a result of a cooperation between the authors at Chalmers University of Technology and Gothenburg University, i.e. between the Department of Transportation and the Department of Occupational Health and the Department of Sociology.

Can severe language disorders be identified before age 3;6?
1996
Ingår i: Logopedics Phoniatrics Vocology. - : Informa UK Limited. - 1401-5439 .- 1651-2022. ; 21:1, s. 37-42
Tidskriftsartikel (refereegranskat) abstract
A new classification system indicating type and severity of language disorder was applied by five speech pathologists. They independently interpreted information from the initial language assessment of 39 children with developmental language disorder (DLD), who had been assessed by one of the present authors before age 3;6. Information about planned intervention was also collected. The children were reassessed 18 months later. The amount of language therapy the children had received was calculated and related to the type and severity of the language disorder. Our results indicate that the DLD children, who initially had general language problems performed worse on reassessment than children with expressive problems. More extensive intervention programmes were planned for the children with general DLD. According to follow-up data they had, however, not received more therapy than children with more restricted disorders.

Grammatical Characteristics Of Swedish Children With Sli
1995
Ingår i: Journal of Speech and Hearing Research. - 0022-4685. ; 38:3, s. 589-598
Tidskriftsartikel (refereegranskat) abstract
Spontaneous speech samples from 10 Swedish children were collected and analyzed grammatically. The subjects consisted of 5 children with SLI and 5 MLU matched controls with normal grammatical development. The children with SLI differed significantly from the controls in their more restricted usage of word order patterns and in number of grammatical errors. As in studies on English-speaking children with SLI, the Swedish children with SLI had a large number of omissions of grammatical morphemes. Verb-related errors were more common than noun-related errors. Contrary to reports on children with SLI acquiring other languages, however, word order errors were also very common in the Swedish children with SLI. A restricted usage of word order patterns in combination with errors of word order indicates that not only morphological deficits but also syntactic difficulties can be found in children with SLI relative to MLU controls, depending on the target language. The findings show the importance of cross-linguistic comparisons of children with SLI.

Patterns of verb usage in Swedish children with SLI: an application of recent theories
1997
Ingår i: First Language. - 0142-7237. ; , s. 195-217
Tidskriftsartikel (refereegranskat) abstract
Data from several languages, including Swedish, have shown that children with specific language impairment (SLI) have particular difficulties with verb morphology. In the present study, the verb morphology of six Swedish children with SLI was further explored in longitudinal and cross-sectional data. It was found that the children with SLI had significant problems with the use of auxiliary and modals, compared with younger MLU-matched controls. Although the children with SLI omit auxiliary and modals less frequently with increasing age, their levels of omission are not compatible with their MLU levels. The results are discussed with reference to recent accounts of the underlying nature of SLI.

Specific Language Impairment in Swedish: Grammar and Interaction
1998
Doktorsavhandling (övrigt vetenskapligt/konstnärligt) abstract
The main purpose of this work was to explore grammar in Swedish children with Specific Language Impairment (SLI), that is children with impaired language development in the presence of normal hearing and otherwise normal development. In four differents studies, spontaneous data from six children with SLI were analysed and compared with data from either younger children with phonological impairment but normal grammar (PI), or from younger controls with typical development. The children with SLI were matched to their controls on the basis of mean length of utterance (MLU). One of the studies also includes longitudinal data. A fifth study includes experimental data from 10 children with SLI and 10 younger language matched controls. The results showed that in particular word order, verb forms requiring an auxiliary or a modal, and subordination were structures where the Swedish children with SLI differed from their controls. The children with SLI were further found to have a higher amount of hesitation phenomena than children with PI. These two groups also differed with respect to qualitative aspects of their maze behaviour. The conversational partner was not found to influence structural aspects of the language production of children with SLI or PI. The conversational partner did, however, influence the interactive behavior and the productivity of the children. Clinically, the pinpointing of vulnerable structures have important implications for the assessment of children with language impairment in Sweden. The analysis of the influence of the conversational partner can have implications for therapy, if further developed. The results point to the importance of investigating SLI in different languages.

Evaluation of human seroreactivity to Bartonella species in Sweden
1999
Ingår i: Journal of Clinical Microbiology. - 0095-1137 .- 1098-660X. ; 37:5, s. 1381-1384
Tidskriftsartikel (refereegranskat) abstract
Among the species that compose the expanding genus Bartonella, thus far only B. henselae and B. quintana have reportedly been isolated from humans in Europe. To evaluate the prevalence of Bartonella infection in Sweden,we conducted a retrospective serological examination of 126 human serum samples. These samples were analyzed for antibodies to B. henselae, B. quintana, and B. elizabethae, Serum samples from 100 blood donors, who spanned the ages of 20 to 60 and had no apparent clinical signs of illness, were also studied as a control group. An immunoglobulin G indirect fluorescence antibody assay revealed 4 and 8.3% Bartonella positivity rates for the blood donor and patient group, respectively, when a cutoff titer of greater than or equal to 64 was chosen. Among the blood donors, four were seropositive to B, elizabethae; one of these also had concordant positive titer to B. henselae, In the patient group, 14 serum samples were positive against Bartonella spp, These serum specimens represented nine patients. In three of these seropositive patients, paired serum samples displayed a fourfold increase in antibody titer to at least one of the three antigens, These three patients are discussed. In this report we also present a case study of a 60-year-old Swedish male with fatal myocarditis, Postmortem serological analysis revealed a high titer against B. elizabethae, PCR and nucleotide sequencing of the myocardial tissue from this patient, and of Liver tissue from one of the other three patients, showed sequences similar to B. quintana, The age, geographical origin, animal contacts, and serological response pattern to the different Bartonella antigens differed among the four patients. This study substantiates the presence of Bartonella spp, in Sweden, documents the seroreactivity to three Bartonella antigens in Swedish patients, and reports the first two cases of B. quintana-like infections in Sweden.
