Behaviour style and interaction between seven children with multiple disabilities and their caregivers.
INTRODUCTION: Recent studies show that the existing interaction patterns of children with multiple disabilities should be taken into consideration when planning communication interventions. For children with disabilities, it is especially important that the partner in interaction is sensitive and well aware of the importance of a qualitatively successful interaction. Wilder (unpublished report) found that the behaviour style of 30 children with multiple disabilities was more related to the caregiver-perceived interaction than the communicative skills and functional abilities of the children. This study inductively explored the caregivers' perceptions of interaction within seven caregiver-child dyads. The research questions were: How do the caregivers perceive the interaction? How do the caregivers perceive the children's behaviour style to be related to the interaction with the caregivers? METHOD: The children were selected individually from the participants in Wilder (unpublished report) depending upon the responses the caregivers had given about the children's self-regulation and reactivity in the Carolina Record of Individual Behaviour questionnaire. The study was undertaken by means of home visits where the caregivers participated in an interview asking about their strategies for interaction, how they perceived the roles of the children and their own roles in interaction, the caregivers' opinion of what an interaction constituted of and the caregivers' aims and aspiration for interaction. The data analysis was performed by meaning concentration and categorization through a pendulum between the parts and the entirety of the interviews. In this way, hermeneutics and thematic analysis were both being practised. RESULTS: The results of the interviews are presented as a model with categorizations as a network. The categorizations reflect the system of themes that permeate how the caregivers perceived interaction in the dyad. The themes are: sharing of experience, successful interaction, role of the child, role of the caregiver, interaction methods, obstacles and facilitators and aims and aspirations. DISCUSSION: The caregivers perceived their own role in interaction to be of a sensitive leading kind. The caregivers lead the interaction by using their knowledge about the children's usual way of interacting, the children's behaviour styles, functional abilities, the children's current mood and situation as well as the whole context. They monitored the interaction such that, throughout an interaction sequence, the caregivers always tried to optimize the interaction between the parties in the dyad. The behaviour style was a background factor that the caregivers had knowledge of and scanned in their everyday turn taking. Although there were differences in the children's behaviour styles, the caregivers discussed the same themes in the interviews. The behaviour style became a facilitator for the whole interaction, forced the interaction in certain directions and made the interaction more complete with turn taking of different kinds from both parties. The findings show that it is imperative to see caregivers as experts on their children and to make them assertive in this in relation to professionals. Furthermore, as a successful interaction can boost the development of children, it is essential to direct interventions to the everyday interaction in caregiver-child dyads.

Mutually exclusive distribution of IS1548 and GBSi1, an active group II intron identified in human isolates of group B streptococci.
The present study shows that active, self-splicing group II intron GBSi1 is located downstream of the C5a-peptidase gene, scpB, in some group B streptococcus (GBS) isolates that lack insertion sequence IS1548. IS1548 was previously reported to be often present at the scpB locus in GBS isolated in association with endocarditis. Since none of 67 GBS isolates examined, 40 of which were of serotype III, harbored both IS1548 and GBSi1, these two elements are suggested to be markers for different genetic lineages in GBS serotype III. The DNA region downstream of scpB in GBS isolates harboring either GBSi1, IS1548, or none of these mobile elements was found to encode the laminin binding protein, Lmb, which shows sequence similarities to a family of streptococcal adhesins. IS1548 is inserted 9 bp upstream of the putative promoter for lmb, while the insertion site for GBSi1 is located 88 bp further upstream. Sequences highly similar to GBSi1 exist also in Streptococcus pneumoniae. An inverted repeat sequence, with features typical of transcription terminators, was identified immediately upstream of the insertion site for the group II intron both in the GBS and S. pneumoniae sequences. This motif is suggested to constitute a target for the GBS intron as well as for rather closely related introns in Bacillus halodurans, Pseudomonas alcaligenes, and Pseudomonas putida. When transcripts containing the GBSi1 intron were incubated at high concentrations of ammonium and magnesium, a major product with the expected length and sequence for the ligated exons was generated. Unlike, however, all members of group II investigated so far, the excised intron was in linear, rather than in a branched (lariat), form.

Identification of a novel insertion element, IS1548, in group B streptococci, predominantly in strains causing endocarditis.
Hyaluronidase has been postulated to be a virulence factor in group B streptococci (GBS). No hyaluronidase activity was found in 15 of 50 GBS isolates from adults studied. Most of these hyaluronidase-negative strains belonged to serotype III. In strains lacking hyaluronidase activity, an insertion of 1317 nucleotides was found in the hyaluronidase gene. The fragment was cloned and sequenced and found to have characteristics of a novel insertion sequence, designated IS1548. As well as in GBS serotype III, this sequence was found in 3 of 6 serotype II isolates and in all 10 group A streptococcal strains (GAS) tested. Homologies were found with repeated sequences in Streptococcus pneumoniae and with H repeats in Escherichia coli. All GBS strains harboring IS1548 and some GAS strains had one copy of IS1548 located downstream of the C5a peptidase gene. IS1548 was present in 9 of 13 GBS isolates from blood in endocarditis patients and in 3 of 22 vaginally colonizing strains.

Leuconostoc spp. septicaemia in a child with short bowel syndrome.
Septicaemia caused by the vancomycin-resistant Gram-positive bacteria Leuconostoc spp. is uncommon. We report a case of Leuconostoc spp. septicaemia in a child with short bowel syndrome fed through a central venous catheter and a gastrostomy. Leuconostoc spp. were isolated from several blood cultures. Despite several courses of antibiotics the fever continued and her condition deteriorated. After removal of the thrombotized central venous catheter her condition improved. Leuconostoc spp. was isolated from the thrombotic masses.

CD4 lymphopenia in a patient with cryptococcal osteomyelitis.
Cryptococcus neoformans is a rarely reported cause of osteomyelitis. In most cases, no obvious underlying condition is found. Immunological laboratory data, however, are not generally available. In the present case of cryptococcal osteomyelitis, idiopathic CD4 lymphopenia was detected. This immunodeficiency is found in cases of disseminated cryptococcosis by chance. Possibly, it may be one so far unrecognized underlying condition in cryptococcal osteomyelitis.

Pivmecillinam in treatment of Staphylococcus saprophyticus urinary tract infections.
In a non-randomised trial 15 women with Staphylococcus saprophyticus bacteriuria were treated with pivmecillinam 200 mg t.i.d. for 1 week. At follow-up 2-4 weeks post treatment only 11 patients were cured. As a complement to the study the occurrence of Staph. saprophyticus bacteriuria was analysed according to age, sex and season. Mecillinam MIC's and viability curves of Staph. saprophyticus were investigated. It is concluded that mecillinam should only be used to treat urinary tract infections caused by bacteria sensitive in vitro.

Parent-child interaction: a comparison of parents' perceptions in three groups.
PURPOSE: To evaluate a children's version of the ICF that takes children's dependency on their parents and a developmental perspective into consideration. METHOD: This study explored how 91 parents perceived child participation in terms of parent/child immediate interaction, and desires for ideal interaction in relation to body impairments and activity limitations. Similarities and differences were investigated in three matched groups of families through questionnaires. Group 1 consisted of parents of children with profound multiple disabilities, Group 2 was developmentally matched and Group 3 was matched according to chronological age. RESULTS: The children with profound multiple disabilities expressed the same amount of emotions as the other groups, but they had difficulties expressing more complex emotions. Parents perceived the children's behaviour styles in a similar way in the three groups. There were significant differences in how the immediate interaction was perceived with parents to children of Group 1 perceiving difficulties in maintaining joint attention and directing attention. CONCLUSIONS: The results suggest that parental perceptions of the interaction with their children with profound multiple disabilities in the immediate setting to a certain extent are related to the body impairments of the children but not strongly to communicative skills /activity limitations. Thus, to focus communication intervention on participation and interaction, assessment and questions to parents have to be focused directly on these issues.
