A term analysis of the Fe III spectrum in the ultraviolet region enables the writers to predict Fe III lines which fall in the astronomically observable region. Several of them are present in B-type stars, both as absorption and as emission lines. [less ▲]Detailed reference viewed: 23 (3 ULg)

PURPOSE: The aim is to report our observations regarding the role of F-18 FDG PET in children's infectious processes. MATERIAL AND METHODS: A presentation is made of 3 neonatal infections unresponsive to treatment, 2 invasive infections in immunocompromised children, and 1 discitis in an immunocompetent child. PET or PET/CT was performed to address a specific question pertaining to the management of the diseases. Results were correlated with the clinical outcome. The impact on patient management is discussed. RESULTS: In 1 neonate, PET localized the infection in a bone which allowed surgical curettage. In another one, it localized the infection in recently renewed exogenous material and led to subsequent removal. It was negative in the third one, whose evolution was rapidly favorable. In the immunocompromised children, treatment of invasive infection was adapted according to the metabolic inflammatory activity of the disease. In a limping child with slight abnormalities on bone scintigraphy but major misleading involvement on MRI, PET/CT demonstrated hypermetabolism limited to a disc, thus avoiding further invasive procedures. CONCLUSIONS: Although not meant as a first choice examination, F-18 FDG PET should be considered in difficult cases of neonatal infection or in challenging diagnoses like discitis in the young child. It provides more accurate staging and treatment monitoring of the inflammatory process in invasive infections of immunocompromised children. [less ▲]Detailed reference viewed: 118 (4 ULg)

Purpose: The aim of this study was to assess rheumatoid arthritis (RA) synovitis with positron emission tomography (PET) and F-18-fluorodeoxyglucose (F-18-FDG) in comparison with dynamic magnetic resonance imaging (MRI) and ultrasonography (US). Methods: Sixteen knees in 16 patients with active RA were assessed with PET, MRI and US at baseline and 4 weeks after initiation of anti-TNF-alpha treatment. All studies were performed within 4 days. Visual and semi-quantitative (standardised uptake value, SUV) analyses of the synovial uptake of FDG were performed. The dynamic enhancement rate and the static enhancement were measured after i.v. gadolinium injection and the synovial thickness was measured in the medial, lateral patellar and suprapatellar recesses by US. Serum levels of C-reactive protein (CRP) and metalloproteinase-3 (MMP-3) were also measured. Results: PET was positive in 69% of knees while MRI and US were positive in 69% and 75%. Positivity on one imaging technique was strongly associated with positivity on the other two. PET-positive knees exhibited significantly higher SUVs, higher MRI parameters and greater synovial thickness compared with PET-negative knees, whereas serum CRP and MMP-3 levels were not significantly different. SUVs were significantly correlated with all MRI parameters, with synovial thickness and with serum CRP and MMP-3 levels at baseline. Changes in SUVs after 4 weeks were also correlated with changes in MRI parameters and in serum CRP and MMP-3 levels, but not with changes in synovial thickness. Conclusion: F-18-FDG PET is a unique imaging technique for assessing the metabolic activity of synovitis. The PET findings are correlated with MRI and US assessments of the pannus in RA, as well as with the classical serum parameter of inflammation, CRP, and the synovium-derived parameter, serum MMP-3. Further studies are warranted to establish the place of metabolic imaging of synovitis in RA. [less ▲]Detailed reference viewed: 128 (16 ULg)

Purpose: The aim of this study was to retrospectively evaluate the performance of positron emission tomography (PET) with F-18-fluorodeoxyglucose (F-18-FDG) in children with lymphomas, at various stages of their disease. Methods: Twenty-eight children (mean age 12.5 years, 14 girls, 14 boys) with Hodgkin's disease (HD, n=17) or non-Hodgkin's lymphoma (NHL, n= 11) were evaluated. Patients were investigated at initial staging (n=19), early in the course of treatment (n=19), at the end of treatment (n=16) and during long-term follow-up (n=19). A total of 113 whole-body PET studies were performed on dedicated scanners. PET results were compared with the results of conventional methods (CMs) such as physical examination, laboratory studies, chest X-rays, computed tomography, magnetic resonance imaging, ultrasonography and bone scan when available. Results: At initial evaluation (group 1), PET changed the disease stage and treatment in 10.5% of the cases. In early evaluation of the response to treatment (group 2), PET failed to predict two relapses and one incomplete response to treatment. In this group, however, PET did not show any false positive results. There were only 4/75 false positive results for PET among patients studied at the end of treatment (group 3, specificity 94%) or during the systematic follow-up (group 4, specificity 95%), as compared with 27/75 for CMs (specificity 54% and 66%, respectively). Conclusion: F-18-FDG-PET is a useful tool for evaluating children with lymphomas. Large prospective studies are needed to appreciate its real impact on patient management.

The LARSP (Language Assessment, Remediation and Screening Procedure) (Crystal et al., 1976) is a linguistic profile commonly used by researchers and clinicians to carry out detailed analyses of the grammar and morphology of children’s spontaneous language samples. This paper discusses the methods used to adapt the profile from English to French using a large corpus of child language in order to accurately assign morphosyntactic structures to age-based stages.

This paper presents the adaptation of the LARSP (Language Assessment, Remediation and Screening Procedure) (Crystal et al., 1976) from English into French based on the analysis of a corpus of French speaking children ranging between the ages of 18 months and 5 years. Included is a description of particularities of French morphosyntax and the ensuing adaptations that are reflected on the new French LARSP (F-LARSP) chart. The LARSP is a linguistic profile commonly used by researchers and clinicians to carry out “comprehensive and consistent linguistic analysis” (Ball, 1999); more specifically a detailed analysis of the grammar and morphology of children’s spontaneous language samples. The profile was developed in a manner that allows the user to clearly see the child’s grammatical strengths and weaknesses in relation to their chronological age. This is made possible by the notion that the order in which syntactic structures are acquired is relatively stable, at least until the approximate age of 5. Correlation of a child’s morphosyntactic production to their age provides the therapist with vital information regarding an array of areas including the possible diagnosis of language impairment, remediation planning, and measuring treatment efficacy carried out since the last profiling session. The tool is therefore useful for professionals working with children who are suspected of or who have been diagnosed with having forms of language difficulties such as Specific Language Impairment (SLI) where morphology and syntax are commonly affected. The utility of the LARSP, originally designed for Anglophone use, has led to its adaptation to several other languages. Those which have been published for an international audience include Welsh (1988), Dutch (1987), Irish (1990) and Persian (1998). [less ▲]Detailed reference viewed: 315 (9 ULg)
