    Notes: Abstract A method for the separation of structure functions in (e, e′ p) experiments is proposed, which is an extension of the traditional Rosenbluth-type techniques of [1,2]. In our approach, we use a very flexible Ansatz to describe the structure functions within an extended kinematical regionG and determine its free parameters with a x2 minimization. The procedure is tested by pseudo data (12C(e, e′p)11Bg.s.) in the quasi-free region.

    Description / Table of Contents: Abstract Hallervorden-Spatz disease (HSD), a rare extrapyramidal motor illness, is usually only confirmed after death. In vivo diagnosis has relied hitherto on the combination of typical magnetic resonance imaging (MRI) findings (the “eye of the tiger” sign) and heterogeneous clinical symptoms of movement disorder which have been regarded as almost pathognomonic. We report on the diagnostic contribution of 123J-β-CIT single photon emission computed tomography (SPECT) and 123J-IBZM SPECT in akinetic-rigid Parkinson's syndrome occurring in a case of HSD. In contrast to Parkinson's disease and multisystem atrophies, the results of both tests were normal. This constellation of findings shows that the degeneration lies primarily outside the nigrostriatal system, supporting arguments for the nosologic distinction of HSD from other extrapyramidal illnesses.
    Notes: Zusammenfassung Die Diagnose der Hallervorden-Spatz-Krankheit (HSD), einer seltenen extrapyramidal-motorischen Erkrankung, konnte gewöhnlich erst postmortal gesichert werden. Bislang galt der typische MRT-Befund mit dem “Tigerauge-Zeichen” in Kombination mit der heterogen klinischen Symptomatik von Bewegungsstörungen als nahezu pathognomonisch und diente zur Diagnosestellung zu Lebzeiten. In der vorliegenden Kasuistik soll der diagnostische Beitrag von 123J-β-CIT und 123J-IBZM-SPECT bei einem akinetisch-rigiden Parkinsonsyndrom im Rahmen einer HSD dargestellt werden. Für beide Untersuchungen wurden im Gegensatz zum M. Parkinson und Multisystematrophien Normalbefunde gefunden. Diese Befundkonstellation zeigt einerseits, dass die Degeneration primär außerhalb des nigrostriatalen Systems liegt, und andererseits unterstützt sie die Diskussion der nosologischen Abgrenzung der HSD von anderen extrapyramidalen Erkrankungen.

    Notes: Abstract The objective of the study was to translate and adapt the SF-36 Health Survey for use in Tanzania and to test the psychometric properties of the Kiswahili SF-36. A cross-sectional study was conducted as part of a household survey of a representative sample of the adult population of Dar es Salaam, Tanzania. The IQOLA method of forward and backward translation was used to translate the SF-36 into Kiswahili. The translated questionnaire was administered by trained interviewers to 3,802 adults (50% women, mean (SD) age 31 (13) years, 50% married and 60% with primary education). Data quality and psychometric assumptions underlying the scoring of the eight SF-36 scales were evaluated for the entire sample and separately for the least educated subgroup (n=402), using multitrait scaling analysis. Forward and backward translation procedures resulted in a Kiswahili SF-36 that was considered conceptually equivalent to the US English SF-36. Data quality was excellent: only 1.2% of respondents were excluded because they answered less than half of the items for one or more scales; ninety percent of respondents answered mutually exclusive items consistently. Median item–scale correlations across the eight scales ranged from 0.47 to 0.81 for the entire sample. Median scaling success rates were 100% (range 87.5–100.0). The median internal consistency reliability of the eight scales for the entire sample was 0.81 (range 0.70–0.92). Floor effects were low and ceiling effects were high on five of the eight scales. Results for n=402 people without formal education did not differ substantially from those of the entire sample. The results of data quality and psychometric tests support the scoring of the eight scales using standard scoring algorithms. The Kiswahili translation of the SF-36 may be useful in estimating the health of people in Dar es Salaam. Evidence for the validity of the SF-36 for use in Tanzania needs to be accumulated.

    Notes: Abstract The International Quality of Life Assesment (IQOLA) Project is a 4-year project to translate and adapt the widely used MOS SF-36 Health Survey Questionnaire in up to 15 countries and validate, norm, and document the new translations as required for their use in international studies of health outcomes. In addition to the eight-scale SF-36 health profile, the project will also validate psychometrically based physical and mental health summary scores, as well as health utility indexes incorporating SF-36 scales for use in cost-utility studies.
