Abstract

De geregistreerde criminaliteit en het ervaren slachtofferschap neemt niet alleen in Nederland, maar ook internationaal, al jaren af. Naast de mogelijkheid dat de criminaliteit in werkelijkheid daalt, wordt ook rekening gehouden met de mogelijkheid dat de waargenomen daling het gevolg is van een verandering van de aard van criminaliteit en dat er (wellicht) een verschuiving plaatsvindt van criminaliteit die geregistreerd wordt naar criminaliteit die nu niet (standaard) geregistreerd wordt of niet door slachtofferenquêtes gemeten wordt. Hiermee wordt geduid op het probleem omtrent het dark number van de criminaliteit. Met de niet-geregistreerde criminaliteit wordt bedoeld, het onbekende deel van de criminaliteit die niet geregistreerd wordt in de politiestatistieken. Ongeacht welke meetinstrumenten er nu gebruikt worden voor het meten van (de ontwikkeling) van criminaliteit, een onbekend deel van de criminaliteit blijft buiten zicht. Hierdoor kan er eigenlijk geen beoordeling gegeven worden van de stand van zaken van dé criminaliteit. Zowel maatschappelijk, wetenschappelijk als beleidsmatig staat het thema van het dark number en het inzicht krijgen in de niet-geregistreerde criminaliteit uitdrukkelijk in de belangstelling. Dit onderzoek bestaat uit twee delen: Deelproject 2830A betreft de omvang en aard van de niet geregistreerde criminaliteit, zijnde een meer generieke wetenschappelijk/methodologische inleiding: welk deel van criminaliteit meten we reeds, welke alternatieven of nieuwe kansrijke initiatieven zijn nu gaande. Dit deelproject 2830B betreft de vraag met welke (nieuwe) methoden, meetinstrumenten en technieken de niet-geregistreerde cybercriminaliteit (zowel cybercrime als gedigitaliseerde criminaliteit), horizontale fraude en georganiseerde criminaliteit gemeten kan worden.

Abstract

Typical echodense haemangiomas of the liver can easily be identified by B-scan ultrasound. Atypical or giant haemangiomas of the liver, however, need to be differentiated from secondary tumours or primary liver carcinomas and cholangiocarcinomas. Until recently, computed tomography or magnetic resonance tomography were required to confirm the diagnosis, and not so rarely even a fairly risky fine-needle puncture had to be performed. Contrast media-assisted sonography, in general, offers the same scope of differentiating liver tumours as the radiographic tomography methods. Contrast media-assisted sonography is not yet widely available and has not been sufficiently evaluated. One important limitation is thought to be the lack of echo depth. We demonstrate the diagnostic value of this method in the case of a liver haemangioma measuring more than 20 cm in diameter. The resulting clinical questions are being discussed.

Abstract

Summary The aim of this study was to evaluate whether scintimammography using 99Tcm-sestamibi or contrast-enhanced magnetic resonance imaging (MRI) can improve the specificity of mammography for the differentiation of benign and malignant breast microcalcification. From 156 consecutive patients studied with SMM, 44 patients with microcalcification on mammograms were selected for this study. Forty patients in this group also had contrast-enhanced MRI of the breast. The intensity and patterns of sestamibi uptake for scintimammography and contrast enhancement for MRI were visually determined and graded on a 5-point scale for malignancy. The results of both techniques were compared and correlated with final histopathologic diagnoses. The sensitivity and specificity of scintimammography were 63% and 85% respectively, if only those cases classified as probable or definite malignancy were considered positive. If indeterminate findings were also considered positive, the sensitivity and specificity of scintimammography were 79% and 80% respectively. Using the latter classification for MRI revealed a comparable sensitivity of 82% but a markedly lower specificity of 56%. Excluding indeterminate findings from the group of positive MRI diagnoses resulted in a specificity of 94% and a sensitivity of 64%. In conclusion, scintimammography of the breast had a comparable sensitivity but a higher specificity than MRI. The sensitivity of both techniques, however, is probably too low for routine use in the evaluation of microcalcification detected by mammography.

Abstract

RIVM rapport:Abstract niet beschikbaar, This report describes a study that has tried to understand the coupling between the main driving forces of land use change and the emission of greenhouse gasses in the context of coupled land surface climate models. Studies related to investigating the main driving forces of land use change in Europe and assessing the budgets of the main greenhouse gasses in Europe were combined with sensitivity studies of land use change and climate at regional and global scale. These were linked to an integrated assessment model and selected economic analysis. Full integration of the parallel studies proved difficult in the timeframe of the project. The individual studies yield insight into the main driving forces of land use in Europe, the size of the biospheric GHG budget, the sensitivity of regional and global climate to land use change, and the global effects of trade in GHG mitigation control.
