Amebic liver abscess: diagnosis and treatment evaluation with MR imaging

Magnetic resonance images were obtained before and after treatment in 17 patients with 29 amebic liver abscesses. Pretreatment T1-weighted images showed a sharply circumscribed, heterogeneous, low-signal-intensity mass, devoid of normal hepatic tissue and corresponding to the abscess cavity as measured sonographically. T2-weighted images showed the abscess cavity as a hyperintense region and also showed a larger region of hyperintensity extending from the cavity margins to the liver surface, corresponding to edematous but morphologically normal liver tissue. After treatment, the abscess cavity became homogeneously hypointense on T1-weighted images, corresponding to liquefaction of the abscess center. With successful treatment, concentric rings corresponding to (a) an inner margin of inflamed granulation tissue, (b) bands of type I collagen, and (c) the outer margin of atrophic and/or mildly inflamed liver tissue became prominent on T1- and T2-weighted images. T2-weighted images showed rapid resolution of the perifocal hepatic edema.     

MRI of female genital and pelvic organs during sexual arousal

We utilized contrast enhanced magnetic resonance imaging (MRI) to delineate the anatomy of the female genital and pelvic organs during sexual arousal. Eleven healthy pre-menopausal women and eight healthy post-menopausal women underwent MRI of the pelvis while watching an erotic video. A 1.5 Tesla MR system was used to produce T1-weighted images following administration of MS-325, a gadolinium-based blood pool contrast agent. Selected structural dimensions and enhancement were measured prior to and during sexual arousal. In both pre- and post-menopausal subjects, vestibular bulb and labia minora width increased with arousal. Enhancement measurements increased in the bulb, labia minora and clitoris in both pre- and post-menopausal subjects, and in the vagina in pre-menopausal subjects. There were no marked changes in size or enhancement of the labia majora, urethra, cervix, or rectum during sexual arousal in pre- or post-menopausal subjects. Using MRI, we observed specific changes in the female genitalia and pelvic organs with sexual arousal, in both pre- and post-menopausal women. MRI can potentially provide detailed anatomical information in the assessment of female sexual function, particularly with regard to changes in blood flow.     

Child Poverty in the European Union: the Multiple Overlapping Deprivation Analysis Approach (EU-MODA)

Poverty has serious consequences for children’s well-being as well as for their achievements in adult life. The Multiple Overlapping Deprivation Analysis for the European Union (EU-MODA) compares the living conditions of children across the EU member states. Rooted in the established multidimensional poverty measurement tradition, EU-MODA contributes to it by using the international framework of child rights to inform the construction of indicators and dimensions essential to children’s material well-being, taking into account the needs of children at various stages of their life cycle. The study adds to the literature on monetary child poverty and material deprivation in the EU by analysing several age-specific and rights-based dimensions of child deprivation individually and simultaneously, constructing multidimensional deprivation indices, and studying the overlaps between monetary poverty and multidimensional deprivation. The paper demonstrates the application of the EU-MODA methodology to three diverse countries: Finland, Romania and the United Kingdom. The analysis uses data from the ad hoc material deprivation module of the EU-SILC 2009 because it provides comparable micro-data for EU member states and contains child-specific deprivation indicators.
