Diagnostic accuracy of Doppler ultrasound technique of the penile arteries in correlation to selective arteriography

In 63% of 265 patients with erectile dysfunction a relevant arterial inflow disturbance was found by Doppler ultrasound examination. Correlation between Doppler and arteriography in 58 patients showed an accuracy of 95% in detecting penile arteries and an accuracy of 91% in discovering a pathological arterial pattern (arterial anomaly or arteriosclerotic obstruction). In 15 patients the arterial inflow was measured additionally by Doppler ultrasound technique after intracavernosal injection of vasoactive drugs (IIVD) (7.5 mg papaverine and 0.25 mg phentolamine). This technique proved to be more reliable than in the flaccid state and markedly facilitated localization and assessment of pathological changes of the cavernosal arteries

Antillean Visions: Maps and the Making of the Caribbean

A map, in its most reductive form, is a potent emblem of conquest, representing—by turns—the subjugation of peoples, the destruction of indigenous cultures, the beating back of ignorance, and the taming of nature. They are equally powerful tautologies, reifying and rendering concrete specific belief systems such that their “rightness” or righteousness seems indisputable. Maps are also material manifestations of the long arc of history, providing insights into world views and political, cultural, and socio-economic agendas (both individual and collective). Maps, then, are far more than the sum of their parts, as Antillean Visions: Maps and the Making of the Caribbean makes clear. Cutting across cultures and a diverse—though geographically bounded—region, this thought-provoking exhibition surveys the impact of cartography over the course of more than five hundred years. Beyond highlighting key modes of creation and representation, Antillean Visions probes the dissemination, reception, and interpretation of maps of the Caribbean, cross-referencing the visual and the historic, the anthropological and the biological. Similarly, it provides us with glimpses into our own realities, viewed through the lenses of contemporary map-making, including participatory experiences and games
