Ground deformation reveals the scale-invariant conduit dynamics driving explosive basaltic eruptions
The mild activity of basaltic volcanoes is punctuated by violent explosive eruptions that occur without obvious precursors. Modelling the source processes of these sudden blasts is challenging. Here, we use two decades of ground deformation (tilt) records from Stromboli volcano to shed light, with unprecedented detail, on the short-term (minute-scale) conduit processes that drive such violent volcanic eruptions. We find that explosive eruptions, with source parameters spanning seven orders of magnitude, all share a common pre-blast ground inflation trend. We explain this exponential inflation using a model in which pressure build-up is caused by the rapid expansion of volatile-rich magma ri…
Peritoneal tuberculosis in the differential diagnosis with peritoneal carcinomatosis: Case report and literature review
Tuberculosis is a severe public health problem in developing countries, but it is taking on the characteristics of a global epidemic. By virtue of migration flows, in fact, we are observing a resurgence of this disease in western countries, in all its forms including the genital one. The problem became more serious with the emergence of multidrug-resistant mutant (MDR) strains of Mycobacterium Tuberculosis. In this paper we describe a case of peritoneal tuberculosis, whose diagnosis was histologically made after laparoscopic examination. Laparoscopy proved crucial for the differential diagnosis with peritoneal carcinomatosis, particularly following the discrepancy in the results provided by…
