Hidradenitis suppurativa (HS) is a disorder of the apocrine gland causing a chronic, recurrent and painful inflammation. It is a disabilitating condition and, though many therapeutic options are available, the response is often ineffective in most cases and patients can present many recurrences with physical and psychological sequelae. Recent data had shown increased interleukin (IL)-17 serum levels in patients with HS. Psoriasis is a chronic immune-mediated inflammatory disorder and new evidences have shown the role of Th17 cells in its pathogenesis and the therapeutic efficacy of anti-IL-17 antibodies. We present a case of a patient suffering from psoriasis and HS successfully treated with anti-IL-17 antibodies for both conditions. This is the first case report of HS treated with secukinumab.

Back-analysis of a Large Landslide in a Heterogeneous Rock Mass

Flysch is a sedimentary rock consisting of a rhythmic alternation of hard (limestone, sandstone, siltstone) and weak (marl, mudstone, claystone) layers. Because of the presence of layers with different physical properties the mechanical characterization of heterogeneous rock masses such as flysch is a real challenge. Different methods have been proposed in the literature to characterize flysch, combining empirical classification indexes with laboratory tests. Most of these methods, however, were specifically designed for tunneling and underground excavations and their applicability to slope stability problems is not yet fully investigated. In this study, we analyze a large landslide in a cretaceous flysch rock in order to compare the mobilized strength at failure with those predicted by the modified GSI method (Marinos and Hoek, 2001). The landslide occurred in the Savena River basin (Northern Apennines of Italy) on April 6, 2013 with a volume of about 3 million cubic meters. Soon after the failure, geological, geotechnical, and geophysical investigations were carried out to detect the failure mechanism and define the landslide geometry. Back-analyses of the failed slope were performed using both limit equilibrium and finite difference methods to estimate the in situ strength of the flysch. The results show that the mobilized rock mass cohesion is very low and that the GSI method can predict the in situ strength only assuming a very high disturbance factor. Moreover, the analysis shows that the linearization criteria proposed in literature to compute the equivalent Mohr-Coulomb parameters remarkably overestimate the rock mass strength.
