USEFULNESS OF SURGICAL LUNG BIOPSIES AFTER CRYOBIOPSIES WHEN PATHOLOGICAL RESULTS ARE INCONCLUSIVE OR SHOW A PATTERN SUGGESTIVE OF A NONSPECIFIC INTERSTITIAL PNEUMONIA

Usefulness of surgical lung biopsies after cryobiopsies when pathological results are inconclusive or show a pattern suggestive of a nonspecific interstitial pneumonia

Abstract Background Although increasing data supports the use of transbronchial lung cryobiopsies (TBLCs) for the diagnosis of diffuse parenchymal lung diseases (DPLDs), its role as an alternative to surgical lung biopsy (SLB) is still under debate.The aim of this study was to assess the benefit of additional SLBs performed in selected patients aft

Solving the quartic by conics

Two conic sections C1{C}_{1} and C2{C}_{2} in the Euclidean plane that pass through two given points can generally have two further points of intersection.It is shown how these can be constructed acure face lotion using compass and ruler.The idea is to construct the degenerate conics in the pencil of the two conics C1{C}_{1} and C2{C}_{2}.Their int
