ABSTRACT
Tuberculous acute mastoiditis (TAM) is a rare inflammatory infective condition of the mastoid process that can be difficult to diagnose. We presente the case of a 65-year-old women with earache, ear purulent discharge and tenderness of the mastoid tip after long time of medical therapy. Mastoidectomy with attico-antrotomy revealed chronic granulations with an osteitic process of mastoid and tympanic cavity with intact ossicular chain. Standard medical therapy resulted with prompt healing. Despite its rarity, diagnosis of TAM is often delayed, with potentially danger for severe complications.

Enigmatic glassy materials (escorias) and red bricklike materials (tierras cocidas) occur at a restricted stratigraphic level (the top of the Chapadmalal Formation). Materials from one locality near Mar del Plata are attributed to a mid-Pliocene impact event with a radiometric and magnetostratigraphic age of 3.3 million years ago (Ma). An extinction of endemic fauna (including the glyptodonts and flightless cariamid birds) correlates with the unit containing the impact glasses. Moreover, the age of the glasses is coincident within dating uncertainties with a pulselike change in the oxygen isotope marine record in the Atlantic and Pacific Oceans just before the late Pliocene deterioration of the climate.
