An unusual adverse drug reaction?

Introduction: Adult Still Disease (ASD) is a rare (incidence 1-1,6/1,000,000 in Europe) seronegative polyarthropathy diagnosed with clinical criteria, excluding other etiologies. Minocycline, a semisynthetic derivative of tetracycline, has been associated with many adverse effects. We present the case of a 18-years-old man with a high suspicion of an adverse drug reaction (ADR), that was finally diagnosed of ASD.

Non-pigmenting cutaneous-mucosal fixed drug eruption due to piroxicam.

Background: Piroxicam is a widely used anti-inflammatory drug. Most adverse reactions affect gastrointestinal system, liver and skin. Fixed drug eruption although very unusual, has also been described, but with cutaneous involvement exclusively.

[Noninvasive ventilator support in patients with chronic obstructive pulmonary disease. A comparison of 2 methods].

The external high frequency oscillation around a negative baseline (EHFO-NB) is a new mode of non-invasive ventilatory support which could replace or complement nasal intermittent positive pressure ventilation (NIPPV) for treatment of patients with chronic obstructive pulmonary disease, both in the decompensation phases and as preventive measure in intercrisis periods. This was a prospective study in which tolerance and short term effects on acid-base balance and gas interchange of both NIPPV and EHFO-NB in twenty patients with severe chronic obstructive pulmonary disease were compared. With both methods similar decrease in PaCO2 and increases in pH were observed, with decrease and increase in respiratory frequency when using NIPPV and EHFO-NB, respectively; the latter in association with the high oscillation frequencies used.
