[Mechanical ventilatory parameters guided by the low flow pressure-volume curve in patients with acute lung injury/acute respiratory distress syndrome].
Mechanical ventilation may contribute to lung injury and then enhance systemic inflammation. Optimal ventilatory parameters such as tidal volume (VT) and positive end expiratory pressure (PEEP) can be determined using different methods. Low flow pressure volume (P/V-LF) curve is a useful tool to assess the respiratory system mechanics and set ventilatory parameters. ⋯ P/V-LF curves information allowed us to adjust ventilatory parameters and optimize gas exchange without detrimental effects on oxygen delivery in mechanically ventilated ALI/ARDS patients.

Case Reports[Hypocalcemic cardiomyopathy secondary to hypoparathyroidism after a thyroidectomy: report of one case].
Calcium plays a central role in ventricular function. We report a 37 year-old woman with chronic hypoparathyroidism and hypocalcemia secondary to a thyroidectomy performed when she was 18 years old, as treatment for a Graves Basedow's disease. ⋯ Calcium supplementation in addition to diuretics, captopril and digoxin were followed by rapid clinical improvement. Follow up until 18 months showed persistent left ventricular dilatation and systolic dysfunction, with improvement of all the other echocardiographic findings.
