Postpartum hemorrhage is leading cause of maternal mortality and still remains a challenging condition to treat and hysterectomy may be required to control the bleeding once medical interventions fail. These strategies are not always successful and a direct approach in activating the coagulation system can be more effective and life saving. We describe here the mechanism of action of rFVIIa, review of literature and its use in 10 cases with different causes for PPH with good response.

This trial will test whether torasemide-PR possesses antifibrotic properties, which may provide an additional benefit beyond diuresis in patients with chronic heart failure.

Serial echocardiography and Doppler were used to monitor the progression of pressure-overload produced by banding the ascending aortas of young cats. The peak Doppler gradient across the band increased (as the animals grew in size) from 42 +/- 4.2 mmHg at 1 wk to 78 +/- 4.5 mmHg at 2-3 mos. Echocardiographic measurements of septal wall thickness increased significantly at 1 wk. Global ventricular function was unaltered in banded cats versus shams at each time point. However, in the subgroup of animals with an aortic-constricted area of < 0.025 cm2 at 1 wk, fractional shortening decreased by 40% at 2-3 mos. Contractile abnormalities were present in isolated myocytes from hypertrophied hearts. Mechanical function was more profoundly depressed in cells from hearts with echocardiographic evidence of ventricular decompensation. Echocardiographic and Doppler studies assessed cardiac size and function and identified indexes predictive of global and cellular myocardial dysfunction. The use of noninvasive techniques as a predictor of failure makes the feline model of progressive left ventricular pressure-overload useful for studies of cellular and molecular factors regulating not only the development of cardiac hypertrophy but also the transition from compensated hypertrophy to myocardial failure.
