[Hemodynamic effects of enoximone and comparison with dobutamine in patients with chronic respiratory insufficiency and pulmonary arterial hypertension].

The aim of this study was to assess the effects of enoximone on the right ventricle and pulmonary hypertension in 10 patients (53 to 84 years) with chronic obstructive airway disease resulting in acute or chronic respiratory failure requiring mechanical ventilation in 9 cases. These effects were compared with those of dobutamine. All patients were in sinus rhythm and 6 had signs of right ventricular failure.

Three cases of preleukemic myelodysplastic disorders with the same translocation t(1;3).

The same translocation, t(1;3)(p36;q21), was observed in three patients with a preleukemic syndrome presenting as a myelodysplastic disorder. It was the only chromosomal abnormality in two patients; and the third patient had 12p- and 15q- as additional abnormalities. The three cases evolved into acute nonlymphocytic leukemia.
