Effective immunosuppressive therapy in a patient with primary pulmonary hypertension.

The case history is described of a young woman who presented with primary pulmonary hypertension and non-specific inflammatory signs. The patient received prolonged immunosuppressive treatment with low dose methotrexate and prednisone without any vasodilator agent. After one year the pulmonary artery pressure fell from a mean value of 47 mm Hg to 30 mm Hg and there was a corresponding clinical response.

Prevention of atrial tachyarrhythmias after non-cardiac thoracic surgery by infusion of magnesium sulfate.

The possible role of magnesium sulfate (MgSO4) infusion in the prevention of atrial tachyarrhythmias after non-cardiac thoracic surgery was evaluated through a prospective study of two hundred patients who underwent non-cardiac thoracic surgery. The patients (who fulfilled the following requirements among others: no myocardial infarction in the previous six months, normal renal function, no use of digitalis or antiarrhythmic drugs, not undergone emergency operations or video-assisted thoracic surgery), were randomly assigned to receive MgSO4 infusion in all circumstances (Mg group), or either no treatment or, if aged over 70 or in cases of pneumonectomy or an intrapericardial procedure, application of digoxin starting on the day of operation (control group). 95 patients were enrolled in the Mg group and 105 in the control group.

Lung resections concomitant to coronary artery bypass grafting.

From 1980 through 1993 ten patients underwent concomitant coronary artery bypass grafting and lung resection via median sternotomy. In eight patients a lung malignancy was resected, of which one was a small cell lung cancer. The lung resection was carried out before cardiopulmonary bypass in eight patients and during cardiopulmonary bypass in two.
