[Diagnostic and therapeutic angiography in severe retro- and subperitoneal hematomas].

This study of the value of arterial angiography was carried out in 22 patients with serious retroperitoneal hemorrhage. In the first instance, this investigation determines the number of hemorrhages, their sites and flows. Later on it can be used to evaluate the volume of the hemorrhage and its effect on vascularisation of the abdominal viscera so that an initial prognosis can be made.

[Endocavitary drainage (Monaldi's technic) in the treatment of pulmonary abscess].

The technique of intracavitary aspiration introduced by Monaldi in 1938 in the treatment of tuberculous cavities and then applied by him in the treatment of lung abscesses was forgotten for nearly 30 years. The advent of antibiotics and their success explain its abandonment. It may take an important place again in the treatment of difficult cases, as a last resort, after failure of properly conducted classical medical treatment.

[Paradoxical systemic emboli. 5 case reports].

Paradoxical systemic embolism by venous emboli in the arterial circulation can be explained by a right-left shunt. In 5 patients, the diagnosis of paradoxical emboli was definite in three cases, and suspected in two others. Venous, arterial and cardiac angiography define the anatomical criteria which alone can confirm the diagnosis.

[Purulent pleurisy caused by anaerobic bacteria. Apropos of 2 observations].

Purulent pleural effusions due to anaerobic organisms secondary to infections of the pulmonary parenchyma are complications which often occur following the inhalation of organisms from the buccal cavity. The most commonly found organisms belong to the endogenous anaerobic flora of Veillon. Rapid encystment of the pleural collection is suggestive of this diagnosis.

[Autotransfusion in experimental hemoperitoneum. Hematologic study].

In order to study the hematologic repercussions of pre-operative autotransfusion, ruptures were made in experimental spleens followed by retransfusion after intraperitoneal barbotage of long duration in 8 dogs. This was performed without any heparinization. The following facts could be established:--although the blood shed was rich in red globules, it presented major alterations with a loss of clotting agents and evidence of fibrinogenic degradating elements.

[Metabolic acidosis and intravenous injections of fat emulsions (role of phospholipids. Experimental study)].

In explanation of metabolic acidosis during parenteral nutrition, the authors considered the supply of H+ ions by fat emulsion, containing phospholipids of egg or soy. During intravenous infusions of 24 grams of lecithins to two healthy subjects, they observed an increased output H+ ions in urine, about 74,05 and 75,88 mEq, and a metabolic acidosis of the plasma. The theorically forcasted supply of production was 74,6 mEq.

[Severity factors and diagnosis of nonhemodynamic pulmonary edemas].

This syndrome is characterised by changes in the pulmonary capillary bed allowing filtration of edema fluid rich in proteins. It provokes an alveolo-capillary block and a fall in compliance. Positive diagnosis is envisaged from the clinical circumstances implicating a change in the pulmonary capillaries (blast, shock, microemboli).
