[Asymptomatic pulmonary embolism and venous thrombosis of the lower limbs. Study with spiral x-ray computed tomography]. / Embolie pulmonaire asymptomatique et thrombose veineuse des membres inférieurs. Etude par tomodensitométrie hélicoïdale.

AIM: Spiral Computed Tomography (CT) allows diagnosis and follow-up in pulmonary embolism (PE). MATERIAL AND METHOD: We studied prospectively with spiral CT 21 patients to evaluate the frequency and the extent of asymptomatic PE in the patients with lower limbs venous thrombosis and no pulmonary symptomatology. RESULTS: We observed a asymptomatic PE in 8/21 cases (34%). Extensive pulmonary thrombosis could be observed despite normal presentation. There was no association between the localization of PE topography and, the extent of the lower limb venous thrombosis extent. CONCLUSION: This study shows about the capability for CT to evaluate PE severity and clinical underestimation PE occurrence.

[Hepatic manifestations in Still's disease]. / Manifestations hépatiques au cours de la maladie de Still.

In children, as in adults, Still's disease usually presents with a hectic fever, a characteristic rash and arthralgia or arthritis. Visceral involvement is however classical; the hepatic manifestations were studied with respect to two cases. Biochemical changes are common, often mild: the commonest abnormality is cytolysis. Jaundice is less frequent and hepatic involvement may in exceptional cases be life threatening, usually in cases of serious polyvisceral disease often with disseminated intravascular coagulation. These manifestations may be spontaneous or secondary to salicylate therapy; the anatomical changes are the same; the salicylate would therefore seem rather to unmask and aggravate an underlying hepatic abnormality.
