[Acute leukemia revealed by bone magnetic resonance imaging: Two pediatric case reports].

Bone and joint pain are common causes of pediatric consultation for a variety of etiologies. The causes are mostly traumatic or infectious or have an inflammatory origin. Acute leukemia (AL) can sometimes begin with osteoarticular signs and radiological investigations such as magnetic resonance imaging (MRI) can help guide the diagnosis.

[Small bowel volvulus due to midgut malrotation: value of Doppler sonography. A case report].

A case of small bowel volvulus due to midgut malrotation in a 4 years-old child complaining of vomiting and abdominal pain. Diagnosis was made by a Doppler ultrasound showing the volvulus and the intestinal malrotation. We are discussing the interest of this technique.

Rupture of an abdominal aortic aneurysm after endovascular graft placement and aneurysm size reduction.

Reduction in aneurysm size during the months after an endovascular graft placement generally is considered one of the criteria of success. We report the case of a patient with an abdominal aortic aneurysm rupture occurring 9 months after a bifurcated endovascular graft placement despite a greater than 45% reduction in size noted on contrast-enhanced computed tomography scan performed at 7 months. Biomaterial modifications of the stent and of the Dacron explanted stent-graft are analyzed.

[Treatment of post-traumatic dislocation of the patella. Critical study of 29 cases (author's transl)].

The treatment of post-traumatic dislocation of the patella depends on careful examination. One should propose surgery in most cases, for not only one may leave a foreign body within the joint, but above all correction of the extensor apparatus is necessary in more than 50 p. cent of cases, to avoid a recurrence.
