[ role of imaging in lower gastero-intestinal bleeding]

Lower gastrointestinal bleeding means bleeding from sites distal to the ligament of Treitz. The management of haemorrhage involves two folds: first an evaluation of the hemodynamic status and resuscitation when necessary and as soon as possible aetiological investigation. Advances in endoscopic, radiological and surgical equipment and techniques offer an efficient multidisciplinary approach. Colonoscopy usually allows aetiology diagnostic and in some cases haemostasis. Imaging is useful in major haemorrhage, and sometimes enables endovascular treatment. Surgical treatment depends on aetiology, in some cases emergent surgery is the only possible way to obtain haemostasis

[Ewing's sarcoma in old patients-a case report]

The authors report a case of localized Ewing's sarcoma at left femur in a 42-years-old patient, revealed by an hydarthrosis of the knee, that was the only sign of appeal.

Depistage pre-operatoire des adenomes parathyroidiens par ultrasonographie

The authors reports the results of 27 patients affected by primary hyperparathyroidism explored by ultrasonography before the operation. The method's sensibility is of 75%, the specificity of 89% and trustiness of 85%. The cervical echography is a choice method of parathyroidian adenoma presperatory track and it should be systematic before all cervicotomy or before all grave hypercalcemia
