RHIZOtest: a plant-based biotest to account for rhizosphere processes when assessing copper bioavailability.

The ability of the free ion activity model (FIAM), the terrestrial biotic ligand model (TBLM), the diffusive gradients in thin films (DGT) technique and a plant-based biotest, the RHIZOtest, to predict root copper (Cu) concentration in field-grown durum wheat (Triticum turgidum durum L.) was assessed on 44 soils varying in pH (3.9-7.

[Endoscopic hemostasis of hemorrhagic gastroduodenal ulcers].

The mortality rate for peptic ulcer bleeding has remained constant for several decades, despite advances in surgery and intensive care, and this has given rise to an interest in therapeutic hemostatic endoscopy. Thus, endoscopy in the treatment of peptic ulcer hemorrhage would be undertaken with the aim of obtaining an early and precise diagnosis of the hemorrhagic lesions, to arrest active bleeding and/or to prevent rebleeding. In the selection of patients justifying an endoscopic hemostatic treatment, intervene clinical criteria (age, concomitant pathologies, current medication, hemodynamic parameters), endoscopic criteria (active arterial bleeding, visible vessels).

[Percutaneous drainage of splenic fluid accumulations. Apropos of 4 cases].

Four patients with solitary or multiple splenic fluid collections were treated by ultrasound guided percutaneous needle aspiration and drainage. There was one unilocular abscess, three infected hematomas, one large hematoma and a complex lesion with locular and perisplenic involvement. Percutaneous drainage and antibiotics were curative in one patient.

[Hydatid cyst of the pancreas. Apropos of 2 cases].

Two new cases of pancreatic hydatidosis are reported. The diagnosis of a cystic lesion of the pancreas has been easily established owing to the modern imaging techniques, especially to computed tomography. The hydatid nature has also been recognized before surgery on the basis of the epidemiological data, the existence of a calcified shell in one case, and positive serology in the other.

[Fibro-inflammatory polyposis of the stomach: apropos of a case].

The stomach fibro-inflammatory-polyp is distinguished from the eosinophilic granuloma by some authors because of their geographic assessments. It is an inflammatory affection represented by a pseudo tumoral lesion. We present a case concerning a woman, 62 years old, who presented since 10 years a Biermer anaemia; a neoplastic affection was suspected, and then denied by histopathologic exam.

[Endosalpingosis: apropos of a case of colonic localization].

The endosalpingosis is a benign affection which is in the most often asymptomatic. It means the presence of tubal mucosa in ectopic location; often in the tubal wall; the pelvic peritoneal and adjacent lymph node. We present here a colic endosalpingosis case with intestinal occlusion.
