[Hypernephroma with contralateral renal artery stenosis. Therapeutic choices].

We report a case of renal adenocarcinoma with contralateral stenosis of the renal artery. We describe the causes of hypertension in renal cancer and investigative techniques leading to the discover of a vascular implication in hypertension. We debate of the different surgical techniques for renal revascularisation with special regard to splenorenal anastomose.

[Prosthetic replacement in a case of invasion of the inferior vena cava by a recurrent hypernephroma].

We report a case of inferior vena cava resection and reconstruction for recidivant renal cell carcinoma. We describe the collateral circulation of the renal veins and its importance in the treatment of inferior vena cava involvement. We debate of the indications and of the different surgical techniques for reconstruction of the inferior vena cava.

[Contralateral adrenal metastasis of hypernephroma. Report of 2 cases and review of the literature].

We report 2 cases of surgically treated heterolateral adrenal metastasis from renal cell carcinoma. The value of the CT-scan in the diagnosis of adrenal pathology is debated. The substitutive hormonal treatment post bilateral adrenalectomy is discussed.

[Primary aortoduodenal fistula: apropos of 2 cases].

Aortoenteric fistulas are rare. Located at various level of the gastrointestinal tract - from the esophagus to the rectum - the most frequent are aortoduodenal, secondary to abdominal aortic aneurysms. Two new cases, successfully treated, are reported.

Effect of histamine on canine gastric mucosal adenylate cyclase.

The effects of histamine, Nalpha-dimethylhistamine, 4,5-methylhistamine, Ntau-methylhistamine, pentagastrin, carbachol, and NaF on the adenylate cyclase activity from canine gastric mucosa were investigated in cell-free preparations. In gastric fundic mucosa, histamine (10(-4) M), Nalpha-dimethylhistamine (10(-4) M), 4,5-methylhistamine (10(-4 M), and NaF (10)-2) M) significantly (P less than 0.001) increased adenylate cyclase activity (means+/-SE) by 44.
