Case Reports[Color-coded Doppler sonography in iatrogenic spurious aneurysms in the groin].
Pseudoaneurysm of the femoral artery occurred in five patients (aged between 61 and 82 years) after catheterization of the artery, four times after percutaneous transluminal angioplasty of the leg arteries and once after left-heart catheterization. The pseudoaneurysms were correctly diagnosed by colour-coded duplex Doppler sonography by demonstrating turbulence within the aneurysm and a connection to the femoral artery with bidirectional shunting. ⋯ After 30-35 min flow into the aneurysm had ceased even when the compression was released. Re-examination up to 11 months later (mean of 7.6 months) indicated that the treatment had been successful in all.

Comparative Study[Endoscopic ultrasound in the demonstration and staging of non-Hodgkin's lymphomas of the stomach].
Nine patients (five women, four men, mean age 64.2 [49-77] years) with histologically confirmed gastric non-Hodgkin lymphoma (NHL) were investigated before starting therapy and during follow up, using endoscopic ultrasound, computer-assisted tomography and conventional ultrasound. Of ten gastric NHL infiltrations, nine were demonstrable using endoscopic ultrasound, three by computed tomography and two with conventional ultrasound. Accurate assessment of the primary tumour stage was possible in six out of eight cases using endoscopic ultrasound, but in none using tomography or conventional ultrasound. ⋯ False positive results were obtained in two cases using endoscopic ultrasound and computed tomography. Regression of the tumour and of paragastric lymph nodes on radio-chemotherapy was demonstrable in two cases, and progression in one using endoscopic ultrasound; the other techniques showed progression of extragastric lymphoma involvement in only one case. Endoscopic ultrasound is an efficient method for demonstration and local staging of gastric non-Hodgkin lymphomas.

Comparative Study[Pulsatile insulin secretion into the portal vein in liver cirrhosis].
To characterize the pulsatile liberation of pancreatic hormones, blood was taken from the portal vein of four patients (three men, one woman; aged 65-71 years) with alcoholic (n = 3) or posthepatitic (n = 1) liver cirrhosis. The concentrations of glucose, insulin, C-peptide and glucagon were measured within one minute. ⋯ Oral glucose loading with 100 g increased the insulin and C-peptide swings, but not their periodicity. This indicates that pulsatile insulin secretion is amplitude not rate driven.

Case Reports[Patent foramen ovale and platypnea after pneumonectomy].
Six months after a pneumonectomy for myeloma, which had preoperatively been indistinguishable from bronchial carcinoma, a 50-year-old man presented with shortage of breath, cyanosis and episodes of syncope on standing or walking, symptoms which improved on lying down (platypnea). On one occasion these symptoms necessitated controlled artificial ventilation, but even at an inspiratory oxygen saturation of 100%, blood gases only partially improved (pCO2 27 mm Hg, pO2 67 mm Hg, O2 saturation 93%). ⋯ Part of the inferior vena cava flow passed into the left atrium via a patent foramen ovale: it is likely that this shunt increased in the upright position. After surgical closure of the patent foramen ovale and partial relocation of the heart (with a vicryl net) the patient has now remained free of symptoms for 5 years.
