Stenosis and renographic characteristics in renovascular disease.

Unlabelled: This study was designed to determine the degree of renal artery stenosis (RAS) which produces changes in renographic parameters.

Methods: The angiographic severity of luminal narrowing in RAS was compared to 131I-hippuran renographic characteristics in 72 patients who have been selected for renal angiography because of suspected renovascular hypertension.

Results: Significant differences in Tmax, T1/2 and counts under the curve to Tmax were apparent at 30% of arterial luminal narrowing when stenotic and nonstenotic kidneys were compared.

[Ultrasonography of the leg veins is cost-effective and can be the preferred diagnostic study in suspected pulmonary embolism].

Objective: To determine whether compression ultrasound examination of both legs, to detect deep venous thrombosis, can be the examination of first choice in patients clinically suspected of pulmonary embolism, assuming that the therapy of thrombosis is the same as the therapy of embolism.

Design: Prospective study.

Setting: St.

Potassium supplements prevent serious hypokalaemia in colon cleansing.

The association between colonic cleansing and hypokalaemia was studied prospectively by monitoring the serum potassium levels in four groups of patients: groups 1 (55 patients), 2 (72 patients), and 3 (97 patients) received the same 2-day preparation of 15 g magnesium sulphate and 10 mg bisacodyl twice daily; group 4 (96 patients) received a 1-day preparation of 2.4 mg sennoside per kg of bodyweight. Groups 1 and 2 were on diuretics, but only group 2 received potassium supplementation.

Painful irritable bowel syndrome and sigmoid contractions.

Fifteen patients with abdominal pain compatible with the irritable bowel syndrome (IBS) were examined by barium enema and pressure recording. Strong circular contractions of the sigmoid colon and pressure recordings correlated with the characteristic pain in 13 of the 15 patients. In 15 control patients no pain occurred.

[Motility of the sigmoid in irritable bowel syndrome and colonic diverticulosis].

The results of pressure recording in patients with irritable bowel syndrome, diverticulosis and diverticulosis with pain were compared with the results in control subjects. The motility showed variable higher values in patients with irritable bowel syndrome. The motility was clearly higher in patients with diverticulosis and in patients with diverticulosis with pain.

Total talar dislocation.

Five patients with the very rare injury of a total dislocation of the talus were retrospectively studied. Rapid open reduction had successfully been performed in all patients. The mean followup was 4.

Cholecystokinetic cholecystography.

A prospective clinical trial of 100 patients receiving either intramuscular ceruletide or a fatty meal to contract the gallbladder after oral cholecystography is described. The percentage reduction of the gallbladder area after 30 min of stimulation was not significantly greater with ceruletide (49%) than with a fatty meal (44%) (t-test: p greater than 0.3).

Ectopic right bronchus: indication for bronchography.

Ectopic right-sided bronchus is a rare anomaly. In this retrospective study, eight patients are described. All were from a population that clinically was suspected of suffering from chronic bronchitis.
