Adherence to vitamin and mineral supplementation after bariatric surgery - A two-year cohort study.

Background: Lifelong vitamin and mineral supplementation is recommended after bariatric surgery to prevent nutritional deficiencies, but it is not clear to which extent patients adhere to the recommended medication. The aim of this study was to assess adherence to supplementation. Additionally, we assessed predictors of low adherence and biochemical deficiencies.

Evidence of poor vitamin status in coeliac patients on a gluten-free diet for 10 years.

Background: Patients with coeliac disease are advised to keep to a lifelong gluten-free diet to remain well. Uncertainty still exists as to whether this gives a nutritionally balanced diet.

Aim: To assess the vitamin nutrition status of a series of coeliac patients living on a gluten-free diet for 10 years.

[Lateral urethrocystography in digital subtraction technique].

The first application of the digital subtraction technique to lateral urethrocystography is described. This methodology facilitates gynecological-urological operations by providing reliable investigation results and an unambiguous image interpretation. Methods and first experiences with the digital subtraction technique in gynecological-urological diagnosis are reported.

[Color-coded duplex ultrasonography compared to phlebography in deep leg and pelvic vein thrombosis].

Between March 1990 and March 1991, in a prospective study, 100 patients (53 men, 47 women, median age 61.5 years) with suspected deep venous thrombosis of the lower extremities, colour duplex ultrasonography (CDU) (Ultramark 9, ATL) were investigated using the slow-flow technique. The CDU findings obtained for the external iliac vein (distal segment), the common femoral, the superficial femoral and popliteal veins, together with those of the veins of the lower extremity, were compared with the results of phlebography, which is considered to be the gold standard for this type of investigation.
