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.

[Significance of bone changes in the internal auditory meatus in acoustic tumors and in the "empty" enlarged inner ear canal].

The unilateral extension of shortening of the internal auditory meatus is a very safe bony sign of the presence of a neurinoma of the auditory nerve. Differential diagnosis is necessary to exclude an "empty" extended internal auditory meatus. On the other hand, 31% of the definitely established neurinomas do not show up in the plain tomogram.

[Radiation loading problems in petrous bone tomography. Experimental research using film dosimetry on the Alderson phantom].

Using film dosimetry and an Alderson skull phantom, the iso-dose distribution during tomography of the petrous bone was investigated. We were particularly concerned with the radiation dose to the lens of the eye, the critical organ in the skull, and to the inner ear, using different types of examination and various positions of the skull. The choice of suitable film material and standardisation against TLD measurements is crucial for the accuracy of film dosimetry, allowing for correction of film blackening in relation to varying energies.

[High-resolution computed tomography of femur head necrosis].

High resolution CT with reconstruction in the sagittal and coronal planes plays a central role in the diagnosis of necrosis of the femoral head. It provides the diagnostician and surgeon with a means for early diagnosis and for determining the extent and localisation of the bone changes; this assists in planning treatment. Additional diagnostic imaging methods are only necessary in isolated cases.

[Digital subtraction angiography as an aid in decision-making in problematic approaches to the superior vena cava].

By digital subtraction angiography (DSA), diagnostic statements can be made even with low concentrations of contrast medium. Despite the increasing dilution of contrast medium, a definite statement on mediastinal vessel condition is possible in direct visualisation of the arm veins up to the vena cava superior as well as of collaterals using peripheral injection of the contrast medium. Two case histories show that the investigator has definite criteria at his disposal enabling him to forgo frustrating puncture attempts in the area of the vena subclavia, vena jugularis interna and vena anonyma in case of suspected thrombotic vessel closure after long-term parenteral nutrition.

[Spiral tomography with a narrow blurring angle. A valuable supplement to clinical routine].

Narrow-angle tomography with spiral blurring offers for the first time a possibility of combining the advantages of sonography with those of multidimensional tomography. This results not only in an improved image contrast of the tomographs, but also in an image which is largely free from interfering shadows. Hence, it is recommended to employ this method both for organs in the soft parts and, in particular, for exploring specific problems involved in diagnosis of the skeleton.

[Enlarged "empty" internal auditory canal -- its role in differential diagnosis of the acoustic neuroma (author's transl)].

Plain roentgenography of the petrous bone showed in 24 of our otoneurological patients an enlargement of the internal auditory canal. The vertical diameter was more than 8 mm. Otoneurological findings in these patients were mostly the same as found in acoustic neuromas.

[Changes in thyroid function following iodine-containing contrast administration in patients in an endemic goitre area (author's transl)].

A prospective study of thyroid function after the administration of iodine-containing radiographic contrast media was carried out on 119 patients from an area where goitres are endemic. Eighteen patients had a negative TRH test after 28 days. 27.

[Unusual abscess formation in the posterior mediastinum (author's transl)].

Pathological processes in the interpleural space appear on x-ray film as space-occupying growths. The assessment of such processes will always require x-ray films of the thoracic organs in two planes, rotating fluoroscopy and spot films as well as tomography. Additional information is obtained via oesophagus contrast radiography, angiography and mediastinoscopy.

[Indications for the computer tomographic investigation of the suprarenal gland (author's transl)].

The introduction of the third and fourth generation of CT scanners (scan times of 1 to 20 seconds) has brought about a change in the choice of methods for investigating suspected suprarenal disease. The excellent spacial resolution of CT scans permits accurate evaluation of minor changes in the gland. As a result, it is often possible to avoid invasive diagnostic procedures.

[Iodine-induced hyperthyroidism due to contrast media (author's transl)].

A prospective study in an area with endemic goitre showed 18 patients (15.1%) out of 119 investigated with iodine containing contrast media to be hyperthyroid after 28 days. Oral cholecystography led to the highest (27.

[Long-term follow-up after spontaneous contrast extravasation during infusion urograms (author's transl)].

In 1978 we described 18 patients with acute spontaneous rupture of a pelvi-calycine system; these have now been followed up with the exception of four patients. The aim was to determine whether, and how frequently, long-term complications occur, such as chronic persistent rupture and particularly whether local retroperitoneal fibrosis develops. The clinical history, infusion urograms and cinematography provided no evidence of any abnormalities except in one case.

[Improvement of oral cholecystography and cholangiography with ceruletid (author's transl)].

Following oral cholecystography in 100 patients, the conventional "fatty meal" was replaced by an intramuscular injection of Ceruletid in a dose of 0.4 microgram/kg body weight. The synthetic decapetide Ceruletid is a substance with a hormone-like effect on the gastro-intestinal tract.

[Investigation of the small bowel using an intubation method (author's transl)].

Small bowel contrast examinations by an intubation method were carried out in our hundred patients suspected of having small bowel disease. The method described by Sellink was used and the time and expenditure for carrying out the procedure was monitored. The effect of changes in the method on side effects and quality of the results were observed.

[Repeated contrast cisternography after previous use of an oily contrast medium (author's transl)].

Twenty-four control cisternograms were carried out at two to 22 months after lumbar injection of 1.0 to 1.5 ml.
