WEB technology--the future of teleradiology?

With the widespread use of the Internet, standard browsers are widely available in radiological and clinical departments. So far the limited speed of the Internet has made teleradiology via the Internet too slow for practical use, but many hospital LANs are now connected to the World Wide Web through high speed access. The new JavaScript technology has made it possible to view examinations with web browsers as simple images instead of sending the full examination data.

Production of cyclomaltononaose (delta-cyclodextrin) by cyclodextrin glycosyltransferases from Bacillus spp. and bacterial isolates.

The conversion of soluble starch to cyclomaltohexaose (alpha-CD), cyclomaltoheptaose (beta-CD), cyclomaltooctaose (gamma-CD) and cyclomaltononaose (delta-CD) by cyclodextrin glycosyltransferases (E.C. 2.

MR imaging of the wrist in carpal tunnel syndrome.

Purpose: To determine whether specific parameters measured on MR images correlated to electrophysiological changes in carpal tunnel syndrome (CTS).

Material And Methods: Prospective clinical examinations were made of 20 patients with suspected CTS. We performed bilateral electrophysiological examinations of the median nerve and bilateral MR imaging of the wrists.

Comparison of clinical judgment and diagnostic ultrasonography in the diagnosis of acute appendicitis: experience with a score-aided diagnosis.

Objective: To evaluate the diagnostic accuracy of clinical judgment and diagnostic ultrasonography (US) used routinely and to create a scoring system to aid diagnosis.

Design: Prospective, double-blind study.

Setting: University hospital, Denmark.

[Should fasting prior to ultrasound examination of the gallbladder, the biliary ducts and the pancreas have to include not-drinking?].

From May to September 1991, 49 patients were examined by ultrasound (Picker CS 9000, 3.5 MHz curved array transducer) before and 30 minutes after drinking 150 ml of water. The volume of the gallbladder decreased significantly from a mean of 23.

Observer variability in measurements of carpal bone angles on lateral wrist radiographs.

Determinations of carpal bone angles are used in the clinical evaluation of carpal malalignment. Eleven frequently referred radiological measures in lateral projection of the wrists in 23 wrists were assessed using different definitions of axes. Interobserver- and intraobserver variations were calculated.

Measurements of carpal bone angles on lateral wrist radiographs.

Measurements of carpal bone angles on lateral wrist radiographs can be of assistance in the diagnostic evaluation of wrist malalignment. A series of 75 normal wrists was examined by use of a standardized radiographic technique. The normal carpal bone angles were determined using the bone axes with the least observer variability (mean and range): radiolunate, -1.

[Naproxen versus indomethacin as night-time medication for patients with rheumatoid arthritis].

The investigation consisted of a double-blind cross-over study of the effect of 75 mg indometacin, 500 mg naproxen or a placebo in 63 patients with rheumatoid arthritis accompanied by night pain and morning stiffness. All the patients received day treatment with 250 mg naproxen b.i.

Impairment of grip function in rheumatoid arthritis--studies with a simple hand test.

A new, simple and quick method for assessment of impaired grip function was evaluated in a rheumatology department, 208 of 211 patients with definite rheumatoid arthritis were unable to do the test, 48 of these patients had regarded their hands as unaffected when questioned. The impairment of grip function was closely related to clinical and functional observations but not related to the most common laboratory tests. The study confirms the hypothesis that almost all patients with RA are unable to do the hand test, even those who consider their hand function as normal.

Construction of a simple test for assessment of hand function in primary care. Theories and experimental trials for the test situation.

This paper describes a hand test consisting of three steps to test the subject's ability to grasp firmly another person's hand to hold a pencil firmly with fingers II-V with straight knuckles and maximally flexed finger joints, while the investigator pulls the pencil to hold on to a piece of paper with a rounded pinch grip between thumb and index finger while the investigator pulls the paper with a rounded pinch grip with submaximal strength. All three steps must be performed with each hand without causing pain. The test was an adequate parameter for the grip function, and at the same time could register work-load elicited pain, strength, and mobility.

Radiography of the wrist. A new device for standardized radiographs.

A number of methods exist for determination of carpal bone angles on lateral wrist radiographs. However, there is no general or precise definition of the angles measured. In this study the positioning of the wrist is emphasized and a device used to obtain standardized radiographs is presented.

The effect of a serotonin antagonist ketanserin on acute urinary retention.

The serotonin antagonist ketanserin has in a single case been found effective in promoting bladder emptying in a patient with first time acute urinary retention on basis of benign prostatic hypertrophy. The mechanism behind is probably an alpha-receptor blockade.

Serum aminoterminal type III procollagen peptide in inflammatory and degenerative rheumatic disorders.

Measurement of the aminoterminal type III procollagen peptide in serum has been suggested as a marker of the biosynthesis of collagen type III, a major connective tissue component in repair processes. In the present study the propeptide level correlated with the inflammatory synovial mass in rheumatoid arthritis and osteoarthritis. This implies that the propeptide level reflects the collagen type III synthesis occurring in the synovial repair processes, whether they were caused by inflammatory or degenerative rheumatic disorders.

The frequency of rheumatoid arthritis among relatives of probands with definite ankylosing spondylitis.

We studied families of 23 unrelated HLA-B27 positive probands with definite ankylosing spondylitis to investigate the occurrence of rheumatoid arthritis. The prevalence of RA among these relatives was significant higher (2.91%; 0.

Antikeratin antibodies in rheumatoid arthritis. Methods and clinical significance.

A method to determine antikeratin antibodies (AKA) is described. AKA were detected by indirect immunofluorescence technique on rat esophagus as antigen in sera of patients with definite rheumatoid arthritis (RA). The frequency of AKA in rheumatoid factor (SCAT/Waaler-Rose) positive RA was 64% and in SCAT-negative RA, 28%.

The effects of a new serotonin receptor antagonist (ketanserin) on lower urinary tract function in patients with prostatism.

Ten male patients with prostatism, median age 63 years (range 50 to 70 years) were given an intravenous injection of a new serotonin antagonist, ketanserin, at a dose of 10 mg., and were investigated urodynamically before and after injection. A statistically significant increase in maximum and mean flow rates and a statistically significant decrease in urethral pressure profile measurements was observed.

Minimal walking distance following exercise treatment in patients with arterial occlusive disease.

79 patients with intermittent claudication were tested with peripheral blood pressure measurement and determination of minimal walking distance before and after a 3 months' period with scheduled walking exercises under supervision. No change in peripheral blood pressure was observed following the treatment whereas the minimum walking distance was increased with statistical significance. The gain was most pronounced in patients with an initial combination of high peripheral pressures and short walking distances.
