The safety and efficacy of various methods of accessing the intestinal tract, including needle catheter jejunostomy, have been well described. This review represents an evaluation of the Witzel tube ...jejunostomy as an adjunct to esophagectomy.
The records of 523 patients who underwent esophagectomy for benign or malignant disease from 1976 to 1991 were reviewed. Each patient underwent placement of a tube jejunostomy at the time of esophagectomy and esophageal reconstruction. Utilization of the jejunostomy tube and the complications related to its placement were examined.
The feeding jejunostomy was used in all patients in the initial postoperative period, for more than 3 weeks in 11%, and for more than 2 months in 6.9%. Major complications related to the jejunostomy tube occurred in 11 patients (2.1%). There were no fatal complications.
Tube jejunostomy is a useful adjunct to esophagectomy for providing enteral nutrition during the postoperative period. The Witzel jejunostomy as described herein is comparable in terms of safety, function, and complication rate to the needle catheter jejunostomy and has certain technical advantages. Routine use of tube jejunostomy is recommended in patients undergoing esophagectomy.

Radionuclide X-ray fluorescence analysis (RXRFA), as a non-destructive method, relatively simple and allowing measurements to be carried out in situ, is an excellent tool in research on various ...objects of art. A range of artefacts have been investigated by our laboratory, in part for the purposes of history of art and in part as a basis for restoration works – medieval frescoes in some Czech castles and churches, metal sculptures and objects of applied art, paints and inks of old manuscripts, paintings. Some of these are among the most valuable monuments in the Czech cultural heritage. The contribution of the results of the tests to the investigation of their “life story” and, in some cases, to their conservation, is not negligible. Later additions and repairs can be recognised, and materials and technologies that are close to their historic counterparts can be used in restoration work.
An XRF technique was used for the analysis of fresco paintings. The analysis of paintings makes it possible to examine pigmented materials. An application of the method is used to illustrate the ...technique.
A “Laboratory of Quantitative Methods in Monument Research” is being built at the CTU Prague. Its primary orientation is the investigation of historic architecture, although other objects of art can ...also be investigated. In the first phase, two radiation methods are being established, but it is set up in such a way, that various other methods can readily be added in its future development. The radiation methods chosen for the initial development of the laboratory are: thermoluminescence dating and X-ray fluorescence analysis. The design of the automated TL-reader, built in our laboratories, is adjusted for the purpose of dating of historic brick architecture (which, of course, does not exclude applications for ceramics and other materials). The investigation of renaissance architecture in southern Bohemia and Moravia is under preparation as the first large campaign of this kind in the Czech Republic. Radionuclide X-ray fluorescence analysis has been chosen as the basic analytical method in the laboratory. The possibility of analyses of paintings and fired building materials (bricks, roof tiles) have been investigated. The first results in both the areas are very promising.

A specially adapted machine ADAM-1 for the thermoluminescence fine grain dating of bricks was constructed in an interdisciplinary research project, undertaken by a team recruited from three faculties ...of the Czech Technical University in Prague. This TL-reader is able to measure and evaluate automatically numerous samples. The sample holder has 60 sample positions, which allow the irradiation and evaluation of samples taken from two locations. All procedures of alpha and beta irradiation by varying doses and the TL-signal measurement as also the age evaluation and error assessment are programmable and fully automated.
Results of studies of radiation damage to photocouplers are presented with the aim of determining their capabilities for radiation monitoring. Response in the 60Co gamma ray field and the 252Cf ...fission neutron field was measured and the contribution of various components of photocouplers to radiation damage was determined. The main contributor to the current-transfer ratio degradation was found in the amount of LED light output of the photocoupler. However, the contribution of other components, phototransistor and light guide, is also not negligible. A use was found for dose measurement in the range of hundreds of Gy to kGy for gamma and tenths of a Gy to Gy for fast neutrons.
The DIRAC experiment at CERN has achieved a sizeable production of Ie super(+Ie) super(-) atoms and has significantly improved the precision on its lifetime determination. From a sample of 21 227 ...atomic pairs, a 4% measurement of the S-wave IeIe scattering length difference inline image has been attained, providing an important test of Chiral Perturbation Theory.

High-dose Solu-Medrol (Upjohn, Kalamazoo, Mich) therapy has become standard care in the management of acute spinal cord injury (ASCI). This study attempts to define the adverse effects that ...Solu-Medrol therapy has on these patients.
Retrospective review with historical control.
From May 1990 to April 1994, all patients with ASCI admitted within 8 hours of injury received high-dose Solu-Medrol per the National Acute Spinal Injury Study (NASCIS-2) protocol. Their demographic and outcome parameters were compared with those of a group admitted from March 1986 to December 1993 with an associated ASCI who received no steroid therapy.
Steroid therapy was associated with a 2.6-fold increase in the incidence of pneumonia and an increase in ventilated and intensive care days. However, it was associated with a decrease in duration of rehabilitation and had no significant impact on other outcome parameters, including mortality.
Although the NASCIS-2 protocol may promote early infectious complications, it has no adverse impact on long-term outcome in patients with ASCIs.
