[Chronic radiculopathy. Use of minimally invasive percutaneous epidural neurolysis according to Racz].

Treatment of chronic low back pain exhibiting radicular symptoms poses a clinical problem that has not yet been solved. The technique of percutaneous minimally invasive neurolysis described by Racz is being performed increasingly to treat chronic radiculopathy. A total of 61 patients with corresponding symptomatology after screening for inclusion and exclusion criteria in the region of the lumbar spinal nerve were treated with the Racz catheter technique. Distinct clinical improvement was observed at the 3- and 6-month follow-ups after percutaneous minimally invasive epidural neurolysis. Subjective pain perception, quantified by the McNab score, clearly improved after 3 as well as 6 months. With the exception of partial catheter shearing in two cases and one occurrence of infection, no relevant side effects were noted. The Racz catheter technique for treatment of chronic radiculopathy following disk surgery is suitable with minimal side effects.

[Leading symptom elbow pain. Differential diagnosis].

Pain affecting the elbow joint may be caused by a number of different pathologies. In principle, these can be grouped by causality criteria into degenerative causes, inflammatory causes, tumor disease, congenital disease and the sequelae of trauma. The majority of these latter are associated with typical clinical symptoms that can be established with the aid of a systematic clinical examination, history-taking, inspection, palpation, an examination of joint mobility, and finally radiography. In this way, the diagnosis can rapidly be established.

Stress and strain of short haul bus drivers: psychophysiology as a design oriented method for analysis.

Psychophysiological measures offer objective information for workplace design according to user requirements. They are, however, rarely applied in industrial practice due to weak points from the designer's point of view, such as the differentiation of various superimposed stressors, inter-individual differences, and the effort required for data acquisition and handling. In this study a set of psychophysiological methods was used to analyse bus driver workplaces as a basis for redesign, and afterwards to evaluate design improvements. During inner-city operation bus drivers are exposed to a particular workload situation, especially due to the high density of traffic and bus stops. Their job is characterized by highly frequent and often simultaneous task execution, performed with a compulsory body posture and under exposure to vibration and noise. To reduce the workload related to the equipment and tasks of bus driving, a research project was initiated to design a new driver workplace that meets the specific ergonomic requirements of the drivers. A detailed workload analysis, consisting of a task analysis, a strain analysis derived from ECG measures and an eye movement analysis was performed during public bus driving in different cities and with different drivers and bus types. Although the results have to be considered as somewhat limited owing to the methodological restraints and conditions of a field study, they provided valuable guidance for design. A new concept for the driver cabin was created based on this database. After installation, this design was evaluated by similar psychophysiological measures. Comparison of the pre- and post results indicates that the redesigned work station reduced workload levels.

Virtual reality arthroscopy training simulator.

This paper describes the result of the interdisciplinary cooperation of traumatologists of the Berufsgenossenschaftliche Unfallklinik (BGU) in Frankfurt am Main and a team of computer graphics scientists of the Franunhofer Institute for Computer Graphics in Darmstadt. We have developed a highly interactive training simulator system by means of computer graphics and virtual reality techniques.

Intraluminal cyclosporine A reduces capsular thickness around silicone implants in rats.

One theory of the cause of connective tissue capsule formation around silicone mammary prostheses is based on an immunological interaction. In an in vitro pilot study, it is shown that intraluminal cyclosporine A, a potent T-lymphocyte-specific immunosuppressive agent, can diffuse slowly through the outer shell of a standard double-lumen silicone breast implant. Round silicone tissue expanders containing 50 mg of cyclosporine A were implanted subcutaneously in 10 rats. Ten animals served as controls. Evaluation was performed after three months. A significant decrease in collagen capsular thickness of 21.6 +/- 5.4 microns (mean +/- standard deviation was measured histomorphometrically in the treated group compared with 39.6 +/- 8.6 microns in the control group (p less than 0.001).

Investigation of potential interaction of ciprofloxacin with cyclosporine in bone marrow transplant recipients.

The effect of the 4-quinolone antimicrobial agent ciprofloxacin on the concentration in plasma and the pharmacokinetics of the immunosuppressive agent cyclosporine was studied in 10 bone marrow transplant recipients. There were no statistically or clinically significant changes in cyclosporine trough concentrations or areas under the concentration-time curve following oral doses of 500 mg of ciprofloxacin every 12 h for 4 days. The data suggest a lack of relevant pharmacokinetic interaction of ciprofloxacin with cyclosporine. There was no indication of an enhanced nephrotoxicity for this drug combination.

[Endemic situation of leprosy in the municipality of Rondonopolis-Mato Grosso].

Here we show a report about the incidence of leprosy in Rondonópolis, State of Mato Grosso in Brazil. We direct attention to the fact that the contemporary index of prevalence in Brazil doesn't correspond to our reality when one makes a program of dynamic research of new cases and clearances to the population, medical staff and co-workers, through lectures and programs on radio and television, besides articles in local papers.

[On the importance of the steam trap to the efficient sterilization of solutions in stored blood bottles by saturated steam under pressure (author's transl)].

Biological tests with soil samples were performed to fix the sterilization time for a new steam sterilizer. These tests yielded repeatedly positive spore findings despite modifications of the conditions of sterilization. Having excluded a series of possible sources of trouble, the authors stated that the quality of the steam was the assignable cause. After restoration of the functionality of the steam traps, the biological tests yielded negative results also under normal conditions of sterilization.
