NOAH--A mobile emergency care system.

Experiencing communication problems in our emergency services, we developed an innovative communication network and system the NOAH-system (NOAH, which stands for Notfall -, Organisations - und Arbeitshilfe or Emergency-Organisation Active Aide System). In contrast with the currently established emergency services communication in Germany by radio wave, data is transferred from the scene in the form of an electronic record on a mobile computer by means of the wireless data communication network Modacom (Mobile Data Communication), which is provided by German Telekom. It is received at the dispatch-centre in mentioned format and transferred to the admitting hospital without any loss of data. - In a prospective study, the technical and conceptual suitability of this system was investigated. It was shown that an admitting hospital was informed more than 20 minutes in advance about the admittance of a patient. To assure the quality of transferred data, information was ranked by different criteria. This further demonstrated that much more precise information about a patient's condition was already available upon admittance in the hospital.

Surgical management of symptomatic spinal metastases. Postoperative outcome and quality of life.

STUDY DESIGN: Eighty-six surgical interventions in 76 consecutive patients with symptomatic spinal metastases were reviewed retrospectively. OBJECTIVES: To evaluate the postoperative outcome and quality of life of patients surgically treated for symptomatic spinal metastases. SUMMARY OF BACKGROUND DATA: The standard surgical treatment for patients with symptomatic spinal metastases is anterior spinal cord decompression with stabilization. However, because therapy is only palliative, satisfactory quality of life and high patient acceptance are essential. METHODS: The medical records of all patients were reviewed retrospectively. Furthermore, all surviving patients or the next of kin of deceased patients were interviewed by telephone, and the family doctors or the care-providing physicians of external institutions were contacted. RESULTS: First-choice surgical treatment was anterior spinal cord decompression with stabilization. Postoperative mean survival was 13.1 months, and mean time at home after spinal surgery was 11.1 months. Neurologic improvement with regard to Frankel classification was observed in 58% of the patients, and 93% were able to walk postoperatively. Pain relief was noted in 89%. Overall, 67% of the patients achieved moderate or good general health as shown by the Karnofsky Index, and 80% were satisfied or very satisfied with the surgical intervention. Moreover, 19% of the surgical interventions were associated with complications, local tumor recurrence developed in 22% of the patients, and paraplegia ultimately developed in 18% of patients. CONCLUSIONS: Surgical management of symptomatic spinal metastases, in particular anterior decompression, is of benefit in most metastatic lesions in terms of satisfactory postoperative outcome and quality of life. However, in patients with melanoma or lung carcinoma, the authors advocate spinal surgery only in very exceptional cases.

Fracture healing of the sheep tibia treated using a unilateral external fixator. Comparison of static and dynamic fixation.

It is generally accepted that when a fracture is treated with external fixation, dynamization of the fixation accelerates formation of the bony callus by transferring part of the functional loads. The aim of the research presented here was to validate this principle using in vivo measurements of callus stiffness. We created a transverse fracture in the mid third of the tibial shaft in 12 sheep and maintained a 3 mm gap between the fragments for 3 weeks. Two types of unilateral external fixators were applied. Axial loading was permitted (dynamization) from the fourth week onwards in 6 animals. In the other 6 animals, fixation remained static for both types of fixation. Weekly measurements of callus stiffness were obtained using a goniometer and load cell to assess bending stiffness. Two slightly different fixators were used. Callus formed in all 12 animals. Callus stiffness increased exponentially to reach the degree of stiffness measured on the contralateral side. There was no clear difference in healing between the two types of fixations nor between dynamic and static fixation. If a unilateral fixator was applied which did not maintain absolutely rigid fixation, the fracture generally healed well even without contact between the fragment ends. If the process of callus formation had begun normally, dynamic fixation offered no further benefit. Measuring the stiffness of the callus with an adequate measurement apparatus in vivo indicated that the fixator could be removed earlier than would have been authorized on the basis of radiological evidence alone.

[Telecommunication in trauma surgery. Communication networks of hospitals in East Bavaria].

The growing complexity of the performance processes in medicine makes it mandatory that the flow of information is faster and more consistent, especially when the sites of health care are far away from each other. The Regensburg model, a realization of lean telemedicine from a low-cost domain, using PC-based standard videoconferencing systems shows the use of modern telecommunications, especially in trauma surgery. In 203 prospectively evaluated teleconsultations between 15 participants a total of 697 images were transmitted via videoconferencing. In 95% of the trauma cases the transmitted material was judged as at least sufficient. In project-attending evaluations the efficacy of these systems and their use were clearly demonstrated. Savings in transportation costs of up to 4,400 DM per case were achieved. Through quicker flow of information quality improvements for all participants resulted; to some extent considerable costs for health care were avoided or reduced. Based on these thoughts, a new platform of communication will be established in Regensburg as a closed medical intranet for the region of eastern Bavaria.

[Percutaneous minimal invasive autologous spongiosa transplantation].

In eight patients with delayed union or nonunion after 3 degrees open fracture of the tibia, a minimally invasive technique of autologous bone grafting was performed. Bone harvesting from the iliac crest and debridement of the fracture side were done percutaneous by using a 5.5 mm acromionizer without complications. In seven of eight patients complete fracture healing could be achieved (88%). Percutaneous autologous bone grafting can be recommended on limited bone defects in patients with nonunion or delayed union of the tibia and severe soft tissue damage in the lower leg.

Algorithms for early management of pelvic fractures.

The successful management of pelvic fractures depends upon proper diagnosis and timely treatment. Severe pelvic fractures are life-threatening injuries in which a clear-cut treatment strategy is required to make decisions within the shortest possible time. An algorithm is presented in the form of a flow chart that has proven useful in facing difficult situations in the initial management of pelvic fractures. Decision-making is based on progressive clinical examination and a series of key questions. The sequence starts with the arrival of the patient, followed by the resuscitation phase, proceding through the initial examination and assessment of the patient to the final diagnosis and appropriate treatment. A safe approach to pelvic fractures is gained by following the proposed algorithm. The algorithm is an excellent teaching tool, but no guarantee can be given since every case is different and requires a specific approach.

[Rockwood capsulorrhaphy in shoulder instability. A clinical follow-up study].

Rockwood described a capsulorrhaphy technique for operative treatment of multidirectional shoulder instability with anterior dislocation. We have used this technique mainly in patients with severe multidirectional instability and now have 8 years' experience with it, which is reported below. The surgical technique involves refixation of the Bankart lesion with transosseous suture and double breasting of the anterior capsule. No transposition of the subcapularis muscle was performed. A functional rehabilitation program without immobilization was used in all patients. The daily activity level, the degree of discomfort upon shoulder-related activities and the subjective assessment of outcome were recorded for each patient. General outcome was determined with reference to Rowe's score. A clinical examination was performed as well as radiography. Strength was evaluated by standardized bilateral dynamometry. Follow-up examination was possible in 73 out of 82 patients. The mean age at follow up was 32.7 +/- 4.1 years, and the mean follow-up time, 4.3 years. The reason for surgery was recurrent dislocation in 81% of patients, pain in 4% and both pain and dislocation in 15% of patients. In 8 patients (10.9%) multiple (up to 4) previous surgical attempts by various methods had been unsuccessful. Postoperatively 59% (n = 44) were able to take part in sports without restrictions, 27.4% could take part only in sports not involving the shoulder, and 13.5% (n = 10) did not engage in any sports postoperatively. The redislocation rate was 12.3% (n = 9), and there was 1 traumatic redislocation. A deficit in abduction/elevation by 10-60 degrees was found in 4 patients (5.4%) and by > 60 degrees in 2 patients (2.7%).(ABSTRACT TRUNCATED AT 250 WORDS)

[Therapy of extensive lymphangioma of the vulva].

The lymphangioma of the vulva offers difficulties in differential diagnosis because of its wart-like appearance [7]. Is the diagnosis histologically confirmed, there often arise uncertainties about an adequate therapy [7, 2, 15]. By this case report these problems will be explained. Vaporisation with the CO2-Laser showed to be the predominant therapeutical procedure.

The immunomodulating effect of TP5 and indomethacin in burn-induced hypoimmunity.

Hypoimmunity after major trauma and thermal injury appears to predispose to septicemia. An increase of immune suppressive T cells and the inhibitory monocytes product PGE2 has been demonstrated postburn and are suggested as contributing to postburn hypoimmunity. TP5, the biologically active part of thymopoientin, has an immunomodulating effect on T cells. Indomethacin, an irreversible blocker of the prostaglandin synthesis has been suggested to reduce the inhibitory monocytes-mediated immunosuppression. In this study strains 2 and 13 guinea pigs received 20-30% TBSA scald burn and were subsequently injected with either TP5 or indomethacin or a combination of both on the 3 following days postburn. The ability of splenocytes to produce a secondary immune response to SRBC was measured in the in vitro AFC assay. The animals who had received TP5 and indomethacin showed significant improvement in their ability to mount an immune response in the AFC assay.
