Zusammenfassung
Bei einer 71j?hrigen Frau trat nach R?ntgenweichstrahltherapie an der Nase (Gesamtdosis 28 Gy, Gewebehalbwerttiefe 10,5–11,5
mm) eine ausgepr?gte Strahlenerosion auf. Diese zeigte 5 Wochen nach Ende der Bestrahlung noch keine Tendenz zur Abheilung.
Ursache dieses ungew?hnlichen Verlaufes war ein gleichzeitig bestehender Pemphigus vulgaris. Dieser hatte sich nach der Strahlentherapie,
vermutlich als Folge einer Freisetzung epidermaler Antigene, verschlimmert. Da? der Pemphigus in diesem Fall durch die Bestrahlung
ausgel?st wurde – wie mehrfach in der Literatur berichtet – ist unwahrscheinlich, aber nicht sicher auszuschlie?en.

Multiple structural and functional imaging modalities are available to localize the epileptogenic focus. In pre-surgical evaluation of children with pharmacoresistant epilepsy, investigations with the maximum yield should be considered in order to reduce the complexity of the workup. OBJECTIVE: To determine the extent to which PET, ictal/interictal SPECT and its co-registration with the patient's MRI contributes to correct localization of the epileptogenic focus, surgical intervention and to the post surgical outcome in paediatric patients. METHODS: The study population included children and adolescents with pharmacoresistant epilepsy (n = 50) who underwent preoperative evaluation, surgery and had postoperative follow-up for at least 12 months. Outcome was measured by postoperative seizure frequency using Engel's classification. RESULTS: Thirty-nine patients (78%) became completely seizure free after surgical intervention. The likelihood to benefit from surgical treatment was significantly higher if localization with more imaging modalities (MRI, PET, SPECT) were concordant with respect to the resected brain area (p < 0.01). Preoperative PET examination provided better localizing information in patients with extratemporal epilepsy and/or dysplastic lesions, whereas SPECT was found to be superior to PET in patients with temporal lobe epilepsy and/or tumors (p < 0.05). No significant difference was noted in the surgical outcome in younger or older age group, in children with or without special education needs. CONCLUSION: In paediatric epilepsy pre-surgical evaluation, the combined use of multiple functional imaging modalities for a precise localisation of the epileptogenic focus is worthwhile for both extratemporal and temporal lobe epilepsy, also when EEG and MRI alone are non-contributive, given the potential benefit of complete postoperative seizure control. 相似文献

We have measured the metabolic response to sequential administration of
propacetamol, metamizol and/or external cooling in 20 febrile patients
under sedation and analgesia and during mechanical ventilation. There was
no change in temperature (T degree) after propacetamol therapy, whereas
after metamizol only a small decrease was noted (from 38.9 (SEM 0.2) to
38.5 (0.3) degrees C; P = 0.02). External cooling produced a significant
decrease in T degree (39.1 (0.2) to 37.1 (0.2) degrees C; P < 0.0001)
accompanied by a decrease in energy expenditure (EE) (2034 (73) to 1791
(88) kcal day-1; P < 0.004). Heart rate and minute ventilation decreased
significantly in parallel. There were no other changes in haemodynamics or
pulmonary gas exchanges. We conclude that propacetamol and metamizol did
not produce a clinically significant decrease in T degree in febrile ICU
patients whereas external cooling decreased both T degree and EE. The
parallel decrease in body temperature and EE seemed to be related to opioid
administration or sedation, or both.

Fibers of three rigid-rod aromatic copolymers, produced by polycondensation of 2,2,6,6-tetraoxo-1,3,5,7-tetrahydro-2,6-dithia-s-indacene-4,8-diamine (DSDA), p-phenylenediamine and terephthaloyl dichloride, were spun from nematic solutions and characterized by wideangle X-ray-diffraction (WAXD) measurements and mechanical tests. A post-spin heat treatment was employed to improve the low degrees of orientation and crystallinity exhibited generally by the untreated fibers. The dominating crystal structures of the copolymers are similar to “modification I” of the well known fibers from poly(p-phenyleneterephthalamide) (PPTA). Thermally induced crosslinking of the fibers in the solid state was performed simultaneously with post-spin treatment. The influence of the annealing conditions on the mechanical fiber properties and the molecular order in the fibers was also investigated. All mechanical parameters were time-dependent, probably due to the generation of stable radicals during heat treatment. The radicals may give rise to chain scission. 相似文献

Objective: To study differences related to intensive care unit (ICU) structure and patient demography between the various countries
of Western Europe. Design: Application of data collected by the European Prevalence of Infection in Intensive Care (EPIC) study, a one-day prevalence
study. Setting: Voluntary participation of all Western European ICUs. A total of 1417 ICUs responded. Patients: All patients, older than 10 years of age, occupying a bed in the participating ICUs over a 24-h period. 10 038 patient case
reports were submitted. Results: The study revealed important differences. In particular, there seems to be a north/south divide with fewer ICU beds and more
severely ill patients in the south. The United Kingdom seemed more similar to southern European countries than to the north.
Conclusion: While there are similarities between European countries, large differences still remain and are important to identify to
enable us to work together to create a more uniform system of intensive care, which will in turn give more effective and efficient
patient care.

Our experiences with cobalt bleomycin scintigraphy in the treatment planning of ORL tumors are described. 142 scintigrams taken from 127 patients have been examined. As is shown by our investigation, cobalt bleomycin scintigraphy is a good examination method, however, too much expenditure is needed to have the necessary data for therapy planning. To our opinion, the information obtained in oto-rhino-laryngology by an exact clinical examination is as good as that of cobalt bleomycin scintigraphy. Our treatment schemes had only to be revised in some exceptional cases. 相似文献
