    Description / Table of Contents: Zusammenfassung Blutrückstand, Clearance, Effektivität und Handhabung der HFAK Typ 4 werden im Routinebetrieb eines Dialysezentrums einmal a) bei nicht entgastem Dialysat und Heparinisierung am Anfang der Dialyse sowie b) bei entgastem Dialysat und einer systemischen Heparinisierung ca. 5 min vor Dialysebeginn geprüft. Bei Versuchsbedingung A werden im Mittel 17,9 ± 12,9 ml Blutrückstand gefunden. Das entspricht einem Volumen von ca. 18% des Blutkompartments der HFAK 4. Bei Versuchsbedingung B wurde ein mittlerer Blutrückstand von 6,3 ± 2,8 ml gefunden, was 6% des Blutkompartments ausmacht. Dementsprechend war die Effektivität bei Versuchsanordnung A um 12% geringer als bei B. Die Clearancewerte für Kreatinin lagen bei einem Blutdurchfluß von 200 ml/min bei 114 und für Harnstoff bei 146 ml/min. Die Handhabung im klinischen Routinebetrieb ist komplizierter als bei vergleichbaren Einmaldialysatoren. Bei sorgfältiger Einhaltung einer systemischen Heparinisierung vor Dialysebeginn und einer effektiven Dialysatentgasung bietet die neue HFAK 4 Vorteile gegenüber den herkömmlichen Einmaldialysatoren.
    Notes: Summary Residual blood volume, clearance and effectivity of the Hollow Fiber Artificial Kidney 4 (HFAK 4) was studied by labelling red blood cells by 51-Cr in 84 routine dialyses under two conditions: a) with not deaerated dialysat and start of heparinisation at the beginning of the dialysis b) with deaerated dialysat and systemic heparinisation 5 minutes before beginning of the dialysis. Under condition (a) we obtained a mean of 17.9 ± 12.9 ml residual blood in the HFAK 4. This corresponds to 18% of the whole priming volume. Under condition (b) we measured a residual blood volumen of 6.3 ± 2.8 ml, which is 6% of the priming volumen. Consecutively the effectivity under condition (a) was 12% less than in (b). The clearances of creatinin, BUN and uric acid were higher in comparison to other dialysers at the exception of the Meltec Multipoint (1 m2) Kiil.

    Description / Table of Contents: Zusammenfassung Im Kopf-Halsbereich stellt die szintigraphische Erfassung maligner Tumoren und deren Metastasen eine gute Bereicherung der diagnostischen Möglichkeiten dar. Zur Untersuchung eignen sich solche Substanzen, die eine hohe Tomoraffinität besitzen und sich gut radioaktiv markieren lassen. Aus diesem Grund wurde für die vorliegenden Untersuchungen das Zytostatikum Bleomycin benutzt und mit57Cobalt markiert. Die szintigraphische Untersuchung erfolgte 4–6 Std nach intravenöser Applikation von 1 mCi57Co-Bleomycin mit Hilfe der Gamma-Kamera. 60 Patienten mit verschiedenen neoplastischen Erkrankungen wurden untersucht, 46 hatten tumoröse Veränderungen im Kopf-Hals-Bereich, die übrigen im Thorax-Abdomen. Von den unbehandelten Kopf-Hals-Malignomen konnten 34 (85%) szintigraphisch nachgewiesen werden; 21 (81%) waren epithelialen und 13 (69%) mesenchymalen Ursprungs. Die Möglichkeiten der Untersuchungsmethode werden dargestellt; ihre klinische Bedeutung besteht im Nachweis von Primärtumoren und deren Metastasen, von Rezidiven und Tumorresten sowie in der Lokalisationsdiagnostik von Fernmetastasen.
    Notes: Summary Tumorscanning of malignomas and their metastatic nodules in head and neck is an enrichment of diagnostic possibilities. For the examination such substances can be used, which are tumoraffine and well to mark with a radio-isotope. Therefore we have marked the cytostatic drug Bleomycine with57Co. Scans were performed with the Anger-Camera 4 to 6 hrs after intravenous injection of 1 mCi57Co-Bleomycine. 60 patients with different malignomas have been examined, 46 with tumor-localization in head and neck, the others in thoraxabdomen. 34 (85%) of the head and neck malignomas could be demonstrated; 21 (81%) were squamous cell carcinomas, 13 (69%) sarcomas. The possibilities of this method are shown; its clinical importance lies in the identification of primary tumors and their metastatic nodules, of relapses and tumorrests as well as the localization of distant metastasises.

    Notes: Abstract Three cases of symptomatic neuralgia of the trigeminal nerve due to an amyloidoma in the gasserian ganglion are described. The correct diagnosis was not made prior to histological examination of the surgical biopsy specimens. Medical history and clinical observation led to the diagnosis of a malignant process of the nasal cavities in the first patient; of an inflammatory dental focus in the second patient; and of multiple sclerosis in the third patient. CT findings were normal in cases 1 and 2; in case 3, a schwannoma was suspected from the CT appearances. In case 1, MRI had not been performed; in cases 2 and 3, MRI revealed a tumour mass which was also considered to be a schwannoma. Histologically, the tumours consisted of masses of amyloid deposits which had largely replaced the pre-existing ganglionic cells and satellite cells. Electron microscopy confirmed the fibrillar structure of the deposits. Immunohistochemistry and immunocytochemistry revealed the amyloid to belong to the AL-lambda subtype.

    Notes: Summary The scanning of tumors and their metastasises today means an enrichment of diagnostic possibilities—especially in the head and neck area. So far various radiopharmaceuticals have been used for this examination but the results have only been good with a few of them. We habe marked the cytostatic drug Bleomycine with radioactive 57Co to get a high tumor-specific concentration. On a great number of patients own experiences with the scintigraphic diagnostic for localization using this radiopharmaceutical are reported. Over 85% of the squamous cell carcinomas and over 70% of the sarcomas of head and neck can be demonstrated. The possibilities of this examination, the clinical importance and indication for therapy is shown and discussed on the own cases.

    Notes: Summary Between Nov. 1985 and Nov. 1988, sixty-three patients with high grade malignant (hg) and intermediate grade malignant (img) Non Hodgkin's Lymphoma (NHL) were treated with MACOP-B (methotrexate, doborubicin, cyclophosphamide, vincristine, prednison and bleomycin). Thirty-seven patients received MACOP-B as an upfront treatment modality, whereas twenty-six patients had relapsed disease and received MACOP-B as a salvage protocol. Four weeks after termination of therapy, 75% of patients with de novo NHL and 72% of the patients with relapsed NHL were in complete remission (CR). In the group of newly diagnosed NHL, 22% achieved partial remission (PR) and 3% no change (NC), whereas in the group with relapsed disease 14% had PR and 14% had progressive disease (PD). At a medium follow-up of 12 months (range 1 month to 33 months), 74% of patients with de novo NHL continued to be in CR whereas the continuous CR rate in patients with relapsed disease was 35%. Overall survival after 30 months of observation for the patient group with de novo NHL was 75% and 40% for patients with relapsed NHL. The mean duration for completion of the projected 12 chemotherapy cycles, given in weekly intervals, was 12.9 and 13.5 weeks in upfront or salvage therapy, respectively. With low incidence of major toxicities, application of drugs on an outpatient basis, and high efficacy, MACOP-B shows substantial advantges for therapy of de novo and relapsed NHL.

    Notes: Abstract  High-dose chemotherapy with autologous transplantation of in vivo purged PBSC is a novel investigational approach to treating chronic myelogenous leukemia (CML) patients not responsive to conventional therapy with interferon-α (IFN-α) and not eligible for allogeneic transplantation. PBSC mobilization using either '5+2/7+3'-type chemotherapy or 'mini-ICE/ICE' chemotherapy was investigated in 43 patients with advanced phases of Philadelphia (Ph)-positive CML. Thirty patients were in late chronic phase (〉12 months post diagnosis) and 13 patients in accelerated phase (AP) or blast crisis (BC). Contamination with Ph-positive cells was evaluated in harvests from 37/43 patients. The outcome of PBSC mobilization was dependent on the type of chemotherapy administered: a complete or major cytogenetic response (〈35% Ph-positive metaphases) in leukapheresis collections was obtained in ten of 15 patients treated with 'mini-ICE/ICE' but in only three of 28 patients treated with '5+2/7+3' chemotherapy. One patient (1/43) in blast crisis died during mobilization therapy (2%). Twenty-five patients underwent PBSC transplantation and all of them engrafted successfully. Transplantation-related mortality was 0%. The data show that in advanced phases of CML the chance of harvesting Ph-negative peripheral blood stem cells depends on the type of chemotherapy used for mobilization.
