    Notizen: Summary A second-look operation was performed on 151 patients with stage III and IV epithelial ovarian carcinoma who had responded to primary surgery and chemotherapy. 19% of the 79 patients who appeared clinically to be free of disease had microscopic recurrences and 23% had macroscopic residual disease at a second-look operation. The 5-year survival rate for patients with no histological and for those with microscopic secondaries at second-look operation were 55% and 35% respectively (P=0.45). Only patients with well or moderately well differentiated tumors and a small residual tumor mass at first operation had a good prognosis after a second-look operation even without further chemotherapy. Median survival after secondary debulking was 15 to 17 months and was independent in the radicality of the second-look procedure. Outside of clinical trials second-look laparotomy should therefore only be performed as a diagnostic procedured as a diagnostic procedure in patients with well or moderately well differentiated tumors who are left with a small residual tumor mass at the time of the first operation. Because this is a group of patients in whom chemotherapy can be discontinued after a negative second-look operation.

    Notizen: Summary On the basis of the results of earlier studies, 30 departments of gynecology have been cooperating nationwide in Austria since 1980 to promote the use of adjuvant chemotherapy after surgery for cure of ovarian carcinoma in early stages and the role of lymph node dissection and of second-look operation. Results recorded in more than 160 patients treated with adjuvant chemotherapy after so-called radical surgery performed in disease stages I and II demonstrate that only highly differentiated tumours in stage Ia can be cured by surgery only with no further adjuvant treatment. This underlines the necessity for staging. More than 200 patients with TNM stages III and IV were randomized after debulking surgery to receive treatment with different kinds of drug combinations to compare the therapeutic efficacy of a sequential alternating drug regimen consisting of Adriamycin-cisplatin+vincristine-cyclophosphamide+high-dose methotrexate with that of the combination of Adriamycin-cyclophosphamide and that of Adriamycin-cisplatin. High-dosed ifosfamide was also used in pilot studies.

    Notizen: Abstract Serum angiotensin converting enzyme (ACE) activity was determined in 46 children with congenital heart disease with normal and abnormal lung perfusion: (1) congenital heart disease with normal pulmonary blood flow (12 patients); (2) congenital heart disease with increased pulmonary blood flow (18 patients); (3) congenital heart disease with decreased pulmonary blood flow (16 patients). There was no significant difference in serum ACE activity between the three groups. In group 2 serum ACE activity had a tendency to correlate inversely with both mean pulmonary arterial pressure (r=−0.43;P≤0.05) and pulmonary vascular resistance (r=−0.48;P=0.05). No further correlations between serum ACE activity and age, serum electrolytes, creatinine nor other haemodynamic data could be established.

    Beschreibung / Inhaltsverzeichnis: Summary A second-look operation was perfomred on 171 patients with stage III and IV epithelial ovarian carcinoma who had responded to primary surgery and chemotherapy. 19% of the 89 patients who appeared clinically to be free of disease had microscopic recurrences and 23% had macroscopic residual disease at a second-look surgery. Only patients with well differentiated tumors and a small residual tumor mass at first operation had a good prognosis after a second-look operation even without further chemotherapy. Median survival after secondary debulking was 15 to 17 months and was independet in the radicality of the second-look procedure. Outside of clinical trials secondlook laparotomy should therefore only be performed as a diagnostic procedure in patients with well differentiated tumors who are left with a small residual tumor mass at the time of the first operation. In these patients chemotherapy can be discontinued after a negative second-look surgery. In all other patients with advanced epithelial ovarian carcinoma second-look-operation seems unnecessary. Second-look surgery might however still be of importance in the context of prospective randomized clinical trials.
    Notizen: Zusammenfassung Berichtet wird über 171 Patientinnen mit Ovarialkarzinom des Stadiums III und IV, bei welchen nach initialer Operation und Chemotherapie eine Second-Look-Operation durchgeführt wurde. Nach einer medianen followup Zeit von 44 Monaten zeigte sich in den einzelnen Gruppen folgendes Überleben: 1) Histologisch negativer Second-Look (n=55): mediane Überlebenszeit 66 Monate; 2) Mikroskopisch positiver Second-Look (n=20): medianes Überleben 46,5 Monate. 3) Sekundäre Tumorreduktion (n=48): 15,2–17,5 Monate medianes Überleben, unabhängig von der Radikalität des Tumordebulkings. 4) Patienten mit ausschließlicher Carcinosis peritonei (n=26): 17,3 Monate und 5) Inoperabilität wegen ausgedehnter Tumormassen (n=22): 5,1 Monat medianes Überleben. Unterteilt man die Patientinnen mit negativer Second-Look-Operation in eine “low-risk-Gruppe” (gut differenzierter Tumor, Resttumor bei Erst-Operation kleiner als 2 cm) und in eine “high-risk-Gruppe” (schlecht differenzierter Tumor, Resttumor bei Erst-Operation größer als 2 cm), so zeigt sich ein signifikant besseres Überleben (p〈0,02) in der “low-risk-Gruppe”, obwohl beide Gruppen zum Zeitpunkt der Second-Look-Operation histologisch tumorfrei waren. Es muß daher diskutiert werden, bei den sogenannten “high-risk-Patienten” die Chemotherapie bis zum Erreichen der tolerablen Toxizität chemotherapeutisch nachzubehandeln, um auf diese Weise die Überlebenszeiten zu verbessern. Eine Second-Look-Operation ist heutzutage noch im Rahmen von prospektiv randomisierten Studien notwendig, da derzeit noch keine andere Methode zur Verfügung steht, um das Ansprechen oder Nichtansprechen einer Chemotherapie optimal verifizieren zu können. Eine sekundäre Tumorreduktion bringt der Patientin mit Ovarialkarzinom keinen Überlebensbenefit; wird ein Resttumor nach Primärtherapie bereits klinisch festgestellt, so soll unter Umgehung der Second-Look-Operation sofort eine Second-Line-Chemotherapie eingeleitet werden.

    Notizen: Summary We present pharmacokinetic data of prolonged, intra-arterial indomethacin treatment (i.e. induction plus maintenance dose) for symptomatic patent ductus arteriosus (sPDA) in 26 ventilated premature infants. sPDA was assessed by two-dimensional and pulsed Doppler echocardiography. Permanent ductal closure occurred in 20 (76%) infants. Plasma levels of indomethacin were 1.18±0.74; 1.8±1.0; 1.51±0.93 and 1.25±0.98 μg/ml (mean±SD) at 12, 24, 48 and 72 h after initial dose administration. All except one patient who responded with ductal closure, showed plasma levels above 0.25 μg/ml throughout the 3 day treatment period and no case of sPDA reopening was noted. Although target concentrations over time were not defined, the data indicate that the maintenance levels measured were within the therapeutic range. A negative correlation was found for plasma drug levels and postnatal age (r=0.52;P〈0.01). Volume of drug distribution was 0.23±0.18l/kg, total clearance 0.1±0.11 ml/min and elimination constant 0.06±0.05h−1 (mean±SD). The great variation in pharmacokinetic data reflects the heterogeneity of the population studied with respect to extracellular fluid space, cardiovascular status, serum protein and other parameters.

    Notizen: Abstract In a case-control study in 398 neonates the value of measuring the levels of neutrophil elastase-alpha 1 proteinase inhibitor (EPI) for early diagnosis of neonatal infection was studied in comparison to the commonly used parameters of leukocyte count, ratio of immature to total granulocytes and C-reactive protein levels. Investigations were performed on day 1 or day 6 of life. On the basis of the clinical findings patients were allocated to one of the three following groups: healthy neonates (group A), neonates with local infections such as pneumonia or skin infection (group B) or neonates with septicemia as demonstrated by a positive blood culture (group C). The median EPI levels (with range) measured on day 1 were: group A 40 (15–65) µg/l, group B 120 (80–260) µg/l, group C 225 (140–355) µg/l. The levels on day 6 were: group A 27.5 (5–55) µg/l, group B 105 (65–370) µg/l, group C 182.5 (74–450) µg/l. EPI thus discriminated well between healthy neonates and neonates with infection, but not between neonates with infection and neonates with septicemia.
