    Notes: Summary Substitution of insulin for a dietary regime with or without oral hypoglycaemic agents prior to operation is, despite its general use, often not satisfactory because of lack of time and leads frequently to hypoglycaemia and sometimes to excessive insulin-antibody production. We therefore administered 1.0 g of Tolbutamidei.v. together with at least 100 g of carbohydrates per day to 36 non-insulin dependent diabetic patients, and compared the results with those of 28 similiar cases switched to insulin preoperatively in the usual way (I), and those of 27 patients receiving insulin before, during and after the operation (II). Interventions in the group on Tolbutamide i.v. (III) were more severe and lasted longer than those in the control groups. Blood-sugar levels on the operation day rose to 209 ± 76 mg% in the Tolbutamide group, (Control group I 203 ± 57, II 186 ± 52). Hypoglycaemia was observed in the control groups only. The method proposed avoids unnecessary insulin treatment and its consequences, and can be recommended, with correct selection of patients, for further evaluation during minor and more extensive operations.

    Description / Table of Contents: Abstract Objective: This study was designed to investigate the differences between TIVA with propofol/remifentanil (P/R) and balanced anaesthesia with sevoflurane/fentanyl (S/F) in gynaecological laparoscopic surgery. Emphasis was put on haemodynamic reaction, recovery profile, postoperative side effects and patient satisfaction. Methods: Sixty patients were randomly assigned to receive either total intravenous anaesthesia with propofol/remifentanil or anaesthesia with sevoflurane/fentanyl. After premedication (midazolam) and induction of anesthesia (propofol, atracurium) in both groups, either 1 µg/kg fentanyl (S/F) or 1 µg/kg remifentanil (P/R) was injected. Anaesthesia was maintained with 0.5 µg/kg/min remifentanil (reduced to 50% after 5 min) and 0.06 µg/kg/min propofol (P/R) or 1.7 vol % sevoflurane (S/F). Both groups were mechanically ventilated with 30% oxygen in air. The administration of sevoflurane and the infusion of the anaesthetics were adjusted to maintain a surgical depth of anaesthesia. For postoperative analgesia 1 g paracetamol was administered rectally prior to surgery. After recovery 20 mg/kg metamizol was given intravenously. At the end of surgery the anaesthetics were discontinued and haemodynamics, early emergence from anaesthesia, pain level, frequency of analgesic demand, incidence of PONV, shivering and patient satisfaction were assessed. Parameters were recorded for 24 h postoperatively. Results: Recovery time after propofol-remifentanil anaesthesia was significantly shorter than after administration of sevoflurane and fentanyl (spontaneous ventilation 4.1 vs. 6.3 min, extubation 4.3 vs. 9.3 min, eye opening 4.4 vs 8.2 min, stating name 5.3 vs. 13.2 min, stating date of birth 5.4 vs. 13.3 min). There were no significant differences between the groups in shivering, pain score, analgesic demand and PONV. The S/F group responded to tracheal intubation with significantly higher blood pressure than the P/R group. During maintenance of anaesthesia heart rate in patients with S/F was significantly higher (P/R: HR max +16/–10; S/F: HR max +24/–0.). Measured on a scale from very satisfied to very dissatisfied, 73% of the patients in the P/R group were ”very satisfied” (S/F 23%) and 23% were ”satisfied” (S/F 62%). Conclusion: Compared with patients given balanced anaesthesia with sevoflurane and fentanyl, TIVA with propofol and remifentanil proved to be particularly suited for gynaecological laparoscopic surgery. Its major advantages are haemodynamic stability, significantly shorter times of emergence, and the exceptional acceptance by the patients.
    Notes: Zusammenfassung Fragestellung: Unterscheidet sich eine TIVA mit Remifentanil/Propofol (P/R) von einer balancierten Anästhesie mit Sevofluran/Fentanyl (S/F) hinsichtlich der Hämodynamik, des Aufwachverhaltens, postoperativer Nebenwirkungen und der Patientenzufriedenheit? Methodik: 60 Patientinnen wurden randomisiert einer Anästhesie mit (P/R) oder (S/F) zugeteilt. Nach oraler Prämedikation mit Midazolam wurde die Narkose mit Propofol eingeleitet, die Relaxierung erfolgte mit Atracurium. Gemäß randomisierter Gruppenzuteilung wurde 1 µg/kg Fentanyl oder 1 µg/kg Remifentanil i.v. injiziert und die Narkose bis zum OP-Ende entweder mit 0,5 µg/kg/h Remifentanil (Reduktion auf 50% nach 5 min) und mit 0,06 mg/kg/min Propofol oder mit 1,7 Vol.-% Sevofluran aufrechterhalten. Beide Gruppen wurden mit 30% O2 in Luft beatmet. Die Dosierung von Sevofluran, Propofol und Remifentanil wurden bei Bedarf der jeweiligen Intensität chirurgischer Stimuli angepaßt. Zur postoperativen Analgesie erhielten alle Patientinnen zu OP-Beginn 1 g Paracetamol rektal, nach Erwachen Metamizol 20 mg/kg i.v.. Bei OP-Ende wurde die Anästhetikazufuhr unterbrochen und folgende Parameter erfaßt: mittlerer arterieller Blutdruck, Herzfrequenz, Aufwachverhalten, Schmerzintensität, Analgetikabedarf, PONV, Muskelzittern und die Patientenzufriedenheit mit dem Anästhesieverfahren. Der Beobachtungszeitraum betrug 24 h. Ergebnisse: Die Patientinnen waren nach einer P/R Narkose signifikant eher wach und orientiert als nach einer Anästhesie mit S/F (Spontanatmung 4,1 vs. 6,3 min, Extubation 4,3 vs. 9,3 min, Augenöffnen 4,4 vs. 8,2 min, Namen nennen 5,3 vs. 13,2 min, Geburtsdatum 5,4 vs. 13,3 min). Die Inzidenz von PONV (43% vs. 43%) und Muskelzittern (56% vs. 37%) sowie die Schmerzintensität und die Anzahl der Schmerzmittelanforderungen (67 vs. 52) waren in beiden Gruppen vergleichbar. Der MAP war in der S/F-Gruppe nach der Intubation signifikant höher, die HF im gesamten Verlauf signifikant höher als in der P/R Gruppe (P/R: HF max. +16/–10; S/F: HF max. +24/–0). Auf einer Skala von „sehr zufrieden–sehr unzufrieden” waren 73% (P/R) der Patientinnen mit dem Anästhesieverfahren „sehr zufrieden” (S/F 23%), 23% „zufrieden” (S/F 62%). Schlußfolgerung: Verglichen mit einer balancierten Anästhesie mit Sevofluran und Fentanyl erwies sich die TIVA mit Remifentanil und Propofol als besonders vorteilhaft für laparoskopische Operationen in der Gynäkologie. Wesentliche Vorteile waren signifikant schnellere Aufwachzeiten, die hämodynamische Stabilität und die große Akzeptanz des Anästhesieverfahrens durch die Patientinnen.

    Description / Table of Contents: Summary The mean cortisol secretion rate was significantly elevated in fifteen patients with acromegaly. The increase was especially pronounced in untreated patients while in treated ones the mean value was close to that of normal persons. Calculated as secretion rate per kg body weight there was also a significant elevation in patients with untreated acromegaly. Conversely, in treated patients the value was in the low normal range. In four patients with active acromegaly the cortisol secretion rate per kg body weight was significantly higher than in those with an inactive, untreated pituitary process. The corticosterone secretion rate in nine investigated patients with acromegaly was also significantly increased, both in absolute terms and expressed per kg body weight.
    Notes: Zusammenfassung Die mittlere Cortisolsekretion war bei 15 Akromegaliepatienten signifikant erhöht. Die Steigerung war besonders ausgeprägt bei den unbehandelten Patienten, während sich der Mittelwert bei den behandelten dem der Normalpersonen annäherte. Bezogen auf das Körpergewicht fand sich bei den unbehandelten Akromegalen ebenfalls eine signifikant erhöhte Cortisolsekretion. Bei den behandelten lag sie dagegen im untersten Normbereich. Bei vier Patienten mit einer floriden Akromegalie ließ sich gegenüber denjenigen mit einem unbehandelten, inaktiven HVL-Prozeß eine signifikant erhöhte Cortisolsekretion pro kg Körpergewicht nachweisen. Die Corticosteronsekretion war bei neun untersuchten Patienten absolut und bezogen auf das Körpergewicht signifikant gesteigert.

    Description / Table of Contents: Summary Experiences with a New Test-strip for Bloodsugar Determination. Blood-sugar values were estimated in 643 in- and out-patients with the new test-strip “Haemo-Glucotest”. Blood-sugar determinations performed with the Auto-Analyzer (Hoffmann) served as an objective control. The treatment of out-patients was determined according to the values of the “Haemo-Glucotest” strip and before the Auto-Analyzer results arrived. 80% of the estimated values varied from the Auto-Analyzer results by less than ± 20 mg-%. Preliminary therapy had to be modified in only 6% of the patients. The precision of the determination depends upon illumination and the ability for color discrimination of the person working with the test-strip. The “Haemo-Glucotest” strip is not only suitable for detection of hyperglycemia and hypoglycemia, but also for control of therapy in diabetic out-patients.
    Notes: Zusammenfassung Der Teststreifen Hämo-Glucotest wurde an 643 stationär und ambulant behandelten Diabetikern erprobt. Als objektiver Vergleich dienten die Blutzuckerbestimmungen nachHoffmann im Autoanalyzer. Die Behandlung der ambulanten Patienten wurde nach den Ergebnissen des Hämo-Glucotest vor Kenntnis der Autoanalyzerbestimmung festgelegt. 80% der geschätzten Werte wichen um weniger als ± 20 mg-% von den durch Autoanalyzer bestimmten Blutzuckerwerten ab. Die nach den Testergebnissen vorläufig festgelegte Therapie der ambulanten Patienten brauchte nur in 6% der Fälle korrigiert zu werden. Die Genauigkeit der Bestimmung ist von den Beleuchtungsverhältnissen während des Tests und vom Farbunterscheidungsvermögen des Untersuchers abhängig. Der Teststreifen eignet sich nicht nur zur Erfassung von Hypo- und Hyperglykämien, sondern auch für eine orientierende Blutzuckerbestimmung bei der ambulanten Einstellungskontrolle von Diabetikern.

    Notes: Abstract Low-voltage-activated (1-v-a) and high-voltage-activated (h-v-a) Ca2+ currents I Ca were recorded in whole-cell voltage clamped NG108-15 neuroblastoma x glioma hybrid cells. We studied the effects of arachidonic acid (AA), oleic acid, myristic acid and of the positively charged compounds tetradecyltrimethyl-ammonium (C14TMA) and sphingosine. At pulse potentials 〉−20 mV, AA (25-100 μm) decreased 1-v-a and h-v-a I Ca equally. The decrease developed slowly and became continually stronger with increasing time of application. It was accompanied by a small negative shift and a slight flattening of the activation and inactivation curves of the 1-v-a I Ca. The shift of the activation curve manifested itself in a small increase of 1-v-a I Ca at pulse potentials 〈−30 mV. The effects were only partly reversible. The AA effect was not prevented by 50 μm 5, 8, 11, 14-eicosatetraynoic acid, an inhibitor of the AA metabolism, and not mimicked by 0.1–1 μm phorbol 12, 13-dibutyrate, an activator of protein kinase C. Probably, AA directly affects the channel protein or its lipid environment. Oleic and myristic acid acted similarly to AA but were much less effective. The positively charged compounds C14TMA and sphingosine had a different effect: They shifted the activation curve of 1-v-a I Ca in the positive direction and suppressed 1-v-a more than h-v-a I Ca; their effect reached a steady-state within 5–10 min and was readily reversible. C14TMA blocked 1-v-a I Ca with an IC50 of 4.2 μm while sphingosine was less potent.

    Notes: Abstract With an increasing number of new vaccines available for routine childhood immunization, combination vaccines are needed in order to maintain or achieve a high compliance with recommended immunization programmes. In a prospective, randomized, comparative, multi-centre study, 822 healthy infants were enrolled to receive three doses of either a candidate or a commercially available Haemophilus influenzae type b (Hib) vaccine concomitantly with diphtheria-, tetanus- acellular pertussis (DTaP) vaccine. Study subjects were randomly allocated to one of the following groups: (1) separate, or (2) mixed injection of DTaP and candidate Hib vaccine, or (3) separate injection of DTaP and commercial Hib vaccine. One year later the first 189 study subjects received either separate or mixed injections of the same Hib and DTaP vaccines as booster doses. Evaluation of reactogenicity was based on diary cards completed by parents. Immunogenicity was documented by measuring IgG antibody concentrations in serum samples taken before and 4 weeks after primary and booster vaccination. No serious adverse events occurred and most local and systemic reactions were mild to moderate. Booster doses were more reactogenic than primary doses with all groups. Antibody concentrations against pertussis antigens were similar to those seen with DTaP alone. All but one subject had protective antibody concentrations against diphtheria and tetanus. Primary immune response to the Hib vaccine was significantly lower in the group receiving the mixed Hib-DTaP vaccine, however, ≥95% of vaccinees had anti-Hib antibody concentrations ≥0.15 μg/ml and there was a marked booster response (〉100-fold) in all groups. Conclusions Mixing DTaP and Hib vaccines for primary immunization caused a decrease in anti-Hib antibody response, although after primary immunization as after booster doses, all subjects showed antibody concentrations considered to be protective for invasive Hib disease. Mixing of the vaccines did not result in increased reactogenicity.

    Notes: Abstract The objective of this study was to compare the spread of pertussis in children and adults being secondary contacts after household exposure. The study was nested in an efficacy trial of an acellular pertussis vaccine. The spread of the disease was also monitored with respect to gender and antibiotic therapy. A total of 453 index cases, of which 133 were monitored for adult disease, fulfilled the WHO definition of pertussis. They had contacts to 173 unvaccinated children aged 6–47 months, and a total of 101 adults with pertussis were followed. Detection of the bacteria, or a significant increase of specific antibodies confirmed the diagnosis. Secondary spread of the disease was assumed, when a household member coughed for 7 days or more and had laboratory evidence for pertussis. Crude attack rates (AR) were 69% in children and 31% in adults (P 〈 0.05). AR in children were independent of gender but more women than men (P = 0.02) were affected in those households where the index case was a child. Erythromycin treatment of the index case reduced the AR in exposed toddlers from 80% to 57% (P = 0.06), and in exposed adults from 40% to 21% (P= 0.2). Erythromycin therapy in contacts did not alter the clinical course of the disease significantly. Conclusions In a household study of pertussis, 69% of children and 31% of adults (more women than men) contracted the disease. Erythromycin reduced the number of infections in household contacts, but did not alter the clinical course in those who contracted pertussis.

    Notes: Abstract Acellular pertussis vaccines are less reactogenic than whole cell pertussis vaccines, but they are also more expensive. Based on simulation models, we compared the costs and effects of three alternative pertussis vaccination strategies in German children to ”no prevention”: (1) vaccination with whole-cell vaccine at 45% coverage (vaccine efficacy 90%), (2) vaccination with acellular vaccine at 45% coverage (vaccine efficacy 85%), and (3) vaccination with acellular vaccine at 90% coverage. In the two low coverage scenarios expected annual savings in direct medical costs through prevention of disease were larger for whole-cell than for acellular vaccination (252 vs 216 million DM, respectively). Direct costs for treating the more important adverse events induced by whole-cell vaccination (16.9 million DM annually) did not outweigh the higher direct costs of pertussis infections not prevented with the acellular vaccine and the higher price of the acellular vaccine. However, vaccination with acellular pertussis vaccine rapidly becomes as cost saving as vaccination with whole-cell vaccine as soon as vaccination coverage can be raised from 45% to 52.5% with acellular vaccine. Acellular vaccination is also the superior alternative when considering indirect cost savings resulting from reduction in work-loss due to adverse events. Conclusion In our simulations, the most cost-effective pertussis prevention strategy was the use of an effective whole-cell vaccine with a high coverage rate. Introduction of the more expensive acellular pertussis vaccines becomes cost saving if at least a 7.5% increase in coverage is achieved. If also non-medical indirect costs to parents resulting from vaccine associated side-effects are accounted for, acellular vaccines may be more cost-effective also in countries with already high whole-cell vaccine coverage.

    Notes: Abstract  The lack of an adequate immune response to the major polysaccharide of the Haemophilus influenzae type b (Hib) capsule (polyribosyl ribitol phosphate) (PRP) in very young infants (〈 18 months) can be overcome by conjugating PRP to a T-cell dependent carrier protein. We studied whether administration of a tetanus-PRP conjugate vaccine reconstituted with a diphtheria-tetanus-acellular pertussis-hepatitis B (DTPa-HBV) vaccine as a three dose primary course at 3, 4 and 5 months of age induced PRP-specific immunological memory, by examining the anti-PRP response to a dose of unconjugated PRP given with the DTPa-HBV booster approximately 1 year later. The unconjugated PRP elicited protective anti-PRP antibody levels (≥ 0.15 μg/ml) in all but 3 of the 369 vaccinees, including 13 infants who failed to demonstrate a measurable immune response after the primary course. In a sub-cohort of 54 subjects all had anti-PRP levels ≥ 0.5 μg/ml within 7–14 days of the booster showing a rapid anamnestic type response. Both primary and booster responses were predominantly IgG1 indicating a T-cell dependent response. The DTPa-HBV components elicited protective anti-diphtheria, anti-tetanus and anti-HBs antibody levels in ≥ 98.5% of vaccinees, and immune responses to each of the acellular pertussis vaccine components in 92.3%–97.3% of subjects. Conclusion The tetanus-PRP conjugate vaccine not only elicited a good primary humoral response, but also induced immunological memory so that the infants were able to mount a large and rapid immune response to subsequent exposure to plain PRP, indicating that protection against circulating wild-type Hib had been generated. Successful induction of immunological memory occurred even when there was no measurable humoral anti-PRP response to the primary course. Tetanus-PRP conjugate vaccine can be used in combination with DTPa-HBV vaccine, when administered separately or as a single injection in the same syringe, in primary immunisation schedules at 3, 4 and 5 months of age.
