    Notizen: Summary. Fetal transcutaneous carbon dioxide tension (tc-Pco), was monitored during 122 deliveries, using an electrode temperature of 44°C in 80 cases and of 41°C in 42 cases. Significant correlations between tc-Pco2 and umbilical artery blood Pco2 were found using both electrode temperatures, but the regression lines indicated a larger and more inconstant CO2-contribution from skin metabolism when the low electrode temperature was used. Normal range of tc-Pco2 was calculated at 41°C and 44°C electrode temperatures. Mean values of fetal tc-Pco2 were found to increase during normal labour, and especially in fetuses developing acidosis, but only four of six infants born with acidaemia had tc-Pco2 values exceeding the normal range.

    Notizen: Summary. The influence of electrode compression by the cervix on transcutaneous CO2 measurements (tc-Pco2) was studied during 20 deliveries by simultaneous measurements with two electrodes, one positioned under the cervical edge and the other free of the cervix. At a cervical dilatation of 〈8 cm, significantly higher values were measured by the electrode exposed to cervical compression, and tc-Pco2 fluctuations with uterine contractions were observed. This study confirms that the tonsure effect usually does not interfere with tc-Pco2 monitoring.

    Notizen: Summary. Simultaneous monitoring of fetal tissue pH (t-pH) and transcutaneous carbon dioxide (Tc-Pco2) was performed in 30 labours. Both t-pH and Te-Pco-2 at delivery were positively correlated with pH (r= 0·69) and Pco2(r= 0·68) of the umbilical artery blood. A tissue/transcutaneous standard base excess (t-SBE) was derived from the t-pH and the Tc-Pco2 and calculated for 13 fetuses a t delivery; there was a correlation with standard base excess of umbilical artery blood. An analysis of t-pH and Tc-Pco2 changes during the last hour of labour revealed that only infants who were born with decreased pH of the umbilical artery blood had decreasing t-SBE, while all others had a constant t-SBE.

    Notizen: Summary. Fetal transcutaneous carbon dioxide tension (tc-Pco2) was monitored simultaneously by two electrodes fixed with glue or suction during 10 deliveries. There were no differences in success rate, tc-Pco2 readings or stabilization time between the two fixation methods, but the glue fixation method was more time consuming, caused more discomfort to the patient and generally did not permit reapplication of the electrode.

    Notizen: Summary. Fifteen women were studied during the second stage of labour by measuring simultaneously fetal transcutaneous carbon dioxide tension (Tc Pco2 and maternal end-expiratory Pco2. A linear increase of Tc Pco2 with time was observed, predominantly because of changing maternal respiration patterns. The degree of maternal hyperventilation had no adverse effect on the status of the newborn infant.

    Notizen: Objective To test the postulated preventive effects of dietary n-3 fatty acids on pre-term delivery, intrauterine growth retardation, and pregnancy induced hypertension.Design In six multicentre trials, women with high risk pregnancies were randomly assigned to receive fish oil (Pikasol) or olive oil in identically-looking capsules from around 20 weeks (prophylactic trials) or 33 weeks (therapeutic trials) until delivery.Setting Nineteen hospitals in Europe.Samples Four prophylactic trials enrolled 232, 280, and 386 women who had experienced previous pre-term delivery, intrauterine growth retardation, or pregnancy induced hypertension respectively, and 579 with twin pregnancies. Two therapeutic trials enrolled 79 women with threatening pre-eclampsia and 63 with suspected intrauterine growth retardation.Interventions The fish oil provided 2.7 g and 6.1 g n-3 fatty acids/day in the prophylactic and therapeutic trials, respectively.Main outcome measures Preterm delivery, intrauterine growth retardation, pregnancy induced hypertension.Results Fish oil reduced recurrence risk of pre-term delivery from 33% to 21% (odds ratio 0.54 (95% CI 0.30 to 0.98)) but did not affect recurrence risks for the other outcomes (OR 1.26; 0.74 to 2.12 and 0.98; 0.63 to 1.53, respectively). In twin pregnancies, the risks for all three outcomes were similar in the two intervention arms (95% CI for the three odds ratios were 0.73 to 1.40, 0.90 to 1.52, and 0.83 to 2.32, respectively). The therapeutic trials detected no significant effects on pre-defined outcomes. In the combined trials, fish oil delayed spontaneous delivery (proportional hazards ratio 1.22; 1.07 to 1.39, P= 0.002).Conclusions Fish oil supplementation reduced the recurrence risk of pre-term delivery, but had no effect on pre-term delivery in twin pregnancies. Fish oil had no effect on intrauterine growth retardation and pregnancy induced hypertension, affecting neither recurrence risk nor risk in twin pregnancies.

    Notizen: [Auszug] SIR-Steven Dickman is correct to claim (Nature 348, 187; 1990) that university entrance standards in West Germany were generally relaxed in the 1960s, enabling more than a quarter of the age group concerned to attend university. This process has been welcomed by some and criticized by many others. ...

    Beschreibung / Inhaltsverzeichnis: Summary 60 consecutive fetal CTG-pH-registrations (cardiotocography with continuous pH registration) were analyzed in order to find the causes of the nonsuccessful tracings. Of the 60 tracings, 21 were of good quality, 16 partly successful, and 23 nonsuccessful. The monitoring for each patient had lasted for an average of 154 min with the range of 5–530 min. The quality of the pH recordings were not related to the duration of the pH observation, the maternal age and parity, or to the weight of the infant. If the electrode was applied too early (cervical orifice less than 5 cm) there was a greater risk of a nonsuccessful tracing. The drift of the electrode was less than 0.06 pH-units in 90% of the cases. The rate of nonsuccessful tracings is still too high and the difficulty in sterilization, calibration, and application of the electrode is still rather pronounced. At this moment the pH-electrode should be reserved for scientific use.
    Notizen: Zusammenfassung 60 aufeinanderfolgende fetale CTG-pH-Registrierungen (Cardiotokographie mit kontinuierlicher pH-Wert-Registrierung) wurden analysiert, um die Ursachen für nicht auswertbare Aufzeichnungen herauszufinden. Von den 60 Registrierungen zeigten 21 gute Qualität, 16 waren teilweise auswertbar und 23 nicht brauchbar. Die Registrierdauer pro Patientin betrug zwischen 5 und 530 min, durchschnittlich 154 min. Die Qualität der kontinuierlichen pH-Wert-Registrierung war unabhängig von der Dauer der pH-Wert-Uberwachung, dem mütterlichen Alter oder der Parität und auch von dem Gewicht des Kindes. Wurde die Elektrode zu früh appliziert (Muttermundweite unter 5 cm), so war das Risiko einer erfolglosen Registrierung großer. Die Drift der Elektrode lag unter 0,06 pH-Einheiten bei 90% der Fälle. Die Anzahl nicht erfolgreicher Aufzeichnungen liegt immer noch zu hoch und auch die Schwierigkeiten bei der Sterilisation, Eichung und Applikation der Elektrode sind noch zu ausgeprägt. Aus diesen Gründen sollte die pH-Elektrode z. Z. noch nur für wissenschaftliche Untersuchungen eingesetzt werden.

    Beschreibung: Cold and solar urticaria are subtypes of inducible urticaria. Both are much rarer than chronic spontaneous urticaria. Few patients suffer from several types of inducible urticaria 1 . Solar urticaria is a photodermatosis, restricted to UV-light exposed areas. Solar and cold urticaria manifests as pruritus with wheals with or without angioedema within minutes after topical radiation (ultraviolet or visible light) or cold exposure. The skin changes last a few minutes to several hours and spontaneously resolve completely 2 .Cold urticaria is responsible for about 3% of chonic urticaria cases. It may lead to emergency situations when breathing cold air induces angioedema of the upper airways 3 . This article is protected by copyright. All rights reserved.
