[Requirements and current state of birth documentation in Germany]. / Moderne Anforderungen und derzeitiger Standard in der Geburtsdokumentation in Deutschland.

INTRODUCTION: The partogram is a central record in everyday practice for midwifes and obstetricians. For legal enquiries it is one of the most important documents, however, so far there is no standardised partogram in use in Germany. This study explores the current requirements and develops a standardised partogram. MATERIAL AND METHODS: In Germany 95 hospitals with a focus on tertiary referral centres were randomly selected to be questioned. Obstetricians and midwifes were asked to answer a questionnaire, which was based on a current literature search and expert interviews. RESULTS: 49 obstetricians (51.6%) and 24 midwives (25.3%) returned the questionnaires. 80% of those regularly cooperate with the other specialty with a partogram. 75% are using a standardised partogram, 8% an empty page and 6% computerised obstetric records. Most responders are using parameters which are defined in the current guidelines of the German Society of Obstetrics and Gynaecology. Variations were especially pronounced in the scoring system of the cardiotocogram and on legal issues. Room for improvement of the current documentation was documented in half of the cases. DISCUSSION: There is a need for optimising the current birth documentation. With the results of the questionnaire a standardised model for a partogram was developed.

Prenatal Foetal Non-invasive ECG instead of Doppler CTG - A Better Alternative?

Introduction: This study aimed to evaluate foetal signal quality obtained using an antenatal foetal ECG system (Monica 24™) and compare it with Doppler ultrasound CTG monitoring (Corometrics® 250 series). Material and Methods: Seventy pregnant women (gestational age: between 20 + 0 weeks and 40 + 0 weeks) were examined using the Monica AN24™ system and also underwent Doppler CTG. The signal quality of both methods was compared and correlated with gestational age and pre-pregnancy body mass index (BMI). Results: Overall, ECG had a signal quality of 77.4 % and CTG had a signal quality of 73.1 % (p > 0.05). In gestational weeks (GW) 20-26, the signal quality of ECG was significantly better compared to that obtained with CTG (75.5 vs. 45.3 %; p = 0.003), while in GW 27-36, the signal quality was better with CTG (72.3 vs. 83.0 %, p = 0.001). No difference in signal quality was found between the two methods after the 37th GW (87.7 vs. 86.1 %; p > 0.05). CTG showed a statistically significant correlation with BMI (rho 0.25, p < 0.05) while ECG showed no such correlation. Conclusion: The use of non-invasive ECG is particularly indicated in the early weeks of pregnancy, while CTG offers superior results during the vernix period. There was no difference in signal quality after the vernix period. The signal quality with ECG was found to be independent of BMI, while the signal quality of CTG deteriorated with increasing BMI.

Change of Spectral Analysis of Fetal Heart Rate During Clinical Hypnosis: a Prospective Randomised Trial from the 20th Week of Gestation Till Term.

Objective: To investigate the functional adaptive process of the fetal autonomic nervous system during hypnosis from the 20th week of gestation till term. Are there changes in the power spectrum analysis of fetal heart rate when the mother is having a clinical hypnosis or control period? Study Design: Fourty-nine FHR recordings were analysed. Included recordings were from singletons and abdominal fetal ECG-monitored pregnancies. All women were randomised to receive clinical hypnosis followed by a period with no intervention or vice versa. Statistical analyses were performed with the Wilcoxon signed ranks and Spearman rho correlation tests. Results: There was a significant difference found between fetal heart rate at baseline (144.3 ± 6.0) and hypnosis (142.1 ± 6.4). A difference was also detected between the standard deviation of the heart rate between baseline (6.7 ± 1.9) and hypnosis (6.8 ± 3.5). LFnu was smaller during baseline (80.2 ± 5.3) than during hypnosis (82.1 ± 5.7), whereas HFnu was significantly larger (19.8 ± 5.3 vs. 17.9 ± 5.7). There was no correlation between the gestation age and the change in LFnu, HFnu or ratio LF/HF due to the hypnosis intervention. Conclusion: The functional adaptive process of the fetal autonomic system during hypnosis is reflected by a sympathovagal shift towards increased sympathetic modulation.

Uterine activity monitoring during labour--a multi-centre, blinded two-way trial of external tocodynamometry against electrohysterography.

PURPOSE: The aim of this study was to determine the quality of intrapartum uterine activity (UA) monitoring in daily practice during the first and second stages of labour. The total duration of inadequate UA monitoring is quantified in relation to the technique applied, namely, external tocodynamometry (TOCO) or electrohysterography (EHG). MATERIAL AND METHODS: 144 UA recordings, collected from 1st September 2008 until 15th October 2009 from deliveries at the Marien-Hospital Witten, Germany, were analysed by obstetricians based at different centres. The included recordings were from singleton and simultaneously with external TOCO and EHG monitored pregnancies. External TOCO and EHG UA recordings were blinded. RESULTS: The percentages of "adequate" UA recordings in the first and second stages of labour were much higher for the external EHG than the external TOCO mode (p<0.001). All doctors evaluated the UA assessment as "easier" (p <0.001) using the EHG compared with TOCO. CONCLUSION: Intrapartum UA monitoring in -daily practice via the EHG mode provides a more recognisable UA trace than the TOCO.

[Case reports of operative management of very large, benign phylloid tumors--is a safety margin necessary?]. / Fallberichte über operatives Management bei sehr grossen, benignen Phylloidtumoren--Ist ein Sicherheitssaum notwendig?

The phylloid tumor (PT, formerly called cystosarcoma phylloides) is a rare neoplasia of the female breast. Usually the PT is treated with breast-conserving surgery. In spite of progress in early diagnosis, PTs recur frequently--independently of tumor's degree of malignancy. Especially in cases of malignant PT, complete resection with tumor-free margins is seen as the only predictive marker for tumor recurrence or metastases. Benign PT is also often resected with wide tumor-free margins. Because of the tumor's occasionally enormous dimensions, this therapy concept makes breast-conserving surgery almost impossible. A simple enucleation of benign PT is an option to facilitate the preservation of breast tissue and a cosmetically satisfactory breast reconstruction. In the case of particularly large benign PT, enucleation even without wide margins prevents tumor recurrence.

Sensitivity and specificity of intrapartum computerised FIGO criteria for cardiotocography and fetal scalp pH during labour: multicentre, observational study.

OBJECTIVE: To identify sensitivity and specificity of computerised cardiotocography (CTG) analysis for fetal acidosis during delivery. DESIGN: Retrospective observational study. SETTING: Tertiary referral labour ward, Technical University München (TUM) and University Witten/Herdecke (UWH). POPULATION: All deliveries, which had at least one fetal scalp pH measurement and electronically saved CTG traces, between 2000 and 2002 (TUM) and between 2004 and 2005 (UWH). METHOD: Correlation analysis of fetal scalp pH values and computerised International Federation of Obstetrics and Gynecology (FIGO) classification using 'CTG Online' program of digitally saved CTG traces. MAIN OUTCOME MEASURES: Fetal scalp pH values, FIGO parameter (baseline, variability, acceleration and deceleration) using computerised analysis. RESULTS: Both collectives showed a high sensitivity (95.0%) for computerised FIGO classification 'suspect' and 'pathological', together with a low specificity (21.8%) for fetal acidosis. The most sensitive single FIGO parameter was deceleration. Very low sensitivity (<50%) was shown for the parameters variability and acceleration. CONCLUSIONS: Computerised CTG analysis is highly sensitive for fetal acidosis and can be used as an objective adjunctive criterion during delivery. Further CTG data are needed to adjust and optimise each FIGO parameter and increase sensitivity and specificity.

[The significance of electronic CTG for intrauterine volvulus in the 32nd week of gestation]. / Die bedeutung der elektronischen CTG-analyse bei einem fetalen Volvulus in der 32. SSW.

Intrauterine intestinal volvulus is a difficult diagnosis to make, but has life-threatening implications for the fetus. We present a case of vulvulus without malrotation in a single fetus revealed in the 32nd gestation week in a 44-year-old woman. The presenting complaint of this patient was reduced fetal movements. Ultrasound examination showed a normal result except for a dilated stomach. Doppler ultrasound results were within the normal range. Computed cardiotocography (CTG) showed pathological results for acceleration and suspect values for variability. Short-term variability (STV) was at 2.80 ms. Due to the pathological computed CTG results a Caesarian section was carried out. The newborn received prompt postnatal surgical treatment and continues to be in good overall condition.

[Fetal heart rate variation in magnetocardiography and cardiotocography--a direct comparison of the two methods]. / Die fetale Herzfrequenzvariation in der Magnetokardiografie und der Kardiotokografie--direkter Vergleich beider Verfahren.

BACKGROUND: Heart rate variability (HRV) is becoming increasingly important in the analysis of prepartal cardiotocography (CTG). Dawes and Redmann have developed a computer algorithm which can calculate short-term variability on the basis of CTG data. In dealing with artefacts, CTG monitors average heart rate values over several beats which makes the use of standard measures of HRV such as the root mean square of successive differences (RMSSD) inappropriate. Fetal magnetocardiography (FMCG) enables the registration of signals similar to the electrocardiogram and this permits the precise determination of heart beat duration and, in consequence, of measures of fetal HRV. METHODS: In this study we applied both methods--CTG and FMCG--sequentially and simultaneously in healthy pregnancies. Fetal short-term HRV was estimated on the basis of RMSSD values for both methods. RESULTS: The RMSSD values of the FMCG data were generally higher and showed a wider dynamic range than those of the CTG. The direct comparison of the simultaneously acquired data demonstrated that the data processing of the CTG signal leads to a suppression of essential aspects of short-term HRV. CONCLUSION: FMCG permits a substantially more differentiated examination of fetal HRV and offers new possibilities in the analysis of fetal cardiac activity.

[Short time variation of foetal heart rate: therapeutic management and effect on heart rate variation in the context of chronic hypotension in the 27th week of gestation]. / Die Kurzzeitvariabilität der fetalen Herzfrequenz - Therapeutisches Management und Auswirkungen auf die Herzfrequenzvariabilität bei einer drohenden Entgleisung einer chronischen Hypertonie in der 27. SSW.

The non-stress test is the most commonly used method in prepartal surveillance. Due to the high intra- and interobserver variability involved in subjective evaluation, the computer-assisted analysis is gaining in importance. Some studies have shown that low foetal STV may be associated with higher rates of acidosis and intrauterine mortality. Other factors influencing STV are largely not known. Low STV has been found as an effect of cortisone. In this case report, we illustrate the relevance of haemodilation therapy in the context of essential hypertension in the 27 (th) week of gestation and its effect on SVT. The treatment led to a prolongation of pregnancy to the 32 (nd) week. At the start of treatment STV increased to 4.5 ms and dropped back below this value concurrently with centralisation as documented by Doppler sonography. STV correlated clearly with the foetal condition. However, STV is dependent on numerous factors which should be investigated in further studies in order to determine appropriate reference values.

Influence of gestational age, heart rate, gender and time of day on fetal heart rate variability.

From adult data, it is known that numerous factors, such as age, state of the autonomic nervous system, diurnal rhythms or mean R-R interval mRR, influence heart rate variability (HRV). The aim of this study was the examination of the influence of gestational age, mRR, gender and time of day on fetal HRV. The analysis was based on 66 fetal magnetocardiograms (FMCGs) of 22 healthy fetuses between the 16th and 42nd week. FMCGs were recorded for 5 min using a multichannel biomagnetometer. On the basis of the time series of fetal R-R intervals, mRR as well as the standard deviation sdRR, root mean square of successive differences rmssdRR and approximate entropy ApEn were calculated. The influence of gestational age, mRR and gender on sdRR, rmssdRR and ApEn was determined by regression analysis. The relationship between time of day and HRV was evaluated by visual inspection of scatterplots. The logarithmised HRV measures increased significantly with the logarithm of gestational age (regression coefficients: sdRR = 1.28, rmssdRR = 1.12, ApEn = 1.30) and mRR (regression coefficients: sdRR = 0.008, rmssdRR = 0.011, ApEn = 0.012) There was no significant influence of gender. With respect to time of day (between 0800 h and 1800 h), no dependency of the HRV measures was apparent. In summary, when fetal HRV is assessed, it is essential to take gestational age and mRR into account. In contrast, time of day, with respect to daytime, and gender need not be considered. In future studies, the influence of fetal activity state on HRV should be examined.

[Magnetocardiography--a possible supplementary method for early detection of fetal distress in high-risk pregnancies]. / Die Magnetokardiographie -- eine mögliche ergänzende Methode zur Früherkennung einer fetalen Gefährdung in Risikoschwangerschaften.

Ever since the first report on fetal magnetocardiography by Kariniemi in 1974 numerous studies have examined cardiac activity in healthy fetuses using this technique. Recently there has been an increase in reports on the identification of fetal pathological states, in particular in the diagnosis of fetal arrhythmias, using magnetocardiography. Other possible applications of this non-invasive method include the assessment of intrauterine growth retardation and fetal stress. In a patient with gestational hypertension and asymmetric growth retardation without pathological ultrasound findings, fetal magnetocardiography showed a reduced beat-to-beat heart rate variability indicating signs of fetal stress. On the day following the magnetocardiographic recording, fetal Doppler ultrasonography findings indicated an incipient brain sparing effect. The fetal growth retardation was reflected in the duration of the fetal cardiac time intervals. We conclude that fetal magnetocardiography non-invasively enables the timely identification of pathological fetal conditions.

Realtime visualization of tumor cell/endothelial cell interactions during transmigration across the endothelial barrier.

PURPOSE: In cancer the blood-borne spread of tumor cells leads to the formation of secondary tumors at distant loci whereby the extravasation of tumor cells is a prerequisite step during hematogenous metastasis. Here, we describe a novel in vitro realtime model which shows the complete sequence of the extravasation process. METHODS: We developed an in vitro system allowing us to monitor the sequence of extravasation events of tumor cell clusters across a monolayer of human umbilical cord endothelial cells (HUVEC). Fluorescence markers and laser scanning confocal microscopy were used to visualize the interactions between tumor cells and endothelium. RESULTS: Our model indicates that the extravasation of tumor cell clusters derived from the invasive human bladder carcinoma cell line T24 occurs in a relatively short time-frame up to 4 h after adhesion to the endothelium. We demonstrate that the vascular endothelium is irreversibly damaged at the site of tumor cell extravasation. CONCLUSION: Realtime laser scanning confocal microscopy leads to a better understanding of the complex and dynamic cell-to-cell and cell-to-matrix interactions during the extravasation process.

[Rupture of the uterine artery after spontaneous delivery with unusual course in childbed]. / Ruptur der Arteria uterina nach Spontangeburt mit ungewöhnlichem Verlauf im Wochenbett.

Haemorrhage from ruptured uterine vessels is a rare but life-threatening complication during pregnancy. The high rate of mortality associated with this condition is correlated to the rapidity of haematoma formation. The dynamics of this event become particularly evident at the time of birth when the uterus requires one-fifth of the cardiac output. This high rate of flow emphasizes the possible fatal consequences of delayed therapeutical intervention. Information available on the aetiology and pathogenesis of such events is poor, especially if an involvement of cervical vessels or extraperitoneal (incomplete) rupture of the uterus can be excluded. Diagnosis and therapy are based on the classical clinical symptoms of acute abdominal pain-and-shock symptomatology. We report on a 31-year old patient after spontaneous delivery and initially uneventful puerperium. She had to be laparotomised on the third day post partum because of pain and haemoglobin deficiency. We found a large retroperitoneal (supralevatorial) haematoma caused by ruptured lateral branches of the left arteria uterina. The uterus was preserved after haematoma removal and revision and suture of the bleeding vessels. The case reported on shows that peripartal rupture of arterial uterine vessels may turn out to be clinically relevant only after a relatively long time (> 72 hours). Only four comparable cases have been reported in the literature, the course being different from that in all the other cases. In all the documented cases arterial uterine haemorrhages resulted in short-term acute aggravation of the symptomatology with severe abdominal pain, haemodynamic collapse and simultaneous haemoglobin deficit. The case under report in the present paper was at first clinically occult and eventually developed a pathology that had not been described before. Its specific significance lies in illustrating the need for re-evaluating such initially hidden cases while paying special attention to ruptured uterine vessels.

Does texture analysis improve breast ultrasound precision?

OBJECTIVE: To evaluate the possibility of distinguishing between benign and malignant breast tumors using a computer-aided evaluation of echogenicity and echostructure of ultrasound findings at certain focal points. STUDY DESIGN: The ultrasound images from 89 cases of breast tumor were documented under standardized conditions using a linear array machine and 7.5 MHz transducer. In each sonographic image, the maximum area of the 'region of interest' of the tumor was marked and then subjected to consecutive statistical analysis and correlation with the histological findings. For evaluation of tumor status eight parameters of first and second order texture statistics (gray level histogram, Fourier analysis, co-occurrence matrix) were applied. RESULTS: Benign tumors were clearly distinguished from carcinomas in the evaluation of the co-occurrence matrix and the Fourier analysis on the basis of Wilcoxon and Student t-test (P < 0.05) but not in the gray level histogram. Using logistic regression a sensitivity of 73.8% and a specificity of 54.2% were obtained. A statistically significant difference between benign tumors and moderately differentiated together with poorly differentiated carcinomas could be demonstrated. CONCLUSION: This study concludes that texture analysis appears to distinguish between benign and most malignant tumors. A computer texture analyzing system is able to improve the subjective assessment of ultrasound images of the breast but can not replace it. Where the limits of subjective assessment of a given tumor are reached, computerized texture analysis will provide additional information in the differentiation of benign from malignant findings.

Comparison of cytosolic p53 protein levels in the female genital tract and breast, and their tumors.

Under normal conditions, p53 protein is thought to maintain genomic stability. We measured this parameter in healthy tissues from female breast and genital tract using a quantitative, highly sensitive luminometric assay. An organ-specific pattern of p53 expression became evident: breast parenchyma (n = 40, median p53: 0.0346 ng/mg protein) and ovarian tissue (n = 12, 0.063 ng/mg) demonstrated markedly higher p53 levels than endometrium (n = 24, 0.0065 ng/mg), myometrium (n = 31, 0.005 ng/mg) or uterine cervix tissue (n = 25, 0. 002 ng/mg). Malignant tumors derived from these organs maintained the pattern of p53 expression with ovarian cancers (n = 14, median: 0.84 ng/mg) exceeding all other tissue types examined. Generally, p53 concentrations in malignant tumors, but also in uterine myomas were significantly higher than those in healthy controls. Breast cancer tissues, subgrouped according to prognostic parameters, demonstrated the highest p53 concentrations in samples with atypical histology, grading II-III, negative steroid receptors, and in cases of positive axillary lymph nodes. The frequency of elevated p53 concentrations in cancer cytosols, based on organ-specific normal concentrations, varied between 62% in breast cancers and 100% in cervical carcinomas. Uterine myomas showed 6% of elevated values. Grade II-III breast carcinomas overexpressed p53 more often than those with grading I (p < 0.05). In all carcinomas, the frequencies of overexpressed p53 protein markedly exceeded the frequencies of mutated p53 gene mutations reported in the literature. In conclusion, our data indicate that the extent of p53 expression and overexpression is organ dependent. When data of other studies on primary breast cancers are included, elevated levels of p53 protein in malignant tumors to some extent may indicate p53 gene mutations and worse prognosis if they exceed a higher threshold.

Fetal heart rate variability and complexity in the course of pregnancy.

Aim of this study was the examination of fetal heart rate variability and complexity measures during pregnancy using fetal magnetocardiography. We registered 80 fetal magnetocardiograms in 19 healthy fetuses between the 16th and 41st week of gestation. On the basis of beat to beat intervals, mean RR interval (mRR), its standard deviation (SD), root mean square of successive differences (RMSSD), as well as complexity variables such as dimension (ApD1), entropy (ApEn), Lyapunov exponent (ApML) and trajectory divergence rate (p) were calculated for each recording. Dependency of these variables on gestational age was evaluated with correlation analysis. All variables changed consistently over time. RMSSD showed the strongest dependency on gestational age, followed closely by ApEn, SD and p. ApD1 and mRR showed only weak dependency. We conclude that magnetocardiography is well suited to register fetal cardiac activity with sufficient accuracy to permit detailed analysis of various heart rate variables during the second and third trimester of pregnancy. The observed increases in heart rate variability and complexity of fetuses most likely reflect differing but overlapping aspects of fetal development. They may be linked to the maturation of the autonomic nervous system and could aid in the timely identification of pathological conditions.

[Erythropoietin and obstetric factors--evaluation with special reference to sex differences]. / Erythropoietin und geburtshilfliche Einflussgrössen--Evaluation unter besonderer Berücksichtigung von Geschlechtsunterschieden.

OBJECTIVE: We evaluated fetal Erythropoietin (EPO) in a clinical obstetrical environment, aiming to collect more information upon its role in diagnosis of fetal stress. As it is known that EPO cannot pass the placental barrier, we restricted to measure the concentration in the umbilical artery (UA) immediately after delivery. PATIENTS AND METHODS: EPO was correlated to relevant obstetrical parameters. We looked for each parameter that was tested for differences in fetal sex. For this purpose, the statistics were performed by means of the Behrens-Fisher-Test (meaning a special application of the Student-T-Test). This device is an algorithm developed to compare regressions. For significance, a confidence level of less 5% was accepted. For the rest, we only used descriptive devices. RESULTS: We found weak but positive correlation to gestational age for both sexes. No correlation was calculated for the duration of parturition or the birth weight. Highly significant differences were found for respiratory values of blood gases, taken from the UA when differentiated for fetal sex: males showed a strong and negative correlation for pO2 (r(m)= -0.45); the female EPO-level was not influenced by decreasing O2-level (r(w)= +0.06, p > 0.01). Similar results could be found for pCO2. (r(m)= +0.36; r(w)= -0.07; p < 0.01. Not significant, but comparable differences for the EPO-level in fetal blood were found for pH and base deficit. CONCLUSIONS: If we accept that the EPO-level in fetal blood rises with relevant oxygen deficiency, then females seems to be better protected against damage from distress. This observation is congruent with the clinical experience from the authors who have the subjective impression that female sex is advantageous in harmful deliveries.

[Oral contraceptive use and vaginal candida colonization]. / Einnahme oraler Kontrazeptiva und vaginale Kandidabesiedlung.

Fungal vaginal infections/colonisations can be divided into a symptomatic vaginal candidiasis and an asymptomatic vaginal Candida-carriage. The latter seems to be a predisposing factor for the development of a symptomatic vaginal candidiasis. The fungal organism isolated most frequently is Candida albicans, followed by Candida glabrata, which was previously also known as Torulopsis glabrata. To a lower extend, other Candida species such as Candida tropicalis and Candida krusei can be prevalent in the vulvovaginal region. Predisposing factors for vaginal candidiasis are gravidity, diabetes mellitus or a therapy with immunosuppressive agents. Also gestagenes showed to be a pre-disposing factor for vaginal candidiasis. Divergent results concerning the predisposition to vaginal candidiasis or colonisation due to oral contraception have so far been reported. Therefore we performed a study with two healthy collectives of female volunteers (n = 2 x 60) which were different concerning the taking of oral contraceptives. Overall, in 17% of the subjects (20/120) yeast could be cultured out of the vaginal secretions. There was no evidence for a higher rate of Candida-colonisation in subjects taking oral contraceptives. Further, there was no evidence for a relationship between the length of the taking of oral contraceptives and the rate of vaginal yeast-carriage. Also the type of oral contraceptive (combination or sequential contraceptive) had no influence on the frequency of Candida-carriage. Candida albicans was the most prevalent yeast (16/20), followed by Candida glabrata (4/20).

[Magnetocardiography for assessment of fetal heart actions]. / Magnetokardiographie zur Erfassung fetaler Herzaktionen.

Magnetocardiography provides a new, alternative method for fetal surveillance. This method allows the registration of changes in the magnetic field produced by the fetal cardiac system. In comparison to fetal ECG, the fetal magnetocardiogram (fMCG) is not affected by intermediate tissue, in particular by the insulating effect of the vernix caseosa. Furthermore fMCG's with a good signal noise ratio can be obtained in the second trimester. A multichannel biomagnetometer allows the non-invasive measurement of the magnetic signals produced by the fetus. Examples of dta and evaluation techniques are given. Signal processing software allows the identification of all fetal beats in a data set, permitting the calculation of an averaged beat and the evaluation of signal morphology and cardiac time intervals. Furthermore it is possible to produce a beat to beat time series with high temporal resolution, making the evaluation of heart rate variability with measures from the time, frequency, and phase domain accessible. Particularly the latter are of interest in investigating changes in temporal complexity of the fetal cardiac system. Magnetocardiography thus holds the promise of improved antenatal surveillance as of the second trimester.

[Excessive rise in plasma alkaline phosphatase in the last trimester of pregnancy]. / Exzessiver Anstieg der alkalischen Plasmaphosphatase während des letzten Trimenon der Schwangerschaft.

This article is concerned with the increase of alkaline phosphatase of a 32-year old primipara, five to six times higher than the upper basal values, during the last trimenon of pregnancy. The physiological increase of serum total alkaline phosphatase levels during pregnancy were two to three times higher than the basal values (4, 11). Hepatopathies, osteopathies, endocrinological disorders, infections as well as other medical causes were excluded by anamnesis due to close-meshed laboratory chemical and clinical controls relating to differential diagnosis. Thus, only pregnancy could be considered as a trigger mechanism. Differentiating the alkaline phosphatase by laboratory chemical means in the course of this pregnancy, an isolated increase of the alkaline phosphatase placenta isoenzyme (PLAP) was seen. Besides premature labour pains, which led to the admission of the patient to the maternity ward, around a calculated 32nd week of pregnancy, a discreet foetal growth retardation was recognised, which continued to increase constantly up to a minus discrepancy of three weeks. The delivery of a dystrophic girl took place at the beginning of the 37th week of pregnancy. Post partum alkaline phosphatase levels normalised to basal values. The correlation: the increase in PLAP and intra-uterine foetal growth-retardation was evident in the case presented and was also discussed in connection with previous observations by other authors of similar studies.
