RESUMO
OBJECTIVES: Maternal gestational diabetes mellitus (GDM) is known to influence fetal physiology. Phase-rectified signal averaging (PRSA) is an innovative signal-processing technique that can be used to investigate fetal heart signals. The PRSA-calculated variables average acceleration capacity (AAC) and average deceleration capacity (ADC) are established indices of autonomic nervous system (ANS) function. The aim of this study was to evaluate the influence of GDM on the fetal cardiovascular and ANS function in human pregnancy using PRSA. METHODS: This was a prospective clinical case-control study of 58 mothers with diagnosed GDM and 58 gestational-age matched healthy controls in the third trimester of pregnancy. Fetal cardiotocography (CTG) recordings were performed in all cases at entry to the study, and a follow-up recording was performed in 19 GDM cases close to delivery. The AAC and ADC indices were calculated by the PRSA method and fetal heart rate short-term variation (STV) by CTG software according to Dawes-Redman criteria. RESULTS: Mean gestational age of both groups at study entry was 35.7 weeks. There was a significant difference in mean AAC (1.97 ± 0.33 bpm vs 2.42 ± 0.57 bpm; P < 0.001) and ADC (1.94 ± 0.32 bpm vs 2.28 ± 0.46 bpm; P < 0.001) between controls and fetuses of diabetic mothers. This difference could not be demonstrated using standard computerized fetal CTG analysis of STV (controls, 10.8 ± 3.0 ms vs GDM group, 11.3 ± 2.5 ms; P = 0.32). Longitudinal fetal heart rate measurements in a subgroup of women with diabetes were not significantly different from those at study entry. CONCLUSIONS: Our findings show increased ANS activity in fetuses of diabetic mothers in late gestation. Analysis of human fetal cardiovascular and ANS function by PRSA may offer improved surveillance over conventional techniques linking GDM pregnancy to future cardiovascular dysfunction in the offspring.

Fetal magnetocardiography (fMCG) is used as a non-invasive method for registering the electrophysiological fetal heart activity. Superconducting quantum interference device-based magnetometers are currently used to make fMCG recordings. In contrast to fetal ECG, this method is independent of signal loss due to isolating factors such as, especially, the vernix caesaroa between the 27th and 34th weeks of gestation. We report about a term newborn with a third degree AV block, examined by this method.

INTRODUCTION: Anaplastic astrocytomas presenting as gliomatosis cerebri in neonates are extremely rare. Tumours in newborns are mostly of neuroectodermal origin. CASE REPORT: We report about a female newborn at term [birth weight 3 600 g (P 90), head circumference 35 cm (P 95) APGAR 9/10/10] with an intracerebral partially clotted bleeding in the left parieto-occipital region. The bleeding was expansive leading to axial and lateral cerebral herniation. The intracerebral bleeding in the left occipital region was surgically removed. Macroscopically no solid tumour was seen, but small fragments of an anaplastic astrocytic tumour (WHO grade III) were diagnosed histologically. After surgery, no remaining tumour was visible in the MRI. 6 weeks later, a recurrent tumour (4×4 cm) was found in the area of the initial bleeding. Further treatment was initially refused by the parents. The child was readmitted to our hospital at the age of 11 months in good clinical condition and presented with left-sided hemiparesis, right-sided hemianopsia and intermittent strabismus convergens alternans. Because of the good clinical condition further therapeutic treatment was initiated. Due to the final extension of the tumour into the temporal, parietal and occipital lobes, a gliomatosis cerebri WHO III was diagnosed. An extended partial hemispherectomy was done. After neurosurgery, no further neurological failures occurred. In the follow-up examination, MRI showed no relapse of the tumour. Chemotherapy according to the HIT SKK protocol was initiated. A relapse did not occur over a follow-up of 2 years. CONCLUSION: This is a rare case report of a congenital gliomatosis cerebri WHO grade III, treated with partial hemispherectomy, leading to a good clinical and neurological long-term outcome.

Prenatal diagnosis of a huge coronary artery fistula between the left coronary artery and the right ventricle was made by Doppler echocardiography at 22 weeks of gestation. Progression of the dilated fistula was monitored throughout pregnancy. The size of the fistula increased enormously up to 11 mm. Death occurred at birth. Monitoring of these fetuses is essential as severe complications can occur during pregnancy or at birth.
RESUMO
BACKGROUND: Pregnancy in women with congenital cardiac disease is more frequent due to an increased lifespan and improved health situations. However, the long-term outcomes in these women are not known. METHODS: We analysed 267 consecutive pregnant women with congenital heart defects who were seen at the German Heart Centre Berlin. This retrospective study included analysis of long-term follow-up data after pregnancy and standard maternal cardiac, obstetric and neonatal outcomes. The long-term data (n = 103) were acquired with a self-assessment questionnaire from each patient. The main primary outcomes of the study included functional class, health, work capability and physical activity. RESULTS: The median age of the patients at delivery was 27 years (range 17-43 years). The median follow-up of all patients was 11 years (range 1-49 years). Twenty-four percent exhibited complex cardiac defects. Primary long-term outcomes included good health in 61 % of the patients. Approximately 68 % worked, and 76 % engaged in physical activity. Thirty-three percent of the women who answered the questionnaire demonstrated a decrease in functional class during pregnancy, but more than two-thirds of these patients subsequently improved. Secondary short-term outcomes included a 4 % miscarriage rate and a 4 % induced abortion rate. The maternal cardiac data revealed that 30 % of the patients lost at least one functional class during pregnancy. Onset arrhythmias were observed in 12 % of the patients. The most prevalent neonatal complication was premature birth, which was present in 12 % of the neonates. CONCLUSION: Two-thirds of the patients tolerated pregnancy without cardiovascular complications. Most patients displayed good long-term health, work capability and physical activity outcomes. Further prospective controlled studies are necessary to confirm these results and safely advise pregnant women.
