RESUMEN
Perimortem caesarean section can be decisive for the outcome of a cardiac arrest in pregnancy for both mother and fetus. We describe a case story of the management of cardiac arrest in early labour where perimortem caesarean section proved to be life-saving for both mother and child. The child was delivered alive seven minutes after recorded cardiac arrest, and the mother had return of spontaneous circulation one minute after delivery. The mother recovered well with no serious sequelae to the resuscitation. We discuss the importance of timely decision and execution of perimortem caesarean.

Human leukocyte antigen (HLA)-G is a class Ib molecule with restricted tissue distribution expressed on trophoblast cells and has been proposed to have immunomodulatory functions during pregnancy. Soluble HLA-G1 (sHLA-G1) can be generated by the shedding of membrane-bound HLA-G molecules; however, three soluble isoforms also exist (HLA-G5 to -G6). During pregnancy, it is unknown whether there is a correlation between sHLA-G levels in maternal and fetal blood. In 246 pregnancies, we have measured the levels of sHLA-G1/-G5 in maternal blood plasma samples from gestational week 20 (GW20) and at term, as well as in umbilical cord blood samples. Soluble HLA-G levels declined by 38.4% in maternal blood from GW20 to term, and sHLA-G levels were significantly lower in maternal blood at term than in GW20 (P<0.001). At term, the sHLA-G levels were significantly higher in maternal blood than in umbilical blood (P<0.001). HLA-G levels in maternal blood in GW20 and at term, and in maternal blood at term and umbilical cord blood, were correlated (P<0.001 and P<0.01, respectively). This is the first large study simultaneously measuring sHLA-G in both maternal and umbilical cord blood. The finding that sHLA-G levels are significantly lower in fetal compared with maternal blood at term documents for the first time that sHLA-G is not freely transferred over the placental barrier. Soluble HLA-G levels in maternal and fetal blood were found to be correlated, which may be due to shared genetic factors of importance for production of sHLA-G in the mother and child, or it may support the theory that sHLA-G in the pregnant woman and the fetus is partly derived from a "shared organ", the placenta.

Human leukocyte antigen (HLA)-G is a class Ib molecule with restricted tissue distribution expressed on the extra-villous trophoblast and seems to have immunomodulatory functions during pregnancy. Studies have linked HLA-G polymorphisms to pregnancy complications such as preeclampsia and recurrent miscarriage. Levels of soluble HLA-G (sHLA-G) in blood plasma from non-pregnant donors seem to be associated with these polymorphisms. In the current study, we have genotyped 246 mothers and their offspring for HLA-G polymorphisms in the 3'-untranslated region (3'UTR) and measured sHLA-G in maternal blood plasma samples from gestational week 20 and at term, as well as in fetal umbilical cord blood samples. This is the first large study simultaneously performing HLA-G genotyping of mother and offspring and measuring sHLA-G in both maternal and umbilical cord blood. The results showed that increasing numbers of 14bp ins (rs66554220) alleles in the mother-child genotype combinations were associated with higher maternal sHLA-G levels at term when restricting the analysis to 14bp ins/del heterozygous mothers (p=0.015). Furthermore, increasing numbers of 14InsG haplotypes (14bp ins/del and +3142C/G (rs1063320) polymorphism) in mother-child genotype combinations were associated with higher levels of sHLA-G at term in heterozygous 14DelC/14InsG mothers (p=0.005). In conclusion, the results indicate that there is an association between combined feto-maternal HLA-G genotypes and sHLA-G levels in maternal blood plasma.

Providing epidural analgesia in patients with scoliosis may be challenging. We describe ultrasound-guided insertion of an epidural catheter for labour analgesia and a following caesarean section in a patient with a thoracolumbar scoliosis. A well-functioning epidural catheter was easily inserted on the first attempt without any need for redirections of the epidural needle. Use of ultrasound imaging to guide epidural needle insertion site and trajectory can be a valuable tool in managing patients with scoliosis.

PROBLEM: Specific pro-inflammatory cytokine profiles in plasma may characterize women with recurrent miscarriage (RM) but the dynamics of the cytokine profiles with progressing pregnancy is largely unknown. METHOD OF STUDY: Plasma was repeatedly sampled in the first trimester from 47 RM patients. The concentrations of five cytokines including tumour necrosis factor alpha (TNF-α) were measured. TNF-α levels were correlated to carriage of five TNFA promoter polymorphisms. RESULTS: TNF-α levels increased (P = 0.014) with progressing pregnancy, with higher levels in secondary than primary RM (P = 0.042) but with no significant impact on outcome. Carriage of TNFA -863C and TNFA -1031T was associated with higher TNF-α levels, and the former was found more often in secondary than primary RM (P < 0.02). CONCLUSION: Plasma TNF-α levels increase during early pregnancy in RM women regardless of outcome, but are higher in secondary than primary RM, which may be partly genetically determined.
