Abstract Objectives To describe the association between the rapid normalization of pCO2 after intubation in a patient with severe bronchopulmonary dysplasia managed with permissive hypercapnia, with the risk of developing hypocalcemia and seizures, and to make health care providers aware of this risk in similar cases. Case presentation An extreme premature infant, born at 25 weeks of gestational age (GA), developed a severe bronchopulmonary dysplasia (BPD) and, after several extubation failures could be managed with non-invasive ventilation and permissive hypercapnia, with capillary pCO2 of up to 80 mmHg and pH >7.20. At 46 postmenstrual age (PMA) he was intubated because of severe hypercapnia and compensating metabolic alkalosis. About 20 h after intubation, after normalization of pH and pCO2, he developed hypocalcemia and seizures, that remitted after iCa normalization. A comparison between arterial and capillary blood gases showed a significantly greater correlation between pH and iCa in arterial than in capillary samples. Conclusions Our findings emphasize the importance of avoiding the abrupt reduction of pCO2 and the close monitoring of acute metabolic changes after its correction in chronic patients with permissive hypercapnia, as well as the potential superiority of arterial samples over capillaries to improve the precision of this control.

Abstract Objectives Lymphatic malformations are benign vascular anomalies comprised of lymphatic elements and most commonly occur in the neck. They may be diagnosed prenatally on ultrasound, and, in addition to confirming the diagnosis, fetal MRI can delineate the presence and extent of airway involvement. A variety of therapies are available for the treatment of lymphatic malformations including medical management, sclerotherapy, and surgery. Case presentation We report a case of a 28 year-old pregnant female diagnosed with a fetal neck mass by ultrasound at 21 weeks gestation. A fetal MRI was performed which demonstrated a multiseptated cystic neck mass most suggestive of a lymphatic malformation. The mass was noted to be intimately associated with the fetal airway. Follow up ultrasounds showed continued growth of the lesion throughout pregnancy. The baby was born by EXIT procedure and the lymphatic malformation was ultimately treated by a combination of medical treatment, sclerotherapy, and surgery. Conclusions Cervical lymphatic malformations have a classic imaging appearance and can enlarge throughout gestation as well as after delivery. The treatment plan typically involves a multidisciplinary approach.

Abstract Objectives This is the report of the first pregnant woman having COVID-19 in Vietnam. The patient was at 21 weeks of gestation and a high level of serum D-dimer and fibrinogen was observed from admission day to day 5. Case presentation The patient had lived in Russia before returning to Vietnam where she was diagnosed with COVID-19. Clinical characteristics of this patient were described and there was no major derangement of laboratory parameters. She was asymptomatic when being diagnosed and then developed mild symptoms of COVID-19 after three days of admission. The patient was treated with lopinavir/ritonavir, ampicillin/sulbactam, and Lovenox and continued being hospitalized until April 25th, 2020. Conclusions We presented the clinical picture of the first COVID-19 pregnant case in Vietnam. This case report highlighted the increased risk of developing coagulopathy even in mild and asymptomatic patients.

Abstract Objectives Thanks to the advances of modern medicine it has become possible to reach a fertile age even in the case of serious illnesses, enabling those patients to realize their desire to have children. This is also the case with the extremely heterogeneous, often autosomal dominantly inherited osteogenesis imperfecta. Due to a disruption in collagen synthesis those patients are faced with multiple fractures, spinal deformities and a decrease in pulmonary capacity throughout the course of their lives, depending on the subtype and severity of the disease. Obstetricians as well as anesthetists face major interdisciplinary challenges in the case of a pregnancy in those patients because of pregnancy-associated risks like uterine rupture, preterm birth and postpartum hemorrhage as well as risks associated with the nature of osteogenesis imperfecta itself, like bone fractures, spinal deformities and decreased mobility in the course of the progressing pregnancy. Mode of delivery should be planned individually in order to minimize maternal morbidity and mortality. In cases in which the fetus is as well affected by the disease, this aspect must be taken into consideration when it comes to supervision of pregnancy and planning of the birth mode. Case presentation We report the case of a woman with osteogenesis imperfecta type III who spontaneously conceived a pregnancy with a fetus who was also affected by the genetic disease. This constellation has up to now been reported by only few sources and requires supervision by an experienced perinatal center. Conclusions Osteogenesis imperfecta is not an exclusion diagnosis for family planning and a successful delivery. Nevertheless, depending on the form of the disease, mother and child can be severely affected by the disturbed collagen synthesis. Each patient has to be individually advised and cared for with the specific risks due to the type of Osteogenesis imperfecta. In the case of type III, due to extreme scoliosis, pelvic deformity and small growth, only a primary cesarean section can be performed.

Abstract Objectives Emanuel syndrome is a rare inherited syndrome, a correct in utero diagnosis allows effective management for ongoing and future pregnancies. Case presentation Here, we report a case of a complete non-mosaic trisomy 22, with several prenatal sonographic findings, that was diagnosed in utero at 15 weeks’ gestation and then it was confirmed with chromosomal analysis and postmortem examination. Conclusions Every anatomical difference should always be further investigated in order to achieve the correct diagnosis.

Abstract BackgroundCongenital high airway obstruction syndrome (CHAOS) is a rare disease and recently has been noticed to show typical prenatal images, such as hyperinflated lungs and flattened or inverted diaphragms. However, in some cases correct diagnosis may be difficult and in such cases the mortality rate increases.Case presentationWe report four cases of CHAOS complicated with a high airway fistula to the alimentary tract and foregut malformation. The patients did not show the typical features of CHAOS in the fetus. This may be attributed to the high airway fistula acting as a decompression route for the accumulated lung fluids to the alimentary tract.ConclusionThe combination of CHAOS, foregut malformation and a high airway fistula is very rare and classified into four distinct types: (1) CHAOS with a high airway fistula but not with a foregut malformation; (2) CHAOS with esophageal atresia and tracheoesophageal fistula; (3) CHAOS with a high airway fistula and duodenal atresia; and (4) CHAOS with esophageal atresia, tracheoesophageal fistula and duodenal atresia. It may be useful for treating physicians to be aware of these four distinct types and the typical characteristics of each type.

Abstract Ojectives Transient neonatal Myasthenia gravis is a postsynaptic neuromuscular junction disorder seen in 10–21% of infants born to mothers with myasthenia gravis. Alemtuzumab is an anti-CD52 monoclonal antibody used in the treatment of multiple sclerosis. The possibility of developing Myasthenia gravis in a pregnant mother treated with Alemtuzumab is rare. Case presentation We report a case of transient neonatal myasthenia gravis following treatment with Alemtuzumab for multiple sclerosis in the mother. Conclusions Therapy with Alemtuzumab increases the risk of secondary autoimmune diseases including Myasthenia gravis.

Abstract ObjectivesThe spinal dysraphism and situs inversus are a rare association. Since 1909, reports on the coincidence of malformations of the spine and gastrointestinal tract have been published. So far there is no plausible explanation for the association.Case presentationWe report a term female infant with spinal dysraphism with club feet associated with dextrocardia and situs inversus totalis. Whole genome SNP microarray analysis was normal. However, there are extended contiguous regions of allele homozygosity [>8 Mb[megabase]) observed in chromosome 6 and 14.ConclusionsWe report a rare association of spinal dysraphism and situs inversus totalis in a neonate. We review the literature. There have recently been theorized by some to in fact represent nothing more than the presence of two or more polytopic field defects, with all the anomalies present sharing a common molecular basis.

Abstract Background Uterine sacculation with a resulting uterine rupture is a rare complication in pregnant patients. Fibroids or a previous cesarean section increase the risk of severe complications such as a uterine rupture due to increased pressure and the elongation of the affected uterine segment. Prenatal clinical diagnosis and medical imaging of a uterine sacculation and rupture of the uterus remain challenging, even with the most modern imaging techniques. An early diagnosis is essential to reduce severe complications. Case presentation Here, we report the case of a 38-year-old female patient II G I P in the 19th week of pregnancy with a ruptured uterine sacculation. Conclusion This case report is intended to raise awareness for the importance of the knowledge and supervision of a retroverted uterus in early pregnancy, especially after a cesarean section.

Abstract Fetal head entrapment by a uterine scar or adhesion is a rare obstetric complication. We present a case of a uterine constriction diagnosed in pregnancy that resulted in confinement of the fetal head to the lower uterine segment. The developing fetus ultimately suffered growth restriction of the head and was delivered after the mother experienced preterm premature rupture of membranes (PROM). Severe adhesions of the lower uterine segment were confirmed during the patient’s classical cesarean section.
