Successful management of acquired hemophilia A onset during pregnancy: A case report.

Acquired hemophilia A (AHA) is a rare bleeding disorder caused by autoantibodies that inhibit coagulation factor VIII. Pregnancy could be associated with AHA in younger women. Because of its rarity, the optimal management for pregnancy-related AHA has not yet been established. Herein, we present the case of a 32-year-old woman with AHA diagnosed during pregnancy because of elevated activated partial prothrombin time, decreased factor VIII activity, and the presence of a factor VIII inhibitor. She was treated with immunosuppressive therapy consisting of corticosteroid and cyclosporine administration. Although complete remission could not be induced in the peripartum period, she gave birth safely by cesarean delivery in combination with prophylactic bypass hemostatic therapy. This work would provide helpful information to guide better recognition and treatment of pregnancy-related AHA cases.

Severe coronavirus disease pneumonia in a pregnant woman at 25 weeks' gestation: A case report.

There are numerous reports on the effects of the coronavirus disease on mothers and fetuses during pregnancy. It is currently unknown whether pregnancy is associated with a high risk of severe coronavirus disease. We report a pregnant patient with coronavirus disease who underwent a cesarean section. A pregnant 39-year-old Japanese woman was diagnosed with coronavirus disease at 25 weeks of gestation. Her breathing condition worsened daily, and she required oxygen administration. On day 6 of her 26th week of gestation, she developed severe pneumonia and required tracheal intubation and artificial ventilation, and an emergency cesarean section was performed under general anesthesia. It is necessary to investigate the risk of increased coronavirus disease severity during pregnancy, the effects of coronavirus disease on perinatal prognosis, and the management of pregnancy with coronavirus disease.

Prenatal diagnosis of fetal skeletal dysplasia using 3-dimensional computed tomography: a prospective study.

BACKGROUND: Fetal skeletal dysplasia (FSD) comprises a complex group of systemic bone and cartilage disorders. Many FSD phenotypes have indistinct definitions, making definitive prenatal diagnosis difficult. The condition is typically diagnosed using sonography; however, three-dimensional computed tomography (3D-CT) also aids in making a prenatal diagnosis. This study aimed to examine the efficacy of 3D-CT in the prenatal diagnosis of FSD by comparing the diagnostic accuracy of fetal sonography and 3D-CT. METHODS: On suspicion of FSD based on ultrasound examination, we performed 3D-CT prenatally to obtain detailed skeletal information on FSD. To minimize exposure of the fetuses to radiation without compromising image quality, we used predetermined 3D-CT settings for volume acquisition. RESULTS: Nineteen fetuses were suspected of having skeletal dysplasia based on ultrasonography findings. Of these, 17 were diagnosed with FSD using 3D-CT. All 17 fetuses diagnosed with FSD prenatally were confirmed postnatally to have the condition. The postnatal diagnosis (campomelic dysplasia) differed from the prenatal diagnosis (osteogenesis imperfecta) in only one infant. Sixteen cases (94.1%) were diagnosed both prenatally and postnatally with FSD. Five infants had lethal skeletal dysplasia; one died in utero, and four died as neonates. We determined the appropriate delivery method for each infant based on the prenatal diagnosis. CONCLUSIONS: 3D-CT is a valuable tool for augmenting ultrasound examinations in the diagnosis of FSD. While improving the diagnostic tool of sonography is essential in cases of suspected FSD, 3D-CT imaging is indispensable for diagnosis and classification, enabling better planning for resuscitation of the infant after birth.

Increased ipsilateral uterine artery vascular resistance in women with ovarian endometrioma.

AIM: The aim of this study was to elucidate whether the presence of an ovarian endometrioma is associated with impaired vascular flow. We investigated changes in vascular flow on the ipsilateral and contralateral side of the endometrioma, before and after surgery. METHODS: This prospective case-control study included 144 women (ovarian endometrioma [n = 40], endometriosis without ovarian endometrioma [n = 33], non-endometriotic ovarian cyst [n = 17], and normal pelvis [n = 54]). The uterine artery (UtA) vascular resistance indices (pulsatility index [PI] and resistance index [RI]) were measured using transvaginal Doppler sonography, and UtA diameters were measured using magnetic resonance imaging. RESULTS: The UtA PI and RI were significantly higher on the ipsilateral side of the endometrioma than on the contralateral unaffected side in the endometrioma group (P < 0.01), as well as in the non-endometriotic ovarian cyst group (P < 0.05), and normal pelvis group (P < 0.01). The UtA PI and RI on the ipsilateral side of the endometrioma were significantly lower after cystectomy than before cystectomy (P < 0.01). The UtA diameters were significantly larger (P < 0.01) on the ipsilateral side of the endometrioma than on the contralateral side. CONCLUSION: The UtA-vascular resistance might be higher on the ipsilateral side of the endometrioma than on the contralateral unaffected side, indicating a risk of subclinical atherosclerosis in women with endometriosis.

Telediagnosis system for congenital heart disease in a Japanese prefecture.

PURPOSE: This study aimed to evaluate the accuracy of prenatal diagnosis using a spatio-temporal image correlation-based telediagnosis system at a tertiary referral unit in a Japanese prefecture over a 9-year period, and to investigate the validity of delivery hospital selection. METHODS: This study retrospectively analyzed telediagnosis cases from 2009 to 2018 in six geographically remote hospitals. We built a telediagnosis system called the Kyoto Fetal Ultrasonographic Telediagnosis System (K-FUTS). Three-dimensional ultrasonographic images from these referral hospitals were forwarded to the Kyoto Prefectural University of Medicine (KPUM) Hospital through an optical fiber network system for analysis. The primary endpoint was accuracy of prenatal diagnosis. Cases with severe congenital heart disease (CHD) that required immediate postnatal treatment were identified using the K-FUTS. These cases were then examined to determine whether they were delivered at appropriate hospitals. RESULTS: During the study period, datasets from 182 cases were transferred to KPUM Hospital. Twenty-one datasets were excluded because of data unavailability or poor image quality. CHD was detected in 14.9% of cases (24/161); the accuracy of prenatal diagnosis was 95.0% (153/161). The K-FUTS identified seven severe cases with CHD requiring immediate postnatal surgical or medical treatment. These cases were delivered at KPUM Hospital with a pediatrician present. The remaining 17 cases considered suitable for delivery at the referral hospitals were delivered there, and they did not require intervention immediately after birth. CONCLUSION: Our telediagnosis system contributed to the prenatal diagnosis of CHD and management of pregnancies in patients who were geographically remote from a tertiary hospital.

A Case of Fetal Tachycardia after Electroconvulsive Therapy: A Possible Effect of Maternal Hypoxia and Uterine Contractions.

Electroconvulsive therapy (ECT) is considered to be an effective and safe treatment for depression in pregnant women in that it avoids the risk of psychotropic pharmacotherapy. However, clinicians should be cautious about the adverse effects in the fetus, such as fetal cardiac arrhythmia. Most of the previous studies have demonstrated a reduction in fetal heart rate associated with ECT. However, we encountered a case of fetal tachycardia after maternal ECT-induced convulsions. The patient was a woman who was 30 weeks' pregnant and had severe depression; fetal tachycardia (180-200 bpm) occurred immediately after the electrical stimulation and lasted for more than 30 minutes. The fetal tachycardia might have been caused by maternal hypoxia and uterine contractions. To our knowledge, this is the first report of fetal tachycardia as an adverse effect of ECT. Prolonged fetal tachycardia may cause fetal heart failure. Therefore, oxygenation during convulsions and careful fetal cardiac monitoring are essential when administering ECT in pregnancy.
