胎児骨系統疾患は新生児期早期に管理を要する疾患であるが,超音波検査での胎児診断の精度は高くはない。今回,Three-dimensional computed tomography(以下,3D-CT)が胎児診断に有用であった胎児骨系統疾患の3例を経験したため報告する。症例1は妊娠16週より胎児骨系統疾患が疑われ,超音波検査で極めて予後不良な疾患が想定されたが,妊娠継続を希望され胎児3D-CTを撮像した。画像所見から骨形成不全症II型を強く疑い,分娩時損傷を回避するために帝王切開で出生した。症例2,3は妊娠27週頃より顕著な四肢の短縮を認め,胎児3D-CTによりそれぞれ骨形成不全症,軟骨無形成症と胎児診断した。3症例とも出生後速やかに新生児集中治療室(Neonatal Intensive Care Unit;NICU)に入室し,呼吸管理や画像検査,遺伝子検索などの早期介入につながった。胎児3D-CTは鑑別診断や重症度の診断精度が上がり,予後や治療方針を両親に事前に情報提供でき,かつ周産期管理指針が明確になる点で有用な検査であると考えられた。(著者抄録)

BACKGROUND: A subsequent pregnancy after uterine artery embolization (UAE) raises several concerns, one of which is placenta accreta spectrum (PAS). Placenta previa is the strongest risk factor for PAS, which is most likely to occur in the lower uterine segment. PAS without placenta previa (i.e., uterine body PAS) is considered relatively rare. CASE PRESENTATION: A 35-year-old woman, gravida 2 para 1, had undergone UAE for postpartum hemorrhage due to uterine atony after vaginal delivery in her previous pregnancy. She developed placenta previa during her subsequent pregnancy and was therefore evaluated for PAS in the lower uterine segment. On the basis of examination findings, we considered PAS to be unlikely. During cesarean section, we found that the placenta was not detached from the uterine body, and the patient was determined to have uterine body PAS. Ultimately, a hysterectomy was performed. CONCLUSIONS: PAS can occur in a subsequent pregnancy after UAE. When a subsequent pregnancy after UAE is accompanied by placenta previa, it is important to maintain a high index of suspicion of uterine body PAS without being misled by the presence of placenta previa.

AIM: We aimed to grasp the actual working hours of Japanese obstetricians and gynecologists (OB/GYN doctors) as accurately as possible, using the same method of the Ministry of Health, Labour, and Welfare (MHLW). METHODS: The time study targeted OB/GYN doctors working at 10 universities nationwide including Niigata University and 21 institutions which take a role of perinatal care in Niigata prefecture. Working hours per week were calculated based on the following categories: regular and overtime work inside the hospital, work outside the hospital, self-improvement, education, research, and others. Data on weekly working hours were converted to yearly data for analyses. RESULTS: A time study of 10 universities nationwide revealed that 30% of doctors work overtime for more than 1860 h even if they do not include on-call shifts in their working hours. In 21 institutions in Niigata, physicians in Niigata University worked more overtime than other hospitals. It became clear that community health care was supported by dispatching physicians working at university. Furthermore, the results of simulations predicted the pessimistic situation of perinatal medical care in Niigata. CONCLUSIONS: Our study showed the possibility to exist much more OB/GYN doctors who work more than 1860 h of overtime work per year than the data presented by the MHLW based on nation-wide survey in 2019. The fact that the working hours at the side jobs had a great influence on the increase in overtime work of physicians in University was the same result as the report of MHLW published in 2021.

Background Our previous study demonstrated the safety and effectiveness of abdominal radical trachelectomy during pregnancy but did not focus on the fetus. This study aimed to clarify the influence of abdominal radical trachelectomy performed during pregnancy on the fetus. Methods Eight cervical cancer patients who underwent abdominal radical trachelectomy at our hospital between February 2013 and August 2020 were enrolled in this study. To assess the peri- and postoperative influence on the fetus, we performed fetal heart monitoring at 30-min intervals during abdominal radical trachelectomy and calculated the estimated fetal body weight and resistance indexes of the middle cerebral artery and umbilical artery from postsurgery until delivery. Results Four out of eight patients had preterm birth due to chorioamnionitis in one case and consideration of the recurrent risk of cervical cancer in three cases. Fetal heart monitoring during abdominal radical trachelectomy revealed deceleration just once in one case but no abnormal findings in the other cases. In all cases, the fetal growth after abdominal radical trachelectomy was normal until delivery. No abnormal Doppler findings were detected in the middle cerebral artery or umbilical artery. Conclusion Our findings clarified that abdominal radical trachelectomy performed for the treatment of early-stage cervical cancer during pregnancy has no obvious influence on fetal growth. Next, it is necessary to evaluate the growth and development of children delivered from mothers who have undergone abdominal radical trachelectomy during pregnancy.

BACKGROUND: Patients with systemic lupus erythematosus (SLE) are associated with pre-eclampsia. Pre-eclampsia can have systemic manifestations, such as ascites. Lupus peritonitis, a rare condition in patients with SLE, can also cause ascites. CASE PRESENTATION: A 31-year-old woman, primigravida, with SLE had a blood pressure of 170/110 mmHg and proteinuria at 29 weeks of gestation. She was diagnosed with pre-eclampsia. Her blood pressure was stabilized by an antihypertensive drug. At 30 weeks of gestation, a cesarean section was performed for maternal safety because of decreased urine output and massive ascites. Postoperatively, re-accumulation of ascites was observed. On the fourth postoperative day, ascites (approximately 3 L) was discharged from the cesarean section wound. A decrease in serum complement concentrations was observed, and she was diagnosed as having lupus peritonitis. The steroid dose was increased and she recovered well thereafter. CONCLUSIONS: Ascites occurs in pre-eclampsia and SLE, but determining which of these conditions causes ascites can be difficult. However, careful observation is necessary because of the differences in treatment of these two conditions.

We conducted a retrospective analysis on the clinical backgrounds and patient outcomes of 52 cases of congenital gastrointestinal atresia encountered in our institution in the past 28 years. These cases were divided into three groups: esophageal, duodenal, and intestinal atresia. Our evaluation revealed that the rate of polyhydramnios was significantly lower in the intestinal atresia group, but there was no significant difference in the rate of threatened preterm labor or preterm birth among all groups. Esophageal atresia had the highest perinatal mortality rate and the poorest neonatal prognosis. Conversely, there were no reported cases of chromosomal abnormalities in the intestinal atresia group, which had a good prognosis. Collectively, the prenatal diagnosis rate was 77% for all cases. Polyhydramnios as observed on ultrasonography, along with the appearance of gastric bubbles and bowel dilatation, and the use of fetal MRI all contributed to the prenatal diagnosis. However, when compared among groups, prenatal diagnosis and the accuracy of diagnostic rates by fetal MRI were significantly lower for esophageal atresia. Our analysis showed that ultrasonography and fetal MRI are useful tools for prenatal diagnosis of congenital gastrointestinal atresia, even though diagnosis is challenging in some cases. Since prenatal or postnatal prognosis depends on the site of the gastrointestinal tract obstruction, prenatal diagnosis has the significance of providing appropriate information to expectant parents, managing pregnancy, and facilitating neonatal treatment.

Lamellar body is a surfactant-containing lamellar structure secreted from type II alveolar epithelial cells, and Lamellar body count（LBC）is used to estimate surfactant production in utero and to predict fetal lung maturity. We conducted this study to evaluate the neonatal respiratory status at 36-38 weeks of gestation using LBC. 127 Amniotic fluid were analyzed immediately with no centrifugation and the number of lamellar bodies was counted using a platelet channel on the Sysmex KX-21.12 neonates（9.4%）had respiratory disorders and 115（90.4%） did not. The LBC in respiratory disorders group was significantly lower than in control group（2.7×10⁴/μL vs. 6.0×10⁴/μL; p<0.001）. The optimal cut off value to predict neonatal respiratory disorders was 4.4×10⁴/μL（area under the curve 0.833, 95% confidence interval 0.702-0.963）, with a sensitivity of 91.7%, specificity 69.6%, positive predictive value 26.2% and negative predictive value 94.1%. The LBC in vaginal delivery cases was significantly higher than in caesarean section cases（8.0×10⁴/μL vs. 5.3×10⁴/μL; p=0.036）. LBC is a useful method that is very simple, rapid, objective, and accurate in detecting neonatal respiratory disorders cases.

The clinical outcomes of dinoprostone vaginal insert and mechanical methods for cervical ripening were compared retrospectively. The duration of labor and the time taken for hospital discharge were significantly shorter in the vaginal group than in the mechanical group. Mothers in the vaginal group had a significantly higher percentage of deliveries within 24 hours of vaginal insertion of dinoprostone than those in the mechanical group. In cases in which labor was induced at 37 or 38 weeks’ gestation due to maternal complications, there were no cases in either group in which use was discontinued due to worsening complications. Moreover, the time taken for hospital discharge was significantly shorter in the vaginal group, indicating the usefulness of dinoprostone vaginal insert in patients with maternal complications. On the other hand, uterine tachysystole and fetal dysfunctions may occur while administering dinoprostone vaginal inserts; therefore, careful management and compliance with the directions for use is necessary.

AIM: The Ministry of Health, Labour, and Welfare of Japan proposed a regulation of overtime work as a reform in work style. However, the regulation may deteriorate the quality of medical services due to the reduction in training time. Thus, the study aimed to reveal perceptions in terms of generation gaps in views on self-training and overtime work, among members of the Japan Society of Obstetrics and Gynecology (JSOG). METHODS: A web-based, self-administered questionnaire survey was conducted among members of the JSOG. In total, 1256 respondents were included in the analysis. Data were collected on age, sex, experience as a medical doctor, location of workplace, work style, the type of main workplace, and number of full-time doctors in the main workplace. The study examined the attitudes of the respondents toward overtime work and self-training. The respondents were categorized based on experience as a medical doctor. RESULTS: According to years of experience, 112 (8.9%), 226 (18.0%), 383 (30.5%), 535 (42.6%) doctors have been working for ≤5, 6-10, 11-19, and ≥ 20 years, respectively. Although 54.5% of doctors with ≤5 years of experience expected the regulation on working hours to improve the quality of medical services, those with ≥20 years of experience expressed potential deterioration. After adjusting for covariates, more years of experience were significantly related with the expectation of deterioration in the quality of medical services. CONCLUSIONS: The study revealed a generation gap in the views about self-training and overtime work among obstetricians and gynecologists in Japan.

Purpose: The Hospital Anxiety and Depression Scale (HADS) is a self-report questionnaire widely used to assess anxiety and depression. To the best of our knowledge, only four studies have examined the factor structure of the HADS for assessing pregnant women, with conflicting results. This study aimed to assess the factor structure and measurement invariance of the HADS for use with pregnant Japanese women. Participants and Methods: A total of 936 pregnant Japanese women completed the HADS questionnaire at three time points: the first and third trimester of pregnancy, and postpartum. We examined the factor structure of the HADS in Group 1 (n = 466) using exploratory factor analysis (EFA). We then compared the models identified in Group 1 with those from previous studies using confirmatory factor analysis (CFA) in Group 2 (n = 470). We performed multiple-group CFA for Group 2 to test the measurement invariance of the best-fit model across the three time points. Results: The EFA for the Group 1 data at the three time points revealed a two-factor model. In the CFA, the two-factor model from Group 1 showed the best fit with the data at the three time points. In the multiple-group CFA for Group 2, we confirmed the configural and metric invariance of the two-factor model across the three time points. Conclusion: Our findings provide evidence for a two-factor structure and weak measurement invariance of the HADS in pregnant Japanese women during the peripartum period.

Purpose: Postpartum depression is a well-known risk factor, and postpartum anxiety and parity are potential risk factors, for mother-infant bonding disorder. However, few studies have focused on the relationships among these factors and mother-infant bonding. This cross-sectional study explored the associations between depression, anxiety and parity, and mother-infant bonding. Materials and Methods: Japanese mothers, both primiparas and multiparas, completed the Mother-to-Infant Bonding Scale (MIBS) and the Hospital Anxiety and Depression Scale (HADS) one month after childbirth. We performed a stepwise multiple regression analysis with the forward selection method to assess the effects of HADS anxiety and depression scores and parity as independent variables on mother-infant bonding as the dependent variable. Results: A total of 2379 Japanese mothers (1116 primiparas and 1263 multiparas) took part in the study. MIBS score (2.89 ± 2.68 vs 1.60 ± 2.11; p < 0.0001) was significantly higher in primiparas than in multiparas. HADS anxiety (6.55 ± 4.06 vs 4.63 ± 3.41; p < 0.0001) and depression (6.56 ± 3.43 vs 5.98 ± 3.20; p < 0.0001) scores were also significantly higher in primiparas than in multiparas. A stepwise multiple regression analysis with the forward selection method revealed that HADS depression and anxiety scores and parity were significantly associated with MIBS score (p = 0.003, 0.015 and 0.023). Conclusion: Depression, anxiety and primiparity were negatively associated with mother-infant bonding one month after childbirth.

The vernix caseosa is a complex membranous structure comprising 80% water, 10% protein, and 10% lipids including barrier lipids such as ceramides, free fatty acids, phospholipids and cholesterol, synthesized partly by fetal sebaceous glands during the last trimester of pregnancy in an antero-posterior and dorsoventral manner. Because of its lipid content, vernix is hydrophobic and protects the skin from excessive water exposure during the development of the stratum corneum. The vernix caseosa has various functions during fetal transition from an intrauterine to an extrauterine environment, including lubrication of the birth canal during parturition, barrier function to prevent water loss, temperature regulation, for innate immunity and for intestinal development. This review discusses the evidence supporting the prenatal and postnatal functions of vernix caseosa, along with its structure, composition, and physical and biological characteristics. Understanding the biology of the vernix may facilitate improved care of preterm infants immediately post-partum.

帝王切開後の術後創部感染(SSI)、特に子宮筋切開部SSIや子宮創部膿瘍を予防するため感染性滲出液の貯留を防ぐことの重要性に着目し、効果的な排液法としてドレーン挿入の有効性の有無と適切なドレーンの挿入法について検討した。まず、感染性滲出液の効果的な排液法を、in vitroの帝王切開術後モデルを作成して検討した。帝王切開術後モデルの作成には鶏肉とヨーグルトを用い、鶏肉を子宮下節の筋層縫合後の子宮筋層のモデル、感染性滲出液の代用にヨーグルトを使用した。膀胱子宮窩腹膜を縫合し、閉鎖式吸引ドレーンを挿入した「膀胱子宮窩腹膜縫合モデル」が最も効率よく滲出液を排液した。「無縫合モデル」ではヨーグルトは少しずつ吸引されるが、「縫合モデル」と比べ効率が悪く、ヨーグルトの注入量が多くなると周囲に漏出した。そのため、適切に滲出液を排除するためには、ダグラス窩にもドレーンの挿入を要すると考えられた。開放式ドレナージ法では少量の排液を認めたが、滲出液を十分に排除することは困難であった。この結果を受け、2013年8月から絨毛膜羊膜炎等の感染を背景に有する症例(胎胞形成や前期破水など)のうち、緊急手術となった症例を対象とし、帝王切開時に、膀胱子宮窩腹膜を縫合し閉鎖式吸引ドレーンを挿入するドレナージ法を導入した。その結果、子宮筋層切開創の創部感染の発生率は0.32%に有意に低下し、腹壁の創部感染もドレナージ法導入前後で9例から1例に減少した。

Introduction: Primary spinal cord tumours can lead to severe neurological complications and even death. Pregnant women often complain of discomfort of the lower limbs, which is usually caused by sciatica. Here we present the case of a pregnant woman, who was initially considered to have sciatica, but was finally diagnosed with a primary intramedullary spinal cord tumour. Case presentation: A 28-year-old pregnant woman presented to our hospital with inexplicable numbness in her lower limbs. She was initially considered to have sciatica, but acute deterioration of neurological symptoms and plain magnetic resonance imaging (MRI) findings suggested malignancy. The patient was finally diagnosed with a primary intramedullary spinal cord tumour at the C3-Th5 region. An emergency caesarean section was performed, after which the spinal cord lesion was evaluated using contrast-enhanced MRI, positron emission tomography with 2-deoxy-2-[fluorine-18] fluoro-d-glucose integrated with computed tomography, and spinal angiography, and further treatment was initiated. However, while the patient's spinal cord tumour surgery was performed in early postpartum, her paraplegia and bladder and rectal disturbances remained unchanged even 1 year after surgery. Discussion: Because of the low incidence of spinal cord tumours during pregnancy, no definite reports have been published on the treatment of pregnant patients with spinal cord tumours. Although safe imaging tests during pregnancy are limited, intervention in such patients should be performed as early as possible to avoid irreversible neurological deterioration.

Objective: Severe motor vehicle accidents involving pregnant women can result in fetal and neonatal death. We describe a case in which fetal death occurred due to relatively mild seatbelt injuries and present the characteristic magnetic resonance imaging (MRI) findings of the placenta.
Case Report: A 26-year-old primigravid woman at 20 weeks gestation was involved in an automobile accident. Although she suffered only a seatbelt injury, fetal death subsequently occurred. Contrast enhanced MRI showed the region compressed by the seatbelt as a low-intensity band without enhancement, and serum alpha-fetoprotein and hemoglobin F levels were elevated.
Conclusion: Careful monitoring, including blood and abdominal examinations, should be performed when pregnant women suffer seatbelt injuries. (C) 2017 Taiwan Association of Obstetrics & Gynecology. Publishing services by Elsevier B.V.

26歳。自然妊娠し、経過順調であった。妊娠20週5日、軽自動車を時速50kmで運転中、対向車と正面衝突し車が横転するという事故を起こした。この時、3点式シートベルトを着用しており、エアバッグが作動した。1時間後に当院に救急搬送された。来院時、右肩と両側上前腸棘部にシートベルト痕を認めた以外は体表面に目立った外傷はなく、腹痛や性器出血、破水も認めなかった。超音波検査でも母体の心タンポナーデや血胸、腹腔内出血などのいわゆるFAST(focused assessment with sonography for trauma)は陰性であった。一方、胎児心拍は50〜60/分と徐脈を呈しており、事故から1時間半後に消失し、子宮内胎児死亡が確認された。その原因検索目的で施行したMRIの所見などから、原因として、1)交通事故に起因する物理的な圧迫に伴う常位胎盤早期剥離、2)胎盤実質の損傷と胎盤内の血管破綻に伴う急激な胎盤機能不全、3)胎児母体間輸血などが考えられた。また、胎盤尾側の損傷がシートベルトに沿うように帯状を呈していたことから、シートベルトによる胎盤への強い衝撃が一連の誘因であったと推測された。

非瘢痕子宮破裂の4症例を提示した。症例1(35歳)、症例3(32歳)、症例4(31歳)は3回以上の分娩を経験しており、症例1、症例2(35歳)、症例4では促進剤を使用していたことから、全ての症例でリスクファクターを有していたことになる。また、4症例において、幸いにも母体死亡は認めなかったが、2例で輸血を要し、3例で子宮摘出を余儀なくされた。症例1、2は分娩中に突然の児心音低下と強い腹痛が認められたため、常位胎盤早期剥離を疑い緊急帝王切開術を施行した。症例3、4はともに分娩中に明らかな異常は認められず、分娩後に症状が出現した。症例3は後腹膜血腫の疑い、症例4は弛緩出血を疑い、止血目的で開腹術を施行した。妊娠および分娩時の非瘢痕子宮破裂の診断は決して容易ではないが、今回経験した全4例において、その裂創はいずれも子宮体下部〜峡部の側壁の縦走が認められた。非瘢痕趾球破裂が疑われる場合、子宮体下部〜峡部の側壁に出血あるいは血腫を疑わせる低エコー領域が存在しないかを確認することにより、早期診断が可能となり、開腹の時機を逸しないものと考えられた。

In patients with fructose-1,6-bisphosphatase (FBPase) deficiency, maternal and fetal neurodevelopmental abnormalities can be induced by severe hypoglycemia and lactic acidosis, which is triggered by pregnancy. The patient was a 24-year-old and primipara. Via pre-pregnancy education and management including self-monitoring of blood glucose and prompt medical intervention with glucose infusions, she never experienced hypoglycemia with impaired consciousness. She delivered a 2,406 g male infant at 38 weeks of gestation by cesarean section. No neurological abnormalities in either the mother or the child appeared during the following 2 years. This is the first report with detailed descriptions of the management of a pregnant woman with FDPase deficiency. This report suggests that for a patient with FBPase deficiency, the maternal and fetal complications can be reduced by pre-pregnancy education and self-monitoring of blood glucose to prevent hypoglycemia.

Objective To determine the feasibility and safety of transverse fundal incision with manual placental removal in women with placenta praevia and possible placenta accreta.
Design Case series.
Setting Four level-three Japanese obstetric centres.
Population Thirty-four women with prior caesarean section and placenta praevia that widely covers the anterior uterine wall, in whom placenta accreta cannot be ruled out.
Methods A transverse fundal incision was performed at the time of caesarean section and manual placental removal was attempted under direct observation.
Main outcome measure Operative fluid loss.
Results The total volume of fluid lost during our operative procedure compares favourably with the volume lost during our routine transverse lower-segment caesarean sections performed in patients without placenta praevia or accreta. The average fluid loss was 1370g. No patients required transfer to intensive care, and there were no cases of fetal anaemia.
Conclusions This procedure has the potential to reduce the heavy bleeding that arises from caesarean deliveries in women with placenta praevia and placenta accreta.

No reports have described effects on the fetus of maternal jaundice caused by drug-induced hepatotoxicity during pregnancy, particularly in the first trimester. We report on two pregnant women who developed severe drug-induced hepatic failure and hyperbilirubinaemia during the period of fetal organogenesis. Both were diagnosed and treated promptly, and neither of the newborns had organic abnormalities. Prompt discontinuation of the drug suspected to be causing the condition is the optimal management, immediately decreasing the maternal bilirubin level and improving the perinatal prognosis. It appears that brief exposure of the fetus to maternal hyperbilirubinaemia during the first trimester may not affect fetal development, even if the mother's bilirubin level temporarily exceeds 171.0 μmol/l.

Nishijima K, Shukunami K, Yoshinari H, Takahashi J, Maeda H, Takagi H, Kotsuji F. Interactions among pulmonary surfactant, vernix caseosa, and intestinal enterocytes: intra-amniotic administration of fluorescently liposomes to pregnant rabbits. Am J Physiol Lung Cell Mol Physiol 303: L208-L214, 2012. First published May 25, 2012; doi: 10.1152/ajplung.00081.2011.-Although vernix caseosa is known to be a natural biofilm at birth, human pulmonary surfactant commences to remove the vernix from fetal skin into the amniotic fluid at gestational week 34, i.e., well before delivery. To explain this paradox, we first produced two types of fluorescently labeled liposomes displaying morphology similar to that of pulmonary surfactant and vernix caseosa complexes. We then continuously administered these liposomes into the amniotic fluid space of pregnant rabbits. In addition, we produced pulmonary surfactant and vernix caseosa complexes and administered them into the amniotic fluid space of pregnant rabbits. The intra-amniotic infused fluorescently labeled liposomes were absorbed into the fetal intestinal epithelium. However, the liposomes were not transported to the livers of fetal rabbits. We also revealed that continuous administration of micelles derived from pulmonary surfactants and vernix caseosa protected the small intestine of the rabbit fetus from damage due to surgical intervention. Our results indicate that pulmonary surfactant and vernix caseosa complexes in swallowed amniotic fluid might locally influence fetal intestinal enterocytes. Although the present studies are primarily observational and further studies are needed, our findings elucidate the physiological interactions among pulmonary, dermal-epidermal, and gastrointestinal developmental processes.

A Japanese girl with neonatal-onset chronic hepatitis and systemic inflammation was diagnosed with hyper-immunoglobulinemia D and periodic fever syndrome (HIDS). However, she lacked the typical HIDS features until the age of 32 months. She had compound heterozygous MVK mutations, H380R and A262P, the latter of which was novel. These findings suggest that HIDS patients could lack typical episodes of recurrent fever at the onset and that HIDS should be considered as a possible cause of neonatal-onset chronic hepatitis.

38歳(5回経妊2回経産婦)。患者は2回の帝王切開の既往と3回の流産手術の既往があった。今回、前置胎盤の妊娠管理を目的として、妊娠29週5日目に著者らの施設へ紹介入院となった。妊娠30週時のカラードプラ検査では、胎盤から子宮筋層、そして膀胱へ向かう、激しい血流が描出された。また、妊娠34週時のMRIでは膀胱と接する部分の子宮筋層が明らかではなく、胎盤の辺縁は不整で、膀胱への広範な絨毛浸潤が疑われた。以上より、妊娠35週5日目に選択的帝王切開術を行ったところ、子宮下部の腫大をはじめ膀胱子宮窩腹膜付近の血管怒張、漿膜下の胎盤透見が観察された。更に膀胱と子宮は強固に癒着し、1期的手術は困難と判断され、子宮底部横切開法にて2894gの女児が娩出された。以後、子宮筋切開創を縫合閉腹し、帝王切開術から27日目に子宮全摘出術と膀胱の処理が行われたが、膀胱の処理に際しては病的筋層を残したまま膀胱を縫合したため、術後一時的な縫合不全を生じた。だが、バルーンカテーテルを留置することで自然修復が得られ、目下は経過良好である。

動脈管早期閉鎖は胎児水腫や新生児遷延性肺高血圧症をきたし、以前はきわめて重篤な病態とされていた。しかし、近年では出生前診断も可能になり、出生後の早期対応によっては必ずしも予後不良でないことや軽症例が存在することが明らかになってきた。今回われわれは、動脈管早期閉鎖により新生児遷延性肺高血圧症をきたした1例を経験した。本症例では出生前に胸水貯留を認めており、胎内で右心不全がかなり進行していたと推測された。出生後、鎮静、経鼻的持続陽圧呼吸管理を併用した酸素投与、利尿剤、PDE III阻害剤投与を行った。日齢14の退院時には三尖弁逆流が軽度残存していたが、生後1ヵ月の時点ではそれも消失していた。本症例は出生前診断例ではなかったが、生後早期のうちに診断し適切な治療を施したことで重症化を抑止できたケースであると思われた。(著者抄録)

Endothelial cells produce nitric oxide (NO), a potent vasodilator. Asymmetric dimethylarginine (ADMA) is an endogenous inhibitor of NO synthase. Little is known about the potential physiological roles of ADMA in a perinatal setting. This study measures concentrations of ADMA in umbilical blood using enzyme-linked immunosorbent assay and those of NO as nitrite/nitrate (NOx(-)) using the Griess assay. Their relationship to the degree of prematurity and maternal clinical condition is examined. Results show that ADMA concentrations in umbilical blood from control newborns were about twice as high as those of lactating women, healthy children, and healthy adults. Umbilical blood NOx(-) concentrations from control newborns were about half of those of lactating women, healthy children, and healthy adults. Consequently, the levels of ADMA relative to NOx(-) were about 4-fold higher in umbilical blood from control newborns than in blood from lactating women, healthy children, and healthy adults. Furthermore, the umbilical blood ADMA concentrations and the ratios of ADMA to NOx(-) in newborns were higher according to their birth prematurity and lower birth weight. The umbilical ADMA concentrations were independent of the delivery mode and maternal preeclampsia. We infer that the high ADMA levels play physiological roles in maintaining vascular tone and blood redistribution to vital organs during birth, thereby favoring the circulatory transition from fetal to neonatal life.

Studies using in vitro analysis have shown that the interaction between pulmonary surfactant and vernix caseosa could explain the appearance of amniotic fluid turbidity. That phenomenon is interpreted based on the "roll-up" hypothesis. We tested the roll-up hypothesis by examining the presence of micelles of pulmonary surfactant in human amniotic fluid at term. Amniotic fluid samples were collected from each of six healthy pregnant women at term and at 16 wk of gestation. These samples were stained negatively and analyzed using an electron microscope. Ultrastructures present in amniotic fluid were compared with the structure of micelles derived from suspended surfactant TA isolated from bovine lung. Surfactant TA formed spheroidal and rod-shaped micelles 10-70 nm in diameter above the critical micelle concentration. Identical micelle particles were described in human amniotic fluid at term. In addition, surfactant protein B was identified in the micelle fraction of amniotic fluid. However, no micelles were found in human amniotic fluid taken at 16 wk of gestation. Our results support the view that pulmonary surfactant could induce the detachment of vernix caseosa and increase the turbidity of the amniotic fluid.

福井大学医学部で考案した開腹下癒着胎盤子宮温存手術を,帝王切開時に併施した症例を提示して紹介した.本術式のポイントは,1)子宮筋層に加える縦切開,2)子宮の翻転,3)オキシトシン製剤を投与しながらの胎盤剥離である.本法では子宮翻転により胎盤付着面を直視下に置くことができ,出血部位を直接確認できるため止血操作も容易である.癒着の弱い部位から順次剥離を進められるという利点もある.経腟分娩後に判明した癒着胎盤例も,開腹下に本法を行うことで安全に子宮温存が可能である.本術式は癒着胎盤のスタンダードを目指すものではないが,強度な癒着胎盤であっても子宮温存が可能な例もある.適応は限られるが,子宮摘出術を考慮しながら,その一歩手前で試みる価値がある方法と思われる

BACKGROUND: Control of bleeding is the goal of management for placenta accreta, which usually necessitates hysterectomy. A Committee Opinion of The American College of Obstetricians and Gynecologists (ACOG) has addressed the difficulties of conservative treatments.
CASES: Placentas of 2 primiparous women with placenta accreta were removed operatively from their uteri. One woman underwent a low transverse cesarean delivery, and the other had delivered vaginally. In each case, the anterior uterine wall was incised vertically between the lower segment and fundus before manual removal. After eversion of the uterus, the placenta was successfully detached from the wall after intramyometrial administration of oxytocin.
CONCLUSION: A vertical incision in die anterior uterine wall and subsequent eversion of the uterus may aid in avoiding with placenta accreta. (c) 2005 by The American College of Obstetricians and Gynecologists.

Objective. This study was intended to determine the relationship between the angle of the lower placental edge in early pregnancy and the previa/low-lying placenta at delivery.
Methods. We used transvaginal sonography to consecutively screen 2543 singleton pregnancies. All subjects were scanned during the period of gestation between 12 weeks 0 days and 15 weeks 6 days. The angle of the lower placental edge was measured when the placenta covered the internal cervical os. These cases were followed sonographically until term.
Results. Of 168 cases in which the internal cervical os was covered at screening, 9 showed previa/low-lying placenta at delivery (previa/low-lying group). The remaining 159 showed no abnormal placentation (nonprevia group). There were significantly fewer degrees of angle in the previa/low-lying group than in the nonprevia group (P &lt;.05). For the previa/low-lying group, the arithmetic mean, median, and SD values of the angles were 60.8degrees, 5.0degrees, and 9.8degrees, respectively. For the nonprevia group, those values were 103.4degrees, 103.0degrees, and 31.8degrees, respectively. Data based on the cutoff number of the angle of 74degrees indicated the following: sensitivity of placenta previa or low-lying placenta at term, 100% (9 of 9), false-positive rate, 23% (36 of 159), positive predictive value, 20% (9 of 45), and negative predictive value, 100% (123 of 123).
Conclusions. The angle between the placental-uterine interface and fetal placental surface can be evaluated during early pregnancy. It appears to accurately precict placenta previa or low-lying placenta at term gestation with a sensitivity of 100%, a false-positive ate of 23%, and a high negative predictive value of 100%, which would allow for elimination of some of the multiple scans.

Growing evidence indicates that oxidative stress occurs during the fetal-to-neonatal transition. Such stress plays an important role in the pathogenesis of many neonatal diseases. Thioredoxin (TRX), a redox-regulating protein with antioxidant activity, is induced in various cells against oxidative stress and is secreted extracellularly. This study was undertaken to examine the clinical and biological importance of TRX in the perinatal setting. We measured concentrations of TRX in umbilical cord blood and breast milk using a sandwich ELISA. Our study demonstrated that concentrations of TRX in umbilical cord blood were six to seven times higher than those in blood of healthy adults. This study also showed that umbilical concentrations of TRX were correlated significantly with the extent of prematurity of the newborn, and that they were elevated significantly in newborns of mothers with preeclampsia compared to those of mothers without preeclampsia. In contrast, concentrations of coenzyme Q(10) and vitamin E in umbilical blood were lower than adult blood levels. Breast milk concentrations of TRX during the early postpartum period were seven to eight times higher than those in blood of lactating women. Those of the coenzyme Q(10) were lower than adult blood levels, while those of vitamin E were comparable to adult blood levels. Our findings suggest that the systemic release of TRX is enhanced at birth, and that early breast milk is a rich source of this protein. Consequent high levels of TRX in newborns may provide a unique protective mechanism that allows the maintenance of redox balance during the fetal-to-neonatal transition.

Objective: To clarify resuscitation methods against the lethal vernix caseosa aspiration syndrome. Method: A single case report with a literature review. Results: Our case report was associated with aspiration syndrome caused by an airway obstruction of vernix caseosa: a proteolipid biofilm synthesized by the fetus. A 23-year-old woman normally delivered a mature infant at term. The infantile oral cavity was filled with numerous aggregates of vernix caseosa. Two hours after his birth, the infant died from respiratory insufficiency. We discuss the difference between management of our case and the previously reported case. Conclusion: Pregnant women with a diffuse pattern of high-level echoes in prenatal ultrasonography, suggesting the presence of massive vernix caseosa, should be transferred to a well-equipped institution that can administer inhaled nitric oxide and extracorporeal membrane oxygenation.

Massive subchorionic hematoma is a localized collection of blood or hematoma in the placenta, and can result in serious obstetrical complications. The condition can be diagnosed antenatally by ultrasound. However, no reports have previously described the same condition featuring an intraplacental fluid-fluid level on imaging studies. We report a case of massive subchorionic hematoma diagnosed prenatally, and propose an additional peculiar finding detectable on both the ultrasound and magnetic resonance images: the intraplacental fluid-fluid level. We also review previously reported cases that were detected by ultrasonography. Copyright (C) 2005 S. Karger AG, Basel.

In cases with placenta accreta occurring on the previous cesarean scar, a longitudinal incision is generally appropriate. However, the placenta may prevent both a longitudinal and lower transverse incision. We report a case of placenta increta on the previous cesarean scar, and discuss the role of transverse fundal uterine incision.

BACKGROUND: Detorsion and cystectomy of twisted adnexa have been performed in young women. However, identification was incomplete, and the function of the affected tube was not investigated.
CASE: A 23-year-old, nulligravid woman with an acute abdomen was diagnosed with adnexal torsion. An emergency laparotomy revealed that both ovaries were 12 x 9 x 9 cm. The right adnexa were twisted and bluish black. Detorsion of the twisted lesion and ipsilateral fallopian tube was performed, with subsequent cystectomy of both lesions. Hysterosalpingography on the 14th postoperative day showed right tubal obstruction; 6 months postoperatively, repeat hysterosalpingography revealed patency of the right tube.
CONCLUSION: At least several months may be required for functional recovery of an untwisted tube. For that reason, postoperative repeat hysterosalpingography is a useful method for follow-tip of function in an untwisted tube.

Subamniotic hematoma is a placental pathological lesion resulting from the rupture of allntochorionic vessels. Some of them decrease in size during pregnancy. However, the relation between the reduction of the lesions during pregnancy and the structure of the placenta at delivery has not been previously reported. We report a case of subamniotic hematoma detected prenatally, which decreased in size during the third trimester, and presented with a cystic structure resembling a deflated balloon at delivery, and also review the literature of the placental surface cysts detected by prenatal ultrasound.

胎児の健康診断に対して、医療現場で広く用いられている分娩監視装置は、超音波ドプラ信号を用いて胎児心拍の変動状態を監視している。胎児の健康状態をさらに詳細に調べるためには、瞬時心拍数の細変動解析が必要であるが、分娩監視装置では3〜4拍分のドプラ信号心拍周期値(RR時間と呼ぶ)を平均化して、BPM(一分間あたりの心拍数に換算して)で心拍数の値を表示している。そのため、細変動解析が難しいと言われているが、分娩監視装置のドプラ信号を用いた細変動解析能力を評価するために、平均的なドプラ信号のBPMをRR間隔時間を換算し、また、平均化される前の各々の瞬時ドプラ信号の心拍RR間隔時間データを直接用いて評価実験を行う。本研究では、これらのドプラ信号を用いた細変動解析能力を、心電図信号によるRR間隔時間(基準値とみなす)を用いて行った細変動解析値と対比して比較評価する。(著者抄録)

妊娠後期には羊水の濁りが急激に生じることが知られている。著者等は、この濁りは胎児の肺成熟に伴って産生された肺サーファクタントが胎脂を取り込んで&quot;分子集合体ミセル&quot;を形成し羊水に分散するための現象であることを明らかにした。本来生体の保護フィルムとして働く胎脂が妊娠後期に皮膚から剥がれ落ちる事実は、胎脂がそれ以外の役割を担っている可能性を示唆する。一方、乳汁中の主要なエネルギー源である長鎖脂肪酸は、腸管内で胆汁酸と反応し、ミセル構造をとることで消化管から吸収される。今回、胎児が嚥下する羊水と新生児が摂取する母乳の両者に&quot;分子集合体ミセル&quot;が存在するという点に着目し、超低出生体重児の初期管理に有効な経腸栄養剤の開発に向けた基礎的検討を行った。ウサギを用いて、独自に作製したサーファクテン・ミセル溶液を羊水腔内に持続投与し、胎仔の腸管成熟に及ぼす影響について検討した。その結果、本溶液は胎仔の小腸上皮に局所的に作用して腸管成熟を促すことが示唆された。
