Validation of the IOTA ADNEX Model Among Japanese Women Performed by Gynecology Trainees and Ultrasound Specialists: A Retrospective Diagnostic Accuracy Study.

OBJECTIVES: This study aimed to validate the diagnostic accuracy of the International Ovarian Tumor Analysis (IOTA) Assessment of Different NEoplasias in the adneXa (ADNEX) model in Japanese women, population with a distinct adnexal mass distribution compared with European women, and to evaluate the model's utility by gynecology trainees and ultrasound specialists. METHODS: This single-center, retrospective study analyzed ultrasound data from January 2017 to March 2020 of 206 women with adnexal masses. Patients who underwent ultrasonography and serum CA-125 measurement and received postsurgery histological diagnosis were included. The ADNEX model's diagnostic performance was evaluated by two trainees and two specialists using the area under the receiver operating characteristic curve (AUC) and measures of accuracy, sensitivity, specificity, and predictive values for overall performance and each examiner. RESULTS: Of the 206 included Japanese women, the prevalence of malignancy was 30.1%, including borderline cases. The overall AUC for distinguishing malignancy was 0.848 (95% confidence interval [CI]: 0.817-0.880). The AUC for each examiner ranged from 0.791 to 0.898, with Specialist 2 showing the highest accuracy and sensitivity varying between 0.677 and 0.839. A moderate degree of agreement was noted among the four examiners (Fleiss' kappa was 0.586). The performance of trainees and specialists differed significantly in evaluating the solid tissue and the papillary projections in both malignant and benign groups (P < .001). CONCLUSIONS: The IOTA ADNEX model effectively differentiates benign and malignant adnexal masses in Japanese women. Although the accuracy matched up moderately among the four examiners, better accuracy is expected with training in evaluating solid tissue and papillary projections.

Telemedicine for home care of fetal growth restriction with mobile cardiotocography: A case series.

OBJECTIVE: Modern technological advancements have made it possible to perform cardiotocography at home. Home-based management of high-risk pregnancies using a mobile cardiotocography system has been reported; however, its effectiveness in monitoring cases of fetal growth restriction (FGR) remains unclear. Therefore, the authors aimed to investigate the clinical usefulness of home-based telemedicine for FGR management using the mobile cardiotocography (iCTG). METHODS: The authors conducted a single-center, retrospective case series of patients with FGR. Seventeen women diagnosed with FGR were enrolled. Patients performed iCTG for 1 hour twice daily to examine their fetuses; data were uploaded and saved on the cloud. RESULTS: The median and minimum compliance rates were 93.33 (interquartile range [IQR], 70.00-100.00) and 40.7, respectively. The median and minimum validity rates were 100.00 (IQR, 90.48-100.00) and 36.4, respectively. In this study, many of the patients were managed at home and underwent delivery as planned. However, three patients required emergency visits; one had a nonreassuring fetal status and underwent an emergency cesarean section. CONCLUSION: Even when the fetal prognosis is good, careful pre-evaluation is required before initiating home care management. The current study shows that the economic burden of hospitalization for patients can be reduced by using iCTG.

Isolated Agnathia-Otocephaly Complex Diagnosed Prenatally for Ex-Utero Intrapartum Treatment: A Case Report.

BACKGROUND Agnathia-otocephaly complex (AOC) is a rare congenital malformation due to a first-branch arch disorder and has been considered lethal. However, milder variants of the isolated type of AOC have been reported as nonlethal. The ex-utero intrapartum treatment (EXIT) procedure is basically indicated for a fetus with a high risk of airway obstruction immediately after birth; it is not indicated for all AOC cases but is chosen to treat cases until the airway can be evaluated to achieve a better prognosis. CASE REPORT A 37-year-old woman was referred with reported fetal facial deformity and polyhydramnios at 27 weeks of gestation. Our fetal ultrasound scans showed agnathia, microstomia, and synotia, but not holoprosencephaly. Isolated AOC was diagnosed prenatally. Magnetic resonance imaging and microbubble tests revealed delayed fetal lung maturation, although it was not completely unmatured. With patient agreement, an emergency cesarean section with EXIT was performed because of clinical chorioamnionitis at 35 weeks of gestation. Tracheostomy was attempted for 16 min during EXIT and was completed 4 min after delivery. Despite this, the neonate died 12 h after delivery from severe respiratory failure and a tension pneumothorax caused by a hypoplastic lung. CONCLUSIONS There is controversy surrounding the non-lethality of all isolated AOC cases and the non-contraindication of EXIT procedures. Our case was estimated as the milder variant, and the EXIT procedure was indicated; however, the neonate died of the hypoplastic lung. The evaluation methods of lung maturation are inconsistent, and the indication of the invasive EXIT procedure must be carefully considered.

Long-term survival of a patient with stage IIIC2 grade 3 endometrioid endometrial carcinoma treated with surgery alone.

BACKGROUND: The therapeutic benefit of lymphadenectomy in endometrial carcinoma is controversial. CASE: A 70-year-old woman with grade 3 endometrioid endometrial carcinoma with deep myometrial invasion underwent surgical staging comprising total abdominal hysterectomy, bilateral salpingo-oophorectomy, peritoneal cytology, and pelvic and para-aortic lymphadenectomy. Pathological examination revealed micro-metastases in the para-aortic node, pelvic node, and left ovary. Peritoneal cytology was negative, and abnormal p53 expression was not detected. The patient was diagnosed with stage IIIC2 endometrial carcinoma. Adjuvant chemotherapy was advised, but the patient refused chemotherapy and was followed up regularly thereafter. The patient survived without any evidence of disease 67 months after surgery. CONCLUSION: Pelvic and para-aortic lymphadenectomy may have a therapeutic benefit in a patient with high-grade endometrioid carcinoma, but without p53 abnormality.

Intrapartum Subarachnoid Hemorrhage from Suspected Lateral Posterior Choroidal Artery Dissection.

Stroke associated with pregnancy or puerperium is rare, but represents an important problem for women of childbearing age. We herein report a case of subarachnoid hemorrhage (SAH) due to suspected lateral posterior choroidal artery (LPChA) dissection during delivery. A 34-year-old woman developed deterioration of consciousness during delivery at a maternity clinic. Her Glasgow Coma Scale score was E3V3M6. She was sent to our hospital after 12 hr, where CT revealed SAH with intraventricular hematoma. Radiographic examinations showed contrast pooling on the left LPChA. Repeated angiography showed enlargement of the contrast pooling, which indicated pseudoaneurysm. It also showed a relatively clear but stenosed LPChA communicated with the lesion which could not be recognized in the angiography on day 0. This stenosed LPChA indicated arterial dissection. Therefore, endovascular parent artery occlusion was performed on day 11. Determining the exact extent of dissection was difficult because the LPChA was extremely narrow. Occlusion of the posterior cerebral artery was needed to achieve complete hemostasis, which, however, resulted in infarction of the medial temporal and occipital lobes. At the time of final follow-up 3 years later, the patient was alert and completely independent, but showed persistent incomplete homonymous hemianopsia. We reported a rare case of SAH from suspected LPChA dissection during delivery. Repeated angiography provided information about the source of hemorrhage and definite diagnosis, which opened the way to treatment. It is also important to recognize the difficulty in identifying the exact extent of dissection when treating dissections of small arteries.

Effect of neonatal hemoglobin concentration on long-term outcome of infants affected by fetomaternal hemorrhage.

BACKGROUND: Fetomaternal hemorrhage (FMH) can cause severe morbidity. However, perinatal risk factors for long-term poor outcome due to FMH have not been extensively studied. AIMS: To determine which FMH infants are likely to have neurological sequelae. STUDY DESIGN: A single-center retrospective observational study. Perinatal factors, including demographic characteristics, Kleihauer-Betke test, blood gas analysis, and neonatal blood hemoglobin concentration ([Hb]), were analyzed in association with long-term outcomes. SUBJECTS: All 18 neonates referred to a Neonatal Intensive Care Unit of Kagoshima City Hospital and diagnosed with FMH during a 15-year study period. All had a neonatal [Hb] <7.5g/dL and 15 of 17 neonates tested had Kleihauer-Betke test result >4.0%. OUTCOME MEASURES: Poor long-term outcome was defined as any of the following determined at 12 month old or more: cerebral palsy, mental retardation, attention deficit/hyperactivity disorder, and epilepsy. RESULTS: Nine of the 18 neonates exhibited poor outcomes. Among demographic characteristics and blood variables compared between two groups with poor and favorable outcomes, significant differences were observed in [Hb] (3.6±1.4 vs. 5.4±1.1g/dL, P=0.01), pH (7.09±0.11 vs. 7.25±0.13, P=0.02) and base deficits (17.5±5.4 vs. 10.4±6.0mmol/L, P=0.02) in neonatal blood, and a number of infants with [Hb]≤4.5g/dL (78%[7/9] vs. 22%[2/9], P=0.03), respectively. The base deficit in neonatal arterial blood increased significantly with decreasing neonatal [Hb]. CONCLUSIONS: Severe anemia causing severe base deficit is associated with neurological sequelae in FMH infants.
