ABSTRACT
Abruptio placenta can be a catastrophic event with a high association with adverse maternal and fetal outcomes. We present a case of massive abruptio placenta occurring in a young asymptomatic mother at 30 weeks' gestation. Although electronic fetal monitoring and ultrasound allowed a prompt diagnosis of an 8 × 5â cm retroplacental hematoma, the fetus died at the time of emergency cesarean section. The fetus was intubated, but could not be resuscitated. Histologic examination of the placenta documented thinning and stacked hypercapillarized villi, with syncytial buds and foci of fibrinoid necrosis in the presence of hyaline streaks on both the maternal and fetal sides.

Occult cervical cancer is rare and is diagnosed incidentally after a simple hysterectomy. The staging upon histological examination is usually International Federation of Gynecology and Obstetrics (FIGO) stage I, rarely higher with negative preoperative diagnostic tests such as a Pap smear. The clinical case in question is a rare case of cervical carcinoma diagnosed at the time of hysterectomy with a negative exo-endocervical Pap smear, diagnostic tests including transvaginal ultrasound, abdominal magnetic resonance imaging and abdominal computed tomography with a diagnosis of degenerating myoma or suspected sarcoma. In the operating theatre, the surgical radicality was modified and the operation was completed with removal of the parameters, vaginal collar and bilateral pelvic lymphadenectomy. The final histological examination indicated FIGO stage III, for which the patient underwent radiotherapy and chemotherapy.

BACKGROUND: Preterm birth is the leading cause of neonatal death and handicap in survivors. Although twins are found in 1.5% of pregnancies they account for about 25% of preterm births. Randomized controlled trials in singleton pregnancies reported that the prophylactic use of progestogens, cervical cerclage and cervical pessary reduce significantly the rate of early preterm birth. In twin pregnancies, progestogens and cervical cerclage have been shown to be ineffective in reducing preterm birth. OBJECTIVE: The objective of this study was to test the hypothesis that the insertion of a cervical pessary in twin pregnancies would reduce the rate of spontaneous early preterm birth. STUDY DESIGN: This was a multicenter, randomized controlled trial in unselected twin pregnancies of cervical pessary placement from 20(+0)-24(+6) weeks' gestation until elective removal or delivery vs. expectant management. Primary outcome was spontaneous birth <34 weeks. Secondary outcomes included perinatal death and a composite of adverse neonatal outcomes (intraventricular haemorrhage, respiratory distress syndrome, retinopathy of prematurity or necrotizing enterocolitis) or need for neonatal therapy (ventilation, phototherapy, treatment for proven or suspected sepsis, or blood transfusion). Analysis was by intention to treat. This trial is registered in the ISRCTN registry, number 01096902. RESULTS: A total of 1,180 (56.0%) of the 2,107 eligible women agreed to take part in the trial; 590 received cervical pessary and 590 had expectant management. Two of the former and one of the latter were lost to follow up. There were no significant differences between the pessary and control groups in rates of spontaneous birth <34 weeks (13.6% vs. 12.9%; relative risk 1.054, 95% confidence interval [CI] 0.787-1.413; p=0.722), perinatal death (2.5% vs. 2.7%; relative risk 0.908, 95% CI 0.553-1.491; p=0.702), adverse neonatal outcome (10.0 vs. 9.2%; relative risk 1.094, 95% CI 0.851-1.407; p=0.524) or neonatal therapy (17.9% vs. 17.2%; relative risk 1.040, 95% CI 0.871-1.242; p=0.701). A post hoc subgroup analysis of 214 women with short cervix (≤25 mm) showed no benefit from the insertion of a cervical pessary. CONCLUSION: In women with twin pregnancy, routine treatment with cervical pessary does not reduce the rate of spontaneous early preterm birth.

OBJECTIVE: To assess the sonographic visualization of the pericallosal arteries in normal fetuses at 11-13 weeks of gestation using 3D ultrasound. METHODS: We prospectively enrolled women with a singleton pregnancy undergoing ultrasound at 11-13 weeks of gestation. A 3D volume with high-definition power Doppler was acquired starting from the sagittal view of the fetal head and stored in the spatiotemporal image correlation mode. The images of the pericallosal arteries were assigned a score of 0 (no visualization), 1 (visualization of the origin) or 2 (visualization of the whole course). A follow-up scan was performed in all cases at 20 weeks of gestation to assess the presence of the corpus callosum. RESULTS: 70 patients were included and the pericallosal arteries were sonographically detectable in all cases. Image scores of 1 and 2 were obtained in 8 and 62 cases, respectively. The whole length of the vessel was between 3.5 and 4.5 mm. The vast majority of those with a score of 2 were beyond 12 completed weeks of gestation. All fetuses showed a normal corpus callosum at midtrimester and no abnormal brain findings after birth. CONCLUSIONS: The pericallosal arteries are sonographically visible since the first trimester in 3D ultrasound scans of fetuses found to have a normal corpus callosum at follow-up.

OBJECTIVE: To standardize the evaluation of normal tentorium insertion and normal rotation of the cerebellar vermis over the brainstem, using two novel measurements: the brainstem-tentorium angle (BT angle) and the brainstem-vermis angle (BV angle). We also aimed to test the reproducibility of these measurements. METHODS: Prospective observational study including normal fetuses at routine anomaly scan with confirmed normal follow-up. Three-dimensional volumes of the fetal head were acquired starting from standard trans-cerebellar views. In the sagittal plane, obtained by multiplanar reconstruction, the angle between the brainstem and the tentorium insertion in the fetal skull, and between the brainstem and the lower edge of the vermis were measured twice by two independent operators. Intraobserver and interobserver variations were calculated. RESULTS: Eighty cases were included. The estimated BT and BV angles lie in a wide interval among normal midtrimester fetuses with a median value (min-max) of 25.65 (20.13-47.39) and 9.29 (3.87-19.36) respectively. Intraobserver and interobserver variation were good for both measurements. CONCLUSION: The BT and BV angle may be of help in assessing the fetal posterior fossa at midgestation and gives a standardized and reproducible measurement of normal tentorium insertion and normal rotation of the cerebellar vermis over the brainstem.
