Prenatal diagnosis of fetal multiple hemivertebrae: the importance of 3D ultrasound assessment.

We herein present a case of fetal multiple hemivertebrae detected at antenatal sonography. The use of the 3 D technology supported by a new contrast enhancement rendering algorithm (Crystal Vue) has allowed the accurate prenatal classification of the defect, confirmed at follow up, that would have been difficult to define by 2 D only.

Intracervical lakes as sonographic marker of placenta accreta spectrum disorder in patients with placenta previa or low-lying placenta.

OBJECTIVE: To evaluate the diagnostic accuracy of a new ultrasound sign, intracervical lakes (ICL), in predicting the presence of placenta accreta spectrum (PAS) disorder and delivery outcome in patients with placenta previa or low-lying placenta. METHODS: This was a retrospective multicenter study of women with placenta previa or low-lying placenta at ≥ 26 weeks' gestation, who were referred to three Italian tertiary units from January 2015 to September 2018. The presence of ICL, defined as tortuous anechoic spaces within the cervix which appeared to be hypervascular on color Doppler, was evaluated on ultrasound images obtained at the time of referral. The primary aim was to explore the diagnostic accuracy of ICL in detecting the presence and depth of PAS disorder. The secondary aim was to explore the accuracy of this sign in predicting total estimated blood loss, antepartum bleeding, major postpartum hemorrhage at the time of Cesarean section and need for Cesarean hysterectomy. The diagnostic accuracy of ICL in combination with typical sonographic signs of PAS disorder, was assessed by computing summary estimates of sensitivity, specificity, positive and negative predictive values, positive and negative likelihood ratios and diagnostic odds ratios (DOR). RESULTS: A total of 332 women with placenta previa or low-lying placenta were included in the analysis, with a median maternal age of 33.0 (interquartile range, 29.0-37.0) years. ICL were noted in 15.1% of patients. On logistic regression analysis, the presence of ICL was associated independently with major postpartum hemorrhage (odds ratio (OR), 3.3 (95% CI, 1.6-6.5); P < 0.001), Cesarean hysterectomy (OR, 7.0 (95% CI, 2.1-23.9); P < 0.001) and placenta percreta (OR, 2.8 (95% CI, 1.3-5.8); P ≤ 0.01), but not with the presence of any PAS disorder (OR, 1.6 (95% CI, 0.7-3.5); P = 0.2). Compared with the group of patients without ultrasound signs of PAS disorder, the presence of at least one typical sonographic sign of PAS disorder in combination with ICL had a DOR of 217.2 (95% CI, 27.7-1703.4; P < 0.001) for placenta percreta and of 687.4 (95% CI, 121.4-3893.0; P < 0.001) for Cesarean hysterectomy. CONCLUSION: ICL may represent a marker of deep villus invasion in women with suspected PAS disorder on antenatal sonography and anticipate the occurrence of severe maternal morbidity.

Los espacios intracervicales como marcador ecográfico de trastornos del espectro de la placenta acreta en pacientes con placenta previa o placenta baja OBJETIVO: Evaluar la precisión del diagnóstico de un nuevo indicio de ultrasonido, los espacios intracervicales (EIC), para predecir la presencia de trastornos del espectro de la placenta acreta (EPA) y el resultado del parto en pacientes con placenta previa o placenta baja. MÉTODOS: Este fue un estudio multicéntrico retrospectivo de mujeres con placenta previa o placenta baja a ≥ 26 semanas de gestación, que se remitieron a tres unidades terciarias italianas desde enero de 2015 a septiembre de 2018. Se evaluó la presencia de EIC, definida como espacios anecoicos tortuosos dentro del cuello uterino que parecían ser hipervasculares en el Doppler a color, en imágenes de ecografías obtenidas en el momento de la remisión. El objetivo principal fue estudiar la precisión del diagnóstico mediante EIC en la detección de la presencia y la profundidad de un trastorno del EPA. El objetivo secundario fue explorar la precisión de este indicador para predecir la pérdida total estimada de sangre, la hemorragia antes del parto, la hemorragia puerperal importante en el momento de la cesárea y la necesidad de una histerectomía por cesárea. La precisión diagnóstica de EIC, en combinación con los indicios ecográficos típicos de los trastornos del EPA, se evaluó calculando estimaciones estadísticas descriptivas de la sensibilidad, la especificidad, los valores predictivos positivos y negativos, los cocientes de verosimilitud positivos y negativos y las razones de momios del diagnóstico (RMD). RESULTADOS: En el análisis se incluyó un total de 332 mujeres con placenta previa o placenta baja, con una mediana de la edad materna de 33,0 años (rango intercuartil, 29,0-37,0). Se observaron EIC en el 15,1% de las pacientes. En el análisis de regresión logística, la presencia de EIC se asoció de forma independiente con la hemorragia puerperal grave (razón de momios (RM), 3,3 (IC 95%, 1,6-6,5); P<0,001), la histerectomía por cesárea (RM, 7,0 (IC 95%, 2,1-23,9); P<0,001) y la placenta percreta (RM, 2,8 (IC 95%, 1,3-5,8); P≤0,01), pero no con la presencia de ningún trastorno del EPA (RM, 1,6 (IC 95%, 0,7-3,5); P=0,2). En comparación con el grupo de pacientes sin indicios de ultrasonido de algún trastorno del EPA, la presencia de al menos un indicio ecográfico típico de trastorno del EPA en combinación con EIC tuvo una RMD de 217,2 (IC 95%, 27,7-1703,4; P<0,001) para la placenta percreta y de 687,4 (IC 95%, 121,4-3893,0; P<0,001) para la histerectomía por cesárea. CONCLUSIÓN: Los EIC pueden representar un marcador de invasión profunda de las vellosidades en mujeres con sospecha de algún trastorno del EPA basado en la ecografía prenatal y anticipar la presencia de una morbilidad materna grave.

Three-dimensional assessment of umbilical vein deviation angle for prediction of liver herniation in left-sided congenital diaphragmatic hernia.

OBJECTIVES: To introduce a new sonographic marker of intrathoracic liver herniation in fetuses with left-sided congenital diaphragmatic hernia (CDH). METHODS: In a consecutive series of fetuses with isolated CDH, an ultrasound volume of the fetal abdomen was acquired. On this volume, offline calculation of the angle formed by the midline of the abdomen (joining the center of the vertebral body to the abdominal insertion of the umbilical cord) and a second line joining the center of the vertebral body to the intra-abdominal convexity of the umbilical vein was carried out to give the umbilical vein deviation angle (UVDA). The UVDA was measured in a group of normal fetuses selected as controls. At follow-up, the presence of liver herniation was investigated in all cases of CDH. UVDA values were compared between the CDH group and controls, and between CDH 'liver-up' vs 'liver-down' cases. A receiver-operating characteristics (ROC) curve was constructed to identify a cut-off value of the UVDA with the highest accuracy in predicting liver herniation in the CDH group. RESULTS: Between 2009 and 2015, 22 cases of left-sided CDH were included in the study group, of which nine cases had liver herniation. Eighty-eight normal fetuses were recruited as controls. The UVDA was significantly higher in the cases vs controls (15.25 ± 7.91° vs 7.68 ± 1.55°; P < 0.0001). Moreover, the UVDA was significantly increased in CDH fetuses with liver-up vs liver-down (21.77 ± 8.79° vs 10.75 ± 2.10°; P < 0.0001). On ROC curve analysis the UVDA showed good prediction of liver herniation (area under the ROC curve, 0.94; P < 0.0001) with the best cut-off of 15.2°, yielding a sensitivity of 89% and a specificity of 100% (P < 0.0001). CONCLUSIONS: In fetuses with CDH, umbilical vein bowing may be quantified by measuring the UVDA using three-dimensional ultrasound. This sonographic marker seems to be an accurate predictor of liver herniation in left-sided CDH. Copyright © 2017 ISUOG. Published by John Wiley & Sons Ltd.

Abdominal or vaginal hysterectomy for enlarged uteri: a randomized clinical trial.

OBJECTIVE: The purpose of this study was to compare advantages, disadvantages, and outcomes in patients who undergo vaginal or abdominal hysterectomy for enlarged symptomatic uteri. STUDY DESIGN: In a prospective, randomized study, 60 vaginal hysterectomies (study group) were compared with 59 abdominal hysterectomies (control group); all of the hysterectomies were performed for symptomatic uterine fibroids from January 1997 through December 2000. We excluded from the study the other common causes of hysterectomy such as prolapse, bleeding, adenomyosis, and endometrial or cervical carcinoma. In both groups, uterine weights ranged from 200 g to 1300 g. For enlarged uteri, vaginal hysterectomies were performed with the use of volume reduction techniques: Intramyometrial coring, corporal bisection, and morcellation. The evaluated parameters included patient age, weight, parity, uterine weight, operative time, blood loss, demand for analgesics, eventual surgical complications, length of admission, and hospital charges. The Mann-Whitney U test and chi(2) tests were applied for statistical analysis. Probability values of <.05 were considered statistically significant. RESULTS: There were no major differences in patient age, weight, parity, and uterine weight between the two groups. Operative time was significantly lower for the vaginal route as compared with the abdominal route (86 minutes vs 102 minutes, P <.001). No intraoperative complications were noted both in the study and control groups or the control group. Surgical bleeding (expressed by hemoglobin loss) was not significantly different between the two groups. In the postoperative period, we found a higher incidence of fever (30.5% vs 16.6%, P <.05) and demand for analgesics (86% vs 66%, P <.05) in the abdominal group as compared with the vaginal group. Significant advantages of vaginal hysterectomy were a reduction in the hospital stay (3 days vs 4 days, P <.001) and cost. CONCLUSION: These results should lead to the choice of vaginal hysterectomy as a valid alternative to the abdominal hysterectomy, even for enlarged uteri.

Risk of genital prolapse and urinary incontinence due to pregnancy and delivery. A prospective study.

BACKGROUND: Recent literature shows conflicting results regarding this subject. Using a prospective study, we analysed the possible effects of pregnancy and delivery upon the pelvic floor support. METHODS: In a group of 344 patients who received our phone-call 3 months after delivery, only 58 accepted the investigation, and came for an exam. We looked out for pathologies such as genital prolapse and stress urinary incontinence (IUS). During the exam we analysed: vagino-perineal scars; descensus of the vaginal walls and of the uterus; dyspareunia; urinary frequency and urgency; urge Incontinence and IUS; weakening of pelvic floor muscles. RESULTS: We objectively identified in cystocele the prevalent "anatomic" damage, and in IUS, the most frequent "functional" damage. We then tried to find a statistical correlation between these pathologies and the most important risk factors cited in the literature. CONCLUSIONS: Through the systematic analysis of the obtained data, we thus identified the most important risk factors that lead to the development of these pathologies: operative delivery, pluriparity, heavy work, high BMI in mothers and newborns. The results that emerged from our study lead to some remarks of interest and discussion.

[Perinatal morbidity and mortality in children born to mothers with gestational hypertension]. / Morbilità e mortalità perinatali in nati da madri affette da ipertensione gestazionale.

Gestational hypertension is a severe pathology leading to important maternal and neonatal effects. It represents one of the most important causes of maternal morbidity and contributes to a high percentage of perinatal mortality, determined by fetal hypoxia and especially by prematurity and low birth weight. To-date the only treatment offered in gestational hypertension remains delivery, which has to be scheduled regarding timing and method on the basis of the appearance of hypertension, of its severeness and maternal and fetal complications. To evaluate the clinical course and the presence of hypertensive risk factors, a clinical-epidemiological study was carried out on two groups of pregnant women: a group made up of 50 women with hypertension and a control group of 80 women in whom no gravidic pathology arose. We hence were able to reveal the risk factors associated with hypertension in pregnancy such as maternal age, nulliparity, and elevated body mass index. Regarding neonatal prognosis, we observed a higher incidence in premature birth (30th- to 38th week of gestational age) and the need for elective or urgent caesarean sections, with respect to the spontaneous deliveries observed in the control group. We also observed reduced weight of both placenta and the newborn in hypertensive mothers with significant statistical differences between the two groups (p < 0.001). Evaluation of neonatal data at birth showed lower Apgar indices at 1st and 5th minute from birth in the study group with a higher percentage of newborns transferred to the neonatal intensive care unit. We also observed a high percentage of still-births equal to 14% in the study group as opposed to the control group.

[Evaluation of the peripartum effects of 2 analgesics: meperidine and tramadol, used in labor]. / Valutazione degli effetti peripartum di due analgesici, meperidina e tramadolo, utilizzati in travaglio di parto.

The need for analgesia to overcome pain in labour is highly requested by women today. Various ways either non pharmachologic e.g. Emotional sustain, psycho-prophylactic preparation, yoga and hypnosis or pharmachologic such as epidural blockade or parenteral are used. Therefore in our study we evaluated the efficacy and tolerability of the two opioids usually used today in parenteral analgesia to reduce pain during labour: Tramadol and Meperidine. We studied two groups of patients each made up of 20 women in labour, all at term and with a physiologic course of pregnancy. 75 mg i.m. of Meperidine chloryhydrate were somministered in the first group while in the second group 100 mg i.m. of tramadol chloryhydrate were somministered. Various maternal, fetal and neonatal parameters were then monitored demonstrating--A moderate maternal analgesic effect in both drugs (evaluated through the analogic grading of pain). In the group to whom Meperidine was given, sedative effects on the mother were observed associated with respiratory depression in the newborn (the latter evaluated through the Apgar index at 1st and 5th minute of life and pH of the blood obtained at the umbilical cord. The data obtained permitted us to conclude that Tramadol in accordance to the obtained in literature gives an analogous analgesic effect, with better tolerability for the absence of collateral effects on the mother, fetus and newborn.

[Lavage of the birth canal with chlorhexidine: a new valid method for the prevention of perinatal infections]. / Il lavaggio del canale del parto con clorexidina: una nuova valida metodica di prevenzione delle infezioni perinatali.

Perinatal morbidity and mortality are due to various infective agents, mainly represented by beta-hemolytic group B Streptococcus. The perinatal disease related to this infection is distinguished in Early-onset, characterised by pneumonia and sepsis, and Late-onset which leads to sepsis, meningitis and pneumonia. Various strategies were therefore proposed to prevent transmission including immunisation and chemoprophylaxis. All these methods however present adverse effects and are most of all expensive to carry out. Taha et al. reported an interesting experience regarding the reduction of perinatal infections following the cleansing of the birth canal with a solution of Chlorhexidine 0.25% during labour (1996-1997). It seemed interesting for us to assess the applicability and efficacy of a new strategy of prophylaxis of perinatal infections in a Developing Country based on the association of two of the simple strategies proposed i.e.: cleansing the birth canal with chlorhexidine and chemoprophylaxis in cases with risk factors without culture screening. We studied two groups of patients: one in which cleansing of the birth canal was used and the second (control group) in which the old method already applied in the hospital (i.e. cleansing of the external genitals with Cetrimide 1%+ Chlorhexidine 0.1%) was carried out associated with antibiotic therapy when risk factors arose. We observed a total absence of neonatal mortality due to sepsis resulting from the association of the methods suggested even though the presence of sepsis evaluated through signs and symptoms like fever, poor feeding, apnoea or dyspnoea in newborns was similar in both groups.
