OBJECTIVE: Preterm labor is one of the most significant obstetric problems associated with high rate of actual and long-term perinatal complications. Despite the creation of scoring systems, uterine activity monitoring, cervical ultrasound and several biochemical markers, the prediction and prevention of preterm labor is still a matter of concern. The aim of this study was to examine cervical findings for the prediction and the comparative use of Arabin pessary or cerclage for the prevention of preterm birth in asymptomatic women with high risk factors for preterm labor...

BACKGROUND: Impaired healing of the uterine scar after cesarean has been associated with adverse gynecological and obstetric outcomes. Although a large number of studies have been conducted on the events leading to this, information obtained from prospective randomized studies examining the role of suture material in the formation of cesarean scar defect (CSD) is lacking. OBJECTIVE: To evaluate the effects of synthetic suture materials on CSD formation. STUDY DESIGN: We performed a two-arm 1:1 randomized study in women with singleton pregnancies undergoing elective primary cesarean delivery after the 38th week of gestation...

Over the past decade, ultrasound simulators have been increasingly used as an adjunct to clinical training in Obstetrics and Gynaecology. Studies have shown that providing initial simulation-based ultrasound training leads to sustained improvements in clinical performances1 including improved diagnostic accuracy,2 reduced need for supervised practice, and decreased patient discomfort.3 .

Ultrasound has become a core skill in many specialties. We evaluated the learning and assessment of ultrasound skills in Obstetrics-Gynaecology in a series of eight studies. In the clinical setting, we found that trainees as well as experienced clinicians struggle with technical aspects of performance such as image optimization. We examined how to improve these aspects of performance in the simulated setting by determining mastery learning levels and exploring learning curves for novices. We then examined how to improve the efficiency of training as well as transfer of learning through the use of dyad practice as compared with single practice...

OBJECTIVE: Twin pregnancy is associated with 2-3 fold increased risk of stillbirth compared to singletons. Despite the fact that the growth pattern has been shown to differ in twins compared to singletons, it is controversial whether twin-specific growth charts should be routinely used. A major goal of prenatal ultrasound is to identify fetuses suffering from growth restriction at risk of stillbirth. The main aim of this study was to compare the performance of chorionicity-specific twin charts with singleton charts, both customized and non-customized, in the antenatal prediction of small-for-gestational age (SGA) stillborn and liveborn fetuses...

BACKGROUND: Assessment of pelvic configuration is an important factor in the prediction of a successful vaginal birth. However, manual evaluation of the pelvis is practically a vanishing art, and imaging techniques are not available as a real time bed side tool. Unlike the obstetrical conjugate diameter (OC) and inter spinous diameter (ISD), the pubic arch angle (PAA) can be easily measured by transperineal ultrasound. OBJECTIVES: Three dimensional computed tomography bone reconstructions were used to measure the three main birth canal diameters, evaluate the correlation between them and establish the normal reference range for the inlet, mid- and pelvic outlet...

BACKGROUND: Perianal fistula surgery can damage the anal sphincters which may cause faecal incontinence. By measuring regional pressures, 3D-HRAM potentially provides better guidance for surgical strategy in patients with perianal fistulas. The aim was to measure regional anal pressures with 3D-HRAM and to compare these with 3D-EUS findings in patients with perianal fistulas. METHODS: Consecutive patients with active perianal fistulas who underwent both 3D-EUS and 3D-HRAM at a clinic specialised in proctology were included...

Maternal red blood cell (RBC) alloantibodies can cause hemolytic disease of the fetus and newborn (HDFN). Although much is described about common antibodies associated with HDFN, management of a pregnancy complicated by a maternal rare antibody presents several challenges related to assessment of fetal anemia risk, availability of blood for transfusion to the mother and/or the fetus or newborn if needed, and planning for delivery in the case of maternal hemorrhage. Here we report the laboratory medicine workup of a patient who presented for obstetrical care in the United States in the third trimester and had a rare antibody (anti-Inb)...

OBJECTIVES: Intra-abdominal adhesions may result in an increased risk of major complications in case of a repeated cesarean section, such as bladder and bowel injury, hemorrhage, infection, and hysterectomy. In an attempt to predict intra-abdominal adhesions before a repeated cesarean delivery, we suggest the use of a novel technique employing a simple and feasible ultrasound imaging technique. METHODS: The study included pregnant women who underwent one or more cesarean deliveries in their obstetric history and were evaluated during the third trimester of the ongoing pregnancy...

Obstetric anal sphincter injury (OASI) is the most common cause of anal incontinence and ano-rectal symptoms in women1 . Reported rates of anal incontinence following primary repair of OASI range between 15-61%, with a mean of 39%2, 3 . Other possible complications of OASI include perineal pain, dyspareunia, and less commonly, abscess formation, wound breakdown, and rectovaginal fistulae. Symptom onset may occur immediately, several years postpartum, or only late in life when aging of tissues adds to the delivery insult...

INTRODUCTION: Lemierre's syndrome (LS) is a rare and life-threatening condition characterized by suppurative thrombophlebitis of the internal jugular vein (IJV), and a history of head and neck (H&N) sepsis. LS is usually caused by Fusobacterium necrophorum, which is part of the normal flora in the oro-pharynx, and the digestive and urogenital tracts. We here report the first case of LS following perianal sepsis. PRESENTATION OF CASE: A 60-year-old man with a painful left neck swelling, dysphagia and worsening sepsis was referred from a peripheral unit where he had an incision and drainage of a perianal abscess a week earlier...

Congenital imperforate hymen is probably the most common obstructive anomaly of the female reproductive tract. The accumulation of fluid in the genital tract leads to a distended uterus and vagina, causing hydrometrocolpos. Prenatal diagnosis of fetal hydrometrocolpos is uncommon, with only 22 cases reported in the literature and only a few cases of prenatal imaging of this condition available to date. The main ultrasound finding is a fetal pelvic mass posterior to the bladder and anterior to the rectum. We present the case of a 37-week female fetus with a fetal pelvic mass detected in a routine obstetric ultrasound examination, and the correlation between the prenatal and postnatal findings...

REVIEW
Marie-Therese I Valovska, Vernon M Pais
Urolithiasis is the most common nonobstetric complication in the gravid patient. The experience can provoke undue stress for the mother, fetus, and management team. The physiologic changes of pregnancy render the physical exam and imaging studies less reliable than in the typical patient. Diagnosis is further complicated by the need for careful selection of imaging modality in order to maximize diagnostic utility and minimize obstetric risk to the mother and ionizing radiation exposure to the fetus. Ultrasound remains the first-line diagnostic imaging modality in this group, but other options are available if results are inconclusive...
