Preterm birth (PTB) is one of the major health-care challenges of our time. Being born too early is associated with major risks to the child with potential for serious consequences in terms of life-long disability and health-care costs. Discovering how to prevent PTB needs to be one of our greatest priorities. Recent advances have provided hope that a percentage of cases known to be related to risk factors may be amenable to prevention; but the majority of cases remain of unknown cause, and there is little chance of prevention...

INTRODUCTION: One of the functional parameters that can be assessed by ultrasound is muscle strain. Strain represents the amount of deformation from its original shape when forces are applied to the tissue under study. We set out to assess the global strain of the puborectalis muscle during and after pregnancy. OBJECTIVE: To evaluate the effect of pregnancy and child-delivery on global strain of the puborectalis muscle. METHOD: This is a secondary analysis of a prospective observational study on the association between stress urinary incontinence and levator muscle avulsion after delivery...

A rare case of parasitic myoma mimicking an adnexal mass in a previously hysterectomized, postmenopausal woman is presented. Two years after vaginal hysterectomy (due to myomas), an asymptomatic right adnexal tumor was noted during regular annual follow up. Ultrasound demonstrated a large 4-5 cm solid mass in the right adnexa, while ovarian cancer biomarkers (CA 125 and HE4) were negative. Intraoperatively, another 3 cm large solid tumor located above the vaginal cuff was discovered. Both pelvic tumors were excised by laparoscopic surgery...

Introduction At term, fetal weight estimation is an important factor for decisions about the delivery mode and the timing of labor induction. This study aimed to compare the accuracy of abdominal palpation with that of ultrasound performed by different examiners to estimate fetal weight. The study investigated whether differences in the examiners' training affected fetal weight estimates. The accuracy of the weight estimates made for fetuses with extreme birth weights was also evaluated. Finally, the accuracy of Johnson's method and of Insler and Bernstein's formula for estimating fetal weight were compared with the other two methods...

A G3P2 patient who conceived with an intrauterine contraceptive device (IUD) presented at 20 weeks of gestation with mild irregular uterine contractions and vaginal bleeding. Sonographic examination at admission showed the presence of dense amniotic fluid "sludge" and a long sonographic uterine cervix (42 mms). To assess the microbiologic significance of amniotic fluid "sludge", we performed a transabdominal amniocentesis. The procedure was performed under real-time ultrasound, and fluid resembling pus at gross examination was noted...

Epithelioid leiomyoma of the vagina is extremely rare. Smooth muscle tumors of the vagina usually present with a submucosal growth pattern or a pedunculated growth pattern from the anterior vaginal wall into the vaginal cavity. Here we report a case of a 43-year-old woman with a solid epithelioid leiomyoma and a palpable mass in the pouch of Douglas. Transvaginal biopsy and angiography showed the epithelioid leiomyoma feeding from the vaginal artery behind the posterior vagina. An abdominal wide excision of the tumor with a partial vaginectomy was performed...

The nonpregnant uterus is characterized by cyclic contractions that assist in sperm transport to the fallopian tube, embryo transport to implantation site, and expulsion of menstrual debris. The effect of post-Cesarean section (CS) scar on uterine peristalsis is unclear, while worldwide the prevalence of CS deliveries is increasing. In this study, we developed a new objective method for analysis of dynamic characteristics of the nonpregnant uterus from transvaginal ultrasound (TVUS) recordings when the uterine cavity is not clearly observed, as may be the case in post-CS uteri...

Ultrasound equipment used in trans-abdominal (TA) and trans-vaginal (TV) examination may carry bacterial contamination and pose risks to infection control during ultrasound examination. We aimed to describe the prevalence of bacterial contamination on ultrasound probes, gel, machine keyboard and cords and examined the effectiveness of low- and high-level disinfection techniques. This study was performed at a public hospital and a private practice. A total of 171 swabs were analyzed and bacterial species were identified using matrix-assisted laser desorption/ionization time-of-flight (MALDI-TOF) analysis and polymerase chain reaction (PCR)...

BACKGROUND: Safe management of the second stage of labor is of great importance. Unnecessary interventions should be avoided and correct timing of interventions should be focused. Ultrasound assessment of fetal position and station has a potential to improve the precision in diagnosing and managing prolonged or arrested labors. The decision to perform vacuum delivery is traditionally based on subjective assessment by digital vaginal examination and clinical expertise and there is currently no method of objectively quantifying the likelihood of successful delivery...
