Background: The Israeli Ministry of Health reported an increased rate of twin pregnancies among all cases locally diagnosed as having open neural tube defects. The current study aimed to evaluate whether the etiology of this phenomenon could be attributed either to the twinning or to the mode of conception.
Methods: Women admitted to our hospital between January 1997 and July 2004 for termination of pregnancy because of severe fetal abnormality enrolled into this retrospective case series study.
Background: The study aims to compare the diagnostic accuracy of sonographic evaluation versus clinical estimation in women suspected to have retained trophoblastic fragments.
Methods: The study group consisted of 68 consecutive patients admitted to our department due to suspected residual trophoblastic tissue. Each woman underwent ultrasound and physical examination by expert clinicians.

Objective: In order to better understand the etiology of the vulvar vestibulitis syndrome, we examined the histopathologic parameters in vestibular mucosa, and compared the findings in specimens obtained from women with vulvar vestibulitis with those obtained from the control group.
Study Design: Specimens of vestibulitis were obtained from 24 patients, undergoing circumferential vestibulectomy under general anesthesia due to the symptoms and signs consistent with vulvar vestibulitis. Control specimens were obtained from 16 women, without symptoms or signs of vulvar vestibulitis, undergoing reconstructive introital surgery due to roomy vagina, rectocele or painful episiotomy.
Objective: To compare outcome in women undergoing termination of multiple pregnancy as compared with singleton pregnancy at 18-24 weeks' gestation by Laminaria dilatation and evacuation.
Study Design: The medical records of 372 consecutive women undergoing does not increase pregnancy termination by Laminaria dilatation and evacuation at 18-24 weeks' gestation between January 1997 and December 2001 were reviewed and divided into a group with multiple pregnancies (38 cases) and a group with singleton pregnancies (334 cases). The 2 groups were then compared for differences in patient characteristics, indications for pregnancy termination and operative outcome.
Objective: To evaluate the efficacy of conservative management of ectopic pregnancy with fetal cardiac activity by combined local sonographically guided and systemic injection of methotrexate.
Study Design: The study group included 12 patients with ectopic pregnancy and fetal cardiac activity, treated by combined local and systemic injection of methotrexate in the period from January 1, 2000 to July 1, 2002. The outcome of these patients was compared with the outcome of 53 patients who had ectopic pregnancy without fetal cardiac activity and were being treated only by systemic injection of methotrexate during the same period of time.
Objective: To examine the operative outcome in women undergoing late midtrimester pregnancy termination by dilatation and evacuation in the presence of complete placenta previa.
Study Design: The records of 306 consecutive women undergoing pregnancy termination at 19-24 weeks' gestation from January 1997 to December 2000 were reviewed and divided into those with and without complete placenta previa based on an ultrasound examination before the procedure. These two groups were then compared for differences in patient characteristics, previous gynecologic history and operative outcome, reflected by operative time, need for blood transfusion, discharge time, postoperative bleeding and postoperative fever.
