Uterine rupture after prostaglandin analogues to induce midtrimester abortion.

Although prostaglandins are largely used and considered safe drugs to induce midtrimester abortion, the literature reports several cases of uterine rupture consequent to their administration. We report the second ever-described case of uterine rupture after administration of gemeprost and sulprostone for midtrimester abortion in a 45 years-old women with scarred uterus.She was admitted to our Unit for termination at 20 weeks' gestation because of trisomy 21 diagnosed by chromosomal analysis of amniotic liquid at 16 weeks' gestation. Five pessaries of gemeprost (one pessary, every 3 hours) were administered into the posterior vaginal fornix. Since the cervix remained closed and uneffaced, another cycle of 5 gemeprost administration was conducted. When the cervix changed in consistency and dilatation, we decided to administrate sulprostone. At the obstetric examination any visible fetus was evidenced. The abdominal ultrasonography showed an empty uterine cavity and the gestational sac with the dead fetus in abdomen. Emergency laparotomy was therefore undertaken. Primary suture of the ruptured uterus was initially attempted but in vain. Therefore, total abdominal hysterectomy was performed to control bleeding and eventual hypovolemic shock.Given the lack of strong evidence in literature and the fact that case reports are not an optimal method for assessing frequency of an event nor the overall risks of a procedure since they frequently report rare single events, other larger studies are needed to assess whether women with multiple risk factors (e.g. advanced age and previous uterine surgery), and administered with prostaglandins' association have a higher risk of uterine rupture.

Unilateral ovarian and fallopian tube agenesis.

INTRODUCTION: The unilateral agenesis of the ovary and fallopian tube is an extremely uncommon event with only few cases described in literature. CASE REPORT: Here, we report a case of a 30-year-old woman admitted to our Unit for increasing pelvic pain. In the suspect of a corpus luteum hemorrhage, we performed a laparoscopy identifying the rare anomaly. DISCUSSION: Together with the predisposing genetic and/or environmental factor not yet discovered, two are the hypotheses explaining the absence of one or both the adnexes, the mechanical hypothesis, i.e., the asymptomatic torsion of both Fallopian tube and ovary with consequent organs' ischemia and atresia and the embryological hypothesis, i.e., the congenital absence of the adnexes.

Fetal intracranial cysts: prenatal diagnosis and outcome.

Intracranial cysts are central nervous system malformations involving different brain regions, and commonly diagnosed during prenatal period by ultrasound scan (US). A malformative cyst is a nontumoral fluid-filled collection exerting a mass effect on the brain parenchyma and/or on the ventricles, regardless of its location within subarachnoid spaces, brain or ventricles, and of the nature of its limiting membrane, which is always unknown prenatally. Although a large number of case reports have been published, many uncertainties remain concerning their epidemiology, pathogenesis, and outcome. Most of these lesions, if not associated with other fetal anomalies, are benign in nature, remain clinically silent, do not evolve or even frequently regress spontaneously and do not impair physiologic neurodevelopment. The normality of the adjacent brain is the major argument in favour of a malformative lesion. The correct diagnosis is of crucial importance to exclude the presence of other rare lesions (e.g. cystic neoplasms or intracranial hemorrhage) that could negatively affect neurodevelopmental outcome of the child. To establish a correct prognosis all efforts must aim to precisely interpret the US images accurately analyzing the brain anatomy.

A prenatally diagnosed case of sirenomelia with dextrocardia and omphalocele.

OBJECTIVE: Sirenomelia (Mermaid syndrome) is a rare anomaly of caudal region of the body, presented with fusion of the lower limbs. Genito-urinary, gastro-intestinal, neural tube and vertebral anomalies are found in most cases. METHODS: We present a case of sirenomelia diagnosed in the first tri-mester, associated with dextrocardia, and omphalocele CONCLUSION: First trimester diagnosis of sirenomielia is possible and early diagnosis gives the parents the option of early pregnancy termination.

Abnormal skull findings in neural tube defects.

The human neural tube develops and closes during the third and fourth week after conception and is normally completed by 28 days post-conception. Malformations, knows as neural tube defects, occure, when the normal closure process fails. Several clinical types of neural tube defects are recognized, anencefaly and spina bifida being the most common. Such malformations are generally associated with cranial abnormlities.
