Comparison of single versus multiple courses of antenatal betamethasone in patients with threatened preterm labor.

PURPOSE OF INVESTIGATION: To compare single versus multiple courses of antenatal betamethasone administration with regards to the morbidity and mortality of preterm neonates. METHODS: One-hundred and twenty-two women with threatened preterm labor were allocated to three different betamethasone schedules: 1) two doses of betamethasone 12 mg, intramuscularly, 24 hours apart (standard treatment) (n = 41); 2) standard treatment plus a third dose of 12 mg after seven days (n = 41); and, 3) standard treatment plus one dose of 12 mg every seven days until delivery (n = 40). Neonatal morbidity and mortality as well as maternal morbidity were evaluated. RESULTS: Neonatal parameters, such as frequency of respiratory distress syndrome, intraventricular hemorrhage, necrotizing enterocolitis, sepsis and neonatal mortality were not significantly different among the three groups for both singleton and multiple pregnancies. Similarly, maternal parameters were not significantly different among the three groups. CONCLUSION: The administration of multiple betamethasone courses in threatened preterm labor is not superior to single courses with regards to neonatal morbidity and mortality, as well as to maternal morbidity.

Hormone therapy for postmenopausal endometrial cancer survivors: a survey among Greek obstetricians-gynaecologists.

PURPOSE OF INVESTIGATION: In this study we evaluated the prescription attitude of Greek obstetricians-gynaecologists towards hormone replacement therapy (HRT) for endometrial cancer survivors. METHODS: An anonymous questionnaire was sent to 900 members of the Hellenic Society of Obstetrics and Gynaecology, presenting a hypothetical case of an endometrial cancer survivor with indications for HRT, followed by a series of relevant questions. RESULTS: Three hundred and three valid responses were received and analysed according to age, gender and practice setting. HRT would be prescribed by 30.4% of gynaecologists; as far as type of regimen is concerned, 67.4% would prescribe tibolone, 22.8% estrogen-only and 9.8% estrogen plus progestagen. In contrast, 69.6% would not prescribe HRT due to the fear of endometrial cancer recurrence (88.2%), development of breast cancer (2.8%) or both (4.7%); among them, 28.4% would prescribe central nervous system (CNS) medications, selective estrogen receptor modulators (SERMs), phyto-oestrogens or biphosphonates, as alternates. CONCLUSIONS: One out of three Greek gynaecologists would prescribe HRT to endometrial cancer survivors. Alternative therapies, mainly CNS medications, would be suggested by the opposers.

Human placental lactogen and color Doppler in predicting expulsion of retained adherent placenta: a new clinical observation.

PURPOSE: To present a new clinical observation made in three cases of retained adherent placenta, a rare obstetrical complication, associated with potentially life-threatening hemorrhage. METHODS: Three consecutive cases of retained adherent placenta are presented. RESULTS: Diagnosis of placenta increta in two and placenta percreta in one case was established with ultrasound and MRI. Methotrexate 50 mg i.v. (300 mg total dose) and follinic acid 0.1 mg/kg were administered on alternating days, over 12 days. On follow-up, placental perfusion on color Doppler was present up to the point when circulating hPL levels were no longer detectable; this was followed in all cases by spontaneous placental expulsion within 10 days. CONCLUSIONS: The observation that both color Doppler and human placental lactogen can be used to monitor response to therapy and predict placental expulsion should be evaluated in future cases of retained adherent placenta.

Primitive neuroectodermal tumor (PNET) of the uterine isthmus.

Primitive neuroectodermal tumors (PNETs) of the uterus are very rare. The histogenesis of these tumors is still unknown and the differential diagnosis includes a wide variety of tumor entities. We describe a rare case of a 68-year-old female who presented with persistent vaginal bleeding. Physical examination and CT-scan revealed a large tumor in the uterus. Macroscopically the tumor involved the uterine isthmus. Histological and immunohistochemical examination showed that the tumor fulfilled the diagnostic criteria set for PNET. Only a very small number of cases of PNETs of the uterus have been reported in the literature, thus no definitive conclusions concerning the therapeutic management and prognosis have been ascertained.

Pelvic echinococcus mimicking multicystic ovary.

An unusual case of pelvic echinococcus cyst is presented, appearing initially on transvaginal ultrasound as a pelvic mass mimicking a multicystic ovary. A similar mass in the liver raised preoperatively the suspicion of echinococcosis, making an open surgical procedure preferable to laparoscopy. Diagnosis was confirmed pathologically after removal of the cyst. Though their location in the pelvis is rare, echinococcal cysts should be considered in the differential diagnosis of pelvic masses, especially in patients from endemic areas. Evaluation of previous medical history and current symptoms, together with the ultrasonographic findings, is important for correct diagnosis and appropriate management.

Elevated umbilical erythropoietin levels during labor in newborns of smoking mothers.

Umbilical cord blood erythropoietin levels and hematocrit are significantly higher in smoking mothers than those nonsmoking ones. In addition, the incidence of newborns with low birthweight is higher in women who smoke. We conclude that in addition to other parameters, cord blood erythropoietin might be used as a valuable indicator of fetal distress in smokers.
