RESUMEN
OBJECTIVE: Cervical cerclage, when performed in twin gestation, has been reported to be associated with poor outcome. However, the role of first-trimester history-indicated cerclage among women with a twin pregnancy and a history of preterm birth has not been evaluated. The aim of this study was to assess pregnancy outcomes among women with a twin pregnancy who underwent first-trimester history-indicated cervical cerclage compared with outcomes in those managed expectantly. METHODS: This was a retrospective matched case-control study. The study group comprised all women with a twin pregnancy who had undergone first-trimester history-indicated cerclage during the period 2006 to 2017 at Hadassah-Hebrew University Medical Center. A control group of women with a twin pregnancy who were managed expectantly was established by matching age, history of spontaneous preterm birth (20-36 weeks' gestation) and year of delivery. Pregnancy and delivery characteristics and neonatal outcomes were compared between the two groups. RESULTS: Data from 82 women with a twin gestation were analyzed, of whom 41 underwent first-trimester history-indicated cerclage and 41 were matched controls who were managed expectantly. Gestational age at delivery was higher in the cerclage group than in those managed expectantly (median 35 vs 30 weeks; P < 0.0001). Rates of spontaneous preterm birth before 24 weeks (2.4% vs 19.5%; odds ratio (OR), 0.10 (95% CI, 0.01-0.87); P = 0.03), before 28 weeks (12.2% vs 34.1%; OR, 0.27 (95% CI, 0.09-0.84); P = 0.03), before 32 weeks (22.0% vs 56.1%; OR, 0.22 (95% CI, 0.08-0.58); P = 0.003) and before 34 weeks (34.1% vs 82.9%; OR, 0.11 (95% CI, 0.04-0.30); P < 0.0001) were significantly lower in the cerclage group than in the control group. Median birth weight was higher in the cerclage group (2072 g vs 1750 g; P = 0.003), with lower rates of low birth weight (< 2500 g) (65.0% vs 89.4%; P = 0.001) and very low birth weight (< 1500 g) (21.3% vs 37.9%; P = 0.03) than in the group managed expectantly. Rates were also lower in the cerclage group for stillbirth, admission to the neonatal intensive care unit, respiratory distress syndrome, intraventricular hemorrhage, necrotizing enterocolitis, sepsis, neonatal mortality and composite adverse neonatal outcome. CONCLUSIONS: History-indicated cerclage performed in the first trimester, as compared with expectant management, in women with a twin pregnancy had an overall positive effect on pregnancy and neonatal outcomes. These findings suggest the need for adequate randomized trials on cerclage placement in this subset of women. Copyright © 2018 ISUOG. Published by John Wiley & Sons Ltd.

OBJECTIVE: We compared pregnancy and delivery outcomes between women with cardiac disease versus matched healthy controls. The primary outcome was the frequency of unplanned cesarean delivery. METHODS: In this single-center retrospective case-control study, women with cardiac disease were identified and matched (1:2 ratio, according to maternal age, parity, number of prior cesareans, gestational age, delivery onset and fetal presentation) to healthy controls who delivered within the same year. Outcomes were frequency of unplanned cesarean delivery, complications during pregnancy and postpartum course, intensive care unit (ICU) admissions, and length of hospitalization. RESULTS: One hundred and twelve women with cardiac disease (exposed group, 225 deliveries) were identified and matched with 450 healthy women (controls, 2003-2014). The cohort comprised of 103 women (204 deliveries) with acquired heart disease (valve disease [n = 69], arrhythmia [n = 31], 3 with cardiomyopathy and peri/myocarditis, and 9 women (21 deliveries) with congenital heart disease. The frequency of unplanned cesarean was 14 (7.9%) for the exposed group as compared with 12 (3.4%) in controls with an odds ratio of 2.33 (95% CI = 1.0.2-5.32, p = .045). This difference was accentuated in a sub-group of women with severe cardiac disease (15% vs. 4.2% in matched control group, p = .028). Seventy-one (31.6%) exposed women exhibited obstetric and cardiovascular complications during pregnancy as compared with 65 (14.4%) controls, p < .001. Twenty-five (13.9%) exposed women experienced postpartum complications versus 26 (7.5%) in the control group (p = .019). Maternal ICU admission occurred in 13 (7.3%) of the exposed group as compared with only 2 (0.6%) in controls (p < .001). CONCLUSIONS: Women with a background cardiac condition, particularly those with severe disease, are at a higher risk for an unplanned cesarean delivery and other peripartum complications as compared with matched healthy controls.

BACKGROUND: A fetus exposed to maternal anti-SSA/Ro or anti-SSB/La antibodies (or both) may develop complete atrioventricular block (AVB), which results in high prenatal and postnatal morbidity and mortality. Until recently, only high-grade AVB could be diagnosed in utero. The tissue velocity-based fetal kinetocardiogram (FKCG) enables accurate measurement of AV conduction time and diagnosis of low-grade AVB. In the present multicenter observational study, we used FKCG to detect first-degree AVB in fetuses at risk. METHODS AND RESULTS: FKCG was performed in 70 fetuses of 56 mothers who were positive for anti-SSA/Ro and/or anti-SSB/La. Fetuses were monitored with weekly FKCG from 13 to 24 weeks' gestation, followed by monthly assessments until delivery in unaffected fetuses and weekly assessments in affected fetuses. AV conduction in 70 at-risk and 109 normal fetuses was compared. FKCG was obtained readily in all fetuses; 6 showed first-degree AVB (AV conduction time >2 z scores above normal mean) at 21 to 34 gestational weeks. Immediate maternal treatment with dexamethasone resulted in normalization of AV conduction in all affected fetuses within 3 to 14 days. AV conduction time in the remaining 64 untreated fetuses remained normal throughout gestation. The ECG PR interval immediately after birth was normal in all affected newborns. No child developed AVB or cardiomyopathy in the subsequent 1- to 6-year (median 4-year) follow-up. CONCLUSIONS: The present findings suggest that an FKCG can detect first-degree AVB in the fetus exposed to maternal anti-SSA/Ro or anti-SSB/La antibodies (or both). Dexamethasone given on detection was associated with normalized AV conduction in fetuses with first-degree AVB. No fetus in the present study developed complete prenatal or postnatal AVB.

AIMS: To determine the incidence of postpartum diabetes mellitus in the years following a diagnosis of gestational diabetes mellitus (GDM) and to determine whether the severity of GDM, represented by the magnitude of the deviation of diagnostic tests from the normal values or requirement for medications, is associated with the development of diabetes. METHODS: A retrospective cohort study was performed among 185 416 pregnant women who had glucose challenge test or 3 h oral glucose tolerance test (OGTT) in a large health maintenance organization in Israel. Subsequent diagnosis of diabetes was ascertained by using an automated patient registry. RESULTS: A total of 11 270 subjects were diagnosed with GDM, comprising 6.07% of the cohort. During a total follow-up period of 1 049 334 person-years there were 1067 (16.9 per 1000 person-years) and 1125 (1.1 per 1000 person-years) diagnoses of postpartum diabetes among GDM and non-GDM women, respectively. The cumulative risk of incident diabetes in GDM patients with up to 10 years of follow-up was 15.7%, compared with 1% among the non-GDM population. Gestational diabetes mellitus was associated with nearly an eightfold higher risk of postpartum diabetes after adjusting for important confounders, such as socioeconomic status and body mass index. Among women with a history of GDM, the number of abnormal OGTT values and use of insulin were associated with a substantially higher risk for developing diabetes. CONCLUSIONS: Three or four abnormal OGTT values and GDM requiring insulin or oral hypoglycaemic medications are important predictors of postpartum diabetes risk in women with a history of GDM.

BACKGROUND: Neuraxial analgesia significantly increases the success rate of external cephalic version (ECV) among nulliparae. The study objective was to compare ECV success among multiparae with and without spinal analgesia. METHODS: Prospective randomized controlled trial performed over a pre-defined 6 yr period in a tertiary referral delivery suite. Healthy multiparae at term requesting ECV for breech presentation, without fetal or uterine anomaly, were enrolled after written informed consent. Women were randomized to receive either spinal analgesia (bupivacaine 7.5 mg) or no analgesia before the ECV. The primary outcome was successful conversion from breech to vertex presentation, confirmed by ultrasound. Visual analogue pain score and adverse outcomes (complications of anaesthesia or ECV) were recorded. Statistical analysis was performed according to intention to treat using two-sided tests. RESULTS: Among 265 multiparae who underwent ECV, 65 consented to enrol, one subsequently refused ECV; therefore, data from 64 women were analysed. ECV was successful in 27 of 31 patients (87.1%) receiving spinal analgesia vs 19 of 33 (57.5%) with no analgesia (P=0.009; 95% CI of difference: 0.075-0.48). ECV with spinal analgesia reduced visual analogue pain score, mean (sd) 1.7 (2.4) vs 5.5 (2.9) without (P<0.0001). Maternal hypotension was seen after spinal analgesia in 10 of 31 (32%) (P=0.0003) and easily treated without adverse outcome. No complications were noted after the ECV. CONCLUSIONS: Administration of spinal analgesia significantly increased the rate of successful ECV among multiparae at term with increased patient comfort. The trial was registered at the National Institute of Health Trials Registry, NCT00119184, www.clinicaltrials.gov.

BACKGROUND: No therapy is currently available to improve the reduced uteroplacental blood flow (UPBF) that characterizes pre-eclampsia. We hypothesized that sympathectomy induced by epidural local anaesthesia reduces uterine vascular resistance (which is inversely correlated with UPBF) in pre-eclampsia. METHODS: Ten pregnant women between 24 and 32 weeks of gestation with pre-eclampsia and uterine artery flow abnormalities were randomized to antepartum continuous epidural therapy (ACET) or control. ACET was initiated by a 5 day dose-ranging trial (ACET-1) of 0.04, 0.06, 0.08, and 0.1% ropivacaine and saline placebo, each at 10 ml h(-1) for 24 h. Doses were randomized and double-blind. Doppler ultrasound indices of vascular resistance were assessed at baseline and after each 24 h dosing period in both uterine arteries. Subsequently, these ACET patients were administered 0.1% ropivacaine until delivery (ACET-2), with one additional randomized double-blind placebo day. RESULTS: Five patients were randomized to ACET. In each patient, one uterine artery exhibited a dose-dependent reduction in vascular resistance (P=0.035), a response that returned to baseline following placebo (P<0.001). The contralateral uterine artery exhibited either increased vascular resistance or no change. In all cases, the uterine artery that responded to ACET had higher baseline resistance than its pair (P=0.043). Baseline right-left difference in resistance between paired uterine arteries was greatly diminished following ACET. Although ACET patients had a mean (sd) duration to delivery of 19 (9) days compared with control 2 (1) days (P=0.008), this should be interpreted with caution because of demographic differences between groups. CONCLUSIONS: ACET reduces uterine artery resistance in pre-eclampsia <32 weeks. Uteroplacental re-distribution is a novel observation and warrants further investigation.

BACKGROUND: The post-void residual volume is higher among parturients who received epidural analgesia than those who received no or alternative analgesia. METHODS: This prospective, randomized, controlled, non-blinded study was performed in a tertiary referral center labor suite. The post-void residual volume was measured by a transabdominal ultrasound following a voiding attempt. Healthy parturients with low-dose epidural analgesia in active labor were randomized either to walk to the toilet or to use a bedpan for voiding. The primary outcome measure (post-void residual volume in labor) was compared between the study groups. RESULTS: The toilet group (n=34) and the bedpan group (n=28) demonstrated similar post-void residual volumes (212 +/- 100 vs. 168 +/- 93 ml, P=0.289). Twenty patients (59%) randomized to the toilet group were unable to walk and actually voided in a bedpan. A secondary analysis was performed analyzing the groups as treated. The post-void residual volume was significantly lower in the actual toilet group (n=14, 63 +/- 24 ml) vs. the bedpan group (n=48, 229 +/- 200 ml), P=0.0052. Thirteen (93%) women who walked to the toilet managed to void before the ultrasound measurement vs. 20/48 (42%) using the bedpan, P=0.001. Fewer women who managed to walk to the toilet required urinary bladder catheterization during the labor than women who used the bedpan (6/14, 43% vs. 36/48, 75%) P=0.028. CONCLUSION: Women who were randomized to walk to the bathroom with epidural analgesia and were able to do so during labor had a significantly reduced post-void residual volume and a reduced requirement for urinary catheterization.

A parturient (grand multipara) developed arrested labour complicated by severe fetal heart rate decelerations. Senior physicians explained the need for a caesarean section, but she chose to deliver vaginally since rabbinical blessing could not be obtained. Forcing the mother to have a cesarean section without consent is considered "civil battery." The dilemma faced by medical staff and the implications of her refusal for the treating medical staff are described.

Using oligonucleotide microarrays we recently identified a set of transcripts that were up-regulated in hypoxic human trophoblasts. To test the hypothesis that expression of hypoxia-related placental transcripts depends on sampling site we analyzed nine different sites from term human placentas (n=6), obtained after uncomplicated pregnancies. These sites spanned the placental center to the lateral border and the basal to the chorionic plate. Relative gene expression at each site, determined using quantitative PCR, was correlated with villous histology. The expression of vascular endothelial growth factor (VEGF) and connective tissue growth factor (CTGF), the cytoskeleton proteins lamininA3 and alpha-tubulin, and the signal transduction protein Rad was enhanced in the subchorionic lateral border compared to medial basal site (1.6-2.9 fold, p<0.05). In contrast, the expression of NDRG1, adipophilin and human placental lactogen was unchanged. Enhanced villous maturation, syncytial knots and fibrin deposits were more frequent in the subchorionic placental lateral border, and correlated with up-regulation of hypoxia-related transcripts (p<0.05). The association between sample site and expression level was not observed in placentas with marginal cord insertion. The expression of hypoxia-related genes in the term human placenta is dependent on sampling site within the placental disk, likely reflecting local differences in villous perfusion.

Earlier studies noted that patients who underwent cord blood (CB) transplantation had a lower incidence of graft-versus-host disease (GVHD) than those who underwent bone marrow transplantation (BMT). The premise that the immune reactivity of CB mononuclear cells (CB-MNC) to HLA mismatched combinations and to noninherited maternal antigens (NIMA) may be one of the factors involved in this phenomenon is still debatable. In this study we have attempted to evaluate the alloresponse and alloreactivity induced by CB-MNC by means of the standard mixed lymphocyte reaction test (SMLR) and the more sensitive, modified mixed lymphocyte reaction test (MMLR). Both techniques were used to test CB-MNC (n = 28) against HLA class II mismatched MNC from mothers (n = 26), fathers (n = 12), and unrelated individuals (n = 60) who served as controls. Alloresponse capabilities and stimulation capacities of CB-MNC in the SMLR were similar to those of control MNC: relative response (RR) = 73 vs. 65 and 58 vs. 65, respectively. Similar results were obtained in the MMLR. CB-MNC responded weakly to the maternal MNC in comparison with control MNC (RR = 47 vs. 73 [p = 0.0099]), while a stronger response was noted to the paternal than the maternal MNC (RR = 72 vs. 47 [p = 0.045]). Our results demonstrate that CB-MNC both respond to and induce alloresponse in HLA mismatched combinations. Moreover, the hyporesponse of CB-MNC to maternal cells that we observed suggests a form of tolerance to NIMA, which is probably due to the fetus's exposure to these antigens in its intrauterine life.

The aim of this study was to determine placental thickness by ultrasound examination throughout pregnancy and establish the correlation of sonographically thick placenta with perinatal mortality and morbidity. Placental thickness was determined by routine sonographic examination throughout pregnancy in 561 normal singleton pregnancies. Thick placenta was determined as placenta that was above the 90th percentile. Gravidae between 20-22 weeks' gestation (n=193) and 32-34 weeks (n=73) were then divided into two groups according to placental thickness. The study group consisted of 44 gravidae with thick placenta. The control group included 151 gravidae with placental thickness between the 10th and 90th percentile. A comparison of perinatal mortality and morbidity rates as well as the incidence of small and large for gestational age neonates was conducted.A linear increase of placental thickness was found to correlate with gestational age throughout pregnancy. No statistical differences were observed between the two groups with regard to obstetrical variables such as maternal age, parity and gestational age at delivery. No correlation was found between placental thickness and maternal age or parity. The incidence of perinatal mortality was significantly higher among gravidae with thick placentae (6.82% versus 0.66 per cent, P=0.037, 95 per cent confidence interval 1.71-70.29). Birthweight at term was found to be above 4000 g in 20.45 per cent of the thick-placenta group as compared to 5.3 per cent in the control group (P=0.001, 95 per cent CI 2.08-13.85), and birthweight of less than 2500 g was found in 15. 9 per cent of the thick-placenta group as compared to 7.3 per cent in the control group (P=0.03, 95 per cent CI 1.11-8.14). The incidence of fetal anomalies was 9.1 per cent in the thick-placenta group and 3.97 per cent in the control group (not significant). Sonographically thick placenta is associated with increased perinatal risk with increased mortality related to fetal anomalies and higher rates of both small for gestational age and large for gestational age infants at term.

Human umbilical cord blood (HUCB) represents a unique source of transplantable hematopoietic progenitor cells. HUCB from a newborn sibling has been used successfully for hematopoietic reconstitution of more than 50 children with congenital and malignant diseases. Moreover, 13 HUCB transplants have been performed from unrelated donors. Bone marrow transplantation (BMT) has rapidly progressed over the last two decades offering cure and prolonged disease free survival in patients with hemato-oncological malignancies, metabolic and genetic disorders. BMT is limited by the paucity of HLA-matched donors and the morbidity and mortality due to graft-versus-host disease (GVHD). HUCB could alleviate some of the problems associated with BMT and establishment of HUCB bank and registries could become an easily available source of suitable stem cells for transplantation. This review focuses on identifying current scientific problems and clinical achievement as well as noting the most recent developments in the field with special attention to the collection, processing, cryopreservation, and banking of HUCB. Progenitor cells from cord blood may provide an excellent vehicle for future gene therapy. As a result of relative immunodeficiency at birth, it is likely that partially matched unrelated cord blood transplants (CBT) would be successful due to a lower risk of GVHD related problems. Therefore, the establishment of large cord blood banks is of the utmost importance, in the future.

OBJECTIVE: To assess the outcome of pregnancies conceived with the use of IVF that are complicated by severe ovarian hyperstimulation syndrome (OHSS). DESIGN: A retrospective nationwide multicenter study. SETTING: Sixteen of 19 tertiary care medical centers in Israel. PATIENT(S): All patients undergoing IVF who were hospitalized for severe OHSS between January 1987 and December 1996. MAIN OUTCOME MEASURE(S): Pregnancy rate (PR) and rates of multiple gestation, miscarriage, ectopic pregnancy, obstetric complications, and intervention. RESULT(S): A total of 163 patients who had severe OHSS after IVF treatment were identified, of whom 142 (87.1%) had undergone ET. The clinical PR was 73.2%; 42.3% were singletons, 33.6% were twins, 17.3% were triplets, and 6.7% were quadruplets. The miscarriage rate was 29.8%, whereas the incidence of ectopic pregnancy was 1.9%. Forty-four percent of all births were premature, and 62.1% of all newborns had low birth weight. The most common antenatal complications were pregnancy-induced hypertension (13.2%), gestational diabetes (5.9%), and placental abruption (4.4%). The rate of cesarean section was 44.1%. CONCLUSION(S): Among patients who have severe OHSS after IVF treatment, the pregnancy rate and the rates of multiple gestation, miscarriage, prematurity, low birth weight, pregnancy-induced hypertension, gestational diabetes, and placental abruption are significantly higher than those reported previously for pregnancies conceived with the use of assisted reproductive techniques.

OBJECTIVE: To assess the pulmonary manifestations of severe ovarian hyperstimulation syndrome (OHSS). DESIGN: A retrospective nationwide 10-year multicenter study. SETTING: Sixteen of 19 tertiary medical centers in Israel. PATIENT(S): All patients hospitalized at these centers for severe OHSS between January 1987 and December 1996. MAIN OUTCOME MEASURE(S): Clinical presentation, arterial blood gases on room air, and chest roentgenogram results. RESULT(S): Of 209 patients, 4% had lobar pneumonia, 2% had adult respiratory distress syndrome (ARDS), and 2% had pulmonary thromboembolism. Most patients had dyspnea, tachypnea, moderate hypoxemia, increased alveolar-arterial oxygen difference, hypocarbia, respiratory alkalosis, and metabolic compensation. The most common findings on chest roentgenogram were bilateral elevation of the diaphragm, pleural effusion, and pulmonary atelectasis. Patients with pulmonary thromboembolism, ARDS, and pneumonia presented with severe hypoxemia and alveolar-arterial oxygen difference and distinct radiographic findings. CONCLUSION(S): Severe OHSS is characterized by an extraparenchymal restrictive type of pulmonary dysfunction, attributed to intraabdominal or pleural fluid accumulation, which limits descent of the diaphragm and expansion of the thoracic cage. This may induce uncoordinated lung ventilation and atelectasis with subsequent ventilation-perfusion mismatch and hypoxemia. The clinical picture may deteriorate further because of pulmonary infection, pulmonary thromboembolism, or ARDS, all of which have distinct clinical, radiographic, and blood gas characteristics.

OBJECTIVE: To assess immunoglobulin (Ig) concentrations in plasma and ascitic fluid of patients with severe ovarian hyperstimulation syndrome (OHSS). DESIGN: Controlled clinical study. SETTING: Tertiary medical center. PATIENT(S): Ten patients with severe OHSS after ovulation induction for IVF and 10 controls who had undergone similar ovulation induction and did not develop OHSS. INTERVENTION(S): Three blood samples were obtained from each OHSS patient: one at the time of hospitalization for severe OHSS, one when significant clinical improvement was evident, and one at the first follow-up visit after discharge from the hospital. Blood samples were drawn from control patients 6-8 days after ET. Ascitic fluid was obtained from all patients with OHSS by therapeutic paracentesis. MAIN OUTCOME MEASURE(S): Immunoglobulin concentrations were assayed by radial immunodiffusion. RESULT(S): Significantly lower levels of gamma-globulins, specifically IgG and IgA, were detected in the plasma of patients with severe OHSS, whereas alpha- and beta-globulin levels as well as IgM levels were not significantly different from those in controls. Both IgG and IgA levels increased as patients clinically improved. Ascitic fluid contained high IgG, moderate IgA, and negligible IgM levels. CONCLUSION: Severe OHSS is characterized by hypogammaglobulinemia, attributed to leakage of medium-molecular-weight immunoglobulins such as IgG and IgA to the peritoneal cavity.

OBJECTIVE: To determine whether women with epithelial ovarian cancer are more likely to have been exposed to fertility drugs, and in particular hMG, than healthy population controls. DESIGN: A nationwide case-control study. PATIENTS: Two hundred living women 36 to 64 years of age, with a histologically confirmed diagnosis of primary invasive or borderline epithelial ovarian cancer that was first diagnosed and reported to the Israel Cancer Registry between January 1, 1990 and September 1, 1993 were enrolled. There were 164 (82%) invasive and 36 (18%) borderline epithelial ovarian tumors among the 200 cases. The controls were 408 women from the same dialing areas selected by random digit dialing. Cases and controls were interviewed using a standard questionnaire. A multivariate logistic model was used to assess the association of fertility drug use and ovarian cancer, controlling for variables found to be statistically associated with this outcome on univariate analysis. RESULTS: Twenty-four women with epithelial ovarian cancer (12%) and 29 healthy controls (7.1%) reported that they had used any fertility drug (adjusted odds ratio [OR] 1.31; 95% confidence interval [CI] 0.63 to 2.74). Among cases and controls, respectively, 22 and 24 reported that they had used hMG alone or in combination with clomiphene citrate (adjusted OR 1.42, 95% CI 0.65 to 3.12), and 11 and 6 reported that they had used hMG alone (adjusted OR 3.19, (95% CI 0.86 to 11.82). The risk was increased particularly in the subgroup of women with borderline ovarian tumors who had used hMG (adjusted OR 9.38, 95% CI 1.66 to 52.08). CONCLUSIONS: We conclude that the use of ovulation induction agents, in particular hMG, may increase the risk of epithelial ovarian tumors.

The new hysteroscopic approach toward pregnancy loss associated with uterine septum offers several advantages over abdominal metroplasty. However, several safeguards should be taken: laparoscopic or sonographic guidance should accompany hysteroscopic metroplasty; postoperative HSG or hysteroscopy is recommended; there is no advantage of IUD insertion postoperatively; sequential estrogen-progesterone therapy postoperatively is optional, but of no proved benefit; a hysteroscopic approach toward uterine septum is the preferred procedure, even when laparotomy for treatment of pelvic endometriosis or intrapelvic adhesions is indicated, and, although its value is not established, a short perioperative cause of prophylactic antibiotics seems to be warranted.

Cervical pregnancy (CP) is a rare life-threatening form of ectopic pregnancy occurring in 1 of 8628 deliveries. We reviewed 117 cases of CP in the English language literature from 1978 and added three cases from our department. Etiology of CP is still unknown, but there is evidence for its association with cervicouterine instrumentation. The possible role of embryo chromosomal abnormality in the CP etiology is considered. Sonography improved pretreatment diagnosis up to 81.8 percent. Obligatory sonographic criteria of CP include endocervical localization of the gestational sac and trophoblastic invasion. About 60 percent of cervical pregnancies are with a viable fetus. The majority of patients with a cervical pregnancy are women with low parity, thus, the current treatment trend is to preserve their reproductive function. The main problem of conservative treatment is life-threatening hemorrhage after pregnancy evacuation. The use of cervical canal tamponade with a Foley catheter balloon led to reliable hemostasis in 92.3 percent of cases in which this method was used. Early diagnosis of CP allowed for treatment by chemotherapy in 32 cases, with an 81.3 percent success rate. Serial beta-human chorionic gonadotropin levels and transvaginal ultrasound with color Doppler are used to monitor therapy. Another conservative treatment modality is local intrasac KCI injections. Hysterectomy is recommended mostly for second and third trimester cervical pregnancy, or for uncontrolled bleeding.

Bone marrow transplantation has rapidly progressed over the last two decades offering cure and prolonged disease-free survival for patients suffering from certain hemato-oncological malignancies or metabolic disorders. However, bone marrow transplantation is limited by the paucity of major histocompatibility loci antigen (HLA)-matched donors, and the morbidity and mortality due to graft-versus-host disease. Recently it has been shown, that umbilical cord blood represents a unique source of transplantable hematopoietic progenitor cells. Currently, human umbilical cord blood from a newborn sibling has been used successfully for hematopoietic reconstitution of approximately 40 children with congenital or malignant diseases. Establishment of umbilical cord blood banks might alleviate some of the problems associated with bone marrow transplantation. The developments in this field which have occurred during the last decade, as well as the importance of cooperation between the obstetric and transplantation staff, are discussed in this review. Certain ethical problems remain surrounding the issue of using human umbilical cord blood for allogeneic transplantation which must be addressed.

Ritualistic sexual mutilation of females dates back to the fifth century B.C. This traditional practice is a social as well as a health issue that affects the physical and mental well being of the women who undergo it. Although practiced mostly in African countries north of the equator and the Middle-East, concern has recently been expressed that female genital mutilation is also being practiced in the U.S., Europe, and other western countries by immigrants from these countries. This review describes the various types of female genital mutilation and presents the historical and cultural background of the tradition, outlines the medical, psychological and sexual problems, and discusses the current status and future outlook for this tradition, emphasizing social, medical, and legislative aspects.
