Risk factors for rape re-victimisation: a retrospective analysis.

Sexual re-victimisation refers to a pattern in which the sexual assault victim has an increased risk of subsequent victimisation relative to an individual who was never victimised. The purpose of our study was to identify risks factors for a second rape, the severest form of sexual re-victimisation. All rape victims treated at the First Regional Israeli Center for Sexual Assault Victims between October 2000 and July 2010 were included in this retrospective analysis. We compared characteristics of 53 rape victims who were victimised twice to those of 1,939 rape victims who were victimised once. We identified several risk factors for a second rape, which can be used in prevention programmes. These are: psychiatric background, history of social services involvement, adulthood, non-virginity and minority ethnicity.

The placental factor in early- and late-onset normotensive fetal growth restriction.

OBJECTIVE: Our objective was to investigate the placental component in early- and late-onset fetal growth restriction (FGR) compared to placentas from neonates appropriate for gestational age (AGA). STUDY DESIGN: Placentas from normotensive women who gave birth at 24-42 weeks to neonates with a birth-weight below the 10th percentile (FGR group), or to healthy AGA neonates (AGA group), were analyzed. Placental lesions were classified to lesions related to maternal underperfusion, lesions consistent with fetal thrombo-occlusive disease and inflammatory lesions. Findings were compared between patients who delivered ≤ 34 weeks (early-onset FGR) or >34 weeks (late-onset FGR) and controls with AGA neonates. RESULTS: The early-onset FGR group (n = 24) had a higher rate of placental vascular lesions related to maternal underperfusion than the late-FGR group (n = 334) (41.7% vs. 8.7%, P < 0.001) and more villous lesions related to maternal underperfusion than the preterm AGA group (n = 68) (70.8% vs. 5.9%, P < 0.001). The late-onset FGR group had more placental villous lesions related to maternal underperfusion (57% vs. 19% P < 0.001) and more lesions consistent with fetal thrombo-occlusive disease (26.3% vs. 8.5%, P < 0.001) than the term AGA group (n = 153). CONCLUSION: Early- and late-onset FGR have different placental pathology compared with AGA controls, suggesting that a combination of fetal and maternal vascular compromise is more dominant in the late-onset FGR, rather than more severe maternal vascular compromise in early-onset FGR.

The effect of coexisting uterine myomas on clinico-pathological variables of endometrial carcinoma.

PURPOSE: To assess the prevalence of leiomyomas in patients with endometrial carcinoma (EC) and the association of their presence with clinico-pathological variables and with survival. MATERIALS AND METHODS: A retrospective chart review was conducted of all endometrial carcinoma (EC) patients diagnosed and treated in the present institution between 2002 and 2008. Selected clinical data were abstracted from medical records. Pathological data such as the presence of myomas (any size), tumor grade, depth of myometrial invasion presence of lymphovascular space involvement (LVSI), and the presence of metastases, are based on the original pathology report. RESULTS: Coexisting myomas were found in 74 (56.9%) of 130 EC patients diagnosed during the study period. No significant difference with regard to age, histological type, stage, grade, depth of myometrial invasion, LVSI, lymph node involvement, and presence of metastases (other than lymph node involvement) was found between patients without and with myomas. There was also no significant difference in survival of EC patients without and with coexistent myomas. CONCLUSION: The present data seem to indicate that the presence of myomas does not affect clinico-pathological variables of EC patients nor their survival.

Postoperative analgesia with tramadol and indomethacin for diagnostic curettage and early termination of pregnancy.

BACKGROUND: The postoperative analgesic effects of rectal indomethacin and tramadol were compared in patients undergoing elective termination of first trimester pregnancy and diagnostic dilatation and curettage. METHODS: Eighty-one American Society of Anesthesiologists class I and II women undergoing first trimester termination of pregnancy or diagnostic dilation and curettage were randomly allocated to receive rectal suppositories of either tramadol 100 mg (n=41) or indomethacin 100 mg (n=40) 90 min before induction of anesthesia. Pain scores and side effects were evaluated until discharge. Intraoperative anesthetic and postoperative analgesic consumption was also recorded. Intravenous metamizole 1 g was employed for postoperative rescue analgesia. RESULTS: When compared to the indomethacin group, the tramadol group required less intraoperative propofol [136 mg ±28 vs. 160 mg ±35 (P=0.001)], less rescue analgesia [2.4% vs. 22% (P=0.005)] and lower visual analogue pain scores [2.4 ±8 vs. 23 ±22 (P=0.005)]. The incidence of postoperative nausea and vomiting was similar in both groups. CONCLUSION: When compared to indomethacin 100 mg, preoperative administration of tramadol 100 mg provides superior postoperative analgesia with minimal adverse effects.

Association of non-reassuring fetal heart rate and fetal acidosis with placental histopathology.

OBJECTIVE: To investigate the association between different placental lesions and non-reassuring fetal heart rate (NRFHR) pattern and fetal acidosis in labor. STUDY DESIGN: Placentas from 213 women who underwent cesarean section because of NRFHR with or without fetal acidosis (pH < 7.2) were classified by histopathologic findings: consistent with maternal circulation abnormalities i.e., namely, marginal or retroplacental hemorrhage (M0), maternal underperfusion, vascular (M1) or villous changes (M2), and those consistent with fetal thrombo-occlusive disease due to vascular (F1) or villous (F2) changes. Lesions were also analyzed by maternal (MIR) or fetal (FIR) origin of inflammatory responses. RESULTS: Cord blood pH was normal in 169 neonates (7.29 ± 0.04; control group) and <7.2 in 44 (7.10 ± 0.07; study group). The study group had higher rates of histologic chorioamnionitis; MIR was detected in 34.1% compared to17.8% of controls (p = 0.018), and FIR, in 18.2% compared to 6.5% (p = 0.016). Neonates in the study group had lower Apgar scores and longer hospitalization. CONCLUSIONS: Placental MIR and FIR are associated with cord blood acidosis in neonates delivered by cesarean section for NRFHR tracings in labor.

Placenta-bound and body fluid PP13 and its mRNA in normal pregnancy compared to preeclampsia, HELLP and preterm delivery.

OBJECTIVES: To compare the distribution of placental protein 13 (PP13) in fetal and maternal blood and amnionic fluid and to correlate it with PP13 protein and mRNA in the placenta. METHODS: Umbilical arterial serum, amnionic fluid, maternal venous serum and placental tissues were collected from normal outcome pregnancies (N = 63) (GA>37), early onset preeclampsia (PE) (N = 12, GA: 26-33), and HELLP syndrome (N = 5, GA: 27-29). Because PE and HELLP cases delivered preterm, cases of preterm delivery (PTD) (N = 6, GA: 31-36) served as additional control. PP13 was determined by ELISA, Western blot, and immunohistochemistry. PP13 mRNA was measured by PCR (RT-PCR). Continuous parameters were compared by t-test, P < 0.05 was considered significant. RESULTS: In women with normal pregnancy outcome significantly higher PP13 levels were found in maternal serum compared to amnionic fluid and negligible amount was found in fetal serum. A similar pattern was identified in cases of PTD with concentrations similar to term control. In PE and HELLP cases PP13 levels in amnionic fluid level were more than twice compared to maternal serum (P < 0.001). Umbilical cord level was negligible in PE but high in HELLP corresponding to the much higher level of PP13 in this patient group compared to all others. In the placenta PP13 level in term controls was higher compared to PTD. In PE and HELLP (similar early delivery time as PTD) the level was significantly higher (P < 0.01) compared to PTD or term controls. PP13 mRNA levels in term control and PTD were similar while PP13 mRNA levels in PE and HELLP placentas were significantly lower compared to term controls or PTD or the two combined. Syncytiotrophoblast labeling appeared stronger in PE and HELLP compared to term controls and PTD. CONCLUSIONS: In all cases but HELLP, PP13 in fetal blood is very low indicating that routing of PP13 to fetal blood is limited and that the fetus is unlikely to generate PP13. PP13 mRNA is lower in the third trimester at the time of disease while protein level accumulates and become higher creating an unparallel change in the level of the mRNA and the corresponding protein.

Effect of vaginal progesterone, administered to prevent preterm birth, on impedance to blood flow in fetal and uterine circulation.

OBJECTIVE: To evaluate the effect on the maternal and fetal circulation of progesterone administered to prevent preterm birth. METHODS: We used an observational cohort study design. The study group included 44 women at 18-32 weeks' gestation who presented with an episode of preterm labor, with or without history of delivery before 34 weeks' gestation, or an incidental finding of short cervix (≤ 25 mm). Doppler flow assessment of the umbilical artery, fetal middle cerebral artery and uterine arteries was performed before and 24 h after vaginal administration of progesterone. RESULTS: Seventeen (38.6%) women gave birth before term, but only nine (20.4%) did so before 34 weeks' gestation. Following progesterone treatment, there was a statistically significant decrease in the pulsatility index of the fetal middle cerebral artery (mean reduction, 18.2%; mean change in pulsatility index, 0.44 (95% CI, 0.25-0.63), P < 0.001), with no changes in the other vessels. Comparison of the women who gave birth before with those who delivered at term yielded no significant differences in Doppler flow parameters in any vessel examined, either before or after progesterone treatment. CONCLUSION: Treatment with vaginal progesterone is associated with a lower pulsatility index in the fetal middle cerebral artery, suggesting a vasodilatory effect on the fetal circulation.

Fasting does not precipitate onset of labour.

This retrospective observational study examined whether fasting (the 'Yom Kippur effect') precipitates labour. Birth rates of Yom Kippur (a fasting festival) were compared with those of other festivals that are observed (Tisha B'Av) and not observed (1st day of Passover) by fasting during a 4-year period. Compared with the mean birth rate, the number of births that occurred 1 day after Yom Kippur was increased (p = 0.023). A significant decrease in the number of births during Tisha B'Av (p = 0.044) and a significant increase in the number of births 2 days after Tisha B'Av (p = 0.009) was observed. Two days prior to the 1st day of Passover, a significant decrease in the number of births was also observed (p = 0.034). Contrary to previous reports, the present study does not confirm an association between a 1-day long fast and increased birth rate in the 24-h period after breaking of the fast.

Combining flow cytometry and gfp reporter gene for quantitative evaluation of Pectpbacterium carotovorum ssp. carotovorum in Ornithogalum dubium plantlets.

AIMS: Ornithogalum dubium is a natural host of the soft rot pathogen Pectobacterium carotovorum ssp. carotovorum (Pcc). The present study was aimed to develop a quantification system for Pcc expressing a gfp reporter gene, using fluorescent activated cell sorter (FACS) in planta. METHODS AND RESULTS: Several calibration steps were required to distinctly gate the GFP-labelled bacteria at FL1 mode and count the bacteria. To validate the bacterial counts obtained by FACS analysis, an internal standard of polystyrene green fluorescent microsphere beads was employed, resulting in high correlation with serial dilutions and plate counting. This allowed quantification of the bacteria, with no further need to culture, dilute or plate the cells. Micropropagation tools were developed to produce uniform plantlets of O. dubium, which were either inoculated with increasing concentrations of Pcc or elicited for resistance towards Pcc using methyl jasmonate. The rapid counting procedure allowed recovering, gating and counting the bacterial population in planta, separately from the plant cells background and from the microsphere beads. CONCLUSIONS: The FACS based quantification approach of Pcc was found accurate, reproducible and time saving, thus useful for counting bacteria in planta. SIGNIFICANCE AND IMPACT OF THE STUDY: The combination of time- and cost-saving approach for Pcc quantification with efficient screening tools during early stages of micropropagation may facilitate the preliminary process of selection for resistant cultivars.

Cox-2 immunohistochemical expression in epithelial ovarian carcinoma and platin sensitivity.

PURPOSE: The aim of the study was to assess whether COX-2 expression in epithelial ovarian carcinoma (EOC) tissue can distinguish between platin-sensitive and platin-resistant tumors. METHODS: Clinical and histological data were obtained from medical records of EOC patients diagnosed between the years 1995 and 2005. Patients in complete clinical remission for > 6 months after discontinuation of first-line chemotherapy were considered to be platin-sensitive. Survival of < or = 2 and > 5 years after diagnosis was considered as short- and long-term survival, respectively. Immunohistochemistry staining was performed on deparaffinized sections of tissue blocks obtained at first surgery. The intensity of staining and the percentage of stained cells was assessed by two pathologists blinded to clinical data and a scoring index was calculated. RESULTS: Among 79 patients a positive stain (> 10% of cells stained) was observed in 61 (77.2%). No statistically significant association between distribution of platin sensitivity and immunohistochemical COX-2 staining parameters was observed, although the rate of long-term survival was significantly higher among platin-sensitive then among platin-resistant/unresponsive patients. CONCLUSIONS: Immunohistochemically determined COX-2 expression in EOC is not associated with platin sensitivity and survival.

Platin sensitivity and long-term survival in Stage III epithelial ovarian cancer patients.

PURPOSE: The aim of the present study was to assess the effect of platin sensitivity on long-term survival of Stage III epithelial ovarian cancer (EOC) patients. METHODS: The records of all histologically confirmed Stage III EOC and PPC patients diagnosed during 1995-2006 were reviewed. A comparison of selected characteristics was made between long-term (> 5 years) and short-term (< 3 years) survivors. RESULTS: Among 58 Stage III patients, 20 had long-term and 18 short-term survival. The rate of platin sensitive patients in long-term survivors was significantly higher than in short-term survivors (95.0% vs 27.8%, p < 0.001). The sensitivity and specificity of platin sensitivity for long-term survival was 95% and 72.2%, respectively, and the positive and negative predictive value was 79.2% and 92.8%, respectively. No statistically significant difference between the groups was found with regard to other selected characteristics. CONCLUSION: The rate of platin sensitive patients was significantly higher among long-term survivors than among short-term survivors but the specificity and positive predictive value of platin sensitivity for long-term survival prediction were relatively low precluding its practical clinical use.

Magnetic acupressure for management of postoperative nausea and vomiting: a preliminary study.

BACKGROUND: To assess the efficacy of magnetic acupressure in the prevention of postoperative nausea and vomiting (PONV). METHODS: Fifty-eight patients were included in this randomized, double blind, preliminary prospective study. Thirty-three underwent ear, nose, and throat (ENT) procedures and twenty-five underwent gynaecological procedures. A magnet patch (M) or a placebo patch (P) was applied to patients in each group randomly. The patch was applied 15 min before surgery to P6 a point situated above the wrist, on the medial aspect of the arm between the palmaris longus and flexor carpi radicis (REF point). Anaesthesia was standardized for all patients. Primary study endpoints included PONV scores and number of rescue antiemetic administrations. Secondary endpoints included pain scores, percentage of patients who required rescue analgesics and satisfaction scores. Study variables were measured on arrival in the PACU and 8, 16 and 24 h after surgery. RESULTS: The global incidence of PONV was 50%. We found no significant difference in the incidence of PONV between ENT patients (46%) and gynaecology patients (56%), and no difference between patients who received magnet treatment (47%) and those that did not (54%). Patients receiving the magnet had a similar satisfaction level (75% satisfied) to those receiving placebo (73% satisfied). In addition, magnet-treated patients had similar pain and PONV scores, and a similar percentage of patients in each groups received postoperative rescue analgesics. Finally, there was no difference in the number of rescue antiemetic administrations between the two groups. CONCLUSION: The use of magnetic acupressure as a prophylactic antiemetic treatment prior to ENT or gynaecology surgeries produced no benefit when compared to placebo.

Sonographic characteristics of the uterine cavity following first-trimester uterine evacuation.

OBJECTIVE: To characterize the sonographic appearance of the uterine cavity after first-trimester uterine evacuation and to follow the evolution of these findings in an attempt to reduce the number of unnecessary surgical interventions following evacuation. METHODS: We studied retrospectively the sonographic characteristics of the uterine cavity in 599 women, 5-8 days after first-trimester uterine evacuation. The patients were grouped according to the sonographic appearance of the uterine cavity. Patients with abnormal sonographic patterns were followed weekly until sonographic resolution. RESULTS: Group 1 included 351 (58.6%) women with normal endometrium; Group 2 included 130 (21.7%) women with hypoechoic endometrial content only; Group 3 included 69 (11.5%) patients with mixed type (hypoechoic and hyperechoic) endometrial content; Group 4 included 49 (8.2%) patients with hyperechoic endometrial content only. The time needed until the uterine cavity was considered normal was significantly longer in Group 4 (median, 12 days) compared with Groups 3 and 2 (8 and 9 days, respectively, P < 0.0001). The duration of vaginal bleeding after the surgical procedure was longer in Group 4 (median, 10 days) compared with Groups 3, 2 and 1 (9, 7 and 5 days, respectively, P < 0.0001). Clinically, the patients were divided into two groups: asymptomatic (575 patients) and symptomatic (24 patients). The thickness of the abnormal endometrial content in the asymptomatic patients gradually decreased until normalization, around the time of menstruation. There was no such change in the symptomatic patients, who eventually needed surgical intervention. CONCLUSIONS: An abnormal intrauterine sonographic pattern 5-8 days following first-trimester uterine evacuation is common and usually resolves spontaneously around menses. Therefore, in asymptomatic patients, we recommend a conservative approach.

Favorable outcome following emergency second trimester cerclage.

BACKGROUND: To evaluate the outcome of midtrimester emergency cerclage with or without bulging of membranes. METHODS: A retrospective cohort study of 99 women who underwent emergency second trimester cerclage (16-27 gestational weeks). In 75 women the cervix was dilated and effaced but without bulging of membranes (group 1), and in 24 women the dilation and effacement of the cervix were accompanied by bulging of membranes into the vagina in an hourglass formation (group 2). McDonald technique was applied in all patients. RESULTS: Prolongation of pregnancy was significantly longer in group 1 compared to group 2 (14.3+/-6.5 vs 9.3+/-4.8 weeks, p=0.007). The mean gestational age at delivery was significantly higher in group 1 compared to group 2 (34.6+/-4.6 vs 29.5+/-3.2 weeks, p=0.001). The incidence of chorioamnionitis was higher in group 2 compared to group 1 but statistically insignificant (25% vs 15%, p=0.2). The overall neonatal survival was 83% (82 out of 99 neonates), without statistical difference between the two groups (86% in group 1 and 71% in group 2, p=0.2). CONCLUSIONS: Favorable neonatal outcome may be accomplished in patients with cervical incompetence in the second trimester of pregnancy following cervical emergency suturing even performed when the membranes are bulging through the cervix into the vagina.

Intra-uterine fluid collection in postmenopuasal women with cervical stenosis.

OBJECTIVES: The aim of the study was to assess the clinical significance of intra-uterine fluid collection in postmenopausal women with cervical stenosis with and without vaginal bleeding. METHODS: A group of 82 consecutive postmenopausal women with cervical stenosis and sonographically confirmed intra-uterine fluid collection underwent D&C with or without hysteroscopy. Diagnostic hysteroscopy was performed in all patients with an endometrial thickness (ET) was greater than 8mm, or with irregular endometrium at any degree of ET. The patients were divided and evaluated prospectively into two groups according to the presence or absence of postmenopausal bleeding (PMB). Twenty-six women were with PMB and 56 women were asymptomatic. RESULTS: The groups were similar as far as endometrial thickness and histopathological results were concerned. Atrophic endometrium was found in 69 patients (84%), 23 in the PMB group (89%) and 46 in the other group (82%), proliferative endometrium in 7 (9%) and endometrial polyps were found in 35 patients (43%), 12 in the PMB group (46%) and 23 in the other group (41%). When ET was > or =8 mm, in 93% of the cases an endometrial polyp was found (25 out of 27). No case of endometrial cancer was found. A premalignant condition was diagnosed in one patient with an endometrial polyp in the PMB group. All patients with endometrial thickness of less than 3 mm in ultrasound had atrophic endometrium. The incidence of intrauterine pathology increased with the increasing thickness of endometrium as observed by ultrasound. CONCLUSIONS: The presence of intra-uterine fluid collection in postmenopausal patients with cervical stenosis seems to be a benign condition. Normal endometrium of less than 3mm observed by ultrasound in postmenopausal women without vaginal bleeding does not necessarily need further surgical investigation.

Transvaginal ultrasound after first-trimester uterine evacuation reduces the incidence of retained products of conception.

OBJECTIVE: To assess the incidence of retained products of conception (RPOC) in relation to transvaginal ultrasound performed after first-trimester uterine evacuation. METHODS: This was a prospective randomized study involving 809 women undergoing first-trimester uterine evacuation. The study group included 404 women in whom transvaginal sonography was performed at the end of the surgical procedure and the control group contained 405 women who did not undergo ultrasound examination. Initially, in the study group, recurettage was immediately performed if the endometrium appeared irregular but latterly only if endometrial thickness was > or = 8 mm. The patients were followed up by gynecological and ultrasound examinations 5-8 days following the surgical procedure. RESULTS: The total complication rate was 4.3%. RPOC presented in three women in the study group (0.7%) and in 15 women in the control group (3.7%, P < 0.05). Vaginal bleeding requiring hospitalization occurred in two women in the study group (0.5%) vs. seven in the control group (1.7%, P = 0.2). Endometritis was diagnosed in one woman in the study group (0.2%) vs. six in the control group (1.5%) and uterine perforation occurred in one woman in the control group vs. none in the study group. There were no cases of RPOC in women who had an endometrial thickness of < 8 mm as demonstrated by ultrasound at the end of the surgical procedure. CONCLUSION: Transvaginal sonography immediately following first-trimester uterine evacuation may reduce the incidence of RPOC and the total complication rate. When the endometrial thickness is > or = 8 mm at the end of suction curettage, an attempt at re-evacuation of the uterine cavity is indicated.

Reproductive performance following midtrimester termination of pregnancy.

The aim of the study was to determine the impact of midtrimester abortion with extra-amniotic PGE(2) on future fertility and reproduction. Two hundred and fifteen women were enrolled. The mean induction-to-abortion interval was 21.3 h. The complication rate was 11.7%. Twenty women (9.3%) were lost to follow-up, 82 patients (38.1%) used contraception. Spontaneous pregnancy occurred in 110 out of 113 women who desired fertility (97%). Three patients were defined as infertile but conceived following treatment. The average time between the abortion and the next conception was 15.9 months (range 1-77 months). Seventy patients (63.7%) delivered at term. Premature delivery occurred in 18 patients (16.4%). Eighteen women aborted spontaneously in the first and 3 in the second trimester. One extrauterine pregnancy occurred. Second-trimester abortion with extra-amniotic PGE(2) is a safe procedure with a low rate of complication. Apparently it does not affect future fertility, but may be associated with an increased rate of premature deliveries in future gestations.

Extra-amniotic prostaglandin E2 for midtrimester termination of pregnancy in live fetuses vs. fetal demise.

This study compared the course of midtrimester termination of pregnancies with fetal demise and those with a viable fetuses by extra-amniotic prostaglandin (PG) E(2). A total of 275 women who underwent second trimester abortion with extra-amniotic PGE2(2) were divided into two groups: 95 patients (35%) with fetal demise and 180 women (65%) with a live fetuses. Extra-amniotic PGE2(2) was administered in doses of 200 micro g every 2 h up to 20 doses. Bumm curettage was performed in the majority of the patients. We compared the duration and complication rate between the groups. The median induction to abortion interval was significantly shorter in the fetal demise group (13 vs. 21 h) than in the live fetus group. Mean gestational ages and complication rates were similar. Midtrimester termination of pregnancy with extra-amniotic PGE2(2) is a safe method with a low complication rate. In cases of pregnancy with fetal demise extra-amniotic PGE2(2) is associated with a significantly shorter induction to abortion interval than with a live fetus.

Pregnancy outcome after laparoscopy or laparotomy in pregnancy.

STUDY OBJECTIVE: To assess obstetric performance and fetal outcomes after laparoscopy or laparotomy performed during pregnancy. DESIGN: Nationwide, multicenter, retrospective chart review (Canadian Task Force classification II-2). SETTING: Seventeen hospitals throughout Israel: 12 university or university-affiliated hospitals and 5 general hospitals. PATIENTS: Three hundred eighty-nine pregnant women. INTERVENTION: Laparoscopy or laparotomy for various indications. MEASUREMENTS AND MAIN RESULTS: Of 192 laparoscopies performed, 141 were during the first, 46 during the second, and 5 during the third trimester; respective figures for 197 laparotomies were 63, 110, and 24. No intraoperative complications were reported for either procedure. Six and 25 women had complications after laparoscopy and laparotomy, respectively. There was no significant difference in abortion rates between groups. Mean gestational age at delivery and mean birthweight were comparable between groups. No significant difference was found in frequency of fetal anomalies between groups or when compared with the Israel register of anomalies. CONCLUSION: Operative laparoscopy seems to be as safe as laparotomy in pregnancy.
