Incidental Serous Tubal Intraepithelial Carcinoma Detected by a Surgery for Ectopic Pregnancy

Serous tubal intraepithelial carcinoma is a putative precursor of high-grade serous carcinoma, which is the most common histological type of ovarian or pelvic peritoneal cancer. Serous tubal intraepithelial carcinoma is commonly found in patients with breast cancer susceptibility gene mutations who undergo risk-reducing salpingo-oophorectomy. Incidental serous tubal intraepithelial carcinoma found by a non-prophylactic surgery is rare. A 33-year-old woman referred to our hospital for a diagnosis of ectopic pregnancy. She underwent a laparoscopic right salpingectomy. Pathologically, ectopic pregnancy in the ampulla of the right fallopian tube was confirmed and serous tubal intraepithelial carcinoma was observed in the fallopian tube. Subsequently, she underwent a laparoscopic hysterectomy, bilateral oophorectomy, and left salpingectomy as additional treatment. She has experienced no recurrence thus far for 37 months since the surgery.

Uterine artery embolization in association with methotrexate infusion for the treatment of tubal ectopic pregnancy

Objective To investigate the safety, feasibility, and effectiveness of uterine artery embolization in association with methotrexate(MTX) infusion for the treatment of tubal ectopic pregnancy. Methods Fifty-one patients with tubal ectopic pregnancy were referred for interventional management. All patients received super-selective arteriography of the uterine artery, were infused with 50–100 mg methotrexate(MTX) through a catheter, and underwent embolization of the uterine artery with a gel-foam pledge. Clinical presentation, findings of physical examination, β-HCG values, and the size of the ectopic mass were documented for comparison. The concentration of MTX in blood was evaluated at 0.5, 6, 12, 24, 36, and 48 hours after the procedure. Results Forty-seven out of the 51 patients had clinical resolution of their tubal pregnancy(92.2%). The average time for the β-HCG value to decrease and come back to normal was 9.16 ± 2.54 days(mean +/-SD). MTX levels in peripheral blood could not be detected for patients who received 50 or 75 mg MTX at 36 hours after the procedure, while the MTX level was 0.01 μmol/L at 48 hours after the procedure for patients who received 100 mg. Out of the 4 cases whose ectopic mass size was ≥5 cm, 3 failed to respond to the treatment; however, those whose ectopic mass size was ≤5 cm responded positively to the treatment, regardless of the β-HCG concentration and abdominal bleeding, except for 1 patient who had to undergo laparoscopy for severe abdominal pain and who showed a reduction in her β-HCG level. Conclusion Uterine artery embolization in association with methotrexate infusion is safe and effective in the treatment of tubal ectopic pregnancy, especially for those women with mild to moderate bleeding, or for those at risk of a major hemorrhage. The selection criterion of mass size >5 cm should, therefore, be carefully considered.

Tubal pregnancy with molar degeneration in concurrent eutopic pregnancy. A case report

This research paper presents the infrequent case of a heterotopic pregnancy based on a tubal ectopic pregnancy with molar degeneration in concurrent eutopic pregnancy. Treatment with evacuation/suction curettage and perlaparoscopic salpingectomy was required. This case report confirms what is biologically valid in the statistically unlikely.

Intratubal Methotrexate Injection Combined with Chinese Herbal Medicine for Tubal Pregnancy and Following Pregnancy Prognosis

Objective: To compare the effects of treatment of tubal pregnancy (TP)and its following second pregnancy by intratubal methotrexate injection(IMI) alone and combination of IMI with Chinese herbal medicine. Methods: Thirty-five patients suffering from unruptured TP were divided into two groups at random, to the 19 patients in the treated group, the treatment of combined IMI with Ectopic Pregnancy decoction No. 2 (EP2, a traditional Chinese medical decoction) was applied, and to the other 16 patients in the control group, IMI alone was applied for control. Serum concentrations of human chorionic gonadotro-pinβ(β-HCG), size of the gestational sac, existent time of fetal cardiac beat and peritoneal fluid were measured before and after treatment. And hysterosalpingography were performed 6 months after ending the treatment to verify the presence of tubal obstruction and the condition of relapse.Results: The treatment of all the 35 women was successful. The recovery duration of serumβ-HCG, disappearance duration of TP sac and existent time of peritoneal fluid in the treated group were 20.0±7. 8 days, 1.2±0. 7 months and 10. 7±2. 9 days respectively, which were significantly different from those in the control group (24. 4 ±8.1 days, 3.6±1.7 months and 19.1±3. 2 days respectively(P<0. 05, P<0.01 and P<0. 05 respectively), but the existent time of fetal cardiac beat in the two groups (8.8±1. 9 days vs 9.0±1. 3 days) was not significantly different (P>0.05). The post-treatment oviduct obstructive rate in the two groups was 10.5% and 43.8% respectively, that in the treatment group was less significant (P<0.05). The relapse rate of EP in the treatment group was insignificantly different from that in the control group (5.3% vs 18.8%, P>0.05). Conclusion: The two therapies (IMI alone and IMI combined with EP2) could obtain e-qual efficacy in curing TP. Compared with IMI alone, the combined therapy appears to have the effects of accelerating the resorption of gestational sac and peritoneal fluid, improving the patency of fallopian tube and ameliorating the circumstance of pregnancy, which is favorable to improvement of the re-pregnancy rate and reduction of the re-occurrence of ectopic pregnancy as well as to the enhancement of the effect of IMI in killing trophocytes. But there is not enough proof to show the potency of EP2 in killing embryo.

Tubal Pregnancy with Acute Bleeding Treated by Laparoscopic Surgery: Tips and Case Presentation

Laparoscopic surgery is the standard surgical approach for ectopic pregnancy. However, some surgeons prefer laparotomy for patients with acute bleeding. We evaluated four cases of tubal pregnancy with massive hemoperitoneum (>800 ml) and performed laparoscopic surgery. The patient age ranged from 20 to 37 years, and the gestational age ranged from 5 to 8 weeks. All cases were hemodynamically unstable. Two cases had hemoperitoneum of >2000 mL, which was caused by the rupture of the left isthmus tube. In three cases, surgery could be started within approximately 30 min, and in one case, the start time extended owing to difficulty in anesthesia introduction. Moreover, in three cases, the target lesion was reached within 7 min, and the lesion was excised in approximately 20 min from the start of insufflation, and in one case with a lesion exceeding 7 cm, the time extended. All patients were safely treated via laparoscopic surgery. To initiate surgery without deterioration of the hemodynamic condition, blood transfusion can be started simultaneously with preparation for laparoscopic surgery. Lifting the lesion with a pair of forceps can help immediately stop bleeding, even if it is difficult to secure the visual field owing to massive bleeding. When there is difficulty in anesthesia or a large pregnancy lesion, care should be taken to avoid an increase in the amount of bleeding associated with extension of the perioperative period.

Management of Ectopic Pregnancy in a Broad Ligament and Recurrent Tubal Pregnancy: A Case Report

Broad ligament pregnancy is a rare event and always delays in diagnosis. A pregnant woman in early twenties presented for our center. Routine ultra-sonography revealed a first trimester abdominal pregnancy. Broad ligament pregnancy was diagnosed intraoperation and treated with laparoscopic resection successfully. The patient has a history of right tubal pregnancy 2 years ago and terminated with Laparoscopic Salpingostomy. According to the long term followed-up for the patient, we found that she had recurrent right tubal pregnancy 5 months after the broad ligment ectopic pregnancy. She received the salpingectomy laparoscopically. We presented the case to discuss the clinical management of broad ligament ectopic pregnancy and options of surgical treatments of tubal pregnancy to reduce the risk of recurrent.

Recurrent tubal pregnancy following ipsilateral partial salpingectomy

A 34-year-old woman came into the Emergency Department of PUMCH with the complaint of sudden lower abdominal pain lasting 4 hours on May 1st, 2004. She had normal menstruation cycle with a period of 30 days. But her last menstruation was started 37 days ago. She experienced laparosalpingectomy for right tubal pregnancy on Jan. 23rd, 2003. During that operation, it was found that she had pelvic adhesions in the Douglas pouch.

Management and Results of Ectopic Pregnancy Adapted by Clinical Guidelines: Two Years Experience of University Hospital in Turkey

Ectopic pregnancy is defined as the fertilized ovum implants in a location outside the endometrial cavity, remains to be an important cause of maternal morbidity and mortality worldwide and is a health problem with incidence ranges between 0.25% and 2% of all pregnancies. In our study, in Izmir Katip Celebi University Ataturk Training and Research Hospital, Department of Obstetrics and Gynecology from 2011 to 2013, 96 cases with diagnosis of ectopic pregnancy managed by the adapted RCOG’s Guide were analyzed retrospectively. The data were analyzed as follows: age, the history of operation, smoking, the presence of intrauterine device, blood groups, hemoglobin, platelets, values of B-hCG, the diagnostic interval, intra-abdominal free fluid and/or acute abdomen, the method of treatment and the success of treatment.

Contralateral Tubal Ectopic Pregnancy after Ovulation of Another Side Ovary in Spontaneous Cycles:A Case Report and Review of the Literature

Pregnancies in the same side tube after the same side ovary ovulation are more common. We report an unusual case of contralateral tubal ectopic pregnancy after ovulation of another side ovary in spontaneous cycles. A 32-year-old woman underwent laparoscopic left fallopian tube conservative surgery because of left tubal pregnancy two years ago. She returned to our hospital with a positive pregnancy test and lower abdominal pain 28 d after the dominant follicle discharged in the right side ovary detected by transvaginal ultrasound in spontaneous cycles. Transvaginal ultrasonography revealed no intrauterine gestational sac but a left adnexal mass measuring 2.6 cm X2.5 cm. Videolaparoscopy was performed, and the diagnosis of an ectopic pregnancy in the let fallopian tube was confirmed by pathologic report. Tubal damage is the most important risk factor for tubal ectopic pregnancy. Embryos can be reversely migrated toward fallopian tubes, due to retrograde action of endometrial waves and uterine contractions, that is another necessary reason which contributes to such tubal pregnancy. Total salpingectomy or tubal sterilization is necessary for avoiding repeated tubal ectopic pregnancy.

Tubal Pregnancy Treated with Trichosanthin and Followed up by Hysterosalpingography

Twenty cases of unruptured tubal pregnancy were treated with trichosanthin intramuscularly.Only two cases were eventoally operated, so the effective rate was 90% . Hysterosalpingography was takenin 14 of 18 cases who was willing to accept the procedure at 0. 5- 1.5 year after the conservative treatment.Both tubes were patent in 10 of 14 cases, the rate of patency was 71.4% .

The Galectin-9/Tim-3 pathway is involved in the regulation of NK cell function at the maternal-fetal interface in early pregnancy

Decidual natural killer （dNK） cells actively participate in the establishment and maintenance of maternal-fetal immune tolerance and act as local guardians against infection. However, how dNK cells maintain the immune balance between tolerance and anti-infection immune responses during pregnancy remains unknown. Here, we demonstrated that the inhibitory molecule T-cell immunoglobulin domain and mucin domain-containing molecule-3 （Tim-3） are expressed on over 60% of dNK cells. Tim-3^＋ dNK cells display higher interleukin （IL）-4 and lower tumor necrosis factor （TNF）-α and perforin production. Human trophoblast cells can induce the transformation of peripheral NK cells into a dNK-like phenotype via the secretion of galectin-9 （Gal-9） and the interaction between Gal-9 and Tim-3. In addition, trophoblasts inhibit lipopolysaccharide （LPS）-induced pro-inflammatory cytokine and perforin production by dNK cells, which can be attenuated by Tim-3 neutralizing antibodies. Interestingly, a decreased percentage of Tim-3-expressing dNK cells were observed in human miscarriages and murine abortion-prone models. Moreover, T helper （Th）2-type cytokines were decreased and Thl-type cytokines were increased in Tim-3^＋ but not Tim-3- dNK cells from human and mouse miscarriages. Therefore, our results suggest that the Gal-9/Tim-3 signal is important for the regulation of dNK cell function, which is beneficial for the maintenance of a normal pregnancy.

Factors associated with the incidence of ectopic pregnancy in women undergoing assisted reproductive treatment

Background:Ectopic pregnancy(EP)is a common complication in women undergoing assisted reproductive treatment,but the underlying causes for this remain unclear.This study aimed to explore factors affecting the incidence of EP in in vitro fertilization(IVF)/intracytoplasmic sperm injection(ICSI).Methods:This was a retrospective study on the incidence of EP in IVF/ICSI cycles between January 1,2013 and December 31,2017.Patient age,infertility diagnosis(tubal factor or not),primary or secondary infertility,type of cycle(frozen-thawed or fresh),type of embryo(s)transferred(cleavage embryo or blastocyst),number of embryos transferred(one,two,or three),previous history of EP,and endometrial combined thickness were analyzed to explore their relationships with the incidence of EP.Based on clinical typing results,the patients were divided into an EP group or a non-EP group.Categorical variables were analyzed using Chi-squared test or Fisher exact test.Logistic regression analysis was performed to explore their associations with the incidence of EP.Results:The percentage of patients with primary infertility in EP group was significantly lower than that in non-EP group(31.3%vs.46.7%,χ^2=26.032,P<0.001).The percentage of patients with tubal infertility in EP group was also significantly higher than that in non-EP group(89.2%vs.63.6%,χ^2=77.410,P<0.001).The percentages of patients with transfer of cleavage-stage embryo or blastocyst(91.4%vs.84.4%,χ^2=10.132,P=0.001)and different endometrial combined thickness(ECT)(χ^2=18.373,P<0.001)differed significantly between EP and non-EP groups.For patients who had a previous history of one to four EPs,the percentage of patients undergoing transfer of a cleavage-stage embryo was significantly higher in EP group than that in non-EP group(92.2%vs.77.6%,χ^2=13.737,P<0.001).In multivariate logistic regression analysis,tubal infertility was strongly associated with EP(adjusted odds ratio:3.995,95%confidence interval:2.706-5.897,P<0.001).Conclusions:In IVF/ICSI cycles,transfer of a blastocyst-stage embryo,especially for patients with a previous history of EP,reduced the rate of EP.Tubal infertility was strongly associated with EP.

In vitro fertilization-embryo transfer in patients with unexplained recurrent pregnancy loss

Background:Empiric therapy for patients with unexplained recurrent pregnancy loss(URPL)is not precise.Some patients will ask for assisted reproductive technology due to secondary infertility or advanced maternal age.The clinical outcomes of URPL patients who have undergonein vitro fertilization-embryo transfer(IVF-ET)require elucidation.The IVF outcome and influencing factors of URPL patients need further study.Methods:A retrospective cohort study was designed,and 312 infertile patients with URPL who had been treated during January 2012 to December 2015 in the Reproduction Center of Peking University Third Hospital were included.By comparing clinical outcomes between these patients and those with tubal factor infertility(TFI),the factors affecting the clinical outcomes of URPL patients were analyzed.Results:The clinical pregnancy rate(35.18%vs.34.52%in fresh ET cycles,P=0.877;34.48%vs.40.27%in frozen-thawed ET cycles,P=0.283)and live birth rate(LBR)in fresh ET cycles(27.67%vs.26.59%,P=0.785)were not significantly different between URPL group and TFI group.URPL group had lower LBR in frozen-thawed ET cycles than that of TFI group(23.56%vs.33.56%,P=0.047),but the cumulative LBRs(34.69%vs.38.26%,P=0.368)were not significantly different between the two groups.The increased endometrial thickness(EMT)on the human chorionic gonadotropin day(odds ratio[OR]:0.848,95%confidence interval[CI]:0.748-0.962,P=0.010)and the increased number of eggs retrieved(OR:0.928,95%CI:0.887-0.970,P=0.001)were protective factors for clinical pregnancy in stimulated cycles.The increased number of eggs retrieved(OR:0.875,95%CI:0.846-0.906,P<0.001),the increased two-pronucleus rate(OR:0.151,95%CI:0.052-0.437,P<0.001),and increased EMT(OR:0.876,95%CI:0.770-0.997,P=0.045)in ET day were protective factors for the cumulative live birth outcome.Conclusion:After matching ages,no significant differences in clinical outcomes were found between the patients with URPL and the patients with TFI.A thicker endometrium and more retrieved oocytes increase the probability of pregnancy in fresh transfer cycles,but a better normal fertilization potential will increase the possibility of a live birth.

FH 17 cells in human recurrent pregnancy loss and ~re-eclampsia

T helper 17 （TH 17） cells have been identified as a new lineage of helper T cells and have been shown to be important in host defense against extracellular infectious agents, autoimmune disease and chronic inflammatory diseases. Recently, TH17 cells have also been shown to participate in successful pregnancy, as well as in the pathogenesis of diseases of pregnancy, such as recurrent spontaneous abortion （RSA） and pre-eclampsia （PE）. Here, we review our current knowledge of TH 17 cells in human RSA and PE. We also discuss how the local uterine microenvironment affects the differentiation of TH17 cells and the mechanisms that regulate TH17 cells during pregnancy. Research into TH17 cells will not only advance our understanding of TH 17-related pregnancy complications, but will also facilitate the design of novel therapies for reproductive diseases.

The Expression and Change of the β_3 Integrin Subunit and Fibronectin in Normal Human Oviductal Tissue and Tubal Ectopic Pregnant Tissue

Objective To investigate the expression and change of the β3 integrin subunit and fibronectin in normal human oviductal tissue during various phases of the menstrual cycle and tubal ectopic pregnant tissueMethods Samples of normal ( n=29 ) and pregnant fallopian tube ( n=22 ) tissues were obtained from women who had normal cycle and history of normal pregnancy. Normal oviductal tissue samples were divided into 4 groups based on their menstrual cycle. Both expression and distribution of the β3 subunit and fibronectin were determined with the immunohistochemical method and the image analysis.Results The β3 subunit was expressed in the cytoplasm of ciliated cells. The expression level of the β3 subunit was higher after ovulation than that before ovulation in isthmus epithelium (P<0.001), and declined significantly after ovulation in ampullae epithelium (P<0.001). In umbrella epithelium within 4 days after ovulation, the expression level of the β3 subunit was observed at rather higher level among other phases (P <0.001). The ciliated and secretory cells of the epithelium except for where the pregnancy occurred in tubal pregnancy expressed the β3 subunit, and no significant relationship was found between the normal tubal tissue of the secretory phase and tubal ectopic pregnant tissue (P>0.05). Fibronectin was expressed in the basement membrane of human oviductal epithelium and matrix. The expression level of fibronectin was higher in the hyperplastic phase than that in the secretory one (P<0.001). And it was lower in normal tubal tissue of the secretory phase than that in tubal ectopic pregnant tissue (P<0.001).Conclusion Theβ3 integrin subunit was expressed in the ciliated cells of human oviductal epithelium, and fibronectin was expressed in the basement membrane of human oviductal epithelium and matrix. Their expression and change in oviductal tissue is based on different phases of menstrual cycle. The β3 subunit could not related to the occurrence of tubal ectopic pregnancy. Fibronectin could be the potential molecular basis for the tubal ectopic pregnancy.
