RESUMEN
BACKGROUND: The diagnostic criteria of chronic endometritis remain controversial in the treatment for infertile patients. METHODS: A prospective observational study was conducted in a single university from June 2014 to September 2017. Patients who underwent single frozen-thawed blastocyst transfer with a hormone replacement cycle after histological examination for the presence of chronic endometritis were enrolled. Four criteria were used to define chronic endometritis according to the number of plasma cells in the same group of patients: 1 or more (≥ 1) plasma cells, 2 or more (≥ 2), 3 or more (≥ 3), or 5 or more (≥ 5) in 10 high-power fields. Pregnancy rates, live birth rates, and miscarriage rates of the non-chronic endometritis and the chronic endometritis groups defined with each criterion were calculated. A logistic regression analysis was performed for live births using eight explanatory variables (seven infertility factors and chronic endometritis). A receiver operating characteristic curve was drawn and the optimal cut-off value was calculated. RESULTS: A total of 69 patients were registered and 53 patients were finally analyzed after exclusion. When the diagnostic criterion was designated as the presence of ≥ 1 plasma cell in the endometrial stroma per 10 high-power fields, the pregnancy rate, live birth rate, and miscarriage rate were 63.0% vs. 30.8%, 51.9% vs. 7.7%, and 17.7% vs. 75% in the non-chronic and chronic endometritis groups, respectively. This criterion resulted in the highest pregnancy and live birth rates among the non-chronic endometritis and the smallest P values for the pregnancy rates, live birth rates, and miscarriage rates between the non-chronic and chronic endometritis groups. In the logistic regression analysis, chronic endometritis was an explanatory variable negatively affecting the objective variable of live birth only when chronic endometritis was diagnosed with ≥ 1 or ≥ 2 plasma cells per 10 high-power fields. The optimal cut-off value was obtained when one or more plasma cells were found in 10 high-power fields (sensitivity 87.5%, specificity 64.9%). CONCLUSIONS: Chronic endometritis should be diagnosed as the presence of ≥ 1 plasma cells in 10 high-power fields. According to this diagnostic criterion, chronic endometritis adversely affected the pregnancy rate and the live birth rate.

BACKGROUND: The presence of chronic deciduitis (CD) was determined in patients diagnosed with or without chronic endometritis (CE) before pregnancy. OBJECTIVE: To study the effect of CE on decidua in cases of miscarriage. METHODS: Decidual tissue was obtained from the patients who miscarried at the first pregnancy within a year after the diagnosis of the presence or absence of CE. The number and distribution pattern of plasma cells stained with CD138 in decidual tissue in 10 high-power fields (HPFs) was examined. The prevalence of CD diagnosed with four different grade; grade 0, no plasma cell in 10 HPFs, thus Non-CD;grade 1, rare single plasma cells; grade 2, rare clusters or more than 5 single cells total; and grade 3, many plasma cells with more than 5 clusters, were examined and compared between Non-CE and CE. RESULTS: The incidence rate of CD of grade2 + 3 was significantly higher in CE than Non-CE (53.8%; 7/13 vs. 0%; 0/13, P < 0.01). Presence of clusters or a number of plasma cells in 10 HPFs of decidua showed a sensitivity of 53.8%, a specificity of 100%, a positive predictive value of 100%, and a negative predictive value of 68.4% for the diagnosis of CE. CONCLUSION: Presence of clusters of plasma cells or five or more of plasma cells in decidua was found in more than half of CE, but not found in Non-CE. When CD with cluster or five or more of plasma cells is confirmed histologically in miscarriage decidual tissue, the presence of CE before the pregnancy should be suspected.

The uterus is an organ for raising the fetus, and its lumen is lined by the endometrium. The endometrium is an important site for the implantation and maturation of fertilized eggs. The endometrium undergoes repetitive proliferation, maturation (decidualization), and exfoliation changes every menstrual cycle. At the same time, the number and type of endometrial immunocompetent cells vary during the menstrual cycle. At the implantation stage, the immunocompetent cells occupy approximately half of the endometrial cells. Immunocompetent cells normally eliminate pathogenic microorganisms to protect the body; however, they also promote immune tolerance to accept the fetus during pregnancy. The immunocompetent cells in the uterus can perform both these functions. With the establishment of pregnancy, stimuli from the trophoblast (placenta) and fetus can also change the immune environment of the uterus, and pregnancy can be maintained only when the immune system is well adapted to the stimuli of some hormones and the fetus. Immunity for the establishment of pregnancy is not simple because multiple immunocompetent cells are involved in establishing and maintaining pregnancy. To understand the immune mechanisms associated with the establishment of pregnancy, we have to learn about each immune cell. This review, therefore, discusses the roles and distribution of the immunocompetent cells inside the uterus during menstruation and early pregnancy.

AIM: Chronic endometritis (CE) is a disease of continuous and subtle inflammation characterized by the infiltration of plasma cells in the endometrial stromal area. Although the clinical significance of CE has been thought in clinical practice for a long time because it is either asymptomatic or presents with subtle symptoms, recent studies have shown the potential adverse effects of CE on fertility. In the present review, we focus on the concept, diagnosis, etiology, pathophysiology, diagnosis, impact on reproduction and treatment for it to understand CE. METHODS: The published articles were reviewed. RESULTS: The prevalence of CE has been found to be 2.8-56.8% in infertile women, 14-67.5% in women with recurrent implantation failure (RIF), and 9.3-67.6% in women with recurrent pregnancy loss. Microorganisms are thought to be a main cause of CE, since antibiotic treatment has been reported to be an effective therapy for CE. Common bacteria are frequently detected in the uterine cavity of CE patients by microbial culture. In CE endometrium, the prevalence of immune cells and decidualization has been reported to be modified, and these modifications are thought to adversely affect fertility. The gold standard for the diagnosis of CE is the histological detection of plasma cells in the stromal area of the endometrium in endometrial specimens, although universally accepted criteria for the diagnosis of CE have not been determined. The treatment currently thought to be most effective for the recovery of fertility in CE is administration of oral antibiotics. Patients whose CE has been cured have been reported to have a higher ongoing pregnancy rate, clinical pregnancy rate, and implantation rate compared with patients with persistent CE. CONCLUSION: CE greatly affects implantation and impairs fertility. Antibiotic administration is an effective therapeutic option. Pregnancy rate in in vitro fertilization is improved when CE is cured by antibiotic.

Transverse uterine fundal cesarean section in cases of total placenta previa reduces blood loss, but its influence on subsequent pregnancies, including the uterine rupture risk, remains unclear. We report a case of uterine rupture due to placenta percreta in the first trimester in a 43-year-old woman who underwent transverse uterine fundal incision in a previous pregnancy (at 40 years old). The patient did not undergo assessment of the uterine scare after the previous operation. Oocyte donation and in vitro fertilization at another institution resulted in the current pregnancy. At 11 weeks 3 days, she was admitted to the emergency department because of sudden severe abdominal pain. Ultrasound showed massive accumulation of free fluid in the peritoneal cavity and the fetus was outside the uterine cavity; uterine rupture was diagnosed. During emergency laparotomy, the uterine rupture was detected at exactly the previous incision site; a total hysterectomy was performed. Pregnancy after a transverse uterine fundal cesarean section is at high risk. As uterine scar dehiscence might have caused the uterine rupture, wounds should be evaluated before allowing subsequent pregnancies.

AIM: Cesarean scar syndrome (CSS) is characterized by increased risk of postmenstrual abnormal uterine bleeding, dysmenorrhea, and infertility, due to a post-cesarean scar defect known as an isthmocele. This study aimed to assess the impact of hysteroscopic surgery on isthmocele associated with CSS. METHODS: Eighteen patients with CSS were enrolled. Surgical methods included resection of the inferior edge and superficial cauterization of the isthmocele via hysteroscopic surgery. We evaluated the residual myometrial thickness and isthmocele volume using magnetic resonance imaging, before and after hysteroscopic surgery. RESULTS: All patients underwent surgery without any complications. The residual myometrium was thicker after hysteroscopic surgery (median: 2.1 mm and 4.2 mm, before and after surgery, respectively; P = 0.0001). Isthmocele volume was significantly reduced after hysteroscopic surgery (median: 494.9 mm3 and 282.8 mm3 , before and after surgery, respectively; P = 0.0016). CONCLUSION: This study demonstrated that hysteroscopic surgery is effective in increasing the residual myometrial thickness and reducing the size of isthmocele.

BACKGROUND: Chronic endometritis (CE) is a continuous inflammation of uterine endometrium, and it is usually symptomless. As CE has been thought not to affect the reproductive status and general health of affected women, its significance has not been explored. However, recent studies have shown that CE is related with repeated implantation failures after in vitro fertilization-embryo transfer, unexplained infertility, and recurrent miscarriages. As decidua differentiates to support the implantation process and maintains the pregnancy, we hypothesized that CE may influence the process of decidualization. METHODS: Seventeen patients were employed in the experiment involving culture of endometrial stromal cells (ESCs). After obtaining endometrial samples, ESCs were harvested and cultured for 13 days. The concentrations in culture media and the protein expressions in ESCs of prolactin (PRL) and insulin-like growth factor binding protein-1 (IGFBP-1), two well known decidualization markers used in a large number of in vitro models, were analyzed by ELISA and Western blotting, respectively, and the cell numbers were also counted. The mRNA levels of PRL and IGFBP-1 were tested by quantitative real time polymerase chain reaction (RT-PCR). Since sex hormone induce proliferation and differentiation to decidua via binding to the sex hormone receptors (ERα, ERß, PRA, and PRB), their expression was assessed in another 17 patients' paraffin-embedded endometrial tissue specimens by immunohistochemistry and semi-quantified by H-score. RESULTS: Increased cell numbers and reduced secretion of PRL and IGFBP-1 were detected by ELISA in the ESCs of CE patients after culture for 13 days compared with non-CE patients. The decreased protein expression of IGFBP-1 in ESCs of CE patients was detected by Western blotting. The decreased expression of PRL mRNA and IGFBP-1 mRNA were detected by RT-PCR. Increased expressions of ERα, ERß, PRA, and PRB were observed in the stromal cells of CE patients in comparison to non-CE patients, whereas increased expressions of ERα and ERß were detected in the glandular cells of CE. CONCLUSION: Our data suggests that CE modifies decidualization of human ESC through untuning the function of sex steroid hormone receptor.

Pyoderma gangrenosum (PG) is a rare ulcerative skin disease that usually starts as a pustular lesion and rapidly progresses to a painful ulcer with undermined violaceous borders. The occurrence of PG during pregnancy is uncommon. We describe a case of a pregnant patient with PG who was diagnosed as having ulcerative colitis after delivery. Obstetricians need to understand the pathogenesis of PG and its associated conditions because it is important to make a proper diagnosis and provide targeted therapy.

Aim: To clarify the effects of small endometriomas on in vitro fertilization (IVF) outcomes. In the present study, the potential impact of small ovarian endometriomas on the quantitative and qualitative outcomes of IVF was evaluated in the same individual. Methods: A retrospective analysis was performed, in which 118 infertile women with unilateral endometriomas that were <40 mm in size and who underwent IVF or intracytoplasmic sperm injection were evaluated. Single frozen embryo transfer cycles were performed, with separate data collections for both the affected and the unaffected ovaries, which allowed for an evaluation of the implantation rate. Results: The mean antral follicular count and the number of follicular flushings, retrieved oocytes, and obtained embryos were significantly lower for the endometrioma-containing ovary than for the contralateral, intact ovary. No significant difference was observed regarding the blastocyst retrieval and good-quality blastocyst retrieval rates, pregnancy rate, and clinical pregnancy or live birth rate. Conclusion: Although the patients with a small endometrioma had a decreased ovarian reserve, they had lower pregnancy rates. The decision to transfer an embryo from an endometrioma-containing ovary or from a contralateral, intact ovary also might not influence the pregnancy rate.
RESUMEN
Laparoscopy for intra-abdominal exploration and tissue sampling is useful in advanced ovarian cancers, in which it is presumed to be difficult to achieve complete tumour reduction in the initial surgery. This is a report of a case of suspected advanced ovarian cancer in a patient, who underwent laparoscopic screening and was later pathologically diagnosed with tuberculous peritonitis. A woman in her 50s visited her local doctor with constipation. Since imaging showed massive ascites she was referred for further evaluation. We initially suspected advanced ovarian cancer due to the presence of massive ascites and multiple peritoneal nodules. However, histopathological examination indicated that the nodules were tubercles, and the patient was subsequently diagnosed with tuberculous peritonitis. It is important to be aware that tuberculosis peritonitis can be misdiagnosed or mistaken for advanced ovarian cancer. Preoperative diagnosis of tuberculous peritonitis is often difficult. Tuberculous peritonitis should be considered if intraoperative findings show diffuse nodular disseminated lesions.

Uterine natural killer (uNK) cells remarkably increase in number after implantation. NK cells or their precursors migrate from the blood stream and contribute to the increase. However, the contribution of uNK cells present in the virgin uterus has been unclear. To elucidate this issue, we examined uterine leukocyte subsets during pregnancy in BALB/c mice. The most dramatic change was the massive decrease in CD11bâ» or Gr-1â» cells at gestation day (gd) 6. Uterine NK cells at gd 0 were CD11bâ», and severely decreased at gd 6. The decrease was selective, and the proportion of other cells examined did not decrease. Uterine NK cells almost recovered at gd 12. These cells at gd 12 were more mature and/or activated in terms of expression of CD11b, CD27, CD127, or B220 than at gd 0. CXCL12 expression was observed on uterine cells at gd 0 or 6, but not at gd 12, whereas CXCR4 was detected on uNK cells at gds 0 and 12. A much higher expression of IL-15 in uterine cells or interferon-gamma expression in uNK cells was observed at gd 12 than at gd 0. IL-15 receptor alpha chain was detected on uNK cells at gd 12, but not at gd 0. Taken together, these findings were consistent with our interpretation that uNK cells present at gd 0 do not contribute to the increase of uNK cell number after implantation, and NK cells or their precursors migrate into the uterus, mature, and produce interferon-gamma to support pregnancy.

Polycystic ovary syndrome (PCOS) is one of major causes of irregular menstruation. It is defined as a condition involving the combination of hyperandrogenism and chronic oligomenorrhea or anovulation, and is thought to have a variety of etiologies. Insulin resistance (impaired insulin sensitivity) has been suggested to be one of the etiologies of PCOS. PCOS patients often need to take medication to treat anovulation and infertility. Therefore, it would be beneficial to patients if simple non-pharmacological treatments can be developed. Recently the efficacy of vinegar to improve insulin resistance has been reported. To study the effect of vinegar on metabolic and hormonal indices and ovulatory function in PCOS, seven patients seeking a non-pharmacological treatment for PCOS took a beverage containing 15 g of apple vinegar daily for 90 to 110 days. Ovulation, the menstrual interval, fasting serum glucose level, fasting serum insulin level, luteinizing hormone (LH), follicle stimulating hormone (FSH), and testosterone were compared before and after intake of the vinegar beverage. Intake of the vinegar beverage resulted in a decrease of the homeostasis model assessment insulin resistance index (HOMA-R) in six patients, as well as a decrease of the LH/FSH ratio in five of seven patients. Ovulatory menstruation was observed within 40 day in four of seven patients. These findings suggest the possibility of vinegar to restore ovulatory function through improving insulin sensitivity in PCOS patients, thus, avoiding pharmacological treatment. Intake of vinegar might reduce medical cost and treatment time for insulin resistance, anovulation, and infertility in patients with PCOS.

AIM: The aim of this study was to assess the effect of coagulation versus suture used for hemostasis during laparoscopic excision of a unilateral endometrioma for outcome of in vitro fertilization (IVF). MATERIAL AND METHODS: This retrospective study was set in a university hospital. A total of 44 sterile patients underwent laparoscopic excision of a unilateral ovarian endometrioma. Bipolar electrocoagulation was performed for hemostasis in 21 patients and the remaining 23 patients underwent suturing. Samples of blood were taken on day 3 of menstruation before the operation. Serum levels of anti-Müllerian hormone, follicle-stimulating hormone and estradiol were measured. Number of antral follicles, follicular flushings, oocytes retrieved, and embryos were counted and the outcomes of IVF were recorded. RESULTS: No significant differences in the serum levels of any of the hormones were found between the pre- and postoperative samples, in either group. The mean antral follicle count, number of follicular flushings, oocytes retrieved and embryos obtained were significantly lower in the treated ovary as compared with the corresponding values in the contralateral intact ovary in the suture group. The pregnancy rates were similar in the two groups. CONCLUSIONS: There was no difference in the outcome of IVF between the two different methods of hemostasis.

Rice bran water extract (RBWE) and ethanol extract (RBEE) at 1.0 mg/ml markedly inhibited the proliferation of LS174T human colon cancer cells. RBEE but not RBWE induced apoptosis. RBWE promoted the production of intestinal mucin (MUC2). Real-time RT-PCR demonstrated that RBWE up-regulated the expression of MUC2 and sucrase-isomaltase complex (a differentiation marker of colon cancer cells), and attenuated that of proliferating cell nuclear antigen at the mRNA level in a dose-dependent manner. These findings suggested that RBWE suppress the proliferation of colon cancer cells by inducting differentiation not apoptosis.
RESUMEN
AIMS: Laparoscopy has been performed in women with unexplained infertility, but the recent trend is to commence in vitro fertilization (IVF) without prior laparoscopy. The aim of this study was to determine whether or not laparoscopic surgery is necessary for these patients. MATERIAL & METHODS: With a diagnosis of unexplained infertility, 51 women underwent laparoscopic surgery followed by IVF (laparoscopy group) and 41 women underwent IVF without prior laparoscopy (IVF group). We reviewed these two groups retrospectively and evaluated the cumulative pregnancy rate. RESULTS: In the laparoscopy group, 16 of the 51 women became pregnant spontaneously soon after surgery. Twenty-three patients became pregnant with IVF. In the IVF group, 32 patients became pregnant with IVF. Two of the 41 women became pregnant spontaneously while waiting to commence IVF. CONCLUSION: Laparoscopy should be offered as an option for younger patients who desire spontaneous pregnancy because there was no significant difference of the cumulative pregnancy rate between the groups.

PROBLEM: Chronic endometritis (CE) influences the clinical outcomes of assisted reproductive technology. However, the effect of CE on the pregnancy outcome is still unknown. METHOD OF STUDY: A retrospective case-control study was conducted in a single university. Subjects who conceived by in vitro fertilization within a year after a histological diagnosis of CE under 40 years of age from September 2013 to December 2017 were extracted. The rates of miscarriage, preterm birth, term birth, and live birth per pregnancy according to the presence or absence of CE were analyzed. A logistic regression analysis was performed for miscarriage, preterm birth, term birth, and live birth for eight explanatory variables of seven infertility factors and CE. RESULTS: A total of 39 pregnancies in 38 subjects with non-CE and 35 pregnancies in 32 subjects with CE were ultimately analyzed. The rates of miscarriage, preterm birth, term birth, and live birth per pregnancy were 12.8% and 40.0% (P < .03), 2.6% and 14.3% (P = .1), 84.6% and 45.7% (P < .001) and 84.6% and 57.1% (P < .03) in the Non-CE and CE groups, respectively, although only the analysis for tem birth rate had sufficient power to exclude Type II error. In logistic analysis, CE was a factor affecting the objective variables of miscarriage, term birth, and live birth. CONCLUSIONS: The term birth rate among pregnancies decreased mainly due to an increase in miscarriages when CE was detected before pregnancy in patients treated with in vitro fertilization. A histopathological diagnosis of CE adversely affected the term birth rate per pregnancy.

INTRODUCTION: Female urinary retention is rare. CASE PRESENTATION: Case 1, a 35-year-old nulliparous woman, and case 2, a 47-year-old nulliparous woman, had transient urinary retention. A urodynamics revealed increased bladder sensation in case 1 and detrusor underactivity with a large post-void residual in cases 1 and 2. Both women had a uterine leiomyoma of >10 cm in diameter. Soon after extraction of the tumor, retention episodes disappeared completely in case 1. CONCLUSION: Although rare, uterine leiomyoma should be listed as a cause of female detrusor underactivity.
RESUMEN
AIM: To retrospectively assess the long-term outcome, including pregnancy rate, recurrence rate and ovarian reserve, after laser ablation surgery in infertile women with endometrioma. METHODS: From March 1997 to June 2007, 45 subfertile women underwent ablation surgery with a potassium-titanyl-phosphate laser for ovarian endometrioma. These patients were reviewed retrospectively. RESULTS: Of the 45 women, 22 became pregnant spontaneously. Among the 23 women who did not become pregnant after more than 6 months postoperatively, 16 elected to undergo in vitro fertilization (IVF), 12 of them became pregnant. The remaining 11 women did not become pregnant. Eleven women had recurrence detected by ultrasound. The mean number of oocytes retrieved per cycle during IVF was 7.3 +/- 3.6 and 4.6 +/- 2.7 from the ovary treated by ablation surgery and the contralateral ovary, respectively. CONCLUSION: The overall long-term pregnancy rate (combining spontaneous pregnancy and IVF) after laparoscopic ablation surgery for endometrioma was 75.6%. Surgery did not have any adverse effect on the ovarian reserve during subsequent IVF.

Having a uterine scar places a woman at increased risk of complications, such as Cesarean scar pregnancy (CSP), uterine rupture, placenta previa, and placenta accreta, in subsequent pregnancies. We report a case of uterine rupture at 11 weeks of gestation in a woman with a previous Cesarean section. A 43-year-old woman with a history of abdominal myomectomy and Cesarean section had her pregnancy induced by in vitro fertilization with donor eggs. The exact location of the gestational sac was identified on her first day of hospitalization, and her pregnancy was suspected to be a CSP. The following day, the patient complained of sudden lower abdominal pain. A uterine scar rupture was diagnosed, and an emergency surgery was required. It may be that first-trimester screening could allow the early recognition of patients at risk for these perinatal complications.
RESUMEN
BACKGROUND: Anti-NMDA-R receptor encephalitis occurs predominantly in younger women and is often comorbid with ovarian teratoma, a feature that is often absent in children. Here, we report our experience with two pediatric patients, in whom no tumors were present during treatment for encephalitis, but in whom ovarian teratomas developed without encephalitis relapse after treatment was completed. CASES: Patient 1 was a 14-year-old girl who was diagnosed due to characteristic symptoms and anti-NMDA-R antibody. MRI scanning during treatment revealed no ovarian tumors, but a tumor developed in the right ovary 10months after onset. Another tumor developed in the left ovary 3years after onset, and a mature ovarian teratoma was confirmed after bilateral partial ovariectomy. Patient 2 was an 11-year old girl who was also diagnosed due to characteristic symptoms and anti-NMDA-R antibody. Imaging during treatment revealed no ovarian tumors, but a 2.5-cm tumor mass was found in the left ovary 10months after onset, and a mature ovarian teratoma was confirmed after partial ovariectomy. DISCUSSION: This case report suggests the need for regular tumor screening after treatment for anti-NMDA receptor encephalitis because of potential subsequent tumor development, even in pediatric patients who initially present with no comorbid tumors. No analysis of relapse risk has yet been reported in cases of tumor development after treatment, and at this point, whether or not resection is needed to prevent relapse remains unclear. However, because teratomas usually grow, have an associated risk of torsion, and can be malignant, tumor removal should be considered.
