Successful Management of Uterine Prolapse in Pregnancy: A Case Report of Avoiding a Cervical Laceration by the Reduction of Massive Edema.

We report a case of uterine prolapse in pregnancy, which was successfully managed before delivery. A 35-year-old woman (G2P1) complained consistently of a protruding uterus at 36 weeks gestation, and an engorged uterine cervix without tenderness, urinary disturbance, and incontinence were recognized (Pelvic Organ Prolapse Quantification (POP-Q) score C: +7). Manual retraction of the edematous cervix was gently performed with gauze packing, and strikingly improved edema of the cervix with a POP-Q score of C: -2 was observed one day after the gauze packing. Induction of labor was planned due to a suspected large-for-gestational-age infant, and the patient uneventfully delivered at 39 weeks gestation without any obstacles to delivery and cervical laceration. Cervical edema in pregnancy increases the risk of cervical dystocia and cervical lacerations. However, lacerations with edema are predicted to have a poor wound-healing process. The technique with gauze packing presented in this case may be useful in the protective handling of the uterine cervix during pregnancy.

Exploring the Impact of Endometrioma Aspiration and Dienogest Combination Therapy on Cyst Size, Inflammatory Cytokines in Follicular Fluid and Fertility Outcomes.

Endometriomas (chocolate cysts) are cystic lesions that can develop on ovaries, and are characterized by the presence of ectopic endometrial tissue or similar tissue. Such lesions can cause a decline in the number and quality of oocytes, and lead to implantation failure. In this study, we retrospectively assessed the efficacy of repeated endometrioma aspiration and dienogest combination therapy in patients suffering endometriosis-associated infertility with endometriomas. A comparison was made between a treated group that underwent combination therapy followed by controlled ovarian hyperstimulation (COH) (n = 30) and a control group that did not undergo treatment (n = 40), at the IVF Osaka Clinic from September 2019 to September 2021. There were no differences in patient background between the two groups. A reduction in endometrioma size continued for 12 months after treatment. The numbers of follicles that developed to 15 mm or greater in size following COH and mature oocytes were significantly lower in the treated group compared to those in the control group. The levels of inflammatory cytokines in the follicular fluid significantly decreased in the treated group (p < 0.05). In patients in the treated group who underwent a second ova retrieval, the results were compared between those in the first ova retrieval (immediately after the end of treatment) and those in the second ova retrieval (four months after the first retrieval). The numbers of follicles following COH, retrieved, mature and fertilized ova were significantly increased in the second ova retrieval.

Salvage Human Leukocyte Antigen-Haploidentical Hematopoietic Cell Transplant With Posttransplant Cyclophosphamide for Graft Failure in a Patient With Chronic Active Epstein-Barr Virus Infection.

Salvage human leukocyte antigen-haploidentical hematopoietic cell transplant using posttransplant cyclophosphamide has shown promising results for graft failure in various hematological disorders. However, to our knowledge, no such findings have been reported for a case of chronic active Epstein-Barr virus infection, although graft failure is relatively common in patients with chronic active Epstein-Barr virus infection. We report a case of a 32-year-old woman with natural killer-cell type chronic active Epstein-Barr virus infection who experienced graft failure after a first allogeneic hematopoietic cell transplant from an unrelated human leukocyte antigen-matched donor.The patientreceived a second allogeneic hematopoietic cell transplant with human leukocyte antigen-haploidentical hematopoietic cell transplant using posttransplant cyclophosphamide (cyclophosphamide, 50 mg/kg, on day 3 and day 4) following reduced-intensity conditioning as rescue therapy. Neutrophils successfully engrafted on day 19, and the patient sustained remission without severe transplant-related complication 10 months after salvage human leukocyte antigen- haploidentical hematopoietic cell transplant using posttransplant cyclophosphamide. This report suggests that salvage human leukocyte antigen- haploidentical hematopoietic cell transplant using posttransplant cyclophosphamide may be a feasible therapeutic option for graft failure in patients with chronic active Epstein-Barr virus infection.

The Hematopoietic Effect of Ninjinyoeito (TJ-108), a Traditional Japanese Herbal Medicine, in Pregnant Women Preparing for Autologous Blood Storage.

Background and Objectives: There are no reports showing the hematopoietic effect of TJ-108 on pregnant women. The aim of this study was to investigate the effect of TJ-108 on the hemoglobin and hematocrit levels, and white blood cell and platelet counts of pregnant women complicated with placenta previa who were managed with autologous blood storage for cesarean section. Materials and Methods: We studied two groups of patients who were complicated with placenta previa and who underwent cesarean delivery. Group A consisted of women who were treated with oral iron medication (100 mg/day), and Group B consisted of women who were treated with TJ-108 at a dose of 9.0 g per day, in addition to oral iron medication, from the first day of blood storage until the day before cesarean delivery. To evaluate the effect of TJ-108, the patients' red blood cell (RBC); Hb; hematocrit (Ht); white blood cell (WBC); and platelet count (PLT) levels were measured 7 days after storage and at postoperative days (POD) 1 and 5. Results: The study included 65 individuals, 38 in group A and 27 in group B. At the initial storage, a 0.2 g/dL reduction in Hb levels was observed, as compared to the initial Hb levels, in the TJ-108 treated patients, whereas a 0.6 g/dL reduction in Hb levels was observed in the non-TJ-108 treated group. On the other hand, regarding the second and subsequent storages, no significant difference was found in the decrease in the Hb levels of both groups. Conclusions: This study is the first report showing the effect of TJ-108 on improving anemia in pregnant women, presumably by its boosting effect on myelohematopoiesis. Therefore, the combined administration of both iron and TJ-108 is effective as a strategy for pregnant women at a high risk of PPH due to complications such as placenta previa.

Preliminary Outcomes of Cervical Cerclage for Shortened Cervix with Decidual Polyp.

The aim of this study was to elucidate the nature of decidual polyp (DP) and to compare DP outcomes treated with cervical cerclage for a shortened cervix with the outcomes of cases treated with cervical cerclage without DP. The medical records of pregnant women who were complicated with cervical polyps were retrospectively reviewed. Cervical cerclage was considered for those cases with a shortened cervical length of under 25 mm and before 25 gestational weeks. We also reviewed pregnant women who had no cervical polyps, and who underwent cervical cerclage during the same study period, and defined them as the control group. A total of 56 pregnant women with cervical polyps were identified. All of the polyps in the 14 cases that had undergone cervical cerclage migrated into the cervical canal. Of the thirty seven cases with cervical polyps that did not necessitate cervical cerclage, eight women delivered preterm and six of these cases were diagnosed as DP. In all of the women studied, polyp migration was observed in 68.6 %. Cervical cerclage was performed significantly earlier in the DP group than in the control group of 46 cases (p < 0.001; 18.4 weeks vs. 21.4 weeks, respectively). Cervical cerclage is effective in DP cases with a shortened cervical length and polypectomy should not be performed during pregnancy because of the risk of miscarriage.

Long-term follow up in two cases of pelvic reconstruction using a combined VRAM flap-sacrocolpopexy for severe perineal hernia after abdominoperineal resection.

Perineal hernia is an infrequent complication of abdominoperineal resection (APR) and, currently, there is no consensus as to the optimal operative technique. Surgical repair can be achieved by either cerclage or the use of mesh or autologous tissue, and it has been reported that the recurrence rate after repair using autologous tissue is 33%. We present two post-APR cases of severe perineal hernia with pelvic organ prolapse (POP) which did not improve after repair using mesh. We regenerated the pelvic floor using a vertical rectus abdominis myocutaneous (VRAM) flap and performed a concomitant sacrocolpopexy to fix the POP. Drooping of the perineum and pelvic floor was greatly improved, and the patients have not experienced any recurrence for 6 years. This dual procedure has not been previously mentioned in the literature, and we consider this the first report of its kind.

Incarcerated Gravid Uterus: Spontaneous Resolution Is Not Rare.

AIM: Incarcerated gravid uterus is a rare obstetrical complication that leads to adverse outcomes, especially if the uterus remains incarcerated and the condition goes undiagnosed until delivery. However, there is no consensus regarding the optimal management of this complication because of its rarity. In this study, we aimed to elucidate the incidence of incarcerated gravid uterus, as well as its natural courses and perinatal outcomes. METHODS: We retrospectively reviewed medical records of patients who had incarcerated gravid uterus and managed at Osaka City University Hospital between April 2011 and March 2021. Incarcerated gravid uterus was defined as a retroverted or retroflexed uterus after 16 weeks of gestation. RESULTS: There were 14 incarcerated cases among 6958 pregnant women, and 13 of them had some kind of gynecological complication and/or history. Spontaneous resolution of incarcerated gravid uterus after 16 gestational weeks was observed in six cases before the late second trimester and five cases at the late second trimester to early third trimester. Three cases remained incarcerated at term or near-term. One case with adenomyosis had severe abdominal pain, although it was difficult to ascertain whether the cause of pain was triggered by adenomyosis and/or incarceration. One case was misdiagnosed as placenta previa, and the uterine cervix was subsequently injured during cesarean delivery, resulting in massive hemorrhaging. CONCLUSIONS: Approximately 1 in 2300 pregnancies continued to be in an incarcerated condition at term or near-term, and 78.5% of cases showed a spontaneous resolution after 16 weeks of gestation. Expectant management with careful attention to the incarcerated gravid uterus may be one option in situations where there are no severe symptoms related to the incarceration itself.

Preliminary evaluation of the short-term outcomes of polytetrafluoroethylene mesh for pelvic organ prolapse.

AIM: Tension-free vaginal mesh (TVM) surgery using synthetic polypropylene (PP) soft mesh had spread rapidly. However, the frequency of mesh-related postoperative complications had increased, and PP was banned in April 2019. In Japan, however, transvaginal surgery using polytetrafluoroethylene (PTFE) mesh had been approved. In this study, we evaluated the clinical outcome and quality of life (QOL) of the postoperative course using PP mesh and PTFE mesh (named "ORIHIME™" ) in a combination surgery for utero-sacral ligament suspension and anterior vaginal support using anterior TVM. METHODS: The vaginal hysterectomy and utero-sacral ligament colpopexy augmented by anterior vaginal mesh implants using PP mesh and PTFE mesh were performed on patients with stage III to IV cystocele and uterine prolapse. The clinical outcome and QOL changes in their postoperative course were evaluated by comparing 15 cases of PP mesh and 13 cases of PTFE mesh. RESULTS: There was no difference between the PP group and PTFE group in characteristics. No mesh-related complications occurred during the follow-up period. With regard to the pelvic organ prolapse quantification (POP-Q) score, no significant difference was found between the two groups. Comparing the postoperative QOL of both groups, the PTFE group had significantly higher values in two domains than PP group (SF-12v2 questionnaire). CONCLUSIONS: We used the world's first PTFE mesh to compare PP mesh with postoperative POP-Q and QOL after the same surgery, with the same operator, and at the same institution. The results showed no significant difference between both mesh materials in the short-term.

Transvaginal polytetrafluoroethylene mesh surgery for pelvic organ prolapse: 1-year clinical outcomes.

OBJECTIVES: To evaluate the safety and efficacy of transvaginal mesh surgery using a polytetrafluoroethylene mesh to treat pelvic organ prolapse. METHODS: This prospective observational study included women undergoing transvaginal mesh surgery for pelvic organ prolapse that used new polytetrafluoroethylene mesh cut into a shape similar to that of Elevate. We evaluated the subjective and objective outcomes at 3 and 12 months, as well as postoperative complication rates. RESULTS: This study included 55 patients. The pelvic organ prolapse quantification scores improved significantly at 3 and 12 months after surgery compared with scores before surgery. In four patients (7.3%), a pelvic examination showed stage 2 objective recurrence without subjective symptoms. Clavien-Dindo grades 2 and 3 perioperative complications were observed in 9.1% and 1.8% of the patients, respectively. Vaginal mesh exposure occurred in one patient (1.8%) at the time of the 3-month follow-up evaluation. The mesh was exposed at the proximal midline of the anterior vaginal wall. CONCLUSIONS: These findings show the safe and effective use of the polytetrafluoroethylene mesh for transvaginal mesh surgery.

Diabetic pregnancy activates the innate immune response through TLR5 or TLR1/2 on neonatal monocyte.

Diabetes mellitus (DM) during pregnancy causes congenital malformation, macrosomia, respiratory distress syndrome, and other abnormalities in neonates, but whether maternal DM affects the neonatal innate immune system is unknown. Therefore we aimed to reveal the influence of DM in pregnancy on the toll-like receptor (TLR)-mediated innate immune response in neonates. Cord blood was collected after full-term vaginal or cesarean delivery and classified into a DM group (n=8) and non-DM (control) group (n=7). Mononuclear cells were harvested from cord blood by using density gradient centrifugation, after which anti-CD14 magnetic beads were used to isolate monocytes from the mononuclear population. After monocytes were cultured with lipopolysaccharide (TLR4 ligand), flagellin (TLR5 ligand), Pam3CSK4 (TLR1/TLR2 ligand), zymosan (TLR2/TLR6 ligand), or macrophage-activating lipopeptide (TLR2/TLR6 ligand) for 12h, the cytokine levels (interleukin [IL]-8, IL-6, IL-1ß, IL-10, tumor necrosis factor alpha and IL-12) in the culture supernatants were measured. Compared with the control group, the DM group had higher concentrations of IL-8 (P=0.01) and tumor necrosis factor alpha (P=0.02) after monocyte cultures were stimulated with Pam3CSK4 and higher concentrations of IL-8 (P=0.01) after flagellin treatment. In contrast, stimulation with lipopolysaccharide, zymosan, or macrophage-activating lipopeptide did not lead to any difference in cytokine profiles between the two groups. These data indicate that maternal DM induces excessive inflammatory activation in neonates via a TLR5- or TLR1/2-mediated innate immune response.

Gene-modified embryonic stem cell test to characterize chemical risks.

A high-throughput test of cell growth inhibition was performed using mouse embryonic stem (ES) cells to assess chemical toxicities. We herein demonstrated using a 96-well culture plate approach and the MTT assay that this method was suitable for prioritization of chemicals for their cytotoxic properties. In order to categorize chemicals, we used p53 gene-modified mouse ES cells as well as wild-type ES cells. The p53 gene is a well-known tumor suppressor and controls programmed cell death (apoptosis) and cellular senescence that is triggered by DNA-damaging agents such as alkylating agents and radiation. In the present study, p53-deficient ES cells were found to be more resistant to a tumor initiator, diethylnitrosamine (DEN), than wild-type ES cells, suggesting the inhibition of apoptosis or senescence by a dysfunction in p53. Chromosome aberrations were more frequently detected in p53-deficient ES cells than in wild-type cells, indicating genomic instability due to the deletion of p53. Other tumor initiators, methyl methanesulfonate (MMS) and N-methyl-N-nitrosourea (NMU), did not reveal apparent differences in cytotoxicity between wild-type and p53-deficient ES cells. Thus, ES test system using gene-modified ES cells may be used to categorize chemicals by detecting their characteristic effects on apoptosis, genotoxic potentials as well as general cytotoxicity.

Zymosan Induces Immune Responses Comparable with Those of Adults in Monocytes, Dendritic Cells, and Monocyte-Derived Dendritic Cells from Cord Blood.

OBJECTIVE: To investigate the differences in toll-like receptor (TLR)-mediated immune responses between human neonates and adults, focusing on the cytokine profiles of monocytes, dendritic cells (DCs), and monocyte-derived DCs (MoDCs) in cord and adult blood. STUDY DESIGN: Purified monocytes, DCs, and MoDCs were stimulated with the following TLR ligands: lipopolysaccharide (TLR4), Pam3CSK4 (TLR1/2), flagellin (TLR5), zymosan (TLR2), polyinosinic:polycytidylic acid (TLR3), imiquimod (TLR7), and CpG (TLR9). Interleukin (IL)-8, IL-6, tumor necrosis factor, IL-1ß, and IL-10 concentrations were analyzed in culture supernatants. RESULTS: Compared with the effects in adult blood, lipopolysaccharide-, Pam3CSK4-, flagellin-, and polyinosinic:polycytidylic acid-stimulated inflammatory cytokine production in cord blood was generally weak in monocytes, comparable in DCs, and elevated in MoDCs. CpG- and imiquimod-stimulated cytokine production in DCs was comparable in cord blood and adult blood, but cytokine production was almost absent in monocytes and MoDCs in both cord blood and adult blood. In contrast, zymosan stimulation produced comparable inflammatory cytokine profiles in the monocytes, DCs, and MoDCs of cord blood and adult blood. CONCLUSION: The immaturity of TLR-mediated innate immunity in neonates depends on monocytes rather than on DCs. Our results indicate that zymosan-mediated TLR2 signaling may be useful for developing a neonatal vaccine adjuvant.

Successful management of pregnancy with very-long-chain acyl-coenzyme A dehydrogenase deficiency.

Very-long-chain acyl-coenzyme A dehydrogenase deficiency (VLCADD) is a rare and life-threatening disease characterized by an enzymatic defect in the fatty acid ß-oxidation pathway. A nulliparous woman with VLCADD showed improvements in serum levels of the long-chain acylcarnitine moiety (C14:1) during pregnancy and successfully delivered a healthy infant vaginally. Pregnancy and vaginal delivery can be successfully completed in patients with VLCADD with careful management.
