Objectives We aimed to clarify the accuracy of pregnant women’s knowledge and understanding regarding infectious disease screening in early pregnancy and clarify the roles that should be played by health care providers in promoting the health of pregnant women and their children. Methods A cross-sectional questionnaire survey was conducted in 25 hospitals across Japan from May 2018 to September 2019. We compared the agreement rates regarding screening results for hepatitis B virus (HBV), hepatitis C virus (HCV), syphilis, human T-cell leukemia virus-1 (HTLV-1), and cervical cytology in the medical records and understanding of their results by pregnant women. We then investigated whether participants had knowledge regarding the risk of mother-to child transmission in these diseases and factors associated with their knowledge. Results We enrolled 2,838 respondents in this study. The rates of agreement for HBV and cervical cancer screening related to human papillomavirus infection were “substantial,” those for syphilis was “moderate,” and those for HCV and HTLV-1 were “fair,” according to the Kappa coefficient. The rate of knowledge regarding mother-to-child transmission of syphilis was highest (37.0%); this rate for the other items was approximately 30%. Increased knowledge was associated with higher educational level and higher annual income. Conclusions for Practice Pregnant women in Japan had generally good levels of understanding regarding their results in early-pregnancy infectious disease screening. However, they had insufficient knowledge regarding mother-to-child transmission of these diseases. Health care providers should raise awareness in infectious disease prevention among pregnant women and the general public, providing appropriate measures and implementing effective perinatal checkups and follow-ups for infectious diseases.

Cervical varix during pregnancy is a rare condition, and standard management for bleeding from a varix has not been established. We performed cross double cervical cerclage and effectively stopped bleeding. A 41-year-old female had a twin pregnancy. The development of a cervical varix was observed during pregnancy and bleeding from ruptured varix started at 20 weeks of gestation. We performed surgical hemostasis by cervical cerclage. In the first cerclage, we could not stop the bleeding from the varix. For further restriction of blood supply to the cervical varix, we performed a second cerclage in a crossed position on a deeper side of the vagina than the first cerclage. Then the bleeding completely stopped and there was no bleeding until delivery. The “cross double McDonald cerclage” performed in our patient may be a useful modified cerclage method for stopping intractable bleeding from the cervix during pregnancy.

A 37-year-old pregnant woman who had undergone three previous cesarean sections was diagnosed as having placenta percreta. We decided to perform cesarean hysterectomy with bilateral common iliac artery balloon occlusion (CIABO). The duration of surgery was 2 h and 2 min and total estimated blood loss was 2600 mL. Surgery was completed without any surgical complications, but the pulse oximeter waveform of the left leg became undetectable during surgery. We immediately performed angiography after closure of laparotomy and found abnormal pooling of contrast media at the left common iliac artery in the region in which the balloon was positioned. We made a diagnosis of left common iliac artery dissection caused by CIABO. We performed emergent revascularization by intravascular stenting. We conclude that CIABO can cause common iliac artery dissection by mechanical stimulation of the inflated balloon. Careful intraoperative evaluation of limb ischemia and preparation of intravascular treatment is needed for a safe procedure.

Intrauterine infection is one of the most important causes of maternal death. In perinatal emergency, we often miss an opportunity to obtain culture specimens. In this study, we tried to examine whether we investigated whether bacteria causing infection can be detected from a formalin-fixed paraffin-embedded (FFPE) placental specimen. We examined the placenta from a maternal invasive infection that resulted in infectious abortion at 18 weeks of gestation. The case was diagnosed by acute fever and abdominal pain, and the patient was cured after 3 weeks of intensive antimicrobial treatment. Four Streptococcus pyogenes strains were isolated from vaginal fluid and blood cultures of the patient. All of the strain types were emm1/ST28. We amplified the V1–V2 region of 16S rRNA from an FFPE placental specimen and sequencing was performed using a next-generation sequencer (NGS). Taxonomic analysis was then performed for sequenced data. We succeeded in detecting causative pathogens from the FFPE placenta: 69.1% of the predominantly identified bacteria were S. pyogenes and other small populations of bacteria were detected. Our results revealed the utility of NGS for 16S rRNA analysis of an FFPE placenta. This method may reveal previous perinatal invasive infections of unknown origin retrospectively.

Aim Radical trachelectomy (RT) with pelvic lymphadenectomy has become an option for young patients with early invasive uterine cervical cancer who decide to maintain their fertility. However, this operative method entails a high risk for the following pregnancy due to its radicality. Therefore, RT for pregnant patients can be a challenge both for gynecologic oncologists and obstetricians. Methods We have performed vaginal RT for five pregnant patients with uterine cervical cancer stage 1B1 according to the method of Dargent et al. The operations were performed between 16 and 26 weeks of pregnancy, and the patients were followed up carefully according to the follow-up methods we reported previously. Results Vaginal RT was performed for five patients without any troubles. Four of the patients continued their pregnancies until almost 34 weeks or longer under our previously published follow-up schedule. The pregnancy of one patient was terminated at 26 weeks due to recurrence of the cancer. Conclusion Expansion of vaginal RT for pregnant patients with uterine cervical cancer could be a practical option for pregnant patients with early invasive uterine cervical cancer.

Preeclampsia (PE) is related to an imbalance of angiogenic factors. Placental growth factor (PlGF) is reduced in early onset PE. Recent evidence indicates that metformin and statins may suppress endoplasmic reticulum (ER) stress. We previously reported that the unfolded protein response activated by ER stress down-regulated PlGF protein expression and predicted these drugs could prevent placental ER stress and up-regulate PlGF protein expression in trophoblast-like cells. In this study, we aimed to establish the effects of these drugs on PlGF and activating transcription factor 4 (ATF4) protein expression. We confirmed that PlGF messenger RNA (mRNA) levels were decreased under ER stress induced by thapsigargin and that ATF4 mRNA was increased under the same conditions and then administered metformin to it. Transcript analysis showed increased PlGF mRNA compared with thapsigargin only treatment and that this was dependent on metformin levels. Under ER stress, western blot showed high levels of ATF4 and phosphorylated-eukaryotic initiation factor 2 subunit α (p-eIF2α) but low levels of PlGF protein. By contrast, compared with thapsigargin alone, ATF4 and p-eIF2α levels were low and PlGF levels were high when metformin and thapsigargin were given, but these were again dependent on metformin concentrations. Western blot also confirmed that pravastatin attenuated ER stress and increased PlGF protein expression. In conclusion, metformin and pravastatin suppressed ER stress and restored PlGF levels in trophoblast-like cells. However, although these results indicate that these drugs have a potential for preventing or treating PE, the lack of clarity on the mechanism requires further study.

Purpose Radical trachelectomy (RT) with pelvic lymphadenectomy has become a new treatment option for young patients with uterine cervical cancer stages 1A2–1B1 who desire the preservation of their fertility. However, the application of RT for pregnant patients is still controversial. We comparatively studied both obstetrical and oncological outcomes of pregnant patients who underwent vaginal RT during pregnancy and those who underwent vaginal RT before pregnancy. Methods Both obstetrical and oncological results of eight patients who underwent vaginal RT with pelvic lymphadenectomy during pregnancy in our institute between 2010 and 2020 (Group A), and ten pregnant patients who underwent vaginal RT with pelvic lymphadenectomy before pregnancy during the same period (Group B) were reviewed based on their medical charts. Results There were no significant differences in blood loss, surgical time, or surgical completeness between Group A and Group B. Nor were there significant differences in obstetrical outcomes between the two groups. However, two of the eight patients in Group A had recurrence of the cancer. None of the patients in Group B has shown any signs of recurrence thus far. Conclusion Vaginal RT during pregnancy does not affect the obstetrical prognoses of patients with early invasive uterine cervical cancer, and it might be a tolerable treatment modality for them. However, oncologically, it should be performed carefully as there is a risk of recurrence.

Cervical insufficiency (CI) with concomitant intrauterine adhesions (IUAs) is a common clinical phenomenon among CI patients. But there are neither published reports regarding the difference in diagnosis and treatment of such patients compared to those with CI only, nor any report about their prognosis. This study aimed to preliminary the alteration in diagnostic and curative aspects of these patients, so as to provide a certain reference for the clinical management of such conditions.Ten patients with CI combined with moderate to severe IUAs were diagnosed, treated and followed up at the Third Xiangya Hospital of Central South University from September 2017 to August 2019, their medical records and the pregnancy outcomes were retrospectively analyzed.All 10 patients had a previous history of typical painless cervical dilatation during the second trimester. All patients were moderate to severer IUAs, and the mean AFS score of IUAs was 9.80±1.08 (range, 8 to 12). Preoperatively, in 6 patients, the No. 7 Hegar dilator was able to pass through the internal cervical os before surgery without resistance. In the other 4 patients, the Hegar dilator could not be inserted before surgery due to the adhesions of the cervical canal and the lower uterine segment; the diagnoses of these patients were further confirmed at 3 months after hysteroscopic adhesiolysis (HA) when the No. 7 Hegar dilator was able to pass through the internal cervical os without resistance. There were 9 patients underwent pre-pregnancy laparoscopic cervical cerclage after HA. The remaining 1 patient exceptionally underwent laparoscopic cervical cerclage prior to HA, as the cervix was too loose to retain and be treated with an intrauterine device (IUD) or distended Foley's catheter balloon; which essentially prevent postoperative adhesion reformation. The patients were followed-up for 3 months to 2 years. The pregnancy rate was 60%, and the live birth rate was 100%.In patients with CI and concomitant cervical or lower uterine segment IUAs, it is necessary to separate the adhesion prior to evaluating the cervical competency with the No. 7 Hegar dilator, to confirm the diagnosis. However, when the cervix is too loose, laparoscopic cervical cerclage is exceptionally carried out first and then IUAs is treated. Pre-pregnancy laparoscopic cervical cerclage has a good prognosis in patients with CI complicated by moderate to severe IUAs.

Background Radical tracheletomy (RT) with pelvic lymphadenectomy has become an option for young patients with early invasive uterine cervical cancer who desire to maintain their fertility. However, this operative method entails a high risk for the following pregnancy due to its radicality. Methods We have performed vaginal RT for 71 patients and have experienced 28 pregnancies in 21 patients. They were followed up carefully according to the follow-up methods we reported previously. Their pregnancy courses and prognoses after the pregnancy were retrospectively reviewed. Results All the vaginal RTs were performed safely without serious complications, including 6 patients who underwent the operation during pregnancy. The median time to be pregnant after RT was 29.5 months. 13 patients (46%) became pregnant without artificial insemination by husband or assisted reproductive technology. Cesarean section was performed for all of them. The median time of pregnancy was 34 weeks, and emergent cesarean section was performed for 7 pregnancies (25%). The median birth weight was 2156 g. Four patients had trouble with cervical cerclage, and they suffered from sudden premature preterm rupture of the membrane (pPROM) during the second trimester of pregnancy. We underwent transabdominal cerclage (TAC) for all of them and careful management for the prevention of uterine infection was performed. One patient had a recurrence of cancer during pregnancy. Conclusions Both the obstetrical prognosis and oncological prognosis after vaginal RT have become favorable for pregnant patients after vaginal RT.

Objective: Hereditary antithrombin (AT) deficiency increases the risk of venous thromboembolism (VTE) in pregnant woman. We report the first case of administration of recombinant human antithrombin (rhAT) to a pregnant Japanese woman with AT deficiency. Case report: A 30-year-old woman, gravida 2 para 0, was referred to our hospital because of AT deficiency. Unfractionated heparin was administered from 13 weeks of gestation and rhAT was administered from labor onset. A cesarean section was performed and the patient and her baby were healthy, with no sequelae. Conclusion: We concluded that rhAT was effective for preventing VTE during delivery, with no potential infection risks.

Aim Patients with an ultra-short uterine cervix as a result of large conization, repeated conization or radical trachelectomy (RT), are at high risk of preterm premature rupture of the membrane, which leads to preterm birth. We have commenced performing transabdominal cerclage (TAC) of the uterine cervix for these patients. In this study, we examined the safety of TAC and its impact on pregnancy. Methods We have performed TAC in 11 patients before pregnancy: in six after large cervical operations, such as repeated conization; and in five for difficulties with cervical cerclage after RT. After laparotomy, a Teflon thread was placed in the avascular space between the uterine vessels and the uterine muscle, and tied. The clinical course of the patients after TAC and their pregnancy course were retrospectively reviewed. Results TAC was performed safely without any complications. The mean operative duration was 53 ± 10 min, and the mean blood loss during the operation was 49 ± 64 mL. Seven women conceived within 2 years after TAC. Their pregnancy courses were favorable. Five of the women underwent scheduled cesarean sections, while two pregnancies are ongoing. Conclusions Although there are risks of various complications as a result of the use of non-absorbable thread and the need for two extra laparotomies, TAC can be a safe and useful option for patients who show cervical incompetence after large uterine cervical operations, such as RT or large conization.

ObjectiveTo determine whether an educational leaflet had any effect on seat belt use, seat preference and motor vehicle accidents rate during pregnancy in Japan.DesignProspective, non-randomised control trial with a questionnaire survey.SettingEight obstetric hospitals in Sapporo, Japan.Participants2216 pregnant women, of whom 1105 received the leaflet (intervention group) and 1111 did not (control group).InterventionsDistribution of an educational leaflet on seat belt use to women in the intervention group.Primary outcome measuresThe effect of an educational leaflet on seat belt use, each pregnant woman’s seat preference and the women’s rates of motor vehicle accidents rate during their pregnancies. To evaluate the effects, the intervention group’s responses to the questionnaires were compared with those of the control group.ResultsThe proportion of subjects who always used seat belts during pregnancy was significantly higher in the intervention group (91.3%) than in the control group (86.7%; p=0.0005). Among all subjects, the percentage of women who preferred the driver’s seat was lower during pregnancy (27.0%) than before pregnancy (38.7%), and the percentage of women who preferred the rear seat was higher during pregnancy (28.8%) than before pregnancy (21.0%). These two rates did not differ between two groups. Seventy-one women (3.2%) reported experiencing a motor vehicle accident during pregnancy. The motor vehicle accident rate for the intervention group (3.3%) was similar to that for the control group (3.2%).ConclusionsAn educational seat belt leaflet was effective in raising the rate of consistent seat belt use during pregnancy, but it did not decrease the rate of motor vehicle accidents. The wearing of seat belts should be promoted more extensively among pregnant women to decrease rates of pregnancy-related morbidity and mortality from motor vehicle accidents.

Twin pregnancy after radical trachelectomy (RT) for uterine cervical cancer involves an extremely high risk of preterm premature rupture of the membrane (pPROM) and the following occurrence of preterm birth. Herein we report the first case of twin pregnancy after vaginal RT in a Japanese woman. The patient was a 36-year-old nulliparous woman. She became pregnant with twins one year after vaginal RT with laparoscopic lymphadenectomy and the following treatment with the use of in vitro fertilization/embryo transfer. Her pregnancy course was favorable with vaginal disinfection, bed rest, and administration of progesterone, ritodrine, and an ulinastatin vaginal suppository. At 31 weeks + 4 days of pregnancy, a scheduled cesarean section was performed. One baby weighed 1000g, with Apgar scores of 7/8, and the other 1100g, with Apgar scores of 8/9. Her postpartum course was also favorable. The mother remains without evidence of recurrence of the cancer at the time of this report.

Aim Radical trachelectomy (RT) with lymphadenectomy has become a standard treatment modality for patients with early invasive uterine cervical cancer who hope to preserve fertility. However, pregnancy after RT has high risks of preterm birth. The possibility of more conservative RT and the application of RT for patients with higher clinical stages were studied. Methods The medical charts and specimens of 42 patients who underwent RT and 64 patients who underwent radical hysterectomy were retrospectively studied. Tumor size, distance between the margin of the cancer and the internal orifice of the uterus (os), parametrial invasion, lymph node metastasis and prognoses were investigated. Results The average distances between the inner margin of the cancer and the internal os were 37 mm, 29 mm, 18.7 mm and 14 mm for patients with stage 1 A2, 1B1 (≤ 2 cm), 1B1 (> 2 cm) and 1B2, respectively. When amputation was performed 10 mm below the internal os, all 10 patients with 1 A2, 57 with 1B1 (≤ 2 cm), 19 with 1B1 (> 2 cm), and one with 1B2 had a cancer-free margin > 10 mm. Patients with stage 1 A2 had a cancer-free margin > 10 mm even if we amputated the cervix 20 mm below the internal os. Parametrial invasion was detected in two patients with stage 1B1. Conclusions A simple trachelectomy 20 mm below the internal os with pelvic lymphadenectomy might be possible for stage 1 A2 patients. The present method is best for stage 1B1 patients (≤ 2 cm). RT for stage 1B1 (>2 cm) or higher stages should be contraindicated.

Uterine cervical conization is related to adverse pregnancy outcomes in subsequent pregnancies. To deal with this problem, we started conservative coin-shaped conization for reproductive-aged patients with cervical intraepithelial neoplasia (CIN). Here we report both the obstetrical and oncological impacts of this operation in comparison with the standard cone-shaped resection. A total of 401 women 44 years old or younger were treated in our hospital by CO2 laser conization between 2003 and 2012, and subsequently 50 patients became pregnant. The patients were divided into two groups, a standard cone-shaped conization group (until 2008) and a shallow coin-shaped conization group (beginning in 2008). The pregnancy courses and oncological prognoses of these two groups were studied. Cone height reduction of about 3 mm was done. However, there were no significant differences between the two groups with regard to the occurrence of oncological complications. In the standard conization group, 18 of the 25 patients delivered at term. In the coin-shaped conization group, 20 of the 25 patients delivered at term. There were no significant differences between the two groups with regard to the occurrence of various obstetrical complications. However, the reduction rate of cervical length over the pregnancy was smaller in the coin-shaped group and the number of patients with a short cervix length of 2 cm or less was smaller in the coin-shaped group. Although conservative coin-shaped conization did not markedly improve the obstetrical prognosis, this operative procedure improved the reduction rate of uterine cervical length over the pregnancy without any increase in oncological complications.

Fukushima Daiichi nuclear power plants (1F) were damaged by unprecedented severe accident in the Great East Japan Earthquake on 11 March 2011, and seawater has been injected as an emergency countermeasure for the core cooling. Although, the RPV and PCV were not supposed to be exposed to diluted seawater, they have been exposed to diluted seawater environment or high-moisture environment. Therefore, seawater corrosion has become an important issue. Immersion corrosion tests were performed for low-alloy steel of RPV material and carbon steel of PCV material in 1F cooling-water-simulated environment. As a result, the mass loss by corrosion was reduced with the decreasing temperature and chloride ion concentration. Moreover, the effects of nitrogen deaeration and Na2WO4 addition on corrosion protection were remarkable among the selected corrosion countermeasures. In addition, the integrity assessments of RPV and PCV were performed considering the reduction of plate thickness based on corrosion test data and t...

Bone marrow-derived mesenchymal stem cells (BM-MSC) has been applied as the most valuable source of autologous cell transplantation for various diseases including diabetic complications. However, hyperglycemia may cause abnormalities in intrinsic BM-MSC which might lose sufficient therapeutic effects in diabetic patients. We demonstrated the functional abnormalities in BM-MSC derived from both type 1 and type 2 diabetes models in vitro, which resulted in loss of therapeutic effects in vivo in diabetic nephropathy (DN). Then, we developed a novel method to improve abnormalities in BM-MSC using human umbilical cord extracts, namely Wharton’s jelly extract supernatant (WJs). WJs is a cocktail of growth factors, extracellular matrixes and exosomes, which ameliorates proliferative capacity, motility, mitochondrial degeneration, endoplasmic reticular functions and exosome secretions in both type 1 and type 2 diabetes-derived BM-MSC (DM-MSC). Exosomes contained in WJs were a key factor for this activation, which exerted similar effects to complete WJs. DM-MSC activated by WJs ameliorated renal injury in both type 1 and type 2 DN. In this study, we developed a novel activating method using WJs to significantly increase the therapeutic effect of BM-MSC, which may allow effective autologous cell transplantation.

We have performed 26 vaginal radical trachelectomies (RTs) for patients with early invasive uterine cervical cancer since 2003 and, to date, have experienced 8 deliveries. The procedure has a high risk for preterm labor and the subsequent occurrence of preterm premature rupture of membranes (pPROM). We report the present situation and the limits of follow-up of pregnancy after vaginal RT. Our operative procedure is based on that of Dargent et al. We usually amputate the cervix approximately 10 mm below the isthmus. To remove the parametrium, we cut at the level of type II hysterectomy. Pregnancy courses after vaginal RT were studied in 8 patients with respect to symptoms, cervical length, and several infectious signs. We recommended that patients enter hospital early in their second trimester, and prophylactic daily vaginal disinfection with povidone-iodine and an ulinastatin vaginal suppository were administered. Careful checking for vaginal infectious signs, as well as cervical length and abdominal tension of patients was also performed. Four patients followed up with this modality were able to continue their pregnancies until late in the third trimester. However, this follow-up modality was not effective for patients who showed cervical incompetence due to slack cervical cerclage. They suffered from pPROM at 26 and 19 weeks of gestation. We need a new approach for the management of pregnant patients after vaginal RT with cervical incompetence due to slack cervical cerclage to prevent cervical infection.

Placental adherence is one of the most common causes of emergency hysterectomy to save the mother’s life. Risk factors for placental adherence reportedly include a prior caesarean section, other previous uterine surgery, maternal age and multiparity. Recently, in vitro fertilization (IVF) pregnancy was also reported to be a risk factor [1]. Unfortunately, it appears likely that patients who seek help to have a baby are complicated with multiple risk factors. Physicians should be very careful when treating these patients. In the absence of serious symptoms, however, conservative therapy that preserves the patient’s fertility is preferable, so it has been proposed that conservative management should be attempted [2] unless the patient has massive bleeding [3] or signs of severe infection [4]. That said, there are few choices for conservative treatment. These include methotrexate (MTX) administration, uterine artery embolization (UAE) and uteruspreserving surgery [5, 6]. UAE is reported to be sometimes harmful to fertility [7], and it is usually difficult to continue MTX treatment when massive bleeding occurs during the therapy. As a backup treatment, uterus-preserving surgery [5] is thought to support the continuation of MTX treatment in these types of cases and should be tried if possible.

Aim: MicroRNA-34a (miR-34a) is associated with invasion and metastasis of various cancers. The trophoblastic cells of placenta accreta invade into the myometrium in a similar way to the invasion of cancers. We studied the roles of miR-34a in the pathogenesis of placenta accreta. Methods: The human choriocarcinoma cell line JAR was used for in vitro experiments as a model of trophoblasts, and placental tissues from the operative specimen of patients with or without placenta accreta were used for experiments in vivo. Morpholino antisense oligomer against miR-34a (miR-34a Morpho/AS) was added to JAR, and the expression of miR-34a and plasminogen activator inhibitor-1 (PAI-1) was determined by real time PCR. The effects of antisense, interleukin (IL)-6 and IL-8 in the process of invasion were studied with an invasion assay. Expression of miR-34a in vivo was studied with the use of fluorescent in situ hybridization (FISH). Results: Expression of miR-34a was inhibited by 65% with the administration of antisense, and a slight increase in miR-34a expression was observed with the addition of IL-6 and IL-8. PAI-1 expression decreased with the addition of IL-6 and IL-8, and increased with the administration of antisense. There was an increase in invasive capacity through the inhibition of miR-34a expression. Strong FISH expression of miR-34a was observed in trophoblast cells of non-placenta accreta, and a clear decrease in miR-34a expression was observed in those of placenta accreta. Conclusions: Expression of miR-34a was downregulated in placenta accreta. In vitro experiments also showed that the invasive potential of JAR increased by suppressing miR-34a, probably through the expression of PAI-1.

A 33 years old woman was referred to our hospital since her sixth pregnancy had been revealed. In fact, at 19 years of age she had diagnosed as having systemic lupus erythematosus without organ failure. In addition, she had a past history of uncontrollable severe pregnancy-induced hypertension occurred during the second pregnancy, resulting in extremely premature delivery and following postpartum HELLP syndrome. It was so severe that we employed administration of dexamethasone and plasma exchange to ameliorate a life-threatening situation. In the course of her recovery it was revealed that she had been complicated with antiphospholipid antibodies, and at the same time we observed that phosphatidylserine-dependent anti-prothrombin antibody IgG levels were declining as her condition was getting better. There-after, she became pregnant three times, but all pregnancies ended in miscarriage despite administration of prednisolone and anticoagulant therapy. Therefore, we realized that her recurrent miscarriages could not be prevented with generally acceptable therapies, so we tried intravenous immunoglobulin shortly after fetal heart beats were detected. In fact, her sixth pregnancy was going well, but we had to terminate it at the 35th week of gestation due to the onset of HELLP syndrome-like condition. However, she could achieve an almost intact pregnancy outcome without neonatal complications or persistently worsening postpartum HELLP syndrome-like condition. Considering the etiologic relation overlapping between systemic lupus erythematosus, antiphospholipid syndrome and recurrent miscarriage, intravenous immunoglobulin can be one of the treatment options for severe secondary recurrent miscarriage, although the evidence of the treatment is always certain. In addition, a decline of phosphatidylserine-dependent anti-prothrombin antibody IgG levels we observed in this case may represent its therapeutic immunomodulatory effects.

Background and study aims In many patients, percutaneous endoscopic gastrostomy (PEG) can be limited by digestive tract stenosis. PEG placement using an introducer is the safest alternative for this group of patients, but the available devices are difficult to implement and require smaller-caliber tubes. The aim of this study was to evaluate the modification of an introducer technique device for PEG placement with regard to the following: procedure feasibility, possibility of using a 20-Fr balloon gastrostomy tube, tube-related function and problems, complications, procedure safety, and mortality. Patients and methods Between March 2007 and February 2008, 30 consecutive patients with head and neck malignancies underwent introducer PEG placement with the modified device and gastropexy. Each patient was evaluated for 60 days after the procedure for the success of the procedure, infection, pain, complications, mortality, and problems with the procedure. Results The procedure was successful in all cases with no perioperative complications. No signs of stomal infection were observed using the combined infection score. The majority of patients experienced mild-to-moderate pain both in the immediate postoperative period and at 72 hours. One major early complication (3.3%) and two minor complications (6.7%) were observed. No procedure-related deaths occurred during the first 60 days after the procedure. Conclusion The device modification for PEG using the introducer technique is feasible, safe, and efficient in outpatients with obstructive head and neck cancer. In this series, it allowed the use of a larger-caliber tube with low complication rates and no procedure-related mortality.

A diagnosis of cervical cancer during pregnancy poses difficult management and ethical problems. Survival of the patient is the foremost concern, but fetal viability and well-being must also be addressed. Radical trachelectomy (RT) has recently begun to be performed as a possible treatment modality for early stage invasive uterine cervical cancer in pregnant patients who would like to continue their pregnancy. A 32-year-old Japanese woman visited a local hospital for prenatal care, and was diagnosed with a FIGO I B1 adenocarcinoma of the uterine cervix. She had a strong desire to avoid pregnancy termination, so she was admitted to our hospital for fertility-preserving surgery. After extensive counseling, vaginal radical trachelectomy with abdominal pelvic lymphadenectomy was performed in the 16th gestational week. The excised uterine cervix and lymph nodes were pathologically negative for cancer. To maintain her pregnancy, daily vaginal disinfection with povidone iodine, bed rest, and administration of ritodrine and an ulinastatin vaginal suppository were continued until the delivery. At 34 weeks' gestation, an emergency cesarean section was performed because of sudden premature rupture of the membranes. A baby girl was born weighing 2112 g, with Apgar score of 8/9. The mother remains without evidence of recurrence at the time of this report. This is the first case of successful pregnancy and delivery in Japan after vaginal RT.

Background. Vaginal radical trachectomy (RT) ligates and cuts several arteries supplying the uterus. Changes of blood supply to the uterus in two patients who experienced pregnancy and delivery were studied by using 3-D CT scanning. Effects of changes of blood supply to the uterus on the pregnancy courses were also examined. Methods. Vascular distribution in the uterus was studied in two patients who received vaginal RT after delivery. Effects of changes of vascular distribution after vaginal RT were studied with respect to pregnancy courses and cervical functions. Results. New arterial vascularization from the ascending branches of uterine arteries or other arteries occurred, and these new vessels seemed to supply blood to the remaining cervix. Differences of fetal growth and histopathological changes in the placenta between the two patients could not be detected. Conclusion. Ligation and cutting of several supplying arteries by RT induces new areterial vascularization and it does not seem to affect fetal growth and placental function.

Pregnancy with invasive gynecologic cancer is a rare condition. It is still unclear whether we can choose planned delay in treatment until maturation of the fetus as a treatment modality for this condition. If there are no adverse effects from the cancer and there is improvement of neonatal outcomes, this treatment modality might be an option for patients with this condition.Eight pregnant patients were diagnosed as having invasive gynecologic cancer between January 1998 and December 2007. Five of them, (four with invasive uterine cervical cancer and one with ovarian cancer) chose planned delay in treatment. The pregnancy courses and prognoses of these patients were studied.The period of planned delay in treatment varied from 2 weeks to 19 weeks. The period was shorter for patients who had complications. The pain caused by the cancer was the main obstacle to this treatment modality in two patients (one with advanced ovarian cancer and one with uterine cervical cancer). No apparent tumor growth, elevation of tumor markers, or complications induced by the cancer itself were detected in the remaining three patients. Only the patient with advanced ovarian cancer died of the primary disease after the delivery. Fetal outcome was uniformly good for the delayed-treatment group. All the babies are growing well, and no fetal deaths or neonatal deaths occurred.Planned delay in treatment to allow for fetal maturity is acceptable in pregnant patients with certain types of invasive gynecologic cancers.
