Frequency of cul-de-sac obliteration in surgery for pelvic organ prolapse: a retrospective analysis.

INTRODUCTION AND HYPOTHESIS: We aimed to clarify the frequency of cul-de-sac obliteration in patients undergoing POP surgery. METHODS: We retrospectively reviewed patients who underwent laparoscopic POP surgery at our hospital between April 2017 and September 2021. RESULTS: In total, 191 cases were included in the analysis. Ten patients (5.2%) had cul-de-sac obliteration. No difference in age (73 years vs. 72 years, P = 0.99), parity (2 vs. 2, P = 0.64), or body mass index (BMI) (25.7 kg/m2 vs. 24.7 kg/m2, P = 0.34) was observed between the cul-de-sac obliteration and normal groups. No significant differences were observed in the rate of previous abdominal surgery (50.0% vs. 32.6%, P = 0.46), rate of POP - quantification system (POP-Q) ≥ 2 posterior prolapse (40.0% vs. 46.4%, P = 0.98), and effect of defecation symptoms on the prolapse quality of life (p-QOL) score (vaginal bulge emptying bowels: 2.5 vs. 3.5, P = 0.15; empty bowel feeling: 3 vs. 3, P = 0.72, constipation: 3.5 vs. 3, P = 0.58; straining to open bowels: 3.5 vs. 3, P = 0.82; empty bowels with fingers: 1 vs. 1, P = 0.55) between the cul-de-sac obliteration and normal groups. Multivariate analysis of risk factors for the cul-de-sac obliteration was performed for age, number of births, previous abdominal surgery, and presence of rectocele; however no significant risk factors were extracted. CONCLUSION: Predicting cul-de-sac obliteration preoperatively in patients undergoing POP surgery based on age, number of previous surgeries, previous abdominal surgeries, rectocele, and defecation symptoms is difficult.

Awareness of Infectious Disease Screening During Early Pregnancy and Knowledge About its Vertical Transmission in Japan: A Report from the Pregnant Women Health Initiative.

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.

Role of cervical cancer screening during prenatal checkups for infectious diseases: A retrospective, descriptive study.

OBJECTIVE: This study was conducted to evaluate the status and role of cervical cytology affected by human papillomavirus infection and other infectious diseases screened during routine prenatal checkups. METHODS: We retrospectively examined medical records containing the screening results for infectious diseases and cervical cancer in women who delivered neonates in our hospital from 2014 to 2017. RESULTS: Among 3393 deliveries, 18.8% of women underwent a regular cervical cancer screening within 1 year of becoming pregnant, and 2641 women underwent a cervical cytology screening during this pregnancy. The cytological diagnostic results showed that 2562 women (97.0%) were negative for intraepithelial lesions or malignancy, whereas 79 (3.0%) had abnormal results. Of those with abnormal cytology results, 70 had abnormal cytology that was newly detected in this pregnancy, and 42 had grade ≥1 cervical intraepithelial neoplasia lesions. Spatulas were the most frequently used cytological sampling instruments, followed by cotton swabs. Cervical cytology revealed no major adverse reactions during these pregnancies. CONCLUSIONS: Our results confirm the importance of screening for infectious diseases during pregnancy. Only 20% of the women underwent a regular pre-pregnancy cervical cytology screening. Cervical cytology screening during pregnancy may currently be playing a crucial role in preventing cervical cancer in Japan.

Bulky peritoneal carcinosarcoma with tiny high-grade serous carcinoma of the fallopian tube: a case report.

Peritoneal carcinosarcoma is a highly aggressive and uncommon neoplasm that has carcinomatous and sarcomatous components; the malignancy rarely localizes to the omentum. We report a case of a bulky peritoneal carcinosarcoma with tiny high-grade serous carcinoma of the fallopian tube. A 60-year-old female with a huge pelvic mass (12 cm in diameter) underwent a total abdominal hysterectomy, bilateral salpingo-oophorectomy, and omentectomy for tumor debulking. Pathological findings showed minimally invasive high-grade serous carcinoma of the left fallopian tube and carcinosarcoma of the omentum. Similar p53 diffuse immunostaining in the omental carcinosarcoma and the tubal carcinoma provides evidence for a clonal relationship between the two neoplasias. This case suggests a small serous carcinoma, originating in the tubal mucosa, subsequently became implanted in the omentum and grew preferentially, converting to a carcinosarcoma at a remote site.

Fetus-in-fetu: parasite or neoplasm? A study of two cases.

INTRODUCTION: Fetus-in-fetu is a rare congenital fetiform mass whose etiology is still controversial. We report two cases of fetus-in-fetu. CASE 1: A fetal retroperitoneal cystic tumor including two masses was detected by ultrasonography at 26 gestational weeks. The masses showed distinctive structures resembling a vertebral axis and were prenatally diagnosed as fetus-in-fetu. A resected specimen revealed two fetiform masses. CASE 2: An intracranial tumor with hydrocephalus was detected by ultrasonography at 19 gestational weeks. The pregnancy was terminated, and a postmortem examination revealed six fetiform masses with immature teratoma. DISCUSSION: The tumors may possibly consist of parasitic monozygotic diamniotic twins or highly differentiated teratomas.

Origin and mechanisms of formation of fetus-in-fetu: two cases with genotype and methylation analyses.

Fetus-in-fetu (FIF) is a condition in which a host infant has a fetus-like mass(es) within its body. We describe here results of molecular genetic analysis in two cases of FIF. In FIF-1, a male host had two retroperitoneal fetiform masses each with a vertebral column, and in FIF-2, a fetiform mass with vertebral column was present in the cranial cavity of a male host. Genotyping of each case using microsatellite markers showed that the host infant and its fetus(es) inherited one copy each of parental alleles and shared identical genotypes. These findings were confirmed by single nucleotide polymorphism (SNP) analysis using Affymetrix GeneChip Human Mapping 50K Array, and supported a monozygotic twin theory of FIF. Analysis of the methylation status was done in both cases at the differentially methylated region (DMR) within the human IGF2-H19 locus after bisulfite treatment, methylation-specific PCR, and cloning of PCR products. Normally, only the paternal allele is methylated and the maternal allele unmethylated in DMR. However, in FIF-1, 7 (46.7%) of 15 clones from a fetiform mass and 6 (66.7%) of 9 clones from the other mass showed an unmethylated paternal allele, while the methylation status of a host infant and its fetiform mass in FIF-2 was the same in all clones examined with normal patterns. These data suggest that in FIF-1, two isolated blastocysts originated from one zygote, one of the two was implanted into (or included by) the other blastocyst during the process of methylation, and such abnormal implantation may have occurred in FIF-2 after the establishment of methylation. This is the first case of FIF showing different methylation patterns between a host infant and fetiform mass.

Pregnancy outcome of fetuses with trisomy 18 identified by prenatal sonography and chromosomal analysis in a perinatal center.

To investigate the pregnancy outcome of fetuses affected with trisomy 18, we analyzed 63 cases diagnosed at our hospital from January 1993 to December 2004. Twenty-nine were males and 34 were females. Fifty-eight were prenatally diagnosed, and in 16 (27.6%) of them intrauterine fetal death (IUFD) occurred between 28 weeks and 41 weeks gestation (34.6 +/- 3.9 weeks, Mean +/- SD). Ten (17.2%) fetuses died during labor and their age ranged from 30 weeks to 40 weeks of gestation. The total number of cases ending in fetal demise was 26 (44.8%) and the mean gestational age at the time of fetal demise was 35.0 +/- 3.6 weeks (Mean +/- SD). All liveborn infants (n = 36) were born after 31 weeks gestation. In our study the preterm birth ratio for trisomy 18 is 34.8%, which is much higher than the ratio for the general population. Females are more likely than males to be long-term survivors. These data are helpful in the counseling of parents faced with the difficult decision of whether or not to continue a pregnancy with a fetus affected with trisomy 18.
