Risk factors for future osteoporosis in perimenopausal Japanese women.

OBJECTIVE: The aims of this study were to investigate trends in bone mineral density (BMD) loss and related factors in early postmenopausal women in Japan, identify risk factors for future osteoporosis, and predict osteoporosis before it occurs. METHODS: The study population consisted of women who were 50 to 54 years old at the time of the survey in 2002 or 2006. The study included a questionnaire and physical measurement findings (BMD, height, body weight [WT], body mass index [BMI], and handgrip strength). One hundred sixty-seven women continued to participate in the study and had BMD measurements at the 9- or 10-year follow-up of the Japanese Population-based Osteoporosis study. Statistical analyses were performed using Pearson correlation to examine each factor of physical measurement and BMD for lumbar spine (LS) and femoral neck (FN). The receiver operating characteristic curve of this data was also predictive of osteoporosis in 2011 for 2002 data; BMD at the age of 50 to 54 years was then used to predict the likelihood of being diagnosed with osteoporosis 9 and 10 years later. RESULTS: At the baseline in 2002 and 2006, WT, BMI, height, and handgrip strength were positively correlated with BMD. The optimal cutoff values for BMD in 2006 to predict osteoporosis in 2016 were LS less than 0.834 g/cm 2 and FN less than 0.702 g/cm 2 . These data were also predictive of osteoporosis in 2011 for 2002 data; applying this to the 2002 data, LS/FN had a sensitivity of 92%/100%, a specificity of 87%/81%, a positive predictive value of 55%/48%, and a negative predictive value of 98%/100%. The larger WT and BMI also resulted in a greater decrease in BMD of FN after 9 or 10 years. CONCLUSIONS: We have identified a cutoff value for BMD to predict future osteoporosis in menopausal women and found a negative correlation between WT and BMI in menopausal women and changes in BMD of the FN over the next 10 years.

Comparison of Surgical Results and Postoperative Recurrence Rates by Laparoscopic Sacrocolpopexy with Other Surgical Procedures for Managing Pelvic Organ Prolapse.

OBJECTIVES: Pelvic organ prolapse (POP) is relatively high for a gynecologic disease. Laparoscopic sacrocolpopexy (LSC) is currently the main surgical option for managing POP. The priority of the surgical treatment is preventing recurrence after the surgery. We presented the surgical outcome and recurrence rate of LSC and compared the data of LSC with that of other surgical procedures for managing POP to examine the effectiveness of LSC over other them. MATERIALS AND METHODS: We compared the results of 138 cases of LSC with other conventional procedures, namely 30 cases of total vaginal hysterectomy (TVH) combined with colporrhaphy anterior and posterior, 66 cases of the Manchester operation, and 68 cases of colpocleisis. We compared the age, body mass index, operative time, blood loss volume, postoperative hospital stay duration, rate of complications, recurrence rate, reoperation rate, and the cumulative recurrence rate after 10 years. RESULTS: The complication rate of LSC, TVH, the Manchester operation, and colpocleisis was 2.2%, 3.3%, 3.0%, and 4.4%; the recurrence rate 2.8%, 3.5%, 4.5%, and 8.7%; and the cumulative recurrence rate after 10 years 3.7%, 4.6%, 8.8%, and 18.2%. There was no significant difference between LSC and the other three groups. CONCLUSION: LSC seems to be an effective surgical option that requires a higher skill level than other surgical methods and has a longer operative time, lesser operative invasion, and a lower long-term recurrence rate. We will actively recommend LSC to those when appropriate.

Frequent PIK3CA mutations in eutopic endometrium of patients with ovarian clear cell carcinoma.

Recent studies have reported cancer-associated mutations in normal endometrium. Mutations in eutopic endometrium may lead to endometriosis and endometriosis-associated ovarian cancer. We investigated PIK3CA mutations (PIK3CAm) for three hotspots (E542K, E545K, H1047R) in eutopic endometrium in patients with ovarian cancer and endometriosis from formalin-fixed paraffin-embedded specimens by laser-capture microdissection and droplet digital PCR. The presence of PIK3CAm in eutopic endometrial glands with mutant allele frequency ≥ 15% were as follows: ovarian clear cell carcinoma (OCCC) with PIK3CAm in tumors, 20/300 hotspots in 11/14 cases; OCCC without PIK3CAm, 42/78 hotspots in 11/12 cases; high-grade serous ovarian carcinoma, 8/45 hotspots in 3/5 cases; and endometriotic cysts, 5/63 hotspots in 5/6 cases. These rates were more frequent than in noncancer nonendometriosis controls (7/309 hotspots in 5/17 cases). In OCCC without PIK3CAm, 7/12 (58%) cases showed multiple hotspot mutations in the same eutopic endometrial glands. In 3/54 (5.6%) cases, PIK3CAm was found in eutopic endometrial stroma. Multisampling of the OCCC tumors with PIK3CAm showed intratumor heterogeneity in three of eight cases. In two cases, PIK3CAm was detected in the stromal component of the tumor. Homogenous PIK3CAm in the epithelial component of the tumor matched the mutation in eutopic endometrial glands in only one case. Eutopic endometrial glands in ovarian cancer and endometriosis show high frequency of PIK3CAm that is not consistent with tumors, and multiple hotspot mutations are often found in the same glands. While the mutations identified in eutopic endometrium may not be driver mutations in the patient's cancer, these are still driver mutations but this specific clone has not undergone the requisite steps for the development of cancer.

Measures for Safe Laparoscopic Sacrocolpopexy: Preoperative Contrast-Enhanced Computed Tomography and Perioperative Ultrasonography.

Laparoscopic sacrocolpopexy is one of the most difficult laparoscopic surgical techniques. In this study, we report on our efforts to safely perform this procedure, which consists of suturing a piece of mesh onto the anterior longitudinal ligament using a nonabsorbent suture during mesh fixation onto the prepromontorium layer, which can lead to massive bleeding if a mistake is made, by performing preoperative and intraoperative image evaluation. Preoperative contrast-enhanced computed tomography was performed. Images in DICOM format were acquired, and three-dimensional vessel reconstruction was performed. After performing a peritoneal incision in the presacral area, ultrasonography was performed using a probe inserted through a 12-mm trocar into the abdominal cavity to re-confirm the absence of vessels near the planned suturing area. After ultrasonography, an Ethibond® suture was inserted through the anterior longitudinal ligament. In our hospital, 126 patients underwent the procedure, and none had a serious hemorrhage or required blood transfusion, indicating the safety of this modified procedure without separation of a wide presacral area. We believe that these techniques can be performed safely with minimal incision. However, we did not examine the efficacy of these techniques in this paper. Further studies are needed to determine whether this approach is suitable.

Research Article Quality of life after laparoscopic hysterectomy versus abdominal hysterectomy.

BACKGROUND: Laparoscopic surgery has been described as a minimally invasive surgery. The purpose of this study is to clarify its minimal invasive features using a patient questionnaire on the postoperative quality of life (QOL) over various time periods following either laparoscopic hysterectomy (LH) or abdominal hysterectomy (AH) and to compare the results. METHODS: This study enrolled 28 patients who underwent total hysterectomy for uterine fibroids in 2012 (14 AH cases and 24 LH cases) were enrolled in this study. The 36-Item Short Form Survey (SF-36) questionnaire was completed on postsurgical day 3; weeks 1, 2, and 4; and month 6. The results were compared between the two groups. RESULTS: Patients who underwent LH scored significantly higher on physical functioning on postoperative day 3 and week 2; physical role and bodily pain on day 3 and week 1; general health on postoperative day 3, weeks 1, 2, and 4, and month 6; social functioning on day 3; and emotional role on day 3 and week 1. No significant differences were found between vitality and mental health at any time point or in the categories above at any other time point. CONCLUSIONS: Postoperative QOL in LH cases was improved on day 3 and week 1; however, no significant differences between the LH and AH groups were found in most categories at week 4 and month 6. LH leads to superior short-term QOL early in the postoperative period relative to AH.

A case report of bladder and intestinal endometriosis, and the relationship between sex hormone receptor expression and PIK3CA mutation analysis.

BACKGROUND: Extragonadal endometriosis is a rare condition, and its disease manifestation and long-term prognosis have not been elucidated. We report an extragonadal endometriosis case controlled by drug therapy for 14 years with analysis of the sex hormone receptor expression and PIK3CA mutation. CASE PRESENTATION: The patient was diagnosed with bladder endometriosis at age of 30 years, and underwent bilateral nephrostomy and GnRHa therapy with add-back therapy. The patient was switched to dienogest therapy at age 35 and had hematuria and bloody stools at age 38. PET-CT revealed a 6-cm mass in the bladder with fluorodeoxyglucose accumulation and the diagnosis of endometriosis in the bladder, sigmoid colon, and cecum was confirmed after the biopsy result. The lesion's tubular structures were positive for the estrogen receptor, but only 30% positive for the progesterone receptor, and the H1047R mutation in PIK3CA was found in tubular structures of the bladder lesion. GnRHa therapy caused the tumors to shrink. CONCLUSION: Decreased progesterone receptor expression and oncogenic mutations may influence the course of less common and rare site endometriosis. Rare site endometriosis often requires long-term hormone therapy, and management should be tailored to the patient's life stage, keeping in mind complications, such as decreased bone density.

Reproductive Outcome of Infertile Patients with Fibroids Based on the Patient and Fibroid Characteristics; Optimal and Personalized Management.

AIMS: To analyze the detailed clinical course of infertile patients with uterine fibroids and to identify optimal and personalized treatment based on the patient or fibroid characteristics. METHODS: Retrospective analysis of a case series was performed on 176 infertile patients with fibroids. The patients were classified into different groups according to different treatments (conservative infertility treatment, myomectomy and non-myomectomy surgery). Patient or fibroid characteristics for different groups were analyzed for a possible correlation with the reproductive outcome. RESULTS: The cumulative pregnancy rates by conservative treatment plateaued in 1 year. Myomectomy improved the reproductive outcome in patients who did not conceive with conservative infertility treatments. The most important determinant of the reproductive outcome in patients by conservative treatment prior to surgery was a past patient history of pregnancy. The most important determinant of the reproductive outcome after myomectomy was patient age. CONCLUSION: Myomectomy should be considered when infertile patients with fibroids do not conceive within 1 year of conservative infertility treatments. The most important determinant of reproductive outcome after myomectomy is patient age. Therefore, for patients younger than 40, the treatment schedule should be carefully considered so that the patients can sufficiently benefit from myomectomy and assisted reproductive technology.
