Examination of fetal well-being evaluation metrics for fetal growth restriction as seen from Japan Obstetric Compensation Cause Analysis Report data.

Advances in perinatal care have improved the prognoses of both mothers and neonates; however, cerebral palsy continues to occur. In this study, we examined methods for the intragestational evaluation of the health of infants who later developed cerebral palsy. A retrospective review was conducted on light-for-dates cases among the 2113 cause analysis reports issued by the Japan Obstetric Compensation System between January 2009 and September 2018. In our examination, we determined that non-stress tests and ultrasonic Doppler tests were used to evaluate fetal well-being. Moreover, we observed cases in which additional testing was not performed even when fetal growth restriction (FGR) was identified. Appropriate management of FGR may help reduce the incidence of cerebral palsy.

Does local infiltration anesthesia on laparoscopic surgical wounds reduce postoperative pain? Randomized control study.

PURPOSE: Recently, endoscopic surgeries are widely performed in the gynecological field. Several studies on the use of local anesthesia for pain control after laparoscopic surgery have been conducted; however, its effects remain controversial. Herein, a randomized control study on gynecological laparoscopic surgeries was conducted to analyze the effectiveness of local anesthesia on postoperative pain. METHODS: Patients who underwent laparoscopic surgeries due to gynecologic benign diseases or endometrial cancer in the early stage were enrolled, and randomly divided into intervention (injected with levobupivacaine), and control (injected with saline) groups. The primary outcome was the dosage of analgesic consumption within 12 hours postoperatively. RESULTS: A total of 147 patients were enrolled in the intervention group and 147 in the control group. The outcome of local anesthesia was not significantly different between the two groups during the whole analysis. We analyzed the effects of local anesthesia in the laparoscopic surgery subgroup. The dosage of analgesic consumption within 12 h after a laparoscopic hysterectomy (TLH) or TLH with pelvic lymph node dissection (TLH+PLD) in the intervention group was significantly smaller than that in the control group. CONCLUSION: Local infiltration anesthesia can effectively reduce postoperative pain in patients who underwent TLH or TLH +PLD.

[A Case Report of Surgery and Chemotherapy for a Patient with Rapidly Progressing Breast Cancer during Pregnancy].

A 33-year-old woman became aware of a right breast mass at her 28th week of pregnancy. From the biopsy results, we diagnosed her with right breast cancer. At her 33rd week of pregnancy, she underwent modified radical mastectomy (pT2N3aM0, Stage III C, ER-negative, PR-negative, HER2-positive), and she elected to receive adjuvant therapy after the surgery during her pregnancy. She received the first course of EC (epirubicin plus cyclophosphamide) therapy on the 13th postoperative day (35 weeks of gestation) and gave a natural, vaginal delivery at 36 weeks and 5 days of gestation. On the 4th day after birth, the patient noticed a contralateral left breast mass and was diagnosed with left breast cancer, after core needle biopsy. She received 4 courses of EC therapy and is currently undergoing PTX plus HER (paclitaxel plus trastuzumab) therapy. Regarding chemotherapy during pregnancy, we recommend that there is no need to perform artificial preterm birth, because chemotherapy has little influence on children after their second-trimester. After the second-trimester, chemotherapy can be safely performed.

The Analysis of Cell Cycle-related Proteins in Ovarian Clear Cell Carcinoma Versus High-grade Serous Carcinoma.

In Japan, the frequency of ovarian clear cell carcinoma (CCC) is twice as high as that in the United States and Europe. Often, patient prognosis with CCC is poor because of chemoresistance. Here, we focus on the cell cycle, which is one of the mechanisms of chemoresistance. To detect the informative markers and improve the strategy of chemotherapy for CCC, we performed immunohistochemical staining of cell cycle-related proteins in ovarian malignant tumors. We detected that each of the 29 samples of CCC and high-grade serous carcinoma (HGSC) were necessary to reveal the significant differences in immunostaining and prognosis. We performed the immunostaining analysis using the antibodies of cell cycle-related proteins such as Ki-67, Cdt1, MCM7, and geminin. The positive rate of Cdt1 in the CCC group was significantly higher than that in the HGSC group (P<0.0001). However, the positive rate of geminin in the HGSC group was significantly higher than that in the CCC group (P<0.0001). The overall survival of CCC patients with high labeling index of Cdt1 was significantly worse than that of CCC patients with low labeling index of Cdt1 (P=0.004). The study results suggested that the cancer cells of CCC and HGSC exist in the G1 phase and S, G2, and M phases, respectively. The differences in cell cycle of CCC might be one of the reasons for chemotherapy resistance. Further investigations are necessary to reveal the usefulness of Cdt1 as a biomarker in CCC.

Massive cystic degeneration of a uterine leiomyoma in a patient with autosomal dominant polycystic kidney disease.

BACKGROUND: A uterine cyst occurring as an extrarenal manifestation of autosomal dominant polycystic kidney disease (ADPKD) is extremely rare. CASE: A 46-year-old Japanese woman was referred with a large abdominal mass causing severe abdominal distension. A large uterine cyst as an extrarenal manifestation of ADPKD was strongly suspected. First, we managed this patient by aspirating the cyst fluid through a small laparotomy. A year later, the cyst recurred and the patient underwent hysterectomy. Massive cystic degeneration of a uterine leiomyoma was diagnosed histologically. CONCLUSION: We described the rare case of massive cystic degeneration of a uterine leiomyoma in a patient with ADPKD, in which a causal relationship was suspected.
