Not taking sick leave for gynecologic cancer treatment is negatively associated with returning to the same workplace.

BACKGROUND: Gynecologic cancers are one of the most common types of malignancies in working-age women. We aimed to determine the factors that impede women from returning to the same workplace after treatment for such cancers. METHODS: A questionnaire-based survey was conducted on 194 women who underwent treatment for gynecologic cancer at the Okayama University (≥1 year after cancer treatment and <65 years of age). We performed a logistic regression analysis to determine the relationship between returning to the same workplace and not taking sick leave. RESULTS: The median age at diagnosis was 49.0 years, and the median time from cancer treatment to questionnaire completion was 3.8 years. Not returning to the same workplace was positively associated with not being regularly employed (P = 0.018), short work time per day (P = 0.023), low personal income (P = 0.004), not taking sick leave (P < 0.001), advanced cancer stage (P = 0.018) and long treatment time (P = 0.032). Interestingly, not taking sick leave was strongly associated with not returning to the same workplace in the multivariable analysis (P < 0.001). CONCLUSIONS: Not taking sick leave likely was negatively associated with returning to the same workplace after the treatment for gynecologic cancer. Therefore, we suggest that steps be taken to formally introduce a sick leave system over and above the paid leave system in Japan.

The Combination of D-dimer and Glasgow Prognostic Score Can Be Useful in Predicting VTE in Patients with Stage IIIC and IVA Ovarian Cancer.

Cancer patients have increased risk of venous thromboembolism (VTE) that must be assessed before treatment. This study aimed to determine effective VTE biomarkers in gynecologic cancer (GC). We investigated the correlation between D-dimer levels, Khorana risk score (KRS), Glasgow prognostic score (GPS), and VTE in 1499 GC patients (583 cervical cancer (CC), 621 endometrial cancer (EC), and 295 ovarian cancer (OC) patients) treated at our institution between January 2008 and December 2019. χ2 and Mann-Whitney U-tests were used to determine statistical significance. We used receiver operating characteristic-curve analysis to evaluate the discriminatory ability of each parameter. D-dimer levels were significantly correlated with KRS and GPS in patients with GC. VTE was diagnosed in 11 CC (1.9%), 27 EC (4.3%), and 39 OC patients (13.2%). Optimal D-dimer cut-off values for VTE were 3.1, 3.2, and 3.9 µg/ml in CC, EC and OC patients, respectively. D-dimer could significantly predict VTE in all GC patients. Furthermore, D-dimer combined with GPS was more accurate in predicting VTE than other VTE biomarkers in stage IIIC and IVA OC (AUC: 0.846; p<0.001). This study demonstrates that combined D-dimer and GPS are useful in predicting VTE in patients with OC.

Surgically treated genital chronic graft-versus-host disease in women: A report of three cases.

Hematopoietic stem cell transplantation (HSCT) is a crucial treatment for hematological malignancy. Gonadal dysfunction occurs at an early stage after this treatment, and such patients may require hormone replacement therapy. Genital chronic graft-versus-host disease is a lesser-known complication of HSCT that begins with vulvar discomfort and dysuria and progresses to sexual dysfunction and retention of menstrual blood due to vaginal stenosis and obstruction; thus, significantly impairing the patient's quality of life. We describe three women who underwent vaginal reconstruction because of genital chronic graft-versus-host disease. We discuss the surgical techniques, including double cross plasty that were performed in each case. Surgical interventions enabled the continuation of HRT and facilitated sexual intercourse. In conclusion, gynecologists should be aware that genital chronic graft-versus-host disease can occur after HSCT, and that surgical treatment options are available to improve patients' symptoms and quality of life.

Inflammation of the adipose tissue in the retroperitoneal cavity adjacent to pelvic endometriosis.

AIM: Peritoneal endometriosis is a chronic inflammatory disease particularly associated with macrophages. Of note, adipose tissues with fibrotic changes in the context of peritoneal endometriotic lesions are often observed during surgery. However, the characteristics of fibrotic adipose tissues in endometriosis are still unknown. In this study, we investigated the inflammatory status of retroperitoneal adipose tissues adjacent to pelvic endometriotic lesions. METHODS: Thirty-two patients who underwent surgical treatment were assigned to either the endometriosis (n = 16) or the control (n = 16) groups. Retroperitoneal adipose tissues around the uterus were collected from patients in both groups. Fibrosis was evaluated via Masson's trichrome staining. Macrophage infiltration, the expression of fatty acid-binding protein 4 (FABP4), and angiogenesis in the retroperitoneal adipose tissues were evaluated via immunohistochemistry. The mRNA expression levels of cytokines was also evaluated in the adipose tissues using real-time PCR. RESULTS: There was more fibrosis and angiogenesis in the adipose tissues adjacent to the endometriotic lesions with a significantly higher level of infiltration of macrophages and a predominance of the M1 type in the endometriosis group compared to the control group. In addition, FABP4 positivity in the adipose tissues of the peritoneum was significantly higher in the endometriosis group versus the control group. Moreover, the mRNA expression levels of FABP4, VEGF, and proinflammatory cytokines were also significantly higher in the endometriosis group. CONCLUSION: Altogether, our results showed that the adipose tissue adjacent to endometriotic lesions are inflamed with fibrosis and angiogenesis.

Slow Fetal Heart Rate before Miscarriage in the Early First Trimester Predicts Fetal Aneuploidy in Women with Recurrent Pregnancy Loss.

Establishing whether miscarriages result from fetal aneuploidy or other factors is important for treating recurrent pregnancy loss. We examined the relationship between fetal heart rate (FHR) before miscarriage in the early first trimester and fetal karyotype, analyzing 223 pregnant women with recurrent pregnancy loss. Among the pregnancies, 110 resulted in live births regarded as normal karyotype (the Norm-group). The other 113 pregnancies ended in miscarriage, and we categorized them into groups based on fetal karyotype, determined by chorionic villus sampling: the Misc-NK (normal karyotype) group, n=35 euploid cases; the Misc-CA1 (chromosomal abnormality) group, n=18 cases of aneuploidy with trisomies 13/18/21, Turner's syndrome, or Klinefelter's syndrome; and the Misc-CA2 subgroup, n=60 cases of other aneuploidies excluding those in the Misc-CA1 group. We compared the groups' regression line slopes and intercepts for FHR by an analysis of covariance. The FHRs of the Norm, Misc-NK and Misc-CA1 groups increased from 36 to 49 days after fertilization, but did not significantly differ across these groups. The Misc-CA2 group's FHR did not increase and significantly differed from the other three groups (p<0.01). These results suggest that the absence of an increase in FHR in early pregnancy may indicate the presence of chromosomal abnormalities causing miscarriage.

Trapezial Design Technique for Autogenous Bone Graft in Esthetic Zone Implant Treatment.

We report bone augmentation for alveolar bone loss at the bottom of the nasal cavity in conjunction with simultaneous implant placement in the same operative field in the esthetic zone. The patient was a 33-year-old man who was referred to us requesting implant treatment after undergoing tooth extraction (#12) due to root fracture. An examination was performed using cone beam computed tomography (CT) and simulation software. The results indicated insufficient volume of labial bone for the requested procedure, especially at the planned site of the implant neck. Therefore, bone augmentation was performed at the apical site of the implant socket (alveolar bone at the bottom of the nasal cavity). Because the surgical line of the harvest site formed a trapezoidal shape, the procedure was named the "Trapezial Design Technique". Assessment of complications (Barone & Covane classification), success (Albrektsson classification), and observation of labial bone using cone beam CT were performed postoperatively. No com-plications were observed at 27 months after prosthetic treatment. The implant and the tissue surrounding it were in a stable condition. This indicates that this procedure is effective in placing an implant with simultaneous bone augmentation in the esthetic zone.

Adenosine Deaminase Family Acting on RNA 1 (ADAR1) May Be a De Novo Target for Endometriosis Treatment.

BACKGROUND/AIM: Adenosine deaminase family acting on RNA 1 (ADAR1) expression was examined to determine its correlation with endometriosis. The biological functions and inhibitory effects of ADAR1 knockdown were investigated in a human endometriotic cell line. MATERIALS AND METHODS: ADAR1 was examined in patients with and without endometriosis using reverse transcription polymerase chain reaction (RT-PCR), and the apoptotic expression of ADAR1 small interfering RNA (siRNA) was confirmed using flow cytometry. The biological functions and inhibitory effects of ADAR1 knockdown were investigated using RT-PCR in a 12Z immortalized human endometriotic cell line. RESULTS: ADAR1 expression was significantly higher in patients with endometriosis than in those without (p<0.001). ADAR1 siRNA increased early and late apoptosis, compared to the mock (24.83%) and control (19.96%) cells. ADAR1 knockdown led to apoptosis through MDA5, RIG-I, IRF3, IRF7, caspase 3, caspase 7, and caspase 8 expression in the cell lines. CONCLUSION: ADAR1 is a potential novel therapeutic target in endometriosis.

Total laparoscopic wedge resection for an intramural ectopic pregnancy using an intraoperative ultrasound system: A case report.

Intramural pregnancy is a rare form of ectopic pregnancy, and the optimal treatment remains uncertain. We describe a 33-year-old woman (gravida 2, para 0) who visited our hospital with suspected ectopic pregnancy. The patient was asymptomatic and hemodynamically stable. Transvaginal ultrasonography revealed pregnancy at 6 weeks of gestation and a gestational sac and fetal heartbeat in the anterior muscular layer of the uterus, away from the endometrium. The fetal sac measured 26 mm. The serum human chorionic gonadotropin (hCG) level had increased to 27 655 mIU/mL. Accordingly, the patient was diagnosed with an intramural ectopic pregnancy and underwent total laparoscopic wedge resection using intraoperative ultrasonography. The postoperative course was uneventful, and she was discharged after 4 days. Her serum hCG level normalized at 26 days postoperatively. This case indicates that intraoperative laparoscopic ultrasonography seems viable for treating intramural pregnancies.

Surgical training in extraperitoneal laparoscopic para­aortic lymphadenectomy for the treatment of gynecological cancer using a Thiel­embalmed cadaver.

The extraperitoneal laparoscopic approach (ELPAN) for para-aortic lymphadenectomy provides excellent visibility of the left side of the aorta, thus facilitating surgery in the retroperitoneal space. This technique is highly complex compared with the transperitoneal approach. In particular, advanced techniques are required to develop an appropriate surgical field in the narrow retroperitoneal space; therefore, surgeons need to undergo a significant amount of training to become competent. A variety of tools are available for surgical training but are limited by their ability to reproduce complex anatomy. Thus, cadavers may represent the most suitable tool for learning this unique technique. The present study describes a surgical training protocol for the ELPAN technique using a Thiel-embalmed human cadaver and provides a step-by-step description of the ELPAN technique performed at Okayama University (Okayama, Japan). A 72-year-old Thiel-embalmed female cadaver was used to develop a protocol for surgical training in the ELPAN technique that effectively reproduced the methodology required in clinical practice. A training method for ELPAN surgery was developed and successfully completed using the Thiel-embalmed cadaver that secured the surgical field in the retroperitoneal space and permitted resection of the lymph nodes. The Thiel-embalmed cadaver tissue possessed excellent properties for surgical training, including color tone, flexibility, and the membrane structure of connective and fat tissues. In addition, this method of fixation preserved stiffness and elasticity of the peritoneum, although large vessels were slightly fragile and poorly extensible. Surgical training using a Thiel-embalmed human cadaver represents a valuable option for learning the ELPAN surgical technique. However, this technique may be unsuitable for training in perivenous manipulation. To the best of our knowledge, this is the first report to describe the use of Thiel-embalmed cadavers as a tool for surgeons to undergo training in the ELPAN technique.

Evidence-based assessment: evaluation of the formocresol versus ferric sulfate primary molar pulpotomy.

PURPOSE: Formocresol and ferric sulfate were evaluated as pulpotomy medicaments using evidence-based dentistry principles. Formocresol has been challenged as a potential carcinogen and mutagen, leading to consideration of ferric sulfate. METHODS: The PICOT statement was: (P) In human carious primary molars with reversible coronal pulpitis, (I) does a pulpotomy performed with ferric sulfate, (C) compared with formocresol, (O) result in dinical/radiographic success, (T) in time periods up to exfoliation? Relevant papers (N=894) were identified from databases and inclusion criteria were applied; 94 papers remained (randomized clinical trials [RCTs]=7; clinical trials [CTs]=28; case-control studies=14; opinions, cohort, and cross-sectional studies=4; reviews=22; irretrievable papers=19). Three RCTs and 10 CTs (total teeth: formocresol=753; ferric sulfate=90) were meta-analyzed; 1 RCT and 1 CT were tested for homogeneity (odds ratios; 95% confidence intervals); 3 RCTs and 10 CTs were examined by student's t test. RESULTS: Clinical data indicated ferric sulfate was significantly more successful than formocresol (OR=1.95; CI=1.01-3.80). Radiographic data indicated no difference between medicaments (OR=0.90; CI=0.58-1.39). Medicaments did not differ with t-tests of clinical (P>.10) and radiographic (P>.50) data. CONCLUSIONS: This evidence-based assessment concluded that, in human carious primary molars with reversible coronal pulpitis, pulpotomies performed with either formocresol or ferric sulfate are likely to have similar clinical/radiographic success.
