Weight reduction using a formula diet recovers menstruation in obese patients with an ovulatory disorder.

Aim: To determine the effectiveness of a formula diet in weight reduction and the recovery of menstruation in obese patients with ovulatory disorders. Methods: After the enrollment of 39 obese women with ovulatory disorders, they replaced one or two of their three normal meals with a microdiet (MD) (240 kcal/meal) for 24 weeks. Physical, endocrinological, and biochemical tests were conducted before and at 12 and 24 weeks of the study. Of the 39 women enrolled, 26 were not taking clomiphene. They were divided into three groups according to their body weight outcomes and then analyzed for menstruation recovery. Results: A weight reduction of ≥5% was observed in 31 (81.5%) of the 39 women. There were significant decreases in the body weight and Body Mass Index during the study. Menstruation returned in 18 (69%) of the 26 patients without clomiphene treatment, with the recovery being significantly more prevalent in the groups (totally 81.0%) that exhibited a 5%-10% weight reduction and ≥10% weight reduction, compared to the group with a <5% weight reduction. Conclusion: The use of a formula diet effectively reduced the patients' body weight and led to the recovery of menstruation in these obese patients with ovulatory disorders.

Is It Possible to Perform Less Radical Surgery for Invasive Uterine Cervical Cancer?

BACKGROUND/AIMS: A retrospective analysis was performed to evaluate the possibility of less radical surgery for early-stage invasive uterine cervical cancer without compromising the oncological outcome. METHODS: The analysis was performed on 175 patients with invasive uterine cervical cancer in FIGO stage IA2-IIB, all of whom underwent primary radical hysterectomy. Relationship of tumor size with the incidence of pathologic parametrial involvement and the pelvic lymph node metastasis were investigated. RESULTS: Fifty-one patients had tumor size ≤2 cm and 124 had tumor size >2 cm. Patients with tumor size ≤2 cm had a significantly lower incidence of parametrial invasion (p < 0.0001), lymph node metastasis (p < 0.0001), lymph vascular space involvement (p < 0.0001) and recurrence (p = 0.0002) than patients with tumor size >2 cm. Five-year relapse-free survival rate was 98 and 73%, respectively (p = 0.0004). CONCLUSION: It is suggested that less radical surgery may be appropriate for some cases with tumor size <2 cm.

A very rare case of endometriosis presenting with massive hemoperitoneum.

Endometriosis is a cause of acute abdomen because of the leakage or rupture of endometriotic cyst and tubo-ovarian abscess. However, massive hemoperitoneum as a cause of acute abdomen with endometriosis is very rare. We herein present a case of a 48-year-old woman who was urgently referred to our clinic with colic, abdominal distension, and hypovolemic shock during menstruation. Ultrasonography revealed massive hemorrhagic ascites. Exploratory laparoscopy was urgently performed to achieve hemostasis. The volume of hemoperitoneum evacuated from the pelvis was 1,890 mL. Although the uterus and bilateral ovaries were normal, fresh bleeding was observed from endometriosis on the left cul-de-sac peritoneum, and hemostasis was successfully performed. The potential occurrence of hemorrhagic shock associated with endometriosis, depending on the implantation site, needs to be recognized.

Potential proton beam therapy for recurrent endometrial cancer in the vagina.

Proton beam radiotherapy mainly has been used in the gynecological field in patients with cervical cancer. The efficacy of proton beam therapy in patients with recurrent endometrial cancer has not yet been determined. A 77-year-old endometrial cancer patient presented with recurrence in the vagina without distant metastasis following hysterectomy. A hard mass measuring 6 cm originated from the apex of the vagina, surrounded the vaginal cavity, and infiltrated the proximal and distal vagina. The patient received proton beam radiotherapy using a less invasive particle treatment system while minimizing the dose to the surrounding normal tissues. The dose to the planning target volume was 74 Gy (relative biological effectiveness) with 37 fractions. The patient was treated with 150-210-MeV proton beams for 53 days. Proton beam therapy led to the disappearance of tumors without any complications except for grade 1 cystitis although evidence of further complications is not available past our 6-month follow-up period. Proton beam therapy may become a useful treatment modality for recurrent endometrial cancer as well as cervical uterine cancer.

Identification of new risk factors for wound separation in gynecologic malignancy surgery.

AIM: The purpose of this study was to compare prophylactic subcutaneous drainage plus subcuticular sutures versus staples for the risk of wound separation after skin closure following gynecologic malignancy surgery, and to investigate the risk factors of this procedure. MATERIAL AND METHODS: Patients were divided into two groups: 120 patients who were treated with subcutaneous drainage plus subcuticular sutures (Suture group) and 201 patients with staples plus subcutaneous sutures (Staples group). In the Suture group, subcuticular tissue was approximated with interrupted 4-0 polydioxanone sutures, and adhesive closure strips were used on the skin surface. A 3.3-mm closed drainage was implicated in subcutaneous tissue. In the Staples group, subcutaneous tissue was approximated with interrupted polyglactin (Vicryl, Ethicon) sutures. RESULTS: Baseline characteristics were not significantly different between the two groups. Mean operation times were compatible (201 vs 196 min, P = 0.16). The incidence of wound separation was less in the Suture group than in the Staples group (3/120 vs 17/201, P = 0.033). Multiple logistic regression analysis revealed that the Staples group was an independent risk factor for wound separation (odds ratio 7.34, 95% confidence interval: 1.59-33.91, P = 0.011), independent of obesity, International Federation of Gynecology and Obstetrics stages, and operation time. None of the 14 obese patients in the Suture group showed surgical wound separation. CONCLUSIONS: The combination of a prophylactic subcutaneous drain and subcuticular sutures reduced wound separation after skin closure following gynecologic malignancy surgery. With the information regarding risk factors established in this study, the above method provides the best results to minimize the risk, particularly in obese patients.

Menstrual restoration in severe panhypopituitarism many years after cranial irradiation for suprasellar germinoma.

Purpose: We report a very rare case showing menstrual restoration in severe pan-hypopituitarism many years after cranial irradiation for suprasellar germinoma. Case: A 30-year-old, almost primarily amenorrheic woman with severe panhypopituitarism presented with cyclic genital bleeding for the previous five months. She had menstruated once, when she was 13 years old. When she was 14 years old, she was diagnosed with a suprasellar germinoma measuring 10 mm in diameter, which led to diabetes insipidus. Cranial irradiation with a total dose of 24 Gy and chemotherapy resulted in complete tumor remission. She developed severe hypopituitarism [luteinizing hormone (LH) = 0.4 mIU/mL, follicle-stimulating hormone (FSH) = 1.7 mIU/mL, and serum estradiol (E2) level < 10 pg/mL]. She had received multiple hormone replacement therapies for many years. When she was 29 years old, she expressed a desire to become pregnant. Serum gonadotropin and E2 levels increased (LH = 5.8 mIU/mL, FSH = 5.9 mIU/mL, and E2 = 58 pg/mL). She conceived with clomiphene therapy, and then delivered a healthy baby. Eight months after parturition, her basal body temperature and serum progesterone levels indicated recovery of ovulatory cycles. Ten months after parturition, she also spontaneously conceived. Conclusion: Menstrual restoration is very rare in severe panhypopituitarism after cranial irradiation. A relatively low dose of irradiation and small tumor size may have contributed to the recovery of menstruation in our patient.

Cryotherapy for massive vulvar lymphatic leakage complicated with lymphangiomas following gynecological cancer treatment.

Vulvar lymphatic leakage is a severe complication associated with gynecological cancer treatments. However, standard treatment strategies have not yet been determined. We encountered a rare case of a 76-year-old multiparous woman suffering from massive lymphatic fluid leakage from the entire vulva, and papules developed and were identified as lymphangiomas. A large amount of straw-colored discharge continued from all vulvar papules, which extended over the mons pubis. Nine years ago, the patient had undergone a radical hysterectomy with concurrent chemoradiation for uterine cervical cancer treatment. Her serum albumin level was 1.9 mg/dl, which was attributed to the loss of a large amount of lymph fluid due to leakage from the vulva. Her quality of life gradually decreased because of general fatigue and the need for frequent diaper exchanges every 2 h. The patient received a less-invasive treatment with cryotherapy using liquid nitrogen. She also received a multimodality treatment consisting of the intravenous administration of albumin, massage of the lower limbs and intensive rehabilitation. Cryotherapy was administered once a week for 3 months. Her discharge almost stopped and vulvar lymphangiomas decreased without any major complications. To the best of our knowledge, this is the first case report of massive lymphatic leakage complicated with vulvar lymphangiomas. Additionally, this case may represent the first successful treatment of vulva lymph leakage by cryotherapy without recurrence. Cryotherapy may have the potential to improve the quality of life as a less-invasive treatment for gynecological cancer survivors without serious complications.

Can pelvic lymphadenectomy be omitted in stage IA2 to IIB uterine cervical cancer?

OBJECTIVES: The aims of this study were to predict pelvic lymph node metastasis in uterine cervical cancer before surgery and to evaluate the potential efficacy of omitting pelvic lymphadenectomy. MATERIALS AND METHODS: A total of 163 patients with invasive uterine cervical cancer in FIGO stage IA2 to IIB, all of whom underwent primary radical hysterectomy with pelvic lymphadenectomy, participated in this study. RESULTS: The incidences of pelvic lymph node metastasis in stage IA2, stage IB1, stage IB2, stage IIA, and stage IIB cervical cancer were 0% (0/12), 17% (13/76), 22% (6/27), 33% (8/24), and 63% (15/24), respectively. A significant difference was observed in overall survival with nodal metastasis status (P < 0.0001). Univariate analysis revealed that parametrial invasion (P < 0.0001), tumor markers (P = 0.0006), tumor size greater than 2 cm (P < 0.0001), tumor size less than 3 cm (P = 0.0009), and tumor size greater than 4 cm (P = 0.0024) were correlated with pelvic lymph node metastasis. However, multivariate analysis revealed that parametrial invasion (P = 0.01; odds ratio, 3.37; 95% confidence interval, 1.31-9.0) and tumor size greater than 2 cm (P = 0.005; odds ratio, 4.93; 95% confidence interval, 1.54-22.01) were independently associated with nodal metastasis. CONCLUSIONS: Pelvic lymphadenectomy may be avoided in patients with negative parametrial invasion and a tumor size less than 2 cm, thereby minimizing postoperative complications.

Current human T-cell lymphotropic virus type 1 mother-to-child transmission prevention status in Kagoshima.

The aim of this study was to assess the current human T-cell lymphotropic virus type 1 (HTLV-I) mother-to-child transmission (MTCT) prevention system in Kagoshima Prefecture. We investigated the rate of carrier pregnant women from obstetrics facilities in Kagoshima by mail in 2012 and compared our results with previous study results. We interviewed carrier pregnant women about their choices for infant nutrition, and we interviewed midwives about the follow-up system. In 2012, 8719 screening tests were performed, covering 58.1% of all pregnant women in Kagoshima; the rate of carrier pregnant women was 1.3%. Of 59 carriers, 39 chose short-term breast-feeding. The HTLV-I carrier rate among pregnant women in Kagoshima has declined. The current HTLV-I MTCT prevention system in Kagoshima is effective, but not sufficient. To bring the nutrition methods to completion, various types of support are needed. Further studies will elucidate many unsolved problems concerning MTCT.

Concentrated ascites re-infusion therapy for pseudo-Meigs' syndrome complicated by massive ascites in large pedunculated uterine leiomyoma.

Pseudo-Meigs' syndrome accompanied by massive ascites in uterine leiomyoma is rare. We encountered a rare case of a 37-year-old, nulliparous woman with a lower abdominal tumor and severe abdominal distention due to massive ascites. Serum cancer antigen 125 and vascular endothelial growth factor levels were elevated to 1007.9 U/mL and 103 pg/mL, respectively. She was tentatively diagnosed with ovarian cancer. Emergency concentrated ascites re-infusion therapy was performed to improve dyspnea, abdominal pain, and her preoperative respiratory condition. Concentrated ascites re-infusion therapy eliminated dyspnea and abdominal discomfort without decreasing serum albumin levels. The patient underwent laparotomy, which revealed a fist-sized pedunculated uterine leiomyoma arising from the right uterine fundus. Myomectomy was performed. Pseudo-Meigs' syndrome mimics advanced ovarian cancer due to massive ascites and markedly elevated serum cancer antigen 125 and vascular endothelial growth factor levels. Concentrated ascites re-infusion therapy was effective in improving the subjective symptoms of pseudo-Meigs' syndrome and the patient's preoperative condition.

Major causes of impractical brachytherapy in elderly patients with uterine cervical cancer.

AIM: Incomplete brachytherapy is a major risk factor for recurrence. However, high-dose-rate intracavitary brachytherapy has not been assessed adequately in elderly patients with invasive cervical cancer. The present study investigated the clinical importance of intracavitary brachytherapy and risk factors of incomplete intracavitary brachytherapy in elderly patients with cervical cancer. MATERIAL AND METHODS: Subjects were 76 patients aged 70-89 years old with invasive cervical cancer. All subjects were recruited between January 1997 and September 2010, and were planning to receive external beam radiation therapy followed by high-dose-rate intracavitary brachytherapy. Survival rates and the incidence of complications were compared between the 70s and 80s age groups. Risk factors for recurrence in elderly patients were evaluated using multivariate analysis, and risk factors for impractical intracavitary brachytherapy were also estimated. RESULTS: No significant differences were observed in 3-year progression-free survival rates or the incidence of complications in the two age groups. Cox multivariate analysis showed that histology (non-squamous cell carcinoma), incomplete intracavitary brachytherapy, and lymph node swelling were significant prognostic factors for recurrence. Impractical application was the major reason for incomplete treatment. Multiple logistic regression analysis revealed that a previous history without vaginal births (P = 0.016) was an independent risk factor for the impractical application, independent of tumor diameter ≥ 4 cm (P = 0.007). CONCLUSIONS: Incomplete intracavitary brachytherapy decreased the survival rates of elderly patients. Larger tumors and patients without a history of vaginal births were the two major causes of impractical intracavitary brachytherapy, which may be fatal, especially in elderly patients with bulky tumors.

Systemic thromboembolism after anti-cancer chemotherapy in a woman with ovarian germ cell tumor.

A high cure rate of ovarian germ cell tumors was achieved by establishment of a cisplatin-containing regimen. We encountered a rare case of a 33-year-old, nulligravida Japanese woman with systemic thromboembolism following anti-cancer chemotherapy with cisplatin, etoposide, and bleomycin in ovarian germ cell tumor. She suffered from brain infarction, multiple embolisms in the bilateral pulmonary artery and pelvic vein, and a broad range of deep vein thromboses in the right extremities vein. When thrombosis is detected during anti-cancer chemotherapy, we must investigate whether the presence of thrombosis is systemic or local.

Decreasing full-term neonatal birthweight over the past 2 decades in a single institute in Japan.

AIM: The aim of this study was to investigate whether full-term neonatal birthweight is decreasing or not. MATERIAL AND METHODS: Subjects were selected from the registration database of full-term singletons from a single local practitioner at two time-points, 1991 (n = 750) and 2011 (n = 442). Maternal age, parity, and smoking habits were recorded. Baseline characteristics included pre-pregnancy bodyweight (BW), body mass index (BMI), bodyweight before parturition, and weight gain during pregnancy. Neonatal birthweight and height were recorded. Variables correlated with neonatal size were investigated. RESULTS: Male birthweight decreased from 3248 ± 409 (n = 373) to 3149 ± 430 g (n = 230) (P < 0.001). Female birthweight also decreased from 3148 ± 378 (n = 377) to 3063 ± 343 g (n = 212) (P < 0.01). Gestational age was shorter (40.1 ± 1.1 to 39.6 ± 1.1 weeks, P < 0.001). Pre-pregnancy maternal BMI did not change (20.7 ± 2.6, n = 750 to 20.5 ± 2.7, n = 442). Weight gain during pregnancy decreased (11.3 ± 3.8 to 10.8 ± 3.4 kg, P < 0.05) and was positively correlated with birthweight (P < 0.001). On multiple regression analysis, time was inversely correlated with birthweight, while it was positively correlated with pre-pregnancy BMI, weight gain during pregnancy, and gestational age. CONCLUSIONS: In addition to maternal slenderness, increasing lower weight gain during pregnancy and medical intervention by physicians may in part contribute to the decrease in full-term birthweight over the past 2 decades.

Detection of Fusobacterium nucleatum in chorionic tissues of high-risk pregnant women.

AIM: This study was undertaken to investigate the existence of a periodontopathic bacterium, Fusobacterium nucleatum, in chorionic tissues of pregnant women, and the effects of F. nucleatum on human chorion-derived cells. MATERIALS AND METHODS: Oral and chorionic tissue samples were collected from 24 high-risk pregnant women and 15 normal pregnant women. The presence of F. nucleatum in the samples was detected using polymerase chain reaction. Chorion-derived cells and Toll-like receptor (TLR)-2 or TLR-4 gene-silenced chorion-derived cells were stimulated with F. nucleatum lipopolysaccharide (LPS). Interleukin (IL)-6 and corticotrophin-releasing hormone (CRH) levels in the culture supernatants were measured using ELISA. RESULTS: F. nucleatum was detected in all oral samples and seven chorionic tissues from the high-risk pregnant women, but was not detected in chorionic tissues from the normal pregnant women. F. nucleatum LPS significantly increased IL-6 and CRH secretion by chorion-derived cells. The F. nucleatum LPS-induced IL-6 and CRH levels were significantly reduced in TLR-2 or TLR-4 gene-silenced chorion-derived cells. CONCLUSIONS: We suggest that F. nucleatum is detected in chorionic tissues of high-risk pregnant women, but not in chorionic tissues of normal pregnant women, and that F. nucleatum induces IL-6 and CRH production via both TLR-2 and TLR-4 in chorion-derived cells.

Large parasitic myomas in abdominal subcutaneous adipose tissue along a previous myomectomy scar.

The incidence of iatrogenic parasitic uterine myomas associated with the use of a laparoscopic morcellator has been increasing over the past decade. Recently, we encountered a very rare case with a large parasitic myoma measuring 12 cm in diameter in the abdominal subcutaneous adipose tissue along an abdominal longitudinal surgical scar. The patient had twice undergone abdominal myomectomy for multiple fundal myomas. This is the first report describing a case with as large a parasitic myoma presenting in the suprafascial adipose tissue under the surgical scar after laparotomy. In such a case demonstrating a solid tumor of unknown cause after a gynecologic surgical procedure, a parasitic myoma must be included in the differential diagnosis.

Uterine cervical carcinomas associated with lobular endocervical glandular hyperplasia.

AIMS: To investigate the clinicopathological features of cervical uterine carcinoma associated with lobular endocervical glandular hyperplasia (LEGH). METHODS AND RESULTS: Subjects comprised 12 patients with cervical carcinoma associated with LEGH. Carcinoma included nine invasive adenocarcinomas, two adenocarcinoma in-situ (AIS) and one microinvasive squamous cell carcinoma (SCC). Baseline characteristics, cervical cytology, human papilloma virus (HPV) status, immunohistochemistry, surgical procedures and clinical outcomes were investigated. There was a pair of adenocarcinoma cases in a mother and daughter unrelated to Peutz-Jeghers syndrome. In all patients, atypical cells were seen on cervical cytology (adenocarcinoma cells in 11 cases and SCC cells in one). All the 12 patients were positive for mucin antigen 6 (MUC6) in the LEGH component, while seven patients were positive for gastric mucin (HIK1083). HPV was detected only in the SCC component. One patient with adenocarcinoma stage Ib died of disease 4 years after radical hysterectomy. The others are currently alive 2-16 years postoperatively. CONCLUSIONS: The diagnosis of adenocarcinoma with LEGH is not always difficult. The prognosis of adenocarcinoma associated with LEGH may be better than previously expected. Adenocarcinoma with a LEGH component does not always develop into a highly aggressive minimal deviation adenocarcinoma.

Fourteen-year-old girl with recurrent luteal-phase-dependent episodes of high fever.

Recurrent episodes of high fever during the luteal phase are exceedingly rare. A 14-year-old girl with a 1-year history of recurrent febrile episodes associated with the menstrual cycle was referred to our department. Febrile episode (39-41°C) occurred for 10 to 12 days concomitantly with the luteal phase of each ovulatory cycle. To suppress the ovulatory cycle, gonadotropin releasing hormone agonist was administered for 5 months, and then febrile attack disappeared (34.5-36.2°C). Before and during gonadotropin releasing hormone agonist therapy, serum levels of inflammatory cytokines (interleukin [IL]-1ß, IL-2, IL-6, IL-8, IL-10, and tumor necrosis factor-α) were unchanged and all of these were within the normal ranges. In our case, luteal-phase-dependent febrile episodes may not be attributable to the intervention of inflammatory cytokines as major fever mediators.

Relative contribution of weight-bearing and non-weight-bearing effect of adipose tissue to bone mineral density in postmenopausal women.

AIM: To investigate the relative contributions of weight-bearing and non-weight-bearing effects of adipose tissue to bone mineral density (BMD) in postmenopausal women. MATERIAL AND METHODS: The subjects were 228 postmenopausal women aged 50-75 years. Age, years since menopause (YSM), height, body weight, and body mass index were recorded. Trunk fat mass, body fat mass, bilateral leg BMD and lean (muscle) mass were measured by whole body scanning with dual-energy X-ray absorptiometry. The relationships of BMD to trunk and body fat mass were investigated using uni- and multivariable analyses. RESULTS: The amount of trunk fat mass and body fat mass were 8.7 ± 3.6 kg and 19.0 ± 5.9 kg, respectively. On Pearson's correlation test, right leg BMD was positively correlated with trunk fat mass (r=0.268, P<0.001) and body fat mass (0.299, P<0.001). On multiple linear regression analysis, trunk fat mass (t-value = 3.500, P<0.001), age (-2.431, P<0.05), and YSM (-2.564, P<0.01) were independent significant predictors of right leg BMD. However, body fat mass was not a predictor of BMD (-0.465, P=0.642). These relationships remained significant after further adjusting for right leg muscle mass. CONCLUSION: Trunk fat mass rather than body fat mass is a significant predictor of leg BMD at the most weight-bearing site, despite being less than half the amount of body fat mass. Thus, adipose tissue contributes more to BMD through non-weight-bearing effect rather than weight-bearing effect.

Clinical outcome of stage Ia1 squamous cell carcinoma of the uterine cervix and pathological findings of initial conization.

AIM: The present study investigated the clinical outcome of stage Ia1 squamous cell carcinoma (SCC) of the uterine cervix at a single institute. MATERIALS AND METHODS: Subjects were 84 patients with cervical SCC, International Federation of Gynecology and Obstetrics stage Ia1 diagnosed according to conization findings between January 2000 and June 2009. Correlations between clinical outcome and pathological findings on initial conization were investigated. RESULTS: Of 65 hysterectomy (without pelvic lymphadenectomy) patients, two (3.1%) showed metastasis to the vaginal wall, and two (3.1%) to the pelvic lymph nodes. Five patients (6.0%) showed lymphovascular invasion, and three (3.6%) showed confluent patterns of stromal invasion (confluent invasion) on initial conization findings. All of these five patients were included in the hysterectomy group. Of 19 patients with conization alone, two showed vaginal metastasis. Of four patients with vaginal metastasis, two showed lymphovascular invasion and one showed confluent invasion despite negative conization margin. In patients with nodal metastasis, stromal invasion of 3.0 mm and 2.8 mm, and horizontal spread of 6.8 mm and 6.9 mm were observed on conization, respectively. All patients are currently alive due to adequa\e therapy including chemo-radiation for six patients with recurrent disease. CONCLUSIONS: In patients showing stromal invasion of nearly 3.0 mm and horizontal spread of nearly 7.0 mm in stage Ia1 cervical SCC, pelvic lymphadenectomy may be considered. Even for patients showing a negative conization margin, careful follow up is necessary, because vaginal metastasis sometimes occurs.
