The pathogenesis and therapeutic treatment of intrauterine adhesions (IUAs) remain unsolved, highlighting the need for stable and effective experimental animal models. In this study, uterine electrocoagulation of twenty-one female New Zealand White rabbits was carried out to establish an IUA model. As rabbits have two completely separate uterine horns, each rabbit had its own internal control: one uterine horn was given an electrothermal injury (Group A, n=21), and the contralateral uterine horn received no treatment and served as the control (Group B, n=21). The endometrial morphology, number of endometrial glands, area of endometrial fibrosis, and number of implanted fetuses were compared between the two groups. In Group A, the numbers of endometrial glands on Days 7 and 14 and the number of implanted fetuses were significantly lower than those in Group B (P<0.05, P<0.05, and P<0.01, respectively), while the ratio of the area with endometrial stromal fibrosis to the total endometrial area was significantly increased (P<0.01). These results suggest that this method of electrothermal injury is effective for the establishment of a rabbit IUA model between 7 and 14 d after surgery.

OBJECTIVE: To assess actual rates of late vaginal stenosis and identify predisposing factors for complications among patients with previously untreated cervical cancer following high-dose-rate brachytherapy. METHODS: We performed longitudinal analyses of 57 patients using the modified Dische score at 6, 12, 18, 24, 36, and 60 months after treatment, which consisted of 15 interstitial brachytherapys and 42 conventional intracavitary brachytherapys, with a median follow-up time of 36 months (range, 6 to 144 months). RESULTS: More than half of the patients developed grade 1 (mild) vaginal stenosis within the first year of follow-up, and grade 2 (97.5%, moderate) to grade 3 (severe) stenosis gradually increased with time. Actual stenosis rates for grade 1, 2, and 3 were 97.5% (95% confidence interval [CI], 92.7 to 97.5), 60.7% (95% CI, 42.2 to 79.3), and 7.4% (95% CI, 0 to 18.4) at 3 years after treatment. Pallor reaction grade 2-3 at 6 months was only a statistically significant predisposing factor for grade 2-3 late vaginal stenosis 3 years or later with a hazard ratio of 3.48 (95% CI, 1.32 to 9.19; p=0.018) by a multivariate Cox proportional hazard model. Patients with grade 0-1 pallor reaction at 6 months showed a grade > or =2 vaginal stenosis rate of 53%, whereas the grade 2-3 pallor reaction group achieved a grade > or =2 vaginal stenosis rate at 3 years at 100% (p=0.001). CONCLUSION: High-dose-rate brachytherapy was associated with high incidence of late vaginal stenosis. Pallor reaction grade 2-3 at 6 months was predictive of late grade 2-3 vaginal stenosis at 3 years after treatment. These findings should prove helpful for patient counseling and preventive intervention.

In gynecology, endosalpingiosis is a benign condition in which the fallopian tube-like epithelium is found outside the fallopian tube. The thirty-four point five percent of endosalpingiosis cases have concurrent endometriosis and 40% of the endosalpingiosis group are in postmenopausal states. In contrast with endometriosis, there are no significant links between infertility, chronic pelvic pain and endosalpingiosis. The symptoms of endosalpingiosis are not yet settled. Endosalpingiosis is almost always an incidental finding; it is commonly found through microscopic examinations, and is then confirmed by pathologists for excision and biopsy. Therefore, the clinical differential diagnosis of an intramural mass is more important for clinicians when discussing further surgery with the patients. We report case of woman who has endosalpingiosis and is presented with vaginal bleeding. We first suspect the disease during physical examination. Under the impression of pelvic mass, laboratory tests and radiological images of contrast enhanced chest computer tomography are taken. Images show multisepted cystic masses in left adnexa. To rule out the pelvic mass, we executed exploratory laparotomy. Pathologic results show endosalpingiosis near the ovary section. But the endosalpingiosis, is not generally considered a pathology, and thus, no treatment is necessary.

OBJECTIVETo investigate the expression of suppressor of cytokine signaling(SOCS)-3 and caspase-3 and their correlative significance in endometriosis.
METHODSImmunohistochemical EnVision method was used to detect the SOCS-3 and caspase-3 protein expression in ectopic and eutopic endometrium (n = 32) of patients with endometriosis, as well as normal endometrium (n = 30) of women without endometriosis.
RESULTSSOCS-3 and caspase-3 proteins were expressed in all three groups and not affected by the menstrual cycles. The expression of SOCS-3 in ectopic endometrium (5.54 ± 2.12) was significantly lower than that in eutopic (7.39 ± 1.09, P = 0.001) and control group (7.48 ± 1.26, P < 0.01), but without difference between the eutopic and control group (P = 0.756). SOCS-3 expression in ectopic and eutopic endometrium was significantly lower in III/IV stages than that in I/II stages of endometriosis (P < 0.05). Significantly lower expression of caspase-3 protein was found in ectopic (3.20 ± 1.24) and eutopic endometrium (3.88 ± 1.93) as compared with the control group (6.49 ± 1.85, P < 0.01), however ectopic and eutopic endometrium showed no significant difference (t = 1.66, P = 0.10). There was no significant difference of the expression of caspase-3 in ectopic and eutopic endometrium at different disease stages (P > 0.05). Positive correlation was found between the expression of SOCS-3 and caspase-3 proteins in ectopic endometrium (r = 0.655, P < 0.01).
CONCLUSIONSOCS-3 may be involved in the development of endometriosis through inhibition of apoptosis of ectopic endometrial cells.

INTRODUCTIONWe aimed to evaluate the local incidences of hydronephrosis and renal impairment in the presence of severe uterovaginal or vault prolapse, and determine whether treatment by surgery or ring pessary resulted in the resolution of hydronephrosis in these patients.
METHODSThis was a retrospective case study of 121 patients who presented with severe uterovaginal or vault prolapse. All patients who had fourth degree uterovaginal or vault prolapse, and underwent renal ultrasonography and renal function blood tests were included in the study. Follow-up imaging for hydronephrosis was performed to determine the outcome after patients received treatment.
RESULTSThe mean age of the study population was 66.1 years. The overall incidence of hydronephrosis was 20.6%. The incidence of hydronephrosis in patients with severe vault prolapse was 7.1%, while that in patients with severe uterovaginal prolapse was 22.4%. Of the 25 patients with hydronephrosis, 16 (64.0%) had complete resolution of hydronephrosis after treatment, 5 (20.0%) had residual but smaller degrees of hydronephrosis, and 4 (16.0%) were lost to follow-up. The incidence of renal impairment was 3.3%.
CONCLUSIONThe local incidence of hydronephrosis in patients with severe uterovaginal or vault prolapse was 20.6% in our study. We established that 3.3% of women with severe uterovaginal or vault prolapse had mild renal impairment. Treatment by vaginal surgery for severe uterovaginal or vault prolapse appears to result in either complete resolution or improvement of hydronephrosis in the majority of patients.

Radiotherapy plays a major role in the treatment of cervical cancer. A successful radiotherapy program integrates both external beam and brachytherapy components. The principles of radiotherapy are strongly based on the anatomy of the organ and patterns of local and nodal spread. However, in patients with distorted anatomy, several practical issues arise in the delivery of optimal radiotherapy, especially with brachytherapy. Müllerian duct anomalies result in congenital malformations of the female genital tract. Though being very commonly studied for their deleterious effects on fertility and pregnancy, they have not been recognized for their potential to interfere with the delivery of radiotherapy among patients with cervical cancer. Here, we discuss the management of cervical cancer among patients with Müllerian duct anomalies and review the very sparse amount of published literature on this topic.

Singapore medical journal 2012;53(6):e114-6
Cervical stenosis is a challenging condition that often recurs despite intervention. Multiple therapeutic options have been described, but a clearly effective and reliable treatment method has yet to be identified. Patients with recurrent stenosis are at risk of developing severe complications such as chronic pelvic pain and infertility. We describe a case of congenital cervical stenosis with secondary haematometra in which repeated cervical dilatation, hysteroscopic canalisation and administration of medications to retard endometrial development were unsuccessful in relieving the obstruction and preventing re-accumulation of menstrual blood. Total hysterectomy was eventually mandated by spontaneous rupture of the haematometra.

OBJECTIVETo compare the efficacy, side effects and influence of two chemotherapy regimens, paclitaxel liposome combined with platinum and paclitaxel combined with platinum, on the survival rate in patients with cervical carcinoma receiving concurrent chemoradiotherapy.
METHODSOne hundred and sixty two cases with primary cervical carcinoma diagnosed and treated in the Jiangxi Maternal and Children Hospital between January 2008 and November 2009 were enrolled in this randomized controlled trial. Seventy one cases were included in the paclitaxel group and 91 in the paclitaxel liposome group. The chemotherapy doses were as followings: paclitaxel liposome and paclitaxel 135 mg/m(2); cisplatin 80 mg/m(2) or carboplatin AUC 4 - 6, repeated every 21 days for two or three times. Radical radiotherapy was given to both groups at the same time. The efficacy was evaluated by the tumor regression and the patients were followed-up for six months.
RESULTSThe overall response rates of paclitaxel group and paclitaxel liposome group were 90.1% and 89.0%, respectively (P > 0.05). The 1-year cumulative survival rate was 91.4% for the paclitaxel group and 89.2% for the paclitaxel liposom group (P > 0.05). The incidence rate of adverse effects such as rash, gastrointestinal toxicity, bone marrow suppression and muscle/joint pain in the paclitaxel liposome group was significantly lower than that in the paclitaxel group (P < 0.05), while there was no significant difference regarding the hair loss, liver damage, and peripheral neuritis (P > 0.05).
CONCLUSIONSPaclitaxel liposome plus platinum is a safe and effective therapeutic regimen for stage IIa-IV cervical carcinoma. However, the long-term efficacy of this regimen should be further observed.
