A rare massive presentation of catamenial hemothorax

Catamenial hemothorax is a rare manifestation of thoracic endometriosis syndrome. It is commonly seen associated with pelvic endometriosis in nulliparous reproductive-age women. Most cases are minor and self-limiting. We present a case of a 32-year-old woman who presented with prolonged worsening dyspnea and was found to have a massive hemothorax on evaluation.     

酪氨酸激酶受体RON与E-cadherin在子宫内膜异位症上的表达及意义

目的探讨酪氨酸激酶受体RON及上皮型钙粘蛋白(E-cadherin)在子宫内膜异位症(endometriosis,EMs)上的表达及意义。方法选择2017年7~12月深圳市龙岗区人民医院收治的42例EMs患者,术中分别留取新鲜异位内膜组织和在位内膜组织,随机选取子宫切除或诊断性刮宫治疗的非EMs患者42例,术中留取其正常子宫内膜组织。采用逆转录聚合酶链反应(RT-PCR)检测子宫内膜组织中RON mRNA的表达,采用免疫组织化学方法检测对应42例石蜡组织中RON蛋白和E-cadherin的表达,并分析RON蛋白和E-cadherin的相关性。结果EMs异位内膜组织RON mRNA及RON蛋白阳性表达率显著高于在位内膜组织及正常子宫内膜组织(P<0.001),在位内膜组织及正常内膜组织中E-cadherin阳性表达率显著高于异位内膜组织(P<0.001),且异位内膜组织中RON mRNA及RON蛋白的表达与临床分期有关(P<0.001)。在同一标本中RON蛋白和E-cadherin表达呈负相关关系(r=-0.497,P<0.05)。结论RON的过度表达与EMs的发生发展密切相关,联合检测RON和E-cadherin的异常对判断EMs的发生发展有一定的参考价值,RON可能成为诊断治疗EMs的新靶点。     

Clinical analysis of high-intensity focussed ultrasound ablation for abdominal wall endometriosis: a 4-year experience at a specialty gynecological institution

Objective: To evaluate the long-term clinical effect of high-intensity focussed ultrasound (HIFU) as a non-invasive modality for ablation of abdominal wall endometriosis (AWE) foci.

Methods: All women who were diagnosed with cutaneous endometriosis and underwent HIFU ablation and 4-year follow-up were included. Patient symptoms, imaging performed, HIFU ablation, recurrence, lesion location, size and number were collected and analyzed.

Results: A total of 51 women with 57 painful abdominal wall masses with a median volume of 4.00?cm³ and a mean age of 30.5±2.12 years were treated with HIFU. The main symptoms were a palpable painful abdominal mass (93%), protrusion of the skin (28.1%, 16) or lack of protrusion of the skin (71.9%, 41). Ultrasound was initially performed in 100% (51) of women, whereas 6% (3) required MRI examinations to distinguish the features and range of the masses. Ablation was performed with a median 300?s of sonication time, 40?min treatment time, 150?W of power and 41800?J of total energy to treat lesions that were a median volume of 3.83?cm³. No severe complications occurred, except in one patient with a first-degree skin burn, during the 48-month follow-up period. The pooled recurrence of cutaneous endometriosis occurred in 3.9% (2) of women.

Conclusion: The diagnosis of AWE should be confirmed with imaging of the lesion number, location, size and features before HIFU ablation. HIFU should be the first choice for the treatment of AWE as it is a non-invasive method, with high efficiency and safety and rapid postoperative recovery.     

Proteases and their inhibitors as prognostic factors for high-grade serous ovarian cancer

Ovarian carcinoma is one of the most lethal malignancies, but only very few prognostic biomarkers are known. The degradome, comprising proteases, protease non-proteolytic homologues and inhibitors, have been involved in the prognosis of many cancer types, including ovarian carcinoma. The prognostic significance of the whole degradome family has not been specifically studied in high-grade serous ovarian cancer. A targeted DNA microarray known as the CLIP-CHIP microarray was used to identify potential prognostic factors in ten high-grade serous ovarian cancer women who had early recurrence (<1.6 years) or late/no recurrence after first line surgery and chemotherapy. In women with early recurrence, we identified seven upregulated genes (TMPRSS4, MASP1/3, SPC18, PSMB1, IGFBP2, CFI – encoding Complement Factor I – and MMP9) and one down-regulated gene (ADAM-10). Using immunohistochemistry, we evaluated the prognostic effect of these 8 candidate genes in an independent cohort of 112 high-grade serous ovarian cancer women. Outcomes were progression, defined according to CA-125 criteria, and death. Multivariate Cox proportional hazard regression models were done to estimate the associations between each protein and each outcome. High ADAM-10 expression (intensity of 2–3) was associated with a lower risk of progression (adjusted hazard ratio (HR): 0.51; 95% confidence interval (CI): 0.29-0.87). High complement factor I expression (intensity 2–3) was associated with a higher risk of progression (adjusted HR: 2.30, 95% CI: 1.17–4.53) and death (adjusted HR: 3.42; 95% CI: 1.72–6.79). Overall, we identified the prognostic value of two proteases, ADAM-10 and complement factor I, for high-grade serous ovarian cancer which could have clinical significance.     

Hiperplasia endotelial papilar intravascular (tumor Masson) de localización ginecológica

Intravascular papillary endothelial hyperplasia or Masson's tumour is a non-neoplastic vascular lesion of reactive character. It is a rare diagnosis, clinically non-specific and with diverse locations. It is essential to take it into consideration and make a differential diagnosis with malignant vascular tumours such as angiosarcoma. Pathological study is fundamental for diagnosis. Treatment consists of complete resection of the tumour, including sufficiently wide margins to avoid recurrence.The case reported is an exceptional event, because of the pelvic location of the Masson's tumour that was diagnosed as part of the surgical staging of an ovarian cancer.     

Systematic review of acceptability,cardiovascular, neurological,bone health and HRT outcomes following risk reducing surgery in BRCA carriers

Primary surgical prevention in the form of risk-reducing salpingo-oophorectomy (RRSO) is the most effective option and the gold standard for ovarian cancer (OC) risk-reduction, particularly given the absence of an effective national OC screening programme. However, premenopausal RRSO leads to premature surgical menopause with detrimental long-term health sequelae particularly in women who do not/are unable to take hormone replacement therapy (HRT). HRT uptake in women undergoing pre-menopausal oophorectomy appears low and is dependent on informed counselling, the safety of HRT and efficacy in mitigating the health sequelae of premature menopause. Acceptance of a central role for the fallopian tube in OC etiopathogenesis, coupled with the detrimental consequences of premature menopause, has led to the attractive proposal of early-salpingectomy with delayed oophorectomy as an alternative OC surgical prevention strategy in premenopausal women who have completed childbearing but decline or wish to delay RRSO. The successful implementation of risk reducing surgery for OC prevention depends on the acceptability of surgery to both, recipients (e.g. BRCA1/BRCA2 carriers) and intervention deliverers (healthcare professionals/researchers). Acceptability is also informed by an understanding of health outcomes following risk reducing surgery and the safety of HRT. It is therefore vital to understand the effects of surgery on important health outcomes such as cardiovascular health, neurological function and bone health. We present a comprehensive review of acceptability, the selected health outcomes mentioned above and HRT safety following risk reducing surgery.     

Study on therapeutic mechanism of Neiyifang in treating endometriosis

Objective: To observe the clinical effect of Neiyifang (NYF) in treating endometriosis and to explore its therapeutic mechanism through observing its influence on plasma β-endorphin (β-EP) in different menstrual stages and levels of prostaglandins (PGs) in menstruation.Methods:NYF was administered to 104 patients with endometriosis one dose daily with 3 successive menstrual cycles as one therapeutic course. Peripheral blood β-EP level in follicular, luteal and menstrual stages, as well as PGF_2α, PGE2, thromboxane B₂ and 6-keto-PGFl α levels in menstrual stage were detected by RIA, and controlled with those in 15 healthy persons.Results: (1) The total effective rate of NYF was 81.3% and it showed significant effect in improving patients’ clinical symptoms and physical signs; (2) In menstrual stage, the levels of β-EP, 6-keto-PGF_α/ TXB₂ were lower(P <0.05) and levels of PGF_2α, PGE₂, TXB₂ and 6-keto-PGF_1α were higher (P< 0. 05) in patients than those in control, and the higher the level of PGE₂, the severer the menalgia, (3) NYF could increase levels of β-EP, 6-keto-PGF_1α, and reduce levels of PGF_2α, PGE_2α in menstrual stage of patients (all P<0.05).Conclusion: (1) NYF has good clinical effect in treating endometriosis; (2) Patients’ symptom of menalgia is closely related with the excessive high levels of PGF_2α and PGE₂, PGI₂/TXA₂ ratio disturbance, and excessive low level of β-EP; (3) NYF could significantly decrease the PGE₂, PGF_1α levels, increase the 6-keto-PGF_1α/TXB₂ ratio and the level of β-EP, so as to alleviate the menalgia in patients with endometriosis.
