[PMID: 32688212 DOI: 10.1016/j.jpba.2020.113475] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/24/2020] [Revised: 07/07/2020] [Accepted: 07/10/2020] [Indexed: 02/02/2023]
Abstract
The roots of Rubia cordifolia L. (RCL) have become an important medicine for abnormal uterine bleeding (AUB) and hemorrhage syndrome in Traditional Asian medicine. However, the underlying mechanism and the material basis of RCL for treating AUB has not been fully elucidated. In this study, quantitative evaluation of quinones, systematic pharmacology and experimental verification were adopted. Firstly, the Disease-Ingredient-Target network was established by Cytoscape, which was consistent with 23 compounds and 47 target genes. The hub targets were discovered by Maximal Clique Centrality (MCC) method with Cytohubba plugins of Cytoscape, and top 20 nodes were ranked by MCC. It was assumed that mollugin is the main ingredient of RCL for treating AUB. Pathways on which RCL acted were obtained from observation of its biological functions, KEGG pathways and Reactome pathway enrichment analysis. The possible mechanism of RCL for treating AUB was revealed for improvment of the blood clotting system, blood circulation, arachidonic acid metabolism and inflammation. Then, a novel method for evaluating the quality of RCL was established, and the content of mollugin in RCL was the higher than others. Finally, pharmacologic experiments confirmed that RCL could improve the inflammation by inhibiting the activity of COX-2 and cPLA2 enzyme, ameliorate blood hypercoagulability by affecting coagulation cascade and fibrinolytic system. It was found that RCL inhibited the expression COX-2 and PAI-1 by reducing HIF-1α expression. The trend of each index of mollugin was consistent with that of RCL, indicating that it played an important role in RCL for treating AUB. The above results could provide a novel method for the quality evaluation of RCL and was expected to give us more important information regarding the use of RCL as a promising drug candidate for AUB, offering a fertility preserving medical, non-hormonal treatment choose for women with AUB.

Artaş G, Pala Ş, Kuloğlu T, Atilgan R, Yavuzkir Ş, Akyol A. The effects of sclerotherapy with 5% trichloroacetic acid on the cyst diameter and ovarian tissue in the rat ovarian cyst model. J OBSTET GYNAECOL 2018; 38:686-692. [PMID: 29564948 DOI: 10.1080/01443615.2017.1399991] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.2] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Indexed: 10/17/2022]
Abstract
The aim of this study was to compare the effects of only aspiration with aspiration and 5% trichloroacetic acid (TCA) application on ovarian cyst size and ovarian reserve. The ovarian cysts of 14 rats that were divided into two groups randomly were investigated after total salpingectomy procedure. G1 was the group of saline application after cyst aspiration, while in G2, after aspiration 5% TCA at half amount of aspiration volume was injected into the cyst and re-aspirated after five minutes. The abdomens of the rats were closed and re-explored after 1 month. The cyst diameters of the rats in each group were measured. Ovaries were removed for histopathological examination. There was no significant difference in cyst diameter in G1 before and after aspiration. In G2, there was a significant decrease in cyst size after TCA application. Ovarian follicle counts were not significantly different between the two groups. In conclusion, application of 5% TCA to the ovarian cysts for five minutes significantly reduces the cyst size. Impact Statement What is already known on this subject: Minimally invasive therapies come into prominence to avoid surgical complications and diminished fertility in the treatment of ovarian cysts. USG-guided aspiration and sclerosis has been reported as cost-efficient and effective treatment methods for localised benign cysts in other organs such as the thyroid, parathyroid, liver, kidney and spleen. It has been shown that sclerotherapy applied to infertile women with ovarian cysts reduces pelvic pain without affecting the number of follicles, term pregnancy and abortion rates, extracted oocytes, embryo quality or hormonal levels when compared to non-ovarian cystic infertile women. TCA is a chemical agent that is topically applied, not systemically absorptive, which causes denaturation of proteins and structural cell death, resulting in coagulation necrosis after chemical cauterisation. For this reason, we used 5% TCA to treat simple ovarian cysts on a rat model. What the results of this study add: In this experimental study, we showed that the application of 5% TCA into the cyst for five minutes - then aspirated - significantly reduced the size of the ovarian cysts. Five percent TCA application did not affect the ovarian reserve. What the implications are of these findings for clinical practice and/or further research: Our study is original because of the fact that to the best of our knowledge, this is the first study about the use of 5% TCA in treatment of ovarian cysts in the literature.

Abstract
Pilomatricomas are benign calcifying neoplasms derived from follicle matrix cells. Standard treatment for pilomatricomas involves complete surgical excision, with an overall low rate of recurrence. We discuss a simple alternative surgical technique that allows for removal of the lesion with less residual defect than complete excision.

Abdellah MS, Elsaman AMMM. Trichloroacetic acid for the treatment of dysfunctional uterine bleeding: a pilot prospective clinical trial. Eur J Obstet Gynecol Reprod Biol 2012; 165:280-3. [PMID: 22841653 DOI: 10.1016/j.ejogrb.2012.07.003] [Citation(s) in RCA: 3] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/01/2012] [Revised: 06/04/2012] [Accepted: 07/01/2012] [Indexed: 11/16/2022]
Abstract
OBJECTIVE The aim of the trial was to assess the safety and efficacy of tricholoroacetic acid for the treatment of dysfunctional uterine bleeding using topical versus intrauterine instillation. STUDY DESIGN In a pilot prospective randomized clinical trial, seventy women were randomly allocated to one of two groups. In Group I, the patients were subjected to intrauterine instillation of 95% tricholoroacetic acid. Group II underwent dilatation and curettage before topical application of 95% tricholoroacetic acid. RESULTS The groups were similar regarding baseline clinical characteristics. There was a satisfactory clinical reduction of menstrual flow (amenorrhea, hypomenorrhea and eumenorrhea) at a rate of 97.1% (Group I) and 85.7% (Group II) at 6 months. A significant increase was observed in the mean haemoglobin value at 3 and 6 months in both treatment groups (P<0.05). Group I showed a significant increase in haemoglobin level compared to Group II (P<0.05) and a significant reduction of the endometrial thickness compared to Group II (2.21 ± 0.41 versus 3.03 ± 3.37). CONCLUSION Trichloroacetic acid use for treating dysfunctional uterine bleeding seems to be efficient and safe, especially in women who do not require conception. Trichloroacetic acid intrauterine instillation is associated with longer duration of reduced menstrual bleeding than topical application.

Abstract
OBJECTIVE To develop an animal model of endometrial ablation, and to evaluate the histologic effects of trichloroacetic acid (TCA) in the uterine cavity. DESIGN Experimental prospective. SETTING Department of gynecology. PATIENT(S) Thirty female adult rats. INTERVENTION(S) Animals were submitted to injection of TCA in one uterine horn and saline solution in the other. Group 1 was sacrificed the day after the procedure. Group 2 was sacrificed in phase of diestrus. Superficial epithelia of the endometrium, stromal thickness, endometrial glands, and myometrium thickness were compared among the uterine horns of the same rats of group 1. The same evaluation was performed in group 2. Endometrial regeneration was evaluated. MAIN OUTCOME MEASURE(S) Histologic effects. RESULT(S) In group 1, histologic parameters showed endometrial destruction on TCA injected uterine horn. In group 2, four rats died after the procedure, and six rats had no viable material. In the rest of the group, TCA-injected uterine horns showed endometrial destruction. Superficial epithelia of the endometrium and stromal thickness were similar between TCA uterine horn from groups. However, the number of endometrial glands was higher in group 1. CONCLUSION(S) The study developed an experimental model for endometrial ablation. TCA acid is a potent agent for endometrial ablation in rat model. No endometrial regeneration was observed after recovery of cycle.

Abstract
PURPOSE In this study, we sought to 1) describe elements of the financial and quality-of-life burden of dysfunctional uterine bleeding (DUB) from the perspective of women who agreed to obtain surgical treatment; 2) explore associations between DUB symptom characteristics and the financial and quality-of-life burden; 3) estimate the annual dollar value of the financial burden; and 4) estimate the most that could be spent on surgery to eliminate DUB symptoms for which medical treatment has been unsuccessful that would result in a $50,000/quality-adjusted life-year incremental cost-effectiveness ratio. METHODS We collected baseline data on DUB symptoms and aspects of the financial and quality-of-life burden for 237 women agreeing to surgery for DUB in a randomized trial comparing hysterectomy with endometrial ablation. Measures included out-of-pocket pharmaceutical expenditures, excess expenditures on pads or tampons, the value of time missed from paid work and home management activities, and health utility. We used chi2 and t tests to assess the statistical significance of associations between DUB characteristics and the financial and quality-of-life burden. The annual financial burden was estimated. RESULTS Pelvic pain and cramps were associated with activity limitations and tiredness was associated with a lower health utility. Excess pharmaceutical and pad and tampon costs were $333 per patient per year (95% confidence interval [CI], $263-$403). Excess paid work and home management loss costs were $2,291 per patient per year (95% CI, $1847-$2752). Effective surgical treatment costing $40,000 would be cost-effective compared with unsuccessful medical treatment. CONCLUSION The financial and quality-of-life effects of DUB represent a substantial burden.

Abstract
Both hysterectomy for heavy menstrual bleeding and radical mastectomy for breast cancer are steeped in the history of surgery and have recently been challenged as being too radical for the disorder at hand. Radical mastectomy has largely been replaced with local removal of the tumor with subsequent radiation and/or chemotherapy. Alternatives to hysterectomy include a number of medical interventions, most notably intrauterine progestin-releasing systems, and endometrial ablation, a procedure that has a relatively high success rate and one that is now feasible for many women in an office or procedure room setting. However, although radical mastectomy rates have dropped precipitously, hysterectomy rates, at least in the United States remain relatively stable. Determining the proportion of hysterectomies that are done for heavy menstrual bleeding is difficult, largely because of coding issues, so it is difficult to measure the impact of new medical and minimally invasive surgical procedures. Nevertheless, it seems clear that many women are not exposed to the plethora of options to hysterectomy, a fact that may reflect a number of issues that may include training, skill, and financial incentives or disincentives. Clearly, options to hysterectomy are not a panacea, but if women are empowered to select from all of the options available, the rate of hysterectomy for bleeding should decrease while maintaining, or even enhancing the patient's satisfaction with care.

Abstract
An estimated 10%-30% of menstruating women experience menorrhagia at some time during their reproductive lives. Acute menorrhagia may present as an emergency requiring prompt medical or surgical intervention. Chronic menorrhagia affects a woman's quality of life in her work, family, and social interactions. Medical management is the first line of therapy for chronic menorrhagia. Agents that have been used to treat menorrhagia include iron, cyclooxygenase inhibitors, desmopressin, antifibrinolytics, gonadotropin-releasing hormone agonists, androgens, combined oral contraceptives, and progestins. Progestins can be administered systemically or locally and may be given cyclically or continuously. Increased use of effective medical therapies has the potential to reduce the number of surgical procedures, such as endometrial ablation and hysterectomy.

Abstract
Endometrial ablation (EA) is targeted destruction of the endothelial surface of the uterine cavity. The procedure was originally designed as a less invasive alternative to hysterectomy for the symptom of heavy menstrual bleeding unrelated to structural pathology of the uterus, that was not responsive to medical therapy. More recently it has become apparent that the procedure can be performed in the presence of submucous leiomyomas, providing they meet a number of size and location criteria. The first EA serie as published in Germany in the 1930s, but the procedure did not attract much attention until the latter part of the 20th century. Currently, EA can be performed under endoscopic direction with the neodymium:yttrium alumnum garnet laser, with a radiofrequency resectoscope, or with an expanding array of nonresectoscopic EA systems. It is apparent that most but not all of the complications associated with resectoscopic endometrial ablation are eliminated with nonresectoscopic endometrial ablation, but serious morbidity has been reported with all of the newer systems to date. Success and patient satisfaction seem to be enduring in the majority of well-selected patients treated in clinical trials, but repeat surgery, usually hysterectomy, is performed in 25% to 40% by 5 years after surgery. Increased efficiencies should be realized if the procedure could be moved to an office setting.

Abstract
PURPOSE OF REVIEW This review evaluates the currently available evidence regarding resectoscopic endometrial ablation (REA) and the various nonresectoscopic endometrial ablation (NREA) techniques used for heavy menstrual bleeding. RECENT FINDINGS Laser endometrial ablation is now used infrequently, largely because of procedure time, but also because of the cost and training associated with the technique. REA can be performed in a wider spectrum of endometrial cavity configurations than NREA and, at least in expert hands, remains the gold standard. Each of the five available types of NREA device possesses advantages and disadvantages over the others with respect to variables such as treatment time, required cervical dilation, and size and configuration of the endometrial cavity. All provide acceptable results that are comparable to that of REA in expert hands. Serious complications seem to be less common with NREA, but uterine perforation and bowel or other visceral injury can still occur. When endometrial-ablation patients were followed for up to 5 years, repeat surgery rates ranged from 20 to 40%, thereby eroding both the direct and indirect treatment-related resource utilization. Levonorgestrel-releasing intrauterine devices demonstrate similar clinical and patient-satisfaction outcomes to endometrial ablation but can be inserted in the office and allow maintenance of fertility. SUMMARY Both REA and NREA provide at least short- to intermediate-term options to hysterectomy for patients with heavy menstrual bleeding and normal or near-normal endometrial cavities. Consequently, the ideal candidates are likely those who are within 5 years of menopause.
