Yang Y, Wang Y, Huang Y, Song J, Ma X. Interceed combined with bone marrow mesenchymal stem cells improves endometrial receptivity of intrauterine adhesion. Regen Ther 2024; 27:445-454. [PMID: 38706569 PMCID: PMC11066143 DOI: 10.1016/j.reth.2024.04.007] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/04/2024] [Revised: 03/21/2024] [Accepted: 04/11/2024] [Indexed: 05/07/2024] Open
Abstract
Background This study aimed to investigate the impact of intrauterine adhesions (IUA) therapy and endometrial receptivity by implanting autologous bone marrow mesenchymal stem cells (BMSCs) into the Interceed and subsequently placing them in the uterine cavity of rats. Methods Fifty rats were divided into 5 groups according to the random number table method (10 rats in each group). Following the development of the IUA model through mechanical injury, the animals were categorized into different treatment groups: the IUA model (intrauterine perfusion of saline), Interceed therapy (intrauterine placement of Interceed), BMSCs therapy (intrauterine perfusion of BMSCs), BMSCs + Interceed therapy (intrauterine placement of BMSCs + Interceed), and a control group (intrauterine perfusion of saline). The Hematoxylin-eosin (HE) staining technique was employed to identify and assess the pathological alterations in the endometrium. Additionally, it facilitated the quantification of endometrial glands and the determination of endometrial thickness. Masson staining was used to detect fibrosis in rat uterus. The number of microvascular density (MVD) was detected by immunohistochemistry (IHC). Real-time quantitative reverse transcription polymerase chain reaction (qRT-PCR) and Western blot were used to detect the levels of leukemia inhibitory factor (LIF), integrin ανβ3, and vascular endothelial growth factor (VEGF) in uterine tissue. Male and female rats were combined in cages for reproductive and conception evaluation. Results In comparison to the control, the number of endometrial glands in the IUA model was significantly reduced, and the degree of endometrial thinning and fibrosis was significantly increased (p < 0.05). Compared with the IUA model, the number of endometrial glands did not exhibit any significant alterations in endometrial thickness and MVD number. The expressions of LIF, integrin ανβ3, and VEGF in the uterine tissue were not significantly improved with Interceed therapy, resulting in no significant improvement in the pregnancy rate (p > 0.05). The number of endometrial glands, endometrial thickness, and MVD in the BMSCs therapy group were significantly increased. Moreover, the expressions of LIF, integrin ανβ3, and VEGF in uterine tissue exhibited a significant increase, leading to a comparatively higher pregnancy rate (p < 0.05). In the BMSCs + Interceed therapy group, the number of endometrial glands, endometrial thickness, and MVD were significantly increased, and the expressions of LIF, integrin ανβ3, and VEGF in uterine tissue were significantly increased as well, along with a corresponding rise in the pregnancy rate (p < 0.05). Conclusion The intrauterine placement of Interceed combined with BMSCs in IUA rats can thicken the damaged endometrium, increase the number of glands, promote endometrial angiogenesis, improve endometrial receptivity, and increase the rate of pregnancy in IUA rats.

Luo Y, Sun Y, Huang B, Chen J, Xu B, Li H. Effects and safety of hyaluronic acid gel on intrauterine adhesion and fertility after intrauterine surgery: a systematic review and meta-analysis with trial sequential analysis of randomized controlled trials. Am J Obstet Gynecol 2024:S0002-9378(24)00007-3. [PMID: 38191020 DOI: 10.1016/j.ajog.2023.12.039] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/06/2023] [Revised: 12/19/2023] [Accepted: 12/28/2023] [Indexed: 01/10/2024]
Abstract
OBJECTIVE This study aimed to determine the efficacy and safety of hyaluronic acid gel for the prevention of intrauterine adhesions and improved fertility after intrauterine surgery. DATA SOURCES PubMed, EMBASE, Cochrane Library, Web of science, and ClinicalTrials.gov were searched up to November 1, 2023. STUDY ELIGIBILITY CRITERIA Randomized controlled trials that reported intrauterine adhesion and fertility outcomes among women who used hyaluronic acid after intrauterine surgery. METHODS The risk of bias was assessed using criteria of the Cochrane Handbook, and the quality of the evidence was evaluated using the Grades of Recommendation, Assessment, Development, and Evaluation system. The Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines were followed. A trial sequential analysis was conducted to assess the outcomes, and Stata 14 was used for sensitivity analyses and publication bias analyses. RESULTS Data from 16 randomized controlled trials involving 2359 patients were extracted and analyzed. The analysis revealed that hyaluronic acid reduced the incidence of intrauterine adhesion (risk ratio, 0.53; 95% confidence interval, 0.42-0.67; I2=48%) and improve pregnancy rates (risk ratio, 1.24; 95% confidence interval, 1.02-1.50; I2=0%). A subgroup analysis was conducted to evaluate factors that influence the effect of hyaluronic acid on the incidence of intrauterine adhesion. It was found that a small volume of hyaluronic acid reduced the incidence of intrauterine adhesions. Hyaluronic acid exhibited a protective effect among patients who underwent various intrauterine surgeries and who had different gynecologic medical histories. The protective effect was statistically significant after a follow-up of 6 to 12 weeks. The results of the trial sequential analysis indicated that the effect of hyaluronic acid on the incidence of mild intrauterine adhesions, pregnancy rates, live birth rates, and miscarriage rates after intrauterine surgery may be inconclusive and thus further evaluation is required in the form of additional clinical trials. However, the remaining effects were found to be verifiable and did not require more clinical trials for confirmation. CONCLUSION Hyaluronic acid can safely and effectively reduce the incidence of intrauterine adhesions and may improve fertility outcomes.

Abstract
Two international guidelines published on the management of Asherman syndrome (AS) have made recommendations on various adjuvant methods to prevent intrauterine reformation. Nevertheless, the effectiveness of these methods when used in primary or secondary prevention settings is different. Our aim is to assess the effectiveness of various adjuvant methods for the secondary prevention of intrauterine adhesions (IUAs). Articles were considered eligible if they included subjects with AS before surgery and compared a chosen method with either a control or a comparison group (using another method). The primary outcome was the IUA reformation rate at follow-up hysteroscopy. A total of 29 studies [15 randomised controlled trials (RCTs) and 14 cohort studies] were included. Adhesion reformation with various methods to prevented IUA reformation when compared with controls were: second-look hysteroscopy: [risk ratio (RR): 0.21, 95% confidence interval (CI): 0.05-0.90 (p = 0.02)]; intrauterine contraceptive device: RR: 0.64, 95% CI: 0.36-1.12 (p = 0.12); continuous intrauterine balloon: RR: 0.18, 95% CI: 0.05-0.68 (p = 0.01); intermittent intrauterine balloon: RR: 0.50, 95% CI: 0.31-0.80 (p = 0.004); anti-adhesion gel: RR: 0.80, 95% CI: 0.58-1.10 (p = 0.17); amnion graft: RR: 0.63, 95% CI: 0.44-0.91 (p = 0.01).

Abstract
We evaluated the clinical outcomes of using type 1 collagen gel after therapeutic resectoscopy; overall, 150 women aged > 20 who planned to undergo therapeutic resectoscopy were enrolled. The patients were randomly assigned to either of the anti-adhesive treatment groups: the type 1 collagen gel (Collabarrier®) (study group; N = 75) or the sodium hyaluronate and sodium carboxymethylcellulose gel group (control group; N = 75) after resectoscopy. One month after applying anti-adhesive materials, postoperative intrauterine adhesions were evaluated using second-look hysteroscopy; the incidence rate of postoperative intrauterine adhesions examined through second-look hysteroscopy showed no significant differences between the groups. There were no statistical differences between the frequency and mean scores of the type and intensity of adhesions in both groups. Finally, no significant differences in adverse events, serious adverse events, adverse device effects, and serious adverse device effects were noted between the two groups; type 1 collagen gel can be effectively and safely used in intrauterine surgery to minimize postoperative adhesions, thereby eventually decreasing the prevalence of infertility, secondary amenorrhea, and recurrent pregnancy loss in reproductive women.

Abstract
Postoperative adhesion, bonding of the abdominal wall to damaged organs, causes severe complications after abdominal surgery. Despite the availability of physical barriers (i.e., solutions, films, and hydrogels), adhesion prevention materials that are a single-substance system with stability in wet tissue and ease of use have not been reported. Here, we report a microparticle based, sprayable adhesion prevention material comprising decyl group modified Alaska pollock gelatin (C10-ApGltn). C10-ApGltn microparticles (C10-MPs) were prepared by a coacervation method, freeze drying, and thermal crosslinking. The C10-MPs adhered to and formed a colloidal gel layer on intestinal serosal tissue by hydration without any crosslinking agents. After hydration of the C10-MPs, the resulting colloidal gel layer did not adhere to other tissues. Additionally, the C10-MP colloidal gel layer formed on the stomach serosal tissue showed stability when submersed in saline for 2 days. The colloidal gel layer also showed tissue followability. An in vivo rat adhesion model revealed that C10-MP colloidal gel layer on the cecum and abdominal wall defects effectively reduced postoperative adhesion and induced tissue remodeling, including re-mesothelialization. Therefore, C10-MPs are a potential anti-adhesion material for preventing postoperative adhesion. STATEMENT OF SIGNIFICANCE: We evaluated the postoperative adhesion prevention ability of a colloidal gel based on decyl group modified Alaska pollock gelatin (ApGltn) microparticles (C10-MPs). These microparticles are sprayable and form a colloidal gel with only hydration on the gastrointestinal tissue. We revealed that the modification of the decyl group into ApGltn improved the stability of C10-MP colloidal gel on the tissue by hydrophobic interaction in the in-vitro experiments. The gel prevented postoperative adhesion by being a physical barrier in the in-vivo rat adhesion model.

Abstract
Herein, we designed and fabricated a biodegradable composite sponge which main component contained N, O-carboxymethyl chitosan (N,O-CS) and oxidized cellulose nanocrystals (TOCN) as a potential wound dressing for the prevention and treatment of postoperative adhesion. In order to improve antimicrobial properties of N,O-CS/TOCN composite sponges, natural antimicrobial agents (ε-Poly-l-Lysine,EPL) were successfully introduced and the EPL/N,O-CS/TOCN composite sponge exhibited excellent antibacterial properties and biological security. The EPL/N,O-CS/TOCN composite sponge can be degraded in vivo within 3 weeks. Finally, we analyzed the anti-adhesion performance of EPL/N,O-CS/TOCN composite sponge through a rat model of sidewall defect-cecum abrasion. These results demonstrated that EPL/N,O-CS/TOCN-treated group can effectively reduce the peritoneal adhesion formation than the commercial soluble gauze group and normal saline group, which mainly attribute to the excellent hemostatic function and tissue repair function of EPL/N,O-CS/TOCN composite sponge. It is believed that the EPL/N,O-CS/TOCN composite sponge will prove to be as a new medical device treat the internal tissue/organ repair and simultaneous prevention of postoperative adhesion.

Strangulated small bowel obstruction caused by isolated obturator nerve and pelvic vessels after pelvic lymphadenectomy in gynecologic surgery: two case reports. Surg Case Rep 2022; 8:104.

Abstract
Abstract
Background
Although small bowel obstruction (SBO) is a major complication occurring after abdominal surgery, few reports have described strangulated SBO after pelvic lymphadenectomy (PL). This report describes two cases of strangulated SBO caused by a skeletonized obturator nerve and pelvic vessels after laparoscopic PL during gynecologic surgery.
Case presentation
Case 1: A 57-year-old woman with endometrial cancer underwent a laparoscopic semi-radical total hysterectomy with PL. Nine months after the operation, she visited our emergency room complaining about subacute pain spreading in the right groin, right buttock, and dorsal part of the right thigh. She had no abdominal pain. Although her symptoms were not typical, computed tomography (CT) revealed strangulated SBO in the right pelvis. Laparoscopic surgery revealed that the small bowel was ischemic. Then we converted to open surgery. We transected the right obturator nerve and umbilical artery, which constructed an internal hernia orifice in the right pelvis, followed by resection of the ischemic small bowel. Fortunately, during 6-month follow-up, she showed only slight difficulty in walking as a postoperative complication. Case 2: A 62-year-old woman with cervical cancer underwent laparoscopic radical hysterectomy with PL. Six months after the operation, she visited our hospital emergently because of sudden onset of abdominal pain and vomiting. CT showed strangulated SBO. Urgent laparoscopic surgery exhibited the incarcerated small bowel at the right pelvis. Consequently, we converted to open surgery. The terminal ileum was detained into the space constructed by the right umbilical artery. We cut the umbilical artery and performed ileocecal resection. After the surgery, she was discharged with no complication or sequela.
Conclusion
When examining a patient after PL who complains of severe pain or symptoms, one should consider the possibility of PL-related SBO, even if the pain is apparently atypical for SBO.

Abstract
PURPOSE Treatment of Asherman syndrome (AS) presents a significant clinical challenge. Based on our in vitro data showing that PRP could activate endometrial cell proliferation and migration, we hypothesized that intrauterine infusion of autologous platelet-rich plasma (PRP) may improve endometrial regeneration and fertility outcomes in patients with moderate-severe AS. MATERIALS AND METHODS Subjects with moderate-severe AS were randomized to PRP or saline control administered following hysteroscopic adhesiolysis. Due to relative inability to randomize patients to the control group, after initial randomization of 10 subjects (6 in PRP and 4 in control groups), the remainder were prospectively enrolled in PRP group (n = 9), with 11 historic controls added to control group, for a total of 30 subjects (PRP n = 15; saline control n = 15). Right after hysteroscopy, 0.5-1 mL of PRP or saline was infused into the uterus via a Wallace catheter, followed by estrogen therapy. The primary outcomes were changes in endometrial thickness (EMT, checked in 3 weeks) and in menstrual flow; secondary outcomes were pregnancy and live birth rates. EMT and menstrual bleeding pattern were assessed before and after the intervention. Pregnancy was assessed over a 6-month period. RESULTS There were no statistically significant differences in age, gravidity/parity, cause of AS, preoperative menses assessment, AS hysteroscopy score, and intrauterine balloon placement between the groups. There was no statistically significant difference (p = 0.79) in EMT pre-PRP infusion for control (5.7 mm, 4.0-6.0) and study arm (5.3 mm, 4.9-6.0). There was no statistically significant change (p = 0.78) in EMT after PRP infusion (1.4 mm, - 0.5-2.4) vs saline (1.0 mm, 0.0-2.5). Patients tolerated the procedure well, with no adverse effects. There was no difference in the predicted likelihood of pregnancy (p = 0.45) between the control (0.67, 0.41-0.85) and study arm (0.53, 0.29-0.76). CONCLUSIONS PRP was well accepted and tolerated in AS patients. However, we did not observe any significant EMT increase or improved pregnancy rates after adding PRP infusion, compared to standard treatment only. The use of intrauterine PRP infusion may be a feasible option, and its potential use must be tested on a larger sample size of AS patients.

[PMID: 34356652 PMCID: PMC8301806 DOI: 10.3390/biom11071027] [Citation(s) in RCA: 32] [Impact Index Per Article: 10.7] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/06/2021] [Revised: 07/06/2021] [Accepted: 07/07/2021] [Indexed: 02/06/2023] Open
Abstract
Post-operative adhesions affect patients undergoing all types of surgeries. They are associated with serious complications, including higher risk of morbidity and mortality. Given increased hospitalization, longer operative times, and longer length of hospital stay, post-surgical adhesions also pose a great financial burden. Although our knowledge of some of the underlying mechanisms driving adhesion formation has significantly improved over the past two decades, literature has yet to fully explain the pathogenesis and etiology of post-surgical adhesions. As a result, finding an ideal preventative strategy and leveraging appropriate tissue engineering strategies has proven to be difficult. Different products have been developed and enjoyed various levels of success along the translational tissue engineering research spectrum, but their clinical translation has been limited. Herein, we comprehensively review the agents and products that have been developed to mitigate post-operative adhesion formation. We also assess emerging strategies that aid in facilitating precision and personalized medicine to improve outcomes for patients and our healthcare system.

Abstract
Intrauterine adhesion (IUA), and its severe form Asherman syndrome (Asherman’s syndrome), is a mysterious disease, often accompanied with severe clinical problems contributing to a significant impairment of reproductive function, such as menstrual disturbance (amenorrhea), infertility or recurrent pregnancy loss. Among these, its correlated infertility may be one of the most challenging problems. Although there are many etiologies for the development of IUA, uterine instrumentation is the main cause of IUA. Additionally, more complicated intrauterine surgeries can be performed by advanced technology, further increasing the risk of IUA. Strategies attempting to minimize the risk and reducing its severity are urgently needed. The current review will expand the level of our knowledge required to face the troublesome disease of IUA. It is separated into six sections, addressing the introduction of the normal cyclic endometrial repairing process and its abruption causing the formation of IUA; the etiology and prevalence of IUA; the diagnosis of IUA; the classification of IUA; the pathophysiology of IUA; and the primary prevention of IUA, including (1) delicate surgical techniques, such as the use of surgical instruments, energy systems, and pre-hysteroscopic management, (2) barrier methods, such as gels, intrauterine devices, intrauterine balloons, as well as membrane structures containing hyaluronate–carboxymethylcellulose or polyethylene oxide–sodium carboxymethylcellulose as anti-adhesive barrier.

Abstract
Background Adhesion due to intrauterine surgery such as septal resection associated with damaged endometrium can increase the risk of Asherman's syndrome. The main goal of treatment in this syndrome is to repair the damaged endometrium for creating a physiological pregnancy. Objective To investigate the effect of intrauterine injection of hyaluronic acid on the prevention of Asherman's syndrome in women undergoing uterine septum resection. Materials and Methods In this double-blind randomized clinical trial, 65 women undergoing the uterine septum resection were divided into two groups; the case group (n = 34) and the control group (n = 31). Immediately after the septal resection with a resectoscope, 1cc of hyaluronic acid gel in the case group and 1cc normal saline solution as a placebo in the control group was injected into the uterine cavity. After two months, existence of intrauterine adhesions in the both groups was examined by the hysteroscope and assessment of menstrual patterns, according to the American Society for Reproductive Medicine criteria. Results Our results showed that after intervention, the incidence of Asherman's syndrome in the control group was higher than the case group (p = 0.012). In the case group, only four women had poor adhesion (Asherman's syndrome) at the end of the study, while the rest of them were free of any adhesions in the uterine cavity. In the control group, however, only 19 were free of intrauterine adhesions and 12 had mild symptoms. Conclusion The results of the study exhibited the hyaluronic acid capacity to reduce the risk of Asherman's syndrome in women with endometrial damage following a septal resection surgery.

Abstract
PURPOSE To investigate the efficacy and safety of a newly developed thermo-responsive sol-gel, ABT13107, for reducing the formation of intrauterine adhesions (IUAs) after hysteroscopic surgery. MATERIALS AND METHODS In this multicenter, prospective, randomized trial (Canadian Task Force classification I), 192 women scheduled to undergo a hysteroscopic surgery at one of the eight university hospitals in South Korea were randomized into the ABT13107 group or the comparator (Hyalobarrier®) group in a 1:1 ratio. During hysteroscopic surgery, ABT13107 or Hyalobarrier® was injected to sufficiently cover the entire intrauterine cavity. RESULTS The patients returned to their respective sites for safety assessments at postoperative weeks 1 and 4 and for efficacy assessments at postoperative week 4. The post-surgery incidence of IUAs was 23.4% in the ABT13107 group and 25.8% in the comparator group; this difference met the criteria for ABT13107 to be considered as not inferior to the comparator. No differences were found in the extent of adhesions, types of adhesions, or the cumulative American Fertility Society score between the two treatment groups. Most adverse events were mild in severity, and no serious adverse events occurred. CONCLUSION ABT13107, a new anti-adhesive barrier containing hyaluronic acid, was not inferior to the highly viscous hyaluronic acid anti-adhesive barrier, Hyalurobarrier® in IUA formation after hysteroscopic surgery (Clinical trial registration No. NCT04007211).

Abstract
Asherman syndrome is a multifaceted condition describing the partial or complete removal of the uterine cavity and/or cervical canal. It is a highly debatable topic because of its pronounced influence on both reproductive outcomes and gynaecologic symptoms. The latest reports demonstrated that trauma to the endometrium is the main cause of intrauterine adhesion formation. Left untreated, such adhesions gradually lead to a range of repercussions ranging from mild to severe. Considering the lack of non-invasive approaches, the advent of hysteroscopy has revolutionized the entire field, being otherwise considered the most efficient tool offering new directions and amplifying the chances of treating the Asherman syndrome.

Crosslinked Hyaluronic Acid Gels for the Prevention of Intrauterine Adhesions after a Hysteroscopic Myomectomy in Women with Submucosal Myomas: A Prospective, Randomized, Controlled Trial. Life (Basel) 2020; 10:life10050067. [PMID: 32429137 PMCID: PMC7280993 DOI: 10.3390/life10050067] [Citation(s) in RCA: 17] [Impact Index Per Article: 4.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/20/2020] [Revised: 05/10/2020] [Accepted: 05/13/2020] [Indexed: 01/12/2023] Open
Abstract
Intrauterine adhesion (IUA), fibrosis, and scarring resulting from damage to the endometrium is a rare but serious clinical disease, contributing to a significant impairment of reproductive function. Uterine instrumentation, especially that of a hysteroscopic myomectomy, has become the main cause of IUA. Therefore, a prospective randomized controlled study to assess the effectiveness and short-term safety of the use of hyaluronic acid gels in the prevention of IUA after a hysteroscopic myomectomy and an evaluation of the characteristics of IUA observed at follow-up are presented here. A total of 70 patients were analyzed at the end of 16 March 2020. The results show that the incidence of IUA in women who underwent a hysteroscopic myomectomy is 21.4% (15/70), overall. Women treated with hyaluronic acid gels have a statistically significantly lower incidence of IUAs than non-treated women (12.8% vs. 39.1%, p = 0.012). In addition, women in the anti-adhesive gel treatment group had a dramatically reduced severity of IUA than women in the no-treatment group (p = 0.002). Further analysis shows that the International Federation of Gynecology and Obstetrics (FIGO) classification type and the use of anti-adhesive gels are independent factors associated with moderate and severe degrees of IUA formation. The results here highlight the significant therapeutic benefits of the application of hyaluronic acid gels in women undergoing a hysteroscopic myomectomy, especially for those patients with a uterine myoma classified as FIGO type 2. Since the risk of IUA after a hysteroscopic myomectomy is high, especially for patients who have not received prophylactic anti-adhesive gels, the application of hyaluronic acid gels as a prevention strategy is highly recommended. More studies are encouraged to confirm our observation.

Abstract
RESEARCH QUESTION Intrauterine adhesions (IUA) are primarily caused by trauma to the endometrium, and hysteroscopy is presently the main treatment for IUA. However, high rates of post-operative adhesion re-formation remain a problem. In this study, the combination of an intrauterine device (IUD) with a Foley catheter and the balloon uterine stent were investigated to evaluate their efficacy in preventing adhesion re-formation and the subsequent reproductive outcomes in patients with moderate to severe adhesions. DESIGN A prospective randomized controlled study was conducted in a university-affiliated hospital. A total of 171 women with Asherman's syndrome were initially recruited between August 2016 and December 2017 and were randomized to undergo either balloon uterine stent insertion or placement of a contraceptive IUD plus a Foley catheter after hysteroscopic adhesiolysis. Reduction of adhesion scores, incidence of adhesion re-formation, changes in menstrual flow and reproductive outcomes were analysed. RESULTS A total of 118 participants were eligible for analysis. The American Fertility Society (AFS) scores were not significantly different between groups before hysteroscopic adhesiolysis. At the second-look hysteroscopy, the AFS scores and adhesion recurrence rates were significantly higher in the balloon uterine stent group compared with the combination group (P < 0.01 and P = 0.024, respectively). There were no statistically significant differences in pregnancy and live birth rates between the two groups. CONCLUSIONS The combination of an IUD and a Foley balloon catheter had better efficacy in preventing adhesion re-formation than the balloon uterine stent alone; however, it did not produce better reproductive outcomes.

Abstract
Intrauterine adhesion is a severe complication after intrauterine operation, Various adjuvant therapies failed to improve clinical symptoms and pregnancy rates among patients with moderate-to-severe intrauterine adhesion. At present, hyaluronic acid gel is widely used in the primary prevention of adhesion after hysteroscopic adhesiolysis. However, its efficacy is still under debate. Therefore, the aim of this study was to systematically evaluate the efficacy of hyaluronic acid gel in preventing the recurrence of intrauterine adhesion after hysteroscopic adhesiolysis. The Cochrane Library, Embase, and PubMed databases were used to search for articles published before July 31, 2018, using the following terms: hyaluronic acid, intrauterine adhesions, Asherman's syndrome, IUA, hysteroscopy, and hysteroscopic adhesiolysis. Studies on therapies after hysteroscopic adhesiolysis were collected. The recurrence rate of and pregnancy rate in the presence of intrauterine adhesion after hysteroscopic adhesiolysis were analyzed by RevMan 5.3 software. A total of 6 articles were selected, which included 394 patients who were subjected to hysteroscopic adhesiolysis. The meta-analysis results showed that (1) no statistically significant difference was found between hyaluronic acid gel use and without its use on the score of intrauterine adhesion after hysteroscopic adhesiolysis [the mean difference (MD) = -0.89, 95% confidence interval (CI) (-2.53-0.76), P = 0.29], neither a statistically significant difference was observed between the same groups on the recurrence rate of intrauterine adhesion [odds ratio (OR) = 0.75, 95% CI (0.31-1.81), P = 0.53]; (2) subgroup analysis showed that hyaluronic acid gel could reduce the rate of intrauterine adhesion recurrence in randomized controlled trials [OR = -0.28, 95% CI (0.14-0.56), P = 0.0006]. However, the recurrence rate of intrauterine adhesion after the use of hyaluronic acid gel was not statistically significant in non-randomized controlled experiments [OR = 1.53, 95% CI (0.79-2.95), P = 0.21]; (3) hyaluronic acid gel did not result in a significant effect on pregnancy rate after intrauterine adhesion separation [OR = 2.02, 95% CI (0.53-7.66), P = 0.3]. In conclusion, hyaluronic acid gel could reduce the recurrence rate of intrauterine adhesion, but had no significant effect on the postoperative pregnancy rate.

Abstract
Objectives: The objective of this study is to evaluate the efficacy of autocross-linked hyaluronic acid (HA) compared with intrauterine device (IUD) for preventing intrauterine adhesions (IUAs) in infertile patients after hysteroscopic adhesiolysis. Materials and Methods: A randomized clinical trial (ChiCTR-IOR-16007746). Upon completion of adhesiolysis, 3 ml of HA gel was placed into the uterine cavity in Group A; 3 ml of HA gel and an IUD were placed in Group B; and only an IUD was placed in Group C. A second hysteroscopic examination was performed in all patients at approximately 1 month postoperatively for the evaluation of IUA. The primary outcome measure was the effective rate of IUA prevention based on the American Fertility Society (AFS) scoring system. Results: Eighty-nine women were randomly distributed into two groups for intention to treat with 30 patients in Group A, 24 patients in Group B, and 35 patients in Group C. Patients were scored and stratified into three degrees and were enrolled using the simple random sampling method. The three groups were well balanced. There were no significant differences in age, endometrial thickness, the previous number of pregnancy, and the distribution of adhesion categories across mild, moderate, and severe between the three groups. The effective rate of IUA prevention, the AFS score after therapy, and the percentage improvements of Chinese score and AFS score before and after surgery were statistically significant difference between Groups A and C. The clinical pregnancy rate in Group A was higher than those in Groups B and C, but the difference was not statistically significant. Conclusion: HA gel has an advantage over an IUD in reducing IUA recurrence and decreasing adhesions.

Abstract
Intrauterine adhesion (IUA) is a severe complication that occurs following abortion, and hyaluronic acid gel has been used to prevent IUA following intrauterine operation. The present study aimed to systematically evaluate the efficacy of hyaluronic acid gel in preventing IUA following intrauterine operation. In the current study, a literature search was performed using PubMed, Cochrane Library and EMbase databases for randomized controlled clinical trials that used hyaluronic acid gel as an adjuvant therapy following intrauterine operation. The terms 'hyaluronic acid', 'intrauterine adhesions', 'Asherman's syndrome', 'IUA', 'dilatation and curettage', 'abortion' and 'hysteroscopic' were used to search for articles published online before July 31, 2018. RevMan 5.3 software was used to analyze the indicators of uterine cavity adhesion formation and pregnancy rates following intrauterine operation. A total of seven randomized controlled clinical studies were included, consisting of 952 patients who underwent intrauterine operation. The meta-analysis indicated that the use of hyaluronic acid gel reduced the incidence of IUA [relative risk (RR)=0.42; 95% confidence interval (CI)=0.30-0.57; P<0.001] and the score for IUA after an intrauterine operation (mean difference=-1.29; 95%=-1.73 to -0.84; P<0.001). A subgroup analysis revealed that the preventive effect of hyaluronic acid gel on IUA was not affected by the type of intrauterine operation, namely abortion (RR=0.40; 95% CI=0.26-0.62; P<0.001) and hysteroscopy (RR=0.44; 95% CI=0.28-0.68; P<0.001). The preventive effect of hyaluronic acid gel on IUA was also not affected by primary disorders/diseases including the following: Abortion (RR=0.48; 95% CI=0.29-0.78; P=0.003); IUA (RR=0.38; 95% CI=0.21-0.67; P<0.001) and submucosal myoma of the uterus, endometrial polyps or mediastinum uterus (RR=0.40; 95% CI=0.18-0.90; P=0.03). Hyaluronic acid gel improved pregnancy rates after intrauterine operations (RR=1.94; 95% CI=1.46-2.60; P<0.001). In conclusion, hyaluronic acid gel was indicated to significantly reduce the incidence of IUA following intrauterine operation, regardless of the type of intrauterine operation or the presence of primary diseases. Treatment with hyaluronic acid gel was also revealed to increase pregnancy rates following intrauterine operation.

Abstract
Intrauterine adhesions (IUAs) are a result of trauma to the basalis layer of the endometrium and may lead to clinical sequelae such as miscarriage, infertility, and menstrual irregularities. Hysteroscopy is recognized as the gold standard in diagnosis and management, although the optimal treatment after surgical intervention remains unclear. This review aimed to provide an update on the treatment options available after hysteroscopic adhesiolysis and to facilitate clinical management of patients with IUAs. To avoid duplicating previous work, the review focused on studies that compared various adjunctive postoperative treatments in patients receiving hormone therapy. Of 548 studies, 15 papers fit our criteria that compared post-resection treatment options in women with IUAs. Meta-analysis of the use of Foley catheter or amnion graft as an adjunctive therapy after adhesiolysis failed to show a statistical difference (odds ratio 1.55; 95% confidence interval 0.60-3.99). Meta-analysis could not be done for the 13 remaining studies as a result of extensive heterogeneity, bias, or non-comparable end points. The lack of a universal classification system for IUAs and the use of variable outcomes to measure the success of adjunctive treatment pose challenges in generating standard treatment recommendations. This review calls for the development of a universal classification system and studies with consistent parameters and end points to allow for the generation of standard treatment guidelines. On the basis of the available evidence, recommendation of specific adjunctive treatments after hysteroscopic adhesiolysis is unjustified.

Abstract
BACKGROUND Intrauterine adhesions are a severe complication after miscarriage. Hyaluronic acid gel has been used to prevent intrauterine adhesions after miscarriage. OBJECTIVE To systematically evaluate the efficacy of adjuvant therapy with hyaluronic acid gel to prevent intrauterine adhesions after miscarriage. SEARCH STRATEGY The Cochrane Library, Embase and PubMed databases were searched for articles published before 31 July 2018 using the terms: ('hyaluronic acid gel' or 'gel') and ('dilatation and curettage' or 'D&C' or 'abortion' or 'miscarriage' or 'hysteroscopic') and ('intrauterine adhesions' or 'Asherman syndrome' or 'IUA' or 'endometrial injury' or 'intrauterine adhesion'). SELECTION CRITERIA Randomized controlled trials of hyaluronic acid gel therapy after miscarriage. DATA COLLECTION AND ANALYSIS Four studies were included in the meta-analysis (625 patients in total). Dichotomous outcomes were expressed as relative risk (RR) with 95 % confidence intervals (CI). Continuous variables were expressed as standardized mean differences (SMD). MAIN RESULTS Hyaluronic acid gel reduced the intrauterine adhesion scores after miscarriage (SMD -0.68, 95 % CI -1.08~-0.28; p = 0.0008) and the incidence of postoperative intrauterine adhesions after miscarriage (RR 0.44, 95 % CI 0.29~0.67; p = 0.0001). Subgroup analysis found that hyaluronic acid gel reduced the incidence of moderate and severe intrauterine adhesions after miscarriage (RR 0.18, 95 % CI: 0.07~0.47; p = 0.0004), but had no effect on the incidence of mild intrauterine adhesions (RR 0.77, 95 % CI 0.42~1.19; p = 0.19). Hyaluronic acid gel also improved the pregnancy rate after miscarriage (RR 1.94, 95 % CI 1.46~2.60; p < 0.00001). CONCLUSION Hyaluronic acid gel significantly reduced the incidence of moderate and severe intrauterine adhesions and significantly improved the pregnancy rate after miscarriage.

Abstract
Intrauterine adhesions with symptoms like hypomenorrhea or infertility are known under the term Asherman's syndrome. Although the syndrome has been widely investigated, evidence of both prevention of the syndrome and the ideal treatment are missing. Understanding the pathogenesis of intrauterine adherences is necessary for the prevention of the formation of intrauterine scarring. Intrauterine adhesions can develop from lesion of the basal layer of the endometrium caused by curettage of the newly pregnant uterus. The syndrome may also occur after hysteroscopic surgery, uterine artery embolization or uterine tuberculosis. For initial diagnosis the less invasive contrast sonohysterography or hysterosalpingography is useful. The final diagnosis is based on hysteroscopy. Magnetic resonance imaging is required in cases with totally obliterated uterine cavity. Intrauterine adherences are classified in accordance with different classification systems based on the hysteroscopic diagnosis of severity and localization of adherences. Classification is necessary for the planning of surgery, information on prognosis and scientific purposes. Surgery is performed in symptomatic patients with either infertility or with painful periods. Intrauterine adherences are divided with a hysteroscope using scissors or a power instrument working from the central part of the uterus to the periphery. Peroperative ultrasonography is useful in an outpatient setting for the prevention of complications. Hysteroscopy with fluoroscopy is a solution in difficult cases. Use of intrauterine devices like balloon catheters or intrauterine contraceptive devices seems to be the preferred methods for the prevention of re-occurrence of adhesions after treatment. Both primary prevention after hysteroscopic surgery or curettage and secondary prevention of new adhesions after adhesiolysis have been investigated. The aim of this review was to summarize the literature on diagnosis, classification, treatment and prevention, based on a literature search with a wide range of search terms.

Abstract
Background and Objectives: The authors sought to assess the effect of the use of a new crosslinked hyaluronan (NCH) gel on the prevention of intrauterine adhesions (IUAs) in women underwent curettage in the second trimester. Methods: Between June 2016 and September 2017, 60 patients who underwent curettage for retained placental tissue after medically induced or spontaneous pregnancy loss in the second trimester were enrolled in the study. The patients were randomly assigned to 1 of 2 groups: Group 1 patients received curettage plus NCH gel (intervention group), and group 2 patients received curettage alone (control group). The main outcomes were the rate and severity of IUA formation, which were assessed by follow-up hysteroscopy performed in the ensuing 2–6 months. Results: The hysteroscopic findings were available for 20 patients in group 1 and 28 patients in group 2. IUAs were observed in 6 patients in group 2, while no IUAs was observed in group 1 (P = .007). IUAs were staged as mild in 4 patients (14.28%) and moderate in 2 patients (7.14%) in group 2 according to the American Fertility Society classification of IUAs. Conclusions: Our study demonstrates that NCH gel appears to be able to reduce the formation of IUAs in women who undergo curettage in the second trimester, although larger controlled, randomized, multicenter studies are needed to confirm these results.

Abstract
STUDY OBJECTIVES To evaluate the efficacy of a new crosslinked hyaluronan (NCH) gel in reducing the formation of intrauterine adhesions (IUAs) after dilation and curettage (D&C). DESIGN Randomized controlled trial (Canadian Task Force classification I). SETTINGS Six hospitals for maternal and child healthcare in China. PATIENTS A total of 300 patients were randomized to undergo D&C for delayed miscarriage without previous history of D&C. Twenty-six patients (9%) were lost to follow-up and were excluded from the analysis. INTERVENTIONS Women were randomly assigned to D&C alone (control group; n = 150) or D&C plus NCH gel application (NCH gel group; n = 150) with 1:1 allocation. MEASUREMENTS AND MAIN RESULTS All patients were evaluated using the American Fertility Society classification of IUAs during follow-up diagnostic hysteroscopy, scheduled at 3 months after D&C procedure. The primary endpoint was the number of women with IUAs at 3 months, and the secondary endpoints were adhesion scores and severity of IUAs. Postoperative efficacy data were available for 274 women (137 in each group). Intrauterine adhesion formations were observed in 13 of the 137 women (9.5%) in the NCH gel group and in 33 of the 137 women (24.1%) in the control group (p = .0012; relative risk [RR], 0.3939; 95% confidence interval [CI], 0.2107-0.7153), a difference of 14.6% (95% CI, 5.92%-23.28%) between the 2 groups. The extent of intrauterine cavity involved, type of adhesion and menstrual pattern, and cumulative adhesion scores were significantly lower in the NCH gel group compared with the control group (p = .0007, .008, .0012, and .0006, respectively). The proportion of women with moderate to severe IUAs was significantly lower in the NCH gel group than that in the control group (1 of 137 [0.7%] vs 16 of 137 [11.7%]; p = .0002; RR, 0.0625; 95% CI, 0.0084-0.4648), a difference of 11.95% (95% CI, 5.39%-16.51%) between the 2 groups. CONCLUSIONS The current study demonstrates that IUAs are frequently formed after D&C for delayed miscarriage in women without a previous history of D&C procedures, and the application of NCH gel significantly reduces IUA formation.

Abstract
BACKGROUND Observational evidence suggests a potential benefit with several anti-adhesion therapies in women undergoing operative hysteroscopy (e.g. insertion of an intrauterine device or balloon, hormonal treatment, barrier gels or human amniotic membrane grafting) for decreasing intrauterine adhesions (IUAs). OBJECTIVES To assess the effectiveness of anti-adhesion therapies versus placebo, no treatment or any other anti-adhesion therapy, following operative hysteroscopy for treatment of female subfertility. SEARCH METHODS We searched the following databases from inception to June 2017: the Cochrane Gynaecology and Fertility Group Specialised Register; the Cochrane Central Register of Studies (CRSO); MEDLINE; Embase; CINAHL and other electronic sources of trials, including trial registers, sources of unpublished literature and reference lists. We handsearched the Journal of Minimally Invasive Gynecology, and we contacted experts in the field. We also searched reference lists of appropriate papers. SELECTION CRITERIA Randomised controlled trials (RCTs) of anti-adhesion therapies versus placebo, no treatment or any other anti-adhesion therapy following operative hysteroscopy in subfertile women. The primary outcome was live birth. Secondary outcomes were clinical pregnancy, miscarriage and IUAs present at second-look hysteroscopy, along with mean adhesion scores and severity of IUAs. DATA COLLECTION AND ANALYSIS Two review authors independently selected studies, assessed risk of bias, extracted data and evaluated quality of evidence using the GRADE method. MAIN RESULTS The overall quality of the evidence was low to very low. The main limitations were serious risk of bias related to blinding of participants and personnel, indirectness and imprecision. We identified 16 RCTs comparing a device versus no treatment (two studies; 90 women), hormonal treatment versus no treatment or placebo (two studies; 136 women), device combined with hormonal treatment versus no treatment (one study; 20 women), barrier gel versus no treatment (five studies; 464 women), device with graft versus device without graft (three studies; 190 women), one type of device versus another device (one study; 201 women), gel combined with hormonal treatment and antibiotics versus hormonal treatment with antibiotics (one study; 52 women) and device combined with gel versus device (one study; 120 women). The total number of participants was 1273, but data on 1133 women were available for analysis. Only two of 16 studies included 100% infertile women; in all other studies, the proportion was variable or unknown.No study reported live birth, but some (five studies) reported outcomes that were used as surrogate outcomes for live birth (term delivery or ongoing pregnancy). Anti-adhesion therapy versus placebo or no treatment following operative hysteroscopy.There was insufficient evidence to determine whether there was a difference between the use of a device or hormonal treatment compared to no treatment or placebo with respect to term delivery or ongoing pregnancy rates (odds ratio (OR) 0.94, 95% confidence interval (CI) 0.42 to 2.12; 107 women; 2 studies; I² = 0%; very-low-quality evidence).There were fewer IUAs at second-look hysteroscopy using a device with or without hormonal treatment or hormonal treatment or barrier gels compared with no treatment or placebo (OR 0.35, 95% CI 0.21 to 0.60; 560 women; 8 studies; I² = 0%; low-quality evidence). The number needed to treat for an additional beneficial outcome (NNTB) was 9 (95% CI 5 to 17). Comparisons of different anti-adhesion therapies following operative hysteroscopyIt was unclear whether there was a difference between the use of a device combined with graft versus device only for the outcome of ongoing pregnancy (OR 1.48, 95% CI 0.57 to 3.83; 180 women; 3 studies; I² = 0%; low-quality evidence). There were fewer IUAs at second-look hysteroscopy using a device with or without graft/gel or gel combined with hormonal treatment and antibiotics compared with using a device only or hormonal treatment combined with antibiotics, but the findings of this meta-analysis were affected by evidence quality (OR 0.55, 95% CI 0.36 to 0.83; 451 women; 5 studies; I² = 0%; low-quality evidence). AUTHORS' CONCLUSIONS Implications for clinical practiceThe quality of the evidence ranged from very low to low. The effectiveness of anti-adhesion treatment for improving key reproductive outcomes or for decreasing IUAs following operative hysteroscopy in subfertile women remains uncertain. Implications for researchMore research is needed to assess the comparative safety and (cost-)effectiveness of different anti-adhesion treatments compared to no treatment or other interventions for improving key reproductive outcomes in subfertile women.

Abstract
Aim To compare new remineralizing agents calcium sodium phosphosilicate paste and casein phosphopeptide-amorphous calcium phosphate (CPP-ACP) paste with that of fluoridated toothpaste in remineralization of early carious lesions using scanning electron microscopy and energy-dispersive X-ray (SEM-EDX) analysis. Materials and methods Sixty sound extracted premolars were collected and placed in demineralizing solution for 4 days to produce artificial carious lesions. All specimens were evaluated for any loss of mineral content using SEM-EDX analysis. Samples were randomly assigned to three groups: Group I: Fluoridated toothpaste (control), group II: CPP-ACP paste, and group III: Calcium sodium phosphosilicate paste. Specimens were then treated with above-mentioned remineralizing agents and again measured for mineral content using SEM-EDX analysis. Results Group III (calcium sodium phosphosilicate paste) showed highest significant difference followed in descending order by group II (CPP-ACP paste) and group I (fluoridated toothpaste). Conclusion Calcium sodium phosphosilicate paste showed maximum remineralizing potential compared with CPP-ACP and fluoridated toothpastes.

Abstract
Aim To evaluate the effectiveness of resin infiltration on artificial caries lesion by assessing the depth of resin penetration and the change in microhardness of lesion postinfiltration. Materials and methods Totally 45 human extracted premolars were used to create an artificial demineralized lesion in enamel using demineralizing solution. A total of 15 samples (group I) were infiltrated with resin. The depth of resin penetration was studied using scanning electron microscope (SEM). Other half (n = 30) of samples was equally divided into three subgroups and Vickers hardness number (VHN) values were obtained to measure the surface microhardness as group 11 a—before demineralization, 11 b—after demineralization, IIc—postresin infiltration. Results Mean depth of penetration in group I was 516.8 urn. There was statistically significant increase in VHN values of demineralized lesion postresin infiltration (independent Student’s t-test, p < 0.001). Conclusion Penetration depth of the resin infiltrant was deep enough to render beneficial effects, while significant increase in microhardness was observed postresin infiltration. Clinical significance Infiltrant used can be considered as a valid treatment option for noncavitated lesions. How to cite this article Prajapati D, Nayak R, Pai D, Upadhya N, Bhaskar VK, Kamath P.

Abstract
Aim Emotional intelligence (EI) is the ability to use emotions effectively and productively. It is becoming increasingly clear that these skills are one of the primary foundations for better performance of students in classrooms and in the society as well and EI provides the basis for competencies important "in almost every job." So we accessed the EI of teenagers as a guide of their academic score. Study design We analyzed the correlation of academic score to the EI of teenagers in regular schools and part-time unconventional coaching institute using the Bar-On Emotional Quotient questionnaire. Results and conclusion The results of our study showed that empathy and self-actualization were highly developed in students of regular conventional school than those attending part-time unconventional coaching institute. The academic score had a significantly positive correlation with empathy, whereas a significantly negative correlation with interpersonal relations. Empathy, interpersonal relation, and impulsive control were significantly higher in females than males. Therefore by inculcating and working toward development of EI in the young generation, we can hope to achieve a more positive environment. How to cite this article Sekhri P, Sandhu M, Sachdev V.

Abstract
Background Oral clefts are among the common congenital birth defects with a broad phenotypic gamut. Since the epidermal ridges of the fingers and palms as well as the facial structures like lip, alveolus, and palate are formed from the same embryonic tissues during the same embryonic period, the genetic and environmental factors responsible for causing cleft lip and palate might also affect dermatoglyphic patterns. Aim Thus, study was undertaken to compare the dermato-glyphic pattern of children with orofacial clefts and normal children and to determine the correlation of dermatoglyphics with orofacial clefts. Materials and methods Total study sample consisted of 120 children in the age group of 3 to 16 years being divided into study and control groups. Dermatoglyphic data obtained from both control and study groups were then subjected to statistical analysis. Results Statistically no significant difference was found in the dermatoglyphic pattern and atd angle for both the groups. Conclusion It was observed that dermatoglyphics in orofacial clefts may not be distinctive. Further, large-scale studies are recommended to confirm the same.

Abstract
Intrauterine adhesions (IUAs) can lead to partial or complete closure of the uterine cavity, which may result in symptoms including abnormal menstruation, infertility, and pelvic pain. A network meta-analysis was performed to assess the effect of adjuvant therapy on the prevention and treatment of IUAs. We searched electronic databases, including PubMed, Embase, and the Cochrane Library, up to May 5, 2017, without language restrictions. The primary outcomes in the present analysis were the rate of IUAs for prevention and the rate of IUA recurrence for treatment. The secondary outcomes included the IUA score and the rate of severity of IUAs. The treatments were then ranked by the surface under the cumulative ranking curve (SUCRA). We included 20 articles that involved a total of 1891 patients in our analysis. In the outcomes of prevention-related studies, an alginate hyaluronate-carboxymethylcellulose membrane (ACH) (n = 10, SUCRA score = 93.3%) was the adjuvant treatment that most effectively reduced IUA incidence. It was followed by intercoat (n = 10, SUCRA score = 74.7%) and misoprostol (n = 10, SUCRA score = 68.6%). In addition, auto-cross-linked hyaluronic acid (ACP) (n = 3, SUCRA score = 83.2%) and intercoat (n = 3, SUCRA score = 66.4%) each corresponded to a relatively high preventive effect against severe IUAs. In the treatment-related studies, ACP plus a balloon (n = 4, SUCRA score = 96.3%) and a freeze-dried amnion graft plus a balloon (n = 4, SUCRA score = 62.7%) most effectively reduced IUA recurrence and had a high probability of most effectively reducing IUA scores. Therefore, according to the prophylactic analysis, ACH and intercoat were most likely to prevent IUA development. In our analysis of agents used to prevent severe IUAs, we found that ACP and intercoat provided significant advantages and had high reliability. In our analysis of treatments, ACP plus a balloon and freeze-dried amniotic agents plus a balloon were most likely to reduce IUA recurrence and IUA scores after adhesiolysis.

Abstract
OBJECTIVE To examine whether intrauterine application of auto-crosslinked hyaluronic acid (ACP) gel, after dilatation and curettage (D&C), reduces the incidence of intrauterine adhesions (IUAs). DESIGN Multicenter; women and assessors blinded prospective randomized trial. SETTING University and university-affiliated teaching hospitals. PATIENT(S) A total of 152 women with a miscarriage of <14 weeks with at least one previous D&C for miscarriage or termination of pregnancy. INTERVENTION(S) Women were randomly assigned to either D&C plus ACP gel (intervention group) or D&C alone (control group). A follow-up diagnostic hysteroscopy was scheduled 8-12 weeks after the D&C procedure. MAIN OUTCOME MEASURE(S) The primary outcome was the number of women with IUAs and the secondary outcome was the severity of IUAs. RESULT(S) Outcomes were available for 149 women: 77 in the intervention group and 72 in the control group. The IUAs were observed in 10 (13.0%) and 22 women (30.6%), respectively (relative risk, 0.43; 95% confidence interval 0.22-0.83). Mean adhesion score and the amount of moderate-to-severe IUAs were significantly lower in the intervention group according to the American Fertility Society (AFS) and European Society of Gynecological Endoscopy classifications systems of adhesions. CONCLUSION(S) Intrauterine application of ACP gel after D&C for miscarriage in women with at least one previous D&C seems to reduce the incidence and severity of IUAs but does not eliminate the process of adhesion formation completely. Future studies are needed to confirm our findings and to evaluate the effect of ACP gel on fertility and reproductive outcomes. CLINICAL TRIAL REGISTRATION NUMBER NTR 3120.

Abstract
Objective Cavity preparation is a surgical procedure that attempts to remove all infected dentin.1 Bacteria left beneath the filling material is greatest threat to the pulp. To reduce the potential for residual caries development and sensitivity, an antibacterial solution with the ability to disinfect the prepared tooth surface would be of help.2 So this study was conducted to evaluate and compare the effect of dentin disinfection with 2% chlorhexidine gluconate (Consepsis) and 0.3% iodine (Ora5) on shear bond strength (SBS) of self-etch adhesives to dentin. Materials and methods Buccal surfaces of 36 caries-free permanent third molars were ground to expose dentin. All specimens were mounted on acrylic block, divided randomly into three groups, namely group I (control), group II (Con-sepsis), and group III (Ora5). After the application of cavity disinfectant and bonding procedures as per manufacturer’s instructions, composite cylinders were built. Then SBS was measured using universal testing machine. Results Statistical analysis of the measurements were made using one-way analysis of variance (ANOVA), which showed that when cavity disinfectants (Consepsis and Ora5) were used there was significant reduction in SBS of composite to dentin when compared with that of control group. Interpretation and conclusion The results indicate that the use of commercially available cavity disinfectants, Consepsis containing 2% chlorhexidine gluconate and Ora5 containing 0.3% iodine and 0.15% potassium iodide with self-etch adhesive (Adper Prompt), would significantly lower SBS of composite to dentin.

Abstract
Aims and objectives The purpose of this study is to determine the appropriate reference standard for eruption timing of primary teeth in infants and preschool children of Bhopal city and to determine the role of various factors affecting the eruption of primary dentition. Materials and methods A cross-sectional study was conducted among the infants and preschool children (4-36 months) attending the local government or private hospitals, and vaccination centers. Prior to the study, Institutional Ethical Committee clearance and informed written consent from the parents were obtained. The data were collected from full-term infants and preschool children of 4 to 36 months from Bhopal city. Oral examination was done under adequate natural light by a single examiner using mouth mirror and probe. Teeth present in the oral cavity were noted by using Federation Dentaire Internationale system of nomenclature in the preformed pro-forma. The teeth were considered as erupted, when any part of its crown had penetrated the gingiva and was visible in the oral cavity. Height, weight, birth weight, and other close-ended questions in questionnaire were asked from parents. Results and conclusion The data collected were statistically analyzed and it was observed that significant relation exists between tooth eruption and birth weight, feeding habits, socioeconomic status, and body mass index (BMI). Based on the findings, it may be concluded that Indian children experienced delayed eruption of primary teeth when compared with children of different countries and standard norms.

Abstract
Introduction Bacteria and their products play a primary etiological role in the initiation and perpetuation of pulpoperiapical pathosis. Intracanal medication is important for endodontic success as it eliminates microorganisms that persist after chemomechanical preparation. Aim To compare antimicrobial efficacy of calcium hydroxide powder, triple antibiotic paste, calcium hydroxide with 2% chlorhexidine solution, and triple antibiotic paste with 2% chlorhexidine solution. Materials and methods A total of 48 nonvital primary teeth were included in this study. After access opening first microbiological sample (s1) was collected by using absorbent paper point introducing into canal. Second microbilogical sample (s2) was taken following chemomechanical preparation and the teeth were divided into four groups: Group I: calcium hydroxide (CH) powder with distilled water; group II: CH with 2% chlorhexidine solution; group III: triple antibiotic powder with distilled water; group IV: triple antibiotic paste with 2% chlorhexidine solution. Then the canals were filled with any one group of the medicament and cavity was temporarily sealed with zinc oxide eugenol. After 1 week, a postmedication sample (s3) was collected. Then the canal was filled with Metapex, restored with glass ionomer cement. Conclusion From the experiments carried out in this study, with the limitations, an inference can be drawn that a combination of antimicrobial agent used as intracanal medicament is definitely better than single agent like Ca(OH)2.

Abstract
Introduction With greater awareness worldwide, the use of herbs and herbal products has increased to a large extent. Objective To evaluate and compare the antimicrobial efficacy of green tea, garlic with lime, and 0.05% sodium fluoride (NaF) mouth rinses against Streptococcus mutans, Lactobacilli species, and Candida albicans. Materials and methods A total of 45 children aged 4 to 6 years with severe early childhood caries (S-ECC; based on decayed extracted filled [defs] score) were selected. Children were divided randomly into three equal groups and were asked to rinse with the prescribed mouth rinse once daily for 2 weeks after breakfast under supervision. A base-line and postrinsing nonstimulated whole salivary sample (2 mL) was collected and tested for the number of colony-forming units (CFUs). The data were statistically analyzed using Statistical Package for the Social Sciences (SPSS) version 16.0 software with one-way analysis of variance (ANOVA) and Tukey’s post hoc test. Results A statistically significant fall in colony count was found with the three mouth rinses in S. mutans (p < 0.001, p < 0.001) and Lactobacilli spp. (p < 0.001, p < 0.001), but not against C. albicans (p = 0.264, p = 0.264). On comparison, no statistically significant difference was found against S. mutans (p = 1, p = 0.554, p = 0.572), lactobacilli spp. (p = 0.884, p = 0.999, p = 0.819), and C. albicans (p = 0.999, p = 0.958, p = 0.983). Conclusion The findings of this study indicate that green tea and garlic with lime mouth rinse can be an economical alternative to NaF mouth rinse both for prevention and therapeutics.

Abstract
Background The medicament formocresol (FC) used for pulpotomy in primary teeth has great concerns regarding its toxicity due to one of its constituent formaldehyde which acts by tissue fixation. Therefore, new medicaments were introduced which claimed preservation and regeneration of pulp. Aim The present study is aimed to compare and evaluate the clinical and radiographic success of FC, pulpotec, mineral trioxide aggregate (MTA), and emdogain (EMD) as pulpotomy medicaments in human primary molars. Design A sample of 21 patients with 84 teeth were selected. All the patients have at least four teeth eligible for pulpotomy according to selection criteria. In each mouth, the teeth selected were randomly allocated into four groups with 21 each. Results After 24 months of follow-up, the clinical success rates were FC (94%), pulpotec (94%), MTA (100%), and EMD (83%) and radiographically FC (88%), pulpotec (83%), MTA (94%), and EMD (72%), which were statistically not significant (p > 0.05). Conclusion The outcome of this study demonstrates MTA has a high success rate compared with FC, pulpotec, and EMD as pulpotomy agent. In addition, MTA, pulpotec, and EMD can be considered as alternatives to FC as pulpotomy agent. How to cite this article Sunitha B, Puppala R, Kethineni B, Mallela MK, Peddi R, Tarasingh P.

Abstract
Background Elevated fibrosis has been found in patients with intrauterine adhesion, which indicates that fibrotic factors may play a critical role in formation of intrauterine adhesion. The aim of this study was to identify the effect of hyaluronic acid (HA) at high and low molecular weight on fibrosis of the endometrium in a mouse model of Asherman’s syndrome. Material/Methods Endometrial fibrosis in a mouse model of Asherman’s syndrome was confirmed. Then HA at high and low molecular weight was injected into the uterine cavity. Endometrial fibrosis was compared among the control group, LMW-HA, and HMW-HA group. The extent of endometrial fibrosis was calculated using Masson stain. The fibrosis markers (TGFβ1, CTGF, collagen I, and collagen III) in endometrial tissue were detected using immunohistochemistry and Western blotting. Results The ratio of the area with endometrial fibrosis to total endometrial area in the HMW-HA group was significantly decreased compared to the control group (P<0.05). The expression of fibrosis markers (TGFβ1, CTGF, collagen I, and collagen III) in the endometrium was attenuated in the HMW-HA group compared to the control group, but the LMW-HA group had no similar effect. Conclusions Hyaluronic acid at high molecular weight may attenuate the degree of endometrial fibrosis after endometrial damage, which may contribute to preventing formation of intrauterine adhesions.

Intrauterine adhesion prevention after hysteroscopy: a systematic review and meta-analysis. Am J Obstet Gynecol 2016; 215:267-275.e7. [PMID: 27173082 DOI: 10.1016/j.ajog.2016.05.001] [Citation(s) in RCA: 92] [Impact Index Per Article: 11.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/22/2016] [Revised: 04/22/2016] [Accepted: 05/02/2016] [Indexed: 11/27/2022]
Abstract
BACKGROUND Despite years of studies evaluating prevention strategies for intrauterine adhesion formation after operative hysteroscopy, it is still unclear which strategies are most effective. OBJECTIVE The objective of the study was to perform a systematic review and meta-analysis to evaluate the effectiveness of postoperative prevention strategies on intrauterine adhesion formation following operative hysteroscopy. STUDY DESIGN Literature searches were conducted in MEDLINE, Embase, ClinicalTrials.gov, and Cochrane Library databases. Inclusion criteria were published randomized controlled clinical trials from 1989 to 2014 comparing any postoperative preventative measures of intrauterine adhesion after hysteroscopy. The main outcome measure was a reduction in postoperative intrauterine adhesion. Heterogeneity of the studies was evaluated using a Q test and an I(2) index. Analyses were performed using a random-effects model with outcome data reported as relative risk with 95% confidence interval. RESULTS Twelve studies were included in the systematic review. Eight studies compared similar treatment methods and were included in the meta-analysis. Three studies evaluated hyaluronic acid gel, of which 2 reported a significant decrease in intrauterine adhesion with treatment. The meta-analysis demonstrated a significant reduction of intrauterine adhesion when using hyaluronic acid gel. Two studies evaluated polyethylene oxide-sodium carboxymethylcellulose gel, 1 of which demonstrated a decrease in intrauterine adhesion with treatment. A meta-analysis showed a significant reduction of intrauterine adhesion with polyethylene oxide-sodium carboxymethyl cellulose gel. However, these 3 studies demonstrating a benefit of the gels in preventing adhesion formation were all conducted by the same research group. Other research groups have not confirmed these results. A sensitivity analysis excluding these trials from this single group demonstrated no benefit to adhesion prevention with either gel formation. Three studies investigated oral estrogen therapy after hysteroscopy and found no difference in intrauterine adhesion. A meta-analysis showed no decrease in intrauterine adhesion with estrogen therapy after hysteroscopy. Data were lacking to perform metaanalyses on the use of intrauterine balloon, intrauterine device, and other adhesion prevention barriers in preventing intrauterine adhesion. CONCLUSION There was a lack of definitive evidence to conclude that any treatment is effective in preventing posthysteroscopy uterine adhesion formation. The available literature has significant heterogeneity and a high risk of bias, making any definitive conclusions difficult.

Abstract
BACKGROUND Limited observational evidence suggests potential benefit for subfertile women undergoing operative hysteroscopy with several anti-adhesion therapies (e.g. insertion of an intrauterine device (IUD) or balloon, hormonal treatment, barrier gels or human amniotic membrane grafting) to decrease intrauterine adhesions (IUAs). OBJECTIVES To assess the effectiveness of anti-adhesion therapies versus placebo, no treatment or any other anti-adhesion therapy following operative hysteroscopy for treatment of female subfertility. SEARCH METHODS We searched the following databases from inception to March 2015: the Cochrane Menstrual Disorders and Subfertility Specialised Register, the Cochrane Central Register of Controlled Trials (2015, Issue 2), MEDLINE, EMBASE, the Cumulative Index to Nursing and Allied Health Literature (CINAHL) and other electronic sources of trials, including trial registers, sources of unpublished literature and reference lists. We handsearched The Journal of Minimally Invasive Gynecology, and we contacted experts in the field. SELECTION CRITERIA Randomised comparisons of anti-adhesion therapies versus placebo, no treatment or any other anti-adhesion therapy following operative hysteroscopy in subfertile women. The primary outcome was live birth or ongoing pregnancy. Secondary outcomes were clinical pregnancy, miscarriage and IUAs present at second look, along with their mean adhesion scores or severity. DATA COLLECTION AND ANALYSIS Two review authors independently selected studies, assessed risk of bias, extracted data and evaluated quality of the evidence using the GRADE (Grades of Recommendation, Assessment, Development and Evaluation) method. MAIN RESULTS We included 11 randomised studies on use of an inserted device versus no treatment (two studies; 84 women) or another inserted device (one study; 162 women), hormonal treatment versus no treatment or placebo (two studies; 131 women), gel versus no treatment (five studies; 383 women) and graft versus no graft (one study; 43 women). The total number of women randomly assigned was 924, but data on only 803 participants were available for analysis. The proportion of subfertile women varied from 0% (one study; 41 women), to less than 50% (six studies; 487 women), to 100% (one study; 43 women); the proportion was unknown in three studies (232 women). Most studies (9/11) were at high risk of bias with respect to one or more methodological criteria.We found no evidence of differences between anti-adhesion therapy and no treatment or placebo with respect to live birth rates (odds ratio (OR) 0.99, 95% confidence interval (CI) 0.46 to 2.13, P value = 0.98, three studies, 150 women; low-quality evidence) and no statistical heterogeneity (Chi(2) = 0.14, df = 2 (P value = 0.93), I(2) = 0%).Anti-adhesion therapy was associated with fewer IUAs at any second-look hysteroscopy when compared with no treatment or placebo (OR 0.36, 95% CI 0.20 to 0.64, P value = 0.0005, seven studies, 528 women; very low-quality evidence). We found no statistical heterogeneity (Chi(2) = 2.65, df = 5 (P value = 0.75), I(2) = 0%). The number needed to treat for an additional beneficial outcome (NNTB) was 9 (95% CI 6 to 20).No evidence suggested differences between an IUD and an intrauterine balloon with respect to IUAs at second-look hysteroscopy (OR 1.23, 95% CI 0.64 to 2.37, P value = 0.54, one study, 162 women; very low-quality evidence). AUTHORS' CONCLUSIONS Implications for clinical practiceThe quality of the evidence retrieved was low or very low for all outcomes. Clinical effectiveness of anti-adhesion treatment for improving key reproductive outcomes or for decreasing IUAs following operative hysteroscopy in subfertile women remains uncertain. Implications for researchAdditional studies are needed to assess the effectiveness of different anti-adhesion therapies for improving reproductive outcomes in subfertile women treated by operative hysteroscopy.
