RESUMO
Objective: Endometrial carcinoma (EC) is the most common gynecologic malignancy in the USA and Western Europe. Surgery is the mainstay of both staging and treatment of EC. Fertility sparing medical therapies are often offered to young women who desire fertility. Metformin has been suggested to be an anti-cancer agent as evidenced by previous studies. It decreases Antigen Ki-67 (Ki-67) proliferation and expression which is associated with proliferative activity of malignant tumors. In this systematic review and meta-analysis, we assessed the efficacy of metformin on patients with EC. Materials and Methods: We searched PubMed, Cochrane CENTRAL, Web of Science, and SCOPUS for relevant clinical trials and excluded observational studies. The quality appraisal was evaluated according to GRADE, and we assessed the risk of bias using Cochrane's risk of bias tool. We conducted the analysis of continuous data using mean difference (MD). We included the following outcomes: Ki-67 index, glucose, insulin, P-S6, body mass index (BMI), C-peptide, Insulin-like growth factor (IGF-1), leptin, and hemoglobin. Results: Nine studies were eligible for our meta-analysis. We found that compared to the control group, metformin is highly effective in reducing Ki-67 proliferation and expression [MD=-10.14 (-19.10, -1.17)], (p=0.03), P-S6 [MD=-1.82 (-3.17, -0.46)], (p=0.009), plasma glucose level [MD=-1.76 (-4.88, 1.37), p=0.27], and BMI [MD=-1.07 (-1.49, -0.65)], (p<0.001). Conclusion: We conclude that metformin administration is effective in patients with EC. It decreases Ki-67 proliferation and expression, serum glucose, and p-S6 significantly.
RESUMO
We conducted a systematic review and meta-analysis of relevant clinical trials from full-text, scientific journal archives to assess the efficacy of hyoscine for the management of pain during in-office hysteroscopy (OH) procedures. Cochrane CENTRAL, ClinicalTrials.Gov, MEDLINE, PubMed, SCOPUS and the Web of Science were searched for all clinical trials that matched our search criteria. A full assessment of bias was made using the Cochrane Group tool-set. The following outcomes were included: visual analogue scale (VAS) score for postoperative pain, postoperative need for analgesia, and procedure time. In the case of homogeneous data, the analysis was performed using a fixed effects system, and the random effects system was used with heterogeneous data. Inclusion criteria included only randomized clinical trials, and interventions that included patients receiving hyoscine-N-Butyl Bromide during OH, regardless of dose or mode of administration, and compared this with placebo. Three clinical trials were included. The actual mean difference (MD) of the VAS pain score showed no significant difference between hyoscine or placebo [MD: -0.28 (-1.08, 0.52), (p=0.49)]. For postoperative analgesia, the overall MD showed no significant difference between hyoscine or placebo [MD: 0.43 (0.16, 1.14), (p=0.09)]. For procedure time, the combined effect estimate failed to show any significant difference between hyoscine and placebo [MD: -0.66 (-2.77, 1.44) (p=0.54)]. Contrary to previously published data, our meta-analysis using the latest available RCTs fails to show hyoscine as being effective in reducing pain or the need for other forms of anesthesia in OH.
RESUMO
Office hysteroscopy (OH) is a common procedure in gynecology. Pain is the most frequently reported problem in OH. In this study, we aimed to investigate the role of tramadol administration in relieving pain in women undergoing OH. We searched PubMed, the Cochrane Library, ClinicalTrials.gov, MEDLINE, Scopus, and Web of Science databases for relevant clinical trials based on our search terms. We included randomized controlled trials and included all published trials in all six searched databases from their inception until February 28th 2021. We included pain as the primary outcome, and the incidence of adverse events of tramadol as secondary outcomes. We performed the analysis of continuous data using mean difference (MD) and dichotomous data using risk ratio (RR). We found that tramadol led to significantly less pain during the actual procedure [MD=-1.27, 95% confidence interval (CI): (-1.66, -0.88); p<0.001], immediately after the procedure [MD=-1.03, 95% CI: (-1.40, -0.67); p<0.001], and 30 minutes after the procedure [MD=-0.74, 95% CI: (-1.06, -0.41); p<0.001]. Regarding safety endpoints, no significant difference was noted for dizziness [RR=1.88, 95% CI: (0.79, 4.47); p=0.16] or vomiting [RR=1.80, 95% CI: (0.40, 8.18); p=0.45]. Based on the available data, we conclude that tramadol administration seems to be both effective and safe for patients undergoing office hysteroscopy.
RESUMO
OBJECTIVE: We aimed to perform a systematic review and meta-analysis in order to evaluate the effect of paracervical anesthetic block among women undergoing laparoscopic hysterectomy. METHODS: A systematic search was done in Cochrane Library, PubMed, ISI web of science, and Scopus during January 2021. We selected randomized clinical trials (RCTs) compared paracervical anesthetic block versus normal saline (control group) among women undergoing laparoscopic hysterectomy. We pooled the continuous data as mean difference (MD) and dichotomous data as risk ratio (RR) with the corresponding 95% confidence intervals using Revman software. Our primary outcome was pain scores evaluated by visual analog scale (VAS) at 30 min and 1 hour. Our secondary outcomes were postoperative additional opioids requirement and length of hospital stay. RESULTS: Three RCTs met our inclusion criteria with a total number of 233 patients. We found that paracervical anesthetic block was linked to a significant reduction in VAS pain score at 30 min and 1 hour post-hysterectomy (MD= -2.13, 95% CI [-3.09, -1.16], p>0.001 & MD= -1.87, 95% CI [-3.22, -0.52], p = 0.006). There was a significant decrease in additional opioids requirement postoperatively among paracervical anesthetic block group in comparison with control group (p = 0.002). No significant difference was found between both groups regarding the length of hospital stay. CONCLUSION: Paracervical anesthetic block is effective in reducing postoperative pain after laparoscopic hysterectomy with decrease in opioids administration postoperatively.
