Treatment strategies for erosive genital lichen planus: A systematic review of therapeutic modalities and emerging breakthroughs.

Background and Aims: Erosive genital lichen planus (EGLP) is a severe form of lichen planus characterized by painful erosions in the genital area, leading to significant distress and complications. This review aims to provide a thorough examination of EGLP, focusing on its clinical manifestations, diagnostic challenges, and various treatment strategies, with an emphasis on patient-centered care. Methods: Adhering to PRISMA guidelines, we conducted a systematic review of 26 studies that explored dermatological treatments for EGLP. Our literature search was comprehensive, covering PubMed, Scopus, and Web of Science. Data were extracted systematically using established tools to ensure a robust analysis of the treatment modalities. Results: EGLP presents with a range of symptoms, including severe pain, itching, and sexual dysfunction. Treatment options include topical corticosteroids, systemic medications, and surgical interventions. Despite the availability of various therapies, many cases are refractory to treatment, resulting in chronic symptoms and reduced quality of life. Emerging therapies show promise but are not yet established as standard practice. Conclusion: Management of EGLP requires a tailored, multidimensional approach. While topical corticosteroids remain essential, the development of new therapies offers hope for improved outcomes. A patient-centered approach is vital to address both the physical and psychosocial impacts of EGLP. Continued research is necessary to refine treatment protocols and enhance patient care.

Efficacy of preladenant in improving motor symptoms in Parkinson's disease: A systematic review and meta-analysis.

Background: Parkinson's disease (PD) is a complex neurodegenerative disorder characterized by dopamine depletion and severe motor impairments. Preladenant, an adenosine A2 receptor antagonist, is an investigational treatment for PD. This systematic review and meta-analysis aimed to critically evaluate the efficacy of Preladenant in improving motor symptoms in patients with PD. Methods: A comprehensive literature search was conducted in PubMed, Embase, and Cochrane Central Register of Controlled Trials from inception to March 2023, following the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines. Randomized controlled trials (RCTs) comparing Preladenant with placebo in PD patients were included. The primary outcome was the change in daily ON time without troublesome dyskinesia. Secondary outcomes included the change in daily OFF time and adverse events. The risk of bias was assessed using the Cochrane Risk of Bias tool. Results: Four RCTs with a total of 2097 PD patients were included. Pooled analysis showed that Preladenant could generally increase daily ON time (pooled effect 0.15 and 95 % CI: -0.19-0.48) and reduce daily OFF time (pooled effect -0.04 and 95 % CI: -0.43-0.36) compared to placebo, however it was not significant. The included studies had moderate to high heterogeneity. No significant differences in adverse events were observed between Preladenant and placebo. Conclusion: This meta-analysis suggests that Preladenant may improve motor fluctuations in PD patients by increasing ON time and reducing OFF time. However, the high heterogeneity among studies warrants further large-scale, high-quality RCTs to confirm these findings and establish the long-term safety and efficacy of Preladenant in PD management.

Assessing the Impact of Bariatric Surgery on Retinol-Binding Protein 4 (RBP4): A Systematic Review and Meta-Analysis.

This study aimed to analyze changes in retinol-binding protein 4 (RBP4) levels before and after bariatric surgery in obese individuals. Bariatric surgery is a safe and effective treatment for morbid obesity, impacting molecules like RBP4. A systematic review and meta-analysis of 12 relevant studies were conducted, utilizing databases such as PubMed, Cochrane Central, Web of Science, and Scopus. Significant differences in RBP4, glucose, and BMI levels pre- and post-surgery were observed. Meta-regression analysis explored associations with age, pre-BMI, triglycerides, glucose, and post-insulin levels. Findings suggest RBP4 may improve insulin sensitivity after bariatric surgery, warranting further investigation as a potential pharmacotherapeutic target. These results highlight the importance of understanding RBP4's role in the context of bariatric surgery and its implications for improving metabolic health in obese individuals.

The Effect of Bariatric Surgery on Irisin Level: a Systematic Review and Meta-analysis.

This systematic analysis and meta-analysis aimed to assess changes in the plasma levels of irisin after bariatric surgery. Search strategy, study screening, and data gathering were all conducted using a checklist and the guidelines of the Preferred Reporting Items for Systematic Reviews and Meta-Analysis (PRISMA). Two researchers independently extracted the data, and a third person was included to resolve disagreements. The results illustrated no statistical difference between before and after surgery irisin plasma levels (P = 0.216, 95% CI = -1.812-0.410, SMD = -0.701, I-squared = 94.9%). BMI exhibited a meaningful decline after surgery compared to preoperative values (SMD = -3.09, 95% CI = -4.59--1.59, I-squared = 95.5%, P<0.05). According to our analysis, it can be concluded that irisin plasma levels are not significantly influenced by bariatric surgery.

Clinical efficacy of endovascular treatment approach in patients with carotid cavernous fistula: A systematic review and meta-analysis.

Background and objectives: Carotid-cavernous fistulas (CCFs) represent a group of rare, abnormal arteriovenous communications between the carotid arterial system and the cavernous sinuses (CS). CCFs often produce ophthalmologic symptoms related to increased CS pressures and retrograde venous drainage of the eye. Although endovascular occlusion remains the preferred treatment for symptomatic or high-risk CCFs, most of the data for these lesions is limited to small, single-center series. As such, we performed a systematic review and meta-analysis evaluating endovascular occlusions of CCFs to determine any differences in clinical outcomes based on presentation, fistula type, and treatment paradigm. Method: A retrospective review of all studies discussing the endovascular treatment of CCFs published through March 2023 was conducted using PubMed, Scopus, Web of Science, and Embase databases. A total of 36 studies were included in the meta-analysis. Data from the selected articles were extracted and analyzed using Stata software version 14. Results: 1494 patients were included. 55.08% were female and the mean age of the cohort was 48.10 years. A total number of 1516 fistulas underwent endovascular treatment, 48.05% of which were direct and 51.95% of which were indirect. 87.17% of CCFs were secondary to a known trauma while 10.18% were spontaneous. The most common presenting symptoms were 89% exophthalmos (95% CI: 78.0-100.0; I2 = 75.7%), 84% chemosis (95% CI: 79.0-88.0; I2 = 91.6%), 79% proptosis (95% CI: 72.0-86.0; I2 = 91.8%), 75.0% bruits (95% CI: 67.0-82.0; I2 = 90.7%), 56% diplopia (95% CI: 42.0-71.0; I2 = 92.3%), 49% cranial nerve palsy (95% CI: 32.0-66.0; I2 = 95.1%), 39% visual decline (95% CI: 32.0-45.0; I2 = 71.4%), 32% tinnitus (95% CI: 6.0-58.0; I2 = 96.7%), 29% elevated intraocular pain (95% CI: 22.0-36.0; I2 = 0.0%), 31% orbital or pre-orbital pain (95% CI: 14.0-48.0; I2 = 89.9%) and 24% headache (95% CI: 13.0-34.0; I2 = 74.98%). Coils, balloons, and stents were the three most used embolization methods respectively. Immediate complete occlusion of the fistula was seen in 68% of cases and complete remission was seen in 82%. Recurrence of CCF occurred in only 35% of the patients. Cranial nerve paralysis after treatment was observed in 7% of the cases. Conclusions: Exophthalmos, Chemosis, proptosis, bruits, cranial nerve palsy, diplopia, orbital and periorbital pain, tinnitus, elevated intraocular pressure, visual decline and headache are the most common clinical manifestations of CCFs. The majority of endovascular treatments involved coiling, balloons and onyx and a high percentage of CCF patients experienced complete remission with the improvement of their clinical symptoms.

Systematic Review and Meta-analysis of the Relationship Between Proton Pump Inhibitors and Esophageal Adenocarcinoma.

INTRODUCTION AND AIM: Esophageal adenocarcinoma (EAC) mortality continues to increase across the world. This meta-analysis was aimed to investigate the relationship between proton pump inhibitors (PPIs) and the risk of EAC. METHODS: This meta-analysis was done as per the PRISMA checklist using relevant keywords. To this end, an extensive search was done on 29/6/2022 in EMBASE, Web of Science (ISI), PubMed, and Scopus. In this study, 95% confidence interval (CI) and standardized mean difference (SMD) were used to estimate the overall effect size. Analysis of the odds ratio (OR) for EAC was done using a random effects model. RESULTS: A total of 20 studies were included in the review. Compared to the group that received PPIs, the OR of EAC in the recipients of the PPIs group was obtained at 0.67 (95% CI = 0.39-1.29, P = 0.240). The meta-regression, including year, follow-up time, study design, sample size, quality of the study, study period, and geographical location, demonstrated no source of heterogeneity (P > 0.10). CONCLUSION: No significant relationship was found between PPIs use and the risk of EAC. Accordingly, PPIs do not have a protective or risk factor effect on EAC.

Diagnostic Performance of Magnetic Resonance Imaging for Detection of Acute Appendicitis in Pregnant Women; a Systematic Review and Meta-Analysis.

Introduction: The diagnosis of acute appendicitis (AA) in pregnant women is commonly challenging owing to the normal results of laboratory tests, organ displacement, and normal physiological inflammatory alterations. This meta-analysis aimed to investigate the accuracy of magnetic resonance imaging (MRI) in diagnosis of AA in pregnant women. Methods: Two investigators independently performed a comprehensive systematic literature search of electronic databases including MEDLINE, Cochrane Central, EMBASE, Web of Science, Scopus, and Google Scholar to identify studies that reported accuracy of MRI for diagnosis of AA in pregnant women from inception to April 1, 2022. Results: Our systematic search identified a total of 525 published papers. Finally, a total of 26 papers were included in the meta-analysis. The pooled sensitivity and specificity of MRI in diagnosis of AA in pregnant women were 0.92 (95% CI: 0.88-0.95) and 0.98 (95% CI 0.97-0.98), respectively. The pooled positive likelihood ratio and negative likelihood ratio were 29.52 (95% CI: 21.90-39.81) and 0.10 (95% CI: 0.04-0.25), respectively. The area under hierarchical summary receiver operating characteristic (HSROC) curve indicated that the accuracy of MRI for diagnosis of AA in pregnant women is 99%. Conclusion: This meta-analysis showed that MRI has high sensitivity, specificity, and accuracy for diagnosis of AA in pregnant women and can be used as a first-line imaging modality for suspected cases of AA during pregnancy. Furthermore, it should be noted that when the result of ultrasonography is inconclusive, the use of MRI can reduce unnecessary appendectomy in pregnant patients.
