Appendiceal mucoceles (AMs) are rare mucin-containing neoplasms with malignant potential. Lack of evidence-based data exists defining clinicopathological features for management. MEDLINE search between 1995 and 2015 was performed using search criteria “Appendix mucocele.” Systematic review of patient-, pathologic-, and treatment-related characteristics was performed and data analyzed. Among 276 cases of non-perforated AMs, 163 (59%) patients were female, with variable and nonspecific presentation. Patients were treated with appendectomy (52.1%), right hemicolectomy (17.6%), partial cecectomy (17.2%), and ileocecetomy (13.1%). Pathologic evaluation revealed the following: cystadenoma/low-grade appendiceal mucinous neoplasm (54%), unspecified/benign (25%), retention cyst (14.1%), cystadenocarcinoma (4.2%), and mucosal hyperplasia (2.9%). All 11 (4.2%) patients with cystadenocarcinoma were female ( P = 0.004), odds ratio for malignancy 1.07 times higher for women. Synchronous colonic malignancy was reported in three patients (27%) with cystadenocarcinoma ( P = 0.007), odds ratio of 12.1. AMs have low risk for malignancy. Treatment should begin with appendectomy-only and subsequently guided by pathologic diagnosis.

Abstract Background Optimum management of low-grade gliomas remains controversial, and widespread practice variation exists. This evidence-based meta-analysis evaluates the association of extent of resection, radiation, and chemotherapy with mortality and progression-free survival at 2, 5, and 10 years in patients with low-grade glioma. Methods A quantitative systematic review was performed. Inclusion criteria included controlled trials of newly diagnosed low-grade (World Health Organization Grades I and II) gliomas in adults. Eligible studies were identified, assigned a level of evidence for every endpoint considered, and analyzed according to Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines. The relative risk of mortality and of progression at 2, 5, and 10 years was calculated for patients undergoing resection (gross total, subtotal, or biopsy), radiation, or chemotherapy. Results Gross total resection was significantly associated with decreased mortality and likelihood of progression at all time points compared to subtotal resection. Early radiation was not associated with decreased mortality; however, progression-free survival was better at 5 years compared to patients receiving delayed or no radiation. Chemotherapy was associated with decreased mortality at 5 and 10 years in the high-quality literature. Progression-free survival was better at 5 and 10 years compared to patients who did not receive chemotherapy. In patients with isocitrate dehydrogenase 1 gene (IDH1) R132H mutations receiving chemotherapy, progression-free survival was better at 2 and 5 years than in patients with IDH1 wild-type gliomas. Conclusions Results from this review, the first to quantify differences in outcome associated with surgery, radiation, and chemotherapy in patients with low-grade gliomas, can be used to inform evidence-based management and future clinical trials.

BACKGROUND: Colorectal surgery is the highest incidence of adhesion-related problems. The type of surgery might be total coletomy, right hemicolectomy, left hemicolectomy, segmental colectomy, Hartmann procedure, and colostomy. Surgical procedures performed on the colon could be contaminated. The most common contamination is faecal contamination. Various causes of peritoneal irritation result in localized brin production, which results in adhesion to the surfaces in contact. PURPOSE: This study focused on the type of colorectal surgery and intra-abdominal contamination on the incidence of postoperative adhesions. METHOD: Systematic review and meta-analysis. We searched for published journal on types of colorectal surgery and contamination with adhesion events published from 2010-2020 using electronic database : Pubmed, Science Direct and Cochrane. RESULT: Ten journals (8 cohort and 2 case control) were included in the meta-analysis. In the risk factors for colorectal surgery: APR surgery, total colectomy and rectal resection had a signicant risk of postoperative adhesions with a pooled odds ratio of 1.74 (95% CI 1 respectively). ,10-2,78); 2.89 (95% CI 2.44-3.41) and 9.91 (95% CI 8.66-11.35). Intra-abdominal contamination also had a risk of adhesions with a pooled odds ratio of 863.47 (95% CI 177.73-4194.13). CONCLUSION: Types of colorectal surgery : APR, total colectomy, and rectal resection and intra-abdominal contamination had a risk of postoperative adhesions.

Abstract Objective: To review evidence-based data on spontaneous retrogression of low-grade gliomas with respect to interval till regression, type of glioma and patient outcome. Method: The systematic review comprised medical literature in English language published from January 1997 to January 2017 on Scopus, PubMed and Google Scholar databases to establish consensus about the possible mechanism of spontaneous regression, the role of therapeutic intervention and failure of management strategies in low-grade gliomas. Preferred Reporting Items for Systematic Reviews and Meta-Analysis guidelines were followed during the review. Results: Of the 176 articles identified, 73(41.5%) were shortlisted for detailed assessment. Of them, 10(13.7%) were included; 5(50%) case reports and 5(50%) case series. There were 23 cases of spontaneous regression; 15(65.2%) males and 8(34.7%) females. The interval of regression varied from 3 months to 15.5 years, and the most commonly presenting low-grade glioma type was optic pathway glioma 11(47.4%). Conclusion: The phenomenon of regression was most evident in optic pathway glioma. Literature suggested that low-grade gliomas should undergo serial imaging before implying any therapeutic intervention. However, the evidence-based proof, large-scale experimental studies and ethical considerations are still required to standardise this strategy.

Big international development donors such as the UK’s Department for International Development and USAID have recently started using systematic review as a methodology to assess the effectiveness of various development interventions to help them decide what is the ‘best’ intervention to spend money on. Such an approach to evidence-based decision-making has long been practiced in the health sector in the US, UK, and elsewhere but it is relatively new in the development field. In this article we use the case of a systematic review of the impact of microfinance on the poor in sub-Saharan African to indicate how systematic review as a methodology can be used to assess the impact of specific development interventions.
