Abstract Aims Biliary cooling during radiofrequency ablation (RFA) of liver tumours has been proposed as a protective measure for RFA-related biliary complications in cases whereby the RFA-site is close to central biliary tree. This systematic review aims to assess the effect of biliary cooling on i) the development of biliary complications and ii) tumour recurrence rates at ablation site. Methods A systematic literature search was performed using the PubMed/EMBASE databases using PRISMA methodology (2000-2019). The initial search yielded 75 reports which were potentially suitable for inclusion. Studies reporting at least one outcome of interest were considered to be suitable for inclusion. Conference abstracts, case reports and animal studies were excluded. Data was retrieved on patient demographics, tumour characteristics, method of cooling, biliary complications, local tumour recurrence and duration of follow-up. Results The final number of studies which met the inclusion criteria was 7, involving 100 patients. There were no randomized controlled trials identified after the literature search. The mean age of the patients included was 65 years. Biliary cooling was performed with the use of a nasobiliary tube in 4 out of 7 studies, via a choledochal incision in 2 out of 7 studies and through the cystic duct in a single study. The overall biliary stricture rate was 2% and the overall tumour recurrence rate at RFA treated site was 14.5%. Conclusion Biliary complications appear to be low after biliary cooling during RFA close to central biliary tree. More evidence is required to assess the tumour recurrence rates.

Abstract Background Barrett’s esophagus (BE) is a premalignant condition characterized by replacement of the esophageal lining with metastatic columnar epithelium, and its management when complicated by low grade dysplasia (LGD) is controversial. This systematic review and meta-analysis aimed to determine the efficacy of radiofrequency ablation (RFA) in patients with LGD. Methods MEDLINE, EMBASE, and Web of Science were searched for studies including patients with BE-associated LGD receiving RFA (January 1990 to May 2017). The outcome measures were complete eradication of intestinal metaplasia (CE-IM) and dysplasia (CE-D), rates of progression to high grade dysplasia (HGD) or cancer, and recurrence. Results Eight studies including 619 patients with LGD (RFA = 404, surveillance = 215) were analyzed. After a median follow-up of 26 months (range 12 – 44 months), the overall pooled rates of CE-IM and CE-D after RFA were 88.17 % (95 % confidence interval [CI] 88.13 % – 88.20 %; P < 0.001) and 96.69 % (95 %CI 96.67 % – 96.71 %; P < 0.001), respectively. When compared with surveillance, RFA resulted in significantly lower rates of progression to HGD or cancer (odds ratio [OR] 0.07, 95 %CI 0.02 – 0.22). The pooled recurrence rates of IM and dysplasia were 5.6 % (95 %CI 5.57 – 5.63; P < 0.001) and 9.66 % (95 %CI 9.61 – 9.71; P < 0.001), respectively. Conclusions RFA safely eradicates IM and dysplasia and reduces the rates of progression from LGD to HGD or cancer in the short term.

Meta Analyses

The number of people with cancer and the need for palliative care among this population is increasing in the United States. Despite this growing need, several barriers exist to the utilization of palliative care in oncology. The purpose of this study was to synthesize the evidence on the barriers to palliative care utilization in an oncology population. A systematic review of literature was conducted following the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines. PubMed, CINAHL, and Psych Info databases were used for the literature search. Articles were included if they: 1) focused on cancer, (2) examined and discussed barriers to palliative care, and c) were peer reviewed, published in English, and had an accessible full text. A total of 29 studies (8 quantitative, 18 qualitative, and 3 mixed-methods) were identified and synthesized for this review. The sample size of the included studies ranged from 10 participants to 313 participants. The barriers to palliative care were categorized into barriers related to the patient and family, b) barriers related to providers, and c) barriers related to the healthcare system or policy. The factors identified in this review provide guidance for intervention development to mitigate the existing barriers and facilitate the use palliative care in individuals with cancer.

Abstract Background Wrist arthrolysis is a viable option in wrist stiffness and can be performed via open or arthroscopic techniques. Purpose The aim of the study is to describe and evaluate the available techniques of open and arthroscopic arthrolysis of the radiocarpal joint and the distal radio ulnar joint (DRUJ) in posttraumatic wrist stiffness. Methods A systematic literature search was performed in PubMed to identify studies reporting on open and arthroscopic wrist arthrolysis. Key words included “open wrist arthrolysis,” “arthroscopic wrist arthrolysis,” “post-traumatic wrist stiffness,” and “DRUJ arthrolysis.” Data were extracted independently by a pair of reviewers. Results Overall, 637 studies were identified; 13 additional articles were found through previous publications (total 650 articles). A total of 612 records resulted after duplicates was removed. Fourteen studies were selected and only eight respected the inclusions criteria. One study focused on volar open arthrolysis and four studies on arthroscopic arthrolysis of the radiocarpal joint; two studies reported on open arthrolysis and two studies on arthroscopic DRUJ arthrolysis. Range of motion following open and arthroscopic wrist arthrolysis improved in all studies. Conclusion Both arthroscopic and open arthrolysis can lead to similar and satisfactory results in radiocarpal joint and DRUJ stiffness.. Level of Evidence This is a level 3a study.

Abstract Background Pressure ulcers (PUs) affect 2.5 million people in the United States annually and incur health-care costs of 11 billion dollars annually. Stage III/IV PU often require local flap reconstruction. Unfortunately, PU recurrence is common following reconstruction; recurrence rates as high as 82% have been reported. When local flap options are inadequate, free tissue transfer may be indicated but the indications have yet to be delineated. To develop evidence-based guidelines for the use of free flaps in PU reconstruction, we performed a systematic review. Methods A systematic review of the available English-language, peer-reviewed literature was conducted using PubMed/MEDLINE, Google Scholar, Scopus, EMBASE, and the Cochrane Database of Systematic Reviews. Articles were manually reviewed for relevance. Results Out of 272 articles identified, 10 articles were included in the final analysis. Overall, this systematic review suggests that free-flap PU reconstruction yields fewer recurrences compared with local flaps (0–20 vs. 13–82%). Further, several types of free flaps for PU reconstruction were identified in this review, along with their indications. Conclusion Free tissue transfer should be considered for recurrent PU. We offer specific recommendations for their use in PU reconstruction.

Neural Crest Origin

Melanotic Neuroectodermal Tumor of Infancy (MNTI) is a very rare pediatric neoplasm of neural crest origin. In most cases, it develops in infants as a localized tumor of the maxilla, and surgery is usually curative. In less than 10% of patients with inoperable, metastatic or persistently recurring MNTI, chemotherapy (CHT) may be considered; however, its role is still unclear. The aim of our study was to assess the efficacy of CHT in children with large, inoperable, metastatic and/or recurrent MNTI. Four such infants, treated with CHT in Polish and German centers of pediatric oncology, were presented. Additionally, a systematic literature search of the PubMed/MEDLINE, Scopus and Web of Science databases was performed, yielding 38 similar cases within the last 42 years. Neoadjuvant CHT, based mainly on the protocols for neuroblastoma, was often effective, allowing for complete delayed surgery in most cases. However, the role of adjuvant CHT in preventing recurrences after incomplete resection of MNTI remains unclear. Disseminated inoperable MNTI was almost universally associated with poor response to CHT and unfavorable outcome. Further investigations to elaborate standards of management in patients with inoperable, metastatic or persistently recurring MNTIs are necessary to improve outcomes.
