ReviewSerum microRNA-195 as a potential diagnostic biomarker for breast cancer: a systematic review and meta-analysis.
Serum microRNA-195 (miR-195) expression has been shown to be significantly up-regulated in breast cancer, which implies that it could be a useful biomarker in the early detection of breast cancer. Hence, we performed this meta-analysis to investigate the diagnostic value of miR-195 for breast cancer. Relevant articles were collected from PubMed, Scopus, Embase, the Cochrane Library, BioMed Central, ISI Web of Knowledge, China National Knowledge Infrastructure, Wan Fang Data and Technology of Chongqing databases, from inception to May 24, 2019, by two independent researchers. ⋯ The pooled results for sensitivity, specificity and DOR were 0.79 (95% CI: 0.75-0.83), 0.86 (95% CI: 0.82-0.90) and 32.05 (95% CI: 17.04-60.30), respectively; positive and negative likelihood ratios were 5.18 and 0.20, and AUC was 0.9197 (95% CI: 0.86-0.91). In addition, heterogeneity was clearly apparent but was not caused by the threshold effect. In summary, this meta-analysis revealed that miR-195 may be suitable as a potential biomarker for early diagnosis of breast cancer with high sensitivity and specificity, and further investigations are needed to demonstrate its clinical application value.

Review Meta AnalysisEpsilon aminocaproic acid reduces blood transfusion and improves the coagulation test after pediatric open-heart surgery: a meta-analysis of 5 clinical trials.
Excessive postoperative blood loss after cardiopulmonary bypass is a common problem, especially in patients suffering from congenital heart diseases. The efficacy of epsilon aminocaproic acid (EACA) as a prophylactic treatment for postoperative bleeding after pediatric open-heart surgery has not been determined. This meta-analysis investigates the efficacy of EACA in the minimization of bleeding and blood transfusion and the maintenance of coagulation tests after pediatric open-heart surgery. ⋯ Prophylactic EACA minimizes postoperative blood transfusion and helps maintain coagulation in pediatric patients undergoing open-heart surgery. Therefore, the results of this study indicate that adjunctive EACA is a good choice for the prevention of postoperative blood transfusion following pediatric cardiac surgery.

Review Case ReportsBone formation following lenalidomide-dexamethasone combination therapy in cases of multiple myeloma refractory to high-dose chemotherapy with bortezomib and autologous peripheral blood stem cell transplantation: report of a case and review of the literature.
A 41-year-old man presented with the chief complaint of right hip pain that had persisted for 6 months. F18-fluorodeoxyglucose (FDG) positron emission tomography/computed tomography (PET/CT) imaging showed FDG accumulation in the right pubic bone. A bone biopsy specimen from the site revealed findings suggestive of a plasma cell tumor. ⋯ The patient was then administered eight cycles of combined lenalidomide-dexamethasone therapy, which resulted in a marked decrease of the FDG accumulation in the right pubic bone and disappearance of uptake in the right hip bone. There was radiographic evidence of bone formation at these sites. This is only the second reported case in which treatment with the immunomodulatory drug lenalidomide and concomitant dexamethasone has been found to induce bone formation.

Review Case ReportsMyxoid epithelioid gastrointestinal stromal tumor harboring an unreported PDGFRA mutation: report of a case and review of the literature.
Activating mutations of platelet-derived growth factor receptor α (PDGFRA) are detected in a significant proportion of gastrointestinal stromal tumors (GISTs), in addition to the more frequent mutation in c-kit. GISTs with PDGFRA mutations have been found to have several characteristic morphological features, sometimes allowing to discriminate them from GISTs with c-kit mutations. Among these, epithelioid morphology in tumor cells and tumor-infiltrating mast cells are powerful predictors of PDGFRA mutations. ⋯ The existence of a similar mechanism in eosinophil and mast cell recruitment via tumor-producing stem cell factor is speculated. Mutational analyses revealed a PDGFRA exon 18 mutation: D842_H845del, D846N. Combined deletion and substitution mutation has been reported in rare instances, but to the best of our knowledge, D846N has not been documented.

Review Case ReportsTenosynovial giant cell tumor arising from the posterior cruciate ligament: a case report and literature review.
The localized form of tenosynovial giant cell tumor or pigmented villonodular synovitis is rarely intraarticular in the knee. We reported a 40-year-old woman with a tenosynovial giant cell tumor arising from posterior cruciate ligament (PCL). She suffered sudden knee pain and locking without any reason for two days. ⋯ The histopathology of the mass demonstrated a tenosynovial giant cell tumor. At six weeks follow-up, no clinical evidence of recurrence was noted. A Literature Review of tenosynovial giant cell tumor or pigmented villonodular synovitis arising from the PCL is present.
