Introduction: Pseudo journals, hijacked journals, fraudulent journals, fake journals, and predatory journals waste valuable research when authors publish their studies in them. Aim: This article described novel suggested features for the identification of fraudulent journals and aimed to explain this issue to help inexperienced scientists avoid publishing in predatory journals. Methods: The articles related to this topic in were retrieved from PubMed and trustable Internet sources. Results: Unfortunately, some fake journals have made their way into reputable databases, such as PubMed, PubMed Central, MEDLINE, SCOPUS, and Web of Science; thus, the serious question has been raised regarding how we should address this problematic phenomenon. We recommended 28 suggested characteristics of predatory journals for readers to take into consideration. Conclusion: Unaware of the detrimental effects associated with publishing in disreputable journals, inexperienced researchers can fall victim to them. Together, as both readers and writers, we should completely boycott predatory journals.

Anaplastic astrocytoma, a diffusely infiltrating, malignant, astrocytic, primary brain tumor, is most commonly observed between 30 and 50 years of age. Anaplastic astrocytomas are now classified as WHO grade III lesions, with imaging characteristics and prognosis between diffuse low-grade astrocytomas (WHO grade II) and glioblastomas (WHO IV). Anaplastic astrocytoma can appear mostly in the cerebrum followed by cerebellum. However, it is rarely observed in the fourth ventricle. In this article, we aimed to describe an uncommon case of a pediatric, fourth-ventricular, anaplastic astrocytoma. A 9-year-old male who underwent MRI brain then adopted gross-total tumor eradication. The final histopathology findings were consistent with an anaplastic astrocytoma.

Purpose: To assess the values of computed tomography in T staging of gingival cancer. Methods: A retrospective cross-sectional study conducted with 102 patients who had CT-scans and pathology results of carcinoma of gingiva at Ho Chi Minh City Oncology Hospital. This study evaluated the diagnostic value of CT in assessing the stage and bone invasion of gingival cancer by comparing CT assessment and pathology assessment. Results: There were 102 cases of gingival cancer in the study sample, of which 46 cases had tumor surgically removed. CT measurements of tumor size showed a strong correlation with macroscopic measurements with a Spearman correlation coefficient of 0.77. CT showed high diagnostic value in assessing bone and retromolar trigone invasion with sensitivity of 97.6% and 88.8%, specificity of 71.4% and 91.7%, positive predictive value of 95.2% and 80.0%, negative predictive value of 83.3% and 95.7%, respectively. In comparison between CTscans and histologic analysis in T staging, showed good agreement, with weighted kappa index of 0.6 (95% CI, 0.4-0.9). Conclusion: Computed tomography is a valuable method in T staging of gingival cancer. The CT assessment should evaluate factors according to 8 th AJCC to accurately evaluate the disease stage.
