BACKGROUND Brain tumours represents 1.7 % of all cancers and contributes 1.8 % of all cancer deaths. Of all the brain tumours, 80 % are supratentorial.1 Magnetic resonance imaging (MRI) is an important modality, having higher sensitivity for detecting intracranial pathology. Multiplanar imaging is possible with MRI which helps in detection, localization and characterization of the lesion. MRI examination has helped in early diagnosis, accurate localization of the tumour, with prompt initiation of appropriate medical or surgical therapy. Recent advances like magnetic resonance (MR) spectroscopy, MR fluoroscopy with stereotactic guided biopsy have revolutionized the role of MRI in study of intracranial tumours. METHODS A cross sectional study of 75 patients was done by Siemens Essenza 1.5T MRI from June 2018 to June 2020 using dedicated head coil. RESULTS In our study, most of the patients were between 31 - 60 years of age (39 % of all patients) with the largest group between 31 - 40 years (20 % of all patients). Out of 75 cases of supratentorial neoplasms, 47 (72 %) were intra-axial lesions, 15 (23 %) were extra-axial lesions and 3 (5 %) were intra ventricular lesions. In this study, 69 % of the lesions were solitary and 31 % were multiple. Most of patients (89 %) showed some enhancement, most common being heterogeneous/inhomogeneous enhancement. Commonest type of supratentorial neoplasms were metastases comprising 29 % of this study. CONCLUSIONS Magnetic resonance imaging is an important modality, having higher sensitivity for detecting intracranial pathology. Multiplanar imaging is possible with MRI which helps in early detection, localization and characterization of the lesion. Metastasis is the most common supratentorial tumour in this study followed by meningioma. Intra-axial tumours are more common than extra-axial tumours in this study.

Final Sample

The objective was to characterize and compare the subgingival microbiota in patients diagnosed according to the World Workshop on the Classification of Periodontal and Peri-Implant Diseases and Conditions 2018. For this cross-sectional study, Spanish and Colombian subjects (characterized as health/gingivitis, periodontitis in stages I-II or stages III-IV) were clinically assessed, and subgingival samples were taken and processed by culture. The comparisons among patients with periodontal status (and between countries) was made using Mann–Whitney, Kruskal–Wallis, ANOVA and chi-square tests. The final sample consisted of 167 subjects. Eikenella corrodens and Parvimonas micra were more frequently detected in health/gingivitis and Porphyromonas gingivalis in periodontitis (p < 0.05). Higher total counts were observed in Colombia (p = 0.036). In Spain, significantly higher levels of P. gingivalis and Campylobacter rectus were observed, and of Tannerella forsythia, P. micra, Prevotella intermedia, Fusobacterium nucleatum, Actinomyces odontolyticus and Capnocytophaga spp. in Colombia (p < 0.001). P. micra was more prevalent in health/gingivitis and stage I-II periodontitis in Colombia, and P. gingivalis in all periodontitis groups in Spain (p < 0.05). As conclusions, significant differences were detected in the microbiota between health/gingivitis and periodontitis, with minor differences between stages of periodontitis. Differences were also relevant between countries, with Colombia showing larger counts and variability of bacterial species.
