Introduction: Gadolinium deposition in the human brain, especially in the Globus Pallidus (GP) and the Dentate Nucleus (DN) has been reported after the administration of linear Gadolinium-Based Contrast Agents (GBCAs). This study aims to determine whether repeated injections of macrocyclic GBCA are associated with an increased Signal Intensity (SI) on T1-weighted sequences in the Globus Pallidus (GP) and Dentate Nucleus (DN) in oncologic pediatric patients. Materials and methods: This retrospective monocentric cohort study included consecutive children with at least two MRIs performed after administration of macrocyclic GBCAs. The SI measurements were determined on unenhanced T1-weighted images by drawing a circular region of interest (ROI) within GP and Thalamus (TH) and DN, Pons (P), at baseline, and at last MRI. SI ratios and the differences in ratios (GP/TH) and (DN/P) between the first and last MRI calculated. Results: Out of 413 consecutive children attending Leon Berard cancer center, 50 patients were included, and data analysis showed significantly increased GP/TH SI ratios between the first and the last MRI (p =0.0305). The DN/P SI ratios did not significantly differ between the first and the last MRI (p=0.2668). Conclusion: This study showed an increased SI in GP after several intravenous administrations of macrocyclic GBCAs but no increased SI was identified in the DN. Although no clinical adverse effects have been reported so far, the gadolinium deposits in the brain should be carefully monitored, especially in children who still undergo neurodevelopment.

The diagnostic criteria for the behavioral variant of frontotemporal dementia were revised recently. Distinguishing both disorders apart as brain imaging studies in patients with schizophrenia also demonstrate changes in the frontal and temporal lobes which can help in the diagnostic process. This paper highlights the challenges in diagnosing Treatment-Resistant Schizophrenia (TRS) with a differential diagnosis of Fronto-Temporal Dementia (FTD) from magnetic resonance imaging (MRI) imaging. From the diagnosis of the case study, it can be summarized that frontotemporal atrophy is often associated with FTD but it may also occur in a patient suffering from schizophrenia. This provides a challenge for medical practitioners to distinguish between FTD and schizophrenia as disinhibition and executive dysfunction may prominent in schizophrenia with (Frontotemporal Atrophy) FTA.

The purpose of this brief report is to stimulate further interest and to raise awareness in relation to the usefulness of assessing cardiac autonomic nerve function using heart rate variability (HRV). The paper outlines the mechanisms associated with HRV and the relationships between HRV, health, and athletic performance. The paper then summarizes the potential benefits of HRV in the assessment of health and exercise adaptations. The paper also provides suggestions about the practical implications of HRV measurement during data collection. We hope that the content provides useful information for the application of HRV for health evaluation and training adaptations. In addition, we hope the paper will provide a better understanding of how HRV measurements can be interpreted and used. Finally, the paper provides practical applications that are effective in the assessment of health and athletic training program outcomes.

Cemento-ossifying fibroma is a rare benign fibro-osseous neoplasm commonly involving the jaws majority of lesions occur in mandible bone. It can be discovered as an incidental finding in radiological imaging. Symptomatic patients are presented with a slowly growing mass involving the jaws commonly in mandible bone and can attain a large size with the passage of time. It can cause facial deformity if left untreated. We present such a case of Cemento-ossifying fibroma involving the right hemi-mandible bone, and its radiological imaging findings, including X-ray (OPG), CT scan, and Histopathology.

Background and aims: It was investigated whether there is a relationship between advanced atherosclerosis of the carotid artery and cancer. Method: The carotid Total Plaque Area (TPA), the maximum plaque thickness, and the cardiovascular risk based on Framingham calculator using body-mass-index were determined in healthy subjects using ultrasound. We compared the outcome in subjects with advanced atherosclerosis of the carotid artery (type III-IV b finding) with and without statin treatment. The follow-up was collected as part of occupational health check-ups. Result: In 4207 healthy men aged 35-65 years (50±8 years) we found 578 subjects with advanced atherosclerosis of the carotid artery (type III-IV b finding). A follow-up was available for 566 (97.9%) subjects. The average follow-up time was 48 months (range 0 to 139 months). Ten subjects were excluded because of missing data on treatment. A total number of 230 subjects was treated with a statin, 326 received no statin. Within the group of these subjects (54±6 years), 33 men died (15 cancer, 4 strokes, 11 heart attacks, 1 COPD, 1 sepsis, 1 cirrhosis of the liver). In the group with CVD death, two subjects were treated with a statin, 13 were untreated. In the group with cancer death, two subjects were treated with a statin, 13 were untreated. The death rate because of cancer and CVD was 1.7% for the treated subjects and 8.0% for the untreated subjects. In the group with low risk (n= 1890), six men died (2 traffic accidents, 1aneurysm bleeding, 2 cancer, 1 unclear, a follow-up examination has been completed for 43.9% (n= 830) of the subjects, mean follow-up time of 65 months (0-137 months). One man died (Parkinson) within the group with intermediate risk. In this group (n= 482) a follow-up examination has been completed for 55% (n= 265) with a mean follow-up time of 55 months (total range: 0-130 months). In the reference group (no atherosclerosis; n= 1257) follow-up has been completed in 38.3% (n= 482) with a mean follow-up time of 60 (0-145) months and nobody died. In 3203 healthy women aged 35-65 years nobody died of cancer. Conclusion: The development of cancer in men with advanced atherosclerosis of the carotid artery appears to be noticeable. The question of whether there is a causal relationship requires further investigations.
