The objective of the article is to report the case of three patients with diffuse intrinsic pontine glioma (DIPG) treated with immunotherapy. In particular we report the data related to the treatments' efficacy and tolerance.To achieve this, we review the medical records in the Paediatric Oncology and Haematology Unit of HM Hospitales/Centro Integral Oncológico Clara Campal (CIOCC). We focused on patients diagnosed with DIPG who were administered oncolytic viruses followed by immune checkpoint inhibitors (ICI) (pembrolizumab, anti PD-1) plus a concomitant antiangiogenic agent (bevacizumab).The results we obtained showed the three paediatric DIPG patients studied presented good tolerance, with disease stabilisation for approximately 5 months after immunotherapy. However, subsequent clinical worsening required clinicians to change the patients' treatment.In conclusion, immunotherapy combined with other conventional antineoplastic treatments (chemotherapy, radiotherapy) is postulated as a very promising future therapeutic option. However, further research is warranted in the paediatric population to demonstrate safety and effectiveness.

Modeling absorbed alpha particle dose from diffusing alpha-emitters radiation therapy in changing tissue volumes.

Background: Diffusing alpha-emitters Radiation Therapy ("Alpha DaRT") is a promising new radiation therapy modality for treating bulky tumors. Ra-carrying sources are inserted intratumorally, producing a therapeutic alpha-dose region with a total size of a few millimeter via the diffusive motion of Ra's alpha-emitting daughters. Clinical studies of Alpha DaRT have reported 100% positive response (30%-100% shrinkage within several weeks), with post-insertion swelling in close to half of the cases.

Magnetic resonance imaging (MRI) is frequently used to monitor disease progression in multiple sclerosis (MS). This study aims to systematically evaluate the correlation between MRI measures and histopathological changes, including demyelination, axonal loss, and gliosis, in the central nervous system of MS patients. We systematically reviewed post-mortem histological studies evaluating myelin density, axonal loss, and gliosis using quantitative imaging in MS.

Purpose: The study explores the role of multimodal imaging techniques, such as [F]F-PSMA-1007 PET/CT and multiparametric MRI (mpMRI), in predicting the ISUP (International Society of Urological Pathology) grading of prostate cancer. The goal is to enhance diagnostic accuracy and improve clinical decision-making by integrating these advanced imaging modalities with clinical variables. In particular, the study investigates the application of few-shot learning to address the challenge of limited data in prostate cancer imaging, which is often a common issue in medical research.

Aim of this study was to proof the concept of optimizing the contrast between prostate cancer (PC) and healthy tissue by DWI post-processing using a quadrature method. DWI post-processing was performed on 30 patients (median age 67 years, prostate specific antigen 8.0 ng/ml) with PC and clear MRI findings (PI-RADS 4 and 5).

Persistent post-surgical pain (PPSP) occurs in a proportion of patients following surgical interventions. Research suggests that specific microbiome components are important for brain development and function, with recent studies demonstrating that chronic pain results in changes to the microbiome. Consumption of a high fat, high sugar (HFHS) diet can drastically alter composition of the microbiome and is a modifiable risk factor for many neuroinflammatory conditions.
