Título : Congenital brain infections Tipo de documento : documento electrónico Autores : Feliza Restrepo Restrepo, ; Andrés Ignacio Arbeláez Medina, Fecha de publicación : 2014 Títulos uniformes : Topics in Magnetic Resonance Imaging: TMRI Idioma : Inglés (eng) Palabras clave : Pediatric intracranial congenital infections cytomegalovirus HIV toxoplasmosis rubella herpes Resumen : Pediatric congenital intracranial infections are a group of different and important entities that constitute a small percentage of all pediatric infections. The causal factors and clinical presentations are different in children compared with adults. They require early recognition because delay diagnosis and initiation of treatment may have catastrophic consequences. Despite improvements in prenatal screening, vaccine safety, and antibiotics, infections of the central nervous system remain an important cause of neurological disabilities worldwide. This article reviews the most common congenital infections and their imaging findings.

Título : Noncongenital central nervous system infections in children: radiology review Tipo de documento : documento electrónico Autores : Andrés Ignacio Arbeláez Medina, ; Feliza Restrepo Restrepo, Fecha de publicación : 2014 Títulos uniformes : Topics in Magnetic Resonance Imaging: TMRI Idioma : Inglés (eng) Palabras clave : Pediatric CNS infections complications of CNS infections complicated meningitis pediatric neuroimaging Resumen : Infections of the central nervous system (CNS) are a very common worldwide health problem in childhood with significant morbidity and mortality. In children, viruses are the most common cause of CNS infections, followed by bacterial etiology, and less frequent due to mycosis and other causes. Noncomplicated meningitis is easier to recognize clinically; however, complications of meningitis such as abscesses, infarcts, venous thrombosis, or extra-axial empyemas are difficult to recognize clinically, and imaging plays a very important role on this setting. In addition, it is important to keep in mind that infectious process adjacent to the CNS such as mastoiditis can develop by contiguity in an infectious process within the CNS. We display the most common causes of meningitis and their complications.

To gain further knowledge on the preclinical phase of Alzheimer’s disease, we sought to characterise structural and functional MRI, CSF, and plasma biomarkers in a cohort of young adults carrying a high-penetrance autosomal dominant mutation that causes early-onset Alzheimer’s disease.

Consenting participants also had lumbar punctures and venepunctures. Outcome measures were task-dependent hippocampal or parahippocampal activations and precuneus or posterior cingulate deactivations, regional grey matter reductions, CSF Aβ1–42, total tau and phospho-tau181 concentrations, and plasma Aβ1–42 concentrations and Aβ1–42:Aβ1–40 ratios.
