- Posterior Reversible Encephalopathy Syndrome in a Pediatric Intensive Care Unit: A Case SeriesPublication . Teixeira, Beatriz; Gonçalves, Vera; Cardoso, Ana Lúcia; Ribeiro Fernandes, Sofia; Rocha, Liliana; Garrido, Cristina; Sarmento, AlziraPosterior reversible encephalopathy syndrome (PRES) is a reversible clinical-radiographic abnormality. It is characterized by headache, altered consciousness, seizures, and visual disruption, in addition to characteristic white matter edema lesions in the parieto-occipital areas of the brain. Early detection and treatment are crucial to prevent irreversible damage. This paper presents the cases of three patients with PRES with concurrent diagnoses of glomerulonephritis, Guillain-Barré syndrome, and sickle cell disease. All patients experienced systemic hypertension, seizures, and altered consciousness. All patients were admitted to intensive care for decreased level of awareness or status epilepticus requiring invasive mechanical ventilation. Anticonvulsants and antihypertensive therapy were essential. No chronic complications were recorded.
- Acute Fulminant Cerebral Edema in a Child With Suspected MeningoencephalitisPublication . Monteiro, Sara; Teixeira, Beatriz; Fraga, Carolina; Dias, Andreia; Cardoso, Ana Lúcia; Meireles, Daniel; Sarmento, Alzira; Ferreira, Paula Regina; Silva, João; Garrido, Cristina; Gonçalves, SaraAcute fulminant cerebral edema (AFCE) is a recently identified encephalitis type associated with significant morbimortality. Described as rare, limited data exists on its early detection and treatment. This paper describes a case of AFCE that progressed to unresponsive intracranial hypertension. A previously healthy four-year-old boy presented with fever, myalgias, and neurological symptoms. Diagnostic assessments showed cerebrospinal fluid abnormalities, and despite medical interventions, his condition deteriorated rapidly and developed severe cerebral edema and herniation within 24 hours. A decompressive craniectomy was attempted to decrease intracranial pressure, without success. This case emphasizes the urgency of early AFCE recognition and effective management strategies given its severe prognosis, aiming to improve understanding and spur further research
