ABSTRACT
Los fenómenos de despolarización cortical propagada (CSD y CSD-like) son despolarizaciones celulares que se extienden en forma de onda y están implicados en la progresión de las lesiones en pacientes con ictus y traumatismo craneoencefálico (TCE). Son detectables en el registro de electrocorticografía (ECoG). Experimentalmente inducen hipoxia cerebral e incrementa la permeabilidad de la barrera hematoencefálica. Objetivos: Determinar la frecuencia y duración de estos episodios en pacientes con TCE o infarto maligno de la arteria cerebral media (IMACM) que requieran craniectomía. Material y métodos: 20 pacientes a los que se les colocó, en el córtex perilesional, una tira de seis electrodos. Análisis del número y la duración de los episodios de CSD registrados. Resultados: En cuatro, de los ocho registros de ECoG analizados, se identificaron episodios de CSD o CSD-like de duración y frecuencia variable. Conclusiones: Se detectan frecuentemente episodios de CSD y CSD-like en pacientes con IMACM y TCE (AU)
The phenomena of cortical spreading depolarization (CSD and CSD-like phenomena) are cellular depolarization waves involved in the progression of lesions in patients with stroke and traumatic brain injury (TBI). Which are detected by an electrocorticographic (ECoG) recording. Experimentally, CSD induces cerebral hypoxia and increases the permeability of the blood-brain barrier. Objectives: To determine the frequency and duration of CSD episodes in patients with TBI and malignant middle cerebral artery infarction (MMCAI) requiring craniectomy. Material and methods: 20 patients were included. A strip of 6 electrodes was placed in the perilesional cortex. Analysis of the number and duration of CSD episodes in the ECoG recording was performed. Results: In four, of the eight ECoG recordings that was fully analyzed, CSD or CSD-like phenomena were identified with a variable frequency and duration. Conclusions: Episodes of CSD and CSD-like phenomena are frequently detected in patients with MMCAI and TBI (AU)

We report an interesting case of delayed frontal abscess caused by a penetrating nonmissile foreign body, a bamboo stick in a 1.5-year-old male child. A parietal craniotomy was performed, and the brain abscess was resected along with the foreign body without any damage to the surrounding brain tissue. He also received the appropriate antibiotics. The child made a good recovery.
