    Lisencefalia y epilepsia en pediatría
    (2007) Hernández Chávez, Marta Isabel; Bolte Marlhoz, Lillian; Mesa Latorre, Tomás; Escobar Henríquez, Raul; Mellado Sagredo, Cecilia; Huete Lira, Isidro
    Background: Lissencephaly is a brain malformation caused by defective neuronal migration and characterized by epilepsy and severe psychomotor retardation, with high mortality. Objective: Describe the clinical presentation, neuroradiologic characteristics and evolution of 9 children with lissencephaly. Results: 9 children (4 males) were controlled between 1999 and 2007. The diagnosis was made during the neonatal period in 4 patients; 3 cases presented seizures and microcephaly, while 1 newborn had a prenatal ultrasonography showing cerebral malformation. The diagnosis was made during the first year of life in 5 patients; 4 cases had epilepsy, severe psychomotor retardation and microcephaly, while 1 child had macrocephaly. During follow-up period, 8/9 children had catastrophic epilepsy and severe psychomotor retardation. Conclusions: Lissencephaly is a pathology with bad prognosis, usually diagnosed during the first year of life. Symptoms include refractory epilepsy and severe psychomotor delay. It is important to complete the evaluation with genetic studies and high - resolution neuroimaging, in order to perform an early diagnosis, predict evolution and offer genetic counsil. © 2008 Sociedad Chilena de Pediatría.

    Síndrome del creciente temporal. Reporte de un caso y revisión de la literatura
    (2004) Mery C, V.; Mellado T., Patricio; Valenzuela Mangini, Raúl; Luco Franzoy, Cristián; Huete Lira, Isidro
    The temporal crescent syndrome or half-moon syndrome is a rare mono ocular retrochiasmatic visual field defect that can be correlated to a lesion along the contralateral parieto-occipital sulcus. This field defect may be missed in automated perimetry. We report a 45 years old man, consulting for sudden loss of the peripheral temporal field in his right eye. The magnetic resonance imaging and the spectroscopy studies confirmed an ischemic lesion on the left anterior occipital cortex. Control imaging studies six months later did not show changes in the lesion (Rev Méd Chile 2004; 132: 1523-6).
