ABSTRACT

BACKGROUND: Central nervous system tumours comprise a heterogeneous group of neoplasms with great histological diversity. Despite the rising prevalence of these tumours in developing countries, some places like Mexico and Latin America have no representative studies that show the real impact of these tumours in our population. OBJECTIVE: To describe the characteristics of the primary and secondary tumours of the central nervous system in the last 20 years in a Mexican institution. MATERIAL AND METHODS: Patients with histopathological diagnosis from 1993 to 2013 in our institution, grouping them according to WHO classification 2007, characterising them by age group, gender, and anatomical location. RESULTS: There were a total of 511 tumours of the central nervous system. Of those, 292 were women and 219 men, with a ratio 1.3: 1, and a mean age of 49.3 years. Tumours with higher prevalence were: Meningeal tumours, 171 (33%), followed by neuroepithelial, 121 (24%). Astrocytoma had the highest prevalence in paediatric patients, whereas in those older than 20 years it was the meningioma. The supratentorial location was the most involved. CONCLUSION: This is the first study of a series of cases in Mexico that is performed by taking into account benign and malignant tumours of the central nervous system, with patients of all age groups with a range of 20 years. While this work only represents a retrospective analysis of an institution, it can be a strong indication of the epidemiology of these tumours in our environment.

ABSTRACT

This paper reports the testing of a lightweight wearable stereoscopic display during neuroendoscopies and endoscope assisted neurosurgeries. The viewers tested were a binocular (for the surgeon) and a monocular system (for the instrumenting nurse), whose optics are specially designed for wearable, portable applications and comprise a color corrected refractive magnifying system.

ABSTRACT

A la calcificación de un hematoma subdural crónico en el cráneo que cubre la mayor parte de la superficie cortical de uno o ambos hemisferios cerebrales se le ha dado el nombre de "cerebro blindado". El diagnóstico de esta entidad se sospecha por la clínica y se confirma con estudios de imagen. El tratamiento aún es controvertido. E presente caso describe un paciente de 26 años de edad con antecedente de traumatismo craneoencefálico y crisis convulsivas generalizadas recurrentes. Veintidós horas previas a su ingreso tuvo una crisis convulsiva tónico-clónica generalizada que ocasionó caida de su propia altura y traumatismo craneoencefálico. Fue encontrado inconsciente con pupilas midriáticas, postura de descerebración y respuesta plantar extensora bilateral por lo que fue trasladado al Hospital Español donde fue recibido con una calificación de 4 en la escala de Glasgow. La TAC mostró un hematoma epidural fronto-parietal izquierdo con gran efecto de masa con desplazamiento de estructuras de la línea media con herniación subfacial hemorragia subaracnoidea e intraventricular así como contusión hemorrágica temporoparietal derecha sin efecto de masa. Fue intervenido con drenaje de hematoma epidural y del hematoma subdural calcificado con exéresis de membranas calcificadas. Su evolución fue tórpida sin mejoría de condición preoperatoria falleció a la semana La cirugía está indicada cuando el déficit neurológico se instala en forma aguda. En cambio en el paciente asintomático la cirugía no necesariamente corrige la deformidad cerebral debido a la atrofia cerebral secundaria. Se realizó una revisión de la literatura.
