A consecutive, unselected series of 82 patients with epidural hematoma treated between 1973 and 1980 is presented. Forty-one patients were managed before the advent of computerized tomography (CT) and the other 41 after this neuroradiological method was available. Mortality and disability rates which were 29.2% and 31.7% during the pre-CT period decreased… (More)
The case of a neonate with an extradural hemorrhage in the left posterior fossa, the result of trauma at birth, is reported. The routine axial transverse CT scan did not detect the exact preoperative location of the clots in the extradural space of the posterior fossa. Good recovery was achieved following the operation.
The authors describe four cases of subependymoma studied with computed tomography (CT) and review 18 previously reported cases in an attempt to define the most characteristic CT presentation of this rare, benign tumor. Subependymoma usually appears as an isodense, or even hypodense, intraventricular tumor on plain CT scan and shows minimal or no enhancement… (More)
The cases of 11 patients with hydrocephalus secondary to cerebral cysticercosis are analyzed. Most of the patients had suffered from epilepsy before they developed hydrocephalic symptoms, and computerized tomography showed that infestation of the parenchyma coexisted with ventricular or cisternal colonization. In four cases, the parasitic vesicles… (More)
The case of a woman with a large, mixed, cerebral arteriovenous malformation mainly involving the posterior fossa and producing a noncommunicating hypertensive hydrocephalus is reported. Relief of ventricular enlargement by means of a cerebrospinal fluid shunt unexpectedly resulted in stupor and Parinauds' syndrome. These complications were completely… (More)
Eighteen children with severe head injuries and diffuse brain swelling were studied. They were separated into two groups based on the computed tomography (CT) findings. Seven patients had small ventricles in the normal location and small or absent cisterns. Eleven had these signs plus small deep-seated intraparenchymal hemorrhagic foci and/or… (More)
OBJECTIVE The objective of this study is to evaluate allergy prevalence to latex proteins in health care workers at the Laboratory and Surgery Room of Hospital CIMA Chihuahua. METHODOLOGY AND RESULTS A thorough clinical chart was recorded for all health care workers studied: hematic biometry, total IgE by ELISA method, specific IgE to latex antigen by… (More)
Neural tube defects are common birth defects, the frequency of which appears to be reduced by maternal supplementation and/or fortification of folic acid. Latin Americans have a high incidence of neural tube defects. We surveyed the dietary intake of Honduran women of childbearing age using a 24-hour dietary recall questionnaire in inner-city, town, and… (More)
Seven cases of symptomatic spinal hemangiomas are discussed. Special emphasis is given to a patient in whom pre-operative embolization was necessary. A marked reduction in the blood supply was achieved, with the result that the subsequent laminectomy was carried out without great difficulty.
