Introduction. There are tools to quantitatively study the volume of the hippocampus. Such study would help to complement, more objectively and precisely, structural alterations that may be associated with the data obtained from electroencephalograms. Material and methods. Seventeen patients, between 3 and 11 years of age, with diagnosis of first-time seizures and from whom magnetic resonance studies and electroencephalograms were available, were analyzed. Results:.The left temporal lobe was involved in 3 patients, of whom 1 (5%) was found to be normal in the magnetic resonance and 2 (11%) abnormal with diagnoses of venous angioma and cortical atrophy. No significant difference was found between the two groups for the results obtained with resonance (Student p value: 0.6) and those obtained with electroencephalography (Student p value: 0.3). Electroencephalographic alterations in the frontal region were observed in 8 (47%) patients, 4 (23%) predominantly left, 1 (5%) right, and 3 (17%) bilateral; of those, in 5 (29%) cases the resonance was normal, one had left temporal atrophy, one diagnosis of meningitis, and one more of medulloblastoma. Discussion. In the remaining 3 (17%) patients we found generalized cortical involvement in the electroencephalogram, but resonance found one normal study, one suprasellar ependymoma, and one patient with agenesis of the corpus callosum. Conclusion. it was not possible to show a statistically significant value that could relate the results obtained by magnetic resonance with those obtained by electroencephalography.

Objective. Know the effective dose of radiation (mSv) received by patients hospitalized in an intensive care ward, determine if it is greater than that received by patients in standard care areas and if there is any relationship with different variables such as number of studies performed, duration of hospital stay, and number of doctors attending to the patients. Material and methods. Approximate calculation of radiation depending on the number of studies with a radiation risk calculator; it is acknowledged that this calculation will be only approximate. A sample of 100 patients was obtained, of whom 72 formed the control group (patients in standard care areas) and 28 were hospitalized in an intensive care ward. Result. We observed an association of 9% in intensive care patients and 15% in standard care patients in terms of dose of radiation. The intensive care patients received, on average, 59% more radiation than standard care patients: 15.5 mSv vs. 6.5 mSv, respectively. Conclusion. Based on the results, we could not prove an association between number of studies performed, number of attending physicians, or days of hospitalization and doses of radiation received.

Introduction. Chest injuries are one of the leading causes of morbidity and mortality. Proper description of findings is important and the chest x-ray is the preferred imaging method. Objective. The aim of this study is to review the spectrum of lesions that occur in the chest, detected by means of simple x-rays, in polytraumatized patients. Material and methods. An observational, descriptive, cross-sectional study of 72 patients (37 women and 35 men between 15 and 70 years of age) with polytrauma caused by automobile accidents. All underwent chest x-rays on admission. Results. We observed that 21 patients presented some radiological alteration associated with trauma and the most common injuries were costal fractures 44% (13 patients). The second most common radiological alteration was pulmonary contusion with 27% (8 patients), and pneumothorax was observed in 7% of the cases. Discussion. There was a distribution of injuries similar to that described in the specialized literature in terms of thoracic trauma. The anteroposterior x-ray is highly useful because it can be taken without altering the patient's mobility. Conclusion. The chest x-ray plays an important role in the initial evaluation of a polytraumatized patient and is a rapid, simple, and practical imaging method. It provides important information on the structures of the rib cage. [ABSTRACT FROM AUTHOR]
