Introduction: There are no studies that evaluate the measurements of the distances between the grooves that demarcate the Paracentral Lobule (PCL) in literature. This study seeks to contribute to the knowledge regarding the anatomy of the PCL, conducting an analysis of morphometric measurements in this region and its correlation with the paracentral sulcus, marginal branch of the cingulate and central sulci. Methods: 42 hemispheres were evaluated, 22 from the right and 20 from the left hemisphere. Using a digital caliper rule Western ®, model Dc -6, measurements of the size of Paracentral Lobe in the sagittal axis and coronal axis were made, in addition to measures of the Central Sulcus to the Paracentral Sulcus (motor area) and Central Sulcus to Marginal Branch of the Cingulate Sulcus (somesthetic area), comparing the prevalence of each of these lengths between hemispheres. Results: The average length between the Paracentral Sulcus and the Central Sulcus was 24.49 cm (14.2 to 38.6 cm) in the right hemisphere and 25.50 cm (11.7 to 37.0 cm) in the left. As between the Central Sulcus and the Marginal Branch of the Cingulate Sulcus was in average 10.03 cm (2.6 to 22.7 cm) in the right and in the left PCL 9.17cm (2.6 to 22.7 cm). In the right hemisphere, 19 samples (86,4%) presented greater length of the motor area than somesthetic, and, in the left hemisphere, 19 samples (95%) had greater length of the motor area. Conclusion:The motor area showed larger size in relation to the sensory area in the analysis of the two hemispheres, while the comparison of other measures between the two hemispheres showed no significance.
Acid-base disturbances are entities caused by the deregulation of the concentration of bicarbonate ions, the concentration of hydrogen ions and the partial pressure of carbon dioxide in the blood. These disturbances modify most cell fuctions when present, damaging the proper functioning of organs. Transversal study based upon data collected from medical records of patients in ICU as seen from August 1 to December 31, 2013 at the (GFR), serum concentratrion of potassium and magnesium and serum levels of creatinine and hemoglobin. The chi-square and Fisher exact test were used to compare the proportions according to the number of cases. For quantitative variables, the analysis of variance (ANOVA) was used and the Kruskal-Wallis test if the Bartlett test presented p<0.05. : The most frequent disorders were primary respiratory alkalosis with 33 (38.4%) cases, 30 (34.9%) of metabolic alkalosis, 13 (15.1%) of metabolic acidosis, 7 (8.2%) did not present acid-base disorders and respiratory acidosis 3 (3.5%). Patients admitted with TBI had respiratory alkalosis as the most common primary disorder, followed by metabolic alkalosis, 16 (47.0%) and 13 (38.2%), respectively. The main disturbances mixed respiratory alkalosis with metabolic alkalosis and respiratory alkalosis with metabolic alkalosis found in 15.12% of patients in each of these combinations. Comparative evaluation of the means of the variables between groups of primary disorders were older (p=0.047), anion gap : Patients who have suffered traumatic brain injury presented as primary disorder more common the respiratory alkalosis and the metabolic alkalosis. Ionic disturbances related to potassium and magnesium showed
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
