OBJECTIVE To use an audiovestibular test battery to evaluate patients with leukoaraiosis in order to investigate the relationship between vertigo and dizziness and leukoaraiosis. DESIGN Retrospective study. SETTING Tertiary university hospital. Patients A total of 18 elderly patients with vertigo and dizziness and with leukoaraiosis confirmed by magnetic resonance imaging (hereafter, leukoa...

BACKGROUND There is conflicting evidence about the relationship between the dose of enteral caloric intake and survival in critically ill patients. The objective of this systematic review and meta-analysis is to compare the effect of lower versus higher dose of enteral caloric intake in adult critically ill patients on outcome. METHODS We reviewed MEDLINE, EMBASE, Cochrane Central Register of...

Rats were fed with food of different caloric densities by addition of kaolin or groundnut oil to the normal food powder. The food intake, caloric intake and body weights were noted. These observations were compared before and after bilateral destruction of mid-dorsal caudate nucleus. The food intake before caudatal lesion varied appropriately with the caloric density of food thus maintaining ca...

Sound and skull-tap induced vestibular evoked myogenic potentials (VEMP) were studied in a 43-year-old man following inferior vestibular neurectomy. Surgery was performed because of a small acoustic neuroma. Postoperative caloric testing suggested sparing of superior vestibular nerve function on the operated side. In response to sound stimulation there were no VEMP on the operated side, irrespe...

OBJECTIVE To assess the frequency of cardiovascular risk factors in the rural community of Cavunge, in the Brazilian state of Bahia. METHODS A cross-sectional study was carried out with 160 individuals (age>19 years) randomly drawn from those listed in the population census of the Cavunge Project. The following parameters were studied: arterial hypertension, dyslipidemia, diabetes, obesity, s...

Exposure misclassification constitutes a major obstacle when developing dose-response relationships for risk assessment. A non-differentional error results in underestimation of the risk. If the degree of misclassification is known, adjustment may be achieved by sensitivity analysis. The purpose of this study was to examine the full magnitude of measurement error in determining the prenatal exp...

dietary fatty acids) in the production of irreversibly cross-linked proteins and nucleic acids. A number of testable hypotheses emerge (e.g. the effects of caloric overabundance on rate of cross-linking); these turn out to be stimulating for serious laboratory and clinical investigators. The major difficulty with this book is that too little is known about aging to permit real integration of ex...

IMPORTANCE Dizziness and imbalance are common clinical problems, and accurate diagnosis depends on determining whether damage is localized to the peripheral vestibular system. Vestibular testing guides this determination, but the accuracy of the different tests is not known. OBJECTIVE To determine how well each element of the vestibular test battery segregates patients with normal peripheral ...
