Chronic aspiration is a cause of life-threatening respiratory complications and repeated hospital admissions, particularly in children with neurological disabilities. Determining the source of aspiration is important for optimizing treatment. This report describes a simple technique to demonstrate salivary aspiration during fibreoptic bronchoscopy. A child with a history of recurrent pneumonia ...
The electrocardiographic (ECG) signal is a transthoracic manifestation of the electrical activity of the heart and is widely used in clinical applications. This chapter describes an unbiased linear adaptive filter (ULAF) to attenuate high-frequency random noise present in ECG signals. The ULAF does not contain a bias in its summation unit and the filter coefficients are normalized. During the a...
Noradrenaline (NA) from the locus coeruleus and GABA from intracortical nonpyramidal cells exert strong influences on cortical activity. To assess possible interaction between the two, the effects of noradrenergic agonists on spontaneous GABAergic IPSCs as well as on the activity of identified GABAergic cell types were investigated by in vitro whole-cell recordings from the frontal cortex of 18...
BACKGROUND Determination of urinary free catecholamine and total (i. e., free plus conjugated) metanephrine excretion is considered the most clinically sensitive biochemical test for pheochromocytoma. In this study, we evaluated new immunoassay methods for the measurement of these analytes for potential drug-based interference. METHODS Urine samples collected from patients on a variety of med...
The product of the Drosophila embryonic lethal abnormal visual system is a conserved protein (ELAV) necessary for normal neuronal differentiation and maintenance. It possesses three RNA-binding domains and is involved in the regulation of RNA metabolism. The long elav 3'-untranslated region (3'-UTR) is necessary for autoregulation. We used RNA-binding assays and in vitro selection to identify t...
INTRODUCTION This study analyzed the association between psychomotor development and socio-demographic and family stimulation factors in 3-year-old children from San Carlos de Bariloche. POPULATION AND METHODS A total of 152 apparently healthy children aged 35-37 months old who attended municipal and private kindergartens were evaluated. Children's performance in personal-social, fne motor, l...
Introduction. Pharyngoesophageal perforation secondary to barotrauma is a rare phenomenon that can have serious complications if identified late. It is challenging to detect due to nonspecific symptoms. We present a case in which detection proved difficult leading to delayed diagnosis. Case Report. A 27-year-old mechanic presented with haemoptysis, dysphonia, and odynophagia after a car tyre ex...
We report six months old infant with a history of recurrent wheeze, admitted for foreign body aspiration like presentation, where fibreoptic bronchoscopy revealed the diagnosis of tracheobronchomalacia.
We studied the size 4 laryngeal mask airway (LMA) to test the hypothesis that oropharyngeal leak pressure and fibreoptic position improves with increasing cuff volume. After LMA insertion, 50 anaesthetized adult patients had the cuff inflated in 5-ml increments to 40 ml. Oropharyngeal leak pressure was optimal at 15 ml and decreased at higher volumes. The fibreoptic position was optimal at 0-20...
