Abstract Background: The analysis of risk factors for predicting related complications has not been reported to date. Objective: This study aims to investigate the risk factors of related complications of percutaneous transluminal septal myocardial ablation (PTSMA) for hypertrophic obstructive cardiomy...

Disability as a determinant of fatigue in MS patients

Arq. neuropsiquiatr; 77 (4), 2019
ABSTRACT Fatigue is one of the most frequent and disabling symptoms in multiple sclerosis (MS). Central, psychological, and peripheral factors may contribute to the occurrence of fatigue. Objectives: The current study aimed to evaluate potential fatigue determinants in patients with relapsing-remitting ...

Validation of multiplex PCR for the diagnosis of acute bacterial meningitis in culture negative cerebrospinal fluid

Arq. neuropsiquiatr; 77 (4), 2019
ABSTRACT This study evaluated the operational characteristics of the multiplex polymerase chain reaction (PCR) for cerebrospinal fluid (CSF) from patients with cellular and biochemical characteristics of acute bacterial meningitis and positive or negative CSF cultures. Methods: Multiplex PCR was perform...

A comparative study of osteopontin and MMP-2 protein expression in peripheral and central giant cell granuloma of the jaw

Abstract Introduction: Oral peripheral and central giant cell granulomas are lesions with little-known etiology and pathogenesis. Objective: The aim of this study was to compare matrix metalloproteinases-2 and osteopontin protein expression in the multinucleated giant cells and mononuclear cells of the...

Automated cortical auditory evoked potentials threshold estimation in neonates

Abstract Introduction: The evaluation of cortical auditory evoked potential has been the focus of scientific studies in infants. Some authors have reported that automated response detection is effective in exploring these potentials in infants, but few have reported their efficacy in the search for thre...

Body balance at static posturography in vestibular migraine

Abstract Introduction: Migraine is one of the most frequent and incapacitating headaches, with a high degree of impairment in quality of life. Its association with vestibular symptoms is common, including imbalance and postural instability. Objective: To evaluate the body balance of patients with vesti...

The role of intraoperative narrow-band imaging in transoral laser microsurgery for early and moderately advanced glottic cancer

Abstract Introduction: Trans-oral laser microsurgery is an established technique for the treatment of early and moderately advanced laryngeal cancer. Objective: The authors intend to test the usefulness of narrow-band imaging in the intraoperative assessment of the larynx mucosa in terms of specifying ...

Cholesteatoma labyrinthine fistula: prevalence and impact

Abstract Introduction: Labyrinthine fistula is one of the most common complications associated with cholesteatoma. It represents an erosive loss of the endochondral bone overlying the labyrinth. Reasons for cholesteatoma-induced labyrinthine fistula are still poorly understood. Objective: Evaluate pati...

Wideband acoustic absorbance in children with Down syndrome

Abstract Introduction: Tympanometry is currently the most frequently used tool for assessing the status of the middle ear, commonly assessed using a single 226 Hz tone. However, the use of the Acoustic Immittance Measures with a wideband stimulus is a promising high-resolution evaluation, especially in ...
