Higher positive identification of malignant CSF cells using the cytocentrifuge than the Suta chamber

Arq. neuropsiquiatr; 74 (10), 2016
ABSTRACT Objective To define how to best handle cerebrospinal fluid (CSF) specimens to obtain the highest positivity rate for the diagnosis of malignancy, comparing two different methods of cell concentration, sedimentation and cytocentrifugation. Methods A retrospective analysis of 411 CSF reports. ...

The relevance of trunk evaluation in Duchenne muscular dystrophy: the segmental assessment of trunk control

Arq. neuropsiquiatr; 74 (10), 2016
ABSTRACT The aim was to describe trunk control in ambulant and non-ambulant patients with Duchenne muscular dystrophy (DMD). We conducted a cross-sectional analysis of a sample of 50 DMD patients, (M age = 16.7 years) who underwent the Segmental Assessment of Trunk Control (SATCo). A seven-level scale of...

Working memory and left medial temporal cortical thickness

Arq. neuropsiquiatr; 74 (10), 2016
ABSTRACT Objective To perform a pilot study to investigate the association between working memory and cortical thickness in a sample of attention deficit/hyperactivity disorder (ADHD) children. Methods Seventeen children aged 7-10 years diagnosed with ADHD and 16 healthy children underwent a magnetic r...

Red blood cells in cerebrospinal fluid as possible inhibitory factor for enterovirus RT-PCR

Arq. neuropsiquiatr; 74 (10), 2016
ABSTRACT The presence of hemoglobin in samples are considered an important inhibitory factor for polymerase chain reaction (PCR). The aim of this study was to examine the influence of red blood cells (RBC)s in cerebrospinal fluid (CSF) as an inhibitory factor to reverse transcription polymerase chain rea...

Autonomic thermoregulatory dysfunction in neurofibromatosis type 1

Arq. neuropsiquiatr; 74 (10), 2016
ABSTRACT Objective Neurofibromatosis type 1 (NF1) causes neural and cutaneous disorders and reduced exercise capacity. Exercise/heat exposure increasing internal temperature must be compensated by eccrine sweat function and warmed skin vasodilation. We suspected NF1 could adversely affect eccrine sweat...

Patient age does not affect mefloquine concentrations in erythrocytes and plasma during the acute phase of falciparum malaria

Braz. j. infect. dis; 20 (5), 2016
Abstract Objective To evaluate whether patient age has a significant impact on mefloquine concentrations in the plasma and erythrocytes over the course of treatment for uncomplicated falciparum malaria. Methods A total of 20 children aged between 8 and 11 years and 20 adult males aged between 22 and 41...

Serum levels of vancomycin: is there a prediction using doses in mg/kg/day or m2/day for neonates?

Braz. j. infect. dis; 20 (5), 2016
Abstract Coagulase-negative Staphylococcus has been identified as the main nosocomial agent of neonatal late-onset sepsis. However, based on the pharmacokinetics and erratic distribution of vancomycin, recommended empirical dose is not ideal, due to the inappropriate serum levels that have been measured ...

Molecular epidemiology of coagulase-negative bloodstream isolates: detection of Staphylococcus epidermidis ST2, ST7 and linezolid-resistant ST23

Braz. j. infect. dis; 20 (5), 2016
Abstract The mechanisms contributing to persistence of coagulase-negative staphylococci are diverse; to better understanding of their dynamics, the characterization of nosocomial isolates is needed. Our aim was to characterize phenotypic and molecular characteristics of Staphylococcus epidermidis and Sta...

Antimicrobial susceptibility of Brazilian Clostridium difficile strains determined by agar dilution and disk diffusion

Braz. j. infect. dis; 20 (5), 2016
Abstract Clostridium difficile is a leading cause of diarrhea in hospitalized patients worldwide. While metronidazole and vancomycin are the most prescribed antibiotics for the treatment of this infection, teicoplanin, tigecycline and nitazoxanide are alternatives drugs. Knowledge on the antibiotic susce...
