OBJECTIVE To describe a new device for home treatment of urinary incontinence (UI) by comparing 3 conservative techniques and monitoring compliance and performance. METHODS Thirty-two patients with UI were allocated to 1 of 3 intervention groups: pelvic floor muscle exercises (PFME; n=11) alone; PFME combined with biofeedback (n=10); or PFME combined with(More)
INTRODUCTION Neuropathic pain (NP) is a chronic pain modality that usually results of damage in the somatosensory system. NP often shows insufficient response to classic analgesics and remains a challenge to medical treatment. The transcranial direct current stimulation (tDCS) is a non-invasive technique, which induces neuroplastic changes in central(More)
Antimicrobial peptides (AMPs) are a promising solution to face the antibiotic-resistant problem because they display little or no resistance effects. Dimeric analogues of select AMPs have shown pharmacotechnical advantages, making these molecules promising candidates for the development of novel antibiotic agents. Here, we evaluate the effects of(More)
Endoscopic augmentation of the esophagogastric junction (EGJ) with polymethylmethacrylate (PMMA) has been reported in an experimental short-term study. We assessed whether endoscopic augmentation of the EGJ with PMMA is durable, safe, and efficacious after 6 months in mini-pigs. Ten mini-pigs were studied under anesthesia. After a pilot study in two(More)
OBJECTIVE To determine the prevalence and factors associated with oropharyngeal aspiration in pediatric patients submitted to mechanical ventilation and endotracheal intubation. DESIGN Prospective cross-sectional study. SETTING Four pediatric intensive care units. PATIENTS Fifty infants and children with endotracheal intubation submitted to mechanical(More)
BACKGROUND AND PURPOSE Poor sleep is commonly associated with alterations in pain perception. However, there is a lack of studies that address work-associated sleep restriction (SR) and changes in non-nociceptive perception and autonomic responses after work-induced SR. METHODS This study was performed with 19 medical students after a normal-sleep night(More)
We describe a case series of 35 patients with either benign (14) or malignant (21) tracheal stenosis who were treated using a novel silicone stent, the HCPA-1, designed to prevent migration. Between March 2001 and September 2008, 13 women and 22 men received 41 HCPA-1 stents. The median duration of stenting in benign cases was 457 days (range, 4-2,961(More)
Quantitative sensory testing (QST) is defined as the determination of thresholds for sensory perception under controlled stimulus. Our aim was to validate a new QST device for Brazilian sample. In 20 healthy adults, thermoalgesic thresholds were assessed using a QST prototype (Heat Pain Stimulator-1.1.10; Brazil). A 30 × 30 mm(2) thermode with a 1°C/s(More)
Subglottic stenosis (SGS) is defined as the narrowing of the lower larynx. Difficulties in the management of subglottic stenosis, especially in the pediatric population, justify the development of experimental models. The objective of this study was to compare the two methods of experimental subglottic stenosis induction. Twenty-three dogs were randomly(More)
Our objective was to evaluate experimental induction of empyema in rats by intrapleural inoculation of Staphylococcus aureus by means of thoracentesis with pleural pressure monitoring. Forty female albino Wistar rats, anesthetized with droperidol and fentanyl, underwent intrapleural inoculation of a 0.2-ml solution. Group I (N=25) received 1010(More)
