Validation of the Burn Survivor Fear-Avoidance Questionnaire and Its Association With Pain Intensity, Catastrophizing, and Disability.

According to the Fear-avoidance (FA) model, FA beliefs can lead to disability due to avoidance of activities expected to result in pain or further injury. Extensive research on the relationship of FA, pain, catastrophizing, and disability has been generated with patients suffering from chronic neck and back pain, but little research has been conducted with burn survivors. To address this need, the Burn Survivor FA Questionnaire (BSFAQ) was developed (Langlois J, Vincent-Toskin, S, Duchesne, P et al.

Presence of Staphylococcus spp. carriers of the mecA gene in the nasal cavity of piglets in the nursery phase.

The presence of Staphylococcus spp. resistant to methicillin in the nasal cavity of swine has been previously reported. Considering the possible occurrence of bacterial resistance and presence of resistance genes in intensive swine breeding and the known transmissibility and dispersion potential of such genes, this study aimed to investigate the prevalence of resistance to different antibiotics and the presence of the mecA resistance gene in Staphylococcus spp.

Urban Horses As Environmental Bioindicators for Leishmaniasis.

The presence of DNA and anti- spp. antibodies in the serum of 112 healthy horses was investigated by evaluating the physical examination, from a rural society located in the north central region of Paraná. The antigens of , , and were used to perform the indirect enzyme-linked immunosorbent assay, where it was possible to detect the reaction in 27.

Smear layer removal by passive ultrasonic irrigation and 2 new mechanical methods for activation of the chelating solution.

Objectives: The aim of this study was to compare smear layer removal by conventional application (CA), passive ultrasonic irrigation (PUI), EasyClean (EC), and XP-Endo Finisher (XPF), using 17% ethylenediaminetetraacetic acid (EDTA) after chemomechanical preparation, as evaluated with scanning electron microscopy (SEM).

Materials And Methods: Forty-five single-rooted human mandibular premolars were selected for this study. After chemomechanical preparation, the teeth were randomly divided into 5 groups according to the protocol for smear layer removal, as follows: G1 (control): CA of distilled water; G2 (CA): CA of 17% EDTA; G3 (PUI): 17% EDTA activated by PUI; G4 (EC): 17% EDTA activated by EC; and G5 (XPF): 17% EDTA activated by XPF.

Correlation among Root Canal Configuration, Quality of Filling, and Its Sealability.

Objective:  This study aimed to evaluate the existence of possible correlations among root canal configuration, quality of filling, and its sealability.

Materials And Methods:  Sixty human mandibular central incisors were selected for this study. The teeth were prepared with the Profile 04 system up to instrument 35/0.

Thyroid-disrupting effects of chlorpyrifos in female Wistar rats.

Thousands of chemicals are released into the environment daily, arousing great scientific interest because they can influence the overall function of living organisms. The indiscriminate use of pesticides, especially organophosphate, confers important risks to both public and environmental health. Previous studies showed that chlorpyrifos (CPF) acts as an endocrine disruptor.

Residual smear layer after root canal instrumentation by using Niti, M-Wire and CM-Wire instruments: A scanning electron microscopy analysis.

Objective: The purpose of this study was to compare the amount of residual smear layer after root canal instrumentation by using Ni-Ti, M-Wire, and CM-Wire instruments.

Materials And Methods: Seventy-two mandibular incisors were randomly divided into six groups according to the system used: WaveOne (WO), Reciproc (RP), Unicone (UC), ProTaper Next (PN), Mtwo (MT), and HyFlex (HF). Afterward, the specimens were cleaved in the mesiodistal and buccolingual direction for analysis by scanning electron microscopy.

Incidence of ProTaper Universal System Instrument Fractures - A Retrospective Clinical Study.

Objective: The aim of this retrospective clinical study was to evaluate the incidence of ProTaper Universal System instrument fractures, associated with observation of the arch, group of teeth, and root thirds in which these fractures occurred.

Methods: From analysis of charts, clinical record cards and radiographs of endodontic treatments performed by postgraduate students using the ProTaper Universal System at a reference center, a total of 1031 teeth and 2355 canals were analyzed. The general incidence of instrument fractures and their frequency, considering the group of teeth, arch and root thirds, were cataloged and the data obtained were statistically analyzed (Exact Fischer test, with level of significance of 1%).

Surgical treatment of traumatic eventration with polyester button and polypropylene mesh to strengthen the suture technique in equine.

Background: Defects in the abdominal wall of horses have high relapse rate. This is mainly in lateral eventrations and hernias caused by trauma from kicks of other horses or installation structures. The eventration region normally becomes swollen and there may be complications due to intestinal loop incarceration.

Oyster Culinary-Medicinal Mushroom, Pleurotus ostreatus (Higher Basidiomycetes), Growth in Grain-Based Diet Improves Broiler Chicken Production.

Many alternative compounds have been tested to improve poultry performance but few of them have previously used mycelial-colonized substrate to partially replace standard diet in broiler chickens. The objective of this study was to evaluate broiler chicken production, health, and meat sensory characteristics, with partial replacement of the standard diet by Pleurotus ostreatus-colonized substrate. One hundred fifty 1-day-old male Cobb chicks were given standard diet partially replaced by 0, 5, 10, 100, or 200 g·kg⁻¹ of P.

Analysis of an anxiolytic technique applied in 1179 patients undergoing oral surgery.

Aim: The aim of this study was to evaluate the effects of sedation with benzodiazepines in a large population of patients undergoing oral surgery and age-related implications.

Methods: A group of 1 179 consecutive patients undergoing oral surgery in the Dental Clinic of the University of Padua between 2001 and 2003 was evaluated by analysing their anaesthesiological records. The patients were divided into 5 age groups.

The use of the computer in a long-term review of 315 fractures of the proximal end of the femur.

The authors present a computer analysis of 315 fractures of the proximal end of the femur. The data were placed in an M24 computer which had previously been programmed for a recording of traumatological cases. Unstable pertrochanteric fractures are discussed in particular, as well as the results obtained in relation to the type of osteosynthesis used.
