Comparison of computerized digital and analog radiography for detection of bronchial pattern in dogs
Background: Analog radiography has been replaced with digital radiography for canine diagnostic imaging in many veterinary clinics. There is no data comparing these modalities in a veterinary clinical setting to detect bronchial pattern signs in dogs. Objectives: In this study, computerized digital radiography (CR) and analog radiography were compared for diagnosis of bronchial pattern in dogs....
massive hemoptysis is one of the most important respiratory emergencies and pulmonary infiltrating diseases are among the rare causes of hemoptysis. bronchial artery embolization (bae) is a safe and effective treatment in these patients. our case was a 45 years old woman with a 7 year history of hodgkin's lymphoma who presented with massive hemoptysis of 20 days duration. ct scan revealed prebr...
Twenty subjects with mild asthma were exposed at rest in a body plethysmograph, to NO2 at 0, 260, 510 and 1,000 micrograms.m3, for 30 min on four separate days. Bronchial responsiveness (histamine inhalation test) was measured after each exposure session. Airway resistance (Raw), thoracic gas volume (TGV) and specific airway resistance (sRaw) were measured before, during and after exposure, and...
Increases in minute ventilation (V'E) have been observed during exacerbations of asthma and in response to administration of histamine. However, it is not yet clear how the breathing pattern is affected, and whether the increase in V'E is found in general. In the present study, the effects of inhalation of histamine on respiratory frequency (fR), tidal volume (VT), V'E, and on functional residu...
Bronchial dosimeters have been designed for adult Chinese males and females for home and mine exposures, which can give the bronchial doses from radon progeny by direct measurements. The bronchial dosimeter for home exposures consists of five 400-mesh wire screens. With a sampling face velocity of 3.3 cm s(-1) for Chinese males and 2.7 cm s(-1) for Chinese females, the deposition pattern on the...
the relationship between mycoplasma pneumoniae (mp) infection and asthma has rarely been explored through examination of airway reactivity. the aim of this study was to determine airway reactivity changes after mp infection in children. first, 106 children were divided into four groups according to the existence of mp infection and/or asthma. then children with only mp belonged to the mp group;...
bronchial asthma is a multifactorial disease whereby both environmental and genetic factors contribute to its aetiology and/or clinical severity. the aim of this study was to examine the association of 22 cytokine gene polymorphism in the macedonian population with bronchial asthma (ba). the sample of the population comprised of 301 normal unrelated individuals and 74 patients with ba. cytokine...
Anthracosis of the lungs is black discoloration of bronchial mucosa that can occlude bronchial lumen and is associated with bronchial anthracofibrosis (BAF). This disease usually presents with a chronic course of dyspnea and or cough in an elderly non-smoker woman or man. In addition, concomitant exposure to dust and wood smoke is the most postulated etiology for anthracosis. Pulmonary function...
We wanted to investigate whether asthmatic subjects change their ventilatory pattern consistently when forced expiratory volume in one second (FEV1) has declined by at least 20% during bronchial histamine challenge, in order to assess whether respiratory pattern analysis can be used to monitor bronchial obstruction continuously. Histamine challenge was performed twice within a four week period,...
