Seasonal recurrent airway obstruction, also known as summer pasture-associated recurrent airway obstruction (SPA-RAO), is a seasonal airway obstructive disease of horses, characterized by clinical exacerbation after exposure to pasture during the summer. Clinical signs usually present in horses during exposure to pastures during turnout in the late spring the summer, although some horses dont develop signs until late summer or early fall. Certain mold spores, grass pollens, and species of grass trigger onset of the disease.
The influence of oral N-acetylcysteine on the exacerbation rate in patients with chronic bronchitis and severe airways obstruction has been studied. Two hundred and forty four patients entered the study during October and November 1983 and took placebo sachets for a run in month. One hundred and eighty one who completed this month satisfactorily were randomised to receive either active (acetylcysteine 200 mg three times a day) or matching placebo sachets for five months in a double blind parallel group study. The two groups were well matched. Patients kept detailed daily symptom diaries and were assessed monthly. At the end of the five months study the outcome in the group taking acetylcysteine appeared a little better, but the differences did not reach conventional levels of statistical significance for the mean (SD) number of exacerbations (2.1 (0.2) for acetylcysteine, 2.6 (0.2) for placebo; p = 0.08); total days taking an antibiotic (13.5 (1.7), 18.0 (2.8); p = 0.17); total days spent in ...
Acute airway obstruction is much more common in infants and children than in adults because of their unique anatomic and physiologic features. Even in young patients with partial airway occlusion, symptoms can be severe and potentially life-threatening. Factors that predispose children to airway com
Acute airway obstruction (AAO) after anterior cervical fusion (ACF) can be caused by postoperative retropharyngeal hematoma, which requires urgent recognition and treatment. However, the causes, evaluation, and appropriate treatment of this complication are not clearly defined. The purpose of this retrospective review of a prospective database was to investigate etiologic factors related to the development of AAO due to postoperative hematoma after ACF and formulate appropriate prevention and treatment guidelines. Cervical spinal cases treated at our academic institutions from 1998 to 2013 were evaluated. Demographic data, including factors related to hemorrhagic tendency, and operative data were analyzed. Patients who developed a hematoma were compared with those who did not to identify risk factors. Cases complicated by hematoma were reviewed, and times until development of hematoma and surgical evacuation were determined. Degrees of airway compromise and patient behavior were classified and evaluated

This analysis was conducted to evaluate the prevalence of airway obstruction among Latino poultry processing workers. Data were collected from 279 poultry processing workers and 222 other manual laborers via spirometry and interviewer-administered questionnaires. Participants employed in poultry processing reported the activities they perform at work. Participants with forced expiratory volume in 1 second (FEV1) or FEV1/forced expiratory volume (FVC) below the lower limits of normal were categorized as having airway obstruction. Airway obstruction was identified in 13% of poultry processing workers and 12% of the comparison population. Among poultry processing workers, the highest prevalence of airway obstruction (21%) occurred among workers deboning chickens (prevalence ratio: 1.75; 95% confidence interval: 0.97, 3.15). These findings identify variations in the prevalence of airway obstruction across categories of work activities ...

INTRODUCTION: Airway disease in PSS is reported to be frequent but its severity and clinical relevance remain unclear. We aimed to assess airway obstruction as defined by pulmonary function test (PFT) in patients with PSS.. METHOD: Among 502 patients followed in a reference center for PSS, 81 (78 females) non smokers who underwent PFTs from 1990 to 2012 were retrospectively evaluated. Airway obstruction (AO) was defined by either FEV1/FVC ,70% of predicted (patent obstruction) or MEF25-75 ,50% of predicted (small airway obstruction) or elevated RV/TLC associated with functional residual capacity ,120% of predicted (hyperinflation). Clinical and chest CT scan characteristics of patients with airway obstruction were compared with normal PFT patients.. RESULTS: Mean age at PSS diagnosis was 53,1 year. Mean disease duration at study was 5.3 year. 73 (90%) patients had respiratory symptoms. 26 patients (32%) had an airway obstruction: 10% a patent obstruction, 15% a small airway obstruction and 7% an ...
If variation in ventilatory drive, both endowed and acquired, determines the extent and quality of adaptation to the hypoxia of high altitude, such variation might also contribute to the variable clinical profile of patients with hypoxic disease at low altitude, such as chronic obstructive pulmonary disease. It has long been known that such patients present a varied clinical picture illustrated by patients presenting at the extreme edges of the spectrum-the pink puffer and blue bloater. More common is the broad range of PaC02 observed with a given degree of severe airway obstruction, indicating that the ventilatory adaptation to severe airway obstruction is quite variable. The presence of intense dyspnea in the eucapnic pink puffer and its absence in the hypercapnic blue bloater have suggested the terms "fighter" and "nonfighter," reflecting possible underlying differences in ventilatory drive. Indeed, early studies indicated decreased ventilatory responsiveness to hypercapnia in patients with ...
The most common cause of airway obstruction in the anesthesia setting is iatrogenic, i.e. occurs with induction of general anesthesia/ sedation, when a reduced level of consciousness and loss of pharyngeal muscle tone leads to the back of the tongue falling backwards against the posterior pharyngeal wall in the patient positioned supine. Other conditions causing a reduced level of consciousness (intoxication, stroke, head injury, ...) can lead to airway obstruction for the same reason.. (Partial) upper airway obstruction due to the same mechanism can occur during sleep causing snoring and as a consequence of obstructive sleep apnea.. The potential types of obstacles to gas flow through the airway are blood, pus, secretions, edema and hematoma, either within the airway or external to the airway but compressing it, tumor or other tissue, a foreign body, regurgitated material or the vocal chords in cases of paralysis.. ...
The importance of SaO2 in the assessment of respiratory distress in bronchial asthma has been reported. Objectives: To evaluate the correlation between blood gas analysis and chest X-ray lung opacities in young children presenting with acute respiratory symptoms. Methods: Eighty patients (43 males and 37 females aged 0.5-24 months; mean B SD 9.1 B 7.2 months), either with acute wheezing respiratory symptoms and/or with crackles were enrolled in our study. In all children, blood gas analysis and chest X-rays were performed within 12 h following admission to the emergency department. Results: In 55 children (68.75%) chest X-rays demonstrated lung opacities. Subjects with normal X-rays had paO2 and SaO2 higher than subjects with lung opacities (p ! 0.0001 and p = 0.0001, respectively). Children with lung opacities almost always presented paO2 !80 mm Hg. Sensitivity and specificity for the presence of lung opacities of paO2 !80 mm Hg were 81 and 90%, respectively, while sensitivity and specificity ...
Laryngeal cysts are cysts involving the larynx or more frequently supraglottic locations, such as epiglottis and vallecula. Usually they do not extend to the thyroid cartilage. They may be present congenitally or may develop eventually due to degenerative cause. They often interfere with phonation. Hoarseness is the most common presenting symptom, while pain, stridor or laryngeal obstruction are unusual complaints. They may cause significant respiratory obstruction leading to dyspnoea or respiratory distress and even cyanosis, and jugular and epigastric retractions. Congenital lesions may present with severe airway obstruction at birth calling for emergency intervention and intubation. There are three types of laryngeal cysts, namely, mucous, hemorrhagic and congenital. However, a new classification system for congenital laryngeal cysts on the basis of the extent of the cyst and the embryologic tissue of origin, is proposed for the ease of initial surgical management. Treatment can be medical or ...

Pneumoniae infection in adults with new-onset asthma imply that untreated chlamydial infections may have a part in the transition from the acute inflammation of bronchitis to the chronic inflammatory changes of asthma. Patients with acute bronchitis usually have a viral respiratory infection with ephemeral inflammatory changes that create sputum and symptoms of airway obstruction. Evidence of reversible airway obstruction when not infected Symptoms worse during the work but tend to improve during weekends, holidays and vacations Chronic cough with sputum production on a daily basis for a minimum of three months Upper airway inflammation and no signs of bronchial wheezing Evidence of infiltrate on the chest radiograph Evidence of increased interstitial or alveolar fluid on the chest radiograph Usually related to a precipitating event, such as smoke inhalation Signs of reversible airway obstruction even when not infected Symptoms worse during the work week but tend to improve during weekends, ...

Thermoplasty: A newly FDA-approved treatment for patients with moderately severe to severe asthma has met with initial success. This treatment targets reducing airway obstruction in asthma patients due to bronchial muscle hypertrophy. A cardinal feature of asthma is hypertrophy or thickening of the bronchial smooth muscle. At times, the bronchial smooth muscle wall is so thick that it results in persistent and severe narrowing of the bronchial passageway, thus limiting airflow. Patients not responding to conventional therapy who have persistent, severe airway obstruction might be candidates for this new form of treatment. Patients undergo bronchoscopy, in which heat is applied to the local bronchial smooth muscle, resulting in a shrinking or diminution in the bronchial smooth muscle mass, and thus, increasing the airway lumen diameter, resulting in decreased airway obstruction. This is a new technique which is invasive and associated with a potential for adverse events. ...

Background Airway calibers are related to changes in Fractional exhaled nitric oxide (FeNO) in asthma; however, this effect is not well understood especially during spontaneous airway obstruction.. Objective The aim of this study was to evaluate whether FeNO levels could be masked by airway obstruction in patients wit asthma and COPD.. Methods FeNO and spirometry measurements were performed before and after albuterol inhalation in 20 steroid-naive asthmatics with moderate to severe airway obstruction. For comparison, 15 normal subjects, 16 asthmatics using inhaled corticosteroids/ long-acting β(2)-adrenoceptor agonist(ICS/LABA combination) and another group of patients with COPD were also studied. All the patients with asthma and COPD recruited had positive bronchodilator test (BDT).. Results FeNO(median [25th-75th percentiles]) increased significantly after albuterol inhalation in steroid-naive asthmatics 61.50[40.50-85.00]vs.80.00[53.00-108.00], P=0.000) but not in treated asthmatics ...
Rationale: Asthma is a serious health problem with increasing prevalence in the world. It is a chronic disease which is characterized by episodes of reversible airway obstruction due to underlying chronic airway inflammation and airway hyperresponsiveness to different bronchial stimuli. Evidence indicates that reduced physical activity may be associated with the severity of asthma and the increasing asthma prevalence (Rusmussen F et al. ERJ). Several studies have shown that physical activity improves asthma control and the quality of life of asthma patients. However, physical training does not lead to improved lung function. Obesity, is another important factor that increases the risk of asthma and is related to the severity of asthma. Compared to normal, lean asthma patients, obese asthma patients have more missed school days per year, a lower peak flow, a higher need of inhalation medication and less often acceptable asthma control. The relationship with atopy, allergic rhinitis and bronchial ...
Lung cancer is the most common cause of cancer death in Australia, Europe and the USA. Up to 20-30% of these cancers eventually affect the central airways and result in reduced quality of life, dyspnoea, haemoptysis, post-obstructive pneumonia and ultimately death. Non-malignant processes may also lead to central airway obstruction and can have similar symptoms. With the development of newer technologies, the last 20 years have seen the emergence of the field of interventional pulmonology to deal specifically with the diagnosis and management of thoracic malignancy, including obstruction of the central airways. This review discusses the pathology, pre-procedure work-up and management options for obstructing central airway lesions. Several treatment modalities exist for dealing with endobronchial pathology with local availability and expertise guiding choice of treatment. While the literature lacks large, multicentre, randomized studies defining the optimal management strategy for a given ...

Axon regeneration after experimental spinal-cord damage (SCI) could be promoted by combinatorial remedies that raise the intrinsic development capacity from the damaged neurons and reduce environmental elements that inhibit axon development. we analyzed Rabbit polyclonal to JAKMIP1. the functional position of regenerated sensory afferents in the dorsal columns after SCI. Half a year post-injury, we located and electrically mapped useful sensory axons that got regenerated beyond the damage site. The regenerated axons got reduced conduction speed, decreased frequency-following capability, and increasing to repetitive stimuli latency. Lots of the axons that got regenerated in to the dorsal columns rostral towards the damage site had been chronically demyelinated. These outcomes demonstrate that regenerated sensory axons stay in a chronic pathophysiological condition and emphasize the necessity to restore regular conduction properties to regenerated axons after spinal-cord damage. the damage … In ...

Wheezes occupy different portions of the respiratory cycle depending on the site of airway obstruction and its nature. The fraction of the respiratory cycle during which a wheeze is produced roughly corresponds to the degree of airway obstruction.[2][3] Bronchiolar disease usually causes wheezing that occurs in the expiratory phase of respiration. As a rule, extrathoracic airway obstruction produce inspiratory sounds. Intrathoracic major airway obstruction produces inspiratory as well as expiratory sounds. Distal airway obstruction predominantly produces expiratory sounds.[4] The presence of expiratory phase wheezing signifies that the patients peak expiratory flow rate is less than 50% of normal.[5] Wheezing heard in the inspiratory phase, on the other hand, is often a sign of a stiff stenosis, usually caused by tumors, foreign bodies or scarring. This is especially true if the wheeze is monotonal, occurs throughout the inspiratory phase (i.e. is "holoinspiratory"), and is heard more ...
Inflammation of the small airways contributes to the severity of the disease and affects the quality of life of patients with asthma. However, the exact role and relevance of small airways disease in asthma is still unclear. This is partly due to the difficulty of measuring small airways pathology with a sensitive and specific parameter. The most commonly used variable as an indicator of small airway obstruction is the FEF50%. Currently, it is not known which clinical symptoms are associated with small airways disease and how a patient will perceive small airway abnormalities. This knowledge is important to assess small airways disease in patients with asthma and adjust therapy to improve quality of life.The primary purpose of this study is to develop a questionnaire for patients with asthma with and without small airways disease for general and specialist practice ...
165 trials were reviewed and eight were included; a total of 461 patients have been studied (229 with CBA; 232 with intermittent beta-agonists). Overall, admission to hospital was reduced with CBA compared to intermittent beta-agonists (RR: 0.68; 95% CI: 0.5 to 0.9); patients with severe airway obstruction at presentation appeared to benefit most from this intervention (RR: 0.64; 95% CI: 0.5 to 0.9). Patients receiving CBA demonstrated small but statistically significant improvements in pulmonary function tests when all studies were pooled. Patients receiving CBA had greater improvements in % predicted FEV-1 (SMD: 0.3; 95% CI: 0.03 to 0.5) and PEFR (SMD: 0.33; 95% CI: 0.1 to 0.5); this effect was observed by 2-3 hours. Continuous treatment was generally well tolerated, with no clinically important differences observed in pulse rate (WMD: -2.87; 95% CI: -6.0 to 0.3) or blood pressure (WMD: -1.75; 95% CI: -5.6 to 2.1) between the treatment groups. Tremor was equally common in both groups (OR: ...

Clinical asthma is characterized by reversible airway obstruction which is commonly due to an exaggerated airway narrowing referred to as airway hyperresponsiveness (AHR). Although debate exists on the complex etiology of AHR, it is clear that airway smooth muscle (ASM) mediated airway narrowing is a major contributor to airway dysfunction. More importantly, it is now appreciated that smooth muscle is far from being a simple cell with only contractile ability properties. Rather, it is more versatile with the capacity to exhibit numerous cellular functions as it adapts to the microenvironment to which it is exposed. The emerging ability of individual smooth muscle cells to undergo changes in their phenotype (phenotype plasticity) and function (functional plasticity) in response to physiological and pathological cues is an important and active area of research. This article provides a brief review of the current knowledge and emerging concepts in the field of ASM phenotype and function both under ...
