*  Acute airway obstruction due to postoperative retropharyngeal hematoma after anterior cervical fusion: a retrospective analysis...
Although dyspnea after ACF is not common, it is a severe complication that can develop into hypoxemia and be fatal without appropriate treatment. There are a few reports concerning development of hematoma after anterior cervical surgery. Some authors have considered that vessel damage and intramuscular bleeding due to excessive traction during surgery are the main causes of the hematoma [6-8]. Incorrect hemostasis of the vessels, including the vertebral artery, thyroid artery, and veins of the neck, has been reported as one of the causes of postoperative hematoma in these patients. Further, there are reports of dyspnea being caused by delayed bleeding associated with arterial aneurysms and venous thrombosis [7, 9]. In this study, we could not find the injured vessel during the second surgery, except in one case of injury to the jugular vein. We did not identify any specific risk factor for development of postoperative hematoma, possibly because of our small number of cases. However, we did find ...
*  Welcome to CDC stacks | Airway Obstruction Among Latino Poultry Processing Workers in North Carolina - 32700 | CDC Public Access
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 ...

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 ...
*  Assessing airway patency | Anesthesia Airway Management (AAM)
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, ...
*  Laryngeal cyst - Wikipedia
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 ...

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 ...

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 ...

*  Managing obstruction of the central airways
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, ...
*  Development of Small Airway Disease Questionnaire - Tabular View - ClinicalTrials.gov
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 ...
*  Burns in Small Animals - WSAVA2013 - VIN
Is the equivalent to third-degree burn; affects the epidermis, dermis, and subcutaneous tissue. Generally patients are presented in shock status, the skin looks dry and bloodless, the hair coat can be easily epilated just pulling, and there is no pain sensation. Large scar remains after a prolonged and slow healing process. Mortality is common.. Some protocols also use the term "burns with bone involvement" to refer to the human 4th-degree burns, but there is no consensus about that term.. Burns as Emergency: General Approach. I Stage Care: From Arriving to 36 Hours. The initial assessment should start with the general physical condition, systemic compromise, amount of body and surface affected, plus degree of local injury. If the loss of skin is large enough, euthanasia can be recommended.. Animals affected by smoke inhalation should be placed on 100% oxygen early after they arrive to ICU. Inhalation of hot air and heat may lead to upper airway obstruction due to the ...
*  Airway smooth muscle in asthma: Phenotype plasticity and function | ScholarBank@NUS
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 ...
