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 (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 ...

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 ...

Background. This study sets out to estimate the prevalence and the degree of severity of bronchial obstruction in an adult population with three different diagnostic criteria: the European Respiratory Society (ERS), the American Thoracic Society (ATS), and the World Health Organization (WHO) defined as Global Obstructive Lung Disease (GOLD). Methods. 1514 subjects underwent complete medical evaluation and spirometry. Results. The prevalence of bronchial obstruction was respectively 27.5% (ERS), 33% (GOLD), and 47.3% (ATS). The prevalence of bronchial obstruction in the smoker group was 33.4% (ERS), 38.1% (GOLD), and 52.3% (ATS). The prevalence of obstruction in the ex-smoker group was 33% (ERS), 41.4% (GOLD), and 57.1% (ATS). The prevalence of obstruction in the non-smoker group was 21.1% (ERS), 24.9% (GOLD), and 38.6% (ATS). Conclusions. The results show that the prevalence of airway obstruction increases proportionally with age; the cigarette smoking represents an important conditioning ...

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 ...

This series highlights the potential for late presentation of upper airway obstruction in the Pierre Robin sequence. Of 10 patients with upper airway obstruction, seven (70%) presented between days 24 and 51. All infants had been seen by an experienced neonatologist or general paediatrician, and were not thought to have clinically significant upper airway obstruction. These results suggest that either significant upper airway obstruction is not being detected clinically by experienced neonatal or paediatric staff, or that obstruction is developing gradually in these infants.. While most reported series of infants with Pierre Robin sequence have not specifically stated the age at presentation of airway obstruction, the classical view has been that, if present, airway obstruction will be apparent from birth. This view is supported by the series of Benjamin and Walker.7 In this series 24 of 26 patients with Pierre Robin sequence had symptoms of obstruction apparent before 12 hours of age. The ...

AU - Johnson, A. M.. AU - Kron, I. L.. PY - 1989/1/1. Y1 - 1989/1/1. N2 - Bronchiolitis obliterans (irreversible small airway obstruction) is a late complication of heart-lung transplantation. Chronic immune rejection is believed to be the major cause of this complication. Our hypothesis was that denervation might contribute to airway obstruction. To test this hypothesis in the absence of immune rejection, we performed a lobectomy of the upper lobe of the left lung and autologous reimplantation of the lower lobe of the left lung in 13 growing pigs. To serve as age-matched controls, six other pigs had sham left thoracotomy and nine others had a lobectomy of the upper lobe of the left lung alone. Nine to 10 weeks after operation, the animals were anesthetized and the lungs mechanically ventilated. The lobes ...

Background: Upper airway compromise due to tracheobronchial stenosis commonly occurs in patients with Wegeners granulomatosis (WG). There is at present no consensus on the optimal management of this life threatening condition. Objective: To assess the results of laryngo-tracheobronchoscopy, intralesional steroid therapy, laser surgery and dilatation in managing obstructive tracheobronchial WG. Methods: Records of 18 previously untreated stridulous patients with obstructive tracheobronchial WG, treated between 2004 and 2006, were prospectively recorded on an airway database and retrospectively reviewed. Information about patient and lesion characteristics and treatment details were recorded. Treatment progress was illustrated using a timeline plot, and intervention-free intervals were calculated with actuarial analysis. Results: There were nine males and the average age at presentation was 40 (16) years (range 13-74). There were 13 patients with tracheal and five with tracheal and bronchial ...

Laryngeal cancer is relatively uncommon, encompassing around 1% of all cancers. Of these, squamous cell carcinoma accounts for the majority, with a high male:female perponderance (5:1)1. Chondrosarcoma accounts for around one percent2. It usually presents with classic signs and symptoms of a laryngeal tumour; ie dysphonia, inspiratory stridor, dysphagia, odynophagia, neck mass, or persistent cough3. It is usually a slow growing tumour and therefore rarely presents with acute airway obstruction. It is most commonly centred on the cricoid cartilage (70 - 75%), however it can also arise from the thyroid cartilage, epiglottis and arytenoids in descending order of incidence4.. Symptoms depend on the location. Subglottic and endolaryngeal tumours will generally cause dyspnoea. Extralaryngeal tumours may compress the oesophagus resulting in dysphagia5. In our case the patient presented with inspiratory stridor and mild dysphonia, due to its location originating outside of the larynx, ultimately ...

Congenital high airway obstruction syndrome (CHAOS) is a prenatally diagnosed clinical syndrome manifested by the presence of extremely large echogenic lungs, flattened or inverted diaphragms, a dilated tracheobronchial tree, ascites, and other manifestations of nonimmune hydrops due to complete obstruction of the fetal airway (Hedrick et al., 1994). No fetus diagnosed prenatally with CHAOS associated with hydrops and complete airway obstruction has survived without intervention. The exception to this occurs when there is spontaneous perforation of the laryngeal or tracheal atresia, which may occur in up to one-third of cases and results in resolution of the hydrops. ...

Nasal airway obstruction, a well-known cause of patient discomfort, is one of the most common presenting complaints to the otolaryngologist. The different causes of nasal airway obstruction are very wide-ranging, spanning from congenital life threatening causes to acquired benign causes. Herein, we present a case of nasal obstruction caused by widening of the posterior septum. A 52-year-old gentleman presented to the rhinology clinic with complaint of chronic nasal congestion for 4 years. Trials of topical steroid sprays and nasal saline rinses had been unsuccessful in symptoma- tic resolution. On anterior rhinoscopy, the septum was noted to be straight anteriorly, but appeared to be deviated bilaterally, flaring into the nasopharynx and obstructing the airway. A CT scan was performed, which showed soft tissue enlargement on the posterior aspect of the septum. The patient was subsequently taken to the operating room for a posterior septectomy and inferior turbinectomy. He reported alleviation of

Airway obstruction caused by pharyngolaryngeal swelling after intraoral removal of a submandibular gland stone Satomi Sugiyama, Toshinori Iwai, Nobuhide Ohashi, Senri Oguri, Makoto Hirota, Kenji Mitsudo Department of Oral and Maxillofacial Surgery/Orthodontics, Yokohama City University Hospital, Yokohama, Japan Abstract: Intraoral removal of a submandibular gland stone is less invasive than submandibulectomy, with no life-threatening airway complications reported until now. We report a case involving airway obstruction caused by pharyngolaryngeal swelling after intraoral removal of a submandibular gland stone. A 31-year-old man with a left submandibular gland stone underwent intraoral removal of the stone under general anesthesia and was discharged 1 day after surgery. That night, he was transported back to our hospital by ambulance for dyspnea. Because computed tomography showed pharyngolaryngeal swelling, he was intubated and managed by a ventilator. Four days later, the pharyngolaryngeal swelling

Studies were made on 56 10-11-year-old asthmatic children with onset of symptoms before 3 years of age, frequent and persistent attacks, and objective evidence of their disease with barrel chest deformity and/or reduction of the FEV 0·5/VC ratio to 50% or less, by clinical, physiological, and radiological techniques in an interval phase between their attacks.. There was a significant correlation between barrel chest deformity and (a) elevation of lung volumes (FRC, RV, TLC, FRC/TLC, and RV/TLC), and (b) reduction of the FEV1·0/VC ratio, indicating chronic hyperinflation and airways obstruction in the interval phase between attacks.. Radiological evidence of hyperinflation also correlated significantly with barrel chest deformity, increased lung volumes, and airways obstruction. These parameters were found to be important criteria for assessing chronicity in asthma.. The group showed evidence of growth retardation particularly for weight and to a lesser extent for height, these changes being ...

Upper airway obstruction (UAO) is an unpredictable and frequently occurring complication during induction of general anesthesia. Since obese patients ( BMI,30 km/ m2) are more vulnerable to develop airway obstruction either during sleep or under anesthesia, and the segment of obese individuals in the entire population keep growing, difficult airway management under anesthesia becomes even more challenging than ever. The most serious event related to difficult airway management under anesthesia is cannot intubate, cannot ventilate. Unfortunately, even with modern technologic advances, 16% of death and permanent brain damage related to anesthesia have been attributed to failure of difficult airway management 3. The American Society of Anesthesiologist (ASA) closed claim analysis of anesthesia complications indicate that a difficult airway is one of the most challenging scenarios continuously facing anesthesia providers. Indeed, it can be a fatal complication of general anesthesia. Therefore, ...

Gustducin is a guanosine nucleotide-binding proteins functionally coupled with taste receptors and thus originally identified in taste cells of the tongue. tongue sections with the same rabbit gustducin antibody. Whereas bad staining was confirmed in the tongue, rigorous materials were constantly stained in the brain. Moreover, immunostaining having a goat gustducin antibody could not demonstrate the materials in the brain tissue. The present study indicates a cross immunoreaction that occurs with the rabbit gustducin antibody in mouse mind samples, suggesting that the conventional bad settings may not be adequate when an immunostaining pattern is to be verified. Keywords: taste bud, immunohistochemistry, peptide neutralization, axonal terminal, polyclonal antibody Intro The guanosine nucleotide-binding protein, gustducin (McLaughlin et al. 1992), was originally recognized in taste cells of the tongue (Wong et al. 1996; Wong et al. 1999), and offers consequently been functionally coupled with ...

Purpose: Asthma is associated with reversible airway obstruction, leucocyte infiltration, airways hyperresponsiveness (AHR) and airways remodelling. Fluid accumulation causes pulmonary oedema contributing to airways obstruction. We examined the temporal relationship between the late asthmatic response (LAR) following allergen challenge of sensitised guinea-pigs and pulmonary oedema measured by magnetic resonance imaging (MRI). Materials and Methods: Ovalbumin (OVA) sensitised guinea-pigs received either a single OVA inhalation (acute) or nine OVA inhalations at 48 h intervals (chronic). Airways obstruction was measured as specific airways conductance (sGaw) by whole body plethysmography. AHR to inhaled histamine and bronchoalveolar lavage for leucocyte counts were measured 24 h after a single or the final chronic ovalbumin challenges. MRI was performed at intervals after OVA challenge and high intensity oedemic signals quantified. Results: Ovalbumin caused early bronchoconstriction, followed at ...

Pneumoniae infection in adults with new-onset asthma suggest 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 passing inflammatory changes that create symptoms and sputum of airway obstruction. Signs of airway obstruction that is reversible when not infected Symptoms worse during the work but have a tendency to improve during vacations, holidays and weekends Chronic cough with sputum production on a daily basis for a minimum of three months Upper airway inflammation and no signs of bronchial wheezing Signs of infiltrate on the chest radiograph Signs of increased interstitial or alveolar fluid on the chest radiograph Usually related to a precipitating event, such as smoke inhalation Evidence of reversible airway obstruction even when not infected Symptoms worse during the work week but tend to improve during ...

Background Foreign body aspiration can result in a spectrum of presentations, from minimal symptoms, often unobserved, to respiratory compromise, failure, and even death. This article is not intended to distinguish in detail acute airway obstruction from foreign body aspiration; for these patients, emergency life-saving interventions are nee...

Discussion:. The smaller lumen of the airway makes it more susceptible to severe obstruction. Any triggering factor that induces laryngeal spasm can cause complete respiratory obstruction resulting in rapidly fatal outcome. Accidental inhalation and ingestion of a foreign body has been reported in the literature,4 but a fragment of denture hanging between the two cords is quite unusual. The signs and symptoms due to foreign body aspiration can be described in three stages. The patient presents with a history of a choking episode, along with paroxysms of gagging and coughing. There may be no difficulty in breathing or there may be an acute respiratory obstruction demanding immediate attention. Once the patient gets over with this phase, the second stage continues as an asymptomatic interval. If still not managed, then the third stage characterized by symptoms of complications sets in which is due to long-standing foreign body retention. These are related to either delayed diagnosis or missed ...

Background Differences in asthma severity may be related to inflammation in the airways. The lower airway microbiota has been associated with clinical features such as airway obstruction, symptom control, and response to corticosteroids. Objective To assess the relationship between local airway inflammation, severity of disease, and the lower airway microbiota in atopic asthmatics. Methods A cohort of young adult, atopic asthmatics with intermittent or mild/moderate persistent symptoms (n = 13) were assessed via bronchoscopy, lavage, and spirometry. These individuals were compared to age matched non-asthmatic controls (n = 6) and to themselves after six weeks of treatment with fluticasone propionate (FP). Inflammation of the airways was assessed via a cytokine and chemokine panel. Lower airway microbiota composition was determined by metagenomic shotgun sequencing. Results Unsupervised clustering of cytokines and chemokines prior to treatment with FP identified two asthmatic phenotypes (AP),

The upper airway evolved anatomically in humans to subserve several important functions including swallowing, breathing, and vocalization.1 The multifunctionality of the upper airway increases the risk of certain diseases (e.g., aspiration and sleep apnea).2 These functions require that different segments of the airway have differing properties. The trachea receives some support by the tracheal rings, the nasal airway is surrounded by rigid structures, and the oral airway has a rigid boney roof, the hard palate. On the other hand, the pharyngeal airway does not have rigid structures supporting it. It is a collapsible tube whose patency is maintained by muscles whose function is affected by arousal state (sleep/wake, and more specifically during sleep, the stage of sleep), the structures around it, and posture. Thus, the pharyngeal airway is divided anatomically and physiologically into the nasopharynx, retropalatal oropharynx, retroglossal oropharynx, and hypopharynx. ...

Certain tests may also be used to determine the cause of your airway obstruction. During an emergency, your doctor will likely order an X-ray first to determine the cause of your symptoms. If an X-ray fails to determine the cause of the obstruction, your doctor may choose to order more advanced testing. This may include a bronchoscopy. During this procedure, your doctor inserts an instrument called a bronchoscope through your mouth or nose to look into your lungs for any foreign bodies. Bronchoscopy can also help your doctor evaluate different causes of obstruction. This includes tracheomalacia, or weakness and collapse of the trachea. It also includes infectious causes, such as mucous plugging in patients with chronic lung conditions like emphysema and cystic fibrosis. Your doctor may also order a laryngoscopy. During this procedure, your doctor will examine your larynx with an instrument called a laryngoscope. Additional tests may include a CT scan of the head, neck, or chest to determine ...

In most cases this does not cause any problems, but in a small number of infants it can cause serious problems in the first few months of life. This is mostly due to the tongue moving back into the throat when the child breathes in, blocking the airway. This is known as upper airway obstruction, and can cause serious disruption to breathing and feeding. If your child has an upper airway obstruction, they will need to stay in hospital for a period of time so their breathing can be monitored and assessed. During this time, non-surgical methods of improving the airway obstruction will be tried, such as the insertion of a nasopharyngeal (nay-zo-far-an-jeel) tube (a tube down the nose that improves air flow to the breathing tubes and lungs).. In a very small number of cases, these non-surgical methods are not successful and a childs breathing problems become life threatening. In other instances, the non-surgical methods may be required for a very long time, and this can be very difficult to sustain. ...

We observed an oscillatory flow while ventilating critically ill patients with the Dräger Oxylog 3000™ transport ventilator during interhospital transfer. The phenomenon occurred in paediatric patients or in adult patients with severe airway obstruction ventilated in the pressure-regulated or pressure-controlled mode. As this had not been described previously, we conducted a bench study to investigate the phenomenon. An Oxylog 3000™ intensive care unit ventilator and a Dräger Medical Evita-4 NeoFlow™ intensive care unit ventilator were connected to a Dräger Medical LS800™ lung simulator. Data were registered by a Datex-S5™ Monitor with a D-fend™ flow and pressure sensor, and were analysed with a laptop using S5-Collect™ software. Clinical conditions were simulated using various ventilatory modes, using various ventilator settings, using different filters and endotracheal tubes, and by changing the resistance and compliance. Data were recorded for 258 combinations of patient factors and

This is the eighth of a series of articles on how to practise yoga, in consultation with Ayurvedic and Yoga Consultant Dr Pushpika Attanayake. This week the discussion continues from last week on benefits of yoga practice for asthma patients.. According to Dr Attanayake, the episodes of severe airway obstruction associated with asthma are caused by bronchial spasms. Panic at the time of the attack aggravates this situation. This situation could be averted if the patient is trained to remain calm and relaxed. As a consequence, the bronchial spasm would be reduced or released.. These yoga techniques use suggestive relaxation and helps relax the thoracic muscles, face and muscles of cervical region. It brings results through slow movements, yoga asana and Pranayama. Yoga breathing is known to be stamina-building. It also contributes to deep relaxation of different groups of muscles, lowering breath rate, calming the mind, bringing emotional well- being and a lifestyle of internal awareness and ...

In line with previous findings in the literature, we showed that occupational exposure to VGDF was clearly associated with lower levels of FEV1 and FEV1/FVC as well as with a higher prevalence of airway obstruction in both our general populations investigated.8-11 ,17 ,18 Associations in our study were exposure dependent. In the European Community Respiratory Health Survey (ECRHS) study, high exposure to VGDF was associated with a 61 mL lower FEV1 in current smokers, whereas in our study we found a 96 mL lower FEV1 associated with high exposure to VGDF in ever smokers. Contrary to our findings, there was no association in never smokers from the ECRHS study.18 These differences might relate to the lower average age of the ECRHS population, which consisted mainly of young adults (range 20-44 years) compared with LifeLines (18-89 years). We found consistent associations with the subcategory gases and fumes in both cohorts. The association between exposure to mineral dust, lower level of FEV1 and ...

Asthma (from ásthma panting) is the common chronic inflammatory disease of the airways characterized by variable and recurring symptoms, reversible airflow obstruction, and bronchospasm. Symptoms include wheezing, coughing, chest tightness, and shortness of breath. Asthma is clinically classified according to the frequency of symptoms, forced expiratory volume in 1 second, and peak expiratory flow rate. Asthma may also be classified as atopic or non-atopic. It is thought to be caused by a combination of genetic and environmental factors. Treatment of acute symptoms is usually with an inhaled short-acting beta-2 agonist. Symptoms can be prevented by avoiding triggers, such as allergens and irritants, and by inhaling corticosteroids. Leukotriene antagonists are less effective than corticosteroids and thus less preferred. Its diagnosis is usually made based on the pattern of symptoms and/or response to therapy over time. The prevalence of asthma has increased significantly since the 1970s. As of ...

TORRES-PALOMINO, Gregory; JUAREZ-DOMINGUEZ, Gabriela; GUERRERO-HERNANDEZ, Manuel y MENDEZ-SANCHEZ, Lucía. Airway obstruction due to cystic hygroma in a newborn. Bol. Med. Hosp. Infant. Mex. [online]. 2014, vol.71, n.4, pp.233-237. ISSN 1665-1146. http://dx.doi.org/10.1016/j.bmhimx.2014.07.001.. Background: Cystic hygroma is a diffuse dilatation of the lymphatic system, which can be prenatally diagnosed by ultrasound. The incidence is 1/6,000 live births and 1/750 spontaneous abortions. This malformation can occur at the cervical level located in the inferior lateral part of the neck where it appears with large single or multilocular cavities. It is generally caused by a lack of connection with jugular lymphatic channels or with the venous drainage system lymph sacs. Case report: In order to emphasize these diseases and non-surgical treatment options, we present a patient with a cervical cystic hygroma that compromises the airway and digestive tract due to tumor extension and treatment with pure ...

Dr Tim Chapman says: Asthma should, and can be well controlled to prevent flares of the condition. Flares of asthma are best managed sooner rather than later (and therefore reduce risk of needing oral steroid therapy or even hospital admission) with a long-term aim to prevent complications such as persistent airway obstruction (causing chronic breathlessness) or bronchiectasis (causing a chronic productive cough and increased risk of chest infections). Essentially good control allows a good quality of life with no or little limitation to what you can do. In order to achieve this a holistic approach to asthma management is needed. One aspect involves understanding if there is an allergic component to the asthma. Knowing this allows access to some newer therapies, as well as broadening the range of the tried and tested therapies that are available. This can be tested through simple skin prick testing to see what you are allergic to.. If there is no allergic component, there are still many ...

Allergen inhalation by atopic asthmatics in the laboratory results in most of the manifestations of asthma, including reversible airflow obstruction, AHR and airway inflammation. This methodology has been used to examine the mechanisms of eosinophil, T-cell, and dendritic cell trafficking to/from the bone marrow to/from the blood and to the airways. The current proposal will capitalize on the unique opportunity offered by this allergen-specific model of direct bronchial challenge, by using MHC class II allergen tetramer reagents to enrich and characterize, ex vivo, Fel d 1 epitope-specific T cells before and after a localized bronchial allergen challenge. The over arching hypothesis of this proposal is that trafficking of allergen-specific T cells (tetramer+) from the blood to the airways and bone marrow is associated with the development of the late asthmatic reaction. This study will measure the frequency of Fel d 1-specific T cells, how these cells traffic between relevant compartments ...
