Exposure to nitrogen dioxide and the occurrence of bronchial obstruction in children below 2 years. (1/1199)

BACKGROUND: The objective of the investigation was to test the hypothesis that exposure to nitrogen dioxide (NO2) has a causal influence on the occurrence of bronchial obstruction in children below 2 years of age. METHODS: A nested case-control study with 153 one-to-one matched pairs was conducted within a cohort of 3754 children born in Oslo in 1992/93. Cases were children who developed > or = 2 episodes of bronchial obstruction or one episode lasting >4 weeks. Controls were matched for date of birth. Exposure measurements were performed in the same 14-day period within matched pairs. The NO2 exposure was measured with personal samplers carried close to each child and by stationary samplers outdoors and indoors. RESULTS: Few children (4.6%) were exposed to levels of NO2 > or = 30 microg/m3 (average concentration during a 14-day period). In the 153 matched pairs, the mean level of NO2 was 15.65 microg/m3 (+/-0.60, SE) among cases and 15.37 (+/-0.54) among controls (paired t = 0.38, P = 0.71). CONCLUSIONS: The results suggest that NO2 exposure at levels observed in this study has no detectable effect on the risk of developing bronchial obstruction in children below 2 years of age.  (+info)

Comparison of two new methods for the measurement of lung volumes with two standard methods. (2/1199)

BACKGROUND: The two most commonly used methods for the measurement of lung volumes are helium dilution and body plethysmography. Two methods have been developed which are both easier and less time consuming to perform. Mathematical modelling uses complex calculations from the flow-volume loop to derive total lung capacity (TLC), and the nitrogen balance technique uses nitrogen from the atmosphere to calculate lung volume in a similar way to helium dilution. This study was designed to compare the two new methods with the two standard methods. METHODS: Sixty one subjects were studied, 23 with normal lung function, 17 with restrictive airway disease, and 21 with obstructive ventilatory defects. Each subject underwent repeated measurements of TLC by each of the four methods in random order. Reproducible values were obtained for each method according to BTS/ARTP guidelines. Bland-Altman plots were constructed for comparisons between the methods and paired t tests were used to assess differences in means. RESULTS: Bland-Altman plots showed that the differences between body plethysmography and helium dilution fell into clinically acceptable ranges (agreement limits +/-0.9 l). The agreement between mathematical modelling or the nitrogen balance technique and helium dilution or body plethysmography was poor (+/-1.8-3.4 l), especially for subjects with airflow obstruction. CONCLUSIONS: Neither of the new methods agrees sufficiently with standard methods to be useful in a clinical setting.  (+info)

Respiratory mechanics in airways obstruction associated with inspiratory dyspnoea. (3/1199)

Inspiratory muscle strength and the flow and elastic pressure opposing inspiration were measured in seven patients with severe airways obstruction who found inspiration difficult at rest. A comparison was made of measurements obtained from seven normal subjects and five patients with airways obstruction not experiencing inspiratory dyspnoea at rest. Measurements were also obtained when inspiratory dyspnoea was induced in the normal subjects by adding an inspiratory resistance or by voluntarily increasing lung volume. Compared with the controls the inspiratory muscle strength of the patients was reduced but was not significantly less than that of the patients without inspiratory dyspnoea. The pressure required to produce inspiratory flow was significantly greater when inspiratory dyspnoea was present (P = 0-01). However, there was considerable overlap in the pressures of those with and without inspiratory dyspnoea. A better relationship was obtained when muscle strength was considered. The ratio of inspiratory muscle strength to the pressure required to produce flow was 0-24 +/- 0-07 (mean +/- SD) in patient with inspiratory dyspnoea, 0-10 +/- 0-03 in patients without inspiratory dyspnoea, and 0-033 +/- 0-019 in normal subjects. There was no overlap between the two patient groups. The ratios of the normal subjects were increased when inspiratory dyspnoea was induced and, with the exception of two cases, were all above those obtained when inspiratory dyspnoea was absent. Inspiratory dyspnoea was experienced with lower ratios in the normals than in the patients with airways obstruction.  (+info)

Aspects of serum and sputum antibody in chronic airways obstruction. (4/1199)

Immunoglobulin levels and precipitating antibody against a range of microbial antigens were measured in simultaneously collected serum and sputum samples from patients with chronic bronchitis (11), cystic fibrosis (9), bronchiectasis (9), and asthma (4). Sputum was prepared by dialysis and high-speed centrifugation methods. Results showed that it was possible to detect precipitating antibody in the sputum, and the rate was increased when both methods were used. A discrepancy was noted between the detection rate in the sputum and serum. This, combined with the lack of correlation between sputum and serum immunoglobulins, lack of relationship between bronchial inflammation and sputum immunoglobulins, and the lack of IgM in the sputum suggested that the antibody and immunoglobulin were locally produced. Sputum IgA (7S) in patients with chronic bronchitis was significantly lower (P less than 0-05) than that found in patients with cystic fibrosis and bronchiectasis. Significant differences (P less than 0-05) were also noted in serum IgG levels between patients with chronic bronchitis, bronchiectasis, and cystic fibrosis while serum IgM levels in patients with chronic bronchitis were significantly lower (P less than 0-05) when compared to serum levels in patients with cystic fibrosis. The presence of precipitating antibody in the sputum raises the possibility that type III reactions may be important in the pathogenesis of these conditions.  (+info)

A resuscitated case from asphyxia by large bronchial cast. (7/1199)

A 62-year-old woman with bronchiectasis suffered from asphyxia due to a large bronchial cast that obstructed the bronchial tree. Immediate bronchoscopic suction of a bronchial cast of 17 cm in length through the intubated tube relieved the patients without any complications. Large bronchial casts appear to be rare in this century but it should be considered in patients with acute exacerbation of excessive sputa not only in patients with asthma or allergy but also in patients with respiratory tract infection.  (+info)

Clinical studies of styrene workers: initial findings. (8/1199)

Styrene monomer is a high volume chemical used chiefly in production of polystyrene. A clinical survey of 493 production workers was undertaken at the oldest and largest monomer production, polymerization, and extrusion facility in the U.S. Relative exposure durations and levels were obtained from occupational histories. Significant differences between the high and low exposure groups were found with regard to history of acute prenarcotic symptoms, acute lower respiratory symptoms, prevalence of FEV 1/FV less than 75 per cent, and elevated GCTP. Other liver function tests, chest x-ray, FVC less than 80 per cent, and hematological parameters showed no distinct pattern. A concomitant mortality study has been mounted and is in progress.  (+info)

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 ...
Response hypoxia (Part 9)Response hypoxia (Part 9)
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 ...
Assessing airway patency | Anesthesia Airway Management (AAM)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, 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 cyst - WikipediaLaryngeal 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 initial surgical management. Treatment can be medical or ...

Upper airways obstruction - Oxford MedicineUpper airways obstruction - Oxford Medicine
At resting levels of ventilation, the main airway can be reduced to a diameter of 3 mm or so before respiratory distress and stridor occur. Little more narrowing is required to precipitate complete asphyxia, hence when upper airways obstruction is suspected, assessment of severity, diagnosis, and treatment is a medical emergency....

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 ...

Managing obstruction of the central airwaysManaging 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, multicentre, randomized studies defining the optimal management strategy for a given ...

Pneumoniae infection in adults with new-onset asthma indicate that untreated chlamydial infections may have a part in the transition from the intense 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 produce sputum and symptoms of airway obstruction. Signs of airway obstruction that is reversible when not infected Symptoms worse during the work week but tend to improve during vacations, holidays and weekends Persistent cough with sputum production on a daily basis for a minimum of three months Upper airway inflammation and no evidence of bronchial wheezing Evidence of infiltrate on the chest radiograph Signs of increased interstitial or alveolar fluid on the chest radiograph Typically 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 ...
Wheeze - WikipediaWheeze - Wikipedia
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 ...

Prader-Willi Syndrome (PWS) in Children: There have been reports of fatalities after initiating therapy with somatropin in pediatric patients with PWS who had one or more of the following risk factors: severe obesity, history of upper airway obstruction or sleep apnea, or unidentified respiratory infection. Male patients with one or more of these factors may be at greater risk than females. Patients with PWS should be evaluated for signs of upper airway obstruction and sleep apnea before initiation of treatment with somatropin. If during treatment with somatropin, patients show signs of upper airway obstruction (including onset of or increased snoring) and/or new onset sleep apnea, treatment should be interrupted. All patients with PWS treated with somatropin should also have effective weight control and be monitored for signs of respiratory infection, which should be diagnosed as early as possible and treated aggressively ...

Obstructive sleep apnea (OSA) is characterized by recurrent upper airway obstructions during sleep. The most common animal model of OSA is based on subjecting rodents to intermittent hypoxic exposures and does not mimic important OSA features, such as recurrent hypercapnia and increased inspiratory efforts. To circumvent some of these issues, a novel murine model involving non-invasive application of recurrent airway obstructions was developed. An electronically controlled airbag system is placed in front of the mouses snout, whereby inflating the airbag leads to obstructed breathing and spontaneous breathing occurs with the airbag deflated. The device was tested on 29 anesthetized mice by measuring inspiratory effort and arterial oxygen saturation (SaO(2)). Application of recurrent obstructive apneas (6s each, 120/h) for 6h resulted in SaO(2) oscillations to values reaching 84.4 +/- 2.5% nadir, with swings mimicking OSA patients. This novel system, capable of applying controlled recurrent ...
Development of Small Airway Disease Questionnaire - Tabular View - ClinicalTrials.govDevelopment 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 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.

Airway smooth muscle in asthma: Phenotype plasticity and function | ScholarBank@NUSAirway smooth muscle in asthma: Phenotype plasticity and function | [email protected]
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 ...
