Inflammatory Pseudotumor of the Central Airways A Case Report and Literature Review

Journal of Bronchology. 14(4):255-260, October 2007

Endobronchial inflammatory pseudotumor (EIP) is an uncommon, benign entity in the central airways, frequently causing acute respiratory insufficiency by occluding the trachea or main-stem bronchi. Surgical resection of the tumor is a treatment option; however, it is associated with high morbidity. We recently encountered the case of a 24-year-old woman with EIP in the central airways that was successfully treated with nonsurgical multimodality approach using a combination of steroid therapy, radiotherapy, and repetitive bronchoscopic electrocauterizations.

Creation of an Interventional Bronchoscopy Technical Plateau at Cho Ray Hospital Ho Chi Minh City Vietnam A World Bronchology Foundation Project

Journal of Bronchology. 14(4):289-292, October 2007

Cho Ray Hospital is one of 3 large hospitals in Ho Chi Minh City (formerly known as Saigon), Vietnam. Despite limited resources and equipment, more than 3000 flexible bronchoscopies are performed there each year, usually for diagnosis of infection, lung cancer, and airway stenosis. Members of the World Bronchology Foundation (Philanthropic arm of the World Bronchology Foundation) went on-site to deliver a rigid bronchoscope and accessories (Bryan Corp, Woburn, MA). Hands-on training of 2 experienced flexible bronchoscopists occurred daily for 5 days, to achieve proficiency in rigid bronchoscopic resection, dilation, and electrocautery, as well as to recognize indications, contraindications, and patient safety measures pertaining to interventional procedures in patients with central airway obstruction.

A Case of Resected Huge Goiter With the Temporal Placement of a Dumon Stent

Journal of Bronchology. 14(4):286-288, October 2007

An 86-year-old woman with a 30-year history of goiter was hospitalized with severe stridor and progressive dyspnea on exertion that had worsened over the past year. The trachea was severely compressed by a huge mass, measuring 15 cm in diameter, on the left side of her neck. For the prevention of postoperative instability, a Dumon stent was placed in the trachea for 3 days.

Efficacy and Safety of Dexmedetomidine During Bronchoscopy in Patients With Moderate to Severe COPD or Emphysema

Journal of Bronchology. 14(4):233-236, October 2007

Dexmedetomidine (Precedex) is a sedative with a profile which is very appealing for short procedures, but its use in bronchoscopy has not yet been studied. This pilot study examines the efficacy and safety of dexmedetomidine during bronchoscopy in patients with pulmonary compromise. Patients were prospectively enrolled. Dexmedetomidine was administered before and during the procedure.

Measuring functional performance in patients with COPD a discussion of patient-reported outcome measures

rent Medical Research and Opinion, Volume 23, Number 11, November 2007 , pp. 2655-2665(11)

Chronic obstructive pulmonary disease (COPD) is a chronic condition and a major public health concern. Moreover, its prevalence is increasing. COPD commonly affects patient performance of daily activities that people perform in order to meet basic needs, fulfill usual roles, and maintain their health and well-being. What types of activities are affected and to what degree? How do these effects change over time? What impact, positive or negative, do various treatments have on the capacity of patients to perform activities? To address these questions, the concept of activity performance must be defined and appropriately measured.

A Technique to Intubate a Single Lung Using Combined Endotracheal Tubes When a Standard Endotracheal Tube is Inadequate

Journal of Bronchology. 14(4):261-263, October 2007

Massive hemoptysis is a life-threatening emergency encountered by bronchoscopists. Oftentimes stabilizing these patients requires use of selective lung intubation. We present 2 cases of massive hemoptysis secondary to malignancies. Both cases required an extralong endotracheal tube to accomplish selective lung isolation. We used a unique technique of constructing an extralong endotracheal tube from 2 regular endotracheal tubes at the bedside.

Bronchial Pigmentation as a Manifestation of Amiodarone Pulmonary Toxicity

Journal of Bronchology. 14(4):275-277, October 2007

Numerous well-recognized manifestations of amiodarone pulmonary toxicity have been described since the advent of this medication for the treatment of cardiac arrhythmias. The typical presentation is a subacute infiltrative lung illness with bilateral infiltrates that develops within several years of treatment onset. We describe a previously unrecognized complication of long-term amiodarone use, characterized by cough and black airway pigmentation that resolved with discontinuation of amiodarone.

Assessment of B-type natriuretic peptide in patients with pneumonia

International Journal of Clinical Practice

doi:10.1111/j.1742-1241.2007.01305.x

The mammalian heart synthesises and secretes B-type natriuretic peptide (BNP), which has potent diuretic, natriuretic and vascular smooth muscle-relaxing effects as well as complex interactions with the hormonal and nervous systems. Recent studies described that BNP was acute phase reactant. In this study, we aimed to evaluate BNP levels in patients with pneumonia.

Barriers to Metered-dose Inhaler spacer Use in Canadian Pediatric Emergency Departments A National Survey

Acad Emerg Med Volume 14, Issue11 1106-1113

Metered-dose inhalers and spacers (MDI+S) are at least as effective as nebulizers for treating children with mild to moderate asthma exacerbations. Despite advantages in terms of efficacy, side effects, and ease of use, MDI+S are not used in many North American pediatric emergency departments (PEDs).

Atopy and new-onset asthma in young Danish farmers and CD14 TLR2 and TLR4 genetic polymorphisms: a nested case-control study

Clinical & Experimental Allergy, Volume 37, Number 11, November 2007 , pp. 1602-1608(7)

Evidence exists that exposure to high levels of microbial agents such as endotoxin in the farm environment decreases the risk of atopic sensitization. Genetic variation in innate immunity genes may modulate the response to microbial agents and thus influence susceptibility to asthma and atopy.


10/30/2007 03:26 PM

Association between genetic variations in prostaglandin E2 receptor subtype EP3 gene Ptger3 and asthma in the Korean population

Clinical & Experimental Allergy, Volume 37, Number 11, November 2007 , pp. 1609-1615(7)

Recent investigations suggest that prostaglandin E2 (PGE2) is important in the pathogenesis of not only aspirin-intolerant asthma but also asthma unrelated to aspirin intolerance.

Surviving streptococcal toxic shock syndrome a case report

Journal of Medical Case Reports 2007, 1:118

Streptococcal toxic shock syndrome and associated myositis caused by group A beta-hemolytic streptococcus pyogenes generally have a poor outcome despite aggressive operative treatment. Frequently the diagnosis is missed initially as the clinical features are non-specific. The progression to a toxic state is rapid and unless definitive treatment measures are initiated early, the end result can be catastrophic.

Neutrophil and monocyte receptor expression in uncomplicated and complicated influenza A infection with pneumonia

Scandinavian Journal of Infectious Diseases 04 October 2007

Following influenza, the elderly and those with chronic heart/lung diseases are often affected by bacterial complications such as pneumonia. Whether neutrophil and monocyte functions are affected differently in patients with or without complications is less well known. Therefore, blood neutrophil and monocyte surface receptor expressions were measured in patients with influenza A, with or without complications, by means of flow cytometry.

Elevated levels of high mobility group box chromosomal protein-1 HMGB-1 in sera from patients with severe bacterial pneumonia coinfected with influenza virus

Scandinavian Journal of Infectious Diseases 04 October 2007

Plasma levels of high mobility group box chromosomal protein-1 (HMGB-1), as well as of other inflammatory molecules such as interleukin-6 (IL-6), regulated on activation normal T-cell expressed and secreted (RANTES), and soluble intercellular adhesion molecule-1 (sICAM-1), were determined in patients with bacterial pneumonia coinfected with influenza virus. HMGB-1 levels were significantly elevated in these patients compared to patients undergoing mild bacterial pneumonia alone (p<0.01).

Fire-eating Hazards of hydrocarbon aspiration

Australasian Radiology, Volume 51, Number 6, December 2007 , pp. 567-569(3)

A 30-year-old male fire eater presented following aspiration of hydrocarbon fuel during a performance. A plain chest radiograph carried out 2-h after aspiration showed left lower lobe consolidation. The patient subsequently developed worsening shortness of breath, haemoptysis, fever and myalgia and a repeat plain chest radiograph showed extensive bilateral pulmonary consolidation with mediastinal and bilateral hilar lymphadenopathy. Computed tomography showed features consistent with necrotizing pneumonia.

Catathrenia nocturnal groaning an abnormal respiratory pattern during sleep

European Journal of Neurology, Volume 14, Number 11, November 2007 , pp. 1236-1243(8)

Catathrenia (nocturnal groaning) is a rare condition characterized by monotonous irregular groans occurring during sleep. Groaning was associated with disproportionate prolonged expiration causing reduced breathing rate without oxygen desaturation. The breathing pattern with prolonged expiration and sound production alternated with a normal respiratory pattern without groaning. Endoesophageal pressure during groaning showed mildly positive swings at the initial phase of expiration suggesting a partial mild expiratory upper airway obstruction. At the end of the follow-up period, all patients reported persistent nocturnal groaning but no other clinical manifestations.

An iatrogenic complication of closed tube thoracostomy for penetrating chest trauma

Journal of the New Zealand Medical Association, 26-October-2007, Vol 120 No 1264

Penetrating thoracic trauma poses a management challenge to the on-call surgeon. A casual and unwary approach can lead to unforeseen complications in the initial height of management of such patients. We present a case of penetrating thoracic trauma where initial management with closed tube thoracostomy resulted in intubation of the stomach that had herniated into the chest through a diaphragmatic rent. Patients with penetrating injuries to the zone between the abdomen and chest should be managed with a high index of suspicion.

Symptom Assessment of Patients With Chronic Obstructive Pulmonary Disease

Western Journal of Nursing Research, Vol. 29, No. 7, 845-863 (2007)

The primary purpose of this secondary data analysis was to evaluate the efficacy and suitability of the Memorial Symptom Assessment Scale (MSAS) for use with patients with severe chronic obstructive pulmonary disease (COPD). Symptoms experienced by patients with severe COPD were assessed in the original investigation using the 32-item MSAS.

Frequency of pertussis in children with prolongued cough

Scandinavian Journal of Infectious Diseases 11 October 2007

To determine the frequency of pertussis in children 16 y who had prolonged cough (14 d), a prospective study was conducted at an outpatient clinic of a paediatric hospital. Nasopharyngeal swabs were taken for culture and nucleic acid testing by polymerase chain reaction (PCR) for Bordetella pertussis. Immunoglobulin A and immunoglobulin G antibodies against pertussis toxin (PT) were tested by ELISA in paired serum samples. A total of 148 patients were recruited during 1 y. Pertussis was detected in 25 (16.9%) patients with at least 1 of the tests. PCR was positive in 12 patients, and 9 cases was diagnosed serologically.

Treatment characteristics in elderly asthmatics

International Journal of Clinical Practice doi:10.1111/j.1742-1241.2007.01272.x

In this study, we evaluated the effect of ageing on treatment response by comparing two groups of patients with asthma. All asthmatic patients in the study were assessed on repeated occasions once admitted to the hospital: soon after admission (0 h), and then at 5th, 10th, 24th, 48th, 72nd hour, 7th day and in stable period. We compared two groups of patients: younger asthmatics, which had 33 younger aged <60, and elderly asthmatics, comprised of 29 elderly aged -60 years.

Role of TNF-alpha in lung tight junction alteration in mouse model of acute lung inflammation

Respiratory Research 2007, 8:75

In the present study, we used tumor necrosis factor-R1 knock out mice (TNF-alphaR1KO) to understand the roles of TNF-alpha on epithelial function in models of carrageenan-induced acute lung inflammation. In order to elucidate whether the observed anti-inflammatory status is related to the inhibition of TNF-alpha, we also investigated the effect of etanercept, a TNF-alpha soluble receptor construct, on lung TJ function.

Simian virus 40 vectors for pulmonary gene therapy

Respiratory Research 2007, 8:74

Sepsis remains the leading cause of death in critically ill patients. One of the primary organs affected by sepsis is the lung, presenting as the Acute Respiratory Distress Syndrome (ARDS). Organ damage in sepsis involves an alteration in gene expression, making gene transfer a potential therapeutic modality. This work examines the feasibility of applying simian virus 40 (SV40) vectors for pulmonary gene therapy.

Challenges in pulmonary fibrosis - 5 The NSIP UIP debate

Thorax 2007;62:1008-1012

Among the idiopathic interstitial pneumonias, the two entities-idiopathic pulmonary fibrosis (IPF) characterised by the presence of the usual interstitial pneumonia pattern of histopathology (IPF/UIP) and non-specific interstitial pneumonia (NSIP; same nomenclature for the histopathological pattern and idiopathic disease)-have provoked considerable debate.

The value of multiple tests of respiratory muscle strength

Thorax 2007;62:975-980

Respiratory muscle weakness is an important clinical problem. Tests of varying complexity and invasiveness are available to assess respiratory muscle strength. The relative precision of different tests in the detection of weakness is less clear, as is the value of multiple tests.


10/30/2007 02:37 PM

Simple modification of CURB-65 better identifies patients including the elderly with severe CAP

We read with interest the article by Barlow et al. The CURB-65 criteria currently recommended by the British Thoracic Society (BTS) based on the study by Lim et al are useful and more pragmatic than other criteria, as shown in their study.

Impairment of the swallowing reflex in exacerbations of COPD

Thorax 2007;62:1017; doi:10.1136/thx.2007.084715

An exacerbation of chronic obstructive pulmonary disease (COPD) has a serious impact on disease progression and is associated with high medical costs, but the cause of about one-third of exacerbations cannot be identified. Adequate protective reflexes in the airways play an important role in the prevention of aspiration of bacteria-containing oropharyngeal or gastric secretions. Impairment of these reflexes, such as the swallowing reflex, therefore represents a potential risk factor for exacerbations of COPD. We have conducted a cross-sectional survey to evaluate the prevalence of impairment of the swallowing reflex in patients with COPD and to determine whether this is a risk factor for COPD exacerbations.

Clinical investigation of an outbreak of alveolitis and asthma in a car engine manufacturing plant

Thorax 2007;62:981-990

Exposure to metal working fluid (MWF) has been associated with outbreaks of extrinsic allergic alveolitis (EAA) in the USA, with bacterial contamination of MWF being a possible cause, but is uncommon in the UK. Twelve workers developed EAA in a car engine manufacturing plant in the UK, presenting clinically between December 2003 and May 2004. This paper reports the subsequent epidemiological investigation of the whole workforce.


10/30/2007 02:34 PM

Reducing inflammation in COPD the evidence builds

Thorax 2007;62:927-928

It has been accepted for more than 20 years that asthma is an inflammatory disease of the airways, but it is more recent that airways inflammation has been accepted to be important in chronic obstructive pulmonary disease (COPD).


10/30/2007 02:33 PM

Muscle fibre type shifting in the vastus lateralis of patients with COPD is associated with disease severity a systematic review and meta-analysis

Thorax 2007;62:944-949

Skeletal muscle dysfunction is a common feature in chronic obstructive pulmonary disease (COPD) which is associated with intrinsic muscular abnormalities. One of the most consistently reported alterations is a shift from fibre type I to II in the vastus lateralis of these patients. Surprisingly, the relationship between this shift and the severity and phenotype of COPD remains unclear. A study was conducted to determine whether vastus lateralis muscle fibre type proportions are associated with COPD disease severity and to provide reference values for the proportions of fibre types in the vastus lateralis in COPD.


10/30/2007 02:32 PM

Effects of rehabilitative exercise on peripheral muscle TNFalpha IL-6 IGF-I and MyoD expression in patients with COPD

Thorax 2007;62:950-956

Skeletal muscle wasting commonly occurs in patients with chronic obstructive pulmonary disease (COPD) and has been associated with the presence of systemic inflammation. This study investigated whether rehabilitative exercise training decreases the levels of systemic or local muscle inflammation or reverses the abnormalities associated with muscle deconditioning.


10/30/2007 02:31 PM

Effect of salmeterol fluticasone propionate on airway inflammation in COPD a randomised controlled trial

Thorax 2007;62:938-943

Airway inflammation in chronic obstructive pulmonary disease (COPD) is characterised by infiltration of CD8+ T cells and CD68+ macrophages and an increased number of neutrophils, whereas few studies have described the presence of eosinophils. Although the anti-inflammatory effects of corticosteroids in stable COPD are unclear, recent studies suggest that combination therapy could be beneficial. A study was therefore undertaken to evaluate combined salmeterol/fluticasone propionate (SFC) and fluticasone propionate (FP) alone on inflammatory cells in the airways of patients with COPD.


10/30/2007 02:30 PM

Characterisation of phenotypes based on severity of emphysema in chronic obstructive pulmonary disease

Thorax 2007;62:932-937

Airflow limitation in chronic obstructive pulmonary disease (COPD) is caused by a mixture of small airway disease and emphysema, the relative contributions of which may vary among patients. Phenotypes of COPD classified purely based on severity of emphysema are not well defined and may be different from the classic phenotypes of "pink puffers" and "blue bloaters".


10/30/2007 02:29 PM

Relationship between air pollution, lung function and asthma in adolescents

Thorax 2007;62:957-963

The interrelationships between air pollution, lung function and the incidence of childhood asthma have yet to be established. A study was undertaken to determine whether lung function is associated with new onset asthma and whether this relationship varies by exposure to ambient air pollutants.

Traumatic pulmonary pseuodocysts two case reports

Traumatic pulmonary pseudocyst (TPP) is a rare complication, sometimes encountered after blunt thoracic trauma and even more rarely following penetrating injuries. It is more common among pediatric and young adult patients. Although TPP is usually benign in nature, complications associated with hemoptysis and secondary infection may develop. The treatment is conservative. In this report, we present two rare cases of TPP occuring after a high-speed accident and a stab wound injury, where conservative treatment provided good outcomes.

Pulmonary embolism An Unusual Cause Of Acute Liver Failure

The Internet Journal of Emergency and Intensive Care Medicine. 2007. Volume 10 Number 2

Pulmonary embolism is still a challenging diagnosis and a very high index of suspicion is required. Symptoms and signs of acute right heart failure are still non-specific and often vary according to the precipitating condition. In this particular case, evolving liver failure and severe coagulation disorder as the initial presentation made the management of this patient very challenging and several causes of sudden decompensated liver failure were ruled out. Acute reduction of splanchnic flow was considered but in the context of relative good oxygenation and no history or clinical signs of deep venous thrombosis, the diagnosis of pulmonary embolism was not considered as a primary cause of liver failure and evolving multiple organ failure.

Cloning of the canine RNA polymerase I promoter and establishment of reverse genetics for influenza A and B in MDCK cells

Virology Journal 2007, 4:102

Recent incidents where highly pathogenic influenza A H5N1 viruses have spread from avian species into humans have prompted the development of cell-based production of influenza vaccines as an alternative to or replacement of current egg-based production. Madin-Darby canine kidney (MDCK) cells are the primary cell-substrate candidate for influenza virus production but an efficient system for the direct rescue of influenza virus from cloned influenza cDNAs in MDCK cells did not exist.

An Asthmatic Adolescent With a Rash and Eosinophilia

Pediatric Emergency Care. 23(10):727-730, October 2007

Children frequently visit emergency departments with asthma exacerbations. Many of these asthmatic children may have fever and/or pneumonia, but when associated with eosinophilia or evidence of vasculitis, other diagnoses should be considered. Churg-Strauss syndrome is a rare form of systemic vasculitis, which usually occurs in patients with asthma in association with eosinophilia. The diagnosis of Churg-Strauss syndrome can be difficult because this syndrome may arise at first as a common association between asthma and allergic rhinitis. A delay in diagnosis and treatment may increase the morbidity from the complications of vasculitis. We report a young asthmatic adolescent who presented with vasculitis, eosinophilia, and peripheral neuropathy.

Computed tomography characteristics of primary pulmonary lymphoepithelioma-like carcinoma

British Journal of Radiology (2007) 80, 803-806

Primary pulmonary lymphoepithelioma-like carcinoma is a very rare subtype of lung cancer. This report documents the CT features of 16 Chinese patients diagnosed with primary pulmonary lymphoepithelioma-like carcinoma from January 1999 to December 2005. A pre-treatment CT was used to assess the tumour site, size, borders, pleural and vascular involvement, and the presence of lymph node involvement. The majority of the patients were female non-smokers with centrally located tumours. Lymph node involvement and bronchial and vascular encasement were frequent. In an Epstein-Barr virus endemic area, primary pulmonary lymphoepithelioma-like carcinoma is an important differential diagnosis to consider.

Spread of the Streptococcus pneumoniae Taiwan19F-14 clone among children in Greece

Clinical Microbiology and Infection doi:10.1111/j.1469-0691.2007.01837.x

Serotype 19F pneumococci were a leading cause of infections among children in Athens, Greece during 2001–2006. In total, 143 19F isolates were typed by pulsed-field gel electrophoresis (PFGE), and 38 isolates representing the main PFGE types were also characterised by multilocus sequence typing. A diversity of distinct strains belonging to sequence types 236, 1035, 274, 172 and 319 were identified, but multidrug-resistant isolates related to the Taiwan19F-14 clone (ST236) constituted 76.9% of the isolates. Spread of the Taiwan19F-14 clone explains, in part, the high incidence of antibiotic resistance observed among pneumococci reported recently from Athens.

Pollen proteolytic enzymes degrade tight junctions

Respirology doi:10.1111/j.1440-1843.2007.01175.x

Asthma and allergic rhinitis are significant, increasing causes of morbidity worldwide. Pollen, a major cause of seasonal rhinitis/conjunctivitis, carries proteolytic enzymes on its surface. We showed previously that peptidase allergens from house dust mites compromise epithelial barrier function by degrading the extracellular domains of the tight junction proteins, occludin and claudin, thus facilitating allergen delivery across epithelial layers. In this study, we aimed to determine whether peptidases from allergenic pollens should similarly be considered to have a role in disrupting tight junctions.

Fiber Deposition in the Tracheobronchial Region Experimental Measurements

Inhalation Toxicology, Volume 19, Issue 13 October 2007 , pages 1071 - 1078

Fiber deposition efficiency in the tracheobronchial region was studied by using two human airway replicas. Carbon fibers with a monodisperse diameter of 3.66 were delivered into lung casts at the flow rates of 15, 45, and 60 L/min. Deposition efficiencies in each airway bifurcation were obtained individually. Even though the data shows large variability among the bifurcations within the same generation, there is a general trend for the data obtained in these two replicas. Our results show that fiber deposition for carbon fibers increases with the Stokes number, indicating that inertial impaction is the dominant mechanism.

Sialic acid receptor detection in the human respiratory tract evidence for widespread distribution of potential binding sites for human and avian influenza viruses

Respiratory Research 2007, 8:73

Influenza virus binds to cell receptors via sialic acid (SA) linked glycoproteins. They recognize SA on host cells through their haemagglutinins (H). The distribution of SA on cell surfaces is one determinant of host tropism and understanding its expression on human cells and tissues is important for understanding influenza pathogenesis. The objective of this study therefore was to optimize the detection of alpha2,3 -linked and alpha2,6-linked SA by lectin histochemistry by investigating the binding of Sambucus nigra agglutinin (SNA) for SAalpha2,6Gal and Maackia amurensis agglutinin (MAA) for SAalpha2,3Gal in the respiratory tract of normal adults and children.

Adult Cystic Fibrosis

JAMA. 2007;298:1787-1793

Cystic fibrosis is a multisystem disease characterized primarily by chronic pulmonary infection and bronchiectasis, pancreatic exocrine impairment, and elevated sweat chloride. In the last 4 decades, new treatment strategies and aggressive nutritional management have resulted in a significant increase in expected survival, with median predicted survival in cystic fibrosis now to older than 35 years. This increase in predicted survival has also been aided by a greater appreciation of the potential variability in the presentation and severity of cystic fibrosis, resulting in identification of a growing number of mild cases. As it is estimated that within the next decade more than half of all individuals with cystic fibrosis will be aged 18 years or older, adult medicine caregivers are increasingly likely to encounter patients with cystic fibrosis and be exposed to their unique medical management.

Hypoxia divergently regulates production of reactive oxygen species in human pulmonary and coronary artery smooth muscle cells

Am J Physiol Lung Cell Mol Physiol 293: L952-L959, 2007. First published August 10, 2007

Acute hypoxia causes pulmonary vasoconstriction and coronary vasodilation. The divergent effects of hypoxia on pulmonary and coronary vascular smooth muscle cells suggest that the mechanisms involved in oxygen sensing and downstream effectors are different in these two types of cells. Since production of reactive oxygen species (ROS) is regulated by oxygen tension, ROS have been hypothesized to be a signaling mechanism in hypoxia-induced pulmonary vasoconstriction and vascular remodeling. Furthermore, an increased ROS production is also implicated in arteriosclerosis.

As a result the speciality has led in the development of surgical models that illustrate the biomechanical regulation of lung growth. Using transgenic mutants, biologists have similarly discovered much about the biochemical regulation of prenatal lung growth. Airway smooth muscle (ASM) and its prenatal contractility airway peristalsis (AP) represent a novel link between these areas: ASM progenitors produce an essential biochemical factor for lung morphogenesis, whilst calcium-driven biomechanical ASM activity appears to regulate the same.
