A rationalisation of the 1350 boxes used throughout the book gives a simpler and clearer presentation of the various categories. [books.google.com]

• Cough

  The hemorrhagic lesions appeared to be induced by coughing due to bronchitis for which the penicillin was given. [ncbi.nlm.nih.gov]

  A barking, seal-like cough, low fever and worse at night. Inhaled foreign body: Common, especially in children aged 1 to 2 years. Preceded by choking or coughing. Tracheitis: Uncommon cause. Usually occurs under the age of 3 years. [patient.info]

  […] experience the following symptoms: Shortness of breath Chest and/or throat tightness Feeling they are "breathing through a straw" Stridor/wheezing Difficulty with inhalation and/or exhalation Frequent throat clearing Intermittent hoarseness Chronic cough [nationaljewish.org]

  Assessment A harsh, barking cough in a febrile, miserable, but otherwise well child suggests Croup. Absent cough with low pitched expiratory stridor (often snoring) and drooling suggests epiglottitis. [rch.org.au]

• Dyspnea

  But slight inspiratory dyspnea and stridor may occur during crying or on exertion 5 Laryngeal obstruction classification: Ⅱ°slight inspiratory dyspnea during quiet respiration, and exaggeration on exertion. [slideplayer.com]

  Exercise-induced laryngeal obstruction is a cause of exercise-induced dyspnea. [healio.com]

  KEYWORDS: Athlete; dyspnea; exercise; larynx; swimming [ncbi.nlm.nih.gov]

• Hoarseness

  A boy with junctional epidermolysis bullosa died from acute laryngeal obstruction at the age of 29 months, having been hoarse since early infancy. [ncbi.nlm.nih.gov]

  Although their usual presenting symptom is hoarseness, acute airway obstruction from laryngeal polyps is uncommon. [academic.oup.com]

  […] with VCD and EILO may experience the following symptoms: Shortness of breath Chest and/or throat tightness Feeling they are "breathing through a straw" Stridor/wheezing Difficulty with inhalation and/or exhalation Frequent throat clearing Intermittent hoarseness [nationaljewish.org]

• Laryngeal Disease

  Abstract The aim of this study was to find out if laryngeal obstruction could be assessed by measuring the glottic area using computed tomography (CT). Results from model studies were compared with those from twelve patients with laryngeal diseases. [ncbi.nlm.nih.gov]

• Gagging

  Cannot be used in awake patients, as it causes them to gag and potentially vomit. [learnpicu.com]

  There may also be paroxysmal coughing, gagging or choking, hoarseness, wheezing, tachycardia and other signs of respiratory distress. Patients are usually anxious and distressed. Narrowing above the larynx causes stridor. [patient.info]

  […] relieved within 2-5 minutes of the onset partial UAO: stable, or progressive deterioration signs and symptoms may be mild but as they worsen include coughing, inspiratory stridor, crowing or noisy respiration, dysphonia, aphonia, choking, drooling and gagging [aic.cuhk.edu.hk]

RESULTS: Of 88 athletes who completed a full workup, 31 (35.2%) had EILO and 38 (43.2%) had a positive bronchoprovocation or bronchodilator reversibility test. [ncbi.nlm.nih.gov]

Finally circulatory collapse may occur or may die of asphyxia or cardiac failure. 8 Laryngeal obstruction Treatment Ⅰ°：etiological treatment, antibiotics and corticosteroid. 9 Laryngeal obstruction Treatment Ⅱ°：etiological treatment. in case of tumors [slideplayer.com]

The patients reported a better ability to breathe while exercising, after surgical treatment, as revealed by VAS scores. [bora.uib.no]

In case of severe supraglottic collapse and pronounced symptoms during strenuous exertion, surgical treatment (supraglottoplasty) has been suggested. [ncbi.nlm.nih.gov]

Treatment General approach There are currently no published randomised controlled treatment trials. [erj.ersjournals.com]

Overall prognosis is considered considered generally poor 6. tracheal atresia Promoted articles (advertising) [radiopaedia.org]

PMID: 29631737 Prognosis Solomon NP, Pham A, Gallena S, Johnson AT, Vossoughi J, Faroqi-Shah Y J Voice 2022 Sep;36(5):734.e1-734.e6. Epub 2020 Sep 26 doi: 10.1016/j.jvoice.2020.09.002. [ncbi.nlm.nih.gov]

The prognosis is poor with squamous cell carcinoma of the trachea, which carries a 5-year survival of approximately 40% when resectable and 7% when unresectable. [clinicaladvisor.com]

[…] especially when being prepared for children Consume food slowly and fully chew food before swallowing, which is an effective preventative method Closely watch very young children while they play with toys and small play items (toy parts) What is the Prognosis [dovemed.com]

Prognosis of EILO It has been suggested that laryngeal growth and maturation during puberty should make the larynx more robust to inward forces at high minute ventilation [ 61 ]. [link.springer.com]

Finally circulatory collapse may occur or may die of asphyxia or cardiac failure. 8 Laryngeal obstruction Treatment Ⅰ°：etiological treatment, antibiotics and corticosteroid. 9 Laryngeal obstruction Treatment Ⅱ°：etiological treatment. in case of tumors [slideplayer.com]

CONCLUSIONS: In athletes with unexplained respiratory symptoms, EILO is an important differential diagnosis not discerned from other etiologies by clinical features. [ncbi.nlm.nih.gov]

This review of the literature provides an overview of the current understanding of the definition, epidemiology, diagnosis and management of EILO. [ncbi.nlm.nih.gov]

Epidemiology The reported epidemiology of ILO varies considerably, depending on the diagnostic criteria employed ( table 2 ). [erj.ersjournals.com]

Biphasic stridor suggests subglottic or glottic obstruction. [ 1 ] Epidemiology The detailed epidemiology of stridor depends on the cause, but it is worth noting the following patterns of disease: Stridor is common in younger children with smaller airways [patient.info]

Specifically, our understanding of the aetiology and pathophysiology remain poor and despite considerable technological advances, robust, validated, diagnostic and treatment algorithms are yet to be established. [erj.ersjournals.com]

See Figure 2 for a comparison of what 1 mm of circumferential edema does in terms of airway resistance to an infant and an adult Pathophysiology Upper airway obstruction can occur for a variety of causes, but fundamentally, leads to increased airway resistance [learnpicu.com]

Gavin Joynt Pathophysiology - obstruction is likely to occur at sites of anatomic narrowing such as the hypopharynx at the base of the tongue and the false and true vocal cords at the laryngeal opening. - sites of airway obstruction are referred to as [aic.cuhk.edu.hk]

Palliative interventions for patients with chronic upper airway obstruction include: balloon dilatation airway stenting laser therapy electrocautery and argon plasma coagulation cryotherapy nocturnal, noninvasive, positive-pressure ventilation Pathophysiology [clinicaladvisor.com]

The primary physician must know when and where to send these children in order to prevent the fatalities so frequent in previous years. [ncbi.nlm.nih.gov]

Airway secretions, edema, and downward folding of the epiglottis cause complete laryngeal obstruction, preventing endotracheal intubation. [anatomicaljustice.com]

Prompt evaluation and management of suspected UAO may prevent subsequent complications including cardiac arrest, anoxic brain injury, and negative pressure pulmonary edema. [accessmedicine.mhmedical.com]

There are no definitive methods to prevent Acute Upper Airway Obstruction. However, proper precautions may be taken to reduce risks. [dovemed.com]

The American Thoracic Society and the European Respiratory Society define refractory asthma as asthma that requires treatment with high-dose inhaled corticosteroids (ICS) plus a second controller and/or systemic corticosteroids to prevent it from becoming [figshare.com]
