A 59-year-old man presented to the emergency department with a chief complaint of sore throat after swallowing sodium picosulfate/magnesium citrate powder for bowel preparation, without first dissolving it in water. The initial evaluation showed significant mucosal injury involving the oral cavity, pharynx, and epiglottis. Endotracheal intubation was performed for airway protection in the emergency department, because the mucosal swelling resulted in upper airway compromise. After conservative treatment in the intensive care unit, he underwent tracheostomy because stenosis of the supraglottic and subglottic areas was not relieved...

Management of anesthesia for a child with an upper airway foreign body is fraught with particular challenges. We present the case of a 3-year-old girl who presented to the emergency department with a 12-cm sewing needle protruding from her mouth and unknown vascular involvement. We were faced with establishing a secure airway despite exclusion of mask ventilation or use of a laryngeal mask airway. Moreover, peripheral intravenous access was lost before adequate sedation. Ultimately, we were able to safely induce anesthesia and achieve endotracheal intubation...

OUTCOME OBJECTIVE: For over fifty years, otolaryngologists, allergists, and immunologists have debated the effect of adenoidectomy or adenotonsillectomy on asthma outcomes in children. Although some have suggested that adenotonsillectomy may contribute to the subsequent development of asthma in children, others have argued that a common mechanism may cause both upper and lower airway disease, and that children who have symptoms severe enough to warrant adenotonsillectomy are also at increased risk of asthma and atopic disease...

BACKGROUND: Pertussis or whooping cough is an acute respiratory illness caused by the Gram-negative pathogen Bordetella pertussis. Despite high vaccination coverage whooping cough is currently re-emerging in many developed countries. Although the causes of pertussis resurgence are matter of debate, emerging evidences suggest that acellular vaccines efficiently protect against the hallmark symptoms of pertussis disease but fail to prevent colonization. This presumably impacts on increased risk of bacterial transmission and consequent spread throughout the population...

We report a 64-year-old man who suffered from recurrent visible swelling attacks since the age of 20 as well as episodes with severe upper airway edema, resulting in 4 emergency tracheotomies. Eventually after 44 years he was diagnosed with hereditary angioedema (HAE) type II. The aims of this report is to emphasize the importance of awareness concerning HAE, which does not respond to traditional anti-allergic therapy, and remind physicians to test for functional C1-INH deficiency.

BACKGROUND: In developing countries with limited access to ENT services, performing emergency cricothyroidotomy in patients with upper airway obstruction may be a life-saving last resort. An established Danish-Zimbabwean collaboration of otorhinolaryngologists enrolled Zimbabwean doctors into a video-guided simulation training programme on emergency cricothyroidotomy. This paper presents the positive effect of this training, illustrated by two case reports. CASE REPORTS: A 56-year-old female presented with upper airway obstruction due to a rapidly progressing infectious swelling of the head and neck progressing to cardiac arrest...

INTRODUCTION: Cricothyroidotomy is an emergency procedure that can be used to secure the airway in situations in which intubation and ventilation are not possible. PRESENTATION OF CASE: We describe a case of 79-year-old male presenting with facial trauma combined with massive upper airway bleeding and swelling in which cricothyroidotomy was required to open the airway in an elderly male patient taking antiplatelet agents who suffered a simple ground-level fall. DISCUSSION: Although emergency airway management is often required in patients with Le Fort fractures, mandibular condyle fractures exhibit a significant relationship with ground-level falls, which are not usually associated with emergency airway management...

Paradoxical vocal fold motion disorder, also commonly termed vocal cord dysfunction, is a poorly understood cause of acute upper airway obstruction. Patients with paradoxical vocal fold motion frequently present to the emergency department (ED) with acute respiratory distress and stridor. Lack of familiarity with this disorder may lead to delayed diagnosis or misdiagnosis and unnecessary intubations or surgical airway procedures. Although long-term management of paradoxical vocal fold motion is well described, there is a paucity of information about acute evaluation and management...

INTRODUCTION: Massive bleeding from the thyroid gland causing airway compromise secondary to indirect neck trauma is rare. PRESENTATION OF CASE: An 89-year-old woman was transferred to our emergency department due to anterior neck pain after a traffic accident. She had been propelled forward and struck her head on the front mirror during emergency braking. Airway patency was confirmed at the first contact. Although her vital signs were stable at presentation, she gradually suffered from respiratory distress and severe dyspnea, implying airway compression, therefore requiring endotracheal intubation...

Cricothyroidotomy is a surgical procedure involving penetration through the skin and cricothyroid membrane to maintain airway patency during life-threatening emergency conditions. Complications such as bleeding and laryngeal stenosis can result from it. Our aim in this study was to identify the anatomical structures located on the membrane and to ascertain whether there is a safe area on the membrane for this procedure. Thirty larynx specimens fixed with 10% formaldehyde in the Department of Anatomy were dissected...

What is the topic of this review? This article presents emerging evidence for heightened carotid body chemoreflex activity as a major driver of sympathetic activation and hypertension in sleep apnoea patients. What advances does it heighlight? This article discusses the recent advances on cellular, molecular and epigenetic mechanisms underlying the exaggerated chemoreflex in experimental models of sleep apnoea. The carotid bodies are the principal peripheral chemoreceptors for detecting changes in arterial blood oxygen concentration, and the resulting chemoreflex is a potent regulator of the sympathetic tone, blood pressure and breathing...

Taste receptors are well known for their role in communicating information from the tongue to the brain about nutritional value or potential toxicity of ingested substances. More recently, it has been shown that taste receptors are expressed in other locations throughout the body, including the airway, gastrointestinal tract, brain and pancreas. The roles of some 'extraoral' taste receptors are largely unknown, but emerging research suggests that bitter and sweet taste receptors in the airway are capable of sensing bacteria and modulating innate immunity...

BACKGROUND: Cough is symptomatic of a broad range of acute and chronic pediatric respiratory illnesses. No studies in children have tested for an extended panel of upper airway respiratory viruses and bacteria to identify whether they predict cough outcomes, irrespective of clinical diagnosis at the time of acute respiratory illness (ARI). We therefore determined whether upper airway microbes independently predicted hospitalization and persistent cough 28-days later in children presenting with an ARI, including cough as a symptom...

Negative pressure pulmonary edema is a potentially life-threatening condition that may occur when a large negative intrathoracic pressure is generated against a 'physically' obstructed upper airway during emergence from anesthesia. We report a 35 year old male patient who is morbidly obese and undergoing laparoscopic gastric bypass who developed negative pressure pulmonary edema without any evidence of a 'physical' upper airway obstruction. In our patient, the negative pressure pulmonary edema occurred after complete reversal of neuromuscular blockade and during manual positive pressure ventilation with the endotracheal tube still in place and in the presence of an oral airway...

INTRODUCTION: Congenital airway obstruction is of varied etiology and uncommonly encountered. Prenatal care and imaging have enhanced detection of these abnormalities and allow for multi-disciplinary care planning for airway management at delivery. Despite the availability and advances in prenatal imaging, unanticipated airway obstruction may not be identified until the time of delivery. METHODS: Case series. RESULTS: Four airway emergencies were encountered in the labor and delivery suite over an eight-month period...

A rare case of lethal idiopathic plasmacytic lymphadenopathy (IPL) with polyclonal hyperimmunoglobulinemia with chronic renal failure is described. A 40-year-old woman who had suffered from upper airways disease was admitted to the Emergency Room with acute renal failure and hypergammaglobulinemia. She developed pericardial effusion, a pruritic rash, splenomegaly and fell into a coma after 6 days. Multiple myeloma, infection, collagenopathy, and coagulopathy were ruled out. Finally, a form of malignant hypergammapathy was suspected...

INTRODUCTION: Upper airway angioedema is a life-threatening emergency department (ED) presentation with increasing incidence. Angiotensin-converting enzyme inhibitor induced angioedema (AAE) is a non-mast cell mediated etiology of angioedema. Accurate diagnosis by clinical examination can optimize patient management and reduce morbidity from inappropriate treatment with epinephrine. The aim of this study is to describe the incidence of angioedema subtypes and the management of AAE. We evaluate the appropriateness of treatments and highlight preventable iatrogenic morbidity...

The growing popularity of novel psychoactive substances (NPS) has aroused the concerns of public health specialists. The pyrovalerone derivatives are a branch of synthetic cathinones, a very popular group of psychostimulant NPS. Despite numerous case reports of fatal intoxications, little is known about the cytotoxicity of these substances. Therefore, this study was aimed to evaluate the toxic properties of pyrovalerone, its highly prevalent derivative 3,4-methylenedioxypyrovalerone (3,4-MDPV) with its two major metabolites (catechol-MDPV and methylcatechol-MDPV) and the structural isomer 2,3-MDPV, together with newer members of the group, i...

The main challenge for surgical resection of tumors located at the upper trachea is contemplate formulated plan for providing maximal surgical access to the trachea while ensuring patent airway and adequate oxygenation at the same time. In this report, we describe a patient who presented with an upper tracheal tumor located 3cm from the vocal cord and severe tracheal constriction, occluding tracheal lumen by 90%. Initial ventilation was established by implantation with a supreme laryngeal mask airway. An emergent tracheotomy and distal tracheal intubation were used to combat bleeding and subsequent airway obstruction...
