x Prehospital pediatric airway management is difficult and controversial. Options include bag-mask ventilation (BMV), endotracheal tube (ETT), and laryngeal mask airway (LMA). Emergency Medical Services personnel report difficulty assessing adequacy of BMV during transport. Capnography, and capnograph tracings in particular, provide a measure of real-time ventilation currently used in prehospital medicine but have not been well studied in pediatric patients or with BMV. Our objective was to compare pediatric capnographs created with 3 airway modalities.

x Extracorporeal membrane oxygenation (ECMO) is an effective respiratory and circulatory support in patients in refractory cardiogenic shock or cardiac arrest. Peripheral ECMO sometimes requires left heart drainage; however, few reports state that pulmonary arterial (PA) venting is required during ECMO support. We present a case of a 14-year-old boy who required PA venting during ECMO support after resuscitation from near-drowning in freshwater. A biventricular assist device with an oxygenator implantation was intended on day 1; however, we were unable to proceed because of increasing of pulmonary vascular resistance from the acute lung injury.

x Diffuse idiopathic skeletal hyperostosis is an idiopathic disorder characterized by intervertebral bridges of ossification along the anterior and lateral aspects of the spine. This case report describes an 87-year-old man presenting with an acute onset of stridor. Computed tomography revealed a large osteophyte originating from the cervical spine requiring tracheostomy due to a critical narrowing of the laryngeal inlet. Diffuse idiopathic skeletal hyperostosis is a common cause of dysphagia but rarely results in critical airway obstruction.

x Status asthmaticus is both a common and dangerous cause of acute dyspnea in the emergency department (ED) setting. Although most cases respond favorably to standard treatment, there are rare cases in which therapy beyond traditional treatment is needed. One of these treatment modalities includes inhalational anesthesia. We present a case in which inhaled sevoflurane was initiated out of the ED for a life-threatening asthma exacerbation refractory to conventional treatment. To our knowledge, this is only the second case to report the use of inhaled anesthetics initiated out of the ED for status asthmaticus and is the first report of its kind to thoroughly detail the respiratory response noted while inhalation anesthesia was being implemented.

x Spontaneous pneumomediastinum (SPM) is defined as a non-traumatic air leak from alveolar, bronchial or esophageal rupture along vascular sheaths and tissue planes into the mediastinum due to increased pressure in the trachea, bronchi, alveoli or esophagus [1]. SPM is rare in children, with a bimodal incidence peaking in children less than 7 years of age and then again in adolescence [1]. Historically, the diagnosis of SPM is made with physical examination findings and chest radiography.

x Benign acute childhood myositis is a rare postviral myositis seen in school-aged children after a common upper respiratory infection (URI), most commonly caused by influenza [J Microbiol Immunol Infect 2004;37:95-98]. Predominantly seen in boys, this condition causes bilateral calf tenderness and pain with ambulation, often presenting as a refusal to bear weight. To avoid activation within the gastroc-soleus complex, the child will frequently compensate with a “Frankenstein gait,” described as a stiff-legged posture with shuffling gait [CMAJ 2009;181:711-713].

He was treated with unusually high-dose nitroglycerin (NTG) intravenously (IV; NTG ≈ 70 mg for 1 hour). To suppress dyspnea, systolic blood pressure had to be lowered from ≈ 150-160 to ≈ 100-120 mm Hg. To lower NTG requirement, an α-2 agonist, clonidine, was administered (300 μg IV for 2 hours). Dyspnea, tachypnea, and tachycardia subsided for 1 to 2 hours, allowing to reduce NTG infusion to 2 to 4 mg h− 1 .

x Identifying the cause of acute dyspnea in the emergency department is often challenging, even for the most experienced provider. Distinguishing chronic obstructive pulmonary disease from acute decompensated heart failure in the acutely dyspneic patient who presents in respiratory distress is often difficult. Patients are often unable to give a detailed history when in extremis, yet primary management needs to be initiated before further testing can be completed. Bedside diagnostic ultrasound has emerged as a tool for emergency physicians to rapidly evaluate the cardiopulmonary status in patients presenting with undifferentiated shortness of breath [1-3].

x Adenosine is widely used for the treatment of supraventricular tachycardias for its efficacy and excellent safety, but it has been reported to precipitate severe bronchospasm in patients with pulmonary disease. The drug is therefore contraindicated in asthmatic subjects and should be used with caution in patients with chronic obstructive pulmonary disease. Nevertheless, true bronchospasm is rare and should be distinguished from the much more common occurrence of dyspnea, only as a symptom and without respiratory compromise, which is benign and transient.

x Anaphylaxis is an acute, lethal, multisystem syndrome that results from the sudden release of mast cell- and basophil-derived mediators. Although anaphylaxis can cause cardiac complications, the incidence of myocardial injury using troponin I (TnI) has not been characterized. In addition, patterns of cardiomyopathy have not been evaluated in patients with elevated TnI. Therefore, we studied the occurrence and patterns of myocardial injury with TnI and echocardiography in anaphylaxis.

x Despite advances in outpatient treatment and an improved understanding of the pathophysiology, asthma continues to be a significant source of morbidity and mortality in the United States. Although there is certainly a component of chronic inflammation, the majority of the symptoms in acute asthma exacerbations can be reversed with proper medications and management. Reversing bronchoconstriction and avoiding mechanical ventilation should be the goals of the emergency physician and the intensivist to avoid intubation and to view this intervention as a last resort.

x Prevention of secondary neurologic injury is critical during the airway management of a trauma patient. Trauma patients are assumed to have an unstable cervical spine (C-spine) until proven otherwise: orotracheal intubation during airway management may result in a certain amount of C-spine movement. This study, therefore, aimed to compare C-spine movement within different advanced airway devices (Macintosh blade, McCoy Blade, LMA, I-LMA, and Combitube) during airway management.

x Iatrogenic pneumothorax secondary to thoracentesis is relatively uncommon but does present to the emergency department (ED). Iatrogenic pneumothoraces developing tension physiology are rare. We report a case of an elderly female patient presenting to the ED with an isolated chief complaint of bilateral leg swelling, beginning the day after a thoracentesis, which was performed 3 days prior for pleural effusions secondary to lung cancer. Given that the patient was hemodynamically stable, not hypoxic, and had a history of chronic obstructive pulmonary disease and recent history of pleural effusions with diminished lung sounds throughout, this was a radiologic diagnosis.

x A recent systematic review and meta-analysis of randomized controlled trials of adrenaline use during resuscitation of out-of-hospital cardiac arrest found no benefit of adrenaline in survival to discharge or neurological outcomes. It did, however, find an advantage of standard dose adrenaline (SDA) over placebo and high dose adrenaline over SDA in overall survival to admission and return of spontaneous circulation (ROSC), which was also consistent with previous reviews. As a result, the question that remains is "Why is there no difference in the rate of survival to discharge when there are increased rates of ROSC and survival to admission in patients who receive adrenaline?" It was suggested that the lack of efficacy and effectiveness of adrenaline may be confounded by the quality of cardiopulmonary resuscitation (CPR) during cardiac arrest, which has been demonstrated in animal models.

x Humidification of inspired gas is critical in ventilated patients, usually achieved by heat and moisture exchange devices (HMEs). HME and the endotracheal tube (ETT) add airflow resistance. Ventilated patients are sometimes treated in hyperbaric chambers. Increased gas density may increase total airway resistance, peak pressures (PPs), and mechanical work of breathing (WOB). We tested the added WOB imposed by HMEs and various sizes of ETT under hyperbaric conditions. We mechanically ventilated 4 types of HMEs and 3 ETTs at 6 minute ventilation volumes (7-19.5 L/min) in a hyperbaric chamber at pressures of 1 to 6 atmospheres absolute (ATA).

x Rapidly progressive acute respiratory distress along with life-threatening gram-negative anaerobic sepsis in a young, immunocompetent individual should always raise concern for Lemierre's syndrome. Although still rare, the incidence of Lemierre's syndrome has been increasing over the past 20 years. Lemierre's syndrome is characterized by postanginal septicemia and secondary internal jugular vein suppurative thrombophlebitis. In the emergency department (ED), patients often present with evidence of sepsis and secondary septic emboli to different organs, primarily the lungs.

Here, we described a 37-year-old woman with acute hypoxic respiratory failure, acute renal failure, and hypercalcemic crisis as the presenting features of HIV-associated immune reconstitution syndrome. In this patient, the restored granulomatous host response toward isolated pulmonary Mycobacterium avium complex infection led to a near-fatal catastrophe.

x With the development of transportation technologies, elderly people with chronic diseases are increasingly enjoying trekking and tours of nature resorts that include mountain highlands. Because of problems related to circulation, respiration, metabolism, and/or the musculoskeletal system in this population, the impact of high altitude on cardiopulmonary function is increased. Alpine accidents, therefore, tend to be more common in this population, and cases of cardiopulmonary arrest (CPA) at high altitudes seem to be increasing.

x Spontaneous spinal epidural hematoma (SEH) is a rare disease. Furthermore, Brown-Séquard syndrome due to spontaneous SEH has been rarely reported. Early detection of spontaneous SEH is not easy because early symptoms are often atypical and neurologic findings are often absent in the early stage. Early diagnosis and urgent surgical management are needed to prevent permanent neurologic deficits. We report a case of a 30-year-old patient who presented with Brown-Séquard syndrome due to spontaneous SEH.

x Infective endocarditis is a rare but potentially deadly infection of the endocardial layer, which can involve the valves of the heart among other structures. The extraordinarily rare complication seen in this case involves extensive damage manifesting in an aortic root abscess resulting in an abnormal communication between the aorta and the atrium known as an aortocavitary fistula (Eur Heart J 2005;26:288-297; Pediatr Cardiol 2011;32:1057-1059; J Am Coll Cardiol 1991;18:663-667). As the disease progresses, wading through the complex symptoms, which may seem unrelated, represents a key challenge in diagnosis.

Physical examination revealed an afebrile man speaking in 2- to 3-word sentences with a firm, nontender, nonerythematous mass on the right side of his neck. A bedside ultrasound demonstrated a homogenous mass with internal vascular flow. This constellation of findings was felt to be most consistent with a malignancy. Nasopharyngoscopy confirmed a near obstructing supraglottic mass, and the patient underwent an emergent tracheostomy.

x Acute phosphate toxicity following rectal administration of phosphate-containing preparations was documented earlier. However, acute phosphate toxicity due to inhalation of monoammonium phosphate (MAP) is rarely reported. The present report describes the systemic toxicity following intentional inhalation of MAP, a dry chemical powder present in fire extinguishers, in a 25-year-old healthy man with normal renal function resulting in hyperphosphatemia (11.0 mg/dL), hypocalcemia (ionized calcium, 1.18 mg/dL; total calcium, 3.6 mg/dL), hypomagnesemia (1.2 mg/dL), seizures, and 4 episodes of pulseless polymorphic ventricular tachycardia requiring defibrillation.

x Diclofenac sodium is a 2-arylacetic acid, nonsteroidal anti-inflammatory drug. It is widely used in pain management. Side effects such as urticaria, asthmatic attack, vasospastic angina, ischemic stroke, and Kounis syndrome may be seen after the use of diclofenac sodium. However, anaphylactic shock is rare. Anaphylactic shock secondary to injection of diclofenac sodium can be treated successfully with intramuscular injection of adrenaline. Because diclofenac sodium is commonly used in analgesic treatment in emergency departments, we present this case report to emphasize that anaphylactic shock may be seen after the use of that drug.

x Endotracheal intubation is the “gold standard” of the control of airway patency but is associated with nonnegligible morbidity rates. A rapid detection of esophageal intubation is essential. Capnography is considered the reference technique for correct endotracheal tube (ETT) positioning confirmation. However, capnography can provide false-positive and false-negative results in some situations. Recently, the ultrasound assessment has been studied for confirming ETT placement. Despite of few trials, the ultrasound procedure may enhance physician confidence and decision making in airway management.

x The ultrasound-guided interscalene brachial plexus is becoming increasingly popular for anesthesia in the management of upper-extremity injuries by emergency physicians. Traditional high-volume injections of local anesthesia will also affect the phrenic nerve, leading to temporary paralysis of the ipsilateral hemidiaphragm. With direct ultrasound guidance, more precise needle placement allows for lower-volume injections that reduce inadvertent spread of local anesthetic to the phrenic nerve without decreasing the efficacy of onset of time and quality of the block.

x A previously healthy 21-year-old woman presented to the emergency department with a history of headache and 3 recent focal seizures. She was otherwise healthy and denied recent head trauma or infective symptoms. She denied pet ownership or foreign travel in the last 5 years. She was HIV negative during a recent prenatal screen. Her head and neck, cardiovascular, respiratory, and neurologic physical examinations were normal. Subsequent computed tomographic scan of the brain with intravenous contrast revealed a lesion consistent with Toxoplasma gondii brain abscess.

x The clinical findings related to carbon monoxide (CO) poisoning, which is one of the most mortal types of poisoning in the world, are associated with different tissues that are more sensitive to hypoxia such as the central nervous system and cardiovascular system. Carbon monoxide causes myocardial damage and arrhythmias by impairing the transport of oxygen. However, there have been few reported cases of CO poisoning–induced atrial fibrillation in the literature. In this article, a case of CO poisoning–induced atrial fibrillation and myocardial damage is presented.

x Approximately 7% of the US population abuses or is dependent on alcohol. Patients with alcohol disorders often seek medical attention in Emergency Departments (EDs) for complications directly related to alcohol use or due to other medical issues associated with alcohol use. Because of increasing lengths of stay in EDs, alcohol-dependent patients are at high risk of developing alcohol withdrawal syndrome (AWS) during their ED visit. This article reviews the physiology of alcohol withdrawal as well as the symptoms of this potentially deadly illness for the practicing emergency physician (EP).

x Patients are often referred to the emergency department for further evaluation, yet the astute physician will maintain a broad differential to avoid anchoring on prior diagnoses. In this case, a 56-year-old man was referred to our emergency department from the radiology suite secondary to concerns for an “allergic reaction” to prior magnetic resonance imaging contrast. Upon presentation, he was noted to have facial swelling with ruddy appearance and vascular congestion extending to the midchest region; no airway compromise or dyspnea was noted.

x Ventricular fibrillation (VF) and asphyxia account for most cardiac arrests but differ in cardiac arrest course, neurologic deficit, and myocardial damage. In VF resuscitation, cardiac mitochondria were known to be damaged via excess generation of reactive oxygen species. This study evaluated the difference of cardiac mitochondrial damages between VF and asphyxial cardiac arrests.

x Radiology plays an important role in evaluation of a trauma patient. Although chest radiography is recommended for initial evaluation of the trauma patient by the Advanced Trauma Life Support course, we hypothesized that precise physical examinations and history taking accurately identify those blunt trauma patients at low risk for chest injury, making routine radiographs unnecessary. Thus, this study was performed to investigate the role of chest radiography in initial evaluation of those trauma patients with normal physical examination.

x We describe a case of thyroid crisis with hypoglycemia, lactic acidosis, multiple organ failure, and disseminated intravascular coagulation—rare but severe complications of thyroid crisis. The patient was a 59-year-old Chinese woman who presented with evidence of heart failure and atrial fibrillation. Analysis of a blood sample yielded astonishing results: her blood glucose was 1.7 mmol/L, and lactate greater than 15 mmol/L with the arterial pH as 6.94. Liver enzymes (alanine aminotransferase, 1846 U/L; aspartate aminotransferase, 6242 U/L) and bilirubin elevated rapidly and dramatically.
