BACKGROUND: The development of supraglottic airway devices has revolutionized airway management during general anaesthesia. Two devices are widely used in clinical practice to facilitate positive pressure ventilation: the ProSeal laryngeal mask airway (pLMA) and the Classic laryngeal mask airway (cLMA). It is not clear whether these devices have important clinical differences in terms of efficacy or complications. OBJECTIVES: To compare the effectiveness of the ProSeal laryngeal mask airway (pLMA) and the Classic LMA (cLMA) for positive pressure ventilation in adults undergoing elective surgery...

A previously healthy 7-month-old male infant presented for evaluation of fever, deceased oral intake, and intermittent noisy breathing. Physical examination revealed neck tenderness. Soft tissue neck radiographs and computed tomography (CT) scan supported a diagnosis of retropharyngeal swelling with extension to the superior mediastinum. Surgical exploration was planned, and endotracheal intubation was performed in the operating room. Significant cardiorespiratory derangements developed immediately after the tracheal tube was inserted, including hypotension, hypoxia, and bradycardia with signs of cardiac ischemia...

BACKGROUND: Childhood asthma is a substantial health burden in Thailand. Due to a lack of pediatric respiratory specialists (pediatric pulmonologists and allergists; RS), most Thai children are cared for by general pediatricians (pediatric primary care providers (PCP)). OBJECTIVES: We investigated whether current practices of Thai pediatricians complied with asthma guidelines and compared practices (diagnosis and treatments) provided by PCP and RS. METHODS: A cross-sectional study was conducted using electronic surveys including four case scenarios of different asthma phenotypes distributed to Thai pediatricians...

BACKGROUND: In early 2015, clinicians throughout Zambia noted a range of unpredictable adverse events after the administration of propofol, including urticaria, bronchospasm, profound hypotension, and most predictably an inadequate depth of anesthesia. Suspecting that the propofol itself may have been substandard, samples were procured and sent for testing. METHODS: Three vials from 2 different batches were analyzed using gas chromatography-mass spectrometry methods at the John L...

PURPOSE: Systemic absorption and central nervous system (CNS) penetration of timolol drops are a well-studied phenomenon, resulting in common side effects such as bradycardia, bronchospasm, fatigue, and confusion. More serious CNS side effects, such as psychosis and depression, however, are rarely attributed to eye drops. We report a case series in which patients developed visual hallucinations secondary to topical ocular timolol use. METHODS: This study is a case series and review of the literature...

Cough variant asthma (CVA), as one of bronchitis diseases, features with repeated cough. In clinics, CAV does not show significant abnormal signs, therefore antibiotic therapy can hardly achieve satisfactory treatment effect. With the development of scientific technologies, the correlation between mycoplasma pneumoniae infection and CVA has become a hot research topic in clinics. In clinics, mycoplasma pneumoniae is extensively regarded as major cause for CVA, with complex pathogenic mechanism. The symptoms of CVA is characterized by chronic non abnormal inflammation, normally accompanied with bronchospasm and intestinal infection...

There is an increase in the prevalence of asthma and obesity, constituting a public health problem at national and global levels. The association between the two pathologies has not been clearly determined; however, a certain synergy has been proposed, which leads to more severe bronchospasms, longer recovery time, and more prolonged use of medications in obese asthmatic patients. The discovery of leptin, an adipokine that is directly related to the amount of total body fat and the production of proinflammatory cytokines, has generated greater interest in white adipose tissue...

Gastroenteropancreatic neuroendocrine tumors (GEP-NETs) are rare malignancies that originate in the gastrointestinal system. GEP-NETs are typically indolent, but tumors known as "functional" secrete hormones that can lead to a complex of symptoms, including flushing, diarrhea, bronchospasm, and valvular heart disease. Management of patients with GEP-NETs requires a multidisciplinary approach, as treatment modalities include surgery, radiology, and pharmacotherapy. The available pharmacologic agents have increased in recently, and now include cytotoxic chemotherapies, somatostatin analogues, multitargeted tyrosine kinase inhibitors, mammalian target of rapamycin inhibitors, and radioisotopic radiotherapies...

Drug hypersensitivity reactions (RHD) are those that present clinically as allergic. They can or cannot involve an immunologic mechanism of lesion. They are frequent and, occasionally, life threatening. Patients with RHD repeat the reaction when they are re-exposed to the drug, limiting the therapeutic options and exposing them to more expensive and toxic drugs. It is difficult to identify the responsible drug when the reaction was not recent or when it occurred in the context of therapy with multiple drugs or confusing concurrent diseases...

Sport is an essential part of childhood, with precious and acknowledged positive health effects but the impact of exercise-induced bronchoconstriction (EIB) significantly reduces participation in physical activity. It is important to recognize EIB, differentiating EIB with or without asthma if the transient narrowing of the airways after exercise is associated with asthmatic symptoms or not, in the way to select the most appropriate treatment among the many treatment options available today. Therapy is prescribed based on symptoms severity but diagnosis of EIB is established by changes in lung function provoked by exercise evaluating by direct and indirect tests...

Carcinoid syndrome is the constellation of symptoms mediated by humoral factors produced by some carcinoid tumors. It consists primarily of vasomotor symptoms, gastrointestinal hypermotility, hypotension, and bronchospasm, due to the production and release of vasoactive substances. Carcinoid heart disease occurs in more than 50% of patients with carcinoid syndrome; in some cases, it represents the initial manifestation of the disease. We report the case of a 75-year-old woman with a metastatic neuroendocrine tumor admitted to the emergency room for fatigue and heart failure...

BACKGROUND: Beta-blockers are commonly prescribed for patients with cardiovascular disease. Providers have been wary of treating chronic obstructive pulmonary disease (COPD) patients with beta-blockers due to concern for bronchospasm, but retrospective studies have shown that cardio-selective beta-blockers are safe in COPD and possibly beneficial. However, these benefits may reflect symptom improvements due to the cardiac effects of the medication. The purpose of this study is to evaluate associations between beta-blocker use and both exacerbation rates and longitudinal measures of lung function in two well-characterized COPD cohorts...

In severe cases of status asthmaticus, when conventional therapies fail, volatile anesthetic agents remain a therapeutic option. When delivered outside of the operating room setting, specialized delivery techniques are needed to ensure the safe and effective use of volatile anesthetic agents. We present a 16-year-old adolescent with status asthmaticus who required the therapeutic administration of the volatile anesthetic agent, sevoflurane, in the pediatric intensive care unit (PICU). Although initially effective in reducing bronchospasm, progressive hypercarbia developed due to defective functioning of the carbon dioxide absorber of the anesthesia machine...

Rare neuroendocrine tumours (NETs) that most commonly arise in the gastrointestinal tract can lead to carcinoid syndrome and carcinoid heart disease. Patients with carcinoid syndrome present with vasomotor changes, hypermotility of the gastrointestinal system, hypotension and bronchospasm. Medical therapy for carcinoid syndrome, typically with somatostatin analogues, can help control symptoms, inhibit tumour progression and prolong survival. Carcinoid heart disease occurs in more than 50% of these patients and is the initial presentation of carcinoid syndrome in up to 20% of patients...

Approximately 60% of perioperative anaphylactic reactions are thought to be immunoglobulin IgE mediated, whereas 40% are thought to be non-IgE mediated hypersensitivity reactions (both considered non-dose-related type B adverse drug reactions). In both cases, symptoms are elicited by mast cell degranulation. Also, pharmacological reactions to drugs (type A, dose-related) may sometimes mimic symptoms triggered by mast cell degranulation. In case of hypotension, bronchospasm, or urticarial rash due to mast cell degranulation, identification of the responsible mechanism is complicated...

Adenosine is increasingly used to assess for dormant conduction following pulmonary vein isolation during atrial fibrillation ablation. While the half-life of adenosine is typically short and side effects transient, operators should be aware of more serious, lasting adverse reactions including anaphylaxis and bronchospasm.

BACKGROUND/OBJECTIVES: The nonselective beta-blocker propranolol is the current criterion standard for treatment of infantile hemangiomas (IHs) and the first therapy that the U.S. Food and Drug Administration has approved for the condition, but concern about adverse effects, such as bronchospasm, hypoglycemia, and sleep disturbances, has sparked interest in the use of alternative agents such as the selective β1 antagonist atenolol. Our aim was to compare the efficacy and adverse effect profiles of atenolol with those of propranolol in the treatment of IHs in a retrospective noninferiority trial...

BACKGROUND/AIM: Acidification of exhaled breath condensate (EBC), reflecting airway inflammation and oxidative stress, has been reported in lung cancer patients undergoing lobectomy. We undertook this study to examine EBC pH changes during surgery for abdominal cancer. PATIENTS AND METHODS: EBC pH was measured from 20 patients undergoing abdominal cancer resection before and during surgery. Repeated-measures of ANOVA and random-effects linear models were applied to compare mean EBC pH values in samples collected at different times...
