OBJECTIVES: We hypothesized that preferential retropalatal as compared to retroglossal collapse in patients with obstructive sleep apnea was due to a narrower retropalatal area and a higher retropalatal compliance. Patients with a greater retropalatal compliance would exhibit a recognizable increase in negative effort dependence (NED). METHODS: Fourteen patients underwent upper airway endoscopy with simultaneous recordings of airflow and pharyngeal pressure during natural sleep...

Aim: The main aim is to determine whether growth pattern had an effect on the upper airway by comparing different craniofacial patterns with pharyngeal widths and its importance during the clinical examination. Methodology: Sixty lateral cephalograms of patients aged between 16 and 24 years with no pharyngeal pathology or nasal obstruction were selected for the study. These were divided into skeletal Class I ( n = 30) and skeletal Class II ( n = 30) using ANB angle subdivided into normodivergent, hyperdivergent, and hypodivergent facial patterns based on SN-GoGn angle...

OBJECTIVE: Both myopathic and neuropathic tongue protruder muscle changes have been demonstrated to occur in obstructive sleep apnea (OSA) patients using different methods. We tried to elucidate this dilemma using quantitative electromyographic (EMG) methods. METHODS: In a group of consecutive patients with suspected OSA a full overnight polysomnography (PSG) and quantitative needle EMG of the tongue protruder, biceps brachii and vastus lateralis muscles were performed...

BACKGROUND: To evaluate the safety and efficacy of a novel radioactive bare metal stent (RBMS) compared with a conventional bare metal stent (CBMS) in patients with inoperable malignant airway obstruction. METHODS: This prospective study was approved by the Institutional Ethics Committee, and informed consent was obtained from each participant. Patients with malignant airway obstruction who had dyspnea were randomly assigned to receive RBMS or CBMS placement. The primary endpoint was stenosis grade, while the secondary endpoints were technical success, overall survival, and complications...

Subglottic hemangioma is a rare benign tumor in children. It causes an obstruction of the upper airway and can be life-threatening. Several therapeutic options have been used in the literature, including surgery. Currently, the treatment is essentially based on propranolol. We report the case of a 2-month-old female infant hospitalized for severe obstructive dyspnea secondary to a subglottic hemangioma. Diagnosis was confirmed by laryngoscopy and magnetic resonance imaging. The child underwent a tracheotomy and was treated with propranolol...

Vernagel (sodium polyacrylate) is a powder commonly used in hospitals worldwide for the management and disposal of body fluids. It reacts with fluids to form a semisolid gel. Its main use is to reduce spillages. If ingested, this substance presents significant risk of asphyxiation. There have been 15 reported cases of Vernagel ingestion in 6 years and 1 death from asphyxiation. We present the case of an elderly patient who was admitted following a fall. He accidentally ingested a sachet of Vernagel during the early hours of the morning...

The exact role of fractional exhaled nitric oxide (FeNO) in older patients with chronic inflammatory diseases including asthma-chronic obstructive pulmonary disease (COPD) overlap (ACO) remains unclear. This study aimed to investigate the differences in FeNO levels of elderly patients with ACO, asthma, COPD, and chronic cough. We conducted a retrospective study analysing the data of stable outpatients from Pulmonary Department of the Second Clinical College, Jinan University. All participants (Age≥55 years) were divided into the ACO group (n=19), asthma group (n=16), COPD group (n=25), and chronic cough group (n=22)...

Danger-associated molecular patterns (DAMPs) play a proinflammatory role in the pathogenesis of airway obstructive diseases such as severe asthma and chronic obstructive pulmonary disease. The NLRP3 inflammasome is a cytosolic multiprotein platform that activates the caspase-1 pathway in response to inflammatory stimuli such as DAMPs. ATP and S100 proteins are newly identified DAMPs that accumulate in inflamed airways. We previously demonstrated that S100A8, S100A9, and S100A12 induce production and secretion of MUC5AC, a major mucin in the conducting airway mucosa...

INTRODUCTION: Treacher Collins syndrome (TC) and Pierre Robin sequence (RS) are associated with hypoplastic mandible, glossoptosis, and consequent airway obstruction. Although TC and RS are often grouped together, airway outcomes of bilateral mandibular distraction osteogenesis (MDO) have not been specifically studied in TC. The purpose of this study is to report on the clinical outcomes of MDO in the TC patient population. MATERIALS AND METHODS: A twenty-year single-institution retrospective review of all patients with TC who underwent bilateral MDO was performed...

Airway remodeling (AR) is a progressive pathological feature of the obstructive lung diseases, including asthma and chronic obstructive pulmonary disease (COPD). The pathology manifests itself in the form of significant, progressive, and (to date) seemingly irreversible changes to distinct respiratory structural compartments. Consequently, AR correlates with disease severity and the gradual decline in pulmonary function associated with asthma and COPD. Although current asthma/COPD drugs manage airway contraction and inflammation, none of these effectively prevent or reverse features of AR...

Teratomas are rare congenital tumors typically comprising all 3 germ cell layers. Cervical teratomas arise in the neck and represent a minority of all teratomas. These are associated with high morbidity and mortality because of their propensity to cause airway obstruction. Demonstration on prenatal magnetic resonance imaging is uncommon, especially for a tumor of this size. Fetuses diagnosed with large neck masses are managed through cesarean section with the ex utero intrapartum treatment procedure to secure the airway, such as in our case of a large cervical teratoma in the female fetus of a 30-year-old mother who went into preterm labor...

We investigated whether the combination of increased fraction of exhaled nitric oxide (FeNO) level and blood eosinophil count had an additive value in chronic airway disease in the general population.We included 4677 individuals aged 20-100 years from the Copenhagen General Population Study. Based on pre- and post-bronchodilator spirometry, self-reported asthma, and smoking history, participants were subdivided into:healthy never-smokers (n=1649), healthy ever-smokers (n=1581), asthma (n=449), chronic obstructive pulmonary disease (COPD) (n=404), asthma-COPD overlap (ACO) (n=138), and non-specific airflow limitation (n=456)...

OBJECTIVE: Obesity is associated with a high incidence of obstructive sleep apnoea (OSA). Bariatric surgery is postulated to lead to OSA resolution, but there is inconclusive evidence on its efficacy. We used objective measurements to determine the rate of resolution or improvement of OSA in patients who had bariatric procedures in our unit. RESULTS: Data was analysed on all patients with OSA who underwent bariatric procedures [laparoscopic Roux-en-Y gastric bypass (LRYGB) and sleeve gastrectomy (LSG)] between June 2012 and September 2016 in our unit...

BACKGROUND: Nasal congestion and obstruction are reported in the majority of continuous positive airway pressure (CPAP) users and are frequently cited as reasons for noncompliance. To our knowledge, no study has demonstrated a change in objective or subjective nasal patency in patients with obstructive sleep apnea (OSA) after a therapeutic trial of CPAP therapy. METHODS: This prospective nonrandomized trial tested the hypothesis that CPAP therapy would result in both objective and subjective improvements in nasal patency in patients with OSA...

Obstructive sleep apnea (OSA) is a common disorder characterized by episodic obstruction to breathing due to upper airway collapse during sleep. Because of the episodic airway obstruction, intermittently low O2 (hypoxia) and high CO2 (hypercapnia) ensue. OSA has been associated with adverse cardiovascular and metabolic outcomes, although data regarding potential causal pathways are still evolving. As changes in inspired O2 and CO2 can affect the ecology of the gut microbiota and the microbiota has been shown to contribute to various cardiometabolic disorders, we hypothesized that OSA alters the gut ecosystem, which, in turn, exacerbates the downstream physiological consequences...

BACKGROUND: Cystic fibrosis (CF) is the most common, life-limiting, genetically inherited disease. It affects multiple organs, particularly the respiratory system. However, gastrointestinal problems such as constipation and distal intestinal obstruction syndrome (DIOS) are also important and well-recognised complications in CF. They share similar symptoms e.g. bloating, abdominal pain, but are distinct conditions. Constipation occurs when there is gradual faecal impaction of the colon, but DIOS occurs when there is an accumulation of faeces and sticky mucus, forming a mass in the distal part of the small intestine...
