We describe the case of a male patient admitted to our emergency department during the Italian COVID-19 epidemic, for progressive worsening dyspnoea. A diagnosis of pneumothorax and diffuse interstitial lung involvement was promptly made by lung ultrasound and confirmed by an HRCT scan. A chest CT scan also showed diffuse emphysema, as observed in chronic obstructive pulmonary disease (COPD), and small consolidations in the lower lobes, suggestive for COVID-19 pneumonia. A chest tube was immediately inserted in the emergency room with complete resolution of the dyspnoea. A nasopharyngeal swab for 2019-nCoV was positive. Unfortunately, the patient died from COVID-19-related acute respiratory distress syndrome after 48 days of hospitalization.

Purpose: To understand the role of bronchoscopy in the treatment of chest CT images for patients with acute exacerbation of emphysema phenotype chronic obstructive pulmonary disease (COPD). Methods: 89 cases with chest CT images suggesting acute exacerbation of emphysema phenotype COPD were included and divided into the experimental group and the control group according to whether underwent bronchoscopy. Arterial blood gas indexes (pH value, PaO2, PaCO2), total glucocorticoid usage, length of stay, serum inflammatory factors (TNF-α, IL-6, IL-10) before and after treatment were compared between the two groups. Results: The hospitalization time of the experimental group was significantly shorter than that of the control group (11.88 ± 8.61 d vs. 16.50 ± 12.15 d, P = 0 045); the total use of methylprednisolone test group was 213.66 ± 32.07mg, and the control group was 250.83 ± 102.55 mg. The difference between the two groups was statistically significant (P = 0 028). The trend of repeated analysis of variance (F = 12 11,P = 0 001) were statistically significant. PaCO2 significantly decreased before and after the test in the experimental group (49.40 14.85 mmhg vs. 43.30 12.48 mmhg, P = 0.000). Plasma TNF-α and IL-6 decreased and IL-10 increased before and after the test. TNF-α and IL-6 increased and IL-10 decreased before and after the control group test, and the changes and trends of TNF-α, IL-6 and IL-10 before and after the two groups were statistically different (P = 0.000). These symptoms can be analyzed using CT imaging. Conclusion: In patients with acute exacerbation of emphysema phenotype COPD who are initially ineffective, bronchoscopy, alveolar lavage, and anti-contamination brush sampling guide anti-infective treatment can improve patient ventilation, and reduce glucocorticoid consumption.

Introduction The oral cavity and pharynx have a rich sensory system composed of specialized receptors. The integrity of oropharyngeal sensation is thought to be fundamental for safe and efficient swallowing. Chronic obstructive pulmonary disease (COPD) patients are at risk for oropharyngeal sensory impairment due to frequent use of inhaled medications and comorbidities including gastroesophageal reflux disease. Objective This study aimed to describe and compare oral and oropharyngeal sensory function measured using noninstrumental clinical methods in adults with COPD and healthy controls. Method Participants included 27 adults (18 men, nine women) with a diagnosis of COPD and a mean age of 66.56 years ( SD = 8.68). The control group comprised 11 healthy adults (five men, six women) with a mean age of 60.09 years ( SD = 11.57). Spirometry measures confirmed reduced functional expiratory volumes (% predicted) in the COPD patients compared to the control participants. All participants completed a case history interview and underwent clinical evaluation of oral and oropharyngeal sensation by a speech-language pathologist. The sensory evaluation explored the detection of tactile and temperature stimuli delivered by cotton swab to six locations in the oral cavity and two in the oropharynx as well as identification of the taste of stimuli administered in 5-ml boluses to the mouth. Analyses explored the frequencies of accurate responses regarding stimulus location, temperature and taste between groups, and between age groups (“≤ 65 years” and “> 65 years”) within the COPD cohort. Results We found significantly higher frequencies of reported use of inhaled medications ( p < .001) and xerostomia ( p = .003) in the COPD cohort. Oral cavity thermal sensation ( p = .009) was reduced in the COPD participants, and a significant age-related decline in gustatory sensation was found in the COPD group ( p = .018). Conclusion This study found that most of the measures of oral and oropharyngeal sensation remained intact in the COPD group. Oral thermal sensation was impaired in individuals with COPD, and reduced gustatory sensation was observed in the older COPD participants. Possible links between these results and the use of inhaled medication by individuals with COPD are discussed.
