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.

Aims: To explore the feasibility of quantitative evaluation of pulmonary function in patients with chronic obstructive pulmonary disease (COPD) using tissue velocity imaging (TVI) and strain rate imaging (SRI) via transthoracic lung ultrasonography. Material and methods: Eighty inpatients with clinically diagnosed COPD underwent pulmonary function test and transthoracic lung ultrasound on the same day. Lung ultrasound variables and pulmonary function parameters were analyzed. Results: All patients with COPD had faster breathing and significant reduced lung function compared with healthy participants (p<0.05). The lung ultrasound parameters, velocity (max-min, cm/s), displacement (max-min, mm), strain (max-min, %) and strain rate (max-min, 1/s) were significantly higher in patients with COPD (p<0.05). A good negative correlation was found between lung ultrasound variables and pulmonary function parameters in patients with COPD. Stepwise multiple regression analysis indicated that the velocity (max-min, cm/s) was the only independent determinant of FEV1/FVC (%). With the use of FEV1/FVC<70% as the criteria of irreversible pulmonary function impairment to distinguish an abnormal pulmonary function, the area under the ROC was 0.99 for the velocity (max-min, cm/s) of the lung tissue in the process of breathing. The sensitivity, specificity, positive predictive value, negative predictive value and accuracy of the cut off value (1.19 cm/s) was 97.63%, 100%, 100%, 80%,  and 98%, respectively (p<0.001). Conclusions: Tissue velocity imaging via transthoracic lung ultrasound is a useful modality in the assessment of pulmonary function in patients with COPD.

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.
