Background The evaluation of COVID‐19 systemic consequences is a wide research field in which respiratory function assessment has a pivotal role. However, the available data in the literature are still sparse and need further strengthening. Aim To assess respiratory function 4–6 months after hospital discharge based on lung disease severity in patients who overcome COVID‐19 pneumonia. Methods Patients hospitalised either in the Internal Medicine Department (IMD) for moderate to severe disease or in the Intensive Care Unit (ICU) for critical disease underwent spirometry with maximal flow‐volume curve, lung volumes, lung diffusion capacity (DL CO ) and six‐minute walking test (6‐MWT). Results Eighty‐eight patients were analysed: 40 from the IMD and 48 from the ICU. In both cohorts, there was a greater prevalence of male patients. In the IMD cohort, 38% of patients showed at least one altered respiratory parameter, while 62% in the ICU cohort did so ( P < 0.05). Total lung capacity (TLC) and DL CO were the most frequently altered parameters: 15% and 33% from IMD versus 33% and 56% from ICU, respectively ( P < 0.05). In IMD patients, 5% had only restrictive deficit, 22% had only lung diffusion impairment and 10% had both. In ICU patients, 6% had only restrictive deficit, 29% had only lung diffusion impairment and 27% had both ( P < 0.05). ICU patients showed a higher frequency of abnormal 6‐MWT ( P < 0.05). Conclusion Lung function tests and 6‐MWT are highly informative tools for monitoring the negative consequences of COVID‐19 pneumonia, which were more frequent and more complex in patients discharged from ICU.

Angiosarcoma is a rare malignancy of vascular origin, mostly originating from skin, soft tissues, and breast, but rarely also from the pleura. We present the case of a 55-year-old man who referred to our hospital for a spontaneous bilateral hemothorax. The CT angiography did not show any source of active bleeding; plus, no pleural or lung masses were observable. Cytological and microbiological analyses made on a sample of pleural fluid resulted negative. Despite numerous blood transfusions and thoracenteses, the patient deceased from hemorrhagic shock ten days later and the diagnosis of primary pleural epithelioid angiosarcoma was obtained only by autopsy. Additionally, we present a review of the literature about primary pleural angiosarcomas.

Purpose In patients with chronic obstructive pulmonary disease (COPD), bronchial responsiveness after acute administration of short acting bronchodilators is conventionally assessed by measuring the improvement of forced expiratory volume in the first second (FEV1) during a maximal forced expiratory maneuver. This study aimed to measure the variation of intrathoracic airway wall compliance (AWC) after acute administration of short acting beta-2 agonist in COPD patients since this might influence the final modification of airway caliber during maximal expiratory effort and the resulting bronchodilation as inferred by FEV1 changes. Methods In a group of 10 patients suffering from COPD, intrathoracic AWC was measured at middle (50% of Forced Vital Capacity (FVC) and low (75% of FVC) lung volumes using the interrupter method during forced expiratory maneuver in basal conditions and after acute inhalation of albuterol (salbutamol) (400 mcg by MDI). Ten healthy subjects were examined similarly as a control group. Results Lower values of baseline intrathoracic AWC at both lung volumes were found in COPD patients (1.72 ± 0.20 ml/cmH2O and 1.08 ± 0.20 ml/cmH2O, respectively) as compared to controls (2.28 ± 0.27 ml/cmH2O and 1.44 ± 0.22 ml/cmH2O, respectively) (p < 0.001). In COPD patients, AWC increased significantly at both lung volumes after salbutamol, amounting to 1.81 ± 0.38 ml/cmH2O and 1.31 ± 0.39 ml/cmH2O, respectively (p < 0.01), but the relative change was not different from that observed in controls. Conclusion In COPD patients, AWC is reduced compared to controls, but after bronchodilator, the intrathoracic airways become more compliant. The consequent increased collapsibility under high positive pleural pressure could limit the airway caliber improvement seen after bronchodilator, as assessed by the FEV1 changes during the forced expiratory maneuver, underestimating the effective bronchodilation achieved in these patients.
