Can 1st and 6th month pulmonary function test follow-ups give an idea about the long-term respiratory effects of COVID-19 pneumonia?

SUMMARY OBJECTIVE: The aim of this study was to ascertain the long-term respiratory effects of COVID-19 pneumonia through pulmonary function tests in follow-ups at 1 and 6 months. METHODS: Our study was conducted between August 1, 2020 and April 30, 2021. At 1 month after discharge, follow-up evaluations, PFTs, and lung imaging were performed on patients aged above 18 years who had been diagnosed with COVID-19 pneumonia. In the 6th month, the PFTs were repeated for those with pulmonary dysfunction. RESULTS: A total of 219 patients (mean age, 49±11.9 years) were included. Pathological PFT results were noted in the 1st month for 80 patients and in the 6th month for 46 (7 had obstructive disorder, 15 had restrictive disorder, and 28 had small airway obstruction) patients. A significant difference was found between abnormal PFT results and patient-described dyspnea in the 1st month of follow-up. The 6-month PFT values (especially those for forced vital capacity) were statistically significantly lower in the patients for whom imaging did not indicate complete radiological improvement at the 1-month follow-up. No statistically significant difference was found between the severity of the first computed tomography findings or clinical condition on emergency admission and pulmonary dysfunction (Pearson's chi-square test, P=0.904; Fisher's exact test, P=0.727). CONCLUSION: It is important that patients with COVID-19 pneumonia be followed up for at least 1 month after discharge to be monitored for potential long-term lung damage. PFTs should be administered to those in whom ongoing dyspnea, which started with COVID-19, and/or full recovery were not identified in pulmonary imaging.

Barotraumatic Subcutaneous Orbital Emphysema after Nose Blowing: Case Report.

Orbital subcutaneous emphysema is defined as the abnormal presence of air within the periorbital soft tissue. It occurs generally as a result of blunt or penetrating facial trauma. Spontaneous barotraumatic emphysema is a very rare entity that generally results due to a sudden increase in the intraorbital pressure. If there is not an obvious visual acuity loss even with high ocular pressure, it is generally managed conservatively. However prolonged elevation of intraorbital pressure may cause an irreversible, ischemic visual loss secondary to an ischemic optic neuropathy or an acute central retinal artery occlusion. Emergency decompression may be required. Here we are presenting a patient with barotraumatic orbital subcutaneous emphysema, occurring after forceful nose blowing who was managed conservatively without any complications.
