The study results revealed significant average, nasal RNFL, global GCL+ loss, and a nonsignificant choroidal thinning in patients with COPD compared to healthy subjects. The eye seems to be one of the affected tissues during the natural course of the COPD.

In this article, 11 cases with various rarely seen complications are presented and evaluated in the light of current literature. We recommend that if chronic cough, recurrent pulmonary infections, and bronchiectasis seen in a patient, MKS should be kept in mind.

Obstructive fibrinous tracheal pseudomembrane is a rare but potentially fatal complication associated with endotracheal intubation. Little is known about the mechanisms that play a role in the development of tracheal pseudomembrane, but it requires early diagnosis and treatment to prevent its major consequences. In this report, we present a case of obstructive fibrinous tracheal pseudomembrane, which developed a day after extubation in a patient who was intubated for 2 days. Therapeutic bronchoscopy was highly successful in removing the lesion and improving the clinical course.

The COVID-19 pandemic has brought countries’ health services into sharp focus. It was drawn to our group’s attention that healthcare workers (HCWs) had a lower mortality rate against higher COVID-19 incidence compared to the general population in Turkey. Since risk of exposure to tuberculosis bacillus among healthcare workers are higher than the population, we aimed to investigate if there is a relationship between BCG and Mycobacterium tuberculosis exposure history with COVID-19 severity in infected HCWs. This study was conducted with 465 infected HCWs from thirty-three hospitals to assess the relationship between COVID-19 severity (according to their hospitalization status and the presence of radiological pneumonia) and BCG and Mycobacterium tuberculosis exposure history. HCWs who required hospital admission had significantly higher rates of chronic diseases, radiological pneumonia, and longer working hours in the clinics. Higher rates of history of contact and care to tuberculosis patients, history of tuberculosis, and BCG vaccine were observed in hospitalized HCWs. HCWs who had radiological pneumonia had a significantly increased ratio of history of care to tuberculosis patients and a higher family history of tuberculosis. The findings from our study suggest that the lower mortality rate despite the more severe disease course seen in infected HCWs might be due to frequent exposure to tuberculosis bacillus and the mortality-reducing effects of the BCG vaccine.
