Hypercapnia as an absolute exclusion criteria for bronchoscopic lung volume reduction.

Bronchoscopic lung volume reduction is a procedure that involves placement of valves into the lung to intentionally cause atelectasis to help with perfusion-ventilation matching. There are strict exclusion criteria, such as hypercapnia, that prevent patients from qualifying for the procedure based on the early trials. We present a case of a patient that became a candidate for the procedure after utilizing AVAPS after BPAP failed to lower his PCO2 to qualify for the procedure.

Necrotizing Granulomatous Infection Presenting as a Solitary Pulmonary Nodule: A Case Report and Review of the Literature.

is an opportunistic fungus that is classically associated with pneumonia in immunocompromised patients, particularly those with human immunodeficiency virus and acquired immunodeficiency syndrome (HIV/AIDS). However, this infection is now more commonly seen in those with malignancy, particularly lymphoproliferative disorders. Classic image findings with pneumonia (PJP) include bilateral ground-glass opacities with or without cyst formation.

Endobronchial Metastasis From Endometrial Carcinoma: A Case Report and Review of Literature.

Primary endometrial carcinoma presenting with endobronchial metastasis is quite rare. Little is known about predisposing risk factors, and the exact pathophysiologic mechanism remains unclear. The clinical presentation is non-specific, and symptoms likely vary depending on the disease burden.

Vitamin D Supplementation in COVID-19 Patients: A Clinical Case Series.

Background: Coronavirus disease 2019 (COVID-19) has infected more than 4.4 million people and caused more than 300,000 deaths partly through acute respiratory distress syndrome with propensity to affect African American and Hispanic communities disproportionately. Patients with worse outcomes have exhibited higher blood plasma levels of proinflammatory cytokines.
