Exploring the novel duo of Reticulocalbin, and Sideroflexin as future biomarker candidates for Exacerbated Chronic Obstructive Pulmonary Disease.

Background: COPD is a complex respiratory disorder with high morbidity and mortality rates. Even with the current conventional diagnostic methods, including circulating inflammatory biomarkers, underdiagnosis rates in COPD remain as high as 70%. Our study was a comparative cross-sectional study that aimed to address the diagnostic challenges by identifying future biomarker candidates in COPD variants.

Wegener's Granulomatosis: Are We Still Missing It?

We report the case of an 18-year-old female who was mis-diagnosed as a smear-negative pulmonary tuberculosis and advised standard antituberculosis treatment. She later presented with clinio-radiological worsening and thrombosis of superficial veins of the lower extremity. Cytoplasmic anti-neutrophil cytoplasmic antibody and computed tomography-guided lung biopsy confirmed the diagnosis of Wegener's granulomatosis.
