We report a case of bronchostenosis manifested as an asymptomatic mass on preoperative chest roentgenogram. Bronchoscopic biopsy inadvertently led to drainage of the obstructed bronchus. The various pathogenic origins of bronchostenosis are discussed, with the most likely cause in this case being previous tuberculosis.

Introduction: Amyloidosis, a polymeric deposition disease classified according to protein subtype, may have varied pulmonary manifestations. Its anatomic-radiologic phenotypes include nodular, cystic, alveolar-septal, and tracheobronchial forms. Clinical presentation may range from asymptomatic parenchymal nodules to respiratory failure from diffuse parenchymal infiltration or diaphragmatic deposition.

Background: Neurocysticercosis (NCC) and Acquired Human Immunodeficiency Syndrome (AIDS) are both highly prevalent in Africa. Clinical presentation of NCC ranges from asymptomatic to manifestations, including epileptic seizures, severe progressive headache, and focal neurological deficits. It is influenced by the number, size, location, and stage of the cysts, as well as the parasite's potential to cause inflammation and the immunological response of the host.

Vitamin K is essential to produce functional vitamin K-dependent coagulation factors (prothrombin, factors VII, IX, and X). Vitamin K antagonists inhibit the normal activation of these factors, leading to bleeding manifestations of variable severity. Long-acting vitamin K antagonists or superwarfarins were developed as rodenticides and have a significantly longer half-life and greater potency when compared to warfarin.

Chickens are a key species in both the manifestation of avian influenza and the potential for zoonotic transmission. Avian influenza virus (AIV) infection in chickens can range from asymptomatic or mild disease with low pathogenic AIVs (LPAIVs) to systemic fatal disease with high pathogenic AIVs (HPAIVs). During AIV infection in chickens, Toll-like receptor 7 and melanoma differentiation-associated gene 5 are upregulated to detect the single-stranded ribonucleic acid genomes of AIV, triggering a signaling cascade that produces interferons (IFNs) and pro-inflammatory cytokines.
