Write answer in between .Q:A 43-year-old man with a history of chronic alcoholism presents with a chronic cough and dyspnea. He says he traveled to Asia about 4 months ago and his symptoms started shortly after he returned. His temperature is 40.2C 104.4F and pulse is 92min. Physical examination reveals poor personal hygiene and a cough productive of foul blood-streaked sputum. Auscultation reveals decreased breath sounds on the right. A chest radiograph reveals an ill-defined circular lesion in the right middle lobe. Which of the following is true regarding this patients most likely diagnosis?? A: Stains of gastric washing and urine have a high diagnostic yield on microscopy., B: Inoculation of a sputum sample into selective agar media needs to be incubated at 3537C 95.098.6F for up to 8 weeks., C: Ziehl-Neelsen staining is more sensitive than fluorescence microscopy with auramine-rhodamine stain., D: DNA polymerase chain reaction PCR has poor sensitivity when applied to smear positive specimens., E: A positive tuberculin test would be diagnostic of active infection.,  <response>: This is a clinical vignette describing a patient with chronic alcoholism who recently traveled to Asia and now presents with fever, cough, and abnormal lung imaging concerning for an infectious process. The question asks about the most likely diagnosis for this patient. Based on the patients symptoms, travel history, and chest x-ray findings of a lesion in the right middle lobe, the most likely diagnosis is pulmonary tuberculosis. Key facts about diagnosing TB include:- Gastric washing and urine microscopy have low diagnostic yield for TB. - Sputum cultures require extended incubation at 35-37C on selective media like Lowenstein-Jensen. - Fluorescence microscopy with auramine-rhodamine is more sensitive than Ziehl-Neelsen staining for detecting acid-fast bacilli.- PCR has high sensitivity when applied to smear-positive specimens.- A positive tuberculin skin test indicates previous exposure, not necessarily active TB infection.B: Inoculation of a sputum sample into selective agar media needs to be incubated at 3537C 95.098.6F for up to 8 weeks.
