###Human: How to go about the treatment in a patient with chronic cough? ###Assistant: Hello. Thanks for choosing this platform. As you said your mother is having chronic cough 4 months after surgery. It can be just coincidental finding as her x-ray (attachment removed to protect patient identity) is showing prominent basal vascular markings and cough can be aggravated by surgery. The x-ray findings are suggestive of interstitial lung disease called lung fibrosis which can be confirmed only after HRCT (high-resolution computed tomography) scan of chest. So at the earliest, I advise you to do HRCT scan of chest to rule out IPF (idiopathic pulmonary fibrosis). Once the diagnosis is made, treatment can be started accordingly. IPF or lung fibrosis is a chronic and progressive condition. So, diagnosis should be made as early as possible.Talk to your pulmonologist regarding further investigations and treatment. He will guide you better as frequent follow-up visits are required for monitoring the disease. Autoimmunity. HRCT chest to rule out IPF. Interstitial pneumonia. IPF (idiopathic pulmonary fibrosis). 1. Steroids 2. Immunosuppressants. Strict control of BP and blood sugar is a must.
