New twist to an old problem: COVID-19 and idiopathic pulmonary fibrosis.

Iidiopathic pulmonary fibrosis (IPF) diagnosis and treatment during this COVID-19 pandemic have been affected. COVID-19 has not only impacted the prognosis of these patients but also the approach to these patients. Pulmonary function tests (PFT) and lung biopsies are less encouraged now. Traditional antifibrotics used in IPF should be encouraged irrespective of patient lung function and in those with non-definite usual interstitial pneumonia in high resolution computed tomography.

An unusual cause of high density radiological opacities.

INTRODUCTION: Metallic mercury poisoning through intravenous injection is rare, especially as part of a suicide attempt. Diagnosis and treatment of the disease are challenging as clinical features are not specific. MATERIAL AND METODS: A 41-year-old male presented with dyspnea, fatigue, loss of weight, and loss of appetite over two months. Routine radiological examination by chest X-ray and CT showed randomly distributed high density opacities with Hounsfield units (HU) around 500 HU all over the body. The diagnosis was then confirmed with a urinary mercury concentration of > 1000 mcg/24 h. RESULTS: The patient's clinical condition was getting worse in spite of chelation therapy and hemodialysis. The patient eventually died because of respiratory failure. CONCLUSION: Early diagnosis and appropriate treatment are critical for intravenous mercury poisoning especially because there are no specific signs or symptoms. There should be a high level of suspicion in drug abusers. Treatment should involve the combined use of chelating agents and other treatments such as hemodialysis and plasma exchange in advanced clinical settings.
