A young female vaper presented with insidious onset cough, progressive dyspnoea on exertion, fever, night sweats and was in respiratory failure when admitted to hospital. Clinical examination was unremarkable. Haematological tests revealed only thrombocytopenia, which was long standing, and her biochemical and inflammatory markers were normal. Chest radiograph and high-resolution CT showed diffuse ground-glass infiltrates with reticulation. She was initially treated with empirical steroids and there was improvement in her oxygenation, which facilitated further tests. Since the bronchoscopy and high-volume lavage was unyielding, a video-assisted thoracoscopicsurgical biopsy was done later and was suggestive of lipoid pneumonia. The only source of lipid was the vegetable glycerine found in e-cigarette (EC). Despite our advice to quit vaping, she continued to use EC with different flavours and there is not much improvement in her clinical and spirometric parameters.
A 42-year-old woman, presented to our emergency room with chief complaints of acute onset of dyspnea, left-sided chest pain, and respiratory distress. On arrival, she had blood pressure of 90/50 mm Hg, respiratory rate of 40/min, and oxygen saturation of 95% breathing on 10 L oxygen. She was in significant respiratory distress. On examination, she was found to have diminished breath sounds on the left side of chest. Her chest radiograph showed left massive pleural effusion causing contralateral shift of mediastinum. Diagnostic pleural aspiration was done; results were consistent with hemothorax. Her multidetector computed tomography chest showed features of left-sided hemothorax (high attenuation) along with a 2 cm-enhancing lobulated opacity in the left lingular lobe, suggestive of pulmonary arteriovenous malformation (PAVM). She was successfully treated with surgical resection of PAVM.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
