ObjectiveHuman activities associated with aerosol-generating hot water sources are increasingly popular. Recently, a hypersensitivity pneumonitis (HP)-like granulomatous lung disease, with non-tuberculous mycobacteria from exposure to hot water aerosols from hot tubs/spas, showers, and indoor swimming pools, has been described in immunocompetent individuals (also called “hot tub lung”). Our objective in this study was to examine four additional cases of hot tub lung and compare these cases with others reported in the English print literature on this disease.Data sources and extractionWe retrospectively reviewed all cases (n = 4) of presumptively diagnosed hot tub lung in immunocompetent individuals at the various physician practices in Springfield, Illinois, during 2001–2005. In addition, we searched MEDLINE for cases of hot tub lung described in the literature.Data synthesisWe summarized the clinical presentation and investigations of four presumptive cases and reviewed previously reported cases of hot tub lung.ConclusionsThere is a debate in the literature whether hot tub lung is an HP or a direct infection of the lung by nontuberculous mycobacteria. Primary prevention of this disease relies on ventilation and good use practices. Secondary prevention of this disease requires education of both the general public and clinicians to allow for the early diagnosis of this disease.
Vasculitis refers to inflammation of the systemic vessels. Eosinophilic granulomatosis with polyangiitis (EGPA) is a medium and small vessel vasculitis characterized by hypereosinophilia, pulmonary infiltrates, difficult to treat asthma and polyneuropathies. Diagnosis can often be challenging. In this article, we present a case of a young lady who was diagnosed ANCA negative EGPA.
BackgroundCushing's syndrome due to ectopic ACTH secretion has been associated with many cancers; most commonly small cell carcinoma of the lung and bronchial carcinoid tumors. Usually, patients who confer this diagnosis have poor prognosis.Case presentationA 66-year-old female presented with worsening shortness of breath and weakness over three days. Initial laboratory derangements included severe hypokalemia and metabolic alkalosis. Treatment included high amounts of potassium chloride and acetazolamide. Imaging studies revealed anterior medial right upper lobe lung mass as well as suspicion for many liver metastases. Liver biopsy was sought and was positive for small cell carcinoma.ConclusionWe describe a case of severe metabolic alkalosis and hypokalemia in a patient with Cushing's syndrome due to ectopic ACTH secretion from small cell lung cancer. To our knowledge, this is the first case identified which exhibited such significant metabolic derangements in the form of serum and arterial blood bicarbonate. As prognosis is quite poor, we recommend swift diagnosis and management.
The Coronavirus Disease 2019 (COVID-19) pandemic has displayed heterogeneity in disease manifestations and complications; cardiac, renal, neurological complications and coagulopathy are reported. We present a case of COVID-19 with pneumomediastinum.
We report an interesting case of a patient presenting with cardiac arrest secondary to hypoxemia who was found to have bilateral pulmonary nodular opacities and idiopathic CD4 lymphopenia.
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.
