ABSTRACT
e-Cigarettes have gained worldwide popularity as a substitute for smoking, but concern has been raised regarding the long-term effects associated with their use. We report a case of a 45-year-old female consumer of e-cigarettes who presented with 4 months of abdominal pain and fever. Initial imaging discovered multiple pulmonary nodules and liver lesions suspicious of widespread metastases; however, an extensive evaluation found no evidence of malignancy. Results of a lung biopsy revealed an area with multinucleated giant cells suggestive of a foreign body reaction to a lipophilic material. Upon cessation of e-cigarette use (known as vaping), the lung nodules disappeared, and the liver lesions regressed. Our case report suggests that vaping can induce an inflammatory reaction mimicking metastatic cancer.

In-hospital cardiac arrest carries a poor prognosis. Registries of in-hospital cardiac arrest provide the opportunity to improve quality of care and conduct research of disease mechanisms and treatment. This paper describes the preliminary experience with systematic registration of in-hospital cardiac arrest at Aarhus University Hospital, Denmark. Data from 102 patients are presented and practical aspects and challenges of establishing a registry and implementing the collection of data in daily clinical practice are discussed.
