An 80-year-old-woman was referred for evaluation of chest pain that appeared after providing care at home for her sick husband, which included helping him to get up and move about. The pain was initially triggered by lifting heavy objects but then became constant, without exacerbating or relieving factors. The pain was located in the left hemithorax and was not associated with shortness of breath or cough. Because the patient did not feel any better after a month, her general practitioner ordered a radiograph, which revealed a suspicious pulmonary nodule in the left upper lobe. She was a lifelong nonsmoker and denied any drug abuse. She had not been professionally exposed to lung carcinogens. She had a medical history of type 2 diabetes, ischemic cardiomyopathy, and renal artery stenosis. Her father died of lung cancer. She resided in Lille, France, and did not report any recent travel. A 78-year-old Chinese man presented in March 2019 with a 2-day history of small-volume hemoptysis. He did not report any associated chronic cough, sputum production, epistaxis, night sweats, unintentional weight loss, or fever. He was an ex-smoker of 10 pack years. His medical history was significant for ischemic heart disease on aspirin, as well as hospitalizations in 2016 and 2017 for hemoptysis. The patient's evaluation for hemoptysis was only notable for a right middle lobe nodule on chest CT imaging and Klebsiella pneumoniae on sputum cultures, for which he was treated with antibiotics. A 62-year-old woman with a history of partially treated Graves disease and hypertension presented with approximately 3 weeks of worsening fatigue, lower extremity myalgias, and shortness of breath. Akt inhibitor Her medical history included a thyroid radiofrequency ablation several years earlier. Following the ablation, she was found to have some residual thyroid activity, negating the need for therapy. She was lost to follow-up after months of normal thyroid-stimulating hormone values. On this presentation, the patient was noted to be in atrial fibrillation with a rapid ventricular rate, and although she presented alert and oriented initially, she developed progressive inattentiveness and confusion while in the ED. The patient was transferred to the medical ICU for further management of her rapid heart rate and progressive delirium. A 46-year-old otherwise healthy woman visited the ED twice over a period of 4 days for chest discomfort, midback pain, and dyspnea. The pain was localized, constant, nonpleuritic in nature, moderate in severity, and was not relieved by over-the-counter medications. The use of e-cigarettes to deliver aerosolized nicotine has gained popularity in recent years. Numerous reports have cited the development of acute pulmonary disease linked to vaping nicotine as well as marijuana-based products. As cultural attitudes evolve and policies shift toward the legalization of marijuana, its use has become more prevalent. Given the increased prevalence of marijuana consumption and e-cigarette usage, better insight into its potential to cause lung toxicity is warranted. The clinical, radiographic, and histopathologic characteristics of lung injury associated with vaping, particularly with marijuana-based products, have yet to be well described in the literature. We present eight patients, most of whom were admitted recently to our institution with acute respiratory failure following vaping. The majority of patients were young, with a median age of 31.5 years (range, 24-62 years) and with no known underlying lung disease. This case series highlights common clinical findings as well as the varied radiographic and histopathologic features of acute respiratory failure associated with vaping predominantly marijuana-based products. As more cases of vaping-associated pulmonary injury unfold, data will be available to further characterize this emerging disease entity. Improved understanding of disease pathogenesis and its clinical course will help clinicians determine optimal management and follow-up strategies for this patient population. Bruxism is a heterogeneous condition related to various underlying mechanisms, including the presence of OSA. This case report illustrates that sleep mandibular movement monitoring and analysis could provide a useful opportunity for detection of both sleep bruxism and respiratory effort. The current case suggests that tracking of respiratory effort could enable evaluation of bruxism and its potential interactions. Successful treatment of sleep-related respiratory effort may lead to improved or resolution of bruxism in cases where such a causal relationship does exist. Placebo comparisons are increasingly being considered for randomised trials assessing the efficacy of surgical interventions. The aim of this Review is to provide a summary of knowledge on placebo controls in surgical trials. A placebo control is a complex type of comparison group in the surgical setting and, although powerful, presents many challenges. This Review outlines what a placebo control entails and present understanding of this tool in the context of surgery. We consider when placebo controls in surgery are acceptable (and when they are desirable) in terms of ethical arguments and regulatory requirements, how a placebo control should be designed, how to identify and mitigate risk for participants in these trials, and how such trials should be done and interpreted. Use of placebo controls is justified in randomised controlled trials of surgical interventions provided there is a strong scientific and ethical rationale. Surgical placebos might be most appropriate when there is poor evidence for the efficacy of the procedure and a justified concern that results of a trial would be associated with high risk of bias, particularly because of the placebo effect. Feasibility work is recommended to optimise the design and implementation of randomised controlled trials. This Review forms an outline for best practice and provides guidance, in the form of the Applying Surgical Placebo in Randomised Evaluations (known as ASPIRE) checklist, for those considering the use of a placebo control in a surgical randomised controlled trial.
