A 40-year-old woman (a nonsmoker) with history of idiopathic thrombocytopenic purpura and a platelet count > 90,000 cells/μL without specific medication was referred to pulmonary clinic for evaluation of multiple pulmonary nodules. The patient presented to an outside hospital with fatigue, lack of energy, and dyspnea on exertion for 2 years. She denied fever, cough, chest pain, or weight loss. An initial chest radiograph showed bilateral multiple pulmonary nodules. A chest CT scan revealed multiple nodular lesions, varying in size, in all lobes of both lungs. There was no mediastinal lymphadenopathy or pleural effusion. There was no significant hypermetabolic activity on a subsequent fluorodeoxyglucose PET scan/CT scan, and there had been no significant change. She underwent CT scan-guided percutaneous transthoracic biopsy and bronchoscopy with transbronchial biopsies, all of which were inconclusive. An open lung biopsy was considered.

Malignant pleural effusions cause significant morbidity, but there is no gold standard minimally invasive treatment. A new therapeutic approach combines talc pleurodesis and indwelling pleural catheters (IPCs) to enable outpatient management. This case series summarizes the safety and efficacy data of all patients (24) with a symptomatic malignant pleural effusion who underwent talc pleurodeses via IPCs between December 2010 and July 2013. Successful pleurodesis was achieved in 22 procedures (92%). There was one empyema, one hydropneumothorax, one recurrent effusion, and two minor complications: one drain site wound infection and one complaint of chest pain. Twenty-two procedures (92%) were performed in the outpatient setting. This report confirms the safety and efficacy of administering talc slurry through IPCs in an outpatient setting. Studies in a larger cohort are necessary to define the role of this novel approach in the treatment algorithm of patients with this condition.

Hypersensitivity pneumonitis (HP) is a diffuse granulomatous lung disease resulting from inhalation of an antigen to which an individual has been previously sensitized. Hot tub lung is an increasingly common form of HP associated with inhalation of water aerosols containing Mycobacterium avium complex organisms that contaminate hot tub water. Granulomatous lung disorders, most classically sarcoidosis, have been associated with unregulated 1-α-hydroxylase expression by macrophages present in the granulomas, causing conversion of 25-OH-vitamin D to the active form of vitamin D, 1,25(OH)2 vitamin D, and, thus, hypercalcemia. To our knowledge, this is the first confirmed case of hypercalcemia secondary to elevated 1,25(OH)2 vitamin D levels associated with HP.

Critical care practitioners must frequently make decisions about their patients' ability to swallow food, liquids, and pills. These decisions can be particularly difficult given the incompletely defined epidemiology, diagnostic criteria, and prognostic features of swallowing disorders in critically ill patients. Furthermore, the consequences of improper decisions-namely, aspiration, malnutrition, hunger, and thirst-can be devastating to patients and their families. This review outlines the problem of swallowing dysfunction in critically ill patients and then addresses the most clinically relevant questions that critical care practitioners face today. First, we review the epidemiology of swallowing dysfunction in critically ill patients. Next, we describe the different diagnostic tests for swallowing dysfunction and describe a general approach to the initial assessment for swallowing disorders. Finally, we explore the existing treatments for swallowing dysfunction. Given the burden of swallowing dysfunction in patients recovering from critical illness, enabling critical care practitioners to manage these disorders, while stimulating new investigation into their pathophysiology, diagnosis, and management, will enhance our care of critically ill patients.

Smoking and OSA are widely prevalent and are associated with significant morbidity and mortality. It has been hypothesized that each of these conditions adversely affects the other, leading to increased comorbidity while altering the efficacy of existing therapies. However, while the association between smoking and OSA is plausible, the evidence is less than conclusive. Cigarette smoking may increase the severity of OSA through alterations in sleep architecture, upper airway neuromuscular function, arousal mechanisms, and upper airway inflammation. Conversely, some evidence links untreated OSA with smoking addiction. Smoking cessation should improve OSA, but the evidence to support this is also limited. This article reviews the current evidence linking both conditions and the efficacy of various treatments. Limitations of the current evidence and areas in need of future investigation are also addressed.

Efforts to answer the question of whether or when physicians may unilaterally refuse to provide treatments they deem medically futile, but that are nonetheless demanded by patients or their surrogates, have been characterized as intractable failures. We propose a new look at this old problem and suggest reframing the debate in terms of the implicit social contract, in healthy democracies, between the medical profession and the society it serves. This ever-evolving contract is predicated upon providing patients with beneficial and desired medical care within the constraints of scarce resources and the characteristics of our health-care system. The contract ranges over a continuum of decisions, from those that do not need an explicit negotiated agreement with the patient or surrogate, to those that do. Between these two poles lies a contentious gray area, where the rights and obligations of patients and physicians are being shaped continuously by the many forces that are at play in a democratic society, including professional guidelines, social advocacy, legislation, and litigation. We provide examples of how this gray area has been and is negotiated around rights to refuse and demand a variety of life-sustaining treatments, and anticipate conflicts likely to arise in the future. Reframing the futility debate in this way reveals that the issue is not a story of intractable failure, but rather, a successful narrative about how democracies balance the legitimate perspectives of patients and physicians against a backdrop of societal constraints and values.
