Prospective studies on the incidence of VTE during severe sepsis and septic shock remain absent, hindering efficacy assessments regarding VTE prevention strategies in sepsis. ⋯ To our knowledge this is the first multicenter prospective study to identify a high incidence of VTE in patients with severe sepsis and septic shock, despite the use of universal, guideline-recommended thromboprophylaxis. Our findings suggest that the systemic inflammatory milieu of sepsis may uniquely predispose patients with sepsis to VTE. More effective VTE prevention strategies are necessary in patients with sepsis.

The Chiari 1 malformation is characterized by > 5-mm herniation of the cerebellar tonsils through the foramen magnum. Consequent compression of the brain stem and nearby neuronal structures involved in respiratory control and maintenance of pharyngeal wall muscle tone may result in respiratory changes during sleep. ⋯ Although data have accrued on the significance of sleep-related breathing disorders in patients with the Chiari 1 malformation, many management questions remain unanswered. This article reviews the available literature on prevalence and management of sleep-related breathing disorders in patients with the Chiari 1 malformation.

Mortality risk prediction tools have been developed in idiopathic pulmonary fibrosis, however, it is unknown whether these models accurately estimate mortality in systemic sclerosis-associated interstitial lung disease (SSc-ILD). ⋯ The modified du Bois index has good discrimination and calibration for the prediction of 1-year mortality in SSc-ILD. FVC and 6-min walk distance are important independent predictors of 1-year mortality in SSc-ILD.

A 66-year-old male nonsmoker from Arizona was referred to our practice for evaluation of chronic cough. He had a history of biopsy-proven relapsing polychondritis manifesting as right auricular and nasal pain and swelling 9 months prior to presentation. The onset of his cough coincided with the diagnosis of relapsing polychondritis, and he was prescribed prednisone 90 mg/d, which promptly relieved his rheumatologic and respiratory symptoms. ⋯ A second chest radiograph done 6 months before presentation, while the patient was receiving prednisone 20 mg/d, was normal as well. In anticipation of our evaluation, he stopped all glucocorticoids for 7 days. He was not receiving any other medications, and he had no history of an atopic diathesis.
