(B) The same patient after bariatric surgery and weight loss of 65 kilograms, with the pressure curve after bariatric surgery.

Vena Cava Compression Syndrome in Obesity is Reversed by Bariatric Surgery

To the Editor: Obesity is a major public health problem, with a prevalence of 10% to 20% in Western Europe.1 It is a risk factor for arterial hypertension, atherosclerosis, and heart failure.2 In times of rising prevalence in obesity, bariatric surgery offers an effective way to achieve weight loss.2 The indication for bariatric surgery is provided by interdisciplinary […]

(A) Coronal computed tomography demonstrating extensive bilateral ground-glass opacification, most pronounced at the periphery, and anterior lobular septal thickening. (B) Effluent, initially noted to be milky, cleared with progressive saline infusions during lung lavage.

Severe Pulmonary Alveolar Proteinosis in a Young Adult

  Pulmonary alveolar proteinosis is a rare lung disorder characterized by abnormal accumulation of surfactant within alveoli. Clinical presentation is nonspecific, but associated with characteristic radiologic findings and unique management options. We highlight a case of severe pulmonary alveolar proteinosis requiring total lung lavage in a young healthy man. Case Report A 37-year-old man with […]

Spider graph to depict the effect size values on changes in health-related quality of life and its subscales and dyspnea scores from baseline to 1 year, according to percent-predicted VO2 peak <80% and >80% at 1 year. Concentric circles around the central target represent effect size in mean changes in scores from baseline to 1 year.4 Health-related quality of life and dyspnea scores improved more in patients with percent-predicted VO2 peak >80% at 1 year (distance between central point [0.0] and blue line) compared with patients with percent-predicted VO2 peak <80% at 1 year (distance between central point [0.0] and red line). PEmb-QoL = pulmonary embolism quality of life questionnaire; SF-36 = Short-Form Health Survey-36; SOBQ = University of California at San Diego Shortness of Breath Questionnaire.

Quality of Life, Dyspnea, and Functional Exercise Capacity Following a First Episode of Pulmonary Embolism

We aimed to evaluate health-related quality of life (QOL), dyspnea, and functional exercise capacity during the year following the diagnosis of a first episode of pulmonary embolism. Methods This was a prospective multicenter cohort study of 100 patients with acute pulmonary embolism recruited at 5 Canadian hospitals from 2010-2013. We measured the outcomes QOL (by […]

Cough Syncope

Although cough is a common clinical symptom, the vasomotor effects on the heart and systemic circulation are often underappreciated. A healthy 42-year-old man without significant medical history presented with repetitive episodes of syncope during coughing. His examination, electrocardiogram, laboratory studies, and echocardiography results were normal, and carotid massage did not provoke any adverse response. During […]

Chest x-ray study showing right pneumothorax (green arrow) approximately 0.5 cm wide extending from the apex to the third intercostal space and presence of pneumomediastinum (black arrow).

Recurrent Pneumothoraces: Making the Link to Catamenial Pneumothorax

A 44-year-old woman with history of endometriosis on ovulatory suppressant therapy and right spontaneous pneumothorax treated with tube thoracostomy 2 months prior, presented with dyspnea and pleuritic chest pain. Physical examination was remarkable for decreased breath sounds and hyperresonance over the right hemithorax. Her labs were unremarkable. Chest radiography revealed a right pneumothorax (Figure 1). Her […]

Inferior vena cava respirophasic diameter variations between expiration (1:1.6 cm) and inspiration (2:1.2 cm). The top 2-dimensional image shows the correct ultrasound plane approximately 2 cm distal to the inferior cavo-atrial junction for M-mode measurements shown below.

Tele-Ultrasound to Guide Management of a Patient with Circulatory Shock

A 65-year-old man with a medical history of chronic obstructive pulmonary disease and ethanol abuse presented to the emergency department with tachypnea, tachycardia, and an altered mental status. He was hypotensive at 90/60 mm Hg. Examination of the patient showed confusion and decreased left-sided breath sounds. The serum laboratory values were significant for a urea […]
