ROCKVILLE, Md. -- Even carrying a few extra pounds in patients who are not frankly obese is enough to increase the risk of death, according to two large studies.

LEIDEN, The Netherlands -- Whether by road, rail, or air, travel for more than four hours caused a two-fold increase in the risk of deep-vein thrombosis, researchers here reported.

MINNEAPOLIS -- Teens with a poor body image tend to behave in ways that are self-perpetuating, researchers here said, and may react better to positive encouragement rather than to criticism.

BOSTON -- There are a lot more chubby babies than there used to be, reported investigators here. That goes for chubby preschoolers, too.

WASHINGTON -- The Physicians Committee for Responsible Medicine, a crusading group that has long ranked vegetarianism high on its agenda, has made a compelling case for a low-fat vegan diet to improve glycemic control.

ROYAL OAK, Mich. -- Morbidly obese patients with poor cardiorespiratory fitness are more likely to suffer major complications after bariatric surgery, according to researchers here.

WINSTON-SALEM, N.C. -- The waistline may succumb to a diet, but it takes exercise as well to shrink the size of subcutaneous abdominal fat cells that affect type 2 diabetes, according to researchers here.

STANFORD, Calif. -- Abnormal body-image concerns and the risk of a full-blown eating disorder in high-risk college-age women can be significantly reduced by an Internet-based behavioral intervention, researchers here reported.

LONDON -- For some patients with cardiovascular disease risk factors, the root cause may be the loneliness of childhood, according to a study that followed more than 1,000 adults from birth.

The authors present a case that demonstrates the diagnostic challenge of mediastinal tumors. They describe the clinical presentation of a patient who had a central endobronchial tumor that was identified as a primary mediastinal spindle cell neoplasm.

We describe a case in which a patient received thrombolytic therapy after he presented with a clinical picture consistent with submassive pulmonary embolism (PE). Two months later, a malignant peripheral nerve sheath tumor was diagnosed, and the patient died with metastatic disease. The filling defect in the left main pulmonary artery originally interpreted as PE was in fact a tumor. This case describes an unusual presentation of a rare disease (malignant peripheral nerve sheath tumor) mimicking a submassive PE.

Abstract: Tracheobronchomalacia is a form of expiratory central airway collapse characterized by softening of the airway wall cartilaginous structures. Symptoms often mimic asthma and chronic obstructive pulmonary disease. Pulmonary function test results may suggest a diagnosis, but findings are neither sensitive nor specific. Bronchoscopy and novel dynamic radiographic studies contribute to the diagnosis and help differentiate true malacia from other forms of expiratory central airway collapse. Treatment options include medication; noninvasive ventilatory support; interventional bronchoscopy with airway stent insertion; and open surgical procedures, such as tracheostomy, tracheal resection, and tracheoplasty.
