Hospital 'Handoffs' Common Source of Medical Errors
TUESDAY, Dec. 20 (HealthDay News) -- Poor communication during hospital "handoffs," when patient care transitions from one physician or team of physicians to the next, may be responsible for many of the estimated 44,000 to 98,000 deaths that occur each year in U.S. hospitals due to medical errors, according to a study published in the December issue of Academic Medicine.
Carbon Monoxide Relieves Chronic Colitis in Mice

Acute Respiratory Syndrome Lethal in Autoimmune Patients
FRIDAY, Dec. 16 (HealthDay News) -- Acute respiratory distress syndrome (ARDS) is a common event in patients with "catastrophic" antiphospholipid autoimmune disease, according to a report in the January issue of Annals of the Rheumatic Diseases. Patients with antiphospholipid disease who present with ARDS should be suspected of the catastrophic version of the disease, which is characterized by multiorgan failure due to small vessel occlusion.
Asthma Control Less Likely in Overweight Patients

High-Efficiency Vacuum Cleaners Don't Benefit Allergy
THURSDAY, Dec. 15 (HealthDay News) -- Although high-efficiency vacuum cleaners are often recommended for patients with allergies, the vacuums confer no benefit compared with regular models, according to a study published in the January issue of Allergy.

Wheat and Maize Allergies More Complex Than Expected
