Asthma

PITTSBURGH -- There is strong evidence suggesting -- but not proving -- the existence of a causal link between psychological stress and chronic conditions such as depression, cardiovascular disease, and HIV/AIDS, asserted researchers here.

COPENHAGEN -- If bacteria colonize the throat of a one-month-old infant, the risk of later persistent wheezing and asthma is sharply increased, researchers here found.

NEUHERBERG, Germany -- Babies taken swimming in public pools in the first year of life have an increased risk of diarrhea, researchers here said.

SAN DIEGO -- Eradication of Helicobacter pylori may have had the unintended consequence of unleashing an asthma threat even as the risk of gastric ulcer and cancer declined, results of a study reported here suggest.

ATLANTA -- Influenza vaccination rates have not rebounded after widespread vaccine shortages in the 2004-2005 flu season, CDC investigators said.

ANN ARBOR, Mich. -- Differences in self-management and socioeconomic factors account only in part for the disparities in glycemic control and asthma outcomes between minority and white patients with diabetes and asthma, investigators in two studies found.

NEW YORK -- Inpatients cared for by full-time hospitalists were likely to be discharged almost a day sooner than those in the care of nonhospitalists, but there was no significant difference in readmission rates or mortality, researchers found.

BRUSSELS, Belgium -- New guidelines offer a more conservative -- and pricey -- take on formula choices for infants who have an allergy to cow's milk.

ROCKVILLE, Md. -- The FDA has expanded the indications for FluMist, a nasal influenza vaccine, to include children ages two to five.

ULM, Germany -- Childhood asthma symptoms are more likely to be allergy related in affluent countries than in less developed ones, researchers found.

GENEVA, Switzerland -- No individual chronic disease - not angina, not arthritis, not asthma, not diabetes -- is more disabling than depression, according to a World Health Organization study.

COLUMBUS, Ohio -- Nearly 40% of varsity athletes may be susceptible to exercise-induced bronchospasm, researchers here said.

A 43-year-old woman presented to the emergency department with complaints of severe dyspnea, wheezing, and cough productive of white sputum. She had received a diagnosis of asthma 3 years earlier, based on symptoms of wheezing and cough. Since then, her drug regimen has included intermittent use of albuterol.

**One of the most common illnesses in general pediatrics is asthma--often in children who have not yet entered their teen years. While we ask the parents what symptoms they have noticed in their child, we do not always ask younger children directly. How reliable are their answers?

abstract: Common causes of poorly controlled asthma include nonadherence to long-term inhaler therapy; environmental exposures; and uncontrolled comorbidities, such as allergic rhinitis. Adherence can be limited by many factors, including inadequate patient education, medication cost, prior failed treatment, poor physician-patient relationship, unrealistic expectations for therapy, and depression. For patients who have a poor perception of their symptoms, emphasizing the "disconnect" between symptoms and pulmonary function can help motivate them to monitor themselves with a peak flow meter and to adjust their medication accordingly. For patients with allergic triggers, instituting allergen-specific environmental controls can decrease symptoms and urgent care visits for asthma. Chronic rhinosinusitis and gastroesophageal reflux disease can also contribute to difficult-to-control asthma, and treatment of these comorbidities can help reduce asthma symptoms.

BETHESDA, Md. -- Emphasizing that asthma affects different patients in different ways, the National Asthma Education and Prevention Program has issued new evidence-based guidelines on the disease.

COLUMBUS, Ohio -- Spirometry can help emergency departments distinguish between the wheezing of acute asthma in adolescents and vocal cord dysfunction, found investigators here.

LOS ANGELES -- Traffic-related air pollution increases asthma risk among children with genetic variants that affect the lungs' ability to clear toxins, researchers found.

BARCELONA, Spain -- Nurses develop occupational asthma at a rate that is more than double that of the general population, investigators in a multinational study have found.

SALT LAKE CITY -- Corticosteroids appear to be ineffective against first episode bronchiolitis in infants, despite frequent emergency room use, researchers said.

CHICAGO -- Medicare patients who couldn't read a physician's instructions, or who didn't understand what they read had a higher mortality rate than patients with adequate reading skills.

BOSTON -- A lack of fruit and fish in teenagers' diets may keep them from attaining full lung capacity and set them up for later respiratory problems, researchers here said.
