Cover Article Major Changes Made
to ACLS Guidelines
Major changes have been made
to the recommendations for advanced cardiac life support. One important change:
Practitioners must now confirm tube position by using both primary (clinical examination)
and secondary (technologic) methods of confirmation.
Cover Article Air Pollution
Is Lower, but More Progress Is Needed
There's good news about air
pollution: It has substantially decreased over the past few decades. The bad news
is that levels of invisible air pollutants, especially ozone, are still unacceptably
high in many urban areas and have become quite bad even in regions without a reputation
for air pollution.
Cover Article New CDC Recommendations
for Managing Pneumonia
Increasing rates of pneumococcal
resistance pose a challenge for physicians who treat patients with community-acquired
pneumonia (CAP). How is resistance defined in patients with CAP? What are the
best empiric antimicrobial regimens for the treatment of outpatients and hospitalized
patients with CAP? To address these and other questions, the CDC has issued new
recommendations for the management of CAP.
Cover Article Sleep Apnea
and Hypertension: New Support for a Link
Snoring has been linked to
hypertension in several small studies, but it has not been clear whether the association
is causal or coincidental. Two new studies indicate that sleep apnea is an independent
predictor of systemic hypertension in middle-aged and older persons.
Cover Article Airway pH Plays
Unsuspected Role in Asthma Physiology
In patients with asthma, the
pH of airway vapor condensate is substantially lower than normal. This airway
acidity appears to accelerate human eosinophil necrosis and to cause the conversion
of endogenous nitrite to nitric oxide. But why does this occur, and what implications
does it have for the treatment of asthma?

Care: What Is the Physician's Role?
Report Provides Core Principles for Providing Palliative
Care for the dying has long been inadequate. However,
a new set of 11 core principles, adopted by a number of major medical
organizations, can help physicians ensure that they deliver quality
care to dying patients.
Cover Article The
Air in There: Targeting Indoor Asthma Triggers
A new analysis on the pathogenetic role of various
indoor substances has identified only one substance--the lowly dust
mite--as the household allergen clearly capable of causing a first episode
of asthma in those who are genetically at risk. However, a number of
other agents can cause an asthma attack in persons who already have
the disease. This article provides a report card on putative asthma
Cover Article Lung
Disease Increases Osteoporosis Risk in Men
The risk of osteoporosis is markedly higher in
men with chronic lung disease than in men without such disease, and
corticosteroid use is not the only culprit--lung disease itself appears
to confer a marked increase in risk.
Cover Article Fungal
Sinusitis Treatment: A Life-Long Commitment
Physicians can expect to spend a lot of time with
any patient who develops fungal sinusitis. "When I take on a fungal
suniusitis patient, I expect to be married to that patient for the rest
of my professional life," said Frederick Kuhn, MD.
Cover Article Cellular
Memory Links Asthma and Allergy
Early immune responses to allergens may determine who develops
allergies or asthma later in life. In fact, new evidence suggests that
these two diseases may be even more closely related than has been thought.
Cover Article Asthma Is Misdiagnosed and Undertreated in the Elderly
A study done by the Cardiovascular Health Study Research Group indicated that
asthma diagnosis and treatment in elderly patients are clearly less than adequate.
Data showed that only 50% of these patients are being diagnosed properly and only
30% of diagnosed patients are being treated properly.
