Pulmonology

In adults who present with persistent cough following an upper respiratory tract infection but who have no history of asthma or chronic obstructive pulmonary disease, lung findings are usually “normal” on auscultation.

Avoidance of guidelines because they are “cookbook” is no longer an adequate excuse-especially when we are doing things incorrectly and expensively, while adding to potential complications

A universal vaccine that protects against all strains of influenza virus may eventually replace yearly seasonal flu shots. This vaccine has been shown to be effective in animals, report investigators from the National Institute of Allergy and Infectious Diseases (NIAID).

Nitrofurantoin has been widely used for the treatment and prevention of recurrent urinary tract infections since its introduction into clinical practice in 1953. Although it continues to be an effective antibiotic, nitrofurantoin is associated with several adverse effects, including pulmonary toxicity.

Many pharmacological options exist for allergic rhinitis. Intranasal corticosteroids are the most effective medication class for patients with moderate to severe symptoms; those with milder intermittent symptoms can be treated with a second-generation oral or intranasal antihistamine.

Diabetes mellitus is a group of disorders characterized by hyperglycemia and the resulting macrovascular and microvascular complications.

H1N1 influenza has paid an unwelcome visit to a number of nursing homes, reports the CDC.

Malignant thymoma is an indolent tumor arising from the thymic epithelial cells located in the anterior mediastinum. These tumor cells spread via regional metastasis or invade surrounding structures, including the pleural space.

Endobronchial schwannomas are rare and often benign neoplasms that develop from the nerve sheath of the peripheral nervous system.

A 31-year-old Bangladeshi man presented with dull, aching abdominal pain primarily in the right flank. The pain began a week after he underwent exploratory laparotomy for a perforated duodenal ulcer. He had been taking oxycodone/acetaminophen, docusate sodium, and omeprazole since the surgery.

Although the prevalence of tuberculosis (TB) in the United States continues to decline (from 2006 to 2007, the total number of TB cases declined 4.2%, from 13,779 cases to 13,293), the rate of decline has slowed in recent years.1 The rate in foreignborn persons is much higher than in US-born persons and appears to be increasing.1

Both seasonal and H1N1 influenza pose a greater risk of severe illness and complications in patients with diabetes-and these infections can also wreak havoc with blood glucose levels.

Imaging experts are lining up to caution physicians not to read too much into study findings suggesting that chest CT is better than general radiography for examining A-H1N1 flu patients.

Lung disease was the most common underlying condition in a British study of 192 patients who had been admitted to the hospital because of complications related to H1N1 influenza.

Confirming the presence of the H1N1 influenza virus in patients with suspected infection is critical to public health efforts to track, study, and contain the disease-and to the ability of clinicians to provide optimal management. Appropriate diagnostic testing is key to this process.

Not all patients in whom infection with the H1N1 influenza virus is suspected or confirmed need to be treated. Many patients with mild disease can forgo pharmacotherapy. In fact, in many cases, it may even be prudent to discourage such patients from coming into their health care provider's office, in the interest of infection control. However, all patients with severe disease and those considered at high risk for complications from seasonal influenza should be offered therapy with antiviral agents.

Before considering the infection control strategies recommended during the current H1N1 influenza pandemic, it is useful to review the transmission characteristics of influenza viruses-including H1N1-that form the basis for these strategies:

The ability to recognize cases of the new H1N1 flu and distinguish these from seasonal influenza and other respiratory illnesses is perhaps the overriding concern of primary care practitioners. Prompt and accurate identification of this entity is the key to both effective management of individual illness and effective public health measures.

On Sept 15, 2009, the FDA approved 4 vaccines against the H1N1 influenza virus. Distribution of the vaccine to about 90,000 sites across the United States will begin in mid October.

When you encounter unexplained seizures or mental status changes in children who have influenza-like illness, send respiratory specimens for diagnostic testing and promptly start empirical antiviral therapy, especially in hospitalized patients.

Reserve antivirals for adults and children over age 1 who have severe novel H1N1 influenza or who are at high risk for complications.

Federal health officials stressed the need to start planning now for the fall influenza season when they met with state delegates at the H1N1 Influenza Preparedness Summit. "Over the course of coming weeks and months, we will move aggressively to prepare the nation for the possibility of a more severe outbreak of the H1N1 virus," said Secretary of Health and Human Services Kathleen Sebelius.

Chronic obstructive pulmonary disease (COPD) is recognized as a common condition in older adults, but asthma is often considered something that most patients outgrow long before they retire and qualify for Medicare.

More than 1 million persons in the United States may have been infected with novel H1N1 (swine) influenza virus, according to US health officials. In a recent media briefing, Dr Anne Schuchat, Director of the National Center for Immunization and Respiratory Diseases, CDC, noted that the infection is continuing to spread well past the typical influenza season in the Northern Hemisphere.
