Cigarette Smoke Ups Mucus in Lungs - in Pulmonology, Smoking & Tobacco from MedPage Toda

Cigarette smoke suppresses a protein whose normal function is to prevent an overpopulation of mucus-producing cells in the lungs, researchers reported.

Suppression of the so-called Bik protein leads to hyperplasia of airway epithelial cells and mucous cell metaplasia, according to Yohannes Tesfaigzi, PhD, of the Lovelace Respiratory Research Institute in Albuquerque, N.M., and colleagues.

The finding could lead to treatments for chronic bronchitis, Tesfaigzi and colleagues reported online in the American Journal of Respiratory and Critical Care Medicine.

Over-secretion of mucus is a characteristic of chronic bronchitis, which affects many cigarette smokers and is associated with chronic obstructive pulmonary disease, Tesfaigzi and colleagues noted.

Normally, mucus secretion increases in the airway epithelium in response to bacteria or viral infectious agents and environmental pollutants. An inflammatory response kickstarts the proliferation of epithelial cells that produce the protective substance.

E-cigarettes are not safe, and here's why

E-cigarettes, or electronic cigarettes, have been largely unregulated, and there have been many doctors questioning its safety.

MedPage Today recently reported on the FDA’s analysis of such products, and now we have some guidance as to how dangerous they can be.

E-cigarettes are battery operated, and contain nicotine and other flavors that the user can inhale. Advertisements claim they are safer since they don’t burn tobacco.

But according to the FDA, they “contain carcinogens such as diethylene glycol — used in antifreeze — and nitrosamines.”

To his credit, internist Matthew Mintz has been sounding the alarm for awhile. Not only does he point out they are largely unregulated, there are real questions as to whether they help with smoking cessation at all. He writes that, “e-cigarettes were designed to be tobacco cigarette replacement products, not smoking cessation aides. It is also possible that smokers will use e-cigarettes in place of SOME of their tobacco cigarettes. Although this does decrease exposure to known dangerous products, e-cigarettes might therefore actually prolong tobacco cigarette smoking.”

It’s encouraging to see the FDA start critically analyzing the claims of these types of alternative products, often advertised on late-night television. Hopefully there will be more to come.

CDC - Seasonal Influenza (Flu) - Flu Information for Parents

Flu Information for Parents

Flu is more dangerous than the common cold for children. Each year, flu places a large burden on the health and well-being of children and families. An influenza vaccination is the best method for preventing flu and its potentially severe complications in children. CDC recommends that all children 6 months and older get a flu vaccine.

COPD (Chronic Obstructive Pulmonary Disease): MedlinePlus

MedlinePlus Trusted Health Information for You

COPD (Chronic Obstructive Pulmonary Disease)

 

Chronic Obstructive Pulmonary Disease (COPD) makes it hard for you to breathe. Coughing up mucus is often the first sign of COPD. Chronic bronchitis and emphysema are common COPDs.

Your airways branch out inside your lungs like an upside-down tree. At the end of each branch are small, balloon-like air sacs. In healthy people, both the airways and air sacs are springy and elastic. When you breathe in, each air sac fills with air like a small balloon. The balloon deflates when you exhale. In COPD, your airways and air sacs lose their shape and become floppy, like a stretched-out rubber band.

Cigarette smoking is the most common cause of COPD. Breathing in other kinds of irritants, like pollution, dust or chemicals, may also cause or contribute to COPD. Quitting smoking is the best way to avoid developing COPD.

Treatment can make you more comfortable, but there is no cure.

Bronchitis, Acute, Chronic, Respiratory, Pulmonary Conditions of the Lung, Legal Nursing Consultants, Medical/Legal Consulting

Bronchitis, Emedicine.com:"Acute bronchitis refers simply to inflammation of the tracheobronchial tree. The cause is usually infectious, but allergens and irritants can produce a similar clinical picture. Bronchitis typically occurs in the setting of an upper respiratory illness; thus, it is observed more frequently in the winter months. Asthma can be mistakenly diagnosed as acute bronchitis if the patient has no prior history of asthma. In one study, one third of patients who had been determined to have recurrent bouts of acute bronchitis were eventually identified as having asthma."

******************************************************

Bronchitis Overview, emedicinehealth.com:"Bronchitis is an acute inflammation of the air passages within the lungs. It occurs when the trachea (windpipe) and the large and small bronchi (airways) within the lungs become inflamed because of infection or other causes. The thin mucous lining of these airways can become irritated and swollen. The cells that make up this lining may leak fluids in response to the inflammation."
http://www.emedicinehealth.com/bronchitis/article_em.htm

******************************************************

Bronchitis, What Causes Bronchitis? The Nemours Foundation:"Acute bronchitis is usually caused by viruses, and it may occur together with or following a cold or other respiratory infection. Germs such as viruses can be spread from person to person by coughing. They can also be spread if you touch your mouth, nose, or eyes after coming into contact with respiratory fluids from an infected person. Smoking (even for a brief time) and being around tobacco smoke, chemical fumes, and other air pollutants for long periods of time puts a person at risk for developing chronic bronchitis."
http://www.kidshealth.com/teen/infections/common/bronchitis.html

******************************************************

Bronchitis, Signs and symptoms, mayoclinic.com:"A cough that brings up yellowish-gray or green mucus (sputum) is one of the main signs of bronchitis. Mucus itself isn't abnormal — your airways normally produce up to several tablespoons of mucus secretions every day. But these secretions usually don't accumulate, because they're continuously cleared into your throat and swallowed with your saliva. When the main air passageways in your lungs (bronchial tubes) are inflamed, they often produce large amounts of discolored mucus that comes up when you cough. If this persists for more than three months, it is referred to as chronic bronchitis. Mucus that isn't white or clear usually means there's a secondary infection."

Nurses' Station:"The idea for the Nurses' Station Catalog was conceived in 1989. After searching the marketplace in response to customer inquiries, it became obvious that there were no catalogs of this type serving the nursing profession. To be sure, there were several catalogs offering nurse's uniforms and a smattering of professional items. But there weren't any catalogs at the time offering a range of gifts, clothing, professional items, name badges, shoes and scrubs for nurses. It took two years of hard work to gather samples and put a together a catalog of the most unique and high-quality items for nurses."
