Hair dye allergies are the last thing on your mind when you look in the mirror and see your first gray hair! If you're like most of us, you want to look great without a lot of expense or hassle. You'd think that most hair coloring products would be safe, since they are sitting right there on the drugstore shelf, promising gorgeous hair! Well, unfortunately for some people, the strong chemicals in many hair color products can cause an allergic reaction to hair dye. This could be as mild as some itching on your eyelids or on the top of your ears, or it could be more severe. A hair dye allergy doesn't always show up on the scalp, which has a thicker layer of protective skin than other parts of our body.
Nontuberculous mycobacteria (NTM) are environmental organisms found in both water and soil that can cause severe pulmonary (lung) disease in humans. Pulmonary NTM is on the rise in the United States, according to a large study of people hospitalized with the condition. A research team led by epidemiologists from the National Institute of Allergy and Infectious Diseases, part of the National Institutes of Health, analyzed hospital discharge records of patients in 11 states whose combined total population represents 42 percent of the country. They reviewed database records spanning 1998 to 2005, and identified more than 16, 475 hospitalizations associated with pulmonary NTM in people without AIDS.
Seasonal allergies caused by pollen and other allergens affect 40 million Americans and cost more than $1 billion in annual treatment costs. Manifestations of Seasonal Allergies Although it's usually not a dangerous condition, it can be very uncomfortable and, for some people, can severely interrupt daily activities. The standard reactions of seasonal allergies include sneezing, itchy throat, headache, swollen sinuses, runny nose, and itchy, watery eyes. Differentiate Seasonal Allergies From Common Cold Symptoms of seasonal allergies occur suddenly and continue as long as the person exposed to the allergen " cause of allergy". Fever is not usually present but sneezing is a prominent feature and more commonly associated with wheezing.
A recent commentary suggests that the U.S. should spend roughly $197 million more than it currently does to research the impact of climate change on public health. The analysis found that the U.S. spends about $3 million in federal funds on research related to the health impacts of climate change, says Marie S. O'Neill, one of the commentary co-authors. This isn't nearly enough to adequately address the public health issues related to global warming, the group concluded. The commentary's lead author was Kristie Ebi, a University of Michigan-trained epidemiologist and expert on climate change and public health, who is an adjunct professor of Environmental Health Sciences.
If you've ever suffered from airborne allergies, you're probably familiar with the symptoms: nasal congestion and pressure, watery and burning eyes, coughing and sneezing, and perhaps a sore throat. More severe symptoms include sinus headaches, neck pain or even upper tooth or jaw pain. An allergy attack can make life generally miserable, causing fatigue and even difficulty sleeping due to sinus congestion. Very simply, airborne allergy symptoms are the body's reaction to inhaled irritants. Your nasal sinuses are a series of bony cavities behind the nose that are lined with a soft, moist tissue called mucosa. Part of the job of the mucosa is to trap airborne particles you inhale, in order to prevent them from being breathed in to the lungs.
A study conducted in Vietnam has added further weight to the view that parasitic gut worms, such as hookworm, could help in the prevention and treatment of asthma and other allergies. Led by Dr Carsten Flohr, a Clinical Scientist from The University of Nottingham, and Dr Luc Nguyen Tuyen from the Khanh Hoa Provincial Health Service in central Vietnam, the study is the largest double-blind placebo controlled clinical trial to date looking at the potential links between hookworm and other gut worm infections and allergic conditions such as asthma and eczema. Thanks to improved hygiene practices parasitic worms have been mostly eradicated among human populations living in developed countries.
