Although there may be many factors triggering asthma flares, seven of them seem to be the most common and deserve closer attention. We shall try to eliminate all of them concurrently if we want to reach satisfactory temporary and long term results. The 7 triggers of asthma symptoms are:

Children aged <5 years or with certain chronic medical conditions are at increased risk for complications and death from influenza (1--3). Because of this increased risk, the Advisory Committee on Immunization Practices (ACIP) has prioritized influenza prevention and treatment for children aged <5 years and for those with certain chronic medical and immunosuppressive conditions (4,5). CDC monitors child influenza deaths through its influenza-associated pediatric mortality reporting system. As of August 8, 2009, CDC had received reports of 477 deaths associated with 2009 pandemic influenza A (H1N1) in the United States, including 36 deaths among children aged <18 years. To characterize these cases, CDC analyzed data from April to August 2009. The results of that analysis indicated that, of 36 children who died, seven (19%) were aged <5 years, and 24 (67%) had one or more of the high-risk medical conditions. Twenty-two (92%) of the 24 children with high-risk medical conditions had neurodevelopmental conditions. Among 23 children with culture or pathology results reported, laboratory-confirmed bacterial coinfections were identified in 10 (43%), including all six children who 1) were aged ≥5 years, 2) had no recognized high-risk condition, and 3) had culture or pathology results reported. Early diagnosis of influenza can enable prompt initiation of antiviral therapy for children who are at greater risk or severely ill. Clinicians also should be aware of the potential for severe bacterial coinfections among children diagnosed with influenza and treat accordingly. All children aged ≥6 months and caregivers of children aged <6 months should receive influenza A (H1N1) 2009 monovalent vaccine when available (6).

In the southern hemisphere, most countries (represented by Chile, Argentina, New Zealand, and Australia) appear to have passed their peak of influenza activity and have either returned to baseline levels or are experiencing focal activity in later affected areas; while a few others (represented by South Africa and Bolivia) continue to experience high levels of influenza activity.

Many countries in tropical regions (represented by Central America and tropical regions of Asia), continue to see increasing or sustained high levels of influenza activity with some countries reporting moderate strains on the healthcare system. In temperate areas of the northern hemisphere (represented by North America, Europe, and Central Asia), influenza and respiratory disease activity remains low overall, with some countries experiencing localized outbreaks. In Japan, the level of influenza activity has passed the seasonal epidemic threshold, signaling a very early beginning to the annual influenza season.

According to their figures, it is responsible for approximately five million deaths worldwide every year.

Tobacco smoking is a known or probable cause of approximately 25 diseases, and even the WHO says that its impact on world health is not fully assessed.

Smoking damage

The components of cigarette smoke collectively explain its health impacts. Smoke contains over 4,000 chemicals. Nicotine is the predominant addictive chemical and the reason why smokers continue to smoke.

Heart attack and stroke

UK studies show that smokers in their 30s and 40s are five times more likely to have a heart attack than non-smokers.

Tobacco contributes to the hardening of the arteries, which can then become blocked and starve the heart of blood flow, causing the attack.

The Eating Disorders Association estimates that about 165,000 people in the UK have eating disorders with 10% dying as a result, but experts believe it could be higher.

Most sufferers are women, but one in 10 are now men.

The most common eating disorders are anorexia, bulimia and compulsive over-eating. But other disorders exist. For example, some people severely restrict the range of food they eat or several children have a psychological fear of food.

Anorexia, which involves depriving the body of food, is more common in young people. Children as young as three have been treated for it.

Bulimia, characterised by a cycle of starving and bingeing, is more likely in adults.

The emphasis on super-thin models has been blamed for the increase in eating disorders.

Experts say that these can have an effect on how people perceive themselves, but the causes of eating disorders are usually more complex and are linked to general feelings of self-worth.
