Is asthma preventable?

In an individual who has been diagnosed with asthma, the focus of contemporary treatment emphasizes prevention of symptoms such as breathlessness, chest discomfort, cough, mucus production, and wheezing. Certain asthma medications, sometimes referred to as “controller medicine,” are designed and prescribed to maintain normal lung function, and to prevent an exacerbation of asthma — what used to be called an asthma “attack”. Identification of an individual’s asthma triggers and avoidance of exposure to the triggers are other ways to prevent an asthma exacerbation.

Human Cardiac Mast Cells and Their Role in Severe Allergic Reactions

Although great strides have been made in the treatment of bronchial asthma, asthma-associated mortality is increasing in many countries. The first record of asthma dates back 30 centuries, but it is only during recent decades that systematic attempts have been made to understand the pathophysiology of this condition and to treat the disorder. At the beginning of this century, William Osier reported that acute attacks of bronchial asthma never result in death.

T Lymphocytes in Chronic Asthma

Up to the mid-1980s there was a fairly general consensus that the mast cell was central in the pathophysiology of asthma. In 1983 on the occasion of the Third International Symposium on Asthma, it was suggested that ‘perhaps asthma is no more than physical allergy of the mast cells of the lung’, the analogy being made with urticaria where it was established that allergic and non-allergic triggers could release histamine (and presumably other mediators) from mast cells, which in turn produced the urticarial lesion. Thus asthma, which was characterized clinically as intermittent airway narrowing, was believed to result, in atopic asthma, from intermittent type I (immediate-type hypersensitivity) reactions by IgE-dependent mast cell mediator release or by mast cell degranulation owing to physical or other stimuli in non-atopic (‘intrinsic’) asthma.

What is the contemporary view of asthma, and how does it differ from traditional views?

For many years, asthma was viewed as a disease of airway narrowing, or bronchoconstriction. In the traditional view, the bronchial passages, especially those encircled by specialized muscle fibers, became narrowed or constricted, and an inevitable “attack” would follow.

Acute asthma during pregnancy. FAQ

Apart from possible adverse effects of medications, can acute asthma by itself be dangerous for the fetus? Acute asthma causes lack of oxygen in the mother’s blood, and thus the fetus also suffers from lack of oxygen, sometimes more than the mother. While the fetus can tolerate this lack for some time, the same kinds of damage can be done that a lack of oxygen can produce during delivery: varying degrees of brain damage.

Theox cr

Theox Cr is prescribed to treat rhythm disturbance of the heart, supraventricular tachycardia as well as to control heart rate response to other rhythm disturbances, specifically, atrial fibrillation and flutter. It may also be used for treatment of the acute attack or for chronic long-term treatment. The enteric-coated and extended-release dosage forms are usually used only for chronic treatment.

Acute Asthma Attacks. Part 2

In patients arriving at the emergency department (ED) with acute asthma attacks, the first step is to differentiate between an uncomplicated acute episode of short duration and a prolonged acute episode, especially if the patient is steroid-dependent. Determine whether superimposed infection exists (viral or bacterial); the most recent National Asthma Guidelines reaffirm that antibiotics should not be used to treat acute asthma attacks except when a bacterial infection, due to another condition such as pneumonia or sinusitis, is present. If an antibiotic needs to be prescribed for asthma and chronic bronchitis patients, amoxycillin, augmentin, bactrim DS, biaxin, or vibramycin are good choices.

Acute Asthma Attacks

Acute symptoms of asthma are one of the most common acute illnesses primary care physicians are called upon to manage, either in the office or, often, at night in the emergency department (ED). Acute attacks are increasing, particularly in children, and these attacks often require aggressive emergency treatment. The symptoms can range from persistent coughing to the full-blown manifestations of respiratory failure.

Dietary Magnesium and Asthma

Magnesium is fourth on the list of the most abundant cations in the body (following calcium, sodium, and potassium), and it is second only to potassium as the most abundant intracellular cation. It is an essential cofactor in more than 300 different enzymatic reactions, including carbohydrate utilization, ATP metabolism, muscle contraction, transmembrane ion transport (calcium, sodium, chloride, potassium), and the synthesis of fat, protein, and nucleic acids. Magnesium also appears to play an important role in lung function.
