Asthma is a chronic lung disease characterized by inflammation of the airways, wheezing, shortness of breath, and coughing. It is caused by environmental triggers like dust, pollen, or viruses. Symptoms include coughing, wheezing, chest tightness, and shortness of breath. Asthma is diagnosed based on a patient's medical history and symptoms, and tests like spirometry. While there is no cure, treatment focuses on reducing inflammation and controlling symptoms using long-term control medications like inhaled corticosteroids and quick-relief medications for acute symptoms. The goal of treatment is to help patients live normal, active lives with minimal asthma symptoms or flare-ups.

Clinical manifestation
Diagnostic evaluation
Bronchoprovocation Testing: Testing that is done to identify inhaled allergens; mucous membranes are directly exposed to suspected allergen in increasing amounts. Skin Testing: Done to identify specific allergens. Exercise Challenges: Exercise is used to identify the occurrence of exercise-induced bronchospasm. Radio allergosorbent Test: Blood test used to identify a specific allergen. Chest Radiograph: May show hyper expansion of the airways.
Managemnet
Goal- Promote bronchodilationn Reduce inflammation Remove secretions Prevent ongoing symptoms Prevent asthma attack Maintain normal lung function Avoid triggers
Pharmacological therapy 1. Long term control medication- Inhaled corticosteroid Leukotriene modifiers Long acting beta agonist Methylxanthines Combine inhaler
2 Quick relief medication Short acting beta agonist Anticholinergic Oral or I/V corticosteroid
3 Bronchial thermoplasty- Form severe asthma that does not respond to medication
Non- pharmacological
Oxygen therapy Postural drainage & chest physiotherapy Coughing & deep breathing exercise Avoidance of allergen relaxation technique acupuncture
Prevention
Patients with recurrent asthma should undergo tests to identify the substances that precipitate the symptoms. Possible causes are dust, dust mites, roaches, certain types of cloth, pets, horses, detergents, soaps, certain foods, molds, and pol- lens. If the attacks are seasonal, pollens can be strongly sus- pected. Patients are instructed to avoid the causative agents whenever possible.
Complications Complications of asthma may include status asthmaticus, respiratory failure, pneumonia, and atelectasis. Airway obstruction, particularly during acute asthmatic episodes, often results in hypoxemia, requiring the administration of oxygen and the monitoring of pulse oximetry and arterial blood gases. Fluids are administered, because people with asthma are frequently dehydrated from diaphoresis and in- sensible fluid loss with hyperventilation.

Introduction
Many have been interested in Tom Selleck health. not only because of his enduring presence on screen but also because of the challenges. and lifestyle choices he has faced and made over the years. This article delves into the various aspects of Tom Selleck health. exploring his fitness regimen, diet, mental health. and the challenges he has encountered as he ages. We'll look at how he maintains his well-being. the health issues he has faced, and his approach to ageing .
Early Life and Career
Childhood and Athletic Beginnings
Tom Selleck was born on January 29, 1945, in Detroit, Michigan, and grew up in Sherman Oaks, California. From an early age, he was involved in sports, particularly basketball. which played a significant role in his physical development. His athletic pursuits continued into college. where he attended the University of Southern California (USC) on a basketball scholarship. This early involvement in sports laid a strong foundation for his physical health and disciplined lifestyle.
Transition to Acting
Selleck's transition from an athlete to an actor came with its physical demands. His first significant role in "Magnum P.I." required him to perform various stunts and maintain a fit appearance. This role, which he played from 1980 to 1988. necessitated a rigorous fitness routine to meet the show's demands. setting the stage for his long-term commitment to health and wellness.
Fitness Regimen
Workout Routine
Tom Selleck health and fitness regimen has evolved. adapting to his changing roles and age. During his "Magnum, P.I." days. Selleck's workouts were intense and focused on building and maintaining muscle mass. His routine included weightlifting, cardiovascular exercises. and specific training for the stunts he performed on the show.
Selleck adjusted his fitness routine as he aged to suit his body's needs. Today, his workouts focus on maintaining flexibility, strength, and cardiovascular health. He incorporates low-impact exercises such as swimming, walking, and light weightlifting. This balanced approach helps him stay fit without putting undue strain on his joints and muscles.
Importance of Flexibility and Mobility
In recent years, Selleck has emphasized the importance of flexibility and mobility in his fitness regimen. Understanding the natural decline in muscle mass and joint flexibility with age. he includes stretching and yoga in his routine. These practices help prevent injuries, improve posture, and maintain mobilit

RESULTS: Overall life span (LS) was 2252.1±1742.5 days and cumulative 5-year survival (5YS) reached 73.2%, 10 years – 64.8%, 20 years – 42.5%. 513 LCP lived more than 5 years (LS=3124.6±1525.6 days), 148 LCP – more than 10 years (LS=5054.4±1504.1 days).199 LCP died because of LC (LS=562.7±374.5 days). 5YS of LCP after bi/lobectomies was significantly superior in comparison with LCP after pneumonectomies (78.1% vs.63.7%, P=0.00001 by log-rank test). AT significantly improved 5YS (66.3% vs. 34.8%) (P=0.00000 by log-rank test) only for LCP with N1-2. Cox modeling displayed that 5YS of LCP significantly depended on: phase transition (PT) early-invasive LC in terms of synergetics, PT N0—N12, cell ratio factors (ratio between cancer cells- CC and blood cells subpopulations), G1-3, histology, glucose, AT, blood cell circuit, prothrombin index, heparin tolerance, recalcification time (P=0.000-0.038). Neural networks, genetic algorithm selection and bootstrap simulation revealed relationships between 5YS and PT early-invasive LC (rank=1), PT N0—N12 (rank=2), thrombocytes/CC (3), erythrocytes/CC (4), eosinophils/CC (5), healthy cells/CC (6), lymphocytes/CC (7), segmented neutrophils/CC (8), stick neutrophils/CC (9), monocytes/CC (10); leucocytes/CC (11). Correct prediction of 5YS was 100% by neural networks computing (area under ROC curve=1.0; error=0.0).
CONCLUSIONS: 5YS of LCP after radical procedures significantly depended on: 1) PT early-invasive cancer; 2) PT N0--N12; 3) cell ratio factors; 4) blood cell circuit; 5) biochemical factors; 6) hemostasis system; 7) AT; 8) LC characteristics; 9) LC cell dynamics; 10) surgery type: lobectomy/pneumonectomy; 11) anthropometric data. Optimal diagnosis and treatment strategies for LC are: 1) screening and early detection of LC; 2) availability of experienced thoracic surgeons because of complexity of radical procedures; 3) aggressive en block surgery and adequate lymph node dissection for completeness; 4) precise prediction; 5) adjuvant chemoimmunoradiotherapy for LCP with unfavorable prognosis.
3. DEFINATION
Asthma is a common chronic inflammatory disease of
the airways characterized by variable and recurring
symptoms, reversible airflow obstruction and
bronchospasms
7. HISTORY
Asthma had existed in Egyptian times ,or may be be
Old ancient asthma cure was to heat a mixture of herb
bricks and to breath in the fumes.
It also became common in China, a few hundred years
ago.
To cure Asthma in China they would have a herb
containing ephedrine which they would inhale
Ephedrine
It is used for temporary relief o
shortness of breath , chest tightn
and wheezing due to bronchial
8. EPIDIMOLOGY
As of 2011, 235–330 million people worldwide are affected by
asthma
Approximately 250,000-345,000 people die per year from the
disease.
Around 7.5 million Pakistani adults and 15 million children
suffer from asthma due to the increasing urban population,
enlarging intercity industries, air pollution and other
environmental factors. In pakistan due to asthma deteath rate
is 5.1%.
9. CAUSES
•Animals (pet hair or dander)
•Dust mites
•Certain medicines (aspirin and other NSAIDS)
•Changes in weather (most often cold weather)
•Chemicals in the air or in food
•Exercise
•Mold
•Pollen
•Respiratory infections, such as the common
cold
•Strong emotions (stress)
•Tobacco smoke
11. Child-Onset Asthma
Asthma that begins during childhood is called child-onset asthma. This type of
asthma happens because a child becomes sensitized to common allergens in the
environment - most likely due to genetic reasons. The child is atopic - a genetically
determined state of hypersensitivity to environmental allergens.
Adult-Onset Asthma
This term is used when a person develops asthma after reaching 20 years of age. Adult-
onset asthma affects women more than men, and it is also much less common than
child-onset asthma.
12. Exercise-Induced Asthma
If you cough, wheeze or feel out of breath during or after exercise, you could be
suffering from exercise-induced asthma. Obviously, your level of fitness is also a
factor - a person who is unfit and runs fast for ten minutes is going to be out of breath.
However, if your coughing, wheezing or panting does not make sense, this could be
an indication of exercise-induced asthma.
Cough-Induced Asthma
Cough-induced asthma is one of the most difficult asthmas to diagnose. The doctor
has to eliminate other possibilities, such as chronic bronchitis, post nasal drip due
to hay fever, or sinus disease. In this case the coughing can occur alone, without
other asthma-type symptoms being present. The coughing can happen at any time
of day or night. If it happens at night it can disrupt sleep.
13. Occupational Asthma
This type of asthma is triggered by something in the patient's place of work.
Factors such as chemicals, vapors, gases, smoke, dust, fumes, or other particles
can trigger asthma. It can also be caused by a virus (flu), molds, animal products,
pollen, humidity and temperature. Another trigger may be stress.
Nocturnal Asthma
Nocturnal asthma occurs between midnight and 8 AM. It is triggered by allergens in
the home such as dust and pet dander or is caused by sinus conditions. Nocturnal or
nighttime asthma may occur without any daytime symptoms recognized by the
patient. The patient may have wheezing or short breath when lying down and may not
notice these symptoms until awoken by them in the middle of the night - usually
between 2 and 4 AM.
14. Steroid-Resistant Asthma
Asthma is usually a steroid responsive disease. A few patients respond
poorly to these drugs, and others need such high doses to control the
disease that side-effects become a serious problem. The term steroid
resistant asthma is used for both groups. In some patients, factors may
be operating to make the asthma worse and, thus, to increase the
requirement for steroids
15. ASTHMA CLASSIFICATION
Asthma classification Signs and symptoms
Mild intermittent
Mild symptoms up to two
days a week and up to two
nights a month
Mild persistent
Symptoms more than twice
a week, but no more than
once in a single day
Moderate persistent
Symptoms once a day and
more than one night a
week
Severe persistent
Symptoms throughout the
day on most days and
frequently at night
20. Asthma is Incurable
Asthma is an incurable illness. However, with good treatment
and management there is no reason why a person with
asthma cannot live a normal and active life.
21. TREATMENT
Goals Of Treatment:
Control airway swelling
Stay away from substances that trigger your
symptoms
Help you to be able to do normal activities
without asthma symptoms
22. MEDICATIONS
There are two main groups of asthma medication
Long-Term Control Medicines
Quick-Relief Medicines
23. LONG TERM CONROLL MEDICINE
This medications make the airways less sensitive, reduce redness
and swelling and help to dry up mucuse.
oInhaled corticosteroids
oLeukotriene modifiers
oLong-actingbeta2-agonists
oTheophylline
24. Inhaled corticosteroids
Purpose: Control
Drug names:
Beclomethasone (Qvar®)
Budesonide (Pulmicort)
Inhaled corticosteroids are the most effective medications to reduce airway
inflammation and mucus production. The use of these medicines leads to better
asthma control with fewer symptoms and flare-ups and less of a need for
hospitalization
25.
26. Long-acting forms beta2-agonists
Purpose:
Control
Drug names:
Salmeterol (Serevent®)
Formoterol (Foradil®)
The long-acting forms of beta2-agonists are used for better control, not
for relief. These drugs take longer to work and the benefits last longer,
even up to 12 hours. Salmeterol (Serevent®) and formoterol (Foradil®)
are the only inhaled, long-acting beta2-agonists. They are used twice a
day to maintain the open airways for long-term control. This is especially
helpful overnight
27. Leukotriene modifiers
Purpose: Control
Drug names:
Zafirlukast (Accolate®)
Zileuton (Zyflo®)
Montelukast (Singulair®)
Forms: Leukotrienes are chemicals that occur naturally in our bodies and cause
tightening of airway muscles and production of mucus. Leukotriene modifier
medications work by blocking the actions of leukotrienes in the body. Studies are
showing that these medications are helpful in improving airflow and reducing
asthma symptoms.
28. Theophylline
Purpose:
Control
This medication is available only in the oral form. It is long-acting and prevents
asthma episodes. It is used in difficult-to-control or severe asthma. It must be
taken daily and doses cannot be missed
29. Quick-Relief Medicines
Relievers are fast acting medications that give quick relief of
asthma symptoms (wheeze, cough, shortness of breath).
Anticholinergics
Short-acting forms beta2-agonists
30. Anticholinergic drugs
Purpose:
Relief
There are two anticholinergic bronchodilators currently available—Ipratropium bromide
(Atrovent® HFA), which is available as a metered dose inhaler and nebulizer solution, and
tiotropium bromide (Spiriva®), which is a dry powder inhaler. Ipratropium is used 4 times
per day whereas tiotropium is used only once per day as its action lasts for 24 hours.
These are not quick relief medications but medications that can enhance the
bronchodilator effect for certain asthmatics with difficult-to-control symptoms
31. Short-acting forms beta2-agonists
Purpose:
Relief
Short-acting beta2-agonists are rescue medications that relieve symptoms very
quickly. They work within 20 minutes and last for 4 to 6 hours. They are the
medications to use 15 to 20 minutes before exercise to prevent exercise-induced
symptoms. The inhaled forms are the best for treating sudden and severe or new
asthma symptoms.
Drug names:
Albuterol (Ventolin)
Metaproterenol (Alupent®)
32. combination medications
There are some inhalers that contain a combination of two different medications. These
inhalers allow both medications to be delivered from one device, shortening treatment
times and decreasing the number of inhalers
Advair
A combination of fluticasone and salmeterol
Symbicort
A combination of budesonide and formoterol
33. Xolair
Xolair is an injectable biologic medication approved for treatment of chronic
allergic asthma .Xolair is an anti-IgE medication that binds to and blocks the
attachment of immunoglobulin E (IgE) to its receptor on the surface of immune
cells called mast cells and basophiles. Antibodies are proteins that protect the
body from foreign substances and they are major components of the immune
system. IgE is a type of antibody that binds to specific receptors in response to
foreign proteins such as bacteria and allergens. IgE activates immune cells
causing the release of histamine, a chemical which is responsible for symptoms of
asthma .Blocking the action of IgE means less histamine is released, reducing
symptoms of asthma and hives.
34. Bronchial Thermoplasty
In bronchial thermoplasty, a long, flexible tube called a bronchoscope is
passed through the nose or mouth and down into the lungs until it reaches
the airways. A special fine wire is then passed down through the
bronchoscope until the end touches the airways. Radio waves are then
used to heat up the wires touching the airways. This heats up the airway
lining in a very controlled manner to about 65 degrees Celsius and this heat
causes some of the muscle surrounding the airways to break up. This then
makes it more difficult for the muscles surrounding the airways to tighten.
The aim is to reduce asthma symptoms and the risk of asthma attacks.
35. A nebuliser is a machine that creates a mist of medicine, which is then breathed in
through a mask or mouthpiece. They are more commonly used to give high doses
of reliever medicine in an emergency situation,
Nebuliser
Spacers
A spacer is a large plastic or metal container, with a mouthpiece at one end and a
hole for the aerosol inhaler at the other.
Spacers are important because they help to deliver asthma medicine to your lungs.
They also make your inhaler easier to use and reduce the risk of side effects.
Inhalers
Asthma inhalers are the most common and effective way to deliver asthma
drugs to the lungs. They are available in different types that require different
techniques for use. Some inhalers deliver one medication and others contain
two different medications
36.
37. SIDE EFFECTS OF CORTICOSTEROIDS
Common symptoms include:
sore throat
hoarse voice and/or
oral thrush
skin bruising
cataracts
glaucoma
adrenal suppression
growth suppression and/or
osteoporosis
38. SIDE EFFECTS OF LEUKOTRINE
MODIFIERS
Side effects are uncommon, but may
include
Muscle or joint pain,
Gastrointestinal disturbances,
Headache
Mood changes.
39. Side Effects of Short-acting beta-agonists
Possible side effects include:
Increased heart rate
Muscle tremor (shaking, especially in the hands)
Slight feelings of anxiety or nervousness
40. Side effects of Anticholinergics
Possible side effects include:
Dry mouth
Throat irritation
Agitation if taken in excessive doses
Glaucoma
41. PREVENTION
Learn about your asthma and ways to control it.
Follow your written asthma action plan.
Use medicines as your doctor prescribes.
Identify and try to avoid things that make your asthma
worse (asthma triggers). However, one trigger you
should not avoid is physical activity. Physical activity is
an important part of a healthy lifestyle. Talk with your
doctor about medicines that can help you stay active.
Keep track of your asthma symptoms and level of
control.
Get regular checkups for your asthma.
