Bronchial asthma in children is a chronic inflammatory disorder of the airways. It is characterized by recurrent episodes of wheezing, breathlessness, chest tightness and coughing, particularly at night or in the early morning. These episodes are usually associated with reversible airflow obstruction. The document discusses the pathogenesis, diagnosis and treatment of bronchial asthma in children. It outlines the goal of treatment as achieving and maintaining clinical control by preventing acute symptoms and disease recurrence while avoiding side effects. Treatment follows a step approach of increasing medication according to asthma severity.
An old presentation that I made when I was an Intern in Pediatric department.
The presentation contains 71 slides. It discusses bronchial asthma in pediatric age group starting from the definition of bronchial asthma and its pathophysiology and ending by the management of acute attacks of asthma and long-term management of bronchial asthma patients.

Asthma is a chronic respiratory condition characterized by inflammation and narrowing of the airways, leading to symptoms like wheezing, coughing, shortness of breath, and chest tightness. It can be triggered by various factors including allergens, respiratory infections, exercise, smoke, and pollutants. Management involves medication, identifying triggers, creating an action plan, monitoring symptoms, staying active, maintaining a healthy lifestyle, getting vaccinated, and regular check-ups with healthcare providers. Effective management aims to control symptoms, prevent flare-ups, and improve overall quality of life.

Operation “Blue Star” is the only event in the history of Independent India where the state went into war with its own people. Even after about 40 years it is not clear if it was culmination of states anger over people of the region, a political game of power or start of dictatorial chapter in the democratic setup.
The people of Punjab felt alienated from main stream due to denial of their just demands during a long democratic struggle since independence. As it happen all over the word, it led to militant struggle with great loss of lives of military, police and civilian personnel. Killing of Indira Gandhi and massacre of innocent Sikhs in Delhi and other India cities was also associated with this movement.
2024.06.01 Introducing a competency framework for languag learning materials ...Sandy Millin
http://sandymillin.wordpress.com/iateflwebinar2024
Published classroom materials form the basis of syllabuses, drive teacher professional development, and have a potentially huge influence on learners, teachers and education systems. All teachers also create their own materials, whether a few sentences on a blackboard, a highly-structured fully-realised online course, or anything in between. Despite this, the knowledge and skills needed to create effective language learning materials are rarely part of teacher training, and are mostly learnt by trial and error.
Knowledge and skills frameworks, generally called competency frameworks, for ELT teachers, trainers and managers have existed for a few years now. However, until I created one for my MA dissertation, there wasn’t one drawing together what we need to know and do to be able to effectively produce language learning materials.
This webinar will introduce you to my framework, highlighting the key competencies I identified from my research. It will also show how anybody involved in language teaching (any language, not just English!), teacher training, managing schools or developing language learning materials can benefit from using the framework.

3. What do we know about asthma?
Bronchial asthma is a chronic inflammatory disorder of the airways in
which many cells and cellular elements play role. The chronic
inflammation is associated with airway hyperesponsiveness that leads to
reccurrent episodes of wheezing, breathlessness, chest tightness and
coughing, particularly at night or in the early morning. These episodes are
usually associated with widespread but variable airflow obstruction within
the lung that is often reversible either spontaneously or with treatment.

9. Extrinsic asthma
The asthma episode is typically initiated by the
type1hypersensitivity reaction induced by exposure to the
extrinsic antigen.
Three types of extrinsic asthma are recognized
1.Atopic asthma
2.Occupational asthma(many forms)
3.Allergic bronchopulmonary aspergillosis (bronchial
colonization with aspergillus organisms followed by
development of IgE antibodies)
Atopic asthma is the most common type of asthma. Its onset
is usually in the 1st
two decades of life and is commonly
associated with other allergic manifestation in the patient as
well as in other family members.
Serum IgE levels are usually elevated as is the blood
eosinophils count.this forms of asthma is believed to be
driven by cd4+Tcells.
10. Intrinsic asthma
The triggering mechanisms are non-immune in
this form a number of stimuli that have little or no
effect in normal subjects can trigger broncho-
spasm. Such factors include aspirin, pulmonary
infections, especially those caused by virus
(RSV) ,cold, psychological stress, exercise and
inhaled irritatants such as ozone and sulfur
dioxide. there is usually no personal or family
history of allergic manifestation and serum IgE
levels are normal. These patients are said to
have an asthmatic diathesis.
11. Drug induced asthma
Is seen most commonly with
1.NSAID’S (COX-1 inhibitors)
2.Aspirin, Ibuprofen
3.Propranolol (because non selective Beta blockers)
• hypertrophic obstructive cardiomyopathy
• migrain
4.Timolol (eye drops, used to lower internal eye pressure in patient with
glaucoma)
Propranolol blocks the action of epinephrinic and norepinephrine on
both B1 and B2 adrenergic receptors.
Cox-1 inhibitors converts arachidonic acid to PG resulting in pain and
inflammation.
So In the case of joint pain +asthmatic condition we can use Cox-2.
•COX-2

20. Clinics of asthma exacerbation
• cough
• typical attacks of chest tightness, exhalative dyspnea, wheezing,
dry cough, viscous sputum
• Percussion findings are
• hyperresonance, tympanic sound due to emphesema
• Ausculatation:
• -rough respirative sounds, different rales like dry,
whistling, moist bubbling usually bilateral different in
quantity
• Can be accompanied by
• -Hypoxia and hypercapnia signs like- cyanosis
• - cardiovascular abnormalities ( tachycardia, murmurs,
rhythm abnormalities).

the bronchial
mucosa of a
patient with
asthma (60% in
pediatric
asthma.)
24. Skin allergy test: (prick test)
• Is a method for medical diagnosis of allergies that
attempts to provoke a small controlled allergic response.
• In the prick test ,a few drops of the purifired allergen are
gently pricked on to the skin surface usually the forearm.
• This test is usually done in order to identify allergies to
pet dender ,dust, polleen,food or dust mites.
• Intradermal injection are done by injecting a small amount
of allergen just beneath the skin surface.
• The testis also done to assess allergies to drug like
penicillin or bee venom.
• If an immune-response is seen in the form of a rash
urticaria or anaphylaxis it can be concluded that the
patient has a hypersensitivity (or allergy) to the allergen.
26. It is very important that the subject should stay in the
observation of physician for at least an hour or two the
subject may develop some signs and symptoms like:
low grade fever
Light headedness or dizziness
Wheezing or shortness of breath
Extensive skin rash
Swelling of face ,lips, mouth
Difficalties swallowing or speaking
For emergency condition the medications used are
Histamine antagonists
Epinephrine
Glucocorticoids
The skin rash or hives maybe itchy and best treated by
applying over the counter hydrocortisone cream.
28. Pulmonary function test are carried out mostly by using spirometer
The air in the lungs is classified in to 2 divisions
1. lung volumes 2.lung capacities

Editor's Notes
Bronchial asthma is chronic respiratory tract inflammatory disease with plenty cells and cell elements participation . Chronic inflammation cause concomitant respiratory tract hyperreactivity. It invokes recurrent episodes of wheezing, dyspnea, tightness in chest especially in night and morning time. These episodes usually are due to total but different in severity bronchial obstruction, that is reversible spontaneously or after the treatment ( Asthma definition from Asthma management protocol GINA 2003)
Occurrence of BA in Europe is twice more if we compare it in early 80-th
Occurrence of BA in children of Ukraine increased 1,6 times more for last decade
According to European Allergy Association occurrence of BA among children in various European countries ranges from 5 to 22%
Children from urbanized regions has BA more frequently
Predisposed factors
Hereditary inclination for atopic and allergic reactions
Bronchial hyperreactivity – is inhanced answer of bronchial tree for specific and nonspecific stimuli
Atopy – is hyperproduction of IgE
Sensibilization factors
Domestic: home and library dust, products of dust mites vital function, cockroaches, fish fodder, feather of pillows
Nonpathogenic fungus (musty, yeasty)
Epidermal allergens ( cat’s, dog’s)
Vegetable allergens ( trees’, weed, flowers’ pollens)
Prematurity play significant role due to immaturity of lung tissue and immune system
Mites, stock mites
Resolution factors ( triggers)
Pollutants – compounds of serum, nitrogen, nickel, CO – result of industrial plants, car exhaust gases
Smoking – active and passive
ARVD

Domestic, vegetative and other allergens
Physical loadings
Stress
Meteorological factors
Allergen – fixation on basophils, eosinophils and thrombocytes – cells activation – arachidonic acid hyperproduction
Cells activation – Releasing of preforming mediators (Pg, TX, PAF, LT)
Bronchial asthma pathogenesis
Late phase ( pathophisiologic stage)
Releasing of preforming mediators (PG, Tx, PAF, LT) – chemotaxis into inflammatory focus of eosinophils, neutrophils, thrombocytes – releasing of scondary mediators (Pg,, TX, PAF, HETE, LT, LX) – Contractility and prolifiration of smooth muscles
Bronchoobstructive syndrome - Microvasculature impairment - Bronchospasm and hyperreactivity of bronchi
Clinical stage of allergic reaction ( anaphylactic shock, BA attack, rhinoconjunctivitis syndrome, Quinck edema, urticaria)
