The document discusses the approach to cough and its management. It defines cough and describes the cough reflex mechanism. Cough can be initiated voluntarily or involuntarily and involves both afferent and efferent pathways. Cough receptors are located in various areas including the pharynx, sinuses, stomach and ears. The cause of cough can be extra-pulmonary. A careful history regarding onset, character, production, timing and associated symptoms is important to narrow the diagnosis. Acute, recurrent and chronic cough have different etiologies depending on the patient's age. Proper diagnosis involves considering clinical features, sputum examination and treatment response.

Interstitial lung disease is a general category that includes many different lung conditions. All interstitial lung diseases affect the interstitium, a part of the lungs' anatomic structure.
Some of the types of interstitial lung disease include:
Interstitial pneumonia: Bacteria, viruses, or fungi may infect the interstitium of the lung. A bacterium called Mycoplasma pneumonia is the most common cause.
Idiopathic pulmonary fibrosis : A chronic, progressive form of fibrosis (scarring) of the interstitium. Its cause is unknown.
Nonspecific interstitial pneumonitis: Interstitial lung disease that's often present with autoimmune conditions (such as rheumatoid arthritis or scleroderma).
Apparently a lengthy presentation actually very good for junior physicians as it covers all aspects of assessment, diagnosis and treatment of pleural effusion

Embracing GenAI - A Strategic ImperativePeter Windle
Artificial Intelligence (AI) technologies such as Generative AI, Image Generators and Large Language Models have had a dramatic impact on teaching, learning and assessment over the past 18 months. The most immediate threat AI posed was to Academic Integrity with Higher Education Institutes (HEIs) focusing their efforts on combating the use of GenAI in assessment. Guidelines were developed for staff and students, policies put in place too. Innovative educators have forged paths in the use of Generative AI for teaching, learning and assessments leading to pockets of transformation springing up across HEIs, often with little or no top-down guidance, support or direction.
This Gasta posits a strategic approach to integrating AI into HEIs to prepare staff, students and the curriculum for an evolving world and workplace. We will highlight the advantages of working with these technologies beyond the realm of teaching, learning and assessment by considering prompt engineering skills, industry impact, curriculum changes, and the need for staff upskilling. In contrast, not engaging strategically with Generative AI poses risks, including falling behind peers, missed opportunities and failing to ensure our graduates remain employable. The rapid evolution of AI technologies necessitates a proactive and strategic approach if we are to remain relevant.

The French Revolution, which began in 1789, was a period of radical social and political upheaval in France. It marked the decline of absolute monarchies, the rise of secular and democratic republics, and the eventual rise of Napoleon Bonaparte. This revolutionary period is crucial in understanding the transition from feudalism to modernity in Europe.

2. Cough is an explosive
expiration that provides a
normal protective
mechanism for clearing
the tracheobronchial tree
of secretions and foreign
material.
DEFINITION
3. The bronchi and trachea
are so sensitive to light
touch that excessive
amounts of foreign
matter or other causes of
irritation initiates the
cough reflex.
4. Coughing may be initiated
either voluntarily or
reflexively
As a defensive reflex it has
both afferent and efferent
pathways
5. The afferent limb includes receptors
within the sensory distribution of the
trigeminal, glossopharyngeal,
superior laryngeal, and vagus nerves.
The efferent limb includes the
recurrent laryngeal nerve and the
spinal nerves.
6. COUGH RECEPTORS RECIDES IN
PHARYNX, PARANASAL SINUSES,
STOMACH AND EXTRA-AUDITORY
CANAL
CAUSE OF COUGH MAY BE
EXTRAPULMONARY.
7. Mechanism
About 2.5L of air is
inspired
Epiglottis closes,
vocal cords shut
tightly to entrap the
air within the lung
8. Abdominal muscles contract
forcefully, pushing against
the diaphragm
Internal intercosatal muscles also
contract forcefully
Pressure in the lungs rises to
100mmHg or more. Markedly
positive intrathoracic pressure
causes narrowing of the trachea.
9. Vocal cords and epiglottis
suddenly open widely .
The large pressure differential
between the airways and the
atmosphere coupled with tracheal
narrowing produces rapid flow
rates through the trachea.
Air is expelled at velocities ranging
from 75 to 100 miles/hr.
10. The shearing forces that develop aid in the
elimination of mucus and foreign materials
Cough is therefore PROTECTIVE

12. MECHANISM OF COUGH
• How Do We Cough_ - The Mechanism of
Coughing - Cough Reflex Animation - Learn
Human Body.mp4
16. D/D
• Onset- sudden onset after choking episode-
foreign body, recurrent- atopic type, chronic- TB,
bronchiectasis
• Productive- older children with early morning
severe expectoration- Bronchiectasis, non-
productive and only when awake- habitual
• Character- Barking- croup, spasmodic- atopic type
• Variation- nocturnal and early morning- atopic
type, lying down- GERD
21. CAUTION
• Pneumonia- involves parenchyma
• Cough receptors may not be involved in the
early stages
• Hence cough may be a late feature of lobar
pneumonia- Fever with tachypnea +/-
retractions is diagnostic of pneumonia
22. Productive cough: significant amount of sputum;
Blood- hemoptysis; smell- putrid smell- lung
abscess
Color of sputum- no bearing on the diagnosis
Large amounts:-
a)regular coughing up-bronchiectasis
b)Single occasion-lung abscess,empyema
c)Pink frothy-Pulmonary edema
27. 1.Diurnal variation
Cough which gets worse in night and
early morning :- Asthma
2.Postural variation
Bronchiectasis, Lung abscess
Lying down- postnasal drip, GERD,
cardiac cause- pulmonary congestion
3.Seasonal variation
Asthma, C/c bronchitis
28. Aggravating & Relieving factors
Cold,smoke,dust,exertion: asthma
Cough and choking on swallowing of
liquids: Neuromuscular disorders-
affects swallowing
Solids- Oesophageal motility problems
Otogenic cough: impacted wax or
foreign body in external auditory
meatus- subsides with removal of
cause
29. Associated symptoms
Fever: Pneumonia, lung abscess- clubbing also+
Chest pain: Pneumonia with pleuritis
Pleuritic chest pain: lateral part of chest with
associated splinting- increases on deep inspiration/
cough- Pleurisy, pleural effusion, bronchiectasis
Frequent hawking of throat, Nasal discharge, snoring,
tickling sensation in throat- Post nasal drip
Cough with associated dyspnea on exertion/
palpitations- Cardiac cause
