Emphysema is a type of COPD involving damage to the air sacs (alveoli) in the lungs. As a result, your body does not get the oxygen it needs. Emphysema makes it hard to catch your breath. You may also have a chronic cough and have trouble breathing during exercise. The most common cause is cigarette smoking
Normally, the pleural space contains a small amount of fluid (5 to 15 mL), which acts as a lubricant that allows the pleural surfaces to move without friction.
But if fluid builds up from either increased production or inadequate removal pleural effusion results.
Pleural effusion B/L or unilateral (parapneumonic process)
Refers to any significant collection of fluid within pleural space.
Any imbalance in formation, absorption lead accumulation of pleural fluid. Common condition:
CHF
Bacterial pneumonia
Malignancy(chest tumor)
Pulmonary embolism
Pleura effusion is a condition refers to a collection of fluid in the pleural space. It is almost secondary to other conditions.
Lung abscess is a type of liquefactive necrosis of the lung tissue and formation of cavities (more than 2 cm) containing necrotic debris or fluid caused by microbial infection.

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.

June 3, 2024 Anti-Semitism Letter Sent to MIT President Kornbluth and MIT Cor...Levi Shapiro
Letter from the Congress of the United States regarding Anti-Semitism sent June 3rd to MIT President Sally Kornbluth, MIT Corp Chair, Mark Gorenberg
Dear Dr. Kornbluth and Mr. Gorenberg,
The US House of Representatives is deeply concerned by ongoing and pervasive acts of antisemitic
harassment and intimidation at the Massachusetts Institute of Technology (MIT). Failing to act decisively to ensure a safe learning environment for all students would be a grave dereliction of your responsibilities as President of MIT and Chair of the MIT Corporation.
This Congress will not stand idly by and allow an environment hostile to Jewish students to persist. The House believes that your institution is in violation of Title VI of the Civil Rights Act, and the inability or
unwillingness to rectify this violation through action requires accountability.
Postsecondary education is a unique opportunity for students to learn and have their ideas and beliefs challenged. However, universities receiving hundreds of millions of federal funds annually have denied
students that opportunity and have been hijacked to become venues for the promotion of terrorism, antisemitic harassment and intimidation, unlawful encampments, and in some cases, assaults and riots.
The House of Representatives will not countenance the use of federal funds to indoctrinate students into hateful, antisemitic, anti-American supporters of terrorism. Investigations into campus antisemitism by the Committee on Education and the Workforce and the Committee on Ways and Means have been expanded into a Congress-wide probe across all relevant jurisdictions to address this national crisis. The undersigned Committees will conduct oversight into the use of federal funds at MIT and its learning environment under authorities granted to each Committee.
• The Committee on Education and the Workforce has been investigating your institution since December 7, 2023. The Committee has broad jurisdiction over postsecondary education, including its compliance with Title VI of the Civil Rights Act, campus safety concerns over disruptions to the learning environment, and the awarding of federal student aid under the Higher Education Act.
• The Committee on Oversight and Accountability is investigating the sources of funding and other support flowing to groups espousing pro-Hamas propaganda and engaged in antisemitic harassment and intimidation of students. The Committee on Oversight and Accountability is the principal oversight committee of the US House of Representatives and has broad authority to investigate “any matter” at “any time” under House Rule X.
• The Committee on Ways and Means has been investigating several universities since November 15, 2023, when the Committee held a hearing entitled From Ivory Towers to Dark Corners: Investigating the Nexus Between Antisemitism, Tax-Exempt Universities, and Terror Financing. The Committee followed the hearing with letters to those institutions on January 10, 202

4. Anatomy and physiology
The respiratory tract extends from the nose to
the alveoli and includes not only the air-
conducting passages also but the blood supply
The primary purpose of the respiratory system
is gas exchange, which involves the transfer of
oxygen and carbon dioxide between the
atmosphere and the blood.
The respiratory system is divided into two
parts: the upper respiratory tract and the
lower respiratory tract
5. The nose
pharynx
adenoids
tonsils
epiglottis
larynx,
and trachea.
The upper respiratory tract includes
6. The lower respiratory tract
consists of
the bronchi,
Bronchioles
alveolar ducts
and alveoli
With the exception of the right and left
main-stem bronchi, all lower airway
structures are contained within the
lungs.
7. The right lung is divided into three lobes
(upper, middle, and lower)
the left lung into two lobes (upper and
lower)
The structures of the chest wall
(ribs, pleura, muscles of respiration) are
also essential

10. Physiology of Respiration
Ventilation. Ventilation involves inspiration (movement of
air into the lungs) and expiration (movement of air out of the
lungs). Air moves in and out of the lungs because intrathoracic
pressure changes in relation to pressure at the airway opening.
Contraction of the diaphragm and intercostal and scalene
muscles
increases chest dimensions, thereby decreasing intrathoracic
pressure. Gas flows from an area of higher pressure
(atmospheric)
to one of lower pressure (intrathoracic)

15. Position/Lighting/Draping
Position –
patient should sit upright on the examination table.
The patient's hands should remain at their sides.
When the back is examined the patient is usually
asked to move their arms forward (hug themself
position) so that the scapulae are not in the way of
examining the upper lung fields.
Lighting - adjusted so that it is ideal.
Draping - the chest should be fully exposed.
Exposure time should be minimized.
16. The basic steps of the
examination
can be remembered with the
mnemonic IPPA:
Inspection
Palpation
Percussion
Auscultation

increase end expiratory pressure)
Accessory muscle use (scalene muscles)
Diaphragmatic paradox - the diaphragm moves
opposite of the normal direction on inspiration;
suspect flail segment in trauma
Intercostal indrawing

26. Palpation
Tactile fremitus
is vibration felt by palpation. Place your open palms against
the upper portion of the anterior chest, making sure that
the fingers do not touch the chest. Ask the patient to
repeat the phrase “ninety-nine” or another resonant
phrase while you systematically move your palms over
the chest from the central airways to each lung’s
periphery.You should feel vibration of equally intensity on
both sides of the chest. Examine the posterior thorax in a
similar manner. The fremitus should be felt more strongly
in the upper chest with little or no fremitus being felt in the
lower chest
27. Assessing chest expansion in expiration (left) and inspiration (right).
Direct percussion of the clavicles for
disease in the lung apices
Percussion over the anterior chest.
28.
29. Auscultation
To assess breath sounds, ask the patient
to breathe in and out slowly and deeply
through the mouth.
Begin at the apex of each lung and
zigzag downward between intercostal
spaces . Listen with the diaphragm
portion of the stethoscope.
32. Normal Breath Sounds
Bronchial: Heard over the trachea and mainstem bronchi (2nd-4th
intercostal spaces either side of the sternum anteriorly and 3rd-6th
intercostal spaces along the vertebrae posteriorly). The sounds are
described as tubular and harsh. Also known as tracheal breath sounds.
Bronchovesicular: Heard over the major bronchi below the clavicles in
the upper of the chest anteriorly. Bronchovesicular sounds heard over
the peripheral lung denote pathology. The sounds are described as
medium-pitched and continuous throughout inspiration and expiration.
Vesicular: Heard over the peripheral lung. Described as soft and low-
pitched. Best heard on inspiration.
Diminished: Heard with shallow breathing; normal in obese patients
with excessive adipose tissue and during pregnancy. Can also indicate
an obstructed airway, partial or total lung collapse, or chronic lung
disease.
35. Tactile Fremitus
Ask the patient to say "ninety-nine" several
times in a normal voice.
Palpate using the ball of your hand.
You should feel the vibrations transmitted
through the airways to the lung.
Increased tactile fremitus suggests
consolidation of the underlying lung tissues
