Examination of cardiovascular system in PediatricsBirhanu Melese
The paediatrics cardiovascular exam can be a logistical minefield, requiring a good understanding of cardiac anatomy and possible congenital anomalies. With babies especially, it’s important to be opportunistic with your examination – doing the three ‘quiet things’ first: auscultation of heart sounds, auscultation of breath sounds and palpation of femoral pulses.
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

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.
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.

3. The History
Symptoms of Heart Disease
Dyspnea: This is a state of shortness of
breath on exertion. But, it may occur at rest
as the heart failure progresses. The degree
dyspnea is graded based on the New York
Heart Association Class (NHAC)
4. Cont…
Paroxysmal Nocturnal Dyspnea: Is
shortness of breath that occurs during sleep.
The patient suddenly wakes up due the
shortness of breath and then sits up or rush to
open a window/door to get fresh air.
Orthopnea: Shortness of breath that
occurs during recumbent position.
It is gauged by the number of pillows that are
used to relieve the symptom
5. Cont…
Body swelling: Usually which starts from the leg
Palpitation: Is subjective unpleasant perception of
one’s own heart beat.
Cough: Which usually occurs at night (nocturnal)
•Syncope: Sudden episode of fainting related to
hemodynamic derangement.
Pain: Angina pectoris is a cardiac pain. It arises in the
precordial area usually on the retrosternal region and
radiates to the left neck, shoulder and left upper arm. It
has piercing, or squeezing character which is aggravated
by exertion and relieved by rest

◦ Pericardial disease
11
There are also non cardiac causes of
dyspnoea

18. Cont…
Equipment Needed
◦ Stethoscope
◦ A Blood Pressure apparatus
◦ A Moveable Light Source or pen light
19. General Considerations
The patient must be properly
undressed above the waist.
The examination room must be quiet to
perform adequate auscultation.
Observe the patient for general signs of
cardiovascular disease
◦ Breathing pattern
◦ Cyanosis,
◦ Finger clubbing,
◦ Edema
20. Arterial Pulses
Components of arterial examination
include
◦ ƒ
Rate
◦ ƒ
Rhythm
◦ ƒ
Character
◦ ƒ
Volume (amplitude)
◦ ƒ
Radio-femoral dela
21. Cont…
Major Arteries: Major arteries Radial,
Brachial, Carotid,Femoral, Popliteal,
Posterior Tibial, Dorsalis pedis.
All arteries should be palpated
symmetrically at the same time except
carotid arteries, as this could cut off
the blood supply to the brain and cause
syncope.
22. Cont…
Rate and Rhythm: The radial artery is
preferred
Compress the radial artery with your index
and middle fingers
Note whether the pulse is regular or
irregular.
Count the pulse for one full minute.
Record the rate and rhythm.
23. Cont…
Pulse classification in adults
1. Based on the rate
Normal: 60 - 100 beats / min
Bradycardia: < 60 beats / min
Tachycardia: > 100 beats / min
2. Based on rhythm
Regular
Regularly irregular; e.g. ectopic beats,
2nd
degree heart block
Irregularly irregular: e.g. atrial fibrillation
24. Blood Pressure 90 – 140, Diastolic: 60 – 85 millimeter of
mercury
1. Position the patient's arm so that the anticubital fold is level with the
heart.
2. Center the bladder of the cuff over the brachial artery approximately 2
cm above the anticubital fold. Proper cuff size is essential to obtain an
accurate reading Physical Diagnosis
3. Palpate the radial pulse and inflate the cuff until the pulse disappears
4. Place the stethoscope over the brachial artery.
5. Inflate the cuff 20 to 30 mmHg above the estimated systolic pressure
after the pulse disappears.
6. Release the pressure slowly, no greater than 5 mmHg per second.
7. The level at which you consistently hear beats is the systolic pressure.
8. Continue to lower the pressure until the sounds muffle and
disappear. This is the diastolic pressure.
9. Record the blood pressure as systolic over diastolic (e.g. 120/70).
10. Blood pressure should be taken in both arms on the first encounter.
25. Cont…
Character and Volume: best checked on
carotid arteries
Observe for carotid pulsations.
Place fingers behind the patient's neck and
compress the carotid on one side
Assess the following:
The amplitude of the pulse.
The contour of the pulse wave.
Variations in amplitude from beatto beat or with
respiration.
Repeat on the opposite side.
26. Venous system
Jugular Venous Pressure (JVP):- is a
reflection of the right atrial pressure
and it is the most important part of
venous system examination
27. Interpretation:
Normal: - is less than or equal to 4 cm
of water
Elevated: - if greater than 4 cm of
water above the sternal angle.
This indicates raised right atrial
pressure which is most often found in
right ventricular failure (dysfunction)
28. The Precordium
This is part of the anterior chest wall
which overlies the heart. During
examination of the precordium:-
◦ Position the patient supine with the head
of the table slightly elevated
◦ Always examine from the patient's right
side
29. Cont…
Inspection
◦ Precordial bulge which may indicatelong
standing cardiac diseases
◦ Precordial movement( activity ):-
◦ Multiple pulsations:- e.g. multivalvular
lesions
◦ Quiet: - e.g. Pericardial effusion
◦ Apical beat: - which is the most laterally
and downward positioned impulse
30. Palpation
• Palpable heart sounds (at each
valvular sites)
• PMI: point of maximal impulse
(which usually is located at the same
area to the apical impulse,).
It is normally located in the 4th or 5th
intercostals space just medial to the
mid clavicular line and properly
characterizes the PMI.
31. Auscultation
The stethoscope has two parts:-
Diaphragm:preferred to auscultate high pitched
sounds e.g. S1, S2, Holosystoic murmur etc
Bell: preferred to auscultate low pitched sounds
e.g. S3, S4, diastolic murmur of MS
Position the patient supine with the head
of the table slightly elevated.
Always examine from the patient's right
side
32. Areas of auscultation
1. The right 2nd inters space near the sternum
(aortic area).
2. The left 2nd inter space near the sternum
(pulmonic area).
3. The left 4th , and 5th inter spaces near the
sternum (tricuspid area)
4. At the apex (mitral area).
33. Different maneuvers to accentuate
cardiac auscultation
◦ Have the patient roll on their left side and
auscultate at the apex. This position
accentuates S3 and mitral murmurs.
◦ Have the patient sit up and lean forward.
This position enhances diastolic murmur of
aortic regurgitation, and pericardial friction
rub
34. Cont…
During auscultation focus on
◦ 1st Heart Sound, S1:- This signals the
onset of systole and is caused by the
closure of the mitral and tricuspid valves.
35. 1st Heart Sound
, S1:- This signals the onset of systole and is
caused by the closure of the mitral and tricuspid
valves.
S1 is loud in
mitral stenosis
tachycardia
hyperdynamic circulation like e.g. anemia
S1 is soft ( Muffled )in:-
mitral regurgitation
bradycardia and LVF
36. S2 Heart Sound
Heard particularly during inspiration
The sound is made by the closure of aortic and
pulmonary valves
3rd Heart Sound, S3
This is produced by rapid ventricular filling and
occurs in early-mid diastole i.e. soon after S2 occurs
normally in young fit adults with bradycardia
patients with heart failure
left heart failure - S3 heard best in mitral area
right heart failure - S3 heard best in tricuspid area
patients with high ventricular filling pressure
mitral regurgitation
37. 4th Heart Sound, S4
This is an atrial sound, occurring just
before S1. It is always abnormal as it
represents
atrial contraction against a stiffened
ventricle e.g. due to aortic stenosis or
hypertensive heart disease.
It may also occur in heart failure.
38. Cont…
• 2nd Heart Sound, S2: The sound is made
by the closure of aortic and pulmonary
valves
3rd & 4th Heart Sounds
◦ These are low pitched sounds
◦ If either S3 or S4 is very loud it is often
heard as gallop/triple rhythm
39. Murmur
Murmur is abnormal sound due to
turbulence of blood flow.
It may be innocent (Physiologic) e.g.
hyperdynamic states like anemia,
pregnancy etc. or pathologic e.g.
valvular lesions
40. Cont…
Characterization of Murmur
◦ Timing: systole, diastole, continuous
◦ Point of maximum intensity (PMI)
◦ Direction of selective propagation
(radiation)
◦ The character and quality of the murmur
◦ Intensity (grading)
41. Classification of Murmurs
Systolic murmurs
1) Ejection systolic murmur
◦ This originates from the aortic outflow tract.
It may be an innocent flow murmur which is
◦ common in childhood, pregnancy, anemia or
◦ pathological murmur as in
Aortic stenosis and Aortic sclerosis
Hypertrophic obstructive cardiomyopathy
Pulmonary stenosis
Atrial septal defect
42. Cont…
2. Pansystolic murmur:
It is of uniform intensity and merges with
S2.
S1 is often muffled. It is found in:-
Mitral or Tricuspid regurgitation
Ventricular septal defect
43. Cont…
Diastolic murmurs
1) Early diastolic murmur: This is high-
pitched and blowing. It occurs due to:-
◦ Aortic or pulmonary regurgitation.
2) Mid-diastolic murmur: This is low-
pitched and rumbling; it often starts
after an opening
snap. It is caused by:- mitral
stenosis(common)
Description:– Fast or slow.– Regular or irregular.– Onset and offset:Sudden onset and offset in paroxysmal supraventricular tachycardia or paroxysmal atrial fibrillation.– Duration.– Associated symptoms: dizziness, presyncope and syncope, chest pain, dyspnea, polyuria, pallor.
Face
• Malar flush (thin face, purple cheeks) may be found in mitral stenosis.
• Lips for (cyanosis).
Eyes
• Xanthelasma or corneal arcus indicates hyperlipidemia
• Pallor of the conjunctiva indicates anemia
• Icterus may be found in acutely congested liver
• Exophthalmus may be seen in thyrotoxicosis.
Hands
• Clubbingof fingers may be seen :
o Cyanotic congenital heart disease
o Infective endocarditis
• Peripheral cyanosisand Perfusion
• Splinter hemorrhages:- vertical linear hemorrhages beneath the nails
• Osler's nodes:- Tender lumps in pulp of fingertips which may be found in
endocarditis
• Janeway lesions:- are painless red macules on the wrist and palm which may be
seen in patients with acute infective endocarditis
• Nicotine stains:- indicate chronic smoking which is a major risk factor for
atherosclerosis.
Carotid pulse - for character
• Normal
• Hypokinetic (small volume):found in low output states like heart failure, shock,
mitral stenosis etc.
• Parvus et tardus ( Small Volume And Slow Rising pulse ): found in aortic stenosis
• Bisferiens: a collapsing and slow rising pulse which occurs in mixed aortic
disease (AS and AR )
• Pulsus alternans: alternating strong and week pulses
• Jerky- hypertrophic cardiomyopathy
• Pulsus Paradoxus: pulse weakens in inspiration, indicates tamponade or
constrictive pericarditis
• Collapsing(rapid up and rapid down): Water hammer pulse
o strong radial pulse that taps hand up on lifting the arm
o indicates wide pulse pressure of aortic regurgitation (also AV fistula or
hyperdynamic circulation)
• Bounding pulse
o CO2retention
o Liver failure
o Sepsis
• Radio-femoral delay- suggests coarctation or dissection of aorta
Position the patient supine with the head of the table elevated 30 degrees
Use tangential, side lighting to observefor venous pulsations in the neck.
Look for a rapid, double (sometimestriple) wave with each heartbeat.
Adjust the angle of table elevation to bring out the venous pulsation.
5. Identify the highest point ofpulsation. Using a horizontal line from this point,
measure vertically from the sternal angle
This measurement should be less than 4 cm in a normal healthy adult
Interpretation:
Normal: - is less than or equal to 4 cm of water
Elevated: -if greater than 4 cm of water above the sternal angle.
This indicates raised right atrial pressure which is most often found in right ventricular
failure (dysfunction)
Ask the patient to hold on breathing on inspiration which makes sounds arising from the
right side of the hear louder , and
if the patient holds on expiration sound originating from the left side of the heart are exaggerated.
NB The 1st sound can be identified by palpating the carotid pulse while auscultating. The
upstroke of the carotid pulse closely follows the 1st heart beat.
S1is loud in
o mitral stenosis
o tachycardia
o hyperdynamic circulation like e.g. anemia
• S1is soft ( Muffled )in:-o
mitral regurgitation
bradycardia and LVF
The aortic valve closes before the pulmonary valve and this splitting of the second sound is heard particularly during inspiration, as more blood is drawn into the right ventricle which is a normal phenomenon.
S2 wide splittingoccurs in
right bundle branch block
pulmonary stenosis
Wide and fixed splitting (i.e. not varying with respiration) occurs when there is an atrial septal defect
A2is loud in systemic hypertension
• A2 is soft in aortic stenosis
• P2is loud in pulmonary hypertension
• P2is soft in pulmonary stenosis
The aortic regurgitation murmur is usually soft and is best heard with the patient leaning forward and in expiration.
• mitral stenosis(common)
exhibits pre-systolic accentuation in sinus rhythm o amplified by rolling the patient into the left lateral position
Rheumatic fever
thickens mitral valve leaflets Is called Carey Coombs' murmur
aortic regurgitation regurgitant jet causes fluttering of anterior mitral valve cusp Is called Austin Flint murmur tricuspid stenosis(rare) large atrioseptal defect
