This document discusses acute rheumatic fever in children. It begins by noting that rheumatic heart disease is the most common acquired heart disease in children worldwide, especially in developing countries. It then describes the pathogenesis of acute rheumatic fever and rheumatic heart disease, caused by an autoimmune response to group A streptococcal infection. The document outlines the revised Jones criteria for diagnosing acute rheumatic fever and reviews treatment recommendations, including antibiotic therapy, anti-inflammatory drugs, and secondary prophylaxis to prevent recurrent episodes of rheumatic fever and progression of cardiac damage.
Cardiovascular history taking is an important skill that is often assessed in bedside teaching . It’s important to have a systematic approach to ensure you don’t miss any key information. The guide below provides a framework to take a thorough cardiovascular history.
These are cardiac anomalies arising as a result of a defect in the structure or function of the heart and great vessels which is present at birth
These lesions either obstruct blood flow in the heart or vessels near it, or alter the pathway of blood circulating through the heart

CRISPR-Cas9, a revolutionary gene-editing tool, holds immense potential to reshape medicine, agriculture, and our understanding of life. But like any powerful tool, it comes with ethical considerations.
Unveiling CRISPR: This naturally occurring bacterial defense system (crRNA & Cas9 protein) fights viruses. Scientists repurposed it for precise gene editing (correction, deletion, insertion) by targeting specific DNA sequences.
The Promise: CRISPR offers exciting possibilities:
Gene Therapy: Correcting genetic diseases like cystic fibrosis.
Agriculture: Engineering crops resistant to pests and harsh environments.
Research: Studying gene function to unlock new knowledge.
The Peril: Ethical concerns demand attention:
Off-target Effects: Unintended DNA edits can have unforeseen consequences.
Eugenics: Misusing CRISPR for designer babies raises social and ethical questions.
Equity: High costs could limit access to this potentially life-saving technology.
The Path Forward: Responsible development is crucial:
International Collaboration: Clear guidelines are needed for research and human trials.
Public Education: Open discussions ensure informed decisions about CRISPR.
Prioritize Safety and Ethics: Safety and ethical principles must be paramount.
CRISPR offers a powerful tool for a better future, but responsible development and addressing ethical concerns are essential. By prioritizing safety, fostering open dialogue, and ensuring equitable access, we can harness CRISPR's power for the benefit of all. (2998 characters)

1. ACUTE RHEUMATIC FEVER
IN CHILDREN
Dr.S.Srinivasan
Professor of Paediatrics
MBBS – Medical Undergraduate Theory
Lecture for 8th and 9th Semester Students
ARF -Dated: 11th February 2016
2. World Heart Federation
“ Rheumatic heart disease (RHD) is the most
common acquired heart disease in children in
many countries of the world, especially in
developing countries.
The global burden of disease caused by rheumatic
fever currently falls disproportionately on
children living in the developing
world, especially where poverty is widespread ”
3. Immuno-pathogenesis of
Acute Rheumatic Fever & RHD
• Group A Beta Hemolytic Streptococcal infection
• Autoantibody response against the heart
• (Anti-myosin antibodies)
• Antibody deposition on heart valve endothelium and in
the myocardial vessels and tissues.
• Infiltration of myocardium and valvular region with
macrophages and autoreactive T lymphocytes.
• Destruction of myofibers
• (Cardiomyocytes in myocardium)
• Valvulitis, Scarring, collagen deposition
• (Heart murmur)
ARF -Dated: 11th February 2016

of the throat culture results to eradicate GABS from the
upper respiratory tract.
or 10 days of orally administered Penicillin or Erythromycin
Anti-inflammatory Therapy
Aspirin (Arthritis) & Prednisolone + Aspirin (Carditis)
General Measures -
Rest and ambulation
Ambulate as soon as the signs of acute inflammation have
subsided with longer periods of bed rest for carditis children
8. Treatment of Acute Rheumatic Fever
Clinical condition Anti-inflammatory Drug
Arthralgia Any analgesic can be used
Arthritis Aspirin 100mg/kg/day in divided doses for two
weeks followed by 75mg/kg/day in divided doses
for 4-6 weeks.
Carditis with
cardiomegaly or
CHF
Prednisolone 2mg/kg/day in divided doses x 2
weeks
Tapering dose to be stopped in another two
weeks.
While tapering Steroids, Start
Aspirin 75mg/kg/day in divided doses for 4-6
weeks to prevent re-bound phenomena.
CHF Antifailure measures – Bed Rest , Diuretics,
Digoxin, Salt Restricted Diet.
9. Duration of Acute Rheumatic Fever
• Average : About 12 weeks
• Rarely prolonged even up to 6 months
especially with carditis or chorea
• “ Chronic Rheumatic Fever ”:
Rare (active for more than six months )
10. COURSE AND PROGNOSIS of ARF
“Rheumatic Fever licks the joints and bites the heart”
(1884, Lasegue)
PROGNOSIS
Arthritis Good prognosis
Chorea
Carditis 25% ( 1in 4 ) of RF patients : Residual heart disease (
MR,MS,AR,AS ) If carditis is limited to systolic murmur
ARF with congestive cardiac failure develops chronic
valvular heart disease over a period of 5-10 years
Death
during
acute ARF
Rare in the past 30 years
( better awareness and early Health seeking behaviour
and treatment facilities )
