Rheumatic fever (acute rheumatic fever) is a disease that can affect the heart, joints, brain, and skin.
Rheumatic fever can develop if strep throat and scarlet fever infections are not treated properly.
Early diagnosis of these infections and treatment with antibiotics is key to preventing rheumatic fever.

Heart infections occur when irritants such as bacteria, viruses and fungi infect your heart. The types of heart infections are endocarditis, myocarditis and pericarditis. Providers often treat heart infections with medication, though you may need surgery for serious infections
Acute rheumatic fever is an auto immune disease, triggered by infection with specific strains of Streptococcus pyogenes, i.e. group A Streptococcus (GAS)
It affects the various organs like heart, joints, blood vessels , brain and connective tissues

The Roman Empire A Historical Colossus.pdfkaushalkr1407
The Roman Empire, a vast and enduring power, stands as one of history's most remarkable civilizations, leaving an indelible imprint on the world. It emerged from the Roman Republic, transitioning into an imperial powerhouse under the leadership of Augustus Caesar in 27 BCE. This transformation marked the beginning of an era defined by unprecedented territorial expansion, architectural marvels, and profound cultural influence.
The empire's roots lie in the city of Rome, founded, according to legend, by Romulus in 753 BCE. Over centuries, Rome evolved from a small settlement to a formidable republic, characterized by a complex political system with elected officials and checks on power. However, internal strife, class conflicts, and military ambitions paved the way for the end of the Republic. Julius Caesar’s dictatorship and subsequent assassination in 44 BCE created a power vacuum, leading to a civil war. Octavian, later Augustus, emerged victorious, heralding the Roman Empire’s birth.
Under Augustus, the empire experienced the Pax Romana, a 200-year period of relative peace and stability. Augustus reformed the military, established efficient administrative systems, and initiated grand construction projects. The empire's borders expanded, encompassing territories from Britain to Egypt and from Spain to the Euphrates. Roman legions, renowned for their discipline and engineering prowess, secured and maintained these vast territories, building roads, fortifications, and cities that facilitated control and integration.
The Roman Empire’s society was hierarchical, with a rigid class system. At the top were the patricians, wealthy elites who held significant political power. Below them were the plebeians, free citizens with limited political influence, and the vast numbers of slaves who formed the backbone of the economy. The family unit was central, governed by the paterfamilias, the male head who held absolute authority.
Culturally, the Romans were eclectic, absorbing and adapting elements from the civilizations they encountered, particularly the Greeks. Roman art, literature, and philosophy reflected this synthesis, creating a rich cultural tapestry. Latin, the Roman language, became the lingua franca of the Western world, influencing numerous modern languages.
Roman architecture and engineering achievements were monumental. They perfected the arch, vault, and dome, constructing enduring structures like the Colosseum, Pantheon, and aqueducts. These engineering marvels not only showcased Roman ingenuity but also served practical purposes, from public entertainment to water supply.

to be disproportionate to the other
findings.
The joint involvement is
characteristically migratory in nature
25.
A dramatic response to even small doses of

The response to salicylate therapy is also
much less dramatic.
49.
Only carditis cause permanent cardiac
damage.
S/O mild carditis disappear in weeks.
Sever carditis may last for 2 to 6 months.
Arthritis subside within few days to wks &
dose not cause permanent damage .
Chorea subsides in 6 to 7 months & dose not
cause permanent neurologic damage.
50.
Bed rest
Monitor closely for evidence of carditis
Ambulation as soon as the signs of acute
inflammation have subside.
Patients with carditis require longer periods
of bed rest.
51.
ANTIBIOTIC THERAPY
10 days of orally administered penicillin or
erythromycin.
Single intramuscular injection of benzathine
penicillin .
After this initial course of antibiotic
therapy, the patient should be started on
long-term antibiotic prophylaxis.
52. Oral salicylates –
Patients with typical migratory polyarthritis
and those with carditis without cardiomegaly
or CCF.
• Aspirin -100 mg/kg/24 hr divided qid PO for
3-5 days.
followed by 75 mg/kg/24 hr divided qid PO
for 4 wk.
Salicylate toxicity -tinnitus, hyperventilation.
53. CorticosteroidsPatients with carditis & cardiomegaly or CCF
Prednisone - 2 mg/kg/24 hr in 4 divided doses for
2-3 wk.
Followed by a tapering of the dose.
At the beginning of the tapering of the prednisone
dose, aspirin should be started at 75 mg/kg/24 hr
in 4 divided doses for 6 wk.
During the full course of anti-inflammatory
therapy, antacids are added to overcome irritation
to gastric mucosa.
55. Physical and emotional stress should be reduced.
Injection of benzathine penicillin for prophylaxis
indicated as in other rheumatic patients.
Anti-infalmatory drugs not needed in isolated
chorea.
For severe cases Phenobarbitone 15 to 30 mg every 6 to 8 hours.
Haloperidol (0.01-0.03 mg/kg/ 24 hr divided bid
PO)
Chlorpromazine(0.5 mg/kg q 4-6 hr PO)
56.
The more sever the cardiac involvement at
the time the patient first seen, greater the
incidence of residual heart disease.
The severity of valvular involvement increases
with each recurrence.
Valvular disease resolve more frequently
when prophylaxis is followed.
57. Prophylaxis –
Duration Ideally indefinitely.
Up to 21to 25 yrs if no evidence of valvular
involvement.
Chance of recurrence is highest in the first
5 years after the acute rheumatic fever.
58. Rheumatic Fever without 5yrs or until 21yrs –
carditis
whichever is longer
Rheumatic Fever with 10yrs or “well into
carditis but no valvular adulthood” – whichever
disease
is longer
Rheumatic Fever with At least 10yrs since last
carditis and persistent episode and at least until
40yrs;
sometimes
valvular disease
lifelong
59. Primary prevention –
Possible with a 10 days course of penicilline
therapy for streptococcal pharyngitis.
Secondary prevention-
Benzathine penicilline 1.2 million units I.M. every
28 days.
Alternative1. Oral penicilline V 250 mg twice daily
2. Oral sulfadiazine, 1 gm once daily.
3. Oral erythromycin 250 mg twice a day.
60.
61.
62.
63. During an episode of ARF, valve
changes can be minor and are still
able to regress.
After recurrent episodes of
ARF, thickening of subvalvar
apparatus, chordal thickening and
shortening and progression to
permanent valve damage is
evident.

Surveillance: incidence, prevalence, temporal
trends
Advocacy: appropriate funding of the treatment
and prevention programmes
Prevention: application of existing knowledge in
primary & secondary prevention
Editor's Notes
The Jones criteria were introduced in 1944 as a set of clinical guidelines for the diagnosis of RHF. They have subsequently undergone significant modifications ,the final ones published in 2002.These revised WHO criteria speak to the diagnosis of : a primary episode of RF recurrent attacks of RF in patients without RHD recurrent attacks of RF with RHD rheumatic chorea insidious onset rheumatic carditis chronic RHDIt is important to note that in the context of a preceding streptococcal infection, 2 major criteria, or a combination of one major and 2 minor, provide reasonable evidence for a diagnosis of RF.Major criteria: carditis, arthritis, chorea, subcutaneous nodules, erythema marginatum.Minor criteria:Clinical: fever, polyarthralgiaLab: elevated acute phase reactants ESR/CRPThis little cartoon character demonstrates the features of acute rheumatic fever. Chorea (St Vitus dance) Flitting polyarthritis- it is important to be aware that monoarthritis is an important presenting complaint in patients from developing countries WEBLINKErythema marginatum and subcutaneous nodules are the dermatological manifestations of ARF.The only manifestation of ARF with potentially life-threatening and permanent sequelae is the carditis- as evident either as valvulitis( the precursor to rheumatic heart disease) pericarditis and myocarditis.ie a pancarditis.Histologically Aschoff nodules is the hallmark pathognomonic feature and on special investigations the minor criteria such as high ESR or CRP is noted. Evidence of previous infection with GAS either via ASOT/anti-DNAse B titres or with precious evidence of streptococcus being cultured from the throat is an important adjunct to this diagnosis.Currently carditis as diagnosed by echo alone is not included in the major criteria despite repeated calls for its inclusion. It is currently recommended that all patients with the clinical diagnosis of ARF even those without clinical evidence of carditis be referred for an echocardiogram( if available)
This long axis parasternal images demonstrates the progression of valvular disease in the period between ARF and RHD. It is important to remember that timeous diagnosis, treatment and secondary prevention may in cases prevent this progression.The efficacy of echocardiographic criterions for the diagnosis of carditis in acute rheumatic fever.Vijayalakshmi IB, Vishnuprabhu RO, Chitra N, Rajasri R, Anuradha TV.Cardiol Young. 2008 Dec;18(6):586-92.
