Rheumatic Heart Disease I: Introduction

Rheumatic Heart Disease I: Introduction

Rheumatic heart disease or RHD is a chronic condition that results from rheumatic fever, causing permanent damage to the heart valves.Etiology and Risk FactorsIt primarily arises from rheumatic fever, an inflammatory disease that can develop after untreated or inadequately treated group A streptococcal (GAS) pharyngitis. Streptococcus spreads through direct contact with oral or respiratory secretions. While the bacteria are the causative agents, factors like malnutrition, overcrowding, poor...

Peripheral Artery Disease I: Introduction

Peripheral Artery Disease I: Introduction

Peripheral artery disease (PAD) predominantly results from atherosclerosis, which involves the accumulation of fatty deposits, or plaques, within the walls of arteries. This causes them to narrow and harden, significantly reducing blood flow. PAD predominantly affects the legs, particularly the arteries supplying the thighs and calves. In rare cases, it may involve other arteries, including those in the arms.Etiology of PAD:The principal cause of PAD is atherosclerosis, which results from fatty...

Nephrotic Syndrome I : Introduction

Nephrotic Syndrome I : Introduction

Nephrotic Syndrome is a chronic kidney disorder defined by clinical findings such as severe proteinuria, hypoalbuminemia, hyperlipidemia, and edema. These symptoms result from damage to the glomeruli, the kidney’s filtering units, increasing their permeability to proteins.Definition and Meaning:Proteinuria, defined as the loss of more than 3.5 grams of protein per day in adults, is a crucial feature of nephrotic syndrome. This condition is often accompanied by edema, the accumulation of...

Rheumatic Heart Disease II: Clinical Manifestations and Diagnostic Studies

The key clinical manifestations of Rheumatic heart disease (RHD) include several distinct cardiac symptoms.Carditis, a hallmark of acute rheumatic fever, involves inflammation of the heart's endocardium, myocardium, and pericardium. Chronic RHD often results from recurrent episodes of carditis. Its symptoms include the following:Murmurs are caused by valvular damage, especially to the mitral and aortic valves. Mitral stenosis or regurgitation is common, with characteristic heart murmurs...

Endocarditis II: Clinical Features of Infective Endocarditis

Endocarditis can present various clinical features depending on the causative organism and the patient's underlying health conditions. Initially, the clinical features of infective endocarditis develop gradually, presenting with nonspecific symptoms that can be easily mistaken for other illnesses.General SymptomsEarly symptoms of infective endocarditis are fever, chills, weakness, malaise, fatigue, and weight loss. These symptoms reflect the systemic nature of the infection and the body's...

Pericarditis I: Introduction

Pericarditis I: Introduction

Pericarditis is defined as the inflammation of the pericardium, the thin, sac-like membrane surrounding the heart. This condition can cause significant chest pain and other symptoms, often necessitating medical intervention. The pericardium has two layers: the inner visceral layer and the outer parietal layer, separated by a small amount of fluid that reduces friction during heartbeats.Types of PericarditisPericarditis can be classified into several types based on the duration and nature of the...

Internal Medicine
Pathology

Background:

Polyarteritis nodosa (PAN) is a systemic vasculitis primarily affecting medium-sized arteries.
Variants include cutaneous PAN and single-organ disease, complicating diagnosis and management.
PAN is increasingly recognized as a rare disease, necessitating refined diagnostic criteria.

Purpose of the Study:

To summarize the key aspects of Polyarteritis nodosa (PAN).
To highlight diagnostic approaches and treatment strategies for PAN.
To underscore the importance of international collaboration in vasculitis research.

Main Methods:

Histologic confirmation of vasculitis in medium-sized arteries is the gold standard.
Biopsies should target symptomatic and least invasive sites for diagnostic yield.
Angiography can reveal characteristic microaneurysms in visceral arteries.

Main Results:

Treatment typically involves high-dose corticosteroids.
Immunosuppressive agents are added for internal organ involvement or life-threatening disease.
Maintenance therapy is initiated upon achieving remission.

Conclusions:

Accurate diagnosis of PAN relies on integrated clinical, histologic, and imaging findings.
Effective management requires a multi-drug approach tailored to disease severity.
Ongoing international efforts aim to improve the classification and diagnosis of PAN and other vasculitides.
