Endocarditis II: Clinical Features of Infective Endocarditis

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...

Skin Diseases and Disorders

Skin Diseases and Disorders

Skin is the first line of defense and encounters a variety of microbes. Some pathogenic strains are often the cause of a broad range of infections of the skin and other body systems. These conditions can affect people of all ages and may have different causes, including genetic factors, infections, autoimmune reactions, environmental factors, and lifestyle choices.
Gram-positive Staphylococcus spp. and Streptococcus spp. are responsible for many of the most common skin infections. However, many...

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...

Clinical Applications of Epidermal Stem Cells

Clinical Applications of Epidermal Stem Cells

Epidermal stem cells (EpiSCs) are mainly located at the basal layer of the epidermis. These cells repair minor injuries of the skin and replace dead skin cells. However, EpiSCs’ cannot heal severe wounds such as major burns or those from diabetes or hereditary disorders. In such cases, culturing the epidermal stem cells from the patient is possible and has yielded successful treatment options, such as laboratory-grown skin grafts. These grafts are synthesized using a patient’s own...

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...

Reticular Dermis

Reticular Dermis

The papillary and reticular dermis are the two layers of the dermis. They are made of connective tissue with fibers of collagen extending from one to the other, making the border between the two somewhat indistinct. The dermal papillae extending into the epidermis belong to the papillary layer, whereas the dense collagen fiber bundles below belong to the reticular layer.
Reticular Layer
Underlying the papillary layer is the much thicker reticular layer, composed of dense, irregular connective...

Summary

This summary is machine-generated.

Recurrent cutaneous necrotising eosinophilic vasculitis (RCNEV) is a rare condition. Corticosteroids are effective but relapses occur, necessitating steroid-sparing treatments.

Area of Science:

Dermatology
Rheumatology
Pathology

Background:

Recurrent cutaneous necrotising eosinophilic vasculitis (RCNEV) is a rare vasculitic disorder.
First described in 1994, RCNEV presents unique histopathological features.

Observation:

RCNEV predominantly affects middle-aged females from Asia.
Clinical presentation includes erythematous to purpuric papuloplaques and angio-oedema of extremities.
Peripheral eosinophilia is a common finding.

Findings:

Histopathology reveals exclusive eosinophilic infiltration around vascular plexuses.
Absence of leukocytoclasis and fibrinoid degeneration of vascular walls are characteristic.
Corticosteroid therapy shows efficacy, but relapses are noted during dose tapering.

Implications:

Understanding RCNEV pathogenesis is crucial for effective management.
Differential diagnosis requires careful consideration of eosinophilic infiltration patterns.
Exploration of steroid-sparing therapies is essential for long-term patient care.
