Endocarditis II: Clinical Features of Infective Endocarditis

662
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 Cancer

6.4K
Skin cancer is a type of cancer that occurs when there is an abnormal growth of skin cells, usually triggered by damage to the DNA within the skin cells. It is primarily caused by exposure to ultraviolet (UV) radiation from the sun or artificial sources like tanning beds. Skin cancer is the most common type of cancer worldwide, and its incidence continues to rise.
Basal Cell Carcinoma (BCC): BCC is the most common type of skin cancer, accounting for about 80% of cases. It typically develops in...

Papillary Dermis

6.5K
Dermis
The dermis might be considered the "core" of the integumentary system, as distinct from the epidermis and hypodermis. It contains blood and lymph vessels, nerves, and other structures, such as hair follicles and sweat glands. The dermis is made of two layers of connective tissue that comprise an interconnected mesh of elastin and collagenous fibers, produced by fibroblasts.
Papillary Layer
The papillary layer is made of loose, areolar connective tissue, which means the collagen...

Reticular Dermis01:15

Reticular Dermis

5.3K
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...

Skin Diseases and Disorders

6.0K
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...

Changes in Skin Color: Clinical Perspectives

4.0K
The first thing a clinician sees is the skin, so the examination of the skin should be part of any thorough physical examination. Most skin disorders are relatively benign, but a few, including melanomas, can be fatal if untreated. A couple of the more noticeable disorders, albinism and vitiligo, affect the appearance of the skin and its accessory organs.
Albinism
Albinism is a genetic disorder that affects (completely or partially) the coloring of skin, hair, and eyes. The defect is primarily...

    Area of Science:

    • Dermatology
    • Infectious Diseases
    • Immunology

    Background:

    • Erythema nodosum (EN) is an inflammatory condition characterized by tender subcutaneous nodules.
    • While often idiopathic, EN can be associated with infections, autoimmune diseases, and medications.
    • Understanding triggers is crucial for effective management and diagnosis.

    Observation:

    • Three young female patients presented with plaque-type erythema nodosum.
    • The onset of EN lesions was acute in all cases.
    • Patients were undergoing treatment for their respective underlying conditions at the time of EN development.

    Findings:

    • Case 1: Tuberculosis of the chest was the underlying cause of EN.
    • Case 2: Recurrent furunculosis (bacterial skin infection) triggered EN.
    • Case 3: Malaria infection led to the development of EN.

    Implications:

    • Highlights the diverse range of infectious etiologies for erythema nodosum.
    • Suggests that EN can manifest acutely even during active treatment for underlying conditions.
    • Emphasizes the importance of a thorough etiological workup for EN, particularly in young females.
    • Underscores the need to consider infections like tuberculosis, furunculosis, and malaria in the differential diagnosis of EN.
