Skin Diseases and Disorders

3.9K
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...

Skin Cancer01:30

Skin Cancer

4.2K
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 Dermis01:11

Papillary Dermis

3.0K
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...

Accessory Structures of the Skin: Nails

1.8K
Nails are one of the important accessory structures of the skin. They are hard, protective structures that cover the dorsal surface of the distal phalanges of fingers and toes. Nails are composed of specialized keratinized cells and serve various functions, including protection, sensation, and manual dexterity.
The main components of a nail include the following.
Nail Plate: The nail plate is the visible portion of the nail that extends beyond the fingertips or toes. It is a hard, translucent...

Endocarditis II: Clinical Features of Infective Endocarditis

14
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...

Reticular Dermis01:15

Reticular Dermis

2.6K
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...

Area of Science:

  • Dermatology
  • Toxicology
  • Botany

Background:

  • Semecarpus anacardium (marking nut) belongs to the Anacardiaceae family, related to poison ivy.
  • Its urushiol compound can cause irritant or allergic contact dermatitis.
  • Marking nut dermatitis is significant in military dermatology.

Observation:

  • Five cases of factitious dermatitis were observed.
  • These cases resulted from the deliberate application of marking nut.
  • Exposure occurred during recreational activities like camping.

Findings:

  • Factitious dermatitis presents a diagnostic challenge.
  • The urushiol in marking nut causes significant skin reactions.
  • Differential diagnosis includes irritant and allergic contact dermatitis.

Implications:

  • Awareness of marking nut dermatitis is crucial for clinicians, especially in military settings.
  • Understanding deliberate self-harm with plant-based toxins is important for patient management.
  • Proper identification and patient history are key to diagnosing factitious dermatitis.
