Skin Cancer01:30

Skin Cancer

5.6K
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

5.2K
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

4.3K
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

5.0K
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...

Accessory Structures of the Skin: Hair and Hair Follicles01:16

Accessory Structures of the Skin: Hair and Hair Follicles

4.0K
Hair and hair follicles are integral components of the integumentary system. Hair is a filamentous structure composed mainly of a protein called keratin. It is found on the surface of the skin throughout the body, except for areas such as the palms of the hands and soles of the feet.
Hair is a keratinous filament growing out of the epidermis. It is primarily made of dead, keratinized cells. Hair strands originate at the epidermal penetration called the hair follicle. The hair shaft is the part...

Primary Lymphoid Organs01:16

Primary Lymphoid Organs

14.3K
Primary lymphoid organs are pivotal in the formation, development, and maturation of lymphocytes, the white blood cells that serve as the backbone of our immune system. This crucial function underscores their fundamental role in maintaining our overall health and immunity. The two primary lymphoid organs of prime importance are the red bone marrow and the thymus.
The red bone marrow is a soft, spongy tissue nestled in the interior of long bones such as the humerus and femur. It is the site...

Area of Science:

  • Dermatology
  • Immunology
  • Neurology

Background:

  • Prurigo nodularis represents the most severe form of chronic prurigo.
  • It is characterized by disseminated nodules, primarily on the limbs, accompanied by skin excoriations and intense pruritus.
  • This condition is considered an autonomous disease linked to itch sensitization, akin to pain sensitization.

Purpose of the Study:

  • To review the characteristics of prurigo nodularis.
  • To discuss the high burden associated with the disease.
  • To explore current and future management strategies.

Main Methods:

  • Literature review of prurigo nodularis.
  • Analysis of disease characteristics and patient burden.
  • Overview of therapeutic approaches and research perspectives.

Main Results:

  • Prurigo nodularis presents with significant physical and psychological burden.
  • Management often necessitates a multi-level approach and specialist dermatological input.
  • Ongoing research indicates potential for novel therapeutic interventions.

Conclusions:

  • Prurigo nodularis is a debilitating condition requiring comprehensive management.
  • Understanding itch sensitization is key to managing the disease.
  • Promising therapeutic avenues are emerging from ongoing research.
