Summary
Chronic prurigo, often called prurigo nodularis, is a skin condition characterized by intense itching and scratching. Recent research highlights neuroimmune interactions, offering new therapeutic avenues beyond current disappointing treatments.
Area of Science:
- Dermatology
- Neuroscience
- Immunology
Background:
- Chronic prurigo, frequently termed prurigo nodularis, is defined by persistent itching, scratching, and characteristic skin lesions.
- Its pathophysiology involves neural sensitization and a pruritus-scratching cycle, with diverse potential origins including allergies, systemic diseases, and neurological factors.
Purpose of the Study:
- To summarize recent advancements in the nosology and research of chronic prurigo.
- To discuss current and emerging therapeutic strategies for managing this condition.
Main Methods:
- Review of recent developments in basic, epidemiological, and clinical research on chronic prurigo.
- Analysis of current and near-future management options.
Main Results:
- The definition and understanding of chronic prurigo have recently evolved, moving beyond its previously vague characterization.
- Emerging research on neuroimmune interactions in pruritus pathophysiology opens promising therapeutic avenues.
Conclusions:
- Chronic prurigo presents a significant burden, with current treatments often being unsatisfactory.
- Novel therapies targeting T-helper 2 cytokines, kappa-opioids, and Janus kinase inhibitors show promise for future management.

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...

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...

01:24Chronic Pancreatitis I: Introduction
174
The pancreas, an elongated and flat gland situated behind the stomach, serves a vital function in digesting food and managing blood sugar levels.
Pancreatitis is the inflammation of the pancreas, which occurs when the immune system becomes active and causes swelling, pain, and disruptions in organ function. Pancreatitis can manifest as either an acute or chronic condition.
Acute pancreatitis arises suddenly and lasts for a brief duration, while chronic pancreatitis is a long-term affliction...

3.1K
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...

01:21Accessory Structures of the Skin: Sebaceous Glands
2.4K
A sebaceous gland is a type of oil gland found almost all over the skin ( except palms and soles) and helps lubricate and waterproof the skin and hair. Most sebaceous glands are associated with hair follicles. They generate and excrete sebum, a mixture of lipids, onto the skin surface, thereby naturally lubricating the dry and dead layer of keratinized cells of the stratum corneum, keeping it pliable.
These glands that produce the oils on the skin and hair are holocrine glands. The mature...

01:20Accessory Structures of the Skin: Hair Growth and Types
1.7K
Hair growth begins with the production of keratinocytes by the basal cells of the hair bulb. As new cells are deposited at the hair bulb, the hair shaft is pushed through the follicle toward the surface. Keratinization is completed as the cells are pushed to the skin surface to form the shaft of hair that is externally visible. The external hair is completely dead and composed entirely of keratin. Hair can be cut or shaven without damaging the hair structure because the cut is superficial. Most...
