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

Accessory Structures of the Skin: Hair and Hair Follicles

5.3K
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...

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...

Accessory Structures of the Skin: Sebaceous Glands

5.1K
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...

Chronic Kidney Disease II: Clinical Manifestations

876
Chronic Kidney Disease (CKD) progressively impairs multiple body systems due to the accumulation of uremic toxins, which disrupt cellular functions across various organs.Neurologic symptomsNeurologic symptoms often arise early in CKD, as uremic toxin buildup drives changes in cognitive and motor functions. Patients frequently experience fatigue, headache, confusion, difficulty concentrating, and, in severe cases, seizures. Peripheral neuropathy commonly manifests as burning sensations in the...

Papillary Dermis01:11

Papillary Dermis

6.6K
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...

Introduction to the Integumentary System

15.8K
The integumentary system is the organ system that comprises the skin and its associated structures. It is the largest system in the human body and plays a crucial role in protecting and maintaining homeostasis. The integumentary system serves several functions including protection, regulation, sensation, and secretion.
The skin, which is the primary organ of the integumentary system, consists of three main layers: the epidermis, dermis, and hypodermis (subcutaneous tissue). The epidermis is the...

Summary
This summary is machine-generated.

Pruritus, or itching, is a common symptom linked to various skin conditions and systemic diseases. Effective treatment often requires an interdisciplinary approach beyond simple antihistamines.

Area of Science:

  • Dermatology
  • Neuroscience
  • Immunology

Background:

  • Pruritus, a superficial sensory experience, serves as a defense mechanism against environmental factors.
  • It is a common symptom in both healthy individuals and those with underlying diseases, particularly dermatoses.
  • Key mediators of pruritus include histamine, tryptase, endothelins, substance P, bradykinin, prostaglandins, and acetylcholine.

Purpose of the Study:

  • To elucidate the mechanisms underlying pruritus.
  • To identify and discuss key dermatoses and systemic diseases associated with pruritus.
  • To highlight the challenges and interdisciplinary nature of treating pruritic conditions.

Main Methods:

  • Review of existing literature on pruritus mechanisms and associated diseases.
  • Analysis of the role of various mediators in pruritus.
  • Discussion of diagnostic and therapeutic challenges in pruritic dermatoses.

Main Results:

  • Pruritus is a frequent symptom in atopic diseases like atopic dermatitis and urticaria.
  • Cutaneous T-cell lymphoma presents with early and intensifying pruritus.
  • Systemic diseases and even skin dryness or pregnancy can manifest with pruritus.

Conclusions:

  • Pruritus is a complex symptom with diverse causes, ranging from dermatological to systemic conditions.
  • Treatment of pruritic dermatoses is challenging and necessitates an interdisciplinary approach.
  • Antihistamines are not universally effective, especially in conditions like cutaneous T-cell lymphoma or liver/kidney diseases.
