Classification of Illness01:17

Classification of Illness

9.2K
The meaning of illness is individualized to each person who experiences an alteration in health. In contrast, disease is a medical term indicating a pathological change in the structure and function of the body or mind. It is a condition that has specific symptoms and boundaries.
An illness is a response to a disease in which the person's level of functioning is changed compared with a previous level. The general classification of illness includes acute and chronic.
Acute illness is severe...

Sensory Functions of the Skin01:16

Sensory Functions of the Skin

9.1K
The skin is the largest organ of the human body and plays a crucial role in our sensory perception. It contains a vast network of sensory receptors that contribute to the skin's protective function by perceiving physical, biological, and environmental cues and generating relevant responses.
There are two main categories of receptors on the skin: capsulated and non-capsulated. The non-capsulated ones are mainly the pain receptors. The capsulated ones can be further categorized based on the...

Introduction to Sensory Receptors

8.7K
Sensory receptors are vital in our ability to perceive and interpret the world. Sensory receptors are specialized cells in the peripheral nervous system that respond to various stimuli and enable one to experience different sensations. Based on specific criteria, sensory receptors are classified into distinct types.
The first classification criterion is based on cell type, position, and function. Some receptor cells are neurons with free nerve endings, where their dendrites are embedded in the...

Classification of Epithelial Tissues: Stratified Epithelium01:29

Classification of Epithelial Tissues: Stratified Epithelium

15.2K
Stratified epithelium consists of several stacked layers of cells. They provide the durability to withstand constant physical and chemical attacks. Stratified epithelium is named after the shape of the most apical layer of cells. Stratified squamous epithelium is the most common type found in the human body. In this tissue, the apical cells are squamous, whereas the basal layer contains either columnar or cuboidal cells. The basal cells divide to form new daughter cells, which gradually become...

Classification of Epithelial Tissues: Overview

28.2K
Epithelial tissues are classified according to the shape of the cells and the number of cell layers formed. Cell shapes can be squamous (flattened and thin), cuboidal (square-like, as wide as it is tall), or columnar (rectangular, taller than it is wide). Additionally, the nucleus shape helps identify the type of epithelial cells. Squamous cells have flattened disc-shaped nuclei, cuboidal cells have spherical nuclei, and columnar cells have elongated nuclei.
Based on the number of cell layers,...

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...

Summary

Chronic pruritus, or itch, presents diversely and can lead to skin damage from scratching. The International Forum for the Study of Itch (IFSI) developed a classification system to standardize itch terminology globally.

Area of Science:

  • Dermatology
  • Clinical Medicine

Background:

  • Chronic pruritus (itch) exhibits varied presentations, occurring on normal skin or alongside dermatoses.
  • Scratching, a natural response to itch, can cause significant skin damage, altering the initial clinical presentation.

Purpose of the Study:

  • To introduce the International Forum for the Study of Itch (IFSI) classification system.
  • To standardize terminology and nomenclature for itch globally.

Main Methods:

  • Development of a standardized classification system by the IFSI.
  • Categorization of itch based on presentation and associated skin conditions.

Main Results:

  • The IFSI classification system addresses itch presentation on normal skin (Group II) and with dermatoses (Group I).

  • It acknowledges chronic scratch lesions (Group III) resulting from scratching-induced damage.
  • The system provides a harmonized global nomenclature for itch.

    • Conclusions:

    • The IFSI classification offers a standardized framework for understanding and communicating about chronic pruritus.
    • This standardization aids in clinical diagnosis, research, and management of various itch conditions.
