Summary
Sensitive skin causes unpleasant sensations due to nerve ending changes and neurogenic inflammation, affecting about 40% globally. It is not psychosomatic, though psychological effects can occur.
Area of Science:
- Dermatology and Skin Health
- Neuroscience and Sensory Perception
Background:
- Sensitive skin syndrome is characterized by stinging, burning, and pain from non-injurious stimuli.
- Affects approximately 40% of the global population.
- Previously misunderstood, it's not solely a psychosomatic disorder.
Purpose of the Study:
- To elucidate the underlying mechanisms of sensitive skin syndrome.
- To differentiate sensitive skin from psychosomatic conditions.
- To provide a scientific basis for understanding and managing sensitive skin.
Main Methods:
- Review of clinical, histologic, biochemical, and therapeutic data.
- Analysis of epidermal nerve ending function and neurogenic inflammation markers.
- Evaluation of stimuli response thresholds.
Main Results:
- Sensitive skin is linked to altered epidermal nerve endings.
- Evidence supports hyperreactivity and neurogenic inflammation as key factors.
- The condition is physiologically based, not primarily psychological.
Conclusions:
- Sensitive skin syndrome stems from neurogenic inflammation and nerve hyperreactivity.
- It is a distinct physiological condition with potential psychological impacts.
- Understanding these mechanisms is crucial for effective management.

01:30Drug Toxicity: Allergic Reactions

Drug-related allergies are immune-mediated responses triggered by the administration of pharmacological agents. These hypersensitivity reactions are classified based on the immune mechanisms involved. The four primary types—Type I, II, III, and IV—are mediated by different immunological pathways and exhibit distinct clinical manifestations.Type I Hypersensitivity/ IgE-Mediated Reactions: Immunoglobulin E (IgE) immediately mediates Type I hypersensitivity reactions. Upon initial...

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...

01:24Drug Toxicity: Risk factors
60
Adverse Drug Reactions (ADRs) are potential complications that arise during pharmacotherapy, influenced by multiple risk factors. Age plays a significant role; both neonates and the elderly are at heightened risk due to their respective immature and diminished metabolic and elimination processes. Gender also impacts ADRs, with females experiencing a 1.5 to 1.7-fold greater risk than males, which may be linked to pharmacokinetic, pharmacodynamic, and hormonal differences. Notably, neonates, the...

01:16Sensory Functions of the Skin
8.9K
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...

The first thing a clinician sees is the skin, so the examination of the skin should be part of any thorough physical examination. Most skin disorders are relatively benign, but a few, including melanomas, can be fatal if untreated. A couple of the more noticeable disorders, albinism and vitiligo, affect the appearance of the skin and its accessory organs.
Albinism
Albinism is a genetic disorder that affects (completely or partially) the coloring of skin, hair, and eyes. The defect is primarily...

01:12Local Anesthetics: Adverse Effects
906
While local anesthetics are generally safe and well-tolerated, they can occasionally cause adverse effects that vary in severity. Local anesthetics can induce toxicity at two distinct levels. They can either produce local effects through direct contact with the neural elements or be absorbed into the bloodstream from the injection site, leading to systemic effects.
Once absorbed into the systemic circulation, local anesthetics can affect the organs that depend on the functioning of sodium...
