Summary
Serious skin adverse reactions (SCARs) are rare but life-threatening drug eruptions. This review focuses on Stevens-Johnson syndrome/toxic epidermal necrolysis (SJS-TEN), DRESS syndrome, and acute generalized exanthematous pustulosis (AGEP).
Area of Science:
- Dermatology
- Pharmacology
- Toxicology
Background:
- Drug eruptions vary widely in frequency and clinical course.
- Serious Cutaneous Adverse Reactions (SCARs) represent a critical subset of drug reactions.
- SCAR syndromes, though rare, carry significant morbidity and mortality.
Purpose of the Study:
- To review and differentiate key SCAR syndromes.
- To highlight the distinct clinical entities within SCARs.
- To emphasize the importance of recognizing these severe drug reactions.
Main Methods:
- Literature review of SCAR syndromes.
- Comparative analysis of SJS-TEN, DRESS, and AGEP.
- Synthesis of current understanding of these conditions.
Main Results:
- Identified three primary SCAR syndromes: SJS-TEN, DRESS, and AGEP.
- Distinguished these syndromes based on clinical presentation and prognosis.
- Emphasized the severity and potential fatality of these reactions.
Conclusions:
- Stevens-Johnson syndrome/toxic epidermal necrolysis (SJS-TEN), DRESS, and AGEP are distinct, severe drug reactions.
- Prompt recognition and management are crucial for improving patient outcomes.
- Understanding these syndromes is vital for clinicians managing drug-induced skin conditions.

01:30Skin Cancer
6.2K
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.

01:19Clinical Applications of Epidermal Stem Cells
3.3K
Epidermal stem cells (EpiSCs) are mainly located at the basal layer of the epidermis. These cells repair minor injuries of the skin and replace dead skin cells. However, EpiSCs’ cannot heal severe wounds such as major burns or those from diabetes or hereditary disorders. In such cases, culturing the epidermal stem cells from the patient is possible and has yielded successful treatment options, such as laboratory-grown skin grafts. These grafts are synthesized using a patient’s own...

5.8K
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...

01:25Cardiomyopathy I: Introduction and Classification
654
Cardiomyopathy, or CMP, is a group of diseases affecting the myocardial structure, impairing its ability to pump blood effectively. This condition can lead to arrhythmias, heart failure, or sudden cardiac death.Cardiomyopathies are classified into primary and secondary categories:Primary Cardiomyopathy refers to conditions involving only the heart muscle that are often idiopathic (of unknown cause) or genetic. They primarily affect the myocardium without the involvement of other systemic...

Rheumatic heart disease or RHD is a chronic condition that results from rheumatic fever, causing permanent damage to the heart valves.Etiology and Risk FactorsIt primarily arises from rheumatic fever, an inflammatory disease that can develop after untreated or inadequately treated group A streptococcal (GAS) pharyngitis. Streptococcus spreads through direct contact with oral or respiratory secretions. While the bacteria are the causative agents, factors like malnutrition, overcrowding, poor...

01:30Aneurysm I: Introduction
489
An aortic aneurysm is a localized outpouching or dilation at a weak point in the artery wall. It may involve different parts of the aorta, such as the abdominal aorta, aortic arch, or thoracic aorta.Etiological factorsSeveral disorders are associated with aortic aneurysms.Congenital causes, such as primary connective tissue disorders like Marfan syndrome, impact the integrity and strength of connective tissues, notably affecting the aorta. Marfan syndrome is a genetic disorder that specifically...
