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...

Papillary Dermis01:11

Papillary Dermis

6.5K
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...

Reticular Dermis01:15

Reticular Dermis

5.3K
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...

Hand hygiene

6.4K
Asepsis is the practice of preventing or breaking the chain of infection. The nurse employs aseptic techniques to prevent the spread of microorganisms and reduce the risk of diseases. Hand hygiene is the cornerstone of aseptic techniques and is classified into medical and surgical asepsis. Medical asepsis includes hand hygiene and the use of gloves. Surgical asepsis, or the sterile technique, refers to practices that render and keep objects and areas free of microorganisms.

Allergic Drug Reactions01:27

Allergic Drug Reactions

1.5K
Allergic reactions related to drugs are hypersensitivity responses driven by the immune system and bear no connection to the drug's therapeutic action. While drugs in isolation do not trigger an immune response, they can interact with endogenous proteins to form antigens. These antigens stimulate lymphocytes to produce antibodies. IgE-type antibodies attach themselves to mast cells. Upon subsequent exposure to the same stimulus, the antigen-antibody interaction is initiated, unleashing...

    Summary
    This summary is machine-generated.

    This study identified common causes of allergic contact dermatitis. Cement, metals, and footwear were significant triggers, with potassium dichromate sensitivity frequently linked to cement and metal exposure.

    Area of Science:

    • Dermatology
    • Allergology
    • Occupational Health

    Background:

    • Allergic contact dermatitis (ACD) is a prevalent skin condition.
    • Identifying causative agents is crucial for effective management.
    • Occupational and environmental exposures are key factors in ACD.

    Purpose of the Study:

    • To investigate the primary causes of dermatitis in a patient cohort.
    • To determine the prevalence of positive patch tests to specific allergens.
    • To identify the sources of chromate sensitivity.

    Main Methods:

    • Patch testing was performed on 100 patients.
    • Patient demographics and occupational data were collected.
    • Allergen sources, including cement, metals, and footwear, were analyzed.

    Main Results:

    • Cement (24), metals (22), and footwear (14) were the most frequent causes of dermatitis.
    • Fifty-one patients had positive patch tests, with potassium dichromate being a common sensitizer.
    • Chromate sensitivity originated from cement (47.03%) and metals in apparel (33.32%).

    Conclusions:

    • Cement and metals are significant sources of chromate sensitivity.
    • Occupational exposures, particularly in skilled and manual laborers, contribute to dermatitis.
    • Awareness of these common allergens is vital for prevention and treatment strategies.
