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...

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...

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...

Skin Cancer01:30

Skin Cancer

6.4K
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.
Basal Cell Carcinoma (BCC): BCC is the most common type of skin cancer, accounting for about 80% of cases. It typically develops in...

Accessory Structures of the Skin: Nails01:05

Accessory Structures of the Skin: Nails

3.8K
Nails are one of the important accessory structures of the skin. They are hard, protective structures that cover the dorsal surface of the distal phalanges of fingers and toes. Nails are composed of specialized keratinized cells and serve various functions, including protection, sensation, and manual dexterity.
The main components of a nail include the following.
Nail Plate: The nail plate is the visible portion of the nail that extends beyond the fingertips or toes. It is a hard, translucent...

    Summary
    This summary is machine-generated.

    Dermatoglyphic analysis reveals distinct fingerprint patterns in psoriasis patients. Psoriatic females showed more whorl patterns, while males had a decreased total ridge count compared to controls.

    Area of Science:

    • Dermatology
    • Genetics
    • Human Biology

    Background:

    • Psoriasis is a chronic inflammatory skin condition.
    • Dermatoglyphics, the study of fingerprint patterns, can offer insights into genetic predispositions.
    • Previous research suggests potential links between dermatoglyphic variations and various diseases.

    Purpose of the Study:

    • To investigate dermatoglyphic differences between individuals with psoriasis and healthy controls.
    • To identify specific fingerprint pattern variations associated with psoriasis.
    • To explore potential sex-based differences in these dermatoglyphic associations.

    Main Methods:

    • Dermatoglyphic analysis was performed on 40 cases of psoriasis and 40 age- and sex-matched controls.
    • Fingerprint patterns (arch, loop, whorl) were analyzed for each digit.
    • Total ridge count was calculated for each individual.

    Main Results:

    • Control subjects lacked arch patterns on the 4th and 5th fingers.
    • Psoriatic females exhibited an increased incidence of whorl patterns.
    • Psoriatic males showed a decreased total ridge count; whorl patterns were more prevalent on the 4th finger and the right hand in psoriatic cases.

    Conclusions:

    • Specific dermatoglyphic patterns, particularly whorl prevalence and total ridge count, may be associated with psoriasis.
    • Sex-specific differences in dermatoglyphic patterns related to psoriasis were observed.
    • Dermatoglyphics could serve as a potential, non-invasive marker for studying psoriasis.
