Study of Dermatoglyphics in Dermatoses.

Summary
Dermatoglyphic patterns differ significantly in psoriasis and alopecia areata, with specific loop and arch variations observed in vitiligo patients. Total ridge count remained unchanged across these dermatological conditions.
Area of Science:
- Dermatology
- Genetics
- Anthropology
Background:
- Dermatoglyphics, the study of skin patterns, can offer insights into genetic predispositions.
- Previous research suggests potential links between dermatoglyphic variations and various dermatoses.
Purpose of the Study:
- To investigate dermatoglyphic pattern differences in Indian Army personnel with psoriasis, alopecia areata, and vitiligo compared to controls.
- To analyze total ridge count variations in these dermatological conditions.
Main Methods:
- A study of 100 Indian Army Personnel (25 each of controls, psoriasis, alopecia areata, vitiligo).
- Analysis of dermatoglyphic patterns (loops, whorls, arches) and total ridge count.
Main Results:
- Psoriasis showed a significant increase in loops and decrease in whorls.
- Alopecia areata exhibited a significant increase in whorls and decrease in arches.
- Vitiligo displayed a high prevalence of ulnar loops and absence of radial loops on specific digits/hands.
- Total ridge count showed no significant changes in any of the studied dermatoses.
Conclusions:
- Dermatoglyphic patterns are significantly altered in psoriasis, alopecia areata, and vitiligo.
- These findings suggest potential diagnostic or etiological links between specific dermatoglyphic variations and these skin conditions.
- Total ridge count is not a distinguishing factor for these dermatoses.

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...

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.

8.5K
The term desmosome derives from the Greek words "desmo" and "soma" meaning "adhesion bodies." This structure was first observed during the late 1800s and described as small, dense nodules in the epidermis. Desmosomes are button-like structures that help form an interlinked network of intermediate filaments across the cells. These junctions are essential to hold cells together under mechanical stress and to maintain tissue integrity. Desmosomes are multi-protein...

01:21Accessory Structures of the Skin: Sebaceous Glands
5.0K
A sebaceous gland is a type of oil gland found almost all over the skin ( except palms and soles) and helps lubricate and waterproof the skin and hair. Most sebaceous glands are associated with hair follicles. They generate and excrete sebum, a mixture of lipids, onto the skin surface, thereby naturally lubricating the dry and dead layer of keratinized cells of the stratum corneum, keeping it pliable.
These glands that produce the oils on the skin and hair are holocrine glands. The mature...

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...
