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...

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...

Fungal Phylum Ascomycota01:28

Fungal Phylum Ascomycota

2.0K
Phylum Ascomycota, a major division within the subkingdom Dikarya, comprises a diverse range of fungal species, including both unicellular yeasts and filamentous molds such as Aspergillus and Penicillium. These fungi thrive in a variety of habitats, from aquatic ecosystems to terrestrial environments, playing crucial ecological and economic roles.Morphology and ReproductionThe defining characteristic of Ascomycetes, commonly referred to as sac fungi, is the ascus—a sac-like structure that...

Fungal Group Zygomycota01:29

Fungal Group Zygomycota

1.8K
Zygomycota, previously classified as a distinct fungal group, are primarily terrestrial, saprophytic molds that play a crucial role as decomposers. Recent phylogenetic studies have revealed that these fungi are now divided into two major clades — Mucoromycota, which includes many symbiotic species, and Zoopagomycota, which primarily consists of parasitic and pathogenic fungi. These groups exhibit distinct ecological roles and reproductive strategies while sharing key structural and...

    Summary

    Dermatomycosis, fungal skin infections, were diagnosed in 72% of patients. Trichophyton species were the most common cause, particularly T. rubrum, with tinea cruris and tinea corporis being the most frequent clinical presentations.

    Area of Science:

    • Dermatology
    • Mycology
    • Infectious Diseases

    Background:

    • Dermatomycoses are common superficial fungal infections affecting the skin, hair, and nails.
    • Accurate etiological diagnosis is crucial for effective treatment and public health management of fungal infections.

    Purpose of the Study:

    • To mycologically investigate the prevalence and etiological agents of dermatomycoses in patients attending a tertiary care hospital.
    • To identify the most common fungal genera and species causing dermatomycoses and analyze their distribution across different clinical presentations and demographics.

    Main Methods:

    • A prospective study involving 300 clinically diagnosed dermatomycosis cases.
    • Mycological analysis using direct smear microscopy and fungal culture techniques.
    • Identification of isolated fungal species and correlation with clinical diagnosis and patient demographics.

    Main Results:

    • Dermatomycosis was confirmed in 216 cases (72%) through direct microscopy and/or culture.
    • Trichophyton species were the predominant isolates (79.7%), followed by Candida (13.6%), Epidermophyton (4.2%), and Microsporum (2.5%).
    • Tinea cruris in males and tinea corporis in females were the most common clinical forms; T. rubrum was the most frequently isolated species.

    Conclusions:

    • Fungal infections, particularly those caused by Trichophyton species, are highly prevalent in the studied population.
    • Clinical presentation of dermatomycosis varies by age and sex, highlighting the need for targeted diagnostic and treatment strategies.
    • The study underscores the importance of mycological investigations for accurate diagnosis and management of superficial fungal infections.
