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 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 Cancer01:30

Skin Cancer

6.5K
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...

Green Algae01:21

Green Algae

992
Green algae, also referred to as chlorophytes, are different from red algae in having the chloroplasts containing chlorophylls a and b, which give them their distinct green hue. However, they lack phycobiliproteins, preventing them from developing the red or blue-green pigmentation seen in red algae. In terms of photosynthetic pigment composition, green algae closely resemble plants and share a close evolutionary relationship with them. Taxonomically Green algae belong to Phylum Chlorophyta in...

Fungal Phylum Microsporidia01:28

Fungal Phylum Microsporidia

661
Microsporidia are a group of obligate intracellular fungi that were initially classified as protists but were later reclassified based on phylogenetic, molecular, and structural evidence linking them to the Chytridiomycota. These unicellular, non-motile organisms are highly specialized parasites that infect a wide range of animal hosts, including humans. They have evolved extensive genomic and metabolic reductions, making them highly dependent on their hosts for survival.Morphology and Genomic...

Other Algae

The group Stramenopiles include some phototrophic microorganisms. Members of this group possess flagella covered in numerous short, hairlike extensions, a feature that inspired the group's name, derived from the Latin words for "straw" and "hair." Some of the main categories of Stramenopiles include diatoms, golden algae, and brown algae.Diatoms are unicellular, photosynthetic eukaryotes, with over 200 known genera. They play a key role in the planktonic communities of both marine and...

Summary
This summary is machine-generated.

A mycid (mycid) is a fungal infection reaction, often seen as symmetrical hand rashes linked to foot fungus. Treatment involves antifungal therapy and topical steroids to reduce inflammation and itching.

Area of Science:

  • Dermatology
  • Mycology
  • Immunology

Background:

  • A mycid is defined as a hyperergic reaction to a remote localized infection without detectable fungus.
  • Dermatophytids, a type of mycid caused by dermatophytes, have specific diagnostic criteria.
  • The most common dermatophytid involves symmetrical hand dyshidrotic mycid linked to foot tinea, often by Trichophyton mentagrophytes.

Purpose of the Study:

  • To define the criteria for dermatophytids.
  • To describe the clinical presentation and management of dermatophytids.
  • To differentiate dermatophytids from drug reactions.

Main Methods:

  • Review of clinical criteria for mycid and dermatophytid diagnosis.
  • Description of common clinical presentations, including hand and scalp infections.
  • Discussion of treatment strategies, including systemic and topical therapies.

Main Results:

  • Dermatophytid criteria include proven dermatophytosis, absence of fungi in lesions, initial worsening with potent antimycotics, and clearing after sufficient treatment.
  • Dermatophytids associated with tinea capitis exhibit clinical variability and can be mistaken for drug reactions.
  • Topical antifungal and corticosteroid combinations provide rapid reduction in inflammation and pruritus, especially after systemic antifungal initiation flares.

Conclusions:

  • Dermatophytids are immune-mediated reactions to fungal infections.
  • Accurate diagnosis and differentiation from drug reactions are crucial.
  • Combined topical therapy offers effective symptom management, particularly for overtreatment flares.
