Rocky Mountain Spotted Fever

Rocky Mountain Spotted Fever

Rocky Mountain Spotted Fever (RMSF) is a severe tick-borne illness caused by Rickettsia rickettsii, a Gram-negative, coccobacillary bacterium. This pathogen is an obligate intracellular parasite, requiring a host cell for replication. Transmission occurs through the bite of an infected tick. In the United States, the most important vectors are Dermacentor variabilis (American dog tick) and Dermacentor andersoni (Rocky Mountain wood tick), though other tick species may also serve as vectors.

Reticular Dermis

Reticular Dermis

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...

Photoreceptors and Plant Responses to Light

Photoreceptors and Plant Responses to Light

Light plays a significant role in regulating the growth and development of plants. In addition to providing energy for photosynthesis, light provides other important cues to regulate a range of developmental and physiological responses in plants.

Skin Diseases and Disorders

Skin Diseases and Disorders

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...

Skin Cancer

Skin Cancer

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...

Papillary Dermis

Papillary Dermis

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 and...

Summary

Plant contact can cause phototoxic dermatitis (photophytodermatitis) due to furocumarins, leading to skin lesions after sun exposure. This condition affects those working with plants, such as gardeners and florists.

Area of Science:

Dermatology
Botany
Toxicology

Background:

Plant contact can trigger phototoxic or photoallergic reactions.
Phototoxic dermatitis (photophytodermatitis) results from exposure to plants containing furocumarins (psoralens) and subsequent sun exposure.
Furocumarins, including linear psoralens (5-MOP, 8-MOP) and angular compounds like angelicin and pimpinellin, can bind to DNA, causing cellular damage.

Purpose of the Study:

To investigate phytophotodermatitis occurrences.
To highlight the role of furocoumarin-containing plants in skin reactions.
To document regional cases observed over a three-year period.

Main Methods:

Review of plant-induced phototoxic reactions.
Identification of causative plant families (Apiaceae, Rutaceae, Leguminosae, Moraceae).
Clinical observation of phytophotodermatitis cases in a specific region during spring and summer.

Main Results:

Skin lesions, including erythema, bulla formation, itch, or pain, typically appear 24-48 hours post-exposure.
Long-lasting hyperpigmentation is a common sequela.
Occupational groups like florists, gardeners, and farmers are at higher risk.

Conclusions:

Furocoumarin-rich plants pose a significant risk for phototoxic dermatitis.
Awareness and identification of these plants are crucial for prevention in at-risk professions.
Regional monitoring of phytophotodermatitis is important for public health awareness.
