Skin Diseases and Disorders

4.1K
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...

Accessory Structures of the Skin: Sebaceous Glands

2.2K
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...

Restless Leg Syndrome and Night Terrors

245
Restless Leg Syndrome (RLS), also known as Willis-Ekbom disease, is a neurological disorder characterized by an uncontrollable urge to move the legs due to uncomfortable sensations. These sensations typically occur during periods of rest or inactivity, particularly when lying down or sitting, and can severely disrupt sleep.
The exact cause of RLS is not fully understood, but it is believed to involve dopamine, a neurotransmitter that helps regulate muscle movement. Imbalances in dopamine levels...

Accessory Structures of the Skin: Hair and Hair Follicles

2.6K
Hair and hair follicles are integral components of the integumentary system. Hair is a filamentous structure composed mainly of a protein called keratin. It is found on the surface of the skin throughout the body, except for areas such as the palms of the hands and soles of the feet.
Hair is a keratinous filament growing out of the epidermis. It is primarily made of dead, keratinized cells. Hair strands originate at the epidermal penetration called the hair follicle. The hair shaft is the part...

Skin Cancer01:30

Skin Cancer

4.5K
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...

Introduction to the Integumentary System

9.4K
The integumentary system is the organ system that comprises the skin and its associated structures. It is the largest system in the human body and plays a crucial role in protecting and maintaining homeostasis. The integumentary system serves several functions including protection, regulation, sensation, and secretion.
The skin, which is the primary organ of the integumentary system, consists of three main layers: the epidermis, dermis, and hypodermis (subcutaneous tissue). The epidermis is the...

Area of Science:

  • Dermatology
  • Infectious Diseases
  • Epidemiology

Background:

  • Scabies is a highly contagious ectoparasitic infection caused by the mite Sarcoptes scabiei.
  • It disproportionately affects vulnerable populations, including children, the elderly, and immunocompromised individuals.
  • Conventional understanding links scabies prevalence to low socioeconomic status and developing regions.

Observation:

  • A case of scabies was identified in a tertiary care hospital in North America.
  • This presentation occurred in a setting not typically associated with high scabies prevalence.
  • The diagnosis necessitated treatment for the patient and all household contacts.

Findings:

  • The case challenges the traditional epidemiological view of scabies.
  • It underscores the importance of considering scabies in diverse clinical settings.
  • Prompt diagnosis and treatment are crucial to prevent further transmission.

Implications:

  • This case suggests a broader distribution of scabies than previously recognized in developed nations.
  • It highlights the need for increased awareness among healthcare providers in North America.
  • Further research may be warranted to understand the evolving epidemiology of scabies.
