Skin Diseases and Disorders

6.1K
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...

Skin Cancer01:30

Skin Cancer

6.6K
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...

Hypersensitivities

8.3K
Hypersensitivity, also known as a hypersensitivity reaction or allergic reaction, is a condition where the body's immune system reacts abnormally to a foreign substance. Such substances, that cause hypersensitivity are referred to as an allergen, could be something typically harmless to most people, like pollen or certain foods.
Types of Hypersensitivities
Hypersensitivity reactions are categorized into four types: Type 1, Type 2, Type 3, and Type 4. Each type has a distinct mechanism...

Hand hygiene01:23

Hand hygiene

6.5K
Asepsis is the practice of preventing or breaking the chain of infection. The nurse employs aseptic techniques to prevent the spread of microorganisms and reduce the risk of diseases. Hand hygiene is the cornerstone of aseptic techniques and is classified into medical and surgical asepsis. Medical asepsis includes hand hygiene and the use of gloves. Surgical asepsis, or the sterile technique, refers to practices that render and keep objects and areas free of microorganisms.

Inflammatory Bowel Disease III: Diagnostic Studies and Management I-Nutritional Therapy

1.0K
Various diagnostic tests are employed in the diagnostic process for Inflammatory Bowel Disease (IBD), particularly to differentiate between Crohn's disease and ulcerative colitis.
Diagnostic studies
A colonoscopy is the definitive screening test, distinguishing ulcerative colitis from other colon diseases with similar symptoms. During a colonoscopy test, inflamed mucosa with exudate ulcerations can be observed, and biopsies are taken to determine the histologic characteristics of the...

Changes in Skin Color: Clinical Perspectives

4.1K
The first thing a clinician sees is the skin, so the examination of the skin should be part of any thorough physical examination. Most skin disorders are relatively benign, but a few, including melanomas, can be fatal if untreated. A couple of the more noticeable disorders, albinism and vitiligo, affect the appearance of the skin and its accessory organs.
Albinism
Albinism is a genetic disorder that affects (completely or partially) the coloring of skin, hair, and eyes. The defect is primarily...

Summary

Hand dermatitis is complex, influenced by genetics and exposure. Identifying and removing triggers, alongside graded therapy, is key for effective treatment and management.

Area of Science:

  • Dermatology
  • Occupational Health
  • Immunology

Background:

  • Hand dermatitis pathogenesis is multifactorial, involving genetic predisposition and environmental exposures.
  • High incidence is linked to female gender, contact allergy, atopic dermatitis, and wet work.
  • Risk factors for persistence include extent, allergic/atopic etiology, childhood dermatitis, and early onset.

Purpose of the Study:

  • To outline the multifactorial nature of hand dermatitis.
  • To emphasize diagnostic workup, including occupational and recreational exposure assessment.
  • To highlight the importance of trigger identification and tailored treatment strategies.

Main Methods:

  • Detailed assessment of occupational and recreational exposure for diagnosis.
  • Patch testing for patients with persistent hand dermatitis (>3 months).
  • Graded therapy based on clinical severity and validated instruments for monitoring.

Main Results:

  • Contact allergen exposure contributes to half of all hand dermatitis cases.
  • Early onset (before 20) is a significant risk factor for persistence.
  • Cost of illness is comparable to moderate to severe psoriasis.

Conclusions:

  • Effective hand dermatitis management requires identifying and eliminating individual triggers.
  • Substitution of identified allergens/irritants and preventive measures are crucial.
  • Graded, severity-adjusted therapy is essential for successful and sustainable treatment.
