Skin Diseases and Disorders

6.3K
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...

Changes in Skin Color: Clinical Perspectives

4.2K
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...

Clinical Applications of Epidermal Stem Cells01:19

Clinical Applications of Epidermal Stem Cells

3.4K
Epidermal stem cells (EpiSCs) are mainly located at the basal layer of the epidermis. These cells repair minor injuries of the skin and replace dead skin cells. However, EpiSCs’ cannot heal severe wounds such as major burns or those from diabetes or hereditary disorders. In such cases, culturing the epidermal stem cells from the patient is possible and has yielded successful treatment options, such as laboratory-grown skin grafts. These grafts are synthesized using a patient’s own...

Antiasthma Drugs: Leukotriene Modifiers01:19

Antiasthma Drugs: Leukotriene Modifiers

2.3K
Leukotriene modifiers, or cysteinyl leukotriene receptor antagonists, are medications used to manage chronic asthma. These agents target specific inflammatory mediators produced during arachidonic acid metabolism, an essential process in generating inflammation in the body.
Leukotriene modifiers work through two distinct mechanisms:

Reticular Dermis01:15

Reticular Dermis

5.6K
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...

Staphylococcal Skin Infections01:29

Staphylococcal Skin Infections

110
Staphylococcus aureus is a Gram-positive coccus that resides harmlessly on the skin and mucous membranes of healthy individuals. When the skin barrier is breached, it can shift from a commensal to an opportunistic pathogen. This transition is facilitated by surface adhesins, such as clumping factor B and S. aureus surface protein G (SasG), which bind to structural proteins, including loricrin and cytokeratin, in the damaged epidermis. Protein A, another key factor, binds the Fc region of...

Summary
This summary is machine-generated.

Atopic dermatitis (AD) patients with leukoderma showed higher disease severity and prurigo lesions. These findings suggest a distinct immune profile in AD patients with concurrent leukoderma, potentially linked to inflammation.

Area of Science:

  • Dermatology
  • Immunology

Background:

  • Atopic dermatitis (AD) can co-occur with vitiligo, but the incidence and characteristics of this association are not well understood.
  • Investigating leukoderma in AD is crucial due to its occasional link with inflammation within AD lesions.

Purpose of the Study:

  • To prospectively investigate the clinical manifestations and bioparameters of atopic dermatitis (AD) associated with leukoderma.
  • To identify specific characteristics of AD in patients who also present with leukoderma.

Main Methods:

  • A prospective observational study involving 52 atopic dermatitis (AD) patients followed in an outpatient clinic.
  • Patients were assessed for the presence of leukoderma, with 8 patients (15.4%) forming the leukoderma group and 44 the non-leukoderma group.

Main Results:

  • The leukoderma group exhibited a significant female preponderance.
  • Leukoderma patients tended to have higher SCORAD (Severity of Atopic Dermatitis) scores, CCL17 levels, and lactate dehydrogenase.
  • The leukoderma group showed a lower incidence of allergic rhinitis but a higher frequency of prurigo lesions.

Conclusions:

  • Atopic dermatitis with leukoderma is associated with increased disease severity and specific clinical features like prurigo lesions.
  • These patients may have a distinct immune response, potentially a T-helper 1-skewing state, contributing to leukoderma development.
  • The reduced association with allergic rhinitis in the leukoderma group suggests a different immunological profile compared to AD without leukoderma.
