Skin Diseases and Disorders

5.8K
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...

Inflammatory Response01:28

Inflammatory Response

17.4K
An inflammatory response is a localized, nonspecific immune reaction that occurs when a tissue is injured. It is characterized by redness, swelling, heat, and pain, which are commonly called the cardinal signs and symptoms of inflammation. Inflammation can sometimes result in a loss of function.
Inflammation can be triggered by various stimuli, such as impact, abrasion, chemical irritation, infections, and extreme hot or cold temperatures. These can damage cells and connective tissue fibers,...

Changes in Skin Color: Clinical Perspectives

3.9K
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...

Atherosclerosis III: Management

482
Management of atherosclerosis involves an integrated strategy encompassing pharmacological treatment, surgical interventions, lifestyle changes, and nutrition therapy to address the multifactorial nature of the disease.Pharmacological TherapyA cornerstone of atherosclerosis management is the use of pharmacological agents. Statins, such as atorvastatin, are pivotal in inhibiting HMG-CoA reductase, an enzyme that catalyzes an initial step in cholesterol synthesis in the liver. This reduction in...

Papillary Dermis01:11

Papillary Dermis

6.2K
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...

Peripheral Arterial Disease II: Clinical Manifestations and Diagnostic Evaluation

500
Clinical manifestationsPeripheral Arterial Disease (PAD) manifests through a range of symptoms, from the characteristic intermittent claudication to atypical presentations and severe complications in advanced stages. Intermittent claudication, a hallmark symptom of PAD, presents as exercise-induced muscle pain that typically resolves within minutes of rest. This pain is reproducible and stems from inadequate blood flow, leading to the accumulation of lactic acid produced during anaerobic...

Summary

A new proposal defines moderate psoriasis using Psoriasis Area Severity Index (PASI) and Dermatology Life Quality Index (DLQI) scores. This aims to improve psoriasis severity classification for better treatment decisions.

Area of Science:

  • Dermatology
  • Clinical assessment
  • Psoriasis research

Background:

  • The Psoriasis Area Severity Index (PASI) is standard for assessing psoriasis severity and guiding treatment.
  • Current stratification divides patients into mild and moderate-to-severe disease categories based on PASI scores.

Purpose of the Study:

  • To propose a refined definition and characterization of moderate psoriasis.
  • To integrate PASI and Dermatology Life Quality Index (DLQI) scores for a more comprehensive assessment.

Main Methods:

  • A consensus proposal was developed by 6 experienced dermatologists.
  • Methods included a critical review of existing literature and case discussions.

Main Results:

  • PASI, DLQI, and Body Surface Area (BSA) are recommended for classifying psoriasis severity (mild, moderate, severe).
  • Severity assessment should combine PASI and DLQI, with equal weighting.
  • Proposed criteria: Mild (PASI<7, DLQI<7), Moderate (PASI 7-15, DLQI 5-15, considering site/psychosocial impact), Severe (PASI >15).

Conclusions:

  • A more precise psoriasis severity classification enhances risk-benefit assessment for therapeutic decisions.
  • This refined classification aids in optimizing patient management and treatment strategies.
