Skin Diseases and Disorders

2.8K
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...

Asthma-I: Introduction01:29

Asthma-I: Introduction

2.6K
Asthma is a chronic respiratory ailment that requires careful management due to its varying symptoms and influencing factors. It is characterized by airway inflammation, bronchial hyperresponsiveness, and reversible airflow obstruction, leading to symptoms like wheezing, shortness of breath, chest tightness, and coughing. The symptom frequency and intensity may vary considerably over time. It is also linked to immune system responses to allergens and irritants, highlighting the complex...

Respiratory disorders encompass a range of conditions with varying levels of severity. Asthma, marked by chronic airway inflammation and hypersensitivity, is one such condition. It can lead to airway obstruction due to factors like bronchial spasms, mucosal edema, increased mucus secretion, or epithelial damage. Asthma triggers are diverse, ranging from allergens to emotional upset, and treatment focuses on both immediate relief through bronchodilators and long-term inflammation suppression.

Types of Toxins

1.6K
Humans continually engage with an environment rich in potentially harmful chemicals. These are introduced to our bodies through inhalation, ingestion, or skin contact. These chemicals exist in various forms, such as air and environmental pollutants, agricultural chemicals, organic solvents, and heavy metals.
Air pollutants, primarily gases, pose significant threats to respiratory health, leading to conditions like hypoxia, lung cancer, and in extreme cases, death.
Environmental pollutants like...

Assessment of Airway, Skin Color, and Use of Accessory Muscles

937
A thorough assessment of respiratory health is paramount in clinical settings to identify and manage respiratory distress and ensure adequate oxygenation. This article elaborates on the critical aspects of respiratory evaluation, including airway assessment, skin color examination, and the observation of accessory muscle use, which are integral to effectively diagnosing and managing patients with respiratory conditions.
Introduction
The initial evaluation of a patient's respiratory system...

Area of Science:

  • Environmental Dermatology
  • Toxicology

Background:

  • Air pollution poses significant global health risks.
  • Epidemiological data links air pollutants to inflammatory skin diseases (atopic dermatitis, psoriasis, acne), accelerated skin aging, hair loss, and skin cancer.

Purpose of the Study:

  • To review the impact of air pollution on skin health.
  • To elucidate underlying mechanisms and discuss therapeutic/cosmetic interventions.

Main Methods:

  • Literature review of epidemiological studies and mechanistic research.
  • Analysis of the role of reactive oxygen species, oxidative stress, and aryl hydrocarbon receptor signaling.
  • Examination of skin barrier disruption and inflammatory pathways.

Main Results:

  • Air pollutants induce reactive oxygen species, leading to oxidative stress.
  • The aryl hydrocarbon receptor pathway mediates pollutant effects on skin.
  • Air pollutants compromise skin barrier function and promote inflammation.

Conclusions:

  • Antioxidant and anti-inflammatory therapies are crucial.
  • Restoring skin barrier function is key to mitigating pollution's adverse skin effects.
  • Targeted interventions can protect skin health from environmental pollution.
