Breathing01:05

Breathing

60.0K
The process of breathing, inhaling and exhaling, involves the coordinated movement of the chest wall, the lungs, and the muscles that move them. Two muscle groups with important roles in breathing are the diaphragm, located directly below the lungs, and the intercostal muscles, which lie between the ribs. When the diaphragm contracts, it moves downward, increasing the volume of the thoracic cavity and creating more room for the lungs to expand. When the intercostal muscles contract, the ribs...

Upper Respiratory Drugs: Antitussives, Expectorants, and Mucolytics01:23

Upper Respiratory Drugs: Antitussives, Expectorants, and Mucolytics

368
Respiratory symptoms, such as congestion and cough, commonly accompany respiratory tract conditions. Various medications, such as antitussives, expectorants, and mucolytics, play crucial roles in providing relief.
Antitussives include codeine, dextromethorphan (Robitussin), and benzonatate (Tessalon). Codeine and dextromethorphan exert their effects centrally by suppressing the cough reflex center in the medulla.  Benzonatate operates peripherally within the respiratory tract by...

Asthma-I: Introduction

2.7K
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...

Antiasthma Drugs: Leukotriene Modifiers

394
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:

Factors Affecting Pulmonary Ventilation01:19

Factors Affecting Pulmonary Ventilation

1.5K
Besides the pressure difference between the external environment and the lungs, the airflow rate and ease of pulmonary ventilation are also influenced by three other factors: surface tension of the fluid in the alveoli, compliance of the lungs, and airway resistance.
Alveolar Surface Tension
The alveolar fluid lines the luminal surface of the alveoli and exerts a force called surface tension. This force is caused by the polar water molecules in the liquid being more strongly attracted to each...

Pulmonary Cycle: Exhalation01:17

Pulmonary Cycle: Exhalation

1.7K
In terms of human respiration, the act of expelling air, known as exhalation (or expiration), operates on the principle of pressure gradients. During expiration, the pressure within the lungs exceeds that of the surrounding atmosphere. Under normal conditions, quiet breathing involves passive exhalation and is free of muscular contractions. This is because the exhalation process is driven by the natural elastic recoil of the lungs and chest wall, both of which have an inherent tendency to...

Summary

Surfactants, used in cleaning and cosmetics, can damage the skin barrier. Newer surfactants may cause allergic contact dermatitis, requiring awareness during exposure.

Area of Science:

  • Dermatology
  • Cosmetic Science
  • Toxicology

Background:

  • Surfactants are amphipathic molecules with hydrophobic and hydrophilic components.
  • They are widely used in household, cosmetic, and medical applications for their cleansing properties.
  • On skin, surfactants reduce surface tension, aiding in the removal of sebum and dirt, but can compromise the skin barrier.

Purpose of the Study:

  • To highlight the potential of surfactants to cause skin irritation and allergic contact dermatitis.
  • To emphasize the need for increased awareness regarding the allergic potential of novel surfactant compounds.
  • To inform healthcare professionals and consumers about surfactant-induced contact allergies.

Main Methods:

  • Review of existing literature on surfactant properties and dermatological effects.
  • Analysis of the mechanisms by which surfactants interact with the stratum corneum.
  • Examination of case studies and research on novel surfactant-induced allergic contact dermatitis.

Main Results:

  • Surfactants effectively remove skin debris but can disrupt the skin barrier.
  • While irritation is a known risk, novel surfactants present a significant potential for allergic contact dermatitis.
  • First-generation surfactants, like sodium lauryl sulfate, are being replaced by newer compounds with different allergenic profiles.

Conclusions:

  • The potential for surfactants to cause allergic contact dermatitis is a growing concern.
  • Increased knowledge and vigilance are necessary to identify and manage surfactant-induced contact allergies.
  • Consideration of surfactant exposure is crucial when diagnosing and treating dermatitis.
