Endoscopic Studies I: Bronchoscopy and Thoracoscopy01:30

Endoscopic Studies I: Bronchoscopy and Thoracoscopy

Endoscopy is a non-surgical medical technique used to examine a person's internal organs and vessels. This lesson will focus on two types of endoscopic studies: bronchoscopy and thoracoscopy.
Bronchoscopy
Description
Bronchoscopy is a procedure that involves direct visualization of the larynx, trachea, and bronchi for diagnostic and therapeutic purposes. A flexible fiber optic or rigid bronchoscope is used to carry out the procedure. The fiber-optic bronchoscope is more frequently used due to...
Tracheostomy Suctioning II: Procedure01:23

Tracheostomy Suctioning II: Procedure

Tracheostomy suctioning is a vital nursing procedure that involves removing secretions from the tracheostomy tube to maintain airway patency and prevent respiratory complications. Nurses need to understand the proper technique for tracheostomy suctioning to ensure patient safety and comfort. In this guide, we will outline the step-by-step process for performing tracheostomy suctioning, including preparing the sterile field, donning personal protective equipment (PPE), lubricating and connecting...

Tracheostomy Care II: Procedure

Tracheostomy care is an essential nursing skill that involves cleaning and maintaining a tracheostomy tube to prevent infection and other complications. Here's a step-by-step guide explaining each procedure with its rationale. Note that disposable gloves are to be worn at all times and changed as often as needed to maintain a sterile work environment, and to protect both patient and healthcare worker.
Step 1: Perform hand hygiene, and put on personal protective equipment: gown, gloves, mask and...
Trachea01:22

Trachea

The trachea, commonly known as the windpipe, is a vital part of the human respiratory system. It serves as a passageway for air to travel between the larynx and the bronchi, allowing oxygen to reach the lungs. Let's explore its anatomical features, dimensions, layers of the tracheal wall, associated muscles, and the functions of its parts.
Anatomical Features:
Location: About half of the trachea is situated in the neck, anterior to the esophagus, and extends from the larynx (at the level of the...
Imaging Studies III: Gastrointestinal Motility Studies and Virtual Colonoscopy01:26

Imaging Studies III: Gastrointestinal Motility Studies and Virtual Colonoscopy

This lesson explores three gastrointestinal imaging techniques: radionuclide testing, colonic transit studies, and virtual colonoscopy.
Radionuclide Testing
Radionuclide testing is a sophisticated medical technique for assessing gastrointestinal motility. It focuses on gastric emptying and colonic transit time. Radioactive markers track the movement of food through the digestive system, providing insights into gastrointestinal disorders.
In gastric emptying studies, a meal's liquid and solid...

Area of Science:

  • Dermatology
  • Dermatopathology
  • Medical Imaging

Background:

  • Trichoscopy (hair and scalp dermoscopy) is an increasingly popular, non-invasive diagnostic tool.
  • It offers valuable insights into the differential diagnosis of numerous hair and scalp disorders.
  • Existing diagnostic frameworks can be enhanced by standardized trichoscopic evaluations.

Purpose of the Study:

  • To detail the application of trichoscopy in the differential diagnosis of common hair and scalp diseases encountered in dermatologic practice.
  • To briefly review the utility of trichoscopy in identifying genetic hair shaft abnormalities.
  • To introduce a novel classification system for perifollicular and interfollicular skin surface abnormalities observed during trichoscopy.

Main Methods:

  • Utilizing handheld dermoscopes and digital videodermoscopy systems for in-office hair and scalp examinations.
  • Systematic review of trichoscopic features associated with frequent hair and scalp pathologies.
  • Development and proposal of a new classification for perifollicular and interfollicular scalp surface abnormalities.

Main Results:

  • Trichoscopy effectively aids in the differential diagnosis of diverse hair and scalp conditions.
  • Specific trichoscopic patterns correlate with various genetic hair shaft abnormalities.
  • A new classification system for perifollicular and interfollicular skin surface abnormalities was proposed, enhancing diagnostic precision.

Conclusions:

  • Trichoscopy is a valuable and accessible technique for diagnosing hair and scalp diseases in clinical dermatology.
  • The proposed classification system offers a structured approach to analyzing scalp surface abnormalities, improving diagnostic accuracy.
  • Further research validating this classification is warranted to standardize trichoscopic interpretation.
