Papillary Dermis01:11

Papillary Dermis

4.0K
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...

Endoscopic Studies I: Bronchoscopy and Thoracoscopy

290
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...

Confocal Fluorescence Microscopy01:16

Confocal Fluorescence Microscopy

15.9K
Confocal microscopy is an advanced microscopic technique. The prime advantage of the confocal microscope over other microscopy techniques is its ability to block the out-of-focus light from the illuminated samples using pinholes. It is widely used with fluorescence optics to obtain high-resolution, sharp contrast images. Unlike optical microscopes, confocal microscopes use a focused beam of light laser to scan the entire sample surface at different z-planes. These microscopes are, therefore,...

Primary Healthcare Services

1.6K
Primary care promotes wellness and prevents disease. This care includes health promotion, education, protection (such as immunizations), early disease screening, and environmental considerations. Settings providing this type of healthcare include physician offices, public health clinics, school nursing, and community health nursing.
In 1978, international leaders convened in Alma-Ata, Kazakhstan, for what would be a pivotal event in global health. The Alma-Ata Declaration was the first to call...

Secondary Healthcare System01:11

Secondary Healthcare System

1.7K
Secondary healthcare is offered by a specialist, generally in hospitals or clinics for patients referred by primary healthcare providers. It occurs when a person has an illness or injury that requires specific medical care. Secondary care is often referred to as acute care. Secondary care can range from uncomplicated care to repair a minor laceration or treat a strep throat infection to more complicated emergent care, such as treating a head injury sustained in an automobile accident. Whatever...

Skin Cancer01:30

Skin Cancer

4.8K
Skin cancer is a type of cancer that occurs when there is an abnormal growth of skin cells, usually triggered by damage to the DNA within the skin cells. It is primarily caused by exposure to ultraviolet (UV) radiation from the sun or artificial sources like tanning beds. Skin cancer is the most common type of cancer worldwide, and its incidence continues to rise.
Basal Cell Carcinoma (BCC): BCC is the most common type of skin cancer, accounting for about 80% of cases. It typically develops in...

Area of Science:

  • Dermatology
  • Medical Imaging

Background:

  • Dermoscopy provides in vivo magnification of skin structures.
  • It visualizes microscopic features not visible to the naked eye.
  • It is an adjunct, not a replacement, for biopsy and histopathology.

Purpose of the Study:

  • To evaluate the impact of dermoscopy training on the diagnostic accuracy of cutaneous lesions.
  • To assess the utility of dermoscopy in clinical practice for family medicine physicians.

Main Methods:

  • Noninvasive in vivo magnification of skin structures using dermoscopy.
  • Comparison of diagnostic accuracy with and without dermoscopy.
  • Assessment of diagnostic sensitivity and specificity for cutaneous lesions.

Main Results:

  • Dermoscopy significantly increases diagnostic sensitivity compared to naked eye examination.
  • Family medicine physicians showed improved diagnostic accuracy for benign and malignant lesions after introductory dermoscopy training.

Conclusions:

  • Dermoscopy is a valuable tool for enhancing the diagnostic accuracy of skin lesions.
  • Training in dermoscopy can significantly improve the clinical performance of primary care physicians in dermatology.
