Skin Diseases and Disorders

3.9K
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...

Papillary Dermis01:11

Papillary Dermis

3.0K
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...

Myocarditis I: Introduction

Myocarditis is inflammation of the myocardium, which is the muscular layer of the heart.EtiologyMyocarditis has a diverse etiology, including a wide range of infectious and non-infectious causes:Infectious CausesViral: Common viruses include Coxsackie A and B, adenovirus, parvovirus B19, enteroviruses, and influenza A.Bacterial: Examples include infections caused by Streptococcus, Staphylococcus, and Mycoplasma species.Rickettsial: Infections like Rocky Mountain spotted fever can result in...

Reticular Dermis01:15

Reticular Dermis

2.6K
The papillary and reticular dermis are the two layers of the dermis. They are made of connective tissue with fibers of collagen extending from one to the other, making the border between the two somewhat indistinct. The dermal papillae extending into the epidermis belong to the papillary layer, whereas the dense collagen fiber bundles below belong to the reticular layer.
Reticular Layer
Underlying the papillary layer is the much thicker reticular layer, composed of dense, irregular connective...

Disorders of the Skeletal Muscle01:28

Disorders of the Skeletal Muscle

996
The clinical conditions affecting the skeletal muscle tissue are broadly categorized as musculoskeletal and neuromuscular disorders.
Musculoskeletal disorders
Musculoskeletal disorders involve injuries and conditions affecting the skeletal muscles and associated connective tissues. These disorders can arise from acute biomechanical stresses or chronic overuse and can occur across different age groups. Common injuries include sprains, fractures, and muscular strains, often resulting from...

Skin Cancer01:30

Skin Cancer

4.2K
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:

  • Rheumatology
  • Pediatrics
  • Immunology

Background:

  • Juvenile dermatomyositis (JDM) is a systemic autoimmune disease characterized by capillary vasculopathy.
  • It presents with proximal muscle weakness, elevated muscle enzymes, and characteristic skin manifestations like heliotrope rash and Gottron's papules.
  • Key complications include calcinosis, lipodystrophy, and osteoporosis, with complement-mediated vascular damage being a significant pathogenic mechanism.

Purpose of the Study:

  • To outline the diagnostic approaches and therapeutic strategies for Juvenile Dermatomyositis.
  • To emphasize the importance of early and aggressive treatment for improving patient outcomes.
  • To highlight the primary treatment modalities and the variable clinical course of JDM.

Main Methods:

  • Magnetic resonance imaging (MRI) is a widely utilized diagnostic tool for JDM.
  • Treatment focuses on controlling inflammatory myositis and preventing disease complications.
  • The standard therapeutic regimen involves high-dose corticosteroids combined with methotrexate.

Main Results:

  • Early and aggressive treatment of JDM is associated with a better prognosis.
  • The combination of high-dose corticosteroids and methotrexate is the established primary treatment.
  • The clinical course of JDM is highly variable among affected individuals.

Conclusions:

  • Prompt diagnosis and intervention are crucial for managing Juvenile Dermatomyositis.
  • Effective treatment strategies aim to mitigate inflammation and prevent long-term complications.
  • Understanding the variable nature of JDM is essential for personalized patient care.
