Summary
Endemic pemphigus foliaceus (EPF) autoantigens vary geographically, with desmogleins implicated in most cases. Further research is needed to fully understand EPF
Area of Science:
- Dermatology
- Immunology
- Genetics
Background:
- Endemic pemphigus foliaceus (EPF) is an autoimmune blistering disease with distinct geographic foci.
- EPF predominantly affects young Amerindians in Central and South America, with specific variants in Colombia and Tunisia.
- Demographic variations exist, including age and sex predilections in different EPF foci.
Purpose of the Study:
- To review and synthesize current knowledge on autoantigens in EPF.
- To summarize immunologic and genetic findings across various EPF populations.
- To compare the characteristics of different geographic variants of EPF.
Main Methods:
- Retrospective literature review.
- Compilation and comparison of data from multiple geographic foci of EPF.
- Analysis of reported autoantigens and immunologic/genetic studies.
Main Results:
- Desmogleins are primary autoantigens in Tunisian and most American EPF cases.
- El Bagre-EPF involves plakins and desmogleins.
- Antibody-mediated immune response is the principal pathophysiology in all EPF variants.
Conclusions:
- Genetic susceptibility likely plays a role in EPF development.
- Specific causative genes for EPF remain unconfirmed.
- Further immunological and genetic investigations are essential to fully characterize EPF.

Endocarditis II: Clinical Features of Infective Endocarditis
Endocarditis can present various clinical features depending on the causative organism and the patient's underlying health conditions. Initially, the clinical features of infective endocarditis develop gradually, presenting with nonspecific symptoms that can be easily mistaken for other illnesses.General SymptomsEarly symptoms of infective endocarditis are fever, chills, weakness, malaise, fatigue, and weight loss. These symptoms reflect the systemic nature of the infection and the body's...
Peptic Ulcer Disease II: Pathophysiology
Peptic ulcer disease develops when protective mechanisms of the gastrointestinal mucosa are overwhelmed by harmful factors, leading to localized erosions in the stomach or proximal duodenum. The main causes are Helicobacter pylori infection and chronic use of nonsteroidal anti-inflammatory drugs (NSAIDs).Helicobacter pylori–Induced InjuryBacterial Adaptation and Colonization:H. pylori is a spiral, Gram-negative bacterium adapted to the acidic stomach. and transmitted through oral-oral or...
Peptic Ulcer Disease II: Pathophysiology
Peptic Ulcer Disease (PUD) is characterized by the development of ulcers in the stomach or duodenal mucosa. Its pathophysiology is complex, involving a balance between damaging and protective elements.
Damaging agents such as Helicobacter pylori, gastric acid, pepsin, and nonsteroidal anti-inflammatory drugs (NSAIDs) can weaken the mucosal defense, allowing hydrogen ions to infiltrate back and harm epithelial cells.

Skin Diseases and Disorders
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...

Peptic Ulcer Disease I: Introduction
Peptic Ulcer Disease (PUD) is characterized by mucosal excavation in the esophagus, stomach, pylorus, or duodenum. It can manifest as acute or chronic based on the extent and duration of mucosal involvement.
An acute ulcer, marked by superficial erosion and minimal inflammation, swiftly resolves upon identifying and addressing the underlying cause. In contrast, a chronic ulcer persists, potentially eroding through the muscular wall and forming fibrous tissue.
Peptic ulcers can also be...

Chronic Obstructive Pulmonary Disease II: Emphysema
Emphysema, a major phenotype of chronic obstructive pulmonary disease (COPD), is characterized by irreversible destruction of alveolar walls and permanent enlargement of distal airspaces. Unlike chronic bronchitis, which primarily affects the airways, emphysema predominantly involves the lung parenchyma, where structural damage leads to airflow limitation.PathophysiologyIt most commonly results from prolonged exposure to cigarette smoke and other toxic gases, particularly cigarette smoke.
