Summary
Pyoderma gangrenosum requires prompt diagnosis and treatment to prevent severe outcomes. This review offers updated diagnostic criteria and summarizes evidence for treatments, from local immunosuppression to systemic therapies for severe cases.
Area of Science:
- Dermatology
- Immunology
Background:
- Pyoderma gangrenosum presents significant diagnostic and therapeutic challenges.
- Delayed or incorrect diagnosis can lead to severe morbidity and mortality.
Purpose of the Study:
- To present novel diagnostic criteria for Pyoderma gangrenosum.
- To review and summarize evidence for various treatment modalities.
Main Methods:
- Literature review of diagnostic criteria.
- Systematic summary of treatment evidence.
Main Results:
- New diagnostic criteria are proposed to facilitate diagnosis.
- Evidence supports local immunosuppression for mild disease.
- Systemic treatments including corticosteroids, ciclosporin, and TNF-alpha inhibitors are indicated for severe cases.
Conclusions:
- Accurate and timely diagnosis is crucial for Pyoderma gangrenosum management.
- Treatment strategies vary based on disease severity, with emerging biologic options.

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...

01:30Peripheral Artery Disease I: Introduction
127
Peripheral artery disease (PAD) predominantly results from atherosclerosis, which involves the accumulation of fatty deposits, or plaques, within the walls of arteries. This causes them to narrow and harden, significantly reducing blood flow. PAD predominantly affects the legs, particularly the arteries supplying the thighs and calves. In rare cases, it may involve other arteries, including those in the arms.Etiology of PAD:The principal cause of PAD is atherosclerosis, which results from fatty...

Burn injuries occur when the skin and underlying tissues are damaged due to exposure to heat, electricity, chemicals, radiation, or friction. They can vary in severity, from minor superficial burns to severe deep burns that can be life-threatening.
The damage results in the death of skin cells, which can lead to a massive loss of fluid. Dehydration, electrolyte imbalance, and renal and circulatory failure follow, which can be fatal. Burn patients are treated with intravenous fluids to offset...

01:23Gastritis III: Clinical Manifestations and Management
665
The clinical manifestations of gastritis can vary depending on the cause and type of gastritis, but some common symptoms may include the following.
Clinical manifestations of acute gastritis
The patient with acute gastritis may have a rapid onset of symptoms, such as epigastric pain or discomfort, dyspepsia, anorexia, hiccups, or nausea and vomiting, which can last from a few hours to a few days. Erosive or hemorrhagic gastritis may cause bleeding, which may manifest as blood in vomit or as...

01:30Skin Cancer
5.0K
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.
