Summary
Prompt diagnosis of pyoderma gangrenosum (PG) after surgery is crucial. Early treatment of this inflammatory skin condition prevents wound worsening and improves patient outcomes.
Area of Science:
- Dermatology
- Surgical Complications
- Wound Healing
Background:
- Pyoderma gangrenosum (PG) is a rare, ulcerative inflammatory neutrophilic dermatosis.
- Postoperative PG can mimic surgical site infections, delaying diagnosis and treatment.
Observation:
- A 60-year-old polytraumatized male developed PG post-stabilization surgery.
- The PG presented as a postoperative infection, causing diagnostic delay and wound progression.
Findings:
- Delayed diagnosis of PG led to significant wound deterioration.
- Appropriate treatment of PG resulted in clinical improvement and wound healing.
Implications:
- Timely identification and management of postoperative PG are essential for preventing severe morbidity.
- Multidisciplinary care, including plastic surgery for wound coverage, is vital for recovery.

Burn Injuries
3.8K
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...

Acute Pyelonephritis I: Introduction
329
Pyelonephritis is a bacterial infection that primarily affects the renal parenchyma and collecting system, including the renal pelvis, tubules, and interstitial tissue of one or both kidneys. It can be classified as either acute—a sudden, severe infection—or chronic, which refers to long-term or recurrent kidney infections.The primary cause of acute pyelonephritis (APN) is bacterial infection, with Escherichia coli accounting for approximately 70-80% of cases. Other bacteria, such...

Acute Pyelonephritis II: Diagnostic Studies and Management
197
Introduction:For diagnosing acute pyelonephritis, a comprehensive patient history is collected to identify symptoms such as dysuria, frequent or urgent urination, flank pain, or costovertebral angle (CVA) tenderness that may suggest a kidney infection.Physical ExaminationDuring the physical examination, CVA tenderness is assessed. This involves gentle percussion over the costovertebral angle, where tenderness often indicates a kidney infection.Diagnostic TestsUrinalysis: Used to identify white...
