Summary
Cutaneous pathomimia, a self-induced condition, was diagnosed in a young woman with chronic lip ulcerations. Early recognition and psychiatric evaluation are crucial for managing this rare dermatological disorder.
Area of Science:
- Dermatology
- Psychiatry
Background:
- Cutaneous pathomimia is a rare self-induced condition involving conscious self-injury to mucocutaneous areas.
- It often presents with chronic, non-healing lesions that can mimic other dermatological diseases.
Observation:
- A 22-year-old woman presented with a 3-month history of a painful, ulcerated lesion on her lower lip.
- Initial biopsies were non-specific, and differential diagnoses included squamous cell carcinoma and pyoderma gangrenosum.
- A second identical lesion appeared on the contralateral lip as the first healed with occlusion, coinciding with reported hand manipulation and family conflicts.
Findings:
- Psychiatric evaluation, alongside clinical and evolutionary data, confirmed the diagnosis of cutaneous pathomimia.
- The patient's self-inflicted injury pattern was identified as the cause of the recurrent lip ulcerations.
Implications:
- This case highlights the importance of considering self-inflicted conditions in the differential diagnosis of chronic lip lesions.
- Integrated dermatological and psychiatric management is essential for effective treatment and improved patient outcomes in cutaneous pathomimia.

01:28Peptic Ulcer Disease II: Pathophysiology
2.2K
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.

01:30Peptic Ulcer Disease I: Introduction
891
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...

Medical treatment strategies for peptic ulcers encompass various methods. The primary goal of treatment is to diminish gastric acidity and strengthen mucosal defense mechanisms.
The therapeutic approach involves ensuring adequate rest, implementing drug therapy, promoting smoking cessation, making dietary modifications, and emphasizing long-term follow-up care.

01:29Drugs for Treatment of Ulcerative Colitis in IBD
537
Ulcerative colitis is a chronic inflammatory condition primarily affecting the colon and rectum. The primary drugs used in the treatment of ulcerative colitis are aminosalicylates. They exhibit anti-inflammatory and immunosuppressive properties. They modulate inflammatory mediators and inhibit the activity of nuclear factor κB (NF-κB). Aminosalicylates also reduce inflammation by inhibiting prostaglandin and leukotriene production and decreasing neutrophil chemotaxis and superoxide...

Introduction
Inflammatory bowel disease, or IBD, encompasses a group of disorders characterized by chronic inflammation or ulceration of the gastrointestinal tract.
Risk Factors
The exact cause of IBD remains unclear, although it is believed to be due to a mix of genetic, environmental, microbial, and immune factors. Genetic factors are significant in determining susceptibility to IBD, with family history being a critical risk factor. Individuals with a first-degree relative who has IBD are at...

1.3K
Peptic ulcers are sores on the stomach's inner lining and the upper small intestine, which are the result of disruptions in the mucosal layer that houses parietal cells which produce gastric acid, and chief cells which secrete pepsinogen.
In the antrum region, G cells secrete the gastrin hormone that binds to gastrin-cholecystokinin-B (CCK2) receptors on parietal and enterochromaffin-like (ECL) cells in the fundic glands. Simultaneously, the vagus nerve releases acetylcholine, which binds...
