Summary
Chronic ulcerative stomatitis (CUS) is a rare oral condition affecting middle-aged women. Diagnosis requires biopsy and immunofluorescence, as treatments like hydroxychloroquine are more effective than glucocorticoids.
Area of Science:
- Oral pathology
- Immunodermatology
- Autoimmune diseases
Background:
- Chronic ulcerative stomatitis (CUS) is a distinct oral condition.
- Characterized by painful erosions and ulcerations.
- Histopathology often mimics oral lichen planus (OLP).
Purpose of the Study:
- To describe the immunopathologic findings in CUS.
- To highlight diagnostic challenges and treatment considerations.
- To explore the etiology and pathogenesis of CUS.
Main Methods:
- Surgical biopsy for histopathology.
- Direct and indirect immunofluorescence microscopy.
- Identification of autoantibodies via immunofluorescence.
Main Results:
- CUS affects white women in late middle age.
- Histology shows non-specific chronic inflammation.
- Autoantibodies to DeltaNp63alpha are detected in circulation and tissue.
Conclusions:
- Accurate CUS diagnosis is crucial due to limited glucocorticoid efficacy.
- Hydroxychloroquine shows therapeutic benefit.
- Etiology and pathogenesis remain unknown, necessitating further research.

01:17Chronic Bowel Disorders: Introduction
Chronic bowel diseases are a group of long-term conditions affecting the digestive tract, characterized by inflammation and damage to the gut lining. These conditions primarily include irritable bowel syndrome and inflammatory bowel disease.
Irritable Bowel Syndrome (IBS) is a common disorder affecting the gastrointestinal tract. The distinctive feature is recurrent abdominal pain associated with altered bowel movements, manifesting as constipation, diarrhea, or fluctuating between both. The...

01:25Chronic Pancreatitis I: Introduction
Chronic pancreatitis is a long-standing, relapsing inflammation of the pancreas, characterized by irreversible damage to the gland. It results in progressive destruction of the pancreatic parenchyma, fibrosis, and eventual loss of both exocrine and endocrine function. The disease may evolve gradually after multiple episodes of acute pancreatitis or develop independently.EtiologyChronic pancreatitis can arise from a variety of causes:Alcohol use is the leading cause, accounting for 70–80% of...
01:24Chronic Pancreatitis I: Introduction
The pancreas, an elongated and flat gland situated behind the stomach, serves a vital function in digesting food and managing blood sugar levels.
Pancreatitis is the inflammation of the pancreas, which occurs when the immune system becomes active and causes swelling, pain, and disruptions in organ function. Pancreatitis can manifest as either an acute or chronic condition.
Acute pancreatitis arises suddenly and lasts for a brief duration, while chronic pancreatitis is a long-term affliction...

01:20Inflammatory Bowel Disease II: Ulcerative Colitis
Ulcerative colitis is a chronic inflammatory disorder of the colon characterized by continuous mucosal inflammation that typically begins in the rectum and extends proximally in a uniform pattern. Its pathogenesis involves a complex interplay of genetic predisposition, immune dysregulation, and environmental influences. These factors converge to impair the colon’s epithelial defenses and promote an exaggerated inflammatory response against luminal contents.Breakdown of the Mucosal BarrierA...
01:21Chronic Pancreatitis II: Pathophysiology
Chronic pancreatitis is a progressive and irreversible inflammation of the pancreas, most often caused by long-term alcohol abuse, but it can also be related to ductal obstruction, smoking, or genetic factors.Chronic pancreatitis occurs when the pancreas is repeatedly exposed to harmful agents like alcohol, smoking, ductal obstruction, or genetic predisposition. These factors lead to the release of toxic metabolites and inflammatory cytokines, sustaining chronic inflammation in the pancreatic...

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...
