Abstract:
A 17-year-old boy developed prominent mediastinal and subcutaneous emphysema while receiving treatment with 5-aminosalicylic acid (5-ASA) and oral corticosteroids for severe ulcerative colitis. We ruled out infection and initiated oral administration of tacrolimus, after which both the underlying disease and mediastinal and subcutaneous emphysema improved. However, he continued to experience repeated bouts of ulcerative colitis, so we ultimately opted for surgical intervention. Although mediastinal and subcutaneous emphysema is rare, it is one of the known extra-intestinal complications and can be particularly concerning. In this patient, mediastinal and subcutaneous emphysema might have been caused by the vulnerability of pulmonary alveolar walls to steroid medication and the increase of pulmonary alveolar pressure with abdominal pain and breath holding. Here, we report a case of inflammatory bowel disease with mediastinal and subcutaneous emphysema, along with a review of the literature.

01:27Inflammatory Bowel Disease I: Ulcerative Colitis
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...

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...
01:30Inflammatory Bowel Disease II: Crohn's Disease
Inflammatory bowel disease, commonly known as IBD, refers to a collection of disorders that lead to persistent inflammation of the gastrointestinal tract. The two types of IBD are ulcerative colitis, which impacts the colon, and Crohn's disease, which can involve any part of the gastrointestinal segment.
Crohn's disease
Crohn's disease is a chronic, systemic inflammatory bowel disease (IBD) that predominantly affects the gastrointestinal tract. It is marked by...

Smoking is a primary risk factor for COPD, with over 80% of patients having a history of it. Patients typically experience progressive dyspnea or labored breathing, frequent coughing, and recurrent pulmonary infections. Many eventually succumb to respiratory failure, characterized by...
