Introduction:
Intestinal perforation due to ingestion of a foreign body accounts for 21% of the total in our hospital.
Methods:
All cases of intestinal perforation due to foreign body ingestion occurring since 1990 were collected (29 cases), and the visual characteristics of these patients were analysed.
Results And Discussion:
The mean age was 74.2 years (all of them presbyopic) with the majority being female (1.9:1). The most frequently ingested foreign body was fish bone (55%). The corrected near visual acuity obtained a mean value of 0.73, while the real visual accuity (only one of them wore glasses to eat) was 0.145. Four patients (20%) had only one eye, and the TNO test was positive in only 12 (60%). At least 13 (65%) had some degree of cataract.
Conclusions:
Improving near visual acuity with either early cataract surgery and/or multifocal intraocular lenses may decrease the number of gastrointestinal perforations.

Inflammatory 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...

Inflammatory 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...
