[Intrauterine device and pelvic inflammatory disease: Myth or reality?]
Introduction:
Intrauterine device (IUD) is a reliable contraceptive method that is long term reversible, and well tolerated. Numerous studies prove its efficiency and report rare complications that are attributed to it. However, its use is limited due to fear that it can cause a pelvic inflammatory disease (PID). This is based on historical data on infections related to the "Dalkon Shield", which was removed from the market in 1974.
Method:
The analyzed articles were extracted from PUBMED database between 2000 and 2016. In total, 22 studies were retained. A meta-analysis was not possible due to the methodological diversity among the selected articles contributing to this narrative review of the literature.
Results:
After analysis, the following factors influence the risk of PID linked to IUDs: an advanced age and sexually transmitted infections.
Conclusion:
The risk of PID linked to IUDs is lower than 1%. This is explained by new models of IUD, better screening tests, more frequent follow-up of the patients and the improvement of care PID patients. In the light of our results, the threat of pelvic inflammatory disease should not hinder the use of IUDs.

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.

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...

Diagnostic studies
A colonoscopy is the definitive screening test, distinguishing ulcerative colitis from other colon diseases with similar symptoms. During a colonoscopy test, inflamed mucosa with exudate ulcerations can be observed, and biopsies are taken to determine the histologic characteristics of the...
