Summary

Here is a summary of the general studies that have been conducted on Inflammatory Diseases (eg, Rare Diseases beginning with the letter "I" or "N"), as well as which diseases are commonly found.

There are big differences between the early study (circa 1900-1980), where they often only discovered diseases that *occurred*, and modern studies (1990s onwards), where they have improved the science of why the diseases occur and how treatment issues can be improved.

### 1. From the period 1900–1980: Common diseases
During this period, it was mainly investigated whether diseases were occurring in certain groups. The study was often based on epidemiological follow-ups and was less detailed with specific mechanisms.

* Rare diseases that start with the letter:
* In: Non-acute porphyria, Inflammatory myofibroma (or *inflammatory myofibroma*), Immune-mediated enterocolitis and Immune-mediated myositis (or *immune-mediated myositis*).
* J: Giant cell arteritis (or *giant cell arteritis*), Juvenile chronic myelomonocytic leukemia (or *juvenile chronic myelomonocytic leukemia*), Juvenile psoriatic arthritis, Rare diseases that start with the letter that starts with the letter like "I".
* K: Cold hemolytic anemia and *Cold hemolytic anemia*.
* L: Langerhans cell histiocytosis, *Langerhans cell sarcoma*, Laryngeal squamous cell carcinoma, *Leiomyosarcoma* (or *leiomyosarcoma*, *leiomyosarcoma*, *leiomyosarcoma*).
* M: *Gastrointestinal disease* in cystic fibrosis, *Malignant* tumor of the dermis, *Malignant tumor of the central nervous system* (or *Malignant tumor of the central nervous system*).
* P: *Paraneoplastic Neurological Syndrome* and *Pegs* (or *Paraneoplastic Neurological Syndrome*).
* S: *SAPHO syndrome*, *Sarcoid*, *Sarcoma*, *Selective lack of polysaccharide antibody* and *Shprintzen-Goldberg syndrome*.
* T: *T-cell lymphoma* and *T-alpha*-, *T-beta*-, *T-syndrome* and *Thalassemia*.
* V: *Volume* (or *wagon*), *Volume* (or *wagon*), *Volume* (or *wagon*), *Vern* and *Veg* and *Vess* (or *vas*) and *Vern* (or *wagon*).

* Previous studies often focused on *why* the diseases were present (example: if they were swallowed in a specific family), but they were less twisted than today.*

### 2. Modern studies (1990s onwards)
Modern genetics has revolutionized knowledge. The incidence has often disappeared because we already know exactly what the diseases are and how they occur. The focus has shifted from just "seeing" the diseases to analyzing them through genetics, immunological methods and biological models.

#### A. Genetic studies and disease patterns
* *Rare diseases that start with the letter that starts with the letter like "I"*: Genetic studies have changed a lot. Now we know that the diseases are often linked to genes (eg *BCL2* in immune-mediated enterocolitis, *TP53* in malignant tumors), while others are sufficiently unspecific. There are now "familial" variants that occur in certain groups.
* *Non-acute porphyria* and *Inflammatory myofibroma*: Genetic studies show that a specific gene (eg *IL-17*, *IFN-γ*) is sufficient for the diseases to be rare.
* *Rare diseases that start with the letter "J"*: By studying *GATA2*, *STAT1*, *STAT6* and *HIF-1α*, it has been possible to identify specific gene regions for the diseases.

#### B. Immunological studies (Immune media, Immune deficiency, Immune mediated)
* Immune deficiency: One has much more depth introduced through immunological models than before.
* Immune-mediated enterocolitis: Now there is a complete genetic review to show how *IL-17* and *IL-23* create inflammation.
* Immune-mediated myositis: By studying *CD19/CD20* and *CD79b* we found average values ​​that were much weaker than before.
* Immunoglobulin G4-related disease: This is a new and very important group that has existed in the last
