Rheumatoid arthritis (RA) nodules

By SWA

 Rheumatoid arthritis are associated with firm, non-tender bumps underneath the skin, near joints.

These nodules are typically composed of a mixture of different substances, including fibrinoid material. Rheumatoid arthritis (RA) nodules are a common feature of rheumatoid arthritis, a chronic autoimmune disease that primarily affects the joints.

Fibrinoid material is a term used to describe a substance that resembles fibrin, a protein involved in the blood clotting process. In the context of rheumatoid arthritis nodules, fibrinoid material can accumulate within the nodules. These nodules are often found in various tissues, including the skin, near joints, and in internal organs.

Rheumatoid arthritis nodules are a result of chronic inflammation and immune system dysfunction in individuals with RA. They can vary in size and may be painless or painful, depending on their location and size. These nodules are not unique to rheumatoid arthritis and can sometimes be seen in other conditions, such as systemic lupus erythematosus.

It's important for individuals with rheumatoid arthritis who develop nodules to consult with a healthcare provider for proper evaluation and management, as treatment options may be considered depending on their size and location and whether they are causing any symptoms or functional impairment.

In RA nodules, fibrinoid material is more commonly associated with the chronic inflammatory response in the affected tissues, including the formation of these nodules. It's not directly involved in the formation of pathological blood clots. 

However, it's important to note that people with rheumatoid arthritis may have an increased risk of developing certain cardiovascular complications, including atherosclerosis (narrowing of the arteries), which can lead to an increased risk of thrombosis in affected blood vessels. This increased risk is thought to be related to the chronic inflammation and immune system dysregulation associated with RA.

Schnitzler Syndrome: A Rare Autoinflammatory Disorder

By SWA
Schnitzler syndrome is a rare, chronic autoinflammatory disease characterized by chronic urticaria (hives), recurrent fever, joint pain, and monoclonal gammopathy (abnormal proteins in the blood). First described by Dr. Liliane Schnitzler in 1972 , this condition is often misdiagnosed, leading to years of untreated symptoms before a correct diagnosis is made. The case report, " A 58-Year-Old Woman With Urticaria, Fever, and Joint Pain " , describes a case that closely aligns with my own experience with this challenging disorder. Key Features of Schnitzler Syndrome Schnitzler syndrome presents with a characteristic set of symptoms, though not all patients experience them in the same way: Chronic Urticaria (Hives) – Persistent, non-itchy or mildly itchy red patches that do not respond to antihistamines. Monoclonal Gammopathy (IgM or IgG type) – Abnormal monoclonal immunoglobulin detected in the blood (most commonly IgM ). Recurrent Fever – Unexplained fever episodes, often...

Dysferlin Protein: Key Roles, Genetic Locations

The purpose of this article is to share and discuss the details of a new discovery, which is highlighted within: CRISPR-Cas9: A Breakthrough Tool to Repair the DYSF Gene The dysferlin protein plays an essential role in maintaining the integrity of muscle cell membranes, particularly in tissues that endure significant mechanical stress, such as skeletal and cardiac muscles . Encoded by the DYSF gene , dysferlin is indispensable for repairing damaged cell membranes after injury caused by muscle contraction or external forces. This article explores the main locations where dysferlin is produced, its role in muscle repair, and supportive nutritional and therapeutic strategies for individuals with dysferlin deficiency, such as those affected by dysferlinopathies (e.g., Limb-Girdle Muscular Dystrophy Type 2B or Miyoshi Myopathy). Currently, there is no definitive answer as to why the severity of dysferlin protein expression or depletion varies. Do pathogens play a role in the methylation o...

Toxic Skin Condition Post-mRNA COVID-19 Vaccination

Identifying Severe Skin Conditions Post-Vaccination Following administration of the BioNTech mRNA vaccine, a small subset of individuals may develop severe and complex reactions. These reactions are often misdiagnosed or misunderstood due to their rarity and diverse presentation. This essay examines a case characterized by severe skin conditions, systemic symptoms, and complications such as hypercalcemia and crystal formation. It highlights the need for accurate diagnosis, holistic management, and increased awareness of these rare but significant vaccine-related adverse events. Initial Symptoms and Misdiagnoses Severe symptoms began shortly after the first dose of the BioNTech vaccine, initially presenting as petechiae, diagnosed by a rheumatologist. However, following the second dose, symptoms rapidly escalated, resulting in intense burning pain and thinning of the skin. The skin on the legs and thighs became paper-thin and could tear with the slightest touch, with the affected area e...
