Summary
Reactive arthritis is uncommon in older adults. This case highlights a rare instance of old-onset reactive arthritis following a Group C streptococcal infection, successfully treated with steroids and infliximab.
Area of Science:
- Rheumatology
- Infectious Diseases
- Immunology
Background:
- Reactive arthritis typically affects individuals aged 20-40.
- Common triggers include enteric and urogenital infections.
- Association with Group C and G streptococcal infections is rare.
Observation:
- An 81-year-old woman presented with bilateral sacroiliitis.
- The condition followed a Group C streptococcal infection.
- This represents an unusual case of old-onset reactive arthritis.
Findings:
- Successful treatment of old-onset reactive arthritis was achieved.
- Treatment involved a steroid taper combined with infliximab.
- This demonstrates a viable therapeutic approach for elderly patients.
Implications:
- Expands understanding of reactive arthritis triggers in the elderly.
- Suggests streptococcal infections as a potential cause in older populations.
- Highlights the efficacy of immunomodulatory therapy in late-onset cases.

01:23Rheumatic Heart Disease I: Introduction
57
Rheumatic heart disease or RHD is a chronic condition that results from rheumatic fever, causing permanent damage to the heart valves.Etiology and Risk FactorsIt primarily arises from rheumatic fever, an inflammatory disease that can develop after untreated or inadequately treated group A streptococcal (GAS) pharyngitis. Streptococcus spreads through direct contact with oral or respiratory secretions. While the bacteria are the causative agents, factors like malnutrition, overcrowding, poor...

137
Spirochetes, unique bacteria in the phylum Spirochaetes, are gram-negative, motile, tightly coiled, slender, and flexible. They inhabit aquatic sediments and animals, with some causing diseases like syphilis. Spirochetes are classified into eight genera based on habitat, pathogenicity, phylogeny, and characteristics.Their distinctive motility arises from endoflagella, located within the cell’s periplasm. These endoflagella anchor at the cell poles and extend along the cell length, encased...

Introduction
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.

59
Introduction:For diagnosing acute pyelonephritis, a comprehensive patient history is collected to identify symptoms such as dysuria, frequent or urgent urination, flank pain, or costovertebral angle (CVA) tenderness that may suggest a kidney infection.Physical ExaminationDuring the physical examination, CVA tenderness is assessed. This involves gentle percussion over the costovertebral angle, where tenderness often indicates a kidney infection.Diagnostic TestsUrinalysis: Used to identify white...

01:17Chronic Bowel Disorders: Introduction
548
Chronic bowel diseases are a group of long-term conditions affecting the digestive tract, characterized by inflammation and damage to the gut lining. These conditions primarily include irritable bowel syndrome and inflammatory bowel disease.
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...
