Summary
Riga-Fede disease is a chronic traumatic ulcer in infants caused by teeth. This condition mimics oral cancer, but prompt dental management ensures healing.
Area of Science:
- Oral Pathology
- Pediatric Dentistry
Background:
- Traumatic ulcerations of the oral mucosa are common, typically resolving within days.
- Chronic forms can present as reactive, exophytic lesions, including traumatic ulcerative granuloma with stromal eosinophilia (TUGSE).
Observation:
- Riga-Fede disease (RFD) is a specific type of TUGSE occurring in infants.
- It results from chronic mucosal trauma by mandibular anterior primary teeth during nursing.
- Clinical presentation can be concerning, resembling squamous cell carcinoma.
Findings:
- RFD is not frequently reported, leading to unfamiliarity among dental practitioners.
- The case presents a large Riga-Fede lesion in an infant.
Implications:
- Early recognition and diagnosis of RFD are crucial for appropriate clinical management.
- Understanding RFD can prevent misdiagnosis and unnecessary patient anxiety.
- This case highlights the importance of recognizing benign reactive lesions in pediatric oral mucosa.

01:23Rheumatic Heart Disease I: Introduction
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...

The key clinical manifestations of Rheumatic heart disease (RHD) include several distinct cardiac symptoms.Carditis, a hallmark of acute rheumatic fever, involves inflammation of the heart's endocardium, myocardium, and pericardium. Chronic RHD often results from recurrent episodes of carditis. Its symptoms include the following:Murmurs are caused by valvular damage, especially to the mitral and aortic valves. Mitral stenosis or regurgitation is common, with characteristic heart murmurs...
01:26Rocky Mountain Spotted Fever
Rocky Mountain Spotted Fever (RMSF) is a severe tick-borne illness caused by Rickettsia rickettsii, a Gram-negative, coccobacillary bacterium. This pathogen is an obligate intracellular parasite, requiring a host cell for replication. Transmission occurs through the bite of an infected tick. In the United States, the most important vectors are Dermacentor variabilis (American dog tick) and Dermacentor andersoni (Rocky Mountain wood tick), though other tick species may also serve as vectors.
01:03Rous Sarcoma Virus (RSV) and Cancer
Rous Sarcoma virus or RSV was discovered by F. Peyton Rous in the year 1911 as a filterable transmissible agent that could cause tumors in chickens. He won a Nobel Prize for this discovery in 1966. His experiments clearly demonstrated that some cancers could be caused by infectious agents and led to the discovery of many more cancer-causing viruses in animals as well as humans.

01:21Rheumatic Heart Disease III: Medical Management
Rheumatic heart disease (RHD) management can be divided into two main strategies: prevention and long-term management.Primary PreventionPrimary prevention focuses on timely diagnosis and management of group A streptococcal pharyngitis to prevent acute rheumatic fever. The most widely used antibiotic for treating this condition is intramuscular benzathine penicillin G.Acute Rheumatic Fever TreatmentThe primary treatment goal for a patient diagnosed with acute rheumatic fever is to suppress the...
