The Retinoblastoma Gene

The Retinoblastoma Gene

Tumor suppressor genes are normal genes that can slow down cell division, repair DNA mistakes, or program the cells for apoptosis in case of irreparable damage. Hence, they play an essential role in preventing the proliferation of damaged cells.
The first-ever tumor suppressor gene called Rb was identified in retinoblastoma - a rare eye tumor in children. In inherited forms of the disease, a child inherits one defective copy of the Rb gene, which predisposes them to retinoblastoma. However,...

Rous Sarcoma Virus (RSV) and Cancer

Rous 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.
RSV is a retrovirus that contains two copies of a plus-strand RNA genome. Its genome consists of four main open...

Pediatric Cardiology

|June 5, 2009

Summary

A rare cardiac inflammatory pseudotumor, likely infectious, was diagnosed and treated. Surgical removal resolved the patient's unexplained sinus tachycardia, highlighting the importance of imaging and surgery.

Area of Science:

Cardiology
Pathology
Infectious Diseases

Background:

Cardiac inflammatory pseudotumors are rare, often challenging to diagnose.
Infectious etiologies represent a specific and uncommon subset of these tumors.

Observation:

A unique case presented with unexplained sinus tachycardia.
The tachycardia resolved completely following surgical tumor resection.

Findings:

The reported case is a rare cardiac inflammatory pseudotumor with an infectious origin.
Surgical resection was both diagnostic and curative, resolving associated tachycardia.

Implications:

This case underscores the value of combining multiple imaging modalities for diagnosis.
