Rous Sarcoma Virus (RSV) and Cancer01:03

Rous Sarcoma Virus (RSV) and Cancer

5.9K
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...

Endocarditis II: Clinical Features of Infective Endocarditis

240
Endocarditis can present various clinical features depending on the causative organism and the patient's underlying health conditions. Initially, the clinical features of infective endocarditis develop gradually, presenting with nonspecific symptoms that can be easily mistaken for other illnesses.General SymptomsEarly symptoms of infective endocarditis are fever, chills, weakness, malaise, fatigue, and weight loss. These symptoms reflect the systemic nature of the infection and the body's...

Single Nucleotide Polymorphisms-SNPs

17.7K
A single nucleotide polymorphism or SNP is a single nucleotide variation at a specific genomic position in a large population. It is the most prevalent type of sequence variation found in the human genome. Point mutations that occur in more than 1% of the population qualify as SNPs. These are present once every 1000 nucleotides on an average in the human genome. Replacement of a purine with another purine (A/G) or a pyrimidine with another pyrimidine (C/T) is known as a transition. In contrast,...

Common Respiratory Disorders01:31

Common Respiratory Disorders

1.1K
Respiratory disorders, a prevalent health concern globally, are generally divided into two primary categories: upper and lower respiratory tract disorders. The categorization is based on the area of the respiratory system they affect.
Upper respiratory disorders impact the airways above the vocal cords, encompassing areas like the nose, sinuses, and throat. Various conditions fall under this category, including the common cold and allergic rhinitis. These disorders can stem from several causes,...

Viral Recombination00:57

Viral Recombination

24.6K
Cells are sometimes infected by more than one virus at once. When two viruses disassemble to expose their genomes for replication in the same cell, similar regions of their genomes can pair together and exchange sequences in a process called recombination. Alternatively, viruses with segmented genomes can swap segments in a process called reassortment.

Rheumatic Heart Disease II: Clinical Manifestations and Diagnostic Studies

292
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...

Area of Science:

  • Infectious Diseases
  • Dermatology
  • Virology

Background:

  • Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) emerged in 2019, causing the COVID-19 pandemic.
  • While primarily affecting the respiratory system, SARS-CoV-2 can impact multiple organs, leading to multi-organ dysfunction.

Observation:

  • Dermatologic manifestations of COVID-19 are increasingly reported but lack a clear pattern.
  • This report details a case of a 78-year-old male with SARS-CoV-2 infection presenting with a diffuse morbilliform rash as the primary symptom.

Findings:

  • The patient tested positive for SARS-CoV-2, exhibiting a rash on the trunk and back without initial respiratory symptoms.
  • Fever developed subsequently, but respiratory complications were absent. The rash resolved with topical steroids and oral antihistamines.

Implications:

  • Recognizing diverse clinical presentations, including dermatologic signs like rash, is crucial for early COVID-19 diagnosis and management.
  • Reporting unusual manifestations aids in understanding the virus's full spectrum and implementing appropriate isolation and containment measures.
